description: In this paper, we analyze the scaling behavior of \emph{Diffusion Limited Aggregation} (DLA) simulated by Hastings-Levitov method. We obtain the fractal dimension of the clusters by direct analysis of the geometrical patterns in a good agreement with one obtained from analytical approach. We compute the two-point density correlation function and we show that in the large-size limit, it agrees with the obtained fractal dimension. These support the statistical agreement between the patterns and DLA clusters. We also investigate the scaling properties of various length scales and their fluctuations, related to the boundary of cluster. We find that all of the length scales do not have a simple scaling with same correction to scaling exponent. The fractal dimension of the perimeter is obtained equal to that of the cluster. The growth exponent is computed from the evolution of the interface width equal to $β=0.557(2)$. We also show that the perimeter of DLA cluster has an asymptotic multiscaling behavior.

L'analisi dei dati delle supernovae distanti ha portato due fisici dell’Università del Mississippi a concludere che l'Universo non solo si sta espandendo ma allo stesso tempo oscilla. I risultati, pubblicati su Astronomical Journal, suggeriscono che lo spazio sia passato da una fase di espansione rallentata ad una fase di espansione accelerata non una volta bensì 7 volte nel corso di 13,8 miliardi di anni
Global phase diagrams of frustrated quantum antiferromagnets in two dimensions: doubled Chern-Simons theory

description: We present a general approach to understanding the quantum phases and phase transitions of quantum antiferromagnets in two spatial dimensions. We begin with the simplest spin liquid state, the Z_2 spin liquid, whose elementary excitations are spinons and visons, carrying Z_2 electric and magnetic charges respectively. Their dynamics are expressed in terms of a doubled U(1) Chern-Simons theory, which correctly captures the `topological' order of the Z_2 spin liquid state. We show that the same theory also yields a description of the variety of ordered phases obtained when one or more of the elementary excitations condense. Field theories for the transitions and multicritical points between these phases are obtained. We also survey experimental results on antiferromagnets on the anisotropic triangular lattice, and make connections between their phase diagrams and our results.

Grazie ad un nuovo modello in tre dimensioni, sviluppato dalla NASA con un supercomputer, è stato possibile osservare le onde a spirale provocate dal passaggio di un pianeta all'interno del disco di detriti attorno alla stella Beta Pictoris e comprendere meglio il comportamento dei detriti stessi. Ora occorrerà cercare ancora per capire se il comportamento del disco sia influenzato dalla presenza di un altro pianeta ancora ignoto.

description: This paper presents the observation of the electroweak production of single top quarks in the D0 detector at the Fermilab Tevatron Collider at a center-of-mass energy of 1.96 TeV. Events containing an isolated electron or muon and missing transverse energy, together with jets originating from the fragmentation of b quarks are used to measure a cross section for single top quark production of sigma(ppbar -> tb + X, tqb + X) = 3.94 +- 0.88 pb. The probability to measure a cross section at this value or higher in the absence of signal is 2.5X10^-7, corresponding to a 5.0 standard deviation significance.

description: We place further restriction on the possible topology of stationary asymptotically flat vacuum black holes in 5 spacetime dimensions. We prove that the horizon manifold can be either a connected sum of Lens spaces and "handles" $S^1 \times S^2$, or the quotient of $S^3$ by certain finite groups of isometries (with no "handles"). The resulting horizon topologies include Prism manifolds and quotients of the Poincare homology sphere. We also show that the topology of the domain of outer communication is a cartesian product of the time direction with a finite connected sum of $\mathbb R^4,S^2 \times S^2$'s and $CP^2$'s, minus the black hole itself. We do not assume the existence of any Killing vector beside the asymptotically timelike one required by definition for stationarity.

description: This report presents the findings of a NIAC Phase I feasibility study for the Artemis-enabled Stellar Imager (AeSI), a proposed high-resolution, UV/Optical interferometer designed for deployment on the lunar surface. Its primary science goal is to image the surfaces and interiors of stars with unprecedented detail, revealing new details about their magnetic processes and dynamic evolution and enabling the creation of a truly predictive solar/stellar dynamo model. This capability will transform our understanding of stellar physics and has broad applicability across astrophysics, from resolving the cores of Active Galactic Nuclei (AGN) to studying supernovae, planetary nebulae, and the late stages of stellar evolution. By leveraging the stable vacuum environment of the Moon and the infrastructure being established for the Artemis Program, AeSI presents a compelling case for a lunar-based interferometer. In this study, the AeSI Team, working with the NASA Goddard Space Flight Center's Integrated Design Center (IDC), has firmly established the feasibility of building and operating a reconfigurable, dispersed aperture telescope (i.e., an interferometer) on the lunar surface. The collaboration produced a credible Baseline design featuring 15 primary mirrors arranged in an elliptical array with a 1 km major axis, with the potential to expand to 30 mirrors and larger array sizes through staged deployments. Additionally, this study identified numerous opportunities for optimization and the necessary trade studies to refine the design further. These will be pursued in follow-up investigations, such as a NIAC Phase II study, to advance the concept toward implementation.

