Wireless Power Transfer and Cooperative Jamming for Secrecy Throughput Maximization

This letter studies the secure communication between a wireless powered source node and a destination node in the presence of multiple eavesdroppers. We propose a hybrid base station (BS) scheme where the hybrid BS first transfers wireless power to the source and then performs cooperative jamming while the source transmits the information signal using the harvested energy. We maximize the secrecy throughput by jointly optimizing the time allocation, source transmit power, and redundancy rate under the secrecy constraint and transmit power constraint. We transform the secrecy throughput maximization problem into a convex optimization problem and obtain the optimal solutions efficiently. Numerical results illustrate that our solution is superior to other benchmark schemes.
Effects of tuning of ankle foot orthoses-footwear combination using wedges on stance phase knee hyperextension in children with cerebral palsy – Preliminary results

Purpose. This pilot study investigated the feasibility of reducing stance phase knee hyperextension in children with cerebral palsy by tuning the ankle foot orthoses-footwear combination (AFO-FC) using different sizes of wedges. Methods. Five children with cerebral palsy underwent three dimensional gait analysis and tuning of their AFO-FC using wedges. Data analysis was carried out by comparing relevant gait parameters between the non-tuned and tuned prescription. Results. Knee hyperextension during stance significantly decreased, and the shank to vertical angle was closer to normal after tuning. Although none of the other parameters showed statistically significant changes, the wide confidence intervals and lack of power indicated the likelihood of a type II error. Further, it was noted that the influence of tuning on temporal-spatial parameters was different between children with diplegia and those with hemiplegia. It was estimated that a sample size of 15 is required to detect significant changes at p = 0.05 and power of 0.8. Conclusions. The findings of this study clearly indicate the potential clinical utility of tuning using wedges to correct knee hyperextension during the stance phase in children with cerebral palsy. However, observations support the need for an adequately powered study to assess the long-term effects of tuning on gait parameters, activity level and quality of life.
A journey through the lectin pathway of complement—MBL and beyond

Mannose‐binding lectin (MBL), collectin‐10, collectin‐11, and the ficolins (ficolin‐1, ficolin‐2, and ficolin‐3) are soluble pattern recognition molecules in the lectin complement pathway. These proteins act as mediators of host defense and participate in maintenance of tissue homeostasis. They bind to conserved pathogen‐specific structures and altered self‐antigens and form complexes with the pentraxins to modulate innate immune functions. All molecules exhibit distinct expression in different tissue compartments, but all are found to a varying degree in the circulation. A common feature of these molecules is their ability to interact with a set of serine proteases named MASPs (MASP‐1, MASP‐2, and MASP‐3). MASP‐1 and ‐2 trigger the activation of the lectin pathway and MASP‐3 may be involved in the activation of the alternative pathway of complement. Furthermore, MASPs mediate processes related to coagulation, bradykinin release, and endothelial and platelet activation. Variant alleles affecting expression and structure of the proteins have been associated with a variety of infectious and non‐infectious diseases, most commonly as disease modifiers. Notably, the severe 3MC (Malpuech, Michels, Mingarelli, and Carnevale) embryonic development syndrome originates from rare mutations affecting either collectin‐11 or MASP‐3, indicating a broader functionality of the complement system than previously anticipated. This review summarizes the characteristics of the molecules in the lectin pathway.
HASTY, the Arabidopsis ortholog of exportin 5/MSN5, regulates phase change and morphogenesis

