description: We study the effect of an optical lattice (OL) on the ground-state properties of one-dimensional ultracold bosons with three-body attraction and two-body repulsion, which are described by a cubic-quintic Gross-Pitaevskii equation with a periodic potential. Without the OL and with a vanishing two-body interaction term, soliton solutions of the Townes type are possible only at a critical value of the three-body interaction strength, at which an infinite degeneracy of the ground-state occurs; a repulsive two-body interaction makes such localized solutions unstable. We show that the OL opens a stability window around the critical point when the strength of the periodic potential is above a critical threshold. We also consider the effect of an external parabolic trap, studying how the stability of the solitons depends on matching between minima of the periodic potential and the minimum of the parabolic trap.

description: This work presents, to our knowledge, the first completely passive imaging with human-body-emitted radiation in the lower THz frequency range using a broadband uncooled detector. The sensor consists of a Si CMOS field-effect transistor with an integrated log-spiral THz antenna. This THz sensor was measured to exhibit a rather flat responsivity over the 0.1–1.5-THz frequency range, with values√ of the optical responsivity and noise-equivalent power of around 40 mA/W and 42 pW/ Hz, respectively. These values are in good agreement with simulations which suggest an even broader flat responsivity range exceeding 2.0 THz. The successful imaging demonstrates the impressive thermal sensitivity which can be achieved with such a sensor. Recording of a 2.3 × 7.5-cm2-sized image of the fingers of a hand with a pixel size of 1 mm2 at a scanning speed of 1 mm/s leads to a signal-to-noise ratio of 2 and a noise-equivalent temperature difference of 4.4 K. This approach shows a new sensing approach with field-effect transistors as THz detectors which are usually used for active THz detection. © 2020 by the authors. Licensee MDPI, Basel, Switzerland.
title: Meal Duration: Implications for Restaurant Revenue Management
Creators: name: Billings, Dale F.
Publisher: name: University of Nevada, Las Vegas
Year: 2019

description: A comprehensive revenue management strategy addressing space, product, price and time, has been shown to increase profits within the hospitality sector. While the literature shows that the restaurant industry has frequently addressed space, product, and price when looking at financial strategy, the effect of the variable of time on revenue generation has not been adequately studied. Restaurants shy away from the practice of using time as a commodity, particularly regarding meal duration, due to fears of reducing customer satisfaction.
This project explores the use of time as a commodity in restaurant revenue management. In particular, it examines consumers’ feelings about meal duration and their willingness to accept parameters around time spent at the table. This project shows that consumers have neutral to positive feelings about a fixed meal duration. Triangulating the existing research with this project’s findings, a 60-minute fixed meal duration could be a viable, financially-sound strategy for restaurant revenue management.

Energy, air and climate change: a new sculptural language
Creators: name: Singe, MN
Publisher: name: University Of Tasmania
Year: 2023

description: This project has developed a sculptural language that actively responds to and participates in the climate change debate. It employs energy and air as key materials in direct response to climate change, a discourse framed and driven by the relationship between energy use and the earth's atmosphere. The research was motivated by a desire to develop an alternative approach to making environmentally engaged sculpture where singular strategies, such as utilising only recycled materials, have limitations in their ability to address the complex and seemingly intangible nature of climate change. While the project has historical links to environmental and land art that emerged in the 1960s, the contextual focus has been sustainable design, sculpture and installation art which strategically integrate the materials of energy and air, made since the 1980s, the period in which the world became more aware about global warming. By synthesising formal and conceptual approaches from these sources, the project has developed a multifaceted sculptural language in response to the complexity of climate change. This language has been informed by artists such as Simon Starling and Tue Greenfort who create installation-based environmental systems. The metaphorical link between global warming and human respiration emphasized by Maria Miranda and Norie Neumark in their work Talking About the Weather (2006 ongoing) has been substantially explored in this project. The research output consists primarily of sculptural objects whose form and function have been inspired by sustainable design and DIY culture. These objects require physical human input to demonstrate the mechanical dimension of their relationship to climate change. The sculptures are supplemented by video documentation that depicts their activation in order to parody emergent climate change solutions such as alternative energy generation and carbon capture and storage. My presence in these videos as a test subject or tragic anti-hero offers a blackly humorous critique of individual climate change convictions. Singular strategies for creating environmentally engaged sculpture are limited in their ability to respond to climate change. Through the strategic use of energy and air in a series of sculptural objects that incorporate elements of sustainable design and DIY culture, this research has developed a multifaceted language that actively responds to this complex environmental issue. By parodying alternative energy generation systems and highlighting a metaphorical association between global warming and human respiration, the project creates an opportunity for the viewer to reassess their climate change beliefs.

