Provably Secure Trusted Access Protocol for WLAN Mesh Networks (2008)

Available WLAN Mesh network access protocols and trusted network connect protocols can not satisfy the performance and security requirements of WLAN Mesh networks in trusted environment. A provably secure trusted access protocol MN-TAP for the WLAN Mesh Networks is proposed. Such protocol will achieve authentication and key confirmation among the access requestor, policy enforcement point and policy decision point within 4 protocol rounds. Meanwhile, the protocol can realize the platform authentication and platform integrity verification in the first round of protocol interaction, which will improve the efficiency of the protocol and decrease the overhead of the server. We use a provably secure model, named the universally composable secure model, to analyze the security of the protocol. And we use of compare analysis to discover the performance advantages of the protocol. The results show that: the protocol is a UC-secure protocol, and the performance has great advantages over the current protocols.
Highly Diastereoselective Nitrone Cycloaddition onto a Chiral Ketene Equivalent:  Asymmetric Synthesis of Cispentacin (2002)

[reaction: see text] A highly diastereoselective intramolecular nitrone cycloaddition onto a chiral ketene equivalent, obtained by Horner-Wadsworth-Emmons olefination of either enantiomer of bis-sulfinyl phosphonate 6, is described. Cycloaddition gave 5,5-disubstituted isoxazolidine 10 in good yield as a single diastereomer. Catalytic hydrogenolysis of 10 furnished either enantiomer of optically pure cis-2-aminocyclopentane-1-carboxylic acid.
Selective epitaxial growth of stepwise SiGe:B at the recessed sources and drains: A growth kinetics and strain distribution study (2016)

The selective epitaxial growth of Si1-xGex and the related strain properties were studied. Epitaxial Si1-xGex films were deposited on (100) and (110) orientation wafers and on patterned Si wafers with recessed source and drain structures via ultrahigh vacuum chemical vapor deposition using different growing steps and Ge concentrations. The stepwise process was split into more than 6 growing steps that ranged in thicknesses from a few to 120 nm in order to cover the wide stages of epitaxial growth. The growth rates of SiGe on the plane and patterned wafers were examined and a dependence on the surface orientation was identified. As the germanium concentration increased, defects were generated with thinner Si1-xGex growth. The defect generation was the result of the strain evolution which was examined for channel regions with a Si1-xGex source/drain (S/D) structure.
Synthesis of fluorene‐based high performance polymers. I. Poly(arylene thioether)s with excellent solubility and high refractive index (2007)

Abstract Several poly(arylene thioether)s ( PTEs ) containing a fluorene moiety were synthesized by the polycondensation of masked dithiols such as 9,9‐bis(4‐( N,N ‐dimethyl‐ S ‐carbamoyl)phenyl)fluorene and various difluoroarenes. All PTEs were obtained in quantitative yields. The PTEs showed good thermal stability: the 10% weight loss temperature was over 480 °C under both nitrogen and air atmosphere by TGA, and glass temperature was within a range of 204–275 °C by DSC. Most PTEs exhibited remarkably high refractive index values in a range of 1.66–1.72 at 589 nm, whereas they had a very low degree of birefringence properties. Furthermore, the PTEs showed high solubility in ordinary organic solvents such as chloroform, N ‐methylpyrrolidone, and tetrahydrofuran. © 2007 Wiley Periodicals, Inc.

Extractive Summarization Using Multi-Task Learning with Document Classification (2017)

The need for automatic document summarization that can be used for practical applications is increasing rapidly. In this paper, we propose a general framework for summarization that extracts sentences from a document using externally related information. Our work is aimed at single document summarization using small amounts of reference summaries. In particular, we address document summarization in the framework of multitask learning using curriculum learning for sentence extraction and document classification. The proposed framework enables us to obtain better feature representations to extract sentences from documents. We evaluate our proposed summarization method on two datasets: financial report and news corpus. Experimental results demonstrate that our summarizers achieve performance that is comparable to stateof-the-art systems.
Bulk electroconvection in electrolyte (2005)

Bulk electroconvection pertains to flow induced by the action of the mean electric field upon the residual space charge in the macroscopic regions of a locally quasielectroneutral strong electrolyte. There existed a long time controversy in the literature as to whether quiescent electric conduction from such an electrolyte into a uniform charge selective solid, such as a metal electrode or an ion exchange membrane, is stable with respect to bulk electroconvection and whether bulk electroconvection at a nonuniform solid of this type may develop into a fully fledged flow. Numerical results reported in this paper confirm previous conclusions of a linear stability analysis concerning the nonexistence of bulk electroconvective instability, while we suggest that bulk electroconvection at a nonuniform charge selective solid results in a fully fledge flow on the length scale of nonuniformity of the surface.
Effect of ethylene vinyl acetate (EVA) closed cell foam on transmitted forces in mouthguard material (2002)

The inclusion of gas in the form of a closed cell foam in 4 mm thick EVA mouthguard materials did not improve the impact performance of the EVA mouthguard material.

