description: We report a systematic measurement of the space charge effect observed in the few-ps laser pulse regime in laser-based solid-state photoemission spectroscopy experiments. The broadening and the shift of a gold Fermi edge as a function of spot size, laser power, and emission angle are characterized for pulse lengths of 6 ps and 6 eV photon energy. The results are used as a benchmark for an $N$-body numerical simulation and are compared to different regimes used in photoemission spectroscopy. These results provide an important reference for the design of time- and angle-resolved photoemission spectroscopy setups and next-generation light sources.

End-to-End Target Detection Enhanced by Hierarchical Convolution Modulation and Sparse Attention Transmission
Creators: name: Guangzhuang, Yao
Publisher: name: Zenodo
Year: 2024

description: This study proposes an end-to-end target detection model that significantly improves accuracy, particularly for both large and small targets. The key innovations lie in the hierarchical convolution modulation of deformable attention and a sparse feature transmission strategy. By modulating deformable attention with convolution, our approach enables effective extraction of both global and local features. Additionally, a deep-shallow layered convolutional module is employed to enhance coarse- and fine-grained feature extraction. The sparse transmission strategy ensures optimal feature output from the encoder layers. Experimental results on the MS-COCO dataset demonstrate the effectiveness of our approach, achieving state-of-the-art performance with notable gains in detection accuracy for both small and large targets.

description: Accretion disks with masses ~0.001-0.1 Msun form during the merger of neutron star (NS)-NS and black hole-NS binaries. Initially, such hyper-accreting disks cool efficiently by neutrino emission and their composition is driven neutron-rich by pair captures under degenerate conditions. However, as the disk viscously spreads and its temperature drops, cooling becomes inefficient and the disk becomes advective. Analytic arguments and numerical simulations suggest that once this occurs, powerful winds likely drive away most of the disk's remaining mass. We calculate the thermal evolution and nuclear composition of viscously spreading accretion disks formed from compact object mergers using one-dimensional height-integrated simulations. We show that freeze-out from weak equilibrium necessarily accompanies the disk's late-time transition to an advective state. As a result, hyper-accreting disks generically freeze out neutron-rich (with electron fraction Ye ~ 0.2-0.4), and their late-time outflows robustly synthesize rare neutron-rich isotopes. Using the measured abundances of these isotopes in our solar system, we constrain the compact object merger rate in the Milky Way to be < 1e-5 (M_d,0/0.1 Msun)^(-1) per year, where M_d,0 is the average initial mass of the accretion disk. Thus, either the NS-NS merger rate is at the low end of current estimates or the average disk mass produced during a typical merger is << 0.1 Msun. We also show that if most short duration gamma-ray bursts (GRBs) are produced by compact object mergers, their beaming fraction must exceed f_b ~ 0.13(M_d,0/0.1 Msun), corresponding to a jet half-opening angle > 30(M_d,0/0.1 Msun)^(1/2) degrees. This is consistent with other evidence that short duration GRB outflows are less collimated than those produced in long duration GRBs.

