Regulation of lipid levels after ischemic stroke and an analysis of the associated factors in China

Background and Objectives: Stroke is the most common neurological disease in China and regulation of lipid levels is important for secondary prevention. This study aimed to investigate the practice of lipid lowering agents immediately after and one month following ischemic stroke in China, and to determine the factors affecting the practice. Methods: A total of 857 patients with acute ischemic stroke were enrolled from 11 hospitals in the Qingdao area, Northern China. Data pertaining to the patients’ demographic, clinical data, and treatment before and after the stroke were recorded. Univariate and multivariate logistic regression analyses were used to determine the factors associated with the treatment at two time points: at the acute stage and at one month follow-up. Results: The frequency of lipid lowering therapy was 50.3% (431/857) at acute stage and 41.5% (306/738) at one month. Lipid lowering therapy at acute stage was independently and positively associated with a history of hyperlipidemia((P=0.002, OR (95%CI): 3.784 (1.610-8.898)) and excess alcohol consumption (P=0.005, OR (95%CI): 1.928 (1.214-3.062)), partial anterior circulation infarct classifi cation (P=0.000, OR (95%CI): 1.974 (1.370-2.767)), and low-density lipoprotein levels ((P=0.000, OR (95%CI): 1.426 (1.170-1.739)). Lipid lowering therapy at one month follow-up was independently and positively associated with lipid lowering therapy at acute stage ((P=0.000, OR (95%CI): 18.275 (11.47629.101)), and negatively with the Modifi ed Rankin Scale ≥4 at follow-up ((P=0.030, OR (95%CI): 0.568 (0.341-0.948)). Conclusions: Lipid lowering therapy was found to be used in about half of patients during acute and early secondary prevention of ischemic stroke in the Qingdao area of Northern China. There should be more education efforts to the health care professionals and public to increase its use.
Heat transfer characteristics of slip flow over solid spheres

In this study, heat transfer characteristics of slip flow over an isolated impermeable solid sphere are investigated numerically. An isothermal solid sphere is considered at intermediate Reynolds numbers (0 ≤ Re ≤ 50) for Prandtl numbers in the range of 0.7–7.0. The Navier–Stokes and energy equations are solved by a control volume technique in conjunction with the velocity slip and temperature jump boundary conditions. It was found that the size of the thermal wake region according to the Knudsen number depends on the Prandtl number. At lower Prandtl numbers (0.7 ≤ Pr ≤ 2.0), the thermal wake region shrinks as the Knudsen number increases, while at higher Prandtl numbers, it grows as the Knudsen number increases. The maximum temperature jump occurs at the front stagnation point where the local Nusselt is itself maximum, owing to the maximum temperature gradient at this point. The results show that due to the opposing effects of the velocity slip and temperature jump, the average Nusselt number variation with the Knudsen number depends nonlinearly on both the Prandtl and Reynolds numbers. Furthermore, for the limiting case of Re → 0, an analytical solution for the problem is presented which has also served as a validation case.
TARGET SEPARATION AND CLASSIFICATION USING 11 . B 2 CLOUD RADAR DOPPLER-SPECTRA

Cloud radar signals are caused by a number of targets such as cloud droplets, drizzle, rain, ice particles, snow, hail, plankton (Insects and other non meteorological targets), ground clutter, and maybe others. Sometimes signals from different targets coincide in spectra from single range gates but due to their different Doppler velocities they can be separated in many cases. For interpreting the cloud radar data (e.g. to derive cloud boundaries or micro physical parameters) it is essential to know which parts of the signals are caused by which target types.
Output feedback stabilization of time-delay switched linear systems

Abstract This paper deals with the stabilization issue of switched linear systems with time-delays. Based on previous results related to switched linear systems with no time-delays and on the concept of piecewise quadratic Lyapunov-Krasovskii functionals, we solve the problem of searching output feedback switching laws ensuring stability. Our synthesis method is based on the solution of a set of matrix inequalities associated with the modes of the switched system.
A 0.007-${\rm mm}^{2}$ 108-${\rm ppm}/^{\circ } {\rm C}$ 1-MHz Relaxation Oscillator for High-Temperature Applications up to 180

