description: Assessing vulnerability to food insecurity is instrumental to addressing food security challenges in developing countries. Food production rate in Nigeria is not keeping pace with its population growth rate and this is a serious case for concern with respect to food availability to feed the teeming population. Against this backdrop, this study examined the determinants of vulnerability to food insecurity in Ekiti Sate, Nigeria by applying statistical and econometric tools. Three-stage random sampling procedure was used to elicit cross-sectional data from a total of 150 rural households across 5 local government areas (LGAs) of Ekiti State using semi-structured questionnaire. The Coping Strategy Index (CSI) was used to assess vulnerability to food insecurity status of the households and ordered logit regression was used to identify the factors affecting vulnerability. Findings revealed that 35.33% of the households were moderately vulnerable, while 33.33% and 31.33% were mildly and severely vulnerable, respectively in the study area. Borrowing food, eating seed stock, begging for food and reducing meals were the major coping strategies adopted by the households. Regression results show that out of the 10 significant variables, age of household head, number of dependents, non-food expenditure and number of coping strategies positively influenced vulnerability while being married, educational level, farm income and off-farm occupation negatively influenced vulnerability to food insecurity among the households. The study concluded that policies that address capacity building, increased rural income and its source diversification are likely to enhance resilience of rural farming households in the study area.

description: We present a scheme for probabilistic teleportation via a non-maximally entangled GHZ state. Quantum teleportation will succeed with a certain probability if the sender makes a generalized Bell state measurement, the cooperator performs a generalized $X$ basis measurement, and the receiver introduces an auxiliary particle, performs a collective unitary transformation and makes a measurement on the auxiliary particle. The success probability of the teleportation is given. We also obtain the maximum of the success probability of the teleportation.

description: The quantum state of a superconducting qubit nonresonantly coupled to a transmission line resonator can be determined by measuring the quadrature amplitudes of an electromagnetic field transmitted through the resonator. We present experiments in which we analyze in detail the dynamics of the transmitted field as a function of the measurement frequency for both weak continuous and pulsed measurements. We find excellent agreement between our data and calculations based on a set of Bloch-type differential equations for the cavity field derived from the dispersive Jaynes-Cummings Hamiltonian including dissipation. We show that the measured system response can be used to construct a measurement operator from which the qubit population can be inferred accurately. Such a measurement operator can be used in tomographic methods to reconstruct single and multiqubit states in ensemble-averaged measurements.

Subjects: subject: Computation and Language (cs.CL)

description: Proofs, in Ludics, have an interpretation provided by their counter-proofs, that is the objects they interact with. We follow the same idea by proposing that sentence meanings are given by the counter-meanings they are opposed to in a dialectical interaction. The conception is at the intersection of a proof-theoretic and a game-theoretic accounts of semantics, but it enlarges them by allowing to deal with possibly infinite processes.
A study of Part 3 Local Government (Building & Miscellaneous Provisions) Act 1993 (TAS) : is it effective regulation for subdivision in Tasmania?
Creators: name: Hamilton, AMH
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis studies Part 3 of the Local Government (Building & Miscellaneous Provisions) Act 1993 (Tas), which is the prevailing legislation for subdivision in Tasmania. As such, Part 3 plays an important role in Tasmania's planning regulatory system. That system is currently the subject of significant reform. The reform program does not, however, include a review of Part 3. The study undertaken by this thesis conducts a limited review of Part 3 and that study and review is informed by theory as to the effectiveness of regulation. Regulatory theorists identify review of regulation as an important means of ensuring it is effective. Such review serves to identify issues that detract from the effectiveness of regulation and is a means by which regulation may be refined and remain relevant and efficient. This study notes issues that reduce the effectiveness of Part 3 as regulation of subdivision in Tasmania. Those issues include out-dated, unclear language, provisions that reflect now redundant policy, and cumbersome procedures. This study also raises other broader and more far-reaching issues. The lack of integration of Part 3 into the planning system established under the Land Use Planning and Approvals Act 1993 (Tas) has implications for the ability of Tasmania's planning system to operate as a cohesive and integrated whole. This examination also highlights the uneasy interaction between subdivision regulation as part of a planning system founded in public policy and the Torrens land registration system that is focused on the registration of paramount interests in land. This study of Part 3 Local Government (Building & Miscellaneous Provisions) Act 1993 (Tas) calls attention to the complexities that arise from that interaction and points to some of the implications of failing to adequately address them.

