Energy-adaptive codes

We provide the first constructions of a new family of error-correcting codes called “energy-adaptive codes. ” These codes are designed to enable adaptive circuit implementations that minimize the total system-level energy based on varying distances and target error probabilities. Recent work has explored fundamental limits and practical strategies for minimizing total (transmit + circuit) power, considering both power consumed in computational nodes as well as wires in the circuit. It is now established that to minimize total power, code choice and circuit-design should change with communication distances and/or target error probability. Motivated by circuit area constraints, the energy-adaptive codes adapt energy consumption as distances and/or target error probability change. These codes shrink and expand the wiring area they occupy as demands on the system change, adjusting the hardware by turning on and off non-local wires in the circuit. The code constructions are hierarchical, and use QC-LDPC codes as the basis. We estimate the decoding power savings attained by use of these codes through simulation results. Such codes can be of increasing utility as we enter the era of 1000 devices per person where designing the skilled labor for obtaining optimized designs for each system will simply be unavailable. While our first constructions are admittedly simplistic, the goal of the paper is to bring this new problem to the attention of the coding-theory community.
Interviewer Effects in the Measurement of Personal Network Size A Nonexperimental Study

Methods for delineating personal networks in surveys contain complex instructions for the interviewers. It is assumed that the interviewers' experience and education influence their ability to follow these instructions. The magnitude of the interviewer effects on the personal network size has been investigated, and differences among interviewers have been explained on the basis of their experience and education. The data are from a survey among 4,059 older adults in the Netherlands interviewed in 1992 by 87 interviewers. A strong interviewer effect was observed. Furthermore, the results of a multilevel regression analysis showed that, controlled for respondent characteristics, well-educated interviewers with minor experience prior to the project and major experience within the project (i.e., the high sequence number of the interview) generated relatively large networks.
Comprehensive Serology Based on a Peptide ELISA to Assess the Prevalence of Closely Related Equine Herpesviruses in Zoo and Wild Animals

Equine herpesvirus type 1 (EHV-1) causes respiratory disorders and abortion in equids while EHV-1 regularly causes equine herpesvirus myeloencephalopathy (EHM), a stroke-like syndrome following endothelial cell infection in horses. Both EHV-1 and EHV-9 infections of non-definitive hosts often result in neuronal infection and high case fatality rates. Hence, EHV-1 and EHV-9 are somewhat unusual herpesviruses and lack strict host specificity, and the true extent of their host ranges have remained unclear. In order to determine the seroprevalence of EHV-1 and EHV-9, a sensitive and specific peptide-based ELISA was developed and applied to 428 sera from captive and wild animals representing 30 species in 12 families and five orders. Members of the Equidae, Rhinocerotidae and Bovidae were serologically positive for EHV-1 and EHV-9. The prevalence of EHV-1 in the sampled wild zebra populations was significantly higher than in zoos suggesting captivity may reduce exposure to EHV-1. Furthermore, the seroprevalence for EHV-1 was significantly higher than for EHV-9 in zebras. In contrast, EHV-9 antibody prevalence was high in captive and wild African rhinoceros species suggesting that they may serve as a reservoir or natural host for EHV-9. Thus, EHV-1 and EHV-9 have a broad host range favoring African herbivores and may have acquired novel natural hosts in ecosystems where wild equids are common and are in close contact with other perissodactyls.
Opinions of University Students About Language Teaching

University language students, writing in the essay portion of a recent departmental opinion questionnaire, clearly indicate that they wish more speaking practice and less ritualized grammar in their language training. Rather than studying language as if it were a museum exhibit under glass, they prefer experiencing its live, practical aspects in such a way that they can gain mastery over a central core of high-frequency usage for their daily use. They also want professors who are willing to teach living language and who are enough interested in their students to use many different media in conducting this exploration of knowledge with them. The students themselves devise a list of good language-teaching ideas for the resourceful teacher. These opinions are not frivolous; they are honest attempts at communication between student and teacher and provide clues to the language-training needs of today's students.
Capital Structure and Financial Risk: Evidence from Foreign Debt Use in East Asia

Using a data set of East Asian nonfinancial companies, we examine a firm's choice between local, foreign, and synthetic local currency (hedged foreign currency) debt. We find evidence of unique as well as common factors that determine each debt type's use, indicating the importance of examining debt at a disaggregated level. We exploit the Asian financial crisis as a natural experiment to investigate the role of debt type in firm performance. Surprisingly, we find that the use of synthetic local currency debt is associated with the biggest drop in market value, possibly due to currency derivative market illiquidity during the crisis.

