Abstract

A brief review of the recent results on the hadronic cross section measurements with the CMD-3 detector at the e+e− collider VEPP-2000 is given. Focus is made on the processes with charged kaons in multihadron events, which have a strong impact on strange meson spectroscopy and form factors that are important ingredients in the Dalitz plot analysis. Experimental data relevant to the topic are presented from the broad energy range covered by VEPP-2000 and compared to earlier measurements by the different collaborations. The analysis is based on the integrated luminosity of about 100 pb−1 collected in 2011, 2012 and 2017.

60. SNR-Based Inter-Component Phase Estimation Using Bi-Phase Prior Statistics for Single-Channel Speech Enhancement

Author

Barysenka, Siarhei Y. and Vorobiov, Vasili I.

Abstract

The fundamental problem of phase-aware single-channel speech enhancement is the estimation of the harmonic phase of signal components from noisy observations. One approach to obtain an estimate of the harmonic phase is by smoothing the noisy harmonic phase in the time domain. Accurate identification of the smoothing regions is crucial to achieve the best enhancement results. Previous works have introduced a binary hypothesis framework for detecting these regions, which is formulated individually for each harmonic component based on von Mises statistics and local harmonic SNR levels. Later, smoothing frameworks have been proposed in the inter-component phase domain, where the inter-component phases follow the temporal constancy property for clean speech signals. However, these frameworks either do not formulate an SNR-dependent smoothing threshold or impose it empirically. The aim of this work is to formulate an SNR-dependent binary hypothesis framework for smoothing in the inter-component phase domain, using prior inter-component phase statistics. The framework then reconstructs the instantaneous phases of the enhanced speech signal components. This proposed framework results in superior speech intelligibility enhancement, reduces phase deviation, and does not introduce auditory buzziness artifacts compared to the previously developed framework that does not formulate an SNR-dependent smoothing threshold.

Abstract

Since December 2010, the CMD-3 detector has collected data at the electronpositron collider VEPP-2000. The sample of the accumulated data corresponds to about 60 pb−1 of integrated luminosity in the c.m. energy from 0.32 up to 2 GeV. Preliminary results of the analysis of various processes e+e− annihilation to hadrons are presented. It is shown the processes with multihadron events have several intermediate states which must be taken into account to correctly describe the angular and invariant mass distributions as well as cross section dependence versus energy.

Abstract

The process of building of the security and defense sector of Ukraine is accompanied by an integrated approach to strengthening the combat capability of military formations. The forms and methods of combat operations are changing, combat technology is becoming more and more complex, but a person remains the decisive part in performing military-combat tasks. At the same time, the critical importance in neutralizing and mitigating the impact of military threats on Ukraine's national security continues to depend on the high morale and psychological state of military personnel and the psychological readiness of the personnel of the security and defense sector of Ukraine to fulfill the tasks and their resilience to combat stress.For the successful accomplishment of the tasks, the forces of the security and defense sector of Ukraine should have a significant combat capability which includes the following main components: personnel, weapons, equipment, material resources. One of the most important is the servicemen, because only their successful activity ensures the reliable operation and use of weapons and military equipment. For qualitative performance of the set military and combat tasks, servicemen must have a set of necessary professional qualities, which in aggregate constitute a moral and psychological state.An analysis of modern legal and regulatory documents showed that there are different approaches to the content and structure of the concept of "moral and psychological state" of personnel and the difference in its evaluation and formation.The moral and psychological state of a serviceman is the current state of the human person's psyche, which is caused by the influence of the internal (professional qualities and individual psychological features of the person) and external (social, political, material and technical and natural) factors, which reflects his readiness to perform the service -battle tasks in the usual and extreme conditions, the components of which are the military-professional and psychological potentials of the serviceman.In our days, practical approaches to assessing the moral and psychological state as the most important component of the military potential of military formations are based on the use of appropriate methods, which are set out in the legal and regulatory documents of the forces of the security and defense sector of Ukraine., Проведено аналіз нормативно-правових документів, які регламентують порядок морально-психологічного забезпечення професійної діяльності сил сектору безпеки і оборони України. Визначено, що у документах є різні підходи до вибору категоріального апарату морально-психологічного стану особового складу і розбіжності у його оцінюванні, прогнозуванні та формуванні.

