description: Background: General practitioners (GPs) play a key role in the care of people with dementia (PwD). However, the role of the German Dementia Guideline in primary care remains unclear. The main objective of the present study was to examine the role of guideline-based dementia care in general practices. Methods: A cross-sectional analysis of data obtained from the DemTab study was conducted. Descriptive analyses of sociodemographic and clinical characteristics for GPs (N = 28) and PwD (N = 91) were conducted. Adherence to the German Dementia Guideline of GPs was measured at the level of PwD. Linear Mixed Models were used to analyze the associations between adherence to the German Dementia Guideline and GP factors at individual (age, years of experience as a GP, frequency of utilization of guideline, perceived usefulness of guideline) and structural (type of practice, total number of patients seen by a participating GP, and total number of PwD seen by a participating GP) levels as well as between adherence to the German Dementia Guideline and PwD’s quality of life. Results: Self-reported overall adherence of GPs was on average 71% (SD = 19.4, range: 25–100). Adherence to specific recommendations varied widely (from 19.2 to 95.3%) and the majority of GPs (79.1%) reported the guideline as only partially or somewhat helpful. Further, we found lower adherence to be significantly associated with higher numbers of patients (γ10 = − 5.58, CI = − 10.97, − 0.19, p = .04). No association between adherence to the guideline and PwD’s quality of life was found (γ10 = −.86, CI = − 4.18, 2.47, p = .61). Conclusion: The present study examined the role of adherence to the German Dementia Guideline recommendations in primary care. Overall, GPs reported high levels of adherence. However, major differences across guideline recommendations were found. Findings highlight the importance of guidelines for the provision of care. Dementia guidelines for GPs need to be better tailored and addressed. Further, structural changes such as more time for PwD may contribute to a sustainable change of dementia care in primary care. Trial registration: The DemTab trial was prospectively registered with the ISRCTN registry (Trial registration number: ISRCTN15854413). Registered 01 April 2019.
On the (Non)-Integrability of KdV Hierarchy with Self-consistent Sources

description: Non-holonomic deformations of integrable equations of the KdV hierarchy are studied by using the expansions over the so-called "squared solutions" (squared eigenfunctions). Such deformations are equivalent to perturbed models with external (self-consistent) sources. In this regard, the KdV6 equation is viewed as a special perturbation of KdV equation. Applying expansions over the symplectic basis of squared eigenfunctions, the integrability properties of the KdV hierarchy with generic self-consistent sources are analyzed. This allows one to formulate a set of conditions on the perturbation terms that preserve the integrability. The perturbation corrections to the scattering data and to the corresponding action-angle variables are studied. The analysis shows that although many nontrivial solutions of KdV equations with generic self-consistent sources can be obtained by the Inverse Scattering Transform (IST), there are solutions that, in principle, can not be obtained via IST. Examples are considered showing the complete integrability of KdV6 with perturbations that preserve the eigenvalues time-independent. In another type of examples the soliton solutions of the perturbed equations are presented where the perturbed eigenvalue depends explicitly on time. Such equations, however in general, are not completely integrable.

description: In recent work [1] we uncovered intriguing connections between Otto's characterisation of diffusion as entropic gradient flow [16] on one hand and large-deviation principles describing the microscopic picture (Brownian motion) on the other. In this paper, we sketch this connection, show how it generalises to a wider class of systems, and comment on consequences and implications. Specifically, we connect macroscopic gradient flows with large deviation principles, and point out the potential of a bigger picture emerging: we indicate that in some non- equilibrium situations, entropies and thermodynamic free energies can be derived via large deviation principles. The approach advocated here is different from the established hydrodynamic limit passage but extends a link that is well known in the equilibrium situation.

