A Research Threshold Efficient Hybrid Encryption Schema for Secure File System

Electronic technologies have radically changed the way of doing business and the way of storing and sharing information. In the technology revolution, security is more affected with the introduction of distributed environment where data requires accessing from remote computers. When Operating Systems (OS) are running on a device with no file encryption, normally file access is controlled through user authentication mechanisms by its own operating system. However, an invader can easily bypass this fence if he gains physical access to the computer. To protect sensitive files/data even if physically accessed the device, the most widely accepted solution to this is to store the files encrypted on the physical media. Windows family of OS uses an EFS, similarly Gnupg is an encryption tool for operating systems such as FreeBSD, Solaris, MacOS to enforce security measure and much more algorithm which are using short length key or keys for encrypting the file-system. Even though these systems are good, still there is a question about confidentiality and privacy because of explosive growth of computing power and cryptanalysis tools and techniques. In this paper a novel approach for encrypting file system using Rbits cipher with PKC is proposed. In brief, Rbits enforce unlimited sub-keying mechanism in encryption process to avoid any sort of cryptanalysis
Modelling PLLs used for frequency generation in radio base stations

PLLs are vital parts of almost all current communication systems. As such, it is of great importance to be able to accurately simulate them. In this thesis PLL theory is explored and simulation is performed using Agilent ADS. The focus is on frequency generating PLLs and related figures of merit such as frequency error, phase error, phase noise and EVM. Theoretical explanations are made as to how it is possible to calculate some of the above figures of merit given a PLL’s phase noise curve. Simulations are performed using behavioural models and are very general in nature. Steady state noise phase noise simulations are performed and results found to agree with theory and other simulation tools. Test benches are provided for transient simulations simulating phenomena such as the appearance of reference spurs, pushing and pulling. The results from the pushing and pulling simulations are not very accurate due to the behavioural components not being able to simulate all imperfections found in a real VCO. In addition to pure PLL simulations, system level simulations are performed on a WCDMA system with a transmitter using a noisy LO (PLL with phase noise) and the resulting EVM is measured. The system simulations show that the PLL’s phase noise has most effect on the EVM in a WCDMA system in the 1000 Hz – 2 MHz frequency range.

The Nebraska Educator

Estimates indicate that about 70 million children in China have been left behind in their hometowns by one or both parents as their parents migrate to other places for work opportunities. However, the potential impact of parental migration on the emotional well-being of left-behind children is still unclear. The purpose of this study was to examine depression levels in Chinese left-behind children and to identify potential risk factors contributing to depressive symptoms in this population. Using a nationally-representative, stratified sample from the China Family Panel Studies (CFPS) database (3019 children, ages 10-15), an HLM model was applied at 1) the child level measuring the influence of family structure and individual-level parenting practices, and 2) the county level estimating the effects of rural vs. urban differences and county-level parenting practices. Cross-level effects between child factors and county factors were also examined. The depressive symptoms were measured by the Center for Epidemiologic Studies Depression (CESD, Radloff, 1977). Findings indicated that the left-behind children were more likely to report higher scores on depressive symptoms indices than children from intact families. Children reporting more positive parenting practices also tended to have fewer depressive symptoms. The effect of family structures on children’s depressive symptoms depended on the county-level parental behaviors. Implications for schools and parenting practices were discussed.
Force Interaction and Sensing in Bio-micromanipulation

Micromanipulation is considered a challenging task which requires high precision motion and measurement at the micro scale. When micromanipulation is concerned with living organisms important considerations need to be addressed. These include the physical or chemical properties of micro-organisms, living conditions, responses to the environment and achieving suitably delicate manipulation. Bio-micromanipulation can include micro surgery or cell injection operations, or to determine interaction forces as the basis to investigate behavior and properties of living micro-organisms. In order to achieve suitable bio-micromanipulation appropriate processes and/or sensory systems need to be investigated. This thesis aims to look into the force interaction and sensing addressing two distinctive challenges in the field of bio-micromanipulation. To this end, this thesis presents two major contributions to advancing bio-micromanipulation. Firstly, a novel Haptic Microrobotic Cell
Inverter control systems in the residential heat pump air conditioner

A compressor capacity control with an inverter has been considered from the viewpoint of high energy saving in a refrigerating cycle. However, the system has not been put into practical use because of high initial cost, technical problems of electronic parts, and complexity of system control. In this connection, we developed the new inverter-controlled heat-pump air conditioner by using the latest electronics and refrigeration technology. This paper discusses the trend of energy saving in air conditioners in Japan and the objectives of developing the inverter controlled air conditioner. It also discusses the following items with respect to the inverter controlled air conditioner and the effects of employing an inverter: 1. Inverter for air conditioning; 2. Refrigeration cycle; 3. Air conditioner control with inverter.
Demonstration of efficient p-type doping in Al/sub x/Ga/sub 1-x/N/GaN superlattice structures

