Secure and Capable of Data Communication Procedure for Wireless Area Network

Wireless Body Area Networks (WBANs) are expected to play a major role in the field of patient-health monitoring in the near future, which gains tremendous attention amongst researchers in recent years. One of the challenges is to establish a secure communication architecture between sensors and users, whilst addressing the prevalent security and privacy concerns. In this paper,we propose a communication architecture for BANs, and design a scheme to secure the data communications between implanted/wearable sensors and the data sink/data consumers (doctors or nurse) by employing Ciphertext-Policy Attribute Based Encryption(CP ABE) and signature to store the data in ciphertext format at the data sink, hence ensuring data security. Our scheme achieves role-based access control by employing an access control tree defined by the attributes of the data. We also design two protocols to securely retrieve the sensitive data from a BAN and instruct the sensors in a BAN. We analyze the proposed scheme, and argue that it provides message authenticity and collusion resistance, and is efficient and feasible. We also evaluate its performance in terms of energy consumption and communication/computation overhead.
Experience with designing a requirements and architecture management tool

Effective tool support is much needed for the tedious and error prone task of managing system requirements and system architectures. With the primary objective of providing practical support for software engineers, we have developed a tool for managing system requirements, system architectures and their traceability which is being used in real-world industrial projects. The tool is based on a well considered information model of system requirements and architecture, and embodies a set of document templates providing guidance for software engineers. The author reports on experience in designing and improving the tool. In particular, we highlight a number of case studies that played a significant role formulating the information model and document templates, and provide an assessment of the tool relative to existing practice.
Radiation and host retinoic acid signaling promote the induction of gut‐homing donor T cells after allogeneic hematopoietic stem cell transplantation

Intestinal graft‐versus‐host disease (GVHD) remains a devastating complication after allogeneic hematopoietic stem cell transplantation (HSCT). Although it has been well established that gut‐tropic donor T cells expressing integrin α4β7 are required to cause intestinal damage, the factors that control the induction of this pathogenic T cell population remain to be identified. Retinoic acid (RA) plays an important role in inducing α4β7 expression on T cells. In this study, we showed that gene expression of retinaldehyde dehydrogenase, the key enzyme involved in RA biosynthesis, is significantly increased in the spleen and mesenteric lymph nodes (MLNs) of irradiated mice. In a C57BL/6‐into‐B6D2F1 allogeneic HSCT model, irradiation significantly increased the induction of α4β7+‐donor T cells in mesenteric lymph nodes and spleen. Furthermore, we found that the RA pathway modulates the ability of dendritic cells to imprint gut‐homing specificity on alloreactive T cells. We also showed that host dendritic cell RA signaling influences GVHD risk. Our studies identified radiation and recipient RA signaling as 2 primary factors that dictate the magnitude of gut‐homing donor T cell induction after allogeneic HSCT. Attenuating radiation‐associated inflammation and modulating host RA signaling represent feasible strategies to mitigate intestinal GVHD by reducing gut‐seeking pathogenic donor T cells.
Synthesis of a material for semiconductor applications: Boron oxynitride prepared by low frequency rf plasma-assisted metalorganic chemical vapor deposition

We have synthesized a material, boron oxynitride (BON), deposited as films on Si(100) substrates by low frequency rf-derived plasma-assisted metalorganic chemical vapor deposition (MOCVD), and have studied the electrical and optical properties of these films. The effects of growth conditions such as the flux of the feed gas and growth time on these properties are investigated. Our data show that the electrical resistance decreases with an increase in nitrogen flux and growth time. Amorphous BON thin films grown at relatively low temperatures have higher resistance than microcrystal-containing films deposited at high temperature. Thus by controlling the nitrogen content of the film we can make BON thin films that are either semiconducting or insulating. We also monitored optical emission spectra (OES) during MOMCVD to analyze reaction of the gas phase in the plasma. Based on the OES result we confirm that BON thin films can be prepared under a nitrogen plasma.
Deposition of nanoscale multilayer CrN/NbN physical vapor deposition coatings by high power impulse magnetron sputtering

