( — A new analysis of number randomness in Sudoku matrices could lead to the development of more difficult and multi-dimensional Sudoku puzzles. In a recent study, mathematicians have found that the way that numbers are arranged in Sudoku puzzles is even more random than the number arrangements in randomly-generated matrices. The counter-intuitive discovery may enable researchers to develop algorithms that generate Sudoku matrices with fewer clues, making them more difficult to solve.

Toy Robot to Solve Sudoku (w/ Video)center_img — Paul K. Newton and Stephen A. DeSalvo. “The Shannon entropy of Sudoku matrices.” Proceedings of the Royal Society A. doi: 10.1098/rspa.2009.0522.– Via: ABC Science More information: Mathematicians Paul Newton and Stephen DeSalvo of the University of Southern California in Los Angeles have published the results of their study in a recent issue of the Proceedings of the Royal Society A. “I think it will help develop multi-dimensional Sudoku puzzles, and answer questions about how to give the initial [clues] in order to create a hard, but still solvable Sudoku puzzle,” Newton said in an article at ABC Science.Sudoku is a number puzzle consisting of a 9×9 grid, whose 81 boxes are filled in with the numbers 1 through 9 in a way that meets certain criteria. Each number can only appear once per row and once per column, as well as only once in each of the nine 3×3 sub-grids that make up the matrix. In 2006, researchers (Felgenhauer and Jarvis) found that there are about 6.67 x 1021 different Sudoku matrices that satisfy these three criteria. In contrast, the total number of different 9×9 randomly generated matrices is much greater: 981. The ratio of these two numbers, or the probability of randomly generating a Sudoku matrix by randomly selecting each number in each box independently, is very small: about 3 x 10-56. This small probability results from the constraints put on Sudoku matrices.In their study, Newton and DeSalvo wanted to find out how exactly random a Sudoku matrix is, given these constraints. To answer this question, they generated a representative sample of about 10,000 matrices and compared them to randomly generated matrices. They were surprised to find that Sudoku matrices are actually more random than randomly-generated matrices. This result is counterintuitive since you would expect that, the more constraints on a matrix, the less random it will be. Instead, the rules of Sudoku seem to “weed out” matrices with patterns. For example, as Newton explained, a randomly generated matrix could potentially consist of all one number, alternating numbers, or some other pattern not allowed in Sudoku. The imposed high level of number distribution in Sudoku gives it a higher level of entropy, making it more random than random matrices.Newton and DeSalvo predict that this greater understanding of Sudoku could lead to better Sudoku-generating algorithms that create more difficult puzzles. Currently, Sudoku puzzles require at least 17 numbers to be given in their correct boxes in order for the puzzle solver to find a unique solution. The new study could decrease that number, making it more difficult to solve the puzzles. Future algorithms might also develop more complex 3D Sudoku cubes. “I think it will give people a lot of insight into how to produce better algorithms for constructing Sudoku matrices and it will enable ultimately the very fast learning algorithms that solve Sudoku matrices,” Newton said.Australian mathematician Marcel Jackson of Latrobe University in Melbourne, who was not affiliated with the study, added that understanding Sudoku matrices better might also be useful in coding information to minimize the effect of errors in transmission. © 2010 PhysOrg.comlast_img read more

