Numerical study of three-body recombination for systems with many bound states
Creators: name: Wang, Jia

Publisher: name: arXiv
Year: 2011
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Three-body recombination processes are treated numerically for a system of three identical bosons. The two-body model potentials utilized support many bound states, a major leap in complexity that produces an intricate structure of sharp nonadiabatic avoided crossings in the three-body hyperradial adiabatic potentials at short distances. This model thus displays the usual difficulties of more realistic systems. To overcome the numerical challenges associated with sharp avoided crossings, the slow variable discretization (SVD) approach is adopted in the region of small hyperradii. At larger hyperradii, where the adiabatic potentials and couplings are smooth, the traditional adiabatic method suffices. Despite the high degree of complexity, recombination into deeply bound states behaves regularly due to the dominance of one decay pathway, resulting from the strong coupling between different recombination channels. Moreover, the usual Wigner threshold law must be modified for excited incident recombination channels.

description: Efficient numerical methods are still lacking to probe the unconventional dynamics of quantum many-body systems under non-unitary evolution. In this work, we use Faber polynomials to numerically simulate both the dynamics of non-Hermitian systems and the quantum jumps unravelling of the Lindblad dynamics. We apply the method to the non-interacting and interacting Hatano-Nelson models evolving from two different setups: i) a Néel state, and ii) a domain wall. In the first case, we study how interactions preserve the initial magnetic order against the skin effect. In the second example, we present numerical evidence of the existence of an effective hydrodynamic description for the domain-wall melting problem in the non-interacting limit. Additionally, we investigate both the conditional and unconditional dynamics of the quantum jump unravelling in two quantum spin chains, which exhibit either the non-Hermitian or the Liouvillian skin effect. This numerical method inherently generalises the well-established method based on Chebyshev polynomials to accommodate non-Hermitian scenarios.

description: In a superconducting ferromagnet, the superconducting state appears in the ferromagnetic phase where usually a domain structure has already developed. We study the influence of the superconducting screening currents on a stripe structure with out-of-plane magnetization, in a film of arbitrary thickness. We find that superconductivity always induces a shrinkage of the domains, and there is a critical value of penetration depth below which a mono-domain structure is more stable than the periodic one. Furthermore we investigate the possible different effects of singlet and triplet superconductivity on the domain width, as well as the conditions for the existence of vortices in the domains. The obtained results are then discussed in light of the experimental data of superconducting ferromagnets URhGe, UGe2, and UCoGe.

Wetland identification, calssification and evaluation for Fish Creek provincial park
Creators: name: Mosig Reidl, Paola
Publisher: name: Environmental Design
Year: 2002

description: Bibliography: p. 202-214
description: This Master's Degree Project (MDP) resulted in an inventory of the wetlands of Fish Creek Provincial Park (FCPP). The wetlands were ciqsslfieql using the Canadian Wetland Classification System, and their general characteristics were investigated in order to develop recommendations that will assist the pork toff wlth wetland management. Concerning wetland classes, all the wetlands in the Park but one were classified as Marshes, while the remaining was classified as Shallow Water. Six welland forms/subforms were present inFCPP; Riparian Meltwater Channel Marhes (RMCM5), Riparian Stream Marhses (RSM). Spring Marshes (SMs),. Riporl.qn Floodiploin Morshs (RFMs),, Isolated q*i Marshes (lBMs), dnd Riparian Stream Waters (RSWs). The RMCMs.were the most common and the RSWs the least, According to their type, 0% of these wetlands were classified as Graminold (Sedge). Carexsp. was the most common of all wetland plants. For the classification of wetlands in the Pork,. It Is suggested that consideration be given to Stewart and Kantrud's (1971) classification system because it is based upon wetland's hycirplogloal regime, which is responsible for their distinctive vegetation composition and general characteristics (seasonally flooded wetlands predominated in the Park). Approximately 90% of the wetlands In FCPP are fed by groundwater dischaig (l..e, they are terrlgenous). Others get their water directly from the creek or the river (Le',l itogenous) and from stormwater outfcills. The Park's wetlands that receive stormwater Inputs from the, city still contain a great variety of plant-species and, therefore, they not only provide us with services, but they also provide several wildlife species with habitat. However, if there were future needs to locate more stormwater outfalls in the Park, It would be preferable to construct artificial wetlands for thl§ purpose (it has already started being done) than to direct the stormwater to the naturally existing wetlands. In general, Fish ,Creek's wetlands support a variety of ecological functions related fo hydrology, native vegetation, and wildlife habitat. Considering That They are surrounded by urbanization, it is the author's opinion that they are in fairly good condition. A total of 40 wetlands (including wetland complexes and constructed wetlands). was, found In the Park, and the number of these is probably higher considering the areas that could not be accessed. ma way, all of Fish Creek's wetlands are linked to one another, forming a whole wetland complex. No single wetland plays an essential role in providing habitat for wildlife and goods and services for us; it is the sum of all the different types of wetlands in the Park that does, It is recommended that for their management and other considerations, FCPP's wetlands be thought-of as being one sole complex system. A' number of specific actions for wetland management In the Park are recommended.

