Performance Analysis of Relay Assisted Cooperative Non-Orthogonal Multiple Access Systems

Non-orthogonal multiple access (NOMA) is a promising multiple access technique for the fifth generation (5G) wireless communications. In order to enhance the performance gains of NOMA systems, a relay assisted cooperative NOMA scheme is designed in this paper. In the proposed scheme, the concept of NOMA is exploited to realize the transmission of the source information in the second time slot. The destination can only receives a single data symbol in conventional cooperative systems, while the destination can reliably acquire two data symbols in two time slots. Therefore, the proposed scheme can achieve higher achievable rate performance than existing schemes. Moreover, the complex power allocation algorithm can be avoided to alleviate the complexity of cooperative NOMA systems. For Rayleigh fading channels, we derive exact expressions for two important performance metrics of the proposed scheme, i.e., the outage probability and the achievable rate. In addition, asymptotic results are presented in terms of simple elementary functions to provide useful insights to guide the practical implementation. Monte-Carlo simulations are provided to demonstrate the performance of the proposed scheme and the accuracy of the derived analytical results.
Is Trust the Most Important Human Factor Influencing Knowledge Sharing in Organisations?

The present study explores several of the most significant social and cognitive human factors that have been found to motivate or inhibit organisational knowledge sharing in previous empirical studies. Of specific interest is the individual and collective effect that trust, shared language, shared vision, tie strength, homophily and relationship length have on three important conditions necessary for effective knowledge sharing to take place (i.e. willingness to share, willingness to use and perceived receipt of useful knowledge). The study also considers the nature of the employee working relationship (positive versus negative) and the form of knowledge sharing (explicit versus tacit). In total, 275 surveys were completed by employees working on projects at one of Canada's largest multijurisdictional law firms. Quantitative methods were used to examine the relationships between the dependent variables and independent variables, while controlling for all the other variables in the model.
IMPACT OF HEALTH EDUCATION PROGRAM ON KNOWLEDGE ABOUT AIDS AND HIV TRANSMISSION IN STUDENTS OF SECONDARY SCHOOLS IN BURAIDAH CITY, SAUDI ARABIA: AN EXPLORATORY STUDY

Background: Accurate information about Acquired Immunodeficiency Syndrome (AIDS) and Human Immunodeficiency Virus (HIV) is important for their prevention. Objectives: This study is intended to assess knowledge on AIDS in students of secondary schools in Buraidah city and to measure the effect of a health education program on their knowledge about AIDS in general, modes of HIV transmission and the degree of their misperception about the transmission of the disease through casual contact. Methodology: A well-designed health education program using personal communication and visual media techniques was conducted for 483 secondary school students in Buraidah secondary schools during the year 1997. Pre and post-tests were done to examine their knowledge about AIDS. Results and recommendations: The results of this study pointed out that a health education program on AIDS for students of secondary schools greatly and significantly improved their scores on general knowledge on AIDS views on its transmission and misperception of AIDS (p<0.01). Continuous in-service programs for secondary students are recommended.

Factors influencing vaginal cytology, pH and bacterial flora in elderly women

Objective. To evaluate factors influencing the vaginal micro‐environment in elderly women. Study design. Vaginal pH, cytology (Karyopyknotic index, KPI) and bacterial cultures were assessed in 350 women (age 72.2 ± 1.4 years, range 65–84 years) who were not taking estrogens. Results. Vaginal pH was 6.5 ± 0.1, KPI was 3.0 ± 0.9% and bacteria of fecal type dominated. However, in some women the vaginal micro‐environment resembled that of fertile women, with a predominance of laclobacilli (n = 68), low pH (n = 41) and an increased maturation index (n = 57). KPI was higher (p > 0.001) in women weighing ≥ 85 kg, or with a body mass ≥ 9th decentile or with a diastolic blood pressure ≥ 100 mmHg and in women (p > 0.05) with a high menopausal age (≥ 53 years). Vaginal pH was lower (p > 0.001), KPI was higher (p > 0.01) and there was an increased (p >0.05) presence of lactobacilli in smokers compared to non‐smokers.
PIPS one Advances in Quantitative Hepcidin Measurements by Time-of-Flight Mass Spectrometry

Assays for the detection of the iron regulatory hormone hepcidin in plasma or urine have not yet been widely available, whereas quantitative comparisons between hepcidin levels in these different matrices were thus far even impossible due to technical restrictions. To circumvent these limitations, we here describe several advances in time-of flight mass spectrometry (TOF MS), the most important of which concerned spiking of a synthetic hepcidin analogue as internal standard into serum and urine samples. This serves both as a control for experimental variation, such as recovery and matrix-dependent ionization and ion suppression, and at the same time allows value assignment to the measured hepcidin peak intensities. The assay improvements were clinically evaluated using samples from various patients groups and its relevance was further underscored by the significant correlation of serum hepcidin levels with serum iron indices in healthy individuals. Most importantly, this approach allowed kinetic studies as illustrated by the paired analyses of serum and urine samples, showing that more than 97% of the freely filtered serum hepcidin can be reabsorbed in the kidney. Thus, the here reported advances in TOF MS-based hepcidin measurements represent critical steps in the accurate quantification of hepcidin in various body fluids and pave the way for clinical studies on the kinetic behavior of hepcidin in both healthy and diseased states.

