description: Future or ongoing galaxy redshift surveys can put stringent constraints on neutrinos masses via the high-precision measurements of galaxy power spectrum, when combined with cosmic microwave background (CMB) information. In this paper we develop a method to model galaxy power spectrum in the weakly nonlinear regime for a mixed dark matter (CDM plus finite-mass neutrinos) model, based on perturbation theory (PT) whose validity is well tested by simulations for a CDM model. In doing this we carefully study various aspects of the nonlinear clustering and then arrive at a useful approximation allowing for a quick computation of the nonlinear power spectrum as in the CDM case. The nonlinear galaxy bias is also included in a self-consistent manner within the PT framework. Thus the use of our PT model can give a more robust understanding of the measured galaxy power spectrum as well as allow for higher sensitivity to neutrino masses due to the gain of Fourier modes beyond the linear regime. Based on the Fisher matrix formalism, we find that BOSS or Stage-III type survey, when combined with Planck CMB information, gives a precision of total neutrino mass constraint, sigma(m_nu,tot) 0.1eV, while Stage-IV type survey may achieve sigma(m_nu,tot) 0.05eV, i.e. more than a 1-sigma detection of neutrino masses. We also discuss possible systematic errors on dark energy parameters caused by the neutrino mass uncertainty. The significant correlation between neutrino mass and dark energy parameters is found, if the information on power spectrum amplitude is included. More importantly, for Stage-IV type survey, a best-fit dark energy model may be biased and falsely away from the underlying true model by more than the 1-sigma statistical errors, if neutrino mass is ignored in the model fitting.

Working mother's psychological well-being : a qualitative study investigating experiences across multiple domains of life
Creators: name: Edmunds, CM
Publisher: name: University Of Tasmania
Year: 2023

description: Research investigating the effect of working mother's increasing involvement in multiple domains of life typically assumes that negative experiences from work and family domains accumulate to detrimentally affect well-being (Tingey, Kinger, & Riley, 1996). The aim of the present study was to investigate how working mothers' positive and negative experiences across multiple roles (e.g. work, home, sport, religion) interact to have cumulative, compensatory or segmented influences on their well-being. The lack of existing literature in this area and the need to accommodate a comprehensive conceptualisation of working mothers' multifaceted life experiences necessitated a qualitative process of analysis. Using a social constructionist epistemology data was obtained from individual, semi-structured interviews with 22 working mothers from four organisations across Tasmania and Victoria. Interviews were analysed according to the principles of Braun and Clark's (2006) six-phase thematic analysis process. Findings revealed that working mother's well-being was influenced by an association between their Type A or Type B personality characteristics and interpersonal relationship conflict or satisfaction. Results further identified that these constructs mediated, or were mediated by working mothers' cumulative, compensatory or segmented experiences across work, home, social and personal roles. The implications of these findings for theory development and intervention design are discussed.

description: We present a theoretical study of elastic spin-dependent electron scattering caused by a charged impurity in the vicinity of a two-dimensional electron gas. We find that the symmetry properties of the spin-dependent differential scattering cross section are different for an impurity located in the plane of the electron gas and for one at a finite distance from the plane. We show that in the latter case asymmetric (`skew') scattering can arise if the polarization of the incident electron has a finite projection on the plane spanned by the normal vector of the two-dimensional electron gas and the initial propagation direction. In specially preparated samples this scattering mechanism may give rise to a Hall-like effect in the presence of an in-plane magnetic field.