description: We revisit the issue of the recent dynamical evolution of clusters of galaxies using a sample of ACO clusters with z<0.14, which has been selected such that it does not contain clusters with multiple velocity components nor strongly merging or interacting clusters, as revealed in X-rays. We use as proxies of the cluster dynamical state the projected cluster ellipticity, velocity dispersion and X-ray luminosity. We find indications for a recent dynamical evolution of this cluster population, which however strongly depends on the cluster richness. Poor clusters appear to be undergoing their primary phase of virialization, with their ellipticity increasing with redshift with a rate de/dz ~ 2.5, while the richest clusters show an ellipticity evolution in the opposite direction (with de/dz ~ -1.2), which could be due to secondary infall. When taking into account sampling effects due to the magnitude-limited nature of the ACO cluster catalogue we find no significant evolution of the cluster X-ray luminosity, while the velocity dispersion increases with decreasing redshift, independent of the cluster richness, at a rate dsigma/dz ~ -1700 km/sec.

Matrix isolation - I.R. studies: oxygen-fluorine discharges and the photolysis of cis-thionylimide
Creators: name: Tchir, Peter Oryst
Publisher: name: University of British Columbia
Year: 2011

description: Oxygen-fluorides: Attempts have been made at identifying O₃F₂ in the condensate of oxygen fluorine discharges using i.r. spectroscopy. O₂F₂, (O₂F)₂ , OF₂ , OF and O₃ have been observed and numerous overtones and combinations have been measured and assigned for the first time. No evidence could be found for the presence of an species suggesting that “O₃F₂” is actually a mixture of O₂F₂ and (O₂F)₂. The confirmation of the previously reported spectrum of solid O₂F₂ has been made and a careful analysis of the normal coordinate calculations has resulted in a preference for a force field for O₂F₂ with f [sub ∞]= 7.14 aJ/Å² in contrast to the previously reported calculations which found f [sub ∞]= 10.25 aJ/Å². cis-HNSO: The spectra of cis-HNSO and its isotopic homologs containing ¹⁵N, D and ³⁴S have been obtained in Ar and N₂ matrices. A force field with 11 parameters (containing 3 interaction constants) has been calculated from the 29 observed frequencies. The u.v. and vacuum u.v. photolysis of cis-HNSO has been carried out in Ar matrices with the identification of 6 new species from their i.r. spectra. Complete spectra have been observed for cis-HOSN and trans-HSNO, four modes for trans-HNSO, two modes for SNO and one mode for cis-HSNO and NSO. Using isotopic substitution, assignments have been made in all cases and approximate force fieldshave been obtained for cis-HOSN, trans-HSNO and trans-HNSO using guessed structures. The following reaction scheme has been determined from kinetic studies.[See Thesis for Equations]
Charged perfect fluid disks as sources of Taub-NUT-type spacetimes

description: The interpretation of a family of electrovacuum stationary Taub-NUT-type fields in terms of finite charged perfect fluid disks is presented. The interpretation is mades by means of an "inverse problem" approach used to obtain disk sources of known solutions of the Einstein or Einstein-Maxwell equations. The diagonalization of the energy-momentum tensor of the disks is facilitated in this case by the fact that it can be written as an upper right triangular matrix. We find that the inclusion of electromagnetic fields changes significatively the different material properties of the disks and so we can obtain, for some values of the parameters, finite charged perfect fluid disks that are in agreement with all the energy conditions.

