Scientists discover new water waves

first_img In their study, which is published in a recent issue of Physical Review Letters, the scientists explain how they discovered the new waves. They confined water inside a Hele-Shaw cell, which is a container made of two parallel glass plates separated by a small gap. In this case, the plates were positioned vertically, like the two sides of an ant farm. The plates were 30 cm wide, and the gap between them was just 1.5 mm. The water inside was about 5 cm deep.The researchers mounted the Hele-Shaw cell on a shaker, which vertically vibrated the cell and the water inside. While carefully controlling the vibration frequency and amplitude, they recorded the water surface deformation with a high-speed camera.When the researchers slowly increased the oscillation amplitude, two-dimensional standing waves with large amplitudes began to form on the water’s surface. As the researchers explained, these waves are called Faraday waves, which form on the surface of a vibrating fluid when the vibration frequency exceeds a certain value, and the surface becomes unstable.The researchers observed two different shapes of Faraday waves, one having even symmetry and the other having odd symmetry. The even symmetry can be seen as a vertical “mirror” symmetry between the wave’s left and right sides. The odd symmetry of the second wave is only approximate, since the wave’s lower half is not exactly the same shape as the upper half. Because the researchers used an external probe to briefly perturb the surface, they think that the different wave patterns are likely attributed to the probe motion.

The observed waves belong to a different category of solitary waves.”When trying to understand how surface instabilities could have caused these waves to form, the researchers encountered some problems due to the waves’ large amplitudes, since general amplitude equations describe waves with significantly smaller amplitudes. But in general, the researchers think that the novel wave patterns likely arise from the overlap of flat and wavy regions, both of which result from shaking-induced instabilities. The instabilities may involve mechanisms that also play a role in other fields, such as nonlinear optics, chemistry, and biology, as well as in sea waves.“The main interest of our work obviously applies to sea nonlinear waves, and strengthens our knowledge concerning the formation of ocean waves of large amplitudes (giant ‘rogue’ waves or ‘tsunamis’),” Rajchenbach said.

In a new study, Jean Rajchenbach, Alphonse Leroux, and Didier Clamond of the University of Nice-Sophia Antipolis in Nice, France, have reported the observation of two new types of standing waves in water, one of which has never been observed before in any media. When analyzing the standing waves, the researchers found that the two-dimensional even wave resembles the profile of a three-dimensional “axisymmetric oscillon,” a type of wave that has previously been observed at the surface of a layer of vibrating bronze beads. To the researchers’ knowledge, the odd standing wave has never been observed in any fluid media. The odd standing solitary wave.

New calculations suggest Jupiters core may be liquefying

first_imgJupiter. Photo courtesy of NASA (PhysOrg.com) — Jupiter, the largest planet in our solar system, may be causing its own core to liquefy, at least according to Hugh Wilson and colleague Burkhard Militzer of UC, Berkeley. They’ve come to this conclusion after making quantum mechanical calculations on the conditions that exist within the big planet. In a paper published on the preprint server arXiv, and submitted to Physical Review Letters, the two explain that because the gas giant has a relatively small core made of mostly iron, rock (partly magnesium oxide) and ice, and sits embedded in fluid hydrogen and helium all under great pressure from the planet’s gravity (which has created very high temperatures (16,000 K)), there is a likelihood that the core is liquefying due to the heat and pressure exerted on the magnesium oxide. Researchers moving closer to a soluble solution to Haber-Bocsh process Citation: New calculations suggest Jupiter’s core may be liquefying (2011, December 21) retrieved 18 August 2019 from https://phys.org/news/2011-12-jupiter-core-liquefying.html © 2011 PhysOrg.com This document is subject to copyright.

