Unit propagation with stable watches
Creators: name: Iser, Markus

Publisher: name: Schloss Dagstuhl - Leibniz-Zentrum für Informatik GmbH (LZI)
Year: 2021

description: Unit propagation is the hottest path in CDCL SAT solvers, therefore the related data-structures, algorithms and implementation details are well studied and highly optimized. State-of-the-art implementations are based on reduced occurrence tracking with two watched literals per clause and one blocking literal per watcher in order to further reduce the number of clause accesses. In this paper, we show that using runtime statistics for watched literal selection can improve the performance of state-of-the-art SAT solvers. We present a method for efficiently keeping track of spans during which literals are satisfied and using this statistic to improve watcher selection. An implementation of our method in the SAT solver CaDiCaL can solve more instances of the SAT Competition 2019 and 2020 benchmark sets and is specifically strong on satisfiable cryptographic instances.
The influence of exercise-induced arousal on processes of memory and metamemory
Creators: name: Turner, A
Publisher: name: University Of Tasmania
Year: 2023

description: The benefits of exercise for both physical and psychological wellbeing are well established. The present study aimed to further investigate whether exercise is beneficial for memory and metamemory. Forty-one adults were randomly assigned to either exercise prior to encoding (n = 21) or not exercise (n = 20). Participants studied 100 word pairs and predicted the likelihood of recalling and recognising the target word in a memory test. There were no differences in mean number of words recalled between the exercise and control condition. Exercise had an effect on discrimination and confidence for JOLs, where the exercise condition was worse at discriminating between remembered and forgotten items (p = .003, d = 1.08) and had inflated confidence (p = .019, d = 0.78). There was also an effect of exercise on discrimination for FOKs, where those who exercised were worse at discriminating between items they remembered versus forgot (p = .077, d = 0.69). Although this difference did not reach statistical significance, it was a moderate to large effect. There was no effect of exercise on confidence. The data suggests that exercise prior to studying may be detrimental to both memory performance and the ability to accurately judge one's memory.
Radiative Neutralino Decay in Split Supersymmetry

description: Radiative neutralino decay $χ^0_2 -> χ^0_1γ$ is studied in a Split Supersymmetric scenario, and compared with mSUGRA and MSSM. This 1-loop process has a transition amplitude which is often quite small, but has the advantage of providing a very clear and distinct signature: electromagnetic radiation plus missing energy. In Split Supersymmetry this radiative decay is in direct competition with the tree-level three-body decay $χ^0_2 -> χ^0_1 f\overline f$, and we obtain large values for the branching ratio $B(χ^0_2 -> χ^0_1γ)$ which can be close to unity in the region $M_2 \sim M_1$. Furthermore, the value for the radiative neutralino decay branching ratio has a strong dependence on the split supersymmetric scale $\widetilde{m}$, which is otherwise very difficult to infer from experimental observables.

Topological Entanglement and Clustering of Jain Hierarchy States

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We obtain the clustering properties and part of the structure of zeroes of the Jain states at filling $\frac{k}{2k+1}$: they are a direct product of a Vandermonde determinant (which has to exist for any fermionic state) and a bosonic polynomial at filling $\frac{k}{k+1}$ which vanishes when $k+1$ particles cluster together. We show that all Jain states satisfy a "squeezing rule" (they are "squeezed polynomials") which severely reduces the dimension of the Hilbert space necessary to generate them. The squeezing rule also proves the clustering conditions that these states satisfy. We compute the topological entanglement spectrum of the Jain $ν={2/5}$ state and compare it to both the Coulomb ground-state and the non-unitary Gaffnian state. All three states have very similar "low energy" structure. However, the Jain state entanglement "edge" state counting matches both the Coulomb counting as well as two decoupled U(1) free bosons, whereas the Gaffnian edge counting misses some of the "edge" states of the Coulomb spectrum. The spectral decomposition as well as the edge structure is evidence that the Jain state is universally equivalent to the ground state of the Coulomb Hamiltonian at $ν={2/5}$. The evidence is much stronger than usual overlap studies which cannot meaningfully differentiate between the Jain and Gaffnian states. We compute the entanglement gap and present evidence that it remains constant in the thermodynamic limit. We also analyze the dependence of the entanglement gap and overlap as we drive the composite fermion system through a phase transition.

