Myocarditis Following COVID-19 Vaccination: A Systematic Review

COVID-19 vaccination has significantly reduced both the morbidity and mortality rates associated with SARS-CoV-2 infection. Vaccines, especially mRNA vaccines, have been proposed in several studies to complicate viral myocarditis. Thus, our systematic and meta-analysis review aims to further investigate the possibility of an association between COVID-19 vaccines and myocarditis. We systematically searched PubMed, Web of Science, Scopus, Ovid, and Google Scholar and did a gray search of other databases using the following keywords and terms: "Myocarditis ("Myocarditis" Mesh) OR "Chagas Cardiomyopathy" Mesh) AND "COVID-19 Vaccines" Mesh. The studies were limited to only English articles that reported myocardial inflammation or myocarditis associated with COVID-19 vaccines. Pooled risk ratio with its 95% confidence interval was analyzed by RevMan software (5.4) to perform the meta-analysis. Our study included 671 patients from 44 studies with a mean age of 14-40 years. Nevertheless, myocarditis was noted in a mean of (3.227) days, and 4.19 per million vaccination recipients experienced myocarditis. Most cases were clinically presented with manifestations of cough, chest pain, and fever. Laboratory tests revealed increased C-reactive protein, and troponin with all other cardiac markers in most patients. Cardiac magnetic resonance imaging (MRI) revealed late gadolinium enhancement with myocardial edema and cardiomegaly. Also, electrocardiograms revealed ST-segment elevation in most patients. Furthermore, the incidence of myocarditis was statistically significantly lower in the COVID-19 vaccine group as compared with the control group (RR = 0.15, 95% CI = 0.10-0.23, p-value < 0.00001). No significant association was found between COVID-19 vaccines and the incidence of myocarditis. The study's findings highlight the importance of implementing evidence-based COVID-19 prevention strategies, such as vaccination, to reduce the public health impact of COVID-19 and its associated complications.
Adolescents’ In-Person and Online Interactions With Friends During the COVID-19 Pandemic: Associations With Loneliness and Depressive Symptoms

Abstract:Adolescents’ interactions with friends were severely disrupted during stay-at-home orders associated with the COVID-19 pandemic. The current study (N = 144, 49% female, 80% European American) considered adolescents’ perceptions of this disruption and the implications of the disruption for their emotional adjustment. Adolescents reported that not seeing friends was the most distressing consequence of the pandemic. Compared to before the pandemic, adolescents reported a large decrease in in-person interactions with friends, which was related to loneliness. There was a small increase in online interactions, which could counteract the effects of fewer in-person interactions, but only if the interactions felt socially connected. Online interactions lacking social connection were related to greater loneliness and depressive symptoms.
Explicit Simulations of the Intertropical Convergence Zone

Abstract The intertropical convergence zone (ITCZ) is one of the most important components of the global circulation. In order to understand the dynamical processes that regulate its formation, latitudinal preference, and structure, explicit two-dimensional numerical modeling of convection on an equatorial beta plane was conducted with a nonhydrostatic cloud-system-resolving model. The model was forced by energy fluxes associated with constant sea surface temperature (SST) and by horizontally homogeneous radiative cooling. Two distinct patterns were identified for the spatial distribution of convective activity in the Tropics. The first was characteristic of enhanced off-equator convection, namely, a double ITCZ-like morphology (one more salient than the other) straddling the equator during the early period of the integration. The second featured enhanced equatorial convection, namely, a single ITCZ-like morphology on the equator during the later quasi-equilibrium period. Diagnostic analysis and two addit.
Influences of Seedling Age and Variety on the Growth and Bulb Yield of Onion in Northwest Ethiopia

Onion is one of the major cash crops and helps improve the livelihoods of smallholder farmers. Although genetically and morphologically different, seedlings of all released onion varieties are transplanted at the ages ranging from 40 to 50 days, which contributes to the low level of productivity in Ethiopia. Therefore, a field experiment was conducted at the research site of Fogera National Research and Training Center during the 2019/20 irrigation season with the objective of identifying the optimum seedling age for improved onion productivity in Northwest Ethiopia. The treatments consisted of three varieties (Adama red, Bombay red, and Nasik red) and four seedling ages (30, 40, 50, and 60 days) of onion, which were laid down in 3 × 4 factorial arrangement using randomized complete block design with three replications. Growth and yield parameters of onion were collected based on the standard procedures and analyzed using SAS version 9.6. The results revealed that both variety and seedling age significantly ( P < 0.001 ) influenced plant height, leaf number, bulb diameter, fresh bulb weight, and marketable bulb yield, while their interaction effect did not influence these parameters. Days to maturity was significantly ( P < 0.001 ) affected by main as well as by the interaction effects of variety and seedling age. Younger seedling took longer time to mature, while older seedlings matured relatively early. The seedlings of Bombay red variety at 60 days age gave the earliest maturity days (105.33 days) compared to the other combinations. The highest plant height (50.18 cm), leaf number (12.00), bulb diameter (53.47 mm), bulb weight (84.39 g), and marketable bulb yield (29.97 t/ha) were recorded from Bombay red variety where the marketable yield recorded from Nasik red was statistically similar with that of Bombay red variety. Seedlings with 60 days old performed best in terms of all the tested growth and yield parameters including the highest marketability (32.03 t/ha). Accordingly, 60 days old seedlings and Bombay red and Nasik red varieties can be used to increase the productivity of onion in the study area and areas with similar agroecology.
Rupture Geometry and Slip Distribution of the Mw 7.2 Nippes Earthquake, Haiti, From Space Geodetic Data

