Stability analysis and active stabilization by a centralized stabilizer of Voltage-Source-Rectifier Loads in AC microgrids (2013)

This paper deals with the stability analysis and the active stabilization of Voltage-Source-Rectifier Loads in AC microgrids using a centralized stabilizer. A model of this system is first performed considering the voltage loop dynamics of the rectifier and stability analysis is done using the indirect method of Lyapunov. The stabilizability study realized with Lie algebra shows that the action of an external stabilizer is limited to the AC side of the system. This stabilizer is an inverter only dedicated to the stabilization of the AC bus of the system at the connecting point. To improve the stability area, a feedback control of the stabilizer based on the small-signal theory is developed. A theoretical analysis, simulations and experimental results are presented to evaluate the effectiveness of the proposed method.

Results from transport measurements in individual ${\mathrm{W}}_{x}$V${}_{1\ensuremath{-}x}$O${}_{2}$ nanowires with varying extents of $W$ doping are presented. An abrupt thermally driven metal-insulator transition (MIT) is observed in these wires and the transition temperature decreases with increasing W content at a pronounced rate of $\ensuremath{-}$(48--56) K/at.% W, suggesting a significant alteration of the phase diagram from the bulk. These nanowires can also be driven through a voltage-driven MIT and the temperature dependence of the insulator-to-metal and metal-to-insulator switchings are studied. While driving from an insulator to metal, the threshold voltage at which the MIT occurs follows an exponential temperature dependence [${V}_{\mathrm{TH}\ensuremath{\uparrow}}\ensuremath{\propto}\mathrm{exp}(\ensuremath{-}T/{T}_{0})]$, whereas driving from a metal to insulator, the threshold voltage follows ${V}_{\mathrm{TH}\ensuremath{\downarrow}}\ensuremath{\propto}\sqrt{{T}_{c}\ensuremath{-}T}$ and the implications of these results are discussed.
Cell sheet engineering: a unique nanotechnology for scaffold‐free tissue reconstruction with clinical applications in regenerative medicine (2009)

Cell sheet technology (CST) is based on the use of thermoresponsive polymers, poly(N-isopropylacrylamide) (PIPAAm). The surface of PIPAAms is formulated in such a way as to make its typical thickness <100 nm. In this review, we first focus on how the methods of PIPAAm-grafted surface preparations and functionalization are important to be able to harvest a functional cell sheet, to be further transplanted. Then, we present aspects of tissue mimics and three-dimensional reconstruction of a tissue in vitro. Finally, we give an overview of clinical applications and clinically relevant animal experimentations of the technology, such as cardiomyopathy, visual acuity, periodonty, oesophageal ulcerations and type 1 diabetes.
Cotton-seed treatment with sulphuric acid (1936)

1. Several authors have previously reported that the sulphuric acid treatment of the cotton seed resulted in: ( a ) earlier germination, ( b ) higher percentage of seeds germinating, ( c ) higher yield of seed cotton per acre, and ( d ) better and more uniform planting (this paper is not concerned with the disinfecting effect of this process). 2. A series of experiments, both in the laboratory and under field conditions have been carried out to determine whether the above statements are in agreement with actual experimental data. 3. In so far as the rate of germination is concerned, it was found that: ( a ) untreated seeds often show a smaller percentage of germination than seeds treated with sulphuric acid for various time-intervals, particularly when tested in the laboratory; ( b ) cotton seed treated with the reagent for from 5 min. to 2 hr. or even 5 hr. in some cases, does not show any decrease in its germinative value as determined by laboratory tests. In field trials seeds treated for 5 or 12 hr. practically do not germinate at all, whereas the 2 hr. treatment often shows a small decline in germination; ( c ) an enormous difference in the rate of germination has been revealed between the laboratory determinations on the one hand and the field determinations on the other.
Induction of Tetravalent Protective Immunity Against Four Dengue Serotypes by the Tandem Domain III of the Envelope Protein (2007)

In the present study, the domain IIIs of all four dengue virus (DENV) serotypes were connected sequentially to construct the tandem domain III. The resulting DNA fragment was then cloned into pBAD/Topo ThioFusion plasmid. After induction, the Escherichia coli expression protein was purified and used to immunize BALB/c mice by subcutaneous route. The sera from mice immunized with the purified protein were confirmed to contain specific high antibody titers against DEN1, DEN2, and DEN4, and moderate antibody titer against DEN3. In suckling mouse model, 70% of the mice challenged with DEN1, DEN2, and DEN4 in combination with sera from mice immunized with the purified protein were protected, and 18% of the mice challenged with DEN3 in combination with the same sera were protected. Our data suggest that the tandem domain III of the envelope protein can be used as a potential tetravalent dengue vaccine based on a single antigen.
Immune Response to Group A Streptococcal C5a Peptidase in Children: Implications for Vaccine Development (2003)

