The suit, filed in U.S. District Court in Beaumont, claims Jones lived in a coed barracks and, after enduring harassment from some of the men in the quarters, was drugged and raped July 28, 2005. Her attackers were Halliburton and KBR firefighters, the suit claims. The petition says the facility was under direct control of the U.S. government, KBR and Halliburton, collectively. Jones’ attorney, L. Todd Kelly, declined to say where Jones was living now because she fears for her safety. He declined to elaborate. Jones’ Web site highlights her nonprofit foundation to help fellow contract workers who may have been sexually assaulted, and displays her “therapeutic” still-life paintings that she offers to paint on commission. The site also mentions a screenplay of her story in Iraq. In a statement, KBR said it couldn’t comment on specifics of the case but that the safety and security of its employees were its top priority. Halliburton says it is improperly named in the matter and expects to be dismissed from the case. “It would be inappropriate for Halliburton to comment on the merits of a matter affecting only the interest of KBR,” the oil-field-services company said in a statement. Rep. Ted Poe, R-Texas, who signed Conyers’ letter, sent his own inquiry to Mukasey on Monday. He said Jones’ father contacted his office after the alleged rape and said his daughter reported KBR/Halliburton was holding her in a shipping container without food and water. Poe said he then contacted the State Department, which dispatched agents to rescue Jones.160Want local news?Sign up for the Localist and stay informed Something went wrong.

KBR has said it was “instructed to cease by government authorities because they were assuming sole responsibility for the criminal investigations.” Justice Department spokesman Peter Carr said Tuesday that the agency was reviewing Conyers’ letter. “The department is investigating this matter, and because it’s an ongoing investigation we are unable to comment further,” Carr said. Jones’ case got renewed attention this week after ABC News previewed a report of the allegations it plans to air on “20/20” next month. Jones began working for KBR as an administrative assistant in 2004 when she was 19, but later transferred to Iraq with another Halliburton subsidiary, according to her lawsuit. HOUSTON – The chairman of the House Judiciary Committee asked the Justice Department on Tuesday to give a full account of its investigation into the alleged rape of a female contract worker in Iraq two years ago. Jamie Leigh Jones, a former Conroe resident, filed a federal lawsuit in May against Halliburton Co., its former subsidiary, KBR Inc., and others, saying she was raped by co-workers while working for a Halliburton subsidiary at Camp Hope, Baghdad, in 2005. The Associated Press usually does not identify people who say they have been sexually assaulted, but Jones’ face and name have been broadcast by ABC News and appear on her own Web site. In a letter dated Tuesday, Rep. John Conyers, D-Mich., asked Attorney General Michael Mukasey whether his office had investigated Jones’ claims and whether the Justice Department has jurisdiction to prosecute under military provisions of the USA Patriot Act.

Proc Natl Acad Sci USA 114:24 6233-6237. Journal information: Proceedings of the National Academy of Sciences “This phenomenon can be considered a lithography-free method that allows for ready fabrication of arrays of nanomaterials, where their size, length, and periodicity could robustly be tuned,” he continues. “Moreover, not only water but other liquids could be used to carry nanomaterials and to induce the wrinkle-to-fold transition.”Moon describes several examples of potential de novo fabrication and analysis techniques, including nanoscale lithography, nanoimprint, growth by chemical vapor deposition, and chemical reaction. “Our method can potentially be used for the fabrication of 1-dimensional nanowires or nanoarrays for application to DNA analysis with very dilute or small amounts of DNA; DNA templates as new metal or ceramic nanostructures; and DNA treatment devices for healing modified DNA. In addition, one can adopt this technique to handle protein, blood, or nanoparticles at nanoscale.”Košmrlj and Stone tell Phys.org that one area of planned research is focused on nonlinear analysis and modeling for improved quantitative understanding of the capillarity-induced wrinkle-to-fold transition. “Since our system is composed of the mechanical behavior of the fold transition triggered by liquid surface tension, the wrinkle-to-fold transition that we’ve found is associated with large deformations where conventional linear elasticity theory does not apply. While the basic mechanisms can be explained within the linear theory, quantitative comparison with experiments can only be achieved by taking into account geometrical and material nonlinearities. We are therefore performing numerical simulations by coupling liquid surface tension and solid deformation, as well as performing analysis with perturbation series, where nonlinearities of elastic structures can be studied systematically.””I also think that the challenges ahead are to find how to achieve larger areas for DNA pattern formation,” Moon says. “In fact, our latest results—obtained after this PNAS article was accepted—shows some impressive progress for the region with wrinkle-to-fold transition in larger areas, such as the entire area underneath a water droplet. Another area to be studied, Moon continues, concerns the fact that biological morphogenesis of skin–substrate systems are ubiquitous in organisms where water is a major constituent. “We’re trying to find situations where our findings are applicable. Active collaborations with experts in the field would be helpful.” The researchers might also investigate materials other than PDMS. “Yes. other polymers can work if they possess the basic factors to govern the fold transition, these being the thinness of the nano-skin and soft body materials, and surface hydrophilicity to ensure sufficient surface reaction with liquid,” Moon notes. Assistant Professor and lead author So Nagashima, Assistant Professor Andrej Košmrlj, Donald R. Dixon ’69 and Elizabeth W. Dixon Professor Howard A. Stone, and Principal Research Scientist Myoung-Woon Moon discussed the paper they and their co-authors published in Proceedings of the National Academy of Sciences. “I think that the most challenging aspect of devising our method for utilizing a thin skin template that responds to water by dynamically changing its surface morphology was finding the conditions where the wrinkle-to-fold transition occurs,” Moon tells Phys.org. “The critical conditions as a function of the applied strain, initial wrinkle geometries, and thickness of the skin layer determined by oxygen plasma treatment duration were difficult to find.” Moon adds that the observation technique for the dynamic transition was limited to only optical microscopes whose highest optical resolution falls between 100 to 1000 nm in the width of nanowires, this being due to the dynamic transition taking place at the submicron scale.When inducing a template surface wrinkle-to-fold transition by exploiting the capillary forces of water containing DNA molecules, Stone points out, the observation that water changes the wrinkle-to-fold transition is new. “As far as we know, ours is the first study to show this effect, as is demonstrating one use of such folds for the alignment of DNA. Moreover, control of surface tension or resultant capillary forces and the area for fold formation is relatively hard—and by adding DNA molecules to water, it appears that the surface tension is changed, so the fold transition length was shorter.”Template preparation used an oxygen plasma treatment of prestretched polydimethylsiloxane (or PDMS, a polymeric organosilicon compound) substrates for varying durations. “In fact,” Moon explains, “the manipulation of PDMS with prestretching strain is a relatively well-developed method as is the oxygen plasma treatment: both have been discussed in the literature. We can make the samples with various sizes of a few millimeters to a few centimeters, which can be also made on much larger area.” Moon notes that the researchers can also vary polydimethylsiloxane’s mechanical properties—to make it more stretchable, soft or flexible—by changing the ratio of elastomer and cross-linker for PDMS preparation.

