Embodiment in Virtual Reality and Augmented Reality Games: An Investigation on User Interface Haptic Controllers

Undoubtedly, virtual reality technologies stand out as one of the most rapidly expanding domains in the present era. Apart from features like clarity of vision, viewing angle and time distortion that are improving daily, user interfaces are another crucial part of this technology that is not talked about much but must be. This study investigates and summarizes the literature on wearable technology and haptic controllers, which serve as the player’s interface between virtual and augmented reality. The controllers and devices we investigate, try to achieve a holistic approach in the experience thus it appears to be a rich soil for future studies. Although many technological advancements and entirely new ones are anticipated, a thorough analysis of the phenomena of interaction, participation, and integration, as well as embodiment and presence, should shed light on the question of its scope, depth, assessment, and limitations.

El Niño phase transition by deforestation in the Maritime Continent

AbstractEl Niño-Southern Oscillation (ENSO), an irregular alternation between warm El Niño and cold La Niña phases, is the most prominent air-sea interaction phenomenon on Earth and greatly affects global weather and climate. Nevertheless, it remains unclear whether human activity can alter the characteristics of ENSO. We demonstrate, using reanalysis data and coupled general circulation models, that deforestation over the Maritime Continent (MC) favors a rapid transition of El Niño to La Niña. Deforestation over the MC can induce a regional enhancement in precipitation, which in turn leads to the strengthening of the easterly trade winds over the western equatorial Pacific owing to the Gill-response. These stronger trade winds, by inducing a shoaled thermocline in the eastern Pacific, are favorable for the development of cold sea surface temperature anomalies in the eastern equatorial Pacific during El Niño decaying years. Our results suggest that El Niño is more likely to be followed by La Niña if MC deforestation continues in the future.

Numerička analiza procesa penetracije pancirnog potkalibarnog projektila kalibra 30 mm

Introduction/purpose: In recent times, with the tendency to develop new types of armor-piercing ammunition, constant investments in the development of new types of armored obstacles is necessary. Obstacles made of high-alloy steel plates are still the best form of protection against larger caliber ammunition. There are a number of factors to consider when selecting an alloy, including the weight, dimensions, intended use, desired ballistic performance, and costs. According to that, a numerical analysis of penetration of a 30mm armor-piercing fin-stabilized discarding sabot projectile into the steel alloy Weldox 460 plates of different thicknesses at a distance of 1000m with a velocity of 1300m/s is presented in this paper. Methods: The stresses and deformations of the penetration effect were calculated through numerical analysis and finite element modeling. To specify material characteristics, the Johnson-Cook material model and the fracture of materials model have been utilized. In order to define models and carry out numerical calculations, the software packages FEMAP and LS Dyna have been used in this paper. Results: For a numerical analysis of the penetration process of this projectile type against armor obstacle, four different armor plate thicknesses are calculated: 10mm, 50mm, 100mm, and 110mm. For each of them, the results are shown in a form of stress and displacement, so that the interaction phenomena between the sub-projectile and the armor plate can be described. Conclusion: Modeling the impact on armor-piercing obstacles is extremely difficult, time-consuming, and complex, and the resulting models very successfully (or with some deviation) approximate the real problem of projectile penetration. One of the most effective methods for solving problems of this kind and others of a similar nature in recent times is the finite element method analysis. The material and the target dimensions, as well as the ballistic parameters and the material of the projectile have the biggest influence on projectile penetration. The target's resistance to penetration increases when all input parameters are maintained at the same level and its thickness is increased, and vice versa.

Hayek's extended mind: on the (im)possibility of Austrian behavioural economics

Abstract Recent work has argued for a Hayekian behavioural economics, which combines Austrian economics with behavioural economics as developed by Kahneman, Thaler, Sunstein, and others. We suggest that this hybrid is misguided because it relies on individual cognitivism. This view of cognition is incompatible with the Hayekian view of cognition which treats rationality as an emergent phenomenon of social interaction in an institutional environment. This Hayekian view, which we call epistemic institutionalism, is compatible with an alternative prominent perspective in psychology, that of the extended mind, sometimes known as 4E cognition. We demonstrate how the Hayekian perspective on individualism, the price system, and the evolution of rules can be connected to the extended mind programme, through concepts such as the coupling of the individual and their environment, cognitive off-loading, and affordances. We suggest that this alternative combination of Austrian economics and psychology provides a more fruitful way forward, especially because it foregrounds the processes of learning, error-correction, and institutional orders, rather than choice, bias, and individual rationality. To explain why Austrian economists have been receptive to behavioural economics, we distinguish epistemic institutionalism from the (radical) subjectivist approach, which shares key assumptions of individual cognitivism.

