Controlling user Access to Cloud-ConnectedMobile Applications by the Means of Biometrics

— Cloud-associated portable applications are turning into a prominent answer for omnipresent access to online administrations, for example, cloud information stockpiling stages. The appropriation of such applications has security and protection suggestions that are making people reluctant to relocate delicate information to the cloud; accordingly, new secure confirmation conventions are required. In this article, we propose a constant verification approach coordinating physical (face) and social (contact and hand developments) biometrics to control client access to cloud-based portable administrations, going past one-time login .
PREVALENCE OF SURGICAL SITE INFECTION AND ASSOCIATED FACTORS AMONG MOTHERS AFTER CESAREAN DELIVERY IN ZEWDITU MEMORIAL HOSPITAL

ABSTRACTBACKGROUND: Cesarean delivery is the most common major operation carried out in obstetrics; constituting about 15% of all deliveries worldwide. Surgical site infections (SSIs) are among the most common infectious complications after cesarean delivery; which increase maternal morbidity and mortality, hospital stay and the cost of treatment. Hence, the aim of this study was to determine the prevalence of SSIs and associated factors among mothers after cesarean delivery.METHODS: Institution based cross-sectional study was conducted in Zewditu Memorial Hospital from December, 2017 to April, 2018. A semi-structure questionnaire was used to collect data. Wound site was examined on the 3rd postoperative day and 1st postnatal visit. On the 14th and 30th postoperative day, each participant was contacted through telephone for any signs of wound infection. Bivariate and multivariate logistic regression analysis were done to identify the association between predictors and SSIs. A level of P 12 hours), prolonged labor (>12 hours) and anemia were significant predictors of SSIs.KEYWORDS: Cesarean section, Postpartum, Surgical site infection(Ethiopian Journal of Reproductive Health; 2018; 10; 4: 21-32)
The impact of general perceived self-efficacy on regret

The purpose of this study was to shed light on the relationship between perceived self-efficacy and regret. I measured regret by its two subcomponents, cognitive regret and affective regret . I hypothesized first that as perceived self-efficacy increases, so too would the experience of cognitive regret. Second, I predicted that as perceived self-efficacy decreases, the experience of affective regret would increase. I expected that people with more perceived self-efficacy, believing themselves more capable globally, would be more likely to reflect on and learn from their mistakes. In contrast, I thought people with less perceived self-efficacy would tend to focus on the emotional distress that accompanies regret, feeling less able to have modified their past decisions. However, my hypotheses were not supported by the data. Although my predictions were not supported, the goal of promoting the most functional regret experience possible remains. Future research could establish a causal relationship between perceived self-efficacy, both general and specific, and regret.
Transparency in Public-Private Partnerships: Some Lessons from Scandinavia and Australia

This paper examines the transparency of public-private partnerships (PPPs). The key question is “How has transparency and accountability been implemented in PPPs? ”. PPPs in infrastructure have been presented as enabling synergy and as a major alternative to previous contracting out techniques. These partnerships have most usually involved the preferential use of private finance, highly complex ‘bundled’ infrastructure delivery contract arrangements and new governance and accountability assumptions. Risk management is also particularly important to PPPs. Contracts between the governments and partnering private firms, however, have also been more complex and have not necessarily lead to simple synergy, but to more negotiations and governance structures. One ongoing concern from critics has been the accusation of illegitimacy due to the use by governments of these contracts to hold project information secret, rather than providing details of the deals to citizens. This paper first presents the transparency concept as it relates to modern day infrastructure PPPs. Second, the paper discusses how transparency and PPPs are related, and suggests a typology of transparency based on degree on openness and phases of the PPP process. Third, the paper examines empirical evidence on transparency elements in PPP contracts and governance structures based on two cases from Scandinavia and Australia. Fourth, the paper concludes by observing how different transparency dimensions relate to the different phases in a PPP project, including the important point about the contract institution that defines a PPP. The paper also concludes by suggesting some ways forward to improve transparency in future PPPs to enhance legitimacy.
Direct Ray Tracing of Phong Tessellation

