The Role of Opacities in Stellar Pulsation [PDF]
, 2018 We examine the role of opacities in stellar pulsation with reference to Cepheids and RR Lyraes, and examine the effect of augmented opacities on the theoretical pulsation light curves in key temperature ranges.

FEBS Open Bio, EarlyView.Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Refractile superficial retinal crystals and chronic retinal detachment: Case report
BMC Ophthalmology, 2006 Background Few previous reports have described the presence of retinal refractile opacities at the macular area in patients presenting with longstanding peripheral retinal detachment. The exact nature of these opacities is unknown.

Computation of atomic astrophysical opacities
, 2018 The revision of the standard Los Alamos opacities in the 1980-1990s by a group from the Lawrence Livermore National Laboratory (OPAL) and the Opacity Project (OP) consortium was an early example of collaborative big-data science, leading to reliable data

Aging and Cancer, EarlyView.This systematic review synthesizes prognostic models for survival and recurrence in resected non‐small cell lung cancer. While many models demonstrate moderate to good discrimination, few are externally validated and reporting quality is variable, limiting clinical applicability and highlighting the need for robust, transparent model development ...

Acta Stomatologica Croatica, 2020 Objectives: Demarcated opacities (DO) on teeth affected by Molar Incisor Hypomineralisation (MIH) were observed to investigate if parameters of DO existence and the number of teeth affected could be used to predict the progression of disease.

The Relationship between IGM Lyα Opacity and Galaxy Density near the End of Reionization
The Astrophysical Journal, 2023 Observed scatter in the Ly α opacity of quasar sightlines at z < 6 has motivated measurements of the correlation between Ly α opacity and galaxy density, as models that predict this scatter make strong and sometimes opposite predictions for how they ...
