Constant Speed 400 Hz Aircraft Electric Generation System (1979)

<div class="htmlview paragraph">The purpose of this paper is to examine recent innovations in the state-of-the-art of aircraft constant speed drive alternating current electric power generation systems. An engineering problem was posed by the concepts used in designing the latest generation of commercial aircraft. The approach to solving the problem and the solutions chosen have offered the opportunity to further increase the reliability of the aircraft secondary power system. The maintenance required has been decreased by simplifying the system, and much of the error potential involved in fault isolation has been eliminated by a reliable Built-In Test (BITE) system.</div>

Investigation of Simulated Annealing, Ant-Colony Optimization, and Genetic Algorithms for Self-Structuring Antennas (2004)

A self-structuring antenna (SSA) is capable of arranging itself into a large number of configurations. Because the properties of the configurations are generally unknown at the onset of operation, efficient search algorithms are required to find suitable configurations for a given set of environmental and operational conditions. This paper investigates the use of ant-colony optimization, simulated annealing, and genetic algorithms for finding suitable antenna states. The implementation of each algorithm for SSA searches is described, and the performance of each algorithm is compared to a random search.
Exercise, MAPK, and NF-κB signaling in skeletal muscle (2007)

Mitogen-activated protein kinases (MAPKs) and NF-kappaB are two major regulators of gene transcription and metabolism in response to oxidative, energetic, and mechanical stress in skeletal muscle. Chronic activation of these signaling pathways has been implicated in the development and perpetuation of various pathologies, such as diabetes and cachexia. However, both MAPK and NF-kappaB are also stimulated by exercise, which promotes improvements in fuel homeostasis and can prevent skeletal muscle atrophy. This review will first discuss the major MAPK signaling modules in skeletal muscle, their differential activation by exercise, and speculated functions on acute substrate metabolism and exercise-induced gene expression. Focus will then shift to examination of the NF-kappaB pathway, including its mechanism of activation by cellular stress and its putative mediation of exercise-stimulated adaptations in antioxidant status, tissue regeneration, and metabolism. Although limited, there is additional evidence to suggest cross talk between MAPK and NF-kappaB signals with exercise. The objectives herein are twofold: 1) to determine how and why exercise activates MAPK and NF-kappaB; and 2) to resolve their paradoxical activation during diseased and healthy conditions.
Organic two‐dimensional templates for the fabrication of inorganic nanostructures: Organic/inorganic superlattices (1996)

The self‐organization of inorganic precursors in predetermined patterns is the first step towards the ability to synthesize mesoscopic inorganic materials. Several techniques are described, including the immobilization of inorganic precursors by coordination with bilayer ligands (see figure), which led, for example, to a novel Cd 4 Br 12 S cluster. Finally, the formation of organic/inorganic superlattices is outlined. magnified image
Targeted therapeutic approach for an anaplastic thyroid cancer <i>in vitro</i> and <i>in vivo</i> (2008)

Anaplastic thyroid carcinoma (ATC) is among the most aggressive human malignancies, being responsible for the majority of thyroid cancer-related deaths. Despite multimodal therapy including surgery, chemotherapy, and radiotherapy, the outcome of ATC is poor. The human ATC cell line MB1, derived from tumor tissue of a 57-year-old man with thyroid cancer and pronounced neutrophilia, was established from surgically excised tumor tissue. The karyotype of the cell line shows many chromosomal abnormalities. Preclinical investigations have shown antitumor activity and effectiveness of the BRAF kinase inhibitor Sorafenib and the proteasome inhibitor Bortezomib. After establishment of the MB1 cell line these agents were applied in vitro and, showing activity in a cell culture model, were also used for in vivo treatment. Sorafenib had some clinical effect, namely normalization of leucocytosis, but had no sustained impact on subsequent tumor growth and development of distant metastasis. Molecular diagnostics of the tumor demonstrated no BRAF mutations in exons 11 and 15 concordant with a rather modest effect of Sorafenib on MB1 cell growth. Clinical benefit was seen with subsequent bortezomib therapy inducing a temporary halt to lymph node growth and a progression-free interval of 7 weeks. Our observations together with previous data from preclinical models could serve as a rationale for selecting those patients suffering from ATC most likely to benefit from targeted therapy. A prospective controlled randomized trial integrating kinase and proteasome inhibitors into a therapeutic regime for ATC is warranted.
<i>Tau</i>Gene Mutation K257T Causes a Tauopathy Similar to Pick's Disease (2000)