There are two major ways of calculating ray and parametric surface intersections in rendering. The first is through the use of tessellated triangles, and the second is to use parametric surfaces together with numerical methods such as Newton's method. Both methods are computationally expensive and complicated to implement. In this paper, we focus on Phong Tessellation and introduce a simple direct ray tracing method for Phong Tessellation. Our method enables rendering smooth surfaces in a computationally inexpensive yet robust way.
EULAR recommendations for the management of rheumatoid arthritis with synthetic and biological disease-modifying antirheumatic drugs: 2016 update

Recent insights in rheumatoid arthritis (RA) necessitated updating the European League Against Rheumatism (EULAR) RA management recommendations. A large international Task Force based decisions on evidence from 3 systematic literature reviews, developing 4 overarching principles and 12 recommendations (vs 3 and 14, respectively, in 2013). The recommendations address conventional synthetic (cs) disease-modifying antirheumatic drugs (DMARDs) (methotrexate (MTX), leflunomide, sulfasalazine); glucocorticoids (GC); biological (b) DMARDs (tumour necrosis factor (TNF)-inhibitors (adalimumab, certolizumab pegol, etanercept, golimumab, infliximab), abatacept, rituximab, tocilizumab, clazakizumab, sarilumab and sirukumab and biosimilar (bs) DMARDs) and targeted synthetic (ts) DMARDs (Janus kinase (Jak) inhibitors tofacitinib, baricitinib). Monotherapy, combination therapy, treatment strategies (treat-to-target) and the targets of sustained clinical remission (as defined by the American College of Rheumatology-(ACR)-EULAR Boolean or index criteria) or low disease activity are discussed. Cost aspects were taken into consideration. As first strategy, the Task Force recommends MTX (rapid escalation to 25 mg/week) plus short-term GC, aiming at >50% improvement within 3 and target attainment within 6 months. If this fails stratification is recommended. Without unfavourable prognostic markers, switching to—or adding—another csDMARDs (plus short-term GC) is suggested. In the presence of unfavourable prognostic markers (autoantibodies, high disease activity, early erosions, failure of 2 csDMARDs), any bDMARD (current practice) or Jak-inhibitor should be added to the csDMARD. If this fails, any other bDMARD or tsDMARD is recommended. If a patient is in sustained remission, bDMARDs can be tapered. For each recommendation, levels of evidence and Task Force agreement are provided, both mostly very high. These recommendations intend informing rheumatologists, patients, national rheumatology societies, hospital officials, social security agencies and regulators about EULAR's most recent consensus on the management of RA, aimed at attaining best outcomes with current therapies.
Spoligotyping analysis of Mycobacterium tuberculosis in Khyber Pakhtunkhwa area, Pakistan

Background: Spoligotyping is a reproducible, reverse hybridization approach for genotyping of Mycobacterium tuberculosis complex (MTBC). Molecular typing of MTBC is helpful for understanding and controlling tuberculosis epidemics. Methods: Spoligotyping was performed on 166 clinical isolates of Mycobacterium tuberculosis (MTB) collected from 25 districts of Khyber Pakhtunkhwa, Pakistan. Results were compared to SITVIT2, an online database developed by the Institut Pasteur de la Guadeloupe, France. Results: Spoligotyping results showed that 145 strains (88%) displayed known patterns while 21 (12%) were new. Lineage 3/Central Asian strain (L3/CAS) was the predominant family (73%, χ2=19.9, P=0.001), followed by L2/Beijing (5.4%) and L4 (4.2%). L3/CAS1-Delhi was the major sublineage (82%) among the L3/CAS family (χ2=664, P=0.0001). Analysis showed that the majority of the clinical isolates with an unknown pattern had an evolutionary link with the L3/CAS strain, and nine (5.4%) of the unknown strains were epidemiologically linked and were tentatively named L3/CAS-KP (Khyber Pakhtunkhwa). Conclusion: The present study demonstrated that L3/CAS is the predominant lineage of MTB, widely distributed in different areas of the Khyber Pakhtunkhwa province of Pakistan. Spoligotyping patterns of some clinical isolates could not be matched to other reported patterns in an international database. Other tools, such as mycobacterial interspersed repetitive unit–variable number tandem repeat (MIRU-VNTR), will be helpful in future investigations into the epidemiological characteristics of clinical isolates in the Khyber Pakhtunkhwa province.
AN H-SHAPED DIFFERENTIAL FED PATCH ANTENNA FOR A GAN BASE STATION TRANSMITTER

