Citation: Botnets move P2P as centrally controlled zombie networks come under fire (2011, April 22) retrieved 18 August 2019 from https://phys.org/news/2011-04-botnets-p2p-centrally-zombie-networks.html Traditionally, botnets have relied on a small group of control computers to send out instructions to thousands of infected PC’s to do their dirty work, despite the fact that is has a very large major weakness; take away the few central computers and the botnet dies. Because of this, another type of botnet, where each bot contains additional code that allows it to pass along instructional information, is starting to emerge. With these so-called P2P networks, no central command is needed, instructions are fed to just one or two members of the network, and those few pass them along to others, who in turn pass them on until the whole network has been updated and is working as one.Clearly this new type of botnet would be a lot harder to kill. Enter researchers from Los Alamos National Laboratories, in New Mexico, where Stephan Eidenbenz and his colleagues have been creating and killing botnets in a secure lab. Recently, they published a paper in Computer Networks describing a modified version of a P2P botnet that they believe would create a significant problem for those looking to stamp out botnets in general. In this new configuration, the bot network would set itself up into a hierarchy with instructions coming only from a computer higher up the in the hierarchy, who would in turn only receive commands from one higher up yet, until the one at the top is reached.Creating such a network would overcome some of the technical difficulties that botnet builders have been running into when trying to create strong stable conventional P2P botnets, and that is, the complications that arise when trying to create a network that relies purely on individual PC’s being able to communicate with one another; that would be sort of like relying on information from word of mouth, or rumor, rather than getting it straight from the top. In the new configuration (wherein the authors clearly don’t disclose the how-to part, as that would give the bad guys the goods) there is once again just a few computers running the show, but the trick is, the hierarchy is scrambled anew each day allowing different computers to sit at the top issuing commands down the line, thus making it virtually impossible for law enforcement to track down which machines are actually issuing the commands at any given point in time.By doing research of this kind, those on the right side of the law are hoping to create the next generation botnets before those on the wrong side figure out how to create them for themselves; and hopefully by that time, ways to kill them. © 2010 PhysOrg.com Explore further Researchers: Botnets Getting Beefier More information: AntBot: Anti-pollution peer-to-peer botnets, Computer Networks, doi:10.1016/j.comnet.2011.02.006AbstractBotnets have emerged as one of the most severe cyber-threats in recent years. To evade detection and improve resistance against countermeasures, botnets have evolved from the first generation that relies on IRC chat channels to deliver commands to the current generation that uses highly resilient P2P (peer-to-peer) protocols to spread their C&C (Command and Control) information. On an encouraging note, the seminal work done by Holz et al.  showed that P2P botnets, although relieved from the single point of failure that IRC botnets suffer, can be easily disrupted using pollution-based mitigation schemes.For white-hat cyber-security practitioners to be better prepared for potentially destructive P2P botnets, it is necessary for them to understand the strategy space from the attacker’s perspective. Against this backdrop, we analyze a new type of P2P botnets, which we call AntBot, that aims to spread their C&C information to individual bots even though an adversary persistently pollutes keys used by seized bots to search the C&C information. The tree-like structure of AntBot, together with the randomness and redundancy in its design, renders it possible that individual bots, when captured, reveal only limited information. We mathematically analyze the performance of AntBot from the perspectives of reachability, resilience to pollution, and scalability. To evaluate the effectiveness of AntBot against pollution-based mitigation in a practical setting, we develop a distributed high-fidelity P2P botnet simulator that uses the actual implementation code of aMule, a popular Kademlia-based P2P client. The simulator offers us a tool to evaluate the attacker’s strategy in the cyber space without causing ethical or legal issues, which may result from real-world deployment. Using extensive simulation, we demonstrate that AntBot operates resiliently against pollution-based mitigation. We further suggest a few potential defense schemes that could effectively disrupt AntBot operations and also present challenges that researchers need to address when developing these techniques in practice.via Technology Review (PhysOrg.com) — Botnets, those networks of computers infected with bots (little pieces of code that allow a computer to be manipulated from an outside source) have increasingly of late come under attack by law enforcement agencies as it’s become apparent that criminals are using them to steal personal information such as credit card numbers and pins. But, as the centrally based botnets go down, new peer to peer (P2P) botnets are cropping up to replace them.
