MoS<sub>2</sub>/Celgard Separator as Efficient Polysulfide Barrier for Long‐Life Lithium–Sulfur Batteries (2017)

A high lithium conductive MoS<sub>2</sub> /Celgard composite separator is reported as efficient polysulfides barrier in Li-S batteries. Significantly, thanks to the high density of lithium ions on MoS<sub>2</sub> surface, this composite separator shows high lithium conductivity, fast lithium diffusion, and facile lithium transference. When used in Li-S batteries, the separator is proven to be highly efficient for depressing polysulfides shuttle, leading to high and long cycle stability. With 65% of sulfur loading, the device with MoS<sub>2</sub> /Celgard separator delivers an initial capacity of 808 mAh g<sup>-1</sup> and a substantial capacity of 401 mAh g<sup>-1</sup> after 600 cycles, corresponding to only 0.083% of capacity decay per cycle that is comparable to the best reported result so far. In addition, the Coulombic efficiency remains more than 99.5% during all 600 cycles, disclosing an efficient ionic sieve preventing polysulfides migration to the anode while having negligible influence on Li<sup>+</sup> ions transfer across the separator. The strategy demonstrated in this work will open the door toward developing efficient separators with flexible 2D materials beyond graphene for energy-storage devices.
Enantioseparation of Isoxanthohumol in Beer by Hydroxypropyl-γ-cyclodextrin-Modified Micellar Electrokinetic Chromatography (2007)

Chiral resolution of isoxanthohumol (IX) in beer samples was performed by hydroxypropyl-gamma-cyclodextrin-modified micellar electrokinetic chromatography. The optimum running conditions were found to be 20 mM phosphate buffer (pH 7.0) containing 45 mM hydroxypropyl-gamma-cyclodextrin and 100 mM sodium dodecyl sulfate with an effective voltage of +20 kV at 20 degrees C using direct detection at 210, 295, and 370 nm. IX was detected in 12 beer samples and the total levels of (+)- and (-)-IX ranged from 0.15 to 1.4 mg/L. But the amount of xanthohumol (XN) was below the detection limit (0.017 mg/L). Each level of (-)-IX was almost the same as that of (+)-IX, suggesting that IX was a racemic mixture in these beer samples. The racemization of IX in beer could be attributed to the production of a racemic mixture from XN during boiling and to the fact that IX enantiomers were easily interconverted.

A Randomized, Double-Blind, Clinical Trial of Topical Clotrimazole Versus Miconazole for Treatment of Cutaneous Leishmaniasis in the Eastern Province of Saudi Arabia (1995)

The parenteral treatment currently available for cutaneous leishmaniasis (CL) is painful and potentially exposes patients to serious side effects. Thus, effective, topical therapy would be valuable. We assessed the efficacy of topical 1% clotrimazole and 2% miconazole creams in relation to early healing of lesions in CL in a randomized, double-blind clinical trial in 54 patients with 151 lesions treated for 30 consecutive days. Response to treatment was assessed at two weeks and 30 days and classified as fully healed, size reduced, no change, and size increased or worse. Of 89 lesions treated with clotrimazole, 14 (15.7%) healed fully, 42 (47.2%) were reduced in size, 20 (22.5%) showed no change, and 13 (14.6%) got worse. Correspondingly, in the 62 lesions treated with miconazole, none healed fully, 22 (35.5%) were reduced in size, 16 (25.8%) showed no change, and 24 (38.7%) got worse. The differences were statistically significant (P < 0.001). No side effects were observed. It is concluded that clotrimazole was the more effective of the two imidazoline compounds and is recommended as initial treatment for simple lesions.

CrowdsouRS: A crowdsourced reputation system for identifying deceptive online contents (2017)

In recent years, accelerated web-based technologies have revolutionized content generation and broadcast mecha-nisms through the Internet. Social media, blogs, e-newspaper, auction sites facilitate the creation and exchange of user-generated contents, which rarely go through any fact-finding mechanism or rigorous editorial process. This has fuelled the creation and publication of fake news in the web. The proliferation of social networks has been exploited to accelerate the distribution and propagation of such fake news at an unprecedented level, creating a major concern for the web. There have been several efforts undertaken to rectify this problem, unfortunately, none seems to be effective to root out this concerning issue. In this paper, we present CrowdsouRS, a Crowd-sourced Reputation System, implemented as a browser extension, for the web that leverages the wisdom of the crowd to identify and tag deceptive online contents. It aggregates reputation scores for a web page from multiple users, which is then visualized in order to help other users to determine if the contents of the web page are deceptive. We have evaluated the usability and effectiveness of CrowdsouRS with a number of users and our evaluations suggest that users find the tool useful in serving its purpose.
A reference method for measurement of alkaline phosphatase activity in human serum. (1983)

