The Relationship between Fear of COVID-19 and Self-Medication and the Rate of Antibiotic Use in Patients Referred to COVID-19

Introduction The coronavirus pandemic can cause anxiety and stress among people, which can make them practice self-medication. This study aimed to investigate the relationship between fear of corona and self-medication and antibiotics use. Methods In a convenience sampling method, 250 people referring to COVID-19 centers including 16-hour comprehensive health services in Kermanshah, Iran, who tested positive and were not hospitalized were extracted from the SIB system. Data collection tools include three questionnaires including corona fear questionnaire, self-medication questionnaire, and self-medication by antibiotic questionnaire and an information form including demographic characteristics. Data were analyzed by SPSS version 25. Results The prevalence of self-medication was 59.6%. There was a significant correlation between self-medication and gender (P value <0.05) and education level (P value <0.05); the most common reason for self-medication was easy access to medicines through pharmacy drug stores. The mean score of fear of corona was higher in women and those who were not in a good financial position due to a lack of suitable economic status to see a doctor. Conclusion There was a direct and significant relationship between self-medication and self-medication by antibiotics. 59.6% of the participants used medicines themselves, buying over-the-counter in pharmacies. Also, there was a statistically significant difference between the mean score of corona fear in terms of not having a suitable economic status to see a doctor. This indicates that the lack of proper economic status among people with the coronavirus positive test to see a doctor increases the fear of the disease.
Post-traumatic Left Ventricular Apical Aneurysm With Endoluminal Thrombus

Here, we report a case of a 54-year-old man who presented with complications of a left ventricle apical aneurysm, which was the result of a myocardial infarction (MI). Interestingly, he sustained the MI following a cardiac contusion whilst playing rugby 32 years ago. He had another MI 10 years later, despite the presence of normal coronary angiography following the initial event, and presented with two episodes of sustained ventricular tachycardia over six months. The patient proceeded to surgical resection of the aneurysm and went on to make a good recovery.
Transmission of sound through sandwich panels

An analysis of the transmission of sound through sandwich panels (consisting of lightweight, flexible cores between relatively stiff skins) is presented here. First, previously given results for the free vibrations of such panels are analyzed and unified. Then, a traveling‐wave analysis is used to obtain impedances and transmission‐loss formulas, which are in turn compared with previously published experimental data. The comparison is relatively good, and confirmation of a symmetric coincidence effect is obtained. Further, the numerical results indicate that this symmetric coincidence generally occurs at a much lower frequency than does antisymmetric (shear wave) coincidence.
High Precision IGBT Health Evaluation Method: Extreme Learning Machine Optimized by Improved Krill Herd Algorithm

The insulated gate bipolar transformer (IGBT) is widely used in industry, aerospace, renewable energy and other fields, which requires high reliability. However, in the research field of IGBT health evaluation, there are still problems that the accuracy is not high enough and the reliability manager of IGBT cannot accurately grasp. In this study, an IGBT health status evaluation model based on improved krill herd optimized extreme learning machine (IKH-ELM) is proposed to accurately evaluate the health status of IGBT, provide guidance for timely replacement of components, thus reducing the failure probability and maintenance cost, and improving the system reliability. Firstly, the power cycle accelerated aging test, short pulse-high amplitude current test and thermal resistance measurement test are carried out to obtain the failure predictor parameters data of IGBT. Then, an IGBT health status classification method based on cloud model is proposed to make the health status assessment results more scientific. In addition, since the random selection of weights and thresholds of ELM affects the performance of the model, the krill herd algorithm is improved to optimize ELM for obtaining better prediction ability. Based on this, a prediction model based on IKH-ELM is established. Finally, the proposed model is proved to be more accurate and effective under the same experimental environment and the same index.
Network information flow: limits and achievability

An information theoretic upper bound on the information flow in discrete memoryless networks is found. The networks considered here can have multiple information sources and multiple sinks corresponding to each of the sources (which is also called as multicast). In the special case of networks with a single information source with multiple sinks, the bound coincides with the achievable region given by Ahlswede et al. (see IEEE Trans. on Inform. Theory, vol.46, no.4, p.1204-16, July 2000), and thus proves the optimality of the coding scheme proposed in it.
The Transition of the Hurricane Frederic Boundary-Layer Wind Field from the Open Gulf of Mexico to Landfall

