Attitude and Involvement Regarding Sexual and Reproductive Health Among University Students: A Cross‐Sectional Study in Bangladesh

Health Science Reports, Volume 9, Issue 3, March 2026.
ABSTRACT Background and Aims Sexual and reproductive health (SRH) is a crucial aspect of overall health and well‐being, especially among young adults. However, in many low‐ and middle‐income countries, including Bangladesh, SRH issues remain underexplored due to sociocultural taboos, stigma, and inadequate education.

Al Nanoparticle‐Decorated Metal Oxide Synaptic Transistors for Ultralow‐Energy Neuromorphic Computing with Wide Dynamic Range

Advanced Science, Volume 13, Issue 9, 13 February 2026.
A nanoparticle‐engineered electrolyte‐gated memtransistor is introduced as a materials‐level strategy to overcome the intrinsic trade‐off between energy consumption and synaptic precision. By embedding aluminum nanoparticles at the oxide–electrolyte interface to modulate ion trapping dynamics, the device achieves stable multistate plasticity under ...

Optimal Placement of PMU for Power System Observability

International Journal of Advanced Research in Electrical, Electronics and Instrumentation Engineering, 2014
Phasor Measurement Unit (PMU) is a relatively new technology that, when employed in power networks, offers real-time synchronised measurements of the voltages at buses and currents along the lines that connect them. This is accomplished by using a GPS based monitoring system which facilitates time synchronisation of measurements and unlike SCADA, makes
