Theoretical tidal evolution constants for stellar models from the pre-main sequence to the white dwarf stage
Authors: Claret A. 
Published: April 2023

Aims. One of the most reliable means of studying the stellar interior is through the apsidal motion in double line eclipsing binary systems since these systems present errors in masses, radii, and effective temperatures of only a few per cent. On the other hand, the theoretical values of the apsidal motion to be compared with the observed values depend on the stellar masses of the components and more strongly on their radii (fifth power). The main objective of this work is to make available grids of evolutionary stellar models that, in addition to the traditional parameters (e.g. age, mass, log g, Teff), also contain the necessary parameters for the theoretical study of apsidal motion and tidal evolution. This information is useful for the study of the apsidal motion in eclipsing binaries and their tidal evolution, and can also be used for the same purpose in exoplanetary systems.
Methods. All models were computed using the MESA package. We consider core overshooting for models with masses ≥1.2M⊙. For the amount of core overshooting we adopted a recent relationship for mass × core overshooting. We adopted for the mixing-length parameter αMLT the value 1.84 (the solar-calibrated value). Mass loss was taken into account in two evolutionary phases. The models were followed from the pre-main sequence phase to the white dwarf (WD) stage.
Results. The evolutionary models containing age, luminosity, log g, and Teff, as well as the first three harmonics of the internal stellar structure (k2, k3, and k4), the radius of gyration βy, and the dimensionless variable α, related to gravitational potential energy, are presented in 69 tables covering three chemical compositions: [Fe/H] = −0.50, 0.00, and 0.50. Additional models with different input physics are available.

Authors: Riker Ulf 
Published: April 2023

ZusammenfassungIntegrative Medizin verbindet ärztliche Kompetenz in den Bereichen konventioneller und komplementärer Medizin auf rationaler Basis. Zu den komplementären Therapieverfahren zählt die Hufelandgesellschaft aus gutem Grund auch die Homöopathie: Sie ist dank hochwertiger Studien aus Grundlagen- und Versorgungsforschung nicht nur wissenschaftsbasiert, sondern auch versorgungsrelevant. Evidenzbasiert ist sie ohnehin, wenn man die Sackett’sche Definition zugrunde legt und neben der externen Evidenz aus Studien auch die interne Evidenz aus ärztlicher Erfahrung sowie die Präferenzen der Patientinnen und Patienten berücksichtigt. Der Beitrag zeigt dazu zwei Beispiele, wie die Homöopathie bei schulmedizinischer Therapieresistenz helfen kann.

Published: April 2023

Abstract
In the cm-wave range, the skin depth is comparable to the micron radius of ferromagnetic wires and thus their magnetic and conductive properties will influence the scattered electromagnetic field. Solving the scattering problem by considering the complicated internal magnetic structure of the wire becomes unpractical. There is thus a need to develop hybrid methods when the external problem of scattering on an inclusion is solved together with the experimental impedance conditions on its surface. Herein, we propose an accurate broadband impedance measurement technique operating up to

15

GHz. The printed circuit board measurement and calibration cells designed in this work allow flexibility in choosing external stimuli such as magnetic field, tensile stress, and heat. The experimental impedance can be then used as the boundary condition in electromagnetic simulations making it possible to model, predict and design wire-based composites using numerical solvers such as CST Studio Suite.

Abstract
Graphene and other two-dimensional materials (2DMs) have been shown to be promising candidates for the development of flexible and highly-sensitive strain sensors. However, the successful implementation of 2DMs in practical applications is slowed down by complex processing and still low sensitivity. Here, we report on a novel development of strain sensors based on Marangoni self-assemblies of graphene and of its hybrids with other 2DMs that can both withstand very large deformation and exhibit highly sensitive piezoresistive behaviour. By exploiting the Marangoni effect, reference films of self-assembled reduced graphene oxide (RGO) are first optimized, and the electromechanical behaviour has been assessed after deposition onto different elastomers demonstrating the potential of producing strain sensors suitable for different fields of application. Hybrid networks have been then prepared by adding hexagonal boron nitride (hBN) and fluorinated graphene (FGr) to the RGO dispersion. The hybrid integration of 2D materials is demonstrated to become a potential solution to increase substantially the sensitivity of the produced resistive strain sensors without compromising the mechanical integrity of the film. In fact, for large quasi-static deformations, a range of gauge factor values up to 2000 were demonstrated, while retaining a stable performance under cyclic deformations.
Modelling and dynamic analysis of a novel seven-dimensional Hamilton conservative hyperchaotic systems with wide range of parameter

