Greedy Routing Enables Network Navigation Without a Map

first_img Algorithm explains how ants create and repair trail networks This correlation between a node’s distance to the destination in metric space, the node’s overall reach, and its degree is what makes the greedy routing strategy efficient at determining the shortest paths. In most cases of transferring information with greedy routing, information first travels to nodes with high degrees. Then, when the distance to the destination decreases, the pattern changes so that the information reaches its destination in a few small hops, regardless of node degree.As the researchers explain, complex networks have a peculiar structure that makes them navigable and that guarantees that information can flow along the shortest routes even without knowledge of the network’s global topology. Regardless of the specifics of the hidden metric space, greedy paths are the shortest paths in synthetic networks with the topologies of real complex networks. Still, the study leaves open some questions, such as the possibility that real networks may tend to evolve to become navigable, as well as determining which networks have hidden metric spaces and which do not. Using the greedy routing strategy to find the shortest paths for the Internet could greatly improve the efficiency of routing in the Internet, Today, Internet routers must continually update their global topology knowledge, presenting a major scalability bottleneck in Internet growth.“Routing in the Internet today requires global topological awareness for all routers, which involves enormous and ever-growing inter-router communication overhead,” Krioukov explained. “Routers are constantly detecting, distributing, processing, and recalculating information needed to compute the shortest paths. For example, as soon as a link fails, the adjacent routers send messages to their neighboring routers about this event, those send messages to their neighbors, and so on, resulting in huge and never-abating cascades of routing updates and recalculations. Routers are getting overwhelmed with this overhead. They can’t keep up with it, they fail, and black holes – unreachable islands of the Internet – are appearing everywhere.“With greedy routing, global topology knowledge is not needed, so that this overhead would be removed, and routing would scale and work much better,” he said.More information: Boguna, Marián; and Krioukov, Dmitri. “Navigating Ultrasmall Worlds in Ultrashort Time.” Physical Review Letters 102, 058701 (2009).Copyright 2009 PhysOrg.com.

However, a navigation technique called greedy routing has shown that it can find the shortest paths between nodes using only local information, without knowledge of the network’s global topology. Marián Boguna from the University of Barcelona and Dmitri Krioukov from the University of California, San Diego, have shown in a recent study that random, scale-free networks such as the Internet have a peculiar structure that enables information to flow along the shortest routes without global topology knowledge. The surprising results are published in a recent issue of Physical Review Letters.“As common sense suggests, the computation of shortest paths is commonly believed to require the full and precise knowledge of the full topology, and here we are showing that it’s in fact not true – not true for the topologies of real complex networks,” Krioukov told PhysOrg.com.In greedy routing, a node passes information to the neighboring node that is closest to the final destination in an abstract space called hidden metric space. This space underlies the real network, and distances in this space abstract intrinsic similarities between nodes. The existence of hidden metric spaces under real networks is a conjecture, although researchers have found evidence of their existence for some real networks, including the Internet.As the researchers explain, some types of networks are not navigable. For instance, if the probability that two nodes are linked doesn’t depend on the metric distance between them, then such networks are difficult to navigate, as there is no way to choose one node over another based on distance. But when there is a connection between the link existence probability and the hidden distance between nodes, metric distances can help to navigate the network, i.e., such networks are “navigable.”As the scientists explain, an ideal navigating strategy should first pass the information to high-degree nodes, since their numerous connections likely cover long distances, getting closer to the destination node. However, greedy routing doesn’t check nodes’ degrees, but only compares the underlying metric distances between various neighbor nodes and the destination node. Fortunately, as the researchers show for navigable networks, node degree is positively correlated with the distances that the node covers by its links. So the closer to the destination a node is, the more distance it likely reaches, and the higher the degree of the node.

