Method to complete flow rate data in automatic fluviometric stations in the karst system of Lagoa Santa area, MG, Brazil

Brazilian Journal of Geology, 2020
Data acquisition by automatic monitoring allows obtaining a large number of data, supporting a better understanding of the monitored region. The use of automated discharge measurement enables a better understanding of floods, the relationship between ...

One-loop four-point function in noncommutative {\cal N}=4 Yang-Mills theory

, 2000
We compute the one-loop four-point function in {\cal N}=4 supersymmetric Yang-Mills theory with gauge group U(N). We perform the calculation in {\cal N}=1 superspace using the background field method and obtain the complete off-shell contributions to the

Dynamical effects of QCD in $q^2 \bar{q}^{2}$ systems

, 2011
We study the coupling of a tetraquark system to an exchanged meson-meson channel, using a pure gluonic theory based four-quark potential {\em matrix} model which is known to fit well a large number of data points for lattice simulations of different ...

Simulation of a Radio Signal Scattered from a Rough Surface by the Method of Stationary Points

Известия высших учебных заведений России: Радиоэлектроника, 2023
Introduction. Many radar and radio navigation problems require adequate (i.e., corresponding to the physics of radio wave scattering under a certain set of conditions) simulation of a radio signal scattered from a rough surface.

Flow Equations without Mean Field Ambiguity [PDF]

, 2003
We compare different methods used for non-perturbative calculations in strongly interacting fermionic systems. Mean field theory often shows a basic ambiguity related to the possibility to perform Fierz transformations.

Relationships between the hard and soft dimensions of the nose in Pan troglodytes and Homo sapiens reveal the positions of the nasal tips of Plio-Pleistocene hominids.

PLoS ONE, 2022
By identifying homogeneity in bone and soft tissue covariation patterns in living hominids, it is possible to produce facial approximation methods with interspecies compatibility.

Critical behavior of disordered systems with replica symmetry breaking

, 2003
A field-theoretic description of the critical behavior of weakly disordered systems with a $p$-component order parameter is given. For systems of an arbitrary dimension in the range from three to four, a renormalization group analysis of the effective ...

Chinese health literacy scale for tuberculosis patients: a study on development and psychometric testing

BMC Infectious Diseases, 2019
Background The role of health literacy on tuberculosis patients has not been evaluated in China, in part because few special health literacy measurements exist.

Application of Non-Perturbative Renormalization Group to Nambu-Jona-Lasinio/Gross-Neveu model at Finite Temperature and Chemical Potential [PDF]

, 1999
The chiral phase structure of the Nambu-Jona-Lasinio/Gross-Neveu model at finite temperature T and finite chemical potential \mu is investigated using (Wilsonian) Non-Perturbative Renormalization Group (NPRG).
