Analysis of Mobile Phone Dependence among Students in Higher Vocational Institutions
Authors: Yang Yuqi
Published: October 2022

Students’ motivation for using mobile phones is mainly entertainment, followed by a sense of achievement and finally social interaction. Mobile phone dependency is a real problem for students in higher vocational institutions and accounts for up to 90% of the population. Students’ mobile phone dependence is influenced by their motivation to use, and the result is that the individual is physically and mentally impaired, which has some negative impact on their social functioning. In tests of students’ mobile phone dependence, the results are out of control > avoidance > wariness > inefficiency. Three ways of intervention are recommended: by actively guiding students in the scientific use of mobile phones, by strengthening control over classroom order management and by establishing a harmonious teacher-student connection through mobile phones.

Published: October 2022

With the development of multi-polarization in the world, the UN Security Council plays an increasingly important role in maintaining international peace and promoting international cooperation, which has attracted much attention from the academic and industrial circles. However, the current structure of five permanent and ten non-permanent members of the Council does not maximize efficiency and legitimacy, making it more difficult to resolve international conflicts on time. This article first has carried on the extensive search for relevant theories and finishing, and on this basis, using the survey method, literature research, interdisciplinary research method, qualitative analysis method, and other research methods. The goal is to balance the efficiency and the legitimacy of the UNSC, especially improving the council’s legitimacy. This paper draws the following conclusions: 1. Increase the number of seats on the Council by twenty-four (five permanent members, eight four-year renewable seats, and 11 non-permanent members) 2. It is impossible to abolish the veto completely, but permanent members should be urged to reduce the use of the veto through legislation. Given the political conflicts of interest and the complexity of revising the UN Charter, governments of all countries should promote internal negotiations as soon as possible, conduct in-depth dialogue and consultation on core major issues, clarify the principles and methods of reform, and determine practical solutions.

Research on the Cause and Coping Strategy of Implicit Aggression Among Female Students
Authors: Wu Ruiyan
Published: October 2022

Implicit aggression is a kind of indirect aggression in the conflict between the two, which occurs more among female than male. The aggression form is more secret. When students are in school, they interact more frequently, which is prone to conflicts and leads to implicit aggression. The purpose of this paper is to study the relationship among female students, learn the real examples of implicit aggression through interviews, and analyze the cause of implicit aggression among female students as well as the way they deal with it. It is found that the occurring of implicit aggression among female students and the way they deal with it have noting to do with one’s status in a relationship but is more related to one’s background and living environments. Therefore, to solve this problem, changes should be made by female students’ parents, teachers, as well as themselves.

Exposure of PM2.5 Exacerbates COVID-19 In Vivo
Authors: Wang Andrew Pindi
Published: October 2022

Coronavirus disease (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) affects many tissues and organs, especially lung damage. The respiratory system related comorbidities can increase the COVID-19 clinical symptoms and cause more damages. Since high PM2.5 exposure decreases the respiratory system function, I hypothesize that PM2.5 can induce aggravated COVID-19 symptoms. I propose to construct the human angiotensin converting enzyme 2 (hACE2) knock in mice model to mimic COVID-19 patients. PM2.5 particulates will be delivered into the mice container in the aerosol form for consecutive 5 days ending on day -7 (Day 0 is the day of SARS-CoV-2 virus challenge). On day 21, we will sacrifice the mice and analyze the autopsy samples via ELISA, flow cytometry and histology assays and so forth, which determine the secretion level of inflammatory cytokines and characterize the function of related tissue or organs. It will be shown that pre-PM2.5 exposure induces more severe COVID-19 symptoms with highly activated inflammatory responses.

Authors: Wei Xinyi
Published: October 2022

As a new media form and a new way of information transmission, short video represented by Douyin has become an important carrier for the audience to use fragmented time for social and entertainment consumption. The short video circle is continuously subdivided, extending a large number of vertical contents, and food is one of the subdivision fields of the short video category. As the most image of food bloggers, female food bloggers account for a lot, and its image construction has become the main factor attracting attention. This research is based on the image construction of female food bloggers on the Douyin platform, explores the image characteristics of women food bloggers in the current short video industry, and studies the relationship between the reasons behind them and the social background, expanding the in-depth research on the topic of “food bloggers” programs. This paper is based on Goffman’s “Dramaturgical Theory”, and its theoretical framework comes from the “media user experience model” proposed by Chinese scholar Yu. It uses the content analysis method to construct the category and analyze the content of the sample video. It is found that although the Douyin platform provides a free and personalized space for the voice of the female group, the self-awareness of the female group continues to awaken. However, the appearance characteristics of female food bloggers image created in the current Douyin platform reflect the “pseudo personalized” online celebrity production under commercial capital. In the online social networking platform, women’s consumption is still the mainstream, and the task of awakening women’s consciousness and pursuing gender equality is still arduous.

