CLASSIFIERS BASED ON A NEW APPROACH TO ESTIMATE THE FISHER SUBSPACE AND THEIR APPLICATIONS
Creators: name: ROZZA, ALESSANDRO
Publisher: name: Universit� degli Studi di Milano
Year: 2011

description: In this thesis we propose a novel classifier, and its extensions, based on a novel estimation of the Fisher Subspace. The proposed classifiers have been developed to deal with high dimensional and highly unbalanced datasets whose cardinality is low. The efficacy of the proposed techniques has been proved by the results achieved on real and synthetic datasets, and by the comparison with state of the art predictors.

description: The overall aim of this project is to investigate the conceptual and empirical validity of Chinese medicine in Australia. To this end, the work is composed of three main lines of enquiry. In the first and conceptual component of this work, Chinese medicine (CM) and Western medicine (WM) will be characterised, and the possibility that they satisfy similar fundamental attributes under the conception of a health care profession is explored. The nature and use of evidence in both CM and WM is examined, with the finding that comparisons between the two – particularly in the areas of Evidence Based Medicine (EBM) research, ‘the placebo effect’, and the nature of clinical practice – reveal complex areas of increasingly emerging similarities that are worth further consideration. Areas such as the use and overlap between the domains of quantitative and qualitative methodologies in relation to this work are also discussed. In the interventions that make up the empirical part of this work, a nationwide survey (n =655) and semi-structured interviews (n = 29) attempt to characterise the current workforce nature and attitudes of Chinese medicine practitioners and key stakeholders in Australia. CM practitioners are found to be highly educated, coming from a diversity of backgrounds, and choosing to practise in a sole or multi-practitioner private practice setting. CM practitioners value and display a number of professional attributes, in particular their continuing professional development. They are found to acknowledge a variety of disparate and inter-related forms of evidence in their practice. CM practitioners and key stakeholders are also seen here to be working within and between multiple discourses and modes of thinking regarding the body and illness. They report valuing both CM classical evidence and evidence from EBM research. While they predominantly rely on and value CM theoretical and practical structures, at the same time they are engaged in complex states of conceptual and cultural negotiation between CM and the dominant form of healthcare in Australia, WM. These findings may have implications for how we view the practice of not only CM, but also other forms of healthcare and their evaluation. Finally, the discussion attempts to situate these results within the current Australian healthcare setting and build upon the above enquiries in order to highlight areas of attention that may further enable the development of CM as a mature and relevant healthcare profession in Australia.

description: Hybrid filler systems of multiwalled carbon nanotubes (MWCNTs) and carbon black (CB) were incorporated into two types of polyamide 12 (PA12) using small-scale melt mixing in order to identify potential synergistic effects on the interaction of these two electrical conductive fillers. Although no synergistic effects were observed regarding the electrical percolation threshold, at loadings well above the percolation threshold higher volume conductivities were obtained for samples containing both, MWCNT and CB, as compared to single fillers. This effect was more pronounced when using a higher viscous PA12 matrix. The formation of a co-supporting network can be assumed. The combined use of CB and MWCNTs improved the macrodispersion of MWCNT agglomerates, which can be assigned as a synergistic effect. DSC measurements indicated an effect of the nanofiller on crystallisation temperatures of PA12; however this was independent of the kind or amount of the carbon nanofiller. © 2011 Elsevier Ltd.

description: Weight gain increases the prevalence of obesity, a risk factor for cardiovascular disease. Nevertheless, unintentional weight loss can be a harbinger of health problems. The Atherosclerosis Risk in Communities Study (1987–2009) included 15,792 US adults aged 45–64 years at baseline and was used to compare associations of long-term (30 years) and short-term (3 years) weight change with the risks of coronary heart disease (CHD) and ischemic stroke. Age-, gender-, and race-standardized incidence rates were 4.9 (95% confidence interval (CI): 4.6, 5.2) per 1,000 person-years for CHD and 2.5 (95% CI: 2.3, 2.8) per 1,000 person-years for stroke. After controlling for baseline body mass index and other covariates, long-term weight gain (since age 25 years) of more than 2.7% was associated with elevated CHD risk, and any long-term weight gain was associated with increased stroke risk. Among middle-aged adults, short-term (3-year) weight loss of more than 3% was associated with elevated immediate CHD risk (hazard ratio = 1.46, 95% CI: 1.18, 1.81) and stroke risk (hazard ratio = 1.45, 95% CI: 1.10, 1.92). Risk tended to be larger in adults whose weight loss did not occur through dieting. Avoidance of weight gain between early and middle adulthood can reduce risks of CHD and stroke, but short-term, unintentional weight loss in middle adulthood may be an indicator of immediate elevated risk that has not previously been well recognized.

