Published: June 2023

ZusammenfassungMomordica charantia L. (Cucurbitaceae), allgemein bekannt als Bittergurke oder Bittermelone, weist eine lange Geschichte in der Behandlung von Diabetes und dessen Komplikationen auf. Über ihre antidiabetische Wirkung und ihre positive Wirkung auf den Blutzucker und die Lipidkonzentration wurde in zahlreichen In-vitro- und In-vivo-Studien berichtet, die für die beobachteten Auswirkungen verantwortlichen Substanzen sind indes noch nicht hinreichend beschrieben. In den letzten Jahren konzentrierte sich die Forschung immer mehr auf die besonderen Triterpenoide vom Cucurbitan-Typ, die in den Früchten und anderen Teilen der Pflanze reichlich vorhanden sind. Die vorliegende Arbeit fasst die antidiabetische Wirkung der sogenannten Momordicoside zusammen und erörtert ihre Verwendung in kommerziellen Präparaten.

Published: June 2023

AbstractThe occurrence of ovarian cyst in the neonate is rare and antenatally diagnosed by ultrasonography. This study aims to increase awareness about its occurrence and histological features. We performed a retrospective review on 10 cases of neonatal ovarian cyst (NOC) during 4 years (2016–2020) in a tertiary care center in South India. The neonates were diagnosed with abdominal cysts by the antenatal ultrasonogram in the third trimester. They were operated from day 5 to 35 days of age. There was no side predilection, and most of them were unilateral (9 out of 10 cases). Histopathological examination showed simple cysts (50%), serous cystadenomas (20%), cyst with no viable lining (20%), and follicular cyst (10%) and 90% of the cysts had torsion-induced changes. The pathologist and the clinician should be aware of the occurrence of serous histology in NOC cases.

Abstract
Aims and Objectives Gynecological neoplasms are among the most common cancers in female population of India and worldwide. Various new advances have been made to diagnose gynecological pathologies which include imprint cytology and frozen sections in addition to the histopathological techniques. The aim of the study was to assess the diagnostic accuracy of intraoperative diagnostic procedure with gold standard histopathology.
Method The study included 50 patients who had suspected gynecological neoplasm in a time period of 12 months. Their intraoperative diagnosis was made on frozen section and imprint cytology to rule out benign or malignant lesions and compared with gold standard histopathology.
Results Our study concludes that maximum cases of female genital tract neoplasms belonged to the age group of 19 to 76 years, with 60% cases in postmenopausal age group. Overall diagnosis of 62, 52, and 76% malignancies were made on imprint cytology, frozen section, and histopathological examination, respectively.
Conclusion The study concludes that diagnostic accuracy by intraoperative imprint cytology is higher (80%) than frozen section (76%). True positive cases were maximally reported by histopathology. True negative and false positive cases were equally reported by both frozen and imprint cytology. False negative cases were reported by frozen section more than by imprint cytology. The kappa statistical value was lesser in frozen versus histopathology and more in imprint versus histopathology. The sensitivity, specificity, positive predictive value, and negative predictive value for imprint cytology were 77.5, 90.0, 96.9, and 50%, respectively, whereas for frozen section, it was 72.5, 90.0, 96.7, and 45.0%, respectively.

Context Breeding for early maturity and higher yield is the principal objective in genetic improvement of Indian soybean. Yellow Mosaic Disease caused by Mungbean Yellow Mosaic India Virus (MYMIV) causes 80% yield loss in soybean. Aims This study aimed to develop early maturing, MYMIV resistant and high yielding soybean genotypes for enhancing soybean production and expanding the land area under cropping. Methods MYMIV resistance was introgressed from G. soja in to a widely adaptable cultivar JS 335 through a series of four generations of backcrosses and by evaluating derived progeny against MYMIV at a disease hot spot. Key results An extra-early maturing (71 days) genetic stock called NRC 252 was developed, which can be a potential gene donor in breeding for early maturing soybean varieties. Introgression lines YMV 1, YMV 2, YMV 11 and YMV 16 with MYMIV resistance and higher yield performance over recurrent parent and other check varieties were identified and characterised. Biplot analysis, assessing the main effect of genotype and the interaction of genotype with environment, revealed an ideal genotype with respect to 100-seed weight and grain yield that was also promising under sugarcane-soybean intercropping system in spring season. Conclusions Alleles from wild type soybean could improve yield attributing traits and MYMIV resistance in cultivated soybean. Improved genotypes such as YMV 1, YMV 2, YMV 11 and YMV 16 were found superior to the recurrent parent JS 335 as well as other check varieties. Implications The genotypes developed in the present study will help in reducing the damage caused by MYMIV disease and expansion of the area of soybean cultivation through intercropping with sugarcane.
Impact of global text cohesion on students’ listening comprehension of informational listening texts
Authors: Schmitz Anke , Brandt Hanne , Rothstein Björn 
Published: June 2023

