Much recent work on Byzantine state machine replication focuses on protocols with improved performance under benign conditions (LANs, homogeneous replicas, limited crash faults), with relatively little evaluation under typical, practical conditions (WAN delays, packet loss, transient disconnection, shared resources). This makes it difficult for system designers to choose the appropriate protoco...

Abstract Provision of suitable technique for saline tilapia seed is required since demand these species increased continuously. Most rely on sourcing freshwater fingerling and further acclimatized in brackishwater ponds. The study aimed to evaluate the effects various fry densities production parameters under high salinity-biofloc system. Three being tested cultured biofloc technology (BFT) at ...

After the Practical Byzantine Fault Tolerance work [2], the distributed systems literature has improved quality and performance of *BFT systems. Through this definition we address all the solutions, deriving from [2], for State Machine Replication (SMR) that are based on node active replication (usally 3f+1 replicas for f faults), and where servers are always synchronized on the set of operatio...

Thiamine (vitamin B1) is essential for brain function because of the coenzyme role thiamine diphosphate (ThDP) in glucose and energy metabolism. In order to compensate deficiency, several precursors with higher bioavailability were developed since 1950s. Among these, thioester benfotiamine (BFT) has been extensively studied beneficial effects both rodent models neurodegeneration human clinical ...

We present Cobalt, a novel atomic broadcast algorithm that works in networks with non-uniform trust and no global agreement on participants, and is probabilistically guaranteed to make forward progress even in the presence of maximal faults and arbitrary asynchrony. The exact properties that Cobalt satisfies makes it particularly applicable to designing an efficient decentralized"voting network...

In the race for Gigabit wireless links, IEEE introduced 802.11ad, an amendment aimed at delivering Gbps capacities in a WLAN setting by leveraging 60 GHz band. The key innovation of standard is its beamforming training protocol. Executed periodically beginning every beacon interval, it enables formation directional links. To address contention during uplink part training, 802.11ad A-BFT (Associ...

Byzantine faults in a peer-to-peer (P2P) system are resulted from adversarial and inconsistent peer behaviors. Malicious peers can disrupt the routing functions in peer joining and lookup services. Byzantine attackers may collude with each other to paralyze the entire P2P network operations. We discover a new class of DHT-based overlay networks, called inverse de Bruijn (IDB) graph, to enable m...

AIMS To introduce new terminology and validate its reliability for the analysis of optical coherence tomography (OCT) scans, compare clinical detection of cystoid macular oedema (CMO) and subretinal fluid (SRF) with OCT findings, and to study the effect of photodynamic therapy (PDT) on the foveal morphology. METHODS Patients with subfoveal, predominantly classic choroidal neovascularisation (...
