description: Speakers of non-English languages often adopt loanwords from English to express new or unusual concepts. While these loanwords may be borrowed unchanged, speakers may also integrate the words to fit the constraints of their native language, e.g. creating Spanish "tuitear" from English "tweet." Linguists have often considered the process of loanword integration to be more dependent on language-internal constraints, but sociolinguistic constraints such as speaker background remain only qualitatively understood. We investigate the role of social context and speaker background in Spanish speakers' use of integrated loanwords on social media. We find first that newspaper authors use the integrated forms of loanwords and native words more often than social media authors, showing that integration is associated with formal domains. In social media, we find that speaker background and expectations of formality explain loanword and native word integration, such that authors who use more Spanish and who write to a wider audience tend to use integrated verb forms more often. This study shows that loanword integration reflects not only language-internal constraints but also social expectations that vary by conversation and speaker.
RHESSI observation of flare elements

description: RHESSI observations of elementary flare bursts are presented. These solar flare elements are distinct emission peaks of a duration of some tens of seconds present in the hard X-ray light curves. They are characterized by consistent soft-hard-soft spectral behavior, which can be described in a quantitative way and compared which predictions from acceleration models. A detailed analysis of hard X-ray images for an M5 class flare shows that elementary flare bursts do not occur at distinct locations, but as twin X-ray sources move smoothly along an arcade of magnetic loops. This observation apparently contradicts the predictions of standard translation invariant 2.5-dimensional reconnection models.

description: David Hockney is a leading figure in contemporary printmaking. Since 1954 making prints has been an integral part of Hockney's art practice. It is a field of art in which he is truly gifted and, over five decades, he has created a significant body of prints. He has constantly pushed the boundaries of printmaking in terms of style, subject matter and technique. This is almost without parallel in recent art history. Printmaking has also provided Hockney with a diversion when other forms of his art, notably painting, were in a stylistic and iconographic cul de sac. The history of Hockney's involvement in making prints has formed a critical path in his overall artistic development in all its variety of forms. For much of his life as an artist, David Hockney has been freer, more experimental and less inhibited in his approach to creating art, when making prints than when painting. A successful career in painting often eluded him during much of his early career particularly after he adopted the use of acrylic paint and Hockney would often find himself in an artistic dead end in his painting style. In contrast, making prints often provided a way forward for Hockney. This modus operandi continued for much of his artistic life until his more recent embrace of digital processes in art using an iPhone or iPad. Hockney's development from an emerging artist to a mature and successful one lay in his constant searching for new ways of depiction, other than those belonging to new modernist canons. He was constantly posing pictorial problems and then trying to solve them. To this end, Hockney developed a hybrid art in his printmaking, one of wide ranging eclecticism. He then turned to naturalism, only to find he needed to explore further choices. As a mature artist Hockney achieved a fusion of the abstract and formal elements in his work and to tackle age-old issues - how to portray someone, how to depict a landscape and a season, a time of day and under certain weather conditions and how to indicate space and time in two-dimensional art form. For Hockney, printmaking has been an integral part of this search and discovery. Now entering the second decade of the 21st century, Hockney has finally achieved his ambition to become a landscape painter of consequence and now the focus for Hockney lies there. The significant purpose and role that prints played in his artistic career in the twentieth century have ceased to exist - at least for the present. -- provided by Candidate.

description: We consider Weyl gauge theories of gravity (WGTs), which are invariant both under local Poincaré transformations and local changes of scale. Such theories may be interpreted as gauge theories in Minkowski spacetime, but their gravitational interactions are most often reinterpreted geometrically in terms of a Weyl--Cartan spacetime, in which any matter fields then reside. Such a spacetime is a straightforward generalisation of Weyl spacetime to include torsion. As first suggested by Einstein, Weyl spacetime is believed to exhibit a so-called second clock effect, which prevents the existence of experimentally observed sharp spectral lines, since the rates of (atomic) clocks depend on their past history. The prevailing view in the literature is that this rules out WGTs as unphysical. Contrary to this viewpoint, we show that if one adopts the natural covariant derivative identified in the geometric interpretation of WGTs, properly takes into account the scaling dimension of physical quantities, and recognises that Einstein's original objection requires the presence of massive matter fields to represent atoms, observers and clocks, then WGTs do not predict a second clock effect.

