Localising peers in P2P live streaming systems within resource-constrained networks (2012)

The use of locality within peer-to-peer (P2P)network is showing promise, ensuring the construction of ovelay networks that are both economically viable for network operators and scalable, ensuring the successful delivery of content. However, the underlying protocols on which P2P overlays are based were originally designed as a best-effort, non-real time transfer medium which is now rapidly having to evolve in order to better support more time sensitive, real-time video delivery systems. This shift places greater demand on locality mechanisms to ensure the correct balance between bandwidth savings and successful timely playback. In this paper, we continue our work to resolve the strong trade-off resulted from the limited network condition in order to support efficient P2P live streaming services. Based on our findings we propose an OPLoc framework for supporting locality and harmonised play points in a live streaming P2P system. we present our results and analysis of its operation through a series of simulations which measure bandwidth consumption at network egress points, failure rates and each peers' play point relative to the live stream.
Empirical Study of Job Scheduling Algorithms in Hadoop MapReduce (2017)

Abstract Several Job scheduling algorithms have been developed for Hadoop-Map Reduce model, which vary widely in design and behavior for handling different issues such as locality of data, user share fairness, and resource awareness. This article focuses on empirically evaluating the performance of three schedulers: First In First Out (FIFO), Fair scheduler, and Capacity scheduler. To carry out the experimental evaluation, we implement our own Hadoop cluster testbed, consisting of four machines, in which one of the machines works as the master node and all four machines work as slave nodes. The experiments include variation in data sizes, use of two different data processing applications, and variation in the number of nodes used in processing. The article analyzes the performance of the job scheduling algorithms based on various relevant performance measures. The results of the experiments are evident of the performance being affected by the job scheduling parameters, the type of applications, the number of nodes in the cluster, and size of the input data.
Design and Control of an Anthropomorphic Robotic Finger with Multi-point Tactile Sensation (2001)

The goal of this research is to develop the prototype of a tactile sensing platform for anthropomorphic manipulation research. We investigate this problem through the fabrication and simple control of a planar 2-DOF robotic finger inspired by anatomic consistency, self-containment, and adaptability. The robot is equipped with a tactile sensor array based on optical transducer technology whereby localized changes in light intensity within an illuminated foam substrate correspond to the distribution and magnitude of forces applied to the sensor surface plane. The integration of tactile perception is a key component in realizing robotic systems which organically interact with the world. Such natural behavior is characterized by compliant performance that can initiate internal, and respond to external, force application in a dynamic environment. However, most of the current manipulators that support some form of haptic feedback either solely derive proprioceptive sensation or only limit tactile sensors to the mechanical fingertips. These constraints are due to the technological challenges involved in high resolution, multi-point tactile perception. In this work, however, we take the opposite approach, emphasizing the role of full-finger tactile feedback in the refinement of manual capabilities. To this end, we propose and implement a control framework for sensorimotor coordination analogous to infant-level grasping and fixturing reflexes. This thesis details the mechanisms used to achieve these sensory, actuation, and control objectives, along with the design philosophies and biological influences behind them. The results of behavioral experiments with a simple tactilely-modulated control scheme are also described. The hope is to integrate the modular finger into an %engineered analog of the human hand with a complete haptic system.

Japan's Peace Constitution and Its Contribution to International Security (2003)

The development of autonomous driving vehicles has increased the global demand for robust and efficient automotive radar systems. This study proposes an automotive radar-based ego-vehicle speed detection network (AVSD Net) model using convolutional neural networks for estimating the speed of the ego vehicle. The preprocessing and postprocessing methods used for vehicle speed correction are presented in detail. The AVSD Net model exhibits characteristics that are independent of the angular performance of the radar system and its mounting angle on the vehicle, thereby reducing the loss of the maximum detection range without requiring a downward or wide beam for the elevation angle. The ego-vehicle speed is effectively estimated when the range-velocity spectrum data are input into the model. Moreover, preprocessing and postprocessing facilitate an accurate correction of the ego-vehicle speed while reducing the complexity of the model, enabling its application to embedded systems. The proposed ego-vehicle speed correction method can improve safety in various applications, such as autonomous emergency braking systems, forward collision avoidance assist, adaptive cruise control, rear cross-traffic alert, and blind spot detection systems.
Multiuser Scheduling with Orthogonal Space-Division Multiplexing (2010)