Nanoscale multilayer CrN/NbN physical vapor deposition (PVD) coatings are gaining reputation for their high corrosion and wear resistance. However, the CrN/NbN films deposited by ABS™ (arc bond sputtering) technology have some limitations such as macrodroplets, porosity, and less dense structures. The novel HIPIMS (high power impulse magnetron sputtering) technique produces macroparticle-free, highly ionized metal plasma, which brings advantages in both surface pretreatment and coating deposition stages of the PVD process. In this study, nanoscale multilayer CrN/NbN PVD coatings were pretreated and deposited with HIPIMS technology and compared with those deposited by HIPIMS-UBM (unbalanced magnetron) and by the ABS™ technique. In all cases Cr+ etching was utilized to enhance adhesion by low energy ion implantation. The coatings were deposited at 400 °C with substrate biased (Ub) at −75 V. During coating deposition, HIPIMS produced significantly high activation of nitrogen compared to the UBM as observed w.
Protein/Creatinine Ratio In Random Urine Specimens For Quantitation Of Proteinuria In Pre-Eclampsia

Objective: The purpose of this study is to determine if a patient's protein values using the protein /creatinine ratio correlates with the 24hour value to confirm the diagnosis of preeclampsia. Study Design: The study population included 86 patients with hypertensive disorders of pregnancy. Patients' urine was collected over 24 hours. The urine volume, and total protein in the 24-hour samples was evaluated. Urine distick test and the Protein /creatinine ratio in a spot urine sample were compared to the 24-hour results. The test of validity and reliability was done using the sensitivity, specificity, false positive and the false negative rate. Also assessed were the positive and negative predictive value and the accuracy. Results: Eighty-six pregnant patients completed the study. There was a strong correlation between the random urinary proteinto-creatinine ratio and the quantitation of 24-hour proteinuria. Conclusion: The presented data support a strong correlation between random urinary protein-to-creatinine ratio and quantitation of 24-hour proteinuria in hospitalized pregnant patients with preeclampsia.
Lucio Fontana: The Artist's Materials

This is the first English language technical study of one of the most important Italian artists of the post-WWII period. Lucio Fontana (1899-1968) is widely regarded as one of the most influential and innovative post-World War II Italian artists. Best known for his tagli - slashed, mostly monochromatic canvases - Fontana fashioned a remarkably multifaceted oeuvre that encompasses architecture, sculpture, and ceramics, as well as painting. In his quest to expand the vocabulary of his art, Fontana subjected the pictorial surface of his paintings to a remarkable assortment of punctures, gashes, and slashes, as well as adornments of glass fragments, glittering aluminium flakes, and sand. This richly illustrated book presents the first technical study in English of this important painter. Initial chapters present an informative overview of Fontana's life and work.
Distributed Event Correlation and Self-Managed Systems

The systems that currently provide Internet users with sophisticated e-business services struggle to offer high availability guarantees while being managed as regular systems, because management architectures rely on the manager-agent paradigm and domain-based distribution. In this paper, we argue that e-business information systems should instead be structured as self-managed systems: they need to detect problems by themselves, work out the cause of each problem, and take corrective actions independently of any external entity. They should not depend on external managers for their efficiency and robustness. To achieve this, we propose an organizational model that allows management architectures to take into account the specific requirements of self-managed systems, and investigate how to distribute event correlation in the presence of self-managed systems.

Air-tightness Evaluation of Tube Structures for Super-speed Tube Railway Systems: I. Analytical Modeling and Material Test

This paper presents a preliminary study for air-tightness evaluation of vacuum tube structures for super-speed tube railway systems. The formula for flow rate of the air caused by the pressure difference of the inside and outside of the tube structure is derived based on Darcy`s law. A test is then performed to measure the air-permeability of concrete with various compressive strengths, the result of which is used for analytical simulation of the air intrusion for a tube structure with a preliminarily defined section. It has been shown that concrete with the compressive strength of at least more than 50MPa is recommended for effective operation and maintenance of the vacuum pump systems, as the air-permeability of concrete is inversely proportional to the exponent of its compressive strength.
Evaluation of Knowledge, Attitudes, and Practices about Exclusive Breastfeeding among Women in Italy

