Being mindful of our insomnia can get us to sleep? - Mindfulness aproach to sleep disorders
Autor: R. B. Cohen, I. M. Pereira, M. G. Marguilho, M. C. Sousa, B. V. Ferreira
Publikováno v: European Psychiatry, Vol 66, Pp S1104-S1104 (2023)
Introduction Sleep disorders (e.g., insomnia) are extremely prevalent in our population and are intimately associated with distress and productivity impairment. It is estimated that between 40 to 60% of people suffering from a sleep disorder have an

Suicidal ideation in older people, a public health matter
Autor: R. B. Cohen, I. M. Pereira, M. M. Garrido, B. V. Ferreira, M. C. Sousa
Publikováno v: European Psychiatry, Vol 66, Pp S843-S843 (2023)
Introduction Suicide in older people is a critical public and mental health issue which requires attention, given that the ageing population is increasing. Multiple factors, including biological, psychological, and social stressors increase suicidal

Low mass strange stars and the compact star 1E1207.4-5209 in the field correlator method
Autor: F. I. M. Pereira
Publikováno v: Physical Review D. 104
We investigate the possible existence of anomalous mass defects in the low mass region of stellar sequences of strange stars. We employ the nonperturbative equation of state derived in the framework of the Field Correlator Method to describe the hydr

Nonextensive effects on the phase structure of quantum hadrodynamics
Autor: Regina H. Silva, J.S. Alcaniz, F. I. M. Pereira
Publikováno v: Physics Letters A. 373:4214-4218
In this Letter, we investigate nonextensive effects on phase transition in nuclear matter in the context Walecka many-body field theory. A difference is observed when the results calculated for the nuclear matter at vanishing baryon density is compar

Non-Gaussian statistics and the relativistic nuclear equation of state
Autor: J.S. Alcaniz, Regina H. Silva, F. I. M. Pereira
Publikováno v: Nuclear Physics A. 828:136-148
We investigate possible effects of quantum power-law statistical mechanics on the relativistic nuclear equation of state in the context of the Walecka quantum hadrodynamics theory. By considering the Kaniadakis non-Gaussian statistics, characterized

GRAVITATIONAL COLLAPSE OF A MASSLESS SCALAR FIELD AND A PERFECT FLUID WITH SELF-SIMILARITY OF THE FIRST KIND IN 2+1 DIMENSIONS
Autor: R. Chan, F. I. M. Pereira
Publikováno v: International Journal of Modern Physics D. 17:2143-2158
Self-similar solutions of a collapsing perfect fluid and a massless scalar field with kinematic self-similarity of the first kind in 2+1 dimensions are obtained. Their local and global properties of the solutions are studied. It is found that some of

Consistent nonadditive approach and nuclear equation of state
Autor: J. S. Alcaniz, A.P. Santos, F. I. M. Pereira, R. Silva
By using a $q$-calculus, the Walecka many-body field theory was studied in the context of the Tsallis framework. The most important aspect of the application of the $q$-calculus to the nonadditive formulation of QHD-I is that it naturally emerges as

Nonextensive effects on the relativistic nuclear equation of state
Autor: J.S. Alcaniz, Regina H. Silva, F. I. M. Pereira
Publikováno v: Physical Review C. 76
The Walecka many-body field theory is investigated in the context of quantum nonextensive statistical mechanics, characterized by a dimensionless parameter $q$. We consider nuclear matter described statistically by a power-law distribution which gene
