description: Inspired by special and general relativistic systems that can have Hamiltonians involving square roots, or more general fractional powers, in this article we address the question how a suitable set of coherent states for such systems can be obtained. This becomes a relevant topic if the semiclassical sector of a given quantum theory wants to be analysed. As a simple setup we consider the toy model of a deparametrised system with one constraint that involves a fractional power of the harmonic oscillator Hamiltonian operator and we discuss two approaches for finding suitable coherent states for this system. In the first approach we consider Dirac quantisation and group averaging that have been used by Ashtekar et. al. but only for integer powers of operators. Our generalisation to fractional powers yields in the case of the toy model a suitable set of coherent states. The second approach is inspired by coherent states based on a fractional Poisson distribution introduced by Laskin, which however turn out not to satisfy all properties to yield good semiclassical results for the operators considered here and in particular do not satisfy a resolution of identity as claimed. Therefore, we present a generalisation of the standard harmonic oscillator coherent states to states involving fractional labels, which approximate the fractional operators in our toy model semiclassically more accurately and satisfy a resolution of identity. In addition, motivated by the way the proof of the resolution of identity is performed, we consider these kind of coherent states also for the polymerised harmonic oscillator and discuss their semiclassical properties

description: An L-factor of a graph G is a spanning subgraph of G whose every component is a 3-vertex path. Let v(G) be the number of vertices of G and d(G) the domination number of G. A claw is a graph with four vertices and three edges incident to the same vertex. A graph is claw-free if it has no induced subgraph isomorphic to a claw. Our results include the following. Let G be a 3-connected claw-free graph, x a vertex in G, e = xy an edge in G, and P a 3-vertex path in G. Then (a1) if v(G) = 0 mod 3, then G has an L-factor containing (avoiding) e, (a2) if v(G) = 1 mod 3, then G - x has an L-factor, (a3) if v(G) = 2 mod 3, then G - {x,y} has an L-factor, (a4) if v(G) = 0 mod 3 and G is either cubic or 4-connected, then G - P has an L-factor, (a5) if G is cubic with v(G) > 5 and E is a set of three edges in G, then G - E has an L-factor if and only if the subgraph induced by E in G is not a claw and not a triangle, (a6) if v(G) = 1 mod 3, then G - {v,e} has an L-factor for every vertex v and every edge e in G, (a7) if v(G) = 1 mod 3, then there exist a 4-vertex path N and a claw Y in G such that G - N and G - Y have L-factors, and (a8) d(G) < v(G)/3 +1 and if in addition G is not a cycle and v(G) = 1 mod 3, then d(G) < v(G)/3. We explore the relations between packing problems of a graph and its line graph to obtain some results on different types of packings. We also discuss relations between L-packing and domination problems as well as between induced L-packings and the Hadwiger conjecture. Keywords: claw-free graph, cubic graph, vertex disjoint packing, edge disjoint packing, 3-vertex factor, 3-vertex packing, path-factor, induced packing, graph domination, graph minor, the Hadwiger conjecture.

description: We explore the adiabatic particle excitations of an interacting field in a cosmological background. By following the time-evolution of the quantum state corresponding to the particle excitation, we show how the basic properties characterizing the particle propagation can be recovered from the two-point propagators. As an application, we study the background-induced dissipative effects on the propagation of a two-level atom in an expanding universe.

description: A quantum dot fabricated by scanning probe oxidation lithography on a p-type, C-doped GaAs/AlGaAs heterostructure is investigated by low temperature electrical conductance measurements. Clear Coulomb blockade oscillations are observed and analyzed in terms of sequential tunneling through the single-particle levels of the dot at T_hole = 185 mK. The charging energies as large as 2 meV evaluated from Coulomb diamond measurements together with the well resolved single-hole excited state lines in the charge stability diagram indicate that the dot is operated with a small number of confined particles close to the ultimate single-hole regime.

