description: The work-related characteristics of an individual act as pegs around which other non-work activities of an individual are scheduled on a day-to-day basis. This study identifies four dimensions of the medium-to-long range work arrangements that are important to day-to-day temporal and spatial characteristics of work patterns (and hence to day-to-day activity-travel schedules). The four dimensions are: (1) Full-time versus part-time employment, (2) Teleworking or not, (3) Inflexible or flexible work schedules, and (4) Regular or alternate shifts. The study then develops a comprehensive taxonomy of work arrangements in each of these four dimensions and empirically analyses the factors impacting the work arrangement decisions along three of these dimensions. The data used for the empirical analysis is drawn from a web-based survey of Austin area commuters conducted between December 2003 and March 2004. The results emphasize the importance of socioeconomic and work-related characteristics of employees in understanding work arrangement decisions. Specifically, the study indicates that young adults and women with children are more likely than other individuals to be in part-time employment. Also, women workers with children in their households, well-educated workers, and medium-to-high income earners are more likely than the overall worker population to telework. Finally, adults in households with very young children (less than 5 years of age) and individuals working in high employment density work locations have a higher propensity than other individuals to have work schedule flexibility

description: Recent approaches to word sense disambiguation (WSD) utilize encodings of the sense gloss (definition), in addition to the input context, to improve performance. In this work we demonstrate that this approach can be adapted for use in multiword expression (MWE) identification by training models which use gloss and context information to filter MWE candidates produced by a rule-based extraction pipeline. Our approach substantially improves precision, outperforming the state-of-the-art in MWE identification on the DiMSUM dataset by up to 1.9 F1 points and achieving competitive results on the PARSEME 1.1 English dataset. Our models also retain most of their WSD performance, showing that a single model can be used for both tasks. Finally, building on similar approaches using Bi-encoders for WSD, we introduce a novel Poly-encoder architecture which improves MWE identification performance.

description: Plasmon and polariton modes are derived for an ideal semi-infinite (half-space) plasma and an ideal plasma slab by using a general, unifying procedure, based on equations of motion, Maxwell's equations and suitable boundary conditions. Known results are re-obtained in much a more direct manner and new ones are derived. The approach consists of representing the charge disturbances by a displacement field in the positions of the moving particles (electrons). The dielectric response and the electron energy loss are computed. The surface contribution to the energy loss exhibits an oscillatory behaviour in the transient regime near the surfaces. The propagation of an electromagnetic wave in these plasmas is treated by using the retarded electromagnetic potentials. The resulting integral equations are solved and the reflected and refracted waves are computed, as well as the reflection coefficient. For the slab we compute also the transmitted wave and the transmission coefficient. Generalized Fresnel's relations are thereby obtained for any incidence angle and polarization. Bulk and surface plasmon-polariton modes are identified. As it is well known, the field inside the plasma is either damped (evanescent) or propagating (transparency regime), and the reflection coefficient for a semi-infinite plasma exhibits an abrupt enhancement on passing from the propagating regime to the damped one (total reflection). Similarly, apart from characteristic oscillations, the reflection and transmission coefficients for a plasma slab exhibit an appreciable enhancement in the damped regime.

description: Pain is a serious worldwide health problem that affects a vast proportion of the population. For efficient pain management and treatment, accurate classification and evaluation of pain severity are necessary. However, this can be challenging as pain is a subjective sensation-driven experience. Traditional techniques for measuring pain intensity, e.g. self-report scales, are susceptible to bias and unreliable in some instances. Consequently, there is a need for more objective and automatic pain intensity assessment strategies. In this paper, we develop PainAttnNet (PAN), a novel transfomer-encoder deep-learning framework for classifying pain intensities with physiological signals as input. The proposed approach is comprised of three feature extraction architectures: multiscale convolutional networks (MSCN), a squeeze-and-excitation residual network (SEResNet), and a transformer encoder block. On the basis of pain stimuli, MSCN extracts short- and long-window information as well as sequential features. SEResNet highlights relevant extracted features by mapping the interdependencies among features. The third module employs a transformer encoder consisting of three temporal convolutional networks (TCN) with three multi-head attention (MHA) layers to extract temporal dependencies from the features. Using the publicly available BioVid pain dataset, we test the proposed PainAttnNet model and demonstrate that our outcomes outperform state-of-the-art models. These results confirm that our approach can be utilized for automated classification of pain intensity using physiological signals to improve pain management and treatment.