Abstract
Listening comprehension serves as a basic means for communication and participation in society. Unfortunately,
especially low-performing students have difficulties understanding informational content presented in a listening format, even
more so than with the comprehension of printed texts. Based on empirical findings that text features, such as global text
cohesion, have proven to be effective for promoting reading comprehension, and cognitive processes of reading and listening to
academic texts share commonalities, the question arises as to how much global cohesion can support students’ listening
comprehension. 140 ninth-grade students in German secondary schools listened to one of two informational listening texts which
differed in their degree of global text cohesion (low vs. high in cohesion). Listening comprehension was assessed with a written
test after listening. Regression analyses show that global text cohesion promotes listening comprehension and that the effect of
cohesion remains significant and stable when controlling for topic-related prior knowledge and language-related background
variables. Low-performing students profited more from the highly cohesive text than high-performing students. Thus, cohesion
contributes to the comprehensibility of informational listening texts which can have implications for the construction of
listening texts and listening comprehension instruction at school.

Published: June 2023

Abstract
This article deepens the understanding of characteristic features of Shared Reading (SR) that can shed light on
health benefits of this literary practice suggested by previous research. We provide a detailed analysis of language, interaction,
reading strategies and collaborative meaning-making in an online SR group in which participants read and discussed a modernist
poem. We triangulate our analysis with results from a focus group with the participants. Our study is informed by psychological
theories about joint attention and its effects on social cohesion, mentalisation and perspective-taking. The analysis shows how
the SR format provides a space in which ingroupness, intersubjectivity, and perspective-taking are created and realised in
language use and interaction. Furthermore, our study suggests that many characteristic features of SR identified in earlier
research can still be observed in an online SR group. The study lays the ground for more conclusive research of the benefits of
this reading practice.

An observer in uniform circular motion experiences a similar effective temperature, operationally defined in terms of excitation and de-excitation rates, and physically interpretable in terms of synchrotron radiation, but this effective temperature depends not just on the acceleration but also on the orbital speed and the excitation energy. In this paper we consider an observer in uniform circular motion when the Minkowski vacuum is replaced by an ambient thermal bath, and we address the interplay of ambient temperature, Doppler effect, acceleration, and excitation energy. Specifically, we consider a massless scalar field in

spacetime dimensions, probed by an Unruh–DeWitt detector, in a Minkowski (rather than proper) time formulation: this setting describes proposed analogue spacetime systems in which the effect may become experimentally testable, and in which an ambient temperature will necessarily be present. We establish analytic results for the observer’s effective temperature in several asymptotic regions of the parameter space and provide numerical results in the interpolating regions, finding that an acceleration effect can be identified even when the Doppler effect dominates the overall magnitude of the response. We also identify parameter regimes where the observer sees a temperature lower than the ambient temperature, experiencing a cooling Unruh effect.
An inner product for 4D quantum gravity and the Chern–Simons–Kodama state
Authors: Alexander Stephon , Herczeg Gabriel , Freidel Laurent 
Published: June 2023

Abstract
We demonstrate that reality conditions for the Ashtekar connection imply a non-trivial measure for the inner product of gravitational states in the polarization where the Ashtekar connection is diagonal, and we express the measure as the determinant of a certain first-order differential operator. This result opens the possibility to perform a non-perturbative analysis of the quantum gravity scalar product. In this polarization, the Chern–Simons–Kodama state, which solves the constraints of quantum gravity for a certain factor ordering, and which has de Sitter space as a semiclassical limit, is perturbatively non-normalizable with respect to the naïve inner product. Our work reopens the question of whether this state might be normalizable when the correct non-perturbative inner product and choice of integration contour are taken into account. As a first step, we perform a semi-classical treatment of the measure by evaluating it on the round three-sphere, viewed as a closed spatial slice of de Sitter. The result is a simple, albeit divergent, infinite product that might serve as a regulator for a more complete treatment of the problem. Additionally, our results suggest deep connections between the problem of computing the norm of the CSK state in quantum gravity and computing the Chern–Simons partition function for a complex group.