Exonic and intronic mutations in Tau cause neurodegenerative syndromes characterized by frontotemporal dementia and filamentous tau protein deposits. Here we describe a K257T missense mutation in exon 9 of Tau. The proband, a 47-yr-old male, presented with severe personality changes followed by semantic memory loss. A diagnosis of Pick's disease was made. The symptoms progressed until death at age 51. The proband's brain showed a marked frontotemporal atrophy that was most pronounced in the temporal lobes. Numerous tau-immunoreactive Pick bodies were present in the neocortex and the hippocampal formation, as well as in some subcortical brain regions. Their appearance and staining characteristics were indistinguishable from those of sporadic Pick's disease. Diffuse staining for hyperphosphorylated tau was also observed in some nerve cell bodies. Immunoblot analysis of sarkosyl-insoluble tau showed 2 major bands of 60 and 64 kDa and 2 very minor bands of 68 and 72 kDa. Upon dephosphorylation, these bands resolved into 6 bands consisting of 3-repeat and 4-repeat tau isoforms, with an overall preponderance of 3-repeat tau. Isolated tau filaments were narrow, irregularly twisted ribbons. Biochemically, recombinant tau proteins with the K257T mutation showed a reduced ability to promote microtubule assembly, suggesting that this may be the primary effect of the mutation. In addition, the K257T mutation was found to stimulate heparin-induced assembly of 3-repeat tau into filaments. Taken together, the present findings indicate that the K257T mutation in Tau can cause a dementing condition similar to Pick's disease.
A commit protocol for checkpointing transactions (2003)

A commit protocol is described for checkpointing distributed transactions. Commit protocols are used by distributed transaction management systems to ensure that the multiple nodes participating in a distributed transaction will commit or abort together. This commit protocol is different from others in that a process executing on behalf of a transaction can be interrupted and restarted at some previous snapshot of its state (a checkpoint). The commit protocol guarantees that processes working on behalf of a distributed transaction will be consistent, which implies that the work performed by a restarted process between the time of the checkpoint and the time of the interruption will be undone automatically. The undoing includes any local state changes during that period of time, and any state changes in other processes due to communication with the restarted process in that period. The use of a commit protocol for recovery purposes allows normal execution to be resumed before recovery is completed. Recovery will be carried out in parallel, and the commit protocol guarantees that it is performed eventually. A novel approach of reusing portions of a transaction reduced lost work.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Optimizing Polymer Tandem Solar Cells (2009)

Optimized tandem solar cells based on wide-and small-bandgap polymer semiconductor cells reach an efficiency of 4.9%. In this tandem cell the short-circuit current exceeds that of the current-limiting subcell. The recombination layer that connects the two subcells does not impose important losses.
[Pre-ejection period controlled cardiac pacemaker]. (1989)

Numerous investigations have been performed in search for suitable parameters for physiologic adaptation of the pacing rate. In case of chronotropic incompetence corporeal as well as cardiac control parameters permit open or closed loop control of the pacing rate. Criteria to be considered are the patient's condition, the response time of the system, the proportionality to the oxygen uptake and the susceptibility to interference. A high specificity of the rate response is particularly important for the patient with a low cardiac reserve. The use of a parameter relating to the central hemodynamics, such as the systolic time intervals, particularly the pre-ejection period (PEP), as input signal for rate control is, therefore, of special interest. The concept presented of a PEP-controlled rate adaptive pacemaker is based on the linear proportionality between PEP and the cardiac cycle length. Changing with the sympathetic tone, the PEP permits adaptation of the pacing rate in response to physical as well as emotional stress. The right ventricular PEP parallels the left ventricular one and is measured between the electrode tip and the pacemaker housing. Clinical results obtained confirm the high sensitivity and specificity of this control parameter with respect to the metabolic demand. Technical details of an implantable multiprogrammable device are dealt with.
Electrochemical Reduction of High Pressure  CO 2 on Ni Electrodes (1993)

