description: Digital micro-mirror devices (DMDs) have recently emerged as practical spatial light modulators (SLMs) for applications in photonics, primarily due to their modulation rates, which exceed by several orders of magnitude those of the already well-established nematic liquid crystal (LC)-based SLMs. This, however, comes at the expense of limited modulation depth and diffraction efficiency. Here we compare the beam-shaping fidelity of both technologies when applied to light control in complex environments, including an aberrated optical system, a highly scattering layer and a multimode optical fibre. We show that, despite their binary amplitude-only modulation, DMDs are capable of higher beam-shaping fidelity compared to LC-SLMs in all considered regimes.
Experiencing sustainable architecture : investigating a university's internal initiative for sustainability
Creators: name: Slatyer, PA
Publisher: name: University Of Tasmania

description: Climate change and the concomitant need to reduce greenhouse gas emissions through living sustainably is possibly the most significant issue of our time. Sustainable built environments have the potential to make a significant contribution to reducing greenhouse gas emissions. The success of sustainable architecture relies on both technology and its acceptance by building occupants. Whilst most research on sustainable architecture has focussed on technology, there has been less research on occupant experience of sustainable buildings. This research addresses this gap by investigating occupant experience of sustainable architecture through a case study and a review of literature relating to the phenomenological experience of architecture. The case study is the School of Architecture and Design at the University of Tasmania. The research design is based on mixed methodology, using questionnaire surveys to provide extensive quantitative data which is investigated more intensively through the qualitative research methods of interviews and focus groups. The results show strong dissatisfaction with most of the specific variables of comfort (temperature, air, noise, lighting, personal control), satisfaction with overall comfort, health and productivity and strong satisfaction with overall design aspects. This finding is consistent with the literature on comfort and occupant experience of green buildings. It appears that occupants in the case study building are adapting to the discomfort they experience, with the satisfaction they express for overall comfort and the building overall indicating tolerance and forgiveness of this discomfort. The analysis and discussion is structured thematically around the themes of comfort, delight and forgiveness, as these arose as the main issues from the data and have significance for the development of sustainable architecture. The internal environments of sustainable buildings are often more variable, less predictable and have a greater temperature range than air conditioned buildings, due to the use of passive technologies for heating, cooling and ventilation which more closely follow the external climate. Forgiveness of these less‚ÄövÑv™than‚ÄövÑv™static conditions is a positive step in the acceptance of sustainable architecture and can bring the benefit of thermal delight. The literature indicates that good design which encourages delight can have a positive effect on occupant well‚ÄövÑv™being which in turn may facilitate forgiveness. A phenomenological understanding of occupant experience supports the concept of comfort as a multi‚ÄövÑv™dimensional relationship between occupant and building. For centuries architects have been guided by the Vitruvian triad of Firmness, Commodity and Delight in their pursuit of architectural excellence. I propose that this is augmented by the triad of Forgiveness, Comfort and Delight to guide architects towards creating sustainable architecture for the twenty first century.

description: We review the status of CPT violation in the neutrino sector. Apart from LSND, current data favors three flavors of light stable neutrinos and antineutrinos, with both halves of the spectrum having one smaller mass splitting and one larger mass splitting. Oscillation data for the smaller splitting is consistent with CPT. For the larger splitting, current data favor an antineutrino mass-squared splitting that is an order of magnitude larger than the corresponding neutrino splitting, with the corresponding mixing angle less-than-maximal. This CPT-violating spectrum is driven by recent results from MINOS, but is consistent with other experiments if we ignore LSND. We describe an analysis technique which, together with MINOS running optimized for muon antineutrinos, should be able to conclusively confirm the CPT-violating spectrum proposed here, with as little as three times the current data set. If confirmed, the CPT-violating neutrino mass-squared difference would be an order of magnitude less than the current most-stringent upper bound on CPT violation for quarks and charged leptons.

