PPM compression without escapes
A significant cost in PPM data compression (and often the major cost) is the provision and efficient coding of escapes while building contexts. This paper presents some recent work on eliminating escapes in PPM compression, using bit-wise compression with binary contexts. It shows that PPM without escapes can achieve averages of 2.5 bits per character on the Calgary Corpus and 2.2 bpc on the Ca...
متن کاملStreptococcus pyogenes escapes from autophagy.
Autophagy is important for innate defense against intracellular bacteria, such as Group A Streptococcus (GAS). In this issue of Cell Host & Microbe, Barnett et al. (2013) demonstrate that the globally disseminated serotype M1T1 clone of GAS can evade autophagy via streptococcal cysteine protease SpeB-mediated degradation of ubiquitin-LC3 adaptor proteins.
متن کاملFault Escapes in Duplex Systems
Hardware duplication techniques are widely used for concurrent error detection in dependable systems to ensure high availability and data integrity. These techniques are vulnerable to common-mode failures (CMFs). Use of duplex systems with diverse implementations of the two modules has been proposed in the past for protection against CMFs. In this paper, we define a category of faults, called n...
متن کاملProcessing Escapes: A New Perspective on
Novel approaches in cancer therapy have emerged in recent years. It is well-established that tumors tend to have a different antigenicity than normal cells, thereby triggering an immune response against the tumor, which include the development of tumor specific lymphocytes. One distinct therapeutically approach involves the usage of monoclonal antibodies for immune checkpoint inhibition. CTLA-4...
متن کاملPartial Control of escapes in Chaotic scattering
Chaotic scattering in open Hamiltonian systems is relevant for different problems in physics. Particles in such kind of systems can exhibit both bounded or unbounded motions for which escapes from the scattering region can take place. This paper analyzes how to control the escape of the particles from the scattering region in the presence of noise. For that purpose, we apply the partial control...
