Thread shadowing: On the effectiveness of error detection at the hardware thread level

Dynamic thread duplication is a known redundancy technique for multi-cores. Recent research applied this concept to hybrid multi-cores for error detection and introduced thread shadowing that runs hardware threads in the reconfigurable cores and compares their outputs for deviation at configurable signature levels. Previously published work evaluated this concept in terms of performance, error detection latency and resource consumption. In this paper we report on the error detection capabilities of thread shadowing by presenting an extensive fault injection campaign. We employ the Xilinx Soft Error Mitigation Controller for fault injection and the Xilinx Essential Bit facility to limit the fault injections to relevant bits in the configuration bitstream. Our findings from fault injection experiments with a sorting benchmark are threefold: First, up to 98% of all errors are detected by the operating system of the hybrid multi-core supported by thread shadowing. Second, thread shadowing's signature levels provide a useful trade-off between detected errors and effort needed, with around 5% of all errors detected in calls to operating system functions and around 52% of errors detected in memory accesses of the hardware thread. Third, essential bit testing is effective and cuts down the amount of bits to be tested by a factor of 14.48 compared to the total amount of bits available in the configuration address space.
FXa Inhibition and Coagulation Changes During DVT Prophylaxis by Enoxaparin Over the Course of a 15-Day Follow-Up in Septic Patients

The objective of our study was to examine the changes in coagulation parameters and inflammatory reaction over the course of 15 days in patients with severe sepsis. We tried to identify mechanisms by which sepsis-induced pathophysiological changes may influence the effectiveness of subcutaneously (SC) administered enoxaparin 40 mg once daily. A total of 16 patients (8 men, 8 women; age 35-83 years) meeting the inclusion criteria of severe sepsis were enrolled in this study. The follow-up was performed on days 1, 2, 3, 6, 9, 12, and 15 of hospitalization at the intensive care unit (ICU). Blood coagulation (activated partial thromboplastin time [aPTT], prothrombin time [PT], fibrinogen, antithrombin (AT), protein C [PC], D-dimer, fragment 1.2 [F1.2], factor Xa [FXa] inhibition) and inflammatory reactants (interleukin 6 [IL-6], C-reactive protein [CRP], orosomucoid, α-1-antitrypsin) were tested. The mean FXa inhibition was 0.17 (±0.17) IU/mL. The arbitrarily established range of FXa inhibition for prophylaxis, 0.2 to 0.4 IU/mL, was reached in 22 cases (20%), while in 74 cases (68%), it was below and in 13 cases (12%) above the aforementioned range. Factor Xa inhibition positively correlated with AT (r = .42; P < .001) and PC (r = .45; P < .001) activities. A negative correlation was found between the FXa inhibition and α-1-antitrypsin concentrations (r = —.33; P = .01) but only in the subgroup with α-1-antitrypsin concentrations ≥2.2 g/L. We confirmed that in most patients with sepsis, the prophylaxis with enoxaparin did not lead to the required FXa inhibition. The inhibition of FXa by enoxaparin depends mainly on the AT and PC activities.
Social Networks and Reading Behavior in the Blogosphere

This paper describes a comprehensive study on social networks of weblogs integrated with analysis of users’ reading behavior. The analyzed data are obtained from a Japanese weblog hosting service, Doblog. Four kinds of social networks are generated and analyzed: citation, comment, trackback, and blogroll networks. In addition, the user log data are used to identify readership relations among bloggers. After analysis of more than 50,000 users for about two years, we reveal some interactions between social relations and readership relations. We first show that bloggers read other weblogs on a regular basis (50% of weblogs that are read at least three times are read every five times a user logs in). We call this relation a regular reading relation (RR relation). Then, prediction of RR relations is done using features from the four kinds of social networks. Lastly, information diffusion on RR relations is analyzed and characterized. Our findings provide an overview of social relations and reading behavior. The results support those of existing studies of social network analysis on the blogosphere.
Serum biochemical analytes in captive Amazonian manatees (Trichechus inunguis).