description: We predict the energy per baryon in nuclear matter with non-zero fraction of $Λ$ hyperons. We include Dirac effects on the nucleons as well as the $Λ$ and describe how the latter is implemented. We use the nucleon-hyperon meson-exchange potentials from the Juelich group, the latest as well as an earlier version. The dependence of the results on the many-body framework and on the nucleon-hyperon interaction model is discussed.

description: We study the g-modes of fast rotating stratified neutron stars in the general relativistic Cowling approximation, where we neglect metric perturbations and where the background models take into account the buoyant force due to composition gradients. This is the first paper studying this problem in a general relativistic framework. In a recent paper by Passamonti et al.(2009), a similar study was performed within the Newtonian framework, where the authors presented results about the onset of CFS-unstable g-modes and the close connection between inertial- and gravity-modes for sufficiently high rotation rates and small composition gradients. This correlation arises from the interplay between the buoyant force which is the restoring force for g-modes and the Coriolis force which is responsible for the existence of inertial modes. In our relativistic treatment of the problem, we find an excellent qualitatively agreement with respect to the Newtonian results.

Social assistance administration in relation to dependency : a review of contemporary concepts of dependency and public welfare administration, with reference to the administration of the Social Assistance Act by the City of Vancouver Social Service Department
Creators: name: Macintyre, James McEwan
Publisher: name: University of British Columbia

description: The problem of the cost of dependency in public welfare has recently motivated many areas to make special studies to determine ways in which it might be reduced. The studies of Bradley Buell and associates have brought to the fore that in any community there is a comparatively small group of families which make use of the majority of health and welfare services in that community. This study was designed to determine the size of the dependency problem in Vancouver and to evaluate the public welfare agency's attempts at combatting any problem that might exist. After reviewing the history of public welfare and the treatment of assistance recipients, attention was directed toward present-day concepts and ways of combatting dependency in urban areas. The extent of the problem in Vancouver was examined by examining the numbers receiving private and public agency aid. Two public assistance caseloads were examined to determine how long the clients had been in receipt of assistance, why they were receiving it, and how old they were. The organization and facilities of the City Social Service Department were reviewed. Two research methods were employed: (1) reviewing the literature to determine how best to deal with the dependent group, and (2) statistical classification of two sample public agency caseloads and services given by private agencies. Information for this study was obtained from the Vancouver City Social Service Department records of assistance recipients, a Community Chest survey of the unemployed group in Vancouver, current literature, and personal observations. In recent years, between one and two per cent of the population of the City of Vancouver have had to rely on the Social Service Department for their economic livelihood. Most persons on assistance are medically unfit for work although some recipients get this aid as they have to look after dependent children or are unable to get an old person's allowance. Very good medical care is given clients, but the size of the caseloads is such that it is difficult for workers to spend much time with any one client to give continuing casework help. It has been found that to adequately combat dependency, the various social agencies in the community must work together. Individual diagnoses are needed to determine those who can be helped to become rehabilitated.

The Klauder-Daubechies Construction of the Phase Space Path Integral and the Harmonic Oscillator

description: The canonical operator quantisation formulation corresponding to the Klauder-Daubechies construction of the phase space path integral is considered. This formulation is explicitly applied and solved in the case of the harmonic oscillator, thereby illustrating in a manner complementary to Klauder and Daubechies' original work some of the promising features offered by their construction of a quantum dynamics. The Klauder-Daubechies functional integral involves a regularisation parameter eventually taken to vanish, which defines a new physical time scale. When extrapolated to the field theory context, besides providing a new regularisation of short distance divergences, keeping a finite value for that time scale offers some tantalising prospects when it comes to strong gravitational quantum systems.

description: The terrestrial vegetation GPP of Qinghai Province is an important variable that characterizes the carbon cycling pattern. However, there is still a lack of a high-resolution GPP dataset for Qinghai Province. To address this issue, we processed all Landsat images of Qinghai from 1987 to 2021 using the GEE, and we combined multi-source auxiliary data to estimate GPP using the revised EC-LUE model. We compared our GPP dataset with flux observations to verify its accuracy. The results showed that our GPP dataset had a high correlation with the flux tower observations, with correlation coefficients of 0.984 at CF-AM site and 0.976 at CN-Ha2 site, respectively, and each site had an RMSE of 11.960gC⋅m−2⋅16d−1 and 12.986 gC⋅m−2⋅16d−1, respectively. There are different deviations between our GPP dataset and the mainstream GPP datasets in various vegetation types, with the average correlation coefficient ranging from 0.431 to 0.943. By comparing with the flux observations and the related analysis, we demonstrated that our GPP dataset features better accuracy, higher spatial resolution, and more temporal coverage than mainstream GPP datasets. This study offers the first long-term high-resolution GPP dataset for Qinghai Province, and we believe that this dataset has important implications for ecological management and climate research.

