description: Elektr energiyasini yuqori kuchlanishli tarmoqlar orqali uzatish jarayonida isroflar ortib bormoqda. Bunda energiyani uzatishda o‘tkazgichlarda, o‘zgartirgich qurilmalarida xam energiya yuqolish jarayoni sodir bo‘ladi. Energiya isroflarini kamaytirish uchun jo‘natiladigan kuchlanish kuch transformatorlari orqali iste'molchilarga yetkaziladi. Nimstansiyalarda o‘rnatiladigan uskunalar esa energiyani nazorat qilish, uning joriy xolatini tekshirish, isroflarni kamaytirish hamda elektr energiyasining sifat ko‘rsatkichlarini nazorat qilishga imkon beradi.
description: Energy losses during transmission through overhead power grids are quite high. Power is lost both in equipment that provides energy conversion and in long wired lines. The losses of electricity in the wires depend on the strength of the current, therefore, when transmitting it over long distances, the voltage is increased using transformers, reducing the strength of the current by the same amount, which, when transmitting the same power, can significantly reduce losses. However, as the voltage increases, various discharge phenomena begin to occur, which also contribute to the losses. The equipment installed at the nodal stations for the redistribution of electricity makes it possible to control energy flows and their parameters, as well as to assess losses and quality of electricity.

description: Solar collectors absorb the energy of solar radiation and convert it into thermal energy of the environment and are used for heating and hot water supply. This is due to the fact that sunlight is unstable during the day, and the need for hot water and heating exists even in the absence of sunlight, so it is extremely important to determine the necessary amount of heat when using solar energy.

Modeling the initiation of the 2006 December 13 coronal mass ejection in AR 10930: the structure and dynamics of the erupting flux rope

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We carry out a three-dimensional magneto-hydrodynamic (MHD) simulation to model the initiation of the coronal mass ejection (CME) on 13 December 2006 in the emerging δ-sunspot active region NOAA 10930. The setup of the simulation is similar to a previous simulation by Fan (2011), but with a significantly widened simulation domain to accommodate the wide CME. The simulation shows that the CME can result from the emergence of a east-west oriented twisted flux rope whose positive, following emerging pole corresponds to the observed positive rotating sunspot emerging against the southern edge of the dominant pre-existing negative sunspot. The erupting flux rope in the simulation accelerates to a terminal speed that exceeds 1500 km/s and undergoes a counter-clockwise rotation of nearly 180 degrees such that its front and flanks all exhibit southward directed magnetic fields, explaining the observed southward magnetic field in the magnetic cloud impacting the Earth. With continued driving of flux emergence, the source region coronal magnetic field also shows the reformation of a coronal flux rope underlying the flare current sheet of the erupting flux rope, ready for a second eruption. This may explain the build up for another X-class eruptive flare that occurred the following day from the same region.

Quasi-static and Impact Behaviour of Innovative Hybrid Corrugated (HC) Members

description: In today’s world, organised research and development have greatly increased the production of new knowledge. Over the past few decades, innovations and the outcome of innovative activities have surrounded us; some affect our life more than others while some are more noticeable than others. Indeed, technology evolution gradually forms our modern life. On this journey, structural engineers are not an exemption though. They have always been trying to find more resilient structural members in order to build high performance infrastructure. As an attempt to achieve this goal, innovative Hybrid Corrugated (HC) sections are introduced and examined in this thesis.
 The HC sections exhibit superior behaviour in comparison to conventional tubular sections, not only on the performance of structures, but also from an aesthetic point of view. The square shape of these hollow sections are comprised of four corrugated plates which may or may not have corner tubes welded to the apexes of the section. The material of plates is from medium strength structural steel whilst it is ultra-high strength steel for the corner tubes.
 The major objective of this research work is to investigate the behaviour of HC members under quasi-static and impact loadings. For the former loading case, the full-scale HC sections are loaded under axial compression and four-point bending. The latter loading case is addressed through a falling mass dropped on the mid-span of the HC member.
 Getting validated by the experimental data, this research also focuses on the development of predictive numerical models for further understanding the mechanical behaviour, section capacities and energy absorption of HC sections. The developed model is used to predict the performance of HC sections with various geometrical parameters. After parametric studies on the HC sections with different corrugation profiles, an explicit formulation is analytically developed to estimate the compressive load carrying and flexural moment capacities of HC sections.
 The results of this research will help engineers to compare the superior performance of HC sections with equivalent fabricated sections and tailor HC sections according to their needs and reach to an optimised configuration. The derived analytical formulation has the potential to be used in the codes of practice for rational analysis and design of HC sections.