Navigating the Internet – or any similar network – generally works most efficiently when routers have knowledge of the network’s global topology. Without knowing the links between nodes, it’s difficult to determine the shortest path between two nodes.last_img read more

Why the sandfish lizard wriggles as it does w Video

Now scientists in the US have created a computer model that emulates the physics of the lizard and other burrowing animals. Play Video credit: Daniel Goldman Goldman’s team then built a snake-like robot capable of moving in a similar way to the living lizard, and were able to control the extent of bending and wriggling as the robot moved. They filmed the robot moving through sand to determine how the amount of curling affected their movements.The team followed with computer simulations of the lizards swimming through a field of beads 3mm in diameter. Even with 3 mm beads rather than tiny grains of sand, the simulations needed the computing power of 20-30 ordinary PCs to run, and still took several days. They used the simulation to analyze the movement of every bead affected by the passing lizard. Both the living lizard and robot swam through the glass beads in the same way as they did through sand.The simulation and robotic tests both gave the same answer: if the lizards curl too little they cannot provide enough power to push through the sand, while if they curl too much they do not move very far forward as they wriggle. The movements of the living lizard are close to optimum. Dr Goldman also said the studies suggest that sandfish lizards dive into the sand and wriggle down into it to escape from predators as fast as possible. Burrowing into the sand also enables them to escape the scorching heat of the desert.As a result of their experiments Goldman’s team were able to derive a mathematical theory and highly predictive computer model capable of emulating the physics of sand and objects or animals moving through it. Dr Goldman said the model is the first really detailed, quantitative and accurate model of objects moving through an environment other than air or water.The research could find applications in a number of fields involving objects beneath the surface, such as earthquake monitoring and landmine detection. It could also lead to robots designed to wriggle into the sub-surface on other planets, and the team is already talking to NASA representatives about the possibilities. Explore further Professor Daniel Goldman of the Complex Rheology And Biomechanics Laboratory (CRAB Lab) at the Georgia Institute of Technology in Atlanta, said it is not easy to study the movements of burrowing animals because sand grains bounce off each other wildly rather than creating the kind of flowing movements found when animals move through water or air.Previous studies using X-rays revealed that the sandfish lizard moves through the sand by wriggling in S-shaped curves with their legs tucked in. Dr. Goldman said the wriggling movements of the lizard enable it to move at great speed, since it can cover two body lengths every second, but it was unclear at that time exactly how they achieve those speeds in sand.

Couple finds evidence indicating earliest humans lived by rivers and streams

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. More information: River-margin habitat of Ardipithecus ramidus at Aramis, Ethiopia 4.4 million years ago, Nature Communications 2, Article number: 602 doi:10.1038/ncomms1610AbstractThe nature and type of landscape that hominins (early humans) frequented has been of considerable interest. The recent works on Ardipithecus ramidus, a 4.4 million years old hominin found at Middle Awash, Ethiopia, provided critical information about the early part of human evolution. However, habitat characterization of this basal hominin has been highly contested. Here we present new sedimentological and stable isotopic (carbon and oxygen) data from Aramis, where the in situ, partial skeleton of Ar. ramidus (nicknamed ‘Ardi’) was excavated. These data are interpreted to indicate the presence of major rivers and associated mixed vegetations (grasses and trees) in adjacent floodplains. Our finding suggests that, in contrast to a woodland habitat far from a river, Ar. ramidus lived in a river-margin forest in an otherwise savanna (wooded grassland) landscape at Aramis, Ethiopia. Correct interpretation of habitat of Ar. ramidus is crucial for proper assessment of causes and mechanisms of early hominin evolution, including the development of bipedalism. Image: USGS Explore furthercenter_img Now new evidence has come to light that suggests the former might be more likely. Husband and wife team Royhan and Nahid Gani have been studying the sediments surrounding the place where Ardipithecus ramidus, aka, “Ardi,” was found in Ethiopia, and have, as they describe in their paper published in Nature Communications, found that most of the evidence in the area points to a group of people that lived near a very large river.Ardi is believed to have lived some four and half million years ago in what is now Aramis, a hot and dry part of Ethiopia, but until now, no serious study had been done on the dirt in which the skeletal remains were found. After doing so, the Gani’s discovered that the dirt was actually layers of sandstone that appear most likely to have been the result of an ancient stream overflowing it’s banks periodically, leaving behind layers of sand. Branching out, the team discovered that the sediments indicated that such a stream was actually a river, likely twenty six feet deep and over twelve hundred feet wide.Next they turned their attention to plant material that had been preserved in the sandstone, measuring their isotopes, and found that the material had come from grassy plants, suggesting a savannah type environment. But once again, widening their area of study, they also found that there were wide changes in the types of plant material in the area. This caused them to surmise that there were patches of forests near the rivers and streams.Based on these two pieces of information, the team suggests that it appears Ardi, who many researchers believe is our oldest found ancestor, lived in a savannah, near fresh flowing water. Some suggest that such an environment would be consistent with learning to walk upright to see over the tall grasses. (PhysOrg.com) — When many people think of our earliest human ancestors, they think of the hot dried out dusty environments in Africa in which many of their remains were found. Unfortunately, such images don’t take into account the changes in environment that have occurred since those times when early peoples walked the Earth. Archeologists of course have thought of such things and for many years have tossed ideas back and forth debating whether such people lived by rivers and streams, as did those that came later and built civilization along such places as the Nile or whether they lived in woodlands.

