description: We address a physics-informed neural network based on the concept of random projections for the numerical solution of IVPs of nonlinear ODEs in linear-implicit form and index-1 DAEs, which may also arise from the spatial discretization of PDEs. The scheme has a single hidden layer with appropriately randomly parametrized Gaussian kernels and a linear output layer, while the internal weights are fixed to ones. The unknown weights between the hidden and output layer are computed by Newton's iterations, using the Moore-Penrose pseudoinverse for low to medium, and sparse QR decomposition with regularization for medium to large scale systems. To deal with stiffness and sharp gradients, we propose a variable step size scheme for adjusting the interval of integration and address a continuation method for providing good initial guesses for the Newton iterations. Based on previous works on random projections, we prove the approximation capability of the scheme for ODEs in the canonical form and index-1 DAEs in the semiexplicit form. The optimal bounds of the uniform distribution are parsimoniously chosen based on the bias-variance trade-off. The performance of the scheme is assessed through seven benchmark problems: four index-1 DAEs, the Robertson model, a model of five DAEs describing the motion of a bead, a model of six DAEs describing a power discharge control problem, the chemical Akzo Nobel problem and three stiff problems, the Belousov-Zhabotinsky, the Allen-Cahn PDE and the Kuramoto-Sivashinsky PDE. The efficiency of the scheme is compared with three solvers ode23t, ode23s, ode15s of the MATLAB ODE suite. Our results show that the proposed scheme outperforms the stiff solvers in several cases, especially in regimes where high stiffness or sharp gradients arise in terms of numerical accuracy, while the computational costs are for any practical purposes comparable.

description: The ATP-binding cassette family of transporter proteins, subfamily B (MDR/TAP), member 1 (ABCB1) (P-glycoprotein) transporter is a key component of the blood–brain barrier. Many antidepressants are subject to ABCB1 efflux. Functional polymorphisms of ABCB1 may influence central nervous system bioavailability of antidepressants subject to efflux. Single-nucleotide polymorphisms (SNPs) at rs1045642 (C3435T) of ABCB1 have been associated with efflux pump efficiency. This may explain part of the interindividual variation in antidepressant dose needed to remit. Individuals (N=113) with DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) major depressive disorder (MDD) were treated with escitalopram (ESC) or venlafaxine (VEN) over 8 weeks. The17-item Hamilton Depression Rating Scale was assessed serially, blind to genotype. SNP rs1045642 of ABCB1 along with two SNPs previously reported to be in linkage disequilibrium with it (rs2032582 and rs1128503) were genotyped. Demographic features, clinical features, P450 metabolizer status and 5-HTTLPR (serotonin-transporter-linked promoter region) genotype were controlled for. Carriers of rs1045642 TT needed on average 11 mg of ESC to remit, whereas TC and CC carriers required 24 and 19 mg, respectively (P 0.0001). This equates to a 2.0- (95% confidence interval=1.5–3.4; P<0.001) fold greater ESC dose needed to remit for C carriers compared with TT carriers at rs1045642. Of VEN-treated subjects carrying TT genotype at rs1045642, 73.3% remitted compared with 12.5% for CC genotype (odds ratio=6.69; 95% confidence interval=1.72–25.9, P=0.006). These data suggest that antidepressant dose needed to remit can be predicted by an ABCB1 SNP. This has the potential clinical translation implications for dose selection and remission from MDD.

description: Increasing temperatures during summer put the health of unhoused people at risk in Berlin. This article examines an NGO heat relief project as a specific problematization of the phenomenon of urban heat. The paper combines qualitative interviews with unhoused activists, potential clients, and project staff with participant observation as a volunteer at the heat relief project. It finds that the heat relief project employs an experimental approach that attempts to enroll a variety of actors to join its problematization. However, this problematization is contested by activists and unhoused people, as they have their own strategies for dealing with urban heat. Another finding is that due to its seasonal nature and unpredictability, urban heat holds the potential to engage and disengage actors and shape political action. This paper contributes to research on climate change's effects on so-called 'vulnerable' communities and the different ways urban heat holds political potential.

