description: Given two metastable states A and B of a biomolecular system, the problem is to calculate the likely paths of the transition from A to B. Such a calculation is more informative and more manageable if done for a reduced set of collective variables chosen so that paths cluster in collective variable space. The computational task becomes that of computing the "center" of such a cluster. A good way to define the center employs the concept of a committor, whose value at a point in collective variable space is the probability that a trajectory at that point will reach B before A. The committor "foliates" the transition region into a set of isocommittors. The maximum flux transition path is defined as a path that crosses each isocommittor at a point which (locally) has the highest crossing rate of distinct reactive trajectories. (This path is different from that of the MaxFlux method of Huo and Straub.) It is argued that such a path is nearer to an ideal path than others that have been proposed with the possible exception of the finite-temperature string method path. To make the calculation tractable, three approximations are introduced, yielding a path that is the solution of a nonsingular two-point boundary-value problem. For such a problem, one can construct a simple and robust algorithm. One such algorithm and its performance is discussed.

description: Widely distributed misinformation shared across social media channels is a pressing issue that poses a significant threat to many aspects of society's well-being. Inaccurate shared information causes confusion, can adversely affect mental health, and can lead to mis-informed decision-making. Therefore, it is important to implement proactive measures to intervene and curb the spread of misinformation where possible. This has prompted scholars to investigate a variety of intervention strategies for misinformation sharing on social media. This study explores the typology of intervention strategies for addressing misinformation sharing on social media, identifying 4 important clusters - cognition-based, automated-based, information-based, and hybrid-based. The literature selection process utilized the PRISMA method to ensure a systematic and comprehensive analysis of relevant literature while maintaining transparency and reproducibility. A total of 139 articles published from 2013-2023 were then analyzed. Meanwhile, bibliometric analyses were conducted using performance analysis and science mapping techniques for the typology development. A comparative analysis of the typology was conducted to reveal patterns and evolution in the field. This provides valuable insights for both theory and practical applications. Overall, the study concludes that scholarly contributions to scientific research and publication help to address research gaps and expand knowledge in this field. Understanding the evolution of intervention strategies for misinformation sharing on social media can support future research that contributes to the development of more effective and sustainable solutions to this persistent problem.

description: The non-scientific event of a soccer match is analysed on a strictly scientific level. The analysis is based on the recently introduced concept of a team fitness (Eur. Phys. J. B 67, 445, 2009) and requires the use of finite-size scaling. A uniquely defined function is derived which quantitatively predicts the expected average outcome of a soccer match in terms of the fitness of both teams. It is checked whether temporary fitness fluctuations of a team hamper the predictability of a soccer match. To a very good approximation scoring goals during a match can be characterized as independent Poissonian processes with pre-determined expectation values. Minor correlations give rise to an increase of the number of draws. The non-Poissonian overall goal distribution is just a consequence of the fitness distribution among different teams. The limits of predictability of soccer matches are quantified. Our model-free classification of the underlying ingredients determining the outcome of soccer matches can be generalized to different types of sports events.

description: Developmental and epileptic encephalopathies (DEEs) are a group of rare childhood disorders characterized by severe epilepsy and cognitive deficits. Numerous DEE genes have been discovered thanks to advances in genomic diagnosis, yet putative molecular links between these disorders are unknown. CDKL5 deficiency disorder (CDD, DEE2), one of the most common genetic epilepsies, is caused by loss-of-function mutations in the brain-enriched kinase CDKL5. To elucidate CDKL5 function, we looked for CDKL5 substrates using a SILAC-based phosphoproteomic screen. We identified the voltage-gated Ca2+ channel Cav2.3 (encoded by CACNA1E) as a physiological target of CDKL5 in mice and humans. Recombinant channel electrophysiology and interdisciplinary characterization of Cav2.3 phosphomutant mice revealed that loss of Cav2.3 phosphorylation leads to channel gain-of-function via slower inactivation and enhanced cholinergic stimulation, resulting in increased neuronal excitability. Our results thus show that CDD is partly a channelopathy. The properties of unphosphorylated Cav2.3 closely resemble those described for CACNA1E gain-of-function mutations causing DEE69, a disorder sharing clinical features with CDD. We show that these two single-gene diseases are mechanistically related and could be ameliorated with Cav2.3 inhibitors.

