Researchers Build Artificial Immune System to Solve Computational Problems

first_img Citation: Researchers Build Artificial Immune System to Solve Computational Problems (2009, December 3) retrieved 18 August 2019 from https://phys.org/news/2009-12-artificial-immune-problems.html (PhysOrg.com) — By mimicking the way that a living body acquires immunity to disease through vaccination, researchers have designed an artificial immune system to solve optimization problems more effectively than before. The results show that the biologically motivated approach is better at exploring a greater amount of space and quickly locating the desired local and global optima than previous methods. The researchers, Kumlachew M. Woldemariam and Gary G. Yen, both from Oklahoma State University, have published their study in a recent issue of IEEE Transactions on Systems, Man, and Cybernetics – Part B: Cybernetics. As the researchers explain, the field of artificial immune systems (AIS) is an emerging branch of evolutionary computation in which computational systems are based on the structure and behavior of the immune system. By providing methods in pattern recognition, data analysis, and machine learning, AIS has applications in fields including computer science, robotics, and information technology.Unlike previous artificial immune systems, the system in the new study specifically takes advantage of the way that vaccines can improve the performance of the immune system. The antibody cells in the immune system are constantly trying to recognize foreign or malfunctioning cells (antigens such as bacteria, viruses, and tumors) in the midst of the body’s own healthy cells (mainly other antibodies). The way that the immune system distinguishes between different kinds of cells can be formulated as an optimization problem, in which the antibodies are the points in the decision space and the antigens are the solutions that the immune system looks for.Although the immune system usually works very well, sometimes it doesn’t identify an antigen quickly enough to prohibit it from causing illness. To accelerate the immune system’s functioning, vaccines can be administered to enable the immune system to detect a new (weakened) antigen and develop an immunological memory so that it can quickly recognize the same antigen in the future. Drawing inspiration from how such vaccines work, the researchers’ artificial immune system can be enhanced to quickly identify optimum solutions by being injected with certain points in decision space that act as weak antigens, or vaccines. In their study, Woldemariam and Yen explain how to determine which points should be used as vaccines to be “injected” into the algorithm. Once in the algorithm, the vaccines activate the antibody population to incorporate more diverse antibodies and explore new landscapes in decision space, so that the antibodies continually come closer to locating a desired local optimum point. “The main idea of introducing the notion of vaccines in the evolutionary algorithm is to help enhance the diversity of antibodies,” Yen told PhysOrg.com. “The way the vaccines are extracted from the decision space is in such a way that the decision space is explored widely. The implementation of the algorithm in multimodal optimization problem shows how fast and efficiently the antibodies, triggered by the vaccines, learn and locate the local and global optimal solutions of the problem. Therefore the vaccines help antibodies to achieve a speedy learning and diversified exploration.”When comparing the new algorithm, called Vaccine-AIS, to other artificial immune systems, the researchers found that Vaccine-AIS outperformed the others by locating the global and local optima in a plot in fewer evaluations. The key to the improved performance is that the algorithm can cover a larger portion of the search space, due to help from the vaccines. As Yen added, AIS has the potential for improving computational abilities in many other areas.“AIS was originally designed for data mining, anomaly detection and the like,” Yen said. “Its use as an optimization tool is a very young research area but its performance is drawing interest from researchers. Recently there has been research on using artificial immune systems in fault estimation and to design a power system stabilizer. The application of AIS in medical image processing for MRI (magnetic resonance imaging) is being studied as well.”More information: Kumlachew M. Woldemariam and Gary G.