Loss-of-function mutations of HASTY (HST) affect many different processes in Arabidopsis development. In addition to reducing the size of both roots and lateral organs of the shoot, hst mutations affect the size of the shoot apical meristem, accelerate vegetative phase change, delay floral induction under short days, adaxialize leaves and carpels, disrupt the phyllotaxis of the inflorescence, and reduce fertility. Double mutant analysis suggests that HST acts in parallel to SQUINT in the regulation of phase change and in parallel to KANADI in the regulation of leaf polarity. Positional cloning demonstrated that HST is the Arabidopsis ortholog of the importin β-like nucleocytoplasmic transport receptors exportin 5 in mammals and MSN5 in yeast. Consistent with a potential role in nucleocytoplasmic transport, we found that HST interacts with RAN1 in a yeast two-hybrid assay and that a HST-GUS fusion protein is located at the periphery of the nucleus. HST is one of at least 17 members of the importin-β family in Arabidopsis and is the first member of this family shown to have an essential function in plants. The hst loss-of-function phenotype suggests that this protein regulates the nucleocytoplasmic transport of molecules involved in several different morphogenetic pathways, as well as molecules generally required for root and shoot growth.
Community Sentiment on Environmental Topics in Social Networks

We monitor social media, Twitter in particular, on a broad range of environmental issues such as climate change, green energy, sustainable development, climate policy targets. We analyze the social network of retweets about specific issues and we identify the influential users. We then characterize influential communities based on the prevalence of discussion topics in the tweet texts. As a novel and important aspect of our research, we also classify communities based on the prevalent sentiment with respect to the various discussion topics. We find differences among the major communities in their sentiment leanings towards various environmental issues.
Technical Aspects of the Parkes Error Grid

Background: The Parkes error grid, which was developed in 1994, presented performance zones for blood glucose (BG) monitors with borders that were not mathematically specified at the time the grid was published. Methods: In this article, we (1) review the history of the Parkes error grid, (2) present the never-before-published exact coordinates and specifications of the grid so that others may produce an exact replica of the original grid, and (3) discuss our suggestions how this metric should be applied. Results: The new ISO15197:2013 guideline for system accuracy assessment of BG meters for patient self-measurement incorporates use of this metric for defining acceptable accuracy of BG monitors. It is expected that, for regulatory purposes, this document will stipulate that the error grid version for type 1 diabetes should be applied with the caveat that only the A zone represents acceptable accuracy. Conclusions: It remains to be seen by how much the new error grid, which is currently being developed by the Food and Drug Administration/Diabetes Technology Society/American Diabetes Association/The Endocrine Society/Association for Advancement of Medical Instrumentation, will deviate from the Parkers error grid.
Prevalence of simple and abdominal obesity in Greek adolescents: the ADONUT study

The aim of this study was to assess the prevalence of underweight, normal body weight, overweight, obesity and abdominal obesity in Greek adolescents. A nationally representative sample of 37 344 Greek adolescents, aged 12–19 years old, was recruited from schools throughout the country during 2010–2012. Body weight, stature and waist circumference were measured. The prevalence of each weight status category was defined according to the International Obesity Task Force criteria and abdominal obesity was diagnosed according to the International Diabetes Federation. One‐third of the participants were either overweight or obese. Among adolescent boys, the prevalence of underweight was 3.3%, 27.9% were overweight and 8.9% were considered obese. Among the girls, 5.8% of the population were underweight, 19.4% were considered overweight and 6.0% obese. Abdominal obesity was diagnosed in 9.1% of the sample (8.9% of the boys and 9.2% of the girls). In 4.5% of the population, simple and central obesity coincided. The pooled prevalence of overweight and obesity as well as the rate of abdominal obesity appear to level off during the course of adolescence. The results indicate a high prevalence of overweight among Greek adolescents.
CD34+ cell subclasses and lymphocyte subsets in blood grafts collected after various mobilization methods in myeloma patients

BACKGROUND: Cyclophosphamide (CY) combined with granulocyte–colony‐stimulating factor (G‐CSF) is commonly used to mobilize stem cells in multiple myeloma (MM). Plerixafor may also be used with G‐CSF in patients who mobilize poorly or it may be added to chemomobilization to boost mobilization. Limited data are available on graft content collected after various mobilization methods.
Adaptable Service Level Objective Agreement (A-SLO-A) for Cloud Services

