Joint Sleep Scheduling and Mode Assignment in Wireless Cyber-Physical Systems

Recent years have witnessed the deployment of wireless Cyber-Physical Systems(CPS) for a variety of important applications.A key requirement for wireless CPS systems is to sustain a long lifetime on limited power supplies. At the same time, due to the criticality of CPS applications, many computation and communication tasks must be finished within timing constraints to avoid undesirable or even catastrophic consequences. %%Minimizing network-wide energy consumption is a key issue in designing%cyber-physical systems.While a lot of work has been done to manage energy consumption on single processor real-time systems,little work has been done in network-wide energy consumption management for real-time applications.Existing work on network-wide energy minimization assumes that the underlying network is always connected, which is not consistent with the practice in which wireless nodes often turn off their network interfaces in a sleep schedule to reduce energy consumption. %Moreover, existing sleep scheduling techniques are unaware of computation status and often%lead to unnecessary wakeup overhead. %In this paper, we propose solutions to minimize%network-wide energy consumption for real-time tasks with precedence%constraints executing on wireless cyber-physical systems.This paper jointly considers the radio sleep scheduling of wireless nodes and the execution modes of processors. Based on wireless network topologies, different schemes are proposed to minimize energy consumption while guaranteeing the timing and precedence constraints. When the precedence graph is a tree, optimal result on energy management is achieved. The experiments show that our approach significantly reduces total energy consumption compared with the previous work.
Selective Immunolesions of Cholinergic Neurons in Mice: Effects on Neuroanatomy, Neurochemistry, and Behavior

The ability to selectively lesion mouse basal forebrain cholinergic neurons would permit experimental examination of interactions between cholinergic functional loss and genetic factors associated with neurodegenerative disease. We developed a selective toxin for mouse basal forebrain cholinergic neurons by conjugating saporin (SAP), a ribosome-inactivating protein, to a rat monoclonal antibody against the mouse p75 nerve growth factor (NGF) receptor (anti-murine-p75). The toxin proved effective and selective in vitro andin vivo. Intracerebroventricular injections of anti-murine-p75-SAP produced a dose-dependent loss of choline acetyltransferase (ChAT) activity in the hippocampus and neocortex without affecting glutamic acid decarboxylase (GAD) activity. Hippocampal ChAT depletions induced by the immunotoxin were consistently greater than neocortical depletions. Immunohistochemical analysis revealed a dose-dependent loss of cholinergic neurons in the medial septum (MS) but no marked loss of cholinergic neurons in the nucleus basalis magnocellularis after intracerebroventricular injection of the toxin. No loss of noncholinergic neurons in the MS was apparent, nor could we detect loss of noncholinergic cerebellar Purkinje cells, which also express p75. Behavioral analysis suggested a spatial learning deficit in anti-murine-p75-SAP-lesioned mice, based on a correlation between a loss of hippocampal ChAT activity and impairment in Morris water maze performance. Our results indicate that we have developed a specific cholinergic immunotoxin for mice. They also suggest possible functional differences in the mouse and rat cholinergic systems, which may be of particular significance in attempts to develop animal models of human diseases, such as Alzheimer's disease, which are associated with impaired cholinergic function.
The aggregation of Chauliognathus species (Coleoptera, Cantharidae) and its possible role for coexistence and mimicry

The relative population sizes of a species complex of Chauliognathus are reported, as well as their spatial distribution associated with different patches of food plants. Field work was done at Fazenda Santa Isabel, municipality of Guaiba, State of Rio Grande do Sul, Brazil. The results suggest that two mechanisms account for the reduction in food competition among the species involved: one is asynchrony in the appearance of the species in the area, and the other is aggregation in different patches of food plants. Since the species here reported show a similar colour pattern (yellow-black) the possibility of the occurrence of serial mimicry in this complex of species is dicussed.
HISTOCHEMICAL INVESTIGATION OF ALCOHOL DEHYDROGEHASE , GLUTAMATE DEHYDROGENASE AND α-ESTERASE ACTIVITY IN LOW TEMPERATURE STRESSED TOBACCO CALLUS AND THE EFFECT OF CYTOKININS

