description: Ground-based high-resolution transmission spectroscopy has emerged as a promising technique for detecting chemicals in transiting exoplanetary atmospheres. Despite chemical inferences in several exoplanets and previous robustness studies, a robust and consistent detrending method to remove telluric and stellar features from transmission spectra has yet to be agreed upon. In this work we investigate the robustness of metrics used to optimise PCA-based detrending for high-resolution transmission spectra of exoplanets in the near-infrared. As a case study, we consider observations of the hot Jupiter HD 189733 b obtained using the CARMENES spectrograph on the 3.5 m CAHA telescope. We confirm that optimising the detrending parameters to maximise the S/N of a cross-correlation signal in the presence of noise has the potential to bias the detection significance at the planetary velocity of optimisation. However, we find that optimisation using the difference between a signal-injected cross-correlation function and the direct cross-correlation function (CCF) is more robust against over-optimisation of noise and spurious signals. We additionally examine the robustness of weighting the contribution of each order to the final CCF, and of S/N calculations. Using a prescribed robust methodology, we confirm H2O in the atmosphere of HD 189733 b (S/N = 6.1). We then investigate two further case studies, of exoplanets HD 209458 b and WASP-76 b, confirming OH in the atmosphere of WASP-76 b (S/N = 4.7), and demonstrating how non-robust methods may induce false positive or inflated detections. Our findings pave the way towards a robust framework for homogeneous characterisation of exoplanetary atmospheres using high-resolution transmission spectroscopy in the near-infrared.

Proper orthogonal decomposition
phase contrast magnetic resonance imaging

description: Abstract:

Proper orthogonal decomposition (POD) is applied to reconstruct noisy data of

blood flow in a carotid artery. In order to show the effectiveness of the method,

we applied this method on data obtained by computational fluid dynamics (CFD).

The geometry used for this study was generated based on patient specific phase

contrast magnetic resonance imaging (PC-MRI) technique. A Gaussian noise was

added to a set of CFD data with slightly different boundary condition (BC) than

BCs were used to generate the POD, in order to take into account the uncertainty

of readying boundary condition from PC-MRI. The results show good agreement

with the original CFD data. This method can potentially be developed as a service

for PC-MRI providers to generate noise free PCI-MRI images and ultimately can

help with further patient specific studies which are based on in vivo velocity

profiles. Pressure difference calculations and wall shear stress (WSS) are just two

out of many potential outputs of this study.

description: We revisit the calculation of the electron, neutron, and proton electric dipole moments (EDMs) in the constrained minimal supersymmetric standard model (CMSSM). The relatively large mass of the Higgs boson, $m_H \simeq 125$ GeV coupled with the (as yet) lack of discovery of any supersymmetric particle at the LHC, has pushed the supersymmetry breaking scale to several TeV or higher. Though one might expect this decoupling to have relaxed completely any bounds on the two CP violating phases in the CMSSM ($θ_μ$ and $θ_A$), the impressive experimental improvements in the limits on the EDMs (particularly the electron EDM) still allow us to set constraints of order $(0.01 - 0.1)π$ on $θ_A$ and $(0.001 - 0.1)π$ on $θ_μ$. We also discuss the impact of future improvements in the experimental limits on supersymmetric models.

