description: Dedicated class structures are fundamental for the R/Bioconductor ecosystem. In microbiome research, the phyloseq class has become a commonly accepted standard. However, recent developments in Bioconductor classes and growing sample sizes have opened up new opportunities and requirements to extend this popular format in order to address emerging research needs. Extended support is needed for instance for hierarchically structured data, linking with other data types, and for general performance optimization.

 We propose MicrobiomeExperiment as a novel class structure for microbiome data. This extends the TreeSummarizedExperiment and SingleCellExperiment classes, which provide thoroughly tested tools for hierarchical data, spanning both sample and feature spaces. The new class adds support for additional feature information that is specifically relevant for microbiome experiments; it allows a seamless incorporation of more detailed sequence information based on existing classes such as the DNAStringSet(List). The class inherits support for sparse matrices and multiple assays while providing improvements in speed and memory compared to the currently available solutions for microbiome data. Importantly, it provides conversion methods from the widely used phyloseq class as well as other raw data types, thus enabling seamless conversion.

 By linking microbiome data more tightly to other already established and strongly supported Bioconductor classes, we hope to reduce overlapping development efforts, improve the interoperability of available tools, and simplify the addition and ensure the long-term sustainability of the new tools. This is aimed at solving shortcomings in the current microbiome R ecosystem and it has the potential to become a widely accepted standard for microbiome data in the R/Bioconductor ecosystem. The class structure and the associated package ecosystem are now under active development as a joint effort of multiple research teams, and feedback from the community will be highly valued.

Crude Oil Hedging - An Application of Currency Translated Options to Canada's Oil
Creators: name: Obour, Paul
Publisher: name: Graduate Studies
Year: 2012
Subjects: subject: Mathematics
subject: FOS: Mathematics
subject: Finance

description: This study presents a review of pricing and hedging currency translated options. It is intended for Canadian Oil producers seeking to mitigate their production and F/X risks. Currency translated options are options based upon a foreign asset but with a payout that occurs in another currency. Different types of currency translated options are covered: Flexos, Compos or joint options and Quantos. A special emphasis is placed on the comparison between the first and the third versions of this product since the latter is the only version that completely eliminates the currency risk to the commodity/equity investor. Any oil producer or consumer can diversify its risks by transforming its complete dependence on spot oil prices into a variety of exposures to forward, futures, and options markets. In the light of these transformations, we analyze the efficiency of linearly delta hedging with Flexos and Quantos and further examine the hedging implications if any.

description: Within a decade of fruitful developments, metamaterials became a prominent area of research, bridging theoretical and applied electrodynamics, electrical engineering and material science. Being man-made structures, metamaterials offer a particularly useful playground to develop novel interdisciplinary concepts. Here we demonstrate a novel principle in metamaterial assembly which integrates electromagnetic, mechanical, and thermal responses within their elements. Through these mechanisms, the conformation of the meta-molecules changes, providing a dual mechanism for nonlinearity and offering nonlinear chirality. Our proposal opens a wide road towards further developments of nonlinear metamaterials and photonic structures, adding extra flexibility to their design and control.

description: The COVID-19 pandemic has had a profound impact on various aspects of life in the Philippines, affecting the economy, physical health, and mental well-being. This global health crisis has led to increased anxiety and psychological distress among healthcare professionals and the general population. As of July 9, 2021, there have been 1,455,585 confirmed COVID-19 cases and 25,650 deaths in the Philippines, highlighting the significant burden of the virus.
Healthcare institutions, particularly for frontliners, have become high-risk environments due to the additional workloads and increased exposure to health hazards. This situation has taken a toll on the mental health of medical professionals. Studies from other countries, such as Albania and Germany, during previous pandemics have also reported anxiety and psychological distress among healthcare workers and patients.
This crisis underscores the importance of identifying and addressing the immediate psychological needs of patients and healthcare professionals. Understanding the mental health challenges arising from the pandemic is crucial for developing effective strategies and support systems to mitigate the psychological impact.

