K-Adaptability in Two-Stage Robust Binary Programming

Over the last two decades, robust optimization has emerged as a computationally attractive approach to formulate and solve single-stage decision problems affected by uncertainty. More recently, robust optimization has been successfully applied to multistage problems with continuous recourse. This paper takes a step toward extending the robust optimization methodology to problems with integer recourse, which have largely resisted solution so far. To this end, we approximate two-stage robust binary programs by their corresponding K -adaptability problems, in which the decision maker precommits to K second-stage policies, here -and-now, and implements the best of these policies once the uncertain parameters are observed. We study the approximation quality and the computational complexity of the K -adaptability problem, and we propose two mixed-integer linear programming reformulations that can be solved with off-the-shelf software. We demonstrate the effectiveness of our reformulations for stylized instances of supply chain design, route planning, and capital budgeting problems.
System level synthesis for virtual memory enabled hardware threads

Newly introduced ARM-based FPGA platforms enable transparent hardware/software multithreading by providing cache-coherent memory accesses to hardware accelerators. However, the lack of support for virtual memory on the accelerator side hinders the use of off-the-shelf software stacks, such as offered by a Linux-based system, which limits their applicability in a legacy environment. To address this problem, we propose a fully automated high-level synthesis-based source-to-source flow to efficiently support virtual memory in hardware accelerators.
Population-Based Seroprevalence of Malaria in Hormozgan Province, Southeastern Iran: A Low Transmission Area

The seroepidemiological condition of malaria in three main districts of Hormozgan Province, a low transmission area in southeast of Iran, was investigated. Methods. Sera samples (803) were collected from healthy volunteers from the three main districts (Bandar Lengeh in the west, Bandar Abbas in the center, and Bandar Jask in the east) of Hormozgan Province. A questionnaire was used to record the sociodemographic features of the participants during sample collecting. An in-house ELISA test, using crude antigens obtained from cell culture of Plasmodium falciparum, was adapted and used to detect anti-malaria antibodies in the sera. Results. The overall seroprevalence of malaria was 8.7% (70 out of 803 samples). A significant correlation was found between seropositivity and place of residence, where the highest rate of seropositivity was seen in Bandar Lengeh (west of the province). The highest seroprevalence of malaria (13.2%) was seen in the age group of 11–20 years and also in low educated individuals. Correlation between seropositivity and gender, age, and educational levels of the participants was statistically significant (P < 0.05). Conclusion. Findings of this study indicate that the rate of seropositivity to malaria in this area is not high and this might be linked to the success of malaria control programs during the last decades in the region.
The Evolution of Consumption Structure and Industrial Structure — — Empirical Research Based on VAR Model

Abstract: Using data from statistical yearbook from 1978 to 2007, the authors construct a VAR model consist of variables of consumption structure, income level of urban residents, secondary industry and tertiary industry. The empirical method of VAR model is used to study on the dynamic characteristic and interaction relationship between consumption structure and industrial structure. By means of model specification, Granger causality test, variance decomposition and cointegration test, the results indicate that consumption structure can affect secondary industry upgrading. Furthermore, income of urban residents and industrial structure has two-way causality. That indicates in Jilin province, we should raise income level of urban residents to promote industry and consumption upgrading.
Cosmic Ray Production of 6Li by Virialisation Shocks in the Early Milky Way

Abstract The energy dissipated by virialisation shocks during hierarchical structure formation of the Galaxy can exceed that injected by concomitant supernova (SN) explosions. Cosmic rays (CRs) accelerated by such shocks may therefore dominate over SNe in the production of 6Li through α + α fusion without co-producing Be and B. This process can give a more natural account of the observed 6Li abundance in metal-poor stars compared to standard SN CR scenarios. Future searches for correlations between the 6Li abundance and the kinematic properties of halo stars may constitute an important probe of how the Galaxy and its halo formed. Furthermore, 6Li may offer interesting clues to some fundamental but currently unresolved issues in cosmology and structure formation on sub-galactic scales.
Dynamic Progressive Triangle-Quadrilateral Meshes

