description: The $Kπ$ vector form factor, $F_+^{Kπ}$, used to reproduce the Belle spectrum of $\tauKpi$ decays is described by means of a three-times subtracted dispersion relation also incorporating constraints from $K_{l3}$ decays. The slope and curvature of $F_+^{Kπ}$ are fitted to the data yielding $λ_+'=(25.49 \pm 0.31) \times 10^{-3}$ and $λ_+"= (12.22 \pm 0.14) \times 10^{-4}$. The pole parameters of the $K^*(892)^\pm$ are found to be $m_{K^*(892)^\pm}= 892.0\pm 0.5$ MeV and $Γ_{K^*(892)^\pm}= 46.5 \pm1.1$ MeV. The phase-space integrals relevant for $K_{l3}$ analyses and the $P$-wave isospin-1/2 $Kπ$ phase-shift threshold parameters are also calculated.

description: The contemporary stress state in the upper crust is of great interest for geotechnical applications and basic research alike. However, our knowledge of the crustal stress field from the data perspective is limited. For Germany basically two datasets are available: orientations of the maximum horizontal stress (SHmax) and the stress regime as part of the World Stress Map (WSM) database as well as a complementary compilation of stress magnitude data of Germany and adjacent regions. However, these datasets only provide pointwise, incomplete and heterogeneous information of the 3D stress tensor. Here, we present a geomechanical–numerical model that provides a continuous description of the contemporary 3D crustal stress state on a regional scale for Germany. The model covers an area of about 1000×1250 km2 and extends to a depth of 100 km containing seven units, with specific material properties (density and elastic rock properties) and laterally varying thicknesses: a sedimentary unit, four different units of the upper crust, the lower crust and the lithospheric mantle. The model is calibrated by the two datasets to achieve a best-fit regarding the SHmax orientations and the minimum horizontal stress magnitudes (Shmin). The modeled orientations of SHmax are almost entirely within the uncertainties of the WSM data used and the Shmin magnitudes fit to various datasets well. Only the SHmax magnitudes show locally significant deviations, primarily indicating values that are too low in the lower part of the model. The model is open for further refinements regarding model geometry, e.g., additional layers with laterally varying material properties, and incorporation of future stress measurements. In addition, it can provide the initial stress state for local geomechanical models with a higher resolution.

description: We study the resolved stellar populations of dwarf galaxies in the nearby Centaurus A/M83 group of galaxies. Our goal is to characterize their evolutionary history and to investigate eventual similarities or differences with the dwarf population in other group environments. This work presents the analysis of five late-type (irregular) dwarfs found in the vicinity of the giant spiral M83. Using archival HST/ACS data, we perform synthetic color-magnitude diagram modeling to derive the star formation histories of these late-type dwarfs. The target objects show heterogeneous star formation histories, with average star formation rates of 0.08 to 0.70x10^{-2} M_odot/yr. Some of them present prolonged, global bursts of star formation (~300-500 Myr). The studied galaxies are all metal-poor ([Fe/H] ~-1.4). We further investigate the spatial extent of different stellar populations, finding that the young stars show a clumpy distribution, as opposed to the smooth, broad extent of the old ones. The actively star forming regions have sizes of ~100 pc and lifetimes of >~100 Myr, thus suggesting a stochastic star formation mode for the target dwarf irregular galaxies. The galaxies formed ~20% to 70% of their stars more than ~7 Gyr ago. The studied dwarfs have average star formation rates slightly higher than their analogues in the Local Group, but comparable to those in the M81 group. Our preliminary sample indicates that the neutral gas content of the target dwarfs does seem to be affected by the group environment: galaxies within a denser region have a much lower M_HI/ than the isolated ones, meaning that they will exhaust their gas reservoir more quickly.

