She had left her wallet and cell phone behind.From the start, Bergman’s family was fearful about what had happened. Her parents, Chris and Kiersten learned on Wednesday, that her body was found in the desert off State Route 85 west of Phoenix.Her father said that investigators used dental records to confirm her identity. Over the last month, Bergman’s parents traveled back and forth to Phoenix, posting flyers, holding vigils and searching for any clues that might lead to her return.She was last seen at her Phoenix home after an argument with her ex-boyfriend. That man, John Clark was later arrested on unrelated charges after police said they found several stolen ID’s in his car.Clark was charged with multiple counts of theft and forgery. Her father said police have not given the family any indication that Clark might be involved in their daughter’s death.Bergman was a graduate of Valhalla High School and had moved to Phoenix earlier this year, to be with Clark. Her family is receiving many messages of love and support on social media. Body of Kiera Bergman, 19-year-old from El Cajon found in Arizona Updated: 10:22 PM Sasha Foo Sasha Foo, FacebookTwitter
In the midst of a fascinating 2008 presidential race, Rolling Stone unveiled its endorsement of Barack Obama last week with this cover. Like anything this race seems to touch, the cover was immediately tagged as controversial (with some cable news pundits suggesting the magazine touched up Obama’s skin color to make him appear “whiter”).Putting that, and Jann Wenner’s politics, aside for a moment, FOLIO: asked some of its friends in the design world to weigh in on the cover. Here are some early returns:NAME: Dan TrombettoTITLE: Art director, FOLIO:CRITIQUE: From a design standpoint, the composition and typography are very straight-forward – nothing very interesting going on there. The use of an Obama illustration portraying him as a glowing savior peering off into an unknown future? It seems a bit melodramatic. But I’m sure it will get some religious folks up in arms and create some controversy, which is probably the desired effect. If nothing else, it sure gives Barack a lot to live up to—especially since “A New Hope” contains no question mark after it.NAME: Marco TurelliTITLE: Art director, Wine EnthusiastCRITIQUE: Doesn’t really do much for me. Coverlines don’t help sell it to the reader. Barack isn’t looking out into the distance nor is he making eye contact, so in effect he isn’t creating a sense of “greater purpose” nor is he connecting with the viewer. I would expect a more provocative coverline like “America’s Only Hope.” I’ve seen much better from RS in the past when covering political figures. They need to get Woodard back. Hillary’s Last Stand could have been fun though.NAME: Paola DiMeglio TITLE: Associate art director, Psychiatric Times CRITIQUE: First reaction was that this looked like something from a Jehovah’s witness “The Watchtower” cover (those brochures that they pass out for a quarter) … has this religious feel to it. It’s more like he’s doing a Superman stance. Maybe they should have put the “S” shirt under his jacket with the cap. That would have gotten the effect, but maybe taken as more of an insult than an endorsement. I don’t really care for the fonts but I see it’s their standard serif font. It looks more like The New Republic or The Week instead of Rolling Stone. NAME: Randy DunbarTITLE: Freelance designerCRITIQUE: Presumably this an illustration. As illustrations go, it’s unremarkable. And Barack appears to have more lines on his face than Georgia O’Keefe. He also appears to be all ear. Personally, I am not inspired by this cover—by design, color, graphics, etc. If this is the “new hope” cover, the future appears to be cloudy … I did check the cover out at the RS Web site and in a smaller version. It has more impact … whatever that means …NAME: Robert SielTITLE: Production director, Sumner Communications CRITIQUE: Very solid cover. I like the painterly touch to the illustration. Nothing really pops out at me about this cover, either great or bad, but it’s solid. The stance of Barack and the one touch of color on the red tie seem to symbolize a Superman pose.NAME: Bryan CanniffTITLE: Owner, Bryan Canniff DesignsCRITIQUE: I have several reservations about this cover. If I were a Barack supporter I would not be too happy about his angry expression. The candidate for change seems to be looking forward to hard times ahead instead of “A New Hope”. He looks so mad he is literally steaming. The blue color scheme is also not very positive. It makes his skin look even redder in contrast (and angrier). I don’t see the need to cover up so much of the logo, unless it is an awkward attempt to say Rollin one. It looks forced since his head is so small and there is no need to show more of his rumpled suit and askew tie. Starting with his pitifully small light yellow name, the typography is very laid back and the layout is too predictable and unexciting.UPDATE: Tim O’Brien, the illustrator behind the Obama cover, responds … What do you think?

