description: This treatise explores the history of belting, the differences in types of belting, belting registers, exploring a methodology of healthy, and stylistically correct belt. The ability to sing musical theatre style has become high in demand from both Broadway and Opera companies. About more than half of Young Artist Programs, pay to sings, and apprenticeships put on at least one musical theater show a season. Those on the audition panel now ask in the audition requirements for at least one musical theatre piece to perform for them. Having the knowledge of how to properly belt will help the performer have more opportunities than other singers who only know how to sing bel canto style. This treatise will include a new methodology that will address a belting technique through the lens of a classically trained singer and how to transfer elements from bel canto technique into a belting technique. The questions that will be addressed in this treatise are as follows: 1. What quality and stylistic elements does belting require? 2. What is the difference between the contemporary commercial music methodology (CCM) and musical theatre methodology on belting? 3. Why is it important to learn how to belt as a classical singer? The author will answer these questions by providing information from sources of both professional teachers in the classical singer industry as well as professional teachers in the musical theater industry. Proper vocal exercises with detailed instructions are also provided to help the classically trained singer navigate their voice in belting. The relevance of this topic is very strong right now, this is a need that people are trying to educate themselves by watching Youtube tutorials, reading inaccurate literature on belting, and trying to do it on their own with no proper knowledge on the subject. If belting improperly, a singer is susceptible to injuring their voice. It is time to break the myths and cautions on belting and make it known that there is a healthy and stylistically appropriate way to belt.

description: High resolution magnetization measurements performed in a high quality Ba_(1-x)K_xFe2As2 single crystal allowed to determine the diamagnetism induced above the superconducting transition by thermally activated Cooper pairs. These data, obtained with magnetic fields applied along and transverse to the crystal ab layers, demonstrate experimentally that the superconducting transition of iron pnictides may be explained at a phenomenological level in terms of the Gaussian Ginzburg-Landau approach for three-dimensional anisotropic superconductors.

description: We introduce a way of presentation of pairs $(E,\nabla)$, where $E$ is a bundle on a Riemann surface and $\nabla$ is a logarithmic connection in $E$, which is based on a presentation of the surface as a factor of the exterior of the unit disc. In this presentation we write the local equation of isomonodormic deformation of pairs $(E,\nabla)$. These conditions are written as a modified Schlesinger system on a Riemann sphere (and in the typical case just as an ordinary Schlesinger system) plus some linear system.

description: Megabar pressures are of crucial importance for cutting-edge studies of condensed matter physics and geophysics. With the development of diamond anvil cell, laboratory studies of high pressure have entered the megabar era for decades. However, it is still challenging to implement in-situ magnetic sensing under ultrahigh pressures. Here, we demonstrate optically detected magnetic resonance of diamond nitrogen-vacancy (NV) centers, a promising quantum sensor of strain and magnetic fields, up to 1.4 Mbar. We quantify the reduction and blueshifts of NV fluorescence under high pressures. We demonstrate coherent manipulation of NV electron spins and extend its working pressure to the megabar region. These results shed new light on our understanding of diamond NV centers and will benefit quantum sensing under extreme conditions.

description: It is shown that the square of the Dirac Hamiltonian with the isotropic mass-hedgehog potential in d dimensions is the number operator of fictitious bosons and fermions over d quantum states. This result allows one to obtain the complete spectrum and degeneracies of the Dirac Hamiltonian with the hedgehog mass configuration in any dimension. The result pertains to low-energy states in the core of a general superconducting or insulating vortex in graphene in two dimensions, and in the superconducting vortex at the topological - trivial insulator interface in three dimensions, for example. The spectrum in d=2 is also understood in terms of the underlying accidental SU(2) symmetry and the supersymmetry of the Hamiltonian.

description: Multivariable, real-valued functions induce matrix-valued functions defined on the space of d-tuples of n-times-n pairwise-commuting self-adjoint matrices. We examine the geometry of this space of matrices and conclude that the best notion of differentiation of these matrix-valued functions is differentiation along curves. We prove that a C^1 real-valued function always induces a C^1 matrix function and give an explicit formula for the derivative. We also show that every real-valued C^m function defined on an open rectangle in the plane induces a matrix-valued function that can be m-times continuously differentiated along C^m curves.

