Web-Based Reporting of Post-Vaccination Symptoms for Inactivated COVID-19 Vaccines in Jordan: A Cross-Sectional Study

Background: The perception of COVID-19 vaccines as being unsafe is a major barrier to receiving the vaccine. Providing the public with accurate data regarding the vaccines would reduce vaccine hesitancy. Methods: A cross-sectional study was conducted to collect data on the side effects experienced by the vaccinated population to assess the safety of the inactivated COVID-19 vaccine. Results: The majority of the study participants (n = 386) were female (71.9%), and 38.6% of them were under 30 years old. Around half of the participants (52.8%) reported side effects after receiving the inactivated COVID-19 vaccine. Fatigue (85.1%), a sore arm at the site of the injection (82.1%), and discomfort (67.2%) were the most commonly reported side effects after the first dose. Reporting side effects was significantly associated with the female sex (p-value = 0.027). Significant associations between being female and experiencing chills, muscle or joint pain, anorexia, drowsiness, and hair loss were also found, as well as being above the age of 30 and experiencing a cough. Being a smoker was significantly associated with experiencing a cough, and a headache. Furthermore, chills, and a sore throat were significantly associated with individuals who had not been infected before. Conclusion: Mild side effects were reported after receiving the inactivated COVID-19 vaccine. Fatigue was the most commonly reported side effect. Females, older adults, smokers, and those who had never been infected with COVID-19 had a greater susceptibility to certain side effects.
Phase transitions of a multicomponent Widom‐Rowlinson model

We study a multicomponent version of the ``A−B'' model of Widom and Rowlinson, generalized in a symmetric way: There is an infinite repulsive interaction between any two unlike particles. We consider both lattice and continuum versions of the model and show that the ``demixing'' transition occurs for any finite number M of components, all having the same activity. No conclusion can be drawn about this transition in the limit M→∞. It is shown, however, that another transition, in which the density is greater on one of the sublattices, appears at a finite value of M which persists for all larger M at any fixed value of the activity. In the limit M→∞, z→0, M z=ζ, const, this system apparently becomes ``equivalent'' to a one‐component system with activity ζ in which there is an exclusion for occupancy of nearest neighbor sites. The latter transition then becomes the ``hard square'' transition.
The evolution of the magnetic structures in electron phase-space holes: Two-dimensional particle-in-cell simulations

Observations have shown that electron phase-space holes (electron holes) possess regular magnetic structures. In this paper, two-dimensional (2D) electromagnetic particle-in-cell (PIC) simulations are performed in the (x, y) plane to study magnetic structures associated with electron holes under different plasma conditions. In the simulations, the background magnetic field (B(0) = B(0)(e(x)) over right arrow) is along the x direction. The combined actions between the transverse instability and stabilization by the background magnetic field lead to the generation of the electric field E(y). Then electrons suffer the electric field drift and produce the current in the z direction, which leads to the fluctuating magnetic field along the x and y directions. Meanwhile, the motion of the electron holes along the x direction and the existence of the electric field E(y) generate the fluctuating magnetic field along the z direction. In very weakly magnetized plasma (Omega(e) omega(pe)), electrostatic whistler waves with streaked structures of E(y) are excited. The fluctuating magnetic field delta B(x) and delta B(z) also have streaked structures. The relevance between our simulation results and the magnetic structures associated with electron holes observed in the plasma sheet is also discussed.
Mg coordination in a MgSiO 3 glass using neutron diffraction coupled with isotopic substitution