description: Ball milling of carbon nanotubes (CNTs) in the dry state is a common way to produce tailored CNT materials for composite applications, especially to adjust nanotube lengths. For NanocylTM NC7000 nanotube material before and after milling for 5 and 10h the length distributions were quantified using TEM analysis, showing decreases of the mean length to 54% and 35%, respectively. With increasing ball milling time in addition a decrease of agglomerate size and an increase of packing density took place resulting in a worse dispersability in aqueous surfactant solutions. In melt mixed CNT/polycarbonate composites produced using masterbatch dilution step, the electrical properties, the nanotube length distribution after processing, and the nano- and macrodispersion of the nanotubes were studied. The slight increase in the electrical percolation threshold in the melt mixed composites with ball milling time of CNTs can be assigned to lower nanotube lengths as well as the worse dispersability of the ball milled nanotubes. After melt compounding, the mean CNT lengths were shortened to 31%, 50%, and 66% of the initial lengths of NC7000, NC7000-5h, and NC7000-10h, respectively. © 2011 Elsevier Ltd.

description: We demonstrate a gain-switched thulium fiber laser that can be continuously tuned over 140 nm, while maintaining stable nanosecond single-pulse operation. To the best of our knowledge, this system represents the broadest tuning range for a gain-switched fiber laser. The system simplicity and wideband wavelength tunability combined with the ability to control the temporal characteristics of the gain-switched pulses mean this is a versatile source highly suited to a wide range of applications in the eye-safe region of the infrared, including spectroscopy, sensing and material processing, as well as being a practical seed source for pumping nonlinear processes.

description: The influence of feeding conditions of multiwalled carbon nanotube (MWCNT) materials, namely Baytubes® C150P and Nanocyl™ NC7000, into polypropylene (PP) was investigated with respect to achieving suitable nanotube dispersion, high electrical conductivity, and good mechanical properties. Both MWCNT materials were fed at selected concentrations either in the hopper of the twin-screw extruder or using a side feeder under otherwise identical extrusion conditions (rotation speed, throughput, temperature profile) using a Berstorff ZE 25 twin-screw extruder. Afterwards, injection molding was performed under identical conditions. The results indicate that the more compact Baytubes® C150P agglomerates should be added into the hopper, as the dispersion assessed by light microscopy is better, electrical resistivities measured on compression and injection molded samples are lower, and elastic modulus, yield strength and impact strength are higher as compared to side feeding. On the other hand, for the more loosely packed Nanocyl™ NC7000 agglomerates, addition using the side feeder leads to better dispersion, lower electrical resistivity, and higher mechanical properties. © 2011 Elsevier Ltd.

description: Nourdin et al. [9] established the following universality result: if a sequence of off-diagonal homogeneous polynomial forms in i.i.d. standard normal random variables converges in distribution to a normal, then the convergence also holds if one replaces these i.i.d. standard normal random variables in the polynomial forms by any independent standardized random variables with uniformly bounded third absolute moment. The result, which was stated for polynomial forms with a finite number of terms, can be extended to allow an infinite number of terms in the polynomial forms. Based on a contraction criterion derived from this extended universality result, we prove a central limit theorem for a strongly dependent nonlinear processes, whose memory parameter lies at the boundary between short and long memory.

