Theoretical Status of Pentaquarks [PDF]

open access: yes, 2007
We review the current status of the theoretical pentaquark search from the direct QCD calculation. The works from the QCD sum rule and the lattice QCD in the literature are carefully examined.

Anomalous Electric Fields in n-InSb under High Magnetic Fields. I-Experiment [PDF]

open access: yes, 1976
An investigation was made of the anomalous electric field in its various aspects in n-type InSb subjected to strong magnetic field at 77K and 273K, which lead to the conclusion that no open contradiction arose between a part of the present observations ...

A numerical model for water-oil flow in naturally fractured reservoirs

open access: yesVietnam Journal of Mechanics, 2004
This paper describes the development of a three-dimensional, two-phase model for simulating the flow of water and oil in naturally fractured reservoirs. The model is based on the dual porosity approach.

Calculation of fracture mechanic parameters via FEM for some cracked plates under different loads

open access: yesVietnam Journal of Mechanics, 2006
This paper describes some results in analyzing cracked plates via FEM based on the procedures in CASTEM 2000 [1]. The basic methods for computing the crack parameters by the finite element analysis are presented. Some programs written by GIBIAN languages

Integration of X-ray absorption fine structure databases for data-driven materials science

open access: yesScience and Technology of Advanced Materials: Methods, 2023
With the aim of introducing data-driven science and establishing an infrastructure for making X-ray absorption fine structure (XAFS) spectra findable and reusable, we have integrated XAFS databases in Japan. This integrated database (MDR XAFS DB) enables

Response of Single Polymers to Localized Step Strains [PDF]

open access: yes, 2008
In this paper, the response of single three-dimensional phantom and self-avoiding polymers to localized step strains are studied for two cases in the absence of hydrodynamic interactions: (i) polymers tethered at one end with the strain created at the ...

An adoption model of mHealth applications that promote physical activity

open access: yesCogent Psychology, 2020
Physical activity is one of the ways to promote a healthy and balanced life. There is growing evidence that physical activity can be promoted through the use of mHealth applications.

GEOAI FOR MARINE ECOSYSTEM MONITORING: A COMPLETE WORKFLOW TO GENERATE MAPS FROM AI MODEL PREDICTIONS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2023
Mapping and monitoring marine ecosystems imply several challenges for data collection and processing: water depth, restricted access to locations, instrumentation costs or weather constraints for sampling, among others. Nowadays, Artificial Intelligence (

Low-frequency discrete breathers in long-range systems without on-site potential [PDF]

open access: yes, 2017
We propose a new mechanism of long-range coupling to excite low-frequency discrete breathers without the on-site potential. This mechanism is universal in long-range systems irrespective of the spatial boundary conditions, of topology of the inner degree