The group A streptococcal C5a peptidase (SCPA) is a major surface virulence protein that facilitates the establishment of local infection by group A streptococci (GAS). We measured the human immune response to SCPA, using a standardized indirect enzyme-linked immunosorbent assay. Paired acute and convalescent serum samples from children with GAS-associated pharyngitis were assayed, and a strong immune response to SCPA was demonstrated that was independent of the infecting M type and the age of the patient. Western blot analysis of bacterial extracts revealed that all tested M types expressed SCPA. The immune response to SCPA correlated with the anti-streptolysin O and anti-DNase B responses. These data confirm the immunogenicity of SCPA in humans. Previous knowledge of SPCA's role in virulence, its highly conserved nature, and the results of mouse protection studies make SCPA an ideal vaccine candidate for the prevention of GAS disease.
Status of HCAT/JG-PP Program on Replacement of Hard Chrome Plating With HVOF Thermal Spray Coatings on Landing Gear (2014)

Joint Group on Pollution Prevention (JGPP) are collaborating on executing a program to qualify HVOF thermal spray coatings as a replacement for hard chrome plating in the manufacturing and repair of aircraft landing gear. The Canadian Department of National Defence and Industry Canada are also partners in this effort. A joint test protocol (JTP) has been prepared and approved by the stakeholder organizations, including OEMs and government organizations. Included in the JTP are material tests such as fatigue, wear, corrosion, hydrogen embrittlement and impact, and operational tests on actual components. Results will be presented for a substantial amount of the material testing as well as the results of a rig test on the Navy F/A-18 E/F main landing gear containing several HVOF-coated components and the status of flight testing on Navy P3 and E-6A aircraft containing HVOF-coated landing gear components.

Construction of a hybrid plasmid capable of replication in the bacterium Escherichia coli and the cyanobacterium Anacystis nidulans (1982)

A hybrid plasmid was constructed between the 5.3-megadalton plasmid (pUH24) of Anacystis nidulans R2 and the Escherichia coli plasmid pBR322. This was accomplished by adding a transposon to pBR322 and transforming this DNA into A. nidulans. One resultant hybrid, pLS103, had a molecular weight of 6.8 x 10(6), replicated in both organisms, had unique sites for two restriction endonucleases, conferred ampicillin resistance on both organisms, and could be used as a cloning vector in A. nidulans.
GrabCut in One Cut (2013)

Among image segmentation algorithms there are two major groups: (a) methods assuming known appearance models and (b) methods estimating appearance models jointly with segmentation. Typically, the first group optimizes appearance log-likelihoods in combination with some spacial regularization. This problem is relatively simple and many methods guarantee globally optimal results. The second group treats model parameters as additional variables transforming simple segmentation energies into high-order NP-hard functionals (Zhu-Yuille, Chan-Vese, Grab Cut, etc). It is known that such methods indirectly minimize the appearance overlap between the segments. We propose a new energy term explicitly measuring L1 distance between the object and background appearance models that can be globally maximized in one graph cut. We show that in many applications our simple term makes NP-hard segmentation functionals unnecessary. Our one cut algorithm effectively replaces approximate iterative optimization techniques based on block coordinate descent.
Destruction of Iron-Complexed Cyanide by Alkaline Hydrolysis (1989)

Iron-complexed cyanide compounds are found in various industrial wastes, and are resistant to destruction by conventional technologies used to treat cyanide-bearing wastes. This study evaluated hydrolytic destruction of iron-complexed cyanide in leachates from land disposal of spent carbonanceous material used to line aluminum reduction cells. The investigation showed that iron-cyanide complexes may be hydrolyzed under alkaline conditions at elevated temperatures and pressures, e.g. in the range of 165-180 °C and 100-150 psig. The hydrolysis reaction is apparently first-order with respect to total cyanide. The reaction yields stoichiometric amounts of ammonia and formate, and Fe3O4(s). The rate of the reaction is especially temperature dependent, and for the case of spent potlining leachate, the hydrolysis rate may be estimated by an Arrhenius kinetic expression for hydrolysis of simple cyanide. The rate of the hydrolysis reaction for iron-complexed cyanide is compared to that for other metal-cyanide complexes. It is shown that waste composition may affect the hydrolysis rate, and that the instability of certain metal-cyanide complexes with respect to alkaline chlorination does not correlate with instability with respect to alkaline hydrolysis. Alkaline hydrolysis is an appropriate technology for destruction of iron- and other metal-cyanide compounds in wastes at high concentrations.
A noise-protected digital heart ratemeter (1975)