On 14 August 2021 the Mw 7.2 Nippes earthquake struck southern Haiti, rupturing a segment of the Enriquillo‐Plantain Garden Fault system (EPGF), a 300 km‐long strike‐slip fault system that accommodates half of the highly oblique convergence displacement between the Caribbean and the North American plates. We use coseismic surface displacements from Interferometric Synthetic Aperture Radar and Global Navigation Satellite System (GNSS) to estimate the geometry of the rupture through a systematic parametric exploration, determine its mechanism, and relate them to the regional tectonics derived from interseismic GNSS measurements. We show that the earthquake ruptured a north dipping fault (66 ± 4° dip) with a geodetically determined moment release that is 40% reverse and 60% strike‐slip. We cannot conclude whether this north‐dipping structure is the EPGF itself or a distinct fault running parallel to the EPGF. The rupture then evolved to the west on a vertical (86 ± 2° dip) fault parallel to the EPGF, the Ravine du Sud fault, with left‐lateral strike‐slip motion. The coseismic slip distribution of the 2010 Léogane and 2021 Nippes earthquakes, consistent with the transpressional interseismic strain rate field, show a segmentation of the Caribbean–North American plate boundary in southern Haiti and imply a revision in our understanding of the mode of earthquake rupture within the EPGF system.
COVID-19: The Challenge of Global Vaccine Inequity

Abstract:Several safe and effective COVID-19 vaccines were developed, evaluated, and made available in record time during the pandemic. But hopes of equitable access to COVID-19 vaccines were dashed by corporate greed, political expediency, global trade agreements, and intellectual property ownership, delaying or denying access for poor countries. Once vaccines became widely available, their benefits were curtailed by anti-science sentiment and anti-vaccine conspiracy theories. Building trust in science is key to preparing for the next pandemic.
Mobility enhancement in graphene transistors on low temperature pulsed laser deposited boron nitride

Low temperature pulsed laser deposited (PLD) ultrathin boron nitride (BN) on SiO2 was investigated as a dielectric for graphene electronics, and a significant enhancement in electrical transport properties of graphene/PLD BN compared to graphene/SiO2 has been observed. Graphene synthesized by chemical vapor deposition and transferred on PLD deposited and annealed BN exhibited up to three times higher field effect mobility compared to graphene on the SiO2 substrate. Graphene field effect transistor devices fabricated on 5 nm BN/SiO2 (300 nm) yielded maximum hole and electron mobility of 4980 and 4200 cm2/V s, respectively. In addition, significant improvement in carrier homogeneity and reduction in extrinsic doping in graphene on BN has been observed. An average Dirac point of 3.5 V and residual carrier concentration of 7.65 × 1011 cm−2 was observed for graphene transferred on 5 nm BN at ambient condition. The overall performance improvement on PLD BN can be attributed to dielectric screening of charged im.
Equilibrium distributions for an open migration process

Summary We consider a system of colonies in which migration, immigration and emigration take place according to a fairly general rule. Necessary and sufficient conditions for equilibrium are given in the theorem of Section (3). The equilibrium distribution of colony numbers is determined by Equations (7) and (9); the colony sizes are thus statistically independent in equilibrium. Attention is also paid to the case where one colony becomes a “bottleneck” to circulation, when equilibrium changes character
Impact of interest rate differential, exchange rate changes and political stability on Foreign capital inflow in Nigeria: Discrete threshold regression model

Abstract Lack of investable capital has slowed down the development process in many developing nations, including Nigeria, and this has sparked empirical research on the factors affecting foreign capital flow. Therefore, the purpose of this study was to investigate the effects of interest rate differential, exchange rate changes, and political stability on the entrance of foreign capital into Nigeria between 1981 and 2021. To investigate the impact of the factors on foreign capital inflow in regimes with low and high interest rate differentials, the study used a discrete threshold regression model (DTRM). The study discovered an interest rate differential threshold value of 3.68 percent, indicating that an interest rate differential high and over the predefined threshold promotes a favorable and considerable inflow of foreign capital into the nation. Additionally, the country’s capital inflow is influenced by political stability and exchange rate fluctuations. The implication is that investors evaluate a country’s IRD in relation to other risk factors (political and macroeconomic) and will only invest if the IRD is higher than3.68 percent since it will balance out other opportunity costs at home and risk factors in the receiving country’s economy.
Local existence with mild regularity for the Boltzmann equation

