X-ray Absorption Near Edge Structure Study on Valence Changes of Ni and Co in Li1-xNi0.82Co0.15M0.03O2 (M = Nb, Ti) Cathode Materials (2010)

X-ray absorption near edge (XANES) measurements at K-edges of Ni and Co were carried out on the Li deintercalated Li1−xNi0.82Co0.15M0.03O2 (M=Nb, Ti) cathode materials for Li secondary batteries. Samples were prepared by two different ways of Li deintercalation. One was cathode materials removed from the coin cell charged in the different degree of Li deintercalation and the other was chemically processed with hydrochloric acid in the aqueous solution. Comparisons of XANES spectra between LNCO and Ti or Nb doped LNCO were made, and it was found that the formation of Ni4+ was greatly reduced in the charged cathode materials with the dope of Ti or Nb. The similar results were obtained within samples prepared by the real charge and the chemical charge. Valence of Co was invariable during the charge, and was supposed to be trivalent.
Translocation and activation of AKT2 in response to stimulation by insulin. (1998)

The AKT2 oncogene encodes a protein-serine/threonine kinase that was recently shown to be activated by a variety of growth factors. In addition, we previously showed that AKT2 is abundant in brown fat and skeletal muscle, tissues that are highly insulin responsive and that play a role in glucose metabolism. In this study, we demonstrate that AKT2 is activated in response to stimulation by insulin in a dose- and time-dependent manner in human ovarian carcinoma cells and that activation of AKT2 is abolished in cells pretreated with wortmannin, an inhibitor of phosphatidylinositol 3-kinase (PI 3-kinase). Activation of AKT2 is manifested by changes in its phosphorylation state. Immunofluorescence experiments demonstrate that AKT2 is translocated to the plasma membrane after insulin stimulation, and this translocation is abolished by wortmannin. Both wild-type AKT2 activated by insulin and constitutively active AKT2, which has been targeted to the membrane by the addition of a myristoylation signal, were found to inactivate glycogen synthase kinase-3 (GSK-3) in vitro. GSK-3 was not inactivated by a catalytically inactive AKT2 mutant. Collectively, these data indicate that activation of AKT2 by insulin is mediated by PI 3-kinase and that GSK-3 is a downstream target of AKT2, suggesting a potentially important role of AKT2 in glycogen synthesis and other GSK-3 signaling pathways.
Knock‐down of LAR protein tyrosine phosphatase induces insulin resistance (2005)

To test the role of the leukocyte common antigen-related protein tyrosine phosphatase (LAR) as a regulator of insulin receptor (IR) signalling, an siRNA probe against LAR was developed. Knock-down of LAR induced post-receptor insulin resistance with the insulin-induced activation of PKB/Akt and MAP kinases markedly inhibited. The phosphorylation and dephosphorylation of the IR and insulin receptor substrate (IRS) proteins were unaffected by LAR knock-down. These results identify LAR as a crucial regulator of the sensitivity of two key insulin signalling pathways to insulin. Moreover, the siRNA probe provides a molecular tool of general applicability for further dissecting the precise targets and roles of LAR.
Control over WirelessHART network (2010)

It has been observed that the history of industrial process control development is also a history of reducing the number of wires necessary for effecting the control. Control over wireless is the end of this evolution. Wireless control faces a lot of challenges such as security, reliability, feedback latency, battery longevity, etc. In this paper we report some experience with implementing control over wireless. The platform we use is the WirelessHART mesh network, the first international industrial wireless control standard. We describe a full implementation of the standard and study the issues and solutions in its application. Our data suggest that WirelessHART technology is up to the challenge of wireless control.
Chemical Modification of Poly(2,6-dimethyl-1,4-phenylene oxide) and Properties of the Resulting Polymers (1988)