Acetylcholine–dopamine balance hypothesis in the striatum: An update

The imbalance between cholinergic activity and dopaminergic activity in the striatum causes a variety of neurological disorders, such as Parkinson's disease. During sensorimotor learning, the arrival of a conditioned stimulus reporting a reward evokes a pause response in the firing of the tonically active cholinergic interneurons in targeted areas of the striatum, whereas the same stimulus triggers an increase in the firing frequency of the dopaminergic neurons in the substantia nigra pars compacta. The pause response of the cholinergic interneurons begins with an initial depolarizing phase followed by a pause in spike firing and ensuing rebound excitation. The timing of the pause phase coincides well with the surge in dopaminergic firing, indicating that a dramatic rise in dopamine (DA) release occurs while nicotinic receptors remain unbound by acetylcholine. The pause response begins with dopamine D5 receptor‐dependent synaptic plasticity in the cholinergic neurons and an increased GABAergic IPSP, which is followed by a long pause in firing through D2 and D5 receptor‐dependent modulation of ion channels. Inactivation of muscarinic receptors on the projection neurons eventually yields endocannabinoid‐mediated, dopamine‐dependent long‐term depression in the medium spiny projection neurons. Breakdown of acetylcholine‐dopamine balance hampers proper functioning of the cortico‐basal ganglia‐thalamocortical loop circuits. In Parkinson's disease, dopamine depletion blocks autoinhibition of acetylcholine release through muscarinic autoreceptors, leading to excessive acetylcholine release which eventually prunes spines of the indirect‐pathway projection neurons of the striatum and thus interrupts information transfer from motor command centers in the cerebral cortex.

Combination of hyperbaric lidocaine and ropivacaine in spinal anaesthesia for day surgery

Background and objective: Motor function recovers rapidly but the extended duration of sensory block after spinal anaesthesia with hyperbaric ropivacaine may delay patients' ambulation after surgery. We tested whether compensating a reduction of the ropivacaine dose with a small dose of lidocaine would be adequate for surgery and shorten recovery from spinal anaesthesia. Methods: Fifty‐six consecutive outpatients, who were scheduled for lower extremity surgery under spinal anaesthesia, were randomized into two groups to receive either a hyperbaric solution of lidocaine 20 mg and ropivacaine 5 mg (Group LR) or hyperbaric ropivacaine 10 mg (Group R). Sensory block was tested with pinprick and motor block on the Bromage scale at 5‐min intervals until 30 min, then at 15‐min intervals until 90 min, and thereafter at 30‐min intervals until full bilateral recovery. Blinded interviews were performed on the first and seventh postoperative day. Results: The groups did not differ significantly regarding success of sensory block reaching T10 dermatome on the operative side, 24 (86%) in Group LR and 23 (82%) in Group R, median (range) onset time 5 (5–20) vs. 10 (5–25) min or median duration of T10 sensory block 68 (5–115) vs. 50 (20–115) min, respectively. Two patients in each group required general anaesthesia. Recovery did not differ between the groups, median time of full motor recovery was 75 min in both groups, sensory recovery of S2 2.5 h vs. 2.8 h, first voluntary micturition 4.2 (2.2–6.1) vs. 4.5 (2.4–6.6) h in the LR vs. R Group, respectively. Transient neurological symptoms did not appear. Conclusion: It is concluded that spinal anaesthesia with hyperbaric lidocaine 20 mg + ropivacaine 5 mg and hyperbaric ropivacaine 10 mg was quite similar regarding frequency, onset, duration of T10 dermatome sensory block and recovery. The patients would have been ready for discharge after voluntary micturition, 4.2–4.5 h from the subarachnoid injection of local anaesthetics.
Patterns of Eye Movements When Observers Judge Female Facial Attractiveness

