description: Many mobile phone usage behaviors and cognitions have become habitual, and many people have developed a strong connectedness to their mobile phones and the internet. Yet, habitualized mobile phone connectedness might evoke stress and counter long-term goals. Mindfulness has shown promise in counteracting destructive (mobile phone) habits. Over the course of three preregistered studies, we investigated the interrelations between mindfulness, four dimensions of mobile phone connectedness, and stress. Our results indicate that more mindful individuals check their mobile phones less automatically, perform less multitasking, have a lower mobile phone attachment, and experience less online vigilance. Self-control is an important mediator in these relationships. Further, mindful individuals experience less stress; however, mobile phone behaviors and cognitions do not mediate this relationship. Moreover, mindfulness-based stress reduction training or mediation apps seem to be powerful tools for cultivating mindfulness, as they promoted an increase in mindfulness and a decrease in the investigated dimensions of mobile phone connectedness and stress. Results are discussed regarding implications for research and practice.

description: The issue of immigrants' children social integration in educational and social environment of developed west countries as well as equal opportunity conditions in hosting countries, have constituted subject of scientific analysis and relevant discussions for a long time. Through the adoption of a psychosocial approach regarding the formation of the social identity of a developing person in a multicultural environment, we attempted to explore as many aspects of the group of students’ social representations as possible, in a purely Greek school of the Greek community in Munich. Through a discourse analysis, actions and interactions within an ethnographic study, we investigated: i) the attitudes and their representations in the context of their eth-no-cultural group of reference, ii) the possible existence of ethnic stereotypes of their native or foreigner peers, as well as iii) the experiences which relate to issues of social inclusion and exclusion. The results of this research highlight the existence of a variety of stereotypes, which are significantly connected to attempts of inclusion of students both at school and within the wider social environment. Let it be noted that this case study also contributes to the reinforcement of some theoretical approaches on these issues, but also to the emergence of the necessity of making compensatory/therapeutic educational interventions in educational conditions in such multicultural environments.

description: We study the arithmetic (geometric) progressions in the $x$-coordinates of quadratic points on smooth projective planar curves defined over a number field $k$. Unless the curve is hyperelliptic, we prove that these progressions must be finite. We, moreover, show that the arithmetic gonality of the curve determines the infinitude of these progressions in the set of $\overline{k}$-points with field of definition of degree at most $n$, $n\ge 3$.
Asymptotic laws for tagged-particle motion in glassy systems

description: Within the mode-coupling theory for structural relaxation in simple systems the asymptotic laws and their leading-asymptotic correction formulas are derived for the motion of a tagged particle near a glass-transition singularity. These analytic results are compared with numerical ones of the equations of motion evaluated for a tagged hard sphere moving in a hard-sphere system. It is found that the long-time part of the two-step relaxation process for the mean-squared displacement can be characterized by the $α$-relaxation-scaling law and von Schweidler's power-law decay while the critical-decay regime is dominated by the corrections to the leading power-law behavior. For parameters of interest for the interpretations of experimental data, the corrections to the leading asymptotic laws for the non-Gaussian parameter are found to be so large that the leading asymptotic results are altered qualitatively by the corrections. Results for the non-Gaussian parameter are shown to follow qualitatively the findings reported in the molecular-dynamics-simulations work by Kob and Andersen [Phys. Rev. E 51, 4626 (1995)].
VNI-3.1: MC-simulation program to study high-energy particle collisions in QCD by space-time evolution of parton-cascades and parton-hadron conversion

description: VNI is a general-purpose Monte-Carlo event-generator, which includes the simulation of lepton-lepton, lepton-hadron, lepton-nucleus, hadron-hadron, hadron-nucleus, and nucleus-nucleus collisions. On the basis of renormalization-group improved parton description and quantum-kinetic theory, it uses the real-time evolution of parton cascades in conjunction with a self-consistent hadronization scheme that is governed by the dynamics itself. The causal evolution from a specific initial state (determined by the colliding beam particles) is followed by the time-development of the phase-space densities of partons, pre-hadronic parton clusters, and final-state hadrons, in position-space, momentum-space and color-space. The parton-evolution is described in terms of a space-time generalization of the familiar momentum-space description of multipl (semi) hard interactions in QCD, involving 2 -> 2 parton collisions, 2 -> 1 parton fusion processes, and 1 -> 2 radiation processes. The formation of color-singlet pre-hadronic clusters and their decays into hadrons, on the other hand, is treated by using a spatial criterion motivated by confinement and a non-perturbative model for hadronization. This article gives a brief review of the physics underlying VNI, which is followed by a detailed description of the program itself. The latter program description emphasizes easy-to-use pragmatism and explains how to use the program (including a simple example), annotates input and control parameters, and discusses output data provided by it.

