Mind wandering (i.e. engaging in cognitions unrelated to the current demands of the external environment) reflects the cyclic activity of two core processes: the capacity to disengage attention from perception (known as perceptual decoupling) and the ability to take explicit note of the current contents of consciousness (known as meta-awareness). Research on perceptual decoupling demonstrates t...

Statins inhibit cholesterol biosynthesis. Their main effect is a decrease in circulating levels of LDL cholesterol, which translates into a ~ 20% relative reduction of major vascular events and coronary mortality per mmol/L LDL reduction achieved. Statins are efficient in preventing first cardiovascular events, but the cost-efficiency of primary prevention remains controversial. In primary prev...

Objective(s) As an important class of natural products, coumarins exhibit many biological activities and the diversity of their bioactivity is so huge that the pharmacological promiscuity has been applied on their case. Oxypeucedanine also named as prangolarin is a linear furanocoumarin with an oxygenated prenylated substitution at C-5 of the nucleus. To our knowledge, there are few reports on...

Problems with the lexical substitution mechanism of the C preprocessor are well known. We resolve these problems with a new syntax-based substitution mechanism for C++ based on meta-variables and metafunctions. Implementation of these meta-concepts in a C++ style leads naturally to meta-expressions and then meta-statements and a generalisation of C++ syntax. We show how meta-compilation renders...

Meta-programming is a well-known technique widely used in logic programming and artificial intelligence. Meta-interpreters are powerful tools especially for writing expert systems in general and for writing their inference machines in particular. While the classical approach to meta-interpretation is based on the syntactic definition of a meta-interpreter, new approach presented in this paper c...