Church of England in Tasmania under Bishop Montgomery, 1889-1901
Creators: name: Hart, Philip R
Publisher: name: University Of Tasmania
Year: 2023

description: The Episcopate of Henry Hutchinson Montgomery, fourth Bishop of Tasmania, was a period of unparalleled expansion for the Church of England, This was directly due to Montgomery's infectious enthusiasm, and flair for organization. Though helped by a few valuable assistants, notable Archdeacon F.T. Whitington, the high percentage of inadequate clergy and the mass of lethargic laity prevented the Bishop achieving all he desired. In every field, only some of the plans were fulfilled. Montgomery inherited many incompetent priests, and these were a great handicap to parochial development. However, by dismissing those he could, and being very careful in the choice of new clergy, he managed to raise the standard of his clerical staff considerably. Another hindrance to advancement was the lack of lay support; a few stalwarts helped, but all Montgomery's efforts to encourage the laity in general to participate actively in the work of the Church failed. However, special efforts from his best clergy, with his encouragement, led to the Church spreading effectively, and for the first time, to the East, North-West, and West Coasts of Tasmania. A unique attempt was made by Montgomery personally on Cape Barren Island with the half-castes; representing both Church and State, he was principally responsible for the considerable endeavours made to improve all aspects of their existence. These efforts largely failed, due to the nature of the half-castes. For a similar reason, as well as the apathy of the average churchman, an attempt to Christianize the Chinese miners in Tasmania failed abysmally. More general missions, to create enthusiasm in the ordinary church-goer, had some temporary effect, but one, that of the Rev. George Grubb, brought the Church into disrepute through his naive emotionalism.

description: Let $k$ and $n$ be positive integers. Define $R(n,k)$ to be the minimum positive value of $$ | e_i \sqrt{s_1} + e_2 \sqrt{s_2} + ... + e_k \sqrt{s_k} -t | $$ where $ s_1, s_2, ..., s_k$ are positive integers no larger than $n$, $t$ is an integer and $e_i\in \{1,0, -1\}$ for all $1\leq i\leq k$. It is important in computational geometry to determine a good lower and upper bound of $ R(n,k)$. In this paper we show that this problem is closely related to the shortest vector problem in certain integral lattices and present an algorithm to find lower bounds based on lattice reduction algorithms. Although we can only prove an exponential time upper bound for the algorithm, it is efficient for large $k$ when an exhaustive search for the minimum value is clearly infeasible. It produces lower bounds much better than the root separation technique does. Based on numerical data, we formulate a conjecture on the length of the shortest nonzero vector in the lattice, whose validation implies that our algorithm runs in polynomial time and the problem of comparing two sums of square roots of small integers can be solved in polynomial time. As a side result, we obtain constructive upper bounds for $R(n,k)$ when $ n$ is much smaller than $2^{2k}$.

description: Radical Cystectomy (RC) is the treatment of choice in muscle invasive urinary bladder cancer (MIBC). However; it carries a high-risk for morbidity and mortality, prolonged length of stay (LOS), and an increase in hospital readmission (RA) rates when compared with other urologic surgical procedures. In an effort to mitigate the morbidity associated with RC, the Enhanced Recovery after Surgery (ERAS) pathway was developed. This clinical pathway guides multi-disciplinary teams in their efforts to improve recovery from RC. The purpose of this Doctor of Nursing (DNP) project was to update the ERAS pathway to include current clinical practice guidelines and improve communication and documentation related to completion of the ERAS pathway. The measured outcomes included: 1) length of stay (LOS) in days, 2) RA within 30 days, 3) patient satisfaction, 4) return of bowel function in relation to decreased incidence of post-op ileus, and 5) incidence of DVT. During the implementation and post-intervention period, there was a reduction in 30-day RA rates, LOS, complications, increases in patient satisfaction and a shorter return of bowel activity post-RC. There were improvements in documentation practices and communication between interdisciplinary team (IDT) members related to the completion of the ERAS pathway. This project was able to develop and rejuvenate a culture of improvement and compliance among IDT members involved in the care of post-RC patients.

