Micro‐motion parameter extraction of rotating target based on vortex electromagnetic wave radar
Authors: Yuan Hang , Luo Ying , Chen Yi‐Jun , Liang Jia , Liu Ying‐Xi
Published: June 2021

The vortex electromagnetic (EM) wave radar has the potential to obtain more accurate micro‐motion parameters for target recognition. However, with the existing algorithms of micro‐motion parameter extraction it is difficult to obtain the real rotation radius and tilt angle of a rotational target in the presence of multiple scattering points in the radar beam. A micro‐motion parameter extraction algorithm for rotating targets based on the vortex EM wave radar is proposed in this article. The angular Doppler is obtained from the dual‐mode vortex EM echoes. The time interval between the maximum and minimum angular Doppler frequency is derived. The relationship between the time interval and micro‐motion parameters is shown. By combining the linear Doppler and the angular Doppler, the micro‐motion parameters are roughly estimated. Then, fine micro‐motion parameters are obtained by using an iterative soft threshold algorithm. The proposed algorithm can extract the real rotation radius and tilt angle in the case of multiple scattering points. The performance and robustness of the algorithm are proved by simulations.

Luminous red novae (LRNe) are astrophysical transients associated with the partial ejection of a binary system’s common envelope shortly before its merger. Here we present the results of our photometric and spectroscopic follow-up campaign of AT 2018bwo (DLT 18x), a LRN discovered in NGC 45, and investigate its progenitor system using binary stellar-evolution models. The transient reached a peak magnitude of Mr = −10.97 ± 0.11 and maintained this brightness during its optical plateau of tp = 41 ± 5 days. During this phase, it showed a rather stable photospheric temperature of ∼3300 K and a luminosity of ∼1040 erg s−1. Although the luminosity and duration of AT 2018bwo is comparable to the LRNe V838 Mon and M31-2015LRN, its photosphere at early times appears larger and cooler, likely due to an extended mass-loss episode before the merger. Toward the end of the plateau, optical spectra showed a reddened continuum with strong molecular absorption bands. The IR spectrum at +103 days after discovery was comparable to that of a M8.5 II type star, analogous to an extended AGB star. The reprocessed emission by the cooling dust was also detected in the mid-infrared bands ∼1.5 years after the outburst. Archival Spitzer and Hubble Space Telescope data taken 10−14 yrs before the transient event suggest a progenitor star with Tprog ∼ 6500 K, Rprog ∼ 100 R⊙, and Lprog = 2 × 104 L⊙, and an upper limit for optically thin warm (1000 K) dust mass of Md < 10−6 M⊙. Using stellar binary-evolution models, we determined the properties of binary systems consistent with the progenitor parameter space. For AT 2018bwo, we infer a primary mass of 12–16 M⊙, which is 9–45% larger than the ∼11 M⊙ obtained using single-star evolution models. The system, consistent with a yellow-supergiant primary, was likely in a stable mass-transfer regime with −2.4 ≤ log(Ṁ/M⊙ yr−1) ≤ −1.2 a decade before the main instability occurred. During the dynamical merger, the system would have ejected 0.15–0.5 M⊙ with a velocity of ∼500 km s−1.

Authors: Andrzejewski Maciej , Daszkiewicz Paweł , Urbański Patryk , Rymaniak Łukasz , Woch Aleksandra
Published: June 2021

Vehicles used in rail transport are characterized by a long service life, which is caused, among others, by the high cost of their purchase. In Poland, the average age of freight diesel locomotives exceeds 40 years. Increasing the wear and tear of vehicles has an impact on many aspects of machine operation, including environmental pollution. Significant wear and degradation of the powertrain components contributes to the increase in pollutant emissions and fuel consumption, which is closely correlated with the production of carbon dioxide. Modernizations involving the replacement of the drive unit are performed in order to reduce the negative impact of rail vehicles on the environment. The article compares the energy consumption of the ST44 locomotive prior to and after modernization. The older 14D40 two-stroke internal combustion engines were replaced with a more modern engine unit 12CzN26/26. Fuel consumption tests were carried out on a test bench using a OW6300 water resistor.

Detection of slag inclusions using infrared thermal imagining system
Authors: Jamrozik Wojciech , Górka Jacek
Published: June 2021

Assuring high quality of welded joins is a vital task in many industrial branches also when joints are made manually. It is the case metal-arc welding with covered electrode. One of main imperfection, that can occur in this process is slag inclusion. In the paper an method for detection of slag inclusion in multipass manual welding is proposed and validated. The key idea of the method is that small temperature disturbances will be noticeable in consecutive cross-section of joint in the cooling pass. Temperature distribution weld face was measured with longwave infrared camera (LWIR). For consecutive cross-section made in IR representation of joint differences in mean temperature was calculated to assess the cooling rate directly after the elements were welded. It can be made because on each thermogram the whole joint is visible, thus position of electrode in time can be easily marked. Results of slag inclusion detection were compared with radiographic images of made joints. In the future additional studies will be performed in order to generalize proposed method to wider group of materials and for more complex welds.