The electrochemical reduction of under high pressures of was investigated on Ni electrodes. With an increase in pressure, the Faradaic efficiency for reduction was increased while that of evolution by water reduction was decreased. Current density at −1.8 V vs. did not depend greatly on pressure at 30°C. By increasing temperature, the Faradaic efficiency for hydrocarbon formation was increased, suggesting that thermal activation was needed, although the total reduction efficiency for reduction was decreased. The Faradaic efficiency for the hydrocarbon formation showed a maximum at −1.6 V , while those for and were increased with increasing cathodic polarization. The weight distribution of hydrocarbons formed on Fe, Co, and Ni electrodes agreed well with the Schultz‐Flory distribution, indicating that hydrocarbons were formed via a mechanism similar to a Fischer‐Tropsch reaction for thermal catalysis, i.e., polymerization of surface carbene groups produced by the reduction of which was formed by reduction.
Visual Speech Recognition and Utterance Segmentation Based on Mouth Movement (2007)

This paper presents a vision-based approach to recognize speech without evaluating the acoustic signals. The proposed technique combines motion features and support vector machines (SVMs) to classify utterances. Segmentation of utterances is important in a visual speech recognition system. This research proposes a video segmentation method to detect the start and end frames of isolated utterances from an image sequence. Frames that correspond to `speaking' and `silence' phases are identified based on mouth movement information. The experimental results demonstrate that the proposed visual speech recognition technique yields high accuracy in a phoneme classification task. Potential applications of such a system are, e.g., human computer interface (HCI) for mobility-impaired users, lip-reading mobile phones, in-vehicle systems, and improvement of speech-based computer control in noisy environments.
Symmetrical and Asymmetrical Cyanine Dyes. Synthesis, Spectral Properties, and BSA Association Study (2014)

New cyanines were prepared by an efficient and practical route with satisfactory overall yield from low-cost starting materials. The photophysical behavior of the cyanines was investigated using UV-vis and steady-state fluorescence in solution, as well as their association with bovine serum albumin (BSA) in phosphate buffer solution (PBS). No cyanine aggregation was observed in organic solvents or in phosphate buffer solution. The alkyl chain length in the quaternized nitrogen was shown to be fundamental for BSA detection in PBS in these dyes.
CSEM exploration in the Barents Sea: Joint CSEM & seismic interpretation (2013)

While seismic has a superior structural resolution and issensitive to porosity and the presence of hydrocarbons, ithas very little sensitivity to saturation. Controlled-sourceelectromagnetic (CSEM) is, on the other hand, sensitive tohydrocarbon saturation. Thus, joint interpretation ofseismic and CSEM inversion results offer a great potentialfor hydrocarbon saturation and volume estimations. Wedescribe a new workflow employing high resolutiondeterministic CSEM inversion and statistical seismic AVOinversion that applies in an exploration setting, i.e. withoutprior assumptions of the background resistivities or theexistence, sizes and shapes of resistive anomalies. Thehigh resolution deterministic CSEM inversion has provenbetter depth placements and more confined resistiveanomalies by incorporating seismic horizons into theinversion. We use a statistical AVO inversion for lithologyand fluid predictions, called PCube, where a prior modelfor the elastic properties is defined for different lithologyand fluid classes (LFCs) based on geological knowledgeand/or information from nearby wells. PCube outputsposterior probability for each LFC specified in the priormodel. The inversion results from CSEM and seismic arethen co-interpreted utilizing their complementaryinformation. This offers a direct comparison betweenexpected hydrocarbon-filled reservoirs from seismic andwhether these reservoirs are of high or low saturation fromCSEM inversion results, and to explain resistive anomaliesnot related to hydrocarbons. Applying the workflow onSkrugard datasets, the joint interpretation clearly shows theability to discriminate high hydrocarbon saturated frombrine/low saturated sand reservoirs. Furthermore, theworkflow can also distinguish hydrocarbon related fromnon-hydrocarbon related resistive anomalies.
MDA5 and MAVS Mediate Type I Interferon Responses to Coxsackie B Virus (2009)

