Quasi-local holography and quasi-local mass of classical fields in Minkowski spacetime

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: The 2-surface characterization of special classical radiative Higgs-, Yang-Mills and linear zero-rest-mass (l.z.r.m) fields with any spin is investigated. We determine all the zero quasi-local mass Higgs- and Yang-Mills field configurations with compact semisimple gauge groups, and show that they are plane waves (provided the Higgs field is massless and linear) and appropriate generalizations of plane waves (`Yang-Mills pp-waves'), respectively. A tensor field (generalizing the energy-momentum tensor for the Maxwell field and of the Bel-Robinson tensor for the linearized gravitational field) is found by means of which the pp-wave nature of the solutions of the l.z.r.m. field equations with any spin can be characterized equivalently. It is shown that these radiative Yang-Mills and l.z.r.m. fields, given on a finite globally hyperbolic domain D, are determined completely by certain unconstrained data set on a closed spacelike 2-surface, the `edge of D'. These pure radiative solutions are shown to determine a dense subset in the set of solutions of various (Yang-Mills and l.z.r.m.) field equations. Thus for these field configurations some `classical quasi-local holography' holds.

Presence, clarity and the space of receptivity in counselling : shambhala buddhist counsellors’ narratives of experience
Creators: name: Rodrigues, Jennifer
Publisher: name: University of British Columbia
Year: 2009

description: This study is an inquiry into the experiences of Shambhala Buddhist counsellors. My interest lies in whether the Shambhala Buddhism paradigm of health and basic goodness and the practice of working with emotions affect counsellors in their relationship with clients, have relevance for counselling practice, and pragmatic usefulness for counsellor training. My question is: does the practice and study of Shambhala Buddhism inform their counselling and how is this distilled in action and in interaction? The participants are Shambhala Buddhist counsellors who have a history and depth of experience in both Buddhism and counselling. My research path comprised interviews, a group dialogue and an art-making component. Congruent with counselling and Buddhist approaches, I inquired into these counsellors' stories of experience and practiced mindfulness and openness as my researcher's stance. I did multiple readings of the various texts, investigating the participants' view, presence, and interaction with clients. To analyze and present the findings, I used the Buddhist logic of ground, path, and fruition. My inquiry outlines how these counsellors' view of basic goodness and selfconstruct is embodied in practice. Enhanced counsellor awareness, profound empathic connection, attentiveness to self and other and in relationship, and openness without agenda give rise to the conceptual clarity that informs skillful action. It results in an openhearted presence, clarity, and receptivity. Strategically helping clients examine their experience and how their mind constructs that experience shifts clients' relationship to pain, themselves, and others. This enhances clients' self-reflectivity, self-acceptance, and disengagement from fixed patterns and constructed storylines that maintain suffering. This focus helps clients develop greater emotional configurations and more fluid ways of being. These insights and practices address core, fundamental, and valuable components of counselling. They have great relevance for the relational process and experiential reality of counselling. This research enlarges the conversation on empathy and counsellor competency. It points to the educational significance of incorporating experiential expressive forms and practices of embodied learning to enhance counsellor self and other awareness and the possibility for attunement. This study offers substantive theoretical and practical implications for counselling practice and for the education of counsellors.

description: The presence of degeneracies can considerably worsen the measure of the neutrino oscillation parameters $θ_{13}$ and $δ$. We study the physics reach of a specific ``CERN'' setup, using a standard $β$-Beam and Super-Beam facility. These facilities have a similar sensitivity in both parameters. Their combination does not provide any dramatic improvement as expected due to their almost identical L/E ratio. We analyse if adding the correspondent disappearance channels can help in reducing the effect of degeneracies in the $(θ_{13},δ)$ measure.

description: We calculate in the SU(6) gauge theory the mass of the lightest flux loop that winds around a spatial torus, as a function of the torus size, taking care to achieve control of the main systematic errors. For comparison we perform a similar calculation in SU(4). We demonstrate approximate linear confinement and show that the leading correction is consistent with what one expects if the flux tube behaves like a simple bosonic string at long distances. We obtain similar but less accurate results for stable (k-)strings in higher representations. We find some evidence that for k>1 the length scale at which the bosonic string correction becomes dominant increases as N increases. We perform all these calculations not just for long strings, up to about 2.5`fm' in length, but also for shorter strings, down to the minimum length, lc = 1/Tc, where Tc is the deconfining temperature. We find that the mass of the ground-state string, at all length scales, is not very far from the simple Nambu-Goto string theory prediction, and that the fit improves as N increases from N=4 to N=6. We estimate the mass of the first excited string and find that it also follows the Nambu-Goto prediction, albeit more qualitatively. We comment upon the significance of these results for the string description of SU(N) gauge theories in the limit of infinite N.