In this paper, a differentially fed, structurally simple, patch antenna, operating at 5.2 GHz is presented. The proposed antenna is particularly designed for a base station, Gallium Nitride (GaN) transmitter. The antenna is composed of an H-shaped patch, backed by a ground plane, with two differential feeds placed at the longitudinal edges. The size of the antenna is 0. 55λ0 × 0. 49λ0 × 0. 27λ0 (where λ0 is the free space wavelength at the center frequency). A prototype of the stand-alone antenna is designed, fabricated, and measured. The antenna offers a voltage standing wave ratio (VSWR) bandwidth of 4% and a differential impedance of 100Ω, which matches most of the differential integrated circuits. The measured gain and directivity of the proposed differential antenna are 5.3 dBi and 7 dB, respectively. From simulation it is observed that the proposed antenna possesses a front to back ratio of 15.69 dB and a 3dB beamwidth of 84◦. The measured peak efficiencies of the antenna in the lower and higher bands are 84% and 59%, respectively. Details of the design and lumped model, along with the experimental and simulated results, are presented and discussed. The effect of scaling different design parameters for operation at different frequency bands is considered as well.
A neurodynamical retinal network based on reaction-diffusion systems

A dynamical model for retinal processing is presented. The model describes the output of retinal ganglion cells whose receptive field is composed of a center and a surround combining linearly. However, in comparison to the classical difference-of-Gaussian (DOG) model, center and surround are generated in two separate layers of reaction-diffusion systems, through a difference in the speed of activity-propagation between both layers. Thus, intra-layer coupling is based exclusively on next-neighbor interactions. This makes the model suitable for VLSI implementation. Furthermore, the layers are connected by equations with feedback-inhibition to form ON-center/OFF-surround and OFF-center/OFF-surround receptive fields. The model's output in the early dynamics corresponds to high-resolution contrast information, whereas the output at later times can be considered as correlated with local brightness and darkness, respectively. To examine this in more detail, simulations with the Hermann/Hering-grid and grating induction were carried out.
Quantitative Study on the Mechanism of Synergy between Agricultural Institutions of Higher Learning and Agricultural Enterprises

The purpose of the study is to explore the mechanism and effect of the equivalent synergies on the collaborative cooperation between university and enterprise. The characteristics of collaboration include three dimensions: organizational synergy, strategic synergy, and knowledge synergy. Each dimension is determined by the internal and external factors of the partners. Therefore, whether the partners can provide equal resources in different dimensions will impact the intensity of cooperative willingness. Taking the students of agricultural colleges and universities as the research object, this paper analyses the necessity of students' participation in teaching management in agricultural colleges and universities from the perspective of cultivating students' self-development, adapting to the transformation of management concept and perfecting modern university system. Students' participation in teaching management in agricultural colleges and universities is guaranteed by concepts, subjects and laws. In order to verify the effect of equivalence and the hypotheses proposed, the study obtained and analyzed data via the questionnaire. The results show that equivalence has a positive influence on the cooperative willingness and synergy, then the willingness can also indirectly affect the collaborative performance. This study provides a new path to improve the collaborative performance for university-enterprise collaborative cooperation.
EFFECT OF HOME PHYSIOTHERAPY ON BALANCE AND DYNAMIC AS WELL AS KINEMATIC MOVEMENT CHARACTERISTICS OF THE DOMINANT HAND FOR PEOPLE WITH PARKINSON’S DISEASE

