The Epidemiology, Associated Factors and Bacterial Profile of Asymptomatic Bacteriuria in Pregnant Women: A Retrospective Chart Review Study in Saudi Arabia

Purpose Asymptomatic bacteriuria (ASB) is the presence of significant amounts of bacteria within the urinary tract in the absence of urinary tract infection (UTI) symptoms, resulting in negative neonatal and pregnancy consequences. This study determined the prevalence, bacteriology patterns, and associated factors with ASB among pregnant women in both primary and hospital levels of care in the Eastern Province of Saudi Arabia. Methods This retrospective chart review study included pregnant women between 18 and 50 years who performed the screening urine culture test during their first antenatal visit between 2017 and 2021, without UTI symptoms. The collected data involved the demographic, medical, and obstetric characteristics, and urine culture results. T-tests and chi-squared tests were used for bivariate associations followed by binary logistic regression models. Results ASB was positive among 03.42% of the 6471 pregnant women included in the study. Logistic regression revealed that the risk of positive ASB increased in pregnant women in the first and second trimesters (OR = 2.04, 95% CI = 1.41–2.93 and OR= 1.50, 95% CI = 1.03–2.19, respectively), as well as pregnant women with a history of previous UTI (OR = 2.98, 95% CI = 2.14–4.15). The predominant organism isolates were E. coli, followed by GBS, Klebsiella pneumoniae, and Enterococcus faecalis. Conclusion With limited data on ASB among pregnant women in Saudi Arabia, findings from the current study could help decision-makers in the country assess the epidemiological characteristics of the condition. Further study is recommended to investigate the susceptibility patterns of commonly prescribed antibiotics with different uropathogens to guide the clinicians who deal with these cases. Additionally, a large national study across the other regions in the kingdom is suggested to calculate the prevalence of ASB in Saudi Arabia.

Safety monitoring of COVID‐19 vaccines: perspective from the European Medicines Agency

Prior to deployment of coronavirus disease 2019 (COVID‐19) vaccines in the European Union in 2021, a high vaccine uptake leading to an unprecedented volume of safety data from spontaneous reports and real‐world evidence, was anticipated. The European Medicines Agency (EMA) implemented specific activities to ensure enhanced monitoring of emerging vaccine safety information, including intensive monitoring of reports of adverse events of special interest and the use of observed‐to‐expected analyses. The EMA also commissioned several independent observational studies using a large network of electronic healthcare databases and primary data collection via mobile and web‐based applications. This preparedness was key for two high‐profile safety signals: thrombosis with thrombocytopenia syndrome (TTS), a new clinical entity associated with adenovirus‐vectored vaccines, and myocarditis/pericarditis with messenger RNA vaccines. With no existing case definition nor background rates, the signal of TTS posed particular challenges. Nevertheless, it was rapidly identified, evaluated, contextualized and the risk minimized thanks to close surveillance and an efficient use of available evidence, clinical expertise and flexible regulatory tools. The two signals illustrated the complementarity between spontaneous and real‐world data, the former enabling rapid risk identification and communication, the latter enabling further characterization. The COVID‐19 pandemic has tremendously enhanced the development of tools and methods to harness the unprecedented volume of safety data generated for the vaccines. Areas for further improvement include the need for better and harmonized data collection across Member States (e.g., stratified vaccine exposure) to support signal evaluation in all population groups, risk contextualization, and safety communication.
Prospective studies on artificial intelligence (AI)-based diabetic retinopathy screening

study designs and the primary outcomes, the results of these studies still pointed toward the similar and positive directions of AI as a valuable tool for large-scale DR screening (6,7,9). The first AI algorithm that received approval from United States Food and Drug Administration (FDA) was IDx-DR, which was reported as having sensitivity of 87.2% [95% confidence interval (CI): 81.8–91.2%], specificity of 90.7% (95% CI: 88.3– 92.7%) using the Early Treatment Diabetic Retinopathy Study photography as standard (10), and imageability rate (percentage of participants with a completed human grading and with a disease level AI system output) of 96.1% (95% CI: 94.6–97.3%) in detect more than mild non-proliferative diabetic retinopathy (NPDR) and diabetic macular edema (DME) (11). Among the current AI screening systems for DR, a head-to-head comparative study on diagnostic performance of these systems demonstrated the sensitivity, specificity
Wind Power Generation Scenarios in Lebanon

