An API for high-level software engineering of distributed and mobile applications (2002)

This paper proposes actors as a model for mobile agents. Because of their intrinsic autonomy (thread integration) and behavior changing ability, added to asynchronous communication, actors are naturally mobile entities, and moving actors has no effect on their initial semantics. Then, we propose a standard API on top of Java and RMI, called JavAct, for distributed and mobile applications programming. JavAct is actor-based and allows nearly immediate and strong agent mobility. Mobile actors are localized by means of a forwarding chain technique. Network-level references of actors contribute to location independence of computations. Additionally, in this paper, we give an overview of some related programming systems.
Rol de las proteínas no estructurales en los eventos de replicación del ARN del virus dengue: propuesta de un modelo de replicación del ARN (2003)

Un modelo ilustrativo de los procesos de replicación para el virus dengue y flavivirus en general ha sido diseñado con base a datos experimentales publicados en los últimos diez años. El modelo propone cuatro pasos bien definidos durante el proceso de replicación de ARN: 1) circularización del ARN viral mediada por un stem-loop del extremo 3’ y la región 5’ terminal TR, 2) linearización y síntesis de la forma intermedia replicativa mediada por el complejo NS3-NS5 y la glicoproteína NS1, 3) cambio de estado de NS5 a la forma rígida para la síntesis de formas replicativas y 4)Desensamblaje del sistema de replicación NS3-NS5 mediado por fosforilación y la unión específica de NS5 con un receptor beta de la importina. Este modelo podría ser útil para el planteamiento de nuevos trabajos de investigación destinados al estudio de la replicación en flavivirus.
Minireview: Glucocorticoids in Autoimmunity: Unexpected Targets and Mechanisms (2011)

For decades, natural and synthetic glucocorticoids (GC) have been among the most commonly prescribed classes of immunomodulatory drugs. Their unsurpassed immunosuppressive and antiinflammatory activity along with cost-effectiveness makes these compounds a treatment of choice for the majority of autoimmune and inflammatory diseases, despite serious side effects that frequently accompany GC therapy. The activated GC receptor (GR) that conveys the signaling information of these steroid ligands to the transcriptional machinery engages a number of pathways to ultimately suppress autoimmune responses. Of those, GR-mediated apoptosis of numerous cell types of hematopoietic origin and suppression of proinflammatory cytokine gene expression have been described as the primary mechanisms responsible for the antiinflammatory actions of GC. However, along with the ever-increasing appreciation of the complex functions of the immune system in health and disease, we are beginning to recognize new facets of GR actions in immune cells. Here, we give a brief overview of the extensive literature on the antiinflammatory activities of GC and discuss in greater detail the unexpected pathways, factors, and mechanisms that have recently begun to emerge as novel targets for GC-mediated immunosuppression.

Developing Composite Wood for 3D-Printing (2017)

We present the initial findings of our research project aiming at development of a 3D-printing process for wood composites. The 3D-printing method employed is based on material extrusion principle and utilizes industrial robotics for position and motion control. The unique characteristic of our approach is in the development of the material where we employ exclusively organic components for both the matrix and reinforcement; a decision informed by prioritizing environmental considerations.
Micromagnetics of dual spin-valve GMR heads (1996)

Micromagnetic simulations were performed to study the biasing characteristics and playback performance of actual dual spin-valve GMR heads. Both symmetric and asymmetric dual spin valve heads were analyzed. The study shows that the symmetric dual spin-valve head is not properly biased in its patterned form, without any additional transverse biasing schemes. On the other hand, the asymmetric dual spin valve head is self-biased since in this form, the free layer is free from the demagnetizing fields arising from the pinned layers. However, opposite GMR effects with similar magnitudes would be required for the two spin valve structures in the same multilayer film.
High speed I/O circuit design in multiple voltage domains (2003)

Designing I/O drivers and receivers that must work across multiple voltage domains has several unique circuit-design challenges. One challenge is limitations due to process silicon breakdown voltage. A second disadvantage is the need to transition voltage levels. This is typically done with differential amplifier receivers, special high voltage N or P devices, external pull-ups, or voltage translators. Due to differences in switching levels, matching T/sub CO/ delays though identical receivers in different voltage domains will require additional consideration. Finally, system level simulations of chips crossing multiple voltage domains require 4 terminal devices, non-single global power supply nodes, and must handle multiple process technology files.
The Immunosuppressive Role of Alpha‐Fetoprotein During Pregnancy (1976)