description: Starting in 2021, the LHCb experiment will switch to a fully software-based trigger system. It is an ongoing challenge to ensure that this system will be able to process events at the required rate of 30 MHz. Two alternative approaches to improve and speed up the particle track reconstruction performed in the first stage of LHCb’s software trigger are presented. An alternative method to the Kalman filter track fit inside the VELO reconstruction is presented. This method uses neural networks to perform the fit and additionally provides an estimation of a track’s momentum based on the track’s scattering. The momentum information enables improved uncertainty estimates for a trajectory’s impact parameter, an important quantity to select tracks from secondary vertices. It is shown that the neural network’s uncertainty prediction enables an equally efficient selection of secondary tracks while reducing the amount of falsely selected prompt tracks by 30%. Additionally, an alternative procedure to reconstruct tracks that traverse the entire LHCb detector is presented. These tracks are LHCb’s main physics objects and their reconstruction previously required a third of the overall processing time of the first trigger stage’s reconstruction sequence. A new algorithm design is proposed, which is shown to yield similar reconstruction efficiencies while providing an over six-fold speedup over the current algorithm. A comparison of trigger configurations, which are able to process data at the rate of 30 MHz, is presented. It shows that a trigger based on the new algorithm yields significantly higher selection efficiencies.

description: There is a diminishing workforce of nurses within British Columbia which affects the ability to provide quality health care, as well as education training and continual support to nurses. The Educator Pathway Project is a pilot project developed using intersectoral methods with the goals of creating an educational model that will allow nurses to acquire and retain skill in various levels of education roles. Four levels of nurse educator roles were identified. For each of the four levels, a competency assessment tool was created, first to guide the curriculum development, and secondly for self-assessment of the nurses participating in the project. The purpose of this study was to determine the validity of each of the four competency assessment tools of the Educator Pathway Project. In this study, competency assessment tools for levels 1 thru 4 were validated using a qualitative comparative methodology. Each tool was validated on two levels — through the 6 core competencies and secondly through the individual indicators of the core competencies. It was found that all core competencies for each of the four levels was validated. Over 70% of the indicators were validated within the literature. Overall it was determined the all four of the competency assessment tools were found to have high validity.

description: The Carnegie-Irvine Galaxy Survey (CGS) is a comprehensive investigation of the physical properties of a complete, representative sample of 605 bright (B_T <= 12.9 mag) galaxies in the southern hemisphere. This contribution describes the isophotal analysis of the broadband (BVRI) optical imaging component of the project. We pay close attention to sky subtraction, which is particularly challenging for some of the large galaxies in our sample. Extensive crosschecks with internal and external data confirm that our calibration and sky subtraction techniques are robust with respect to the quoted measurement uncertainties. We present a uniform catalog of one-dimensional radial profiles of surface brightness and geometric parameters, as well as integrated colors and color gradients. Composite profiles highlight the tremendous diversity of brightness distributions found in disk galaxies and their dependence on Hubble type. A significant fraction of S0 and spiral galaxies exhibit non-exponential profiles in their outer regions. We perform Fourier decomposition of the isophotes to quantify non-axisymmetric deviations in the light distribution. We use the geometric parameters, in conjunction with the amplitude and phase of the m=2 Fourier mode, to identify bars and quantify their size and strength. Spiral arm strengths are characterized using the m=2 Fourier profiles and structure maps. Finally, we utilize the information encoded in the m=1 Fourier profiles to measure disk lopsidedness. The databases assembled here and in Paper I lay the foundation for forthcoming scientific applications of CGS.

description: We model the collapse of a spherically symmetric, constant density, pressureless shell onto a preexisting black hole. Contrary to a recent claim of Liu and Zhang (2009), we show that an observer at infinity never sees any part of the shell cross the event horizon. The entire shell appears to "freeze" outside the black hole. We find that during intermediate stages of the collapse, the change in apparent size of the inner surface is non-monotonic. However, at late times, the apparent sizes of the inner and outer surfaces of the shell both approach 3\sqrt{3}GM/c^2 asymptotically, where M is the combined mass of the initial black hole and the shell.

