An enhanced expanding and shift sparse array based on the coprime array and nested array
Authors: Qin Caihui , Yang Ling , Dang Jingxin , Dang Bo , Zhou Yan 
Published: October 2023

AbstractIn recent years, sparse arrays based on the fourth‐order difference coarray (FODCA) have received increased research attention due to their small number of array elements and large consecutive virtual arrays. The expanding and shift structure based on the nested array (NA) and coprime array (CPA) (EAS‐NA‐CPA) is the representative one. The EAS‐NA‐CPA comprises two sparse subarrays, wherein the NA is expanded and shifted according to the second‐order difference coarray of the CPA. Although the number of consecutive elements is large, there are many redundant elements in the FODCA of the EAS‐NA‐CPA. To decrease the number of redundant elements and increase the number of consecutive elements in the FODCA, the authors proposed the enhanced EAS‐NA‐CPA (EEAS‐NA‐CPA). Compared with the original EAS‐NA‐CPA, the EEAS‐NA‐CPA increases the adjacent physical sensor spacing further by using more fourth‐order cross‐correlation coarrays in the FODCA, which are not considered in the original EAS‐NA‐CPA. By performing a theoretical analysis of the FODCA provided by the proposed EEAS‐NA‐CPA, the sensor spacing in the expanded NA was further increased to obtain a larger number of consecutive elements compared with the original EAS‐NA‐CPA. Furthermore, the relationship between the number of physical sensors and corresponding number of consecutive elements provided by the FODCA was explicitly expressed. Experimental simulations were conducted to verify the effectiveness of the proposed sparse array for the fourth‐order cumulant‐based direction of arrival estimation.
ALMA detection of CO rotational line emission in red supergiant stars of the massive young star cluster RSGC1

Published: October 2023

Context.The fate of stars largely depends on the amount of mass lost during the end stages of evolution. For single stars with an initial mass between ∼8–30M⊙, most mass is lost during the red supergiant (RSG) phase, when stellar winds deplete the H-rich envelope. However, the RSG mass-loss rate (Ṁ) is poorly understood theoretically, and so stellar evolution models rely on empirically derived mass-loss rate prescriptions. However, it has been shown that these empirical relations differ largely, with differences up to 2 orders of magnitude.Aims.We aim to derive a new mass-loss rate prescription for RSGs that is not afflicted with some uncertainties inherent in preceding studies.Methods.We have observed CO rotational line emission towards a sample of RSGs in the open cluster RSGC1 that all are of a similar initial mass. The ALMA CO(2–1) line detections allowed us to retrieve the gas mass-loss rates (ṀCO). In contrast to mass-loss rates derived from the analysis of dust spectral features (ṀSED), the data allowed us a direct determination of the wind velocity and no uncertain dust-to-gas correction factor was needed.Results.Five RSGs in RSGC1 have been detected in CO(2–1). The retrievedṀCOvalues are systematically lower thanṀSED. Although only five RSGs in RSGC1 have been detected, the data allow us to propose a new mass-loss rate relation for M-type red supergiants with effective temperatures between ∼3200 and 3800 K that is dependent on the luminosity and initial mass, and that is valid during the phase where nuclear burning determines the evolution along the RSG branch. The new mass-loss rate relation is based on the newṀCOvalues for the RSGs in RSGC1 and on priorṀSEDvalues for RSGs in four clusters, including RSGC1. The newṀ-prescription yields a good prediction for the mass-loss rate of some well-known Galactic RSGs that are observed in multiple CO rotational lines, includingαOri,μCep and VX Sgr. Moreover, there are indications that a stronger, potentially eruptive, mass-loss process is occurring during some fraction of the RSG lifetime, suggesting that RSGs might experience a phase change in mass loss leading to the wind mass-loss rate dominating the RSG evolution at that stage.Conclusions.Implementing a lower mass-loss rate in evolution codes for massive stars has important consequences as to the nature of their end-state. A reduction of the RSG mass-loss rate implies that quiescent RSG mass loss is not enough to strip a single star’s hydrogen-rich envelope. Upon core collapse such single stars would explode as RSGs. Mass-loss rates of order ∼6 times higher would be needed to strip the H-rich envelope and produce a Wolf-Rayet star while evolving back to the blue side of the Hertzsprung–Russell diagram. Future observations of a larger sample of RSGs in open clusters should allow a more stringent determination of theṀCO–luminosity relation and a sharper diagnostic as to when the phase change in mass loss is occurring.