We present an extension of the original progressive mesh algorithm for large dynamic meshes that contain a mix of triangle and quadrilateral elements. The demand for this extension comes from the visualisation of dynamic finite element simulations, such as car crashes or metal sheet punch operations. These methods use meshes, which consist mainly of quadrilaterals, due to their increased numerical stability during the simulation. Furthermore, these meshes have a dynamic geometry with about 25 to 100 animation steps. Accordingly, we extend the original progressive mesh algorithm in two aspects: First, the edge collapse operation is extended for meshes with a mixture of triangle and quadrilateral elements. Second, we present an algorithm on how to extend quadric error metrics for the simplification of large dynamic meshes with many animation steps. The results are dynamic progressive triangle-quadrilateral meshes – a progressive multi-resolution mesh structure that has two interactive degrees of freedom: simulation time and mesh resolution. We show that our method works on meshes with up to one million vertices and 25 animation steps. We measure the approximation error and compare the results to other algorithms.
The relationship between ambient particulate matter and respiratory mortality: a multi-city study in Italy

The association of air pollutants with natural and respiratory mortality has been consistently reported. However, several aspects of the relationship between particulate matter with a 50% cut-off aerodynamic diameter of 10 &mgr;m (PM10) and respiratory mortality require further investigation. The aim of the present study was to assess the PM10–respiratory mortality association in Italy and examine potentially susceptible groups. All deaths from natural (n=276,205) and respiratory (n=19,629) causes among subjects aged ≥35 yrs in 10 northern, central and southern Italian cities in 2001–2005 were included in the study. Pollution data for PM10, nitrogen dioxide and ozone were also obtained. A time-stratified case-crossover analysis was carried out. Different cumulative lags were selected to analyse immediate, delayed, prolonged and best-time effects of air pollution. The shape of the exposure–response curve was analysed. Age, sex, chronic conditions and death site were investigated as potential effect modifiers. We found a 2.29% (95% CI 1.03–3.58%) increase in respiratory mortality at 0–3 days lag. The increase in respiratory mortality was higher in summer (7.57%). The exposure–response curve had a linear shape without any threshold. Sex and chronic diseases modified the relationship between particular matter (PM) and respiratory mortality. The effect of PM on respiratory mortality was stronger and more persistent than that on natural mortality. Females and chronic disease sufferers were more likely to die of a respiratory disease caused by air pollution than males and healthy people.
Multi-target adaptive A

Agents often have to solve series of similar path planning problems. Adaptive A* is a recent incremental heuristic search algorithm that solves such problems faster than A*, updating a heuristic function (also known as h-values) using information from previous searches. In this paper, we address path planning with multiple targets on Adaptive A* framework. Although we can solve such problems by calculating the optimal path to each target, it would be inefficient, especially when the number of targets is large. We consider two cases whose objectives are (1) an agent reaches one of the targets, and (2) an agent has to reach all of the targets. We propose several methods to solve such problems keeping consistency of a heuristic function. Our experiments show that the proposed methods properly work on an application, i.e., maze problems.

The paper present the structure of an active parallel filter for distorting regime and reactive power compensation. The active power filter control is based on generalized reactive power theory. The authors present the modeling of parallel active filter based on this theory and the simulation results in MATLAB-SIMULINK for two methods of power filter regulator. One of this is based on instantaneous reactive power (TGPI_Q) and the other is based on instantaneous active power (TGPI_P).
Simple On-Demand Overlays for Reliable Real-Time Traffic in Enterprise Networks

— Real-time applications such as IP Telephony demand strict quality of service (QoS) from the underlying network. As more enterprises deploy IP Telephony, it is becoming imperative to signiﬁcantly improve the network reliability as seen by these applications. As such, we recently proposed a practical overlay architecture, ORBIT ( O verlays providing R eliability for B etter I P T elephony). Our architecture consists of intelligent endpoints and independent relays. The endpoints rapidly detect network QoS degradation and ﬁnd alternate application layer paths (mid-call) to the destination that avoid the problems. The overlay is activated only on-demand and the system is easy to deploy. In this paper, we compare two measurement techniques, describe our initial prototype and provide empirical results of the prototype’s reaction time to network problems that indicate rapid response to QoS degradation.
Interrater Reliability of Chinese Medicine Diagnosis in People with Prediabetes

