The surf, combined with morning high tides near seven feet, was causing minor flooding in low-lying beach areas.High tide at La Jolla was set to be at 7:52 a.m. on Sunday and 8:22 a.m. on Monday, the NWS said.Even larger waves caused damage to the Ocean Beach Pier on Friday morning.A high surf advisory was in effect until 4 a.m. this morning, with waves of seven to 10 feet and sets to 14 feet taking place at beaches in southern San Diego County on Friday.

  • Anthony Weiner Investigation Leads To FBI Back To Clinton Email Server Case

    first_img Share Earlier this year, Comey closed the yearlong investigation without filing any charges against Clinton and her associates.The FBI confirmed to NPR’s Carrie Johnson that the letter to oversight committees went out today, but had no further comment. The Justice Department says it will have no comment either.Two sources familiar with the investigation also told Carrie that the matter does not relate to the WikiLeaks email release, which has been releasing hacked emails from Clinton campaign Chairman John Podesta’s account. The newly discovered emails were not withheld by the Clinton campaign, the sources said, and it was not clear whether Clinton sent or received anything in the new pool of documents.Podesta issued a statement Friday afternoon calling on Comey to release more information about the reopened investigation, especially given its timing in relation to the election: Andrew Harnik/APHillary Clinton boards her campaign plane at Westchester County Airport in White Plains, N.Y., on Friday. The FBI said Friday it will be looking into newly discovered emails related to Clinton’s private server.Updated Newly discovered emails being examined by the FBI in relation to Hillary Clinton’s email server came to light in the course of an unrelated criminal investigation of Anthony Weiner, a source familiar with the matter tells NPR’s Carrie Johnson.Weiner is the estranged husband of close Clinton aide Huma Abedin; he has been under scrutiny for sending illicit text messages to an underage girl.Earlier Friday FBI Director James Comey notified members of Congress that the FBI had reopened its investigation into the handling of classified information in connection with the Democratic presidential candidate’s use of a private email server while secretary of state.In a letter to the leaders of congressional oversight committees, Comey wrote: “In connection with an unrelated case, the FBI has learned of the existence of emails that appear to be pertinent to the investigation. I am writing to inform you that the investigative team briefed me on this yesterday, and I agreed that the FBI should take appropriate investigative steps designed to allow investigators to review these emails to determine whether they contain classified information, as well as to assess their importance to our investigation.”He added, “the FBI cannot yet assess whether or not this material may be significant, and I cannot predict how long it will take us to complete this additional work.” State Department spokesman Mark Toner says his agency has not received a letter from the FBI that he is aware of. He says the department learned of the letter from news reports, per NPR’s Michele Kelemen, and he doesn’t know whether the emails are from her time at State.Republicans quickly took the opportunity to renew criticism of Clinton’s use of a private email server.Donald Trump spoke about the story shortly after it broke at his rally in Manchester, N.H. “Hillary Clinton’s corruption is on a scale we have never seen before,” he said. “We must not let her take her criminal scheme into the Oval Office.”The Republican National Committee said the FBI’s decision ahead of the election “shows how serious this discovery must be” and “raises serious questions about what records may have been turned over and why.”House Speaker Paul Ryan said in a statement that he is renewing his call for the director of national intelligence to suspend classified briefings for Clinton “until this matter is fully resolved.” “FBI Director Comey should immediately provide the American public more information than is contained in the letter he sent to eight Republican committee chairmen. Already, we have seen characterizations that the FBI is ‘reopening’ an investigation but Comey’s words do not match that characterization. Director Comey’s letter refers to emails that have come to light in an unrelated case, but we have no idea what those emails are and the Director himself notes they may not even be significant.“It is extraordinary that we would see something like this just 11 days out from a presidential election.“The Director owes it to the American people to immediately provide the full details of what he is now examining. We are confident this will not produce any conclusions different from the one the FBI reached in July.”last_img read more

  • Pen draws flexible circuits using halfmeter long carbon nanotube fibers

Credit: Huang, et al. ©2015 American Chemical Society In the future, the researchers hope to expand the drawing technique to use different types of ink for different purposes.”We are now working on enabling more functions in the fiber,” Wu said. “For example, one possibility is semiconducting fibers drawn from a pen tip for flexible device applications.” (Phys.org)—While it may look like researchers from Tsinghua University in Beijing are sketching out an idea for a circuit on a piece of paper, they’re actually using a special pen that draws real circuits using carbon-nanotube-based ink.center_img When writing, the pen is lifted off the paper to stretch and suspend the fibers, which can then be laid down on the substrate in the desired position. The researchers demonstrated that complex fiber patterns can be drawn by hand, and they predict that even greater precision can be achieved using advanced mechanical devices.The researchers also showed that increasing the polymer concentration of the ink increases the diameter of the nanotube fibers from 300 nm to 3 µm. In general, thinner fibers have better conductivity than thicker ones due to their better fiber orientation. Tests show that the highly conductive carbon nanotube fibers also exhibit excellent mechanical flexibility. At first, the researchers expected that the ultralong carbon nanotube fibers should maintain their conductivity after bending and distortion. Somewhat surprisingly, their tests showed that the fibers actually exhibit an increase in conductivity after bending—about a 30% increase after 1000 bending cycles. The researchers propose that the stress caused by bending deforms the polymers and improves nanotube alignment, which in turn increases conductivity.

DOI: 10.1021/nl504150a Citation: Pen draws flexible circuits using half-meter long carbon nanotube fibers (2015, February 20) retrieved 18 August 2019 from https://phys.org/news/2015-02-pen-flexible-circuits-half-meter-carbon.html This technique, called “fiber drawing,” has previously been used to construct patterns, but the fiber length is usually very short at just a few millimeters, and the drawing speed is typically very slow. These drawbacks limit its use in circuit fabrication.In the new study, the researchers demonstrated that their new pen can draw carbon nanotube fibers that are more than a half of a meter long with fast drawing speeds of up to 10 cm/second. Their work is published in a recent issue of Nano Letters.Due to the nanotube fibers’ high conductivity and excellent mechanical flexibility, the researchers predict that the fibers could serve as the fundamental building blocks for a wide variety of flexible electronic devices, such as wearable electronics, flexible touch displays, flexible solar cells, RFIDs, and 3D devices.While the pen itself is an ordinary commercial pen, the ink consists of a combination of electrically conductive carbon nanotube fibers and a viscous polymer solution called polyethylene oxide (PEO). The viscous PEO is highly elastic and mechanically strong, which allows it to pull long nanotube fibers from the solution during the writing process. “The drawing technique allow us to achieve very long carbon nanotube fibers mainly due to the high molecular weight of the polymer and high viscosity of the precursor solution as ink,” coauthor Hui Wu, Associate Professor at Tsinghua University, told Phys.org.