Reliable high-temperature CMOS oscillators are required for clock or time-base generation in several applications including data acquisition for aerospace, automotive control, oil field instrumentation, and pulp and paper digesters. In this paper, we present low-complexity resistive and capacitive temperature-compensation techniques for CMOS relaxation oscillators. In such oscillators, the frequency of oscillation is a function of a resistor-capacitor product. The resistive compensation technique employs a recently proposed monolithic resistor with a given temperature coefficient (TC) that uses contacts to adjust the TC of the resistor. The capacitive compensation technique is based on using a varactor to adjust the value of the timing capacitance over temperature to compensate for the high-temperature junction leakage current and to keep the oscillation frequency relatively constant. A prototype oscillator based on the proposed techniques is implemented in a standard 0.13-μm CMOS process and reliably operates over 25 to 180 °C. Measured results show that over the temperature range of interest the compensated oscillator achieves a temperature coefficient of 108 ppm/°C. The oscillator along with its output drivers occupies 7200 μm2 (2.3 × to 114 × smaller than state-of-the-art designs) and consumes 428 μW from a 2.5 V supply. For supply variations between 2 and 3 V, the frequency variation is ±1.09%/V.
Examining the Impact of Visitors’ Emotions and Perceived Quality towards Satisfaction and Revisit Intention to Theme Parks

Theme parks attempt to create enjoyable and amazing experiences for visitors. As a result, theme parks are important sectors within the tourism industry, which has grown dramatically with theme parks becoming the main tourist destinations in some countries. The purpose of this research is to analyze how the perceived quality and emotions of visitors in Malaysia’s theme park environments influence their satisfaction and behavioral intentions to revisit. Three main factors that will influence visitors’ satisfaction towards theme parks and their behavioral intentions to revisit are perceived quality, arousal-based experiences and pleasure-based experiences. This study involves 320 respondents, employing a questionnaire survey as the main method of data collection. The results of the study indicate that two significant predictors that influence the satisfaction among the theme park visitors are arousal-based experiences and perceived service quality. The theme parks’ managements can use the findings of this study in planning and executing marketing strategies to improve the theme park service offerings.
Corruption and Oil : Evidence from Panel Data

It has been argue that issues of corruption may be particularly relevant in the context of natural resources, as natural resource exploration is an extremely high rent activity likely to foster rent‐ seeking behavior. The existing literature on natural resources and corruption suffers from omitted variable bias. This paper re‐examines the effect of natural resource abundance on corruption using panel data estimation as well as new measures of resource endowments. I find evidence indicating that both oil extraction and mineral income is associated with more corruption. The adverse impact of oil on corruption is present both in democratic and nondemocratic countries. * Helpful comments from Ragnar Torvik, Jørgen Juel Andersen, Bjarne Strøm, Jon Hernes Fiva and participants at seminars at the Department of Economics, Norwegian University of Science and Technology, are gratefully acknowledged.

EVALUATION MODEL FOR SECURITY COMPONENTS: ACASE STUDY ON MALAYSIAN INTERNET BANKING

ABSTRACT. The usage of Internet Banking in Malaysia, which started about 10 years ago, has been well accepted by consumers. Statistics from Bank Negara Malaysia (BNM) show that every year there is an increase in the number of registered individual Internet banking users since its inception in Malaysia. As at the third quarter of 2010, there were approximately 9.2 million registered Internet Banking users compared to only 2.6 million in 2005. A survey of 264 CIMB Bank Berhad personnel revealed that although there is a high degree of confidence, with respondents claiming to be aware of requirements by the bank, further and thorough inspections suggest that there are several areas in which desirable knowledge and understanding are still lacking. Additionally, in order to identify the currents state of the security features offered, we performed an analysis of six (6) Internet Banking websites in Malaysia. Using the evaluation model proposed in this study, an analysis of Internet banking website security elements revealed that there is still room for improvement in areas such as helping users to execute transactions and create awareness on their responsibilities as outlined by the banks.
IMPROVED DIFFERENTIAL EVOLUTION STRATEGY FOR ANTENNA ARRAY PATTERN SYNTHESIS PROB- LEMS

