description: This dissertation compares the Planetary Boundary Layer ( PBL) height  produced by the Goddard Earth Observing System- version 5 ( GEOS- 5) model with  Cloud- Aerosol Lidar and Infrared Pathfinder Satellite Observations ( CALIPSO). Part  of GEOS- 5 is an Atmosphere Global Circulation Model ( GCM). Developers are  uncertain of the precision of model PBL height predictions ( i. e. climatology), since  there are limited direct observations of the PBL height. Validation of the PBL height  serves as a diagnostic on whether the physics and dynamics packages are correct in  the model. Thus, verification is needed. For the first time ever, PBL heights have  been derived from CALIPSO using a new hybrid standard deviation algorithm, which  in some cases is more sensitive than traditional approaches ( i. e. Haar wavelet  method). Observations made at the UMBC Elastic Lidar Facility ( ELF) have been  used to determine the validity of the satellite- derived PBL estimate. This is the first  global observational study of PBL heights using CALIPSO with match- ups to the  GEOS- 5 MERRA model. Extensive comparisons between the model output and  satellite observations in the western Hemisphere and over Africa gave model-measurement  correlation coefficients between 0.47 - 0.73. Comparisons have been  performed for regions over land and water using clouds, aerosols and mixed cloud-aerosol  features to detect the PBL. The present study provides insight of PBL height  variances in the GEOS- 5 model. A case over the Equatorial Pacific indicates that PBL  heights from the GEOS- 5 model are greater than 25%, on average, than the satellite-derived  PBL parameter. PBL height biases in the Equatorial Pacific may be related to  the General Circulation Model ( GCM) coupling scheme implemented in GEOS- 5.

description: A generalized dynamical equation for the scale factor of the universe is proposed to describe the cosmological evolution, of which the $Λ$CDM model is a special case. It also provides a general example to show the equivalence of the modified equation of state (EOS) and a scalar field model. In the mathematical aspect, the EOS, the scalar field potential $V(ϕ)$, and the scale factor $a(t)$ all have possessed analytical solutions. Such features are due to a simple form invariance of the equation inherited which determines the Hubble parameter. From the physical point of view, this dynamical equation can be regarded as the $Λ$CDM model with bulk viscosity, an existence content in the universe. We employ the SNe Ia data with the parameter $\mathcal{A}$ measured from the SDSS data and the shift parameter $\mathcal{R}$ measured from WMAP data to constrain the parameters in our model. The result is that the contribution of the bulk viscosity, accumulated as an effective dark energy responsible for the current cosmic accelerating expansion, is made approximately ten percent to that of the cosmological constant.

Legitimating media education : from social movement to the formation of a new social curriculum
Creators: name: Lee, Alice Yuet Lin
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study is to understand why and how media education became legitimate in the Ontario educational system in the 1980s. The theoretical focus is on how a new social movement (the new social movement in Ontario) led to the legitimation of a new social curriculum (the media education program). This study on media education in Ontario is contextualized in the epochal shift to the information society. Adopting the approach of historical sociology, it documents the influence of those social forces which gave rise to media education and investigates how key individuals brought media education into schools. In the 1970s and 1980s, the societal shift brought with it rapid development in media technologies and induced new social tensions. This study finds that the conceptualization of the mass media as "invisible curriculum," the ideology of techno-cultural nationalism and the moral controversy over media sex and violence directed public attention to the importance of media literacy. The media literacy movement in Ontario subsequently placed media education in the formal school curriculum. Legitimating media education can be regarded as a social and educational response to the technological changes in the information age. This study also indicates that less powerful groups in the community and the educational field were able to put a body of low-status knowledge into the formal school curriculum. In order to analyze the process from social movement to subject formation, a theoretical framework is put forward identifying strong justification, effective lobbying, proper positioning and unofficial support for curriculum-building as the four key elements for legitimating a new social curriculum. Instead of justifying media education in terms of utilitarian and academic values, the advocates emphasized the pragmatic solution provided by the new curriculum to social problems. The manipulation of public support by creating a "climate of opinion" was vital to the success of lobbying. "Subject inhabitancy" was an effective way to find a curricular niche for a new social curriculum. Finally, the advocates' support for the curriculum development and implementation played an important role in strengthening the government's confidence in mandating a new program.