description: We discuss observational evidence that quasars play a key role in the formation of galaxies starting from the detailed study of the quasar HE0450-2958 and extending the discussion to a series of converging evidence that radio jets may trigger galaxy formation. The direct detection with VISIR at the ESO-VLT of the 7 kpc distant companion galaxy of HE0450-2958 allows us to spatially separate the sites of quasar and star formation activity in this composite system made of two ultra-luminous infrared galaxies (ULIRGs). No host galaxy has yet been detected for this quasar, but the companion galaxy stellar mass would bring HE0450-2958 in the local M(BH)-M(stellar bulge) relation if it were to merge with the QSO. This is bound to happen because of their close distance (7 kpc) and small relative velocity (~60-200 km/s). We conclude that we may be witnessing the building of the M(BH)-M(stellar bulge) relation, or at least of a major event in that process. The star formation rate (~340 Msun/yr), age (40-200 Myr) and stellar mass ([5-6]x10^10 Msun) are consistent with jet-induced formation of the companion galaxy. We suggest that HE0450-2958 may be fueled in fresh material by cold gas accretion from intergalactic filaments. We map the projected galaxy density surrounding the QSO as a potential tracer of intergalactic filaments and discuss a putative detection. Comparison to other systems suggests that inside-out formation of quasar host galaxies and jet-induced galaxy formation may be a common process. Two tests are proposed for this new paradigm: (1) the detection of offset molecular gas or dust emission with respect to the position of distant QSOs, (2) the delayed formation of host galaxies as a result of QSO activity, hence the two step building of the M(BH)/M(stellar bulge) ratio.

description: In computational molecular biology, gene regulatory binding sites prediction in whole genome remains a challenge for the researchers. Now a days, the genome wide regulatory binding site prediction tools required either direct pattern sequence or weight matrix. Although there are known transcription factor binding sites databases available for genome wide prediction but no tool is available which can construct different weight matrices as per need of user or tools available for large data set scanning by first aligning the input upstream or promoter sequences and than construct the matrices in different level and file format. Considering this, we developed a DNA MATRIX tool for searching putative regulatory binding sites in gene upstream sequences. This tool uses the simple biological rule based heuristic algorithm for weight matrix construction, which can be transformed into different formats after motif alignment and therefore provides the possibility to identify the most potential conserved binding sites in the regulated genes. The user may construct and save specific weight or frequency matrices in different form and file formats based on user based selection of conserved aligned block of short sequences ranges from 6 to 20 base pairs and prior nucleotide frequency before weight scoring.

description: We show that strategy independent adaptations of random interaction networks can induce powerful mechanisms, ranging from the Red Queen to group selection, that promote cooperation in evolutionary social dilemmas. These two mechanisms emerge spontaneously as dynamical processes due to deletions and additions of links, which are performed whenever players adopt new strategies and after a certain number of game iterations, respectively. The potency of cooperation promotion, as well as the mechanism responsible for it, can thereby be tuned via a single parameter determining the frequency of link additions. We thus demonstrate that coevolving random networks may evoke an appropriate mechanism for each social dilemma, such that cooperation prevails even by highly unfavorable conditions.

A basic economic case for reordering the patent market with gain-based remedies
Creators: name: Abdussalam, MA
Publisher: name: University Of Tasmania
Year: 2023

description: There is a sizeable disparity between the advantages enabled by patent law remedies and the underlying rationale for the patent system. Furnishing solutions to the problem of patent opportunism, which is a product of this gap, is the singular purpose of this thesis. The nexus between patent remedies and the utilitarian social welfare goals of the patent system appears to have been understudied in major patent law jurisdictions, including Australia, Canada and the United Kingdom (UK). In these jurisdictions, focus has been placed more on managing the problems of the patent system attributable to patent law remedies, rather than addressing, head on, the nature of those remedies. This is not, however, the case in the United States of America (USA) where judges, government agencies and academics have expressed ongoing concerns over the tendency of patent law remedies to impact negatively on the social welfare goals of the patent system. Notwithstanding these articulated concerns, the fundamental reason for this negative tendency has been poorly identified, and recommendations to reform patent law remedies in response to it have been equally inadequate. Ted Sichelman's work titled 'Purging Patents of Private Law Remedies' ((2014) 92 Texas Law Review 528) and that of David Opderbeck titled 'Patent Damages and the Shape of Patent Law' ((2009) 89 Boston University Law Review 127) are a timely and valuable response to this problem. Both Sichelman and Opderbeck rightly blame patent opportunism on the ideological dissonance between the purpose of the patent system and the regime of legal remedies applied towards patent infringement. However, both scholars differ in their postulations of solutions to the problem. Sichelman has not yet put forward workable recommendations on how to replace the current remedies (particularly monetary remedies) prevailing in most patent law jurisdictions, with a view to reflecting the utilitarian nature of patents. Opderbeck suggests solutions that are workable but improvable. This thesis adds to the works of Sichelman and Opderbeck by postulating gain-based remedies‚ÄövÑvÆchiefly disgorgement and restitutionary reasonable royalties‚ÄövÑvÆ as the most pertinent species of monetary remedies suitable to furthering the utilitarian nature and objectives of patent entitlements. It is the submission of this thesis that these species of remedies will be effectual in stemming the tide of patent opportunism by changing the incentives of economic entities within the patent market, and correcting problems that emanate from the patent market's illiquidity.

