A 464GOPS 620GOPS/W heterogeneous multi-core SoC for image-recognition applications

The use of image recognition technologies is becoming more popular recently in a variety of industries such as automotive, surveillance, and others. SoCs for such image recognition applications are required to be powerful enough to support real-time multiple object recognition, with power consumption not exceeding a few Watts. Adaptability to a range of applications is also desirable. In this context, massively parallel processors and heterogeneous many-core processors with 200GOPS have been proposed. However, rising demands for simultaneous execution of multiple applications leads to even higher performance requirements. In advanced driver-assistance systems for automotive, for example, forward collision warning and traffic sign recognition should execute simultaneously to improve safety of the system. In addition, the accuracy of recognition is also important. With its high accuracy (96% detection rate/0.1% false-positive rate), object recognition using co-occurrence histograms of oriented gradients (CoHOG) is a promising algorithm. However, the algorithm requires an extensive amount of computation. For example, a desktop computer with a 3GHz quad-core processor is needed for CoHOG-based pedestrian detection in a backover prevention (BOP) application. Considering these requirements, we have developed an image recognition SoC with the following features: 1) a multi-core processor to provide adaptability to various applications; 2) accelerators for image processing tasks and image recognition tasks to realize high performance at low power consumption; and, 3) a hardware accelerator for a CoHOG based real-time recognition.
Why borderline personality disorder is neither borderline nor a personality disorder

Objectives Borderline personality disorder is the most well-studied personality disorder in psychiatry. Despite its great influence in the study of these conditions, it has not been properly recognized that borderline personality disorder is atypical. Design A critical analysis of the differences between borderline and other personality disorders is made. Method A comparison is made between borderline personality disorder and other personality disorders with respect to diagnostic criteria, relationship to normal personality variation and treatment options. Results Analysis of the operational criteria for borderline and schizotypal personality disorders shows that these are the only personality disorders that are dominated by discrete symptoms rather than traits. Cluster analysis of a data set of personality traits obtained between 1976 and 1978 (before borderline personality disorder became fashionable in the UK) could find no profile that supports the existence of a borderline personality disorder grouping, and the study of published papers on treatment in personality disorder shows a 3 : 1 ratio for borderline personality disorder compared with all other personality disorders combined, approaching 9 : 1 when unspecified (probably mainly borderline) conditions are taken into account. Conclusions Borderline personality disorder is incorrectly classified as a personality disorder and does an injustice to those who suffer from it. It is better classified as a condition of recurrent unstable mood and behaviour, or fluxithymia, which is better placed with the mood disorders than in odd isolation as a personality disorder.

Intercellular electrical communication among smooth muscle and endothelial cells in guinea‐pig mesenteric arterioles

1 Current clamp studies using two patch electrodes and morphological observations have been performed in guinea‐pig mesenteric arterioles to evaluate intercellular electrical couplings. 2 In electron micrographs, preparations were found to have a single layer of smooth muscle cells. Typical gap junctions were readily observed between endothelial cells only. 3 While immunoreactivity to connexin 40 was strongly expressed on the membranes of endothelial cells only, that to connexin 43 was expressed on both smooth muscle and endothelial cell membranes. 4 Neurobiotin injected into a smooth muscle cell diffused into several neighbouring smooth muscle cells while that injected into an endothelial cell diffused into many endothelial cells. 5 Acetylcholine‐induced hyperpolarizations were conducted from endothelial cells to smooth muscle cells with a relative amplitude of 80.1 %. Ba2+‐induced action potentials were conducted in the opposite direction with a relative amplitude of 92.4 %. 6 An electrotonic potential produced in a smooth muscle cell by current injection diminished steeply with distance as it spread along the muscle layer, plateauing at distances beyond 25 μm. An electrotonic potential produced in an endothelial cell spread within the intima with virtually no reduction. Electrotonic potentials could conduct through myoendothelial couplings, which seemed to behave as ohmic resistors without rectification. 7 The coupling resistance between adjacent smooth muscle cells was estimated to be at least 90 MΩ and that between a smooth muscle cell and the whole endothelial layer to be 0.9 GΩ. 8 The results indicate that although the resistance of myoendothelial couplings is appreciable, the endothelium may be important as a low resistance path connecting many smooth muscle cells.

