Two‐stage partial image‐text clustering (TPIT‐C)
Authors: Guo Dongjin , Su Xiaoming , Lian Yahong , Liu Limin , Wang Haibo 
Published: June 2022

AbstractDeep multi‐model clustering is a challenging task for data analysis since it learns a universal semantic representation to find correct clusters from heterogeneous samples. However, most existing methods 1) lack an effective approach to getting a global representation of visual instances, which results in a huge semantic gap between visual and textual space. 2) hardly consider partial multi‐modal, where each instance is represented by only one modality. In reality, the pairing information for modalities is not available for all instances. To tackle the above issues, we propose a novel model called the Two‐Stage Partial Image‐Text Clustering (TPIT‐C) model. Firstly, we build an interpretable reasoning network to obtain the salient regions and semantic concepts of the scene in order to generate global semantic concepts. Secondly, we construct an adversarial learning module to align textual and visual instances into a unified space by virtue of cycle‐consistency. The experimental evaluations on public unpaired multi‐model datasets illustrated that the proposed method has better performance and the effectiveness of our algorithm in the partial image‐text clustering task.
Research on teaching effect of power electronics experiment simulating engineering application system
Authors: Zhao Guopeng 
Published: June 2022

AbstractTo enable students to establish the basic concept of engineering applications, this paper presents the experimental content simulating engineering application systems in the course of Power Electronics Experiment. Through the realization of each step of the experiment, students can complete the system level experiment closed to the engineering application. Taking the dc‐motor speed control system as an example, this paper allows students to realize a simple open‐loop speed control system, and answer questions related to practical engineering applications. Then, students apply the double‐closed‐loop speed control system simulating the engineering application to do the experiment, and answer questions again. By comparing the speed control performance of the motor, students can master how to control the dc‐motor accurately and stably. By comparing the correct rate of questions, it can be seen that the experiment simulating engineering application systems can obtain a higher correct rate of answering questions. The proposed teaching method makes students understand how to realize a stable and reliable engineering system, and establish a project concept of the power electronic application. Through the questionnaire survey of students, it can be obtained that the experiment simulating engineering application systems improves the experimental effect on understanding the composition and the working principle of the power electronic application systems.
A Novel and Practical Synthesis of Tryptanthrin
Authors: Feng Yisi , He Yong , Chen Shiyun , Gao Yonghao , Gui Shuangying 
Published: June 2022

AbstractTryptanthrin was synthesized through a two-step reaction of oxidation and condensation in a one-pot method, with isatin and sodium hypochlorite as starting materials. The influence of sodium hypochlorite, acetonitrile dosage, oxidation reaction temperature, and reaction time on the yield of the target product during the reaction was investigated. The following optimal reaction conditions were obtained: the ratio of n (isatin) to n (sodium hypochlorite) was 2:1, and the reaction time was 6–8 hours at room temperature. The structure of tryptanthrin was confirmed by matching the IR, NMR, and mass data with the literature report. The study shows that the chemical reaction route designed in this report is short, with high yield and purity of the target product. Its low production cost and simple operation method are expected to be applicable to industrial production.

AbstractObesity is an increasing health problem all over the world. In combination with the current COVID-19 pandemic, this has turned into a massive challenge as individuals with overweight and obesity at all ages show a significant increase in their risk of getting severe COVID-19. Around 20% of all patients that were hospitalized for COVID-19 suffered from obesity alone, whereas obesity in combination with other metabolic comorbidities, such as type 2 diabetes and hypertension, account for up to 60% of all hospitalizations in relation to COVID-19. Therefore, it is of immense importance to put the spotlight on the high incidence of obesity present already in childhood both by changing the individual minds and by encouraging politicians and the whole society to commence preventive interventions for achieving a better nutrition for all social classes all over the world. In the current review, we aim to explain the different pathways and mechanisms that are responsible for the increased risk of severe COVID-19 in people with overweight and obesity. Furthermore, we discuss how the pandemic has led to weight gains in many people during lockdown. At the end, we discuss the importance of preventing such an interface between a non-communicable disease like obesity and a communicable disease like COVID-19 in the future.