The role of satire in the media : Stephen Colbert and John Oliver in the 2016 US election
Creators: name: Evans, LJ
Publisher: name: University Of Tasmania
Year: 2023

description: Satirical programmes such as The Late Show and Last Week Tonight have become valuable commodities in the political media landscape as they have become a trustworthy source for the politically engaged consumer. The continued saturation of news borne through the 24-hour news cycle and the presence of the internet has made the consumer's imperative for honesty and perspective even more valuable. These ideals have paradoxically become connected with satire. Such programs aim to shine a light on the folly and deceit of institutional power while building their own masses of active and engaged audiences. This thesis will investigate the role of satire in political media, with a focus on the work of Stephen Colbert and John Oliver during the 2016 United States election, from the initial campaign process in 2015 through to the two hosts' reflections on the eventual result in 2017. Consideration will be given to satire's value as distraction media‚ÄövÑvp as well as a narrative analysis of the brand of the two hosts before, during and after the 2016 US election. It will also contemplate the growing nexus between news satire and conventional reporting and how this affects traditional journalism and more broadly, democracy through consideration of semiotics and theories of how media circulates via social media

description: Die deutschen Hochschulen stehen heute vor grossen und vielfältigen Herausforderungen, um den aktuellen und zu-künftigen Erwartungen der Gesellschaft gerecht zu werden (Barlett & Chase, 2013). Studierende sollten einerseits die Anforderungen der aktuellen Arbeitsmärkte erfüllen, andererseits sollte die Universität selbst als Bildungseinrichtung und Unternehmen eine Vorbildfunktion einnehmen. Das Konzept der „Nachhaltigen Entwicklung“ und der Bildung für nachhaltige Entwicklung ist derzeit ein Ansatz, den Hochschulen weltweit und insbesondere in Deutschland zunehmend aufgreifen. In Deutschland haben einige Hochschulen bereits Fortschritte bei der Umsetzung des gesamtinstitutionellen Ansatzes erreicht und können als Modell für andere Hochschulen auf dem Weg zu mehr Nachhaltigkeit dienen. Ziel dieses Artikels ist es, die Katholische Universität Eichstätt-Ingolstadt (KU) als positives Beispiel für eine deutsche Universität vorzustellen, die sich seit zwölf Jahren auf dem Weg zu einer nachhaltigeren Universität befindet und damit nach Filho (2009) zur Gruppe der Universitäten gehört, die sich langfristig der Nachhaltigkeit verpflichtet haben (Hemmer & Lindau, 2021). Es ist hervorzuheben, dass neben Forschung und Lehre vier weitere Handlungsfelder (Governance, Studentische Initiativen und Engagement, Campusmanagement und -betrieb sowie Transfer) im Zusammenhang mit Nachhaltigkeit zur Umsetzung eines gesamtinstitutionellen Ansatzes wesentliche Aspekte darstellen. Dieser stringente und systemische Ansatz ist in Deutschland noch zu selten in diesem Umfang und dieser Komplexität zu beobachten (HRK, 2017). Mit diesen Ausführungen kann anderen Hochschulen einerseits eine Vorstellung von einer nachhaltigen Hochschule vermittelt und anderseits ermutigt werden, mit der Umsetzung von Bildung für nachhaltige Entwicklung (BNE) zu beginnen, ihre Bemühungen fortzusetzen und die gesamte Universität nachhaltiger zu gestalten. Die Ausführungen beziehen sich zum grossen Teil auf die Dokumentation der jährlich veröffentlichten Nachhaltigkeitsberichte der KU (https://www.ku.de/unileben/nachhaltige-ku/nachhaltigkeitsbericht).