description: The local chiral symmetry between clockwise (CW) and counter-clockwise (CCW) propagating light in a deformed microcavity can be broken by wave optics effects, which become significant as the cavity size approaches the wavelength. We show that the spatial separation of the CW and CCW ray orbits underlying the high quality factor resonant modes results in unidirectional emission in free space. In the presence of a waveguide, evanescent coupling also becomes directional, and the output direction can be varied by selecting the coupling position along the cavity boundary. Our results demonstrate that the local chirality can be utilized to control the output directionality and enhance the collection efficiency of emission from ultrasmall resonators.

On the Origin of the Slow Speed Solar Wind: Helium Abundance Variations

Publisher: name: arXiv
Year: 2012
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: The First Ionization Potential (FIP) effect is the by now well known enhancement in abundance over photospheric values of Fe and other elements with first ionization potential below about 10 eV observed in the solar corona and slow speed solar wind. In our model, this fractionation is achieved by means of the ponderomotive force, arising as Alfvén waves propagate through or reflect from steep density gradients in the solar chromosphere. This is also the region where low FIP elements are ionized, and high FIP elements are largely neutral leading to the fractionation as ions interact with the waves but neutrals do not. Helium, the element with the highest FIP and consequently the last to remain neutral as one moves upwards can be depleted in such models. Here, we investigate this depletion for varying loop lengths and magnetic field strengths. Variations in this depletion arise as the concentration of the ponderomotive force at the top of the chromosphere varies in response to Alfvén wave frequency with respect to the resonant frequency of the overlying coronal loop, the magnetic field, and possibly also the loop length. We find that stronger depletions of He are obtained for weaker magnetic field, at frequencies close to or just above the loop resonance. These results may have relevance to observed variations of the slow wind solar He abundance with wind speed, with slower slow speed solar wind having a stronger depletion of He.

description: Polarized and unpolarized neutron scattering experiments on the frustrated ferromagnetic spin-1/2 chain LiCuVO4 show that the phase transition at HQ of 8 Tesla is driven by quadrupolar fluctuations and that dipolar correlations are short-range with moments parallel to the applied magnetic field in the high-field phase. Heat-capacity measurements evidence a phase transition into this high-field phase, with an anomaly clearly different from that at low magnetic fields. Our experimental data are consistent with a picture where the ground state above HQ has a next-nearest neighbour bond-nematic order along the chains with a fluid-like coherence between weakly coupled chains.

description: We theoretically study the vortex formation from the collision of the domain walls in phase-separated two-component Bose-Einstein condensates. The collision process mimics the tachyon condensation for the annihilation of D-brane and anti-D-brane in string theory. A pair annihilation leaves the quantized vortices with superflow along their core, namely `superflowing cosmic strings'. It is revealed that the line density and the core size of the vortices depend on the initial distance between the walls.

Bryant can only be shrinking or steady. We also show that the space of symmetries (vector fields that annihilate via the Lie derivative) of a torsion-free $G_2$-structure on a compact 7-manifold is canonically isomorphic to $H^1(M,\mathbb{R})$. Some comparisons with Ricci solitons are also discussed, along with some future directions of exploration.
Multilinguality and the use of vocabularies at Europeana

description: Europeana gathers millions of metadata records from over 3500 libraries, archives and museums across Europe. Such a diversity with many quality issues (sparseness, heterogeneity, multilinguality). We present how Europeana and its partners work to address these issues, in a collaborative and flexible fashion. The Europeana Data Model paves the way for gathering richer metadata, but all parties need to exploit this potential. Especially, populating the data model's elements with multilingual linked open data vocabularies can bring a lot of value. We encourage our partners to publish richer metadata that exploits the controlled vocabularies they often already use. We also perform automatic metadata enrichment, using a purpose-built linked-data based "entity collection" as target. Finally, partners have also embarked on producing their own automatic metadata enrichments. In parallel, the Europeana network has developed a tier system for the Europeana Publishing Framework, which enables measuring and reporting on important aspects of metadata quality in the Europeana datasets.

description: The implementation of an incentive zoning policy, known as the Bonus System, has influenced the development of Calgary' s downtown for over 20 years. This planning tool encourages the development of a unique type of public amenity space referred to as privately owned public space. An inventory of several privately owned public spaces was conducted and the spaces were critically analysed in terms of urban design principles which were synthesized from several sources. This MDP reviews the goals and objectives of the Bonus System policy and evaluates the success of the policy in light of the urban design principles. The results of the study indicate that the City has not achieved a balance between quality public amenity space and increased density granted to developers. The analysis suggests that many existing spaces provide little benefit to the public. Revisions to the policy are recommended in order to reflect the evolving vision of the downtown and the changing needs of the users of public space. Further study is necessary to determine the types of public amenities that will be required in the downtown in the future. A requirement to provide a high quality of urban design could improve the benefits this unique form of public space provides. The bonus policy should therefore be supported through the adoption of urban design guidelines and a design review process. The analysis indicates that incentive zoning policy in Calgary has not succeeded in establishing a comprehensive public space network. It is imperative that the City take the lead in developing key civic spaces that will form the structure of a healthy public realm.