Reduction types and intensionality in the lambda-calculus
Creators: name: Wright, David Amson
Publisher: name: University Of Tasmania
Year: 2023

description: In this thesis I introduce a new approach to the automated analysis of the reduction behaviour of A-calculus terms. This new approach improves on earlier analysers in several ways, not least in its treatment of higher-order terms and polymorphism, two notably troublesome issues. In addition, this thesis introduces a stronger notion of reduction behaviour than strictness. This concept, called strong head neededness, forms the basis for a new notation for describing the reduction behaviour of terms. This notation is a kind of type, elements of which are built using a Boolean algebra of function type constructors. Thus the form of the methodology proposed is that of a type system. Consideration is given to a variety of type assignment systems for the new type system. This supports the hypothesis that the approach proposed is suitable as a framework for building a range of analyses. Having established this framework it is then a matter of engineering to determine the appropriate trade off between information derived and performance achieved. An investigation is conducted into the formal semantics of all the constructs introduced. In particular, the investigation proves a range of soundness and completeness results. Also examined is the semantics of the new notion of type and the development of a model for reduction types. The model is of interest in its own right, as it gives further insight into the reduction behaviour of A-terms. The thesis includes detailed implementations of all the type assignment systems and ascertains the correctness of these implementations.

description: Deep Neural Networks (DNNs) and their accelerators are being deployed ever more frequently in safety-critical applications leading to increasing reliability concerns. A traditional and accurate method for assessing DNNs' reliability has been resorting to fault injection, which, however, suffers from prohibitive time complexity. While analytical and hybrid fault injection-/analytical-based methods have been proposed, they are either inaccurate or specific to particular accelerator architectures. In this work, we propose a novel accurate, fine-grain, metric-oriented, and accelerator-agnostic method called DeepVigor that provides vulnerability value ranges for DNN neurons' outputs. An outcome of DeepVigor is an analytical model representing vulnerable and non-vulnerable ranges for each neuron that can be exploited to develop different techniques for improving DNNs' reliability. Moreover, DeepVigor provides reliability assessment metrics based on vulnerability factors for bits, neurons, and layers using the vulnerability ranges. The proposed method is not only faster than fault injection but also provides extensive and accurate information about the reliability of DNNs, independent from the accelerator. The experimental evaluations in the paper indicate that the proposed vulnerability ranges are 99.9% to 100% accurate even when evaluated on previously unseen test data. Also, it is shown that the obtained vulnerability factors represent the criticality of bits, neurons, and layers proficiently. DeepVigor is implemented in the PyTorch framework and validated on complex DNN benchmarks.

description: We report Raman measurements on Bi2Sr2CaCu2O8+d single crystals which allow us to quantitavely evaluate the doping dependence of the density of Cooper pairs in the superconducting state. We show that the drastic loss of Cooper pairs in the antinodal region as the doping level is reduced, is concomitant with a deep alteration of the quasiparticles dynamic above Tc and consistent with a pseudogap which competes with superconductivity. Our data also reveal that the overall density of Cooper pairs evolves with doping, distinctly from the superfluid density above the doping level pc=0.2.

description: We study superconformal indices of $4d$ compactifications of the $6d$ minimal $(D_{N+3},D_{N+3})$ conformal matter theories on a punctured Riemann surface. Introduction of supersymmetric surface defect in these theories is done at the level of the index by the action of the finite difference operators on the corresponding indices. There exist at least three different types of such operators according to three types of punctures with $A_N, C_N$ and $\left(A_1\right)^N$ global symmetries. We mainly concentrate on $C_2$ case and derive explicit expression for an infinite tower of difference operators generalizing the van Diejen model. We check various properties of these operators originating from the geometry of compactifications. We also provide an expression for the kernel function of both our $C_2$ operator and previously derived $A_2$ generalization of van Diejen model. Finally we also consider compactifications with $A_N$-type punctures and derive the full tower of commuting difference operators corresponding to this root system generalizing the result of our previous paper.

description: The neonatal sepsis continues to be an important public health problem in many countries. In Ecuador, it represents one of the main causes of morbidity and mortality among newborns, especially in premature or low birth weight neonates. The diagnosis is based on the presence of risk factors, clinical criteria, inflammation-infection markers, and alterations in the blood count, as well as the performance of blood cultures. It is essential to identify the origin of the infection and isolate the pathogen, although this is not always possible. Healthcare providers should initiate empirical antibiotic therapy as soon as sepsis is suspected, and subsequent adjustments should be based on the antibiogram, preferably in short-duration regimens and with close monitoring.Consideration should be given to de-escalating the treatment once the infectious focus is controlled. The most serious complications of neonatal sepsis include meningitis, septic shock, and death. The appropriate and rational use of antibiotics, along with the early identification of at-risk neonates, can help reduce the incidence of neonatal sepsis. The sepsis treatment protocol of the Hospital Gineco Obstetrico Isidro Ayora is presented, a tertiary care center that has been attending the most complex obstetric and perinatal cases since its inauguration. This protocol was conducted following the guidelines outlined in A Reporting Tool for Practice Guidelines in Health Care: The RIGHT Statement.

