description: The experimental critical temperatures and gap values of the superconducting pnictides of both the 1111 and 122 families can be simultaneously reproduced within the Eliashberg theory by using a three-band model where the dominant role is played by interband interactions and the order parameter undergoes a sigh reversal between hole and electron bands (s+- wave symmetry). High values of the electron-boson coupling constants and small typical boson energies (in agreement with experiments) are necessary to obtain the values of all the gaps and to correctly reproduce their temperature dependence.

Autonomic mechanisms in spider phobia reactions
Creators: name: Archer, Leanne M
Publisher: name: University Of Tasmania
Year: 2023

description: A strong fear of spiders is classified as a Specific Phobia, Animal Type (American Psychiatric Association, 1994). A number of theories have been suggested as to how this fear develops and how it is expressed in the physiological realm. This review addresses these issues. Systematic desensitisation has been the treatment of choice for phobias for some time. Issues concerning group administration of this procedure are discussed, as are a number of studies into physiological reflections of treatment success. Respiratory sinus arrhythmia (RSA) has been widely accepted as a measure of vagal tone in psychophysiological studies. This review outlines a current theory that explores the physiology of RSA and why it does not always respond in concert with heart rate. The potential implications of the RSA measure for psychophysiology and psychology as a whole are also discussed, as are a number of different variables which can affect the quantification of the RSA measure. The review concludes with an investigation into the possibility of using the RSA measure to specify the nature of the physiological mechanisms of specific phobia, both in terms of the strength of phobic response and also in terms of modifications due to a treatment program.
The effects of alcohol and temazepam upon mismatch negativity
Creators: name: Brumby, Roseanne H
Publisher: name: University Of Tasmania
Year: 2023

description: Mismatch negativity is a component of the auditory event-related potential which is elicited by stimulus change following a series of homogenous stimuli. Mismatch negativity is the subject of some debate regarding whether physical stimulus features are processed and mismatch detection conducted equally well, whether in the presence or absence of attention. Alcohol and temazepam are both drugs which have been found to attenuate other attention dependent components of the ERP. This attenuation is attributed to a reduction of attentional resources. Thus by measuring the effect of attention upon mismatch negativity under the influence of alcohol and temazepam singly, this dilemma may be resolved. If temazepam and alcohol only affect attentional components of the ERP then attenuation would only be expected in ERPs taken in conditions of attention. Furthermore if MMN is attention dependent it would be expected that these drugs administered together may produce an interactive effect upon the amplitude of mismatch negativity.
Maurice Barres "Le cult du moi" : etude du vocaulaire, des themes et images et de la structure
Creators: name: Roland, Michel Albert
Publisher: name: University of British Columbia
Year: 2011

description: La présente étude consacrée au "Culte du Moi" de Barrès n'est ni un essai d'histoire littéraire, ni une étude des sources ¹, ni une thèse à proprement parler. Elle se limite à l'examen le plus scrupuleux possible du texte et ne fait appel à aucun élément d'explication extérieur à lui. Afin de respecter la chronologie essentielle à tout roman d'éducation ou de formation tel que celui-ci, l'auteur a choisi d'analyser les trois livres successivement. C'est l'analyse du vocabulaire qui s'imposait d'abord. A la manière d'un poète, Barrès invente en effet son propre langage et c'est d'abord à ce niveau qu'il se voit "differént" des autres, de ceux qu'il appelle les "barbares". Chacun des termes rencontrés: frisson, ardeur, sécheresse, désolation etc… ont été recensés selon leur fréquence et l'importance qui leur est accordée est relative à la place que chacun d'eux occupe dans "l'ideologie barrésienne". Ils expriment presque toujours des notions antithétiques ou compléntentaires et s'expliquent les uns par les autrese. Il arrive souvent aussi qu'un même mot-clé soit affacté de valeurs divergentes, voire opposes, d'un paragraphe a l'autre, sans que cela fasse contradiction. Ainsi le mot "solitude" a tantôt la valeur négative d 'isolement et d'agonie du Moi, tantôt au contraire la valeur positive d'exaltation et de surhumanité, ou même les deux à la fois. Le sens des mots est si peu figé que leur étude permet de suivre de façon sûre l'éducation du Moi par luimême dans ses rapports avec le monde de la vie active. Le vocabulaire joue un rôle si essentiel dans la conception génerale de l'oeuvre que les deux autres parties de cette étude analytique ne sont que le prolongement et l'élargissement de la première. Chaque notion importante est en effet au centre d'un thème dont on peut suivre les variations du début à la fin de la trilogie à travers les très nombreuses images qui l'expriment concurremment avec les "dialogues idéologiques". Quant à la structure de l'oeuvre, elle n'est pas une non plus et il a fallu en étudier les modalités livre par livre. Dans"Sous l'oeil des barbares", elle reflète le caractère dramatique du conflit et le désarroi du Moi qui ne voit d'autre issue que dans le repli sur soi. Elle se fait plus harmonieuse dans les deux autres volumes, au fur et à mesure oû le Moi se maîtrise et parvient à imposer un équilibre à ses deux parties, dont il ne veut justement sacrifier aucune.