description: We report nanoscale patterning of graphene using a helium ion microscope configured for lithography. Helium ion lithography is a direct-write lithography process, comparable to conventional focused ion beam patterning, with no resist or other material contacting the sample surface. In the present application, graphene samples on Si/SiO2 substrates are cut using helium ions, with computer controlled alignment, patterning, and exposure. Once suitable beam doses are determined, sharp edge profiles and clean etching are obtained, with little evident damage or doping to the sample. This technique provides fast lithography compatible with graphene, with ~15 nm feature sizes.
Exercise haemodynamics : physiology and clinical consequences
Creators: name: Schultz, MG
Publisher: name: University Of Tasmania

description: High blood pressure (BP) is a leading risk factor for premature death relating to cardiovascular (CV) disease. Some individuals with normal resting BP may experience an excessive rise in BP with exercise; a condition termed 'hypertensive response to exercise' (HRE). Despite having normal resting BP, an HRE has been implicated in contributing to CV risk, but little is known on the condition. The broad aims of this research program were to determine; the prognostic and clinical significance of an HRE; the efficacy of a lifestyle intervention program to 'treat' an HRE and; the haemodynamic mechanisms contributing to exercise BP. In study 1 (chapter 2), the prognostic value of an HRE for predicting CV events and mortality was examined via systematic review and meta-analysis on data from 12 studies (46,314 individuals). Elevated BP at moderate intensity exercise predicted CV events and mortality, independent of resting BP, age and multiple CV risk factors (HR=1.36, 95% CI: 1.02-1.83, P=0.039). Study 2 (chapter 3) sought to determine a possible explanation as to why an HRE was associated with increased CV risk. In a cohort of 77 individuals with an HRE, a high prevalence (56%) of masked hypertension was observed. Moreover, moderate exercise systolic BP >190 mmHg revealed the presence of masked hypertension with high positive predictive value (94% sensitivity, P<0.001). In study 3 (chapter 4), the effects of a one-year lifestyle (exercise and diet) intervention on exercise BP was examined in 185 individuals with type 2 diabetes mellitus. An HRE was not significantly reduced by the intervention. However, development of an HRE was preventable in those individuals without an HRE at baseline (P=0.020). In study 4 (chapter 5), the haemodynamic mechanisms of exercise central BP were examined in 10 individuals undergoing coronary angiography. Exercise BP was principally related to increases in forward wave propagation generated by left-ventricular ejection, whereas mathematically-derived aortic reservoir function was unchanged with exercise. This mechanistic work was extended in study 5 (chapter 6), where aortic reservoir pressure was directly measured for the first time in 10 individuals undergoing coronary bypass surgery. Directly-measured and mathematically-derived aortic reservoir pressures were highly related, thus providing evidence for an 'aortic reservoir function' in generation of central BP. In summary, this research shows that an HRE is related to increased CV risk, and this may be due to masked hypertension. Furthermore, it was possible to attenuate progression towards an HRE with lifestyle intervention. Finally, exercise BP was found to be predominantly due to forward wave transmission, and mathematically-derived aortic reservoir pressure is a valid construct relevant to understanding the physiology of central BP.

description: We determine the prospects for finding dark matter at the Tevatron and LHC through the production of exotic 4th generation quarks T' that decay through T' \to t X, where X is dark matter. The resulting signal of t \bar{t} + \met has not previously been considered in searches for 4th generation quarks, but there are both general and specific dark matter motivations for this signal, and with slight modifications, this analysis applies to any scenario where invisible particles are produced in association with top quarks. Current direct and indirect bounds on such exotic quarks restrict their masses to be between 300 and 600 GeV, and the dark matter's mass may be anywhere below m_T'. We simulate the signal and main backgrounds with MadGraph/MadEvent-Pythia-PGS4. For the Tevatron, we find that an integrated luminosity of 20 fb^-1 will allow 3σdiscovery up to m_T' = 400 GeV and 95% exclusion up to m_T' = 455 GeV. For the 10 TeV LHC with 300 pb^-1, the discovery and exclusion sensitivities rise to 490 GeV and 600 GeV. These scenarios are therefore among the most promising for dark matter at colliders. Perhaps most interestingly, we find that dark matter models that can explain results from the DAMA, CDMS and CoGeNT Collaborations can be tested with high statistical significance using data already collected at the Tevatron and have extraordinarily promising implications for early runs of the LHC.