BACKGROUND Establishment of reference values for serum biochemical analytes is important for monitoring health and physiological status of captive animals. OBJECTIVE The purpose of this study was to measure and report ranges for serum biochemical analytes in Amazonian manatees (Trichechus inunguis). METHODS Blood samples were collected from 24 healthy captive Amazonian manatees that comprised a mixture of adults, subadults, and calves and males and females; serum analytes were measured and analyzed using a dry reagent bench-top chemical analyzer. Comparisons were made between sexes and with previously published values of closely related species. RESULTS Medians and ranges (minimum-maximum) of values for the analytes were: lactate dehydrogenase (LDH), 151 (111-278) U/L (n=20); creatine kinase, 144 (76-315) U/L (n=11); alanine aminotransferase, 10 (2-28) U/L (n=18); aspartate aminotransferase, 14 (5-28) U/L (n=21); γ-glutamyltransferase, 47 (36-73) U/L (n=21); amylase, 1428 (1010-1874) U/L (n=21); alkaline phosphatase, 73 (36-141) U/L (n=19); total protein, 6.8 (6.2-8.0) g/dL (n=24); albumin, 3.3 (2.6-4.1) g/dL (n=21); cholesterol, 188 (101-399) mg/dL (n=21); triglycerides, 126 (60-236) mg/dL (n=21); glucose, 47 (22-69) mg/dL (n=21); urea, 43 (21-69) mg/dL (n=21); uric acid, 1.1 (0.5-1.8) mg/dL (n=22); creatinine, 2.2 (1.5-3.3) mg/dL (n=22); total bilirubin, 0.2 (0.2-2.0) mg/dL (n=21); calcium, 12.7 (10.2-18.6) mg/dL (n=24); iron, 282 (207-457) μg/dL (n=13); and magnesium, 6.9 (4.3-8.9) mg/dL (n=20). With the exception of LDH, no differences were observed between sexes. CONCLUSIONS The ranges obtained in this study provide important preliminary estimates for concentrations and activities of serum analytes in Amazonian manatees until a larger reference interval study can be conducted.
Olympic Games Competition: Structural Correlates of National Success

Olympic Games; Baron de Coubertin’s turn-of-the-century resurrection of the ancient Greek spectacles. Although supposedly and as reiterated by International Olympic Committee officials (cf. Brundage, 1956: 35) but competitions between individuals, the games are in fact, as is inter-nation sport in general (cf. Heinild, 1966; McIntosh, 1963: 89-93, 188-203; Morton, 1963: esp. 65-103), an arena of intense between-polities contesting. Overall team performances become sources of national pride and shame as countries vie with
What is that?: gesturing to determine device identity

Computing devices can seamlessly recognize one another as they join and leave a wireless network, but users often experience difficulty identifying a desired device from a continuously changing list of devices surrounding them. This paper describes our custom implementation of a stylus and tags that enable users to rapidly identify devices in dynamic environments. Our system utilizes a natural pointing gesture to identify a device, and subsequently transfer data over a wireless network.
A Look Across Four Years at the Disposition Toward Critical Thinking Among Undergraduate Students

This article examines the critical thinking (CT) dispositions, as measured by the California Critical Thinking Disposition Inventory, of students at a four-year, private, liberal arts, comprehensive university. This paper follows up results first published in 1995. The present findings represent another snapshot of CT dispositions among students who participated in 1996 and during the original investigation in 1992. Longitudinal results about students tested as freshman in 1992 and again as seniors in 1996 are presented. Cross sectional results are reported as well. Questions explored include the relationship between the disposition toward critical thinking, as measured by the CCTDI, and students’ major, gender, class level, and grade point average.
UN EQUILIBRIO BAYESIANO DE NASH: COMPETENCIA A LA COURNOT BAJO INFORMACIÓN ASIMÉTRICA Y PRODUCTOS DIFERENCIADOS