We present an official AACC reference method for the measurement of alkaline phosphatase, the culmination of optimization experiments conducted by a group of independent laboratories. The details of this method and evaluation of factors affecting the measurement are described. A metal ion buffer has been incorporated that maintains optimal and constant concentrations of zinc(II) and magnesium(II) ions. Final reaction conditions are: pH (30 degrees C), 10.40 +/- 0.05; 2-amino-2-methyl-1-propanol buffer, 0.35 mol/L; 4-nitrophenyl phosphate, 16.0 mmol/L; magnesium acetate, 2.0 mmol/L; zinc sulfate, 1.0 mmol/L; and N-(2-hydroxyethyl)ethylenediaminetriacetic acid, 2.0 mmol/L.
Multi-mode wide-band 130 nm CMOS WLAN and GSM/UMTS (2005)

This paper presents a fully integrated VCO covering the requirements of four cellular phone standards GSM, DCS, PCS and UMTS as well as WLAN 802.11 a/b/g. The frequency range from 3.42 GHz up to 11.45 GHz is managed with an innovative differential switchable inductor architecture. In addition a switched capacitor array and varactors are applied for precise tuning of all necessary frequency bands. The circuit is fabricated in a 130 nm CMOS process and housed into a VQFN 48 plastic package together with a proper direct conversion Rx-frontend solution for the cellular modes. The VCO has been measured and draws less than 13 mA at a supply voltage of 1.5 V whereas the VCO core needs only 2 mA. The evaluation of the VCO was done on a FR4 board.

Robust Multiple Manifolds Structure Learning (2012)

We present a robust multiple manifolds structure learning (RMMSL) scheme to robustly estimate data structures under the multiple low intrinsic dimensional manifolds assumption. In the local learning stage, RMMSL efficiently estimates local tangent space by weighted low-rank matrix factorization. In the global learning stage, we propose a robust manifold clustering method based on local structure learning results. The proposed clustering method is designed to get the flattest manifolds clusters by introducing a novel curved-level similarity function. Our approach is evaluated and compared to state-of-the-art methods on synthetic data, handwritten digit images, human motion capture data and motorbike videos. We demonstrate the effectiveness of the proposed approach, which yields higher clustering accuracy, and produces promising results for challenging tasks of human motion segmentation and motion flow learning from videos.
894. A Novel Mechanism between Type II Diabetes Mellitus and Procalcitonin Gene Expression (2005)

Objective: Procalcitonin (PCT) was originally described in 1984 as a 116-aminoacid protein with a molecular weight of 14,5 kDa. The PCT gene, referred to as Calc-1, is located on chromosome 11p15.4 and was sequenced in 1989. The promoter has sites for basal transcription factors but more interestingly, also has sites for NF|[kappa]||[beta]| (Nuclear factor |[kappa]||[beta]|) and AP-1(Activator protein-1), factors induced under inflammatory conditions. Type II diabetes mellitus is associated with oxidative stress and elevation of advanced glycation end products (AGEs). AGEs are produced by a non-enzymatic, Maillard reaction between reducing sugars and either proteins or lipids. AGE's interacts the receptor for advanced glycation end products (RAGE) and, RAGE activation is caused by elevation of transcriptional factors NF|[kappa]||[beta]| and AP-1. These factors induce procalcitonin gene expression. The aim of this study was to determine whether or not procalcitonin is a specific marker in patients with type II DM.
Code layout optimizations for transaction processing workloads (2001)

Commercial applications such as databases and Web servers constitute the most important market segment for high-performance servers. Among these applications, on-line transaction processing (OLTP) workloads provide a challenging set of requirements for system designs since they often exhibit inefficient executions dominated by a large memory stall component. This behavior arises from large instruction and data footprints and high communication miss rates. A number of recent studies have characterized the behavior of commercial workloads and proposed architectural features to improve their performance. However, there has been little research on the impact of software and compiler-level optimizations for improving the behavior of such workloads. This paper provides a detailed study of profile-driven compiler optimizations to improve the code layout in commercial workloads with large instruction footprints. Our compiler algorithms are implemented in the context of Spike, an executable optimizer for the Alpha architecture. Our experiments use the Oracle commercial database engine running an OLTP workload, with results generated using both full system simulations and actual runs on Alpha multiprocessors. Our results show that code layout optimizations can provide a major improvement in the instruction cache behavior, providing a 55% to 65% reduction in the application misses for 64-128K caches. Our analysis shows that this improvement primarily arises from longer sequences of consecutively executed instructions and more reuse of cache lines before they are replaced. We also show that the majority of application instruction misses are caused by self-interference. However, code layout optimizations significantly reduce the amount of self-interference, thus elevating the relative importance of interference with operating system code. Finally, we show that better code layout can also provide substantial improvements in the behavior of other memory system components such as the instruction TLB and the unified second-level cache. The overall performance impact of our code layout optimizations is an improvement of 1.33 times in the execution time of our workload.
Piezo-Resistive Semiconductor Microphones (1957)