description: Healthcare-associated foodborne outbreaks (HAI-FBO) can cause severe morbidity and mortality, especially to highly vulnerable populations and lead to disruption of services. In Germany, only 45% of monitored healthcare institutions were aware of existing recommendations to prevent foodborne infections. There are indications that HAI-FBOs are underestimated. We performed a literature review on HAI-FBO in OECD countries, and analysed surveillance data in Germany, to describe the HAI-FBO epidemiology. HAI-FBO was defined as two or more cases of a disease involving a likely foodborne transmission within a healthcare setting. We searched PubMed, the Nosocomial Outbreak Database, and hand-searched additional references for HAI-FBOs with outbreak onset between 2001 and 2018 occurring in OECD countries. We extracted number of cases, deaths, associated pathogens, suspected food vehicles and contributing risk factors. We searched the German surveillance system to identify HAI-FBOs between 2012 and 2017. The literature search retrieved 49 HAI-FBOs, mainly caused by Listeria monocytogenes (15/49), Salmonella (17/49) and norovirus (8/49). The HAI-FBOs occurred in 17 OECD countries, primarily in the US, the UK and Germany (27/49). Number of fatalities was highest in L. monocytogenes outbreaks (52 deaths/128 cases). In the German surveillance system, we identified 16 HAI-FBO (total cases, n=484), caused by norovirus, Salmonella, Campylobacter and L. monocytogenes. Associated food vehicles included mixed foods, salads, vegetables, fruits and foods of animal origin. Unprocessed contaminated ingredients, inadequate heat treatment and risky foods were reported as contributing risk factors. A variety of food vehicles including risk foods (e.g. raw sausage) were associated with HAI-FBO. We assumed that the low number of published HAI-FBO was due to publication bias and the public health importance may currently be underestimated. Identification of HAI-FBOs should be improved, existing food safety guidelines strictly implemented and harmonized between clinical hygiene and food safety authorities.

description: The amplitude and morphology of light curves of solar-like stars change substantially with increasing rotation rate: brightness variations get amplified and become more regular, which has so far not been explained. We develop a modelling approach for calculating brightness variations of stars with various rotation rates and use it to explain observed trends in stellar photometric variability. We combine numerical simulations of magnetic Flux Emergence And Transport (FEAT) with a model for stellar brightness variability to calculate synthetic light curves of stars as observed by the Kepler telescope. We compute the distribution of magnetic flux on the stellar surface for various rotation rates and degrees of active-region nesting (i.e., the tendency of active regions to emerge in the vicinity of recently emerged ones). Using the resulting maps of the magnetic flux, we compute the rotational variability of our simulated stellar light curves as a function of rotation rate and nesting of magnetic features and compare our calculations to Kepler observations. We show that both rotation rate and degree of nesting have a strong impact on the amplitude and morphology of stellar light curves. In order to explain the variability of the bulk of \K{} targets with known rotation rates, we need to increase the degree of nesting to values much larger than on the Sun. The suggested increase of nesting with the rotation rate can provide clues to the flux emergence process for high levels of stellar activity.

description: We discuss fast frictionless cooling techniques in the framework of sympathetic cooling of cold atomic mixtures. It is argued that optimal cooling of an atomic species - in which the deepest quantum degeneracy regime is achieved - may be obtained by means of sympathetic cooling with another species whose trapping frequency is dynamically changed to maintain constancy of the Lewis-Riesenfeld adiabatic invariant. Advantages and limitations of this cooling strategy are discussed, with particular regard to the possibility of cooling Fermi gases to a deeper degenerate regime.

The use of large amounts of liquid Argon is foreseen in different projects, like the DarkSide-20k experiment, intended to look for Weakly Interacting Massive Particles at the Laboratori Nazionali del Gran Sasso. Here, results from the study of the cosmogenic activation of Argon carried out in the context of DarkSide-20k are presented. The induced activity of several isotopes, including 39Ar, and the expected counting rates in the detector have been deduced, considering exposure conditions as realistic as possible.

description: Highly oriented pyrolytic graphite (HoPG) may be the only known monatomic crystal with the ability to host naturally formed moire patterns on its cleaved surfaces, which are coherent over micrometer scales and with discrete sets of twist angles of fixed periodicity. Such an aspect is in marked contrast to twisted bilayer graphene (TBG) and other multilayered systems, where the long range coherence of the moire is not easily maintained due to twist angle disorder. We investigate the electronic and mechanical response of coherent graphite moire patterns through inducing external strain from STM tip-induced deformation. Consequently, unique anisotropic mechanical characteristics are revealed. For example, a lateral widening of one-dimensional (1D) domain walls (DWs) bridging Bernal (ABA) and rhombohedral (ABC) stacking domains (A, B and C refer to the atomic layer positioning), was indicated. Further, in situ tunneling spectroscopy as a function of the deformation indicated a tendency towards increased electrical conductance, which may be associated with a higher density of electronic states, and the consequent flattening of the electronic energy band dispersion. Such features were probed across the DWs, with implications for strain-induced electronic modulation of the moire characteristics.

