Sounding Plastic: The “Great Career” of the Flexidisc in Socialist Poland
Authors: Bohlman Andrea F.
Published: April 2024

This essay asks what archival sound objects—in this case a vast stockpile of bootleg music recordings—can tell us about cultures of listening and the cultivation of intimacy through sound under state socialism. It combines ethnographic and historical methodologies to analyze a format for popular music that circulated through an alternative economy in the People's Republic of Poland from the 1950s through the 1980s: the “sound postcard” (pocztówka dźwiękowa). These flimsy, often colorful, plastic rectangles contained copies of mainstream western, Polish, and Soviet popular musics on seven-minute records, sold hand-to-hand at markets and kiosks. In the twenty-first century, these polyethylene flexidiscs circulate as socialist ephemera with a nostalgic thrill, cherished for their obsolescence and provocative visual design reconstruct, but dismissed as poor fidelity transfers. I treat this archive as material history that contains aural traces allowing us to access socialities, affective experiences, and labor relations.
Introduction to Critical Discussion Forum: Socialist Sound Worlds
Authors: Cornish Gabrielle , Kendall Matthew
Published: April 2024

A lot happens when we press play. To prepare, we select a particular format of sound storage—maybe vinyl, magnetic tape, polyethylene, or an mp3—for the parsing, processing, and amplification of that format's content. Once things start moving, we inaugurate a listening experience that may seem effortless, but which has undergone meticulous social conditioning, and which is informed by our own deep histories of listening, aurality, and attention. In the long term, this process is not as rigid as it sounds: listening has always been flexible, and historians of the concert hall have told us a twisting and turning story about audiences who did not always think it was proper to stay silent, and who did not always feel the need to pay much attention to what took place in front of them. But today, anyone who chooses to play a spoken word compilation instead of a jazz LP (long-playing record) at a cocktail party might not find such a receptive crowd. Facilitated by internet streaming and downloading, this relatively new ability to amass intensely personal sonic archives often clashes with the contextual demands of where, when, and how certain forms of listening are meant to be enacted: the cocktail party often dictates a particular aural accompaniment, one more amenable to music than an audiobook. For such a widely practiced activity, why do the modern activities of storing, distributing, and amplifying sound, which have grown kaleidoscopically complex in the twentieth and twenty-first centuries, remain undertheorized in Slavic studies? What would it mean to think about these questions and their repercussions in east European modernity? And what might listening to east European history and culture tell us that our other senses cannot?

Published: April 2024

Previous research has found some peculiarities in sexual functioning of adults with attention deficit/hyperactivity disorder (ADHD). Using a set of questionnaires that had to be answered online, we assessed the prevalence of paraphilic fantasies and behaviors in a sample of 160 adults with ADHD in comparison to 75 adults without ADHD and evaluated the association between paraphilias and hypersexuality in the ADHD group. Both groups reported high rates of paraphilic fantasies and behaviors. ADHD individuals were more likely to report about very sexually arousing paraphilic fantasies (ADHD: 58.2% vs. non-ADHD: 40.5%; χ2 = 6.323, p = 0.01) and behaviors (ADHD: 44.9% vs. non-ADHD: 28.4%; χ2 = 5.774, p = 0.02). Furthermore, ADHD individuals reported on average about more very sexually arousing paraphilic behaviors compared to non-ADHD individuals (ADHD: M = 1.28, SD = 0.10 vs. non-ADHD: M = 0.81, SD = 0.09; T = 2.68, p < 0.01). Furthermore, in ADHD individuals both very sexually arousing paraphilic interests in masturbation fantasies (r(158) = 0.17, p = 0.03) and in sexual behaviors (r(158) =0.19, p = 0.02) showed a significant correlation with hypersexuality. In non-ADHD individuals no such significant correlation could be found. Altogether, it can be concluded that individuals with ADHD seem to be more prone to develop and act out paraphilic sexuality than those without ADHD, however, found differences were rather small. The results of the present study add to the current trend to depathologize paraphilic sexuality in the general as well as in clinical populations.
Identifying characteristics and clinical conditions associated with hand grip strength in adults: the Project Baseline Health Study
Authors: Taylor Kenneth A. , Carroll Megan K. , Short Sarah A. , Goode Adam P.
Published: April 2024