The influence of the synthetic phenylurea cytokinin 4-PU-30 and of the adenin cytokinin kinetin on the chilling and freezing stress of tobacco callus was studied histochemically. The investigations were carried out immediately after the low-temperature stress and after 20 days cultivation. It was established that alcohol dehydrogenase and glutamate dehydrogenase activities decreased but esterase activity rose drastically after chilling and freezing in the presence of both cytokinins in the nutrient medium. After 20 days the alcohol dehydrogenase activity was restored more rapidly in the presence of 4-PU-30 than in the presence of kinetin in the nutrient medium. A tendency of restoring normal glutamate dehydrogenase, and α-esterase activities after freezing was observed only in the presence of 4-PU-30. It was concluded that 4-PU-30 added to the nutrient medium manifests higher chilling and freezing antistress activity as compared to kinetin.
Untreated Mild Hyperglycemia During Pregnancy and Anthropometric Measures of Obesity in Offspring at Age 5–7 Years

OBJECTIVE Obesity in the offspring of women with hyperglycemia during pregnancy has been reported, but the results are conflicting. This study examined the association of hyperglycemia during pregnancy and anthropometry in 5- to 7-year-old offspring whose mothers participated in the Hyperglycemia and Adverse Pregnancy Outcome (HAPO) Study at the Belfast Centre. RESEARCH DESIGN AND METHODS Women in the HAPO study underwent a 75-g oral glucose tolerance test (OGTT) at approximately 28 weeks of gestation. Mothers and caregivers remained blinded to the results unless the fasting plasma glucose (FPG) concentration was >5.8 mmol/L or the 2-h plasma glucose (2hPG) concentration was >11.1 mmol/L. Offspring weight, height, and skinfold thicknesses (triceps, subscapular, and suprailiac) were measured at age 5–7 years. Overweight, obesity, and extreme obesity were defined as a BMI z score ≥85th, ≥95th, and ≥99th percentile, respectively, based on the 1990 British Growth Standard. RESULTS Belfast HAPO offspring (n = 1,320, 82%) aged 5–7 years attended for follow-up. With use of multiple regression, maternal FPG, 1h PG, and 2hPG did not show any relation to offspring BMI z score or offspring skinfold sum independent of maternal BMI at OGTT and offspring birth weight z score. This lack of association with maternal glycemia persisted with the offspring BMI z score expressed as ≥85th, ≥95th, or 99th percentile and the sum of skinfolds expressed as ≥90th percentile specific for sex. The initially significant relation between FPG and all offspring adiposity measures was explained by maternal BMI at the OGTT. CONCLUSIONS After adjustment for maternal BMI at the OGTT, higher maternal FPG concentration during pregnancy (short of diabetes) is no longer a risk factor for obesity, as reflected by BMI and the sum of skinfolds in offspring aged 5–7 years.
Multiphoton microscopy in life sciences

Near infrared (NIR) multiphoton microscopy is becoming a novel optical tool of choice for fluorescence imaging with high spatial and temporal resolution, diagnostics, photochemistry and nanoprocessing within living cells and tissues. Three‐dimensional fluorescence imaging based on non‐resonant two‐photon or three‐photon fluorophor excitation requires light intensities in the range of MW cm−2 to GW cm−2, which can be derived by diffraction limited focusing of continuous wave and pulsed NIR laser radiation. NIR lasers can be employed as the excitation source for multifluorophor multiphoton excitation and hence multicolour imaging. In combination with fluorescence in situ hybridization (FISH), this novel approach can be used for multi‐gene detection (multiphoton multicolour FISH). Owing to the high NIR penetration depth, non‐invasive optical biopsies can be obtained from patients and ex vivo tissue by morphological and functional fluorescence imaging of endogenous fluorophores such as NAD(P)H, flavin, lipofuscin, porphyrins, collagen and elastin. Recent botanical applications of multiphoton microscopy include depth‐resolved imaging of pigments (chlorophyll) and green fluorescent proteins as well as non‐invasive fluorophore loading into single living plant cells.
Four SNPs on Chromosome 9p21 in a South Korean Population Implicate a Genetic Locus That Confers High Cross-Race Risk for Development of Coronary Artery Disease

