description: We use topological surgery in dimension four to give sufficient conditions for the zero framed surgery manifold of a 3-component link to be homology cobordant to the 3-torus, which arises from zero framed surgery on the Borromean rings, via a topological homology cobordism preserving the homotopy classes of the meridians. This enables us to give new examples of 3-component links with unknotted components and vanishing pairwise linking numbers, such that any two of these links have homology cobordant zero surgeries in the above sense, but the zero surgery manifolds are not homeomorphic. Moreover the links are not concordant to one another, and in fact they can be chosen to be height n but not height n+1 symmetric grope concordant, for each n which is at least three.

description: Kolmogorov-Arnold networks (KANs) as an alternative to multi-layer perceptrons (MLPs) are a recent development demonstrating strong potential for data-driven modeling. This work applies KANs as the backbone of a neural ordinary differential equation (ODE) framework, generalizing their use to the time-dependent and temporal grid-sensitive cases often seen in dynamical systems and scientific machine learning applications. The proposed KAN-ODEs retain the flexible dynamical system modeling framework of Neural ODEs while leveraging the many benefits of KANs compared to MLPs, including higher accuracy and faster neural scaling, stronger interpretability and generalizability, and lower parameter counts. First, we quantitatively demonstrated these improvements in a comprehensive study of the classical Lotka-Volterra predator-prey model. We then showcased the KAN-ODE framework's ability to learn symbolic source terms and complete solution profiles in higher-complexity and data-lean scenarios including wave propagation and shock formation, the complex Schrödinger equation, and the Allen-Cahn phase separation equation. The successful training of KAN-ODEs, and their improved performance compared to traditional Neural ODEs, implies significant potential in leveraging this novel network architecture in myriad scientific machine learning applications for discovering hidden physics and predicting dynamic evolution.

A numerical lower bound for the spectral radius of random walks on surface groups

Subjects: subject: Probability (math.PR)

description: Estimating numerically the spectral radius of a random walk on a nonamenable graph is complicated, since the cardinality of balls grows exponentially fast with the radius. We propose an algorithm to get a bound from below for this spectral radius in Cayley graphs with finitely many cone types (including for instance hyperbolic groups). In the genus $2$ surface group, it improves by an order of magnitude the previous best bound, due to Bartholdi.

title: Estimating breeding status in Atlantic puffin colonies across Newfoundland: a methodological comparison
Creators: name: Zabala Belenguer, Raul
Publisher: name: Memorial University of Newfoundland
Year: 2023

description: The largest colonies of Atlantic puffins (Fratercula arctica) have been experiencing decades of declining population growth linked to poor breeding performance, particularly in the Eastern Atlantic. These trends have been revealed by the presence of colony-specific monitoring programs. Such data are fragmented and not updated for Newfoundland (Canada) colonies, the largest in the Western Atlantic. Here, I have assessed the burrow laying success, fledging success, and productivity of five colonies at different latitudes in the 2021-2022 breeding season through the establishment of permanent plots. Direct comparisons between current and historical estimates were not possible due to differences in burrow assessment methods. As a remedy, I compared detection probabilities obtained by two different methods, burrowscoping and handgrubbing, and estimated a correction factor to allow for comparisons. Inter-rater reliability of the estimates was also evaluated. My findings show that estimates can be influenced by both data collection method and double-observer, even with experienced individuals. Nevertheless, every breeding parameter remained high in all colonies included in this study, suggesting an overall healthy breeding status in Newfoundland puffin populations, even in those where no historical data are available. This makes Newfoundland colonies the largest puffin aggregation worldwide with no signs of breeding failure in this declining species.
High-efficiency single-photon Fock state production by transitionless quantum driving

description: Single photon source is one of the key devices for optical quantum information processing. Differing from the usual stimulated Raman adiabatic passage to obtain single-photon radiation, here we propose an approach to produce optical Fock state on demand in the usual atom-cavity system by utilizing the technique of transitionless quantum driving. The present proposal effectively suppresses the unwanted but practically unavoidable nonadiabatic transitions in the previous adiabatic schemes. Therefore, the efficiency of Fock state production by the present technique could be significantly high, even in the presence of various atomic and cavity dissipations.
Guided proposals for simulating multi-dimensional diffusion bridges

description: A Monte Carlo method for simulating a multi-dimensional diffusion process conditioned on hitting a fixed point at a fixed future time is developed. Proposals for such diffusion bridges are obtained by superimposing an additional guiding term to the drift of the process under consideration. The guiding term is derived via approximation of the target process by a simpler diffusion processes with known transition densities. Acceptance of a proposal can be determined by computing the likelihood ratio between the proposal and the target bridge, which is derived in closed form. We show under general conditions that the likelihood ratio is well defined and show that a class of proposals with guiding term obtained from linear approximations fall under these conditions.