description: Crystal structure and magnetic properties of the layered vanadium phosphate PbZnVO(PO4)2 are studied using x-ray powder diffraction, magnetization and specific heat measurements, as well as band structure calculations. The compound resembles AA'VO(PO4)2 vanadium phosphates and fits to the extended frustrated square lattice model with the couplings J(1), J(1)' between nearest-neighbors and J(2), J(2)' between next-nearest-neighbors. The temperature dependence of the magnetization yields estimates of averaged nearest-neighbor and next-nearest-neighbor couplings, J(1) ~ -5.2 K and J(2) ~ 10.0 K, respectively. The effective frustration ratio alpha=J(2)/J(1) amounts to -1.9 and suggests columnar antiferromagnetic ordering in PbZnVO(PO4)2. Specific heat data support the estimates of J(1) and J(2) and indicate a likely magnetic ordering transition at 3.9 K. However, the averaged couplings underestimate the saturation field, thus pointing to the spatial anisotropy of the nearest-neighbor interactions. Band structure calculations confirm the identification of ferromagnetic J(1), J(1)' and antiferromagnetic J(2), J(2)' in PbZnVO(PO4)2 and yield J(1)'-J(1) ~ 1.1 K in excellent agreement with the experimental value of 1.1 K, deduced from the difference between the expected and experimentally measured saturation fields. Based on the comparison of layered vanadium phosphates with different metal cations, we show that a moderate spatial anisotropy of the frustrated square lattice has minor influence on the thermodynamic properties of the model. We discuss relevant geometrical parameters, controlling the exchange interactions in these compounds, and propose a new route towards strongly frustrated square lattice materials.

description: Stellar perturbations affect planet-formation in binary systems. Recent studies show that the planet-formation stage of mutual accretion of km-sized planetesimals is most sensitive to binary effects. In this paper, the condition for planetesimal accretion is investigated around Alpha CenB, which is believed to be an ideal candidate for detection of an Earth-like planet in or near its habitable zone(0.5-0.9 AU). A simplified scaling method is developed to estimate the accretion timescale of the planetesimals embedded in a protoplanetary disk. Twenty-four cases with different binary inclinations(i_B=0, 0.1, 1.0, and 10 deg), gas densities(0.3,1,and 3 times of the Minimum Mass of Solar Nebula, MMSN hereafter), and with and without gas depletion, are simulated. We find: (1)...(2)...(3)...(4)...(see the paper for details). In other words, our results suggest that formation of Earth-like planets through accretion of km-sized planetesimals is possible in Alpha CenB, while formation of gaseous giant planets is not favorable.

Real time optical images of objects that have been transilluminated with ultrasonic waves in a liquid medium can be obtained. The liquid surface acts as a detector of the ultrasonic energy. When coherent light is reflected off the liquid surface an optical image of the object is obtained. An analysis is presented of the mechanisms involved including an analysis of the transient motion of the liquid surface.

description: The dynamical properties of nuclei, carried by the concept of phonon quasiparticles (QP), are central to the field of condensed matter. While the harmonic approximation can reproduce a number of properties observed in real crystals, the inclusion of anharmonicity in lattice dynamics is essential to accurately predict properties such as heat transport or thermal expansion. For highly anharmonic systems, non perturbative approaches are needed, which result in renormalized theories of lattice dynamics. In this article, we apply the Mori-Zwanzig projector formalism to derive an exact generalized Langevin equation describing the quantum dynamics of nuclei in a crystal. By projecting this equation on quasiparticles in reciprocal space, and with results from linear response theory, we obtain a formulation of vibrational spectra that fully accounts for the anharmonicity. Using a mode-coupling approach, we construct a systematic perturbative expansion in which each new order is built to minimize the following ones. With a truncation to the lowest order, we show how to obtain a set of self-consistent equations that can describe the lineshapes of quasiparticles. The only inputs needed for the resulting set of equations are the static Kubo correlation functions, which can be computed using (fully quantum) path-integral molecular dynamics or approximated with (classical or ab initio) molecular dynamics. We illustrate the theory with an application on fcc 4He, an archetypal quantum crystal with very strong anharmonicity.

