تصويرية المكان الموسعة في رواية (ظلال الجفر)
Authors: الكولي أميرة شايف علي
Published: January 2025

تهدف هذه الدراسة إلى ضبط مفهوم (الصورة السردية) في رواية (ظلال الجفر) من خلال دراسة صورة المكان بوصفه مكونا أساسيا يجمع بين حدوده عناصر العمارة السردية للصورة. وقد عرض هذا البحث لجملة من المطالب توزعت في فصل واحد، عرض المطلب الأول منها لأيقونتي القرية والمدينة، أما الثاني فقد تناول الصورة الأيقونية في كل من المنزل والبيت، في حين تناول المطلب الثالث: التصوير الأيقوني في الغرفة والمعتزل. وقد كشفت هذه الأيقونات عن أن أهمية المكان بوصفه عنصرا لازما في تكوين الصورة السردية في رواية (ظلال الجفر)، و بثت الرواية من خلاله صورا دقيقة لتفاصيل كثيرة ألمت بها، خاصة وأن التصوير المكاني قد احتل مساحة واسعة من السرد يمكن لها أن تشكل الحدود الملموسة له في صورة فنية مستقلة. وتوصل البحث من خلال ذلك إلى استقلالية التصوير السردي عن التصوير البلاغي الضيق، إضافة إلى أن(المكان) في الرواية كان صورة حية تنبض من خلال علائق الأشخاص، وتوالي الأحداث في تفاعل تصويري متتابع استطاع الوصول بــ(الصورة السردية) إلى شط آخر يتحرر من سدانة البلاغة القديمة وسلطتها ويحط في عتبة المصطلح بمفهومه الموسع.

Published: January 2025

L’évaluation de l’enseignement par les étudiant.e.s (ÉEÉ) demeure le principal outil utilisé pour estimer les compétences du corps professoral ; leur embauche, leur agrégation et leur promotion, tant aux États-Unis qu’au Canada, malgré les critiques formulées à l’égard de sa légitimité et sa validité en tant qu’instrument de mesure. Cependant, une littérature abondante et majoritairement en anglais dénonce la présence de biais qui compromettent les résultats des ÉEÉ avec pour corollaire des pratiques discriminatoires envers les femmes, les personnes racisées et les personnes issues d’autres groupes marginalisés. Cet article présente un résumé de cette littérature et fait quelques suggestions pour de futures recherches.
Разрушение хрупких балок при антисимметричном четырехточечном изгибе
Authors: Кургузов Владимир Дмитриевич , Кузнецов Денис Александрович
Published: January 2025

The nucleation of cracks in structural elements during their service life is due to the degradation of the material or the presence of hidden defects. The structure therefore loses its original load-bearing capacity and fails under significantly lower external loads. As a rule, the fracture of structures due to crack growth occurs under mixed loading. In this paper, an eccentric beam of rectangular cross-section with an edge crack subjected to antisymmetric four-point loading is considered. By changing the position of the crack relative to the center of the beam, it is possible to obtain the entire range of mixed fracture modes: I+II, pure I and pure II modes. Using the finite element method, stress intensity coefficients for modes I and II of failure, as well as T-stresses, were obtained for different geometric parameters of the beam and different loading conditions. The length of the crack, its position relative to the beam center, and the length of the short span were varied. The methods commonly used for calculating T-stresses were analyzed. In the element closest to the crack tip, strong displacement oscillations, not mentioned in the literature, are observed, therefore to determine T-stresses with the highest possible accuracy it is suggested to calculate them from displacements, cutting off the 3-4 nodes closest to the crack tip. Experimental studies of the fracture toughness of ebonite in a mixed mode were carried out. For each type of loading and geometry, 3-5 identical specimens were tested. The tests were carried out under static load until the specimens were completely destroyed. In all experiments, the crack initiation angle and critical load were recorded. Six failure criteria were used to predict both failure direction and critical load: the generalized maximum tangential stress criterion, the extended maximum tangential strain criterion, the generalized strain energy density criterion, the generalized maximum averaged stress criterion, the maximum elastic energy release rate criterion and the generalized maximum elastic energy release rate criterion. The results obtained demonstrate good agreement between the experimental values of critical loads and the numerical calculations. The error in determining the crack initiation angle does not exceed 5%. Considering that the experimental results agree with the predictions of failure criteria for the beam subjected to antisymmetric four-point bend loading, this type of a beam specimen can be used to study mixed-type fracture in the elements manufactured from engineering materials, such as, for example, plexiglass, ebonite, and getinax.