Enhanced acceptor activation, reduced acceptor binding energy and enhanced conductivity are demonstrated in AlxGa1–xN/GaN doped superlattice structures. An acceptor activation energy of 58 meV is demonstrated in an Al0.20Ga0. 80N/GaN superlattice structure with a period of 200 A. This value is significantly lower than the 200 meV activation energy measured in bulk GaN. The dependence of activation energy on the Al content of the superlattice is consistent with that predicted by the theoretical model. The demonstration of improved p-type doping characteristics in GaN is expected to enable the realisation of electronic and optoelectronic devices with improved properties.
When were the straits between the Baltic Sea and the Kattegat inundated by the sea during the Holocene?

The timing of the flooding of the Danish/German/Swedish straits and the first marine influence in the Baltic Basin after the Ancylus Lake stage has been much debated. Here we present 47 new radiocarbon ages from sediment cores retrieved from Danish waters, ages that record the marine transgression of the area. Most of the ages are based on shells of marine molluscs, hence the ages are uncertain because we do not know the precise reservoir age in the past. We use a reservoir age of 400 years, which is based on dating of museum specimens collected live before testing of nuclear bombs. It appears from the ages that the Great Belt (Storebælt) was inundated before The Sound (Øresund). The oldest ages on marine shells from the northern part of the Great Belt region are about 8.9 cal. ka BP. From the central part of the Great Belt, the oldest ages are about 8.2 cal. ka BP, in Mecklenburg Bay 8.1 cal. ka BP and in the Arkona Basin 7.1 cal. ka BP. Sediments deposited prior to the occurrence of marine molluscs contain brackish‐water ostracods (Cyprideis torosa and Cytheromorpha fuscata); the sediments are usually laminated and non‐bioturbated mud. The brackish‐water phase may have lasted 500–1000 years. The youngest lake deposits without signs of marine influence are dated to c. 8.8 cal. ka BP (central Great Belt), 8.7 cal. ka BP (Little Belt) and 8.5 cal. ka BP (Arkona Basin). We see no evidence for marine influence at c. 10 cal. ka BP as recorded by some studies from the Baltic Basin.

Surface and chemical characteristics of platinum modified activated carbon electrodes and their electrochemical performance

Platinum (Pt) loaded activated carbons (ACs) were synthesized by the thermal decomposition of platinum (II) acetylacetonate (Pt(acac)2) over chemically activated glucose-based biochar. The effect of Pt loading on surface area, pore characteristics, surface chemistry, chemical structure, and surface morphology were determined by various techniques. XPS studies proved the presence of metallic Pt0 on the AC surface. The graphitization degree of Pt loaded ACs were increased with the loaded Pt0 amount. The electrochemical performance of the Pt-loaded ACs (Pt@AC) was determined not only by the conventional three-electrode system but also by packaged supercapacitors in CR2032 casings. The capacitive performance of Pt@AC electrodes was investigated via cyclic voltammetry (CV), galvanostatic charge-discharge curves (GCD), and impedance spectroscopy (EIS). It was found that the Pt loading increased the specific capacitance from 51 F/g to 100 F/g. The ESR drop of the packaged cell decreased with the Pt loading due to the fast flow of charge through the conductive pathways. The results showed that the surface chemistry is more dominant than the surface area for determining the capacitive performance of Pt loaded AC-based packaged supercapacitors.
Qualité de la conception de tests logiciels: plate-forme de conception et processus de test

Nowadays, car electronics become more and more complex and represents more than 30% of the total cost of a car. For instance, in a 2008 BMW 5 series model, one can find up to 80 electronic modules communicating together and representing 10 million lines of software code. Facing this growing complexity, carmakers and automotive electronic suppliers are looking for efficient methods to develop, verify and validate electronic modules. In fact, they focus on the software part of these modules since it accounts for more than 80% of the total number of problems detected on these modules. In this context, we achieved our research project with the aim of proposing a global approach able to improve the quality of automotive embedded software. We started with an audit of the software practices currently used in automotive industry and we pinpointed potential levers to improve the global software quality. Based on the results of the audit and the literature review related to software quality, we developed a global approach to improve the design of test cases for software products. In fact, we developed a test generation platform to automatically generate test cases for a software product. It is mainly based on modeling the software functional requirements in order to be simulated when testing the software, focusing on critical tests to be done (because of their higher probability to detect a bug) and monitoring the automatic generation of tests by quality indicators such as the structural and functional coverage but also the tests cost. The generation of critical tests is based on the definition of real use profiles by software product and on the reuse of bugs and test cases capitalized on previous projects. Besides the computational aspects of software testing, our approach takes into account organizational matters such as knowledge management, competency management and project management. Our approach have been implemented in a computer platform and experimented on two typical case studies of an automotive electronic supplier, with historical test data. The results of our experiments reveal significant improvement in software quality: more bugs are detected earlier and in less time.
Pan‐European phylogeography of the European roe deer (Capreolus capreolus)