(PhysOrg.com) — A group of researchers from Carnegie Mellon University in Pittsburgh, have shown that the emissions produced by aircraft idling at the gate, or lining up for takeoff, contain tiny oil droplets, that when exposed to ordinary sunlight, undergo a chemical reaction that causes them to solidify into tiny particles that can infiltrate the lungs and eventually the brain. In a paper published in Atmospheric Chemistry and Physics, the team led by Allen Robinson, describe how they collected samples of exhaust from an idling KC-135 military cargo plane, into large Teflon coated bags, and how they then exposed that exhaust to sunlight and/or UV light to initiate photo-oxidation (when a polymer surface degrades in oxygen or ozone). The result, they say, was that the original droplets of oil were converted into multiple minute solid particles, small enough to penetrate the lungs and brain of people working or living near airports.In contrast, exhaust emissions from airplanes running at speed, such as when in-flight, tend to be mostly comprised of solid particles, which would not be effected by sunlight in the same way, and thus would pose no additional health hazards over what is already known about such types of pollution.The paper highlights the fact that airplane pollution, and specifically the kind produced at airports, is in stark contrast to other types of pollution emitters such as cars and manufacturing plants, in that little to nothing has been done to reduce the amounts spewed into the environment. It also shows that the type of pollution produced at airports is far more hazardous than was previously thought; but, because these findings are so new, it’s likely no research has yet been conducted to ascertain what exactly happens to the human body when these tiny particles are breathed in on a regular basis.The authors also mention in their paper, the folly of studying emissions from aircraft (or presumably any other pollution emitters for that matter) without following up to find out what becomes of such pollutants as they enter the environment and are affected by such forces as UV radiation, temperature, or other substances.

Phys., 11, 4135-4147, 2011 doi:10.5194/acp-11-4135-2011AbstractField experiments were performed to investigate the effects of photo-oxidation on fine particle emissions from an in-use CFM56-2B gas turbine engine mounted on a KC-135 Stratotanker airframe. Emissions were sampled into a portable smog chamber from a rake inlet installed one-meter downstream of the engine exit plane of a parked and chocked aircraft. The chamber was then exposed to sunlight and/or UV lights to initiate photo-oxidation. Separate tests were performed at different engine loads (4, 7, 30, 85 %). Photo-oxidation created substantial secondary particulate matter (PM), greatly exceeding the direct PM emissions at each engine load after an hour or less of aging at typical summertime conditions. After several hours of photo-oxidation, the ratio of secondary-to-primary PM mass was on average 35 ± 4.1, 17 ± 2.5, 60 ± 2.2, and 2.7 ± 1.1 for the 4, 7, 30, and 85 % load experiments, respectively. The composition of secondary PM formed strongly depended on load. At 4 % load, secondary PM was dominated by secondary organic aerosol (SOA). At higher loads, the secondary PM was mainly secondary sulfate. A traditional SOA model that accounts for SOA formation from single-ring aromatics and other volatile organic compounds underpredicts the measured SOA formation by ~60 % at 4 % load and ~40 % at 85 % load. Large amounts of lower-volatiliy organic vapors were measured in the exhaust; they represent a significant pool of SOA precursors that are not included in traditional SOA models. These results underscore the importance of accounting for atmospheric processing when assessing the influence of aircraft emissions on ambient PM levels. Models that do not account for this processing will likely underpredict the contribution of aircraft emissions to local and regional air pollution. © 2010 PhysOrg.com Credit: Magnus Rosendahl, Public-domain-photos.com Bees helping to monitor air quality at German airports
The authors looked at a set of what they call “18,520 ultrafast black swan events” that they uncovered in stock-price movements between 2006 and 2011. A case in point is what occurred on May 6, 2010, when it took just minutes for a spontaneous mix of interactions in cyberspace to generate the Flash Crash, first a plunge, in minutes, and soon after a recovery.The speed in which the rises and falls occur might last no longer than half a second, unapparent to any human who is tracking prices. Johnson says if you blink you miss it. Flash events may happen in milliseconds and have nothing to do with a company’s real value.To examine such incidences and their frequency the authors of the study waded through price logs from over 60 markets collected by Nanex, a Chicago company that sells streaming market data. The data revealed that the ultrafast fracture events were not infrequent but common, totaling 18,520 in the 2006 to 2010 time span. The authors looked for extreme changes in a stock price, which