MuZi: Multi-channel ZigBee Networks for Avoiding WiFi Interference

In Cyber-Physical system (CPS), different wireless technologies are used, which results in cross-technology communication interference. Specifically, ZigBee networks share the 2.4GHz ISM band with WiFi but have much lower transmission power. Thus, the ZigBee networks inevitably suffer the interference from WiFi Networks. This paper focuses on the locality of WiFi interference and proposes an interference avoiding approach based on multi-channel for ZigBee networks called MuZi. MuZi has three basic mechanisms: interference assessment, channel switch and connectivity maintenance. The proposed interference assessing approach jointly considers the degree of intensity and density and achieves a much actual relationship between WiFi interference and link quality. Based on this finding, the better working channel for each node is determined. A connectivity maintenance approach is also proposed to ensure the connectivity of the nodes to the sink. Our extensive experiments on a test bed of 802.11 embedded nodes and 802.15. 4 TelosB motes show that, under the existence of WiFi interference, MuZi can achieve 3.3 times throughput than the traditional single-channel method.
LTI Agent Rescue : A Partial Global Approach for the RoboCup Rescue Task Allocation

Coordenação é um dos principais problemas em sistemas multiagentes, além de também desempenhar um papel essencial na gestão de desastres. A alocação de tarefas é uma fase importante do problema de coordenação, já que a decomposição de um objetivo em tarefas é a forma mais natural para se organizar o trabalho entre agentes. Nesse artigo, é proposta uma abordagem híbrida de alocação de tarefas para coordenar os agentes na RoboCup Rescue Agent Simulation, que considera a existência de informações locais e globais. Além disso, é apresentada uma metodologia para a análise comparativa entre times de agentes, que é aplicada na comparação dos resultados obtidos pelo time LTI Agent Rescue, que utiliza a abordagem proposta, com os resultados obtidos por outros times de agentes que implementam abordagens distintas para solucionar o problema da coordenação.

The Impact of Systematic Variation of Cognitive Demand on Drivers' Visual Attention across Multiple Age Groups

Recordings of drivers' gaze under three levels of cognitive demand were captured under actual driving conditions in individuals in their 20's, 40's and 60's. Changes in the allocation of visual attention between single-task driving and the three levels of cognitive secondary tasks are summarized. Under the conditions studied here, gaze centralization varies by task difficulty and appears predominantly in the horizontal plane. The degree of horizontal gaze centralization with added cognitive workload is not related to age in the relatively healthy individuals studied.
A Comparison of Cornell and Sokolow-Lyon Electrocardiographic Criteria for Left Ventricular Hypertrophy in Korean Patients

Background and Objectives Electrocardiography (ECG) is a cost-effective and useful method for diagnosing left ventricular hypertrophy (LVH) in a large-scale study or in clinical practice. Among ECG criteria, the Cornell product (Cor P) and Sokolow-Lyon criteria were adopted by the European Society of Hypertension-European Society of Cardiology Guidelines but have different performances among races. The aim of this study was to compare the diagnostic performance of two voltage criteria in Korean patients. Subjects and Methods Electrocardiography and echocardiographic LV mass of 332 (159 male, 173 female) consecutive patients were analyzed. Cornell voltage criteria and the Cor P were compared with Sokolow-Lyon voltage (Sok V) and the Sokolow-Lyon product (Sok P). The sensitivities and specificities were estimated using a receiver-operating characteristics (ROC) curve in relation to the LVH diagnosis. The sensitivities and revised cut-off values were derived at specificity levels of 90, 95, and 100%. Results The Cornell-based criteria generally showed better performance than that of the Sok V criteria and Sok P in the area under the ROC curve analysis. The revised cut-off values for the Cornell voltage criteria (20 and 16 mm for males and females, respectively) showed an improved sensitivity (19.7 and 30.3% for males and females, respectively), with a high specificity of 95%. Conclusion The Cornell-based criteria had better performance than that of the Sokolow-Lyon criteria in both Korean men and women. However, revised cut-off values are needed to improve accuracy.
Integrative capability, product innovation, and the moderating role of proactiveness and technological environment

Integrative capability refers to a firm's ability to purposefully acquire, combine and deploy resources that are available in business partnerships for achieving managerial visions. Research has yet to explore the benefits of integration in partnerships for different types of product innovation despite the increasingly importance of inter-firm relationships for technology transfer and product innovation. This study proposes that integrative capability has curvilinear and differential effects on explorative and exploitative innovation. Based on multi-soured survey data from 212 Chinese firms, the findings support the proposition that integrative capability has a positive linear effect on exploitative innovation, but an inverted U-shaped relationship with exploration. That is, a high level of integrative capability impedes explorative innovation. The findings also indicate that proactiveness strategy moderates the integrative capability and exploration relationship, mitigating the decline in exploration at a higher level of integrative capability. In addition, under the unique context of emerging economies, technological turbulence enhances the benefits of partnership integration on both explorative and exploitative innovation.
Blood flow of the middle cerebral artery with sleep-disordered breathing: correlation with obstructive hypopneas.

