Zero-energy wake up for power line communications in smart cities

Street lighting is responsible for 6% of the greenhouse global gases emissions and for 19% of the total use of electrical energy; nevertheless it is essential for citizens safety in streets. The migration to smart lighting introduces the problem of power consumption of the intelligent infrastructure in standby mode, which was not present in classic lighting. In this paper, we show how to eliminate the power consumption in listening mode with power line communication (PLC) infrastructure, adding zero-power wakeup receivers to the modems. This promising solution can be extended as a general technology for monitoring and controlling in a smart grid distribution. We show the design of the different hardware sections and, supported by simulations and experimental results, we discuss some considerations about the most efficient configurations and the best routing to wake up a remote PLC modem with the minimum power.
MLL repression domain interacts with histone deacetylases, the polycomb group proteins HPC2 and BMI-1, and the corepressor C-terminal-binding protein

The MLL (mixed-lineage leukemia) gene is involved in many chromosomal translocations associated with acute myeloid and lymphoid leukemia. We previously identified a transcriptional repression domain in MLL, which contains a region with homology to DNA methyltransferase. In chromosomal translocations, the MLL repression domain is retained in the leukemogenic fusion protein and is required for transforming activity of MLL fusion proteins. We explored the mechanism of action of the MLL repression domain. Histone deacetylase 1 interacts with the MLL repression domain, partially mediating its activity; binding of Cyp33 to the adjacent MLL-PHD domain potentiates this binding. Because the MLL repression domain activity was only partially relieved with the histone deacetylase inhibitor trichostatin A, we explored other protein interactions with this domain. Polycomb group proteins HPC2 and BMI-1 and the corepressor C-terminal-binding protein also bind the MLL repression domain. Expression of exogenous BMI-1 potentiates MLL repression domain activity. Functional antagonism between Mll and Bmi-1 has been shown genetically in murine knockout models for Mll and Bmi-1. Our new data suggest a model whereby recruitment of BMI-1 to the MLL protein may be able to modulate its function. Furthermore, repression mediated by histone deacetylases and that mediated by polycomb group proteins may act either independently or together for MLL function in vivo.
The Bilingual Lexicon

In this chapter we examine how bilinguals recognize and speak words in each of their two languages. First, we review the way in which available models of the bilingual lexicon reflect different assumptions about the architecture and processing of words in two languages. Next, we consider three central questions about lexical access in bilinguals: (1) What codes are activated? ; (2) When are these codes activated? ; and (3) What are the critical factors that affect lexical selection? We examine the answers to these questions first for comprehension and then for production. Because we assume that comprehension and production rely on a common representational system but differ in the problems that they pose for the system, we finally consider the implications of the comparison for reaching general conclusions about the nature of the bilingual lexicon.
Androgens and spermatogenesis: lessons from transgenic mouse models

Transgenic mouse models have contributed considerably to our understanding of the cellular and molecular mechanisms by which androgens control spermatogenesis. Cell-selective ablation of the androgen receptor (AR) in Sertoli cells (SC) results in a complete block in meiosis and unambiguously identifies the SC as the main cellular mediator of the effects of androgens on spermatogenesis. This conclusion is corroborated by similar knockouts in other potential testicular target cells. Mutations resulting in diminished expression of the AR or in alleles with increased length of the CAG repeat mimick specific human forms of disturbed fertility that are not accompanied by defects in male sexual development. Transcriptional profiling studies in mice with cell-selective and general knockouts of the AR, searching for androgen-regulated genes relevant to the control of spermatogenesis, have identified many candidate target genes. However, with the exception of Rhox5, the identified subsets of genes show little overlap. Genes related to tubular restructuring, cell junction dynamics, the cytoskeleton, solute transportation and vitamin A metabolism are prominently present. Further research will be needed to decide which of these genes are physiologically relevant and to identify genes that can be used as diagnostic tools or targets to modulate the effects of androgens in spermatogenesis.
How task demands influence time-based prospective memory performance in young and older adults

Prospective memory performance as a measure of everyday cognitive functioning is of increasing importance for developmental research. However, comparisons of studies on prospective memory development in adults reveal essential differences. Although some studies report no age effects, others find age effects of widely varying magnitudes. We suggest that differences in these findings on prospective memory performance can be explained by an age by task interaction (i.e., large amounts of cognitive load imposed by time-based prospective memory tasks disproportionally penalise older adults who possess fewer cognitive resources). We explored our hypothesis in a study with 90 young adults (M = 24.0 years) and 75 older adults (M = 69.0 years) by manipulating the overall cognitive processing demands of the prospective task situation. We varied the cognitive load of the background task while holding constant the time-based prospective memory task. Results indicate that the effects of increased overall processing demands strongly influence older adults’ performance. Results are discussed within the framework of capacity explanations of cognitive ageing that focus on the role of working memory resources in monitoring processes.

