Authors: Karampinis Ioannis , Gerken Andreas , Reissfelder Christoph , Nowak Kai , Jakob Jens 
Published: August 2022

Zusammenfassung
Hintergrund Die wichtigsten Morbiditäten der systematischen inguinalen und axillären Lymphknotendissektion sind Lymphfisteln und Serome. Die intraoperative, fluoreszenzgesteuerte
Versiegelung der Lymphgefäße könnte die Häufigkeit dieser postoperativen Komplikationen verringern.
Methoden Vor der Lymphadenektomie erfolgte die Intrakutaninjektion von Indocyanin-Farbstoff im Bereich der distalen Extremität. Die Lymphadenektomie wurde nach Standardprotokollen
durchgeführt. Während des gesamten Eingriffs wurde Nahinfrarot-Bildgebung eingesetzt, und es wurde eine fluoreszenzgesteuerte Lymphgefäßversiegelung in Echtzeit durchgeführt
(Videopräsentation).
Ergebnisse Die fluoreszenzgesteuerte Lymphgefäßversiegelung wurde bei 3 Patienten durchgeführt, die sich einer axillären systematischen Lymphknotendissektion unterzogen. Nach der
Injektion des Fluoreszenzfarbstoffs traten keine unerwünschten Ereignisse auf. Alle Patienten konnten ohne Wundkomplikationen entlassen werden.
Schlussfolgerung Die fluoreszenzgesteuerte Lymphgefäßversiegelung könnte eine vielversprechende neue Technik zur Verhinderung von Lymphfisteln nach systematischer Lymphadenektomie
sein.
The economic imperatives for technology enabled wellness centered healthcare
Authors: Jones Graham B. , Wright Justin M. 
Published: August 2022

AbstractA 2020 World Health Organization report underscored the impact of rising healthcare spending globally and questioned the long-term economic sustainability of current funding models. Increases in costs associated with care of late-stage irreversible diseases and the increasing prevalence of debilitating neurodegenerative disorders, coupled with increases in life expectancy are likely to overload the healthcare systems in many nations within the next decade if not addressed. One option for sustainability of the healthcare system is a change in emphasis from illness to wellness centered care. An attractive model is the P4 (Predictive, Preventative, Personalized and Participatory) medicine approach. Recent advances in connected health technology can help accelerate this transition; they offer prediction, diagnosis, and monitoring of health-related parameters. We explain how to integrate such technologies with conventional approaches and guide public health policy toward wellness-based care models and strategies to relieve the escalating economic burdens of managed care.
The AuSc, AuTi, and AuFe molecules: Determination of the bond energies by Knudsen effusion mass spectrometry experiments combined with ab initio calculations
Authors: Lucci Elena , Giarrusso Sara , Gigli Guido , Ciccioli Andrea 
Published: August 2022

The AuTi gaseous molecule was for the first time identified in vapors produced at high temperature from a gold–titanium alloy. The homogeneous equilibria AuTi(g) = Au(g) + Ti(g) (direct dissociation) and AuTi(g) + Au(g) = Au2(g) + Ti(g) (isomolecular exchange) were studied by Knudsen effusion mass spectrometry in the temperature range 2111–2229 K. The so determined equilibrium constants were treated by the “third-law method” of thermodynamic analysis, integrated with theoretical calculations, and the dissociation energy at 0 K was derived as D0K° (AuTi) = 241.0 ± 5.2 kJ/mol. A similar investigation was carried out for the AuSc and AuFe species, whose dissociation energies were previously reported with large uncertainties. The direct dissociation and the isomolecular exchange with the Au2 dimer were studied in the 1969–2274 and 1842–2092 K ranges for AuSc and AuFe, respectively, and the dissociation energies derived as D0K° (AuSc) = 240.4 ± 6.0 and D0K° (AuFe) = 186.2 ± 4.2 kJ/mol. The experimental bond energies are compared with those calculated here by coupled cluster with single, double, and perturbative triple excitations with the correlation-consistent basis sets cc-pVXZ(-PP) and cc-pwCVXZ(-PP) (with X = T, Q, 5), also in the limit of complete basis set, and with those from complete active space self-consistent field-multi-reference configuration interaction calculations, recently available in the literature. The stronger bond of AuTi compared to AuFe parallels the trend observed in monochlorides. This analogy is shown to be more generally observed in the AuM and MCl diatomic series (with M = first row transition metal), in accordance with a picture of “pseudo-halogen” bonding behavior of gold.

