A comparison of methods to harmonize cortical thickness measurements across scanners and sites

open access: yesNeuroImage, 2022
Results of neuroimaging datasets aggregated from multiple sites may be biased by site-specific profiles in participants’ demographic and clinical characteristics, as well as MRI acquisition protocols and scanning platforms. We compared the impact of four

First-principles calculations of the diffusion of atomic oxygen in nickel: thermal expansion contribution [PDF]

open access: yes, 2007
Within the framework of density functional theory using the projector augmented-wave (PAW) method, we present some energetic properties of atomic oxygen interstitials in crystalline Ni, i.e.

Microzonation of the Linares, Northeast Mexico area, based on geology and shear-wave velocity measurements [PDF]

open access: yesGeofísica Internacional, 2005
We determined the velocity structure of S-wave (VS), P-wave (VP) and the average shear velocity to 30 meters depth (Vs30) at 30 locations in the Linares, Nuevo León area. VS and VP measurements were made from seismic refraction profiles.

GIS-based regional assessment of seismic site effects considering the spatial uncertainty of site-specific geotechnical characteristics in coastal and inland urban areas

open access: yesGeomatics, Natural Hazards & Risk, 2017
Earthquake-induced hazards are profoundly affected by site effects related to the amplification of ground motions, which are strongly influenced by site-specific geologic conditions such as soil thickness, bedrock depth and soil stiffness.

Application of Single-Station Sigma and Site-Response Characterization in a Probabilistic Seismic-Hazard Analysis for a New Nuclear Site [PDF]

open access: yes, 2014
Aleatory variability in ground-motion prediction, represented by the standard deviation (sigma) of a ground-motion prediction equation, exerts a very strong influence on the results of probabilistic seismic-hazard analysis (PSHA).

Effective Visualization of Object Allocation Sites

open access: yes2018 IEEE Working Conference on Software Visualization (VISSOFT), 2018
Modern software execution platforms are designed to efficiently cope with a massive number of objects creations and destructions. However, ensuring that the memory consumed by an application execution is not excessive remains a manual activity. It is widely known that debugging memory issues is a tedious and error-prone activity.

A study of local site effects in Benevento(Southern Italy) by the analysis of seismic records of explosions

open access: yesAnnals of Geophysics, 1995
In this paper we evalllate the seismic amplification effects in the town of Benevento llsing records of an explo- sion of 500 kg fired at abollt 7 km. Seismic records were obtained at 43 selected sites in the city by digital three-component stations.

Rectenna related atmospheric effects [PDF]

open access: yes, 1980
Possible meteorological effects arising from the existence and operations of a solar power satellite (SPS) system rectenna are examined. Analysis and model simulations in some chosen site situations and meteorological conditions indicate that the ...
