Oxygen Functional Groups Regulate Cobalt-Porphyrin Molecular Electrocatalyst for Acidic H2O2 Electrosynthesis at Industrial-Level Current.

Electrosynthesis of hydrogen peroxide (H2O2) based on proton exchange membrane (PEM) reactor represents a promising approach to industrial-level H2O2 production, while it is hampered by the lack of high-efficiency electrocatalysts in acidic medium. Herein, we present a strategy for the specific oxygen functional group (OFG) regulation to promote the H2O2 selectivity up to 92 % in acid on cobalt-porphyrin molecular assembled with reduced graphene oxide. In situ X-ray adsorption spectroscopy, in situ Raman spectroscopy and Kelvin probe force microscopy combined with theoretical calculation unravel that different OFGs exert distinctive regulation effects on the electronic structure of Co center through either remote (carboxyl and epoxy) or vicinal (hydroxyl) interaction manners, thus leading to the opposite influences on the promotion in 2e- ORR selectivity. As a consequence, the PEM electrolyzer integrated with the optimized catalyst can continuously and stably produce the high-concentration of ca. 7 wt % pure H2O2 aqueous solution at 400 mA cm-2 over 200 h with a cell voltage as low as ca. 2.1 V, suggesting the application potential in industrial-scale H2O2 electrosynthesis.

Isolation Journal: Remote Interactions in the Time of the COVID-19 Pandemic

ABSTRACT This paper discusses the development of artistic collaboration during the global lockdown, related to the COVID-19 pandemic. The art work under study involves the author’s practices of ecological sound art and intercultural collaboration in collaboration with Canadian composer and improviser John Oliver. A primary outcome of this work was the album Isolation Journal, released in 2020, in the midst of the pandemic. One feature of Isolation Journal was how it revisited site-specific recordings made in Vietnam, on the countryside north of Hanoi, for an installation made by Östersjö in collaboration with Nguyễn Thanh Thủy and Matthew Sansom [Östersjö, Stefan, and Thanh Thủy Nguyễn. 2016. “The Sounds of Hanoi and the After-Image of the Homeland.” Journal of Sonic Studies 12. https://www.researchcatalogue.net/view/246523/246546]. Through remote interactions, and by building a complex sampler instrument using Östersjö's recordings of Aeolian đàn đáy, a traditional Vietnamese lute, as well as field recordings from the site, Oliver and Östersjö created the album Isolation Journal through remote interaction. This in turn became a fundamental building block when the author's Vietnamese/Swedish group The Six Tones took the initiative to develop a scene for telematic performance at Manzi Art Space in Hanoi. This series started out with a concert with John Oliver, The Six Tones and guest performers from Hanoi in July 2020. Building on audio and video documentation, as well as on qualitative interviews with the participating co-performers, an analysis of the emergence of discursive voice [Gorton, David, and Stefan Östersjö. 2019. “Austerity Measures I: Performing the Discursive Voice.” In Voices, Bodies, Practices: Performing Musical Subjectivities, edited by Catherine Laws, William Brooks, David Gorton, Nguyễn Thanh Thủy, Stefan Östersjö, and Jeremy J. Wells, 29–79. Orpheus Institute Series. Leuven: Leuven University Press] is drawn from these two internally linked artistic projects. The paper develops the analytical framework of tele-copresence, a synthesis of the contrasting concepts of telepresence and copresence, as a means for analysing the virtual presence which emerges through such remote musical interaction.

CURRENT PROBLEMS OF COUNTERING ADMINISTRATIVE OFFENSE COMPLETED USING INFORMATION TECHNOLOGY

The processes of informatization and digitalization are intensified in many spheres of life of Russian society and the state, which, in addition to the positive impact, creates significant threats of the spread of illegal practices associated with the use of modern information and digital technologies. Despite the fact that the legal regulation of information legal relations in the Russian Federation is currently receiving close attention, the popularity of mobile communications, the Internet and other technologies for remote interaction of the population causes an expansion in the scope of illegal behavior. In this context, the study of modern mechanisms for combating administrative offenses committed using information technologies is of particular importance. The purpose of the presented study is to analyze the state of modern mechanisms for combating administrative offenses committed using information technologies, identifying existing problems and determining ways to solve them. The author comes to the conclusion that modern mechanisms for countering these acts are characterized by the presence of a number of problems that are objectively determined by the dynamics of information and digital progress, which are ahead of the legal regulation of the stated area, and therefore difficulties arise in identifying, qualifying offenses and imposing fair and proportionate punishment. The fundamental importance of preventive and preventive activities is noted in terms of increasing the level of information and digital literacy to ensure the safe use of modern technologies, which will significantly reduce the vulnerability of the Russian population to offenses of this nature.