description: A dual conformal symmetry, analogous to the dual conformal symmetry observed for the scattering amplitudes of N=4 Super Yang-Mills theory, is identified in the Regge limit of QCD. Combined with the original two-dimensional conformal symmetry of the theory, this dual symmetry can potentially explain the integrability of the BFKL Hamiltonian. We also give evidence that the symmetry survives when a subset of unitarity corrections are taken into account by studying briefly the non-planar 2 to m reggeon transition vertices.

description: Super-resolved structured illumination microscopy (SR-SIM) is among the fastest fluorescence microscopy techniques capable of surpassing the optical diffraction limit. Current custom-build instruments are able to deliver two-fold resolution enhancement with high acquisition speed. SR-SIM is usually a two-step process, with raw-data acquisition and subsequent, time-consuming post-processing for image reconstruction. In contrast, wide-field and (multi-spot) confocal techniques produce high-resolution images instantly. Such immediacy is also possible with SR-SIM, by tight integration of a video-rate capable SIM with fast reconstruction software. Here we present instant SR-SIM by VIGOR (Video-rate Immediate GPU-accelerated Open-Source Reconstruction). We demonstrate multi-color SR-SIM at video frame-rates, with less than 250 ms delay between measurement and reconstructed image display. This is achieved by modifying and extending high-speed SR-SIM image acquisition with a new, GPU-enhanced, network-enabled image-reconstruction software. We demonstrate high-speed surveying of biological samples in multiple colors and live imaging of moving mitochondria as an example of intracellular dynamics.

description: We introduce a quantum generalization of classical kinetic Ising models, described by a certain class of quantum many body master equations. Similarly to kinetic Ising models with detailed balance that are equivalent to certain Hamiltonian systems, our models reduce to a set of Hamiltonian systems determining the dynamics of the elements of the many body density matrix. The ground states of these Hamiltonians are well described by matrix product, or pair entangled projected states. We discuss critical properties of such Hamiltonians, as well as entanglement properties of their low energy states.

Is Laplacian determinism compatible with reasons-based freedom?
Creators: name: Sauvage, GC
Publisher: name: University Of Tasmania
Year: 2023

description: The topic of free will is perhaps the largest and richest debate in philosophy. With many notable philosophers having lent their hand to the discussion over the years, there is much that can be said of, and read into, this debate. It is, therefore, essential when engaging in any discussion of free will to make one's analysis well defined and sufficiently narrow in scope. For this reason, this thesis will tackle a specific question in relation to several of the main pillars of free will: compatibilism and determinism. Specifically, I will seek to answer whether Laplacian Determinism (a popular form of determinism) is compatible with reasonsbased freedom (a generalised compatibilist freedom that bases free will on the ability to act for reasons). Is every thesis of compatiblist freewill consistent with every thesis of determinism? I will argue, that at least in this case, the answer to that question is no.

The relevance of variable $Λ$ with regard to various key issues like dark matter, dark energy, geometry of the field, age of the Universe, deceleration parameter and barotropic equation of state has been trivially addressed. The deceleration parameter and the barotropic equation of state parameter obey a straight line relationship for a flat Universe described by Friedmann and Raychaudhuri equations. Both the parameters are found identical for $α= 1$.

