XHEMTs on Ultrawide Bandgap Single‐Crystal AlN Substrates

open access: yesAdvanced Electronic Materials, EarlyView.
AlN/GaN/AlN XHEMTs [single‐crystal (“X‐tal”) high‐electron‐mobility transistors] are built on bulk AlN substrates with a 20 nm pseudomorphic GaN channel. This coherent epitaxial double heterostructure promises low‐defect, thermally efficient nitride electronics for next‐generation RF technology.

Highly Active IrRuOx/MnOx Electrocatalysts with Ultralow Anode PGM Demand in Proton Exchange Membrane Electrolyzers

open access: yesAdvanced Energy Materials, EarlyView.
MnOx‐supported IrRuOx exhibits outstanding OER performance in both liquid electrolytes and real cell environments. The MnOx not only enhances the dispersion of IrRuOx but also induces a compressive strain effect. The incorporation of Ru leads to surface reconstruction.

Advances in the Management and Surgical Treatment of Intracranial Aneurysms [PDF]

open access: yes, 1974
Patients who have sustained a spontaneous subarachnoid hemorrhage are victims of a very serious illness. Not only are they subject at all times to the potentially catastrophic results of a recurrent bleed, but they are faced with the manifestations of ...

Inverse Design of Alloys via Generative Algorithms: Optimization and Diffusion within Learned Latent Space

open access: yesAdvanced Intelligent Discovery, EarlyView.
This work presents a novel generative artificial intelligence (AI) framework for inverse alloy design through operations (optimization and diffusion) within learned compact latent space from variational autoencoder (VAE). The proposed work addresses challenges of limited data, nonuniqueness solutions, and high‐dimensional spaces.

Symptomatic Unilateral Subdural Effusion as the First Presentation of Suprasellar Arachnoid Cyst

open access: yesIranian Journal of Neurosurgery, 2017
Background and Importance: Arachnoid cysts are benign nontumoral lesions that are usually found incidentally in brain imaging. Suprasellar Arachnoid Cysts (SSACs) are rare.

Crater Observing Bioinspired Rolling Articulator (COBRA)

open access: yesAdvanced Intelligent Systems, EarlyView.
Crater Observing Bio‐inspired Rolling Articulator (COBRA) is a modular, snake‐inspired robot that addresses the mobility challenges of extraterrestrial exploration sites such as Shackleton Crater. Incorporating snake‐like gaits and tumbling locomotion, COBRA navigates both uneven surfaces and steep crater walls.

Planning and Control Framework for a Quadruped Robot With Changeable Configuration

open access: yesAdvanced Intelligent Systems, EarlyView.
Multiconfiguration quadruped robots enhance adaptability by switching between mammal‐like and reptile‐like morphologies. This study presents a nonlinear constraint‐based motion planner integrated with a hierarchical whole‐body controller, enabling robust configuration switching and locomotion on complex terrains. Experiments on slopes, irregular bricks,