Published: April 2023

Abstract
The study of chaotic attractors has been a hot issue in complex science research in recent years. However, most of the current research has focused on low-dimensional dissipative systems. High-dimensional conservative systems have both conservative and hyperchaotic properties, the phase space is integer dimensional and does not have attractors, and the trajectories expand in multiple directions, thus having higher complexity and spatial ergodicity. In addition, the high dimensional conservative system with wide parameter range not only has better dynamic characteristics, but also has a good application prospect in the field of information security. In this paper, a novel seven-dimensional Hamiltonian conservative hyperchaotic system (7D-HCHCS) is constructed. The dynamical properties of this system are described by analyzing the rate of change of phase space volume, phase trajectory diagram, Poincaré map, Lyapunov exponential spectrum (LEs), bifurcation diagram, equilibrium point, and system complexity. A new pseudo-random number generator (PRNG) is designed on this basis, and the key stream generated by this PRNG passes the NIST test. Besides, the phase diagrams and Poincaré map under a wide range of parameters are compared. The results show that the proposed system satisfies the Hamilton energy conservation and can generate hyperchaotic flow. It also has good pseudorandom characteristics, ergodicity under a large range of control parameters, which also has good prospects in the field of information security.

Published: April 2023

Abstract
This study introduces a Ge20Sb15Se65 chalcogenide-glass-based photonic crystal fiber (PCF) with high birefringence and nonlinearity and ultra-low confinement loss, in which two elliptical air holes are added in the core. The propagation properties of the proposed PCF are investigated in mid-infrared range (3.0–5.0 μm) using the finite element method (FEM). Simulation results indicate that optimizing structural parameters can increase the birefringence and nonlinear coefficient to a maximum of 3.16 × 10−1 and 5937 W−1km−1 (in y-polarization mode), respectively, a significantly low confinement loss reach 10−14 dB m−1 at 3.0 μm wavelength, there can obtain one zero dispersion wavelength in the study band, and the designed structure can be fabricated using available technology. The designed PCF will have promising application in mid-infrared fiber fields, optical communication, super-continuum generation, precision, and nonlinear optics.
A bio-inspired expandable soft suction gripper for minimal invasive surgery—an explorative design study
Authors: Kortman Vera G , Sakes Aimée , Endo Gen , Breedveld Paul 
Published: April 2023

Abstract
Gripping slippery and flexible tissues during minimal invasive surgery (MIS) is often challenging using a conventional tissue gripper. A force grip has to compensate for the low friction coefficient between the gripper’s jaws and the tissue surface. This study focuses on the development of a suction gripper. This device applies a pressure difference to grip the target tissue without the need to enclose it. Inspiration is taken from biological suction discs, as these are able to attach to a wide variety of substrates, varying from soft and slimy surfaces to rigid and rough rocks. Our bio-inspired suction gripper is divided into two main parts: (1) the suction chamber inside the handle where vacuum pressure is generated, and (2) the suction tip that attaches to the target tissue. The suction gripper fits through a

∅

10 mm trocar and unfolds in a larger suction surface when being extracted. The suction tip is structured in a layered manner. The tip integrates five functions in separate layers to allow for safe and effective tissue handling: (1) foldability, (2) air-tightness, (3) slideability, (4) friction magnification and (5) seal generation. The contact surface of the tip creates an air-tight seal with the tissue and enhances frictional support. The suction tip’s shape grip allows for the gripping of small tissue pieces and enhances its resistance against shear forces. The experiments illustrated that our suction gripper outperforms man-made suction discs, as well as currently described suction grippers in literature in terms of attachment force (

