I2T: Image Parsing to Text Description, Proceedings of IEEE [pdf]. (PhysOrg.com) — Scientists at the University of California in Los Angeles (UCLA) have developed a prototype surveillance camera and computer system to analyze the camera images and deliver a text feed describing what the camera is seeing. The new system aims to make searching vast amounts of video much more efficient. © 2010 PhysOrg.com Explore further The system also uses algorithms describing the movement of objects from one frame to another and can generate text describing motions, such as “boat 3 approaches maritime marker at 40:01.” It can also sometimes match objects that have left and then re-entered a scene, and can describe events such as a car running a stop sign.Professor Zhu said at the moment almost all searches for images within video is done using surrounding text, but the new system directly generates text from the images. He also added that the existence of YouTube and other video collections, and the expanding use of surveillance cameras everywhere show that being unable to efficiently search video is a major problem. The I2T system is not yet advanced enough to recognize a large number of images instantly and is not ready yet for commercialization, but the researchers say it is close and needs only “minor tweaks.” The scientists also say they may be able to feed the text into a vocal synthesizer to increase its usefulness.You can now listen to all PhysOrg.com podcasts at www.physorg.com/podcasts-news/ Citation: New surveillance camera system provides text feed (2010, June 3) retrieved 18 August 2019 from https://phys.org/news/2010-06-surveillance-camera-text.html Diagram of the I2T framework. Image credit: Benjamin Yao. The system was developed by Professor Song-Chun Zhu and colleagues Haifeng Gong and Benjamin Yao, in collaboration with the company ObjectVideo, of Reston Virginia in the US. Dubbed I2T for Image to Text, the system runs video frames through a series of vision algorithms to produce a textual summary of the contents of the frames. The text can then be indexed and stored in a database that can be searched using a simple text search. The system has been successfully demonstrated on surveillance footage.The I2T system draws on a database of over two million images containing identified objects in over 500 classifications. The database was collected by Zhu starting in 2005 in Ezhou, China, with support from the Chinese government, but is still not large enough to allow the system to assess a dynamic situation correctly.The first process in I2T is an image parser that analyzes an image and removes the background and identifies the shapes in the picture. The second part of the process determines the meanings of the shapes by referring to the image database. Zhu said that once the image is parsed transcribing the results into natural language “is not too hard.” This document is subject to copyright.

In their paper published in the Proceedings of the National Academy of Sciences, the researchers describe how blind mole rats living nearly side-by-side in the Upper Galilee Mountains, have been found to possess a difference in their mitochondrial DNA, of up to 40 percent.