An Improved Differential Evolution (IDE) algorithm is proposed for optimization problems. With the novel mutant operation adopting sub-optimal individual, the convergence of Differential Evolution (DE) algorithm is accelerated without increasing the risk of premature. Five typical test functions are minimized using DE and IDE algorithms, and the results show the superior performance of IDE algorithm. Furthermore, the algorithm is applied to pattern synthesis of two antenna arrays. Broad nulls are formed in radiation pattern of a linear array to suppress broad-band interferences. In a microstrip patch array, the sidelobe level of array is decreased about 12.9 dB and the mainlobe can scan to the desired angle.
Additions to the fauna of the Gashato Formation of Mongolia

In 1923 a small collection of fossil mammals was made from the Gashato Formation, which unconformably overlies the Djadokhta Formation near Shabarahk Usu in the Gurbun Saikhan Basin, north of the eastern end of the Altai Mountains. This collection was described in 1925.2 In that year a second, larger collection was made from these beds, including the remains of five new genera and six new species. The multituberculates have already been discussed,3 and preliminary descriptions of the remaining new forms are given in the present paper. A revised faunal list follows:
Multistable Rippling of Graphene on SiC: A Density Functional Theory Study

Graphene monolayer grown by Si evaporation from the 0001 surface of SiC displays a moire pattern of corrugation whose structure is ambiguous: different measurements and theoretical studies show either protruding bumps surrounded by valleys or, reversely, wells surrounded by crests. Here we address the fine structure of monolayer graphene on SiC by means of density functional theory, using a model including the full symmetry of the system and the substrate (1648 atoms) and therefore realistically reproducing the experimental sample. We find that the specific treatment of the vdW interactions between monolayer and the underlying substrate-bound buffer layer is crucial in stabilizing one or the opposite corrugation pattern, which explains the different results and measurement available in the literature. Our study indicates that at low temperature a state more closely following the topography of the underneath buffer layer is stabilized, while others are metastable. Because environmental conditions (e.g., te.
Advanced Wave-Equation Migration

Wave-equation migration methods can more accurately account for complex wave phenomena than ray-tracing-based Kirchhoff methods that are based on the high-frequency asymptotic approximation of waves. With steadily increasing speed of massively parallel computers, wave-equation migration methods are becoming more and more feasible and attractive for imaging complex 3D structures. We present an overview of several efficient and accurate wave-equation-based migration methods that we have recently developed. The methods are implemented in the frequency-space and frequency-wavenumber domains and hence they are called dual-domain methods. In the methods, we make use of different approximate solutions of the scalar-wave equation in heterogeneous media to recursively downward continue wavefields. The approximations used within each extrapolation interval include the Born, quasi-Born, and Rytov approximations. In one of our dual-domain methods, we use an optimized expansion of the square-root operator in the one-way wave equation to minimize the phase error for a given model. This leads to a globally optimized Fourier finite-difference method that is a hybrid split-step Fourier and finite-difference scheme. Migration examples demonstrate that our dual-domain migration methods provide more accurate images than those obtained using the split-step Fourier scheme. The Born-based, quasi-Born-based, and Rytov-based methods are suitable for imaging complex structures whose lateralmore » variations are moderate, such as the Marmousi model. For this model, the computational cost of the Born-based method is almost the same as the split-step Fourier scheme, while other methods takes approximately 15-50% more computational time. The globally optimized Fourier finite-difference method significantly improves the accuracy of the split-step Fourier method for imaging structures having strong lateral velocity variations, such as the SEG/EAGE salt model, at an approximately 30% greater computational cost than the split-step Fourier method. « less
Therapy for Childhood Acute Lymphoblastic Leukemia Anxiety , Depression , Stress , and Cortisol Levels in Mothers of Children Undergoing Maintenance

