description: Machine learning models commonly exhibit unexpected failures post-deployment due to either data shifts or uncommon situations in the training environment. Domain experts typically go through the tedious process of inspecting the failure cases manually, identifying failure modes and then attempting to fix the model. In this work, we aim to standardise and bring principles to this process through answering two critical questions: (i) how do we know that we have identified meaningful and distinct failure types?; (ii) how can we validate that a model has, indeed, been repaired? We suggest that the quality of the identified failure types can be validated through measuring the intra- and inter-type generalisation after fine-tuning and introduce metrics to compare different subtyping methods. Furthermore, we argue that a model can be considered repaired if it achieves high accuracy on the failure types while retaining performance on the previously correct data. We combine these two ideas into a principled framework for evaluating the quality of both the identified failure subtypes and model repairment. We evaluate its utility on a classification and an object detection tasks. Our code is available at https://github.com/Rokken-lab6/Failure-Analysis-and-Model-Repairment

description: Routing information through networks is a universal phenomenon in both natural and manmade complex systems. When each node has full knowledge of the global network connectivity, finding short communication paths is merely a matter of distributed computation. However, in many real networks nodes communicate efficiently even without such global intelligence. Here we show that the peculiar structural characteristics of many complex networks support efficient communication without global knowledge. We also describe a general mechanism that explains this connection between network structure and function. This mechanism relies on the presence of a metric space hidden behind an observable network. Our findings suggest that real networks in nature have underlying metric spaces that remain undiscovered. Their discovery would have practical applications ranging from routing in the Internet and searching social networks, to studying information flows in neural, gene regulatory networks, or signaling pathways.

description: The mechanical performance of reinforced composites is strongly influenced at different scales by the stress transferred at the matrix-fibre interfaces and at any surface where material discontinuity occurs. In particular, the mechanical response of elastomeric composites where the reinforcement is composed by cords with helically wound fibres is heavily compromised by fatigue and delamination phenomena occurring at cord-rubber as well as at the ply interfaces, since rubber and polymeric matrices are mainly vulnerable to the accumulation of deviatoric energy due to the shear stresses transferred across the surfaces. Despite the large diffusion of composites in a vast field of applications and the mature knowledge of their behaviour, some key mechanical aspects underlying failure mechanisms are still partially unclear. For example, stress amplification and strain localization are often difficult to predict by means of analytical solutions and averaging techniques that usually conceal stress gradients. In this work, we analyse coupling between torsional and tensile loads in twisted cords, which are adopted in many cases to reinforce composites and rubbers in tire applications. We provide a model characterized by an enriched cord-matrix mechanical interplay able to theoretically explain and predict actual stress distributions responsible for the onset of delamination and fatigue-guided phenomena that are experimentally observed in these composites. In particular, we demonstrate that the assumption of a monoclinic/trigonal behaviour for the mechanical response of the hierarchical strands allows to estimate, by means of analytical formulas and a homogenization approach, hitherto neglected shear stresses at the matrix-reinforcement interface. These stresses are transferred to the neighbouring regions, leading to post-elastic behaviour and failure events.

Connectivity and Dynamics of Neuronal Networks as Defined by the Shape of Individual Neurons

Year: 2008
Subjects: subject: Neurons and Cognition (q-bio.NC)
subject: FOS: Biological sciences

description: Neuronal networks constitute a special class of dynamical systems, as they are formed by individual geometrical components, namely the neurons. In the existing literature, relatively little attention has been given to the influence of neuron shape on the overall connectivity and dynamics of the emerging networks. The current work addresses this issue by considering simplified neuronal shapes consisting of circular regions (soma/axons) with spokes (dendrites). Networks are grown by placing these patterns randomly in the 2D plane and establishing connections whenever a piece of dendrite falls inside an axon. Several topological and dynamical properties of the resulting graph are measured, including the degree distribution, clustering coefficients, symmetry of connections, size of the largest connected component, as well as three hierarchical measurements of the local topology. By varying the number of processes of the individual basic patterns, we can quantify relationships between the individual neuronal shape and the topological and dynamical features of the networks. Integrate-and-fire dynamics on these networks is also investigated with respect to transient activation from a source node, indicating that long-range connections play an important role in the propagation of avalanches.