The chemical modification of poly (2,6-dimethyl-1,4-phenylene oxide) (PPO) by several polymer analogous reactions is presented. The chemical modification was accomplished by the electrophilic substitution reactions such as: bromination, sulfonylation and acylation. The permeability to gases of the PPO and of the resulting modified polymers is discussed. Very good permeation properties to gases, better than for PPO were obtained for the modified structures. The thermal behavior of the substituted polymers resembled more or less the properties of the parent polymer while their solution behavior exhibited considerable differences.
Highly Efficient Process for Production of Biofuel from Ethanol Catalyzed by Ruthenium Pincer Complexes (2016)

A highly efficient ruthenium pincer-catalyzed Guerbet-type process for the production of biofuel from ethanol has been developed. It produces the highest conversion of ethanol (73.4%, 0.02 mol% catalyst) for a Guerbet-type reaction, including significant amounts of C4 (35.8% yield), C6 (28.2% yield), and C8 (9.4% yield) alcohols. Catalyst loadings as low as 0.001 mol% can be used, leading to a record turnover number of 18 209. Mechanistic studies reveal the likely active ruthenium species and the main deactivation process.
A Comparative Study of Deep-UV Thin Resist by Electron Beam Stabilization. (2000)

The method of electron beam stabilization has been applied for improving the etch selectivity of resist patterns having an aspect ratio of less than 3:1. With the application of electron beam stabilization, the Deep-UV photoresists based on the chemical structures of Acetal and ESCAP have been evaluated with respect to etch selectivity as a function of electron beam dose and etch condition. A resist etch rate reduction of 20 percent and 26 percent in a metal etch process, have been observed for the two types of resists, Acetal and ESCAP respectively, at 2000C1cm2. The thermal and chemical properties were characterized before and after electron beam stabilization using DSC, TGA, and FT-IR. The cross-sectional views of resist patterns after electron beam processing were also investigated to understand the chemical stability of resist during the electron beam process.
All-optical silicon simplified passive modulation (2012)

In this paper we present an all-optical silicon based modulator suggested also for high power operation and for pulse picker application being used as part of fiber lasers system. The paper theoretically and experimentally investigates several new and important insights involving the dependence of the relative transmission on the pump pulse energy for different finesse values of the constructed cavity as well as the dependence of the response rate of the device to the pump wavelength due to coexistence of two physical recombination processes: fast surface effect and slow bulk recombination. To adapt the constructed silicon based cavity to be used in lasers applications, we aligned the pump and the signal beams to co-propagate through the device while the usage of a cavity allowed a low power pump to yield a significant extinction ratio at the output of the device.

Findings The only protection libraries possess is planning. Originality/value Stresses the need to have a disaster recovery plan in place.
PAX8 Reliably Distinguishes Ovarian Serous Tumors From Malignant Mesothelioma (2010)

Ovarian serous neoplasms can have morphologic overlap with malignant mesothelioma. The distinction is clinically important, yet most studies have failed to identify immunostains that reliably distinguish these 2 tumor types. Recently, transcription factor PAX8 was shown to be a sensitive and relatively specific marker for Müllerian tumors. In addition, some studies suggest that h-caldesmon is sensitive and specific for mesothelioma when compared with serous ovarian tumors. The goal of this study was to evaluate whether PAX8 and h-caldesmon expression can successfully distinguish mesothelioma from serous ovarian tumors. Immunohistochemistry was carried out using PAX8 and h-caldesmon antibodies on archival tissue from 254 ovarian serous tumors and 50 mesothelial tumors. Nuclear and cytoplasmic immunoreactivity were considered positive for PAX8 and h-caldesmon, respectively. PAX8 staining was present in 99% of high-grade serous ovarian carcinomas and all (100%) low-grade ovarian carcinomas and serous borderline tumors; however, only 74% of these cases (188/254) were diffusely positive in more than 50% of tumors cells, and intensity ranged from strong to weak. None of the pleural malignant mesotheliomas were reactive with PAX8. However, 2/23 (9%) peritoneal malignant mesotheliomas showed focal and/or weak staining for PAX8; the remaining cases were negative. Two well-differentiated papillary mesotheliomas and 1 multicystic mesothelioma each showed some staining for PAX8. h-caldesmon was negative in all serous neoplasms and all mesothelial neoplasms, except 1 pleural malignant mesothelioma which showed patchy immunoreactivity. Strong PAX8 staining is highly specific (P<0.00001) for ovarian serous tumors when compared with malignant mesotheliomas of the peritoneum and pleura. The presence of weak staining for PAX8 in the 3 "noninvasive" mesotheliomas questions the use for PAX8 in this differential diagnosis. On the basis of this study, h-caldesmon is not a useful marker for mesothelioma.
Enzyme Activity in Crevicular Fluid for Detection and Prediction of Clinical Attachment Loss in Patients with Chronic Adult Periodontitis (1988)