Reducing IT costs by using Cloud Computing is tempting for start up companies. To attract companies to outsource their services to Clouds, Cloud provider need to offer Service Level Objectives specified in SLAs individually for their customers. Cloud provider like Amazon can not afford to negotiate individual SLAs manually. Therefore, it becomes important to develop a format for machine-readable SLAs which can easily adapt to the individual Service Level Objectives requested by the customer any time. Because of its adaptability at run time by each individual customer on demand, this comply with the characteristics of Cloud Computing and to satisfies the customer’s requirements to be flexible. This paper describes an adaptable Service Level Objective Agreement (A-SLO-A) format being machine-processed to offer the possibility to integrate the SLA management into the highly automated processes of resource provisioning. Use cases show its applicability.
Iterative Message Passing for Pilot-Assisted Multiuser Detection in MC-CDMA Systems

Application of the belief propagation (BP) algorithm is proposed for pilot-assisted reception of multi-carrier code division multiple access systems where the input symbols are binary phase shift keying symbols. The proposed method utilizes a Bayesian network graph that includes channel parameters as explicit nodes representing random variables. Channel parameters in both frequency and time domains are included in the graph. The messages on the graph are obtained by making large system assumptions for the user symbols and Gaussian assumptions for the messages related to the channel parameters. Density evolution analysis is performed whose results match well with the simulation results. For the simulated scenario it is found that BP with the proposed graph outperforms channel estimation followed by graph based detection, and non-graph based iterative channel estimation.
Zen and Philosophy

Before engaged in writing his first book "An Inquiry into the Good" in 1991, the Japanese philosopher Kitaro Nishida had experienced decades of meditation. After the meditation, the problem that "Zen and philosophy" had appeared and continued throughout the fi rst period of Kitaro Nishida's philosophical thinking. Can we simply see Nishida philosophy as Zen; or whether it can be said that the exclusion of Zen had therefore made the Nishida philosophy; Or it can be said that Nishida philosophized Zen. This thesis will Analysis and discussion on such issues raised before.
Phenotypically continuous with clinical psychosis, discontinuous in need for care: evidence for an extended psychosis phenotype.

BACKGROUND Rates of self-reported psychotic experiences (SRPEs) in general population samples are high; however the reliability against interview-based assessments and the clinical significance of false-positive (FP) ratings remain unclear. DESIGN The second Netherlands Mental Health Survey and Incidence Study-2, a general population study. METHODS Trained lay interviewers administered a structured interview assessing psychopathology and psychosocial characteristics in 6646 participants. Participants with at least one SRPE (N = 1084) were reassessed by clinical telephone interview. RESULTS Thirty-six percent of participants with SRPEs were confirmed by clinical interview as true positive (TP). SPREs not confirmed by clinical interview (FP group) generated less help-seeking behavior and occurred less frequently compared with TP experiences (TP group). However, compared with controls without psychotic experiences, the FP group more often displayed mood disorder (relative risk [RR] 1.7, 1.4-2.2), substance use disorder (RR 2.0, 1.6-2.6), cannabis use (RR 1.5, 1.2-1.9), higher levels of neuroticism (RR 1.8, 1.5-2.2), affective dysregulation, and social dysfunction. The FP group also experienced more sexual (RR 2.0, 1.5-2.8) and psychological childhood trauma (RR 2.1, 1.7-2.6) as well as peer victimization (RR 1.5, 1.2-2.0) and recent life events (RR 2.0, 1.6-2.4) than controls without psychotic experiences. Differences between the FP group and the TP group across these domains were much smaller and less conclusive. DISCUSSION SRPEs not confirmed by clinical interview may represent the softest expression of an extended psychosis phenotype that is phenotypically continuous with clinical psychosis but discontinuous in need for care.
Improving wireless LAN performance in the presence of integrated multimedia services

A new multiplexing scheme for multimedia over wireless networks is proposed. The proposed scheme greatly accelerates data services in the presence of multimedia services compared to other schemes. Our scheme is also more energy-aware than other schedulers. The scheme provides soft QoS guarantee by enforcing cooperative coding in multimedia stations. The scheme results in lower rates of call rejection or dropping due to handover. It is suited for implementation at the base station in infrastructure basic service sets.
Sleep Apnea in Cluster Headache

