The role of stress hyperglycemia in in-hospital new-onset atrial fibrillation among patients with acute myocardial infarction: a narrative review

Frontiers in Cardiovascular Medicine
Stress hyperglycemia (SHG) is frequently observed in patients with acute myocardial infarction (AMI). Substantial evidence has established both SHG and the stress hyperglycemia ratio (SHR) as significant, independent predictors of adverse outcomes ...

Decoding THz-Driven Dynamic Fingerprints of Ferroelectric Nanotwin Networks. [PDF]

Adv Mater
ABSTRACT Ultrafast polarization dynamics in ferroelectrics are of considerable interest for high‐speed tunable dielectrics and electro‐optics. Extended domain wall networks formed in ferroelectric twin nanodomains can support collective dynamics in the terahertz regime but require techniques that track polarization and strain evolution driven by ...

Recent Progress in Analytical SHG Spectroscopy

Analytical Sciences, 1998
The progress of laser technology has brought extensive applications of nonlinear optical (NLO) spectroscopy to analytical fields. Especially, optical second harmonic generation (SHG), which is one of the most popular NLO phenomena, has been successfully applied to the study of interfaces (surfaces).

Multimodal two-photon imaging using a second harmonic generation-specific dye

Nature Communications, 2016
Current dyes for second harmonic generation (SHG) imaging strongly fluoresce, limiting their application. Here the authors develop a SHG-specific dye, Ap3, that partitions into cell membranes, displays sensitivity to membrane potential and has virtually ...

Engineering a genetically-encoded SHG chromophore by electrostatic targeting to the membrane

Frontiers in Molecular Neuroscience, 2014
Although second harmonic generation (SHG) microscopy provides unique imaging advantages for voltage imaging and other biological applications, genetically-encoded SHG chromophores remain relatively unexplored.

Quasi-BIC and Reflective Mode Coupling Drives SHG Beyond the Q Factor Limit. [PDF]

Small
An analytical expression is developed to relate second‐harmonic generation to both the resonance Q factor and absorptance. Simulations and experiments on a dual‐resonance 3R‐MoS2 metasurface validate the formula, showing that absorptance engineering provides an effective route to enhance SHG beyond conventional Q‐only design.

When Do Robots Go Green? Unveiling Mechanisms, Thresholds, and Spillovers of Industrial Robotics on Global Ecological Capacity

Business Strategy and the Environment, EarlyView.
ABSTRACT This paper examines the relationship between industrial robotics adoption and ecological capacity, measured by biocapacity, using panel data from 50 countries over the period 2000–2024. We investigate the transmission mechanisms, non‐linearities, spatial spillovers, and heterogeneity characterizing this relationship.