Neutron diffraction with isotopic substitution ($^{25}\mathrm{Mg}$/${}^{\mathrm{nat}}$Mg) is used to investigate the Mg environment in MgSiO${}_{3}$ glass. The neutron-diffraction data are coupled with x-ray diffraction and a reverse Monte Carlo modeling. The Mg environment can be fully resolved from other contributions. We show that two Mg-O contributions are present at \ensuremath{\sim}1.99 \ifmmode\pm\else\textpm\fi{} 0.01 \AA{} and 2.21 \ifmmode\pm\else\textpm\fi{} 0.01 \AA{}, with an average coordination number of 4.5 \ifmmode\pm\else\textpm\fi{} 0.1 O neighbors around Mg. These distorted Mg sites participate in an inhomogeneous distribution of Mg atoms. This organization results from the liquid state and has implications in understanding the immiscibility gap and glass forming ability.
Absolute-Pitch Judgments of Black and White-Key Pitches

Absolute-pitch possessors have been reported to identify black-key pitches less quickly and accurately than they identify white-key pitches. However, it is possible in these experiments that the greater speed of identifying white-compared with black-key pitches was due to a motor response bias because the motor requirements for indicating a black-key pitch were more difficult than those for indicating a white-key pitch. The greater accuracy in identifying white-compared with black-key pitches may have been due to a choice response bias favoring white-key pitch responses. We compared absolute- pitch judgments of black-and white-key pitches in a task free of motor response biases. Subjects compared the pitch of an auditory tone with a visually presented pitch name and responded Same or Different. The absolute- pitch possessors responded significantly more slowly to black- key auditory pitches, and to black- key visual pitch names, than to white-key pitches and pitch names. These differences may have been due to perceptual and retrieval processes associated with the frequencies with which black-and white-key pitches and pitch names occur in music literature. Another possible explanation is that absolute-pitch possessors may learn absolute pitch for only white-key pitches in development and may interpolate blackkey pitches from neighboring white-key pitches. Experiments to test these alternative accounts are proposed.
The Use of Random Forest Regression for Estimating Leaf Nitrogen Content of Oil Palm Based on Sentinel 1-A Imagery

For obtaining a spatial map of the distribution of nitrogen nutrients from oil palm plantations, a quite complex Leaf Sampling Unit (LSU) is required. In addition, sample analysis in the laboratory is time consuming and quite expensive, especially for large plantation areas. Monitoring the nutrition of oil palm plants can be achieved using remote-sensing technology. The main obstacles of using passive sensors in multispectral imagery are cloud cover and shadow noise. This research used C-SAR Sentinel equipped with active sensors that can overcome cloud barriers. A model to estimate leaf nitrogen nutrient status was constructed using random forest regression (RFR) based on multiple polarization (VV-VH) and local incidence angle (LIA) data on Sentinel-1A imagery. A sample of 1116 LSU data from different islands (i.e., Sumatra, Java, and Kalimantan) was used to develop the proposed estimation model. The performance evaluation of the model obtained the averaged MAPE, correctness, and MSE of 9.68%, 90.32% and 11.03%, respectively. Spatial maps of the distribution of nitrogen values in certain oil palm areas can be produced and visualized on the web so that they can be accessed easily and quickly for various purposes of oil palm management such as fertilization planning, recommendations, and monitoring.
Delay model of circadian gene expression with two negative feedback loops

Abstract In this theoretical paper we propose a quantitative minimal model for circadian gene expression based on two negative feedback loops. We perform numerical simulations to analyse its dynamics and parameter sensitivities in free-running conditions, and verify the entrainability by a single periodic driver. We furthermore apply two simultaneously acting external drivers, leading to aperiodic oscillations in the case of a single-loop system. These can be turned into regular periodic oscillations by introduction of a second loop. Our studies confirm the increasing evidence that multiple feedback loops increase the robustness of regulatory systems, and stress the particular situation of systems that are close to transition from free-running oscillation to steady-state behaviour. We discuss possible molecular realisations of the featured feedback loops and suggest the application of complex patterns of external stimulation as a generally useful approach to assess the functionality of models of circadian systems.
Anxiety, depression and post-traumatic stress disorder and related factors among Chinese population during the COVID-19 pandemic: A cross-sectional study

