Interannual and interdecadal patterns in timing and abundance of phytoplankton and zooplankton in the central straight of Georgia, BC with special reference to Neocalanus Plumchrus
Creators: name: Bornhold, Elizabeth Anne
Publisher: name: University of British Columbia
Year: 2009

description: Aspects of the biological oceanography of the Strait of Georgia have been studied periodically since the 1930s, although very few studies have measured nutrient concentrations, the timing and magnitude of the spring phytoplankton bloom, and the timing and magnitude of the spring zooplankton peak biomass. This thesis reports nutrient concentrations and phytoplankton and zooplankton biomass during spring of 1996-1998 in the central Strait of Georgia. Sampling was conducted biweekly from February to June, for nitrate, phosphate, ammonium, and urea concentrations, chlorophyll concentrations, zooplankton dry weight, and Neocalanus plumchrus stage composition. Nitrate and phosphate concentrations were high in late winter but began to decline in late March reaching a minimum in June. Ammonium and urea concentrations were low in late winter and increased in late March reaching a maximum in April. Concentrations then declined and reached a minimum in June. Two large chlorophyll peaks were observed in the Strait in March and June, bracketing the large peak in zooplankton biomass that occurred in late April. These results were then compared with results from previous studies in an effort to determine i f the timing and the magnitude of spring bloom are controlling the timing and magnitude of the zooplankton peak biomass. Since the mid-1960s there have been nine years where sampling took place in the spring for both chlorophyll and zooplankton biomass. These data revealed in years when there was tight coupling between phytoplankton and zooplankton, zooplankton biomass was not always greater than years with poor coupling. This suggests that this relationship is more complex and that there are other factors that determine the magnitude of the spring peak in zooplankton biomass. The observed peak in zooplankton biomass in the 1990s occurred approximately one month earlier than had previously been reported for the Strait in the 1960s and 1970s. Because N. plumchrus is the dominant zooplankton species in these waters at this time, it was proposed that this shift in timing was due to a change in the developmental timing of this copepod. When historical N. plumchrus stage composition data were collected it was determined that there has been a shift in developmental timing on the order of 25 days. Three hypotheses were proposed to explain this change. Presently, the favoured hypothesis is that a gradual warming o f the surface layer in the Strait over the past 30 years has induced this change, possibly due to a shortening of each copepodite developmental stage.

description: We present a novel, hardware-agnostic implementation strategy for lattice Boltzmann (LB) simulations, which yields massive performance on homogeneous and heterogeneous many-core platforms. Based solely on C++17 Parallel Algorithms, our approach does not rely on any language extensions, external libraries, vendor-specific code annotations, or pre-compilation steps. Thanks in particular to a recently proposed GPU back-end to C++17 Parallel Algorithms, it is shown that a single code can compile and reach state-of-the-art performance on both many-core CPU and GPU environments for the solution of a given non trivial fluid dynamics problem. The proposed strategy is tested with six different, commonly used implementation schemes to test the performance impact of memory access patterns on different platforms. Nine different LB collision models are included in the tests and exhibit good performance, demonstrating the versatility of our parallel approach. This work shows that it is less than ever necessary to draw a distinction between research and production software, as a concise and generic LB implementation yields performances comparable to those achievable in a hardware specific programming language. The results also highlight the gains of performance achieved by modern many-core CPUs and their apparent capability to narrow the gap with the traditionally massively faster GPU platforms. All code is made available to the community in form of the open-source project "stlbm", which serves both as a stand-alone simulation software and as a collection of reusable patterns for the acceleration of pre-existing LB codes.

description: Several alternative approaches to quantum gravity problem suggest the modification of the {\it fundamental volume $ω_{0}$} of the accessible phase space for representative points. This modified fundamental volume has a novel momentum dependence. In this paper, we study the effects of this modification on the thermodynamics of an ideal gas within the microcanonical ensemble and using the generalized uncertainty principle(GUP). Although the induced modifications are important only in quantum gravity era, possible experimental manifestation of these effects may provides strong support for underlying quantum gravity proposal.

