Both the App Store and Google Play brim with Twitter clients vying for your 140-character affections. We cut through the noise to bring you the best apps for unleashing tweets on the go. A smartphone is the perfect Twitter launchpad. Short and sweet by design, shooting off a tweet from a mobile gadget is a breeze – if you’re using the right app, that is. Twitter’s bite-sized updates are the ideal social content to digest in the short spans of time that life tosses our way when we’re not tethered to a computer, whether it’s on a bus ride or waiting in line for a latte.To reflect the social network’s fast-paced micro-blogging nature, the ideal Twitter app needs to be quick and lightweight without sacrificing the kind of tools that power users crave. Pour too many features into the mix and “full featured” can turn into a nightmare. Happily, there are plenty of good Twitter apps out there, once you sort the wheat from the chaff.Our Choice for iOS: TweetbotThis iPhone exclusive has quite a loyal following, and for good reason. Tweetbot is a great little mobile tweeting toolkit that’s easy to use without shaving off bells and whistles like muting, which can prove invaluable for the everyday Twitter-goer. Tweetbot supports most anything you’d want to plug into it too. You can zap a choice tweet right to Pocket or Instapaper to read the link later, for example. A Web Developer’s New Best Friend is the AI Wai… Tweetbot’s multiple timelines are a must for anyone leaning toward the power-user end of the scale, since they let you hop between accounts and lists effortlessly. Top that off with a gorgeous, responsive UI and a strangely addictive set of sound effects (seriously, I don’t know what it is about the refresh noise), and you’ve got the most well-rounded Twitter app in the iOS stable.The app will set you back $2.99, but that’s a small price to pay for its uniquely successful blend of power and elegance. Cruising your tweets from an iPad? Tweetbot has a pretty slick iPad app to boot.Our Choice on Android: Plume The Android ecosystem lacks a standout as obvious as Tweetbot, but that’s not a bad thing. Google’s mobile OS is all about options, and it offers plenty of fine Twitter clients to choose from. That said, we prefer Plume by LevelUp, creator of Beautiful Widgets, a longtime Google Play all-star. Plume is the latest evolution of an app we used to know as Touiteur, which was solid in its own right. Android’s Twitter clients aren’t always the best-looking apps on the platform (popular client Twicca is a bit of a pixelated eyesore, for example), but Plume manages to include plenty of customization without clutter. You can swipe easily between your timeline, mentions, and direct messages, and painlessly add a column for a custom list or search. Plume also includes mobile must-haves like URL shortening, multiple account support, picture previewing, and a nicely implemented mute tool – a requisite for quieting down folks in your timeline who tend to live-tweet when they get excited about a sports match or TV premiere.The free version is ad-supported, so if the banner at the bottom bugs you, spring for Plume Premium ($4.99).Alternatives for iOS and Android Not too keen on our feature-rich picks? The good news is that the official Twitter app is a solid choice on both the iPhone and Android. While third-party apps are king when it comes to plenty of social services, Twitter’s official app is one of the best of the lot. It lacks some of the tools that true Twitter addicts require, but it’s reliable, good-looking and intuitive. Ultimately the best Twitter client (or any client, really) is the one that speaks to your needs specifically, but if you want a fallback, you’ll be well-served by the official app.Still not quite the right fit? Beyond regular ol’ Twitter and our main picks, check out Twitterific and Echofon for iOS and UberSocial or Seesmic on Android. Finding the right app for zapping your 140-character flashes of brilliance is serious business, after all. 8 Best WordPress Hosting Solutions on the Market Why Tech Companies Need Simpler Terms of Servic… Related Posts taylor hatmaker Top Reasons to Go With Managed WordPress Hosting Tags:#apps#web

By Dr. Liji Thomas, MDJul 15 2019A new study reported in Nature Communications has discovered activators for molecules that act as motors to move materials around within nerve cells.Nerve cells form the basis of the nervous system in animals, as they transfer information between the various sensory and effector organs of the body and the brain and spinal cord. However, this function relies heavily on the transport of several proteins and other molecules between various parts of the cell.A nerve cell comprises a cell body, and multiple short branches called dendrites. It also has a long projection called the axon which carries signals away from the neuron. Nerve cells also have tiny tubular tracks composed of microtubules along which cargo is moved to and from the dendrites and axons by an attached molecular motor