Physicists offer countermeasure to new quantum eavesdropping attack

first_img Quantum eavesdropper steals quantum keys In the attack, Eve sends light pulses of one of four polarizations (horizontal, vertical, +45°, or -45°) to blind three of Bob’s four detectors, each of which can detect one type of polarization. If a detection event occurs, then Eve knows it had to have happened in the detector that can detect the polarization opposite from that which she used. For example, if she sends out pulses with vertical polarization, the detectors corresponding to vertical, +45°, and -45° will see the light, while the horizontal detector won’t. So all detectors except the horizontal one are blind. If a click occurs in Bob’s following time window, it can only have happened in the horizontal detector. In this way, Eve can gain information about the key bits being sent to Bob’s detectors. By tuning the intensity of the blinding pulses, Eve can tune information about the key. In experiments, the scientists demonstrated that dim pulses containing only a few photons can determine almost all of the key (in this case, the emblem of the University of Munich). On average, an eavesdropper needs fewer than 20 photons per binding pulse to gather over 98% of the key information. Since the error between Alice and Bob does not increase during the attack, they are not aware of the eavesdropper’s presence.As simple as this attack is, the scientists explain that a defense against it is even simpler. Bob could monitor the status of his single-photon detectors to ensure that the detection efficiency has not been compromised. When generating their shared key, Alice and Bob would only use detection events in which all detectors were active. So even if Eve had been blinding Bob’s detectors and intercepting the key bits, those bits would not end up being used, and the attack would fail.“In my opinion, actual systems can generally never be proven to be secure,” Weier told PhysOrg.com. “In this respect, QKD isn’t better than its classical counterpart. But scientists are working on bridging the gap between theoretic models and real systems. Ideally one can build a provably secure model that describes the actual QKD system including all (known) implementation imperfections. If the theoretic model gave some bounds with regard to the imperfections, one would get as close to perfect security as possible.” Citation: Physicists offer countermeasure to new quantum eavesdropping attack (2011, July 25) retrieved 18 August 2019 from https://phys.org/news/2011-07-physicists-countermeasure-quantum-eavesdropping.html Using the “dead time” attack, Eve can recover Alice and Bob’s secret key, the emblem of the University of Munich, without being detected.

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. (PhysOrg.com) — As early communications systems using quantum cryptography become commercially available, physicists have been investigating new types of security attacks in an effort to defend against them. In a recent study, researchers have identified and demonstrated a new, highly effective way to eavesdrop on a quantum key distribution (QKD) system that involves blinding the receiver’s detector during the “dead time” of single-photon detectors. For the first time, the eavesdropper does not even have to intercept the quantum channel to compromise the system’s security, making this attack technologically very simple. The physicists, Henning Weier from the Ludwig Maximillians University of Munich and Qutools GmbH in Munich, and coauthors, have published their study on the new quantum eavesdropping attack, along with a countermeasure to prevent it, in a recent issue of the New Journal of Physics.In QKD systems, two communicating users (Alice and Bob) produce a secret key of qubits, and then use that key to encrypt and decrypt messages. If an eavesdropper (Eve) can uncover this key without being caught, she too can decrypt the messages.As the physicists explain, theoretical proofs have shown that the ideal QKD protocol is completely secure; that is, the amount of information that an eavesdropper can steal can be quantified and made negligibly small. If Eve were to attack the system, Alice and Bob could detect her presence due to the high error rate, and no secure key will be made. However, when QKD systems are implemented in practice, they can be vulnerable to certain types of attacks, depending on the hardware used.The attack described here could be used to intercept the key as Alice and Bob are creating it together. This scheme and similar ones work in almost any QKD system since they exploit a feature common to almost all single-photon detectors, which is the dead time. After a detection event, single-photon detectors are rendered inactive for a period of time that can range from less than a nanosecond to a few tens of microseconds. During this dead time, detectors cannot detect incoming photons.Taking advantage of this dead time, Eve can send light pulses into the quantum channel to partially blind Bob’s (the receiver’s) photon detectors. Timing these pulses is critical, since they must be sent shortly before Bob’s “time window.” As the scientists explained, Bob knows roughly when the photons from Alice should arrive, and accounts for only those photons that come during a narrow time interval around the expected arrival time. The time window allows Bob to filter out background photons (especially during the day) and reduce the error rate significantly. In this case, however, Eve can take advantage of this time window to prevent Bob from noticing her pulses.last_img read more