description: This is a study about how American art museums can become more resilient in the 21st century. As the external environment changes, art museum leadership must explore and consider new approaches in response. One key, and consistently underdeveloped area lies in the implementation of innovative strategies around the internal operations of museums related to staff and structure. A select group of art museum leaders are beginning to experiment with new practices in this area, especially around the development of strategies that relate to organizational culture, experimentation and innovation, and staff alignment around institutional core values. By focusing on strategies that invest in their staff, these museum leaders are discovering improved institutional relevance, flexibility, responsiveness, and collaboration. In other words, they are increasing institutional resilience. The examples from these leading art museum directors serve as exciting models for other leaders and practitioners in the field, informing strong next practices that prepare art museums for work in the 21st century.

description: Following our recent work on Type II supernovae (SNe), we present a set of 1D nonlocal thermodynamic equilibrium radiative transfer calculations for nebular-phase Type Ibc SNe starting from state-of-the-art explosion models with detailed nucleosynthesis. Our grid of progenitor models is derived from He stars that were subsequently evolved under the influence of wind mass loss. These He stars, which most likely form through binary mass exchange, synthesize less oxygen than their single-star counterparts with the same zero-age main sequence (ZAMS) mass. This reduction is greater in He-star models evolved with an enhanced mass loss rate. We obtain a wide range of spectral properties at 200d. In models from He stars with an initial mass >6Msun, the [OI] 6300, 6364 is of comparable or greater strength than [CaII] 7291,7323 -- the strength of [OI] 6300, 6364 increases with He-star initial mass. In contrast, models from lower mass He stars exhibit a weak [OI] 6300, 6364, strong [CaII] 7291,7323, but also strong NII lines and FeII emission below 5500A. The ejecta density, modulated by the ejecta mass, the explosion energy, and clumping, has a critical impact on the gas ionization, line cooling, and the spectral properties. FeII dominates the emission below 5500A and is stronger at earlier nebular epochs. It ebbs as the SN ages, while the fractional flux in [OI] 6300, 6364 and [CaII] 7291,7323 increases, with a similar rate, as the ejecta recombine. Although the results depend on the adopted wind mass loss rate and pre-SN mass, we find that He stars of 6-8Msun initially (ZAMS mass of 23-28Msun) match adequately the properties of standard SNe Ibc. Our results for less massive He stars are more perplexing, since the predicted spectra are not seen in nature. They may be missed by current surveys or associated with Type Ibn SNe in which interaction dominates over decay power. [Abridged]

description: A theory of both linear and nonlinear electromagnetic response of a single QD exposed to quantum light, accounting the depolarization induced local--field has been developed. Based on the microscopic Hamiltonian accounting for the electron--hole exchange interaction, an effective two--body Hamiltonian has been derived and expressed in terms of the incident electric field, with a separate term describing the QD depolarization. The quantum equations of motion have been formulated and solved with the Hamiltonian for various types of the QD excitation, such as Fock qubit, coherent fields, vacuum state of electromagnetic field and light with arbitrary photonic state distribution. For a QD exposed to coherent light, we predict the appearance of two oscillatory regimes in the Rabi effect separated by the bifurcation. In the first regime, the standard collapse--revivals phenomenon do not reveal itself and the QD population inversion is found to be negative, while in the second one, the collapse--revivals picture is found to be strongly distorted as compared with that predicted by the standard Jaynes-Cummings model. %The model developed can easily be extended to %%electromagnetic excitation. For the case of QD interaction with arbitrary quantum light state in the linear regime, it has been shown that the local field induce a fine structure of the absorbtion spectrum. Instead of a single line with frequency corresponding to which the exciton transition frequency, a duplet is appeared with one component shifted by the amount of the local field coupling parameter. It has been demonstrated the strong light--mater coupling regime arises in the weak-field limit. A physical interpretation of the predicted effects has been proposed.

