Concentrated aqueous solutions of multivalent macroions enhance the electrical double layer capacitance and differential capacitance of a planar supercapacitor

The electrostatic properties of the ionic cloud, or electrical double layer, neutralizing a charged electrode are relevant to improve the storage of electrical energy and the efficiency of supercapacitors and/or batteries using coulombic fluids. In this work, we study the microscopic profiles of charged particles, integrated surface charge density, and the mean electrostatic potential associated to a pair of infinite parallel plates uncharged or, else, with opposite charge, in the presence of a salt-free aqueous solution constituted by big positive macroions and small anions, which interact via an explicit electrostatic coulombic potential and are dissolved in an implicit solvent. The particle profiles and the integrated surface charge density associated to Monte Carlo simulations and integral equations theory display an oscillatory or non-monotonic behaviour producing the phenomena of charge inversion and charge reversal. These phenomena are not predicted by the non-linear Poisson-Boltzmann equation, which highlights the importance of ion correlations and ionic volume excluded effects. The phenomenon of surface charge amplification is observed near the point of zero charge, which is yielded by the particle size-asymmetry. For a fixed concentration of macroions, a monotonic increase of the mean electrostatic potential difference between the charged parallel plates is predicted by simulations and theories as a function of the electrodes' charge. For a fixed surface charge density, the capacitance of the parallel plates capacitor increases when the ionic strength of the macroion's solution increases. A concavity inversion and an augment of the differential capacitance is also observed for an electrode near the point of zero charge as function of the macroion's concentration.

A multi-method study of interpersonal complementarity and mentalization

Research finds cross-sectional relationships between mentalizing impairments and maladaptive personality traits. The current study connects mentalizing impairments to dynamic interpersonal processes using a multi-method design. A sample of 218 participants completed the Movie for the Assessment of Social Cognition (MASC; Dziobek et al., 2006) to assess mentalizing ability. Subsequently, participants rated their agentic and communal behavior and their perception of interaction partners’ agentic and communal behavior over 21-days. Mentalizing ability moderated the within-person relationship between behavior and perception for both agency and communion. Worse performance on the MASC was associated with weaker interpersonal complementarity, suggesting that mentalizing impairments lead to deviations from expected patterns of behavior and perception across interpersonal situations. These findings confirm the assumption of Contemporary Integrative Interpersonal Theory that mentalization impairments can disrupt normative interpersonal processes (Cain et al., 2024; Pincus & Hopwood, 2012).

Analysis of a nonlinear model for the thermoelastic beam

This paper addresses the Cauchy problem associated with the nonlinear thermoelastic beam featuring thermal dissipation. We examine the problem in an open domain, which may be either bounded or unbounded. The existence of a solution is derived through the diagonalization theorem for self-adjoint operators using Hilbertian integral theory.

We solve the form factor bootstrap axioms for the branch-point twist fields and obtain the deformed form factors. Using these form factors, we compute the deformed von Neuman entropy up to two particle contributions. The solution of the form factor axioms is not unique. We find that for the simplest solution of the bootstrap axioms, the UV limit of the entanglement entropy takes the same form as the undeformed one, but the effective central charge is deformed. For solutions with additional CDD-like factors, we can have different behaviors. The IR corrections, which only depends on the particle spectrum is untouched.

Unveiling the Black Box in Retail Firms’ Supply Chain Labor Standards Performance: A Theory of Supply Chain Labor Compliance Integration

Prior work shows limited success in retail firms’ efforts to create socially responsible supply chains by enforcing suppliers’ compliance with labor standards, partly due to conflicting sourcing demands exerted on the supplier by siloed functional units within the retail firm. To ensure the substantive adoption of labor standards throughout its supply chain, we argue that the retail firm must improve their degree of “supply chain labor compliance integration” by minimizing cross-functional tensions in human capital, identities, processes and goals. We define supply chain labor compliance integration, identify its determinant organizational practices that reduce cross-functional tensions, and explain the mechanisms by which it improves the retail firm’s supply chain labor standards performance. This work offers theoretical and practical insights on the retail firm’s capacity for managing socially responsible supply chains, and more broadly, on how systematically minimizing intra-organizational tensions arising in the pursuit of competing organizational priorities is a prerequisite for their simultaneous execution in inter-organizational business exchanges.