description: We present a quantum algorithm to prepare the thermal Gibbs state of interacting quantum systems. This algorithm sets a universal upper bound D^alpha on the thermalization time of a quantum system, where D is the system's Hilbert space dimension and alpha < 1/2 is proportional to the Helmholtz free energy density of the system. We also derive an algorithm to evaluate the partition function of a quantum system in a time proportional to the system's thermalization time and inversely proportional to the targeted accuracy squared.
Non-linear unsteady wave loads on large high-speed wave piercing catamarans
Creators: name: Amin, W
Publisher: name: University Of Tasmania
Year: 2023

description: The current work investigates the slamming characteristics of wave piercing catamarans through the analysis of sea trials data of the 98 m Incat sea frame Hull 061‚ÄövÑvp, built in Tasmania, Australia and currently serving in the US Navy combat fleet. The importance of this sea trials data is that the ship was tested in severe sea conditions to assess her suitability for military operations and to define her operational envelope. New signal processing techniques such as Wavelet Transforms are used in analysing slamming data for two main purposes, slamming identification and modal analysis in time and frequency domains simultaneously. The Wavelet Transforms were found superior to conventional signal processing tools such as Fast Fourier Transform and Short Time Fourier Transform. The structural strength of wave piercing catamarans is studied by introducing a novel sea trials analysis for structural performance assessment in an attempt to simulate real loading conditions. The methodology was tested on normal linear wave loading (without slamming) and was found satisfactory. A Reverse Engineering‚ÄövÑvp approach is introduced to predict slamming loads during sea trials by using the capabilities of Finite Element Analysis using the well known software PATRAN/NASTRAN1. To increase the efficiency of this approach, the load parameters, spatial location and distribution, were investigated through model tests of a similar but larger 112 m Incat hydro-elastic model in the Australian Maritime College towing tank facility. Based on pressure measurements, proper slam load models can be more accurately and efficiently introduced in the finite element analysis. Quasi-static analysis was first performed to examine its suitability to analyse such fast time varying loads. Difficulties in comparison procedures between numerical simulations and trials data have strongly highlighted the need for dynamic analysis. Direct transient dynamic analysis was performed using the dynamic solver of the same software package. Good agreement with trials data was found. The suggested procedure and slamming loading patterns used in the numerical simulation is then verified and can be regarded as a solid base for verification of other theoretical design models.

description: Cardiovascular diseases have been the leading cause of death in modern society. Using vascular stents to treat these coronary and peripheral artery diseases has been one of the most effective and rapidly adopted medical interventions. During the twenty-five years' development of vascular stents, revolutionary cardiovascular stents like drug eluting stents and endothelial progenitor cells capture stents have emerged. In this review, the evolution of vascular stents is summarized, aiming to provide a glimpse into the future of vascular stents. Advanced designs, focusing on the investigations of new substrates, new platforms, new drugs and new biomolecules are currently under evaluation with promising clinical studies. The concept of "time sequence functional stent" has been raised in this paper. It presents anti-proliferative properties in the first phase after implantation and subsequently support endothelialization. It also shows long-term inertness without release of toxic ions or toxic degradation products. The success of this concept is briefly presented with a clinical study in this model stents.

description: We present a novel approach for computing the surface roughness-limited thermal conductivity of silicon nanowires with diameter D < 100 nm. A frequency-dependent phonon scattering rate is computed from perturbation theory and related to a description of the surface through the root-mean-square roughness height Delta and autocovariance length L. Using a full-phonon dispersion relation, we find a quadratic dependence of thermal conductivity on diameter and roughness as (D/Δ)^2. Computed results show excellent agreement with experimental data for a wide diameter and temperature range (25-350 K), and successfully predict the extraordinarily low thermal conductivity of 2 W.m^{-1}.K^{-1} at room temperature in rough-etched 50 nm silicon nanowires.