AbstractIntroduction In the future, clinical dental students, as health service providers, will play a key role in the oral care of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) patients. Clinical dental students need to increase their knowledge of HIV because it is vital for the diagnosis and management of HIV/AIDS patients that they have a positive attitude regarding oral care behavior toward HIV/AIDS patients. This study aims to explain the relationship between the knowledge, attitudes, and behavior of clinical dental students in the oral care of HIV/AIDS patients at Airlangga University Dental Hospital.Materials and Methods This study used a cross-sectional approach with a sample of 132 respondents. The sample was taken by purposive sampling technique. The independent variable in this study was the attitudes and behavior of clinical dental students toward the care of HIV/AIDS patients. The dependent variable in this study was the knowledge and attitudes of clinical dental students toward the oral care of HIV/AIDS patients. The research data obtained were analyzed using Spearman's rho at ≤0.05.Result There was significant correlation between knowledge and attitudes (p = 0.001, r = 0.596); knowledge and behavior (p = 0.001, r = 0.637); attitudes and behavior (p = 0.001, r = 0.699) of dentistry students in the care of HIV/AIDS patients oral cavity.Conclusion Clinical dental students' knowledge of HIV/AIDS will influence their attitudes toward HIV/AIDS patients and their behavior in the oral care of HIV/AIDS. It is hoped that future research can be conducted by adding other independent variables to determine a wider range of factors that affect oral care in HIV/AIDS patients.
Exploring the pedagogical use of the rating scale for functional adequacy in L1 writing instruction
Authors: Nuzzo Elena , Bove Giuseppe 
Published: June 2022

Abstract
This study aims to investigate whether a short training, during which a group of native Italian university students used the scale for Functional Adequacy (FA) developed by Kuiken and Vedder (2017) to assess texts written by their peers and their own texts, lead them to improve their L1 writing skills. The participants were assigned to an experimental (N = 15) and a control group (N = 15). A pre-test / treatment / post-test design was adopted. Results showed that the participants in the experimental condition benefited from the instructional treatment, but the gains they had in comparison to the control group were not statistically significant.
Holistic and analytic assessment of functional adequacy
Authors: Pallotti Gabriele 
Published: June 2022

AbstractThis study looks at the correlation between functional adequacy (FA), holistically assessed, and analytic linguistic measures, in a corpus of texts written by Italian monolingual and multilingual primary school pupils. Texts were first evaluated using the FA rating scales by Kuiken and Vedder (2017,2018), plus one for Coherence & Cohesion from the CEFR (Council of Europe, 2001′). They were then coded for a number of features directly bearing on FA and its subdimensions. Results show correlations between holistic scores and analytic measures, such as those between Content and the number of words or secondary idea units (r = .59 / .65). Others were less strong, yet going in the expected direction, e.g. more ambiguous referential expressions were negatively correlated to Comprehensibility. Correlations were generally stronger for monolingual than for multilingual children.

Published: June 2022

Abstract
The interfacial modification effect of the molybdenum trioxide (MoO3) buffer layer inserted between Al and black phosphorus (BP) was investigated with photoemission spectroscopy. The results show that MoO3 buffer layer can effectively prevent the destruction of the outermost BP lattice by Al thermal deposition and change the interface electronic structure between Al and BP. At the MoO3/BP interface, there is an interface dipole pointing from MoO3 to BP. During the metal deposition process, an interfacial chemical reaction between Al and MoO3 was found. These observations would provide insight for fabricating high-performance BP-based devices.
Designing doping strategy in arsenene monolayer for spintronic and optoelectronic applications: a case study of germanium and nitrogen as dopants
Authors: Van On Vo , Ha Chu Viet , Anh Dang Tuan , Guerrero-Sanchez J , Hoat D M 
Published: June 2022

Abstract
In this work, the structural, electronic, and magnetic properties of arsenene monolayer doped with germanium (Ge) and nitrogen (N) atoms are investigated using density functional theory calculations. Pristine monolayer is dynamically stable and it possesses a wide indirect band gap. Ge doping induces magnetic semiconductor (MS) nature generated by the semiconductor behavior in both spin channels with significant spin asymmetry around the Fermi level. The dopant produces mainly magnetic properties. Upon increasing the doping concentration, different doping configurations along armchair, zigzag edges, and hexagonal ring have been proposed. The MS nature is retained with an odd number of Ge atoms, meanwhile an eVen number leads to the disappearance of magnetism. In contrast, N doping induces a gap reduction of 11.80%, preserving the non-magnetic nature. At higher doping level, different electronic features including semiconductor, nearly semimetallic, and metallic natures are obtained depending on the doping concentration and configurations. In addition, the formation energy and cohesive energy are calculated to analyze the systems’ stability. Our results show that different doping arrangements induce novel features in arsenene monolayer for applications in spintronic and optoelectronic devices.

