Large deflections of non-prismatic nonlinearly elastic cantilever beams subjected to non-uniform continuous load and a concentrated load at the free end

引用

Acta Mechanica Sinica 2012年第3期28卷 863-869页

作者： Miha Brojan Matjaz Cebron franc.Kosel Laboratory for Nonlinear Mechanics Faculty of Mechanical EngineeringUniversity of LjubljanaAskerceva 6SI-1000 LjubljanaSlovenia

This work studies large deflections of slen- der, non-prismatic cantilever beams subjected to a combined loading which consists of a non-uniformly distributed con- tinuous load and a concentrated load at the free end of the beam. The material of the cantilever is assumed to be non- linearly elastic. Different nonlinear relations between stress and strain in tensile and compressive domain are considered. The accuracy of numerical solutions is evaluated by com- paring them with results from previous studies and with a laboratory experiment.

Canonical Workflows to Make Data FAIR

引用

Data Intelligence 2022年第2期4卷 286-305页

作者： Peter Wittenburg Alex Hardisty Yann Le franc.Amirpasha Mozaffari Limor Peer Nikolay A.Skvortsov Zhiming Zhao Alessandro Spinuso FDO Forum Cardiff University e Science Factory Forschungszentrum Jülich GmbH Yale University Russian Academy of Sciences University of Amsterdam Royal Netherlands Meteorological Institute (KNMI)

The FAIR principles have been accepted globally as guidelines for improving data-driven science and data management practices, yet the incentives for researchers to change their practices are presently weak. In addition, data-driven science has been slow to embrace workflow technology despite clear evidence of recurring practices. To overcome these challenges, the Canonical Workflow Frameworks for Research(CWFR) initiative suggests a large-scale introduction of self-documenting workflow scripts to automate recurring processes or fragments thereof. This standardised approach, with FAIR Digital Objects as anchors, will be a significant milestone in the transition to FAIR data without adding additional load onto the researchers who stand to benefit most from it. This paper describes the CWFR approach and the activities of the CWFR initiative over the course of the last year or so, highlights several projects that hold promise for the CWFR approaches, including Galaxy, Jupyter Notebook, and RO Crate, and concludes with an assessment of the state of the field and the challenges ahead.

Conservatory of Kaup-Kupershmidt Equation to the Concept of Fractional Derivative with and without Singular Kernel

Acta Mathematicae Applicatae Sinica 2018年第2期34卷 351-361页

作者： Abdon ATANGANA Emile franc.Doungmo GOUFO Institute for Groundwater Studies University of the Free State 9300 Bloemfontein South Africa Department of Mathematical Sciences University of South Africa Florida 0003 South Africa

Making use of the traditional Caputo derivative and the newly introduced Caputo-Fabrizio deriva- tive with fractional order and no singular kernel, we extent the nonlinear Kaup-Kupershmidt to the span of fractional calculus. In the analysis, different methods of fixed-point theorem together with the concept of piccard L-stability are used, allowing us to present the existence and uniqueness of the exact solution to models with both versions of derivatives. Finally, we present techniques to perform some numerical simulations for both non-linear models and graphical simulations are provided for values of the order α = 1.00; 0.90. Solutions are shown to behave similarly to the standard well-known traveling wave solution of Kaup-Kupershmidt equation.

Cerebrospinal fluid neurogranin as a new player in prion disease diagnosis and prognosis

Neurogranin (Ng) and its role as Alzheimer’s disease (AD) biomarker: Ng is a calmodulin-binding protein mainly expressed in cerebral structures such as the cortex,hippocampus and *** is mainly located in the dendritic processes,particularly in post-synaptic compartments,but also in the cytosolic compartment,being likely involved in the regulation of the intracellular calcium-calmodulin signaling pathway (Represa et al.,1990).In the last decade,a plethora of studies have demonstrated that cerebrospinal fluid (CSF) Ng is increased in AD patients and in individuals with an ADlike CSF profile (Kester et al.,2015a).This increase seems to be disease-specific because other neurodegenerative conditions including frontotemporal dementia,Lewy body dementia,Parkinson’s disease,progressive supranuclear palsy,multiple system atrophy or Huntington’s disease,present CSF Ng concentrations similar to controls (Wellington et al.,2016).Ng levels in CSF appear to be elevated in mild cognitive impairment (MCI)-affected individuals who progress to AD and are highly related to memory and cognitive function (Kester et al.,2015a;Tarawneh et al.,2016),which indicates that this protein may serve as an early AD biomarker with diagnostic utility in pre-dementia disease stages,and with prognostic utility to predict cognitive decline and MCI-to-AD conversion.

Natural organic matter quantification in the waters of a semiarid freshwater wetland (Tablas de Daimiel, Spain)

Dissolved organic matter （DOM） concentrations have been measured in the waters of a semiarid freshwater wetland, the Tablas de Daimiel, Spain, when the system-characterised by variable hydroperiodicity conditions, was completely flooded （February 2011）. Fluxes of DOM from the wetland soils to the overlying waters were measured by using a passive diffusion sampler （peeper）. Not only dissolved organic carbon （DOC） concentrations were measured but refractory organic matter （ROM, usually known as humic substances） was also quantified using a novel voltammetric method. Fluorescence spectra were recorded to help in selecting the appropriate standard for ROM quantification, test the homogeneity of DOM in the waters and get an indication of their source. The results obtained show a 7-fold increase in measured ROM concentrations from the Gigtiela River to the outlet, which points to a net exportation of ROM from the wetland and to the existence of an internal source of ROM in the system, probably diffusion from the wetland soils. This hypothesis is confirmed by the flux of ROM from the soils to the water column measured with the peeper and by the common fluorescence characteristics of colunm and interstitial waters. The smaller increase in DOC concentrations along the wetland, in spite of the higher DOC fluxes from soils, suggests that there is significant turnover of organic carbon （OC） in the water column. The system acts as a major carbon sink but, when flooded, exports .OC as DOM.