Low hand grip strength (HGS) is associated with several conditions, but its value outside of the older adult population is unclear. We sought to identify the most salient factors associated with HGS from an extensive list of candidate variables while stratifying by age and sex. We used data from the initial visit from the Project Baseline Health Study (N = 2502) which captured detailed demographic, occupational, social, lifestyle, and clinical data. We applied MI-LASSO using group methods to determine variables most associated with HGS out of 175 candidate variables. We performed analyses separately for sex and age (< 65 vs. ≥ 65 years). Race was associated with HGS to varying degrees across groups. Osteoporosis and osteopenia were negatively associated with HGS in female study participants. Immune cell counts were negatively associated with HGS for male participants ≥ 65 (neutrophils) and female participants (≥ 65, monocytes; < 65, lymphocytes). Most findings were age and/or sex group-specific; few were common across all groups. Several of the variables associated with HGS in each group were novel, while others corroborate previous research. Our results support HGS as a useful indicator of a variety of clinical characteristics; however, its utility varies by age and sex.
Quantifying the impact of homophily and influencer networks on song popularity prediction
Authors: Reisz Niklas , Servedio Vito D. P. , Thurner Stefan
Published: April 2024

Forecasting the popularity of new songs has become a standard practice in the music industry and provides a comparative advantage for those that do it well. Considerable efforts were put into machine learning prediction models for that purpose. It is known that in these models, relevant predictive parameters include intrinsic lyrical and acoustic characteristics, extrinsic factors (e.g., publisher influence and support), and the previous popularity of the artists. Much less attention was given to the social components of the spreading of song popularity. Recently, evidence for musical homophily—the tendency that people who are socially linked also share musical tastes—was reported. Here we determine how musical homophily can be used to predict song popularity. The study is based on an extensive dataset from the last.fm online music platform from which we can extract social links between listeners and their listening patterns. To quantify the importance of networks in the spreading of songs that eventually determines their popularity, we use musical homophily to design a predictive influence parameter and show that its inclusion in state-of-the-art machine learning models enhances predictions of song popularity. The influence parameter improves the prediction precision (TP/(TP $$+$$
+
FP)) by about 50% from 0.14 to 0.21, indicating that the social component in the spreading of music plays at least as significant a role as the artist’s popularity or the impact of the genre.

Detailed knowledge regarding the associations between intake of different types of seafood and meat and the risk of type 2 diabetes (T2D), and insight into possible mechanisms are warranted. In this study we aimed to evaluate the associations between intake of different types of seafood and meat and the subsequent risk of T2D using the Norwegian Mother, Father, and Child Cohort Study (MoBa), and furthermore, by using a mouse model to gain further insight into possible molecular mechanisms contributing to the associated metabolic changes. Women in MoBa who were free of pharmacologically treated diabetes at baseline (n = 60,777) were prospectively evaluated for incident T2D, identified on the basis of medication usages > 90 days after delivery, ascertained by the Norwegian Prescription Database. Dietary intake was obtained with a validated 255-item food frequency questionnaire which assessed habitual diet during the first 4–5 months of pregnancy. Metabolic phenotypes and plasma metabolome were investigated in female mice fed isocaloric diets with different types of seafood and meat mimicking the dietary intake in the human cohort. During maximum 10-year and mean (SD) 7.2 (1.6) years follow-up time, 681 (1.1%) women developed pharmacologically treated T2D. All statistical models identified a higher risk of T2D with increased shellfish intake, whereas no associations were observed for total seafood, fatty fish, total meat and red meat in the adjusted models. In mice, the shellfish-based western diet induced reduced glucose tolerance and insulin secretion compared to the diet based on lean fish, and we identified a number of metabolites elevated in plasma from shellfish-fed mice that correlated with glucose intolerance. Mice fed a western diet based on meat also exhibited reduced glucose tolerance in comparison to lean fish fed mice, whereas mice fed fatty fish, total seafood or red meat did not differ from lean fish fed mice. We observed a diet-specific metabolic signature in plasma demonstrating five distinct metabolite profiles in mice fed shellfish, fatty fish, total seafood/lean fish, a mixed diet and meat. In conclusion, these findings demonstrate that different types of seafood have different outcome on T2D risk. In women, intake of shellfish was associated with higher risk of T2D. In female mice, a shellfish enriched diet reduced glucose tolerance and altered the abundance of several distinct plasma metabolites correlating with glucose tolerance.

