Authors: Wu Xianming , Fu Longxiang , He Shaobo , Wang Huihai 
Published: May 2022

AbstractDiscrete chaotic system has complex dynamics and becomes to be a present hot topic, but its analogue circuit implementation is rarely discussed. In this paper, by simplifying the logistic map, a new Logistic‐like map is proposed. Its cobweb plots, bifurcations, Lyapunov exponents, and dynamic map are investigated theoretically and numerically. The results show that the Logistic‐like map has complex dynamical behaviours. And then Psim simulation model is proposed to verify the feasibility of analogue circuit implementation. Finally, an analogue circuit experiment is performed and its results are consistent with the simulation results. The circuit designed is very simple and has less components, which can further broaden the applications of discrete chaotic map in applications.

Published: May 2022

AbstractThis paper presents a comprehensive evaluation of the HVDC system's impact on distance protection via systematic and realistic experimental tests, along with theoretical analysis of the root causes of the identified compromised protection performance. A methodology for quantifying the impact of Synchronous Compensation (SC) in supporting the distance protection operation is also established. In this work, the performance of two widely used physical distance protection relays have been evaluated using a realistic Hardware'In'the'Loop (HIL) testing environment, where a total of 480 cases have been tested under a wide range of system scenarios. Representative cases with compromised protection performance are selected, where issues of under/over'reach, faulted phase selection and impedance measurement are identified and analysed. Furthermore, a method for quantifying the required SC level to address the under/over'reach issues resulting from HVDC systems is presented. The method establishes the relationship between the angle difference of the two'end fault current infeeds of the protected line and the SC level. Based on this relationship, the required SC capacity to constrain the angle difference within a targeted limit can be estimated, which offers a useful tool for system operators to appropriately size the SC's capacity with additional valuable insights from the distance protection perspective.
X-ray emission of contact binary variables within 1 kpc

Published: May 2022

Aims.The X-ray emission of contact binaries (EW-type) is an important facet of such systems. Thus, X-ray emitting EW-type binaries (EWXs) are ideal laboratories for studying the X-ray radiation saturation mechanisms as well as binary evolution. By assembling the largest sample to date of EWXs with periods of less than 1 day from the All-Sky Automated Survey for Supernovae Variable Stars Database and X-ray catalogs from theXMM-Newtonand ROSAT missions, we aim to conduct a systematic population study of X-ray emission properties of EWXs within 1 kpc.Methods.We carried out correlation analyses for the X-ray luminosity, log LX, and X-ray activity level log(LX/Lbol) versus the orbital period,P, effective temperature,Teff, metallicity [Fe/H], and the surface gravity log gof EWXs. We investigated the relation between X-ray emission and the mass of component stars in the binary systems. We also performed sample simulations to explore the degeneracy between period, mass, and effective temperature for EWXs.Results.We find strongP–log LXandP–log(LX/Lbol) correlations for EWXs withP ≲ 0.44 days and we provide the linear parametrizations for these relations, on the basis of which the orbital period can be treated as a good predictor for log LXand log(LX/Lbol). The aforementioned binary stellar parameters are all correlated with log LX, while onlyTeffexhibits a strong correlation with log(LX/Lbol). Then, EWXs with higher temperature show lower X-ray activity level, which could indicate the thinning of the convective area related to the magnetic dynamo mechanism. The total X-ray luminosity of an EWX is essentially consistent with that of an X-ray saturated main sequence star with the same mass as its primary, which may imply that the primary star dominates the X-ray emission. The monotonically decreasingP–log(LX/Lbol) relation and the short orbital periods indicate that EWXs could all be in the X-ray saturated state, and they may inherit the changing trend of the saturated X-ray luminosities along with the mass shown by single stars. For EWXs, the orbital period, mass, and effective temperature increase in concordance. We demonstrate that the periodP = 0.44 days corresponds to the primary mass of ∼1.1 M⊙, beyond which the saturated X-ray luminosity of single stars will not continue to increase with mass. This explains the break in the positiveP–log LXrelation for EWXs withP >  0.44 days.

