Published: June 2022

Objective The aim of the study is to evaluate the use of a bipolar electrocautery device for complete salpingectomy at cesarean to improve procedure completion rates, operative time, and surgeon reported satisfaction as compared with standard bilateral tubal ligation (BTL) and suture-cut-tie salpingectomy.
Study Design This is a prospective cohort study of women undergoing planned, non-emergent cesarean with desired sterilization with complete salpingectomy utilizing a bipolar electrocautery device. Study patients were compared with historic controls from a randomized controlled trial (RCT) of complete salpingectomy via suture-cut-tie method versus BTL conducted at our institution (SCORE trial, NCT02374827). Outcomes were compared with groups from the original RCT.
Results Thirty-nine women were consecutively enrolled (12/2018–11/2019) into the device arm of the study and compared with the original SCORE cohort (n = 40 BTL, n = 40 salpingectomy without a device). Salpingectomy performance with the bipolar electrocautery device was successfully completed in 100% (39/39) of enrolled women, with one device failure requiring the use of a second device, as compared with 95% (38/40) in the BTL (p = 0.49) and 67.5% (27/40) in salpingectomies without a device (p < 0.001). Mean operative time of sterilization procedure alone demonstrated device use as having the shortest operative time of all (device salpingectomy 5.0 ± 3.6 vs. no device 18.5 ± 8.3 minutes, p < 0.001; and vs. BTL 6.9 ± 5.0, p = 0.032). Mean sterilization procedure endoscopic band ligation (EBL) was demonstrated to be significantly different between each group, least amongst BTL followed by device (6.3 ± 4.8 vs. 8.4 ± 24.8, p < 0.001), and most by suture-cut-tie method (17.7 ± 14.3, p < 0.001 compared with device). Surgeon reported attitudes of complete salpingectomy performance in general practice outside an academic setting was greater with a device than without (79.5 vs. 35.3%; p < 0.001).
Conclusion Use of a bipolar electrocautery device improved operative times and surgeon satisfaction for salpingectomy at cesarean over standard suture ligation. Device use improved surgeon reported outcomes and may improve incorporation of complete salpingectomy at cesarean.

Endovascular Aortic Aneurysm Repair: A Narrative Review
Authors: Rehman Zia Ur 
Published: June 2022

AbstractEndovascular aortic aneurysm repair (EVAR) has evolved as minimally invasive method of treating infrarenal abdominal aortic aneurysms (AAA) with perioperatively mortality of less than 1% compared with 5% with open AAA repair as suggested by many randomized control trials. Computed tomography angiography is the imaging of choice for appropriate selection of a patient with EVAR. For patients with unsuitable anatomy, advanced EVARs techniques, such as fenestrated, branch, and chimney EVARs, are also increasingly being offered to patients with equal success. Patients with ruptured AAA are treated with this minimally invasive procedure. Percutaneous EVAR emerged with less of wound-related complications. Endoleaks are the most common complications peculiar to this procedure, and most are preventable by preoperative planning. They are detected on completion angiogram or on the surveillance imaging. This review discusses indications of EVAR, its selection criteria, procedural steps, and common complications associated with this procedure and advanced EVARs.
Revealing the mechanism causing stepwise maximum bounce height changes in a bouncing ball system
Authors: Karube Shu , Uemura Yuki , Kousaka Takuji , Inaba Naohiko 
Published: June 2022

The bouncing ball system is a simple mechanical collision system that has been extensively studied for several decades. It is a fundamental problem in impact dynamics. We studied a traditional bouncing ball system numerically and experimentally and discovered novel bifurcation structures where the maximum height of the bouncing ball with respect to the stationary state increases stepwise nonsmoothly when we increase the frequency of the oscillating table continuously even though the bouncing ball is in chaotic states [Karube et al., Chaos 30, 103111 (2020)]. We attempt to reveal the trick causing the stepwise changes of the maximum heights of the bouncing ball. We focus on the time interval for the ball to take off and land on the oscillating table at which the ball takes the maximum height. Let this time interval be denoted by t-interval. In addition, let the oscillation frequency of the table be denoted by f. The stepwise increases in the maximum heights of the bouncing ball in the stationary states occur when the multiplication of the t-interval and f coincides with integer values. This is the mechanism causing the nonsmooth maximum heights. Furthermore, results that are qualitatively consistent with the numerical ones are verified in the actual bouncing ball system using table tennis ball equipment.