Exploring the impact of extrinsic motivation on users’ intention to continue using a gamified tourism commerce platform
Authors: Zang Zhanhe
Published: October 2022

Gamification has obtained increasing attention in a number of fields including management, marketing, education, and health care. In the tourism context, the users of online tourism services are fond of online application platforms that are enjoyable and interesting, where gamification can be applied. Besides, with the increasing types and amount of online tourism platforms, the user churn rate is very high. Therefore, it is crucial for online tourism platforms to keep the tourists from switching to other platforms and explore users’ motivations for using the platform. However, there are relatively few studies concerning the effects of the extrinsic motivation of gamification on users’ psychological needs for using online tourism platforms in detail. Based on self-determination theory and gamification literature, this research identifies four different types of extrinsic motivations and investigates their effects on users’ willingness to continue using gamified online travel platforms. Based on the questionnaire data, this research found that: 1) the four extrinsic motivations positively influence the satisfaction of consumers’ basic psychological needs, but have weaker impacts on competence needs; 2) the satisfaction of consumers’ three basic psychological needs is positively related to their intention to consistently use gamified travel platforms.

On the Application of Documentary Evidence Order System in Cases Involving E-commerce Platforms
Authors: Zhu Zimu
Published: October 2022

In 2020 the Supreme People’s Court of China issued new regulations on civil litigation. The regulations formalised a relatively well-developed system for the documentary evidence order system. This Article discusses the use of the system in tort and contract cases involving e-commerce platforms, dividing such cases into two categories: those where the platform is the direct counterparty and those where the third party is. This research is based on a large body of relevant academic literature and judicial cases, and leads to legislative proposals for further improvement of the order. It also proposes the idea of integrating and improving the system with the investigation order system, in view of the fact that the system cannot cover the situation where the evidence is under the control of a third party. In addition, the Article further compares the Chinese system of discovery orders with the common law systems of discovery, explains the reasons why the exchange of evidence system derived from discovery is not taken seriously in China, and proposes solutions.

The economics of marriage: Evidence from China
Authors: Gao Zhitong , Pang Jihong , Zhou Hongyong
Published: October 2022

Marriage market imbalances are common in modern society for social and economic reasons, including the increased cost of marriage caused by high housing prices and an imbalance in the number of men and women. We draw on the family economic theory of Gary Becker to study the general equilibrium of the marriage market in China. On the one hand, we find that the increasing price of houses, an important measure of marriage cost, has significantly reduced the marriage rate in China. Another determining factor that has reduced the marriage rate is an imbalance in the sex ratio, with more men than women, as a result of China’s one-child policy. On the other hand, higher GDP and educational levels have positive effects on the marriage rate. Interestingly, the rise in housing prices after the implementation of the two-child policy in China has had a more negative impact on the marriage rate. Overall, our findings have important policy implications for government.
Cooperative evolution with opinion formation in a complex social environment
Authors: Luo Yun , Li Yuke , Cheng Chun
Published: October 2022

Cooperation is a significant aspect in the daily activities of human or animal populations that involves the process of agents making decisions based in part on the ideas or beliefs of cooperators. The importance of communication in the evolutionary game cannot be overstated. In this paper, we offer a co-evolutionary game model on a communication network, including expressed and private opinions. Then, we present our theoretical analysis of scenarios characterized by different parameters, elucidating the relationship between the agents’ opinion formation process and the decision-making process. Finally, we run simulations with our proposed model. Surprisingly, we discover that whereas communication does not increase cooperation on Erdös–Rényi random networks, it does so on the Barabási–Albert scale-free network. Meanwhile, we discover that in the simulation results, the average of private opinions (simplified as values within [0,1]) changes in the same direction of the percentage of cooperators. Furthermore, we discover that deceivers who conceal their true private opinions may, to some extent, foster the formation of collaboration in the human population, which goes against our common sense.
Existence of vortices for Schrödinger equations with logarithmic and saturable nonlinearity
Authors: Chen Shouxin , Su Guange
Published: October 2022

