Nonlinear Autoregressive Neural Network for Antimicrobial Waste Water Treatment

open access: yesAdsorption Science & Technology, 2022
Antibiotics become an emerging contaminant and receive more interests due to its ecotoxicological and strong stability in water ecosystems. Antibiotic adsorption onto carbon materials are biochars among the wastewater mechanisms.

Fourier transform infrared cell for surface studies at controlled temperatures and in controlled atmospheres with time resolution and spatial resolution [PDF]

open access: yes, 1996
A new micro-Fourier transform infrared cell has been constructed and evaluated using (i) the transformation of aurichalcite crystals at 298-475 K, (ii) the adsorption/desorption of pyridine on a Cu2O/ZnO junction, and (iii) the adsorption of CO on Pt ...

Expanded Parameters in the Self-Organized Critical Forest Fire Model [PDF]

open access: yes, 2016
The forest fire model has frequently been used as a way to test the theory of Self-Organized Criticality, which is a model of complexity. The model analyzes commonalities in randomly generated forest fires using a computer simulation. In previous models,

New 40Ar/39Ar dating of the Grande Ronde lavas, Columbia River Basalts, USA: Implications for duration of flood basalt eruption episodes [PDF]

open access: yes, 2010
Grande Ronde Basalt (GRB) lavas represent the most voluminous eruptive pulse of the Columbia River-Snake River-Yellowstone hotspot volcanism. With an estimated eruptive volume of 150,000 km3, GRB lavas form at least 66% of the total volume of the ...

Digital biomarkers for early agitation detection in dementia: a scoping review of emerging wearable and smart technologies for personalized care

open access: yesFrontiers in Neurology
IntroductionAgitation is a common and burdensome symptom in people with dementia, particularly when compounded by impaired communication, making early detection and effective management difficult. Wearable sensor technologies may offer a promising avenue

Oscillatory rheotaxis of artificial swimmers in microchannels

open access: yesNature Communications, 2022
Biological and artificial microswimmers often navigate channels under external flow, where in many biomicroswimmers the active upstream motion is oscillatory. Here the authors demonstrate that regular, controllable, and reproducible oscillatory rheotaxis

The statistical geometry of material loops in turbulence

open access: yesNature Communications, 2022
Turbulent flows are observed in atmosphere, ocean, and technology, with turbulent mixing due to stretching and folding of material elements. The authors analyze a geometric perspective of this process and uncover statistical properties of an ensemble of ...

An exactly solvable self-convolutive recurrence [PDF]

open access: yes, 2010
We consider a self-convolutive recurrence whose solution is the sequence of coefficients in the asymptotic expansion of the logarithmic derivative of the confluent hypergeometic function $U(a,b,z)$. By application of the Hilbert transform we convert this

Discursive framework for a multi-disease digital health passport in Africa: a perspective

open access: yesGlobalization and Health
Africa’s dual burden of rising incidence of infectious diseases and increasing prevalence of non-communicable diseases (NCDs), such as cardiovascular diseases and diabetes, demands innovative approaches to disease surveillance, response, and cross-border