Aims.With the ever-increasing survey speed of optical wide-field telescopes and the importance of discovering transients when they are still young, rapid and reliable source localization is paramount. We present AutoSourceID-Light (ASID-L), an innovative framework that uses computer vision techniques that can naturally deal with large amounts of data and rapidly localize sources in optical images.Methods.We show that the ASID-L algorithm based on U-shaped networks and enhanced with a Laplacian of Gaussian filter provides outstanding performance in the localization of sources. A U-Net network discerns the sources in the images from many different artifacts and passes the result to a Laplacian of Gaussian filter that then estimates the exact location.Results.Using ASID-L on the optical images of the MeerLICHT telescope demonstrates the great speed and localization power of the method. We compare the results with SExtractor and show that our method outperforms this more widely used method. ASID-L rapidly detects more sources not only in low- and mid-density fields, but particularly in areas with more than 150 sources per square arcminute. The training set and code used in this paper are publicly available.

Published: May 2022

Context. The X-ray Integral Field Unit (X-IFU) is the high resolution X-ray spectrometer of ESA’s Athena X-ray observatory. It will deliver X-ray data in the 0.2–12 keV band with an unprecedented spectral resolution of 2.5 eV up to 7 keV. During the observation of very bright X-ray sources the X-IFU detectors will receive high photon rates. The count rate capability of the X-IFU will be improved by using the defocusing option, which will enable the observations of extremely bright sources with fluxes up to ≃1 Crab. In the defocused mode, the point spread function (PSF) of the telescope will be spread over a large number of pixels. In this case each pixel receives a small fraction of the overall flux. Due to the energy dependence of the PSF, this mode will generate energy-dependent artefacts increasing with count rate if not analysed properly. To account for the degradation of the energy resolution with pulse separation in a pixel, a grading scheme (of four grades) will be defined to realize the proper energy response to each event. This will create selection effects preventing the use of the nominal auxiliary response file (ARF) for all events.
Aims. We present a new method for the reconstruction of the spectra obtained from observations performed with a PSF that varies as a function of energy. We apply our method to the case of the X-IFU spectra obtained during the defocused observations.
Methods. We used the end-to-end SIXTE simulator to model defocused X-IFU observations. Then we estimated a new ARF for each of the grades by calculating the effective area at the level of each pixel.
Results. Our method allows us to successfully reconstruct the spectra of bright sources when employed in the defocused mode, without any bias. Finally, we address how various sources of uncertainty related to our knowledge of the PSF as a function of energy affect our results.
Blunt Traumatic Innominate Artery Pseudoaneurysm Endografting without Heparin Due to Severe Brain Injury
Authors: Nieber Derek P. , Lewis C. Taylor , Dayal Rajeev , Khariton Konstantin , Lang Samuel J. , Mack Charles A. 
Published: May 2022

AbstractBlunt traumatic innominate artery injuries occur in polytrauma victims who have suffered high-speed motor vehicle collisions. Their associated injuries may preclude the use of heparin and affect surgical management and perioperative neurological risk. The uniqueness of this case is combining the arterial injury repair with a severe progressive neurological injury that prohibited standard perioperative antiplatelet or anticoagulent use.

Abstract
Objective This study aims to describe our technique and early experience with physician-modified endovascular grafts (PMEGs) for aortic arch diseases in zone 2. We used a total endovascular technique based on a single fenestrated endograft to preserve left subclavian artery (LSA) patency.
Methods From December 2019 to August 2020, six consecutive patients with a variety of thoracic aortic diseases were treated with handmade fenestrated thoracic aortic grafts: four aortic dissections, one penetrating aortic ulcer, and one intramural hematoma. The planning, endograft modification, surgical technique, and follow-up of the patients were described. We evaluated immediate technical success and after 30 days, the LSA patency, Type-1 endoleak, and postoperative complications.
Results Thoracic endovascular aortic repair (TEVAR) was performed for zone 2 in all cases. Immediate technical success, defined as successful alignment of the LSA with a covered stent and no Type-1 endoleak, was achieved in all cases. Patients had a 30-day follow-up computed tomography, which demonstrated LSA patency and no Type-I endoleaks. To date, no strokes, left arm ischemia, paraplegia, or conversions to open surgery have been reported; one patient operated for acute Type B dissection died during the early follow-up.
Conclusion TEVAR for zone 2 with a PMEG to maintain LSA patency achieved technical success and early durability. It is expected that with longer follow-up and a larger number of cases, these results will be confirmed.
A Misdiagnosed Case of Endoleak Type-III Caused by Inadvertent Bilateral Limb Insertion in the Same Limb Gate of the Ovation Endograft