The purpose of this study was to compare anxiety, depression, and stress between mothers of children during maintenance treatment for acute lymphoblastic leukemia (ALL) and matched controls. Twenty-six mothers were recruited from the hematology unit at a children’s hospital, and 26 mothers were recruited from the community. Participants were matched to their child’s age and gender. Mothers completed the Hospital Anxiety and Depression Scale, the Perceived Stress Sale, and collected salivary cortisol 4 times a day for 3 consecutive days. Compared with mothers of healthy children, anxiety scores did not differ (P = .10), but depression scores were higher (P = .003) in mothers of children with ALL. More mothers in the ALL group scored above the cutoff of 7 indicating clinical anxiety (46%) and depressive symptoms (27%). A trend toward increased stress was found in mothers in the ALL group. No difference was found in overall daily cortisol (area under the curve), daily decrease in cortisol (slope), and cortisol awakening response. Mothers of children with ALL experienced emotional symptoms many months after the initial diagnosis.

Paleoceanography Sensitivity of the Greenland Ice Sheet to Interglacial Climate Forcing : MIS 5 e Versus MIS 11

The Greenland Ice Sheet (GrIS) is thought to have contributed substantially to high global sea levels during the interglacials of Marine Isotope Stage (MIS) 5e and 11. Geological evidence suggests that the mass loss of the GrIS was greater during the peak interglacial of MIS 11 than MIS 5e, despite a weaker boreal summer insolation. We address this conundrum by using the three-dimensional thermomechanical ice sheet model Glimmer forced by Community Climate System Model version 3 output for MIS 5e and MIS 11 interglacial time slices. Our results suggest a stronger sensitivity of the GrIS to MIS 11 climate forcing than to MIS 5e forcing. Besides stronger greenhouse gas radiative forcing, the greater MIS 11 GrIS mass loss relative to MIS 5e is attributed to a larger oceanic heat transport toward high latitudes by a stronger Atlantic meridional overturning circulation. The vigorous MIS 11 ocean overturning, in turn, is related to a stronger wind-driven salt transport from low to high latitudes promoting North Atlantic Deep Water formation. The orbital insolation forcing, which causes the ocean current anomalies, is discussed.
Polymorphism of CYP 2 D 6 , CYP 2 C 19 , CYP 2 C 9 and CYP 2 C 8 in the Faroese population

Objective: The purpose of the study was to study the distribution of poor and extensive metabolizers of CYP2C19 and CYP2D6 and to genotype for CYP2C8 and CYP2C9 among 312 randomly selected Faroese. Methods and Results: The participants were phenotyped for CYP2D6 with the use of sparteine. The distribution of the sparteine metabolic ratio (sparteine/didehydrosparteines) was bimodal, and 14.5% (n=44) (95% CI 10.7-18.9%) of the subjects were phenotyped as poor metabolizers. The frequency of poor metabolizers was higher (P=0.0002; χ2 test) among the Faroese than in other European populations (7.4%). Genotype analysis for the CYP2D6*3, *4, *6 and *9 alleles were performed using real-time PCR (TaqMan®), and we found 14.6% (n=45) (95% CI 10.8-19.0%) with deficient CYP2D6 genes (*3/*4, *4/*4, *4/*6, *6/*6) in the Faroese population. The subjects were phenotyped for CYP2C19 with the use of mephenytoin and 10 subjects, i.e. 3.2% (95% CI 1.6-5.9%) were phenotyped as poor metabolizers. Genotype analysis for the CYP2C19*2 and *3 alleles was performed by PCR analysis and 2.9% (n=9) (95% CI 1.3-5.4%) of the Faroese were found to have a deficient CYP2C19 gene all explained by the CYP2C19*2/*2 genotype. The allele frequencies of the CYP2C9*2 and CYP2C9*3 alleles were 8.8% (95% CI 6.7–11.4%) and 5.3% (95% CI 3.7–7.4%), respectively, while the CYP2C8*3 allele frequency was 6.9% (95% CI 5.0-9.2%). Real-time PCR (TaqMan®) was used for both CYP2C9 and CYP2C8 genotype analyses. Conclusion: The frequency of CYP2D6 poor metabolizers is two fold higher among the Faroese population compared to other Caucasians, while the frequencies of Faroese subjects with decreased CYP2C19, CYP2C8 and CYP2C9 enzyme activity are the same as seen in other Caucasian populations. A possible consequence might be a higher incidence of side effects among Faroese patients taking pharmaceuticals that are CYP2D6 substrates.
Synthesis and analysis for a novel single-stage isolated high power factor correction converter