description: The experimental issue of the search for new particles of unknown mass poses the challenge of exploring a wide interval to look for the usual signatures represented by excess of events above the background. A side effect of such a broad range quest is that the significance calculations valid for signals of known location are no more applicable when such an information is missing. This circumstance is commonly termed in high energy physics applications as the look elsewhere effect. How it concretely manifests in a specific problem of signal search depends upon the particular strategy adopted to unravel the sought-after signal from the underlying background. In this respect an increasingly popular method is the profile likelihood ratio, especially because of its asymptotic behavior dictated by one of the most famous statistic result, the Wilks' theorem. This work is centered on the description of the look elsewhere effect in the framework of the profile likelihood methodology, in particular proposing a conjecture about the distribution of the likelihood ratio under the null hypothesis of absence of the signal over the searched mass interval, a condition which is known to violate the conditions of the Wilks' theorem. Several Monte Carlo tests to support the conjecture are presented, as well.

description: Heterodera glycines or soybean cyst nematode (SCN) is one of the most yield-limiting soybean plant pathogens. The HG (Heterodera glycines) type test is a greenhouse test to determine the virulence of SCN populations to seven soybean “indicator” lines. Since there has not been a survey of SCN virulence phenotypes in Indiana in over a decade, a total of 124 samples were collected, and all tested positive for SCN. Of 42 selected populations for the HG type test, 88% were virulent to the soybean breeding line PI 88788, from which most SCN-resistant cultivars derive their resistance. All populations were virulent to at least one indicator line, including PI 548402 (‘Peking’), which pose problems for the future of soybean breeding for SCN. Meloidogyne spp. or root-knot nematodes (RKNs) are extremely damaging to agriculture, especially to specialty crops. RKN species are attracted by plant root exudates. The gene expression of M. javanica second-stage juveniles was determined after exposure to tomato root exudates, and the differentially expressed genes were analyzed.

description: In this thesis, searches for physics effects beyond the Standard Model are performed by studying purely leptonic and lepton-flavour violating B-meson decays with the LHCb experiment. Advanced statistical tools to interpret nulltests are implemented and used in the analysis of the very rare decays discussed in this thesis. A search for lepton-flavour violating B+→K+µ±e∓ decays is performed based on the LHCb Run 1 sample as the first analysis of these transitions with LHCb data. Upper limits on their branching fractions are set below 10^{-8}, which improves previous limits by more than an order of magnitude. Similarly, B0(s)→e+e- decays have never before been studied with the LHCb experiment. The upper limits on their branching fractions determined in this thesis with Run 1 and part of Run 2 data improve previous limits by a factor of 30, reaching a sensitivity of O(10^{-8}). With this improvement the limits become sensitive to scenarios of new physics effects. In a third analysis, the B0(s)→µ+µ- decays are studied with the full LHCb Run 1 and Run 2 data sample. The analysis is currently being reviewed by the collaboration. Its precision is expected to be similar to that of the combination of previous results of the LHC experiments obtained on a partial data set. The results obtained in this thesis impose strong constraints on popular scenarios of new physics effects.

Entangled photon pairs of 810 nm wavelength generated by a Sagnac interferometer source were coupled into standard telecom single mode fibers. The fibers were either dark or carrying a standardized 1550 nm ethernet signals (1000BASE-ZX) with a nominal speed of 1 GBps from regular media converter devices, without any requirements on the optical power or spectrum transmitted. Our system demonstrates a QKD network covering 6 km in distance with a central service provider for classical and quantum data.