Strategy

description: In 2018, AuScope’s Board of Directors initiated a process to develop this Strategy and the accompanying Investment Plan, through a process of deep engagement with our community in academia, government and industry. That engagement has allowed us to understand their research needs better and to define our role in enabling them to advance the Australian geoscience research sector according to national needs. These documents culminate that very productive process. AuScope is a research infrastructure provider, but we are also playing an increasingly important role in science leadership and facilitating research collaboration within our sector. From developing formal links with international geoscience infrastructures, such as the European Plate Observing System (EPOS), to developing standards with Geoscience Australia and other NCRIS organisations including ARDC and NCI, our role has significantly evolved. In developing this Strategy, our community has endorsed this role, and we look forward to pursuing it over the coming decade. This Strategy outlines the approach that AuScope will take to build the Downward Looking Telescope (DLT), a critical infrastructure system identified in the National Research Infrastructure Roadmap, the National Academy of Science’s Decadal Plan
 for Australian Geoscience and most importantly, by the Australian geoscience research community. It also outlines the critical data, culture and collaboration needs surrounding the DLT that will act as the ‘glue’ to enable positively impactful geoscience. When delivered, the DLT will change the way academic, government and industry geoscientists work in Australia, and it is inspiring to be part of that!
description: We would like to acknowledge over 150 people representing the Australian geoscience community for contributing specialist and diverse knowledge to this 10-Year Strategy (Strategy) and the accompanying 5-Year Investment Plan (Investment Plan) during workshops, working groups and discussions between 2018 – 2020.

description: Boson sampling is the problem of generating a quantum bit stream whose average is the permanent of a $n\times n$ matrix. The bitstream is created as the output of a prototype quantum computing device with $n$ input photons. It is a fundamental challenge to verify boson sampling, and the question of how output count rates scale with matrix size $n$ is crucial. Here we apply results from random matrix theory to establish scaling laws for average count rates in boson sampling experiments with arbitrary inputs and losses. The results show that, even with losses included, verification of nonclassical behaviour at large $n$ values is indeed possible.

description: A brief overview of some open questions in general relativity with important consequences for causality theory is presented, aiming to a better understanding of the causal structure of the spacetime. Special attention is accorded to the problem of fundamental causal stability conditions. Several questions are raised and some of the potential consequences of recent results regarding the causality problem in general relativity are presented. A key question is whether causality violating regions are locally allowed. The new concept of almost stable causality is introduced; meanwhile, related conditions and criteria for the stability and almost stability of the causal structure are discussed.

description: Theoretical models of grain growth predict dust properties to change as a function of protoplanetary disk radius, mass, age and other physical conditions. We lay down the methodology for a multi-wavelength analysis of (sub-)mm and cm continuum interferometric observations to constrain self-consistently the disk structure and the radial variation of the dust properties. The computational architecture is massively parallel and highly modular. The analysis is based on the simultaneous fit in the uv-plane of observations at several wavelengths with a model for the disk thermal emission and for the dust opacity. The observed flux density at the different wavelengths is fitted by posing constraints on the disk structure and on the radial variation of the grain size distribution. We apply the analysis to observations of three protoplanetary disks (AS 209, FT Tau, DR Tau) for which a combination of spatially resolved observations in the range ~0.88mm to ~10mm is available (from SMA, CARMA, and VLA), finding evidence of a decreasing maximum dust grain size (a_max) with radius. We derive large a_max values up to 1 cm in the inner disk between 15 and 30 AU and smaller grains with a_max~1 mm in the outer disk (R > 80AU). In this paper we develop a multi-wavelength analysis that will allow this missing quantity to be constrained for statistically relevant samples of disks and to investigate possible correlations with disk or stellar parameters.

