AXION-DE SITTER WORMHOLES

Axion-de Sitter wormholes

Abstract We construct wormholes supported by axion flux in the presence of a positive cosmological constant.The solutions describe compact, one-handle bodies colloquially known as kettlebell geometries.The wormholes are perturbatively stable, but regularity of the Euclidean geometry implies an upper bound on the axion flux.Viewed as no-boundary sad

Oxidative and Excitatory Neurotoxic Stresses in CRISPR/Cas9-Induced Kynurenine Aminotransferase Knockout Mice: A Novel Model for Despair-Based Depression and Post-Traumatic Stress Disorder

Backgrounds: Memory and emotion are especially vulnerable to psychiatric disorders such as post-traumatic stress disorder (PTSD), which is linked to disruptions in serotonin (5-HT) metabolism.Over 90% of the 5-HT precursor tryptophan (Trp) is metabolized via the Trp-kynurenine (KYN) metabolic pathway, which generates a variety of bioactive molecule

Smooth ROC curve estimation via Bernstein polynomials.

The receiver operating characteristic (ROC) curve is commonly used to evaluate the accuracy of a diagnostic test for classifying observations into two groups.We propose two novel tuning parameters for estimating the ROC curve via Bernstein polynomial smoothing of the empirical mr robot funko ROC curve.The new estimator is very easy to implement wit
