A mixed-methods investigation of attitudes to chronic obstructive pulmonary disease in general practice and the utility of spirometry for improving its recognition and management
Creators: name: Walters, JAE
Publisher: name: University Of Tasmania
Year: 2023

description: Chronic Obstructive Pulmonary Disease (COPD) is a major cause of disability and health care utilisation in Australia. The population prevalence is estimated at around 10% but up to 80% may be unrecognised. Lack of early diagnosis reduces the opportunity for better management. Clinical practice guidelines were developed in the 1990's to improve the diagnosis and management. The recommendation in the 2003 Australian COPDX guidelines for case finding in primary care using spirometry in high-risk subjects was based on limited evidence. A preliminary qualitative-quantitative study of the attitudes of patients with (recognised) COPD and their general practitioners (GPs) to the disease and its diagnosis identified operational and behavioural barriers to earlier diagnosis, especially lack of access and expertise in spirometry among GPs. A cluster randomised crossover study was conducted over twelve months in eight practices in Southern Tasmania offering spirometry to smokers and ex-smokers aged over 35 years. The study compared a model of opportunistic spirometry provision by visiting trained nurses (TN) with usual care (UC) where practices were provided with an electronic spirometer and spirometry training. Models were evaluated quantitatively for effectiveness, acceptability and utility in increasing the diagnosis of COPD, and qualitatively through focus groups with GPs. A longitudinal cohort of smokers was recruited in TN practices to assess the effect of feedback about normal or obstructive spirometry on smoking cessation and motivation to stop smoking using the Transtheoretical Model of stages. Spirometry provision in the TN model resulted in significantly more spirometry of high quality and testing in a greater proportion of the eligible population than the UC model. Although the TN model enabled recognition of substantial numbers of individuals with previously unrecognised obstruction, this did not translate into increased doctor-recorded diagnosis of COPD. Better practice systems for follow up, support for GPs in interpretation and realistic funding of spirometry are needed to achieve better outcomes from increased spirometry in primary care. Feedback to smokers with normal lung function was not associated with backward shift in stage of change but feedback on the presence of lung damage was associated forward shift in stage of change when allowing for smoking exposure. The odds of backward shift with feedback on lung damage, was related to pre-existing perceptions about poor lung health. Although spirometry is fundamental to making a diagnosis of COPD, provision through a model in primary care that delivers a high testing rate and high quality results will not increase diagnosis in the at-risk group without an effective protocol for appropriate action on results.
On Staggered Indecomposable Virasoro Modules

description: In this article, certain indecomposable Virasoro modules are studied. Specifically, the Virasoro mode L_0 is assumed to be non-diagonalisable, possessing Jordan blocks of rank two. Moreover, the module is further assumed to have a highest weight submodule, the "left module", and that the quotient by this submodule yields another highest weight module, the "right module". Such modules, which have been called staggered, have appeared repeatedly in the logarithmic conformal field theory literature, but their theory has not been explored in full generality. Here, such a theory is developed for the Virasoro algebra using rather elementary techniques. The focus centres on two different but related questions typically encountered in practical studies: How can one identify a given staggered module, and how can one demonstrate the existence of a proposed staggered module. The text is liberally peppered throughout with examples illustrating the general concepts. These have been carefully chosen for their physical relevance or for the novel features they exhibit.

