Pure Spinor Formalism for Osp(N |4) backgrounds

We start from the Maurer-Cartan (MC) equations of the Osp(N |4) superalgebras satisfied by the left-invariant super-forms realized on supercoset manifolds of the corresponding supergroups and we derive some new pure spinor constraints. They are obtained by ”ghostifying” the MC forms and extending the differential d to a BRST differential. From the superalgebras b G = Osp(N |4) we single out different
Systemic Inflammation (C-Reactive Protein) in Type 2 Diabetic Patients Is Associated With Ambient Air Pollution in Pune City, India

OBJECTIVE To study the association between ambient air pollutants and serum C-reactive protein (CRP) concentration in 1,392 type 2 diabetic patients in Pune, India. RESEARCH DESIGN AND METHODS A cross-sectional study was conducted that linked daily time series of ambient air pollution data (obtained from central monitoring sites) and plasma CRP concentration in type 2 diabetic patients from the Wellcome Trust Genetic (WellGen) Study, recruited between March 2005 and May 2007. Air pollution effects on CRP concentration were investigated with delays (lags) of 0–7 days and multiday averaging spans of 7, 14, and 30 days before blood collection adjusted for age, sex, BMI, hemoglobin, fasting plasma glucose, treatment with agents with anti-inflammatory action, season, air temperature, and relative humidity. RESULTS Median CRP concentration was 3.49 mg/L. For 1 SD increase in SO2 and oxides of nitrogen (NOx) concentrations in ambient air, a day before blood collection (lag1), we observed a significant increase in CRP (9.34 and 7.77%, respectively). The effect was higher with lag2 (12.42% for SO2 and 11.60% for NOx) and wore off progressively thereafter. We also found a significant association with multiday averaging times of up to 30 and 7 days for SO2 and NOx, respectively. No significant associations were found between particulate matter with an aerodynamic profile ≤10 µm (PM10) and CRP concentration except in summer. The association was significantly higher among patients with a shorter duration of diabetes, and in those not on statin and thiazolidinedione treatment. CONCLUSIONS We demonstrate, for the first time, a possible contribution of ambient air pollution to systemic inflammation in Indian type 2 diabetic patients. This may have implications for vascular complications of diabetes.
Co-operative communication with SNR weighted algorithm in cognitive radios

Nowadays wireless networks are regulated by fixed spectrum access policy. But all the fixed assigned spectrums are not utilized fully at all times. At the same time frequency spectrum need has increased drastically as the spectrum is being used for different multimedia applications with voice communication. It gives rise to a need to dynamically access the available frequency spectrum. Cognitive Radio (CR) is the intelligent technology which can sense vacant frequency spectrum i.e. the spectrum not being used by licensed users at the time when CR requires it. So sensing vacant channel is very important in CR technology. Sometimes due to fading and shadowing effects single CR user can't detect the presence of licensed (Primary) user. Co-operative spectrum sensing helps in improving the sensing process and getting more reliable results. Here we are discussing three different co-operative spectrum sensing algorithms with energy detection for local spectrum sensing. We will discuss traditional co-operative spectrum sensing (TCSS), SNR weighted co-operative spectrum sensing (SWCSS) and selective SNR weighted co-operative spectrum sensing (SSWCSS). Simulation shows that SWCSS gives better results than TCSS and the numbers of co-operating secondary users (SU) are reduced and consumption of system resource is minimized. SSWCSS is similar to SWCSS but the number of co-operating secondary users (SU) can be reduced further.
Reasoning Through Race: College Students of Color and the Dynamics of Racial Authority

As racial tensions continue on college campuses across the nation, more attention is needed to understanding the ways in which students of color gain a level of authority in speaking on racial issues. Based on interviews with 31 undergraduate students of color from 2 public research universities on the U.S. West Coast, this study asked participants to reason through the concept of race. Using a constructivist grounded theory methodology along with a lens of self-authorship, the findings suggest participants’ reasoning is influenced by different types of racial authority, or who or what is used to support confidence in claims made regarding what race is and how race matters. The findings inform a model of racial authority, which exists across 2 dimensions (holders and sources of authority) that lead to different outcomes. If students of color do not develop their own level of authority on racial issues, they might defer to so-called experts when reasoning through racial realities.
A comparison of microbial protein synthesis in beef steers fed ad libitum winter ryegrass or fodder beet

