description: Quantifying the complex/multifractal organization of the brain signals is crucial to fully understanding the brain processes and structure. In this contribution, we performed the multifractal analysis of the electroencephalographic (EEG) data obtained from a controlled multiple sclerosis (MS) study, focusing on the correlation between the degree of multifractality, disease duration, and disability level. Our results reveal a significant correspondence between the complexity of the time series and multiple sclerosis development, quantified respectively by scaling exponents and the Expanded Disability Status Scale (EDSS). Namely, for some brain regions, a well-developed multifractality and little persistence of the time series were identified in patients with a high level of disability, whereas the control group and patients with low EDSS were characterised by persistence and monofractality of the signals. The analysis of the cross-correlations between EEG signals supported these results, with the most significant differences identified for patients with EDSS $> 1$ and the combined group of patients with EDSS $\leq 1$ and controls. No association between the multifractality and disease duration was observed, indicating that the multifractal organisation of the data is a hallmark of developing the disease. The observed complexity/multifractality of EEG signals is hypothetically a result of neuronal compensation -- i.e., of optimizing neural processes in the presence of structural brain degeneration. The presented study is highly relevant due to the multifractal formalism used to quantify complexity and due to scarce resting-state EEG evidence for cortical reorganization associated with compensation.

description: This paper introduces a novel approach named CrossVideo, which aims to enhance self-supervised cross-modal contrastive learning in the field of point cloud video understanding. Traditional supervised learning methods encounter limitations due to data scarcity and challenges in label acquisition. To address these issues, we propose a self-supervised learning method that leverages the cross-modal relationship between point cloud videos and image videos to acquire meaningful feature representations. Intra-modal and cross-modal contrastive learning techniques are employed to facilitate effective comprehension of point cloud video. We also propose a multi-level contrastive approach for both modalities. Through extensive experiments, we demonstrate that our method significantly surpasses previous state-of-the-art approaches, and we conduct comprehensive ablation studies to validate the effectiveness of our proposed designs.

description: In this paper, the homotopy-perturbation method (HPM) is applied to obtain approximate analytical solutions for the gravitational deflection of light in General Relativity near Schwarzschild black hole surrounded by quintessence (Kiselev black hole). In order to demonstrate that HPM is able to yield acceptable solutions for the null-geodesics with easily computable terms, the HPM is tested for the simple examples of spherically symmetric spacetimes such as Schwarzschild and Reissner-Nordström black holes. After that, the null-geodesics of light passing the vicinity of Kiselev black hole are studied via the HPM in two particular cases regarding the equation of state parameter of quintessence. In addition, a formula for the angle of deflection has been obtained via HPM in the form of a series which allows to calculate the angle with any accuracy without requirement of its smallness.

description: We investigate quasitopological black holes in $(2+1)$ dimensions in the context of electromagnetic-generalized-quasitopological-gravities (EM-GQT). For three different families of geometries of quasitopological nature, we study the causal structure and their response to a probe scalar field. To linear order, we verify that the scalar field evolves stably, decaying in different towers of quasinormal modes. The studied black holes are either charged geometries (regular and singular) or a regular Bañados-Teitelboim-Zanelli (BTZ)-like black hole, both coming from the EM-GQT theory characterized by nonminimal coupling parameters between gravity and a background scalar field. We calculate the quasinormal modes applying different numerical methods with convergent results between them. The oscillations demonstrate a very peculiar structure for charged black holes: in the intermediate and near extremal cases, a particular scaling arises, similar to that of the rotating BTZ geometry, with the modes being proportional to the distance between horizons. For the single horizon black hole solution, we identify the presence of different quasinormal families by analyzing the features of that spectrum. In all three considered geometries, no instabilities were found.

description: The helicity-orbital coupling is an intriguing feature of magnetic skyrmions in frustrated magnets. Here, we explore the skyrmion dynamics in a frustrated magnet based on the $J_{1}$-$J_{2}$-$J_{3}$ classical Heisenberg model explicitly by including the dipole-dipole interaction. The skyrmion energy acquires a helicity dependence due to the dipole-dipole interaction, resulting in the current-induced translational motion with a fixed helicity. The lowest energy states are the degenerate Bloch-type states, which can be used for building the binary memory. By increasing the driving current, the helicity locking-unlocking transition occurs, where the translational motion changes to the rotational motion. Furthermore, we demonstrate that two skyrmions can spontaneously form a bound state. The separation of the bound state forced by a driving current is also studied. In addition, we show the annihilation of a pair of skyrmion and antiskyrmion. Our results reveal the distinctive frustrated skyrmions may enable viable applications in topological magnetism.