Published: June 2022

This paper describes a new experimental setup designed for the direct measurement of the Rayleigh ratio and Rayleigh scattering length for linear alkylbenzene, a solvent commonly used in liquid scintillator detectors for neutrino experiments. Using the new approach, the perpendicularly polarized Rayleigh ratio was determined to be (4.52 ± 0.28) × 10−6 m−1 sr−1 at 405 nm and (3.82 ± 0.24) × 10−6 m−1 sr−1 at 432 nm, and the corresponding Rayleigh scattering length was LRay = 22.9 ± 0.3(stat.) ± 1.7(sys.) m at 405 nm and LRay = 27.0 ± 0.9(stat.) ± 1.8(sys.) m at 432 nm. These results are consistent with both previous results determined using other experimental strategies and theoretical predictions.

Published: June 2022

Rydberg atoms can serve as an atomic radio frequency receiver for digital and analog information transmission. In this paper, a ladder-type electromagnetically induced transparency system is prepared in a room temperature cesium atomic vapor cell. Microwave electric fields in the Ku band at a frequency of 12.52 GHz and the Ka band at a frequency of 39.80 GHz are used as two-channel communication carriers to demonstrate concurrent information transmission. Analog and digital communications are demonstrated by performing audio and pseudo-random binary sequence signal transmission, respectively. The dynamic range of the proposed system is ∼50 dB, and the communication bandwidth is more than 10 MHz. The obtained results demonstrate the fundamental principles of two- or multi-band communication systems based on different Rydberg final states.

Published: June 2022

Microwave-induced plasma was used to anneal precursor powders containing five metal oxides with carbon and boron carbide as reducing agents, resulting in high entropy boride ceramics. Measurements of hardness, phase structure, and oxidation resistance were investigated. Plasma annealing for 45 min in the range of 1500–2000 °C led to the formation of predominantly single-phase (Hf, Zr, Ti, Ta, Mo)B2 or (Hf, Zr, Nb, Ta, Mo)B2 hexagonal structures characteristic of high entropy borides. Oxidation resistance for these borides was improved by as much as a factor of ten when compared to conventional commercial diborides. Vickers and nanoindentation hardness measurements show the indentation size effect and were found to be as much as 50% higher than that reported for the same high entropy boride configuration made by other methods, with average values reaching up to 38 GPa (for the highest Vickers load of 200 gf). Density functional theory calculations with a partial occupation method showed that (Hf, Zr, Ti, Ta, Mo)B2 has a higher hardness but a lower entropy forming ability compared to (Hf, Zr, Nb, Ta, Mo)B2, which agrees with the experiments. Overall, these results indicate the strong potential of using microwave-induced plasma as a novel approach for synthesizing high entropy borides.

Abstract
This study presents a numerical model of the hybrid-stabilized argon–steam thermal DC plasma torch of a new design for generating an argon–steam plasma suitable for efficient abatement of persistent perfluorinated compounds. The model includes the discharge region and the plasma jet flowing to the surrounding steam atmosphere contained in a plasma-chemical chamber. Compared to previous studies, the torch had a smaller nozzle diameter (5.3 mm) and a reduced input power (20–40 kW) and arc current (120–220 A). The outlet region for the plasma jet extends to 20 cm downstream of the exit nozzle. Fluid dynamic and thermal characteristics together with diffusion of argon, hydrogen and oxygen species, and distribution of plasma species in the discharge and the plasma jet are obtained for currents from 120 to 220 A. The results of the calculations show that the plasma jet exhibits high spatiotemporal fluctuations in the shear layer between the plasma jet and colder steam atmosphere. The most abundant species in the plasma jet are hydrogen and oxygen atoms near the jet center, and molecules of H2, O2 and OH in colder surrounding regions. Satisfactory agreement is obtained with measurements of the radial temperature and electron number density profiles near the jet center close to the nozzle exit.

Published: June 2022

Abstract
In this paper, a systematic design method for tunable metasurface based on liquid crystal (LC) is proposed, which exhibits the property of polarization selection. A compact LC-based meta-atom with a dimension of 0.12 λ × 0.12 λ is designed. The metasurface element consists of a pair of planar metallic structures, between which the LC is sandwiched. The equivalent circuit, electric field distribution, and current distribution elaborate on the design method and operating principle of the LC-based metasurface in detail. Full wave simulations show that the tunable metasurface provides bandpass and bandstop characteristics for TE and TM polarization, respectively. The center frequencies of the passband and stopband are tuned from 10.88 GHz to 10.3 GHz and 10.90 GHz to 10.18 GHz, and the tuning range reaches up to 5.5% and 6.8%, respectively. Compared with the existing work, tunability is introduced while maintaining the polarization selection characteristics. Moreover, frequency responses of the LC-based metasurface under various incident angles from 0° to 70° are kept to be stable for arbitrary LC states. In addition, a prototype sample is designed, fabricated, and measured to verify the proposed design method.
LO-mode phonon of KCl and NaCl at 300 K by inelastic x-ray scattering measurements and first principles calculations
Authors: Togo Atsushi , Hayashi Hiroyuki , Tadano Terumasa , Tsutsui Satoshi , Tanaka Isao 
Published: June 2022