description: This paper discusses some topics related to the latest trends in the field of evolutionary approaches to iris recognition. It presents the results of an exploratory experimental simulation whose goal was to analyze the possibility of establishing an Interchange Protocol for Digital Identities evolved in different geographic locations interconnected through and into an Intelligent Iris Verifier Distributed System (IIVDS) based on multi-enrollment. Finding a logically consistent model for the Interchange Protocol is the key factor in designing the future large-scale iris biometric networks. Therefore, the logical model of such a protocol is also investigated here. All tests are made on Bath Iris Database and prove that outstanding power of discrimination between the intra- and the inter-class comparisons can be achieved by an IIVDS, even when practicing 52.759.182 inter-class and 10.991.943 intra-class comparisons. Still, the test results confirm that inconsistent enrollment can change the logic of recognition from a fuzzified 2-valent consistent logic of biometric certitudes to a fuzzified 3-valent inconsistent possibilistic logic of biometric beliefs justified through experimentally determined probabilities, or to a fuzzified 8-valent logic which is almost consistent as a biometric theory - this quality being counterbalanced by an absolutely reasonable loss in the user comfort level.

description: Optical measurements are essential for many microfluidic devices, offering effective, quick, and reliable analysis methods on small sample volumes, for instance on a droplet of blood. In particular, microscopy is a powerful tool for monitoring and analysing cellular behaviour or fluid properties. Furthermore, microscopy is a flexible technique that can also be combined to manipulate cells or particles inside microfluidic channels using laser beams. This document is written to serve as a guideline for researchers and engineers working in the field of microfluidics with optical interfaces. This document aims to provide direction to microfluidic engineers and scientists about what to consider when designing the device to ensure proper function of the optical parts. As this document is created with the help of experts working on a diverse range of microfluidic products, it is expected to be applicable to a wide range of microfluidic products. The diversity in microfluidics applications and technologies is too large to create a comprehensive guideline; this document must be seen as a first step in the design process.

In order to determine the kinematics parameters of a wave, the values of a physical quantity in different space points and their changes in the time should be known. An approach for image processing of registered spectrograms is proposed. A detailed description is made of the steps of this approach, related to recovering CCD pixel values, influenced by cosmic particles, dark image correction and filter parameters determination.

A comparison of the auditory steady-state and auditory brainstem responses to air- and bone-conducted stimuli in infants with hearing loss
Creators: name: Valeriote, Hope
Publisher: name: University of British Columbia
Year: 2015

description: This study investigates how well the air- (AC) and bone-conduction (BC) auditory steady-state response (ASSR) detects conductive hearing loss compared to the gold standard method, the auditory brainstem response (ABR). Similar studies using infants with sensorineural hearing loss have suggested that the ASSR is an effective method for assessing hearing thresholds and detecting hearing loss in infants. This study compares AC and BC ASSR and ABR thresholds in infants with normal hearing and conductive loss. Twenty-three normal hearing infants and 15 infants with conductive hearing loss (0-6 months) were assessed using the ABR and 80-Hz ASSR elicited to AC and BC stimuli (AM²). Mean thresholds for normal hearing infants were : 500 Hz (i) AC ABR : 25 dB nHL, (ii) BC ABR : 10 dB nHL, (iii) AC ASSR : 30 dB HL , (iv) BC ASSR : 17 dB HL and 2000 Hz (i) AC ABR : 18 dB nHL, (ii) BC ABR : 15 dB nHL, (iii) AC ASSR : 20 dB HL, (iv) BC ASSR : 26 dB HL. For infants with confirmed conductive hearing loss, 500 Hz thresholds air-conduction ABR thresholds increased to approximately 48 dB nHL, while bone-conduction ABR thresholds were approximately 12 dB nHL. Air-conduction ASSR thresholds for infants with conductive hearing loss increased to approximately 37 dB HL and bone-conduction thresholds were approximately 15 dB HL. Overall, mean bone-conduction thresholds were similar between groups, while there was a trend for mean air-conduction thresholds to be higher for infants with conductive hearing loss than infants with normal-hearing for both ABR and ASSR testing methods. Previously suggested “normal levels” in the literature appear to be too high to detect mild conductive hearing loss at 500 Hz. Normal levels of 40 and 30 dB HL is suggested for air- and bone conduction 500 Hz ASSR, respectively, to be more accurate in detecting mild hearing losses. Even with an adjusted “normal level”, it appears to be difficult to use the ASSR to differentiate between normal hearing and mild conductive hearing loss. More research is needed using infants with varying degrees of hearing loss at multiple frequencies.