A simple model of convection with memory

[1] There are at least three distinct time scales that are relevant for the evolution of atmospheric convection. These are the time scale of the forcing mechanism, the time scale governing the response to a steady forcing, and the time scale of the response to variations in the forcing. The last of these, tmem, is associated with convective life cycles, which provide an element of memory in the system. A highly simplified model of convection is introduced, which allows for investigation of the character of convection as a function of the three time scales. For short tmem, the convective response is strongly tied to the forcing as in conventional equilibrium parameterization. For long tmem, the convection responds only to the slowly evolving component of forcing, and any fluctuations in the forcing are essentially suppressed. At intermediate tmem, convection becomes less predictable: conventional equilibrium closure breaks down and current levels of convection modify the subsequent response.
The principalship in developing countries: context, characteristics and reality

This article seeks to shed light on the contexts and characteristics of principalship in developing countries, as well as to examine similarities and differences between principals in developed and developing countries. Twenty‐seven papers constitute the data on which external influences on principalship, patterns of leadership styles and managerial aspects of the principal's role are analysed. Although there is no one portrait of school principalship in developing countries, some common features were revealed, such as limited autonomy, autocratic leadership style, summative evaluation, low degree of change initiation, and lack of instructional leadership functions. Theoretical implications and suggestions for educational policy and reforms are presented.
Structural neuroimaging studies in major depressive disorder. Meta-analysis and comparison with bipolar disorder.

CONTEXT Although differences in clinical characteristics exist between major depressive disorder (MDD) and bipolar disorder (BD), consistent structural brain abnormalities that distinguish the disorders have not been identified. OBJECTIVES To investigate structural brain changes in MDD using meta-analysis of primary studies; assess the effects of medication, demographic, and clinical variables; and compare the findings with those of a meta-analysis of studies on BD. DATA SOURCES The MEDLINE, EMBASE, and PsycINFO databases were searched for studies from January 1, 1980, to February 2, 2010. STUDY SELECTION Two hundred twenty-five studies that used magnetic resonance imaging or x-ray computed tomography to compare brain structure in patients with MDD with that of controls were included in an online database, and 143 that measured common brain structures were selected for meta-analysis. DATA EXTRACTION Twenty-five variables, including demographic and clinical data, were extracted from each study, when available. For the meta-analysis, mean structure size and standard deviation were extracted for continuous variables, and the proportion of patients and controls with an abnormality in brain structure was extracted for categorical variables. DATA SYNTHESIS Compared with the structure of a healthy brain, MDD was associated with lateral ventricle enlargement; larger cerebrospinal fluid volume; and smaller volumes of the basal ganglia, thalamus, hippocampus, frontal lobe, orbitofrontal cortex, and gyrus rectus. Patients during depressive episodes had significantly smaller hippocampal volume than patients during remission. Compared with BD patients, those with MDD had reduced rates of deep white matter hyperintensities, increased corpus callosum cross-sectional area, and smaller hippocampus and basal ganglia. Both disorders were associated with increased lateral ventricle volume and increased rates of subcortical gray matter hyperintensities compared with healthy controls. CONCLUSIONS The meta-analyses revealed structural brain abnormalities in MDD that are distinct from those observed in BD. These findings may aid investigators attempting to discriminate mood disorders using structural magnetic resonance imaging data.
Expression of connexins 40 and 43 in human left atrium in atrial fibrillation of different aetiologies