description: A review is presented of the past 165 years of observation of the 4-day Cepheid Polaris, including the exciting results of the last 50 years, an interval that has produced three orbital solutions for the spectroscopic binary subsystem, recently resolved by HST, parameters for the optical companion, precise measurement of the star's trigonometric parallax and angular diameter, evidence for a rapid increase in its pulsation period, and observations of the dramatic decline and recent partial recovery of its light amplitude. There has been considerable discussion about the exact nature of the star, with potential resolutions summarized here. It is also noted that many of the star's characteristics are shared by a small number of other Cepheids that display rapid period increases identical to those predicted for stars in the first crossing of the instability strip, small light amplitudes, and intrinsic colors typical of variables lying near the center of the strip, where Cepheids of largest amplitude reside. While all members of the group appear to display the canonical traits of first crossers of the instability strip, Polaris has one unique peculiarity: a brief hiatus in its monotonic period increment between 1963 and 1966 during which the pulsation period underwent a dramatic decrease. Has the average brightness of the Cepheid also increased over the last millennium?

description: Linear and nonlinear optical lineshapes reveal details of excitonic structure in semiconductor polymers. We implement absorption, photoluminescence, and transient absorption spectroscopies in DPP-DTT, an electron push-pull copolymer, to explore the relationship between their spectral lineshapes and chain conformation, deduced from resonance Raman spectroscopy and from \textit{ab initio} calculations. The viscosity of precursor polymer solutions before film casting displays a transition that suggests gel formation above a critical concentration. Upon crossing this viscosity deflection concentration, the lineshape analysis of the absorption spectra within a photophysical aggregate model reveals a gradual increase in interchain excitonic coupling. We also observe a red-shifted and line-narrowed steady-state photoluminescence spectrum, along with increasing resonance Raman intensity in the stretching and torsional modes of the dithienothiphene unit, which suggests a longer exciton coherence length along the polymer-chain backbone. Furthermore, we observe a change of lineshape in the photoinduced absorption component of the transient absorption spectrum. The derivative-like lineshape may originate from two possibilities: a new excited-state absorption, or from optical Stark effect, both of which are consistent with the emergence of high-energy shoulder as seen in both photoluminescence and absorption spectra. Therefore, we conclude that the exciton is more dispersed along the polymer chain backbone with increasing concentrations, leading to the hypothesis that the polymer chain order is enhanced when the push-pull polymers are processed at higher concentrations. Thus, tuning the microscopic chain conformation by concentration would be another factor of interest when considering the polymer assembly pathways for pursuing large-area and high-performance organic optoelectronic devices.

description: Relativistic effects are investigated in nuclear matter calculations employing renormalized low-momentum nucleon-nucleon ($NN$) interactions. It is demonstrated that the relativistic effects cure a problem of non-relativistic low-momentum interactions, which fail to reproduce saturation of nuclear matter. Including relativistic effects, one already obtains saturation in a Hartree-Fock calculation. Brueckner-Hartree-Fock calculations lead to a further improvement of the saturation properties. The results are rather insensitive to the realistic $NN$ interaction on which they are based.

The Day of Archaeology project aimed to provide a window into the daily lives of archaeologists from all over the world. The project asked people working, studying or volunteering in the archaeological world to participate in a 'Day of Archaeology' each year by recording their day and sharing it through text, images or video on the Day of Archaeology blog.
The project asked anyone with a personal, professional or voluntary interest in archaeology to get involved, and help highlight the reasons why archaeology is vital to protect the past and inform our futures. The resulting Day of Archaeology project archive demonstrates the wide variety of work the archaeological profession undertakes day-to-day across the globe, and helps to raise public awareness of the relevance and importance of archaeology to the modern world.
The first ever Day of Archaeology was held in 2011 and, since then, the project had thousands of archaeologists take part in the event, from those working in the field through to specialists working in laboratories and behind computers. The last Day of Archaeology was on Friday 28th July 2017.

Land information systems and the policy process

description: There is a commonly held belief in the land information systems community that there is a strong causal link between the availability of reliable, consistent information and effective decision making processes; that the quality of this information bears directly on the quality of decision making and that the application of land information system based techniques to the policy process effecting the planning and management of land is superior, and somehow more proper than the normal social and political processes used to resolve such issues. These assumptions are questioned. The thesis suggests that there is little evidence to support these beliefs, that the benefits land information systems are delivering at the administrative and management levels are not extendable, except marginally, to the public decision making arena. It moves on to show that the structure and functionality of land information systems will need to be extensively modified and extended if these systems are to make a contribution to the policy process, as the land information system community believes it should. To defend this thesis, both land information systems and the policy and problem solving processes are examined from an information utilisation perspective. Firstly, the structure and operation of land information systems are reviewed in this light, as is the origin of the link between these systems and the planning and policy processes. Having established this nexus, the problem solving, decision making and public policy processes are examined for how formal, structured information of the type provided by land information system does, or could, interact with these processes. From this analysis, and the research findings from the knowledge utilisation field, it is concluded that land information systems will need to place its data into an extended contextual and value frameworks, introduce different data quality standards, and restructure its systems and functionality in a way that facilitates learning and understanding as opposed to decision making. How this may be achieved, and what role land information systems could reasonably expect to play in the policy process completes the thesis.

