Fast Mid‐Infrared Spectral Probe Decisions Match H&E Stain Results for Keratinocytic Carcinoma

Journal of Biophotonics, Volume 19, Issue 3, March 2026.
A handheld and fast mid‐infrared fiber‐optic spectral probe is touched to tissue recording a mid‐infrared spectrum that can distinguish keratinocytic cancer from normal skin. ABSTRACT We designed a handheld and fast mid‐infrared fiber‐optic spectral probe using a quantum cascade laser (QCL) and a reduced range of wavelengths, to see if keratinocytic ...

Implicit Third‐Order Peer Triplets with Variable Stepsizes for Gradient‐Based Solutions in Large‐Scale ODE‐Constrained Optimal Control

Optimal Control Applications and Methods, Volume 47, Issue 2, Page 570-588, March/April 2026.
Implicit third‐order Peer two‐step methods that are superconvergent for variable stepsizes have the potential to significantly improve the efficiency of solving large‐scale ODE‐constrained optimal control problems. These include real‐world applications in medical treatment planning for prostate cancer, such as the design of effective three‐dose drug ...

Refined Stratified Random Field Sampling for Inhomogeneous Turbulence Reconstruction

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT We present a refined stratified sampling method for the numerical simulation of a recently introduced random field model for the reconstruction of inhomogeneous turbulence from characteristic flow quantities. The refinement concerns the generation of random wave vectors and allows for an improved accuracy of the simulated fluctuation field.

Improved variable step-size LMS algorithm based on hyperbolic tangent function

Tongxin xuebao, 2020
In order to improve that the LMS algorithm for determining step size cannot satisfy both rapid convergence and low steady-state misalignment errors,a variable step size algorithm (IVSSLMS) based on an improved hyperbolic tangent function was proposed.The

A kind of adaptive variable stepsize embedded Runge–Kutta pairs coupled with the Sinc collocation method for solving the KdV equation

Results in Applied Mathematics
For solving the KdV equation, a novel numerical method with high order accuracy in both space and time is proposed. In the spatial direction, Sinc collocation method, which has the property of exponential convergence, is adopted.

Stability properties of variable stepsize variable formula methods

Numerische Mathematik, 1978
When variable stepsize variable formula methods (VSVFM's) are used in the solution of systems of first order differential equations instability arises sometimes. Therefore it is important to find VSVFM's whose zerostability properties are not affected by the choice of both the stepsize and the formula. The Adams VSVFM's are such methods. In this work a

High‐throughput single‐cell DNA methylation and chromatin accessibility co‐profiling with SpliCOOL‐seq

Clinical and Translational Medicine, Volume 16, Issue 2, February 2026.
SpliCOOL‐seq achieves high‐throughput single‐cell co‐profiling of DNA methylation and chromatin accessibility. DNMT inhibitors caused cancer cell demethylation with divergent patterns. SpliCOOL‐seq enables the discovery of genes related to LUAD tumorigenesis. Ageing and LUAD tumorigenesis may share similar epigenetic alterations.
