Linear spring sti nesses for two-dimensional nite element modeling of ff fi arteries

The physical properties of arteries are important in the research of the circulatory system dynamics. Moreover, in order to build Virtual Reality Simulators, it is crucial to have a tissue model able to respond in real time. A reduced mesh size results in shorter processing times, which can be achieved using a two-dimensional grid. In this work, a triangular topology is considered and the nodes are connected by three kinds of linear springs (one normal and two angular ones). The spring sti nesses depend on the mesh geometry and on the elastic properties ff of the artery. The model linearizes the material response, but it still contemplates the geometric nonlinearities. Comparisons showed a good match with a nonlinear model and with our previous model based on a quadrilateral topology. However, the proposed model extension is more exible and easier to implement than the fl previous one.
Schedulability Analysis of CAN based Systems with Precedence Constraints

We present a schedulability analysis of CAN based system. Existing analyses consider that the worst-case occurs when all task (and messages) are released simultaneously (pessimistic assumption). In this paper, a systematic approach to precedence analysis is presented, considering the interference between task sequences instead of interference between single tasks. We also apply this analysis to a DX bus (a CAN based commercially available wheelchair controller), and we compare its predictions with those of a classical analysis. Results show that we obtain more precise estimations (≈14%)
Detection of Human Herpesvirus 8 DNA Sequences before the Appearance of Kaposi ' s Sarcoma in Human Immunodeficiency Virus ( HIV )-Positive Subjects with a Known Date of HIV

The presence of human herpesvirus 8 (HHV-8) DNA sequences was sought by polymerase chain reaction (PCR) in peripheral blood mononuclear cells of 4 groups: 6 human immunodeficiency virus (HIV)-infected persons with well-defined dates of seroconversion, during the period between the diagnosis of HIV infection and the appearance of Kaposi's sarcoma (KS); 45 HIV-positive persons with no symptoms of HIV infection; 11 AIDS patients with KS; and 14 AIDS patients without KS. HHV-8 DNA PCR was positive in 3 of the 6 patients during HIV infection preceding the appearance of KS and in all but 1 of 11 AIDS patients with KS. HHV-8 DNA PCR was negative in all but 1 of the 45 HIV -positive persons with no symptoms of infection and in all but 1 AIDS patient without KS. These results indicate that HHV-8 DNA may be detected several years before the occurrence of KS in HIV-infected subjects.

This paper is concerned with the problem of robust output tracking of single -input and single-output nonlinear systems with partially known uncertainties. Based on Lyapunov method and input/output linearization approach for nonlinear state feedback synthesis, a class of continuous adaptive robust state feedback controllers which can guarantee asymptotic stability instead of uniform ultimate boundedness for the trajectory error system of nonlinear systems with uncertainties. Finally, an illustrative example is given to demonstrate the utilization of the results. Key-Words: robust output tracking, uncertain nonlinear systems, input/output linearization, Lyapunov method
X-RAY SPECTRAL ANALYSIS OF THE STEADY STATES OF GRS 1915+105

We report on the X-ray spectral behavior within the steady states of GRS1915+105. Our work is based on the full data set of the source obtained using the Proportional Counter Array (PCA) on the Rossi X-ray Timing Explorer (RXTE) and 15 GHz radio data obtained using the Ryle Telescope. The steady observations within the X-ray data set naturally separated into two regions in the color–color diagram and we refer to these regions as steady-soft and steady-hard. GRS1915+105 displays significant curvature in the coronal component in both the soft and hard data within the RXTE/PCA bandpass. A majority of the steady-soft observations displays a roughly constant inner disk radius (Rin), while the steady-hard observations display an evolving disk truncation which is correlated to the mass accretion rate through the disk. The disk flux and coronal flux are strongly correlated in steady-hard observations and very weakly correlated in the steady-soft observations. Within the steady-hard observations, we observe two particular circumstances when there are correlations between the coronal X-ray flux and the radio flux with log slopes h ~  0.68 0.35and h ~  1.12 0.13. They are consistent with the upper and lower tracks of Gallo et al. (2012), respectively. A comparison of the model parameters to the state definitions shows that almost all of the steady-soft observations match the criteria of either a thermal or steep power-law state, while a large portion of the steady-hard observations match the hard-state criteria when the disk fraction constraint is neglected.
Punzo, Giuliano and MacLeod, Charles and Baumanis, Kristaps and Summan, Rahul and Dobie, Gordon and Pierce, Stephen and Macdonald, Malcolm (2018) Bipartite guidance, navigation and control architecture