Abstract
Longitudinal-optical (LO) mode phonon branches of KCl and NaCl were measured using inelastic x-ray scattering (IXS) at 300 K and calculated by the first-principles phonon calculation with the stochastic self-consistent harmonic approximation. Spectral shapes of the IXS measurements and calculated spectral functions agreed well. We analyzed the calculated spectral functions that provide higher resolutions of the spectra than the IXS measurements. Due to strong anharmonicity, the spectral functions of these phonon branches have several peaks and the LO modes along Γ–L paths are disconnected.
Deep subclass alignment transfer network based on time–frequency features for intelligent fault diagnosis of planetary gearboxes under time-varying speeds
Authors: Han Songjun , Feng Zhipeng 
Published: June 2022

Abstract
Vibration signals of planetary gearboxes have complex components and time-varying characteristics. As the unstable operation of planetary gearboxes leads to unbalanced data distribution within vibration signals, it is difficult to extract gearbox fault information hidden in a large amount of data. Therefore, fault diagnosis of planetary gearboxes under nonstationary conditions is highly challenging. For the past few years, intelligent diagnosis methods have been extensively studied in the fault diagnosis field. However, inappropriate signal representations, inadequate training samples, and data differences increase the difficulty of diagnosing planetary gearbox faults. To address the above issues, this paper proposes an intelligent diagnostic framework based on time–frequency features and a deep residual joint subclass alignment transfer network (DSATN) for planetary gearbox fault diagnosis under nonstationary conditions. One-dimensional vibration signals are converted into time–frequency representation through signal processing techniques to reflect the variation of vibration frequency components within the time–frequency domain with time. During network training, the DSATN evaluates the data distributions between relevant subclasses in source and target tasks by using the local maximum mean discrepancy. Also, it utilizes a nonlinear transformation to align the global data distributions between both tasks, thus improving the generalization of the trained model for small sample sets. The proposed method is validated through planetary gearbox experiments and achieves good fault classification in the time–frequency domain of nonstationary vibration signals. Different gear and planet bearing fault categories are successfully identified.

Abstract
The Gibbs energy ΔG
kp(τ, T) of kink pair formation on screw dislocations in bcc Nb has been determined as a function of shear stress τ at different temperatures T ⩽ 100 K using an accelerated molecular dynamics method and a bond-boost potential. From ΔG
kp(τ, T), the stress dependence of the entropy and the enthalpy of kink pair formation could be obtained using standard thermodynamic relations. The entropy of formation increases with increasing shear stress, following a phenomenologically predicted τ

Published: June 2022

Abstract
Gold nanorods (AuNRs) possess a high optical nonlinear coefficient, ultrafast optical response speed and widely tunable localized surface plasmon resonance (LSPR) wavelength covering the visible and near infrared region. Therefore, they are extensively investigated for many optical applications. However, the poor thermal stability of the AuNRs seriously restricts their practical performance. In addition, for many applications, such as optical communication or laser modulation, AuNRs have to be combined with transparent solids, for example polymers, glass or crystals to make devices. Here, we report on the preparation of 0.23 mg AuNR dispersed methyl silicone resin (MSR) with longitudinal LSPR (L-LSPR) wavelength (1450 nm) in the optical communication window. We found that AuNR-silicone composites possess high thermal stability. After calcination in ambient environment at a temperature of 250 °C for 10 h, the L-LSPR peak of the sample can remain longer than 1380 nm, implying that the NR shape of the Au particles was well maintained. Using the open-aperture Z-scan technique, the nonlinear absorption coefficient of the composites was measured as −11.71 cm GW−1, higher than many nonlinear materials. Thus, the thermally stable AuNR@SiO2-MSR composite with high nonlinearity is promising for practical applications in the optical communication window.