Pfaffian point process for the Gaussian real generalised eigenvalue problem

description: The generalised eigenvalues for a pair of $N\times N$ matrices $(X_1,X_2)$ are defined as the solutions of the equation $\det (X_1-λX_2)=0$, or equivalently, for $X_2$ invertible, as the eigenvalues of $X_2^{-1}X_1$. We consider Gaussian real matrices $X_1,X_2$, for which the generalised eigenvalues have the rotational invariance of the half-sphere, or after a fractional linear transformation, the rotational invariance of the unit disk. In these latter variables we calculate the joint eigenvalue probability density function, the probability $p_{N,k}$ of finding $k$ real eigenvalues, the densities of real and complex eigenvalues (the latter being related to an average over characteristic polynomials), and give an explicit Pfaffian formula for the higher correlation functions $ρ_{(k_1,k_2)}$. A limit theorem for $p_{N,k}$ is proved, and the scaled form of $ρ_{(k_1,k_2)}$ is shown to be identical to the analogous limit for the correlations of the eigenvalues of real Gaussian matrices. We show that these correlations satisfy sum rules characteristic of the underlying two-component Coulomb gas.

description: Reverse biasing triple-junction GaInP/Ga(In)As/Ge solar cells may affect their performance by the formation of permanent shunts even if the reverse breakdown voltage is not reached. In previous works, it was observed that, amid the three components, GaInP subcells are more prone to degrade when reverse biased suffering permanent damage, although they present an initial good performance. The aim of this work is, firstly, to study the characteristics of the defects that cause the catastrophic failure of the devices. For this, GaInP isotype solar cells were analysed by visual inspection and electroluminescence maps and submitted to reverse bias stress test. We find that specific growth defects (i.e. hillocks), when covered with metal, cause the degradation in the cells. SEM cross-section imaging and EDX compositional analysis of these defects reveal their complex structures, which in essence consist of material abnormally grown on and around particles present on the wafer surface before growth. The reverse bias stress test is proposed as a screening method to spot defects hidden under the metal that may not be detected by conventional screening methods. By applying a quick reverse bias stress test, we can detect those defects that cause the degradation of devices at voltages below the breakdown voltage and that may also affect their long-term reliability.

description: In this study, the transit observations of HAT-P-16b and TrES-3b exoplanets were carried out at ÇÜ UZAYMER Observatory with a 50 cm Ritchey Chretien type telescope. By analyzing the light curves of both exoplanets, system parameters have been obtained with acceptable models. Some of these parameters for HAT-P-16 systems were found to be: M$_{P}$=4.172$\pm$0.163 M$_{J}$, R$_{P}$=1.309$\pm$0.111 R$_{J}$, a/R$_{*}$=7.1922$\pm$0.0017 and b=0.1003$\pm$0.1533 which are consistent with the values given in \cite{2010ApJ...720.1118B}. Also, for the TrES-3 system, the same parameters were calculated as M$_{P}$=1.959$\pm$0.111 M$_{J}$, R$_{P}$=1.320$\pm$0.169 R$_{J}$, a/R$_{*}$=6.0656$\pm$ 0.4899 and b=0.7892$\pm$0.0700. These values are also consistent with the values given in \cite{2007ApJ...663L..37O}. No significant Transit Timing Variations (TTV) was found as a result of the Lomb-Scargle (LS) periodogram for HAT-P-16b by using the transit times obtained from the transit light curves (False Alarm Probabilities -- FAP) = \%96). However, a significant periodicity was found at 32.38 days and a secondary periodicity was found at 41.07 days were determined as a result of the LS periodogram obtained from the TrES-3b data. We interpret that these periods with FAP of 3.41 \% and 1.88 \%, respectively, are close to the rotation period of the host star. Therefore, these periods could be due to the modulation of spot-induced light variations.

Personality and direct assessment of behaviour
Creators: name: Violato, Claudio
Publisher: name: University of British Columbia
Year: 2010

description: The primary purpose of the present study was to develop the thesis that conventional personality psychology has reached its limits as a science and that an alternative approach is both called for and contrivable. Accordingly, the two major classes of personality models — the trait and psycliodynamic models — were critically analyzed in terms of conceptual, methodological and empirical considerations. Situationism, — the antithesis of the trait and psychodynamic models with respect to causality — was examined on the same bases. And finally, interactionism (the model which attempts to incorporate features of both of the former positions) was critically analyzed. It was concluded that some fundamental and crucial shortcomings in these conventional personality psychology positions, have caused personality psychology as a science to have reached its limits. Accordingly, an alternative approach based on direct assessment of behaviour which may provide a basis for the amelioration of the: difficulties that apparently inhere in the former positions, was proposed. More specifically, a personality dimension based on accumulated evidence was suggested and of particular concern was the extent to which people consistently manifest behaviour which can justify the postulation of two behavioural orientations, styles or personality types. An empirical investigation of the transsituational consistency of persistence of behaviour of elementary school children was reported. The results generally supported the hypothesis that the direct assessment of behaviour across varied situations will show higher transsituational consistency of behaviour than the usual indirect assessment procedures have heretofore indicated. The implications of this approach both for the consistency-specificity issue and personality assessment in general, were discussed.

