description: We use the mock catalog of galaxies, constructed based on the COSMOS galaxy catalog including information on photometric redshifts (photo-z) and SED types of galaxies, in order to study how to define a galaxy subsample suitable for weak lensing tomography feasible with optical (and NIR) multi-band data. Since most of useful cosmological information arises from the sample variance limited regime for upcoming lensing surveys, a suitable subsample can be obtained by discarding a large fraction of galaxies that have less reliable photo-z estimations. We develop a method to efficiently identify photo-z outliers by monitoring the width of posterior likelihood function of redshift estimation for each galaxies. This clipping method may allow to obtain clean tomographic redshift bins (here three bins considered) that have almost no overlaps between different bins, by discarding more than 70% galaxies of ill-defined photo-z's corresponding to the number densities of remaining galaxies less than 20 per square arcminutes for a Subaru-type deep survey. Restricting the ranges of magnitudes and redshifts and/or adding near infrared data help obtain a cleaner redshift binning. By using the Fisher information matrix formalism, we propagate photo-z errors into biases in the dark energy equation of state parameter w. We found that, by discarding most of ill-defined photo-z galaxies, the bias in w can be reduced to the level comparable to the marginalized statistical error, however, the residual, small systematic bias remains due to asymmetric scatters around the relation between photometric and true redshifts. We also use the mock catalog to estimate the cumulative signal-to-noise (S/N) ratios for measuring the angular cross-correlations of galaxies between finner photo-z bins, finding the higher S/N values for photo-z bins including photo-z outliers.

The Need to Review Low-Dose Decision-Making in Radiation Protection

description: The current approach in the system of protection, and the way in which it is implemented in regulatory practice, has resulted in the allocation of significant and disproportionate societal resources to reduce relatively low level exposures to even lower levels. The resulting exposure levels are often a fraction of the basic natural background level, and in particular are comparable to, or often significantly less than, the variability of natural background exposures due to individual decision-making, which the system of protection deems acceptable. There are arguments for a wider approach to decision-making at such low doses, recognising the uncertainties in radiation risk estimation and acknowledging the context that all human life takes place in a variable natural background radiation which generally dominates these lower dose exposures. Recommendations for such improvement in how decisions are made are presented.

Ecology and conservation of ground-dwelling beetles in managed wet eucalypt forest: edge and riparian effects
Creators: name: Baker, SC
Publisher: name: University Of Tasmania
Year: 2023

description: Limited understanding of the ecology of ground-dwelling invertebrates in Tasmania has hampered our ability to assess the adequacy of forest management. This thesis documents the distributions of ground-dwelling beetle assemblages in managed, wet eucalypt forests of southern Tasmania, and explores the response of beetles to ecological gradients caused by riparian influences near small streams (since retained riparian corridors are a major conservation tool), and edge effects from recently clearfelled logging coupes. Extensive pitfall trapping using replicated transects at four sites was employed to compare the beetle fauna between five habitats: young logging regeneration, the interior of upslope mature forest, the riparian-upslope transition in mature forest interior, and across coupe edges (both into upslope mature forest and into streamside reserves). Data screening ensured that the primary transect design, which employed traps positioned at unequal distances within transects, was unlikely to produce patterning in beetle distributions attributable to spatial autocorrelation or pitfall trap depletion. \ \ Beetles responded to riparian influences, showing subtle shifts in assemblage composition, and generally reduced abundance or species richness nearer to streams. However, site differences outweighed riparian effects. Beetles assemblage composition differed substantially between young logging regeneration and mature forest: several species were identified as indicators of each habitat. Beetles responded more strongly to edge effects than to riparian influences. Depth of edge influence extended ~ 22 m into unlogged non-riparian forest, but further into streamside reserve edges (up to ~ 65 m). Four beetle species, Choleva TFIC sp 01 (Leiodidae), Decilaus nigronotatus, D. lateralis and D. striatus (all Curculionidae), were indicators of mature forest interior. \ \ A second survey compared beetles between logging regeneration, upslope mature forest interior, mature forest interior riparian areas, and streamside reserves that had been logged on both sides, in five stands of each of the four habitats. Streamside reserves (average width 40 +/-6 m (+/- 95% CI) from reserve edge to stream) supported different beetle assemblages to unlogged areas, and were probably entirely edge-effected. \ \ These results suggest that current corridor provisions, which rely heavily on riparian reserves, may be inadequate to conserve beetles dependent on mature forest interior. Reserve corridors may need to be wider, and should more often be positioned upslope away from riparian areas. Alternatively, a mix of different types of reservation strategies (e.g. conserving some contiguous blocks of mature forest in lieu of widened corridors) needs to be developed to increase the probability that edge-sensitive and mature forest specialist taxa will be conserved.