Objective—Recent genome-wide association studies have identified 4 SNPs on chromosome 9p21 associated with CAD (rs10757274 and rs2383206) and myocardial infarction (MI: rs2383207 and rs10757278) in White populations in Northern Europe and North America. We aimed to determine whether this locus confers significant susceptibility to CAD in a South Korean population, and thus cross-race susceptibility to CAD. Methods and Results—We performed a case-control association study with 611 unrelated CAD patients and 294 normal controls from South Korea. Allelic associations of SNPs and SNP haplotypes with CAD were evaluated. Multivariate logistic regression analysis was used to adjust effects of clinical covariates. We found that 4 SNPs on chromosome 9p21 were associated with susceptibility to CAD in a South Korean population. The association remained significant after adjusting for significant clinical covariates (P=0.001 to 0.024). We identified one risk haplotype (GGGG; P=0.017) and one protective haplotype (AAAA; P=0.007) for development of CAD. Further analysis suggested that the SNPs probably confer susceptibility to CAD in a dominance model (covariates-adjusted P=0.001 to 0.024; OR=2.37 to 1.54). This represents the first study that expands association of these 9p21 SNPs with CAD beyond White populations. Conclusion—Chromosome 9p21 is an important susceptibility locus that confers high cross-race risk for development of CAD.
A stable non-BPS configuration from intersecting branes and antibranes

We describe a tachyon-free stable non-BPS brane configuration in type-IIA string theory. The configuration is an elliptic model involving rotated NS5-branes, D4-branes and anti-D4 branes, and is dual to a fractional brane-antibrane pair placed at a conifold singularity. This configuration exhibits an interesting behaviour as we vary the radius of the compact direction. Below a critical radius the D4 and anti-D4 branes are aligned, but as the radius increases above the critical value the potential between them develops a minimum away from zero. This signals a phase transition to a configuration with finitely separated branes.
Microarchitecture optimizations for exploiting memory-level parallelism

The performance of memory-bound commercial applications such as databases is limited by increasing memory latencies. In this paper, we show that exploiting memory-level parallelism (MLP) is an effective approach for improving the performance of these applications and that microarchitecture has a profound impact on achievable MLP. Using the epoch model of MLP, we reason how traditional microarchitecture features such as out-of-order issue and state-of-the-art microarchitecture techniques such as runahead execution affect MLP. Simulation results show that a moderately aggressive out-of-order issue processor improves MLP over an in-order issue processor by 12-30%, and that aggressive handling of loads, branches and serializing instructions is needed to attain the full benefits of large out-of-order instruction windows. The results also show that a processor's issue window and reorder buffer should be decoupled to exploit MLP more efficiently. In addition, we demonstrate that runahead execution is highly effective in enhancing MLP, potentially improving the MLP of the database workload by 82% and its overall performance by 60%. Finally, our limit study shows that there is considerable headroom in improving MLP and overall performance by implementing effective instruction prefetching, more accurate branch prediction and better value prediction in addition to runahead execution.
Collaborative content enrichment in multilingual Europe , European Schoolnet approach on educational resources

In this paper, we describe the first steps of the content enrichment approach that European Schoolnet, with its partners in the MELT project, has taken to allow users collaboratively annotate the existing learning resources. The paper will briefly outline the MELT strategy for co-existence of structured and unstructured learning resources metadata (LOM), then it will outline the envisaged enrichment services for multilingual folksonomic approach. Moreover, we give the first evaluations on multilingual user-given free-keywords on learning resources which leads us to outline our approach to manage tags in multiple languages within the MELT federation of learning resource repositories.
Image Colorization Using Discriminative Textural Features

