Two programs for use of aversive conditioning to manage bold urban coyotes
Creators: Lajeunesse, Gabrielle
Publisher: name: University of Alberta Library
Year: 2023

Human-coyote conflicts are increasing in urban areas, where reports of coyotes approaching, pursuing, or attacking pets and people have become more prevalent. Aversive conditioning is increasingly being advocated as a non-lethal method to reduce conflicts with bold coyotes, but it has not been much studied and there are few guidelines for its implementation. In this thesis, I quantified the responses by coyotes and public reporting to aversive conditioning as a management tool for bold, urban coyotes in each of two aversive conditioning programs conducted in Alberta, Canada, between 2018 and 2022. I first evaluated the use of high intensity aversive conditioning conducted by a team of contracted wildlife professionals and their trained dogs in the City of Calgary, Alberta, between 2018 and 2021. Aversive conditioning treatments consisted of using dogs to attract coyotes from cover and paintball guns to fire chalk balls at coyotes. Most (607/736, 82.47%) coyotes retreated quickly from aversive conditioning. The likelihood of coyote retreat increased with the number of previous aversive conditioning engagements at the site and when high intensity aversive conditioning treatments (i.e., those where dogs were used and shots were fired) had been applied prior to the event being investigated. Retreat likelihood declined with the number of days since the last aversive conditioning engagement.I then implemented and assessed a community-based hazing program conducted in Edmonton, Alberta, in 2021 and 2022. Trained volunteers patrolled their residential neighborhoods while searching for coyotes and coyote attractants. When coyotes were observed, volunteers determined their boldness and, when appropriate, hazed coyotes by running towards them while shouting and throwing weighted tennis balls in their direction. Throughout 1,598 patrols, volunteers observed coyotes 175 times, and conducted hazing on 23 occasions. Almost all coyotes (22/23, 95.65%) retreated from hazing. I found little evidence that this treatment affected subsequent coyote boldness or the frequency or timing of subsequent coyote reports, but the low frequency of hazing events limited the power of these tests.  My results suggest that both low and high-intensity hazing cause coyotes to leave the immediate area, but only the higher intensity hazing conducted in Calgary demonstrated measurable changes in subsequent behaviour by coyotes or reporting characteristics by people. High-intensity hazing may be necessary to change the behaviour of bold animals, but low-intensity hazing may deter coyotes during conflict situations while increasing the sense of security in residential areas experienced by people.

description: We give a combinatorial description of the Legendrian contact homology algebra associated to a Legendrian link in $S^1\times S^2$ or any connected sum $\#^k(S^1\times S^2)$, viewed as the contact boundary of the Weinstein manifold obtained by attaching 1-handles to the 4-ball. In view of the surgery formula for symplectic homology, this gives a combinatorial description of the symplectic homology of any 4-dimensional Weinstein manifold (and of the linearized contact homology of its boundary). We also study examples and discuss the invariance of the Legendrian homology algebra under deformations, from both the combinatorial and the analytical perspectives.

description: The prosperous development of both hardware and algorithms for quantum computing (QC) potentially prompts a paradigm shift in scientific computing in various fields. As an increasingly active topic in QC, the variational quantum algorithm (VQA) leads a promising direction for solving partial differential equations on Noisy Intermediate Scale Quantum (NISQ) devices. Although a clear perspective on the advantages of QC over classical computing techniques for specific mathematical and physical problems exists, applications of QC in computational fluid dynamics to solve practical flow problems, though promising, are still in an early stage of development. To explore QC in practical simulation of flow problems, this work applies a variational hybrid quantum-classical algorithm, namely the variational quantum linear solver (VQLS), to resolve the heat conduction equation through finite difference discretization of the Laplacian operator. Details of VQLS implementation are discussed by various test instances of linear systems. Finally, the successful statevector simulations of the heat conduction equation in one and two dimensions demonstrate the validity of the present algorithm by proof-of-concept results. In addition, the heuristic scaling for the heat conduction problem indicates that the time complexity of the present approach is logarithmically dependent on the precision ε and linearly dependent on the number of qubits n.