The push towards compliance : domestic culture, legitimacy, and compliance with the European Court of Human Rights
Creators: name: Jay, ZC
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis seeks to explain why states comply with the European Court of Human Rights (ECtHR) by developing a constructivist account of how state actors use domestic ideas about rights and law to assess the legitimacy of international law. Building on the constructivist assumption that actors feel a 'pull towards compliance' when they believe the law is legitimate, this thesis seeks to understand where such beliefs come from, and how they translate into compliance. The thesis therefore endeavours to address three questions: First, what makes states perceive international law as legitimate? Second, how do such perceptions of legitimacy translate into decisions to comply with particular ECtHR judgments? Third, which types of ECtHR cases are states likely to comply with or resist? The thesis advances the concept of domestic rights cultures, arguing that states' unique historical experiences, constitutional traditions, and interactions with European and international institutions create specific understandings and expectations about what law and human rights are, and what they should be. Rights cultures thus serve as a filter through which international laws are interpreted, and as a standard against which they must be assessed, in order for state actors to determine whether particular international laws should be considered legitimate, and particular ECtHR judgments complied with. In developing this concept, the thesis addresses two interrelated lacunae in existing theoretical explanations of compliance, where scholars of International Relations and International Law have failed both to provide a convincing account of where the legitimacy that ostensibly pulls states towards compliance comes from, and to fully appreciate domestic cultural and historical understandings of rights and law as a potential source of that legitimacy. It thus contributes a richer theoretical and empirical account of the domestic cultural and historical forces that underpin state actors' conceptualisations of legitimacy, and motivate their decisions to comply with ECtHR judgments. Through interpretive analysis and comparison of three case studies ‚Äö- the United Kingdom, Germany, and Croatia ‚Äö- the thesis examines the core ideas and experiences that constitute states' rights cultures, and their effect on states' relationships with the ECtHR and approaches to compliance with its judgments. It finds that states draw on their unique domestic understandings of rights and law not only to evaluate the legitimacy of ECtHR judgments, but ‚Äö- in some cases ‚Äö- actively rely on domestic understandings to cajole themselves towards compliance. In this way, the thesis reveals that the relationship between domestic culture, legitimacy, and international law does not necessarily generate a 'pull' towards compliance from the international system or the law itself, but a 'push', that stems from states' domestically constructed perceptions of the legitimacy of international law.
Testing a model to predict depression, anxiety and stress in parents of children with attention-deficit/hyperactivity disorder
Creators: name: Scott, SL
Publisher: name: University Of Tasmania
Year: 2023

description: Parents of children with ADHD experience levels of distress that negatively impact child, parent, and family functioning. However, current treatment approaches for ADHD focus on child interventions and disregard the effect of parental distress. Falk et al. (2014) developed Model A, further validated by Bones (2017), to demonstrate that the relationship between parental distress and child-centric variables (child social/interpersonal deficits and externalising behaviour) is mediated by parent-centric variables (socio-economic support and maladaptive parental cognitions) in ASD populations. The current study aimed to validate Model A in an ADHD population. This study recruited 142 parents of children aged 4 to 17 years old, with and without ADHD. Participants completed an online survey including measures of socio-economic support, maladaptive parental cognitions, child social/interpersonal deficits, and child externalising behaviour. Hierarchical regression was conducted and results indicated that parents of children with ADHD had significantly higher levels of distress compared to parents of typically developing children and that the variables in Model A were significant predictors of parental distress. Results suggest that parent-centric factors, particularly maladaptive parental cognitions, are important predictors of distress in ADHD parents. This study illustrates a need to focus on interventions that target parental distress when treating children with ADHD.

A Cyclic electrodialysis process : investigation of closed systems
Creators: name: Bass, Dieter
Publisher: name: University of British Columbia
Year: 2011

description: The cyclic electrodialysis process combines two concepts. The idea of flow reversal from parametric pumping is applied to an electrically driven absorption-desorption process operating with a stack of three-layer, ion-selective membranes. The cyclic process was investigated for the demineraliza-tion of aqueous NaCl solutions in a closed system. The standard parametric pumping operation was found to be generally very inefficient because of the finite rates of mass transfer. Flow pauses after each polarity reversal substantially improved both the rate and the limit of separation. Two designs of the electrodialysis cell were studied. Ten system parameters were analysed on a simple bench scale cell. Final separations were limited by large axial dispersion and ranged between 1 and 40. A second electrodialysis cell consisted of up to eight single stages (15 [cm] channel length) which were usually operated in series hydraulically and in parallel electrically. Final separation factors ranged between 2 and ~6000. Large separation factors were achieved for long channels, long pause times, and high applied potentials. The initial rate of separation appeared to be a maximum for a channel length of approximately one meter and pause times of about ten seconds. During the first few cycles the separation factor could be approximated by an exponential function of time. The potential of the process for continuous separation in open systems was demonstrated. Models of the closed systems are presented and are used to discuss the experimental results.