Abstract
To improve the vibration isolation performance, a conventional passive two-parameter vibration isolator (VI) usually adopts the method of adding constant damping for energy dissipation. A compromise is made between the suppression of resonance peak and the rapid attenuation of transmissibility in the high-frequency band. A four-parameter-VI with frequency-dependent damping is a potential solution for this problem. The theoretical models of system transmissibility and equivalent damping are established by a normalization method, and the vibration isolation performance is compared with that of the two-parameter-VI and the three-parameter-VI. A novel four-parameter-VI with damping generated by a giant electrorheological fluid (GERF) damper is designed. The mechanical properties of the GERF damper are tested, and its damping effect is evaluated using an equivalent linearization method. Then, the vibration isolation performance of the four-parameter-VI is tested. The results show that: the vibration isolation performance of the four-parameter-VI can be affected by the damping ratio and the mass ratio. The four-parameter-VI exhibits the frequency-dependent damping characteristic of large damping in the low-frequency band and small damping in the high-frequency band by appropriately setting parameters. The vibration isolation ratio of the four-parameter-VI to white noise reaches 91.1% in the time domain with appropriate parameters, and the peak of the power spectral density curves decreases from 1.2 × 10−3 g2 Hz−1 to 0.16 × 10−3 g2 Hz−1 with a reduction of 1.04 × 10−3 g2 Hz−1 .
Low frequency twisted waves in a self-gravitating nonextensive complex plasma
Authors: Bukhari S , Bukhari Asad , Shahid M , Hussain A 
Published: June 2023

Abstract
The effects of dust–dust self-gravitational force and nonextensive characteristics of plasma species on the low frequency twisted waves owing to the helical wave structure in complex (dusty) plasmas are analyzed. The electrons and ions of the plasma are modelled by nonextensive q-distribution function while massive dust particles are Maxwellian distributed. The self-gravitational effects are incorporated in the Vlasov equation of kinetic theory where perturbed distribution function, electrostatic and gravitational potentials are expressed with Laguerre–Gauss functions. The governing equations of kinetic theory are solved together under paraxial approximations. The dispersion relations and damping rates of twisted dust-acoustic waves (TDAWs) are obtained for two situations; (a) super-extensivity (q < 1) and (b) sub-extensivity (q > 1). The effects of self-gravity, nonextensivity and twist parameter significantly modified the basic features of dust-acoustic waves. This study contributes to our understanding of the complex dynamics of TDAWs in interstellar dust clouds, considering the interplay of self-gravity, nonextensivity, and helical phase structures. The obtained theoretical and numerical results provide valuable insights into the behavior of these waves and offer a foundation for further investigations in this field. However, understanding of the topic can be enhanced through a combination of theoretical models, numerical simulations and observational data.
Tailoring spin-sensitive focusings by optical metasurfaces
Authors: Zhu Hongyuan , He Canhui , Zhang Runxuan , Song Zhengyong 
Published: June 2023

Abstract
Metalens is composed of artificially subwavelength metal or dielectric meta-atoms arranged according to phase distribution of lens, and it can focus wave in a compact and flexible manner. However, conventional geometric phase-based metalens cannot focus spin-sensitive splitting beams, hindering the simultaneous control of two spins. Here, spin-sensitive plasmonic metasurfaces are presented with independent phase modulation capability for circularly polarized channels. These metasurfaces encode phase information by integrating propagating phase and geometric phase to achieve arbitrarily independent control of focal length and focal position for circularly polarized waves (CPWs). Three metasurfaces, including longitudinally splitting focusing, multidimensional spin-sensitive splitting focusing, and multifocal metasurface, are numerically displayed to confirm these predictions. Firstly, a longitudinally splitting focusing is designed with focal length 3 μm under left-handed circular polarization (LCP) incidence and focal length 5 μm under right-handed circular polarization (RCP) incidence. Secondly, two anomalously reflected converging beams are formed by superimposing different gradient phases on a multidimensional spin-sensitive splitting focusing under LCP and RCP illuminations. Finally, a multifocal metasurface is presented, and it has bifocal points and four focal points under LCP and RCP incidences. This work provides novel methods for flexible control of circular polarization-sensitive focusing.
Topological phase transitions and Majorana zero modes induced by the periodic potential in an antiferromagnetic chain
Authors: Shen K W , Chen Q 
Published: June 2023

Abstract
We investigate the topological properties of an antiferromagnetic (AFM) chain with an on-site periodic potential, considering the intrinsic spin–orbit coupling and an external Zeeman field along with the nanowire. Our results indicate that Majorana zero modes (MZMs) can be observed by adjusting the strength of the periodic potential. We have calculated the energy spectrum, the wave-function and transport properties, and all these results support the existence of MZMs in the AFM chain. Additionally, multiple topological phase transitions occur as the strength of the periodic potential changes, and several regions support MZMs.

