Low-temperature synthesis is crucial for advancing sustainable manufacturing and accessing novel metastable phases. Metal hydrides have shown great potential in facilitating the reduction of oxides at low temperatures, yet underlying mechanism─whether driven by H–, H2, or atomic H─remains unclear. In this study, we employ situ electrical transport measurements first-principles calculations to investigate CaH2-driven kinetics epitaxial α-Fe2O3 thin films. Intriguingly, samples direct contact...

We propose an analytical thermodynamic model for describing defect phase transformations, which we term the statistical evaluation approach (SPEA). The SPEA assumes a Boltzmann distribution of finite-size fractions and calculates their average. To benchmark performance model, apply it to construct binary surface diagrams metal alloys. Two alloy systems are considered: Mg with Ca substitutions Ni Nb substitutions. firm basis against can be leveled, first perform Monte Carlo (MC) simulations...

Existing multimodal-based human action recognition approaches are either computationally expensive, which limits their applicability in real-time scenarios, or fail to exploit the spatial temporal information of multiple data modalities. In this work, we present an efficient pose-driven attention-guided multimodal network (EPAM-Net) for videos. Specifically, adapted X3D networks both RGB and pose streams capture spatio-temporal features from videos skeleton sequences. Then utilized help...

Alternative cements, such as alkali-activated materials (AAMs), produced from the alkaline activation of industrial byproducts, represent a potential lower-CO2 substitute for ordinary Portland cement (OPC). However, interaction main binder phases, calcium-silicate-hydrate-type gels, with corrosive ions surrounding environment remains largely unexamined. This is particularly case gels that contain alkalis, sodium, which exist in OPC blended recycled sodium-rich glass and high-Ca AAMs. In this...

Providing the hospitality and tourism higher education in past four decades witnessed fast growth. Provision of this highly recommended to be integrated as possible with real practice industry. Active Learning is observed an educational atmosphere where students become dynamically engaged compared passively absorbing while taught by teachers. Practical skills development has been recognized a clear focus F&B teaching constitutes essentiality graduates. The aim research assess applicability...

تعتبر المساجد التقليدية أحد الأفرع الهامة للعمارة (1) ، وتزخر المملکة العربية السعودية بالعديد من هذا النوع المساجد. وقد وضح ابن خلدون الفارق بين المسجد التقليدي والمسجد ذو الطراز : اعلم أن صنفان مساجد عظيمة کثيرة الـغاشية معدة للصلوات المشهورة وأخرى دونها مختصة بقوم أو محلة وليست العامة ؛ فأما العظيمة فأمرها راجع إلى الخليفة يفوض إليه سلطان وزير قاض فينصب بها الإمام في الصلوات الخمس والجمعة والعيدين والخسوفين والاستسقاء وتعيين ذلک إنما هو طريق الأولى والاستحسان ثم شاع استخدام لفظ الجامع...

In this paper, we propose a novel technique for measuring behavioral engagement through students' actions recognition. The proposed approach recognizes student then predicts the level. For action recognition, use human skeletons to model postures and upper body movements. To learn dynamics of body, 3D-CNN is used. trained used recognize within every 2minute video segment these are build histogram which encodes their frequencies. This utilized as an input SVM classifier classify whether...