description: In three previous discussions, we investigated the travels of Marco Polo, with the help of Google Earth and Wikimapia. We reconstructed Polo’s travels from Beijing to Xanadu, from Sheberghan to Kashgar, and from Kashgar to Xanadu. Here we propose Polo's travel in Persia. The place of a Mulehet Castle, close to Ferdows in the Tunocain county, is also evidenced. It is possible that Marco Polo was referring to this castle, the Ghal'eh Kuh of Ferdows, when he was reporting about the Old Man of the Mountain, and not to the Alamut Castle in the South Caspian province of Qazvin.
The effect of Modafinil on behavioural and ERP measures of attention and associated sex differences
Creators: name: Shaw, HM
Publisher: name: University Of Tasmania
Year: 2023

description: Modafinil is a wakefulness-promoting drug that is becoming more commonly used for off-label for attentional enhancement in healthy individuals despite conflicting evidence to support this. The aim of the current study was to investigate the effects of modafinil on behavioural (reaction time & accuracy) and ERP (N1 amplitude) measures of the attentional alerting and orienting networks and also investigate any sex differences associated with these effects. The final sample consisted of 14 females and 22 males who were all healthy and met the screening criteria. Each participant completed two sessions differing by drug condition (200mg modafinil or placebo). The Attentional Network Task was used to assess the effects on both the alerting and orienting network and this task was completed at baseline and at 2.5 hours post-ingestion. As expected, reaction time decreased and N1 amplitude increased as cues became more informative. There was a small enhancement of the alerting network demonstrated by a significant decrease in reaction time from baseline to post-ingestion for central cues in the modafinil condition but not placebo. There was a small significant decrease in reaction time from baseline to post-ingestion for spatial cues but this is likely due to alerting enhancement rather than orienting as the effects were of similar size. Inconsistent to the hypotheses, males had a faster reaction time to all cue types when compared to females. Males also showed greater N1 amplitude after modafinil ingestion than placebo, indicating some sex differences in the effect of modafinil may be present. These results suggest that modafinil may have an enhancing effect on the alerting network but not the orienting network. The effects of modafinil on the orienting network has not been well studied so future research is required to confirm this finding. There also appears to be differential effects of modafinil on males and females, which also requires future investigation as this is the first study to look at these effects.

description: Mountains on rapidly rotating neutron stars efficiently radiate gravitational waves. The maximum possible size of these mountains depends on the breaking strain of neutron star crust. With multi-million ion molecular dynamics simulations of Coulomb solids representing the crust, we show that the breaking strain of pure single crystals is very large and that impurities, defects, and grain boundaries only modestly reduce the breaking strain to around 0.1. Due to the collective behavior of the ions during failure found in our simulations, the neutron star crust is likely very strong and can support mountains large enough so that their gravitational wave radiation could limit the spin periods of some stars and might be detectable in large scale interferometers. Furthermore, our microscopic modeling of neutron star crust material can help analyze mechanisms relevant in magnetar giant and micro flares.

description: We consider the efficiency of chemical energy extraction from the environment by the growth of a copolymer made of two constituent units in the entropy-driven regime. We show that the thermodynamic nonlinearity associated with the information processing aspect is responsible for a branching of the system properties such as power, speed of growth, entropy production, and efficiency, with varying affinity. The standard linear thermodynamics argument which predicts an efficiency of 1/2 at maximum power is inappropriate because the regime of maximum power is located either outside of the linear regime or on a separate bifurcated branch, and because the usual thermodynamic force is not the natural variable for this optimization.

description: The effects of spin and charge fluctuations and electron-phonon couplings on charge ordering in α-(BEDT-TTF)_2I_3 (BEDT-TTF=bis(ethylenedithio)-tetrathiafulvalence) are investigated theoretically for an anisotropic triangular lattice at 3/4 filling. By the exact-diagonalization method, we have calculated the hole density distributions and the modulations of transfer integrals from high-temperature values as a function of electron-phonon coupling strength. The results clearly show that the lattice effect on α-(BEDT-TTF)_2I_3 is weak compared with that on θ-(BEDT-TTF)_2RbZn(SCN)_4, as previously found by experiments. This finding, which is also consistent with recent mean-field results, is systematically explained by strong-coupling perturbation theory; the effects of spin fluctuations are partially canceled by charge fluctuations in α-(BEDT-TTF)_2I_3.

description: We offer a piece of evidence that the problems of finding the number of mutually unbiased bases (MUB) and mutually orthogonal Latin squares (MOLS) might not be equivalent. We study a particular procedure which has been shown to relate the two problems and generates complete sets of MUBs in power-of-prime dimensions and three MUBs in dimension six. For these cases, every square from an augmented set of MOLS has a corresponding MUB. We show that this no longer holds for certain composite dimensions.