Proteomics analysis for Barrett's Oesophagus biopsies and oesophageal lesions in HPV infected individuals
Creators: name: Obaid, N
Publisher: name: University Of Tasmania
Year: 2023

description: Oesophageal lesions caused by HPV are known recently as a contributor to oesophageal squamous cell carcinoma. Some evidences show that these lesions in association with Barrett's oesophagus can progress to oesophageal adenocarcinoma. In addition, these lesions are considered to be precancerous or thought to have a role in progression to cancer by a synergistic effect. Aims: To identify proteins that are related to pathological lesions of the oesophagus (Barrett's oesophagus and oesophageal HPV lesion) by using proteomic analysis. Methods: Four oesophageal biopsies were taken from patients with Barrett's oesophagus, HPV lesions and oesophagitis. Two biopsies were previously confirmed to have HPV lesions using a PCR technique. Proteomics analysis was undertaken by LC/MS/MS using the MudPIT technique. Results: Two comparison groups of the samples were generated to perform a quantitative analysis for this proteomics approach. The first comparison was between Barrett's oesophagus with HPV and Barrett's oesophagus without HPV. Eleven proteins in this group showed significant association with diseases, including cancers. In addition, one protein was identified previously as a Barrett's oesophagus marker. The second comparison was between an oesophageal HPV lesion and an oesophagitis sample. Five proteins showed potential significance in relation to cancers. Conclusion: HPV lesions have over expression of proteins that are related to neoplasia when HPV is associated with Barrett's oesophagus. This generates a hypothesis: HPV infection of the oesophagus could not affect protein expression unless associated with Barrett's oesophagus. Many questions have arisen and need further investigation.

description: We study exact solutions to Cosmological Topologically Massive Gravity (CTMG) coupled to Topologically Massive Electrodynamics (TME) at special values of the coupling constants. For the particular case of the so called chiral point lμ_G=1, vacuum solutions (with vanishing gauge field) are exhibited. These correspond to a one-parameter deformation of GR solutions, and are continuously connected to the extremal Bañados-Teitelboim-Zanelli black hole (BTZ) with bare constants J=-lM. At the chiral point this extremal BTZ turns out to be massless, and thus it can be regarded as a kind of ground state. Although the solution is not asymptotically AdS_3 in the sense of Brown-Henneaux boundary conditions, it does obey the weakened asymptotic recently proposed by Grumiller and Johansson. Consequently, we discuss the holographic computation of the conserved charges in terms of the stress-tensor in the boundary. For the case where the coupling constants satisfy the relation lμ_G=1+2lμ_E, electrically charged analogues to these solutions exist. These solutions are asymptotically AdS_3 in the strongest sense, and correspond to a logarithmic branch of selfdual solutions previously discussed in the literature.

Computational Inverse Problems for Partial Differential Equations (hybrid meeting)

Subjects: subject: Konferenzschrift
subject: 510

description: Inverse problems in partial differential equations (PDEs) consist in reconstructing some part of a PDE such as a coefficient, a boundary condition, an initial condition, the shape of a domain, or a singularity from partial knowledge of solutions to the PDE. This has numerous applications in nondestructive testing, medical imaging, seismology, and optical imaging. Whereas classically mostly boundary or far field data of solutions to deterministic PDEs were considered, more recently also statistical properties of solutions to random PDEs have been studied. The study of numerical reconstruction methods of inverse problems in PDEs is at the interface of numerical analysis, PDE theory, functional analysis, statistics, optimization, and differential geometry. This workshop has mainly addressed five related topics of current interest: model reduction, control-based techniques in inverse problems, imaging with correlation data of waves, fractional diffusion, and model-based approaches using machine learning.

description: Understanding the molecular content of galaxies is a critical problem in star formation and galactic evolution. Here we present a new method, based on a Stromgren-type analysis, to calculate the amount of HI that surrounds a molecular cloud irradiated by an isotropic radiation field. We consider both planar and spherical clouds, and H_2 formation either in the gas phase or catalyzed by dust grains. Under the assumption that the transition from atomic to molecular gas is sharp, our method gives the solution without any reference to the photodissociation cross section. We test our results for the planar case against those of a PDR code, and find typical accuracies of about 10%. Our results are also consistent with the scaling relations found in Paper I of this series, but they apply to a wider range of physical conditions. We present simple, accurate analytic fits to our results that are suitable for comparison to observations and to implementation in numerical and semi-analytic models.

description: Theory and application go hand in hand in most areas of statistics. In a world flooded with huge amounts of data waiting to be analyzed, classified and transformed into useful outputs, the designing of fast, robust and stable algorithms has never been as important as it is today. On the other hand, irrespective of whether the focus is put on estimation, prediction, classification or other purposes, it is equally crucial to provide clear guarantees that such algorithms have strong theoretical guarantees. Many statisticians, independently of their original research interests, have become increasingly aware of the importance of the numerical needs faced in numerous applications including gene expression profiling, health care, pattern and speech recognition, data security, marketing personalization, natural language processing, to name just a few. The goal of this workshop is twofold: (a) exchange knowledge on successful algorithmic approaches and discuss some of the existing challenges, and (b) to bring together researchers in statistics and machine learning with the aim of sharing expertise and exploiting possible differences in points of views to obtain a better understanding of some of the common important problems.