Foreign institutional investors (FIIs/FPIs) were bullish on 17 of the 20 trading sessions in July, investing more than $1.57 billion in Indian equities on a net basis though the BSE Sensex gained 3.89 percent during the month.Data gleaned from Central Depository Services (India) Limited, or CSDL, indicates that FIIs were net buyers of Indian equities worth $1,575 million during July, a month that saw many Sensex companies declaring their first quarter (Q1) results, the BJP-led NDA government making forward movement on the Goods and Services (GST) Bill and formally announcing the acceptance of the 7th Central Pay Commission’s recommendations on salary hike benefiting millions of employees.For the first fortnight, FIIs were net buyers of Indian stocks worth $664 million.The Sensex closed 157 points down at 28,051.86 on July 29, still 3.89 percent higher from its June 30 closing of 26,999.72. Triggers for next weekThe first trading day of August is likely to open on a bullish note after the NDA government announced that it will be tabling the much-awaited GST Bill in the Rajya Sabha next week. Going by the statements made both by the government and the Opposition, including the Congress, the landmark indirect tax reform legislation is likely to be passed. The legislation needs a 2/3rd majority, since it is a constitutional amendment Bill.Though a foregone conclusion, the government’s announcement that it will pay salary arrears to about 47 lakh Central government employees in one go along with their August salary is likely to have a positive impact on market sentiments on Monday.Analysts have already said that higher cash in the hands of millions of Indians is likely to spur consumption, enabling companies to scale up production and thereby better utilisation capacities. On the flip side, there is a risk of inflation going up, as has been expressed by Reserve Bank of India (RBI) governor Raghuram Rajan. The week could also see rate-sensitive stocks such as banks and finance companies reacting to speculation of what the RBI says at its August 9 monetary policy review meeting with regard to interest rates, inflation and economic growth, apart from trends in the global economy.During July, many frontline companies such as Infosys, Wipro, TCS and ICICI Bank declared their June quarter results.Monthly volume sales of car, two-wheeler makersThe first trading day of August will be influenced by volume sales data for July to be declared by the likes of Maruti Suzuki, Tata Motors, Mahindra, Bajaj Auto, Hero Motocorp and TVS Motor. Unlisted entities in the sector, including Renault India, Ford, Hyundai, Honda, Toyota Kirloskar and Mercedez, will also be declaring the figures either on Monday or on Tuesday.Maruti Suzuki is likely to post 10.4 percent growth at 1,21,887 units in domestic car sales from 1,10,405 units sold in July 2015, according to analysts Gaurant Dadwal and Vivek Sarin at Nirmal Bang Equities. Bajaj Auto (motorcycle segment) is expected to post 5 percent growth at 2,96,555 units in July 2016 from 2,82,433 units in July 2015, while rival Hero Motocorp sales are likely to come at 5,16,922 units, up 6 percent from 4,87,580 units sold in the corresponding month last year, according to the analysts.Overall, it is expected to be a mixed one for auto makers.”July is a seasonally lean month for automobile sales and hence we don’t expect any big surprise in despatches…In case of two-wheelers, we expect single-digit growth led by higher scooter sales and recent new launches. As regards cars, new models are expected to drive growth for some companies, while in case of commercial vehicles or CVs we expect single-digit YoY growth in medium and heavy commercial vehicles or MHCVs following recent deceleration in sales and a seasonally weak month for CV sales,” the analysts said.
Madrasa girl is undergoing at the hospital. Photo: Ahmed ZayeefThe physicians carried out a surgery on the Feni madrasa girl on Tuesday to make her lungs functional.”We have conducted the operation keeping her on life support,” Brigadier General Nasir Uddin, a director of Dhaka Medical College Hospital (DMCH), told newsmen at the Burn and Plastic Surgery Unit of DMCH on Tuesday.Nasir Uddin said the burned girl is facing a number of complications.Alongside blood and lung infection, she has developed problems in her kidney.He said they were trying to provide the girl the best treatment.”We hope the girl will survive. He requested the countrymen to pray for her,” Nasir Uddin added.Quoting Singapore physicians, he said she could not be taken abroad for treatment in such a critical condition.On Saturday, the student had gone to Sonagazi Islamia Fazil Madrasa to take the Alim examination. She was set on fire after being tricked into going to the roof of the madrasa. On 27 March, the student’s mother filed a case against the principal on charges of sexually abusing her daughter. The student was set on fire as she refused to withdraw the case against the principal. She was admitted to the burn unit of Dhaka Medical College and Hospital in a critical condition.