Subjects: subject: Medicine and Surgery

subject: Whole Slide Imaging

description: This thesis examines the use of whole slide imaging (WSI) analysis and staining techniques to maximize the amount of data from an entire glass slide. Although WSI is used in research, data are primarily from specimens obtained from biopsy rather than full thickness sections. To date the use of WSI has not been used to assess the histology of blood vessels. WSI is a method for quantifying components of tunica media and was found to be consistent with the qualitative descriptions in the literature. This data concordance was then applied to compare non-diseased aorta with Type A dissecting aorta. The results demonstrated differences in the comparison between the two vessels. Models derived from pixel-level informatics have the potential to be used for histopathological assessment of vascular wall content.
The effects of low molar concentrations of bisphenol A on neuron viability and survival under neurotoxic stress
Creators: name: Tong, Jade Pui Wai
Publisher: name: University of British Columbia
Year: 2010

description: Bisphenol A (BPA) is an ubiquitous environmental xenoestrogen excreted in the urine of 95-99\% of humans studied. In this investigation, we examine the effects of 1mM to 10fM concentrations of BPA on the viability of rat cortical neurons under acute (5h) and chronic (DIV3-9, DIV3-15) exposure conditions. Post-exposure, we also challenged the cultures with an oxidative or excitotoxic stress to determine whether BPA conferred neuroprotection, susceptibility or neither to the challenged cultures. Finally, we studied the effects of different concentrations of BPA on the activation of SREBP~1, a transcription factor that regulates many genes with important effects on neuron function. We found that 1mM and 500uM BPA are neurotoxic under chronic exposure, but only 1mM BPA decreased cell viability after 5h. Acute and chronic exposure to BPA conferred neither neuroprotection nor susceptibility to oxidative or excitotoxic stress in the neuron cultures. Five hours exposure to 10pM and 1pM BPA increased SREBP~1 activation two-fold. In DIV9 cultures, 10pM BPA stimulated a maximal three-fold SREBP~1 activation at 8h post exposure, while at DIV15, 10pM BPA stimulated a maximal two-fold SREBP~1 activation at 5h post exposure. High, physiologically irrelevant concentrations of BPA induce neuronal cell death, and while sublethal concentrations do not predispose cultures to oxidative or excitotoxic stress, they also do not confer neuroprotection as a true estrogen, estradiol, would. Sublethal concentrations of BPA activate SREBP~1 in a hormetic manner, resulting in a non-monotonic dose response curve.

description: To construct a set of scientific and effective quality evaluation indicators of continuing care for children with asthma, and to promote the development of continuing care for children with asthma towards a more specialized and standardized direction. Through literature research and semi-structured interview, the item pool of evaluation index was drawn up, and the first draft of expert inquiry questionnaire was formed based on the three-dimensional quality theoretical model of structure-process-result, and the construction of quality evaluation index was completed through two rounds of expert inquiry and analytic hierarchy process. The effective recovery rate was 94.44% in the first round and 100.00% in the second round, the expert authority coefficient was 0.852 and 0.863, and the Kendal coordination coefficient was 0.129 and 0.126, respectively (P < 0.01). Finally, the evaluation index of continuing care quality for children with asthma was formed, including 3 first-level indicators, 9 second-level indicators and 36 third-level indicators, and then the weight and combination weight of each index were obtained by AHP. The evaluation index of continuing care quality for children with asthma is scientific and specific, which is of great significance to the improvement of continuing care quality for children with asthma.

description: We report the results of a low frequency radio variability and slow transient search using archival observations from the Very Long Array. We selected six 325 MHz radio observations from the spring of 2006, each centered on the Spitzer-Space-Telescope Wide-area Infrared Extragalactic Survey (SWIRE) Deep Field: 1046+59. Observations were spaced between 1 day to 3 months, with a typical single-epoch peak flux sensitivity below 0.2 \mjb near the field pointing center. We describe the observation parameters, data post-processing, and search methodology used to identify variable and transient emission. Our search revealed multiple variable sources and the presence of one, day-scale transient event with no apparent astronomical counterpart. This detection implies a transient rate of 1$\pm$1 event per 6.5 $°^2$ per 72 observing hours in the direction of 1046+59 and an isotropic transient surface density $Σ= 0.12 °^{-2}$ at 95% confidence for sources with average peak flux density higher than 2.1 mJy over 12 hr.

