description: Projection-based Controllers (PBCs) are currently gaining traction in both scientific and engineering communities. In PBCs, the input-output signals of the controller are kept in sector-bounded sets by means of projection. In this paper, we will show how this projection operation can be used to induce useful passivity or general dissipativity properties on broad classes of (unprojected) nonlinear controllers that otherwise would not have these properties. The induced dissipativity properties of PBC will be exploited to guarantee asymptotic stability of negative feedback interconnections of passive nonlinear plants and suitably designed PBC, under mild conditions. Proper generalizations to so-called $(q,s,r)$-dissipativity will be presented as well. For illustrating the effectiveness of PBC control design via these passivity-based techniques, two numerical examples are provided.

description: Dynamic mode decomposition (DMD) is a recently developed tool for the analysis of the behavior of complex dynamical systems. In this paper, we will propose an extension of DMD that exploits low-rank tensor decompositions of potentially high-dimensional data sets to compute the corresponding DMD modes and eigenvalues. The goal is to reduce the computational complexity and also the amount of memory required to store the data in order to mitigate the curse of dimensionality. The efficiency of these tensor-based methods will be illustrated with the aid of several different fluid dynamics problems such as the von Kármán vortex street and the simulation of two merging vortices.

description: We apply the adaptive variational quantum imaginary time evolution (AVQITE) method to prepare ground states of one-dimensional spin $S=1$ models. We compare different spin-to-qubit encodings (standard binary, Gray, unary, and multiplet) with regard to the performance and quantum resource cost of the algorithm. Using statevector simulations we study two well-known spin-1 models: the Blume-Capel model of transverse-field Ising spins with single-ion anisotropy, and the XXZ model with single-ion anisotropy. We consider system sizes of up to $20$ qubits, which corresponds to spin-$1$ chains up to length $10$. We determine the dependence of the number of CNOT gates in the AVQITE state preparation circuit on the encoding, the initial state, and the choice of operator pool in the adaptive method. Independent on the choice of encoding, we find that the CNOT gate count scales cubically with the number of spins for the Blume-Capel model and quartically for the anistropic XXZ model. However, the multiplet and Gray encodings present smaller prefactors in the scaling relations. These results provide useful insights for the implementation of AVQITE on quantum hardware.

Hyper prolific authors in environmental sciences: Productivity pays

Subjects: Other environmental sciences not elsewhere classified

description: Prof. Brian Nosek wrote that there is no cost to getting things wrong, the cost is not getting them published. Recent years have seen the rise of hyper prolific scientists who publish an abnormally high volume of scientific articles, frequently at a rate significantly higher than their fellows. Although there is a general view that productivity is a favourable trait, overly productive researchers may raise questions about the quantity, calibre, and impact of their work. To be aware of the potential risks and unfavourable effects of generating an overly large number of publications, it is crucial to carefully assess the work of scientists who are hyper prolific. Since there hasn't been any research on this topic on environmental sciences, this study performed a comprehensive survey of 931,027 articles published in 2013-2022 in Environmental Sciences journals to to investigate the very prolific authors in this field. The findings show that some authors are extremely prolific, publishing an average of 50–100 publications each year. Furthermore, a tight network of scientists with a remarkable number of highly cited papers is revealed by network analysis. In order to ensure that the process of publishing a paper is carried out honestly and that vested interests do not jeopardize the advancement of knowledge, it is decided that the scientific community has to adopt ethical norms and procedures regarding the number of publications. Publications should encourage openness, transparency, and reproducibility.
Placing a small-scale Vertical Axis Wind Turbine on roof-top corner of a  building
Creators: Rezaei, Farshad
Paraschivoiu, Marius
Publisher: name: University of Alberta Library
Year: 2022

The current study demonstrates the very high performance of Vertical-Axis Wind Turbine (VAWT) on the roof-top corner of a building using Computational Fluid Dynamics (CFD). A small-scale VAWT with high rotational velocity is validated using the SST k-ω turbulence model. It is shown that this turbulence model can predict the flow field around and the performance of the turbine accurately in comparison with experimental results. By locating the turbine on the corner of the building and having the wind at an angle of 45° with respect to the face of the building, it is found that the power coefficient of the turbine increases significantly at higher values of Tip Speed Ratios (TSRs). Nevertheless, it is found that by doubling the Aspect ratio (AR) of the turbine, its performance decreased.