Published: April 2024

Durability is one of the technical bottlenecks restricting fuel cell electric vehicle development. As a result, significant time and resources have been invested in research related to this area worldwide. Current durability research mainly focuses on the single cell and stack levels, which is quite different from the usage scenarios of actual vehicles. There is almost no research on developing durability test cycles on the fuel cell system level. This paper proposes a universal model for developing a durability test cycle for fuel cell system based on the China automotive test cycle. Large-scale comparison tests of the fuel cell systems are conducted. After 1000 h test, the output performance degradation of three mass-produced fuel cell system is 14.49%, 9.59%, and 4.21%, respectively. The test results show that the durability test cycle proposed in this paper can effectively accelerate the durability test of the fuel cell system and evaluate the durability performance of the fuel cell system. Moreover, the methodology proposed in this paper could be used in any other test cycles such as NEDC (New European Driving Cycle), WLTC (Worldwide Harmonized Light Vehicles Test Procedure), etc. And it has comprehensive application value and are significant for reducing the cost of durability testing of fuel cell systems and promoting the industrialization of fuel cell electric vehicles.
Sand cat swarm optimization algorithm and its application integrating elite decentralization and crossbar strategy
Authors: Li Yancang , Yu Qian , Du Zunfeng
Published: April 2024

Sand cat swarm optimization algorithm is a meta-heuristic algorithm created to replicate the hunting behavior observed by sand cats. The presented sand cat swarm optimization method (CWXSCSO) addresses the issues of low convergence precision and local optimality in the standard sand cat swarm optimization algorithm. It accomplished this through the utilization of elite decentralization and a crossbar approach. To begin with, a novel dynamic exponential factor is introduced. Furthermore, throughout the developmental phase, the approach of elite decentralization is incorporated to augment the capacity to transcend the confines of the local optimal. Ultimately, the crossover technique is employed to produce novel solutions and augment the algorithm's capacity to emerge from local space. The techniques were evaluated by performing a comparison with 15 benchmark functions. The CWXSCSO algorithm was compared with six advanced upgraded algorithms using CEC2019 and CEC2021. Statistical analysis, convergence analysis, and complexity analysis use statistics for assessing it. The CWXSCSO is employed to verify its efficacy in solving engineering difficulties by handling six traditional engineering optimization problems. The results demonstrate that the upgraded sand cat swarm optimization algorithm exhibits higher global optimization capability and demonstrates proficiency in dealing with real-world optimization applications.

A theoretical view of the T-web statistical description of the cosmic web
Authors: Ayçoberry Emma , Barthelemy Alexandre , Codis Sandrine
Published: April 2024

Context. The objective classification of the cosmic web into different environments is an important aspect of large-scale structure studies, as it can be used as a tool to study the formation of structures (halos and galaxies) in mode detail, and it forms a link between their properties and the large-scale environment; these different environments also offer another class of objects whose statistics contain cosmological information.

Aims. In this paper, we present an analytical framework to compute the probability of the different environments in the cosmic web based on the so-called T-web formalism, which classifies structures into four different classes (voids, walls, filaments, and knots) based on the eigenvalues of the Hessian of the gravitational potential, often called the tidal tensor.

Methods. Our classification method relies on studying whether the eigenvalues of this Hessian matrix are above or below a given threshold and thus requires knowledge of the joint probability distribution of those eigenvalues. We performed a change of variables in terms of rotational invariants, which are polynomials of the field variables and minimally correlated. We studied the distribution of those variables in the linear and quasi-linear regimes with the help of a so-called Gram-Charlier expansion, using tree-order Eulerian perturbation theory to compute the Gram-Charlier coefficients. This expansion then allowed us to predict the probability of the four different environments as a function of the chosen threshold and at a given smoothing scale and redshift for the density field. We checked the validity regime of our predictions by comparing those predictions to measurements made in the N-body Quijote simulations.

Results. Working with fields normalised by their linear variance, we find that scaling the threshold value with the non-linear amplitude of fluctuations allows us to capture almost the entire redshift evolution of the probabilities of the four environments, even if we assume that the density field is Gaussian (corresponding to the linear regime of structure formation). We also show that adding mild non-Gaussian corrections with the help of a Gram-Charlier expansion – hence introducing corrections that depend on third-order cumulants of the field – provides even greater accuracy, allowing us to obtain very precise predictions for cosmic web abundances up to scales of as small as ∼5 Mpc h−1 and redshifts down to z ∼ 0.
A comprehensive X-ray analysis of the massive O-type binary HD 93250 over two decades
Authors: Arora Bharti , De Becker Michaël , Pandey Jeewan C.
Published: April 2024

Context. Massive star winds are known to be responsible for X-ray emission arising from wind plasma heated by the strong shocks up to temperatures of 106–107 K in the case of colliding wind binaries. The investigation of X-ray emission from massive stars thus constitutes a valuable tool for identifying binaries, which is otherwise a difficult task using classical techniques.