Perilipin A Increases Triacylglycerol Storage by Decreasing the Rate of Triacylglycerol Hydrolysis*

The perilipins are the most abundant proteins at the surfaces of lipid droplets in adipocytes and are also found in steroidogenic cells. To investigate perilipin function, perilipin A, the predominant isoform, was ectopically expressed in fibroblastic 3T3-L1 pre-adipocytes that normally lack the perilipins. In control cells, fluorescent staining of neutral lipids with Bodipy 493/503 showed a few minute and widely dispersed lipid droplets, while in cells stably expressing perilipin A, the lipid droplets were more numerous and tightly clustered in one or two regions of the cytoplasm. Immunofluorescence microscopy revealed that the ectopic perilipin A localized to the surfaces of the tiny clustered lipid droplets; subcellular fractionation of the cells using sucrose gradients confirmed that the perilipin A localized exclusively to lipid droplets. Cells expressing perilipin A stored 6–30-fold more triacylglycerol than control cells due to reduced lipolysis of triacylglycerol stores. The lipolysis of stored triacylglycerol was 5 times slower in lipid-loaded cells expressing perilipin A than in lipid-loaded control cells, when triacylglycerol synthesis was blocked with 6 μm triacsin C. This stabilization of triacylglycerol was not due to the suppression of triacylglycerol lipase activity by the expression of perilipin A. We conclude that perilipin A increases the triacylglycerol content of cells by forming a barrier that reduces the access of soluble lipases to stored lipids, thus inhibiting triacylglycerol hydrolysis. These studies suggest that perilipin A plays a major role in the regulation of triacylglycerol storage and lipolysis in adipocytes.
The Absence of Practice Effects on a Forced-Choice Temporal Order Judgment Task

Abstract The encoding of temporal order information improves with practice (Zacks, Hasher, Alba, Sanft, & Rose, 1984), but this improvement may be a result of task performance factors and may have little or nothing to do with encoding phenomena. In the present study, a forced-choice recency discrimination procedure was used to obviate the use of retrieval/performance strategies on the temporal order test. No improvement in temporal order judgments was observed.
Including Students with Severe Disabilities in General Education Settings

A number of social, judiciary, and regulatory policies are intended to change current educational practices. Educational change, however, does not automatically occur as a result of policy adoption. Rather, educational change occurs as a result of leaders employing systematic procedures to bring about these changes. A growing philosophical, legal, and empirical data base supports the inclusion of students with severe disabilities in general education settings. This paper presents guidelines intended for educational leaders in effecting the change from segregated to inclusive school settings. Five systematic phases, or guidelines, are presented. In order to bring about successful inclusion of students with severe disabilities, leaders develop networks, assess resources, review options, install inclusion strategies, and provide a system of feedback and self-renewal.
Psychosocial safety climate moderating the effects of daily job demands and recovery on fatigue and work engagement

This study examined the role of schools’ psychosocial safety climate (PSC) in teachers’ psychological outcomes.We proposedthat PSCwouldmoderate the effectsofteachers’ daily job demands on their fatigue and work engagement, and also the effects of teachers’ daily recovery onfatigue and engagement. Sixty-one Australian school teachers completed a diary that was repeated three times over the course of approximately 8 months. Each diary ran for five consecutive days, measuring daily self-reports of job demands, recovery, fatigue, and engagement (N = 915 data points), while perceived PSC was measured once per diary. Multilevel analyses indicated that PSC moderated the relationships between job demands and fatigue, as well as job demands and engagement. This suggests that perceived PSC could act as a buffer against deleterious impacts of daily job demands. PSC also moderated the relationships between recovery and fatigue, and recovery and engagement. This indicates that higher levels of perceived PSC in schools couldamplifythebenefitsofdailyrecoveryforteachers.PSCalsoexertedamaineffecton both fatigue and engagement. These results offer insight into the mechanisms by which PSCmayactasabuffertoprotectworkermentalhealth,andhighlighttheimportancefor school management to promote PSC within their organization.