Astronomers study star formation and gas flows in the galaxy NGC 1365

first_img Ultra-luminous infrared galaxy with strong ionized-gas outflow discovered Located some 56 million light years away in the Fornax cluster, NGC 1365, dubbed the Great Barred Spiral Galaxy, is a barred spiral and ringed galaxy of Seyfert type. Although many observations of NGC 1365 have been conducted to date, it has not been yet thoroughly studied at mid-infrared wavelengths.In general, mid-infrared observations have the potential to uncover crucial details about molecular gas clouds and ionized gas, which is key to study the distribution and kinematics of the mass-dominating old stellar population in galaxies. Such observations could also provide important information on star formation history and properties of central engines of galaxies.A team of European astronomers led by Nastaran Fazeli of University of Cologne in Germany performed near-infrared observations of NGC 1365 hoping to learn more insights into gas and stellar kinematics in this galaxy. In their observational campaign, the researchers concentrated on the approximately 2,600-light-year-wide circumnuclear region of NGC 1365, studying it using the Spectrograph for INtegral Field Observations in the Near Infrared (SINFONI) instrument on VLT in Chile.”In the framework of understanding the gas and stellar kinematics and their relations to AGNs [active galactic nuclei] and galaxy evolution scenarios, we present spatially resolved distributions and kinematics of the stars and gas in the central ~800-pc radius of the nearby Seyfert galaxy NGC 1365,” the astronomers wrote in the paper.SINFONI observations resulted in detecting parts of the starburst circumnuclear ring (with a radius of about 3,260 light years) and resolving some weaker starburst regions within the inner ring and the nucleus (radius of approximately 1,000 light years). The researchers found that the circumnuclear ring has strong emitting “hot spots” in optical wavelengths, which have starburst ages below 10 million years with an age gradient on the west side of the ring. The study also revealed strong broad and narrow emission-line components of ionized gas in the nuclear region, as well as hot dust with a temperature of approximately 1,300 K. The researchers noted that these properties are typical for type 1 AGN.Observations indicate that the stellar velocity field of NGC 1365 shows an overall rotation. Moreover, ionized and molecular gas show an overall rotation in the general orientation with the stellar velocity.The astronomers calculated that the galaxy’s black hole mass is from five to 10 million times greater than the mass of our sun. They found that the hot molecular gas is around 615 solar masses, what corresponds to a cold molecular gas mass at a level between 200 and 800 million solar masses. Additionally, the ionized gas mass was estimated to be about 5.3 million solar masses. Using European Southern Observatory’s Very Large Telescope (VLT), astronomers have investigated the galaxy NGC 1365. The study, presented in a paper published January 18 on the arXiv.org pre-print server, reveals essential insights about star formation processes and gas flows in this galaxy.

Also Read – Lightning kills 8, injures 16 in stateTen teachers have been recruited for this department. “The teachers are doctorates hence PhD courses will also be offered,” said Dr Bhattacharyya. Specialisation in Pharmacology and Pharmaceutics will be offered for the M Pharm course. The V-C stated that the university will apply for B. Pharm course from next year. “There is no B Pharm course in North Bengal. It is in great demand. We will try to introduce this course from next year,” said the V-C. For the Masters Degree in Food Processing, 24 students will be allowed to pursue this course in the present academic session. Last year, the university had started an integrated course in Geology (5 year long course, including B Sc and M Sc.) “We are starting a similar integrated course in Anthropology from this academic year,” said the V-C. Two new buildings are coming up for science and humanities streams. “Both the buildings will be six-storied. Each floor in the science building is 15000 sq ft. The new disciplines will be housed in the science building,” the V-C said. To ensure that students get proper placement, the university has approached the state government to create a post of a full-fledged placement officer. “The placement officer will liaison with different companies and help students get placement. Till a post is sanctioned we will tie up with some agency or individual on contractual basis,” added Bhattacharyya. The University of North Bengal in Siliguri was founded in 1962.last_img read more

