Strong, Weak and Merging Lines in Atomic Spectra

open access: yesPlasma
We present analytical estimates for the maximum line strength in a transition array, as well as for the numbers of strong and weak lines. For that purpose, two main assumptions are used as concerns the line strength distribution.

Biogeochemical and Hydrological Drivers of Heterogeneous Nutrient Exports From Subterranean Estuaries

open access: yesFrontiers in Marine Science, 2021
Submarine groundwater discharge (SGD) to coastal zones contributes terrestrial freshwater and nutrients that may support harmful algal blooms (HABs).

Detailed opacity calculations for astrophysical applications

open access: yes, 2017
Nowadays, several opacity codes are able to provide data for stellar structure models, but the computed opacities may show significant differences. In this work, we present state-of-the-art precise spectral opacity calculations, illustrated by stellar ...

Doubling your payoff: winning pain relief engages endogenous pain inhibition [PDF]

open access: yes, 2015
When in pain, pain relief is much sought after, particularly for individuals with chronic pain. In analogy to augmentation of the hedonic experience (“liking”) of a reward by the motivation to obtain a reward (“wanting”), the seeking of pain relief in ...

Chronic Pain in Parkinson’s Disease: Prevalence, Sex Differences, Regional Anatomy and Comorbidities

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Chronic pain affected 66.2% of 10,631 individuals with Parkinson's disease, with higher prevalence and severity in females. Pain most often involved the buttocks, lower back, neck, and knees, and was linked to depression, sleep disorders, and osteoarthritis.

Direct reactions for astrophysical p-capture rates with ORRUBA and GODDESS

open access: yesFrontiers in Physics
Understanding the nucleosynthesis and energy generation in quiescent and explosive stellar burning requires a detailed understanding of reaction rates on many unstable nuclides.

Pre‐Diagnostic Features of Multiple Sclerosis in a Diverse UK Cohort: A Nested Case–Control Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Many patients with Multiple Sclerosis (MS) experience nonspecific symptoms prior to diagnosis. This period—the 'MS prodrome'—has been described in socio‐economically homogeneous cohorts to date. It remains unclear to what extent events prior to an MS diagnosis differ according to social determinants of health. Methods We conducted a

Liver organoids in domestic animals: an expected promise for metabolic studies

open access: yesVeterinary Research, 2021
The liver is one of the most important organs, both in terms of the different metabolic processes (energy, lipid, ferric, uric, etc.) and of its central role in the processes of detoxification of substances of food origin or noxious substances (alcohol ...

The effect of some environmental factors on rapid mass movement in the Hunua Ranges, New Zealand [PDF]

open access: yes, 1969
This paper describes some of the relationships between rapid mass movement and environmental factors in the Hunua Ranges. Extreme climatic events appear to be important in triggering mass movement, while vegetation has a marked effect on mass movement ...

Regularities and symmetries in atomic structure and spectra

open access: yes, 2013
The use of statistical methods for the description of complex quantum systems was primarily motivated by the failure of a line-by-line interpretation of atomic spectra. Such methods reveal regularities and trends in the distributions of levels and lines.