Previous reports have described a method by which multiple constituents can be analyzed from a sample of gingival crevicular fluid (GCF) collected with a precut filter paper strip. In this study the relationship of changes in GCF levels of the vertebrate (lysosomal) enzymes beta-glucuronidase (BG) and arylsulfatase (AS) and the cytoplasmic enzyme lactate dehydrogenase (LDH) was evaluated longitudinally in reference to loss of clinical attachment in patients with existing chronic adult periodontitis. Thirty-six patients were followed for six months. Clinical attachment loss was recorded as the change between the baseline and three month examinations, and the three- and six-month examinations. GCF analysis was performed at baseline and three months. Three groups of patients were identified based on disease progression. Group I patients (N = 5) displayed a generalized form of disease activity. In these patients we observed clinical attachment loss of at least 2.0 mm at a minimum of three unrelated sites. Group II patients (N = 4) displayed a localized form of disease activity. In these patients clinical attachment loss of at least 2.5 mm occurred at one site, or two anatomically related sites. Group III patients (N = 27) did not display clinical attachment loss as defined here. Enzyme analysis was evaluated as a whole mouth score (the per cent of samples from a patient in which enzyme activity was at least twice the population mean) and at individual samples. Group I patients could be identified by elevated whole mouth scores for BG, while Group II patients could not be identified by whole mouth scores for any of the enzymes.(ABSTRACT TRUNCATED AT 250 WORDS)
Covalent Inhibition in Drug Discovery (2019)

Although covalent inhibitors have been used as therapeutics for more than a century, there has been general resistance in the pharmaceutical industry against their further development due to safety concerns. This inclination has recently been reverted after the development of a wide variety of covalent inhibitors to address human health conditions along with the US Food and Drug Administration (FDA) approval of several covalent therapeutics for use in humans. Along with this exciting resurrection of an old drug discovery concept, this review surveys enzymes that can be targeted by covalent inhibitors for the treatment of human diseases. We focus on protein kinases, RAS proteins, and a few other enzymes that have been studied extensively as targets for covalent inhibition, with the aim to address challenges in designing effective covalent drugs and to provide suggestions in the area that have yet to be explored.
On-Line Assertion-Based Verification with Proven Correct Monitors (2006)

In the context of embedded systems design, the authors developed an original method for generating hardware that monitors signals whose behavior is specified by logical and temporal properties written in PSL. The method is based on a library of primitive digital components, and a technique to interconnect them, both formally proven correct with respect to the mathematical semantics of PSL. The resulting digital module can be properly connected to the signals of the design under scrutiny. Monitoring runs concurrently with the observed signals, and notifies its environment whether the property checking is terminated or is still pending. A prototype implementation on a FPGA platform provides enough execution efficiency to allow the verification of a system on a chip running its own software. In this method, on-line monitoring imposes a circuit overhead that increases gracefully with the number of nested PSL operators, and the upper bound of the temporal observation window after property triggering
How Does Moisture Affect the Physical Property of Memristance for Anionic–Electronic Resistive Switching Memories? (2015)