Aggregation and phase separation of α-synuclein in Parkinson's disease.

The deposition of α-synuclein (α-Syn) in Lewy bodies serves as a prominent pathological hallmark of Parkinson's disease (PD). Recent research has revealed that α-Syn can undergo liquid-liquid phase separation (LLPS) during its fibrillization. Over time, the maturation of the resulting condensates leads to a liquid-to-solid phase transition (LSPT) ultimately resulting in the amyloid deposition in cells which is linked to the pathogenesis and development of PD. Herein, we summarize the understanding of α-Syn aggregation which can be described by nucleation and elongation steps to obtain insights into the correlation of protein aggregation, structural polymorphism, and PD progression. Additionally, we discuss the LLPS phenomena of α-Syn and heterotypic cross-amyloid interactions with a focus on aberrant LSPT in the aggregation process. Exploring the underlying mechanisms and interplay between α-Syn aberrant aggregation, pathological phase transitions, and PD pathogenesis will shed light on potential therapeutic interventions.

Терминологическое измерение культурного капитала: грани взаимодействия

The issues of terminological measurement of cultural capital as an interdisciplinary phenomenon and aspects of such interaction are explored. The purpose of the study is to concretize the concept of cultural capital in the context of the terminological representation of this phenomenon, to identify the reasons for the diversity of definitions of the latter and ways to systematize approaches through theories of terminology; the influence of terminological activity on the growth (development) of cultural capital and its conversion into other types of capital (economic, social, symbolic, etc.). The authors indicate the structure of terminological activity, focusing on the specifics of the cultural factor for its implementation. It is demonstrated that identifying the cultural factor without taking into account the structure of terminological work is practically impossible, as well as the fact that culture manifests itself in this influence as a format such as capital. Terminology builds the following structure of its functioning by levels: linguistic, semantic, cognitive, communicative, sociocultural, etc. If a term is not represented at all designated basic levels, then it will not be fully used, and the cultural capital of its use will not be effective enough. It is proposed to systematize the variety of definitions of cultural capital through three directions: unification (standardization), pluralization (individualization), application as a separate case, which cannot be fit into the previous two directions. For each of the directions, the use of terminological theories is proposed: for unification - the general theory of terminology, for pluralization - the communicative theory of terminology, for a separate case - frame theory. The importance of the terminological dimension of cultural capital is so relevant that the authors propose to use the concept of “terminological capital”, on the one hand, as a component of cultural capital, on the other hand, as a way of growing cultural capital and a mechanism for converting it into other types of capital and vice versa. Using the example of the complex structure of terminological activity, the authors demonstrate that its use and implementation leads to the “doubling” of cultural worlds. If such growth of cultural worlds does not occur as a result of terminological activity, then such terminology is considered ineffective. Then it is not applied in principle, or waits for the moment when all other components of the latter are formed within the framework of the chosen culture and become terminological capital.

Vocal music curriculum design and teaching quality evaluation in colleges and universities based on interactive structure model

Abstract Aiming at the current phenomenon of low teacher-student interaction in vocal music teaching, this paper combines the interaction structure model for the innovation and practice of college vocal music courses. Then, this paper uses Euclidean distance to improve the binary tree SVM multi-class classification algorithm, calculates the distance between the teaching samples of each vocal music course, classifies the samples for processing, and obtains the DBT-SVM multi-class classification algorithm. Finally, the DBT-SVM algorithm was used to establish an evaluation model for vocal course teaching quality in colleges and universities to assess the quality of vocal course teaching models. Each three-level index of teaching motivationality has an evaluation score above 80, which is a good level. The evaluation score for the pedagogical index is 89.44, which is almost excellent. The average score of the second-level index of interpersonal interaction is 74.52, which needs to be further improved. The teaching model of the college vocal music course proposed in this paper lays the foundation for the interactive transformation of vocal music teaching and provides a reference model for the improvement of the learning effect of college students’ vocal music courses.