Dietary protein requirement and protein-nitrogen flux in the greenback flounder, Rhombosolea tapirina Gunther 1862
Creators: name: Bharadwaj, AS
Publisher: name: University Of Tasmania
Year: 2023

description: The overall objectives of this study were to estimate protein requirement of and to study nitrogen flux in juvenile greenback flounder, Rhombosolea tapirina Gunther 1862. Six isoenergetic diets (- 17.5MJ Kg\\(^{-1}\\)) containing graded levels of protein ranging from 30-55% (19.24 - 34.70 gDP MJ\\(^{-1}\\) DE) were fed to juvenile (0.45 g) greenback flounder with the aim of estimating its dietary protein requirement. Food consumption decreased with increasing levels of protein in the diet while protein intake increased. Fish feeding on the 45% and 50% protein diets had the highest percent increases in body weight (%BWI), specific growth rates (SGR), productive protein values(PPV) and protein retention efficiencies (PRE). A second degree polynomial (quadratic) model of the form y = a + bx + cx\\(^2\\) was fitted to dose - response data (SGR, % BWI, PPV and PRE). The dietary protein concentration required for optimal growth ranged between 44-48% and the optimal digestible protein to digestible energy ratio was estimated to be 28.14-30.41 g DP MJ\\(^{-1}\\) DE. The daily protein requirement at the maximum specific growth rate of 2.01 % day' was calculated to be 5.84 g kg\\(^{-1}\\) day\\(^{-1}\\). Endogenous and exogenous nitrogen excretion rates of juvenile( 12g) greenback flounder were estimated at 16¬¨‚àûC and nitrogen budgets constructed. Fish were fasted for 48 hours to determine endogenous rates and fish were fed (on a diet containing approx. 46% protein) 1% body weight once a day (Treatment A), 0.5% body weight once a day (Treatment B) and 0.5% body weight twice a day (Treatment C) to determine the effect of ration size and feeding frequency on nitrogen excretion rates. The mean endogenous excretion rate of total nitrogen(TN) was found to be 23.36 mg N kg\\(^{-1}\\) day\\(^{-1}\\) with total ammonia nitrogen (TAN) and urea nitrogen (UN) constituting 82.5 and 10.4% of total nitrogen respectively. The mean exogenous total excretion rates were 402.52 mg N kg\\(^{-1}\\) day\\(^{-1}\\), 236.60 mg N kg\\(^{-1}\\) day\\(^{-1}\\) and 398.34 mg N kg\\(^{-1}\\) day\\(^{-1}\\) for treatments A, B and C respectively. TAN and UN accounted for 83-85% and 8-9% of total nitrogen excreted in all treatments. Fish from treatment B excreted 64.48% and retained 30.52% of nitrogen consumed, while fish from treatments A and C excreted 54% and retained 40% of consumed nitrogen. Excretion rates, retention rates and percentages of consumed nitrogen excreted and retained were significantly (p<0.05) affected by ration size but not by frequency of feeding.

