Stagnation Detection with Randomized Local Search [PDF]
Evolutionary Computation, 2021 Recently a mechanism called stagnation detection was proposed that automatically adjusts the mutation rate of evolutionary algorithms when they encounter local optima. The so-called $SD-(1+1)EA$ introduced by Rajabi and Witt (GECCO 2020) adds stagnation detection to the classical $(1+1)EA$ with standard bit mutation, which flips each bit independently ...

Connections between summer air pollution and stagnation
Environmental Research Letters, 2018 The body of literature on ambient air pollution suggests that atmospheric stagnation events trigger high levels of air pollution. In this paper we use fifteen years (2000–2014) of summertime in situ air quality measurements together with meteorological ...

Recognizing early MRI signs (or their absence) is crucial in diagnosing metachromatic leukodystrophy
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1999-2009, December 2022., 2022 Abstract Objectives Metachromatic leukodystrophy (MLD) has characteristic white matter (WM) changes on brain MRI, which often trigger biochemical and genetic confirmation of the diagnosis. In early or pre‐symptomatic disease stages, these typical MRI changes might be absent, hampering early diagnosis.

Economic growth and productivity: Italy and the role of knowledge
PSL Quarterly Review, 2020 The COVID-19 crisis has hit Italy severely: by mid-2020, GDP had returned to the level observed in 1993. This is the result not only of its sharp collapse in the first half of 2020, but also of its weak growth since the 1990s.

Variable Legionella Response to Building Occupancy Patterns and Precautionary Flushing
Microorganisms, 2022 When stay-at-home orders were issued to slow the spread of COVID-19, building occupancy (and water demand) was drastically decreased in many buildings. There was concern that widespread low water demand may cause unprecedented Legionella occurrence and ...

On stagnation of the DGMRES method [PDF]
Iranian Journal of Numerical Analysis and Optimization, 2022 Let $A$ be an $n$-by-$n$ matrix with index $\alpha>0$ and $b \in \mathbb{C}^n$. In this paper, the problem of stagnation of the DGMRES method for the singular linear system $Ax=b$ is considered. We show that DGMRES$(A, b, \alpha)$ has partial stagnation

Considerations for large building water quality after extended stagnation
AWWA Water Science, 2020 The unprecedented number of building closures related to the coronavirus disease (COVID‐19) pandemic is concerning because water stagnation will occur in many buildings that do not have water management plans in place.

Hybrid nanofluid flow towards a stagnation point on a stretching/shrinking cylinder
Scientific Reports, 2020 This paper examines the stagnation point flow towards a stretching/shrinking cylinder in a hybrid nanofluid. Here, copper (Cu) and alumina (Al 2 O 3 ) are considered as the hybrid nanoparticles while water as the base fluid.

THE DYNAMICS OF STAGNATION: A PANEL ANALYSIS OF THE ONSET AND CONTINUATION OF STAGNATION [PDF]
Macroeconomic Dynamics, 2016 This paper analyzes periods of economic stagnation in a panel of countries. We test whether stagnation can be predicted by institutional characteristics and political shocks and compare the impacts of such variables with those of traditional macroeconomic variables.
