Negative thermal expansion near two structural quantum phase transitions Connor
(2017-12-18)
Recent experimental work has revealed that the unusually strong, isotropic structural negative thermal
expansion in cubic perovskite ionic insulator ScF3 occurs in excited states above a ground state tuned very near a ...
Cosmological Exact Solutions Set of a Perfect Fluid in an Anisotropic Space-Time in Petrov Type D
(2016-06)
In this document a set of exact solutions is obtained by using the model of a perfect fluid on an homogeneous and anisotropic space-time that belongs to (Local Rotational Symmetry) Petrov’s type D. This solutions represent ...
Comparison of commercial dosimetric software platforms in patients treated with 177Lu-DOTATATE for peptide receptor radionuclide therapy
(2020)
Purpose
The aim of this study was to quantitatively compare five commercial dosimetric software platforms based on the analysis of clinical datasets of patients who benefited from peptide receptor radionuclide therapy ...
Study of oxide bands in p-type porous silicon layers
(2019)
The interest in developing fast and reliable chemical and biochemical sensors in an inexpensive way is something that has attracted a lot of efforts in the last decades. One of the potential material candidates is ...
(Hydro)climatological studies of climate change and variability in Central America
(2018-06-26)
This is the presentation of Hugo Hidalgo at the CORDEX Central America and South America Training Workshop on Downscaling Techniques, in La Paz, Bolivia, June 25 to 27, 2018.
OpenDose: Open access resources for nuclear medicine dosimetry
(2020)
Radiopharmaceutical dosimetry depends on the localization in
space and time of radioactive sources and requires the estimation
of the amount of energy emitted by the sources deposited within
targets. In particular, when ...
Pressure dependence of ferroelectric quantum critical fluctuation
(2019-12-13)
Phase transitions to a long-range-ordered state driven by a softened phonon mode are ubiquitous across condensed matter physics, but the evolution of such a mode as the system is tuned to or from the transition has never ...
Black hole binaries with natal kicks
(2023)
Las observaciones de más de 90 ondas gravitacionales observadas por la colaboración LIGO/VIRGO/KAGRA, han permitido obtener información sobre sistemas binarios compactos, como sus masas y espines. El parámetro de espín ...