description: We consider new Suzaku data for NGC 3516 taken during 2009, along with other recent X-ray observations of the source. The cumulative characteristics of NGC 3516 cannot be explained without invoking changes in the line-of-sight absorption. Contrary to many other well-studied Seyfert galaxies, NGC 3516 does not show a positive lag of hard X-ray photons relative to soft photons over the timescales sampled. In the context of reverberation models for the X-ray lags, the lack of such a signal in NGC 3516 is consistent with flux variations being dominated by absorption changes. The lack of any reverberation signal in such a highly variable source disfavors intrinsic continuum variability in this case. Instead, the colorless flux variations observed at high flux states for NGC 3516 are suggested to be a consequence of Compton-thick clumps of gas crossing the line-of-sight.

description: Studies of platelet function in surgical patients often involve both arterial and venous sampling. Possible effects of different sampling sites could be important, but have not been thoroughly investigated. We aimed to compare platelet function in arterial and venous blood samples using a novel flow cytometry protocol and impedance aggregometry. Arterial and venous blood was collected before anesthesia in 10 patients undergoing cardiac surgery of which nine was treated with acetylsalicylic acid until the day before surgery. Flow cytometry included simultaneous analysis of phosphatidylserine exposure, active conformation of the fibrinogen receptor (PAC-1 binding), α-granule and lysosomal release (P-selectin and LAMP-1 exposure) and mitochondrial membrane integrity. Platelets were activated with ADP or peptides activating thrombin receptors (PAR1-AP/PAR4-AP) or collagen receptor GPVI (CRP-XL). Leukocyte-platelet conjugates and P-selectin exposure were evaluated immediately in fixated samples. For impedance aggregometry (Multiplate®), ADP, arachidonic acid, collagen and PAR1-AP (TRAP) were used as activators. Using impedance aggregometry and in 27 out of 37 parameters studied with flow cytometry there was no significant difference between venous and arterial blood sampling. Arterial blood showed more PAC-1 positive platelets when activated with PAR1-AP or PAR4-AP and venous blood showed more monocyte-platelet and neutrophil-platelet conjugates and higher phosphatidylserine exposure with CRP-XL alone and combined with PAR1-AP or PAR4-AP. We found no differences using impedance aggregometry. In conclusion, testing of platelet function by flow cytometry and impedance aggregometry gave comparable results for most of the studied parameters in venous and arterial samples. Flow cytometry identified differences in PAC-1 binding when activated with PAR1-AP, exposure of phosphatidyl serine and monocyte/neutrophil-platelet conjugates, which might reflect differences in blood sampling technique or in flow conditions in this patient cohort with coronary artery disease. These differences might be considered when comparing data from different sample sites, but caution should be exercised if a different protocol is used or another patient group is studied.

Implementation and verification of a flexible optical tracker
Creators: name: Semple, Mark Joseph
Publisher: name: University of British Columbia
Year: 2015

description: Despite being demonstrably better than conventional surgical techniques with regards to implant alignment and outlier reduction, computer navigation systems have not faced widespread adoption in surgical operating rooms. We believe that one of the reasons for the low uptake stems from the bulky design of the optical tracker assemblies. These trackers must be rigidly fixed to a patient’s bone and they occupy a significant portion of the surgical workspace, which makes them difficult to use. In this thesis we introduce the design for a new optical tracker system, and subsequently we evaluate the tracker’s performance. The novel tracker consists of a set of low-profile flexible pins that can be placed into a rigid body and individually deflect without greatly affecting the pose estimation. By relying on a pin’s stiff axial direction while neglecting lateral deviations, we gain sufficient constraint over the underlying body. We used an unscented Kalman filter based algorithm as a recursive body pose estimator that can account for relative marker displacements. We assessed our tracker’s performance through a series of simulations and experiments inspired by a total knee arthroplasty. We found that the flexible tracker performs comparably to conventional trackers with regards to accuracy and precision, with tracking errors under 0.3mm for typical operating conditions. The tracking error remained below 0.5mm during pin deflections of up to 40mm. Our algorithm ran at computation speeds greater than real-time at 30Hz which means that it would be suitable for use in real-time applications. We conclude that this flexible pin concept provides sufficient accuracy to be used as a replacement for rigid trackers in applications where its lower profile, its reduced invasiveness and its robustness to deflection are desirable characteristics.