When distance enhances closeness

Exploring international students’ long-distance relationships with their back-home families is important for understanding how to support their stability and growth. Using qualitative interviews and surveys, this research explored perspectives from both international students and their parents about their remote interactions while oceans apart. Findings indicate three transformative shifts that enhanced the quality of student-parent relationships through their distance: a) incidental to intentionally motivated interactions, b) task-oriented to person-centered attention, and c) authoritarian to communally-oriented dispositions. These shifts fostered a greater sense of trust, support, and intimacy between international students and their back-home parents. Interweaving Construal Level Theory with the findings, this study offers implications for informing international students and their parents on developing effective, long-distance relationships.

CHARACTERISTICS OF MUTUAL ACTIVATION OF AN INTERGEL SYSTEM BASED ON HYDROGEL POLYMETHACRYL ACID AND POLY-4-VINYL PYRIDINE

The electrochemical properties of mutual activation of polymer networks as a result of remote interaction in an intergel system have been studied. An intergel system consisting of hydrogels of rare crosslinked polymethacrylic acid (hPMAA) and poly-4-vinylpyridine (hP4VP) was chosen as the object of study [1,2]. The purpose of the work is to study the mutual activation features of the intergel system of rare crosslinked hPMAA: hP4VP. The obtained results as the contact time of hydrogels with water increased, zones of maximum and minimum conductivity were observed at the highest points of initial conductivity for different ratios of hPMAA:hP4VP hydrogel systems. In the 6:0 ratio of hPMAA hydrogel, the specific conductivity of the aqueous medium reached its maximum value after one day, and the pH value of the medium decreased relatively to about 4.95. The swelling degree of hPMAA hydrogel was constant at 6:0 different time intervals. In this system, only one polymer, namely hPMAA showed that the hydrogel's water absorption capacity was limited. In the 5:1 ratio of the intergel system, the specific conductivity of the medium reached a high value, and the pH value decreased in the 5:1 ratio. After 2.5 hours of study, a decrease in the conductivity of the aqueous medium was observed at 4:2 hydrogel ratio. After 6 hours, the highest degree of swelling was maintained at 1:5 ratio. In the presence of hP4VP hydrogel at a ratio of 0:6, the pH of the medium increased from 5 to a maximum value of 6.6 within 24 hours. Conclusion. The electrochemical properties of hPMAA:hP4VP hydrogel system were studied by remote interaction. Based on the systematic work, we synthesized the required acidic hydrogel hPMAA:hP4VP and carried out various studies on their properties. To create an intergel system, the obtained hydrogels in seven different proportions were made into an intergel system and their interactions were studied using various physicochemical methods. As a result of the study, the remote interaction of hydrogels in the intergel system leads to conformational changes in their intercellular bonds which undergo additional swelling. As a result of mutual activation, the hydrogels move to a highly ionized state.

Single‐Atom Long‐Range Interaction: Basic Principles and Applications

AbstractSingle‐atom catalysis involves loading the active metal onto the carrier's surface as a single‐atom. This atom is primarily bonded to the carrier surface through hetero‐atom bonding. It is important to note that the coordination environment of the metal atoms may not be the same when each dispersed active metal atom has an identical coordination environment on the carrier's surface. The utilization of single‐atom catalysts (SACs) doesn't strictly imply that a solitary metal atom with zero valency functions as the active core. Singular atoms can also engage in distant interactions with other atoms or clusters of atoms on the substrate, like electron transfer, and frequently demonstrate specific charges. The main reason for the high activity of the catalyst is the remote (i.e., long‐range) interaction of the active atom with the surrounding coordination atoms. For this reason, the study of the mechanism of long‐range interactions between multiple single‐atom sites and between single‐atom sites and atomic cluster sites has become an important and urgent task in the design and regulation of single‐atom catalyst performance.

The clash between physical and digital realm: hybrid movement training during the pandemic

This article is based on ethnographic research conducted in one of the physical training institutions that offer the Laban/Bartenieff Movement Studies (LBMS) certification program in 2021. Because of the COVID-19 pandemic crisis, the training was held in a hybrid format in which some participants were in the studio while others were attending remotely via Zoom. Zoom-mediated movement training for long hours revealed how the intervention of telematic technologies challenged practitioners’ sensorial experience and sense-making process. Moreover, bringing co-located and remote participants’ experiences together in the hybrid setting disclosed different modes of interaction dynamics in the studio and online. Overall, participants described their hybrid experience as a clash. In the article, starting from unfolding those clashes from the enactive perspective, I discuss how remote intercorporeality through an audio–video streaming system, Zoom, challenges participants’ sensorial experience and how remote interaction affects the shared sense-making process in the hybrid format setting.

