Waze turning road warriors into map builders Citation: Data from savvy cabbies to help improve online mapping (2010, November 8) retrieved 18 August 2019 from https://phys.org/news/2010-11-savvy-cabbies-online.html Microsoft Research Asia engineers are analyzing three months’ worth of data from GPS units installed in more than 33,000 taxi cabs in Beijing in the hope of identifying the short cuts and side streets frequented by drivers who know the best routes to take at any given time. To do the analysis, they designed a software program dubbed “T-Drive” to merge with satellite map information. Team leader Yu Zheng says the system outperforms the estimates provided by online mappers such as Google, Mapquest, and Bing, which use data on speed limits and the length of the road. These mapping systems can rarely help drivers select short cuts or routes around traffic light delays or jams.Over 60 percent of T-Drive’s routes were faster than those provided by Google or Bing, and at least half of these results were 20 percent faster or better, giving an overall saving of 16 percent off the duration of the trip. This is equivalent to shaving an average of five minutes off per 30 minutes of traveling. A web-based user interface of T-Drive. Image credit: Microsoft Research.

Other systems are also being worked on, including a collaborative approach by Nokia and the University of California, which uses GPS information from motorists’ mobile phones. Another system, from Silicon Valley company, Waze, allows drivers to share their real-time routes with online social networks to help other drivers adjust their routes to the current traffic conditions. Waze co-founder, Ehud Shabtai, said the Beijing approach makes sense, saying “you can probably assume routes taxi drivers take are more optimal,” and the best short cuts may not be known to less savvy drivers. Faster routes are also not always the shortest on the map, he said.The T-Drive findings are being presented this week in San Jose, California at the International Conference on Advances in Geographic Information Systems. — T-Drive: research.microsoft.com/apps/pu … fault.aspx?id=138985– IEEE research paper (PDF): research.microsoft.com/pubs/13 … driver-demo-IEEE.pdf Application scenario of T-Drive.

El Niño, is of course, a non-seasonal change of weather patterns in different parts of the world—all connected to a change in upper sea level temperatures along the equator. Warm water from below is pushed up, causing sea temperatures near the surface to be abnormally high as it moves towards the Americas. The result is generally more rainfall on the western coasts of North and South America as trade winds carry the moisture to land and droughts in other places such as Australia and Indonesia. By deploying an array of floating temperature sensors throughout the pertinent part of the ocean, scientists have been able to predict with a high degree of accuracy when an El Niño will occur—for up to six months. In this new effort, the researchers claim that using only atmospheric air temperature readings above the Pacific and the Equator, they are able to predict an El Niño up to a year in advance.The new technique is based on data and analysis of patterns that link air temperatures over the ocean at the equator with temperatures over the rest of the Pacific Ocean. Their analysis showed that when the two temperature readings are closely linked, the odds of an El Niño go up—enough to allow for relative percentages to be calculated. Their data shows, they say, that that for the year coming up, 2014-2015, there is a 75 percent chance of an El Niño occurring.Other researchers thus far aren’t as confident of the team’s results—they suggest that the limited amount of data the researchers had available to them means their predictions are premature. Others contend that it’s just not possible to predict such a complicated weather event using such a simplistic approach. For this coming year, it may not matter, as most other climatologist using conventional methods are also predicting this will be an El Niño year as well. (Phys.org) —An international team of researchers has ignited a controversy over their claim to be able to predict El Niño up to a year in advance. In their paper published in Proceedings of the National Academy of Sciences, the team claims their method, which relies solely on atmospheric temperature readings, accurately predicted the last two El Niño years.

Despite its importance, conventional forecasting is still limited to 6 mo ahead. Recently, we developed an approach based on network analysis, which allows projection of an El Niño event about 1 y ahead. Here we show that our method correctly predicted the absence of El Niño events in 2012 and 2013 and now announce that our approach indicated (in September 2013 already) the return of El Niño in late 2014 with a 3-in-4 likelihood. We also discuss the relevance of the next El Niño to the question of global warming and the present hiatus in the global mean surface temperature. © 2014 Phys.org The 1997 El Nino seen by TOPEX/Poseidon.

