Fault-Tolerant Routing With Load Balancing in LeTQ Networks

With the increasing scale of parallel computer interconnection network, the possibility of processor failure or link failure between processors in the network is also increasing. In the design of supercomputers, not only link overhead and communication delay should be taken into account, but also fault-tolerant performance of networks should be emphasized. Locally exchanged twisted cube (<inline-formula><tex-math notation="LaTeX">$LeTQ$</tex-math><alternatives><mml:math><mml:mrow><mml:mi>L</mml:mi><mml:mi>e</mml:mi><mml:mi>T</mml:mi><mml:mi>Q</mml:mi></mml:mrow></mml:math><inline-graphic xlink:href="fan-ieq1-3126627.gif"/></alternatives></inline-formula>) is a newly proposed interconnection network with lower link overhead and shorter diameter. With the increasing scale of supercomputers, fault-tolerant routing is indispensable. In this article, we propose a new load balancing fault-tolerant routing algorithm based on node contraction for <inline-formula><tex-math notation="LaTeX">$LeTQ$</tex-math><alternatives><mml:math><mml:mrow><mml:mi>L</mml:mi><mml:mi>e</mml:mi><mml:mi>T</mml:mi><mml:mi>Q</mml:mi></mml:mrow></mml:math><inline-graphic xlink:href="fan-ieq2-3126627.gif"/></alternatives></inline-formula> networks. The proposed algorithm uses the node shrinkage method to evaluate the priority of nodes. The sending node adaptively adjusts the probability of forwarding packets to the neighbor node according to the priority of the neighbor node and the state of the network. The path can be adapted to the load state of the network. The simulation results show that the fault-tolerant routing algorithm has good performance in throughput and delay.
On the Achievable SINR in MU-MIMO Systems Operating in Time-Varying Rayleigh Fading

Minimizing the symbol error in the uplink of multi-user multiple input multiple output systems is important, because the symbol error affects the achieved signal-to-interference-plus-noise ratio (SINR) and thereby the spectral efficiency of the system. Despite the vast literature available on minimum mean squared error (MMSE) receivers, previously proposed receivers for block fading channels do not minimize the symbol error in time-varying Rayleigh fading channels. Specifically, we show that the true MMSE receiver structure does not only depend on the statistics of the CSI error, but also on the autocorrelation coefficient of the time-variant channel. It turns out that calculating the average SINR when using the proposed receiver is highly non-trivial. In this paper, we employ a random matrix theoretical approach, which allows us to derive a quasi-closed form for the average SINR, which allows to obtain analytical exact results that give valuable insights into how the SINR depends on the number of antennas, employed pilot and data power and the covariance of the time-varying channel. We benchmark the performance of the proposed receiver against recently proposed receivers and find that the proposed MMSE receiver achieves higher SINR than the previously proposed ones, and this benefit increases with increasing autoregressive coefficient.
Study on Surface Heat Transfer Coefficient of Mixture of Nitrogen-Spray Water Eject Quenching under Normal Pressure and High Velocity

During mixture of Nitrogen and spray water ejecting quenching under normal pressure and high velocity, the liquid film that is formed on the surface of specimen to reduce the heat transfer between specimen and quenching media is removed on the one hand; on the other hand, the heat transfer performance of the mixture exceeds that of pure Nitrogen. Because the surface heat transfer coefficient is difficult to measure, according the cooling curve of surface and centre of specimen measured experimentally, the law of surface heat transfer coefficient and specimen temperature is calculated by nonlinear estimate methods and finite difference method based on inverse heat transfer method. The results show that the cooling performance of mixture of Nitrogen and spray water is as well as that of water or oil. During quenching, the surface heat transfer coefficient increases rapidly at begin, and at temperature of 170 °C, the surface heat transfer coefficient decreases. During martensite phase transformation, the latent heat is used to increase drive force of phase transformation and to overcome resistance of phase transformation, thus the martensite phase transformation can fulfill.
Characterization of kinesiological patterns of the frontal kick, mae-geri, in karate experts and non-karate practitioners