The purpose of the present study is to explore the fixed model for the explicit judgments of attractiveness and infer which features are important to judge the facial attractiveness. Behavioral studies on the perceptual cues for female facial attractiveness implied three potentially important features: averageness, symmetry, and sexual dimorphy. However, these studies did not explained which regions of facial images influence the judgments of attractiveness. Therefore, the present research recorded the eye movements of 24 male participants and 19 female participants as they rated a series of 30 photographs of female facial attractiveness. Results demonstrated the following: (1) Fixation is longer and more frequent on the noses of female faces than on their eyes and mouths (no difference exists between the eyes and the mouth); (2) The average pupil diameter at the nose region is bigger than that at the eyes and mouth (no difference exists between the eyes and the mouth); (3) the number of fixations of male participants was significantly more than female participants. (4) Observers first fixate on the eyes and mouth (no difference exists between the eyes and the mouth) before fixating on the nose area. In general, participants attend predominantly to the nose to form attractiveness judgments. The results of this study add a new dimension to the existing literature on judgment of facial attractiveness. The major contribution of the present study is the finding that the area of the nose is vital in the judgment of facial attractiveness. This finding establish a contribution of partial processing on female facial attractiveness judgments during eye-tracking.
The Prediction of Rehabilitative Success after Three Years the use of Social, Symptom and Cognitive Variables

A three-year follow-up study of 49 psychiatric patients, representative of those found in long-stay care, tested whether behavioural, symptom and demographic variables as well as response-processing difficulties could predict levels of psychiatric care. The researchers were blind to the criteria for allocating patients to particular forms of care and the staff responsible for care had no access to information collected by the research team. Not only was it possible, using only these few factors, to predict the form of care, but one factor, response processing, was related to whether patients moved to more independent forms of psychiatric care.
Diversity and genomics of Antarctic marine micro-organisms

Marine bacterioplanktons are thought to play a vital role in Southern Ocean ecology and ecosystem function, as they do in other ocean systems. However, our understanding of phylogenetic diversity, genome-enabled capabilities and specific adaptations to this persistently cold environment is limited. Bacterioplankton community composition shifts significantly over the annual cycle as sea ice melts and phytoplankton bloom. Microbial diversity in sea ice is better known than that of the plankton, where culture collections do not appear to represent organisms detected with molecular surveys. Broad phylogenetic groupings of Antarctic bacterioplankton such as the marine group I Crenarchaeota, α-Proteobacteria (Roseobacter-related and SAR-11 clusters), γ-Proteobacteria (both cultivated and uncultivated groups) and Bacteriodetes-affiliated organisms in Southern Ocean waters are in common with other ocean systems. Antarctic SSU rRNA gene phylotypes are typically affiliated with other polar sequences. Some species such as Polaribacter irgensii and currently uncultivated γ-Proteobacteria (Ant4D3 and Ant10A4) may flourish in Antarctic waters, though further studies are needed to address diversity on a larger scale. Insights from initial genomics studies on both cultivated organisms and genomes accessed through shotgun cloning of environmental samples suggest that there are many unique features of these organisms that facilitate survival in high-latitude, persistently cold environments.
Intracellular localization and DNA-binding properties of human papillomavirus type 18 E6 protein expressed with a baculovirus vector

The E6 protein of human papillomavirus type 18 (HPV-18) is a putative zinc-finger protein that is expressed in HPV-18-induced genital neoplasias. We have studied the biochemical properties of E6 protein synthesized in large amounts with a baculovirus expression vector. When E6 protein was synthesized in insect cells infected with an E6-expressing baculovirus, the protein was localized to both nuclear and membrane fractions, with half-lives of 4 and 2 h, respectively. Changing the first five amino acids of E6 did not alter the pattern of cellular localization of the protein but dramatically increased the half-life of the nuclear component to longer than 30 h and increased the half-life of the membrane component to 8 h. Although the baculovirus-expressed E6 protein bound to double-stranded DNA with high affinity, no sequence specificity for HPV-18 DNA was detected.
Planning for Future Care Needs: Experiences of Unmarried Heterosexual and Sexual Minority Women

This study examined the experiences of legally unmarried, middle-aged and older sexual minority (e.g., lesbian, bisexual) and heterosexual women in planning for future care needs and long-term assistance. A total of 215 women (90 sexual minority women and 125 heterosexual women) 41–78 years of age completed a survey about long-term care planning strategies, including: (1) executing a will; (2) naming a health care proxy; (3) purchasing long-term care insurance; and (4) discussing potential living arrangements with at least one family member. Overall, 18.5% of women reported completing zero of the strategies, and 3.4% reported completing all four. Over half (59%) had completed at least two strategies. Women were most likely to have executed a will (68%) and named a health care proxy (61%). Both sexual minority women and heterosexual women were most likely to have talked to a family member of choice, rather than a biological family member about living with them if they were unable to care for themselves. Currently, serving as a health care proxy was an important correlate for having made long-term care plans and was particularly important for sexual minority women. Women who are not in traditional marriage relationships tend to adopt long-term care planning strategies that legally clarify and establish the nature of their important relationships.
Denoising Prior Driven Deep Neural Network for Image Restoration