description: Recently the problem of Unambiguous State Discrimination (USD) of mixed quantum states has attracted much attention. So far, bounds on the optimum success probability have been derived [1]. For two mixed states they are given in terms of the fidelity. Here we give tighter bounds as well as necessary and sufficient conditions for two mixed states to reach these bounds. Moreover we construct the corresponding optimal measurement strategies. With this result, we provide analytical solutions for unambiguous discrimination of a class of generic mixed states. This goes beyond known results which are all reducible to some pure state case. Additionally, we show that examples exist where the bounds cannot be reached.

description: Significant strides have been made in creating voice identity representations using speech data. However, the same level of progress has not been achieved for singing voices. To bridge this gap, we suggest a framework for training singer identity encoders to extract representations suitable for various singing-related tasks, such as singing voice similarity and synthesis. We explore different self-supervised learning techniques on a large collection of isolated vocal tracks and apply data augmentations during training to ensure that the representations are invariant to pitch and content variations. We evaluate the quality of the resulting representations on singer similarity and identification tasks across multiple datasets, with a particular emphasis on out-of-domain generalization. Our proposed framework produces high-quality embeddings that outperform both speaker verification and wav2vec 2.0 pre-trained baselines on singing voice while operating at 44.1 kHz. We release our code and trained models to facilitate further research on singing voice and related areas.

title: Elastic anisotropy of layered or cracked media: alternative parameterisation
Creators: name: Adamus, Filip Piotr
Publisher: name: Memorial University of Newfoundland
Year: 2021

description: This thesis consists of six research papers. Each of them attempts to contribute to the field of elastic anisotropy. We investigate layered or cracked materials in the context of micromechanics and seismology. In the document, we discuss three following topics. In the first part, we study the overall (effective) elastic properties of a medium that is longwave equivalent to thin and parallel layers. To obtain the effective elasticity, we use the Backus average. Initially, we consider a typical scenario of isotropic layers that result in a transversely isotropic medium. We propose an alternative parameter that describes the anisotropy of such an effective material. We use it to indicate the presence of fluid within thin layers. Further, we discuss a crucial mathematical approximation of the Backus average and examine a particular case in which the approximation is inaccurate. This time, we allow the layers to exhibit lower symmetry than the isotropic one. In the second part, we consider an orthotropic symmetry, which is a good analogy to a cracked material. Instead of discussing the medium’s microstructure, we focus on the effective properties only. Specifically, we investigate the relations among orthotropic stiffnesses in the context of primary-wave phase velocity. We introduce the so-called cumulative moduli to describe the dependence of quasi P-wave velocity on each elasticity parameter. Such a parameterisation is useful for the velocity approximation. In the last part, we analyse cracked media in the context of both micromechanics and seismology. We propose an alternative way of obtaining effective elastic properties of a material with many parallel cracks. We represent a set of cracks by a thin layer embedded in a background medium, using Backus average; hence, we generalise the linear-slip method. Finally, we study the influence of cracks on the azimuthal variations of amplitude. We present patterns consisting of a series of azimuthal shapes that change with increasing concentration of inhomogeneities.
Mirror energy differences in T=1/2 f7/2-shell nuclei within isospin-dependent DFT

subject: FOS: Physical sciences

description: Background: Small asymmetry between neutrons and protons, caused by the differences in masses and charges of the up and down constituent quarks leads to the isospin symmetry breaking. The isospin non-conservation affects broad range of observables from superallowed Fermi weak interaction to isospin-forbidden electromagnetic rates. Its most profound and cleanest manifestation are systematic shifts in masses and excitation energies of mirror atomic nuclei. Purpose: Recently, we constructed the charge-dependent DFT that includes class II and III local interactions and demonstrated that the model allows for very accurate reproduction of Mirror and Triplet Displacement energies in a very broad range of masses. The aim of this work is to further test the charge-dependent functional by studying Mirror Energy Differences (MEDs) in function of angular momentum $I$. Methods: To compute MEDs we use DFT-rooted no core configuration interaction model. This post mean-field method restores rotational symmetry and takes into account configuration mixing within a space that includes relevant (multi)particle-(multi)hole Slater determinants. Results: We applied the model to $f_{7/2}$-shell mirror pairs of $A=43$, $45$, $47$, and $49$ focusing on MEDs in low-spin part (below band crossing) what allowed us to limit the model space to seniority one and three (one broken pair) configurations. Conclusions: We demonstrate that, for spins $I\leq 15/2$ being subject of the present study, our model reproduces well experimental MEDs which vary strongly in function of $I$ and $A$. The quality of model's predictions is comparable to the nuclear shell-model results by Bentley et al. Phys. Rev. C 92, 024310 (2015).