they defined as a change greater than 0.8 per cent, over timescales shorter than 1.5 seconds.The speed in which ultrafast events happen is of concern as human oversight becomes impossible if trades are taking place faster than humans can react. Machine trading today carries computerized trading algorithms that make automated trades in milliseconds and make some experts uncomfortable, in the fear that out-of-control algorithms can cause a crash. Following the May 2010 event, U.S. regulators, as a safety mechanism, upheld circuit breakers designed to stop trading if a stock price makes a sudden large move. Whether or not that is the best solution around, considering the speed in which today’s machine trading can occur, does not convince all market experts. At that level of resolution, one of the study authors said it was troublesome to even observe, leave alone regulate. The authors suggest an early warning system for when the markets are becoming unstable. According to a Wired report, the authors would like to see an approach that might help steer automated markets by introducing “rogue algorithms when herd behaviors appear imminent.”In a recent Q&A interview, Johnson said the “fracture” analogy to real materials is useful in assessing today’s financial markets. “Where we want to head to is the analogy of a trained aircraft engineer, who can pretty much look at the microscopic arrangement of small fractures in an aircraft and judge whether it is safe to continue flying that plane or not. To have this for markets would be an incredibly important step toward understanding, and managing, risk.” More information: Financial black swans driven by ultrafast machine ecology, by Neil Johnson, Guannan Zhao, Eric Hunsader, Jing Meng, Amith Ravindar, Spencer Carran, Brian Tivnan, arXiv:1202.1448v1 [physics.soc-ph] arxiv.org/abs/1202.1448AbstractSociety’s drive toward ever faster socio-technical systems, means that there is an urgent need to understand the threat from ‘black swan’ extreme events that might emerge. On 6 May 2010, it took just five minutes for a spontaneous mix of human and machine interactions in the global trading cyberspace to generate an unprecedented system-wide Flash Crash. However, little is known about what lies ahead in the crucial sub-second regime where humans become unable to respond or intervene sufficiently quickly. Here we analyze a set of 18,520 ultrafast black swan events that we have uncovered in stock-price movements between 2006 and 2011. We provide empirical evidence for, and an accompanying theory of, an abrupt system-wide transition from a mixed human-machine phase to a new all-machine phase characterized by frequent black swan events with ultrafast durations (<650ms for crashes, <950ms for spikes). Our theory quantifies the systemic fluctuations in these two distinct phases in terms of the diversity of the system's internal ecology and the amount of global information being processed. Our finding that the ten most susceptible entities are major international banks, hints at a hidden relationship between these ultrafast 'fractures' and the slow 'breaking' of the global financial system post-2006. More generally, our work provides tools to help predict and mitigate the systemic risk developing in any complex socio-technical system that attempts to operate at, or beyond, the limits of human response times. (PhysOrg.com) -- In the United States, ultrafast trading in financial markets between 2006 and 2011 was the underlying factor for over 18,000 extreme price changes, according to a new study. Neil Johnson, a professor in the physics department of the University of Miami in Coral Gables, one of the authors of the study, thinks that a buildup of such "fractures" can destabilize the market. This study, “Financial Black Swans Driven by Ultrafast Machine Ecology” was submitted to arXiv earlier this month, suggesting the link between extreme-change fractures and market crashes.

(Phys.org) —Santo Fortunato, Associate Professor of Complex Systems at Aalto University in Espoo, Finland has published a Correspondence piece in the journal Nature, outlining what he describes as an increasing time lag between notable work accomplished by scientists and the awarding of a Nobel Prize for what they’ve achieved. A glance at secret process behind Nobel delay Of course another explanation for the time lag might be the nature of scientific discoveries in general—as we learn more it takes more time for new discoveries to prove themselves. On the other hand it could be that committee members feel more comfortable giving awards to people who have maintained strong reputations throughout their career—to avoid embarrassment should a blemish show up on their record after their groundbreaking work.In any case, Fortunato notes that the trend is increasing across all disciplines, and that there is one example already of what he calls the extinction of laureates—Robert Brout who would have been on the stage with François Englert and Peter Higgs last year when they received a shared Physics award for the discovery of the Higgs boson—he’d passed away at the age of 82, two years earlier.

