Development of an oral phosphocitrate prodrug to control calcinosis
Creators: name: Parry, Nathan Frank Glynn
Publisher: name: University Of Tasmania
Year: 2023

description: Phosphocitrate (PC) has previously demonstrated inhibitory potential against calcium crystallite formation associated with disease states such as urolithiasis, atherosclerosis and joint crystal deposition. The compound has proven active when injected intraperitoneally (ip) and intramuscularly. However, when administered orally, it has limited bioavailability. The present study has investigated synthesis of an oral PC prodrug and, in conjunction with determining the metabolic fate of the parent compound, assessed in viva inhibitory activity of the new PC derivative. Basic pharmacokinetics of PC were determined by a single intravenous (iv) injection Uugular vein) of radiolabelled PC followed by measurement within 60 min of the compound in plasma, urine and selected tissues. The plasma concentration-time profile of the compound followed a two-compartment model, with an elimination half-life of 30 min. Uptake of the administered dose accounted for less than 0.1 % in tissues, with 10 % in urine within 1 h. A capillary electrophoretic system was optimised for PC identification and measurement in urine. Longer-term studies involving iv (caudal vein) and ip administrations of non-labelled PC indicated total excretion of compound occurred within 12 hand 24 h, respectively. A synthetic strategy was developed for generating a methylacyloxy derivative of PC. The mono-sodium PC salt was reacted with chloromethylacetate under alkali conditions, with formamide as the solvent. Partial characterisation of the isolated product indicated that the PC derivative was water soluble, suggesting that it may not have been fully esterified, although phosphate esterification did occur as indicated by thin-layer chromatography. As anticipated, the derivative proved unable to prevent in vitro the transformation of amorphous calcium phosphate to hydroxyapatite. Orally administered prodrug inhibited chemically-induced subcutaneous plaques in rats with a similar potency to that of equimolar doses of ip administered parent compound. Similar urinary excretion patterns of the parent compound were observed whether PC was given orally as PC prodrug or ip as the parent compound. Enzymatic studies in vitro demonstrated slow hydrolysis of prodrug to parent compound in the presence of plasma with a more rapid hydrolysis noted using a rat liver homogenate. For the first time, it has been demonstrated that PC exhibits improved bioavailability when administered as an oral prodrug derivative, thus offering an alternate route of administration for its future consideration as a therapeutic drug against calcinosis.

Supplementary Text, Figures and Tables from Quantifying the relationship between within-host dynamics and transmission for viral diseases of livestock

description: Understanding the population dynamics of an infectious disease requires linking within-host dynamics and between-host transmission in a quantitative manner, but this is seldom done in practice. Here a simple phenomenological model for viral dynamics within a host is linked to between-host transmission by assuming that the probability of transmission is related to log viral titre. Data from transmission experiments for two viral diseases of livestock, foot-and-mouth disease virus in cattle and swine influenza virus in pigs, are used to parametrize the model and, importantly, test the underlying assumptions. The model allows the relationship between within-host parameters and transmission to be determined explicitly through their influence on the reproduction number and generation time. Furthermore, these critical within-host parameters (time and level of peak titre, viral growth and clearance rates) can be computed from more complex within-host models, raising the possibility of assessing the impact of within-host processes on between-host transmission in a more detailed quantitative manner.

description: Reported observations in H-alpha, Ca II H and K or or other chromospheric lines of coronal rain trace back to the days of the Skylab mission. Offering a high contrast in intensity with respect to the background (either bright in emission if observed at the limb, or dark in absorption if observed on disk) these cool blobs are often observed falling down from high coronal heights above active regions. A physical explanation for this spectacular phenomenon has been put forward thanks to numerical simulations of loops with footpoint concentrated heating, a heating scenario in which cool condensations naturally form in the corona. This effect has been termed 'catastrophic cooling' and is the predominant explanation for coronal rain. In this work we further investigate the link between this phenomenon and the heating mechanisms acting in the corona. We start by analyzing observations of coronal rain at the limb in the Ca II H line performed by the SOT instrument on board of the Hinode satellite. We then compare the observations with 1.5-dimensional MHD simulations of loops being heated by small-scale discrete events concentrated towards the footpoints (that could come, for instance, from magnetic reconnection events), and by Alfven waves generated at the photosphere. It is found that if a loop is heated predominantly from Alfven waves coronal rain is inhibited due to the characteristic uniform heating they produce. Hence coronal rain may not only point to the spatial distribution of the heating in coronal loops but also to the agent of the heating itself. We thus propose coronal rain as a marker for coronal heating mechanisms.

