A multi-disciplinary approach for uranium exploration using remote sensing and airborne gamma-ray spectrometry data in the Gebel Duwi area, Central Eastern Desert, Egypt
Authors: Hegab Mahmoud Abd El-Rahman
Published: August 2024

Uranium exploration plays a pivotal role in meeting global energy demands and advancing nuclear technology. This study presents a comprehensive approach to uranium exploration in the Gebel Duwi area of the Central Eastern Desert of Egypt, utilizing remote sensing and airborne gamma-ray spectrometric data. Multispectral remote sensing techniques, including Principal Component Analysis (PCA), Minimum Noise Fraction (MNF), and Band Ratioing (BR), are employed to identify lithological units and hydrothermal alteration zones associated with uranium deposition, such as iron oxides, argillic, propylitic, and phyllic alterations. Additionally, airborne gamma-ray spectrometry data provide insights into the spatial distribution of radioelements, including uranium (eU), thorium (eTh), and potassium (K), as well as radioelement ratios (eU/eTh, eU/K, and eTh/K). The uranium migration index map (eU-(eTh/3.5)) and the F-parameter map (K*(eU/eTh)) have been generated to investigate the movement of uranium within various geological zones and characterize anomalous uranium concentrations. Statistical analyses, including mean (X), standard deviation (S), and coefficient of variability (C.V.), are conducted to identify uranium-rich zones. The integration of these datasets enables the generation of a uranium potential map highlighting areas of elevated concentrations indicative of uranium mineralization. Field observations and mineralogical analyses of collected samples validate our findings, confirming the presence of minerals associated with uranium mineralization in mapped high-potential areas. The significance of minerals like Fe-Chlorite, Fe-Mg-Chlorite, ferrihydrite, goethite, calcite, muscovite, dolomite, actinolite, vermiculite, and gypsum in indicating potential uranium mineralization processes underscores the importance of our results.

Published: August 2024

To determine the distribution of keratometry and corneal astigmatism (CA) and their association with demographic factors, systemic parameters, anthropometric measures, ocular biometric indices, and refractive errors in people aged 60 years and above. In this cross-sectional study, 160 clusters were randomly selected from Tehran city (Iran) using the multi-stage cluster sampling method. All participants underwent optometric examinations including testing uncorrected and best-corrected distance visual acuity, non-cycloplegic autorefraction, and subjective refraction. Pentacam imaging for all participants was carried out using Pentacam AXL. Keratometry and CA were reported based on Pentacam’s data. The average, standard deviation (SD) and 95% confidence interval (CI) of flat keratometry (Kf), steep keratometry (Ks), mean keratometry (mean K), and CA were 44.02 ± 1.58 D (95% CI 43.94–44.1), 44.86 ± 1.67 D (95% CI 44.78–44.94), 44.44 ± 1.58 D (95% CI 44.36–44.52), and 0.84 ± 0.74 D (95% CI 0.81–0.87), respectively. The 95% and 99% percentiles of mean K were 47.1 and 48.6 D, respectively. According to the multiple generalized estimating equation model, the mean K was significantly higher in males, in myopes, and in those with higher systolic blood pressure. Moreover, the mean K was inversely related to the axial length, height, anterior chamber depth (ACD), corneal diameter, and central corneal thickness (CCT). The prevalence of various types of CA based on a cut-off > 0.50 D was as follows; with-the-rule: 32.5% (95% CI 30.6–34.4), against-the-rule: 18.2% (95% CI 16.7–19.7), and oblique: 10.0% (95% CI 9.1–11.0). The present study investigated the normal distribution of keratometry and CA in individuals ≥ 60 years, and results can be used in clinical matters, especially in intraocular lens power calculation. Sex, systolic blood pressure, height, and some biometric components such as ACD, corneal diameter, and CCT were significantly related to keratometry and should be considered.