BACKGROUND AND PURPOSE Epidemiological data link heavy snoring to an increased risk for stroke, an association often ascribed to hypertension and/or sleep apnea. The aim of this study was to determine whether obstructive hypopneas, central apneas, or obstructive apneas during sleep alter blood flow of the middle cerebral artery (MCA). METHODS Doppler sonography of the MCA was performed in conjunction with nightly polysomnography in 11 men and one woman. RESULTS A significant decline in blood flow occurred in 76% (169/223) of obstructive hypopneas and in 80% (98/123) of obstructive apneas, compared with only 14% (13/96) of central apneas (P<.0001). While duration of events was not significantly different, MCA blood flow reductions were associated only with the duration of the obstructive hypopneas (P< or =.01) and not with the duration of central (P=.17) or obstructive (P=.07) apneas. The magnitude of fall in arterial oxygen saturation from baseline correlated with a reduced blood flow with obstructive hypopneas but not with obstructive or central apneas. CONCLUSIONS With obstructive hypopneas and obstructive apneas, MCA blood flow is more often decreased in comparison to central apneas. MCA blood flow reductions occur with longer obstructive hypopneas and with those hypopneas with greater falls in oxygen saturation. These observations indicate pathophysiology relevant to an increased risk for stroke in heavy snorers and patients with obstructive hypopneas and apneas.
Psychosocial Factors Associated with Disclosure of HIV Positive Serostatus: Understanding the Influence of Depression and Social Support

ABSTRACT This study examined the relationships of demographic and psychosocial variables to disclosure of HIV infection. HIV-positive adults (n = 156) completed measures assessing depression, perceived satisfaction with social support, and attitudes related to disclosure among their social network. Nearly everyone in this sample (98%) disclosed HIV status to at least one person. Greater depressive symptoms were reported among participants who experienced regret after disclosure. Moreover, the decision never to disclose was associated with less social support satisfaction. These findings suggest that interventions that develop effective serostatus disclosure skills may be efficacious in decreasing psychosocial distress among HIV-positive adults.
First-principles calculations of nonlinear optical susceptibility of inorganic materials

A method for calculations of the frequency-dependent nonlinear susceptibility of inorganic materials is implemented in the velocity gauge using a linear combination of atomic orbitals (LCAO) method within the framework of either the Hartree-Fock approximation or density functional theory. It is based on the standard time-dependent diagrammatic perturbation theory and has previously been applied successfully for atoms and molecules. For inorganic materials, it requires the eigenvalues and position operator matrix elements at several k points in the Brillouin zone. A quantitative assessment of the predictability of the method was made on cubic GaN for which the results of previous theoretical studies are available.
Coagulase expression in Staphylococcus aureus is positively and negatively modulated by an agr-dependent mechanism

Expression of staphylocoagulase by agr+ Staphylococcus aureus depends on the growth phase, being maximal during exponential growth and decreasing sharply postexponentially, while an agr-deleted strain continuously expresses an intermediate level of coagulase. Therefore, coagulase expression appears to be both positively and negatively modulated by an agr-dependent mechanism.
A New Type of Compartment, Defined by Plant-Specific Atg8-Interacting Proteins, Is Induced upon Exposure of Arabidopsis Plants to Carbon Starvation[C][W]

This work describes two new plant-specific proteins, termed ATI1 and ATI2, which bind Atg8f, a central protein of the autophagy machinery. Upon carbon starvation, these proteins are associated with previously undefined spherical bodies that move dynamically on the endoplasmic reticulum network. Atg8 is a central protein in bulk starvation–induced autophagy, but it is also specifically associated with multiple protein targets under various physiological conditions to regulate their selective turnover by the autophagy machinery. Here, we describe two new closely related Arabidopsis thaliana Atg8-interacting proteins (ATI1 and ATI2) that are unique to plants. We show that under favorable growth conditions, ATI1 and ATI2 are partially associated with the endoplasmic reticulum (ER) membrane network, whereas upon exposure to carbon starvation, they become mainly associated with newly identified spherical compartments that dynamically move along the ER network. These compartments are morphologically distinct from previously reported spindle-shaped ER bodies and, in contrast to them, do not contain ER-lumenal markers possessing a C-terminal HDEL sequence. Organelle and autophagosome-specific markers show that the bodies containing ATI1 are distinct from Golgi, mitochondria, peroxisomes, and classical autophagosomes. The final destination of the ATI1 bodies is the central vacuole, indicating that they may operate in selective turnover of specific proteins. ATI1 and ATI2 gene expression is elevated during late seed maturation and desiccation. We further demonstrate that ATI1 overexpression or suppression of both ATI1 and ATI2, respectively, stimulate or inhibit seed germination in the presence of the germination-inhibiting hormone abscisic acid.
Identities and Interactions.

