Dizziness in Saudi Arabia: An epidemiologic study
Frontiers in Neurology, 2023 IntroductionDizziness is one of the most common and recurring complaints in adults presenting at the clinic. However, its prevalence in the population of the Kingdom of Saudi Arabia remains unclear.

Clinopyroxene Dissolution Records Rapid Magma Ascent
Frontiers in Earth Science, 2020 Magma ascent rates control volcanic eruption styles. However, the rates at which basaltic magmas ascend through the crust remain highly uncertain. Although recent studies have successfully exploited records of decompression driven degassing to estimate ...

Disequilibrium in behavior analysis: A disequilibrium theory redux
Behavioural Processes, 2019 Disequilibrium theory is an approach to reinforcement that reconsiders the putative response strengthening prowess of stimuli. This disequilibrium approach-the pinnacle of the response deprivation hypothesis-reliably predicts changes in behavior without reference to a response strengthening process.

Disequilibrium Mapping: Composite Likelihood for Pairwise Disequilibrium
Genomics, 1996 The pattern of linkage disequilibrium between a disease locus and a set of marker loci has been shown to be a useful tool for geneticists searching for disease genes. Several methods have been advanced to utilize the pairwise disequilibrium between the disease locus and each of a set of marker loci.

Monnaie, crédit et inflation : l’analyse de Le Bourva revisitée
Œconomia, 2020 Monetary theory that has become dominant from the 1970 onwards is based on two main proposals: Inflation is the consequence of the excess money supply issued by a central bank obliged to follow the will of impecunious governments, and the amount of money

On detecting biospheres from chemical thermodynamic disequilibrium in planetary atmospheres [PDF]
Astrobiology, Volume 16, Number 1, 2016, 2015 Atmospheric chemical disequilibrium has been proposed as a method for detecting extraterrestrial biospheres from exoplanet observations. Chemical disequilibrium is potentially a generalized biosignature since it makes no assumptions about particular biogenic gases or metabolisms.

Linkage disequilibrium under recurrent bottlenecks [PDF]
Genetics 190, 217 (2012), 2011 Understanding patterns of selectively neutral genetic variation is essential in order to model deviations from neutrality, caused for example by different forms of selection. Best understood is neutral genetic variation at a single locus, but additional insights can be gained by investigating genetic variation at multiple loci.

Disequilibrium biosignatures over Earth history and implications for detecting exoplanet life [PDF]
Science Advances 24 Jan 2018: Vol. 4, no. 1, eaao5747, 2018 Chemical disequilibrium in planetary atmospheres has been proposed as a generalized method for detecting life on exoplanets through remote spectroscopy. Among solar system planets with substantial atmospheres, the modern Earth has the largest thermodynamic chemical disequilibrium due to the presence of life.
