In this paper, we describe a novel constructive method of proving the Craig interpolation property (CIP) based on cut-free hypersequent calculi and apply the method to prove the CIP for the modal logic S5.

The question of whether the class of decision problems that can be solved by deterministic polynomial-time algorithms (P ) is equal to the class of decision problems that can be solved by nondeterministic polynomial-time algorithms (NP) has been open since it was first formulated by Cook, Karp, and Levin in 1971. In this paper, we prove that they are not equal by showing that any algorithm that...

This study adopts the push-entrepreneurship perspective and develops a conceptual framework grounded in prospect theory, in order to investigate whether source of sunemployment, layoff in particular, and duration of unemployment stimulate entrepreneurial intent. We also propose that fear of failure and risk propensity moderate the source/duration–entrepreneurial intent relationships. We test ou...

Craig C. Mello is an American developmental biologist and Nobel Laureate, who helped discover RNA interference [4] (RNAi). Along with his colleague Andrew Fire [5], he developed gene knockouts using RNAi. In 2006 Mello won the Nobel Prize in Physiology or Medicine [6] for his contribution to the discovery of RNAi. Mello also contributed to developmental biology, focusing on gene regulation [7],...

Stop and go traffic that leads to oscillate traffic flow frequently is observed on congestion flow. Unexpected reasons such as lane – changing maneuvers, lower speeds of leader vehicle and moving bottleneck cause stop and go traffic and amplifying delay and environment impacts. Stop and go traffic exactly can’t be modeled by traffic models, and also car following models based on kinematic flow ...