Team says Arctic ice shelf broke up before

first_imgImage: NASA/Goddard Space Flight Center Citation: Team says Arctic ice shelf broke up before (2011, October 25) retrieved 18 August 2019 from Now however, new research by a team from Université Laval in Canada, led by Dermot Antoniadesa, have found, after studying sedimentary material on the bottom of the Disraeli Fiord, created by backup from an ice shelf in Northern Canada, that it experienced a major fracture that resulted in an overall reduction of the ice shelf some 1,400 years ago. Which means this isn’t the first time that the shelf ice has melted and broken apart. The team has published the results of its survey in the Proceedings of the National Academy of Sciences.Shelf ice is a thick platform of ice that has been pushed out to sea by glacier pressure. As the sea level drops, the ice tends to float even as it’s still connected to the shore. Hence its name, it literally looks like a giant shelf hanging off the land out into the sea. One ice shelf in particular, Ward Hunt, located on Ellesmere Island, lies off the north central coast of Canada and is part of a group of ice shelves that once comprised most of the northwest coast of the Island. Over the past hundred years, the shelf ice in this region has diminished by nearly 90%.Because ice shelves also act as dams, backing up water into fjords, sediments from them build up on the sea floor and in the spaces between the salty seawater and fresh water produced by melting ice. By analyzing these sediments using carbon 14 dating and other techniques, the researchers are able to create a record or timeline of sorts that they can use to look into the past. In this case, the research team found that the ice shelf first appeared approximately 4,000 years ago and hung around for several thousand years. But then about 1,400 years ago, a major fracturing occurred that caused the shelf to shrink. It didn’t fully recover until about 800 years ago. After that, it held steady till the shrinkage that began nearly a hundred years ago and continues to this day.At this point, it doesn’t appear that the shelf ice around Ellesmere Island is any smaller now than it was during the previous period of warming, but because it’s still shrinking, it’s possible it could become, as Antoniadesa writes, an “unprecedented” event. © 2011 More information: Holocene dynamics of the Arctic’s largest ice shelf, PNAS, Published online before print October 24, 2011, doi:10.1073/pnas.1106378108AbstractIce shelves in the Arctic lost more than 90% of their total surface area during the 20th century and are continuing to disintegrate rapidly. The significance of these changes, however, is obscured by the poorly constrained ontogeny of Arctic ice shelves. Here we use the sedimentary record behind the largest remaining ice shelf in the Arctic, the Ward Hunt Ice Shelf (Ellesmere Island, Canada), to establish a long-term context in which to evaluate recent ice-shelf deterioration. Multiproxy analysis of sediment cores revealed pronounced biological and geochemical changes in Disraeli Fiord in response to the formation of the Ward Hunt Ice Shelf and its fluctuations through time. Our results show that the ice shelf was absent during the early Holocene and formed 4,000 years ago in response to climate cooling. Paleoecological data then indicate that the Ward Hunt Ice Shelf remained stable for almost three millennia before a major fracturing event that occurred ∼1,400 years ago. After reformation ∼800 years ago, freshwater was a constant feature of Disraeli Fiord until the catastrophic drainage of its epishelf lake in the early 21st century. ‘Webcam’ from Space: Envisat observing Wilkins Ice Shelf ( — Arctic shelf ice has been in the news of late due to its shrinkage over the past few decades that most attribute to global warning. Thus, its levels and seemingly constant calving have become ecological barometers that environmentalists have come to use to show just how fast our planet is heating up.