Learning Newtonian mechanics with an intrinsically integrated educational game

AbstractBackgroundResearch on cognitive effects of educational games in general shows promising results. However, there are large variations in learning outcomes between individual educational games. Research on the design process and different design elements of educational games has led to some interesting directions, but some design aspects remain unclear.ObjectivesWe examined how an educational game designed on the basis of intrinsic integration theory, based on a strong alignment between game and learning goals, supports the learning of Newtonian mechanics.MethodsThis study applied a mixed‐methods approach (N = 223). A pre‐ and post‐test design was used to examine possible learning and transfer effects fostered by playing the educational game, Newton's Race. To examine how players played the game, log data for each player were digitally recorded during gameplay.Results and ConclusionsOur findings demonstrated a significant positive learning effect of Newton's Race (p = 0.003, d = 0.201). This can be explained through the acquired log data. Log data show that players' gameplay mostly matched expected learning during the game, with physically correct game settings occurring more and more as gameplay progressed. The ability to transfer learned knowledge to other situations was shown to be limited to situations closely resembling the game environment.ImplicationsSimilarly, designed intrinsically integrated games on different (physics) subjects could also foster learning in a relative short time. To foster transfer to other situations we propose embedding the game within other instructional activities.

Comparative study of riemann integral and lebesgue integral in calculus

The aim of this research paper is to provide a comprehensive comparison between Riemann integral and Lebesgue integral. Integration is described as the inverse process of differentiation, which is used to determine the original function. Riemann integration is a specific type of definite integral applied to find the exact area under a function graph between two limits in a closed interval. Lebesgue integration, on the other hand, provides a more generalized framework for integration theory. Integrals are essential in mathematical modelling and analysis tools. Studying and comparing the similarities and differences between these two integration methods can help us better understand the essence and properties of integrals, so as to more accurately apply integration methods to solve practical problems. This paper provides a systematic analysis of the basics, definitions, concepts, and properties of Riemann integral and Lebesgue integral. Reasoning, proofs, and examples are consolidated to explain the properties and characteristics of these two integral methods. Finally, this paper explores the strengths and limitations of each integration methods, summarising their advantages and applicability to practical problems and providing insights into their respective computational methods and applicability in different contexts.

Form factors of the tricritical three-state Potts model in its scaling limit

We compute the form factors of the order and disorder operators, together with those of the stress–energy tensor, of a two-dimensional three-state Potts model with vacancies along its thermal deformation at the critical point. At criticality, the model is described by the non-diagonal partition function of the unitary minimal model M6,7 of conformal field theories and is accompanied by an internal S 3 symmetry. The off-critical thermal deformation is an integrable massive theory that is still invariant under S 3. The presence of infinitely many conserved quantities, whose spin spectrum is related to the exceptional Lie algebra E 6, allows us to determine the analytic S-matrix, the exact mass spectrum and the matrix elements of local operators of this model in an exact non-perturbative way. We use the spectral representation series of the correlators and the fast convergence of these series to compute several universal ratios of the renormalization group.

Reflective vortex focusing for acoustic contact-free object rotation

The use of acoustic vortex waves with angular momentum is a promising means of transferring mechanical torque to an object without making any physical contact. However, the existing passive-conversion vortex lenses are unable to produce strong acoustic radiation torque. To address this issue, we propose a flat reflector sculpted by spiral grooves. It reflects and converts incident waves into vortex-focusing waves that generate radiation torque. Compared with a transmission-type lens, a reflection-type vortex focusing plate exhibits superior functionality in converging sound waves and creating a stronger circular intensity flow. In this work, we analyze the vortex-focusing sound by Rayleigh-Sommerfeld integral theory and boundary element simulation, confirmed by experiments. The number, depth and direction of spiral grooves determine the topological charge, focusing intensity and torque direction, respectively. We evaluate the local and total acoustic radiation forces and torques, acting on small and large fixed spherical targets in the vortex-focusing beam. As a result, spinning a centimeter-size origami pinwheel several times larger than the wavelength at 40 kHz is realized without direct contact, by utilizing the enhanced acoustic radiation torque converged by the reflector. This technology enables efficient convergence of acoustic waves and simultaneous contactless transfer of mechanical torque to an object, thereby presenting potential applications in sound energy harvesting and wireless power supplies.