Royal Karma The King who was Accidentally Burnt Alive

first_imgKarma, the doctrine of inevitable consequence. The universal principle of retributive justice determining one person’s state of affairs. King Charles II of Navarre, infamously deemed “The Bad One” for his countless malicious wrongdoings, was a two-faced treacherous human being whose duplicitous dealings and constant scheming led him to realize the faithfulness of this doctrine probably better than anyone else.But let us roll back in time and see how karma caught up with Charles, the curious individual whose life stands to prove that men are sometimes not punished for their sins, but by them.Charles II of Navarre.Charles II, born Carlos El Malo in Évreux, Normandy, to Philip III, Count of Évreux, and Jeanne, the only surviving child of Louise X, the king of France and Navarre, carried a grudge against the crown of France for as long as he could remember.His mother should have been next in line to the throne when her father died in 1316. Except she was denied this right for she was not a man, and the crown went to her uncle, Philip de Valois, or Philip “The Tall” who allegedly first poisoned his own nephew, John I Posthumous, and then loudly advocated that French tradition excluded women from the line of succession.Louis X, king of France and Navarre.As the closest male heir in line and backed by the French Lords who were not so eager to be ruled by a woman, Philip was crowned King of France and Navarre the same year in November.To sweeten things up, he awarded lands in Champagne and Brie in the north-east of France to his niece Jeanne — provided she married Philip II of Évreux and denounced her rights to the throne.When he died 6 years later, however, the Navarrese people pledged allegiance to Jeanne instead of giving it to Philip’s successor, his brother Charles IV who inherited the crown in 1322.Carlos, born a decade later on October 10, 1332, found himself in a complicated state of affairs from birth, raised with the notion that when he grew up, he would succeed his mother, inherit the lands of his father in Normandy, and as a direct descendant to King Louis X, rightfully sit on the throne of France.Philip engineered a hasty coronation after the death of his nephew, the young John I, to build support for his bid for the French throne in 1316-17.This was not the case, however. When his mother died and he was crowned King of Navarre in 1349, his right to claim the throne of France was dismissed. According to the same rules and traditions that excluded his mother from any rights of inheritance, he also couldn’t inherit the French crown because he came from a king’s daughter, not a king’s son.To make things even worse, by this time, his mother’s lands in north-eastern France had been taken away from her.John II.So you could see why a boy with crushed hopes, full of wrath, raised by a mother who due to her sex was wrongfully cast aside, dedicated his whole life to right the wrongs that had been done to his family and reclaim everything he thought was rightfully his. He was craving for revenge.Philip’s son, John II, better known as “John the Good,” who was crowned King of France instead of him almost instantly proposed a union between his daughter Joan and Charles II. But while “the Good” king believed the union would be a move in the right direction for the two kingdoms and a small but vital step towards reconciliation, “the Bad” one saw something else in it besides that.John the Good, king of France, ordering the arrest of Charles the Bad, king of Navarre; from the Chroniques of Jean Froissart.Charles married Joan in 1352 but, being well aware that France had ongoing problems with England and King Edward III (a conflict that would later be labeled the “Hundred Years’ War”), he tried to squeeze a sweet deal out of his father in law and asked for Champagne and Brie to be returned to him. But John had already given them to his favorite constable Charles de la Cerda and was not willing to change his mind for the time being.Shortly after the king’s decline, La Cerda was assassinated, with Charles stepping up to take the blame, coolly admitting to the crime as if it was nothing. To add insult to injury, King John II learned his son-in-law bragged about