Este articulo es un aporte teorico en dos campos de la economia: teoria de juegos y organizacion industrial. Se halla un equilibrio bayesiano de Nash-Cournot cuando dos empresas compiten en cantidades producidas. Una de las empresas tiene informacion completa sobre sus costos y los de su competidora, pero la otra empresa solo conoce los costos propios y le asigna probabilidades a los posibles costos de su competidora. Los bienes producidos por las empresas pueden ser desde completamente homogeneos hasta completamente heterogeneos. El grado de sustitucion de los productos determina los efectos en el equilibrio, tanto de los costos propios como de los costos de la otra empresa en las cantidades de equilibrio. El analisis de estatica comparativa del equilibrio, indica que los costos propios de cada empresa hacen que disminuyan en mayor proporcion las cantidades de equilibrio cuanto mayor sea el grado de sustituibilidad de los productos. Por otro lado, los costos de la otra empresa hacen que aumente en mayor proporcion las cantidades de equilibrio, a medida que los productos son mas homogeneos o sustituibles.
Immigrant Gateways and Hispanic Migration to New Destinations 1

Our understanding of the underlying demographic components of population change in new Hispanic destinations is limited. In this paper, we (1) compare Hispanic migration patterns in traditional settlement areas with new growth in emerging Hispanic destinations; (2) examine the role of immigration vis-à-vis domestic migration in spurring Hispanic population redistribution; and (3) document patterns of migrant selectivity, distinguishing between in-migrants and non-migrant Hispanics at both the origin and destination. We use several recent datasets, including the 1990 and 2000 Public Use Microdata Samples (which include new regional geocodes), and the 2005 and 2006 files of the American Community Survey. Our results document the widespread dispersion of the Hispanic population over the 1990–2006 period from established Hispanic gateways into new Hispanic areas and other parts of the country. Nearly one-half of Hispanic net migration in new destinations comes from domestic gains. In contrast, both established and other Hispanic areas depend entirely on immigration, with each losing domestic migrants to high growth areas. Migrant flows also are highly differentiated by education, citizenship, and nativity. To fully understand the spatial diffusion of Hispanics requires a new appreciation of the complex interplay among immigration, internal domestic migration, and fertility.
Phonological recoding deficit in working memory of dyslexic teenagers

The picture span performance of developmental dyslexic teenagers (mean age 14 years 1 month) was compared to the picture span performance of both RA (mean age 9 years 0 month) and chronological age match controls (mean age 14 years 1 month). Three stimulus lists were manipulated for visual and phonological similarity. Findings indicated that all three groups showed a significant phonological similarity effect but only the dyslexic group showed a significant visual similarity effect. The presence of dual visual-verbal coding is postulated to be responsible for the ‘noisy’ encoding which others (e.g. Johnston and Anderson, 1998; Swan and Goswami, 1997) have suggested is a root cause of dyslexia. The results are discussed in terms of developmental deficits in the central executive of the working memory system.
Breakdown of the blood-brain barrier after fluid percussion brain injury in the rat: Part 2: Effect of hypoxia on permeability to plasma proteins.