Renewable energy in terms of solar and wind energy can be an essential part of Lebanon's strategies to add new capacity, increase energy security, address environmental concerns, and resolve the electricity crisis. In this regard, there is an urgent need to develop road maps in order to reduce the effect of global warming and enhance sustainable technological development for generating clean power in the country. Therefore, the present paper evaluates Lebanon's wind energy generation potential as an alternative solution to supply electricity to households in various locations distributed over Lebanon. In the present study, the measured data are used to evaluate the wind energy potential in Lebanon and to find suitable locations to install wind farms in the country. Accordingly, the results demonstrated that Ain ed Dabaa is the most suitable location for the installation of a wind farm. Moreover, the study aims to develop a wind energy cost analysis techno-economic model for eight conventional wind turbines and a Barber wind turbine, which was found to be very competitive. Consequently, this study showed that the implementation of a wind turbine could provide clean, economical, and continuous production of electricity in countries that suffer from daily blackouts.
A switched high-Tc superconductor microstrip resonator using a MEM switch

We have used a high performance (less than 0.05 dB insertion loss, greater than 30 dB isolation) high-Tc superconductor based micro electromechanical (MEM) switch to insert a shunt microstrip resonator into a microstrip transmission line thus forming a 'T'-resonator structure. This allows the insertion of a series of notches and peaks (depending on termination of the shunt line and the harmonic in use) into the transmission line's transfer function thus forming a rudimentary switched filter. The 'T'-resonator is designed for a resonant frequency of 3.5 GHz and is implemented using high-Tc YBa2Cu3O7, BaTiO3 is used as a dielectric patch underneath a suspended gold membrane. The design, fabrication, testing and most recent results are presented in this paper.
Crystallization and Structural Properties of Oleogel-Based Margarine

Interest in oleogel as a promising alternative to traditional hydrogenated vegetable oil has increasingly grown in recent years due to its low content of saturated fatty acids and zero trans fatty acids. This study aimed to develop wax-based margarine to replace traditional commercial margarine. The wax-based margarine was prepared and compared with commercial margarine in texture, rheology, and microscopic morphology. The possibility of preparing margarine at room temperature (non-quenched) was also explored. The results showed that the hardness of oleogel-based margarine increased as the BW concentration increased. Denser droplets and crystal network structure were observed with the increase in BW content. XRD patterns of oleogel-based margarine with different content BW were quite similar and structurally to the β′ form. However, the melting temperature of oleogel-based margarine was over 40 °C at each concentration, which represented a poor mouth-melting characteristic. In addition, the unique, improved physical properties of oleogel-based margarine were obtained with binary mixtures of China lacquer wax (ZLW) and Beeswax (BW), due to the interaction of the ZLW and BW crystal network. The rapid cooling process improved the spreadability of oleogel-based margarine. The margarine prepared by 5% BW50:ZLW50 had similar properties to commercial margarine in texture and melting characteristics (37 °C), which had the potential to replace commercial margarine.
Nitrogen dependence of band alignment and electrical properties of HfTiON gate dielectrics metal-oxide-semiconductor capacitor

The effect of nitrogen incorporation on the band alignment and electrical properties of HfTiO gate dielectric complementary metal-oxide-semiconductor (MOS) capacitors has been investigated by spectroscopy ellipsometry, x-ray photoelectron spectroscopy, and electrical measurements. Reduction in optical band gap and band offsets has been detected. However, improved electrical properties have been achieved from HfTiON gate dielectric MOS capacitors attributed to the nitrogen-induced reduction in oxygen-related traps and the improved interface quality. Although there is a nitrogen-induced reduction in band gap and band offset, the sufficient barrier heights still makes HfTiON a promising high-k gate dielectric candidate for proposed near-future complementary metal-oxide-semiconductor applications.
Strategic management of local potential-based entrepreneurship through community empowerment on fish attractions Bendhung Lepen in Mrican Village Yogyakarta

This research was aimed (1) to know the internal environmental factors that affect the management of entrepreneurship strategies for fish tourism attraction Bendhung Lepen; (2) to know external environmental factors that affect the management of entrepreneurship strategies for fish tourism attraction Bendhung Lepen; and (3) to know the appropriate marketing system for the location of Bendhung Lepen fish attractions. The method used in this study was qualitative descriptive where data were obtained by means of interviews, observations, and documentation. The interview was conducted at random on visitors to fish attraction Bendhung Lepen, the community around the Gajah Wong river irrigation site, and the Bendhung Lepen Community. Field results were used for SWOT analysis consisting of IFAS tables, EFAS tables, IE matrices, and SWOT matrices. The results of the analysis on IFAS can be known that the score for internal factors of 3.43 which understands the internal condition of management of fish attraction management in Bendhung Lepen falls into the moderate category (average). This is because factors that have a high score were at high operational cost points. The results of the EFAS analysis showed a score of 3.28 which means the external condition of Bendhung Lepen fish attractions were in good condition, where the most dominant factor is the number of competitors was still small, balanced crop sales, and the density of the number of tourist attraction visitors.
A Combined Hipparcos and Multichannel Astrometric Photometer Study of the Proposed Planetary System of ρ Coronae Borealis

