Trypanosoma cruzi metacyclic trypomastigotes (MT), but not blood form trypomastigotes (BFT), are highly mucosally infective. We investigated the abilities of MT and BFT to induce inflammation and/or intracellular killing activity within mucosal epithelia. BFT, but not MT, induced marked increases in interleukin-8, GRO-alpha, MCP-1, and nitric oxide production in HeLa and AGS cells, despite simi...

This study was carried out to identify SNP associated with fatness traits on pig chromosome 6. In total, 11,067 putative genomic variations were detected in 125 complete bacterial artificial chromosome sequences corresponding to the region between SW2098 and SW1881, which harbors multiple QTL affecting intramuscular fat content (IMF) and backfat thickness (BFT). Among 173 putative SNP validated...

To pave the way for Byzantine fault-tolerant (BFT) systems that can exploit the potential of modern multi-core platforms, we present a new parallelization scheme enabling BFT systems to scale with the number of available cores and to provide the performance required by critical central services. The main idea is to organize parallelism around complete instances of the underlying multi-phase BFT...

State-of-the-art BFT protocols remain far from the maximum theoretical throughput. Based on exhaustive evaluation and monitoring of existing BFT protocols, we highlight few impediments to their scaling. These include the use of IP multicast, the presence of bottlenecks due to asymmetric replica processing, and an unbalanced network bandwidth utilization. To better evaluate the actual impact of ...

the bft approach is used to formulate the electronic states in graphene through a non-commutative space in the presence of a constant magnetic field b for the first time. in this regard, we introduce a second class of constrained system, which is not gauge symmetric but by applying bft method and extending phase space, the second class constraints  converts  to the first class constraints so th...

Colonic carriage of enterotoxigenic Bacteroides fragilis (ETBF) is reportedly more common in people presenting with colorectal cancer (CRC) than in healthy controls (1–3), fueling speculation that persistent carriage of these bacteria may “drive” colon carcinogenesis (4). Our aim was to use a bft amplification protocol to determine the prevalence of toxin-producing strains of B. fragilis in CRC...

There are currently two approaches to providing Byzantine-fault-tolerant state machine replication: a replica-based approach, e.g., BFT, that uses communication between replicas to agree on a proposed ordering of requests, and a quorum-based approach, such as Q/U, in which clients contact replicas directly to optimistically execute operations. Both approaches have shortcomings: the quadratic co...

Biorthogonal Fourier transform (BFT), consistent with the matched signal transform (MST), has been introduced to demodulate the M-ray chirp-rate signal which possesses good orthogonality in the BFT domain. Here, we analyze the characteristics of BFT detection in a further step, including the resolution capability of the multichirp-rate signal, the property of pulse compression, the closed-form ...

Many Web services are expected to run with high degree of security and dependability. To achieve this goal, it is essential to use a Web-services compatible framework that tolerates not only crash faults, but Byzantine faults as well, due to the untrusted communication environment in which the Web services operate. In this paper, we describe the design and implementation of such a framework, ca...
