A wellbore creep model based on the fractional viscoelastic constitutive equation
Petroleum Exploration and Development, 2017 To simulate the evolution of wellbore creep accurately, predict and prevent severe accidents such as borehole wall sloughing, casing collapse and sticking of the drill, based on previous studies, the springpot element was introduced into the classical ...

Synthesis of fractional-order elements using the RC-EDP approach
2017 European Conference on Circuit Theory and Design (ECCTD), 2017 Using the theory of analyzing the properties of RC-EDP (resistive-capacitive elements with distributed parameters) structures we propose the synthesis of elements with fractional impedance (EFI)-fractional capacitors Cα (0 < α < 1) suitable for analogue function block design.

Molecular Oncology, EarlyView.Tumour heterogeneity and clonal evolution of metastatic salivary gland cancer were evaluated in two patients with adenoid carcinoma and one patient with myoepithelial carcinoma. Radiology‐guided autopsy enabled multi‐region sampling (total samples n = 149), followed by whole‐genome sequencing and phylogenetic reconstruction (17 tumour samples, 4–7 per ...

A Mixed Finite Element Formulation for the Conservative Fractional Diffusion Equations
Advances in Mathematical Physics, 2016 We consider a boundary-value problem of one-side conservative elliptic equation involving Riemann-Liouville fractional integral. The appearance of the singular term in the solution leads to lower regularity of the solution of the equation, so to the ...

Fractional-order elements of complement order
, 2020 The design of analogue fractional-order systems requires the presence of fractional-order elements (FOEs), capacitive and/or inductive, featuring fractional order α (0 < α < 1). As currently FOEs are not available as discrete elements, suitable RC networks are used to overcome this obstacle.

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
FEBS Open Bio, EarlyView.We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

YIPFα1A expression is regulated by multilayered molecular mechanisms
FEBS Open Bio, EarlyView.YIPFα1A, a five‐pass Golgi protein, is regulated at multiple layers. (1) Rare‐codon enrichment drives translation‐coupled mRNA decay. (2) A proximal 3′‐UTR element stabilizes mRNA. (3) A distal 3′‐UTR element included by alternate poly(A) site usage represses translation, which can be overridden by the proximal 3′‐UTR element.