description: We study the most general case of spherically symmetric vacuum solutions in the framework of the Covariant Horava Lifshitz Gravity, for an action that includes all possible higher order terms in curvature which are compatible with power-counting normalizability requirement. We find that solutions can be separated into two main classes: (i) solutions with nonzero radial shift function, and (ii) solutions with zero radial shift function. In the case (ii), spherically symmetric solutions are consistent with observations if we adopt the view of Horava and Melby-Tomson, according to which the auxiliary field A can be considered as a part of an effective general relativistic metric, which is valid only in the IR limit. On the other hand, in the case (i), consistency with observations implies that the field A should be independent of the spacetime geometry, as the Newtonian potential arises from the nonzero radial shift function. Also, our aim in this paper is to discuss and compare these two alternative but different assumptions for the auxiliary field A.

description: In dieser Arbeit wird der Erstkontakt von eingewanderten Familien bei Stellen, die in der Erziehungsberatung und insbesondere im Frühbereich tätig sind, untersucht. In der sogenannten Frühen Kindheit treffen Eltern mit ihren Kindern meistens zum ersten Mal auf Fachleute, die sich beruflich mit Familienthemen beschäftigen. Die wiederum begegnen Menschen, in einer zunehmend vielfältigen Welt, die unterschiedliche und andere Lebensweisen haben und die ihr gewohntes Umfeld verlassen mussten. Diese empfundene Ungleichheit wird im Kontakt und in der Beratung oft als besonders herausfordernd erlebt. Das umso mehr, wenn die Unterschiede, zum Beispiel aufgrund anderer Sprache oder anderem Aussehen, vermeintlich stärker hervortreten. Es wird festgestellt, dass dem Erstkontakt und ersten Gespräch mit eingewanderten Familien daher eine grosse Bedeutung zukommt. Wenn es schon beim Kennenlernen zu Irritationen und Missverständnissen kommt, ist der Kontakt von Anfang an erschwert oder es droht ein Abbruch der Beratung. Um dem entgegenzuwirken wird die Einschätzung gemacht, dass es eine Offenheit braucht gegenüber verschiedenen Lebenswirklichkeiten, damit Verständnis und Vertrauen entstehen kann. Das Ziel ist mit systemischen und interkulturellen Ansätzen und Überlegungen auf den Erstkontakt mit eingewanderten Familien zu blicken, um somit neue Erkenntnisse hinsichtlich des Aufbaus einer «sicheren» Zusammenarbeit zu gewinnen. Ich mache das, indem ich bestehende Fachliteratur vergleiche und Aussagen zur interkulturellen Dimension und zu beraterischen Grundsätzen und Vorgehensweisen im Erstkontakt und –gespräch formuliere. Zudem nehme ich Bezug mit kurzen Fallbeispielen auf die Praxis in einer Frühförderstelle. Ich ziehe zum Schluss die Folgerung und die Erkenntnis, dass es, neben grundlegenden fachlichen und persönlichen Kompetenzen, vor allem die Beschäftigung mit gesellschaftlichen Gegebenheiten und Zusammenhängen und die Auseinandersetzung mit der individuellen und sozioökonomischen Realität des Einzelnen braucht, um in einen guten ersten Kontakt mit den Familien zu kommen. Mit dem Ziel, dass die Eltern mit ihren Kindern das Angebot einer Beratungs- und Frühförderstelle nutzen und Vertrauen gewinnen in die Fachleute sowie in ihre eigenen Möglichkeiten.
On variables with few occurrences in conjunctive normal forms