description: Clustering in the luminosity of the afterglows of gamma-ray burst has been reported in the optical and X-ray. We investigate the possibility that a clustering in the luminosity of the afterglows of gamma-ray burst exists in near infrared (J, H, K bands). We use observations of events occurring from 1997 to the end of 2007. We correct the gamma-ray burst afterglow light curve for distance effect and time dilation, and replace all light curves to a common distance of z=1. We used only observations of signal emitted in the near infrared (in the burst frame). We observe a clustering identical to the one observed in optical and similar to the one observed in X-ray. We thus confirm the previous works made in optical. We set a constraint on the total energy of the fireball.

description: We search for ongoing major dry-mergers in a well selected sample of local Brightest Cluster Galaxies (BCGs) from the C4 cluster catalogue. 18 out of 515 early-type BCGs with redshift between 0.03 and 0.12 are found to be in major dry-mergers, which are selected as pairs (or triples) with $r$-band magnitude difference $\dm<1.5$ and projected separation $\rp<30$ kpc, and showing signatures of interaction in the form of significant asymmetry in residual images. We find that the fraction of BCGs in major dry-mergers increases with the richness of the clusters, consistent with the fact that richer clusters usually have more massive (or luminous) BCGs. We estimate that present-day early-type BCGs may have experienced on average $\sim 0.6 (\tmerge/0.3\Gyr)^{-1}$ major dry-mergers and through this process increases their luminosity (mass) by $15% (\tmerge/0.3\Gyr)^{-1} (\fmass/0.5)$ on average since $z=0.7$, where $\tmerge$ is the merging timescale and $\fmass$ is the mean mass fraction of companion galaxies added to the central ones. We also find that major dry-mergers do not seem to elevate radio activities in BCGs. Our study shows that major dry-mergers involving BCGs in clusters of galaxies are not rare in the local Universe, and they are an important channel for the formation and evolution of BCGs.

description: The formal mathematical theory of fair division has a rich history dating back at least to Steinhaus in the 1940's. In recent work in this area, several general classes of errors have appeared along with confusion about the necessity and sufficiency of certain hypotheses. It is the purpose of this article to correct the scientific record and to point out with concrete examples some of the pitfalls that have led to these mistakes. These examples may serve as guideposts for future work.

description: We use the probability distribution function (PDF) of the lya forest flux at z=2-3, measured from high-resolution UVES/VLT data, and hydrodynamical simulations to obtain constraints on cosmological parameters and the thermal state of the intergalactic medium (IGM) at z 2-3. The observed flux PDF at z=3 alone results in constraints on cosmological parameters in good agreement with those obtained from the WMAP data, albeit with about a factor two larger errors. The observed flux PDF is best fit with simulations with a matter fluctuation amplitude of sigma_8=0.8-0.85 \pm 0.07 and an inverted IGM temperature-density relation (gamma ~ 0.5-0.75), consistent with our previous results obtained using a simpler analysis. These results appear to be robust to uncertainties in the quasar (QSO) continuum placement. We further discuss constraints obtained by a combined analysis of the high-resolution flux PDF and the power spectrum measured from the Sloan Digital Sky Survey (SDSS) lya forest data. The joint analysis confirms the suggestion of an inverted temperature-density relation, but prefers somewhat higher values (sigma_8 ~ 0.9) of the matter fluctuation amplitude than the WMAP data and the best fit to the flux PDF alone. The joint analysis of the flux PDF and power spectrum (as well as an analysis of the power spectrum data alone) prefers rather large values for the temperature of the IGM, perhaps suggesting that we have identified a not yet accounted for systematic error in the SDSS flux power spectrum data or that the standard model describing the thermal state of the IGM at z ~ 2-3 is incomplete.