description: Epitaxial quantum dots have emerged as one of the best single-photon sources, not only for applications in photonic quantum technologies but also for testing fundamental properties of quantum optics. One intriguing observation in this area is the scattering of photons with subnatural linewidth from a two-level system under resonant continuous wave excitation. In particular, an open question is whether these subnatural linewidth photons exhibit simultaneously antibunching as an evidence of single-photon emission. Here, we demonstrate that this simultaneous observation of subnatural linewidth and antibunching is not possible with simple resonant excitation. First, we independently confirm single-photon character and subnatural linewidth by demonstrating antibunching in a Hanbury Brown and Twiss type setup and using high-resolution spectroscopy, respectively. However, when filtering the coherently scattered photons with filter bandwidths on the order of the homogeneous linewidth of the excited state of the two-level system, the antibunching dip vanishes in the correlation measurement. Our experimental work is consistent with recent theoretical findings, that explain antibunching from photon-interferences between the coherent scattering and a weak incoherent signal in a skewed squeezed state.

Beyond Time VI: A Unified Framework for the Emergence of Temporal Experience from Relativistic and Thermodynamic Constraints
Creators: name: Yildirim, Kubilay
Publisher: name: Zenodo
Year: 2025

description: Abstract:This paper proposes a novel hypothesis that time is not a fundamental dimension of the universe but an emergent scalar property arising from the boundary constraints imposed by the speed of light (c) and absolute zero (0 K). By redefining time as the rate of distinguishable state transitions within physical systems, this framework offers a conceptual unification of relativity and thermodynamics. Through this lens, spacetime geometry, entropy, and causality are emergent phenomena shaped by energy flow and information resolution, rather than inherent dimensions. This hypothesis reframes time as a consequence of state-change dynamics and suggests a new pathway for integrating general relativity, quantum mechanics, and thermodynamics into a coherent, unified model.

description: The detailed analysis of nonperturbative contributions to the electromagnetic quark form factor is performed within the framework of the instanton liquid model (ILM) of the QCD vacuum. The method of the path-ordered Wilson exponentials is applied to evaluate explicitly the instanton corrections. By using the Gaussian interpolation of the constrained instanton solution, it is shown that the instantons yield the logarithmic corrections to the amplitudes in high energy limit which are exponentiated in small instanton density parameter.

description: It has recently been discovered that many biological systems, when represented as graphs, exhibit a scale-free topology. One such system is the set of structural relationships among protein domains. The scale-free nature of this and other systems has previously been explained using network growth models that, while motivated by biological processes, do not explicitly consider the underlying physics or biology. In the present work we explore a sequence-based model for the evolution protein structures and demonstrate that this model is able to recapitulate the scale-free nature observed in graphs of real protein structures. We find that this model also reproduces other statistical feature of the protein domain graph. This represents, to our knowledge, the first such microscopic, physics-based evolutionary model for a scale-free network of biological importance and as such has strong implications for our understanding of the evolution of protein structures and of other biological networks.

description: Td-WTe2 is a topological Weyl semimetal. WTe2 in the orthorhombic structure is stable at room temperature. Elastic, electronic, bonding, and optoelectronic properties of WTe2 have been investigated in detail in this work using the density functional theory. Elastic behaviour together with anisotropy indices of WTe2 have been investigated for the first time. Bonding nature among the constituent atoms and electric field polarization dependent optical constants have also been explored for the first time. WTe2 is elastically anisotropic; optical anisotropy on the other hand is low. The electronic band structure reveals quasi-linear dispersions along certain direction in the Brillouin zone with semi-metallic features. The Fermi level is located at a pseudogap separating bonding and anti-bonding density of states. The electronic effective mass tensor is predicted to be highly direction dependent. The energy dispersion is significantly weaker in the c-direction. The bonding in WTe2 is an admixture of covalent and metallic bonds. Optoelectronic properties show strongly reflecting character over a wide band of photon energies. The compound is a strong absorber of ultraviolet radiation. The Debye temperature has been calculated from the elastic constants. We have compared all the calculated physical properties of WTe2 with those of isostructural MoTe2 Weyl semimetals. The properties of WTe2 and MoTe2 have been compared and contrasted. The calculated parameters of WTe2 have also been compared with those already available in the literature. Very good agreements have been found.

