Distinct representations of configural and part information across multiple face-selective regions of the human brain

Several regions of the human brain respond more strongly to faces than to other visual stimuli, such as regions in the amygdala (AMG), superior temporal sulcus (STS), and the fusiform face area (FFA). It is unclear if these brain regions are similar in representing the configuration or natural appearance of face parts. We used functional magnetic resonance imaging of healthy adults who viewed natural or schematic faces with internal parts that were either normally configured or randomly rearranged. Response amplitudes were reduced in the AMG and STS when subjects viewed stimuli whose configuration of parts were digitally rearranged, suggesting that these regions represent the 1st order configuration of face parts. In contrast, response amplitudes in the FFA showed little modulation whether face parts were rearranged or if the natural face parts were replaced with lines. Instead, FFA responses were reduced only when both configural and part information were reduced, revealing an interaction between these factors, suggesting distinct representation of 1st order face configuration and parts in the AMG and STS vs. the FFA.

Wireless power transfer for access limited wireless underground sensor networks

Wireless underground sensor networks (WUSNs) present a variety of new research challenges. Magnetic induction (MI) based transmission has been proposed to overcome the very harsh propagation conditions in underground communications in recent years. In this approach, induction coils are utilized as antennas in the sensor nodes. This solution achieves larger transmission ranges compared to the traditional electromagnetic (EM) waves based approach. In the past, some efforts have been made to characterize the signal transmission in MI-WUSNs. Those investigations, however, refer mostly to the information transmission. One of the open issues, that may constrain the system design in some of the applications, is the powering of the individual sensor nodes. Due to the low accessibility of the nodes, a new method of wireless power transfer (WPT) for MI-WUSNs is proposed in this work. This method is mainly based on simultaneous signal transmissions from multiple sensor nodes with optimized signal constellations. Furthermore, the optimal scheduling for power transmission and reception is provided, which maximizes the energy efficiency of the network charging procedure. The proposed method is compared with the naive approach and shows a significant improvement of the system performance in terms of energy efficiency.
Translingual grammar induction for conversational systems

We propose an induction algorithm to semi-automate grammar authoring in an interlinguabased machine translation framework. This algorithm is designed for restricted domains within the context of multilingual conversational systems. It uses a pre-existing one-way translation system from some other language to the target language as prior information. It then infers a grammar for the target language. We-demonstrate the system's effectiveness on a weather domain and on a travel domain. We automatically induced Chinese and French grammars for these domains from their English counterparts, and then showed that they can produce high-quality interlingua to be used in translation.

Different routes and forms of uterotonics for treatment of retained placenta: methodological issues

I read the paper authored by Maher et al. that was published in the Journal of Maternal-Fetal & Neonatal Medicine in 2017 [1]. The authors aimed to compare three different uterotonics (oxytocin, carbetocin, and misoprostol) given via three different routes (intraumbilical, intravenous, and sublingual, respectively) in reducing the need for manual removal of placenta. It is obvious that the study was well done; however, some statistical and methodological concerns need to be taken into account. Firstly, the sample size should be calculated in any study based on the previous studies to estimate the effective measure with requested precision [2]. The authors used an unsuitable study for sample size calculation. Harara et al. used intraumbilical misoprostol 800 mg, not sublingual misoprostol 400 mg as Maher et al. [3]. Therefore, the 80% success rate that was assumed for sample size calculation is absolutely unsuitable. On the other hand, Van Beekhuizen et al. reported only 60% success rate with sublingual misoprostol 800 mg [4]. This is nearly similar to the success of oxytocin and carbetocin assumed by Maher et al. and this definitely affects the sample size of the study. Secondly, the authors should clarify exactly the number of finally analyzed women. The study flowchart points to all of the study participants (n1⁄4 281) was finally analyzed for the study outcomes. I wonder how the authors included the patient who did not receive the drugs or with cord avulsion during traction in the final analysis. There were 11 patients should be excluded from the final analysis and this will definitely change the percentage of success rate of all study drugs. Maher et al. missed to report exactly the time of patients’ allocation to the study groups. Additionally, did they take a written or oral consent from them before inclusion? Surprisingly, the authors mentioned in the results that one patient developed pulmonary edema and bronchospasm as she was asthmatic. In spite of mentioning the exclusion criteria, any woman with medical disorders was excluded. Finally, the authors reported that 10 patients at the end of the study were in need for blood transfusion [1]. I could not understand how they decide their need for transfusion. Postdelivery hemoglobin level of women in all groups was nearly similar. Moreover, the authors did not estimate the mean blood loss during labor for patients.