description: The purpose of this paper is to determine all maximal graded subalgebras of the four infinite series of finite-dimensional graded Lie superalgebras of odd Cartan type over an algebraically closed field of characteristic $p>3$. All maximal graded subalgebras consist of three types (\MyRoman{1}), (\MyRoman{2}) and (\MyRoman{3}). Maximal graded subalgebras of type (\MyRoman{3}) fall into reducible maximal graded subalgebras and irreducible maximal graded subalgebras. In this paper we classify maximal graded subalgebras of types (\MyRoman{1}), (\MyRoman{2}) and reducible maximal g raded subalgebras.The classification of irreducible maximal graded subalgebras is reduced to that of the irreducible maximal subalgebras of the classical Lie superalgebra $\mathfrak{p}(n)$.

Commonsense Knowledge Generation and Analysis using Deep Learning Models
Creators: Rezaei Sarchoghaei, Navid

Year: 2023

There has been a renewed interest in commonsense as a stepping stone toward achieving human-level intelligence. By digesting enormous amounts of data in different forms, such as visual, lingual, and sensory, humans are able to create a world model for themselves. It is hypothesized that this knowledge is the basis for commonsense, which can be defined as a collection of models of the world that know the plausibility of entities or interactions. This commonsensical world model helps humans learn new skills with very few trials, as they can predict the consequences of actions and plan and reason for the next steps.

In our work, we explore and experiment with how we can generate commonsense knowledge and how it can ultimately benefit deep learning models to gain commonsense. We also analyze the weaknesses of large language models (LLMs) in a commonsense context and provide solutions to improve LLMs in commonsensical tasks.

Inspired by how toddlers learn about their environment, we first introduce a methodology to generate commonsense knowledge using only visual input. We use knowledge graphs as the preferred method of data storage, as they are easy to access and require low time complexity to expand. We further expand the knowledge stored with plausibility weights of triples and contextual information.

As linguistics is an important next step in a toddler’s mental model of the world, we experiment with transformer-based language models to expand the vision-based commonsense even further. Through experiments with language models, we observe that larger language models, trained in an unsupervised fashion, have more embedded commonsense than their smaller counterparts. Symbolic and vetted storage of commonsense knowledge from different sources can improve commonsense capabilities in smaller language models. Resource-restricted use cases, such as smartphones or self-driving cars, benefit from offline smaller language models.

During our research, we noticed the high cost of human annotations to gather human commonsense datasets used to train language models. As a by-product of our research, we proposed a model-agnostic prompt technique to reduce costly human textual annotations for fine-tuning language models.

Lastly, we demonstrate that out-of-ordinary questions can throw the LLMs off guard. We illustrate how \textit{negated complementary} questions adversely affect the model responses. We propose a model-agnostic methodology to improve the performance in \textit{negated complementary} scenarios. Our method outperforms few-shot generation from GPT-3 (by more than 11 points) and, more importantly, highlights the significance of studying the response of large language models in different commonsensical scenarios.

description: Electromagnetic Star-Planet Interaction (SPI) describes the phenomenon, when a planet couples to its host star via electromagnetic forces. Alfvén waves can establish such a coupling by forming Alfvén wings. SPI allows phenomena that we do not know from the Solar System. Wing-wing interaction is such an example, where the Alfvén wings of two planets merge and interact non-linearly. In this paper we focus on the effects that SPI has on other planets and the stellar wind. First, we analyse the different wave structures connected to SPI. The second part then investigates wing-wing interaction. Our study applies a magnetohydrodynamic model to describe a stellar system with multiple possible planets. As an example, we chose TRAPPIST-1 and its two innermost planets. We extended the PLUTO code to simulate collisions between atmospheric neutral particles and plasma ions. Neutral gas clouds imitate the planets and move through the simulation domain. That allows the simulation of fully time-dependent stellar systems. We analysed the wave structures, which result from the interaction between stellar wind and TRAPPIST-1 b. The inward going wave structure is an Alfvén wing. The outward going part of the interaction consists of an Alfvén wing, slow mode waves, the planetary wake and a slow shock. We quantified the strength of the respective wave perturbations at the outer planets to be on the order of 10\% to 40\% of the local background values of thermal, magnetic and dynamic pressure. Wing-wing interaction occurs due to the relative position of two planets during their conjunction and shows three phases. First there is an initial, non-linear intensification of the Poynting flux by $20\%$, an intermediate phase with reduced Poynting flux and a third phase when the Alfvén wing of planet c goes through planet b's wave structures with another intensification of the Poynting flux.

