Electric Cars and Hybrids Ready to Go High End

first_img © 2010 PhysOrg.com Finnish firms announce electric car plans Explore further (PhysOrg.com) — Recently, the big news at the 2010 North American International Auto Show was all the electric cars and hybrids. Indeed, hybrid and electric cars are ready to go high end, with a number of companies, from small start-ups to major names, rolling out high performance and luxury cars that use some version of an alternative to gasoline. Electric 65 Coupe. Image source: gizmag.comcenter_img SSI-Racing offers the Electric 65 Coupe, a vehicle that holds three world records for speed. It has high performance, and might even be in the running for the fastest car period — forget about just being the fastest electric car. It has a range in the neighborhood of 300 miles, depending on how you drive it. Which is pretty good for any car’s ability to drive. Of course, this high performance car is a little out of the range of the mass market at around $100,000.Other cars shown off at the Auto Show include the Cadillac XTS Platinum, a plug-in hybrid concept car and the Audi e-tron concept car (complete with four wheel dive). These high end cars are likely to be quite expensive, and out of reach for many of us. (But Cadillac and Audi are out of my reach anyway.) So far, these are mostly concept cars, but the fact that auto makers are presenting them indicates that they are getting ready to see if there would be some interest in this market.If you are a little more interested in something that perhaps costs a little less, other car makers are offering new versions of hybrid and electric cars as well. Hyundai is offering a plug-in concept, and Honda is offering the CR-Z as a sort of updated (and gasoline alternative) CR-X. Of course, once we’re at the point where hybrid and electric are available for the high performance driver, the technology developed should eventually become less expensive, and more widespread, helping more people get access to these types of cars. And, naturally, if you can afford some of the high end vehicles, it appears that you won’t have to wait too much longer to see them in hybrid or electric form. This document is subject to copyright.

Study suggests dinosaurs killed off by more than one asteroid

The content is provided for information purposes only. Image credit: NASA. Professor David Jolley of Aberdeen University in Scotland, and Professor Simon Kelley of the Open University, led a team studying the Boltysh crater, which was discovered in 2002. The Boltysh crater is only 24 kilometers in diameter and therefore much smaller than the Chicxulub at over 180 km across.The team studied fossilized plant pollen and spores found in the mud that filled the Boltysh crater, and found that ferns colonised the area soon after the impact, but there was another colonisation a meter above the first, suggesting a second asteroid impact had occurred elsewhere causing repeat devastation. The researchers attributed this second spike, which occurred two to five thousand years later, to the aftermath of the Chicxulub impact.Ferns are known to colonise devastated areas rapidly after disasters, so layers of fern spores known as “fern spikes” are considered to be good indicators of impact events in the past.The theory that an asteroid impact caused the extinction of the dinosaurs and other species was first put forward in 1980, at which time it created a great deal of controversy until the crater at Chicxulub was discovered and dated to 65 million years ago. Other theories for the mass extinctions include enormous volcanic eruptions of the Deccan Traps in India about the same period that would have spewed toxic gases into the atmosphere. There is also a theory the asteroid impact triggered global earthquakes that in turn caused the Deccan Traps eruptions.Professor Kelley said it is possible evidence will be found in future for more impact events around the same time, suggesting dinosaurs and many other species may have been wiped out due to the effects of an asteroid shower lasting thousands of years. (PhysOrg.com) — Dinosaurs, along with over half of other species, became extinct at the end of the Cretaceous period about 65.5 million years ago, and many scientists believe this was due to a single impact with an asteroid that hit at Chicxulub in the Gulf of Mexico. Now a study published in the Geology journal proposes the impact that produced the Boltysh crater in the Ukraine may also have been involved in the extinctions, and there may have been a shower of asteroids or comets. © 2010 PhysOrg.com New Blow for Dinosaur-Killing Asteroid Theory Citation: Study suggests dinosaurs killed off by more than one asteroid (2010, August 31) retrieved 18 August 2019 from https://phys.org/news/2010-08-dinosaurs-asteroid.html Explore further More information: Two large meteorite impacts at the Cretaceous-Paleogene boundary, David Jolley et al., Geology, v. 38 no. 9 p. 835-838. doi:10.1130/G31034.1last_img read more