Repulsive gravity as an alternative to dark energy Part 2 In the

first_img Explore further Dark matter may be an illusion caused by the quantum vacuum Citation: Repulsive gravity as an alternative to dark energy (Part 2: In the quantum vacuum) (2012, February 1) retrieved 18 August 2019 from ( — During the past few years, CERN physicist Dragan Hajdukovic has been investigating what he thinks may be a widely overlooked part of the cosmos: the quantum vacuum. He suggests that the quantum vacuum has a gravitational charge stemming from the gravitational repulsion of virtual particles and antiparticles. Previously, he has theoretically shown that this repulsive gravity can explain several observations, including effects usually attributed to dark matter. Additionally, this additional gravity suggests that we live in a cyclic Universe (with no Big Bang) and may provide insight into the nature of black holes and an estimate of the neutrino mass. In his most recent paper, published in Astrophysics and Space Science, he shows that the quantum vacuum could explain one more observation: the Universe’s accelerating expansion, without the need for dark energy. Interestingly, one significant difference between Hajdukovic’s quantum vacuum model and standard cosmology is that the former predicts that the acceleration is decreasing, while the latter predicts it is increasing. Very different predictions for the fate of the Universe result from these differences.“The series of publications shows that the quantum vacuum, enriched with the hypothesis of the negative gravitational charge for antiparticles, has the potential to explain the observed phenomena in astrophysics and cosmology without invoking dark matter and dark energy and mysterious mechanisms for inflation and matter-antimatter asymmetry,” Hajdukovic said. “If antimatter really has negative gravitational charge (which could be revealed by the AEGIS experiment at CERN), the above papers have started a new scientific revolution. But the papers are important even if antimatter has no negative gravitational charge, because they encourage reconsidering the quantum vacuum as a key for the understanding of the Universe.”In addition to the AEGIS experiment in CERN, which is designed to reveal the gravitational properties of antihydrogen, Hajdukovic said that other experiments are also investigating the gravitational properties of antimatter. For instance, physicists at the University of California, Riverside, have recently begun studying the gravitational properties of positronium (an electron-positron pair).Part 1. Repulsive gravity as an alternative to dark energy (In voids) More information: Dragan Hajdukovic. “Quantum vacuum and virtual gravitational dipoles: the solution to the dark energy problem?” Astrophysics and Space Science. DOI: 10.1007/s10509-012-0992-ycenter_img © 2011 Journal information: Astrophysics and Space Science “The quantum vacuum was predicted theoretically more than 60 years ago,” Hajdukovic told “Today, there is significant experimental evidence that the quantum vacuum exists. I have decided to combine one reality (the quantum vacuum) with one hypothesis (the negative gravitational charge of antiparticles) and to study the consequences. The hypothesis of the gravitational repulsion between matter and antimatter is older than half a century, but before me no one has used it in the combination with the quantum vacuum. … The results are surprising; there is potential to explain [the Universe’s accelerating expansion] in the framework of the quantum vacuum enriched with the gravitational repulsion between matter and antimatter.”According to Hajdukovic, gravity in the quantum vacuum arises from the gravitational repulsion between the positive gravitational charge of matter and the (hypothetical) negative gravitational charge of antimatter. While matter and antimatter are gravitationally self-attractive, they are mutually repulsive. (This part is similar to Massimo Villata’s theory from part 1, in which negatively charged antimatter exists in voids rather than in the quantum vacuum.) Although the quantum vacuum does not contain real matter and antimatter, short-lived virtual particles and virtual antiparticles could momentarily appear and form pairs, becoming gravitational dipoles. “If particles and antiparticles have gravitational charges of the opposite sign, a sufficiently strong gravitational field can convert a virtual pair into a real one,” Hajdukovic explained. “It is not a new hypothesis but a consequence of the Schwinger mechanism, well known in quantum field theories.”In the new paper, Hajdukovic calculates that the energy density of the gravitational dipoles in the quantum vacuum is the correct order of magnitude to act as the cosmological constant, or the force causing the Universe’s accelerating expansion. While this agreement may not seem that remarkable at first, it becomes impressive in the context of the much less agreeable predictions of quantum field theory, which predicts the energy density of the quantum vacuum to be at least 30 – and up to 120 – orders of magnitude larger than the observed dark energy density. Hajdukovic’s calculations also estimate that the Universe’s expansion began accelerating when the Universe was about half of its present size, which is only slightly earlier than the prediction of standard cosmology.

Voicestress software is put to the test

first_img Explore further ( — Computer scientists working in a range of departments, from pervasive computing to mobile computing to sensors, will converge in Pittsburgh for the 14th International Conference on Ubiquitous Computing (Ubicomp 2012) on September 5 through 8. They will learn more there about a team’s software that can recognize stress from vocal patterns. The researchers wanted to see if they could successfully train a system to pick up stress through a person’s voice.

Citation: Voice-stress software is put to the test (2012, August 22) retrieved 18 August 2019 from “We propose StressSense for unobtrusively recognizing stress from human voice using smartphones,” say the authors, and they believe they can demonstrate that their StressSense classifier “can robustly identify stress across multiple individuals in diverse acoustic environments.”Their system is trained first to recognize someone’s unstressed voice. StressSense compares this recording to its preprogrammed knowledge of stress-caused physiological changes, such as faster speech and clipped frequency spectrum. The study authors, including Hong Lu of Intel in Santa Clara, California, found the prototype’s stress-recognition accuracy to be 81 per cent indoors and 76 per cent outdoors.Baseline voice rates for a group of people were gathered. According to their system, the person is told first to relax and read a three-minute passage from a book into the phone. Participants were subsequently placed in stressful job interviews to test the system. The study group totaled 14. Thirteen participants were undergraduate students in fields such as geology, psychology, biology, and law. One participant was a PhD student. Audio data was collected using Nexus One phones at 8kHz 16 bit PCM using a custom Android program that runs in the background, according to the paper.The researchers next plan to design, deploy, and evaluate a StressSense Android app. The inevitable question is what good will it do to be told by one’s own smartphone to chill out. The team is confident that the app carries real and practical benefits. Lu said the software has the potential to raise user awareness of stressful events and to help cope. The interest in voice analysis to recognize stress is not new. The study authors point to pioneering work in 1968 when amplitude, fundamental frequency, and spectrograms were analyzed for speech under task-induced stress . They also noted a body of research on stress detection from speech centered around the Speech Under Simulated and Actual Stress (SUSAS) dataset.“Evidence from experiments with SUSAS suggests that pitch plays a prominent role in stress. Other important features are those using energy, spectral characteristics of the glottal pulse, and phonetic variations (speaking rate) and spectral slope.”As for their own study findings, the team pointed out four contributions of their paper. They experimentally show that 1) stress from human voice can be detected using smartphones in indoor and outdoor conversational data; that 2) a universal stress model can be adapted to specific individual users; 3) a stress model can be adapted to unseen environments, lowering the cost of training stress models for different scenarios; and 4) the proposed stress classification pipeline can run in real-time on off-the-shelf Android smartphones.