Online Sale of Pirated Books from a Legal and Moral Perspective

The increase in online book sales without permission and copyright violations in Indonesia poses a major threat to written works. This problem requires normative legal and moral studies to find solutions that complement previous research. This article aims to analyze and describe the legal regulations for buying and selling pirated books online and explain that the act of pirating books for sale is a moral crime. Normative legal research was used, which produced prescriptive conclusions. The data in this article consists of the Copyright Law, Information and Electronic Transactions Law, and other technical regulations. These regulations are equipped with various supporting references that discuss copyright issues, moral rights, and integrative legal theory, which describes a comprehensive legal system for responding to regulatory violations. This article reveals that national legal policies are not sufficient to guarantee protection for authors and publishers against book piracy and even make it difficult to report this crime to the police so that the use of the criminal justice system becomes ineffective. Indonesian society's perception of book piracy must be improved from previously being a common practice to a moral crime that is financially detrimental, and to the good name of authors and publishers. This article suggests several changes to the regulatory structure. First, we determine the authenticity verification scheme for books sold in bookstores and on marketplace platforms. Second, eliminating the concept of Klach Delict in criminal provisions so that reporting the crime of book piracy can be done by anyone, especially publishers and the public, who observe copyright.

Dispersive shock wave structure analysis for the defocusing Lakshmanan–Porsezian–Daniel equation

Via the finite-gap integration theory, we study the defocusing Lakshmanan–Porsezian–Daniel (LPD) equation. Meanwhile, we derive the degenerate forms for the single-phase periodic solution. In addition, we obtain the basic and combined structures of the dispersive shock wave through the Whitham modulation equation parameterized by the Riemann invariant.

Validity of information integration based on subjective and physiological data from a real sports condition: application to the judgment of fatigue in sport.

The objective of the present study was to confirm the convergent validity of information integration theory in the judgment of fatigue in sport, using information integration, subjective, and physiological data. Twenty healthy athletes were confronted with six cycling scenarios in two experimental conditions. In the laboratory condition, the athletes imagined the scenarios and had to cognitively combine the exercise intensity (30%, 50%, and 70% of the maximal intensity) and the exercise duration (15 and 30 min) when judging their expected level of fatigue. In the real sports condition, the athletes enacted each scenario and then rated their subjective fatigue. The heart rate was recorded continuously, so that the physiological training impulse could be calculated. We applied analyses of variance to the data and analyzed correlations between variables. The information integration data from the laboratory condition, the subjective data from the real sports condition, and the objective (physiological) data from the real sports condition were strongly correlated. The information integration patterns concerning fatigue as a function of the exercise duration and intensity obtained respectively from the three data sets were extremely similar.

As such, it seeks to provide new insights into the impact ofcultural exposure on intercultural learning. The results of the research suggest the need for a refinement of Kim’s theory. The findings also have implications for the policy and practice of educational institutions involved in study abroad programmes.

Multisensory mechanisms of gait and balance in Parkinson's disease: an integrative review.

Understanding the neural underpinning of human gait and balance is one of the most pertinent challenges for 21st-century translational neuroscience due to the profound impact that falls and mobility disturbances have on our aging population. Posture and gait control does not happen automatically, as previously believed, but rather requires continuous involvement of central nervous mechanisms. To effectively exert control over the body, the brain must integrate multiple streams of sensory information, including visual, vestibular, and somatosensory signals. The mechanisms which underpin the integration of these multisensory signals are the principal topic of the present work. Existing multisensory integration theories focus on how failure of cognitive processes thought to be involved in multisensory integration leads to falls in older adults. Insufficient emphasis, however, has been placed on specific contributions of individual sensory modalities to multisensory integration processes and cross-modal interactions that occur between the sensory modalities in relation to gait and balance. In the present work, we review the contributions of somatosensory, visual, and vestibular modalities, along with their multisensory intersections to gait and balance in older adults and patients with Parkinson's disease. We also review evidence of vestibular contributions to multisensory temporal binding windows, previously shown to be highly pertinent to fall risk in older adults. Lastly, we relate multisensory vestibular mechanisms to potential neural substrates, both at the level of neurobiology (concerning positron emission tomography imaging) and at the level of electrophysiology (concerning electroencephalography). We hope that this integrative review, drawing influence across multiple subdisciplines of neuroscience, paves the way for novel research directions and therapeutic neuromodulatory approaches, to improve the lives of older adults and patients with neurodegenerative diseases.

