EXTP is a science mission designed to study the state of matter under extreme conditions of density, gravity and magnetism. Primary goals are the determination of the equation of state of matter at supra-nuclear density, the measurement of QED effects in highly magnetized star, and the study of accretion in the strong-field regime of gravity. Primary targets include isolated and binary neutron stars, strong magnetic field systems like magnetars, and stellar-mass and supermassive black holes. The mission carries a unique and unprecedented suite of state-of-the-art scientific instruments enabling for the first time ever the simultaneous spectral-timing-polarimetry studies of cosmic sources in the energy range from 0.5-30 keV (and beyond). Key elements of the payload are: the Spectroscopic Focusing Array (SFA) - a set of 11 X-ray optics for a total effective area of ∼0.9 m2 and 0.6 m2 at 2 keV and 6 keV respectively, equipped with Silicon Drift Detectors offering 2, between 6 and 10 keV, and spectral resolution better than 250 eV;the Polarimetry Focusing Array (PFA) - a set of 2 X-ray telescope, for a total effective area of 250 cm2 at 2 keV, equipped with imaging gas pixel photoelectric polarimeters;the Wide Field Monitor (WFM) - a set of 3 coded mask wide field units, equipped with position-sensitive Silicon Drift Detectors, each covering a 90 degrees × 90 degrees field of view. The eXTP international consortium includes major institutions of the Chinese Academy of sciences and Universities in China, as well as major institutions in several European countries and the United States. The predecessor of eXTP, the XTP mission concept, has been selected and funded as one of the so-called background missions in the Strategic Priority Space science program of the Chinese Academy of sciences since 2011. The strong European participation has significantly enhanced the scientific capabilities of eXTP. The planned launch date of the mission is earlier than 2025. © 2016 SPIE.

Chemical pressure tuning of URu2Si2 via isoelectronic substitution of Ru with Fe

Physical Review B 2015年第8期91卷 085122-085122页

We have used specific heat and neutron diffraction measurements on single crystals of URu2−xFexSi2 for Fe concentrations x≤0.7 to establish that chemical substitution of Ru with Fe acts as “chemical pressure” Pch as previously proposed by Kanchanavatee et al. [Phys. Rev. B 84, 245122 (2011)] based on bulk measurements on polycrystalline samples. Notably, neutron diffraction reveals a sharp increase of the uranium magnetic moment at x=0.1, reminiscent of the behavior at the “hidden order” to large-moment-antiferromagnetic phase transition observed at a pressure Px≈0.5−0.7 GPa in URu2Si2. Using the unit-cell volume determined from our measurements and an isothermal compressibility κT=5.2×10−3 GPa−1 for URu2Si2, we determine the chemical pressure Pch in URu2−xFexSi2 as a function of x. The resulting temperature (T)–chemical pressure (Pch) phase diagram for URu2−xFexSi2 is in agreement with the established temperature (T)–external pressure (P) phase diagram of URu2Si2.

We describe a soft matter system of self-organized oblate micelles and plasmonic gold nanorods that exhibit a negative orientational order parameter. Because of anisotropic surface anchoring interactions, colloidal gold nanorods tend to align perpendicular to the director describing the average orientation of normals to the discoidal micelles. Helicoidal structures of highly concentrated nanorods with a negative order parameter are realized by adding a chiral additive and are further controlled by means of confinement and mechanical stress. Polarization-sensitive absorption, scattering, and two-photon luminescence are used to characterize orientations and spatial distributions of nanorods. Self-alignment and effective-medium optical properties of these hybrid inorganic-organic complex fluids match predictions of a simple model based on anisotropic surface anchoring interactions of nanorods with the structured host medium.

Canonical correlation feature selection for sensors with overlapping bands: Theory and application

作者： Paskaleva, Biliana Hayat, Majeed M. Wang, Zhipeng Tyo, J. Scott Krishna, Sanjay Department of Electrical and Computer Engineering Center for High Technology Materials University of New Mexico Albuquerque NM 87131 United States College of Optical Science University of Arizona Tucson AZ 85721 United States