The open academic infrastructure and the scientific journal in Venezuela
Creators: name: González Valecillos, Yudith del Carmen
Publisher: name: Zenodo
Year: 2023

description: Latin America maintains an academic infrastructure, which in its great majority belongs to public academic institutions where universities and publishers drive and promote open content through platforms that offer free software, among them, the Universidad Nacional Experimental de los Llanos Occidentales Ezequiel Zamora (Unellez) and operates in the provinces of Apure, Barinas, Cojedes and Portuguesa, being the largest in the western part of Venezuela, The Unellez, has a Journal System, which contains 26 scientific journals of different disciplines. Among them, the Journal of the Latin American Digital Observatory Ezequiel Zamora (Odlez), which has been operating since 2017 and its areas of knowledge are social and political sciences. However, due to the political crisis affecting Venezuela, it shakes all dimensions of the country, and consequently the Educational System. Many will wonder how the academic infrastructure of scientific journals in Venezuela works? From the experience of Odlez, we can express, in terms of governance, this type of project only receives support from the university in the use of an open source free Software platform (Open Journal Systems), which guarantees open standards, data collection, open content, among others. Sustainability is limited by institutional funding, resources are managed autonomously by the national and international editorial team (ad honorem) and consequently the operation depends on the human capital that composes it. There are no government programs or projects that support these initiatives with financial and non-financial resources. This increases the gaps in the open academic infrastructure in the country, since the technology and resources necessary to maintain the sustainability and security of scientific communication in Venezuela are still in use due to the use of open source free software.
Is there a link between organised crime and terrorism in the context of shifting power structures in Eurasia? The Russian Case
Creators: name: Spicer, Jaclyn
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: This study sets out to explore if the nexus between organised crime and terrorism is facilitated by the modern state of Russia. There are four fundamental questions to be considered: What role does the state of Russia play in supporting and enabling organised crime? Is the relationship between state and organised crime purely for ﬁnancial gain or does it achieve political aims of the state? Finally, is it impossible to separate terrorist organisations (TO) and organised crime groups (OCG)? If this is so, is it also impossible to separate these groups from the state that hosts them? The methodology of this study utilises a text analysis to establish the veracity of the link between the Russian state and the use of organised crime as a cheap, deniable tool for state hegemony and hybrid warfare (Marsh 2019, p. 26). The aim of this study is to introduce a conceptual-analytical framework for the study of the nexus between crime, terrorism and state. There is only one case study to be evaluated here, with the view that further empirical studies in the form of social network analysis be undertaken. Caiani (2014), Diviak (2018), and Masys (2014) have raised the need to undertake further research, but their suggested methodologies are vastly diﬀerent and not as suggested here. Social network analysis should be used in conjunction with geo-mapping of organised crime and terrorism trade/logistics routes in Donbass and Crimea at a later date, possibly on an open source intelligence gathering platform similar to Bellingcat1. The use of this methodology has its limitations. Open source intelligence may or may not create overt tension regarding state complicity in the crime/terror nexus. Such complicity for non allies of Australia and the US (such as Russia) may be described by diﬀerent methodologies. OCG and TO show clear convergence and now pose a signiﬁcant security threat to states, including Ukraine (Shaw 2019, pp. 582-584). There is evidence to link OCG with the inner workings of the Kremlin, yet the link between the state of Russia and OCG are often dismissed as being proﬁt motivated and somehow less heinous than state sponsored terrorism, or only described in broad, not individual terms (El Siwi 2018, p. 951; Horgan et al. 2016, pp. 1228-1237). In a rapidly changing global landscape, the new Cold War battlefronts are no longer determined by military prowess, but instead by asymmetrical and non-traditional warfare (Black and Johns 2016, p. 42). Excluding the role of the state and continuing to deﬁne and research OCG and TO based on motivations, deﬁnitions and continuums of activity is limiting (Bobic 2014, p. 242).