description: We consider the question of the existence of variables with few occurrences in boolean conjunctive normal forms (clause-sets). Let mvd(F) for a clause-set F denote the minimal variable-degree, the minimum of the number of occurrences of variables. Our main result is an upper bound mvd(F) <= nM(surp(F)) <= surp(F) + 1 + log_2(surp(F)) for lean clause-sets F in dependency on the surplus surp(F). - Lean clause-sets, defined as having no non-trivial autarkies, generalise minimally unsatisfiable clause-sets. - For the surplus we have surp(F) <= delta(F) = c(F) - n(F), using the deficiency delta(F) of clause-sets, the difference between the number of clauses and the number of variables. - nM(k) is the k-th "non-Mersenne" number, skipping in the sequence of natural numbers all numbers of the form 2^n - 1. We conjecture that this bound is nearly precise for minimally unsatisfiable clause-sets. As an application of the upper bound we obtain that (arbitrary!) clause-sets F with mvd(F) > nM(surp(F)) must have a non-trivial autarky (so clauses can be removed satisfiability-equivalently by an assignment satisfying some clauses and not touching the other clauses). It is open whether such an autarky can be found in polynomial time. As a future application we discuss the classification of minimally unsatisfiable clause-sets depending on the deficiency.

description: The paper interprets the cubic nonlinear Schrödinger equation as a Hamiltonian system with infinite dimensional phase space. There is a Gibbs measure which is invariant under the flow associated with the canonical equations of motion. The logarithmic Sobolev and concentration of measure inequalities hold for the Gibbs measures, and here are extended to the $k$-point correlation function and distributions of related empirical measures. By Hasimoto's theorem, NLSE gives a Lax pair of coupled ODE for which the solutions give a system of moving frames. The paper studies the evolution of the measure induced on the moving frames by the Gibbs measure.
Deconstructing democratisation: an ethnographic analysis of independent/DIY music work in Wellington, Aotearoa/New Zealand

description: This thesis is an investigation and critique of the claims propagated by discourses of democratisation through an ethnographic analysis of independent/DIY musicians and music scenes in Wellington, Aotearoa/New Zealand. Where democratisation envisions an idealised entrepreneurial subject, I contextualise the conditions of independent musical labour to unveil the ongoing and pervasive presence of industry hierarchies, biases, and power dynamics. As a nation typically characterised by its peripherality to major centres of cultural production, Aotearoa/New Zealand presents unique investigation opportunities. Digital tools promised to collapse the tyranny of distance, incorporating Aotearoa/New Zealand musicians into global music industries. Furthermore, popular music production has been deployed as a resource for economic generation and national identity construction under a third-way regime, with the state playing a salient role in moulding contemporary conditions of musical labour. 
Contrary to a rhetoric of empowerment and autonomy, this thesis reveals how those tools of democratisation – streaming platforms, social media platforms, state arts initiatives, and so on – reinforce unsustainable labour conditions and normalise the precarious labour subject. I position the so-called democratised musician within a web of commercial, political, and technological structures, probing the intersection of these structures and musical practice to unveil how Wellington’s independent/DIY musicians internalise, embody, and navigate the trope of the democratised entrepreneur. However, I am not just concerned with the independent musician as a precarious subject trapped within discriminatory power structures, but with how independent/DIY musicians engage with and manipulate these conditions to forge sustainable practice. Accordingly, this thesis illuminates the creative and innovative methods used to alleviate precarity, with collective practices acting as a counterbalance the inherent risks of the independent, entrepreneurial ideal.

description: We investigate the effective long-range interactions between intruder particles immersed in a randomly driven granular fluid. The effective Casimir-like force between two intruders, induced by the fluctuations of the hydrodynamic fields, can change its sign when varying the control parameters: the volume fraction, the distance between the intruders, and the restitution coefficient. More interestingly, by inserting more intruders, we verify that the fluctuation-induced interaction is not pairwise additive. The simulation results are qualitatively consistent with the theoretical predictions based on mode coupling calculations. These results shed new light on the underlying mechanisms of collective behaviors in fluidized granular media.

We start with an E_6 singularity unfolded from an E_8 singularity and obtain E_6 GUTs by using an SU(3) spectral cover. By turning on SU(2) X U(1)^2 gauge fluxes, we obtain a rank 5 model with the gauge group SU(3) X SU(2) X U(1)^2. Based on the well-studied geometric backgrounds in the literature, we demonstrate several models and discuss their phenomenology.