description: Two objects can be distinguished if they have different measurable properties. Thus, distinguishability depends on the Physics of the objects. In considering graphs, we revisit the Ising model as a framework to define physically meaningful spectral invariants. In this context, we introduce a family of refinements of the classical spectrum and consider the quantum partition function. We demonstrate that the energy spectrum of the quantum Ising Hamiltonian is a stronger invariant than the classical one without refinements. For the purpose of implementing the related physical systems, we perform experiments on a programmable annealer with superconducting flux technology. Departing from the paradigm of adiabatic computation, we take advantage of a noisy evolution of the device to generate statistics of low energy states. The graphs considered in the experiments have the same classical partition functions, but different quantum spectra. The data obtained from the annealer distinguish non-isomorphic graphs via information contained in the classical refinements of the functions but not via the differences in the quantum spectra.

description: We analyze the physical content of squeezed bispectra involving long-wavelength tensor perturbations, showing that these modes cannot be gauged away, except for the exact (unphysical) limit of infinite wavelength, $k = 0$. This result has a direct implication on the validity of the Maldacena consistency relation, respected by a subclass of inflationary models. Consequently, in the squeezed limit, as in the case of the scalar-scalar-scalar bispectrum, squeezed mixed correlators could be observed by future experiments, remaining a key channel to study Early Universe physics and discriminate among different models of inflation.

description: We prove that the functor of noncommutative deformations of every flipping or flopping irreducible rational curve in a 3-fold is representable, and hence associate to every such curve a noncommutative deformation algebra. This new invariant extends and unifies known invariants for flopping curves in 3-folds, such as the width of Reid, and the bidegree of the normal bundle. It also applies in the settings of flips and singular schemes. We show that the noncommutative deformation algebra is finite dimensional, and give a new way of obtaining the commutative deformations of the curve, allowing us to make explicit calculations of these deformations for certain (-3,1)-curves. We then show how our new invariant also controls the homological algebra of flops. For any flopping curve in a projective 3-fold with only Gorenstein terminal singularities, we construct an autoequivalence of the derived category of the 3-fold by twisting around a universal family over the noncommutative deformation algebra, and prove that this autoequivalence is an inverse of Bridgeland's flop-flop functor. This demonstrates that it is strictly necessary to consider noncommutative deformations of curves in order to understand the derived autoequivalences of a 3-fold, and thus the Bridgeland stability manifold.

description: We report the thermodynamic properties studied by thermal expansion, magnetostriction, magnetisation, and specific heat measurements as well as the low-energy magnetic excitations of \mto\ and investigate how magneto-elastic coupling and magnetic anisotropy affect the evolution of long-range order and the magnetic phase diagram. Specifically, we utilise high-resolution capacitance dilatometry and antiferromagnetic resonance (AFMR) studies by means of high-frequency electron spin resonance (HF-ESR) spectroscopy. The role of anisotropy is reflected by spin-reorientation at $B_{\rm{SF}}$~$\simeq 6$~T and a corresponding sign change in $\partial T_{\rm N}/\partial B$. Analysis of the AFMR modes enables us to establish the zero-field excitation gap $Δ$ as well as its temperature dependence. We derive the effective anisotropy field $B_\mathrm{A} = 0.16(1)$~T which predominately originates from out-of-plane nearest-neighbour dipole-dipole interactions. Despite the nearly fully quenched orbital moment, our data show pronounced thermal expansion and magnetostriction anomalies at $T_{\rm N}$ and $B_{\rm{SF}}$ , respectively, which allows the experimental determination of sizable uniaxial pressure dependencies, i.e., $\partial B_{\rm SF}/\partial p_{\rm c} = -0.20(2)$~T/GPa, $\partial T_{\rm N}/ \partial p_b = 0.69(12)$~K/GPa, and $\partial T_{\rm N}/ \partial p_c = -2.0(4)$~K/GPa. Notably, short-range magnetic order appears up to at least 3$T_{\rm N}$ , as indicated by anisotropic lattice distortion, the violation of a constant Grüneisen behavior, and the presence of local magnetic fields detected by HF-ESR.