In this work the autonomous flight of a drone for inspection of sensitive environments is considered. Continuous monitoring, the possibility of override and the minimisation of the on-board computational load are prioritized. The drone is programmed with a Lyapunov vector guidance and nonlinear control to fly a trajectory passed, leg after leg, by a remote ground station. GPS is the main navigation tool used. Computational duties are split between the ground station and the drone’s on board computer, with the latter dealing with the most time critical tasks. This bipartite autonomous system marries recent advancements in autonomous flight with the need for safe and reliable robotic systems to be used for tasks such as inspection or structural health monitoring in industrial environments. A test case and inspection data from a test over flat lead roof structure are presented.
International Conference on Ultrarelativistic Nucleus-Nucleus Collisions ( Quark Matter 2018 ) Jet suppression and jet substructure in Pb + Pb and Xe + Xe collisions with the ATLAS detector

This short summary presents latest measurements of the nuclear modification factor, RAA, for R = 0.4 jets in Pb+Pb collisions at √ sNN = 5.02 TeV with the ATLAS detector at the LHC. The analysis is performed over a large range of transverse momentum, up to pT = 1 TeV, and differentially in jet pT, rapidity, and collision centrality. The jet RAA is measured also differentially in the jet mass, m, which provides new information on the dependence of the energy loss on the substructure of jets. Latest results by ATLAS on the dijet momentum balance in Xe+Xe collisions at √ sNN = 5.44 TeV are presented and compared to the same quantity measured in Pb+Pb collisions at √ sNN = 5.02 TeV. These recent measurements should help us understand mechanisms of parton energy loss and properties of hot and dense matter created in heavy-ion collisions.
Cancer-Associated Venous Thromboembolic Disease , Version 2 . 2018 Featured Updates to the NCCN Guidelines

Venous thromboembolism (VTE) is common in patients with cancer and increases morbidity and mortality. VTE prevention and treatment are more complex in patients with cancer. The NCCN Guidelines for Cancer-Associated Venous Thromboembolic Disease outline strategies for treatment and prevention of VTE in adult patients diagnosed with cancer or in whom cancer is clinically suspected. These NCCN Guidelines Insights explain recent changes in anticoagulants recommended for the treatment of cancer-associated VTE.

Alogla, A.f. and Amalou, F. and Balmer, C. and Scanlan, P. and Shu, W. and Reuben, R.L. (2015) Micro-tweezers : design, fabrication, simulation and testing of a pneumatically actuated micro-gripper for micromanipulation and microtactile sensing. Sensors and Actuators

This paper presents a novel micro-gripper design with the dual functions of manipulation and force sensing. The device consists of two parallel plates, each mounted on torsion bars, which can be made to rotate towards or away from each other by use of a pneumaticallyor hydraulically-actuated elastic membrane. The plates can be conveniently fabricated using photo-etching and the design allows for a range of ratios between actuation pressure and tip opening displacement and force. The elastic gripping tips can be designed to provide sufficient compliance that their strain can be used to monitor and control the gripping force. An exemplar device has been fabricated and its behaviour characterised by a series of mechanical measurements of force and displacement. These measurements have been rationalised using a simple analytical model, backed up with finite element analysis to emphasise the design variables and scalability. This exemplar device, with a maximum tip opening amplitude of 1 mm and maximum force output of 50 mN, has also been demonstrated to perform pick-and-place operations with 200 m micro-beads. © 2015 The Authors.

Sample-size determination and adherence in randomised controlled trials published in anaesthetic journals

Background: Sample-size calculations are critical to ensure that randomised control trials return robust and reliable results. The estimated treatment effects used in these calculations is often significantly different from the actual treatment effect and can dramatically impact trial validity. Methods: This study examined sample-size calculations in randomised controlled trials designed to show superiority between two-arm parallel groups with a single primary outcome that were published in the top five anaesthetic journals for 2014 (as per Thomson Reuters impact factors). In particular, it sought to determine treatment effect estimations used in a priori sample-size calculations and compare them with actual treatment effects. Results: A PubMed search identified 209 possible articles; 52 were drawn for full text review; and 28 were included in the final analysis. The relative difference between expected and actual event rates was greater than 20% in 80% of trials and greater than 50% in 44% of trials. Conclusions: Unrealistic assumptions of treatment effects in randomised controlled trials published in anaesthesia journals are common. Trial sample sizes should be calculated thoughtfully and realistically and should be fully reported in both trial protocols and publications. Researchers should be aware of the opportunity cost as well as the possible dangers to patients when unrealistic assumptions are made. Where possible researchers should collaborate to achieve meaningful trial sample sizes to ensure robust clinical findings.
Adult Cognitive Development from a Lifespan Developmental Perspective