Published: May 2022

AbstractWe describe an infrequent case of endoleak Type-III due to an unrecognized, inadvertent bilateral limb deployment into the same limb gate of the Ovation aortic endograft, accompanied by thrombosis and acute ischemia. The following computed tomography angiography revealed the open limb gate with the characteristic of radio-opaque polymer in the sealing rings. Intraoperative angiographies via the brachial route identified the open limb gate and facilitated the successful use of an occluding plug to manage the Type-III endoleak.

Published: May 2022

AbstractTransjugular intrahepatic portosystemic shunt (TIPS) is a nonsurgical intervention to reduce portal pressure by creating a low-resistance channel between the portal and systemic circulations. It is a well-accepted treatment for gastroesophageal varices and refractory ascites. This review aims to discuss the evidence-based applications of TIPS in other complications of portal hypertension beyond gastroesophageal varices and refractory ascites.
Sustainable investing in the US and European insurance industry: a text mining analysis
Authors: Gatzert Nadine , Reichel Philipp 
Published: May 2022

AbstractThis paper uses a text mining analysis to study the development of sustainable investing in the European and US insurance industry as reflected in their public reports from 2013 to 2018. The sample comprises 1215 annual, sustainability- and investment-related documents of 77 firms. We develop a dictionary with principles, criteria and terminologies as well as strategies, and differentiate between the quality of reports. Our results show that the number of firms referring to as well as the word count related to sustainable investing substantially increase over the sample period, and that insurers reporting about sustainable investing are on average significantly larger. We also find that European insurers report much more extensively on their sustainable investment practices as compared to US insurers in our sample. Most relevant in 2018 are references to general ESG criteria, followed by responsible investment and the Sustainable Development Goals. Top strategies mentioned were ESG integration and impact investing, whereby we observe that insurers evolve from mentioning one single towards multiple strategies over time. Finally, a regression analysis does not show a value-effect of sustainable investment-related keywords in reporting on Tobin’s Q, which may be due to the rather long-term investment perspective.
Meaning construal and meaning conventionalization of Chinese [X+body part] metonymic compounds from the perspective of cognitive pragmatics
Authors: Li Qi 
Published: May 2022

AbstractIt is common for “body part” nouns to refer to other concepts through metonymy operations in a specific context to produce new meanings in many languages. Some compound words formed by body part nouns as morphemes can also refer to other concepts through metonymy operations, and the degree of conventionalization varies. This study firstly defines the degrees of conventionalization of the target compound words–Chinese [X+body part] metonymic compounds, and divides them into three types: conventionalized, half-conventionalized, and inconventionalized. Then, from the perspective of cognitive pragmatics, this study uses an integrated analysis model of cognitive linguistics and Relevance Theory to analyze the meaning inferential process of metonymic compounds with different degrees of conventionalization. This study has found similarities and differences among them. The similarity is that both speakers and hearers need to achieve “optimal relevance” in the process and the difference is that the lower degree of conventionalization of the compound, the more complicated the meaning inferential process is. Lastly, on the basis of the inferential process, this study summarizes four factors that affect the conventionalization of metonymic compounds: time of word formation, salience of metonymy, clarity of word-forming motivation and contextual support, among which contextual support is the most crucial factor.
Italian items in domestic spaces
Authors: Chianese Francesco 
Published: May 2022