(Phys.org)—An international team of astronomers has detected a new slowly evolving Type Ibn supernova as part of the Optical Gravitational Lensing Experiment (OGLE). The new event, designated OGLE-2014-SN-131, has the longest rise time ever observed in Type Ibn supernovae. The discovery is described in a paper published Mar. 23 on the arXiv pre-print server. Type Ibn supernovae are explosions whose spectra are characterized by low-velocity helium emission lines. They are thought to be the core-collapse explosions of massive stars whose ejecta interact with helium-rich circumstellar material. They have also relatively high peak luminosities and are blue at peak.Type Ibn supernovae are usually fast evolving with a short rise to peak brightness (less than two weeks) and a subsequent fast decline. However, a group of researchers led by Emir Karamehmetoglu of the Stockholm University in Sweden has found a new Type Ibn supernova that exhibits an unprecedentedly long rise time and a much broader light curve compared to other supernovae in this class.Karamehmetoglu’s team discovered OGLE-2014-SN-131 on November 11, 2014 using the OGLE-IV Transient Detection System. Afterward, the researchers conducted follow-up photometric observations of this supernova with the OGLE telescope at the Las Campanas Observatory in Chile and with the Gamma-Ray Burst Optical/Near-Infrared Detector (GROND) mounted on the 2.2m MPG/ESO telescope at La Silla, also in Chile. Moreover, they performed spectroscopic observations of OGLE-2014-SN-131 with the ESO New Technology Telescope (NTT) at La Silla and with the Very Large Telescope (VLT) at Cerro Paranal in Chile.These observations show that OGLE-2014-SN-131 spectroscopically resembles other Type Ibn supernovae such as SN 2010al and showcases also peak luminosity and post-peak colors similar to other events in this class. Notably, however, the light curve of OGLE-2014-SN-131 is broader and longer-rising than any other Type Ibn supernova.”Spectroscopy and multi-band photometry of OGLE14-131 have been presented. Identification of prominent He I emission lines classifies this SN as a Type Ibn. While, spectroscopically, OGLE14-131 is identified as a normal SN Ibn, when compared to other Type Ibn SNe, its broad light curve shows the longest rise time ever observed for this SN class,” the authors write.The researchers try to explain this record-long rise time, noting that it requires higher ejecta and circumstellar material masses for the progenitor when compared to typical supernova Ibn progenitors. Therefore, they concluded that the most likely progenitor scenario for OGLE-2014-SN-131 is a massive Wolf–Rayet star.”To explain the unusually long rise time, the broad light curve, the light curve decline, and the spectra characterized by narrow emission lines, we favor a powering mechanism where the SN ejecta are interacting with a dense curcumstellar material. The progenitor of OGLE-2014-SN-131 was likely a Wolf-Rayet star with a mass greater than that of a typical SN Ibn progenitor, which expelled the circumstellar material that the SN is interacting with,” the team wrote in the paper.The astronomers added that given the fact that OGLE-2014-SN-131 has an unusually massive progenitor for a Type Ibn supernova, we should expect a low number of similar slowly evolving events as such massive stars should be relatively rare. Astronomers discover new gas giant exoplanet More information: OGLE-2014-SN-131: A long-rising Type Ibn supernova from a massive progenitor, arXiv:1703.08222 [astro-ph.HE] arxiv.org/abs/1703.08222AbstractType Ibn supernovae (SNe Ibn) are thought to be the core-collapse explosions of massive stars whose ejecta interact with He-rich circumstellar material (CSM). We report the discovery of a SN Ibn, with the longest rise-time ever observed, OGLE-2014-SN-131. We discuss the potential powering mechanisms and the progenitor nature of this peculiar stripped-envelope (SE), circumstellar-interacting SN. Optical photometry and spectroscopy were obtained with multiple telescopes including VLT, NTT, and GROND. We compare light curves and spectra with those of other known SNe Ibn and Ibc. CSM velocities are derived from the spectral analysis. The SN light curve is modeled under different assumptions about its powering mechanism (56Ni decay, CSM-interaction, magnetar) in order to estimate the SN progenitor parameters. OGLE-2014-SN-131 spectroscopically resembles SNe Ibn such as SN 2010al. Its peak luminosity and post-peak colors are also similar to those of other SNe Ibn. However, it shows an unprecedentedly long rise-time and a much broader light curve compared to other SNe Ibn. Its bolometric light curve can be reproduced by magnetar and CSM-interaction models, but not by a 56Ni-decay powering model. To explain the unusually long rise-time, the broad light curve, the light curve decline, and the spectra characterized by narrow emission lines, we favor a powering mechanism where the SN ejecta are interacting with a dense CSM. The progenitor of OGLE-2014-SN-131 was likely a Wolf-Rayet star with a mass greater than that of a typical SN Ibn progenitor, which expelled the CSM that the SN is interacting with.