Cell-mediated and humoral immune responses were assessed in mice at mid-term (day 10) in pregnancy. A significant but selective suppression of the primary in vivo antibody (plaque-forming cell) response to SRBC was observed, with the most pronounced effect being on the gammaA response. Similar results were obtained for secondary in vitro antibody synthesis by antigen-primed spleen cells from pregnant mice, demonstrating the intrinsic nature of the inhibition. Pregnant mouse serum (PMS) was shown to suppress primary in vitro antibody synthesis, and the inhibitory effect was abrogated by the selective removal of alpha-fetoprotein (AFP) using affinity chromatography. Normal mouse serum became similarly suppressive in vitro when purified AFP of fetal origin was added to it in concentrations approximating that found in PMS. Spleen cells from pregnant mice showed a suppressed mitogenic response to phytohemagglutinin, a lowered response to concanavalin. A, and a normal response to lipopolysaccharide. In contrast, the allogeneic response of these animals as measured in the one-way mixed lymphocyte culture was enhanced. PMS suppressed both allogeneic and mitogen-induced lymphocyte transformation by spleen cells from nonpregnant mice, and the effect was eliminated by the selective removal of AFP. These findings indicate an important functional role for AFP in normal embryological development.
Cutaneous Acanthamoeba Infection Associated with Leukocytoclastic Vasculitis in an AIDS Patient (1993)

Cutaneous Acanthamoeba infection is a rare complication of immunocompromised individuals including those having acquired immunodeficiency syndrome (AIDS), who often have concurrent central nervous system involvement. Acanthamoeba typically involves the skin and central nervous system by disseminating from a primary focus in the lungs or sinuses. We report an unusual patient with AIDS who developed cutaneous infection with Acanthamoeba, apparently without CNS infection but with sinus involvement. Histologically, the purpuric lesions showed prominent leukocytoclastic vasculitis as well as myriads of organisms.
Absence of γ‐aminobutyric acid‐a receptor potentiation in central hypersomnolence disorders (2016)

Using the Xenopus oocyte assay, we found an absence of GABA-A receptor potentiation with CSF from patients with central hypersomnolence disorders, with no significant differences between hypocretin-deficient and non-hypocretin-deficient patients compared to controls. Ann Neurol 2016;80:259-268.
Population Dynamics of<i>Xanthomonas campestris</i>pv.<i>vesicatoria</i>on Tomato Leaflets Treated with Copper Bactericides (1991)

Populations of copper-resistant (Cu r ) strains of Xanthomonas campestris pv. vesicatoria were monitored in the field on nonsymptomatic tomato leaflets treated with copper or with a copper and mancozeb mixture over three and four seasons, respectively. Copper and a combination of copper and mancozeb reduced epiphytic populations of X. c. vesicatoria, compared to those in the untreated control. Populations of X. c. vesicatoria on leaflets receiving copper and the copper-mancozeb combination differed significantly in only one of three seasons. A positive correlation was observed between epiphytic populations and disease severity (...)
Elevated Serum Haptoglobin is Associated with Clinical Outcome in Triple-Negative Breast Cancer Patients (2012)

Our results indicate that serum levels of Hp may play a role as a potential serum biomarker and prognostic indicator among TNBC patients. Thus, Hp may present a new promising prognostic biomarker in TNBC patients, but independent validations are now necessary for confirmation.
An Empirical Examination of Service Dominant Logic: The Theory of the Network (2007)

Marketing scholars question the ability of the 4Ps to explain higher order phenomena in modern marketing. Scholars contend that marketing's historical framework, based in product centric economic theory, constrains the 4Ps ability to form a foundation for a general theory of marketing. The focus on value embedded in product fails to explain knowledge-based intangible sources of competitive advantage. In response to this concern a new dominant logic for marketing called service-dominant logic (S-D Logic) has been proposed. However, not all scholars are supportive of S-D Logic. Still nescient, S-D Logic lacks a theoretic model, operationalized constructs, and relationships between those constructs. This study addresses those deficiencies by: (1) generation of a grounded theory of a performance-oriented network; (2) empirical assessment of the S-D Logic literature; and (3) development of an inductively generated theory of S-D Logic to include constructs, relationships, outcomes, and hypothesis. This investigation provides an important set of research findings. The resultant service-oriented network theory suggests a theoretic structure for S-D Logic. Use of grounded theory provides a strong empirical foundation based in a leading edge multi-national market segment composed corporations and programs worth hundreds of billions of dollars. The analysis drew upon 44 field interviews and follow-up exchanges. Multiple member checking sessions generated practitioner confirmation of the research conclusions. The work provides actionable theoretical and practical implications. This investigation provides a link between S-D Logic as a foundation for a general theory of marketing and initial model of suggestive of such theory. For the practitioner the service-oriented network model provides actionable constructs. The antecedents identified are largely influencable by inter-firm leadership and provides them a mechanism to tailor the specific service-oriented strategy to support the desired network value propositions.
Characterization of the exposed carbohydrates on the surface membrane of adult<i>Schistosoma mansoni</i>by analysis of lectin binding (1980)

