Multi‐omics and low‐input proteomics profiling reveals dynamic regulation driving pluripotency initiation in early mouse embryos

FEBS Open Bio, Volume 16, Issue 6, Page 1102-1114, June 2026.
Mouse pre‐implantation development involves a transition from totipotency to pluripotency. Integrating transcriptomics, epigenetic profiling, low‐input proteomics and functional assays, we show that eight‐cell embryos retain residual totipotency features, whereas cytoskeletal remodeling regulated by the ubiquitin‐proteasome system drives progression ...

Conceptual Differences Between Hyperspectral Unmixing, PCA, and Clustering: A Practical Demonstration Using Single‐Cell Raman Imaging

Journal of Chemometrics, Volume 40, Issue 6, June 2026.
ABSTRACT Hyperspectral unmixing is a well‐established approach for analyzing spectroscopic images by recovering chemically interpretable component spectra and their spatial distributions. Despite its distinct analytical objective, unmixing is frequently discussed alongside or directly compared with more familiar multivariate techniques such as ...

A PRIMAL-DUAL EXTERIOR POINT ALGORITHM FOR LINEAR PROGRAMMING PROBLEMS

, 2009
The aim of this paper is to present a new simplex type algorithm for the Linear Programming Problem. The Primal- Dual method is a Simplex- type pivoting algorithm that generates two paths in order to converge to the optimal solution.

A Fuzzy Adaptive Simplex Search Optimization Algorithm

, 1999
Most optimization algorithms use empirically-chosen fixed parameters as a part of their search strategy. This paper proposes to replace these fixed parameters by adaptive ones to make the search more responsive to changes in the problem by incorporating ...

Scale‐robust fibre orientation analysis of hair using two‐dimensional Fourier transform

International Journal of Cosmetic Science, Volume 48, Issue 3, Page 539-548, June 2026.
We present a simple and robust method to quantify hair fibre orientation using 2D‐DFT. It works with standard images and extracts directional features at multiple scales. This enables objective evaluation of cosmetic treatments and product effects. Abstract Objective To address the current lack of standardized tools for evaluating hair appearance in ...

SpatialESD: Spatial Ensemble Domain Detection in Spatial Transcriptomics

Advanced Science, Volume 13, Issue 30, 28 May 2026.
ABSTRACT Spatial transcriptomics (ST) measures gene expression while preserving spatial context within tissues. One of the key tasks in ST analysis is spatial domain detection, which remains challenging due to the complex structure of ST data and the varying performance of individual clustering methods. To address this, we propose SpatialESD, a Spatial

ꟻLIP‐Based Perceptual Optimization for Subpixel Rendering Filters

Journal of the Society for Information Display, Volume 34, Issue 5, Page 361-367, May 2026.
We propose a two‐stage subpixel rendering framework combining MMSE‐based initialization and ꟻLIP‐guided perceptual optimization. The kernel is refined by minimizing the mean ꟻLIP error using a Nelder‐Mead optimizer to reduce perceptual distortion beyond RGB‐based methods.
