Non-monotonic pressure evolution of the upper critical field in superconducting FeSe [PDF]

open access: yes, 2016
The pressure dependence of the upper critical field, $H_\textrm{c2,c}$, of single crystalline FeSe was studied using measurements of the inter-plane resistivity, $\rho_{\textrm{c}}$ in magnetic fields parallel to tetragonal $c$-axis. $H_\textrm{c2,c}(T)$

Quelles organisations de la mobilité plus durables et moins dépendantes de la voiture dans les espaces ruraux à faible densité ? L’exemple du Parc naturel régional Loire-Anjou-Touraine

open access: yesDéveloppement Durable et Territoires, 2013
Two phenomena will in the next years hinder the rural populations’ mobility practices: the environmental recommendations of the French law “Grenelle 2”, which encourages the development of the most accessible areas only; the increasing cost of energy and

Resonant photon tunneling enhancement of the radiative heat transfer [PDF]

open access: yes, 2004
We study the dependence of the heat transfer between two semi-infinite solids on the dielectric properties of the bodies. We show that the heat transfer at short separation between the solids may increase by many order of magnitude when the surfaces are ...

Introducing localgauss, an R Package for Estimating and Visualizing Local Gaussian Correlation

open access: yesJournal of Statistical Software, 2014
Quantifying non-linear dependence structures between two random variables is a challenging task. There exist several bona-fide dependence measures able to capture the strength of the non-linear association, but they typically give little information ...

Cosmological parameter dependence in local string theories of structure formation [PDF]

open access: yes, 1999
We perform a new and accurate study of the dependence on cosmological parameters of structure formation with local cosmic strings. The crucial new ingredients are the inclusion of the effects of gravitational backreaction on the evolution of the network,

hergm: Hierarchical Exponential-Family Random Graph Models

open access: yesJournal of Statistical Software, 2018
We describe the R package hergm that implements hierarchical exponential-family random graph models with local dependence. Hierarchical exponential-family random graph models with local dependence tend to be superior to conventional exponential-family ...

Estimating the extremal index through local dependence [PDF]

open access: yes, 2015
The extremal index is an important parameter in the characterization of extreme values of a stationary sequence. Our new estimation approach for this parameter is based on the extremal behavior under the local dependence condition D$^{(k)}$($u_n$).

Joint Testlet Cognitive Diagnosis Modeling for Paired Local Item Dependence in Response Times and Response Accuracy

open access: yesFrontiers in Psychology, 2018
In joint models for item response times (RTs) and response accuracy (RA), local item dependence is composed of local RA dependence and local RT dependence. The two components are usually caused by the same common stimulus and emerge as pairs.

On the competition between interface energy and temperature in phase transition phenomena

open access: yesApplications in Engineering Science, 2020
Phase nucleation and propagation phenomena can be characterized by a cooperative behavior regulated by non local interactions between the multistable domains and with the loading device.

Anomalous thermal conductivity and local temperature distribution on harmonic Fibonacci chains [PDF]

open access: yes, 2002
The harmonic Fibonacci chain, which is one of a quasiperiodic chain constructed with a recursion relation, has a singular continuous frequency-spectrum and critical eigenstates. The validity of the Fourier law is examined for the harmonic Fibonacci chain
