description: We have analyzed the double-lined eclipsing binary system OGLE-051019.64-685812.3 in the LMC which consists of two G4 giant components with very similar effective temperatures. A detailed analysis of the OGLE I-band light curve of the system, radial velocity curves for both components derived from high-resolution spectra, and near-infrared magnitudes of the binary system measured outside the eclipses has allowed us to obtain an accurate orbit solution for this eclipsing binary, and its fundamental physical parameters. Using a surface brightness-(V-K) color relation for giant stars we have calculated the distance to the system and obtain a true distance modulus of 18.50 mag, with an estimated total uncertainty of ~ 3 %. More similar eclipsing binary systems in the LMC which we have discovered and for which we are currently obtaining the relevant data will allow us to better check on the systematics of the method and eventually provide a distance determination to the LMC accurate to 1 percent, so much needed for the calibration of the distance scale.

description: The aim of this paper is to study integer rounding properties of various systems of linear inequalities to gain insight about the algebraic properties of Rees algebras of monomial ideals and monomial subrings. We study the normality and Gorenstein property--as well as the canonical module and the a-invariant--of Rees algebras and subrings arising from systems with the integer rounding property. We relate the algebraic properties of Rees algebras and monomial subrings with integer rounding properties and present a duality theorem.

description: We discuss the rest-frame UV emission between 5< z < 7 from the MareNostrum High-z Universe, a SPH simulation done with more than 2 billion particles. Cosmological simulations of galaxy formation generally overpredict the UV restframe luminosity function at high redshift, both at the bright and faint ends. In this Letter we explore a dust attenuation model where a larger extinction is applied to star populations younger than a given age, mimicking the effect of a clumpy interstellar medium. We show that this scenario fits reasonably well both the UV luminosity functions and the UV-continuum slopes derived from observations. The model assumes a large obscuration for stars younger than 25 Myr from the gas clouds where they should be embedded at their formation time. We find that the optical depth in these clouds should be between 30 and 100 times larger than the mean optical depth for the homogeneous part of the interstellar medium. These values are one order of magnitude larger than those estimated in local galaxies. Therefore, we conclude that LambdaCDM predictions for the high-z UV emission can accommodate the current observations if we consider a dust extinction model based on the assumption of a clumpy environment at high redshift.

A case control study of occupational exposures and the risk of prostate cancer
Creators: name: Doolan, Glenn William

Subjects: Uncategorized

description: BACKGROUND The purpose of this research project was to investigate the occupational exposures of participants in a case control study of prostate cancer. By age 60 years over 50% of men will have cancerous lesions in their prostate. It has been suggested that at age 115 years, all men would have prostate cancer. Although most men will develop some form of prostate cancer only a small proportion die from it. The important determination by doctors with their patients is to identify which prostate cancers are low to moderate grade and can be treated or ignored and which are high grade and need to be removed immediately to prolong life. DATA COLLECTION AND ANALYSIS The occupational literature suggests and supports the contention that certain agents in the workplace are associated with increased risk of prostate cancer but these observations require further corroboration. Data on self-reported occupational histories were available from an Australian case control study conducted between 1994 and 1998. The data were analysed using the Finnish Job Exposure Matrix (FINJEM). The researcher coded the occupational work histories for each of the 1,436 cases and 1,349 controls that were frequency matched on age to each to the cases, and examined the level of exposure of occupational groups to the risk and severity of prostate cancer. The level of exposure of the occupational groups in relation to the prostate cancer risk was examined for 23 variables related to chemical, ergonomic factors, physical agents and psychological barriers as well as two calculated variables of Activity-over-time and Duration of occupational exposure. There were two research questions: 1) is there an association between occupational exposures and risk of prostate cancer and 2) if so, is there a difference in risk between moderate grade tumours and high grade tumours? RESULTS The occupational exposure data were analysed as tertiles and/or quartiles using logistic regression. Analysis of differences between moderate grade and high grade tumours was done by polytomous logistic regression. Few significant associations were found; the exceptions were with physical workload, workload and duration. A weak relationship was found with ionizing radiation. Overall, the findings of this study indicate that few occupational exposures are related to prostate cancer.

description: Using a recently developed formalism, we present an in-depth analysis of how the thermodynamics of the climate system varies with CO2 concentration by performing experiments with a simplified yet Earth-like climate model. We find that, in addition to the globally averaged surface temperature, the intensity of the Lorenz energy cycle, the Carnot efficiency, the entropy production and the degree of irreversibility of the system are linear with the logarithm of the CO2 concentration. The generalized sensitivities proposed here suggest that the climate system becomes less efficient, more irreversible, and features higher entropy production as it becomes warmer.

