<title>Demonstration of a repetitively pulsed magnetically gain-switched chemical oxygen iodine laser</title> (1993)

Recently, modulation of the output from a chemical oxygen iodine laser (COIL) has been demonstrated by applying a pulsed magnetic field directly to the laser cavity. A peak-to- average power enhancement of 3.2 was obtained. The rate of change of the magnetic field in these experiments, however, was relatively slow, 0.5 gauss/microsecond(s) . In this article, we report the demonstration of a fast field switching technique (325 gauss/microsecond(s) ), in which switching occurs faster than the laser mode can build up. With this technique, we have achieved a peak- to-average power enhancement of 12.7 and achieved true gain-switched operation.
Priority-based Fair Scheduling in Edge Computing (2020)

Scheduling is important in Edge computing. In contrast to the Cloud, Edge resources are hardware limited and cannot support workload-driven infrastructure scaling. Hence, resource allocation and scheduling for the Edge requires a fresh perspective. Existing Edge scheduling research assumes availability of all needed resources whenever a job request is made. This paper challenges that assumption, since not all job requests from a Cloud server can be scheduled on an Edge node. Thus, guaranteeing fairness among the clients (Cloud servers offloading jobs) while accounting for priorities of the jobs becomes a critical task. This paper presents four scheduling techniques, the first is a naive first come first serve strategy and further proposes three strategies, namely a client fair, priority fair, and hybrid that accounts for the fairness of both clients and job priorities. An evaluation on a target platform under three different scenarios, namely equal, random, and Gaussian job distributions is presented. The experimental studies highlight the low overheads and the distribution of scheduled jobs on the Edge node when compared to the naive strategy. The results confirm the superior performance of the hybrid strategy and showcase the feasibility of fair schedulers for Edge computing.
A method to develop common management service in many management application programs based on management service specification using GDMO template (2002)

In the OSI (open systems interconnection) management system, many kinds of management application programs are developed in order to manage the communication networks. Therefore, it is necessary to develop applications efficiently. One of methods which develop applications efficiently is that the management system provides common functions to each application as a management service. We propose one method that develops the above management service. We define the management service as a function object. The management system executes the management service based on the management service specifications defined in the GDMO (Guidelines for the Definition of Managed Object) templates.
Thread cooperation in multicore architectures for frequency counting over multiple data streams (2009)

Many real-world data stream analysis applications such as network monitoring, click stream analysis , and others require combining multiple streams of data arriving from multiple sources. This is referred to as multi-stream analysis . To deal with high stream arrival rates, it is desirable that such systems be capable of supporting very high processing throughput. The advent of multicore processors and powerful servers driven by these processors calls for efficient parallel designs that can effectively utilize the parallelism of the multicores, since performance improvement is possible only through effective parallelism. In this paper, we address the problem of parallelizing multi-stream analysis in the context of multicore processors. Specifically, we concentrate on parallelizing frequent elements, top- k , and frequency counting over multiple streams. We discuss the challenges in designing an efficient parallel system for multi-stream processing. Our evaluation and analysis reveals that traditional "contention" based locking results in excessive overhead and wait, which in turn leads to severe performance degradation in modern multicore architectures. Based on our analysis, we propose a "cooperation" based locking paradigm for efficient parallelization of frequency counting. The proposed "cooperation" based paradigm removes waits associated with synchronization, and allows replacing locks by much cheaper atomic synchronization primitives. Our implementation of the proposed paradigm to parallelize a well known frequency counting algorithm shows the benefits of the proposed "cooperation" based locking paradigm when compared to the traditional "contention" based locking paradigm. In our experiments, the proposed "cooperation" based design outperforms the traditional "contention" based design by a factor of 2--5.5X for synthetic zipfian data sets.

