Analysis of 5G technology for games and communication

Thanks to the joint work of industry companies, new devices are already entering the market and 5G networks and infrastructure are being actively deployed. And very soon real 5G gadgets will go on sale! In this article I want to talk about the new opportunities that the 5G era can give people. And these features, including those we have already talked about, are getting closer to users. Let’s talk today about what the advent of the 5G era means for games and communications. The key to the success of 5G cloud gaming is a good strategy that brings the right gaming games to an affordable market with the right infrastructure and coverage and provides a business case that delivers growth and expected ROI. 5G allows developers to deal with the problem of delays and gives them and users completely new features. We believe that with fifth-generation network technology, the very concept of "lag" in games will soon be forgotten, and the combination of 5G and augmented reality in multiplayer mobile AR-games will help bring mobile gaming to a whole new level. Using only smartphones, you and your friends will be able to play augmented reality paintball to combine the real world with the elements of the virtual. As in today’s paintball battle, when you need to run around the field and shoot balls of paint at your friends, you will catch them in the "sight" of your smartphone and tap the screen to fire digital paintball shells. In addition to reducing latency, 5G technology and artificial intelligence will help to ensure complete immersion in the game with quality graphics and new effects. For example, when one such virtual projectile hits the clothes, the ball will not just bounce off it, as in 4G games, it will make the fabric bend at the point of impact, and then in real time it will fill it with a bright.

Indigenous knowledge and Language Revival in Post-colonial Education in Papua New Guinea

Although Papua New Guinea (PNG) has more languages than any other country in the world, the education system in PNG inherited at Independence from Australia in 1975 is modelled on the Australian system and is therefore monolingual and centralised. Children in PNG are currently educated in English, a language they rarely encounter outside of school, with curriculum and textbooks produced by persons not from the students’ own cultural background, often overseas or by resident foreigners. An ineffectively organised attempt by the national government to introduce limited early education in local languages and the perception that educational standards have dropped since Independence in 1975 limit public support for education in Papua New Guinean languages (Volker 2015a). This paper describes a two-month inter-disciplinary workshop in the Nalik-speaking community in the New Ireland Province (NIP) of PNG. Nalik, one of 23 languages in New Ireland Province, is spoken by approximately 4000 people in 15 villages on the east and west coasts of the northern part of New Ireland, 70-90 kilometres from the provincial capital, Kavieng (Volker 2015b, 210). The purpose of the project was to test ways of introducing customary knowledge and language into grade six and seven classwork (Silva 2017). The workshop focused on the representations that birds have in Nalik culture, as birds are present in many stories and represent clan totems in Nalik culture. Thus, they play a central role in Nalik culture, helping people to understand philosophical principles at the core of Nalik society and to identify particularly significant words and expressions in the Nalik culture. The children in the workshop were given the research task of interviewing elders about local bird names, traditional laws about birds, and stories or narratives related to birds. The students researched significant Nalik biological or philosophical terms, described these in English, and linked these to their knowledge in the social and natural sciences. Because they were aware that their findings would be collectively published as a book, students exercised caution and precision in their use of both Nalik and English terminology. Following the production of the book, and by using an action-research method, Nalik community members assisted in the content of the book, and in this way limited errors outside researchers might have introduced when writing about their culture. The project received strong support from parents and community leaders, with one chief attending almost all sessions in order to eventually lead similar workshops. Rather than as an attempt at a complete language revival (e.g., as in much more comprehensive projects set out by Fishman 2001), this project must be seen as a first, but important, attempt to assist students to increase their awareness of Nalik language, and to improve their desire to be competent in both the language of education (English) and their ancestral language (Nalik). The classes with the students therefore go beyond formulaic language learning, but do not comprise a complete immersion or neighbourhood language program. Parents reported an increase in students’ care in writing in English (as seen in the high number of students doing well in the competitive high school entrance examinations), and clan elders reported a greater understanding of the “classical” Nalik terminology used in traditional contexts. In this way children can be better educated for participation in their own society. This project has shown that traditional knowledge can be introduced into schools, and in English, without disrupting the use of a national curriculum, and therefore has significant ramifications in methods of revitalising a language through redesigned pedagogies, which we believe can be extended to other cultural and linguistic contexts.