Abstract
This study aimed to investigate the tribological and microstructural characteristics of LM26 composites reinforced with silicon carbide to evaluate their suitability for high-temperature applications. For the sample fabrication, the modified stir-casting method was optimized using a Taguchi L16 orthogonal array. The wear rate and friction behavior were evaluated using the Taguchi’s S/N ratio analysis. When SiC was incorporated into the composite, the wear resistance increased by up to 15 wt%. The wear resistance of the LM26/SiC composite was improved compared to that of the pure LM26 aluminum alloy. The results of this study provide useful information to improve the wettability of metal matrix composites made from commercial-grade LM26 aluminum alloy by adjusting the SiC weight percentage. This type of composite has the potential as a replacement material for traditional applications such as heat sinks, heat exchanger fins, and electronic packaging.

AbstractPurpose. To study the impact on dose coverage and the dose to the healthy tissue applying optimized margins in single isocenter multiple brain metastases radiosurgery (SIMM-SRS) in linac machine based on setup rotations/translations induced errors calculated by a genetic algorithm (GA).Method.The following quality indices of SIMM-SRS were analyzed for 32 plans (256 lesions): Paddick conformity index (PCI), gradient index (GI), maximum (Dmax) and mean (Dmean) doses, local and global V12for the healthy brain. A GA based on Python packages were used to determine the maximum shift produced by induced errors of 0.2°/0.2 mm, and 0.5°/0.5 mm in 6 degrees of freedom.Results.In terms of Dmax, and Dmean, the quality of the optimized-margin plans remains unchanged (p > 0.072) concerning the original plan. However, considering the 0.5°/0.5 mm plans, PCI and GI decreased for ≥10 metastases, and local, and global V12increased considerably in all cases. To consider 0.2°/0.2 mm plans, PCI and GI get worse but local, and global V12improved in all cases.Conclusion.GA facilities to find the individualized margins automatically among the number of possible permutations of the setup order. The user-dependent margins are avoided. This computational approach takes into account more SRS sources of uncertainty, enabling the protection of the healthy brain by ‘smartly’ reducing the margins, and maintaining clinically acceptable target volumes’ coverage in most cases.
Measuring exciton-phonon coupling in semiconductor nanocrystals

Published: June 2023

Abstract
At low excitation density, the dynamics of excitons in semiconductor nanocrystals are largely dictated by their interactions with the underlying atomic lattice. This exciton-phonon coupling (EPC) is responsible, for example, for absorption and luminescence linewidths at elevated temperatures, relaxation processes following optical excitation, and even degradation of quantum coherent applications. Characterizing and understanding EPC is therefore central to guiding rational design of colloidal nanocrystal materials and their device applications. In this review, we compare different spectroscopic methods of measuring exciton-phonon interactions and the complementary information that they provide. We emphasize the development of a new technique, termed multidimensional coherent spectroscopy, that circumvents many of the limitations of traditional methods.
Estimating the electric vehicle charging demand of multi-unit dwelling residents in the United States
Authors: Cheng Xi , Kontou Eleftheria 
Published: June 2023

Abstract
Early battery electric vehicle (EV) adopters can access home chargers for reliable charging. As the EV market grows, residents of multi-unit dwellings (MUDs) may face barriers in owning EVs and charging them without garage or parking availability. To investigate the mechanisms that can bridge existing disparities in home charging and station deployment, we characterized the travel behavior of MUD residents and estimated their EV residential charging demand. This study classifies the travel patterns of MUD residents by fusing trip diary data from the National Household Travel Survey and housing features from the American Housing Survey. A hierarchical agglomerative clustering method was used to cluster apartment complex residents’ travel profiles, considering attributes such as dwell time, daily vehicle miles traveled (VMT), income, and their residences’ US census division. We propose a charging decision model to determine the charging station placement demand in MUDs and the charging energy volume expected to be consumed, assuming that MUD drivers universally operate EVs in urban communities. Numerical experiments were conducted to gain insight into the charging demand of MUD residents in the US. We found that charging availability is indispensable for households that set out to meet 80% state of charge by the end of the day. When maintaining a 20% comfortable state of charge the entire day, the higher the VMT are, the greater the share of charging demand and the greater the energy use in MUD chargers. The upper-income group requires a greater share of MUD charging and greater daily kWh charged because of more VMT.