description: Early identification and intervention for children experiencing difficulties in learning provides a foundation for later learning and could thereby foster later academic success experiences for children at risk. The purpose of this study is to present an instrument assessing pre-school teachers’ readiness to identify children at risk of developing Specific Learning Disabilities in the future. Two pilot studies were conducted in order to test the instrument. Fifty students and teachers and twenty-two students participated in those studies respectively. The results show that the research instrument is generally a reliable instrument. The difficulties in design and the positive and negative aspects of the instrument are thoroughly discussed.

description: We explored new antecedents and consequences of identification with media characters that are related to concreteness or abstractness of representations. First, we examined how the portrayal of the protagonist’s behavior affects the reader’s identification with her. Participants read one of four narratives in which we manipulated the character’s usual behavior (abstract traits) and her behavior on a specific bad day (concrete states). As expected, when the character had positive traits but behaved unkindly in the negative situation, compared to the other conditions, the readers (N = 206) identified more strongly with her through the mediation of higher situational attributions, i.e. attributing the protagonist’s behavior more to the situation than to her traits. Then we examined the effect of identification on the readers’ concrete and abstract thoughts. We hypothesized and found that stronger identification with the character was related to increasingly more concrete thinking about the protagonist’s specific plans and reactions regarding the situation than abstract thinking about the protagonist’s life in general. Additionally, stronger identification was associated with more concrete thoughts about the readers themselves through the partial mediation of concrete thoughts about the character. These findings may reconcile previous inconsistent results about identification and have implications for narrative persuasion.
A Theoretical Framework for AGI Based on the Synergistic  Operation of Multiple Modules-From human,To the infinite
Creators: name: Yan, Kailin
Publisher: name: Zenodo
Year: 2025

description: In recent years, the emergence of large language models (LLMs) has greatly advanced AGI research, revealing their potential for tasks ranging from natural language understanding to complex reasoning. This paper presents a theoretical framework for LLM-based knowledge-injection neural networks, achieving comprehensive AGI functionality through the collaborative interaction of seven modules: the Perception Module (based on few-shot learning and change-driven sensory entropy), the Logical Reasoning Module (supporting natural language logical mapping and dynamic decision-making), the Autonomous Consciousness Module (based on Bayesian generalization and behavioral reflection), the Metric Module (dynamically assessing commonalities and differences), the Memory/Knowledge Module (storing unique memories and experiences while integrating LLM with internet-based learning), the Emotion Module (constructing emotions and values through hormone-driven mechanisms), and the Physical Environment Simulation Module (modeling environmental sequences and conducting virtual experiments). Bidirectional LLM mapping facilitates communication between modules, and all modules incorporate internet-based self-learning to handle new tasks. Key innovations include natural language-based logical reasoning, hormone-driven desire mechanisms, dynamic metric functions for common feature extraction, change-driven perception prioritization, consequence prediction through sensory sequences, cognitive leaps triggered by free will, adaptive self-learning through the internet, and modular design prospects. Through detailed theoretical elaboration and interdisciplinary perspectives, this work provides a comprehensive foundation for constructing a complete AGI entity.

description: The aim of this study is the recording of student’s postures and the highlighting of the importance of nonverbal messages, which are transmitted through this, for the teacher. The results the survey revealed that the dominant body position of students transmits messages that can function as feedback for the organization of teaching process and the pedagogic communication. The student’s posture is affected by the size of couches, the layout of the classroom, the long immobility and the possible incomplete education for the proper posture. The mobility of students observed its downward trend as their age increased. In conclusion, it is assumed that the attitude of the student’s posture, as a form of nonverbal communication and as part of good health, may affect the achievement of learning outcomes.