In many experimental and diagnostic studies of heart rate, a simple averaging ratemeter is not satisfactory. This is due to the difficulty of obtaining an instrument response sufficiently fast to follow the rapid changes in rate, and at the same time keeping the ripple to an acceptable level.This paper describes an instantaneous-frequency cardiotachometer with some unique design features. It focuses particular attention on the digital period-to-frequency converter and a protection system designed to reject spurious noise pulses, such as those caused by muscle artefacts during exercise studies and those occurring during foetal heart rate monitoring.
A survey on adaptive qualitative assessment and dynamic questions generation approaches (2010)

The goal of assessment is to identify weaknesses in learner's knowledge. There are various types of assessment in which among them are the Quantitative and Qualitative assessment. This paper is concerned with the qualitative assessment. The underlying principle of qualitative assessment motivates the research. Qualitative assessment is not about assessing the domain knowledge but it is about assessing the learner's current and potential capacities related to the knowledge. Dynamic questions generation for qualitative assessment involves a strong degree of subjectiveness. Appropriate scoring mechanism is needed to assess learner's level of knowledge and to dynamically create a subjective question that is adaptive to the learner's current knowledge and understanding. The paper provides an overview of adaptive qualitative assessment and dynamic questions generation and a discussion on possible approaches found in the recent research as a guide to the development of an automated tool.
Molecular cloning of a proteolytic antibody light chain. (1994)

The cDNA for an antibody light chain raised by immunization against vasoactive intestinal peptide (VIP) was cloned in a bacterial expression vector, and the recombinant light chain was purified to electrophoretic homogeneity. The light chain catalyzed the hydrolysis of VIP efficiently owing to its comparatively high affinity for the substrate. In control experiments, the catalytic activity was preserved at a constant level after further chromatography of the light chain on anion-exchange and gel-filtration fast protein liquid chromatography columns, and it was removed by immunoadsorption with immobilized anti-mouse light chain antibody. The amide bond linking methylcoumarinamide (MCA) and arginine in a tripeptide unrelated in sequence to VIP was cleaved by the light chain with lower affinity and kinetic efficiency (kcat/Km). Hydrolysis of the peptidyl-MCA conjugate was inhibited competitively by the alternate substrate, VIP. The Ki and Km values for VIP were in the same range, indicating that peptide-MCA and VIP hydrolysis occurs at a common catalytic site in the light chain. Molecular modeling suggested the presence of a serine protease-like site in the light chain. This was supported by inhibition of the hydrolytic activity by serine protease inhibitors, but not by inhibitors of other classes of proteases. These observations suggest a poorly discriminatory catalytic site, with specificity for VIP arising chiefly by means of the antigen recognition function of the light chain combining site.
Hematological adverse events of sunitinib in treatment of advanced renal cell carcinoma (2012)

Objective To evaluate the hematological adverse events of sunitinib in treatment of advanced renal cell carcinoma.Methods Forty-four male patients and 18 female patients were included in this study.They were all with metastatic renal cell carcinoma and received sunitinib treatment at the dose of 50 mg daily in repeated 6 weeks cycle (4 weeks on and 2 weeks off).Toxicity was assessed every cycle with tumor assessments every 2 cycles via CT or PET-CT.Results Fifty patients (80.6％) had experienced treatment-related hematotoxicity,including leucocytopenia,anemia and thrombocytopenia.Severe hematological adverse events ( grade 3 -4 ) occured in 18 patients ( 29.0％ ) and slight events ( grade 1 - 2 ) in others (51.6％).Most of the hematological adverse events were manageable and reversible and treatment-changes (dose reduction,interruption) were necessary in severe cases.Almost half of the dose reduction (9/21,42.9％ ) were owing to hematotoxicity.Conclusions Sunitinib of 50 mg dose on schedule 4/2 is effective and well-tolerated in advanced renal carcinoma patients.Hematological adverse events are frequent in Chinese patients and can be controlled well.

Form-Factors for General Environments (1988)

A new algorithm, based on the hemi-cube formulation, which calculates the form-factors required by the solution of the rendering equation, is presented. The concept of form-factors of the standard radiosity method is developed, In particular, the concept of specular form-factors is proposed. These new form-factors are also purely geometric terms describing the transfer of energy from one surface to another within a non-diffuse environment. The new form-factor is evaluated by numerical integrations based on the hemi-cube algorithm. The equations of the effective diffuse radiosity are presented and solved by numerical methods. The extension fully develops the characteristic of radiosity method and successfully solves the view-independent energy transfer in a general environment.
Coding with digits of unequal cost (1995)