Metaverse – how is it in Russian? About the Construction of the Russian sector of the Metaverse

The article from various angles examines the topic of the so-called "metaverse" that has suddenly become "fashionable". The authors raise the question of the origins, history, and the real degree of novelty of the term and the real objects and processes designated by it. They concluded that the qualitative novelty of the metaverse concept is somewhat exaggerated: it describes (reflects) only the next stage in the development of virtual simulations, or, in other words, web 3.0. At this level, complex spatial configurations of sensory interfaces become possible, but there is no complete immersion of a person into an imaginary (programmed) world: a person is aware of the virtual nature of the sensations offered to him. However, according to the authors, not such amusements, but opportunities, and prospects for the use of complex digital models in new economic and social processes are interesting. The authors raise the question of the possibility and necessity of developing the "Russian sector of the metaverse" and state their views on the ways of such development.

Optimizing the pontoon of a composite dock when changing a ratio of the sides’ length in a reinforced-concrete slab

This paper investigates the local strength of reinforced-concrete slabs in a pontoon of the composite floating dock under uniform hydrostatic load. A refined approach was applied to calculate the reinforced-concrete slabs considering the difference in the mechanical characteristics of concrete exposed to stretching and compression. The length of the zone of fixation that impacts concrete compression and stretching has been determined, which is 0.22 lengths of the short side of the rectangular slab. To this end, preliminary calculations of stresses in slabs made from a non-composite homogeneous material were performed, at different sizes of thickness and ratios of the slabs’ side lengths. A finite-element model of the reinforced concrete slab was built, with its reinforcing elements in the longitudinal and transverse directions. The model accounts for differences in the mechanical characteristics, which are set separately for the compressed and stretched regions of concrete. The stressed-strained state of rectangular reinforced concrete slabs has been estimated for the case of complete immersion of the pontoon in quiet water under the influence of uniform hydrostatic pressure, without taking into consideration possible dynamic loads. When simulating the bottom slabs, the length of the larger side of the supporting contour was taken equal to the distance between the longitudinal walls, based on the structural size of the dock. The length of the short side varied multiple to the longitudinal quad, making it possible to acquire data for a wide range of side length ratios, from 3.3 to 1, most characteristic of ship structures. The compressed and stretched areas of concrete were simulated separately, with the mechanical characteristics of strength and rigidity corresponding to the materials used in the construction of floating docks. The charts of maximum stresses in concrete and slab reinforcement depending on the length of the short side of the supporting contour have been built. This has made it possible to determine the optimum width of the slab, which is equal to 3 m for the considered structure under predefined loading. The applied approach makes it possible to optimize the size of such structures in terms of weight and material consumption

CONCEPTUALIZATION OF CULTURAL INTELLIGENCE, INTERCULTURAL SENSITIVITY, INTERCULTURAL COMPETENCE, AND NOMOLOGICAL NETWORK: a contact hypothesis study of sociology of education

This paper presents a qualitative research examining the extent to which sojourns abroad engage their partakers in intercultural interactions and explores whether experiences like this translates into intercultural growth in students. The results of this study demonstrated that studying abroad would not suffice for complete immersion into the local community or allow one to discover the nuances of another culture in their entirety. Nonetheless, students who were surrounded by their local and international counterparts were exposed to foreign cultures, and were motivated to explore and interpret the diversity they encountered. They were thus equipped with knowledge of unfamiliar cultures and were sensitised to cultural diversity. Such contact often challenged the students’ established opinions and ideas, which largely stemmed from stereotypes about specific cultures. Rethinking this, to varied extents, resulted in evolved attitudes and values. International engagement also stimulated introspection and a deepened understanding of identity among the students, thereby contributing to their self-awareness. By offering opportunities to experience cultural diversity, the sojourn prompts students to develop coping strategies and draw parallels with their own culture, along with fostering intercultural development to a certain degree, and is therefore of great significance for policy makers, curriculum developers, teachers and tertiary students.