description: We present EzGal, a flexible python program designed to easily generate observable parameters (magnitudes, colors, mass-to-light ratios) for any stellar population synthesis (SPS) model. As has been demonstrated by various authors, the choice of input SPS models can be a significant source of systematic uncertainty. A key strength of EzGal is that it enables simple, direct comparison of different models sets. EzGal is also capable of generating composite stellar population models (CSPs) and can interpolate between metallicities for a given model set. We have created a web interface to run EzGal and generate observables for a variety of star formation histories and model sets. We make many commonly used SPS models available from this interface; the BC03 models, an updated version of these models, the Maraston models, the BaSTI models, and finally the FSPS models. We use EzGal to compare magnitude predictions for the model sets as a function of wavelength, age, metallicity, and star formation history. We recover the well-known result that the models agree best in the optical for old, solar metallicity models, with differences at the ~0.1 magnitude level. The most problematic regime for SPS modeling is for young ages (<2 Gyrs) and long wavelengths (lambda >7500 Angstroms) where scatter between models can vary from 0.3 mags (Sloan i) to 0.7 mags (Ks). We find that these differences are best understood as general uncertainties in SPS modeling. Finally we explore a more physically motivated example by generating CSPs with a star formation history matching the global star formation history of the universe. We demonstrate that the wavelength and age dependence of SPS model uncertainty translates into a redshift dependent model uncertainty, highlighting the importance of a quantitative understanding of model differences when comparing observations to models as a function of redshift.

description: We theoretically demonstrate the concept of metadamping in dissipative metamaterials. We consider an infinite mass-spring chain with repeated local resonators and a statically equivalent periodic chain whose wave propagation characteristics are based on Bragg scattering. For each system we introduce identical viscous damping (dashpot) elements and compare the damping ratio associated with all Bloch modes. We find that the locally resonant metamaterial exhibits higher dissipation overall which indicates a damping emergence phenomena due to the presence of local resonance. We conclude our investigation by quantifying the degree of emergent damping as a function of the long-wave speed of sound in the medium or the static stiffness.

Multi-component scalar dark matter from a spherical compactification
Creators: name: Winslow, Peter Thomas
Publisher: name: University of British Columbia
Year: 2010

description: Current cosmological measurements of the various components of mass in the Universe indicate that a significant contribution to the total mass density is due to a previously undiscovered type of matter that must be both non-luminous and non-baryonic in nature, aptly named dark matter. The standard model of particle physics, while describing the results of collider experiments with unprecedented precision, does not include a suitable dark matter candidate. All of this is clear and strong evidence for the existence of new physics beyond both the standard models of particle physics and cosmology. One of the recent main areas of interest to physicists exploring beyond standard model physics is theories which incorporate extra dimensions. All of these theories postulate that the 3+1 spacetime that we experience exists as a localized subspace embedded within a larger (3+n)+1 spacetime. Among the many interesting motivations for exploring the phenomenology of extra dimensional models is the existence of a viable dark matter candidate, which has been found to arise somewhat naturally within the context of certain models. In the present work we consider a six dimensional model in which the two extra spatial dimensions are compactified onto a spherical geometry. An imposed parity and a subset of the spherical symmetry of the extra dimensions is then exploited to stabilize a number of massive four dimensional Kaluza Klein excitations, thereby leading to a self interacting multi-component theory of dark matter. The Boltzmann equations describing this system are then solved in order to simultaneously determine the relic densities of the stable dark matter particles. In the following thesis, we will describe this theory in detail along with its motivations, consequences, and compatibility with current observational data.

description: A transfer matrix method is presented for solving the scattering problem for the quasi one-dimensional massless Dirac equation applied to graphene in the presence of an arbitrary inhomogeneous electric and perpendicular magnetic field. It is shown that parabolic cylindrical functions, which have previously been used in literature, become inaccurate at high incident energies and low magnetic fields. A series expansion technique is presented to circumvent this problem. An alternate method using asymptotic expressions is also discussed and the relative merits of the two methods are compared.

description: The phenomenon of electron paramagnetic resonance is described microscopically using the rotating.codrdinate methodand macroscopically using the Bloch formalism. Two major nonradiative physical processes, the spin-lattice and spin-spin interactions, whereby a paramagnetic system can loose energy to its environment are briefly discussed. A qualitative description of the crystal-field theory is given. The spin-C Hamiltonian formalism developed by Abragam and Pryce (1951) for interpreting paramagnetic resonance experimental results is described. The conventional (Bleaney, etal., 1951) and generalized spin-Hamiltonian (Grant and Strandberg, 1964) for gadolinium, in lanthanum ethyl sulphate, arederived. The proposed mechanisms for interpreting:the splittingof the ground 8S state of Gd 3+ are reviewed. The EPR spectra of 0.1 per cent Gd 3 as a paramagnetic impurity in lanthanum ethyl' -sulphate were measured at'290°K using 5,10 and 35GHz. spectrometers which, are described. ,The parameters in the conventional:, and genèralizedspin-,Hamiltohian for,' Gin Ianthanum.ethyl, sü1hate were determined at directions parallel and perpendicuThr to lhe cry.sta1 :y 'metry axis using the 5, lQ and35GHz EPR spectra of AM = ± 1 transitions.

