Gentzen’s sequent calculus for classical logic shows great symmetry: for example, the rule introducing ∧ on the left of a sequent is mirror symmetric to the introduction rule for the dual operator ∨ on the right of a sequent. A consequence of this casual observation is that when Γ ` ∆ is a theorem over operators {∨,∧,¬}, then so is ∆ ` Γ, where Σ reverses the order of formulas in Σ, and exchang...

despite several calls to support evidence-informed policy-making, variations in uptake of evidence into policy persist. this editorial brings together and builds on previous knowledge translation (kt) frameworks and theories to present a simple, yet, holistic approach for promoting evidence-informed policies. the proposed conceptual framework is characterized by its impact-oriented approach and...

Tail calls are expected not to consume stack space in most functional languages. However, there is no support for tail calls in some environments. Even in such environments, proper tail calls can be implemented with a technique called a trampoline. To reduce the overhead of trampolining while preserving stack space asymptotically we propose selective tail call elimination based on an effect sys...

Background: This study aims to evaluate the negative health impacts of exposure to electromagnetic field and to prepare a risk map of two selected call centers. Materials and Methods: Two call centers whose electromagnetic field values were measured by calibrated low high and point frequency measurement device. The measurements were performed by following the EN 50492 Standards. 178 employees ...