description: Families of center-based clustering methods are capable of handling high dimensional sparse data arising in Text Mining applications. All current center-based algorithms seek to minimize a particular objective function with an attempt to improve upon the standard k-means algorithm. This dissertation links traditional partition based approach to k-means with optimization treatment of the clustering problem. The interplay between two approaches sheds light on solutions generated by optimization techniques. We investigate the Hessian of the objective function, i.e, the second order optimality condition. When an algorithm leads to a critical point where the Hessian fails to be positive definite, we propose a way to move away from the critical point. Such a move may lead to possible improvement. In many cases additional information about the desired type of clusters is available. When incorporated into the clustering process this information may lead to better clustering results. We consider pairwise constrained clustering. In pairwise constrained clustering, we may have information about pairs of vectors that may not belong to the same cluster (cannot-links), information about pairs of vectors that must belong to the same cluster (must-links), or both. We focus on two k-means type clustering algorithms and two different distance--like functions. The clustering algorithms are k-means and spherical k-means. The distance-like functions are reverse Bregman divergence and cosine similarity. We show that for these algorithms and distance-like functions the pairwise constrained clustering problem can be reduced to clustering with cannot-link constraints only. We substitute cannot-link constraints by penalty, and propose clustering algorithms that tackle clustering with penalties.

description: The hypothesis that one or more biodiversity drops in the Phanerozoic eon, evident in the geological record, might have been caused by the most powerful kind of stellar explosion so far known Gamma Ray Bursts (GRB) has been discussed in several works. These stellar explosions could have left an imprint in the biological evolution on Earth and in other habitable planets. In this work we calculate the short-term lethality that a GRB would produce in the aquatic primary producers on Earth. This effect on life appears because of ultraviolet (UV) retransmission in the atmosphere of a fraction of the gamma energy, resulting in an intense UV flash capable of penetrating tens of meters in the water column in the ocean. We focus on the action of the UV flash on phytoplankton, as they are the main contributors to global aquatic primary productivity. Our results suggest that the UV flash could cause a significant reduction of phytoplankton biomass in the upper mixed layer of the World Ocean.

CAN PAP AND PSA BE USED AS PROGNOSTIC MARKERS FOR PROSTATE CANCER?
Creators: name: Nguyen, Vu Dinh
Publisher: name: Maryland Shared Open Access Repository
Year: 2010

description: Scientists have always searched for the ideal biomarker for prostate cancer. In the past, the detection and testing of prostate cancer have mainly depended on PAP. Currently, PSA is the diagnostic marker for the detection and testing of prostate cancer. The study will be using data obtained from the SEER program to analyze the prognosis ability for PAP and PSA. Using survival analysis techniques and combining them with propensity scores, models are constructed to determine the association between PAP and PSA with survival time. In their respective univariate analysis, positive PAP and positive PSA are associated with survival time. However, in the multivariate analysis controlling for factors (such as age, size of tumor, race, marital status, and stage of disease), positive PAP, not done PAP, unknown PAP, borderline PSA, and not done PSA are associated with survival time. And in the combination of propensity score and survival analysis techniques, both markers were not found to be associated with survival time. Thus, it seems that PSA and PAP cannot be use as markers for the prognosis of prostate cancer.
Browder's Non-Ejective Fixed Point Theorem and a Generalization

description: We prove and then generalize Felix Browder's non-ejective fixed point theorem. This is done in several steps. First, following Browder, a rather intricate approxima- tion argument is used to prove that every continuous function from the Hilbert cube into itself has a non-repulsive fixed point. This requires a some background material from topology, which is discussed in the Appendix; we also prove the Lefschetz fixed point theorem, the homogeneity of the Hilbert cube, and the Alexandroff mapping theorem as intermediate steps in proving the existence of non-repulsive fixed points. Next, again following Browder, we prove the existence of a non-ejective fixed point for every self map of the Hilbert cube. Finally, it is shown that Browder's theorem is true when fixed points are replaced by invariant Z-sets with trivial shape. This is a new generalization of Browder's theorem.

description: Putative organisms on the Martian surface would be exposed to potentially high doses of ionizing radiation during strong solar X-ray flares. We extrapolate the observed flare frequency-energy release scaling relation to releases much larger than seen so far for the sun, an assumption supported by observations of flares on other solar- and subsolar-mass main sequence stars. We calculate the surficial reprocessed X-ray spectra using a Monte Carlo code we have developed. Biological doses from indirect genome damage are calculated for each parameterized flare spectrum by integration over the X-ray opacity of water. We estimate the mean waiting time for solar flares producing a given biological dose of ionizing radiation on Mars and compare with lethal dose data for a wide range of terrestrial organisms. These timescales range from decades for significant human health risk to 0.5 Myr for D. radiodurans lethality. Such doses require total flare energies of 10^33--10^38 erg, the lower range of which has been observed for other stars. Flares are intermittent bursts, so acute lethality will only occur on the sunward hemisphere during a sufficiently energetic flare, unlike low-dose-rate, extended damage by cosmic rays. We estimate the soil and CO_2 ice columns required to provide 1/e shielding as 4--9 g cm^-2, depending on flare mean energy and atmospheric column density. Topographic altitude variations give a factor of two variation in dose for a given flare. Life in ice layers that may exist ~ 100 g cm^-2 below the surface would be well protected.