The social transformations taking place in Russia influenced by socio-economic changes have led to a revision of many socio-pedagogical guidelines. Today the school as a leading social institution cannot solve educational problems effectively without interaction with various children's and youth public associations, which play an important role in the socialization of the younger generation, meeting its needs, self-realization and self-development. Young people feel a especial need for the activities of such associations because of their age characteristics young people are looking for recognition of their personality, dignity and respect for themselves. However, the modern youth movement in Russia is represented not only by organized structures, but also by an informal youth initiative. The importance of informal associations for the socialization of the younger generation is acquiring special attention today. Practice shows that the process of socialization of the younger generation is carried out mainly spontaneously, without proper coordination of the educational influences of various socio-pedagogical systems.

Authors: Speranskaya A.V. , Prokopyeva S.A. , Popovich M.M.
Published: June 2021

The features of the teachers’ burnout syndrome that depends on their place of work are compared. The organizational factor is considered to be the reason that contributes to the formation of this phenomenon. It is stated that secondary education teachers are more susceptible to the development of emotional burnout in comparison with higher education teachers who have the same work experience. Secondary education teachers are characterized by the formation of a phase of resistance which is clearly revealed through an inadequate emotional response to problems that arise in their professional activity. In hard situations they prefer to address to a psychologist’s for help to solve their problems and do not address to the colleagues and management for the fear of showing their incompetence. In contrast, the higher education teachers seek help from colleagues, management and the Internet, so, they do not have feelings of helplessness. It is necessary to provide psychological support to the teachers taking into account organizational factors.

Published: June 2021

Hintergrund Auf dem Weg zu einer wertebasierten und patientenzentrierten medizinischen Versorgung rückt das subjektiv vom Patienten empfundene Ergebnis einer Behandlung zunehmend in den Fokus. Als Messinstrument dienen dabei Patient-reported Outcome Measures (PROMs). Bei chronisch entzündlichen Darmerkrankungen hat sich der englischsprachig validierte Fragebogen IBD-Control zur Messung des Behandlungserfolgs aus Patientensicht etabliert. Da dieser bisher nicht auf Deutsch vorliegt, machte sein Einsatz in der deutschsprachigen Schweiz im Vorfeld eine Übersetzung sowie Validierung notwendig.

Methoden Die englischsprachige Originalversion des IBD-Control-Fragebogens wurde mittels „forward-backward translation“ ins Deutsche übertragen und anschließend an 154 Patienten mit Morbus Crohn oder Colitis ulcerosa validiert.

Resultat Die Übersetzung des IBD-Control erfolgte durch eine multidisziplinäre Expertengruppe sowie Fachübersetzer. Der IBD-Control-D zeigte eine große Akzeptanz. Eine starke Korrelation zwischen dem IBD-Control-8-Subscore mit der visuellen Analogskala des IBD-Control-D (r=0,632) zeigt die Validität des Instruments. Die Konstruktvalidität zeigt sich in der starken Korrelation zwischen der Krankheitsaktivität der letzten 6 Monate und dem IBD-Control-8-Subscore (r=0,640) sowie dem IBD-Control-VAS-Score (r=0,622) sowie zwischen dem IBD-Control-8-Subscore und dem Harvey Bradshaw Index (r=–0,620) und dem partiellen Mayo Score (r=–0,679) wie auch zwischen dem IBD-Control-VAS-Score und dem Harvey Bradshaw Index (r=–0,484) sowie dem Mayo Score (r=–0,435). Die interne Konsistenz ist gegeben (Cronbachs α = 0,840).

Schlussfolgerung Mit der hier vorgestellten deutschen Version des IBD-Control, dem IBD-Control-D, liegt nun auch im deutschsprachigen Raum ein valides, benutzerfreundliches und geeignetes Instrument vor, um das subjektive Krankheitsempfinden und das Behandlungsoutcome im Kontext chronisch entzündlicher Darmerkrankungen zu erfassen.
Osteoporose bei Diabetes mellitus
Authors: Tsourdi Elena , Hofbauer Lorenz C.
Published: June 2021

Aufgrund ihrer hohen und mit zunehmendem Alter steigenden Prävalenz in der Allgemeinbevölkerung sind Osteoporose und Diabetes mellitus globale Gesundheitsprobleme. Osteoporose kann sowohl mit antiresorptiven, als auch osteoanabolen Medikamenten erfolgreich behandelt werden. Während diese Medikamente bei Patientinnen mit postmenopausaler und Patienten mit männlicher Osteo porose eindeutig das Frakturrisiko senken, ist noch unklar, ob sie bei Menschen mit diabetischer Knochenerkrankung die gleiche Wirksamkeit haben. Darüber hinaus sind aus dem Knochen stammende Zytokine (Osteokine) in der Lage, den Glukosestoffwechsel zu beeinflussen. Es ist denkbar, dass Medikamente gegen Osteoporose durch ihre Modulation des Knochen umsatzes und insbesondere der Osteokine den Blutzuckermetabolismus beeinflussen können. Die Modulation des Knochenumsatzes durch Osteoporosemedikamente scheint für den Glukosestoff- wechsel des Menschen jedoch keine klinisch bedeutsame Rolle zu spielen. Substanzen aus der Gruppe der Bisphosphonate sind Medikamente der 1. Wahl für die Behandlung der Osteoporose bei diabetischen Patient/-innen, während Denosumab für ältere Pa tient/-innen, insbesondere bei eingeschränkter Nierenfunktion, geeignet ist. Osteoanabole Substanzen wiederum kommen vorrangig bei Menschen mit schweren Formen von Osteoporose zum Einsatz.
