Optimal firms' mix in oligopoly with twofold environmental externality [PDF]

open access: yes, 2014
We charaterise the socially optimal mix of firms in an oligopoly with both profit-seeking and labour-managed firms. The policy maker faces a twofold externality: (i) production entails the exploitation of a common pool natural resource and (ii ...

Thermal Conductance for Single Wall Carbon Nanotubes

open access: yes, 2002
We report a theoretical analysis of the phonon thermal conductance, \kappa (T), for single wall carbon nanotubes (SWCN). In a range of low temperatues up to 100K, \kappa (T) of perfect SWCN is found to increase with temperature, approximately, in a ...

Regulating Environmental Externalities Through Public Firms: A Differential Game [PDF]

open access: yes, 2011
We investigate the possibility of using public firms to regulate polluting emissions in a Cournot oligopoly where production takes place at constant returns to scale and entails a negative environmental externality. We model the problem as a differential

Simulations of composite carbon films with nanotube inclusions

open access: yes, 2005
We study the interfacial structure, stability, and elastic properties of composite carbon films containing nanotubes. Our Monte Carlo simulations show that Van der Waals forces play a vital role in shaping up the interfacial geometry, producing a curved ...

Hydrogen diffusion in potassium intercalated graphite studied by quasielastic neutron scattering [PDF]

open access: yes, 2012
The graphite intercalation compound KC24 adsorbs hydrogen gas at low temperatures up to a maximum stoichiometry of KC_(24)(H_2)_2, with a differential enthalpy of adsorption of approximately −9 kJ mol^(−1). The hydrogen molecules and potassium atoms form

Ab initio modeling of quantum transport properties of molecular electronic devices [PDF]

open access: yes, 2001
We report on a self-consistent ab initio technique for modeling quantum transport properties of atomic and molecular scale nanoelectronic devices under external bias potentials.

Cognitive and sociodemographic data of elderly individuals with Alzheimer's Disease attended by a family‐support service in a southern city of Brazil

open access: yesAlzheimer's &Dementia, Volume 21, Issue S6, December 2025.
Abstract Background Alzheimer's disease (AD) is the most common form of dementia worldwide, particularly among elderlies and women, whose risk increases with advancing age, lifestyle, and genetic background. Family history, education level, and income are factors that may influence the progression of AD.

Minimal effects of waterborne exposure to single-walled carbon nanotubes on behaviour and physiology of juvenile rainbow trout (Oncorhynchus mykiss). [PDF]

open access: yes, 2014
Fish behaviours are often considered to be sensitive endpoints of waterborne contaminants, but little attention has been given to engineered nanomaterials.

Word Representation Models for Morphologically Rich Languages in Neural Machine Translation [PDF]

open access: yesSWCN@EMNLP, 2016
Out-of-vocabulary words present a great challenge for Machine Translation. Recently various character-level compositional models were proposed to address this issue.

Dielectric functions and collective excitations in MgB_2

open access: yes, 2001
The frequency- and momentum-dependent dielectric function $\epsilon{(\bf q,\omega)}$ as well as the energy loss function Im[-$\epsilon^{-1}{(\bf q,\omega)}$\protect{]} are calculated for intermetallic superconductor $MgB_2$ by using two {\it ab initio ...