The article is devoted to the study of the possibilities of the modern version of the third-generation wind-wave model WAVEWATCH III (WW3). The basic equations of the model are given and the software implementation is described. A retrospective analysis of the characteristics of wind waves in the Sea of Azov was carried out, and the simulation results were compared with the data from long-term observations of coastal hydrometeostations of the Sea of Azov, presented in the Unified Interdepartmental Federal Information System (ESIMO) databases. In the predictive model, the computational domains approximating the shoreline configuration and the bathymetry of real marine basins are regular latitude-longitude grids consisting of elements of size 1.2 x 1.2 degree (about 2 x 2 km). The bathymetry and the corresponding land-sea mask (a two-dimensional array with values determining the belongingness of an element to ground or sea) required to do calculations for each of the basins were constructed using navigation maps. In the retrospective analysis, climatic data for a multi-year month (2008-2023) on wind speed were used to generate input wind data at grid nodes. Based on the WW3 spectral model, the forecast of wind wave parameters in the Sea of Azov was carried out. Prognostic maps of the average period, average length and heights of the waves prevailing at different points in time were constructed. The meteorological fields (wind speed, water and air temperature) necessary for calculations were taken from the databases of the Hydrometeorological Center of Russia and NCEP/NOAA. Parallel efficiency indicators for hybrid parallelization (MPI-OpenMP) were calculated, and scalability was determined for both MPI and hybrid launches.

Hydrodynamics and heat transfer in mixed convection of liquid metal (Pr=0.025) in a vertical pipe with an upward flow in a transverse magnetic field are considered. The study was carried out using a direct numerical simulation method. Simulations were performed at Reynolds numbers up to 12,000, Richardson numbers from 0 to 2.4 and Hartmann numbers up to 550 for two limiting cases of pipe wall conductivity. The simulation results for an isolated pipe were compared with the measurement data from the mercury experiments. The effect of the transverse magnetic field is manifested in the suppression of turbulent transfer and flow laminarization with the formation of strong inhomogeneity of the longitudinal velocity profile by angle and gradients of the streamwise velocity in the transverse direction. Depending on the pipe wall conductivity and the ratios of such parameters as Richardson and Hartmann numbers, the resulting flows with different topology of the longitudinal velocity profile determine the wall temperature distribution in the wall and the values of the heat transfer coefficients. It is shown that in a magnetic field in the case of isolated walls with an increase in the Richardson number the flow has a tendency to instability, which develops in the jets formed in the region of Roberts layers. The periodic process of development and breakage of jets leads to the emergence and development of vortex structures that persist in the magnetic field and cause fluctuations in the velocity and temperature components in the flow. The dependence of the friction factor and heat transfer (Nusselt number) on the Richardson number is obtained.

Authors: Kasana Abhishek , Dwivedi Aishwarya , Verma Vaishali
Published: January 2025

Viruses cause infectious diseases in humans, ranging from mild to life-threatening. Early and accurate diagnosis is essential for timely treatment and prevention of complications. Diagnostic methods typically rely on detecting viral genetic material, proteins, or the host’s immune response, depending on the infection stage. Monoclonal antibodies, known for their specificity and high affinity, are widely used for diagnosing viral infections by enabling precise and sensitive detection of viral proteins. This review explores the applications of monoclonal antibody-based methods for detecting viral infections, emphasizing their pivotal role as sensitive detection reagents. These methods are crucial for developing robust immunodiagnostic assays capable of diagnosing various viral diseases in human, animal, and plant hosts, with special emphasis on SARS-CoV-2. The review also explores various assays that employ monoclonal antibodies for diagnostic purposes and the technologies used for their production. Understanding the principles and applications of monoclonal antibodies in diagnosing viral diseases is essential for implementing effective public health interventions and preventing future pandemics.

Ribosome biogenesis is vital for sustaining stem cell properties, yet its regulatory mechanisms are obscure. Herein, we show unique properties of zebrafish
meioc
mutants in which spermatogonial stem cells (SSCs) do not differentiate or upregulate rRNAs. Meioc colocalized with Piwil1 in perinuclear germ granules, but Meioc depletion resulted in Piwil1 accumulation in nucleoli. Nucleolar Piwil1 interacted with 45S pre-rRNA.

