A review on recent advances in fabricating freestanding single-crystalline complex-oxide membranes and its applications
Authors: Ji Jongho , Park Sangwoo , Do Hagjai , Kum Hyun S 
Published: April 2023

Abstract
Complex-oxide materials are gaining a tremendous amount of interest in the semiconductor materials and device community as they hold many useful intrinsic physical properties such as ferro/piezoelectricity, pyroelectricity, ferromagnetism, as well as magnetostriction and other properties suitable for energy storage elements. Complex-oxides can also be complemented with conventional semiconductor-based devices or used by themselves to realize state-of-the-art electronic/photonic/quantum information devices. However, because complex-oxide materials have vastly different crystalline structures and lattice constant difference compared to conventional semiconductor devices (such as Si or III-V/III-N materials), integration of complex-oxides onto conventional semiconductor platforms has been difficult. Thus, there has been constant efforts to produce freestanding single-crystalline complex-oxide thin films such that these films can be transferred and integrated together with device platforms based on other materials. This review will provide a comprehensive review on single-crystalline complex-oxide membranes technology developed thus far: how they are synthesized, methods to release them from the substrate, and their outstanding properties and applications.
General N-soliton solutions to the two types of nonlocal Gerdjikov-Ivanov equations via Riemann-Hilbert problem
Authors: Yang Yingmin , Xia Tiecheng , Liu Tongshuai 
Published: April 2023

Abstract
This paper mainly makes use of the Riemann-Hilbert approach to solve the two types of nonlocal Gerdjikov-Ivanov equations derived by different nonlocal group reductions. The Riemann-Hilbert problem of the general Gerdjikov-Ivanov equation is constructed and the relations between the Riemann-Hilbert problems of the nonlocal Gerdjikov-Ivanov equations and the above Riemann-Hilbert problem are discussed in two parts. The general N-soliton solutions of the nonlocal Gerdjikov-Ivanov equations are acquired by solving the Riemann-Hilbert problems of the nonlocal equations under the reflectionless case and the matrix forms of the soliton solutions are given. In particular, the dynamics of the solutions are explored and the images of the general one-soliton solutions and two-soliton solutions of two types of nonlocal Gerdjikov-Ivanov equations are shown with the appropriate parameters.
TL defect center analysis and radiation shielding phenomenon In Ho3+: Pb(YB)2O7 composite glasses
Authors: Ashok Kallagadda , Francis E Daniel , Guntu Ravi Kumar 
Published: April 2023

Abstract
The aim of the ongoing research was to create resources that are mechanically durable, thermally luminous, and radiation-shielding. In this manner, we intended to synthesize lead borate glasses containing functional groups for yttrium and holmium. Ho2O3 doped glasses, which are typically used for luminescent purposes, will also be used to investigate the thermoluminescence characteristics under gamma radiation. XRD, SEM, EDX, and DTA techniques are used to examine the samples’ structure, chemical analysis, and thermal characteristics. To assess the samples’ micro-hardness, the test sample’s ultrasonic velocities are measured. The mass attenuation coefficient and order of radiation protection ability are shown by the radiation shielding characteristics of samples. It should be highlighted that Holmium ions alone are responsible for the variations in the shielding behavior of glasses. The TL characteristics of the samples were examined at gamma irradiation doses of 0, 10, and 25 kGy. Irradiation increases the TL Intensities that have been observed. The findings show that Ho2O3 is the only factor contributing to the TL phenomenon, and test samples exhibit substantial TL activity. Additionally, samples were examined using the DTA technique for changes in thermal stability. This also implies that changes in thermal stability are solely dependent on holmium concentration. Overall, the results showed that YPBH glasses are effective TL materials and strong radiation shielding resources with low thickness values.

Authors: Devi Elangbam Chitra , Singh Shougaijam Dorendrajit 
Published: April 2023

Abstract
Ni–Zn ferrite of compositional formula Ni0.5Zn0.5Fe2O4 was prepared by co-precipitation method. The effect of heat treatment at 600 °C, 800 °C, 1000 °C and 1200 °C on their structures and hence magnetic properties were investigated. Their phase analysis and morphological studies was done using XRD, FTIR, FT-Raman and SEM-EDAX. Room temperature magnetization loops of the prepared materials were recorded up to a maximum applied field of 15 kOe to study the effect of structural variation on magnetic properties. Further, magnetization loops of Ni–Zn ferrite heated at 1200 °C were recorded at 150 K and 50 K to investigate the variation of magnetic properties at low temperatures. Law of approach to saturation magnetization was applied to all the magnetization curves under investigation. The fitted parameters reveal information on the processes of magnetization, anisotropy constant, and saturation magnetization of Ni–Zn ferrites. Law of approach to saturation magnetization in the form M = M

