Sufficient conditions for three-particle entanglement and their tests in recent experiments [PDF]

, 2001
We point out a loophole problem in some recent experimental claims to produce three-particle entanglement. The problem consists in the question whether mixtures of two-particle entangled states might suffice to explain the experimental data.

Solvent Channels and Electric Fields Guide Proton Delivery to the Active Site of Heme Peroxidases

Angewandte Chemie, Volume 137, Issue 50, December 8, 2025.
Electrostatic potential surfaces and electric field lines reveal that local fields guide proton delivery through multiple conserved solvent channels in heme peroxidases, enabling efficient access to the active site. Abstract The active sites of heme enzymes have evolved to control the formation of highly reactive intermediates in oxidative catalysis ...

Determination of elevated eosinophil to lymphocyte ratio, eosinophil to neutrophil ratio, eosinophil to monocyte ratio and its association with severe vitiligo: A retrospective cohort study.

PLoS ONE
BackgroundHematological markers such as eosinophil-to-lymphocyte (ELR), eosinophil-to-neutrophil (ENR), and eosinophil-to-monocyte (EMR) ratios may be used in the assessment of skin diseases.

Ligand‐Driven Optimization of Iron Oxide Nanoprobes for In Vivo MRI Enhancement at Ultra‐High Field

Small, Volume 22, Issue 16, 17 March 2026.
Ligand‐tailored iron oxide nanoparticles reveal how surface chemistry controls T2 relaxivity and in vivo performance in ultra‐high‐field MRI. Systematic variation of hydrophilicity and charge across five coatings modulated r2 by up to 333 mm−1 s−1, with chemical properties, rather than shell thickness, dictating magnetic dephasing and enabling reliable

Rotational invariance as an additional constraint on local realism

, 2004
Rotational invariance of physical laws is a generally accepted principle. We show that it leads to an additional external constraint on local realistic models of physical phenomena involving measurements of multiparticle spin 1/2 correlations.

New pre-treatment eosinophil-related ratios as prognostic biomarkers for survival outcomes in endometrial cancer

BMC Cancer, 2018
Background Systemic inflammation has long been related with adverse survival outcomes in cancer patients, and its biomarkers, such as the Neutrophil-to-Lymphocyte Ratio (NLR), are recognized as poor prognostic indicators. However, the role of eosinophils

Can Complete Blood Count Inflammation Markers Be Used to Predict Graft Success After Tympanoplasty?

İstanbul Medical Journal, 2020
Introduction:This study aimed to investigate the effect of preoperative neutrophil lymphocyte ratio (NLR), platelet lymphocyte ratio (PLR), eosinophil lymphocyte ratio (ELR), basophil lymphocyte ratio (BLR) and lymphocyte monocyte ratio (LMR) on graft ...

Predicting heat mortality in freshwater communities: temperature and oxygen effects

Ecography, Volume 2026, Issue 2, February 2026.
Freshwater organisms face a dual challenge in warming waters due to increased metabolic demands and declining oxygen levels. However, the relationship between temperature, oxygen, and heat‐induced mortality in natural systems remains poorly understood. Here, we combine heat tolerance measurements in the laboratory with high‐resolution water temperature

Meeting basic needs? Forced migrants and welfare [PDF]

, 2005
As the number of forced migrants entering Britain has risen, increasingly restrictive immigration and asylum policy has been introduced. Simultaneously, successive governments have sought to limit the welfare entitlements of forced migrants. Drawing on