description: The effect of ball milling on the structural characteristics and further on the dispersion and percolation behaviour of multiwalled carbon nanotubes (MWCNTs) in melt mixed composites using a maleic anhydride modified isotactic polypropylene as matrix was investigated. TEM and SEM revealed that ball milled nanotubes were considerably shorter and showed a compact primary agglomerate morphology compared to the as-synthesised MWCNTs. At macro scale ball milled MWCNTs were found to be better dispersed, whereas at sub-micron scale the states of dispersion of both nanotube materials were comparable. The differences in the composite morphologies as well as in the composites electrical and rheological percolation behaviour were assigned to the altered MWCNT structure due to ball milling treatment. The dispersibility of ball milled MWCNTs was restricted due to their more compact agglomerate morphology. Furthermore, the ability to form percolated network structures was restrained by their shorter length and, again, their compact primary agglomerates. An effective agglomerate interaction radius depending on the nanotube structural characteristics, length and agglomerate morphology, is suggested in order to explain the experimental findings. © 2011 Elsevier Ltd.

description: Taking wedge products of the $p$ distinct principal null directions associated with the eigen-bivectors of the Weyl tensor associated with the Petrov classification, when linearly independent, one is able to express them in terms of the eigenvalues governing this decomposition. We study here algebraic and differential properties of such $p$-forms by completing previous geometrical results concerning type I spacetimes and extending that analysis to algebraically special spacetimes with at least 2 distinct principal null directions. A number of vacuum and nonvacuum spacetimes are examined to illustrate the general treatment.

description: Studying empirically derived dietary patterns is useful in understanding dietary practice. We classified women by their dietary patterns using latent class analysis of 66 foods and studied the association of these patterns with neural tube defects (NTDs) and congenital heart defects (CHDs) in the US National Birth Defects Prevention Study (1997–2005). Logistic regression models used data from 1,047 with an NTD, 6,641 with a CHD, and 6,123 controls that were adjusted for maternal characteristics and tested the effect modification of multivitamin supplement use. Four latent dietary patterns were identified: prudent, Western, low-calorie Western, and Mexican. Among participants who did not use supplements, those in the Mexican, Western, and low-calorie Western classes were significantly more likely (odds ratios of 1.6, 1.5, and 1.4, respectively) to have offspring born with NTDs than were those in the prudent class after adjustment of for dietary folic acid intake. In contrast, among supplement users, there was no difference in the incidence of NTDs between classes. Associations between dietary class and CHD subgroups were not modified by supplement use except for tetralogy of Fallot; among supplement users, those in the Western class were twice as likely (95% confidence interval: 1.4, 2.8) as the prudent class to have offspring with tetralogy of Fallot. Women who adhered to a Western diet were 1.2 (95% confidence interval: 1.03, 1.35) times more likely to have an infant with septal heart defect than were women who adhered to a prudent diet. A prudent dietary pattern, even with folate fortification, may decrease the risk of NTDs and some heart defects.

description: Abstract: MOSFET mismatch measurements and characterization are repetitive tasks that require a huge amount of measurements, testing time, and data post-processing. In this presentation, an array test structure and a measurement method are proposed. They extraordinarily improve mismatch measurement time with a reduced equipment setup, while maintaining a high statistical confidence level. The structure is based on the combination of two stacked MOS transistors and the measurement methodology relies on just two single DC voltage measurements. With a theoretical speed improvement of 30x, the method enables fast extraction of MOSFET mismatch parameters, useful to designers, such as AVTH and Aβ with less than 2% error. The data correlation coefficient between the traditional and the proposed method is not less than 0.94, obtained in bulk CMOS test chips, thus confirming the high statistical confidence of the extraction method.
Retrospection and prodigy: a studio research project incorporating memory and childhood as a construct for generating new ceramic sculpture

