A Time-Interleaved Track & hold in 0.13 μm CMOS sub-sampling a 4 GHz signal with 43 dB SNDR

A 16-channel time-interleaved track and hold is presented. Three techniques are introduced enabling a high bandwidth and linearity and good timing alignment. Integrated ADCs are used to evaluate the performance of the T/H. Single channel performance is 43 dB SNDR at an input frequency of 4 GHz. Multi-channel performance is 48 dB SNDR at 1.35 GS/s with an ERBW of 1 GHz. The power consumption of the T/H including clock-driver and buffers is 74 mW.
Lattice dynamics and elastic properties of corundum by the self-consistent atomic deformation method

We apply a recently developed density-functional method based on localized densities to study electronic, structural, elastic, optical, and vibrational properties of $\ensuremath{\alpha}\ensuremath{-}{\mathrm{Al}}_{2}{\mathrm{O}}_{3}. $ Although our approach is generally less accurate than conventional band-structure methods, calculation of polarization, and related properties is greatly simplified and our results are in reasonably good agreement with experiment and other theoretical calculations. We also assign the symmetry of zone center and other high-symmetry phonon modes and calculate the variation of the zone-center mode frequencies as a function of wave vector direction.
The Relationship between Social Distance and Treatment Attrition for Juvenile Offenders

ABSTRACT: Although recent work has begun to identify factors associated with risk of treatment attrition for juvenile offenders, few of these studies have considered how community context is related to the completion of juvenile offender treatment. The current work examines the relationship between social distance and treatment attrition for juvenile offenders. Analyzing a data set of 5,517 juvenile offenders adjudicated in Philadelphia, the results of cross-classified hierarchical models indicate that social distance, operationalized in two ways that consider perceptions of both the ethnic composition and level of disadvantage within neighborhoods, does not directly predict the likelihood of treatment attrition. However, when considered with the ethnicity of the juvenile offenders in the form of an interaction effect, social distance based on perceptions of ethnicity within neighborhoods is shown to predict the likelihood of treatment attrition, and to be more acute for young non-White offenders. The implications of these findings are discussed.
Traffic patten based resource allocation algorithm for hybrid transmission in LTE networks

Long Term Evolution (LTE) is a new bearer service for 4G that greatly improves and simplifies wireless access to packet data transfer. The purpose of the LTE is to efficiently accommodate data users which are busty in nature. A key challenge of incorporating voice traffic into networks with efficiency guarantees lies in the difficulty of releasing the available communication resource when the channels are not used in the transmission process. A new scheme called traffic pattern based resource allocation scheme consisting of three algorithms is proposed for the integration of voice and data transmission based on the Markovian decision process (MDP). The scheme adaptively releases reserved channels of the data terminals according to traffic pattern under the constraint of capability and call blocking probability. Therefore, it provides efficient performance thereby leading to overall improvement compared with the original allocation system without sacrificing the data capacity of the system.
Anticoccidial vaccines for broiler chickens: Pathways to success

The use of live vaccines, either attenuated or non-attenuated, for the control of coccidiosis due to Eimeria infections in broiler breeder or layer chickens is well established. Use in broilers, however, has been slow to gain acceptance. This has been partly for economic reasons, but also because of perceived adverse effects on early chick growth, particularly with non-attenuated vaccines, and concerns about timely onset of protective immunity in such short-lived birds. This review describes advances in understanding of epidemiological factors and recent improvements of administration methods that have helped to allay these fears and to make the use of anticoccidial vaccines in broilers technically achievable. Topics discussed include: (1) types of commercially available vaccine, (2) vaccines in development, (3) vaccination methods and equipment, (4) basis of vaccine efficacy and immunogenic variation of parasites, (5) key factors in the survival, sporulation and dissemination of vaccinal oocysts, (6) descriptions and significance of patterns of litter oocyst accumulation and occurrence of intestinal lesions in vaccinated flocks, (7) rotation of anticoccidial vaccination and chemotherapy to restore drug sensitivity to resistant wild-type coccidia, (8) combinations of anticoccidial vaccination and chemotherapy, (9) interactions between coccidiosis and clostridiosis in broilers and compatibilities of potential control methods, (10) published performance data for live anticoccidial vaccines in broilers, (11) possible further developments of live vaccines.
Retrieving spoken documents by combining multiple index sources

This paper presents domain-independent methods of spoken document retrieval. Both a continuous-speech large vocabulary recognition system, and a phone-lattice word spotter, are used to locate index units within an experimental corpus of voice messages. Possible index terms are nearly unconstrained; terms not in a 20,000 word recognition system vocabulary can be identified by the word spotter at search time. Though either system alone can yield respectable retrieval performance, the two methods are complementary and work best in combination. Different ways of combining them are investigated, and it is shown that the best of these can increase retrieval average precision for a speakerindependent retrieval system to 85% of that achieved for full-text transcriptions of the test documents.

