Maximizing uniaxial tensile strain in large-area silicon-on-insulator islands on compliant substrates (2006)

Recently we have demonstrated a process for generating uniaxial tensile strain in silicon. In this work, we generate uniaxially strained silicon and anisotropically strained silicon germanium on insulator with strain in both ⟨100⟩ and ⟨110⟩ in-plane directions. The strain is uniform over fairly large areas, and relaxed silicon-germanium alloy buffers are not used. The magnitude of uniaxial strain generated by the process is very dependent on the in-plane crystal direction, and can be modeled accurately using the known mechanical properties of silicon and germanium. A maximum uniaxial silicon strain of 1.0% in the ⟨100⟩ direction is achieved. Numerical simulations of the dynamic strain generation process are used to identify process windows for achieving maximum uniaxial silicon strain for different structural geometries.
Cellular stress conditions are reflected in the protein and RNA content of endothelial cell‐derived exosomes (2012)

Our data show that hypoxia and endothelial activation are reflected in RNA and protein exosome composition, and that exposure to high sugar concentrations alters exosome protein composition only to a minor extend, and does not affect exosome RNA composition.

Isolation and characterization of the CNBr peptides from the proteolytically derived <i>N</i>-terminal fragment of ovine opsin (1983)

Ovine rhodopsin may be cleaved in situ by Staphylococcus aureus V8 proteinase into two membrane-bound fragments designated V8-L (27 000 mol.wt.) and V8-S (12 000 mol.wt.). After purification of the proteolysed complex by affinity chromatography in detergent using concanavalin A immobilized on Sepharose 4B, the two polypeptide fragments may be separated by gel-permeation chromatography on Sephadex LH-60. Digestion of the N-terminal-derived V8-L fragment with CNBr in 70% (v/v) trifluoroacetic acid resulted in a peptide mixture that could be fractionated by procedures involving gel-permeation chromatography in organic and aqueous solvents and the use of differential solubility. The complete or partial sequences of all ten peptides are reported.
A potential peptide vaccine against two different strains of influenza virus isolated at intervals of about 10 years. (1994)

We have developed a strategy for making synthetic peptide vaccines, in which a peptide, HA127-133, derived from the hemagglutinin (HA) of A/Aichi/2/68(H3N2) influenza virus (Aichi/68) is introduced into the Ab binding component consisting of 43-46 and 54-58 residues of a pigeon cytochrome c analogue peptide, 46F50V54A. Indeed, this hybrid peptide, 46F/HA127-133/54A, induced impressive T-cell responses and antibody production neutralizing infectivity of Aichi/68 in vitro. In a subsequent study we found that 46F/HA127-133/54A(18mer) peptide antigen, which had been prepared by substitution at the central five residues of 46F50V54A with HA127-133, generated T-cell responses and neutralizing antibody responses as well. On the basis of these prior findings, in the present study we analyzed immunopotency of 46F/HA127-133/54A(18mer) in vivo administered in several ways to I-Ab mice. We show herein that this peptide vaccine loaded in multilamellar liposomes without adjuvant protects the mice against infection with Aichi/68 within 2 weeks after final immunization. Further, this peptide vaccine was shown to be effective in preventing infection with a naturally occurring antigenic variant, A/Texas/1/77(H3N2), carrying the same sequence at 127-133 of the HA as Aichi/68 virus. Since this part of the HA is relatively conserved among H3 subtype influenza viruses, our peptide vaccine may become the basis for a new strategy to prepare effective vaccines that will overcome the ineffectiveness of classical vaccines attributable to antigenic drift of influenza viruses.
Simultaneous Localization and Mapping Using Rao-Blackwellized Particle Filters in Multi Robot Systems (2010)