Effect of Disorder in BCS-BEC Crossover

description: In this article we have investigated the effect of weak random disorder in the BCS-BEC crossover region. The disorder is included in the mean field formalism through NSR theory of superconducting fluctuations. A self consistent numerical solution of the coupled equations involving the superfluid gap parameter and density as a function of the disorder strength, albeit unaffected in the BCS phase, yields a depleted order parameter in the BEC regime and an interesting nonmonotonic behavior of the condensate fraction in the vicinity of the unitary region, and a gradual depletion thereafter, as the pairing interaction is continuously tuned across the BCS-BEC crossover. The unitary regime thus demonstrates a robust paradigm of superfluidity even when the disorder is introduced. To support the above feature and shed light on a lingering controversial issue, we have computed the behavior of the sound mode across the crossover that distinctly reveals a suppression of the sound velocity. We also find the Landau critical velocity that shows similar nonmonotonicity as that of the condensate fraction data, thereby supporting a stable superfluid scenario in the unitary limit.
Unwilling to Continue, Ordered to Advance: An Examination of the Contributing Factors Toward, and Manifestations of, 'War Weariness' in the Canadian Corps during the Hundred Days Campaign of the First World War

Subjects: subject: Canadian

subject: 'War Weariness'

description: This thesis examines the contributing factors and manifestations of ‘war weariness’ in the Canadian Corps during the final months of the Great War. The starting point is the acknowledgment that all armies on the Western Front were suffering from ‘war weariness’ by 1918. The historiography for the Canadian Corps, however, ignores or denigrates this issue in its analysis of the operational achievements of the Corps, primarily because of the Victory Campaign narrative and the Colony-to-Nation paradigm. The thesis identifies the preconditions for ‘war weariness,’ namely, the nature, pace and intensity of the Hundred Days, the resultant heavy casualties, and the fact that the majority of the Corps’ troops were long-serving veterans. The final section examines the manifestations of ‘war weariness’ in the Corps during the final months of the war and after the signing of the Armistice, focussing mostly upon instances of insubordination, indiscipline and the killing of German prisoners.
The Origin of Kepler's Supernova Remnant

description: It is now well established that Kepler's supernova remnant is the result of a Type Ia explosion. With an age of 407 years, and an angular diameter of ~ 4', Kepler is estimated to be between 3.0 and 7.0 kpc distant. Unlike other Galactic Type Ia supernova remnants such as Tycho and SN 1006, and SNR 0509-67.5 in the Large Magellanic Cloud, Kepler shows evidence for a strong circumstellar interaction. A bowshock structure in the north is thought to originate from the motion of a mass-losing system through the interstellar medium prior to the supernova. We present results of hydrodynamical and spectral modeling aimed at constraining the circumstellar environment of the system and the amount of 56Ni produced in the explosion. Using models that contain either 0.3 M_sun (subenergetic) or 1 M_sun (energetic) of 56Ni, we simulate the interaction between supernova Ia ejecta and various circumstellar density models. Based on dynamical considerations alone, we find that the subenergetic models favor a distance to the SNR of < 6.4 kpc, while the model that produces 1 M_sun of 56Ni requires a distance to the SNR of > 7 kpc. The X-ray spectrum is consistent with an explosion that produced ~ 1 M_sun of 56Ni, ruling out the subenergetic models, and suggesting that Kepler's SNR was a SN 1991T-like event. Additionally, the X-ray spectrum rules out a pure 1/r^2 wind profile expected from isotropic mass loss up to the time of the supernova. Introducing a small cavity around the progenitor system results in modeled X-ray spectra that are consistent with the observed spectrum. If a wind shaped circumstellar environment is necessary to explain the dynamics and X-ray emission from the shocked ejecta in Kepler's SNR, then we require that the distance to the remnant be greater than 7 kpc.