description: We consider the non-degenerate second-order parabolic partial differential equations of non-divergence form with bounded measurable coefficients (not necessary continuous). Under some assumptions it is known that the fundamental solution to the equations exists uniquely, has the Gaussian bounds and is locally Hölder continuous. In the present paper, we concern the Gaussian bounds and the lower bound of the index of the Hölder continuity with respect to the initial point. We use the pinned diffusion processes for the probabilistic representation of the fundamental solutions and apply the coupling method to obtain the regularity of them. Under some assumptions weaker than the Hölder continuity of the coefficients, we obtain the Gaussian bounds and the $(1-\varepsilon)$-Hölder continuity of the fundamental solution in the initial point.

Firm Emergence and Strategy: The Impact of Institutional Background
Creators: Owusu, Joseph D
Publisher: name: University of Alberta Library
Year: 2023

This dissertation extends our understanding of the relationship between entrepreneurial teams and entrepreneurial outcomes. Using a sample of 260 nascent family ventures, I look at the impact of entrepreneurial team composition on important entrepreneurial milestones. I examine two specific measures of entrepreneurial outcomes: the chances of entrepreneurial groups establishing new family firms and their propensity to engage in exploration and exploitation. Drawing from the institutional logics perspective and building on the entrepreneurial team literature, I introduce the concept of institutional background- a team demographic characteristic- as an important dimension of team composition. I argue that institutional background provides richer measures of mechanisms and processes that affect founding team cognition, values, perceptions and, consequently, entrepreneurial outcomes. I explore my arguments using two studies. In the first study, I focus on entrepreneurial groups attempting to launch new family-owned manufacturing firms. I investigate how their institutional backgrounds impact their chances of getting their organizations started. By focusing on the not-yet fully established organization, my findings provide a fresh perspective to our understanding of the emergence of family firms. In the second study, I explore how the logic imprinted at founding continues to shape organizational practices—the propensity to engage in exploration and exploitation. The second study challenges and extends current work on exploration, exploitation, and organizational ambidexterity by showing that founders’ institutional backgrounds constrain strategic choices. By connecting decisions on explorative and exploitative behaviour to founders’ institutional background, this study provides an alternative to managerial ‘discretion’ and ‘ability’ to manage exploration and exploitation. Overall, this dissertation takes another step toward opening the black box of how entrepreneurial teams impact entrepreneurial outcomes.

What Does it Mean to be an Ally in Indigenous Healthcare?
Creators: Bruno, Margaux
Publisher: name: University of Alberta Library
Year: 2023

Allyship is loosely defined as the actions of an individual who works to advance the interests of marginalized groups in which they are not a member. Allyship in the healthcare field is under-studied yet is increasingly an area of interest, given Indigenous health outcomes throughout the world, and especially in countries with colonial histories, are generally poorer than the mainstream population.

This qualitative research study took place with healthcare providers in and around the Edmonton area that are community-identified allies providing care for Indigenous patients. Due to the impacts of the COVID-19 pandemic, much of the research took place virtually. Qualitative description methodology was utilized, and data was generated through semi-structured interviews with allies. The interviews were transcribed verbatim and then coded using thematic analysis. To ensure validity, generalizability, and reliability of the data, verification strategies were used throughout this study.

