Throughput Maximization for Decode-and-Forward Relay Channels With Non-Ideal Circuit Power

This paper studies the throughput maximization problem for a three-node relay channel with non-ideal circuit power. In particular, the relay operates in a half-duplex manner, and the decode-and-forward (DF) relaying scheme is adopted. Considering the extra power consumption by the circuits, the optimal power allocation to maximize the throughput of the considered system over an infinite time horizon is investigated. First, two special scenarios, i.e., the direct link transmission (only use the direct link to transmit) and the relay assisted transmission (the source and the relay transmit with equal probability) are studied, and the corresponding optimal power allocations are obtained. By transforming two non-convex problems into quasi-concave ones, the closed-form solutions show that the source and the relay transmit with certain probability, which is determined by the average power budgets, circuit power consumptions, and channel gains. Next, based on the above-mentioned results, the optimal power allocation for both the cases with and without direct link is derived, which is shown to be a mixed transmission scheme between the direct link transmission and the relay assisted transmission.
Evaluation of Fuel-Cell Range Extender Impact on Hybrid Electrical Vehicle Performance

The use of electric vehicles (EVs) is advantageous because of zero emission, but their market penetration is limited by one disadvantage, i.e., energy storage. Battery EVs (BEVs) have a limited range, and their batteries take a long time to charge, compared with the time it takes to refuel the tank of a vehicle with an internal combustion engine (ICE). Fuel cells (FCs) can be added to an EV as an additional energy source. These are faster to refill and will therefore facilitate the transition from vehicles running on fossil fuel to electricity. Different EV setups with FC strategies are presented and compared. The results of the setups are presented by range, efficiency, and price. These show the negative effect on the range when purpose-designed setups are driven above the design requirement as the range drops considerably. The simulations also showed the necessity of good FC control when driving in start/stop city cycles. Simulations with the New European Driving Cycle (NEDC) showed that efficiency fell by at least 15% for the FC hybrid EV (FCHEV) when compared with BEVs.
Optimal Algorithms for Assortment Selection Under Ranking-Based Consumer Choice Models

A retailer's product selection decisions are largely driven by her assumptions on how consumers make choices. We use a ranking-based consumer choice model to represent consumer preferences: every customer has a ranking of the potential products in the category and purchases his highest ranked product (if any) offered in the assortment. We consider four practically motivated special cases of this model, namely, the one-way substitution, the locational choice, the outtree, and the intree preference models, and we study the retailer's product selection problem when products have different price and cost parameters. We assume that the retailer incurs a fixed carrying cost per product offered, a goodwill penalty for each customer who does not purchase his first choice and a lost sale penalty for each customer who does not find an acceptable product to buy. For the first three models, we obtain efficient solution methods that simplify to either a shortest path method or a dynamic program. For the fourth model, we construct an effective algorithm and show numerically that, in practice, it is much faster than enumeration. We also obtain valuable insights on the structure of the optimal assortment.

However, there has been little attempt to understand how each type of processing relates to the other in behaving animals, despite their common substrate. In freely moving rats, there is a broadly linear relationship between hippocampal theta frequency and running speed over the normal range of speeds used during foraging. A recent model predicts that spatial-translation-related and arousal/anxiety-related mechanisms of hippocampal theta generation underlie dissociable aspects of the theta frequency–running speed relationship (the slope and intercept, respectively). Here we provide the first confirmatory evidence: environmental novelty decreases slope, whereas anxiolytic drugs reduce intercept. Variation in slope predicted changes in spatial representation by CA1 place cells and novelty-responsive behavior. Variation in intercept predicted anxiety-like behavior. Our findings isolate and doubly dissociate two components of theta generation that operate in parallel in behaving animals and link them to anxiolytic drug action, novelty, and the metric for self-motion.
Resting-state functional connectivity in neuropsychiatric disorders

Purpose of reviewThis review considers recent advances in the application of resting-state functional magnetic resonance imaging to the study of neuropsychiatric disorders. Recent findingsResting-state functional magnetic resonance imaging is a relatively novel technique that has several potential advantages over task-activation functional magnetic resonance imaging in terms of its clinical applicability. A number of research groups have begun to investigate the use of resting-state functional magnetic resonance imaging in a variety of neuropsychiatric disorders including Alzheimer's disease, depression, and schizophrenia. Although preliminary results have been fairly consistent in some disorders (for example, Alzheimer's disease) they have been less reproducible in others (schizophrenia). Resting-state connectivity has been shown to correlate with behavioral performance and emotional measures. It's potential as a biomarker of disease and an early objective marker of treatment response is genuine but still to be realized. SummaryResting-state functional magnetic resonance imaging has made some strides in the clinical realm but significant advances are required before it can be used in a meaningful way at the single-patient level.
Environmental Sensor Drift Correction using Wavelet-mFCM-FIS Architecture: An Unsupervised Machine Learning Approach