The sudden outbreak of coronavirus disease 2019 (COVID-19) has deep and wide negative mental impacts on the public, and studies on the impact of COVID-19 on social and mental well-being are necessary. This study aimed to evaluate mental distress, including anxiety, depression, and post-traumatic stress disorder (PTSD), and its related risk factors in Chinese adults in the early stages of the COVID-19 pandemic. This study used a large-scale cross-sectional design. A total of 2067 adult participants completed the online survey via REDcap from 1st to 15th of March 2020 during the COVID-19 outbreak in China. Anxiety, depression, PTSD, and related risk factors, including self-efficacy, coping style, and social support, were measured using valid and reliable instruments. The data were analyzed using multiple linear regression. We found that 201 (9.7%) participants reported moderate-to-severe anxiety, 669 (33.8%) reported depression, and 368 (17.8%) reported symptoms of PTSD. Self-efficacy, coping style, and social support significantly affected anxiety, depression, and PTSD symptoms. Participants’ sociodemographic characteristics, COVID-19 pandemic-related factors, low self-efficacy, low social support, and negative coping were predictors of mental distress during the COVID-19 pandemic. Our study will help healthcare professionals carry out early predictions and identification of high-risk groups and provide appropriate interventions to target groups during public health emergencies that plague the world.
Relationship of Balloon Size in Pulmonary Valvuloplasty Outcome

Objective: To evaluate the relation between balloon size and outcome of patients undergoing pulmonary valvuloplasty. Study Design: A quasi-experimental study. Place and Duration: Pediatric Cardiology Department of Chaudhary Pervaiz Elahi Institute of Cardiology, Multan, Pakistan from January 2021 to June 2022. Methodology: Children of both genders aged less than 15 years having severe pulmonary stenosis and who underwent pulmonary valvuloplasty during the study period were analyzed. After 24 hours post procedure, echocardiography was done to see echo gradient across pulmonary valve, tricuspid regurgitation, pulmonary regurgitation, right ventricular dysfunction or pericardial effusion. Procedure was considered successful if the residual gradient across pulmonary valve was < 40 mmHg, pulmonary regurgitation < moderate and patients had no major complications. Results: In a total of 75 children, 42 (56.3%) were male. The mean age was 6.24 ± 4.81 years. Cyanosis was observed in 10 (13.3%) children while there was right ventricular dysfunction in 6 (8.0%) children. The pulmonary valvuloplasty procedure was successful in 53 (70.6%) cases while in remaining 22 (29.4%) cases, the procedure was partially successful because of infundibular obstruction. We observed that the degree of pulmonary regurgitation was greater when annulus- balloon ratio was 1.3 or more than that (p<0.0001). Practical Implications: Large balloons do not impart advantages beyond that produced by balloons between 1.2-1.4 times of the annular size but further research is required to ascertain these findings Conclusion: Signification relation exists regarding balloon size and outcome of children undergoing pulmonary valvuloplasty as the degree of pulmonary regurgitation was greater when annulus- balloon ratio was 1.3 or more. Keywords: Cyanosis, pulmonary regurgitation, pulmonary valvuloplasty, right ventricular dysfunction.
Multi-attribute classification using fuzzy integral

Fuzzy set theory can provide a suitable framework for pattern classification, because of the inherent fuzziness involved in the definition of a class or a cluster. Fuzzy set theory is discussed based on a fuzzy pattern matching procedure, where partial matching values with respect to a given attribute are combined. This approach is closely related to a statistical approach to pattern classification. A new method based on a fuzzy integral and possibility theory is presented. A critical examination of the statistical approach and the supervised learning process is outlined. Experimental test results on real data are presented. <<ETX>>
Formulas for stationary planar fibre processes I - general theory

In the paper fibre processes are considered, i.e. discrete sets of curves distributed at random in the plane. For translation invariant fibre processes the PALM distribution of the angle in a typical fibre point is defined, and point processes are studied which are obtained by intersection with lines. As a special case motion invariant, i.e. translation invariant and isotropic, fibre processes are treated. Finally weighted fibre processes are considered. As example segment processes are investigated.