Vergleich zweier Bandagetechniken bei sekundärem Armlymphödem nach Brustkrebs
Authors: Walder Sibylle , Betschart Martina , Benz Thomas 
Published: October 2023

Zusammenfassung
Hintergrund Das Armlymphödem ist eine mögliche Folge bei axillärer Lymphknotenentfernung aufgrund von Brustkrebs und führt zu Einschränkungen im Alltag sowie der Lebensqualität. Aktuell ist unklar, durch welches Bandagematerial während der komplexen physikalischen Entstauungstherapie die größere Volumenreduktion bei bestmöglicher Lebensqualität erfolgen kann.
Ziel Beantwortung der Frage, ob das Zweilagen-Kompressionssystem „3M™ Coban™ 2 Lite“ bei Patientinnen mit sekundärem Armlymphödem innerhalb einer einwöchigen Intensivphase eine größere prozentuale Ödemvolumenreduktion bewirken kann als die Therapie mit klassischen Kurzzugbinden. Zudem wurde evaluiert, welches der beiden Materialien mit einem besseren Therapieempfinden und einer höheren Lebensqualität verknüpft ist.
Methode Von März 2021 bis November 2021 wurden im Kantonsspital Winterthur Intensivphasen bei Frauen mit sekundärem Lymphödem durchgeführt. Im Rahmen der Standardtherapie erhielten sie während einer Woche entweder 3-mal pro Woche eine Coban-Lite-Bandage oder täglich eine klassische Kurzzugbandage. Ausgewertet wurde die prozentuale Ödemvolumenreduktion, die Lebensqualität und das Therapieempfinden nach einer Woche Therapie.
Ergebnisse Daten von 34 Patientinnen, jeweils 17 pro Gruppe, wurden ausgewertet. Die prozentuale Ödemvolumenreduktion von 55,1 % in der Coban-Lite-Gruppe und 35,0 % in der Klassische-Bandage-Gruppe (p = 0,067; 95 % KI [−0,646; 28,809]) sowie die Lebensqualität (p = 0,202; 95 % KI [−1,11; 0,22]) unterschieden sich in beiden Gruppen nicht signifikant voneinander. Das Therapieempfinden war jedoch in der Coban-Lite-Gruppe signifikant besser als in der Klassische-Bandage-Gruppe (p = 0,004; 95 % KI [−117; −0,17]) und wies eine mittlere Effektstärke (r = 0,488) auf.
Schlussfolgerung Die Anwendung der beiden Bandagetechniken zeigten keinen statistisch signifikanten Gruppenunterschied hinsichtlich der Ödemvolumenreduktion nach einer Woche. Während dieser Zeit wurden mit der Coban-Lite-Bandage weniger Therapiesitzungen durchgeführt als mit der klassischen Bandage. Zudem erzielte die Coban-Lite-Bandage beim Therapieempfinden ein signifikant besseres Ergebnis.

ZusammenfassungDer Tod eines Menschen und die Todesumstände werden in Deutschland auf
der Todesbescheinigung dokumentiert. Der Weg des Leichnams zur Bestattung sowie
die Qualität der Todesursachenstatistik werden maßgeblich durch
die Angaben in der amtlichen Todesbescheinigung beeinflusst. Die
Qualität der Angaben in den Todesbescheinigungen wird immer wieder
bemängelt. Ziel der vorliegenden Studie war es, typische Fehlerquellen
in Todesbescheinigungen zu identifizieren und Hinweise zu erhalten, ob
qualitative Unterschiede zwischen den im ambulanten und stationären
Bereich ausgefüllten Todesbescheinigungen bestehen. Es erfolgte eine
retrospektive Auswertung von 218 Todesbescheinigungen von Todesfällen,
die im Rahmen einer zweiten Leichenschau vor der Feuerbestattung von der
Rechtsmedizin untersucht wurden. Davon wurden 118 Todesbescheinigungen im
Krankenhaus (hospitale Leichenschau) und 100 Todesbescheinigungen ambulant durch
den zuständigen Hausarzt/die zuständige
Hausärztin oder eine(n) im ambulanten Sektor diensthabende(n)
Arzt/Ärztin ausgestellt. Bis auf eine ambulant ausgestellte
Todesbescheinigung waren alle Dokumente lesbar. Die Angaben zur Grunderkrankung
waren plausibel. Über ein Drittel der Epikrisen waren ohne nennenswerten
Erkenntnisgewinn oder gar nicht ausgefüllt. Die Eintragung zu den
unmittelbaren Todesursachen in dem dafür vorgesehenen Feld auf der
Todesbescheinigung (Ia in der Kausalkette) waren in gut einem Drittel der
Fälle unzureichend. Die Fehlerrate bei den Eintragungen war im
ambulanten Bereich höher als bei hospitalen Sterbefällen. Es
gilt deshalb für die Zukunft, durch Fort- und
Weiterbildungsveranstaltungen auf die besondere Situation einer Leichenschau
vorzubereiten und die Bedeutung der dabei festgelegten Diagnosen zu vermitteln,
um diese vermeidbaren Fehlerquellen abzustellen.

