An efficient method to remove mixed Gaussian and random-valued impulse noise

Plos.org 

by Mengdi Xing, Guorong Gao

Mixed Gaussian and Random-valued impulse noise (RVIN) removal is still a big challenge in the field of image denoising. Existing denoising algorithms have defects in denoising performance and computational complexity. Based on the improved “detecting then filtering” strategy and the idea of inpainting, this paper proposes an efficient method to remove mixed Gaussian and RVIN. The proposed algorithm contains two phases: noise classification and noise removal. The... Читать дальше...

Joint optimization of high-speed train timetables, speed levels and stop plans for increasing capacity based on a compressed multilayer space-time network

Plos.org 

by Angyang Chen, Xingchen Zhang, Junhua Chen, Zhimei Wang

With the steady increase in passenger volume of high-speed railways in China, some high-speed railway sections have faced a difficult situation. To provide more transport services, it is necessary to add as many trains as possible in a section to increase capacity. To solve this problem, a compressed multilayer space-time network model is constructed with the maximum number of trains that can be scheduled in the train timetable as the objective.

“The stress can be unbearable, but the good times are like finding gold”: A phase one modelling survey to inform the development of a self-help positive reappraisal coping intervention for caregivers of those with autism spectrum disorder

Plos.org 

by Deborah Lancastle, Joanna Hill, Susan Faulkner, Alecia L. Cousins

Caregivers of individuals with ASD can experience various practical, psychological, and social demands and need effective ways of coping to ameliorate the negative effects of caregiving. Numerous coping strategies are available, but the literature shows that caregivers can still struggle to cope, suggesting that interventions to support coping efforts could be beneficial. The MRC framework advocates the systematic development and evaluation of interventions... Читать дальше...

Science, technology, and innovation policy timing and nanotechnology entrepreneurship and innovation

Plos.org 

by Jennifer L. Woolley, Nydia MacGregor

The timing of science, technology, and innovation (STI) policy initiatives is critical to the outcomes that they produce. This study examines the advantages and disadvantages of enacting STI policy investments early in a nascent domain of activity. Building on work across multiple disciplines, we propose a framework to better understand the temporal dynamics of STI policy. An examination of data on nanotechnology STI policy around the world shows that... Читать дальше...

Dental caries and associated factors among patients visiting Shashamane Comprehensive Specialized Hospital

Plos.org 

by Aliye Geleto, Edao Sinba, Musa Mohammed Ali

Introduction

Dental caries is a major public health problem. In Ethiopia, prevention and treatment of oral health-related illness had given little attention and there is limited data on the extent and factors associated with oral health-related illnesses and oral care practices.

Objective

This study was aimed to investigate the prevalence of dental caries and associated factors among patients visiting Shashamane Comprehensive Specialized Hospital (SCSH). Читать дальше...

Ethylenediaminetetraacetate functionalized MgFe layered double hydroxide/biochar composites for highly efficient adsorptive removal of lead ions from aqueous solutions

Plos.org 

by M. T. Amin, A. A. Alazba, M. Shafiq

The application of layered double hydroxides (LDHs) of MgFe and its composites with biochar of Eucalyptus camdulensis (Eb) and ethylenediaminetetraacetic acid (EDTA) was explored in a batch study to mitigate toxic lead ions (Pb2+) from synthetic wastewater solutions. SEM images revealed that MgFe/LDH composites with Eb were successfully formed, while FTIR spectra confirmed the successful adsorption of Pb2+ onto the MgFe/LDH and composite adsorbents. Batch equilibrium was attained after 60 min... Читать дальше...

Human rights as a framework for eliminating female genital schistosomiasis

Plos.org 

by Caitlin R. Williams, Maximillian Seunik, Benjamin Mason Meier

Female genital schistosomiasis (FGS) affects tens of millions of women and girls in sub-Saharan Africa, yet this inequitable threat is often overlooked by advocates in both the neglected tropical disease (NTD) and sexual and reproductive health and rights (SRHR) communities. FGS causes both acute infection and long-term sexual and reproductive health harm to marginalized women and girls, with gender, poverty, and rurality combining to invisibilize the disease.

Conceptual model of low-cost improvised bubble continuous positive airway pressure device for adults and its potential use in the COVID-19 pandemic

Plos.org 

by Himal Kharel, Zeni Kharel, Samikchhya Keshary Bhandari

Low-cost improvised continuous positive airway pressure (CPAP) device is safe and efficacious in neonatal respiratory distress. There is a great necessity for similar device in adults, and this has been especially made apparent by the recent Coronavirus Disease 2019 (COVID-19) pandemic, which is unmasking the deficiencies of healthcare system in several low-resource countries. We propose a simplified and inexpensive model of improvised... Читать дальше...

Co-transmission of neuropeptides and monoamines choreograph the C. elegans escape response

Plos.org 

by Jeremy T. Florman, Mark J. Alkema

Co-localization and co-transmission of neurotransmitters and neuropeptides is a core property of neural signaling across species. While co-transmission can increase the flexibility of cellular communication, understanding the functional impact on neural dynamics and behavior remains a major challenge. Here we examine the role of neuropeptide/monoamine co-transmission in the orchestration of the C. elegans escape response. The tyraminergic RIM neurons,... Читать дальше...