Memristors based on anionic–electronic resistive switches represent a promising alternative to transistor‐based memories because of their scalability and low power consumption. To date, studies on resistive switching have focused on oxygen anionic or electronic defects leaving protonic charge‐carrier contributions out of the picture despite the fact that many resistive switching oxides are well‐established materials in resistive humidity sensors. Here, the way memristance is affected by moisture for the model material strontium titanate is studied. First, characterize own‐processed Pt|SrTiO 3‐ δ |Pt bits via cyclic voltammetry under ambient conditions are thoroughly characterized. Based on the high stability of a non‐volatile device structures the impact of relative humidity to the current–voltage profiles is then investigated. It is found that Pt|SrTiO 3‐ δ |Pt strongly modifies the resistance states by up to 4 orders of magnitude as well as the device's current–voltage profile shape, number of crossings, and switching capability with the level of moisture exposure. Furthermore, a reversible transition from classic memristive behavior at ambient humidity to a capacitively dominated one in dry atmosphere for which the resistive switching completely vanishes is demonstrated for the first time. The results are discussed in relation to the changed Schottky barrier by adsorbed surface water molecules and its interplay with the charge transfer in the oxide.
Softwarization of Radio and Wireless Network (2017)

While SDR and SDN initially were parallel evolutions happening in isolated research communities, several European projects, more specifically the H2020 projects WiSHFUL, eWINE and ORCA are currently developing enablers to bridge the gap between SDR and SDN.These projects offer advanced software and hardware platforms in open stateof theart largescale wireless test facilities that can be used and further extended by academic researchers and wireless developers. MotivationDuring the past decades we have witnessed the explosive emergence of wireless technologies and standards, covering different ranges and different licensed and unlicensed spectral bands.Some trends observed are (1) the everincreasing number and diversity of wireless devices (2) running applications that become more critical and bandwidthhungry, and having very diverging QoS requirements, and (3) the presence of multiple heterogeneous wireless technologies, often integrated in the same device, sharing the same physical environment and in many cases also sharing the same spectral bands.Unfortunately, as the wireless radio spectrum is a scarce resource, the available spectral bandwidth does not scale with the increasing bandwidth demands from wireless devices and applications.There is a hence a need to introduce new sophisticated techniques for accessing and sharing the wireless medium in a highly efficient manner.Such techniques are expected to either improve the coordination within a given spectral band (horizontal spectrum sharing), or explore the possibilities of opportunistically using unused spectrum in underutilized and potentially licensed spectral bands (vertical spectrum sharing, also called dynamic spectrum sharing or DSS).
Interleaved acquisition for cross scatter avoidance in dual cone‐beam CT (2012)

Cross scatter is substantial in dual cone-beam imaging, but its effects can be largely removed by interleaved acquisition, which can be achieved at the same angular sampling rate either by doubling the data acquisition rate or halving the rotation speed.
High Efficiency High Power Blue Laser by Resonant Doubling in PPKTP (2011)

I developed a high power blue laser for use in scientific and technical applications (eg. precision spectroscopy, semiconductor inspection, flow cytometry, etc). It is linearly polarized, single longitudinal and single transverse mode, and a convenient fiber coupled continuous wave (cw) laser source. My technique employs external cavity frequency doubling and provides better power and beam quality than commercially available blue diode lasers. I use a fiber Bragg grating (FBG) stabilized infrared (IR) semiconductor laser source with a polarization maintaining (PM) fiber coupled output. Using a custom made optical and mechanical design this output is coupled with a mode matching efficiency of 96% into the doubling cavity. With this carefully designed and optimized cavity, measurements were carried out at various fundamental input powers. A net efficie ncy of 81 % with an output power of 680 mW at 486 nm was obtained using 840 mW of IR input. Also I report an 87.5 % net efficiency in coupling of blue light from servo locked cavity into a single mode PM fiber. Thus I have demonstrated a total fiber to fiber efficiency of 71% can be achieved in our approach using periodically poled potassium titanyl phosphate (PPKTP). To obtain these results, all losses in the system were carefully studied and minimized.
Resonantly cladding-pumped Yb-free Er-doped LMA fiber laser with record high power and efficiency (2011)