description: Die Photovoltaik spielt eine zentrale Rolle bei der Transformation des globalen Energiesystems zu einer emissionsfreien Energieversorgung. In Deutschland tragen rund 1,8 Millionen installierte Photovoltaikdachanlagen mit einer Nennleistung bis zu 30 kWp zur elektrischen Energieerzeugung bei. Dennoch zeigt sich insbesondere in dieser Anlagenklasse, dass durch eine fehlende Fernüberwachung der Stromproduktion und ein fehlendes Qualitätssicherungskonzept technische Störungen auftreten können und es damit zu einer Minderung des Ertrags dieser Photovoltaikanlagen kommt [HHR18; HHR19; SH21]. Bislang wurden zur Erkennung von solchen Anomalien manuelle Verfahren verwendet; Machine-Learning-Konzepte können eine automatisierte und adaptive Alternative darstellen. Hierfür wird die Implementierung eines Isolation Forests mit dem Ansatz von Leloux [Le20] hinsichtlich des methodischen Aufbaus verglichen. Zur Bewertung der verschiedenen Ergebnisse werden exemplarische Ertragsdaten von einzelnen Anlagen analysiert. Der vorliegende Datensatz besteht aus den jeweiligen Erträgen der Anlagen in fünfminütigen Intervallen sowie den nötigen Stammdaten von Photovoltaikanlagen im Südwesten Deutschlands. Die Gegenüberstellung der Verfahren zeigt, dass die Anomalieerkennung durch Isolation Forests Betriebsstörungen von Photovoltaikanlagen automatisch identifizieren kann.

description: In this paper we provide some circumstantial evidence for a holographic duality between bubble nucleation in an eternally inflating universe and a Euclidean conformal field theory. The holographic correspondence (which is different than Strominger's dS/CFT duality) relates the decay of (3+1)-dimensional de Sitter space to a two-dimensional CFT. It is not associated with pure de Sitter space, but rather with Coleman-De Luccia bubble nucleation. Alternatively, it can be thought of as a holographic description of the open, infinite, FRW cosmology that results from such a bubble. The conjectured holographic representation is of a new type that combines holography with the Wheeler-DeWitt formalism to produce a Wheeler-DeWitt theory that lives on the spatial boundary of a k=-1 FRW cosmology. We also argue for a more ambitious interpretation of the Wheeler-DeWitt CFT as a holographic dual of the entire Landscape.

description: We revisit the model of the laser with feedback and the minimal nonlinearity leading to chaos. Although the model has its origin in laser physics, with peculiarities related to the CO2 laser, it belongs to the class of the three dimensional paradigmatic nonlinear oscillator models giving chaos. The proposed model contains three key nonlinearities, two of which are of the type xy, where x and y are the fast and slow variables. The third one is of the type xz^2, where z is an intermediate feedback variable. We analytically demonstrate that it is essential for producing chaos via local or global homoclinic bifurcations. Its electronic implementation in the range of kilo Hertz region confirms its potential in describing phenomena evolving on different time scales.

description: Superfluidity or superconductivity with mismatched Fermi momenta appears in many systems such as charge neutral dense quark matter, asymmetric nuclear matter, and in imbalanced cold atomic gases. The mismatch plays the role of breaking the Cooper pairing, and the pair-breaking state cannot be properly described in the framework of standard BCS theory. I give a brief review on recent theoretical development in understanding unconventional color superconductivity, including gapless color superconductor, the chromomagnetic instabilities and the Higgs instability in the gapless phase. I also introduce a possible new framework for describing unconventional color superconductor.

Suturing the world : the micro-practices of care and the politics of life in Chiang Mai
Creators: name: Seo, Bo Kyeong
Publisher: name: The Australian National University
Year: 2015