Hipparcos and Multichannel Astrometric Photometer (MAP) observations of ρ Coronae Borealis independently display astrometric motion at the period of the proposed "extrasolar planetary" companion to the star. Individual least-squares fits to each astrometric data set yield independent estimates of the semimajor axis, inclination, and node angle that are in excellent agreement. A combined solution of the Hipparcos and MAP data yields an inclination of 0. °5, a node at 30.5 ± 12.4, and a semimajor axis of 1.66 ± 0.35 mas, indicating a companion mass of 0.14 ± 0.05 M☉, over 2 orders of magnitude greater than the minimum mass for the companion as determined by radial velocity studies. This mass is approximately that of an M dwarf star; the companion cannot be a planetary object.
On the Use of Satellite Altimeter Data in Argo Quality Control

Abstract Satellite altimeter measurements are used to check the quality of the Argo profiling floats time series. The method compares collocated sea level anomalies from altimeter measurements and dynamic height anomalies calculated from Argo temperature and salinity profiles for each Argo float time series. Different kinds of anomalies (sensor drift, bias, spikes, etc.) have been identified on some real-time but also delayed-mode Argo floats. About 4% of the floats should probably not be used until they are carefully checked and reprocessed by the principal investigators (PIs). The method appears to be very complementary to the existing quality control checks performed in real time or delayed mode. It could also be used to quantify the impact of the adjustments made in delayed mode on the pressure, temperature, and salinity fields.
Bacterial crystalline cellulose secretion via a supramolecular BcsHD scaffold

Cellulose, the most abundant biopolymer on Earth, is not only the predominant constituent of plants but also a key extracellular polysaccharide in the biofilms of many bacterial species. Depending on the producers, chemical modifications, and three-dimensional assemblies, bacterial cellulose (BC) can present diverse degrees of crystallinity. Highly ordered, or crystalline, cellulose presents great economical relevance due to its ever-growing number of biotechnological applications. Even if some acetic acid bacteria have long been identified as BC superproducers, the molecular mechanisms determining the secretion of crystalline versus amorphous cellulose remain largely unknown. Here, we present structural and mechanistic insights into the role of the accessory subunits BcsH (CcpAx) and BcsD (CesD) that determine crystalline BC secretion in the Gluconacetobacter lineage. We show that oligomeric BcsH drives the assembly of BcsD into a supramolecular cytoskeletal scaffold that likely stabilizes the cellulose-extruding synthase nanoarrays through an unexpected inside-out mechanism for secretion system assembly.
High-frequency chaotic solutions for a slowly varying dynamical system

In this article we study the asymptotic dynamics of highly oscillatory solutions for the unbalanced Allen–Cahn equation with a slowly varying coefficient. We describe the underlying structure of these solutions through a function we call the adiabatic profile, which accounts for the asymptotic area covered by the solutions in the phase space. In finite intervals, we construct solutions given any adiabatic profile. In the case of a periodic coefficient we show that the system has chaotic behavior by constructing high-frequency complex solutions which can be characterized by a bi-infinite sequence of real numbers in $[c_1,c_2]\cup\{ 0\}\ (0
Reynolds number dependence of Lagrangian statistics in large numerical simulations of isotropic turbulence

Lagrangian statistics are reported from a direct numerical simulation database with grid resolution up to 20483 and Taylor-scale Reynolds number approximately 650. The approach to Lagrangian Kolmogorov similarity at high Reynolds number is studied using both the velocity structure function and frequency spectrum. A significant scaling range is observed for the latter which is consistent with recent estimates of 6–7 for the scaling constant C 0. In contrast to some previous results at low Reynolds number, the current results suggest that at high Reynolds number the dissipation autocorrelation is a two-scale process influenced by both the Lagrangian velocity integral time scale and Kolmogorov time scale. Results on the logarithm of the pseudo-dissipation are in support of its modeling as a diffusion process with one-time Gaussian statistics. As the Reynolds number increases, the statistics of dissipation and enstrophy become more similar while their logarithms have significantly longer time scales.
Real Gas Computation Using an Energy Relaxation Method and High-Order WENO Schemes

In this paper, we use a recently developed energy relaxation theory by Coquel and Perthame and high order weighted essentially nonoscillatory (WENO) schemes to simulate the Euler equations of real gas. The main idea is an energy decomposition under the form e=e1+e2, where e1is associated with a simpler pressure law (γ-law in this paper) and the nonlinear deviation e2is convected with the flow. A relaxation process is performed for each time step to ensure that the original pressure law is satisfied. The necessary characteristic decomposition for the high order WENO schemes is performed on the characteristic fields based on the e1γ-law. The algorithm only calls for the original pressure law once per grid point per time step, without the need to compute its derivatives or any Riemann solvers. Both one- and two-dimensional numerical examples are shown to illustrate the effectiveness of this approach.
Improvement of superconducting properties of Bi-2212 round wire and primary test results of large capacity Rutherford cable