Towards a holographic universe
Creators: name: Sahu, Abhisek
Publisher: name: University of British Columbia
Year: 2022

description: In this thesis, we present a bottom-up holographic model for a large class of time- reversal symmetric cosmological spacetimes, through the anti-de Sitter/conformal field theory (AdS/CFT) correspondence. A major challenge in describing cosmological spacetimes using the AdS/CFT correspondence, is that they often do not have an anti-de Sitter (AdS) boundary. To solve this problem we have constructed a geometry by embedding spherically symmetric regions of a Friedmann-Lemaître-Robertson-Walker (FLRW) spacetime with a given scale factor inside a Schwarzschild-AdS (SAdS) spacetime, with the simple assumption that the two regions are separated by a thin shell satisfying Israel junction conditions. To ensure there exists a quantum state in the conformal field theory (CFT) which is dual to the bulk spacetime, we consider only time-reversal symmetric bubble spacetimes. This property allows us to define a real Euclidean spacetime by analytically continuing to imaginary times. We show that in certain cases, the Euclidean spacetime with its non-trivial asymptotic structure in form of the combined Euclidean AdS boundary of the FLRW cosmology and the SAdS boundary, gives rise to a natural state of the CFT via a Euclidean path integral. We also demonstrate the embedding procedure and existence of non-trivial asymptotics through some explicit examples. At this point two significant complications may arise. Firstly, to have the Euclidean asymptotics and time-reversal symmetry discussed above, we need cosmologies with a fundamentally negative cosmological constant, Λ. We argue that although the Λ-cold dark matter (ΛCDM) model points towards a small positive Λ, there is a plausible path forward with a model with a time dependent scalar field with a potential that is currently positive, but rolling towards a negative value to give us an effective negative Λ. Secondly, it is possible that our bubble lies behind the horizon of the SAdS black hole where we typically can’t probe. This problem is solved by a thorough analysis of the model’s parameter space, which suggests there is always a large set of parameters allowing embedding arbitrarily large bubbles of cosmology that peek out of the horizon.
Den æstetiske dannelse og formativ vurdering

Publisher: name: CEPRA-striben
Year: 2019

description: Artiklen tager udgangspunkt i en pædagogisk filosofisk udforskning af æstetikkens dannelsespotentiale gennem et litteraturstudie. Udgangspunktet er, at dette syn på dannelse ikke alene knytter an til elevernes forhold til sig selv; men også til deres forhold til omverdenen og det sociale fællesskab. Det diskuteres, hvordan æstetisk aktivitet kræver strategier i anvendelse af formative vurdering gennem en model for æstetisk basiskompetence. Denne model er funderet i pædagogisk filosofi. Modellen har fire sammenhængende felter: Skabe, udøve, opleve og vurdere. At skabe sætter fokus på elevernes evne til at formgive i forskellige sammenhænge. At udøve drejer sig om æstetisk praksis, hvor eleverne øver sig i at formidle en æstetisk idé. At skabe og udøve er centralt for kunstdidaktikken. At opleve og vurdere er centralt for udvikling af et kognitivt perspektiv. Refleksion over disse fire sammenhængende felter antages at kunne udvikles gennem anvendelsen af løbende formativ vurdering. Den æstetiske dannelse og den æstetiske basiskompetence handler derfor om deltagelse og kommunikation i praksis. Den æstetiske basiskompetence kan fremmes gennem formativ vurdering – er antagelsen i denne artikel.

Dural venous sinuses distortion and compression with supratentorial mass lesions: a mechanism for refractory intracranial hypertension?
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo
Year: 2023

