Individual Sleep Problems Are Associated With an Accelerated Decline in Multiple Cognitive Functions in Older Adults

Journal of Sleep Research, EarlyView.
ABSTRACT Poor sleep is a known risk factor of cognitive disorders, but the role of individual sleep problems in age‐related cognitive changes remains unclear. This study used two complementary statistical models to estimate nonlinear trajectories of decline in four domains of cognitive functioning in the age period between 55 and 100 years depending on

Chern-Simons perturbative series revisited

Physics Letters B, 2021
A group-theoretical structure in a perturbative expansion of the Wilson loops in the 3d Chern-Simons theory with SU(N) gauge group is studied in symmetric approach.

Resummation at finite conformal spin

Journal of High Energy Physics, 2019
We generalize the computation of anomalous dimension and correction to OPE coefficients at finite conformal spin considered recently in [1, 2] to arbitrary space-time dimensions.

Oued Chebeika 002: A new CI1 meteorite linked to outer solar system bodies

Meteoritics &Planetary Science, EarlyView.
Abstract CI1 chondrites are rare meteorites with high scientific value. In fact, they are the most chemically primitive meteorites and show evidence of intense parent‐body aqueous alteration. They also share strong similarities with samples from Ryugu and Bennu asteroids returned by the JAXA Hayabusa2 and NASA's OSIRIS‐REx missions.

Integral Representations of the Wilson Polynomials and the Continuous Dual Hahn Polynomials

Advances in Applied Mathematics, 1999
AbstractWe give representations of the Wilson polynomials and the continuous dual Hahn polynomials in terms of multidimensional generalizations of Barnes type integrals. Motivation is to study the Barnes type integrals from the viewpoint of the de Rham theory and holonomic systems.

Efficiencies of and Motivations for Contracting Out in the Public Sector: The Case of Social Services in Spain

Public Administration, EarlyView.
ABSTRACT Debates on contracting out to the private sector is primarily focused on the cost efficiency of its provision, drawing on experiences with hard or technical services such as waste and water management. This paper focuses on a growing interest in the role and impact of sourcing decisions in softer or more human‐centered services, such as social

Perturbative analysis of the colored Alexander polynomial and KP soliton τ-functions

Nuclear Physics B, 2021
In this paper we study the group theoretic structures of colored HOMFLY polynomials in a specific limit. The group structures arise in the perturbative expansion of SU(N) Chern-Simons Wilson loops, while the limit is N→0.

The Role of International Trade Agreements During Economic and Policy Crises: Evidence From U.S. Firm Dynamics

Review of International Economics, EarlyView.
ABSTRACT We use U.S. firm exports from 2003 to 2011 to establish facts about export dynamics in a crisis marked by economic and policy uncertainty. Uncertainty about foreign income, trade protection, and their interaction dampen export investments, which can be partially offset by trade agreements that mitigate policy uncertainty. We find a significant