description: This dissertation examines infant feeding practices and diet in human skeletal remains from Kalamaki (Bronze Age, 3100-1065 BC), Nemea and Stymphalos (Byzantine, AD 5th-6th centuries). Dietary life histories were constructed for 79 individuals by analyzing stable carbon and nitrogen isotopes in collagen extracted from serial sections of dentin (n = 530) and from bones (n = 29). The isotopic evidence was compared to the written sources outlining dietary practices of the ancient Greeks. Using multiple sources, this dissertation aims to explore variation in infant feeding practices and subsistence among individuals, between the sexes, and over time. The isotopic evidence demonstrated that most individuals were consuming breast milk during infancy and were fully weaned by two and three years of age. Variation existed, as some individuals were never breastfed during infancy. Comparison of infant feeding practices between the sexes showed that males and females from all three sites were fully weaned around the same age, which suggests boys and girls were treated equally, with respect to infant feeding practices. The post-weaning diet was comprised of C3 terrestrial based resources, which, as indicated by the written sources consisted of cereals, fruits, vegetables, dairy products, and meat. Diets were not homogenous, as many individuals displayed moderate to large isotopic shifts. One individual from Nemea was reliant on a marine diet, which suggests he lived elsewhere during childhood. Inter-individual comparisons showed that children were given a limited range of foods at Kalamaki, in contrast to the dietary breadth observed among individuals from Nemea and Stymphalos. Furthermore, several boys consumed greater amounts of high-protein foods than girls, which suggests boys were favoured in some housholds at Nemea. Temporal comparisons showed that diets during the Byzantine Empire were more heterogeneous and included greater amounts of meat with minor supplementation from marine fish and C4 grains such as millet. Socio-cultural changes such as trade, mobility, and markets, explain the dietary breadth observed during the Early Byzantine Empire. Overall, the benefits of using dentin serial section analysis were highlighted. Combined with the written sources, it was possible to uncover and understand the life history of the ancient Greeks.

Gemäss Ergebnissen dieser explorativen Studie (N=19) wird sie von Lehramtsstudierenden der Primarstufe kurz vor Abschluss der schweizerischen Bachelorausbildung ungenügend wahrgenommen. Studierende deuten im Gegensatz zu fachlichen und fachdidaktischen Expertinnen Raumveränderungen eher fremdverursacht und fremdgesteuert, sie vermeiden bei unterrichtspraktischen Überlegungen Inhalte, die zukunftsgerichtet und somit besonders bedeutsam sind. Was tun in der Ausbildung? Der Vergleich kollektiver Deutungsmuster von Studierenden und Experten klärt den Lernbedarf: Lehramtsstudierende sollten das unzureichende Raumverständnis des ‚Räume Betrachtens‘ (individuell distanzierte Perspektive) dahingehend erweitern, dass sie sich selbst – durch alltägliche konsumtive Handlungen – als mitgestaltender und somit mitverantwortlicher Teil des Raumes begreifen (kooperativ teilhabende Perspektive).

Outcomes evaluation in knee arthroplasty for the treatment of osteoarthritis
Creators: name: Sweeney, Mary Kathleen
Publisher: name: University of British Columbia
Year: 2010

description: Objectives: The primary objective was to evaluate differences in outcome between unicompartmental knee arthroplasty (UKA) and total knee arthroplasty (TKA) with respect to total WOMAC and OKS scores. In order to properly evaluate outcomes following both UKA and TKA valid and responsive instruments are needed. Therefore the second objective was to assess the construct validity and responsiveness of the SF-6D and the WOMAC derived HUI3 in patients undergoing either UKA or TKA. Lastly, the third objective was to evaluate any differences in the effect of socioeconomic status in outcomes following UKA compared to TKA. Methods: A retrospective analysis was conducted to evaluate outcomes following knee arthroplasty on data collected between July 2000 and December 2008 on all patients requiring either UKA or TKA. Patients completed the WOMAC, OKS and SF-12 preoperatively and then subsequently at 3 and 6 months post-surgery. The Pearson correlation coefficient and intraclass correlation coefficient (ICC) were used to measure the correlation between the OKS, WOMAC, SF-6D and HUI3. Responsiveness was evaluated using a distribution based evaluation and an anchor-based method. A three level hierarchical linear model was used to model the total WOMAC scores and OKS as a function of group (UKA or TKA) and time. A similar model was used to investigate whether differences in total WOMAC or OKS between UKA and TKA occur across socioeconomic groups. Results: The WOMAC derived HUI3 and SF-6D appear to be valid measures of HRQL in this patient sample. The SF-6D was not as responsive as the HUI3 but demonstrated a good ability to identify patients who had improved. There were no significant differences in HRQL between UKA and TKA and socioeconomic status did not have a significant effect on HRQL following knee arthroplasty. Conclusions: Both the HUI3 and SF-6D appeared to be valid and responsive measures in this patient sample. However, further study looking at the interchangeability of the WOMAC derived HUI3 with the HUI3 itself is needed. No differences in HRQL between UKA and TKA were noted and there were no differences in outcome between UKA and TKA across SES groups.