N2pc modulation as an electrophysiological marker of output-based inhibitory cueing effects
Creators: name: Skerratt, SS
Publisher: name: University Of Tasmania
Year: 2023

description: An inhibitory cueing effect (ICE) is a phenomenon whereby behavioural responses (such as a manual keypress or saccade) to stimuli appearing at recently attended locations are slowed, provided that time elapsed is sufficient for the extinction of early facilitation effects. This phenomenon, often referred to as inhibition of return (IOR), is thought to be a functional component of visual search which facilitates novelty seeking. Research has demonstrated two dissociable mechanisms underlying ICEs ‚Äö- input-based and output-based. The present study used a modified spatial cueing task with both active and suppressed oculomotor-states, combined with electroencephalography (EEG) measurement, to investigate whether the deployment of covert visual attention (measured as the amplitude of N2pc) is modulated differentially by input and output-based ICEs. Additionally, the present study sought to examine the effect of attentional deficits on both behavioural inhibition (manual response times) and the modulation of deployed attention. Behavioural results showed that ICEs were elicited, however the observed inhibition was identical across oculomotor-state. The effect of group was marginally significant, with post-hoc analyses revealing a significant difference between uncued and cued targets in the control group (slower to cued), but only marginal significance for the deficit group. No significant results were found for N2pc analyses, however a polarity inverse to that expected was observed. Results, interpretations, and recommendations for future research are discussed.
Manufacture of sodium dithiouite from sodium-mercury amalgam and aqueous solution of sulfur dioxide
Creators: name: Nayar, Raman
Publisher: name: University of British Columbia
Year: 2011

description: A relatively dilute (approximately 1 to 2%) water solution of sodium dithionite was produced from sodium-mercury amalgam and aqueous solution of sulfur dioxide in a simple "once through" reactor [proposed process]. The reactor could be run in conjunction with the Castner-Kellner type cell. The manufactured solution could then be used directly for the brightening of groundwood pulp. The bench scale experiments were carried out in a continuous-flow-stirred-tank reactor where the aqueous and amalgam phases formed an interface. The effects of important process variables on the steady-state concentration of sodium dithionite in the reactor and yields of sodium dithionite on sulfur dioxide in the aqueous feed and on sodium consumed in a single pass were determined. The above-mentioned yields are important in assessing the economic feasibility of the proposed process. The steady-state yield of sodium dithionite on sodium in the amalgam entering the reactor and conversion of sodium to different products in the reactor were also determined. The present investigation showed that the process variables can be controlled to give approximately 2.3% sodium dithionite solution with steady-state Na₂S₂O₄ yields of about 21% on sulfur dioxide in the aqueous feed and about 67% on sodium consumed. The yields obtained depend on the levels of process variables such as: 1. the concentration of sodium in the amalgam entering the reactor, 2. the concentration of total sulfur dioxide in the aqueous feed solution, 3. the agitation in the aqueous phase, 4. the agitation in the amalgam phase, 5. the residence time in the aqueous phase, 6. the residence time in the amalgam phase, 7. the interfacial-area/aqueous-volume ratio, 8. the temperature of the aqueous phase, and 9. the pH of the aqueous phase. This experimental study indicates that it may be economically feasible for a pulp mill to change .from zinc dithionite produced in situ to sodium dithionite produced in situ by the proposed; process. Further, the proposed process compared to the manufacture of zinc dithionite in situ avoids the discharge of zinc ions which act as biocidal agents when discharged into the effluent receiving waters. The models suggested by Ketelaar (44) and Gerritsen (30) were found inadequate to explain the processes occurring in the reacting system sodium-mercury amalgam and aqueous sulfur dioxide. A qualitative model has been suggested on the basis of the experimental work and the information available in the literature. This work also sheds some light on the type of reactor which would be suitable for the proposed process.