description: With the rise of cameras and smart sensors, humanity generates an exponential amount of data. This valuable information, including underrepresented cases like AI in medical settings, can fuel new deep-learning tools. However, data scientists must prioritize ensuring privacy for individuals in these untapped datasets, especially for images or videos with faces, which are prime targets for identification methods. Proposed solutions to de-identify such images often compromise non-identifying facial attributes relevant to downstream tasks. In this paper, we introduce Disguise, a novel algorithm that seamlessly de-identifies facial images while ensuring the usability of the modified data. Unlike previous approaches, our solution is firmly grounded in the domains of differential privacy and ensemble-learning research. Our method involves extracting and substituting depicted identities with synthetic ones, generated using variational mechanisms to maximize obfuscation and non-invertibility. Additionally, we leverage supervision from a mixture-of-experts to disentangle and preserve other utility attributes. We extensively evaluate our method using multiple datasets, demonstrating a higher de-identification rate and superior consistency compared to prior approaches in various downstream tasks.

Visible Stars as Apparent Observational Evidence in Favor of the Copernican Principle in the Early 17th Century

description: The Copernican Principle (which says the Earth and sun are not unique) should have observational consequences and thus be testable. Galileo Galilei thought he could measure the true angular diameters of stars with his telescope; according to him, stars visible to the naked eye range in diameter from a fraction of a second to several seconds of arc. He used this and the Copernican Principle assumption that stars are suns as a method of determining stellar distances. The expected numbers of naked eye stars brighter than a given magnitude can be calculated via Galileo's methods; the results are consistent with data obtained from counting naked eye stars. Thus the total number of stars visible to the naked eye as a function of magnitude would appear to Galileo to be data supporting the Copernican Principle.

Aspects of drug use in schizophrenia, cardiac surgery and palliative care
Creators: name: Young, Rachel Susan
Publisher: name: University Of Tasmania

description: The research in this thesis involved four studies of the variability in plasma concentrations and effects of a selection of drugs used in schizophrenia, cardiac surgery and palliative care. 1. Fluphenazine study Steady-state pre-dose plasma concentrations of fluphenazine were measured using a gas chromatography I mass spectrometry assay in 24 patients with schizophrenia who were receiving continuous treatment with depot intramuscular fluphenazine decanoate. Clinical response was measured using the Andreasen Scale for positive and negative symptoms. Poorer clinical control was related to higher log transformed plasma concentrations of fluphenazine and higher fluphenazine decanoate dosage. The log transformed plasma concentrations of fluphenazine and the fluphenazine decanoate dosages were weakly related. These results indicated the useful role that plasma level monitoring can fulfill in identifying patients who are therapy-resistant despite optimal or high plasma levels. 2. CPB study This study examined the effect of cardiopulmonary bypass (CPB) surgery on the total and unbound plasma concentrations of fentanyl and the total plasma concentrations of alcuronium in sixteen patients. Due to the large number of factors which may affect pharmacokinetics during CPB, the results were difficult to deal with mathematically. Despite marked declines in the plasma concentrations of both drugs on initiation of CPB, suitable plasma concentrations for anaesthesia were maintained throughout the procedure. 3. Subcutaneous fentanyl This study investigated the steady-state total and unbound plasma concentrations of fentanyl during continuous subcutaneous administration in 20 palliative care patients. Infusion rates and both total and unbound plasma concentrations of fentanyl were correlated. Even with standardisation for dosage, there was an 8-fold variation in total plasma concentrations and a 3.5-fold variation in unbound plasma concentrations of fentanyl. There was considerable inter-patient variability in the pharmacokinetics of fentanyl with subcutaneous infusion in the palliative care setting, which necessitated careful titration of dosage according to individual clinical response. 4. Nebulised morphine trial The final study involved a trial of nebulised morphine for dyspnoea in eleven palliative care patients. Due to patient attrition and the resulting small sample size, a significant improvement in respiratory function and assessment of dyspnoea could not be found overall. Individual patients, however, reported an improvement in their symptoms. More studies with increased numbers are needed to statistically prove the benefit of nebulised morphine over saline alone for the relief of dyspnoea.