Researcher finds missing link between ancient toothed whales and modern baleen whales

first_imgEvolution of mysticete skull features linked to feeding, based on the phylogeny in the study of Fitzgerald. Cetacean artwork by C. Buell. Image (c) Biology Letters, doi:10.1098/rsbl.2011.0690 More information: Archaeocete-like jaws in a baleen whale, Biology Letters, Published online before print August 17, 2011, doi:10.1098/rsbl.2011.0690AbstractThe titanic baleen whales (Cetacea, Mysticeti) have a bizarre skull morphology, including an elastic mandibular symphysis, which permits dynamic oral cavity expansion during bulk feeding. How this key innovation evolved from the sutured symphysis of archaeocetes has remained unclear. Now, mandibles of the Oligocene toothed mysticete Janjucetus hunderi show that basal mysticetes had an archaeocete-like sutured symphysis. This archaic morphology was paired with a wide rostrum typical of later-diverging baleen whales. This demonstrates that increased oral capacity via rostral widening preceded the evolution of mandibular innovations for filter feeding. Thus, the initial evolution of the mysticetes’ unique cranial form and huge mouths was perhaps not linked to filtering plankton, but to enhancing suction feeding on individual prey. Citation: Researcher finds missing link between ancient toothed whales and modern baleen whales (2011, August 18) retrieved 18 August 2019 from https://phys.org/news/2011-08-link-ancient-toothed-whales-modern.html Explore further © 2011 PhysOrg.com (PhysOrg.com) — Erich Fitzgerald, an Australian paleontologist, believes he has found the missing link between ancient toothed whales that caught and ate fish and modern baleen whales that eat by sucking in huge volumes of water and then filter out the krill and shrimp in it. Australian fossil unlocks secrets to the origin of whales This document is subject to copyright. 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. In his paper, published in the Royal Society journal, Biology Letters, Fitzgerald describes the skeletal remains of Janjucetus hunderi, named for the beach where the original jaw bone was found; “cetus” Greek, for whale and Staumm Hunder, the youngster who found the fragment. More recently, Fitzgerald discovered that amateur fossil hunter Brian Crichton had more such bones enabling him to build a more complete picture of the ancient (25 million year old) creature.Fitzgerald suggests that modern baleen whales, a class of whales that use a filter called a baleen to filter food from sea water, evolved from toothed fish eaters to the modern giants we now see, via the Janjucetus, a creature about the size of a contemporary dolphin, but one that had a very different jaw structure.Baleen whales, a class that include the Blue Whale, the largest animal known to have ever existed, have a jaw that is not fused in front, allowing it to flex and expand so that it can draw in huge amounts of water when lunging at a mass of krill. Ancient whales on the other hand, had jaws very much like dolphins, or even humans for that matter. They opened their mouths and grabbed fish swimming by, using their teeth as mini harpoons, much as Killer Whales do today. Janjucetus falls somewhere in-between; it has a jaw that is fused in front but the upper jaws are inordinately wide, and its snout is short. Also, its mouth is proportionately big for its body. Fitzgerald theorizes that all of these characteristics put together indicate that Janjucetus captured and ate its prey differently than both its early ancestors and its modern counterpart. Instead of grabbing fish as they came by, Janjucetus sucked in the water surrounding them, pulling them in with it, then chomped down to capture them.It’s this early sucking, or “hovering” as Fitzgerald describes it, that after several million years, led to the un-fusing of the jaw, the gradual loss of teeth and the appearance of the baleen.last_img read more