description: Optimal control theory is applied to analyze the time-optimal solution with a single scalar control knob in a two-level quantum system without quantum decoherence. Emphasis is \change{placed} on the dependence on the maximum control strength $u_\text{max}$. General constraints on the optimal protocol are derived and used to rigorously parameterize the time-optimal solution. Two concrete problems are investigated. For generic state preparation problems, both multiple bang-bang and bang-singular-bang are legitimate and should be considered. Generally, the optimal is bang-bang for small $u_\text{max}$, and there exists a state-dependent critical amplitude above which singular control emerges. For the X-gate operation of a qubit, the optimal protocol \change{is exclusively} multiple bang-bang. The minimum gate time is about 80\% of that based on the resonant Rabi $π$-pulse over a wide range of control strength; in the $u_\text{max} \rightarrow 0$ limit this ratio is derived to be $π/4$. To develop practically feasible protocols, we present methods to smooth the abrupt changes in the bang-bang control while preserving perfect gate fidelity. \change{The presence of bang-bang segments in the time-optimal protocol} indicates that the high-frequency components and a full calculation (instead of the commonly adopted Rotating Wave Approximation) are essential for the ultimate quantum speed limit.

description: Benchmarks are standardized validation frameworks that allow for the direct comparison of various models that address the same research problem. In benchmarks, predefined evaluation criteria (metrics) are used to compare how well different methods can predict an outcome variable (truth criterion) given the predictors (data) at hand. The use of benchmarks has touched many fields of science including computer and data science, physics, biomedicine, and the humanities. Participants are invited to submit their models to the benchmark, which is commonly referred to as organizing a challenge. Other frequently used terms are shared or common tasks and competitions. Within the ODISSEI benchmarking task, benchmarks were introduced in the social sciences. Funded by ODISSEI and an NWO VIDI grant awarded to Gert Stulp (RUG), Eyra developed an open source benchmark infrastructure starter kit. A fertility prediction challenge that will be organized by Elizaveta Sivak and Gert Stulp will function as a pilot for the infrastructure. A first version of the infrastructure has been released on the Next platform. An open source web platform with re-usable modules developed by Eyra that functions as an integration hub for various software-as-a-service solutions that empower science and support the workflow of researchers. This first version was tested during the SICSS – ODISSEI Summer School 2023 with a fertility prediction pilot challenge using LISS panel data provided by Centerdata. This presentation, presents the infrastructure and discusses lessons learned from the summer school pilot and plans for future developments.

description: We examine the biases induced on cosmological parameters when the presence of secondary anisotropies is not taken into account in Cosmic Microwave Background analyses. We first develop an exact analytical expression for computing the biases on parameters when any additive signal is neglected in the analysis. We then apply it in the context of the forthcoming Planck experiment. For illustration, we investigate the effect of the sole residual thermal Sunyaev--Zel'dovich signal that remains after cluster extraction. We find in particular that analyses neglecting the presence of this contribution introduce on the cosmological parameters n_s and tau biases, at least 6.5 and 2.9 times their one sigma confidence intervals. The Omega_b parameter is also biased to a lesser extent.

description:
      Formålet med projektet er at gennemføre en effekt- og procesevaluering af 5 kommunale interventioner vedrørende tilbagevenden til arbejde blandt langtidssygemeldte borgere.

      Med hensyn til effektevalueringen skal projektet være i stand til at besvare følgende spørgsmål:

      - Fører interventionen til tidligere tilbagevenden til arbejde?

      - Fører interventionen til mindre sygefravær i opfølgningsperioden?

      - Fører interventionen til en forbedret arbejdsevne?

      - Fører interventionen til færre psykiske helbredssymptomer (i de kommuner, som fokuserer på psykiske helbredssymptomer) og mindre muskelskeletbesvær (i de kommuner, som fokuserer på muskelskeletbesvær)?