description: Quantile regression is a statistical method for estimating conditional quantiles of a response variable. In addition, for mean estimation, it is well known that quantile regression is more robust to outliers than $l_2$-based methods. By using the fused lasso penalty over a $K$-nearest neighbors graph, we propose an adaptive quantile estimator in a non-parametric setup. We show that the estimator attains optimal rate of $n^{-1/d}$ up to a logarithmic factor, under mild assumptions on the data generation mechanism of the $d$-dimensional data. We develop algorithms to compute the estimator and discuss methodology for model selection. Numerical experiments on simulated and real data demonstrate clear advantages of the proposed estimator over state of the art methods.
Exact representation and efficient approximations of linear model predictive control laws via HardTanh type deep neural networks

description: Deep neural networks have revolutionized many fields, including image processing, inverse problems, text mining and more recently, give very promising results in systems and control. Neural networks with hidden layers have a strong potential as an approximation framework of predictive control laws as they usually yield better approximation quality and smaller memory requirements than existing explicit (multi-parametric) approaches. In this paper, we first show that neural networks with HardTanh activation functions can exactly represent predictive control laws of linear time-invariant systems. We derive theoretical bounds on the minimum number of hidden layers and neurons that a HardTanh neural network should have to exactly represent a given predictive control law. The choice of HardTanh deep neural networks is particularly suited for linear predictive control laws as they usually require less hidden layers and neurons than deep neural networks with ReLU units for representing exactly continuous piecewise affine (or equivalently min-max) maps. In the second part of the paper we bring the physics of the model and standard optimization techniques into the architecture design, in order to eliminate the disadvantages of the black-box HardTanh learning. More specifically, we design trainable unfolded HardTanh deep architectures for learning linear predictive control laws based on two standard iterative optimization algorithms, i.e., projected gradient descent and accelerated projected gradient descent. We also study the performance of the proposed HardTanh type deep neural networks on a linear model predictive control application.

description: We propose three effective Hamiltonians which approximate atoms in very strong homogeneous magnetic fields $B$ modelled by the Pauli Hamiltonian, with fixed total angular momentum with respect to magnetic field axis. All three Hamiltonians describe $N$ electrons and a fixed nucleus where the Coulomb interaction has been replaced by $B$-dependent one-dimensional effective (vector valued) potentials but without magnetic field. Two of them are solvable in at least the one electron case. We briefly sketch how these Hamiltonians can be used to analyse the bottom of the spectrum of such atoms.

description: We calculate production rates for several hard processes in ultraperipheral proton-nucleus and nucleus-nucleus collisions at the LHC. The resulting high rates demonstrate that some key directions in small $x$ research proposed for HERA will be accessible at the LHC through these ultraperipheral processes. Indeed, these measurements can extend the HERA $x$ range by roughly a factor of 10 for similar virtualities. Nonlinear effects on the parton densities will thus be significantly more important in these collisions than at HERA.

description: We present a microscopic theory for quantum thermoelectric and heat transport in the Schwarzian regime of the Sachdev-Ye-Kitaev (SYK) model. As a charged fermion realization of the SYK model in nanostructures we assume a setup based on a quantum dot connected to the charge reservoirs through weak tunnel barriers. We analyze particle-hole symmetry breaking effects crucial for both Seebeck and Peltier coefficients. We show that the quantum charge and heat transport at low temperatures are defined by the interplay between elastic and inelastic processes such that the inelastic processes provide a leading contribution to the transport coefficients at the temperatures that are smaller compared to the charging energy. We demonstrate that both electric and thermal conductance obey a power law in temperature behavior, while thermoelectric, Seebeck, and Peltier coefficients are exponentially suppressed. This represents selective suppression of only nondiagonal transport coefficients. We discuss the validity of the Kelvin formula in the presence of a strong Coulomb blockade.

