Aims. We conducted a systematic investigation of the microlensing data collected during the previous observation seasons for the purpose of re-analyzing anomalous lensing events with no suggested plausible models.
Methods. We found that two anomalous lensing events, OGLE-2018-BLG-0584 and KMT-2018-BLG-2119, cannot be explained with the usual models based on either a binary-lens single-source (2L1S) or a single-lens binary-source (1L2S) interpretation. We tested the feasibility of explaining the light curves of the events with more sophisticated models by adding either an extra lens (3L1S model) or a source (2L2S model) component to the 2L1S lens system configuration.
Results. We find that a 2L2S interpretation explains the light curves of both events well and that for each event there are a pair of solutions resulting from the close and wide degeneracy. For the event OGLE-2018-BLG-0584, the source is a binary composed of two K-type stars and the lens is a binary composed of two M dwarfs. For KMT-2018-BLG-2119, the source is a binary composed of two dwarfs of G and K spectral types and the lens is a binary composed of a low-mass M dwarf and a brown dwarf.
Investigation of the post-05 adolescents’ families’ attitudes toward fertility——A case study of Changshu
Authors: Xie Junze 
Published: January 2023

Under the influence of social, economic, cultural, and other factors in the new era, young people, who are responsible for the country’s future, have different attitudes toward fertility from those of their predecessors. It is of great practical significance to study their attitudes toward fertility. Based on the analysis of the questionnaire survey on post-05 adolescents’ families in Changshu City, this paper indicates:

The family income has a certain degree of influence on the number of children, but there is no positive correlation;
post-05 adolescents are more inclined to have brothers or sisters who have the same biological genders as they do;
Compared with their parents, who have low reproduction willingness, adolescents’ reproductive willingness gradually increases.

Based on these conclusions, the following policy suggestions are put forward:

More opportunities should be created for practitioners to accompany their families.
Schools should avoid transmitting extreme gender normative education.
People should advocate the sustainability of adolescents’ positive attitudes toward childbearing under the inclusive and diverse concept of fertility.
Transcription Factor ELK3 Promotes Stemness and Oxaliplatin
Resistance of Glioma Cells by Regulating RNASEH2A
Authors: Mei Yimin , Chen Duoning , He Shike , Ye Jinping , Luo Ming , Wu Qiangjun , Huang Yuan 
Published: January 2023

AbstractOxaliplatin is a member of the platinum group that is often used to treat glioma,
a common type of malignant brain tumor, though it does not come with desirable
and notable effects. This study attempted to investigate how ELK3 impacts the
oxaliplatin resistance of glioma cells and its molecular mechanism.
Bioinformatics analysis was employed to screen mRNAs with differential
expression in glioma cells and predict the possible regulator downstream. We
used qRT-PCR to detect the expression of ELK3 and RNASEH2A. Dual-luciferase and
ChIP assays were adopted to reassure the regulatory relationship between the
two. We also evaluated cell viability and sphere formation efficiency through
CCK-8 and sphere formation assay and calculated the IC50 value by using CCK-8
assay. The expression of stemness-related proteins (ALDH1 and Nanog) was
assessed through western blot. Glioma cells and tissues presented a
significantly high expression of ELK3, the knock-down of which would reduce the
cell viability, stemness and oxaliplatin resistance dramatically. Bioinformatics
analysis predicted RNASEH2A to be the downstream regulator of ELK3. RNASEH2A was
remarkably upregulated in glioma tissue and cells. The results from dual
luciferase assay and ChIP experiment verified the binding relationship between
RNASEH2A promoter region and ELK3. Then through rescue experiments, we confirmed
that overexpression of RNASEH2A could compensate for the inhibition of glioma
cell progression resulting from the knock-down of ELK3. ELK3 could promote
stemness and oxaliplatin resistance of glioma cells by upregulating RNASEH2A,
indicating that targeting ELK3/RNASEH2A axis may be a possible solution
to overcome oxaliplatin resistance of glioma cells.
Rhyming prose and archaizing
Authors: El-Zawawy Amr M. 
Published: January 2023