description: We write down exact solutions in the collective field theory of the c=1 matrix model and in dilaton-gravity coupled to a massless scalar. Using the known correspondence between these two theories at the null boundaries of spacetime, we make a connection between scalar fields in these two theories in the bulk of spacetime. In the process, we gain insight into how a theory containing gravity can be equivalent to one without gravity. We analyze a simple time-dependent background as an example.

description: This is a short presentation delivered on 3 February 2022 during the DCU Ethics and Privacy Week as part of the panel entitled "Should social media make us more social?" Drawing inspirations from the philosophy of John Dewey, I look at three issues related to the idea of developing habits of sociability through social media. These include 1) the persistence of online habits in offline contexts, 2) reflectivity and flexibility of these habits versus threats to autonomy, and 3) conflicting interests relating to the definition of sociability and pro-social attitudes.

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: Despite some success in explaining the observed polarisation angle swing of radio pulsars within the geometric rotating vector model, many deviations from the expected S-like swing are observed. In this paper we provide a simple and credible explanation of these variations based on a combination of the rotating vector model, intrinsic orthogonally polarized propagation modes within the pulsar magnetosphere and the effects of interstellar scattering. We use simulations to explore the range of phenomena that may arise from this combination, and briefly discuss the possibilities of determining the parameters of scattering in an effort to understand the intrinsic pulsar polarization.

description: Liquids in contact with solids are submitted to intermolecular forces making liquids heterogeneous and, in a mechanical model, the stress tensor is not any more spherical as in homogeneous bulks. The aim of this article is to show that a square-gradient functional taking into account the volume liquid free energy corrected with two surface liquid density functionals is a mean field approximation allowing to study structures of very thin liquid nanofilms near plane solid walls. The model determines analytically the concept of disjoining pressure for liquid films of thicknesses of a very few number of nanometers and yields a behavior in good agreement with the shapes of experimental curves carried out by Derjaguin and his successors.

description: Modern software systems comprise multiple models. When these models are changed, interdependent models must be evolved accordingly. Manually managing this co-evolution of models is tedious and error-prone. Moreover, other interdependent artefacts, such as persisted states of industrial software applications, must co-evolve accordingly. Automated consistency preservation allows for efficiently managing the co-evolution of models. However, while state-of-the-art approaches operate delta-based, typical software applications persist changes state-based without conforming to explicit metamodels. Additionally, software applications may persist changes infrequently, even though interdependent models might be concurrently modified. As such, current approaches are insufficient for artefacts of industrial tools. To address these issues, we propose an approach for the co-evolution of models and artefacts of industrial tools by treating these artefacts as external views on the models.

description: Conventional local public health planning and monitoring are insufficiently addressing the conjugated impact of urban development change and climate change in the future. The existing checklist and index often ignore the spatial-network interaction determining urban public health services in forward-looking aspects. This study offers and demonstrates a climate-resilient operationalization framework for urban public health services considering the interaction between urban development change and climate change across scales. A combination of collaborative scenario planning and tailor-made composite indicators were applied based on the IPCC Fifth Assessment Report (AR5)’s climate risk concept to adhere to local realities and diverse sets of scenarios. The framework was contested in a medium-sized city with a universal health care coverage setting, Khon Kaen city, Thailand. The results show that the coupling of collaborative scenario planning and composite indicators allows local public health care to operationalize their potential impact and climate-resilient targets in the future(s) in multiple service operation aspects. The scenarios assessment outcomes prove that although public health devotion can be fail-safe, achieving climate-resilient targets requires sectoral integration with urban development and health determining domains. Further exploration and disputation of the framework with a wider scale and diversified settings are recommended to enhance their robustness and universality.