description: Quantum key distribution (QKD) promises unconditionally secure key generation between two distant parties by wisely exploiting properties of quantum mechanics. In QKD, experimental measurements on quantum states are transformed to a secret key and this has to be done in accordance with a security proof. Unfortunately, many theoretical proofs are not readily implementable in experiments and do not consider all practical issues. Therefore, in order to bridge this "practical gap", we integrate a few existing theoretical results together with new developments, in effect producing a simple and complete recipe for classical post-processing that one can follow to derive a secret key from the measurement outcomes in an actual QKD experiment. This integration is non-trivial and our consideration is both practical and comprehensive in the sense that we take into account the finiteness of the key length and consider the effects on security of several essential primitives (including authentication, error handling, and privacy amplification). Furthermore, we quantify the security of the final secret key that is universally composable. We show that the finite-size effect mainly comes from phase error estimation. Our result is applicable to the BB84 protocol with a single or entangled photon source.

description: The process of determining the contribution of an almost forgotten couturier, Jo Mattli, to the British fashion and textile industry, has resulted in a deep study of the under-researched London couture scene of the mid-twentieth century. This thesis is distinctive in providing object-based evidence of Mattli’s response to the social and financial changes experienced in Britain post World War II, and unusual for using primary documentary evidence to trace the business history of a London couture house. Based on Prown’s model of object-based material culture research, supported by the inter-disciplinary methodologies of socio-cultural, socio-economic, structuralist and oral history, this thesis makes a unique contribution to the body of knowledge of dress history.
Using primary evidence to explore the production and consumption of Mattli couture, ready-to-wear, boutique and wholesale clothing, tests and challenges the theoretical perspectives critically analysed in the thesis. A case study using primary Mattli artefacts tests Prown’s methodology. Simmel, Lipovetsky and Bourdieu’s differing theories of the fashion system, taste, and luxury, are analysed, tested and challenged. Barthes’ semiotic theory is tested against image and text, and Lacan’s psychoanalytical theory challenged for its relevance to the consumption of Mattli designs. The changing cultural status of the surviving Mattli garments is illuminated by employing Thompson’s theory of rubbish and Kopytoff’s biography of the object technique. Evidence from primary sources is supported by contemporaneous literature and oral history. The latter is used cautiously but effectively to support the primary evidence, and absence of evidence, in turn upholding and challenging traditional theoretical models. Scientific identification of a small sample of fibres from surviving Mattli garments challenges the assumed perception of luxury as applied to couture fabrics mid-twentieth century.
The resulting study contributes to a greater understanding of the design, production and consumption of London couture, identifies both Mattli’s position within London couture and the reasons for him being forgotten. This thesis argues for the rehabilitation of Mattli in dress history and, as the objects provided the most significant evidence, for the importance of object-based research as a primary component of the methodology used in the discipline.

description: Over the years, data mining has attracted most of the attention from the research community. The researchers attempt to develop faster, more scalable algorithms to navigate over the ever increasing volumes of spatial gene expression data in search of meaningful patterns. Association rules are a data mining technique that tries to identify intrinsic patterns in spatial gene expression data. It has been widely used in different applications, a lot of algorithms introduced to discover these rules. However Priori like algorithms has been used to find positive association rules. In contrast to positive rules, negative rules encapsulate relationship between the occurrences of one set of items with absence of the other set of items. In this paper, an algorithm for mining negative association rules from spatial gene expression data is introduced. The algorithm intends to discover the negative association rules which are complementary to the association rules often generated by Priori like algorithm. Our study shows that negative association rules can be discovered efficiently from spatial gene expression data.