title: Social Interaction: The Relationship Between Facial Attractiveness and Verbal Influence Style
Creators: name: Lee, Laurie Jean
Publisher: name: Utah State University
Year: 1983

description: The purpose of this study was to determine if male and female communicators utilize different styles of persuasion with an attractive versus an unattractive female target. Forty undergraduate students were asked to persuade a female confederate in either an attractive condition or an unattractive condition to eat M&M's. Perceptions of attractiveness and personality assessments were checked by a post-experimental questionnaire. Influence attempts were rated and categorized by the use of the Social Interaction Scoring System. Individual responses were then factor analyzed to identify profiles of persuasive communication. These behavioral profiles were then statistically compared across experimental conditions by analyses of variance.
No significant differences were found for sex or experimental condition. The subjects did, however, perceive the confederate as significantly more attractive when in the attractive condition than when in the unattractive condition. Further, while the confederate was perceived as more curious and perceptive when in the attractive condition, she was perceived as more indifferent and insensitive when in the unattractive condition. From the results of this study, it -was concluded that people do not necessarily alter their persuasive technique according to the attractiveness of the target person. Possible explanations for these findings are discussed, and suggestions for further research are given.

title: Magazine Training Trials and Context Effects on Autoshaping
Creators: name: Oberdieck, Fernando G.
Publisher: name: Utah State University

description: In the autoshaping preparation subjects are exposed to magazine training (US-only trials) prior to the conditioning phase in which a stimulus (conditioned stimulus, CS) predicts the delivery of a response independent reinforcer (unconditioned stimulus, US). Two experiments examined the hypothesis that irrespective of the number of US-only trials administered the magazine training and autoshaping contexts interact to determine conditioning, as measured by contact responses to the CS. The contexts employed were houselight on (light, L) and houselight off (dark, D).
In Experiment I pigeons were exposed to 1, 20, 100, or 900 US-only trials in a D, or L, context prior to autoshaping in the D, or L. The results indicated that first, autoshaping in the L was superior to autoshaping in the D. Second, irrespective of the autoshaping context performance was better following magazine training in the different context. Third, the function relating performance to the number of US-only trials was an inverted U if magazine training occurred in the D and biphasic if it occurred in the L, irrespective of the autoshaping context.
In Experiment II pigeons were exposed to 900 US-only trials in a D, or L, context. Prior to autoshaping in the D, or L, they were exposed to either the magazine training, or a novel, context; this constituted extinction of the US-only context. The results demonstrated that when magazine training and autoshaping occur in the D extinction in the magazine training context results in superior performance relative to extinction in a novel context. However, extinction in a novel context results in better performance, relative to extinction of the magazine training context, if magazine training and autoshaping proceed in the L.
In summary, conditioning in the autoshaping paradigm is determined by the magazine training and autoshaping contexts and their interaction. The development of conditioning is therefore dependent on both the associative value of the CS and the background stimuli.

