Brain dopamine receptor system is not altered in obesity: Bayesian and frequentist meta-analyses. [PDF]
Hum Brain Mapp, 2023 Brain dopamine receptor availability is not different between lean and overweight/obese subjects according to both Bayesian and frequentist meta‐analyses. However, the effect is dependent on the radiopharmaceutical and the degree of obesity. Abstract Feeding induces dopamine release in the striatum, and a dysfunction of the dopaminergic reward system ...

Family Income Is Associated With Regional Brain Glucose Metabolism in Middle-Aged Males. [PDF]
Eur J NeurosciABSTRACT Socioeconomic status is a multifaceted construct that plays a prominent role in shaping our environment. This study investigated the associations between family income, education level, and brain glucose metabolism in middle‐aged males. We retrospectively analysed data of healthy males who underwent a health check‐up programme including (1 ...

Personalized Nutrition Recommendations Using a Bayesian Mixture Model of Concentration Constraints and Intake Preferences. [PDF]
Stat MedABSTRACT Maintaining proper nutrition is crucial for preserving health and preventing disease. However, what constitutes proper nutrition may vary among individuals; evidence indicates that the effects of diet and even single nutrients can differ considerably because of personal characteristics.

Modeling basal body temperature data using horseshoe process regression. [PDF]
Stat MedBiomedical data often exhibit jumps or abrupt changes. For example, women's basal body temperature may jump at ovulation, menstruation, implantation, and miscarriage. These sudden changes make these data challenging to model: many methods will oversmooth the sharp changes or overfit in response to measurement error.

Effects of the timing of grazing on insect diversity and insect-plant interactions in mountain grasslands. [PDF]
Ecol ApplAbstract Grazing is the common agricultural land‐use in mountain regions. It is of high socioeconomic importance but also essential for conservation as extensive mountain pastures are hotspots of biodiversity. Climate change is causing earlier growing seasons, prompting earlier livestock turnout.

Parameterized Algorithms for MILPs with Small Treedepth
Proceedings of the AAAI Conference on Artificial Intelligence, 2021 Solving (mixed) integer (linear) programs, (M)I(L)Ps for short, is a fundamental optimisation task with a wide range of applications in artificial intelligence and computer science in general. While hard in general, recent years have brought about vast progress for solving structurally restricted, (non-mixed) ILPs: n-fold, tree-fold, 2-stage stochastic

A polynomial excluded-minor approximation of treedepth [PDF]
Journal of the European Mathematical Society, 2018 Treedepth is a minor-monotone graph invariant in the family of “width measures” that includes treewidth and pathwidth. The characterization and approximation of these invariants in terms of excluded minors has been a topic of interest in the study of sparse graphs.

Computing treedepth in polynomial space and linear fpt time
CoRR, 2022 The treedepth of a graph $G$ is the least possible depth of an elimination forest of $G$: a rooted forest on the same vertex set where every pair of vertices adjacent in $G$ is bound by the ancestor/descendant relation. We propose an algorithm that given a graph $G$ and an integer $d$, either finds an elimination forest of $G$ of depth at most $d$ or ...

European Journal of Neuroscience, Volume 55, Issue 2, Page 405-425, January 2022., 2022 We used multi‐site transcranial alternating stimulation at theta frequency to either synchronize or desynchronize a fronto‐parietal working memory network in order to modulate verbal working memory performance. Results indicate that a behavioural modulatory effect of synchronizing fronto‐parietal tACS can only be observed in a working memory task of ...

Integer Programming and Incidence Treedepth [PDF]
, 2019 Recently a strong connection has been shown between the tractability of integer programming (IP) with bounded coefficients on the one side and the structure of its constraint matrix on the other side. To that end, integer linear programming is fixed-parameter tractable with respect to the primal (or dual) treedepth of the Gaifman graph of its ...