Robert Koch’s Professional and Personal Life

All creative people, whose names we remember, are united by such a character trait as passion. And the field of creativity is not so important here — both in art, and in technical sciences, and in medicine, to achieve a result, complete immersion in research, some kind of obsession is necessary. Robert Koch (1843-1910) — a great researcher, a German physician, microbiologist and hygienist, proved by his own example that a clear goal, fortitude and efficiency overcome all unfavorable circumstances. This work examined the life and work of Robert Koch over a significant period of time — from graduation to the discovery of tuberculin, its announcement as a treatment for tuberculosis and the recognition of the fallacy of this statement. From the point of view of the authors of the work, this period of time is of great interest. We see Robert Koch — a scientist with extraordinary abilities and a unique combination of character traits. Diligence and the highest ability to work, exactingness towards himself, a clear organization of work, the ability not to stop in the face of difficulties — predetermined the success of his research.

Medical Pedagogy in the Time of COVID-19

Medical teaching is about giving a student a collaborative experience of the art and skill of the practice of medicine. This is acquired through authentic patient experiences. A clinical teacher uses clinical lectures, simulations, lab sessions, small group interactions, cadaver dissection and technical classes (eg: ultrasound) to create a complete clinical immersion experience. For this we use both the in-patient and out-patient facilities.

Aging mechanism and surface properties of Silica fluoropolymer coating and its application

The hydrothermal aging cycles experiment was carried out on synthetic Silica fluoropolymer coating (SiO2-FP). The hydrothermal aging mechanism, surface properties and protective efficacy on sandstones was studied. For comparison, the same study was conducted for commercial protective material acrylic resin Paraloid B72 (PB72). The hydrothermal aging mechanism was studied by Fourier infrared spectroscopy attenuated total reflection technique (ATR-FTIR) and x-ray photoelectron spectroscopy (XPS) technology. The surface properties were characterized by field emission scanning electron microscope (SEM), the CR-400 color difference meter, static contact angle and GMT6503 Electronic universal Tensile machine. The capillary water absorption, water absorption by complete immersion (CI) and water vapor permeability were measured to evaluate the protective efficacy on sandstones after treatment. The results of ATR-FTIR and XPS indicated that part of the ester groups in PB72 was hydrolysed and the chemical structure of SiO2-FP was not changed but only microphase separation occurred after 360 h of aging. After 360 h of aging, the PB72 film had obvious change and the SiO2-FP film only shown a minor change; the color change of PB72 film was very obvious and the color change of SiO2-FP film was within the acceptable range; the PB72 film changed from hydrophobic to hydrophilic and the SiO2-FP film still retained high hydrophobicity (119.3°); the SiO2-FP had a higher adhesive strength than PB72 at the end of aging. Compared with PB72, the SiO2-FP can obviously reduce the capillary water absorption and had a higher protective efficiency (97.25%), much lower soakage capacity (0.60%), higher water vapor permeability (267.0 ± 2) and less influence on the water vapor permeability. All the results demonstrated that the SiO2-FP has much better anti-aging ability and longer durability under hydrothermal condition. The SiO2-FP can provide adequate protection for sandstones. The SiO2-FP can be used as a suitable protective coating on sandstones.

Graph immersions with parallel cubic form

We consider non-degenerate graph immersions into affine space An+1 whose cubic form is parallel with respect to the Levi-Civita connection of the affine metric. There exists a correspondence between such graph immersions and pairs (J,γ), where J is an n-dimensional real Jordan algebra and γ is a non-degenerate trace form on J. Every graph immersion with parallel cubic form can be extended to an affine complete symmetric space covering the maximal connected component of zero in the set of quasi-regular elements in the algebra J. It is an improper affine hypersphere if and only if the corresponding Jordan algebra is nilpotent. In this case it is an affine complete, Euclidean complete graph immersion, with a polynomial as globally defining function. We classify all such hyperspheres up to dimension 5. As a special case we describe a connection between Cayley hypersurfaces and polynomial quotient algebras. Our algebraic approach can be used to study also other classes of hypersurfaces with parallel cubic form.

