Improving transport design for WARP SDR deployments

Software-Defined radios (SDRs) are a popular platform for developing and implementing wireless protocols. Their basic architecture consists of radio front-ends hosted on an FGPA board, and a back-end processing host for running bulk of the signal processing in software. The two components are bridged, usually by an Ethernet or PCIe interface that transports the radio samples. In addition to the processing delay in software, SDRs may experience a non-negligible transport latency, for example, due to the limited Ethernet bandwidth. Wireless-Access Research Platform (WARP) is one such SDR platform that has recently gained a lot of attention. Research prototypes deploying tens of WARP radios over the Ethernet have become a familiar sight. WARP's transport design, however, is inefficient due to its linear increase in transport latency with the number of radios. We propose modifications to improve the current design. First, we utilize functional parallelism to run the read/write operations of multiple WARP radios concurrently. Second, we propose a high-bandwidth link at the host in order to support the combined transfer rates resulting from the parallel transport to/from the radios. As a result, we achieve a significant reduction in the transport latency by scaling back the linear increase to a constant overhead.
Extensive condyloma acuminata treated with imiquimod 5% cream: a case report

Summary Genital warts are one of the most common sexually transmitted infections, and are caused by human papillomavirus (HPV) types 6 and 11. Standard treatments for genital warts include cryotherapy, laser therapy, trichloroacetic acid and podophyllotoxin. We report the case of a 21‐year‐old female with extensive genital warts. A patient‐applied, non‐destructive therapy was considered to be the most appropriate treatment in this case, due to the extent of the disease and the resulting psychological distress experienced by the patient. She applied imiquimod 5% cream three times per week for a period of 5 weeks, which resulted in complete clearance of all the warts. Minor inflammatory changes were observed during treatment; however, no significant pain was by reported the patient. No recurrences were reported during 2 years of follow‐up.
γδ T Cell Function Varies with the Expressed WC1 Coreceptor 1

WC1 molecules are transmembrane glycoproteins belonging to the scavenger receptor cysteine-rich family and uniquely expressed on γδ T cells. Although participation of WC1+ γδ T cells in immune responses is well established, very little is understood regarding the significance of expressing different forms of the WC1 molecule. Two forms previously identified by mAbs, i.e., WC1.1 and WC1.2, are expressed by largely nonoverlapping subpopulations of γδ T cells. In this study it was shown that expression of the WC1.1 coreceptor was the main indicator of proliferation and IFN-γ production in response to autologous and bacterial Ags as well as for IFN-γ production without proliferation in Th1-polarizing, IL-12-containing cultures. Nevertheless, after culture in either Th1-polarizing or neutral conditions, mRNA was present for both T-bet and GATA-3 as well as for IL-12Rβ2 in WC1.1+ and WC1.2+ subpopulations, and neither produced IL-4 under any conditions. Although the steady decrease in the proportion of WC1.1+ cells, but not WC1.2+ cells, within PBMC with animal aging suggested that the two subpopulations may have different roles in immune regulation, cells bearing either WC1.1 or WC1.2 expressed mRNA for regulatory cytokines IL-10 and TGF-β, with TGF-β being constitutively expressed by ex vivo cells. Overall, the results demonstrate that the form of the WC1 coreceptor expressed on γδ T cells divides them into functional subsets according to IFN-γ production and proliferative capacity to specific stimuli as well as with regard to representation within PBMC. Finally, evidence is provided for minor differences in the intracytoplasmic tail sequences of WC1.1 and WC1.2 that may affect signaling.
Gender openness in managerial education: a sport management focus

Purpose – The purpose of this research paper is to examine the effect of gender openness on female student representation within sport management preparation programs.Design/methodology/approach – A questionnaire was sent to 172 undergraduate and graduate sport management preparation programs within North America and 72 completed surveys were returned. These data were used to test confirmatory factor and structural equation models at the undergraduate (n=47) and graduate levels (n=47). Findings – Results show that gender openness progresses sequentially and is an effect of programmatic size.Research limitations/implications – The primary limitation of this research investigation was the utilization of a cross‐sectional design given the topic sensitivity. Despite its cross‐sectional focus, the study offers important insight about gender openness and inclusion for female students within sport management education.Originality/value – This study utilized a non‐standard approach by examining programs relative t.
Ca2+ nanosparks: shining light on the dyadic cleft but missing the intensity of its signal.