Laboured Sexualities: The Experiences of Young Queer People in the Workplace
Creators: name: Willis, PB
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis is an investigation of how young people experience the workplace as queer (non-heterosexual) workers in the Australian labour market. Previous studies discuss the workplace as a problematic space for queer workers, depicting a site of discrimination, harassment and abuse on the grounds of sexuality. It can be argued that the workplace is configured as a sexual and gendered environment in which heterosexual expressions and relationships are frequently privileged over other sexual subjectivities. The voices of young people are predominantly absent from the literature examining queer sexualities in the workplace, despite their unique position as newcomers to the labour market. Thus, the aims of my research were to learn how young queer people experienced their place of paid employment in the Australian labour market and to examine how organisational dynamics affected their working lives. Addressing these aims through a constructivist methodology, I invited young queer people to share their accounts of former and current work environments. Thirty-four (34) young people aged 18 to 26 years participated through three qualitative methods: web-based surveys, online interviews and face-to-face interviews. The findings of this study show that young queer people experienced the workplace across five interdependent dimensions as: 1) sexually exclusive spaces; 2) regulatory spaces; 3) silencing spaces; 4) inclusive spaces; and 5) sexually diverse spaces. Across these dimensions, young people participated in both enabling and constraining environments. Negotiating constraining work environments constituted a secondary form of labour for young queer workers as they faced adverse challenges in sustaining supportive and safe work-relationships with other organisational participants. Conversely, working in enabling work environments brought opportunities to form supportive and validating relationships with other organisational participants. Within their accounts of the workplace, young queer people were positioned as victims of symbolic and material violence, as agents of change in resisting and refuting homonegative discourse, and as equal and valued employees. This thesis concludes that while working across the multidimensions of the workplace presents complex challenges for young queer workers, it also generates solutions for the development of inclusive work environments. Accordingly, the findings of this study hold implications for change in policy and practice in the field of workplace diversity, and for extending social work knowledge in the field of sexuality.

description: Gravity waves (GWs) are important for coupling the mesosphere to the lower atmosphere during sudden stratospheric warmings (SSWs). Here, a minor SSW is internally generated in a simulation with the upper-atmosphere configuration of the ICOsahedral Nonhydrostatic model. At a horizontal resolution of 20 km the simulation uses no GW drag parameterizations but resolves large fractions of the GW spectrum explicitly, including orographic and nonorographic sources. Consistent with previous studies, the simulated zonal-mean stratospheric warming is accompanied by zonal-mean mesospheric cooling. During the course of the SSW the mesospheric GW momentum flux (GWMF) turns from mainly westward to mainly eastward. Waves of large phase speed (40–80 m s -1) dominate the eastward GWMF during the peak phase of the warming. The GWMF is strongest along the polar night jet axis. Parameterizations of GWs usually assume straight upward propagation, but this assumption is often not satisfied. In the case studied here, a substantial amount of the GWMF is significantly displaced horizontally between the source region and the dissipation region, implying that the local impact of GWs on the mesosphere does not need to be above their local transmission through the stratosphere. The simulation produces significant vertically misaligned anomalies between the stratosphere and mesosphere. Observations by the Microwave Limb Sounder confirm the poleward tilt with height of the polar night jet and horizontal displacements between mesospheric cooling and stratospheric warming patterns. Thus, lateral GW propagation may be required to explain the middle-atmosphere temperature evolution in SSW events with significant zonally asymmetric anomalies. ©2019. The Authors.

description: This paper considers the relative frequencies of distinct types of individuals in multitype branching processes. We prove that the frequencies are asymptotically multivariate normal when the initial number of ancestors is large and the time of observation is fixed. The result is valid for any branching process with a finite number of types; the only assumption required is that of independent individual evolutions. The problem under consideration is motivated by applications in the area of cell biology. Specifically, the reported limiting results are of advantage in cell kinetics studies where the relative frequencies but not the absolute cell counts are accessible to measurement. Relevant statistical applications are discussed in the context of asymptotic maximum likelihood inference for multitype branching processes.