Authors: Sarmah Parindita , Deshmukh Prasad , Gaurkar Sagar
Published: January 2025

Nevus Sebaceous of Jadassohan (NSJ) is a hamartoma that presents as a cutaneous lesion, which can be considered an overgrowth of sebaceous glands, hair follicles, and other epidermal structures. Although it is usually a benign condition, the lesion is capable of producing secondary neoplasms, both benign and infrequently, malignant. This case report discusses a 21-year-old male patient who presented with a lesion on the forehead, manifesting as a pilonidal sinus due to the presence of a tuft of hair at the end of the sinus tract following childhood trauma. The presence of a sinus tract with hair growth in the glabellar region is a rare and diagnostically challenging presentation of NSJ. This case highlights the complexities of managing such chronic wounds and the potential complications arising from trauma.

Authors: Akinsola Folasade Aanuoluwapo , Amapu Ishaku Yo’ila , Madukaihe Madu Josephine , Oyinlola Eunice Yemisi
Published: January 2025

A 119-day laboratory incubation study was conducted to evaluate microbial biomass dynamics in soil amended with different leaf litters. The treatments included five leaf litter sources: African mahogany (Khaya senegalensis), Mango (Mangifera indica), Beechwood (Gmelina arborea), Red River Gum (Eucalyptus camaldulensis), and a mixed litter treatment, arranged in a Completely Randomized Design with three replicates. Chemical properties of the leaf litters, including organic carbon, nitrogen, sulfur, potassium, calcium, sodium, magnesium, total soluble polyphenols, and lignin content, were analyzed. Soil microbial biomass carbon (SMBC) and nitrogen (SMBN) were determined using the chloroform fumigation incubation (FI) method.
Among the treatments, Eucalyptus camaldulensis exhibited the highest C:N ratio (33.3), while Gmelina arborea showed the lowest (20.6). Significant differences (p<0.05) were observed across leaf litter types and weeks for soil microbial carbon and nitrogen parameters. Soil amended with Eucalyptus camaldulensis recorded the highest microbial biomass carbon (122.85 mg kg⁻¹), significantly (p<0.05) exceeding the values for mixed leaf litter, control, Gmelina arborea, Khaya senegalensis, and Mangifera indica.
The highest microbial biomass nitrogen values were observed in soils amended with Khaya senegalensis (13.90 mg kg⁻¹) and Mangifera indica (13.25 mg kg⁻¹), with the control treatment yielding the lowest value. Eucalyptus camaldulensis amended soil also had the highest microbial biomass C:N ratio, followed by Mangifera indica, Gmelina arborea, the mixed treatment, and the control. The results suggest that Mangifera indica, Khaya senegalensis, and the mixed leaf litter have a greater potential to enhance soil microbial nitrogen, while Eucalyptus camaldulensis promotes higher carbon activity in the soil.

Background: Regular unscheduled low-acuity visits to the emergency departments (ED) significantly cause crowding and prolonged wait times, adversely affecting patient outcomes.
Aims: This study analyzes trends in non-emergency visits to emergency departments (EDs) in the USA and Canada over five years, focusing on the impact of socio-demographic factors and primary care accessibility.
Methodology: A retrospective cross-sectional study; Using datasets from CIHI (Canada) and NCHS (USA), it identifies disparities in ED utilization across age, sex, and race, as well as the effects of the COVID-19 pandemic on visit frequencies.
Results: There are significant correlations between age and low-acuity visits, with females visiting more frequently in Canada and males in the USA. Pandemic-related changes led to a reduction in low-acuity visits by approximately 3.6% in the USA and 3.8% in Canada. A chi-square test of independence showed a significant relationship between age and triage levels at presentation (c.l= 0.95, p value = 0.05).
Conclusion: The study underscores the need for policy interventions to enhance primary care access and reduce ED overcrowding. Further research is recommended to explore systemic factors influencing healthcare-seeking behavior.

Objective

To quantify the effect of corticosteroids compared to lidocaine‐only injections over 12 weeks among patients with knee osteoarthritis (KOA).

