description: A map $f\colon K\to \mathbb R^d$ of a simplicial complex is an almost embedding if $f(σ)\cap f(τ)=\emptyset$ whenever $σ,τ$ are disjoint simplices of $K$. Theorem. Fix integers $d,k\ge2$ such that $d=\frac{3k}2+1$. (a) Assume that $P\ne NP$. Then there exists a finite $k$-dimensional complex $K$ that does not admit an almost embedding in $\mathbb R^d$ but for which there exists an equivariant map $\tilde K\to S^{d-1}$. (b) The algorithmic problem of recognition almost embeddability of finite $k$-dimensional complexes in $\mathbb R^d$ is NP hard. The proof is based on the technique from the Matoušek-Tancer-Wagner paper (proving an analogous result for embeddings), and on singular versions of the higher-dimensional Borromean rings lemma and a generalized van Kampen--Flores theorem.

subject: Machine learning not elsewhere classified

description: When the underlying distribution of a stream of incoming data changes, existing models trained on previous data may degrade in performance. Known as concept drift, one way to characterise these changes, is by measuring the magnitude at which these distributions change. However, in high dimensions, do so directly is practically impossible. Therefore, this thesis develops a method that can measure these high-dimensional distributional changes, by exploiting existing relationships between the variables in the distribution. This thesis then shows that this method provides a whole new set of possibilities with regards to visualising, analysing, and adapting to concept drift.

description: Thyroid cancer has been the fastest rising malignancy since the 20th century. Although the instance rates are continuously increasing, many clinical challenges around its pathogenesis, diagnosis, and prognosis are still waiting to be resolved. This research then adopts machine learning, specifically data mining and deep learning techniques, to help address the challenges and reveal the mystery around thyroid cancer. With the proposed algorithms and systems, the risk factors correlated with the disease were determined, and the comprehensive diagnosis was achieved in assisting clinicians to gain “second opinions” in the decision-making process, aiming for a promising prognosis for the target patient.

description: Discussion forum is an essential component of online courses. To gain analytical insights from online student discussions on these forums, automatic classifiers were often adopted. However, existing studies mostly stressed the accuracy of a classifier, while the fairness of the classifier remains largely unexplored. Thus, we provided in-depth accuracy and fairness evaluations of popular Machine Learning (ML) models used for educational classification tasks. Further, to empower these models in both accuracy and fairness dimensions, we proposed sampling-based techniques and showed that our approaches can empower ML models in both accuracy and fairness dimensions across different educational predictive tasks.
title: The drummer’s discourse : an exploration of rhythmic syntax for the enhancement of phrasing within improvised drumset performance
Creators: name: McCoullough, A
Publisher: name: University of Tasmania
Year: 2021

description: The capacity to generate and reorganise rhythmic content in the course of improvise performance is noted as a critical aspect for improvising musicians. As such, this research considers a novel way of extending and revitalising drumset practice using my own performances to consider rhythmic invention and arrangement. This investigatory tack is used to reframe my own drumset practice and provide potential applications for drummers and improvising musicians. The outcomes from this performance-led research are represented in a folio of recorded performances and a contextualising exegesis. The construct of syntax is employed by this study to examine its effective appropriateness for rhythmic analysis, cognitive representation, and drumset practice development. This builds on the body of knowledge that considers musical syntax by presenting a framework for interrogating improvisation, whilst developing unique parameters for improvised drumset performance practice to operate. An iterative cycle of active learning has been applied to four recordings captured in live and studio environments by this research. These recordings consist of original works, along with Thelonious Monk compositions. At the conclusion of each recording, performance excerpts were transcribed and situated in a developed evaluative mechanism. This process consolidated rhythmic phrasing through analysis and formed source material for reflection, conceptualisation, and experimentation. Aspects of new learning that emerged from engagement with the above stages were then focused in subsequent recordings. This research has offered an appropriate method for cross-domain linking with regards to theoretical and empirical perspectives within improvisation. The impact of these associations has led to a critical awareness of syntactic cognitive filters for the enhancement of rhythmic phrasing in improvised drumset performance practice.