A microphone using the piezo-resistive effect of n-type germanium has been designed and constructed with a cantilever beam arrangement. Frequency response curves were taken in a sound field of 10 microbars with the microphone in a bridge-type circuit and biased with 9 and 18 milliamperes. The microphone produces 10−11 watts in the flat low-frequency range and peaks to 10−9 watts at a resonance at 2570 cps with a total bias of 18 ma in a bridge-type circuit. Other designs of transducers and different types of semiconductor material are discussed. The performance of an ideal germanium rod microphone is compared with a standard carbon button transmitter. The construction and performance of an actual rod microphone is described. Sound pressures are applied by means of a diaphragm to a single crystal germanium rod with a cross-sectional area of 10−4 cm2.
Keep that lip stiff (2005)

An increase in splanchnic blood flow in both arterial and venous beds has been demonstrated in inflammatory bowel disease (IBD) by means of angiographic and scintigraphic studies. Doppler ultrasound (US) enables a non-invasive evaluation of splanchnic arterial inflow in the superior mesenteric artery (SMA) and of venous outflow in the portal vein. The aim of this study was to assess the role of Doppler US in detecting changes in the hemodynamic variables measured in patients with IBD. Forty-five patients with IBD were studied, including 22 with Crohn's disease (CD) and 23 with ulcerative colitis (UC), and compared with 45 matched normal subjects. The mean velocity of portal flow (Vmean) and the resistance index (RI) of the SMA were evaluated by Doppler US. In CD the Vmean of portal flow was significantly higher in patients with active disease than in controls (p less than 0.001) and patients with inactive disease (p less than 0.001). The RI of the SMA was significantly lower in active disease than in controls (p less than 0.005), but no significant difference was noted between active and inactive CD. Also in UC, the Vmean of portal flow was significantly higher in patients with active disease than in controls (p less than 0.01) and patients with inactive disease (p less than 0.05). The RI of the SMA was significantly lower in active disease than in controls (p less than 0.005) and in patients with inactive disease (p less than 0.005). Doppler follow-up studies were carried out in 10 patients after initiation of treatment.(ABSTRACT TRUNCATED AT 250 WORDS)
Oilseed Protein Properties Related to Functionality in Emulsions and Foams (1979)

Proteins have molecular properties that contribute to functionality of food ingredients (1,2,3). Genetic and agronomic factors, as well as processing conditions, alter protein properties of seeds and, in turn, change the functional behavior of their products (2,4-10). Specific proteins contribute to the select functional behavior of a food; i.e., fractionating and reconstituting techniques have established that the proteins glutenin and gliadin are responsible for most of the functional, or breadmaking, properties of wheat flour. Various oxidizing and reducing reagents are used to alter sulfhydryl and disulfide bonds in these wheat proteins, producing varying bread quality. Data presented in this paper illustrate the importance of understanding the physical and chemical properties of proteins in seeds and seed products, so that their ultimate contributions as ingredients in foods can be maximized. Efforts are under way to characterize the chemical properties of oilseed proteins and to relate these characteristics to the functional properties
Electrically-Transduced Chemical Sensors Based on Two-Dimensional Nanomaterials (2019)

Electrically-transduced sensors, with their simplicity and compatibility with standard electronic technologies, produce signals that can be efficiently acquired, processed, stored, and analyzed. Two dimensional (2D) nanomaterials, including graphene, phosphorene (BP), transition metal dichalcogenides (TMDCs), and others, have proven to be attractive for the fabrication of high-performance electrically-transduced chemical sensors due to their remarkable electronic and physical properties originating from their 2D structure. This review highlights the advances in electrically-transduced chemical sensing that rely on 2D materials. The structural components of such sensors are described, and the underlying operating principles for different types of architectures are discussed. The structural features, electronic properties, and surface chemistry of 2D nanostructures that dictate their sensing performance are reviewed. Key advances in the application of 2D materials, from both a historical and analytical perspective, are summarized for four different groups of analytes: gases, volatile compounds, ions, and biomolecules. The sensing performance is discussed in the context of the molecular design, structure-property relationships, and device fabrication technology. The outlook of challenges and opportunities for 2D nanomaterials for the future development of electrically-transduced sensors is also presented.
Differential uptake of cis-diamminedichloroplatinum (II) by sensitive and resistant murine L1210 leukemia cells. (1987)

