A flexible dual‐gate thin‐film transistor‐based tactile sensor array with polarity‐aware encoding for neuromorphic recognition

FlexMat, EarlyView.
A flexible piezoelectric tactile sensor array is developed by integrating polyvinylidene fluoride sensing elements with dual‐gate indium‐tin‐zinc oxide thin‐film transistor‐based pixel amplifiers. Direct coupling to the high‐impedance gate minimizes signal loss, enabling twofold voltage amplification and an extended effective relaxation time of ∼4.86 s

Sonographic localisation of lymph nodes suspicious of metastatic breast cancer to surgical axillary levels

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 119-138, March 2025.
Sonographic imaging is used to identify the presence, number and location of malignant lymph nodes. Axillary lymph nodes suspicious of harbouring breast cancer metastasis can be localised to three surgical axillary levels. This paper will unpack the axillary anatomy, muscular sonographic landmarks, surgical axillary lymph node levels and the ...

Estimating a convex function in nonparametric regression [PDF]

A new nonparametric estimate of a convex regression function is proposed and its stochastic properties are studied. The method starts with an unconstrained estimate of the derivative of the regression function, which is firstly isotonized and then ...

Defining sagittal knee phenotypes via monopedal static anterior tibial translation. Part 1: Translating weight‐bearing sagittal position into clinical risk profiles

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Static anterior tibial translation (sATT) is a reproducible monopodal weight‐bearing radiographic parameter that reflects the resting sagittal position of the tibiofemoral joint. Distinct from manual laxity tests that quantify passive displacement limits, sATT captures the functional equilibrium of the tibia under physiological load ...

Morphological Similarity Between Edo‐Period Wooden Dentures and Maxillae in Japan: A Three‐Dimensional Analysis Using Homologous Modeling

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Wooden dentures represent a distinctive form of dental technology uniquely developed in Japan that is no longer in clinical use. Although Edo‐period (1603–1867) wooden dentures are presumed to have achieved sufficient precision, their morphological fit has not been quantitatively evaluated.

A Method For Approximating Univariate Convex Functions Using Only Function Value Evaluations [PDF]

In this paper, piecewise linear upper and lower bounds for univariate convex functions are derived that are only based on function value information. These upper and lower bounds can be used to approximate univariate convex functions.

An Ergonomic Customizable Soft Robotic Glove Toward Personalized Hand Rehabilitation

SmartBot, EarlyView.
Soft robotic gloves for hand rehabilitation are often limited by poor fit and uneven pressure on the fingers. Here, the authors report an ergonomic all‐fabric glove whose dual‐action actuators are tailored to individual finger geometry by CNC heat sealing, with symmetrical chambers that distribute interface pressure more evenly. Weighing only 90 g, the