The results indicate that allies share common characteristics and a desire to learn and continue to improve care, while also appreciating the importance of relationships and the need for advocacy towards a systemic overhaul of all social institutions. This thesis not only demonstrates the importance of allyship in healthcare, but also shows that applying the concept of allyship to healthcare relies on a great deal of independent self-guided and ongoing work on the part of healthcare providers.

description: We revisit the search for heavy neutral leptons with the Big European Bubble Chamber in the 1982 proton beam dump experiment at CERN, focussing on those heavier than the kaon and mixing only with the tau neutrino, as these are far less constrained than their counterparts with smaller mass or other mixings. Recasting the previous search in terms of this model and including additional production and decay channels yields the strongest bounds to date, up to the tau mass. This applies also to our updated bounds on the mixing of heavy neutral leptons with the electron neutrino.

Specific reduction in complex I of the mitochondrial electron transport system in long-lived seed beetles
Creators: Mast, Heather
Publisher: name: University of Alberta Library
Year: 2023

Background: Mitochondrial dysfunction is a recognized hallmark of aging that is also directly or indirectly connected to practically all the other hallmarks of aging. As a result, mitochondrial dysfunction seems to be an important regulator of lifespan. Many studies provide evidence of lifespan extension following a decrease in mitochondrial complexes, but few studies have actually measured and compared integrated mitochondrial function. Additionally, most studies on longevity are on a limited number of animal models, such as Drosophila and Caenorhabditis elegans.

Methods: Here, we measured integrated mitochondrial function in the seed beetle, Acanthoscelides obtectus. This animal model has been selected for early (E) and late (L) reproduction for nearly four decades and over 250 generations, leading to two lines of the same animal species, each with a very different longevity (7 days in E line, 12-14 days in L line). First, we determined mitochondrial content and used high-resolution respirometry to measure the NADH, Succinate, and Proline dehydrogenase pathways and complex IV in short-lived (E line) and long-lived (L line) beetles of both sexes and at 3 timepoints (days 1, 5, and 8). Second, we determined complex I, complex II, and complex IV’s control over combined NADH+Succinate+Proline flux in male beetles at days 1 and 5. Lastly, we tested fatty acid oxidation.

Results: The NADH pathway’s contribution to maximal flux was lower and the Succinate pathway’s contribution was higher in L line beetles, mostly at days 1 and 5, suggesting a link between early differences in mitochondrial function and longevity. Control by complex I was also stronger and complex IV had a higher excess capacity in L line beetles at day 1 of age. Male beetles tended to have more longevity-linked differences compared to females. There were no differences in proline and fatty acid metabolisms between the beetle selection lines.

Conclusion: The combined reduction in the NADH pathway and increased control of mitochondrial respiration by complex I suggest that complex I contributes to the lifespan extension seen in L line beetles. The opposite seems to be true for E line beetles. This work, comparing different selection lines within the same animal species, reinforces the involvement of mitochondrial dysfunction in lifespan while also evaluating sex differences and additional metabolic pathways.

Design of Low-Profile Multi-Band Microwave Antennas and Components Using Metamaterial-Based Electromagnetic Bandgap Structures
Creators: Smyth, Braden P.
Publisher: name: University of Alberta Library
Year: 2023

This thesis investigates applications of metamaterial-based electromagnetic bandgap structures, or MTM-EBGs. MTM-EBGs are uniplanar, compact, and often fully printable, making them ideal candidates for integration into planar topologies. This differs from many other metamaterial-based structures that have been proposed in the last couple of decades, many of which have shown great potential but have suffered from drawbacks including difficult integration into existing structures, poor operating characteristics, and expensive fabrication. Along with its useful physical and electrical properties, the recent development of MTM-EBG theory based on multiconductor transmission line techniques has rendered its properties predictable and designable, and this presents an excellent opportunity to fully explore how they can be used to improve performance and reduce the size of commonly used microstrip-based structures. In particular, embedding MTM-EBG unit cells directly into the metallic features of microstrip-based circuit components and antennas is an efficient way to produce multi-band operation without taking up any extra circuit board space. A general approach is taken that further allows the same technology to be used in a multitude of different applications. This is demonstrated with the design of many different circuit components, including dual- and tri-band microstrip stub filters, dual- and tri-band matching networks for arbitrary impedances, and a dual-band Wilkinson power divider. There are diverse uses in antenna applications as well; a dual-band antenna is first presented, followed by a simultaneously dual-band and dual-polarized antenna, as well as a GPS antenna with increased bandwidth. A tunable version of the dual-band dual-polarized antenna demonstrates further possibilities of what can be achieved with the MTM-EBG. Most devices were fabricated for comparison to simulation and excellent agreement is consistently seen between both sets of results, further suggesting that the MTM-EBG is a versatile and extremely useful tool for creating the next generation of miniaturized and multi-functional microwave systems.