Microbial protein synthesis of steers (liveweight 286±9 kg) was compared with diets of ad libitum winter grass and fodder beet with 1 kg DM of lucerne silage. The experimental design was a four-by-two treatment comparison (experiment 1 and 2), using 11 day individual pen trials with total faecal and urinary collection. The trials assessed in vivo digestibility of diets, and diurnal variations in rumen parameters (pH volatile fatty acid, ammonia and urea concentrations) and urine and faeces production and N excretion. Microbial protein production was estimated from purine derivatives determined from total urine collection. Dry matter digestibility, voluntary dry matter intake and microbial protein supply to the steers, and the mean diurnal rumen pH, were higher in the steers fed the fodder-beet treatment than in those fed the winter-grass treatment. Fodder beet supplied almost twice as much microbial protein as winter grass despite a lower crude protein concentration of the diet. Total rumen VFA and ammonia concentrations were lower for the fodder-beet treatment than for winter grass but the rumen urea concentration was higher in the fodder-beet treatment. The observed high microbial protein supply with the fodder beet diets is likely the result of ruminal and extra-ruminal adaptations to greater nitrogen recycling in low dry matter diets of high energy density and low crude protein concentrations.
HIDE: Hybrid Intelligence-based Distance Education

This paper proposes a new concept called hybrid intelligence-based distance education (HIDE). The idea of HIDE is to combine human intelligence and machine intelligence to enhance a large scale teacher-student interaction for the web-based distance education. The long term goal is to achieve unnoticeable merging of human intelligence and machine intelligence to maximally enhance teacher-student interaction in distributed environments. In a HIDE system, teacher-student interaction is assisted by the avatars of the teacher and students. The avatars have the functionality of real-time speech-driven face animation, which provides an effective and eﬃcient solution for large scale “face-to-face” communication The avatars of the teacher possess certain degree of intelligence. They can answer simple questions of the students so that they help reduce the load of the teacher. The avatars of the teacher will direct the questions to the teacher if the questions are beyond their capabilities. The avatars of the teacher also help to monitor the students and collect information for the teacher. The teacher avatar can automatically analyze the teacher-student interaction with respect to the course materials.
T cell recognition of major histocompatibility complex class II complexes with invariant chain processing intermediates

Peptides from the lumenal portion of invariant chain (Ii) spanning residues 80-106 (class II-associated Ii peptide [CLIP]) are found in association with several mouse and human major histocompatibility complex (MHC) class II allelic variants in wild-type and presentation- deficient mutant cells. The ready detection of these complexes suggests that such an intermediate is essential to the MHC class II processing pathway. In this study, we demonstrate that T cells recognize CLIP/MHC class II complexes on the surface of normal and mutant cells in a manner indistinguishable from that of nominal antigenic peptides. Surprisingly, T cell hybrids specific for human CLIP bound to murine MHC class II molecule I-Ab and a new monoclonal antibody 30-2 with the same specificity, recognize two independent epitopes expressed on this peptide/class II complex. T cell recognition is dependent on a Gln residue (position 100) in CLIP, whereas the 30-2 antibody recognizes a Lys residue-at position 90. These two residues flank the 91-99 sequence that is conserved among human, mouse, and rat Ii, potentially representing an MHC class II-binding site. Our results suggest that the COOH-terminal portion of CLIP that includes TCR contact residue Gln 100 binds in the groove of I-Ab molecule. Moreover, both T cells and the antibody recognize I-Ab complexed with larger Ii processing intermediates such as the approximately 12-kD small leupeptin-induced protein (SLIP) fragments. Thus, SLIP fragments contain a CLIP region bound to MHC class II molecule in a conformation identical to that of a free CLIP peptide. Finally, our data suggest that SLIP/MHC class II complexes are precursors of CLIP/MHC class II complexes.
Current–voltage correlations in interferometers

We investigate correlations of current at contacts and voltage fluctuations at voltage probes coupled to interferometers. The results are compared with correlations of current and occupation number fluctuations at dephasing probes. We use a quantum Langevin approach for the average quantities and their fluctuations. For higher order correlations we develop a stochastic path integral approach and find the generating functions of voltage or occupation number fluctuations. We also derive a generating function for the joint distribution of voltage or occupation number at the probe and current fluctuations at a terminal of a conductor. For energy independent scattering we found earlier that the generating function of current cumulants in interferometers with a one-channel dephasing or voltage probe are identical. Nevertheless, the distribution function for voltage and the distribution function for occupation number fluctuations differ, the latter being broader than that of the former in all examples considered here.
TVA: A DoS-Limiting Network Architecture

We motivate the capability approach to network denial-of-service (DoS) attacks, and evaluate the traffic validation architecture (TVA) architecture which builds on capabilities. With our approach, rather than send packets to any destination at any time, senders must first obtain ldquopermission to sendrdquo from the receiver, which provides the permission in the form of capabilities to those senders whose traffic it agrees to accept. The senders then include these capabilities in packets. This enables verification points distributed around the network to check that traffic has been authorized by the receiver and the path in between, and hence to cleanly discard unauthorized traffic. To evaluate this approach, and to understand the detailed operation of capabilities, we developed a network architecture called TVA. TVA addresses a wide range of possible attacks against communication between pairs of hosts, including spoofed packet floods, network and host bottlenecks, and router state exhaustion. We use simulations to show the effectiveness of TVA at limiting DoS floods, and an implementation on Click router to evaluate the computational costs of TVA. We also discuss how to incrementally deploy TVA into practice.
C-reactive protein, interleukin 6, and risk of developing type 2 diabetes mellitus.