      Desuden er det en målsætning for evalueringsprojektet, så vidt datamaterialet tillader det, at lave sensitivitetsanalyser, dvs. at undersøge, om effekten af interventionerne afhænger af karakteristika ved deltagerne (fx køn, alder, social status).

      Med hensyn til procesevaluering skal projekterne være i stand til at besvare følgende spørgsmål:

      - Hvordan blev deltagerne rekrutteret til interventions- og kontrolgruppen?

      - Er inklusionskriterierne veldefinerede og -dokumenterede?

      - Blev rekrutteringsprocessen samt inklusionskriterier ændret i løbet af projektet? Og hvad betød det i så fald for projektets forløb?

      - Hvordan fungerede samarbejdet mellem kommunen og interventionsteamet?

      - Er der en klart defineret og detaljeret interventionsprotokol?

      - Følges interventionsprotokollen i virkeligheden?

      - Er der konkrete skriftlige handlingsplaner for hver deltager i interventionsgruppen?

      - Hvad indeholder handlingsplanerne, og hvad er deres tidsperspektiv?

      - Bliver handlingsplanerne fulgt?

      - Hvordan vurderer interventionsteamet interventionsforløbet?

      - Hvordan vurderer deltagerne interventionsforløbet?

      - Hvordan vurderer de kommunale sagsbehandler interventionsforløbet?

      Selvom de 5 kommunale interventionsprojekter ligner hinanden, har hvert projekt specielle betingelser. Derfor gennemføres 5 separate evalueringer, og der skrives både en evalueringsrapport for hvert projekt og en samlende rapport.

Subjects: subject: Numerical Analysis (math.NA)

description: A new algorithm of the canonical polyadic decomposition (CPD) presented here. It features lower computational complexity and memory usage than the available state of the art implementations. We begin with some examples of CPD applications to real world problems. A short summary of the main contributions in this work follows. In chapter 1 we review classical tensor algebra and geometry, with focus on the CPD. Chapter 2 focuses on tensor compression, which is considered (in this work) to be one of the most important parts of the CPD algorithm. In chapter 3 we talk about the Gauss-Newton method, which is a nonlinear least squares method used to minimize nonlinear functions. Chapter 4 is the longest one of this thesis. In this chapter we introduce the main character of this thesis: Tensor Fox. Basically it is a tensor package which includes a CPD solver. After introducing Tensor Fox we will conduct lots of computational experiments comparing this solver with several others. At the end of this chapter we introduce the Tensor Train decomposition and show how to use it to compute higher order CPDs. We also discuss some important details such as regularization, preconditioning, conditioning, parallelism, etc. In chapter 5 we consider the intersection between tensor decompositions and machine learning. A novel model is introduced, which works as a tensor version of neural networks. Finally, in chapter 6 we reach the final conclusions and introduce our expectations for future developments.
title: The role of the Highland Development Agency: With particular reference to the work of the Congested Districts Board 1897-1912
Creators: name: McCleery, Alison Margaret
Publisher: name: University of Glasgow
Year: 1984
Subjects: subject: Regional planning, area planning & development, Scotland, Highlands Development Agency.

description: This thesis examines the constitution, aims and achievement of the Congested Districts Board (1897-1912) against the wider context of attempts to develop the Scottish Highlands from the late eighteenth century to the twentieth century. The extant records of the Congested Districts Board are used in conjunction with other archive material and with contemporary press articles to assess to what extent the Board was successful in achieving its objectives of developing agriculture and fishing; creating holdings, assisting migration, and enlarging existing holdings; improving communications infrastructure and fostering home industries: and to identify the reasons for the Board's comparative failure. It is contended that the Congested Districts Board was considerably handicapped initially by having a remit wider in scope than its narrow legislative provisions could hope to secure, whether in terms of powers, finance or administrative structure, while at a later stage its confidence was eroded by political uncertainty as to its permanence. In conclusion, it is suggested that the unique contribution of the Board to Highland development lies in its importance as an experiment, demonstrating what is feasible, and in what circumstances, and what is not.

description: We investigate five-dimensional static (non-)extremal black hole solutions in higher derivative Anti-de Sitter gravity theories with neutral scalars non-minimally coupled to gauge fields. We explicitly identify the boundary counterterms to regularize the gravitational action and the stress tensor. We illustrate these results by applying the method of holographic renormalization to computing thermodynamical properties in several concrete examples. We also construct numerical extremal black hole solutions and discuss the attractor mechanism by using the entropy function formalism.