Acanthamoeba keratitis in New Zealand, including two cases with <i>in vivo</i> resistance to polyhexamethylene biguanide (1998)

For treatment PHMB, hexamidine rather than propamidine and surgical debridement are favoured. While all Acanthamoeba isolates show good in vitro sensitivity to PHMB, the in vivo response is not always proportionate. A bacterial endosymbiont may have been a factor in the favourable outcome of one protracted case.
Polymers for high performance interconnects (1997)

It is well-known that capacitance in the metallization is becoming too great to allow the continued use of SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> as the intermetal dielectric below about the 0.25 μm technology node. One of many possible replacements for SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> are organic polymers. Organic polymers are not drop-in replacements, however, and their successful integration into functional circuits requires new fabrication procedures and integration schemes. The embedded dielectric scheme offers a sound evolutionally path for their successful integration into a subtractive etch, aluminum-based integrated circuit. The embedded dielectric scheme effectively lowers total capacitance and the line-line/total capacitance ratio while minimally changing the rest of the metallization fabrication processes including via formation. Vapor deposited polymers which are conformably deposited like Parylene-n are more easily integrated into the embedded dielectric scheme than nonconformal spin-on dielectric films. Parylene-n copolymers with dielectric permittivities as low as 2.3 also are excellent candidate materials for use in the embedded dielectric scheme and they also have equivalent thermal stability as the homopolymer. New copolymers with comonomers of different functionality should improve both the adhesion and thermal stability of the intermetal dielectric.
Optimal Surface-Electrode Trap Lattices for Quantum Simulation with Trapped Ions (2009)

Trapped ions offer long internal state (spin) coherence times and strong interparticle interactions mediated by the Coulomb force. This makes them interesting candidates for quantum simulation of coupled lattices. To this end, it is desirable to be able to trap ions in arbitrary conformations with precisely controlled local potentials. We provide a general method for optimizing periodic planar radio-frequency electrodes for generating ion trapping potentials with specified trap locations and curvatures above the electrode plane. A linear-programming algorithm guarantees globally optimal electrode shapes that require only a single radio-frequency voltage source for operation. The optimization method produces final electrode shapes that are smooth and exhibit low fragmentation. Such characteristics are desirable for practical fabrication of surface-electrode trap lattices.
Effect of oxygen incorporation on magnetoresistance in Co/Cu multilayers (1994)

The background pressure dependence of magnetoresistance (MR) ratio of Co/Cu multilayer films and the effect of the Fe buffer layer were studied. Secondary ion mass spectrometry (SIMS) measurement of the films and in situ quadrupole mass spectrometry (QMS) analysis in conjunction with background pressure dependence of MR ratio confirmed that the oxidation of Co/Cu gives a crucial influence to the giant magnetoresistance (GMR) effect. The oxidation of Co/Cu weakens the antiferromagnetic coupling, and results in the low MR ratio. The Fe buffer layer absorbs the residual oxygen, and this leads to the increase of the MR ratio. The MR ratio of (Co1 nm/Cu1 nm)100/Fe2.5 nm film deposited under low background pressure and high deposition rate so as to suppress oxidation reached over 80% at RT and 160% at 2 K.
Genetic dissection of Drosophila adenylate cyclase. (1985)

The Drosophila learning mutant rutabaga is missing calcium/calmodulin activation of adenylate cyclase (EC4.6.1.1). The mutation was mapped at a finer resolution to X chromosome bands 12F5-7. By comparing wild-type and mutant cyclase activities, the relative responsiveness of the calcium-sensitive and calcium-insensitive components to different ligands could be determined; the calcium-sensitive fraction of the total cyclase activity was significantly less responsive to guanyl nucleotides and monoamines. The results suggest that the component of cyclase activity that is stimulated by calcium/calmodulin, possibly a genetically distinct catalytic subunit, is not coupled to the G subunit or the G subunit/monoamine receptor complex.
Integrated CMOS dew point sensors for relative humidity measurement (2004)

This work deals with the development of integrated relative humidity dew point sensors realized by adopting standard CMOS technology for applications in various fields. The proposed system is composed by a suspended plate that is cooled by exploiting integrated Peltier cells. The cold junctions of the cells have been spread over the plate surface to improve the homogeneity of the temperature distribution over its surface, where cooling will cause the water condensation. The temperature at which water drops occur, named dew point temperature, is a function of the air humidity. Measurement of such dew point temperature and the ambient temperature allows to know the relative humidity. The detection of water drops is achieved by adopting a capacitive sensing strategy realized by interdigited fixed combs, composed by the upper layer of the adopted process. Such a capacitive sensor, together with its conditioning circuit, drives a trigger that stops the cooling of the plate and enables the reading of the dew point temperature. Temperature measurements are achieved by means of suitably integrated thermocouples. The analytical model of the proposed system has been developed and has been used to design a prototype device and to estimate its performances. In such a prototype, the thermoelectric cooler is composed by 56 Peltier cells, made by metal 1/poly 1 junctions. The plate has a square shape with 200 μm side, and it is realized by exploiting the oxide layers. Starting from the ambient temperature a temperature variation of ΔT = 15 K can be reached in 10 ms thus allowing to measure a relative humidity greater than 40%.
Relaying MIMO channel capacity with imperfect channel knowledge at the receiver (2007)