called KIF1C.Human cells synthesize many types of motor molecules, called kinesins and dyneins. These carry cargo towards opposite ends of the cell, and both motors are often present on cargoes so that they can change direction if their progress is hindered. However, there is still a vast field for research into the regulation of KIF1C in both space and time within cells, to allow its application in a host of neurological disorders. Researcher Anne Straube says, “If we understand how motors are shut off and on, we may be able to design cellular transport machines with altered properties. These could potentially be transferred into patients with defect cellular transport to compensate for the defects. Alternatively they can be used for nanotechnology to build new materials by exploiting their ability to concentrate enzymes or chemical reagents. We are also studying the properties of the motors with patient mutations to understand why they function less well.” There are 45 kinesins, but only a few of them are actually understood, in terms of what sets the motors in action. Among them, KIF1C is the fastest motor in nerve cells, and is used for various processes within the neuron that require cargo transport in either direction. Defects in this motor underlie several debilitating nerve disorders, including hereditary spastic paraplegia, that is known to affect about 135,000 people the world over. Alzheimer’s disease and dementia are other conditions which are also linked to poorly functioning molecular motors.KIF1C is a typical molecular motor, a protein which acts as a chemical-to-mechanical energy converter. This helps it to carry diverse loads in dense core vesicles within the cell. KIF1C also transports molecules called integrins that are important for cell adhesions.Related StoriesNanoparticles used to deliver CRISPR gene editing tools into the cellNeural pathways explain the relationship between imagination and willingness to helpPosterior parietal cortex plays crucial role in making decisions, research showsKIF1C must remain at rest while the loading process is underway, and move the cargo once loading is complete until it is actually offloaded at the end of the trip. When compared to motor size, nerve cells are incredibly long, up to 3 feet. The transport system must be foolproof at the same time to avoid inhibition of nerve function.The current study at the University of Warwick was aimed at unraveling the mechanism of activation/inactivation of KIF1C. The scientists found that the inactive state of the KIF1C molecular motor is related to its autoinhibition, caused by the infolding of the molecule on itself. This causes its stalk to link to the part that attaches to the microtubules forming the tracks, and so keeps it out of action.When its function is required, it utilizes two other proteins on the cargo, called PTNPN21 and Hook3. Either of these proteins attaches to the stalk of the KIF1C molecule, which results in its unfolding and activation. The outcome is that it slots into the tracks and starts to run along them, rather like a marathoner beginning the race at the starter’s gun.When these proteins are present, they increase the rate at which the KIF1C lands on the tracks by about 40%. Thus the cargo is able to activate the KIF1C motor when loaded. This may be one way in which kinesins can transport cargo both ways without contradictory pulls. When these proteins are present, they can rescue the function of cells that lack adequate KIF1C expression.If this discovery is confirmed, it could be used to start up or increase motor activity to shift required cargo within neurons to normalize the functioning in KIF1C-depleted nerve cell disorders. The team is currently considering work on hereditary spastic paraplegia. Intracellular transport, kinesin motor proteins transport molecules moving across microtubules, 3D illustration.

Economists have previously made little use of high-performance computers (HPC) in their research. This is despite the fact that the complex interactions and heterogeneity of their models can quickly cause them to reach hundreds of dimensions, which cannot be calculated using conventional methods. In the past, simplified models were therefore often formulated for answering complex questions. These models solved some problems, but they could also provide false predictions, explains Simon Scheidegger, Senior Assistant at the University of Zurich’s Department of Banking and Finance. For example, quantitatively studying optimal monetary policy in the wake of a financial crisis cannot be properly achieved using the conventional methods. However, calculating high-dimensional models on a supercomputer is not easy either. Until recently, researchers lacked appropriate numerical analysis and highly efficient software. Bayesian model selection shows extremely polarized behavior when the models are wrong Explore further More information: More Information: www.pasc-ch.org/projects/solid … -agent-macro-models/ Aryan Eftekhari et al.

