description: A general optimization framework is proposed for simultaneously transmitting and reflecting reconfigurable surfaces (STAR-RISs) with coupled phase shifts, which converges to the Karush-Kuhn-Tucker (KKT) optimal solution under some mild conditions. More particularly, the amplitude and phase-shift coefficients of STAR-RISs are optimized alternatively in closed form. To demonstrate the effectiveness of the proposed optimization framework, the throughput maximization problem is considered in a case study. It is rigorously proved that the KKT optimal solution is obtained. Numerical results confirm the effectiveness of the proposed optimization framework compared to baseline schemes.

Sizing, Operation, and Evaluation of Battery Energy Storage with Dynamic Line Rating and Deep Learning
Creators: Avkhimenia, Vadim
Publisher: name: University of Alberta Library
Year: 2023

Integration of renewables has the potential to reduce society’s reliance on carbon-based fuels. Sizing renewable-energy installations is key to making a successful business case for the construction of new assets. Dynamic thermal line rating is the amount of current in real-time that a transmission line can safely carry, and, if utilized together with utility-scale battery installations, has the potential to reduce the capacity and power rating of batteries.

Today, battery energy storage systems are operated generally with rule-based approaches where utility-scale batteries charge when they can, and discharge then they have to, or change their energy amount with the time of the day. This works aims to improve on that by introducing smart control of batteries using deep learning and deep reinforcement learning-based methods. Transmission operators today generally assume the line ampacity of the transmission lines to be stable, referred to as static line rating. Dynamic line rating, however, can be multiple times higher than static line rating, enabling the ability to sent more power across the transmission lines.

The aim of this work is to size battery energy storage systems taking into account dynamic thermal line rating, transmission line outages, and battery degradation, and explore decentralized control of batteries. A combination of non-linear programming for battery action prediction is used together with deep learning-based forecasting of ampacity and load. The approach is tested on IEEE 24-bus test grid. A deep reinforcement learning-based approach is utilized to predict battery actions, and test it on IEEE 6-bus test grid. A method for evaluating battery capacity and power rating sizes based on comparing the selection criteria with the allowed tolerance in unserved energy, unserved energy duration, and the number of unserved energy events is presented. A method to generate synthetic 100-step time series of Alberta electricity pool prices and dynamic thermal line rating is demonstrated, that can be used to supplement existing data sets, and be applied in reinforcement-learning simulations.

description: In this paper we investigate multivariate integration in weighted unanchored Sobolev spaces of smoothness of arbitrarily high order. As quadrature points we employ higher order polynomial lattice point sets over $\mathbb{F}_{2}$ which are randomly digitally shifted and then folded using the tent transformation. We first prove the existence of good higher order polynomial lattice rules which achieve the optimal rate of the mean square worst-case error, while reducing the required degree of modulus by half as compared to higher order polynomial lattice rules whose quadrature points are randomly digitally shifted but not folded using the tent transformation. Thus we are able to restrict the search space of generating vectors significantly. We then study the component-by-component construction as an explicit means of obtaining good higher order polynomial lattice rules. In a way analogous to [J. Baldeaux, J. Dick, G. Leobacher, D. Nuyens, F. Pillichshammer, Numer. Algorithms, 59 (2012) 403--431], we show how to calculate the quality criterion efficiently and how to obtain the fast component-by-component construction using the fast Fourier transform. Our result generalizes the previous result shown by [L.L. Cristea, J. Dick, G. Leobacher, F. Pillichshammer, Numer. Math., 105 (2007) 413--455], in which the degree of smoothness is fixed at 2 and classical polynomial lattice rules are considered.
K$^0_{\rm S}$ and $\rm Λ$ production in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV

description: The ALICE measurement of K$^0_{\rm S}$ and $\rmΛ$ production at mid-rapidity in Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 2.76$ TeV is presented. The transverse momentum ($p_{\rm T}$) spectra are shown for several collision centrality intervals and in the $p_{\rm T}$ range from 0.4 GeV/$c$ (0.6 GeV/$c$ for $\rmΛ$) to 12 GeV/$c$. The $p_{\rm T}$ dependence of the $\rm Λ$/K$^0_{\rm S}$ ratios exhibits maxima in the vicinity of 3 GeV/$c$, and the positions of the maxima shift towards higher $p_{\rm T}$ with increasing collision centrality. The magnitude of these maxima increases by almost a factor of three between most peripheral and most central Pb-Pb collisions. This baryon excess at intermediate $p_{\rm T}$ is not observed in pp interactions at sqrt(s) = 0.9 TeV and at sqrt(s) = 7 TeV. Qualitatively, the baryon enhancement in heavy-ion collisions is expected from radial flow. However, the measured $p_{\rm T}$ spectra above 2 GeV/$c$ progressively decouple from hydrodynamical-model calculations. For higher values of $p_{\rm T}$, models that incorporate the influence of the medium on the fragmentation and hadronization processes describe qualitatively the $p_{\rm T}$ dependence of the $\rmΛ$/K$^0_{\rm S}$ ratio.

description: Let $P$ be a classical pseudodifferential operator of complex order $m$ on an $n$-dimensional smooth manifold $Ω_1$. For the truncation $P_Ω$ to a smooth subset $Ω$ there is a well-known theory of boundary value problems when $P_Ω$ has the transmission property (preserves $C^\infty (\barΩ)$) and is of integer order; the calculus of Boutet de Monvel. Many interesting operators, such as for example complex powers of the Laplacian $(-Δ)^μ$ with noninteger mu, are not covered. They have instead the mu-transmission property defined in Hörmander's books, mapping $x_n^μC^\infty (\barΩ)$ into $C^\infty (\barΩ)$. In an unpublished lecture note from 1965, Hörmander described an $L_2$-solvability theory for mu-transmission operators, departing from Vishik and Eskin's results. We here develop the theory in $L_p$ Sobolev spaces ($1

description: We continue the investigation of Bernstein-von Mises theorems for nonparametric Bayes procedures from [Ann. Statist. 41 (2013) 1999-2028]. We introduce multiscale spaces on which nonparametric priors and posteriors are naturally defined, and prove Bernstein-von Mises theorems for a variety of priors in the setting of Gaussian nonparametric regression and in the i.i.d. sampling model. From these results we deduce several applications where posterior-based inference coincides with efficient frequentist procedures, including Donsker- and Kolmogorov-Smirnov theorems for the random posterior cumulative distribution functions. We also show that multiscale posterior credible bands for the regression or density function are optimal frequentist confidence bands.

A sweet regulatory landscape of the glycome
Creators: Chu, Thu
Publisher: name: University of Alberta Library
Year: 2023

Glycosylation is one of the most abundant and diverse post-translational modifications. Glycans participate in various key biological functions and processes including immunity, cell adhesion, endocytosis, exocytosis, molecular trafficking, and signal transduction. Previous work from our lab identified microRNAs (miRNAs, miRs) as key regulators of glycosylation genes (glycogenes). miRs are small non-coding RNAs that fine-tune protein expression through binding to messenger RNA (mRNA). miRs regulate networks of genes that work to control a specific biological process, tightening the expression range for critical genes. By mapping the targets of miRNA involved in specific biological processes or disease states, we can determine genes that are important drivers in that process or disease, defined as the miRNA Proxy Approach 1, 2. However, this approach is dependent on an accurate understanding of miRNA:mRNA interactions.