Presently, coaches and researchers need to have a better comprehension of the kinesiological parameters that should be an important tool to support teaching methodologies and to improve skills performance in sports. The aim of this study was to (i) identify the kinematic and neuromuscular control patterns of the front kick ( mae-geri ) to a fixed target performed by 14 experienced karate practitioners, and (ii) compare it with the execution of 16 participants without any karate experience, allowing the use of those references in the analysis of the training and learning process. Results showed that the kinematic and neuromuscular activity during the kick performance occurs within 600 ms. Muscle activity and kinematic analysis demonstrated a sequence of activation bracing a proximal-to-distal direction, with the muscles presenting two distinct periods of activity (1, 2), where the karateka group has a greater intensity of activation – root mean square (RMS) and electromyography (EMG) peak – in the first period on Rectus Femoris (RF1) and Vastus Lateralis (VL1) and a lower duration of co-contraction in both periods on Rectus Femoris - Biceps Femoris and Vastus Lateralis - Biceps Femoris (RF-BF; VL-BF). In the skill performance, the hip flexion, the knee extension and the ankle plantar flexion movements were executed with smaller difference in the range of action (ROA) in the karateka group, reflecting different positions of the segments. In conclusion, it was observed a general kinesiological pattern, which was similar in karateka and non-karateka practitioners. However, in the karateka group, the training induces a specialization in the muscle activity reflected in EMG and kinematic data, which leads to a better ballistic performance in the execution of the mae-geri kick, associated with a maximum speed of the distal segments, reached closer to the impact moment, possibly representing more power in the contact.
U-shaped Association Between Apolipoprotein B and All-Cause Mortality: Results from the National Health and Nutrition Examination Surveys

BackgroundApolipoprotein B (apoB), a significant component directly reflecting the number of atherogenic lipoprotein particles, gradually becomes a more conducive indicator to control blood lipids. However, epidemiological evidence on its relationship with mortality is limited, especially with all-cause mortality. MethodsParticipants from the National Health and Nutrition Examination Survey during 2007-2014 were grouped according to the apoB quartiles (15-76, 77-92, 93-110, 111-345mg/dL). We performed Cox proportional hazards models and Kaplan-Meier survival curves to evaluate the relationships of apoB with all-cause and cardiovascular mortality. Restricted cubic spline and piecewise linear regression were performed to detect their non-linear relationships. ResultsIn general, we enrolled 10375 participants among United States adults (mean age 46.3 ± 16.9, 47.88% men). On average, participants were followed up for 69.2 months, among whom 533 (5.14%) and 91 (0.88%) deaths were observed due to all -causes and cardiovascular diseases, respectively. After adjusting for confounders, apoB was independently associated with an elevated risk of cardiovascular death (hazard ratio [HR], 1.13; 95% confidence interval [CI], 1.03-1.24). However, in the third quartile of apoB, the risk of all-cause death decreased significantly (HR, 0.71; 95% CI, 0.56-0.91). Moreover, the non-linear relationship between apoB and all-cause death demonstrated an increased risk at both low and high level apoB concentrations, divided by the threshold point of 108 mg/dl. Conclusion﻿Elevated apoB was significantly associated with an increased risk for cardiovascular mortality, while its association with all-cause mortality was non-linear correlated, with an increased risk at both low and high apoB levels.
Discussion Structure Prediction Based on a Two-step Method

Conversations are often held in laboratories and companies. A summary is vital to grasp the content of a discussion for people who did not attend the discussion. If the summary is illustrated as an argument structure, it is helpful to grasp the discussion’s essentials immediately. Our purpose in this paper is to predict a link structure between nodes that consist of utterances in a conversation: classification of each node pair into “linked” or “not-linked. ” One approach to predict the structure is to utilize machine learning models. However, the result tends to over-generate links of nodes. To solve this problem, we introduce a two-step method to the structure prediction task. We utilize a machine learning-based approach as the first step: a link prediction task. Then, we apply a score-based approach as the second step: a link selection task. Our two-step methods dramatically improved the accuracy as compared with one-step methods based on SVM and BERT.
Synthesis of robust disturbance-feedback strategies by using semi-definite programming

