The influence of age-related cataract on blue-on-yellow perimetry. (1995)

Cataract predominantly causes a general reduction in B-Y sensitivity. Caution therefore needs to be exercised in the interpretation of the B-Y visual field in patients in whom glaucoma and cataract coexist.
Effect of Etanercept, a Tumor Necrosis Factor-Alpha Inhibitor, on Neuropathic Pain in the Rat Chronic Constriction Injury Model (2008)

This preclinical study indicates that delivering TNF-alpha inhibitors by means of a locally administered polymeric formulation provides long-lasting analgesia in an inflammatory neuropathic pain model.
The study of tracking control of a robotic manipulator actuated by shape memory alloy (2008)

Shape memory alloy (SMA) composites offer a great potential as actuators because of its excellent power to weight ratio, smooth motion and silent actuation. However, SMA actuated robotic manipulator systems have severe hysteresis, system nonlinearities, model and parametric uncertainties those are often responsible for position inaccuracy in a regulation or tracking system. A simple and upstanding control algorithm for tracking control of a SMA actuated robotic manipulator system is presented in this paper. The controller is developed based on the combination of a variable structure control approach and a heuristic based intelligent control approach like fuzzy logic control (FLC), so that the resulting control algorithms have a superior performance both in stabilization and tracking the desired trajectories. A desktop prototype of the robotic manipulator system is recalled from our previous work. A nonlinear form of proportional-integral-derivative (PID) controller is also employed to the system for comparison of performance. Several experiments have been performed in tracking both stationary and periodically varied input signals. Experimental results from real time control verify the effective and robust performance of the controller.

X-Band acquisition aid antenna for ground stations application (2010)

This paper describes the design and operational validation of the X-Band acquisition aid system (XAA) installed and used in the ESTRACK LEOP network. The purpose of this acquisition aid antenna is to provide a wider X-band beam than the 15m main antenna during the first critical acquisition phase after orbit injection. The paper describes the design and performances of the most important components as well as of the complete antenna. An XAA prototype was manufactured and installed within the ESA ground station in Perth, Western Australia. Operational validation of the system has been successfully achieved in the frame of the Herschel-Plank LEOP campaign in May 2009. A second XAA antenna was installed in 2009 in Kourou (French Guyana) and a third one will be deployed in Maspalomas (Canary Islands) in 2010. These three terminals will provide the core support to the Lisa Pathfinder LEOP.
On coil–stretch transitions in dilute polymer solutions (1989)

In this paper we examine molecular stretching in the inception of uniaxial elongational flow of dilute polymer solutions. The polymer molecules are modeled as bead–spring chains with finitely extensible nonlinear elastic springs, and we use the Peterlin approximation. This work is distinguished from earlier work because we model the macromolecules with chains instead of dumbbells, and we examine the time dependence of three average quantities describing the chain conformation in unsteady flows: root-mean-square end-to-end distance, root-mean-square extensions of the individual links, and mean moment of inertia about the axis of elongation. We observe a gradual transition from the coiled equilibrium state of the chain to the stretched state after the inception of strong uniaxial elongational flow, and we describe the nature of this transition which takes place in roughly four stages: I equilibrium coil; II deformed coil; III spring stretched (‘‘locally unraveled’’); and IV unfolded chain. Inclusion of hydrodynamic interaction changes the macromolecular response quantitatively but not qualitatively.
Update on therapies for acute ischemic stroke (2000)

Acute ischemic stroke is now considered a neurological emergency for which there are new therapies. Neurosurgeons and neurologists need to remain apprised of advances in this field. The authors discuss approved and emerging therapies for patients suffering from acute ischemic stroke, based on a review of recent publications. Currently, intravenous tissue-type plasminogen activator is the only Food and Drug Administration-approved therapy for acute ischemic stroke. Intraarterial delivery of thrombolytics is a promising treatment and may be effective in selected patients. Other therapies for acute cerebral ischemia are intriguing but still in the investigational stages.
Possible Role of <i>Streptococcus pyogenes</i> in Mucocutaneous Lymph Node Syndrome. XV. Potential Utility of Streptococcal Pyrogenic Exotoxin Toxoid for the Prophylaxis and Treatment of MCLS (1992)

