description: Unique data on $BVRI$ brightness curves of the OT of GRB 970508 obtained with the 6-m telescope have been interpreted in the framework of the GRB-SN (supernovae) connection. The effect must be maximal in the I_c band as OT GRB 970228. The peak absolute (M_B) magnitude of the suggested SN must be around -19.5 for the OT of GRB 970508. If all or the main part of long GRBs are associated with SNe, the GRB host galaxies (for ground-based observations, at least) must be dimmer than the peak magnitude of the SN.

description: It is discussed that the usual Heisenberg commutation relation (CR) is not a proper relation for massless particles and then an alternative is obtained. The canonical quantization of the free electromagnetic(EM)fields based on the field theoretical generalization of this alternative is carried out. Without imposing the normal ordering condition,the vacuum energy is automatically zero.This can be considered as a solution to the EM fields vacuum catastrophe and a step toward managing the cosmologial constant problem at least for the EM fields contribution to the state of vacuum.

description: The optoelectronic properties of atomically thin transition-metal dichalcogenides are strongly correlated with the presence of defects in the materials, which are not necessarily detrimental for certain applications. For instance, defects can lead to an enhanced photoconduction, a complicated process involving charge generation and recombination in the time domain and carrier transport in the spatial domain. Here, we report the simultaneous spatial and temporal photoconductivity imaging in two types of WS2 monolayers by laser-illuminated microwave impedance microscopy. The diffusion length and carrier lifetime were directly extracted from the spatial profile and temporal relaxation of microwave signals respectively. Time-resolved experiments indicate that the critical process for photo-excited carriers is the escape of holes from trap states, which prolongs the apparent lifetime of mobile electrons in the conduction band. As a result, counterintuitively, the photoconductivity is stronger in CVD samples than exfoliated monolayers with a lower defect density. Our work reveals the intrinsic time and length scales of electrical response to photo-excitation in van der Waals materials, which is essential for their applications in novel optoelectronic devices.

description: Sufficiently high voltage applied between two metal electrodes, even in ultra high vacuum conditions, results in an inevitable discharge that lights up the entire gap, opening a conductive channel through the vacuum and parasitically consuming large amounts of energy. Despite many efforts to understand the processes that lead to this phenomenon, known as vacuum arc, there is still no consensus regarding the role of each electrode in the evolution of such a momentous process as lightning. Employing a high-speed camera, we capture the entire lightning process step-by-step with a nanosecond resolution and find which of the two electrodes holds the main responsibility for igniting the arc. The light that gradually expands from the positively charged electrode (anode), often is assumed to play the main role in the formation of a vacuum arc. However, both the nanosecond-resolution images of vacuum arc evolution and the corresponding theoretical calculations agree that the conductive channel between the electrodes is built in the form of cathodic plasma long before any significant activity develops in the anode. We show evidently that the anode illumination is weaker and plays a minor role in igniting and maintaining the conductive channel.
Illuminating the spiritual : the symbolic art of Christian Waller

description: Australian artist Christian Waller nee Yandell (1894-1954) created artworks that unified her aesthetic and spiritual values. The technical and expressive brilliance of her work across a range of art media - drawing, painting, illustration, printmaking, stained glass and mosaic - makes it worthy of focused scholarly attention. Important influences on her practice included Pre-Raphaelitism, Art Deco and the Celtic Revival. Her spirituality was informed by a range of orthodox and alternative systems of belief, including: Christianity, Theosophy, the Hermetic Order of the Golden Dawn and the international Peace Mission Movement. Acting as an emissary, she included personal symbols - especially the sun, the moon, stars and flowers - in her artworks to encourage spiritual contemplation. In this thesis, I argue that Waller harnessed the decorative and expressive potential of these movements - along with a commitment to Arts and Crafts values - to develop a personal set of symbols that expressed her sense of the spiritual. This encompassed the harmony of word, image and message, which underscored her work. It is for this reason that I locate Waller within the international discourse of spiritual art. Despite her remarkable talents across media and the distinctive quality of her art, Waller has always occupied a peripheral position within Australian art and art history. Even when she is included in significant books and exhibitions, most often it is in relation to her hand-printed book 'The Great Breath: A Book of Seven Designs' (1932) and her relationship with her husband, fellow artist Napier Waller. Key aims of this thesis are to highlight the breadth and depth of Waller's art practice and to demonstrate that she made important contributions to Australian art and to art that addresses the sacred.This thesis introduces a number of Waller's artworks, stories and personal ephemera into scholarship, making a comprehensive study of the artist possible for the first time. It makes a major contribution to scholarship on the artist, especially in relation to the spiritual values that underpinned her practice, as expressed in the key symbols that are identified. By extension, it contributes a more nuanced understanding of art produced between the First and Second World Wars to Australian art history and to scholarship on art that addresses the sacred.