Published: June 2022

Abstract

Objective. In this work, a dedicated end-to-end deep convolutional neural network, named as Triple-CBCT, is proposed to demonstrate the feasibility of reconstructing three different material distribution volumes from the dual-energy CBCT projection data. Approach. In Triple-CBCT, the features of the sinogram and the CT image are independently extracted and cascaded via a customized domain transform network module. This Triple-CBCT network was trained by numerically synthesized dual-energy CBCT data, and was tested with experimental dual-energy CBCT data of the Iodine-CaCl2 solution and pig leg specimen scanned on an in-house benchtop system. Main results. Results show that the information stored in both the sinogram and CT image domains can be used together to improve the decomposition quality of multiple materials (water, iodine, CaCl2 or bone) from the dual-energy projections. In addition, both the numerical and experimental results demonstrate that the Triple-CBCT is able to generate high-fidelity dual-energy CBCT basis images. Significance. An innovative end-to-end network that joints the sinogram and CT image domain information is developed to facilitate high quality automatic decomposition from the dual-energy CBCT scans.
Li2O-ZnO-MoO3-SeO2 glass-nanocomposites and their crystalline counterparts: microstructure, electrical transport mechanism and first principle DFT analysis
Authors: Sengupta Aditi , Halder Prolay , Ali Mir Sahidul , Ghosh Chandan Kumar , Bhattacharya Sanjib 
Published: June 2022

Abstract
Li2O doped glass-nanocomposites and their crystalline counterparts have been developed. Micro-structural study reveals the distribution of Li2Zn2(MoO4)3, ZnMoO4, Zn(MoO2)2, Li2Mo6O7 and Li2MoO3 nanorods in the glass-nanocomposites. Crystalline counterparts of them exhibit enhancement in sizes of nanophases. DFT and Density of States (DOS) spectra may be considered here to confirm the conducting nature of these nanophases. The ionic conductivity is found to be a function of frequency as well as temperature. In the small value of frequency, flat-conductivity may arise owing to the diffusional motion of Li+ ions whereas the ‘higher frequency dispersion’ may cause the nature of the motion of lithium ions with a tendency of sub-diffusive random trapping. As the crystalline counterpart is formed by controlled heating, ZnSeO3 chain-structure is expected to break by increasing the length and breadth of molybdate rod-like structures, which may lead to the formation of more voids (defects), where Li+ ions are supposed to be trapped. 10%–13% of the net Li+ ions are contributing to electrical transport processes.

Abstract
We present the photometric analysis of six short-period systems (EI Oct, V336 TrA, NX Boo, V356 Boo, PS Boo, and V2282 Cyg). This is the first photometric analysis of these systems except for V336 TrA. Observations were conducted for 27 nights at three observatories in the northern and southern hemispheres. We calculated a new ephemeris for each of the systems using our minimum times and additional literature. The Markov Chain Monte Carlo (MCMC) approach was used to determine the eclipse timing variation trends of the systems. We found a likely orbital growth for V336 TrA and PS Boo; four other systems show a linear trend in orbital period changes, which is most likely due to the accumulation of measurement errors in their linear ephemeris parameters. The light curve analysis was performed using the Physics of Eclipsing Binaries (PHOEBE) 2.3.59 version code with the MCMC approach. The absolute parameters of the systems were calculated by using the Gaia Early Data Release 3 (EDR3) parallax. The positions of the systems were also depicted on the Hertzsprung–Russell (H-R) and

There is also a strong relationship between the mass ratio and the radius ratio in the W UMa systems for which we also provided a new relation. We compared the M–R updated relationships in this study with seven systems in other studies obtained using the spectroscopic method. In addition, we estimated some of the absolute parameters for 1734 EW systems, based on the new relationships.

Abstract
Efficiency of convolutional artificial neural networks in the problem of finding nonlinearity parameters proportional to the local and non-local cubic dielectric susceptibilities of a medium and intensity of the incident radiation, fully describing the self-focusing character of elliptically polarized laser beams, is demonstrated. It is shown that realization of the predictive algorithm by the neural network can be improved by using complex structured light so that the error is lowered down to percent units.
Systematic study of proton radioactivity half-lives based on the relationship between Skyrme-Hartree-Fock and the macroscopic quantities of nuclear matter*
Authors: Cheng Jun-Hao , Zhang Zhen , Wu Xi-Jun , Chu Peng-Cheng , Li Xiao-Hua 
Published: June 2022

Abstract
In this study, we systematically investigate the proton radioactivity half-lives of 33 spherical nuclei based on the relationship between Skyrme parameters and the macroscopic quantities of nuclear matter. Using the two-potential approach with the spherical Skyrme-Hartree-Fock model, the correlation between proton radioactivity half-life and the macroscopic quantities is analyzed. Moreover, we obtain a new Skyrme parameter set by fitting the two most weighted macroscopic quantities. Compared with the Skyrme parameters MSL0 and the theoretical model of proton radioactivity UDLP, the theoretical proton radioactivity half-life calculated using the new Skyrme parameter set can better reproduce the experimental data.