Systems in real-life have to deal with uncertainty in such a manner that a high level of performance is guaranteed under all conditions. The objective in this thesis is to obtain robust strategies that provide an upper bound (worst-case) on the performance of an uncertain system against all allowable disturbances and uncertainties. Semi-definite programming has proven to be an effective tool to design robust control strategies. Traditionally, robust strategies are designed in open-loop form leading to conservative strategies and, therefore, poor performances. This is not surprising as the open-loop control, contrary to feedback control, does not take into account the fact that in the future new measurements will be available. Directly designing state-feedback or output-feedback strategies leads to non-convexity and, hence, computational intractable problems. The synthesis of robust disturbance-feedback strategies can, on the other hand, easily be reformulated as a convex problem. This approach hence bypasses the non-convexity issue while maintaining the advantages of feedback strategies implying that robust disturbance-feedback problems can effectively be solved by semi-definite programming which is the main topic of this thesis. As a key result it is shown that for some systems both sources of conservatism attributed to this approach, namely the relaxation method and the affine parametrization, can be removed at the expense of an increase in computational effort. In addition, the framework for disturbance-feedback strategy synthesis needs to be extended such that it can effectively deal with a large class of model mismatches and uncertainties e.g. system uncertainties and non-linearities. The major obstacle of the implementation of these strategies as receding horizon control strategies is the computational load. Therefore, a gain-scheduling approach is suggested to transfer the computational effort to offline computations. As a result an automatic scheduling of the robust strategies is provided that does not require any online optimization. This work hopefully contributes to the usage of robust disturbance-feedback strategies, not only as a nice academic exercise, but as a valuable engineering tool to design robust strategies and reduce the conservatism so often encountered.
Attitude, Duties and Responsibilities: The Hallmark of Self-Regulators in Business Practicum Program

: Present research in self-regulated learning focused on contextualized task, which allow students to generalized learning. However, few researches delve on the role of the practicum program and the host-training establishment in measuring self-regulated learning among graduating business students. The study investigates the significant presence of self-regulated learners among practicum students through the significant relationship between grade point average and the supervisor rated practicum performance. All the 135 business practicum students from the College of Business Administration for the academic year 2014-2015 participated in the study. The academic performance of the students, from their first year to fourth year demonstrate that the different practicum criteria; duties, quality, punctuality, attitude and grooming correlates with the different year level. The ward hierarchal cluster analysis segments the practicum students between self-regulators and non-self-regulators. Later the variance of analysis confirmed the significant differences across all practicum performance criteria. In addition, the discriminant analysis method shows that that attitude (0.74) and duty (0.503) were helpful in predicting group membership between self-regulating and non-self-regulating students.

Linear models for temperature and power dependence of thermal resistance in Si, InP and GaAs substrate devices

Integrated high-power circuits are typically formed on Si, InP or GaAs substrates. Linear models are derived for the dependence of thermal resistance on temperature dependent thermal conductivity through backside temperature and self-heating. Applied to InP substrate devices, the model predictions are found to be within 5% of measurements for power levels to 3 mW//spl mu/m/sup 2/ and over a 165/spl deg/C substrate temperature range.
Compressed natural gas as an alternative fuel in diesel engines

This project investigates the engine performance and exhaust emission of dual-fuel operation on a single cylinder compression ignition engine. Natural gas is used as the main gaseous fuel with diesel as the pilot fuel to provide a source of ignition. The high compression ratios of diesel engines can be achieved without loss in power together with substantial cost reduction in fuel and conversion kits. Comparative results of dual-fuel operation with conventional diesel fuel through experimental results demonstrated its benefits both in the fields of performance and emission. The engine torque and brake power output show vast improvement and dual-fuel operation is able to achieve a higher thermal efficiency under all operating conditions. The emission levels of polluting gases such as carbon monoxide, oxides of nitrogen (NOx) and carbon dioxide also records an enormous decrease.
Large herbivores facilitate an insect herbivore by modifying plant community composition in a temperate grassland

