Photo: UNBAnother US-Bangla plane crash victim died at Dhaka Medical College Hospital (DMCH) on Monday afternoon, taking the death toll from the accident to 50.Shahin Bepari, who was undergoing treatment at the Intensive Care Unit (ICU) of DMCH burn and plastic surgery unit with 32 per cent burn injuries, breathed his last around 4:45pm, said the unit’s coordinator Samanta Lal Sen, reports UNB.On 18 March, Shahin Bepari was brought back to Bangladesh from Nepal by a flight of Biman Bangladesh Airlines and admitted to the DMCH.Earlier, at least 49 people, including 26 Bangladeshis, were killed as an aircraft of US-Bangla Airlines from Dhaka to Kathmandu crashed at Tribhuvan International Airport in the capital of Himalayan country Nepal on 12 March.With the death of Shahin, the number of Bangladeshi nationals killed in the accident rose to 27.Meanwhile, five more Bangladeshi survivors-Mehedi Hasan, Saiyada Kamrunnahar Shwarna, Almun Nahar Annie, Sheikh Rashed Rubayet and Shahreen Ahmed-are now undergoing treatment at the DMCH.last_img read more

Pakistan detains militant suspects after Kashmir attack

Photo: AFPPakistan has detained dozens of alleged militants after a suicide attack in Indian-held Kashmir last month which sent tensions between the nuclear-armed foes soaring, its interior minister said Tuesday.Among those detained in Islamabad’s latest crackdown on banned groups was Abdul Rauf — who a security source told AFP is a younger brother of Masood Azhar — the leader of Pakistan-based militant group Jaish-e-Mohammad (JeM) that claimed responsibility for the February 14 attack.Rauf had been named in a dossier of evidence in that attack given to Pakistan by India, the interior ministry said.”We have launched a crackdown against proscribed organisations and have taken 44 individuals into custody, including Mufti Abdul Rauf and Hammad Azhar,” state minister for the interior Shehryar Afridi told reporters in Islamabad.He did not give any further names, clarify what groups those detained allegedly belonged to, or say if they would face charges.The 14 February attack killed 40 Indian paramilitaries and spurred tit-for-tat air raids between India and Pakistan across the highly militarised Line of Control, the de facto border in the disputed Himalayan region of Kashmir.Both sides claimed they had shot each other’s warplanes down, igniting fears of an all-out conflict as world powers pleaded for restraint.Pakistan captured one Indian pilot, releasing him on Friday in a bid to pull both countries back from the brink, though tensions remain high.Rauf is a little-known younger brother of Masood Azhar, the security source said. He added that “Hammad Azhar” was an alias, but did not say who for.Indian officials were sceptical of the detentions Tuesday. “We have seen Pakistan make arrests before, and then the people are released,” an Indian government source told AFP.India, along with the US, has pressured Pakistan to take action against militancy.”If they still do not mend their ways, We have told them what will happen,” Prime Minister Narendra Modi told an election rally in central India Tuesday.Afridi said Pakistan was “not taking this action under pressure from anyone”. Islamabad has vehemently denied involvement in militant attacks, and said there are no safe havens left for terror groups on its territory.JeM leader Masood Azhar remains in Pakistan, foreign minister Shah Mehmood Qureshi told CNN last week, adding that he was “very unwell” and could not leave his house.last_img read more