Black Hole Partition Function using Hybrid Formalism of Superstrings

description: The type IIA superstring partition function Z_IIA on the euclidean attractor geometry AdS_2 x S^2 x CY_3, computes the modified elliptic genus Z_BH of the associated black hole. The hybrid formalism of superstrings defined as a conformally invariant sigma model on the coset supermanifold PSU(1,1|2)/U(1)xU(1), together with Calabi-Yau and chiral boson CFTs, is used to calculate Z_IIA. The sigma model action on AdS_2 x S^2 is explicitly written in U(1)xU(1) invariant variables. The N=2 generators of AdS_2 x S^2 x CY_3 are enlarged and embedded in an N=4 topological algebra. The world sheet superconformal invariance is then used to construct a nilpotent BRST operator, in contrast to the kappa symmetry analysis used by Beasely et. al. in hep-th/0608021. The sigma model action is explicitly shown to be closed under this BRST operator. Localization arguments are then used to deform the world sheet path integral with the addition of a BRST exact term, where, contributions arise only from the center of AdS_2 and, the north and south poles of S^2. This leads to the OSV result Z_BH = Z_IIA = |Z_top|^2, where |Z_top|^2 is the square of the topological string partition function.

description: The Orca Seamount is a submarine volcanic structure, located in a tectonic area of the Bransfield Strait, characterized by cortical extension and roll back-type subduction. Recent investigations have described the presence of hydrothermal activity and thermophilic microorganisms in this submarine volcano, raising questions regarding the role these microorganisms might play in the environment. The presence of hydrothermal activity interacting with cold Antarctic marine waters has probably exerted a great impact on the chemistry of the Orca Seamount area, providing different types of substrates capable to support complex microbial communities. In this work, we further study the Orca Seamount area with respect to the mineralogy present in this environment and the role microorganisms might play in the biogeochemical cycles. Here we show that the assemblage of minerals detected in the Orca Seamount area is like those commonly found in other hydrothermal environments, consistent with previous investigations reporting hydrothermal activity in this zone. Sulfur- and iron-bearing minerals in addition to inorganic soluble compounds are able to support chemosynthetic microbial communities inhabiting the Orca Seamount. The role of these microorganisms on the sulfur, iron, and carbon cycle is discussed and analyzed in the context of the mineralogy and conditions of the environment.

description: Free traveling Rossby wave normal modes (RNMs) are often investigated through large-scale space-time spectral analyses, which therefore is subject to observational availability, especially in the mesosphere. Ground-based mesospheric observations were broadly used to identify RNMs mostly according to the periods of RNMs without resolving their horizontal scales. The current study diagnoses zonal wave numbers of RNM-like oscillations occurring in mesospheric winds observed by two meteor radars at about 79°N. We explore four winters comprising the major stratospheric sudden warming events (SSWs) 2009, 2010, and 2013. Diagnosed are predominant oscillations at the periods of 10 and 16 days lasting mostly for three to five whole cycles. All dominant oscillations are associated with westward zonal wave number m=1, excepting one 16-day oscillation associated with m=2. We discuss the m=1 oscillations as transient RNMs and the m=2 oscillation as a secondary wave of nonlinear interaction between an RNM and a stationary Rossby wave. All the oscillations occur around onsets of the three SSWs, suggesting associations between RNMs and SSWs. For comparison, we also explore the wind collected by a similar network at 54°N during 2012–2016. Explored is a manifestation of 5-day wave, namely, an oscillation at 5–7 days with m=1), around the onset of SSW 2013, supporting the associations between RNMs and SSWs. ©2020. The Authors.
Chirally enhanced corrections to FCNC processes in the generic MSSM

description: Chirally enhanced supersymmetric QCD corrections to FCNC processes are investigated in the framework of the MSSM with generic sources of flavor violation. These corrections arise from flavor-changing self-energy diagrams and can be absorbed into a finite renormalization of the squark-quark-gluino vertex. In this way enhanced two-loop and even three-loop diagrams can be efficiently included into a leading-order (LO) calculation. Our corrections substantially change the values of the parameters delta^{d,LL}_{23}, delta^{d,LR}_{23}, delta^{d,RL}_{23}, and delta^{d,RR}_{23} extracted from Br[B->X_s gamma] if tan(beta) is large. We find stronger (weaker) constraints compared to the LO result for negative (positive) values of mu. The constraints on delta^{d,LR,RL}_{13} and delta^{d,LR,RL}_{23} from B_d mixing and B_s mixing change drastically if the third-generation squark masses differ from those of the first two generations. K mixing is more strongly affected by the chirally enhanced loop diagrams and even sub-percent deviations from degenerate down and strange squark masses lead to profoundly stronger constraints on delta^{d,LR,RL}_{12}.