description: For terahertz spectroscopy on single crystals, the wavelength $λ$ often is comparable to the size of the studied samples, emphasizing diffraction effects. Using a continuous-wave terahertz spectrometer in transmission geometry, we address the effect of the sample size on the achievable accuracy of the optical properties, focusing in particular on the phase data. We employ $α$-lactose monohydrate as a paradigmatic example and compare data that were measured using apertures with diameters D in the range from 10 mm to 0.2 mm. For small D, strong diffraction typically invalidates a quantitative analysis of the transmitted amplitude at low frequencies. The phase data, however, can be evaluated to lower frequency and show a more systematic dependence on D. For a quantitative analysis, we employ a waveguide picture for the description of small apertures with a cylindrical bore. For D as small as 0.2 mm, corresponding to 1/D = 50 cm$^{-1}$, a circular waveguide does not support propagating waves below its cut-off frequency $1/λ_c = ω_c/2πc \approx 29$ cm$^{-1}$. Experimentally, we confirm this cut-off for cylindrical apertures with a thickness $d_{ap} = 1$ mm. Close to $ω_c$, the measured phase velocity is an order of magnitude larger than $c$, the speed of light in vacuum. The cut-off is washed out if a sample is mounted on a thin aperture with a conical bore. In this case, the phase data of $α$-lactose monohydrate for D = 0.2 mm can quantitatively be described down to about 10 cm$^{-1}$ if the waveguide-like properties of the aperture are taken into account in the analysis.

description: There have recently been significant advances in the accuracy of algorithms proposed for time series classification (TSC). However, a commonly asked question by real world practitioners and data scientists less familiar with the research topic, is whether the complexity of the algorithms considered state of the art is really necessary. Many times the first approach suggested is a simple pipeline of summary statistics or other time series feature extraction approaches such as TSFresh, which in itself is a sensible question; in publications on TSC algorithms generalised for multiple problem types, we rarely see these approaches considered or compared against. We experiment with basic feature extractors using vector based classifiers shown to be effective with continuous attributes in current state-of-the-art time series classifiers. We test these approaches on the UCR time series dataset archive, looking to see if TSC literature has overlooked the effectiveness of these approaches. We find that a pipeline of TSFresh followed by a rotation forest classifier, which we name FreshPRINCE, performs best. It is not state of the art, but it is significantly more accurate than nearest neighbour with dynamic time warping, and represents a reasonable benchmark for future comparison.

description: How does scientific knowledge grow? This question has occupied a central place in the philosophy of science, stimulating heated debates, but yielding no clear consensus. Many explanations can be understood in terms of whether and how they view the expansion of knowledge as proceeding through the accretion of scientific concepts into larger conceptual structures. Here, we examine these views empirically, performing a large-scale analysis of the physical and social sciences, spanning five decades. Using natural language processing techniques, we create semantic networks of concepts, wherein noun phrases become linked when used in the same paper abstract. For both the physical and social sciences, we observe increasingly rigid conceptual cores (i.e., densely connected sets of highly central nodes) accompanied by the proliferation of periphery concepts (i.e., sparsely connected nodes that are highly connected to the core). Subsequently, we examine the relationship between conceptual structure and the growth of scientific knowledge, finding that scientific works are more innovative in fields with cores that have higher conceptual churn and with larger cores. Furthermore, scientific consensus is associated with reduced conceptual churn and fewer conceptual cores. Overall, our findings suggest that while the organization of scientific concepts is important for the growth of knowledge, the mechanisms vary across time.

description: We investigated the instability of two-dimensional wave fields and its recurrent evolution in time by means of the Alber equation for narrow-banded random surface waves in deep water, subject to inhomogeneous disturbances. The study is started from symmetric spectra and then continued for realistic asymmetric JONSWAP spectrum of ocean waves. Criteria for the instability, both in one-dimensional and two-dimensional cases, are suggested. For the unstable conditions, long-time evolution is simulated and the recurrent evolution is obtained which enables us to study the probability of freak waves. The results are compared to the values given by the Rayleigh distribution and to the Forristall distribution. In particular, it is found that the transition to instability, the most unstable mode, the recurrence duration and the freak wave probability all depend solely on one parameter which is ?

