(Phys.org)—Astronomers have recently identified a peculiar bubble-like structure associated with an energetic pulsar known as PSR J1015−5719. The newly found feature, designated G283.1−0.59, is most likely a polar wind nebula. The findings were presented June 9 in a paper published on the arXiv pre-print server. More information: Discovery of a Synchrotron Bubble Associated with PSR J1015-5719, arXiv:1706.02978 [astro-ph.HE] arxiv.org/abs/1706.02978AbstractWe report the discovery of a synchrotron nebula, G283.1-0.59, associated with PSR J1015-5719. Radio observations using the Molonglo Observatory Synthesis Telescope and the Australia Telescope Compact Array at 36, 16, 6, and 3 cm reveal a complex morphology. The pulsar is embedded in the “head” of the nebula with fan-shaped diffuse emission. This is connected to a circular bubble of 20″ radius and a collimated tail extending over 1′. Polarization measurements show a highly ordered magnetic field in the nebula. It wraps around the edge of the head and shows an azimuthal configuration near the pulsar, then switches direction quasi-periodically near the bubble and in the tail. Together with the flat radio spectrum observed, we suggest that this system is most plausibly a pulsar wind nebula (PWN), with the head as a bow shock that has a low Mach number and the bubble as a shell expanding in a dense environment. The bubble could act as a magnetic bottle trapping the relativistic particles. A comparison with other bow-shock PWNe with higher Mach numbers shows similar structure and B-field geometry, implying that pulsar velocity may not be the most critical factor in determining the properties of these systems. We also derive analytic expressions for the projected standoff distance and shape of an inclined bow shock. It is found that the projected distance is always larger than the true distance in three dimensions. On the other hand, the projected shape is not sensitive to the inclination after rescaling with the projected standoff distance. © 2017 Phys.org Explore further This document is subject to copyright.

Located some 16,600 light years away from the Earth, PSR J1015−5719 is an energetic pulsar with a spin period of 0.14 seconds and an estimated age of about 39,000 years. The pulsar was detected in 2003 by the Parkes Multibeam Pulsar Survey. Although PSR J1015−5719 is located near the gamma-ray source 3EG J1014−5705, so far no pulsed or persistent gamma-ray emission has been found at the pulsar position. Therefore, the possibility of association with this source was excluded by researchers. Moreover, follow-up infrared, optical, and X-ray observations also found no counterparts to this pulsar.Now, a team of astronomers led by C.-Y. Ng of the University of Hong Kong presents the results of new radio observations of PSR J1015−5719, which reveal an interesting structure associated with this pulsar. The observational campaign was conducted using the Molonglo Observatory Synthesis Telescope (MOST) and the Australia Telescope Compact Array (ATCA), both located in Australia. The new data allowed the researchers to reveal a nebula consisting of a diffuse head, a circular bubble, and a collimated tail.”We report the discovery of a synchrotron nebula, G283.1−0.59, associated with PSR J1015−5719. Radio observations using the Molonglo Observatory Synthesis Telescope and the Australia Telescope Compact Array at 36, 16, 6, and 3 cm reveal a complex morphology. The pulsar is embedded in the ‘head’ of the nebula with fan-shaped diffuse emission. This is connected to a circular bubble of 20″ radius and a collimated tail extending over 1′,” the scientists wrote in the paper.According to the authors of the study, G283.1−0.59 is most likely a bow-shock pulsar wind nebula (PWN). PWNe are characterized by broadband synchrotron radiation from radio to X-ray bands when they are formed as a result of interaction of pulsar wind with the ambient medium. The morphology of bow-shock PWNe includes a long collimated tail with a small bow-shock standoff distance.The team revealed that morphology of G283.1−0.59’s head resembles the shape of a classical bow shock. The results also suggest a projected stand-off distance of about 20″. Therefore, the researchers argue that the morphology of the newly discovered nebula is similar to that of other PWNe.The hypothesis that G283.1−0.59 is associated with and thus powered by PSR J1015−5719 is based on the fact that the nebula is very close in projection to the pulsar.”We suggest that this is a newly identified bow-shock PWN associated with J1015. (…) Given its peculiar properties, a chance coincidence seems very unlikely,” the paper reads.The astronomers concluded that G283.1−0.59 is an interesting rare example of a slow moving bow-shock PWN, in which the pulsar spin axis misaligns with the proper motion direction.
Pratha Parv – a festival of folk, tribal and traditional cultural expressions of India is being presented by Sangeet Natak Akademi, a national academy of music, dance and drama and an autonomous body under the Ministry of Culture, Government of India.In a country as vast and layered with history, antiquity and diversity, it is the realm of performing arts in which a deep connection of various genres of art or skill can be seen weaving a continuity of expressions. Also Read – Add new books to your shelfTraditional cultural expressions also called ‘expressions of folklore’ may include music, dance, art, designs, names, signs and symbols, performances, ceremonies, architectural forms, handicrafts and narratives, or many other artistic or cultural expressions including the folk and tribal art. These, which essentially form parts of the identity and heritage of a traditional or indigenous community, are passed down from generation to generation, and are integral to the cultural and social identities of indigenous and local communities. They transmit core values and beliefs. And primarily, these notions are constantly developing and being recreated within the community ie the practitioners and connoisseurs and passed on to new generations as future protectors of the shared legacy. Also Read – Over 2 hours screen time daily will make your kids impulsiveThe festival comprises presentations of diverse forms of performing arts, film screenings sourced from the meticulously cultivated archives of the Akademi exhibition and dissemination of various musical instruments, folk and traditional, from different states of the country (primarily North-East, Odisha, Kerala and Uttarakhand). The programme also includes interactive session with artists who will share their traditional methodologies and other related aspects that may bring forth the tangible and intangible aspects to incorporate verbal expressions or symbols (stories, epics, legends, tales, riddles), musical expressions (songs, instrumental music), expressions by action (dance form, play, ritual), tangible expressions (drawings, designs, paintings, body art, carvings, woodwork, metal work, jewellery, glassware, textiles, costumes) and intangible expressions reflecting traditional forms of thought and architectural forms. The festival is an opportunity to bringing into limelight and assimilating a variety of cultural aspects of the country, as defined as North, South, East, and West and the resplendent North-East. Each day of the festival is based on this cultural classification, which aims to enhance and safeguard the inherent plurality of the cultural identity that this country so strongly identifies with.