description: As the world transitions to renewables it is important that people use energy at the ‘right’ time, such as when the sun shines. The sector believes that providing energy feedback will help people do this. However, studies show that energy feedback is not necessarily helpful or accessible for all people.
By talking with households who have solar and batteries, I found that people use lay weather knowledge to guide and understand their energy consumption. On this basis, I propose ways that the energy sector can help the renewable transition by better listening to everyday people and their practical expertise.

description: International development and HCI practitioners recognize the importance of hearing from those who are disadvantaged in decision-making. However, the voices of marginalized communities for whom development interventions are intended remain little heard. This research investigates how to incorporate community voice (CV) into project commissioning. It demonstrates a holistic understanding of top-level decision-making processes and how to meaningfully capture CV, including informed consent, for project development. It critically conceptualizes CV and outlines its benefits through a framework for effective and sustainable project development. More broadly, it extends our understanding of incorporating CV in project, program, and policy decision-making for international development.

description: In zero magnetic field the ground state manifold of a ferromagnetic spin-1 condensate is SO(3) and exhibits $\mathbb{Z}_2$ vortices as topological defects. We investigate the phase ordering dynamics of this system after being quenched into this ferromagnetic phase from a zero temperature unmagnetized phase. Following the quench, we observe the ordering of both magnetic and gauge domains. We find that these domains grow diffusively, i.e. with domain size $L(t)\sim t^{1/2}$, and exhibit dynamic scale invariance. The coarsening dynamics progresses as $\mathbb{Z}_2$ vortices annihilate, however we find that at finite energy a number of these vortices persist in small clumps without influencing magnetic or gauge order. We consider the influence of a small non-zero magnetic field, which reduces the ground state symmetry, and show that this sets a critical length scale such that when the domains reach this size the system dynamically transitions in order parameter and scaling behaviour from an isotropic to an anisotropic ferromagnetic superfluid.

description: The \emph{power graph} $P(G)$ of a group $G$ is the graph whose vertex set is $G$, with $x$ and $y$ joined if one is a power of the other; the \emph{directed power graph} $\vec{P}(G)$ has the same vertex set, with an arc from $x$ to $y$ if $y$ is a power of $x$. It is known that, for finite groups, the power graph determines the directed power graph up to isomorphism. However, it is not true that any isomorphism between power graphs induces an isomorphism between directed power graphs. Moreover, for infinite groups the power graph may fail to determine the directed power graph. In this paper, we consider power graphs of torsion-free groups. Our main results are that, for torsion-free nilpotent groups of class at most $2$, and for groups in which every non-identity element lies in a unique maximal cyclic subgroup, the power graph determines the directed power graph up to isomorphism. For specific groups such as $\mathbb{Z}$ and $\mathbb{Q}$, we obtain more precise results. Any isomorphism $P(\mathbb{Z})\to P(G)$ preserves orientation, so induces an isomorphism between directed power graphs; in the case of $\mathbb{Q}$, the orientations are either all preserved or all reversed. We also obtain results about groups in which every element is contained in a unique maximal cyclic subgroup (this class includes the free and free abelian groups), and about subgroups of the additive group of $\mathbb{Q}$ and about $\mathbb{Q}^n$.

description: High data rates require vast bandwidths, that can be found in the sub-THz band, and high sampling frequencies, which are predicted to lead to a problematically high analog-to-digital converter (ADC) power consumption. It was proposed to use 1-bit ADCs to mitigate this problem. Moreover, oscillator phase noise is predicted to be especially high at sub-THz carrier frequencies. For synchronization the phase must be tracked based on 1-bit quantized observations. We study iterative data-aided phase estimation, i.e., the expectation-maximization and the Fisher-scoring algorithm, compared to least-squares (LS) phase estimation. For phase interpolation at the data symbols, we consider the Kalman filter and the Rauch-Tung-Striebel algorithm. Compared to LS estimation, iterative phase noise tracking leads to a significantly lower estimation error variance at high signal-to-noise ratios. However, its benefit for the spectral efficiency using zero-crossing modulation (ZXM) is limited to marginal gains for high faster-than-Nyquist signaling factors, i.e., higher order ZXM modulation.

description: Acoustic animal monitoring is crucial for biodiversity conservation and management, but conventional methods are extremely labor-intensive. This research presents a Deep Learning-based automatic animal monitoring system for remote wild areas. Due to the lack of power sources and internet connections, the deep models need to run on extremely resource-constrained microcontrollers. This research introduces a generic pipeline for dramatically downsizing the deep models to fit such devices. Furthermore, a new active learning framework is developed to reduce the amount of human input during training time. Beyond standard benchmarks, this research demonstrates the applicability of the proposed methods to real-world conservation biology tasks.

