description: In this poster I present the first high-spectral resolution (R=115,000 for the optical, and R=50,000 for the NIR) unbiased survey of 25 Herbig Ae/Be stars performed with the instruments HARPS and GIANO at TNG.
 This is the first survey observing simultaneously the full spectral range from 3,800A to 24,500A at such high spectral resolution, representing an unique opportunity to constrain the properties of the gas in the inner disk regions of Herbig AeBe protoplanetary disks, and to probe the physical processes driving this emission. In this poster, I present our results on the Herbig Ae star HD141569 as an example of the potential of this survey. It is a A0 star with 1.9 solar masses at 110 pc distance (V=7.1) with virtually no IR-excess. This source shows bright emission in the [O I] 6300A line, as well as in the Hydrogen Balmer, Paschen, and Brackett series. Our high spectral resolution data show that these lines are double peaked with a clear Keplerian pattern. This allows us for the first time to constrain the physical properties and line emitting region of the gas in the inner disk, and give important clues about its origin in a systematic and homogenous way for a large sample of sources.

description: We find the numbers of $3 \times 3$ magic, semimagic, and magilatin squares, as functions either of the magic sum or of an upper bound on the entries in the square. Our results on magic and semimagic squares differ from previous ones in that we require the entries in the square to be distinct from each other and we derive our results not by \emph{ad hoc} reasoning but from the general geometric and algebraic method of our paper "An enumerative geometry for magic and magilatin labellings". Here we illustrate that method with a detailed analysis of $3\times3$ squares.

description: We study an inverse boundary value problem on the determination of principal order coefficients in isotropic nonautonomous heat flows stated as follows; given a medium, and in the absence of heat sources and sinks, can the time-dependent thermal conductivity and volumetric heat capacity of the medium be uniquely determined from the Cauchy data of temperature and heat flux measurements on its boundary? We prove uniqueness in all dimensions under an assumption on the thermal diffusivity of the medium, which is defined as the ratio of the thermal conductivity and volumetric heat capacity. As a corollary of our result for isotropic media, we also obtain a uniqueness result, up to a natural gauge, in two-dimensional anisotropic media. Our assumption on the thermal diffusivity is related to construction of certain families of exponential solutions to the heat equation.

description: When subjected to electro-mechanical loading, ferroelectrics see their polarization evolve through the nucleation and evolution of domains. Existing mesoscale phase-field models for ferroelectrics are typically based on a gradient-descent law for the evolution of the order parameter. While this implicitly assumes that domain walls evolve with linear kinetics, experiments instead indicate that domain wall kinetics is nonlinear. This, in turn, is an important feature for the modeling of rate-dependent effects in polarization switching. We propose a new multiple-phase-field model for ferroelectrics, which permits domain wall motion with nonlinear kinetics, with applications in other solid-solid phase transformation problems. By means of analytical traveling wave solutions, we characterize the interfacial properties (energy and width) and the interface kinetics of straight domain walls, as furnished by the general kinetics model, and compare them to those of the classical Allen--Cahn model. We show that the proposed model propagates domain walls with arbitrarily chosen nonlinear kinetic relations, which can be tuned to differ for the different types of domain walls in accordance with experimental evidence.

description: When network and graph theory are used in the study of complex systems, a typically finite set of nodes of the network under consideration is frequently either explicitly or implicitly considered representative of a much larger finite or infinite region or set of objects of interest. The selection procedure, e.g., formation of a subset or some kind of discretization or aggregation, typically results in individual nodes of the studied network representing quite differently sized parts of the domain of interest. This heterogeneity may induce substantial bias and artifacts in derived network statistics. To avoid this bias, we propose an axiomatic scheme based on the idea of node splitting invariance to derive consistently weighted variants of various commonly used statistical network measures. The practical relevance and applicability of our approach is demonstrated for a number of example networks from different fields of research, and is shown to be of fundamental importance in particular in the study of spatially embedded functional networks derived from time series as studied in, e.g., neuroscience and climatology.

