Addressing disorientation in endoscopy: A study on mental rotation difficulty and its impact on cognitive load measured by pupillary response

Laparoscopic, Endoscopic and Robotic Surgery
Objectives: One of the most notable challenges in endoscopic procedures is maintaining correct orientation. Mental rotation exercise (MRE) has been suggested as a potential aid for improving orientation.

Experimental and Modeling Investigation of Seawater Hydrolysis Effects on Aramid Fiber Rupture Behavior

Journal of Polymer Science, EarlyView.
Hydrolytic aging in seawater produces markedly different mechanical responses among commercial Aramid fibers. While some fibers exhibit progressive degradation, others maintain stable or even improved tensile behavior. Experimental yarn‐scale testing combined with mathematical degradation modeling and Arrhenius‐based lifetime prediction provides new ...

Exploiting Device Deformability for Fluid and Particle Manipulation

Small, EarlyView.
Deformable devices enable fluid and particle manipulation modes that are inaccessible to rigid platforms. This review examines soft materials and architectures that translate controlled deformation into microscale fluid operations such as pumping, valving, mixing, and particle handling.

Counting the Uncountable: Measuring the Benefits of MRE [PDF]

, 2015
The aim of this article is to propose concepts that define MRE in terms of its outcomes and beneficiaries and to open a discussion on developing a means that may then be useful in measuring the efficacy of MRE.

Phase‐inversion constructed Mo2C@NC microreactor with optimized pyridinic N p‐band center for high‐performance Li–S batteries

Smart Molecules, EarlyView.
A phase‐inversion constructed Mo2C@NC microreactor activates the intrinsic catalysis of nitrogen‐doped carbon via interfacial electron redistribution. Strong charge transfer to pyridinic N optimizes the p‐band center, enabling efficient lithium polysulfide adsorption, fast redox kinetics, and long‐term stable, high‐rate Li–S battery performance ...

Synergistic and Antagonistic Effects of Chemical Pollutants and Parasitic Fungi on Cyanobacterial Metabolism

Environmental Toxicology, EarlyView.
ABSTRACT Freshwater ecosystems are increasingly impacted by anthropogenic pollutants, including the widely used herbicide metolachlor (MET) and cigarette butt (CB) litter. Parasites represent an additional biotic stressor that can modulate pollutant effects on their hosts.

APTNet: A Condition‐Sensitive Modulation Framework for Surface Pressure Prediction on Supersonic Aircraft

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Accurate surface‐pressure prediction over broad operating envelopes is critical for supersonic aerodynamic analysis and design. To overcome the bottlenecks of traditional computational fluid dynamics (CFD) in real‐time performance and computational efficiency, data‐driven deep learning methods have emerged. However, existing data‐driven models