AbstractIn their migration, people carry objects with them, and relocate them through physical spaces and across cultural boundaries. Handed down through generations, these objects become signs of ethnicity beyond their appearance and purpose. Examining the variety of the literary representations of objects and their subsequent translation contributes to the analysis of how material culture migrates within distant cultural systems and from one language to another. This essay focuses on domestic objects depicted by two Italian authors writing about the experience of a migrant coming-of-age in the United States: Helen Barolini and Chiara Barzini. Using diverse multilingual and (self-)translation strategies, they highlight through cultural translation the difficulties of bridging their Italian and American selfhood within an Italian household relocated abroad. In doing so, their relationship with objects underlines how their diasporic experience is entangled with their achievement of self-confidence and independence as women within the context of the Italian diaspora.

Abstract
The article proposes a method of complex comparison of equipment for electrolyte-plasma polishing of surfaces. The Harrington function is used to evaluate the equipment. The values of the function are limited by the numerical interval 0.2 - 0.8. The parameters of the equipment are selected as the evaluation parameters: maximum polishing area per cycle, productivity, power, area occupied by the installation, cost. As a result of a comprehensive assessment, the best type of equipment for electrolyte-plasma polishing, which provides a resource-saving and energy-saving mode of operation was selected. A computer program has been developed with the help of which a generalized evaluation parameter has been calculated and a comparative analysis of the equipment has been performed.

Abstract
The paper investigates the dependence of the surface roughness of aluminum nitride films on the modes of magnetron deposition. The paper shows the difference between the surfaces of polycrystalline aluminum nitride films on ceramized glass and silicon substrates grown under the same conditions. Atomic force microscopy was used to compare the surface roughness parameters of aluminum nitride obtained at different substrate temperatures and the power dissipation in the target. The optimal conditions for forming aluminum nitride films through magnetron sputtering have been determined.

Published: May 2022

Abstract
In the modern world, polymers are used in almost all areas. Modification of polymer surfaces is an urgent task. Increasing adhesion and wettability is one of the important parameters. There are many different methods for increasing adhesion and wettability. The electrolytic plasma method is one of them. After processing the surface of the polymer by this method, the wettability of the surface of modified polymers with water was studied by measuring the size of a drop of technical water on the surface of the polymer. As a result of experimental studies, the modification of polyethylene terephthalate decreased the wetting angle by 11-24%.

Published: May 2022

Abstract
The paper describes a technique for the synthesis of microdiamonds, germanium nanoballs and nanotubes in an argon-germanium arc. The evaporation of germanium atoms was carried out from the surface of a graphite rod, which served as the anode of the arc discharge. The synthesis of microdiamonds was observed on graphite substrates near the anode; germanium nanotubes and germanium nanoballs were also found nearby. It has been established that germanium promotes the synthesis of nano and microdiamonds. Synthesized diamonds have a classic structure with rectangle faces and four hexagons adjacent to the edges of this rectangle. The sizes of microdiamonds reach tens of microns. The diameters of germanium nanotubes are of the order of 50-100 nm, and the length is of the order of 10 μm.
On the question of the applicability of the principle of thermodynamic similarity in liquid alkali metals
Authors: Tsygankov A A 
Published: May 2022

Abstract
In this paper, we have created an interparticle interaction potential for liquid alkali metals using ab-initio simulations and machine learning. The resulting family of potentials was tested by molecular dynamics simulation, in which the liquid metals were heated to the melting point and the resulting system was then averaged. The simulation results show that near the melting point, the radial distribution function and the static structure factor are reproduced. This results indicates that the principle of corresponding states is fulfilled in liquid alkali metals.

Published: May 2022

Abstract
In this study, we performed the molecular dynamics simulation of the binary Ni62Nb38 alloy at heating from 300 K to 9000 K. The temperature dependences of the density and the fraction of liquid atoms were calculated. The boiling temperature of the system is determined. It has been established that near the temperature 7000 K the system undergoes phase transition from liquid to gas phase. It is shown that near the boiling temperature, the molten metal forms a branched structure. The obtained results made it possible to estimate the region of the liquid phase and to determine the probable scenario for the occurrence of structural changes near the boiling point.