Abstract Numerous aircraft, ship, buoy and land nation data were composited with respect to the center of Hurricane Frederic for two time periods: a 24 h period corresponding to the storm’s position in the open Gulf of Mexico on 12 September 1979, and an 8 h period corresponding to the landfall of Frederic near 0400 GMT on 13 September. Comparison of wind analyses for the two periods indicated a rotation of maximum inflow angles from the southeast to northeast quadrants and a strong frictional decrease of wind speed over land. Them and other features of the landfall analysis were compared with a model landfall study by Moss and Jones (1978). The landfall composite wind field was compared with the Fujita damage vector analysis to determine the damage time interval and mean wind speed range. Damage vector directions were found to be well correlated with the surface streamlines, with the most severe damage being associated with Frederic’s northern eyewall. Ten-meter-level wind speed data over water (VO) and .
The Background: from Observation to a `Non-Event' in Single-Crystal Diffractometry

The background–peak–background procedure is applied to calculate I and \sigma^2(I) from diffractometer data. A standard measurement produces a raw intensity R and a local background B. This standard operating procedure results in I = R − γB and \sigma^2(I) = \sigma^2(R) + \gamma^2\sigma^2(B), in which γ is the ratio of the times spent in measuring R and B. This approach has led to the conviction that the random error on I is determined by the signal and by the local background. Unfortunately, this concept is based on tradition. The strategic error in the background–peak–background routine is its complete neglect of the physical reality. Background intensities are produced by a single source, viz incoherent scattering. The relevant scattering processes are elastic (Rayleigh), inelastic (Compton) and pseudo-elastic (TDS) scattering. Their intensities are proportional to f^2, (Z-f^2/Z) and f^2[1-\exp(-2Bs^2)], which results in a background intensity fully defined by θ only. With observed backgrounds available, a background model has been constructed with its proper mix of the three scattering processes mentioned. This model is practically error free because it is based on a signal with size \sumB(H). The model-inferred background defines a zero level upon which the coherent Bragg intensities are superimposed. The distribution P(R) of the raw intensity is given by the joint probability P(I)P(B). P(R) is known via the observation R(H). The distribution P(B) is a counting statistical one, for which the mean and the variance are available through the background model. So P(I) = P(R)/P(B). This leads to I = R − b and \sigma^2(I) \approx I. If serious attention is paid to the observed background intensities, the latter – ironically enough – ceases to be an important element in the random error σ(I).
A pressure correction‐volume of fluid method for simulation of two‐phase flows

A pressure correction method coupled with the volume of fluid (VOF) method is developed to simulate two‐phase flows. A volume fraction function is introduced in the VOF method and is governed by an advection equation. A modified monotone upwind scheme for a conservation law (modified MUSCL) is used to solve the solution of the advection equation. To keep the initial sharpness of an interface, a slope modification scheme is introduced. The continuum surface tension (CST) model is used to calculate the surface tension force. Three schemes, central‐upwind, Parker–Youngs, and mixed schemes, are introduced to compute the interface normal vector and the gradient of the volume fraction function. Moreover, a height function technique is applied to compute the local curvature of the interface. Several basic test problems are performed to check the order of accuracy of the present numerical schemes for computing the interface normal vector and the gradient of the volume fraction function. Three physical problems, two‐dimensional broken dam problem, static drop, and spurious currents, and three‐dimensional rising bubble, are performed to demonstrate the efficiency and accuracy of the pressure correction method.

Teacher Evaluation for Growth and Accountability: Under What Conditions Does It Improve Student Outcomes?

Most teacher evaluation policies in the United States seek to improve student outcomes by providing developmental supports to grow teachers’ skills and by imposing accountability pressures to increase their effort. In this research synthesis and analytic essay, David D. Liebowitz argues that proper policy design has been understood as successfully balancing the accountability and growth dimensions of teacher evaluation. He details six conditions that determine whether joint-aim teacher evaluation policies will improve student outcomes and assesses the extent to which they are likely to be met given the causal evidence from the education, economics, social psychology, and management research literatures. The article concludes with recommendations to more clearly delineate the accountability and growth aims of teacher evaluation.
A study on daily dietary intake of adolescents in Aligarh District U.P.

