description: It is known that the model checking problem for the modal mu-calculus reduces to the problem of solving a parity game and vice-versa. The latter is realised by the Walukiewicz formulas which are satisfied by a node in a parity game iff player 0 wins the game from this node. Thus, they define her winning region, and any model checking algorithm for the modal mu-calculus, suitably specialised to the Walukiewicz formulas, yields an algorithm for solving parity games. In this paper we study the effect of employing the most straight-forward mu-calculus model checking algorithm: fixpoint iteration. This is also one of the few algorithms, if not the only one, that were not originally devised for parity game solving already. While an empirical study quickly shows that this does not yield an algorithm that works well in practice, it is interesting from a theoretical point for two reasons: first, it is exponential on virtually all families of games that were designed as lower bounds for very particular algorithms suggesting that fixpoint iteration is connected to all those. Second, fixpoint iteration does not compute positional winning strategies. Note that the Walukiewicz formulas only define winning regions; some additional work is needed in order to make this algorithm compute winning strategies. We show that these are particular exponential-space strategies which we call eventually-positional, and we show how positional ones can be extracted from them.

description: Twenty miles northeast of San Antonio, between the small cities of Live Oak, Shertz, Selma, and Universal City a true architectural and city planning masterpiece sits, protected from outsiders, and at first glance it seems, from time. Randolph Air Force Base, built in 1931, has endured the decades, providing a beautiful, yet functional setting for the training of a many of the Air Force pilots of the twentieth century. Randolph enjoys a prominent history, rich with accomplished architects, powerful Generals, and an incredibly talented Lieutenant. As a Historic Preservation case study, Randolph provides a unique example of continual and loving preservation, as well as innovative and effective adaptive reuse. A National Historic Landmark, as well as National Register listed Historic District, Randolph has successfully ridden the waves of change, gracefully adapting, yet keeping a traditional and elegant air. Today, it faces budgetary constraints that could impact its preservation in the future. Privatization of its large historic housing inventory, the pressures of an active Air Force Base, as well as a staff of one preservation officer combine to create a complicated situation for this “Showplace of the Air Force.”
Incompressible limit of mechanical model of tumor growth with viscosity

description: Various models of tumor growth are available in the litterature. A first class describes the evolution of the cell number density when considered as a continuous visco-elastic material with growth. A second class, describes the tumor as a set and rules for the free boundary are given related to the classical Hele-Shaw model of fluid dynamics. Following the lines of previous papers where the material is described by a purely elastic material, or when active cell motion is included, we make the link between the two levels of description considering the 'stiff pressure law' limit. Even though viscosity is a regularizing effect, new mathematical difficulties arise in the visco-elastic case because estimates on the pressure field are weaker and do not imply immediately compactness. For instance, traveling wave solutions and numerical simulations show that the pressure may be discontinous in space which is not the case for the elastic case.

Publisher: name: Zenodo
Year: 2024

description: Fine-structure constant, also known as Sommerfeld's constant, commonly denoted by α (the Greek letter alpha), is a fundamental physical constant characterizing the strength of the electromagnetic interaction between elementary charged particles. It has couple of equivalent definitions. In current paper we try to approximate fine-structure constant with fractional elementary charge expressions, ignoring charge measurement units, using only elementary charge absolute value.

description: We have found an infinite dimensional manifold of exact solutions of the Navier-Stokes loop equation for the Wilson loop in decaying Turbulence in arbitrary dimension $d >2$. This solution family is equivalent to a fractal curve in complex space $\mathbb C^d$ with random steps parametrized by $N$ Ising variables $σ_i=\pm 1$, in addition to a rational number $\frac{p}{q}$ and an integer winding number $r$, related by $\sum σ_i = q r$. This equivalence provides a dual theory describing a strong turbulent phase of the Navier-Stokes flow in $\mathbb R_d$ space as a random geometry in a different space, like ADS/CFT correspondence in gauge theory. From a mathematical point of view, this theory implements a stochastic solution of the unforced Navier-Stokes equations. For a theoretical physicist, this is a quantum statistical system with integer-valued parameters, satisfying some number theory constraints. Its long-range interaction leads to critical phenomena when its size $N \rightarrow \infty$ or its chemical potential $μ\rightarrow 0$. The system with fixed $N$ has different asymptotics at odd and even $N\rightarrow \infty$, but the limit $μ\rightarrow 0$ is well defined. The energy dissipation rate is analytically calculated as a function of $μ$ using methods of number theory. It grows as $ν/μ^2$ in the continuum limit $μ\rightarrow 0$, leading to anomalous dissipation at $μ\propto \sqrtν \to 0$. The same method is used to compute all the local vorticity distribution, which has no continuum limit but is renormalizable in the sense that infinities can be absorbed into the redefinition of the parameters. The small perturbation of the fixed manifold satisfies the linear equation we solved in a general form. This perturbation decays as $t^{-λ}$, with a continuous spectrum of indexes $λ$ in the local limit $μ\to 0$.

