description: Counting independent sets on bipartite graphs (#BIS) is considered a canonical counting problem of intermediate approximation complexity. It is conjectured that #BIS neither has an FPRAS nor is as hard as #SAT to approximate. We study #BIS in the general framework of two-state spin systems on bipartite graphs. We define two notions, nearly-independent phase-correlated spins and unary symmetry breaking. We prove that it is #BIS-hard to approximate the partition function of any 2-spin system on bipartite graphs supporting these two notions. As a consequence, we classify the complexity of approximating the partition function of antiferromagnetic 2-spin systems on bounded-degree bipartite graphs.

description: We demonstrate chip-scale sub-Doppler spectroscopy in an integrated and fiber-coupled photonic-metasurface device. The device is a stack of three planar components: a photonic mode expanding grating emitter circuit with a monolithically integrated tilt compensating dielectric metasurface, a microfabricated atomic vapor cell and a mirror. The metasurface photonic circuit efficiently emits a 130 micrometer-wide $1/e^2$ diameter) collimated surface-normal beam with only -6.3 dB loss and couples the reflected beam back into the connecting fiber, requiring no alignment between the stacked components. We develop a simple model based on light propagation through the photonic device to interpret the atomic spectroscopy signals and explain spectral features covering the full Rb hyperfine state manifold.

description: We obtain the next-to-next-to-leading order corrections to transverse-momentum spectra of W, Z and Higgs bosons near the partonic threshold. In the threshold limit, the electroweak boson recoils against a low-mass jet and all radiation is either soft, or collinear to the jet or the beam directions. We extract the virtual corrections from known results for the relevant two-loop four-point amplitudes and combine them with the soft and collinear two-loop functions as defined in Soft-Collinear Effective Theory. We have implemented these results in a public code PeTeR and present numerical results for the threshold resummed cross section of W and Z bosons at next-to-next-to-next-to-leading logarithmic accuracy, matched to next-to-leading fixed-order perturbation theory. The two-loop corrections lead to a moderate increase in the cross section and reduce the scale uncertainty by about a factor of two. The corrections are significantly larger for Higgs production.

description: Water crisis and global warming are two of the biggest challenge of the world. Around 1.1 billion people in the world do not have access to clean water whereas producing water by different purification methods required extensive amount of energy which is generated by burning fossil fuels impacting the environment. This thesis proposes a design of a solar powered reverse osmosis desalination system for a community in Pakistan, which would address the water issue problem for a community in Karachi Pakistan. The design and system sizing of the solar powered reverse osmosis system was done in HOMER Pro followed by techno-economic feasibility analysis of the complete system. The comprehensive dynamic modelling of the system was carried out using the bond graph modelling approach where multidisciplinary systems are modelled using a common bond graph language. 20sim simulation software was used for dynamic analysis of the system. Moreover, a detailed instrumentation system design and control system design was made. After finalization of instrumentation and control design a low-cost, open-source, internet-of-things (IOT) based SCADA system as design was made using field instrument devices and Node-Red. A comprehensive alert system was further integrated with the SCADA design to provide status and updates to the community. Local database was also generated and data was imported by Grafana data analytics tool for making data-driven decisions. A complete laboratory experimental setup was made to verify the SCADA based alert system. Lastly, conclusions are provided based on the research conducted in each section of this thesis, and areas for future research have been identified. This work will provide solution for clean drinking water for a community in Pakistan with robust supervisory control and data acquisition system.

description: AI is anticipated to enhance human decision-making in high-stakes domains like aviation, but adoption is often hindered by challenges such as inappropriate reliance and poor alignment with users' decision-making. Recent research suggests that a core underlying issue is the recommendation-centric design of many AI systems, i.e., they give end-to-end recommendations and ignore the rest of the decision-making process. Alternative support paradigms are rare, and it remains unclear how the few that do exist compare to recommendation-centric support. In this work, we aimed to empirically compare recommendation-centric support to an alternative paradigm, continuous support, in the context of diversions in aviation. We conducted a mixed-methods study with 32 professional pilots in a realistic setting. To ensure the quality of our study scenarios, we conducted a focus group with four additional pilots prior to the study. We found that continuous support can support pilots' decision-making in a forward direction, allowing them to think more beyond the limits of the system and make faster decisions when combined with recommendations, though the forward support can be disrupted. Participants' statements further suggest a shift in design goal away from providing recommendations, to supporting quick information gathering. Our results show ways to design more helpful and effective AI decision support that goes beyond end-to-end recommendations.