description: We use two simulations performed within the Constrained Local UniversE Simulation (CLUES) project to study both the shape and radial alignment of (the dark matter component of) subhaloes; one of the simulations is a dark matter only model while the other run includes all the relevant gas physics and star formation recipes. We find that the involvement of gas physics does not have a statistically significant effect on either property -- at least not for the most massive subhaloes considered in this study. However, we observe in both simulations including and excluding gasdynamics a (pronounced) evolution of the dark matter shapes of subhaloes as well as of the radial alignment signal since infall time. Further, this evolution is different when positioned in the central and outer regions of the host halo today; while subhaloes tend to become more aspherical in the central 50% of their host's virial radius, the radial alignment weakens in the central regime while strengthening in the outer parts. We confirm that this is due to tidal torquing and the fact that subhaloes at pericentre move too fast for the alignment signal to respond.

description: The INT Photometric H-Alpha Survey (IPHAS) is particular effective in tracing asymptotic giant branch (AGB) stars across the Galactic disk due to its use of broad-band r' and i' filters, and the clear separation of the dwarf and giant branches in the colour-colour diagram. Here we discuss some results from our studies of the Galactic AGB population that has been revealed by IPHAS. This includes a photometric study, our spectroscopic follow-up campaign, and the photometric technique that allows us to separate O-rich, S-type and carbon stars across the entire Galactic disk based on their IPHAS photometry alone. We also discuss the potential impact of this technique on our understanding of the dredge-up process in AGB stars, Galactic chemical evolution, and the structure and properties of the Galactic disk.

An investigation of tree decline on Tasmanian farms
Creators: name: McMurray, SK
Publisher: name: University Of Tasmania
Year: 2023

description: Little attention has been given to the death and decline of remaining native trees on Tasmanian farms. This phenomenon is prevalent in the pastoral Midland region of the state and, so far, is unstudied. The present study, as an exploratory investigation, seeks to ascertain certain characteristics of this loss of farm trees. The rate of loss of scattered, native trees on 14 grazing properties was estimated from tree counts of aerial photographs, separated by a period of 32 years. A mean rate of 54 per cent was found for this period. This considerably exceeds estimated rates of tree decline found in similar studies in mainland states. Factors associated with tree decline were also investigated. Photographic interpretation and landholder interviews enabled areas within properties to be classified according to pasture type and associated management practices. Tree count data from these areas showed an increasing rate of tree decline appeared to be associated with increasing intensity of land management. Biological and physico-chemical factors potentially associated with tree decline were assessed through landholder interviews. Drouqht emerged as an important non-lethal incitant in farm tree decline, althouqh other biophysical factors were not widely implicated in causal or predisposing capacities. In this respect, neither severe insect defoliation nor excessive soil salinity, important in tree decline elsewhere, is apparent in the Midlands. Tree decline in the region appears largely to be a land-use related phenomenon. The finding that there has been a high rate of loss of remaining farm trees in the region is seen as timely. It coincides with initial efforts by governmcnt to encouraqe replacement of trees on farms. These efforts are in need of considerable expansion. Land-holders, generally, did not recognize tree decline and efforts are also required to raise awareness to the existence of, and problems associated with, such a hiqh rate of tree loss.

description: Given a manifold M with an action of a quadratic Lie algebra d, such that all stabilizer algebras are co-isotropic in d, we show that the product M\times d becomes a Courant algebroid over M. If the bilinear form on d is split, the choice of transverse Lagrangian subspaces g_1, g_2 of d defines a bivector field on M, which is Poisson if (d,g_1,g_2) is a Manin triple. In this way, we recover the Poisson structures of Lu-Yakimov, and in particular the Evens-Lu Poisson structures on the variety of Lagrangian Grassmannians and on the de Concini-Procesi compactifications. Various Poisson maps between such examples are interpreted in terms of the behaviour of Lagrangian splittings under Courant morphisms.