description: Weighted histograms in Monte Carlo simulations are often used for the estimation of probability density functions. They are obtained as a result of random experiments with random events that have weights. In this paper, the bin contents of a weighted histogram are considered as a sum of random variables with a random number of terms. Generalizations of the classical chi-square test for comparing weighted histograms was proposed. Numerical examples illustrate an application of the tests for the histograms with different statistics of events and different weighted functions. The proposed tests can be used for the comparison of experimental data histograms with simulated data histograms, as well as for the two simulated data histograms.

description: We consider the renormalization of general gauge theories on curved space-time background, with the main assumption being the existence of a gauge-invariant and diffeomorphism invariant regularization. Using the Batalin-Vilkovisky (BV) formalism one can show that the theory possesses gauge invariant and diffeomorphism invariant renormalizability at quantum level, up to an arbitrary order of the loop expansion. Starting from this point we discuss the locality of the counterterms and the general prescription for constructing the power-counting renormalizable theories on curved background.

The strategies of waiting : a study of action in Samuel Beckett's plays
Creators: name: White, Richard Kerry
Publisher: name: University of British Columbia
Year: 2011

description: This essay is principally concerned with the nature and possibilities of action in Samuel Beckett1s four major stage plays: Waiting for Godot, Endgame, Krapp's Last Tape, and Happy Bays. The problem arises from the fact that each of these plays is organically inconclusive, indicating that the action is not causally structured in the Aristotelean sense. Action is therefore examined in terms of the characters' separate activities: how they are initiated and terminated, their internal order, and their relation to each play as a whole. The three basic sources employed for criteria are Beckett's critical essay, Proust; his early novels, Murphy and Watt; and Johan Huizinga's Homo Ludens. Proust provides a clear indication of Beckett's theories on time, habit, and friendship; Murphy and Watt are seen as character prototypes; and Homo Ludens is useful in that it supplies a working definition of play. After a detailed examination of each play in the above terms, the general conclusion reached is that in all cases Beckett has portrayed a state of being as opposed to a process of becoming. In other words, the characters feel and act as though they are caught in an endless present: in their situations they feel cut off from their past, and at the same time they cannot plan and project their activities toward a known goal, for the future is completely uncertain. Consequently, aside from those moments when the characters have no effective control over their actions, and aside from those actions governed by some form of necessity, everything they do during the course of the plays is done simply to fill the enormous void of time. Considered separately, each activity or strategy of waiting is seen to conform to the characteristics of play as defined by Huizinga, and furthermore, each activity is seen as a habitual response to reality. The similarities between one activity and another are conditioned by two fundamental factors: a subject-object dichotomy, or the relation between the individual, the world, and other people; and death, the one event in human life which is certain, but not fixed. The differences between the various activities, on the other hand, are conditioned primarily by the ages of the characters: the older a character is the more he loses contact with the world and other people, and this affects the scope of his activities. It is finally concluded that Beckett has portrayed the fundamental isolation of western man—the tragicomedy of individualism. Cut off from others and time, man's habitual response to life and the external world has been to devise strategies of waiting for the time when it will all end.
Nesting habitat preferences of snow petrels (Pagodroma nivea) and Wilson's storm petrels (Oceanites oceanicus) in East Antarctica : a modelling approach to predict species distribution
Creators: name: Olivier, F
Publisher: name: University Of Tasmania
Year: 2023