Visualizing Project Evolution through Abstract Syntax Tree Analysis

What is a developer's contribution to a repository? By only counting commits and number of lines changed, existing tools that visualize source code repositories (such as GitHub's graphs) fall short on showing the effective contributions made by each developer. When many commits are viewed as a group, the details are lost. Commit information can be misleading since lines of code give no indication of what was actually being worked on without careful examination of the changed code. Providing a semantic view of this information could provide deeper insights into how software projects evolve since changes to design and features are not clearly visible from line changes alone. We present TypeV: a method for visualizing Java source code repositories. Instead of counting line changes in a commit we extract detailed type information over time by using the differences between abstract syntax trees (ASTs). We are then able to track the additions and deletions of declarations and invocations for each type. Furthermore, we can track each author's type usage over time. Using TypeV, we examine specific cases in well-known repositories where our tool reveals interesting and useful information. We then compare type coverage information from the AST compared to file coverage to determine if unique information is provided by type information.
Software test effort estimation

Software Testing is an important process of software development that is performed to support and enhance reliability and quality of the software. It consist of estimating testing effort, selecting suitable test team, designing test cases, executing the software with those test cases and examining the results produced by those executions. Studies indicate that more than fifty percent of the cost of software development is devoted to testing, with the percentage for testing critical software being even higher. Unless we can predict the testing effort and find efficient ways to perform effective testing, the percentage of development costs devoted to testing will increase significantly coupled with mismatch in project costing and development schedule. In order to estimate the testing effort, this paper makes an attempt to establish Cognitive Information Complexity Measure (CICM) as an appropriate estimation tool.
Effect of Automated BioBehavioral Feedback on the Control of Type 1 Diabetes

RESEARCHDESIGNANDMETHODS—For 1 year, 120 adults with type 1 diabetes (69 female/51 male, age = 39.1 [14.3] years, duration of diabetes 20.3 [12.9] years, HbA1c = 8.0 [1.5]), performed self-monitoring of blood glucose (SMBG) and received feedback at three increasingly complex levels, each continuing for 3 months: level 1—routine SMBG; level 2—adding estimated HbA1c, hypoglycemia risk, and glucose variability; and level 3—adding estimates of symptoms potentially related to hypoglycemia. The subjects were randomized to feedback sequences of either levels 1-2-3 or levels 2-3-1. HbA1c, symptomatic hypoglycemia, and blood glucose awareness were evaluated at baseline and at the end of each level.
The turn to work in organization and management theory: Some implications for strategic organization

Over the past decade, the study of management and organization theory has experienced a significant ‘turn to work’. This turn to work has not, however, been a return to the study of the forms of work that have been the traditional focus of organizational scholars. Instead, the turn to work involves a widespread scholarly engagement with new forms of work that involve individuals and organizations purposefully and strategically expending effort to affect their social-symbolic context. For example, boundary work (Gieryn, 1983; Kreiner et al.,2009), identity work (Ibarra and Barbulescu, 2010; Watson, 2008) and institutional work (Lawrence and Suddaby, 2006; Zietsma and Lawrence,2010) have all become important areas of scholarship despite being largely unknown or unexplored just a few years ago. Although the streams of research on various new forms of work are largely disconnected at present, we argue that together they represent an important trend in the study of management and organization with important ramifications for researchers interested in strategic organization. In this essay, we introduce the turn to work, explain what it is and why it has occurred, discuss its implications for the field of strategic organization and propose some new research directions for strategic organization that incorporate this turn to work.
A snake robot with a contact force measurement system for obstacle-aided locomotion

A snake robot can traverse cluttered and irregular environments by using irregularities around its body as push-points to aid the propulsion. This is denoted obstacle-aided locomotion and requires the snake robot to have two features: 1) a smooth exterior surface combined with 2) a contact force sensing system. These two features are characteristic of biological snakes, but have received limited attention in snake robot designs so far. This paper describes the development of a new snake robot aimed at meeting both these requirements. The paper details the design and implementation of the snake robot, presents experimental results that validate the function of the contact force measurement system, and demonstrates some of the motion capabilities of the robot.
Efficient Execution of Dependent Tasks on Many-Core Processors

The increasing performance requirements of safety-critical real-time embedded systems made traditional single-core architectures obsolete. Moving to more complex many-core systems requires new techniques and tools for the certification of the embedded software. Timing and functional behaviours are subject to specific requirements of certification guidelines such as D-178B/C for avionics and ISO26262 for automotive systems. Determinism and predictability of such systems are a major challenge. Running tasks should be known in advance which makes the static and non-preemptive scheduling a suitable approach to reach an optimal execution with a guarantee of a certain degree of determinism. Recent work on mapping and scheduling problems [1], [2], [3] consider a known value (or a set of possible values) of the Worst-Case Response Time (WCRT) and computes a mapping that optimizes a predefined cost function. When the response time analysis is too pessimistic, the static scheduling may introduce an idle time which reduces the core utilization. Scheduling techniques must rely on tight estimations of the WCRT which in turn depends on co-runner tasks. However, in order to obtain a tight upper-bound on the response time, a mapping and scheduling should be known in advance. Indeed, the response time is highly influenced by the co-runner tasks. Concurrent accesses to the same shared resource may introduce interferences that should be accounted for in the response time analysis. The search for an optimal scheduling with a tight WCRT analysis that includes the shared resource interferences is a challenging open problem.
Predicting Jealous Responses: The Influence of Adult Attachment and Depression on Threat Appraisal