This paper presents a novel approach to scribblebased image colorization. In the work reported here we have explored how to exploit the textural information to improve this process. For every scribbled image we extract the most discriminative features using linear discriminant analysis (LDA). After that, the whole image is projected onto a discriminative textural feature space. Our main contribution lies in propagating the color in the feature space domain rather than using the luminance channel. The presented experimental validation confirms the importance of using textural information and show that our method significantly improves the obtained colorization results.
The development and evaluation of aces : a web-based training to enhance school nurses' attitude, subjective norm, perceived behavioral control, and intention to provide adolescent cessation services

A substantial amount of research supports the provision of adolescent tobacco cessation services, and school nurses are situated to effectively provide these services in the school-based setting. However, few evidence-based adolescent cessation tools and trainings exist. The Adolescent Cessation in Every School (ACES) toolkit and training were developed by the researcher to fill this gap. The Theory of Planned Behavior (TPB) served as a guide for both the development and the evaluation of ACES. The purpose of this study was to test the efficacy and acceptability of the Adolescent Cessation in Every School (ACES) training video to enhance Missouri school nurses’ attitude, subjective norm, perceived behavioral control, and intention to provide adolescent tobacco cessation services. A total of 122 school nurse participants completed the pre-intervention questionnaire (time 0). Participants were then randomized to immediate intervention (II) or waitlist control (WC). The II group received the intervention and post-intervention questionnaire at time 1, while the WC group completed a second pre-intervention questionnaire. The WC group completed the intervention and post-intervention questionnaire at time 2. Each group also received a four-week follow-up questionnaire (time 3 for II, time 4 for WC). Reliability analyses using Cronbach’s alpha were conducted for each TPB construct at each timepoint. Dependent sample T-tests analyzed constructs at pre-intervention and at post-intervention and follow-up. Independent T-tests of TPB constructs were conducted by group and timepoint. Point-biserial correlational analyses were conducted for each theory construct scale at pre-intervention, postintervention, and follow-up.

Promoting employees’ learning from errors by inclusive leadership: Do positive mood and gender matter?

Purpose In today’s complex and challenging work environment, employees’ learning from errors has become critical to organizations’ survival and success. While the literature has highlighted the importance of inclusive leadership for learning behavior in organizations, research on how inclusive leadership promotes employees’ learning from errors has been limited. Therefore, the purpose of this paper is to fill this gap by developing and testing a moderated mediation model that emphasizes the key roles of positive mood and gender in the relationship between inclusive leadership and employees’ learning from errors. Design/methodology/approach A multi-time survey method was used in this study to collect data from 202 full-time employees working in China. Findings The hypothesized moderated mediation model in this study was supported. Inclusive leadership facilitated employees’ learning from errors through employees’ positive mood, and employees’ gender moderated both the direct relationship between inclusive leadership and employees’ positive mood and the indirect relationship between inclusive leadership and employees’ learning from errors through employees’ positive mood: the relationships were stronger for female employees than for male employees. Originality/value By incorporating the social role theory into the affective events theory framework, this study may help to open the “black box” of the relationship between inclusive leadership and employees’ learning from errors by explicating the importance of positive mood and gender, thereby shedding light on the timely issues of inclusive leadership, mood, and learning from errors in the workplace.
Multiple Circulating Cytokines Are Coelevated in Chronic Obstructive Pulmonary Disease

Inflammatory biomarkers, including cytokines, are associated with COPD, but the association of particular circulating cytokines with systemic pathology remains equivocal. To investigate this, we developed a protein microarray system to detect multiple cytokines in small volumes of serum. Fourteen cytokines were measured in serum from never-smokers, ex-smokers, current smokers, and COPD patients (GOLD stages 1–3). Certain individual circulating cytokines (particularly TNFα and IL-1β) were significantly elevated in concentration in the serum of particular COPD patients (and some current/ex-smokers without COPD) and may serve as markers of particularly significant systemic inflammation. However, numerous circulating cytokines were raised such that their combined, but not individual, elevation was significantly associated with severity of disease, and these may be further indicators of, and contributors to, the systemic inflammatory manifestations of COPD. The coelevation of numerous circulating cytokines in COPD is consistent with the insidious development, chronic nature, and systemic comorbidities of the disease.
Ascorbic Acid Concentrations in Orange Juice Using Different Storage Methods

