Although they posted only 71 wins in 2014, advanced-stats outlets such as FanGraphs projected Boston to win 90 games, which would have been a 19-win increase — and would have come on the heels of a 26-win decrease, after a 28-win increase, after a 21-win decrease. Boston was shaping up to be on MLB’s craziest roller-coaster ride ever.It didn’t quite work out that way. The Red Sox spent most of 2015 playing just as poorly as they had in 2014, finishing with 78 wins only thanks to a strong push in the season’s final two months, and the fallout was a total front-office shake-up. But more than one-third of the way into the 2016 season, the Red Sox appear to have made the leap that was expected of them a year ago: They have a 34-25 record, are only two games out of first in the American League East, and have a full-season FanGraphs projection of 90 wins. If that last number holds up, Boston’s past five years will once again represent the most up-and-down stretch in modern MLB history: 162003Angels77+22-24+7-12+1516.0 WIN DIFF. IN NO.

Mainly, they’re getting better performances from the lineup. The Red Sox were pretty much a dead-average hitting and fielding team a year ago, which added up to a mediocre record when combined with an unspectacular pitching staff. But this year, no team in the majors — not even the vaunted Chicago Cubs — has gotten more wins above replacement from its position players than Boston, a development headlined by drastic improvements from Xander Bogaerts, Jackie Bradley Jr. and Mookie Betts, a bounce-back season from Dustin Pedroia and the general agelessness of David Ortiz.The Red Sox will probably still spend the summer in a division dogfight with the Baltimore Orioles and Toronto Blue Jays; our power ratings say they’re basically a coin flip (48 percent) to win the East. But even that represents an improvement over the past two seasons and could provide more twists in the roller-coaster track the franchise has been riding. Things are never dull when it comes to baseball in Boston. 201970Mets83+17-27-12+5-1615.6 91994Reds92-19+17-16+17-1617.1 71992Orioles89-22+9+11-33+1317.4 22010Mariners61+24-24+27-10-918.8

Now playing: Watch this: 5 Photos Comments Emails between police and Ring showed tactics the Amazon-owned video doorbell company used to convince officers to join its program. Chris Monroe/CNET Up to 250 police departments have joined Amazon’s Ring Neighbors program, a neighborhood watch app, but these deals don’t happen overnight. For the Chula Vista police department in California, Ring spent more than a year offering discounts and applying peer pressure with constant reminders and emails to convince officers to sign up. The Chula Vista police department signed up for Ring’s Neighbors program in May, but the courtship started in March 2018, according to documents obtained by CNET through a Freedom of Information Act request. The video doorbell company pitched the program to the police department two months before it was publicly announced.These documents detail how Ring’s staff convinced a local police department in California to join Neighbors, an app released by the company in May 2018. When police didn’t respond, Ring would follow up by noting neighboring law enforcement agencies that have joined, pushing for the Chula Vista police to join them.The tactics also offer a window into how Ring, which retail giant Amazon purchased last year for $839 million, has struck partnerships with police departments across the country. Police consider it a tool for obtaining video in investigations, as well as creating surveillance networks in residential neighborhoods. But these relationships are cause for alarm among privacy advocates, who raise concerns that a tech giant like Amazon is helping police create surveillance networks. “A long term goal for CVPD is to have a real-time crime center which will be doing a myriad of things. One of those things would be leveraging civilian surveillance cameras in the city to aid us in solving crime and learning about crime patterns,” CVPD’s community policing Sgt. Frank Giaime said in an email to Ring. “As the crime analysis unit’s capacity increases, I would like to integrate a program like this to help us build a partnership with the community through technology.”Ring didn’t respond to a request for comment.”No, the Chula Vista Police Department did not feel pressured in any way to partner with Ring’s Neighbors app,” the CVPD’s investigations division Capt. Phil Collum said in an email. For the CVPD, the courtship began with a cold pitch. Discounts ringingThe first email from Ring’s outreach coordinator to the Chula Vista police department came in March 2018.The message opened with an introduction and a comment on an increase in crime in the area.”I recently came across this News clip of an uptick in home break-ins in Chula Vista,” the coordinator wrote. “As an extension of Ring’s Neighborhoods initiative, I’m reaching out to share an offer to all public safety agencies that actively participate in either crime prevention or community policing.” He offered to donate a free video doorbell, as well as discounts of up to $50 for more cameras. The email also referenced a Ring pilot program that claimed it reduced crime rates. MIT Technology Review scrutinized that study last October and found that the evidence was flimsy. The Chula Vista police didn’t respond for 10 days, and the outreach coordinator followed up, this time with a flier on different Ring products and a $50 promo code for every officer in the department on video doorbells.CPVD responded and said it would follow up, giving Ring a foot in the door. There’s no email communication between the two until about three months later, in May 2018. The same coordinator said Raymond Pollum, Ring’s head of law enforcement partnerships, would be in the San Diego area demonstrating tools for other police departments.Pollum met with the CVPD department on May 3, 2018, and provided a demonstration of Neighbors and the police dashboard. He followed up with an email four days later and attached a memorandum of understanding “for consideration,” even though CVPD hadn’t agreed to join the program yet.Chula Vista’s police department promoting a Ring giveaway for National Night Out in August. Instagram The police department responded a month later, telling Pollum it sent the proposed contract to higher-ups in June. When he didn’t get a response for another month, Pollum followed up a month later, sending police a link to a crime solved in Tampa, Florida, through Ring’s cameras. CVPD didn’t respond to that message.At the same time, the department was coordinating National Night Out, an annual police-community event for promoting neighborhood safety. Ring was a sponsor for it, and its coordinator promoted contests and giveaways for free video doorbells and discounts at CVPD’s event.”We appreciate the goodies you’re sending and are most interested in having someone man a booth,” Angela Gaines, CVPD’s police community relations officer, told Ring in an email.Ring had brought 20 video doorbell kits for the police community event that August.PressuringThe peer pressure campaign started in January 2019, after surrounding police departments partnered with Ring. Pollum had given the department another demo, and sent the CVPD the memorandum of understanding again on Feb. 1. Giaime told Ring that the department was “eager” to sign the contract but needed to send it off to the chain of command for approval. He told Pollum it would take a few weeks to get a formal presentation together. Four days after Ring’s demonstration, Pollum followed up with another email. “We executed the La Mesa PD MOU yesterday, so they will join Carlsbad PD and Oceanside PD as San Diego LE portal participants,” Pollum wrote. “Not sure if peer pressure is a good thing or not, but wanted to at least make you aware that they are joining the program and will be onboarded shortly.”About three weeks later, on Feb. 21, Pollum followed up and told the sergeant that the La Mesa police department joined Ring, and the San Diego sheriff’s department approved the MOU. Again, Giaime told Pollum he would need a few weeks to put together the presentation and get approval from the command staff. Ring followed up in a month and a half, listing even more police departments that are signing up with the company. “As Chula Vista Police Department considers the benefits of gaining access to the Neighbors Portal, I thought it might be helpful to know of other agencies in the area that have joined,” Pollum wrote on April 2. He listed the San Diego County sheriff’s department, along with police in Oceanside, Carlsbad and La Mesa, and noted that officers in Escondido and National City were considering the program. Six days after that, Ring sent another email to CVPD with the same message. “SD Sheriff’s joined a couple of weeks ago so I’m hoping to get the other major cities in San Diego onboard quickly. Can you give me a quick update on where things stand?” Pollum wrote. Giaime responded with an apology, noting that the police “had a lot of things going on” during that time. He made the presentation to higher-ups on April 26, and four days later, the Chula Vista Police Department signed Ring’s contract, which went into effect on May 1. The department officially announced it joined three months later, on its Instagram page.After a year of emails, discounts and peer pressure from Ring’s executives, CVPD became one of hundreds of police departments to join Ring.

