A signaling pathway transmits information from an upstream system to downstream systems, ideally in a unidirectional fashion. A key obstacle to unidirectional transmission is retroactivity, the additional reaction flux that affects a system once its species interact with those of downstream systems. This raises the fundamental question of whether signaling pathways have developed specialized ar...

In 1998, Blaze, Bleumer and Strauss introduced a cryptographic primitive called proxy re-encryption (PRE) in which a proxy can transform – without seeing the plaintext – a ciphertext encrypted under one key into an encryption of the same plaintext under another key. The concept has recently drawn renewed interest. Notably, Canetti and Hohenberger showed how to properly define (and realize) chos...

Unidirectional multi-resonant tunneling of the magnetoelectric (ME) field excitations through a subwavelength (regarding the scales of regular electromagnetic radiation) vacuum or isotropicdielectric regions has been observed in two-port microwave structures having a quasi-2D ferrite disk with magnetic dipolar mode (MDM) oscillations. The excitations manifest themselves as Fano-resonance peaks ...

A signaling pathway transmits information from an upstream system to downstream systems, ideally unidirectionally. A key bottleneck to unidirectional transmission is retroactivity, which is the additional reaction flux that affects a system once its species interact with those of downstream systems. This raises the question of whether signaling pathways have developed specialized architectures ...

a major constraint to the application of any form of knowledge and principles is the awareness, understanding and acceptance of the knowledge and principles. systems thinking (st) is a way of understanding and thinking about the nature of  health systems and how to make and implement decisions within health systems to maximize desired and minimize undesired effects. a major constraint to applyi...

Multi-constraint quality-of-service routing will become increasingly important as the Internet evolves to support real-time services. It is well known however, that optimum multi-constraint QoS routing is computationally complex, and for this reason various heuristics have been proposed for routing in practical situations. Among these methods, those that use a single mixed metric are the mo...

Power-supply, a surprisingly simple and new general paradigm for the development of self-stabilizing algorithms in diierent models, is introduced. The paradigm is exempliied by developing simple and eecient self-stabilizing algorithms for leader election and either BFS or DFS spanning tree constructions, in strongly-connected unidirectional and bi-directional dynamic networks (synchronous and a...

This work presents a procedure to transform an isotropic nonlinear and rate-dependent material model into orthotropic. transformation relies on fast computation modifying the inelastic evolution along any desired direction. With this concept, constitutive law of pure isotropic, is fully preserved. paper shows direct application describe response unidirectional (UD) or bidirectional (BD) fiber-r...