More information: Possible incipient sympatric ecological speciation in blind mole rats (Spalax), PNAS, Published online before print January 28, 2013, doi: 10.1073/pnas.1222588110AbstractSympatric speciation has been controversial since it was first proposed as a mode of speciation. Subterranean blind mole rats (Spalacidae) are considered to speciate allopatrically or peripatrically. Here, we report a possible incipient sympatric adaptive ecological speciation in Spalax galili (2n = 52). The study microsite (0.04 km2) is sharply subdivided geologically, edaphically, and ecologically into abutting barrier-free ecologies divergent in rock, soil, and vegetation types. The Pleistocene Alma basalt abuts the Cretaceous Senonian Kerem Ben Zimra chalk. Only 28% of 112 plant species were shared between the soils. We examined mitochondrial DNA in the control region and ATP6 in 28 mole rats from basalt and in 14 from chalk habitats. We also sequenced the complete mtDNA (16,423 bp) of four animals, two from each soil type. Remarkably, the frequency of all major haplotype clusters (HC) was highly soil-biased. HCI and HCII are chalk biased. HC-III was abundant in basalt (36%) but absent in chalk; HC-IV was prevalent in basalt (46.5%) but was low (20%) in chalk. Up to 40% of the mtDNA diversity was edaphically dependent, suggesting constrained gene flow. We identified a homologous recombinant mtDNA in the basalt/chalk studied area. Phenotypically significant divergences differentiate the two populations, inhabiting different soils, in adaptive oxygen consumption and in the amount of outside-nest activity. This identification of a possible incipient sympatric adaptive ecological speciation caused by natural selection indirectly refutes the allopatric alternative. Sympatric ecological speciation may be more prevalent in nature because of abundant and sharply abutting divergent ecologies.center_img © 2013 Phys.org Sympatric speciation contributes to island biodiversity Explore further Evolutionary science suggests that new species develop when a natural barrier arises between groups of the same species – water levels rising, for example, causing islands to develop and subsequent divergence of the animal populations. This is known as allopatric speciation. But there’s another way for a new species to develop, some scientists claim, and it has nothing to do with a natural barrier. They suggest that some species diverge even when there is no natural barrier between them. This is known as sympatric speciation, and the researchers in Israel believe they have found an example of it.One part of the Upper Galilee Mountains has a very unique structure – igneous basalt rock has been pushed, via natural forces, up against chalk bedrock. The result is a very clear geographical dividing line with different kinds of plants growing in different soil types on either side of the line where the two meet. The researchers have found two groups of blind mole rats – one group lives on and above the basalt, while the other the chalk, that don’t appear to comingle. Despite being the same species, the two groups appear to have stopped mating with one another at some point in the past, leading to differences in their DNA. And this, the team suggests, might be an example of the birth of a new species.There are some obvious holes in the theory, of course. The team isn’t able to prove that the moles weren’t separated physically somehow in the past, nor can they say for sure that over time, the moles on either side of the line will eventually be unable to mate and reproduce with each other – a necessity for describing them as being of two different species. Still, the research has sparked renewed interest in the idea of sympatric speciation, and that will likely lead to more research being conducted in areas with similar geographic dividing lines.last_img read more

Science journal issues expression of concern over chemistry paper

first_imgThis is a computer graphic of an RNA molecule. Credit: Richard Feldmann/Wikipedia Research integrity—what it means, why it is important and how we might protect it The paper outlined a way to use RNA to grow crystals of palladium metal, which opened the door to the idea that RNA might be involved in processes in nature that resulted in the production of inorganic materials. After it was published in Science, Franzen alerted the university to discrepancies in the work, possibly due to intentional misconduct. After several months, the university conducted an investigation into the allegations made by Feldheim and eventually found that the researchers had failed to properly index their electron microscopy data, contradicting statements in their paper—more negligence than misconduct. Apparently not satisfied with that result, Feldheim contacted officers at the University of Colorado, after Eaton and Felhdeim moved there—the university’s research-integrity official looked into the matter and concluded that the issue was more one of a disagreement between colleagues than an example of misconduct.Several years later, after the paper had been cited over 135 times, the National Science Foundation got involved—the work by the team was looked at in more detail and the result was a report that suggested the trio had overstated their findings and omitted details. A recommendation of misconduct was made. The agency did not make such a judgment but did produce a letter reprimanding the researchers and banned them from receiving research funds from the NSF until they take “specific actions to correct publications containing the misleading results,” to remedy the errors.The expression of concern by McNutt is meant to alert other researchers to the possibility of errors in the paper, warning them that it might not be a good idea to use or cite the paper in their own research efforts, and to notify readers that the journal is working with the authors to gain a better understanding of what occurred. Once that happens, the journal intends to either print a retraction or a correction. Journal information: Science (Phys.org)—The journal Science has published an “editorial expression of concern” by its editor-in-chief, Marcia McNutt, regarding a research paper the journal published back in 2004. The paper titled “RNA-Mediated Metal-Metal Bond Formation in the Synthesis of Hexagonal Palladium Nanoparticles” by Bruce Eaton and Daniel Feldheim, chemists at North Carolina State University and grad student Lina Gugliotti was partially discredited after a colleague at the same university, Stefan Franzen, filed a complaint with the school challenging the work done by the research trio.