A variant of Pollard's rho Attack on Elliptic Curve Cryptosystems

Elliptic Curve cryptosystems appear to be more secure and efficient when requiring small key size to implement than other public key cryptosystems. Its security is based upon the difficulty of solving Elliptic Curve Discrete Logarithm Problem (ECDLP). This study proposes a variant of generic algorithm Pollardâs Rho for finding ECDLP using cycle detection with stack and a mixture of cycle detection and random walks. The Pollardâs Rho using cycle detection with stack requires less iterations than Pollardâs Rho original in reaching collision. Random walks allow the iteration function to act randomly than the original iteration function, thus, the Pollard rho method performs more efficiently. In practice, the experiment results show that the proposed methods decreases the number of iterations and speed up the computation of discrete logarithm problem on elliptic curves.
An architecture and key management approach for maintaining privacy in location based group services

Location based services are becoming increasingly important to the success and attractiveness of next generation wireless systems. Service providers will use location information to introduce new services and greatly enhance many existing services. Maintaining location privacy is an important requirement that must be met for these services to be widely deployed. It is a challenge to maintain location privacy while still providing the flexible access to location information required to enable a rich set of location based services. In this paper we define a high-level architecture for providing LBS and classify services according to several basic criteria. To support these services we propose a hierarchical key distribution method. Four methods are proposed to deliver hierarchical location information while maintaining privacy. We evaluate the efficiency of the system in terms of message delivery and key management overhead
Powering down for energy efficient peer-to-peer file distribution

Peer to peer (P2P) techniques can reduce the time for file distribution, yet require peers to stay ON to assist others download. We study the total time that peers need to be ON to distribute a file from a server to a set of peers. We show that a P2P system optimized for energy effciency can consume half the energy of one optimized to minimize download time, with minimal additional delay. To achieve this, peers finish in increasing order of upload capacity and behave selfishly, turning off as soon as they finish downloading. We show that the optimal solution is complex, even for as few as three peers, and advocate heuristics for large networks.
Essentials of electronic testing for digital, memory, and mixed-signal VLSI circuits [Book Review]

Today's electronic design and test engineers deal with several types of subsystems, namely, digital, memory, and mixed-signal, each requiring different test and design for testability methods. This book provides a careful selection of essential topics on all three types of circuits. The outcome of testing is product quality, which means "meeting the user's needs at a minimum cost". The book includes test economics and techniques for determining the defect level of VLSI chips. Besides being a textbook for a course on testing, it is a complete testability guide for an engineer working on any kind of electronic device or system or a system-on-a-chip.
p53 Interaction with JMJD3 Results in Its Nuclear Distribution during Mouse Neural Stem Cell Differentiation

Conserved elements of apoptosis are also integral components of cellular differentiation. In this regard, p53 is involved in neurogenesis, being required for neurite outgrowth in primary neurons and for axonal regeneration in mice. Interestingly, demethylases regulate p53 activity and its interaction with co-activators by acting on non-histone proteins. In addition, the histone H3 lysine 27-specific demethylase JMJD3 induces ARF expression, thereby stabilizing p53 in mouse embryonic fibroblasts. We hypothesized that p53 interacts with key regulators of neurogenesis to redirect stem cells to differentiation, as an alternative to cell death. Specifically, we investigated the potential cross-talk between p53 and JMJD3 during mouse neural stem cell (NSC) differentiation. Our results demonstrated that JMJD3 mRNA and protein levels were increased early in mouse NSC differentiation, when JMJD3 activity was readily detected. Importantly, modulation of JMJD3 in NSCs resulted in changes of total p53 protein, coincident with increased ARF mRNA and protein expression. ChIP analysis revealed that JMJD3 was present at the promoter and exon 1 regions of ARF during neural differentiation, although without changes in H3K27me3. Immunoprecipitation assays demonstrated a direct interaction between p53 and JMJD3, independent of the C-terminal region of JMJD3, and modulation of p53 methylation by JMJD3-demethylase activity. Finally, transfection of mutant JMJD3 showed that the demethylase activity of JMJD3 was crucial in regulating p53 cellular distribution and function. In conclusion, JMJD3 induces p53 stabilization in mouse NSCs through ARF-dependent mechanisms, directly interacts with p53 and, importantly, causes nuclear accumulation of p53. This suggests that JMJD3 and p53 act in a common pathway during neurogenesis.
Strategies for Filling a Performance Gap Between Practice and High–Level Competition