description: The mass function of super-massive black holes in our cosmic neighborhood is required to understand the statistics of their activity and consequently the origin of the ultra high energy particles. We determine a mass function of black hole candidates from the entire sky except for the Galactic plane. Using the 2MASS catalogue as a starting point, and the well established correlation between black hole mass and the bulge of old population of stars, we derive a list of nearby black hole candidates within the redshift range z < 0.025, then do a further selection based on the Hubble-type, and give this as a catalogue elsewhere. The final list of black hole candidates above a mass of M_BH > 3*10^{6} M_sol has 5,829 entries; moreover doing a further Hubble type correction to account for the selection effects cuts down the number to 2,919 black hole candidates. We also correct for volume, so that this mass function is a volume limited distribution to redshift 0.025 The differential mass function of nearby black hole candidates is a curved function, with a straight simple power-law of index -3 above 10^{8} M_sol, growing progressively flatter towards lower masses, turning off towards a gap below 3*10^{6} M_sol, and then extending into the range where nuclear star clusters replace black holes. The shape of this mass function can be explained in a simple merger picture. Integrating this mass function over the redshift range, from which it has been derived, gives a total number of black holes with z < 0.025, and M_BH > 10^{7} M_sol of about 2.4*10^{4}, or, if we just average uniformly, 0.6 for every square degree on the sky. In different models many of these are candidates for ultra high energy particles sources. If a very small fraction of the super-massive black holes produces ultra high energy cosmic rays, this should be enough to observe the highly inhomogeneous distribution of the galaxies.

description: Upcoming gravitational wave (GW) detectors might detect a stochastic background of GWs potentially arising from many possible sources, including bubble collisions from a strongly first-order electroweak phase transition. We investigate whether it is possible to connect, via a semi-analytical approximation to the tunneling rate of scalar fields with quartic potentials, the GW signal through detonations with the parameters entering the potential that drives the electroweak phase transition. To this end, we consider a finite temperature effective potential similar in form to the Higgs potential in the Standard Model (SM). In the context of a semi-analytic approximation to the three dimensional Euclidean action, we derive a general approximate form for the tunneling temperature and the relevant GW parameters. We explore the GW signal across the parameter space describing the potential which drives the phase transition. We comment on the potential detectability of a GW signal with future experiments, and physical relevance of the associated potential parameters in the context of theories which have effective potentials similar in form to that of the SM. In particular we consider singlet, triplet, higher dimensional operators, and top-flavor extensions to the Higgs sector of the SM. We find that the addition of a temperature independent cubic term in the potential, arising from a gauge singlet for instance, can greatly enhance the GW power. The other parameters have milder, but potentially noticeable, effects.

Integral equation theory applied to polar molecular fluids
Creators: name: Fraser, KJ
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis is an examination of the application of integral equation theory to the study of polar molecular liquids. The integral equation used as the basis for this work is the site-site OrnsteinZernike (SSOZ) equation coupled with the hypernetted chain (HNC) approximation as the closure. The numerical solution of the SSOZ equation using Gillan's method is examined in detail, and in particular for liquid systems with Coulombic interactions. A method is presented for the symmetry reduction of the Jacobian matrix to facilitate the numerical solution for larger molecular systems. This method is not based on the individual analytic reduction of the matrix integral equation for molecules of particular symmetries, but is a simple procedure within the numerical solution algorithm itself. This allows its general use for molecules of arbitrary symmetry. It is demonstrated analytically for a non-linear triatomic model with charges on the end sites, that the SSOZ-HNC equation effectively decouples, with the decoupling being dependent on the difference between the multiplicative and additive means of the radial distribution functions involving only charged sites. This decoupling has the consequence that the structural effe~ts due to the dipolar interactions cancel each other out. This results in the dipolar interactions having little or no effect on the calculated structure factor. The numerical solution to the SSOZ-HNC equation is obtained for a series of hard and soft sphere, non-linear, dipolar, triatomic models. The results obtained show that the dipolar interactions have a very significant effect on the liquid structure but that this is not reflected in the corresponding structure factor due to the effective decoupling of the integral equation. This effective decoupling phenomenon is predicted to apply to a range of dipolar molecular liquids. To test this, the SSOZ-HNC equation is solved for an interaction site potential model for the highly dipolar, but non-hydrogen bonded liquid, acetonitrile. The radial distribution functions obtained show that the dipolar interactions have a significant effect on the liquid structure. However, as predicted, there is very little effect on the calculated scattering function. Also, there is very good agreement between the calculated and experimental neutron scattering, coherent differential cross section. Comparison of the SSOZ-HNC radial distribution functions and internal energies with molecular dynamics simulation results from the literature f~r the same potential showed overall, very good agreement. From these results, it was also concluded that there are two dominant, nearest neighbour orientations in liquid acetonitrile due to the dipolar interactions.