description: Motivated by recent results of $N$th order muffin-tin orbital (NMTO) implementation of the density functional theory (DFT), we re-examine low-temperature ground-state properties of the anti-ferromagnetic insulating phase of vanadium sesquioxide V$_2$O$_3$. The hopping matrix elements obtained by the NMTO-downfolding procedure differ significantly from those previously obtained in electronic structure calculations and imply that the in-plane hopping integrals are as important as the out-of-plane ones. We use the NMTO hopping matrix elements as input and perform a variational study of the ground state. We show that the formation of stable molecules throughout the crystal is not favorable in this case and that the experimentally observed magnetic structure can still be obtained in the atomic variational regime. However the resulting ground state (two $t_{2g}$ electrons occupying the degenerate $e_g$ doublet) is in contrast with many well established experimental observations. We discuss the implications of this finding in the light of the non-local electronic correlations certainly present in this compound.

title: The California Psychological Inventory and Intrinsic-Extrinsic Religious Motivation
Creators: name: Small, Ken
Publisher: name: Utah State University
Year: 1982

description: The focus of the study was to investigate the nature of the apparent inconsistency reported in the literature on the relationship between personality variables and indices of religiosity. The literature indicates that indices of religiosity have been associated with labels both of "desirable" and "undesirable" personality traits to varying degrees, and no definitive conclusions have been thus far reached. The study suggested that the inconsistent evidence has been a result of a narrow definition of personality functioning and a broad definition of religiosity that has not allowed an adequate test of the relationship between personality and religiosity. The study developed the notion that a multidimensional personality measure (California Psychological Inventory -- CPI) paired with (1) a theoretically precise and psychometrically researched index of religiosity (i.e., Intrinsic Religious Motivation Scale -- IRMS) and (2) a traditional index of religiosity (i.e., denominational membership) might provide new information relative to the relationship between religiosity and personality.
The CPI and the IRMS were administered to 108 male and female Baptist, Church of Jesus Christ of Latter Day-Saints (LOS) and Presbyterian denominational members. CPI subscale scores and IRMS scores were analyzed by a Pearson product-moment correlational analysis, a univariate analysis of variance, and a step-wise multiple discriminate analysis. Significant correlations between IRMS scores and CPI subscale scores were found; however the variance explained was not sufficient to be of theoretical use. There were statistically significant mean differences among denominations (Baptists, LOS, Presbyterians) and between types of religious motivation (intrinsics and extrinsics defined by an IRMS score median split) on the CPI subscales. It was noted that all CPI subscale means fell within the normal range and were not clinically significant. Subjects characterized by denominational membership and religious motivation were characterized by normal personality functioning. Discriminant functions were computed which predicted group membership based on the CPI subscales at accuracy level s between 63.7% and 87.5%. It was argued that tests available to researchers do not allow an adequate test of the relationship between personality and religiosity. It was recommended that researchers study the relationship between religiosity and personality by directly examining subjects' behaviors in combination with utilizing test inventories.
Electrical properties and defect structure of cuprous chloride

Year: 2011

description: Measurements of electrical conductivity (σ), thermoelectric power (θ) and transport numbers in the temperature range 24 - 240°C have been made on CuCl in the pure state and after reaction with chlorine to varying extents. Attempts to measure the Hall Effect gave negative results for all samples. Data for pure CuCl confirm earlier reports that conduction is electronic (positive hole) at low temperatures and ionic (cation inter- stitials) at higher temperatures (above 160°C, for our samples). For the low-temperature range, the significance of various reported apparent activation energies of conduction (E[sub σ]) has been clarified in the present work in terms of an acceptor level at E[sub A] = 0.51 eV above the valance band (cation vacancy as trapping site). The purest samples show "compensated" behaviour, E[sub σ] = E[sub A]. Less pure samples show "uncompensated" behaviour, E being close to E[sub A]/2. % ionic conduction has been estimated in three ways: from the conductivity data, from classical gravimetric transport number measurements, and from the θ - T curve (which has not previously been interpreted, although measurements of θ have been reported by other workers). The behaviour of slightly-chlorinated CuCl (which conducts much better than pure CuCl) correlates with current interpretations of the conduction mechanism in NiO. Conduction is electronic (i.e. not ionic) at all temperatures (24 - 240°C). The θ - T curves have a pronounced maximum at about 100°C. They can be explained, and correlated with σ data, only on the basis of two conduction mechanisms in parallel, by holes in the valence band and electrons "hopping" at the acceptor level with an activation energy of migration E[sub µn] = 0.36 eV. At low temperatures, electron conduction predominates and E[sub σ] = E[sub µn]. Above 100 - 110°C, hole conduction predominates and E[sub σ] = E[sub µn] (as for the lower range in pure CuCl). An energy calculated from the rising portion of the θ - T curve correlates well with (E[sub A] - E[sub µn]), as theory predicts it should. CuCl reacted extensively with chlorine (20 - 65% conversion to CUCI₂) shows conduction phenomena believed to be those of the CuCl component of the heterogeneous solid, but with E[sub σ] = 0.88 eV (high T, > 50% conversion) and 0.15 eV (low T, > 20% conversion). Conduction is by holes-(contradicting an earlier suggestion from this laboratory that the higher value was for cation interstitials), and the higher value is assigned as another acceptor level, E[sub A] = 0.88 eV, probably for anion interstitials as hole traps. The lower value has not been fully explained. The origin of the two different trap depths, E[sub A] = 0.51 and 0.88 eV, is briefly considered, and it is suggested that the difference between them, 0.37 eV, may represent approximately the crystal field splitting of Cu 3d t2 orbitals from Cu 3de orbitals in the tetrahedral site symmetry of CuCl.