description: The youngest ($<$50 Myr) planets are vital to understand planet formation and early evolution. The 17 Myr system HIP 67522 is already known to host a giant ($\simeq$10$R_\oplus$) planet on a tight orbit. In the discovery paper, Rizzuto et al. 2020 reported a tentative single transit detection of an additional planet in the system using TESS. Here, we report the discovery of HIP 67522 c which matches with that single transit event. We confirm the signal with ground-based multi-wavelength photometry from Sinistro and MuSCAT4. At a period of 14.33 days, planet c is close to a 2:1 mean motion resonance with b (6.96 days or 2.06:1). The light curve shows distortions during many of the transits, which are consistent with spot crossing events and/or flares. Fewer stellar activity events are seen in the transits of planet b, suggesting that planet c is crossing a more active latitude. Such distortions, combined with systematics in the TESS light curve extraction, likely explain why planet c was previously missed.

description: Water and nutrition are the crucial inputs in the production of high value crops under protected condition, especially the quantity, quality, and timing schedule. A greenhouse experiment on capsicum was taken up for two season during 2020–21 with factorial concept and RCBD design. The experiment was conducted with three levels of automated sensor-based irrigation technology (I1: 75% Available soil moisture (ASM), (I2: 50% ASM and I3: 25% ASM) and 4 levels of fertigation (F1: 75% RDF, F2: 100% Recommended Dose of Fertilizers (RDF), F3: 125% RDF and F4: 150% RDF) with 100% RDF and surface irrigation as control. The results revealed that combination of sensor-based irrigation schedule at 75% ASM with 125% RDF performed well with higher fruit yield (60089 kg ha−1) and was 217.9% higher than the control. Automated scheduling of irrigation at 75% ASM with 150% RDF recorded higher total nutrient uptake, namely, nitrogen (245.30 kg ha−1), phosphorus (105.84 kg ha−1), and potassium (235.33 kg ha−1) than control. It also enhanced economics, namely, net return (US$ 19263 ha−1) and B:C ratio (2.07) and resources use efficiency, namely, nutrient use efficiency (79.5 kg kg−1) and water use efficiency (16.75 kg m−3). Correlation and regression models hypothesize that all the variables are positively correlated with yield at p < .05 and growth variables like nutrient uptake contribute to the fruit yield individually and together increased fruit yield by 97.3% (r2 = 0.973). These results demonstrate that a higher yield is linked to higher nutrient uptake.

description: We present new estimates on the two-dimensional Ginzburg-Landau energy of a type-II superconductor in an applied magnetic field varying between the second and third critical fields. In this regime, superconductivity is restricted to a thin layer along the boundary of the sample. We provide new energy lower bounds, proving that the Ginzburg-Landau energy is determined to leading order by the minimization of a simplified 1D functional in the direction perpendicular to the boundary. Estimates relating the density of the Ginzburg-Landau order parameter to that of the 1D problem follow. In the particular case of a disc sample, a refinement of our method leads to a pointwise estimate on the Ginzburg-Landau order parameter, thereby proving a strong form of uniformity of the surface superconductivity layer, related to a conjecture by Xing-Bin Pan.

description: We investigate the phase structure of the (1+1)-dimensional U(1) gauge-Higgs model with a $θ$ term, where the U(1) gauge action is constructed with Lüscher's admissibility condition. Using the tensor renormalization group, both the complex action problem and topological freezing problem in the standard Monte Carlo simulation are avoided. We find the first-order phase transition with sufficiently large Higgs mass at $θ=π$, where the $\mathbb{Z}_2$ charge conjugation symmetry is spontaneously broken. On the other hand, the symmetry is restored with a sufficiently small mass. We determine the critical endpoint as a function of the Higgs mass parameter and show the critical behavior is in the two-dimensional Ising universality class.

description: Electromagnetic multipole responses are key inputs to model the structure, decay and reaction of atomic nuclei. With the introduction of the finite amplitude method (FAM), large-scale calculations of the nuclear linear response in heavy deformed nuclei have become possible. This work provides a detailed study of multipole responses in actinide nuclei with Skyrme energy density functionals. We quantify both systematic and statistical uncertainties induced by the functional parameterization in FAM calculations. We also extend the FAM formalism to perform blocking calculations with the equal filling approximation for odd-mass and odd-odd nuclei, and analyze the impact of blocking configurations on the response. By examining the entire plutonium isotopic chain from the proton to the neutron dripline, we find a large variability of the response with the neutron number and study how it correlates with the deformation of the nuclear ground state.