The uptake of cis-[14C]dichloro(ethylenediamine)platinum(II) (cis-DEP) is reduced in cis-diamminedichloroplatinum(II) (cis-DDP)-resistant L1210 cells [L1210/DDP (SRI)] in comparison to cis-DDP-sensitive L1210 cells (L1210/0). A difference in uptake is observed as early as 6 min after addition of cis-[14C]DEP and increases to approximately 3-fold after 30 min. This reduction in uptake is reflected in a decrease in the binding of platinum to DNA isolated from cis-DDP-treated cells as measured by atomic absorption spectroscopy and in the quantity of intracellular cis-DEP metabolites as measured by high-performance liquid chromatography. Similar differences in uptake are observed between ascitic L1210/0 and L1210/DDP (SRI) cells in vitro and in vivo, showing that the differences in uptake are not due to an artifact of the culturing process. The differences in cis-DEP uptake between the two cell lines were relatively unchanged during 7 mo in culture; however, both cell lines exhibited altered sensitivities to cis-DEP during extended culturing. No difference was observed in the efflux of cis-DEP by the two cell lines. Similarly, no difference in nonprotein and total sulfhydryl contents was observed between L1210/0 and L1210/DDP (SRI) cells. The difference in uptake (3-fold) of cis-DEP between L1210/0 and L1210/DDP (SRI) cells may not account fully for the observed differences in sensitivity of the two cell lines to cis-DDP (18-fold) and cis-DEP (19-fold). A portion of the resistance may be due to differences in the capacity of the two cell lines to survive in the presence of platinum damage.
Magnetic field measurements with a novel surface micromachined magnetic-field sensor (2000)

The surface micromachining process of Robert Bosch GmbH has been used to fabricate a novel type of magnetic-field sensor. The Lorentz force, caused by the interaction of a current and an external magnetic field in a suspended surface micromachined conducting beam, laterally displaces the suspended structure. The displacement of the structure is converted into a capacitance change by comb-electrodes, which form a differential capacitor. An appropriate electronic circuitry measures the magnetic field by quantifying the displacement of the conducting beam. In order to increase sensitivity to magnetic fields, the magnitude of the deflection is increased by resonant operation in a vacuum ambient. The sensor obtains its vacuum environment by encapsulation with a new wafer bonding process. Prototype sensors with resonant frequencies in the range around 1300 Hz show Q-factors above 30. With these samples, relative magnetic sensitivities of 900 000 (V/A/spl middot/T) with a detection limit in the sub /spl mu/T-range are reported.
Vasoactive Intestinal Peptide and Pituitary Adenylate Cyclase-Activating Polypeptide Inhibit Expression of Fas Ligand in Activated T Lymphocytes by Regulating c-Myc, NF-κB, NF-AT, and Early Growth Factors 2/3 (2001)

Activation-induced cell death in T cells, a major mechanism for limiting an ongoing immune response, is initiated by Ag reengagement and mediated through Fas/Fas ligand interactions. Vasoactive intestinal peptide (VIP) and pituitary adenylate cyclase-activating polypeptide (PACAP), two multifunctional neuropeptides, modulate innate and adaptive immunity. We reported previously that VIP/PACAP protect T cells from activation-induced cell death through down-regulation of Fas ligand (FasL). In this study, we investigate the molecular mechanisms involved in the protective effect of VIP and PACAP. VIP/PACAP reduce in a dose-dependent manner anti-CD3-induced apoptosis in 2B4.11 T cell hybridomas. The protective effect is mediated through the specific type 2 VIP receptor, and the cAMP/protein kinase A pathway. A functional study demonstrates that VIP/PACAP inhibit activation-induced FasL expression. VIP/PACAP inhibit the expression and/or DNA-binding activity of several transcriptional factors involved in FasL expression, i.e., c-myc, NF-kappaB, NF-ATp, and early growth factors (Egr) 2/3. The inhibition of NF-kappaB binding is due to the stabilization of I-kappaB (inhibitory protein that dissociates from NF-kappaB), through the inhibition of I-kappaB kinase alpha activity. Subsequently, p65 nuclear translocation is significantly reduced. The inhibition in NF-ATp binding results from a calcineurin-independent reduction in NF-ATp nuclear translocation. VIP/PACAP inhibit the expression of Egr2 and 3, but not of Egr1. The effects on the transcriptional factors are mediated through type 2 VIP receptor with cAMP as secondary messenger.
