Who Knows Best What the Next Year Will Hold for You? The Validity of Direct and Personality‐based Predictions of Future Life Experiences Across Different Perceivers

European Journal of Personality, EarlyView., 2020
Abstract This study explored the validity of person judgements by targets and their acquaintances (‘informants’) in longitudinally predicting a broad range of psychologically meaningful life experiences. Judgements were gathered from four sources (targets, N = 189; and three types of informants, N = 1352), and their relative predictive validity was ...

Quantum Jackiw-Teitelboim gravity, Selberg trace formula, and random matrix theory

Physical Review Research, 2020
We show that the partition function of quantum Jackiw-Teitelboim (JT) gravity, including topological fluctuations, is equivalent to the partition function of a Maass-Laplace operator of large (imaginary) weight acting on noncompact, infinite-area ...

Effect of heat source/sink on MHD start-up natural convective flow in an annulus with isothermal and isoflux boundaries

Arab Journal of Basic and Applied Sciences, 2020
This article examines the influence of isothermal and isoflux heating/cooling with heat source/sink on unsteady hydromagnetic-free convective flow of a viscous incompressible fluid in an annulus.

Comparison of Two Different Analytical Forms of Response for Fractional Oscillation Equation

Fractal and Fractional, 2021
The impulse response of the fractional oscillation equation was investigated, where the damping term was characterized by means of the Riemann–Liouville fractional derivative with the order α satisfying 0≤α≤2.

Noise recovery for Lévy-driven CARMA processes and high-frequency behaviour of approximating Riemann sums

Electronic Journal of Statistics, 2013
We consider high-frequency sampled continuous-time autoregressive moving average (CARMA) models driven by finite-variance zero-mean Lévy processes. An L^2-consistent estimator for the increments of the driving Lévy process without order selection in advance is proposed if the CARMA model is invertible.