description: The purpose of this dissertation was to assist and contribute to the understanding of the origin of the reversible actuation of semicrystalline polymers, specifically focusing on the study of the mechanism behind the thermally triggered two-way shape memory effect (2W-SME) exhibited by such materials. This investigation was performed on high molecular weight crosslinked poly(ε-caprolactone) (PCL) networks and PCL-based urethane derivatives. The thermomechanical investigation of chemically crosslinked PCLs allowed the identification of the main parameters governing the reversibility of the shape-switching transformation of these polymeric networks under constant stress and constant strain conditions. Furthermore, a structural analysis, by means of simultaneous tensile and in-situ SAXS/WAXS tests of these samples, supported the proposal of a two-stepped crystallization model which gives sustain to the observed odd thermomechanical behaviour of chemically crosslinked PCL under constant strain conditions. Finally, the here developed and well characterized thermal-mechanical methodologies proved to be suitable for the characterization of the thermally driven shape-shifting properties of PCL-based semicrystalline materials with varied molecular architectures, including phase-segregated polyurethanes derived from hexamethylene and methylene diphenyl diisocyanate.

description: We analyze electronic excitations (excitations generated by adding or removing one electron) in the bulk of fractional quantum Hall states in Jain sequence states, using composite fermion Chern-Simons field theory. Starting from meanfield approximation in which gauge field fluctuations are neglected, we use symmetry to constrain the possible composite fermion states contributing to electronic Green's function and expect discrete infinitely-sharp peaks in the electronic spectral function. We further consider the electronic excitations in particle-hole conjugate fractional quantum hall states. Gauge field fluctuations play an increasingly important role in the electron spectral function as the filling factor approaches 1/2, and evolve the discrete coherent peaks into a broad continuum even in the absence of impurities. At that limit, we switch to the electron perspective and calculate the electron spectral function via linked cluster approximation from the low to intermediate energy range. Finally, we compare our results with recent experiments.

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: In twisted bilayer semiconductors with arbitrary twisting angles, a chiral excitonic system can arise from the interlayer electron-hole Coulomb exchange interaction (Förster coupling) that hybridizes the anisotropic intralayer excitons from individual layers. We present a general framework for the effective exciton Hamiltonian taking into account the electron-hole Coulomb exchange, using twisted homobilayer systems composed of transition metal dichalcogenides or black phosphorus as examples. We demonstrate that such chiral excitonic systems can feature unconventional Hall (Nernst) effects arising from quantum geometric properties characteristic of the layer hybridized wavefunctions under the chiral symmetry, for example, the time-reversal even layer Hall counter flow and the crossed nonlinear dynamical Hall effect, when mechanical and statistical force (temperature or density gradient) drives the exciton flow.

title: The otolith-isotope method: an opportunity to examine field metabolic rate as an in situ indicator of climate change within and across juvenile Atlantic cod populations (Gadus morhua)
Creators: name: De Groot, Valesca
Publisher: name: Memorial University of Newfoundland
Year: 2023