Abstract To provide the most comprehensive picture of species phylogeny and phylogeography of European roe deer (Capreolus capreolus), we analyzed mtDNA control region (610 bp) of 1469 samples of roe deer from Central and Eastern Europe and included into the analyses additional 1541 mtDNA sequences from GenBank from other regions of the continent. We detected two mtDNA lineages of the species: European and Siberian (an introgression of C. pygargus mtDNA into C. capreolus). The Siberian lineage was most frequent in the eastern part of the continent and declined toward Central Europe. The European lineage contained three clades (Central, Eastern, and Western) composed of several haplogroups, many of which were separated in space. The Western clade appeared to have a discontinuous range from Portugal to Russia. Most of the haplogroups in the Central and the Eastern clades were under expansion during the Weichselian glacial period before the Last Glacial Maximum (LGM), while the expansion time of the Western clade overlapped with the Eemian interglacial. The high genetic diversity of extant roe deer is the result of their survival during the LGM probably in a large, contiguous range spanning from the Iberian Peninsula to the Caucasus Mts and in two northern refugia.
Diagnostic acuuracy of cerebrospinal fluid and serum-isolated exosomes for glioblastoma: a systematic review and meta-analysis

Glioblastoma (GBM) is the most malignant glioma cancer with a high morbidity and mortality worldwide. Unfortunately, a routine method is not available for screening or preoperative early detection of GBM. However, early detection in a none-invasive or minimally invasive method could be beneficial and increase the survival rate. In this systematic review and meta-analysis, we aimed to examine the diagnostic accuracy of exosomal RNAs that were extracted from patients’ CSF or serum for GBM diagnosis. We searched Web of Science, Scopus, PubMed (including Medline), Embase and ProQuest (as databases for grey literature) up to December 2019; we also performed backward and forward reference checking of included and relevant studies. Finally, included studies were assessed with QUADAS-2 checklist and their data extracted. We carried out a meta-analysis of included study, regarding to the diagnostic meta-analysis guidelines for obtaining pooled accuracy estimates. In addition, sensitivity analysis and meta-regression were also conducted. We retrived 1730 records from databases, nine of them included in systematic review and qualitative synthesis. Six studies were considered to statistical analysis and performed diagnostic meta-analysis. Our results suggested that the pooled sensitivity and specificity of exosomal biomarkers for GBM were 0.76 and 0.80, respectively. In addition, the pooled positive likelihood ratio (PLR), negative likelihood ratio (NLR), and diagnostic odds ratio (DOR) were 3.7, 0.30 and 12, respectively. The overall area under the curve (AUC) of exosomal biomarkers for GBM diagnosis was found to be 0.85. According to our results, the value of 0.85 for AUC, suggesting that exosomal biomarkers might serve as a high potential and non-invasive diagnostic tool for GBM.
Computational Modelling of Unsteady Aircraft Aerodynamics Flows

This paper reviews simulations using Computational Fluid Dynamics (CFD) of unsteady flow applications relevant to aircraft aerodynamics. Key elements of the CFD methodology are described which include a description of parallel multiblock (PMB), the in-house unsteady viscous flow code and the powerful cluster computing environment that has been constructed to tackle demanding problems successfully. The flow cases described include transonic flow over a cavity, the pulsating flow over a spiked blunt body, vortical flow over a manoeuvring delta wing, surge wave in an engine intake duct and dynamic stall over an aerofoil. The paper demonstrates the powerful nature of CFD in helping to understand unsteady flow processes.