description: Asymptotically warped AdS spacetimes in topologically massive gravity with negative cosmological constant are considered in the case of spacelike stretched warping, where black holes have been shown to exist. We provide a set of asymptotic conditions that accommodate solutions in which the local degree of freedom (the "massive graviton") is switched on. An exact solution with this property is explicitly exhibited and possesses a slower fall-off than the warped AdS black hole. The boundary conditions are invariant under the semidirect product of the Virasoro algebra with a u(1) current algebra. We show that the canonical generators are integrable and finite. When the graviton is not excited, our analysis is compared and contrasted with earlier results obtained through the covariant approach to conserved charges. In particular, we find agreement with the conserved charges of the warped AdS black holes as well as with the central charges in the algebra.

Mothers' experiences : participating in the feedback conference of their chld's psychoeducational assessment
Creators: name: Merkel, Carla
Publisher: name: University of British Columbia
Year: 2010

description: A comprehensive psychoeducational assessment for a child who is having learning or behavioural difficulties is a significant event for parents. It helps them understand their child’s cognitive and learning needs, and support the ongoing development of their children by determining the educational support given at home, and additional services that need to be provided. How parents view the overall assessment and the psychologist’s recommendations can have a great impact on what decisions they make for the child following the assessment; it forms the basis for how they approach their child’s difficulties and meet his/her needs. However, there are few studies that examine parents’ experience with this assessment process. The purpose of this study was to understand mothers’ experiences with participating in the feedback conference for their child’s psychoeducational assessment and to explore the experiences that influenced their ability to follow through with the recommendations made by the psychologist. Interpretative Phenomenological Analysis methodology was used to analyze the interview data from eight mothers of elementary school-age children who had a psychoeducational assessment within the past year. The emphasis of this study was on the meaning of this experience for mothers. Three broad themes and 11 subthemes emerged from the analysis of mothers’ experiences with the feedback conference, which included: Experiences of Finding Out, Emotional Experiences, and Experiences of Satisfaction. With respect to follow through with recommendations, eight subthemes were identified, which were grouped into three broad themes: Experiences Facilitating Follow Through, Experiences Inhibiting Follow Through, and Experiences Facilitating or Inhibiting Follow Through. These themes are presented and discussed in relation to the existing literature. Implications of the study, strengths and limitations and suggestions for future research are also addressed.

description: In this paper, we presented the mass spectra of the doubly heavy $Ω$ baryons containing one light (strange) quark and two heavy (charm and bottom) quarks. Our predicted masses can be consider to determine the $J^p$ value for the resonances detected by experimental facilities in future. The masses of ground excited states (1S-6S, 1P-3P, 1D-2D, 1F-2F) are calculated for all possible $J^p$ values, using the Hypercentral Constituent Quark Model (hCQM), by employing screened potential as confining potential with color-Coloumb potential. Regge trajectories are also plotted in $(J, M^2)$ plane for natural and unnatural parities. Doubly heavy Omega states are not declared yet by any experimental facility. We compared our results to the predictions gained from other theoretical approaches, and we found that our predictions are quite close to those of them. Other properties such as magnetic moment (for spin state $\frac{1}{2}$ and $\frac{3}{2}$) and radiative decay width are calculated using the enuerated masses.

description: We present an analysis of the globular cluster NGC 2419, using a polytropic model in Modified Newtonian Dynamics (MOND) to reproduce recently published high quality data of the structure and kinematics of the system. We show that a specific MOND polytropic model of NGC 2419 suggested by a previous study can be completely ruled out by the data. Furthermore, the highest likelihood fit polytrope in MOND is a substantially worse model (by a factor of approximately 5000) than a Newtonian Michie model studied in an earlier contribution by Ibata et al. (2011). We conclude that the structure and dynamics of NGC 2419 favor Newtonian dynamics and do indeed challenge the MOND theory.

