Interaction of protons with nuclei in the Born approximation (II) [PDF]

Ядерна фізика та енергетика
In the framework of the Born approximation, comparison of the previously used approaches, in which analytical expressions for the scattering amplitudes of particles by nuclei were obtained using the expansion of the potential into the series up to the ...

On the Expediency and Possibilities of Approximating a Pure Delay Link

Информатика и автоматизация, 2022
When solving problems of controlling an object with delay, it is often necessary to approximate a pure delay link with a minimum phase link in order to ensure the possibility of using analytical methods for regulator design.

Approximation orders of formal Laurent series by β-expansions

Finite Fields and Their Applications, 2008
Let \(\mathbb F\) be a finite field of \(q\) elements. Let \(\mathbb F((X^{-1}))\) be the field of formal Laurent series \[ \left\{\sum_{n=n_0}^\infty a_n X^{-n}\mid a_n\in\mathbb F, n_0\in\mathbb Z\right\}. \] Let \(\beta\in\mathbb F((X^{-1}))\) with \(\|\beta\|>1\). The \(\beta\)-expansion of \(x\in\mathbb F((X^{-1}))\), \(\|x\|

Propagation conditions of an eccentric crack in a semi-circular disk loaded in I+II mixed mode [PDF]

MATEC Web of Conferences, 2020
Multi-parameter fracture mechanics concept is applied to investigate crack propagation conditions during a three-point bending (3PB) test performed on an asymmetrical semi-circular disk under I+II mixedmode loading.

Host movement, transmission hot spots, and vector-borne disease dynamics on spatial networks

Infectious Disease Modelling, 2022
We examine how spatial heterogeneity combines with mobility network structure to influence vector-borne disease dynamics. Specifically, we consider a Ross-Macdonald-type disease model on n spatial locations that are coupled by host movement on a strongly

Therapeutic Apheresis in Nigeria: A Multi‐Center Summary of Abstracts From the Inaugural Nigerian Society for Apheresis Scientific Meeting

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...

Decay analysis of bivariate Chebyshev coefficients for functions with limited regularity

Results in Applied Mathematics
The Chebyshev polynomial approximation is a useful tool to approximate smooth and non-smooth functions. In fact, for a sufficiently smooth function, the partial sum of Chebyshev series expansion provides optimal polynomial approximation.

On good approximations and Bowen-Series expansion

, 2020
We consider the continued fraction expansion of real numbers under the action of a non-uniform lattice in PSL(2,R) and prove metric relations between the convergents and a natural geometric notion of good approximations.

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...