Deep neural networks (DNNs) have shown very promising results for various image restoration (IR) tasks. However, the design of network architectures remains a major challenging for achieving further improvements. While most existing DNN-based methods solve the IR problems by directly mapping low quality images to desirable high-quality images, the observation models characterizing the image degradation processes have been largely ignored. In this paper, we first propose a denoising-based IR algorithm, whose iterative steps can be computed efficiently. Then, the iterative process is unfolded into a deep neural network, which is composed of multiple denoisers modules interleaved with back-projection (BP) modules that ensure the observation consistencies. A convolutional neural network (CNN) based denoiser that can exploit the multi-scale redundancies of natural images is proposed. As such, the proposed network not only exploits the powerful denoising ability of DNNs, but also leverages the prior of the observation model. Through end-to-end training, both the denoisers and the BP modules can be jointly optimized. Experimental results on several IR tasks, e.g., image denoisig, super-resolution and deblurring show that the proposed method can lead to very competitive and often state-of-the-art results on several IR tasks, including image denoising, deblurring, and super-resolution.
Seeking security in the New Age: On attachment and emotional compensation

The purpose of the present cross-sectional questionnaire study was to construct a comprehensive and reliable scale to assess new age orientation as a continuous individual difference variable. Given large increases in new age orientation in Sweden in recent years, an additional purpose was to test our emotional compensation hypothesis by studying connections of retrospective parental and adult romantic attachment in relation to new age orientation, emotionally-based religiosity, and socialization-based religiosity, as well as to study links between attachment and several aspects of spiritual change. The study group included 193 participants from upper secondary school classes, Christian youth organizations, and new age establishments in Stockholm, Sweden. The new age orientation scale was shown to be unidimensional according to an exploratory factor analysis, and to possess adequate reliability and construct validity. In line with the emotional compensation predictions, new age orientation was directly linked to attachment insecurity and emotionally-based religiosity and inversely related to socialization-based religiosity. Attachment insecurity was also linked to the experience of spiritual changes, whereas most findings pertaining to characteristics of spiritual change did not support predictions. In general, unlike perceived attachment to parents, adult romantic attachment did not display the predicted pattern of results. It was concluded that attachment theory may make an important contribution by highlighting predisposing factors for new age orientation, as representing one aspect of the emotional compensation profile, but that several methodological improvements are necessary in future studies.
Cerebellothalamic projections in the rat: An autoradiographic and degeneration study

The purpose of this study was to determine the topographical organization of cerebellothalamic projections in the rat. Following stereotaxic injections of 3H‐leucine or electrolytic lesions in the cerebellar nuclei, efferent fibers were observed to emerge from the cerebellum through two discrete routes. Fibers from the fastigial nucleus decussated within the cerebellum, formed the crossed ascending limb of the uncinate fasciculus, ascended in the dorsal part of the midbrain tegmentum, and entered the thalamus. Cerebellothalamic fibers from the interpositus and dentate nuclei coursed in the ipsilateral brachium conjuctivum, decussated in the caudal midbrain, and ascended to the thalamus via the crossed ascending limb of the brachium conjunctivum.
ASCORBIC ACID;

Objectives: To demonstrate the volume changes that are produced byanthracycline Doxorubicin DOX on the testes of mice and designed to study volumetric changesin DOX affected testes with co-administration of antioxidant Vitamin C. Design: An experimentalstudy. Setting: Institute of Basic Medical Sciences. Dow University of Health Sciences. Period:September 2011 to May 2012. Methods: Experimental study using thirty male mice of fiveweeks old were separated into 3 groups (A, B & C). Each group had ten mice and was treatedwith normal saline 1 ml intraperitoneal (IP) in group A, DOX alone (0.003 mg in 0.03ml /gmbody weight IP for 3 doses on 6th, 8th and 10th day of study) in group B and DOX (0.003 mgin 0.03ml /gm body weight IP for 3 doses on 6th, 8th and 10th day of study) + Vitamin C (0.5mg in 0.01ml/gm body weight per orumdaily) in group C. After completion of study, animalswere sacrificed and the testes were kept in Bouin’s fluid and volume was measured. Results:By using SPSSS version 16, statistical analysis was done, using ANOVA test to evaluate thesignificance of concerned parameter among different groups studied. The administration ofDOX induced significant reduction (P <0.001) of volume of testes when compared to controls.However co-administration of Vitamin C with DOX significantly increase (P <0.001) the volumeas compared to DOX group. Conclusion: This study suggested that the antioxidant VitaminC has a significant role in ameliorating the damage of testes induced by DOX, showingimprovement in the morphology and morphometry of testes.