Some effects of host tree nutrition on establishment and survival of the balsam woolly aphid, Adelges picease (Ratz)
Creators: name: Carrow, Justin Roderick
Publisher: name: University of British Columbia
Year: 2011

description: A greenhouse study was undertaken to investigate some relationships between nutrition of the host tree, Abies amabilis, as influenced by soil fertility and nitrogen fertilizers, and biology of the balsam woolly aphid, Adelges piceae (Ratz.). Seedlings were reared in two soil regimes - nutrient-deficient mineral soil and enriched humic soil. All trees were infested with aphid larvae, and observations made to determine the influence of soil fertility on the establishment rate of larvae on host trees. Subsequently, groups of 10 trees were treated with foliar nutrients, using ammonium nitrate and urea in various concentrations. The establishment rate of larvae on humic soil host trees was 2.5 times greater than on mineral soil trees. In addition, growth rate of the aphid population on humic soil trees was 37% greater than on mineral soil trees over a four week period. Soil fertility also influenced the life history of the insect. One foliar nutrient adversely affected the aphid population. Over a 10 week period, the aphid population on trees treated with 1% ammonium nitrate decreased by 23%, whereas the control population Increased 30.9%. It is postulated that this foliar treatment manifests its adverse effect primarily by inhibiting initial settling of larvae on the host trees. This inhibition may be related to fertilizer-induced alterations in the amino acid composition of feeding tissue.
Finding the Most Vital Edges for Shortest Paths: Algorithms and Complexity for Special Graph Classes
Creators: name: Stahlberg, Maximilian
Publisher: name: Zenodo
Year: 2016

description: We study the NP-hard problem of finding the most vital edges for shortest paths between two terminals of an undirected graph, that are a small number of edges whose deletion increases the distance between the terminals significantly. The associated decision problem asks whether a given edge deletion budget is sufficient to achieve the desired length increase. We study this decision problem as well as three variants, where edges are assigned a length or a deletion cost or both, in the context of selected graph classes. We show that the problem remains NP-complete on all superclasses of complete graphs when either edge weight is non-uniform. In the case where both are uniform, we give linear-time decision algorithms for complete and threshold graphs and conjecture the correctness of a polynomial-time algorithm that decides the problem on proper interval graphs. We also look into multigraphs and provide two FPT algorithms for the two-terminal series-parallel graphs that have polynomial running time if at least one of the edge weights is uniform.

description: The today's energy density of the induced (second order) gravitational wave background in the frequency region $\sim 10^{-3} - 10^3$ Hz is constrained using the existing limits on primordial black hole production in the early Universe. It is shown, in particular, that at frequencies near $\sim 40$ Hz (which is the region explored by LIGO detector), the value of the induced part of $Ω_{GW}$ cannot exceed $(1-3)\times 10^{-7}$. The spread of values of the bound is caused by the uncertainty in parameters of the gravitational collapse of black holes.

Evaluation of current land subdivision practice using the objective of sustainable development as the criteria
Creators: name: Quinn, R
Publisher: name: University Of Tasmania
Year: 2023

description: The current land subdivision practice in Tasmania is not meeting the objective of sustainable development. Although Tasmania has an example of world1s best practice planning legislation there are no links between the objective of sustainable development and the decision making process in regard to land subdivision. A link between the objective of sustainable development and the actual planning schemes which govern how land is used is required. A greater emphasis on how land is used instead of what land is used for is needed. Performance based planning schemes are moving towards addressing the requirements of how developments occur. The legislative process is fundamental in controlling the outcome of subdivision in order to meet the sustainable development objective. The outcome of a subdivision is dependent on how the land is ultimately used. The process needs to be outcome focussed as many of the consequences of land subdivision are practically impossible to reverse, particularly in the case of the natural environment. It is apparent that once the subdivision has been approved it too late to retro-fit sustainable development principles. The decision needs to be made at a early stage; can or should this parcel of land be subdivided at all? The project has shown that there is a over supply of subdivided land suitable for residential development which clearly does not meet the sustainable development objective of the Land Use Planning and Approvals Act 1993 (LUPAA). The reasons for this situation have been given, along with a historical perspective on the current situation to better understand the issues involved. This historical perspective also gives an understanding of what is possible and how circumstances may be changed. Clearly, urgent action needs to be taken to prevent the oversupply of land and subsequent degradation of the environment. The issue of intergenerational equity is an issue of concern which has not been addressed or in many cases considered. This issue is of increasing concern as time passes and present legislation does not consider the impact of present decisions on future generations.