Neural networks in application to dolphin whistle detection and generation
Creators: name: Lu, Xi
Publisher: name: University of British Columbia
Year: 2024

description: In the underwater realm, marine mammals rely heavily on acoustic signals for their communications. Being able to accurately and easily detect these signals can aid in studying factors such as creature presence and migratory habits. Additionally, recent research in the field of covert Underwater Acoustic Communications (UWAC) has begun to incorporate marine mammal signals to utilise naturally-occurring sounds. Compared to traditional methods, marine mammal signals allow transmissions to occur at higher power levels, increasing the range of covert communications. Commonly, there are two categories of acoustic marine mammal signals: clicks and whistles. Both can be detected by converting audio waveforms to spectrogram images, and the detection process is often done visually by human experts. This image data type is particularly important for whistle detection, as these tend to be lower power and have a narrow-band, time-varying frequency profile. Given the potential uses of these signals, the creation of accurate, consistent automated detection methods has been an active area of research. This thesis investigates the utility of Neural Networks (NNS) in application to dolphin whistle detection and generation. We seek to provide a detection pipeline which is robust to changing environments and requires no context-specific work to be done. This is accomplished by performing minimal preprocessing on data and utilising transfer learning from a large dataset into a newer, smaller one. Using these techniques, we are able to achieve detection accuracy greater than 95% for our tested models. For whistle generation, we investigate two methods known as Generative Adversarial Networks (GANS) and Denoising Diffusion Probabilistic Models (DDPMS), the latter of which is found to be more effective. We separate the task of generating synthetic realistic whistles into two steps: contour and variations. The end result is a cascaded DDPM system which generates whistles following these two steps. We demonstrate an iterative detection application to assess the efficacy of this generative method, integrating our synthetic samples into the task of improving automated signal detection.

He II absorption and the sawtooth spectrum of the cosmic far-UV background

Year: 2008

description: Cosmic ultraviolet background radiation between 3 and 4 Ryd is reprocessed by resonant line absorption in the Lyman series of intergalactic He II. This process results in a sawtooth modulation of the radiation spectrum from the He II Lya frequency to the Lyman limit. The size of this modulation is a sensitive probe of the epoch of helium reionization and of the sources that keep the intergalactic medium (IGM) highly ionized. For large absorption opacities, the background intensity will peak at frequencies just above each resonance, go to zero at resonance, and fluctuate greatly just below resonance. The He II sawtooth modulation may be one of the missing ingredients needed in the modelling of the abundances of metal ions like C III and Si IV observed in the IGM at redshift 3.

We argue that, in contrast to their six-dimensional cousins, the two problems are related but not identical. We develop a vertex formalism for the crystal partition function, which calculates a generating function for the dimension 0 and 1 subschemes of the toric surface, and describe the modifications required to obtain the corresponding gauge theory partition function.

Simulation-based inference of micelle geometry from 2D cryo-EM images of membrane proteins
Creators: name: De Castro Alvarenga, Helena
Publisher: name: University of British Columbia
Year: 2024

description: Membrane proteins are important pharmaceutical targets, but the intrinsic hydrophobic nature of their transmembrane domains imposes a challenge for experimental structural studies. The inclusion of membrane-mimetic detergents in the extraction stabilizes the protein but adds a new factor to consider in structural experiments. Although cryo-EM is a revolutionizing tool, there is still a lack of methods to properly disentangle the contribution of the protein from the detergent micelle to the generated images. In this work, we review the properties and availabilities of micelles images from cryo-EM studies of membrane proteins and outline the development of an in-silico model of the protein-detergent system and a pipeline for inferring geometric parameters of micelles from cryo-EM simulated images. Since our inference method relies on the Approximation Bayesian Computation (ABC) algorithm, we tested different scoring metrics and ran the method on simulated images from existing structures. As our inferring algorithm yields a distribution of micelle parameters that approximates well the ground truth value in our experiments, we obtain a proof-of-concept that will need more refinements to get applied to experimental data but also hold some promising applications for automating and improving cryo-EM imaging of membrane proteins.