description: This research paper investigates my childhood, the notion of play expressed in self-made toys and their relationship to my sculptural practice. My studio research has been engaged in forming object-based ceramic works that form a series of hand-built artworks. Another aspect embedded in the studio research was to examine the relationships between ancient ceramic history and customs alongside select contemporary practitioners. My paper also investigates civilizations that created ceramic objects and how I consider these traditions when making sculptures. My process stems from my engagement with childhood memories, in my homeland, as a basis to identify themes of my research project. These ideas integrate my family background, the community I was raised in, happiness and creativity. In identifying symbols surrounding these characteristics throughout my investigation, I have focused on games and toys emanating from a particular time of my childhood. My studio research, the creation of ceramic sculptures that have permanent material qualities, has been a personal pursuit, in an attempt to understand my own cultural origins combine with childhood memory. This aim has required me to travel back to my hometown of Kampung Baru, Jitra, Kedah, in Malaysia. The journey allowed me to contemplate my past, document my surroundings and re-experience the process of fabricating self-made toys. Through identification and selection of such objects, studio research and a number of technical strategies implemented such as: material investigations, prototype studies, kiln tests and surface treatments − were all examined as a basis in for producing sculptural forms. This document is divided into five segments. The first Chapter highlights childhood experiences including play and resourcefulness. The second Chapter explores types of toys and games in childhood. Chapter Three focuses on sculptural elements and influences from various prominent artists. In Chapter Four, studio methodologies are examined using clay-slip and absorbent materials. Chapter Five expands on conceptual approaches to ceramic sculpture as relevant to this thesis. The studio research distinguishes itself from the production of other contemporary ceramic sculptors through adopting a hybrid approach of using clay and fabric as a vehicle for driving innovation and expression. And, by incorporating my cultural background and memories of childhood and those objects significant to me, this thesis brings together a personal artistic case-study that highlights my journey of discovery, contemplation and creative engagement.

description: One of the fundamental postulates of the special relativity theory is existence of a single system of universal coordinate transforms for inertial reference frames, that is coordinate transforms, which are uniquely determined by space-time coordinates of a material point. In this paper the abstract mathematical theory of coordinate transforms in kinematic changeable sets is developed. In particular it is proved the formal possibility of existence of kinematics, which do not allow universal coordinate transforms. Such kinematics may be applied for simulation the evolution of physical systems under the condition of hypothesis on existence of particle-dependent velocity of light.

The role of large-scale organisation of convection for tropical weather and climate
Creators: name: Tan, Boon Sze Jackson
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: Tropical deep convection is a critical process in the climate system, influencing quantities such as cloud cover, precipitation and circulation. Despite its importance, convection is poorly represented in global climate models (GCMs). This shortcoming manifests through significant model biases such as in tropical clouds, precipitation and variability on various time scales, and limits our ability to make accurate projections such as changes in rainfall patterns in a warming climate. Due to the coarse resolution of GCMs, convection has to be represented through parametrisation schemes, in which the subgrid-scale behaviour of convection is determined through the resolved large-scale variables. However, our understanding of the relationship between large-scale variables and convection of different degrees of organisation is limited. In this thesis, we investigate the properties and organisation of tropical convection using cloud regimes, with the aim of improving the representation of convection in models. These cloud regimes are derived from the International Satellite Cloud Climatology Project and they identify various states of convection at a resolution comparable to a GCM. These states range from convectively-suppressed environments to a convectively-active atmosphere of congestus clouds and one with cirrus clouds to, most importantly, a regime of organised deep convection. Using these cloud regimes as proxies for different states of convection, we examine its relationship to large-scale variables. Compositing the cloud regimes with traditional measures of convection, we ascertain that they indeed represent different states of convection. Relating them to large-scale variables, we discover that the environments of different convective states are statistically distinct but possess considerable overlap, a result consistent with the stochastic nature of the relationship between convection and large-scale variables. This motivates us to use our knowledge of this relationship to investigate convective organisation in statistical models of varying complexity. After extending the resolution of the regimes from one day to three hours through an innovative technique, we model them statistically using its large-scale environment and infer that a stochastic parametrisation scheme that ignores spatial and temporal memory may struggle to reproduce deep convection organised beyond the grid box and time step. This outcome is worrying because an analysis of the time-series of these regimes suggests that organised deep convection has increased in the past twenty-seven years, driving a corresponding change in the spatial trends of precipitation. Therefore, advancing our understanding of deep convection and addressing deficiencies in its representation in GCMs are of paramount importance.

