Compounds of indicative conditionals present some puzzling phenomena. Perhaps most striking, some nested indicative conditionals are uninterpretable. Proponents of NTV hold that indicative conditionals do not have truth values, and they use this to explain why nested indicative conditionals are sometimes uninterpretable: the embedded conditional does not provide the truth conditions needed by t...

Background and objectives: There is a growing trend towards investigating natural products as sources of compounds with biological effects and many researches have been carried out in order to find effective medications against many diseases. Cancer is no exception and studies focusing on evaluating the effects of different materials on DNA, give valuable information in cancer researches and ca...

And what if the only reality in existence was virtual reality? The individual identity in virtual reality has always been studied with regards to individual identity in reality. Indeed, the individual in virtual reality is considered as a real individual to whom we removed fundamental features: spatial unity (Leibniz) and temporal identity or sameness (Ricoeur, 1990). In other words, a virtual ...

We say an algebraic object or property over a field k is arithmetic if it becomes trivial or vanishes after finite separable base extension. Since such objects or properties owe their existence to the presence of “arithmetic gaps” in k, i.e., the failure of k to be algebraically closed, we view them as responses to specific arithmetic properties of k, and we study them in order to gain insight ...

1. A function is arithmetic if it is defined on the positive integers. Those arithmetic functions which assume real values and satisfy f(ab)-f(a)+f(b) for mutually prime integers a, b are classically called additive. The following examples illustrate the interest of these functions, both for themselves and for their applications. An additive function is defined by its values on the prime powers...

Facing a second major event of computational linguistics in Prague in the history of Czech CL – the ACL Annual Meeting in June 2007 – we cannot leave the first such event – COLING 1982 – unmentioned. But alas – most unfortunately, we have to start with very sad news about the then President of the Congress, Professor Ján Horecký, who died on August 11th, 2006 in his hometown Stupava (near Brati...