description: We explore the abundance of light clusters in asymmetric nuclear matter at subsaturation density. With increasing density, binding energies and wave functions are modified due to medium effects. The method of Albergo, Costa, Costanzo and Rubbino (ACCR) for determining the temperature and free nucleon density of a disassembling hot nuclear source from fragment yields is modified to include, in addition to Coulomb effects and flow, also effects of medium modifications of cluster properties, which become of importance when the nuclear matter density is above 10$^{-3}$ fm$^{-3}$. We show how the analysis of cluster yields, to infer temperature and nucleon densities, is modified if the shifts in binding energies of in medium clusters are included. While, at low densities, the temperature calculated from given yields changes only modestly if medium effects are taken into account, larger discrepancies are observed when the nucleon densities are determined from measured yields.

description: We report on the first investigation of the quasiparticle local density of states and superconducting gap in the iron chalcogenide superconductor Fe$_{1+δ}$Se$_{1-x}$Te$_{x}$ ($T_{\mathrm{c}} \sim 14$ K). The surface of a cleaved crystal revealed an atomic square lattice, superimposed on the inhomogeneous background, with a lattice constant of $\sim 3.8$ Åwithout any reconstruction. Tunneling spectra measured at 4.2 K exhibit the superconducting gap, which completely disappears at 18 K, with a magnitude of $\sim 2.3$ meV, corresponding to $2Δ/ k_{\mathrm{B}}T_{\mathrm{c}}=3.8$.In stark contrast to the cuprate superconductors, the value of the observed superconducting gap is relatively homogeneous, following a sharp distribution with a small standard deviation of 0.23 meV. Conversely, the normal-state local density of states observed above $T_{\mathrm{c}}$ shows spatial variation over a wide energy range of more than 1 eV, probably due to the excess iron present in the crystal.

description: The scope of this study was to examine profitability and determine the factors influencing diversification strategies among rice farmers that participated in Kogi Accelerated Rice Production Programme (KARPP). Primary data were obtained through multistage sampling procedure from 216 participating farmers. Descriptive statistics, gross margin, Gini coefficient, Lorenz curve and Tobit models were employed for data analysis. The results showed that the average total cost (TC) incurred by the farmers was ₦127,981.00/ha, with a gross margin of ₦182,092.20/ha and net farm income of ₦159,592.00. The return on investment (ROI) was 1.25 implying that for every one naira invested in rice production, a profit of ₦1.25 was recorded. This indicates that rice production is profitable in the study area. The study also revealed that 52.3% of the farmers had an income greater than ₦90,000. The Gini Coefficient recorded was 0.729 which implied a greater degree of income inequality among the participant. The findings revealed that variables such as sex (p<0.01), age (p<0.01), marital status (p<0.01), household size (p<0.1), farming experience (p<0.01) and extension contact (p<0.01) were the main determinants of diversification strategies. It is recommended that extension service delivery to rice farmers should be strengthened by government and non-governmental organisation through increased funding of extension agencies. Finally, it is suggested that any policy aimed at improving the livelihood strategies of the rice farmers should at least for now target both primary and secondary occupations. There is also the need for Kogi government state to scale up the programme to other non-beneficiary communities.
Exploring the basis of confidence in recognition : psychophysical approach vs. an inferential approach to ecphoric confidence ratings
Creators: name: Kohl, AT
Publisher: name: University Of Tasmania
Year: 2023

description: We investigated whether ecphoric confidence ratings were best accounted for by psychophysical or inferential models of metacognition. 60 participants (43 female; aged 16 to 75 years), undertook a facial recognition task. Participants saw a mix of full and partial faces at both test and study (partial faces displayed the top half of the face), and provided ecphoric confidence ratings (indexing recognition without a yes/no decision) for each face at test on a coarse-grained verbal or fine-grained probabilistic scale. Inferential models of metacognition propose that additional information at test, regardless of its diagnosticity, increases confidence. Therefore, we would expect confidence to be higher in trials where participants viewed a partial face at study (TS) followed by the corresponding full face at test (FT), than when they viewed a partial face followed by the corresponding partial face (TT). Psychophysical models, in contrast, propose that confidence indexes stimulus discriminability, and should be unaffected by additional non-diagnostic information, TS/FT = TS/TT. The doubt-scaling model argues that non-diagnostic information should decrease confidence, and therefore TS/TT > TT/FT. Linear mixed effects models supported the doubt-scaling account. However, these results must be interpreted with caution given potential limitations. Scale type did not affect results