description: We analyze the multifractal spectra of daily foreign exchange rates for Japan, Hong-Kong, Korea, and Thailand with respect to the United States Dollar from 1991 to 2005. We find that the return time series show multifractal spectrum features for all four cases. To observe the effect of the Asian currency crisis, we also estimate the multifractal spectra of limited series before and after the crisis. We find that the Korean and Thai foreign exchange markets experienced a significant increase in multifractality compared to Hong-Kong and Japan. We also show that the multifractality is stronge related to the presence of high values of returns in the series.

description: Theoretical and numerical works indicate that a strong magnetic field should suppress fragmentation in dense cores. However, this has never been tested observationally in a relatively large sample of fragmenting massive dense cores. Here we use the polarization data obtained in the Submillimeter Array Legacy Survey of Zhang et al. to build a sample of 18 massive dense cores where both fragmentation and magnetic field properties are studied in a uniform way. We measured the fragmentation level, Nmm, within the field of view common to all regions, of 0.15 pc, with a mass sensitivity of about 0.5 Msun, and a spatial resolution of about 1000 au. In order to obtain the magnetic field strength using the Davis-Chandrasekhar-Fermi method, we estimated the dispersion of the polarization position angles, the velocity dispersion of the H13CO+(4-3) gas, and the density of each core, all averaged within 0.15 pc. A strong correlation is found between Nmm and the average density of the parental core, although with significant scatter. When large-scale systematic motions are separated from the velocity dispersion and only the small-scale (turbulent) contribution is taken into account, a tentative correlation is found between Nmm and the mass-to-flux ratio, as suggested by numerical and theoretical works.

description: A method for the calculation of the electronic structure of pyramidal self-assembled InAs/GaAs quantum dots is presented. The method is based on exploiting the exact $\bar{C}_{4}$ symmetry of the 8-band $k\cdot p$ Hamiltonian with the strain taken into account via the continuum mechanical model. The operators representing symmetry group elements were represented in the plane wave basis and the group projectors were used to find the symmetry adapted basis in which the corresponding Hamiltonian matrix is block diagonal with four blocks of approximately equal size. The quantum number of total quasi-angular momentum is introduced and the states are classified according to its value. Selection rules for interaction with electromagnetic field in the dipole approximation are derived. The method was applied to calculate electron and hole quasibound states in a periodic array of vertically stacked pyramidal self-assembled InAs/GaAs quantum dots for different values of the distance between the dots and external axial magnetic field. As the distance between the dots in an array is varied, an interesting effect of simultaneous change of ground hole state symmetry, type and the sign of miniband effective mass is predicted. This effect is explained in terms of the change of biaxial strain. It is also found that the magnetic field splitting of Kramer's double degenerate states is most prominent for the first and second excited state in the conduction band and that the magnetic field can both separate otherwise overlapping minibands and concatenate otherwise nonoverlapping minibands.

description: Atomic nuclei can be spontaneously deformed into non-spherical shapes as many-nucleon systems. We discuss to what extent a similar deformation takes place in many-electron systems. To this end, we employ several many-body methods, such as the unrestricted Hartree-Fock method, post-Hartree-Fock methods, and the density functional theory, to compute the electron density distribution in atoms. We show that the electron density distribution of open-shell atoms is deformed due solely to the single-particle valence orbitals, while the core part remains spherical. This is in contrast to atomic nuclei, which can be deformed collectively. We qualitatively discuss the origin for this apparent difference between atoms and nuclei by estimating the energy change due to deformation. We find that nature of the interaction plays an essential role for the collective deformation.

description: In this work we investigate two distinct extensions of the deformation procedure introduced in former works on deformed defects. The first extension deals with the use of deformation functions which can assume complex values, and the second concerns the possibility of making the deformation dependent on the defect solution of the model used to implement the deformation. These two extensions bring the deformation procedure to a significantly higher standard and allow to build interesting results, as we explicitly illustrate with examples of current interest to high energy physics.