In this paper, we study a scenario of multiple input multiple output system using relays in an angle showing how the topology of the system can play its role in the situation. We assume perfect channel knowledge at the transmitter and the relay(s) which is represented by a matrix of zero mean circularly symmetric complex Gaussian (ZMCSCG) random variables with known covariances, but imperfect channel state information (CSI) at the receiver. The imperfect CSI at the receiver causes errors to the received signal and as a consequence the channel capacity saturates. We derive the channel capacity formulas for two different transmission algorithms; uniform and waterfilling. Finally we simulate and compare the results
Managing multi‐party documents in a network computing environment (1998)

A Multi-Party Document (MPD) is one that contains multiple parts intended for multiple recipients, in that each recipient does not necessarily need to know the existence, and therefore the corresponding content, of the other parts of the document intended for other recipients. MPDs pose new requirements, namely, transparency and security, on the underlying system. Equipping the system with MPD supports will relieve user burdens and enhance the security measures of the system in protecting the integrity and privacy of document contents. This paper reviews some traditional and current document management approaches and their shortcomings with respect to the stated requirements, and proposes extensions to HTML, the most popular open document standard, with MPD supports for practical reasons. The main implementation issues, including dynamic document construction and secured document transmission and repository, are also discussed. MPD finds many applications in our daily life, especially in the ever growing Internet and Intranet environments. The extension needed to the underling system is straightforward, while the pay-off can be substantial. © 1998 John Wiley & Sons, Ltd.
Prescaled 6.3 GHz clock recovery from50 Gbit/s TDM optical signal with 50 GHz PLLusing four-wave mixing in atravelling-wave laser diode optical amplifier (1994)

Successful 50 GHz operation of a phaselocked loop is demonstrated using four-wave mixing in a travelling-wave laser diode optical amplifier. A prescaled 6.3 GHz clock is recovered from a 50 Gbit/s TDM optical signal using the 50 GHz phase comparison output obtained as the crosscorrelation between a 50 Gbit/s optical signal and a short (< 10 ps) 6.3 GHz optical clock pulse train in the generated four-wave-mixing light.
A fully digital, energy-efficient, adaptive power-supply regulator (1999)

A voltage scaling technique for energy-efficient operation requires an adaptive power-supply regulator to significantly reduce dynamic power consumption in synchronous digital circuits. A digitally controlled power converter that dynamically tracks circuit performance with a ring oscillator and regulates the supply voltage to the minimum required to operate at a desired frequency is presented. This paper investigates the issues involved in designing a fully digital power converter and describes a design fabricated in a MOSIS 0.8-/spl mu/m process. A variable-frequency digital controller design takes advantage of the power savings available through adaptive supply-voltage scaling and demonstrates converter efficiency greater than 90% over a dynamic range of regulated voltage levels.
Still More Squeezing of Optical Noise (1987)

Quantum optics experimenters have been pushing hard to generate greater “squeezing.” This drive was encouraged by last year's milestone demonstration at AT&T Bell Labs that the noise from an optical cavity had been measurably squeezed, that is, that the noise in one phase of the signal had been reduced below the level normally associated with quantum mechanical fluctuations in the vacuum field. Until then, that vacuum noise level had represented the fundamental quantum limit to precision in optical experiments. The Bell Labs experiment reduced the noise by 7–10% below this normal quantum limit (see PHYSICS TODAY, March 1986, page 17), and several experiments since then have achieved noise reductions of at least 20%. The most spectacular results to date have been obtained by a team at the University of Texas at Austin consisting of Ling-An Wu, Min Xiao, H. Jeffrey Kimble, John L. Hall (of the Joint Institute for Laboratory Astrophysics) and Huifa Wu, who have observed noise reductions to more than 60% below the normal level.
Effect of aspartate and glutamate on experimental myocardial infarction in rats. (1989)

Cardiac necrosis was produced in rats by administering isoproterenol sulphate (85 mg/kg, sc for 4 days). The myocardial damage was proved by observing the elevated levels of serum aspartate amino-transferase, lactate dehydrogenase and creatine phosphokinase and the changes were confirmed by histopathology of the tissue. Both aspartate and glutamate (100 mg/kg, ip) significantly reduced the elevated levels of these enzymes. The average degree of cardiac necrosis produced in these rats when observed macroscopically and histologically was also found to be significantly reduced on pretreatment with aspartate and glutamate.
High‐Efficiency Anion Exchange Membrane Water Electrolysis Employing Non‐Noble Metal Catalysts (2020)