description: Since October 1, 1991, the GEOMAR Marine Research Center Kiel, the Institute of Baltic Sea Research Warnemuende and the geological department of the University of Greifswald perform investigations of sedimentation processes of in the Mid Atlantic Ridge (MAR), with special emphasis on the central part of the Reykjanes Ridge. This joint research project is supported by the "Federal Minister for Research and Technology". It is closely connected to the international Mid Ocean Ridge - research programs "Ridge" - USA, "Bridge" - UK and the new European "InterRidge" activity.

At the beginning of 1992 the possibility came up of using the research vessel "Sonne" for marine geological and geophysical investigations within the framework of the MAR project. RV "Sonne", which is one of the most advanced German research vessels, offers good working conditions especially for the investigation of the unregular sea bottom structures and the small sediment ponds of the MOR regions.

The research cruise "Sonne - 82" (SO82) was planned to start in Balboa (Panama) on September 29, and to finish in Bremerhaven (Germany) on October 31, 1992. Because of the long transfer from Balboa to the area of interest the cruise was divided in two parts.

The task of the first part (S082A - transfer from Balboa, Panama, September, 29 to Reykjavik, Iceland, October, 16) was to carry out a methodic - geophysical program with the aim to adapt advanced acoustic subbottom profiling systems of very high resolution to the acoustically difficult conditions in the MAR area. In order to solve this task a new joint research project "Sedimentation in the Reykjanes ridge: sediment echosounding" was established under the leadership of the University of Rostock (Prof. Wendt). This program is supported by the "Federal Minister for Research and Technology". As a result of this program the advanced acoustic systems required for the complicated tasks to be solved during part SO82B would become available. Furthermore, using the multibeam echosounder Hydrosweep, the central part of the Mid Atlantic Ridge (MAR) between 53°N and 61°N was planned to be mapped in order to achieve information on its tectonic history and subdivision in area of different developments.

The second part (S082B) was to be focused on the investigation of sedimentation processes and its spatial and temporal variability in the central part of the Reykjanes Ridge near 59°N. The methods used include acoustic profiling, sediment sampling and complex (sedimentological, geochemical, physical, biological) investigations of recovered samples. The results will be used to build a model of the genesis of the distributive province "Reykjanes Ridge".

description: Endverbraucher melden nur sehr selten nicht legitime E-Mails. Dabei ist die Bereitschaft solche E-Mails zu melden durchaus vorhanden, wie eine im Rahmen dieser Arbeit durchgeführte Umfrage zeigt. Der Grund für die niedrigen Reportraten ist die Komplexität des Reportverfahrens. Daher wurde ein neuer vereinfachter Prozess zum Melden von nicht legitimen E-Mails definiert. Dieser erlaubt es verdächtige E-Mails unklassifiziert zu melden. Während dies bisher nur entweder als Spam oder als Phishing E-Mail möglich ist. Die zugehörigen Reports werden automatisch im X-ARF Format erzeugt. Da solche automatisch erzeugten Meldungen sensible Informationen enthalten können wird der Endverbraucher befähigt, diese Reports zu anonymisieren. Als Beweis der Umsetzbarkeit des neuen Prozesses wurde in dieser Arbeit ein Plug-In für den Thunderbird E-Mail-client entwickelt. Das verwendete X-ARF Format erlaubte eine einfache Automatisierung der Verarbeitung der Reports. Als Nachweis der Machbarkeit wurde ein Report Aggregator entwickelt, der in der Lage ist Reports zu sammeln und eine fundamentale Validierung des Formats durchzuführen.
description: End user e-mail abuse reporting rates are very low, however a survey conducted in this thesis revealed that the desire to report abusive e-mails exists. The reason why the report rates are so low is that the process to report abusive e-mails is very time consuming and complex. Therefore, a new process for e-mail abuse reporting is defined. In this new reporting process, end users are able to report suspicious e-mails instead of spam or phishing e-mails. Furthermore, abuse reports are automatically generated in the X-ARF format. But since automatically generated reports can contain sensitive information, the end user has to have the option of anonymizing reports before sending them. As a proof of concept for the feasibility of this reporting process a Thunderbird plugin was developed. The X-ARF format of the report enables a very simple implementation of automation for the handling of these reports. Therefore, as another conceptual proof, a report aggregator was developed. Which is able, to perform basic validation functionality.