description: Based on eighteen months of fieldwork between 2010 and 2012, this thesis examines how universal health coverage is shaped and experienced in Thailand. How might such an ambitious social project that aims to ensure every citizen access to a full-range of health services become feasible in a socially divided, politically unstable, lower-middle-income country like Thailand? This thesis investigates the establishment of universal health coverage not as a given condition but as a political and moral work in progress. How is the provision of care perceived, enacted, and assembled in the frontline of the Thai public health care system? What kinds of political subjectivities are implicated in the mundane and extraordinary struggles to make care accessible and durable? With special focus on the human stakes of health care for poor Thai and non-citizen Shan migrant populations, this thesis offers new ethnographic insights into the significance of micro-practices of care for the politics of life. Situated in a district hospital on the periphery of Chiang Mai City, I examine the multiple circuits of care threaded through everyday socio-cultural practice. Practices of care and their implications are multi-dimensional. Beginning with the workings of the public hospital, I show how caring and governing are interrelated. While the promise of the universal health coverage policy is mitigated by rules of eligibility and entitlement, hospital staff's aspirations to realize a government of care make this policy substantively universal. Ethnic minorities and Shan migrants in vulnerable situations actively utilize Thai public hospitals, navigating the perils of receiving the gift of care. I show how they elicit state care and secure a foothold in the political community through artful practices of being governed. In their struggles to maintain their family amidst structural violence and precariousness Shan women also employ tactics of creative subsistence that make life liveable. At junctures when the desire to care exceeds the boundaries of belonging and sameness, I explore how critically ill neonates and spiritual entities-alien others who hover at the margins of life-are drawn into alliances of care. I conceptualize the 'desire to care' as a conjunctural expression of the life-intensifying proclivities of medical, state, and spiritual sovereignty and argue that practices of care, even in micro forms, nourish potentials to create a sphere of relations and a politics of life. Highlighting people's intertwined experience of freedom and obligation, autonomy and dependence, I demonstrate how individual and collective pursuits of formulating relations of care dismantle and reassemble the notion of universal citizenship and entitlement. At its core, this thesis reorients care as a suturing and sutured state, practice that acts upon the world, and value accumulated by practice, which repairs, envisions, and transforms the human condition in a provisionary but concrete manner.

description: We review machine learning methods employing positive definite kernels. These methods formulate learning and estimation problems in a reproducing kernel Hilbert space (RKHS) of functions defined on the data domain, expanded in terms of a kernel. Working in linear spaces of function has the benefit of facilitating the construction and analysis of learning algorithms while at the same time allowing large classes of functions. The latter include nonlinear functions as well as functions defined on nonvectorial data. We cover a wide range of methods, ranging from binary classifiers to sophisticated methods for estimation with structured data.

description: Frequency noise greatly limits the resolution of high resolution fibre optic strain sensors. The experiments presented in this thesis provide an effective way of obtaining better strain resolution in systems limited by laser frequency noise. In this thesis two main methods are utilised; active frequency noise suppression through feedback control, and post processing noise removal. In chapters 2, 3, and 4, we explore different methods to reduce the frequency noise in lasers used to interrogate fibre interferometric strain sensing systems. We investigate the use of local fibre lasers and their applicability to high resolution strain sensing. We use radio frequency read out techniques to provide a high resolution read out of strain and frequency fluctuations. Then using active feedback, we lock the laser to a stable Mach-Zehnder interferometer. We demonstrate, with active feedback, ultra-high strain resolutions of 14 f{u220A}/{u221A}Hz at infrasonic frequencies. To allow for more flexibility and ease of use, we used a field programmable gate arrays for digital locking and signal processing systems. We present an analysis of the potential performance of a digital feedback system using the Pound-Drever-Hall technique. In this analysis, we discuss the noise sources and their affect on a digital feedback loop. We then experimentally characterise and verify the theoretical analysis. With this digital system we then explore the use of an absolute frequency reference. An interrogation system was designed and implemented that extends the range of an absolute sensing systems. Using this method, we are able to improve a free running system by up to 1.5 orders of magnitude whilst improving the range by a factor of 10 over standard pre-stabilised systems. We then propose and implement a frequency noise insensitive sensing system based on post processing techniques. We utilise time-delay interferometry, a technique developed for gravitational wave detection to eliminate frequency noise through post processing. The technique is combined with digitally-enhanced interferometry, and slightly modified to account for, and remove, several noise sources, including lead fibre phase noise, that is common to fibre optic strain sensors. The design and performance considerations are discussed and analysed, and a first time proof of concept experiment is reported. The design implemented has shown to significantly improve the performance of a frequency noise limited strain sensor.