description: Cascade failures in power grids occur when the failure of one component or subsystem causes a chain reaction of failures in other components or subsystems, ultimately leading to a widespread blackout or outage. Controlling cascade failures on power grids is important for many reasons like economic impact, national security, public safety and even rippled effects like troubling transportation systems. Monitoring the networks on node level has been suggested by many, either controlling all nodes of a network or by subsets. This study identifies sensitive graph elements of the weighted European power-grids (from 2016, 2022) by two different methods. Bridges are determined between communities and "weak" nodes are selected by the lowest local synchronization of the swing equation. In the latter case we add bypasses of the same number as the bridges at weak nodes, and we compare the synchronization, cascade failure behavior by the dynamical improvement with the purely topological changes. The results are also compared if bridges are removed from networks, which results in a case similar to islanding, and with the addition of links at randomly selected places. Bypassing was found to improve synchronization the best, while the average cascade sizes are the lowest with bridge additions. However, for very large or small global couplings these network changes do not help, they seem to be useful near the synchronization transition region, where self-organization drives the power-grid. Thus, we provide a demonstration for the Braess' Paradox on continent-sized power grid simulations and uncover the limitations of this phenomenon. We also determine the cascade size distributions and justify the power-law tails near the transition point on these grids.

description: We prove a strong factorization property of interpolation Macdonald polynomials when $q$ tends to $1$. As a consequence, we show that Macdonald polynomials have a strong factorization property when $q$ tends to $1$, which was posed as an open question in our previous paper with Féray. Furthermore, we introduce multivariate $q,t$-Kostka numbers and we show that they are polynomials in $q,t$ with integer coefficients by using the strong factorization property of Macdonald polynomials. We conjecture that multivariate $q,t$-Kostka numbers are in fact polynomials in $q,t$ with nonnegative integer coefficients, which generalizes the celebrated Macdonald's positivity conjecture.

description: Localized spins of single atoms adsorbed on surfaces have been proposed as building blocks for spintronics and quantum computation devices. However, identifying a way to achieve current-induced switching of spins with very low dissipation is an outstanding challenge with regard to practical applications. Here, we show that the indirect exchange interaction between spin impurities can be controlled by a dissipationless supercurrent. All that is required is a conventional superconductor and two spin impurities placed on its surface. No triplet Cooper pairs or exotic material choices are needed. This finding provides a new and accessible way to achieve the long-standing goal of supercurrent-induced spin switching.

Second, we propose χ 2-tests for detecting cross-sectional and serial dependence in the VaR-forecasts. Moreover, we combine our new backtests with a test of unconditional coverage to yield two new backtests of multivariate conditional coverage. In all cases, a bootstrap approximation is possible, but not mandatory in terms of empirical size and power.

Exploring Chaos and Ergodic behavior of an Inductorless Circuit driven by Stochastic Parameters

description: There exist extensive studies on periodic and random perturbations of various continuous maps investigating their dynamics. This paper presents a random piecewise smooth map derived from a simple inductor-less switching circuit. The bifurcation parameter is bounded and randomly selected from a stationary distribution. Due to the stochasticity inherent in either the parameter values or the state variable, the time evolution of the state variable cannot be predicted at a specific time instant. We observe that the state variable exhibits completely ergodic behavior when the minimum value of the parameter is 2.0. However, the ensemble average of the state variable converges to a fixed value. For parameter values ranging from 2.0 to 3.5, the system demonstrates nonchaotic behavior, and the absolute value of the Lyapunov exponent increases monotonically with the asymmetry (ap) of the distribution from which the bifurcation parameter values are sampled. We determine the probability density function of the random map and verify its invariance under any initial condition. The most noteworthy result is the disappearance of chaotic behavior when the lower range of the distribution is varied while maintaining a fixed upper threshold for a particular distribution, even though the nonrandom map exhibits an array of periodic and chaotic behaviors within that range.

description: We calculate and present an analytic form of the magneto-optical conductivity for the gapped low-energy Kane model in two and three dimensions separately. The two-dimensional case maps onto the $α$-$\mathcal{T}_3$ model at a particular value of $α=1/\sqrt{3}$. In two dimensions, two chiral sectors exist, between which there are no optically activated transitions. In three dimensions, the extra dimension of dispersion mixes the two sectors so that intra- and inter-sector transitions can occur. The latter type of transition can be separated out via circular polarizations of light and shows a distinct signature in the transverse conductivity.