Research background and hypothesis. Parkinson’s disease (PD) is a disease of the elderly, characterized by motor symptoms (resting tremor, bradykinesia, rigidity, and postural instability) when the extrapyramidal system lacks dopamine. Studies have shown that physiotherapy together with the usual medication used to treat PD can slow down the increasing immobility. Research aim was to assess the effect of home physiotherapy on balance and dynamic as well as kinematic movement characteristics of the dominant hand for people with Parkinson’s disease. Research methods. Research group consisted of 8 patients with PD, stage 1–2 of the disease, the symptoms of which were expressed on the right hand. The study was conducted using Fullerton balance test and the human arm and leg movement Dynamic Parameter Analyser DPA-1. Research results. Balance as well as kinematic and dynamic characteristics of movements for patients with PD statistically significantly improved (p < 0.05) after the physiotherapy exercise cycle at home. Discussion and conclusions. After physiotherapy, coordination of the dominant hand for patients with PD significantly improved: reaction time became shorter, maximum and average task speed increased, balance improved statistically significantly. The results showed that physiotherapy at home was an effective and reliable way for patients with PD to train their balance as well as kinematic and dynamic characteristics of their movements.
Achieving a High Fill Factor and Stability in Perylene Diimide–Based Polymer Solar Cells Using the Molecular Lock Effect between 4,4′‐Bipyridine and a Tri(8‐hydroxyquinoline)aluminum(III) Core

Two novel perylene diimide (PDI)–based derivatives, Alq3‐PDI and Alq3‐PDI2, are synthesized by flanking a 3D tri(8‐hydroxyquinoline)aluminum(III) (Alq3) core with PDI and a helical PDI dimer (PDI2) to construct high‐performance small molecular nonfullerene acceptors (SMAs). The 3D Alq3 core significantly suppresses the molecular aggregation of the resulting SMAs, leading to a well‐mixed blend with a PTTEA donor polymer and weak phase separation. Compared with Alq3‐PDI, the extended π‐conjugation of Alq3‐PDI2 results in higher‐order molecular packing, which improves the absorption and phase separation behavior. Thus, the Alq3‐PDI2 devices have higher Jsc and FF values and better device performance, which are further enhanced by a small amount of 4,4′‐bipyridine (Bipy) as an additive. The coordination between Bipy and the Alq3 core promotes molecular packing and phase separation, which lower charge recombination and enhanced charge collection in the resulting devices. Therefore, a largely improved Jsc of 15.74 mA cm−2 and very high FF of 71.27% are obtained in the Alq3‐PDI2 devices, resulting in a power conversion efficiency of 9.54%, which is the best value reported for PDI‐based polymer solar cells. The coordination can also serve as a “molecular lock,” which prevents molecular motion and thus improves device stability.
A cellular atlas of the developing meninges reveals meningeal fibroblast diversity and function

The meninges, a multilayered structure that encases the CNS, is composed mostly of fibroblasts, along with vascular and immune cells. Meningeal fibroblasts are a vital source of signals that control neuronal migration and neurogenesis yet strikingly little is known about their development. We used single cell RNA sequencing to generate a cellular atlas of embryonic meningeal fibroblasts in control and Foxc1-KO mice in which severe CNS defects arise from failed meningeal fibroblast development. We report unique transcriptional signatures for dura, arachnoid and pial fibroblasts and identify S100a6 as the first unique marker of the pial layer. We describe a new meningeal fibroblast subtype marked by µ-Crystallin expression and show these cell types and markers are conserved in human fetal meninges. Our analysis demonstrates layer specific production of extracellular matrix components, transporter expression, and synthesis of secreted factors. Lastly, the cellular atlas of Foxc1-KO meninges provides insight into their severe phenotype, confirming a massive loss in arachnoid and dura fibroblasts and Foxc1-KO pial fibroblasts are so altered that they cluster as a different cell type based on gene expression. These studies provide an unprecedented view of meningeal fibroblast development, highlighting unexpected fibroblast diversity and function, while providing mechanistic insights into the meninges role in CNS development.
Marangoni Effect in Second Grade Forced Convective Flow of Water Based Nanofluid

