The Road n´ Air craft is called Transition. It is a light sport aircraft that will take to the skies and then return to airport, fold up its wings and drive home. Terrafugia, Inc located in Woburn, Massachusetts is the brain child of MIT graduates of the school of Aeronautic and Astronautics. Terrafugia translated from Latin means “escape from land.” The official specification provided by Terrafugia of the craft are as follows. It is a two seat, side- by -side light sports aircraft. It has a G-Tow of 1320 pounds with a useful load capacity of 550 pounds. It has a 20 gallon fuel capacity and a 100 hp Rotax 912 S (four stroke) engine. It has a wingspan of 27.5 feet, length of 18.75 feet and height of 6.75 feet. The on the road width is 6.5 feet. The Transition is designed for short hops with a range of 460 miles or less. It utilizes Super-unleaded gasoline as a source of fuel. It has a take off distance over 50 foot obstacles of 1700 feet. The craft Vs is 51 mph and Vr is 80mph. The Transition and its team of designers, mechanics and owners made a special appearance in July, 2007 at the prestigious AirVenture Show in Oshkosh, Wisconsin. During the exhibit, Transition wing was cycled through a complete fold and extend process over 500 times without a hitch. The demonstration is equivalent to almost five years of usage. The designers have left nothing overlooked in the design for strength and endurance. The wings have two blue bumper strips near the tip of the wings to prevent door dings when Transition is in its road mode. There are dual electromagnetic locks that when engaged for the road mode, provide a tight hold on the wing close to the fuselage. The Terrafugia team is leaving no detail unnoticed. The prototype is currently a work in progress, with an anticipated completion date of late 2008. Terrafugia, Inc plans to make its first delivery of the Transcend in 2009. The anticipated selling price of Transcend is $148,000. Currently, the company is taking pre-release orders requiring a five per cent deposit that will be held in trust and fully reimbursable until a purchase agreement is executed.

Photo by Saurabh Palan Unimpressed by 4-D developments they had seen at haptics conferences and theme parks, the team of students – Saurabh Palan, Ruoyao Wang, Nathaniel Naukam, Edward Li, and Katherine J. Kuchenbecker – set out to make gunshots, knife slashings, and the feeling of blood dripping from the wounds more realistic than the other gadgets they had experienced provided.Using a first person shoot game (FPS Game: HALF LIFE 2 – Gun Shot Moment), the team set up their own game mode source code with a Source Engine wiki, complied it, and ran it through a Valve Steam platform. Then they designed their own map and game level and created their own 3-D first person shooter game.The TGVs are stuffed with solenoid actuators in the chest and on the front and back of the shoulders, and they are timed to go off when your character gets shot. They even get you where your character gets shot. Getting stabbed is no sweat either. The vibrating motors embedded around the vest simulate that experience. Oooh. Aaah. Why the vest can even simulate blood flowing from a wound. Ugh. Immersive Game System Allows Physical Interaction Between Players Half-Life 2 scene via sharkyextreme.com Tactile Gaming Vest.