description: Although snow petrels are ubiquitous around the Antarctic, population estimates of this not so charismatic‚ÄövÑvp top predator are generally limited. Such information is highly valuable for the monitoring and management of Antarctic and Southern Ocean ecosystems, especially in a climate change context. There is a need to complement long‚Äö-term temporal demographic information obtained at a limited number of monitoring sites with spatial distribution data. Systematic surveys of snow petrels and Wilson's storm petrels were undertaken at Casey (2002-2003) and Mawson (2004-2005) in order to provide better regional population estimates and test the performance of predictive distribution models based on topographic and substrate variables for refining such estimates. As habitat selection modelling is rarely used in Antarctic regions, methodological developments focus on dealing with the peculiarities of a semi-colonial hollow-nesting species, testing habitat selection modelling approaches and comparing the output of four types of models (Generalized Linear and Generalized Additive Models, Classification Trees and Ecological Niche Factor Analysis) across a range of scales. Snow petrel nest distribution was directly related to the nature of the rock substrate and to major topographic/geomorphological parameters such as hill slope and the direction of the prevailing winds. Model performance varied with the scale at which models were implemented, suggesting that nest selection processes happen predominantly at the habitat unit and individual nest scales. Further study at the nest scale highlighted that the influence of biotic related parameters such as conspecific attraction (modelled as autocorrelation due to coloniality) may be of lesser influence than selection based on individual nest quality. An alternative modelling method, ENFA, which creates environmental envelopes for the niche of the species with presence data only was identified as valuable for Antarctic data sets, which often lack comprehensive records of species absence. The validation of the models created at Casey with nest data collected in the Mawson region returned satisfactory prediction rates in two different habitat types, coastal islands and inland mountains, suggesting that it may be possible to predict snow petrel distribution across East Antarctica using remotely sensed information on topography and geomorphology, for example high-resolution aerial photography to guide in the design of and complement ground surveys. Similar modelling procedures applied to Wilson's storm petrels produced more mitigated results and selection for this species appeared to be based principally on nest microhabitat characteristics. However, modelling provided useful information on the large-scale habitat preferences and ecological requirements of both species.

description: We investigate the level population statistics and degree of coherence encoded in the single-particle density matrix of harmonically trapped low-dimensional [quasi-one-dimensional (quasi-1D) or quasi-two-dimensional (quasi-2D)] Bose gases with repulsive contact interactions. Using a variational analysis, we derive fragmentation of the condensate in the weakly confining directions into two (quasi-1D) respectively three (quasi-2D) mutually incoherent macroscopic pieces, upon increasing a dimensionless interaction measure beyond a critical value. Fragmented condensate many-body states in low-dimensional systems therefore occur well before the thermodynamic limit of infinite extension is reached, in which phase fluctuations of the matter wave field create an infinite number of nonmacroscopic fragments.

Collinear antiferromagnetic state in a two-dimensional Hubbard model at half filling

Year: 2010
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: In a half-filled Hubbard model on a square lattice, the next-nearest-neighbor hopping causes spin frustration, and the collinear antiferromagnetic (CAF) state appears as the ground state with suitable parameters. We find that there is a metal-insulator transition in the CAF state at a critical on-site repulsion. When the repulsion is small, the CAF state is metallic, and a van Hove singularity can be close to the Fermi surface, resulting in either a kink or a discontinuity in the magnetic moment. When the on-site repulsion is large, the CAF state is a Mott insulator. A first-order transition from the CAF phase to the antiferromagnetic phase and a second-order phase transition from the CAF phase to the paramagnetic phase are obtained in the phase diagram at zero temperature.

