Piezoelectric Materials in Medical Ultrasound: A Comprehensive Review From Fundamentals to Translational Prospects

open access: yesInformation &Functional Materials, EarlyView.
Piezoelectric materials are reviewed as active platforms for medical ultrasound, bridging electromechanical fundamentals, transducer architectures, and biomedical applications. Material–device co‐design is emphasized as the key to high‐performance diagnosis, therapy, monitoring, wearable ultrasound, and emerging ultrasound‐responsive functions ...

Managing and visualising geochemical data for tephra correlation with the IntChron Integration Tool

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT There is now a wealth of glass‐shard geochemical data for volcanic ash (tephra) layers from a wide range of volcanoes and eruptions, providing invaluable datasets for tephrochronology. However, compilation of published data to assess tephra correlations leads to large files and requires careful management.

Thin‐layer drying kinetics and mathematical modelling of osmotically pretreated vacuum dried green chilli

open access: yesJSFA reports, EarlyView.
Abstract Background Chilli is highly perishable, often requiring drying to extend shelf life. This study assesses and compares the drying kinetics of osmotically pretreated green chilli under vacuum drying conditions while evaluating suitable mathematical models and calculating effective moisture diffusivity and activation energy. Results Sliced chilli

A Reversible Clearing Strategy Enables Robust Label‐Free Phase Imaging of Thick Tissues

open access: yesLaser &Photonics Reviews, EarlyView.
The principle of a reversible clearing strategy via glycerol and tartrazine solution (GTS) for robust whole‐slide label‐free phase imaging of thick tissue slices via high‐throughput Fourier ptychographic microscopy (FPM) and lensless digital holographic microscopy (LDHM). ABSTRACT Thick biological specimens impose strong scattering and attenuation that

Relaxing convergence conditions for Newton's method.

open access: yes, 2000
The classical Kantorovich theorem on Newton's method assumes that the first derivative of the operator involved satisfies a Lipschitz condition 0[F(x)-F(y)]Lx-y. In this paper, we weaken this condition, assuming that 0[F(x)-F(x0)](x-x0) for a given point

A Geometric Interpretation for the Algebraic Properties of Second‐Order Ordinary Differential Equations

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 6, Page 6912-6917, April 2025.
ABSTRACT Nowadays, a substantial portion of investigations concerning the symmetry analysis of differential equations predominantly adhere to a framework comprising the following key procedures: (i) the derivation of symmetries, (ii) the determination of an optimal system, (iii) the utilization of these symmetries to construct invariants or ...

The Price Equation Reveals a Universal Force–Metric–Bias Law of Algorithmic Learning and Natural Selection

open access: yesEntropy
Diverse learning algorithms, optimization methods, and natural selection share a common mathematical structure despite their apparent differences. Here, I show that a simple notational partitioning of change by the Price equation reveals a universal ...