In this picture X is given by a divisorial fan on a smooth projective curve Y. Cartier divisors on X can be described by piecewise affine functions h on the divisorial fan S whereas Weil divisors correspond to certain zero and one dimensional faces of it. Furthermore we provide descriptions of the divisor class group and the canonical divisor. Global sections of line bundles O(D_h) will be determined by a subset of a weight polytope associated to h, and global sections of specific line bundles on the underlying curve Y.

description: The syntheses of 8-amino-16-azadispiro[6.1.6.2]heptadecan-16-one and its 8-chloroacetyl derivative are reported. The compounds were characterized by their infrared spectra and by elemental analysis of the latter compound. Data is presented for the attempted reaction of dimethylaminoacetic acid with 7-amino-14-azadispiro[5.1.5.2]pentadecan-15-one and 8-amino-16-azadispiro-[6.1.6.2]heptadecan-17-one using dicyclohexylcarbodiimide as the condensing reagent. The reduction of the product obtained from the latter reaction is described. The addition of the ß-dimethylaminoethyl group to the 8-amino dispiro compound named above, in the presence of sodamide was also tried. A ß-dimethylaminoethyl derivative of 7,14-diazadispiro[5.1.5.2]penta-decane was synthesized by the lithium aluminum hydride reduction of the pentadecan-15-one analog. A correct elemental analysis was obtained for the unsaturated compound but the reduced derivative was identified only by its infrared spectrum. It was not determined whether substitution had occurred at the secondary or the lactam nitrogen. The reaction of chloroacetyl chloride with 7,14-diazadispiro[5.1.5.2]pentadecan-15-one using a variety of reaction conditions is described. Data is also presented for the attempted purification of the product obtained from the latter reaction; both thin layer and column chromatography were employed. The condensation reaction of 1-amino-cycloheptanecarbonitrile in the presence of sodium ethoxide and a trace of moisture does not yield the expected 8,16-diazadispiro[6.1.6.2]heptadecan-17-one.

description: ZrCu-based bulk metallic glass composites (BMGCs) are well known for their plastic deformability, superior to traditional metallic glasses (MGs), which is attributed to a unique dual-phases structure, namely, the glassy matrix and unstable B2 phase. In the present study, in-situ tensile testing is used to trace the deformation process of a ZrCu-based BMGC. Three deformation stages of the BMGC, i.e., the elastic-elastic stage, the elastic-plastic stage, and the plastic-plastic stage are identified. In the elastic-elastic and elastic-plastic stages, the yield strength and elastic limit are major influenced by the volume fraction of the B2 crystals. In the plastic-plastic stage, the B2 phase stimulates the formation of multiple shear bands and deflects the direction of shear bands by disturbing the stress field in front of the crack tip. The deformation-induced martensitic transformation of the metastable B2 phase contributes to the plasticity and work hardening of the composite. This study highlights the formation and propagation of multiple shear bands and reveals the interactions of shear bands with structural heterogeneities in situ. Especially, the blocking of shear bands by crystals and the martensitic transformation of the B2 phase are critical for the mechanistic deformation process and illustrate the function of the B2 phase in the present BMGCs.

description: For a Hopf algebra B, we endow the Heisenberg double H(B^*) with the structure of a module algebra over the Drinfeld double D(B). Based on this property, we propose that H(B^*) is to be the counterpart of the algebra of fields on the quantum-group side of the Kazhdan--Lusztig duality between logarithmic conformal field theories and quantum groups. As an example, we work out the case where B is the Taft Hopf algebra related to the U_qsl(2) quantum group that is Kazhdan--Lusztig-dual to (p,1) logarithmic conformal models. The corresponding pair (D(B),H(B^*)) is "truncated" to (U_qsl(2),H_qsl(2)), where H_qsl(2) is a U_qsl(2) module algebra that turns out to have the form H_qsl(2)=\oC_q[z,d]\tensor C[λ]/(λ^{2p}-1), where C_q[z,d] is the U_qsl(2)-module algebra with the relations z^p=0, d^p=0, and d z = q-q^{-1} + q^{-2} zd.