The combined Block Digonalization precoding and Geometric Mean Decomposition (BD-GMD) scheme is developed to eliminate the multiuser interference and improve the system performance of bit error rate (BER) in the multiuser multiple input multiple output (MU-MIMO) systems. For the resource allocation and scheduling of BD-GMD system, the equal power allocation and water-filling algorithm for the impact of the system is compared. According to the subspace characteristics, a multiuser scheduling scheme based on maximizing the system throughput with low computational complexity is proposed. In addition, the brute-force search algorithm and conventional greedy algorithm are analyzed and compared with the proposed algorithm. Simulation results show that the proposed algorithm based on the orthogonal projection can reduce the computational complexity while maintaining the system throughput.
Effects of Chemical Blowing Agents on Swelling Properties of Expanded Elastomers (2000)

Two commercial chemical blowing agents, azodicarbonamide (ADC) and oxybisenzenesulphonylhydrazide (OBSH), were used alone and in blends for expanded natural rubber vulcanisates. The expanded rubber vulcanisates were characterised with respect to the apparent foam density, degree of crosslinking, tensile properties and swelling behaviour. For a given blowing agent, the apparent foam density and crosslink density were found to change with blowing agent content. The swelling behaviour greatly changed with OBSH content, but was unaffected by ADC content. The OBSH blowing agent seemed to generate more voids in the vulcanisates as compared to the ADC blowing agent and thus increased swelling. The swelling ratio of the NR vulcanisates having blended blowing agents tended to be more influenced by OBSH than ADC blowing agents.
Alternative Splicing of the Pituitary Adenylate Cyclase-Activating Polypeptide Receptor PAC1: Mechanisms of Fine Tuning of Brain Activity (2013)

Alternative splicing of the precursor mRNA encoding for the neuropeptide receptor PAC1/ADCYAP1R1 generates multiple protein products that exhibit pleiotropic activities. Recent studies in mammals and zebrafish have implicated some of these splice isoforms in control of both cellular and body homeostasis. Here, we review the regulation of PAC1 splice variants and their underlying signal transduction and physiological processes in the nervous system.
The VANTAGE Stormwater Inventory and Management System for Port Moresby, Papua New Guinea (1995)

The VANTAGE system is an integrated PC-based system developed as part of a management review of Port Moresby's stormwater drainage infrastructure. The system uses the MapInfo/MapBasic software to provide a graphical user interface to assist the input, analysis and display of stormwater management information. The VANTAGE system assisted in the preparation of a Master Plan for investment in the upgrading and extension of the drainage system of Port Moresby and in the investigation of the maintenance implications of sediment and waste management strategies. The system also provides easily accessible estimates of flood discharges in future development areas for use in designing the drainage infrastructure. The system can form the basis of an urban services inventory which could include information on water, power and telephone services plus topographic and cadastral information.

Structure, Luminescence, and Adsorption Properties of Two Chiral Microporous Metal−Organic Frameworks (2006)

Two 3D chiral multifunctional microporous MOFs, Zn3(BTC)2(DMF)3(H2O).(DMF)(H2O) (1) and Cd(4)(BTC)3(DMF)2(H2O)2.6(H2O) (2) (H(3)BTC = 1,3,5-benzenetricarboxylic acid and DMF = N,N'-dimethylformamide), have been synthesized in the presence of organic bases tributylamine (TBA) and triethylamine (TEA), respectively. 1 (C(30)H(38)N(4)O(18)Zn(3)) crystallizes in the tetragonal P4(1)2(1)2 space group (a = 13.6929(19) A, c = 50.664(10) A, V = 9499(3) A(3), and Z = 8). 2 (C33H39N2O28Cd4) crystallizes in the tetragonal P4(3)22 space group (a = 10.3503(4) A, c = 52.557(3) A, V = 5630.4(4) A(3), and Z = 4). X-ray crystallography reveals that 1 consists of a 3D open framework with the (6(3))(4)(6(2).8(2).10(2))(6.(4)8(2))(2) topology, but 2 exhibits a 3D open network with the (4(2).5)(2)(4.(4)5.(10)6.(8)7.(4)8(2)) topology. The solid-state excitation-emission spectra show that the strongest excitation peaks for 1 and 2 are at 341 and 319 nm, and their emission spectra mainly show strong peaks at 410 and 405 nm, respectively. The amounts adsorbed of 1 (2) are 169 mg/g (126 mg/g) for H2O, 137 mg/g (102 mg/g) for C2H5OH, and 133 mg/g (99 mg/g) for CH3OH, which are equivalent to the adsorption of about 62 (34) H2O, 20 (11) C2H5OH, and 28 (16) CH3OH per unit cell, respectively.
Quantification of platelet-bound IgG by 125I-Staphylococcal protein A in immune thrombocytopenic purpura and other thrombocytopenic disorders (1984)