Objective: To test the hypothesis that atrial fibrillation (AF) is associated with changes in the expression of connexins 40 and 43 in the left atrium with more pronounced changes in mitral valve disease than in lone AF. Methods: Protein concentrations of connexin 40 and connexin 43 were analysed in left atrial tissue of patients undergoing cardiac surgery. One group of patients had lone AF (n = 41), one group had AF and mitral valve repair (n = 36), and one group in sinus rhythm served as controls (n = 15). Results: Western blot analysis of connexin 40 and connexin 43 expression showed an increase of both gap junctional proteins (connexin 43 > connexin 40) in patients with AF of all forms compared with patients in sinus rhythm (p = 0.01 and p = 0.011, respectively). Subgroup analysis showed increased concentrations of connexin 40 in lone AF and AF with mitral valve disease compared with sinus rhythm (p = 0.06 and p = 0.029, respectively), whereas the same analysis for connexin 43 reached significance only in the mitral valve disease group (p = 0.031). No differences in connexin 40 and connexin 43 expression were detectable between lone AF and AF with mitral valve disease. Within the groups connexin 40 and connexin 43 expression did not differ between patients with paroxysmal AF and patients with chronic AF. Conclusion: The present study shows for the first time that AF can induce changes in the left atrium with increased connexin expression. Furthermore, no systematic differences between patients with paroxysmal and chronic AF were detected.
What Are the Syndromes of Behavioral and Psychological Symptoms of Dementia?

Syndromes are clusters of symptoms that tend to occur together in the same patient. They usually are described crosssectionally (i.e., the symptoms occur in the same individual at the same time) but can also occur longitudinally (i.e., the symptoms occur in the same individual but at different times).
PDK1 regulates growth through Akt and S6K in Drosophila

The insulin/insulin-like growth factor-1 signaling pathway promotes growth in invertebrates and vertebrates by increasing the levels of phosphatidylinositol 3,4,5-triphosphate through the activation of p110 phosphatidylinositol 3-kinase. Two key effectors of this pathway are the phosphoinositide-dependent protein kinase 1 (PDK1) and Akt/PKB. Although genetic analysis in Caenorhabditis elegans has implicated Akt as the only relevant PDK1 substrate, cell culture studies have suggested that PDK1 has additional targets. Here we show that, in Drosophila, dPDK1 controls cellular and organism growth by activating dAkt and S6 kinase, dS6K. Furthermore, dPDK1 genetically interacts with dRSK but not with dPKN, encoding two substrates of PDK1 in vitro. Thus, the results suggest that dPDK1 is required for dRSK but not dPKN activation and that it regulates insulin-mediated growth through two main effector branches, dAkt and dS6K.
“There Is a Spirit in that Image”: Mass-Produced Jesus Pictures and Protestant-Pentecostal Animation in Ghana

In southern Ghana, where I have been conducting research on the genesis of popular Christianity for almost twenty years, Christian imagery is everywhere. The Ghanaian state re-adopted a democratic constitution in 1992, and this was followed by a liberalization and commercialization of mass media, which in turn facilitated the spread of Pentecostalism in the public sphere (see De Witte 2008; Gifford 2004; Meyer 2004a). Within this process, Christian pictures have become ubiquitous. Pentecostal-charismatic churches assert their public presence and power via television, radio, posters, and stickers, and there has also emerged a new public culture rife with Christian imagery. This visual and aural expansion of Christianity and its particular aesthetic severely challenges what is being called African Traditional religion, and clashes with initiatives developed by the state and intellectuals to secure a national heritage.
Impact of Content-Specific Email Reminders on Provider Participation in an Online Intervention: A Denta PBRN Study