This study tested a model of romantic jealousy based on cognitive motivational theory (White & Mullen, 1989) and formulations from adult attachment studies (Hazan & Shaver, 1987). A causal model was tested in which attachment, depression and situational threat were hypothesized to predict jealous responses through their effects on appraisal of threat. Imagery scenes, depicting varying levels of threat by a romantic relationship rival, were presented to 135 undergraduates. The model fit the data very well. Threat appraisal was predicted by attachment, depression and level of situational threat. Appraisal, in turn, predicted positive and negative relationship perceptions and emotions reported in response to jealousy-evoking situations. Results were interpreted as suggesting that attachment style and depression indirectly influence affective and cognitive responses to jealousy-evoking situations by functioning as schemas which influence the appraisal of a rival relationship. Insecure attachment and depression were also found to be related to less effective coping strategies. Findings regarding depression and ineffective coping suggested implications for the personal and relationship adjustment of persons with secure and insecure attachment.
Analysis of Distance Collaboration Modalities: Alternatives to Meeting Face-to-Face

Physical and temporal boundaries are rapidly diminishing in an age of swiftly advancing information communication technologies. Today’s technologically sophisticated business and organizational environments offer a number of distance collaboration modalities (DSMs) that can facilitate efficient and cost-effective meetings that have traditionally required face-to-face meeting venues. Selection of the DCMs that maximize meeting effectiveness is significantly challenging given the wide diversity of available options. Theory and empirical data can be useful as a guide in the selection of the most appropriate DCMs to maximize organizational productivity and success. This article reviews the literature on the behavioral and technical affordances and limitations of the various DCMs. It also provides a theoretical model based on media synchronicity theory to help guide selection of effective DCMs. This theoretical framework emphasizes the primacy of media alignment with core communication processes as well as social and interpersonal factors that influence meeting effectiveness.
Calcium and vitamin D intake and risk of incident premenstrual syndrome.

BACKGROUND Premenstrual syndrome (PMS) is one of the most common disorders of premenopausal women. Studies suggest that blood calcium and vitamin D levels are lower in women with PMS and that calcium supplementation may reduce symptom severity, but it is unknown whether these nutrients may prevent the initial development of PMS. METHODS We conducted a case-control study nested within the prospective Nurses' Health Study II cohort. Participants were a subset of women aged 27 to 44 years and free from PMS at baseline in 1991, including 1057 women who developed PMS over 10 years of follow-up and 1968 women reporting no diagnosis of PMS and no or minimal menstrual symptoms. Intake of calcium and vitamin D was measured in 1991, 1995, and 1999 by a food frequency questionnaire. RESULTS After adjustment for age, parity, smoking status, and other risk factors, women in the highest quintile of total vitamin D intake (median, 706 IU/d) had a relative risk of 0.59 (95% confidence interval, 0.40-0.86) compared with those in the lowest quintile (median, 112 IU/d) (P = .01 for trend). The intake of calcium from food sources was also inversely related to PMS; compared with women with a low intake (median, 529 mg/d), participants with the highest intake (median, 1283 mg/d) had a relative risk of 0.70 (95% confidence interval, 0.50-0.97) (P = .02 for trend). The intake of skim or low-fat milk was also associated with a lower risk (P<.001). CONCLUSIONS A high intake of calcium and vitamin D may reduce the risk of PMS. Large-scale clinical trials addressing this issue are warranted. Given that calcium and vitamin D may also reduce the risk of osteoporosis and some cancers, clinicians may consider recommending these nutrients even for younger women.
Reliable NCO carrier generators for GPS receivers

Four strategies for upset protection in NCO (Numerically controlled oscillator) generators are presented and compared in this paper1. This work is motivated by the increased prevalence of single event upsets due to process/voltage/temperature variations coupled with the increased advancement of CMOS technology. The occurrence of these upsets in the GPS context (the system under the test in this paper) can lead to a loss of the GPS signal tracking, then the corresponding satellite signal must be re-acquired resulting in high energy expenditure and time delay. It can result also in a corrupted position given by the GPS receiver. Results of experiment using a GPS receiver design are presented in this paper to evaluate the performance of proposed methods. This work can be extended and generated to any system using feedback loops information.
Feasibility study of applying LTE to Smart Grid