Graded Approach
Planned Exposure situation
Reasonableness
Holistic approach

description: The concept of the “graded approach” has become an essential part of the modern radiation protection. It has been introduced in recent ICRP publications (ex. Publications 122, 126, 132 and 142) for different exposure situations, but with various definitions. Another definition has been proposed later in the ICRPpedia. In Europe, the graded approach has been transposed in the national laws from the Article 24 of the Euratom Directive 2013/59. In this context, the European ALARA Network (EAN) and the European Radiation Protection Authority Network (ERPAN) has set up in 2018 a brainstorming meeting to discuss the interpretation and the practical implementation of the graded approach for workers at workplace. After the meeting, the participants decided to launch a survey addressed to regulators and professionals via the EAN and ERPAN networks to collect more examples and additional points of view. The objective of this contribution is to provide a synthesis of the analysis of the 20 cases study collected (in the medical field, existing exposure situations, etc.) and to bring to the light several topics about the implementation of the graded approach and notably those that could find echo in recent and current ICRP’s reflections, inter alia: - No two similar graded approaches were collected, confirming that there is no harmonized procedure and the graded approach is currently shaped on case-by-case, fully depending on the sector and the circumstances. Despite the differences, a global scheme coming from the analysis of the cases study will be presented, a plausible basis for an harmonized graded approach. In addition, several good practices to ensure that the graded approach is comprehendible and functional will be presented. - The benefits of the graded approach for radiation protection and notably its interest for achieving the reasonableness in the protection, e.g. in ensuring a better allocation of resources. - The potential pitfalls when applying the graded approach and the specific issues to be aware of, including ethical ones. - Several examples are showing that non-radiological criteria should be considered for the graduation, and can even dominate the decision, making the graded approach not necessarily “proportionate”. Moreover, by replacing the radiation protection in a global context, the graded approach is a concrete attempt to make use of the ‘holistic approach’.

description: Global mantle discontinuities and mantle transition zones are crucial to the earth’s evolution. By employing K-Means clustering, which belongs to cluster analysis in machine learning (ML), on shear velocity variation data, we generate heterogeneity percentage profiles for three different global tomographic models (Models S362WMANI+M, SEMUCB-WM1, and S40RTS). Key cluster percentage shifts, which are observed at around 400 km, 650 km, 1050 km, 1500 km, and 2700 km, suggest global mantle discontinuities at corresponding depths. All profiles also indicate a global discontinuity in the lower mantle between 2200 km and 2600 km. The middle mantle transition zone (MMTZ), bounded between 1050 km and 1500 km discontinuities, is detected for the first time. Mantle convection modeling with the global geoid is conducted using the HC code to demonstrate the viscosity jump in this new MMTZ.

Timon of Athens : its relationship to other plays of the Shakespeare canon. A study of the play with special reference to themes related to Judaic-Christian thought and expressed through the plot, characterization and imagery of the drama
Creators: name: Webber, Jean P.
Publisher: name: University of British Columbia
Year: 2011

description: Timon of Athens has been the subject of conflicting interpretations and evaluations. Those who have found it somewhat unsatisfactory have outnumbered those who have approved it. To explain its more troubling features critics have advanced two theories: first, that the play is written by Shakespeare in collaboration with another author; and second, that the play is all Shakespeare's but lacks final revision. This thesis reviews the critical history of the play, supporting the current general tendency to reject the theory of dual authorship and seeing design in the form of the play and consistency in the development of character and plot. The writer investigates the themes presented in the play, noting relationships to themes in other plays of the canon. The marked similarities in ideas, imagery, and diction between Timon of Athens and other Shakespearian dramas supports the view of those who regard the play as entirely Shakespeare's. In particular, the treatment given the themes of justice, mercy, grace, and regeneration and the manner in which death is shown to affect character demonstrates that the play is a link between the tragedies and the final tragi-comedies. The writer believes that the play is satisfactory and understandable if it is regarded as depicting the movement of the soul from the finite to the infinite conception of being. Timon is accordingly viewed as a type of Everyman. Biblical imagery and echoes are noted, particularly those lines recalling passages (in both the Old and New Testaments) dealing with atonement. The principal characters of the play, other than the soldier Alcibiades and the faithful steward, exemplify various phases of worldliness and material-mindedness. Alcibiades stands in a special relationship to Timon in that he remains loyal to him, punishes Timon’s enemies, purges the state, and finally restores order. However, Alcibiades is not above criticism for his actions involve the evils of civil war and disease. The steward, also, remains loyal to Timon. Through his pure love he is able to touch Timon and thus penetrate his misanthropy. As Timon grows towards death there are hints of his moving into a state in which sin is absolved and all faults forgiven. Some attention has been given to the stage history of Timon of Athens, in particular to the 1965 Royal Shakespeare Company production which proved theatrically successful. The treatment of themes similar to those of Timon in other plays is discussed from a theatrical point of view in an attempt to explain the greater popularity with theatre audiences of plays such as King Lear.