A novel single-stage isolated high power factor correction (HPFC) converter operating in the discontinuous conduction mode is proposed in this paper. It is an integration of a buck-boost converter with a flyback converter by means of components placement and synchronous switching technology. It can achieve HPFC, tight output voltage regulation and lower voltage stress of the bulk capacitor, which is independent of the loads. The small-signal mathematical model for the proposed converter is derived separately by the averaging method and the current injected equivalent circuit approach. The IsSpice simulations and experimental results successfully verify the dynamics and performances of the proposed converter.
Factors affecting stock market performance with special reference to market-to-book ratio in banking - the Israeli case

One of the important factors affecting stock returns is the market-to-book ratio. In banking, the ratio has also been taken to be a proxy for the charter value of banks. The purpose of the paper is to derive and estimate empirically the factors that determine relative values of equity in banking. Our analytical framework is based on the discounted cash flow (DCF) approach of valuation. In our empirical test, we use data on Israeli banks. The main results are that risk, return and market and economic conditions have a significant effect on the ratio.
The Methodological Framework of Occupational Training in Culture and Art High Schools of Kazakhstan

The purpose of this study is to examine specific features of the traditional Kazakh dances as the methodological foundation of training specialists in the culture and art universities. The article describes the main typologies of Kazakh dances, such as ritual and ceremonial, combativehunting, work dances, household-imitative dances, festive and ceremonial dances, mass-thematic dances. National dance performs cultural, historical, aesthetic and semantic functions. Relevance of this problem is de rmined by the fact that i the present globalized world, national culture and traditions are oppressed by the multicultural environment; consequently, there is a need to train high-quality specialists in the field of cultural studies, who will be able to teach national culture. The authors used structural-functional, institutional and phenomenological approaches as well as methods of typological, historical, logical analysis. Research results show theoretical ways to address this problem. These include improvement of teaching and learning technologies, introduction of uniform terminological apparatus of the Kazakh dance, as well as various proven and advanced training technologies, in-depth study of the national dance, traditional culture, and heritage of the Kazakh dance art. This work can be used as a theoretical basis to develop the methodology of training future specialists in the field of cultural studies. 5262 A. K. KULBEKOVA ET AL.
Number 127 Prediction of the Rotor Aeromechanics in Descending Flight using Mixed Variational Geometrically Exact Beam Model and CFD Coupled Analysis

This paper presents prediction of the rotor aeromechanics for HART II experiment in a descending flight. The HART II was conducted to improve understanding of the Blade-Vortex Interaction (BVI) phenomena. For precise predictions of the aeromechanics of the HART II, CSD/CFD coupled analyses were conducted based on the delta load approach. In the CSD model, the mixed variational geometrically exact beam model was used to obtain the blade nonlinear behavior, and a CFD flow solver based on unstructured meshes was used for predicting the blade aerodynamic loads. The present beam model has advantages that displacements, internal forces/moments, and linear/angular momenta can be obtained directly. For the delta load approach, a finite-state dynamic inflow model was used to analyze trim condition for initial step in the present CSD model. The present results are compared with the measurement on the HART II rotor blades. The structural results show that the predicted flap deflection is quite similar with that of the measurement, but the torsional and lag deflections are under-predicted compared to those of the measurement.