Aims. We investigated thermal and nonthermal X-ray emission from the massive O-type star HD 93250 to unveil its binary orbital parameters independently.

Methods. To meet our goal, we analyzed X-ray data obtained with European Photon Imaging Camera on board XMM-Newton spanning over ~19 yr. Additionally, we analyzed NuSTAR observations of HD 93250 taken at various epochs.

Results. We determine the variability timescale of the X-ray emission to be 193.8±1.3d, in full agreement with the 194.3±0.4d period derived from the astrometric orbit. The X-ray spectrum of HD 93250 is well explained by a three-temperature thermal plasma emission model with temperatures of 0.26, 1.0, and 3.3 keV. The resulting X-ray flux varies in compliance with the typical colliding wind emission from eccentric massive binaries where it enhances near periastron passage and decreases gradually close to apastron in proportion to the inverse of the binary separation. The periastron-to-apastron X-ray emission ratio points to an eccentricity range of 0.20–0.25, once again in agreement with the previously determined astrometric orbit. Finally, we do not detect any hard X-ray emission attributable to nonthermal emission above 10 keV.

Conclusions. Given the derived plasma temperature, the strong phase-locked variability, and the significant over-luminosity in X-rays, we establish that the X-ray emission from HD 93250 is dominated by the colliding-wind region. Our results lend support to the idea that X-ray time analysis of massive stars constitutes a relevant tool for investigating their multiplicity and for extracting relevant information on their basic orbital parameters – such as period and eccentricity – independently of any orbital solution derived from classical techniques.

Aims. We undertake a project to reexamine microlensing data gathered from high-cadence surveys. The aim of the project is to reinvestigate lensing events whose light curves exhibit intricate anomaly features that are associated with caustics, but lack prior proposed models that would explain these features.

Methods. Through detailed reanalyses considering higher-order effects, we determined that it is vital to account for the orbital motions of lenses to accurately explain the anomaly features observed in the light curves of the lensing events OGLE-2018-BLG-0971, MOA-2023-BLG-065, and OGLE-2023-BLG-0136.

Results. We estimated the masses and distances to the lenses by conducting Bayesian analyses using the lensing parameters of the newly found lensing solutions. These analyses showed that the lenses of the events OGLE-2018-BLG-0971 and MOA-2023-BLG-065 are binaries composed of M dwarfs, while the lens of OGLE-2023-BLG-0136 likely is a binary composed of an early K-dwarf primary and a late M-dwarf companion. For all lensing events, the probability that the lens resides in the bulge is considerably higher than that it is located in the disk.
Existence of bounded solutions to multiplicative poisson equations under mixing property
Authors: Pitera Marcin , Stettner Łukasz
Published: April 2024

We study the problem of Multiplicative Poisson Equation (MPE) bounded solution existence in a generic probabilistic discrete-time setup with preimposed mixing. In particular, we consolidate results based on the span-contraction framework and derive an explicit sharp bound that must be imposed on the cost function to guarantee the existence of a bounded MPE solution under mixing. Also, we study properties that the probability kernel must satisfy to ensure the existence of an MPE solution for any generic risk-reward function and characterise process behaviour in the complement of the invariant measure support. Finally, we present numerous examples and stochastic dominance based arguments that help to better understand the problems that arise when the mean is replaced by the entropy in the ergodic setup.
Comparison of Early Childhood Education Programs between Eastern and Western Countries
Authors: Zhou Xiaochen , Lu Xue
Published: April 2024

With the rapid development of China’s economy and society, the core of national competitiveness has shifted from material elements to talents, systems, and innovation. Ultimately, it is a talent problem, that is, the problem of improving population quality. Only by striving to improve the quality of the population can we leverage our strong advantages in human resources and transform China from a populous country to a human capital powerhouse. Early childhood development and education are important ways and key links to improve population quality. This paper adopts literature research, empirical analysis, and quantitative analysis methods to conduct a comparative analysis of education programs in Eastern and Western countries around the topic of early childhood development education. The results indicate that the early childhood education and care (ECEC) policies and programs in Western countries have similar origins, both aimed at better protecting children, providing early education to children with special needs, and ensuring the social participation of mothers in the labor force. Although there are similarities in the formulation and implementation of program goals and policies, there are significant differences in other aspects. However, China’s early education faces problems such as insufficient local financial support, high costs, unequal access to opportunities, and significant differences in the quality of services. In the future, it is necessary to increase investment in early childhood development education, and the whole society should participate and carry out early childhood development education together.
Effective analysis of translanguaging pedagogy for learning English in China
Authors: Yan Xintong
Published: April 2024