Mice made tolerant to streptococcal pyrogenic exotoxin (SPE) by neonatal inoculation with SPE emulsified in incomplete Freund's adjuvant demonstrated early thrombocytopenia followed by thrombocytosis. This state is the perfect counterpart of patients with mucocutaneous lymph node syndrome (MCLS). We have hypothesized that by inducing tolerance to SPE, the biological activities of the toxin might play leading roles in the pathogenesis of MCLS. In the present investigations, the efficacy of SPE on the prophylaxis and treatment of diseases caused by Streptococcus pyogenes (including MCLS) were monitored using the murine model system accompanied with a platelet-counting technique. The mice, rendered tolerant due to neonatal SPE inoculation and followed by immunization with SPE toxoid about 1 month prior to the provocative injections with SPE, demonstrated an almost complete lack of response to the provocation, keeping platelet counts within the normal range of values (except for a marginally significant thrombocytosis 7 days postprovocation). Moreover, anti-SPE titers of the sera from the mice sacrificed on day 35, at which point the observation was terminated, were proved to be markedly elevated when compared with controls. These findings seem to suggest that immunization with the toxoid could overcome tolerance, resulting in the production of an antitoxin. In a second experiment that examined the effect of administration with rabbit antiserum raised against the toxoid, the antiserum-treated mice demonstrated a transitory thrombocytosis on 7 days postprovocation with SPE, followed by an abrupt decrease in the number of platelets from day 10 onward.(ABSTRACT TRUNCATED AT 250 WORDS)
CLOAKING AND INVISIBILITY: A REVIEW (Invited Review) (2014)

Invisibility has been a tantalizing concept for mankind over several centuries. With recent developments in metamaterial science and nanotechnology, the possibility of cloaking objects to incoming electromagnetic radiation has been escaping the realm of science fiction to become a technological reality. In this article, we review the state-of-the-art in the science of invisibility for electromagnetic waves, and examine the different available technical concepts and experimental investigations, focusing on the underlying physics and the basic scientific concepts. We discuss the available cloaking methods, including transformation optics, plasmonic and mantle cloaking, transmission-line networks, parallel-plate cloaking, anomalous resonance methods, hybrid methods and active schemes, and give our perspective on the subject and its future. We also draw a parallel with cloaking research for acoustic and elastodynamic waves, liquid waves, matter waves and thermal flux, demonstrating how ideas initiated in the field of electromagnetism have been able to open groundbreaking venues in a variety of other scientific fields. Finally, applications of cloaking to non-invasive sensing are discussed and reviewed.
Study of Improved Aluminum Materials for Vehicular Armor (1977)

An Intermediate Thermal Mechanical Treatment (ITMT), consisting of warm rolling at 500 F followed by a recrystallization treatment, produced a fine-grained, relatively equiaxed, recrystallized structure in 7475 plate. Alloy 7475-T6 plate having this recrystallized structure (AR) had slightly lower strengths and fracture toughness and higher ductility (tensile reduction in area) than laboratory or commercial hot rolled 7475-T6 plate having an unrecrystallized structure. Alloy 7475-T6, similarly processed to a fine- grained, recrystallized structure, then hot rolled 25% at 750 F (AR and HR) had (1) strengths similar to laboratory and commercial hot rolled 7475-T6 plate, (2) fracture toughness similar to commercial hot rolled 7475-T6 plate but slightly lower than laboratory hot rolled 7475-T6 plate, and (3) ductility higher than laboratory or commercial hot rolled 7475-T6 plate. The fracture toughness of both the recrystallized (AR) and the recrystallized plus hot rolled (AR and HR) 7475-T6 plate was significantly higher than the fracture toughness of conventionally processed commercial 7075-T651 plate. Application of Final Thermal Mechanical Treatment (FTMT) practices to 7475 plate produced strength/ toughness relationships generally superior to that of 7075-T651 plate. (Author)

Site-Directed Alkylation of Cysteine Replacements in the Lactose Permease of <i>Escherichia coli</i> :  Helices I, III, VI, and XI (2006)