Abstract
The present paper discusses the translation of the maqāmāt (i.e., assemblies) from Arabic into
English. The focus is on two main issues: the translation of rhyming prose into English and the problem of archaizing the language
when translating old literary texts, especially Arabic ones. The discussion of these two topics draws on different views,
especially Catford’s, Newmark’s, and Pym’s, and examples translated by the author and compared to Prendergast’s translation ([1915] 2015), the only rendition available. This discussion also touches upon the
dichotomy of foreignization versus domestication, as explicated by Venuti (1997). The paper concludes that translating expressive
texts is quite an undertaking, particularly if they are contingent on rhyming prose and archaisms as their basic features. Another
important conclusion is that the translator should keep an eye on the temporal distance between the two texts (i.e., the source
text and the target text). Archaisms are therefore proposed to sprinkle the translated text with that perceived aspect of time.
However, this does not mean that the target text will appear incomprehensible, for archaizing should be confined to the lexical
level and some syntactic constructions which characterize literary prose.

Abstract
Thermoluminescence (TL) response of γ-irradiated Cr3+ doped MgAl2O4 nanocrystals is studied to investigate the impact of dopant ions on intrinsic defects and trap distribution. At low doping concentration, the broad TL glow curve has a dominant incomplete peak attributed to deep F+ centers around 673 K and contribution from shallow

Electron spin resonance spectra show the interaction of electron spins at paramagnetic F+/V− centers with isolated and paired Cr3+ ions with increase in Cr doping concentration.

In this paper, we prove that the role of the velocity gradient tensor can be replaced by the combination of the diagonal part of the velocity gradient tensor and the non-diagonal part of the magnetic gradient tensor or by the combination of the diagonal part of the magnetic gradient tensor and the non-diagonal part of the velocity gradient tensor. The main interest among others is that the diagonal part of a gradient tensor is related to the deformation while the non-diagonal part is related to the rotation. Thus, our theorems may provide us with a new viewpoint to understand the potential singularity of the 3D MHD flow.
Oscillation period of the truncated simple pendulum
Authors: Torcal-Milla Francisco Jose 
Published: January 2023

Abstract
In this manuscript, a non typical kind of simple pendulum called Truncated Simple Pendulum is analysed to obtain its oscillation period, frequency, and angular frequency. It is easily derived that its motion can be viewed as the concatenation of two pendular movements with different lengths, contributing each one to half of the period of the complete oscillation. An analytical formulation is derived and corroborated with an experiment showing high agreement. This experiment could be interesting as a proposed exercise for the students or as a laboratory practical work. Besides, the gravity acceleration can be determined from each singular experiment and averaged to obtain it with lesser experimental error. In addition, it can be used to evaluate energy conservation theorem and small angle approximation (Law of isochronism) for the pendular oscillation. The level of the manuscript makes it appropriate for undergraduate students and introductory physics courses.
Teaching uniform linear motion using an Arduino sensor and a smartphone device
Authors: Karakotsou Christina , Zafiriadis Ilias 
Published: January 2023

Abstract
In this work, we designed and implemented an Arduino-based experiment to study one-dimensional uniform linear motion. The position of a small vehicle running at a constant velocity in one dimension, is measured using an ultrasonic sensor. A Bluetooth module connected to an Arduino board is paired with a smartphone, where data are acquired and position vs time curves of the vehicle are plotted on the smartphone’s screen. Students can share the experimental data via their smartphones and study uniform linear motion through guided experiments. The educational experience of the classroom implementation of the project is also presented. The results show that pairing an Arduino-based sensor with an android device, improves students’ comprehension of motion, enhances their motivation and cultivates positive attitude and anticipation for the forthcoming science lessons.
Everything can be magnetized: simulating diamagnetic and paramagnetic response of everyday materials in magnetic balance experiments
Authors: Laumann Daniel , Ries Matthias , Heusler Stefan 
Published: January 2023

Abstract
Magnetic properties are universal and inherent in all matter. While most experimental approaches focus on ferromagnetism and electromagnetism, few experiments exist to analyse diamagnetism and paramagnetism. To demonstrate these mostly unknown types of magnetic, magnetic balance experiments represent a simple and compelling approach. However, phenomenological experiments are not sufficient to develop a fundamental understanding of these types of magnetism. This paper presents an interactive simulation that can be used to complement magnetic balance experiments. It enables learners to understand diamagnetism and paramagnetism more deeply by incorporating interactive visual models gaining insights beyond the real experiments. Among other things, the simulation enables the analysis of substances without the possibility of detecting magnetic properties in real experiments, it visualizes the temporal evolution of magnetization and explains the influence of eddy currents.
Dynamic cone-beam CT reconstruction using spatial and temporal implicit neural representation learning (STINR)
Authors: Zhang You , Shao Hua-Chieh , Pan Tinsu , Mengke Tielige 
Published: January 2023

