Evaluation of Cellular miR-122 Expression in Association with the Presence of Varicella-Zoster Virus among Central Nervous System Tumors

Background: Brain tumors are all primary central nervous system (CNS) tumors with unclear etiologies and viral infections, especially human herpesviruses, which have emerged as a hot topic for comprehensive research. Objectives: The present study aimed at assessing the molecular epidemiology of varicella-zoster virus (VZV) and its association with microRNA 122 (miR-122) expression in CNS tumor samples. Methods: Fresh frozen tissue samples were collected from 60 CNS tumor patients and 45 healthy controls. A nested PCR assay was performed to detect the VZV-DNA. Subsequently, the expression level of miR-122 was evaluated in the CNS tumor tissue samples of patients and the brain tissue samples were obtained from healthy controls, using a real-time PCR assay. Results: Of 60 patients with CNS tumors, 29 were men and 31 were women. VZV-DNA was detected in 13.3% of the CNS tumor tissue specimens. There was no statistically significant association between the presence of VZV-DNA and different types of CNS tumors (P > 0.05). Furthermore, the expression level of miR-122 was significantly downregulated in the CNS tumor tissue samples obtained from the patients compared with those of the healthy controls (P < 0.05). Additionally, the expression level of miR-122 was significantly lower in the VZV-positive tumor samples as compared with those of the VZV-negative tumor samples and the healthy controls. Conclusions: Although VZV plays no direct role in the development of CNS tumors, the virus may affect the biology of CNS tumors by decreasing the expression levels of miR-122, which consequently leads to an increased risk of malignancy. However, the experimental data are not conclusive enough; so, further investigations are needed.
Applications of the Gauge-invariant uniqueness theorem for graph algebras

We give applications of the gauge-invariant uniqueness theorem, which states that the Cuntz-Krieger algebras of directed graphs are characterised by the existence of a canonical action of . We classify the C*-algebras of higher order graphs, identify the C*-algebras of cartesian product graphs with a certain fixed point algebra and investigate a relation called elementary shift equivalence on graphs and its effect on the associated graph C*-algebras.
Effectiveness and limitation of circle criterion for LTI robust control systems with control input nonlinearities of sector type

This paper considers linear time invariant systems with sector type nonlinearities and proposes regional ℒ︁2 performance analysis and synthesis methods based on the circle criterion. In particular, we consider the effect of non‐zero initial states and/or an ℒ︁2 disturbance inputs on the ℒ︁2 norm of a selected performance output. We show that both analysis and synthesis problems can be recast as linear matrix inequality (LMI) optimization problems, where, for synthesis, the outputs of the nonlinear elements are assumed available for control. Moreover, it is shown when the circle criterion does or does not help to improve the performance bound in robust control synthesis when compared with the existing linear analysis method.

Renormalization for the Harper equation for quadratic irrationals

In this paper, we use renormalization methods to study self-similarity in the fluctuations ηi of the Harper equation in the strong-coupling limit for quadratic irrationals of the form (a2+4−a)/2 for a∈N. Using the decimation method, we obtain a second-order functional recurrence which we prove rigorously has an entire fixed point. This fixed point governs the scaling of the fluctuations ηi in the strong-coupling limit.

This study was held in Fadhlia region, 22 km northeast of Mosul city, province center, and aims at knowing the effect of olive trees in soil optical properties, three sites of olive orchards were chosen with different ages and agricultural processes, the age of trees in first site is 200 years old, second site is 10 years old and third is 25 years old, three soil pedons were drilled under olive trees, and three others in uncultivated land, and several photographs for soil sites were taken using a digital camera to calculate RGB values, the color of the soil was then measured in field and laboratory using Munsell soil color charts, and use the Spectroradiometer in laboratory to draw the spectral reflectance curves of soil, the results obtained that RGB values were high in dry soils and decrease in moist state, and the percentage of spectral reflectance was lower than that of (47.3%) in the surface horizon soil of p5 under olive trees, hue, value and chroma were different between the layers of study sites in the field and laboratory for dry and moist state, and low values of the spectral reflectance were observed in surface horizons of most soil pedons at the wavelength (1750) nm .
Research on Middle-aged and Elderly Users’ Continuous Use Behavior of Online Leisure and Entertainment Platform