Efficient thermophilic polyethylene terephthalate hydrolase enhanced by cross correlation-based accumulated mutagenesis strategy

Polyethylene terephthalate (PET) has caused significant pollution issues. Compared to chemical degradation with high energy consumption and cost, enzymatic degradation offers a sustainable solution for PET waste recycling. However, the hydrolytic activity of current PET hydrolases still requires improvement. In this study, a cross-correlation-based accumulated mutagenesis (CAM) strategy was developed to enhance the hydrolysis activity. By mitigating epistatic effect and combinational mutations, we achieved a highly active variant LCC-YGA (H183Y/L124G/S29A) with 2.1-fold hydrolytic activity on amorphous PET films of LCC-ICCG. Conformational analysis elucidated how the introduction of distal mutations enhanced activity. The dynamic correlation among different regions facilitated a synergistic effect, enhancing binding pocket flexibility through remote interactions. Totally, this work offers novel insights and methods for PET hydrolases engineering and provides an efficient enzyme for PET degradation and recycling.

Dynamic evolution and trend prediction in coupling coordination between urban and rural space utilization efficiency based local and tele-coupling model

Optimizing the pattern of territorial space utilization is one of the key tasks to achieve the sustainable development goals. With the accelerating rate of global urbanization, the understanding of territorial space utilization efficiency, role and potential is a prerequisite for alleviating contradictions in urban and rural space distribution. The city cluster is the main form of organization for urban development in future, so the study attempted to explore the urban and rural space utilization efficiency (URSUE) in Chengdu-Chongqing urban agglomeration (CCEC) from coupling coordination degree (CCD) perspective. Considering the gradual increase in the trend of remote interactions between URSUE, we further introduced the Local and Tele-coupling coordination (LTCCD) model that takes into account interactive development relationship between different systems. The results of the study show that: In CCEC, the more economically developed cities indicated that urban spatial utilization efficiency lags behind rural spatial utilization efficiency; The LTCCD in the geographic center region will indicate a higher level but the LTCCD in the economic core cities is higher compared with their CCD level, especially in Chengdu City. This suggests that the LTCCD model is better able to take into account regional development correlations and spatial spillovers effect. This study attempts to explore several key issues of urban-rural spatial allocation in the process of urbanization development and to provide guidance for the territorial space utilization planning in urban agglomerations.

TA-YOLO: a lightweight small object detection model based on multi-dimensional trans-attention module for remote sensing images

Object detection plays a vital role in remote sensing applications. Although object detection has achieved proud results in natural images, these methods are difficult to be directly applied to remote sensing images. Remote sensing images often have complex backgrounds and small objects, which results in a highly unbalanced distribution of foreground and complex background information. In order to solve the above problems, this paper proposes a multi-head channel and spatial trans-attention (MCSTA) module, which performs remote pixel interaction from the channel and spatial dimensions respectively to complete the attention feature capture function. It is a plug-and-play module that can be easily embedded in any other natural image object detection convolutional neural network, making it quickly applicable to remote sensing images. First, in order to reduce computational complexity and improve feature richness, we use a special linear convolution to obtain three projection features instead of the simple matrix multiplication transformation in Transformer. Second, we obtain trans-attention maps in different dimensions in a manner similar to the self-attention mechanism to capture the interrelationships of features in channels and spaces. In this process, we use a multi-head mechanism to perform parallel operations to improve speed. Furthermore, in order to avoid large-scale matrix operations, we specially designed an attention blocking mode to reduce computer memory usage and increase operation speed. Finally, we embedded the trans-attention module into YOLOv8, added a new detection head and optimized the feature fusion method, thus designing a lightweight small object detection model named TA-YOLO for remote sensing images. It has fewer parameters than the benchmark model YOLOv8, and its mAP on the PASCAL VOC and VisDrone data sets increased by 1.3% and 6.2% respectively. The experimental results prove the powerful function of the trans-attention module and the excellent performance of TA-YOLO.