The workshop was held in Reykjavik, Iceland, on June 9, 2011, as part of DisCoTec 2011. The aim of the WWV workshop series is to provide an interdisciplinary forum to facilitate the cross-fertilization and the advancement of hybrid methods that exploit concepts and tools drawn from Rule-based programming, Software engineering, Formal methods and Web-oriented research. Nowadays, indeed, many companies and institutions have diverted their Web sites into interactive, completely-automated, Web-based applications for, e.g., e-business, e-learning, e-government, and e-health. The increased complexity and the explosive growth of Web systems have made their design and implementation a challenging task. Systematic, formal approaches to their specification and verification can permit to address the problems of this specific domain by means of automated and effective techniques and tools. In response to this year's call for papers, we received 9 paper submissions. The Program Committee of WWV 2011 collected three reviews for each paper and held an electronic discussion leading to the selection of 7 papers for presentation at the workshop. In addition to the selected papers, the scientific programme included an invited lecture by Elie Najm.

Vocabularies and quality improvement of library catalogues
Creators: name: Király, Péter
Publisher: name: Zenodo
Year: 2023
Subjects: Controlled vocabularies
Semantic web
Information architecture

description: QA catalogue is a metadata quality assessment tool developed for MARC21 and PICA metadata schema based library catalogues. Catalogues use vocabularies internally for recording their own structure and the terms particular data elements might contain, and externally for enhancing the descriptive data elements. This latter category covers two main areas: subject indexing and normalisation of (personal, family, corporate, geographical) names, titles and events. The tool reads MARC or PICA files (in different formats), analyses some quality dimensions, and saves the results into CSV files.

description: The service conditions of wheelset bearings has a direct impact on the safe operation of railway heavy haul freight trains as the key components. However, speed fluctuation of the trains and few fault samples are the two main problems that restrict the accuracy of bearing fault diagnosis. Therefore, a cross-machine transfer diagnosis (pyDSN) network coupled with interpretable modulated differentiable short-time Fourier transform (STFT) and physics-informed balanced spectrum quality metric is proposed to learn domain-invariant and discriminative features under time-varying speeds. Firstly, due to insufficiency in extracting extract frequency components of time-varying speed signals using fixed windows, a modulated differentiable STFT (MDSTFT) that is interpretable with STFT-informed theoretical support, is proposed to extract the robust time-frequency spectrum (TFS). During training process, multiple windows with different lengths dynamically change. Also, in addition to the classification metric and domain discrepancy metric, we creatively introduce a third kind of metric, referred to as the physics-informed metric, to enhance transferable TFS. A physics-informed balanced spectrum quality (BSQ) regularization loss is devised to guide an optimization direction for MDSTFT and model. With it, not only can model acquire high-quality TFS, but also a physics-restricted domain adaptation network can be also acquired, making it learn real-world physics knowledge, ultimately diminish the domain discrepancy across different datasets. The experiment is conducted in the scenario of migrating from the laboratory datasets to the freight train dataset, indicating that the hybrid-driven pyDSN outperforms existing methods and has practical value.

description: Bipolar outflows constitute some of the best laboratories to study shock chemistry in the interstellar medium. A number of molecular species have their abundance enhanced by several orders of magnitude in the outflow gas, likely as a combined result of dust mantle disruption and high temperature gas chemistry, and therefore become sensitive indicators of the physical changes taking place in the shock. Identifying these species and understanding their chemical behavior is therefore of high interest both to chemical studies and to our understanding of the star-formation process. Here we review some of the recent progress in the study of the molecular composition of bipolar outflows, with emphasis in the tracers most relevant for shock chemistry. As we discuss, there has been rapid progress both in characterizing the molecular composition of certain outflows as well as in modeling the chemical processes likely involved. However, a number of limitations still affect our understanding of outflow chemistry. These include a very limited statistical approach in the observations and a dependence of the models on plane-parallel shocks, which cannot reproduce the observed wing morphology of the lines. We finish our contribution by discussing the chemistry of the so-called extremely high velocity component, which seems different from the rest of the outflow and may originate in the wind from the very vicinity of the protostar.
