Soft, Multi‐Wavelength Photoplethysmography Enables Reliable Neonatal Blood Pressure Monitoring Via Error Stratification

open access: yesAdvanced Science, Volume 13, Issue 58, 19 October 2026.
A soft hybrid multi‐wavelength PPG wearable acquires neonatal signals. Synchronized PPG and invasive ABP data are segmented into fixed windows. A 1D‐EfficientNet model predicts segment‐level SBP and DBP. Model performance is examined with retrospective subgroup analysis across acquisition conditions.

Covalent Organic Framework‐Based Optoelectronic Memristors: Structural Design, Optoelectronic Modulation and Neuromorphic Applications

open access: yesAggregate, Volume 7, Issue 10, October 2026.
This review surveys COF‐based optoelectronic memristors from structural design to neuromorphic applications, tracing how framework‐controlled states become history‐dependent conductance. It also identifies the mechanism validation, reproducible film processing and addressable array integration needed for practical visual hardware.

Composition Control in CuInZnS2 Nanocrystals by Cation Exchange and Their Phase Transfer

open access: yesChemNanoMat, Volume 12, Issue 10, October 2026.
This work elucidates the composition‐defining parameters for CuInZnS2 (CIZS) nanocrystals (NCs) prepared by a cation exchange reaction. Investigations focus on their cation shares and size, which influence both the absorbance and the bandgap. Furthermore, a novel ligand exchange route from 1‐dodecanthiol to 11‐mercaptoundecanoic acid is shown, thereby ...

QCD Phenomenology and Light-Front

open access: yes, 2001
A natural calculus for describing the bound-state structure of relativistic compos-ite systems in quantum eld theory is the light-front Fock expansion which encodes the properties of a hadrons in terms of a set of frame-independent n−particle wave ...