The Calabi–Yau problem for Riemann surfaces with finite genus and countably many ends

In this paper, we show that if R is a compact Riemann surface and M=R\setminus\bigcup_i D_i is a domain in R whose complement is a union of countably many pairwise disjoint smoothly bounded closed discs, D_i , then there is a complete conformal minimal immersion X\colon M\to\mathbb{R}^3 , extending to a continuous map X\colon \overline M\to\mathbb{R}^3 , such that X(bM)=\bigcup_i X(bD_i) is a union of pairwise disjoint Jordan curves. In particular, M is the complex structure of a complete bounded minimal surface in \mathbb{R}^3 . This extends a recent result for finite bordered Riemann surfaces.

Using deliberate mind-wandering to escape negative mood states: Implications for gambling to escape

Background and aims: Slot machines are a pervasive form of gambling in North America. Some gamblers describe entering “the slot machine zone”—a complete immersion into slots play to the exclusion of all else. Methods: We assessed 111 gamblers for mindfulness (using the Mindful Attention Awareness Scale (MAAS)), gambling problems (using the Problem Gambling Severity Index (PGSI)), depressive symptoms (using the Depression, Anxiety, and Stress Scale), and boredom proneness (using the Boredom Proneness Scale). In a counterbalanced order, participants played a slot machine simulator and completed an auditory vigilance task. During each task, participants were interrupted with thought probes to assess whether they were: on-task, spontaneously mind-wandering, or deliberately mind-wandering. After completing each task, we retrospectively assessed flow and affect. Compared to the more exciting slots play, we propose that gamblers may use deliberate mind-wandering as a maladaptive means to regulate affect during a repetitive vigilance task. Results: Our key results were that gamblers reported greater negative affect following the vigilance task (when compared to slots) and greater positive affect following slots play (when compared to the vigilance task). We also found that those who scored higher in problem gambling were more likely to use deliberate mind-wandering as a means to cope with negative affect during the vigilance task. Using hierarchical multiple regression, we found that the number of “deliberately mind-wandering” responses accounted for unique variance when predicting problem gambling severity (over and above depression, mindfulness, and boredom proneness). Conclusions: These assessments highlight a potential coping mechanism used by problem gamblers in order to deal with negative affect.

Improving carbonate rock hardness by consolidating additives to sustain long term fracture conductivity

Fracture conductivity is a fracture's capacity to deliver fluids from the hydrocarbon reservoir to the wellbore. Sustaining long-term fracture conductivity results in better well productivity and reserve recovery. Harder rocks tend to sustain conductivity better than do weak and ductile rocks because they are less likely to suffer from proppant embedment and the crushing and creeping of asperities. This study shows that the hardness of carbonate rocks can be improved significantly when they are treated with carbonate-consolidating chemicals. Ideally, this should be done without damaging the matrix permeability. This research tested the capacity of microemulsion, calcium hydroxide (Ca(OH)2) nanoparticles, and tetraethyl orthosilicate (TEOS) to consolidate carbonate rocks. These are all believed to improve rock hardness by enhancing carbonate grain attachment. The treatments were applied to cores and slabs of Mississippian Indiana limestone and permo-carboniferous Khuff carbonate rocks. These chemicals were tested by either impregnation or complete immersion of the rock sample in a solution. SEM, X-ray fluorescence, porosity, permeability, and rock hardness were all measured before after the treatment. It was observed that the rock surface Young's modulus could be improved by 10%–38%. Matrix permeability was reduced by 50% when Ca(OH)2 nanoparticles were tested. Nevertheless, the TEOS improved the carbonate rock's hardness and permeability 18% and 44%, respectively. A modeling study has also been provided to explain the impact of fractured rock strengthening on productivity improvement.

Stimulation of the Visual System Using a Cognitive Task in a Virtual Environment in Patients with Schizophrenia and Depression