The surface architecture of adult male Schistosoma mansoni was explored using a range of lectins with differing carbohydrate specificites. Highest specific binding was achieved with concanavalin A and the agglutinin of molecular weight 60000 from Ricinus communis; the binding of wheat germ agglutinin was mostly non-specific. Small amounts of peanut agglutinin and soybean agglutinin binding were observed and the binding of these lectins was increased by pre-treating the parasite with neuraminidase. The fucose binding protein of Lotus tetragonolobus failed to bind. These results indicate that mannose and/or glucose, galactose, N-acetylglucosamine, N-acetyl-galactosamine and sialic acid are exposed on the surface of the adult male schistosome.
Could Myocarditis, Insulin-Dependent Diabetes Mellitus, and Guillain-Barré Syndrome Be Caused by One or More Infectious Agents Carried by Rodents? (1998)

The numbers of small rodents in northern Sweden fluctuate heavily, peaking every 3 or 4 years. We found that the incidence of Guillain-Barré syndrome and insulin-dependent diabetes mellitus, as well as the number of deaths caused by myocarditis, followed the fluctuations in numbers of bank voles, although with different time lags. An environmental factor, such as an infectious agent, has been suggested for all three diseases. We hypothesize that Guillain-Barré syndrome, myocarditis, and insulin-dependent diabetes mellitus in humans in Sweden are caused by one or more infectious agents carried by small rodents. Also, a group of novel picornaviruses recently isolated from these small rodents is being investigated as the possible etiologic agent(s).
Monte Carlo Simulation Based Price Zone Partitioning Considering Market Uncertainty (2006)

The key for establishing simple and efficient zonal pricing scheme is to accurately partition transmission network in the presence of congestion. Unfortunately, in actual power market operation, operators usually establish price zones based on their experiences without mathematical analysis. In order to achieve accurate price zone partition, this paper proposes a Monte Carlo simulation based price zone partitioning method under market uncertainty. In this method, the lines that are most likely to get congested are determined first through a probability analysis while taking into account the market uncertainties in the generation bids, loads and bilateral transactions. Secondly the sensitivities of nodal power injections to the power flows on all congested lines are extracted as features of the nodal price, forming the cluster samples. Then a fuzzy c-means clustering algorithm for price zone partition is proposed by which the accurate and rational price zone partitioning is realized. Finally, taking IEEE 118-node system for example, the effectiveness and feasibility of this proposed method are verified
Application of Kalman Filters for the Fault Diagnoses of Aircraft Engine (2010)

In this paper, aircraft engine sensor fault diagnostics based on the estimation of health degradation was investigated. The tracking filter estimates engine health condition over the course of engine's life. Through this integration, the on-line fault detection algorithm is able to maintain its diagnostic effectiveness as the aircraft engine degrades over its lifetime. The integrated approach was investigated in a simulation environment using a nonlinear engine model. The evaluation result showed that this approach is essential to maintain online fault detection capability in the presence of health degradation. In this paper, an approach has been proposed to detect and isolate the aircraft sensor and actuator failures occurred in the aircraft control system. A bank of Kalman filters were used to detect and isolate sensor failures, each of Kalman filter is designed based on a specific hypothesis for detecting a specific sensor fault. In the event that a fault does occur, all filters except the one using the correct hypothesis will produce large estimation errors, from which a specific fault is isolated. Failures in the sensors and actuators affect the characteristics of the residual signals of the Kalman filter. When the Kalman filter is used, the decision statistics changes regardless the faults in the sensor or in the actuator. While a Robust Kalman filter is used, it is easy to distinguish the sensor and actuator fault.

A fast and effective method for motion estimation (2005)

Today, the market for multimedia devices (such as DV camcoders, digital still cameras and videophones) is growing dramatically. Most of these multimedia video data have to be compressed for storage or transmission by international standards such as MPEG and H.26x series. In these standards, motion estimation is the most time consuming step. This study proposes a new approach to reduce the search time of motion estimation in modern video compression. The proposed method applies the spider-web pattern inside the search area to get the performance gain. The simulation results show that our algorithm has better efficiency than previous works and has minimal impact on PSNR.
Electromigration and failure in electronics: An introduction (1971)