description: Background: This study sheds important light on the association between sino-nasal symptoms and global quality of life in patients with chronic rhinosinusitis waiting for endoscopic sinus surgery. Using patient-reported information collected pre-operatively, the primary objective was to report on patients’ pre-surgical sino-nasal symptoms and their association with self-reported pain and depression. The secondary objective was to report on levels of depression and pain among patients in the sample reporting severe sleep problems. Methods: This is a cross-sectional study of patient-reported outcomes collected prospectively from a cohort of 261 patients assigned to the wait list for elective endoscopic sinus surgery in a large urban region of Canada. Results: Younger patients and patients with other medical comorbidities were most likely to report significant symptoms of chronic rhinosinusitis and substantial associated pain and depression. In the primary analyses, patients reporting significant symptoms of chronic rhinosinusitis were more likely to report moderate depression or high pain (p < 0.01). Subsequently, chronic rhinosinusitis patients with severe sleep problems were 82% likely to report moderate or severe depression and pain. Conclusion: Preoperative management of depression and pain may be considered in order to improve the health-related quality of life of patients waiting for ESS.

description: This volume features a diversity of proposals gathered around the current efforts in ubiquitous music (or ubimus) research. Three papers provide contributions to timbre interaction involving lay participants. Two proposals target the development of network-based music making, one case features synchronous exchanges of visual code and another case proposes the implementation of musical robots within the context of the Internet of Musical Things. The volume wraps up with an interview on ecocomposition, one of the lines of research that has been nourished by ubimus initiatives.

description: In this paper, we outline and document a new supporting metaphor for creativity, creative semantic anchoring (or CSA method). Creative semantic anchoring involves the verbal contextualization of sound materials in order o enable aesthetic decisions or to facilitate the transmission of musical knowledge. It is useful for dealing with sound classes linked to the daily experience of participants in creative activity - ranging from ambient sound events (e.g., biophonic or mechanical sounds) to instrumental emulations of everyday sounds. The present study focuses on the evaluation of instrumental emulations of everyday sounds using semantic descriptors. We selected a group of descriptors, focussing on the subjective and technical aspects of sound materials, and applied a standardised procedure in order to evaluate the sound samples. In this way, we aimed to identify minimum elements for the semantic descriptions, seeking to obtain a quantitative picture of the relevance of the descriptors from the responses of a group of 58 adults, university students with musical knowledge. The results highlight two creative factors: the originality of the product and the subjects’ familiarity with the sound material. The descriptor agradável [pleasant], linked to strongly subjective aspects, and the descriptor bem feito [well done], which refers to the technical aspects of the sound material, were also highlighted in the measurements made. We discuss the limitations of the study and put the results obtained in the context of the semantic proposals of support for creative activities.

An exploration of factors influencing organisational learning transfer using an activity system analytical framework
Creators: name: Lever, Paul Edwin
Publisher: name: Swinburne
Year: 2024

description: Personal and professional development and maximising organisational returns from training investment continues to be a significant issue for managers globally. The objectives of this study were to explore overarching learning transfer barriers as moderating factors influencing learning transfer and identify a simplified methodology and process for investigating learning transfer issues within organisations. Research findings highlighted ninety percent of employees interviewed experienced low learning support and accountability for their learning transfer both from their organisation and their manager. Further results reported a lack of organisational processes for learning which gave rise to poor learning transfer rates and that this study's adapted activity system analytical framework was an appropriate method for exploring factors that influenced learning transfer within organisations.

description: Privacy-preserving machine learning (PPML) solutions are gaining widespread popularity. Among these, many rely on homomorphic encryption (HE) that offers confidentiality of the model and the data, but at the cost of large latency and memory requirements. Pruning neural network (NN) parameters improves latency and memory in plaintext ML but has little impact if directly applied to HE-based PPML.
 We introduce a framework called HE-PEx that comprises new pruning methods, on top of a packing technique called tile tensors, for reducing the latency and memory of PPML inference. HE-PEx uses permutations to prune additional ciphertexts, and expansion to recover inference loss. We demonstrate the effectiveness of our methods for pruning fully-connected and convolutional layers in NNs on PPML tasks, namely, image compression, denoising, and classification, with autoencoders, multilayer perceptrons (MLPs) and convolutional neural networks (CNNs).
 We implement and deploy our networks atop a framework called HElayers, which shows a 10-35% improvement in inference speed and a 17-35% decrease in memory requirement over the unpruned network, corresponding to 33-65% fewer ciphertexts, within a 2.5% degradation in inference accuracy over the unpruned network. Compared to the state-of-the-art pruning technique for PPML, our techniques generate networks with 70% fewer ciphertexts, on average, for the same degradation limit.

