Sooner or later attempts will be made to design systems capable of dealing with a steady flow of sensor data and messages, where actions have to be selected on the basis of multiple, not necessarily consistent, motives, and where new information may require substantial reevaluation of plans and strategies, including suspension of current actions. Where the world is not always friendly, and even...

This paper analyzes the implications of potential offenders caring about their relative status. We establish that subjects’ status concerns can result in multiple-equilibrium crime rates and may modify the standard comparative-statics results regarding how the crime rate changes in response to a higher detection probability and higher sanctions. In addition, we argue that the socially optimal l...

Computational models of motivation are tools that artificial agents can use to identify, prioritize, select and adapt the goals they will pursue autonomously. Previous research has focused on developing computational models of motivation that permit artificial agents to exhibit characteristics such as adaptive exploration, problem-finding behavior, competence-seeking behavior and creativity. Th...

Type-III protein secretion systems are utilized by gram-negative pathogens to secrete building blocks of the bacterial flagellum, virulence effectors from the cytoplasm into host cells, and structural subunits of the needle complex. The flagellar type-III secretion apparatus utilizes both the energy of the proton motive force and ATP hydrolysis to energize substrate unfolding and translocation....

This study analyzes the change of MMORPG in terms of conversion of narrative mode and discusses user identity according to the narrative mode, focused on and . These two games represent the conversion of narrative mode from Romance which has ideal story for it’s main plot, to Irony, which has no background story. This change leads players to have performative persona ...

We introduce the notion of biextensions of 1-motives by 1-motives and we define morphisms from the tensor product of two 1-motives to a third 1-motive as isomorphism classes of such biextensions. If S is the spectrum of a field of characteristic 0, we check that these biextensions define morphisms from the tensor product of the realizations of two 1-motives to the realization of a third 1-motiv...

We prove that under some assumptions on an algebraic group G, indecomposable direct summands of the motive of a projective G-homogeneous variety with coefficients in Fp remain indecomposable if the ring of coefficients is any field of characteristic p. In particular for any projective G-homogeneous variety X, the decomposition of the motive of X in a direct sum of indecomposable motives with co...

The SecY protein of Escherichia coli is an integral membrane component of the protein export apparatus. Suppressor mutations in the secY gene (prlA alleles) have been isolated that restore the secretion of precursor proteins with defective signal sequences. These mutations have never been shown to affect the translocation of wild-type precursor proteins. Here, we report that prlA suppressor mut...