description: A population of very light primordial black holes which evaporate before nucleosynthesis begins is unconstrained unless the decaying black holes leave stable relics. We show that gravitons Hawking radiated from these black holes would source a substantial stochastic background of high frequency gravititational waves ($10^{12}$ Hz or more) in the present universe. These black holes may lead to a transient period of matter dominated expansion. In this case the primordial universe could be temporarily dominated by large clusters of "Hawking stars" and the resulting gravitational wave spectrum is independent of the initial number density of primordial black holes.

Phylodynamic pattern and genetic characterization of human influenza A/H3N2 virus in Indonesia from 2008 to 2010
Creators: name: Agustiningsih
Publisher: name: Monash University
Year: 2017

description: Influenza viruses are by nature unstable with high levels of mutations. The sequential accumulation of mutations in the surface glycoproteins allows the virus to evade the neutralizing antibodies. The year-round circulation of H3N2 viruses and the endemicity of H5N1 virus in Indonesia are of serious concern, because the two viruses may reeassort to generate strains with pandemic potential. The consideration of the tropics as the influenza reservoir where viral genetic and antigenic diversity are continually generated and reintroduced into temperate countries makes the study of influenza virus evolution in Indonesia is essential. As only limited data are available, there is an urgent need to monitor the phylodynamic and evolutionary patterns, and the genetic characteristics of the influenza A/H3N2 virus in Indonesia. It is also necessary to evaluate how mutations in hemagglutinin (HA) gene might impact on influenza vaccine efficacy. The present study describes the evolutionary and molecular analyses of HA and neuraminidase (NA) genes and their corresponding encoded proteins of influenza A/H3N2 virus from 2008 to 2010 in Indonesia. It aims to provide insight into the evolutionary pattern and the genetic characteristics of the surface glycoprotein of human influenza A/H3N2 virus in Indonesia, from 2008 to 2010. A total of 100 full-length sequences of HA and NA genes of H3N2 virus were obtained from archived samples of Influenza-Like Illness (ILI) surveillance collected from 2008 to 2010. Phylogenetic and evolutionary analyses showed the dynamics of IndonesianH3N2 virus from 2008 to 2010. Obvious antigenic drift with typical ‘ladder-like’ phylogeny was observed. Multiple lineages were also found in each year, suggesting co-circulation of H3N2 strains at different time periods. The mutations of the Indonesian H3N2 virus were not geographically related. This study confirms that the Indonesian samples had high levels of relative genetic diversity and nucleotide substitution rate. It was also revealed that H3N2 virus had circulated approximately one year before the sampling dates. Major mutations at the antigenic sites A and B of HA protein were identified, while relatively conserved sequences were found at the catalytic sites of NA protein. The mutations at the HA antigenic sites appeared to have influence on the predicted value of vaccine efficacy that emphasizes the need of annual vaccine reformulation based on the circulating viral strain in the corresponding year.
Surprisingly Weak Magnetism on Young Accreting Brown Dwarfs

description: We have measured the surface magnetic flux on four accreting young brown dwarfs and one non-accreting young very low-mass star utilizing high resolution spectra of absorption lines of the FeH molecule. A magnetic field of 1-2 kG had been proposed for one of the brown dwarfs, 2MASS J1207334$-$393254, because of its similarities to higher mass T Tauri stars as manifested in accretion and the presence of a jet. We do not find clear evidence for a kilo-Gauss field in any of our young brown dwarfs but do find a 2 kG field on the young VLM star. Our 3-$σ$ upper limit for the magnetic flux in 2MASS J1207334$-$393254 just reaches 1 kG. We estimate the magnetic field required for accretion in young brown dwarfs given the observed rotations, and find that fields of only a few hundred Gauss are sufficient for magnetospheric accretion. This predicted value is less than our observed upper limit. We conclude that magnetic fields in young brown dwarfs are a factor of five or more lower than in young stars of about one solar mass, and in older stars with spectral types similar to our young brown dwarfs. It is interesting that, during the first few million years, the fields scale down with mass in line with what is needed for magnetospheric accretion, yet no such scaling is observed at later ages within the same effective temperature range. This scaling is opposite to the trend in rotation, with shorter rotation periods for very young accreting brown dwarfs compared with accreting solar-mass objects (and very low Rossby numbers in all cases). We speculate that in young objects a deeper intrinsic connection may exist between magnetospheric accretion and magnetic field strength, or that magnetic field generation in brown dwarfs may be less efficient than in stars. Neither of these currently have an easy physical explanation.

