Giant vortices in combined harmonic and quartic traps

, 2003
We consider a rotating Bose-Einstein condensate confined in combined harmonic and quartic traps, following recent experiments [V. Bretin, S. Stock, Y. Seurin and J. Dalibard, cond-mat/0307464]. We investigate numerically the behavior of the wave function

Maternal Obesity, Gestational Diabetes Mellitus and Offspring's Body Mass Index Trajectories From Birth to Age 6 Years: Glucose in Relation to Women and Babies' Health (GrownB) Study

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Objective To examine whether offspring born to mothers with overweight/obesity, gestational diabetes mellitus (GDM) or both exhibit different body mass index (BMI) trajectories from birth to 6 years old. Design Retrospective cohort study. Setting The Glucose in Relation to Women and Babies' Health (GrownB) Study at the University of California,

Does the All‐Star Award Affect Chinese Analysts' Performance? Evidence From a Regression Discontinuity Design and the Field Le prix All‐Star influence‐t‐il le rendement des analystes chinois ? Données probantes issues d'une régression sur discontinuité et du terrain

Contemporary Accounting Research, EarlyView.
ABSTRACT This paper examines the effect of the All‐Star award on the performance of Chinese financial analysts. Leveraging unique voting data from 2007 to 2016 and a regression discontinuity design (RDD), we find that the All‐Star award significantly enhances recipients' fundamental analysis. Awarded analysts issue more accurate earnings forecasts, and

Modelling non‐linear psychological processes: Reviewing and evaluating non‐parametric approaches and their applicability to intensive longitudinal data

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Psychological concepts are increasingly understood as complex dynamic systems that change over time. To study these complex systems, researchers are increasingly gathering intensive longitudinal data (ILD), revealing non‐linear phenomena such as asymptotic growth, mean‐level switching, and regulatory oscillations.

Vortices in Bose-Einstein condensates with anharmonic confinement

, 2003
We examine an effectively repulsive Bose-Einstein condensate of atoms, that rotates in a quadratic-plus-quartic trapping potential. We investigate the phase diagram of the system as a function of the angular frequency of rotation and of the coupling ...

Revisiting RGEs for general gauge theories

Nuclear Physics B, 2019
We revisit the renormalisation group equations (RGE) for general renormalisable gauge theories at one- and two-loop accuracy. We identify and correct various mistakes in the literature for the β-functions of the dimensionful Lagrangian parameters (the ...

Field Theory for Function Fields of Plane Quartic Curves

Journal of Algebra, 2000
Let \(K\) be the rational function field of a smooth plane curve \(C\) of degree \( d\) (\(d\geq 2)\) defined over an algebraic number field \(k\) of characteristic zero. If \(K_m\) denotes a maximal rational subfield of \(K\), the authors of the paper under review answer, in the case where \(C\) is a quartic curve, the following questions. (1) When is

Investigating the molecular mechanisms underlying the anti‐CRISPR function of AcrIIA13b protein

The FEBS Journal, EarlyView.
Anti‐CRISPR protein AcrIIA13b inhibits CRISPR–Cas9 function by preventing target DNA engagement. The Cas9–sgRNA ribonucleoprotein (RNP) normally recognizes the protospacer adjacent motif (PAM) duplex to initiate DNA cleavage. AcrIIA13b binding to the PAM‐interacting WED–PI domain blocks this recognition, leaving the target DNA intact.

A Comparative Review of Specification Tests for Diffusion Models

International Statistical Review, EarlyView.
Summary Diffusion models play an essential role in modelling continuous‐time stochastic processes in the financial field. Therefore, several proposals have been developed in the last decades to test the specification of stochastic differential equations.

Analytic approximate charged black hole solutions in Einstein–quartic gravity

Frontiers in Astronomy and Space Sciences
In this work, we employ continued fraction expansions to derive analytical, approximate charged black hole solutions in Einstein–Maxwell–quartic gravity, a theory that introduces quartic curvature corrections to the Einstein–Hilbert action.