Land exploration in Tasmania, 1824- 1842: With special reference to the Van Diemen's Land Company
Creators: name: Franks, SM
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis does not purport to be a comprehensive, definitive account of all Tasmanian exploration undertaken during the years from 1824 to 1842. Much of the exploration that was carried out during this (and other) periods was obviously not undertaken in that name, but was merely the incidental result of activities with another purpose: hunters roaming away from the settlement; settlers seeking for new lands; stockmen searching for lost cattle or sheep; or escaped convicts seeking freedom in the uninhabited and unknown wilds of the Colony. Of moat of these journeys no official or non-official record now remains, or probably ever existed; for, even if they had been disposed to write down their experiences, undoubtedly a great many of these bush travellers were illiterate. In other cases, where some record does survive, the people concerned were only semi-literate, and ill equipped to make a geographically intelligible report of their journeys. For this reason, the limited availability of records, this thesis deals mainly with exploration tmdertaken in an official or semi-official capacity by Government or privately sponsored surveyors; or by settlers possessing the requisite knowledge to give accurate reports of the country they traversed.
Applications of Optimal Transportation in the Natural Sciences (online meeting)

Subjects: subject: Konferenzschrift
subject: 510

description: Concepts and methods from the mathematical theory of optimal transportation have reached significant importance in various fields of the natural sciences. The view on classical problems from a "transport perspective'' has lead to the development of powerful problem-adapted mathematical tools, and sometimes to a novel geometric understanding of the matter. The natural sciences, in turn, are the most important source of ideas for the further development of the optimal transport theory, and are a driving force for the design of efficient and reliable numerical methods to approximate Wasserstein distances and the like. The presentations and discussions in this workshop have been centered around recent analytical results and numerical methods in the field of optimal transportation that have been motivated by specific applications in statistical physics, quantum mechanics, and chemistry.

description: We study the production of prompt diphotons in the central region of rapidity within the framework of the quasi-multi-Regge-kinematics approach applying the hypothesis of quark and gluon Reggeization. We describe accurately and without free parameters the experimental data which were obtained by the CDF Collaboration at the Tevatron Collider. It is shown that the main contribution to studied process is given by the direct fusion of two Reggeized gluons into a photon pair, which is described by the effective Reggeon-Reggeon to particle-particle vertex. The contribution from the annihilation of Reggeized quark-antiquark pair into a diphoton is also considered. At the stage of numerical calculations we use the Kimber-Martin-Ryskin prescription for unintegrated quark and gluon distribution functions, with the Martin-Roberts-Stirling-Thorne collinear parton densities for a proton as input.

description: The forces acting on an optically trapped particle are usually assumed to be conservative. However, the presence of a non-conservative component has recently been demonstrated. Here we propose a technique that permits one to quantify the contribution of such non-conservative component. This is an extension of a standard optical tweezers calibration technique and, therefore, can easily become a standard test to verify the conservative optical force assumption. Using this technique we have analyzed different-sized optically trapped particles under different trapping conditions. We conclude that the non-conservative effects are effectively negligible and do not affect the standard calibration procedure, unless for extremely low-power trapping, far away from the trapping regimes usually used in experiments.