description: In this Closer Look, we consider current trends in shareholder activism and their potential impact. We examine the introduction of universal proxies, the increase in “activism experience” among directors, and the changing strategies of activists. With the regulatory and market environments in flux, we consider whether the balance of power is shifting, and, if so, toward whom. We ask: With the adoption of universal proxy, will boards become more accountable for performance or will responsible boards be caught up in unnecessary campaigns? Will proxy advisory firms be effective arbiters of board quality when comparing candidates? How does previous experience with activism campaigns change board preparedness? How is specialization and competition among activist funds influencing the tactics they employ against targets?

description: We have analyzed the first 3.75 years of data from TAOS, the Taiwanese American Occultation Survey. TAOS monitors bright stars to search for occultations by Kuiper Belt Objects (KBOs). This dataset comprises 5e5 star-hours of multi-telescope photometric data taken at 4 or 5 Hz. No events consistent with KBO occultations were found in this dataset. We compute the number of events expected for the Kuiper Belt formation and evolution models of Pan & Sari (2005), Kenyon & Bromley (2004), Benavidez & Campo Bagatin (2009), and Fraser (2009). A comparison with the upper limits we derive from our data constrains the parameter space of these models. This is the first detailed comparison of models of the KBO size distribution with data from an occultation survey. Our results suggest that the KBO population is comprised of objects with low internal strength and that planetary migration played a role in the shaping of the size distribution.

description: We discuss how classical straightedge and compass constructions can be ported to manifold surfaces under the geodesic metric. After defining the equivalent tools in the manifold domain, we analyze the most common constructions and show what happens when trying to port them to surfaces. Most such constructions fail, because the geometric properties on which they rely no longer hold under the geodesic metric. We devise some alternative constructions that guarantee at least some of the properties of their Euclidean counterpart; while we show that it is usually impossible to guarantee all properties together. Some constructions remain still unsolved, unless additional tools are used, which violate the constraints of the straightedge and compass framework since they take explicit distance measures. We integrate our constructions in the context of a prototype system that supports the interactive drawing of vector primitives on a surface represented with a high-resolution mesh.

Sustainable heritage and 'shop-top living' : the past and future of Launceston

Year: 2023

description: heritage led regeneration raises aspirations‚ÄövÑvp -- HRH Prince Charles - Dumfries House, Britain's Hidden Heritage (BBC One, 2011) A great city is vibrant and dynamic because of the people who live in it. For the city of Launceston, a restorative tonic can be found in a return to living 'above the shop' lost due to societal change and successive urban planning strategies designed to improve public health and safety outcomes. This research project demonstrates the complexity of 'shop-top living' and that all the internalities and externalities at work within the city have affected shops and shopping. Launceston is perfect for examining urban planning and design coupled with heritage revitalization and also government and private spending on significant development projects. The City of Launceston's significant heritage values greatly impact enabling measures and implementation schemes for urban regeneration. An understanding of both the retail and urban planning history of Launceston provides the background to the problems and issues of today with restoring both the form and function that 'shop-top living' affords. This study aims to ascertain stakeholder objectives and priorities to provide recommendations on fostering the right planning and cultural environment for success in revitalising both the city of Launceston and conserving its unique history and rich built heritage. This research project found that there were significant benefits for the city with an increase in the number of people living in the centre of the city. This includes liveability and place-remaking which effects how happy people are to live in a place as well as providing the associated health benefits from a safe and walkable place for people to live. With this city renewal the value and purpose will lead to an increase in the restoration and conservation of the built heritage of Launceston. This study also determined that there were some less than desirable outcomes for the people and heritage of Launceston such as gentrification, the possibility of the loss of heritage and the potential for conflict between retail and commercial entities and residents due to differing expectations of amenity and service. Further research is recommended to better quantify the benefits of enabling measures for 'shop-top living' with respect to the number and quality of properties which could be repurposed, acceptable (by community standards) heritage re-purposing and urban design outcomes, as well as the economic tools for facilitating uptake and potential environmental issues and/or impacts. There is also room for a more comprehensive analysis of current and proposed 'shop-top living' occurrences in Launceston.