The effects of alcohol mixed with energy drinks on risk-taking behaviour
Creators: name: Bromfield, HR
Publisher: name: University Of Tasmania
Year: 2023

description: The 'wide-awake drunkenness' hypothesis proposes that consuming alcohol mixed with energy drinks (AmED) masks the sedative effects of alcohol, causing consumers to misperceive their level of intoxication and consequently engage in more risky behaviours (Peacock & Bruno, 2015). Experimental data suggests a trend towards increased risk-taking following AmED consumption driven predominantly by the ED, with small magnitude effects (Lubman, 2013; Peacock, Bruno, Martin, & Carr, 2013). This study examined AmED effects on risk-taking administering standardised ED and alcohol doses, using a naturalistic multi-dose design to mimic how AmEDs are consumed in the 'real-world'. In a placebo-controlled, within-subjects, double-blind study, participants (N=27) consumed alcohol with ED (AmED condition) and soda water (Alcohol-only condition). The Automatic Balloon Analogue Risk Task (A-BART) measured risk-taking propensity, while the Determination Task (DT) was administered to measure frustration tolerance. AmED administration did not significantly increase risk-taking propensity as measured by the A-BART, however Reaction Time (RT) on the DT was improved following AmED ingestion, indicating improved cognitive function relative to alcohol-only, whilst accuracy was not significantly affected. Improved cognitive performance may predict underestimation of intoxication as drinkers gauge their level of impairment based on cognitive cues (Celio et al., 2014). Future research should aim to measure risk-taking behaviour in social drinking environments to further improve ecological validity.

Physical reconstructions of head impacts are fundamental in understanding head injury biomechanics. While laboratory and computational experiments have been instrumental in this field, these techniques rely on many assumptions and require validation from real-world data. To address this, advancements in sensing technology has enabled inertial sensors to quantify head kinematics across various sporting domains. However, a prevalent issue with current wearable technology is the potential for significant errors in the captured kinematics. An often overlooked yet crucial cause of this disparity is sampling rate. If the sampling rate is too low, the peak value of an impact event may be missed. This study therefore aims to evaluate the average error in peak linear acceleration (PLA), peak angular velocity (PAV), and peak angular acceleration (PAA), associated with sampling rates across various impact scenarios; ultimately providing a resource to improve wearble sensor configuration.

description: Recent measurements of the cross sections for electronic state excitations in H2O have made it possible to calculate rates applicable to these excitation processes. We thus present here calculations of electron energy transfer rates for electronic and vibrational state excitations in H2O, as well as rates for excitation of some of these states by atmospheric thermal and auroral secondary electrons. The calculation of these latter rates is an important first step towards our aim of including water into a statistical equilibrium model of the atmosphere under auroral conditions.

description: We present a straightforward method for obtaining exact classical and quantum molecular Hamiltonians in terms of arbitrary coordinates. As compared to other approaches the resulting expression are rather compact, the physical meaning of each quantity is quite transparent, and in some cases the calculation effort will be greatly reduced. We also investigate systems with constrains to find the suggested method to be applicable in contrast to most conventional approaches to kinetic energy operators which cannot directly be applied to constrained systems. Two examples are discussed in detail, the monohydrated hydroxide anion and the protonated ammonia dimer.

Sex differences in the attentional networks: ERP components and behavioural indices
Creators: name: Hoysted, IHT
Publisher: name: University Of Tasmania
Year: 2023

description: Sex differences associated with attentional processes have been evidenced in the academic literature, however, the research is limited. The current study aimed to clarify the inconsistencies regarding sex differences in attentional processes examining behavioural performance (RT) and neuronal indices of attentional networks using event related potentials (ERPs). The participants, 13 females and 15 males (mean age of 22.1 years) completed an attentional network task (ANT) to examine sex differences in the alerting, orienting and executive control networks (P1, N1 and N2 ERP components). The ANT involved an alerting condition followed by a cueing condition which included a valid, invalid and no cue trial. The cue either correctly or incorrectly indicated the spatial location of a following target that was either congruent or incongruent. Males had a trend for faster RT for no cue and invalid trials as well as greater N1 amplitudes, indicating an overall orienting effect. Sex differences in the P1 and N2 ERP components, while preliminary, suggest that there may be sex differences associated with the electrophysiological activity of the attentional networks. Importantly, sex differences in the interaction between the three networks warrants further research and may help to explain the findings of the current study.