Memory's Image
Creators: name: Frost, RE
Publisher: name: University Of Tasmania
Year: 2023

description: How can the process of memory be represented in visual terms? This project investigated the nature of autobiographical or recollective memoryusing photographically derived, computer environments as a visual art form; and is based on some of the wealth of material written about 'memory' or 'memories' and recollection. My aim was to consider this material and use it as a basis for generating work that visually explored the attributes of memory; that evoked the sensation of remembering one's past and, in particular, memories of childhood. In researching the experience of recollective memory I identified the memory image as pivotal. In brief, I proposed that central to the experience of remembering is the occurrence of a memory image. But when people say, 'I remember,' what are they actually seeing? Is there a visual language of memory that is shared by us all? How might we see memory in our mind's eye? Secondly, what is the nature of this encounter? Could this experience be described as interactive? Would some form of interactivity be a useful addition to the work? In considering the issue of interactivity as a viable option for the experience of remembering, I was to find firstly, that the process is primarily reactive whether undertaken voluntarily or involuntarily - a cue provokes and we react Secondly, the interactive element I had questioned was vastly different to that which I had originally conceived. Instead of a trigger for an image it was an engagement with the image. Rather than being the cause of an action, the interactivity comes as we embroider and place it in a context We weave the fragments together to tell a story. Interestingly, as I reviewed the visual characteristics of the memory image I found no clear demarcation. It appeared to be highly subjective, with comments ranging from unclear, little or no color and hazy, to highly detailed and vivid. In a similar manner the size and position of the image in space varied. The most important element for me was the notion of these images as small fragments of experience rather then complete episodes in themselves. In resolving how to evoke an experience of remembering, my work shifted from a screen-based CD-ROM style presentation to video installation. I moved from the use of still photographs to the utilization of full screen digital video as I struggled to represent the memory image in a dynamic rather than static form - as remnants of lived experience rather than frozen instances of time. The thesis exhibition presents the viewer with these fragments. Interaction is present less in the triggering of the memory than in the associations - in the narrative that is constructed and woven from remnants. Although the imagery does, at times, reference glimpses from my own childhood, I have also been concerned to evoke a more generic representation of the memory image. It is my hope that this project will contribute to an understanding of the visual nature of the memory image and its role in the experience of remembering.
Homotopic and Geometric Galois Theory (online meeting)

description: In his "Letter to Faltings'', Grothendieck lays the foundation of what will become part of his multi-faceted legacy to arithmetic geometry. This includes the following three branches discussed in the workshop: the arithmetic of Galois covers, the theory of motives and the theory of anabelian Galois representations. Their geometrical paradigms endow similar but complementary arithmetic insights for the study of the absolute Galois group $\mathrm{G}_{\mathbb{Q}}$ of the field of rational numbers that initially crystallized into a functorially group-theoretic unifying approach. Recent years have seen some new enrichments based on modern geometrical constructions - e.g. simplicial homotopy, Tannaka perversity, automorphic forms - that endow some higher considerations and outline new geometric principles. This workshop brought together an international panel of young and senior experts of arithmetic geometry who sketched the future desire paths of homotopic and geometric Galois theory.

description: Direct detection experiments have reached the sensitivity required to detect dark matter WIMPs. Demonstrating that a putative signal is due to WIMPs, and not backgrounds, is a major challenge however. The direction dependence of the WIMP scattering rate provides a potential WIMP `smoking gun'. If the WIMP distribution is predominantly smooth, the Galactic recoil distribution is peaked in the direction opposite to the direction of Solar motion. Previous studies have found that, for an ideal detector, of order 10 WIMP events would be sufficient to reject isotropy, and rule out an isotropic background. We examine how the median recoil direction could be used to confirm the WIMP origin of an anisotropic recoil signal. Specifically we determine the number of events required to reject the null hypothesis that the median direction is random (corresponding to an isotropic Galactic recoil distribution) at 95% confidence. We find that for zero background 31 events are required, a factor of roughly 2 more than are required to simply reject isotropy. We also investigate the effect of a non-zero isotropic background. As the background rate is increased the number of events required increases, initially fairly gradually and then more rapidly, once the signal becomes subdominant. We also discuss the effect of features in the speed distribution at large speeds, as found in recent high resolution simulations, on the median recoil direction.

description: Machine learning and in particular deep learning offer several data-driven methods to amend the typical shortcomings of purely analytical approaches. The mathematical research on these combined models is presently exploding on the experimental side but still lacking on the theoretical point of view. This workshop addresses the challenge of developing a solid mathematical theory for analyzing deep neural networks for inverse problems.