A Functional, Comprehensive And Extensible Multi-Platform Querying And Transformation Approach

description: This thesis is about a new model querying and transformation approach called FunnyQT which is realized as a set of APIs and embedded domain-specific languages (DSLs) in the JVM-based functional Lisp-dialect Clojure.

Founded on a powerful model management API, FunnyQT provides querying services such as comprehensions, quantified expressions, regular path expressions, logic-based, relational model querying, and pattern matching. On the transformation side, it supports the definition of unidirectional model-to-model transformations, of inplace transformations, it supports defining bidirectional transformations, and it supports a new kind of co-evolution transformations that allow for evolving a model together with its metamodel simultaneously.

Several properties make FunnyQT unique. Foremost, it is just a Clojure library, thus, FunnyQT queries and transformations are Clojure programs. However, most higher-level services are provided as task-oriented embedded DSLs which use Clojure‘s powerful macro-system to support the user with tailor-made language constructs important for the task at hand.

Since queries and transformations are just Clojure programs, they may use any Clojure or Java library for their own purpose, e.g., they may use some templating library for defining model-to-text transformations. Conversely, like every Clojure program, FunnyQT queries and transformations compile to normal JVM byte-code and can easily be called from other JVM languages.

Furthermore, FunnyQT is platform-independent and designed with extensibility in mind. By default, it supports the Eclipse Modeling Framework and JGraLab, and support for other modeling frameworks can be added with minimal effort and without having to modify the respective framework‘s classes or FunnyQT itself.

Lastly, because FunnyQT is embedded in a functional language, it has a functional emphasis itself. Every query and every transformation compiles to a function which can be passed around, given to higher-order functions, or be parametrized with other functions.

description: This paper studies the effect of reference frame selection in sensor-to-sensor extrinsic calibration when formulated as a motion-based hand-eye calibration problem. Different reference selection options are tested under varying noise conditions in simulation, and the findings are validated with real data from the KITTI dataset. We propose two nonlinear cost functions for optimization and compare them with four state-of-the-art methods. One of the proposed cost functions incorporates outlier rejection to improve calibration performance and was shown to significantly improve performance in the presence of outliers, and either match or outperform the other algorithms in other noise conditions. However, the performance gain from reference frame selection was deemed larger than that from algorithm selection. In addition, we show that with realistic noise, the reference frame selection method commonly used in literature is inferior to other tested options, and that relative error metrics are not reliable for telling which method achieves best calibration performance.

A robust method for reliability updating with equality information using sequential adaptive importance sampling

description: Reliability updating refers to a problem that integrates Bayesian updating technique with structural reliability analysis and cannot be directly solved by structural reliability methods (SRMs) when it involves equality information. The state-of-the-art approaches transform equality information into inequality information by introducing an auxiliary standard normal parameter. These methods, however, encounter the loss of computational efficiency due to the difficulty in finding the maximum of the likelihood function, the large coefficient of variation (COV) associated with the posterior failure probability and the inapplicability to dynamic updating problems where new information is constantly available. To overcome these limitations, this paper proposes an innovative method called RU-SAIS (reliability updating using sequential adaptive importance sampling), which combines elements of sequential importance sampling and K-means clustering to construct a series of important sampling densities (ISDs) using Gaussian mixture. The last ISD of the sequence is further adaptively modified through application of the cross entropy method. The performance of RU-SAIS is demonstrated by three examples. Results show that RU-SAIS achieves a more accurate and robust estimator of the posterior failure probability than the existing methods such as subset simulation.