description: Objective—To determine the effect of supratentorial intraparenchymal mass lesions of various volumes on dural venous sinuses structure and transluminal pressures. Methods—Three set of preparations were made using adult isolated head derived from fresh human cadaver. A supratentorial intraparenchymal balloon was introduced and inflated at various volumes and effect on dural venous sinuses was assessed by serial intravascular ultrasound, computed tomographic (CT), and magnetic resonance (MR) venograms. Contrast was injected through a catheter placed in sigmoid sinus for both CT and MR venograms. Serial trasluminal pressures were measured from middle part of superior sagittal sinus in another set of experiments. Results—At intraparenchymal balloon inflation of 90 cm3 , there was attenuation of contrast enhancement of superior sagittal sinus with compression visualized in posterior part of the sinus without any evidence of compression in the remaining sinus. At intraparenchymal balloon inflation of 180 and 210 cm3 , there was compression and obliteration of superior sagittal sinus throughout the length of the sinus. In the coronal sections, at intraparenchymal balloon inflations of 90 and 120 cm3 , compression and obliteration of the posterior part of superior sagittal sinus were visualized. In the axial images, basal veins were not visualized with intraparenchymal balloon inflation of 90 cm3 or greater although straight sinus was visualized at all levels of inflation. Trasluminal pressure in the middle part of superior sagittal sinus demonstrated a mild increase from 0 cm H2O to 0.4 cm H2O and 0.5 cm H2O with inflation of balloon to volume of 150 and 180 cm3 , respectively. There was a rapid increase in transluminal pressure from 6.8 cm H2O to 25.6 cm H2O as the supratentorial mass lesion increased from 180 to 200 cm3 . Conclusions—Our experiments identified distortion and segmental and global obliteration of dural venous sinuses secondary to supratentorial mass lesion and increase in transluminal pressure with large volume lesions. The secondary involvement of dural venous sinuses may represent a mechanism for refractory intracranial hypertension

description: We consider a general five-dimensional sigma-model coupled to gravity, with any number of scalars and general sigma-model metric and potential. We discuss in detail the problem of the boundary conditions for the scalar fluctuations, in the case where the fifth dimension is compact, and provide a simple (and very general) algorithmic procedure for computing the spectrum of physical scalar fluctuations of the fully back-reacted system. Focusing in particular on the conditions under which the spectrum of scalar excitations (glueballs) contains parametrically light states, we apply the formalism to some especially simple toy models, which can be thought of as the gauge/gravity duals of strongly-coupled, non-conformal four-dimensional gauge theories. Our examples are chosen both within the context of phenomenological effective field theory constructions (bottom-up approach), and within the context of consistent truncations of ten-dimensional string theories in the supergravity limit (top-down approach). In one of the examples, a light dilaton is present in the spectrum in spite of the presence of a bad naked singularity in the deep IR, near which the RG flow of the dual theory is certainly very far away from any fixed point. If this feature were to persist in a complete model in which the singularity is resolved, this would prove that a light dilaton is to be expected in at least certain walking technicolor theories. We provide here all the technical details for testing this statement, once such a complete model is identified.

We examine the effects of a nominalist disposition on historiography, teaching, and research.

Safe optimization developments and applications

Publisher: name: University of British Columbia

description: In many machine learning problems, an objective is required to be optimized with respect to some constraints. In many cases, these constraints are unknown to us but we can search and take measurements within an exploration radius. In the machine learning community, we call this safe optimization. One important point in safe optimization algorithms is how fast we can converge to optima and get in a neighborhood of the optimal solution. In this thesis, we introduce a novel safe optimization algorithm that is fast. The experiments are performed through a software package we developed called ASFW which is available for download. On the application side, we demonstrate how safe optimization techniques can be applied to a real-world problem and make an attempt to employ safe optimization approaches to solve a real-world problem and propose a frame work that may be applied in various industrial settings.

description: In this article we generalize the Bohr-Sommerfeld rule for scalar symbols at a potential well to matrix-valued symbols having eigenvalues that may coalesce precisely at the bottom of the well.

description: Due to the unfavorable scaling of tensor network methods with the refinement parameter M, new approaches are necessary to improve the efficiency of numerical simulations based on such states in particular for gapless, strongly entangled systems. In one-dimensional DMRG, the use of Abelian symmetries has lead to large computational gain. In higher-dimensional tensor networks, this is associated with significant technical efforts and additional approximations. We explain a formalism to implement such symmetries in two-dimensional tensor network states and present benchmark results that confirm the validity of these approximations in the context of projected entangled-pair state algorithms.

description: Let $σ$ be a permutation of a nonempty finite or countably infinite set $X$ and let $F_X\left( σ^k\right)$ count the number of fixed points of the $k$th power of $σ$. This paper explains how the arithmetic function $k \mapsto \left(F_X\left( σ^k\right) \right)_{k=1}^{\infty}$ determines the conjugacy class of the permutation $σ$, constructs an algorithm to compute the conjugacy class from the fixed point counting function $F_X\left( σ^k\right)$, and describes the arithmetic functions that are fixed point counting functions of permutations.

