Lateral ventricular choroid plexus enlargement in patients with spontaneous intracranial hypotension

open access: yesHeadache: The Journal of Head and Face Pain, EarlyView.
Abstract Objective This study aimed to evaluate the choroid plexus volume in patients with spontaneous intracranial hypotension (SIH), including the lateral, third, and fourth ventricles, and explore its potential relationship with clinical characteristics. Background SIH is caused by cerebrospinal fluid (CSF) leaks. The choroid plexus is predominantly

CP-violation in the Weinberg 3HDM potential

open access: yesJournal of High Energy Physics
We explore the phenomenology of Weinberg’s ℤ 2 × ℤ 2 symmetric three-Higgs-doublet potential, allowing for spontaneous violation of CP due to complex vacuum expectation values.

An Uncertainty Based Approach for Dealing With Selection Bias in Non‐Probability Samples

open access: yesInternational Statistical Review, EarlyView.
Summary The main issue with non‐probability samples is that the standard design‐based approach cannot be applied as the selection mechanism is unknown. In this paper, the concept of uncertainty on data generating model, resulting from the lack of knowledge of the sampling design acting in the non‐probability sample, is discussed.

Smart selective navigator (SSN): enhancing urban winter road maintenance through optimized arc routing with hard turn restrictions

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract This paper introduces a novel heuristic method, the smart selective navigator (SSN), for addressing arc routing problems (ARPs) with a focus on integrating hard turn restrictions in urban winter operations. Addressing a significant gap in existing ARP methodologies, SSN seamlessly incorporates common side constraints, such as vehicle ...

Financial Time Series Uncertainty: A Review of Probabilistic AI Applications

open access: yesJournal of Economic Surveys, EarlyView.
ABSTRACT Probabilistic machine learning models offer a distinct advantage over traditional deterministic approaches by quantifying both epistemic uncertainty (stemming from limited data or model knowledge) and aleatoric uncertainty (due to inherent randomness in the data), along with full distributional forecasts.

Admixture Increases Genetic Diversity and Adaptive Potential in Australasian Killer Whales

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Admixture is the exchange of genetic variation between differentiated demes, resulting in ancestry within a population coalescing in multiple ancestral source populations. Low‐latitude killer whales (Orcinus orca) populations typically have higher genetic diversity than those in more densely populated, high productivity and high‐latitude ...