description: Within the context of upcoming full-sky lensing surveys, the edge-preserving non- linear algorithm Aski is presented. Using the framework of Maximum A Posteriori inversion, it aims at recovering the full-sky convergence map from surveys with masks. It proceeds in two steps: CCD images of crowded galactic fields are deblurred using automated edge-preserving deconvolution; once the reduced shear is estimated, the convergence map is also inverted via an edge- preserving method. For the deblurring, it is found that when the observed field is crowded, this gain can be quite significant for realistic ground-based surveys when both positivity and edge-preserving penalties are imposed during the iterative deconvolution. For the convergence inversion, the quality of the reconstruction is investigated on noisy maps derived from the horizon N-body simulation, with and without Galactic cuts, and quantified using one-point statistics, power spectra, cluster counts, peak patches and the skeleton. It is found that the reconstruction is able to interpolate and extrapolate within the Galactic cuts/non-uniform noise; its sharpness-preserving penalization avoids strong biasing near the clusters of the map; it reconstructs well the shape of the PDF as traced by its skewness and kurtosis; the geometry and topology of the reconstructed map is close to the initial map as traced by the peak patch distribution and the skeleton's differential length; the two-points statistics of the recovered map is consistent with the corresponding smoothed version of the initial map; the distribution of point sources is also consistent with the corresponding smoothing, with a significant improvement when edge preserving prior is applied. The contamination of B-modes when realistic Galactic cuts are present is also investigated. Leakage mainly occurs on large scales.

Effect of salt concentration and cation valence on maximum yield of a bentonite claypaste
Creators: name: Hu, Chien-Sheng
Publisher: name: University of British Columbia
Year: 2011

description: A review is given on the factors important to the build-up of a gel structure in clay suspensions. The effect of salt is especially stressed. The maximum yield stress of a 19.06 weight per cent washed Bentonite clay paste was measured with a Rotovisco viscometer as a function of the concentration of five salts which were added individually to the paste. The salt concentration was varied from .002 molality up to the coagulation concentration. Two groups of salts were studied; those which had cations in common with the caly: NaCl and CaCl₂, and those found only in trace amounts in clay: CuCl, MnCl₂ and CeCl₃. The behavior of the two groups of salt was quite different. The latter group produced a maximum developable yield value in the clay which was inversely proportional to the valence of the cation. Sodium Chloride produced the largest maximum yield value at a high salt concentration while no yield value could be found for clay with concentrations of CaCl₂ above 0.002M.

description: Galaxies are believed to be in one-to-one correspondence with simulated dark matter subhalos. We use high-resolution N-body simulations of cosmological volumes to calculate the statistical properties of subhalo (galaxy) major mergers at high redshift (z=0.6-5). We measure the evolution of the galaxy merger rate, finding that it is much shallower than the merger rate of dark matter host halos at z>2.5, but roughly parallels that of halos at z<1.6. We also track the detailed merger histories of individual galaxies and measure the likelihood of multiple mergers per halo or subhalo. We examine satellite merger statistics in detail: 15%-35% of all recently merged galaxies are satellites and satellites are twice as likely as centrals to have had a recent major merger. Finally, we show how the differing evolution of the merger rates of halos and galaxies leads to the evolution of the average satellite occupation per halo, noting that for a fixed halo mass, the satellite halo occupation peaks at z~2.5.

description: The Rayleigh-Taylor instability at the interface in an immiscible two-component Bose-Einstein condensate is investigated using the mean-field and Bogoliubov theories. Rayleigh-Taylor fingers are found to grow from the interface and mushroom patterns are formed. Quantized vortex rings and vortex lines are then generated around the mushrooms. The Rayleigh-Taylor instability and mushroom-pattern formation can be observed in a trapped system.

description: We present two sets of grid-based hydrodynamical simulations of high-velocity clouds (HVCs) traveling through the diffuse, hot Galactic halo. These HI clouds have been suggested to provide fuel for ongoing star formation in the Galactic disk. The first set of models is best described as a wind-tunnel experiment in which the HVC is exposed to a wind of constant density and velocity. In the second set of models we follow the trajectory of the HVC on its way through an isothermal hydrostatic halo towards the disk. Thus, we cover the two extremes of possible HVC trajectories. The resulting cloud morphologies exhibit a pronounced head-tail structure, with a leading dense cold core and a warm diffuse tail. Morphologies and velocity differences between head and tail are consistent with observations. For typical cloud velocities and halo densities, clouds with H{\small{I}} masses $< 10^{4.5}$ M$_\odot$ will lose their H{\small{I}} content within 10 kpc or less. Their remnants may contribute to a population of warm ionized gas clouds in the hot coronal gas, and they may eventually be integrated in the warm ionized Galactic disk. Some of the (still over-dense, but now slow) material might recool, forming intermediate or low velocity clouds close to the Galactic disk. Given our simulation parameters and the limitation set by numerical resolution, we argue that the derived disruption distances are strong upper limits.