To complete a study on site-directed alkylation of Cys replacements in the lactose permease of Escherichia coli (LacY), the reactivity of single-Cys mutants in helices I, III, VI, and XI, as well as some of the adjoining loops, with N-[14C]ethylmaleimide (NEM) or methanethiosulfonate ethylsulfonate (MTSES) was studied in right-side-out membrane vesicles. With the exception of several positions in the middle of helix I, which either face the bilayer or are in close proximity to other helices, the remaining Cys replacements react with the membrane-permeant alkylating agent NEM. In helices III and XI, most Cys replacements are also alkylated by NEM except for positions that face the bilayer. The reactivity of Cys replacements in helix VI is noticeably lower and only 45% of the replacements label. Binding of sugar leads to significant increases in the reactivity of Cys residues that are located primarily at the same level as the sugar-binding site or in the periplasmic half of each helix. Remarkably, studies with small, impermeant MTSES show that single-Cys replacements in the cytoplasmic portions of helices I and XI, which line the inward-facing cavity, are accessible to solvent from the periplasmic surface of the membrane. Moreover, addition of ligand results in increased accessibility of Cys residues to the aqueous milieu in the periplasmic region of the helices, which may reflect structural rearrangements leading to opening of an outward-facing cavity. The findings are consistent with the X-ray structure of LacY and with the alternating access model [Abramson, J., Smirnova, I., et al. (2003) Science 301, 610-615].
Peroxidative Activity of Apple Peel in Relation to Development of Poststorage Disorders (1995)

Among the lipid peroxidation reactions, the addition of molecular O 2 to polyunsaturated fatty acids (PUFAs) is of particular interest in biological systems. The lipoxygenase pathway is the most-studied enzymatic pathway for oxidizing PUFAs, but nonenzymatic reactions have also been characterized. When one considers the significance of lipid peroxidation, it is surprising to discover the many diverse areas that are affected. In fact, whether one considers the process beneficial or detrimental depends on the circumstances. In situations where lipid peroxidation has been implicated in tissue damage, controversy exists over whether it is involved in the primary events causing injury or merely a by-product.
Design requirements for more flexible structured editors from a study of programmers' text editing (2005)

A detailed study of Java programmers' text editing found that the full flexibility of unstructured text was not utilized for the vast majority of programmers' character-level edits. Rather, programmers used a small set of editing patterns to achieve their modifications, which accounted for all of the edits observed in the study. About two-thirds of the edits were of name and list structures and most edits preserved structure except for temporary omissions of delimiters. These findings inform the design of a new class of more flexible structured program editors that may avoid well-known usability problems of traditional structured editors, while providing more sophisticated support such as more universal code completion and smarter copy and paste.
Thermoresponsive Vesicular Morphologies Obtained by Self-Assemblies of Hybrid Oligosaccharide-<i>block</i>-poly(<i>N</i>-isopropylacrylamide) Copolymer Systems (2009)

This work discusses the self-assembly properties of thermoresponsive hybrid oligosaccharide-block-poly(N-isopropylacrylamide) copolymer systems: maltoheptaose-block-poly(N-isopropylacrylamide) (Mal(7)-b-PNIPAM(n)) copolymers. Those systems at different molar masses and volume fractions were synthesized using Cu(I)-catalyzed 1,3-dipolar azide/alkyne cycloaddition, so-called "click" chemistry, between an alkynyl-functionalized maltoheptaose (1) and poly(N-isopropylacrylamide) having a terminal azido group (N(3)-PNIPAM(n)) prepared by atom transfer radical polymerization (ATRP). While the cloud point (T(cp)) of the N(3)-PNIPAM(n) ranged from 36.4 to 51.5 degrees C depending on the degree of polymerization, those obtained of the diblock copolymers ranged from 39.4 to 73.9 degrees C. The self-assembly of such systems is favored due to the hydrophobicity of the PNIPAM in water above the T(cp). While the N(3)-PNIPAM(n) present polydisperse globular shape with a mean diameter of 500 nm, well-defined vesicular morphologies with an approximate diameter of 300 nm are obtained in diblock copolymer systems. These results were obtained and confirmed using static and dynamic light scattering as well as imaging techniques such as transmission electron microscope experiments.
Evaluation of Impressed Current Cathodically Protected API 650 Tank Bottoms in the Presence of Vapor Phase Corrosion Inhibitor (2016)

Abstract This work aims to assess the effectiveness of amine carboxylate based Vapor Phase Corrosion Inhibitor (VPCI) on the protection of storage tank bottoms against soil-side corrosion, as standalone and in combination with Impressed Current Cathodic Protection (ICCP) system. It also attempts to determine the effect of VPCI on instant-off potential. Lab-scale tanks simulating the environment of single bottom storage tank sitting on washed sand with High-density polyethylene (HDPE) liner and ICCP system were considered. Corrosion rate for each tank was monitored using Electrical Resistance (ER) probe corrosion monitoring system. Natural and instant-off potentials of tank bottoms' steel plates were also monitored throughout the experiment using temporary Copper/Copper-Sulfate (Cu/CuSO4) reference electrode. Corrosion rate data from ER probes indicated that amine carboxylate VPCI slurry is effective in mitigating corrosion on carbon steel bottom plates. The corrosion rate was reduced by 82.5% and 89.7% as standalone and in combination with ICCP respectively. The study also indicated a shift of the instant-off potential, which might need to be considered by CP operators in the case of using VPCI in supplementing ICCP for protection of storage tank bottoms.