it to King Edward’s closest associates in an attempt to get him on his side. From then on all chances for a real truce were lost between the two kings, but still, John opted to appease his murderous son-in-law, fearful he might switch sides.Edward III, detail from his bronze effigy in Westminster Abbey.John gave him land in Normandy, however Charles betrayed his trust and plotted with the English king nonetheless.Upon learning about his treacherous plans, John had had enough. Charles was imprisoned in Ruen in 1356 from where he escaped, but by the time he did, the kings of France and England already found grounds for peaceful negotiations.He opened up the gates from the prison for every prisoner to escape, asking them to wreak havoc through the streets of Paris in return. Wile John was almost sure that it was the English who did it, Charles went behind his back to the king of England and, once again, offered allegiance to him on condition that they share the spoils if Edward officially recognized him as the rightful ruler of France.Charles II of Navarre.In the meantime, he and John made peace again. There was a peasant’s uprising in France against the Lords in 1358, which Charles first supported in secrecy to gain the trust of the commoners, then switched sides and helped the French aristocracy to suppress the revolt.He arranged a meeting with the peasant leader, whose trust he already had, for truce talks but had him tortured and beheaded when he arrived. A lot of peasants were slaughtered and burned without remorse on his orders during the suppression later on.Historic Noblemen and their ridiculous nicknamesHis double-crossing and double dealings with both France and England went on and on until both John and Edward finally saw right through him. Charles was then forced to return to Navarre and seek other allies or another alternative to achieve his goals. Short of allies, he tried invading France himself. It didn’t work.He lost his lands in Normandy and the trust of the French Lords. He meddled in Spanish affairs and lost everything in France because of it, forced to pay a great deal of money to the Spanish King.Charles V the Wise. Photo by Miniwark CC BY-SA 3.0Finally he tried twice, in 1369 and 1370, to poison Charles V, the King of France, and the son of his longtime ally-enemy John II, “The Good.”Without any help either from the English nor from France, in 1379 his kingdom was sacked and Charles had to surrender 20 fortresses just to keep his status as king over what was left of Navarre after Castilian garrisons rampaged through his homeland.Charles lost the respect of everyone, even his own people. By that time, the Navarrese were fed up with their kings incompetence and the word “Bad” was attributed to him, not for his heinous acts but merely because he was bad at making decisions. They didn’t hate him per se, but let’s say if he was burning and they had water at hand, they’d probably drink it. Which is precisely what happened, figuratively.Pamplona.If the stories are to be believed, ill-struck Charles was confined to his bed in Pamplona on New Year’s Eve in 1386, wrapped up like a cocoon in linen, soaked in distilled wine, or aqua vitae to keep his temperature at bay as per doctors instructions.He was to be sewn into it at bedtime and let the alleged healing powers of the alcohol do the trick overnight. When the maid, acting as an in-house nurse finished wrapping him up, there were no scissors around to cut the thread, and her king was yelling at her to hurry up and be done with it. So she used the candle standing nearby.Street sign indicating the Charles II promenade. Photo by Pitcairn Cc BY SA 4.0The alcohol-soaked king went up flames in an instant, and the maid not knowing what to do allegedly ran away petrified, leaving her king to burn to death right after midnight on January 1, 1387.Read another story from us: King Frederick the Great was a Runaway TeenMost likely, Charles, surrounded by so many who wanted him dead, was assassinated, but there wasn’t any proof left behind. Anyway, most preferred this story. The story about the bad king who, as the saying goes, played with fire all of his life, and got burned to a crisp at the end. A just end, for an unjust human being.last_img read more

