luxmipurA teacher of a primary school had been allegedly molesting a number of children by scaring them at Char Ramani Mohan union of Sadar upazila in Lakhmipur district, reports UNB.The accused teacher is Tofael Ahmed of Masimnagar village of Sadar upazila who was appointed as contractual teacher three years ago at Karatirhat Government Primary School of Char Ramani Mohan union.Earlier on Tuesday, a student informed her parents about the sexual harassment by the teacher and the parents informed it to the school authority. As the news spread several other students also opened up that the teacher also molested them.At least 50 students were victims of molestation, locals said.Meanwhile, Tofael Ahmed fled from the village as the news spread.Upazila education officer Md Moniruzzaman Molla said a three-member team was formed to investigate into the matter.
File Photo of Tofail AhmedAwami League advisory council member Tofail Ahmed MP has come down heavily on leaders of the National Unity Process-led by eminent jurist Kamal Hossain. “People don’t like those who somersaulted in politics and those who don’t have any principle,” said Tofail while addressing a discussion marking 72nd birthday of prime minister Sheikh Hasina on Friday.He said Kamal Hossain became AL MP contesting from Bangabandhu’s constituency. But he left the party and never won any election again, he added.Tofail, also commerce minister, said, “We will see they are (national unity leaders) talking differently after some days.” “How can you call it a national unity while Awami League-led 14-alliance is out of the process?” he asked.He also asserted that no one would be able to foil the national election as it will be held any time before 29 January 2019.AL general secretary Obaidul Quader said, “Communal forces have only one target and that is to remove Sheikh Hasina.”He also said AL would not declare any programme countering BNP.

As of 3:20 p.m. ET, while he was still testifying, Facebook shares were up 4.8%, to $165.52 per share. [UPDATE: Facebook stock closed up 4.5% for the day, to $165.04 per share — a nearly three-week high — with most of the gains coming after the Senate hearing started.]“We didn’t take a broad enough view of our responsibility, and that was a big mistake. It was my mistake, and I’m sorry,” Zuckerberg told the senators in his prepared remarks.What seems to have reassured Wall Street: No real bombshells came out at the Senate hearing at what amounted to political theater. Zuckerberg also countered senators’ questions about whether Facebook should be subjected to tougher new regulations by reiterating that he thinks the discussion should be about “the right regulations.” Popular on Variety After more than a week of prep training, Zuckerberg was succinct and apologetic, and he expressed willingness to follow up to provide additional information. He also acknowledged later, “In retrospect I think we view it as a mistake that we didn’t inform people” when the company learned in 2015 that Cambridge Analytica had improperly obtained the data. In the weeks since the Cambridge Analytica disclosures came out, Zuckerberg — after initially sitting on the sidelines — has apologized and discussed what Facebook is trying to do rectify the situation.Broader markets were already buoyed Tuesday after fears ebbed of a U.S. trade war with China were mitigated by comments from Chinese president Xi Jinping earlier calling for “dialogue” between the two countries rather than “confrontation.”During Tuesday afternoon’s hearing, the senators asked the CEO about a range of topics. Those included its handling of the Cambridge Analytica situation, in which data on up to 87 million users was sold by a third-party researcher to the U.K. political consulting firm; its policies about user privacy; hate speech; and how Facebook is trying to address foreign actors trying to influence elections. A few members of the committee, including Sen. Bill Nelson (D.-Fla.), warned Zuckerberg that Congress may step in to pass new laws governing Facebook’s ability to collect user data but stopped short of explicitly threatening to do that.At one point, asked by Sen. Orrin Hatch (R-Utah) whether Facebook will remain free in perpetuity, Zuckerberg responded, “there will always be a version of Facebook that will be free.” The remark set off speculation that Facebook may be thinking of rolling out an ad-free subscription plan at some point.The joint hearing before the Senate Judiciary and Senate Commerce Committees was scheduled to start at 2:15 p.m. ET, but kicked off around 2:30.
A system of interdependent networks is characterized by the structure (dimension) of the single networks as well as by the coupling between the networks. In random networks with no space restrictions, such as Erdös–Rényi and RR, the connectivity links (blue lines) do not have a deﬁned length. In contrast, in spatially embedded networks nodes are connected only to nodes in their geometrical neighbourhood creating a 2D network, modelled here as a square lattice. The red arrows represent directed dependency relations between nodes in different networks, which can be of different types. a, Coupled lattices. b, A coupled lattice–random network. c, Coupled random networks. d, A real-world spatial network coupled with a random network. Models b and d belong to the same universality class. Credit: Nature Physics (2013) doi:10.1038/nphys2727 New Finnish solution shortens power cuts during storms (Phys.org) —A team of physicists from Israel and the U.S. has discovered that mathematical modeling suggests modern electrical networks may be more vulnerable to cascading collapse than has been previously thought. In their paper published in the journal Nature Physics, the researchers found that previous models that showed such networks to be robust were based on more randomness than is typically found in real-world networks such as the Internet and electrical systems. Modern electrical networks such as those used in the United States have demonstrated a vulnerability to cascading collapse—most famously by the widespread outage that occurred a decade ago taking out power to millions in the northeast and Midwest parts of the country (and parts of Canada). That outage was traced to a series of mistakes that occurred after a software bug caused problems in an alarm system (following some tress falling on power lines) in a single control room. After one small part of the network went down, other parts soon followed, resulting in the largest blackout in U.S. history. Utility representatives insist that technological advances and improvements to the infrastructure have been made which have resulted in a network that is today very unlikely to experience such an outage again. In this new effort, the physicists disagree.The problem with mathematical models that are used to demonstrate how a network might continue working when failures occur, or when they don’t, the team writes, is that they are used to describe networks with nodes randomly spaced. The Internet, they note, and electrical systems are not randomly spaced because of population density differences, geography, etc.—taking out randomness results in orderly lattices that lead to more critical nodes. That in turn, of course, leads to less stable networks.A mathematical model can’t fully describe a real-world electrical grid, of course, and it’s entirely possible that components have been put in place that are able to counteract the lack of randomness in the system currently in use. On the other hand, it’s also possible that such measures have vulnerabilities as well. The researchers suggest utilities add long lines to connect critical nodes to bring the system as a whole back to a more random state to make it more robust.

