CFD modeling and sensitivity‐guided design of silicon filament CVD reactors
AIChE Journal, EarlyView.Abstract Filament‐based chemical vapor deposition (CVD) for silicon (Si) coatings is often treated as an adaptation of planar deposition. But this overlooks fundamental shifts in transport phenomena and reaction kinetics. In filament CVD, the filament acts as a substrate, heat source, and flow disruptor simultaneously. In this work, we ask: What really

Advanced Intelligent Discovery, EarlyView.In this study we employed support vector regressor and quantum support vector regressor to predict the hydrogen storage capacity of metal–organic frameworks using structural and physicochemical descriptors. This study presents a comparative analysis of classical support vector regression (SVR) and quantum support vector regression (QSVR) in predicting ...

Vision‐Based Handover and Organization of Robotic Scrub Nurse for Seamless Surgical Flow
Advanced Intelligent Systems, EarlyView.This study presents a pose estimation‐based robotic scrub nurse (PERSN) that assists surgical procedures by estimating the surgeon's hand position, orientation, and grasping state, along with the constraint‐based 6D pose of surgical instruments. User evaluations show that PERSN provides greater immediate usability and reduces physical demand compared ...

Miniaturized Conductometric Biosensor for Rapid Detection of TNF‐α in Saliva
Advanced NanoBiomed Research, EarlyView.A miniaturized conductometric sensor detects TNF‐α at femtomolar levels with high selectivity. The device enables noninvasive testing using pooled human saliva and supports smartphone‐based, real‐time resistance readings. This portable biosensor offers a practical alternative for monitoring TNF‐α, providing new opportunities for diabetes and related ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Liquid hydrogen, a zero‐carbon and high–energy‐density fuel, is a promising option for future oceangoing vessels. During maritime transportation, onboard cryogenic tanks are exposed to ambient heat leakage and ship‐induced roll motion, which can trigger sloshing and fundamentally modify the coupled thermo‐fluid processes governing boil‐off and

Archaeological Prospection, EarlyView.ABSTRACT Burial mounds are key elements of Mediterranean funerary landscapes, but in intensively cultivated coastal plains their low‐relief expression is easily obscured by ploughing, levelling and rapidly changing surface conditions, making single‐date observations unreliable.