In this study, we describe the design, fabrication, and characterization of a cross-shaped structure reflective broadband THz polarization converter. The operating bandwidth of the proposed polarization converter was in the range of 0.8–1.6 THz. The polarization conversion rate (PCR) exceeded 85% in the frequency range of 1.07–1.35 THz and was as high as 91% at 1.35 THz. The cross PCR value exceeded 85% in the frequency range of 1.05–1.35 THz and reached a maximum value of 91%. The performance characteristics (bandwidth and PCR) of the proposed polarization converter were compared with those of similar previously reported devices, and the results indicated that the proposed polarization converter exhibits better performance. The proposed THz polarization converter is suitable for a wide range of applications in communication and polarization manipulation devices.

Published: August 2022

The voltage-controlled magnetic anisotropy (VCMA) effect has been proposed as an energy efficient approach for controlling the direction of magnetization. To demonstrate the scalability of a voltage-controlled magnetoresistive random access memory, we need to optimize the perpendicular magnetic anisotropy (PMA), tunnel magnetoresistance (TMR), and VCMA properties. Here, we performed a systematic investigation of the effects of inserting a post-oxidized MgAl layer on PMA, TMR, and VCMA in epitaxial magnetic tunnel junctions (MTJs). PMA and TMR have substantial dependences on the thickness of the MgAl layer, and their maximum values occurred when the MgAl layer was 0.20 nm thick, resulting in threefold and twofold increases in the PMA energy and TMR ratio, respectively, compared with the case without a MgAl layer. On the other hand, the VCMA coefficient increased as the MgAl layer thickness decreased and had a maximum value of −350 fJ/Vm when the MgAl layer was 0.16 nm thick, suggesting that the weakly oxidized interface provides a larger VCMA effect. Interface engineering using a post-oxidized ultrathin MgAl layer provides us with a valuable technique for precisely controlling the PMA, TMR, and VCMA properties of voltage-controlled MTJs.
Self-formation of InAs/InGaAsSb type-II superlattice structures on InP substrates by MBE and their application to mid-infrared LEDs
Authors: Uno Kou , Iijima Naoto , Miyashita Naoya , Yamaguchi Koichi 
Published: August 2022

InAs/InGaAsSb type-II superlattice structures (SLSs) were spontaneously formed by the molecular beam epitaxy of InAs/GaAs0.86Sb0.14 SLSs on InP substrates. The strain due to lattice mismatch between InAs and GaAs0.86Sb0.14 induced two exchange reactions of In–Ga and As–Sb at both InAs/GaAs0.86Sb0.14 heterointerfaces, resulting in the strain relaxation and the self-formation of InAs/InGaAsSb type-II SLS. By energy dispersive x-ray spectroscopy analysis, the mixed crystal composition of the InGaAsSb layer was determined to be approximately In0.8Ga0.2As0.9Sb0.1. Electroluminescence spectra of LEDs, including the self-formed InAs/In0.8Ga0.2As0.9Sb0.1 2.5-periodic SLS, showed double peaks of 2.6 and 3.2 µm at 15 K. The luminescence spectrum was based on two transition mechanisms of type-I transition in InAs and type-II transition between InAs and InGaAsSb. The experimental results of luminescence spectra were supported by theoretical calculations. The 3.3 µm emission was maintained above 220 K.

Published: August 2022

Abstract
Although the ion temperature can considerably affect bulk plasma parameters and ion angle distribution functions arriving at the substrate, limited experiments have been conducted on this phenomenon because ion temperature measurement is difficult. Furthermore, only a few simulations have been performed under specific conditions. Therefore, in this study, a novel method was developed to calculate the ion temperature using a global model. The spatially averaged ion temperature equation was derived by integrating the ion temperature over space. Continuity and electron temperature equations were used in a self-consistent manner to solve the equation. We investigated radio-frequency inductively coupled Ar, N2, and Cl2 discharges in the pressure range of 5–20 mTorr and power range of 200–1000 W. The obtained results were highly consistent with experimental and two-dimensional simulation results.

Published: August 2022

Abstract
Herein, the interaction and relative motion of two circular magnetic particles in a static flow and planar Poiseuille flow is investigated via numerical simulation. A two-dimensional numerical model is constructed based on Maxwell’s finite element method, fully considering the interactions between particles and particles, particles and magnetic fields, and particles and flow fields. First, the motion state and action mechanism of the magnetic particles in contact state in the static fluid are analyzed under a vertical magnetic field; then, the simulation results are verified via experiments. Based on the motion state of the magnetic particles in the planar Poiseuille flow, the feasibility of effectively controlling the trajectory of magnetic particles in the planar Poiseuille flow using a magnetic field is discussed. In the static flow, the vertical magnetic field was unable to separate the contacting magnetic particles; thus, the magnetic field cannot effectively control magnetic particles in static flows. In the planar Poiseuille flow, the free contact and separation of magnetic particles was effectively controlled by the combined action of the magnetic field and the fluid. This study provides insights into the interactions among magnetic particles in static flows and summarizes a set of methods for effectively controlling two circular magnetic particles.
Cornell potential in generalized soft wall holographic model
Authors: Afonin Sergey , Solomko Timofey 
Published: August 2022

