22 The Staphylococcus aureus cid and lrg operons have been shown to control cell death 23 and lysis in a manner thought to be analogous to programmed cell death (apoptosis) in 24 eukaryotic organisms. Although orthologous operons are present in a wide variety of bacterial 25 species, members of the Bacillus cereus group are unique in that they have a total of four cid-26 /lrg-like operons. Two ...

This paper presents a policy-based framework for managing access control in distributed heterogeneous systems. This framework is based on the PDP/PEP approach. The PDP (Policy Decision Point) is a network policy server responsible for supplying policy information for network devices and applications. The PEP (Policy Enforcement Point) is the policy client (usually, a component of the network de...

With the growing trend toward using outsourced storage, the problem of efficiently checking and proving data integrity needs more consideration. Starting with PDP and POR schemes in 2007, many cryptography and security researchers have addressed the problem. After the first solutions for static data, dynamic versions were developed (e.g., DPDP). Researchers also considered distributed versions ...

A programmed algorithm is presented for the synthesis and optimisation of networks implemented with multiplexer universal logic modules. The algorithm attempts level by level optimisation selecting the control variables that result in minimum number of continuing branches. Cascaded networks, if realisable, are always found and given preference over tree networks, though mixtures of cascade and ...

An unusual case of atrioventricular nodal reentrant tachycardia precipitated by ethanol ingestion is presented. Programmed atrial and ventricular stimulation failed to induce the tachycardia during control conditions or after atropine administration. This failure to induce tachycardia was related to the absence of ventriculoatrial conduction. A low-dose isoproterenol infusion allowed induction ...

Programmed cell death is a highly regulated form of cell death, mostly distinguished by the activation of a family of cystein-aspartate proteases (caspases) that cleave various proteins resulting in morphological and biochemical changes characteristic of this form of cell death. Several recent studies have addressed the role of programmed cell death in inflammatory and chronic pain states. Casp...

wheat is one of the most important crops in the world that is constantly faced with the different biotic and abiotic stresses. programmed cell death is one of the methods for coping with different stress which is stimulated by several factors. because salicylic acid is involved in resistance to various stresses, to explore the effects of salicylic acid on programmed cell death, the effects of s...

We propose an approach to the synthesis of hierarchical control systems comprising both evolved and manually programmed control for autonomous robots. We recursively divide the goal task into subtasks until a solution can be evolved or until a solution can easily be programmed by hand. Hierarchical composition of behavior allows us to overcome the fundamental challenges that typically prevent e...

Programmed cell death is an important process during the development and life of multicellular organisms. The process by which many cell types undergo programmed cell death is morphologically and mechanistically similar and has been termed apoptosis. To understand how cells achieve this conserved cell-death fate, we have analyzed the genetic control of downstream events in the cell-death proces...