description: The absence of vacuum Cherenkov radiation for 104.5 GeV electrons and positrons at LEP combined with the observed stability of 300 GeV photons at the Tevatron constrains deviations of the speed of light relative to the maximal attainable speed of electrons. Within the Standard-Model Extension (SME), the limit $-5.8\times10^{-12} \leq \tildeκ_{\rm tr}-{4/3}c_e^{00} \leq 1.2\times10^{-11}$ is extracted, which sharpens previous bounds by more than 3 orders of magnitude. The potential for further refinements of this limit with terrestrial experiments and astrophysical observations is discussed.

Microwave spectroscopic studies of chloryl fluoride and acetaldehyde-D1
Creators: name: Parent, Charles Robert
Publisher: name: University of British Columbia
Year: 2011

description: The microwave spectra of three isotopic species of chloryl fluoride, ³⁵Cl¹⁶O₂F, ³⁷Cl¹⁶O₂F, and ³⁵Cl¹⁶O¹⁸OF, have been measured and the transitions fit to Watson's nonrigid rotor reduced Hamiltonian. The resulting rotational constants have allowed the calculation of a molecular structure that features an anomalously long Cl-F bond and unusually short Cl-O bonds. The nuclear quadrupole coupling constants and electric dipole moment have also been determined and both suggest the withdrawal of considerable electron density from the CIO₂ moiety along the Cl-F bond. The molecular structure and ionic character of the Cl-F bond are consistent with a modification of the multicentered molecular orbital bonding theory proposed by Lipscomb and expanded by Spratley and Pimentel. Chloryl fluoride may profitably be viewed as a molecule created by the formation of a bond between a fluorine atom and a stable paramagnetic chlorine dioxide molecule. Qualitatively the anomalously long Cl-F bond results from overlap of a fluorine 2p atomic orbital with a lobe of the highest singly occupied antibonding molecular orbital of CIO₂. The significant contraction of the CI-O bond in CIO₂F, compared to the bond in CIO₂, suggests that there is considerable electron withdrawal from this CIO₂ antibonding orbital. Similar bonding pictures are used to correlate the anomalous structures of NO₂F, NOF, NSF, O₂F₂, and S₂F₂. The rotational constants and barrier to internal rotation of the CH₃CDO isotopic species of acetaldehyde have been determined. The barrier is in good agreement with barrier heights of other isotopic species previously measured, and the rotational constants are consistent with the recent zero-point average structure reported by Iijima and Tsuchiya.

description: We calculate the new contribution to the direct CP-violation parameter $ε'$ in $K\to ππ$ decay in the minimal left-right symmetric model with the recently-obtained right-handed quark Cabibbo-Kobayashi-Maskawa mixing. We pay particular attention to the uncertainty in the hadronic matrix element of a leading four-quark operator $O^{LR}_-$. We find that it can be related to the standard model electromagnetic penguin operator $O_8$ through $SU(3)_L \times SU(3)_R$ chiral symmetry. Using the lattice and large $N_c$ calculations, we obtain a robust constraint on the minimal left-right symmetric scale $M_{W_R}>5$ TeV from the experimental data on $ε'$.