Phonological awareness in children with phonological impairment : an intervention study
Creators: name: Chamut, Stephanie L.
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to investigate the effects of training phonological awareness on six 4- to 6-year-old children with phonological impairments. Furthermore, this study sought to discover what individual difference factors play a role in the acquisition of phonological skills. Six phonological awareness skills were tested: rhyme and alliteration oddity, rhyme and alliteration production, and bisyllable and monosyllable division. The children's phonological skills were tested before, during, and after the phonological awareness intervention. Each of the children received training in analysis and synthesis skills, and one of either rhyming skills or alliteration skills. For most of the children, the training took place once a week over eight weeks. The results show that intensive training in phonological awareness for children with phonological impairments improves their scores on phonological awareness measures. Also, many factors play a role in phonological awareness outcome such as phonological impairment, memory, amount of school experience, and amount of home practice.

description: Measures of quantum properties are essential to understanding the fundamental differences between quantum and classical systems as well as quantifying resources for quantum technologies. Here two broad classes of bosonic phase-space functions, which are filtered versions of the Glauber-Sudarshan $P$ function, are compared with regard to their ability to uncover nonclassical effects of light through their negativities. Gaussian filtering of the $P$ function yields the family of $s$-parametrized quasiprobabilities, while more powerful regularized nonclassicality quasiprobabilities are obtained by non-Gaussian filtering. A method is proposed to directly sample such phase-space functions for the restricted case of phase-independent quantum states from balanced homodyne measurements. This overcomes difficulties of previous approaches that manually append uniformly distributed optical phases to the measured quadrature data. We experimentally demonstrate this technique for heralded single- and two-photon states using balanced homodyne detection with varying efficiency. The $s$-parametrized quasiprobabilities, which can be directly sampled, are non-negative for detection efficiencies below 0.5. By contrast, we show that significant negativities of non-Gaussian filtered quasiprobabilities uncover nonclassical effects even for low efficiencies.

description: The free energy of a quantum oscillator in an arbitrary heat bath at a temperature T is given by a "remarkable formula" which involves only a single integral. This leads to a corresponding simple result for the entropy. The low temperature limit is examined in detail and we obtain explicit results both for the case of an Ohmic heat bath and a radiation heat bath. More general heat bath models are also examined. This enables us to determine the entropy at zero temperature in order to check the third law of thermodynamics in the quantum regime

description: Дальний Восток располагает агроклиматическими ресурсами для успешного выращивания мяты перечной с целью получения и переработки собственного сырья. Своеобразие почв и климата региона требуют уточнения традиционной технологии возделывания. Целью работы было испытание сортов и интродукция мяты перечной, совершенствование традиционной технологии ее выращивания в условиях Дальнего Востока. Результаты многолетних полевых исследований, проведенных в 1992-2018 гг. Приморским НИИСХ и Дальневосточным федеральным университетом, доказывают не только возможность, но и перспективность выращивания мяты. Длительная практическая работа показала, что главной особенностью возделывания мяты на Дальнем Востоке признается ее однолетняя культура. Оставлять сырьевую плантацию мяты для использования на второй и последующие годы нецелесообразно по следующим причинам. Во-первых, из-за слабой перезимовки (до полной гибели) растений, уходящих в зиму в удовлетворительном и хорошем состоянии. Во-вторых, из-за быстрого уплотнения почвы, которое угнетает развитие растений. Рыхление почвы в междурядьях затруднено поверхностным расположением корневищ. Растения второго года жизни начинают отрастать весной раньше, но развиваются медленнее вновь высаженных. В итоге выход сырья с единицы площади получается ниже на 15-25%. В-третьих, в посадках мяты быстро развиваются многолетние сорняки, с которыми при уплотненной почве трудно бороться. С каждым годом засоренность прогрессирует, чему способствуют замедленный рост и изреживаемость посадок после перезимовок. В-четвертых, зимостойкость сортов перестает быть сдерживающим фактором. Это дает возможность выбора сортов разных сроков сырьевой спелости и лучших по качественным показателям. Предлагаемая технология позволяет получать урожайность зеленой массы мяты 14-18 т/га в первом укосе и 8-11 т/га во втором с высоким качеством.