A novel model of nonlocal photoacoustic and plasmaelastic heated by laser pulsed excitation of nanoscale semiconductor medium

The study takes into account the diffusion of photo-excited carriers in the presence of a laser pulse and theoretically investigates photoacoustic wave propagation in the thermoelastic domain. In a nonlocality medium, the phenomena of thermomechanical and acoustic wave interaction are considered. Thermoelasticity, photothermal, and photoacoustic theories provide the controlling formulas. Photoacoustic waves are not dependent on electron–phonon or electron–hole thermalization processes; rather, they are produced by thermoelastic stress resulting from the temperature increase induced by the laser. The optical, elastic, and thermoelastic characteristics of nanoscale semiconductor materials are taken into account and photoacoustic signals are predicted by solving a thermal diffusion issue and a thermoelastic problem in combination. The mathematical model can be solved using the harmonic wave approach. By obtaining numerical solutions, all the physical fields of the physical domain, such as thermal, acoustic, mechanical, and carrier density diffusion, as well as displacements and temperatures, can be derived. The influences of nonlocal parameters, thermal delay, and laser pulse effect are investigated and compared using two- and three-dimensional visual representations, corresponding to two-dimensions and three-dimensions domains, respectively.

Exploring the Change of Literary Narrative and Reader Interaction Mode in the New Media Environment

Abstract Literature in the new media environment breaks the boundaries of the industry and reflects the Internet thinking of openness, sharing, and interaction. Starting from the study of interactive narrative phenomena in digital media art, this paper systematically explores the narrative style and characteristics of digital media art. X literary reading platform is selected as a representative, and through correlation analysis and regression analysis, the relationship between the reader interaction of the platform users, the readers’ perceived platform availability, and the readers’ perceived social interaction is explored. The study found that 0.2215 of the reader interactions in the reader interaction patterns of Platform X were social interactions, which are a type of social interaction mediated by the network, and that reader interaction had a significant positive effect on readers’ perceived platform availability and social interactions. The contribution of the study lies in the measurement of readers’ perceived social interaction through the definition of social interaction, while the mediating mechanism of platform availability reveals how readers perceive social interaction in their interactions with online literature. To enhance user services and narrative art changes in the online publishing of literary works, it is crucial to enhance the social interactions that readers of online literature perceive during the reading process.

Numerical and analytical models of the mechanism of torque and axial load transmission in a shock absorber for drilling oil, gas and geothermal wells

The paper proposes an improved design of a shock absorber used in drilling deep oil and gas and geothermal wells with polycrystalline diamond compact (PDC) bits. The proposed innovations successfully combat the dangerous phenomenon of self-excited vibrations, which can lead to malfunctions such as stick-slip and whirling of the drilling tool. Most conventional drill shock absorbers are designed to only absorb longitudinal vibrations, which was sufficient when using roller cutter bits for the drilling process. However, the design features of PDC bits and the phenomenon of interaction of their cutters with interlayered rocks during deep drilling impose new requirements on the properties of the drill shock absorber. To protect the downhole tool from abnormal torque values and torque oscillations, it is proposed to equip the shock absorber with a special torque transmission unit in the form of a fourteen-thread self-releasing screw pair. This unit is capable of transforming increases in external torque into increases in the force that loads the elastic element of the shock absorber. The numerical and analytical models of the mechanism of transferring external axial load and torque to the elastic element of the drill shock absorber are constructed. The distribution of contact pressures on the interacting surfaces of the screw pair and the distribution of equivalent stresses in the screw pair parts are analysed. The strength of the proposed drill shock absorber assembly was evaluated using the Huber-von Mises energy criterion. The dependence of the load transmitted to the elastic element of the shock absorber on changes in the external torque and external axial force is investigated. In general, it is determined that the external load is distributed evenly between all turns of the screw pair, and the limit state of the parts of the proposed assembly is not reached even under high-torque operating load. The obtained analytical dependencies will allow to effectively determine the required strength and stiffness of the elastic element of the drill shock absorber at the design stage. The obtained analytical results were verified using a finite element model.

NOVEL INVESTIGATION OF FRACTIONAL LONG- AND SHORT-WAVE INTERACTION SYSTEM

In ocean engineering, the long- and short-wave interaction system represents a crucial nonlinear evolution equation that elucidates the resonant interaction phenomenon between ocean waves. In this study, we describe the fractional long and short-wave interaction (FLSWI) system employing the M-truncated derivative. Subsequently, we employ the extended fractional [Formula: see text] and the fractional [Formula: see text] methods to address the FLSWI system. These two approaches yields novel and intriguing soliton solutions. To further elucidate the derived soliton solutions, three-dimensional visualizations are constructed and analyzed.