First instance of ball lightning captured on video and spectrographs

first_imgSome scientific groups, including the Max Planck Institute, have reportedly produced a ball lightning-type effect by discharging a high-voltage capacitor in a tank of water.

The BL is generated by a cloud-to-ground lightning strike. It moves horizontally during the luminous duration. The evolution of size, color and light intensity is reported in detail. The spectral analysis indicates that the radiation from soil elements is present for the entire lifetime of the BL. ( —Researchers in China have captured, for the first time, an instance of ball lightning, on digital video along with spectrographs. The accidental capture, detailed by the team in a paper they’ve had published in Physical Review Letters, offers proof that ball lightning does exist and because it was captured via spectrographs also, offers clues as to how it came to exist.

But until now, because of their rarity no one has ever managed to capture one on tape—that the researchers also captured data on spectrographs only adds to the specialness of the event.The researchers report that they were not out to capture video of ball lightning, instead, they were video-taping lightning strikes as part of a genera research effort. As they were recording, a ball lightning event occurred right in front of their camera. They report that it came into being just off the ground, travelled for about five meters before rising slightly higher and traveling for another fifteen meters before disappearing. The entire event last just over a second and a half.More importantly, the researchers were also recording with spectrographic equipment which allowed them to discern the main elements that made up the ball. They found them to be iron, silicon and calcium, the very same main ingredients in soil.Back in 2000 James Dinniss and John Abrahamson suggested in a paper that ball lightning was likely a result of normal lightning striking the ground. The immense heat, they suggested would be enough to cause silicon oxide in the soil to vaporize—the shockwave from the bolt would then push the gas up into the air where it would begin to glow as it was oxidized in the atmosphere. Six years later Vladimir Dikhtyar and Eli Jerby created what appeared to be ball lightning in a lab by following up on the ideas expressed by Dinniss and Abrahamson. The information from the spectrographs captured by the Chinese team appears to back up the theory as well.The researchers that caught the ball lightning on video also reported that there was a slight anomaly—an intensity fluctuation at about 100 Hz, which they suggested may have been due to the influence of nearby power lines.last_img read more

Physicists design zerofriction quantum engine

first_img Journal information: Scientific Reports ( —In real physical processes, some energy is always lost any time work is produced. The lost energy almost always occurs due to friction, especially in processes that involve mechanical motion. But in a new study, physicists have designed an engine that operates with zero friction while still generating power by taking advantage of some quantum shortcuts. Quantum engines must break down Explore further Scientists have devised a way to run a quantum cycle based on the use of quantum shortcuts to adiabaticity, where friction-like effects are quenched. Shown are the four steps of a quantum Otto cycle, where heat enters (exits) the working medium and those where work is performed by (done onto).