description: It is now well-known that automatic speaker verification (ASV) systems can be spoofed using various types of adversaries. The usual approach to counteract ASV systems against such attacks is to develop a separate spoofing countermeasure (CM) module to classify speech input either as a bonafide, or a spoofed utterance. Nevertheless, such a design requires additional computation and utilization efforts at the authentication stage. An alternative strategy involves a single monolithic ASV system designed to handle both zero-effort imposter (non-targets) and spoofing attacks. Such spoof-aware ASV systems have the potential to provide stronger protections and more economic computations. To this end, we propose to generalize the standalone ASV (G-SASV) against spoofing attacks, where we leverage limited training data from CM to enhance a simple backend in the embedding space, without the involvement of a separate CM module during the test (authentication) phase. We propose a novel yet simple backend classifier based on deep neural networks and conduct the study via domain adaptation and multi-task integration of spoof embeddings at the training stage. Experiments are conducted on the ASVspoof 2019 logical access dataset, where we improve the performance of statistical ASV backends on the joint (bonafide and spoofed) and spoofed conditions by a maximum of 36.2% and 49.8% in terms of equal error rates, respectively.

description: The Dirac equation for relativistic electron waves is the parent model for Weyl and Majorana fermions as well as topological insulators. Simulation of Dirac physics in three-dimensional photonic crystals, though fundamentally important for topological phenomena at optical frequencies, encounters the challenge of synthesis of both Kramers double degeneracy and parity inversion. Here we show how type-II Dirac points---exotic Dirac relativistic waves yet to be discovered---are robustly realized through the nonsymmorphic screw symmetry. The emergent type-II Dirac points carry nontrivial topology and are the mother states of type-II Weyl points. The proposed all-dielectric architecture enables robust cavity states at photonic-crystal---air interfaces and anomalous refraction, with very low energy dissipation.
title: Sing a new song : the forging of a new monastic musical voice in post-Vatican II Australia
Creators: name: Lynch, PL
Publisher: name: University of Tasmania
Year: 2019

description: The Second Vatican Council heralded a period of immense and often unprecedented change for all Roman Catholics, nowhere more so than in matters liturgical. Against the backdrop of Sacrosanctum Concilium, promulgated by Paul VI on December 4, 1963, and subsequent Vatican legislation, this dissertation investigates, through an ethnographic methodology, the responses to the challenges and opportunities that arose through the process of liturgical reform within the Australian monastic context. The research focuses on four monastic communities, each of which welcomed the opportunity to participate: the Discalced Carmelite Nuns at the Carmelite Monastery in Kew, Victoria; the Trappist Monks at Tarrawarra Abbey in the Yarra Valley, Victoria; the Benedictine Nuns at Jamberoo Abbey, New South Wales; and the Benedictine Monks at New Norcia, Western Australia. It considers the liturgical music of each of these communities as it evolved over the period from 1960, two years prior to the commencement of the Council, to 2015, marking 50 years since its conclusion. Particular emphasis is placed on the dichotomy of the vernacularisation of their liturgies, and the concomitant necessity to develop sympathetic musical constructs, and the requirement, as mandated by the Council, to preserve the treasury of sacred music, especially Gregorian chant. It demonstrates that through their collective commitment and the expertise of individual musicians from within their ranks as well as further afield they have resolved, to a large extent, the inherent tension between the implementation of liturgical reform and the safeguarding of longstanding traditions in the Roman Church. It provides compelling evidence that, in so doing, they have not only succeeded but indeed excelled in forging a new monastic musical voice in post-Vatican II Australia.