This research investigated the applicability of translanguaging as a teaching strategy in China’s K-12 English learning context. Using a qualitative research method of systematic literature review informed by a social constructivist paradigm, data from 15 peer-reviewed articles were analyzed. The findings indicate that translanguaging serves as an effective pedagogical approach in K-12 EFL education. However, potential resistance from teachers and students may arise due to its novelty in the Chinese educational system. Implementing translanguaging can diminish rote learning, create a flexible linguistic environment, and address the identity challenges of bilingual or multilingual learners. The results suggest a paradigm shift in K-12 English education in China, advocating for translanguaging as an enriching instructional strategy.

Legal Ethics and Professional Responsibility in the Legal Profession
Authors: Xu Jingwei , Li Zhengmin , Li Siyu
Published: April 2024

This article delves into the critical importance of legal ethics and professional responsibility in the legal profession, emphasizing their role in upholding justice and societal trust. Legal ethics provide a comprehensive framework for lawyers to maintain professionalism, integrity, and competence. Integrity requires honesty and transparency, while competence demands continuous learning to navigate evolving legal landscapes. Lawyers also have a duty to maintain client confidentiality and avoid conflicts of interest. Professional responsibility extends beyond individual cases, encompassing obligations to clients, the courts, and society. Lawyers must act in their clients’ best interests and uphold the integrity of the legal system. Additionally, they play a role in promoting access to justice and the rule of law. Challenges brought by technology, globalization, and shifting societal norms require lawyers to adapt while preserving core ethical values. Continuous education and robust regulatory frameworks are vital for ensuring adherence to ethical standards and professional responsibilities. The legal profession’s ability to evolve and uphold these principles is crucial for its continued role in safeguarding justice and societal trust.

An online survey was administered in China by recruiting 413 youth participants. The results demonstrated that traditional media attention and social media attention were positively associated with attitude, subjective norms, perceived behavioral control, injunctive norms, and descriptive norms. Next, attitude, subjective norms, and descriptive norms positively affect individuals’ behavioral intention to perform basketball sports. Building on the theory of planned behavior, our research examines the role of the media as a precursor to attitudes, subjective norms, and perceived behavioral control, with an in-depth examination of how normative pressures shape individuals’ intentions to act. It also examines the practical implications.
Influencing Factors of Female Managers’ Leadership in Vocational Education and Training
Authors: Gao Lin
Published: April 2024

With the changing development of today’s societies, leadership and management issues are gaining more and more attention. Especially in the management structure, gender is unequally distributed, while women are less frequently represented in management positions and are less represented in management positions. Gender theory states that women are in the main position on an equal footing with men in social development and promote a development-promoting view of women, which corresponds to the focus pursued here. From this perspective, we examine the potential for women in vocational education to promote good professional careers by putting forward the factors influencing the leadership of executives in vocational education and strategies for promoting strategies against it. Not only theoretical research is of immense interest for practice.

Research review of workplace negative gossip
Authors: Liu Yang
Published: April 2024

workplace negative gossip refers to the informal and negative evaluation and discussion of thirdparty members who are not present when members of the organization communicate with each other. As a manifestation of workplace ‘cold’ violence, workplace negative gossip has the characteristics of concealment, difficulty in tracing back to the source, and rapid dissemination. The research on the antecedents of workplace negative gossip mainly focuses on the individual, interpersonal and organizational levels. The research on the negative gossip outcome variables in the workplace can be divided into its effect on employees’ cognition, emotion, behavior and performance and its mechanism. The research in this field is very important for seeking effective countermeasures to control workplace negative gossip and improving organizational management methods.