Clinical studies have demonstrated that hypoxia after severe brain injury is common and significantly worsens neurologic outcome. We have, therefore, developed a rat model of posttraumatic hypoxic injury in order to identify the pathophysiologic responses after head injury that are worsened by this secondary insult. We examined the effect of hypoxia after brain injury on permeability of the blood-brain barrier to plasma proteins. Animals were divided into two experimental groups: group I (impact alone) and group IH (impact plus hypoxia). Rats were subjected to a lateral fluid percussive brain injury (4.8-5.2 atm). Animals in group IH were exposed to hypoxic conditions (10% O2) for 45 min immediately after injury. In each group, vascular permeability to endogenous immunoglobulins (IgG) and to horseradish peroxidase (HRP) was examined at the light microscopic level. IgG was immunolocalized in brain sections at 1-24 h after injury. In other studies, HRP was given i.v. either before impact or 10 min before killing. Permeability to this protein was assessed at 1-72 h after injury. The distribution of extravasated proteins was similar between the experimental groups at 1 h postinjury. Pronounced abnormal permeability to IgG and HRP (given before impact) occurred in discrete regions throughout both the ipsilateral and contralateral hemispheres. By 6 h after injury, a differential response of the blood-brain barrier was noted between groups I and IH. Widespread leakage of proteins was observed in the injured hemisphere in group IH. This finding was in sharp contrast to group I, in which extravasated proteins remained more localized in the injured hemisphere. The time course for reestablishment of the blood-brain barrier to HRP (given before killing) was determined. The impact site remained permeable to HRP up to at least 72 h postinjury within groups I and IH. In group I, the blood-brain barrier was reestablished in the parasagittal cortex and deep cortical layer by 6 h postinjury. In contrast, the blood-brain barrier in group IH was not restored in similar brain regions until 24 h postinjury. These studies demonstrate that (1) hypoxia after brain injury exacerbates the regional breakdown of the blood-brain barrier to circulating proteins, (2) this influence of hypoxia on permeability is not apparent immediately after injury but rather is expressed at 6 h after injury, and (3) hypoxia after traumatic brain injury delays recovery of the blood-brain barrier. These findings suggest that secondary posttraumatic hypoxia contributes to the vascular pathogenesis of brain injury.

Evaluation and Correction of Cable Phase Stability in High Frequency Near-Field Measurement

In case of the near-field measurement, the radiated field by the measured antenna is received by two- dimensional scanner in defined points. During the process of the field scanning, the cable between the VNA and the scanner antenna is moved and its parameters are changed. This paper deals with the evaluation of the cable parameters changes. The dominant change is represented by the phase deviation of the cable transmission coefficient. The paper also proposes the method of the cable errors correction and evaluation of the correction method efficiency. The correction can be based on the full calibration at the reference plane of the scanner antenna feeding in all points of scanned field. The aforementioned approach is more time consuming than the proposed method, where the full calibration is performed in one selected point, while the correction of the cable parameters is based on the estimation based on the input impedance of the cable loaded by the scanner antenna.
Design and performance analysis of an IEEE 802.15.4 V2P pedestrian protection system

Vulnerable Road User protection systems leveraging V2P (Vehice-to-pedestrian) communications require low-power, low-cost, small size radio communication hardware in order to be suitable for a future mass-market introduction. This paper therefore proposes a Low Power Pedestrian Protection System (LP3S) based on IEEE802.15. 4. It is composed of a retrofit warning unit installed in the vehicle and a miniaturized active Tag-solution with very long battery lifetime to be worn by children, bicycle riders or other endangered persons. A lean protocol design allows for a reliable detection of pedestrians within a critical distance. A comprehensive performance evaluation based on detailed, stochastic system simulation demonstrates the high potential as well as the drawbacks of this solution. The performance indicators focus on the reasonability of alarming messages, with the aim to reduce false alarms to a minimum. Therefore, several solutions for optimizing the warning trigger algorithm are proposed including protocol optimization and incorporation of radio-based distance measurements. The most promising system options are validated in a large-scale simulation containing several hundred vehicles and pedestrians in a realistically modeled environment. The results show a high reasonability for alarming messages inside the vehicle and demonstrate the feasibility and reliability of the proposed pedestrian detection system.
Factors affecting responses of children with autism spectrum disorder to yes/no questions