novel hybrid sensor informatics architecture based on Discrete Wavelet Transform (DWT), Fuzzy logic based clustering (FCM) and Fuzzy Rule based Inference system (FIS) has been investigated and proposed to estimate dynamic generic sensor drift during physical sampling. DWT has been used for sensor pre-processing; data dimension reduction and feature extraction from sensor time series, where as DWT- FCM based approach has been used to estimate the cumulative drift in our sensory system. An intelligent generalized algorithm using multiple FCM maps (m-FCM) has been proposed to implement the drift correction on any future unknown data sets. In the next stage a newly proposed DWT-FCM-FIS architecture has been tested on multisensory environmental data sets covering three consecutive years (2009 - 11) to predict probable month (environmental time of the year) with up to 93% accuracy. This novel hybrid data processing architecture have been implemented and tested upon a real time estuary sensory platform of temperature, conductivity and salinity sensors that have been deployed to monitor the Derwent Estuary in Hobart, Australia. This newly proposed approach could be an adaptive solution to tackle drifts in the sensor networks and improve overall monitoring quality.
Drug Use and Delinquent Behavior Among High Risk Youths

ABSTRACT We report the results of a study of substance use, measured by self-reports and hair test results, and delinquency among arrested youths entering a service intervention program. The results highlight important relationships between their alcohol and other drug use and involvement in delinquency in the year prior to their interviews. The research and service implications of these findings are discussed.
A Needs Assessment of Transgendered People of Color Living in Washington, DC

SUMMARY A needs assessment (N = 248) conducted in Washington, DC, revealed that trans-gendered people of color are at high risk for HIV/AIDS, substance abuse, suicide and violence/crime victimization. Overall HIV prevalence was 25%, with 32% in natal males (MTFs, i.e., male-to-females). Four predictors for HIV positive status were identified through logistic regression-male sex at birth, a history of substance abuse, sexual assault, and unemployment. Substance abuse was found in nearly half the sample (48%) but only half of those (51%) had sought treatment for it. Thirty-eight percent reported experiencing suicidal ideation, with 63% of those attributing it to their gender issues. Of those with suicidal ideation, nearly half (49%, or 16% of the entire sample), went on to make attempt(s) to kill themselves. Forty-three percent had been victims of violence or crime, including 13% who had been sexually assaulted. Knowledge of the Standards of Care of the Harry Benjamin International Gender Dysphoria Association was quite low (9%) and associated with white race, any higher education beyond high school, and access to sex reassignment surgery (SRS). Access to SRS, defined as obtaining vaginoplasties for natal males and chest surgeries for natal females, was just 4%. White race (versus all other races, p < .001) and female at birth (versus male, p < .01) were significantly associated with access to SRS. Use of hormones at some point during their lives was reported by 51% of participants. Thirty-five percent were currently taking hormones, with 72% acquiring their hormones from friends or on the street. Among natal males, 25% had injected silicone. Nineteen percent did not have their own living space, and employment, housing and job training were the most commonly-reported immediate needs of the sample. The results of this needs assessment provide evidence of an urgent need for increased medical and social services specific to transgendered people of color living in the District of Columbia.
Distribution of childhood leukaemias and non-Hodgkin's lymphomas near nuclear installations in England and Wales

Abstract Objective : To examine the relation between the risk of childhood leukaemia and non-Hodgkin's lymphoma and proximity of residence to nuclear installations in England and Wales. Design : Observed and expected numbers of cases were calculated and analysed by standard methods based on ratios of observed to expected counts and by a new statistical test, the linear risk score test, based on ranks and designed to be sensitive to excess incidence in close proximity to a putative source of risk. Setting : Electoral wards within 25 km of 23 nuclear installations and six control sites that had been investigated for suitability for generating stations but never used. Subjects : Children below age 15 in England and Wales, 1966-87. Main outcome measure - Registration of any leukaemia or non-Hodgkin's lymphoma. Results : In none of the 25 km circles around the installations was the incidence ratio significantly greater than 1.0. The only significant results for the linear risk score test were for Sellafield (P=0.00002) and Burghfield (P=0.031). The circles for Aldermaston and Burghfield overlap; the incidence ratio was 1.10 in each. One of the control sites gave a significant linear risk score test result (P=0.020). All the tests carried out were one sided with P values estimated by simulation. Conclusion : There is no evidence of a general increase of childhood leukaemia or non-Hodgkin's lymphoma around nuclear installations. Apart from Sellafield, the evidence for distance related risk is very weak.
Decoding and Fluency: Foundation Skills for Struggling Older Readers