Adolescents who have good nutritional status would grow to be healthy adults with high work efficiency and productivity. Nutritional status of adolescents is directly affected by their dietary intake and its pattern. Adolescent in present scenario have their own choices related to food. These choices are not governed by their nutritional requirements. Present study was conducted to assess the Daily Dietary Intake of Adolescents. Hence the researchers conducted a cross sectional survey to assess the dietary intake and pattern of adolescents studied in Vijay Vidhyalaya Inter College, Tochhigarh, Aligarh, Uttar Pradesh. 230 adolescents in the age group of 13 to 15 years were selected as samples using random sampling method. Equal consideration was given to both genders. Well-designed set of questionnaires was used to collect personal information of the students. Daily Dietary intake of students was assessed by using 24-hour dietary recall method and food frequency questionnaire. By using these retrospective methods of dietary survey dietary diversity scores obtained by researchers. The research study found a significant deficiency of approximately 48% in the food groups of fruits, vegetables. Protective Food Consumption is very much less in both genders of students. It was found that nearly 23.4% Adolescents skips breakfast, 13.91% skips their lunch and 3.48% skipped their dinner during the research study.
A variational subgrid scale model for transient incompressible flows

We introduce in this paper a variational subgrid scale model for the solution of the incompressible Navier–Stokes equations. With respect to classical multiscale-based stabilisation techniques, we retain the subgrid scale effects in the convective term and integrate the subgrid scale equation in time. The method is applied to the Navier–Stokes equations in an accelerating frame of reference and with Dirichlet (essential), Neumann (natural) and mixed boundary conditions. The concrete objective of the paper is to test a numerical algorithm for solving the non-linear subgrid scale equation and the introduction of the subgrid scale into the grid scale equation. The performance of the technique is demonstrated through the solution of two numerical examples: one to test the tracking of the subgrid scale in the convection term and the other to investigate the effects of considering the subgrid scale transient.
Structure of Plage Flux Tubes from the Inversion of Stokes Spectra. I. Spatially Averaged Stokes I and V Profiles

We present results of the inversion of spatially averaged Stokes I and V profiles emerging from plage regions near disk center. The observations analyzed in this work were recorded with the Advanced Stokes Polarimeter. All atmospheric quantities determining the radiative transfer in the thin flux-tube approximation are inferred self-consistently with the help of the inversion code described by Bellot Rubio et al. With regard to thermodynamics, the retrieved model atmospheres are found to behave as expected on theoretical grounds. For the first time, velocities inside and outside the tubes have been derived empirically. The magnetic atmospheres resulting from the inversion are characterized by the absence of significant motions in high layers but show strong velocity gradients in deeper layers. These gradients turn out to be essential for reproducing the whole shape of the observed profiles and, in particular, the asymmetries and the extended red tail of Stokes V. Our scenario predicts that the Stokes V zero-crossing wavelengths of Fe I and Fe II lines are redshifted by small but nonnegligible amounts, which is indeed confirmed by observations made with the Fourier Transform Spectrometer. According to recent numerical simulations, the internal downflows derived from the inversion could be produced by the strong shear that takes place in the intermediate layer between the magnetized interior and the ambient medium. Another possible origin is magnetic flux undergoing convective collapse within the resolution element.
LincRNA_XR209691.3 could promote Bombyx mori nucleopolyhedrovirus replication by interacting with BmHSP70