description: Acoustic scene classification is a process of characterizing and classifying the environments from sound recordings. The first step is to generate features (representations) from the recorded sound and then classify the background environments. However, different kinds of representations have dramatic effects on the accuracy of the classification. In this paper, we explored the three such representations on classification accuracy using neural networks. We investigated the spectrograms, MFCCs, and embeddings representations using different CNN networks and autoencoders. Our dataset consists of sounds from three settings of indoors and outdoors environments - thus the dataset contains sound from six different kinds of environments. We found that the spectrogram representation has the highest classification accuracy while MFCC has the lowest classification accuracy. We reported our findings, insights as well as some guidelines to achieve better accuracy for environment classification using sounds.

description: A sample of 129 unresolved radio sources with ultrahigh linear polarization (>30 per cent) has been selected from the NRAO VLA Sky Survey. Such high average linear polarization is unusual in extragalactic sources. Higher resolution Australia Telescope Compact Array and Very Large Array observations confirm the high average polarization but find that most of these sources are extended. The Sloan Digital Sky Survey spectroscopy, where available, shows that the optical counterparts are elliptical galaxies with no detectable emission lines. The optical spectra, radio luminosity, linear size and spectral index of these sources are typical of radio-loud active galactic nuclei. Galaxy counts within a 1 Mpc radius of the radio sources show that these highly polarized sources are in environments similar to their low polarization (<2 per cent) counterparts. Similarly, the line-of-sight environments of the ultrahigh polarization sources are on average indistinguishable from those of the low-polarization sources. We conclude that the extraordinarily high average polarization must be due to intrinsic properties of the sources, such as an extremely ordered source magnetic field, low internal thermal plasma density or a preferential orientation of the source magnetic field perpendicular to the line of sight.

One-shot Federated Learning without Server-side Training

description: Federated Learning (FL) has recently made significant progress as a new machine learning paradigm for privacy protection. Due to the high communication cost of traditional FL, one-shot federated learning is gaining popularity as a way to reduce communication cost between clients and the server. Most of the existing one-shot FL methods are based on Knowledge Distillation; however, {distillation based approach requires an extra training phase and depends on publicly available data sets or generated pseudo samples.} In this work, we consider a novel and challenging cross-silo setting: performing a single round of parameter aggregation on the local models without server-side training. In this setting, we propose an effective algorithm for Model Aggregation via Exploring Common Harmonized Optima (MA-Echo), which iteratively updates the parameters of all local models to bring them close to a common low-loss area on the loss surface, without harming performance on their own data sets at the same time. Compared to the existing methods, MA-Echo can work well even in extremely non-identical data distribution settings where the support categories of each local model have no overlapped labels with those of the others. We conduct extensive experiments on two popular image classification data sets to compare the proposed method with existing methods and demonstrate the effectiveness of MA-Echo, which clearly outperforms the state-of-the-arts.

title: Glycaemic index and glycaemic response: exploring an optimum profile for cognitive function across the day
Creators: name: Grout, Matthew
Publisher: name: University of Reading
Year: 2020

description: Foods associated with a more favourable glycaemic response have been linked with cognitive benefits in acute settings in both the clinically healthy and those with type 2 diabetes. However, the current evidence is largely limited to examination of the effects of a single meal, particularly breakfast. Given that the daily human dietary pattern consists of multiple meals, the single meal paradigm fails to provide information about the glycaemic response and cognitive performance throughout the day. In addition, the glycaemic response following a meal has been shown to influence postprandial glycaemia and cognitive performance following a subsequent meal, which further illustrates the need to extend the current single meal investigation to a multiple meal testing paradigm. This thesis, therefore, aimed to investigate the relationship between the glycaemic response, cognitive performance and subjective mood across three consecutive meals in both clinically healthy and T2DM populations. Initially, two novel test meal profiles were designed using the glycaemic index concept with the aim of producing significantly different glycaemic profiles across the day; specifically, a Favourable (FGP) and Unfavourable (UGP) Glycaemic Profile. The two glycaemic conditions were then implemented in two randomised cross-over intervention studies in clinically healthy (n=40) and T2DM populations (n=25) to examine their effects on cognitive performance and subjective mood. Finally, a post-hoc analysis was performed to compare the glycaemic and cognitive outcome responses of the clinically healthy and T2DM populations. The FGP meals consistently produced a lower glycaemic response across the day in all samples. The clinically healthy population did not gain cognitive benefits from either condition, whereas the T2DM population displayed sustained cognitive performance during the FGP condition, particularly during the period after breakfast consumption. In addition, poor glucose regulators (defined via a glucose composite score) displayed worse cognitive performance than good glucose regulators within each population under an increased cognitive load. Finally, the glycaemic conditions had minimal impact on subjective mood. Taken together, these findings indicate that a more favourable glycaemic response profile over the course of several meals is associated with better cognitive performance in those with poorer glucose tolerance (i.e. T2DM) compared to an unfavourable glycaemic response profile. Longitudinal investigation of glycaemic control and cognitive performance in those with T2DM, using the multiple meal profiles developed in this thesis is suggested as future research. This would provide data on the extent, if any, of whether a long-term favourable glycaemic profile is associated with attenuation of cognitive impairment observed in those with T2DM.