A large number of secondary students read between the 2.5 and the 5.0 grade level. What separates many of these students from their higher performing peers is their inability to read multisyllabic words and to read fluently. These students need instruction in decoding long words using one of three approaches: reading segmented words part by part, decoding different syllable types, or using a flexible strategy for reading long words. These students also need sufficient reading practice to increase their reading rates. This practice might include oral guided reading, choral reading, partner reading, and/or repeated reading activities. The authors suggest that significant gains in reading are more likely to occur when teachers implement research-validated programs that have a well-designed sequence, provide systematic instruction to students, and furnish adequate practice.
Characterisation of a highly saturated Irvingia gabonensis seed kernel oil with unusual linolenic acid content

The search for new sources of oil with improved characteristics has focused our attention on the characterisation of Irvingia gabonensis seed kernel oil. Physicochemical analysis have revealed the following assets: refractive index (1.42 ± 0.00), free fatty acids (2.3 ± 0.8%), peroxide value (3.33 ± 0.57 meq O2/kg), iodine value (32.43 ± 1.22 g I2/100 g), saponification value (233.75 ± 2.60 mg KOH/g), unsaponifiable matter (1.5 ± 0.02%), carotenoids (63 ± 0.01 mg β-carotene/100 g) and phospholipids (2.1 ± 0.01%). Absorbance of this oil decreased abruptly in the range of UV-B and UV-A wavelengths. Gas chromatography analysis showed that the major fatty acids were saturated, being mainly composed of lauric (C12:0, 39.35 ± 0.01%) and myristic acids (C14:0, 20.54 ± 0.01%). Nevertheless, an unusually high amount (6.44 ± 0.02%) of linolenic acid was also noted. Mass spectrometer analysis of volatile compounds highlighted the presence of various aromatic and aliphatic organic compounds. I. gabonensis seed kernel oil also showed oxidative stability at 60 °C after 12 days of storage with maximum peroxide value of 34.66 meq O2/kg. In view of these interesting characteristics, I. gabonensis seed kernel could be used as an alternative source of oil for lipid industries.
Segmented Compressed Sampling for Analog-to-Information Conversion: Method and Performance Analysis

A new segmented compressed sampling (CS) method for analog-to-information conversion (AIC) is proposed. An analog signal measured by a number of parallel branches of mixers and integrators (BMIs), each characterized by a specific random sampling waveform, is first segmented in time into segments. Then the subsamples collected on different segments and different BMIs are reused so that a larger number of samples (at most ) than the number of BMIs is collected. This technique is shown to be equivalent to extending the measurement matrix, which consists of the BMI sampling waveforms, by adding new rows without actually increasing the number of BMIs. We prove that the extended measurement matrix satisfies the restricted isometry property with overwhelming probability if the original measurement matrix of BMI sampling waveforms satisfies it. We also prove that the signal recovery performance can be improved if our segmented CS-based AIC is used for sampling instead of the conventional AIC with the same number of BMIs. Therefore, the reconstruction quality can be improved by slightly increasing (by times) the sampling rate per each BMI. Simulation results verify the effectiveness of the proposed segmented CS method and the validity of our theoretical results. Particularly, our simulation results show significant signal recovery performance improvement when the segmented CS-based AIC is used instead of the conventional AIC with the same number of BMIs.
Undergraduate Students’ Experiences of an Integrated Psychiatric Nursing Curriculum in Korea

This qualitative study explored undergraduate nursing students’ experiences of an integrated psychiatric nursing curriculum in Seoul, Korea. Thirteen college students from the nursing school participated in focus-group interviews; the data were analyzed using content analysis. Four themes were derived: being confused by uncertainty, struggling to gain confidence, realizing humanity from stigma, and being motivated by role models. A conceptual model of psychiatric nursing education was developed based on these themes to explain the students’ developmental process from student nurse to psychiatric nurse. Psychiatric nurse educators must understand students’ learning process to facilitate their professional role identification.
FPTAS for Mixed-Strategy Nash Equilibria in Tree Graphical Games and Their Generalizations

We provide the first fully polynomial time approximation scheme (FPTAS) for computing an approximate mixed-strategy Nash equilibrium in tree-structured graphical multi-hypermatrix games (GMhGs). GMhGs are generalizations of normal-form games, graphical games, graphical polymatrix games, and hypergraphical games. Computing an exact mixed-strategy Nash equilibria in graphical polymatrix games is PPAD-complete and thus generally believed to be intractable. In contrast, to the best of our knowledge, we are the first to establish an FPTAS for tree polymatrix games as well as tree graphical games when the number of actions is bounded by a constant. As a corollary, we give a quasi-polynomial time approximation scheme (quasi-PTAS) when the number of actions is bounded by the logarithm of the number of players.
Comparative in-vitro activities of amoxycillin and penicillin against Streptococcus pneumoniae isolates.

