Laryngoscope Investigative Otolaryngology, Volume 11, Issue 5, October 2026.ABSTRACT Background Screening is a critical first step in the early identification and prevention of voice disorders, particularly among at‐risk populations. The Dysphonia Risk Screening Protocol‐General (DRSP‐G) is a comprehensive screening tool that also functions as a standardized patient history; however, no equivalent instrument has previously ...

Advanced Control for Applications, Volume 8, Issue 3, September 2026.Schematic diagram of the whale optimization algorithm (WOA)–optimized fuzzy proportional–integral–derivative (PID) controller. The WOA is employed to dynamically tune the scaling factor expressions and fuzzy control parameters (a(e)a(e), a(ec)a(ec), βpβp, βiβi), as well as the initial PID gains (kp0kp0, ki0ki0), based on the error (ee) and its ...

Advanced Theory and Simulations, Volume 9, Issue 9, September 2026.X2BH6 (X = Li, Na, and K) double perovskite hydrides are investigated using Density Functional Theory (DFT). Highest gravimetric hydrogen storage capacity is found as 19.71 wt % for Li2BH6 and the suitable desorption temperature is found as 308.00 K for K2BH6.

Programmable Flocks: Hierarchical Swarm Control via Dynamic Parameter Injection
Advanced Intelligent Systems, Volume 8, Issue 9, September 2026.We present a method for the control of robot swarms which allows the shaping and the translation of patterns of simple robots (“smart particles”), using two types of devices. These two types represent a hierarchy: a larger group of simple, oblivious robots (which we call the workers) that is governed by simple local attraction forces and a smaller ...
