Ground‐ and Excited‐State Mixed Valency in a 4,4′‐Bipyridine‐Bridged Bimetallic Di‐Ruthenium Complex

European Journal of Inorganic Chemistry, Volume 29, Issue 16, 4 June 2026.
Photoinduced mixed‐valence interactions across a 4,4′‐bpy bridge were studied. MLCT excited states in the bimetallic complex are longer‐lived than in the monometallic reference, thanks to metal–metal electronic coupling and hole delocalization, but are still shorter than the nanosecond timescale relevant for diffusional reactivity.

Teach AI What It Doesn't Know

AI Magazine, Volume 47, Issue 2, Summer 2026.
Abstract AI systems are rapidly transitioning from laboratory demonstrations to decision‐making technologies deployed in high‐stakes domains. Yet reliability remains a primary obstacle to responsible adoption: discriminative models can be confidently wrong under out‐of‐distribution (OOD) inputs, and foundation models (FMs) such as large language models

PCA‐based respiratory motion modeling for individualized PTV margin optimization in NSCLC radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 6, June 2026.
Abstract Background Respiratory motion remains a major challenge in radiotherapy for non‐small cell lung cancer (NSCLC), often requiring a balance between target coverage and normal tissue sparing. Introduction This study aimed to develop and validate a clinically implementable, individualized PTV margin strategy by integrating principal component ...

Structural Eigenmodes of the Brain to Improve the Source Localization of EEG: Application to Epileptiform Activity

Advanced Science, Volume 13, Issue 31, 4 June 2026.
Geometry and connectivity are complementary structures, which have demonstrated their ability to represent the brain's functional activity. This study evaluates geometric and connectome eigenmodes as biologically informed constraints for EEG source localization.

Collaborative Optimization of Charge Carrier Dynamics and Energy Loss of Organic Solar Cells via Rational Morphology Regulation

Aggregate, Volume 7, Issue 6, June 2026.
This work systematically investigates the effects of 3‐phenylthiophene (TPh), biphenyl (BPh), and 1‐chloro‐4‐iodobenzene (CIB) additive treatments on photoactive layer morphology. Among them, BPh synergistically enhances charge dynamics and significantly reduces energy loss, enabling simultaneous improvements in photocurrent and voltage and thus ...

Operationalizing diffusion magnetic resonance imaging positivity for detection of vascular contributions to impairment and dementia

Alzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION White matter lesions on fluid‐attenuated inversion recovery magnetic resonance imaging (FLAIR‐MRI) reflect small vessel disease (SVD) and aid in identifying vascular contributions to impairment and dementia (VCID). Emerging diffusion MRI (dMRI) biomarkers are sensitive to early SVD but the lack of validated approaches for defining

Differential associations of plasma biomarkers with Alzheimer's disease and small vessel disease: A multimodal imaging study

Alzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION We investigated how plasma biomarkers (phosphorylated tau 217 [ptau217], glial fibrillary acidic protein [GFAP], neurofilament light chain [NfL]) relate to imaging markers of small vessel disease (SVD) and Alzheimer's disease (AD), and cognition in memory clinic patients.

Association of imaging‐defined brain age with disease severity and adverse outcomes in CADASIL

Alzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is caused by cysteine‐altering NOTCH3 variants. We examined whether neuroimaging‐defined brain age is altered in CADASIL and its association with disease severity and outcomes.

Cognitive reserve against vascular contributions to cognitive impairment and dementia: A scoping review

Alzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract Vascular contributions to cognitive impairment and dementia (VCID) are common in older adults and are typically associated with cerebral small vessel disease (cSVD). However, little remains known about non‐pharmacological, modifiable lifestyle variables that may build cognitive reserve against cSVD/VCID.

Cerebral small vessel disease and cognition in older adults across the neurodegenerative spectrum: insights from the COMPASS‐ND study

Alzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION Imaging‐based cerebral small vessel disease (CSVD) summary scores quantify CSVD burden. This study characterized CSVD scores and assessed their cognitive associations in older adults with various neurodegenerative diseases and cognitive profiles.