Citrus fruits such as oranges contain high vitamin C (ascorbic acid) levels. These fruits are essential dietary supplements that provide nutritional values and health benefits to its consumers. Vitamin C is also a valuable food source that could prevent the dreadful disease of scurvy. Studies have been conducted to measure the ascorbic acid levels from citrus fruits such as oranges. Moreover, previous studies have also reviewed the factors that can influence an orange’s vitamin C content. It has been proven that citrus fruits can lose vitamin C content due to their storage methods. However, there are possible secondary chemical reactions that may also influence the loss of their vitamin C due to their aging process. After completing this research project, it was noticed that the storage method can either speed up or slow down the ascorbic acid degradation rate. On the other hand, the vitamin C concentration did not vary among the four different storage methods: glass jar container, wrapping in wax paper, clothing bag and the control without any wrapping or container method.

WearableSensorySystemfor Robotic Prosthesis LukaAmbrozic , MajaGoršic , SebastjaňSlajpah ,

The paper presents a wearable sensory system aimed at tracking of motion parameters and estimation of kinematic data of the wearer for use in controlling active lower-limb ortho-prostheses. The sensory system comprises inertial and magnetic measurement units (IMUs) attached to body segments and sensorized insoles worn inside sneaker shoes. Through sensory fusion, the IMUs data is used to produce estimates of segment orientations, while the insoles provide information on vertical ground reaction force amplitude and distribution. The paper outlines the principles of the algorithms and show the evaluation of them. Algorithms use both reference and wearable sensory data to extract information about the subject's kinematics, movement type and phase and track selected biomechanical stability descriptors. The paper discusses preliminary experimental results of the proposed algorithms.
Low-complexity blind beamforming based on cyclostationarity

A blind adaptive beamformer with real-valued weights for cyclostationary signals is proposed by introducing a preprocessing stage. It is proved that the optimum weight vector of the proposed method is real-valued. Thus we can discard the imaginary part of the weight vector during the update process, which reduces the computational complexity of the algorithm. Moreover, since the optimum solution is real-valued, a result closer to the optimum one is reached, leading to a much increased convergence rate.
A note on the complexity of some multiobjective A* search algorithms

This paper studies the complexity of two different algorithms proposed as extensions of A* for multiobjective search: MOA* and NAMOA*. It is known that, for any given problem, NAMOA* requires the consideration of no more alternatives than MOA* when provided with the same heuristic information. In this paper we show that, in fact, expansions performed by MOA* can be many more than those demanded by the problem, and hence than those performed by NAMOA*. More specifically, we show a sequence of problems whose size grows linearly such that the number of expansions performed by NAMOA* grows also linearly, but the number of expansions performed by MOA* grows exponentially. Therefore, there are problems where NAMOA* performs exponentially better than MOA*.
Enabling multimedia using resource-constrained video processing techniques: A node-centric perspective

Successful proliferation of multimedia-enabled devices and advances in very large-scale integration (VLSI) technology has spawned new research efforts in migrating video processing applications onto ever smaller and more inexpensive devices. This article focuses on the technical challenges associated with that migration. Due to limitations in size, battery lifetime, and, ultimately, cost, mapping complex video applications onto resource-constrained systems is a very challenging proposition. To this end, we first consider a technique, region-of-interest (ROI) processing, of defining a window within a video frame and only operating on the data inside that window, ignoring the rest of the frame. By using this lossy technique, the processing requirements can be reduced by roughly 80% while the error introduced in the quality of the results is roughly 10%. The other technique is adaptive data partitioning (ADP) combined with a content-based power management algorithm. By distributing video processing among multiple processors and shutting them down when they are not needed, the energy consumed per processor can be reduced by 60% without sacrificing the performance of the underlying video-based application. Taken together, these novel techniques enable ambient multimedia systems and maintain the needed overall efficiency in video processing.