Temporary Migrants’ Reactions to Immigration-related Content on Social Media Platform: Taking Australian Chinese Temporary Migrants on Red (Xiaohongshu) as An Example
Authors: Jing Yuwen
Published: April 2024

This study examines the impact of RED (Xiaohongshu), a Chinese social media platform, on the perceptions and experiences of Australian Chinese temporary migrants regarding immigration. Using a qualitative approach with semi-structured interviews and guiding by Actor-Network Theory (ANT), the research focuses on interactions within the RED network involving the platform, immigration-related content, and users. It explores how algorithms and user-generated content (UGC) on RED affect information consumption, decision-making, and community engagement among migrants. The findings highlight a nuanced interplay between agency-driven content and personal narratives, both shaping users’ understanding of immigration. The study emphasizes the dual role of algorithms in content filtering and the importance of accessing diverse information sources for a well-rounded comprehension of immigration issues. RED offers valuable insights and a space for experience-sharing, yet its impact is influenced by algorithmic constraints and the subjective nature of UGC. The research advocates critical information consumption and a holistic approach in engaging with social media on sensitive topics like immigration.
Antitrust Regulation of Self-Preferential Behavior of Digital Platform Operators in China
Authors: Li Ruoyao
Published: April 2024

In the past two decades, the platform economy has been developing rapidly, and while creating great welfare for the society, it is easier to form a monopoly pattern due to its multilateral nature, price asymmetry and economy of scale. Some digital platforms with a dominant market position have implemented self-preferential behaviors based on their dual roles as market organizers and market operators, disrupting the order of free competition, making it necessary to impose antitrust regulation on them. This paper analyzes the current status of antitrust regulation of self-preferential behavior of digital platforms in China and finds that it is still in its infancy, and there are dilemmas such as deficiencies in the relevant market definition methods, the existing types of abuse of dominant position of market dominance not being able to cover all selfpreferential behaviors, and the lack of experience in and high difficulty of law enforcement. In response to these difficulties, China can improve the relevant market definition methods, add new types of abuse of dominant market position, and introduce the settlement mechanism to improve the antitrust regulation of selfpreferential behaviors of digital platform operators, and ultimately promote the healthy and prosperous development of the platform economy.
How rarity and exclusivity influence types of perceived value for luxury
Authors: Wang Xujia , Sung Billy , Phau Ian
Published: April 2024

The purpose of this study is to investigate how exclusivity and rarity (natural versus virtual) influence consumers’ perceived value (functional, social and emotional) for luxury. Data were collected through an online panel. Luxury product categories including bags, wines, shoes and jewellery were selected as research stimuli. Structural equation modelling was used to test the hypotheses. Results showed that perceived natural rarity was a positive and significant predictor for all three types of consumers’ perceived value and across all four product categories. Perceived virtual rarity was a positive and significant predictor only for perceived functional value. Perceived exclusivity did not show any significant effects on value across all categories. This study is the first to provide theoretical support that exclusivity and rarity may have different functions in luxury marketing implementations. It provides updated empirical evidence showing traditional marketing tactic, such as natural rarity, still receive positive social and emotional evaluations among contemporary consumers.
Revisiting fulgide photochromism: Mechanistic decoding and electron transport from computational exploration
Authors: Medhi Biman , Nath Upasana , Sarma Manabendra
Published: April 2024

The photochromic behavior of the fulgide molecule relies on ring-closure and ring-opening processes involving conical intersections during excited state transformation between isomers. The precise location and topography of these conical intersections significantly shape the decay process and fluorescence phenomena inherent to the molecule. This work combines electronic structure theory calculations using the density functional theory and wavefunction methods, as well as surface hopping simulation to analyze the photochemical behavior of an experimentally synthesized fulgide molecule, (E)-p-methylacetophenylisopropylidenesuccinic anhydride (1E). Our study reveals the conical intersection between the first excited state (S1) and the ground electronic state (S0), which emerges beyond the S1 minimum of 1E to the ring-closing side. The distinctive topography of this conical intersection appears to be sloped. These findings suggest a reduced quantum yield for the formation of the closed isomer, indicating a higher likelihood of reformation of the open isomer(s). The surface hopping simulation further supports this observation, revealing a mere ∼8% quantum yield for the formation of the closed isomer. In addition, the photoisomerization of the fulgide molecule initiates a cascade of conduction switching and holds great potential for applications in molecular electronics. Delving into the realm of molecular electronics, we have further examined the electron transport properties, disclosing the higher conductivity of the closed isomer.

Published: April 2024

We present comprehensive numerical results from a study of model H, which describes phase separation kinetics in binary fluid mixtures. We study the pattern dynamics of both density and velocity fields in d = 2, 3. The density length scales show three distinct regimes, in accordance with analytical arguments. The velocity length scale shows a diffusive behavior. We also study the scaling behavior of the morphologies for density and velocity fields and observe dynamical scaling in the relevant correlation functions and structure factors. Finally, we study the effect of quenched random field disorder on spinodal decomposition in model H.