s
(1− b/H

Published: April 2023

Abstract
Doping in metal oxide systems is being chased by many researchers since it is enhancing their properties. In the present study, Cu1-xMgxO nanoparticles, capped with EDTA were synthesized by the chemical co-precipitation method, with x = 0.000, 0.005, 0.010, 0.015, and 0.020, and further characterized by different techniques. The impact of doping by Mg2+ ions on the structural, optical, and magnetic properties of CuO nanoparticles was investigated and the antibacterial activity of the synthesized nanoparticles was studied by antibiofilm screening. The x-ray Powder Diffraction (XRD) patterns show the formation of a pure CuO phase with a good incorporation of Mg-dopant into the CuO lattice due to the comparable ionic radii of Cu2+ and Mg2+ ions. The Mg-dopant increases the crystallite size from 25 nm (at x = 0.000) to 28.12 nm (at x = 0.020). The Transmission Electron Microscope (TEM) images reveal the effect of Mg-doping on the morphology of CuO nanoparticles by decreasing their agglomeration, resulting in more uniform spherical-shaped nanoparticles. Energy Dispersive x-ray (EDX) and x-ray Photoelectron Spectroscopy (XPS) confirm the purity and the successful development of Mg-doped CuO nanoparticles. The changes in the characteristic vibrational modes of CuO are studied by Raman spectra, upon Mg-doping. Furthermore, the optical properties explored by Ultraviolet-Visible (UV–vis) spectroscopy reveal a redshift of the absorption peaks of CuO nanoparticles due to the Mg-doping. The energy gap (Eg) is affected by Mg-doping, where its broadening is attributed to the quantum confinement effect in CuO. The magnetic properties were investigated by Vibrating Sample Magnetometer (VSM) at room temperature. Cu1-xMgxO nanoparticles have combined paramagnetic and weak ferromagnetic behaviors. Besides, Cu1-xMgxO nanoparticles exhibited significant antibiofilm effects. These results highlight the potential use of Mg-doped CuO nanoparticles as antibiofilm agents.
Stability of hairy black holes in shift-symmetric scalar-tensor theories via the effective field theory approach
Authors: Khoury Justin , Noumi Toshifumi , Trodden Mark , Wong Sam S.C. 
Published: April 2023

Abstract
Shift-symmetric Horndeski theories admit an interesting class of Schwarzschild-de Sitter black hole solutions exhibiting time-dependent scalar hair. The properties of these solutions may be studied via a bottom-up effective field theory (EFT) based on the background symmetries. This is in part possible by making use of a convenient coordinate choice — Lemaître-type coordinates — in which the profile of the Horndeski scalar field is linear in the relevant time coordinate. We construct this EFT, and use it to understand the stability of hairy black holes in shift-symmetric Horndeski theories, providing a set of constraints that the otherwise-free functions appearing in the Horndeski Lagrangian must satisfy in order to admit stable black hole solutions. The EFT is analyzed in the decoupling limit to understand potential sources of instability. We also perform a complete analysis of the EFT with odd-parity linear perturbations around general spherically symmetric space-time.
Probing virtual ALPs by precision phase measurements: time-varying magnetic field background
Authors: Sharifian Mohammad , Zarei Moslem , Abdi Mehdi , Peloso Marco , Matarrese Sabino 
Published: April 2023

Abstract
We propose an experimental scheme for detecting the effects of off-shell axion-like particles (ALPs) through optical cavities. In this proposed experiment, linearly polarized photons are pumped into an optical cavity where an external time-dependent magnetic field is present. The magnetic field mediates an interaction between the cavity photons and ALPs giving rise to a modification in the phase of the cavity photons. The time-dependent nature of the external magnetic field prompts a novel amplification effect which significantly enhances this phase modification. A detection scheme is then proposed to identify such axion-induced phase shifts. We find that the phase modification is considerably sensitive to the photon-ALPs coupling constants gaγγ

Optical fiber vibration sensor for bearing fault detection based on Sagnac interferometer
Authors: Yang Xu , Li XianGuo , Meng DeJun , Shi Jia , Miao ChangYun 
Published: April 2023

Abstract
Bearings are crucial components in mechanical equipment, and bearing failure is one of the reasons for mechanical equipment safety accidents. In this work, an optical fiber vibration sensor based on Sagnac interferometer (SI) is proposed and applied to bearing fault detection. The polarization-maintaining fiber (PMF) is spliced between two single-mode fibers (SMFs) to form a SMF-PMF-SMF (SPS) fiber structure, which is connected with a 3 dB coupler to form a SI based on SPS fiber structure. The mass block is fixed in the middle of the PMF. When the monitored surface or structure vibrates, the stress of PMF will change and the Sagnac interference spectrum will be shifted, so that the vibration can be measured. The fabrication technology of sensor based on 3D printing is studied, and the structural parameters of the sensor are optimized through experiments and theoretical analysis. A vibration detection system and a rolling bearing vibration test platform based on SI and fiber ring laser are built. The experimental results show that the relative error between the experimental and theoretical results of healthy and faulty bearings is less than 1.60%, and the fault detection of bearings is realized. Temperature cross-sensitivity and stability of the sensing system are analyzed. The sensor has the advantages of simple structure, easy fabrication, anti-interference, etc, and has wide application prospects in engineering, machinery, security and other fields.