subject: FOS: Physical sciences

description: We develop a simple theoretical framework for the evolution of weighted networks that is consistent with a number of stylized features of real-world data. In our framework, the Barabasi-Albert model of network evolution is extended by assuming that link weights evolve according to a geometric Brownian motion. Our model is verified by means of simulations and real world trade data. We show that the model correctly predicts the intensity and growth distribution of links, the size-variance relationships of the growth of link weights, the relationship between the degree and strength of nodes, as well as the scale-free structure of the network.
Nutritional and time of harvesting studies of the poppy (Papaver somniferum L.) on krasnozem soils of Tasmania: nutritional and time of harvesting studies of Papaver somniferum L.
Creators: name: Laughlin, JC
Publisher: name: University Of Tasmania
Year: 2023

description: The effects of banded nitrogen and phosphorus fertilizer on the growth of poppies on a krasnozem soil were studied at three different stages of growth; (i) young plants fifty days after sowing, (ii) mature capsules at dry commercial maturity eight weeks after full bloom, (iii) total plant and its components harvested at weekly intervals between full bloom and dry commercial maturity. Higher uptake of banded P and greater plant dry matter yield 50 days after sowing were recorded when the fertilizer was placed 40 mm directly below the seed than when placed 75 mm below. Nitrogen had a negative effect on both uptake and yield in this experiment.

description: We report on the etching of graphene devices with a helium ion beam, including in situ electrical measurement during lithography. The etching process can be used to nanostructure and electrically isolate different regions in a graphene device, as demonstrated by etching a channel in a suspended graphene device with etched gaps down to about 10 nm. Graphene devices on silicon dioxide (SiO2) substrates etch with lower He ion doses and are found to have a residual conductivity after etching, which we attribute to contamination by hydrocarbons.

description: The expanded level structure of $^{240}$Pu available from the present study highlights the role of strong octupole correlations in this nucleus. Besides a delayed alignment in the yrast band, the observations include the presence of both $I^{+}{\to}(I-1)^{-}$ and $I^{-}{\to}(I-1)^{+}$ E1 transitions linking states of the yrast and negative-parity bands at high spin and the presence of an additional even-spin, positive-parity band deexciting exclusively to the negative parity sequence. The observations appear to be consistent with expectations based on the recently proposed concept of octupole phonon condensation.

Mathematical Foundations of Machine Learning (hybrid meeting)

Publisher: name: Zürich : EMS Publ. House
Year: 2021
Subjects: subject: Konferenzschrift
subject: 510

description: Machine learning has achieved remarkable successes in various applications, but there is wide agreement that a mathematical theory for deep learning is missing. Recently, some first mathematical results have been derived in different areas such as mathematical statistics and statistical learning. Any mathematical theory of machine learning will have to combine tools from different fields such as nonparametric statistics, high-dimensional statistics, empirical process theory and approximation theory. The main objective of the workshop was to bring together leading researchers contributing to the mathematics of machine learning. A focus of the workshop was on theory for deep neural networks. Mathematically speaking, neural networks define function classes with a rich mathematical structure that are extremely difficult to analyze because of non-linearity in the parameters. Until very recently, most existing theoretical results could not cope with many of the distinctive characteristics of deep networks such as multiple hidden layers or the ReLU activation function. Other topics of the workshop are procedures for quantifying the uncertainty of machine learning methods and the mathematics of data privacy.

description: Quasi-constant external fields in nonlinear electromagnetism generate a contribution to the energy-momentum tensor with the form of dark energy. To provide a thorough understanding of the origin and strength of the effects, we undertake a complete theoretical and numerical study of the energy-momentum tensor $T^{μν}$ for nonlinear electromagnetism. The Euler-Heisenberg nonlinearity due to quantum fluctuations of spinor and scalar matter fields is considered and contrasted with the properties of classical nonlinear Born-Infeld electromagnetism. We also address modifications of charged particle kinematics by strong background fields.

Small Collaboration: Numerical Analysis of Electromagnetic Problems (hybrid meeting)
Creators: name: (:Unkn) Unknown
Publisher: name: Zürich : EMS Publ. House
Year: 2021
Subjects: subject: Konferenzschrift
subject: 510

description: The classical theory of electromagnetism describes the interaction of electrically charged particles through electromagnetic forces, which are carried by the electric and magnetic fields. The propagation of the electromagnetic fields can be described by Maxwell's equations. Solving Maxwell's equations numerically is a challenging problem which appears in many different technical applications. Difficulties arise for instance from material interfaces or if the geometrical features are much larger than or much smaller than a typical wavelength. The spatial discretization needs to combine good geometrical flexibility with a relatively high order of accuracy. The aim of this small-scale, week-long interactive mini-workshop jointly organized by the University of Duisburg-Essen and the University of Twente, and kindly hosted at the MFO, is to bring together experts in non-standard and mixed finite elements methods with experts in the field of electromagnetism.