Explore further What if the government of a country, such as the United States, releases glowing economic reports, but fails to include companion documents that outline how happy its residence are? Graham, Laffan and Pinto point out that judging the health of a country by its economic numbers alone does not give a true picture. For example, GDP numbers for the U.S. are currently high, while unemployment numbers are very low. Things must be good, right? If that is the case, why is the country experiencing such a high suicide rate? And why is life expectancy falling? They suggest that national economic reports need to be updated to include a well-being index (as opposed to the notorious misery index once proposed by economist Arthur Okun.) Including such an index would not be a flight of fancy, they note, it would offer policymakers a better frame of reference, or perhaps a warning light. If the powerhouse countries of the world had such an index, perhaps the global economic crises that started in 2008 could have been averted. They suggest that adding measures such as a well-being index is necessary for long-term sustainability.The authors also note that well-being metrics have a come a long way over the past few decades and can offer policy-makers statistics at virtually every level of a society. They can also offer lawmakers pertinent information about social issues, which could come in handy during election cycles. They point out that economic indicators now present a paradox—some numbers may show prosperity while others indicate something wildly different is going on. They suggest a well-being index could be a tool that helps to resolve such inconsistencies and note that some countries such as Bhutan have already climbed on board—officials there carry out a survey every five years to test the mood of the country. And the U.K. has been measuring national happiness since 2011. They suggest others follow the lead.

Both were built by Neolithic people thousands of years ago. One site, called Tulán-54 is believed to be older than the second—perhaps as old as 5000 years. The second site, named Tulán-52 is believed to have been used from approximately 1110-900 BC until 550-360 BC. Excavation for the first was completed in 1985—the second was finished in 2015. After much study, researchers working on the excavations concluded that the complexes were semi-sedentary settlements—people both lived in them and used them for ceremonies. In this new effort, the researchers suggest that neither site was ever used as a place to live. They note that both complexes show many signs of being used for rituals but lack signs of settlement. Gold-plated vulture heads have been found, for example, along with mortars and grinding slabs that were used to prepare pigments, and plants that contain hallucinogens. Also, the remains of more than two dozen infants were found.In studying the complexes and the artifacts, the researchers found more similarities between the two than found in prior studies—similarities that suggested more complexity than had been realized before. They suggest that the layout of Tulán-54 and its artifacts indicate that the site was like a fully developed ceremonial center. The way the stones were used to build the complex is one example suggesting a massive concerted effort.The researchers also suggest that innovations that occurred in the second site, such as using camelids to carry material to the site, the use of farming to feed the people, and plant processing to produce hallucinogen effects and metallurgy, all point to a ceremonial purpose—though they suggest it is still not clear what the ceremonies were for. A pair of researchers has found evidence at the Tulán-52 excavation in Chile that suggests the need for a reinterpretation of how the stone complex was used. In their paper published in the journal Antiquity, Lautaro Núñez with Universidad Católica del Norte and Catherine Perlès with Allée de l’Université, suggest the new evidence shows more social complexity among the later hunter-gatherers who built and used the complex than previously thought.
Gilbert Carrasquillo by NPR News Bobby Allyn 8.27.19 4:54pm Twelve years after Meek Mill was arrested as a 19-year-old in North Philadelphia on gun and drug charges, his criminal case has officially ended. On Tuesday, Meek pleaded guilty to a misdemeanor firearm charge in Philadelphia. Prosecutors then dismissed all remaining counts against him and the judge imposed no further penalty. The drug and gun case against Meek, whose legal name is Robert Rihmeek Williams, has been active since his 2007 arrest, keeping the hip-hop artist on probation for nearly his entire adult life.”Meek free! I’m not on probation no more,” Meek said to a cheering crowd outside of the courthouse in Philadelphia’s Center City. “I just wanted to come up here and thank all the supporters, because I know y’all probably have family members in jail or people going through the same thing as me. I will continue to do what I do with the reform movement and help the people that help me.” For years, Meek, now 32, clashed with a Philadelphia trial judge Genece Brinkley, who oversaw his case and accused the rapper of not following the rules of his probation, prompting Brinkley to repeatedly scold Mill. In November 2017, Brinkley sentenced Meek to two-to-four years in state prison over probation violations involving riding a dirt bike in New York and his role in an alleged scuffle in the St. Louis airport. This decision turned Meek’s case into a lightning rod for criminal justice reform.While behind bars, celebrity backers of Meek, including Jay-Z, T.I. and Kevin Hart, wrote high-profile op-eds, addressed supporters at rallies and voiced support on social media to highlight what they see as an unjust sentence emblematic of systemic inequities in America’s prison system. Meek, who grew up in Strawberry Mansion, North Philadelphia, also had the support of many Philadelphians throughout his legal saga. During his dozens of court hearings, neighborhood friends and fans would pack the courtroom in support of his release. Throughout this legal battle, Meek has stayed consistent with his musical output, dropping his most recent studio album, Championships, in Nov. 2018, which debuted No. 1 on the U.S. Billboard 200. After serving five months of his sentence, a Pennsylvania appeals court released Meek from prison and granted him bail in April 2018. The appeals court later removed Brinkley from the case and granted the rapper a re-trial due, in large part, to the fact that the only witness who testified against Meek in his original case was a police officer who was later found of lying and theft. Just before his conviction was tossed by the appeals court in July, Meek and Jay-Z were announced as co-chairs of the criminal justice reform organization REFORM Alliance that, to date, has claimed to have raised $50 million dedicated to “changing the laws, policies and practices that perpetuate injustice,” starting with probation and parole.Philadelphia District Attorney Larry Krasner released a statement on the news of Meek’s case being dropped today, saying that the rapper “was unfairly treated in a case that exemplifies the destruction caused by excessive supervision, instances of corruption, and unfair processes in our criminal courts.” Krasner went on to say that Meek has “demonstrated significant rehabilitation; he has evolved and grown” since his initial arrest more than a decade ago. Meek took to Twitter to underscore his commitment to working as a criminal justice reformer. “I’m extremely grateful that my long legal battle is finally behind me and I appreciate that it has sparked a much-needed discussion about probation reform and the inequalities that exist within our two Americas,” he posted.Copyright 2019 NPR.