Methods

Participants with KOA were randomized to receive a knee injection of methylprednisolone acetate 1 mL (40 mg) plus 2 mL lidocaine (1%) or 1 mL saline and 2 mL lidocaine. Participants and providers were blinded to treatment allocation using an opacified syringe. The outcome was the average change from baseline of the total Knee Injury and Osteoarthritis Outcome Score (KOOS) (range 0‐100) assessed at 2‐week intervals over 12 weeks. Participants received KOOS questionnaires on their smartphones through a web‐based platform. We used linear mixed‐effects regressions with robust variance estimators to evaluate the association between the intervention and change in KOOS total and subscales (ClinicalTrials.gov identifier NCT03835910; registered 2019‐02‐11).

Results

Of the 33 randomized participants, 31 were included in the final analysis. The predicted mean (SE) change in total KOOS over the 12‐week follow‐up was 9.4 (3.2) in the corticosteroids arm versus −1.3 (1.4) in the control arm (P = 0.003). Of participants, 47% achieved change as large as the minimal clinically important difference (16 units) in the intervention arm compared to 6% of participants in the lidocaine arm. Further, there were greater improvements in the intervention arm for KOOS subscales and for Patient Reported Outcomes Measurement Information System (PROMIS) assessments of pain intensity, behavior, and interference.

Conclusion

Corticosteroid injections demonstrated clinically meaningful improvements in KOA symptoms over 12 weeks of follow‐up. These data support larger studies to better quantify short‐term benefits.
Microfabrication Approaches on Magnetic Shape Memory Films
Authors: Kar Satyakam , Nielsch Kornelius , Fähler Sebastian , Reith Heiko
Published: September 2023

Magnetic shape memory alloys are emerging multifunctional materials that enable applications like high‐stroke actuation, solid‐state refrigeration, and energy harvesting of waste heat. Thin films of these alloys promise integration in microsystems to exploit their multifunctional properties at the microscale. However, the microfabrication process of these Heusler alloys is difficult. Herein, different etching techniques are investigated for the microfabrication of epitaxial Ni‐Mn‐Ga films, the encountered challenges are explained, and ways to overcome them are demonstrated. The results show that wet chemical etching is suitable for large patterned structures, while reactive ion etching of Ni‐Mn‐Ga films is unsuitable due to redeposition. For patterning structures below 10 μm with clean and sharp edges, the best results are obtained by ion beam etching with adjusted sample‐stage tilt. Finally, a microfabrication process using Si microtechnology to fabricate partially freestanding structures is demonstrated. These findings give guidelines for the fabrication and integration of these smart materials in Si‐based microsystems.

Published: September 2023

In this study, a multispectral light‐field imaging system is developed using nematic liquid‐crystal microlens arrays (LC‐MLAs). The system solves the spectral under‐sampling and complex system issues in existing light‐field and spectral cameras. The LC‐MLA is the core optical element of the snapshot imaging system. No dispersion or customized scanning machinery is required to obtain multispectral light fields. Deep learning technology is utilized to reconstruct spectral information from raw data. In the experiments, it is demonstrated that the proposed method efficiently reconstructs multispectral data with 10 nm accuracy in the visible wavelength range of 400–700 nm.

High‐entropy spinel oxides (HESOs) are a promising class of electrocatalysts whose material properties and catalytic activity can be finely tuned by controlling the elemental composition. Although numerous HESOs are already reported, their compositions are primarily limited to the first‐row transition metals. Herein, the synthesis of a high‐entropy spinel (CrFeCoNiMo)3O4 nanosheet (HEO‐NS) and its application as oxygen evolution reaction (OER) catalyst are reported. The high‐entropy spinel displays a low overpotential of 255.3 mV at a current density of 10 mA cm−2 and excellent stability, outperforming the IrO2 benchmark. Careful analysis with X‐ray photoelectron spectroscopy (XPS) and X‐ray absorption spectroscopy (XAS) reveals that the incorporation of high‐valence Cr and Mo can activate the lattice oxygen by weakening the metal–oxygen bond and promoting the lattice oxygen mechanism (LOM). Furthermore, the catalyst can achieve a high current density of 1 A cm−2 at 1.71 V in a lab‐scale electrolyzer, demonstrating the potential of HESOs for practical application.