The effect of a massive object on an expanding universe

description: A tetrad-based procedure is presented for solving Einstein's field equations for spherically-symmetric systems; this approach was first discussed by Lasenby et al. in the language of geometric algebra. The method is used to derive metrics describing a point mass in a spatially-flat, open and closed expanding universe respectively. In the spatially-flat case, a simple coordinate transformation relates the metric to the corresponding one derived by McVittie. Nonetheless, our use of non-comoving (`physical') coordinates greatly facilitates physical interpretation. For the open and closed universes, our metrics describe different spacetimes to the corresponding McVittie metrics and we believe the latter to be incorrect. In the closed case, our metric possesses an image mass at the antipodal point of the universe. We calculate the geodesic equations for the spatially-flat metric and interpret them. For radial motion in the Newtonian limit, the force acting on a test particle consists of the usual $1/r^2$ inwards component due to the central mass and a cosmological component proportional to $r$ that is directed outwards (inwards) when the expansion of the universe is accelerating (decelerating). For the standard $Λ$CDM concordance cosmology, the cosmological force reverses direction at about $z\approx 0.67$. We also derive an invariant fully general-relativistic expression, valid for arbitrary spherically-symmetric systems, for the force required to hold a test particle at rest relative to the central point mass.

description: I use quaternion free probability calculus - an extension of free probability to non-Hermitian matrices (which is introduced in a succinct but self-contained way) - to derive in the large-size limit the mean densities of the eigenvalues and singular values of sums of independent unitary random matrices, weighted by complex numbers. In the case of CUE summands, I write them in terms of two "master equations," which I then solve and numerically test in four specific cases. I conjecture a finite-size extension of these results, exploiting the complementary error function. I prove a central limit theorem, and its first sub-leading correction, for independent identically-distributed zero-drift unitary random matrices.

description: This article examines instructional coaches in the context of The Danish National Tests. Drawing on survey data collected from nine municipalities, which all have increased their focus on The Danish National Tests, the article examines the degree of knowledge the instructional coaches possess and the extent to which they use the test in their work. It is found, that instructional coaches, who works in the investigated municipalities, generally have knowledge about the tests. They do also overall use the test in several key areas as coaches for their co-teachers. Instructional coaches can have a positive influence on the use of data among their co-teachers, which can lead to changes in their practice and benefit pupil’s achievements.

description: We present some astrophysical consequences of the metric for a point mass in an expanding universe derived in Nandra, Lasenby & Hobson, and of the associated invariant expression for the force required to keep a test particle at rest relative to the central mass. We focus on the effect of an expanding universe on massive objects on the scale of galaxies and clusters. Using Newtonian and general-relativistic approaches, we identify two important time-dependent physical radii for such objects when the cosmological expansion is accelerating. The first radius, $r_F$, is that at which the total radial force on a test particle is zero, which is also the radius of the largest possible circular orbit about the central mass $m$ and where the gas pressure and its gradient vanish. The second radius, $r_S$, which is \approx r_F/1.6$, is that of the largest possible stable circular orbit, which we interpret as the theoretical maximum size for an object of mass $m$. In contrast, for a decelerating cosmological expansion, no such finite radii exist. Assuming a cosmological expansion consistent with a $Λ$CDM concordance model, at the present epoch we find that these radii put a sensible constraint on the typical sizes of both galaxies and clusters at low redshift. For galaxies, we also find that these radii agree closely with zeroes in the radial velocity field in the neighbourhood of nearby galaxies, as inferred by Peirani & Pacheco from recent observations of stellar velocities. We then consider the future effect on massive objects of an accelerating cosmological expansion driven by phantom energy, for which the universe is predicted to end in a `Big Rip' at a finite time in the future at which the scale factor becomes singular. In particular, we present a novel calculation of the time prior to the Big Rip that an object of a given mass and size will become gravitationally unbound.