N-(2,6-Dimethylphenyl)-N′-propanoylthiourea

In the title compound, C12H16N2OS, an intramolecular N—H⋯O hydrogen bond forms an S(6) ring motif. The propionylthiourea group is approximately planar [with a maximum deviation of 0.135 (2) Å] and forms a dihedral angle of 83.39 (7)° with the benzene ring. In the crystal, molecules are linked by pairs of N—H⋯S hydrogen bonds, forming centrosymmetric dimers and generating R 2 2(8) ring motifs.
Ieee Transactions on Visualization and Computer Graphics Attention and Visual Memory in Visualization and Computer Graphics

—A fundamental goal of visualization is to produce images of data that support visual analysis, exploration, and discovery of novel insights. An important consideration during visualization design is the role of human visual perception. How we " see " details in an image can directly impact a viewer's efÀciency and effectiveness. This article surveys research on attention and visual perception, with a speciÀc focus on results that have direct relevance to visualization and visual analytics. We discuss theories of low-level visual perception, then show how these Àndings form a foundation for more recent work on visual memory and visual attention. We conclude with a brief overview of how knowledge of visual attention and visual memory is being applied in visualization and graphics. We also discuss how challenges in visualization are motivating research in psychophysics.
THE PERCEPTION OF POLITICIANS AND POLITICAL ISSUES : A MULTIDIMENSIONAL SCALING APPROACH.

The multidimensional scaling (MDS) of both attitude statements and political candidates in the same multidimensional space was considered to have several ramifications. First, the position of the attitude statements would explicate the nature of the factorial structure of politicians; second, the underlying dimensions would demonstrate whether candidates are perceived in terms of relevant political dimensions. Third, the scaling would reveal the extent of individual differences, especially those based on political affiliation; and last, as a descriptive tool the scaling is of interest in its own right. One hundred fifteen subjects were recruited from various sources, including local campus political clubs. Tucker's (1972) three-mode model of MDS was used to analyze the similarity judgments of these subjects. Results indicated that politicians are perceived in terms of the relevant issues, and that Republicans and Democrats differ markedly in their perception of the political arena. The present experimental paradigm was suggested as a potentially useful method for a number of research problems.
Indoor wireless communications with multiple antennas and polarizations: From channel characterization to performance simulation

In this paper, we describe experimental results characterizing the frequency/space/polarization selectivity of indoor channels at 1.9 GHz. Regarding the delay-angle dispersion, a clustered geometry-based model is developed from measurement results and validated. Regarding dual-polarized channels, a simple analytical model is extracted from experimental data, accounting for the cross-correlation between the various parameters. Finally, narrowband dual-polarized and single-polarized transmissions are compared in real-world indoor channels based on performance metrics for multiplexing and diversity gains.
Random Coattention Forest for Question Answering

We build a Random Coattention Forest Network that achieved 55% F1 score and 41% EM score on the on-line test set of question answering dataset SQuAD. We use Coattention encoder and LSTM Classification decoder to build our basic encoder-decoder pair. Multiple loosely correlated encoder-decoder pairs are trained in parallel to form a random-forest-style model. Our implementation provides efficiency in training, which allowed us to train multiple encoder-decoder pairs and run multiple experiments to tune hyperparameters.
Pacing characteristics of international Sprint Kayak athletes

This study aimed to profile pacing strategies and pacing profile of world-class kayakers during world championships. Data were from publically available websites of eight international competitive seasons (2004 - 2011). Data represent percentage average race pace. Mixed ANOVA was used to compare pacing (250 m splits) and race level (A and B-finals) and crew boats. Effect size was calculated converting F-values into r-values (P < 0.05). There were significant interactions between splits and season (F7.99, 255.7=13.08, P <0.001, r=0.05), splits and boat crew (F5.33, 255.7=4.82, P <0.001, r=0.02), race level, the split speed and the competitive season (F8.49, 271.5=2.07, P =0.035, r=0.01) and the race level, the split speed and the boat crews (F5.66, 271.5=2.28, P =0.04, r=0.01) for the 1000 m. There was a significant interaction between race level, split speed and boat crew (F1, 80=4.35, P =0.004, r=0.05) in the 500 m. Performances of A and B-finals were significantly different. In conclusion, pacing of sprint kayakers can vary according to race level (A or B-finals, elite or sub-elite respectively), crew (K1, K2 and K4), split distances (250 m splits) and competitive seasons. Additionally, our data suggests there may exist specific crew boat dynamics and, therefore, specific race demands.
Stereo parallel tracking and mapping for robot localization