description: This thesis is a compilation of applied epidemiological studies undertaken throughout the course of the Master of Philosophy in Applied Epidemiology (MAE) program. The focus of this thesis is on Aboriginal and Torres Strait Islander health and wellbeing and uses a strengths based, mixed methods approach. Community based participatory research methodologies were utilized in these studies. An outbreak investigation was also undertaken as part of the MAE competencies. This thesis includes the following studies: - The data analysis and major epidemiological studies explore the association between caring for country, through participation in a Ranger program, and wellbeing. A cross sectional analysis of data collected in Central Australia in 2017, comparing health and wellbeing (life satisfaction, general health, psychological wellbeing and family wellbeing) among Aboriginal and Torres Strait Islander people employed as Rangers (n=43) versus not employed as Rangers (n=160). - The Stronger Communities for Children (SCfC) program was evaluated through collection of cultural participation data (a key program outcome). Community based participatory research was utilised and community researchers were trained in delivering the survey through partnership with the Palngun Wurnangat Aboriginal Corporation, the Kardu Lurruth Ngala Purrungime Committee and the National Centre of Epidemiology and Population Health. - An outbreak investigation was undertaken of a cluster of Salmonella Typhimurium with a unique MLVA pattern in Canberra, ACT. Descriptive epidemiology and an environmental investigation was undertaken to identify the source of the pathogen, and implement public health measures to mitigate risk to the public of further infection. This thesis outlines additional activities undertaken during the MAE. Peer-reviewed articles, conference presentations, lesson plans and study proposals are included throughout.

Simulation study of earthquakes based on the two-dimensional Burridge-Knopoff model with the long-range interaction

description: Spatiotemporal correlations of the two-dimensional spring-block (Burridge-Knopoff) models of earthquakes with the long-range inter-block interactions are extensively studied by means of numerical computer simulations. The long-range interaction derived from an elasticd theory, which takes account of the effect of the elastic body adjacent to the fault plane, falls off with distance r as 1/r^3. Comparison is made with the properties of the corresponding short-range models studied earlier. Seismic spatiotemporal correlations of the long-range models generally tend to be weaker than those of the short-range models. The magnitude distribution exhibits a ``near-critical'' behavior, i.e., a power-law-like behavior close to the Gutenberg-Richter law, for a wide parameter range with its B-value, B\simeq 0.55, insensitive to the model parameters, in sharp contrast to that of the 2D short-range model and those of the 1D short-range and long-range models where such a ``near-critical'' behavior is realized only by fine-tuning the model parameters. In contrast to the short-range case, the mean stress-drop at a seismic event of the long-range model is nearly independent of its magnitude, consistently with the observation. Large events often accompany foreshocks together with a doughnut-like quiescence as their precursors, while they hardly accompany aftershocks with almost negligible seismic correlations observed after the mainshock.
The application of jazz methods to Brazilian drum kit improvisatory techniques in choro, samba and bossa nova

Subjects: subject: Drum Methods (Jazz)Brazil

description: There are a number of excellent books currently available that address Brazilian drum kit playing, but across all these books, there is a general lack of ideas for further development and advanced applications, particularly improvisation. Meanwhile, there are many excellent texts that deal with improvisation and the development of improvising skills, but they are largely within the realms of jazz drumming. As a drummer with a long interest in jazz and Brazilian styles, I came to a point where an in-depth look at the methodology for practicing improvisation within the framework of Brazilian music was a clear next step. It is something I felt the need for as a performer and as an educator. The first section of this thesis provides: a background to the characteristic sounds of choro, samba and bossa; background information on the development of Brazilian drum kit playing; a look at Brazilian phrasing concepts; and a discussion of rhythmic frameworks in these styles. The second section addresses practice and performance methodology based within the framework laid out by the earlier chapters. A significant part of this is the outlining of a graduated process for the development of three- and four{u00AD}way co-ordination. It also includes analysis of rhythmic tension-and-release devices and discussion of some of the subtler aspects of Brazilian drum kit performance. The final part addresses the development of solo ideas, primarily through motivic development. The ideas presented throughout are focused on the concepts of fluent and responsive drumming.

description: The General Data Protection Regulation (EU)2016/679 passed by the European Union prohibits any data collection and processing that was conducted without the consent of the individuals involved. Especially images showing faces are often subject to these regulations and therefore, either need to be removed or anonymized. Early approaches however were often troubled by strong visual artifacts. In this work, we propose a novel anonymization pipeline that generates a proxy face for a group of individuals by taking advantage of the semantics of the latent space of generative adversarial networks. Experiments have shown that by following a 𝑘-same approach and utilizing different clustering techniques, privacy for the individuals involved can be greatly enhanced, while preserving important facial characteristics.
Correlation between molecular orbitals and doping dependence of the electrical conductivity in electron-doped Metal-Phthalocyanine compounds