description: Commercial Udel® poly(ether sulfone) (PSU) was filled with three different commercially available multiwalled carbon nanotubes (MWCNTs) by small scale melt mixing. The MWCNTs were as grown NC 7000 and two of its derivatives prepared by ball milling treatment. One of them was unmodified (NC 3150); the other was amino modified (NC 3152). The main difference beside the reactivity was the reduced aspect ratio of NC 3150 and NC 3152 caused by ball milling process. All PSU/MWCNT composites with similar filler content were prepared under fixed processing conditions and comparative analysis of their electrical and mechanical properties were performed and were correlated with their microstructure, characterized by optical microscopy, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). A non-uniform MWCNT dispersion was observed in all composites. The MWCNTs were present in form of agglomerates in the size of 10-60. μm whereas the deagglomerated part was homogeneously distributed in the PSU matrix. The differences in the agglomeration states correlate with the variations of properties between different PSU/MWCNT composites. The lowest electrical percolation threshold of 0.25-0.5. wt.% was observed for the shortened non-functionalized MWCNT composites and the highest for amine-modified MWCNT composites (ca. 1.5. wt.%). The tensile behavior of the three composites was only slightly altered with CNT loading as compared to the pure PSU. However, the elongation at break showed a reduction with MWCNT loading and the reduction was least for composite with best MWCNT dispersion. © 2012 Elsevier Ltd.

description: We present an early analysis on the search for high redshift galaxies using the deepest public JWST imaging to date, the NGDEEP field. This data consists of 6-band NIRCam imaging on the Hubble Ultra Deep Field-Par2, covering a total area of 6.3 arcmin$^{2}$. Based on our initial reduction of the first half of this survey, we reach 5$σ$ depths up to mag = 29.5--29.9 between $1-5$ um. Such depths present an unprecedented opportunity to begin exploring the early Universe with JWST. As such, we find high redshift galaxies in this field by examining the spectral energy distribution of these systems and present 18 new $z > 8$ systems identified using two different photometric redshift codes: LePhare and EAZY, combined with other significance criteria. The highest redshift object in our sample is at $z=15.57^{+0.39}_{-0.38}$, which has a blue beta slope of $β=-3.25^{+0.41}_{-0.46}$ and a very low inferred stellar mass of $M_{*} = 10^{7.39}$ M_0,. We also discover a series of faint, low-mass dwarf galaxies with $M_{*} < 10^{8.5}$ M_0 at $z \sim 9$ that have blue colors and UV slopes. The structure of these galaxies is such that they all have very flat surface brightness profiles and small sizes $< 1 \ \mathrm{kpc}$. We also compare our results to theory, finding no significant disagreement with some CDM based models.The discovery of these objects, most of which are low luminosity and inferred stellar mass, demonstrates the power of probing continuously deeper into the Universe, pointing the way to deeper, or similar depth but wider area, surveys and demonstrate the critical need for JWST deep fields to explore this aspect of the early Universe.

description: The paper reports the effect of using of a three roll mill as additional dispersion step after twin-screw melt extrusion of nanocomposites containing thermoplastic polymers and multiwalled carbon nanotubes. The three roll milling technology was adapted to elevated temperatures of up to 180 °C and examples are shown for its use in processing of different pre-compounded thermoplastic polymer composites based on polypropylene, polycaprolactone and ethylene-vinyl acetate. The aim is to enhance the state of dispersion achieved by the previous melt extrusion step. In particular, depending on the state of dispersion before three roll milling and the adapted conditions, like number of runs and gap sizes, a reduction of number and size of remaining primary nanotube agglomerates was found. This was studied using light microscopy. The resulting improvements in mechanical properties were assessed and could be attributed to the improved dispersion. In some cases agglomerate free samples could be achieved after the three roll milling process. © 2012 Elsevier Ltd.

description: We analyze idealized sequential Stern-Gerlach experiments with higher spin particles. This analysis serves at least two purposes: The widely discussed spin-1/2 case leads to some misunderstandings which hopefully is removed by the higher spin discussion. Secondly, Wigner rotation matrices for generic spins become conceptually more transparent with this physical example. We also give compact formulas for the probabilities in terms of the angle between the sequential SG apparatuses for generic spins. We work out the spin-$1/2$, spin-$1$ and spin-$2$ cases explicitly. Since there are some confusing issues regarding the actual experiment, we also compile a "facts and fiction" section on the SG experiments.

