iRMW: A low-cost technique to reduce NBTI-dependent parametric failures in L1 data caches

Negative bias temperature instability (NBTI) is a major cause of concern for chip designers because of its inherent ability to drastically reduce silicon reliability over the lifetime of the processor. Coupled with statistical variations of process parameters, it can potentially render systems dysfunctional in certain scenarios. Data caches suffer the most from such phenomenon because of the unbalanced duty cycle ratio of SRAM cells and maximum intrinsic susceptibility to process variations. In this paper, we propose a novel NBTI-aware technique, invert-Read-Modify-Write (iRMW) that can improve the functional yield of the data cache significantly over its lifetime. Using architecture-level benchmarks, we first analyse the impact of activity factor and workload variation on NBTI-induced failures in data caches. iRMW is then used as a means to balance the duty cycle by alternating between recovery and stress cycle upon successive read accesses to the cache line. The highly transient nature of the data stored in L1 data cache aides this process of recovery upon using iRMW. A unique feature of iRMW is its intelligent use of low-leakage & NBTI-tolerant embedded-DRAM cells as an alternative to SRAM-cells for storing important state information. Our experiments conducted using SPEC2006 and PhysicsBench workloads show that on-average the cache failure probability can be reduced by 22%, 33% and 36% after two, four and eight years of processor usage respectively. In addition to being extremely power-frugal, use of eDRAM reduces total area footprint of iRMW tremendously.
Dmesh: Fast Depth-Image Meshing And Warping

In this paper we present a novel and efficient depth-image representation and warping technique called DMesh which is based on a piece-wise linear approximation of the depth-image as a textured and simplified triangle mesh. We describe the application of a hierarchical multiresolution triangulation method to generate adaptively triangulated depth-meshes efficiently from reference depth-images, discuss depth-mesh segmentation methods to avoid occlusion artifacts and propose a new hardware accelerated depth-image rendering technique that supports per-pixel weighted blending of multiple depth-images in real-time. Applications of our technique include image-based object representations and the use of depth-images in large scale walk-through visualization systems.

Abstract Evaluating and comparing modelling languages is a prerequisite for progress in the field of conceptual modelling. However, only little research has been dedicated to the investigation of appropriate evaluation methods. It is common practice that mainly those who design modelling language decide about the relevance of particular features. In this paper, we argue that such an approach does not satisfy common academic standards. The quality of a modelling language depends on a variety of tasks and potential users, some of which are beyond the scope of language designers. Therefore, the evaluation of modelling languages requires a cross-disciplinary approach. Furthermore, it has to be taken into account that the analysis of a language imposes severe epistemological problems. Against this background, we introduce a meta-framework for the evaluation of modelling languages. It includes a conceptual model to guide and structure multi-perspective evaluations.
Cpoda - a demand assignment protocol for satnet

A new contention-based demand assignment protocol (CPODA) is described. The protocol is designed to handle packetized data and voice traffic in a multiple access satellite broadcast channel, where the channel is typically shared by hundreds of earth stations. A sophisticated traffic environment is assumed, including multiple priority and delay class distinctions, variable message lengths, and an arbitrary load distribution among the stations. In addition, stations may have different receiving rate capabilities. The CPODA protocol is part of a broader research project concerned with developing protocols for a one-hop satellite network (SATNET). The CPODA and other protocols are currently undergoing experimental evaluation using an INTELSAT IV-A satellite and four earth stations in the Atlantic region.
The Utilization of a New Immunochromatographic Test in Detection of Helicobacter pylori Antibody from Maternal and Umbilical Cord Serum

Background. Helicobacter pylori (H. pylori) was linked with several extragastrointestinal diseases, including preeclampsia and intrauterine growth restriction of fetus. One of the signals which can be transferred from mother to fetus is the H. pylori IgG antibody. Aims. We utilized a commercial immunochromatographic kit to detect the antibody in maternal and cord serum. Methods. Three hundred and forty-six females were enrolled and the blood samples were collected on antenatal examination and on delivery. The maternal H. pylori infection was determined by stool H. pylori antigen test. Results. One hundred and five females (30.3%) were H. pylori-infected, and the prevalence was higher in immigrants (43.5%) than in Taiwanese (28.7%, P = 0.058). The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the kit were 77.1%, 88.0%, 73.6%, 89.8%, and 84.7%, respectively. This kit also had similar performance in cord serum. Comparing to the maternal result on delivery, this kit offered a consistent performance in antenatal maternal serum (kappa coefficient 0.92) and in cord serum (kappa coefficient 0.88). Conclusions. H. pylori IgG antibody can be transferred through the placenta into the fetal circulation. However, accuracy of the test kit needs to be evaluated before utilization in screening.
Digitized by the Internet Archive in 2011 with Funding from a First Pass. the Joint Design of Unemployment Insurance and Employment Protection. a First Pass.*