Abstract
We derive and analyze the confinement potential of the Cornell type within the framework of the generalized soft wall holographic model that includes a parameter controlling the intercept of the linear Regge spectrum. In the phenomenology of Regge trajectories, this parameter is very important for the quantitative description of experimental data. Our analysis shows that the ‘linear plus Coulomb’ confinement potential obtained in the scalar channel is quantitatively consistent with the phenomenology and lattice simulations while the agreement in the vector channel is qualitative only. This result indicates the key role of the vacuum scalar sector in the formation of the confinement potential. As a by-product the overall consistency of our holographic description of confinement potential seems to confirm the glueball nature of the scalar meson f
0(1500).

Published: August 2022

Abstract
Wheel measurement and positioning technology is an important technology in vehicle production, and is of great importance for the safety of vehicles. At present, visual measurement and other methods are widely used in automotive production and inspection, but these methods are limited to the measurement of regular-sized vehicles. There is no effective solution to the problem of wheel alignment for large special-purpose vehicles with multiple tires. In order to solve the wheel positioning problem of large-size special-purpose vehicles, this paper designs a vision measurement system for wheel parameters in large scenes by combining vision sensors with linear motion guides to extend the vision measurement range and complete the global calibration of multiple-vision sensors with the help of laser trackers and self-researched stereo targets. This paper proposes an Elementary–Advance global calibration algorithm to improve the accuracy of coordinate system conversion during global calibration. This paper establishes a correction model for the measurement errors that exist in the initial global calibration process, and iterates the objective function to optimize the coordinate system conversion parameters between multiple vision sensors to improve the measurement accuracy of the system. The experimental results show that the goodness of fit and the accuracy of fit for the feature cylinder are 98.31% and 99.03% based on the global calibration method of this paper. The standard deviation of measurements for the standard ruler of the Inva alloy is less than 0.391 mm in the large dimensional range of 6050 mm × 3500 mm × 800 mm. Finally, by comparing the measurement results with the TrukCam four-wheel alignment instrument, the feasibility of the visual measurement system designed in this paper for large scenarios of wheel parameters is verified, and the measurement accuracy requirements for four-wheel alignment of special-purpose vehicles are met.
Formation and propagation of cracks in RRP Nb3Sn wires studied by deep learning applied to x-ray tomography
Authors: Bagni Tommaso , Mauro Diego , Majkut Marta , Rack Alexander , Senatore Carmine 
Published: August 2022

Abstract
This paper reports a novel non-destructive and non-invasive method to investigate crack formation and propagation in high-performance Nb3Sn wires by combining x-ray tomography and deep learning networks. The next generation of high field magnet applications relies on the development of new Nb3Sn wires capable to withstand the large stresses generated by Lorentz forces during magnets operation. These stresses can cause a permanent reduction of the transport properties generated by residual deformation of the Nb3Sn crystal lattice as well as the formation of cracks in the brittle Nb3Sn filaments. Studies for the development of the high luminosity LHC (HL-LHC) upgrade showed that nominal transverse compressive stresses above 150 MPa may be sufficient to generate cracks in the wires. In the case of fusion magnets, wires experience periodic bending due to the electro-magnetic cycles of the reactor which over time may induce wire deformation and filament cracks. Therefore, it has become essential to develop a quantitative method for the characterization of crack formation and propagation under compressive loads. The x-ray tomographic data of a series of restacked-rod-process (RRP) Nb3Sn wires was acquired at the micro-tomography beamline ID19 of the European Synchrotron Radiation Facility (ESRF), after intentionally inducing a broad spectrum of cracks in the Nb3Sn sub-elements. The samples were submitted to transvers compressive stresses, with and without epoxy impregnation, at different pressures, up to 238 MPa. The resulting tomographic images were analysed by means of deep learning semantic segmentation networks, using U-net, a convolutional neural network (CNN), to identify and segment cracks inside the wires. The trained CNN was able to analyse large volumes of tomographic data, thus enabling a systematic approach for investigating the mechanical damages in Nb3Sn wires. We will show the complete three-dimensional reconstruction of various cracks and discuss their impact on the electro-mechanical performance of the analysed wires.
Vortex shedding frequency of a moving obstacle in a Bose–Einstein condensate
Authors: Lim Younghoon , Lee Yangheon , Goo Junhong , Bae Dalmin , Shin Y 
Published: August 2022