Microbes surviving deep inside oceanic crust

first_img Journal information: Science The paper, published in Science, reports on the analyses of samples of oceanic crust collected during a 2004 expedition to 100 kilometers off the Juan de Fuca Ridge off the coast of Washington state in the U.S..The oceanic crust is a layer of volcanic rock several kilometers thick and covered by thick layers of sediments. Oceanic rock covers around 60 percent of the Earth’s surface and is therefore potentially the largest biosphere on the planet. Microorganisms have been discovered on exposed surfaces of the oceanic crust and in the sediments above it, but the new study is the first to reveal that microbes also live deep within the crust.Mark A. Lever, of the Department of BioScience at Aarhus University in Denmark and an international team of microbiologists drilled through the sea-bottom sediment and deep into the oceanic crust beneath to collect samples for various tests. The sediment depth at the drilling site was about 260 meters thick, and the team collected samples from about 350 to 580 meters deep into the basalt rock beneath, in a region known as the “dark biosphere.” The age of the rock was estimated at 3.5 million yearsThe team ensured all their equipment was sterile to ensure the rock samples were uncontaminated. They also added marker chemicals to the fluid used in drilling, and later confirmed that while these chemicals were found on the rock sample surfaces, almost none found their way inside the rocks. They sterilized the outer surfaces before breaking the rock samples open.The researchers found microbe genes within the rock samples, and to determine if the genes were from living microorganisms or extinct species, they incubated the samples at 65 degrees C (the temperature of the location at which they were found) in water similar chemically to that in their native location, which is rich in chemicals but poor in oxygen. After two years (enough for the slow-growing microorganisms to re-establish themselves) they transferred samples to another container containing sterilized rocks and the same water. They incubated these samples for a further five years.The incubated samples began to produce methane and the carbon-13 concentration reduced, which showed that the microbes in the rock were alive. The scientists concluded the organisms were most likely deriving energy from chemical reactions taking place in the interfaces between the iron-laden rock and water. The chemical reactions produce hydrogen, which the microorganisms use to produce organic matter. Other microbes were identified, which survived by consuming sulfur. These processes of energy production are known as chemosynthesis.The findings suggest that the ecosystems in the oceanic crust are fundamentally different from other ecosystems in that their energy is derived ultimately from chemosynthesis rather than photosynthesis, which derives energy from light.Chemosynthesis is also known to be used by life forms in habitats such as deep boreholes or hydrothermal vents on the fringes of continental plates. The new study suggests that chemosynthesis is possibly more important than photosynthesis in terms of the biomass involved in the processes, depending on how extensive these sort of ecosystems are. Lever also said it is “quite likely there is similar life on other planets.”Dr Lever and his team expect to analyze other samples collected from ocean crusts beneath the North Atlantic and other locations in the Pacific Ocean.

Goblet tricks suggests ancient Romans were first to use nanotechnology

first_img This document is subject to copyright. 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. (Phys.org) —Recent evidence suggests that the Roman craftsmen who created the Lycurgus Cup, a glass drinking goblet, used nanotechnology to cause the goblet to change color under different lighting. The cup’s unique properties were first noted when it was brought to a museum in the 1950s—it wasn’t until 1990, however, that researchers figured out how the color changers were brought about. Citation: Goblet tricks suggests ancient Romans were first to use nanotechnology (2013, August 27) retrieved 18 August 2019 from https://phys.org/news/2013-08-goblet-ancient-romans-nanotechnology.html The goblet was created approximately 1,600 years ago, using a process whereby very tiny gold and silver particles were embedded in the glass. In normal lighting, the glass appears to have a jade background. When lit from behind, however, the green parts suddenly look ruby red. This is all courtesy of the way electrons vibrate when struck by photons—something the Romans could not have known. Yet, because other goblet pieces have been found with the very same mixture, it’s clear they knew they were on to something. They actually used the color changing effects to create stories. The Lycurgus Cup, for example, depicts the story of King Lycurgus as he is caught up in a tangle of grapevines—penance for treachery committed against Dionysus, the god of wine in Greek mythology.Researchers speculate that the Romans simply ground the metal particles until it would take a thousand of them to match the size of single sand grain, then mixed them in with the hot liquid glass. But that wasn’t the end of the story: the Romans created a goblet such as the Lycurgus Cup, by carving it from a single block. That means they also understood that different thicknesses of the glass would exhibit different coloring as well.New research has suggested that the cup also changes colors when liquid is poured into it (although the researchers did not do so as it might have caused damage). Instead, they undertook lab experiments to replicate the makeup of the cup then applied various liquids. Their results suggest the cup might have displayed a variety of colors depending on which sort of beverage was poured into to it.Researchers are just now, all these years later, learning about such color changing properties of materials with embedded nanoparticles. The hope is that these properties can be exploited to perform chemistry or medical tests cheaply and quickly by displaying different colors under different conditions.