Topological Recursion for Transalgebraic Spectral Curves and the TR/QC Connection
Creators: Weller, Quinten
Publisher: name: University of Alberta Library
Year: 2022

The topological recursion is a construction in algebraic geometry that takes in the data of a so-called spectral curve, $\mathcal{S}=\left(\Sigma,x,y\right)$ where $\Sigma$ is a Riemann surface and $x,y:\Sigma\to\mathbb{C}_\infty$ are meromorphic, and recursively constructs correlators which, in applications, are then interpreted as generating functions. In many of these applications, for example the $r$-spin Hurwitz case $\mathcal{S}=\left(\mathbb{C},x(z)=z{\rm e}^{-z^r},y(z)={\rm e}^{z^r}\right)$, $x$ has essential singularities when the underlying Riemann surface is compactified. Previously, these essential singularities have been ignored and the topological recursion considered on the non-compact surface. Here we argue that it is more natural to include the essential singularities as ramification points and give the corresponding definition for topological recursion; that is, a topological recursion for \emph{transalgebraic} spectral curves rather than \emph{algebraic} spectral curves. We use this definition to shed light on the TR/QC connection, Hurwitz theory, the Gromov-Witten invariants of $\mathbb{CP}^1$, and mirror curves.

description: Cognitive function is driven by dynamic interactions between large-scale neural circuits or networks, enabling behavior. Fundamental principles constraining these dynamic network processes have remained elusive. Here we use network control theory to offer a mechanistic explanation for how the brain moves between cognitive states drawn from the network organization of white matter microstructure. Our results suggest that densely connected areas, particularly in the default mode system, facilitate the movement of the brain to many easily-reachable states. Weakly connected areas, particularly in cognitive control systems, facilitate the movement of the brain to difficult-to-reach states. Areas located on the boundary between network communities, particularly in attentional control systems, facilitate the integration or segregation of diverse cognitive systems. Our results suggest that structural network differences between the cognitive circuits dictate their distinct roles in controlling dynamic trajectories of brain network function.

description: We present the wavelength-resolved reverberation mapping (RM) of combined MgII and UV FeII broad-line emissions for two intermediate redshifts (z$\sim$1), luminous quasars - HE 0413-4031 and HE 0435-4312, monitored by the SALT and 1-m class telescopes between 2012-2022. Through this technique, we aim to disentangle the Mg II and FeII emission regions and to build a radius-luminosity relation for UV FeII emission, which has so far remained unconstrained. Several methodologies have been applied to constrain the time delays for total MgII and FeII emissions. In addition, this technique is performed to quantify the inflow or outflow of broad-line region gas around the supermassive black hole and to disentangle the emission/emitting regions from lines produced in proximity to each other. The mean total FeII time delay is nearly equal to the mean total Mg II time delay for HE 0435-4312 suggesting a co-spatiality of their emissions. However, in HE 0413-4031, the mean FeII time delay is found to be longer than the mean MgII time delay, suggesting that FeII is produced at longer distances from the black hole. The UV Fe II R-L relation is updated with these two quasars and compared with the optical FeII relation, which suggests that the optical FeII region is located further than the UV FeII by a factor of 1.7-1.9 i.e. $R_{\rm FeII-opt}\sim(1.7-1.9)R_{\rm FeII-UV}$. We detected a weak pattern in the time delay vs. wavelength relation, suggesting that the MgII broad-line originates a bit closer to the SMBH than the UV FeII, however, the difference is not very significant. Comparison of MgII, UV, and optical FeII R-L relations suggests that the difference may be larger for lower-luminosity sources, possibly with the MgII emission originating further from the SMBH. In the future, more RM data will be acquired to put better constraints on these trends, in particular the UV FeII R-L relation.

