Final state interaction in D+→K−π+π+D^+\to K^-\pi^+\pi^+ with KπK\pi I=1/2 and 3/2 channels

The final state interaction contribution to $D^+$ decays is computed for the $K^-\pi^+\pi^+$ channel within a light-front relativistic three-body model for the final state interaction. The rescattering process between the kaon and two pions in the decay channel is considered. The off-shell decay amplitude is a solution of a four-dimensional Bethe-Salpeter equation, which is decomposed in a Faddeev form. The projection onto the light-front of the coupled set of integral equations is performed via a quasi-potential approach. The S-wave $K\pi$ interaction is introduced in the resonant isospin $1/2$ and the non-resonant isospin $3/2$ channels. The numerical solution of the light-front tridimensional inhomogeneous integral equations for the Faddeev components of the decay amplitude is performed perturbatively. The loop-expansion converges fast, and the three-loop contribution can be neglected in respect to the two-loop results for the practical application. The dependence on the model parameters in respect to the input amplitude at the partonic level is exploited and the phase found in the experimental analysis, is fitted with an appropriate choice of the real weights of the isospin components of the partonic amplitude. The data suggests a small mixture of total isospin $5/2$ to the dominant $3/2$ one. The modulus of the unsymmetrized decay amplitude, which presents a deep valley and a following increase for $K\pi$ masses above $1.5$ GeV, is fairly reproduced. This suggests the assignment of the quantum numbers $0^+$ to the isospin 1/2 $K^*(1630)$ resonance

Bases de dados sintéticas com anotação automática para detecção de frutos.

Com o objetivo de criar uma base de dados sintéticos para detecção de laranjas, foram utilizadas ferramentas de computação gráfica, a fim de gerar imagens fotorrealistas. Para que houvesse uma anotação automática dessas imagens, tirando proveito do fato de serem artificiais, geradas por computador, utilizou-se de conhecimentos de programação e geometria projetiva.CIIC 2023.

Effects Of A Physical Exercise Program In Patients Diagnosed With Schizophrenia

Objectives: To report the effects of a pilot physical exercise program on the quality of life, physical capacity, psychopathological symptoms, body constitution and biochemical parameters in patients with schizophrenia. Methods: In October 2013, a protocol was established between the Sports Department of the University of Évora and the Mental Health Department of Espírito Santo Hospital. A pilot study was initiated to promote physical and psychological rehabilitation of schizophrenic outpatients. Ten patients accepted to participate on the present research. The exercise program consisted of 20 training sessions with 60 minutes each, within a 20-week period. All sessions were supervised by a professional on physical activity. Baseline data were collected prior to intervention and include: a) quality of life assessed with the Functional Assessment Staging Scale, with the Brief Symptom Inventory and the Positive and Negative Syndrome Scale b) health related battery of tests; c) body composition with a DXA; d) blood analysis. The same data will be collected by the end of the intervention (June 2014). Initial and final results will be then correlated and used to investigate associations among quantitative independent variables. Results: By the end of the program (June 2014) it is expected for the participants to show an improvement in physical performance, body composition and the reduction of cardiovascular risk. Concerning psychopathological features, it is expected an improvement in Quality of Life and Functional Assessment, a significant decrease in the Brief Symptom Inventory and in the Positive and Negative Symptom Scale. Conclusions: Schizophrenia is a disease with serious physical repercussions, caused not only by the disease itself but also because of antipsychotics side effects. This pilot physical exercise program, despite its methodological limitations, emphasized the relevance of including serious mentally ill patients in rehabilitation programs in order to promote the recovery of functional abilities