Conversion of sunlight and organic carbon substrates to sustainable energy sources through microbial metabolism has great potential for the renewable energy industry. Despite recent progress in microbial photosynthesis, the development of microbial platforms that warrant efficient and scalable fuel production remains in its infancy. Efficient transfer and retrieval of gaseous reactants and products to and from microbes are particular hurdles. Here, inspired by water lily leaves floating on water, a microbial device designed to operate at the air–water interface and facilitate concomitant supply of gaseous reactants, smooth capture of gaseous products, and efficient sunlight delivery is presented. The floatable device carrying Rhodopseudomonas parapalustris, of which nitrogen fixation activity is first determined through this study, exhibits a hydrogen production rate of 104 mmol h−1 m−2, which is 53 times higher than that of a conventional device placed at a depth of 2 cm in the medium. Furthermore, a scaled‐up device with an area of 144 cm2 generates hydrogen at a high rate of 1.52 L h−1 m−2. Efficient nitrogen fixation and hydrogen generation, low fabrication cost, and mechanical durability corroborate the potential of the floatable microbial device toward practical and sustainable solar energy conversion.

The development of nonprecious metal catalysts to meet the activity‐stability balance at industrial‐grade large current densities remains a challenge toward practical alkali‐water electrolysis. Here, this work develops an orderly nanodendritic nickel (ND‐Ni) catalyst that consists of ultrafine nanograins in chain‐like conformation, which shows both excellent activity and robust stability for large current density hydrogen evolution reaction (HER) in alkaline media, superior to currently applied Raney nickel (R‐Ni) catalyst in commercial alkali‐water electrolyzer (AWE). The ND‐Ni catalyst featured by a three‐dimensional (3D) interconnecting microporous structure endows with high specific surface area and excellent conductivity and hydrophilicity, which together afford superior charge/mass transport favorable to HER kinetics at high current densities. An actual AWE with ND‐Ni catalyst demonstrates durable water splitting with 1.0 A cm−2 at 1.71 V under industrial conditions and renders a record‐low power consumption of 3.95 kW h Nm−3 with an energy efficiency close to 90%. The hydrogen price per gallon of gasoline equivalent (GGE) is calculated to be ≈$0.95, which is less than the target of $2.0 per GGE by 2026 from the U.S. Department of Energy. The results suggest the feasibility of ND‐Ni substitute for R‐Ni catalyst in commercial AWE.

A photo‐induced metal‐free radical hydroboration of various styrenes with NHC‐borane has been developed, which can provide mono‐ and di‐alkylated boranes in a selective manner. Besides, this strategy can also be applied to prepare di‐functionalized boranes with two different alkyl groups. Mild reaction conditions and good functional groups compatibility were observed. Preliminary mechanism for this reaction was proposed.

The extracellular environment defines a physical boundary condition with which cells interact. However, to date, cell response to geometrical environmental cues is largely studied in static settings, which fails to capture the spatiotemporally varying cues cells receive in native tissues. Here, a photoresponsive spiropyran‐based hydrogel is presented as a dynamic, cell‐compatible, and reconfigurable substrate. Local stimulation with blue light (455 nm) alters hydrogel swelling, resulting in on‐demand reversible micrometer‐scale changes in surface topography within 15 min, allowing investigation into cell response to controlled geometry actuations. At short term (1 h after actuation), fibroblasts respond to multiple rounds of recurring topographical changes by reorganizing their nucleus and focal adhesions (FA). FAs form primarily at the dynamic regions of the hydrogel; however, this propensity is abolished when the topography is reconfigured from grooves to pits, demonstrating that topographical changes dynamically condition fibroblasts. Further, this dynamic conditioning is found to be associated with long‐term (72 h) maintenance of focal adhesions and epigenetic modifications. Overall, this study offers a new approach to dissect the dynamic interplay between cells and their microenvironment and shines a new light on the cell's ability to adapt to topographical changes through FA‐based mechanotransduction.

