Restoring original signals from pile-up using deep learning
No full textPile-up signals are frequently produced in experimental physics. They create inaccurate physics data with high uncertainties and cause multiple problems. Therefore, the correction of pile-up signals is crucially required. In this study, we implemented a deep learning method to restore the original signals from signals piled up with unwanted signals. We showed that a deep learning model could accurately reconstruct the original signal waveforms from the pile-up waveforms. By substituting the pile-up signals with the original signals predicted by the model, the energy and timing resolution of the data are notably enhanced. The model implementation significantly improved the quality of the particle identification plot and particle tracks. This method is applicable to similar problems, such as separating multiple signals or correcting pile-up signals with other types of noises and backgrounds. © 2023 Elsevier B.V.11Nsciescopu
Noise signal identification in time projection chamber data using deep learning model
No full textDeep learning has been employed in various scientific fields and has provided promising results. In this study, a deep learning classifier was implemented to improve the quality of data obtained from a time projection chamber. Digital waveforms of the detected signals were classified into the following three categories: particles, noises, and particles piled up with noises. A simple 1-dimensional convolutional neural network was developed for the classification. The model demonstrated an excellent performance on the test dataset. Its practical performance was also examined using track images and particle identification plots by comparing the original and clean data without the noise signals. The comparison clearly showed that the deep learning model improved the quality of data. The current study presents an effective application of the deep learning model for the time projection chamber data. © 2023 Elsevier B.V.11Nsciescopu

Abstract
Taking into account that the uterine pump disruption is one of the leading pathogenic links of infertility in external endometriosis, a significant role of this factor can be detected and in adenomyosis. Diagnosis of uterine peristalsis held with ultrasonography (US), and the study of intrauterine transport was made by hysterosalpingoscintigraphy. Disperistaltic waves at were revealed predominantly in periovulatory phase with the average rate of 4.8 ± 0.23 waves / min. In the control group only single disperistaltic waves throughout the cycle, and their frequency did not exceed 0.4 ± 0.11 waves / min. In all the women with the lack of intrauterine transport either disperistaltic or complete absence of subendometrial layers of myometrium contractions wave were found. The significant increase of hysterosalpingoscintigraphy negative results and contralateral transport depending on the patients’ age was revealed (p <0.01 and p <0.05, respectively). Therefore, patients with adenomyosis and impaired uterine peristaltic older than 30 years old should be recommended one of the techniques of extracorporal fertilization with embryo transfer technology, except for intrauterine insemination.
Key words: adenomyosis, infertility, uterine pump, uterine peristalsis.
Реферат
Учитывая, что нарушение работы маточной помпы - одно из ведущих звеньев патогенеза бесплодия при наружном эндометриозе, может быть обнаружена значимая роль этого фактора и при аденомиозе. Диагностика маточной перистальтики проводится при ультрасонографии (УЗИ), а исследование внутриматочного транспорта – методом гистеросальпингосцинтиграфии (ГССГ). Дисперистальтические волны при аденомиозе обнаружены преимущественно в периовуляторной фазе со средней частотой 4,8±0,23 волн/мин. В контрольной группе наблюдались только единичные дисперистальтические волны на протяжении всего цикла и их частота не превышала 0,4±0,11 волн/мин. У всех женщин с отсутствием внутриматочного транспорта обнаружены дисперистальтика или полное отсутствие волн сокращения субэндометриальных слоев миометрия. В ходе исследований обнаружено, достоверное увеличение числа случаев отрицательных результатов ГССГ и контралатерального транспорта с возрастом пациенток (р<0,01 и p<0,05, соответственно). Поэтому пациенткам с аденомиозом и нарушением маточной перистальтики старше 30 лет следует рекомендовать одну из методик экстракорпорального оплодотворения с технологией переноса эмбриона, исключая внутриматочную инсеминацию.
Ключевые слова: аденомиоз, бесплодие, маточная помпа, маточная перистальтика

No full textThe future of the aerospace industry is directly related to the development and modernization of the heat-loaded components of hypersonic aircraft: jet engines, nose tips and sharp leading edges of the wings, which are required to withstand ultrahigh temperatures (above 2000°C) caused by aerodynamic heating. The greatest practical interest for the aerospace industry is centered around ultra-high temperature ceramics based on borides, nitrides, carbides, carbonitrides and double transition metal carbides [1–4]. These materials have unique physical and chemical properties. They are characterized by unparalleled combination of heat resistance, thermal conductivity, refractoriness (melting points above 3000°C), hardness, as well as electrical and thermal properties close to those of metals [5–9]. According to recent publications, hafnium carbonitride of optimum composition not only has good mechanical properties and high thermal conductivity, but also is believed to have the highest melting point (above 4200°C) among all currently existing systems. This peak refractoriness is explained by several factors affecting the melting point: the presenc
Study of the A+13C interaction at heavy ION acceleration DC-60
No full textIn astrophysics, nuclear reactions play a great role in understanding the formation of our universe.The reaction 13C(α,n)16O is considered to be the main source of neutrons for the s process at low temperatures in low mass stars in the asymptotic giant branch. Many problems exist in analyzing this reaction using conventional experimental methods; therefore, we aimed to obtain and analyze data from the a +13C resonance elastic scattering reaction at small angles and low energies using Thick Target Inverse Kinematic method (TTIK) at heavy ion accelerator DC-60
The Yukos Case: The New Dimension in Money Laundering Cases
No full textPhD - Vol. 1 of 2 only - Vol. 2 contains appendices, tables of cases and legislation, and bibliography.The Yukos case is known for its unprecedented character and complexity as a
Russian corporate, tax and money laundering case. It continues to raise political and legal
problems, both domestically and internationally, and has already become a symbol of the
contemporary Russian political regime. This dissertation analyses in detail the criminal and
corporate aspects of the case, and focuses mainly on the reasons for, and the development
and implications of the embezzlement and money laundering case, which is known as the
backbone of the Yukos Affair.
The thesis is primarily based on a comparative analysis of the international
academic findings, case law and the Russian data on the case. The dissertation also
discusses in detail the political nature of the Yukos Affair, whilst attempting to show the
substantive aspects of case.
The findings of the dissertation highlight new types of risk that result from the
politically motivated application of Russian anti money laundering legislation to the
activities of the international corporate groups, which has been enacted on the basis of the
internationally recognised principles.
The paper also describes the nexus between the corporate tax evasion schemes,
which have been widely used in Russia, and money laundering risks for corporations. Such
a situation creates potentially unavoidable criminal risks for all corporate groups that have
functioned in Russia over the recent decade. The thesis shows that the corporations, which
invest directly and indirectly in the Russian economy, must be aware of the politically
driven corporate criminal risks, which quite commonly are not reflected in the corporate
disclosure data, and remain unnoticed by the investors.
The paper is unique as reflects the personal experiences of the author as the longterm
leading lawyer to the Yukos group and as the consultant on the Yukos-related cases