description: Individual metabolism is a unifying variable in animal ecology, influencing all aspects of performance including growth rate, energetic efficiency, and mortality. As abiotic factors continue to fluctuate due to climate change and anthropogenic disturbance, it is becoming increasingly important to measure an individual's metabolic rate in its natural environment to assess critical energetic tradeoffs. Field metabolic rate (FMR) is the metabolic rate measured from a free-ranging organism, taking into account an individual’s specific dynamic action (SDA), standard metabolic rate (SMR), and activity, yielding a holistic estimate of energy intake and expenditure. Unlike with terrestrial animals, our knowledge of the physiological processes of fishes to date is largely based on extrapolation from observations of historic populations, or from laboratory-based measures of respiratory potential. Here, I describe a newly developed proxy for FMR which pairs the stable isotope composition of the otolith with estimates of oxygen consumption and experienced temperature to yield the full temporal history of the energetic costs associated with environmental change in free-ranging fishes. I outline the opportunities this method presents to make macroecological connections between individual metabolic rate and greater ecosystem interactions, and pair gaps in knowledge in the fields of conservation, ecology, and physiology with important research questions. I also apply the otolith-isotope FMR methodology to juvenile Atlantic cod (Gadus morhua) populations from the Northwest Atlantic, an iconic and economically important species, to examine the relationship between vulnerable early-life stages, decreasing ocean temperature, and energy costs. I compare the FMR-thermal sensitivity and the mean FMR between life history stages within the Newman Sound population (age-0 pulse 1 and pulse 3) and between populations (Newman Sound, Newfoundland; Skagerrak Coast, Norway) to identify pulse- and population-specific behavioural and physiological tradeoffs. I discover pulse-specific differences in mean FMR, and provide insights on the pathways of energy allocation. At the population-level, I recover in situ physiological trends consistent with the metabolic cold adaptation hypothesis, suggesting population-specific thermal adaptation in juvenile Atlantic cod from two populations on opposite sides of the North Atlantic. This research contributes to expanding the current knowledge base of in situ physiological performance for an important fisheries species in the face of changing oceanic conditions. We hope future studies can build upon this research to bridge the gap between data and policy, incorporating field metabolic rate into stock assessments to better inform recruitment forecasting, ensuring a long-term, sustainable Atlantic cod fishery.

description: We prove a version of Bell's Theorem in which the Locality assumption is weakened. We start by assuming theoretical quantum mechanics and weak forms of relativistic causality and of realism (essentially the fact that observable values are well defined independently of whether or not they are measured). Under these hypotheses, we show that only one of the correlation functions that can be formulated in the framework of the usual Bell theorem is unknown. We prove that this unknown function must be differentiable at certain angular configuration points that include the origin. We also prove that, if this correlation is assumed to be twice differentiable at the origin, then we arrive at a version of Bell's theorem. On the one hand, we are showing that any realistic theory of quantum mechanics which incorporates the kinematic aspects of relativity must lead to this type of \emph{rough} correlation function that is once but not twice differentiable. On the other hand, this study brings us a single degree of differentiability away from a relativistic von Neumann no hidden variables theorem.

Gute Renten aus Aktienhand? Die Illusion von der Kapitaldeckung

description: Alterssicherung für Arbeitnehmerinnen und Arbeitnehmer erfolgte in Deutschland jahrzehntelang weitestgehend umlagefinanziert im Rahmen der gesetzlichen Rentenversicherung. Unter Verweis auf höhere Beiträge infolge des demografischen Wandels wurde dieses Systems tiefgreifend reformiert und in seiner Leistungsfähigkeit beschnitten. Entstehende Lücken sollen durch vermehrte private und betriebliche Vorsorge auf freiwilliger Basis geschlossen werden – also verstärkt über die Kapitalmärkte. Entsprechende Angebote wie die kleinteilig ausgerichtete „Riester-Rente“ können dies aus strukturellen Gründen allerdings nicht ausreichend und erst recht nicht flächendeckend leisten. Aus dem Scheitern des bisherigen „Mehrsäulenmodells“ zieht eine politische Mehrheit bislang aber nicht den Schluss, sich wieder von kapitalmarktbasierter Alterssicherung abzuwenden. Stattdessen werden neue Instrumente wie ein Kapitalstock für die Sozialversicherung diskutiert, die insgesamt kollektiveren und verbindlicheren Charakter hätten. Doch trotz struktureller Vorteile könnten auch sie wesentliche Grenzen der sogenannten Kapitaldeckung nicht überwinden: Diese ist letztlich ebenfalls an die volkswirtschaftliche Produktion gekoppelt und kann Wohlstand nicht einfach aus dem Ausland importieren. Von tatsächlicher „Deckung“ kann also keine Rede sein. Begnügt man sich deshalb damit, derartige Vorsorge lediglich als Mittel zur besseren Beteiligung der Versicherten an der Wirtschaftsleistung anzustreben, so ergeben sich gleichwohl noch viele gesellschaftliche, ökonomische und technische Herausforderungen. Insgesamt wird deutlich: Das „Anzapfen“ der Kapitalmärkte zu sozialpolitischen Zwecken ist – sofern überhaupt möglich – keineswegs trivial und unproblematisch. Gerade auch im demografischen Wandel spricht viel dafür, für gute und verlässliche Leistungen auf umlagefinanzierte Alterssicherung mit stabilerem Fundament zu setzen.