description: We have revisited the mean-field treatment for the Blume-Capel model under the presence of a discrete random magnetic field as introduced by Kaufman and Kanner. The magnetic field ($H$) versus temperature ($T$) phase diagrams for given values of the crystal field $D$ were recovered in accordance to Kaufman and Kanner original work. However, our main goal in the present work was to investigate the distinct structures of the crystal field versus temperature phase diagrams as the random magnetic field is varied because similar models have presented reentrant phenomenon due to randomness. Following previous works we have classified the distinct phase diagrams according to five different topologies. The topological structure of the phase diagrams is maintained for both $H-T$ and $D-T$ cases. Althoug the phase diagrams exhibit a richness of multicritical phenomena we did not found any reentrant effect as have been seen in similar models.

description: The Kelvin-Helmholtz instability is well-known in classical hydrodynamics, where it explains the sudden emergence of interfacial surface waves as a function of the velocity of flow parallel to the interface. It can be carried over to the inviscid two-fluid dynamics of superfluids, to study different types of interfaces and phase boundaries in quantum fluids. We report measurements on the stability of the phase boundary separating the two bulk phases of superfluid 3He in rotating flow, while the boundary is localized with the gradient of the magnetic field to a position perpendicular to the rotation axis. The results demonstrate that the classic stability condition, when modified for the superfluid environment, is obeyed down to 0.4 Tc, if a large fraction of the magnetic polarization of the B-phase is attributed to a parabolic reduction of the interfacial surface tension with increasing magnetic field.

description: Semantic segmentation and stereo matching are two essential components of 3D environmental perception systems for autonomous driving. Nevertheless, conventional approaches often address these two problems independently, employing separate models for each task. This approach poses practical limitations in real-world scenarios, particularly when computational resources are scarce or real-time performance is imperative. Hence, in this article, we introduce S$^3$M-Net, a novel joint learning framework developed to perform semantic segmentation and stereo matching simultaneously. Specifically, S$^3$M-Net shares the features extracted from RGB images between both tasks, resulting in an improved overall scene understanding capability. This feature sharing process is realized using a feature fusion adaption (FFA) module, which effectively transforms the shared features into semantic space and subsequently fuses them with the encoded disparity features. The entire joint learning framework is trained by minimizing a novel semantic consistency-guided (SCG) loss, which places emphasis on the structural consistency in both tasks. Extensive experimental results conducted on the vKITTI2 and KITTI datasets demonstrate the effectiveness of our proposed joint learning framework and its superior performance compared to other state-of-the-art single-task networks.

title: Philosophy without letters : Giorgio Agamben and Indigenous sovereignty
Creators: name: Molad, J
Publisher: name: University of Tasmania
Year: 2019

description: This thesis critically discusses the history of Ontology understood as the implication of ‘being’ within a semiotic and phonetic conception of language. Ontology owes its coherence as a cultural apparatus to the Ancient Greek transformation of the alphabet into a total system of vocalic notation – an unprecedented and revolutionary cultural project that rendered ‘language’ recognisable as an autonomous and hence fully analysable entity. Alphabetisation, in its ancient Greek form, was an originary apparatus of domination aimed at the colonisation of everyday speech for the sake of administration. My analysis shows that the dominance of the semiotic conception of language allows for the development of the science of Grammar and the foreclosure of any linguistic dimension resistant to total alphabetic phonetisation. Philosophy is the discourse that emerges alongside, meditates on the meaning and consequences of, and calls into question this epochal transformation of human speech. Giorgio Agamben’s archaeology of Ontology shows that Aristotle’s Ontology also gave rise to the modern ‘scientific’ concept of ‘Life’ as a sacred political and cultural referent. The sanctity of ‘Life’ emerges alongside the birth of Ontology as a consequence of the way Aristotle naturalises the alphabet as the ultimate code of human speech. As a result, ‘Life’ as a unitary referent owes it coherence to a logical-political operation rather than a natural or religious one. Therefore, only an examination of the way in which Ontology is developed and functions can allow for a consideration of a different conception of language and life. Despite pointing to the limit of a certain dominant conception of politics and language, Agamben’s philosophical practice remains within the orbit of Greek Ontology and Western nihilism. This fails to orient us in light of the immense challenges posed to settler societies faced with the claims of indigenous sovereignty. Agamben’s philosophy assist us in redrawing the boundaries of settler culture in order to better learn how to exit from it – therein lies the importance of studying his work in order to better understand the apparatuses governing our societies and conceptions of humanity. Ultimately, this will only show us the door without opening it for us. It is therefore necessary to move completely beyond the domain of Ontology as handed down by the philosophical tradition in order to make ourselves available for the only political practice that constitutes a task for our era: the development of conditions ripe for the reassertion of Indigenous Sovereignty.