Monthly Precipitation Patterns in a Region Vulnerable to Climate-Related Hazards—A Case Study from Poland

Precipitation totals at annual and monthly scale are key elements affecting water availability for a number of human activities. Thus, the multi-year variability and probability distribution of precipitation form the basis information for water management and damage risk assessment (caused by drought and heavy rains). The main goal of this paper is to analyse the precipitation patterns and to determine the non-exceedance probability (p, %) of extreme monthly precipitation in the region influenced by lignite mining and dominated by traditional agricultural production. Monthly precipitation totals recorded in 1961–2010 at four weather stations close to the analysed region were examined, including comparative analysis of precipitation patterns between the stations. Different non-exceedance probability (p, %) was determined with focus on extreme precipitation. Annual and monthly precipitation was characterised by a large variation of values. Temporal variability was larger than the spatial variability. The highest average sums were registered in July and the lowest in February. Minimum monthly precipitation (<10 mm) were recorded between January and April, and in October at all four weather stations. Maximum totals, amounting to more than 200 mm, were noted in July. The largest share of absolute minimum and maximum monthly precipitation was recorded at the turn of 20th and 21st centuries. Temporal and spatial distribution of precipitation for very dry, abnormally dry and extremely dry months (p ≤ 20%) were characterised by lower dispersion of values compared with wet months (p ≥ 80%). The precipitation probability distribution at p ≤ 20% may be useful to determine agricultural drought risk assessment in the region. Monthly precipitation at p ≥ 80% may be the background for planning drainage system efficiency and assessment of flooding risk of lignite deposits.
Contribution of visual and proprioceptive system to the limit of stability in geriatric population – An observational study

Abstract Background: Balance is needed to maintain stability during a quiet or pertubated stance. The ability to balance can be compromised by the biological process of aging. Impairment of this ability ultimately results in increased morbidity, mortality, healthcare cost or can lead to a fear for one's safety with a self-imposed limitation of activity. However, there is no argument regarding the role of the sensory system to maintain balance, but conflict still exists regarding its underlying contribution. Purpose: To determine the way the visual and proprioceptor systems contributes to maintaining balance and determine the alteration of contribution by those systems regarding gender, age, height and weight. Methods: Sixty participants of more than 60 years of age were selected randomly. Participants were assessed by a multidirectional reach test on a firm, foam surface and a ball with open and closed eyes on each surface. Results: A visual and proprioceptive contribution of 11.69% and 22.56%, respectively, was found on a firm surface and there was significant change in the contribution depending on the surface. Discussion: We suggested that vision is less able to supplement peripheral input to maintain balance compared with the proprioceptive system. Conclusion: The proprioceptive system contributes more compared with the visual system for postural stability. As the demand increases because of altered environments, the contribution from those systems also increases.
Transcription of essential cell division genes is linked to chromosome replication in Escherichia coli

Cell division normally follows the completion of each round of chromosome replication in Escherichia coli. Transcription of the essential cell division genes clustered at the mra region is shown here to depend on continuing chromosomal DNA replication. After chromosome replication was blocked by either nalidixic acid treatment or thymine starvation, the transcription of these cell division genes was repressed significantly. This suggests a way in which cell division is controlled by chromosome replication.
Management applications of analyzing cellular digital packet data (CDPD) billing data

This paper investigates the management applications of analyzing CDPD billing data. Using three non-contiguous weeks of data, we demonstrate how to extract usage patterns, detect registration idiosyncrasies and network faults, and chart the impact of signing roaming agreements with other carriers. We describe the fields available in billing data and how to collect parameters of interest with these fields. Demonstrating how to extract usage parameters, we graph the number of successful registrations and packets transmitted on a temporal and geographical basis. We detail an approach to detect and locate faults resulting in discarded packets. We describe the difficulties in detecting mobility patterns. The impact of foreign mobiles on a network is also explored. Further research into the analysis of billing data will help both researchers and service providers learn about their current implementations and plan future networks.
Psychosocial and Physical Impact of Chronic Fatigue in a Community-Based Sample of Children and Adolescents

AbstractBackground: Few studies have examined the problem of chronic fatigue in children and adolescents and its potential impact on functioning. Chronic fatigue may have a negative impact on school functioning, family activities, psychological well-being, physical functioning, and severity of medical symptomatology.Objectives: This study compared psychosocial, family, and physical functioning between a randomly selected community based sample of 36 children and adolescents with chronic fatigue and a group of 21 children and adolescents without fatigue.Methods: Children and parents completed a comprehensive medical history questionnaire and questionnaires assessing psychological functioning, family functioning, and school attendance.Results: Results indicated that children with chronic fatigue tended to have more difficulties in overall physical and psychological functioning, as measured by the Child Health Questionnaire and the Child Behavior Checklist. In addition, children in the chronic fatigue group .
Web services access control architecture incorporating trust