description: We present a 13C and 133Cs NMR investigation of the CsC60 cubic quenched phase. Previous ESR measurements suggest that this phase is metallic, but NMR reveals contrasting electronic behavior on the local scale. The 13C spin-lattice relaxation time (T1) exhibits a typical metallic behavior down to 50 K, but indicates that a partial spin-gap opens for T<50 K. Unexpectedly, 133Cs NMR shows that there are two inequivalent Cs sites. For one of these sites, the NMR shift and (T1T)^{-1} follow an activated law, confirming the existence of a spin-gap. We ascribe this spin-gap to the occurrence of localized spin-singlets on a small fraction of the C60 molecules.

Studies in nuclear photodisintegration

Publisher: name: The Australian National University
Year: 1957
Subjects: photonuclear reactions

description: The transformations of nuclei following the absorption of photons would appear to have considerable advantages over the study of particle induced reactions for investigating nuclear structure. The chief features of the electromagnetic interaction are well understood, and the interaction is weak so that radiation may not disturb the nucleus under investigation as much as a particle reaction would. Hence one might hope that the photodisintegration process could be understood before other nuclear reactions. Unfortunately, there are difficulties on both the theoretical and experimental sides which rather offset these advantages,. the processes are expected to depend very sensitively on the details of the charge and current distribution inside the nucleus. This distribution depends not only on the nucleon motions but also, for the case of exchange forces, on the motion of the charged meson cloud. The determination of the nucleon motion is hindered by our present ignorance concerning nuclear forces and by the mathematical intractability of the many-body problem. A theoretical treatment of the exchange currents is even more difficult. (First paragraph of introduction).

description: Even moderate amounts of zero returns in financial data, associated with stale prices, are heavily detrimental for reliable jump inference. We harness staleness-robust estimators to re-appraise the statistical features of jumps in financial markets. We find that jumps are much less frequent and much less contributing to price variation than what found by the empirical literature so far. In particular, the empirical finding that volatility is driven by a pure jump process is actually shown to be an artifact due to staleness.

description: The present study examines participants of all weight statuses and their levels of weight stigma consciousness, self consciousness, depression, anxiety, stress, relationship satisfaction, and weight-based rejection sensitivity. The 263 participants (I 93 females and 70 males) had their physical and perceived weight statuses measured and the relationships with these variables with scores on the remaining variables were examined. Individuals with higher weight statuses are significantly more weight stigma conscious and more rejection sensitive in terms of weight. Also, higher levels of weight stigma consciousness were significantly related to higher levels of depression, anxiety, and stress, and lower levels of relationship satisfaction. Perceived weight status was shown to be a more accurate predictor of weight-based rejection sensitivity than physical weight status. These results provided support for the construct validity of the Weight Stigma Consciousness Questionnaire and Weight-Based Rejection Sensitivity Questionnaire.

description: In these lectures, a variety of non-equilibrium transport phenomena are introduced that all involve, in some way, elastic manifolds being driven through random media. A simple class of models is studied focussing on the behavior near to the critical ``depinning'' force above which persistent motion occurs in these systems. A simple mean field theory and a ``toy'' model of ``avalanche'' processes are analyzed and used to motivate the general scaling picture found in recent renormalization group studies. The general ideas and results are then applied to various systems: sliding charge density waves, critical current behavior of vortices in superconductors, dynamics of cracks, and simple models of a geological fault. The roles of thermal fluctuations, defects, inertia, and elastic wave propagation are all discussed briefly.

description: This is a critical account of three nouvelles or short stories by Samual Beckett entitled "L'Expulse", "Le Calmant" and "La Fin". The text discussed is the 1958 French version rather than the English translation "Stories" bearing the titles "The Expelled", "The Calmative" and "The End". The author does not summarise or paraphrase the stories but instead gives a critical account in which the more important aspects of the individual nouvelles are discussed in their order of appearance. The most frequently recurring topics are: the range of subject-matter; the incidence of satire; the attitude of story-telling; and the control of sympathy. Unlike former criticism, this essay is based on a conviction that the Nouvelles, though difficult, are ordered and intelligible. A coherent interpretation of "Le Calmant" is advanced which greatly simplifies the discussion of the Nouvelles as a whole.