Lessons from international case studies on bridge-slide interaction problems

Bridges and viaducts are facing progressive and natural degradation of materials, structural elements, and the of territory in which the works are located. The deterioration is exacerbated by increasingly frequent and abrupt “accelerations”, caused by natural hazard events such as landslides and floods, which are intensified by climate change. In particular, landslide events exhibit a range of interaction phenomena, from simple quasi-static forces for slow landslides, to dynamic forces generated by impact events. This research work presents a collection of international case studies of bridge-landslide interactions that have resulted in structure damage or collapse. Relevant variables from these cases were rationalized to allow statistical analysis in aggregate form considering different interaction mechanisms. The results show that the type of landslide, its velocity, volume, elements involved, and direction of movement with respect to the direction of the bridge are some of the main parameters. This approach provides valuable guidance for implementing more refined landslide risk characterization models for bridges.

The Value of Financial Planning—A Theoretically-Grounded Approach

This paper lays a foundation for quantifying the interaction “value” effects of the financial planner/client relationship through the lens of Financial Planning Client Interaction Theory (FPCIT), utilizing integration—a mathematical process commonly used in calculus to find the area under a curve. FPCIT recently emerged in response to practitioner and researcher calls for theory specific to the financial planning profession. FPCIT posits that the distinction of the professional practice of financial planning and its value to consumers is centered upon the unique and complex human interaction phenomenon inherent in the client relationship. FPCIT extends the value of financial planning discussion by offering a theory-based vantage point from which the profession can analyze the origins and synthesis of value within financial planning practice. The implications of FPCIT and the valuation method presented in this paper underscore the relevance of financial therapy, counseling, and psychology in expanding the financial planner’s skillset beyond technical expertise.

Ad-hoc-compounds in spoken German

Abstract Occasionalisms, i.e., non-lexicalized ad-hoc-expressions that are coined for a specific occasion, are a recurrent phenomenon in verbal interactions. Even though recipients have not heard those novel word formations before, they can still understand them. This paper reports on a study from an Interactional Linguistics perspective which explores ad-hoc-expressions in spoken German, such as streichelmichbärchenpärchen (‘stroke-me-little-bear-couple’) and windeldroge (‘diaper-drug’). It draws on an analysis of 934 ad-hoc-compounds in a corpus of German interaction. These typically do not cause a problem of understanding, because their meaning is inferable due to different resources that help recipients understand unfamiliar expressions: a specific word formation with a high degree of compositionality, cues or anchoring in the prior context or common ground. While a compositional word formation is not always necessary to sufficiently understand meaning in interaction due to other resources, opaque word formation has its limits when it comes to understanding the meaning of an expression especially when recipients cannot rely on other resources to understand the expression.

Friction behavior of 30CrNi2MoVA gun barrel steel after thermo-cyclic treatment: Air and simulated seawater

The influence of gun barrel erosion has been proposed, but the research on the wear behavior of gun steel during the initial extrusion phase remains limited. This study employed an experimental approach to investigate the wear of 30CrNi2MoVA gun steel after untreated (25 °C) and thermal cycling treatments (400 °C and 800 °C) under both air and simulated seawater environments. In the air environment, abrasive wear and adhesive wear mechanisms were prominently observed. In the simulated seawater, abrasive wear mechanism was predominant. In both environments, the surface morphology and wear profiles of the untreated samples were similar, exhibiting a negative interaction phenomenon. After thermal cycling treatment, the corrosion wear resistance of 30CrNi2MoVA steel were significantly reduced. Among them, the material performance is the lowest at 800 °C. Therefore, this study provides theoretical and experimental evidence for improving the friction and wear performance of gun barrel rifling during the bullet extrusion process.

Dynamic testing and modeling of span interaction in high-speed railway girder bridges

This paper presents the results of an extensive experimental campaign conducted on high-speed railway girder bridges along the Rome-Florence railway line. The campaign includes material characterization and in-situ dynamic tests, incorporating vibration signals from both ambient-induced activities and train passages. The study focuses on the modeling and simulation procedures necessary for analyzing existing railway girder bridges, considering the dynamic interaction between adjacent simple supported spans. The degree of coupling caused by railroad equipment can lead to interaction phenomena, such as vibrations corresponding to mode shapes encompassing multiple spans, observed along the bridge. A multilevel modeling strategy is proposed, starting with a single span to identify the most accurate and computationally efficient approaches (frame-based, shell-based, or mixed). Subsequently, full-scale and reduced-order models of the entire structures are developed, considering the connections between rails, superstructure, and piers, to study the interaction between adjacent spans. Three case studies are presented to demonstrate the general validity of the proposed approaches, comparing the numerical results with experimental outcomes obtained from the in-situ tests.