Researchers at MIT have come up with an intriguing approach to combat ‘Glioblastoma’- a malignant tumor of the brain/spinal cord- using machine learning techniques. By reducing the toxic chemotherapy and radiotherapy that is involved in treating this cancer, the researchers aim to improve the quality of life for patients, while also reducing the various side effects caused by the former using Reinforcement learning techniques. While the prognosis for adults is no more than 5 years, medical professionals try to shrink the tumor by administering drug doses in safe amounts. However, the pharmaceuticals are so strong that patients end up suffering from their side effects. Enter Machine Learning and Artificial Intelligence to save the day. While it’s no hidden truth that machine learning is being incorporated into healthcare on a huge scale, the MIT researchers have taken this to the next level. Using Reinforcement Learning as the Big Idea to train the model Media Lab researcher Gregory Yauney will be presenting a paper next week at the 2018 Machine Learning for Healthcare conference at Stanford University. This paper details how the MIT Media Lab researchers have come up with a model that could make dosing cycles less toxic but still effective. Incorporating a “self-learning” machine-learning technique, the model studies treatment regimens being used presently, and iteratively changes the measurements. In the end, it finds an ideal treatment design suited to the patient. This has proven to reduce the tumor sizes to a degree almost identical to that of original medical regimens. The model simulated trials of 50 patients and designed treatments that either reduced dosages to twice a year or skipped them all together. This was done keeping in mind that the model has to shrink the size of the tumor but at the same time ensuring that reduced dosages did not lead to harmful side effects. The model is designed to used reinforced learning (RL)- that comprises artificially intelligent “agents” that complete “actions” in an unpredictable, complex environment to reach the desired outcome. The model’s agent goes through traditionally administered regimens. It uses a combination of the drugs temozolomide (TMZ) and procarbazine, lomustine, and vincristine (PVC), administered to the patients over weeks or months. These regimens are based on protocols that have been used clinically for ages and are based on both, animal testing and various clinical tests and scenarios. The protocols are then used by Oncologists to predict how many doses the patients have to be administered based on weight. As the model explores the regimen, it decides on one of the two actions- Initiate a dose Withhold a dose If it does administer a dose, it has to make the decision if the patient needs the entire dose, or only a portion. After a decision is taken, the model checks with another clinical model to see if the tumor’s size has changed or if it’s still the same. If the tumor’s size has reduced, the model receives a reward else it is penalised. Rewards and penalties essentially are positive and negative numbers, say +1 or – 1. The researchers also had to ensure that the model does not over-dose or give out the maximum number of doses to reduce the mean diameter of the tumor. Therefore, the model is programmed in such a way that whenever it chooses to administer all full doses, it gets penalized. Thus the model is forced to administer fewer, smaller doses. Patik Shah, a principal investigator at the Media Lab who supervised this research, further stresses on the fact that, as compared to traditional RL models that work toward a single outcome, such as winning a game, and take any and all actions that maximize that outcome, the model implemented by the MIT researchers is a “unorthodox RL model that weighs potential negative consequences of actions (doses) against an outcome (tumor reduction)” The model is strikingly wired to find a dose that does not necessarily maximize tumor reduction, but also establishes a perfect balance between maximum tumor reduction and low toxicity for the patients. The training and testing methodology used The model was trained on 50 simulated patients – randomly selected from a large database of glioblastoma patients. These patients had previously undergone traditional treatments. The model conducted about 20,000 trial-and-error test runs for every patient. Once training was complete, the model understood the parameters for optimal regimens. The model was then tested on 50 new simulated patients and used the above-learned parameters to formulate new regimens based on various constraints that the researchers provided. The models treatment regimen was compared to the results of a conventional regimen using both TMZ and PVC. The outcome obtained was practically similar to the results obtained after the human counterparts administered treatments. The model was also able to treat each patient individually, as well as in a single cohort, and achieved similar results (medical data for each patient was available to the researchers). In short, the model has helped to generate precision medicine-based treatments by conducting one-person trials using unorthodox machine-learning architectures.Nicholas J. Schork, a professor and director of human biology at the J. Craig Venter Institute, and an expert in clinical trial design explains “Humans don’t have the in-depth perception that a machine looking at tons of data has, so the human process is slow, tedious, and inexact,” he further adds “Here, you’re just letting a computer look for patterns in the data, which would take forever for a human to sift through, and use those patterns to find optimal doses.” To sum it all up, Machine learning is again proving to be an essential asset in the medical field- helping both researchers as well as patients to view medical treatments in an all new perspective.