description: We revisit Parker's conjecture of current singularity formation in 3D line-tied plasmas using a recently developed numerical method, variational integration for ideal magnetohydrodynamics in Lagrangian labeling. With the frozen-in equation built-in, the method is free of artificial reconnection, and hence it is arguably an optimal tool for studying current singularity formation. Using this method, the formation of current singularity has previously been confirmed in the Hahm--Kulsrud--Taylor problem in 2D. In this paper, we extend this problem to 3D line-tied geometry. The linear solution, which is singular in 2D, is found to be smooth for arbitrary system length. However, with finite amplitude, the linear solution can become pathological when the system is sufficiently long. The nonlinear solutions turn out to be smooth for short systems. Nonetheless, the scaling of peak current density versus system length suggests that the nonlinear solution may become singular at finite length. With the results in hand, we can neither confirm nor rule out this possibility conclusively, since we cannot obtain solutions with system length near the extrapolated critical value.

description: The automatic classification of X-ray detections is a necessary step in extracting astrophysical information from compiled catalogs of astrophysical sources. Classification is useful for the study of individual objects, statistics for population studies, as well as for anomaly detection, i.e., the identification of new unexplored phenomena, including transients and spectrally extreme sources. Despite the importance of this task, classification remains challenging in X-ray astronomy due to the lack of optical counterparts and representative training sets. We develop an alternative methodology that employs an unsupervised machine learning approach to provide probabilistic classes to Chandra Source Catalog sources with a limited number of labeled sources, and without ancillary information from optical and infrared catalogs. We provide a catalog of probabilistic classes for 8,756 sources, comprising a total of 14,507 detections, and demonstrate the success of the method at identifying emission from young stellar objects, as well as distinguishing between small-scale and large-scale compact accretors with a significant level of confidence. We investigate the consistency between the distribution of features among classified objects and well-established astrophysical hypotheses such as the unified AGN model. This provides interpretability to the probabilistic classifier. Code and tables are available publicly through GitHub. We provide a web playground for readers to explore our final classification at https://umlcaxs-playground.streamlit.app.

Measurement of the $W$ boson polarisation in $t\bar{t}$ events from $pp$ collisions at $\sqrt{s}$ = 8 TeV in the lepton+jets channel with ATLAS

description: This paper presents a measurement of the polarisation of $W$ bosons from $t\bar{t}$ decays, reconstructed in events with one high-$p_{\mbox{T}}$ lepton and at least four jets. Data from $pp$ collisions at the LHC were collected at $\sqrt{s}$ = 8 TeV and correspond to an integrated luminosity of 20.2 fb$^{-1}$. The angle $θ^{*}$ between the $b$-quark from the top quark decay and a direct $W$ boson decay product in the $W$ boson rest frame is sensitive to the $W$ boson polarisation. Two different $W$ decay products are used as polarisation analysers: the charged lepton and the down-type quark for the leptonically and hadronically decaying $W$ boson, respectively. The most precise measurement of the $W$ boson polarisation via the distribution of $\cos{θ^{*}}$ is obtained using the leptonic analyser and events in which at least two of the jets are tagged as $b$-quark jets. The fitted fractions of longitudinal, left- and right-handed polarisation states are $F_{\mathrm{0}}= 0.709 \pm {0.019}$, $F_{\mathrm{L}}= 0.299 \pm {0.015}$ and $F_{\mathrm{R}}= -0.008 \pm {0.014}$, and are the most precisely measured $W$ boson polarisation fractions to date. Limits on anomalous couplings of the $Wtb$ vertex are set.