Abstract

Objective. Dynamic cone-beam CT (CBCT) imaging is highly desired in image-guided radiation therapy to provide volumetric images with high spatial and temporal resolutions to enable applications including tumor motion tracking/prediction and intra-delivery dose calculation/accumulation. However, dynamic CBCT reconstruction is a substantially challenging spatiotemporal inverse problem, due to the extremely limited projection sample available for each CBCT reconstruction (one projection for one CBCT volume). Approach. We developed a simultaneous spatial and temporal implicit neural representation (STINR) method for dynamic CBCT reconstruction. STINR mapped the unknown image and the evolution of its motion into spatial and temporal multi-layer perceptrons (MLPs), and iteratively optimized the neuron weightings of the MLPs via acquired projections to represent the dynamic CBCT series. In addition to the MLPs, we also introduced prior knowledge, in the form of principal component analysis (PCA)-based patient-specific motion models, to reduce the complexity of the temporal mapping to address the ill-conditioned dynamic CBCT reconstruction problem. We used the extended-cardiac-torso (XCAT) phantom and a patient 4D-CBCT dataset to simulate different lung motion scenarios to evaluate STINR. The scenarios contain motion variations including motion baseline shifts, motion amplitude/frequency variations, and motion non-periodicity. The XCAT scenarios also contain inter-scan anatomical variations including tumor shrinkage and tumor position change. Main results. STINR shows consistently higher image reconstruction and motion tracking accuracy than a traditional PCA-based method and a polynomial-fitting-based neural representation method. STINR tracks the lung target to an average center-of-mass error of 1–2 mm, with corresponding relative errors of reconstructed dynamic CBCTs around 10%. Significance. STINR offers a general framework allowing accurate dynamic CBCT reconstruction for image-guided radiotherapy. It is a one-shot learning method that does not rely on pre-training and is not susceptible to generalizability issues. It also allows natural super-resolution. It can be readily applied to other imaging modalities as well.
Postural and longitudinal variability in seismocardiographic signals
Authors: Azad Md Khurshidul , Gamage Peshala T , Dhar Rajkumar , Sandler Richard H , Mansy Hansen A 
Published: January 2023

Abstract

Objective. Low frequency cardiovascular vibrations detectable on the chest surface (termed seismocardiography or SCG) may be useful for non-invasive diagnosis and monitoring of various cardiovascular conditions. A potential limitation of using SCG for longitudinal patient monitoring is the existence of intra-subject variability, which can contribute to errors in calculating SCG features. Improved understanding of the contribution of intra-subject variability sources may lead to improved SCG utility. This study aims to quantify postural and longitudinal SCG variability in healthy resting subjects during normal breathing. Approach. SCG and ECG signals were longitudinally acquired in 19 healthy subjects at different postures (supine, 45° head up, and sitting) during five recording sessions over five months. SCG cycles were segmented using the ECG R wave. Unsupervised machine learning was used to reduce SCG variability due to respiration by grouping the SCG signals into two clusters with minimized intra-cluster waveform heterogeneity. Several SCG features were assessed at different postures and longitudinally. Main results. SCG waveform morphological variability was calculated within each cluster (intra-cluster) and between two clusters (inter-cluster) at each posture and data collection session. The variabilities were significantly different between the supine and sitting but not between supine and 45° postures. For the 45° and sitting postures, the intra-cluster variability was not significantly different, while the inter-cluster variability difference was significant. The energy ratio between different frequency bands to total spectral energy in 0.5–50 Hz were calculated and were comparable for all postures. The combined cardiac timing intervals from the two clusters showed significant variation with postural changes. There was significant heart rate difference between the clusters and between postural positions. The SCG features were compared between longitudinal sessions and all features were not significantly different, Significance. Several SCG features significantly varied with posture suggesting that posture needs to be specified when comparing SCG changes over time. Longitudinally comparable SCG feature values suggests that significant longitudinal differences, if observed, may reflect true alternations in the cardiac functioning over time.