description: Understanding individual differences and brain-behaviour relationships is an essential goal of human neuroscience. Recent studies have shown the great potential of naturalistic stimuli, e.g., movie clips, in advancing this pursuit. While the use of naturalistic stimuli attracts increasing interest, the influence of stimulus selection remains largely unclear. In this study, we show that brain activity is generally sensitive to the choice of movie stimuli at both group and individual subject levels. Using sex classification as an example, we demonstrate that brain activity elicited by different stimuli can lead to distinct prediction performance and unique predictive features. The stimuli that yield better classification performance often elicit stronger synchrony of brain activity across all subjects and are mostly derived from Hollywood films with rich social content and cohesive narratives. Our results highlight the importance of stimulus selection and provide practical guidance for choosing appropriate stimuli, opening up new avenues for future studies on individual differences and brain-behaviour relationships.

A Fully Quantum Asymptotic Equipartition Property

description: The classical asymptotic equipartition property is the statement that, in the limit of a large number of identical repetitions of a random experiment, the output sequence is virtually certain to come from the typical set, each member of which is almost equally likely. In this paper, we prove a fully quantum generalization of this property, where both the output of the experiment and side information are quantum. We give an explicit bound on the convergence, which is independent of the dimensionality of the side information. This naturally leads to a family of Renyi-like quantum conditional entropies, for which the von Neumann entropy emerges as a special case.

description: Stellar-mass black holes in the low-hard state may hold clues to jet formation and basic accretion disk physics, but the nature of the accretion flow remains uncertain. A standard thin disk can extend close to the innermost stable circular orbit, but the inner disk may evaporate when the mass accretion rate is reduced. Blackbody-like continuum emission and dynamically-broadened iron emission lines provide independent means of probing the radial extent of the inner disk. Here, we present an X-ray study of eight black holes in the low-hard state. A thermal disk continuum with a colour temperature consistent with $L \propto T^{4}$ is clearly detected in all eight sources, down to $\approx5\times10^{-4}L_{Edd}$. In six sources, disk models exclude a truncation radius larger than 10rg. Iron-ka fluorescence line emission is observed in half of the sample, down to luminosities of $\approx1.5\times10^{-3}L_{Edd}$. Detailed fits to the line profiles exclude a truncated disk in each case. If strong evidence of truncation is defined as (1) a non-detection of a broad iron line, {\it and} (2) an inner disk temperature much cooler than expected from the ${\rm L} \propto {\rm T}^{4}$ relation, none of the spectra in this sample offer strong evidence of disk truncation. This suggests that the inner disk may evaporate at or below $\approx1.5\times10^{-3}L_{Edd}$.

description: We investigate the properties of HI-rich galaxies detected in blind radio surveys within the hierarchical structure formation scenario using a semi-analytic model of galaxy formation. By drawing a detailed comparison between the properties of HI-selected galaxies and HI absorption systems, we argue a link between the local galaxy population and quasar absorption systems, particularly for Damped Ly-alpha absorption (DLA) systems and sub-DLA systems. First, we evaluate how many HI-selected galaxies exhibit HI column densities as high as those of DLA systems. We find that HI-selected galaxies with HI masses M(HI) > 10^8 solar masses have gaseous disks that produce HI column densities comparable to those of DLA systems. We conclude that DLA galaxies where the HI column densities are as high as those of DLA systems, contribute significantly to the population of HI-selected galaxies at M(HI) > 10^8 solar masses. Second, we find that star formation rates (SFRs) correlate tightly with HI masses rather than B- (and J-) band luminosities. In the low-mass range M(HI) < 10^8 solar masses, sub-DLA galaxies replace DLA galaxies as the dominant population. The number fraction of sub-DLA galaxies relative to galaxies reaches 40%-60% at HI masses 10^8 solar masses and 30%-80% at 10^7 solar masses. The HI-selected galaxies at 10^7 solar masses are a strong probe of sub-DLA systems that place stringent constraints on galaxy formation and evolution.