description: The 2D layered Ruddlesden-Popper crystal structure can host a broad range of functionally important behaviors. Here we establish extraordinary configurational disorder in a two dimensional layered Ruddlesden-Popper (RP) structure using entropy stabilization assisted synthesis. A protype A2CuO4 RP cuprate oxide with five components (La, Pr, Nd, Sm, Eu) on the A-site sublattice is designed and fabricated into epitaxial single crystal films using pulsed laser deposition. By comparing (La0.2Pr0.2Nd0.2Sm0.2Eu0.2)2CuO4 crystals grown under identical conditions but different substrates, it is found that heteroepitaxial strain plays an important role in crystal phase formation. When grown on a near lattice matched substrate, the high entropy oxide film features a T'-type RP structure with uniform A-site cation mixing and square-planar CuO4 units, however, growing under strong compressive strain results in a single crystal non-RP cubic phase consistent with a CuX2O4 spinel structure. These observations are made with a range of combined characterizations using X-ray diffraction, atomic-resolution scanning transmission electron microscopy, energy-dispersive X-ray spectroscopy, and X-ray absorption spectroscopy measurements. Designing configurational complexity and moving between 2D layered RP and 3D cubic crystal structures in this class of cuprate materials opens many opportunities for new design strategies related to magnetoresistance, unconventional superconductivity, ferroelectricity, catalysis, and ion transport.
Entry strategies and performance of new ventures in clusters and isolation

Publisher: name: University of British Columbia
Year: 2009

description: This thesis includes three distinct manuscripts which help to elucidate the impacts of location externalities on entry strategies and performance of heterogeneous new ventures, as well as on the overall regional entrepreneurial activity. The first manuscript studies location choices of de novo entrants as a function of their initial resources and capabilities. It reveals that weak and strong entrants have distinct preferences for various location attributes reflecting both the differences in externalities they face and the value of such externalities in facilitating entry, maturation, and future prospects of profitability. The second manuscript reveals that geographical industry clustering matters to survival of new entrants. Moreover, firm specific factors and strategies which enhance survival vary significantly between different levels of industrial clustering. It shows that the initial endowments of resources and capabilities provide longer adolescence period for firms in clusters. The third manuscript argues that the causal links between entry and failure rates also flow from failure to entry. It shows that exit of local older firms stimulate entry and renewal. For the empirical analyses I used a longitudinal data set developed by Statistics Canada, which provides detailed firm level data for all firms operating in Canada from 1984 to 1998 as well as their employment, financial characteristics, industry affiliation, and location.

description: Detailed 2D turbulence measurements from the DIII-D tokamak provide an explanation for how resonant magnetic perturbations (RMPs) raise the L-H power threshold $P_\textrm{LH}$ [P. Gohil et al., Nucl. Fusion 51, 103020 (2011)] in ITER-relevant, low rotation, ITER-similar-shape plasmas with favorable ion $\nabla B$ direction. RMPs simultaneously raise the turbulence decorrelation rate $Δω_D$ and reduce the flow shear rate $ω_\textrm{shear}$ in the stationary L-mode state preceding the L-H transition, thereby disrupting the turbulence shear suppression mechanism. RMPs also reduce the Reynolds stress drive for poloidal flow, contributing to the reduction of $ω_\textrm{shear}$ On the ~100 μs timescale of the L-H transition, RMPs reduce Reynolds-stress-driven energy transfer from turbulence to flows by an order of magnitude, challenging the energy depletion theory for the L-H trigger mechanism. In contrast, non-resonant magnetic perturbations, which do not significantly affect $P_\textrm{LH}$, do not affect $Δω_D$ and only slightly reduce $ω_\textrm{shear}$ and Reynolds-stress-driven energy transfer.