The strengthened role of new predictors of Indian Ocean Dipole (IOD) during the recent decades of weakened ENSO-IOD relationship

Indian Ocean Dipole (IOD) is the major interannual ocean-atmosphere interaction phenomena in the Indian Ocean (IO) and is influenced by external forcing such as El Nino Southern Oscillation (ENSO). Meanwhile, its co-occurrence and stronger relationship with ENSO have decreased during recent decades. The IOD variability also reduced after 2000, accompanied by a shift of the western pole to central IO extending further southward. The study reports that the boreal fall (SON, September, October, November) season IOD has an intensified relationship with the previous winter Subtropical Indian Ocean dipole (SIOD) and spring season equatorial north tropical Atlantic (NTA) SST anomalies., while the ENSO relationship is reduced from its pre-2000 value. It is found that the persistent warming (cooling) in the western side of positive (negative) SIOD during the previous winter induces easterly (westerly) wind anomalies in the equatorial IO during the following summer and fall, leading to positive (negative) IOD events. These IOD events have the western pole shifted to south-central IO instead of the canonical northwestern warming. The spring season NTA SST anomalies induce stronger summer season circulation and SST gradient in the equatorial Pacific, like ENSO. During the SON season, this pattern is associated with cooling and easterly wind anomalies in the tropical eastern IO and IOD. These two patterns explain the major mode of IOD variability after 2000. While the IOD associated with NTA have co-occurring ENSO during summer and fall, the SIOD-induced IOD events are independent of ENSO in the Pacific. Thus, these two predictors provide long-lead predictability (2–3 seasons ahead) of IOD for both ENSO co-occurring and non-ENSO IOD events. However, the IOD predictability of seasonal prediction models mainly depends on the ENSO-IOD relationship, resulting in reduced IOD skills for many of them after 2000. The models such as COLA-CCSM4, which has improved skill have stronger than observed ENSO-IOD relationship than the pre-2000 period. A linear regression model including SIOD and NTA SST indices of the previous winter and spring season respectively as predictors simulates IOD with a skill of around 0.65 during the recent period, indicating the necessity of seasonal prediction models to capture the variability in the southern IO and NTA and their teleconnections for better prediction of IOD in the recent period of reduced ENSO skill.

A Mixed Methods Approach to Analyzing Embodied Interaction: The Potentials of Integrated Mixed Methods Analysis of Video Interaction Data

Video has become a widespread tool for capturing naturalistic behavioral data. While mixed methods show great potential in understanding the active nature of children’s interaction, only a few studies have developed mixed methods for video-based interaction research. This paper presents a mixed methods embodied interaction model appropriate for studying complex embodied interaction and draws on methodological insights from a mixed methods project to capture changes in children’s interaction with touchscreen technologies. The paper details how integrated mixed methods analysis was needed to fully explain the results and how mono-method studies would provide misleading results. The theoretical advancements generated during the project illustrate how mixed methods for video-based studies have valuable properties for understanding complex interactional phenomena, such as learning.

Study of Soliton Interaction in Optical Fibers with Third Order Dispersion and Higher Order Nonlinear Effects

In this paper, we present a numerical approach to solve the GNLSE and analyze soliton interaction phenomena using COMSOL environment. By leveraging the capabilities of COMSOL's PDE module, we can accurately capture the dynamics of solitons and investigate their interactions. We analyze the impact of different parameters such as soliton power, initial separation distance, and dispersion characteristics on the soliton dynamics. Furthermore, we examine the role of higher-order dispersion terms in shaping the soliton interactions. Our findings demonstrate the effectiveness of the proposed numerical approach in accurately simulating and analyzing soliton interaction phenomena. The COMSOL-based methodology provides a flexible and efficient framework for studying complex nonlinear optical systems, enabling researchers to gain insights into the behavior of solitons in different media and design optimized communication systems. This paper contributes to the understanding of soliton dynamics and provides a practical tool for investigating the behavior of solitons in nonlinear dispersive media. The presented numerical approach using COMSOL opens avenues for further research in nonlinear optics and fiber optic communication systems.