The cold hard facts Scientists redefine the chemical history of interstellar water

first_img Explore further REMPI spectra of photodesorbed H2O after 157 nm photoirradiation of water ice at 10 K. (A) Vapor-deposited H2O ice. (B) H2O ice produced in situ by means of hydrogenation of O2. (C and D) Simulated spectra with Trot = 200 K and (C) Tspin = 200 K and (D) Tspin = 10 K. Indications (JKa,Kc) are rotational assignments, where “o” and “p” denote ortho and para, respectively. Trot and Tspin represents rotational and spin temperatures, respectively. Credit: Prof. Tetsuya Hama, Hokkaido University. Dr. Tetsuya Hama and Phys.org discussed the paper he and his colleagues published in Science, starting with the challenges of showing that water desorbed from ice at 10 kelvin shows a statistical high-temperature ortho-to-para ratio (OPR) of 3 even when the ice is produced in situ by hydrogenation of O2, a known formation process of interstellar water. “Detecting ortho-H2O and para-H2O separately is the main difficulty in studying the H2O ortho-to-para ratio,” Hama tells Phys.org. “Ordinary analytic techniques, such as electron or single-photon ionization, cannot distinguish them. We also need high sensitivity for detecting ortho- and para-H2O, since only a small amount of H2O is desorbed from ice following photoirradiation or thermal heating.” In addition, Hama adds, it’s necessary to produce a sufficient amount (10-20 monolayers) of water ice in situ on a substrate at 10 K. In their experimental setup, the researchers produce water ice by O2 hydrogenation (a chemical reaction between molecular hydrogen and another compound or element) at 10 K – but it requires seven hours. “These technical problems – that is, ortho- or para-state selective detection and in situ ice preparation – are the main reasons that studying the OPR of H2O desorbed from ice is challenging, and thus, the conventional proposal that the OPR is related to the condensation or formation temperature of ice has not been tested experimentally.”An interesting aspect of the study was the goal of clarifying the origin of the anomalous OPRs observed for interstellar H2O due to the role of gas-phase processes being poorly understood. “Our results suggest that the OPR of H2O desorbed from ice is the statistical value of 3 regardless of the formation process of the ice, so the anomalously low OPR of interstellar H2O may be an indicator of the gas-phase processes that the H2O experienced after desorption,” Hama explains. “However, ortho-para conversion would not occur in the gas phase by radiation or nonreactive collisions, because they are spin-forbidden.” Hama therefore believes that the gas phase ortho-para conversion of H2O may occur by chemical (proton-exchange) reactions, likely candidates of which are proton-exchange reactions with ions such as H+ [ortho-H2O + H+ → para-H2O + H+] or H3O+ [ortho-H2O + H3O+ → H3O+ +para-H2O]. These two reactions are almost thermo-neutral, Hama points out, but the reverse processes can be slightly endothermic and thus very slow – especially at low temperature – because of the energy difference of ortho and para H2O in the gas phase [∆E = 23.8 cm−1 (34.2 K)]. Thus, these reactions might lead to para-enrichment of H2O in cold (< 30 K) molecular clouds. OPR of H2O as function of temperature. Curve A is calculated from Eq. 1 with the gas-phase constants. Approximated curves B to E are calculated from Eq. 9 with DE values of (B) 23.8 cm−1 (gas-phase), (C) 20 cm−1 (H2O in Ar matrix), (D) 10 cm−1, and (E) 1.0 cm−1. Approximated curves B to E tend toward 9, not the statistical OPR value of 3, because only the lowest ortho- and para-rotational states are considered in Eq. 9, and thus the contribution of the rotational degeneracy is not cancelled as in curve A from Eq. 1. Details of Eqs. 1 and 9 in paper. Credit: Prof. Tetsuya Hama, Hokkaido University. Since ordinary analytic techniques cannot distinguish ortho and para H2O, the scientists addressed these challenges by employing the Resonance Enhanced Multi-Photon Ionization (REMPI) technique. Originally developed for spectroscopic investigations in the field of physical chemistry, REMPI allows ortho-para state selective detection of H2O by tuning the photoionization laser wavelength – and it has very high sensitivity. The researchers think that REMPI perfectly suits the study the OPR of H2O desorbed from ice, and have designed and built a novel experimental apparatus that enables both in situ ice production and REMPI detection of ortho- and para-H2O desorbed from ice at 10 K. "Scientifically," Hama points out, "we suggest that the ortho-para nuclear spin physics of H2O in ice is totally different from that in the gas phase. The conventional proposal that the OPR is related to the ice formation temperature implicitly assumes that para-H2O is more stable than ortho-H2O in ice, as it is in the gas phase." However, Hama notes that the thermodynamic stability of para-H2O in the gas phase stems from the rotational energy difference between para- and ortho-H2O [(JKa,Kc=000 and JKa,Kc=101, respectively). In ice, both ortho- and para-H2O do not rotate by hydrogen bonds - meaning that unlike the gas-phase, the thermodynamic stability of ortho- and para-H2O should be comparable in ice at 10 K. Moreover, he adds, fast continuous ortho–para interconversion would occur in ice owing to intermolecular proton-magnetic interaction, which does not occur in the gas phase."I therefore think that