In this paper we investigate the problem of Simultaneous Localization and Mapping (SLAM) for a multi robot system. Relaxing some assumptions that characterize related work we propose an application of Rao-Blackwellized Particle Filters (RBPF) for the purpose of cooperatively estimating SLAM posterior. We consider a realistic setup in which the robots start from unknown initial poses (relative locations are unknown too), and travel in the environment in order to build a shared representation of the latter. The robots are required to exchange a small amount of information only when a rendezvous event occurs and to measure relative poses during the meeting. As a consequence the approach also applies when using an unreliable wireless channel or short range communication technologies (bluetooth, RFId, etc.). Moreover it allows to take into account the uncertainty in relative pose measurements. The proposed technique, which constitutes a distributed solution to the multi robot SLAM problem, is further validated through simulations and experimental tests.
The encapsulation of pancreatic islets. Investigation of insulin secretion and content in vitro. (1985)

Polyelectrolyte complex capsules from cellulose sulphate can be formed by precipitation in a polycation bath. The application of this new method for encapsulation of pancreatic islets requires investigations whether and to what extent cellulose sulphate injures viability and functionality of the pancreatic islets. Islets cultures in the presence of 2% cellulose sulphate for up to 3 weeks are characterized by unchanged insulin content, secretion and biosynthesis when compared to appropriate controls.
Detailed experiments on helium-neon FM lasers (1965)

Results are reported on the detailed measurements of the operating characteristics of an He-Ne FM laser oscillating at 6328Å. Experiments were performed in both the "phase-locked" and the "FM" regions of operation, with particular emphasis on the FM region. In the phase-locked region, the pulsed output of the FM laser was observed and studied. In the FM region, measurements were made to study the laser power output, modulation index, and distortion (deviation from an ideal FM signal) as functions of the amplitude and frequency of the applied phase perturbation. Most of these experiments were performed under conditions of low laser excess gain (relatively few modes above threshold for the free-running laser); however, the results are useful for predicting the behavior of FM laser operation with larger excess gain. In addition to describing the practical operation of an FM laser, these experiments provide a check on the applicability of the FM laser theory of Harris and McDuff. An exact quantitative comparison between theory and experiment was not attempted, but the qualitative agreement is very good.
Lymphocyte transformation and interferon production in human mononuclear cell microcultures for assay of cellular immunity to herpes simplex virus (1976)

Interferon production and transformation in response to herpes simplex virus antigen were studied in microcultures of human mononuclear cells. Mononuclear cells consisting of monocytes and both T and B lymphocytes were purified by Ficoll-Hypaque gradients. Lymphocytes, predominantly T with 5% B, were obtained by passage of buffy-coat cells through nylon fiber columns. For some experiments, autochthonous macrophages and column-purified lymphocytes were stimulated with herpesvirus antigen. The effect of specific antibody and cell concentration on reactivity is described. Crude and purified antigens were compared as cell culture stimulants. Significant differences in transformation and interferon were observed between donors with a history of herpes labialis and donors with no detectable antibody, both in cultures prepared by Ficoll-Hypaque gradients and by column purification of lymphocytes. Cultures from seronegative donors prepared by Ficoll-Hypaque gradients produced interferon but did not transform when stimulated by herpes simplex antigen. "Immune" interferon production, that is, type II as opposed to type I, occurred only with autochthonous macrophage and column-purified lymphocyte cultures. Interferon produced by Ficoll-Hypaque-purified mononuclear cultures was type I, and its production was unrelated to immune status. Similarly, column-purified lymphocytes responded to herpes simplex virus antigen with type I interferon if obtained from a seropositive donor.
Analysis of (r,q) Perishable Inventory System Using the Ttwo-Phase Method (1999)

This study presents a two-phase method to analyze (r,Q) perishable inventory system with last in first out (LIFO) issuing discipline, periodic review, finite product lifetime, constant lead time, and stochastic demand. The two-phase method utilized in this research comprises of the review phase and the demand phase. The deterministic portion of the above-mentioned complex perishable inventory system, including ordering policy and decision, constant order lead time, replenishment, and spoilage, is considered in the review phase. The stochastic portion of this system, including probabilistic demand distribution and LIFO issuing discipline, is carefully examined in the demand phase. Age distribution vector is introduced in this study to represent on-hand inventory levels in terms of their ages. In the demand phase, the age distribution vectors are defined as states, they being identified and validated according to the (r,Q) policy, constant lead time, and LIFO issuing discipline. The two-phase methodology enables one to apply the Markov decision processes to the demand phase and to be able to resolve the complex (r,Q) perishable inventory system with periodic review, finite product lifetime, constant lead time, stochastic customer demand, and LIFO customer issuing behavior.
Properties of polytetrafluoroethylene (PTFE) paste extrudates (2002)