description: We have performed a comparative study of the electronic properties of six different electron-doped metal phthalocyanine (MPc) compounds (ZnPc, CuPc, NiPc, CoPc, FePc, and MnPc), in which the electron density is controlled by means of potassium intercalation. In spite of the complexity of these systems, we find that the nature of the underlying molecular orbitals produce observable effects in the doping dependence of the electrical conductivity of the materials. For all the MPc's in which the added electrons are expected to occupy orbitals centered on the ligands (ZnPc, CuPc, and NiPc), the doping dependence of the conductivity has an essentially identical shape. This shape is different from that observed in MPc materials in which electrons are also added to orbitals centered on the metal atom (CoPc, FePc, and MnPc). The observed relation between the macroscopic electronic properties of the MPc compounds and the properties of the molecular orbitals of the constituent molecules, clearly indicates the richness of the alkali-doped metal-phthalocyanines as a model class of compounds for the investigation of the electronic properties of molecular systems.

description: This work introduces advanced computational techniques for modeling the time evolution of compact binary systems using machine learning. The dynamics of compact binary systems, such as black holes and neutron stars, present significant nonlinear challenges due to the strong gravitational interactions and the requirement for precise numerical simulations. Traditional methods, like the post-Newtonian approximation, often require significant computational resources and face challenges in accuracy and efficiency. Here, we employed machine learning algorithms, including deep learning models like Long Short-Term Memory (LSTM) and Temporal Convolutional Network (TCN), to predict the future evolution of these systems based on extensive simulation data. Our results demonstrate that employing both LSTM and TCN even as black-box predictors for sequence prediction can also significantly improve the prediction accuracy without PINNs as PDE solvers with prior knowledge or inductive bias. By employing LSTM and TCN, we obtained $R^2$ values of 99.74\% and 99.19\% for the evolutionary orbits of compact binaries dataset, respectively. Our models demonstrate the ability to effectively capture the dynamics of the binaries, achieving high prediction performance with significantly reduced computational overhead by a factor of 40, compared to conventional numerical methods. This study paves the way for more effective and computationally scalable approaches to the understanding of gravitational phenomena and predictive modeling in gravitational-wave astronomy.

description: We improve strong lensing constraints on cosmological parameters in light of the new measurement of the velocity dispersion function of early-type galaxies based on the SDSS DR5 data and recent semi-analytical modeling of galaxy formation. Using both the number statistics of the CLASS statistical sample and the image separation distribution of the CLASS and the PANELS radio-selected lenses, we find the cosmological matter density $\Om = 0.25^{+0.12}_{-0.08}$ (68% CL) assuming evolutions of galaxies predicted by a semi-analytical model of galaxy formation and $\Om = 0.26^{+0.12}_{-0.08}$ assuming no evolution of galaxies for a flat cosmology with an Einstein cosmological constant. For a flat cosmology with a generalized dark energy, we find the non-evolving dark energy equation of state $w_x < -1.2$ ($w_x < -0.5$) at the 68% CL (95% CL).

Thermodynamic Behavior of Time-Dependent Wormholes in Palatini $f(R)$ Gravity

description: In the frame work of Palatini approach to modified $f(R)$ theories of gravity, we attempt to investigate the thermodynamic behavior of time-dependent wormhole geometries. By considering an evolving wormhole spacetime, we find the field equations in Palatini $f(R)$ gravity. The energy density and pressure are redefined in order to satisfy the continuity equation. To discuss the thermodynamic behavior, an expression for the variation of total entropy is obtained. Then, we extend our discussions to apparent and event horizons of evolving wormholes. We employ the radius of apparent and event horizons to determine the validity of generalized second law (GSL) of thermodynamics which states that the variation of total entropy is non-negative.
Guarding the periphery : the Australian army in Papua New Guinea, 1951 - 1975

