The effect of electric and chiral magnetic conductivities on azimuthally fluctuating electromagnetic fields and observables in isobar collisions

We study the space-time evolution of electromagnetic fields along with the azimuthal fluctuations of these fields and their correlation with the initial matter geometry specified by the participant plane in the presence of finite electric $\left(\sigma\right)$ and chiral magnetic $\left(\sigma_{\chi}\right)$ conductivities in Ru+Ru and Zr+Zr collisions at $\sqrt{s_{NN}}=200$ GeV. We observe the partially asymmetric behavior of the spatial distributions of the electric and magnetic fields in a conducting medium when compared to the Lienard-Wiechert (L-W) solutions, and deceleration of the decay of the fields is observed in both isobar collisions. While studying the correlation between the magnetic field direction and the participant plane, we see the sizeable suppression of the correlation in the presence of finite conductivities when compared to the L-W case, reflecting the importance of taking into account the medium properties such as conductivities while calculating the magnetic field induced observable quantities

SMEs BUSINESS GROWTH MODEL AND THE MEDIATING ROLE OF MARKET ORIENTATION

SMEs business growth is a central point for their success.Literature suggests different factors which inculcate smallerenterprises to grow but a tripod of three factors: reward system,decentralization of organization and owners’ attitude with amediating effect of market orientation have not been addressed.This study addresses the internal factors that contribute to the growthof SMEs with a mediating effect of market orientation. Data iscollected using survey method from Pakistani SMEs. The study arguesthat a significant potential lies in smaller enterprises to grow byadopting stated factors if firms are market oriente

ENTREPRENEURIAL MARKETING, ENVIRONMENTAL UNCERTAINTY AND PERFORMANCE OF FAMILY FIRMS

Businesses in general and family SMEs in specific are vulnerable to environmental uncertainty in underdeveloped countries. Stiff competitions, technological bursts and market turbulence appears as a catastrophe and a major cause for short life of many family SMEs. A few family SMEs still exist and survive in all these uncertain conditions. Various reasons been discussed in previous literature and had proved the importance of entrepreneurial marketing as one of the major sources of high performances. The marketing strategies opted by family SMEs having dimension of entrepreneurship, are not only self-beneficial but also the cause of new market trends. The primary purpose of this study is to consider the effect of opportunity vigilance, consumer centric innovation, value creation and risk management termed as entrepreneurial marketing and used as a fundamental approach for family SMEs to survive and grab high performances even under uncertain conditions. Results show that entrepreneurial marketing in family SMEs is positively associated with high performances even under uncertain environments. Previously uncertain environments were considered as one of the major cause for entrepreneurial marketing that does not qualify in our case. Family SMEs use entrepreneurial marketing as their vital tool for competitive markets to perform high irrespective of environmental conditions i.e. either favorable or unfavorable.Â

Energy scan/dependence of kinetic freeze-out scenarios of multi-strange and other identified particles in central nucleus-nucleus collisions

The transverse momentum (mass) spectra of the multi-strange and non-multi-strange (i.e. other identified) particles in central gold-gold (Au-Au), lead-lead (Pb-Pb), argon-muriate (Ar-KCl) and nickel-nickel (Ni-Ni) collisions over a wide energy range have been studied in this work. The experimental data measured by various collaborations have been analyzed. The blast-wave fit with Tsallis statistics is used to extract the kinetic freeze-out temperature and transverse flow velocity from the experimental data of transverse momentum (mass) spectra. The extracted parameters increase with the increase of collision energy and appear with the trend of saturation at the Beam Energy Scan (BES) energies at the Relativistic Heavy Ion Collider (RHIC). This saturation implies that the onset energy of phase transition of partial deconfinement is 7.7 GeV and that of whole deconfinement is 39 GeV. Furthermore, the energy scan/dependence of kinetic freeze-out scenarios are observed for the multi-strange and other identified particles, though the multiple freeze-out scenarios are also observed for various particles.Comment: 12 pages, 2 figures.

Correlation of Musculoskeletal Dysfunctions with Enhanced Computer Usage and Prescription of Management Strategies, In Computer Users of Afro Asian Institute, Lahore (Pakistan)

OBJECTIVE: To nail down the frequency of musculoskeletal problem’s in computer users and Recommend treatment/management options to the papulation with MSK problems. STUDY DESIGN: It is a cross-sectional descriptive study. PLACE AND DURATION: This study was performed from April 2019 to November 2019 at Afro Asian institute. Lahore (Pakistan). METHODOLOGY: One hundred subjects (54 males and 46 females) who were using computers were studied from Afro Asian institute Lahore. We used a questionnaire for collecting data about MSK status of individuals, data was statistically analyzed using SPSS. We used Chi-square test for evaluation of data. Moreover, Physiotherapy Management (Postural education, stretching of tightened structures, strengthening of weakened structures, heating modalities and periodic AROM exercises) and medical management (NSAIDS, muscle relaxant, analgesics) was prescribed for improvements, according to the severity and grading of MSK problems. RESULTS: The frequency of MSK dysfunctions was 52.60% in those who had been using computers for less than or equal to 2 hrs, 68.15% for 2-4 hrs computer users,81.45% for subjects with computer using of 4-6 hrs, and 93.72% in subjects who were using computer for more than 6 hours, respectively. The frequency of MSK problems (cervicalgia, LBP, shoulder pain, and elbow pain and pain in carpels) was classified according to a scale of pain ranging from grade I to grade V.

Volume Conduction Effects on Wavelet Cross-Bicoherence Analysis

Cross-bicoherence analysis is one of the important nonlinear signal processing tools which is used to measure quadratic phase coupling between frequencies of two different time series. It is frequently used in the diagnosis of various cognitive and neurological disorders in EEG (Electroencephalography) analysis. Volume conduction effects of various uncorrelated sources present in the brain can produce biased estimates into the estimated values of cross-bicoherence function. Previous studies have discussed volume conduction effects on coherence function which is used to measure linear relationship between EEG signals in terms of their phase and amplitude. However, volume conduction effect on crossbicoherence analysis which is quite a different technique has not been investigated up to now to the best of our knowledge. This study is divided into two major parts, the first part deals with the investigation of VCUS (Volume Conduction effects due to Uncorrelated Sources) characteristics on EEG-cross-bicoherence analysis. The simulated EEG data due to uncorrelated sources present in the brain was used in this part of study. The next part of study is based upon investigating the effects of VCUS on the statistical analysis of results of EEG-based cross-bicoherence analysis. The study provides an important clinical application because most of studies based on EEG cross-bicoherence analysis have avoided the issue of VCUS. The cross-bicoherence analysis was performed by detecting the change in MSCB (Magnitude Square CrossBicoherence Function) between EEG activities of change detection and no-change detection trials. The real EEG signals were use