High-pressure hydrothermal growth and characterization of Sr3Os4O14 single crystals

Year: 2023
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Single crystals of the novel strontium osmate Sr3Os4O14 have been grown by the hydrothermal method using opposed anvil high-pressure and high-temperature technique. The reaction took place in sealed gold capsules at 3 GPa and a temperature of 1100 C, with water acting as a solvent. The employed method yields up to 1 mm crystals with quite uncommon double-terminated morphologies. The crystal structure was identified as tetragonal by single-crystal X-ray diffraction, with lattice parameters a = 12.2909(8) A and c = 7.2478(5) A. The structural analysis suggests P42nm or P42/mnm as a possible space group. In general, the structure belongs to the pyrochlore type and is composed of a network of symmetrically arranged OsO6 octahedra. Resistivity measurements evidence a metallic behavior, accompanied by a temperature-independent paramagnetism. Heat capacity measurements reveal a slightly enhanced value of the Sommerfeld coefficient 34 mJ/mol K2. Superconductivity has not been observed down to 2 K.

description: This thesis presents a novel framework for declarative modelling and continual solving of dynamic combinatorial problems (e.g., planning the routes of delivery vehicles).
This framework is then enhanced with a garbage collection mechanism, ensuring that the evolving problem's internal representation remains small as time progresses.
Experiments show that garbage collection vastly improves runtime.
This thesis presents another novel framework allowing experimentation with fairness in similar problems, which we show can achieve remarkably fair and resource-efficient solutions.
Finally, this thesis presents one novel constraint propagation algorithm for variance and one for the Gini coefficient, which we show improve runtime.

description: Qualitative features of multiparticle correlations in light-heavy ion ($p+A$) collisions at RHIC and LHC are reproduced in a simple initial state model of partons in the projectile coherently scattering off localized domains of color charge in the heavy nuclear target. These include i) the ordering of the magnitudes of the azimuthal angle $n$th Fourier harmonics of two-particle correlations $v_n\{2\}$, ii) the energy and transverse momentum dependence of the four-particle Fourier harmonic $v_2\{4\}$, and iii) the energy dependence of four-particle symmetric cumulants measuring correlations between different Fourier harmonics. Similar patterns are seen in an Abelian version of the model, where we observe $v_2\{2\} > v_2\{4\}\approx v_2\{6\}\approx v_2\{8\}$ of two, four, six, and eight particle correlations. While such patterns are often interpreted as signatures of collectivity arising from hydrodynamic flow, our results provide an alternative description of the multiparticle correlations seen in $p+A$ collisions.

description: We present the first shared task for detecting and analyzing code-switching in Guarani and Spanish, GUA-SPA at IberLEF 2023. The challenge consisted of three tasks: identifying the language of a token, NER, and a novel task of classifying the way a Spanish span is used in the code-switched context. We annotated a corpus of 1500 texts extracted from news articles and tweets, around 25 thousand tokens, with the information for the tasks. Three teams took part in the evaluation phase, obtaining in general good results for Task 1, and more mixed results for Tasks 2 and 3.

description: Calculations for open quantum systems are performed usually by taking into account their embedding into one common environment, which is mostly the common continuum of scattering wavefunctions. Realistic quantum systems are coupled however often to more than one continuum. For example, the conductance of an open cavity needs at least two environments, namely the input and the output channel. In the present paper, we study generic features of the transfer of particles through an open quantum system coupled to two channels. We compare the results with those characteristic of a one-channel system. Of special interest is the parameter range which is influenced by singular points. Here, the states of the system are mixed via the environment. In the one-channel case, the resonance structure of the cross section is independent of the existence of singular points. In the two-channel case, however, new effects appear caused by coherence. An example is the enhanced conductance of an open cavity in a certain finite parameter range. It is anti-correlated with the phase rigidity of the eigenfunctions of the non-Hermitian Hamilton operator.

