The Smart System 1: evidence for the intuitive nature of correct responding on the bat-and-ball problem

open access: yesThinking and Reasoning, 2019
Influential work on reasoning and decision-making has popularised the idea that sound reasoning requires correction of fast, intuitive thought processes by slower and more demanding deliberation.

Two Area Preserving Maps from the Square to the p-Ball

open access: yesMathematical Modelling and Analysis, 2017
We construct two area preserving maps from the square to the p-ball (the domain defined by |x|p + |y|p ≤ |a|p ) and use them to obtain low distorted uniform grids on the p-ball.

Gauged Q ball in a piecewise parabolic potential

open access: yes, 2002
Q ball solutions are considered within the theory of a complex scalar field with a gauged U(1) symmetry and a parabolic-type potential. In the thin-walled limit, we show explicitly that there is a maximum size for these objects because of the repulsive

Variational skinning of an ordered set of discrete 2D balls [PDF]

open access: yes, 2008
This paper considers the problem of computing an interpolating envelope of an ordered set of 2D balls. By construction, the envelope is constrained to be C1 continuous, and for each ball, it touches the ball at a point and is tangent to the ball at ...

Economy of Impressions: Reconstruction of Historical Practices of the Cultural Heritage of St. Petersburg

open access: yesУправленческое консультирование, 2018
This article presents some results of the current study of ball’s culture in the framework of the project on the reconstruction of historical practices of the cultural heritage of St. Petersburg, an UNESCO World Heritage site. The  economy of impressions

Uniqueness of stable capillary hypersurfaces in a ball [PDF]

open access: yesMathematische Annalen, 2017
In this paper we prove that any immersed stable capillary hypersurfaces in a ball in space forms are totally umbilical. Our result also provides a proof of a conjecture proposed by Sternberg and Zumbrun (J Reine Angew Math 503:63–85, 1998). We also prove

Network Localization of Fatigue in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Fatigue is among the most common symptoms and one of the main factors determining the quality of life in multiple sclerosis (MS). However, the neurobiological mechanisms underlying fatigue are not fully understood. Here we studied lesion locations and their connections in individuals with MS, aiming to identify brain networks ...

Hopfield Neural Networks for Online Constrained Parameter Estimation With Time‐Varying Dynamics and Disturbances

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
This paper proposes two projector‐based Hopfield neural network (HNN) estimators for online, constrained parameter estimation under time‐varying data, additive disturbances, and slowly drifting physical parameters. The first is a constraint‐aware HNN that enforces linear equalities and inequalities (via slack neurons) and continuously tracks the ...

Food insecurity in paradise

open access: yesJournal of Agriculture, Food Systems, and Community Development
Despite being a world-class tourist destination, the U.S. Virgin Islands (USVI—St. Thomas, St. Croix, and St. John) face significant challenges related to diversified crop production, food distribution, and food security.

A Mass-Spring-Damper Model of a Bouncing Ball (Conference proceeding) [PDF]

open access: yes, 2005
The mechanical properties of a vertically dropped ball, represented by an equivalent mass-spring-damper model, are related to the coefficient of restitution and the time of contact of the ball during one bounce with the impacting surface. In addition, it