description: The problem of inverse statistics (statistics of distances for which the signal fluctuations are larger than a certain threshold) in differentiable signals with power law spectrum, $E(k) \sim k^{-α}$, $3 \le α< 5$, is discussed. We show that for these signals, with random phases, exit-distance moments follow a bi-fractal distribution. We also investigate two dimensional turbulent flows in the direct cascade regime, which display a more complex behavior. We give numerical evidences that the inverse statistics of 2d turbulent flows is described by a multi-fractal probability distribution, i.e. the statistics of laminar events is not simply captured by the exponent $α$ characterizing the spectrum.

description: Nowadays, the teachers’ training in Information and Communication Technologies (ICT) considered important and, more, essential. The benefits of distance education receive, primarily, teachers in remote and inaccessible areas, who are unable to attend live training programs, either due to the limitation of space or time. This paper refers to Primary and Secondary teachers’ Training in remote areas of Greece, with the contribution of a distance education model, under the Project “Foreign and repatriated students' education”. The results of the quantitative research highlight the importance of education through electronic platform and referred to the fulfilment of a large part of the participants' expectations. Qualitative analyzes, of short answer questions, present the recommendations of teachers to improve the already existed online and distance learning models.

description: The recent emergence of strain gradient engineering directly affects the nanomechanics, optoelectronics and thermal transport fields in 2D materials. More specifically, large suspended graphene under very high stress represents the quintessence for nanomechanical mass detection through unique molecular reactions. Different techniques have been used to induce strain in 2D materials, for instance by applying tip indentation, pressure or substrate bending on a graphene membrane. Nevertheless, an efficient way to control the strain of a structure is to engineer the system geometry as shown in everyday life in architecture and acoustics. Similarly, we studied the concentration of strain in artificial nanoconstrictions (~100 nm) in a suspended epitaxial bilayer graphene membrane with different geometries and lengths ranging from 10 to 40 micrometer. We carefully isolated the strain signature from micro-Raman measurements and extracted information on a scale below the laser spot size by analyzing the broadened shape of our Raman peaks, up to 100 cm-1. We potentially measured a strong strain concentration in a nanoconstriction up to 5percent, which is 20 times larger than the native epitaxial graphene strain. Moreover, with a bilayer graphene, our configuration naturally enhanced the native asymmetric strain between the upper and lower graphene layers. In contrast to previous results, we can achieve any kind of complex strain tensor in graphene thanks to our structural approach. This method completes the previous strain-induced techniques and opens up new perspectives for bilayer graphene and 2D heterostructures based devices.
Quasiparticle Spectrum of d-wave Superconductors in the Mixed State

description: The quasiparticle spectrum of a two-dimensional d-wave superconductor in the mixed state, H_{c1} << H << H_{c2}, is studied both analytically and numerically using the linearized Bogoliubov-de Gennes equation. We consider various values of the "anisotropy ratio" v_F/v_Delta for the quasiparticle velocities at the Dirac points, and we examine the implications of symmetry. For a Bravais lattice of vortices, we find there is always an isolated energy-zero (Dirac point) at the center of the Brillouin zone, but for a non-Bravais lattice with two vortices per unit cell there is generally an energy gap. In both of these cases, the density of states should vanish at zero energy, in contrast with the semiclassical prediction of a constant density of states, though the latter may hold down to very low energies for large anisotropy ratios. This result is closely related to the particle-hole symmetry of the band structures in lattices with two vortices per unit cell. More complicated non-Bravais vortex lattice configurations with at least four vortices per unit cell can break the particle-hole symmetry of the linearized energy spectrum and lead to a finite density of states at zero energy.