In addition, Moon adds, smaller substances such as biomolecules or nanoparticles can follow the water channel to form aligned 1-dimensional nanostructures. “Smaller is better. Less is more. We’ve found that the wrinkle-to-fold transition takes place more easily when the following factors become smaller: compression level, skin thickness, droplet volume, size of the sample surface, and static contact angles of droplets.”Based on their findings, the authors stated that their approach could lead to new ways of fabricating functional materials. “Our key finding is that one can change wrinkles into localized folds by simply exploiting the capillary forces of water on wrinkled surfaces under very small strain of about 1% in compression,” Nagashima tells Phys.org. “Recent studies reported in the literature have demonstrated that such wrinkle-to-fold transitions can help develop systems that dynamically change their properties according to the surface morphology. However, inducing the transition in the absence of water is difficult to achieve in practice because, in general, large compression needs to be applied to the skin-substrate system, which hinders wider applications. Our study reveals that even 1% of compression, which is the critical level for creating wrinkles in our case, is large enough to trigger the transition to folds locally when water is present.” Nagashima notes that while the compression level required to induce the transition might differ according to the skin-film system used, only a small compression level would be necessary in combination with water.

Proc Natl Acad Sci USA 114:24 6233-6237. , Science (Phys.org)—Nanowires fashioned from DNA (deoxyribonucleic acid)—one of several type of molecular nanowires incorporating repeating molecular units—are exactly that: Geometrically wire-like DNA-based nanostructures defined variously as having a 1~10 nm (10−9 m) diameter or a length-to-diameter ratio >1000. While nanowires can be made from several organic and inorganic materials, DNA nanowires have been shown to provide a range of valuable applications in programmed self-assembly1,2 of functional materials—including metallic and semiconductor nanowires for use in electronic devices—as well as biological, medical, and genetic analysis applications3,4,5. That being said, DNA nanowire adoption has been limited due to historical limitations in the ability to control their structural parameters—specifically, size, geometry and alignment. Recently, however, scientists at Korea Institute of Science and Technology and Princeton University leveraged the capillary forces of water containing DNA molecules to demonstrate size-controllable straight or undulated aligned DNA nanowires that were spontaneously formed by water entering wrinkled channels of a compressed thin skin on a soft substrate, which subsequently induced a wrinkle-to-fold transition. © 2017 Phys.org This document is subject to copyright.

Its flexible architecture allows easy model deployment across a variety of platforms ranging from desktops to mobile and edge devices. Currently, TensorFlow provides two solutions for deploying machine learning models on mobile devices: TensorFlow Mobile and TensorFlow Lite. TensorFlow Lite is an improved version of TensorFlow Mobile, offering better performance and smaller app size. Additionally, it has very few dependencies as compared to TensorFlow Mobile, so it can be built and hosted on simpler, more constrained device scenarios. TensorFlow Lite also supports hardware acceleration with the Android Neural Networks API. But the catch here is that TensorFlow Lite is currently in developer preview and only has coverage to a limited set of operators. So, to develop production-ready mobile TensorFlow apps, it is recommended to use TensorFlow Mobile. Also, TensorFlow Mobile supports customization to add new operators not supported by TensorFlow Mobile by default, which is a requirement for most of the models of different AI apps. Although TensorFlow Lite is in developer preview, its future releases “will greatly simplify the developer experience of targeting a model for small devices”. It is also likely to replace TensorFlow Mobile, or at least overcome its current limitations. Functionalities Speech recognition Image recognition Object localization Gesture recognition Optical character recognition Translation Text classification Voice synthesis Applications The Alibaba tech team is using TensorFlow Lite to implement and optimize speaker recognition on the client side.