Seneca: Taint-Based Call Graph Construction for Java Object Deserialization

Object serialization and deserialization are widely used for storing and preserving objects in files, memory, or database as well as for transporting them across machines, enabling remote interaction among processes and many more. This mechanism relies on reflection, a dynamic language that introduces serious challenges for static analyses. Current state-of-the-art call graph construction algorithms do not fully support object serialization/deserialization, i.e., they are unable to uncover the callback methods that are invoked when objects are serialized and deserialized. Since call graphs are a core data structure for multiple types of analysis (e.g., vulnerability detection), an appropriate analysis cannot be performed since the call graph does not capture hidden (vulnerable) paths that occur via callback methods. In this paper, we present Seneca, an approach for handling serialization with improved soundness in the context of call graph construction. Our approach relies on taint analysis and API modeling to construct sound call graphs. We evaluated our approach with respect to soundness, precision, performance, and usefulness in detecting untrusted object deserialization vulnerabilities. Our results show that Seneca can create sound call graphs with respect to serialization features. The resulting call graphs do not incur significant runtime overhead and were shown to be useful for performing identification of vulnerable paths caused by untrusted object deserialization.

Unpaid carers of people with dementia and information communication technology: Use, impact and ideas for the future.

Several 100,000s of people living with dementia in the UK are cared for at home by a spouse or relative. Few studies have considered the ICT needs and experiences of unpaid carers. This study explores the types of ICT unpaid carers use, the ways they use ICT, the impact of ICT-use, and their ideas for how ICT could be more supportive of their role as a carer. Six focus groups with 32 unpaid carers of people living with dementia discussed their experiences of - and barriers to - using ICT. Transcripts were analysed thematically according to three types of ICT (mainstream, accessible and formal) and five functions (supporting domestic tasks, care management, monitoring, communication and information and education). Participants predominantly used mainstream ICT devices such as laptops and smartphones and internet-enabled applications including videoconferencing and social media platforms to support their daily activities and assist them in their caring role. A few participants discussed using accessible devices such as memory clocks and formal telecare and care-phone services for care management and monitoring functions. Participants' ideas for improvements centred on personalised communication applications that facilitate remote interactions and promote persons living with dementia's independence. Others expressed concerns about the growing need to use ICT to access formal care services and the inadequacy of the ICT infrastructure in some care homes. Unpaid carers mostly turn to readily available mainstream ICT to support their personal and care activities. Further research is required to understand the social impact of the increasing reliance of ICT across health, social and residential care service sectors. Improved cooperation between unpaid carers, technology developers and care services providers could align ICT development to the needs and experiences of families living with dementia and assist unpaid carers with identifying ICTs that optimally support their personal circumstances.

Revolutionizing Higher Education Teaching Evaluation with Interactive Mobile and Mixed Reality: A Methodological and Applied Analysis

In higher education, it is imperative to maintain educational quality, which requires necessitates a thorough evaluation of teaching methods. The advent of mixed reality (MR) technology, combined with interactive mobile capabilities, introduces innovative possibilities for traditional educational assessment frameworks. This study is dedicated to investigating the application of MR and interactive mobile technologies in higher education teaching evaluations, with a focus on assessing their effectiveness and implementation outcomes. Research to date has explored MR’s educational applications. However, the integration of interactive mobile technologies alongside MR in developing specific methodologies and evaluative tools for teaching evaluations has not been fully realized. This underutilizes the combined potential of these technologies. This paper is anchored in two principal research endeavors. Initially, it delves into the construction of a meta-model facilitated by MR-aided and interactive mobile-enhanced teacher-student interactions, utilizing a hierarchical remote interaction pyramid model. This process involves developing extensible associative functions, determining index weights, and establishing evaluation levels, which collectively enhance the evaluation’s multidimensionality, interactivity, and scientific precision. Subsequently, the analytic hierarchy process (AHP) is employed to quantitatively assess the educational impact of MR and interactive mobile experiences on students. This approach provides support for customized and precise teaching evaluations. The findings reveal that integrating MR technology with interactive mobile capabilities significantly enhances the interactivity and systematic scientific approach of teaching evaluations. This fosters a more multidimensional and interactive framework for educational evaluation.

Microstrain-Stimulated Elastico-Mechanoluminescence with Dual-Mode Stress Sensing.

Elastico-mechanoluminescence technology has shown significant application prospects in stress sensing, artificial skin, remote interaction, and other research areas. Its progress mainly lies in realizing stress visualization and 2D or even 3D stress-sensing effects using a passive sensing mode. However, the widespread promotion of mechanoluminescence (ML) technology is hindered by issues such as high stress or strain thresholds and a single sensing mode based on luminous intensity. In this study, a highly efficient green-emitting ML with dual-mode stress-sensing characteristics driven by microscale strain is developed using LiTaO3:Tb3+. In addition to single-mode sensing based on the luminous intensity, the self-defined parameter (Q) is also introduced as a dual-mode factor for sensing the stress velocity. Impressively, the fabricated LiTaO3:Tb3+ film is capable of generating discernible ML signals even when supplied with strains as low as 500 µst. This is the current minimum strain value that can drive green-emitting ML. This study offers an ideal photonic platform for exploring the potential applications of rare-earth-doped elastico-ML materials in remote interaction devices, high-precision stress sensors, and single-molecule biological imaging.