Some fundamental aspects of electromigration phenomena as they have been studied in "bulk" metallic conductors are reviewed. In an electric field atoms are subjected to a force due to the field, and to a force which results from the motion of electrical carriers, electrons, or holes. In bulk samples, and at high temperatures, these forces cause the displacement of atoms by a lattice mechanism which is also responsible for the diffusion of atoms in a concentration gradient. In thin films, electromigration has been found to occur at lower temperatures (and higher current densities) by a grain boundary diffusion mechanism. Electromigration may cause failures at material discontinuities, such as found at terminals, at temperature gradients, or at structural inhomogeneities. The process of crack formation, as observed in aluminum thin films, is described. Failure times are a function of the activation energy for diffusion and of exponents of the current density which vary for different failure modes. The effects of film purity, orientation, grain size, glass overcoat, and solute additions on lifetime are reviewed. Practical guidelines for the design of thin-film interconnections, and for the interpretation of accelerated test data are given.
Efficient Dense 3D Rigid-Body Motion Segmentation in RGB-D Video (2013)

Motion is a fundamental segmentation cue in video.Many current approaches segment 3D motion in monocular or stereo image sequences, mostly relying on sparse interest points or being dense but computationally demanding.We propose an efficient expectation-maximization (EM) framework for dense 3D segmentation of moving rigid parts in RGB-D video.Our approach segments two images into pixel regions that undergo coherent 3D rigid-body motion.Our formulation treats background and foreground objects equally and poses no further assumptions on the motion of the camera or the objects than rigidness.While our EM-formulation is not restricted to a specific image representation, we supplement it with efficient image representation and registration for rapid segmentation of RGB-D video.In experiments we demonstrate that our approach recovers segmentation and 3D motion at good precision.
IN-SITU Diagnostics For Deposition And Processing Of High T c Superconducting Thin Films (1990)

The deposition of high quality superconducting thin films based on the metal oxides has given rise to a variety of needs for diagnostic techniques. These needs are primarily for monitoring, 1. the material ejection process from the target, 2. the ejected vapor interaction with the background oxygen, 3. the crystallization dynamics at the substrate and 4. post deposition analysis and processing of the film. This paper summarizes some of the recent work in this direction
COMPARISONS OF PAIN RELIEF MECHANISMS BETWEEN NEEDLING TO THE MUSCLE, STATIC MAGNETIC FIELD, EXTERNAL QIGONG AND NEEDLING TO THE ACUPUNCTURE POINT (1996)

Pain relief mechanisms of needling to the pain-producing muscle, application of a static magnetic field or external qigong, and needling to the acupuncture point were investigated in an experimentally designed pain producing muscle of animals. Single isometric twitch height in situ was reduced gradually by 10 Hz tetanic stimulation for one hour of the gastrocnemius muscle of guinea pigs. This reduction of twitch height was recovered by injection of 0.3-1 ml saline to the artery of this muscle, or of injection of a vasodilator, isoproterenol dissolved in 0.1 ml saline. Hence, reduction of twitch height could be induced by reduction of circulation in the muscle and recovery of it could be induced be recovery of circulation. Since it is easily considered that a pain substance might be accumulated in a muscle under reduced circulation, and such an accumulated substance might be eliminated by recovery of circulation, the reduction of twitch height after tetanic stimulation could be estimated as the pain-producing muscle and recovery of twitch, as the pain relieving muscle. 1) Needling to the pain muscle, 2) application of a static magnetic field or external qigong to the muscle, and 3) needling to the acupuncture point recovered the reduced twitch height due to tetanic stimulation. Atropine abolished this effect induced by the above 1, 2 and 3 procedures. Hence, the cholinergic vasodilator nerve might be involved in the induction of this effect. A sciatic nerve cut did not influence the effect of 1), but abolished the effect of 3). Denervation and capsaicin abolished the effect of 1). Substance P and a calcitonin gene- related peptide (CGRP) recovered the reduced twitch height, and atropine blocked the effect of CGRP, but did not block that of substance P. The effect of 2) was equivalent to that of anticholinesterase. A rostral lesion of the contralateral anterior hypothalamus did not abolish the effect of 3, but a caudal lesion of this region did. Electrical stimulation of this region produced an effect similar to that of 3). From these results, it was concluded that muscle pain relief by these procedures might be induced by recovery of circulation due to the enhanced release of acetylcholine as a result of activation of the cholinergic vasodilator nerve endings innervated to the muscle artery. However, manners of activation of the cholinergic nerve was different in effects of 1), 2) and 3). 1) might be induced by axon reflex of the CGRP nerve, 2) might be induced by inhibition of cholinesterase and 3) might be induced by a somato-autonomic reflex. The reflex center of this might be in the anterior hypothalamus.
Permanent Cardiac Pacing with Sutureless Myocardial Electrodes: Experience in First One Hundred Patients (1980)

This report concerns our experience with a sutureless myocardial lead which we have used in 103 patients for establishment of permanent cardiac pacing. The electrode was inserted through a subxiphoid approach in all patients. Results to date indicate that this technique compares favorably with the presently popular transvenous technique as far as immediate or long-term morbidity is concerned. Complications were related entirely to pericardiotomy; no lead failure was seen during a maximum follow-up period of four years.