In the authors' own words, the enterprise of this volume is: (1) "to elaborate a theory of human conduct" and (2) "to explain the Who, What, When, and Where of social interaction in terms of this characteristic 'social conflict' in which all a person's acts are 'anticipated, checked, inhibited, or modified by the gestures and intentions of his fellows. ' " The scope of the book is further characterized by a description on the cover that reads "an examination of human associations in everyday life. " The content of the book is presented in nine chapters and an epilogue. The chapters range from considerations such as "The Philosophy of Conduct" to "The Career of a Relationship," and revolve around the various aspects of assuming roles, perceiving the roles of others, and a person's alteration of his own behavior when interacting with others.

Comparative Study of the Dynamics of Follicular Waves in Mares and Women1

Abstract Deviation in growth rates of the follicles of the ovulatory wave begins at the end of a common growth phase and is characterized by continued growth of the developing dominant follicle (F1) and regression of the largest subordinate follicle (F2). Follicle diameters during an interovulatory interval were compared between 30 mares and 30 women, using similar methods for collecting and analyzing data. Follicles were tracked and measured daily by ultrasonography. Diameter at follicle emergence (mares, 13 mm; women, 6 mm) and the required minimal attained diameter for assessment of follicles (mares, 17 mm; women, 8 mm) were chosen to simulate the reported ratio between the two species in mean diameter of F1 at the beginning of deviation (mares, 22.5 mm; women, 10.5 mm). F1 emerged before F2 (P < 0.02) in each species, and the interval between emergence of the two follicles was similar (not significantly different) between species. Growth rate for F1 and F2 during the common growth phase was similar within species, and the percentage of diameter increase was similar between species. Proportionality between species in diameter of F1 at deviation (2.2 times larger for mares than for women) and at maximum preovulatory diameter (2.1 times larger) indicated that relative growth of F1 after deviation was similar between species. A predeviation follicle was identified in 33% of mares and 40% of women and was characterized by growth to a diameter similar to F1 at deviation but with regression beginning an average of 1 day before the beginning of deviation. The incidence of a major anovulatory wave preceding the ovulatory wave was not different between species (combined, 25%). Results indicated that mares and women have comparable follicle interrelationships during the ovulatory wave, including 1) emergence of F1 before F2, 2) similar length of intervals between sequential emergence of follicles within a wave, 3) similar percentage growth of follicles during the common growth phase, and 4) similar relative diameter of F1 from the beginning of deviation to ovulation. Similar follicle dynamics between mares and women indicate the mare may be a useful experimental model for study of folliculogenesis in women, with the advantage of larger follicle size.
Fractional PID controllers tuned by evolutionary algorithms for robot trajectory control

The aim of this paper is to compare the performances of a fractional order proportional integral derivative (FOPID) controller tuned with evolutionary algorithms for robot trajectory control. In order to make this comparison, a 2-degrees-of-freedom planar robot was controlled by a FOPID controller tuned with particle swarm optimization (PSO) and a real coded genetic algorithm (GA). In order to see the effects of the cost functions on the optimum parameters of the FOPID controller, 3 different cost functions were used: the root mean squared error (MRSE), mean absolute error (MAE), and mean minimum fuel and absolute error (MMFAE). In order to compare the performance of PSO and the GA under different conditions and to test the robustness of the FOPID controller tuned with these algorithms, the parameters of the system model and the given trajectory were changed and white noise was added to the system. All of the simulation results for the robot trajectory experiment show that the FOPID controller tuned by PSO has better performance than the FOPID controller tuned by the GA. Furthermore, the results obtained for the FOPID tuned by both PSO and the GA indicate the superiority of the proposed tuning approach for robot trajectory control.
Evaluation of stAPP: a smartphone-based intervention to reduce prolonged sitting among Belgian adults