Engineers investigate why the cochlea is coiled

The content is provided for information purposes only. Simulated beam patterns of straight and spiral cochleas: While the straight cochlea generates beam patterns without any vertical variation, the spiral cochlea generates beam patterns that vertically localize the sound source. Image credit: Xun Huang, et al. ©2012 EPLA Citation: Engineers investigate why the cochlea is coiled (2012, June 14) retrieved 18 August 2019 from https://phys.org/news/2012-06-cochlea.html Copyright 2012 Phys.org All rights reserved. This material may not be published, broadcast, rewritten or redistributed in whole or part without the express written permission of PhysOrg.com. The researchers, Xun Huang, Chi Xu, and Long Bai, at Peking University in Beijing, China, have published their study on the coiled cochlea’s ability to provide vertical sound localization in a recent issue of EPL.The idea that the cochlea’s spiral shape has perceptual benefits is somewhat surprising, since currently most cochlear models used in research simplify the cochlea as a straight system. This simplification seems justified because numerical simulations have shown that a straight cochlea and coiled cochlea have a similar mechanical oscillation amplitude, which describe the vibrations that get sent to the brain. However, recent research has suggested that there may be significant differences in the way that straight and coiled cochlea respond to sound.“One previous paper stated that the spiral’s graded curvature enhances the cochlea’s mechanical response to low frequencies,” Huang told Phys.org. “Our work is the first one in sound localization. Basically, most previous works focus on ‘low level’ functions, such as mechanical response. We show that sound localization may be one of the potential functions of the cochlea’s coiled geometry, which was assumed solely developed for saving space.”As all individuals with good hearing can attest, the ears can detect the source of a sound in both the horizontal and vertical planes. Horizontally, a sound source produces a time and volume difference between the left and right ears because the ears have different horizontal positions. But since the left and right ears are positioned at the same height on the head, a sound source in the sagittal plane (the vertical plane that divides the body into left and right halves) produces no difference between the two ears based on the source’s vertical position. Instead, two parts of the ear called the pinna and tragus help mammals achieve vertical sound localization.However, recent experiments with the brown bat (Eptesicus fuscus) have suggested the existence of an alternative mechanism for vertical sound localization. After researchers disabled the function of the bat’s tragus, its vertical sound localization capability was weakened, but only temporarily. After a period of adaptation, the capability was partially restored due to an alternative mechanism. It’s not over when it’s over: Storing sounds in the inner earcenter_img More information: Xun Huang, et al. “Is the cochlea coiled to provide sound localization?” EPL, 98 (2012) 58002. DOI: 10.1209/0295-5075/98/58002 (Phys.org) — The word “cochlea” comes from the Latin for “snail shell.” While this inner ear component has a clear spiral shape, it’s currently unclear why that is. In the 1980s, scientists supposed that the shape evolved solely for space conservation, but in the past few years researchers have questioned this view and proposed that the spiral curvature could have perceptual benefits as well. In a recent study, a team of engineers has added evidence to this view by performing simulations showing that a coiled cochlea can detect the source of a sound in the vertical direction significantly better than a straight cochlea. As the researchers show here, one potential alternative way of achieving vertical sound localization could be the coiled shape of the cochlea. To begin, they proposed that the human hearing system might adopt a method similar to adaptive beamforming, a technique used for directional signal processing, to process sound signals for the brain. In their simulations, the researchers modeled the thousands of hair cells in the 3.5-cm-long cochlea as a sensor array in the context of beamforming. Then they compared how this sensor array perceived sound pressure when arranged in a straight vs. spiral geometry. Their results revealed that straight and spiral cochleas generate different beam patterns, i.e., acoustic images of the sound sources. For all sound sources, the straight cochlea generates a beam pattern that spans the entire vertical range, providing no vertical sound localization. In contrast, the coiled cochlea generates different and much narrower beam patterns for different sound sources, providing significantly improved vertical sound localization. For horizontal sound localization, the straight and coiled cochleas show comparable performance.The finding that vertical sound localization can be improved purely by geometric changes supports the argument that the cochlea’s coiled shape is useful not just for conserving space. The results could be helpful for designing cochlear implants and echolocation systems, in which sound waves are used to detect objects.“From the very beginning, we were actually studying bat flight control based on sound echolocation,” Huang said. “As you can see, vertical sound localization is very important for bat flight. However, the biological information of a bat’s cochlea is not so accessible. Hence, we used the human cochlea as a test case.”Huang added that they are currently designing experiments in an anechoic chamber to test the results of these simulations.