description: In this work we establish trace Hardy and trace Hardy-Sobolev-Maz'ya inequalities with best Hardy constants, for domains satisfying suitable geometric assumptions such as mean convexity or convexity. We then use them to produce fractional Hardy-Sobolev-Maz'ya inequalities with best Hardy constants for various fractional Laplacians. In the case where the domain is the half space our results cover the full range of the exponent $s \in (0,1)$ of the fractional Laplacians. We answer in particular an open problem raised by Frank and Seiringer \cite{FS}.

description: Doping of semiconductor is necessary for various device applications. Exploiting chemistry at its reactive edges was shown to be an effective way to dope an atomically thin graphene nanoribbon (GNR) for realizing new devices in recent experiments. The carrier mobility limited by edge doping is studied as a function of the GNR width, doping density, and carrier density by using ab initio density functional and parameterized tight binding simulations combined with the non-equilibrium Green's function formalism for quantum transport. The results indicate that for GNRs wider than about 4nm, the mobility scales approximately linearly with the GNR width, inversely proportional to the edge doping concentration and decreases for an increasing carrier density. For narrower GNRs, dependence of the mobility on the GNR width and carrier density can be qualitatively different.

description: This study investigates the lived experiences of Irish museum and gallery staff, and their professional relationship with visitor research which is a new demand on these museums and galleries. The study uncovers staff attitudes to, and perceptions of, visitor research. It identifies potential barriers to the integration of research processes and the impact this might have on the evidence base produced. It makes a number of suggestions as to how visitor research could be reimagined within the Irish museum and gallery. Successful integration of visitor research in these institutions is not a simple matter of advocating for it through policy, nor is it a matter of providing tools for staff to utilise. To truly embed these practices in the working lives of museum/gallery staff a holistic intervention is needed; one that is better aligned with current practice and culture. Additionally, for sustained and meaningful delivery of visitor research, a real investment in the human resources in these institutions is required. Such an intervention could move visitor research from being a process that is often hampered by work practices, labour structures and organisational culture, to being an inclusive process that feeds in and out of all these aspects of the organisation to build stronger, better informed institutions.
Dynamics of Gaussian discord between two oscillators interacting with a common environment

description: We analyze the evolution of the Gaussian discord between two resonant harmonic oscillators coupled to a common environment. For this, we use the same tools we applied before to fully characterize the evolution of the entanglement in this system [ Phys. Rev. Lett. 100 220401 (2008)]. The asymptotic value of Gaussian discord is obtained as a function of parameters characterizing the environment (temperature, couplings, etc.) and the initial state of the system (initial squeezing, initial purity, etc.) The type of Gaussian measurement optimizing the extraction of information between the oscillators is fully characterized by means of a phase diagram. Such a diagram (with phases corresponding to homodyne or heterodyne measurements) has similar topology to the one describing dynamical phases for the entanglement. We present evidence pointing to the fact that Gaussian discord is not always a good approximation of true discord as the asymptotic value of the former is shown to be a nondecreasing function of temperature (in the high-temperature regime), reaching an asymptotic value of log(2) for a pure initial state (and lower values for mixed initial states).