Effect of mindfulness versus self-talk on dart throwing
Creators: name: Franja, S
Publisher: name: University Of Tasmania
Year: 2023

description: Understanding how athletes can achieve ideal performance states is a growing facet of sports psychology. However, most research in this area has predominantly focused on control-based strategies such as self-talk (ST) while acceptance based strategies such as mindfulness meditation (MM) are less well explored. Based on this empirical gap in the research, the aim of the present study was to investigate, and compare the effects of these two opposing strategies on dart throwing performance. Specifically, it investigated how a 10-day ST intervention versus a 10-day MM intervention affected dart throwing performance across both cognitive and non-cognitive loaded environments. Fifty-two participants (30 female; aged 18-63 years, M = 31.28, SD = 10.96) engaged in cognitive training (mindfulness, self-talk, Lumosity[control]) for ten consecutive days prior to the testing session. During the testing session, participants were given a practice round opportunity (cognitive load absent), before engaging in the competition round (cognitive load present). The present study identified two key findings: (1) MM intervention appeared to be most beneficial in the early stages of skill acquisition; and (2). Controlling one's mental state may be unnecessary and unrelated to enhanced athletic performance, regardless of cognitive load.
The effects of feedback on item-by-item and global judgments of learning

description: This study examined the effect of accurate feedback and biased feedback (inflated and deflated), in the form of marks, on the accuracy of item-by-item and global judgments of learning (JOL). 80 participants (49 females, M\\(_{age}\\) = 29.61, SD = 12.76) were randomly allocated into one of four conditions: no feedback, accurate feedback, inflated feedback and deflated feedback. Using a computer program, participants studied 50 Swahili-English word-pairs, and judged the likelihood of remembering each item (item-by-item JOL) and the overall percentage of likely remembered word-pairs after each learning session (global JOL). Immediately after each learning session, a testing session was held. The accurate feedback group received accurate marks after the first and second testing session. The inflated feedback group received marks increased by 32 percent; the deflated feedback group ‚Äö- marks decreased by 32 percent. There were three study-test phases. Feedback did not affect item-by-item JOL accuracy. Deflated feedback significantly reduced global JOL accuracy with a large effect size (d = 1.16), suggesting that participants are sensitive to deflated feedback, which can potentially affect their theory-based cues about their ability to learn

description: During the past years the understanding of the multi-scale interaction problems have increased significantly. However, at present there exists a range of different analytical models for investigating multi-scale interactions and hardly any specific comparisons have been performed among these models. In this work, two different models for the generation of zonal flows from ion-temperature-gradient (ITG) background turbulence are discussed and compared. The methods used is the coherent mode coupling model and the wave kinetic equation model (WKE). It is shown that the two models give qualitatively the same results even though the assumption on the spectral difference is used in the (WKE) approach.

Dicke model: entanglement as a finite size effect

description: We analyze Dicke model at zero temperature by matrix diagonalization to determine the entanglement in the ground state. In the infinite system limit the mean field approximation predicts a quantum phase transition from a non-interacting state to a Bose-Einstein condensate at a threshold coupling. We show that in a finite system the spin part of the ground state is a bipartite entangled state, which can be tested by probing two parts of the spin system separately, but only in a narrow regime around the threshold coupling. Around the resonance, the size of this regime is inversely proportional to the number of spins and shrinks down to zero for infinite systems. This spin entanglement is a non-perturbative effect and is also missed by the mean-field approximation.