At present, optimal coding for a noiseless digital channel with digits of unequal cost requires solving a large linear programming problem. Much simpler procedures give codes, resembling Shannon's (1948) and Huffman's, that are found close to optimal in tests with typical sources and channels.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Distributed contention-free traffic scheduling in IEEE 802.11 multimedia networks (2003)

Wireless local area networks are a promising solution to support advanced data services in mobile environments. The IEEE 802.11 wireless LAN standard is emerging as a mature technology to support delay sensitive network services. In order to support these services the standard has proposed the use of a polling scheme; however, existing polling schemes require high communication overheads or suffer from unfairness. In this paper, we propose a distributed fair queueing algorithm "distributed deficit round robin", which is compatible with the 802.11 medium access control rules. Software simulation of this scheme shows that it can manage a heterogeneous mix of delay sensitive traffic.
A randomized trial of choice of treatment in prostate cancer: the effect of intervention on the treatment chosen (2003)

Design of an artificial muscle actuated finger towards biomimetic prosthetic hands (2006)

This paper focuses on the design and modeling of a prosthetic finger for children. Conventional prosthetic hands are simple grippers that only restore the very basic grasping capabilities of the human hand. Novel design methodologies are required in order to address the issue of low functionality of prosthetic hands while still meeting their mass and size requirements. We propose a biomimetic approach to prosthetic hand design. The musculoskeletal characteristics of the human hand are studied in order to extract elements that are essential in the design of a biomechanically accurate hand. This paper presents a 4 DOF finger design that closely mimics the size and kinematics of the human finger. Our design proposes to use SMA-driven tendon wires that are directly attached to the finger structure, in a manner similar to the natural tendons and muscles. A kinematic analysis of the proposed finger, which defines the relationship between the motion of its joints and the corresponding SMA artificial muscle contraction ranges, is presented. The results of a torque analysis, carried out to evaluate SMA wire diameter and actuation forces required, is also presented
Treatment With the Radiolabeled Somatostatin Analog [ <sup>177</sup> Lu-DOTA <sup>0</sup> ,Tyr <sup>3</sup> ]Octreotate: Toxicity, Efficacy, and Survival (2008)

Treatment with [(177)Lu-DOTA(0),Tyr(3)]octreotate has few adverse effects. Tumor response rates and progression-free survival compare favorably to the limited number of alternative treatment modalities. Compared with historical controls, there is a benefit in OS from time of diagnosis of several years.

A shear force feedback control system for near-field scanning optical microscopes without lock-in detection (1997)

An improvement to the currently used ac impedance detection method for tip-sample distance control in near-field scanning optical microscopes is described and demonstrated. The output signal of the electronic bridge is increased by a factor of 5000 so that a root-mean-square chip can be used in place of sensitive lock-in detection. It is shown that the signal-to-noise ratio of this new method is high enough to detect 0.07 nm changes in topography. In addition, this modification makes the electronics for the shear force feedback compact and inexpensive.

Synthesis and anticonvulsant properties of 1,2,3,4-tetrahydroisoquinolin-1-ones (2004)

Following our previous molecular modeling studies we herein report the synthesis of substituted 1,2,3,4-tetrahydroisoquinolinone-4-carboxylic acids in an attempt to obtain new anticonvulsants acting as negative modulators of AMPA-type glutamate receptor. The evaluation of their pharmacological effects demonstrated that some derivatives were able to prevent audiogenic induced seizures in DBA/2 mice.
Fluorocarbon-based single-layer resist for 157-nm lithography (2002)

We have designed and synthesized a number of unique polymer systems composed of acrylate and styrene even though it had moderate transparency. Our first model of 157nm photoresist was based on a (alpha) trifluoromethylacrylate and styrene bearing a pendent hexafluoroisopropanol with pentafluoroisopropyl t-butyl carbonate (PFITBC) as the transparent enhancer and acid labile compound. PFITBC was obtained from perfluorinated enolate with di-t-butyl carbonate with high yield. All of the absorbance of our system ranged over 3.0~3.4micrometers <SUP>-1</SUP> for base resin, which corresponded to a resist thickness of 110~125 nm at the optical density of 0.4. We have formulated several resists based on these polymers and these formulations have shown high resolution and contrast at 248 nm. We were able to obtain 240nm 1:1 image when exposed at 248 nm by a Nikon stepper with 0.45NA. To overcome the weak etch resistance with thin thickness film, we investigated the vapor phase silylation treatment (SILYAL) in which the treated pattern was more persistent against the O<SUB>2</SUB> plasma and turned to smoother surface. DMSMDA with Bi(DMA)MS of 30-40 wt% showed not only good control resist flow but also the improvement of line-edge roughness. Our results suggested that a facile approach to fluorine incorporated resin with SILYAL process can accelerate the 157nm lithography.
