Conventional country risk and political risk indexes, to formalize the process, have attempted to standardize and generalize assessment models for factors that are highly context specific. Hence, the value derived from traditional political risk indexes lack precision and are therefore less reliable....

Carbamazepine and sodium valproate are one of the most common antiepileptic medications used in clinical practice. The period of treatment is commonly associated with benign alternation of the liver enzymes due to drug metabolism. Evaluation of asymptomatic enzymatic changes could be challenging to the...

The algebra 𝒣≔H1,ν(I2(2m+1)) of observables of the Calogero model based on the root system I2(2m + 1) has an m-dimensional space of traces and an (m + 1)-dimensional space of supertraces. In the preceding paper we found all values of the parameter ν for which either the space of traces contains...

Objective: Carotid-femoral Pulse Wave velocity (cfPWV), the gold standard for measuring stiffness, is a marker of organ damage (OLD). Even though cfPWV correlates with casual (BPc), central (CBP) and ambulatory (ABPM) blood pressure (BP), evidence is limited for resistant hypertension (RH). Method:...

Background: Pulse Wave Velocity (PWV) is a measure of arterial stiffness and vascular aging and an important parameter for cardiovascular risk stratification. A previous study showed high prevalence rates of early vascular aging in an adult population from the North of Portugal. The aim of this study...