: This research aims to respond to the problem of declining user stickiness faced by online platforms providing information services for middle-aged and elderly, and promote the sustainable development of the business model of online leisure and entertainment platform. Based on social cognition theory and perceived value theory, the research constructs an analysis framework of the continuous use behavior of middle-aged and elderly users on online leisure and entertainment platform. It conducts an online questionnaire survey, and uses SPSS and AMOS to analyze and verify the 398 valid data from users. Good information quality and system quality of the platform can bring perceived benefit to middle-aged and elderly users and strengthen their continuous use behavior. However, the information quality of the platform and the perceived risk of users do not significantly affect their continuous use of the platform.
Flow and Reynolds number dependencies of one-dimensional vorticity fluctuations

Although significant attention has been given to the evolution of various characteristics of turbulent velocity and scalar fields with R λ, the Taylor microscale Reynolds number, there is a scarcity of data relating to the dependence of vorticity statistics on R λ. In this paper, we examine the dependence on R λ (= 27–1067) of the statistics of the spanwise (or lateral) vorticity component ω z , obtained in different types of flows. Measurements in grid turbulence, circular cylinder wakes and plane and square jets issued from different geometry nozzles were made using a 4-hot-wire vorticity probe. The vorticity variance, normalized by Kolmogorov scales, satisfies local isotropy closely and does not depend on R λ or the type of flow. Vorticity spectra in grid and wake flows agree with isotropic calculations and evolve with R λ at low wavenumbers. In wakes, the spectra do not change significantly even at low wavenumbers when R λ is greater than about 160. By contrast, the vorticity spectra in jets show a significant departure from local isotropy at low wavenumbers, irrespectively of R λ. The pdf of the vorticity fluctuation exhibits good symmetry with single exponential tails for R λ < 160, independently of the flow. The tails stretch out to larger amplitudes and have a double exponential structure at largerR λ. Although the pdf depends on R λ, its dependence on the flow is small.
Self-assembled InAs quantum dots on patterned GaAs(001) substrates: Formation and shape evolution

We report on the formation of ordered and size homogeneous InAs quantum dot (QD) arrays on patterned GaAs(001) substrates. A material depletion region is observed around the patterned area while a long-range homogeneous distribution of QDs is found inside the patterned area. A sample with less InAs deposition shows a gradient in the material distribution over the patterned area. Based on these observations we propose a simple model to describe the QD formation in the patterned area. The QD shape evolution is also investigated and discussed.
Circadian rest-activity rhythm and longitudinal brain changes underlying late-life cognitive decline

The neurobiological substrates underlying the relationship of circadian rest‐activity rhythm (RAR) alteration with accelerated late‐life cognitive decline are not clearly understood. In the present study, the longitudinal relationship of objectively measured circadian RAR with in vivo Alzheimer disease (AD) pathologies and cerebrovascular injury was investigated in older adults without dementia.
Statistical Analysis of Weighted Networks

The purpose of this paper is to assess the statistical characterization of weighted networks in terms of the generalization of the relevant parameters, namely, average path length, degree distribution, and clustering coefficient. Although the degree distribution and the average path length admit straightforward generalizations, for the clustering coefficient several different definitions have been proposed in the literature. We examined the different definitions and identified the similarities and differences between them. In order to elucidate the significance of different definitions of the weighted clustering coefficient, we studied their dependence on the weights of the connections. For this purpose, we introduce the relative perturbation norm of the weights as an index to assess the weight distribution. This study revealed new interesting statistical regularities in terms of the relative perturbation norm useful for the statistical characterization of weighted graphs.
Construction of organizational culture for ideal performance of Islamic-based junior high schools in Indonesia