In this report we describe the use of an 125I-Staphylococcal protein A (SPA) assay to measure platelet-bound IgG in the evaluation of 62 thrombocytopenic patients. Platelets from 150 normal subjects were found to bind 146 +/- 112 molecules of SPA per platelet (mean +/- 2 SD). Nineteen of 20 patients with untreated immune thrombocytopenia had platelet IgG values above this range, with 15 of 20 having values above 1,000 molecules of SPA per platelet. Patients with immune thrombocytopenic purpura by clinical criteria, but who had failed conventional therapy (corticosteroids or splenectomy), had a wide range of platelet IgG levels: 4 of 20 had normal values, 6 of 20 had minimally elevated levels in the range seen with nonimmune thrombocytopenia, and 10 of 20 had much higher values. Fifteen patients with thrombocytopenia of apparent nonimmune origin and 7 others with chronic stable thrombocytopenia of unknown etiology were found to have platelet IgG levels within or only slightly above the normal range. Because of its simplicity, accuracy, and clinical correlation, the 125I-SPA assay provides an important new approach for studying platelet IgG in thrombocytopenic states. The data obtained with this technique are similar to those found in immune hemolytic anemia and suggest that the platelet-bound IgG so measured has pathophysiologic relevance in immune thrombocytopenic purpura.
A 28Gb/s 4-tap FFE/15-tap DFE serial link transceiver in 32nm SOI CMOS technology (2012)

As exemplified by standards such as OIF CEI-25G, 32G-FC, and next-generation 100GbE, serial link data rates are being pushed up to 25 to 28Gb/s in order to increase I/O system bandwidth. Such speeds represent a near doubling of the state-of-the-art for fully integrated transceivers [1–3]. With scaling no longer providing large gains in device speed, significant design advances must be made to attain these data rates. This paper describes a 28Gb/s serial link transceiver featuring a source-series terminated (SST) driver topology with twice the speed of existing designs, a two-stage peaking amplifier with capacitively-coupled parallel input stages and active feedback, and a 15-tap DFE. The use of capacitive level-shifters allows a single current-integrating summer to drive the parallel paths used for speculating the first two DFE taps.
Lenalidomide in the treatment of multiple myeloma: a review (2008)

Lenalidomide is an immunomodulatory drug derived from thalidomide. It was developed to maximize the anti-inflammatory and anti-neoplasic properties of thalidomide and to reduce its toxicity. The molecular mechanism of action of lenalidomide is unclear, but its therapeutic activity is mainly due to its well defined anti-inflammatory, immunomodulatory, anti-proliferative and anti-angiogenic properties. In relapsed or refractory multiple myeloma (MM), lenalidomide, combined with standard dose dexamethasone, is superior to dexamethasone alone in terms of time to progression, response rate and overall survival. The most commonly reported adverse events include haematological toxicity with manageable neutropenia and thrombopenia. Lenalidomide does not trigger the limiting toxicities of thalidomide: somnolence, neuropathy and constipation. Lenalidomide, in combination with dexamethasone, is indicated for the treatment of MM patients who have received at least one prior therapy and is administered orally at the dose of 25 mg q.d. for 21 days of 28-day cycles. The drug is being investigated for the treatment of newly diagnosed MM. In this review, we summarize the pharmacokinetic, pharmacodynamic and clinical trial data on lenalidomide.
Quasi-optical and spatial power combining (2002)

These techniques have been applied to oscillators, amplifiers, frequency-conversion components, and control circuits. This paper surveys progress in the development of quasi-optical array systems operating in the microwave and millimeter-wave regime, focusing primarily on the progress in power amplifiers.
Bifunctional reagents and protein structure determination. The reaction of phenolic disulfonyl chlorides with lysozyme (1964)