The good results and absence of side effects in patients treated with interferon + N-acetyl cysteine recommend wider use of this association.
Long-term control of arterial blood pressure (1992)

Two concepts for the long-term regulation of arterial pressure were considered in this review, the neural control hypothesis and the volume regulation hypothesis. The role of the nervous system and fluid volume regulation are intertwined in a way that has made it difficult to experimentally evaluate their separate contributions in the long-term regulation of arterial pressure. Nevertheless, from a substantial body of work related to the neural control of cardiovascular function, it appears that the ability of the nervous system to control arterial pressure is limited to the detection and correction of rapid short-term changes of arterial pressure. A long and exhaustive search has yet yielded no new neural mechanisms beyond the classic sinoaortic baroreceptors that can detect changes of arterial pressure. The baroreceptor mechanisms are of great importance for the moment-to-moment stabilization of arterial pressure, but because they do not possess sufficient strength and because they reset in time to the prevailing level of arterial pressure, they cannot provide a sustained negative feedback signal to provide long-term regulation of arterial pressure in face of sustained stimuli. This is not to say that the nervous system cannot affect the long-term level of arterial pressure. A distinction is made here between the many factors that can influence the long-term level of pressure and those that actually serve to detect changes of pressure and serve to maintain the level of pressure within a narrow range over the period of our adult lifetime. In this sense, there is evidence that in genetically susceptible individuals, environmental stresses can influence the long-term level of arterial pressure via the central and peripheral neural autonomic pathways. It is inappropriate, however, to view the nervous system as a long-term controller of arterial pressure because there is yet no evidence that the CNS can detect changes of arterial pressure nor changes in total body sodium and water content over sustained periods whereby it could provide an adequate long-term normalization of such error signals. In contrast, evidence has grown in support of the renal pressure-diuresis volume regulation hypothesis for the long-term control of arterial pressure over the past decade. An enhanced understanding of the mechanisms of pressure diuresis-natriuresis coupled with studies exploring how changes of vascular volume can influence vascular smooth muscle tone provide a compelling basis for this hypothesis of long-term arterial pressure regulation. This overall concept is represented and summarized in Figure 12.(ABSTRACT TRUNCATED AT 400 WORDS)
Continuous production of California timber can yield profitable returns (1947)

Two types of landowner are affected by the emerging and increasing opportunities for the management of timber on a continuous basis as a permanent and profitable business—the industrial lumbermen and the farmer or other rural proprietor of a small tract of woodland.
Coagulation under Flow: The Influence of Flow-Mediated Transport on the Initiation and Inhibition of Coagulation (2005)

A mathematical model of intravascular coagulation is presented; it encompasses the biochemistry of the tissue factor pathway, platelet activation and deposition on the subendothelium, and flow- and diffusion-mediated transport of coagulation proteins and platelets. Simulation experiments carried out with the model indicate the predominant role played by the physical processes of platelet deposition and flow-mediated removal of enzymes in inhibiting coagulation in the vicinity of vascular injury. Sufficiently rapid production of factors IXa and Xa by the TF:VIIa complex can overcome this inhibition and lead to formation of significant amounts of the tenase complex on the surface of activated platelets and, as a consequence, to substantial thrombin production. Chemical inhibitors are seen to play almost no (TFPI) or little (AT-III and APC) role in determining whether substantial thrombin production will occur. The role of APC is limited by the necessity for diffusion of thrombin from the site of injury to nearby endothelial cells to form the thrombomodulin-thrombin complex and for diffusion in the reverse direction of the APC made by this complex. TFPI plays an insignificant part in inhibiting the TF:VIIa complex under the conditions studied whether its action involves sequential binding of TFPI to Xa and then TFPI:Xa to TF:VIIa, or direct binding of TFPI to Xa already bound to the TF:VIIa complex.
Trends in the Interaction of the Strong Acids HCl, HBr, and HI with a Photoluminescing Porous Silicon Surface (1997)

The influence of the strong acids HCl, HBr, and HI on the nitrogen laser-excited photoluminescence (PL) from a porous silicon (PS) surface is established. In contrast to the stabilizing effect of hydrochloric acid on a PS surface photoluminescing in doubly deionized water, HI almost completely quenches the photoluminescence. The effect of an HBr solution is intermediate. These observations focus attention on (1) the importance of ambient oxygen in the region of a photoluminescing sample and (2) the likelihood that the PS photoluminescence results exclusively from a surface bound triplet exciton with little contribution from low-lying singlet states.