Published: April 2023

Abstract
Caloric cooling enlisting solid-state refrigerants is potentially a promising eco-friendly alternative to conventional cooling based on vapor compression. The most common refrigerant materials for elastocaloric cooling to date are Ni-Ti based superelastic shape memory alloys. Here, we have explored tuning the operation temperature range of Ni50.8Ti49.2 for elastocaloric cooling. In particular, we have studied the effect of thermal treatments (a.k.a. aging) on the transformation temperature, superelasticity, and elastocaloric effects of Ni50.8Ti49.2 shape memory alloy tubes. The isothermal compressive test revealed that the residual strain of thermally-treated Ni-Ti tubes at room temperature approaches zero as aging time is increased. Short-time aging treatment at 400 °C resulted in good superelasticity and elastocaloric cooling performance with a large tunable austenite finish (A
f) temperature range of 24.7 °C, as determined from the A
f temperature of the samples that were aged 5–120 min. The main reason of the property change is the formation of a different amount of Ni4Ti3 precipitates in the NiTi matrix. Our findings show that it is possible to tailor the A
f temperature range for development of cascade elastocaloric cooling systems by thermally treating a starting single composition Ni-Ti alloy.

Abstract

Goals/Purpose
Perioperative management of estradiol therapy varies considerably among plastic surgeons performing aesthetic surgeries. This study aimed to review available literature regarding perioperative management of estradiol therapy in aesthetic surgery patients, and the risk it poses for developing VTE in the perioperative period.

Methods/Technique
A literature search was performed using online databases to identify studies evaluating VTE in aesthetic surgery patients taking oral contraceptives (OCPs) or hormone replacement therapy (HRT), and transgender patients on feminizing hormone therapy undergoing non-flap feminization surgery (facial feminization and breast augmentation procedures). Reported outcomes were extracted from these studies and summarized.

Results/Complications
A systematic review of the literature yielded 225 studies. Five of these studies met inclusion criteria. One study that was excluded, referenced an article that met inclusion criteria, which was ultimately included in our review for a total of six studies, representing 3,635 patients.

Conclusion
Data regarding perioperative management of estrogen therapy is limited in the literature, and standardized guidelines for aesthetic surgery patients have not been elucidated. This has led to inconsistencies in how estrogen is managed for elective, cosmetic procedures. Further research is needed to determine standardized practice guidelines. In the meantime, case-by-case evaluation of surgical appropriateness should continue. Surgeons should also consider risk-mitigating strategies, such as a focus on patient education, more intentional patient questioning regarding estrogen-containing product use, a preoperative coagulability workup for patients with a personal or family history indicative of possible coagulopathy, and specialty-wide efforts to create an aesthetics database and evidence-based guidelines.
Ecological aspect of the larval parasitoid Diadegma hiraii (Hymenoptera: Ichneumonidae) as a potential biological control agent of soybean pod borer Leguminivora glycinivorella (Lepidoptera: Tortricidae)
Authors: Yoshimura Hideto , Tabuchi Ken , Konishi Kazuhiko 
Published: April 2023