Abstract Large herbivores often co‐occur and share plant resources with herbivorous insects in grassland ecosystems; yet, how they interact with each other remains poorly understood. We conducted a series of field experiments to investigate whether and how large domestic herbivores (sheep; Ovis aries) may affect the abundance of a common herbivorous insect (aphid; Hyalopterus pruni) in a temperate grassland of northeast China. Our exclosure experiment showed that 3 years (2010–2012) of sheep grazing had led to 86% higher aphid abundance compared with ungrazed sites. Mechanistically, this facilitative effect was driven by grazing altering the plant community, rather than by changes in food availability and predator abundance for aphids. Sheep significantly altered plant community by reducing the abundance of unpalatable forbs for the aphids. Our small‐scale forb removal experiment revealed an “associational plant defense” by forbs which protect the grass Phragmites australis from being attacked by the aphids. However, selective grazing on forbs by sheep indirectly disrupted such associational plant defense, making P. australis more susceptible to aphids, consequentially increasing the density of aphids. These findings provide a novel mechanistic explanation for the effects of large herbivores on herbivorous insects by linking selective grazing to plant community composition and the responses of insect populations in grassland ecosystems.
Frequency of Iatrogenic Sexual Dysfunction Associated with Antihypertensive Compounds

Iatrogenic sexual dysfunction (SD) caused by antihypertensive (AH) compounds, provoking sexual desire, orgasm or arousal dysfunction, is a common clinical adverse event. Unfortunately, it is often underestimated and underreported by clinicians and prescribers in clinical practice, deteriorating the adherence and patient quality of life. The objective of this study was to investigate the frequency of SD in patients treated with different antihypertensive compounds; a real-life naturalistic and cross-sectional study in patients receiving AH treatment was carried out. Method: A total of 256 patients were included in the study (188 males and 68 females who met the inclusion and exclusion criteria). The validated Psychotropic-Related Sexual Dysfunction Questionnaire (PRSexDQ-SALSEX) was transversally applied once at least every two months following the onset of the treatment in order to measure possible AH-related SD. Although the spontaneous reporting of SD was very low (6.81% females/24.8% males), 66.40% of the patients reported impaired sexual function through the SALSEX questionnaire after the treatment onset, as follows: decreased desire (55.8% females/54.2% males), delayed orgasm (42.6%/45.7%), anorgasmia (42.6%/43.6%) and arousal difficulties (53%/59.6%). The average frequency of moderate to severe iatrogenic SD was 66.4% with AH in monotherapy as follows: angiotensin II receptor antagonists (ARBs), 29.8%; calcium antagonists, 40%; diuretics, 42.9%; beta blockers, 43.8%; and angiotensin-converting enzyme (ACE) inhibitors, 77.8%. Combined treatments showed a higher percentage of main SD (70.3%): diuretic + ACE inhibitor, 42.3%; ARB + calcium antagonist, 55.6%; diuretic + calcium antagonist, 68.8%; and diuretic + ARB, 74.2%. The greatest risk factors associated with SD were poor general health, age over 60 with a comorbid coronary or musculoskeletal disease, mood disorder and diuretic +ARB combined therapy. Conclusion: SD is common in patients treated with antihypertensive drugs, and it is still underreported. The most harmful treatment deteriorating sexual function was the combination of diuretic +ARB, while the least harmful was monotherapy with ARBs. More research is needed on the clinical management of this problem to preserve the quality of life of patients and their partners.
A Growth Path for Deep Space Communications

Increased Deep Space Network (DPN) receiving capability far beyond that now available for Voyager is achievable through a mix of increased antenna aperture and increased frequency of operation. In this note a sequence of options are considered: adding midsized antennas for arraying with the existing network at X-band; converting to Ka-band and adding array elements; augmenting the DSN with an orbiting Ka-band station; and augmenting the DSN with an optical receiving capability, either on the ground or in space. Costs of these options are compared as means of achieving significantly increased receiving capability. The envelope of lowest costs projects a possible path for moving from X-band to Ka-band and thence to optical frequencies, and potentially for moving from ground-based to space-based apertures. The move to Ka-band is clearly of value now, with development of optical communications technology a good investment for the future.