The program offers buyers of EVs a $5,000 credit, or $2,500 for the purchase of a short range plug-in hybrid vehicle. And these can be stacked on a $5,000 credit in B.C. and an $8,000 credit in Quebec. The new EV rebate programs raises several questions. Chief among them is whether or not the government should be subsidizing electric vehicles at all?

Characterization of optical transduction-based molecular systems and nanoparticles for the development of chemical sensors

description: With the increasing importance that nanotechnologies have in everyday life, it is not difficult to realize that also a single molecule, if properly designed, can be a device able to perform useful functions: such a chemical species is called chemosensor, that is a molecule of abiotic origin that signals the presence of matter or energy. Signal transduction is the mechanism by which an interaction of a sensor with an analyte yields a measurable form of energy.  When dealing with the design of a chemosensor, we need to take into account a “communication requirement” between its three component: the receptor unit, responsible for the selective analyte binding, the spacer, which controls the geometry of the system and modulates the electronic interaction between the receptor and the signalling unit, whose physico-chemical properties change upon complexation. A luminescent chemosensor communicates a variation of the physico-chemical properties of the receptor unit with a luminescence output signal. 
This thesis work consists in the characterization of new molecular and nanoparticle-based system which can be used as sensitive materials for the construction of new optical transduction devices able to provide information about the concentration of analytes in solution. In particular two direction were taken. The first is to continue in the development of new chemosensors, that is the first step for the construction of reliable and efficient devices, and in particular the work will be focused on chemosensors for metal ions for biomedical and environmental applications. The second is to study more efficient and complex organized systems, such as derivatized silica nanoparticles. These system can potentially have higher sensitivity than molecular systems, and present many advantages, like the possibility to be ratiometric, higher Stokes shifts and lower signal-to-noise ratio.
The Effect of Metronome Pacing on Gait in Healthy Subjects

description: The complex process of gait is rendered partially automatic by central pattern generators (CPGs). To further our understanding of their role in gait control in healthy subjects, we applied a paradigm of anti-phase, or syncopated, movement to gait. To provide a context for our results, we reviewed the literature on in-phase, or synchronized, gait. The review results are as follows. Auditory cueing increased step/stride rate for older subjects, but not younger. Stride rate variability decreased for younger subjects, perhaps because the metronome’s cue acted as a temporal ‘anchor point’ for each step. Step width increased in half of the treadmill studies, but none of the overground ones, suggesting a cumulative effect of the attentional demands of synchronizing gait while on a treadmill. Time series analysis revealed that the α exponent was the most sensitive parameter reported, decreasing toward anti-persistence in almost all cued-gait studies. This project compares in-phase (IN) and anti-phase gait (ANTI) in young and old healthy subjects. We expected gait to be less disrupted during ANTI trials at preferred speed, when the facilitating effect of CPGs would be strongest. The measures step time variability, jerk index, and harmonic ratio quantified gait perturbation: none indicated that ANTI was easiest at preferred walking speed. Surprisingly, the gait of older subjects was no more perturbed than that of younger subjects. When they successfully matched the pace of the beat, they unwittingly synchronized to it. The temporal relationship of their steps to the beat was the same in the IN and ANTI conditions. Younger subjects, visibly struggling during ANTI trials, were able to walk in syncopation. This result suggests that cognitive resources available only to the younger group are required to resist synchronizing to the beat.

Evidently the time that a customer (a person, a job, a message) spends in this kind of systems, its sojourn time, is an important measure of its performance, among others. In this work, the practical statistical known results about the sojourn time of a customer, in a Jackson network, distribution are collected and presented. And an emphasis is set on the numerical methods applicable to compute the distribution function and the moments.

title: Logic and Neurosymbolic Approaches for Temporal Phenomena Recognition and Multi-modal Classification
Creators: name: Pitsikalis, Emmanouil
Publisher: name: University of Liverpool Repository
Year: 2024

description: This thesis deals with two main topics. These are, first, the use of temporal logics for temporal phenomena recognition, and second, a neurosymbolic approach for multi-modal classification. Both of these topics are motivated by real existing problems of the maritime domain.