Bridging the science-policy gap: An examination using case studies on sea level rise in Tasmania
Creators: name: Summers, A
Publisher: name: University Of Tasmania

description: Environmental issues are increasingly a global concern and have expanded in scale, scope and complexity. Informed policy decisions can mitigate or avoid environmental problems, but this requires effective integration of science into policy. This thesis examines factors which affect the integration of science into policy and ways to improve this process. The methodology included an extensive consideration of the literature, three case studies (sea level rise managed by Clarence City Council, the Derwent Estuary Program and the Shack Sites Project), an internet survey and key informant interviews. The results indicate that the factors identified in the literature as affecting the integration of science into policy can be divided into two categories according to their influence in practice. Some of the factors (communication, recognition of constraints and respect for scientific information) were perceived to affect the integration of science into policy. However, other factors (role of scientists, timeframes and presentation of relevant information) were not perceived to affect the incorporation of science into policy in practice. The results also indicated that the most effective way to improve the process would be to increase face-to-face interactions between scientists and policymakers. Intermediaries were also shown to improve the integration of science into policy in many cases.
Descriptive survey of the parents of mildly retarded children

description: Mildly retarded children provide special problems for many professional disciplines giving services to children in our society. This study is intended to describe the nature of the performance and/or behavioral traits of these children which influenced parents to seek help from a professional person or influenced a professional person to give services to the child and his family. A sample of 65 children was selected from the Vancouver school system's Special classes for slow learners. Their parents were interviewed during the summer of 1967 by one interviewer. The difficulties that were described by parents were not limited to developmental lags or learning problems. They also included behavior problems in the home and community. The observations of this survey indicated that the nature of the problems, as felt by the parents, tended to change as the child passed through the childhood stages of development. The problems corresponded very closely to society's expectations as related to age-appropriate performance and behavior of the normal child. The type of help that was sought by the parents reflected the changing nature of their assessment of the problems. In infancy, the help sought was predominantly medical. In the toddler and preschool stages the type of help sought changed gradually from medical to educational and social services. During the school-age stage, the parents sought help from the greatest variety of sources, mainly from the school, but also including public health nurses, social workers, psychologists and psychiatrists. Factors other than the child's performance and/or behavior appeared to influence the patterns of help-seeking found among the parents but these were not fully assessed by this study. The parents were not always realistic in their appraisals of their child's abilities. Feelings of ambivalence, confusion and anxiety regarding the child's problems and the various professionals involved, were frequently noted. To generalize these findings from this sample of children in Special classes to the whole population of mildly retarded children was made difficult, by the method of sampling but one might speculate that differences between this sample and the population would be differences of degree rather than kind.
A new description of probability density distributions of polar mesospheric clouds

description: In this paper we present a new description of statistical probability density functions (pdfs) of polar mesospheric clouds (PMCs). The analysis is based on observations of maximum backscatter, ice mass density, ice particle radius, and number density of ice particles measured by the ALOMAR Rayleigh-Mie-Raman lidar for all PMC seasons from 2002 to 2016. From this data set we derive a new class of pdfs that describe the statistics of PMC events that is different from previous statistical methods using the approach of an exponential distribution commonly named the g distribution. The new analysis describes successfully the probability distributions of ALOMAR lidar data. It turns out that the former g-function description is a special case of our new approach. In general the new statistical function can be applied to many kinds of different PMC parameters, e.g., maximum backscatter, integrated backscatter, ice mass density, ice water content, ice particle radius, ice particle number density, or albedo measured by satellites. As a main advantage the new method allows us to connect different observational PMC distributions of lidar and satellite data, and also to compare with distributions from ice model studies. In particular, the statistical distributions of different ice parameters can be compared with each other on the basis of a common assessment that facilitates, for example, trend analysis of PMC. © Author(s) 2019.
Distributions of charged massive scalars and fermions from evaporating higher-dimensional black holes

description: A detailed numerical analysis is performed to obtain the Hawking spectrum for charged, massive brane scalars and fermions on the approximate background of a brane charged rotating higher-dimensional black hole constructed in arXiv:0907.5107. We formulate the problem in terms of a "spinor-like" first order system of differential wave equations not only for fermions, but for scalars as well and integrate it numerically. Flux spectra are presented for non-zero mass, charge and rotation, confirming and extending previous results based on analytic approximations. In particular we describe an inverted charge splitting at low energies, which is not present in four or five dimensions and increases with the number of extra dimensions. This provides another signature of the evaporation of higher-dimensional black holes in TeV scale gravity scenarios.

