Massive spinning particles acquire helicity-dependent chemical potentials during the inflation from axion-type couplings. Such fields can mediate sizable inflaton correlators which we call helical correlators. Helical are approximately scale invariant, dS boost breaking, parity-violating, and promising observables of cosmological collider physics. In this work, present complete analytical resul...

In this paper, we present several potentially useful properties of the Barnes G-function. The considered here include, for example, its integral representation, complete monotonicity, and continued-fraction approximation. We also derive approximations Glaisher-Kinkelin constant Choi-Srivastava constants.

We present a performance comparison of tree data structures for N -body simulation. The tree data structures examined are the balanced binary tree and the Barnes– Hut (BH) tree. Previous work has compared the performance of BH trees with that of nearest-neighbor trees and the fast multipole method, but the relative merits of BH and binary trees have not been compared systematically. In carrying...

Patients with type II lissencephaly, a neuronal migration disorder with ectopic neurons, suffer from severe mental retardation, including learning deficits. There is no effective therapy to prevent or correct the formation of neuronal ectopia, which is presumed to cause cognitive deficits. We hypothesized that learning deficits were not solely caused by neuronal ectopia and that postnatal gene ...