Prior to 1940, for example, just 20 percent of recipients for work in physics had to wait 20 years or more, 15 percent for chemistry and 24 percent for those working in the physiology or medicine fields. In contrast, since 1985, those percentages have grown to 60, 52 and 45 percent. At the rate we’re going, he notes dryly, there will come a day sometime soon when no one will be able to win any of the awards because they would have all died already—prizes are not granted posthumously.No one really knows why the wait for receiving a prize has grown so long. Some suggest it’s because the committees that grant them find more modern work less ground-breaking and thus keep going back in time to find something they see as worthy. Others suggest the opposite is true, that the glut of breakthroughs creates a backlog, forcing committee members to choose people who deserve the award before they grow old and die (similar to the problem found with many sports organizations as induction into various Halls of Fame tend to skew towards older and older players.) In this case, the problem would be that so few people are awarded each year. © 2014 Phys.org Citation: Professor notes wait for Nobel science prizes is growing alarming long (2014, April 10) retrieved 18 August 2019 from https://phys.org/news/2014-04-professor-nobel-science-prizes-alarming.html

Credit: Science Advances, Adapted from: Acc.Chem.Res, doi: 10.1021/ar800124u The past two decades have witnessed an explosive growth in the field of MOFs, with more than 84,185 MOF structures documented in the Cambridge Crystallographic Data Centre. A collection of papers on the synthesis, structure and application of MOFs continues to be published every year. The SBU approach has advanced MOF chemistry as the most significant contributor to the rapid development observed in the field. Many MOF syntheses, investigations and applications are derived from the SBU approach. Now reviewing the field of MOF chemistry for Science Advances, Markus Kalmutzki, Nikita Hankel and Omar M. Yaghi – recently awarded the BBVA Foundation of Frontiers of Knowledge Award in the Basic Sciences category – consider the history of MOFs and their applications that have arisen via the SBU approach. Metal-organic frameworks (MOFs) are a fascinating class of highly porous materials. They are structurally composed of metal ions/clusters and organic linkers for promising functional diversity in a variety of fields. Properties include their unique crystallinity, tunable porosity and structural diversity. The performance of MOFs was highlighted in diverse applications such as gas storage, catalysis sensing and drug delivery. In particular, SBUs play an important role in vapor absorption, as reported with high water absorption. The structural diversity of MOFs depends on SBUs with future work projected for industrial applications including gas absorption and separation, harvesting water from air, bioimaging and therapeutics.By design, polynuclear cluster nodes, also known as SBUs, are able to impart (1) thermodynamic stability via strong covalent bonds and (2) mechanical/architectural stability by strong directional bonds that can lock down the position of metal centers in metal-organic frameworks. This property contrasts with those of unsteady and nondirectional single metal nodes that formed weak bonds to neutral organic donor linkers. The impact of SBU on the structure, chemistry and applications of MOFs. The rich chemical architecture of MOFs is founded on the structural diversity of the SBUs – rendering MOFs mechanically and architecturally stable and thus permanently porous. The chemical nature of SBUs gave rise to the concept of “framework chemistry” – the post synthetic chemical modification of MOFs as the key to extending their applications. Credit: Science Advances, doi: 10.1126/sciadv.aat9180 Journal information: Science Advances Chemical ‘caryatids’ improve the stability of metal-organic frameworks In contrast to the unpredictable method of traditional synthetic organic chemistry where little to no correlation exists between the structure of starting materials and products, greater predictability exists in MOF chemistry, as they are designed with predetermined topologies. In the synthetic process, the chemical building units required to construct the selected net are determined. The structural diversity observed in MOF chemistry originates from a wide variety of available SBU geometries; specific structures can be designed by choosing appropriately shaped and sized building units. The authors then detailed diverse methods of MOF synthesis, their complexity, chemical frameworks and applications that originated from secondary building units during MOF development. In practice, MOFs can be used for gas storage and separation with specific implications to separate carbon dioxide and other greenhouse gases for environmental sustainability. Metal organic frameworks can also form versatile heterogenous catalysts for efficient organic transformations, be used as luminescent sensors and in drug cargo delivery for cancer therapy. Applications in diverse fields were enabled by the porosity inherent to MOFs, made possible by the SBU approach. The chemical nature inherent to MOFs and SBUs that led to the development of the properties of adsorption, separation and catalysis were then dissected further within the review. The accessibility of pore space within open framework structures enabled the applications observed for MOFs in different fields. The basis for MOFs is related to the ability to manipulate matter with a precision previously only known in well-established molecular chemistry. The crystallinity and porosity of the framework was fully preserved during construction, leading to the development of “crystals as molecules.” Introduction of the SBU approach was a turning point that enabled the extension of precision chemistry from molecular complexes and polymers into 2-D and 3-D frameworks, to design rational structures using functional building units. Recent advances in the field of MOF synthesis confirm the potential to translate properties of functional building units into a structural framework. Such properties include linear and nonlinear optical character, magnetism, conductivity and catalysis. Recent advances in computational chemistry can also help understand material properties and predict structures that can be constructed with the targeted character.Complexity and heterogeneity can be integrated within MOFs as recently proposed, to explore and analyze their impact on the structure and in the resulting properties, in the future. Both complexity and heterogeneity allow to further expand the scope of structures, providing access to materials with great potential for increased performance. Controlling the spatial distribution of different organic functionalities and metal ions can lead to design sequences within or along the MOF backbone. Expected spatial arrangements can be achieved by integrating multiple SBUs with specific binding patterns directly into framework formation for a single material, or via post-synthetic methods. The realization of this vision can give rise to sequence-specific materials designed into MOFs to carry out intended functions. Introduction of the SBU marks a turning point in the development of MOF chemistry – and will continue to play a key role in their future development to access novel structures, properties and applications. © 2018 Phys.org Citation: Secondary building units (SBUs)—the turning point in the development of metal-organic frameworks (MOFs) (2018, October 22) retrieved 18 August 2019 from https://phys.org/news/2018-10-secondary-sbusthe-metal-organic-frameworks-mofs.html There is an urgent need to control materials on the molecular level to make “materials on demand.” A strategy to develop such materials is in development in reticular chemistry, derived from the Latin translation “reticulum” as “having the form of a net.” The strategy links discrete building units (molecules and clusters) via bonds to make large and extended crystalline structures. Metal-organic frameworks (MOFs) are the most prominent class of materials in the realm of reticular chemistry. Such crystalline, extended structures are constructed by stitching together inorganic polynuclear clusters known as secondary building units (SBUs) and organic linkers via strong bonds.