description: Sitting with crossed legs is a commonly adopted sitting posture in everyday situations. Yet, little is known about suitable design criteria to facilitate such a position inside a vehicle. This study is aimed at determining how much space is necessary for crossing the legs while considering legroom restrictions, anthropometric measures, and individual flexibility. More specifically, 3 D-kinematics of an ankle-on-knee leg-crossing task and the easiness to move ratings of 30 participants were assessed with restrictions of the legroom (2 heights × 3 distances) as well as without restrictions. Functional regression models revealed adaptations to a legroom restriction in the execution of movement, which occurred mainly in the knee joint and increased with more restricted legroom proportions. Therefore, the present study suggests a distance of 120% of the buttock–knee length between the dashboard and the occupant, as it requires only moderate adaptations and does not affect the perceived easiness of move. Practitioner Summary: This research investigated how much space is needed to cross the legs while sitting in a vehicle, finding that the movement execution is affected by legroom proportions, as well as individual anthropometry and flexibility. The study further presents the use of predicted motion traces to determine spatial requirements of movements. Abbreviations: BKL: buttock-knee length; H-point: hip point
A colonial palimpsest : Benjamin Duterrau's portrayals of Aboriginal people
Creators: name: Tritton, AE
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis argues for Benjamin Duterrau's merited place in Australian colonial art history. It examines Duterrau's depictions of Aborigines, both formally and contextually, seeking to reignite interest in Duterrau's work and its importance in contemporary society. On a more general level, it is concerned with visual European responses to Aborigines and how those responses may be read by a modern-day audience. Since the sale of Duterrau's work immediately following his death in 1851, there has been no solo exhibition of his work. His colonial depictions of Aboriginal people have largely been overlooked by scholars whose attention has instead turned to Thomas Bock and John Glover. In comparison, Duterrau's work is often considered artistically amateur and his recordings of people and events inaccurate. Instead I argue that his images are important historical texts that can add new dimensions to understanding colonial ideologies and European relations with Aborigines. While there has been no significant study dedicated to Duterrau's work, other than Stephen Scheding's The National Picture (2002) which is primarily concerned with the whereabouts of one of Duterrau's paintings, scholarly work focusing on Duterrau has tended to see his work in terms of colonial propaganda. From the limited writings on Duterrau, The Conciliation (1840), Duterrau's painting of George Augustus Robinson surrounded by Aborigines, has attracted the greatest interest as it is widely accepted as the first history painting in Australia. The significant status of The Conciliation has sparked debates over the historical accuracy of its depiction. For many writers its place in art history continues to be problematic. Duterrau's oil portraits of Aborigines are also bathed in controversy. This thesis will engage with the differing views and provide an analysis of how Duterrau's work may be valued in contemporary Australian society. In doing so it reveals the contingencies of reading an historical artwork and the complex, emotional investments in portraits of Aborigines.

description: Attempts to extend our previous work using the octonions to describe fundamental particles lead naturally to the consideration of a particular real, noncompact form of the exceptional Lie group E6, and of its subgroups. We are therefore led to a description of E6 in terms of 3x3 octonionic matrices, generalizing previous results in the 2x2 case. Our treatment naturally includes a description of several important subgroups of E6, notably G2, F4, and (the double cover of) SO(9,1), An interpretation of the actions of these groups on the squares of 3-component "Cayley spinors" is suggested.

The results obtained show that the decrease of the gap length to a few tens of micrometres for a given current density results in a progressive shrinking of the quasi-neutral bulk in the microplasma and its complete disappearance. The decrease of the gap length further leads to an increase of the discharge voltage and the electron temperature and to slightly less heating of the gas. © 2020 The Authors.