We identify the precise axioms defining what we call a "geofibered category" that ensure that such a coherence theorem exists. Our results apply to all the usual sheaf-theoretic contexts of algebraic geometry. The analogous result that would include any other of the six functors remains unknown.

Year: 2023

description: The purpose of this study was to determine the effect the use of the non-intensive care unit confusion assessment method (non-ICU CAM) as an early screening tool for delirium would have on the nursing practice of medical surgical nurses. This quasi-experimental study focused on early screening and prevention training of inpatient nurses caring for adult inpatients to proactively reduce episodes of delirium. The training included an educational video on how to perform the non-ICU CAM assessment, 4 scenarios to test knowledge on scoring patient, and techniques for reducing delirium if patient is positive. After one month of multimodal training for the nursing staff, there was
statistically significant differences between the results of the pre- and post-intervention surveys. Overall, this study determined that the training and use of non-ICU CAM for had a positive impact on the nursing staff in relation to their ability to manage overall identification of delirium in their patients and management of their care. The findings of this study were: the improvement in the nurses’ beliefs within their own practice with a 12.5% increase in their self-efficacy scores, 29.8% improvement in the intention of assessing their patients for delirium, 17.5% improvement in their perceived social norm within their peers, and 11.9% improvement in their attitudes in managing the care of patients with delirium. This study aimed to address two major gaps in what literature suggests as evidence-based practice and what is the current nursing workflows: a gap in nurse knowledge and a gap in clinical practice. This study contributes to the advancement in the practice of nurses outside of the intensive care units in identifying delirium through patient symptom analysis and improve nurses’ coping and management of challenging patient behaviors related to delirium.

description: We present an effective field theory study of radiation and radiation reaction effects for scalar and electromagnetic fields in general spacetime dimensions. Our method unifies the treatment of outgoing radiation and its reaction force within a single action principle. Central ingredients are the field doubling method, which is the classical version of the closed time path formalism and allows a treatment of non-conservative effects within an action, action level matching of system and radiation zones, and the use of fields which are adapted to the enhanced symmetries of each zone. New results include compact expressions for radiative multipoles, radiation, and radiation reaction effective action in any spacetime dimension. We emphasize dimension-dependent features such as the difference between electric and magnetic multipoles in higher dimensions and the temporal non-locality nature of the effective action for odd spacetime dimensions, which is a reflection of indirect propagation ("tail effect") in the full theory. This work generalizes the method and results developed for 4 dimensions in [arXiv:1305.6930], and prepares the way for a treatment of the gravitational case.

description: Offshore wind farms have emerged as a popular renewable energy source that can generate substantial electric power with a low environmental impact. However, integrating these farms into the grid poses significant complexities. To address these issues, optimal-sized energy storage can provide potential solutions and help improve the reliability, efficiency, and flexibility of the grid. Nevertheless, limited studies have attempted to perform energy storage sizing while including design and operations (i.e., control co-design) for offshore wind farms. As a result, the present work develops a control co-design optimization formulation to optimize multiple objectives and identify Pareto optimal solutions. The graph-based optimization framework is proposed to address the complexity of the system, allowing the optimization problem to be decomposed for large power systems. The IEEE-9 bus system is treated as an onshore AC grid with two offshore wind farms connected via a multi-terminal DC grid for our use case. The developed methodology successfully identifies the Pareto front during the control co-design optimization, enabling decision-makers to select the best compromise solution for multiple objectives.