description: Omentin-1 is a novel adipokine that has a pivotal role in modulating the insulin sensitivity, immunity and inflammation. The current study was conducted to evaluate the serum omentin-1 level in hepatitis C virus (HCV) infected patients, with or without type 2 diabetes, and to investigate its correlation with liver function parameters and insulin resistance. Methods: Eighty subjects were enrolled in this study divided into four groups: chronic HCV infected patients (n=20), chronic hepatitis C patients with concomitant type 2 diabetes (n=18), type 2 diabetic patients (n=22) and 20 healthy controls. Serum omentin-1 levels were assessed using enzyme-linked immunosorbent assay (ELISA). Fasting blood glucose, insulin levels, and liver parameters including aminotrans ferases (ALT and AST) were determined. Results: Serum omentin-1 levels were significantly elevated in HCV infected patients compared to all other groups. Omentin-1 levels were positively correlated with AST and ALT levels (r =0.43, p< 0.001; r =0.423, p<0.001, respectively). Additionally, a significant negative correlation was found between omentin-1 and both fasting insulin levels and homeostasis model assessment of insulin resistance (HOMA-IR) (r = -0.238, p< 0.05; r = -0.277, p<0.05, respectively). Furthermore, fasting blood glucose, HbA1c and HOMA-β were negatively correlated to serum omentin-1 levels however these correlations were not statistically significant. Conclusion: Serum omentin-1 level is elevated in HCV infected patients and is positively associated with liver enzymes AST and ALT. This suggested that omentin-1 may be implicated in the pathogenesis of hepatitis C and its metabolic complications. However its role needs to be elucidated by further studies.

Reducing the overall mine-water consumption is a necessity in moving toward a more sustainable mining industry in Canada. Water treatment is a key requirement to achieve this  goal. This study numerically investigates the dynamics of a decantation process as a technique to recycle and reuse mine-water.  A three-dimensional mathematical model that considers the conservation of mass and momentum has been derived, validated,  and implemented to simulate the turbulent two-phase flow inside a decantation tank. The framework of the validated model has  been extended to examine the effect of various design and operating parameters on the efficiency of a full-scale decantation tank.  The results compare the efficiency of multiple designs of the decantation tank in terms of the overflow water quality. The results  indicate that the efficiency of the decantation tank increases with inner surface area, where a plain decanter with a tangential inlet pipe has the highest efficiency.

CFD Study of the aerodynamic performance of a Vertical Axis Wind Turbine in  the wake of another turbine
Creators: Belabes, Belkacem

Publisher: name: University of Alberta Library
Year: 2022

An increased interest in Vertical Axis Wind Turbines (VAWTs) has been seen recently due to their ability to be placed closer together. Although individual vertical axis wind turbines (VAWTs) have lower efficiency than horizontal axis wind turbines (HAWTs), they may have a significant advantage when placed on a wind farm. The wake interaction between turbines is one of the main characteristics of flows around multiple wind turbines that affect the performance of VAWTs. This effect has not been thoroughly researched. The capability of CFD to accurately simulate the impact of the wake on the performance of different VAWT is explored in this paper. The effect of the wake on a downstream turbine is quite important as it affects the performance. A configuration of two H-Darieus wind turbines is modeled using RANS equations solved within the commercial tool STAR CCM+. The study of the wake generated by the first wind turbine and its effect on the wind turbine downstream with different distances is the focus of the current research. The space between the two rotors varies from 2.5 to 40 times the turbine's diameter.

description: The aim of this study was to investigate the antioxidant activity of the methanolic extracts of Filipendula hexapetala Gilib. aerial parts (FHA) and roots (FHR) and their potential in different model systems, as well as antimicrobial activity. According to this, a number of assays were employed to evaluate the antioxidant and antimicrobial potential of F. hexapetala extracts. In addition, the antioxidant activity assays in different model systems were carried out, as well as pH, thermal and gastrointestinal stability studies. The phenolic compounds contents in FHA and FHR were also determined. The results showed that F. hexapetala extracts had considerable antioxidant activity in vitro and a great stability in different conditions. The extracts exhibited antimicrobial activity against most of the tested bacterial and fungal species. Also, the extracts contain high level of phenolic compounds, especially aerial parts extract.