Clustering Properties and Model Wavefunctions for Non-Abelian Fractional Quantum Hall Quasielectrons

description: We present model wavefunctions for quasielectron (as opposed to quasihole) excitations of the unitary $Z_k$ parafermion sequence (Laughlin/Moore-Read/Read-Rezayi) of Fractional Quantum Hall states. We uniquely define these states through two generalized clustering conditions: they vanish when either a cluster of $k+2$ electrons is put together, or when two clusters of $k+1$ electrons are formed at different positions. For Abelian Fractional Quantum Hall states ($k=1$), our construction reproduces the Jain quasielectron wavefunction, and elucidates the difference between the Jain and Laughlin quasielectrons. For two (or more) quasielectrons, our states differ from those constructed using Jain's method. By adding our quasielectrons to the Laughlin state, we obtain a hierarchy scheme which gives rise the non-Abelian non-unitary $ν={2/5}$ FQH Gaffnian state.

description: It is well established now that the solar atmosphere, from photosphere to the corona and the solar wind is a highly structured medium. Satellite observations have confirmed the presence of steady flows. Here, we investigate the parallel propagation of magnetohydrodynamic (MHD) surface waves travelling along an ideal incompressible flowing plasma slab surrounded by flowing plasma environment in the framework of the Hall magnetohydrodynamics. The propagation properties of the waves are studied in a reference frame moving with the mass flow outside the slab. In general, flows change the waves' phase velocities compared to their magnitudes in a static MHD plasma slab and the Hall effect limits the range of waves' propagation. On the other hand, when the relative Alfvenic Mach number is negative, the flow extends the waves propagation range beyond that limit (owing to the Hall effect) and can cause the triggering of the Kelvin--Helmholtz instability whose onset begins at specific critical wave numbers. It turns out that the interval of Alfvenic Mach numbers for which the surface modes are unstable critically depends on the ratio between mass densities outside and inside the flux tube.

Our main result is that any finite word appears on a subsequence discretization with any desired limit frequency.

description: For any thermoelectric effects to be achieved, a thermoelectric material must have hot and cold sides. Typically, the hot side can be easily obtained by excess heat. However, the passive cooling method is often limited to convective heat transfer to the surroundings. Since thermoelectric voltage is proportional to the temperature difference between the hot and cold sides, efficient passive cooling to increase the temperature gradient is of critical importance. Here, we report simultaneous harvesting of radiative cooling at the top and solar heating at the bottom to enhance the temperature gradient for a transverse thermoelectric effect which generates thermoelectric voltage perpendicular to the temperature gradient. We demonstrate this concept by using the spin Seebeck effect and confirm that the spin Seebeck device shows the highest thermoelectric voltage when both radiative cooling and solar heating are utilized. Furthermore, the device generates thermoelectric voltage even at night through radiative cooling which enables continuous energy harvesting throughout a day. Planar geometry and scalable fabrication process are advantageous for energy harvesting applications.

description: The energy bands of a semiconductor are lowered by an external magnetic field. When a field is switched on, the straight-line trajectories near the top of the occupied valence band are curved into Landau orbits and Bremsstrahlung is emitted until the electrons have settled in their final Fermi distribution. We calculate the radiated energy, which should be experimentally detectable, and suggest that a semiconductor can be cooled by an oscillating magnetic field.

description: Many of my photographed situations are temporarily created for the moment of shooting. After being attracted to the original scene, I then proceed in changing the scene with careful and precise placement of props, building materials, pipes, steelwork and so on. Viewed from any angle other than through the camera the scene appears only to be a jumble of shapes. By doing this I am not aiming to document the scene as I found it but to break down the association and functions of real world objects within the scene. Changing the spacial relationships by juxtaposing objects in appropriate places ‚Äöwithin the foreground and background I attempt to challenge the assumptions made by the viewer. Having previously worked with flat, two-dimensional black and white images in a city environment, I found that moving to the country allowed much greater oppurtunity for me to take advantage of its particular quality of light and space. I choose to use colour primarily for it's aesthetic appeal, but also in many photographs as an aid in creating visual ambiguities. I was attracted to work in colour after coming in contact with the work of photographers such as Joel Meyerwitz, John Pfahl, Stephen Shore, William Eggleston and Michael Bishop.
Sequential memory in relation to dyslexic children
Creators: name: Buhr, Joyce Lynn
Publisher: name: University of British Columbia
Year: 2011