DOI: 10.1145/3093172.3093234 Provided by Swiss National Supercomputing Centre Citation: Economists cash in on efficient, high-performance computing method (2018, February 22) retrieved 18 July 2019 from https://phys.org/news/2018-02-economists-cash-efficient-high-performance-method.html The curse of dimensionalityUnlike in physics models, in which time is considered as a fourth dimension alongside the three spatial dimensions, economic models have to consider ten- or even a hundred-times more dimensions. Even a “simple” model of pension insurance in a single country, which aims to depict the prosperity of its society at each year of age, clearly shows how quickly a higher dimensionality is reached: “If we assume that people will live to 80 years old on average and will be earning from the age of 20, and want to determine prosperity for each year of age, we already have 60 dimensions,” explains Scheidegger. What’s more, people make their current decisions while taking into account future uncertainties. Ideally, a model should consider all these influences.There are two main sticking points in calculating such complex economic models. The first is recursively approximating the high-dimensional functions using many iteration steps. At the same time, systems of non-linear equations must be solved at millions of grid points that describe the model. Calculating such a model can take hours and sometimes days of computing time, even on high-performance supercomputers like Piz Daint.Nested modelTo find a highly efficient solution method that can recursively calculate the economic decision-making rules (known as policy functions), the researchers combined so-called sparse grids with a high-dimensional model reduction framework. “The resulting linear combination of sparse grids, which describe the model and thus the policy functions, are nested together like a Russian doll, and are lined up in such a way that they optimally approximate and describe the original high-dimensional space,” explains Scheidegger. The beauty of it is that the code to calculate the individual grids and their combination is highly parallelised. Even in small models with “only” 50 dimensions, the method efficiently scales up on Piz Daint to as many as 1,000 computer nodes at the same time. In simple terms, the dimensional decomposition framework ensures that only the relevant grid points and dimensions that describe the model under consideration need to be calculated. To further minimise the time required to solve the functions and keep communication between the processors and the processes running on them highly efficient, the researchers also used a hybrid parallelisation scheme (message passing interface (MPI) and Intel(R) threading building blocks (TBB)).Scheidegger and his colleagues have thus developed a method that takes significant account of the heterogeneities and avoids oversimplification. It also works generically and so can be applied to a variety of issues-from public finance models, such as state pensions, to central bank models. “As is the case in computer-aided physics or chemistry, the new method should enable models in economics to be solved fundamentally, that is ab initio, and then confronted with real-world data and adapted as necessary,” says Scheidegger.Further research on this topic will be conducted in a project for the Platform for Advanced Scientific Computing (PASC).

Citation: Insect behavior, miniature blimps may unlock the key to military swarming technology (2019, May 15) retrieved 17 July 2019 from https://phys.org/news/2019-05-insect-behavior-miniature-blimps-key.html Don Sofge, lead for the distributed autonomous systems group at NRL, and his team are working to further research for autonomous super swarms. Their goal is to fly more than 100 controlled miniature blimps this year.Georgia Tech researchers created the miniature blimp platform and continue to provide design upgrades in collaboration with Sofge’s group. This year, they are upgrading the motors, adding sensors and making design tweaks.”The process is a constant give-and-take with design and scale,” Sofge said. “It’s better to start with a simple design. You start with something that works and then make incremental changes. There are challenges with design and there are challenges with scaling. So we are redesigning and then scaling up to produce the 100 blimps. We are taking it one step at a time.”The Science of SwarmingOne of the goals for Sofge’s research is to understand the potential uses for swarms of autonomous systems—both defensive and offensive. Some desired emergent behaviors include protecting an asset, providing area coverage, conducting reconnaissance missions, or simply moving in formation from one location to another.He likens individual autonomous agents to ants in a colony. Ants perform actions often equated with the functions of a society, but they do not have a central control. The possibility of replicating individual behaviors in autonomous systems is of great interest to researchers.”We are using these as platforms to demonstrate swarm behaviors,” Sofge said. “Behaviors are programmed into each agent individually. The idea is that each agent is making its own decisions, sensing the world around it so that the action of the group results in some desirable emergent behavior.””In order to get the swarm to do something useful, you have to think about how to program the individual,” he said. “What behaviors or algorithms are running on the individual agent? In nature, most colony or swarm systems have no centralized control. Each individual is basically interacting with its environment, but collectively they are able to do very interesting and useful things.” Engineers to Develop Robot Swarms from MARS Credit: Naval