Sex differences and age-related changes in the human heart at the tissue, cell, and molecular level have been well-documented and many may be relevant for cardiovascular disease. However, how molecular programs within individual cell types vary across individuals by age and sex remains poorly characterized. To better understand this variation, we performed single-nucleus combinatorial indexing (sci) ATAC- and RNA-Seq in human heart samples from nine donors. We identify hundreds of differentially expressed genes by age and sex and find epigenetic signatures of variation in ATAC-Seq data in this discovery cohort. We then scale up our single-cell RNA-Seq analysis by combining our data with five recently published single nucleus RNA-Seq datasets of healthy adult hearts. We find variation such as metabolic alterations by sex and immune changes by age in differential expression tests, as well as alterations in abundance of cardiomyocytes by sex and neurons with age. In addition, we compare our adult-derived ATAC-Seq profiles to analogous fetal cell types to identify putative developmental-stage-specific regulatory factors. Finally, we train predictive models of cell-type-specific RNA expression levels utilizing ATAC-Seq profiles to link distal regulatory sequences to promoters, quantifying the predictive value of a simple TF-to-expression regulatory grammar and identifying cell-type-specific TFs. Our analysis represents the largest single-cell analysis of cardiac variation by age and sex to date and provides a resource for further study of healthy cardiac variation and transcriptional regulation at single-cell resolution.

The nature of data obtainable from the commercial smartphone – bolstered by a translational model emphasizing the impact of social and physical zeitgebers on circadian rhythms and mood – offers the possibility of scalable and objective vital signs for major depression. Our objective was to explore associations between passively sensed behavioral smartphone data and repeatedly measured depressive symptoms to suggest which features could eventually lead towards vital signs for depression. We collected continuous behavioral data and bi-weekly depressive symptoms (PHQ-8) from 131 psychiatric outpatients with a lifetime DSM-5 diagnosis of depression and/or anxiety over a 16-week period. Using linear mixed-effects models, we related depressive symptoms to concurrent passively sensed behavioral summary features (mean and variability of sleep, activity, and social engagement metrics), considering both between- and within-person associations. Individuals with more variable wake-up times across the study reported higher depressive symptoms relative to individuals with less variable wake-up times (B [95% CI] = 1.53 [0.13, 2.93]). On a given week, having a lower step count (−0.16 [−0.32, −0.01]), slower walking rate (−1.46 [−2.60, −0.32]), lower normalized location entropy (−3.01 [−5.51, −0.52]), more time at home (0.05 [0.00, 0.10]), and lower distances traveled (−0.97 [−1.72, −0.22]), relative to one’s own typical levels, were each associated with higher depressive symptoms. With replication in larger samples and a clear understanding of how these components are best combined, a behavioral composite measure of depression could potentially offer the kinds of vital signs for psychiatric medicine that have proven invaluable to assessment and decision-making in physical medicine. Clinical Trials Registration: The data that form the basis of this report were collected as part of clinical trial number NCT03152864.

Published: August 2024

This article proposes a holistic and improved methodology for the inductors' design in power electronic circuits operating at high frequencies. This methodology includes an analytical design, a finite element modeling of the electromagnetic behavior with JMAG software, a simulation analysis in a Simulink environment, and experimental verification of the effectiveness of inductor design in a laboratory‐scale step‐up boost power converter prototype. The holistic approach allowed us to achieve all target specifications such as maximum power (300 W), minimum voltage (60 V), inductance (1.77 mH), and maximum current ripple (1 A). It guarantees the losses' minimization in core and copper (21.47 W), and marginal errors below 4% between the analytical, simulated, and experimental values.
Resilient robust model predictive load frequency control for smart grids with air conditioning loads
Authors: Jike Shiluo , Liu Guobao , Li Feng , Zhang Changyu , Wang Qi , Zhou Mengxia , Qian Haiya
Published: August 2024

This paper investigates the robust model predictive load frequency control problem for smart grids with wind power under cyber attacks. To accommodate intermittent power generation, the demand response of the system is considered by involving the air conditioning loads in the frequency regulation. In addition, the system uncertainties produced by the air conditioning load users and wind turbines when replacing traditional generator sets are considered. By using the cone complementary linearization algorithm and the linear matrix inequality technique, a resilience robust model predictive control strategy with mixed performance indexes is proposed. Furthermore, a rigorous derivation of the recursive feasibility of robust model predictive control is given. Finally, the simulation results of the two‐area load frequency control scheme show that the proposed model predictive control strategy is capable of realizing the load frequency control of the multi‐area smart grid and is robust to the parameter uncertainties and frequency regulation of the system. The results also show that the proposed model predictive control strategy has some resistance to cyber attacks and external disturbances.
A robust must‐run capacity identifying approach in power system dispatch considering interdependence with natural gas system
Authors: Wu Wenqi , Xiao Yunpeng , Hu Tao , Wang Xiuli
Published: August 2024