JOPERD • Volume 81 No. 6 • August 2010 M any athletes display great sport skills in noncompetitive situations such as during practice, but fail to successfully execute these same skills in competition. This phenomenon, which could be caused by psychological or technical issues (Wang & Goldfine, 2008) raises several important questions: (1) from a technical perspective, why is the good performance of athletes during practice sessions not transferred to actual competition; (2) what are the flaws of training designs that cause a performance gap between practice and high-level competition; and (3) what training strategies can be used to remedy these flaws? Without accurately answering these questions, athletes’ investment of time, effort, and resources may lead to less-than-ideal game performances. The following analysis may help provide the answers to these questions.
Measuring Parental Meta-Emotion: Psychometric Properties of the Emotion-Related Parenting Styles Self-Test

Parental meta-emotion, assessed through interviews, involves parents' philosophy about emotions and has been found to be related to parenting behaviors and children's emotional and social competence (e.g., Gottman, Katz, & Hooven, 1996; Katz & Windecker-Nelson, 2004). The Emotion-Related Parenting Styles Self-Test is a true–false (ERPSST–T/F) self-report version of the meta-emotion interview introduced in a parenting guidebook (Gottman, 1997). Although this test is user-friendly, its psychometric properties have not been evaluated. In the first study, 100 parents (89 mothers, 11 fathers) completed the ERPSST–T/F and evidence was found for the internal consistency and test–retest reliability of the measure (Lee, Hakim-Larson, & Voelker, 2000). In the second study, 31 parents (21 mothers, 10 fathers) completed a Likert-type scale version of the ERPSST (ERPSST–Likert) and the internal consistency of the scales was improved. In addition, the scales were found to correlate in expected directions with other measures of parenting attitudes regarding children's emotional expressions, even after controlling for parent gender and social desirability. These findings provide some preliminary evidence for the reliability and validity of the ERPSST–Likert and provide support for further development of the instrument.
Teacher knowledge and initial teacher education in the English learning and skills sector

Recent reforms of initial teacher education (ITE) in the learning and skills sector (LSS) in England are standards based and emphasise subject specialism. The reforms are underpinned by objectivist epistemological assumptions which are incompatible with socio‐cultural theories of professional knowledge, and ignore the diverse teaching roles and contexts in the sector and wider systemic issues. A qualitative scoping study found that LSS in‐service trainee teachers drew on three types of knowledge resources, or clusters of ‘rules’ for practice, in their teaching: these were related to their subject/vocational area, generic teaching and learning processes and specific learners and groups. Trainees generated knowledge resources through participation in their workplace, ITE course and other social contexts, and from embedded and encoded workplace knowledge. Trainees’ beliefs, values and prior experiences were both a knowledge resource and influenced their engagement with knowledge generation activities. It is argued that using a knowledge resources perspective, which recognises how trainees generate knowledge and seeks to bridge gaps in their access to knowledge resources, would be more effective in supporting trainees’ development than the current reforms.
Cross-Age Reading Buddies and Cultural-Sensitive Literature: Student-Centered English Language Instruction in an Ethiopian Budget School

The Ethiopian government has called for educational improvement, emphasizing the employment of active, student-centered pedagogy. One way of maximizing an interactive learning approach involves blending a cross-age reading buddies program with high-quality, culturally relevant children's literature. Employing descriptive, mixed-method research, this study explored the effectiveness of books and buddies on English language use, motivation, and active learning in an underresourced, “budget” school in Addis Ababa, Ethiopia. The report includes a comparison of traditional workbook exercises to the reading of real books. It gives criteria for choosing literature for children of poverty in a developing country, and it describes a process for preparing older students to share second-language books with younger schoolmates. The results of the study suggest that a limited number of well-chosen books used in the context of cross-age reading buddies can have a positive impact on the frequency of English language usage, as well as on students' motivation to learn English.
LOCALITY-SENSITIVE HASHING FOR LARGE SCALE IMAGE RETRIEVAL

In this article we give an overview of the Localitysensitive Hashing (LSH) used for large scale image retrieval and to solve the nearest neighbor problem. The goal is to experiment with different parameters configurations of LSH over a set of video fingerprints to see which is the best in terms of precision and indexing so that later, given a query object, return the objects (nearest neighbors) that are most similar to the query. The configuration parameters that offered best results were a bucket size of 24 with 15 tables and hash sizes of 15 bits, obtaining about 50% of correct matches with P@4 and P@6 retrieval methods.
Centrifugal enhancement of human immunodeficiency virus type 1 infection and human cytomegalovirus gene expression in human primary monocyte/macrophages in vitro