Cornering a Missed Pocket of the EdTech Market

first_img Register Now » July 22, 2014 Opinions expressed by Entrepreneur contributors are their own. 4 min read Growing a business sometimes requires thinking outside the box. New technology is changing the way students learn. And as the ed-tech market grows, startups and big technology companies alike are jumping in to provide solutions to meet schools’ changing needs. Just how big is the opportunity?Pegged at an estimated $8 billion in 2013 by the Software & Information Industry Association, the education-technology market is reaching unprecedented heights. According to EdSurge, the ed-ech industry received more than $327 million in venture-capital investment in the second quarter of this year alone.Yet amid the boom in private investment and technology talent migrating into education, entrepreneurs don’t always know how new apps and tools will align with schools’ day-to-day needs. Technology companies would have a better chance of developing products that school systems would actually pay to use, if they had better insight into the market and knew what schools were trying to accomplish as they integrate technology, the variety of tools that schools are currently using and where schools’ demands remain unmet.A new report “Schools and software: What’s now and what’s next” that I co-authored for my organization, the Clayton Christensen Institute, dives into the demand side of ed tech and offers entrepreneurs a glimpse of school systems’ unrealized needs.Here are three tips for entrepreneurs hoping to break into the market:Related: Why Everyone Wants a Piece of Ed Tech1. Small- to medium-size school systems are seeking entrepreneurial help. Although many ed-tech companies organize their sales teams to serve the largest districts, small- to medium-size school systems (serving 2,500 to 25,000 students) educate half of the 48 million public-school students in the United States. Because they have smaller budgets, these systems cannot always access the best-in-their-class solutions for academic and operations software, and some even rely on Excel spreadsheets for basic organizational and accounting tasks.But that leaves a huge untapped customer base in some areas. For example, smaller school systems are eager for integrated back-office software solutions that connect human resources, accounting and student information systems. This would enable school systems of this size to recruit, support and organize employees efficiently.Related: Mark Zuckerberg Puts His Money in Ed-Tech Startup2. Promise better integration with other tools and better data analytics. And schools will follow. Schools are responding enthusiastically to the proliferation of tools in the marketplace: Leaders reported using upwards of 30 different tools in any given school system. But using a variety of point solutions comes at a cost. In fact, schools struggle to integrate software tools within and across departments, and they report that it’s nearly impossible to extract actionable data from many online-learning programs.A few companies, like Clever and Education Elements, are working to address these integration woes. Still, schools need help making their existing software tools talk to one another and are willing to invest in new tools that can help integrate the student data coming out of disparate software programs.Related: Tips for Launching an Ed-Tech Startup3. Stop trying to be everything to everyone. Despite its allure, ed tech risks encountering the same failure that has plagued reformers for years: There is no silver bullet for education. Even if companies peddle one-stop-shop solutions, the schools contacted by my organization are not using singular ed-tech products in a one-size-fits-all manner. Instead, educators are finding that one online-learning program may be great for homework but less suited for in-class assessment. Others may be excellent for drill practice but fall short in promoting deeper learning.These discrete use cases inside classrooms and schools are something that developers and designers need to keep in mind when working with schools. Educators would be delighted to know that a product can do one thing reliably well, rather than do everything with mixed or opaque results. These gaps in the current ed-tech market offer enticing entry points for entrepreneurs interested in the next wave of technology integration in schools.As Alex Hernandez, the co-author of the report and partner at the Charter School Growth Fund, put it, “Both entrepreneurs and schools are getting more sophisticated about the opportunities for software” in kindergarten-to-grade 12 education. “While some challenges are technical, others are about cooperation among vendors and schools. I’m optimistic we can make progress on both fronts.” Related: The Technology That Could Save Schools Thousands Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Globallast_img read more