Abstract
We have conceived and built the HILITE (High-Intensity Laser-Ion Trap Experiment) Penning-trap setup for the production, confinement and preparation of pure ensembles of highly charged ions in a defined quantum state as a target for various high-intensity lasers. This enables a broad suite of laser-ion interaction studies at high photon energies and/or intensities, such as non-linear photo-ionisation studies. The setup has now been used to perform experiments at one such laser facility, namely the FLASH Free-Electron Laser at DESY in Hamburg, Germany. We describe the experimental possibilities of the apparatus, the results of the first measurements and future experiments at other laser facilities.
Light dynamics around an exceptional point in a 1D photonic bandgap waveguide
Authors: Dey Sibnath , Roy Arpan , Ghosh Somnath 
Published: June 2022

Abstract
Exceptional points (EP) in a system parameter space at which eigenvalues and corresponding eigenvectors coalesce are ubiquitous in non-Hermitian systems. Many unconventional applications have been proposed while encircling around the EPs. One of the unique application is the direction-dependent mode conversion. Here the appearance of an EP has been investigated in a planar 1D Bragg reflection waveguide(BRW) geometry, which has provided an additional degree of freedom to explore EP-based exotic light dynamics. A planar 1D BRW consists of periodic dielectric arrays and a defect dielectric layer forming the core. An inhomogeneous customized gain-loss profile is incorporated in the core region to couple two quasi-guided transverse electric (TE) modes so that the waveguide hosts an EP of order two. Here, we propose a dynamical EP encirclement scheme and corresponding asymmetric mode conversion phenomenon between two photonic bandgap quasi-guided TE modes in a 1D photonic bandgap-guided structure. Our findings will be potentially important to open up a fertile platform using the paradigm of non-Hermitian coupling to meet a wide range of exotic integrated chip-scale applications in the context of mode selectivity for switching and conversion.

Abstract
The 12C+12C fusion reaction was studied in the range of E
c.m.=8.9 to 21 MeV using the active-target Time Projection Chamber. With full information on all tracks of the reaction products, cross sections of the 12C(12C,8Be)16Og.s. channel and the 12C(12C,3α)12C channel could be measured down to the level of a few milibarns. The 12C(12C,8Be)16Og.s. reaction channel was determined to be 10

mb at E
c.m.=11.1 MeV, supporting the direct α transfer reaction mechanism. The 12C(12C,3α)12C reaction channel was studied for the first time using an exclusive measurement. Our result does not confirm the anomaly behavior reported in the previous inclusive measurement by Kolata et al. [Phys. Rev. C 21, 579 (1980)]. Our comparisons with statistical model calculations suggest that the 3α channel is dominated by the fusion evaporation process at E
c.m. > 19 MeV. The additional contribution of the 3α channel increases the fusion reaction cross section by 10% at energies above 20 MeV. We also find that an additional reaction mechanism is needed to explain the measured cross section at E
c.m. < 15 MeV at which point the statistical model prediction vanishes.

Solving the Quispel–Roberts–Thompson maps using Kajiwara–Noumi–Yamada’s representation of elliptic curves

Abstract
It is well known that the dynamical system determined by a Quispel–Roberts–Thompson map (a QRT map) preserves a pencil of biquadratic polynomial curves on

CP

CP

. In most cases this pencil is elliptic, i.e. its generic member is a smooth algebraic curve of genus one, and the system can be solved as a translation on the elliptic fiber to which the initial point belongs. However, this procedure is rather complicated to handle, especially in the normalization process. In this paper, for a given initial point on an invariant elliptic curve, we present a method to construct the solution directly in terms of the Weierstrass sigma function, using Kajiwara–Noumi–Yamada’s parametric representation of elliptic curves.
Criticality and network structure drive emergent oscillations in a stochastic whole-brain model
Authors: Barzon Giacomo , Nicoletti Giorgio , Mariani Benedetta , Formentin Marco , Suweis Samir 
Published: June 2022

Abstract
Understanding the relation between the structure of brain networks and their functions is a fundamental open question. Simple models of neural activity based on real anatomical networks have proven to be effective in describing features of whole-brain spontaneous activity when tuned at their critical point. In this work, we show that structural networks are indeed a crucial ingredient in the emergence of collective oscillations in a whole-brain stochastic model at criticality. We study analytically a stochastic Greenberg–Hastings cellular automaton in the mean-field limit, showing that it undergoes an abrupt phase transition with a bistable region. In particular, no global oscillations emerge in this limit. Then, we show that by introducing a network structure in the homeostatic normalization regime, the bistability may be disrupted, and the transition may become smooth. Concomitantly, through an interplay between network topology and weights, a large peak in the power spectrum appears around the transition point, signaling the emergence of collective oscillations. Hence, both the structure of brain networks and criticality are fundamental in driving the collective responses of whole-brain stochastic models.