description: Magnetic properties of polycrystalline samples of RuSr$_2$(Gd$_{1.5}$Ce$_{0.5}$)Cu$_{2}$O$_{10-δ}$, as-prepared (by solid-state reaction) and annealed (12 hours at 845$^{\circ}$C) in pure oxygen at different pressure (30, 62 and 78 atm) are presented. Specific heat and magnetization were investigated in the temperature range 1.8--300 K with a magnetic field up to 8 T. Specific heat, $C(T)$, shows a jump at the superconducting transition (with onset at $T\approx 37.5$ K). Below 20 K, a Schottky-type anomaly becomes apparent in $C(T)$. This low-temperature anomaly can be attributed to splitting of the ground term ${^8}S_{7/2}$ of paramagnetic Gd$^{3+}$ ions by internal and external magnetic fields. It is found that curves $C(T)$ taken for different values of magnetic field have the same crossing point (at $T_{\ast}\approx 2.7$ K) for all samples studied. At the same time, $C(H)$ curves taken for different temperatures have a crossing point at a characteristic field $H_{\ast}\approx 3.7$ T. These effects can be considered as manifestation of the crossing-point phenomenon which is supposed to be inherent for strongly correlated electron systems.

A topological model for a 3-dimensional spatial information system
Creators: name: Pigot, SP
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis proposes the topological theory necessary to extend the conventional topological models used in geographic information systems (GIS), computer-aided design (CAD) and computational geometry, to a 3-dirnensional spatial information system (SIS) which supports query and analysis of spatial relationships. To encompass a wide range of applications and minirniz.e fragmentation, we define a spatial object as a cell complex, where each k-cell is homeomorphic to a Euclidean kmanifold with one or more subdivided (k-1)-manifold boundary cycles. The sirnplicial and regular cell complexes currently used in topology and many spatial information systems, are restricted forms of these generaliz.ed regular cell complexes. Spatial relationships between the cells of the generalized regular cell complex are expressed 4i terms of their boundary and coboundary cells. To support query and traversal of the neighborhood of any cell via orderings of its cobounding cells, we embed the generalized regular k-cell complex in a Euclidean n-manifold which we represent as a 'world' n-cell. Spatial relationships between spatial objects can be expressed in terms of the boundary and co boundary relations between the cells of another complex formed from the union of the generalized regular cell complexes. If this complex is embedded in a Euclidean nmanifold, then co bounding cells may also be ordered. The cells of this complex have 'singular manifold' or 'pseudomanifold' boundary cycles, which we classify into three primitive types using identification spaces. The cell complex is known as the generaliz.ed singular cell complex - generalized regular, regular and simplicial complexes are restricted forms of this complex. To represent these cell complexes, we extend the implicit cell-tuple of Brisson (1990) since it encapsulates the boundary-coboundary relations and the ordering information. Topological operators are defined to construct spatial objects. Since the set of spatial objects has few restrictions, we define topological operators which consistently construct both subdivided manifolds and manifolds with boundary, from the strong deformation retract of a manifold with boundary. The theory underlying these operators is based on combinatorial homotopy. Generic versions of these topological construction operators can then be used to join these subdivided manifolds or manifolds with boundary, to form the generalized regular cell complex.