Advances in nanotechnology especially in nanofluids comprising of a typical base fluid saturated with nano-size metallic particles with enhanced thermophysical properties is one of the hot topics in industrial as well as engineering applications of applied mathematics. This article explores the impact of Lorentz forces and Maragoni effect on second grade nanofluid forced convective flow. A two phase model is chosen to validate the nanofluid. Series solutions are achieved through HAM after transformation of PDEs into ODEs. The Brownian motion effect, Thermophoresis and the Marangoni effect are the main influencing factors for present flow model. In addition, the influence of pertinent fluid parameters such as Schmidt number, Magnetic number and Prandtl number on the velocity, temperature and concentration profiles is discussed with the help of graphs. With an enhanced Marangoni factor the hydraulic boundary layer thickness shows enhancement.

ConferenceSense: monitoring of public events using phone sensors

We explore the use of a participatory sensing paradigm, where data generated from individual smartphones is used to extract and understand collective properties of temporary public gatherings and events (e.g., concerts & conferences). We focus on the use of this paradigm at a technical conference, and describe the design, implementation and deployment of ConferenceSense, an application that uses multiple sensor and human-generated inputs from attendees' smartphones to infer context, such as the start time of a session or the degree of interaction during a tea break. Based on data collected from multiple attendees at a 3-day conference, we explore how ConferenceSense can be used for monitoring and collecting event statistics, and describe challenges and open questions.
Crocodile management in Timor-Leste: Drawing upon traditional ecological knowledge and cultural beliefs

ABSTRACT Cultural beliefs based on Timor-Leste´s creation myth “Lafaek Diak – The Good Crocodile” are anchored in the East Timorese traditional belief system lulik and involve worship of the widely distributed, but dangerous, saltwater crocodile (Crocodylus porosus). The wild saltwater crocodile population and rate of fatal attacks on people are both increasing due to conservation action. More innovative management is needed to reduce the frequency of attacks, but reverence for crocodiles constrains the management options available. We used semi-structured interviews with Timorese stakeholders (25 local authorities, 10 national experts, 15 citizens) to understand the cultural beliefs and traditional ecological knowledge underlying human-crocodile interactions, and conflict (HCC) in Timor-Leste. Interviewees knew this species was a risk (respect, fear) and its population was expanding, and had culturally determined beliefs (ceremonies, rituals) that included differentiating between local “ancestor” crocodiles and invasive “troublemakers. ” Cost-effective management could integrate stakeholder groups, especially traditional elders and local knowledge holders.
The intra-individual relationship between self-reported valence and heart rate in a daily life setting

Objectives. There is growing interest in how feelings are related to health. Scientists claim that feelings are related to heart rate (HR) and can therefore be an influencing factor on health. Studies show that the more pleasant or unpleasant feelings are, the higher is HR. Therefore, HR is assumed to be related to feelings. Nevertheless, only a limited number of studies investigated that psychophysiological relationship intra-individually, meaning instead of drawing conclusion from the group mean data using intra-individual correlations. Therefore, the present study investigates the intra-individual relationship between HR and self-reported valence and its consistency. Methods. In total 35 participants with an age ranging from 19 to 70 and either Dutch or German nationality participated within this study. The participants were asked to wear a biosensor measuring HR for seven days. Self-reported valence was measured with the aid of a smartphone application. For each individual intra-individual correlations were calculated. These correlations were split in two halves, the first time randomly and the second time into two time-based halves. This enables to make judgments about the consistency of the correlations. Findings. The correlations vary in strength and consistency. Nevertheless, those are neither consistent nor significant. There is no indication for a positive or negative relationship because there are as many positive as negative correlations. The differences among the correlations of the time-based split are higher, indicating a change during study period. Contradicting previous findings, it is concluded that HR is not related to self-reported valence. Discussion. Future studies should investigate a possible change in awareness of feelings as a possibly influencing factor to valence. The data of HR should be considered carefully as there is no correction of the effect of movement executed. Next to that, it is recommended to use eventbased sampling enabling gathering specific and accurate data of HR and self-reported valence.