description: New experiments that measure the low-frequency shot-noise spectrum at local tunneling contacts on mesoscopic structures are proposed. The current fluctuation spectrum at a single tunneling tip is determined by local partial densities of states. The current-correlation spectrum between two tunneling tips is sensitive to non-diagonal density of states elements which are expressed in terms of products of scattering states of the conductor. Thus such an experiment permits to investigate correlations of electronic wave functions. We present specific results for a clean wire with a single barrier and for metallic diffusive conductors.

description: We implement a Becke fuzzy cells type space partitioning scheme for the purposes of exchange-correlation within the GPAW projector augmented-wave method based density functional theory code. Space partitioning is needed in the situation where one needs to treat different parts of a combined system with different exchange-correlation functionals. For example, bulk and surface regions of a system could be treated with functionals that are specifically designed to capture the distinct physics of those regions. Here we use the space partitioning scheme to implement the quasi-nonuniform exchange-correlation scheme, which is a useful practical approach for calculating metallic alloys on the generalized gradient approximation level. We also confirm the correctness of our implementation with a set of test calculations.

description: We present one of the results of $BVRI$ photometry of the hosts of GRB for the host galaxy of GRB 970508 and the theoretical modeling of its continuum spectral energy distribution (SED) to show that it is important to take into account internal extinction in the host galaxies. We compared the BVRI broad-band flux spectrum of the host to template SEDs of local starburst galaxies and found that there is a significant internal extintion in this host. Moreover, this comparison allows us to derive the absolute magnitude (M_{B_{rest}}) and rouhgly estimate reddening (A_V). Population synthesis modeling of the continuum SED for different reddening laws demostrates that the observational data of the host galaxy of GRB 970508 are best fitted by the spectral properties of a model SED with extinction of A_V\approx 2.

description: nfdi.software Deliverable 3.1

To ensure connectivity and interoperability between nfdi.software and consortia specific marketplaces on the one hand and other basic services of NFDI on the other hand, WP3 aims to determine a common metadata schema for the description of research software. In preparation for the work on a common metadata schema/layer for nfdi.software, the goal of deliverable 3.1 is to provide an overview of relevant metadata schemas (and available crosswalks) of the different NFDI consortia and of NFDI basic services. 

The results of this deliverable are largely based on a) a 2024 survey on research software metadata in the NFDI Consortia, conducted by the working group on research software metadata within by the section RS Meta of the NFDI and, b) a 2025 survey carried out in the context of nfdi.software (WP2.2). Additionally, c) further information on software metadata schemas and formats used in other basic services was taken from publications. While the first survey gave us an in-depth picture of the state of software metadata within NFDI, the second survey provided a broader look on metadata schemas and vocabularies used. Additional research publications were taken into account to cover potential blind spots.
Detection of variable frequency signals using a fast chirp transform

description: The detection of signals with varying frequency is important in many areas of physics and astrophysics. The current work was motivated by a desire to detect gravitational waves from the binary inspiral of neutron stars and black holes, a topic of significant interest for the new generation of interferometric gravitational wave detectors such as LIGO. However, this work has significant generality beyond gravitational wave signal detection. We define a Fast Chirp Transform (FCT) analogous to the Fast Fourier Transform (FFT). Use of the FCT provides a simple and powerful formalism for detection of signals with variable frequency just as Fourier transform techniques provide a formalism for the detection of signals of constant frequency. In particular, use of the FCT can alleviate the requirement of generating complicated families of filter functions typically required in the conventional matched filtering process. We briefly discuss the application of the FCT to several signal detection problems of current interest.
Physical properties of galactic RV Tauri stars from Gaia DR2 data

description: We present the first period-luminosity and period-radius relation of Galactic RV Tauri variable stars. We have surveyed the literature for all variable stars belonging to this class and compiled the full set of their photometric and spectroscopic measurements. We cross-matched the final list of stars with the Gaia DR2 database and took the parallaxes, G-band magnitudes and effective temperatures to calculate the distances, luminosities and radii using a probabilistic approach. As it turned out, the sample was very contaminated and thus we restricted our study to those objects for which the RV Tau-nature was securely confirmed. We found that several stars are located outside the red edge of the classical instability strip, which implies a wider pulsational region for RV Tau stars. The period-luminosity relation of galactic RV Tauri stars is steeper than that of the shorter-period Type II Cepheids, in agreement with previous result obtained for the Magellanic Clouds and globular clusters. The median masses of RVa and RVb stars were calculated to be 0.45-0.52 M$_{\odot}$ and 0.83 M$_{\odot}$, respectively.