We present a twist-3 single-spin-dependent cross section formula for the pion production in pp-collision, p^\uparrow p\toπX, relevant to RHIC experiment. In particular, we calculate the soft-fermion-pole (SFP) contribution to the cross section from the quark-gluon correlation functions. We show that its effect can be as large as the soft-gluon-pole (SGP) contribution owing to the large SFP partonic hard cross section, even though the derivative of the SFP function does not participate in the cross section.

description: We have used Spitzer/IRAC to conduct a photometric monitoring program of the IC1396A dark globule in order to study the mid-IR (3.6 - 8 micron) variability of the heavily embedded Young Stellar Objects (YSOs) present in that area. We obtained light curves covering a 14 day timespan with a twice daily cadence for 69 YSOs, and continuous light curves with approximately 12 second cadence over 7 hours for 38 YSOs. Typical accuracies for our relative photometry were 1-2% for the long timespan data and a few mmag, corresponding to less than 0.5%, for the 7 hour continuous "staring-mode" data. More than half of the YSOs showed detectable variability, with amplitudes from ~0.05 mag to ~0.2 mag. About thirty percent of the YSOs showed quasi-sinusoidal light curve shapes with apparent periods from 5-12 days and light curve amplitudes approximately independent of wavelength over the IRAC bandpasses. We have constructed models which simulate the time dependent spectral energy distributions of Class I and I I YSOs in order to attempt to explain these light curves. Based on these models, the apparently periodic light curves are best explained by YSO models where one or two high latitude photospheric spots heat the inner wall of the circumstellar disk, and where we view the disk at fairly large inclination angle. Disk inhomogeneities, such as increasing the height where the accretion funnel flows to the stellar hotspot, enhances the light curve modulations. The other YSOs in our sample show a range of light curve shapes, some of which are probably due to varying accretion rate or disk shadowing events. One star, IC1396A-47, shows a 3.5 hour periodic light curve; this object may be a PMS Delta Scuti star.

description: A thin film Polytetrafluoroethylene (PTFE) coating was applied to as-received (AR), manually polished (MP), and sandblasted (SB) surfaces of 60 mm diameter, 10 mm thick aluminium discs cut from a circular cross section rod to produce samples with different areal surface roughness parameters. This resulted in different water contact angles and different degrees of hydrophobicity. Experiments were performed to determine how the solidification behaviour of two PCMs; erythritol, a polar molecule, and polyethylene glycol 6000 (PEG 6000), a non-polar molecule were influenced by surface characteristics. The coated manually polished sample with measured areal surface roughness parameters, 𝑆𝑎=1.02±1.30μm, 𝑆𝑠k=0.04, and 𝑆𝑘u=2.69 increased the time to phase change onset of a 2 g sample of erythritol (placed on the surface and then melted) by 93% compared to the aluminium surface without a PTFE thin film. The fabricated surfaces which were superhydrophobic had a strong effect on the shape formed by hot erythritol liquid due to the polar characteristics of the erythritol molecule. Using superhydrophobic thin film coatings on heat exchanger surfaces to modify the solidification behaviour of polar molecules like erythritol, can have potential applications in Latent Heat Thermal Energy Storage (LHTES) systems by modifying charge/discharge performance.