the conventional proposal should reconsider these differences in ortho-para nuclear spin physics of H2O between the gas and ice phases. Our findings can also apply to other hydrogen-bonding systems such as NH3 in ice, so we can predict that the OPR of NH3 desorbed from ice would also be statistical, and cannot be used to deduce the surface temperature of interstellar dust."One of the finding's key results was invalidating the assumed relation between OPR and temperature, thereby elucidating the chemical history of interstellar water from molecular clouds and processes in the early solar system, including comet formation. Moreover, regarding the OPR of H2O in a comet, the study explained why nearly all of the observed OPRs lie within 1 or 2 of the statistical value. "For the OPRs of H2O in cometary comae, the story is hopefully somewhat simpler." (A coma is the nebulous envelope around a comets' nucleus.) "The OPR of H2O should be statistical (=3) at desorption from the comet nucleus, not indicating the past formation temperature of the ice nucleus. In comae, the collision rate and the total number of collisions of H2O with other H2O molecules, ions, electrons, and dust grains are predicted to be too small to induce efficient conversion." Therefore, the observed OPRs of H2O in cometary comae would not greatly change from the statistical value of 3 at desorption from the nucleus, which explains why OPR values of H2O in cometary comae lie within 1 or 2 of the statistical value.The paper also challenged approaches that assume that the OPR of water desorbed from ice is related to the ice formation temperature on the dust, and provided a reinterpretation of OPR's importance as a physicochemical tracer by considering gas-phase processes may clarify new or missed roles of interstellar H2O in star and planet formation. "The OPR has been a key observable in astronomy and planetary science," Hama tells Phys.org. "For example, the OPR of H2O in a comet has been considered a cosmogonic indicator" – that is, a finding based on the astrophysical study of the origin and evolution of the universe – "that gives the past formation temperature (30 K) of the ice nucleus in the solar nebula some 4.6 billion years ago. However, we experimentally disproved the conventional assumption of OPR's relation to temperature, such that it cannot be used to deduce the surface temperature of interstellar dust at H2O formation or condensation." In short, the researchers have made it necessary to develop a new interpretation of the anomalously low OPR of H2O."The origin of the anomalous OPRs is still an open question for now, but we can find a new direction in which the gas-phase processes may be important," Hama continues. "The OPR may be an indicator of the gas-phase nuclear-spin conversion processes that the H2O experienced, such as reactions with H+ and H3O+." This, in turn, may yield detailed information about the physical and chemical conditions – including temperature, the types of ions, and their abundances – of local environments where the gas-phase nuclear-spin conversion of H2O occurs. "Our finding is the first step towards understanding the significance of the OPR of interstellar H2O, which has been unknown for almost 30 years since its first observation. Approaches from quantum physics and chemistry as well as astronomy and planetary science are certainly needed for future studies, which is truly an interdisciplinary science."Regarding next steps, Hama tells Phys.org that while in the present study, the researchers measured the OPR of gaseous H2O desorbed from ice by photoirradiation and heating, they could not measure the OPR of nascent H2O formed on ice, the nuclear spin conversion time of H2O on ice, and the nuclear spin state of H2O in ice. "These are still unsolved, challenging problems, but the nuclear spin conversion time could be measured with ortho- or para-H2O separation techniques." In addition, he continues, recent progress in observational studies in astronomy and planetary science has succeeded in providing detailed physical and chemical information – species, abundance and its spatial distribution, energy state (electronic, vibrational, rotational, nuclear-spin), isotope fractionations, and other metrics – about interstellar molecules."These can help us to understand the evolution of stars and planetary systems," he says. "However, to obtain a proper meaning from observations, we must understand the physics and chemistry of molecules in extraterrestrial conditions well. These are often extreme environments, such as very low temperature (10 K), and there are still many unknowns and unexpected phenomena. We would like to tackle the physics and chemistry in these extreme environments."As esoteric as the team's research may appear, their findings are relevant to a host of other research disciplines. "Our results advance fundamental understanding of nuclear-spin conversion and the separation of nuclear spin isomers of molecules, both of which are important challenges in physics and chemistry. For example," he illustrates, "para enrichment of H2O has been studied for its application to highly-sensitive nuclear magnetic resonance (NMR) spectroscopy. However, our results imply that if H2O could be enriched in ortho or para states, it would become a statistical mixture (OPR=3) once it is incorporated into ice. This means that the isolation of ortho- or para-water in ice and its application to NMR study is quite difficult."