CONTEXT Inflammation is hypothesized to play a role in development of type 2 diabetes mellitus (DM); however, clinical data addressing this issue are limited. OBJECTIVE To determine whether elevated levels of the inflammatory markers interleukin 6 (IL-6) and C-reactive protein (CRP) are associated with development of type 2 DM in healthy middle-aged women. DESIGN Prospective, nested case-control study. SETTING The Women's Health Study, an ongoing US primary prevention, randomized clinical trial initiated in 1992. PARTICIPANTS From a nationwide cohort of 27 628 women free of diagnosed DM, cardiovascular disease, and cancer at baseline, 188 women who developed diagnosed DM over a 4-year follow-up period were defined as cases and matched by age and fasting status with 362 disease-free controls. MAIN OUTCOME MEASURES Incidence of confirmed clinically diagnosed type 2 DM by baseline levels of IL-6 and CRP. RESULTS Baseline levels of IL-6 (P<.001) and CRP (P<.001) were significantly higher among cases than among controls. The relative risks of future DM for women in the highest vs lowest quartile of these inflammatory markers were 7.5 for IL-6 (95% confidence interval [CI], 3.7-15.4) and 15.7 for CRP (95% CI, 6.5-37.9). Positive associations persisted after adjustment for body mass index, family history of diabetes, smoking, exercise, use of alcohol, and hormone replacement therapy; multivariate relative risks for the highest vs lowest quartiles were 2.3 for IL-6 (95% CI, 0.9-5.6; P for trend =.07) and 4.2 for CRP (95% CI, 1.5-12.0; P for trend =.001). Similar results were observed in analyses limited to women with a baseline hemoglobin A(1c) of 6.0% or less and after adjustment for fasting insulin level. CONCLUSIONS Elevated levels of CRP and IL-6 predict the development of type 2 DM. These data support a possible role for inflammation in diabetogenesis.
Human hand trajectory analysis in point-and-direct telerobotics

Human hand trajectories have been recorded and analyzed in an experimental supervisory control interface for a telerobot manipulator. Using a six degree-of-freedom tracking device to control the gripper of a computer graphics simulation model of the telerobot, human operators were instructed to command the telerobot under a variety of visual conditions. Analysis of the human hand trajectories shows considerable distortion and adaptation effects in the virtual environments. Also, the nature of the 3D hand trajectories for the reaching task lends support for a sampled-data model of human neurological control; this has design implications for telerobotic interfaces.
A new hybrid audio classification algorithm based on SVM weight factor and Euclidean distance

The text-based classification dominates in the conventional audio classification systems, in which tedious manual work is used to notate the name, class, or sample rate. However, on most occasions, this method is not satisfying due to its opaque to real content. In order to retrieve the audio files effectively and efficiently, content-based audio classification becomes more and more necessary. In this paper, a new hybrid approach of audio classification algorithm is proposed to improve the performance of some misclassified audio data. The proposed method has been compared with the traditional Euclidean-based K-Nearest Neighbor classifier. As to improve the accuracy for specific problems, a weight factor based on Supporting Vector will apply to the Euclidean distance and K-NN rule to achieve better accuracy. The proposed new weighted Euclidean algorithm has been proved to be more sensitive to the classification criteria. The experimental results show that it can improve the audio classification accuracy by 28% at the maximum and 7% in the overall performance. By using the new proposed algorithm, some mis-classified audio data from a conventional Euclidean distance classifier can be classified.
Learned system dynamics for adaptive optimal feedback control

Optimal feedback control (OFC) has been proposed as an attractive movement generation strategy in goal reaching tasks for anthropomorphic manipulator systems. In contrast to classic open loop optimizers that produce “just” a minimal-cost trajectory with implicit resolution of kinematic and dynamic redundancies, the OFC framework additionally yields a feedback control law which corrects errors only if they adversely aect the task performance (minimum
Study on network traffic prediction techniques

We briefly describe a number of traffic predictors (such as ARIMA, FARIMA, ANN and wavelet-based predictors) and analyze their computational complexity. We compare their performance with MSE, NMSE and computational complexity by simulating the predictors on four wireless network traffic traces and decide the most suitable network traffic predictor based on acceptable performance and accuracy.
Performance criteria analysis and further performance results for quasi-orthogonal space-time block codes