In this paper, we study the existence of stationary vortex wave solutions of two kinds of nonlinear Schrödinger equations. For the first one, which is equipped with logarithmic nonlinearity arising from Bose–Einstein condensation, we consider two types of boundary value problems. In both cases, we establish the existence of positive solutions through a direct minimization method. For the second one, with a saturable nonlinearity originating from geometric optics, we use a constrained minimization approach to establish the existence of vortex wave solutions. Moreover, some explicit estimates for the bound of the wave propagation constant are derived.
Melnikov-type method for a class of planar hybrid piecewise-smooth systems with impulsive effect and noise excitation: Heteroclinic orbits
Authors: Wei Zhouchao , Li Yuxi , Moroz Irene , Zhang Wei
Published: October 2022

The classical Melnikov method for heteroclinic orbits is extended theoretically to a class of hybrid piecewise-smooth systems with impulsive effect and noise excitation. We assume that the unperturbed system is a piecewise Hamiltonian system with a pair of heteroclinic orbits. The heteroclinic orbit transversally jumps across the first switching manifold by an impulsive effect and crosses the second switching manifold continuously. In effect, the trajectory of the corresponding perturbed system crosses the second switching manifold by applying the reset map describing the impact rule instantaneously. The random Melnikov process of such systems is then derived by measuring the distance of perturbed stable and unstable manifolds, and the criteria for the onset of chaos with or without noise excitation is established. In this derivation process, we overcome the difficulty that the derivation method of the corresponding homoclinic case cannot be directly used due to the difference between the symmetry of the homoclinic orbit and the asymmetry of the heteroclinic orbit. Finally, we investigate the complicated dynamics of a particular piecewise-smooth system with and without noise excitation under the reset maps, impulsive effect, and non-autonomous periodic and damping perturbations by this new extended method and numerical simulations. The numerical results verify the correctness of the theoretical results and demonstrate that this extended method is simple and effective for studying the dynamics of such systems.
A method for extracting sole mechanical properties of Bragg reflector by GHz ultrasonic pulse-echo technique
Authors: Yanagitani Takahiko , Ishii Naoki , Kondo Keita , Suzuki Motoshi
Published: October 2022

Solidly mounted resonators (SMRs) with an acoustic Bragg reflector should be more suitable for high power RF filters than a self-standing structure because heat can be transferred to the supporting substrate. Thus, even though the demand for SMRs is expected to increase, the evaluation of the properties of the Bragg reflector that comprise them cannot be separated from the properties of the resonator as a whole. A method to evaluate the mechanical reflection coefficient of the Bragg reflector alone before the piezoelectric layer is grown would, therefore, be attractive, as it would be useful in optimizing the Bragg reflector. In this study, a nondestructive evaluation method of the reflector using a GHz ultrasonic pulse-echo technique is proposed. The Sc0.40Al0.60N film ultrasonic transducers with electromechanical coupling coefficient kt2 of 15.8% and longitudinal wave insertion loss of 7.0 dB with 77% fractional bandwidth were employed for the measurement system. Mo/SiO2 Bragg reflector test samples with various number of pairs were evaluated. The experimental mechanical reflectance of the Bragg reflector agreed well with theoretical results simulated by a mechanical equivalent circuit model.
Strong coupling for bifunctionality in organic systems
Authors: Benoit J. M. , Chevrier K. , Symonds C. , Bellessa J.
Published: October 2022

In this paper, we exploit the strong light–matter coupling to hybridize two materials for bifunctionality properties. The strong coupling has been achieved between a surface plasmon and two organic emitters: a J-aggregate cyanine dye, known for its high absorption and emission properties and a photochromic material in which absorption can be optically switched on and off. The optical properties are drastically modified between the activated and deactivated forms of the photochromic material coupled to the cyanine dye. In particular, the emission of the structure can be energy shifted by several hundreds of meV providing a way to build a tunable emission system. This system also reveals its potential for modifying the fluorescence of photochromes thanks to light–matter interaction instead of functionalization using covalent bonding.
Triad resonance of flexural gravity waves in a two-layer fluid within the framework of blocking dynamics
Authors: Bisht N. , Boral S. , Sahoo T. , Meylan Michael. H.
Published: October 2022