MICROSCOPIC STUDIES OF STATIC AND DYNAMIC PROPERTIES IN QUANTUM LIQUIDS AND GASES

description: In this thesis I present studies of a number of quantum many-body Bose systems via Quantum Monte Carlo methods. We investigated the dynamic structure factor of a hard-sphere Bose system simulated at T=0 at different densities, from the dilute to the strongly interacting regimes. By increasing the density we observed the spectrum evolves from the weakly interacting Bogoliubov to a phonon-maxon-roton dispersion, but also the emergence of a broad multi-quasiparticle component. For a system with sphere radius and density corresponding to superfluid 4He at equilibrium, we found good agreement with the spectrum in the roton region. In another work, a liquid of distinguishable 4He atoms near freezing at T=1 K was studied to compute the equation of state and static density response function. The results of this study have been used to improve the description of the superfluid-to-solid transition within the Density Functional Theory. Measurements of crystallization kinetics in supercooled liquid p-H2--o-D2 mixtures showed a slowdown with respect to the pure counterparts. In order to contribute to the interpretation of these results we simulated these metastable mixtures. We found differences in the quantum delocalization of the two isotopic molecules, which result in different effective sizes. We characterized also the differences in the local order around the molecules of each species. These results revealed that the observed slowdown is due to purely quantum effects. Finally, in a QMC study of ion Ar+ doped 4He nanodroplets at T=1 K, we computed density profiles, energies, and investigated local order around the Ar+ ion. We found stable solid structures around the ion composed of three solvation shells having the shape of platonic solids: an icosahedron, a dodecahedron, and, again, an icosahedron, with 12, 20, and 12 4He atoms, going from the inner to the outer shell respectively. These results confirmed the interpretation of experimental measurements of the abundances of Ar+@4He nanodroplets.

description: We present the SWAP Filter: an azimuthally varying, radial normalizing filter specifically developed for EUV images of the solar corona, named for the Sun Watcher with Active Pixels and Image Processing (SWAP) instrument on the Project for On-Board Autonomy 2 spacecraft. We discuss the origins of our technique, its implementation and key user-configurable parameters, and highlight its effects on data via a series of examples. We discuss the filter's strengths in a data environment in which wide field-of-view observations that specifically target the low signal-to-noise middle corona are newly available and expected to grow in the coming years.

description: When incorporating multiwalled carbon nanotubes (MWCNTs) synthesised by the aerosol-CVD method using different solvents into polyamide 6.6 (PA66) by melt mixing an ultralow electrical percolation threshold of 0.04. wt.% was found. This very low threshold was assigned to the specific characteristic of the MWCNTs for which a very high aspect ratio, a good dispersability in aqueous surfactant dispersions, and relatively low oxygen content near the surface were measured. The investigation of the composites by transmission electron microscopy on ultrathin cuts as well as by scanning electron microscopy combined with charge contrast imaging on compression moulded plates illustrated a good MWCNT dispersion within the PA66 matrix and that the very high aspect ratio of the nanotubes remained even after melt processing. Additionally, the thermal behaviour of the PA66 composites was investigated using differential scanning calorimetry (DSC) showing that the addition of only 0.05. wt.% MWCNT leads to an increase of the onset crystallization temperature of 11. K.
Parasitic relations: thinking beyond interactivity
Creators: name: Goodman, Andrew Bruce
Publisher: name: Monash University
Year: 2019
Subjects: Uncategorized