description: A group of 48 dyslexic boys was compared with a group of 32 normal boys matched for age and I.Q. Dyslexia was operationally defined as two years reading retardation relative to other abilities in the absence of emotional disturbance, cultural deprivation or obvious physiological damage while maintaining a normal test intelligence. The two groups were compared on a temporally presented sequential memory test in both the visual and auditory modalities and using both pictures and words within the visual mode. The dyslexics performed significantly worse on the sequential memory test and on a recall test with the same stimuli. Moreover, both dyslexics and normals did better auditorally than visually, and pictures were easier than words. The pattern of response was parallel for the two groups with the dyslexic scores just dropped below the normals. A developmental lag theory of causation was strongly indicated by the data.

description: Recent spectro-polarimetric observations have provided detailed measurements of magnetic field, velocity and intensity during events of magnetic field intensification in the solar photosphere. We consider the temporal evolution of the relevant physical quantities for three cases of magnetic field intensification in a numerical simulation. We determine the evolution of the intensity, magnetic flux density and zero-crossing velocity derived from the synthetic Stokes parameters by taking into account the spectral and spatial resolution of the spectropolarimeter (SP) on board Hinode. The three events considered show a similar evolution: advection of magnetic flux to a granular vertex, development of a strong downflow, evacuation of the magnetic feature, increase of the field strength and the appearance of the bright point. We find that synthetic and real observations are qualitatively consistent and, for one of the cases considered, agree very well also quantitatively. The effect of finite resolution (spatial smearing) is most pronounced in the case of small features, for which the synthetic Hinode/SP observations miss the bright point formation and also the high-velocity downflows during the formation of the smaller magnetic features.

description: Advancing the upconversion materials field relies on accurate and contrastable photoluminescence efficiency measurements, which are characterised by the absolute upconversion quantum yield (UCQY). However, the methodology for such measurements cannot be extrapolated directly from traditional photoluminescence quantum yield techniques, primarily due to issues that arise from the non-linear behaviour of the UC process. Subsequently, no UCQY standards exist, and significant variations in their reported magnitude can occur between laboratories. In this work, our aim is to provide a path for determining and reporting the most reliable UCQYs possible, by addressing all the effects and uncertainties that influence its value. Here the UCQY standard, at a given excitation power density, is defined under a range of stated experimental conditions, environmental conditions, material properties, and influential effects that have been estimated or corrected for. A broad range of UCQYs reported for various UC materials are scrutinized and categorized based on our assertion of the provided information associated with each value. This is crucial for improved comparability with other types of photoluminescent materials, and in addition, the next generation of UC materials can be built on top of these reliable standards.

Desiring these solutions as a bridge toward the future for yet more general solutions of the sDiff(2)Toda equation, we generalize the earlier work of Olivier, on the Atiyah-Hitchin metric, and re-formulate work of Babich and Korotkin, and Tod, on the Bianchi IX approach to a metric with an SU(2) of symmetries. We also give careful delineations of the conformal transformations required to ensure that a metric of Bianchi IX type has zero Ricci tensor, so that it is a self-dual, vacuum solution of the complex-valued version of Einstein's equations, as appropriate for the original Plebanski equation.