Background. Achieving reproducibility in research design is challenging when patient cohorts under study are inconsistently defined. Traditional Chinese medicine (TCM) diagnosis is one example where inconsistency between practitioners has been found. We hypothesise that the use of a validated instrument may improve consistency. Biochemical biomarkers may also be used enhance reliability. Methods. Twenty-seven participants with prediabetes were assessed by two TCM practitioners using a validated instrument (TEAMSI-TCM). Inter-rater reliability was summarised using percentage agreement and the kappa coefficient. One-way ANOVA and Tukey's post hoc test were used to test links between TCM diagnosis and biomarkers. Results. The two practitioners agreed on primary diagnosis of 70% of participants. kappa = 0.56 (P < 0.001). The three predominant TCM diagnostic patterns for people with prediabetes were Yin deficiency, Qi and Yin deficiency and Spleen qi deficiency. The Spleen Qi deficiency with Damp cohort had statistically significant higher fasting glucose, higher insulin, higher insulin resistance, higher HbA1c and lower HDL than those with Qi and Yin deficiency. Conclusions. Using the TEAMSI-TCM resulted in moderate interrater reliability between TCM practitioners. This study provides initial evidence of variation in the biomarkers of people with prediabetes according to the different TCM patterns which may suggest a route to further improving interrater reliability.
Cardiac Benefits of Fish Consumption May Depend on the Type of Fish Meal Consumed: The Cardiovascular Health Study

Background—Few studies have examined associations of fish consumption with ischemic heart disease (IHD) risk among older adults or how different types of fish meals relate to IHD risk. Methods and Results—In a population-based prospective cohort study, usual fish consumption was ascertained at baseline among 3910 adults aged ≥65 years and free of known cardiovascular disease in 1989 and 1990. Consumption of tuna and other broiled or baked fish correlated with plasma phospholipid long-chain n-3 fatty acids, whereas consumption of fried fish or fish sandwiches (fish burgers) did not. Over 9.3 years’ mean follow-up, there were 247 IHD deaths (including 148 arrhythmic deaths) and 363 incident nonfatal myocardial infarctions (MIs). After adjustment for potential confounders, consumption of tuna or other broiled or baked fish was associated with lower risk of total IHD death (P for trend=0.001) and arrhythmic IHD death (P =0.001) but not nonfatal MI (P =0.44), with 49% lower risk of total IHD death and 58% lower risk of arrhythmic IHD death among persons consuming tuna/other fish 3 or more times per week compared with less than once per month. In similar analyses, fried fish/fish sandwich consumption was not associated with lower risk of total IHD death, arrhythmic IHD death, or nonfatal MI but rather with trends toward higher risk. Conclusions—Among adults aged ≥65 years, modest consumption of tuna or other broiled or baked fish, but not fried fish or fish sandwiches, is associated with lower risk of IHD death, especially arrhythmic IHD death. Cardiac benefits of fish consumption may vary depending on the type of fish meal consumed.
Nicotinic Acetylcholine Receptors in the Anterior, but Not Posterior, Ventral Tegmental Area Mediate Ethanol-Induced Elevation of Accumbal Dopamine Levels

Ethanol-induced elevations of accumbal dopamine levels have been linked to the reinforcing properties of the drug. However, it has not yet been demonstrated where the primary point of action of ethanol is in the mesolimbic dopamine system, and there appear to be conflicting findings depending on methodology (electrophysiology, microdialysis, or intracranial self-administration). We have suggested that ethanol acts in the nucleus accumbens (nAc), where it activates a neuronal loop involving ventral tegmental nicotinic acetylcholine receptors (nAChRs) to elevate dopamine levels in the nAc. Application of ethanol in the nAc results in elevated dopamine levels in the same brain region, whereas administration in the anterior ventral tegmental area (VTA) fails to influence dopamine output. In the present study, we were able to repeat these findings. In addition, application of ethanol in the posterior VTA also failed to influence nAc dopamine levels. Perfusion of the nAChR antagonist mecamylamine in the anterior VTA completely blocked the elevation of accumbal dopamine levels observed after ethanol perfusion in nAc, whereas mecamylamine in the posterior VTA had no effect. To detect a possible influence on phasic dopamine release, the dopamine transporter inhibitor nomifensine was included in the accumbal perfusate. In addition, under these conditions, ethanol in the anterior or posterior VTA failed to influence dopamine release in the nAc. These results support previous suggestions of distinct functions of the anterior and posterior VTA and give further evidence for our hypothesis of a nAc-anterior VTA-nAc neuronal circuitry involved in the dopamine-activating effects of ethanol.
Energy Savings in Metropolitan Railway Substations Through Regenerative Energy Recovery and Optimal Design of ATO Speed Profiles