But for quantum technologies on the micro- and nano-scale, quantum fluctuations that are insignificant on large scales start to become prominent. As previous research as shown, the large quantum effects call for a complete reformulation of the thermodynamics laws.What a quantum version of thermodynamics might look like is not yet known, and neither are the limitations or possible advantages of the quantum devices that would be described by such laws. However, one intriguing question is whether it may be possible to build a reversible quantum engine—one in which the engine’s operation can be reversed without energy dissipation (an “adiabatic” process).In the new paper, the physicists have shown one example of a quantum engine that is “super-adiabatic.” That is, the engine uses quantum shortcuts to achieve a state that is usually achieved only by slow adiabatic processes. This engine can achieve a state that is fully frictionless; in other words, the engine reaches its maximum efficiency, while still generating some power.”Shortcuts allow us to ‘mimic’ what would be achieved by running a cycle quasi-statically, i.e., very slowly, while performing transformations at finite time,” coauthor Mauro Paternostro at Queen’s University in Belfast, UK, told “Now, consider for instance a compression or expansion stage of a cycle run using a piston. When doing it at finite time, i.e., non-zero velocity, friction might affect the performance of the transformation. Yet, by using a shortcut to adiabaticity, friction-like effects would get quenched, the cycle performance being the same as that of a quasistatic motor.”The work marks a step toward the key engineering goal in this context, which is to find the maximum efficiency allowed at the maximum possible power. As the scientists note, this pursuit is complicated by the existence of a trade-off between the running time of the super-adiabatic process and the corresponding amount of work dissipated.”This work is one of the first steps into the merging of quantum control and thermodynamics,” Paternostro said. “We have shown that it is possible to use techniques that, to date, have only been used for other goals (population transfer, for instance) for thermodynamic tasks and the engineering of efficient cycles.”Overall, the results suggest the possibility of a frictionless quantum engine operating at maximum efficiency, which has implications in designing micro- and nano-scale motors operating at the verge of the quantum scale. In the meantime, there are still several hurdles to overcome.”I think that the real challenge is the use of such techniques in interacting quantum many body systems, whose inherent complexity and rich phenomenology could be ‘tamed’ by the use of this sort of quantum control,” Paternostro said. “At the end of the day, thermodynamics is a theory of many particles, and its quantum formulation should be able to cope with many-body effects, whose control could hugely benefit from the implementation of schemes similar to the one proposed in our paper. We have new and exciting results, in this context, that will come up soon and that will hopefully have an impact in the community interested in many-body physics and quantum thermodynamics.” Citation: Physicists design zero-friction quantum engine (2014, September 16) retrieved 18 August 2019 from More information: A. del Campo, et al. “More bang for your buck: Super-adiabatic quantum engines.” Scientific Reports.

Archeologists unearth 3300 year old complex in Israel

The content is provided for information purposes only. Initial examination of the ruins suggests the site was an ancient cult complex—a rather large one at that with side walls measuring up to 52×52 feet. Thus far archeologists have uncovered mask fragments (parts that covered the nose), connected cups (their purpose has yet to be discovered), scarabs (stone representations of the beetle typically used as an amulet) and very large vessels known as pithoi.The relics suggest the site was use as a cult complex, likely dedicated to the worship of a god, though the researchers can’t say with any certainty which one that might have been. The most likely candidate, they told the press recently, is the storm god Baal, who was worshiped by many Middle Eastern peoples during the time that the complex was active. Like many others, he was believed to be a fertility deity, one of the most important or popular of the time. Other gods have not been ruled out, including the war goddess Anat. Other evidence of worship was burnt animal bones, suggesting sacrificial rituals.The connected cups are particularly intriguing as examples of them have been seen before—the ones found at the new dig site are believed to have come from Syria, due to their design. Though there is scant evidence of their use or purpose, archeologists generally believe, the researchers report, that they were likely cultic objects. Because of the newness of the site, the artifacts have not yet been tested for residue analysis—the researchers are eager to find out what was held in the large pithoi, some of which were nearly as large as a full grown person—some at the site were sunken and some held smaller vessels inside of them.The site has not been fully excavated yet and leaders of the excavation team noted that unlike most other excavation efforts, digging at Tel Burna, including the newly found complex, can be conducted by amateurs if they are so inclined to help out. Archeologists unearth King David era temple near Jerusalem A team of archeologists working in Israel’s Tel Burna dig site have unearthed the remains of a large stone complex dating back approximately 3,300 years. Information about the finding was presented at the recent European Association of Archaeologists’ meeting held in Istanbul.

Debraj claimed that three students, including the assistant general secretary of the Arts Faculty Students’Union (AFSU) Ushashi, had to be hospitalised today but their condition was now stable. The AFSU said four students, including AFSU chairperson Somashree, had to be admitted to hospital. Around 20 members of the AFSU started a hunger strike on July 6, two days after the university announced that it would admit undergraduate students in English, comparative literature, Bengali, history, political science and philosophy on the basis of board marks, reversing its earlier decision to hold entrance tests The All Bengal University Teachers’ Association, JU chapter, in a letter urged the VC to end the impasse by taking the opinion of all the stakeholders and called for upholding the functional atutonomy of the institution. The governor, in a letter to the university, had also said that while the EC usually takes decisions on different issues faced by the university, the VC was empowered to take certain decision on his own, in case of exigencies. Jadavpur University has been embroiled in controversies since July 4, when the executive council announced its decision to scrap entrance tests for the six subjects. An hour after the announcement, the students had gheraoed the VC and other members of the executive council to protest the move. The gherao, which lasted for 30 hours, was followed by JUTA ceasework, class boycott and indefinite fast by AFSU members.last_img read more