A fairly concise lifespan perspective is presented on what some would call normal cognitive aging. The currently most useful theoretical frameworks that include statements about cognitive development from young adulthood to advanced old age are outlined. Psychologists are reminded that they must never confuse age differences that may largely represent cohort differences associated with rapidly changing environmental circumstances, with age changes that occur within individuals over their life course. A distinction is next made between normal and pathological aging, as is characterized by very different aging trajectories that distinguish individuals who follow average trajectories, those who decline early, those who develop neuroor psycho-pathologies, and those favored few “super-aged” who remain fully functional until shortly before their death. Because changes in intellectual competence represent a central topic in the psychology of aging, examples of substantive data for such changes are then presented through adulthood. Little cognitive decline not associated with pathological processes is found prior to the decade of the 60s, but some genetically and environmentally disadvantaged individuals show decline in the late 40s or early 50s. Age difference data and differential cohort paths are also presented for different abilities over the past 70 years. Finally, I refl ect on the topic of ageism in the psychology of aging and suggest that the major infl uence for much professional stereotyping of the elderly may be found in the assumption of universal cognitive decline and movement towards negative personality traits with increasing age. I show data that suggest such decline is not universal although larger proportions of older persons show decline for each successive decade after the 60s are reached.
Title Does an R & D Tax Credit Affect R & D Expenditure ? The Japanese Tax Credit Reform in 2003

To what extent does a tax credit affect firms’ R&D activity? What are the mechanisms? This paper examines the effect of the 2003 Japanese tax credit reform on firms’ R&D investment by exploiting cross-sectional variation across firms in the changes in the effective tax credit rate between 2002 and 2003. When we use the benchmark sample to estimate the first-difference equation between 2002 and 2003, our estimate for the elasticity of R&D investment with respect to the effective tax credit rate is 2.05% with a standard error of 0.60, and the estimated effect of the R&D tax credit on R&D investment is significantly larger for small firms with relatively large outstanding debts. When we use different methods and different samples, we find mixed evidence for the positive effect of the R&D tax credit, but an interaction term between the effective tax credit rate and the debt-to-asset ratio is always estimated to be significant for small firms, providing robust evidence for the role of financial constraint in determining the effect of the R&D tax credit.

Application of Machine Learning Techniques to Paper-Author Identification Problem

Author name ambiguity is known to be one of the major challenges faced by academic search engines covering large numbers of publications: while several different authors can have similar or even identical names, each author may also publish using different names, both of which potentially causing publications to be associated with incorrect authors. Fortunately, with informative features such as title and keywords of each paper, names of conferences or journals related to papers, and name(s) and affiliation(s) of each author, as well as some ground-truth consisting of a set of known correct paper-author associations and a set of known incorrect ones, the problem of attributing publications to their correct authors can be addressed with a variety of machine learning approaches, and the purpose of this project is to compare the performance of these approaches.
Long-term stability of dithionite in alkaline anaerobic aqueous solution 1

Closed-system experiments were conducted to invest igate the decomposition of sodium 10 dithionite in aqueous solutions under varying pH an d starting concentrations to simulate the 11 deployment of dithionite as an in-situ redox barrie r. Co-determination of dithionite and its 12 degradation products was conducted using UV-Vis spe ctrometry, iodometric titration, and ion 13 chromatography. In unbuffered solutions, dithionite reacted rapidly, whereas in near-neutral 14 solutions (pH ~7), it persisted for ~ 50 days and i n alkaline solution (pH ~9.5) for >100 days. 15 These are the longest lifetimes reported to date, w hich we attribute to not only excluding oxygen 16 but also preventing outgassing of H 2S. Thoroughly constraining the reaction products ha s led to 17 the following hypothesized reaction: 18
Bacillus cereus KLUVAA Mediated Biocement Production Using Hard Water and Urea

In the present study, a potential bacterial strain with maximum urease activity was isolated from urea-rich paddy field soil for biocement production. The bacterial isolate was screened using Christensen selective agar media and named as KLUVAA. This isolate was found to be tolerant up to 10 % urea. 16S rRNA sequencing analysis identified the isolate KLUVAA as Bacillus cereus. Biocement production was carried out using tap water with 431.7 mg L–1 of hardness as a natural source of calcium. Functional groups present in biocement were analysed using FT-IR spectrum. The morphology and elemental composition of the biocement was studied using SEM with EDS mapping and XRD analyses. Thermogravimetric analysis was used to study the thermal stability of the microbial biocement. Further, process parameters were optimized for enhancing the yield of biocement.
You Wanna Consider a Constructional Approach towards Wanna-contraction ?