10 Tips to Make Your App Look Sexy in the App Store

first_img Opinions expressed by Entrepreneur contributors are their own. The number of apps in the App Store has just passed 1.5 million. That’s great news, for Apple at least. For most developers, it mostly means more competition in what’s already a saturated market. While Apple paid developers $10 billion last year, the lion’s share of that money went to less than 1.6 percent of them.Related: Capitalizing on the Millennial Love of Mobile AppsCertainly, a small number of apps do succeed. But as a Nielsen report shows, the average user uses only about 27 apps a month. “Uses” here means the app is opened at least once a month, along with basics such as email, messages, alarm clock, etc.The number of apps used daily is even less encouraging, but that’s another story. The point here is that in the App Store, you compete with 1.5 million apps, and many of the top spots are already taken. Weigh in the App Store’s discoverability issues, and you’re facing some serious marketing challenges. Yet, such competition is far from surprising: The app economy is as hot as it gets. App revenues are growing faster than ever before, and mobile is officially taking over the web — whether that means ecommerce, advertising or search. After all, what’s 1.5 million apps compared to 644 million active websites?To succeed under these circumstances, you need to get noticed. And since the battle for attention takes place in the App Store, here are 10 tips to make your app stand out.1. Focus on regional rankings.The App Store is often called the 1 percent economy because it’s the few apps in the top-25 charts that harvest most of the success. To get into the top-25 chart in the United States, you need at least 100,000 downloads in 72 hours. Getting that kind of traffic requires a huge marketing budget. However, the top-25 charts differ from country to country. So, focus your marketing efforts to dominate regional markets such as the United Kingdom, France or Germany, where the threshold for reaching the top-25 charts is much lower.2. Polish your Appstore SEO (ASO) skills.When it comes to new-app discovery, data shows that 63 percent of iOS users find new apps simply by browsing the App Store. Browsing is followed by friend referrals (50 percent), and browsing the top charts (34 percent). So, make sure your app is easy to find.A common question many entrepreneurs ask our team at Appster about discovery is how exactly to make an app easy to find. The answer is that just as happens with traditional SEO, ASO is about high-volume, low-competition keywords. Apps that include keywords in their title tend to rank better (i.e., Wunderlist: To-do list and Tasks). App descriptions also count, but in any case avoid being spammy.3. Make your icon and screenshots stand out.Your icon and screenshots are some of the most important tools you have to get your app found. Your icon should stand out, look pretty and not be cluttered. The same applies to your screenshots. It’s the first impression that counts, so you want your screenshots beautiful and relevant.4. Include a video.The video is the newest App Store feature, introduced by Apple this past year. Google Play has had it for quite a while. It’s a powerful sales tool, and you should use it. To make it work, take the time to ensure it’s not merely a nice showcase of features. An excellent video involves a mix of storytelling and selling and a strong call-to-action.Related: 6 Time-Tested Tips for Designing a Killer App for Your Brand 5. Get your copywriting text right.Together with video, your description is one of the most important elements for convincing a visitor to download your app. You want to nail the intro line: those first few lines users see before they hit “more” to expand the text. Treat this text as if it were a copy for your Adwords ad. It should be crisp and powerful and state your value proposition in a clear and concise way.6. Consider App Bundles.App Bundles are another relatively recent feature that makes App Store marketing much more potent. App Bundles allows paid apps to be included in bundles of up to 10 apps. The great thing is that these bundles are featured on the App Store’s main “Featured” page, boosting your chances to be found. You can include your app in up to three different bundles, each with its own description, screenshots and a separate listing.7. Use horizontal distribution, if applicable.A great example of horizontal distribution is Udemy. Aside from Udemy’s main app, you can find numerous separate apps, built around specific Udemy tutorials. So, when you search for the brand, you’ll find the main app in the top result. You’ll also find other Udemy apps, such as “Excel tutorial,” “bitcoin tutorial,” “project management course,” “productivity course,” etc.Now, if you were someone searching for productivity, Excel or project management apps, you’d see one of the Udemy apps on your list, too. Obviously, this strategy works only for learning apps, quiz apps and a few other categories.8. Improve your reviews.When it comes to having an influence on conversions, ratings and reviews account for 75 percent, while screenshots and description account for 15 percent and 10 percent, respectively. So, the better your reviews, the more conversions you get.One way to achieve them is to make sure your app is well tested (the majority of one-star reviews complain about frequent crashes). You also want to provide an outlet for customer complaints, as well as technical support.9. Segment your users for better ratings.Another way to improve your ratings is to segment your users into two categories: those who like your app and those who don’t. You can achieve this in the following way: Instead of showing a pop-up asking users to review your app, ask them, “Do you like this app?” If the response is yes, ask them to leave a five-star review; if the answer is no, direct them to your support forum.10. Encourage referrals and word-of-mouth.Referrals are the third most frequent method of new app discovery. There is no specific way to hack this, as it depends on your app. But you still should motivate users to share and make referrals by giving away freebies and other incentives. Likewise, you want to measure your Net Promoter Score and experiment with viral marketing strategies.Obviously, all these tactics are useless if your product stinks. Yet, history has taught us that a mediocre product with great marketing beats a great product with mediocre marketing seven days a week. Work to succeed on both measures.Related: 3 Ways to Make More Money With Your Mobile App Free Webinar | Sept 5: Tips and Tools for Making Progress Toward Important Goals Attend this free webinar and learn how you can maximize efficiency while getting the most critical things done right.

Razer Blade 15 Gets 4K OLED Display 9th Gen Intel Power

first_imgIt’s springtime when a laptop maker’s thoughts turn to system refreshes. And does Razer have a doozy of an update for you. Not only will the Blade 15 (launching April 24 starting at $1,999) be making the jump to Intel’s 9th Gen processors, it will also offer a show-stopping OLED panel.DesignAt 4.6 pounds, 13.9 x 9.3 x 7 inches, the Blade is still one of the smallest gaming laptops on the block. It’s noticeably smaller than the MSI GS65 Stealth Thin (4.1 pounds 14.1 x 9.8 x 0.7 inches) and even the 15-inch Apple MacBook Pro (4 pounds, 13.8 x 9.5 x 0.6 inches). It’s a tad heavier than both systems, but you should have no problem sliding the Blade 15 into a mid-sized bag.MacBook Air vs MacBook Pro: Which 13-inch MacBook Is Right For You?Apple’s entry-level MacBook Air and Pro look pretty similar, but our testing proved they differ in crucial ways.Your Recommended PlaylistVolume 0%Press shift question mark to access a list of keyboard shortcutsKeyboard Shortcutsplay/pauseincrease volumedecrease volumeseek forwardsseek backwardstoggle captionstoggle fullscreenmute/unmuteseek to %SPACE↑↓→←cfm0-9接下来播放Which Cheap Tablet Is Best?

