A new approach for SPN removal: nearest value based mean filter [PDF]

open access: yesPeerJ Computer Science, 2022
In this study, a new adaptive filter is proposed to eliminate salt and pepper noise (SPN). The basis of the proposed method consists of two-stages. (1) Changing the noisy pixel value with the closest pixel value or assigning their average to the noisy ...

Value of Adaptive Trials and Surrogate Endpoints for Clinical Decision-Making in Rare Cancers

open access: yesFrontiers in Oncology, 2021
Despite high-level endorsement, the number of adaptive Phase II/III trials in rare cancers needs to be improved, with better understanding of their value for clinical decisions in daily practice.

Quaternion-Valued Nonlinear Adaptive Filtering [PDF]

open access: yesIEEE Transactions on Neural Networks, 2011
A class of nonlinear quaternion-valued adaptive filtering algorithms is proposed based on locally analytic nonlinear activation functions. To circumvent the stringent standard analyticity conditions which are prohibitive to the development of nonlinear adaptive quaternion-valued estimation models, we use the fact that stochastic gradient learning ...

The Role of Learning on Insect and Spider Sexual Behaviors, Sexual Trait Evolution, and Speciation

open access: yesFrontiers in Ecology and Evolution, 2019
We review experimental and theoretical evidence that learning in insects and spiders affects the expression of mate preferences and of sexual signals, the evolution of both traits, and ultimately patterns of assortative mating, and speciation. Both males

The Adaptive Value of Numerical Competence [PDF]

open access: yesTrends in Ecology & Evolution, 2020
Evolution selects for traits that are of adaptive value and increase the fitness of an individual or population. Numerical competence, the ability to estimate and process the number of objects and events, is a cognitive capacity that also influences an individual's survival and reproduction success. Numerical assessments are ubiquitous in a broad range

Quantum-enhanced mean value estimation via adaptive measurement [PDF]

open access: yesQuantum
Quantum-enhanced (i.e., higher performance by quantum effects than any classical methods) mean value estimation of observables is a fundamental task in various quantum technologies; in particular, it is an essential subroutine in quantum computing ...

Adaptive Tolerant State Estimation under Model Uncertainty in Power Systems

open access: yesEnergies, 2021
In this paper an adaptive tolerant estimator using singular value decomposition is proposed for a distribution network under model uncertainty in power systems. The adaptive tolerant estimator was designed with adjusted parameters and adjusted weights to

Correlational patterns of species diversity, swimming ability and ecological tolerance of non-marine ostracoda (Crustacea) with different reproductive modes in shallow water bodies of ağrı region (Turkey)

open access: yesJournal of Freshwater Ecology, 2019
A total of 52 ostracod taxa (35 live spp. 17 subfossils) were collected from 70 shallow aquatic bodies with 11 different habitat types in Ağrı province (Turkey). Fabaeformiscandona acuminata is a new record for the Turkish ostracod fauna while 29 species