Abstract
We experimentally investigate the periodic vortex shedding dynamics in a highly oblate Bose–Einstein condensate using a moving penetrable Gaussian obstacle. The shedding frequency f
v is measured as a function of the obstacle velocity v and characterized by a linear relationship of f
v = a(v − v
c) with v
c being the critical velocity. The proportionality constant a is linearly decreased with a decrease in the obstacle strength, whereas v
c approaches the speed of sound. When the obstacle size increases, both a and v
c are decreased. We discuss a possible association of a with the Strouhal number in the context of universal shedding dynamics of a superfluid. The critical vortex shedding is further investigated for an oscillating obstacle and found to be consistent with the measured f
v. When the obstacle’s maximum velocity exceeds v
c but its oscillation amplitude is not large enough to create a vortex dipole, we observe that vortices are generated in the low-density boundary region of the trapped condensate, which is attributed to the phonon emission from the oscillating obstacle.

Published: August 2022

Abstract
Optomagnonics is a good platform for the interplay of radio frequency and optical signals, which are the primary communication carriers in the present day. On the basis of optomagnonics, we provide a multi-scale method for analyzing its behavior, including frequency comb and RoF chaotic synchronization at the microwave scale. Adjusting the pump light intensity permits the transition of RoF signals between harmonics, frequency combs, and chaotic movements. The dual optomagnonical device enables the synchronization of RoF signals between different cavities. Our study will contribute to the use of multiscale electromagnetic wave coupling in both conventional and quantum information applications.
Electrical characterization of the 2 × 6 × n cobweb cascaded resistor network model by the improved recursion-transform method

Published: August 2022

Abstract
Since the cobweb model combines the properties of several network topologies, the cobweb resistor network based on the cobweb model has aroused the interest of scholars. However, owing to the complicated structure of the cobweb cascaded resistor network, it is very challenging to solve with conventional approaches. To address this issue, an improved recursion-transform approach was employed. The electrical characterization of the 2 × 6 × n cobweb cascade resistor network model was studied in this paper. Firstly, the equivalent circuit of the resistor network to be solved was found. Secondly, the recursive equation of the equivalent circuit was constructed. Then, the recursive equation was linearized. Finally, the equivalent resistance of the resistor network was obtained by solving the linear recursive equation. This approach significantly reduces the computation procedure because it adopts the scheme of simplifying the circuit first, then establishing the equation and solving it. The findings indicate that the equivalent resistances between the two nodes of this resistor network change with the change of the order n. When n tends to infinity, these equivalent resistances will have definite convergence values. The calculation results show that these equivalent resistances are already very close to their convergence values, respectively, when n takes 7 or 8.

Published: August 2022

Abstract
The current work concerns with the effects of cupper sulfide (CuS) buffer layer on morphological, structural and optical properties of tellurium dioxide (TeO2) nanostructured thin films synthesized by vapor transport method. Single crystalline tetragonal TeO2 crystallographic phase with enhanced peak intensity and crystallinity for CuS/TeO2 film are observed by x-ray diffraction analysis. Scanning electron microscopy examinations revealed small rod-like morphology for TeO2 and randomly oriented nanowires morphology for CuS/TeO2 samples. The estimated optical band gap energies were 3.78 and 3.63 eV for TeO2 and CuS/TeO2 nanostructured films, respectively. The photoluminescence of CuS/TeO2 film was enhanced and red-shifted from 450 to 455 nm by the presence of CuS layer. The effective charge carrier life times were 0.14 ns and 1.92 ns for TeO2 and CuS/TeO2 films, respectively. These results could be beneficial for optoelectronic devices such as light emitting devices.

Experimental studying the propagation and absorption of electromagnetic waves on various rock-forming minerals in Uzbekistan
Authors: Saydalimov A S 
Published: August 2022

AbstractThe nature of wave propagation often depends on the frequency and on the type of radiation used. The main goal of these technologies is to bring into development low-permeability isolated zones of the reservoir by exposing them to elastic waves that attenuate in high-permeability sections of the reservoir, but propagate over considerable distances and with sufficient intensity to excite low-permeability sections of the reservoir. In this paper, a more in-depth study of the propagation and absorption of electromagnetic waves through various minerals contained in rock was considered, in particular, the behavior of electromagnetic waves through rock with different moisture contents (water molecules) and clay particles (aluminosilicates) was studied. It was found that the radiative power reached the highest value at 0.01 distance, which was 506 at 10% water content, followed by 505 at 20% water content, 504 at 30% water content, 502 at 40% water content, 500 at 50% water content, and it was 498 when water content was 60%.