Identifying the must‐run capacity (MRC) could help to accelerate the unit commitment and assess market power, thus critical for achieving an efficient power system dispatch. However, the existing approaches identify the MRC without considering the ever‐strengthening interdependence between power system and natural gas (NG) system, as well as neglecting either the uncertainties of renewables or the constraints on start‐up/shut‐down states for thermal units. To fill the gaps, this article proposes a novel model and methodology for identifying the MRC in power system considering the interdependence with NG system, with adopting a distributionally robust (DR) approach to consider the uncertainties of renewables. A constraint‐generation based algorithm is devised to solve the model, with a relax‐round‐polish based Alternating Direction Method of Multipliers (ADMM) algorithm to address the interaction between the two energy systems. Comparative studies show the effectiveness in MRC assessment over the existing approaches.
A robust bi‐level programming approach for optimal planning an off‐grid zero‐energy complex
Authors: Ghaffarpour Reza , Zamanian Saeid
Published: August 2024

Electric power provision for all the customers is not always possible for distribution companies. Some customers are interested in serving their load through renewable resources regarding the climate situation. Electrically off‐grid zero‐energy building is an applicable concept, in which the electrical energy provision of the buildings is isolated from the power supply infrastructures. This paper introduces a robust bi‐level programming model to create a cost‐effective off‐grid zero energy complex in Kish Island under risk management. The upper level of the planning is composed of two components, the passive design of buildings within the complex and the design of a stand‐alone energy system. The passive design as an energy‐saving tool includes the selection of insulation material for building external walls and finding the optimum thickness. Also, the stand‐alone energy system design denotes the sizing of diesel generator, photovoltaic, and battery energy storage as the distributed energy resources. The lower‐level problem optimally handles the annual scheduling of these resources to meet the complex demand under the impact of passive cooling. The Karush–Kuhn–Tucker condition method is used to solve this bi‐level planning problem. Furthermore, the battery degradation is concerned via the throughput model to consider the replacement cost of the problem.

A secondary analysis of the Life After Pediatric Sepsis Evaluation prospective cohort study was performed. This study included children <18 years admitted to 12 U.S. Pediatric Intensive Care Units with community-acquired septic shock requiring vasoactive–inotropic support and invasive or noninvasive ventilation who survived discharge. The primary outcome of sleep deterioration was characterized as any increased trouble in sleeping measured by a question from the Pediatric Quality of Life Inventory (PedsQL) at baseline compared with the response at the 3-month follow-up. Child and parent variables were evaluated for association with sleep deterioration using univariable and multivariable analyses. Of the original 389 patients, 229 survived for 3 months and completed the PedsQL. The final cohort included 111 children who had available follow-up data at month 3 and did not report baseline sleep challenges. Overall, 25% (28/111) of children reported declines in sleep at 3 months. There were no patient or illness characteristics associated with sleep decline at 3 months in univariable analysis. In multivariable models controlling for age, sex, insurance type, baseline complex conditions, and immunocompromise, no measures of illness severity were associated with deterioration in sleep at 3 months. Sleep deterioration is common in survivors of community-acquired septic shock but detection may be difficult to identify without routine screening.

El abordaje anterior directo (AAD) se ha convertido en una opción cada vez más popular entre los cirujanos ortopédicos para realizar una artroplastia total de cadera (ATC). El AAD proporciona un medio menos invasivo para acceder a la articulación de la cadera, lo que se traduce en una recuperación más temprana de la función para muchos pacientes después de una ATC. A pesar de su atractivo, sigue habiendo preocupación en la comunidad ortopédica con respecto a una curva de aprendizaje para aquellos que no están capacitados formalmente en el uso del AAD. Esta llamada curva de aprendizaje se ha asociado con un período de aumento de complicaciones como mala alineación de los componentes, aumento de la pérdida de sangre operatoria, necesidad de revisión temprana, entre otras.