Researchers devise a means to control chemical reactions in individual atoms

first_img Journal information: Nature Physics Citation: Researchers devise a means to control chemical reactions in individual atoms (2012, July 25) retrieved 18 August 2019 from https://phys.org/news/2012-07-chemical-reactions-individual-atoms.html © 2012 Phys.org Explore further More information: Controlling chemical reactions of a single particle, Nature Physics (2012) doi:10.1038/nphys2373AbstractTraditionally, chemical reactions have been investigated by tuning thermodynamic parameters, such as temperature or pressure. More recently, laser or magnetic field control methods have emerged to provide new experimental possibilities, in particular in the realm of cold collisions. The control of reaction pathways is also a critical component to implement molecular quantum information processing. For these studies, single particles provide a clean and well-controlled experimental system. Here, we report on the experimental tuning of the exchange reaction rates of a single trapped ion with ultracold neutral atoms by exerting control over both their quantum states. We observe the influence of the hyperfine interaction on chemical reaction rates and branching ratios, and monitor the kinematics of the reaction products. These investigations advance chemistry with single trapped particles towards achieving quantum-limited control of chemical reactions and indicate limits for buffer-gas cooling of single-ion clocks.via Arstechnica (Phys.org) — In the early days of chemistry, finding out what happened when two or more chemicals were mixed together led to the development of all manner of new materials and to deriving useful events, such as the production of heat or light, or things exploding. As the science progressed however, researchers found they wanted to know more about what really goes on when chemicals react, but were unable to find out due to the massive number of interactions that occur during even the most ordinary chemical reactions. Nowadays, researchers want to delve even deeper, to discover what goes on at the quantum level. To that end, a team working at the Cavendish laboratory in Cambridge, UK has developed a way to monitor and control one of the most basic chemical reactions, the meeting of two dissimilar individual atoms. In their paper published in Nature Physics they describe how they were able to do so by setting up special experiments in a cold environment using a laser. Discovery could pave the way for quantum computing Under normal conditions, when two atoms meet, usually nothing happens. There is no attraction force between the two thus no reason for them to interact. When one or both are ions, things are different of course as the ions have either more or less electrons than stable atoms, causing them to have an electric charge. It was this property that the team used when setting up their experiments, which were meant to serve as an observational study, not to create something new, to see what happens at the quantum level.In their experiments, the team used a magnetic field to isolate two different types of atoms, a ytterbium ion and a neutral rubidium, in a very cold environment to slow things down. But prior to pushing them together with a laser, they first excited the ytterbium ion by shooting it with laser light to inject it, so to speak with kinetic energy. That energy they noted, could result in movement due to heat ejection or in the production of photons.Next, they ran two different types of experiments. In the first, they turned off the lights and watched as the two atoms eventually came near one another, to see if the interaction between the two would result in the release of photons, i.e. light. It did not, instead, it resulted in both atoms moving around in the trap at higher speeds.In the second experiment they used a laser to push the energized ion towards the neutral atom and found that in some, but not all cases, an ion was exchanged, causing the ytterbium atom to become neutral and the rubidium to become ionized; a clear example of a controlled chemical reaction between just two atoms. The researchers noted that the spin state of the atoms made a difference in the outcome of the reaction, meaning that the atomic nucleus of the atom had an impact, which goes counter to conventional thinking.The experiments and results the researchers achieved show that chemical reactions can not only be studied at the quantum level, but controlled as well, a finding that will likely have a major impact on both chemistry and physics research going forward.

Health budget likely to get 6 boost

first_imgAiming to provide affordable health for all, the Modi-led NDA government is set to increase outlays for health ministry in the second budget to be presented by Finance Minister Arun Jaitley on Saturday. According to highly-placed sources, the health sector is set to get about six per cent hike in comparison to the last fiscal’s final budgetary allocation. The increased budgetary allocation would be for diagnosis sector to save people from life threatening diseases such as Tuberculosis, Cancer, Malaria, AIDS, etc, the source further added. If sources are to be believed, the health sector will get above Rs 2,000 crore more in the budget making the final figure of allocation to Rs 35,000 crore for 2015-16. Also Read – Need to understand why law graduate’s natural choice is not legal profession: CJI“The proper diagnosis will help in detection of life threatening diseases at its early stage which would help in saving several precious lives,” the source further added. Nearly 5 lakh people die of cancer every year in the country, while over 10 lakh are newly diagnosed with some form of the disease, while almost 5 lakh people have died of TB.  In case of Malaria, the estimated death figure is of about 1.5 lakh out of over 5 crore cases recorded.It’s worth mentioning that the Finance Minister had earmarked Rs 39,237.82 crore for the sector in his first budget presentation in July last year, but Rs 6,000-crore was slashed from the coffer citing the reason that funds remained unutilised in the ministry’s budget making the final outlay to Rs 33,000 crore only.last_img read more

Internet addiction may weaken your immune system

first_imgSpending too much time online can damage your immune function, warns a new study. People with greater levels of internet addiction problems are 30 per cent more likely to catch colds and flu than those who are less addicted to the internet, the findings showed.“Those who spend a long time on the internet experience reduced immune function as a result of simply not having enough contact with others and their germs,” explained one of the researchers Phil Reed, professor at Swansea University in Wales, Britain. Also Read – ‘Playing Jojo was emotionally exhausting’“We found that the impact of the internet on people’s health was independent of a range of other factors, like depression, sleep deprivation and loneliness, which are associated with high levels of internet use and also with poor health,” Reed noted in a statement released by Swansea University.The study also suggested that those who are addicted to the internet may suffer stress when they are disconnected from the net, and this cycle of stress and relief associated with internet addiction may lead to altered levels of cortisol – a hormone that impacts immune function.  Also Read – Leslie doing new comedy special with NetflixResearchers evaluated 500 people aged  between 18 to 101 years old. Those who reported problems with over-using the internet also reported having more cold and flu symptoms than those people who did not report excessive use of the internet. Previous research has shown that people who spend more time on the internet experience greater sleep deprivation, have worse eating habits and less healthy diets, engage in less exercise, and also tend to smoke and drink alcohol more.  These behaviours too can harm their immune system and increase vulnerability to diseases.last_img read more
