Experimental and constitutive modeling investigations on marble in Jinping Underground Laboratory

Deep Underground Science and Engineering, EarlyView.
The objective of this study is to reveal the underlying mechanisms behind the brittle‐ductile transition of the marble through a combination of experimental research and constitutive modeling. A series of triaxial compression and triaxial cyclic loading tests are conducted.

A novel construction approach for the pore structure model principally focuses on the controllable roundness of rock particles

Deep Underground Science and Engineering, EarlyView.
Particle rounding effects comparison of different methods: (a), (b), and (c) are the rounding results using the B‐spline curve method with different R; (d), (e), and (f) are the results of vertex rounding substitution method with different rounding radii.

Peak Integration of Electropherograms in GMP and Research Labs: Navigating Increased Scrutiny Amid Data Integrity Audits and Inspections

ELECTROPHORESIS, EarlyView.
ABSTRACT Capillary electrophoresis (CE) often offers superior separation relative to chromatography for macromolecules like monoclonal antibodies (mAbs), a major pharmaceutical class. However, electropherogram baselines pose challenges that traditional chromatography algorithms cannot address, requiring complex integration processes.

Comparing Different Light Models for Virtual Electrodes in Optoelectronic Tweezers

ELECTROPHORESIS, EarlyView.
ABSTRACT Optoelectronic tweezers (OET) allow for the physical manipulation of particles of interest via dielectrophoresis (DEP) in microfluidic devices. To produce the nonuniform electric field required to enable DEP, light is used to expose a photoconductive film and create a so‐called virtual electrode (VE).

Non‐Hydrostatic Model for Simulating Moving Bottom‐Generated Waves: A Shallow Water Extension With Quadratic Vertical Pressure Profile

International Journal for Numerical Methods in Fluids, EarlyView.
In this article, we derive a non‐hydrostatic extension to the SWE to solve bottom‐generated waves along with its pressure relation. This relation is built on a linear vertical velocity assumption, leading us to a quadratic pressure profile, where we alternatively write it so that we can solve it by a projection method without ambiguity due to the ...

Description and Convergence Order Analysis of the Finite Element‐Volume Spatial Discretization Method

International Journal for Numerical Methods in Fluids, EarlyView.
This article presents the principles of Finite Element‐Volume discretization and conducts an analysis of its properties and convergence orders. The discretization ensures local mass conservation, second‐order convergence for velocity, and first‐order convergence for pressure.

Multiple Seasonal Autoregressive Integrated Moving Average Models

Journal of Forecasting, EarlyView.
ABSTRACT Many empirical time series show periodic patterns. SARIMA models and exponential smoothing methods are classical approaches to account for seasonal dynamics. However, they allow to model just one periodic component, while several time series have multiple seasonality, with periodic components possibly tangled among them.

Long-Scale Ollivier Ricci Curvature of Graphs

Analysis and Geometry in Metric Spaces, 2019
We study the long-scale Ollivier Ricci curvature of graphs as a function of the chosen idleness. Similarly to the previous work on the short-scale case, we show that this idleness function is concave and piecewise linear with at most 3 linear parts.