68. Influence of Low-Temperature Annealing on the Structure and Chemical Composition of Cu2ZnSnS4 Films Deposed on Flexible Polyimide Substrates.

Abstract

The Cu2ZnSnS4 (CZTS) films are deposited onto flexible polyimide substrates by spraying inks containing nanoparticles with subsequent low-temperature annealing at 200°C for 10–120 min in an argon atmosphere. By the methods of X-ray diffractometry and Raman spectroscopy, it can be shown that the nanoparticles and films contain the kesterite phase with small amounts of inclusions of the CuxS and CuxSnySz phases. Increasing the duration of growth of nanoparticles and time of annealing of the films, we improve the crystalline quality of kesterite, i.e., of their main phase. It is shown that the obtained CZTS films are nanostructured and do not suffer cracking even after 50 events of bending in an area of 10 × 10 μm. By applying the method of energy-dispersive X-ray analysis to determine the chemical composition of the samples, we show that the nanoparticles and CZTS films contain excess amounts of copper and sulfur but are depleted of zinc. By analyzing the optical characteristics of the layers, we conclude that the width of forbidden zone for synthesized materials is Eg = (1.4–1.5) ± 0.2 eV, which coincides with the available data. The obtained CZTS films are promising for applications as absorbing layers of solar cells of the third generation. [ABSTRACT FROM AUTHOR]

Abstract

The process $e^+e^-{\to}K^+K^-��$ has been studied in the center-of-mass energy range from 1.59 to 2.007\,GeV using the data sample of 59.5 pb$^{-1}$, collected with the CMD-3 detector at the VEPP-2000 $e^+e^-$ collider in 2011, 2012 and 2017. The $K^+K^-��$ final state is found to be dominated by the contribution of the $��(1020)��$ intermediate state. The cross section of the process $e^+e^-{\to}��(1020)��$ has been measured with a systematic uncertainty of 5.1$\%$ on the base of 3009 $\pm$ 67 selected events. The obtained cross section has been used to calculate the contribution to the anomalous magnetic moment of the muon: $a_��^{����}(E

The procedure is based on the application of the boosted decision trees classification method, and uses as input variables, among others, the specific energy losses of charged particle in the layers of the liquid Xenon calorimeter. The efficiency of the procedure is demonstrated by an example of the extraction of events of e+e- to K+K- process in the center of mass energy range from 1.8 to 2.0 GeV., CERN Proceedings, Vol 1 (2017): CERN-BINP Workshop for Young Scientists in e+e- Colliders

Abstract

A cross section of the process $e^+e^- \to \pipi\pipi$ has been measured using 6798$\pm$93 signal events from a data sample corresponding to an integrated luminosity of 9.8 pb$^{-1}$ collected with the CMD-3 detector in the center-of-mass energy range 920--1060 MeV. The measured cross section exhibits an interference pattern of the $��(1020)\to\pipi\pipi$ decay with a non-resonant process $e^+e^- \to \pipi\pipi$, from which we obtain the branching fraction of the doubly suppressed decays (by G-parity and OZI rule): $\BR(��\to\pipi\pipi) = (6.5\pm2.7\pm1.6)\times 10^{-6}$., 16 pages, 6 figures

Abstract

The process $e^+e^- \to K^+K^-��^+��^-$ has been studied in the center-of-mass energy range from 1500 to 2000\,MeV using a data sample of 23 pb$^{-1}$ collected with the CMD-3 detector at the VEPP-2000 $e^+e^-$ collider. Using about 24000 selected events, the $e^+e^- \to K^+K^-��^+��^-$ cross section has been measured with a systematic uncertainty decreasing from 11.7\% at 1500-1600\,MeV to 6.1\% above 1800\,MeV. A preliminary study of $K^+K^-��^+��^-$ production dynamics has been performed.

Abstract

The cross section of the process $e^+e^- \to 3(��^+��^-)$ has been measured using 22 pb$^{-1}$ of integrated luminosity collected with the CMD-3 detector at the VEPP-2000 $e^+e^-$ collider in the c.m. energy range 1.5 -- 2.0 GeV. The measured cross section exhibits a sharp drop near the $p\bar p$ threshold. A first study of dynamics of six-pion production has been performed.