We show that $\mathcal{N}=1$ MHV super-vertices can be described by a formula similar to that of the $\mathcal{N}=4$ MHV super-amplitude. In the discussions we briefly remark on how to derive Nair's formula for $\mathcal{N}=4$ SYM theory directly from light-cone lagrangian.

description: We calculate how strongly one can constrain the alternative theories of gravity with deci-Hz gravitational wave interferometers such as DECIGO and BBO. Here we discuss Brans-Dicke theory and massive graviton theories as typical examples. We consider the inspiral of compact binaries composed of a neutron star (NS) and an intermediate mass black hole (IMBH) for Brans-Dicke (BD) theory and those composed of a super massive black hole (SMBH) and a black hole (SMBH) for massive graviton theories. Using the restricted 2PN waveforms including spin effects and taking the spin precession into account, we perform the Monte Carlo simulations of $10^4$ binaries to estimate the determination accuracy of binary parameters including the Brans-Dicke parameter $ω_{\mathrm{BD}}$ and the graviton Compton length $λ_g$. Assuming a $(1.4, 10)M_{\odot}$ NS/BH binary of SNR=$\sqrt{200}$, the constraint on $ω_{\mathrm{BD}}$ is obtained as $ω_{\mathrm{BD}}>2.32\times 10^6$, which is 300 times stronger than the estimated constraint from LISA observation. Furthermore, we find that, due to the expected large merger rate of NS/BH binaries of $O(10^4)$ yr$^{-1}$, a statistical analysis yields $ω_{\mathrm{BD}}>3.77\times10^8$, which is 4 orders of magnitude stronger than the current strongest bound obtained from the solar system experiment. For massive graviton theories, assuming a $(10^6, 10^5)M_{\odot}$ BH/BH binary at 3Gpc, one can put a constraint $λ_g>3.35\times10^{20}$cm, on average. This is three orders of magnitude stronger than the one obtained from the solar system experiment. From these results, it is understood that DECIGO/BBO is a very powerful tool for constraining alternative theories of gravity, too.

description: We consider a dense n-user Gaussian interference network formed by paired transmitters and receivers placed independently at random in Euclidean space. Under natural conditions on the node position distributions and signal attenuation, we prove convergence in probability of the average per-user capacity C_Sigma/n to 1/2 E log(1 + 2SNR). The achievability result follows directly from results based on an interference alignment scheme presented in recent work of Nazer et al. Our main contribution comes through the converse result, motivated by ideas of `bottleneck links' developed in recent work of Jafar. An information theoretic argument gives a capacity bound on such bottleneck links, and probabilistic counting arguments show there are sufficiently many such links to tightly bound the sum-capacity of the whole network.

description: We study a pure gluon plasma in the context of quasiparticle models, where the plasma is considered as an ideal gas of massive bosons. In order to reproduce SU(3) gauge field lattice data within such a framework, we review briefly the necessity to use a temperature-dependent gluon mass which accounts for color interactions between the gluons near $T_{\text{c}}$ and agrees with perturbative QCD at large temperatures. Consequently, we discuss the thermodynamics of systems with temperature-dependent Hamiltonians and clarify the situation about the possible solutions proposed in the literature to treat consistently those systems. We then focus our attention to two possible formulations which are thermodynamically consistent and we extract the gluon mass from the equation of state obtained in SU(3) lattice QCD. We find that the thermal gluon mass is similar in both statistical formalisms. Finally, an interpretation of the gluon plasma as an ideal gas made of glueballs and gluons is also presented. The glueball mass is consistently computed within a relativistic formalism using a potential obtained from lattice QCD. We find that the gluon plasma might be a glueball-rich medium for $T\lesssim 1.13 T_{\text{c}}$ and suggest that glueballs could be detected in future experiments dedicated to the quark-gluon plasma.