The present study deals with the formation of triads in flexural gravity waves in a two-layer density stratified fluid having a flexible plate-covered surface and an interface within the framework of blocking, which can be used as a mechanism for understanding the spectral distribution of wave energy. The physical model is considered in a two-dimensional Cartesian coordinate system, and the formations of triads are discussed geometrically and validated analytically. The study demonstrates the formation of at most eight triads of three different classes for flexural gravity waves before the threshold of blocking, whereas a maximum of six triads of three different classes have been reported in the case of free-surface gravity waves. However, at least twenty triads are formed for any frequency within the blocking limits for the compressive force lying within the threshold of blocking and buckling limit, irrespective of water depth. On the other hand, 24 triads are formed for a certain frequency in the left neighborhood of the primary blocking point, while thirty triads occur when the frequency is considered in the right neighborhood of the secondary blocking point for specific values of compressive force and density ratio in the case of deep water/short flexural gravity waves in both the layers. In addition, a new class of triad, which is rarely found in the case of surface gravity waves, occurs for a certain frequency within the blocking limits for a suitable choice of compressive force and density ratio in the case of waves in deep/intermediate upper layer depth.
Phase frustration induced remote synchronization
Authors: Yang Zhiyin , Chen Dehua , Xiao Qin , Liu Zonghua
Published: October 2022

Remote synchronization (RS) may take an important role in brain functioning and its study has attracted much attention in recent years. So far, most studies of RS are focused on the Stuart–Landau oscillators with mean-field coupling. However, realistic cases may have more complicated couplings and behaviors, such as the brain networks. To make the study of RS a substantial progress toward realistic situations, we here present a model of RS with phase frustration and show that RS can be induced for those systems where no RS exists when there is no phase frustration. By numerical simulations on both the Stuart–Landau and Kuramoto oscillators, we find that the optimal range of RS depends on the match of phase frustrations between the hub and leaf nodes and a fixed relationship of this match is figured out. While for the non-optimal range of RS, we find that RS exists only in a linear band between the phase frustrations of the hub and leaf nodes. A brief theoretical analysis is provided to explain these results.
Bilinguals produce language-specific voice onset time in two true-voicing languages
Authors: Souganidis Christoforos , Molinaro Nicola , Stoehr Antje
Published: October 2022

It is well established that early bilinguals who speak languages that differ in the phonetic implementation of the
voicing contrast have language-specific voicing systems. This study investigates voicing separation in bilinguals who speak two
true-voicing languages, Basque and Spanish. We also describe the voicing system in Gipuzkoan Spanish and Gipuzkoan Basque, which
is the closest dialect to Standard Basque and it has not yet been investigated experimentally. Twenty Basque-Spanish early
bilingual speakers of Gipuzkoan dialects participated in two picture naming tasks. We described their voicing system by measuring
voice onset time (VOT) in both Gipuzkoan Basque and Spanish, and used linear mixed-effects models to investigate between-language
production differences. Our results show for the first time that adult early bilinguals who speak two true-voicing languages
produce language-specific VOT in ‘voiced’ plosives. This finding demonstrates that bilinguals’ phonetic systems during production
are more fine-grained than previously assumed, and contributes to a deeper understanding of granularity in early bilingual
phonetic systems.

Published: October 2022

The in-situ synthesis of TiC reinforced Ni-based coatings were prepared on copper substrates by using precursor materials (TiFe and Cr3C2) by plasma cladding. The coating consisted mainly of γ-(Cu, Fe, Ni), TiC, CrB and Cr23C6. The generated TiC particles tend to float up to the upper part of the coating to aggregate and grow, so the TiC concentration in the upper part is larger. The hardness of the TiC composite coating is distributed in a gradient, and the average hardness is 700 HV, which is 13.0 times that of the copper matrix. The wear mechanism of TiC composite coating is abrasive wear, and the wear resistance is 13.0 times that of the copper substrate.

We discuss the discovery potential of JUNO experiment for neutrino lines from MeV dark matter (DM) annihilation and decay in a model-independent way. We find that JUNO will be able to give severe constraints on the cross section of DM annihilating into neutrinos and on the lifetime of DM decaying into neutrinos. More concretely, with 20 years of data-taking in the fiducial volume 17 kton, the cross section will be constrained smaller than 4 × 10-26cm3sec-1for the mass of a DM particle 15 MeV ≲mχ≲ 50 MeV at 90 % C.L., which might be strong enough to test thermal production mechanism of DM particles for such range of DM mass. The lifetime will be constrained as strong as 1 × 1024sec for the mass of a DM particlemχ≃ 100 MeV at 90 % C.L..

