Computational Fluid Dynamics Analysis into the Comparison of Resistance Characteristics Between DARPA Suboff and Modified U209 Types of Submarines

Sci
Submarines are required to have good performance, which is influenced by their type of hull, hull conditions, and operational conditions. This study compares the resistance between a Modified-U209 (U209) submarine and the DARPA Suboff.

The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review

Journal of Field Robotics, Volume 43, Issue 6, Page 4094-4115, September 2026.
ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...

Grafted Low‐Leakage Si/AlN p‐n Diodes Enabled by Fluorinated AlN Interface

Advanced Materials Interfaces, Volume 13, Issue 16, 18 August 2026.
This work demonstrates a fluorination‐based interface engineering strategy that transforms oxygen‐terminated AlN surfaces into fluorine‐terminated interfaces for grafted p‐Si/n‐AlN diodes. By combining pseudo‐ALE oxide removal, XeF2 fluorination, and ultrathin SiNx stabilization, the engineered interface suppresses defect‐assisted reverse leakage by ...

In‐Memory Continuous‐Time SAT Solver Based on Bidirectional 11‐T SRAM Macro

Advanced Intelligent Systems, Volume 8, Issue 8, August 2026.
This article reported a continuous‐time (CT) Boolean satisfiability (SAT) problem solver using bidirectional 11T‐SRAM macro. The proposed system operates asynchronously using capacitor‐based gradient integration and maximizes the parallelism for SAT solving by in‐memory computing (IMC).

Spatial variability of hydrodynamics in oyster reefs: Investigating the impact of canopy density on mean and turbulent flows

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract This field study investigated how oyster canopy density modulates hydrodynamics of natural intertidal oyster reef. High‐resolution velocity measurements were taken simultaneously within and above oyster canopies of variable density (solid volume fractions, Ø=$$ \mathrm{\O}= $$ 0.04–0.21).