description: A detailed investigation of the magnetic properties of young Sun-like stars can provide valuable information on our Sun's magnetic past and its impact on the early Earth. We determine the properties of the moderately rotating young Sun-like star kappa Ceti's magnetic and activity cycles using 50 years of chromospheric activity data and six epochs of spectropolarimetric observations. The chromospheric activity was determined by measuring the flux in the Ca II H and K lines. A generalised Lomb-Scargle periodogram and a wavelet decomposition were used on the chromospheric activity data to establish the associated periodicities. The vector magnetic field of the star was reconstructed using the technique of Zeeman Doppler imaging on the spectropolarimetric observations. Our period analysis algorithms detect a 3.1 year chromospheric cycle in addition to the star's well-known ~6 year cycle period. Although the two cycle periods have an approximate 1:2 ratio, they exhibit an unusual temporal evolution. Additionally, the spectropolarimetric data analysis shows polarity reversals of the star's large-scale magnetic field, suggesting a ~10 year magnetic or Hale cycle. The unusual evolution of the star's chromospheric cycles and their lack of a direct correlation with the magnetic cycle establishes kappa Ceti as a curious young Sun. Such complex evolution of magnetic activity could be synonymous with moderately active young Suns, which is an evolutionary path that our own Sun could have taken.

Entanglement optimizing mixtures of two-qubit states

description: Entanglement in incoherent mixtures of pure states of two qubits is considered via the concurrence measure. A set of pure states is optimal if the concurrence for any mixture of them is the weighted sum of the concurrences of the generating states. When two or three pure real states are mixed it is shown that 28.5% and 5.12% of the cases respectively, are optimal. Conditions that are obeyed by the pure states generating such optimally entangled mixtures are derived. For four or more pure states it is shown that there are no such sets of real states. The implications of these on superposition of two or more dimerized states is discussed. A corollary of these results also show in how many cases rebit concurrence can be the same as that of qubit concurrence.

Attendance at Indian residential schools in British Columbia, 1890-1920
Creators: name: Redford, James W.
Publisher: name: University of British Columbia
Year: 2010

description: In the late nineteenth century, middle class Canadian reformers tried to use education to change the values and rhythms of working class, immigrant, and Indian children. They used boarding schools, however, only in the case of Indians. Educators expected boarding schools to give them complete control over the environment of their pupils, thus making it possible to rear a generation of culturally and occupationally assimilated Indians. They did not expect their efforts to be blunted or reshaped by existing Indian rhythms. Because Indians were outnumbered, and because their culture was under attack from many directions, historians too have generally assumed that native rhythms had a negligible impact on residential education. Most accounts of the schools portray them as either assisting or victimizing a decimated and essentially helpless minority. This thesis uses Government reports, school records, correspondence, and oral accounts to investigate the way educators and Indians made attendance decisions. It shows that Indians played a vital role in deciding whether children went to residential school; which children went; at what ages they enrolled; how long they stayed; and how much contact they retained with their families and culture while in attendance. It clarifies some of the emotional, economic, and cultural needs which conditioned Indians' attendance decisions. By examining how existing native patterns of life modified a very determined campaign to control and alter Indian society, the thesis hopefully sheds light as well on the gradual, adaptive, and fluid process of "directed" cultural change. Residential schools were not simply an "imposed" social experience, but a mutual and changing relationship shaped by Indians as well as whites.

description: The cryogenic resonant gravitational wave detectors NAUTILUS and EXPLORER, made of an aluminum alloy bar, can detect cosmic ray showers. At temperatures above 1 K, when the material is in the normal conducting state, the measured signals are in good agreement with the values expected based on the cosmic rays data and on the thermo-acoustic model. When NAUTILUS was operated at the temperature of 0.14 K, in superconductive state, large signals produced by cosmic ray interactions, more energetic than expected, were recorded. The NAUTILUS data in this case are in agreement with the measurements done by a dedicated experiment on a particle beam. The biggest recorded event was in EXPLORER and excited the first longitudinal mode to a vibrational energy of about 670 K, corresponding to about 360 TeV absorbed in the bar. Cosmic rays can be an important background in future acoustic detectors of improved sensitivity. At present, they represent a useful tool to verify the gravitational wave antenna performance.