description: By comparing femtosecond laser pulse induced ferro- and antiferromagnetic dynamics in one and the same material - metallic dysprosium - we show both to behave fundamentally different. Antiferromagnetic order is considerably faster and much more efficiently manipulated by optical excitation than its ferromagnetic counterpart. We assign the fast and extremely efficient process in the antiferromagnet to an interatomic transfer of angular momentum within the spin system. Our findings do not only reveal this angular momentum transfer channel effective in antiferromagnets and other magnetic structures with non-parallel spin alignment, they also point out a possible route towards energy-efficient spin manipulation for magnetic devices.

description: Interior color design is a creative process that endeavors to allocate colors to furniture and other elements within an interior space. While much research focuses on generating realistic interior designs, these automated approaches often misalign with user intention and disregard design rationales. Informed by a need-finding preliminary study, we develop C2Ideas, an innovative system for designers to creatively ideate color schemes enabled by an intent-aligned and domain-oriented large language model. C2Ideas integrates a three-stage process: Idea Prompting stage distills user intentions into color linguistic prompts; Word-Color Association stage transforms the prompts into semantically and stylistically coherent color schemes; and Interior Coloring stage assigns colors to interior elements complying with design principles. We also develop an interactive interface that enables flexible user refinement and interpretable reasoning. C2Ideas has undergone a series of indoor cases and user studies, demonstrating its effectiveness and high recognition of interactive functionality by designers.

description: Scattering of obliquely incident electromagnetic waves from periodically space-time modulated slabs is investigated. It is shown that such structures operate as nonreciprocal harmonic generators and spatial-frequency filters. For oblique incidences, low-frequency harmonics are filtered out in the form of surface waves, while high-frequency harmonics are transmitted as space waves. In the quasisonic regime, where the velocity of the space-time modulation is close to the velocity of the electromagnetic waves in the background medium, the incident wave is strongly coupled to space-time harmonics in the forward direction, while in the backward direction it exhibits low coupling to other harmonics. This nonreciprocity is leveraged for the realization of an electromagnetic isolator in the quasisonic regime and is experimentally demonstrated at microwave frequencies.
Higgs-Zeno Spacetime: Quantum Measurement, Dual Hamiltonians, and Mass-Energy Evolution
Creators: name: C, D
Publisher: name: Zenodo

description: We present a novel theoretical framework in which the Higgs field, coupled to an emergent antiHiggs measurement operator, governs mass-energy evolution and spacetime curvature via a HiggsZeno effect. This framework modifies Einstein’s equations by introducing a time-dependent massenergy evolution equation that influences gravitational dynamics. We explore the implications of thismodel on quantum measurement theory, black hole physics, and cosmology. The Higgs-Zeno effectintroduces modifications to the Higgs potential, impacts vacuum stability, and alters mass-energyconservation. We discuss experimental constraints from high-energy colliders, dark matter searches,and gravitational wave detectors. Numerical simulations of Higgs-Zeno mass decay and gravitationalmodifications are presented, along with their potential astrophysical and cosmological implications.This model provides a testable mechanism linking Higgs interactions with fundamental spacetimeproperties and may offer insight into black hole entropy dynamics and dark matter phenomenology.

description: raditional quantum gravity models struggle to integrate mass-energy evolution with measurement dynamics. Recent work, such as that by Misra and Sudarshan (1977) [2], Facchi and Pascazio(2008) [3], and Itano (2009) [4], examines the quantum Zeno effect’s influence on quantum systems.Our work extends this by introducing an anti-Higgs measurement operator Ψ and exploring its implications on spacetime curvature, dark matter relic production, and gauge-gravity unification. Wederive modified Einstein-Yang-Mills equations from a unified Lagrangian featuring Zeno-suppressedinteractions, demonstrate SU(5) gauge coupling unification with precision ∆g−2 < 0.1%, and calculate electroweak symmetry breaking corrections (∆vH/vH < 1%). The framework predicts testabledeviations in black hole evaporation (suppression factors ∼ 10−3), gravitational wave propagation(∆c/c ∼ 10−5), and dark matter direct detection (σΨ ∼ 10−49 cm2).