description: Multiwavelength variability of blazars offers indirect insight into their powerful engines and on the mechanisms through which energy is propagated from the centre down the jet. The BL Lac object Mkn 421 is a TeV emitter, a bright blazar at all wavelengths, and therefore an excellent target for variability studies. Mkn 421 was observed by INTEGRAL and Fermi-LAT in an active state on 16-21 April 2013. Well sampled optical, soft, and hard X-ray light curves show the presence of two flares. The average flux in the 20-100 keV range is 9.1e-11 erg/s/cm2 (~4.5 mCrab) and the nuclear average apparent magnitude, corrected for Galactic extinction, is V ~12.2. In the time-resolved X-ray spectra (3.5-60 keV), which are described by broken power laws and, marginally better, by log-parabolic laws, we see a hardening that correlates with flux increase, as expected in refreshed energy injections in a population of electrons that later cool via synchrotron radiation. The hardness ratios between the JEM-X fluxes in two different bands and between the JEM-X and IBIS/ISGRI fluxes confirm this trend. During the observation, the variability level increases monotonically from the optical to the hard X-rays, while the large LAT errors do not allow a significant assessment of the MeV-GeV variability. The cross-correlation analysis during the onset of the most prominent flare suggests a monotonically increasing delay of the lower frequency emission with respect to that at higher frequency, with a maximum time-lag of about 70 minutes, that is however not well constrained. The spectral energy distributions from the optical to the TeV domain are satisfactorily described by homogeneous models of blazar emission based on synchrotron radiation and synchrotron self-Compton scattering, except in the state corresponding to the LAT softest spectrum and highest flux.

Understanding the Nurses Perspective of Citizen Science and Climate Action
Creators: Rempel, Hannah

The issue of climate change is one that threatens the foundation of human health and existence. As health professionals and leaders, nurses have been trained to advocate for health, communicate risks, and manage complex systems. This makes nurses ideal candidates to raise awareness, educate and carry it out for climate change and climate action. Citizen science might be a way that fits for nurses to engage in climate action personally and/or within their communities. This qualitative descriptive study used semi-structured interviews to understand nurse’s perspective on climate change, citizen science and climate action. Twelve nurses from the interior of British Columbia (BC) were interviewed using a semi structured interview guide. Thematic analysis was employed. Data analysis yielded four themes to describe nurses’ perspective on citizen science and climate action: health impacts; climate knowledge, beliefs, and language; climate action; and system influences. Nurses explained their personal and professional experiences living through forest fires where the threat of evacuation was ever present. These experiences contributed to their beliefs about climate change and how to contribute both personally and in their workplace to be part of climate action. These findings provide an initial understanding about how nurses think about citizen science and how they might engage in climate action to support our first health system, our ecological system.

description: We use matrix product techniques to investigate the performance of two algorithms for obtaining the ground state of a quantum many-body Hamiltonian $H = H_A + H_B$ in infinite systems. The first algorithm is a generalization of the quantum approximate optimization algorithm (QAOA) and uses a quantum computer to evolve an initial product state into an approximation of the ground state of $H$, by alternating between $H_A$ and $H_B$. We show for the 1D quantum Ising model that the accuracy in representing a gapped ground state improves exponentially with the number of alternations. The second algorithm is the variational imaginary time ansatz (VITA), which uses a classical computer to simulate the ground state via alternating imaginary time steps with $H_A$ and $H_B$. We find for the 1D quantum Ising model that an accurate approximation to the ground state is obtained with a total imaginary time $τ$ that grows only logarithmically with the inverse energy gap $1/ Δ$ of $H$. This is much faster than imaginary time evolution by $H$, which would require $τ\sim 1/ Δ$.