description: High-energy neutrinos originating in astrophysical sources should be accompanied by gamma-rays at production. Depending on the properties of the emission environment and the distance of the source to the Earth, these gamma-rays may be observed directly, or through the detection of lower energy photons that result from interactions with the intervening radiation fields. In this work, we present an automated tool that aims at using data from the Fermi-Large Area Telescope to identify multiwavelength counterparts to astrophysical neutrino events. The main goal of this tool is to enable prompt follow-up observations with ground-based and space-based observatories in order to help pinpoint the neutrino source.

description: This work investigates the effect of nonlinearities on topologically protected edge states in one and two-dimensional phononic lattices. We first show that localized modes arise at the interface between two spring-mass chains that are inverted copies of each other. Explicit expressions derived for the frequencies of the localized modes guide the study of the effect of cubic nonlinearities on the resonant characteristics of the interface which are shown to be described by a Duffing-like equation. Nonlinearities produce amplitude-dependent frequency shifts, which in the case of a softening nonlinearity cause the localized mode to migrate to the bulk spectrum. The case of a hexagonal lattice implementing a phononic analogue of a crystal exhibiting the quantum spin Hall effect is also investigated in the presence of weakly nonlinear cubic springs. An asymptotic analysis provides estimates of the amplitude dependence of the localized modes, while numerical simulations illustrate how the lattice response transitions from bulk-to-edge mode-dominated by varying the excitation amplitude. In contrast with the interface mode of the first example studies, this occurs both for hardening and softening springs. The results of this study provide a theoretical framework for the investigation of nonlinear effects that induce and control topologically protected wave-modes through nonlinear interactions and amplitude tuning.

description: While humans are highly capable of recovering from external disturbances and uncertainties that result in large tracking errors, humanoid robots have yet to reliably mimic this level of robustness. Essential to this is the ability to combine traditional "ankle strategy" balancing with step timing and location adjustment techniques. In doing so, the robot is able to step quickly to the necessary location to continue walking. In this work, we present both a new swing speed up algorithm to adjust the step timing, allowing the robot to set the foot down more quickly to recover from errors in the direction of the current capture point dynamics, and a new algorithm to adjust the desired footstep, expanding the base of support to utilize the center of pressure (CoP)-based ankle strategy for balance. We then utilize the desired centroidal moment pivot (CMP) to calculate the momentum rate of change for our inverse-dynamics based whole-body controller. We present simulation and experimental results using this work, and discuss performance limitations and potential improvements.

description: Smart Buildings (SBs) employ the latest IoT technologies to automate building operations and services. These smart devices can capture and share sensitive and private data about occupants, exposing them to various privacy threats. Nevertheless, the convenience offered by these devices influences users' privacy-related behaviours, and they rarely make active efforts to protect their personal information. To address this tension between data privacy, consent and convenience, this thesis proposes a novel privacy-preserving informed consent management solution. It increases user awareness of data collection and usage, provides fine-grained visibility into privacy conformance and compliance by these devices, and enables informed privacy decision-making.

description: The ubiquity of mobile applications in daily life raises the imperative that apps should reflect end-users' values (e.g., transparency, social recognition). This research conducted a mixed-methods empirical study to understand the values of Bangladeshi female farmers, identify the extent to which the existing agriculture apps reflect their values, and explore possible strategies to address their values in apps. This research identified conformity and security as the most important values for them. Among their 22 preferred values, 15 are reflected in the existing apps and 7 are ignored/violated. This research identified 14 strategies to address Bangladeshi female farmers' values in apps.