description: We report the results of our intensive intranight optical monitoring of 8 `radio-intermediate quasars' (RIQs) having flat or inverted radio spectra. The monitoring was carried out in {\it R-} band on 25 nights during 2005-09. An intranight optical variability (INOV) detection threshold of $\sim$ 1--2% was achieved for the densely sampled differential light curves (DLCs). These observations amount to a large increase over those reported hitherto for this rare and sparsely studied class of quasars which can, however, play an important role in understanding the link between the dominant varieties of powerful AGN, namely the radio-quiet quasars (RQQs), radio-loud quasars (RLQs) and blazars. Despite the probable presence of relativistically boosted nuclear jets, clear evidence for INOV in our extensive observations was detected only on one night. These results demonstrate that as a class, RIQs are much less extreme in nuclear activity compared to blazars. The availability in the literature of INOV data for another 2 RIQs conforming to our selection criteria allowed us to enlarge the sample to 10 RIQs (monitored on a total of 42 nights for a minimum duration of $\sim 4$ hours per night). The absence of large amplitude INOV $(ψ> 3%)$ persists in this enlarged sample. This extensive database has enabled us to arrive at the first estimate for the INOV Duty Cycle (DC) of RIQs. The DC is found to be small ($\sim$ 9%). The corresponding value is known to be $\sim 60%$ for BL Lacs and $\approx 15%$ for RLQs and RQQs. On longer-term, the RIQs are found to be fairly variable with typical amplitudes of $\approx$ 0.1-mag. The light curves of these RIQs are briefly discussed in the context of a theoretical framework proposed earlier for linking this rare kind of quasars to the much better studied dominant classes of quasars.

Parental alienation workshop : a pilot program for targeted parents
Creators: name: Ferber, MS
Publisher: name: University Of Tasmania
Year: 2023

description: The aim of the current study was to evaluate a pilot program that was designed specifically to support targeted parents. Emerging research on the experience of targeted parents suggests their mental health is impacted by parental alienation and they report dissatisfaction with ill-informed systems of intervention and support. Some authors offer guidelines on how to support targeted parents and propose Cognitive Behavioural Therapy (CBT) as a suitable therapy, however there are no known programs in the literature dedicated to supporting the targeted parent. Single subject analysis of participants (N = 5) indicated that following attending a one-day psychoeducation and CBT-based workshop, some participants reported improvement in their psychological wellbeing. On average participants found the program very helpful and were very satisfied with the experience. Qualitative data illuminated the importance of validating the experiences of targeted parents when supporting them and the role of shame in the experience of targeted parents as an area for future research

description: Categorical universal algebra can be developed either using Lawvere theories (single-sorted finite product theories) or using monads, and the category of Lawvere theories is equivalent to the category of finitary monads on Set. We show how this equivalence, and the basic results of universal algebra, can be generalized in three ways: replacing Set by another category, working in an enriched setting, and by working with another class of limits than finite products. An important special case involves working with sifted-colimit-preserving monads rather than filtered-colimit-preserving ones.

description: The environmental impact of metal complexes such as organotin(IV) compounds is of increasing concern. Genotoxic effects of organotin(IV) compounds (0.01 microg/ml, 0.1 microg/ml or 1.0 microg/ml) were measured using the alkaline single-cell gel electrophoresis (comet) assay to measure DNA single-strand breaks (SSBs) and the cytokinesis-block micronucleus (CBMN) assay to determine micronucleus formation. Biochemical-cell signatures were also ascertained using attenuated total reflection Fourier-transform infrared (ATR-FTIR) spectroscopy. In the comet assay, organotin(IV) carboxylates induced significantly-elevated levels of DNA SSBs. Elevated micronucleus-forming activities were also observed. Following interrogation using ATR-FTIR spectroscopy, infrared spectra in the biomolecular range (900 cm-1 - 1800 cm-1) derived from orga...

description: We report on the results of a six-month photometric study of the main-belt binary C-type asteroid 121 Hermione, performed during its 2007 opposition. We took advantage of the rare observational opportunity afforded by one of the annual equinoxes of Hermione occurring close to its opposition in June 2007. The equinox provides an edge-on aspect for an Earth-based observer, which is well suited to a thorough study of Hermione's physical characteristics. The catalog of observations carried out with small telescopes is presented in this work, together with new adaptive optics (AO) imaging obtained between 2005 and 2008 with the Yepun 8-m VLT telescope and the 10-m Keck telescope. The most striking result is confirmation that Hermione is a bifurcated and elongated body, as suggested by Marchis et al., (2005). A new effective diameter of 187 +/- 6 km was calculated from the combination of AO, photometric and thermal observations. The new diameter is some 10% smaller than the hitherto accepted radiometric diameter based on IRAS data. The reason for the discrepancy is that IRAS viewed the system almost pole-on. New thermal observations with the Spitzer Space Telescope agree with the diameter derived from AO and lightcurve observations. On the basis of the new AO astrometric observations of the small 32-km diameter satellite we have refined the orbit solution and derived a new value of the bulk density of Hermione of 1.4 +0.5/-0.2 g cm-3. We infer a macroscopic porosity of ~33 +5/-20%.