This picture taken on 15 March, 2019 shows a vehicle as rain, which is believed to be the beginning of Tropical cyclone Idai coming from central Mozambique, falls in the flooded districts of Chikwawaa and Nsanje in southern Malawi. Photo: AFPAt least 31 people have been killed and dozens are missing as tropical cyclone Idai hit eastern parts of Zimbabwe after lashing neighbouring Mozambique, the government said on Saturday.Most of the deaths were in Chimanimani East, Zimbabwe’s information ministry announced on Twitter.Two of the victims were students who died after a landslide sent a boulder crashing into their dormitory, collapsing the wall of the dining room and trapping 50 of them, the country’s Department of Civil Protection (DCP) said in a statement.The boarding school has been shut and the army, which is leading rescue operations, is moving in to take the nearly 200 students to safety.”So far a total of 71 people are reported missing,” said the DCP.Others who had fled their homes were stranded on top of a mountain waiting to be rescued, as strong winds hampered helicopter flights, the ministry said.The storm damaged many houses and washed away bridges in the eastern Manicaland province which borders Mozambique. Thousands of people have been affected by power cuts and flooding, a lawmaker told AFP.Earlier Saturday, Joshua Sacco, an MP in Chimanimani district, told AFP that more than 100 people were missing. Around 100 houses had been swept away in Ngangu township in Chimanimani town, he said.The opposition Movement for Democratic Change called for immediate help for the storm-hit east, warning that a “serious humanitarian crisis” was unfolding there.”We need state intervention on a massive scale to avoid biblical disaster,” MDC spokesman Jacob Mafume wrote on Twitter.President Emmerson Mnangagwa, who is currently on a visit to Abu Dhabi, has declared a state of disaster in the affected areas.- ‘Dire situation’ -Tropical cyclone Idai battered central Mozambique on Friday killing at least 21 people and cutting off more than half a million people in the port city of Beira.Even before the cyclone made landfall on Friday, heavy rains earlier in the week had already claimed 66 lives and forced 17,000 people from their homes in Mozambique, local officials said.They also affected neighbouring Malawi, where 56 people died, the government said.As the cyclone hit, Mozambique’s President Filipe Nyusi appealed for emergency assistance for the victims before leaving for eSwatini.”We have compatriots suffering without hope and we have to restore hope,” he said on Friday as he set off on a three-day state visit to the kingdom previously known as Swaziland.As the cyclone approached, the Red Cross sent out more than 200 volunteers to areas most likely to be affected.”The situation is dire but we don’t know the exact particulars,” said Jamie LeSueur, the Red Cross’s roving emergency operations manager for Africa.He was making the 1,200-kilometre (745-mile) trip from Maputo to Beira by road after flights were cancelled and the airport closed.It would require “the full force of the humanitarian community behind the government of Mozambique to respond to rapidly”, he told AFP.- South Africa rations electricity -Beira’s international airport was closed after the cyclone made landfall, damaging the air traffic control tower, the navigation systems and the runways.”Some runway lights were damaged, the navigation system is damaged, the control tower antennas and the control tower itself are all damaged,” an official at the National Institute of Disaster Management (NIDM) told AFP on Friday.”The runway is full of obstacles and parked aircraft are damaged.”The storm also affected power supplies to neighbouring South Africa which imports electricity from Mozambique to supplement its own production.South Africa’s power utility company Eskom on Saturday introduced electricity rationing “due to the loss of additional capacity, which includes a reduction in imports from Mozambique,” it said in a statement.