description: We report the clear detection of the 2175A dust absorption feature in the optical afterglow spectrum of the gamma-ray burst (GRB) GRB070802 at a redshift of z=2.45. This is the highest redshift for a detected 2175A dust bump to date, and it is the first clear detection of the 2175A bump in a GRB host galaxy, while several tens of optical afterglow spectra without the bump have been recorded in the past decade. The derived extinction curve gives A_V=0.8-1.5 depending on the assumed intrinsic slope. Of the three local extinction laws, an LMC type extinction gives the best fit to the extinction curve of the host of GRB070802. Besides the 2175A bump we find that the spectrum of GRB070802 is characterized by unusually strong low-ionization metal lines and possibly a high metallicity for a GRB sightline ([Si/H]=-0.46+/-0.38, [Zn/H]=-0.50+/-0.68). In particular, the spectrum of GRB070802 is unique for a GRB spectrum in that it shows clear CI absorption features, leading us to propose a correlation between the presence of the bump and CI. The gas to dust ratio for the host galaxy is found to be significantly lower than that of other GRB hosts with N(HI)/A_V=(2.4+/-1.0)x10^21 cm^-2 mag^-1, which lies between typical MW and LMC values. Our results are in agreement with the tentative conclusion reached by Gordon et al. 2003 that the shape of the extinction curve, in particular the presence of the bump, is affected by the UV flux density in the environment of the dust.

The project asked people working, studying or volunteering in the archaeological world to participate in a 'Day of Archaeology' each year by recording their day and sharing it through text, images or video on the Day of Archaeology blog.
The project asked anyone with a personal, professional or voluntary interest in archaeology to get involved, and help highlight the reasons why archaeology is vital to protect the past and inform our futures. The resulting Day of Archaeology project archive demonstrates the wide variety of work the archaeological profession undertakes day-to-day across the globe, and helps to raise public awareness of the relevance and importance of archaeology to the modern world.
The first ever Day of Archaeology was held in 2011 and, since then, the project had thousands of archaeologists take part in the event, from those working in the field through to specialists working in laboratories and behind computers. The last Day of Archaeology was on Friday 28th July 2017.
Mirrored resonance : exploring an aesthetics of engagement
Creators: name: van der Beek, SM
Publisher: name: University Of Tasmania
Year: 2023

description: The aim of this project is to explore the appearing of the world; the manner in which the ordinary, everyday world is 'there' for a perceiving subject. This philosophical enquiry is undertaken through a phenomenological approach to photographic practice which explores looking as a participatory and embodied form of engagement with the world. The project takes light as evidence of the appearing world. I work with a precisely organised photographic apparatus to make light, rather than the objects illuminated by light, evident. The apparatus is a glass bowl filled with water, positioned in-relation-to an expansive view. The images are composed so that the reflective surface of water fills the lower third of the frame. This portion of the image is in focus, and the remainder is softly focused. The images do not visually reference the scene in front of the camera as it appears to the naked eye. What the image shows and what I can see through the viewfinder, is a field of light structured by the relations between proximity and distance. These formal parameters both delimit the field of enquiry and align with the pictorial conventions of landscape representation. As the project progressed, I maintained this reductive approach to composition, working with the landscape convention stripped to bare bones (foreground, background and horizon). I became more and more interested in how spatial qualities are registered somatically at subtle, physical and emotional levels. It is the subtle nuance of these often hidden and unarticulated relations which I am aiming to bring forward in the resulting artworks. This exploration led to a formal analysis of the philosophical concept of aura, drawing upon the writing primarily of Walter Benjamin, Diarmuid Costello, Gunter Figal and Theodor Adorno. I define aura as a relation of intimate distance, between the perceiving subject and the perceptual object. In this project, aura is characterised by fluid, mobile relations and an integrative movement between proximity and distance that does not collapse or undermine that distance. In conclusion, the work amplifies perceptual, structural and aesthetic relations between embodied self and the environing world.
A Geometric Approach for Computing the Kernel of a Polyhedron

description: We present a geometric algorithm to compute the geometric kernel of a generic polyhedron. The geometric kernel (or simply kernel) is defined as the set of points from which the whole polyhedron is visible. Whilst the computation of the kernel for a polygon has already been largely addressed in the literature, less has been done for polyhedra. Currently, the principal implementation of the kernel estimation is based on the solution of a linear programming problem. We compare against it on several examples, showing that our method is more efficient in analysing the elements of a generic tessellation. Details on the technical implementation and discussions on pros and cons of the method are also provided.