This paper describes research data that evaluated the effect of a course of visual stimulation with a cognitive task in an interactive virtual environment on the functioning of the magno- and parvo-systems in patients with schizophrenia and depression. To demonstrate the images, a large-angular-size monitor was used, which provided a more complete immersion of the subjects into a virtual environment. To assess the effectiveness of the technique, we used the analysis of the amplitude of the components of cognitive visual evoked potentials in the demonstration of images that differ in physical features (spatial-frequency spectrum) for selective activation of low-frequency (magno) and high-frequency (parvo) channels and semantic features (objects of living and inanimate nature). It was shown that in patients of both groups a decrease in the amplitude of the components of evoked potentials to stimuli, filtered mainly by high spatial frequencies (parvo-system), is observed. There was evidence that patients with schizophrenia experienced disturbances of the processing of visual information, both in the early and late stages. In depressed patients, only the early stages of processing are affected. After a course of exposure to interactive virtual environments with a cognitive task, patients with schizophrenia experience improvement in the processing of visual information, both at the early and late stages. In depressed patients, improvement occurred at the early stages of treatment. In patients of both groups, a significant increase in the amplitude of the components of cognitive visual potentials at high spatial frequencies (parvo-system) is observed. Thus, the result of the course of exposure is a pronounced activation of the parvo-system, namely, the system that is more affected in these patients.

Effects of Erosion Form and Admixture on Cement Mortar Performances Exposed to Sulfate Environment

The effects of the admixtures, erosion age, concentration of sulfate solution, and erosion form of sulfate attack on the mechanical properties of mortar were investigated. Simultaneously, the microstructure, pore characteristics, kinds and morphologies of erosion products of mortar before and after sulfate attacks were performed by Mercury Intrusion Porosimetry (MIP), Environment Scanning Electronic Microscope and Energy Dispersive Spectrometer (ESEM-EDS). In addition, the crystal form and morphology characteristics of crystallization on mortar surfaces attacked by partial immersion form were studied. The results showed that the compressive and flexural strengths of mortar attacked by sulfate for four months decreased with the increase of the replacement of cement with fly ash, and the corresponding strength of mortar containing slag first increased and then decreased. The admixtures can improve the microstructure and mechanical properties of mortar within the replacement ratio of 10%. Although the change laws of the mortar specimens containing different admixtures were similar, the mortar containing slag had an excellent sulfate resistance under the same condition. Compared with the complete immersion form, the strength variation of the mortar containing fly ash attacked by semi-immersion form was less. The porosity and average pore diameter of mortar attacked by sulfate for four months increased, and the percentage of micropore with the pore diameter less than 200 nm increased. Plenty of rod-like and plate-like erosion products were generated in mortar attacked by a sulfate solution with a high concentration. A larger number of fibrous and flocculent crystallization covered the mortar’s surface containing fly ash, but it was a granular and dense crystallization formed on the mortar’s surface containing slag. Much dendritic erosion product was generated in the mortar attacked by semi-immersion form, and ESEM-EDS analysis revealed that it may be scawtite, spurrite, and residue of the decomposed calcium silicate hydrate (CSH) in the inner mortar; however, the crystallization sodium sulfate was crystallized on mortar surface.

Flow Experience in Blended Learning: Behind the Inconsistent Effects of Flexibility and Interaction

Despite the growing importance of blended learning environments in management education, the extant research provides inconsistent results. While many studies find positive effects of blended environments or their central characteristics (i.e., flexibility and interaction) on learning effectiveness, dropout rates remain high and learners prefer face-to-face encounters over online activities. As the cognitive mechanisms behind learning effectiveness have been neglected thus far, we draw on educational psychology to derive an explanation for these contradictions. We introduce flow theory, which describes a learner’s complete immersion in an activity, and we propose that experiencing flow mediates the positive effects of flexibility and interaction on blended learning effectiveness. The results of an experiment with 115 graduate management students support our hypotheses. We contribute to management education research on blended learning environments by looking beyond the direct effects of format characteristics on learning outcomes. We reveal cognitive characteristics, especially flow experience, as an important mediator. Consequently, management education scholars should consider indirect effects from related disciplines when investigating blended learning environments. Furthermore, instructors should ensure that they integrate flexibility and interaction into blended learning environments, and they should account for cognitive learner characteristics.