Combining memory and a controller with photonics through 3D-stacking to enable scalable and energy-efficient systems (2011)

It is well-known that memory latency, energy, capacity, bandwidth, and scalability will be critical bottlenecks in future large-scale systems. This paper addresses these problems, focusing on the interface between the compute cores and memory, comprising the physical interconnect and the memory access protocol. For the physical interconnect, we study the prudent use of emerging silicon-photonic technology to reduce energy consumption and improve capacity scaling. We conclude that photonics are effective primarily to improve socket-edge bandwidth by breaking the pin barrier, and for use on heavily utilized links. For the access protocol, we propose a novel packet based interface that relinquishes most of the tight control that the memory controller holds in current systems and allows the memory modules to be more autonomous, improving flexibility and interoperability. The key enabler here is the introduction of a 3D-stacked interface die that allows both these optimizations without modifying commodity memory dies . The interface die handles all conversion between optics and electronics, as well as all low-level memory device control functionality. Communication beyond the interface die is fully electrical, with TSVs between dies and low-swing wires on-die. We show that such an approach results in substantially lowered energy consumption, reduced latency, better scalability to large capacities, and better support for heterogeneity and interoperability.
A novel signature verification and authentication system using image transformations and Artificial Neural Network (2013)

This paper proposes an Artificial Neural Network based approach for implementing Automatic Signature verification and authentication system. In this era, with the rapid growth of Internet and the necessity of localized verification systems, handwritten signature has become an important biometric feature for the purpose of verification and authentication. The proposed method comprises spatial and frequency domain techniques for transformation. After extracting the Region of Interest Ripplet-II Transformation, Fractal Dimension and Log Polar Transformation are carried out to extract descriptors of the concerned signature to be verified as well as authenticated. In decision making stage Feed Forward Back Propagation Neural Network is used for verification and authentication purpose. This system has been tested with large sample of signatures to show its verification accuracy and the results have been found around 96.15%. Also forgery detection rate has been found 92% which is very encouraging. False Acceptance Rate and False Rejection rate of our system has been determined 5.28% and 2.56% respectively. This approach has been compared with some existing system and it has been observed that this system shows better performance.

It seems that the use of chitosan nanoparticles has no significant effect on the protective immunization of the mice against botulinum BoNT/E in either route (<i>P></i>0.05), even intranasal administration of the bare antigen gives better mice immunization against the toxin.
Inosine analogs as chemotherapeutic agents for African trypanosomes: metabolism in trypanosomes and efficacy in tissue culture (1985)

Certain purine analogs, the pyrazolopyrimidines, are effective chemotherapeutic agents against Leishmania spp. and Trypanosoma cruzi both in vitro and in some clinical models. Heretofore they have not been effective against the African trypanosomes; this suggested that these organisms were not comparable to the other pathogens with respect to their purine metabolism. We have studied the efficacy and metabolism of the pyrazolopyrimidine bases allopurinol and thiopurinol, their respective ribonucleosides, and the C-nucleosides formycin B and 9-deazainosine in Trypanosoma brucei subsp. gambiense and Trypanosoma brucei subsp. rhodesiense. The efficacy of these compounds was dependent on the purine content of the culture medium. The C-nucleosides were the most effective, with 90% effective doses for formycin B and 9-deazainosine of 0.01 and 2 micrograms/ml, respectively. Metabolism was the same in both the bloodstream and culture forms and identical to that reported for Leishmania spp. and T. cruzi. Both agents were phosphorylated to the ribonucleotide and then aminated to produce adenine nucleotide analogs. Growth inhibition studies were performed with three inosine analogs (allopurinol riboside, formycin B, and 9-deazainosine) on trypomastigotes grown in bone marrow tissue culture. Both C-nucleosides eradicated the infection at a concentration of 0.25 micrograms/ml. Unlike formycin B, 9-deazainosine is not known to be aminated by mammalian cells and appears to be relatively nontoxic in three different mammalian tissue culture systems. This nucleoside was very active against all pathogenic leishmaniae and trypanosomes investigated and is worthy of further study.
Effect of pH on the nuclear magnetic resonance relaxivity of encapsulated solid paramagnetic substances. (1989)

Encapsulation, by acid-stable materials, of solid paramagnetic metal complexes based on sulphonated polystyrene ion-exchange resin, prevents the significant demetallation which otherwise occurs when the complexes are subjected to an acidic environment equivalent to that of the human stomach (pH 1-2). In turn, this protects the ability of those complexes to enhance the nuclear magnetic resonance (NMR) spin-lattice relaxation rate of water. Application of the results in the development of contrast agents for MR imaging of the gastrointestinal (GI) tract, in the evaluation of coatings used in drug formulations, and in the measurement of GI transit times of drugs is suggested.