Studies of wanna-contraction within the Chomskyan framework (Chomsky 1981) have often focused on syntactic constraints to explain its distribution (see, e.g., Zwicky 1970, Chomsky and Lasnik 1978, Boeckx 2000). For example, while wanna-contraction may occur in contexts such as (1), it is generally assumed to be blocked by syntactic elements such as WH-traces in (2), by infinitival clauses in (3), and by prepositional to in (4). 1
iversity of zoonotic enterohepatic Helicobacter species and etection of a putative novel gastric Helicobacter species in ild and wild-born captive chimpanzees and western wland gorillas

A number of Helicobacter species cause gastrointestinal or hepatic disease in humans, including H. pylori, gastric non-H. pylori helicobacters from animal origin and enterohepatic Helicobacter species. Little is known on the presence of Helicobacter species in great apes, our closest living relatives and potential reservoirs of microorganisms that might emerge in humans. The aim of the present study was to investigate the presence of gastric and enterohepatic Helicobacter species in African chimpanzees and gorillas. Fresh fecal samples were collected from wild endangered chimpanzees and critically endangered western lowland gorillas from different African National Parks, as well as wild-born captive animals from primate sanctuaries. Intact Helicobacter bacteria were demonstrated in feces by fluorescence in situ hybridization. Screening using a Helicobacter genus-specific PCR revealed the presence of Helicobacter DNA in the majority of animals in all groups. Cloning and sequencing of 16S rRNA gene fragments revealed a high homology to sequences from various zoonotic enterohepatic Helicobacter species, including H. cinaedi Corresponding author.

Evaluating Requirements Methods based on User Perceptions : A Family of Experiments

Numerous methods and techniques have been proposed for requirements modeling, although very few have had widespread use in practice. One drawback of requirements methods is that they lack proper empirical evaluations. This means that there is a need for evaluation methods that consider both the theoretical and practical aspects of this type of methods and techniques. In this paper, we present a method for evaluating the quality of requirements modeling methods based on user perceptions. The method consists of a theoretical model that explains the relevant dimensions of quality for requirements methods, along with a practical instrument with which to measure these quality dimensions Basically, it allows us to predict the acceptance of a particular requirements method in practice, based on the effort of applying the method, the quality of the requirements artifacts produced, and the user perceptions with regard to the quality of the method. The paper also presents an empirical test of the method that has been proposed for evaluating a Rational Unified Process (RUP) extension for requirements modelling. That test was carried out through a family of experiments conducted with students and practitioners and provides evidence of the usefulness of the evaluation method proposed.
Performance of Massive MIMO Systems with Transceiver Hardware impairments

Massive MIMO (multiple-input multiple-output) provides great improvements in spectral efficiency (SE) over legacy cellular networks, by coherent combining of the signals over a large antenna array and by spatial multiplexing of many users. Since its inception, the coherent interference caused by pilot contamination has been believed to be an impairment that does not vanish, even with an unlimited number of antennas. In this paper we study and evaluate the effect of transceiver impairments in massive MIMO Systems and pilot contamination. Also this paper discuss downlink, uplink massive MIMO system and prove that with LMMSE estimator, the SE grows without bound as the number of antennas increases, even under pilot contamination, under a condition of linear independence channels matrices.
A New Clustering Based Routing Algorithm for NoC

With the increasing number of the integrated cores on a single chip, research into Network on Chip (NoC) becomes important. NoC has been proposed as a solution to replace the classic interconnections of Systems on Chip (SoCs) design. Topology and routing algorithm are important keys of the NoC design. In this paper, we propose a new fault-tolerant routing algorithm for Networks on Chip (NoCs). The proposed algorithm is based on a combination between a dynamic routing algorithm and a communication load clustering technique in a 2D mesh topology.
Determination of Sucrose and Glucosylglycerol in Intracellular Extracts of Cyanobacteria by Anion Exchange Chromatography

A high performance anion-exchange chromatography with pulsed amperometric detection is developed for the determination of sucrose and glucosylglycerol in cyanobacterial cells. Under the optimized conditions, showed good linearity (r 2 >0.9999) with the chromatographic peak area in the range between 0.1 and 50.0 mg/L. The Limit Of Detection (LOD) is 0.15 mg/L for sucrose and 0.03 mg/L for glucosylglycerol. RSDs of the detection results are less than 2.0% (n = 8). The result showes that the method is convenient and accurate for the determination of sucrose and glucosylglycerol in cyanobacterial cells.
