Enhanced Gas-Flow-Induced Voltage in Graphene

, 2011
We show by systemically experimental investigation that gas-flow-induced voltage in monolayer graphene is more than twenty times of that in bulk graphite. Examination over samples with sheet resistances ranging from 307 to 1600 {\Omega}/sq shows that the

Non-linear analysis of two-layer timber beams considering interlayer slip and uplift [PDF]

, 2010
A new mathematical model and its finite element formulation for the non-linear analysis of mechanical behaviour of a two-layer timber planar beam is presented. A modified principle of virtual work is employed in formulating the finite element method. The

Formal and non-formal approaches to the notion of "Risk" : a historical perspective [PDF]

, 2008
The paper will focus on the early texts of Galileo Galilei (1613~1623) and Daniel Bernoulli (1738) as examples of pure combinatorical analysis and perspectively considerations within the mathematical discipline of probability theory.

Effect of a surface shear layer on gravity and gravity–capillary waves of permanent form [PDF]

, 1990
Calculations are carried out of the shape of gravity and gravity–capillary waves on deep water in the presence of a thin sheet of uniform vorticity which models the effect of a wind drift layer.

A High‐Durability Triboelectric Nanogenerator for Broad‐Spectrum Wind Energy Harvesting

Advanced Materials Interfaces, EarlyView.
This study presents an easy‐starting and high‐durability triboelectric nanogenerator (ESHD‐TENG) for efficient broad‐spectrum wind energy harvesting. By integrating a fan blade design and a mode‐switching mechanism, the device achieves a low cut‐in wind speed of 0.9 m −1s and significantly enhanced durability, addressing key challenges in current TENG ...

UltRAP‐Net: Reverse Approximation of Tissue Properties in Ultrasound Imaging

Advanced Intelligent Systems, EarlyView.
This study proposes a reverse approximation neural network (UltRAP‐Net) to extract underlying physics‐aware properties using multiple images with distinct appearances obtained at the same location of tissues. Through this robust approximation, the study advances the use of ultrasound images by opening potentials for various applications such as physics‐

RefineCatDiff: Toward High‐Quality Medical Image Segmentation via a Categorical Diffusion Refinement Framework

Advanced Intelligent Systems, EarlyView.
This study proposes RefineCatDiff, a refinement framework for high‐quality medical image segmentation. By developing a categorical distribution‐based discrete diffusion process for refinement, the framework aligns well with the characteristics of image segmentation tasks. Experimental results on multiple datasets across different modalities demonstrate

Quantifying Imperfect Cognition Via Achieved Information Gain

Annalen der Physik, EarlyView.
Cognition, the processing of information in the form of inference, communication, and memorization, is the central activity of any intelligence. To quantify imperfect cognition, the concept of achieved information gain (AIG) is introduced. AIG can be derived axiomatically, allows cognitive fidelity and efficiency to be defined mathematically, and ...