Creators: name: Diehl, Martin
name: Niehuesbernd, Jörn
name: Bruder, Enrico
Publisher: name: MDPI
Year: 2024

description: The influence of grain shape and crystallographic orientation on the global and local elastic and plastic behaviour of strongly textured materials is investigated with the help of full-field simulations based on texture data from electron backscatter diffraction (EBSD) measurements. To this end, eight different microstructures are generated from experimental data of a high-strength low-alloy (HSLA) steel processed by linear flow splitting. It is shown that the most significant factor on the global elastic stress–strain response (i.e., Young’s modulus) is the crystallographic texture. Therefore, simple texture-based models and an analytic expression based on the geometric mean to determine the orientation dependent Young’s modulus are able to give accurate predictions. In contrast, with regards to the plastic anisotropy (i.e., yield stress), simple analytic approaches based on the calculation of the Taylor factor, yield different results than full-field microstructure simulations. Moreover, in the case of full-field models, the selected microstructure representation influences the outcome of the simulations. In addition, the full-field simulations, allow to investigate the micro-mechanical fields, which are not readily available from the analytic expressions. As the stress–strain partitioning visible from these fields is the underlying reason for the observed macroscopic behaviour, studying them makes it possible to evaluate the microstructure representations with respect to their capabilities of reproducing experimental results.

An evaluation of medication adherence in children with attention-deficit/hyperactivity disorder using the theory of reasoned action and planned behaviour
Creators: name: Scoular, Douglas
Publisher: name: University of British Columbia
Year: 2009

description: Medication to treat children with Attention-Deficit/Hyperactivity Disorder (ADHD) has been shown to be highly efficacious. Despite that, medication adherence rates have been shown to range from 60 to 80%. Mothers have an important role in providing medication to their children with ADHD. In predicting mothers' medication providing behaviour, mothers' cognitions may be an important factor. A theoretical model, The Theory of Reasoned Action and Planned Behaviour (TRAPB), was used to evaluate mothers' cognitions in predicting mothers' medication adherence behaviour for their children with ADHD. This theory proposes that an individual's attitude, subjective norm, and perceived behaviour control cognitions predict their intentions to perform behaviour, and that intentions predict actual behaviour. Fifty-five mothers and their elementary school age children with ADHD took part in the study. Mothers provided their attitudes, subjective norms, perceived behavioral control and intentions regarding providing medication to their children over an upcoming 2-week period. Both mothers and children reported medication adherence information during the 2-week period. Although mothers' attitudes and subjective norms predicted their intentions to provide medication, mothers' intentions failed to predict their medication adherence behaviour. Thus, this study's results suggest limited clinical applications for the TRAPB theory with regards to predicting medication adherence in children with ADHD. Some evidence, however, was presented that individual TRAPB items, along with non-TRAPB variables were predictive of mothers' medication adherence.

description: We consider how well the dark energy equation of state $w$ as a function of red shift $z$ will be measured using current and anticipated experiments. We use a procedure which takes fair account of the uncertainties in the functional dependence of $w$ on $z$, as well as the parameter degeneracies, and avoids the use of strong prior constraints. We apply the procedure to current data from WMAP, SDSS, and the supernova searches, and obtain results that are consistent with other analyses using different combinations of data sets. The effects of systematic experimental errors and variations in the analysis technique are discussed. Next, we use the same procedure to forecast the dark energy constraints achieveable by the end of the decade, assuming 8 years of WMAP data and realistic projections for ground-based measurements of supernovae and weak lensing. We find the $2 σ$ constraints on the current value of $w$ to be $Δw_0 (2 σ) = 0.20$, and on $dw/dz$ (between $z=0$ and $z=1$) to be $Δw_1 (2 σ)=0.37$. Finally, we compare these limits to other projections in the literature. Most show only a modest improvement; others show a more substantial improvement, but there are serious concerns about systematics. The remaining uncertainty still allows a significant span of competing dark energy models. Most likely, new kinds of measurements, or experiments more sophisticated than those currently planned, are needed to reveal the true nature of dark energy.