description: We present an Equation/Variable free machine learning (EVFML) framework for the control of the collective dynamics of complex/multiscale systems modelled via microscopic/agent-based simulators. The approach obviates the need for construction of surrogate, reduced-order models.~The proposed implementation consists of three steps: (A) from high-dimensional agent-based simulations, machine learning (in particular, non-linear manifold learning (Diffusion Maps (DMs)) helps identify a set of coarse-grained variables that parametrize the low-dimensional manifold on which the emergent/collective dynamics evolve. The out-of-sample extension and pre-image problems, i.e. the construction of non-linear mappings from the high-dimensional input space to the low-dimensional manifold and back, are solved by coupling DMs with the Nystrom extension and Geometric Harmonics, respectively; (B) having identified the manifold and its coordinates, we exploit the Equation-free approach to perform numerical bifurcation analysis of the emergent dynamics; then (C) based on the previous steps, we design data-driven embedded wash-out controllers that drive the agent-based simulators to their intrinsic, imprecisely known, emergent open-loop unstable steady-states, thus demonstrating that the scheme is robust against numerical approximation errors and modelling uncertainty.~The efficiency of the framework is illustrated by controlling emergent unstable (i) traveling waves of a deterministic agent-based model of traffic dynamics, and (ii) equilibria of a stochastic financial market agent model with mimesis.

description: Abstract: Timbre is among the topics of ubiquitous music research featuring some of the most difficult conceptual and methodological challenges, especially when targeting lay-oriented interaction. Timbre parametrization cannot be handled by simplistic or arbitrary mapping strategies. Also, semantic abstractions may not be amenable to untrained stakeholders. To deal with casual usage of complex parametric configurations, we developed a two-tier approach to an ecology of metaphors for creative action. An exploratory study of usage of the Sound Sphere Metaphor - by undergraduate music students with no previous training on audio tools - yielded successful creative outcomes but also pointed to room for improvement in the experimental procedures. Resumo: Discutimos abordagens recentes de suporte assíncrono para atividades musicais online para vários perfis de participantes, incluindo os iniciantes. O timbre é um tópico emergente da pesquisa em música ubíqua que apresenta desafios conceituais e metodológicos para a interação musical orientada a leigos. Por um lado, o timbre envolve processos perceptuais complexos que não estão contemplados nas estratégias de mapeamentos diretos ou arbitrários de parâmetros sonoros. Por outro lado, o uso de termos abstratos também pode impossibilitar o acesso aos interessados que não dominam o arcabouço conceitual musical. Desenvolvemos uma abordagem em dois níveis desde um enfoque ecológico para a ação criativa para viabilizar o suporte para interação timbrística por parte de usuários causais. Realizamos um estudo exploratório dentro do contexto das atividades curriculares de um curso introdutório em tecnologia musical. Discutimos os resultados e as implicações do uso da ecologia de metáforas vinculadas ao conceito da Esfera Sonora para o desenvolvimento do suporte à criatividade musical cotidiana.

description: Multiwinner voting rules can be used to select a fixed-size committee from a larger set of candidates. We consider approval-based committee rules, which allow voters to approve or disapprove candidates. In this setting, several voting rules such as Proportional Approval Voting (PAV) and Phragmén's rules have been shown to produce committees that are proportional, in the sense that they proportionally represent voters' preferences; all of these rules are strategically manipulable by voters. On the other hand, a generalisation of Approval Voting gives a non-proportional but strategyproof voting rule. We show that there is a fundamental tradeoff between these two properties: we prove that no multiwinner voting rule can simultaneously satisfy a weak form of proportionality (a weakening of justified representation) and a weak form of strategyproofness. Our impossibility is obtained using a formulation of the problem in propositional logic and applying SAT solvers; a human-readable version of the computer-generated proof is obtained by extracting a minimal unsatisfiable set (MUS). We also discuss several related axiomatic questions in the domain of committee elections.