The laptop’s frame is made entirely of pretty matte black CNC aluminum. In typical Razer fashion, the three-headed snake emblem glows invitingly on the lid while a bevy of multicolored lights twinkled on the interior via Razer’s stunning Chroma lighting. It’s like watching a sky on lightning bugs glowing during a lazy summer night.And while black remains Razer’s default color, you can also purchase the laptop in Mercury White if you get one of the Advanced Model configurations.MORE: Which Razer Laptop Is Right for You? Blade vs Stealth vs ProDisplayI never thought I’d see an OLED panel in such a thin-and-light gaming laptop. But here I am, staring at a gorgeous picture of a woman surfing during sunset. It’s hard to look away from the warm marigold sky against the aquamarine water. Details were sharp enough that I saw individual drops of water in the spray as the woman rode the wave towards me. I’m seriously excited to see what Apex Legends, Devil May Cry 5 and Battlefield V among other titles look like on this bad boy.So let’s talk numbers. The Blade 15’s 15.6-inch OLED touch panel is 4K (3840 x 2160) with a 60-Hertz refresh rate. If a higher refresh rate is a high priority, Razer also has a 1920 x 1080 screen with a whopping 240-Hz rate which is a first for the company. The base model of the notebook sports a 1080p display, but with 144-Hz refresh.Razer Blade 15 Specs and PricingIf you’re interested in a Blade 15, Razer has a good number of options for you to choose from. The OLED version of the system falls under the Razer Advanced Model series. It costs $3,299 and features a 2.6-GHz Intel Core i7-9750H processor with 16GB of RAM, storage up to a 512GB NVMe PCIe SSD and up to an Nvidia GeForce RTX 2080 Max-Q GPU. The $2,399 version gets you the 1080p screen with 240-Hz refresh rate while the $1,999 base model buys you a full RTX 2060 GPU, a 512GB NVMe PCIe SSD with an empty slot for a 2.5-inch SATA drive.As far ports, the Advanced Models will feature 3 USB 3.2 Gen 2 Type-A ports, Thunderbolt 3, HDMI 2.08 and a mini DisplayPort 1.4. These higher-tier systems will also feature individual per-key lighting customization, a Windows Hello-compliant IR camera. The laptops are also outfitted with an Intel Wi-Fi 6 AX200 WLAN card, which at up to speeds 2.4 gigabytes per second should translate into faster downloads, game loads and online connections. The base model has single zone lighting, a 720p webcam, 3 Gen 1 USB Type-A ports, Thunderbolt 3, Gigabit Ethernet, HDMI 2.08 and a mini DisplayPort 1.4.Bottom LineAs per usual, Razer has managed to squeeze quite a few goodies into a relatively small space. The 4K OLED display is a show-stopping game changer as is the addition of Intel’s 9th-gen processors. The company also managed to do a bit of futureproofing with the next-gen USB ports and HDMi. I’m definitely excited to get these systems in for testing to see how they stack up to the competition. But it’s definitely an exciting time for PC gaming aficionados in the market for a new laptop.Best RTX 2080 Gaming Laptops (So Far) by Taboolaby TaboolaSponsored LinksSponsored LinksPromoted LinksPromoted LinksYou May LikeKelley Blue Book5 Mid-engine Corvettes That Weren’tKelley Blue BookUndoCNN International for ANAWhy Tennis Pundits Are Tipping This WomanCNN International for ANAUndoMayo ClinicManaging psoriatic arthritis painMayo ClinicUndoForbes.comLebron’s Home Made This Forbes ListForbes.comUndoVerizon WirelessThis new phone will blow your mind.Verizon WirelessUndoTODAYPolice Identify Girl Licking Ice Cream Tub In Viral VideoTODAYUndoAdvertisementlast_img read more