Unemployment insurance and employment protection are typically discussed and studied in isolation. In this paper, we argue that they are tightly linked, and we focus on their joint optimal design. We start our analysis with a simple benchmark, with risk averse workers, risk neutral firms, and random shocks to productivity. In this benchmark, we show that unemployment insurance comes with employment protection—in the form of layoff taxes; indeed, optimality requires that layoff taxes be equal to unemployment benefits. We then explore the implications of four broad categories of deviations: limits on insurance, limits on layoff taxes, ex-post wage bargaining, and ex-ante heterogeneity of firms or workers. We show how the design must be modified in each case. The scope for insurance may be more limited than in the benchmark; so may the scope for employment protection. The general principle remains however, namely the need to look at unemployment insurance and employment protection together, rather than in isolation. Tsyvinski for helpful comments.
Image Scrambling Algorithm Based on Chaos Theory and Sorting Transformation

†Summary This paper proposed a novel image scrambling scheme based on chaos theory and the sorting transformation. The new algorithm calculates the permuting address codes by sorting the chaotic sequence, not like common method by quantizing the chaotic sequence. Therefore, the new scheme does not require knowing the probability density function of the chaotic orbits in advance, thus not only facilitating the choice of chaotic systems but also reducing the complexity of the scheme. The paper also analyzed the scrambling performance of the new algorithm statistically. The results indicate that the new algorithm can provide a high level security owing to the strong irregularity of sorting transformation.
A Study of Dielectric Properties of Proteinuria between 0.2 GHz and 50 GHz

This paper investigates the dielectric properties of urine in normal subjects and subjects with chronic kidney disease (CKD) at microwave frequency of between 0.2 GHz and 50 GHz. The measurements were conducted using an open-ended coaxial probe at room temperature (25°C), at 30°C and at human body temperature (37°C). There were statistically significant differences in the dielectric properties of the CKD subjects compared to those of the normal subjects. Statistically significant differences in dielectric properties were observed across the temperatures for normal subjects and CKD subjects. Pearson correlation test showed the significant correlation between proteinuria and dielectric properties. The experimental data closely matched the single-pole Debye model. The relaxation dispersion and relaxation time increased with the proteinuria level, while decreasing with the temperature. As for static conductivity, it increased with proteinuria level and temperature.
Magnetorotational Instability in Protoplanetary Disks. II. Ionization State and Unstable Regions

We investigate where magnetorotational instability operates in protoplanetary disks, which can cause angular momentum transport in the disks. We investigate the spatial distribution of various charged particles and the unstable regions for a variety of models for protoplanetary disks, taking into account the recombination of ions and electrons at grain surfaces, which is an important process in most parts of the disks. We find that for all the models there is an inner region that is magnetorotationally stable due to ohmic dissipation. This must make the accretion onto the central star nonsteady. For the model of the minimum-mass solar nebula, the critical radius, inside of which the disk is stable, is about 20 AU, and the mass accretion rate just outside the critical radius is 10-7-10-6 M☉ yr-1. The stable region is smaller in a disk of lower column density. Dust grains in protoplanetary disks may grow by mutual sticking and may sediment toward the midplane of the disks. We find that the stable region shrinks as the grain size increases or the sedimentation proceeds. Therefore, in the late evolutionary stages, protoplanetary disks can be magnetorotationally unstable even in the inner regions.
An efficient document classification algorithm based on kernel LDE

To efficiently deal with document classification problem, an efficient document classification algorithm based on kernel local discriminant embedding(kernel LDE) is proposed in this paper. The high-dimensional document data are first mapped into lower-dimensional feature space, then the SVM classifier is applied to classify documents. The experimental results demonstrate that the proposed algorithm achieves much better performance than other traditional document classification algorithms.
Decolonizing my hair, unshackling my curls: an autoethnography on what makes my natural hair journey a Black feminist statement

ABSTRACT There is unquestionably a buzz in US Black women’s communities about a trending “natural” phenomenon. Sales of chemical relaxers (sometimes dubbed “creamy crack” among the US Black community) have dropped 34 percent since 2009, while sales of “natural” hair care products that promise to non-chemically enhance or beautify “natural” curls are up exponentially. Corresponding to the rise in sales of “natural” hair care products are beauty blogs, YouTube instructional videos and supportive social groups—such as “natural hair” meet-ups, which have organically emerged for, and been mostly created by, Black women as a tool to support and nurture women as they take this journey. In this article, I use Black feminist P.H. Collins’s work because her understanding of the relationship between knowledge, consciousness and empowerment provides a framework or point of departure for grasping my own lived experience of going “natural” with regards to modes of oppression and methods of resistance.
Book Review: The Oxford Handbook of Sociology and Organization Studies: Classical Foundations and The Oxford Handbook of Sociology, Social Theory and Organization Studies: Contemporary Currents