description: Представлены результаты конкурсного испытания перспективных сортов мягкой яровой пшеницы по технологическим и хлебопекарным качествам в условиях Приморского края. Исследования проводились в лаборатории селекции зерновых и крупяных культур ФГБНУ «ФНЦ агробиотехнологий Дальнего Востока им. А.К. Чайки « в 2017-2019 гг. В качестве стандарта был взят районированный сорт Приморская 39. При создании сортов яровой пшеницы в качестве родительских пар были использованы озимые формы, выделившие из экологического испытания по хлебопекарным и урожайным качествам зерна Кума, Спартанка, Зимница, Олимпия (ФГБНУ «Национальный центр зерна имени П.П. Лукъяненко« Краснодарский край), Дон 95, Спартак (ФГБНУ «АНЦ «Донской «, Ростовская область). Проведена оценка сортов конкурсного испытания по урожайности и качеству зерна. По урожайности (3,8 т/га) и элементам продуктивности (длина колоса, число зерен в колосе, продуктивная кустистость) выделились сорта: Приморская 222 (Приморская 39 х Спартанка) и Приморская 235 (Приморская 50 х Кума). Высокие технологические качества зерна (стекловидность, выход муки 1-го сорта, количество клейковины) отмечены у сортов Приморская 219 (07-0012 х Спартак) и Приморская 239 (Олимпия x Ken Hong14). Сорта характеризовались средним выходом муки от 57,8 до 66,5% и показателем седиментации 30-46 мл. Выделившиеся сорта яровой мягкой пшеницы Приморская 239 и Приморская 235 с высокой урожайностью (3,6-3,8 т/га) и хорошими хлебопекарными качествами (4,3 балла), рекомендуются для дальнейших исследований в селекционных программах.

description: We report first-principles calculations of the effects of quasiparticle self-energy and electron-hole interaction on the optical properties of single-walled BN nanotubes. Excitonic effects are shown to be even more important in BN nanotubes than in carbon nanotubes. Electron-hole interactions give rise to complexes of bright (and dark) excitons, which qualitatively alter the optical response. Excitons with binding energy larger than 2 eV are found in the (8,0) BN nanotubes. Moreover, unlike the carbon nanotubes, theory predicts that these exciton states are comprised of coherent supposition of transitions from several different subband pairs, giving rise to novel behaviors.

description: High-performance computing continues to increase its computing power and energy efficiency. However, energy consumption continues to rise and finding ways to limit and/or decrease it is a crucial point in current research. For high-performance MPI applications, there are rollback recovery based fault tolerance methods, such as uncoordinated checkpoints. These methods allow only some processes to go back in the face of failure, while the rest of the processes continue to run. In this article, we focus on the processes that continue execution, and propose a series of strategies to manage energy consumption when a failure occurs and uncoordinated checkpoints are used. We present an energy model to evaluate strategies and through simulation we analyze the behavior of an application under different configurations and failure time. As a result, we show the feasibility of improving energy efficiency in HPC systems in the presence of a failure.

description: Рассмотрены этапы развития и особенности современного состояния землепользования в Крыму. Отмечено, что в конце XX в. начале XXI в. экономическая нестабильность, общее снижение интенсивности хозяйственной деятельности оказали негативное влияние на сельхозпроизводство. Посевная площадь сельскохозяйственных культур на полуострове сокращалась до середины последнего десятилетия. В последние годы наблюдается некоторый рост данного показателя. В настоящее время режим увлажненности на территории региона, особенно в весенне-летние месяцы, является наиболее важным фактором, оказывающим влияние на урожайность и объемы производства продукции растениеводства. В этой ситуации особую актуальность приобретает формирование методологических основ совершенствования системы агротехнологий в решении задач поддержания почвенного плодородия. Одним из перспективных направлений повышения эффективности сельскохозяйственного производства в Крыму является расширение использования методов, обеспечивающих минимизацию обработки почвы, активное внедрение в практическую деятельность результатов научных исследований в области оценки биоэкологического соответствия.

description: Having in mind applications to gravitational wave theory (in connection with the radiation reaction problem), stochastic semiclassical gravity (in connection with the regularization of the noise kernel) and quantum field theory in higher-dimensional curved spacetime (in connection with the Hadamard regularization of the stress-energy tensor), we improve the DeWitt-Schwinger and Hadamard representations of the Feynman propagator of a massive scalar field theory defined on an arbitrary gravitational background by deriving higher-order terms for the covariant Taylor series expansions of the geometrical coefficients -- i.e., the DeWitt and Hadamard coefficients -- that define them.