To study these gas-phase reactions, we have to treat ortho and para H2O separately (nuclear spin-state–dependent), but it is a challenge both theoretically and experimentally in current physics and chemistry." More information: T. Hama et al, Statistical ortho-to-para ratio of water desorbed from ice at 10 kelvin, Science (2015). DOI: 10.1126/science.aad4026 For the past 30 years, the significance of the anomalously low ortho-to-para ratios (OPRs) of gaseous water (H2O) in interstellar space has remained unknown. (In ortho hydrogen molecules, both nuclei spin in the same direction, while in para hydrogen the nuclei spin opposite directions.) Recently, however, scientists at Hokkaido University, Sapporo, Japan found that water desorbed (that is, released from or through a surface) from ice at 10 kelvin shows a statistical high temperature OPR of 3 rather than the lower values typically found, even when the ice is produced in situ by a known formation process of interstellar water known as O2 hydrogenation. This invalidates the assumed relation between OPR and temperature and requires a reinterpretation of the low OPRs will help elucidate the chemical history of interstellar water from molecular clouds and processes in the early solar system, including comet formation.

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. Climate scientists have been debating among themselves what will happen as the planet warms. In addition to changes in temperature, there are likely to be changes in weather patterns and precipitation. One thing they have not been able to agree on is whether the planet will experience more or less precipitation. In this new effort, the researchers suggest that an equation widely used to help predict changes in weather patterns and precipitation levels is flawed because researchers have failed to properly use one of its parameters.Scheff explains that the equation, the Penman-Monteith equation, uses temperature, surface radiation, wind speed and humidity as inputs. As one factor changes, such as temperature, changes can be seen in the others. But, he notes, many who use the equation have failed to take into account the closure of leaf stomata in plants that occurs when carbon dioxide levels increase, resulting in less evaporative loss. The equation allows for this with a parameter that permits inputting surface resistance to evaporation in non-arid locations. Many have simply been setting it to zero. The researchers argue that doing so has caused erroneous results that suggest an increasingly drier planet. They found that allowing this parameter to depend on carbon dioxide changes allowed accounting for leaf stoma closure. They report that using the equation in such a way showed that the planet is likely to experience more precipitation in some areas, less in others and that some areas may remain unchanged—a finding that would appear not only more logical but in line with several other theoretical models.