Porphyrin-Mediated Binding to Hemoglobin by the HA2 Domain of Cysteine Proteinases (Gingipains) and Hemagglutinins from the Periodontal Pathogen<i>Porphyromonas gingivalis</i> (1999)

Heme binding and uptake are considered fundamental to the growth and virulence of the gram-negative periodontal pathogen Porphyromonas gingivalis. We therefore examined the potential role of the dominant P. gingivalis cysteine proteinases (gingipains) in the acquisition of heme from the environment. A recombinant hemoglobin-binding domain that is conserved between two predominant gingipains (domain HA2) demonstrated tight binding to hemin (Kd = 16 nM), and binding was inhibited by iron-free protoporphyrin IX (Ki = 2.5 microM). Hemoglobin binding to the gingipains and the recombinant HA2 (rHA2) domain (Kd = 2.1 nM) was also inhibited by protoporphyrin IX (Ki = 10 microM), demonstrating an essential interaction between the HA2 domain and the heme moiety in hemoglobin binding. Binding of rHA2 with either hemin, protoporphyrin IX, or hematoporphyrin was abolished by establishing covalent linkage of the protoporphyrin propionic acid side chains to fixed amines, demonstrating specific and directed binding of rHA2 to these protoporphyrins. A monoclonal antibody which recognizes a peptide epitope within the HA2 domain was employed to demonstrate that HA2-associated hemoglobin-binding activity was expressed and released by P. gingivalis cells in a batch culture, in parallel with proteinase activity. Cysteine proteinases from P. gingivalis appear to be multidomain proteins with functions for hemagglutination, erythrocyte lysis, proteolysis, and heme binding, as demonstrated here. Detailed understanding of the biochemical pathways for heme acquisition in P. gingivalis may allow precise targeting of this critical metabolic aspect for periodontal disease prevention.
An Excitation Model for HMM-Based Speech Synthesis Based on Residual Modeling (2007)

This paper describes a trainable excitation approach to eliminate the unnaturalness of HMM-based speech synthesizers. During the waveform generation part, mixed excitation is constructed by state-dependent filtering of pulse trains and white noise sequences. In the training part, filters and pulse trains are jointly optimized through a procedure which resembles analysis-bysynthesis speech coding algorithms, where likelihood maximization of residual signals (derived from the same database which is used to train the HMM-based synthesizer) is pursued. Preliminary results show that the novel excitation model in question eliminates the unnaturalness of synthesized speech, being comparable in quality to the the best approaches thus far reported to eradicate the buzziness of HMM-based synthesizers.
Collection Efficiency Calculation in the Weak Electric Field Limit of Scanning Electron Microscopes (SEM) and Its Application to SEM Image Generation (1988)

Collection efficiencies of secondary electrons in SEM are analyzed theoretically in the weak electric field limit. Collection efficiency is determined by the amount of secondary electrons which can reach the electron detectors. The effects of the screening of local topographies around the incident points are analyzed in order to calculate this collection efficiency. We constructed a weak electric field limit model based on simple assumptions including (1) straight motion of emitted electrons near the sample surface, (2) complete absorption of once-blocked electrons, (3) full detection of emitted electrons departed from the near neighbor of the sample surface. In some special cases, collection efficiencies are calculated analytically. We generated a few SEM images combining them with a model of the secondary electron yield.
A planar chart equivalent to Poincaré sphere for expressing state-of-polarization of light (1986)

A planar chart for expressing a state of polarization of an arbitrarily polarized light is proposed. The proposed chart is equivalent to the Poincaré sphere, but has an advantage over the Poincaré sphere in that it can be printed on a flat paper. The characteristics of the proposed chart are investigated. The computer-drawn exact chart is shown with important parameter values. Finally, an example of the application of the proposed chart is described.
A practical guide to tune of proportional and integral (PI) like fuzzy controllers (2003)

A method for tuning a PI-like fuzzy controller is proposed. The relationship between parameters and performance of the fuzzy controller is discussed. This includes defining the relationships between parameters and control performance, which parameters are more important and which are less important, which parameters should be tuned first and which later, and in which direction parameters should be adjusted. The result is a guide for tuning fuzzy control systems.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
