Threshold models for the determination of genetic variability among reproductive traits in Nellore cattle [PDF]
Pesquisa Agropecuária Brasileira: The objective of this work was to evaluate the potential of different threshold models to determine the genetic variability in Nellore cattle, with basis on the heritability estimates for the traits stayability (STA) and first calving probability at 36

Effects of type traits, inbreeding, and production on survival in US Jersey cattle
Journal of Dairy Science, 2023 : Greater longevity is associated with lower replacement costs, higher average milk production, and fewer replacement heifers needed. Longevity data are obtained late in life, and for this reason stayability, defined as the probability of survival from ...

Spatial Memory Activity Distributions Indicate the Hippocampus Operates in a Continuous Manner
Brain Sciences, 2016 There is a long-standing debate as to whether recollection is a continuous/graded process or a threshold/all-or-none process. In the current spatial memory functional magnetic resonance imaging (fMRI) study, we examined the hippocampal activity ...

Thresholds models of technological transitions [PDF]
Environmental Innovation and Societal Transitions, 2014 We present a systematic review of seven threshold models of technological transitions from physics, biology, economics and sociology. The very same phenomenon of a technological transition can be explained by very different logics, ranging from economic explanations based on price, performance and increasing returns to alternative explanations based on

Learnability of Competitive Threshold Models
Proceedings of the Thirty-First International Joint Conference on Artificial Intelligence, 2022 Modeling the spread of social contagions is central to various applications in social computing. In this paper, we study the learnability of the competitive threshold model from a theoretical perspective. We demonstrate how competitive threshold models can be seamlessly simulated by artificial neural networks with finite VC dimensions, which enables ...

Technological and Economic Development of EconomyIn the post-pandemic era, the relative weakness of the economy is reflected not only in the macro data but also in the nighttime economy. Based on the threshold model and unbalanced panel data of 1772 county-level administrative units in China from 2014