The content is provided for information purposes only.center_img Journal information: Physical Review Letters Calculating the possibility of the magnesium oxide liquefying had to be done to predict the outcome because recreating the environment that exists inside of Jupiter for experimentation purposes isn’t feasible. They have in essence shown that magnesium oxide, when exposed to such high temperatures and pressure, has high solubility, which of course means a high probability of dissolving into a liquid. In a previous study, the team also made calculations showing that the core ice would likely be dissolving as well.The findings suggest that Jupiter’s core might not be as big as it once was, though it currently weights about as much as ten Earth’s (the whole planet weighs as much as 318 Earth’s). This implies that the core could eventually be reduced down to nothing at all. And if that’s the case, than those who study exoplanets, particularly the giant gas variety, will have to do some rethinking, because those others might not have a core at all, contrary to conventional wisdom.Unfortunately, the calculations the two performed can’t give a rate of erosion, thus a timeline for how long it’s taken for the core to come to its current size can’t be made, nor can predictions be made on how long it might take for the core to disappear altogether; both of which would be useful in helping to predict the ages of other gas giants out beyond our solar system. Luckily, NASA has a space probe on the way to measure Jupiter’s gravitational field more accurately, though it won’t get there till 2016; that should give scientists plenty of time to consider the impact these new findings might have on their current models regarding giant gas planets. More information: Rocky core solubility in Jupiter and giant exoplanets, arXiv:1111.6309v1 [astro-ph.EP] arxiv.org/abs/1111.6309AbstractGas giants are believed to form by the accretion of hydrogen-helium gas around an initial protocore of rock and ice. The question of whether the rocky parts of the core dissolve into the fluid H-He layers following formation has significant implications for planetary structure and evolution. Here we use ab initio calculations to study rock solubility in fluid hydrogen, choosing MgO as a representative example of planetary rocky materials, and find MgO to be highly soluble in H for temperatures in excess of approximately 10000 K, implying significant redistribution of rocky core material in Jupiter and larger exoplanets.via Wired Explore furtherlast_img read more

Study finds mimicry increased in scarlet kingsnake snake after disappearance of coral

first_imgAdult Scarlet King Snake, Florida Locale. Credit: G-Bartolotti/ Wikipedia SKCC BY-SA 3.0 Coral snakes are venomous, as most people are aware. They’re also one of the more identifiable of the venomous snakes due to their unique black, yellow and red bands along the length of their body. Scarlet kingsnakes on the other hand, are not venomous. Instead they are Batesian mimics, a term used to describe harmless creatures that mimic the appearance of those that are dangerous in the hopes that they will be mistaken for them by predators and be left alone. Both types of snakes once lived in the North Carolina Sandhills area, which allowed the scarlet kingsnake to become a mimic of the coral snake. But, something unexpected happened around 1960 that caused the coral snakes to disappear from the area—no one knows why, but it left the kingsnakes without a model to copy.With no examples to emulate, Akcali and David Pfennig figured that kingsnakes would likely have lost some of their mimicry over the past half century. To find out if they were right, the obtained samples of coral snakes captured before they disappeared and compared them with samples of kingsnakes captured at various times since then. To their surprise, they found that the sudden disappearance of the coral snake had caused the kingsnakes to look even more like them, not less.In hindsight, the research duo suggest that had they given the situation more thought, they might have predicted what they found. They note that as the numbers of coral snakes started to decline, those kingsnakes that looked less like coral snakes likely suddenly became targets of predators, while those that looked more like the venomous snakes survived, leading to a quick evolutionary change. They suggest that the trend will not continue long, however, as time passes and predators either forget what coral snakes looked like or become bolder during lean times and overcome their fear of them.

More information: Rapid evolution of mimicry following local model extinction, Biology Letters, Published 11 June 2014 DOI: 10.1098/rsbl.2014.0304AbstractBatesian mimicry evolves when individuals of a palatable species gain the selective advantage of reduced predation because they resemble a toxic species that predators avoid. Here, we evaluated whether—and in which direction—Batesian mimicry has evolved in a natural population of mimics following extirpation of their model. We specifically asked whether the precision of coral snake mimicry has evolved among kingsnakes from a region where coral snakes recently (1960) went locally extinct. We found that these kingsnakes have evolved more precise mimicry; by contrast, no such change occurred in a sympatric non-mimetic species or in conspecifics from a region where coral snakes remain abundant. Presumably, more precise mimicry has continued to evolve after model extirpation, because relatively few predator generations have passed, and the fitness costs incurred by predators that mistook a deadly coral snake for a kingsnake were historically much greater than those incurred by predators that mistook a kingsnake for a coral snake. Indeed, these results are consistent with prior theoretical and empirical studies, which revealed that only the most precise mimics are favoured as their model becomes increasingly rare. Thus, highly noxious models can generate an ‘evolutionary momentum’ that drives the further evolution of more precise mimicry—even after models go extinct.last_img read more