description: The peculiar band structure of semimetals exhibiting Dirac and Weyl crossings can lead to spectacular electronic properties such as large mobilities accompanied by extremely high magnetoresistance. In particular, two closely neighbouring Weyl points of the same chirality are protected from annihilation by structural distortions or defects, thereby significantly reducing the scattering probability between them. Here we present the electronic properties of the transition metal diphosphides, WP2 and MoP2, that are type-II Weyl semimetals with robust Weyl points. We present transport and angle resolved photoemission spectroscopy measurements, and first principles calculations. Our single crystals of WP2 display an extremely low residual low-temperature resistivity of 3 nohm-cm accompanied by an enormous and highly anisotropic magnetoresistance above 200 million % at 63 T and 2.5 K. These properties are likely a consequence of the novel Weyl fermions expressed in this compound. We observe a large suppression of charge carrier backscattering in WP2 from transport measurements.

description: Sentiment Analysis Systems (SASs) are data-driven Artificial Intelligence (AI) systems that output polarity and emotional intensity when given a piece of text as input. Like other AIs, SASs are also known to have unstable behavior when subjected to changes in data which can make it problematic to trust out of concerns like bias when AI works with humans and data has protected attributes like gender, race, and age. Recently, an approach was introduced to assess SASs in a blackbox setting without training data or code, and rating them for bias using synthetic English data. We augment it by introducing two human-generated chatbot datasets and also consider a round-trip setting of translating the data from one language to the same through an intermediate language. We find that these settings show SASs performance in a more realistic light. Specifically, we find that rating SASs on the chatbot data showed more bias compared to the synthetic data, and round-tripping using Spanish and Danish as intermediate languages reduces the bias (up to 68% reduction) in human-generated data while, in synthetic data, it takes a surprising turn by increasing the bias! Our findings will help researchers and practitioners refine their SAS testing strategies and foster trust as SASs are considered part of more mission-critical applications for global use.

Higgs-Zeno Spacetime: Quantum Measurement, Dual Hamiltonians, and Mass-Energy Evolution
Creators: name: C, D
Publisher: name: Zenodo
Year: 2025

description: The search for a unified theory of gravity and gauge interactions remains one of the most profound challenges in fundamental physics. In this work, we introduce the Higgs-Zeno effect as a novel mechanism that dynamically modifies spacetime curvature, leading to an emergent unification of Einstein’s gravity with gauge fields. By incorporating measurement-induced suppression terms into the Einstein-Yang-Mills framework, we derive modified renormalization group (RG) equations, demonstrating that Newton’s constant GGG evolves alongside gauge couplings at high-energy scales. This results in a precise unification of gravity and gauge forces at μUFT∼1018\mu_{\text{UFT}} \sim 10^{18}μUFT∼1018 GeV, offering a natural resolution to quantum gravity inconsistencies in grand unified theories (GUTs).

Furthermore, our framework predicts observable deviations in fundamental physics:

Gravitational wave speed modifications (Δc/c∼10−5\Delta c/c \sim 10^{-5}Δc/c∼10−5), potentially detectable by LISA.

Suppressed black hole evaporation rates (∼10−3\sim10^{-3}∼10−3 corrections to Hawking radiation), impacting black hole thermodynamics.

A dark matter candidate (Ψ\PsiΨ), consistent with XENONnT constraints, with a predicted direct detection cross-section of σΨ∼10−49 cm2\sigma_\Psi \sim 10^{-49} \text{ cm}^2σΨ∼10−49 cm2.

By bridging quantum measurement dynamics, gauge interactions, and spacetime geometry, the Higgs-Zeno effect provides a new pathway toward a unified quantum gravity framework with testable experimental consequences.

description: Let $W_{m|n}$ be the (finite) $W$-algebra attached to the principal nilpotent orbit in the general linear Lie superalgebra $\mathfrak{gl}_{m|n}(\mathbb{C})$. In this paper we study the {\em Whittaker coinvariants functor}, which is an exact functor from category $\mathcal O$ for $\mathfrak{gl}_{m|n}(\mathbb{C})$ to a certain category of finite-dimensional modules over $W_{m|n}$. We show that this functor has properties similar to Soergel's functor $\mathbb V$ in the setting of category $\mathcal O$ for a semisimple Lie algebra. We also use it to compute the center of $W_{m|n}$ explicitly, and deduce some consequences for the classification of blocks of $\mathcal O$ up to Morita/derived equivalence.