Current identification of miR:glycogene interactomes is hindered by the low accuracy of prediction (17-66%), the low expression of glycogenes (complicating transcriptomic analysis  and RISC complex pulldowns), and suboptimal throughput ((only around 0.01% of all predicted human miR:target interactions have been validated experimentally) of more direct miR:mRNA validations (mostly luciferase assay). To overcome these obstacles, our laboratory has developed miRFluR high-throughput experimental mapping of miR:glycogene interactions. Thus, we were able to obtain a comprehensive dataset of miRNA regulatory networks for glycosylation enzymes including B3GLCT, OGT and OGA. In the work of miR-B3GLCT interaction network, we successfully utilized downregulatory miR network to predict B3GLCT biological functions as supporting evidence for our miRNA proxy hypothesis 3. In addition, we not only identified miR impacting in the 3’ untranslated region (3’UTR) but also expanding our platform to the 5’UTR. In summary, this work contributed to decipher the glycosylation code and understanding biological functions of certain regulatory networks.

description: Breast cancer is the second major cause of death worldwide among women. Co-delivery of anticancer drugs and nucleic acids targeting the apoptosis pathway could be a promising new approach. In the present study, we synthesized a novel nanostructure for the co-delivery of curcumin and siRNA to breast cancer cells. Curcumin-loaded polylactic-co-glycolic acid (PLGA) was synthesized using an O/W emulsion-solvent diffusion method. It was coated with polyethylenimine (PEI) and subsequently complexed with Bcl-2 siRNA. Also, nanoparticles were characterized such as zeta potential, size distribution and drug encapsulation. Finally, the cytotoxicity of NP and Bcl-2 expression was evaluated. The curcumin-loaded PLGA nanoparticles were 70 nm in size, and increased to 84 nm after incorporation of PEI plus Bcl-2 siRNA. The encapsulation ratio of the drug in our nanoparticle was 78%. Cellular internalization of PLGA-CUR-PEI/Bcl-2 siRNA NPs was confirmed by fluorescence microscopy with the broadcasting of the fluorescence in the cytoplasm and into the nucleus. The results of the cell viability assay revealed that curcumin-loaded PLGA coated with PEI and Bcl-2 siRNA exhibited the highest cytotoxicity against the T47D cell line, while the siRNA decreased the Bcl-2 expression by 90.7%. The co-delivery of curcumin plus Bcl-2 siRNA with the PLGA-PEI nanosystem could be a synergistic drug carrier against breast cancer cells.

description: We study one-dimensional QCD at finite quark density by using the sign optimization framework. The fermion sign problem is mitigated by deforming the path integral domain, $SU(3)$ to a complexified one ${\cal M} \subset SL(3)$, explicitly constructed to reduce the phase fluctuations. The complexification is constructed using the angular representation of $SU(3)$. We provide a physical explanation of the optimization procedure in terms of complex saddle points. This picture connects the sign optimization framework to the generalized Lefschetz thimbles.

description: Recent theoretical works have proposed atomic clocks based on narrow optical transitions in highly charged ions. The most interesting candidates for searches of physics beyond the Standard Model are those which occur at rare orbital crossings where the shell structure of the periodic table is reordered. There are only three such crossings expected to be accessible in highly charged ions, and hitherto none have been observed as both experiment and theory have proven difficult. In this work we observe an orbital crossing in a system chosen to be tractable from both sides: Pr9+. We present electron beam ion trap measurements of its spectra, including the inter-configuration lines that reveal the sought-after crossing. With state-of-the-art calculations we show that the proposed nHz-wide clock line has a very high sensitivity to variation of the fine-structure constant, α, and violation of local Lorentz invariance; and has extremely low sensitivity to external perturbations.

description: The novel modulus-based approach was developed to characterize the compression behavior of the materials and how it results into tablet mechanical strength (TMS) of the final tablet. The force–displacement profile for the model materials (Vivapur® 101, Starch 1500®, Emcompress®, and Tablettose® 100) was generated at different compression pressures (100, 150, and 200 MPa) and speeds (0.35, 0.55, and 0.75 m/s) using compaction emulator (Presster™). A generated continuous compression profile was evaluated with Heckel plot and the proposed material modulus method. The computed compression parameters were qualitatively and quantitatively correlated with TMS by principal component analysis and principal component regression, respectively. Compression modulus has negatively correlated, while decompression modulus is positively correlated to TMS. Proposed modulus descriptors are independent of particle density measurements required for the Heckel method and could overcome the limitations of the Heckel method to evaluate the decompression phase. Based on the outcome of the study, a two-dimensional compression and decompression modulus classification system (CDMCS) was proposed. The proposed CDMCS could be used to define critical material attributes in the early development stage or to understand reasons for tablet failure in the late development stage.
Discourse Analysis of Indigenous Women's Sexuality in News Media
Creators: Laboucan, Amei-lee
Publisher: name: University of Alberta Library
Year: 2023

