In this paper, a new 3-RPS/US parallel mechanism with two degrees of freedom (DOFs) is obtained by adding a US (Universal joint and Spherical joint) passive limb into the 3-RPS (the limb consisting of one revolute, one prismatic, and one spherical joint) parallel mechanism with the aim of obtaining a high load-bearing capacity. The moving platform...

Classification of remote sensing (RS) imagery has been a primary source for mapping applications. Many classification algorithms have been developed in the past four decades to aid this purpose. Most of these classifiers are designed to operate on a single source of data and therefore, fail to operate on multi-source information. An expert system c...

Theoretical models have informed the understanding of pregnancy as a ‘teachable moment’ for health behaviour change. However, these models have not been developed specifically for, nor widely tested, in this population. Currently, no pregnancy-specific model of behaviour change exists, which is important given it is a unique yet common h...

The universal dihydrouridine (D) epitranscriptomic mark results from a reduction of uridine by the Dus family of NADPH-dependent reductases and is typically found within the eponym D-loop of tRNAs. Despite its apparent simplicity, D is structurally unique, with the potential to deeply affect the RNA backbone and many, if not all, RNA-connected proc...

In this article, we conceive the notion of a generalized (α, ψ, q)-Meir-Keeler contractive mapping and then we investigate a fixed point theorem involving such kind of contractions in the setting of a complete metric space via a w-distance. Our obtained result extends and generalizes some of the previously derived fixed point theorems in the litera...

A domain decomposition technique combined with an enhanced geometry mapping based on the use of NURBS is considered for solving parametrized models in complex geometries (non simply connected) within the so-called proper generalized decomposition (PGD) framework, enabling the expression of the solution in each subdomain in a fully separated form, i...

We present imaging techniques in Mössbauer spectroscopy for an operando measurement of pattern formation in materials, i.e., (1) mapping by focused γ-ray and (2) direct imaging by a CMOS camera combining with the mapping system after converting γ-rays to visible light with a scintillator. From the viewpoint of image processing, mapping interval and...

Result
Some fixed point results are found for a sel...

The performance of next-generation, nanoelectronic devices relies on a precise understanding of strain within the constituent materials. However, the increased flexibility inherent to these three-dimensional device geometries necessitates direct measurement of their deformation. Here we report synchrotron x-ray diffraction-based non-destructive nan...

While children are able to name letters fairly quickly, the automatisation of letter-speech sound mappings continues over the first years of reading development. In the current longitudinal fMRI study, we explored developmental changes in cortical responses to letters and speech sounds across 3 yearly measurements in a sample of 18 8–11 year old ch...

Background
Health information (HI) strategies exist in several EU Member States, however, they mainly focus on technical issues and improving governance rather than on content-related priority setting. There is also little research available about national prioritization processes underlying HI development for policy support in the EU. The aim of t...

Background
Research networks offer multidisciplinary expertise and promote information exchange between researchers across Europe. They are essential for the European Union’s (EU) health information system as providers of health information and data.

Significant pressure/force responses were achi...

Background
Fast and accurate T 1ρ mapping in myocardium is still a major challenge, particularly in small animal models. The complex sequence design owing to electrocardiogram and respiratory gating leads to quantification errors in in vivo experiments, due to variations of the T 1ρ relaxation pathway. In this study, we present an improved quantifi...

Recent advances in the field of network representation learning are mostly attributed to the application of the skip-gram model in the context of graphs. State-of-the-art analogs of skip-gram model in graphs define a notion of neighborhood and aim to find the vector representation for a node, which maximizes the likelihood of preserving this neighb...

Mapping grain orientation in crystalline solids is essential to investigate the relationships between local microstructure and crystallography and interpret materials properties. One of the main techniques used to perform these studies is electron backscatter diffraction (EBSD). Due to the limited measurement throughput, however, EBSD is not suitab...

Markush structures are molecular skeletons containing not only specific atoms but also placeholders to represent broad sets of chemical (sub)structures. As genus claims, they allow a vast number of compounds to be claimed in a patent application without having to specify every single chemical entity. While Markush structures raise important questio...

Smart MicroGrids (SMGs) can be seen as a promising option when it comes to addressing the urgent need for sustainable transition in electric systems from the current fossil fuel-based centralised system to a low-carbon, renewable-based decentralised system. Unlike previous studies that were restricted to a limited number of actors and only took a m...

This paper discusses the existence of a solution for the system of integro-differential equations. By using a certain measure of noncompactness through the generalized Darbo fixed point theorem, we deduce conditions that guarantee the existence of a solution for the system. The advantage of the Darbo fixed point theorem is it helps us to impose wea...

∂ t β u + ( − Δ ) s u + ( − Δ ) 1 + s u + ( − Δ ) 1 + s ∂ t β u = − ( − Δ ) s f ( u ) ,
with the Caputo time fractional derivatives and the spectral fractional Laplacian operators. To the best of our knowledge, there are few result...

Understanding the spatial variation of soil properties is central to many sub-disciplines of soil science. Commonly in soil mapping studies, a soil map is constructed through prediction by a statistical or non-statistical model calibrated with measured values of the soil property and environmental covariates of which maps are available. In recent y...

We present higher order necessary conditions for a model of welfare economics, where the preference mapping has a star-shape property. We assume that the preferences can be satiable and can be described by an arbitrary preference set, without the use of utility functions. These conditions are formulated in terms of higher-order directional derivati...

In this work, a new basic framework of robotic mechanism topology is proposed, which includes: ① two important concepts (i.e., topological structure and kinematic characteristics), ② three basic formulas (i.e., POC equation of serial mechanisms, POC equation of parallel mechanisms (PMs), and DOF formula) and ③ topological structure synthesis method...

Tone mapping reproduces the true radiance map of a scene from a high dynamic range (HDR) image while preserving sharp edges. Popular approaches extract base and texture layers from an HDR image, adjust and combine them to obtain the final results. Due to the drawbacks of the priors used in layer decomposition, these methods suffer from over-enhance...

In this paper, we solve the Cauchy problem for a hyperbolic system of first-order PDEs defined on a certain Banach space X. The system has a special semilinear structure because, on the one hand, the evolution law can be expressed as the sum of a linear unbounded operator and a nonlinear Lipschitz function but, on the other hand, the nonlinear pert...

The irregularity strength of a simple graph , denoted is a certain measure of the level of irregularity of a graph. It indicates how hard it is to make an irregular multigraph of G via multiplication of its selected edges. It is however more commonly set forth through k‐weightings, that is, mappings , assigning every vertex the weighted degree . In...

This special issue invites authors to focus on and investigate the managerial implications of intangible assets and IC in action inside different types of organizations.