Abstract In this work, we have studied the effects of extrusion die design, resin molecular structure, and lubricant concentration on the properties of PTFE paste extrudates by performing macroscopic extrusion pressure measurements, Raman spectroscopy, differential scanning calorimetry and mechanical testing on the extrudates. Five resins of different molecular structures were tested. We have found that a balance between fibril quantity and quality (in terms of fibril orientation and continuousness) is necessary to ensure acceptable products, as illustrated through the effects of the operating variables on the extrudate tensile strength. The number of fibrils formed during extrusion can be increased by extruding the paste through a die of larger reduction ratio or by decreasing the lubricant content in the paste, thereby increasing the extrusion pressure. However, excessive pressure will cause fibril breakage. By using a die of larger entrance angle, the extent of fibrillation is also increased, although the quality of the fibrils is somewhat compromised. Increasing the die aspect ( L / D ) ratio does not increase the extent of fibrillation. However, it increases the degree of fibril orientation and ensures smoother extrudate. Finally, we have found that extrudates obtained using a paste of higher molecular weight are mechanically superior.
IBM System z9 Open Systems Adapter for Communication Controller for Linux (2007)

The IBM 374× Communication Controllers, and the NCP (network control program) software that runs on them, have been at the center of the IBM SNA (Systems Network Architecture) for many years. However, the 374× hardware is no longer being produced. In order to continue to offer IBM customers various functions provided by the NCP product, IBM has developed a Communication Controller for Linux® (CCL) for the IBM System z™. CCL is a software program that emulates the 374x hardware, enabling the NCP to function in Linux. IBM customers now have the ability to migrate their NCP product to a Linux partition on System z. The current NCP product, running on an IBM 374x Communication Controller, supports both host channel and network attachment. The channel protocol used for the host-channel support is referred to as channel data link control (CDLC). In order to provide the System z9™ host operating systems with the ability to attach to the new CCL NCP over a channel interface, a new channel adapter is required. The new innovative Open Systems Adapter for NCP (OSN) channel support provided by the OSA-Express2 allows various operating systems on the same System z9 to attach “internally” to the CCL without using any external network or channel fabric.
Identification and cDNA Cloning of Alveolin, an Extracellular Metalloproteinase, Which Induces Chorion Hardening of Medaka (Oryzias latipes) Eggs upon Fertilization (2000)

Chorion hardening is triggered by the contents of cortical alveoli that are released upon fertilization of medaka (<i>Oryzias latipes</i>) eggs. We purified the chorion hardening-inducing activity as a single protein from the exudate of cortical alveoli of medaka eggs. This activity was co-purified with proteolytic activity of the chorion protein ZI-1,2. Based on the amino acid sequence of purified protein, we cloned the cDNA of this protein from a medaka ovarian cDNA library. Sequence analyses revealed typical sequence features, a zinc-binding motif and a methionine turn motif, of the astacin metalloproteinase family. We termed this protein "alveolin." Alveolin has a molecular mass of 21.5 kDa deduced by the amino acid sequence and neutral optimal pH range. Alveolin hydrolyzes ZI-1,2. Alveolin activity was strongly inhibited by metal-chelating agents but not by various proteinase inhibitors. To our knowledge, this is the first description of the isolation and identification of the chorion hardening-inducing factor from cortical alveoli exudate of teleost eggs.