Physicists demonstrate new way to violate local causality

first_img The physicists, Gonzalo Carvacho et al., from institutions in Italy, Brazil, and Germany, have published a paper on the demonstration of the violation of bilocal causality in a recent issue of Nature Communications.In general, the idea of local causality is usually taken for granted: objects can influence other objects only when they are physically close together, and any correlations between distant objects must have originated in the past when they were closer together. But in the quantum world, distant particles can be correlated in ways that are impossible for classical objects, unless these distant particles can somehow influence each other.To determine whether local causality has been violated, physicists perform Bell tests, which attempt to violate Bell inequalities. If a Bell inequality is violated, then either locality or realism (or simply “local realism”) has also been violated.There are dozens of different versions of Bell inequalities, but currently they all make the same assumption: that the correlations between particles all originate from a single common source. In real experiments, however, particles and their correlations can come from many different sources.To address this issue, the new paper considers a new type of Bell inequality that accounts for the fact that the two sources of states used in the experiment are independent, the so-called bilocality assumption. By violating this new type of Bell inequality, the researchers have for the first time violated bilocal causality, indicating the presence of non-bilocal correlations that are completely different than other types of quantum correlations.The researchers also showed that, in certain situations, it’s possible to violate bilocal causality but not any other type of local causality. This finding further suggests that this type of violation is truly different than any standard local causality violation.”Our work is an experimental proof-of-principle for network generalizations of Bell’s theorem,” coauthor Fabio Sciarrino at the Sapienza University of Rome told Phys.org. “We experimentally demonstrated how bilocality can be considered a powerful resource enlarging our current capabilities to process information in a non-classical way.”Overall, the results contribute to the perspective that the standard Bell inequalities are just one particular type of more general phenomena. Further exploring this idea could guide the design of future experiments that may reveal greater insight into the violations of local causality and how they might be used in applications. The new non-bilocal correlations, for instance, could be used as a resource for establishing highly secure quantum communication channels in complex quantum networks.In the future, the researchers plan to extend the experimental demonstration to larger quantum networks. They also noted that the current experiment is subject to loopholes, just like any other Bell test, other than the recent loophole-free Bell tests. The physicists hope that one day a loophole-free test may also be developed for bilocal causality violation.”A natural next step is to experimentally realize larger quantum networks by adding more nodes and more entangled sources,” Sciarrino said. “Our current research plans address the study of the bilocality in quantum networks under strict conditions of reference frames between the different parties in order to highlight another characteristic of this new resource.” Citation: Physicists demonstrate new way to violate local causality (2017, April 21) retrieved 18 August 2019 from https://phys.org/news/2017-04-physicists-violate-local-causality.html This document is subject to copyright.