Aquí se describe un enfoque reproducible paso a paso para realizar el AAD con el uso de una mesa de tracción y fluoroscopia con arco en C. Creemos que con un período de estudio dedicado, una cuidadosa atención a los detalles, desde la colocación del paciente hasta las liberaciones capsulares y la preparación ósea, y un plan para el aprendizaje continuo, muchas de las complicaciones antes mencionadas se pueden evitar durante la transición de la práctica al uso del AAD para ATC.

Introduction Pseudomonas aeruginosa is one of the important opportunistic nosocomial pathogens that are increasingly becoming resistant to many drugs including the drugs of last resort, carbapenems, and colistin.

Methods The study involved the examination of clinical isolates of P. aeruginosa recovered from diabetic patients for the presence of acquired genes implied in carbapenem and colistin resistance.

Results A total of 100 clinical isolates from diabetic patients' wound and sputum were investigated for their susceptibility to imipenem and colistin followed by phenotypic assay and resistance gene screening. The study revealed 27 sputum isolates being resistant to imipenem further confirmed by a modified Hodge test and 28 wound isolates were resistant to colistin. The resistant isolates of wound and sputum were found to possess blaOXA-48
, blaVIM
, mcr-1, and mcr-5 genes. The strains had a coexistence of carbapenem- and colistin-resistant genes.

Conclusion Considering the fact that infection by such resistant isolates in diabetics could be frightening, clinical laboratories must employ rapid diagnostic methods to detect resistance which can aid in the treatment decision-making.
Giant Cystic Pneumocytoma in a Young Male: Rare Diagnostic Conundrum with Clinicoradiological and Histopathological Features

Pulmonary sclerosing pneumocytoma is a rare benign neoplasm typically seen in middle-aged women. The exact preoperative diagnosis is quite challenging considering its nonspecific clinical and radiologic features along with complex histology. Moreover, obtaining an exact histopathological diagnosis can be difficult especially with the small biopsy specimens. Most patients are generally asymptomatic with incidental detection of peripheral, homogenous, solitary pulmonary nodule. It is essential to differentiate it from other mimickers including malignant lesions as limited surgical resection is curative in these cases without adjuvant therapy. We present a rare giant cystic variant of pneumocytoma, in a young male, which was initially mimicking inflammatory myofibroblastic tumor even on preoperative histology.
Moral attitudes towards effort and efficiency: a comparison between American and Chinese history

In some cultures, merely exerting effort is considered virtuous, even when the effort is inefficient. Our study examines how this moral attitude towards effort (relative to efficiency) has evolved historically across two distinct sociopolitical and linguistic contexts: the People’s Republic of China and the United States, using natural language processing techniques. Specifically, two formal political corpora were used—the People’s Daily (1950–2021) and the Congressional speeches for the U.S. (1873–2011). We developed dictionaries for each concept based on pre-trained word embedding models in both languages. Moral attitudes towards effort and efficiency were calculated on a year-by-year basis as the cosine similarity between the dictionaries of these concepts and an existing dictionary of morality. We benchmarked the fluctuations of moral attitude towards inefficient effort against critical historical events in the two countries. Additional time series analysis and Granger tests revealed the association and potential directionality between the evolution of moral attitude towards inefficient effort and critical socio-cultural variables such as collectivism and cultural looseness. Our research sheds light on the historical and socio-cultural roots of moralization of effort and has implications for historical psychology research on moral attitudes.

To address the issue of a single gradient direction in the gradient design of triply periodic minimal surfaces, two functional gradient schemes, trapezoidal and W-shaped, were proposed based on the stress distribution range of the uniform thickness porous structure model using the primitive minimal surface porous structure. These structures were manufactured using a photosensitive resin through stereolithography additive manufacturing technology. Through finite element analysis and experimental validation, it was observed that as porosity decreases, the bending resistance of the uniform thickness model increases. The designed functional gradient porous structures were compared with the uniform thickness model. The results show that the designed gradient porous structure has a higher strength and bending stiffness than the uniform thickness porous structure. The proposed design can improve the bending performance of the porous structure. The W-shaped gradient porous structure with fine control of porosity variation range had better ability to improve structural bending performance than the trapezoidal gradient design.