description: For systems of nonlinear equations f=0 with singular Jacobian Vf(x*) at some solution x* E F-1(0) the behaviour of Newton's method is analysed. Under certain regularity condition Q-linear convergence is shown to be almost sure from all initial points that are sufficiently c,lose to x*. The possibility of significantly better performance by other nonlienar equation solvers is ruled out. Instead convergence acceleration is achieved by variation of the stepsize or Richardson extrapolation. If the Jacobian Vf of a possibly undetermined system is know to have a nullspace of a certain dimensional a solution of interest, and overdetermined system based on the QR or LU decomposition of Vf is used to obtain superlinear convergence.

Their structures were elucidated by spectroscopic analysis, and the absolute configurations of 1a/1b were determined by CD analysis. All compounds were examined for their inhibitory effects on the nitric oxide (NO) production induced by lipopolysaccharide (LPS) in BV-2 microglial cells, and compounds 7–10 exhibited pronounced inhibition on NO production with IC50 values in the range of 5.8–10.2 μM, being more active than the positive control, quercetin (IC50 = 17.0 μM).

description: Water occupies a position of utmost importance as a fundamental natural resource of our planet, profoundly influencing our daily existence. A wide array of sources furnishes us with accessible water, encompassing precipitation, subterranean aquifers, and an assortment of surface water features like ponds, rivers, and lakes. Surface water bodies and wetlands play a critical role in the global ecosystem, offering a variety of vital ecological services, including water purification, carbon sequestration, and the provision of habitats for wildlife.

Surface water bodies play a crucial role as essential freshwater resources, benefiting both human and ecological systems. They are vital for sustaining all forms of life. Water safeguards biodiversity in riparian and wetland ecosystems by offering habitats to diverse flora and fauna. Beyond being a cornerstone of the hydrologic cycle, water profoundly influences various aspects of human life, including drinking water, agriculture, electricity generation, transportation, and industry (Huang et al. 2018; Bhattacharjee et al. 2021). Land surface water bodies, including rivers, lakes, swamps, and reservoirs, play a vital role in Earth's water cycle, exerting a significant impact on the global ecosystem and climate (Ali et al. 2019). However, a complex interplay emerges among sectors contending for this priceless commodity, spanning agriculture, infrastructure, domestic utilization, and industry. At the forefront of these sectors is agriculture, which accounts for a substantial share of water consumption (Rana and Neeru, 2017).

The fields are located at Galactic latitudes | b | >= 15deg and in various directions on the sky. We consider models for the structure of the Galaxy with different choices for the main parameters governing the shape and luminosity function of the thick disk and stellar halo. Comparing model predictions with the observed colour-magnitude diagram we are able to rule out an increasing or flat stellar luminosity function at the low-luminosity end. We also rule out large values of the vertical scale height of the thick disc, z_0, finding it to be in the range 800 <= z_0 <= 1200 pc. As for the local density normalization, values within the range 4 % <= n_0 <= 8 % seem to better reproduce the data. Our data essentially rule out a flattened stellar halo (c/a

From Ctenomys and Poephagomys the present genus is readily distinguished, by the comparatively large size of the ears, the small delicate claws, and smaller size of the inci ­ sors; and from Octodon by the uniform length of the hairs on the tail.
 " In the structure of the feet the genus Abrocoma approaches very nearly to Octodon, not only in the form, but in having the soles both of the fore and hind feet (which are devoid of hair) covered with mi ­ nute round fleshy tubercles. In Octodon, however, the toes have on their under side transverse incisions as observed in the Muridoe, a character, however, not found in Abrocoma; here the under side of the toes is, like the sole of the foot, covered with tubercles.
 " The extreme softness of the fur of the animals about to be de ­ scribed, suggested for them the generic name of Abrocoma. The fur consists of hairs of two lengths, and the longer hairs are so ex ­ tremely slender that they might almost be compared to the web of the spider. The specific names applied are those of the distinguished naturalists who first made us acquainted with the two genera Octo ­ don and Poephagomys, these being very nearly allied to Abrocoma.”