description: Multi-wavelength observations are mandatory to understand the physical properties of astrophysical sources. In this paper we use observations in the far infrared to radio range to derive the spectral energy distribution (SED) of the Carina nebula. To do this, we carefully subtract the irregularly varying diffuse emission from the Galactic plane, which can be of the order of 10 of the nebula flux at these wavelengths. We find that the far infrared SED can be modeled as emission from a dust population with a single temperature T_d=(34.5^{+2.0}_{-1.8}), and with a spectral index of emissivity alpha=-1.37^{+0.09}_{-0.08}. We also find a total infrared luminosity of the Nebula of (7.4^{+2.5}_{-1.4})x10^6 L_{\odot} and, assuming a single temperature of the dust, a mass of the dust of (9500^{+4600}_{-3500})M_\odot.

description: We consider a supersymmetric SU(5) model where two neutrino masses are obtained via a mixed type I+III seesaw mechanism induced by the component fields of a single SU(5) adjoint. We have analyzed the phenomenology of the model paying particular attention to flavour violating processes and dark matter relic density, assuming universal boundary conditions. We have found that, for a seesaw scale larger than $10^{12÷13}$ GeV, BR$(μ\to e γ)$ is in the reach of the MEG experiment in sizable regions of the parameter space. On the other side, current bounds on it force BR$(τ\to μγ)$ to be well below the reach of forthcoming experiments, rendering thus the model disprovable if a positive signal is found. The same bounds still allow for a sizable positive contribution to $ε_K$, while the CP violation in the $B_s$ mixing turns out to be too small to account for the di-muon anomaly reported by the D0 collaboration. Finally, the regions where the neutralino relic density is within the WMAP bounds can be strongly modified with respect to the constrained MSSM case. In particular, a peculiar coannihilation region, bounded from above, can be realized, which allows us to put an upper bound on the dark matter mass for certain set-ups of the parameters.

description: A key component of the phase diagram of many iron-based superconductors and electron-doped cuprates is believed to be a quantum critical point (QCP), delineating the onset of antiferromagnetic spin-density wave order in a quasi-two-dimensional metal. The universality class of this QCP is believed to play a fundamental role in the description of the proximate non-Fermi liquid and superconducting phases. A minimal model for this transition is the $\mathrm{O}(3)$ spin-fermion model. Despite many efforts, a definitive characterization of its universal properties is still lacking. Here, we numerically study the $\mathrm{O}(3)$ spin-fermion model and extract the scaling exponents and functional form of the static and zero-momentum dynamical spin susceptibility. We do this using a Hybrid Monte Carlo (HMC) algorithm with a novel auto-tuning procedure, which allows us to study unprecedentedly large systems of $80 \times 80$ sites. We find a strong violation of the Hertz-Millis form, contrary to all previous results. Furthermore, the form that we do observe provides good evidence that the universal scaling is actually governed by the analytically tractable fixed point discovered near perfect ``hot-spot'" nesting, even for a larger nesting window. Our predictions can be directly tested with neutron scattering. Additionally, the HMC method we introduce is generic and can be used to study other fermionic models of quantum criticality, where there is a strong need to simulate large systems.

description: We present internal velocity dispersions and precise radial velocities for 200 globular clusters (GCs) in M31 that are derived using new high-resolution spectra from MMT/Hectochelle. Of these, 163 also have King model structural parameters that allow us to estimate their mass-to-light ratios. This is, by far, the largest such dataset available for any galaxy, including the Milky Way. These data strongly confirm earlier suggestions that the optical and near-infrared mass-to-light ratios of M31 GCs decline with increasing metallicity. This behavior is the opposite of that predicted by stellar population models for a standard initial mass function. We show that this phenomenon does not appear to be caused by standard dynamical evolution. A shallower mass function for metal-rich GCs (with dN/dM ~ M^-0.8 to M^-1.3 below one solar mass) can explain the bulk of extant observations. We also observe a consistent, monotonic correlation between mass-to-light ratio and cluster mass. This correlation, in contrast to the correlation with metallicity, is well-explained by the accepted model of dynamical evolution of GCs through mass segregation and the preferential loss of low-mass stars, and these data are among the best available to constrain this process.