description: In this work, we analyze the first whispering gallery mode resonator (WGMR) made from monocrystalline yttrium lithium fluoride (YLF). The disc-shaped resonator is fabricated using single-point diamond turning and exhibits a high intrinsic quality factor ($Q$) on the order of $10^9$. Moreover, we employ a novel method based on microscopic imaging of Newton's rings through the back of a trapezoidal prism. This method can be used to evanescently couple light in to a WGMR and monitor the separation between the cavity and the coupling prism. Accurately calibrating the distance between a coupling prism and a WGMR is desirable as it can be used to improve experimental control and conditions, i.e., accurate coupler gap calibration can aid in tuning into desired coupling regimes and can be used to avoid potential damage caused by collisions between the coupling prism and the WGMR. Here, we use two different trapezoidal prisms together with the high-$Q$ YLF WGMR to demonstrate and discuss this method.

description: This paper analyzes distributed control protocols for first- and second-order networked dynamical systems. We propose a class of nonlinear consensus controllers where the input of each agent can be written as a product of a nonlinear gain, and a sum of nonlinear interaction functions. By using integral Lyapunov functions, we prove the stability of the proposed control protocols, and explicitly characterize the equilibrium set. We also propose a distributed proportional-integral (PI) controller for networked dynamical systems. The PI controllers successfully attenuate constant disturbances in the network. We prove that agents with single-integrator dynamics are stable for any integral gain, and give an explicit tight upper bound on the integral gain for when the system is stable for agents with double-integrator dynamics. Throughout the paper we highlight some possible applications of the proposed controllers by realistic simulations of autonomous satellites, power systems and building temperature control.

description: In vacuo cryogenic environments are ideal for applications requiring both low temperatures and extremely low particle densities. This enables reaching long storage and coherence times, for example, in ion traps, essential requirements for experiments with highly charged ions, quantum computation, and optical clocks. We have developed a novel cryostat continuously refrigerated with a pulse-tube cryocooler and providing the lowest vibration level reported for such a closed-cycle system with 1 W cooling power for a <5 K experiment. A decoupling system suppresses vibrations from the cryocooler by three orders of magnitude down to a level of 10 nm peak amplitudes in the horizontal plane. Heat loads of about 40 W (at 45 K) and 1 W (at 4 K) are transferred from an experimental chamber, mounted on an optical table, to the cryocooler through a vacuum-insulated massive 120 kg inertial copper pendulum. The 1.4 m long pendulum allows installation of the cryocooler in a separate, acoustically isolated machine room. At the experimental chamber, we measured the residual vibrations using an interferometric setup. The positioning of the 4 K elements is reproduced to better than a few micrometer after a full thermal cycle to room temperature. Extreme high vacuum on the 10−15 mbar level is achieved. In collaboration with the Max-Planck-Institut für Kernphysik, such a setup is now in operation at the Physikalisch-Technische Bundesanstalt for a next-generation optical clock experiment using highly charged ions.
On complete positivity, Markovianity, and the quantum data-processing inequality, in the presence of initial system-environment correlations

description: We show that complete positivity is not only sufficient but also necessary for the validity of the quantum data-processing inequality. As a consequence, the reduced dynamics of a quantum system are completely positive, even in the presence of initial correlations with its surrounding environment, if and only if such correlations do not allow any anomalous backward flow of information from the environment to the system. Our approach provides an intuitive information-theoretic framework to unify and extend a number of previous results.

description: The paper gives a precise asymptotic relation between higher order logarithmic difference and logarithmic derivatives for meromorphic functions with order strictly less then one. This allows us to formulate a useful Wiman-Valiron type estimate for logarithmic difference of meromorphic functions of small order. We then apply this estimate to prove a classical analogue of Valiron about entire solutions to linear differential equations with polynomials coefficients for linear difference equations.