Long non‐coding RNAs (lncRNAs), a class of transcripts exceeding 200 nucleotides and lacking protein coding potential, have been proven to play important roles in viral infection and host immunity. Bombyx mori nucleopolyhedrovirus (BmNPV) is an important pathogen, which causes the silkworm disease and leads to a huge challenge to the sericultural industry. At present, research on the roles of insect lncRNAs in host‐virus interaction are relatively few. In this study, we explored the function of lincRNA_XR209691. 3 that was significantly up‐regulated in the silkworm fat body upon BmNPV infection. Firstly, the subcellular localization experiment confirmed that lincRNA_XR209691. 3 was present in both the nucleus and cytoplasm. Enhancing the expression of lincRNA_XR209691. 3 in BmN cells could promote the proliferation of BmNPV, while inhibition of lincRNA_XR209691. 3 by RNA interference suppresses the proliferation of BmNPV. Combining RNA pull‐down and mass spectrometry, we identified the host and BmNPV proteins that could interact with lincRNA_XR209691. 3. Next, by using truncation experiment and RNA immunoprecipitation (RIP) assay, it was found that lincRNA_XR209691. 3 could bind to the Actin domain of BmHSP70. Subsequently, overexpression of lncRNA_XR209691. 3 in BmN cells promoted the expression of BmHSP70, while knockdown of BmHsp70 suppressed the replication of BmNPV. Based on the above results, it is speculated that lincRNA_XR209691. 3 could promote the proliferation of BmNPV through interaction with BmHSP70, possibly by improving the stability of BmHSP70 and thereby enhancing the expression of BmHSP70. Our results shed light on the lncRNA function in insect‐pathogen interactions and provide a new clue to elucidate the molecular mechanism of BmNPV infection.
THE INFLUENCE OF SHARIA HOTEL INDICATORS TOWARDS ITS COMPETITIVE ADVANTAGE AND GUEST INTENTION TO STAY: AN APPRAISAL

Indonesia, the country with the largest Muslim population in the world, showed an increase in the development of sharia hotels that apply sharia’ laws and regulations as their operating system. This study aims to explore both hotel executives and consumers’ perceptions of sharia hotels and the impact on creating the hotel’s competitive advantage, which will affect guest intention to stay. In-depth interviews were completed with hotel executives of sharia and non-sharia hotels as one group and with sharia and non-sharia hotels guests as the other group. Two major themes were revealed from the interviews: governments are relatively slow in certifying standard regulations for Sharia hotels and there is still a discrepancy concerning the perceptions among hotel executives and customers about what constitutes a sharia hotel. A conceptual model is proposed showing factors that influence both the customers’ intention to stay at sharia hotels and their competitive advantage.
ANTIBACTERIAL, CYTOTOXICITY, AND BIOSYNTHETIC GENE CLUSTER ANALYSIS OF CORAL-ASSOCIATED ACTINOBACTERIA FROM MENJANGAN BESAR ISLAND, KARIMUNJAWA NATIONAL PARK

Coral-associated actinobacteria have been abundantly reported for their biological properties, particularly as antimicrobial and anticancer agents. This study was carried out to investigate the potential of coral-associated actinobacteria as antibacterial and cytotoxic agents and analyze the biosynthetic gene clusters (BGCs) of the most remarkable isolate. Coral Porites cylindrica was collected from Menjangan Besar Island, Karimunjawa National Park, Indonesia. Based on the antibacterial screening, three out of fifteen isolates demonstrated the potential as antibacterial agents, such as CSM 11, CSM 13, and CSM 18. They were identified as Streptomyces rochei, S. xiamenensis, and S. albus, respectively. There were no crude extracts that demonstrated antibacterial activity. S. rochei CSM 11 from A11 medium showed a strong cytotoxic activity with an IC50 value of 4.50 µg/mL. The antiSMASH analysis described that S. rochei contains 33 clusters with various bioactive compounds.
Weights of Feynman diagrams, link polynomials and Vassiliev knot invariants

We prove that the construction of Vassiliev invariants by expanding the link polynomials Pg,V(q, q−1) at the point q=1 is equivalent to the construction of Vassiliev invariants from Chern-Simons perturbation theory. In both constructions a simple Lie algebra g and an irreducible representation V of g should be specified. We give an example of a Vassiliev invariant of order six which cannot be obtained by these constructions if we restrict ourselves to simple Lie algebras and do not allow semisimple ones. The explicit description of primitive elements in the Kontsevich Hopf algebra is given.
Mechanical Characteristics and Bioactivity of Nanocomposite Hydroxyapatite/Collagen Coated Titanium for Bone Tissue Engineering