Khandaker Mosharraf HossainBNP senior leader Khandaker Mosharraf Hossain on Sunday said their party thinks the upcoming elections to Rangpur and other city corporations will be an acid test for both the government and the Election Commission ahead of the national election.He said, “We think Rangpur and other city polls are very important as those are going to be held ahead of 11th parliamentary elections.“We’ll closely observe the attitude and activities of the government and the Election Commission during the polls.”The BNP leader came up with the comments while speaking at a discussion arranged by Bangladesh Nagorik Odhikar Forum at the National Press Club, reports UNB.Mosharraf, a BNP standing committee member, said they will go to people to mobilise public support once their chairperson Khaleda Zia presents her election-time government’s formula.Though the government is trying to hold a lopsided election like 2014 one, he said they believe the country’s people will resist such move this time.The BNP leader alleged that government has long been trying to suppress BNP leaders and activists resorting to repressive acts and enforced disappearance.He warned their party, if returns to power, will put those involved in enforced disappearance on trial.Mosharraf said the prime minister Sheikh Hasina’s statement in parliament on enforced disappearance has created confusion among people.“The prime minister admitted that the incidents of enforced disappearance have been taking place in the country. She said such incidents are happening in many other countries. We want to say the enforced disappearance doesn’t take place in any country with state patron using sate machinery. You just gave the reference of other countries only to mislead people. We condemn it,” he said.The BNP leader said there is a huge difference between the incidents of disappearance happening in Bangladesh and other countries. “People are made disappeared in other countries either out of enmity or for ransom. But the administration and the government forces are involved in the incidents in Bangladesh.”Mentioning that the government cannot shirk the responsibility for the incidents of enforced disappearance, he urged the government to take steps to ensure the safe return of those still remained missing in the country.
More information: Tamar Goldzak et al. “Light stops at exceptional points.” Physical Review Letters. DOI: 10.1103/PhysRevLett.120.013901, Also at arXiv:1709.10172 [physics.optics] Light, which travels at a speed of 300,000 km/sec in a vacuum, can be slowed down and even stopped completely by methods that involve trapping the light inside crystals or ultracold clouds of atoms. Now in a new study, researchers have theoretically demonstrated a new way to bring light to a standstill: they show that light stops at “exceptional points,” which are points at which two light modes come together and coalesce, in waveguides that have a certain kind of symmetry. ‘Exceptional points’ give rise to counterintuitive physical effects Explore further Unlike most other methods that are used to stop light, the new method can be tuned to work with a wide range of frequencies and bandwidths, which may offer an important advantage for future slow-light applications.The researchers, Tamar Goldzak and Nimrod Moiseyev at the Technion – Israel Institute of Technology, along with Alexei A. Mailybaev at the Instituto de Matemática Pura e Aplicada (IMPA) in Rio de Janeiro, have published a paper on stopping light at exceptional points in a recent issue of Physical Review Letters.As the researchers explain, exceptional points can be created in waveguides in a straightforward way, by varying the gain/loss parameters so that two light modes coalesce (combine into one mode). Although light stops at these exceptional points, in most systems much of the light is lost at these points. The researchers showed that this problem can be fixed by using waveguides with parity-time (PT) symmetry, since this symmetry ensures that the gain and loss are always balanced. As a result, the light intensity remains constant when the light approaches the exceptional point, eliminating losses.To release the stopped light and accelerate it back up to normal speed, the scientists showed that the gain/loss parameters can simply be reversed. The most important feature of the new method, however, is that the exceptional points can be adjusted to work with any frequency of light, again simply by tuning the gain/loss parameters. The researchers also expect that this method can be used for other types of waves besides light, such as acoustic waves. They plan to further investigate these possibilities in the future.
