This paper presents a theoretical investigation of the plasmon excitation spectrum in monolayer silicene systems at finite temperatures under the random-phase approximation. Because of silicene's buckled honeycomb structure and strong spin–orbit coupling (△so), its bandgap can be tuned electrically via an external perpendicular field that induces a sublattice potential difference (△z). This study examines how […]

Background: Atrial fibrillation (AF) is a leading cause of ischemic stroke, often underdiagnosed in acute settings. Objective: To determine the prevalence of AF in hospitalized ischemic stroke patients and analyze associated clinical characteristics. Methods: A prospective cross-sectional study was conducted on 99 patients with acute ischemic stroke admitted to Thong Nhat Hospital from January 2024 […]

Mg2Sn-based semiconductors are promising candidates for electrical and thermoelectric device applications. Mg2Sn is a narrow-bandgap semiconductor; however, its thin-film forms have not been extensively studied. In this study, Mg2Sn films were deposited on glass substrates by co-sputtering with a fixed RF source for the Mg target and varying the DC sputtering power for the Sn […]

In the Anthropocene context of water pollution by industrial chemicals and microplastics, the sustainable development of inexpensive, energy-saving, and biodegradable water purification membrane technologies is the urgent need for environmental remediation. While biodegradable cellulose filter papers are popular, cost-effective, and eco-friendly membrane materials, their large porous structure requires functional enhancement for effective microfiltration. Herein, we […]

This paper investigates the Vietnamization and Huế-localization of female deities of Cham and Chi- nese origin in Huế through belief legends, focusing on two cases: Thiên Y A Na (adapted from the Champa and Cham goddess Yang Po Ina Nagar and Po Inâ Nâger) and Thiên Hậu Thánh Mẫu (adapted from the Chinese sea goddess […]

Gamma transmission is a prominent technique for performing nondestructive testing and material analysis, particularly high-precision thickness measurements. However, its accuracy is often compromised by small-angle scattering, in which photons deflected at shallow angles are incorrectly counted by the detector as part of the primary transmitted beam. This is especially pronounced when using common low-resolution scintillation […]

This study proposes an enhanced localization and mapping algorithm for indoor mobile robots based on Ultra-Wideband (UWB) technology. By integrating UWB with odometry and LiDAR sen- sors through an Extended Kalman Filter (EKF), the developed approach addresses the limitations of conventional Simultaneous Localization and Mapping (SLAM) techniques in warehouse envi- ronments. Whereas conventional SLAM methods […]

This research explored the role of casing material selection in shaping the formation process and terminal performance of explosively formed projectiles (EFP). Six casing types, including polymer materials, aluminum alloys, and structural steels, were analyzed using numerical simulation and experimental testing in identical warhead configurations. The results of numerical simulations conducted in Ansys Autodyn with […]