Un ricercatore della NASA ha realizzato una simulazione numerica per descrivere l'emissione di alta energia dovuta all'annichilazione delle particelle di materia oscura che si muovono nel campo gravitazionale di un buco nero ruotante. L'analisi dei dati implica che questo segnale caratteristico potrebbe essere rivelato in un futuro non molto lontano, man mano cioè che miglioreranno i telescopi che operano in banda gamma.

Casework in the return of non-ward care cases to the parental home : a descriptive and analytical study of Social Welfare Branch (British Columbia) cases, 1953-1956

description: "Non-ward Care” refers to a child for whom the Superintendent of Child Welfare has assumed responsibility temporarily at the request of the child’s parent or guardian. The primary function of non-ward care is the protection of children within their own family unit, the importance to the child of having his own parents accept responsibility for him being recognized as a principle basic to child welfare services. Non-ward care, as described in this thesis, is an important service for treating certain family situations in the hope that this treatment will make it possible for children and parents to help themselves. In the final analysis, the real assessment of the use of the resource of non-ward care depends on the preservation of the family unit. This study was undertaken in an attempt to examine descriptively and analytically the casework services involved in the provision of the resource of non-ward care to families, and to note how the families were being benefited by the resource. The analysis of the fifteen cases used in this study suggests some correlation between the evidence of improvement in the family situation and the quality of the social work methods and techniques exhibited by the worker during the course of the agency's contact with the family. This is judged by the rating of the progress made by the families as related to the quality of the worker's relationship, and also the extent to which basic social work methods and techniques were used by the worker. In both instances, the cases which showed much improvement in the family situation, showed proficient use of the basic social work methods and techniques. The cases which made little progress showed weaknesses in some areas of social work methods, particularly the areas which require diagnostic skill, evaluation, and the making of a plan based on the diagnosis. The findings of the study are that, in the majority of instances, the resource of non-ward care was being used towards the preservation of the families; and that, from the beginning the plan was for the children to be returned to their parents’ homes when the situation had been alleviated. There were a few cases, however, in which the original plan for the family seemed to have been lost sight of and children had remained in care longer than had been envisaged, while no improvement had occurred in the family situation. The implications here are significant not only for this type of service, but for all fields of the social work profession.

description: We observe the decays $ $D^*_{s1}(2710)^+ \to D^*K$ and $D^*_{sJ}(2860)^+ \to D^*K$ and measure their branching fractions relative to the $D K$ final state. We also observe, in the $D^*K$ mass spectrum, a new broad structure at a mass of $(3044 \pm 8_{stat} (^{+30}_{-5})_{syst})$ $MeV/c^2$ having a width $Γ=(239 \pm 35_{stat} (^{+46}_{-42})_{syst})$ $MeV$. To obtain this result we use 470 ${\rm fb}^{-1}$ of data recorded by the BaBar detector at the PEPII asymmetric-energy $e^+e^-$ storage rings at the Stanford Linear Accelerator Center running at center-of-mass energies near 10.6 GeV.

description: The discovery of neutrino masses has provided strong hints in favor of the possibility that B-L symmetry is an intimate feature of physics beyond the standard model. I discuss how important information about this symmetry as well as other scenarios for TeV scale new physics can be obtained from the baryon number violating process, neutron-anti-neutron oscillation. This article presents an overview of different aspects of neutron-anti-neutron oscillation and is divided into the following parts : (i) the phenomenon; (ii) the physics, (iii) plausible models and (iv) applications to cosmology. In particular, it is argued how the discovery of $n-\bar{n}$ oscillation can significantly affect our thinking about simple grand unified theory paradigms for physics beyond the standard model, elucidate the nature of forces behind neutrino mass and provide a new microphysical view of the origin of matter in the universe.

A Socio-hydrological Framework to Assess Rate Design for Urban Water Affordability through Drought

description: Unaffordable water threatens water access in the United States, particularly for low-income households that struggle to pay the rising cost for water. In water-scarce cities, water shortages necessitate either expensive infrastructure development or costly emergency measures to meet demand, which in turn increase household water costs. Rate design plays a key role in determining whether these costs threaten water affordability for low-income households, but water utilities are often constrained by local and state policy in their ability to set progressive rates. Therefore, new approaches to design rates that optimize water affordability within the local legal and hydrological context are needed in drought-prone regions. To address this gap, we design a socio-hydrological modeling framework that fuses legal analysis, behavioral economics, and hydrologic modeling to assess the impacts of rate design on household water affordability. We demonstrate this framework in an illustrative application in Santa Cruz, California, where droughts threaten water supplies and California Proposition 218 deters public water utilities in setting progressive rate design. Initial results demonstrate that flat drought surcharges reduce affordability, particularly under increasing block rate tariffs. This framework can both help utilities design rates to improve water affordability in their socio-hydrological context and also illuminate the impacts of state policy on affordability outcomes.