description: Welche besondere Sorgfalt bei der redaktionellen Verwendung von historischen Fotos nötig ist, konnte man zuletzt im Kontext des 90. Jahrestages des Reichstagsbrandes im Februar 2023 beobachten. In vielen Tageszeitungen, Dokumentationen oder Fernsehberichten wurde an das Ereignis erinnert, denn bis heute sind die Hintergründe der Brandstiftung umstritten. Wenn über ein solches historisches Ereignis und dessen Deutung berichtet wird, stellt sich in vielen Zeitungs- und Online-Redaktionen zwangsläufig die Frage nach der Bebilderung. Im Kontext des Reichstagsbrandes kommt es dabei häufig zu ungenauen oder falschen Darstellungen, da es nur sehr wenige Aufnahmen gibt, die tatsächlich am Abend des 27. Februars 1933 entstanden sind und den brennenden Reichstag zeigen. In den einschlägigen Bildagenturen werden darüber hinaus aber auch vermeintlich „echte“ Fotos vertrieben, die einer genauen Überprüfung bedürfen.

description: User satisfaction plays a crucial role in user experience (UX) evaluation. Traditionally, UX measurements are based on subjective scales, such as questionnaires. However, these evaluations may suffer from subjective bias. In this paper, we explore the acoustic and prosodic features of speech to differentiate between positive and neutral UX during interactive sessions. By analyzing speech features such as root-mean-square (RMS), zero-crossing rate(ZCR), jitter, and shimmer, we identified significant differences between the positive and neutral user groups. In addition, social speech features such as activity and engagement also show notable variations between these groups. Our findings underscore the potential of speech analysis as an objective and reliable tool for UX measurement, contributing to more robust and bias-resistant evaluation methodologies. This work offers a novel approach to integrating speech features into UX evaluation and opens avenues for further research in HCI.

description: The enhancement of the sub-barrier fusion cross sections was explained as the lowering of the dynamical fusion barriers within the framework of the improved isospin-dependent quantum molecular dynamics (ImIQMD) model. The numbers of nucleon transfer in the neck region are appreciably dependent on the incident energies, but strongly on the reaction systems. A comparison of the neck dynamics is performed for the symmetric reactions $^{58}$Ni+$^{58}$Ni and $^{64}$Ni+$^{64}$Ni at energies in the vicinity of the Coulomb barrier. An increase of the ratios of neutron to proton in the neck region at initial collision stage is observed and obvious for neutron-rich systems, which can reduce the interaction potential of two colliding nuclei. The distribution of the dynamical fusion barriers and the fusion excitation functions are calculated and compared them with the available experimental data.

description: The spreading of a bilayer gold film propagating outward from gold clusters, which are pinned to clean Si(111), is imaged in real time by low energy electron microscopy. By monitoring the evolution of the boundary of the gold film at fixed temperature, a linear dependence of the spreading radius on time is found. The measured spreading velocities in the temperature range of 800 < T < 930 K varied from below 100 pm/s to 50 nm/s. We show that the spreading rate is limited by the reaction to form Au silicide, and the spreading velocity is likely regulated by the reconstruction of the gold silicide that occurs at the interface.

description: The well-established correlations between the mass of massive black holes (BHs) in the nuclei of most studied galaxies and various global properties of their hosting galaxy lend support to the idea that dwarf galaxies and globular clusters could also host a BH in their centers. Direct kinematic detection of BHs in dwarf spheroidal (dSph) galaxies are seriously hindered by the small number of stars inside the gravitational influence region of the BH. The aim of this Letter is to establish an upper dynamical limit on the mass of the putative BH in the Ursa Minor (UMi) dSph galaxy. We present direct N-body simulations of the tidal disruption of the dynamical fossil observed in UMi, with and without a massive BH. We find that the observed substructure is incompatible with the presence of a massive BH of (2-3)x10^4 Msun within the core of UMi. These limits are consistent with the extrapolation of the M_{BH}-sigma relation to the M_{BH}<10^6 Msun regime. We also show that the BH may be off-center with respect to the center of symmetry of the whole galaxy.