We have developed HTS cables using Bi-2212 round wires, which have high mechanical strength and an average J/sub c/ of 200 kA/cm/sup 2/ at 4.2 K in self-field. Four designs of cables were fabricated in this work and those tables could carry I/sub c/ values from 1 kA to 10 kA at 4.2 K and self-field depending on the number of strands. A 70m-long 20-strand Rutherford cable was successfully manufactured. Optimization of heat treatment conditions was effective to reduce I/sub c/ degradation observed in the case of heat treatment with a long length. I/sub c/ values of a Rutherford cable were measured under loading at 4.2 K in 4 T. The critical values of the stress on face loading and edge loading were 60 MPa and 100 MPa, respectively. We successfully obtained high J/sub c/ value of 500 kA/cm/sup 2/, which was almost double that of the conventional wires capitalize "Rutherford".
Nutrition Coverage in Medical Licensing Examinations in Germany: An Analysis of Six Nationwide Exams

The state of nutrition education in medicine is inadequate, with nutrition-related topics being poorly integrated into lectures. Most medical students receive only a few contact hours of nutrition instruction during their entire time at medical school. Identifying potential barriers that may explain the paucity of nutritional knowledge in medical students is thus of paramount importance. The extent of nutrition coverage in the second part of Germany’s nationwide medical licensing exam is currently unknown. We addressed this issue and assessed nutrition content, as well as students’ scores, in this pivotal test prior to their graduation. We performed a post hoc analysis of six nationwide medical licensing examinations (2018–2020) undertaken by 29,849 medical students and screened 1920 multiple-choice questions for nutrition-related content. Nutrition-related questions accounted for a minority of the questions (2.1%, n = 40/1920). A considerable number of the questions (n = 19) included only a single nutrition-related answer option that was frequently incorrect and served as a distractor. About 0.5% of questions were entirely nutrition related. Despite undeniable barriers, the inclusion of additional nutrition-related examination questions could serve as an incentive to engage students and medical schools in enhancing medical nutrition education. The recently published competence-oriented learning objective catalog in Germany could play a pivotal role in this context, leading to better recognition of nutrition-related topics in medical education.
Nonlinear stratified spin-up

Both a weakly nonlinear analytic theory and direct numerical simulation are used to document processes involved during the spin-up of a rotating stratified fluid driven by wind-stress forcing for time periods less than a homogeneous spin-up time. The strength of the wind forcing, characterized by the Rossby number ε, is small enough (i.e. ε[Lt ]1) that a regular perturbation expansion in ε can be performed yet large enough (more specifically, ε∝E1/2, where E is the Ekman number) that higher-order effects of vertical diffusion and horizontal advection of momentum/density are comparable in magnitude. Cases of strong stratification, where the Burger number S is equal to one, with zero heat flux at the upper boundary are considered. The Ekman transport calculated to O(ε) decreases with increasing absolute vorticity. In contrast to nonlinear barotropic spin-up, vortex stretching in the interior is predominantly linear, as vertical advection negates stretching of interior relative vorticity, yet is driven by Ekman pumping modified by nonlinearity. As vertical vorticity is generated during the spin-up of the fluid, the vertical vorticity feeds back on the Ekman pumping/suction, enhancing pumping and vortex squashing while reducing suction and vortex stretching. This feedback mechanism causes anticyclonic vorticity to grow more rapidly than cyclonic vorticity. Strict application of the zero-heat-flux boundary condition leads to the growth of a diffusive thermal boundary layer E−1/4 times thicker than the Ekman layer embedded within it. In the Ekman layer, vertical diffusion of heat balances horizontal advection of temperature by extracting heat from the thermal boundary layer beneath. The flux of heat extracted from the top of the thermal boundary layer by this mechanism is proportional to the product of the Ekman transport and the horizontal gradient of the temperature at the surface. The cooling caused by this heat flux generates density inversions and intensifies lateral density gradients where the wind-stress curl is negative. These thermal gradients make the potential vorticity strongly negative, conditioning the fluid for ensuing symmetric instability which greatly modifies the spin-up process.
Dynamic simulations of hard-sphere suspensions under steady shear

We have studied the flow of suspensions of solid spheres under steady shear using a newly developed flow simulator. For the first time, the complicated interplay between hydrodynamic interactions and solids' variable configuration under flow conditions in which large departures from equilibrium configurations occur can be simulated in full 3D. For volume fractions up to 35%, viscosities have been obtained that are in excellent agreement with experiments reported in the literature.