In an effort to facilitate the efficiency of human immunodeficiency virus type 1 (HIV‐1) and/or human cytomegalovirus (HCMV) infection in primary monocyte/macrophages in vitro, the effect of low‐speed centrifugation was studied. The infectivity of Aree strains (Bai, Ada‐M, and IIIB) of HIV‐1 tested was significantly enhanced by centrifugal inoculation at a force of 1500g for 60 min. Reverse transcriptase activity and HIV‐1 p24 antigen in primary monocyte/macrophages infected by a centrifugal inoculation technique were detectable 3‐7 days earlier and were more than 10‐fold greater in magnitude (at an early stage of the infection) than those of control cells infected by the conventional inoculation technique. Examination of the cells by indirect immunofluorescence revealed higher expression of HIV‐1 p24 protein in the monocyte/macrophages infected by the centrifugal inoculation technique. These differences were directly related to centrifugal inoculation and were evident up to 3 weeks after infection. Enhancement was not observed when centrifugation was carried out before or after HIV‐1 infection. Centrifugal inoculation of HCMV also enhanced its immediate‐early and early gene expression up to 36‐ to 50‐fold, although neither late nuclear antigens and glycoproteins of HCMV nor infectious virus was detected in HCMV‐infected monocyte/ macrophage cultures. These results show that centrifugal inoculation is a useful technique for improving the efficiency of HCMV and HIV‐1 infection in vitro.
Bug Tracking and Reliability Assessment System (BTRAS)

Tracking of a reported bug for fixing is a fascinating area of research in software engineering. Many open source, free and commercial bug tracking tools have been developed and are currently under development. The industry needs criteria to select the best tool among the available set of tools that will help in fixing and tracking the progress of bug fixes. In this paper, we use BugZilla, Jira, Trac, Mantis, BugTracker.Net, Gnats and Fossil for comparative study. We present a comprehensive classification criteria to review the available tools and propose a new tool named Bug Tracking and Reliability Assessment System (BTRAS) for the bug tracking/reporting and reliability assessment. BTRAS helps in reporting the bug, assigning the bug to the developer for fixing, monitoring the progress of bug fixing by various graphical/charting facility and status updates, providing reliability bug prediction and bug complexity measurements, and distributing fixes to users/developers.
Long Term Memory for Noise: Evidence of Robust Encoding of Very Short Temporal Acoustic Patterns

Recent research has demonstrated that humans are able to implicitly encode and retain repeating patterns in meaningless auditory noise. Our study aimed at testing the robustness of long-term implicit recognition memory for these learned patterns. Participants performed a cyclic/non-cyclic discrimination task, during which they were presented with either 1-s cyclic noises (CNs) (the two halves of the noise were identical) or 1-s plain random noises (Ns). Among CNs and Ns presented once, target CNs were implicitly presented multiple times within a block, and implicit recognition of these target CNs was tested 4 weeks later using a similar cyclic/non-cyclic discrimination task. Furthermore, robustness of implicit recognition memory was tested by presenting participants with looped (shifting the origin) and scrambled (chopping sounds into 10− and 20-ms bits before shuffling) versions of the target CNs. We found that participants had robust implicit recognition memory for learned noise patterns after 4 weeks, right from the first presentation. Additionally, this memory was remarkably resistant to acoustic transformations, such as looping and scrambling of the sounds. Finally, implicit recognition of sounds was dependent on participant's discrimination performance during learning. Our findings suggest that meaningless temporal features as short as 10 ms can be implicitly stored in long-term auditory memory. Moreover, successful encoding and storage of such fine features may vary between participants, possibly depending on individual attention and auditory discrimination abilities. Significance Statement Meaningless auditory patterns could be implicitly encoded and stored in long-term memory. Acoustic transformations of learned meaningless patterns could be implicitly recognized after 4 weeks. Implicit long-term memories can be formed for meaningless auditory features as short as 10 ms. Successful encoding and long-term implicit recognition of meaningless patterns may strongly depend on individual attention and auditory discrimination abilities.
Parallel subdivision surface rendering and animation on the Cell BE processor

Subdivision Surfaces provide a compact way to describe a smooth surface using a mesh model. They are widely used in 3D animation and nearly all modern modeling programs support them. In this work we describe a complete parallel pipeline for real-time interactive editing, processing and rendering of smooth surface primitives on the Cell BE. Our approach makes it possible to edit and render these high-order graphics primitives passing them directly to a parallel pipeline which tessellates them just before rendering. We describe a combination of algorithmic, architectural and back-end optimizations that enable us to render smooth subdivision surfaces in real time and to dynamically deform 3D models represented by subdivision surfaces.