description: Measurement estimation bounds for local quantum multiparameter estimation, which provide lower bounds on possible measurement uncertainties, have so far been formulated in two ways: by extending the classical Cramér--Rao bound (e.g., the quantum Cramér--Rao bound and the Nagaoka Cram'er--Rao bound) and by incorporating the parameter estimation framework with the uncertainty principle, as in the Lu--Wang uncertainty relation. In this work, we present a general framework that allows a direct comparison between these different types of estimation limits. Specifically, we compare the attainability of the Nagaoka Cramér--Rao bound and the Lu--Wang uncertainty relation, using analytical and numerical techniques. We show that these two limits can provide different information about the physically attainable precision. We present an example where both limits provide the same attainable precision and an example where the Lu--Wang uncertainty relation is not attainable even for pure states. We further demonstrate that the unattainability in the latter case arises because the figure of merit underpinning the Lu--Wang uncertainty relation (the difference between the quantum and classical Fisher information matrices) does not necessarily agree with the conventionally used figure of merit (mean squared error). The results offer insights into the general attainability and applicability of the Lu--Wang uncertainty relation. Furthermore, our proposed framework for comparing bounds of different types may prove useful in other settings.

description: The first year of observations by the Planck satellite mission shows that the cosmic microwave background (CMB) fluctuations are consistent with gaussian statistics in the primordial perturbations, a key prediction of the simplest models of inflation. However, there are hints of anomalies in the CMB power spectrum and bispectrum. We check for the possibility that some of these anomalous features have a common physical origin in a transient reduction of the inflaton speed of sound. We do this by exploiting predicted correlations between the power spectrum and bispectrum. Our results suggest that current data might already be sensitive enough to detect transient reductions in the speed of sound as mild as a few percent. Since this is a signature of interactions, it opens a new window for the detection of extra degrees of freedom during inflation.

title: On the move and working alone: a study of Newfoundland and Labrador home care workers
Creators: name: Fitzpatrick, Kathleen
Publisher: name: Memorial University of Newfoundland
Year: 2023

description: Home care workers provide paraprofessional services to adults who require additional support to live within their homes. This manuscript dissertation examines Newfoundland and Labrador home care workers' employment-related geographical mobility (mobility to, from, and as part of work) and its consequences for these workers. Guided by insights from feminist political economy, it uses a mixed-methods approach comprising semi-structured interviews, a review of government policies, online collective agreements, census data, and an internet search for the term 'Newfoundland Ladies.' Chapter Two (manuscript #1) documents the dominant patterns of work-related mobility of two groups of home care workers, unionized workers in St. John's, Newfoundland who engage in daily local commutes (to one or more clients daily) and Southwest Newfoundland workers who commute up to thirteen hours for extended periods to work in Nova Scotia to provide live-in care. It examines the drivers and the multiscalar everyday rhythms of these two groups of home care workers and documents ways these mobilities influence the working conditions, the occupational health and safety risks, and the types of precarity associated with each. Chapter Three (manuscript #2) examines how the rhythms of place influence and are influenced by Southwest Newfoundland interprovincial E-RGM rhythms, examines the power relations found in these workers' everyday lives, and highlights mobile place-making. Chapter Four (manuscript #3) explores the complex commuting patterns of unionized home care workers and the corresponding work-related health and safety risks and reviews if the government and home care agency policies and collective agreements mitigate or exacerbate these risks. The dissertation contributes to the home care work and mobility literatures in three ways. First, it brings to the home care literature a mobility lens and offers recommendations to reduce related occupational health and safety risks. Second, it adds to the intersectional rhythmanalysis literature by comparing the rhythms of two forms of employment-related geographical mobility, argues that the rhythms of place are critical in understanding related rhythms, and combines elements of place ballet with intersectional rhythmanalysis to reveal mobile place-making processes. Third, it adds to the mobility literature by comparing interprovincial home care workers to workers engaged in daily local commutes and the accompanying rhythms, working conditions, and health and safety risks.

description: We present a collection of simulations of the Edwards-Anderson lattice spin glass at $T=0$ to elucidate the nature of low-energy excitations over a range of dimensions that reach from physically realizable systems to the mean-field limit. Using heuristic methods, we sample ground states of instances to determine their energies while eliciting excitations through manipulating boundary conditions. We exploit the universality of the phase diagram of bond-diluted lattices to make such a study in higher dimensions computationally feasible. As a result, we obtain a verity of accurate exponents for domain wall stiffness and finite-size corrections that allow us to examine their dimensional behavior and their connection with predictions from mean-field theory. We also provide an experimentally testable prediction for the thermal-to-percolative crossover exponent in dilute lattices Ising spin glasses.