Indigenous women’s deaths are routinely underreported by mainstream media. “Discourse Analysis of Indigenous Women’s Sexuality in News Media” finds that The Globe and Mail, Edmonton Journal, Vancouver Sun, Winnipeg Free Press, and Toronto Star rely on stereotypes steeped in settler colonialism to report on the deaths of Helen Betty Osborne, Pamela George, Cindy Gladue, and Tina Fontaine. “Discourse Analysis of Indigenous Women’s Sexuality in News Media” also finds that mainstream media does not contextualise violence against Indigenous women within colonialism in Canada, ignores the voices of the victims’ families, and engages settler moves to innocence when reporting on the perpetrators who have been accused or convicted of murdering Helen Betty Osborne, Pamela George, Cindy Gladue, and Tina Fontaine. Finally, “Discourse Analysis of Indigenous Women’s Sexuality in News Media” proposes that Indigenous journalists are best equipped to report on Indigenous sexuality because of their more nuanced understanding of Indigenous women and sexuality. Furthermore, Indigenous people authoring stories about Indigenous sexuality is to reclaim a suppressed way of being. It also counters the singular narrative of Indigenous women as hypersexual people who are victims of sex-murder and redefines Indigenous women as fulsome people who experience the world’s pleasures including gender expression, the pleasures of sex, and sexual expression. This thesis uses Indigenous feminism and intersectionality as theoretical concepts and critical discourse analysis as a methodology, following the ethic of suspending damage.

description: Ultrastable high-power laser systems are essential components of the long baseline interferometers that detected the first gravitational waves from merging black holes and neutron stars. One way to further increase the sensitivity of current generation gravitational wave detectors (GWDs) is to increase the laser power injected into the interferometers. In this Letter, we describe and characterize a 72 W and a 114 W linearly polarized, single-frequency laser system at a wavelength of 1064 nm, each based on single-pass Nd:YVO4 power amplifiers. Both systems have low power and frequency noise and very high spatial purity with less than 10.7% and 2.9% higher order mode content, respectively. We demonstrate the simple integration of these amplifiers into the laser stabilization environment of operating GWDs and show stable low-noise operation of one of the amplifier systems in such an environment for more than 45 days.

description: Identifying intersections among a set of d-dimensional rectangular regions (d-rectangles) is a common problem in many simulation and modeling applications. Since algorithms for computing intersections over a large number of regions can be computationally demanding, an obvious solution is to take advantage of the multiprocessing capabilities of modern multicore processors. Unfortunately, many solutions employed for the Data Distribution Management service of the High Level Architecture are either inefficient, or can only partially be parallelized. In this paper we propose the Interval Tree Matching (ITM) algorithm for computing intersections among d-rectangles. ITM is based on a simple Interval Tree data structure, and exhibits an embarrassingly parallel structure. We implement the ITM algorithm, and compare its sequential performance with two widely used solutions (brute force and sort-based matching). We also analyze the scalability of ITM on shared-memory multicore processors. The results show that the sequential implementation of ITM is competitive with sort-based matching; moreover, the parallel implementation provides good speedup on multicore processors.