Abstract Alkaline anion exchange membrane (AEM) water electrolysis is a promising technology for producing hydrogen using renewable energies. However, current AEM electrolyzers still employ noble‐metal‐containing electrocatalysts, or have significant overpotential loss, or both. Here non‐noble‐metal electrocatalysts for both the hydrogen and oxygen evolution reactions (HER and OER) are developed. Both catalysts are made of a same NiMo oxide. Judicious processing of these materials in a mixed NH 3 /H 2 atmosphere results in a NiMo‐NH 3 /H 2 catalyst, which has superior activity in HER, delivering 500 mA cm −2 at an overpotential of 107 mV. Doping Fe ions into the NiMo‐NH 3 /H 2 catalyst yields an Fe‐NiMo‐NH 3 /H 2 catalyst, which is highly active for the OER, delivering 500 mA cm −2 at an overpotential of 244 mV. These catalysts are integrated into an AEM electrolyzer, which delivers 1.0 A cm −2 at 1.57 V at 80 °C in 1 m KOH. The energy conversion efficiency at this current density is as high as 75%. This work demonstrates high‐efficiency AEM electrolysis using earth‐abundant catalytic materials.
Identification of a novel “almost neutral” μ‐opioid receptor antagonist in CHO cells expressing the cloned human μ‐opioid receptor (2009)

The basal (constitutive) activity of G protein-coupled receptors allows for the measurement of inverse agonist activity. Some competitive antagonists turn into inverse agonists under conditions where receptors are constitutively active. In contrast, neutral antagonists have no inverse agonist activity, and they block both agonist and inverse agonist activity. The mu-opioid receptor (MOR) demonstrates detectable constitutive activity only after a state of dependence is produced by chronic treatment with a MOR agonist. We therefore sought to identify novel MOR inverse agonists and novel neutral MOR antagonists in both untreated and agonist-treated MOR cells. CHO cells expressing the cloned human mu receptor (hMOR-CHO cells) were incubated for 20 h with medium (control) or 10 microM (2S,4aR,6aR,7R,9S,10aS,10bR)-9-(benzoyloxy)-2-(3-furanyl)dodecahydro-6a,10b-dimethyl-4,10-dioxo-2H-naphtho-[2,1-c]pyran-7-carboxylic acid methyl ester (herkinorin, HERK). HERK treatment generates a high degree of basal signaling and enhances the ability to detect inverse agonists. [(35)S]-GTP-gamma-S assays were conducted using established methods. We screened 21 MOR "antagonists" using membranes prepared from HERK-treated hMOR-CHO cells. All antagonists, including CTAP and 6beta-naltrexol, were inverse agonists. However, LTC-274 ((-)-3-cyclopropylmethyl-2,3,4,4alpha,5,6,7,7alpha-octahydro-1H-benzofuro[3,2-e]isoquinolin-9-ol)) showed the lowest efficacy as an inverse agonist, and, at concentrations less than 5 nM, had minimal effects on basal [(35)S]-GTP-gamma-S binding. Other efforts in this study identified KC-2-009 ((+)-3-((1R,5S)-2-((Z)-3-phenylallyl)-2-azabicyclo[3.3.1]nonan-5-yl)phenol hydrochloride) as an inverse agonist at untreated MOR cells. In HERK-treated cells, KC-2-009 had the highest efficacy as an inverse agonist. In summary, we identified a novel and selective MOR inverse agonist (KC-2-009) and a novel MOR antagonist (LTC-274) that shows the least inverse agonist activity among 21 MOR antagonists. LTC-274 is a promising lead compound for developing a true MOR neutral antagonist.
Long-term Efficacy of Biomodeled Polymethyl Methacrylate Implants for Orbitofacial Defects (2006)

Computed tomographic biomodeled, prefabricated, heat-cured polymethyl methacrylate implants are well tolerated in the long term. Their advantages include customized design, long-term biocompatibility, and excellent aesthetic results.
Signal-Processing Machines at the Postsynaptic Density (2000)

Dendrites of individual neurons in the vertebrate central nervous system are contacted by thousands of synaptic terminals relaying information about the environment. The postsynaptic membrane at each synaptic terminal is the first place where information is processed as it converges on the dendrite. At the postsynaptic membrane of excitatory synapses, neurotransmitter receptors are attached to large protein "signaling machines" that delicately regulate the strength of synaptic transmission. These machines are visible in the electron microscope and are called the postsynaptic density. By changing synaptic strength in response to neural activity, the postsynaptic density contributes to information processing and the formation of memories.