In field of diffuse optics for biomedical applications, the spatial sensitivity (SS) is a key parameter to evaluate or optimize the adopted modalities, such as penetration depth, signal-to-noise ratio as well as sensor distribution. Nevertheless, SS is usually estimated via computer simulations (e.g., photon Monte Carlo simulation), rather than being quantified experimentally, due to the technical difficulty. In this study, we report the experimental measurement and visualization of optical SS through combination of acoustic radiation force (ARF) and the scanning diffuse correlation spectroscopy (DCS). By spatially varying the location of ARF focal spot within liquid phantom, the enhanced particle flow, which represents the most spatial sensitive location, was identified by DCS. The experimental outcomes were cross-validated with the photon Monte Carlo simulation, thus demonstrating its accuracy, feasibility, and potential for guiding clinical usage.

Published: August 2024

The transmission characteristics of terahertz (THz) waves in a non-uniform microplasma are investigated by using the scattering matrix method. The electron density distribution in microplasma is simulated by Epstein and parabolic models. The effects of physical parameters, such as the incidence angle of THz waves, microplasma size, electron density, and collision frequency, on the propagation of THz waves are numerically analyzed. The results show that lower frequency THz waves are difficult to penetrate the microplasma with high electron density and high collision frequency. The microplasma density distribution, especially the gradient variation of the density in the first layer, has a large effect on the reflection of THz waves. Thus, THz waves can be used to diagnose the physical parameters of microplasmas.

Sagittally focusing x-ray crystal spectrometers with elliptical profiles in the meridional (x-ray dispersion) plane are proposed for plasma diagnostics in experiments accompanied by high neutron yields. The spectrometers feature a variable sagittal radius of curvature to ensure the sagittal focusing of rays for each photon energy in a chosen detection plane. The detector is placed after the ray crossing point at the second ellipse focus, and the source-to-detector distance is maximized to reduce the neutron-induced background. The elliptical shape imposes a limitation on the spectrometer geometry such that the influence of the source size on the spectral resolution can be avoided only for a demagnifying spectrometer (the source-to-crystal distance is larger than that of crystal-to-detector). Hence, two designs are proposed. The first design, featuring high magnification and limited spectral resolution can be suitable for x-ray continuum spectroscopy. The second design of high demagnification is optimized for spectral resolution, and can be used for time-resolved spectroscopy of plasma’s characteristic emission lines using streak cameras. The key performance characteristics of the two designs are verified using ray tracing.

Published: August 2024

Two-dimensional (2D) van der Waal (vdW) magnets are gaining significance in exploring fundamental condensed matter physics and developing cutting-edge technologies. Here, we report the structural and magnetic properties of the antiferromagnetic semiconductor MnPSe3 crystal. Intriguing magnetic behaviors and the strong anisotropy of the bulk crystal have been investigated through temperature-dependent magnetization studies along with the observation of Néel temperature at TN=70±2 K. At temperatures below TN, the bulk MnPSe3 exhibits field-induced spin-flop phase transitions with a spin-flop field (HSF) of nearly 8 kOe at 5 K. These transitions are evidenced from isothermal magnetization measurements conducted at low temperatures. Moreover, temperature-dependent enhancement in HSF was also studied. Our findings motivate the exploration of intrinsic magnetic interactions in 2D MnPSe3 and incorporating it into functional vdW heterostructures and devices.

A pioneering 4-channel, high-k poloidal, millimeter-wave collective scattering system has been successfully developed for the Experimental Advanced Superconducting Tokamak (EAST). Engineered to explore high-k electron density fluctuations, this innovative system deploys a 270 GHz mm-wave probe beam launched from Port K and directed toward Port P (both ports lie on the midplane and are 110° part), where large aperture optics capture radiation across four simultaneous scattering angles. Tailored to measure density fluctuations with a poloidal wavenumber of up to 20 cm−1, this high-k scattering system underwent rigorous laboratory testing in 2023, and the installation is currently being carried out on EAST. Its primary purpose lies in scrutinizing ion and electron-scale instabilities, such as the electron temperature gradient (ETG) mode, by furnishing measurements of the kθ (poloidal wavenumber) spectrum. This advancement significantly bolsters the capacity to probe high-k electron density fluctuations within the framework of EAST. Beam tracing and data interpretation modules developed for both EAST and NSTX-U high-k scattering diagnostics are described.