description: The sample frequency spectrum (SFS) is a widely-used summary statistic of genomic variation in a sample of homologous DNA sequences. It provides a highly efficient dimensional reduction of large-scale population genomic data and its mathematical dependence on the underlying population demography is well understood, thus enabling the development of efficient inference algorithms. However, it has been recently shown that very different population demographies can actually generate the same SFS for arbitrarily large sample sizes. Although in principle this nonidentifiability issue poses a thorny challenge to statistical inference, the population size functions involved in the counterexamples are arguably not so biologically realistic. Here, we revisit this problem and examine the identifiability of demographic models under the restriction that the population sizes are piecewise-defined where each piece belongs to some family of biologically-motivated functions. Under this assumption, we prove that the expected SFS of a sample uniquely determines the underlying demographic model, provided that the sample is sufficiently large. We obtain a general bound on the sample size sufficient for identifiability; the bound depends on the number of pieces in the demographic model and also on the type of population size function in each piece. In the cases of piecewise-constant, piecewise-exponential and piecewise-generalized-exponential models, which are often assumed in population genomic inferences, we provide explicit formulas for the bounds as simple functions of the number of pieces. Lastly, we obtain analogous results for the "folded" SFS, which is often used when there is ambiguity as to which allelic type is ancestral. Our results are proved using a generalization of Descartes' rule of signs for polynomials to the Laplace transform of piecewise continuous functions.

description: It remains an open question whether every pure multipartite state that is genuinely entangled is also genuinely nonlocal. Recently, a new general construction of Bell inequalities allowing the detection of genuine multipartite nonlocality (GMNL) in quantum states was proposed in [F. J. Curchod, M. L. Almeida, and A. Acin, New J. Phys. 21, 023016 (2019) with the aim of addressing the above problem. Here we show how, in a simple manner, one can improve this construction to deliver tighter Bell inequalities for detection of GMNL. Remarkably, we then prove one of the improved Bell inequalities to be powerful enough to detect GMNL in every three-qubit genuinely entangled state. We also generalize some of these inequalities to detect not only GMNL but also nonlocality depth in multipartite states and we present a possible way of generalizing them to the case of more outcomes.

title: Autonomous control for on-orbit assembly using artificial potential functions
Creators: name: McQuade, Frank
Publisher: name: University of Glasgow
Year: 1997
Subjects: subject: Aerospace engineering.

description: Current spacecraft mission analysis has highlighted a requirement for the assembly of large structures in Earth Orbit. This thesis investigates an autonomous method of assembly for such large structures. The scheme envisaged is based on Lyapunov's method which is extended to potential function theory. The method forms an analytical solution to the assembly problem by generating high level control commands which are then devolved to individual actuator commands for the assembly vehicles. The application of the method to general assembly problems has allowed the development of a generic global potential function. The application of the global potential function has required the use of a connectivity matrix which contains the information required to assemble the goal structure. Thus, a structure may be modified by altering only the characteristics of the connectivity matrix. The generic assembly method is then applied using a subsumptive type architecture which allows the assembly controller to delegate sub-components of the total structure to secondary controllers. Therefore, the method may then be utilised to construct complex structures, which, when linked to the use of smart components and joints allows the assembly of adaptive structures. These adaptive and variable topology structures which may change their functionality with time may prove useful for future mission applications.

description: The Cs$_2$LiYCl$_6$:Ce (CLYC) elpasolite scintillator is known for its response to fast and thermal neutrons along with good $γ$-ray energy resolution. While the $^{35}$Cl($n,p$) reaction has been identified as a potential means for CLYC-based fast neutron spectroscopy in the absence of time-of-flight (TOF), previous efforts to functionalize CLYC as a fast neutron spectrometer have been thwarted by the inability to isolate proton interactions from $^{6}$Li($n,α$) and $^{35}$Cl($n,α$) signals. This work introduces a new approach to particle discrimination in CLYC for fission spectrum neutrons using a multi-gate charge integration algorithm that provides excellent separation between protons and heavier charged particles. Neutron TOF data were collected using a $^{252}$Cf source, an array of EJ-309 organic liquid scintillators, and a $^6$Li-enriched CLYC scintillator outfitted with fast electronics. Modal waveforms were constructed corresponding to the different reaction channels, revealing significant differences in the pulse characteristics of protons and heavier charged particles at ultrafast, fast, and intermediate time scales. These findings informed the design of a pulse shape discrimination algorithm, which was validated using the TOF data. This study also proposes an iterative subtraction method to mitigate contributions from confounding reaction channels in proton and heavier charged particle pulse height spectra, opening the door for CLYC-based fast neutron and $γ$-ray spectroscopy while preserving sensitivity to thermal neutron capture signals.