Smart Grid (SG) is characterized by two-way flow of electricity and information and is capable of monitoring everything from power plants and customer preference to individual appliances. In this paper, we focus on applying 3GPP LTE release 8 technology to build a high-reliable and low-latency Distribution Automation (DA) network. Based on the documents released by Nation Institute of Standard and Technologies, the communication requirements of DA are obtained, which include traffic distributions, latency constraint and reliability requirement. The latency and reliability requirements are tightly coupled in the DA network. In order to mitigate queueing delay, we reserve bandwidth only for the devices with low duty cycle random traffics. By maintaining all field devices in RRC-CONNECTED state, the scheduling delay can be decreased to 66 ms as maximum, this leaves time to complete three retransmissions of devices' data. Finally, the uplink and downlink cell-edge Interference-plus-Noise Ratios are estimated through system level simulation. The reliability requirements of DA can be satisfied with 4-by-2 Transmission Mode 6 system in downlink, and with 1-by-4 system in uplink, respectively. Therefore, we conclude that LTE is a promising candidate to build a wireless DA network.
Formation of the asymmetric pineal complex in zebrafish requires two independently acting transcription factors

The pineal complex of zebrafish consists of a pineal organ and a left‐sided parapineal organ. Mutation of the floating head (flh) gene, which encodes a homeodomain protein, causes premature termination of pineal cell division without affecting specification or asymmetric placement of the parapineal. The from beyond (fby) mutation, a premature stop codon in the T‐domain‐containing protein Tbx2b, disrupts formation of the parapineal while leaving the pineal largely intact. However, flh is reported as being required for tbx2b transcription. To resolve the paradox that flhand tbx2b mutants have opposite phenotypes but have been placed in the same genetic pathway, we have examined transcriptional cross‐regulation in single flh or fby mutants and genetic epistasis in double mutants. Careful analysis shows that flh is not required for tbx2b transcription and double mutants exhibit an additive phenotype. We conclude that Flh and Tbx2b regulate separate programs of pineal and parapineal development. Developmental Dynamics 237:3538–3544, 2008. © 2008 Wiley‐Liss, Inc.
Dlg, Scribble and Lgl in cell polarity, cell proliferation and cancer.

Dlg (Discs large), Scrib (Scribble) and Lgl (Lethal giant larvae) are evolutionarily conserved components of a common genetic pathway that link the seemingly disparate functions of cell polarity and cell proliferation in epithelial cells. dlg, scrib and lgl have been identified as tumour suppressor genes in Drosophila, mutations of which cause similar phenotypes, involving disruption of cell polarity and neoplastic overgrowth of tissues. The molecular mechanisms by which Dlg, Scrib and Lgl proteins regulate cell proliferation are not clear, but there is some evidence that epithelial polarisation is required for this regulation. Dlg, Scrib and Lgl are highly conserved between human and Drosophila, and we discuss evidence that these proteins also play a role in cancer progression in humans.
Simplified adsorption method for detection of antibodies to Candida albicans germ tubes

Two modifications that simplify and shorten a method for adsorption of the antibodies against the antigens expressed on both blastospore and germ tube cell wall surfaces (methods 2 and 3) were compared with the original method of adsorption (method 1) to detect anti-Candida albicans germ tube antibodies in 154 serum specimens. Adsorption of the sera by both modified methods resulted in titers very similar to those obtained by the original method. Only 5.2% of serum specimens tested by method 2 and 5.8% of serum specimens tested by method 3 presented greater than one dilution discrepancies in the titers with respect to the titer observed by method 1. When a test based on method 2 was evaluated with sera from patients with invasive candidiasis, the best discriminatory results (sensitivity, 84.6%; specificity, 87.9%; positive predictive value, 75.9%; negative predictive value, 92.7%; efficiency, 86.9%) were obtained when a titer of > or = 1:160 was considered positive.
Critical points via Gamma-convergence: general theory and applications

It is well-known that Γ-convergence of functionals provides a tool for studying global and local minimizers. Here we present a general result establishing the existence of critical points of a Γ-converging sequence of functionals provided the associated Γ-limit possesses a nondegenerate critical point, subject to certain mild additional hypotheses. We then go on to prove a theorem that describes suitable non-degenerate critical points for functionals, involving the arclength of a limiting singular set, that arise as Γ-limits in a number of problems. Finally, we apply the general theory to prove some new results, and give new proofs of some known results, establishing the existence of critical points of the 2d Modica-Mortola (Allen-Cahn) energy and 3d Ginzburg-Landau energy with and without magnetic field, and various generalizations, all in a unified framework.