description: We present angle-dependent measurements of the effective g-factor g* in a Ge-Si core-shell nanowire quantum dot. g* is found to be maximum when the magnetic field is pointing perpendicular to both the nanowire and the electric field induced by local gates. Alignment of the magnetic field with the electric field reduces g* significantly. g* is almost completely quenched when the magnetic field is aligned with the nanowire axis. These findings confirm recent calculations, where the obtained anisotropy is attributed to a Rashba-type spin-orbit interaction induced by heavy-hole light-hole mixing. In principle, this facilitates manipulation of spin-orbit qubits by means of a continuous high-frequency electric field.

description: The expression of personality pathology differs between people and within a person in day-to-day life. Personality pathology may reflect, in part, dysregulation in basic behavioral processes. Thus, a useful approach for studying maladaptive trait expression comes from literature on stress and daily hassles, which provide dynamic accounts for the relations between individual differences and maladaptive dysregulation. This study sought to integrate maladaptive traits and dynamic stress processes to further dynamic models of personality pathology. In a combined clinical/community sample (N=297) oversampled for interpersonal problems, we used ecological momentary assessment (observation N=19,968) to investigate how maladaptive traits moderated the processes of stress generation, stress reactivity, and affective spillover/inertia. Tests of our preregistered hypotheses provided a mix of supportive and null findings for stress processes identified in past research, and mixed support for the moderating role of personality. The results provide insights into the relations between everyday stressors and personality pathology.

description: A prática drag queen diz respeito a um processo de adequação que desloca a aparência corriqueira de uma pessoa para uma outra que pode transitar entre gêneros (masculino, feminino, polimorfo, diversos) e espécies (humano e animal, como é o caso de drags que se apresentam como animais e até alienígenas). O presente trabalho tem por objetivo observar e participar dessa prática na cidade de Fortaleza – CE com intuito de absorver seus processos de criação, adaptação, montagem e desmontagem. Entender as mutações as quais essa prática está sujeita, as influências externas e a capacidade de adaptação das drag queens estudadas. Usar lentes analíticas que possibilitem enxergar as práticas através de uma epistemologia da performance que leve em consideração a decolonização do pensamento e a apreensão crítica da tradição científica europeia. O estudo se configura por meio de uma experiência etnográfica embasada no exercício da descrição densa e de entrevistas pontuais. Os registros foram feitos mediante diário de campo, fotografias, vídeos e gravador de voz. Concluiu-se que a prática drag queen na cidade de Fortaleza – CE passou e passa por mudanças constantes no que diz respeito à tradição e ao surgimento de novas formas de fazer drag. Formas essas impactadas pelo reality show americano RuPaul’s Drag Race e sua tendência de transformação da drag queen em um produto passível de ser comercializado mundialmente através da TV. Observou-se ainda que, ademais da forte influência trazida por esse reality show, o contexto local tem se mostrado resistente às tentativas de suplantação da tradição, tendo como elementos de resistência o bate- cabelo e o dialeto yorubá que se contrapõem à força histórica de opressão conhecida como colonização.

Lorentz atom revisited by solving Abraham-Lorentz equation of motion

description: By solving the non-relativistic Abraham-Lorentz (AL) equation, I demonstrate that AL equation of motion is not suited for treating the Lorentz atom, because a steady-state solution does not exist. The AL equation serves as a tool, however, for deducing appropriate parameters $Ω,Γ$ to be used with the equation of forced oscillations in modelling the Lorentz atom. The electric polarizability, which many authors "derived" from AL equation in recent years, is found to violate Kramers-Kronig relations rendering obsolete the extracted photon-absorption rate, for example. Fortunately, errors turn out to be small quantitatively, as long as light frequency $ω$ is neither too close to nor too far from resonance frequency $Ω$. Polarizability and absorption cross section are derived for the Lorentz atom by purely classical reasoning and shown to agree with quantum-mechanical calculations of the same quantities. In particular, oscillator parameters $Ω,\,Γ$ deduced by treating the atom as a quantum oscillator are found equivalent to those derived from classical AL equation. The instructive comparison provides a deep insight into understanding the great success of Lorentz's model which was suggested long before the advent of quantum theory.