Cell death dynamics monitoring using Raman micro-spectroscopy
Creators: name: Karimbabanezhadmamaghani, Pooya
Publisher: name: University of British Columbia
Year: 2015

description: Biopharmaceuticals play a crucial role in curing diseases like Cancer and diabetes. Bioreactors are the heart of the industry. Cell losses due to cell death such as apoptosis and necrosis in the bioreactor decreases production efficiency and subsequently increases the cost of production. Furthermore, the study of apoptosis and necrosis cell death mechanisms has a great scientific and clinical importance in cancer therapy. In this project, Raman micro-spectroscopy is used to study apoptosis and necrosis in Chinese’s Hamster Ovary (CHO) cells that are one the main host cell lines used in the production of biopharmaceuticals. Apoptosis and Necrosis were induced in CHO cells using camptothecin and oxygen and glucose deprivation. The changes in the chemical composition of these enriched apoptotic and necrotic cell cultures were then analyzed using Raman spectroscopy which revealed novel biological concepts of the cell death process. Moreover, highly distinguishing Raman characteristics were identified for each death mode. These observations made by Raman spectroscopy were confirmed using a broad range of conventional and advanced biological assays in the field ranging from FACS analysis and fluorescent dyes to fluorescence microscopy. Studying Raman Spectra gave a clear image about DNA, RNA and Protein level changes during the process of apoptosis and necrosis in CHO cells. Using Principle Components Analysis (PCR) enabled viable, necrotic, early and late apoptotic populations to be clearly distinguished. This technology may provide the basis for the development of a non-invasive probe to monitor and predict cell death in bioreactor cultures in real-time and possibly allow cultures to avoid entering the cell death phase. In addition, the vast majority of cancer treatment methods involve cell death and apoptosis and, therefore, improving our knowledge about the biology of cell death will help support and advance research and treatment in this area.

description: Time-dependent density functional theory (TD-DFT) and correlated ab initio methods have been applied to the electronically excited states of vitamin B12 (cyanocobalamin or CNCbl). Different experimental techniques have been used to probe the excited states of CNCbl, revealing many issues that remain poorly understood from an electronic structure point of view. Due to its efficient scaling with size, TD-DFT emerges as one of the most practical tools that can be used to predict the electronic properties of these fairly complex molecules. However, the description of excited states is strongly dependent on the type of functional used in the calculations. In the present contribution, the choice of a proper functional for vitamin B12 was evaluated in terms of its agreement with both experimental results and correlated ab initio calculations. Three different functionals, i.e. B3LYP, BP86, and LC-BLYP, were tested. In addition, the effect of relative contributions of DFT and HF to the exchange-correlation functional was investigated as a function of the range-separation parameter, μ. The issues related to the underestimation of charge transfer (CT) excitation energies by TD-DFT was validated by Tozer's L diagnostic, which measures the spatial overlap between occupied and virtual orbitals involved in the particular excitation. The nature of low-lying excited states was also analyzed based on a comparison of TD-DFT and ab initio results. Based on an extensive comparision against experimental results and ab initio benchmark calculations, the BP86 functional was found to be the most appropriate in describing the electronic properties of CNCbl. Finally, an analysis of electronic transitions and a new re-assignment of some excitations are discussed.

Young, alienated, and excluded : youth labour force participation and mental health in Canada
Creators: name: Minh, Anita
Publisher: name: University of British Columbia
Year: 2015

description: This thesis explores the relationship between youth labour force participation and mental health. Unemployment is generally considered to have a negative association with youth mental health. However, few studies have examined youth mental health in association with being both out of the labour force and out of school (OLFS). I hypothesize that OLFS, a state in which youth are no longer job-searching and are not in school, has a negative association with mental health that is weaker in comparison to that of unemployment, which involves active job-searching. I further hypothesize that socioeconomic status (SES) and recession moderate the relationship between youth labour force participation and mental health, such that both unemployment and OLFS have a stronger negative association with mental health in youth of low SES, and during recession. Two empirical studies are presented to test these hypotheses. The first examines whether SES moderates the relationship between youth labour force participation and mental health, across three constructs of mental health : distress, depression, and life-satisfaction. The results indicate that unemployment is associated with poor mental health across all mental health constructs, and has a stronger association with distress among low-SES youth. OLFS is associated with depression only, with a stronger association among low-SES youth. Among high-SES youth, OLFS is also associated with better life-satisfaction. The second study looks at the relationship between youth labour force participation and mental health in the periods before (2003, 2005), during (2008-2009), and after the most recent global recession (2010-2012). The findings suggest that the recession was related to improvements in the mental health of unemployed youth but was not clearly related to the mental health of OLFS youth. The concluding chapter highlights the contributions of this thesis, addresses its limitations, and discusses implications for policy makers and for future analyses. Policy makers should consider the association between OLFS and mental health, and the effect modification by SES, when designing programs for unemployed youth. Future research can examine the mechanisms between OLFS and mental health across macrosocial contexts, and over the life course.