In the present study, we have analyzed the mechanical characteristics and bioactivity of titanium coating with hydroxyapatite/bovine collagen. Hydroxyapatite (HAp) was synthesized from a Pinctada maxima shell and has a stoichiometry (Ca/P) of 1.72 and a crystallinity of 92%, suitable for coating materials according to ISO and Food and Drug Administration (FDA) standards. Titanium (Ti) substrate coatings were fabricated at HAp concentrations of 1% (Ti/HAp-1) and 3% (Ti/HAp-3) and a bovine collagen concentration of 1% (Ti/HAp/Coll) by the electrophoresis deposition (EPD) method. The compressive strength of Ti/HAp-1 and Ti/HAp-3 was 87.28 and 86.19 MPa, respectively, and it increased significantly regarding the control/uncoated Ti (46.71 MPa). Furthermore, the Ti/HAp-coll (69.33 MPa) has lower compressive strength due to collagen substitution (1%). The bioactivity of Ti substrates after the immersion into simulated body fluids (SBF) for 3–10 days showed a high apatite growth (Ca2+ and PO43−), according to XRD, FTIR, and SEM-EDS results, significantly on the Ti/HAp-coll.
Safety and Immunogenicity of a ChAd155-Vectored Respiratory Syncytial Virus (RSV) Vaccine in Healthy RSV-Seropositive Children 12–23 Months of Age

Abstract Background Safe and effective respiratory syncytial virus (RSV) vaccines remain elusive. This was a phase I/II trial (NCT02927873) of ChAd155-RSV, an investigational chimpanzee adenovirus-RSV vaccine expressing 3 proteins (fusion, nucleoprotein, and M2-1), administered to 12–23-month-old RSV-seropositive children followed up for 2 years after vaccination. Methods Children were randomized to receive 2 doses of ChAd155-RSV or placebo (at a 1:1 ratio) (days 1 and 31). Doses escalated from 0.5 × 1010 (low dose [LD]) to 1.5 × 1010 (medium dose [MD]) to 5 × 1010 (high dose [HD]) viral particles after safety assessment. Study end points included anti–RSV-A neutralizing antibody (Nab) titers through year 1 and safety through year 2. Results Eighty-two participants were vaccinated, including 11, 14, and 18 in the RSV-LD, RSV-MD, and RSV-HD groups, respectively, and 39 in the placebo groups. Solicited adverse events were similar across groups, except for fever (more frequent with RSV-HD). Most fevers were mild (≤38.5°C). No vaccine-related serious adverse events or RSV-related hospitalizations were reported. There was a dose-dependent increase in RSV-A Nab titers in all groups after dose 1, without further increase after dose 2. RSV-A Nab titers remained higher than prevaccination levels at year 1. Conclusions Three ChAd155-RSV dosages were found to be well tolerated. A dose-dependent immune response was observed after dose 1, with no observed booster effect after dose 2. Further investigation of ChAd155-RSV in RSV-seronegative children is warranted. Clinical Trials Registration NCT02927873.
Growth hormone-Msp1 loci polymorphism and its association with first lactation traits in Sahiwal cattle

GH has important role in milk production and their polymorphisms may alter quality and quantity of gene's products and affects the phenotype. This study was designed to find the polymorphisms on GH-Msp1 loci and to find its association with milk production traits in Sahiwal cattle. Msp1 polymorphism of the bGH gene was identified in a population of Sahiwal cows. PCR-RFLP genotyping of 329 bp fragment of GH in exon 3 revealed three different allelic variants. The T allele was the major allele in Sahiwal cattle. The TT genotype Sahiwal cows yielded more FL305DMY, FLTMY and also had higher FLL than that of CT and CC genotypes cows. Results of the present findings reveal that TT allele of GH locus should be the favoured genotype in Sahiwal cattle breed and can be used in marker-assisted selection programmes.
Can a sperm selection technique improve embryo ploidy?

Spermatozoa with the highest motility retain a superior genomic integrity, and elevated sperm chromatin fragmentation (SCF) has been linked to a lower ability of the conceptus to develop and implant. Therefore, the utilization of a sperm selection method, such as microfluidic sperm selection (MFSS), is capable of reducing the SCF by yielding the most motile fraction of spermatozoa with the highest embryo developmental competence. What remains unclear, however, is the causal mechanism that links SCF to an impaired embryo development.