The metabolic signature of small headwater streams: Natural variability and the response to forestry
Creators: name: Clapcott, JE
Publisher: name: University Of Tasmania
Year: 2023

description: A strong connection to the landscape means that small headwater stream metabolism is easily disturbed by land management practices such as forestry. A current landscape ecology framework, the hierarchical patch dynamics paradigm, was applied to examine the heterogeneity of small headwater stream metabolism and how it is affected by anthropogenic disturbance. Metabolism was examined at several scales to elucidate specific metabolic components and processes, including microbial community structure, bacterial carbon productivity, cellulose decomposition potential, algal accumulation, and ecosystem respiration and productivity. Firstly, in-stream metabolic patch dynamics was examined throughout a calendar year. Small headwater streams displayed very low metabolic rates dominated by heterotrophic processes. Predictable spatial and temporal patterns in population-level, community-level, and whole system-level metabolisms were observed, shaped by temperature, hydrology, and the physical and chemical properties of patches. Secondly, an inundation experiment was conducted to examine metabolic patch dynamics in a small headwater landscape. Inundation resulted in increased metabolic response and a change in the metabolic community profile of the terrestrial patch. It is suggested that regular, above-bank flows are likely to transfer the complexities of in-stream patch dynamics into the terrestrial environment, exemplifying the strong connection between headwater streams and the surrounding landscape. Thirdly, the impact of forestry on stream metabolism was examined by a survey of small headwater streams 2-5 years after logging. Forestry stimulated autotrophy and lead to increased metabolic rates. Methods that incorporate temporal variability, such as cellulose decomposition potential, provided a strong assessment of forestry impact and are recommended as robust indicators of disturbance. Fourthly, the potential recovery of stream metabolism from the impacts of forestry was examined by a survey of small headwater streams 2-15 years after logging. Only autotrophic processes displayed recovery over time, with a sustained change in heterotrophic form and function. It is suggested that, together, these surveys demonstrate a lack of resistance and resilience to forestry disturbance in the key metabolic processes of small headwater streams. Finally, through the description of metabolic patterns a metabolic 'signature' of small headwater streams is presented. The metabolic signature provides a characterisation of small headwater stream metabolism and contributes to our understanding of small headwater stream ecology.

description: A scaling law analysis of the world data on inclusive large-pT hadron production in hadronic collisions is carried out. A significant deviation from leading-twist perturbative QCD predictions at next-to-leading order is reported. The observed discrepancy is largest at high values of xT=2pT/sqrt(s). In contrast, the production of prompt photons and jets exhibits the scaling behavior which is close to the conformal limit, in agreement with the leading-twist expectation. These results bring evidence for a non-negligible contribution of higher-twist processes in large-pT hadron production in hadronic collisions, where the hadron is produced directly in the hard subprocess rather than by gluon or quark jet fragmentation. Predictions for scaling exponents at RHIC and LHC are given, and it is suggested to trigger the isolated large-pT hadron production to enhance higher-twist processes.

description: The prospects for the analysis of tau channels at the SUSY benchmark point SPS1a', especially from e+e- -> stau_1 stau_1 and e+e- -> stau_2 stau_2, have been studied in full simulation of the ILD detector concept forseen for the International Linear Collider. All accessible SUSY channels as well as all Standard Model backgrounds were generated at a centre-of-mass energy E_CMS=500 GeV, including the beam energy spectrum and beam backgrounds expected for nominal ILC beam parameters. With an integrated luminosity of 500 fb-1 delivered to the experiment, the masses of the stau_1 and stau_2 can be measured to 107.69^{+0.03}_{-0.06} GeV +- 1.1 δM_LSP and 183 ^{+11}_{-5} GeV +- 18 δM_LSP, respectively, while the true values in SPS1a' are 107.9 GeV and 194.9 GeV, respectively. The cross sections for stau_1 and stau_2 pair production could be obtained with a precision of 3.1% and 4.2%, respectively. Combining the mass and cross section measurement in the stau_2 channel allows to determine the LSP mass with a relative error of 1.7%, assuming a known mixing angle. In stau_1 -> tau LSP decays, the tau polarisation is measured to be 91 +- 9% and 87.0 +- 3.4% in the pi and rho decay channels of the tau, respectively. The true value in the simulated SPS1a' sample is 89.6%.