In Vermont A Case of One Man Whose Gun Was Se

first_img by NPR News Melissa Block 8.22.19 5:00am This summer’s mass shootings in El Paso, Texas, and Dayton, Ohio, accelerated calls for more red flag or extreme risk laws in the states as well as helped jumpstart bills in Congress. The laws allow courts to order the seizure of firearms from those believed to pose an imminent danger to themselves or others. Seventeen states and the District of Columbia have passed them.But, while the political focus may be on mass shootings, states are using the laws far more often to prevent cases of individual gun violence, including suicide.In gun-friendly Vermont, Republican Gov. Phil Scott signed a package of gun control legislation into law in April 2018, including an extreme risk law. He said he had been “jolted” into action by what he called a “near miss”: an alleged plan by an 18-year-old to carry out a mass shooting at a high school in Fair Haven, Vt.In the 16 months since the law has been in effect, Vermont, with a population of about 627,000, has issued some 30 extreme risk protection orders, or ERPOs.One of them was served on 28-year-old Sean Laskevich, of Springfield, Vt. Appearing recently in Windsor County Superior Court, Laskevich chose not to contest the ERPO filed against him, so that he wouldn’t complicate the criminal case he’s also facing. Under the terms of the ERPO, Laskevich is prohibited from purchasing, possessing, or receiving a firearm for six months – or longer, if the order is renewed. The incident that led to his legal trouble started just before 10 p.m. on July 26, when the Springfield Police Department started getting a flood of 911 calls:”There’s a guy screaming and hollering.””He’s just screaming at the top of his lungs.””I’m pretty sure I just heard a gunshot.””I just heard him let off like 10 rounds.””Oh! Oh! I just heard another shot!”It all went down in the woods behind the house that Laskevich shares with his girlfriend, Amanda Barbour, and her children.”Sean had a legitimate breakdown, to say the least,” Barbour says. “He just in one night couldn’t take it anymore. And he felt that maybe everybody and everything was better off without him.”That night, Laskevich headed down a steep slope, across a stream, and up the opposite bank, armed with his .45 caliber Glock pistol, and started firing off shots. More than a dozen officers responded to the scene: among them, Springfield Police Chief Mark Fountain, who was roused out of bed. “I grabbed my AR-15. I had my AR-15 ready to go,” he says. “As quickly as I arrived I was told by one of the officers that a number of times [Laskevich] had discharged his firearm. I believe one of the bullets had ricocheted and they heard it whizzing over their head.”According to a police affidavit, Laskevich was shouting that he was distraught over his recent DUI arrest after he crashed his truck, as well as relationship trouble with Amanda. He repeatedly raised his pistol to his head, yelling “I am done.” “This is how I’m going out.”Amanda Barbour heard that, too, as well as another threat: “He wanted to be taken out,” she says. “He announced to the officers, ‘I want you to take me out.'”In other words, suicide by cop.At one point, Barbour says, they all heard a single shot from far back in the woods. Then: silence. “Oh, did I scream for a minute,” she says. “That made our hearts stop.”It was a relief, she says, when Sean started yelling again.The standoff and negotiation went on for nearly two hours. In the end, Laskevich gave himself up, was disarmed, and taken to the hospital for mental health screening. He faces misdemeanor criminal charges, as well as the ERPO, which falls under civil law. Laskevich declined to speak with NPR, on the advice of his criminal defense lawyer.Despite all that happened that night, Amanda Barbour says she’s confident that Laskevich poses absolutely no threat. Taking his gun away, she says, is not right.”Obviously what Sean did was not OK in any way, and he has answered to the consequences,” she says. “I do not feel that man should have to relinquish his Second Amendment for a minute because of this. I don’t feel there’s any danger whatsoever in [my] or my children’s safety when it comes to that man having a firearm. As a matter of fact, it’s a little unnerving not having one.”Talk to prosecutors and law enforcement officers in Vermont and they’ll tell you that the state’s red flag law has proved most useful in cases like this one, where someone poses a risk of suicide. Vermont has a higher rate of suicide, and suicide by gun, than national rates. In cases like these, red flag laws offer an important tool to protect public safety, says police chief Fountain. “It doesn’t always have to involve a person committing a crime,” he says. “It can just simply be a person, let’s say, who is experiencing a mental health crisis involving a weapon, where they are just threatening harm to themselves.”While it’s mass shootings that have become the catalyst for enacting red flag laws, Vermont prosecutors are dubious that that’s their best use.”Has it prevented a mass shooting thus far?” asks Erica Marthage, state’s attorney for Bennington County. “Who knows? Who can tell? In my view, clearly the overwhelming [use] is for domestic-related fatalities and suicide. It’s another safeguard.”David Cahill, the state’s attorney for Windsor County, is similarly skeptical.”I don’t for a minute believe that red flag laws will in any meaningful way interrupt the epidemic of mass shootings in this country,” he says. “I hate to say this,” he continues, “but I believe the mention of red flag laws in response to what happened in El Paso and in Dayton is a bit disingenuous. It’s intended to be a distraction…. To say that red flag laws would solve the problem of mass shootings would be to suggest that all you need to do surgery is a scalpel.”To really solve the problem, Cahill says, would require a different, much harder conversation.”The tough part is that I can’t think of a way to solve this problem without amending the Constitution,” he says. “I’m not suggesting that I have language to rewrite the Second Amendment, because I don’t. But it’s worth having the conversation about our modern weapons, this 18th century document, and what we can do to honor our history but also preserve life for ourselves and future generations.” Cahill, himself a gun owner, adds, “We’re not having that discussion. But we should.”Copyright 2019 NPR. To see more, visit NPR. In Vermont, A Case of One Man Whose Gun Was Seized Under… last_img read more