description: Distance measuring is a very important task in digital geometry and digital image processing. Due to our natural approach to geometry we think of the set of points that are equally far from a given point as a Euclidean circle. Using the classical neighbourhood relations on digital grids, we get circles that greatly differ from the Euclidean circle. In this paper we examine different methods of approximating the Euclidean circle in the square grid, considering the possible motivations as well. We compare the perimeter-, area-, curve- and noncompactness-based approximations and examine their realization using neighbourhood sequences. We also provide a table which summarizes our results, and can be used when developing applications that support neighbourhood sequences.

description: Coconut rhinoceros beetle (Oryctes rhinoceros; CRB) was discovered in 2015 in a small outbreak in Honiara, Guadalcanal, Solomon Islands. This was the first record of CRB from Solomon Islands and a response plan was prepared. An awareness programme was launched and where CRB sightings were confirmed, delimitation surveys were carried out. Following the launch of the awareness programme, later in 2015, CRB was also reported from the Shortland Islands in the Western Province. Other islands were surveyed from 2015 to 2020. If CRB presence was confirmed, beetles were collected and analysed for haplotype and presence of the classical biological control agent, Oryctes rhinoceros nudivirus (OrNV). A distribution map and timeline of invasion were developed. The initial populations belonged to two distinct haplotypes: CRB-G (clade IA) in Honiara and CRB-S (clade II) in Shortland Islands. Despite control measures, by 2020 CRB-G had spread to islands in eight provinces and CRB-S had spread to islands in seven provinces. CRB-S and CRB-G co-occur in Guadalcanal and Malaita provinces. In 2019, OrNV was detected from field collected CRB from Guadalcanal and has since spread to Malaita Island. In both cases the virus was detected where CRB-G and CRB-S co-occur. Other outbreak areas in Solomon Islands remain OrNV-free. The two haplotypes appear to have spread following patterns of air and sea movement between the point of origin (CRB-G from Honiara and CRB-S from the Shortland Islands) to other islands/provinces.

description: Spin manipulation using electric currents is one of the most promising directions in the field of spintronics. We used neutron scattering to observe the influence of an electric current on the magnetic structure in a bulk material. In the skyrmion lattice of MnSi, where the spins form a lattice of magnetic vortices similar to the vortex lattice in type II superconductors, we observe the rotation of the diffraction pattern in response to currents which are over five orders of magnitude smaller than those typically applied in experimental studies on current-driven magnetization dynamics in nanostructures. We attribute our observations to an extremely efficient coupling of inhomogeneous spin currents to topologically stable knots in spin structures.

description: We extend the recently discovered duality between MHV amplitudes and the light-cone limit of correlation functions of a particular type of local scalar operators to generic non-MHV amplitudes in planar N=4 SYM theory. We consider the natural generalization of the bosonic correlators to super-correlators of stress-tensor multiplets and show, in a number of examples, that their light-cone limit exactly reproduces the square of the matching super-amplitudes. Our correlators are computed at Born level. If all of their points form a light-like polygon, the correlator is dual to the tree-level amplitude. If a subset of points are not on the polygon but are integrated over, they become Lagrangian insertions generating the loop corrections to the correlator. In this case the duality with amplitudes holds at the level of the integrand. We build up the superspace formalism needed to formulate the duality and present the explicit example of the n-point NMHV tree amplitude as the dual of the lowest nilpotent level in the correlator.

