Plasmodium of Physarum polycephalum is a single cell visible by unaided eye. On a non-nutrient substrate the plasmodium propagates as a traveling localization, as a compact wave-fragment of protoplasm. The plasmodium-localization travels in its originally predetermined direction for a substantial period of time even when no gradient of chemo-attractants is present. We utilize this property of P...

Commutativity of subsystems in cascade connected forms to form larger systems gets worthy to improve noise disturbance properties, stability, robustness and many other properties in system design. In this paper, another benefit of commutativity property is indicated, as far as the author knowledge for the first time, and illustrated by examples. This benefit is the gain of a new and original me...

We introduce the notion of Cross-Unlinkability for group signature schemes. Considering groups organized in a tree structure, where belonging to the parent group is required to join a new group, CrossUnlinkability enables a cascade revocation process that takes into account the underlying tree structure, while ensuring anonymity for nonrevoked users, in particular, towards the managers of the o...

This paper presents a generalization of the chain-scattering representation to the case of general plants. Through the notion of input-output consistency, the conditions under which the generalised chain-scattering representation (GCSR) and the dual generalised chain-scattering representation (DGCSR) exist are proposed. The generalised chainscattering matrices are formulated into a general para...

This paper investigates wave-based analysis and impedance matching for the ladder electric networks. The results are a generalized version of our previous work for the cascade connected damped mass-spring systems. We first clarify the class of the ladder networks which satisfies the three conditions for the propagation constants to be analyzed by the wave-based analysis. Secondly, for the class...

INTRODUCTION Environmental factors can play a role in the pathogenesis of Alzheimer's disease. We present a case of the simultaneous onset of Alzheimer's disease in two middle aged adults. CASE PRESENTATION A married couple ages 54 year and 51-year-old female cohabiting together were diagnosed with Alzheimer's disease within the same year. The patient's both developed cognitive decline shortl...

Structural controllability, which is an interesting property of complex networks, attracts many researchers from various fields. The maximum matching algorithm was recently applied to explore the minimum number of driver nodes, where control signals are injected, for controlling the whole network. Here we study the controllability of directed Erdös–Rényi and scale-free networks under attacks an...

Pomaranch is a synchronous, hardware-oriented stream cipher submitted to eSTREAM, the ECRYPT Stream Cipher Project. The cipher is designed as a cascade clock-controlled key-stream generator built on jump registers. This paper presents a discussion over the attacks on Pomaranch discovered so far. Particular focus is made on a new inherent property of jump registers that allows to construct their...

Within a covariant parton cascade, we discuss the impact of both finite shear viscosity η and freeze-out dynamics on the elliptic flow generated at RHIC. We find that the enhancement of η/s in the cross-over region of the QGP phase transition cannot be neglected in order to extract the information from the QGP phase. We also point out that the elliptic flow v2(pT ) for a fluid at η/s ∼ 0.1− 0.2...

We consider a linear threshold model of cascades in networks. An agent switches (e.g. adopts an innovation) if the proportion of his neighbors who have already switched exceeds his threshold. Agents’ thresholds are drawn randomly at the start of the cascade process. We present a result for the expected number of switches in arbitrary finite networks with any initial seeds. We define a new measu...