A pen is mightier than the sword, and who would agree more than Amit Dahiyabadshah, ideator of the movement called Delhi Poetree Association which encourages and nurtures all budding poets across different walks of life.‘DelhiPoetree is a movement with three measurable objectives apart from the love for poetry- First to promote the hosting of 30 poetry readings across the National Capital region of Delhi every month. Second, to honour 100 contemporary poets as the living treasure of Delhi and to obtain this honour from the government, society at large and the local community of the poet including his/her neighbourhood and to facilitate 100 poets to earn a taxable income from poetry alone by the year 2018,’ says Amit. Also Read – ‘Playing Jojo was emotionally exhausting’Divided into two major parts called Dilli Kavita Kumbh and The Thousand Poets Reading, the association believes that poetry can save society and revive the sense of community.‘Many people mistakenly call Delhi Poetree a club or a group. It isn’t some society, it’s a movement aimed to bring about a revolution through words and not blood,’ he adds.Speaking about its reach, Delhi Poetree is widely recognised and respected as the most active poetry movement now. Its regular well organised readings feature poets in the age groups 6 to 93 and so does its audience that gathers regularly to witness a wide range of poetry for all age groups. Also Read – Leslie doing new comedy special with NetflixDelhi Poetree has featured over 1300 poets in the last 9 years since its advent in 2003 and is touted as the biggest poetry event of its kind now.‘We are looking for original talent in the city. Everyone is welcome to visit and read out their poetry. Refine the crude and rootless population of the city, identify and edify their latent poetic talent and, finally, help them get published and sold. Besides the fact that there is no other open platform for original poetry in Delhi, the Poetree also brings together enthusiasts and gives everyone a chance to shine,’ Dahiyabadshah says. Agrees Manu Sharma, a regular at such events: ‘Poetry is the next big thing and forums like these give a platform for like minded people to reconnect and share their thoughts.’‘I narrated a self creation titled ‘Suno Krantiveer’ which was a satire on three most well known aspects of life which are abused the most- love, religion and revolution.Today everyone wishes to revolutionise the world, be it the Kejriwals or the Moists. But deep down no one really cares for the universal good rather have their own vested interests mostly about aquiring power. My poetry intends to aware people and educate rather than titillate,’ Manu signs off.