The evaporation of primordial black hole (PBH) via Hawking radiation influences the evolution of Inter Galactic Medium by heating up the latter and consequently affects the 21cm signal originated from the neutral Hydrogen atoms. In this work, we have considered EDGES observational data of 21cm line corresponding to cosmic dawn era to constrain the mass and the abundance of PBHs. In this context, two different PBH mass distributions namely, power law and lognormal mass distributions are considered to estimate the effects of PBH evaporation on the 21cm brightness temperature T
21. In addition to these two mass distributions, different monochromatic masses are also considered. The impacts of dark matter-baryon interactions on T
21 are also considered in this work along with the influences of PBH evaporation. Furthermore, adopting different monochromatic masses for PBHs, an attempt has been made to formulate a distribution for PBH masses by associating a probability weightage of the T
21 values (at z ∼ 17.2), within the range given by EDGES experiment, with the calculated T
21 values for each of the PBH mass values. The distribution best suited for the present purpose is found to be a combination of an error function and Owen function. Allowed contours in the parameter space of (initial PBH mass-dark matter mass) are obtained.

analytically is proved. For this purpose, positive solutions of the modified Helmholtz equation are applied instead of harmonic functions used in previous results. The resulting Kuran type theorem involves the volume mean value property of solutions to this equation. Other plausible inverse mean value properties of these solutions are discussed.

Background

Few studies have evaluated the association between changes in diet quality from mid-life to late-life and healthy ageing.

Methods

We included 12,316 Chinese adults aged 45–74 years at baseline (1993–1998) from the Singapore Chinese Health Study. Diet quality was measured using the Dietary Approaches to Stop Hypertension (DASH) scores at baseline and follow-up 3 interviews (2014–2016). Healthy ageing was assessed at follow-up 3 interviews, and was defined as absence of specific chronic diseases, good mental and overall self-perceived health, good physical functioning and absence of cognitive impairment, limitations in instrumental activities of daily living or function-limiting pain. Multivariable-adjusted logistic regression models were applied to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the association between changes in DASH scores and healthy ageing.

Results

Compared with participants who maintained relatively stable DASH scores, a >10% decrease in DASH score was associated with a 16% (95% CI, 4–26%) lower likelihood of healthy ageing, whereas a >10% increase in DASH score was associated with a 19% (95% CI, 3–37%) higher likelihood of healthy ageing. Compared with participants who were in the low-score group consistently, participants who increased their DASH scores from moderate-score at baseline to high-score at follow-up 3 had a 53% (95% CI, 21–92%) higher likelihood of healthy ageing, whereas those who were in the high-score group consistently had 108% (95% CI, 71–152%) higher likelihood of healthy ageing.

Conclusions

Improving diet quality from mid- to late-life was associated with a higher likelihood of healthy ageing.
k
mdiff, large-scale and user-friendly differential k-mer analyses
Authors: Lemane Téo , Chikhi Rayan , Peterlongo Pierre
Published: October 2022

Genome wide association studies elucidate links between genotypes and phenotypes. Recent studies point out the interest of conducting such experiments using k-mers as the base signal instead of single-nucleotide polymorphisms. We propose a tool, kmdiff, that performs differential k-mer analyses on large sequencing cohorts in an order of magnitude less time and memory than previously possible.

Altered synaptic connectivity in anin vitrohuman model of STXBP1 encephalopathy

Published: October 2022

Early infantile developmental and epileptic encephalopathies are devastating conditions, generally of genetic origin, but the pathological mechanisms often remain obscure. A major obstacle in this field of research is the difficulty of studying cortical brain development in humans, at the relevant time period in utero. To address this, we established an in vitro assay to study the impact of gene variants on the developing human brain by using living organotypic cultures of the human subplate and neighbouring cortical regions, prepared from ethically sourced, 14–17 post-conception week brain tissue (www.hdbr.org). We were able to maintain cultures for several months, during which time the gross anatomical structures of the cortical plate, subplate and marginal zone persisted, while neurons continued to develop morphologically and form new synaptic networks. This preparation thus permits the study of genetic manipulations and their downstream effects on an intact developing human cortical network. We focused on STXBP1 haploinsufficiency, which is among the most common genetic causes of developmental and epileptic encephalopathy. This was induced using shRNA interference, leading to impaired synaptic function and a reduced density of glutamatergic synapses. We thereby provide a critical proof-of-principle for how to study the impact of any gene of interest on the development of the human cortex.