Since the classical, many years ignored, and by current standards haphazard experiments of Sidney Ringer1 on isolated rat hearts, we have come a long way in understanding the role of Ca2+ in the contraction of cardiac muscle. Ringer1 found that suspending the hearts in a saline solution prepared with tap water (which contained high amounts of calcium carbonate from limestone) sustained robust contractions for a long time; but in an attempt to professionalize his art, Ringer1 replaced tap water for distilled water, only to observe that in this clean medium, heart contractions declined quickly after only a few beats. By systematically adding different salts to the distilled saline medium, Ringer1 discovered that calcium, until then considered exclusively a structural element of bones and teeth, was essential for cardiac muscle contraction. Since this serendipitous discovery, many others, in smaller or greater scale, kept adding to the inescapable notion that calcium ions (Ca2+) play a critical role as a relay signal (a messenger) in many biological processes not only of cardiac myocytes, but also of virtually every living cell. Continuing with the story of Ca2+ in the heart, technically challenging experiments by Alexander Fabiato2 defined, almost singlehandedly, the process of Ca2+-induced Ca2+ release in cardiac cells, whereby a small amount of Ca2+ (in his case injected by a microsyringe on skinned cardiac tissue) caused a much larger release of Ca2+ from the sarcoplasmic reticulum (SR), inducing vigorous contractions. Fabiato’s experiments, therefore, set the basis for a functional coupling between the sarcolemma (and its invaginations, the t-tubules) which injected Ca2+ by the voltage-induced opening of L-type Ca2+ channels (dihydropyridine receptors [DHPRs]) and the SR, which elicited massive Ca2+ release on binding of the incoming Ca2+ to …
QoS-Aware Channel Assignment for Weighted Sum-Rate Maximization in D2D Communications

Underlaying device-to-device (D2D) communication links to a cellular network is a promising way to improve spectrum efficiency, for which the cross- link interference should be carefully controlled. Resource allocation has been widely utilized for managing interference in D2D networks. However, most previous works made simple assumptions by either ignoring the reliability requirement of D2D links or not allowing multiple D2D links to share the same channel. In this paper, we propose effective channel assignment algorithms to maximize the weighted sum-rate in a cellular network with underlaying D2D communications, where multiple D2D links are allowed to share the same channel. Meanwhile, the minimum Signal-to- Interference-plus-Noise Ratio (SINR) requirements for both cellular and D2D links are guaranteed. We first provide an optimal algorithm based on dynamic programming (DP) to serve as the performance benchmark, which enjoys much lower complexity compared to exhaustive search. To further reduce complexity, we then propose a cluster-based near-optimal channel assignment algorithm. Simulation results will demonstrate the advantage of allowing multiple D2D links to share the same channel in dense D2D networks, as well as verifying the effectiveness of the proposed algorithms.
On Update Rate-Limiting in BGP

In order to reduce the number of BGP updates that routers need to process, it is common to rate-limit such updates using a timer that specifies the minimum time between two consecutive updates for a given destination prefix. Rate-limiting plays an important role in determining the number of routing updates that are generated after a routing event, and the time it takes before the network converges to a new stable state. Still, there are few guidelines for how rate-limiting timers should be configured in order to achieve the desired convergence properties. This work takes a first step in this direction, by exploring how different rate-limiting implementations and configurations affect the resulting churn level in a live BGP session. Measurements are performed on multiple parallel BGP sessions to a stub AS, configured with and without rate-limiting timers. We find that the daily rate of updates is reduced by two thirds when configuring the timer to the default value recommended by BGP standards. We further investigate different rate-limiting implementations and configurations using the measured BGP update patterns on emulated BGP sessions, and find that increasing the rate-limiting timer gives a logarithmic decrease in churn. Finally, using BGP update traces from RouteViews, we present the first empirical model that quantifies the impact of rate-limiting in terms of churn reduction given the observed arrival pattern of BGP updates.
Le langage des chiffres en politique

Il n’est bien sur nul besoin de rappeler que dans statistique, il y a Etat. On sait le faible apport de l’etymologie a l’etiologie. Il faut donc se demander pourquoi les nombres sont omnipresents dans le discours politique – et donc bien au-dela du discours etatique. Sur ce point, la litterature est abondante, marquee notamment par l’œuvre d’Alain Desrosieres (1993, 2008). Il y a un siecle deja, Max Weber voyait dans une rationalisation croissante de l’action publique une caracteristique maje.
Convergence of Unregularized Online Learning Algorithms

In this paper we study the convergence of online gradient descent algorithms in reproducing kernel Hilbert spaces (RKHSs) without regularization. We establish a sufficient condition and a necessary condition for the convergence of excess generalization errors in expectation. A sufficient condition for the almost sure convergence is also given. With high probability, we provide explicit convergence rates of the excess generalization errors for both averaged iterates and the last iterate, which in turn also imply convergence rates with probability one. To our best knowledge, this is the first high-probability convergence rate for the last iterate of online gradient descent algorithms without strong convexity. Without any boundedness assumptions on iterates, our results are derived by a novel use of two measures of the algorithm's one-step progress, respectively by generalization errors and by distances in RKHSs, where the variances of the involved martingales are cancelled out by the descent property of the algorithm.
COMPENSATION FOR ENVIRONMENTAL DEGRADATION IN AUTOMATIC SPEECH RECOGNITION