Discriminating affective state intensity using physiological responses

In this paper we explore if physiological signals obtained from a person through wearable sensors permit the correct interpretation of human affective states. A crucial aspect within this field of research is the capability of inducing real-life emotions in laboratory environments. To this end we designed a very strict and regulated experimental protocol. We consider two affective states: a relaxation state and a stressful one. To induce these two states we adopt audio tracks of natural or day-life sounds and math calculations. Moreover, to study different intensities of effectively induced relaxation, we consider two different audio players: a traditional pair of headphones and the Spherison Sound6D pillowⒸ, a special device that provides a complete spherical immersion in what users are listening to. We consider as physiological signals the Galvanic Skin Response (GSR) and the Photoplethysmography (PPG), as they are sensitive measures for emotional arousal. After an extensive analysis on our experimental data, we demonstrate that GSR and PPG signals can successfully distinguish relaxation and stressful states. Moreover, the same physiological signals can discriminate affective state intensity, especially when relaxation is induced adopting the Sound6D technology.

Biodegradable Polyanhydrides as Encapsulation Layers for Transient Electronics

AbstractBioresorbable electronic systems represent an emerging class of technology of interest due to their ability to dissolve, chemically degrade, disintegrate, and/or otherwise physically disappear harmlessly in biological environments, as the basis for temporary implants that avoid the need for secondary surgical extraction procedures. Polyanhydride‐based polymers can serve as hydrophobic encapsulation layers for such systems, as a subset of the broader field of transient electronics, where biodegradation eventually occurs by chain scission. Systematic experimental studies that involve immersion in phosphate‐buffered saline solution at various pH values and/or temperatures demonstrate that dissolution occurs through a surface erosion mechanism, with little swelling. The mechanical properties of this polymer are well suited for use in soft, flexible devices, where integration can occur through a mold‐based photopolymerization technique. Studies of the dependence of the polymer properties on monomer compositions and the rates of permeation on coating thicknesses reveal some of the underlying effects. Simple demonstrations illustrate the ability to sustain operation of underlying biodegradable electronic systems for durations between a few hours to a week during complete immersion in aqueous solutions that approximate physiological conditions. Systematic chemical, physical, and in vivo biological studies in animal models reveal no signs of toxicity or other adverse biological responses.

A Study of the Durability of Concrete Reinforced with Hemp Fibers Exposed to External Sulfatic Attack

Abstract The purpose of this paper is to study the durability of concrete reinforced with hemp fibers in the face of external Sulfatic attack. For this purpose, five types of concrete were formulated; three types of concrete reinforced with hemp fibers (HC-0.25, HC-0.5, and HC-1) at 0.25%, 0.5%, and 1 % of hemp fibers in volume, respectively. And two control concretes, being ordinary concrete (OC) and polypropylene fiber reinforced concrete (PC). To assess the sulfatic attacks, the described concrete types underwent two aging protocols: 1) a complete immersion in 12.5 % Sodium Sulfate (Na2SO4) solution, and 2) an accelerated aging protocol consisting of immersion/drying in the same sulfate solution at a temperature of 60°C. The results show that concrete reinforced with 0.25 % of hemp fibers is the optimal amount compared to control concretes in terms of physico-mechanical performance and durability under sulfate attack. This number of fibers could enable the production of green and durable structural concretes based on untreated hemp fibers.

Pathogenicity of commercial entomopathogenic fungal strains on the avocado seed borer (ASB), Heilipus lauri (Coleoptera: Curculionidae) under laboratory conditions

The avocado seed borer, (ASB) Heilipus lauri Boheman 1845 (Coleoptera: Curculionidae) is an official quarantine pest limiting avocado production and fruit exports from Colombia to pest-free countries. To provide alternatives to manage ASB, the objective of this study was to determine the potential use of commercial strains of Beauveria bassiana and Metarhizium anisopliae as biological control agents of this pest. Pathogenicity of the strains was evaluated by complete immersion of the insect in a spore solution (direct inoculation) or by insect contact with inoculated fruit (indirect inoculation). The B. bassiana strain caused higher mortality (DF = 3, F = 25.7, P = 0.0002), showing an almost eight-fold increase, 55% and 79% mortality, for both concentrations used, 2.5 × 108 spores/mL or 2.5 × 109 spores/mL, respectively. Additionally, the B. bassiana strain showed shorter median survivorship using direct inoculation (15.8 to 8.7 days), a longer delay in the feeding initiation time (50 h), and a decrease in the fruit intake (Anti-feeding index above 50) after indirect inoculation. To our knowledge, this is the first report about the pathogenicity of a commercial B. bassiana strain against ASB in Colombia.