description: We determine upper limits on the dark matter (DM) self-annihilation cross section for scenarios in which annihilation leads to the production of electron--positron pairs. In the Galactic centre (GC), relativistic electrons and positrons produce a radio flux via synchroton emission, and a gamma ray flux via bremsstrahlung and inverse Compton scattering. On the basis of archival, interferometric and single-dish radio data, we have determined the radio spectrum of an elliptical region around the Galactic centre of extent 3 degrees semi-major axis (along the Galactic plane) and 1 degree semi-minor axis and a second, rectangular region, also centered on the GC, of extent 1.6 degrees x 0.6 degrees. The radio spectra of both regions are non-thermal over the range of frequencies for which we have data: 74 MHz -- 10 GHz. We also consider gamma-ray data covering the same region from the EGRET instrument (about GeV) and from HESS (around TeV). We show how the combination of these data can be used to place robust constraints on DM annihilation scenarios, in a way which is relatively insensitive to assumptions about the magnetic field amplitude in this region. Our results are approximately an order of magnitude more constraining than existing Galactic centre radio and gamma ray limits. For a DM mass of m_χ=10 GeV, and an NFW profile, we find that the velocity-averaged cross-section must be less than a few times 10^-25 cm^3 s^-1.

PRACTICE GUIDELINES FOR THE CARE OF PATIENTS UNDERGOING MANDIBULAR DISTRACTION OSTEOGENESIS
Creators: name: Clarke, Noreen Catherine
Publisher: name: Zenodo
Year: 2018

description: Background The purpose of this project was to develop evidence-based multidisciplinary clinical practice guidelines to direct the post-operative care of children with Robin sequence (RS) who undergo mandibular distraction osteogenesis (MDO). The care of the patient with RS who undergoes MDO is a very complex process, and one that requires multiple disciplines and pediatric subspecialists. The goal of this project was to use evidence-based strategies and expert opinion (where evidence was not available) to improve the clinical care of this complex population of children who have RS. The Iowa Model provided the necessary structure to develop the RS practice guidelines. Methods This project took place at a private, non-profit tertiary children’s hospital located in an urban area of Los Angeles. This hospital subscribes to the concept of familycentered care. Children with RS requiring MDO receive care in the newborn and infant critical care unit (NICCU) and pediatric intensive care unit (PICU). The guidelines were developed for children with RS younger than 6 months with airway obstruction caused by micrognathia. Approximately twelve to fifteen patients with RS undergo MDO yearly at this institution. The stakeholders for this project included a multidisciplinary team of providers and the families of patients undergoing MDO. Results The successful post-operative management of complex patients requires clear guidelines. In developing practice guidelines that mitigate variability in care, it was essential to involve the entire multidisciplinary team. Nursing has an opportunity to participate in the development of multidisciplinary practice guidelines to insure comprehensive care. The resulting clinical practice guidelines are comprehensive and inclusive of all stakeholders. Stakeholders have approved the proposed guidelines and they are now ready for piloting. Discussion/Conclusion It is projected that utilizing evidence-based interdisciplinary clinical practice guidelines to direct the post-operative care of children with RS who undergo MDO will significantly improve the quality and care coordination of these complex children. The next steps will be to pilot the guidelines on two to three infants. Feedback from all of the key stakeholders will be critical during this stage, as having their support will help ensure that these proposed guidelines become the new standard of care for the RS population. Once in place, an ongoing evaluation of this new standard of practice will be part of the plan, as well as the dissemination of our results on a national and international level.