The accuracy of speech recognition systems degrades when operated in adverse acoustical environments. This paper reviews various methods by which more detailed mathematical descriptions of the effects of environmental degradation can improve speech recognition accuracy using both “data-driven” and “model-based” compensation strategies. Data-driven methods learn environmental characteristics through direct comparisons of speech recorded in the noisy environment with the same speech recorded under optimal conditions. Model-based methods use a mathematical model of the environment and attempt to use samples of the degraded speech to estimate model parameters. These general approaches to environmental compensation are discussed in terms of recent research in environmental robustness at CMU, and in terms of similar efforts at other sites. These compensation algorithms are evaluated in a series of experiments measuring recognition accuracy for speech from the ARPA Wall Street Journal database that is corrupted by artificially-added noise at various signal-to-noise ratios (SNRs), and in more natural speech recognition tasks.
A multilayer reactive system for robots interacting with children with autism

There is a lack of autonomy on traditional Robot-Assisted Therapy systems interacting with children with autism. To overcome this limitation a supervised autonomous robot controller is being built. In this paper we present a multilayer reactive system within such controller. The goal of this Reactive system is to allow the robot to appropriately react to the child's behavior creating the illusion of being alive.
Emotional Intelligence, Information Elaboration, and Performance: The Moderating Role of Informational Diversity

This article explores the effects of Emotional Intelligence (EI) in a team setting. I theorize that informational diversity will moderate the relationship between team EI and performance. I propose that EI increases the ability of team members to engage each other in information elaboration and that elaboration leads to better performance when teams are informationally diverse. In a laboratory study of 47 teams, EI is positively related to performance in the informationally diverse but not homogeneous condition and that elaboration mediates this moderated relationship. The results speak to the importance of studying EI at the team level and considering its boundary conditions.
Dual-Band Microstrip Filter Using a Multilayer Structure for Wireless Applications at 2.45 and 5.8 GHz

In this paper, a new miniaturized configuration of single-input-single-output (SISO) dual-band bandpass filter operating at ISM 2.45 GHz and UNII 5.8 GHz frequency bands using a multilayer structure this stepped-impedance resonators is presented. A coupling aperture is introduced in a common ground to ensure the coupling between the two resonators located in the upper layer and the lower one. The use of stepped-impedance resonators allows tuning the two bands at desired frequencies. Finally, a design example was fabricated to validate the proposed concept. The insertion loss and return loss at the central frequency are -1.35 dB and -17 dB for 2.45 GHz band, respectively, and, -0.98 dB and -13 dB for the 5.8 GHz band, respectively. There is a good agreement between experimental and full-wave electromagnetic (EM) simulation results.
Continuation and prophylactic treatment of bipolar disorder.

OBJECTIVES To summarize the evidence for efficacy from published literature of biological treatments in the continuation and maintenance phases of bipolar disorder, as well as the recommendations about different treatment options made by the working group within the Bipolar Sub-Committee of the Canadian Network for Mood and Anxiety Treatments (CANMAT). METHODS A review of relevant published literature and proceedings of international conferences was conducted. The quality of evidence was assessed and classified according to the Periodic Health Examination criteria. Treatment recommendations of the working group were based on quality of evidence, a consensus of expert views, and the opinions of psychiatrists and family physicians from across Canada. RESULTS There is overwhelming evidence for the efficacy of lithium in the prophylaxis of bipolar disorder. The evidence for carbamazepine is less robust. There are no published double-blind studies with adequate numbers of subjects treated with divalproex sodium. CONCLUSIONS During and at the end of the continuation phase it is recommended that mood stabilizers should remain the mainstay of therapy and that other treatments should be gradually discontinued or maintained only if there is valid reason to do so. Efficacious maintenance treatment can reduce morbidity and mortality significantly and improve patients' quality of life.
Effects of Wheelchair Sports on Respiratory Muscle Strength and Thoracic Mobility of Individuals with Spinal Cord Injury