description: How do we capture the breadth of behavior in animal movement, from rapid body twitches to aging? Using high-resolution videos of the nematode worm $C. elegans$, we show that a single dynamics connects posture-scale fluctuations with trajectory diffusion, and longer-lived behavioral states. We take short posture sequences as an instantaneous behavioral measure, fixing the sequence length for maximal prediction. Within the space of posture sequences we construct a fine-scale, maximum entropy partition so that transitions among microstates define a high-fidelity Markov model, which we also use as a means of principled coarse-graining. We translate these dynamics into movement using resistive force theory, capturing the statistical properties of foraging trajectories. Predictive across scales, we leverage the longest-lived eigenvectors of the inferred Markov chain to perform a top-down subdivision of the worm's foraging behavior, revealing both "runs-and-pirouettes" as well as previously uncharacterized finer-scale behaviors. We use our model to investigate the relevance of these fine-scale behaviors for foraging success, recovering a trade-off between local and global search strategies.

description: We show that spin squeezing criteria commonly used for entanglement detection can be erroneous, if the probe is not symmetric. We then derive a lower bound on squeezing for separable states in spin systems probed asymmetrically. Using this we further develop a procedure that allows us to verify the degree of entanglement of a quantum state in the spin system. Finally, we apply our method for entanglement verification to existing experimental data, and use it to prove the existence of tri-partite entanglement in a spin squeezed atomic ensemble.

description: We study the effects of a vertical electric field on the electronic band structure and transport in multilayer phosphorene and its nanoribbons. In phosphorene, at a critical value of the vertical electric field ($E_c$), the band gap closes and the band structure undergoes a massive-to-massless Dirac fermion transition along the armchair direction. This transition is observable in quantum Hall measurements, as the power-law dependence of the Landau-level energy on the magnetic field $B$ goes from $\sim (n+1/2)B$ below $E_c$, to $\sim [(n+1/2)B]^{2/3}$ at $E_c$, to $\sim [(n+1/2)B]^{1/2}$ above $E_c$. In multilayer phosphorene nanoribbons (PNRs), the vertical electric field can be employed to manipulate the midgap energy bands that are associated with edge states, thereby giving rise to new device functionalities. We propose a dual-edge-gate PNR structure that works as a quantum switch.

description: We investigate the physical conditions of the gas, atomic and molecular, in the filaments in the context of Photo-Dissociation Regions (PDRs) using the KOSMA-PDR mode of clumpy clouds. We also compare the [CII] vs. [NII] integrated intensity predictions in Abel et al. 2005 for HII regions and adjacent PDRs in the Galactic disk, and check for their applicability under the extreme physical conditions present in the GC. Our preliminary results show that observed integrated intensities are well reproduced by the PDR model. The gas is exposed to a relatively low Far-UV field between 10^2 - 10^3 Draine fields. The total volume hydrogen density is well constrained between 10^4 - 10^5 cm^-3. The hydrogen ionization rate due to cosmic-rays varies between 10^-15 and 4x10^-15 s^-1, with the highest value ~ 10^-14 s^-1 found towards G0.07+0.04. Our results show that the line-of-sight contribution to the total distance of the filaments to the Arches Cluster is not negligible. The spatial distribution of the [CII]/[NII] ratio shows that the integrated intensity ratios are fairly homogeneously distributed for values below 10 in energy units. Calculations including variation on the [C/N] abundance ratio show that tight constraints on this ratio are needed to reproduce the observations.

description: In quantum optics, measurement statistics -- for example, photocounting statistics -- are considered nonclassical if they cannot be reproduced with statistical mixtures of classical radiation fields. We have formulated a necessary and sufficient condition for such nonclassicality. This condition is given by a set of inequalities that tightly bound the convex set of probabilities associated with classical electromagnetic radiation. Analytical forms for full sets and subsets of these inequalities are obtained for important cases of realistic photocounting measurements and unbalanced homodyne detection. As an example, we consider photocounting statistics of phase-squeezed coherent states. Contrary to a common intuition, the analysis developed here reveals distinct nonclassical properties of these statistics that can be experimentally corroborated with minimal resources.

description: We derive the first systematic observational constraints on reheating in models of inflation where an additional light scalar field contributes to primordial density perturbations and affects the expansion history during reheating. This encompasses the original curvaton model but also covers a larger class of scenarios. We find that, compared to the single-field case, lower values of the energy density at the end of inflation and of the reheating temperature are preferred when an additional scalar field is introduced. For instance, if inflation is driven by a quartic potential, which is one of the most favoured models when a light scalar field is added, the upper bound $T_{\mathrm{reh}}<5\times 10^{4}\,\mathrm{GeV}$ on the reheating temperature $T_{\mathrm{reh}}$ is derived, and the implications of this value on post-inflationary physics are discussed. The information gained about reheating is also quantified and it is found that it remains modest in plateau inflation (though still larger than in the single-field version of the model) but can become substantial in quartic inflation. The role played by the vev of the additional scalar field at the end of inflation is highlighted, and opens interesting possibilities for exploring stochastic inflation effects that could determine its distribution.