The fine-tuning of the Universe: A philosophical analysis
Creators: name: Wood, Graham

description: This thesis is a philosophical examination of the fine-tuning of the Universe. It is in two parts, the first part examines the apparent improbability of the fine-tuning and the second examines responses to that apparent improbability. I begin part one by examining the physical theories that have generated the fine-tuning debate. I argue the debate presupposes a realist interpretation of numbers, scientific theory and laws of nature. Without these presuppositions the concepts of slightly different laws and initial conditions of the Universe should be interpreted as mathematical artifacts. I then go on to analyse the possibility space of universes. Physical possibility is excluded and logical possibility is unsatisfactory, so I introduce ontic possibility space to examine the possibility of other universes. I consider the evidence that slightly different universes are not life-allowing, and I suggest two theories that could explain this evidence. Ontic possibility space may be chaotic such that 'neighbouring' universes are substantially different in structure from our own. Alternatively ontic possibility space may be quantised such that slightly different universes are not ontically possible. I then consider the claim that this fine-tuned universe is improbable. I analyse the role of probability in the debate and use partitions of the probability space to examine the fine-tuning. I conclude that the fine-tuning can be considered improbable only if it is taken to be objectively significant. Without this the fine-tuning is isoprobable, meaning that it is as probable as any other outcome. In part two I consider the responses to the improbability. Two responses are attempts to explain away the improbability, either by postulating many universes or God. I also consider the possibility that this universe is the isolated result of an indeterministic ontic process. I examine the role of probability in explanation, focusing on the impact of indeterminism on this process. Often explanations are favoured that raise the probability of events. However I show that this can lead to error when considering isolated events in indeterministic systems. To avoid this error I apply the conformity maxim- explanations should generate epistemic probabilities that match ontic probabilities. I then go on to consider what triggers the need for explanation including an analysis of surprising and specified events. In considering the explanations of the fine-tuning, I analyse the multiple universe and design explanations. I conclude that the best response to the finetuning is to consider the universe as an isolated outcome of an indeterministic ontic process, possibly grounded in chaos or quantum theory.

description: The efficiency of energy transfer in ultrafast electronic relaxation of molecules depends strongly on the complex interplay between electronic and nuclear motion. In this study we use wavelength-selected XUV pulses to induce relaxation dynamics of highly excited cationic states of naphthalene. Surprisingly, the observed relaxation lifetimes increase with the cationic excitation energy. We propose that this is a manifestation of a quantum mechanical population trapping that leads to delayed relaxation of molecules in the regions with a high density of excited states. © 2019 Published under licence by IOP Publishing Ltd.

description: Two-dimensional manganese oxide layers have been grown on Pd(100) and have been characterized by scanning tunnelling microscopy (STM), low-energy electron diffraction (LEED) and X-ray photoelectron spectroscopy (XPS). The complex surface phase diagram of MnOx on Pd(100) is reported, where nine different novel Mn oxide phases have been detected as a function of the chemical potential of oxygen mO. Three regions of the chemical potential of oxygen can be identified, in which structurally related oxide phases are formed, often in coexistence at the surface. The different regions of mO are reflected in the oxidation states of the respective Mn oxide nanolayers as revealed by the Mn 2p and O 1s XPS binding energies. The MnOx nanolayers form two-dimensional wetting layers and it is speculated that they mediate the epitaxial growth of MnO on Pd(100) by providing structurally graded interfaces.

description: We consider the unitarity of the S-matrix for linearized General Relativity coupled to particle physics models. Taking renormalization group effects of the Planck mass into account, we find that the scale at which unitarity is violated is strongly dependent on the particle content of the theory. We find that the requirement that the S-matrix be unitary up to the scale at which quantum gravitational effects become strong implies a bound on the particle content of the model.