Concerning the first topic, we formally introduce a new temporal logic that was created with the aims of being very expressive without sacrificing processing efficiency and also be intuitive enough so that non-experts can use it. Our temporal logic is capable of representing instantaneous and durative temporal phenomena. We illustrate its expressive power both through examples, but also study it theoretically in comparison with other well known temporal logics. As our goal is the use of this logic for temporal phenomena recognition, we define criteria for proper stream processors, introduce our open-source implementations and evaluate them on the task of maritime activity recognition on real maritime data. Finally, we present and evaluate a methodology for extracting phenomena definitions, expressed in our logic.

Concerning the second topic, that is the neurosymbolic approach for multi-modal classification, we present a methodology for learning rules, fuzzify them and integrate them into a neural network architecture. Our methodology deals with two kinds of inputs, images and related tabular data. We evaluate our approach on the task of ship type classification using real-world maritime data and vessel images.

Finally, we present two maritime applications that employ the two main contributions of this thesis, i.e., our logic-based methodology for phenomena recognition, and our neurosymbolic approach for multi-modal classification. More specifically we employ them for the tasks of near-port maritime surveillance, and joint ship type classification with maritime activity recognition.

description: We investigate the minimal supergravity (mSUGRA) signals at the LHC in the context of supercritical string cosmology (SSC). In this theory, the presence of a time dependent dilaton provides us with a smoothly evolving dark energy and modifies the dark matter allowed region of the mSUGRA model with standard cosmology. Such a dilaton dilutes the supersymmetric dark matter density (of neutralinos) by a factor O(10) and consequently the regions with too much dark matter in the standard scenario are allowed in the SSC. The final states expected at the LHC in this scenario, unlike the standard scenario, consist of Z bosons, Higgs bosons, and/or high energy taus. We show how to characterize these final states and determine the model parameters. Using these parameters, we determine the dark matter content and the neutralino-proton cross section. All these techniques can also be applied to determine model parameters in SSC models with different SUSY breaking scenarios.

description: The aim of this paper is to contribute to the understanding and to model the processes controlling the amplitude of the wind of Rayleigh-Benard convection. We analyze results from direct simulation of an L/H = 4 aspect-ratio domain with periodic sidewalls at Ra = 1e5; 1e6; 1e7; 1e8 and at Pr = 1 by decomposing independent realizations into wind and fluctuations. It is shown that deep inside the thermal boundary layer, horizontal heat-fuxes exceed the average vertical heat-fux by a factor 3 due to the interaction between the wind and the mean temperature field. These large horizontal heat-fluxes are responsible for spatial temperature differences that drive the wind by creating pressure gradients. The wall fluxes and turbulent mixing in the bulk provide damping. Using the DNS results to parameterise the unclosed terms, a simple model capturing the essential processes governing the wind structure is derived. The model consists of two coupled differential equations for wind velocity and temperature amplitude. The equations indicate that the formation of a wind structure is inevitable due to the positive feedback resulting from the interaction between the wind and temperature field. Furthermore, the wind velocity is largely determined by the turbulence in the bulk rather than by the wall-shear stress. The model reproduces the Ra dependence of wind Reynolds number and temperature amplitude.

description: Part of a collection of correspondence from Kathleen Raine to Robin Skelton. Skelton was a British poet, academic, anthologist, and practicing Wiccan. He taught at Manchester University before emigrating to Canada in 1963, where he taught creative writing at the University of Victoria and started the literary magazine The Malahat Review. Also included are some letters to Skelton’s wife Sylvia, and his daughters. Spanning close to forty-five years, the correspondence discusses poetry, writing, and philosophy; particularly Platonism and Neoplatonism. Raine often refers to the writings of William Blake and W. B. Yeats. Many letters also mention contemporary literary figures at the time including: Herbert Read, Peter Russell, Liam Miller, and Thurairajah Tambimuttu. In this letter, Raine hopes to plan an evening with Skelton and asks after a proof of her recent publication on Yeats.
Breathing mode frequencies of a rotating Fermi gas in the BCS-BEC crossover region