Background: The aim of this study was to assess the level of knowledge, attitudes and behaviors of women about breastfeeding in Italy. Methods: A cross-sectional survey was carried out between January and June 2016 in the Campania Region among mothers who were going to six public vaccination centers. Data were collected by two researchers through face to face interviews. Results: Two thirds of the women had heard on exclusive breastfeeding (64.6%) and the 71% of them knew that exclusive breastfeeding should be practiced for at least six months. Nearly all mothers had breastfed their child (93.2%), but only 33.3% of them had practiced exclusive breastfeeding for at least six months. Women who agree that breastfeeding creates a positive relationship between the mother and the child, who practiced exclusive breastfeeding during the hospital stay, and who had received breastfeeding advice at hospital discharge were more likely to practice exclusive breastfeeding for at least six months. Conclusions: The results of this survey may be helpful to policy makers and managers when planning educational interventions on breastfeeding both during pregnancy and during hospital admissions for delivery. Indeed, there is a need to increase efforts to make mothers aware of health benefits of breastfeeding for themselves and their offspring during their hospital stay after delivery. This research has the potential to increase exclusive breastfeeding rates and subsequent maternal and child health outcomes.
Investigating the Current Status and Role of Quality Managers in Greece

Introduction In recent years quality is becoming the most common used word in the world business environment. Quality is the major concern and a strategic goal in the overall corporate strategy covering all functions within the organization. Research shows that quality is positively related to increased productivity, production efficiency and lower overall costs, market share optimization, etc. According to all quality experts’ quality is everybody’s job and the overall responsibility lies on the top-level management. However, the extensive adaptation and implementation of the ISO 9000 and the increasing customer-orientation focus of organizations brought quality managers at the scene. Quality Managers are usually the people responsible for the implementation and optimization of organization’s quality system and are the link between the company and the certification body. The aim of this paper is to investigate the current status and the role of the Quality Managers in selected ISO 9000:2000 certified Greek Industrial organizations. The purpose is to examine their professional skills and knowledge, their roles and responsibilities, their future and their fit within the organization. In recent years quality managers were faced with a series of new challenges stemming from the prerequisites of the ISO 9000 certification. The transition from quality control to quality assurance and then to total quality management gave the quality managers new responsibilities and new set of roles demanding more and better skills and knowledge. However, the QC department status and the role of the Quality manager in many organizations is still underestimated and not well appreciated.

Broadbanding of a Single-Feed Planar Antenna for Terrestrial DTV Reception in Mobile Communication

Japanese terrestrial broadcasting was completely converted to digital television (DTV) broadcasting on 470–710MHz as of July 2011. However, fading phenomenon resulting from standing waves is a factor in quality deterioration in TV and mobile communication technologies. Suppression of this is needed for many kinds of technologies. A broadband single-feed planar antenna composed of two antenna components, a Broadband Planar Monopole Antenna (BPMA) and a Broadband Planar Slot Antenna (B-PSA), is proposed for reducing deterioration of reception due to the fading across the DTV band. Reflection coefficients and radiation patterns analyzed by the Finite Difference Time Domain (FDTD) method and compared with measured results indicate that the proposed antenna is broadband compared with a conventional antenna studied previously. A field experiment is conducted in the DTV band. The results of the field experiment indicate clearly that the proposed antenna efficiently suppresses fading resulting from standing waves across the band.

Evaluating Multiobjective Evolutionary Algorithms Using MCDM Methods

The evaluation of multiobjective evolutionary algorithms (MOEAs) involves many metrics, it can be considered as a multiple-criteria decision making (MCDM) problem. A framework is proposed to estimate MOEAs, in which six MOEAs, five performance metrics, and two MCDM methods are used. An experimental study is designed and thirteen benchmark functions are selected to validate the proposed framework. The experimental results have indicated that the framework is effective in evaluating MOEAs.
Non-LTE line-formation for neutral and singly-ionized carbon - Model atom and first results on BA-type stars