description: We investigate the possibility of the electrical control of spin transfer in monoatomic chains incorporating spin-impurities. Our theoretical framework is the mixed quantum-classical (Ehrenfest) description of the spin dynamics, in the spirit of the s-d-model, where the itinerant electrons are described by a tight-binding model while localized spins are treated classically. Our main focus is on the dynamical exchange interaction between two well-separated spins. This can be quantified by the transfer of excitations in the form of transverse spin oscillations. We systematically study the effect of an electrostatic gate bias V_g on the interconnecting channel and we map out the long-range dynamical spin transfer as a function of V_g. We identify regions of V_g giving rise to significant amplification of the spin transmission at low frequencies and relate this to the electronic structure of the channel.

The role of beta-catenin and the cadherin adhesion complex in synaptic plasticity, learning and addiction
Creators: name: Mills, Fergil
Publisher: name: University of British Columbia
Year: 2017

description: A fundamental property of synapses is their ability to change in response to activity, termed ‘synaptic plasticity’. Synaptic activity can cause long-lasting increases in the strength of synapses (long-term potentiation, or ‘LTP’), as well as decreases in synapse strength (long-term depression or ‘LTD’), both of which are believed to be important for learning and memory. The synaptic adhesion molecules ‘cadherins’ and their intracellular binding partner β-catenin have been identified as key mediators of plasticity at synapses. The cadherin adhesion complex is important for maintaining the strength and stability of synapses, and disruption of cadherin function has been shown to impair long-term potentiation (LTP). However, it remains unclear how increases in cadherin adhesion can affect synaptic function and cognition. This is important in light of studies showing that increases in β-catenin levels and mutations in cadherin adhesion complex proteins are associated with many different neurodegenerative diseases, as well as psychiatric disorders such as drug abuse, raising the possibility that aberrant increases in cadherin adhesion may contribute to cognitive impairments in these disorders. In this dissertation, I examine the effects of increases in cadherin adhesion on different forms of synaptic plasticity in the brain. I demonstrate that increases in β-catenin in the hippocampus can stabilize cadherin at the synaptic membrane and abolish long-term depression (LTD) at synapses, leading to significant impairments in spatial memory flexibility and reversal learning. I also demonstrate a role for cadherin in activity- and drug-induced plasticity in the ventral tegmental area (VTA), a region of the brain important for reward learning which is implicated in addiction, and show that cocaine-mediated conditioned place preference results in redistribution of cadherin and AMPA receptors to excitatory synapses onto dopaminergic neurons in the VTA. Together, these results demonstrate that the β-catenin/cadherin adhesion complex plays an important role in several forms of learning and memory, and that aberrant increases in synaptic adhesion can have a detrimental effect on synaptic plasticity and cognitive function.
Pseudoscalar mesons in nuclei and partial restoration of chiral symmetry

description: Recent theoretical developments of hadrons in nuclei are briefly reviewed in the aspect of chiral symmetry in nuclei. We show a general sum rule connecting in-medium hadronic quantities and quark condensate, emphasizing that both pionic mode and particle-hole excitations in the nuclear medium are responsible for reduction of the chiral condensate in nuclear matter. We also discuss that few-body nuclear systems with kaons are good objects to investigate basic features of kaon-nucleus interactions, showing recent understandings of the structure of Lambda(1405) and possible bound states of KbarNN and KKbarN. We also mention eta mesonic nuclei in connection with chiral symmetry of baryons.

Visitas Pastorais ao concelho da Lourinhã no século XVII
Creators: name: Luís, Maria Dos Anjos Dos Santos Fernandes
Publisher: name: Lusitania Sacra
Year: 2011

description: Este texto tem como objectivo analisar o papel desempenhado pelas visitas pastorais no processo de disciplinamento social, empreendido pela Igreja Católica no período a seguir ao Concílio de Trento. Teve como ponto de partida as fontes produzidas pelas visitações às paróquias do concelho da Lourinhã – livros de devassa e termos de admoestação (1608-1702) –, as quais foram interpretadas à luz do projecto reformista de implementação dos valores do catolicismo. A regularidade com que se realizou a devassa dos “pecados públicos” e o julgamento sistemático dos delitos cometidos, principalmente na primeira metade do século XVII, acabaram por ter um efeito normalizador dos comportamentos sociais.
