first_imgAn aedes mosquito. File PhotoThree more persons have died of dengue and 1,460 others have been infected with the mosquito-borne disease, showing a fall in the number of dengue patients than Friday’s 1,719, reports UNB.The fresh deaths were recorded in Dhaka and Faridpur on Saturday while the new infections in 24 hours till Saturday morning.In Dhaka, a woman lost her battle to dengue while undergoing treatment at Dhaka Medical College Hospital (DMCH) in the morning.The deceased was Monwara Begum, 45, wife of Saiful Islam of Chamakpur village in Mithamain upazila of Kishoreganj district.Saiful said Monwara was admitted to Kishoreganj Sadar Hospital after she was diagnosed with dengue about 10 days back.She was taken to the DMCH on 13 August where she died at the intensive care unit around 10:45am, he said.In Faridpur, two persons, including a college student, died of dengue at Faridpur Medical College Hospital. The deceased were Sumon Bashar Raj, 18, son of Mizanur Rahman of Changpur village in Magura district and a second-year student of a government college in Magura, and Yunus Sheikh, 55, son of Aynal Sheikh of Rajbari.Mostafizur Rahman Bulu, assistant director of the hospital, said Sumon was admitted to the hospital on 12 August and he breathed his last around 10:00am.The victim’s father said Sumon was detected with dengue at Magura Hospital on 8 August and later sent to the medical college hospital.Yunus died of the mosquito-borne disease at the hospital around 7:00pm, said hospital director Kamda Prasad Saha.He was taken to the hospital on 12 August with dengue, he said.Of the new dengue infections, 621 were reported in Dhaka city alone while the rest in other divisions, according to the Health Emergency Operation Centre and Control Room of the Directorate General of Health Services (DGHS).The number of dengue patients was 1,719 on Friday while 1,929 on Thursdays and 1,880 on Wednesday.The government has so far confirmed 40 deaths although unofficial estimates suggest the death toll is much higher.The DGHS said 51,476 people were hospitalised with dengue since January this year. Of them, 43,580 had made full recovery.Currently, 7,856 patients are undergoing treatment at different hospitals and clinics.Bangladesh is grappling with its worst outbreak of dengue. Dhaka, the densely-populated megacity, has been at the centre of the outbreak.There is no specific treatment for dengue or severe dengue, WHO says. But early detection and access to proper medical care lowers fatality rates below one per cent.last_img read more

Can dark energy be explained by symmetrons

This material may not be published, broadcast, rewritten or redistributed in whole or part without the express written permission of Phys.org. “Since GR is very accurate in the laboratory and the solar system (regions in which the density is much higher than the cosmic mean), any fifth force must be ‘screened’ at high densities. The symmetron mechanism is one way to screen fifth forces.”In theory, a symmetron field will mediate a fifth force when its symmetry is broken, which requires a low-density vacuum. In this broken-symmetry phase, the symmetron couples to matter with a certain matter coupling energy. Here, Upadhye investigated the scenario where the matter coupling energy is 1 TeV and the symmetron mass is 10-3 eV. Then he solved the symmetron equations of motion to estimate constraints on the symmetron. Mathematicians offer unified theory of dark matter, dark energy, altering Einstein field equations This symmetron field regime, where the matter coupling energy is 1 TeV, is not only of interest due to its potential to be tested. This energy is also possibly associated with physics beyond the standard model. If this is true, experiments may reveal new effects that indicate new physics. One such experiment is the Eöt-Wash torsion pendulum experiment being carried out by scientists at the University of Washington in Seattle. Upadhye’s calculations allowed him to predict the torque signal that the symmetron would produce in an Eöt-Wash experiment.”It turns out that Eöt-Wash just happens to probe an interesting range of parameters because they have targeted the experiment at the right range of distances,” he said. “Fifth force screening mechanisms are not perfect, so there are residual fifth forces which can be detected by sufficiently sensitive experiments probing the right distances. My paper approximated these residual fifth forces and showed that Eöt-Wash excludes a substantial portion of them.”In this experiment, the presence of a fifth force would cause a metal disk to rotate in such a way as to align with a second metal disk.”Eöt-Wash uses a pair of metal disks with the same pattern of holes in each one,” Upadhye said. “The upper disk is suspended from a wire, allowing it to rotate freely, while the lower disk is rotated at a uniform rate. Fifth forces would cause the upper disk to rotate so as to align its pattern of holes with that on the lower disk. So, by looking for small torques on the upper disk leading to torsional oscillation, Eöt-Wash can search for fifth forces. The experiment can be repeated over a range of separations between upper and lower disks, allowing them to determine the rate at which fifth forces decrease with distance. Since this experiment has been designed to study distances as low as 50 microns, it is very useful for testing fifth forces due to dark energy.”Last December, Upadhye visited the Eöt-Wash group, and the researchers were very interested in testing new dark energy theories. Currently they are designing a new torsion pendulum experiment which should be substantially more sensitive to fifth forces. Upadhye plans to work further on his calculations to allow for more accurate testing.”An approximate treatment such as that in my symmetrons paper is useful for forecasting constraints, but in order to analyze the real data from the upcoming Eöt-Wash experiment, I plan to do more accurate computations of these fifth forces,” Upadhye said. “Several years ago I did such a computation for chameleon fifth forces. I plan to speed up that calculation as well as extend it to symmetron fifth forces. Using the extensive computational resources available here at Argonne, I will analyze Eöt-Wash data and test these dark energy theories.” The Eöt-Wash experiment may test for Upadhye’s predicted torque signal due to the symmetron field. A fifth force could be measured in the submillimeter distance between the two disks. (Left) An illustration of an older model and (right) a photo of a newer instrument. Credit: The Eöt-Wash Group at the University of Washington (Phys.org)—A field that permeates the universe and gives rise to a new force, or “fifth force,” between massive objects may be a candidate for dark energy and an explanation for why the expansion of the universe is accelerating. This field, called the symmetron field, is so named because it has a symmetry in regions of high density, while in regions of low density, such as a vacuum, the symmetry is broken and the field mediates the new force.

Credit: Upadhye. ©2012 American Physical Society Currently, the symmetron concept is purely theoretical. But in a new study, physicist Amol Upadhye at Argonne National Laboratory in Argonne, Illinois, has calculated that a previously unexplored symmetron regime near the dark energy scale will give rise to a fifth force at submillimeter distances. He proposes that short-range gravity experiments can search for the fifth force at these distances and possibly reveal if dark energy is in fact a symmetron field.”Much of my work has focused on chameleon dark energy theories, and I really only started thinking about symmetrons last summer,” Upadhye told Phys.org. “Modern experimental techniques and technologies have advanced enough to search for new physics at distances of interest for dark energy theories.”As Upadhye explained, a symmetron field could fulfill the role of dark energy by acting as a negative pressure.”Dark energy in general can be described by a constant (or slowly varying) vacuum energy density, such as that due to a field whose potential is minimized at a small, positive value,” he said. “In the presence of such an energy density, Einstein’s equation of General Relativity (GR) predicts that the universe will expand at an accelerating rate. In GR, pressure gravitates; positive pressures contribute to the decelerating expansion of the universe. Dark energy acts as a negative pressure which leads to an accelerating expansion.”The simplest model of a dark energy is Einstein’s cosmological constant, a constant vacuum energy density which explains all available data. The big question in cosmology is whether or not the dark energy is just a cosmological constant. Alternative theories predict that the vacuum energy density evolves with time, or that new (‘fifth’) forces exist between known particles. This document is subject to copyright.