Traffic operation has a significant impact on energy consumption in metro lines and thus it is important to analyze strategies to minimize it. In lines equipped with Automatic Train Operation systems (ATO), traffic regulation system selects one ATO speed profile on line among a preprogrammed set of optimized speed profiles. Previous works only minimize the energy demanded by the train in pantograph without considering energy savings measured at substations due to regenerative energy in detail. The main objective of this work is to design optimal ATO speed profiles of metro trains taking into account the energy recovered from regenerative brake in order to minimize the net energy at substations. A model of a train with an on-board energy storage device as well as a network model for estimating the energy recovered by the train is presented. Different scenarios are analyzed to assess the achievable energy savings due to possible investments such as installing power inverters or storage devices and energy savings due to the optimal design of ATO speed profiles are estimated. A real line of the Madrid Underground has been considered obtaining comparative results to facilitate an evaluation of the most advantageous scenario and possible investment. A future application would be the optimal design of driving for the newest train signaling system communications-based train control (CBTC). The CBTC improves train operation and control, due to continuous communication with each train. However, its features have not been taken full advantage yet to reduce the energy consumption. The proposed method could be applied to design and execute in real time the most energy-efficient driving according to the traffic and electrical situation of the line.
The Performance Analysis of Concatenated Turbo Coding Scheme over the DVB-T Transmission Channel

This paper outlines the application of orthogonal frequency-division multiplexing (OFDM) in digital communication channel, then studies the turbo codes, mentions the concatenation of turbo codes and Reed-Solomon (RS) codes and analysis the performances of the new concatenated forward error correct (FEC) scheme applied to an OFDM system based on the digital terrestrial video broadcasting (DVB-T) scheme. The results are compared with the standard DVB-T convolutional codes performances on added white Gaussian noise (AWGN) channels. The simulation results shown that performances by employing turbo codes with only a few numbers of iterations the overall system can be improved significantly. These results are obtained applying an appropriate interleaver technique in the concatenated FEC procedure.
Embedded virtualization for the design of secure IoT applications

Embedded virtualization has emerged as a valuable way to reduce costs, improve software quality, and decrease design time. Additionally, virtualization can enforce the overall system’s security from several perspectives. One is security due to separation, where the hypervisor ensures that one domain does not compromise the execution of other domains. At the same time, the advances in the development of IoT applications opened discussions about the security flaws that were introduced by IoT devices. In a few years, billions of these devices will be connected to the cloud exchanging information. This is an opportunity for hackers to exploit their vulnerabilities, endangering applications connected to such devices. At this point, it is inevitable to consider virtualization as a possible approach for IoT security. In this paper we discuss how embedded virtualization could take place on IoT devices as a sound solution for security.
Academic achievement following childhood onset brain injury

The degree of academic achievement following early onset brain injury is poorly understood. Furthermore, it is unclear if academic success can be predicted by age of onset or other lesion variables (e.g., size, laterality). The purpose of the current study was to describe patterns of academic achievement in individuals with childhood-onset focal brain lesions and to determine the role of variables in the plasticity or vulnerability of the developing brain with regard to achievement. Academic achievement data were collected from 58 individuals with childhood-onset focal brain lesions. The participants’ reading, spelling, and arithmetic scores, as measured by the Wide Range Achievement Test, were analyzed in relation to several neuroanatomical variables, including lesion laterality, lesion site, and lesion size. The relationship between achievement and gender, age of onset, etiology, age at testing, and time since lesion onset was also identified. As a group, participants’ achievement scores did not differ from normative data, and the majority of the sample demonstrated adequate skills in each domain. However, the frequency of deficits was larger than expected when compared to base rates, suggesting vulnerability to early insult. Achievement scores were correlated with intelligence scores, but did not differ based on lesion laterality, lesion site, age of onset, or etiology. Size of lesion was significantly correlated with reading and spelling but not with arithmetic outcomes. Gender differences were identified, with males performing significantly better on the arithmetic measure than females. The age of onset, age at testing, and time since lesion onset were not correlated with achievement scores in any domain. No interactions were found between lesion laterality and gender or lesion site and lesion laterality. An interaction between gender and lesion site was found, but the significance of the finding was unclear. The current findings provide mixed evidence for the plasticity-vulnerability debate, as many individuals were able to achieve adequate academic skills whereas others demonstrated significant impairments. Further research is