This study aimed to clarify factors related to difficulties in responding to yes/no questions (Y/N-Qs) among 52 children with autism spectrum disorder (ASD), 41 boys and 11 girls aged between 3:5–16:0 years. Participants completed the Tanaka–Binet Intelligence Scale V, the Picture Vocabulary Test: Revised (PVT-R), and the Pervasive Developmental Disorder – Autism Society Japan Rating Scale (PARS). A yes/no test, developed for this study, included two types of task: a naming true/false task and a request-intention task. For the naming true/false task, clear yes/no responses accounted for 60% of responses among preschool children and more than 90% of responses among school-aged children in the normal IQ and mildly cognitively-impaired groups. In contrast, clear yes/no responses accounted for less than 30% of responses in the moderately cognitively-impaired group, and less than 1% in the severely cognitively-impaired group. For the request-intention task, clear yes/no responses were higher than for naming true/false tasks. Multiple logistic regression analysis indicated that scores of PARS, estimated mental age, vocabulary age according to the PVT-R, and IQ are associated with clear yes/no responses. These findings appear to indicate that ability or inability to respond to Y/N-Qs follows a developmental pattern in children with ASD.
Xylose isomerase improves growth and ethanol production rates from biomass sugars for both Saccharomyces pastorianus and Saccharomyces cerevisiae

The demand for biofuel ethanol made from clean, renewable nonfood sources is growing. Cellulosic biomass, such as switch grass (Panicum virgatum L.), is an alternative feedstock for ethanol production; however, cellulosic feedstock hydrolysates contain high levels of xylose, which needs to be converted to ethanol to meet economic feasibility. In this study, the effects of xylose isomerase on cell growth and ethanol production from biomass sugars representative of switch grass were investigated using low cell density cultures. The lager yeast species Saccharomyces pastorianus was grown with immobilized xylose isomerase in the fermentation step to determine the impact of the glucose and xylose concentrations on the ethanol production rates. Ethanol production rates were improved due to xylose isomerase; however, the positive effect was not due solely to the conversion of xylose to xylulose. Xylose isomerase also has glucose isomerase activity, so to better understand the impact of the xylose isomerase on S. pastorianus, growth and ethanol production were examined in cultures provided fructose as the sole carbon. It was observed that growth and ethanol production rates were higher for the fructose cultures with xylose isomerase even in the absence of xylose. To determine whether the positive effects of xylose isomerase extended to other yeast species, a side‐by‐side comparison of S. pastorianus and Saccharomyces cerevisiae was conducted. These comparisons demonstrated that the xylose isomerase increased ethanol productivity for both the yeast species by increasing the glucose consumption rate. These results suggest that xylose isomerase can contribute to improved ethanol productivity, even without significant xylose conversion. © 2012 American Institute of Chemical Engineers Biotechnol.

Production and perception of contrast: The case of the rise-fall contour in German

This study investigates the phonetics of German nuclear rise-fall contours in relation to contexts that trigger either a contrastive or a non-contrastive interpretation in the answer. A rise-fall contour can be conceived of a tonal sequence of L-H-L. A production study elicited target sentences in contrastive and non-contrastive contexts. The majority of cases realized showed a nuclear rise-fall contour. The acoustic analysis of these contours revealed a significant effect of contrastiveness on the height/alignment of the accent peak as a function of focus context. On the other hand, the height/alignment of the low turning point at the beginning of the rise did not show an effect of contrastiveness. In a series of semantic congruency perception tests participants judged the congruency of congruent and incongruent context-stimulus pairs based on three different sets of stimuli: (i) original data, (ii) manipulation of accent peak, and (iii) manipulation of the leading low. Listeners distinguished nuclear rise-fall contours as a function of focus context (Experiment 1 and 2), however not based on manipulations of the leading low (Experiment 3). The results suggest that the alignment and scaling of the accentual peak are sufficient to license a contrastive interpretation of a nuclear rise-fall contour, leaving the rising part as a phonetic onglide, or as a low tone that does not interact with the contrastivity of the context.
Exploiting the structure of OSTBC's to improve the robustness of worst-case optimization based linear multi-user MIMO receivers

In this paper, we improve the performance of robust linear receivers for multi-user multiple-input multiple-output (MIMO) wireless systems by exploiting the inherent structure of orthogonal space-time block codes (OSTBC). This particular structure results in a worst-case optimization problem with structured uncertainty set. Exploiting this structure, an improved robust linear receiver with a combination of fixed diagonal loading and adaptive non-diagonal loading of the data covariance matrix is obtained.