Engaging busy healthcare providers in online continuing education interventions is challenging. In an Internet-delivered intervention for dental providers, we tested a series of email-delivered reminders - cues to action. The intervention included case-based education and downloadable practice tools designed to encourage providers to increase delivery of smoking cessation advice to patients. We compared the impact of email reminders focused on 1) general project announcements, 2) intervention related content (smoking cessation), and 3) unrelated content (oral cancer prevention focused content). We found that email reminders dramatically increased participation. The content of the message had little impact on the participation, but day of the week was important - messages sent at the end of the week had less impact, likely due to absence from clinic on the weekend. Email contact, such as day of week an email is sent and notice of new content post-ing, is critical to longitudinal engagement. Further research is needed to understand which messages and how frequently, will maximize participation.
Polarimetric observations of GRB 011211

We present and discuss polarimetric observations performed with the VLT-UT3 (Melipal) on the afterglow of GRB 011211, 35 hours after the burst onset. The observations yielded a 3 upper limit of P < 2:7%. We discuss this result in combination with the lightcurve evolution, that may show a break approximately at the time of our observation. We show that our upper limit is consistent with the currently favored beamed fireball geometry, especially if the line of sight was not too close to the edge of the cone.
The RNA Binding Protein Csx1 Promotes Sexual Differentiation in Schizosaccharomyces pombe

Sexual differentiation is a highly regulated process in the fission yeast Schizosaccharomyces pombe and is triggered by nutrient depletion, mainly nitrogen source. One of the key regulatory proteins in fission yeast sexual differentiation is the transcription factor Ste11. Ste11 regulates the transcription of many genes required for the initial steps of conjugation and meiosis, and its deficiency leads to sterility. Ste11 activity is mainly regulated at two levels: phosphorylation and abundance of its mRNA. Csx1 is an RNA binding protein that we have previously described to bind and regulate the turnover rate of the mRNA encoding the transcription factor Atf1 in the presence of oxidative stress. We have observed that Csx1-deficient cells have defects in sexual differentiation and are partially sterile. We investigated how Csx1 is regulating this process in S. pombe. Csx1 associates with ste11+ mRNA and cells lacking Csx1 are sterile with a reduced amount of ste11+ mRNA. Overexpression of ste11+ mRNA completely rescues the mating deficiencies of csx1Δ cells. Here, we present a novel mechanism of ste11+ mRNA positive regulation through the activity of Csx1, an RNA binding protein that also have key functions in the response to oxidative stress in fission yeast. This finding opens interesting question about the possible coordination of sexual differentiation and oxidative stress response in eukaryotes and the role of RNA binding proteins in the adaptation to environmental signals.
NKAP Regulates Invariant NKT Cell Proliferation and Differentiation into ROR-γt–Expressing NKT17 Cells

Invariant NKT (iNKT) cells are a unique lineage with characteristics of both adaptive and innate lymphocytes, and they recognize glycolipids presented by an MHC class I–like CD1d molecule. During thymic development, iNKT cells also differentiate into NKT1, NKT2, and NKT17 functional subsets that preferentially produce cytokines IFN-γ, IL-4, and IL-17, respectively, upon activation. Newly selected iNKT cells undergo a burst of proliferation, which is defective in mice with a specific deletion of NKAP in the iNKT cell lineage, leading to severe reductions in thymic and peripheral iNKT cell numbers. The decreased cell number is not due to defective homeostasis or increased apoptosis, and it is not rescued by Bcl-xL overexpression. NKAP is also required for differentiation into NKT17 cells, but NKT1 and NKT2 cell development and function are unaffected. This failure in NKT17 development is rescued by transgenic expression of promyelocytic leukemia zinc finger; however, the promyelocytic leukemia zinc finger transgene does not restore iNKT cell numbers or the block in positive selection into the iNKT cell lineage in CD4-cre NKAP conditional knockout mice. Therefore, NKAP regulates multiple steps in iNKT cell development and differentiation.
Prevention of early-onset invasive neonatal group B streptococcal disease in a private hospital setting: the superiority of culture-based protocols.