The impetus to study sleep changes in a cluster population arose from a recent hypothesis that predicted the finding of sleep apnea in this disorder. It holds that cluster attacks may occur in response to oxygen desaturation. Proposed mechanisms involve impairment of carotid body activity secondary to hypothalamic-vasomotor regulatory dysfunction. Five chronic and five episodic cluster patients underwent nocturnal polysomnography, utilizing standard equipment for monitoring sleep status, cardiac activity, nasal and buccal air flow change, chest and abdominal breathing, muscle activity and oxygen saturation. All episodic patients and one of five chronic patients were found to have sleep apnea (60%). Mean apneas per hour during NREM sleep were similar to that of REM sleep; 26.7 and 28.2, respectively. Six patients with sleep apnea experienced 14 cluster headache attacks during the study period. Eight attacks (57%) followed episodes of oxygen desaturation ranging from 65% to 85%. In the sleep apnea group, 8 out of 14 attacks (57%) were associated with REM; three without, and five following oxygen desaturation. Of the non-apnea group, all of whom had chronic cluster headache, none of 5 attacks were associated with oxygen desaturation, and only 2/5 attacks occurred in relation to REM. Thus, our study showed that sleep apnea was a common finding in a randomly selected group of episodic cluster patients; and most nocturnal attacks were preceded by oxyhemoglobin desaturation and REM-related. These findings were uncommon in the chronic cluster group.
Prospective comparative study of culture specimens and methods in diagnosing influenza in adults

Influenza is diagnosed by culturing influenza virus in respiratory secretions.1 Although childhood infection with respiratory syncytial virus is detected by culturing nasopharyngeal aspirates, in adults with influenza throat swabs are generally taken. This report compares culture of nasopharyngeal aspirates with culture of throat swabs and rapid culture methods with standard methods in detecting influenza virus. Between November 1995 and January 1996, 41 patients were admitted to the Infectious Disease Unit at the Royal Hallamshire Hospital, Sheffield, with symptoms and signs consistent with influenza. Thirty nine of these patients gave their informed consent to undergo nasopharyngeal aspiration in addition to routine investigations. The procedure was performed with a small suction catheter and trap. Viral transport medium was added to the aspirate and samples were sent to the laboratory within 24 hours. Nasopharyngeal aspirates and throat swabs were cultured …
Diagnosis and management of headaches in young people and adults: summary of NICE guidance

Headaches are a common problem that many clinicians in primary and secondary care find difficult to treat.1 2 Once the serious causes of headache have been excluded (such as infection, tumour, bleeding, and arteritis), the major health and social burden of headaches can be attributed to primary headache disorders (cluster headache, migraine, and tension-type headache) and headache caused by the overuse of medications. Straightforward advice is needed for anyone working in the NHS on the diagnosis and treatment of these common disorders and the prevention of medication overuse headache. This article summarises the most recent recommendations from the National Institute for Health and Clinical Excellence (NICE) on the diagnosis and management of headaches in young people and adults.3 NICE recommendations are based on systematic reviews of the best available evidence and explicit consideration of cost effectiveness. When minimal evidence is available, recommendations are based on the Guideline Development Group’s experience and opinion of what constitutes good practice. Evidence levels for the recommendations are given in italic in square brackets. ### Assessment: indications for considering additional investigation [ All based on the experience and opinion of the Guideline Development Group (GDG )]
Fast Image Segmentation with Lv Distance between Local Cumulative Histograms

This paper presents two new region-based active contour models in a variation framework for image segmentation. In these models, to quantify the similarity measurement between two regions, we propose to compare their respective cumulative histograms with the L1,L2,L∞ distances which are often applied in image comparison. For example, to compute the similarity, the KolmogorovSmirnov test by using the L∞ distance is the most popular one. Our first energy model is based on minimizing Lv distance between two cumulative histograms of different regions, together with a geometric regulation term that penalizes the length of region boundaries. The second model is the localization of the first model with the popular local method. To solve these models, we describe a fast minimization algorithm with the Split-Bregman method, which can find the global minimizer. Finally, to illustrate the robust and accurate segmentations with the proposed models, we show some experimental results on some images.
Authentication of Identical Twins Using Tri Modal Matching

