In this paper we study the relations between superadditivity and several types of convexity for cooperative games with random payoffs. The types of convexity considered are marginal convexity (all marginal vectors belong to the core), individual-merge convexity (any individual player is better off joining a larger coalition) and coalitional-merge convexity (any coalition of players is better of...

We consider two-way continuous-variable quantum key distribution, studying its security against general eavesdropping strategies. Assuming the asymptotic limit of many signals exchanged, we prove that two-way Gaussian protocols are immune to coherent attacks. More precisely we show the general superadditivity of the two-way security thresholds, which are proven to be higher than the correspondi...

The occipital and parietal lobes contain regions that are recruited for both visual and haptic object processing. The purpose of the present study was to characterize the underlying neural mechanisms for bimodal integration of vision and haptics in these visuo-haptic object-selective brain regions to find out whether these brain regions are sites of neuronal or areal convergence. Our sensory co...

1. UNDERSTANDING THE TERMS OF THE DEBATE. In their response to our article (Sprouse et al. 2012), Hofmeister, Staum Casasanto, and Sag (2012, henceforth HSS) level three primary criticisms at our studies: (i) that working-memory (WM) correlations are not predicted by reductionist theories, (ii) that theWM tasks that we chose are inappropriate for showing the predicted correlation, and (iii) tha...

The hypothesis that category descriptions are interpreted narrowly, in terms of representative instances, is examined by comparing probability judgments for packed descriptions of events to judgments for coextensional unpacked descriptions. The representativeness of the unpacked instance was varied along with the type of unpacking (direct vs. priming). In contrast to the prediction of Support T...

The coalition formation is an important aspect of multi-agent negotiation and cooperation. Based on the Bilateral Shapley-Value, a multi-sided eigenvalue is presented by using the reference of n-person stochastic cooperative game. It is obvious when multisided eigenvalue have superadditivity, rational agents will combine to one coalition. A dynamic coalition formation algorithm is constructed b...

Many types of insurance premium principles and/or risk measures can be characterized by means of a set of axioms, which in many cases are rather arbitrarily chosen and not always in accordance with economic reality. In the present paper we generalize Yaari’s risk measure by relaxing his axioms. In addition, we derive translation invariant minimal Orlicz risk measures, which we call Haezendonck ...

In this article, we investigate the additivity phenomenon in the dynamic capacity of a quantum channel for trading classical communication, quantum communication and entanglement. Understanding such additivity property is important if we want to optimally use a quantum channel for general communication purpose. However, in a lot of cases, the channel one will be using only has an additive singl...