Authors: Qi Lin-Jing , Zhang Dong-Meng , Luo Song , He Biao , Wu Xi-Jun , Chen Xun , Li Xiao-Hua 
Published: April 2023

Abstract
In this study, derived from Balasubramaniam's formula [Phys. Rev. C 70, 017301 (2004)] and further considering the effect of the parent nucleus mass, blocking effect, and effect of reduced mass on cluster radioactivity half-lives, we propose a new Geiger-Nuttall law that is model-independent to systematically evaluate the half-lives of this process for 16 even-even nuclei and 10 odd-A nuclei. For comparison, a single universal curve for cluster radioactivity and α decay proposed by Poenaru [Phys. Rev. C 83, 014601 (2011)], a scaling law proposed by Horoi [J. Phys. G: Nucl. Part. Phys. 30, 945 (2004)], an extension of the Viola-Seaborg formula from α decay to cluster radioactivity proposed by Ren et al. [Phys. Rev. C 70, 034304 (2004)], a new semi-empirical formula for exotic cluster decay proposed by Balasubramaniam et al. [Phys. Rev. C 70, 017301 (2004)], and a unified formula for the half-lives of α decay and cluster radioactivity proposed by Ni et al. [Phys. Rev. C 78, 044310 (2008)] are also used. The calculated results of our new Geiger-Nuttall law are in good agreement with the experimental half-lives, with the least rms being 0.606, and are better than the compared values. Moreover, we extend this formula to predict the cluster radioactivity half-lives of 51 nuclei whose decay energies are energetically allowed or observed but not yet quantified in NUBASE2020.

Published: April 2023

Abstract
Silicon nanomaterials have been of immense interest in the last few decades due to their remarkable optoelectronic responses, elemental abundance, and higher biocompatibility. Two-dimensional silicon is one of the new allotropes of silicon and has many compelling properties such as quantum-confined photoluminescence, high charge carrier mobilities, anisotropic electronic and magnetic response, and non-linear optical properties. This review summarizes the recent advances in the synthesis of two-dimensional silicon nanomaterials with a range of structures (silicene, silicane, and multilayered silicon), surface ligand engineering, and corresponding optoelectronic applications.
A family of flexible two-dimensional semiconductors: MgMX2Y6 (M = Ti/Zr/Hf; X = Si/Ge; Y = S/Se/Te)
Authors: Yuan Junhui , Xue Kanhao , Miao Xiangshui , Ye Lei 
Published: April 2023

Abstract
Inspired by the recently predicted 2D MX2Y6 (M = metal element; X = Si/Ge/Sn; Y = S/Se/Te), we explore the possible applications of alkaline earth metal (using magnesium as example) in this family based on the idea of element replacement and valence electron balance. Herein, we report a new family of 2D quaternary compounds, namely MgMX2Y6 (M = Ti/Zr/Hf; X = Si/Ge; Y = S/Se/Te) monolayers, with superior kinetic, thermodynamic and mechanical stability. In addition, our results indicate that MgMX2Y6 monolayers are all indirect band gap semiconductors with band gap values ranging from 0.870 to 2.500 eV. Moreover, the band edges and optical properties of 2D MgMX2Y6 are suitable for constructing multifunctional optoelectronic devices. Furthermore, for comparison, the mechanical, electronic and optical properties of In2X2Y6 monolayers have been discussed in detail. The success of introducing Mg into the 2D MX2Y6 family indicates that more potential materials, such as Ca- and Sr-based 2D MX2Y6 monolayers, may be discovered in the future. Therefore, this work not only broadens the existing family of 2D semiconductors, but it also provides beneficial results for the future.
Entanglement witness and multipartite quantum state discrimination
Authors: Ha Donghoon , Kim Jeong San 
Published: April 2023