Why now? In this ‘post-truth’ world of President Trump and Brexit, the vanishing of the traditional large corporation (Davis, 2016), and wide-scale inequality (Picketty, 2014), it seems fitting to return to a collection of work that encourages organizational theorists to reconnect with foundational theories in order to make sense of broader social issues and transformations. In this review, I consider two Handbooks that do just this. The Oxford Handbook of Sociology and Organization Studies, edited by Paul Adler, provides a rapid historical tour of foundational sociologists for organizational theorizing; the blanket premise being that without sociology there would be no organization studies. While it is, on the one hand, depressing that almost 10 years ago the same familiar calls were made for organizational theorists to engage in public debates as they are today, on the other, there seems to be no greater and timely reminder for scholars to return to classics in “seeking guidance on how to theorize large-scale economic transformations” (Adler, 2009, p. 17). Perhaps counter-intuitively, I start with the Afterword. Here Davis and Zald reflect on how canons and classics are determined; they remind the reader of how authors (e.g., Marx, Parsons) may be “included or excluded according to intellectual, social and political environment and approved forms of rhetoric holding sway” at the time (Adler, 2009, p. 17). This recognition of time and context is importantly reflected throughout the chapters of the Handbook. Davis and Zald emphasize Thornton’s (Chapter 2) summary of Stinchcombe’s (1982) six reasons for returning to classics and that continues to ring loud and true today: classics as touchstones, developmental tasks, intellectual small coinage, fundamental ideas, routine science, and rituals. This Handbook of 28 chapters is organized in approximate chronological order, moving through European theorists to American theorists. Readers are initially taken through key tenets and concepts from Tocquville (Swedberg), Marx (Adler; Marens), Weber (Clegg and Lounsbury; du Gay), Durkheim (Dobbin; Hirsch, Fiss and Hoel-Green) and Simmel (Scott; Kanter and Khurana) to Veblen (Hamilton and Petrovic), Commons (Van de Ven and Lifschitz) and Parsons (Heckscher), with additional chapters on distinct thought collectives at the Chicago School (Abbott) and the Columbia School (Haveman). 696423OSS0010.1177/0170840617696423Organization StudiesBook Review book-review2017

Parallel Community Mining in Social Network using Map-reduce

The mobile social network plays an essential role as the spread of information and relationship. This paper proposes a parallel algorithm based on MapReduce for finding community in a mobile social network where individuals communicate with one another using mobile phones with register identification information and analyzes the behavior of the communication patterns with taking the actual call detail records received and dialed by users into account. The proposal algorithm is composed of three main components map, reduce and merge for mining groups and a dynamic programming algorithm for selecting subgroups to combine into a big community. Empirical studies on a large real-world mobile social network show that performance of our algorithm is an effective and fast algorithm for mining community in social network.
PuyoSheet and PuyoDots: simple techniques for adding "button-push" feeling to touch panels

Two simple techniques for touch-panel based portable information devices are proposed. A soft-gel based transparent film named "PuyoSheet" placed over a touch panel provides button-push feeling to the fingertips. Another configuration, soft-gel based small dots, named "PuyoDots", is attached to the backside of a handheld device provides button-edge and button-push feelings to the fingertip(s) that hold the device. Preliminary evaluations indicate that proposed techniques improve "usability" and "preference" without deteriorating input speed or error rate compared with an ordinary touch panel device.
Send Orders of Reprints at Reprints@benthamscience.org Brain Connectivity Studies in Schizophrenia: Unravelling the Effects of Antipsychotics

Impaired brain connectivity is a hallmark of schizophrenia brain dysfunction. However, the effect of drug treatment and challenges on the dysconnectivity of functional networks in schizophrenia is an understudied area. In this review, we provide an overview of functional magnetic resonance imaging studies examining dysconnectivity in schizophrenia and discuss the few studies which have also attempted to probe connectivity changes with antipsychotic drug treatment. We conclude with a discussion of possible avenues for further investigation.
Understanding psychological contract violation and its consequences on mobile shopping applications use in a developing country context