Without Grad's angular cutoff assumption, the local existence of classical solutions to the Boltzmann equation is studied. There are two new improvements: the index of Sobolev spaces for the solution is related to the parameter of the angular singularity; moreover, we do not assume that the initial data is close to a global equilibrium. Using the energy method, one important step in the analysis is the study of fractional derivatives of the collision operator and related commutators.
A new model of the L–H transition in tokamaks

A new model of the L–H transition in tokamaks is proposed, based on the criterion that the transition occurs when plasma turbulence and shear Alfvén waves compete in the vicinity of the last-closed flux surface. The model is used to predict the scaling of the H-mode access power, PL–H, with magnetic and plasma variables. The predictions are in good agreement with the experimental scaling of PL–H with plasma size, density, magnetic field and edge safety factor (plasma current). They are also qualitatively consistent with the dependence of PL–H on ion mass and charge, limiter versus divertor plasmas, single versus double null configurations, the divertor leg length and H–L versus L–H hysteresis. Most notably, the model explains the appearance of the minimum in PL–H with plasma density (in terms of the transition between sheath limited and conduction limited scrape-off layer (SOL) transport) and correctly predicts the scaling of the density minimum with magnetic field and Greenwald number. Finally, the effect of toroidal field reversal is included by making the normalized correlation length of the eddy and maximum safety factor in the edge-SOL layer functions of B × ∇B direction.
Spontaneous Resolution of Tractional Retinal Detachment in a Type II Diabetic Patient

A 43 years old male with diabetes type II was under treatment for diabetic retinopathy with extramacular tractional retinal detachment (TRD) in the left eye OS. During the follow-up visit, the patient had a drop in vision from 20/25 to 20/60. The TRD was found to have progressed to involve the macula and was threatening the fovea; therefore, vitrectomy was thought to be inevitable. Meanwhile, the patient adopted exercise and tight glycemic control, and during the preoperative evaluation of three months duration, we observed resolution of traction and return of visual acuity to baseline (20/20). In conclusion, spontaneous resolution of TRD is extremely rare. If it occurs, the patient may be spared from undergoing a vitrectomy.
Determinants of Household Food Insecurity and Depression in Mothers: Evidence from Ghana

Background. Household food insecurity (FI) and maternal depression are serious public health problems, especially in low-income countries. The aims of this study were to determine the determinants of household FI and depression in mothers and the association between these constructs in Savelugu Municipality, Ghana. Methods. An analytical, community-based, cross-sectional survey was conducted to collect data on 364 mothers of under-five children selected using the multistage method in the municipal. Household FI and maternal depression were measured using the FI Experience Scale and Patient Health Questionnaire 9-item in personal interviews. Logistic regression analysis was used to identify the factors associated with household FI and maternal depression and the association between these two constructs. Results. The mean age of mothers was 30.1(±6.5) years with almost all practising Islamic religion (96.2%) and were married (96.7%). The prevalence of household FI and maternal depression were 51.6% and 25.3%, respectively. The determinants of household FI were mother’s self-health rating, social support, nutrition knowledge, and household’s source of drinking water, while those of maternal depression were the mother’s work, place of residence, self-health rating, and nutrition knowledge. In multivariable adjusted logistic regression analysis, women in food insecure households were about three times more likely than women in food secure households to be depressed (adjusted odds ratio = 2.49; 95% confidence interval: 1.36–4.55; and p = 0.003 ). Conclusion. The current study shows a high prevalence of both household FI and depression in mothers in Savelugu Municipality. Both personal and household characteristics of the women are associated with household FI and maternal depression statuses, and the two constructs are highly correlated. It is recommended to include depression assessment in interventions for FI.
VIL Density as a Hail Indicator

Abstract In current severe thunderstorm warning operations, forecasters frequently use the vertically integrated liquid water content (VIL) product from the WSR-88D to estimate thunderstorm severity and, particularly, hail size. Since VIL varies greatly based on airmass characteristics, forecasters have typically determined a threshold VIL to be used for each new thunderstorm event. A product that is independent of airmass characteristics, and thus independent of season and geographic location, would be more desirable in an operational warning environment. It has been observed that high-topped thunderstorms with high VILs do not always produce large hail. It has also been observed that low-topped thunderstorms with low VILs occasionally do produce large hail. However, the maximum reflectivity in both high-topped and low-topped thunderstorms is similar when both produce similar-sized hail. From this, it was hypothesized that dividing the VIL by the echo top would “normalize” the VIL and produce a common va.
Steady laminar Couette flow of a dilatant fluid along a channel with suction at a bounding wall