description: We present an automated method to track and identify neurons in C. elegans, called "fast Deep Learning Correspondence" or fDLC, based on the transformer network architecture. The model is trained once on empirically derived synthetic data and then predicts neural correspondence across held-out real animals via transfer learning. The same pre-trained model both tracks neurons across time and identifies corresponding neurons across individuals. Performance is evaluated against hand-annotated datasets, including NeuroPAL [1]. Using only position information, the method achieves 80.0% accuracy at tracking neurons within an individual and 65.8% accuracy at identifying neurons across individuals. Accuracy is even higher on a published dataset [2]. Accuracy reaches 76.5% when using color information from NeuroPAL. Unlike previous methods, fDLC does not require straightening or transforming the animal into a canonical coordinate system. The method is fast and predicts correspondence in 10 ms making it suitable for future real-time applications.

Im Sinne einer durchgängigen Sprachbildung ist auch der Regelunterricht Deutsch Teil des Zahnradgefüges einer Sprachbildung in allen Fächern, die sich unter anderem an den Ausgangslagen der jeweiligen Schüler*innengruppen zu orientieren hat. Mithilfe von Gruppendiskussionen werden im Beitrag mittels dokumentarischer Methode Orientierungen zu schüler*innenseitiger sprachlicher Heterogenität von gymnasialen Deutschlehrkräften herausgearbeitet. Dabei zeigt der Analyseschritt der „Reflektierenden Interpretation“, dass der gymnasiale Schulraum bezüglich der Erstsprache Deutsch als homogen gewertet wird. Heterogenität wird vor allem leistungsbezogen verhandelt. Sprachkompetenz wird überwiegend normativ und als Ausschlusskriterium wahrgenommen, indem suffiziente Deutschkenntnisse als Voraussetzung für den Besuch des Gymnasiums markiert werden.
description: Language skills are considered a central predictor of educational success, both as a resource and as a prerequisite for social participation and inclusion. In the context of a consistent language education, also the regular curriculum German teaching that does not focus on second or foreign language learning is part of the interrelated framework of language education across all subjects, which also considers the different starting points of the respective groups of students. Through group discussions, orientations regarding language heterogeneity of students from the perspective of secondary school German teachers are identified using the documentary method. The step of reflective interpretation in the analysis reveals that the secondary school environment is perceived as homogeneous regarding German as the first language. Heterogeneity is predominantly discussed in terms of academic performance. Language competence is mostly perceived normatively and as an exclusion criterion, with sufficient German language skills being marked as a prerequisite for attending secondary school.

description: Client management forms part of a company's internal control environment. If management's honesty and competency are questionable, the audit evidence derived from its control system may also be questionable. The first study in this thesis consists of a survey that was administered to identify which factors auditors associate with the honesty and competency of client management. Factors associated with the honesty of client management are more likely to be associated with fraud risk, whereas factors associated with the competency of client management are more likely to be associated with error risk. In most cases, the auditors correctly identified the factors as being related to honesty vs competency. However, some of the fraud risk factors were classified as error risk factors. This will have impact on the scope of work of an audit. The second study is a behavioural experiment to examine the impact of client management behaviour on auditor's judgment. This is a 2 (initial honesty) x 2 (initial competency) x 2 (consistency of honesty) x 2 (consistency of competency) between-subjects design experiment. The survey in the first study serves as a means to determine what behaviours can best represent the operationalisations of honesty and competency in the experiment. The theories on impression formation particularly the category-diagnosticity theory underlie the manipulations of variables in the experiment. Both honesty and competency are tested simultaneously in the experiment. Previous studies have only examined honesty and competency in separate experiments. The findings for the experiment are not consistent for all audit assertions, and thus, there is not sufficient evidence to support the propositions in the category-diagnosticity theory. Thus, when both honesty and competency are being evaluated at the same time by auditors, their evaluation of one could have an impact on the other.