The deficiency of Islamic-based schools (called as Pesantren in Indonesia) in science requires adjustment. In this sector, Indonesian government is present through the implementation of the Islamic-based boarding Junior High Schools (henceforth SMP-BP) program, which was established by the Ministry of Education and Culture to equip students with intellectual, moral, and spiritual balances. However, there is still a need for constructing a framework of organizational culture to enhance the efficacy of the program. Hence, the present study delves into a framework of organizational culture for ideal performance of and the efficacy of education process in Pesantren. This study was based in two SMP-BPs in Aceh, a province of Indonesia (e.g. Al Mujaddid and Darul Amin), and was conducted by following the procedure of descriptive research under qualitative design. The required data were gathered using interviews from a total of 12 informants consisting of school principal, coordinator of the program, and teachers. The data were further analyzed by following Miles and Huberman’s stages of qualitative data analysis comprising coding, presentation, and conclusion drawing. The results revealed that the construction of organizational culture for an ideal performance of Pesantren in Indonesia encompassed four key dimensions, i.e. (1) establishing organizational behavior standards, (2) increasing the stability of organization’s social system, (3) revitalizing school management, and (4) developing human resources. This study contributes to equipping Pesantren stakeholders with awareness and willingness to improve the efficacy of Islamic-based school performance in Indonesia. Future research is directed to efforts of fostering dynamic organization culture and school management both cultural and philosophical education.
Anisotropic proton emission after fragmentation of H2O by multiply charged ions

Ion-induced fragmentation of H2O molecules was investigated experimentally by 3He2+ impact as a function of the energy in the range from 1 to 5 keV, as well as a function of the charge state of 20 keV 20Neq+ projectiles (q = 3 and 7). The fragments were detected in the angular range from 25° to 135° with respect to the incident beam direction. Particular emphasis is given to protons originating from collisions at large impact parameters involving a Coulomb explosion mechanism. Absolute cross sections dσ/dΩ, differential in the emission angle, are found to be anisotropic. Protons are preferentially emitted at angles near 90°, with cross sections being ∼50% larger than those at forward and backward angles. Possible mechanisms causing anisotropic emission of protons from fragmenting H2O are discussed.
Taming Big Data

Social media websites such as Facebook and Twitter provide an unprecedented amount of qualitative data about organizations and collective behavior. Yet these new data sources lack critical information about the broader social context of collective behavior—or protect it behind strict privacy barriers. In this article, I introduce social media survey apps (SMSAs) that adjoin computational social science methods with conventional survey techniques in order to enable more comprehensive analysis of collective behavior online. SMSAs (1) request large amounts of public and non-public data from organizations that maintain social media pages, (2) survey these organizations to collect additional data of interest to a researcher, and (3) return the results of a scholarly analysis back to these organizations as incentive for them to participate in social science research. SMSAs thus provide a highly efficient, cost-effective, and secure method for extracting detailed data from very large samples of organizations that use social media sites. This article describes how to design and implement SMSAs and discusses an application of this new method to study how nonprofit organizations attract public attention to their cause on Facebook. I conclude by evaluating the quality of the sample derived from this application of SMSAs and discussing the potential of this new method to study non-organizational populations on social media sites as well.
Tax Cuts, Firm Growth, and Worker Earnings: Evidence from Small Businesses in Canada

This paper assesses the effects of corporate tax reductions for small businesses on their growth and employee earnings. Following a 2014 reform in Quebec, firms that received tax cuts increase their employment, payrolls, and capital stock by 1.8 percent, 2.4 percent, and 4.4 percent, respectively, relative to unaffected firms. In turn, these firms experience 5.2 percent, 0.4 percentage points, and 891 dollars increases in their sales, profit margins, and EBITDA per worker. Furthermore, annual earnings increase by 1.3 percent for workers in treated firms relative to workers in control firms. Additionally, the effects are larger for firms and workers in high-technology industries, although we do not find different responses based on labor market concentrations. Taken together, these findings suggest that tax incentives specifically designed for small businesses may lead to significant increases in their growth and worker earnings, and targeting a specific sector or industry when designing corporate tax cuts may be an effective way to stimulate growth and employment in the economy.