description: Numerical estimates for pair production from vacuum in the presence of strong electromagnetic fields are derived, for two experimental schemes : the First concerns a laser based X-FEL and the other imitates the E144 experiment. The approximation adopted in this work is that of two level multiphoton on resonance. Utilizing achievable values of laser beam parameters, an enhancedproduction efficiency of up to 10^11 and 10^15 pairs can be obtained, for the two schemes respectively.

Local well-posedness for membranes in the light cone gauge

description: In this paper we consider the classical initial value problem for the bosonic membrane in light cone gauge. A Hamiltonian reduction gives a system with one constraint, the area preserving constraint. The Hamiltonian evolution equations corresponding to this system, however, fail to be hyperbolic. Making use of the area preserving constraint, an equivalent system of evolution equations is found, which is hyperbolic and has a well-posed initial value problem. We are thus able to solve the initial value problem for the Hamiltonian evolution equations by means of this equivalent system. We furthermore obtain a blowup criterion for the membrane evolution equations, and show, making use of the constraint, that one may achieve improved regularity estimates.

description: EDELWEISS is a direct dark matter search experiment situated in the low radioactivity environment of the Modane Underground Laboratory. The experiment uses Ge detectors at very low temperature in order to identify eventual rare nuclear recoils induced by elastic scattering of WIMPs from our Galactic halo. We present results of the commissioning of the second phase of the experiment, involving more than 7 kg of Ge, that has been completed in 2007. We describe two new types of detectors with active rejection of events due to surface contamination. This active rejection is required in order to achieve the physics goals of 10-8 pb cross-section measurement for the current phase.

description: Photoproduction of $Λ$(1520) with liquid hydrogen and deuterium targets was examined at photon energies below 2.4 GeV in the SPring-8 LEPS experiment. For the first time, the differential cross sections were measured at low energies and with a deuterium target. A large asymmetry of the production cross sections from protons and neutrons was observed at backward K$^{+/0}$ angles. This suggests the importance of the contact term, which coexists with t-channel K exchange under gauge invariance. This interpretation was compatible with the differential cross sections, decay asymmetry, and photon beam asymmetry measured in the production from protons at forward K$^+$ angles.

Uncertainty in medical decision making : the impact of icon arrays and graph literacy
Creators: name: Stanton, EJ
Publisher: name: University Of Tasmania
Year: 2023

description: We investigated whether icon arrays help to make deficits in participants' comprehension of health risk information salient, especially for participants with low graph literacy (ability to read and use information depicted in graphs). 240 participants (126 female; average age: 27 years) were recruited through Prolific Academic. We presented treatment risk scenarios with either numbers only or numbers with icon arrays, and participants chose between two treatments or an explicit I don't know‚ÄövÑvp option. We included letter strings as a cognitive load manipulation, and measures of graph literacy and numeracy. Contrary to hypotheses, only numeracy affected participants' comprehension, ˜ìv°\\(^2\\) = 16.85, \\(p\\) <.001, \\(f\\) = 0.10, and calibration, ˜ìv°\\(^2\\) = 20.06, \\(p\\) <.001, \\(f\\) = 0.11, with no significant interaction between graph condition (icon vs numbers) and graph literacy. Our findings call into question the ways in which icon arrays are beneficial for presenting risk information. Future research should further investigate how appropriate icon arrays are for presenting risk information, and explore the utility of an I don't know‚ÄövÑvp option in these scenarios.