Studies of the effects of different treatments on the metabolizable energy value of wheat
Creators: name: El-Lakany, Safaa
Publisher: name: University of British Columbia
Year: 2011

description: Four successive experiments were carried out to study the effects of different treatments on the nutritive quality of 4 samples of wheat. The treatments used were autoclaving, freezing, water-soaking, acid-soaking, boiling in water, and combinations of these treatments. Metabolizable energy values of the various samples of treated and untreated wheat were determined using 2-3 weeks old chickens. Nitrogen retention from diets containing the different wheat samples was also measured. Autoclaving of wheat samples for 60 min. at 15 lb pressure markedly increased the nutritive quality of wheat as measured by metabolizable energy values. Freezing at -4°C for 5 days resulted in significant improvement in the metabolizable energy value of the samples of wheat treated in this manner. Water- or acid-soaking did not improve the metabolizable energy values of the wheat samples. The different treatments did not affect the percentage nitrogen retention from diets containing the treated wheat. Prolonged heating (autoclaving for 90 min. and 120 min. at 15 lb pressure) reduced the energy values of wheat as well as the percentage nitrogen retention.

Automated abundance analysis of underwater video using artificial intelligence techniques
Creators: name: Fearn, RC
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis discusses research into the various factors associated with the detection, classification and tracking of commercial scallops in underwater video (from a moving camera), for the purpose of computing abundance analysis statistics. Such statistics are sought by the Tasmanian Aquaculture and Fisheries Institute (TAFI) to support the sustainable management of Tasmanian commercial scallop fisheries. The use of video is preferable in terms of environmental impact to a traditional approach such as dredging, but the partially buried nature of the scallops makes the task very challenging. The research led to the development of a multi-stage video analysis system using a range of existing artificial intelligence techniques from the fields of computer vision and machine learning. The system comprises five main stages: instance detection, feature extraction, instance classification, motion estimation and temporal instance tracking. This system may be required to analyse many hours of video footage. Therefore we have explored many different computer-vision-related techniques and performed numerous comparisons on these techniques in an effort to maximise system throughput without compromising the overall accuracy achieved. This includes using the University of Southern California's iLab Neuromorphic Vision C++ Toolkit (iNVT) [iLab, 2010], during the initial stages of processing, to quickly reduce the overall search space of our system down to the analysis of conspicuous or salient regions within the footage. In addition to this we also investigated solutions that allow our system to skip frames during analysis. This decreases the overall processing time as fewer frames are presented to the system, but can also adversely affect the accuracy of motion estimation. To overcome this we then use a simple and efficient outlier detection method capable of smoothing inconsistencies within the data prior to predicting instance locations in future frames. The performance of each stage of our system has a direct impact on the performance of the remaining stages within the system. However of particular interest is the final stage which uses clustering to achieve temporal instance tracking, as it has become evident that this stage is not only capable of tracking instances through time but is also capable of performing a second round of classification based on cluster density that plays a vital role in the elimination of false positive instances introduced in earlier stages. As a result our system performs well, being robust enough to overcome significant inconsistencies within the existing video footage provided by TAFI.

description: It may be necessary to introduce new modes of communication between automated vehicles (AVs) and pedestrians. This research proposes using the AV’s lateral deviation within the lane to communicate if the AV will yield to the pedestrian. In an online experiment, animated video clips depicting an approaching AV were shown to participants. Each of 1104 participants viewed 28 videos twice in random order. The videos differed in deviation magnitude, deviation onset, turn indicator usage, and deviation-yielding mapping. Participants had to press and hold a key as long as they felt safe to cross, and report the perceived intuitiveness of the AV’s behaviour after each trial. The results showed that the AV moving towards the pedestrian to indicate yielding and away to indicate continuing driving was more effective than the opposite combination. Furthermore, the turn indicator was regarded as intuitive for signalling that the AV will yield. Practitioner Summary: Future automated vehicles (AVs) may have to communicate with vulnerable road users. Many researchers have explored explicit communication via text messages and led strips on the outside of the AV. The present study examines the viability of implicit communication via the lateral movement of the AV.