Hermit crabs found to use vibration to ward off wouldbe shell evictors

first_imgA pair of researchers with Dartmouth College has found that Pacific hermit crabs use vibration to ward off other crabs trying to steal their shells. In their paper published in the journal Biology Letters, Louise Roberts and Mark Laidre describe their study of hermit crabs attempting to protect their shells and what they found. Journal information: Biology Letters Explore further Hermit crabs are unique among crustaceans—they have soft abdomens that are not protected by a naturally grown shell. To protect themselves, hermit crabs have to take possession of the shell made by another mollusk. From there on, they carry the shell around and hide from predators inside of it. But because they do not grow the shell themselves, hermit crabs must obtain new shells periodically as they outgrow the ones they have. The process by which they obtain a new shell generally involves either finding one that is uninhabited or taking one away from another hermit crab. In places where empty shells are scarce, competition for shells can become intense. In this new effort, the researchers have found one of the ways hermit crabs ward off the advances of would-be shell thieves—by using vibration.Noting that hermit crabs sometimes vibrate their shells, the researchers designed experiments to find out why. They consisted of grabbing one of the empty shells off the beach and affixing a device inside of it that made the shell vibrate. They then placed the shell on a beach where hermit crabs resided and waited for a hermit crab to wander by to check it out. The vibration device was connected to a wire that ran along the beach for several yards to where the researchers were waiting hidden behind an umbrella. When a crab approached the shell, they had the option of doing nothing, applying gentle vibration or applying strong vibration.The researchers report that when the shell vibrated very strongly, a shell-seeking crab would immediately climb down and run away. When feeling just a small vibration, however, the crab tried to turn the shell over, the first move when attempting to evict a current tenant. The crabs did the same thing when encountering no vibration. The researchers claim these findings suggest hermit crabs have learned to vibrate as a means of warding off interlopers. ‘Junk’ science?

The last of Pankhawallas

first_img“I owe my life to the lord. If he’s asked me to serve people, I’d do it for the rest of my life,” says Nizam, a young man probably in his 30’s roaming in the ‘Hazrat Nizammudin Auliya Dargah’ with his gigantic fan precariously held by a bamboo. His statement and his actions prove sheer contradiction to us being incensed to think of summer with a whole lot of fuss.Nizam is accustomed to pick up random people and fan the heat away from them on a daily basis. Albeit he never asks for tips. He has been doing this for the last twenty years. “Das baras ke the jab yaha aae Ajmer se ab malik ka hi khate hain toh unhi ke yahan seva karenge na,” he says. (I was ten when I came here from Ajmer, I live on what the Lord has given so I have to serve where he is).

The ‘Pankhawallas’ were professionals who were paid according to their enthusiasm and a good session at the Lord’s house.Nizam and Habibullah are like the last prolific rays of the sun, who keep this profession alive. They make up for great optics when they roam in the shrine with their elephantine fans and pristine smiles. “koi bura nahi hai” (nobody’s bad) is what Nizam had to say when asked which shrine was his favourite. They were four earlier, two left and found other ways for a living due to low earning. Nizam and his partner earned the greatest on Thursdays. “Bade aur meherbaan aadmi log jumerat ko aate hai” (big and kind men come on Thursdays) they said.

I like to be here, as long as the rule of the lord triumphs, I am here only) says Habibullah when asked why he didn’t continue with his business.But stories like that of Nizam and Habibullah bring joyous salvation in two ways, one for reviving and respecting the dying profession.