Year: 2023

description: It is estimated that between 40% and 60% of on-site systems in Australia are not treating domestic wastewater to acceptable levels. This study investigates the viability of constructed wetlands as an alternative form of on-site treatment of domestic greywater in temperate climates. A case study wetland was constructed to treat domestic greywater from a single household, providing an insight into the design, construction, operational performance, hydraulic flow and reed growth of a small-scale wetland operating in Tasmania. A review of current literature provides an insight into constructed wetlands, emphasising their use as a form of on-site wastewater treatment. Interviews with officers from five local government councils indicates that knowledge of constructed wetlands is very limited, but a great deal of interest was shown by the interviewed environmental health officers, who suggested that they may be willing to trial wetlands within their municipalities. All the local governments interviewed were experiencing problems with the current and accepted forms of on-site wastewater treatment. Testing of the case study wetland over a nine-month period showed that pollutant removal processes were occurring across all testing parameters except ammonia and phosphorous. Significant findings from the case study that would improve the quality of the final effluent include the importance of healthy reeds with deep root systems, improving hydraulic flow within the Wetland to prevent short-circuiting, and the necessity of additional pre and post wetland treatment. Greywater alone does not have sufficient nutrients and trace elements to sustain vigorous growth for the common reed, Phragmites australis. A combined flow of black and greywater led to vigorous and healthy reed growth. The wetland produced an effluent with an average of 64 mg/L BOD5 (60% removal), 48.5 mg/L suspended solids (88% removal), 18,427 FCU/100mL faecal coliforms (99.2% removal), 0.008 mg/L nitrite (65% removal), 2.9 mg/L nitrate (6% removal), 2.2 mg/L ammonia, 6.7 mg/L phosphorous, 537 pS/cm conductivity, and a pH of 7.7. It is expected that treatment would improve as the reeds and root systems mature and the design improvements are implemented.

description: In this work the high pressure region of the phase diagram of water has been studied by computer simulation by using the TIP4P/2005 model of water. Free energy calculations were performed for ices VII and VIII and for the fluid phase to determine the melting curve of these ices. In addition molecular dynamics simulations were performed at high temperatures (440K) observing the spontaneous freezing of the liquid into a solid phase at pressures of about 80000 bar. The analysis of the structure obtained lead to the conclusion that a plastic crystal phase was formed. In the plastic crystal phase the oxygen atoms were arranged forming a body center cubic structure, as in ice VII, but the water molecules were able to rotate almost freely. Free energy calculations were performed for this new phase, and it was found that for TIP4P/2005 this plastic crystal phase is thermodynamically stable with respect to ices VII and VIII for temperatures higher than about 400K, although the precise value depends on the pressure. By using Gibbs Duhem simulations, all coexistence lines were determined, and the phase diagram of the TIP4P/2005 model was obtained, including ices VIII and VII and the new plastic crystal phase. The TIP4P/2005 model is able to describe qualitatively the phase diagram of water. It would be of interest to study if such a plastic crystal phase does indeed exist for real water. The nearly spherical shape of water makes possible the formation of a plastic crystal phase at high temperatures. The formation of a plastic crystal phase at high temperatures (with a bcc arrangements of oxygen atoms) is fast from a kinetic point of view occurring in about 2ns. This is in contrast to the nucleation of ice Ih which requires simulations of the order of hundreds of ns.
Explicit gauge covariant Euler-Lagrange equation

description: The application of a gauge covariant derivative to the Euler-Lagrange equation yields a shortcut to the equations of motion for a field subject to an external force. The gauge covariant derivative includes an external force as an intrinsic part of the derivative and hence simplifies Lagrangians containing tensor and gauge covariant fields. The gauge covariant derivative used in the covariant Euler-Lagrange equation is presented as an extension of the coordinate covariant derivative used in tensor analysis. Several examples provide useful demonstrations of the covariant derivative relevant to studies in general relativity and gauge theory.

description: The equation of state of de-confined quark matter within the MIT bag model is calculated. This equation of state is used to compute the structure of a neutron star with quark core. It is found that the limiting mass of the neutron star is affected considerably by this modification of the equation of state. Calculations are carried out for different choices of the bag constant.

description: The growing prevalence of vascular diseases worldwide has emphasized the need for novel tissue-engineered options concerning the development of vascularized 3D constructs. This study reports, for the first time, the use of external magnetic fields to stimulate mesenchymal stromal cells (MSCs) to increase the production of vascular endothelial growth factor-A (VEGF-A). Polyvinylalcohol and gelatin-based scaffolds, containing iron oxide nanoparticles, were designed for optimal cell magnetic stimulation. While the application of static magnetic fields over 24 h did not impact on MSCs proliferation, viability and phenotypic identity, it significantly increased the production of VEGF-A and guided MSCs morphology and alignment. The ability to enhance MSCs angiogenic potential was demonstrated by the increase in the number of new vessels formed in the presence of MSCs conditioned media through in vitro and in vivo models. Ultimately, this study uncovers the potential to manipulate cellular processes through short-term magnetic stimulation.
After the goldrush : the success of ecological restoration following mining in the Box and Ironbark Forests, North Central Victoria

