Resilience and Regime Shifts: Assessing Cascading Effects
Ecology and Society, 2006 Most accounts of thresholds between alternate regimes involve a single, dominant shift defined by one, often slowly changing variable in an ecosystem.

EURASIP Journal on Wireless Communications and Networking, 2010 This paper investigates a wireless cooperative relay network with multiple relays communicating with the destination over orthogonal channels. Proposed is a cooperative transmission scheme that employs two signal-to-noise ratio (SNR) thresholds and ...

Nonparametric regression with multiple thresholds: Estimation and inference [PDF]
Journal of Econometrics, 2018 This paper examines nonparametric regression with an exogenous threshold variable, allowing for an unknown number of thresholds. Given the number of thresholds and corresponding threshold values, we first establish the asymptotic properties of the local constant estimator for a nonparametric regression with multiple thresholds.

Multiple Reject Thresholds for Improving Classification Reliability [PDF]
, 2000 In pattern recognition systems, Chow's rule is commonly used to reach a trade-off between error and reject probabilities. In this paper, we investigate the effects of estimate errors affecting the a posteriori probabilities on the optimality of Chow's rule.

Multiple Benefit Thresholds Problem in Online Social Networks: An Algorithmic Approach
Mathematics, 2022 An important problem in the context of viral marketing in social networks is the Influence Threshold (IT) problem, which aims at finding some users (referred to as a seed set) to begin the process of disseminating their product’s information so that the ...

IEEE Access, 2018 High average-utility itemsets mining (HAUIM) is an emerging topic in data mining. Compared to traditional high utility itemset mining, HAUIM more fairly measures the utility of itemsets by considering their lengths (number of items).

Advanced FDSOI Device Design: The U-Channel Device for 7 nm Node and Beyond
IEEE Journal of the Electron Devices Society, 2018 In this paper, we propose the extendibility of ultra-thin body and box (UTBB) devices to 7 and 5 nm technology nodes focusing on electrostatics. A difficulty in scaling traditional UTBB is the need for SOI scaling to about one fourth of the gate length ...

Targets for maintenance of dead wood for biodiversity conservation based on extinction thresholds [PDF]
, 2006 Forestry decreases the amount of dead wood, thereby threatening the persistence of many saproxylic (wood-living) organisms. In this article, we discuss how targets for efforts to maintain and restore dead wood in managed forest landscapes should be ...