Interfacial Scattering at Electrochemically Fabricated Atom-Scale Junctions between Thin Gold Film Electrodes in a Microfluidic Channel (2004)

Atom-scale junctions were formed between two Au thin-film electrodes by a combination of lithography, microfluidics, and electrochemistry. Two Au thin-film electrodes with a small (0.25-25 microm) gap between them were lithographically defined such that the gap fell in the center of a 100-microm-wide microfluidic channel in poly(dimethylsiloxane). Directional electrodeposition between the Au thin-film electrodes, accomplished by applying a potential between the thin-film electrodes, caused Au to etch from the anode and deposit on the cathode, thereby closing the gap. Current through the gap was monitored continuously, and the directional electrodeposition was terminated when a current near that corresponding to the conductance quantum, G(0) = 2e(2)/h, was reached. To regenerate the device, the atom-scale junction was broken with a potential sweep, the microfluidic channel was rinsed, and the junction was re-formed with a subsequent comparator-terminated directional electrodeposition. Alternating current impedance was measured while hexadecanethiol (HDT) was chemisorbed onto the atom-scale junction. The interfacial scattering from chemisorption of the Lewis base HDT on the atom-scale junction caused a normalized impedance change of 71 +/- 1%, the noise level being equivalent to a population fluctuation of five HDT molecules.
La externalización de la función de compras (2005)

Los procesos de externalizacion en las empresas son una practica constante desde el momento en que se encuentra en el mercado otra empresa que realiza el servicio o suministra el producto que se necesita en unas condiciones y precios mas competitivos que los obtenidos por la empresa contratante. En la actualidad los procesos de externalizacion de compras parecen imponerse. El presente trabajo recoge, inicialmente, una serie de aspectos a tener en cuenta para llevar a cabo cualquier externalizacion, centrandose, posteriormente, en el proceso de externalizacion de compras o “procurement outsourcing”. Se abordan aspectos terminologicos, puntos a tener en cuenta para aplicar estos procesos, tendencia en la practica de los mismos por parte de las empresas, servicios mas habituales ofrecidos por los PSP (Proveedores de servicios externos) y reflexiones a tener en cuenta para tomar la decision de externalizar las compras.

Optimization of shovel-truck system for surface mining (2009)

In surface mining operations, truck haulage is the largest item in the operating costs, constituting 50 to 60% of the total. In order to reduce this cost, it is necessary to allocate and dispatch the trucks efficiently. This paper describes shovel and truck operation models and optimization approaches for the allocation and dispatching of trucks under various operating conditions. Closed queuing network theory is employed for the allocation of trucks and linear programming for the purpose of truck dispatching to shovels. A case study was applied for the Orhaneli Open Pit Coal Mine in Turkey. This approach would provide the capability of estimating system performance measures (mine throughput, mean number of trucks, mean waiting time, etc.) for planning purposes when the truck fleet is composed of identical trucks. A computational study is presented to show how choosing the optimum number of trucks and optimum dispatching policy affect the cost of moving material in a truckshovel system.
Sparse Contextual Activation for Efficient Visual Re-Ranking (2016)

In this paper, we propose an extremely efficient algorithm for visual re-ranking. By considering the original pairwise distance in the contextual space, we develop a feature vector called sparse contextual activation (SCA) that encodes the local distribution of an image. Hence, re-ranking task can be simply accomplished by vector comparison under the generalized Jaccard metric, which has its theoretical meaning in the fuzzy set theory. In order to improve the time efficiency of re-ranking procedure, inverted index is successfully introduced to speed up the computation of generalized Jaccard metric. As a result, the average time cost of re-ranking for a certain query can be controlled within 1 ms. Furthermore, inspired by query expansion, we also develop an additional method called local consistency enhancement on the proposed SCA to improve the retrieval performance in an unsupervised manner. On the other hand, the retrieval performance using a single feature may not be satisfactory enough, which inspires us to fuse multiple complementary features for accurate retrieval. Based on SCA, a robust feature fusion algorithm is exploited that also preserves the characteristic of high time efficiency. We assess our proposed method in various visual re-ranking tasks. Experimental results on Princeton shape benchmark (3D object), WM-SRHEC07 (3D competition), YAEL data set B (face), MPEG-7 data set (shape), and Ukbench data set (image) manifest the effectiveness and efficiency of SCA.
