Some considerations regarding preventable diseases and their prevention

Some Considerations regarding Lorentz-violating Theories

We investigate the compatibility of Lorentz-violating quantum field theories with the requirements of causality and stability. A general renormalizable model for free massive fermions indicates that these requirements are satisfied at low energies provided the couplings controlling the breaking are small. However, for high energies either microcausality or energy positivity or both are violated...

Some considerations regarding the immunology of leprosy.

In leprosy, an infection produced by a mycobacterium, M. leprae, which is an obligatory intracellular parasite, it is the cell-mediated immunologic phenomena which intervene as defensive mechanisms, and not circulating antibodies. A high proportion of the general population is immune to the disease. It seems that in each generation there is a small group of persons susceptible to infection who ...

T Some Considerations Regarding Mathematical Semiosis

The discussion on the possibility of machines to achieve semiosis (meaning process) is a very controversial debate within Artificial Intelligence and Cognitive Science. In this work, we define meaning process in an entirely mathematical framework. We call the “transposition” of the Peircean theory to an abstract mathematical model as “Mathematical Semiosis”. By doing this, we aim at growing a m...

Cancer Patients’ Survival: Standard Calculation Methods And Some Considerations Regarding Their Interpretation

BACKGROUND Cancer patients' survival is an extremely important but complex indicator for assessing regional or global inequalities in diagnosis practices and clinical management of cancer patients. The population-based cancer survival comparisons are available through international projects (i.e. CONCORD, EUROCARE, OECD Health Reports) and online systems (SEER, NORDCAN, SLORA). In our research ...