Abstract
Purpose To assess splenic involvement using B-mode ultrasound (US) and contrast-enhanced ultrasound (CEUS) compared with standard imaging with contrast-enhanced computerized tomography (CT) / 18-fluorodeoxyglucose positron-emission tomography (PET-CT) in patients with Hodgkin lymphoma.
Materials and Methods Imaging data from 112 patients from 12/2003 to 10/2022 with histologically confirmed Hodgkin lymphoma during staging or relapse were analyzed for splenic lymphoma involvement. In all patients, standard imaging (CT/PET-CT), along with B-mode US and CEUS examinations, was performed. Evidence of focal splenic lesions (FSLs) found by imaging procedures was suggestive of splenic involvement. Follow-up imaging was performed in each patient after treatment, and treatment response indicated definitive splenic involvement.
Results 40 patients (35.7%) were identified by imaging modalities as having splenic involvement, which was confirmed by response during follow-up. Standard CT/PET-CT imaging detected splenic involvement in 36/112 patients (32.1%). FSLs were detected with B-mode US in 38 patients (33.9%) and CEUS in 36 patients (32.1%). The sensitivity of standard imaging, B-mode US, and CEUS was 90%, 95%, and 90%, respectively.
Conclusion B-mode US examination is a diagnostic method used in addition to standard imaging for the detection of splenic involvement in Hodgkin lymphoma. CEUS does not provide additional benefit compared to B-mode US and the standard reference procedure.
Calculated solvent reorganization entropies, free energies, and fluctuations of the energy gaps for intramolecular electron transfer and excitation of the solvatochromic dye B30
Authors: Parson William W. , Burda Clemens 
Published: October 2023

Intramolecular electron transfer between two biphenyl groups linked by an androstane spacer and excitation of the pyridinium-N-phenolate betaine dye B30 to the first excited singlet state are studied by quantum/classical molecular-dynamics simulations at temperatures between 150 and 300 K in solvents with a range of polarities. Temperature dependences of the solvent reorganization energies, free energies, entropies, and the inhomogeneous broadening of B30’s absorption band are examined. The variances of fluctuations of the energy gap between the reactant and product states do not have the direct proportionality to temperature that often is assumed to hold. An explanation for the observations is suggested.
Effect of helium on thermal transport properties in single- and bi-crystals of Ni: a study based on molecular dynamics
Authors: Sharma Saurabh S , Parashar Avinash 
Published: October 2023

Abstract
Nuclear structures are prone to irradiation-induced defects that make them susceptible to alternation in mechanical and thermal properties. The transmutation of Ni to insoluble He atoms is considered to be responsible for the embrittlement of Ni. Helium bubbles are deemed responsible for the deterioration of mechanical and thermal properties of the Ni crystal, and this should be studied in detail to predict the lifespan of ageing nuclear structures. The aim of this article is to study the effect of helium on the thermal transport phenomenon in single- and bi-crystals of Ni. Molecular dynamics-based simulations in conjunction with a hybrid force field are performed to study the effect of a helium bubble on the thermal transport phenomenon in Ni crystals. These simulations are further extended to study the impact of symmetrical tilt grain boundaries (STGB) in conjunction with the doping of helium atoms on the thermal transport phenomenon in bi-crystal Ni. The effect of helium concentration in the bubble significantly alters the thermal transport in single-crystal Ni. The STGB configuration also introduces interfacial thermal resistance as a function of the misorientation angle. The helium-doped grain boundaries further increase the resistance to phonon movement and increase Kapitza resistance. The increase in Kapitza resistance is more dominant in higher misorientation angle grain boundaries.
Vortex wake patterns in superfluid 4He
Authors: Kolomeisky Eugene B 
Published: October 2023

Abstract
Excitations in the form of quantized vortex rings are known to exist in superfluid 4He at energies and momenta exceeding those of the Landau phonon–roton spectrum. They form a vortex branch of elementary excitations spectrum which is disconnected from the Landau spectrum. Interference of vortex ring excitations determines wake patterns due to uniformly traveling sources in bulk superfluid at low speeds and pressures. The dispersion law of these excitations resembles that of gravity waves on deep water with infrared wave number cutoff. As a result, vortex wake patterns featuring elements of the Kelvin ship wake are predicted. Specifically, at lowest speeds the pattern with fully developed transverse and diverging wavefronts is present. At intermediate speeds transverse wavefronts are absent within a cone whose opening angle increases with the source velocity. At largest speeds only diverging wavefronts confined within a cone whose opening angle decreases with the source velocity are found. When experimentally observed, these changes in appearance of wake patterns serve as indicators of the beginning part of the vortex branch of elementary excitations.

The Fe vacancies caused by the Fe deficiency is beneficial to the improvement of both critical temperature and activation energy, while with the increase of the Fe content, the superconductivity degrades because of the introduction of the interstitial Fe and the planar defects.