Dog park lit by dog poop

first_img Image credit: The Park Spark project Japanese project aims to turn CO2 into natural gas Methane digesters are used in many places around the world for cooking, heating and lighting. They can use almost any organic materials, and large scale digesters often use materials such as cow manure. The results of methane combustion are CO2 and water, and while CO2 is a greenhouse gas, methane is over 20 times more potent. Explore further © 2010 PhysOrg.com Image credit: The Park Spark project (PhysOrg.com) — A methane digester called “Park Spark” has been installed in a dog park in Cambridge, Massachusetts. The device produces methane by bacterial digestion of the dog excrement, and the methane is used to light a gas-burning street lamp. More information: parksparkproject.com/home.html People walking their dogs are encouraged to collect the feces, place them into the supplied biodegradable doggie bags and drop them into the digester feeding tube. They then turn a hand crank to stir the mixture of excrement and anaerobic bacteria in the Spark Park digester and help the methane rise to the top where it is burned constantly in the lamp, like an “eternal flame”.The bacteria are confined to an underground container and the methane is piped underground to the lamp. Methane is the colorless and odorless gas that forms the major component of “natural gas” used for cooking and heating. The idea was the brainchild of Matthew Mazzotta, a conceptual artist, and the project was partly funded by the Council of the Arts at Massachusetts Institute of Technology.The team hopes there will be enough methane generated to power other objects in the park and surrounding community, such as shadow projection boxes, tea carts, or popcorn stands, but the main aim is to demonstrate to the community that waste is a precious resource. “As long as people are walking dogs and throwing away dog poo, a flame can burn,” they say on their website. The eternal flame of the lamp is intended as a reminder of the “redundant and unquestioned” nature of our behavior, and will burn until someone comes up with a better idea for using the energy available.

A toss of the dice reveals the truth

R. Soc. B July 27, 2011. doi: 10.1098/rspb.2011.1228 The research, led by Julia Jones and Freya St John from Bangor University in the United Kingdom is being used in South Africa to question ranchers regarding the killing of protected leopards.Getting people to admit that they have done something illegal is notoriously difficult, but this new method has created a way that seems to make the respondents more comfortable in revealing the truth.When a person is being questioned, they are first given a simple dice. They are told that before answering a question, they must throw the dice and that the researcher would not be able to see what number is rolled. If they throw a number one, they must respond to the question with ‘no.’ If they throw a number six, they must respond with the answer ‘yes.’ All other numbers they are to answer the question with a truthful answer.With this little catch, a respondent’s ‘yes’ answer may not always be ‘yes’ and a ‘no’ may not always be a ‘no.’ Because of this fact, respondents seem to be more willing to give truthful answers when the numbers two through five are rolled.The researchers have also tested this randomized response technique with suspected drug users and compared question results with hair sample drug screening tests and found that they get much more accurate results from the respondents that are administered questions using the dice method.The method is being used in South Africa, not to criminalize ranchers for killing the leopards, but to help target conservation efforts. In areas where ranchers are likely to kill these animals, compensation may be provided to ranchers who have lost livestock due to the predators.last_img read more

NVIDIA takes one step closer to Linux support

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. Sad news: Linux fans, especially gamers, have expressed frustration in not being able to enjoy the most out of mobile computers that carry the Optimus switching technology as a power-saving mechanism.Linux users have had the option of checking out the Bumblebee project, which notes that “Many recent notebooks with a discrete nVidia card in it and an i3/i5/i7 processor use the nVidia Optimus technology to improve battery life. Unfortunately, this software solution is only available in Windows 7 and later.The Bumblebee Project is a set of tools developed by people aiming to provide Optimus support under Linux (legacy nVidia hybrid graphics is supported too) while waiting for kernel and drivers to support these notebooks.”Even Linus Torvalds let loose on his frustration bordering on disgust earlier this year at an entrepreneur session in Finland. He was asked why NVIDIA did not offer support for its GPU under Linux. Torvalds responded that NVIDIA was a thorn and that he thought it very sad that NVIDIA was being difficult about it. But back to some good news. The latest word is that NVIDIA is working to achieve Linux compatibility with its Optimus graphics switching technology. In a recent e-mail sent to a developer listserv, NVIDIA software engineer Aaron Plattner expressed remarks that indicate NVIDIA is working on Linux support. Plattner in the e-mail said that he has created a working proof of concept driver.Reader comments to news sites reporting the NVIDIA engineer’s e-mail have been favorable, in fact happy. Compatibility moves will benefit NVIDIA audiences as well as fans of Linux. Hopes are that the two will work things out. Certainly among the hopefuls are those who use their laptops for gaming and need better battery life. Running Linux on Optimus-equipped laptops, for many, will be ideal. More information: bumblebee-project.org/center_img (Phys.org)—Good news: NVIDIA has a technology called Optimus which since its 2010 launch is regarded as a great extender for notebook, netbook, and ultrabooks. Some NVIDIA fans think favorably of Optimus as “awesome” in the way it can tap into the discrete GPU when needed to conserve power. They like the way battery life is preserved as GPU power is switched off when not needed and switched on when needed again. As the company explains, NVIDIA Optimus technology automatically and instantaneously uses the high performance NVIDIA GPU for GPU-Compute applications, video, and 3-D games; and low power integrated graphics for applications such as web surfing or email. The Optimus approach in “dynamic” switching based on application needs is notable and according to reports a growing number of laptops from the commercial majors are equipped with Optimus.