China comes calling

Tourism in China has greatly expanded in the last few decades since the beginning of reforms. It has a large number of wonderful tourist destinations.With all this in mind, the China Happy and Healthy Tour was kicked off, serving as a platform for other countries to get an insight into China. The event, hosted by China National Tourism Administration and Chinese Embassy at the DLF Promenade on 22 September, showcased the colourful culture and rich tourism resources in different parts of China.The convention also served as a golden opportunity for tourism communities of two countries — ­India and China — to interact with each other and explore the respective tourism markets in order to expand and enhance business.‘China and India, as two close neighbours, enjoy long- standing good relationship in the history characterised by friendly exchanges.  China owes its Buddhism culture to India and India draws inspirations from Chinese products like tea, porcelain and silk. The exchanges have deeply enriched our respective cultures and become an unfailing driving force for evolution of two great civilisations,’ said HE Zhang Yan, Chinese Ambassador to India.In recent years, in the domain of tourism, bilateral co-operation between the two countries has been expanding rapidly. ‘Today over 40 flights shuttle between China and India every week. The Chinese first stop visits to India has reached 1.3 lakh, increasing by more than 20 per cent over 2010,’ he added. read more

The policies of state and loss of soul

first_imgSunday evening saw Shashi Tharoor all charged up, despite suffering from a little cold, to interact with an auditorium filled with people about his latest book Pax Indica, a seminal work on India’s foreign policy. The evening hosted the fourth edition of Books & Authors, where Tharoor was featured to educate the audience and discuss with them the intricacies described in his manuscript.The well known author, veteran UN official and diplomat, and currently the Union Minister of state for HRD, Tharoor, graced his presence at CSOI Complex where the book was introduced by Ujjwal Singh Bhatia, who was till recently India’s ambassador to the WTO at Geneva. The evening of interactive session was moderated by Sanjeev Chopra, the current Joint Secretary in the Ministry of Agriculture. Also Read – ‘Playing Jojo was emotionally exhausting’Pax Indica, or the Indian peace, is the thirteenth feather in the cap of the author-diplomat turned politician Tharoor. The author’s basic hypothesis is that India can use a combination of her size, trade prowess, soft power and growing influence in the world to ensure an age of domestic transformation. As far as Tharoor is concerned, Pax Indica is a foreign policy that allows India to play a role in developing a contemporary ‘peace system’ that will help ‘promote and maintain a period or co-operative co-existence’. Also Read – Leslie doing new comedy special with NetflixPax Indica has been written with precision, clarity and an idea to introduce the concept of India’s Foreign Policy.Tharoor who emphasises upon India’s need to ‘cultivate good relations with countries that can assist’ us in his manuscript and thus in the process become ‘partners in our fundamental objective of keeping our people safe, secure and free’ goes some distance in explaining the seeming contradictions in India’s foreign policy.It is commendable, Tharoor said, ‘The book ensures to draw the attention of readers to the neglected Indian Foreign Service and weaves the past problems encountered by various Ministers and the laxity on the part of successive governments although he himself is a part of the system.’ He added that the book is about India and India’s position in the world. The last few chapters discuss on forward looking will the initial chapters talk about the present situation.During the interaction, Tharoor also cited few of the instances about the present political system and said that politicians by and large tend not to think beyond the next election. He even said, ‘We made our new policy with our head and not our heart and in the process we have lost our soul.’last_img read more

Govt hikes limit of eway bill for intrastate movement to Rs 1

first_imgKolkata: State Finance and Industry minister Amit Mitra said on Thursday that the state government has increased the threshold limit to Rs 1 lakh for the electronic-way or e-way bill in case of movement of goods within the state, from the existing limit of up to Rs 50,000.He further announced that the generation of such bill for an intra-state movement of goods is being exempted, where goods are being sent to job workers.”The e-way bill with regard to movement of goods within the state originating and terminating within Bengal (intra-state movement but without passing through any other state), would be required where the consignment value exceeds Rs 1 lakh. Such limit is up to Rs 50,000 in other states. We have raised the limit keeping in mind the interest of our small traders,” Mitra said at the Kolkata Garment Expo 2018, organised by Bengal Readymade Garments Manufacturers and Traders Welfare Association. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedQuoting the notification that was issued by the Commissioner of State Tax, Bengal on Thursday, Mitra added: “Generation of e-way bill for an intra-state movement of goods is exempted where such goods are being sent to a job worker for job work, being sent from one job worker to another, or are being returned to the principal after such job work and where such transportation is not for final delivery of the finished goods.”It may be mentioned that the Central government had launched the e-way bill system from April 1, for moving goods worth over Rs 50,000 from one state to another and the same for intra or within the state movement was rolled out from April 15 in a phased manner. Such a bill is required when the value of taxable consignment, along with the tax value, is more than Rs 50,000.