The Role of the Core Energy in the Vortex Nernst Effect
Creators: name: Wachtel, Gideon

Year: 2013
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: We present an analytical study of diamagnetism and transport in a film with superconducting phase fluctuations, formulated in terms of vortex dynamics within the Debye-Hückle approximation. We find that the diamagnetic and Nernst signals decay strongly with temperature in a manner which is dictated by the vortex core energy. Using the theory to interpret Nernst measurements of underdoped La$_{2-x}$Sr$_x$CuO$_4$ above the critical temperature regime we obtain a considerably better fit to the data than a fit based on Gaussian order-parameter fluctuations. Our results indicate that the core energy in this system scales roughly with the critical temperature and is significantly smaller than expected from BCS theory. Furthermore, it is necessary to assume that the vortex mobility is much larger than the Bardeen-Stephen value in order to reconcile conductivity measurements with the same vortex picture. Therefore, either the Nernst signal is not due to superconducting phase fluctuations, or that vortices in underdoped La$_{2-x}$Sr$_x$CuO$_4$ have highly unconventional properties.

A phase-shift-periodic parallel boundary condition for low-magnetic-shear scenarios

description: We formulate a generalized periodic boundary condition as a limit of the standard twist-and-shift parallel boundary condition that is suitable for simulations of plasmas with low magnetic shear. This is done by applying a phase shift in the binormal direction when crossing the parallel boundary. While this phase shift can be set to zero without loss of generality in the local flux-tube limit when employing the twist-and-shift boundary condition, we show that this is not the most general case when employing periodic parallel boundaries, and may not even be the most desirable. A non-zero phase shift can be used to avoid the convective cells that plague simulations of the three-dimensional Hasegawa-Wakatani system, and is shown to have measurable effects in periodic low-magnetic-shear gyrokinetic simulations. We propose a numerical program where a sampling of periodic simulations at random pseudo-irrational flux surfaces are used to determine physical observables in a statistical sense. This approach can serve as an alternative to applying the twist-and-shift boundary condition to low-magnetic-shear scenarios which, while more straightforward, can be computationally demanding.

description: The ability of laser systems to emit different adjustable temporal pulse profiles and patterns is desirable for a broad range of applications. While passive mode-locking techniques have been widely employed for the realization of ultrafast laser pulses with mainly Gaussian or hyperbolic secant temporal profiles, the generation of versatile pulse shapes in a controllable way and from a single laser system remains a challenge. Here we show that a nonlinear amplifying loop mirror (NALM) laser with a bandwidth-limiting filter (in a nearly dispersion-free arrangement) and a short integrated nonlinear waveguide enables the realization and distinct control of multiple mode-locked pulsing regimes (e.g., Gaussian pulses, square waves, fast sinusoidal-like oscillations) with repetition rates that are variable from the fundamental (7.63 MHz) through its 205th harmonic (1.56 GHz). These dynamics are described by a newly developed and compact theoretical model, which well agrees with our experimental results. It attributes the control of emission regimes to the change of the NALM response function that is achieved by the adjustable interplay between the NALM amplification and the nonlinearity. In contrast to previous square wave emissions, we experimentally observed that an Ikeda instability was responsible for square wave generation. The presented approach enables laser systems that can be universally applied to various applications, e.g., spectroscopy, ultrafast signal processing and generation of non-classical light states.
Numerical solution of gravitational dynamics in asymptotically anti-de Sitter spacetimes

description: A variety of gravitational dynamics problems in asymptotically anti-de Sitter (AdS) spacetime are amenable to efficient numerical solution using a common approach involving a null slicing of spacetime based on infalling geodesics, convenient exploitation of the residual diffeomorphism freedom, and use of spectral methods for discretizing and solving the resulting differential equations. Relevant issues and choices leading to this approach are discussed in detail. Three examples, motivated by applications to non-equilibrium dynamics in strongly coupled gauge theories, are discussed as instructive test cases. These are gravitational descriptions of homogeneous isotropization, collisions of planar shocks, and turbulent fluid flows in two spatial dimensions.