L dwarfs are variable in many ways, including periodic modulation due to clouds, radio emission due to aurora, or the presence of white-light flares. In general, white-light emission occurs through reconnection events in the stellar magnetic field, what results in heating of the lower chromosphere. Although white-light flares are regularly reported on various types of stars, they are rarely observed on L dwarfs. Notably, such events observed on L dwarfs exhibit some of the largest changes in brightness ever recorded. However, finding new white-light flares on L dwarfs is challenging as it requires long-duration observations, in particular high cadence wide-field observations targeting very faint objects.A team of astronomers led by James A. G. Jackman of University of Warwick, UK, has conducted such observations using the Next Generation Transit Survey (NGTS). The observational campaign, aimed at searching for stellar flares on low-mass stars, resulted in the detection of a white-light superflare from ULAS J224940.13-011236.9 (or ULAS J2249-0112) on August 13, 2017. The object on which this flare was spotted is an ultracool L2.5 dwarf with an effective temperature of 1,930 degrees K, about 10 times smaller than our sun, located some 248 light years away from the Earth.”In this letter, we present the detection of a white-light superflare from the L2.5 dwarf ULAS J224940.13-011236.9, which was observed at high cadence with the Next Generation Transit Survey (NGTS),” the researchers wrote in the paper. NGTS observations show that the flare on ULAS J2249-0112 lasted about nine and a half minutes, with a rise time of 12 seconds. The flare had an amplitude of -10 mag, a luminosity of 530 octillion erg/s and an energy of 2.3 decillion erg.The astronomers note that the newly observed flare is the second-largest flare detected from an L dwarf, and the second to be spotted from the ground. Moreover, ULAS J2249-0112 turns out to be the coolest star ever found to exhibit a white-light flare and the sixth L dwarf to have exhibited flaring activity.”With a spectral type of L2.5 we believe ULAS J2249-0112 is the coolest star to show a white-light flare to date,” the scientists noted.According to the authors, the detection of such a large flare on ULAS J2249-0112 illustrates the importance of high-cadence observations with NGTS in studying the largest stellar flares from the coolest stars. “This behavior would not be visible in the TESS [NASA’s Transiting Exoplanet Survey Satellite] 30-minute cadence full-frame images, nor in all-sky surveys, which monitor large areas of sky each night. This shows how NGTS is in an ideal position to probe flare behavior on the latest spectral types,” the researchers concluded. This document is subject to copyright.

Like rivers that cascade fearlessly through landscapes that belong to different countries, like winds that blow incessantly over barbed wires, birds fly and nestle boundlessly. Borders have been built through water-bodies, fields and even houses by humans, and they are for humans. Goutam Ghose’s National Award winning Best Bengali Film Shankhachil is a poignant tale that portrays the plight of a family in crisis. Muntasir Badal Choudhury is a reputed teacher in a village close to the border in Bangladesh. He lives with his wife Laila, and their world revolves around their daughter Rupsha who is the apple of their eyes. Also Read – ‘Playing Jojo was emotionally exhausting’He often stands on the riverbank wrapping his arm around his beloved daughter, narrating to her how unstoppable the flow of the river is. Their life is peaceful until one day they realise the border isn’t just a mere geographical reminder of the partition. The story starts rolling when they come to Kolkata for their ailing daughter’s treatment, and takes a sordid turn with the miseries the couple faces. Shankhachil, a species of kite, is symbolic in the film. The name metaphorically exhibits the freedom of a bird that flies across borders, no nationality to bind it to one land. Only if humans could be kites, their wings spread against the azure sky, strengthening them to soar high above the border wires to distant lands they don’t need to know the names of!