description: Structural and topological information play a key role in modeling flow and transport through fractured rock in the subsurface. Discrete fracture network (DFN) computational suites such as dfnWorks are designed to simulate flow and transport in such porous media. Flow and transport calculations reveal that a small backbone of fractures exists, where most flow and transport occurs. Restricting the flowing fracture network to this backbone provides a significant reduction in the network's effective size. However, the particle tracking simulations needed to determine the reduction are computationally intensive. Such methods may be impractical for large systems or for robust uncertainty quantification of fracture networks, where thousands of forward simulations are needed to bound system behavior. In this paper, we develop an alternative network reduction approach to characterizing transport in DFNs, by combining graph theoretical and machine learning methods. We consider a graph representation where nodes signify fractures and edges denote their intersections. Using random forest and support vector machines, we rapidly identify a subnetwork that captures the flow patterns of the full DFN, based primarily on node centrality features in the graph. Our supervised learning techniques train on particle-tracking backbone paths found by dfnWorks, but run in negligible time compared to those simulations. We find that our predictions can reduce the network to approximately 20% of its original size, while still generating breakthrough curves consistent with those of the original network.

A short note on dynamics and degrees of freedom in $2d$ classical gravity

description: We comment on some peculiarities of matter with and without Weyl invariance coupled to classical $2d$ Einstein-Hilbert gravity for several models, in particular, related to the counting of degrees of freedom and on the dynamics. We find that theories where the matter action is Weyl invariant has generically more degrees of freedom than action without the invariance. This follows from the Weyl invariance of the metric equations of motion independently of the invariance of the action. Then, we study another set of models with scalar fields and show that solutions to the equations of motion are either trivial or inconsistent. To our knowledge, these aspects of classical $2d$ gravity have not been put forward and can be interesting to be remembered when using it as a toy model for $4d$ gravity. The goal of this note is also as a pedagogical exercise: our results follow from standard methods, but we emphasize more direct computations.

description: To improve light yield and energy resolution in large-volume neutrino detectors, light concentrators are often mounted on photomultiplier tubes to increase the detection efficiency of optical photons from scintillation or Cherenkov light induced by charged particles. We propose a method to optimize previous light concentrators design in order to attain a field of view of 90 degrees and a geometrical collection efficiency above 98%. This improvement could be crucial to Jinping and other future neutrino experiments whichever it is applicable.

description: Requirements Changes (RCs) such as feature requests are inevitable in software development. RCs are multi-faceted. They have different types, forms, reasons, sources, carriers, and events where they originate. RCs not only pose a risk to the cost, quality, and schedule of the software projects but also result in negative responses from software practitioners involved in the RC handling life cycle, e.g.: anxiety, fatigue or even anger! By elaborating on the multi-faceted nature of RCs, software practitioners’ emotional responses and how they use their emotional intelligence during RC handling, this thesis presents knowledge and practical recommendations to better handle RCs.

description: The distribution of intervals between human actions such as email posts or keyboard strokes demonstrates distinct properties at short vs long time scales. For instance, at long time scales, which are presumably controlled by complex process such as planning and decision making, it has been shown that those inter-event intervals follow a scale-invariant (or power-law) distribution. In contrast, at shorter time-scales - which are governed by different process such as sensorimotor skill - they do not follow the same distribution and little do we know how they relate to the scale-invariant pattern. Here, we analyzed 9 millions intervals between smartphone screen touches of 84 individuals which span several orders of magnitudes (from milliseconds to hours). To capture these intervals, we extend a priority-based generative model to smartphone touching events. At short-time scale, the model is governed by refractory effects, while at longer time scales, the inter-touch intervals are governed by the priority difference between smartphone tasks and other tasks. The flexibility of the model allows to capture inter-individual variations at short and long time scales while its tractability enables efficient model fitting. According to our model, each individual has a specific power-low exponent which is tightly related to the effective refractory time constant suggesting that motor processes which influence the fast actions are related to the higher cognitive processes governing the longer inter-event intervals.

description: We determine the nucleation rates of hard spheres using brute-force molecular dynamics simulations. We overcome nucleation barriers of up to $28 k_B T$, leading to a rigorous test of nucleation rates obtained from rare-event methods and classical nucleation theory. Our brute-force nucleation rates show excellent agreement with umbrella sampling simulations by Filion et al. [J. Chem. Phys. 133, 244115 (2010)] and seeding simulations by Espinosa et al. [J. Chem. Phys. 144, 034501 (2016)].
