Limiting Distributions for the Minimum-Maximum Models

Mathematics, 2019
We consider the extreme value problem of the minimum-maximum models for the independent and identically distributed random sequence and stationary random sequence, respectively.

A New Kind of Parallel Natural Difference Method for Multi-Term Time Fractional Diffusion Model

Mathematics, 2020
Multi-term time fractional diffusion model is not only an important physical subject, but also a practical problem commonly involved in engineering. In this paper, we apply the alternating segment technique to combine the classical explicit and implicit ...

Analysis of Reentry and Break-Up Forces from Impulse Facility Experiments and Numerical Rebuilding

, 2022
This paper shows new findings for the break-up of large spacecraft during reentry into Earth’s atmosphere. The break-up scenario at high altitude drives the ground impact area for parts surviving the reentry.

Numerical investigation of transitional supersonic axisymmetric wakes

, 2006
Transitional supersonic axisymmetric wakes are investigated by conducting various numerical experiments. The main objective is to identify hydrodynamic instability mechanisms in the flow at M=2.46 for several Reynolds numbers, and relating these to ...

Mathematical modeling of Elbrus glaciers in the 21st century. Part 2. Forecasting glacier evolution and lake formation under various SSP scenarios

Лëд и снег
Probable scenarios of future changes in the Elbrus glaciers and associated with them phenomena such as formation of glacial lakes and remaining ice masses buried under the debris cover are considered. The SSP scenarios (SSP1–1.9, SSP1–2.6, SSP2–4.5, SSP3–

Global glaciological models: a new stage in the development of methods for predicting glacier evolution. Part 1. General approach and model architecture

Лëд и снег, 2021
For several decades, mathematical models of mountain glaciers and ice sheets have been used to study the dynamics of the cryosphere. In recent years, a new step in glaciological modeling has made possible to recon- struct processes in mountain-glacial ...

Global glaciological models: a new stage in the development of methods for predicting glacier evolution. Part 2. Formulation of experiments and practical applications

Лëд и снег, 2022
Global glacier models provide a new way for studying glaciers on the regional and global scales. They make it possible to perform predictive experiments - for example, to forecast changes in glaciation and river runoff, and diagnostic ones – to identify ...

Effects of the Fluid Replacement Method During Online Hemodiafiltration on the Solute Removal Performance and Biocompatibility Using the Asymmetric Cellulose Triacetate Membrane

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.