Rational Design and Identification of Harmine‐Inspired, N‐Heterocyclic DYRK1A Inhibitors Employing a Functional Genomic In Vivo Drosophila Model System **

Deregulation of dual‐specificity tyrosine phosphorylation‐regulated kinase 1A (DYRK1A) plays a significant role in developmental brain defects, early‐onset neurodegeneration, neuronal cell loss, dementia, and several types of cancer. Herein, we report the discovery of three new classes of N‐heterocyclic DYRK1A inhibitors based on the potent, yet toxic kinase inhibitors, harmine and harmol. An initial in vitro evaluation of the small molecule library assembled revealed that the core heterocyclic motifs benzofuranones, oxindoles, and pyrrolones, showed statistically significant DYRK1A inhibition. Further, the utilization of a low cost, high‐throughput functional genomic in vivo model system to identify small molecule inhibitors that normalize DYRK1A overexpression phenotypes is described. This in vivo assay substantiated the in vitro results, and the resulting correspondence validates generated classes as architectural motifs that serve as potential DYRK1A inhibitors. Further expansion and analysis of these core compound structures will allow discovery of safe, more effective chemical inhibitors of DYRK1A to ameliorate phenotypes caused by DYRK1A overexpression.
Valuing externalities of Bangkok's Mass Transit (Skytrain) System

The Bangkok Transit System (BTS) is a 23.5 kilometre elevated heavy rail system in the central area of Bangkok that was opened in 1999. Recent patronage has been about 280,000 trips per weekday, which is a little under half of that originally forecast and is a little over 60 percent of its currently estimated patronage potential. The system has provided significant benefits for its users and the community. Door-to-door travel time for many people using the system is about half of that by former transport modes. The environmental benefit resulting from the reduction in road traffic is substantial. The diversion of former road-based trip to the BTS released road capacity that allowed additional travel to be generated with associated increased emissions and also with economic and social benefits to the community. The paper outlines the features and travel demand impacts of the BTS, and describes an evaluation that quantified the external benefits of the BTS to road users and to the community at large. The evaluation gave specific consideration to the effect of generated road traffic on these benefits. (a) For the covering entry of this conference, please see ITRD abstract no. E209537.
Identification of Mycoplasma hyorhinis P37 protein-specific B cell linear epitopes using monoclonal antibodies against baculovirus-expressed P37 protein

Background Mycoplasma hyorhinis (Mhr) is the etiologic agent of lameness and polyserositis in swine. Mhr P37 is a membrane protein that may play a critical role in immunity. It is a potential target for diagnostic development, but there is little information concerning its B cell epitopes. To investigate the epitopes of Mhr P37, a recombinant protein was developed in a baculovirus system using monoclonal antibodies (mAbs) prepared against P37 protein. Results Western blot and indirect immunofluorescence assays (IFA) confirmed that the expressed P37 protein was recognized by Mhr-positive porcine and mouse sera. Furthermore, the P37 protein was purified using affinity chromatography and used to immunize mice for hybridoma cell fusion. Four mAbs were found to be positive for Mhr. A panel of truncated P37 proteins was used to identify the minimal B cell linear epitopes of the protein based on these mAbs. The core epitope was determined to be 206KIKKAWNDKDWNTFRNF222. Conclusions This study identified mAbs that could provide useful tools for investigating the antigenic structure and function of the Mhr P37 protein as well as its application to diagnostic techniques.
Design of a Combined Tripler-Subharmonic Mixer at 330 GHz for Multipixel Application Using European Schottky Diodes

We present the development of an integrated heterodyne receiver at 330 GHz featuring a balanced tripler and a sub-harmonic mixer embedded on the same substrate. The receiver block has one face dedicated to the feed aperture, and the opposite face to the local oscillator input and the intermediate frequency output. By utilizing only opposite faces this configuration makes building of a full two-dimensional array possible through stacking receiver elements. Moreover, the size of the receiver block is minimised by a small spacing between the mixer and its local oscillator circuit. The input signal of the multipler stage is between 55 and 60 GHz where high power sources are more commonly available than at sub-millimeter frequencies. A preliminary design and its analysis are described in order to enlight problematics related to circuits composed of several non-linear elements. Packaging constraints are also discussed here since the spacing between two horn antennas is limited by the physical size of the local oscillator and IF connectors on the back face of the pixel.
Security Attacks in S-WBANs on IoT based Healthcare Applications

The internet exists as a global interconnection network for information sharing, commerce, and entertainment. The usage of internet has grown tremendously over the past decade in the field of E- health care monitoring system. In Ehealth care monitoring systems, Smart Wireless Body Area Networks (S-WBANs) is one among such technologies and is being explored. S-WBANs are primarily used as a smart object with computer-assisted rehabilitation. They serve as a remote monitoring service in smart electronic healthcare to continuously measure the vital parameters like heart rate, insulin level, body temperature, etc. They are thereby providing doctors with early detection of a patient’s medical conditions. However, sharing of sensitive personal data over a wireless network requires a high level of security. Since any breach in the system security will lead to a direct violation of the patient’s privacy. In order to address the security vulnerability of the existing system, in this paper a block chain based Smart Wireless Body Area Networks has been proposed to provide better security with enhanced privacy and access control for E- health care monitoring system. Moreover, the proposed system enhances the scalability and provides mitigation against all the security attacks in IoT Environment.