Richard Drew/APA member of the FBI Weapons of Mass Destruction team works outside the Time Warner Center, in New York, Wednesday, Oct. 24, 2018. A police bomb squad was sent to CNN’s offices in New York City and the newsroom was evacuated because of a suspicious package.Updated at 5:33 p.m. ETAt least six suspicious packages containing what the FBI called potentially destructive devices have been sent since Monday to several leading Democratic Party figures and to CNN in New York, triggering a massive investigation.Some of the devices “appear to be pipe bombs,” John Miller, New York Police Department deputy commissioner of intelligence and counterterrorism, said at a news conference Wednesday.“The packages are similar in appearance,” the FBI stated, “and contain potentially destructive devices.”Packages were addressed to George Soros, former Secretary of State Hillary Clinton, former President Barack Obama, former CIA Director John Brennan (care of CNN) and former Attorney General Eric Holder. All bore the return address of the office of U.S. Rep. Debbie Wasserman Schultz, the former Democratic National Committee chairwoman.The packages were in manila envelopes with bubble-wrap interior, and the FBI says it is “possible that additional packages were mailed to other locations.”In a statement issued on Wednesday afternoon Wasserman Schultz expressed dismay over her involuntary association with the menacing threats.“This appalling attack on our democracy must be vigorously prosecuted, and I am deeply disturbed by the way my name was used,” she wrote.She confirmed that her offices in Sunrise and Aventura, Fla., were both evacuated “in an abundance of caution.”Also Wednesday, California Democratic Rep. Maxine Waters said U.S. Capitol Police intercepted a suspicious package targeting her office. Waters thanked law enforcement investigating the package and said in a statement, “I unequivocally condemn any and all acts of violence and terror.”“This investigation is of the highest priority for the FBI. We have committed the full strength of the FBI’s resources and, together with our partners on our Joint Terrorism Task Forces, we will continue to work to identify and arrest whoever is responsible for sending these packages,” FBI Director Christopher Wray said in the statement.The Secret Service said Wednesday morning it had intercepted two suspicious packages that were addressed to former Secretary of State Hillary Clinton in Westchester County, N.Y., and former President Barack Obama’s residence in Washington, D.C.The packages addressed to Clinton and Obama contained explosive devices similar to one found Monday at the Bedford, N.Y., home of billionaire George Soros — a frequent contributor to Democratic and progressive causes. An explosive ordnance disposal team did a controlled detonation and destroyed the package.The package sent to CNN, which was addressed to Brennan, contained what “appeared to be a live explosive device” as well as an “envelope containing white powder,” New York City Police Commissioner James O’Neill said at the news conference.The package for Holder “did not reach its intended destination, but was rerouted to the return address in Florida,” the FBI stated.Police in Sunrise said Wednesday morning that they were “working on an investigation of a suspicious package near Sawgrass Corporate Parkway,” which is near the office used by Wasserman Schultz.President Trump, speaking at the White House, said that the “safety of the American people is my highest and absolute priority.”“As we speak, the packages are being inspected by top explosive experts, and a major federal investigation is now underway,” Trump said. “The full weight of our government is being deployed to conduct this investigation and bring those responsible for these despicable acts to justice. We will spare no resources or expense in this effort.”The packages addressed to Clinton and Obama “were immediately identified during routine mail screening procedures as potential explosive devices and were appropriately handled as such,” the Secret Service said in a statement Wednesday. “The protectees did not receive the packages nor were they at risk of receiving them.”The package to Clinton was intercepted late Tuesday, and the package to Obama was intercepted early Wednesday morning.Clinton responded to the incident by saying “We are fine” and thanking the men and women of the Secret Service. Speaking at a Florida fundraiser for Donna Shalala, a former HHS secretary who is running for Congress, she said it is a “troubling time” and that “we have to do everything we can to bring our country together.”The NYPD’s Miller stated that security officials were visiting offices of elected officials and media and television outlets Wednesday to inform them about what to watch for — and, in fact, he says NYPD officials were in the CNN mailroom when the suspicious package was discovered.CNN broadcast images of a yellow mailing envelope addressed to former CIA Director John Brennan and Time Warner Center, also with a return address for Wasserman Schultz in Sunrise, Fla.The explosive device inside was safely removed by the bomb squad using a “bomb truck,” according to Miller, and authorities were working to transport it to FBI laboratories for further investigation, along with the other devices.In a statement, White House press secretary Sarah Sanders said, “We condemn the attempted violent attacks recently made against President Obama, President Clinton, Secretary Clinton, and other public figures.” She added, “These terrorizing acts are despicable, and anyone responsible will be held accountable to the fullest extent of the law.”