description: Generated Jacobian equations are Monge-Ampère type equations which contain optimal transport as a special case. Therefore, optimal transport case has its own special structure which is not necessarily true for more general generated Jacobian equations. Hence the theory for optimal transport can not be directly transplanted to generated Jacobian equations. In this paper, we point out the difficulties that prevent applying the proof the local Hölder regularity of solutions of optimal transport problem from \cite{Loeper2009OnTR} directly to Generated Jacobian Equations, we then discuss how to handle these difficulties, and prove local Hölder regularity in the generated Jacobian equation case.

description: The photon emission by an ultrarelativistic charged particle in extremely strong magnetic field is analyzed, with vacuum polarization and photon recoil taken into account. The vacuum polarization is treated phenomenologically via refractive index. The photon emission occurs in the synergic (cooperative) synchrotron-Cherenkov process [J. Schwinger, W. Tsai and T. Erber, Annals of Physics, 96 303 (1976)] which is similar to the synchrotron emission rather than to the Cherenkov one. For electrons, the effect of the vacuum polarization on the emission spectrum is not evident even beyond the probable onset of non-perturbative quantum electrodynamics (QED). However, the effect of the vacuum polarization on the emission spectrum can be observable for muons already at $γB / B_S \approx 30$, with $γ$ the muon Lorentz factor, $B$ the magnetic field strength and $B_S$ the critical QED field. Nevertheless, vacuum polarization leads to only 10% enhancement of the maximum of the radiation spectrum.

description: We use the exact instanton expansion to illustrate various string characteristics of noncommutative gauge theory in two dimensions. We analyse the spectrum of the model and present some evidence in favour of Hagedorn and fractal behaviours. The decompactification limit of noncommutative torus instantons is shown to map in a very precise way, at both the classical and quantum level, onto fluxon solutions on the noncommutative plane. The weak-coupling singularities of the usual Gross-Taylor string partition function for QCD on the torus are studied in the instanton representation and its double scaling limit, appropriate for the mapping onto noncommutative gauge theory, is shown to be a generating function for the volumes of the principal moduli spaces of holomorphic differentials. The noncommutative deformation of this moduli space geometry is described and appropriate open string interpretations are proposed in terms of the fluxon expansion.

description: We study the fully nonlinear dynamical evolution of binary black hole data, whose orbital parameters are specified via the effective potential method for determining quasi-circular orbits. The cases studied range from the Cook-Baumgarte innermost stable circular orbit (ISCO) to significantly beyond that separation. In all cases we find the black holes to coalesce (as determined by the appearance of a common apparent horizon) in less than half an orbital period. The results of the numerical simulations indicate that the initial holes are not actually in quasi-circular orbits, but that they are in fact nearly plunging together. The dynamics of the final horizon are studied to determine physical parameters of the final black hole, such as its spin, mass, and oscillation frequency, revealing information about the inspiral process. We show that considerable resolution is required to extract accurate physical information from the final black hole formed in the merger process, and that the quasi-normal modes of the final hole are strongly excited in the merger process. For the ISCO case, by comparing physical measurements of the final black hole formed to the initial data, we estimate that less than 3% of the total energy is radiated in the merger process.

description: Providing an accurate evaluation of palm tree plantation in a large region can bring meaningful impacts in both economic and ecological aspects. However, the enormous spatial scale and the variety of geological features across regions has made it a grand challenge with limited solutions based on manual human monitoring efforts. Although deep learning based algorithms have demonstrated potential in forming an automated approach in recent years, the labelling efforts needed for covering different features in different regions largely constrain its effectiveness in large-scale problems. In this paper, we propose a novel domain adaptive oil palm tree detection method, i.e., a Multi-level Attention Domain Adaptation Network (MADAN) to reap cross-regional oil palm tree counting and detection. MADAN consists of 4 procedures: First, we adopted a batch-instance normalization network (BIN) based feature extractor for improving the generalization ability of the model, integrating batch normalization and instance normalization. Second, we embedded a multi-level attention mechanism (MLA) into our architecture for enhancing the transferability, including a feature level attention and an entropy level attention. Then we designed a minimum entropy regularization (MER) to increase the confidence of the classifier predictions through assigning the entropy level attention value to the entropy penalty. Finally, we employed a sliding window-based prediction and an IOU based post-processing approach to attain the final detection results. We conducted comprehensive ablation experiments using three different satellite images of large-scale oil palm plantation area with six transfer tasks. MADAN improves the detection accuracy by 14.98% in terms of average F1-score compared with the Baseline method (without DA), and performs 3.55%-14.49% better than existing domain adaptation methods.