Experimental characterization of tissue structure and the impact of forming fabric on tissue properties
Creators: name: Srivastava, Prabhat
Publisher: name: University of British Columbia
Year: 2021

description: Low basis weight tissue papers (≤ 25 gsm) are extensively used in our day-to-day life. They are softer, stretchy and have high water absorbency compared to writing or printing paper. During tissue paper manufacturing, a slurry of pulp and water is carried on a forming fabric which is pressed onto a chemically coated “Yankee” dryer which rotates at high speed (1200-2200 m/min) and is maintained at ≈ 100◦C. After drying on Yankee, the sheet is scraped off Yankee with the help of a stationary creping blade. The process of removing the sheet from the Yankee is called “creping”. Creping imparts a folded structure to the sheet that is responsible for the desired properties of tissue paper like high bulk, high failure strain, high work to rupture, and increased softness and absorbency. A scientific understanding of the process and its influence on the properties can be useful for enhancing the quality and efficiency of the manufacturing process. The current research studies the influence of creping by performing measurements through experiments on tissue paper samples. An experimental technique based on focus stacking is used to image the edge of a tissue paper. Measurements made using this new technique are quantitatively compared to measurements from scanning electron microscope images. The edge images captured are used to calculate a parameter that quantifies the creped structure and correlates well with the stretch. It provides a measure of foreshortening of the sheet that occurs during creping. The forming fabric imparts an embedded structure on the sheet before pressing on the Yankee. These patterns affect the creping process and thus the tissue quality. Surface images of the forming fabric and the tissue paper formed on it in conjunction with measurements from uni-axial tensile tests are used to study the influence of the forming fabric on tissue paper. A method is proposed through which a surface image of the tissue can be used to estimate stretch. Tissue samples over the life of forming fabric are studied to understand the impact of forming fabric wear on tensile properties.

On partial maps derived from flows

Publisher: name: arXiv
Year: 2022
Subjects: subject: Dynamical Systems (math.DS)
subject: FOS: Mathematics

description: The first-return map, or the Poincaré map, is a fundamental concept in the theory of flows. However, it can generally be defined only partially, and additional conditions are required to define it globally. Since this partiality reflects the dynamics, the flow can be described by considering the domain and behavior of such maps. In this study, we define the concept of first-exit maps and first-return maps, which are partial maps derived from flows, to enable such analysis. Moreover, we generalize some notions related to the first-return maps. It is shown that the boundary points of an open set can be classified based on the behavior of these maps, and that this classification is invariant under topological equivalence. Further, we show that some dynamical properties of a flow can be described in terms of the types of boundary points. In particular, if the flow is planar and the open set has a Jordan curve as its boundary, a more detailed analysis is possible, and we present results on the conditions which restrict possible forms of the first-exit maps . Finally, as an application of the results obtained, we consider the relationship between flows and a class of hybrid systems.

Reinforcement learning for legged robot locomotion
Creators: name: Xie, Zhaoming
Publisher: name: University of British Columbia
Year: 2021

description: Deep reinforcement learning (DRL) offers a promising approach for the synthesis of control policies for legged robots locomotion. However, it remains challenging to learn policies that are robust to uncertainty in the real world to put on physical robots or policies that can handle complicated environments. In this thesis, we take several significant steps towards efficiently learning legged locomotion skills with DRL. First, we present a framework to learn feedback policies for a bipedal robotCassie, utilizing rough motion sketches. An iterative design process is then proposed to refine, compress and combine policies for effective sim-to-real transfer. Second, we explore the role of dynamics randomization on a quadrupedal robotLaikago. We demonstrate that with appropriate design choices, dynamics randomization is often not necessary for sim-to-real. We further analyze situations that randomization would become necessary. Third, we propose and analyze multiple curriculum learning approaches to solve the challenging stepping stone tasks for bipedal locomotion. We demonstrate that gradually increasing task difficulties can reliably train policies that solve challenging stepping stone sequences. Finally, we investigate the combination of reinforcement learning and model-based control by training quadrupedal policies using a centroidal model.