Comparison between a 1D and a 2D numerical model of an active magnetic regenerative refrigerator

The active magnetic regenerator (AMR) refrigeration system represents an environmentally attractive alternative to vapour-compression refrigeration. This paper compares the results of two numerical AMR models: (1) a 1D finite difference model and (2) a 2D finite element model. Both models simulate a reciprocating AMR and can determine the cyclical steady-state temperature profile of the system as well as performance parameters such as the refrigeration capacity, the work input and the coefficient of performance (COP). The models are used to analyse an AMR with a regenerator made of flat parallel plates of gadolinium operating in the presence of a 1 T magnetic field. The results are used to discuss under which circumstances a 1D model is insufficient and a 2D model is necessary. The results indicate that when the temperature gradients in the AMR perpendicular to the flow are small a 1D model obtains accurate results of overall results such as the refrigeration capacity but that a 2D model is required for a detailed analysis of the phenomena occurring inside the AMR.
Statistical Inference for Coefficient Alpha

Rigorous comparison of the reliability coefficients of several tests or measurement procedures requires a sampling theory for the coefficients. This paper sum marizes the important aspects of the sampling theory for Cronbach's (1951) coefficient alpha, a widely used internal consistency coefficient. This theory enables researchers to test a specific numerical hypothesis about the population alpha and to obtain confidence intervals for the population coefficient. It also permits researchers to test the hypothesis of equality among several coefficients, either under the condition of inde pendent samples or when the same sample has been used for all measurements. The procedures are illus trated numerically, and the assumptions and deriva tions underlying the theory are discussed.
The Influence of Short Video News on College Students’ Emotional Interaction—— A Comparative Experiment Based on Gender Differences

: The purpose of this study is to explore the interaction of college students’ emotional states when they receive short video news pieces with different emotions. At the same time, it analyzes whether there will be differences in modality changes and obviousness of the topic between different genders. This study used a controlled experiment with a stratified sampling method to select 118 students from Hunan University of Science and Technology. The results show that when college students are exposed to news topics with positive or negative attributes, their original emotional state will affect their subsequent emotional response. This pattern of interaction reflects the psychological theory of excitation transfer. In addition, the positive framing of short video news has a significant impact on positive audience sentiment and increased trust in the media. Female representatives had more significant emotional interactions. However, the prominence of news topics is not directly related to the emotional changes of college students.
CEO Trustworthiness: Its Antecedents and Effects on Corporate Governance

We develop an integrated set of propositions describing the relationships among CEO characteristics, the perceived trustworthiness of the CEO, and the board of directors’ decisions concerning the governance structure of the firm. In particular, we propose that CEO education, tenure, experience, board memberships and founder status affect the board’s perception of the CEO’s ability, benevolence, and integrity (the three key trustworthiness dimensions), and that these trustworthiness perceptions then affect the board’s choice of governance mechanisms with regard to CEO compensation mix, CEO/board chair duality, board size, and outsider representation on the board. Our theoretical development suggests that agency theory’s difficulties in explaining corporate governance may be the result of researchers’ failure to incorporate CEO trustworthiness into their models.
Analysis of General Circulation Model Sea-Surface Temperature Anomaly Simulations Using a Linear Model. Part I: Forced Solutions

Abstract Experiments are presented which indicate that many features of the response of a general circulation model to sea-surface temperature anomalies in the equatorial Pacific east of the dateline can be reproduced with a linear nondivergent barotropic vorticity-conserving model. The midlatitude response to anomalous forcing is especially well reproduced by the simple model if it is linearized about the general circulation model’s wavy control climatology. Diagnosis of the linear solutions using kinetic energy and enstrophy budget, as well as indicators of group velocity, indicates that basic state–perturbation interaction supplies nearly as much energy to the perturbation flow as anomalous forcing does. Further experiments show that the linear model is incapable of reproducing the finding of Geisler et al. that the structure of the general circulation model's midlatitude response is insensitive to the longitudinal position of the forcing anomaly. However, a Green’s function analysis of the linear mode.
Buoyancy-Driven Heat Transfer in Nanofluid-Filled Trapezoidal Enclosure with Variable Thermal Conductivity and Viscosity

Heat transfer performance utilizing nanofluids in a trapezoidal enclosure is investigated taking into account variable thermal conductivity and viscosity. Transport equations are modelled by a stream-vorticity formulation, and are solved numerically by the finite difference method. The effects of the Rayleigh number, base angle, volume fraction, and size of nanoparticles on flow and temperature patterns as well as the heat transfer rate are presented. We found that the effect of the viscosity was more dominant than the thermal conductivity, and there is almost no improvement in heat transfer performance utilizing nanofluids.