Excessive uninterrupted sitting, also known as sedentary behavior, has been detrimentally associated with several health outcomes. However, the general population is often unaware of these health risks. Mobile phone technology offers great potential to increase awareness and to initiate behavior change. This study examined the short-term effects of stAPP, a smartphone-based intervention, on prolonged sitting behavior. Fifty-eight participants were randomly assigned to an intervention group (IG, n = 31) or a control group (CG, n = 27). After 1 week of baseline assessment, the IG received stAPP (i.e. smartphone, smartphone app and corresponding motion sensor) and used it during the following week. CG participants were monitored during 2 weeks without receiving stAPP. Total daily sitting time and prolonged sitting bouts (>30 min bouts of sitting) were objectively assessed using activPAL3 inclinometers. Although no significant changes emerged in the CG in any of the sitting parameters, total sitting time (on weekdays; p = 0.032), number of prolonged sitting bouts (>30 min of sitting) [both on week- (p < 0.001) and weekend days (p = 0.008)] and average duration of prolonged sitting bouts [both on week- (p = 0.004) and weekend days (p = 0.029)] decreased significantly in the IG. The stAPP smartphone-based intervention constitutes a promising intervention tool to interrupt and reduce prolonged sitting behavior. Further long-term studies on a larger scale are needed to further explore the effectiveness of a smartphone-based intervention aimed at reducing prolonged sitting behavior.
NOSTOS: A Paper-Based Ubiquitous Computing Healthcare Environment to Support Data Capture and Collaboration

In this paper, we present a new approach to clinical workplace computerization that departs from the window-based user interface paradigm. NOSTOS is an experimental computer-augmented work environment designed to support data capture and teamwork in an emergency room. NOSTOS combines multiple technologies, such as digital pens, walk-up displays, headsets, a smart desk, and sensors to enhance an existing paper-based practice with computer power. The physical interfaces allow clinicians to retain mobile paper-based collaborative routines and still benefit from computer technology. The requirements for the system were elicited from situated workplace studies. We discuss the advantages and disadvantages of augmenting a paper-based clinical work environment.
CloudKon Reloaded with Efficient Monitoring , Bundled Responses , and Dynamic Provisioning

In today's world the emphasis is on distributed systems which plays an important role on achieving good performance , high system utilization and scalability. Task scheduling and execution over large scale, distributed systems plays an important role on achieving good performance and high system utilization. Due to the explosion of parallelism found in today’s hardware, applications need to perform over-decomposition to deliver good performance; this over-decomposition is driving job management systems’ requirements to support applications with a growing number of tasks with finer granularity. Most of today’s state-of-the-art job execution systems have predominantly Master/Slaves architectures, which have inherent limitations, such as scalability issues at extreme scales and single point of failures. On the other hand distributed job management systems are complex, and employ non-trivial load balancing algorithms to maintain good utilization. CloudKon is a distributed job management system that can support distributed HPC and MTC scheduling, running millions of tasks on multiple nodes. CloudKon, a compact, light-weight, scalable, and distributed task execution framework (CloudKon) that builds upon cloud computing building blocks (Amazon EC2, SQS, and DynamoDB) has been developed to support high performance , high system utilization and scalability, however with some challenges and drawbacks. The downsides lie in Worker-Client communication, Monitoring system causing communication overhead and resource contention respectively. This may prove to be a potential bottleneck at higher scalable systems. The goal in this project is to reload or extend existing CloudKon with features like 1. Improved Concurrency 2. Bundled Response 3. Efficient Monitoring to address the existing challenges in CloudKon as well as implementation of dynamic provisioning.
Voice source estimation for artificial bandwidth extension of telephone speech

Artificial bandwidth extension (ABWE) of speech signals aims to estimate wideband speech (50 Hz – 7 kHz) from narrowband signals (300 Hz – 3.4 kHz). Applying the source-filter model of speech, many existing algorithms estimate vocal tract filter parameters independently of the source signal. However, many current methods for extending the narrowband voice source signal are limited to straightforward signal processing techniques which are only effective for high-band estimation. This paper presents a method for ABWE that employs novel data-driven modelling and an existing spectral mirroring technique to estimate the wideband source signal in both the high and low extension bands. A state-of-the-art Hidden Markov Model-based estimator evaluates the temporal and spectral envelopes in the missing frequency bands, with which the ABWE speech signal is synthesized. Informal listening tests comparing two existing source estimation techniques and two permutations of the proposed approach show an improvement in the perceived bandwidth of speech signals, in particular towards low frequencies. Subjective tests on the same data show a preference for the proposed techniques over the existing methods under test.