Here, a sucrose non‐fermenting‐1‐related protein kinase alpha subunit (TaSnRK1α‐1A) is identified as associated with cold stress through integration of genome‐wide association study, bulked segregant RNA sequencing, and virus‐induced gene silencing. It is confirmed that TaSnRK1α positively regulates cold tolerance by transgenes and ethyl methanesulfonate (EMS) mutants. A plastid‐lipid‐associated protein 6, chloroplastic‐like (TaPAP6L‐2B) strongly interacting with TaSnRK1α‐1A is screened. Molecular chaperone DJ‐1 family protein (TaDJ‐1‐7B) possibly bridged the interaction of TaSnRK1α‐1A and TaPAP6L‐2B. It is further revealed that TaSnRK1α‐1A phosphorylated TaPAP6L‐2B. Subsequently, a superior haplotype TaPAP6L‐2B30S/38S is identified and confirmed that both R30S and G38S are important phosphorylation sites that influence TaPAP6L‐2B in cold tolerance. Overexpression (OE) and EMS‐mutant lines verified TaPAP6L positively modulating cold tolerance. Furthermore, transcriptome sequencing revealed that TaPAP6L‐2B‐OE lines significantly increased jasmonic acid (JA) content, possibly by improving precursor α‐linolenic acid contributing to JA synthesis and by repressing JAR1 degrading JA. Exogenous JA significantly improved the cold tolerance of wheat plants. In summary, TaSnRK1α profoundly regulated cold stress, possibly through phosphorylating TaPAP6L to increase endogenous JA content of wheat plants.

Water evaporation is a ubiquitous and spontaneous phase transition process. The utilization of solar‐driven interface water evaporation that simultaneously obtains clean water and power generation can effectively alleviate people's concerns about fresh water and energy shortages. However, it remains a great challenge to efficiently integrate the required functions into the same device to reduce the complexity of the system and alleviate its dependence on solar energy to achieve full‐time operation. In this work, a multifunctional device based on reduced graphene oxide (RGO)/Mn3O4/Al2O3 composite nanomaterials is realized by an asymmetric strategy for effective solar‐thermal‐electro integration that can induce power generation by water evaporation in the presence/absence of light. Under one sun irradiation, the solar‐driven evaporation rate and output voltage are 1.74 kg m−2 h−1 and 0.778 V, respectively. More strikingly, the nine‐grid evaporation/power generation array integrated with multiple devices in series has the advantages of small volume, large evaporation area, and high power generation, and can light up light‐emitting diodes (LEDs), providing the possibility for large‐scale production and application. Based on the high photothermal conversion efficiency and power production capacity of the RGO/Mn3O4/Al2O3 composite evaporation/generator, it will be a promising energy conversion device for future sustainable energy development and applications.

Published: September 2023

Piezoionic materials consisting of a polymer matrix and mobile ions can produce an electrical output upon an applied pressure inducing an ion concentration gradient. Distinct from charges generated by the piezoelectric or triboelectric effects, the use of generated mobile ions to carry a signal closely resembles many ionic biological processes. Due to this similarity to biology, the piezoionic effect has great potential to enable seamless integration with biological systems, which accelerates the advancement of medical devices and personalized medicine. In this review, a comprehensive description of the piezoionic mechanism, methods, and applications are presented, with the aim to facilitate a dialogue among relevant scientific communities. First, the piezoionic effect is briefly introduced, then the development of mechanistic understanding over time is surveyed. Next, different types of piezoionic materials are reviewed and methods to enhance the piezoionic output via materials properties, electrode interfaces, and device architectures are detailed. Finally, applications, challenges, and outlooks are provided. With its novel properties, piezoionics is expected to play a key role in the overcoming of grand challenges in the areas of sensing, biointerfaces, and energy harvesting.

Analog compute‐in‐memory (CIM) systems are promising candidates for deep neural network (DNN) inference acceleration. However, as the use of DNNs expands, protecting user input privacy has become increasingly important. Herein, a potential security vulnerability is identified wherein an adversary can reconstruct the user's private input data from a power side‐channel attack even without knowledge of the stored DNN model. An attack approach using a generative adversarial network is developed to achieve high‐quality data reconstruction from power leakage measurements. The analyses show that the attack methodology is effective in reconstructing user input data from power leakage of the analog CIM accelerator, even at large noise levels and after countermeasures. To demonstrate the efficacy of the proposed approach, an example of CIM inference of U‐Net for brain tumor detection is attacked, and the original magnetic resonance imaging medical images can be successfully reconstructed even at a noise level of 20% standard deviation of the maximum power signal value. This study highlights a potential security vulnerability in emerging analog CIM accelerators and raises awareness of needed safety features to protect user privacy in such systems.
