Flocks participating in sire referencing schemes can achieve greater genetic gains than those achievable by within-flock selection. However, requirements for joining these schemes can be prohibitive to some producers. The objectives of this study were to determine whether less restrictive schemes or schemes of shorter duration could achieve rates of gain and reduce inbreeding as efficiently as ...

While holding great development opportunities to be seized, Africa has been identified as particularly vulnerable to climate changes, and the ZRB is no exception to that. With increasing demands to the Zambezi system in terms or water and energy, and rising challenges in the form of less runoff due to climate change, it is paramount to plan ahead. In particular, it must be understood how major ...

T the ripe age of eighty-four Lloyd Morgan has passed away. jje wag for many years the distinguished and greatlyeloved Principal of University College, and when the College deceived its charter in 1909 converting it into Bristol diversity Lloyd Morgan was designated the first Vicehancellor. He relinquished this office almost immediately, nd Sir Igambard Owen was appointed in his stead. His ecis...

The Agricultural Policy Environmental eXtender (APEX) model is capable of estimating edge-of-field water, nutrient, and sediment transport and is used to assess the environmental impacts of management practices. The current practice is to fully calibrate the model for each site simulation, a task that requires resources and data not always available. The objective of this study was to compare m...

Using the most recent atmospheric neutrino data, as well as short-baseline, longbaseline and tritium β-decay data we show that the joint interpretation of the LSND, solar and atmospheric neutrino anomalies in (3+1) sterile neutrino schemes is severely disfavored, in contrast to the theoretically favored (2+2) schemes.

The aphorism “All models are wrong but some are useful” (Box, 1978) sums up much of what ML is about. The assumptions we make in the Naive Bayes approach to sentimanet classification are wrong, but this is true of the assumptions made in all current formal models of human language (statistical or otherwise), with the possible exception of a few which are very restricted indeed. However, the que...

A group of web-server system can be deployed to support high request rate. The Domain Name System (DNS) servers act as a mediator between the client and web-servers. It dispatches the client request among the web-servers through the URL-name to IP-address mapping mechanism. In this paper, we propose a group of web-server system arranged in the multiple logical ring connection, in which the DNS ...

This paper describes a timeline-based, domain independent deliberative layer, based on ESA APSI technology, deployed in the context of the Goal Oriented Autonomous Controller (GOAC) project. In particular the paper describes a new controller composed by (1) a planning module that exploits the timeline-based approach provided by the APSI-TRF and is able to model and solve planning problems, (2) ...