description: Policy support for urban agriculture (UA) has increased internationally in the past decade, driven by factors such as urban decay, food insecurity, climate change and disasters, self-determination efforts and the Covid-19 pandemic. To date, there has been little analysis of the emergent practices across different cities in Aotearoa New Zealand. To address this gap, we examine key aspects of UA in Aotearoa and assess the application of local plans and regulation to determine how UA is defined and treated in the four most populous cities. The results reveal a lack of specific attention to and policy direction for UA. This vacuum is compounded by purpose-driven zoning typologies, restrictive resource use controls, scant provision for Māori food practices and a failure to keep pace with the changing forms of UA. The results identify the need for cities to review and clarify provision for UA, to create greater certainty and where appropriate, facilitation of food sovereignty and diverse urban foodscapes.

description: Two-, three-, and four-boson systems are studied close to the unitary limit using potential models constructed to reproduce the minimal information given by the two-body scattering length $a$ and the two-body binding energy or virtual state energy $E_2$. The particular path used to reach the unitary limit is given by varying the potential strength. In this way the energy spectrum in the three- and four-boson systems is computed. The lowest energy states show finite-range effects absorbed in the construction of level functions that can be used to study real systems. Higher energy levels are free from finite-range effects, therefore the corresponding level functions tend to the zero-range universal function. Using this property a zero-range equation for the four-boson system is proposed and the four-boson universal function is computed.

The Value and Challenges of Student-Run Journals: Lessons from a Student Editor
Creators: name: Lujano, Ivonne
Publisher: name: Zenodo
Year: 2023

description: Student-run journals are unique spaces for learning about and engaging with the scholarly publication landscape. Student editors and reviewers build their authorial voice and academic identity by leading the editorial process, which may help increase their sense of belonging to academia. Moreover, student journals serve diverse communities and are particularly committed to open access. Indeed, many existing student journals are run under the diamond model as universities host and support their operations. Despite the outlined benefits, there are several challenges when running a student journal. For instance, student journals may be considered few relevant as they are perceived as less prestigious and reputable than the so-called ‘top tier’ journals. This perception might result in lacking institutional or financial support. In this talk, I will share the lessons learned from my experience as a student editor of Current Issues in Education, a diamond open-access journal sponsored by Arizona State University. I will highlight the opportunities I encountered as a doctoral student to actively engage in discussions about topics, methods, and approaches in educational research. Finally, I will present my arguments to increase the support for student-run journals as they are spaces for innovation and recognition of the epistemic value of OA journals beyond commercial interests.

description: The Dirac-like quasiparticles in honeycomb graphene lattice are taken to possess a non-zero effective mass. The charge carriers involve to interact with a femtosecond strong laser pulse. Due to the scattering time of electrons in graphene ($τ\approx 10-100 fs$), the one femtosecond optical pulse is used to have coherence effect, and consequently, it is realized to use the time-dependent Schr$\ddot{o}$dinger equation for coupling electron with strong electromagnetic field. Generalized wavevector of relativistic electrons interacting with electric field of laser pulse leads to obtain a time-dependent electric dipole matrix element. Using the coupled differential equations of a two-state system of graphene, the density of probability of population transition between valence and conduction bands of gapped graphene is calculated. In particular, the effect of bandgap energy on dipole matrix elements in the Dirac points, and also on conduction band population is investigated. The irreversible electron dynamics is achieved when the optical pulse end. Increasing the energy gap of graphene results in a decreasing the maximum conduction band population.