Sir, In a recent issue of this Journal, Verhaegen & Verbist reported on the in-vitro activities of 21 -lactams against penicillin-susceptible and -resistant isolates of Strepto coccus pneumoniae. The results of this investigation are surprising because they suggest that amoxycillin is less active than penicillin against these strains. We have recently determined the in-vitro susceptibilities of 212 clinical isolates of S. pneumoniae by the microbroth dilution method according to recommendations of the National Committee for Clinical Laboratory Standards (NCCLS); the results are shown in the Table. The MICs of amoxycillin, in common with those of cefotaxime, were almost invariably one two-fold dilution lower than those of penicillin for strains with MICs of penicillin >0.06 mg/L. These observations in respect of pneumococci with reduced susceptibilities to penicillin are in accord with those of other investigators. In addition, Verhaegen & Verbist claimed that “Apart from penicillin, there are currently no NCCLS-approved breakpoints for oral -lactams for pneumococci. ” This is incorrect. In 1995, the NCCLS recommended MIC breakpoints for both oral amoxycillin (susceptible, 0.5 mg/L; intermediate susceptibility, 1 mg/L; and resistant, 2 mg/L) and co-amoxiclav (susceptible, 0.5/ 0.25 mg/L; intermediate susceptibility, 1/0.5 mg/L; and resistant, 2/ 1 mg/L). The fact that the susceptible and intermediate susceptibility breakpoints for amoxycillin are higher than those for penicillin (susceptible, 0.06 mg/L and intermediate susceptibility, 0.12–1 mg/L) reflect the superior pharmacokinetic profile of the former drug. This and its greater in-vitro activity explain why most pneumococci with reduced susceptibilities to penicillin remain fully susceptible or of intermediate susceptibility to amoxycillin, with or without clavulanic acid.
The development of conversation between mothers and babies

ABSTRACT The speech of two mothers to their infants at several points between three and eighteen months of age was analysed. Simplicity of the speech, as measured by MLU, was about the same at all ages, and none of the other features of the mothers' speech style showed any abrupt change at the time the children started to talk. The changes that did occur started much earlier, at about seven months. These findings are incompatible with the explanation that mothers speak simply and redundantly in response to cues of attention and comprehension from the child listener. It is suggested that the mothers interacted with their infants using a conversational model, and that the changes in the mothers' speech reflect their children's growing ability to function as conversational partners.
Implementation of E-health record systems in Australia

Consideration of e-health record systems in Australia started in 2000. Based on the effort to develop stand-alone and state-wide systems, the national Personally Controlled Electronic Health Record system was released on July 1, 2012. However this system has been widely criticised, although stakeholders are in favour of a national system. To overcome the challenges to the system and achieve its benefits, recommendations are provided for improving system effectiveness and usability, and adopting applicable government policies.
Epstein-Barr Virus LMP2A Reduces Hyperactivation Induced by LMP1 to Restore Normal B Cell Phenotype in Transgenic Mice

Epstein-Barr virus (EBV) latently infects most of the human population and is strongly associated with lymphoproliferative disorders. EBV encodes several latency proteins affecting B cell proliferation and survival, including latent membrane protein 2A (LMP2A) and the EBV oncoprotein LMP1. LMP1 and LMP2A signaling mimics CD40 and BCR signaling, respectively, and has been proposed to alter B cell functions including the ability of latently-infected B cells to access and transit the germinal center. In addition, several studies suggested a role for LMP2A modulation of LMP1 signaling in cell lines by alteration of TRAFs, signaling molecules used by LMP1. In this study, we investigated whether LMP1 and LMP2A co-expression in a transgenic mouse model alters B cell maturation and the response to antigen, and whether LMP2A modulates LMP1 function. Naïve LMP1/2A mice had similar lymphocyte populations and antibody production by flow cytometry and ELISA compared to controls. In the response to antigen, LMP2A expression in LMP1/2A animals rescued the impairment in germinal center generation promoted by LMP1. LMP1/2A animals produced high-affinity, class-switched antibody and plasma cells at levels similar to controls. In vitro, LMP1 upregulated activation markers and promoted B cell hyperproliferation, and co-expression of LMP2A restored a wild-type phenotype. By RT-PCR and immunoblot, LMP1 B cells demonstrated TRAF2 levels four-fold higher than non-transgenic controls, and co-expression of LMP2A restored TRAF2 levels to wild-type levels. No difference in TRAF3 levels was detected. While modulation of other TRAF family members remains to be assessed, normalization of the LMP1-induced B cell phenotype through LMP2A modulation of TRAF2 may be a pathway by which LMP2A controls B cell function. These findings identify an advance in the understanding of how Epstein-Barr virus can access the germinal center in vivo, a site critical for both the genesis of immunological memory and of virus-associated tumors.