Electron Antineutrino Search at the Sudbury Neutrino Observatory

description: Upper limits on the \nuebar flux at the Sudbury Neutrino Observatory have been set based on the \nuebar charged-current reaction on deuterium. The reaction produces a positron and two neutrons in coincidence. This distinctive signature allows a search with very low background for \nuebar's from the Sun and other potential sources. Both differential and integral limits on the \nuebar flux have been placed in the energy range from 4 -- 14.8 MeV. For an energy-independent ν_e --> \nuebar conversion mechanism, the integral limit on the flux of solar \nuebar's in the energy range from 4 -- 14.8 MeV is found to be Φ_\nuebar <= 3.4 x 10^4 cm^{-2} s^{-1} (90% C.L.), which corresponds to 0.81% of the standard solar model 8B ν_e flux of 5.05 x 10^6 cm^{-2} s^{-1}, and is consistent with the more sensitive limit from KamLAND in the 8.3 -- 14.8 MeV range of 3.7 x 10^2 cm^{-2} s^{-1} (90% C.L.). In the energy range from 4 -- 8 MeV, a search for \nuebar's is conducted using coincidences in which only the two neutrons are detected. Assuming a \nuebar spectrum for the neutron induced fission of naturally occurring elements, a flux limit of Phi_\nuebar <= 2.0 x 10^6 cm^{-2} s^{-1}(90% C.L.) is obtained.

description: Das Thema dieser Diplomarbeit beschäftigt sich mit der Schaffung eines neuen Wohnquartiers in der Stadt Mostar, Bosnien-Herzegowina. Das zentral gelegene Grundstück besitzt ein Ausmaß von ca. 2,2 ha. Es setzt sich zusammen aus einer nicht bebauten Fläche sowie einem flächenmäßig dreimal so großem bebauten Areal. Dieses ist geprägt von einem für die Stadt bedeutenden öffentlichen Platz, der eine Einheit mit dem historisch geprägten Kulturzentrum bildet, das aufgrund seines kulturellen Nutzens, für die Bevölkerung und das Stadtbild ausgebaut und revitalisiert wird. Vis-a-vis des zu planenden Bauplatzes befindet sich der größte städtische Park der als ein beliebter Treffpunkt der Bewohnerinnen fungiert. Dadurch wird er ein maßgeblichen Einfluss auf das planende Gebiet haben. Die Herausforderung liegt an der Umsetzung eines für die Stadt zukunftsorientierten durchgemischten Wohnquartiers unter Bezug auf die bestehenden Einflussfaktoren und städtebaulichen Gegebenheiten. Ziel ist es eine höhere Wohnzufriedenheit unter den unterschiedlichen Nutzergruppen und eine Erhöhung der Lebensqualität und des Standards zu schaffen.
description: This thesis deals with establishmentof a new residental area in the city of Mostar, Bosnia and Herzegovina. The central portion extends over the area of approx. 2,2 ha. It consists of an unbuilt surface, as well as an existing surface area that is three times as large. This area is embossed with one of the city`s most significant opened spaces, that forms unity together with historically imprinted cultural center. Due to creating a better and prettier surrounding, this area is being revitalized. Next to the planned building site is also the biggest city park, know as the most popular meeting point in the city. Therefore there will be a significant influence on the planned residential area. The challenge lies in the implementation of this future-oriented residential area, considering the existing factors and mixed neighbourhoods surrounding it. The aim is to achieve a higher satisfaction with the surrounding environment for all groups of users and an increase in life quality and standards.

description: We consider the dynamics of the photon states in distant resonators coupled to a common bus resonator at different positions. The frequencies of distant resonators from a common bus resonator are equally detuned. These frequency detunings are kept larger than the coupling strengths of each resonator to the common bus resonator to satisfy the dispersive interaction regime. In the dispersive regime, we show that the time dynamics of the system evolve to an arbitrary W-type state in a single step at various interaction times. Our results show that a one-step generation of arbitrary W-type states can be achieved with high fidelity in a system of superconducting resonators.