description: For twenty-four years Papua New Guinean units were a substantial part of the Australian Army, constituting the only regular force in Papua New Guinea (PNG) during the 1950s, and providing two battalions to secure the border with Indonesia during Confrontation. By 1972, shortly before Papua New Guinean independence, Papua New Guineans made up almost one in ten of the regular soldiers in the Australian Army. Just three years later, these men became the defence force of an independent PNG. Yet, there has been little scholarship that has addressed in detail the development of this force, the experiences of the soldiers within it, and its interaction with both the Australian colonial administration and PNG's independence in 1975. This thesis is the first study of the Australian Army in PNG to make extensive use of archival material and oral histories from both Australia and PNG. In doing so, it seeks to take advantage of under-utilised Papua New Guinean sources as well as the wealth of material that has only recently been released. This thesis explores the development of Papua New Guinean units from a colonial force to the independent Papua New Guinean Defence Force. It finds that while the Papua New Guinean units were initially raised overwhelmingly in the interests of Australian defence, the needs of an independent PNG were increasingly taken into account by the Army to such an extent that they coexisted as a secondary consideration for a significant period, becoming the Army's primary concern during the decade before independence. This thesis also examines the centrality of the treatment of Papua New Guineans to the development of the Army in PNG, showing that the changing perception of this unique group of soldiers shaped their role within the force. Finally, it questions the assumption that the Australian Army remained separate from wider developmental changes occurring in PNG during this period, revealing that the Army prepared for the possibility of Papua New Guinean nationhood even as it was tasked with defending Australia's interests. By examining the history of the Australian Army in PNG, and those who served within it, this thesis broadens our conception of how Australia was defended and of who defended it.

description: We report the detection of extended X-ray emission from two high-redshift radio quasars. These quasars, J1405+0415 at $z$=3.208 and J1610+1811 at $z$=3.118, were observed in a Chandra snapshot survey selected from a complete sample of the radio-brightest quasars in the overlap area of the VLA-FIRST radio survey and the Sloan Digital Sky Survey. The extended X-ray emission is located along the line connecting the core to a radio knot or hotspot, favoring the interpretation of X-ray jets. The inferred rest frame jet X-ray luminosities from 2--30 keV would be of order 10$^{45}$ erg~s$^{-1}$ if emitted isotropically and without relativistic beaming. In the scenario of inverse Compton scattering of the cosmic microwave background (CMB), X-ray jets without a coincident radio counterpart may be common, and should be readily detectable to redshifts even beyond 3.2 due to the (1+$z$)$^4$ increase of the CMB energy density compensating for the (1+$z$)$^{-4}$ cosmological diminution of surface brightness. If these can be X-ray confirmed, they would be the second and third examples of quasar X-ray jets without detection of underlying continuous radio jets.

description: Con la continua diffusione di strumenti software semplici e potenti per editare le immagini, la contraffazione di immagini è diventata sempre più comune; contemporaneamente si è diffuso l'interesse per l'image forensic cioè quelle metodologie e algoritmi capaci di rilevare l'integrità dell'immagine.
In letteratura sono stati proposti numerosi approcci per rilevare se un'immagine è stata contraffatta o per localizzare la contraffazione all'interno dell'immagine. Questi approcci principalmente si basano sul rilevamento della presenza, assenza o incongruenza di alcune tracce presenti tipicamente nelle immagini digitali.In particolare nella tesi verranno approfondite tre categorie di approcci:
1.	gli approcci basati sul Photo Response Non-Uniformity noise(considerato l'impronta digitale delle macchine fotografiche),
2.	gli approcci utilizzati per rilevare duplicazioni all'interno dell'immagine,
3.	gli approcci basati su descrittori sintetici dell'immagine.

description: Die Kompensation thermischer Einflüsse und daraus resultierender geometrischer Verlagerungen spielt eine bedeutende Rolle bei der Gewährleistung einer hohen Bearbeitungsqualität von Werkstücken in Zerspanungsprozessen. Übliche Vorgehensweisen zur Reduktion thermischer Verlagerungen während der Produktion gehen mit einem erheblichen Energiebedarf einher oder modellieren die komplexen Zusammenhänge thermischer Einflüsse nur ungenügend. Methoden des Maschinellen Lernens stellen einen vielversprechenden Ansatz zur Modellierung dar. Es wird eine Lösung angestrebt, die aufwandsarm auf Produktionsmaschinen ähnlicher Bauart übertragen werden kann. Derzeit ist ungeklärt, ob eine explizite oder implizite Modellierung der zeitlich multivarianten Daten eine ufriedenstellende Lösung bietet. Als besonders herausfordernd stellt sich die Verfügbarkeit von ausreichend vielen Datenbeispielen zur Modellierung der relevanten Größen dar.

description: We investigate the current-excited magnetization dynamics in a narrow ferromagnetic Permalloy wire by means of Lorentz microscopy, together with the results of simultaneous transport measurements. A detailed structural evolution of the magnetization is presented as a function of the applied current density. Local structural deformation, bidirectional displacement, and magnetization reversal are found below the Curie temperature with increasing the current density. We discuss probable mechanisms of observed features of the current-excited magnetization dynamics.
