Conventional aquaculture (ACUA-C) in Mexico is an activity that maintains annual growth rate of 6%. Tilapia (Oreochromis niloticus) the predominant country with 4623 farms, most which operate semi-intensive (SIS) and extensive (ES) production systems, discharging untreated wastewater negatively impacts environment. To address this problem, new ecotechnologies such as biofloc (BFT), recirculatio...

Ceramic materials have many striking prospects as temperature sensors. Still, some inevitable shortcomings comprising toxicity, low biocompatibility, extensive response well recovery times, poor sensitivity, and hysteresis obstruct them from various progressive uses. Therefore, in this current exploration, a capacitive sensor has been designed developed using lead-free ferroelectric ceramic Bi(...

This paper argues for a new approach to building Byzantine fault tolerant systems. We observe that although recently developed BFT state machine replication protocols are quite fast, they don’t actually tolerate Byzantine faults very well: a single faulty client or server is capable of rendering PBFT, Q/U, HQ, and Zyzzyva virtually unusable. In this paper, we (1) demonstrate that existing proto...

Fault-tolerant consensus has been studied extensively in the literature, because it is one of the most important distributed primitives and has wide applications in practice. This paper surveys important results on fault-tolerant consensus in message-passing networks, and the focus is on results from the past decade. Particularly, we categorize the results into two groups: new problem formulati...

Data were recorded in two lines divergently selected for residual feed intake (RFI) for eight generations (G0 to G7). First, an animal mixed model was applied to the full dataset to estimate least square means (LsCG) of contemporary group (CG) effects for average daily gain (ADG, 3189 pigs, 80 CG) and backfat thickness (BFT, 1668 pigs, 44 CG). Second, LsCG were used as covariates in linear mode...

We quantize the spontaneously broken abelian U(1) Higgs model by using the improved BFT and BFV formalisms. We have constructed the BFT physical fields, and obtain the first class observables including the Hamiltonian in terms of these fields. We have also explicitly shown that there are exact form invariances between the second class and first class quantities. Then, according to the BFV forma...

The surprising success of cryptocurrencies has led to a surge of interest in deploying large scale, highly robust, Byzantine fault tolerant (BFT) protocols for mission-critical applications, such as financial transactions. Although the conventional wisdom is to build atop a (weakly) synchronous protocol such as PBFT (or a variation thereof), such protocols rely critically on network timing assu...

We describe a protocol called ‘Hot-Stuff the Linear, Optimal-Resilience, One-Message BFT Devil’ (in short, Hot-Stuff) for n = 3f+1 replicas, of which 2f+1 are honest, to agree on a replicated, ever-changing state. The protocol is always safe against a threshold f of Byzantine failures, even when the system is asynchronous. Progress is guaranteed under periods of synchrony. The per-round communi...

Quorum-based Byzantine fault-tolerant protocols for replicated state machines allow replicas to respond to client requests without explicitly agreeing on the request ordering. As long as concurrent write operations do not conflict, quorum-based protocols are more efficient than agreement-based protocols. However, resolving conflicting writes and bringing replicas up-to-date with each other is a...