description: The benefits of an ultra stable oscillator are studied in this thesis. The factors that limit the coherent integration period extension given an ultra stable oscillator are first analysed. Coherent integration of over 100 s is demonstrated using such an oscillator and assistance data. It is shown that there is no significant benefit in using precise instead of broadcast ephemeris to perform long coherent integration. It is demonstrated that the position accuracy indoors is limited by multipath errors after the signal sensitivity is resolved. Dealing with weak signal indoors when the signal is subject to several reflections, experimental results show that there is no added advantage in having large and costly antennas instead of small helix antennas. A ray-tracing technique is proposed to study Doppler differences (DD) between LOS and NLOS signals and it is shown how ray-tracing simulation derived DDs can be used as input to multipath mitigation methods. The ray-tracing simulation results are confirmed using a ground multipath model and actual measurements. Using 120 s of coherent integration on GPS signals it is shown that LOS and NLOS signals can be separated in the frequency domain even for a static case, leading to improvement in measurement accuracy. Three possible ways of using ray-tracing based DD as a means of alleviating multipath errors are proposed. Experimental results show that it is possible to increase the probability of LOS and NLOS signal separation in the frequency domain with a few seconds of coherent integration using a slowly moving antenna, as opposed to a few hundred seconds for a static antenna. Positioning results suggest that the moving case has a higher probability of improving accuracy compared to that of the static case.

description: We present the discovery of two ultra-luminous supernovae (SNe) at z ~ 0.9 with the Pan-STARRS1 Medium-Deep Survey. These SNe, PS1-10ky and PS1-10awh, are amongst the most luminous SNe ever discovered, comparable to the unusual transients SN 2005ap and SCP 06F6. Like SN 2005ap and SCP 06F6, they show characteristic high luminosities (M_bol ~ -22.5 mag), blue spectra with a few broad absorption lines, and no evidence for H or He. We have constructed a full multi-color light curve sensitive to the peak of the spectral energy distribution in the rest-frame ultraviolet, and we have obtained time-series spectroscopy for these SNe. Given the similarities between the SNe, we combine their light curves to estimate a total radiated energy over the course of explosion of (0.9-1.4) x 10^51 erg. We find photospheric velocities of 12,000-19,000 km/s with no evidence for deceleration measured across ~3 rest-frame weeks around light-curve peak, consistent with the expansion of an optically-thick massive shell of material. We show that, consistent with findings for other ultra-luminous SNe in this class, radioactive decay is not sufficient to power PS1-10ky, and we discuss two plausible origins for these events: the initial spin-down of a newborn magnetar in a core-collapse SN, or SN shock breakout from the dense circumstellar wind surrounding a Wolf-Rayet star.

description: The collapse of an isolated, uniform and spherical cloud of self-gravitating particles represents a paradigmatic example of a relaxation process leading to the formation of a quasi-stationary state in virial equilibrium. We consider several N-body simulations of such a system, with the initial velocity dispersion as a free parameter. We show that there is a clear difference between structures formed when the initial virial ratio is b_0 =2K_0/W_0 < b_0^c ~ -1/2 and b_0> b_0^c. These two sets of initial conditions give rise respectively to a mild and violent relaxation occurring in about the same time scale: however in the latter case the system contracts by a large factor, while in the former it approximately maintains its original size. Correspondingly the resulting quasi equilibrium state is characterized by a density profile decaying at large enough distances as ~1/r^4 or with a sharp cut-off. The case b_0b_0^c is the ejection of particles and energy, which is not captured by such a theoretical approach: for this case we introduce a simple physical model to explain the formation of the power-law density profile. This model shows that the behavior n(r) ~1/r^4 is the typical density profile that is obtained when the initial conditions are cold enough that mass and energy ejection occurs. In addition, we clarify the origin of the critical value of the initial virial ratio b_0^c.