description: This practice-led research questions what more a participatory work might be able to do beyond prescriptive and linear forms of interactivity in art events. The research develops practical applications of Michel Serres’ concept of the ‘parasite’, the inherent noise that disrupts and multiplies within relation. The possibility of self production and modulation in a participatory event and the potential of intensive disruption as a driver of creativity within the events are the basis for this investigation of models of art that can incorporate a range of environmental forces to generate an ecological set of relations where viewers, art objects and surroundings generate new and shared potentials.
Missing Doses in the Life Span Study of Japanese Atomic Bomb Survivors

description: The Life Span Study of atomic bomb survivors is an important source of risk estimates used to inform radiation protection and compensation. Interviews with survivors in the 1950s and 1960s provided information needed to estimate radiation doses for survivors proximal to ground zero. Because of a lack of interview or the complexity of shielding, doses are missing for 7,058 of the 68,119 proximal survivors. Recent analyses excluded people with missing doses, and despite the protracted collection of interview information necessary to estimate some survivors' doses, defined start of follow-up as October 1, 1950, for everyone. We describe the prevalence of missing doses and its association with mortality, distance from hypocenter, city, age, and sex. Missing doses were more common among Nagasaki residents than among Hiroshima residents (prevalence ratio = 2.05; 95% confidence interval: 1.96, 2.14), among people who were closer to ground zero than among those who were far from it, among people who were younger at enrollment than among those who were older, and among males than among females (prevalence ratio = 1.22; 95% confidence interval: 1.17, 1.28). Missing dose was associated with all-cancer and leukemia mortality, particularly during the first years of follow-up (all-cancer rate ratio = 2.16, 95% confidence interval: 1.51, 3.08; and leukemia rate ratio = 4.28, 95% confidence interval: 1.72, 10.67). Accounting for missing dose and late entry should reduce bias in estimated dose-mortality associations.
The Force Explosion Condition is Consistent with Spherically Symmetric CCSN Explosions

description: One of the major challenges in Core-collapse Supernova (CCSN) theory is to predict which stars explode and which collapse to black holes. Gogilashvili and Murphy (2022) derived an analytic force explosion condition (FEC) and showed that the FEC is consistent with CCSN simulations that use the light-bulb approximation for neutrino heating and cooling. In this follow-up manuscript, we show that the FEC is consistent with the explosion condition when using actual neutrino transport in GR1D simulations (O'CONNOR 2015). Since most 1D simulations do not explode, to facilitate this test, we enhance the heating efficiency within the gain region. To compare the analytic FEC and radiation-hydrodynamic simulations, this manuscript also presents a practical translation of the physical parameters. For example: we replace the neutrino power deposited in the gain region, $L_ντ_g$, with the net neutrino heating in the gain region; rather than assuming that $\dot{M}$ is the same everywhere, we calculate $\dot{M}$ within the gain region; and we use the neutrino opacity at the gain radius. With small, yet practical modifications, we show that the FEC predicts the explosion conditions in spherically symmetric CCSN simulations that use neutrino transport.

description: This dissertation aims at reconstruing Leopold Jessner?s theatre aesthetics through the analysis of his theatrical essays. Jessner was one of the most influential German theatre directors during the Weimar Republic. His figure came along in the cultural landscape in the same years the director?s theatre emerged in both Europe and Germany. Through the analysis, this dissertation also aims at rethinking Jessner?s theatre aesthetics in the artistic and cultural landscape of the Weimar Republic. The second chapter of the dissertation presents Jessner as a theatre director and focusses on the obstacles and labels that prevented a scientific evaluation of his work. The third chapter proposes an analysis of the author?s corpus. In order to shed light on the key aspects of Jessner?s aesthetics, the investigation is organised in four macro-sections: Der Theaterleiter, Zeittheater und Theaterpolitik, Regie und Schauspielkunst and Betrachtungen und Bekenntnisse. The fourth chapter summarises the results of the analysis and presents Jessner?s Stil des Wesentlichen, focussing on its key elements: the dramaturgical method, the role of scenic design, and of the actor and the relationship with the audience. The last section of the chapter investigates the correlation between Jessners? Stil des Wesentlichen, Expressionism and New Objectivity.