description: This work has been done as a part of scientific deliverable 4.1 of ITN Rainbow.(https://rainbow.ku.dk). A. In first part program is written for predicting the position of brain tumour in brain surgery. In the surgery, as surgeonmakes incision and opens the skull, the brain tumour relocates under new boundary conditions. Predicting the position of tumor under different incision sizes is invaluable data for surgeons, which is done by using gaussian process regressor meta-model. B. Second part shows the potential of deep learning approach to solve non-linear deformation behaviour of a cantilever beam in real time constraints. It is shown that deep learning model is able to predict the solution in a very less time compared to finite element solution time and yet maintaining the reasonable accuracy.
It Is Difference Which Signifies: The Visual Design of Collective Representations

description: One of the most ancient philosophical problems is represented by the tension between the individual and the collective. Sometimes two elements are similar because of their estrangement from the context, sometimes the same two elements are different because of the homogeneity of the other elements. Today’s algorithms of artificial intelligence help us to compute the similarity between elements of different types, from documents to images. This presentation is about the last three years of research conducted during my stay at the Massachusetts Institute of Technology and Harvard University. In such a period my interest focused on the way in which a large number of elements can be presented in the form of network visualization and how the distance between them can be computed. The examples you will see concern mainly digital archives of texts and images. Among them two projects are valuable to be mentioned, the 3D Cartography of Covid-19, representing more than half a million scientific articles on the current pandemic, and Surprise Machines, a digital installation for the Harvard Art Museums in which more than 200,000 images are displayed simultaneously.

description: We consider the Renyi alpha-entropies for Luttinger liquids (LL). For large block lengths l these are known to grow like ln l. We show that there are subleading terms that oscillate with frequency 2k_F (the Fermi wave number of the LL) and exhibit a universal power-law decay with l. The new critical exponent is equal to K/(2 alpha), where K is the LL parameter. We present numerical results for the anisotropic XXZ model and the full analytic solution for the free fermion (XX) point.

description: Numerical renormalization group (NRG) calculations of quantum impurity models, based on a logarithmic discretization in energy of electronic or bosonic Hamiltonians, provide a powerful tool to describe physics involving widely separated energy scales, as typically encountered in nanostructures and strongly correlated materials. This main advantage of the NRG was however considered a drawback for resolving sharp spectral features at finite energy, such as dissipative atomic peaks. Surprisingly, we find a bunching of many-body levels in NRG spectra near dissipative resonances, and exploit this by combining the widely-used Oliveira's $z$-trick, using an averaging over {\it few} discrete NRG spectra, with an optimized {\it frequency-dependent} broadening parameter $b(\w)$. This strategy offers a tremendous gain in computational power and extracts all the needed information from the raw NRG data without {\it a priori} knowledge of the various energy scales at play. As an application we investigate with high precision the crossover from coherent to incoherent dynamics in the spin boson model.

description: We investigate Higgs boson production process via gluon fusion at LHC in our six dimensional universal extra dimension model compactified on a spherical orbifold S^2/Z_2. We find a striking result that Higgs production cross section in our model is predicted to be 30(10)% enhancement comparing to the predictions of the Standard Model (the minimal universal extra dimension model) for the compactification scale of order 1 TeV.

Living Above the Dead: A History of the Redevelopment of Six Launceston Urban Burial Places, 1931-1963
Creators: name: Mallett, RA
Publisher: name: University Of Tasmania
Year: 2023

description: Living Above the Dead, is an historical analysis of the redevelopment of the intramural burial places of Launceston, Tasmania, Australia, between 1931 an 1963. The thesis draws on the multitude of historiography that has emerged over recent decades, addressing the changing cultural beliefs and practices relating to the disposal of the dead. The thesis attempts to explain the process by which, and the reasons why, the burial places within the city were so drastically erased during the stated period. There is a discussion of global trends relating to topic and similar activity in London, Sydney and Hobart. The manner in which the meaning, purpose and practicality of burial places altered over time is outlined by virtue of detailing the individual histories of the development of the six intramural burial grounds of Launceston. This is followed by a discussion of how cultural attitudes to death and burial places in general changed in Launceston and how they echoed wider global trends. Another chapter details how the redevelopments were executed, relating the methods and the motivation back to the aforementioned cultural trends. Considerable photographic material is provided using a comparative method in order to emphasize the cultural loss the redevelopment inflicted on the city over a short, thirty year period. Essentially the thesis is a modest attempt to move the debate on cultural attitudes and beliefs related to death and burial forward within an Australian context by using the city of Launceston as a case study.