Unconventional quantum systems may lead to novel optical devices

first_img Journal information: Nature Physics © 2017 Phys.org Blind quantum computing for everyone Citation: Unconventional quantum systems may lead to novel optical devices (2017, August 22) retrieved 18 August 2019 from https://phys.org/news/2017-08-unconventional-quantum-optical-devices.html The physicists, led by Peng Xue at Southeast University in Nanjing, have published a paper on the PT-symmetric quantum walks in a recent issue of Nature Physics.”We present an experimental work tying together three concepts—-non-unitary quantum walks at a single-photon level, PT symmetry, and topological edge states originating from Floquet topological phases,” Xue told Phys.org. “Each of these three concepts has attracted much attention in the past years in the scientific community. The interplay of these elements in our experimental system will no doubt give rise to rich physics.”The new results build on discoveries made over the past 20 years regarding a new class of quantum systems called non-Hermitian Hamiltonians that deviate from conventional quantum systems. In general, the Hamiltonian of a quantum system, which is a measure of its total energy, must have eigenvalues that are real rather than complex numbers, where the eigenvalues are associated with the physical properties of the quantum system. For many decades, it was thought that Hamiltonians must be mathematically described using Hermitian operators, since Hermitians always have real eigenvalues.Although being Hermitian is sufficient for a Hamiltonian to have real eigenvalues, in 1998 physicists discovered that Hamiltonians can be non-Hermitian and still have real eigenvalues, as long as they obey PT symmetry. This discovery opened up a whole new class of quantum systems for physicists to explore. Currently, the study of PT-symmetric non-Hermitian systems is an area of active research that holds promise for a variety of applications, particularly in the field of optics.The new study contributes to this research by demonstrating single-photon PT-symmetric quantum walks. Previously, physicists have theoretically investigated these systems, but the new study marks the first experimental demonstration due to the challenges involved in amplifying single photons. “A PT-symmetric quantum walk is a non-unitary extension of the unitary quantum walk, which is in turn a quantum mechanical version of the classical random walk,” Xue explained. “Just as PT-symmetric non-Hermitian Hamiltonians broaden the horizon of conventional quantum mechanics, a PT-symmetric quantum walk represents a new kind of quantum walk with unique features that are quite different from those of a unitary quantum walk.”This demonstration, in turn, led the researchers to experimentally demonstrate exotic properties called Floquet topological properties in PT-symmetric quantum walks for the first time. The scientists observed that Floquet topological edge states arise between regions with different bulk topological properties, suggesting that these systems contain intriguing quantum phenomena awaiting further exploration. Floquet topological properties are characterized by a pair of topological numbers, and controlling these properties may lead to the development of new quantum optical devices. “I think our work may lead to a new generation of synthetic PT-symmetric systems,” Xue said. “In PT-symmetric classical systems, recent progress may lead to applications in optical switching, modulation, sensors, wireless power transfer, and so on. While our experiment demonstrates Floquet topological states (a special topological matter with time-periodic drives) driven by PT-symmetric quantum dynamics, it provides a new platform where the interplay of PT-symmetric quantum dynamics and topological properties not only offer a quantum mechanical version of PT-symmetric systems, but may also lead to potential applications in quantum information, quantum computation, and quantum sensing.” Explore furthercenter_img (Phys.org)—Physicists have experimentally demonstrated an optical system based on an unconventional class of quantum mechanical systems that could lead to the development of new quantum optical devices. The system is called a “PT-symmetric quantum walk,” since it consists of single photons that occupy a superposition of states, called quantum walks, that obey parity-time (PT) symmetry—the property in which a system’s coordinates in space and time can have their signs reversed without inherently changing the system.