Published: January 2023

Abstract
In this work, a very fast integrated transport model involving every region that interacts directly with the plasma of a tokamak, has been developed. The confined region is modeled in 1.5D, while the scrape-off layer has a 0D structure. For the core region, a physics-based analytical regression based on a set of simulations with the transport model TGLF [Staebler 2005 Phys. Plasmas
12 102508] has been produced. For the H-mode regime, an average edge-localized-modes model is applied in the pedestal region. In the scrape-off layer a two-point model for electron temperature (exhaust) and a particle balance for the species density at the separatrix have been implemented. All the models have first been validated individually in a standalone setting. Finally, six fully integrated simulations of an L-mode discharge, and five H-mode discharges, have been performed in the Fenix flight simulator [Janky et al 2019 Fusion Eng. Des.
146 1926, Fable et al 2022 Plasma Phys. Control. Fusion
64 044002], including transients, matching the experimental trajectories of an ASDEX upgrade discharge during flat-top and ramp-down. A broader validation including more discharges and the ramp-up phase is planned for the near future.
Enhanced electrical stability of thin film transistors based on nanocrystalline silicon films
Authors: Xu Hongyuan , Wan Guangmiao , Mai Jiaying , Jiang Zhixiong , Liu Bin , Zhang Shengdong 
Published: January 2023

Abstract
In this work, nanocrystalline silicon (nc-Si) films were achieved by using normally processing method of amorphous silica thin film transistors (a-Si TFTs), plasma enhanced chemical vapor deposition (PECVD). The effects of PECVD process parameters on the crystallization rate of nc-Si films were comprehensively studied and then an optimized nc-Si film has been achieved with a crystallinity of 50.87%. The electrical properties and stability of nc-Si TFTs are further investigated and compared with a-Si TFTs. The ΔV
th of the nc-Si TFTs are 0.14 V and −3.32 V under positive bias-temperature-illumination stress (60 °C, 30 V, 6000 nit) and negative bias-temperature-illumination stress (60 °C, −30 V, 6000 nit) after 1 h, which are 1.96 V and −5.51 V for a-Si TFT, respectively. The result reveals better photo stability of nc-Si TFTs than a-Si TFTs which is attributed to fewer defect states in nc-Si films.
Strain relaxation of semiconductor membranes: insights from finite element modeling
Authors: Mooney P M 
Published: January 2023

Abstract
Finite element (FE) models were employed to better understand the process used to fabricate elastically strain-relaxed in-place bonded semiconductor membranes for application as engineered substrates for semiconductor devices (Cohen et al 2005 Appl. Phys. Lett.
86 251902; Owen et al 2008 ECS Trans.
16 271; Owen et al 2009 Sci. Technol.

29 075009; Salehzadeh et al 2014 Semicond. Sci. Technol.
29 085002). Initial structures consist of a compressively strained, square semiconductor membrane atop a sacrificial layer that is subsequently removed by etching in an hydrofluoric acid (HF) solution. Elastic relaxation of the compressive strain bends the free area of the membrane toward the substrate. But for the dimensions of most of the structures employed in the fabrication of in-place bonded membranes, the bending by elastic strain relaxation alone is not sufficient for the membrane corners to contact the substrate. FE models, therefore, confirm that an attractive force between the surface of the membrane and the surface of the substrate in the HF solution must act to hold the membrane in place during the wet etching process. FE models also confirm that in the etch solution the interface between the membrane and the substrate must be a sliding interface in order for the membrane to lie flat on the substrate once the sacrificial layer has been completely removed.
Passive topological waveguide controlled by the boundary of the patterned area of external magnetic field with the hybrid quantum Hall and valley Hall effects
Authors: Fang Yun-tuan , Gong Ping , He Sailing 
Published: January 2023

Abstract
Topological waveguides with arbitrary pathway are desirable for many applications. In this paper we construct a triangular compound lattice consisting of magnetic dielectric rods. By breaking the space symmetry and the time-reversal symmetry, the structure generates topological edge states (TESs) from the hybrid quantum Hall effects and valley Hall effects. This topological edge waveguide pathway can be arbitrary arranged just by the external magnetic field. The hybrid topological phase provides a new and ultraflexible way to the reconfiguration of the TESs.