We consider a special dilatant fluid model for which the apparent viscosity can be expressed as a polynomial in the second scalar invariant of the rate of strain tensor. The model has been used to investigate the steady plane Couette flow of a non-Newtonian fluid through a channel with suction, assumed small, at the lower porous wall. The introduction of a similarity transformation in the perturbed governing partial differential equations of the flow leads to a system of coupled non-linear ordinary differential equations. The solutions of these equations have been obtained analytically as a power series in the suction parameter α. The combined effects of the non-Newtonian and the suction parameters on the longitudinal and transverse velocity profiles as well as the skin friction, have been discussed. The validity of the analytical solutions has also been checked with the corresponding numerical solutions for small values of the governing parameters.
Centrifugal, barotropic and baroclinic instabilities of isolated ageostrophic anticyclones in the two-layer rotating shallow water model and their nonlinear saturation

Abstract Instabilities of isolated anticyclonic vortices in the two-layer rotating shallow water model are studied at Rossby numbers up to two, with the main goal to understand the interplay between the classical centrifugal instability and other ageostrophic instabilities. We find that different types of instabilities with low azimuthal wavenumbers exist, and may compete. In a wide range of parameters, an asymmetric version of the standard centrifugal instability has larger growth rate than the latter. The dependence of the instabilities on the parameters of the flow, i.e. Rossby and Burger numbers, vertical shear and the ratios of the layers’ thicknesses and densities, is investigated. The zones of dominance of each instability are determined in the parameter space. Nonlinear saturation of these instabilities is then studied with the help of a high-resolution finite-volume numerical scheme, by using the unstable modes identified from the linear stability analysis as initial conditions. Differences in nonlinear development of the competing centrifugal and ageostrophic barotropic instabilities are evidenced. A nonlinear mechanism of axial symmetry breaking during the saturation of the centrifugal instability is displayed.
Comportement asymptotique des marches aleatoires associees aux polynomes de Gegenbauer et applications

Random walks on N associated with orthogonal polynomials have properties similar to classical random walks on . In fact such processes have independent increments with respect to a hypergroup structure on with a convolution and a Fourier transform which is the basic tool for their study. We illustrate these ideas by giving a description of the asymptotic behaviour (CLT and ILL) of the random walks associated with Gegenbauer's polynomials. Moreover we can then use these random walks as a reference scale to deduce asymptotic properties of other Markov chains on via a comparison theorem which is of independent interest.
Analysis of Off-Nuclear X-Ray Sources in Galaxy NGC 4945

Recently, X-ray astronomy has been used to investigate objects such as galaxies, clusters of galaxies, Active Galactic Nuclei (AGN), quasars, starburst superbubbles of hot gas, X-ray binary systems, stars, supernova remnants, and interstellar and intergalactic material. By studying the x-ray emission patterns of these objects, we can gain a greater understanding of their structure and evolution. We analyze X-ray emission from the galaxy NGC 4945 using data taken by the Chandra X-ray Observatory. The Chandra Interactive Analysis of Observations (CIAO) software package was used to extract and fit energy spectra and to extract light curves for the brightest off-nuclear sources in two different observations of NGC 4945 (January, 2000 and May, 2004). A majority of sources were closely fit by both absorbed power law and absorbed bremsstrahlung models, with a significantly poorer {chi}{sup 2}/dof for the absorbed blackbody model, and most sources had little variability. This indicates that the sources are accreting binary systems with either a neutron star or black hole as the compact object. The calculated luminosities were about 10{sup 38} erg/s, which implies that the mass of the accreting object is close to 10 solar masses and must be a black hole.
Some new applications of the GLPD micromorphic model of ductile fracture

This paper presents some new applications of a model of ductile rupture of porous ductile materials proposed by Gologanu, Leblond, Perrin and Devaux (GLPD). The first application is concerned with the relationship between this model and the class of generalized standard materials. We show that the GLPD model fits in this class, provided that the porosity is not allowed to change and the hypothesis of linearized theory is adopted. The advantage of this property is that it automatically warrants the unicity of the solution for the ‘projection’ problem of the (supposedly) elastic stress predictor onto the GLPD’s yield locus. The second application leads to some exact analytical solutions of the GLPD model constitutive equations for the problems of an elastic hollow sphere in the framework of linearized theory, and viscous in large deformations. Comparisons between the numerical predictions of the GLPD model and the analytical solutions confirm the robustness of the numerical scheme used to implement this model into SYSTUS© finite element (FE) code. Thus, these exact analytical solutions can be used to validate the implementation of the GLPD model in another finite element code. In the third application, comparisons between experimental and numerical load vs. displacement curves for an axisymmetric pre-cracked specimen made of a typical stainless steel are found to yield satisfactory results.