Simulating Forces - Learning Through Touch, Virtual Laboratories

description: With the expansion of e-learning course curricula and the affordability of haptic devices, at-home virtual laboratories are emerging as an increasingly viable option for e-learners. We outline three novel haptic simulations for the introductory physics concepts of friction, the Coriolis Effect, and Precession. These simulations provide force feedback through one or more Novint Falcon devices, allowing students to "feel" the forces at work in a controlled learning environment. This multi-modal approach to education (beyond the audiovisual) may lead to increased interest and immersion for e-learners and appeal to the kinesthetic learners who may struggle in a traditional e-learning course setting.
Three concepts of probability

description: Early probability theorists often spoke of probability in a way that was ambiguous between two different concepts of probability: a subjective concept and an objective concept. Subsequent theorists distinguished these two concepts from another, defining the subjective concept as the “uncertainty of an individual”, and the objective concept as a kind of “uncertainty in the world”. While these two concepts were distinguished from one another, some theorists believed that there was no such thing as “uncertainty in the world”, and that the only type of probability is subjective probability. The advent of quantum mechanics changed this orthodoxy. Here, for the first time—or so it has been argued—a scientific theory described the world as irreducibly probabilistic, using an objective concept of probability. While there have been authors who have levelled serious objections to this view, it has nonetheless been fairly popular. Scientific theories, however, were probabilistic long before quantum mechanics was developed. Perhaps the two most prominent cases in point were the fields of classical statistical mechanics and evolutionary theory. These two fields made use of probability theory in a way that looked objective, but often with the assumptions that the world is not irreducibly probabilistic, and that for there to be genuine “uncertainty in the world”, the world has to be irreducibly probabilistic. This caused many authors to wonder just what the probabilities in these fields could be representing. Proposed solutions to this puzzle have often been in the form of shoe-horning the probabilities of these fields into either the “uncertainty in the world” concept or the “uncertainty of an individual” concept—both with unsatisfactory consequences. In this dissertation, I investigate how we should understand the probabilities of classical statistical mechanics and evolutionary theory. To do this, I engage with arguments in the contemporary literature, and conclude that the probabilities of these two fields should be understood as neither the subjective concept of probability, nor the objective concept—standardly conceived. I argue that in order to develop an adequate account of these probabilities, we need to distinguish a third concept of objective probability that has nothing to do with “uncertainty”, whether it be in the world or of an individual. I then give an analysis of this third concept of probability.

description: Microscopic theory of the type of Efetov's supermatrix sigma-model is constructed for the low-lying electron states in a mixed superconductive-normal system with disorder. The developed technique is used for the study of the localized states in the core of a vortex in a moderately clean superconductor (1/Δ<< τ<< 1/ω_0 = E_F/Δ^2). At sufficiently low energies E << ω_{Th}, the energy level statistics is described by the "zero-dimensional" limit of this supermatrix theory, with the effective "Thouless energy" ω_{Th} \sim (ω_0/τ)^{1/2}. Within this energy range the result for the density of states is equivalent to that obtained within Altland-Zirnbauer random matrix model of class C. Nonzero modes of the sigma-model increase the mean interlevel distance ω_0 by the relative amount of the order of [2\ln(1/ω_0τ)]^{-1}.

description: Recently 2+1 dimensional gravity theory, especially ${\rm AdS_3}$ has been studied extensively. It was shown to be equivalent to the 2+1 Chern-Simon theory and has been investigated to understand the black hole thermodynamics, i.e. Hawking temperature and others. The purpose of this report is to investigate the canonical formalism of the original 2+1 Einstein gravity theory instead of the Chern-Simon theory. For the spherically symmetric space-time, local conserved quantities(local mass and angular momentum) are introduced and using them canonical quantum theory is defined. Constraints are imposed on state vectors and solved analytically. The strategy to obtain the solution is followed by our previous work.

description: We evaluate the theoretical uncertainties in next-to-leading order plus parton shower predictions for top quark pair production and decay in hadronic collisions. Our work is carried out using the Herwig 7 event generator and presents an in-depth study of variations in matching schemes with two systematically different shower algorithms, the traditional angular-ordered and alternative dipole shower. We also present all of the required extensions of the Herwig dipole shower algorithm to properly take into account quark mass effects, as well as its ability to perform top quark decays. The predictions are compared at parton level as well as to LHC data, including in the boosted regime. We find that the regions where predictions with a non-top-quark-specific tune differ drastically from data are plagued by large uncertainties which are consistent between our two shower and matching algorithms.