description: The under exploitation of the available resources risks to be one of the main problems for a computing center. The growing demand of computational power necessarily entails more complex approaches in the management of the computing resources, with particular attention to the batch queue system scheduler. In a heterogeneous batch queue system, available for both serial single core processes and parallel multi core jobs, it may happen that one or more computational nodes composing the cluster are not fully occupied, running a number of jobs lower than their actual capability. A typical case is represented by more single core jobs running each one over a different multi core server, while more parallel jobs - requiring all the available cores of a host - are queued. A job rearrangement executed at runtime is able to free extra resources, in order to host new processes. We present an efficient method to improve the computing resources exploitation.

description: In the literature of risk theory, two risk models have emerged to have been studied extensively. These are the Classical Compound Poisson risk model and the Continuous Time Renewal risk model also referred to as Sparre-Andersen model. The focus of this thesis is the latter and in the Sparre-Andersen risk model, the distribution of claim inter-arrival times (T) and the claim sizes (amounts) (X) are assumed to be independent. This assumption is not only too restrictive but also inappropriate for some real world situations like collision coverages under automobile insurance in cities with hash weather conditions. In this thesis, the assumption of independence between T and X for different classes of bivariate distributions is relaxed prior to computing the ultimate ruin probability. Also, the effect of correlation on ruin probability is investigated. Correlation is introduced through the use of the Moran and Downton's bivariate Exponential distribution. The underlying method in the entire modeling process is the Wiener-Hopf factorization technique, details of which are covered in chapter 2. The main results are covered in chapters 3, 4, 5, 6 and 7. In all of these chapters, we assume T to follow an Exponential distribution while X is Gamma distributed with shape parameter 2 in chapter 3. In chapter 4, X follows Gamma distribution with shape parameter (m) where m is greater than 2. In chapter 5, a mixture of Exponential (Hyper Exponential) distributions is used to model X. The Pareto distribution is used to model X in chapter 6, in the modeling process however, the cummulative distribution function (CDF) of W=X-cT where (X,T) is Exponential-Pareto distribution is approximated by the CDF of Y=X-cT where (X,T) is Exponential-Hyper Exponential distribution and Exponential- Gamma (m) distribution with the main estimation approach being method of moments estimation. Chapter 7 follows somewhat a different approach by employing asymmetric finite mixture of Double Exponential distributions and the EM algorithm prior to computing the ruin probability. In some of these situations, an explicit expression for the ultimate ruin probability is obtained and in chapters 3 and 5, we show that increasing correlation between T and X diminishes the impact of ruin probability. Also, in situations where an explicit expression for the ultimate ruin probability is not possible, excellent approximation is obtained. Chapter 8 summarizes the entire thesis, provides concluding remarks and future research.
Pole shift control based adaptive power system stabilizer for a superconducting generator

Subjects: Engineering--Electronics and Electrical

description: Over the past few decades, an international effort has been undertaken to develop electric generators using rotors with super-conducting windings. The main differences between superconducting generators (SCGs) and the conventional generators are that (i) the SCG has a double rotor screen and (ii) the SCG’s field windings on the rotor are made up of super-conductors that have zero resistance at cryogenic temperature and, therefore, completely eliminate resistive losses from the rotor. In order to enhance power system stability, a conventional power system stabilizer (CPSS) is commonly applied to the conventional generator excitation system to damp oscillations. In an SCG, due to the long field time-constant and the shielding effect of the double rotor screen, it is not effective to control through the generator excitation system. A possibility, considered here, is to control the SCG through an electro-hydraulic governor as its time-constant is much less than that of the field winding. The objective of this research is to test the performance of an adaptive power system stabilizer for a SCG based on the pole-shift linear feedback control algorithm and acting through the SCG electro-hydraulic governor. The system considered is a single SCG – infinite-bus power system driven by a three stage turbine that includes a re-heater. The turbine is controlled by an electro-hydraulic governor. A third order autoregressive moving average (ARMA) model is used to represent the plant that can be controlled by an adaptive pole-shift controller through the electro-hydraulic governor