Publisher: name: University Library Heidelberg
Year: 2014

description: Digitalisierung von Kulturgut steht bei Bibliotheken hoch im Kurs. Doch da die entstehenden digitalen Sammlungen meist nicht im Volltext durchsuchbar sind, bleiben sie in ihrer Nutzbarkeit beschränkt. Druckwerke können durch OCR erschlossen werden, doch die elektronisch erzeugten Texte sind trotz allem technischen Fortschritt nach wie vor nicht fehlerfrei. Für Handschriften kommt weiterhin meist nur die Transkription durch menschliche Bearbeiter in Frage. Durch Crowdsourcing werden die Nutzer an der Erstellung und Korrektur von Volltexten beteiligt. Dieser Artikel stellt drei Beispiel unterschiedlicher Größe und Zielsetzung zur Erschließung von Zeitungsbeständen und neuzeitlichen Autographen durch freiwillige Beiträger vor. Er argumentiert, dass Crowdsourcing für die Erschließung historischer Bibliotheksbestände geeignet ist und sich durch die aktive Beteiligung der Nutzer ein Mehrwert für beide Seiten ergibt.

Modeling Dust Production, Growth, and Destruction in Reionization-Era Galaxies with the CROC Simulations: Methods and Parameter Exploration

Publisher: name: arXiv
Year: 2022
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: We introduce a model for the explicit evolution of interstellar dust in a cosmological galaxy formation simulation. We post-process a simulation from the Cosmic Reionization on Computers project (CROC, Gnedin 2014), integrating an ordinary differential equation for the evolution of the dust-to-gas ratio along pathlines in the simulation sampled with a tracer particle technique. This model incorporates the effects of dust grain production in asymptotic giant branch (AGB) star winds and supernovae (SN), grain growth due to the accretion of heavy elements from the gas phase of the interstellar medium (ISM), and grain destruction due to thermal sputtering in the high temperature gas of supernova remnants (SNRs). A main conclusion of our analysis is the importance of a carefully chosen dust destruction model, for which different reasonable parameterizations can predict very different values at the $\sim 100$ pc resolution of the ISM in our simulations. We run this dust model on the single most massive galaxy in a 10$h^{-1}$ co-moving Mpc box, which attains a stellar mass of $\sim 2\times10^9 M_{\odot}$ by $z=5$. We find that the model is capable of reproducing dust masses and dust-sensitive observable quantities broadly consistent with existing data from high-redshift galaxies. The total dust mass in the simulated galaxy is somewhat sensitive to parameter choices for the dust model, especially the timescale for grain growth due to accretion in the ISM. Consequently, observable quantities that can constrain galaxy dust masses at these epochs are potentially useful for placing constraints on dust physics.

On Demazure and local Weyl modules for affine hyperalgebras

description: We establish the existence of Demazure flags for graded local Weyl modules for hyper current algebras in positive characteristic. If the underlying simple Lie algebra is simply laced, the flag has length one, i.e., the graded local Weyl modules are isomorphic to Demazure modules. This extends to the positive characteristic setting results of Fourier-Littelmann and Naoi for current algebras in characteristic zero. Using this result, we prove that the character of local Weyl modules for hyper loop algebras depend only on the highest weight, but not on the (algebraically closed) ground field, and deduce a tensor product factorization for them.

description: A cryogenic radio-frequency ion trap system designed for quantum logic spectroscopy of highly charged ions (HCI) is presented. It includes a segmented linear Paul trap, an in-vacuum imaging lens, and a helical resonator. We demonstrate ground state cooling of all three modes of motion of a single 9Be+ ion and determine their heating rates as well as excess axial micromotion. The trap shows one of the lowest levels of electric field noise published to date. We investigate the magnetic-field noise suppression in cryogenic shields made from segmented copper, the resulting magnetic field stability at the ion position and the resulting coherence time. Using this trap in conjunction with an electron beam ion trap and a deceleration beamline, we have been able to trap single highly charged Ar13+ (Ar XIV) ions concurrently with single Be+ ions, a key prerequisite for the first quantum logic spectroscopy of a HCI. This major stepping stone allows us to push highly-charged-ion spectroscopic precision from the gigahertz to the hertz level and below.