description: The effect of edge-type dislocation wall strain field on the Hall mobility in n-type epitaxial GaN was theoretically investigated through deformation potential within the relaxation time approach. It was found that this channel of scattering can play a considerable role in the low-temperature transport at the certain set of the model parameters. The low temperature experimental data were fitted by including this mechanism of scattering along with ionized impurities and charge dislocation ones.

description: We demonstrate that electrons in quantum dots defined by electrostatic gates in semiconductor nanotubes freeze orderly in space realizing a `Wigner molecule'. Our exact diagonalisation calculations uncover the features of the electron molecule, which may be accessed by tunneling spectroscopy -indeed some of them have already been observed by Deshpande and Bockrath [Nature Phys. 4, 314 (2008)]. We show that numerical results are satisfactorily reproduced by a simple ansatz vibrational wave function: electrons have localized wave functions, like nuclei in an ordinary molecule, whereas low-energy excitations are collective vibrations of electrons around their equilibrium positions.

description: We study the properties of sequences of the energy eigenvalues for some generalizations of q-deformed oscillators including the p,q-oscillator, the 3-, 4- and 5-parameter deformed oscillators given in the literature. It is shown that most of the considered models belong to the class of so-called Fibonacci oscillators for which any three consequtive energy levels satisfy the relation E_{n+1}=λE_n+ρE_{n-1} with real constants λ, ρ. On the other hand, for certain μ-oscillator known from 1993 we prove the fact of its non-Fibonacci nature. Possible generalizations of the three-term Fibonacci relation are discussed among which we choose, as most adequate for the μ$-oscillator, the so-called quasi-Fibonacci (or local Fibonacci) property of the energy levels. The property is encoded in the three-term quasi-Fibonacci (QF) relation with non-constant, n-dependent coefficients λand ρ. Various aspects of the QF relation are elaborated for the μ-oscillator and some of its extensions.

Modified gravity in Arnowitt-Deser-Misner formalism

description: Motivated by Horava-Lifshitz gravity theory, we propose and investigate two kinds of modified gravity theories, the f(R) kind and the K-essence kind, in the Arnowitt-Deser-Misner (ADM) formalism. The f(R) kind includes one ultraviolet (UV) term and one infrared (IR) term together with the Einstein-Hilbert action. We find that these two terms naturally present the ultraviolet and infrared modifications to the Friedmann equation. The UV and IR modifications can avoid the past Big-Bang singularity and the future Big-Rip singularity, respectively. Furthermore, the IR modification can naturally account for the current acceleration of the Universe. The Lagrangian of K-essence kind modified gravity is made up of the three dimensional Ricci scalar and an arbitrary function of the extrinsic curvature term. We find the cosmic acceleration can also be naturally interpreted without invoking any kind of dark energy. The static, spherically symmetry and vacuum solutions of both theories are Schwarzschild or Schwarzschild-de Sitter solution. Thus these modified gravity theories are viable for solar system tests.

Structural ageing and Australian crime trends : an exploration of the Easterlin hypothesis and the nature of the age-crime pattern