description: The two-point angular correlation function is a traditional method used to search for deviations from expectations of isotropy. In this paper we develop and explore a statistically descriptive three-point method with the intended application being the search for deviations from isotropy in the highest energy cosmic rays. We compare the sensitivity of a two-point method and a "shape-strength" method for a variety of Monte-Carlo simulated anisotropic signals. Studies are done with anisotropic source signals diluted by an isotropic background. Type I and II errors for rejecting the hypothesis of isotropic cosmic ray arrival directions are evaluated for four different event sample sizes: 27, 40, 60 and 80 events, consistent with near term data expectations from the Pierre Auger Observatory. In all cases the ability to reject the isotropic hypothesis improves with event size and with the fraction of anisotropic signal. While ~40 event data sets should be sufficient for reliable identification of anisotropy in cases of rather extreme (highly anisotropic) data, much larger data sets are suggested for reliable identification of more subtle anisotropies. The shape-strength method consistently performs better than the two point method and can be easily adapted to an arbitrary experimental exposure on the celestial sphere.

The enzymatic hydrolysis of ribonucleoside 2', 3'-cyclic phospates by a diesterase in nerve tissue
Creators: name: Lee, Jack Foo

description: During the past 50 years, a number of nucleophosphodiesterases have been studied. Of recent interest, is a brain phosphodiesterase which converts ribonucleoside 2',3'-cyclic phosphates to the corresponding ribonucleoside 2'-phosphates. The physiological role of this enzyme is entirely unknown. The present studies were designed to learn something of its intracellular distribution, properties and mechanism of action. The assay of the enzyme was based on the hydrolysis of adenosine 2', 3'-cyclic phosphate by the diesterase followed by the hydrolysis of the reaction product with alkaline phosphatase and subsequent analysis for inorganic phosphate by a modified method of Fiske and SubbaRow. Rabbit brain homogenate was fractionated into nuclear, mitochondrial, microsomal and 100,000 x g supernatant fluid fractions by differential centrifugation. 2',3'-Cyclic phosphodiesterase activity was found in all the fractions with the greatest activity in the mitochondrial fraction. Since the mitochondrial fraction was a heterogenous mixture as revealed by electron microscopy, its components were separated by sucrose density gradient centrifugation by established methods. Five subtractions were obtained (A, B, C, D, E). The lightest subfraction (A) contained most of the diesterase activity and electron microscopy revealed that this subfraction consisted of fragments of myelin of various sizes. The microsomal and nuclear fractions were also subjected to sucrose density gradient centrifugation. Again, the least dense, myelin-containing sub-fraction, contained most of the diesterase activity. It was also found that rabbit brain white matter contained greater diesterase activity than grey matter. The data provide strong evidence that the diesterase is associated with myelin. It was found that acetone extraction of the myelin fraction from a homogenate of white matter of beef brain resulted in a doubling of diesterase activity with a five-fold purification. Efforts directed toward solubilization of the enzyme were unsuccessful. Some properties of the enzyme were also determined. The diesterase opened the cyclic diester bond of cyclic-ended oligonucleotides, at least as large as (A₈) and did so, without cleavage of internucleotide bonds. It was inactivated by the sulfhydryl reagent, para-hydroxymercuribenzoate, and was unaffected by the presence of a wide variety of purine and pyrimidine compounds or derivatives and various nucleoside mono-, di- and triphosphates. The Km of the diesterase was determined to be 1.9 x 10⁻³ M.

description: Observing how long a dynamical system takes to return to some state is one of the most simple ways to model and quantify its dynamics from data series. This work proposes two formulas to estimate the KS entropy and a lower bound of it, a sort of Shannon's entropy per unit of time, from the recurrence times of chaotic systems. One formula provides the KS entropy and is more theoretically oriented since one has to measure also the low probable very long returns. The other provides a lower bound for the KS entropy and is more experimentally oriented since one has to measure only the high probable short returns. These formulas are a consequence of the fact that the series of returns do contain the same information of the trajectory that generated it. That suggests that recurrence times might be valuable when making models of complex systems.