With the increase in the number of twin births in recent decades, there is a need to develop alternate approaches that can secure the biometric system. In this paper, a new approach for identifying identical twins on the basis of a multimodal identification system that uses three different features namely face, finger print and lip print to identify people. A newly developed multimodal biometric system possesses a number of unique qualities, starting from utilizing Kernel Similarity with Euclidean distance methods for face matching, Possibilistic Fuzzy C-means clustering (PFCM) for fingerprint matching and Fixed K-means Clustering features for lip print matching and fused the information for effective recognition and authentication. The importance of considering these boundary conditions, such as twins, where the possibility of errors is maximum will lead us to design a more reliable and robust security system. The proposed approach is tested on a real database consisting of 429 pair of identical twin images and shows promising results. The Receiver Operating Characteristics also shows that the proposed method is superior compared to other techniques, subsequently, the experimental results prove the ability of proposed method to recognize a pair of identical twins at ease.
Detection of breast tumor antigen-sensitive circulating T-lymphocytes by antigen-stimulated active rosette formation.

Abstract Preoperative circulating human breast tumor-associated antigen (BTA)-sensitive T-lymphocytes were detected in breast carcinoma patients by the antigen-stimulated active rosette-forming T-cell (AgARFC) assay. Incubation of peripheral lymphocytes isolated from tumor-bearing patients with either of two soluble allogeneic BTA extracts (BTA 1 and BTA 2 ) produced higher percentages of AgARFC than did incubation in antigen-free media (ARFC). The circulating BTA-sensitive T-cell subpopulation, as %AgARFC — %ARFC, of 56 patients found to have invasive breast cancer was 6.4 ± 0.9% (S.E.) for BTA 1 and 7.4 ± 0.7% for BTA 2 . These values were significantly higher than the mean responses to corresponding isologous lymphocyte histocompatibility antigen (HA) extracts (HA 1 and HA 2 ), 1.1 ± 0.5% for HA 1 and 2.2 ± 0.8% for HA 2 ( p p p p
Evidence for the thermal Sunyaev-Zel'dovich effect associated with quasar feedback

Using a radio-quiet subsample of the Sloan Digital Sky Survey spectroscopic quasar catalogue, spanning redshifts 0.5-3.5, we derive the mean millimetre and far-infrared quasar spectral energy distributions (SEDs) via a stacking analysis of Atacama Cosmology Telescope and Herschel-Spectral and Photometric Imaging REceiver data. We constrain the form of the far-infrared emission and find 3 sigma-4 sigma evidence for the thermal Sunyaev-Zel'dovich (SZ) effect, characteristic of a hot ionized gas component with thermal energy (6.2 plus or minus 1.7) 10 (exp 60) erg. This amount of thermal energy is greater than expected assuming only hot gas in virial equilibrium with the dark matter haloes of (1-5) 10(exp 12) h(exp 1) solar mass that these systems are expected to occupy, though the highest quasar mass estimates found in the literature could explain a large fraction of this energy. Our measurements are consistent with quasars depositing up to (14.5 +/- 3.3)tau (sub 8)(exp -1) per cent of their radiative energy into their circumgalactic environment if their typical period of quasar activity is tau(sub 8) x 108 yr. For high quasar host masses, approximately 10(exp 13) h(exp 1) solar mass, this percentage will be reduced. Furthermore, the uncertainty on this percentage is only statistical and additional systematic uncertainties enter at the 40 per cent level. The SEDs are dust dominated in all bands and we consider various models for dust emission. While sufficiently complex dust models can obviate the SZ effect, the SZ interpretation remains favoured at the 3 sigma-4 sigma level for most models.