Orthogonal space-time block codes (OSTBC) exploits the multiple-input multiple-output (MIMO) communication systems in order to obtain the diversity for high link reliability. Unfortunately, it is not possible to construct an OSTBC with a transmission rate equal to one for more than two transmit antennas. A way to achieve the transmission rates equal to one is to use the quasi-orthogonal STBC (QSTBC). In previous works, it was shown by simulations that the performance of QSTBC can be improved by rotating the constellation of some symbols in the so called transmit matrix. We analyze two different performance criteria proposed in the literature concerning this rotation. We derive an optima with respect to these criteria and show their impact on the bit error rate (BER). Furthermore, we derive some analytical results for the BER-performance.
An approach to intelligently crop and scale video for broadcast applications

Within the scope of the EU-funded project porTiVity (portable interactivity), an application has been developed, that automatically modifies SDTV (Standard Definition Television) sports productions for viewing on mobile TV displays by means of intelligent cropping and scaling. It crops regions of interest of sports productions based on a smart combination of production metadata and systematic video analysis methods. This approach allows a context-based composition for cropped images. It provides a differentiation between the original SD-version of the production and the processed one adapted to the requirements for mobile TV. Envisaged is the integration of the tool in post-production and live workflows.
Linking leader authentic personality to employee voice behaviour: a multilevel mediation model of authentic leadership development

ABSTRACT Drawing on self-consistency and self-concept-based theories, this study examined the antecedents and outcomes of authentic leadership. Specifically, the mediating roles that authentic leadership and organization-based self-esteem (OBSE) play in translating leader authentic personality into employee voice behaviour were investigated. The results, from a sample of 408 subordinate–supervisor dyads from Taiwan, provide evidence of a positive relationship for leader authentic personality with direct reports’ ratings of the leaders’ authentic leadership. In addition, authentic leadership was found to influence subordinates’ voice behaviour, as rated by subordinates’ immediate supervisors; notably, this relationship was partially mediated by the subordinates’ perceptions of OBSE. Furthermore, leader authentic personality was indirectly related to subordinates’ voice behaviour through the mediating influence of authentic leadership and, in turn, subordinates’ perceptions of OBSE. The implications of these results for leadership research and practice, as well as directions for future research, are also presented in this paper.
Haptic rendering of rigid contacts using impulsive and penalty forces

A new simulation approach is proposed to improve the stability and the perceived rigidity of contacts during haptic interaction with multirigid body virtual environments. The approach computes impulsive forces upon contact and penalty and friction forces during contact. The impulsive forces are derived using a new multiple collision resolution method that never increases the kinetic energy of the system. When new contacts arise, the impulsive forces generate large hand accelerations without requiring increased contact stiffness and damping. Virtual objects and linkages are regarded as points in the configuration space, and no distinction is made between them in the proposed approach.

Imaging Live Cells at the Nanometer-Scale with Single-Molecule Microscopy: Obstacles and Achievements in Experiment Optimization for Microbiology

Single-molecule fluorescence microscopy enables biological investigations inside living cells to achieve millisecond- and nanometer-scale resolution. Although single-molecule-based methods are becoming increasingly accessible to non-experts, optimizing new single-molecule experiments can be challenging, in particular when super-resolution imaging and tracking are applied to live cells. In this review, we summarize common obstacles to live-cell single-molecule microscopy and describe the methods we have developed and applied to overcome these challenges in live bacteria. We examine the choice of fluorophore and labeling scheme, approaches to achieving single-molecule levels of fluorescence, considerations for maintaining cell viability, and strategies for detecting single-molecule signals in the presence of noise and sample drift. We also discuss methods for analyzing single-molecule trajectories and the challenges presented by the finite size of a bacterial cell and the curvature of the bacterial membrane.
Asymptotic laws for compositions derived from transformed subordinators

A random composition of n appears when the points of a random closed set R ⊂ [0,1] are used to separate into blocks n points sampled from the uniform distribution. We study the number of parts K n of this composition and other related functionals under the assumption that R = Φ(S • ), where (S t , t ≥ 0) is a subordinator and Φ:[0,∞] → [0, 1] is a diffeomorphism. We derive the asymptotics of K n when the Levy measure of the subordinator is regularly varying at 0 with positive index. Specializing to the case of exponential function Φ(x) = 1 - e -x , we establish a connection between the asymptotics of K n and the exponential functional of the subordinator.
A flying robot with adaptive morphology for multi-modal locomotion

Most existing robots are designed to exploit only one single locomotion mode, such as rolling, walking, flying, swimming, or jumping, which limits their flexibility and adaptability to different environments where specific and different locomotion capabilities could be more effective. Here we introduce the concept and the design of a flying robot with Adaptive Morphology for Multi-Modal Locomotion. We present a prototype that can use its wings to walk on the ground and fly forward. The wings are used as whegs to move on rough terrains. This solution allows to minimize the structural mass of the robot by reusing the same structure (here the wings) for different modes of locomotion. Furthermore, the morphology of the robot is analysed and optimized for ground speed.