description: We report on four different approaches to implementing hash-consing in Coq programs. The use cases include execution inside Coq, or execution of the extracted OCaml code. We explore the different trade-offs between faithful use of pristine extracted code, and code that is fine-tuned to make use of OCaml programming constructs not available in Coq. We discuss the possible consequences in terms of performances and guarantees. We use the running example of binary decision diagrams and then demonstrate the generality of our solutions by applying them to other examples of hash-consed data structures.
Elastocapillary Snapping: Capillarity Induces Snap-Through Instabilities in Small Elastic Beams

description: We report on the capillary-induced snapping of elastic beams. We show that a millimeter-sized water drop gently deposited on a thin buckled polymer strip may trigger an elastocapillary snap-through instability. We investigate experimentally and theoretically the statics and dynamics of this phenomenon and we further demonstrate that snapping can act against gravity, or be induced by soap bubbles on centimeter-sized thin metal strips. We argue that this phenomenon is suitable to miniaturization and design a condensation-induced spin-off version of the experiment involving an hydrophilic strip placed in a steam flow.
Selective Equal-Spin Andreev Reflections Induced by Majorana Fermions

description: In this work, we find that Majorana fermions induce selective equal spin Andreev reflections (SESARs), in which incoming electrons with certain spin polarization in the lead are reflected as counter propagating holes with the same spin. The spin polarization direction of the electrons of this Andreev reflected channel is selected by the Majorana fermions. Moreover, electrons with opposite spin polarization are always reflected as electrons with unchanged spin. As a result, the charge current in the lead is spin-polarized. Therefore, a topological superconductor which supports Majorana fermions can be used as a novel device to create fully spin-polarized currents in paramagnetic leads. We point out that SESARs can also be used to detect Majorana fermions in topological superconductors.

Unconventional superconductivity from electronic dipole fluctuations

description: We study electron-electron Coulomb interactions in electronic systems whose Fermi surfaces possess a finite electric dipole density. Although there is no net dipole moment, we show that electric monopole-dipole interactions can become sufficiently strong in quasi-2D Dirac metals with spin-orbit coupling to induce unconventional odd-parity superconductivity, similar to the Balian-Werthamer state of ${}^{3}$He-B. Hence materials with spin-orbit-induced band inversion, such as the doped topological insulators Bi$_2$Se$_3$, Bi$_2$Te$_3$, and SnTe, are natural candidate materials where our theory could be relevant. We discuss the conditions for an electric dipole density to appear on the Fermi surface and develop the formalism to describe its coupling to the plasmon field which mediates the Coulomb interaction. A mechanism for the enhancement of dipolar coupling is then provided for quasi-2D Dirac systems. Within a large-$N$ renormalization group treatment, we show that the out-of-plane ($z$-axis) dipole coupling is marginally relevant, in contrast to the monopole coupling which is marginally irrelevant. For physically realistic parameters, we find that dipole fluctuations can get sufficiently enhanced to result in Cooper pairing. In addition, we establish that the proposed pairing glue is directly measurable in the $z$-axis optical conductivity.

title: Sensory perception, development, and preservation of undersized American freshwater eel (Anguilla rostrata) as a secondary functional food product
Creators: name: Hamilton, Melissa
Publisher: name: Memorial University of Newfoundland

description: Eels are well-known for being high in dietary lipids, although it is unclear how nutritional quality varies with eel size and ecological location. The nutritional quality of Newfoundland freshwater American eels (Anguilla rostrata) was defined and examined in this study to determine the potential of undersized eels in the manufacture of high-value secondary food products. The findings show that only the habitat location influenced the dietary fatty acid level and undersized eels from Gander, Robinson, and Flat Bay sites had exceptional fatty acid content. These findings suggest that habitat, rather than eel size, is a significant driver in the generation of high-quality dietary lipids in freshwater eels. Highly unsaturated fatty acids are vulnerable to oxidation and generation of toxic compounds when exposed to high temperatures. The use of sous-vide cooking before grilling eel reduced the formation of harmful HCAs, MRCs, and VOCs in Kabayaki. Sous-vide before grilling preserved nutritional value, improved quality and safety, and raised customer appeal. Berry Infused and Regular Kabayaki prepared using the optimized method can be marketed as a ready-to-eat functional food product that offers high overall lipid content and essential fatty acids, reduced toxic MRC, VOCs, and no HCAs, and a wide range of consumer acceptance.
