Everything Is A Matter Of Distance

open access: yesA Peer-Reviewed Journal About
In physics, distance is measured as the product of speed and time; in mathematics, it is defined as the total path travelled by an object from one point to another. Both definitions share an operational clarity but capture only a single dimension of the

Control of finite critical behaviour in a small-scale social system

open access: yesNature Communications, 2017
Proximity to criticality can be advantageous under changing conditions, but it also entails reduced robustness. Here, the authors analyse fight sizes in a macaque society and find not only that it sits near criticality, but also that the distance from ...

The proximities of asteroids and critical points of the distance function

open access: yesSerbian Astronomical Journal, 2010
The proximities are important for different purposes, for example to evaluate the risk of collisions of asteroids or comets with the Solar-System planets. We describe a simple and efficient method for finding the asteroid proximities in the case of elliptical orbits with a common focus.

Dispersal distance is driven by habitat availability and reproductive success in Northern Great Plains piping plovers

open access: yesMovement Ecology, 2021
Background Dispersal is a critical life history strategy that has important conservation implications, particularly for at-risk species with active recovery efforts and migratory species. Both natal and breeding dispersal are driven by numerous selection

Casimir force in the O(n -> infinity) model with free boundary conditions

open access: yes, 2014
We present results for the temperature behavior of the Casimir force for a system with a film geometry with thickness $L$ subject to free boundary conditions and described by the $n\to\infty$ limit of the $O(n)$ model.

Quantized conductance doubling and hard gap in a two-dimensional semiconductor-superconductor heterostructure [PDF]

open access: yes, 2016
The prospect of coupling a two-dimensional (2D) semiconductor heterostructure to a superconductor opens new research and technology opportunities, including fundamental problems in mesoscopic superconductivity, scalable superconducting electronics, and ...

Influence of anatomical barriers on maxillary incisor root resorption after orthodontic treatment with premolar extractions

open access: yesDental Press Journal of Orthodontics, 2012
INTRODUCTION: Apical root resorption is a frequent and occasionally critical problem in orthodontic patients undergoing induced tooth movement. One of the factors that might influence prognosis, especially in maxillary incisors, which most frequently ...

Feasibility and Preliminary Efficacy of Integrative Neuromuscular Training for Childhood Cancer Survivors: A Pilot Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of childhood acute lymphoblastic leukemia (ALL) often exhibit early deficits in muscle and movement competence, which can compromise long‐term health. Integrative neuromuscular training (INT), a multifaceted approach combining fundamental movement activities with strength exercises, may help address these deficits during ...

Deconstructing Depth: Proximity and Contemplation in Déjà Vu

open access: yesFilm-Philosophy, 2018
This article interrogates the persistence of critical frameworks informed by depth-models of hermeneutics, and the repercussions the equation of “depth” with meaningfulness has for the appreciation of the “shallow” aesthetics of post-classical action ...

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...