Is Vaccine Hesitancy Affected by Distrust in the Healthcare System? A Study in Turkish Population

ABSTRACT The aim of this study is to examine the effect of the perception of distrust in the healthcare system on vaccine hesitancy and to determine the association between the sociodemographic characters of the participants and their perception of distrust and their vaccine hesitancy. The population consisted of individuals who were 20 years old and above and were residing in Turkey. A total of 986 people participated in the study. The data were collected through a questionnaire that was prepared on Google Forms. As a result of the regression analysis, distrust in the healthcare system explained 20.7% of total variance in vaccine hesitancy and an increase in the perception of distrust in the healthcare system statistically increased the vaccine hesitancy. In the study, it was also determined that the participants’ perceptions of distrust in the healthcare system caused statistically significant differences based on the variables of marital status, employment status, alcohol consumption, age, education level and income level. It was revealed that the participants’ perceptions of vaccine hesitancy caused a statistically significant difference only based on age and the frequency of applying to the health institution.
Clustering of H I galaxies in the H I Parkes All Sky Survey and Arecibo Legacy Fast ALFA Survey

We investigate the clustering of H I-selected galaxies in the Arecibo Legacy Fast ALFA Survey (ALFALFA) and compare results with those obtained for the H I Parkes All Sky Survey (HIPASS). Measurements of the angular correlation function and the inferred 3D clustering are compared with results from direct spatial-correlation measurements. We are able to measure clustering on smaller angular scales and for galaxies with lower H I masses than was previously possible. We calculate the expected clustering of dark matter using the redshift distributions of the HIPASS and ALFALFA, and show that the ALFALFA sample is somewhat more antibiased with respect to dark matter than the HIPASS sample.
Collisions Transfer Coherence

Ultrafast photoexcitation of molecules prepares coherent superpositions of vibrational states, forming wave packets. We show direct experimental evidence that impulsive collisions of photo-fragments with large energy lossgenerate new coherent superpositions of vibrational states, causing coherence among previously unoccupied states. We demonstrate the effect in the model system of I 2 molecules in Kr solids. This coherence transfer-even in the presence of very strong dissipation-may be used for control strategies in condensed-phase photoreactions.
Anti-Obesity Effects of Isorhamnetin and Isorhamnetin Conjugates

Isorhamnetin is a plant-derived secondary metabolite which belongs to the family of flavonoids. This review summarises the main outcomes described in the literature to date, regarding the effects of isorhamnetin on obesity from in vitro and in vivo studies. The studies carried out in pre-adipocytes show that isorhamnetin is able to reduce adipogenesis at 10 μM or higher doses and that these effects are mediated by Pparγ and by Wnt signalling pathway. Very few studies addressed in rodents are available so far. It seems that treatment periods longer than two weeks are needed by isorhamnetin and its glycosides to be effective as anti-obesity agents. Nevertheless, improvements in glycaemic control can be observed even in short treatments. Regarding the underlying mechanisms of action, although some contradictory results have been found, reductions in de novo lipogenesis and fatty acid uptake could be proposed. Further research is needed to increase the scientific evidence referring to this topic; studies in animal models are essential, as well as randomised clinical trials to determine whether the positive results observed in animals could also be found in humans, in order to determine if isorhamnetin and its glycosides can represent a real tool against obesity.
On van der Waals friction: I. Between two atoms