description: We study the breathing mode frequencies of a rotating Fermi gas trapped in a harmonic plus radial quartic potential. We find that as the radial anharmonicity increases, the lowest order radial mode frequency increases while the next lowest order radial mode frequency decreases. Then at a critical anharmonicity, these two modes merge and beyond this merge the cloud is unstable against the oscillations. The critical anharmonicity depends on both rotational frequency and the chemical potential. As a result of the large chemical potential in the BCS regime, even with a weak anharmonicity the lowest order mode frequency increases with decreasing the attractive interaction. For large enough anharmonicities in the weak coupling BCS limit, we find that the excitation of the breathing mode frequencies make the atomic cloud unstable.

description: Part of a collection of correspondence from Kathleen Raine to Robin Skelton. Skelton was a British poet, academic, anthologist, and practicing Wiccan. He taught at Manchester University before emigrating to Canada in 1963, where he taught creative writing at the University of Victoria and started the literary magazine The Malahat Review. Also included are some letters to Skelton’s wife Sylvia, and his daughters. Spanning close to forty-five years, the correspondence discusses poetry, writing, and philosophy; particularly Platonism and Neoplatonism. Raine often refers to the writings of William Blake and W. B. Yeats. Many letters also mention contemporary literary figures at the time including: Herbert Read, Peter Russell, Liam Miller, and Thurairajah Tambimuttu. In this letter, Raine writes about her religious beliefs and religion and culture.

Gilbert Damping in Conducting Ferromagnets I: Kohn-Sham Theory and Atomic-Scale Inhomogeneity
Creators: name: Garate, Ion
name: MacDonald, Allan H.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: We derive an approximate expression for the Gilbert damping coefficient α_G of itinerant electron ferromagnets which is based on their description in terms of spin-density-functional-theory (SDFT) and Kohn-Sham quasiparticle orbitals. We argue for an expression in which the coupling of magnetization fluctuations to particle-hole transitions is weighted by the spin-dependent part of the theory's exchange-correlation potential, a quantity which has large spatial variations on an atomic length scale. Our SDFT result for α_G is closely related to the previously proposed spin-torque correlation-function expression.

A note on the uniqueness of global static decompositions
Creators: name: Sánchez, Miguel

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We discuss when static Killing vector fields are standard, that is, leading to a global orthogonal splitting of the spacetime. We prove that such an orthogonal splitting is unique whenever the natural space is compact. This is carried out by proving that many notable spacelike submanifolds must be contained in an orthogonal slice. Possible obstructions to the global splitting are also considered.

description: A new germacrane-type sesquiterpenoid (1) and a new alkamide (2), as well as six known compounds (3–8) were isolated from the capitula of Chrysanthemum morifolium cv. Fubaiju. The new structures were elucidated by comprehensive spectroscopic analysis and quantum chemical calculations. The known structures were characterised via 1D NMR data compared with the already existing literature data. Among the isolates, compound 5 showed inhibitory activity against human lung cancer A549 cells and human hepatoma HepG2 cells with the IC50 values of 19.50 ± 1.23 and 23.24 ± 1.30 µM, respectively, and compound 8 exhibited inhibitory effect on RSV infection with IC50 value of 12.50 ± 1.02 µM.
A pathway towards high throughput Quantum Monte Carlo simulations for alloys: A case study of two-dimensional (2D) $GaS_xSe_{1-x}$