Measurement of the proton structure function F 2 at low Q 2 at HERA

description: A measurement of the inclusive deep inelastic positron proton scattering cross-section at low momentum transfers squared Q2 between 0:2 GeV2 and 3:5 GeV2 and values of Bjorken x down to 3 ¢ 10¡5 is presented. Based on this the proton structure function F2, parameterising the quark composition of the proton, is extracted. Measurements at these low values of Q2 are particularly interesting since perturbative calculations based on Quantum Chromodynamics, the theory of the strong interaction, can no longer be performed and only phenomenological models are able to describe the proton structure. Experimentally this transition region can be accessed by shifting the interaction point of positrons and protons into the direction of the incoming proton. This possibility has been exploited in the year 2000 during a special running period of the HERA collider. The present analysis is based on data recorded with the H1 detector at that time. Compared to a similar data taking period in 1995 the statistical error of the data sample is smaller by a factor of two. Due to a detailed investigation of the systematic uncertainties a®ecting the measurement it has been possible to reduce the total error by almost the same amount. The improved precision should allow for a better constraint of the available phenomenological models.
description: In der vorliegenden Arbeit wird eine Messung des inklusiven Wirkungsquerschnitts der tie¯nelastischen Positron-Proton-Streuung bei kleinen Viererimpulsübertragsquadraten Q2 zwischen 0:2 GeV2 und 3:5 GeV2 vorgestellt. Der minimal erreichbare Wert der Bjorken Skalenvariablen x beträgt dabei 3 ¢ 10¡5. Mit Hilfe der Messergebnisse wird die Protonstrukturfunktion F2 bestimmt, die den Quarkinhalt des Protons parametrisiert. Der analysierte Teil des Phasenraums ist von besonderem Interesse, da bei hinreichend kleinen Werten von Q2 störungstheoretische Vorhersagen im Rahmen der Quantenchromodynamik, der Theorie der starkenWechselwirkung, versagen und phänomenologische Modelle zur Beschreibung der Protonstruktur herangezogen werden müssen. Um diesen Übergangsbereich experimentell zugänglich zu machen, wurde der Wechselwirkungspunkt von Positronen und Protonen am HERA-Beschleuniger während einer speziellen Datennahmeperiode im Jahr 2000 in Richtung des einlaufenden Protons verschoben. Die mit dem H1-Detektor in diesem Zeitraum aufgezeichneten Daten bilden die Grundlage der durchgeführten Messung. Der statistische Fehler des Datensatzes ist um einen Faktor zwei kleiner als für eine entsprechende Datennahmeperiode im Jahr 1995. Aufgrund einer detaillierten Untersuchung der systematischen Unsicherheiten konnte der totale Messfehler um nahezu den gleichen Wert verringert werden. Die Messergebnisse sollen dazu beitragen, die freien Parameter der verfügbaren phänomenologischen Modelle mit höherer Präzision zu bestimmen.

description: A family of closed manifolds is called cohomologically rigid if a cohomology ring isomorphism implies a diffeomorphism for any two manifolds in the family. We establish cohomological rigidity for large families of 3-dimensional and 6-dimensional manifolds defined by 3-dimensional polytopes. We consider the class P of 3-dimensional combinatorial simple polytopes, different from a tetrahedron, whose facets do not form 3- and 4-belts. This class includes mathematical fullerenes, i.e. simple 3-polytopes with only 5-gonal and 6-gonal facets. By a theorem of Pogorelov, any polytope from P admits a right-angled realisation in Lobachevsky 3-space, which is unique up to isometry. Our families of smooth manifolds are associated with polytopes from the class P. The first family consists of 3-dimensional small covers of polytopes from P, or hyperbolic 3-manifolds of Loebell type. The second family consists of 6-dimensional quasitoric manifolds over polytopes from P. Our main result is that both families are cohomologically rigid, i.e. two manifolds M and M' from either of the families are diffeomorphic if and only if their cohomology rings are isomorphic. We also prove that if M and M' are diffeomorphic, then their corresponding polytopes are combinatorially equivalent. These results are intertwined with the classical subjects of geometry and topology, such as combinatorics of 3-polytopes, the Four Colour Theorem, aspherical manifolds, diffeomorphism classification of 6-manifolds and invariance of Pontryagin classes. The proofs use techniques of toric topology.