Authors: Chen Liwei , Song Dianyang , Zhang Shuyuan 
Published: October 2023

Abstract
When a natural disaster occurs, ensuring timely and efficient delivery of emergency supplies to every affected location is crucial in mitigate the losses caused by the disaster. This study focuses on the distributing emergency supplies to heterogeneous multi-drone (UAV) swarms in the post-disaster scenario. Given the known distribution stations and disaster locations, a model is proposed that enables multiple drones to distribute various emergency supplies to multiple disaster zones. The model incorporates multiple objective constraints, including UAV range, priority of emergency goods, and UAV losses, resulting in a multi-objective optimization problem. To enhance the solving ability of genetic algorithm, we improve genetic algorithm by introducing adaptive cross operators, and its feasibility is compared with traditional genetic algorithms. Simulation experiments demonstrate that the improved genetic algorithm is significantly superior to traditional genetic algorithms in solving the optimal allocation scheme, thus providing a scientific basis for decision-making in emergency supply distribution.
The Upper Bound Estimation of Abelian Integral for a Class of Quadratic Reversible System under Small Perturbations
Authors: Zhan Yuangen 
Published: October 2023

Abstract
In this article, by using the Riccati equation method, we investigate the maximal values of the isolated zeros of the Abelian integral for a set of quadratic reversible systems (r11) that belong to genus one, while experiencing varying 3rd, 2nd, and 1st-polynomial perturbations. Specifically, we aimed to find the upper bound for the maximal zeros of the system’s limit cycle (a special dynamic behavior in a stable state, characterized by the existence of specific periodic orbits). We know that the Abelian integral is a function of h, so when studying the maximal zeros of the function related to h, we not only consider the highest degree of the relevant function but also take into account the parity of the function and the range of values of h. Then through variable substitution, a smaller upper bound can be obtained: our findings show that the maximal values of the isolated zeros count under varying 3rd, 2nd, and 1st-polynomial perturbations is 12, improving upon previous results where the upper bound was 34 for the 3rd polynomial perturbation and 22 for the 2nd and 1st polynomial perturbations. This study represents an improvement upon previous research.
The fitting of roundabout model with gradient-based minimization
Authors: Cheah Yuat Hoong , Yeak Su Hoe 
Published: October 2023

Abstract
The objective of this research is to create an appropriate roundabout model for all countries. To date, the four-arm roundabout macroscopic model has been created. In order to ensure the feasibility and suitability of the model for all countries, the fitting process must be implemented since the speed of vehicles varies in each country. Thus, the parameter estimation on the rate of exiting roundabout is to be determined because the mean speed of vehicles is related to the rate of exiting the roundabout. In the minimization process, we have proposed an efficient and reliable framework as it includes the calculation of gradients used in minimization so called the user supplied-gradient minimization, as compared to non-user supplied-gradient minimization. The including of the calculation of gradient is to produce more accurate results by the built-in MATLAB minimization routine for parameter fitting. In this research, five pseudo experiments with numerous parameters are carried out. The rate of exiting the roundabout is set initially in order to compute the Total Travel Time and Total Waiting Time. The simulation showed a highly converged and accurate solution by the user supplied-gradient minimization. Lastly, this parameter estimation can be implemented that will enable the roundabout model to be applied worldwide if there is actual data for Total Travel Time and Total Waiting Time.
Uncertainty analysis of potential population exposure within the coastal lowlands of mainland China

Published: October 2023

Abstract
With accelerating global sea level rise driven by climate change, accurate estimates of potential population exposure (PPE) within the low-elevation coastal zones (LECZ) are critical for coastal planning and assessing the benefits of climate mitigation. Multiple digital elevation models (DEM) and population grid datasets have been used for the PPE assessment of coastal lowlands. However, the uncertainty arising from differences in data sources and production methods results in poorly guided estimates. In this study, four global DEM and five population datasets were used to estimate the PPE in the LECZ of China and to assess the uncertainty of PPE estimation. Based on the DEM and population grid with the best accuracy, we found that more than 13.82% of China’s residents lived in the LECZ in 2010. Different DEM-population combinations yielded significantly different PPE estimates, ranging between 3.59–24.61 million and 31.56–112.24 million people in the LECZ below 1 m and 4 m elevation, respectively. The satellite Lidar-based DEM improves the estimates of the LECZ and obtains the PPE within LECZ below 4 m elevation that far exceeds those of other DEM datasets. The usage of WorldPop and LandScan population datasets leads to an underestimation of PPE within the LECZ of China. In contrast, integrating more geospatial big data helps generate better population grids, thus reducing the uncertainty of coastal PPE estimates. There is still a need to improve the availability and accuracy of coastal geospatial data and to deepen the understanding of coastal vulnerability.