description: In this work, we investigate the preheating mechanism after inflation in general scalar-tensor theories of gravity. In the present scenario, we consider two-field scenario and then derive the potential of exponential and hyperbolic tangent forms. We study the evolution of the background system when the back reaction on the background field is neglected. We examine the particle production due to parametric resonances in both models. We find that in Minkowski space the stage of parametric resonances can be described by the Mathieu equation. Finally, we demonstrate that parametric resonances in our models are sufficiently broad possible for the exponential growth of the number of particles.

Maximum of N Independent Brownian Walkers till the First Exit From the Half Space

description: We consider the one-dimensional target search process that involves an immobile target located at the origin and $N$ searchers performing independent Brownian motions starting at the initial positions $\vec x = (x_1,x_2,..., x_N)$ all on the positive half space. The process stops when the target is first found by one of the searchers. We compute the probability distribution of the maximum distance $m$ visited by the searchers till the stopping time and show that it has a power law tail: $P_N(m|\vec x)\sim B_N (x_1x_2... x_N)/m^{N+1}$ for large $m$. Thus all moments of $m$ up to the order $(N-1)$ are finite, while the higher moments diverge. The prefactor $B_N$ increases with $N$ faster than exponentially. Our solution gives the exit probability of a set of $N$ particles from a box $[0,L]$ through the left boundary. Incidentally, it also provides an exact solution of the Laplace's equation in an $N$-dimensional hypercube with some prescribed boundary conditions. The analytical results are in excellent agreement with Monte Carlo simulations.

description: The microscopic formulae of the bulk viscosity $ζ$ and the corresponding relaxation time $τ_Π$ in causal dissipative relativistic fluid dynamics are derived by using the projection operator method. In applying these formulae to the pionic fluid, we find that the renormalizable energy-momentum tensor should be employed to obtain consistent results. In the leading order approximation in the chiral perturbation theory, the relaxation time is enhanced near the QCD phase transition and $τ_Π$ and $ζ$ are related as $τ_Π=ζ/[β\{(1/3-c_{s}^{2})(ε+P)-2(ε-3P)/9\}]$, where $ε$, $P$ and $c_{s}$ are the energy density, pressure and velocity of sound, respectively. The predicted $ζ$ and $% τ_Π$ should satisfy the so-called causality condition. We compare our result with the results of the kinetic calculation by Israel and Stewart and the string theory, and confirm that all the three approaches are consistent with the causality condition.

title: Intra-state equity implications of country ownership of climate change adaptation
Creators: name: Omukuti, Jessica
Publisher: name: University of Reading
Year: 2020

description: Country ownership of climate change adaptation is a key criteria that defines engagement of LDCs in the international climate finance landscape. Country owned actions reflect LDCs adaptation priorities and needs. Climate justice is achieved when countries that are particularly vulnerable to climate change risks are prioritised in resource allocation to support climate change adaptation. The thesis applies a climate justice and equity lens to existing literature on country ownership and finds limited clarity on knowledge relating to country ownership of what and for whom, with existing assessments biased towards the national and international levels. This thesis investigates whether country ownership principles enable equitable intra-state adaptation i.e. adaptation that addresses local level adaptation needs and reduces the vulnerabilities of local level communities most impacted by climate change. Power is considered inherent to adaptation processes within states. The thesis constructs a conceptual framework of power and influence and applies it to a case study of a Least Developed Countries Fundfunded coastal adaptation project in Tanzania. Qualitative and quantitative data through project document and policy reviews, key informant interviews, questionnaires and Focus Group Discussion in three case study locations. Findings indicate that country ownership does not guarantee that local level vulnerabilities will be addressed. The thesis finds: a) the presence of government control of adaptation finance as preventing stakeholder ownership; b) the failure of country owned adaptation actions to reflect the priorities of local level communities who are most vulnerable to climate change and; c) limited ability of actions that work through local level stakeholders to meaningfully engage local populations that are affected by climate risks. The findings suggest that existing approaches to (international) climate change governance may be replicating injustices across scales and increasing local level vulnerability.