We explore the parameter space for different accretion timescales and feedback eficiencies, and we find that as planet luminosity increases, the mass of the circumplanetary region decreases, regulating the accretion rate.

description: The ADM energy for asymptotically flat spacetimes or its generalizations to asymptotically non-flat spacetimes measure the energy content of a stationary spacetime, such as a single black hole. Such a stationary energy is given as a geometric invariant of the spatial hypersurface of the spacetime and is expressed as an integral on the boundary of the hypersurface. For non-stationary spacetimes, there is a refinement of the ADM energy, the so-called Dain's invariant that measures the non-stationary part, the gravitational radiation component, of the total energy. Dain's invariant uses the metric and the extrinsic curvature of the spatial hypersurface together with the so-called approximate Killing initial data and vanishes for stationary spacetimes. In our earlier work [Phys.Rev.D 101 (2020)2, 024035], we gave a reformulation of the non-stationary energy for vacuum spacetimes in the Hamiltonian form of General Relativity written succinctly in the Fischer-Marsden form. That formulation is relevant for merging black holes or other compact sources. Here we extend this formulation to non-vacuum spacetimes with a perfect fluid source. This is expected to be relevant for spacetimes that have a compact star, say a neutron star colliding with a black hole or another non-vacuum object.

description: We present observations from X-ray to mid-infrared wavelengths of the most energetic non-quasar transient ever observed, AT2021lwx. Our data show a single optical brightening by a factor $>100$ to a luminosity of $7\times10^{45}$ erg s$^{-1}$, and a total radiated energy of $1.5\times10^{53}$ erg, both greater than any known optical transient. The decline is smooth and exponential and the ultra-violet - optical spectral energy distribution resembles a black body with temperature $1.2\times10^4$ K. Tentative X-ray detections indicate a secondary mode of emission, while a delayed mid-infrared flare points to the presence of dust surrounding the transient. The spectra are similar to recently discovered optical flares in known active galactic nuclei but lack some characteristic features. The lack of emission for the previous seven years is inconsistent with the short-term, stochastic variability observed in quasars, while the extreme luminosity and long timescale of the transient disfavour the disruption of a single solar-mass star. The luminosity could be generated by the disruption of a much more massive star, but the likelihood of such an event occurring is small. A plausible scenario is the accretion of a giant molecular cloud by a dormant black hole of $10^8 - 10^9$ solar masses. AT2021lwx thus represents an extreme extension of the known scenarios of black hole accretion.

description: For a reliable prediction of the NMSSM Higgs boson signatures at present and future high-energy colliders and a proper distinction of the NMSSM and MSSM Higgs sector the precise knowledge of the Higgs boson masses including higher-order corrections is indispensable. In this paper, the one-loop corrections to the neutral NMSSM Higgs boson masses and mixings are calculated in three different renormalisation schemes. In addition to the $\bar{DR}$ renormalisation scheme, existing in the literature, two other schemes are adopted. Furthermore, the dependence on the value of the top quark mass is investigated. The resulting Higgs mass corrections have been compared and the residual theory error due to missing higher-order corrections can be estimated to be of the order of 10%.

Exploring how level of training, inclusion, and problem behaviour affect student-teacher relationships for students with autism spectrum disorders
Creators: name: Brown, Jacqueline A
Publisher: name: University of British Columbia
Year: 2010

description: This study examined the quality of relationships between students with Autism Spectrum Disorders (ASD) and their classroom teachers and Special Educational Assistants (SEAs). Specifically, it examined how level of inclusion, problem behaviour, adaptive behaviour, and amount of training in ASD affects the student-teacher and student-SEA relationship. Participants were 15 students with ASD receiving inclusive education in grades K through three, their classroom teachers, and SEAs. Teachers and SEAs completed rating scales assessing problem behaviour, adaptive behaviour, and the quality of student-teacher relationships. Analyses consisted of Pearson correlations and multiple regressions to identify which alterable variables can be targeted to improve the relationships between students with ASD and their teachers. Results showed that the level of problem behaviour and percent of student inclusion were significantly related to the student-teacher relationship, but not the student-SEA relationship. These results are discussed with regard to previous and future research, limitations, and implications for supporting students with ASD.

description: In this work, I consider an inflation model with a quadratic potential and a negative cosmological constant. An analytical solution of the equation of motion for the inflaton field is found without slow-roll approximation. The result is that the inflation field is rolling at a constant speed. The prediction for cosmological perturbation is calculated.