This paper describes a visual SLAM system based on stereo cameras and focused on real-time localization for mobile robots. To achieve this, it heavily exploits the parallel nature of the SLAM problem, separating the time-constrained pose estimation from less pressing matters such as map building and refinement tasks. On the other hand, the stereo setting allows to reconstruct a metric 3D map for each frame of stereo images, improving the accuracy of the mapping process with respect to monocular SLAM and avoiding the well-known bootstrapping problem. Also, the real scale of the environment is an essential feature for robots which have to interact with their surrounding workspace. A series of experiments, on-line on a robot as well as off-line with public datasets, are performed to validate the accuracy and real-time performance of the developed method.
A Landmark Aware Content Searching Scheme in Opportunistic Networks

The spacial distribution of nodes in the Opportunistic networks is uneven in the real scenarios. There are some landmarks with high node density distributed in the network area. Based on the uneven distribution character of nodes in the Opportunistic Networks, a landmark aware content searching scheme (LACS) is proposed. The scheme proposed here is composed of two sub-schemes, latent spray scheme in the home landmark and searching message infection scheme between landmarks, both of which control the searching message carrier amount in the landmarks, and then control the latency of content searching. The simulation results show that the content searching scheme proposed in this paper outperforms the other schemes by 10% in hit ratio and by 5% in latency of content searching.
Combination of immunosuppressive drugs leaves specific “fingerprint” on gene expression in vitro

Following organ transplantation many patients suffer from drug-related side effects, or receive more immunosuppression than necessary to prevent rejection. Hence, parameters are needed to tailor the immunosuppressive therapy to the individual needs of an organ recipient. The aim of this study was to determine whether drug combinations provoke specific gene expression patterns in a simple assay system in vitro. Stimulated peripheral blood lymphocytes were cultured in the presence of cyclosporine A, tacrolimus, mycophenolic acid, everolimus and sirolimus, or combinations thereof. Using a cDNA microarray, we found that all samples clustered in drug-specific groups. Gene expression profiles were almost identical in PBL treated with either cyclosporine A or tacrolimus, and with either sirolimus or everolimus. More than 50 genes were synergistically affected by combinations of calcineurin-inhibitors and TOR-inhibitors and drug-specific regulated genes could be identified for both substance groups. Our data suggest that in vitro gene profiling can be used to describe synergistic effects of immunosuppressive drugs. Furthermore, our approach may help to identify marker genes urgently needed to optimize and individualize immunosuppressive drug regimens after organ transplantation.
Midbrain control of micturition in the rat

The role of the periaqueductal grey (PAG) in the central control of micturition was investigated in urethane-anaesthetised rats, with the aims of furthering understanding of the central control of micturition and identifying novel therapeutic targets for urinary incontinence. Experiments using microinjection of GABAA agonists and antagonists into the midbrain showed that transmission through a localised region of the caudal ventrolateral PAG (cvlatPAG) is critical for reflex voiding and the micturition pathway is normally subject to tonic inhibitory GABAergic control. Experiments to determine the role of dopamine in controlling micturition by selectively lesioning dopamine-containing neurons in the cvlatPAG and microinjection of dopamine agonists and antagonists were inconclusive and require further work. Micturition could however be suppressed completely by trains of electrical stimulation applied throughout the midbrain. Microinjection of an excitatory amino acid over the same area reduced the frequency of micturition without disrupting the pattern of voiding. Though further work is required to determine the mechanism by which electrical stimulation inhibits reflex micturition, collaboration with clinical colleagues has indicated the exciting translational potential of electrical stimulation of the midbrain in human patients to treat urinary disturbances that have proven refractory to pharmacotherapy.
Dana36: A Multi-camera Image Dataset for Object Identification in Surveillance Scenarios

We present a novel dataset for evaluation of object matching and recognition methods in surveillance scenarios. Dataset consists of more than 23,000 images, depicting 15 persons and nine vehicles. A ground truth data - the identity of each person or vehicle - is provided, along with the coordinates of the bounding box in the full camera image. The dataset was acquired from 36 stationary camera views using a variety of surveillance cameras with resolutions ranging from standard VGA to three megapixel. 27 cameras observed the persons and vehicles in an outdoor environment, while the remaining nine observed the same persons indoors. The activity of persons was planned in advance, they drive the cars to the parking lot, exit the cars and walk around the building, through the main entrance, and up the stairs, towards the first floor of the building. The intended use of the dataset is performance evaluation of computer vision methods that aim to (re)identify people and objects from many different viewpoints in different environments and under variable conditions. Due to variety of camera locations, vantage points and resolutions, the dataset provides means to adjust the difficulty of the identification task in a controlled and documented manner. An interface for easy use of dataset within Matlab is provided as well, and the data is complemented by baseline results using a basic color histogram-based descriptor. While the cropped images of persons and vehicles represent the primary data in our dataset, we also provide full-frame images and a set of tracklets for each object as a courtesy to the dataset users.
Impedance Spectroscopic Investigation of Proton Conductivity in Nafion Using Transient Electrochemical Atomic Force Microscopy (AFM)