Purpose – This paper seeks to investigate how the concept of a trust level is used in the access control policy of a web services provider in conjunction with the attributes of users.Design/methodology/approach – A literature review is presented to provide background to the progressive role that trust plays in access control architectures. The web services access control architecture is defined.Findings – The architecture of an access control service of a web service provider consists of three components, namely an authorisation interface, an authorisation manager, and a trust manager. Access control and trust policies are selectively published according to the trust levels of web services requestors. A prototype highlights the incorporation of a trust level in the access control policy as a viable solution to the problem of web services access control, where decisions of an autonomous nature need to be made, based on information and evidence.Research limitations/implications – The WSACT architecture addr.
A Reinterpretation of Parental Monitoring in Longitudinal Perspective

A commonly used measure of parental monitoring is parents' knowledge of adolescents' daily activities. This measure has been criticized on the grounds that parents get more knowledge about teenagers' daily activities through willing youth disclosure than through their own active monitoring efforts, but this claim was based on cross-sectional data. In the present study, we reexamine this claim with longitudinal data over 2 years from 938 seventh and eighth graders and their parents. Youth disclosure was a significant longitudinal predictor of parental knowledge in single- and cross-rater models. Neither measure of parents' monitoring efforts—control or solicitation—was a significant predictor. In analyses involving delinquency, parental monitoring efforts did not predict changes in delinquency over time, but youth disclosure did. We conclude that because knowledge measures do not seem to represent parental monitoring efforts, the conclusions from studies using these measures should be reinterpreted.
Customs of Governance: Colonialism and Democracy in Twentieth Century India

‘Who is stealing electricity’ at Tis Hazari? —the principal magistrate's court for the city of Delhi. The mystery, it turned out, had a simple solution. It implicated a large proportion of the 1500 lawyers' chambers in the court buildings. According to the Vice-President of the Delhi Bar Association (Criminal), the problem arose because the Delhi Vidyut Board ‘had installed electricity junction boxes in the premises and has not given any regular connection to individual chambers. Hence, most lawyers had to make their own arrangements’. By this, he meant that the lawyers resorted to tapping electricity from the board's supply lines to run their lights and fans, their refrigerators, air-conditioners and computers. Speaking on behalf of the criminal lawyers, and lending a certain adjectival force to their professional description, their Vice President admitted that it was true that ‘earlier, we were stealing electricity. … But now we have taken up the matter with the DVB and have shown our eagerness in seeking regularised connections’. It was almost as if he expected that their eagerness could be entered as a plea in mitigation.
Cardiovascular risk of patients with gout seen at rheumatology clinics following a structured assessment

Objectives Gout-associated cardiovascular (CV) risk relates to comorbidities and crystal-led inflammation. The aim was to estimate the CV risk by prediction tools in new patients with gout and to assess whether ultrasonographic carotid changes are present in patients without high CV risk. Methods Cross-sectional study. Consecutive new patients with crystal-proven gout underwent a structured CV consultation, including CV events, risk factors and two risk prediction tools—the Systematic COronary Evaluation (SCORE) and the Framingham Heart Study (FHS). CV risk was stratified according to current European guidelines. Carotid ultrasound (cUS) was performed in patients with less than very high CV risk. The presence of carotid plaques was studied depending on the SCORE and FHS by the area under the curve (AUC) of receiver operating curves. Results 237 new patients with gout were recruited. CV stratification by scores showed a predominance of very high (95 patients, 40.1%) and moderate (72 patients, 30.5%) risk levels. cUS was performed in 142 patients, finding atheroma plaques in 66 (46.5%, 95% CI 37.8 to 54.2). Following cUS findings, patients classified as very high risk increased from 40.1% up to 67.9% (161/237 patients). SCORE and FHS predicted moderately (AUC 0.711 and 0.683, respectively) the presence of atheroma plaques at cUS. Conclusions The majority of patients presenting with gout may be at very high CV risk, indicating the need for initiating optimal prevention strategies at this stage. Risk prediction tools appear to underestimate the presence of carotid plaque in patients with gout.