description: Robust model-fitting to spectroscopic transitions is a requirement across many fields of science. The corrected Akaike and Bayesian information criteria (AICc and BIC) are most frequently used to select the optimal number of fitting parameters. In general, AICc modelling is thought to overfit (too many model parameters) and BIC underfits. For spectroscopic modelling, both AICc and BIC lack in two important respects: (a) no penalty distinction is made according to line strength such that parameters of weak lines close to the detection threshold are treated with equal importance as strong lines and (b) no account is taken of the way in which spectral lines impact on narrow data regions. In this paper we introduce a new information criterion that addresses these shortcomings, the "Spectral Information Criterion" (SpIC). Spectral simulations are used to compare performances. The main findings are (i) SpIC clearly outperforms AICc for high signal to noise data, (ii) SpIC and AICc work equally well for lower signal to noise data, although SpIC achieves this with fewer parameters, and (iii) BIC does not perform well (for this application) and should be avoided. The new method should be of broader applicability (beyond spectroscopy), wherever different model parameters influence separated small ranges within a larger dataset and/or have widely varying sensitivities.

description: Change-point problems arise in a variety of practical situations including engineering and health science applications. There are generally two approaches for these problems. One is the likelihood approach, and the other is the Bayesian approach. The Bayes-type test statistics, which are derived as the marginal likelihood ratio with appropriate prior distributions on the nuisance parameters, have been shown to provide higher power than likelihood ratio tests in linear regression models and first order autoregressive models. The change-point problem in logistic models has not been investigated extensively. The aim of this thesis is to provide a unified approach of Bayes-type and Rao's Score test to the problem of testing for constancy of parameters in logistic regression models, and explore the connection between Bayes-type tests and Rao's Score tests. Test Statistics are derived for changes at unknown times in the parameters of a logistic regression model. Asymptotic distribution theory for the tests is discussed. Simulations are carried out to compare the power with other options from the literature. An application of the test procedure on a real data set has been discussed.

The structural analysis revealed that the crystal axes of the NiFe2O4 nanoparticles are aligned with those of the ferroelectric matrix. The composite has good ferroelectric and magnetic properties. We measured the transverse and longitudinal components of the magnetoelectric voltage coefficient, which supports the postulate that the magnetoelectric effect comes from direct stress coupling between magnetostrictive NiFe2O4 and piezoelectric Pb(Zr0.52Ti0.48)O3 grains.

description: We report the results of a 100 square degree survey of the Taurus Molecular Cloud region in the J = 1-0 transition of 12CO and 13CO. The image of the cloud in each velocity channel includes ~ 3 million Nyquist sampled pixels on a 20" grid. The high sensitivity and large linear dynamic range of the maps in both isotopologues reveal a very complex, highly structured cloud morphology. There are large scale correlated structures evident in 13CO emission having very fine dimensions, including filaments, cavities, and rings. The 12CO emission shows a quite different structure, with particularly complex interfaces between regions of greater and smaller column density defining the boundaries of the largest-scale cloud structures. The axes of the striations seen in the 12CO emission from relatively diffuse gas are aligned with the direction of the magnetic field. Using a column density-dependent model for the CO fractional abundance, we derive the mass of the region mapped to be 24,000 solar masses, a factor of three greater than would be obtained with canonical CO abundance restricted to the high column density regions. We determine that half the mass of the cloud is in regions having column density below 2.1x10^{21} per square cm. The distribution of young stars in the region covered is highly nonuniform, with the probability of finding a star in a pixel with a specified column density rising sharply for N(H2) = 6x10^{21} cm^{-2}. We determine a relatively low star formation efficiency (mass of young stars/mass of molecular gas), between 0.3 and 1.2 %, and an average star formation rate during the past 3 Myr of 8x10^{-5} stars yr^{-1}.

description: Blockchain technologies have been rapidly enhanced in recent years. However, its scalability still has limitations in terms of throughput and broadcast delay as the network and the amount of transaction data increase. To improve scalability of blockchain networks, we propose a novel approach named PiChu that accelerates block propagation in blockchain networks by pipelining and verifying chunks of a block in parallel. Accelerating block propagation reduces the mining interval and chance of fork occurring, which in turn increases throughput. Our approach can be applied to the blockchain networks either directly or with a minor modification to the consensus. Through an extensive and large scale simulations, we validate that the proposed PiChu scheme significantly enhances the scalability of blockchain networks. For instance, a 64 MB block can be broadcasted in just 80 seconds in a blockchain network with a million nodes. The efficiency of PiChu broadcasting increases with bigger block sizes and a larger number of nodes in the network.