OBJECTIVE In a large private tertiary care hospital we compared the two different approaches to group B streptococcal screening and intrapartum chemoprophylaxis suggested by The American College of Obstetricians and Gynecologists, the American Academy of Pediatrics, and the Centers for Disease Control and Prevention: risk factor-based protocol and culture-based protocol. STUDY DESIGN A 2-year baseline period was followed by sequential prospective observational studies of the impacts of two different group B streptococcal management protocols, 3 years with the risk-based approach and 2 years with the culture-based approach of universal screening at 35 to 37 weeks' gestation. RESULTS During the baseline period the rate of early-onset group B streptococcal infection was 1. 1 cases per 1000 births (n = 8 cases per 6829 births). With the risk-based strategy the rate was also 1.1 cases per 1000 births (15 cases/13,270 births). After we switched to the culture-based protocol for 2 years, there were no cases of early-onset group B streptococcal infections among 9304 births (P =.001; chi(2) = 10.9). There were no increases in other early-onset infections or in antibiotic resistance. CONCLUSIONS In our setting, which included good prenatal care and good communication between laboratories and the hospital, the approach based on maternal culture at 35 to 37 weeks' gestation and treatment during labor of all patients with positive results significantly reduced early-onset group B streptococcal infections without increasing infections from resistant organisms.
Lifestyle and dietary factors determine age at natural menopause

A literature search was done using PubMed. The age at natural menopause (ANM) depends on various factors like genetic, environmental, socioeconomic, reproductive, dietary, and lifestyle of which some like nulliparity, vegetarian diet, smoking, high fat intake, cholesterol, and caffeine accelerates; while others like parity, prior use of oral contraceptive pills, and Japanese ethnicity delays the ANM. ANM is an important risk factor for long-term morbidity and mortality; and hence, the need to identify the modifiable risk factors like diet and lifestyle changes. Delayed menopause is associated with increased risk of endometrial and breast cancer, while early ANM enhances the risk for cardiovascular diseases and osteoporosis. The correlation between diet and ANM has not been extensively studied; however, whatever studies have been done till now point towards role of high intake of total calories, fruits, and proteins in delaying the ANM, while high polyunsaturated fat intake accelerates it. The role of dietary soy, total fat, saturated fat, red meat, and dietary fiber in determining the ANM has been controversial and needs further studies to substantiate it. The lifestyle factors like current smoking and vigorous exercise have been significantly associated with early menopause, while moderate alcohol consumption delays the ANM. Large prospective studies are needed to study the association of ANM and other modifiable factors like passive smoking fish consumption, soy, and various types of tea. The knowledge of modifiable determinants of ANM can help in setting up menopausal clinics and initiating health programs specially in developing countries.
Support and conflict in ethnically diverse young adults’ relationships with parents and friends

We examined support and conflict with parents and close friends in a sample of ethnically diverse young adults (European-, Asian-, Cuban-, Latin-, and Mexican Americans). College students (N = 495) completed six subscales from the Network of Relationships Inventory (NRI; Furman & Buhrmester, 1985). Friends were rated higher than parents on global support by Asian- and European Americans, but not by the three Latino groups. Regardless of ethnic group, friends and parents provided different types of support, and conflict with parents was more frequent than conflict with friends. No differences due to age, gender, or generation of immigration emerged for European-, Cuban-, or Asian Americans; differences emerged attributable to gender among Mexican Americans (support and conflict), and generation of immigration among Latin Americans (support). Findings reveal ethnic group similarities in how college students’ social relationships are structured, but also highlight unique within-group experiences.
Sense of Belonging and Youth Suicidal Behaviors: What Do Communities and Schools Have to Do with It?

ABSTRACT Situating Thomas Joiner’s concept of belonging within an ecological perspective, this study examined the associations between school and community belonging and suicidal ideation and attempts among high school students. The study used data from the 2013 Texas Youth Risk Behavior Survey (N = 2,560). Results demonstrated that community belonging reduced the odds of youth suicidal behaviors. School bullying, feeling unsafe at school, and being threatened or injured at a school increased the odds of suicidal behaviors. Findings suggest that fostering safe and inclusive environments and strengthening youth’s experiences of school and community belonging may reduce suicidal behaviors in high school youth.