Abstract
We consider multipartite quantum state discrimination and show that the minimum-error discrimination by separable measurements is closely related to the concept of entanglement witness (EW). Based on the properties of EW, we establish some necessary and/or sufficient conditions on minimum-error discrimination by separable measurements. We also provide some conditions on the upper bound of the maximum success probability over all possible separable measurements. Our results are illustrated by examples of multidimensional multipartite quantum states. Finally, we provide a systematic way in terms of the EW to construct multipartite quantum state ensembles showing nonlocality in state discrimination.
Characteristics of 1D ordered arrays of optical centers in solid-state photonics
Authors: Kling Trevor , Hosseini Mahdi 
Published: April 2023

Abstract
Collective interaction of emitter arrays has lately attracted significant attention due to its role in controlling directionality of radiation, spontaneous emission and coherence. We focus on light interactions with engineered arrays of solid-state emitters in photonic resonators. We theoretically study light interaction with an array of emitters or optical centers embedded inside a microring resonator and discuss its application in the context of solid-state photonic systems. We discuss how such arrays can be experimentally realized and how the inhomogeneous broadening of mesoscopic atomic arrays can be leveraged to study broadband collective excitations in the array.
Probabilistic behavioral distance and tuning—reducing and aggregating complex systems
Authors: Hellmann Frank , Zolotarevskaia Ekaterina , Kurths Jürgen , Raisch Jörg 
Published: April 2023

Abstract
Given two dynamical systems, we quantify how similar they are with respect to their interaction with the outside world. We focus on the case where simpler systems act as a specification for a more complex one. Combining a behavioral and probabilistic perspective we define several useful notions of the distance of a system to a specification. We show that these distances can be used to tune a complex system. We demonstrate that our approach can successfully make non-linear networked systems behave like much smaller networks, allowing us to aggregate large sub-networks into one or two effective nodes. Finally, we discuss similarities and differences between our approach and

We are inspired by works in the

-critical NLS. In the seminal work of Bourgain and Wang (1997), they constructed such pseudoconformal blow-up solutions. Merle, Raphaël, and Szeftel (2013) showed an instability of Bourgain-Wang solutions. Although CSS shares many features with NLS, there are essential differences and obstacles over NLS. Firstly, the soliton profile to CSS shows a slow polynomial decay

. This causes many technical issues for small

. Secondly, due to the nonlocal nonlinearities, there are strong long-range interactions even between functions in far different scales. This leads to a nontrivial correction of our blow-up ansatz. Lastly, the instability mechanism of CSS is completely different from that of NLS. Here, the phase rotation is the main source of the instability. On the other hand, the self-dual structure of CSS is our sponsor to overcome these obstacles. We exploited the self-duality in many places such as the linearization, spectral properties, and construction of modified profiles.
HPV Cotesting of Unsatisfactory Papanicolaou Tests: Implications for Follow-up Intervals
Authors: Chen Fei , Hsu Lin Lawrence , Hindi Issa , Sun Wei , Shafizadeh Negin , Szeto Oliver , Brandler Tamar C , Simsir Aylin 
Published: April 2023

Abstract

Objectives
The 2019 American Society of Colposcopy and Cervical Pathology management guidelines recommend that patients with an unsatisfactory Papanicolaou (Pap) test (UPT) and negative human papillomavirus (HPV) cotest undergo repeat age-based screening in 2 to 4 months. The rationale is that a negative HPV test in the setting of an UPT may reflect an inadequate sample and therefore should not be interpreted as truly “negative.” For patients 25 years and older who are cotested, if HPV is positive for the 16 or 18 genotypes, direct referral for colposcopy is recommended. Our study aimed to determine if a negative HPV cotest result is predictive of the absence of a high-grade squamous intraepithelial lesion (HSIL) and whether these patients may be called back for repeat testing at an interval longer than 2 to 4 months.

Methods
Follow-up cervical cytology and biopsy results in women with UPT and HPV cotests from January 2017 to December 2021 were collected. Original UPT and HPV cotest results were correlated with the follow-up Pap and biopsy results.

Results
There were 1,496 (2.28%) UPT cases out of 65,641 total Pap tests. Among the 1,496 UPT cases, 1,010 (67.5%) had HPV cotesting; 676 (45.1%) were followed by repeat Pap or biopsy within 4 months and 850 (56.8%) within 12 months. The total follow-up rate was 81%, with a range of 3 days to 36 months. The HSIL rate in HPV-positive cases was 5.7% (3/53) vs 0.4% (2/539) (P = .006) in HPV-negative cases. In UPT, HPV cotesting showed negative predictive values for low-grade and high-grade squamous intraepithelial lesion detection of 98.5% and 99.6%, respectively, while positive predictive values were 19% and 5.7%.

Conclusions
A negative HPV cotest in individuals with UPT predicted the lack of HSIL in our study. Compliance with the recommended follow-up time of 2 to 4 months for women with UPT was low (45.1%). Our study suggests that women with UPT and negative HPV cotest may be safely called back at an interval longer than 4 months.