description: Ultralight bosons are predicted in many extensions to the Standard Model and are popular dark matter candidates. The black hole superradiance mechanism allows for these particles to be probed using only their gravitational interaction. In this scenario, an ultralight boson cloud may form spontaneously around a spinning black hole and extract a non-negligible fraction of the black hole's mass. These oscillating clouds produce quasi-monochromatic, long-duration gravitational waves that may be detectable by ground-based or space-based gravitational wave detectors. We discuss the capability of a new long-duration signal tracking method, based on a hidden Markov model, to detect gravitational wave signals generated by ultralight vector boson clouds, including cases where the signal frequency evolution timescale is much shorter than that of a typical continuous wave signal. We quantify the detection horizon distances for vector boson clouds with current- and next-generation ground-based detectors. We demonstrate that vector clouds hosted by black holes with mass $\gtrsim 60 M_{\odot}$ and spin $\gtrsim 0.6$ are within the reach of current-generation detectors up to a luminosity distance of $\sim 1$ Gpc. This search method enables one to target vector boson clouds around remnant black holes from compact binary mergers detected by gravitational-wave detectors. We discuss the impact of the sky localization of the merger events and demonstrate that a typical remnant black hole reasonably well-localized by the current generation detector network is accessible in a follow-up search.

Multiple Primary Tumors in Oral Cancer : Patient Characteristics and Survival Patterns
Creators: Sawani, Salima Asifali
Publisher: name: University of Alberta Library
Year: 2022

Objectives: To identify the risk factors of MPT development in oral cancer patients and to examine the survival rates of oral cancer patients with MPTs and its associated factors.

Materials and Methods: We retrospectively studied the data of 3,549 patients diagnosed with primary oral cancer using the Alberta Cancer Registry database between 2005 and 2020.

Results: A total of 513 patients developed MPTs with an overall incidence of 14.5%. Among them, 78% MPTs were metachronous tumors and the average time interval of development of 1st MPT was 4.04±3.67 years. The proportion of comorbid conditions was significantly higher in MPT patients as compared to non-MPT patients (52% vs. 40.02%, p < 0.001). The oral cavity cancer (OCC) as a primary tumor was found to be significantly greater in patients who developed MPTs (53.4%, p = 0.002). The most common MPT site was oral region (31.8%) followed by lungs (19.1%) and digestive system (12.3%). Advanced age, average income, co-morbidities including COPD, diabetes and cardiovascular disease, and increased duration from diagnosis to treatment were found to be potential risk factors for MPT development in POC patients. Survival analysis revealed a sharp decrease in survival rate of oral cancer survivors after developing MPTs (from 70% to 47%, p = 0.004). Multivariate regression analyses indicated that age > 45-year, BMI < 18.5, synchronous tumors, stage III and IV POC, > 2 comorbid conditions and MPT developing in digestive system had a poor disease specific survival.

Conclusions: Development of MPT is a significant risk in oral cancer patients leading to increase mortality rates. Long-term follow-up is necessary for oral cancer patients to diagnose the occurrence of MPTs to improve the prognosis of the disease.
Sample Efficient Model-free Reinforcement Learning from LTL Specifications with Optimality Guarantees

description: Linear Temporal Logic (LTL) is widely used to specify high-level objectives for system policies, and it is highly desirable for autonomous systems to learn the optimal policy with respect to such specifications. However, learning the optimal policy from LTL specifications is not trivial. We present a model-free Reinforcement Learning (RL) approach that efficiently learns an optimal policy for an unknown stochastic system, modelled using Markov Decision Processes (MDPs). We propose a novel and more general product MDP, reward structure and discounting mechanism that, when applied in conjunction with off-the-shelf model-free RL algorithms, efficiently learn the optimal policy that maximizes the probability of satisfying a given LTL specification with optimality guarantees. We also provide improved theoretical results on choosing the key parameters in RL to ensure optimality. To directly evaluate the learned policy, we adopt probabilistic model checker PRISM to compute the probability of the policy satisfying such specifications. Several experiments on various tabular MDP environments across different LTL tasks demonstrate the improved sample efficiency and optimal policy convergence.