description: The study of alloys using computational methods has been a difficult task due to the usually unknown stoichiometry and local atomic ordering of the different structures experimentally. In order to combat this, first-principles methods have been coupled with statistical methods such as the Cluster Expansion formalism in order to construct the energy hull diagram, which helps to determine if an alloyed structure can exist in nature. Traditionally, density functional theory (DFT) has been used in such workflows. In this work we propose to use chemically accurate many-body variational Monte Carlo (VMC) and diffusion Monte Carlo (DMC) methods to construct the energy hull diagram of an alloy system, due to the fact that such methods have a weaker dependence on the starting wavefunction and density functional, scale similarly to DFT with the number of electrons, and have had demonstrated success for a variety of materials. To carry out these simulations in a high-throughput manner, we propose a method called Jastrow sharing, which involves recycling the optimized Jastrow parameters between alloys with different stoichiometries. We show that this eliminates the need for extra VMC Jastrow optimization calculations and results in a significant computational cost savings (on average 1/4 savings of total computational time). Since it is a novel post-transition metal chalcogenide alloy series that has been synthesized in its few-layer form, we used monolayer $GaS_xSe_{1-x}$ as a case study for our workflow. By extensively testing our Jastrow sharing procedure for monolayer $GaS_xSe_{1-x}$ and quantifying the cost savings, we demonstrate how a pathway towards chemically accurate high-throughput simulations of alloys can be achieved using many-body VMC and DMC methods.
Attentional allocation to task-irrelevant fearful faces is not automatic: experimental evidence for the conditional hypothesis of emotional selection

description: A growing body of research indicates that attentional biases toward emotional stimuli are not automatic, but may depend on the relevance of emotion to the top-down search goals of the observer. To determine whether and how this relevance factor modulates attentional allocation to irrelevant fearful faces, four spatial cueing tasks were designed, in which the goal-relevance of completely task-irrelevant (neutral or fearful) cue faces was systematically manipulated by changing the target defining feature. No attentional capture by cue faces (be they neutral or fearful) was observed when the cue faces were completely goal-irrelevant. When faces – but not facial expressions – were goal-relevant, fearful cue faces captured attention, but so did neutral cue faces to a similar extent. Only when facial expressions were explicitly goal-relevant did we observe a difference between attentional allocation to fearful and neutral cue faces, with larger cueing effects for neutral cue faces in the Neutral task, and for fearful cue faces in the Fearful task. Therefore, rather than automatic, attentional allocation to irrelevant fearful faces proved conditional to the explicit relevance of fearful expressions to top-down search goals.
The energy dependence of the multiplicity moments at the LHC

description: In this work, from the experimental data we evaluate the first C-moments of the multiplicity distributions recently measured in proton-proton collisions at the LHC and compare them with the predictions of two models: the Kharzeev-Levin model and the Bialas-Praszalowicz model. We divide the data into three sets according to their phase space coverage: I: $p_T > 100 $ MeV and $|η|< 0.5$; II: $p_T > 100 $ MeV and $|η|< 2.4$ and II: $p_T > 500 $ MeV and $|η|< 2.4$. The mean multiplicity grows with the energy according to a power law and the power is different for each set. The $C_n$ moments grow continuously with the energy, slowly in set I and faster in the other sets. Except for KL in set II, both models reproduce the main features of the data. The negative binomial parameter $k$ decreases continuously with the energy and there is no sign of change in this behavior.

Magnetic impurities in a superconductor: Effect of domain walls and interference

description: We consider the effect of magnetic impurities, modeled by classical spins, in a conventional superconductor. We study their effect on the quasiparticles, specifically on the spin density and local density of states (LDOS). As previously emphasized, the impurities induce multiple scatterings of the quasiparticle wave functions leading to complex interference phenomena. Also, the impurities induce quantum phase transitions in the many-body system. Previous authors studied the effect of either a small number of impurities (from one to three) or a finite concentration of impurities, typically in a disordered distribution. In this work we assume a regular set of spins distributed inside the superconductor in such a way that the spins are oriented, forming different types of domain walls, assumed stable. This situation may be particularly interesting in the context of spin transfer due to polarized currents traversing the material.

description: The fiber bundle model describes a collection of elastic fibers under load. the fibers fail successively and for each failure, the load distribution among the surviving fibers change. Even though very simple, the model captures the essentials of failure processes in a large number of materials and settings. We present here a review of fiber bundle model with different load redistribution mechanism from the point of view of statistics and statistical physics rather than materials science, with a focus on concepts such as criticality, universality and fluctuations. We discuss the fiber bundle model as a tool for understanding phenomena such as creep, and fatigue, how it is used to describe the behavior of fiber reinforced composites as well as modelling e.g. network failure, traffic jams and earthquake dynamics.