Neglecting retardation and all other relativistic effects, we find the van der Waals force between two identical atoms mimicked as harmonic oscillators, constrained to move with constant relative velocity on fixed parallel tracks, starting infinitely far apart at time t=−∞, each in its ground state. The component parallel to the motion has an irreversible part, producing finite excitation probabilities as t→+∞. In this sense, the calculation demonstrates that the atoms are subject to nonzero frictional resistance, with the immediate implication that friction is experienced also by an atom moving outside and parallel to the surface of an electrically dilute and nonabsorptive half-space. The next paper in this series finds the friction experienced by an atom outside a half-space which may be absorptive and electrically dense.
Efficacy of Prohexadione calcium and Paclobutrazol on Storage Life of Clapp’s Favorite Pear

Present investigation was carried out to study the efficacy of growth retardants viz., prohexadione calcium and paclobutrazol on storage life of pear cv. ‘Clapp’s Favourite’ during the year 2015-2016. The experiment was laid out with thirteen treatments replicated thrice on 12-year-old-pear tree with uniform vigor and health under uniform cultural practices. The treatment comprises of single and double spray of growth retardants, i.e., prohexadione calcium (100 ppm, 200 ppm and 300 ppm) and paclobutrazol (100 ppm, 200 ppm and 300 ppm). The orchard soil was moderately deep with good fertility status. Data was recorded on storage life of the pear at (7, 14, 21 and 28) day’s interval and results revealed that both the growth retardants prohexadione calcium and paclobutrazol had showed a significant influence on total sugars, TSS, acidity and physiological loss in weight. After 28 days of storage minimum physiological loss in weight (14.17 %) and acidity (0.20 %) was recorded with the application of prohexadione calcium @ 200 ppm sprayed twice closely followed by prohexadione calcium @ 200 ppm sprayed twice. Application of prohexadione calcium @ 200 ppm and paclobutrazol @ 200 ppm had also showed a significant influence on TSS (15.31 % and 15.17 %, respectively) and total sugars (13.48 % and 13.40 %). Minimum values for all the characters were observed in control. Results revealed that application of prohexadione calcium @ 200 ppm and 300 ppm sprayed twice will enhance the shelf life of Clapp’s Favourite pear.
Numerical investigation of turbulent channel flow

Fully developed turbulent channel flow has been simulated numerically at Reynolds number 13800, based on centre-line velocity and channel half-width. The large-scale flow field has been obtained by directly integrating the filtered, three-dimensional, time-dependent Navier-Stokes equations. The small-scale field motions were simulated through an eddy-viscosity model. The calculations were carried out on the ILLIACIV computer with up to 516096 grid points. The computed flow field was used to study the statistical properties of the flow as well as its time-dependent features. The agreement of the computed mean-velocity profile, turbulence statistics, and detailed flow structures with experimental data is good. The resolvable portion of the statistical correlations appearing in the Reynolds-stress equations are calculated. Particular attention is given to the examination of the flow structure in the vicinity of the wall.
Morphometric Changes of Osteocyte Lacunar in Diabetic Pig Mandibular Cancellous Bone

Osteocytes play an important role in bone metabolism. The interactions of osteocytes with the surrounding microenvironment can alter cellular and lacunar morphological changes. However, objective quantification of osteocyte lacunae is challenging due to their deep location in the bone matrix. This project established a novel method for the analytical study of osteocytes/lacunae, which was then used to evaluate the osteocyte morphological changes in diabetic pig mandibular bone. Eight miniature pigs were sourced, and diabetes was randomly induced in four animals using streptozotocin (STZ) administration. The mandibular tissues were collected and processed. The jawbone density was evaluated with micro-CT. Osteocyte lacunae were effectively acquired and identified using backscattered electron scanning microscopy (BSE). A significantly decreased osteocyte lacunae size was found in the diabetic group. Using the acid etching method, it was demonstrated that the area of osteocyte and lacunae, and the pericellular areas were both significantly reduced in the diabetes group. In conclusion, a standard and relatively reliable method for analyzing osteocyte/lacunae morphological changes under compromised conditions has been successfully established. This method demonstrates that diabetes can significantly decrease osteocyte/lacunae size in a pig’s mandibular cancellous bone.