Above a critical fraction of interdependent nodes, even a single node failure can invoke cascading failures that may abruptly fragment the system, whereas below this critical dependency a failure of a few nodes leads only to a small amount of damage to the system. So far, research has focused on interdependent random networks without space limitations. However, many real systems, such as power grids and the Internet, are not random but are spatially embedded. Here we analytically and numerically study the stability of interdependent spatially embedded networks modelled as lattice networks. Surprisingly, we find that in lattice systems, in contrast to non-embedded systems, there is no critical dependency and any small fraction of interdependent nodes leads to an abrupt collapse. We show that this extreme vulnerability of very weakly coupled lattices is a consequence of the critical exponent describing the percolation transition of a single lattice.

Growing a business sometimes requires thinking outside the box. Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global December 6, 2013 If you’re psyched about Amazon’s scheme to someday have unmanned drones deliver products to your doorstep, scale your excitement back a couple notches. Not only is FAA approval of such a service still a ways off, Amazon’s plan potentially faces one more hurdle: hacker attack drones.As crazy as that might sound, well, just keep reading.”Serial hacker” Samy Kamkar — who was apparently responsible for knocking MySpace offline for a period in 2005 — has created something he calls the SkyJack. It’s an aerial drone that seeks out other drones, hacks them and then essentially takes control over them.Running a combination of custom software and other easily available applications on a Raspberry Pi circuit board, the SkyJack seeks out the wireless signals of nearby drones, hijacks the connections used to control them and commandeer the victims’ flight-control and camera systems, according to a report from Ars Technica.Here, Kamkar explains SkyJack’s technical details:What’s more, Kamkar has made public all the tech specifications that anyone needs to build an aerial hacker drone of their very own.So, imagine all those Amazon drones buzzing overhead being turned into zombies by one rogue drone, and all of our packages winding up in the hands of some criminal. Hopefully delivery drones don’t take to the skies without some serious security measures in place first.What crazy apps and gadgets have you come across lately?