description: We reinterpret neutron scattering and Raman spectroscopy experiments in La(2-x)Sr(x)CuO(4), showing modulation of spin and lattice degrees of freedom both in the low-temperature orthorhombic and tetragonal phases, in terms of a magneto-elastic coupling between noncollinear configurations for the copper spins and the oxygen octahedra. The magneto-elastic coupling furthermore explains the recently discovered magnetic-field induced untwinning in La(2-x)Sr(x)CuO(4), for x<2%, and allows us to understand why in La(2-x-y)Sr(x)Nd(y)CuO(4) with y=0.4 and x=1/8, for example, when (1,0) and/or (0,1) static spin spirals are stabilized due to hole frustration, the atomic modulation in the low-temperature tetragonal phase of La(2-x-y)Sr(x)Nd(y)CuO(4) has a periodicity of 4 lattice spacings, half the magnetic one.

description: General purpose quantum computers can, in principle, entangle a number of noisy physical qubits to realise composite qubits protected against errors. Architectures for measurement-based quantum computing intrinsically support error-protected qubits and are the most viable approach for constructing an all-photonic quantum computer. Here we propose and demonstrate an integrated silicon photonic architecture that both entangles multiple photons, and encodes multiple physical qubits on individual photons, to produce error-protected qubits. We realise reconfigurable graph states to compare several schemes with and without error-correction encodings and implement a range of quantum information processing tasks. We observe a success rate increase from 62.5% to 95.8% when running a phase estimation algorithm without and with error protection, respectively. Finally, we realise hypergraph states, which are a generalised class of resource states that offer protection against correlated errors. Our results show how quantum error-correction encodings can be implemented with resource-efficient photonic architectures to improve the performance of quantum algorithms.
Single electron spin and its coherence in Si quantum computer architecture

description: The possibility of performing single spin measurements in Si-based quantum computers through electric field control of electrons bound to double donors near a barrier interface is assessed. We find that both the required electric fields and the tunneling times involved are probably too large for practical implementations. On the other hand, operations with double donors in their first excited state require smaller fields and faster tunneling times, and are therefore suitable for spin-to-charge conversion measurements. We also propose a measurement scheme that would render statistical (ensemble) estimates of the spin coherence at the Si/SiO2 interface.

description: Clinical History: A 47-year-old male presented in ER with status epilepticus. One year before that, he began to suffer from recurrent headache and seizures. Twenty years ago, he had brain CT performed after one episode of seizure. It revealed multiple calcifications and anthelmintic treatment was administered for suspected neurocysticercosis. He remained seizure-free until last year. From then on, albendazole and praziquantel were readministered but to no avail. Prednisone 20 mg daily reduced the frequency of seizures. However, when prednisone stopped, seizures rebounded.

description: Two-dimensional van der Waals compounds with magnetic ions on a honeycomb lattice are hosts to a variety of exotic behavior. The magnetic interactions in one such compound, MnPSe$_3$, are investigated with elastic and inelastic neutron scattering. Magnetic excitations are observed in the magnetically ordered regime and persist to temperatures well above the ordering temperature, $\rm T_N$ = 74 K, consistent with low dimensional magnetic interactions. The inelastic neutron scattering results allow a model spin Hamiltonian to be presented that includes dominant intralayer interactions of $J_{1ab}$=0.45 meV, $J_{2ab}$=0.03 meV, $J_{3ab}$=0.19 meV, and appreciable interlayer interactions of $J_c$=0.031(5) meV. No evidence for anisotropy in the form of a spin-gap is observed in the data collected. The measurements on MnPSe$_3$ are contrasted with those on MnPS$_3$ and reveal a large increase in the interlayer exchange interactions in MnPSe$_3$, despite the quasi-2D magnetic behavior.

description: Clinical History: We retrospectively evaluated the imaging findings of young patients (below 50 years of age) affected by COVID-19 infection.

Six patients in the 27-46 age range were admitted to the Emergency Room (ER) of our institution in the first half of March 2020 with the main complaint of fever (5/6) and/or cough (5/6), and with unremarkable clinical history. The results of laboratory tests were in range, except for respiratory alkalosis (3/6) and reduced leukocyte count (1/6). Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR) for the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) was found positive on nasopharyngeal swab (5/6) or bronchoalveolar lavage (1/6). None of the patients required intubation; only 3 of them required respiratory support with low flow oxygen supplementation through nasal cannula (2/6), or CPAP (1/6).