description: This thesis explores Richard Easterlin's theories regarding the association between structural ageing and crime, and its relation to the age-crime pattern, in a three-tiered analysis of Western Australian and South Australian apprehension trends. Easterlin (1987a) proposes two expressions of an age structure-crime pattern: cohort density and age composition. The cohort density expression suggests that, in comparison to smaller birth cohorts, large birth cohorts will engage in higher levels of criminal activity because they experience higher levels of internal competition, and thus, relative disadvantage. The age composition expression suggests a concomitant decline in young persons' share of the population age structure and crime because, in comparison to older persons, young persons make a more sizeable contribution to a population's crime levels. These arguments have not previously been investigated for Australia. Such analysis is appropriate, as official Australian crime statistics reflect the age-crime pattern (i.e. that individual offence levels peak around age 15-24 years and decline thereafter), and the population is ageing structurally. Initially, the state of the age-crime pattern is assessed through distribution and correlation analysis. The findings indicate that the Australian age-crime pattern is diminishing; a decline in young persons' share of all apprehensions, and an upward shift in the age distribution of offenders, is unfolding more or less simultaneously with change in population share. Cohort-specific departures from the age-crime pattern (i.e. whether or not the cohort has experienced declining apprehensions levels as it has aged, thus extending its participation in crime beyond the young crime-prone ages) are then identified by organising age-specific apprehension rates by birth cohort over time. Cohort analysis reveals that high cohort density is a potential source of variance in the age-crime pattern, and that departures from the age-crime pattern have been more sizeable (and frequent) for the younger, larger 'baby bust' cohorts (the residential Australian population born 1968-74). Finally, apprehension rates are standardised (and decomposed) for change in age structure, population size, and apprehension rates. These analyses show that structural ageing is constraining apprehension levels; its influence is generally greater than that of population growth, but lower than underlying change in apprehension levels which typically have the largest effect. Overall, therefore, the thesis finds Easterlin's propositions to be supported, with Australian crime trends having been influenced by both cohort density and age composition effects. However, there are some differences across gender, offence categories, and period, suggesting that, like the underlying age-crime pattern, the association between structural ageing and crime is not rigidly invariant.

description: A revolutionary avenue for vibrational imaging with super-multiplexing capability can be seen in the recent development of Raman-active bioortogonal tags or labels. These tags and isotopic labels represent groups of chemically inert and small modifications, which can be introduced to any biomolecule of interest and then supplied to single cells or entire organisms. Recent developments in the field of spontaneous Raman spectroscopy and stimulated Raman spectroscopy in combination with targeted imaging of biomolecules within living systems are the main focus of this review. After having introduced common strategies for bioorthogonal labeling, we present applications thereof for profiling of resistance patterns in bacterial cells, investigations of pharmaceutical drug-cell interactions in eukaryotic cells and cancer diagnosis in whole tissue samples. Ultimately, this approach proves to be a flexible and robust tool for in vivo imaging on several length scales and provides comparable information as fluorescence-based imaging without the need of bulky fluorescent tags. © 2020 The Authors.

Asymptotic solutions of a nonlinear diffusive equation in the framework of $κ$-generalized statistical mechanics

description: The asymptotic behavior of a nonlinear diffusive equation obtained in the framework of the $κ$-generalized statistical mechanics is studied. The analysis based on the classical Lie symmetry shows that the $κ$-Gaussian function is not a scale invariant solution of the generalized diffusive equation. Notwithstanding, several numerical simulations, with different initial conditions, show that the solutions asymptotically approach to the $κ$-Gaussian function. Simple argument based on a time-dependent transformation performed on the related $κ$-generalized Fokker-Planck equation, supports this conclusion.

Critical noncolorings of the 600-cell proving the Bell-Kochen-Specker theorem

description: Aravind and Lee-Elkin (1997) gave a proof of the Bell-Kochen-Specker theorem by showing that it is impossible to color the 60 directions from the center of a 600-cell to its vertices in a certain way. This paper refines that result by showing that the 60 directions contain many subsets of 36 and 30 directions that cannot be similarly colored, and so provide more economical demonstrations of the theorem. Further, these subsets are shown to be critical in the sense that deleting even a single direction from any of them causes the proof to fail. The critical sets of size 36 and 30 are shown to belong to orbits of 200 and 240 members, respectively, under the symmetries of the polytope. A comparison is made between these critical sets and other such sets in four dimensions, and the significance of these results is discussed.