Publisher: name: Zenodo
Year: 2016

description: The Flying Saucer is an edge-on protoplanetary disk in the outskirts of the

rho Ophiucus core. ALMA revealed that the dust disk is absorbing the CO emission of background clouds, providing a first direct measurement of the temperature of dust grains dominating the mm emission. These grains are much colder than expected, with only 5 to 7 K at 100 au, challenging current disk models.

description: Rat-borne Seoul hantaviruses are only just being recognized globally as important human pathogens, even though they have been studied and isolated on 4 different continents (Asia, Europe, the Americas, and Africa) since the early 1980s. Recent reports from Europe and the USA described Seoul hantavirus infection in pet rats and their breeders or owners, suggesting the potential emergence of a “new” public health problem. Wild and laboratory rat-induced Seoul hantavirus infections have, however, been described since the early eighties, due to the omnipresence of the rodent reservoir, the brown rat Rattus norvegicus. Recent studies showed no fundamental differences between pathogenicity and phylogeny of pet rat-Seoul hantaviruses and their formerly described wild or laboratory rat counterparts. The paucity of diagnosed Seoul virus-induced disease in the West is in striking contrast to the thousands of cases recorded since the 1980s in the Far-East, particularly in China. This review of four continents (Asia, Europe, America, and Africa) puts this “emerging infection” in historic perspective, concluding there is an urgent need for greater medical awareness of Seoul virus-induced human pathology in many parts of the world. Given the mostly milder and atypical clinical presentation, sometimes with preserved normal kidney function, the importance of simple urine examination is stressed, since initial, massive but transient proteinuria and microhematuria are rarely lacking. With increasingly sophisticated technology and enhanced clinical awareness, many specific hantaviruses are now recognized; however, SEOV remains the globally most widely distributed hantavirus.

description: We report the near-field ablation of material from cellulose acetate coverslips in water and my- oblast cell samples in growth media, with a spot size as small as 1.5 μm under 3 μm wavelength radiation. The power dependence of the ablation process has been studied and comparisons have been made to models of photomechanical and plasma-induced ablation. The ablation mechanism is mainly dependent on the acoustic relaxation time and optical properties of the materials. We find that for all near-field experiments, the ablation thresholds are very high, pointing to plasma-induced ablation as the dominant mechanism.

description: Virtual Humans (VHs) were first developed more than 50 years ago and have undergone significant advancements since then. In the past, creating and animating VHs was a complex task. However, contemporary commercial and freely available technology now empowers users, programmers, and designers to create and animate VHs with relative ease. These technologies have even reached a point where they can replicate the authentic characteristics and behaviors of real actors, resulting in VHs that are visually convincing and behaviorally lifelike. This paper explores three closely related research areas in the context of virtual humans and discusses the far-reaching implications of highly realistic characters within these domains.

description: The MALTA CMOS monolithic silicon pixel sensors has been developed in the Tower 180 nm CMOS imaging process. It includes an asynchronous readout scheme and complies with the ATLAS inner tracker requirements for the HL-LHC. Several 4-chip MALTA modules have been built using Al wedge wire bonding to demonstrate the direct transfer of data from chip-to-chip and to read out the data of the entire module via one chip only. Novel technologies such as Anisotropic Conductive Films (ACF) and nanowires have been investigated to build a compact module. A lightweight flex with 17 μm trace spacing has been designed, allowing compact packaging with a direct attachment of the chip connection pads to the flex using these interconnection technologies. This contribution shows the current state of our work towards a flexible, low material, dense and reliable packaging and modularization of pixel detectors.

description: Numerical integration of ODEs by standard numerical methods reduces a continuous time problems to discrete time problems. Discrete time problems have intrinsic properties that are absent in continuous time problems. As a result, numerical solution of an ODE may demonstrate dynamical phenomena that are absent in the original ODE. We show that numerical integration of system with one fast rotating phase lead to a situation of such kind: numerical solution demonstrate phenomenon of scattering on resonances that is absent in the original system.