Contemporary civil society is dealing with an issue of how to deal with different cultures. This issue has led to the emergence of different views and opinions to discuss the relationship between society and different cultures on the one hand, and the relationship between diverse cultures themselves Different theories of cultural differences Some of these theories are about the merging and assimilation of minority cultures into the idol of high cultural values, including traditional or holistic assimilation theory, fragmentary assimilation theory, cultural integration theory, and cultural freedom or multicultural theory It opens up cultural freedoms and their protection, how these theories work and their relationship to the unity of society and state security, as well as different views on these theories with their approval or rejection and their arguments. Contemporary civil society's exposure to these theories has had different effects on both the collective level of groups and minorities and the individual level, as some groups or individuals have been willing to assimilate, culturally integrate, or preserve their own culture and values According to multicultural theory, different cultures can live without conflict and become the basis for coordination, development, social unity and preservation of the integrity of the state.

REBT와 MBCT의 비교 연구

The purpose of this study is to clarify the relationship between MBCT (Mindfulness-Based Cognitive Therapy) and REBT (Rational Emotive Behavior Therapy) theories by comparing them, and to provide theoretical basis for counselors dealing with various psychological problems to apply appropriately in the field. For this purpose, this study reviewed previous studies based on REBT and MBCT theories, compared and analyzed the core concepts of the theories and the characteristics of counseling and programs, and examined the domestic research trends of the last 10 years. The conclusions are as follows: First, both theories emphasize self-acceptance and caution against critical judgment. Second, they utilize a cognitive approach that recognizes the influence of personal thoughts, beliefs, and attitudes on emotions and behaviors. Third, they emphasize therapeutic change at a fundamental philosophical level. Fourth, they highlight the importance of presenting tasks to encourage self-therapy and self-help. Fifth, they approach the effectiveness of the therapy process psychologically and educationally. The implications drawn from the research trends of REBT and MBCT are as follows: First, the value of REBT as an integrative theory is proven. Second, programs integrating REBT with other therapies can help students in their academics and school life. Third, the development and efficacy of group counseling programs based on REBT have been demonstrated. Fourth, practical theories, tools, and qualitative analysis of experiences necessary for REBT counseling provide help to counselors. Fifth, research related to REBT supervision helps counselors develop their competencies. Sixth, MBCT not only prevents depression but also has positive effects on reducing anxiety and suicidal thoughts. This study is significant in that it contributes to the clinical application and advancement of cognitive behavioral therapy in Korea by comparing and analyzing REBT and MBCT, clarifying their relationship, and understanding research trends.

The multilevel well‐being paradox: Towards an integrative process theory of coping in teams

SummaryContemporary work teams are increasingly faced with external pressures and changing demands that thrust them into stressful conditions that require coping to maintain not only performance but also well‐being. In this paper, we treat the COVID‐19 pandemic as an extreme case of multilevel stressors and coping in teams to investigate how teams and their members simultaneously cope with stressors at both individual and team levels and the impacts this has on their well‐being. We conducted a longitudinal qualitative multi‐case study involving 12 teams, utilizing data from 69 members collected through diaries, interviews, and surveys over a period of 6 months. Our findings illustrate how the needs and coping efforts of teams and individuals can sometimes conflict, resulting in opposing states of well‐being at different levels. We frame this phenomenon as the multilevel well‐being paradox. Our emergent process model of multilevel coping in teams suggests that teams thrive when they establish a shared appraisal of stressors and coping options through active team reflection, and when they adopt coping approaches that align with the specific stressors experienced at both levels. This study advances our understanding of coping in teams by illuminating the intricate interplay between team and individual well‐being and highlighting the paradoxical nature of this relationship.

For the polynomial vector fields on a Clifford n-dimensional torus, we develop a Darboux theory of integrability. Moreover, we study the optimal maximum number of invariant meridians in terms of the degree of the polynomial vector field.

Psychological mechanism and cognitive basis of humorous speech

To more clearly present the psychological mechanism and cognitive basis of humorous speech, this study measured college students using various scales, discussed the role of humorous coping in resolving their social anxiety and regulating their mental health, and attempted to construct a cognitive symbol working model from three dimensions: theory of innocence, modern semiotics, and conceptual integration theory. We used the proposed model to present the psychological mechanism and cognitive basis of humorous speech. This study found that humor coping is positively correlated with college students’ social anxiety, which is positively correlated with mental health. Affinity humor style and humor coping can positively predict college students’ communication anxiety, but affinity humor style has better predictive power. This research held that relevance is the general principle of communicative cognition and has become a space of conceptual synthesis network. The combination of conceptual fusion and deviation theory with conventional theory can help us better understand verbal humor and reveal its cognitive basis. There is a close relationship between humorous language and human psychological mechanisms. Finally, there is also a clear relationship between different psychological mechanisms and the structure of humorous language.