Synthesis of anisotropic PbS nanoparticles using heterocyclic dithiocarbamate complexes (2012)

We report the synthesis of lead piperidine and lead tetrahydroquinoline dithiocarbamate (DTC) complexes and their use as single source precursors for the preparation of anisotropic PbS nanoparticles. The complexes were thermolysed in coordinating solvents such hexadecylamime (HDA), tri-n-octylphosphine oxide (TOPO), oleylamine (OA) and decylamine (DA) at various reaction temperatures. The variation of the reaction conditions and precursors produced PbS particles with shapes ranging from spheres to cubes and rods. The size of the particles is generally larger than those synthesized by conventional precursor routes. The electron microscopy and X-ray diffraction data confirm the particles to be very crystalline with the dominant cubic rock salt phase present in all samples.
Data input model for virtual reality-aided facility layout (1998)

Abstract An approach to automatically extract three dimensional (3D) models (that is, geometries and topologies) of physical objects in a facility is described. The rationale for this work is its repeated use in efficiently developing databases of 3D objects for applying virtual reality (VR) tools in detailed layout decision support. Obtaining 3D object models can be a challenging task. Sometimes they are available, for example, in a Computer-Aided Design (CAD) database and these can be readily imported into a VR database. But on many occasions one is not so fortunate and these object models have to be created in correlation to an existing or proposed facility, which can be an extremely tedious and time consuming task. A time efficient and economical alternative is to use video camera images, but quickly and accurately capturing the depth information from 2D camera images has so far remained elusive because the existing methodologies are too general purpose and operate at a lower level of abstraction, namely digitized images. We have developed a method for directly inputting 3D objects into VR-aided facility layout models, by integrating the strengths of previously tried and tested technological components: (i) camera calibration; (ii) image processing; (iii) stereo vision; and (iv) Delaunay triangulation. The techniques described here are embedded in a prototype architecture and toolkit called MIRRORS (Methodology for Inputting Raw Recordings into 3D Object Renderings for Stereo). The primary contribution of this paper is that it has been able to design an integrated system to build 3D object models from 2D images. The MIRRORS system has been primarily designed for objects without free-form surfaces and whose shape can be recovered from a relatively nondense set of points.
Partial response class I signaling applied to high density magnetic recording (2002)

For high density magnetic recording systems, equalizing to partial response signals of the form (1-D)(1+D)/sup n/ and applying modulation codes with spectral nulls at DC and the Nyquist frequency have been proposed in Karabed and Siegel (1991). The present authors consider using the same DC/Nyquist-free codes, but equalizing to class I partial response signals with polynomial, (1+D). They find that when the received signal is detected by a Viterbi detector based upon a trellis that combines the equalized channel with the modulation constraint, the simpler detector for class I performs comparably to class IV, (1-D/sup 2/), or extended class IV (1+D-D/sup 2/-D/sup 3/) detectors.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Surface characterization in composite and titanium bonding: Carbon fiber surface treatments for improved adhesion to thermoplastic polymers (1987)

The effect of anodization in NaOH, H2SO4, and amine salts on the surface chemistry of carbon fibers was examined by X-ray photoelectron spectroscopy (XPS). The surfaces of carbon fibers after anodization in NaOH and H2SO4 were examined by scanning transmission electron microscopy (STEM), angular dependent XPS, UV absorption spectroscopy of the anodization bath, secondary ion mass spectrometry, and polar/dispersive surface energy analysis. Hercules AS-4, Dexter Hysol XAS, and Union Carbide T-300 fibers were examined by STEM, angular dependent XPS, and breaking strength measurement before and after commercial surface treatment. Oxygen and nitrogen were added to the fiber surfaces by anodization in amine salts. Analysis of the plasmon peak in the carbon 1s signal indicated that H2SO4 anodization affected the morphological structure of the carbon fiber surface. The work of adhesion of carbon fibers to thermoplastic resins was calculated using the geometric mean relationship. A correlation was observed between the dispersive component of the work of adhesion and the interfacial adhesion.