Wavefunction parameterizations using the atomic cluster expansion

Publisher: name: University of British Columbia

description: In recent decades, Ab initio quantum chemistry methods have played a crucial role in elucidating the electronic structures of molecules and materials. Despite their widespread application, the constant emergence of new methods lacking rigorous mathematical foundations raises concerns about their reliability. This thesis seeks to bridge this gap by addressing the electronic structure problem through a mathematical lens, leveraging existing numerical analysis results to address the electronic structure problem. Focusing on wavefunction methods, specifically Variational Monte Carlo, our investigation delves into the distinctive features of the Schrodinger equation across different chemical systems, encompassing variations between molecules and materials. We conduct a numerical analysis to derive the convergence of the Ewald Summation of the simulated potential. Subsequently, we employ the Atomic Cluster Expansion to parameterize the trial wavefunction, demonstrating its adaptability to different chemical systems. Building upon existing numerical analyses of the Atomic Cluster Expansion, we argue that our methodology not only provides superior parameterization flexibility compared to existing methods but also ensures a systematic and mathematically sound process for deriving the parameterizations. Finally, we implement simulations to assess the effectiveness of our proposed wavefunction architectures in the 1D uniform electron gas, a system allowing us to probe electronic correlation effects.

description: MWC 778 is an unusual and little-studied young stellar object located in the IC 2144 nebula. Recent spectroscopy by Herbig and Vacca (2008) suggested the presence of an edge-on circumstellar disk around it. We present near-infrared adaptive optics imaging polarimetry and mid-infrared imaging which directly confirm the suspected nearly-edge-on disk around MWC 778 (i ~ 70-80 degrees) plus reveal a more extensive envelope pierced by bipolar outflow cavities. In addition, our mid-infrared images and near-infrared polarization maps detect a spiral-shaped structure surrounding MWC 778, with arms that extend beyond 6" on either side of the star. Although MWC 778 has previously been classified as an Herbig Ae/Be star, the properties of its central source (including its spectral type) remain fairly uncertain. Herbig & Vacca (2008) suggested an F or G spectral type based on the presence of metallic absorption lines in the optical spectrum, which implies that MWC 778 may belong to the fairly rare class of Intermediate-Mass T Tauri Stars (IMTTSs) which are the evolutionary precursors to Herbig Ae/Be objects. Yet its integrated bolometric luminosity, > 750 L_sun (for an assumed distance of 1 kpc) is surprisingly high for an F or G spectral type, even for an IMTTS. We speculate on several possible explanations for this discrepancy, including its true distance being much closer than 1 kpc, the presence of a binary companion, and/or a non-stellar origin for the observed absorption lines.

description: Massive young stellar objects (YSOs), like low-mass YSOs, appear to be surrounded by optically thick envelopes and/or disks and have regions, often bipolar, that are seen in polarized scattered light at near-infrared wavelengths. We are using the 0.2'' spatial resolution of NICMOS on Hubble Space Telescope to examine the structure of the disks and outflow regions of massive YSOs in star-forming regions within a few kpc of the Sun. Here we report on 2 micron polarimetry of NGC 6334 V and S255 IRS1. NGC 6334 V consists of a double-lobed bright reflection nebula seen against a dark region, probably an optically thick molecular cloud. Our polarization measurements show that the illuminating star lies ~ 2'' south of the line connecting the two lobes; we do not detect this star at 2 micron, but there are a small radio source and a mid-infrared source at this location. S255 IRS1 consists of two YSOs (NIRS1 and NIRS3) with overlapping scattered light lobes and luminosities corresponding to early B stars. Included in IRS1 is a cluster of stars from whose polarization we determine the local magnetic field direction. Neither YSO has its scattered light lobes aligned with this magnetic field. The line connecting the scattered light lobes of NIRS1 is twisted symmetrically around the star; the best explanation is that the star is part of a close binary and the outflow axis of NIRS1 is precessing as a result of non-coplanar disk and orbit. The star NIRS3 is also offset from the line connecting its two scattered light lobes. We suggest that all three YSOs show evidence of episodic ejection of material as they accrete from dense, optically thick envelopes.