A comprehensive model atom for non-LTE line-formation calculations for neutral and singly-ionized carbon is presented. Highly accurate radiative and collisional atomic data are incorporated, recently determined for astrophysical and fusion research using the R-matrix method in the close-coupling approximation. As a test and rst application of the model, carbon abundances are determined on the basis of line-blanketed LTE model atmospheres for ve stars, the main sequence object Vega (A0 V) and the supergiants Leo (A0 Ib), HD 111613 (A2 Iabe), HD 92207 (A0 Iae) and Ori (B8 Iae), using high S=N and high-resolution spectra at visual and near-IR wavelengths. The computed non-LTE line proles t the observations well for a single carbon abundance in each object. For two supergiants, Leo and HD 111613, lines of both species are simultaneously present in the spectra, giving consistent C i and C ii abundances (within the error bars). However, the uncertainties of the abundances are large, on the order of 0.3 dex (statistical + systematical error), thus the ionization equilibrium of C i/ii is of restricted use for the determination of stellar parameters. All supergiants within our sample show a depletion of carbon on the order of 0.2{0.5 dex, indicating the mixing of CN-cycled material into the atmospheric layers, with the sum of the CNO abundances remaining close to solar. This nding is in accordance with recent stellar evolution models accounting for mass-loss and rotation. For Vega, an underabundance of carbon by 0.3 dex is found, in excellent agreement with the similar underabundance of other light elements. The dependence of the non-LTE eects on the atmospheric parameters is discussed and the influence of systematic errors is estimated. Special emphasis is given to the supergiants where a strong radiation eld at low particle densities favours deviations from LTE. Non-LTE eects systematically strengthen the C i/ii lines. For the C i lines in the infrared, a strong sensitivity to modications in the photoionization and collisional excitation data is found. An increasing discrepancy between our model predictions and the observations for the C ii doublet 6578-82 is perceived with rising luminosity, while the other C ii doublet and quartet lines remain consistent. Furthermore, the influence of microturbulence on the statistical-equilibrium calculations is investigated.
HISTORICAL DEVELOPMENT OF THE PRESENT DAY LINEAMENTS OF THE WESTERN ZAGROS FOLD-THRUST BELT: A CASE STUDY FROM NORTHEASTERN IRAQ, KURDISTAN REGION

The part of the Zagros within the Iraqi border occupies an area less than quarter of the country. It includes three tectonic zones which can be clearly identified in the field. These are the Low and High Folded, Imbricated and Thrusted Zones. The main lineaments are the axes of the anticlines; transverse and longitudinal faults; lines of distribution of ophiolite and metamorphic rocks; drainage direction discharge and line of distribution of conglomerates. The direction of axes of the anticlines are trending nearly N38W which normal to the direction of the imposed stress by the Iranian plate front. Due to differences in thicknesses and physical properties of the sedimentary rocks, the axes of these anticlines are not continuous they plunge more or less in an en echelon pattern and in some cases are bend. The lengths of most of these anticlines are around 10-30km. The first appearance of the anticlines in the High Folded Zone possibly started at the Eocene while those of the Thrust Zone initiated at Maastrichtian. Some of these anticlines are cut by transverse faults whose ages are not known. These faults trend nearly normal to the axis of anticlines. Other kinds of lineaments are the distribution of ophiolites and metamorphic rocks. Historically the first appearance of trace of ophiolites (as pebbles in sedimentary rocks) has an age of Lower Maastrichtian. The direction of drainage discharge is nearly towards the south and southwest, which is inherited from that of the Upper Cretaceous and Tertiary paleocurrent directions (sediment transport direction). This direction is related to uplift of the extreme northwestern part of the studied area during Maastrichtian. Evidence for these suggestions is the occurrence of thicknesses of 500m of conglomerates as valley fillings during Late Cretaceous. The depositional axes of the successions was migrated for about 50kms during Cretaceous and Tertiary and becomes younger from northeast towards the southwest as recorded by four narrow belts. The line of migration is nearly coinciding with both directions of present regional slope and the Cretaceous sediment transport. ــــــــــــــــــــــــــــــــــــــــــــــــــــــ
Safety of Mesh for Stress Urinary Incontinence: Fighting the Hype

Mesh surgery for the management of Stress Urinary Incontinence (SUI) has been used effectively and safely since the 1990’s. Despite this, the Therapeutic Goods Association of Australia (TGA) has recently issued a ban on Single Incision Sling (SIS) devices due to a reported increase in post-operative complications. However, SIS devices have been found to have similar efficacy and safety profiles compared to mesh devices that have not been removed from the market. In addition to this, the Food and Drug Administration (FDA) has not issued a ban on any mesh product for SUI, linking the increase in mesh related complications to surgery for pelvic organ prolapse (POP). Mesh surgery via sling devices for SUI has been and continues to be a “gold standard” operation to manage the pathology. The purpose of this commentary is to discuss the successful use of mesh in SUI surgery and highlight the efficacy and safety profile of SIS devices.