description: The existence of luminous quasars (QSO) at the Epoch of Reionization (EoR; i.e. z>6) powered by supermassive black holes (SMBH) with masses $\gtrsim10^9~M_\odot$ challenges models of early SMBH formation. To shed light on the nature of these sources we started a multiwavelength programme based on a sample of 18 HYPerluminous quasars at the Epoch of ReionizatION (HYPERION). These are the luminous QSOs whose SMBH must have had the fastest mass growth during the Universe first Gyr. In this paper we present the HYPERION sample and report on the first of the 3 years planned observations of the 2.4 Ms XMM-Newton Multi-Year Heritage program on which HYPERION is based. The goal of this program is to accurately characterize the X-ray nuclear properties of QSOs at the EoR. Through a joint X-ray spectral analysis of 10 sources, in the rest-frame $\sim2-50$ keV range, we report a steep average photon index ($Γ\sim2.4\pm0.1$). Absorption is not required. The average $Γ$ is inconsistent at $\geq4σ$ level with the canonical 1.8-2 value measured in QSO at z<6. This spectral slope is also much steeper than that reported in lower-z QSOs with similar luminosity or accretion rate, thus suggesting a genuine redshift evolution. Alternatively, we can interpret this result as the presence of an unusually low-energy cutoff $E_{cut}\sim20$ keV on a standard $Γ=1.9$ power-law. We also report on mild indications that HYPERION QSOs show higher soft X-ray emission at 2 keV compared to the UV one at 2500A than expected by lower-z luminous AGN. We speculate that a redshift-dependent coupling between the corona and accretion disc or intrinsically different coronal properties may account for the steep spectral slopes, especially in the presence of powerful winds. The reported slopes, if confirmed at lower luminosities, may have an important impact on future X-ray AGN studies in the early Universe.

description: We demonstrate a compact continuous-wave single-frequency doubly-resonant optical parametric oscillator (DRO) in a double-pass pump configuration with a control of the relative phase between the reflected waves. The nested DRO cavity allows single longitudinal mode operation together with low threshold and high efficiency. Thermal effects are managed by chopping the pump beam, allowing continuous tuning of the emitted wavelength. The infrared idler wave (3200-3800 nm) can be used for gas detection and the threshold pump power is compatible with diode pumping.

Year: 2011

description: Il presente contributo è un'analisi e un commento a I quattrocento colpi di Truffaut. Una delle tematiche di maggior rilievo che emerge dall'analisi è la tematica dello specchio, che viene discussa in termini psicoanalitici sulla scia di quanto Lacan scrive ne Lo stadio dello specchio come formatore della funzione dell'io: la formazione del soggetto passa per il riflesso della sua immagine che trasforma un corpo frammentario in un corpo unitario e identico a se stesso.

description: Hydropower and tourism are interrelated with each other. The construction of hydropower can lead to the development of tourism in that place. The major objective of this study is to identify hydropower tourism in Mirmi and the perceptions of local people about it. This study was conducted among the 162 respondents through convenience sampling technique. This study collected data by using structured questionnaire and key informant interview. The collected data were entered in SPSS and analysed through frequency analysis, pie-chart, cross tabulation and Chi squared test. Perception index was created for this study by using the questionnaire. We have found that tourism has significantly improved after the creation of hydropower and according to many respondents the major attractions of this place is hydropower. People of this place have received both positive and negative impacts from the ongoing tourism activities. People believe that the prospect of tourism in this place is high. Similarly, we have applied chi-square test between perception index of the respondents and socio-economic and demographic status of the respondent and their response on perceived impacts by the hydropower. We found that there is no significant association between socio?economic and demographic status of the respondents but the perception index varied between variables such as male and female and other socio-economic and demographic variables. However there was significant association between perception index and the perceived impacts of the hydropower by the respondents. The prospect of tourism in this place is high. People who have received impacts mostly positive affect their perception towards tourism
Assessing the effects of non-native salmonids on Bull Trout (Salvelinus confluentus) in Alberta’s Rocky Mountain Foothills
Creators: Pallard, Jacqueline L.
Publisher: name: University of Alberta Library
Year: 2022