We report the results of our power scaling experiments with resonantly cladding-pumped Er-doped eye-safe large mode area (LMA) fiber laser. While using commercial off-the-shelf LMA fiber we achieved over 88 W of continuous-wave (CW) single transverse mode power at ~1590 nm while pumping at 1532.5 nm. Maximum observed optical-to-optical efficiency was 69%. This result presents, to the best of our knowledge, the highest power reported from resonantly-pumped Yb-free Er-doped LMA fiber laser, as well as the highest efficiency ever reported for any cladding-pumped Er-doped laser, either Yb-co-doped or Yb-free.
The Single Category Implicit Association Test as a measure of implicit social cognition. (2006)

The Single Category Implicit Association Test (SC-IAT) is a modification of the Implicit Association Test that measures the strength of evaluative associations with a single attitude object. Across 3 different attitude domains--soda brand preferences, self-esteem, and racial attitudes--the authors found evidence that the SC-IAT is internally consistent and makes unique contributions in the ability to understand implicit social cognition. In a 4th study, the authors investigated the susceptibility of the SC-IAT to faking or self-presentational concerns. Once participants with high error rates were removed, no significant self-presentation effect was observed. These results provide initial evidence for the reliability and validity of the SC-IAT as an individual difference measure of implicit social cognition.
METAL NANOCLUSTER COMPOSITE SILICATE GLASSES (2007)

Abstract. Composite materials made by metal clusters embedded in silicate glass matrices ex-hibit striking optical properties, interesting for photonic application, as well as important magnetic properties, such as superparamagnetism. These composites are also good candidates for appli-cation in catalysis and sensor technology. Furthermore, metal clusters can act as sensitizers in rare earths-containing glasses, important in telecommunication technology. Among the most inter-esting preparation methods of metal nanocluster composite glasses are those based on ion im-plantation or ion exchange techniques, in combined methodologies that involve also subsequent annealing and/or irradiation of the metal-doped glass matrices. In this work, a short presentation is made of recent developments in the glass composites synthesis that use the combination of differ-ent methods, with special emphasis given to those based on ion implantation and ion exchange techniques. Some example will be also presented, that show the effectiveness of combining differ-ent techniques for controlling the nanocluster structure and size and thus the material features. 1.

Three<i>C. elegans</i>Rac proteins and several alternative Rac regulators control axon guidance, cell migration and apoptotic cell phagocytosis (2001)

The Caenorhabditis elegans genome contains three rac-like genes, ced-10, mig-2, and rac-2. We report that ced-10, mig-2 and rac-2 act redundantly in axon pathfinding: inactivating one gene had little effect, but inactivating two or more genes perturbed both axon outgrowth and guidance. mig-2 and ced-10 also have redundant functions in some cell migrations. By contrast, ced-10 is uniquely required for cell-corpse phagocytosis, and mig-2 and rac-2 have only subtle roles in this process. Rac activators are also used differentially. The UNC-73 Trio Rac GTP exchange factor affected all Rac pathways in axon pathfinding and cell migration but did not affect cell-corpse phagocytosis. CED-5 DOCK180, which acts with CED-10 Rac in cell-corpse phagocytosis, acted with MIG-2 but not CED-10 in axon pathfinding. Thus, distinct regulatory proteins modulate Rac activation and function in different developmental processes.
Use of signal processing algorithms in microprocessor-based control (1986)

This paper reviews the mathematical basis for two popular algorithms - the Kalman filter used in control and the adaptive FIR filter used in signal processing. These estimation algorithms are compared and discussed. They are reformulated into the generalized frequency domain to yield alternative algorithms such as Walsh, Haar, and slant.