description: The new science of restoration ecology offers those who work towards ecological restoration an evaluative framework for measuring success. This research project considers the restoration work carried out on four mined sites in the Box and Ironbark Forest Ecosystem of North Central Victoria. To measure success, vegetation cover and height, along with thirteen environmental variables and three site characteristics, were recorded in four mine sites and compared to nearby forest controls. It was found that mined sites had fewer native species than the control sites, and soil fertility and litter cover were less. Five floristic communities were described from the mined areas and controls, two of which are restricted to mined areas. Global Non-parametric Multi Dimensional Scaling of the vegetation data and vector fitting of the environmental and site variables also showed that strong floristic differences exist between mined and control areas at most sites. As restoration attempts were similar at each site, ecosystem resilience was considered as the main contributing factor to the different degrees of success. It was found that mined areas with prolonged disturbance regimes shared less in common with their control. Weed cover was not found to be significantly different between the controls and mined areas. This study serves as baseline data for long term research and recommends that clear goals and objectives need to be implemented in determining successful mine site restoration in the Box and Ironbark Ecosystem.

description: Rare-earth-doped nanoparticles (NPs), such as NaGdF4 nanocrystals doped with light-emitting rare earth ions, are promising bimodal probes that allow the integration of over 1000 nm near-infrared (OTN-NIR; NIR-II/III) fluorescence imaging and magnetic resonance imaging (MRI) of live bodies. A precise control of the particle size is the key factor for achieving a high signal-to-noise ratio in both NIR fluorescence and MR images and for regulating their function in the body. In this study, size-controlled NaGdF4:Yb3+, Er3+ NPs prepared by stepwise crystal growth were used for in vivo bimodal imaging. Hexagonal NaGdF4:Yb3+,Er3+ NPs coated with poly(ethylene glycol)-poly(acrylic acid) block copolymer, with hydrodynamic diameters of 15 and 45 nm, were prepared and evaluated as bimodal NPs for OTN-NIR fluorescence imaging and MRI. Their longitudinal (T1) and transverse (T2) relaxation rates at the static magnetic field strength of 1.0 T, as well as their cytotoxicity towards NIH3T3 cell lines, were evaluated and compared to study the effect of size. Using these particles, blood vessel visualization was achieved by MRI, with the highest relaxometric ratio (r1/r2) of 0.79 reported to date for NaGdF4-based nanoprobes (r1 = 19.78 mM−1 s−1), and by OTN-NIR fluorescence imaging. The results clearly demonstrate the potential of the size-controlled PEG-modified NaGdF4:Yb3+,Er3+ NPs as powerful ‘positive’ T1-weight contrast MRI agents and OTN-NIR fluorophores.
An analysis of number conservation ability

description: Seven hypotheses were derived from Piaget's (a) task analysis of the ordinal correspondence and conservation tasks; (b) description of the development from preoperation to concrete operational thinking; and (c) ideas about the necessary and sufficient conditions for this transition. An attempt was also made to solve the methodological problems of (a) how to determine whether a child is a real conserver or a pseudo-conserver; (b) how to determine whether the child understands the terms in a Piagetian task; and (c) variation in performance due to stimulus variables. Twenty-eight four-year-old Ss, 36 kindergarten Ss, and 28 grade one Ss were each given the following seven tests, in addition to a test of counting ability: (1) a test of their ability to match the number of objects in a standard row; (2) a conservation of number test; (3) a test of their ability to anticipate and remember the results of a transformation in a row of objects; (4) a test of the criteria on which they made judgments of quantity; (5) a test of their ability to build two corresponding series of objects; (6) a test of their ability to find ordinal correspondences; and (7) a test of their ability to mentally transform a stimulus. Five of the hypotheses were confirmed and one hypothesis was partially confirmed. The methodological problems were partially solved. A new approach to the development of number conservation ability was suggested by the data.
