Causal Classical Theory of Radiation Damping
It is shown how initial conditions can be appropriately defined for the
integration of Lorentz-Dirac equations of motion. The integration is performed
\QTR{it}{forward} in time. The theory is applied to the case of the motion of
an electron in an intense laser pulse, relevant to nonlinear Compton
scattering.Comment: 8 pages, 2 figure
Entanglement of pseudo-Hermitian random states
In a recent paper (arXiv:1905.07348v1), Dyson scheme to deal with density
matrix of non-Hermitian Hamiltonians has been used to investigate the
entanglement of states of a PT-symmetric bosonic system. They found that von
Neumann entropy can show a different behavior in the broken and unbroken
regime. We show that their results can be recast in terms of an abstract model
of pseudo-Hermitian random matrices. It is found however that, although the
formalism is practically the same, the entanglement is not of Fock states but
of Bell states.Comment: 15 pages, 2 figure
The association between atypical femoral fractures and biphosphonates: review of the literature
ntrodução: Os bifosfonatos são a principal classe farmacológica usada na terapia anti-reabsortiva para a Osteoporose.
Apesar da sua eficácia comprovada, vários trabalhos recentes sugeriram uma associação entre estes fármacos e o aparecimento
de fraturas atípicas do fémur (FA). Materiais e Métodos: Os autores efetuaram uma revisão da literatura relativa a esta temá-
tica na língua inglesa e portuguesa. Foram revistos 426 resumos e selecionados 94 artigos para revisão final. Resultados: A
mudança dos critérios na definição e a qualidade dos estudos realizados são os principais limitadores na compreensão desta
associação. Apesar de haver uma associação aparente entre estes fármacos e as FA, a intensidade desta é menos clara. Por
outro lado os bifosfonatos têm décadas de experiência clínica, com vários ensaios clínicos e metanálises a demonstrar a sua
eficácia a prevenir uma proporção muito mais significativa de fraturas osteoporóticas. Conclusões: Os bifosfonatos continuam
a ser a escolha de primeira linha no tratamento da Osteoporose. São necessários mais estudos por forma a estabelecer com
clareza a relação entre os bifosfonatos e FA e que elucidem como controlar e prevenir este fenómeno.info:eu-repo/semantics/publishedVersio

Karakteristik Kimia dan Mutu Sensori Bakso Ikan Patin dengan Penggunaan Tepung Bonggol Pisang dan Tapioka
Meatballs is a processed meat product that is very popular among people. This study was aimed to obtain the best ratio of banana excrescence flour and tapioca on the quality of patin fish meatballs.This research was conducted by using Completely Randomized Design (CRD) experiment with five treatments and three replications. The data were analyzed by ANOVA followed by Duncan\u27s New Multiple Range Test (DNMRT) at 5% level. The treatments in this research were P1 (ratio banana excrescence flour and tapioca 0:3), P2 (ratio banana excrescence flour and tapioca 1:2), P3 (ratio banana excrescence flour and tapioca 1:1), P4 (ratio banana excrescence flour and tapioca 2:1), and P5 (ratio banana excrescence flour and tapioca 3:0). The results analysisof variance show that ratio of the banana excrescence flour and tapioca significantly affected themoisture, ash, fiber, fat and protein contentsas well as sensory evaluation of meatballs. The best formulations was obtained on the meatballs are P2 with ratio banana excrescence flour and tapioca 1:2 which had a moisture content 68.34%, ash content 1.93%, fat content 0.81%, fiber content of 1.51% and protein content 12. 92%.Meatballs is a processed meat product that is very popular among people.

Family of generalized random matrix ensembles
Using the Generalized Maximium Entropy Principle based on the nonextensive q
entropy a new family of random matrix ensembles is generated. This family
unifies previous extensions of Random Matrix Theory and gives rise to an
orthogonal invariant stable Levy ensemble with new statistical properties. Some
of them are analytically derived.Comment: 13 pages and 2 figure
Level density for deformations of the Gaussian orthogonal ensemble
Formulas are derived for the average level density of deformed, or
transition, Gaussian orthogonal random matrix ensembles. After some general
considerations about Gaussian ensembles we derive formulas for the average
level density for (i) the transition from the Gaussian orthogonal ensemble
(GOE) to the Poisson ensemble and (ii) the transition from the GOE to GOEs.Comment: 7 pages revtex4, 5 eps figures, submitted to Phys. Rev.