description: In a recent work on direction-of-arrival (DOA) estimation of multiple speakers with convolutional neural networks (CNNs), the phase component of short-time Fourier transform (STFT) coefficients of the microphone signal is given as input and small filters are used to learn the phase relations between neighboring microphones. Due to this chosen filter size, $M-1$ convolution layers are required to achieve the best performance for a microphone array with M microphones. For arrays with large number of microphones, this requirement leads to a high computational cost making the method practically infeasible. In this work, we propose to use systematic dilations of the convolution filters in each of the convolution layers of the previously proposed CNN for expansion of the receptive field of the filters to reduce the computational cost of the method. Different strategies for expansion of the receptive field of the filters for a specific microphone array are explored. With experimental analysis of the different strategies, it is shown that an aggressive expansion strategy results in a considerable reduction in computational cost while a relatively gradual expansion of the receptive field exhibits the best DOA estimation performance along with reduction in the computational cost.

description: The optical conductivity sigma (omega) of undoped YBa2Cu3O6 is studied in detail in the mid-infrared range. Substitutions on all but the Ba site are used to identify the prominent absorption processes at 2800 and 3800 cm^-1. Experimental evidence for bimagnon-plus-phonon absorption is collected. A more critical analysis of the lineshape and the spectral weight reveals the limits of this approach. Although phonon-2-magnon multiple scattering seems to reproduce the lineshape, the necessary coupling is unrealistically large. The strong increase of high frequency spectral weight with increasing temperature makes the failure of spin-wave theory even more evident.

description: In this paper, we propose a network-optimization framework for the analysis of multi-agent systems with passive-short agents. We consider the known connection between diffusively-coupled maximally equilibrium-independent passive systems, and network optimization, culminating in a pair of dual convex network optimization problems, whose minimizers are exactly the steady-states of the closed-loop system. We propose a network-based regularization term to the network optimization problem and show that it results in a network-based feedback using only relative outputs. We prove that if the average of the passivity indices is positive, then we convexify the problem, passivize the agents, and that steady-states of the augmented system correspond to the minimizers of the regularized network optimization problem. We also suggest a hybrid approach, in which only a subset of agents sense their own output, and show that if the set is nonempty, then we can always achieve the same correspondence as above, regardless of the passivity indices. We demonstrate our results on a traffic model with non-passive agents and limited GNSS reception.

description: Low-oxygen settings and transition zones between strictly anoxic and oxic conditions may have characterised large expanses of Precambrian continental margins, where oxygen-breathing, complex life emerged and diversified. Accurate reconstructions of oxygen levels in such conditions are therefore required, but current geochemical proxies fail in identifying transitional redox conditions. Uranium isotopes are an emerging palaeoredox proxy, as large isotope fractionations are recorded during the reduction of uranium into anoxic sediments. Their potential application to transitional conditions is, however, unclear, because the redox regulating mineralogy of such environments and the associated isotope fractionations are poorly constrained. Here, we explore the mineralogical transformations occurring during the partial oxidation of mackinawite. We show that green rust, a key mineral of Precambrian oceans, forms as a by-product of mackinawite oxidation, along with uraninite and polysulphide. We also demonstrate that this mechanism records a large abiotic uranium isotope fractionation during its reaction with aqueous iron sulphide.

description: Rare de novo heterozygous loss-of-function SETBP1 variants lead to a neurodevelopmental disorder characterized by speech deficits, indicating a potential involvement of SETBP1 in human speech. However, the expression pattern of SETBP1 in brain regions associated with vocal learning remains poorly understood, along with the underlying molecular mechanisms linking it to vocal production. In this study, we examined SETBP1 expression in the brain of male zebra finches, a well-established model for studying vocal production learning. We demonstrated that zebra finch SETBP1 exhibits a greater number of exons and isoforms compared to its human counterpart. We characterized a SETBP1 antibody and showed that SETBP1 colocalized with FoxP1, FoxP2, and Parvalbumin in key song nuclei. Moreover, SETBP1 expression in neurons in Area X is significantly higher in zebra finches singing alone, than those singing courtship song to a female, or non-singers. Importantly, we found a distinctive neuronal protein expression of SETBP1 and FoxP2 in Area X only in zebra finches singing alone, but not in the other conditions. We demonstrated SETBP1´s regulatory role on FoxP2 promoter activity in vitro. Taken together, these findings provide compelling evidence for SETBP1 expression in brain regions to be crucial for vocal learning and its modulation by singing behavior.