Abstract
The larval parasitoid Diadegma hiraii (Kusigemati) was evaluated as a potential biological control agent of the soybean pod borer, Leguminivora glycinivorella (Matsumura). The timing of adult emergence after overwintering was ascertained, and land-use factors that enhance population density were analyzed. Host cocoons were collected and exposed to different temperatures and photoperiod regimes. Subsequently, the emergence of parasitoid was monitored. Land-use types were categorized into 4 land-use types (Poaceae, Fabaceae, Brassicaceae, and forest). Adult parasitoid emergence was dependent on temperature, but largely unaffected by photoperiod. The estimated emergence time of parasitoid was 3 months before the occurrence of the host, suggesting that the overwintered generation may lay eggs in alternate hosts. Parasitism rate was positively correlated with the area covered by Poaceae plants within a 500-m radius of the soybean field. Based on the results of the overwintering ecology and landscape analysis, D. hiraii probably completes its life cycle in the agroecosystems. The parasitoid’s effectiveness as a biological control agent may be influenced by the arrangement of land-use types in the agroecosystems surrounding soybean fields. However, the pest control provided by D. hiraii is limited because of approximately 30% of parasitism rate. Consequently, a combination of this species and cultural control and/or other biological control agents is suggested for sustainable soybean cultivation.

Published: April 2023

Abstract
Oxidative imbalances have been observed in various neurological diseases. Despite the microbiological control in cryptococcal meningitis (CM), a proportion of previously healthy patients experience a clinical deterioration known as post-infectious inflammatory response syndrome (PIIRS). However, the antioxidant status in PIIRS remains unclear. In this study, we found that the serum antioxidant status of HIV-negative immunocompetent CM patients during PIIRS episodes was lower than that of healthy controls. There was a relationship between baseline serum indirect bilirubin levels and the development of PIIRS, and serum uric acid levels may indicate the severity of the disease during PIIRS episodes. Oxidative stress may play a role in the development of PIIRS.
Two-temperature accretion flows around strongly magnetized stars and their spectral analysis

Published: April 2023

ABSTRACT
We investigate two-temperature accretion flows onto strongly magnetized compact stars. Matter is accreted in the form of an accretion disc upto the disc radius (rd), where, the magnetic pressure exceeds both the gas and ram pressure and thereafter the matter is channelled along the field lines onto the poles. We solve the equations of motion self-consistently along the field lines, incorporating radiative processes like bremsstrahlung, synchrotron, and inverse-comptonization. For a given set of constants of motion, the equations of motion do not produce unique transonic solution. Following the second law of thermodynamics, the solution with the highest entropy is selected and thereby eliminating the degeneracy in solution. We study the properties of these solutions and obtain corresponding spectra as a function of the magnetic field (B*), spin period (P) and accretion rate of the star ($\dot{M}$ ). A primary shock is always formed just near the surface. The enhanced radiative processes in this post-shock region slows down the matter and it finally settles on the surface of the star. This post-shock region contributes to ${\gtrsim}99.99~{{\ \rm per\ cent}}$ of the total luminosity obtained from the accretion flow. It is still important to study the full accretion flow because secondary shocks may be present for some combination of B*, P, and $\dot{M}$ in addition to primary shocks. We find that secondary shocks, if present, produce an extended emission at higher energies in the spectra.
On the determination of Galactic globular cluster metallicities from the periods and V-band amplitudes of their fundamental-mode RR Lyrae variables
Authors: Sarajedini Ata , Gokmen Sevinc 
Published: April 2023

ABSTRACT
There are primarily two relations currently being used in the literature to calculate the metal abundance of ab-type RR Lyrae variables from their periods andV-band amplitudes. They are the one from Alcock et al., which utilizes both the stars’ period and amplitude and the one from Sarajedini et al., which makes use of solely the stars’ period of modulation. In this work, we are seeking to test which of these relations is most accurate in reproducing the spectroscopic metal abundances of Galactic globular clusters containing ab-type RR Lyraes to which we can apply these relations. For our sample of 600 ab-type RR Lyrae variables in 33 Galactic globular clusters, we find very similar results for both equations as regards the accuracy of the mean metallicity calculated for each globular cluster as compared with spectroscopic abundance measurements for these clusters. This implies that knowledge of only the periods of ab-type RR Lyrae variables in a globular cluster is sufficient to allow a determination of the mean metallicity of that cluster. In particular, once corrected for the adopted metallicity scale, both of these equations are able to reproduce the spectroscopic metal abundance of each cluster with an accuracy of ±0.28 dex.