Objective The aim of this study was to evaluate the effects of wheelchair sports on respiratory muscle strength and the thoracic mobility of individuals with spinal cord injury. Design Thirty male subjects with chronic spinal cord injury (American Spinal Injury Association Impairment Scale grade A) took part in the study and were divided into four groups: sedentary subjects with quadriplegia (S-QUAD, n = 7), wheelchair rugby athletes with quadriplegia (A-QUAD, n = 8), sedentary subjects with paraplegia (S-PARA, n = 6), and wheelchair basketball athletes with paraplegia (A-PARA, n = 9). The main outcome measures were maximal inspiratory and expiratory pressure and the respiratory coefficients at the axillary and xiphoid levels. Results A-QUAD group presented values significantly higher for all respiratory variables studied compared with the S-QUAD group. No significant differences in any of the respiratory variables were observed between S-PARA and A-PARA groups. There was a negative correlation between spinal cord injury level and respiratory variables for the S-QUAD and S-PARA groups. There were positive correlations in the A-QUAD group between time of training and maximal inspiratory pressure (adjusted R2 = 0.84; P = 0.001) and respiratory coefficients at the axillary level (adjusted R2 = 0.80; P = 0.002). Conclusions Physical training seems to have a positive influence on respiratory muscle strength and thoracic mobility, especially in subjects with quadriplegia.
Improved knowledge management through first-order logic in engineering design ontologies

Abstract This paper presents the use of first-order logic to improve upon currently employed engineering design knowledge management techniques. Specifically, this work uses description logic in unison with Horn logic, to not only guide the knowledge acquisition process but also to offer much needed support in decision making during the engineering design process in a distributed environment. The knowledge management methods introduced are highlighted by the ability to identify modeling knowledge inconsistencies through the recognition of model characteristic limitations, such as those imposed by model idealizations. The adopted implementation languages include the Semantic Web Rule Language, which enables Horn-like rules to be applied to an ontological knowledge base and the Semantic Web's native Web Ontology Language. As part of this work, an ontological tool, OPTEAM, was developed to capture key aspects of the design process through a set of design-related ontologies and to serve as an application platform for facilitating the engineering design process. The design, analysis, and optimization of a classical I-beam problem are presented as a test-bed case study to illustrate the capabilities of these ontologies in OPTEAM. A second, more extensive test-bed example based on an industry-supplied medical device design problem is also introduced. Results indicate that well-defined, networked relationships within an ontological knowledge base can ultimately lead to a refined design process, with guidance provided by the identification of infeasible solutions and the introduction of “best-case” alternatives. These case studies also show how the application of first-order logic to engineering design improves the knowledge acquisition, knowledge management, and knowledge validation processes.
Towards a New Digital Data Infrastructure for Urban Analysis and Modelling

Formal models of urban systems have the potential to reveal a lot about the form and functioning of urban settlements, yet much of this potential has still to be realised. In this paper we focus on the extent to which this has reflected the dearth of digital data that are rich, relevant, and disaggregate. Geodemographic classifications have made important and enduring contributions to small-area analysis. Yet, on the one hand, reliance upon census data makes them outdated and irrelevant and, on the other, fragmentation and diversification of social areas in cities has made the ‘mosaic metaphor’ of small-area analysis untenable. As part of the quest for a new perspective on data modelling, we investigate in this paper the potential of ‘lifestyles’ data sets for creating richer, more relevant digital models of human activity patterns in cities.
Effects of Computer Programming on Young Children's Cognition

Computers will soon be an integral part of the classroom and home environment of children, yet there are unanswered questions concerning their effects on young children's cognition; Particularly salient are largely unsubstantiated claims concerning the cognitive benefits of computer programming. This study assessed the effects of learning computer programming on children's cognitive style (reflectivity, divergent thinking), metacognitive ability, cognitive development (operational competence, general cognitive measures), and ability to describe directions. Eighteen 6-year-old children were pretested to assess receptive vocabulary, impulsivity/reflectivity, and divergent-thinking abilities. The children were then randomly assigned to one of two treatments, computer programming or computer-assisted instruction (CAI), that lasted 12 weeks. Posttesting revealed that the programming group scored significantly higher on measures of reflectivity and on two measures of divergent thinking, whereas the CAI group showed no significant pre- to posttest differences. The programming group outperformed the CAI group on measures of metacognitive ability and ability to describe directions. No differences were found on measures of cognitive development. The increasing acceptance of the critical necessity for children to become computer literate is leading to an increased prominence of computers in the home and school environment. Yet there are unanswered questions regarding the effects of computer use on children's thinking. The purpose of this study was to investigate the effects of computer programming on 6-year:old children's cognitive style, metacognitive abilities, cognitive development, and ability to describe directions. Seymour Papert, one of the creators of the computer language Logo and a leading exponent of the use of computer programming to expand children's intellectual power, based his ideas on the theories of Piaget, with whom he studied. Papert (1980) has argued that the most beneficial learning is what he calls "Piagetian learning," or "learning without being taught. " He has proposed that computer programming environments can create conditions under which intellectual models take root, conditions in which young children can master