description: Consider Bernoulli(1/2) percolation on $\mathbb{Z}^d$, and define a perfect matching between open and closed vertices in a way that is a deterministic equivariant function of the configuration. We want to find such matching rules that make the probability that the pair of the origin is at distance greater than $r$ decay as fast as possible. For two dimensions, we give a matching of decay $cr^{1/2}$, which is optimal. For dimension at least 3 we give a matching rule that has an exponential tail. This substantially improves previous bounds. The construction has two major parts: first we define a sequence of coarser and coarser partitions of $\mathbb{Z}^d$ in an equivariant way, such that with high probability the cell of a fixed point is like a cube, and the labels in it are i.i.d. Then we define a matching for a fixed finite cell, which stabilizes as we repeatedly apply it for the cells of the consecutive partitions. Our methods also work in the case when one wants to match points of two Poisson processes, and they may be applied to allocation questions.

description: In times of dynamically changing markets, companies are forced to (re)design their processes quickly and frequently, which typically implies a significant degree of time-consuming and cost-intensive manual work. To alleviate this drawback, we envision the automated planning of process models. More precisely, we propose a novel algorithm for an automated construction of the control flow pattern ‘exclusive choice’, which constitutes an essential step toward an automated planning of process models. The algorithm is built upon an abstract representation language that provides a general and formal basis and serves as the vocabulary to define the planning problem. As part of our evaluation, we find that, based on a given planning problem, our algorithm is not subject to potential modeling failures. We further implement the approach in process planning software and analyze not only its feasibility and applicability by means of several real-world processes from different application contexts and companies but also its practical utility based on the criteria flexibility by definition, modeling costs, and modeling time.

description: By means of numerical simulations we investigate the geometric properties of loops on hypercubic lattice graphs in dimensions d=2 through 7, where edge weights are drawn from a distribution that allows for positive and negative weights. We are interested in the appearance of system-spanning loops of total negative weight. The resulting negative-weight percolation (NWP) problem is fundamentally different from conventional percolation, as we have seen in previous studies of this model for the 2d case. Here, we characterize the transition for hypercubic systems, where the aim of the present study is to get a grip on the upper critical dimension d_u of the NWP problem. For the numerical simulations we employ a mapping of the NWP model to a combinatorial optimization problem that can be solved exactly by using sophisticated matching algorithms. We characterize the loops via observables similar to those in percolation theory and perform finite-size scaling analyses, e.g. 3d hypercubic systems with side length up to L=56 sites, in order to estimate the critical properties of the NWP phenomenon. We find our numerical results consistent with an upper critical dimension d_u=6 for the NWP problem.

NICMOS Photometry of the Unusual Dwarf Planet Haumea and its Satellites

description: We present here HST NICMOS F110W and F160W observations of Haumea, and its two satellites Hi'iaka and Namaka. From the measured (F110W-F160W) colours of -1.209 +/-0.004, -1.48 +/- 0.06, and -1.4 +/- 0.2 mag for each object, respectively, we infer that the 1.6 imcron water-ice absorption feature depths on Hi'iaka and Namaka are at least as deep as that of Haumea. The light-curve of Haumea is detected in both filters, and we find that the infrared colour is bluer by approximately 2-3% at the phase of the red spot. These observations suggest that the satellites of Haumea were formed from the collision that produced the Haumea collisional family.

description: In this paper we study a curvaton model obtained by considering a probe anti-D3-brane with angular motion at the bottom of a KS throat with approximate isometries. We calculate the spectrum of curvature perturbations and the non-Gaussianities of this model. Specifically, we consider the limit of relativistic rotation of the curvaton brane which leads to a small sound speed, and thus it can be viewed as an implementation of the DBI-curvaton mechanism. We find that the primordial power spectrum is nearly scale-invariant while the non-Gaussianity of local type is sizable and that of equilateral type is usually large and negative. Moreover, we study both the theoretical and observational constraints on this model, and find that there exists a sizable allowed region for the phase space of this model.