description: Direct loading of lanthanide atoms into magneto-optical traps (MOTs) from a very slow cryogenic buffer gas beam source is achieved, without the need for laser slowing. The beam source has an average forward velocity of 60-70\,m/s and a velocity half-width of ~35 m/s, which allows for direct MOT loading of Yb, Tm, Er and Ho. Residual helium background gas originating from the beam results in a maximum trap lifetime of about 80 ms (with Yb). The addition of a single-frequency slowing laser applied to the Yb in the buffer gas beam increases the number of trapped Yb atoms to 1.3(0.7) x 10^8 with a loading rate of 2.0(1.0) x 10^10 atoms/s. Decay to metastable states is observed for all trapped species and decay rates are measured. Extension of this approach to the loading of molecules into a MOT is discussed.

Using the corner-transfer-matrix renormalization group (CTMRG) method, we demonstrate that the boundary correlation function exhibits power-law decay with quasi-periodic oscillation, while the bulk correlation function always decays exponentially. On the basis of the geometric relation between the bulk correlation path and distance along the outer edge boundary, we find that scaling dimensions for the boundary correlation function can be well explained by the combination of the bulk correlation length and background curvatures inherent to the hyperbolic lattice. We also investigate the cutoff effect of the bond dimension in CTMRG, revealing that the long-distance behavior of the boundary spin correlation is accurately described even with a small bond dimension. In contrast, the sort-distance behavior rapidly loses its accuracy.

description: This poster was presented at the Enhancing Student Learning Through Innovative Scholarship conference in September 2021. It is a collaboration between academic staff and undergraduate students and shares some of our work on supporting the student transition into Higher Education. Abstract: Every year, universities welcome many students who are leaving home for the first time. This transition brings several challenges for students, both academic and pastoral which, without appropriate support, can persist throughout the first year of university and beyond. The 2021-22 academic year will see students arriving at university with a vastly different pre-university experience to those who came before them. They will be facing a whole range of new challenges, some known and some yet unknown to both academic staff and the students themselves. To begin to prepare for this, we surveyed our current Level 3 and 4 students, to identify what they struggled with during their transition to university. The survey was written in collaboration with three current Level 3 and 4 students (authors JH, JH and SV). Here, we present some of the key results from this survey. This student-led approach will identify areas where our current transitions support should be strengthened, allowing us to assemble a 'transitions toolkit', helping our students to get the most out of their university experience.

description: Coupling the fields may lead to the emergence of new phenomena. In the realm of classical fields and nonlinear systems, extensive research has been conducted on their solitary and soliton solutions. In the conducted studies, typically two $ϕ^4$ systems, or two sine-Gordon systems, have been coupled. The sine-Gordon system exhibits diverse solutions, all well-behaved, with its soliton solutions fully understood. On the other hand, the $ϕ^4$ system, which is significant in field theory, has solitary solutions, but these solutions are not solitonic. For example, from a pair of kink and antikink, we cannot construct a bound state; or that after a collision, these two solutions do not revert to their initial status and become disrupted. In this study, we couple a $ϕ^4$ system with a sine-Gordon system to impart stability from the sine-Gordon system to the $ϕ^4$ system. We have demonstrated that for a coupled $ϕ^4$ and sine-Gordon system, this expectation is somewhat met.

description: Let $\ell$ be a prime and let $L/\mathbb{Q}$ be a Galois number field with Galois group isomorphic to $\mathbb{Z}/\ell\mathbb{Z}$. We show that the {\it shape} of $L$ is either $\frac{1}{2}\mathbb{A}_{\ell-1}$ or a fixed sub lattice depending only on $\ell$; such a dichotomy in the value of the shape only depends on the type of ramification of $L$. This work is motivated by a result of Bhargava and Shnidman, and a previous work of the first named author, on the shape of $\mathbb{Z}/3\mathbb{Z}$ number fields.