Maxwells demons may drive some biological systems

first_imgConventionally, the switching mechanism was thought to operate in equilibrium, where the switch changes between clockwise and counterclockwise motor rotations in a balanced way. An earlier experiment showed that the time interval a flagllear motor spends in a given state (either clockwise or counterclockwise) follows a peaked distribution. Based on Tu’s work, this peaked interval time distribution indicates that the switch operates out of equilibrium. In order to achieve this fast and accurate switching, the switch must be extremely sensitive to the CheY-P concentration. In the non-equilibrium model, Tu shows that this high sensitivity can be explained by the presence of two Maxwell’s demons, which act as the switch’s sensors for the CheY-P. “The easiest way to explain the work of these two Maxwell’s demons is that they are two coincidence counters,” he said. “Each switch can have up to 34 CheY-P regulators bind to it. One of the demons will count the number of bound CheY-P, and if the number is greater than some threshold, say 22, it will switch the motor from CCW to CW; another demon works the opposite way with a low threshold, say 12. If the number of CheY-P bound is less than 12, this demon will switch the motor from CW to CCW.”These “demons” consume energy to do their work, in accordance with the second law of thermodynamics. The more energy the demons use, the more sensitive the switch is. Tu determined the exact amount of energy used per switch cycle, and discovered that it is roughly equal to the work done by one or two protons moving through the membrane near the flagellar motor. Based on this finding, he predicts that the switch may be powered by protons passing through the membrane. This possibility would agree with earlier observations that the average switching frequency depends on the proton flux.As Tu explains, viewing the flagellar motor switch in the framework of a non-equilibrium model could help scientists understand the switching mechanism as an integrated part of the motor system. In biology, many systems operate out of equilibrium, and Tu’s model could help scientists detect interesting non-equilibrium effects. Besides the flagellar motor, he predicts that a similar non-equilibrium mechanism, driven by Maxwell’s demons, could be responsible for a variety of other cellular processes.More information: Tu, Yuhai. “The nonequilibrium mechanism for ultrasensitivity in a biological switch: Sensing by Maxwell’s demons.” PNAS, August 19, 2008, vol. 105, no. 33, 11737-11741.Copyright 2008 PhysOrg.com.

(PhysOrg.com) — According to the second law of thermodynamics, entropy always increases. For example, two bodies of different temperatures, when brought into contact, will eventually mix together to result in a uniform temperature. 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. But, as the physicist James Clerk Maxwell famously suggested in 1871, what would happen if a theoretical demon could stand at a doorway between the two bodies, and only allow high-temperature particles to pass through one way, and only low-temperature particles to pass through the other? The tiny doorman would prevent the two temperatures from mixing, and theoretically prevent entropy. Of course, the demon would use energy to do this job, thus creating entropy itself, and so the second law would not be violated.While Maxwell’s demon was originally considered a thought experiment, similar mechanisms have been discovered for various applications. One example is a Ranque-Hilsch vortex tube, which is a pneumatic device that separates hot and cold air by spinning hot and cold molecules in different directions.Now, a recent study shows that a similar mechanism may drive a motor switch in the bacteria Escherichia coli, and may be responsible for many other signaling systems in biology. Researcher Yuhai Tu at IBM’s T.J. Watson Research Center in Yorktown Heights, New York, explains how E. coli’s Maxwell’s demons work in a recent issue of the Proceedings of the National Academy of Sciences.“There are two related contributions made in this paper,” Tu told PhysOrg.com. “First, a general non-equilibrium mechanism for making a highly sensitive switch (i.e., how Maxwell’s demons can be used to increase sensitivity). Second, a general result on dwell-time statistics (how long a system should stay in a given state before it switches to other states). This result can be used as a diagnostic tool to detect the existence of these demons (or non-equilibrium effects) in an unknown system.”The bacterium contains flagellar motors that drive its motion. A flagellar motor has a switch (a shift gear) whose job is to sense the concentration of a regulator called CheY-P, and then control the rotational direction of the motor to be either clockwise (CW) or counterclockwise (CCW), accordingly. “The purpose of the CW and CCW switch is to control the motion of the cell,” Tu said. “The CheY-P level is the signal (red/yellow/green light) which affects the switch (stop/slow/move). In a very loose sense, CCW results in movement and CW results in switching direction. The bacterium cell needs to control these two types of motions to navigate towards (away from) favorable (toxic) environments.” Video games are a ‘great equalizer’ for people with disabilities Citation: Maxwell’s demons may drive some biological systems (2008, September 10) retrieved 18 August 2019 from https://phys.org/news/2008-09-maxwell-demons-biological.html Explore furtherlast_img read more