Abstract It was established that phenol‐2,4‐disulfonyl chloride and α‐naphthol‐2, 4‐disulfonyl chloride introduce new intramolecular or tertiary bonds into lysozyme. The phenolic hydroxyl group seems to make the cross linking reagents soluble in aqueous media; it was established that a sulfonylating; species does dissolve prior to hydrolysis but that the chlorosulfonyl groups are hydrolyzed within seconds of dissolution. New covalently linked residues were shown to be introduced by different, spectra. Peptide maps of the lysozyme treated with phenol‐2,4‐disulfonyl chloride. peroxidized, and digested with trypsin showed definite deletions and additions when compared with the control. Partial analysis of the peptides showed that cross linking between ε‐amino groups of lysine residues had occurred. A certain degree of stabilization of lysozyme to inactivation by certain inactivating conditions was noted after treatment with the two reagents. Ultra‐centrifugal analysis of the lysozyme treated with phenol‐2,4‐disulfonyl chloride showed that there was no detectable fraction having a higher molecular weight than native lysozyme. Tentative assignments of positions of cross linking were made.
Leukemic Transformation (2004)

Leukemia results from the uncontrolled accumulation of primitive, poorly differentiated blood cells, and is a consequence of the accumulation of mutations in hematopoietic precursor cells. These mutations include point mutations (single base pair insertions, deletions, or substitutions), gross chromosomal rearrangements such as deletions, insertions, amplifications, and translocations, and epigenetic changes. It seems likely that mutations affecting at least two pathways are required for the development of leukemia. One of these pathways regulates cell accumulation; the second regulates hematopoietic differentiation. Molecularly targeted therapy, which interrupts functions of the leukemogenic proteins generated by mutations, has been developed and shown to be effective for several forms of malignancy. Therefore, it is our hope and belief that a clearer understanding of the mechanism(s) that underlie leukemic transformation will lead to effective new therapies for this dreaded disease.

THE CONSIDERATION OF NON-LINEARITY DURING DEFLECTOMETRIC CONTROL (2008)

The aim of this paper is to show the results obtained with the adoption of deflectometric control during construction process of a medium traffic-volume highway located in the western region of the state of Santa Catarina, Brazil. Two sections with similar pavement structure consisting of granular base and asphalt surface course were analyzed, with one pavement section constructed over a detonated rock subgrade and the other one over a cohesive soil subgrade. Deflection basins were measured in all layers of the pavement structure built, including the subgrade, using Benkelman beam. Dynamic triaxial testing was conducted to determine the resilient behavior of the materials used in the construction. In both segments, with the use of the Kenlayer computer program, load application (equivalent single axle loading with 80KN) was simulated directly upon the subgrade, the base course, and the surface course, thus simulating the measure of deflections in each layer built during the construction process. Such modeling verified that the deflections calculated were identical to the values measured in the field. The work conducted shows that deflection control during the construction process, associated with mechanistic analysis, constitutes a valuable procedure for the analysis and certification of the pavement structure constructed. Also, it is of extreme importance the consideration of the non-linear behavior of the materials employed in pavement construction. The numerical simulations allowed to satisfactorily explain the deflectometric behavior observed in field, thus indicating a great coherence between field measures and laboratory testing.

Enhanced uronic acid content, antioxidant, and anti‐inflammatory activities of polysaccharides from ginseng fermented by <i>Saccharomyces cerevisiae</i> GIW‐1 (2020)

In this study, Panax ginseng was fermented using Saccharomyces cerevisiae GIW-1. The crude ginseng polysaccharides were extracted and purified by DEAE-Sepharose Fast Flow, and the monosaccharide analysis was performed by GC/MS. In addition, the in vitro antioxidant and the anti-inflammatory activities in mice of polysaccharides were determined. Results showed that the uronic acid content of fermented polysaccharide was significantly increased than nonfermented ginseng, showing that the acid polysaccharide was increased after fermentation. And the ginseng polysaccharides between fermented and nonfermented showed different physiological activity after fermentation. Results of the in vitro antioxidant assay showed ginseng polysaccharides after S. cerevisiae GIW-1 fermentation were found to possess higher capacity on scavenging hydroxyl and superoxide anion free radicals. Furthermore, fermented ginseng polysaccharides attenuated increases of liver index and the level of serum AST, and some inflammatory-related factors including TNF-α, IL-1β, and IL-6 in lipopolysaccharide (LPS)-induced mice. Practical applications Microorganism as one of the important tools of biological method has been considered as a more effective and economical way to convert and synthesize natural compounds with more biologically activities. In this paper, we analyze the ginseng polysaccharides after fermented by S. cerevisiae GIW-1. Result showed that fermented ginseng polysaccharides existed superior potency than nonfermented ginseng polysaccharides on antioxidant and anti-inflammatory activities. Moreover, the content of uronic acid in fermented ginseng polysaccharides have increased. These data maybe provide new insight into the natural antioxidants and impetus the development of ginseng in food industry with improving added value of ginseng products.