Heavy lepton pair production at LHC: model discrimination with multi-lepton signals

description: If new leptons exist close to the electroweak scale, they can be produced in pairs at LHC through standard or new interactions. We study the production of heavy lepton pairs in SM extensions with: (i) a Majorana or Dirac lepton triplet, as those appearing in type-III seesaw; (ii) a lepton isodoublet (N,E)_{L,R}; (iii) a charged isosinglet E_{L,R}; (iv) a Majorana or Dirac neutrino singlet N and an additional Z' gauge boson. It is shown that the trilepton final state l+-l+-l-+, which has a small SM background, constitutes the golden channel for heavy neutrino searches, being very sensitive to Majorana or Dirac neutrinos in triplet, doublet or singlet SU(2)_L representations. For higher luminosities, signals in this final state can also distinguish lepton triplets from doublets and singlets. The Majorana or Dirac nature of the heavy neutrinos is revealed by the presence or not of like-sign dilepton l+-l+- signals without significant missing energy. Notably, l+-l+- signals but with large missing energy are characteristic of Dirac triplets, distinguishing them from the other two models with a heavy Dirac neutrino. Further discrimination is achieved with the analysis of the clean l+l+l-l- final state.

Blanche DuBois: A Woman's Journey from Belle Reve through Tarantula Arms to The Elysian Fields
Creators: name: Comanelea, Raluca Daniela
Publisher: name: University of Nevada, Las Vegas
Year: 2019

description: This present thesis aims at deconstructing the main character of A Streetcar Named Desire by Tennessee Williams: Blanche DuBois. Blanches journey is traced from Death to Desire and finally, to an ultimate envisioned destination, The Elysian Fields, which represents her physical and spiritual burial at sea, with her soul ultimately reaching heaven. Blanches most important quality - her ability to seduce audiences into perceiving the multifaceted layers of her feminine character all at once - marks her entry into Williamss theatre of excess. Her theatricality springs precisely from her fascinating ability to reconstruct her persona in the course of the play, enacting the many possibilities contained in the word Woman. Excess becomes Blanches strategy for recreating possibilities and liberating conflicts. Blanche pours herself out with each page of the play so that every aspect of her identity is presented to the audience. Through the lens of death and desire, the many roles she embodies are analyzed one by one, remaining in strong connection with a close reading of the plays lines. Blanches womanly essence is further captured by the intensity of female actresses who enacted her role on American as well as on the world stage. A Streetcar Named Desire revivals have always experimented with Blanches image, while also making full use of the cultural context of their time. Williams himself experienced struggle in sketching Blanches intense character. His unpublished manuscripts remain testimony of Blanches power as a female character, with a potential to embody the universal woman. Despite her physical rape, Blanche leaves the play and the stage triumphantly, hand in hand with the doctor, smiling, further dreaming of the unwashed grape which will bury her body at sea and transport her soul to heaven.

description: NOAA technical memorandum NMFS-NWFSC ; 185
description: This document was originally developed for internal use by the Northwest Fisheries Science Center (NWFSC) Fisheries Resource, Analysis and Monitoring Division (FRAM) field staff. Designed as a pictorial list to aide identification of the invertebrate taxa captured during the various FRAM West Coast surveys one does not need an advanced degree to use it. Therefore scientific and technical terms have been kept to a minimum and, when used, are defined within the text. Descriptions and distribution are confined to those species within the geographic (U.S.–Canada to U.S.–Mexico borders) and depth (30–1,680 m) parameters of the FRAM West Coast surveys. Many of the invertebrates described have geographic and/or depth ranges that extend outside of the survey parameters. Distributions include these areas and are described by political boundaries (e.g., state and/or country borders), bodies of water (i.e., the northeastern Pacific, the Strait of Juan de Fuca, the Columbia River, etc.), islands and/or major geographical features (i.e., the Hawaiian, Farallon, and Channel Islands, Cape Flattery, Point Conception, etc.).
