Formulation of perfect‐crystal diffraction from Takagi–Taupin equations: numerical implementation in the crystalpy library

Journal of Synchrotron Radiation, Volume 31, Issue 6, Page 1469-1480, November 2024.
The Takagi–Taupin equations are solved in their simplest form (zero deformation) and equations of the diffracted and transmitted amplitudes are obtained using a matrix model. The theory presented is coded in the open‐source software package crystalpy.The Takagi–Taupin equations are solved in their simplest form (zero deformation) to obtain the Bragg ...

New opportunities for time‐resolved imaging using diffraction‐limited storage rings

Journal of Synchrotron Radiation, Volume 31, Issue 5, Page 1299-1307, September 2024.
The opportunities for time‐resolved X‐ray imaging at diffraction‐limited storage rings are demonstrated by benchmarking time‐resolved 2D and 3D imaging at ForMAX, MAX IV. The enhanced flux density provided by the MAX IV storage ring allows micrometer‐resolution time‐resolved imaging at 2 kHz and 1.1 MHz acquisition rates in 3D and 2D, respectively.The ...

On central series of some Chernikov p-groups

Науковий вісник Ужгородського університету. Серія «Математика і інформатика», 2020
В цій роботі досліджується структура центрального ряду черніковської \(p\)-групи \(G\), яка містить максимальну повну абелеву підгрупу \(M\) індексу \(p\). Добре відомо, що така група є гіперцентальною групою. З іншого боку із теорії розширень груп також добре відомо, що будову цієї групи можна визначити за допомогою певного цілочислового $p$-адичного ...

Estrogen‐dependent gene regulation: Molecular basis of TIMP‐1 as a sex‐specific biomarker for acute lung injury

Physiological Reports, Volume 12, Issue 17, September 2024.
Abstract Increased circulating tissue inhibitor of metalloproteinases‐1 (TIMP‐1) levels have been observed in patients with acute lung injury (ALI). However, the sex‐specific regulation of TIMP‐1 and the underlying molecular mechanisms have not been well elucidated. In this study, we found that plasma TIMP‐1 levels were significantly higher in COVID‐19

Some topological properties of residually Černikov groups [PDF]

Glasgow Mathematical Journal, 1982
In this paper we shall indicate how to generalise the concept of a cofinite group (see [7]). We recall that any residually finite group can be made into a topological group by taking as a basis of neighbourhoods of the identity precisely the normal subgroups of finite index.