Spatially resolved impedance spectroscopy of a Nafion polyelectrolyte membrane is performed employing a conductive and Pt-coated tip of an atomic force microscope as a point-like contact and electrode. The experiment is conducted by perturbing the system by a rectangular voltage step and measuring the incurred current, followed by Fourier transformation and plotting the impedance against the frequency in a conventional Bode diagram. To test the potential and limitations of this novel method, we present a feasibility study using an identical hydrogen atmosphere at a well-defined relative humidity on both sides of the membrane. It is demonstrated that good quality impedance spectra are obtained in a frequency range of 0.2–1000 Hz. The extracted polarization curves exhibit a maximum current which cannot be explained by typical diffusion effects. Simulation based on equivalent circuits requires a Nernst element for restricted diffusion in the membrane which suggests that this effect is based on the potential dependence of the electrolyte resistance in the high overpotential region.
Atmospheric Chemistry and Physics Primary and Secondary Organic Carbon Downwind of Mexico City

In order to study particulate matter transport and transformation in the Megacity environment, fine particulate carbon was measured simultaneously at two supersites, suburban T1 and rural T2, downwind of Mexico City during the MILAGRO field campaign in March 2006. Organic carbon (OC), element carbon (EC), and total carbon (TC=OC+EC) were determined in near real-time using a Sunset semi-continuous OCEC field analyzer. The semi-empirical EC tracer method was used to derive primary organic carbon (POC) and secondary organic carbon (SOC). Diurnal variations of primary and secondary carbon were observed at T1 and T2, which resulted from boundary layer inversion and impacted by local traffic patterns. The majority of organic carbon particles at T1 and T2 were secondary.
Acceleration techniques for GPU-based volume rendering

Nowadays, direct volume rendering via 3D textures has positioned itself as an efficient tool for the display and visual analysis of volumetric scalar fields. It is commonly accepted, that for reasonably sized data sets appropriate quality at interactive rates can be achieved by means of this technique. However, despite these benefits one important issue has received little attention throughout the ongoing discussion of texture based volume rendering: the integration of acceleration techniques to reduce per-fragment operations. In this paper, we address the integration of early ray termination and empty-space skipping into texture based volume rendering on graphical processing units (GPU). Therefore, we describe volume ray-casting on programmable graphics hardware as an alternative to object-order approaches. We exploit the early z-test to terminate fragment processing once sufficient opacity has been accumulated, and to skip empty space along the rays of sight. We demonstrate performance gains up to a factor of 3 for typical renditions of volumetric data sets on the ATI 9700 graphics card.
Novel Neuronal Phenotypes from Neural Progenitor Cells

We report the first isolation of progenitor cells from the hypothalamus, a derivative of the embryonic basal plate that does not exhibit neurogenesis postnatally. Neurons derived from hypothalamic progenitor cells were compared with those derived from progenitor cultures of hippocampus, an embryonic alar plate derivative that continues to support neurogenesis in vivo into adulthood. Aside from their different embryonic origins and their different neurogenic potential in vivo, these brain regions were chosen because they are populated with cells of three different categories: Category I cells are generated in both hippocampus and hypothalamus, Category II cells are generated in the hypothalamus but are absent from the hippocampus, and Category III is a cell type generated in the olfactory placode that migrates into the hypothalamus during development. Stem-like cells isolated from other brain regions, with the ability to generate neurons and glia, produce neurons of several phenotypes including gabaergic, dopaminergic, and cholinergic lineages. In the present study, we extended our observations into neuroendocrine phenotypes. The cultured neural precursors from 7-week-old rat hypothalamus readily generated neuropeptide-expressing neurons. Hippocampal and hypothalamic progenitor cultures converged to indistinguishable populations and produced neurons of all three categories, confirming that even short-term culture confers or selects for immature progenitors with enough plasticity to elaborate neuronal phenotypes usually inhibited in vivo by the local microenvironment. The range of phenotypes generated from neuronal precursors in vitro now includes the peptides found in the neuroendocrine system: corticotropin-releasing hormone, growth hormone-releasing hormone, gonadotropin-releasing hormone, oxytocin, somatostatin, thyrotropin-releasing hormone, and vasopressin.