Online therapy with families - what can families tell us about how to do this well? A qualitative study assessing families' experience of remote Dyadic Developmental Psychotherapy compared to face-to-face therapy.

Dyadic Developmental Psychotherapy (DDP) is a family-based therapy for adopted children aiming to achieve secure attachment between the child and parent. Due to restrictions under the COVID-19 pandemic, delivery of DDP transitioned from face-to-face to online methods. This study aimed to explore families experience of online DDP compared to face-to-face DDP, looking at the advantages and disadvantages of remote delivery methods and the implications this has on future service delivery for clinicians. Semi-structured interviews with 6 families were conducted online. Analysis of transcripts using Interpretative Phenomenological Analysis (IPA) revealed four superordinate themes: environment and child engagement, non-verbal communication, travel and familiarity with remote interactions. Parents recognised the influence the physical and online environment had on their child's engagement levels, however, varied in their experience and hence preference of delivery method. All families emphasised the importance of non-verbal communication within DDP sessions and majority highlighted this may be lost online. For families who travelled to face-to-face DDP, car journeys provided a unique opportunity to decompress and reflect after sessions. For families where travel is unfeasible, online DDP was a lifeline, demonstrating the ability of remote therapy to widen access to specialist healthcare. Familiarity with online work emerged as a strong indicator of positive attitudes towards remote DDP, especially if the previous experience is positive and the child is confident using technology. Overall, families differed greatly in their experience of remote and face-to-face DDP indicating a new approach must be undertaken with each family beginning therapy, ensuring it is unique and individual to their needs.

Machine Learning-Assisted Wearable Thermo-Haptic Device for Creating Tactile Sensation

The tactile modality is an important source of human experience and emotional expression, either on its own or by intensifying and complementing other senses, influencing our interactions with objects, people, animals and other beings. Following this, developed haptic devices transmit information to the user using tactile stimuli to increase or change sensory input. Haptics are an important factor that makes virtual worlds and remote interpersonal interaction tangible. Haptic feedback consists of more components that make an experience physically perceptible and realistic. Haptic feedbacks are widely used in mobile and wearable devices to convey various types of notifications to users. In this study, it was aimed to develop a new generation of wearable gloves against the hypoesthesia problem by combining artificial intelligence and thermohaptic, which are popular in many fields.

Live vs video interaction: sensorimotor and visual cortical oscillations during action observation.

Increasingly, in the field of communication, education, and business, people are switching to video interaction, and interlocutors frequently complain that the perception of nonverbal information and concentration suffer. We investigated this issue by analyzing electroencephalogram (EEG) oscillations of the sensorimotor (mu rhythm) and visual (alpha rhythm) cortex of the brain in an experiment with action observation live and on video. The mu rhythm reflects the activity of the mirror neuron system, and the occipital alpha rhythm shows the level of visual attention. We used 32-channel EEG recorded during live and video action observation in 83 healthy volunteers. The ICA method was used for selecting the mu- and alpha-components; the Fourier Transform was used to calculate the suppression index relative to the baseline (stationary demonstrator) of the rhythms. The main range of the mu rhythm was indeed sensitive to social movement and was highly dependent on the conditions of interaction-live or video. The upper mu-range appeared to be less sensitive to the conditions, but more sensitive to different movements. The alpha rhythm did not depend on the type of movement; however, a live performance initially caused a stronger concentration of visual attention. Thus, subtle social and nonverbal perceptions may suffer in remote video interactions.

Социокультурная регуляция гражданской позиции молодежи в цифровой среде

The article is devoted to issues related to the problem of the formation and evolution of the civic position of youth in the digital environment. The authors consider traditional and digital mechanisms of sociocultural regulation of youth civic positioning. The article substantiates the need to search for methods of sociopsychological reinforcement in the process of forming a constructive civic position of young people. The authors point out that digital technologies create intermediary channels that, on the one hand, allow you to include in communication those participants who would not be able to interact without a digital environment, but on the other hand, reduce quality and weaken such effects as direct infection and copying. In this regard, an important issue for the modern digital society is the task of ensuring the transfer of knowledge and skills, the transfer of skills through the mediation of digital telecommunications technologies in remote work, study and online interaction.