“These attempted attacks that have been made are beyond criminal, they are acts of pure terror,” said House Majority Whip Steve Scalise, who was shot and gravely wounded during an attack on a baseball practice of Republican lawmakers in 2017. “Violence and terror have no place in our politics or anywhere else in our society.”Like the Clintons, Soros lives in Westchester County, N.Y. The left-leaning philanthropist is the founder of the Open Society Foundations, which works to “build vibrant and tolerant democracies whose governments are accountable to their citizens.” (The OSF has been a financial supporter of NPR.)When the Obamas left the White House, they rented a house in D.C.’s Kalorama neighborhood that they purchased months later. The couple have said they want to remain in Washington, D.C., until their youngest daughter, Sasha, finishes high school.There also were multiple reports of suspicious packages on Wednesday that turned out to be false alarms.Some media outlets had suggested that the White House had received one, but the Secret Service later clarified that “reports of a third intercepted package addressed to the WH are incorrect.”New York Gov. Andrew Cuomo told reporters at Wednesday’s news conference that “a device has been sent to my office in Manhattan, which we were just informed about.” Cuomo’s office later said that “a preliminary investigation on the package at Gov. Cuomo’s office shows it is computer files on the hate group The Proud Boys, who recently appeared in New York.”The downtown San Diego office of The San Diego Union-Tribune was briefly evacuated because of concerns about a possible suspicious package. That was later determined to be a false alarm and police gave the all-clear.This is a breaking news story. As often happens in situations like these, some information reported early may turn out to be inaccurate. We’ll move quickly to correct the record, and we’ll only point to the best information we have at the time.Copyright 2018 NPR. To see more, visit http://www.npr.org/. Share
Schematic of a quantum computation with verification sub-routines. Credit: Nature Physics (2013) doi:10.1038/nphys2763 One of the perplexing puzzles that computer scientists have been struggling with is in figuring out how to prove that results obtained using advanced computers are correct. If a computer is used, for example, to perform a calculation and returns a result that can be had no other way, how can the answer be verified? That question has come up more and more often as scientists move closer to developing true quantum computers—machines that in all likelihood will be able to provide answers to all manner of mysterious questions. But how will we know that the answers they give us, are right?One idea is to create two different types of computers that arrive at answers using completely different architectures, then set them both to work on the same problem to see if they agree. Such a scenario would be the ideal—unfortunately, at this point, it doesn’t appear likely that a new type of architecture capable of keeping up with a quantum computer is likely to come along any time soon, thus, scientists have to look for other options. In this effort by the team in Vienna, the researchers are looking to use a second quantum computer to verify results given by a first, despite being far less powerful.The team used a method known as blind quantum computing to test a single quantum computation by testing the correctness of measurements performed in obtaining the result. Going about it this way means the computer doing the testing, called the verifier, doesn’t have to have the power of the computer being tested, called the server. Quantum blind testing involves using what are known as trap qubits—qubits that are entangled between both of the computers. Verifying (not testing, technically) is done by preparing the trap qubits in a way that is known to the verifier but not the server. Qcloud project to allow online users a taste of quantum computing More information: Experimental verification of quantum computation, Nature Physics (2013) DOI: 10.1038/nphys2763AbstractQuantum computers are expected to offer substantial speed-ups over their classical counterparts and to solve problems intractable for classical computers. Beyond such practical significance, the concept of quantum computation opens up fundamental questions, among them the issue of whether quantum computations can be certified by entities that are inherently unable to compute the results themselves. Here we present the first experimental verification of quantum computation. We show, in theory and experiment, how a verifier with minimal quantum resources can test a significantly more powerful quantum computer. The new verification protocol introduced here uses the framework of blind quantum computing and is independent of the experimental quantum-computation platform used. In our scheme, the verifier is required only to generate single qubits and transmit them to the quantum computer. We experimentally demonstrate this protocol using four photonic qubits and show how the verifier can test the computer’s ability to perform quantum computation.Press release A measurement angle (again unknown to the server) for a trap qubit is chosen which is predetermined by the verifier—allowing it to detect measurement errors (called cheating) by the server. The location of the trap bits are chosen randomly, allowing for calculating the probability of cheating errors by the server at different processing points. The end result is a number that represents the probability that the result given by the more powerful quantum computer is correct. Thus, the method involves testing the way an answer is arrived at, rather than whether the answer is itself actually correct. (Phys.org) —A team of researchers working at the University of Vienna, has developed a technique for verifying results produced by a quantum computer. In their paper published in the journal Nature Physics, the researchers explain how their method uses one simple quantum computer to verify results produced by another that is far more powerful.