description: Computing conceptual structures, like formal concept lattices, is in the age of massive data sets a challenging task. There are various approaches to deal with this, e.g., random sampling, parallelization, or attribute extraction. A so far not investigated method in the realm of formal concept analysis is attribute selection, as done in machine learning. Building up on this we introduce a method for attribute selection in formal contexts. To this end, we propose the notion of relevant attributes which enables us to define a relative relevance function, reflecting both the order structure of the concept lattice as well as distribution of objects on it. Finally, we overcome computational challenges for computing the relative relevance through an approximation approach based on information entropy.

description: This study is a contribution to the Pedagogical Content Knowledge (PCK) concerning the “objects and materials” section of the Greek science curriculum for early childhood education. It approaches the PCK of the aforementioned section from a theoretical and a practical perspective via an application of constructive activities. The research took place at a Salonica kindergarten and it consisted of 10 (45- minutes) weekly sessions in which 25 pupils of average age 5.1 years participated. The identification of their representations concerning materials was accompanied by a teaching proposal, which was completed through creative activities. Special emphasis was placed on the pupils’ conceptual transition from objects and their characteristics to materials and their properties. The connection of the properties of materials with the use of objects helped pupils obtain a deeper and more substantive under standing of the material world and be creatively engaged in transformations of materials and objects in a playful and joyful classroom environment.

description: The properties of a fictitious, fermionic, many-body system based on the complex zeros of the Riemann zeta function are studied. The imaginary part of the zeros are interpreted as mean-field single-particle energies, and one fills them up to a Fermi energy $E_F$. The distribution of the total energy is shown to be non-Gaussian, asymmetric, and independent of $E_F$ in the limit $E_F\to\infty$. The moments of the limit distribution are computed analytically. The autocorrelation function, the finite energy corrections, and a comparison with random matrix theory are also discussed.

description: We prove results on moments of $L$-functions in the function field setting, where the moment averages are taken over primitive characters of modulus $R$, where $R$ is a polynomial in $\mathbb{F}_q [T]$. We consider the behaviour as $\textrm{deg} R \rightarrow \infty$ and the cardinality of the finite field is fixed. Specifically, we obtain an exact formula for the second moment provided that $R$ is square-full, and an asymptotic formula for the fourth moment for any $R$. The fourth moment result is a function field analogue of Heath-Brown's result in the number field setting, which was subsequently improved by Soundararajan. Both the second and fourth moment results extend work done by Tamam in the function field setting who focused on the case where $R$ is prime.

description: This study applies Monte Carlo simulations to assess the impact of market uncertainty on investment portfolios from 2020 to 2024. The objective is to evaluate the effectiveness of Monte Carlo methods in modeling financial volatility, analyze investment strategy sensitivity to market fluctuations, and identify key factors influencing portfolio performance. A quantitative research approach was employed, utilizing historical market data from Bloomberg and Reuters. The study generated 10,000 simulations under varying economic conditions, incorporating asset returns, volatility, and correlation factors. Key findings indicate that high market volatility significantly increases risk exposure, with a standard deviation of 15% compared to 3% in stable conditions. Regression analysis revealed a strong negative correlation (r ≈ -0.87, p < 0.05) between inflation and portfolio returns, confirming that inflation is a critical determinant of investment performance. The optimal asset allocation strategy was found to be a 50% stock and 50% bond portfolio, yielding the highest Sharpe ratio of 0.42. The study concludes that Monte Carlo simulations provide a robust framework for forecasting investment risk under uncertain market conditions. It recommends integrating behavioral finance insights and macroeconomic variables into financial models, adopting diversified risk management approaches, and leveraging high-performance computing for more accurate simulations. These findings offer practical implications for investors and policymakers in optimizing portfolio strategies amid financial uncertainty.

description: Literature course provides a context for teaching approaches that go beyond a technical rationalism, which aims at a prescribed desirable result. In congruence with this belief, two teachers of philology developed an innovative teaching intervention in two classes of mixed learning ability. Students created and played though drama their own meta-text, which refers to personal and social issues concerning their own lives. This event redefined their attitudes toward the teaching-learning process and had fruitful pedagogical consequences, especially with regard to procedures of students’ differentiated learning and teachers’ reflection. In this article is presented the method of the research approach that was implemented, as well as the results and conclusions of the intervention.