China Arrests Australian Writer On Espionage C

first_imgChina Arrests Australian Writer On Espionage Charges by NPR News Scott Neuman 8.27.19 1:54am A Chinese-born Australian writer detained for months in China has been formally arrested on charges of espionage, officials in Canberra confirmed on Tuesday.Yang Hengjun, a former Chinese diplomat who reportedly became an Australian citizen in 2002 but retains a Chinese passport, has also lived and worked in the United States.He is the author of three spy novels set in China, according to Reuters. In the past, he has written voluminously on his blog about the rule of law, democracy and human rights, according to news.com.au. However, according to Reuters, in recent years, he has stayed away from sensitive topics and concentrated instead on running an import-export business.Yang was first detained seven months ago in China’s southern province of Guangzhou after arriving there from New York en route to Beijing, according to the news agency. Australia’s Foreign Minister Marise Payne says Yang has been held under “harsh conditions” and that Canberra has “serious concerns” for his welfare.”There is no basis for any allegation Dr. Yang was spying for the Australian government,” Payne said of Yang, who has a Ph.D. from the University of Technology in Sydney.She said she was “very concerned and disappointed” and would “advocate strongly” for his release.Rob Stary, an Australia-based attorney for Yang, said the Chinese government has given no details on the charge of espionage.A China-based lawyer for Yang, Shang Baojun, was quoted by The Sydney Morning Herald as saying there would be an investigation for “at least two months” and “if they find him guilty, the case will be handed over to prosecutors.”According to the Herald, those close to Yang believe his academic work and pro-democracy activism may be the reason for his arrest.Yang’s wife, Yian Xiaoling, a Chinese citizen who is also reportedly a permanent resident of Australia, was prevented from leaving China and questioned by Chinese authorities, The Guardian reported. Payne said she had spoken to Chinese officials twice and had written to him on multiple occasions in the past several months.”It is important, and we expect, that basic standards of justice and procedural fairness are met. I respectfully reiterate my previous requests that if Dr. Yang is being held for his political beliefs, he should be released,” she said.Yang faces more than 10 years in prison if found guilty.Copyright 2019 NPR.

His masters words

first_imgAs a tribute to Gurudev Rabindranath Tagore, four prominent choreographers presented some stunning performances based on the translations of some of Tagore’s poems alongside the Bengali originals at India Habitat Centre’s Stein Auditorium. The evening was also a token of love and affection towards Padmashree Utpal Banerjee, who turned 80 on 27 September. So what’s the connection between Utpal Banerjee and Tagore you ask? Here’s the answer – Banerjee has penned 10 books on Tagore’s dance, drama and songs, creating a record by publishing seven of them within a year, which has been recognised in Limca Book of Records. Also Read – ‘Playing Jojo was emotionally exhausting’He has also written a book  Tagore’s Mystique of Dance which is prescribed as text-book for courses on dance in Visva Bharati University, Santiniketan. Banerjee is also a Tagore Research Scholar (under Ministry of Culture) and a translator for National Sahitya Akademi, who has published these volumes. The choreographers – Rama Vaidyanathan with Dakshina Vaidyanathan (Bharatanatyam), Padmashree Shovana Narayan (Kathak), Padma Shri Bharati Shivaji (Mohiniyattam) and Santosh Nair’s Sadhya (Mayurbhanj Chhau and Contemporary) – took on Tagore’s works and presented them in their own signature styles on stage. Also Read – Leslie doing new comedy special with NetflixThe evening also included the launch of Banerjee’s four volumes of English poems which has been translated from Tagore’s satirical and whimsical rhymes. Shovana Narayan, picked one of the ‘nonsensical’ versse from the Khapchhada series of Tagore, choosing the piece on Motilal Nandi, a character that we can all identify with. Very often in our lives, learning of grammar and vocabulary have eluded us and left us frustrated. So was the case with Motilal Nandi. Dakshina Vaidyanathan performed Rabibar which is a child’s innocent complaint about why Sunday takes a long time to come. Rama Vaidyanathan presented Shishu Bholanath which is about a mother reveling in her naughty and vivacious child who goes around destroying everything around him. In her performance she addressed Bholanath – Lord Shiva, the creator and the destroyer. The music was been composed by vocalist Ranita Dey who also sang the poems. Padmashree Bharati Shivaji along with students – Olga, Lakshmi Ramakrishnan and Deepthi Nair presented an extract from Janmakatha where the mother is asked by her child where did she pick him from? Astonished by his queries, she explains how from the very beginning of evolution of the Universe he has been there with her. Santosh Nair’s Sadhya presented a choreographed piece titled Kalpnik which is based on Tagore’s two poems from the fantasy volume namely The Dream (Swapan) and There was a Tiger (Ek Chhilo Bagh). The poem Swapan is about the magic dream of the child to become a cloud and Ek Chhilo Bagh brings forth a tiger who speaks the human language and displays all the human emotions. The choreography revolves around the dream of an individual who falls asleep while reading the fantasy volume and how the readings reflect in her dreams creating a fiction of its own.last_img read more