Research Laboratory Sofge and his team plan to design such behaviors to scale up emergent swarming behavior to involve as many as 10,000 autonomous systems.”If you are working with a traditional centralized control architecture you have to deal with the challenges of communicating with 10,000 agents individually,” Sofge said. “You can’t assume everyone knows where everyone else is because they are only interacting locally based on what they sense and the decisions they are making and the actions they are taking locally.”The NRL research team is also working to establish a seamless networking architecture. They are leveraging existing network architectures and protocols for large numbers of objects working together. Each object in a swarm is dynamic and its location is never fixed. The object may move in and out of the network, which makes overlaying a network architecture extremely difficult.Autonomous objects in a swarm must deal with a challenge common in military environments: communication. The U.S. Department of Defense operates all over the world, from the chilling Arctic to hot tropical forests. Staying in communication with an agent despite inhospitable environments and potential enemy jamming is something Sofge and his team must keep in mind as they develop swarming technology.The History of Autonomy Imitating LifeThe study of swarming behavior at NRL began in the 1990s and was founded on the concept of physicomimetics, a physics-based approach that models the behavior of charged particles interacting with one another. Later, swarming approaches developed at NRL were biology-inspired by animal swarms, such as bees, ants and birds in nature.”In physicomimetics, you define objects as being particle types and create force laws to describe action between those particle types,” Sofge said. “By choosing your particle type and force laws appropriately you could get swarms of agents to do interesting things, like move in formation and flow around objects.”Using bio-inspired concepts such as quorum sensing, an ability that bacteria use to communicate and coordinate via signaling molecules, Sofge’s team demonstrated complex group decision-making using simple agent-based behaviors.NRL’s researchers have advanced physicomimetics and nature-inspired techniques for teams of autonomous systems and plan to continue to develop new algorithms for swarming behaviors. The most recent findings have advanced swarm technology and show potential for making advances in human-machine interfaces.

Andhra Pradesh June 18, 2019 COMMENT politics national politics SHARE SHARE EMAIL The Andhra Pradesh Assembly and the State Legislative Council unanimously passed resolutions urging the Centre to grant the promised Special Category Status (SCS) to the State while rejecting any special package in lieu of the promised SCS.Moving the resolution, Chief Minister Jaganmohan Reddy said previously the TDP government during its tenure had accepted a special package instead of the promised SCS and even the Assembly had passed a resolution. “To set the record straight, my Government is moving the resolution and urging the Centre to accord SCS to the State, immediately, respecting the wishes and sentiments of the five crore people of Andhra Pradesh and honouring the promise made on the floor of the Rajya Sabha at the time of the bifurcation of the State,” he said.He said the TDP government was responsible for the State not getting the SCS, as it did not pursue the matter in right earnest from the beginning. “In fact, it was a done deal. When the UPA was in power, in March 2014 the Union Cabinet, had sanctioned SCS to Andhra Pradesh and sent the recommendation to the Planning Commission to get it implemented. Even after the NDA government assumed charge in 2014, of which the TDP was also a member, the Planning Commission was in existence till the end of 2014. It was during this period the then Chief Minister, N Chandrababu Naidu, should have exerted pressure on the Planning Commission to secure SCS for the State. Subsequently, the Planning Commission was replaced by the NITI Aayog and the State government had accepted the special package and lost heavily..”Then, several YSR Congress members including ministers criticised the former chief minister for his stand on the matter and at times heckled him.Chandrababu Naidu’s response The former chief minister said, “You are indulging in mud-slinging and distorting facts and blaming me. In all earnestness, we tried to secure the SCS for the State, but the NDA government did not honour the promise given on the floor of the House by former Prime Minister Manmohan Singh. The special package was accepted, as a categorical assurance was given by the then Finance Minister, Arun Jaitley, that all the benefits under the SCS would be included in the package. But subsequently it became clear to us that the NDA government did not intend to honour the promise and we walked out of the Government and the NDA. Even sacrificing the political interests of the TDP, we fought the NDA government and tried to secure the SCS for the State.”Admitting that the TDP had failed to secure the SCS for the State, he said, “We have tried sincerely and failed. Now it is your turn. People have rejected us and given you a massive mandate, 22 members of Lok Sabha from the State belong to your party. We will also support you. Get the SCS for the State. You will gain nothing by abusing me, heckling me and slinging mud on me or my party.”In the State Legislative Council, Deputy Chief Minister P Subhash Chandra Bose moved the resolution for the SCS and it was unanimously passed.Earlier, in AP Assembly K Raghupati of YSR Congress was unanimously elected the Deputy Speaker of the House. The Assembly was adjourned sine die on Tuesday.