description: The cholinergic hypothesis has long been a “polar star” in drug discovery for Alzheimer’s disease (AD), resulting in many small molecules and biological drug candidates. Most of the drugs marketed for AD are cholinergic. Herein, we report our efforts in the discovery of cholinesterases inhibitors (ChEIs) as multi-target-directed ligands. A series of tacrine-ferulic acid hybrids have been designed and synthesised. All these compounds showed potent acetyl-(AChE) and butyryl cholinesterase(BuChE) inhibition. Among them, the optimal compound 10g, was the most potent inhibitor against AChE (electrophorus electricus (eeAChE) half maximal inhibitory concentration (IC50) = 37.02 nM), it was also a strong inhibitor against BuChE (equine serum (eqBuChE) IC50 = 101.40 nM). Besides, it inhibited amyloid β-protein self-aggregation by 65.49% at 25 μM. In subsequent in vivo scopolamine-induced AD models, compound 10g obviously ameliorated the cognition impairment and showed preliminary safety in hepatotoxicity evaluation. These data suggest compound 10g as a promising multifunctional agent in the drug discovery process against AD.
title: The Development of S+ and S- Rules in Matching-To-Sample by Pigeons Through Prior Autoshaping

description: The purpose of this study was to develop behavior by the pigeon illustrative of S+ and S- rules and to examine if behavior consistent with a concept rule interpretation developed. In order to examine this possibility six groups of pigeons (N=31) were provided different histories of autoshaping. Histories involved the identity of the color of the lighted center key and one side key of three horizontally mounted pigeon keys. Center key onset was followed three seconds later by onset of either outer key. Outer key onset was followed six seconds later by food presentation (explicitly paired) or 45 seconds later, during the inter-trial interval (explicitly unpaired). The foregoing reinforcement conditions were factored into two stimulus conditions, one where the center and side keys were lit by the same hue (identity) and one where the center and side key were lit by different hues (nonidentity). Two groups received identity stimulus sequences with explicitly unpaired food presentation. Two groups were exposed to nonidentity stimulus sequences with explicitly unpaired food presentation. One group received sessions combining exposure to both the explicitly paired identity and explicitly unpaired nonidentity trials. One group received no pretraining. Following pretraining, all birds were placed in a simultaneous matching-to-sample task utilizing the same hues used during pretraining. After reaching criterion on matching-to-sample, on a random ratio 3 schedule of reinforcement, birds were exposed to transfer tests, with a novel hue, to assess for S+ rules, S- rules, and a concept rule. The results indicated that there were no significant differences among groups in terms of their acquisition of matching-to-sample or in terms of their performance on transfer tests. All birds' responding during transfer conditions provided evidence of S+ rules, but neither demonstration of S- rules nor concept rule performance was evidenced. During autoshaping, birds in the identity, explicitly paired groups responded primarily to the center key, suggesting that the stimulus on the outer key was not a salient stimulus for the identity discrimination. For birds in the nonidentity, explicitly unpaired groups neither the center nor outer key controlled responding. For the group combining identity, explicitly paired and nonidentity, explicitly unpaired trials, the birds failed to form a discrimination between types of trials.

description: This resource is a single blog post created as part of the Day of Archaeology initiative. 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.

description: We have derived and solved numerically the Boltzmann-Vlasov transport equations that includes both two-body collisions and the chiral phase transition by mean of NJL-field dynamics. The scope is to understand if the field dynamics supply new genuine effects on the build-up of the elliptic flow $v_2$, a measure of the asymmetry in the momentum space, and in particular if it can affect the relation between $v_2$ and the shear viscosity to entropy ratio $η/s$. Solving the transport equation with a constant cross section for the condition of $Au+Au$ collisions at $\sqrt{s_{NN}}=200$ AGeV it is shown a sizable suppression of $v_2$ due to the attractive nature of the field dynamics that generates the constituent mass. However the key result is that if $η/s$ of the system is kept fixed by an appropriate local renormalization of the cross section the $v_2$ does not depend on the details of the collisional and/or field dynamics and in particular it is not affected significantly by the chiral phase transition.