description: The Networks Mobility (NEMO) Protocol is a way of managing the mobility of an entire network, and mobile internet protocol is the basic solution for Networks Mobility. A hierarchical route optimization system for mobile network is proposed to solve management of hierarchical route optimization problems. In present paper, we study Hierarchical Route Optimization Scheme using Tree Information Option (HROSTIO). The concept of optimization finding the extreme of a function that maps candidate solution to scalar values of quality, is an extremely general and useful idea. For solving this problem, we use a few salient adaptations and we also extend HROSTIO perform routing between the mobile networks.

description: Understanding the charging of exceptionally narrow levels in quantum dots in the presence of interactions remains a challenge within mesoscopic physics. We address this fundamental question in the generic model of a narrow level capacitively coupled to a broad one. Using bosonization we show that for arbitrary capacitive coupling charging can be described by an analogy to the magnetization in the anisotropic Kondo model, featuring a low-energy crossover scale that depends in a power-law fashion on the tunneling amplitude to the level. Explicit analytical expressions for the exponent are derived and confirmed by detailed numerical and functional renormalization-group calculations.

The effects of mindfulness meditation on spectral measures of EEG activity
Creators: name: Bosworth, AM
Publisher: name: University Of Tasmania

description: Mindfulness meditation is associated with improvements in emotional regulation and attention, however the neural mechanisms underlying these relationships are not well understood. Meta-analyses of electrophysiological changes during meditation, indicate that meditative states are most consistently associated with increased alpha and theta power, and preliminary evidence suggests that mindfulness meditation practice may reduce frontal theta/beta ratio, a potential electrophysiological marker of attentional control. However, studies in this area are limited by methodological issues, such as the use of cross-sectional designs and lack of active control groups. This study aimed to address limitations of previous research by conducting a randomised control trial which examines whether electrophysiological changes occur after one week of mindfulness meditation training with neurofeedback. Participants with low meditation experience (N=33) were randomised into a one-week intervention (at least 20 minutes for seven days) of either mindfulness meditation training with neurofeedback or relaxation training with biofeedback. Measures of mindfulness, mood, and emotional regulation were taken at pre training and post training sessions. Results indicated that there was no change in theta power, alpha power or theta/beta ratio, from pre training to post training in the focused breathing condition for both groups, and measures of mindfulness, suggesting that the dose of meditation the experimental group received was not sufficient to lead to changes in electrophysiological measures. Future research could extend the duration of the mindfulness meditation intervention to address this possibility.

description: We present a comparative study of ultrafast photo-conversion dynamics in tetracene (Tc) and pentacene (Pc) single crystals and Pc films using optical pump-probe spectroscopy. Photo-induced absorption in Tc and Pc crystals is activated and temperature-independent respectively, demonstrating dominant singlet-triplet exciton fission. In Pc films (as well as C$_{60}$-doped films) this decay channel is suppressed by electron trapping. These results demonstrate the central role of crystallinity and purity in photogeneration processes and will constrain the design of future photovoltaic devices.

description: A modified f(R) gravity model has been recently proposed in Phys. Rev. Lett. 102, 221101 (2009) [arXiv:0905.1941] whose cosmological behaviour is clearly distinguishable from LCDM. Contrary to previous opinions which consider that self-consistent f(R) gravity models distinct from LCDM are almost ruled out, the authors claim that the proposed model is cosmologically viable. Here we show that although the model satisfies some consistency conditions, precisely because of its departure from LCDM behaviour, it does not satisfy local gravity constraints and, in addition, the predicted matter power spectrum conflicts with SDSS data.
