Thermodynamics of doped Kondo insulator in one dimension: Finite Temperature DMRG Study

open access: yes, 1998
The finite-temperature density-matrix renormalization-group method is applied to the one-dimensional Kondo lattice model near half filling to study its thermodynamics. The spin and charge susceptibilities and entropy are calculated down to T=0.03t.

A crossover study of short daily haemodialysis [PDF]

open access: yesNephrology Dialysis Transplantation, 2005
The benefits of daily haemodialysis (DHD) compared to conventional three times per week haemodialysis (CHD) have been described in a number of observational studies. Most of these previous studies however have not been performed with rigorous controls.We performed a crossover study following an A-B-A design: phase A was 4 weeks of thrice weekly ...

The Relationship between Chocolate Consumption and the Severity of Acne Lesions−A Crossover Study

open access: yesFoods
The aim of this study was to assess the relationship between the daily consumption of 50 g of chocolate with 85% cocoa content and the severity of acne lesions. Methods: The study involved 92 participants with acne who were divided into two groups, A (n =

Evaluation of mint efficacy regarding dysmenorrhea in comparison with mefenamic acid: A double blinded randomized crossover study

open access: yesIranian Journal of Nursing and Midwifery Research, 2016
Background: Menthol is the most important active material in mint and different mechanisms have been suggested for the way mint functions, most of which emphasize its analgesic effect owing to the presence of a group of temporary protein receptors.

Resistance to learning and the evolution of cooperation [PDF]

open access: yes, 2009
In many evolutionary algorithms, crossover is the main operator used in generating new individuals from old ones. However, the usual mechanism for generating offsprings in spatially structured evolutionary games has to date been clonation.

Chaotic Transport in the Symmetry Crossover Regime with a Spin-orbit Interaction

open access: yes, 2010
We study a chaotic quantum transport in the presence of a weak spin-orbit interaction. Our theory covers the whole symmetry crossover regime between time-reversal invariant systems with and without a spin-orbit interaction.

A genetic algorithm for the mixed flow shop problem [PDF]

open access: yes, 2019
In this thesis we present a new interesting version of the mixed flow shop se-quencing problem, which at the same time is a version of the classic flow shop,a very common topic on operations research.We propose a genetic algorithm to solve it that we ...

Mean-field expansion for spin models with medium-range interactions

open access: yes, 1999
We study the critical crossover between the Gaussian and the Wilson-Fisher fixed point for general O(N)-invariant spin models with medium-range interactions.

Spectrum and Dynamics of the BCS-BEC crossover from a few-body perspective

open access: yes, 2007
The spectrum of two spin-up and two spin-down fermions in a trap is calculated using a correlated gaussian basis throughout the range of the BCS-BEC crossover. These accurate calculations provide a few-body solution to the crossover problem.