description: In this parer, q-deformed oscillator for pseudo-Hermitian systems is investigated and pseudo-Hermitian appropriate coherent and squeezed states are studied. Also, some basic properties of these states is surveyed. The over-completeness property of the para-Grassmannian pseudo-Hermitian coherent states (PGPHCSs) examined, and also the stability of coherent and squeezed states discussed. The pseudo-Hermitian supercoherent states as the product of a pseudo-Hermitian bosonic coherent state and a para-Grassmannian pseudo-Hermitian coherent state introduced, and the method also developed to define pseudo-Hermitian supersqueezed states. It is also argued that, for q-oscillator algebra of $k+1$ degree of nilpotency based on the changed ladder operators, defined in here, we can obtain deformed $SU_{q^2}(2)$ and $SU_{q^{2k}}(2)$ and also $SU_{q^{2k}}(1,1)$. Moreover, the entanglement of multi-level para-Grassmannian pseudo-Hermitian coherent state will be considered. This is done by choosing an appropriate weight function, and integrating over tensor product of PGPHCSs.

Model Uncertainty in Foreign Direct Investment: Greenfield versus Mergers and Acquisitions

description: Foreign direct investment (FDI) is marked with model uncertainty due to different theories and conclusions as to what variables should be included in the model. Using two specifications; the global sample and developing countries, I utilize the Bayesian Model Averaging (BMA) technique to determine the robust variables. Since the FDI modes; Greenfield Investment (GFI) and Mergers \& Acquisitions (M\&A) have different impacts on the economy, the BMA method is used to tackle separately model uncertainty in the two modes. My findings show that some of the variables identified by previous literature as determinants of FDI are not robust. In examining the FDI modes, I show that they behave in different ways having only six determinants in common. This study provides a better understanding of the robust determinants of FDI and the different ways GFI and M\&A responds to policies.
The Role of the Tight Junction in the Serine Protease-Mediated Increase in Epithelial Barrier Function

description: One of the main contributors to intestinal epithelial barrier function is the composition of the tight junction (TJ). In inflammatory bowel disease (IBD), inflammatory mediators induce disruption of the TJ and may contribute to pathogenesis. The apical addition of the serine proteases trypsin or matriptase to intestinal epithelial cell lines induces a rapid and sustained increase in transepithelial electrical resistance (TER). However, the mechanism behind this effect is incompletely understood. Determining how barrier function is modulated by serine proteases may provide further avenues to maintain barrier function and remission in IBD. It was hypothesized that serine proteases induce an increase in barrier function through modification of the TJ, and that treatment could reverse barrier disruption. Using the intestinal epithelial SCBN cell line, it was found that the response to serine proteases was independent of protease-activated receptor 2 (PAR2) and myosin regulatory light chain (MLC) phosphorylation, and mass spectrometry did not reveal a target that was being cleaved by serine proteases. Serine proteases did not enhance the recovery of barrier function after calcium depletion, and the barrier had to recover sufficiently for trypsin or matriptase to have an effect. Treatment by TNFα and IFNγ induced a concentration-dependent decrease in barrier function and prevented the increase in TER by serine proteases. Therefore, a functional tight junction is needed for the serine protease-induced increase in TER. Knockdown of occludin by siRNA prevented the increase in TER in response to serine proteases, and the membrane mobility of occludin was increased following trypsin treatment, as assessed by fluorescence recovery after photobleaching (FRAP). Thus, occludin is a key TJ protein in the serine protease mediated increase in TER. This work demonstrates that although serine proteases may not enhance barrier function in epithelia that are already disrupted, understanding the mechanisms by which they modify the junction could be used as targets for potential therapies to maintain remission.