The main focus of this paper is a rigorous development and validation of a novel canonical correlation feature-selection (CCFS) algorithm that is particularly well suited for spectral sensors with overlapping and noisy bands. The proposed approach combines a generalized canonical correlation analysis framework and a minimum mean-square-error criterion for the selection of feature subspaces. The latter induces ranking of the best linear combinations of the noisy overlapping bands and, in doing so, guarantees a minimal generalized distance between the centers of classes and their respective reconstructions in the space spanned by sensor bands. To demonstrate the efficacy and the scope of the proposed approach, two different applications are considered. The first one is separability and classification analysis of rock species using laboratory spectral data and a quantum-dot infrared photodetector (QDIP) sensor. The second application deals with supervised classification and spectral unmixing, and abundance estimation of hyperspectral imagery obtained from the Airborne Hyperspectral Imager sensor. Since QDIP bands exhibit significant spectral overlap, the first study validates the new algorithm in this important application context. The results demonstrate that proper postprocessing can facilitate the emergence of QDIP-based sensors as a promising technology for midwave- and longwave-infrared remote sensing and spectral imaging. In particular, the proposed CCFS algorithm makes it possible to exploit the unique advantage offered by QDIPs with a dot-in-a-well configuration, comprising their bias-dependent spectral response, which is attributable to the quantum Stark effect. The main objective of the second study is to assert that the scope of the new CCFS approach also extends to more traditional spectral sensors. © 2008 IEEE.

A prototype concurrent engineering tool has been developed for the preliminary design of composite topside structures for modern navy warships. This tool, named GELS for the Concurrent engineering of Layered Structures, provides designers with an immediate assessment of the impacts of their decisions on several disciplines which are important to the performance of a modern naval topside structure, including electromagnetic interference effects (EMI), radar cross section (RCS), structural integrity, cost, and weight. Preliminary analysis modules in each of these disciplines are integrated to operate from a common set of design variables and a common materials database. Performance in each discipline and an overall fitness function for the concept are then evaluated. A graphical user interface (GUI) is used to define requirements and to display the results from the technical analysis modules. Optimization techniques, including feasible sequential quadratic programming (FSQP) and exhaustive search are used to modify the design variables to satisfy all requirements simultaneously. The development of this tool, the technical modules, and their integration are discussed noting the decisions and compromises required to develop and integrate the modules into a prototype conceptual design tool.

NAVAL ENGINEERS JOURNAL 1997年第1期109卷 31-39页

作者： Joshi, CH Lindberg, JF Clark, AE Dr. Chad H. Joshi:is president of Energen Incorporated an engineering and development firm specializing in cryogenic and electromechanical systems. The research presented here was conducted while he was employed at American Superconductor Coporation where he held both technical and program management positions. While there Dr. Joshi managed the development of several demonstration products including the sonar transducer presented here. He holds M.S. and Sc.D. degreesfrom the Massachusetts Institute of Technology and a B.S. degree from the Worcester Polytechnic Institute. He has worked in several diverse fields including solar energy fluidized bed technology and superconductivity. His work on stochastic analysis of solar insolation was recognized by the ASME and his doctoral research was accorded international recognition for its unique contribution to understanding quenching in superconducting magnets. Dr. Joshi has numerous patents and more than thirty-five technical publications to his credit. He is a registered Professional Engineer in Massachusetts and an active member of ASME and IEEE. He is a co-founder and treasurer of the New England Chapter of the Cryogenics Society of America. He will be listed in Whos Who in the East in 1997. Jan Lindberg:is a physicist in the Transducers and Arrays Division of the Naval Undersea Warfare Center in New London Connecticut. He leads NUWC'S exploratory development efforts for transduction science and currently is spearheading an effort to introduce high-energy density active materials into tactical sonar systems. With the discovery of high temperature superconductivity he saw the potential benefit of integrating several emerging technologies and enticed American Superconductor Corp. to develop a high temperature superconducting transducer which resulted in the March 1993 demonstration of the world's first integrated high temperature superconducting device. Mr. Lindberg's current interests involve design of high power ultrasonic copolymer arrays characterization of

A low-frequency underwater acoustic transducer integrating high-temperature superconducting (HTS) coils and terbium-dysprosium (TbDy) magnetostrictive material was designed, fabricated and tested. This represents a novel application for high-temperature superconductivity and is a first example of an integrated system involving HTS coils cooled by a mechanical cryocooler. It also brings HTS technology together with a novel magnetic materials technology. The I-ITS coils were fabricated using react-and-wind BiSrCaCuO-2223 HTS wires. They produce a peak field of 0.1 Tesla at 50 K. A single-stage, Stirling-cycle cryocooler was used to cool the coils and the TbDy driver to cryogenic temperatures (50-65K). The coils provide an AC magnetic field superimposed on a DC bias field, which produces oscillatory strain within the magnetostrictive rod;this motion is transmitted through a cryostat to two head masses which project sound into the surrounding environment. high power acoustic output can be obtained by operating the transducer at its resonance frequencies of 520 Hz in air and 430 Hz underwater. This development demonstrates that, unlike low temperature superconductors, HTS wires can be considered for AC applications due to the low losses in these superconductors and the higher heat capacities of materials at temperatures above liquid helium.