title: Evaluation of Global Flood Forecasts in Ungauged Catchments

description: Flood forecasting and warning is a non-structural measure which has proved to be efficient and cost effective to minimise negative impacts of flooding (WMO & GWP, 2013) (Mishra and Singh, 2011). Higher spatial and temporal resolution data from earth observations (EO) and the increase in post processing technology has opened opportunities for forecasting floods at continental and global scales (Emerton et al., 2016); Revilla-Romero et al., 2015). This means flood forecasts are available for regions where previously there were no forecasting capabilities from global forecasting systems like the Global Flood Awareness System (GloFAS). A major barrier in using GloFAS in ungauged catchments is a lack of knowledge on how well river flow was predicted for flood events due to a lack of observations. The aim of this thesis is to provide information on GloFAS forecast performance, modelling processes and uncertainty in ungauged catchments. This thesis provides analysis of GloFAS flood forecast performance for the African continent without relying on gauged data and introduces a total of 888 new locations for which performance information is now available. This thesis also provides new methods to assess global flood forecast performance on continental and catchment scales in ungauged catchments, using a combination of flood event databases and inundation data from EO. This combination of data is available globally and these methods could be repeated for any ungauged catchment. This thesis has quantified the performance, model processes and uncertainty of GloFAS flow forecasts in a wide range of ungauged catchments with the objective of unlocking the potential of using GloFAS forecasts in these and other ungauged locations. It is recommended that more research is undertaken in quantitative assessments of forecast performance in ungauged catchments to remove barriers for flood prone regions with no or limited gauged data to benefit from the increasing availability of global flood forecasts.

description: Freshwater ecosystems have been degraded due to intensive freshwater abstraction. Therefore, environmental flow requirements (EFRs) methods have been proposed to maintain healthy rivers and/or restore river flows. In this study, we used the Variable Monthly Flow (VMF) method to calculate the transgression of freshwater planetary boundaries: (1) natural deficits in which flow does not meet EFRs due to climate variability, and (2) anthropogenic deficits caused by water abstractions. The novelty is that we calculated spatially and cumulative monthly water deficits by river types including the frequency, magnitude and causes of environmental flow (EF) deficits (climatic and/or anthropogenic). Water deficit was found to be a regional rather than a global concern (less than 5% of total discharge). The results show that, from 1960 to 2000, perennial rivers with low flow alteration, such as the Amazon, had an EF deficit of 2–12% of the total discharge, and that the climate deficit was responsible for up to 75% of the total deficit. In rivers with high seasonality and high water abstractions such as the Indus, the total deficit represents up to 130% of its total discharge, 85% of which is due to withdrawals. We highlight the need to allocate water to humans and ecosystems sustainably.This article is part of the theme issue 'Drought risk in the Anthropocene'.

description: Der Schock eines neuen Territorialkriegs in Europa und die damit verbundenen Zerstörungen, das Leid und die Flüchtlingsströme sowie der Mut und die Entschlossenheit unzähliger Ukrainer:innen haben in der europäischen Öffentlichkeit deutliche Spuren hinterlassen. Die Europäer wollen eindeutig ihre Solidarität mit der Ukraine zum Ausdruck bringen und wünschen sich, dass die Politiker im Angesicht der Aggression entschlossene Maßnahmen ergreifen. Viele Europäer zeigen sich jedoch auch zunehmend besorgt über ihre Zukunftsaussichten und ihre derzeitige finanzielle Situation.
Diese Studie gibt Aufschluss darüber, wie sich die öffentliche Meinung und Einstellungen in Europa seit Beginn des Krieges in der Ukraine entwickelt haben. Sie basiert auf einer Umfrage, die in zwei Wellen unter fast 12.000 EU-Bürgern zwischen dem 11. und 23. März und dem 3. und 24. Juni 2022 in Form von Online-Interviews durchgeführt wurde.

description: Based on the worm algorithm in the path-integral representation, we propose a general quantum Monte Carlo algorithm suitable for parallelizing on a distributed-memory computer by domain decomposition. Of particular importance is its application to large lattice systems of bosons and spins. A large number of worms are introduced and its population is controlled by a fictitious transverse field. For a benchmark, we study the size-dependence of the Bose-condensation order parameter of the hardcore Bose-Hubbard model with $L\times L\times βt = 10240\times 10240\times 16$, using 3200 computing cores, which shows good parallelization efficiency.

description: Adiabatic quantum computation employs a slow change of a time-dependent control function (or functions) to interpolate between an initial and final Hamiltonian, which helps to keep the system in the instantaneous ground state. When the evolution time is finite, the degree of adiabaticity (quantified in this work as the average ground-state population during evolution) depends on the particulars of a dynamic trajectory associated with a given set of control functions. We use quantum optimal control theory with a composite objective functional to numerically search for controls that achieve the target final state with a high fidelity while simultaneously maximizing the degree of adiabaticity. Exploring properties of optimal adiabatic trajectories in model systems elucidates the dynamic mechanisms that suppress unwanted excitations from the ground state. Specifically, we discover that the use of multiple control functions makes it possible to access a rich set of dynamic trajectories, some of which attain a significantly improved performance (in terms of both fidelity and adiabaticity) through the increase of the energy gap during most of the evolution time.