The rapid decline in global biodiversity threatens the natural resources, food security, health, and livelihoods of current and future generations. Anthropogenic activities, including the introduction of non-native species, habitat fragmentation and alteration, and resource extraction, have exacerbated this decline. One such imperiled species are Bull Trout (Salvelinus confluentus), which have exhibited significant declines throughout their range and are expected to decline by >30% over the next 21 years in Alberta. While their decline is attributed to a myriad of threats, the degree to which non-native fishes contribute to their decline is uncertain. The objective of my thesis was to investigate the effects of Brook Trout (Salvelinus fontinalis) and Brown Trout (Salmo trutta), two non-native salmonids, on the habitat use and dietary niche of Bull Trout. To address the habitat component, I developed a multi-species N-mixture model using in-stream and land use derived characteristics to assess how Brook Trout and Brown Trout affect Bull Trout abundance in relation to habitat factors. I determined that Brook Trout negatively affect Bull Trout abundance when streams are 80%) when in sympatry and the amount of niche overlap does not decrease between allopatry and sympatry. The findings of my thesis suggest that both Brook Trout and Brown Trout interfere with the resource use of Bull Trout, on multiple levels, and provides practical guidelines for limiting future declines.
Infinite Networks, Halting and Local Algorithms

description: The immediate past has witnessed an increased amount of interest in local algorithms, i.e., constant time distributed algorithms. In a recent survey of the topic (Suomela, ACM Computing Surveys, 2013), it is argued that local algorithms provide a natural framework that could be used in order to theoretically control infinite networks in finite time. We study a comprehensive collection of distributed computing models and prove that if infinite networks are included in the class of structures investigated, then every universally halting distributed algorithm is in fact a local algorithm. To contrast this result, we show that if only finite networks are allowed, then even very weak distributed computing models can define nonlocal algorithms that halt everywhere. The investigations in this article continue the studies in the intersection of logic and distributed computing initiated in (Hella et al., PODC 2012) and (Kuusisto, CSL 2013).

description: We identify giant molecular clouds (GMCs) associated with HII regions for a sample of 19 nearby galaxies using catalogs of GMCs and H regions released by the PHANGS-ALMA and PHANGS-MUSE surveys, using the overlap of the CO and Hα emission as the key criterion for physical association. We compare the distributions of GMC and HII region properties for paired and non-paired objects. We investigate correlations between GMC and HII region properties among galaxies and across different galactic environments to determine whether GMCs that are associated with HII regions have significantly distinct physical properties to the parent GMC population. We identify trends between the Hα luminosity of an HII region and the CO peak brightness and the molecular mass of GMCs that we tentatively attribute to a direct physical connection between the matched objects, and which arise independently of underlying environmental variations of GMC and HII region properties within galaxies. The study of the full sample nevertheless hides a large variability galaxy by galaxy. Our results suggests that at the ~100 pc scales accessed by the PHANGS-ALMA and PHANGS-MUSE data, pre-supernova feedback mechanisms in HII regions have a subtle but measurable impact on the properties of the surrounding molecular gas, as inferred from CO observations.

description: Neurons in higher cortical areas, such as the prefrontal cortex, are known to be tuned to a variety of sensory and motor variables. The resulting diversity of neural tuning often obscures the represented information. Here we introduce a novel dimensionality reduction technique, demixed principal component analysis (dPCA), which automatically discovers and highlights the essential features in complex population activities. We reanalyze population data from the prefrontal areas of rats and monkeys performing a variety of working memory and decision-making tasks. In each case, dPCA summarizes the relevant features of the population response in a single figure. The population activity is decomposed into a few demixed components that capture most of the variance in the data and that highlight dynamic tuning of the population to various task parameters, such as stimuli, decisions, rewards, etc. Moreover, dPCA reveals strong, condition-independent components of the population activity that remain unnoticed with conventional approaches.

Open Preservation Foundation products

description: The Open Preservation Foundation (known to most as the OPF) supports and hosts a number of core open source tools and digital preservation initiatives that underpin many digital preservation solutions, activities and workflows. 

Although you may not be aware of it, there are many digital preservation solutions available to the community that have, somewhere under the bonnet, an OPF gismo. The chances are, if you’re running any sort of digital preservation workflow, you’re using something supported by the OPF whether you know it or not.

And that’s a problem. People don’t know.

Open source is not free! It costs an ever-increasing amount to keep these tools alive and up-to date. 

Thanks to our members (and the occasional donation) we have managed to keep the lights on, but it’s tight. We want to do more than just keep things going as they are… And to do that, we need more resources.

If everyone who uses an OPF gismo at their institution (either directly, or indirectly through a third-party product) contributed, we could do so much more.

This poster shows a family tree of OPF products, where they’re used, how often they’re downloaded, and just how much they’re emmeshed into the digital preservation ecosphere.

We want people to know that what they’re doing digital preservation wise is supported by the OPF before we start holding out the hat.

(yes, this is a thinly disguised membership drive and plea for funds)