The True Durations of Starbursts: HST Observations of Three Nearby Dwarf Starburst Galaxies

description: The duration of a starburst is a fundamental parameter affecting the evolution of galaxies yet, to date, observational constraints on the durations of starbursts are not well established. Here we study the recent star formation histories (SFHs) of three nearby dwarf galaxies to rigorously quantify the duration of their starburst events using a uniform and consistent approach. We find that the bursts range from ~200 - ~400 Myr in duration resolving the tension between the shorter timescales often derived observationally with the longer timescales derived from dynamical arguments. If these three starbursts are typical of starbursts in dwarf galaxies, then the short timescales (3 - 10 Myr) associated with starbursts in previous studies are best understood as "flickering" events which are simply small components of the larger starburst. In this sample of three nearby dwarfs, the bursts are not localized events. All three systems show bursting levels of star formation in regions of both high and low stellar density. The enhanced star formation moves around the galaxy during the bursts and covers a large fraction of the area of the galaxy. These massive, long duration bursts can significantly affect the structure, dynamics, and chemical evolution of the host galaxy and can be the progenitors of "superwinds" that drive much of the recently chemically enriched material from the galaxy into the intergalactic medium.

Reposing and Retargeting Unrigged Characters with Intrinsic-extrinsic Transfer

description: In the 3D digital world, deformations and animations of shapes are fundamental topics for several applications. The entertainment industry, virtual and augmented reality, human-robot interactions are just some examples that pay attention to animation processes and related tools. In these contexts, researchers from several communities desire to govern deformations and animations of 3D geometries. This task is generally very complicated because it requires several skills covering different kinds of knowledge. For this reason, we propose a ready-to-use procedure to transfer a given animation from a source shape to a target shape that shares the same global structure. Our method proposes highly geometrical transferring, reposing, and retargeting, providing high-quality and efficient transfer, as shown in the qualitative evaluation that we report in the experimental section. The animation transfer we provide will potentially impact different scenarios, such as data augmentation for learning-based procedures or virtual avatar generation for orthopedic rehabilitation and social applications.

LengthNet: Length Learning for Planar Euclidean Curves
Creators: name: Or, Barak

Publisher: name: The Eurographics Association
Year: 2021

description: In this work, we used a deep learning (DL) model to solve a fundamental problem in differential geometry. One can find many closed-form expressions for calculating curvature, length, and other geometric properties in the literature. As we know these properties, we are highly motivated to reconstruct them by using DL models. In this framework, our goal is to learn geometric properties from many examples. The simplest geometric object is a curve, and one of the fundamental properties is the length. Therefore, this work focuses on learning the length of planar sampled curves created by a simulation. The fundamental length axioms were reconstructed using a supervised learning approach. Following these axioms, a DL-based model, we named LengthNet, was established. For simplicity, we focus on the planar Euclidean curves.

Dynamical Mean Field Theory for the Bose-Hubbard Model

description: The dynamical mean field theory (DMFT), which is successful in the study of strongly correlated fermions, was recently extended to boson systems [Phys. Rev. B {\textbf 77}, 235106 (2008)]. In this paper, we employ the bosonic DMFT to study the Bose-Hubbard model which describes on-site interacting bosons in a lattice. Using exact diagonalization as the impurity solver, we get the DMFT solutions for the Green's function, the occupation density, as well as the condensate fraction on a Bethe lattice. Various phases are identified: the Mott insulator, the Bose-Einstein condensed (BEC) phase, and the normal phase. At finite temperatures, we obtain the crossover between the Mott-like regime and the normal phase, as well as the BEC-to-normal phase transition. Phase diagrams on the $μ/U-\tilde{t}/U$ plane and on the $T/U-\tilde{t}/U$ plane are produced ($\tilde{t}$ is the scaled hopping amplitude). We compare our results with the previous ones, and discuss the implication of these results to experiments.