Purpose The purpose of this research is to investigate the influence of psychological contract violation (PCV) on service quality and perceived value, and consequently on users positive word of mouth intention towards mobile shopping applications. The role of personalization as a moderator is further investigated. Design/methodology/approach A descriptive research approach was adopted, and responses were gathered from 252 mobile shopping application users in India, using an online survey. The variance-based partial least square structural equation modelling approach was opted for analysing the research model. Findings The results showed the deleterious effects of PCV on service quality and perceived value. The findings further confirm the significant positive impact of service quality and perceived value on the positive word of mouth intention of users. The role of personalization in mitigating the adverse effects of PCV on perceived value among users of mobile shopping application is highlighted in the study; however, its role in safeguarding service quality is found to be insignificant. Research limitations/implications A study with larger sample of respondents from varied nationalities will aid in generalizing the findings of this research. Originality/value This is the first time that PCV and its consequences have been studied in the context of mobile shopping applications.
Nonlinear simulations of magnetic Taylor‐Couette flow with currentfree helical magnetic fields

Themagnetorotational instability (MRI) in cylindrical Taylor-Couette flow with external helical magnetic field is simulated for infinite and finite aspect ratios. We solve the MHD equations in their small Prandtl number limit and confirm with timedependent nonlinear simulations that the additional toroidal component of the magnetic field reduces the critical Reynolds number from O (106) (axial field only) to O (103) for liquid metals with their small magnetic Prandtl number. Computing the saturated state we obtain velocity amplitudes which help designing proper experimental setups. Experiments with liquid gallium require axial field ∼50 Gauss and axial current ∼4 kA for the toroidal field. It is sufficient that the vertical velocity uz of the flow can be measured with a precision of 0.1 mm/s.We also show that the endplates enclosing the cylinders do not destroy the traveling wave instability which can be observed as presented in earlier studies. For TC containers without and with endplates the angular momentum transport of the MRI instability is shown as to be outwards. (© 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
BMS-936564/MDX-1338: A Fully Human Anti-CXCR4 Antibody Induces Apoptosis In Vitro and Shows Antitumor Activity In Vivo in Hematologic Malignancies

Purpose: CXCR4 has been identified as a prognostic marker for acute myeloid leukemia (AML) and other malignancies. We describe the development and characterization of a fully human antibody to CXCR4 and its application for therapy of AML, non–Hodgkin lymphoma (NHL), chronic lymphoid leukemia (CLL), and multiple myeloma. Experimental Design: Human transgenic mice were immunized with CXCR4-expressing cells, and antibodies reactive with CXCR4 were analyzed for apoptosis induction and ability to interfere with CXCL12-induced migration and calcium flux. In vivo efficacy was determined in multiple AML, NHL, and multiple myeloma xenograft tumors in severe combined immunodeficient mice. Results: BMS-936564/MDX-1338 is a fully human IgG4 monoclonal antibody that specifically recognizes human CXCR4. In vitro studies show that MDX-1338 binds to CXCR4-expressing cells with low nanomolar affinity, blocks CXCL12 binding to CXCR4-expressing cells, and inhibits CXCL12-induced migration and calcium flux with low nanomolar EC50 values. When given as monotherapy, MDX-1338 exhibits antitumor activity in established tumors including AML, NHL, and multiple myeloma xenograft models. In addition, we show that MDX-1338 induced apoptosis on a panel of cell lines and propose that antibody-induced apoptosis is one of the mechanisms of tumor growth inhibition. Conclusions: BMS-936564/MDX-1338 is a potent CXCR4 antagonist which is efficacious as monotherapy in tumor-bearing mice and is currently in phase I for the treatment of relapsed/refractory AML, NHL, CLL, and multiple myeloma.

Meta-Analysis of the Long Term Success Rate of Different Interventions in Benign Biliary Strictures

Background Benign biliary stricture is a rare condition and the majority of the cases are caused by operative trauma or chronic inflammation based on various etiology. Although the initial results of endoscopic, percutaneous and surgical treatment are impressive, no comparison about long term stricture resolution is available. Aims The goal of this study was to compare the long term disease free survival in benign biliary strictures with various etiology after surgery, percutaneous transhepatic—and endoscopic treatment. Methods PubMed, Embase, and Cochrane Library were searched by computer and manually for published studies. The investigators selected the publications according to the inclusion and exclusion criteria, processed the data and assessed the quality of the selected studies. Meta-analysis of data of 24 publications was performed to compare long term disease free survival of different treatment groups. Results Compared the subgroups surgery resulted in the highest long term stricture resolution rate, followed by the percutaneous transhepatic treatment, the multiple plastic stent insertion and covered self-expanding metal stents (SEMS), however the difference was not significant. All compared methods are significantly superior to the single plastic stent placement. Long term stricture resolution rate irrespectively of any therapy is still not more than 84%. Conclusions In summary, the use of single plastic stent is not recommended. Further randomized studies and innovative technical development are required for improving the treatment of benign biliary strictures.