Coxsackie B viruses (CVB) are enteroviruses that have been associated with a variety of human diseases, including myocarditis. In the present study, we found that MDA5 and its adaptor molecule MAVS are critical for type I interferon responses to CVB, since the absence of either MAVS or MDA5 leads to deficient type I interferon production and early mortality in mice infected with CVB. Pancreatic and hepatic necrosis were observed on histopathological examination of MAVS and MDA5 knockout mice infected with CVB. Inflammatory cytokine production in response to systemic CVB infection was independent of MAVS. Surprisingly, virus titers were not elevated in MAVS-deficient mice, despite significant reductions in type I interferon levels. These data highlight the importance of type I interferon in host defense and provide insight on the mechanisms of innate immune responses following coxsackievirus infection.
A Study on the Emulsion Polymerization of Methyl Methacrylate (1968)

With the selected emulsifiers for the emulsion polymerization of methyl methacrylate, the HLB of the emulsifier in the reaction system has been studied on the effect of the ratio of tetra sodium-N-(1,2-dicarboxy ethyl)-N-octadecyl sulfosuccinamate(Aerosol 22) to polyethylene glycol nonyl phenyl ether (Noigen EA 160), and also sodium lauryl sulfate(Quolac EX-UB), Disodium-N-octadecyl sulfosuccinamate (Aerosol 18) and Aerosol 22 as emulsifiers having various hydrophilic groups in the molecules have been studied. Results are as follows; 1) The viscosity of the emulsions and the molecular weight of the polymers have maximum values at a constant HLB value of emulsifiers, but their stabilities show minimum point at the value with the titration with the three kinds of mono, bi, tri-valent electrolytes. These results are agreed on the theory of Greth & Wilson in which the properties of polymer emulsions depend upon the HLB system of emulsifiers. 2) The viscosity of the emulsions and the molecular weights of the produced polymers increase more in the case of blending of Aerosol 22 to Noigen EA-160 than of the separate using. 3) The coagulation effects of the divalent electrolytes() are contrast to the effects of monovalent($) and trivalent() in the emulsions with Aerosol 18 or Aerosol 22 which have more than two hydrophilic groups. It seems that the stability of the O/W emulsions by electrolytes is directly related to the parameters of surface physical chemistry such as surface geometry of surface chemical constitution of polymer particles.

Multi-robot teleoperation using direct human hand actions (1996)

This paper presents a novel concept for teleoperation using direct human hand(s) actions which we called 'the hidden robot' concept. The proposed teleoperation scheme is composed of three main components: the operator/ computer loop, the execution loop and between them the bilateral transformation modules linked by the communication channel. Within the operator/computer master loop, the operator performs what we call a 'virtual task', without being constrained by the slave robot. At this stage, the bilateral transformation layer is in charge of extracting, at the low level, pertinent parameters from the virtual task and transforming them onto robot control signals. The execution loop performs control of the slave robot(s) to achieve the desired task, described by the virtual one. At this stage, the transformation layer extracts pertinent data to provide feedback when possible and needed. It also makes sure that the task is being performed correctly in the real site; otherwise, it takes necessary recovery procedures or informs the operator to procede in a different way. We will describe in detail each component, highlighting the originalities of our approach. We will also present the experiment performed by applying this concept to long-distance, simultaneous teleoperation of four slave robots with different kinematics and situated at different locations in France and in Japan. The experimental task consisted of assembling a four-piece puzzle. All the robots had to perform the same task in parallel. We will discuss the experimental results presented in this paper, concering long-distance teleoperated robot control and round-trip communication time delay. The experiment demonstrated the feasibility of the proposed scheme and gave guidelines related to the direct use of the operator hand, within an intermediate representation, as a guide for task execution.
Integrated process management-a case study (1992)

In 1987, International Computers Ltd. (ICL) defined as one of its key strategies for survival 'to become a household name for quality and customer care'. Major worldwide programmes were introduced to develop a new culture into the company whereby every employee would come to regard customer satisfaction as paramount. The author describes how a quality improvement process was implemented across the company and this was subsequently complemented by an integrated process management programme to achieve registration to ISO9001 worldwide.