Children's morphological awareness: can the use of apostrophes and capital letters be improved through intervention?
Creators: name: Evans, JD
Publisher: name: University Of Tasmania
Year: 2023

description: The aim of this study was to determine whether a half-hour intervention could improve children's use of apostrophes or capitals, and whether this use was related to morphological awareness. Participants were 55 children in Grades 3 to 4 (24 males; M = 9.56 years, SD = 6.29). Results demonstrated that the intervention group significantly improved their use of plural possessives (e.g., trees'), but not singular possessives (e.g., tree's) or plurals (e.g., trees). The control group did not improve on any word type. Intervention was not successful for children learning to distinguish when to use or avoid capital letters (e.g., Turkey vs. turkey) with no improvement from either the intervention or control group. A follow-up pilot study of 19 children in Grades 5-6 (13 males; M = 11.44 years, SD = 9.04) demonstrated greater improvement, suggesting that a certain knowledge level is necessary for successful intervention. A second follow-up study of 26 adults (7 males; M = 30.54 years, SD = 15.51) indicated that while spellers did use capitals proficiently by adulthood, their use of apostrophes was far from perfect. Contrary to the hypothesis, no systematic patterns emerged between participants' morphological awareness and their ability to use apostrophes and capitals. Implications for future interventions and education are discussed.

description: Combining a recent derivation of the CMB evolution equations for homogeneous but anisotropic (Bianchi) cosmologies with an account of the full linearized dynamical freedoms available in such models, I calculate and discuss the various temperature and polarisation anisotropy patterns which may be formed. Certain anisotropies can be hidden in superhorizon modes at early times, thus avoiding any constraints from nucleosynthesis while nevertheless producing non-trivial redshift-zero temperature patterns in flat and open universes. The results are likely to be more of pedagogical than observational interest, but future work will assess whether such patterns can be matched to anomalies in WMAP results.

The targum (1970:Mar. 3 - 1970:Mar. 31)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1970

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

Traumatic brain injuries (TBIs) are a leading cause of death and disability worldwide. The availability of sensorized biofidelic head replicas, along with the corresponding validated finite element (FE) models, would provide a new tool for the experimental assessment of helmets effectiveness, in parallel to the detailed FE models of the human head. An instrumented human head replica (IHHR) was developed at the University of Padova in collaboration with Mid Sweden University. The inclusion of sensorised cerebrospinal fluidmeninges-brain simulants in the IHHR enables the assessment of brain damage by means of sensors embedded in the IHHR, thus improving the reproduction of injury mechanisms. The present work reports the development and preliminary validation of the numerical model of this replica, by means of unprotected drop tests on anvils.
Exploratory study of factors that influence parental adaptation during the autism spectrum disorder diagnostic process
Creators: name: de Deuge, JK
Publisher: name: University Of Tasmania
Year: 2023

description: Due to the complexity of diagnosing Autism Spectrum Disorder (ASD) a multidisciplinary diagnostic approach represents best practice quality care. This process can however be time consuming, with parents often facing long waiting periods which may complicate adaptation. The current research investigated the experiences of mothers who have had their child diagnosed through the multidisciplinary team at St Giles, Tasmania. Four mothers partook in semi-structured interviews, to describe their experience of the ASD diagnostic process. A qualitative approach was adopted and data analysed using thematic analysis. This investigation identified the issues that parents face throughout the three stages of the diagnostic process; pre-diagnosis, diagnosis and post diagnosis and the organisational factors that may positively influence how parents adapt to these issues. The results were fitted into a model showing that factors within the St Giles diagnostic process may interact to facilitate positive adaptation by influencing parent's social support and their perceptions of the situation or Sense of Coherence (SOC). This report provides a valuable insight into parental experiences of the diagnostic process and receiving a diagnosis of ASD. It also highlights the complexity of this process and, implications for further research and practice.
A Pulsed N.M.R. study of the ferromagnets Ni, Fe₂P and Fe₃P
Creators: name: Koster, Evert
Publisher: name: University of British Columbia
Year: 2011

description: The pulsed N.M.R. technique has been used to study the ferromagnets Ni, Fe₂P and Fe₃P. The dependence of the N.M.R. free induction decay on the strength of the applied r.f. field and on pulse length has been studied in nickel powder. The results indicate that the applied r.f. field is enhanced and that there is a distribution of enhancement factors. The distribution can be explained in the light of a model in which the domain walls vibrate like pinned membranes. The maximum enhancement factor is estimated to be 4700. The N.M.R. of ³¹P and ⁵⁷Fe has been observed in Fe₂P. Zero field resonances have been observed at the frequencies 17.5 MHz, 20.5 MHz, 77.5 MHz and 86.6 MHz at 1.5 K. These results allowed the deduction of the hyperfine fields at the various atomic sites. These are H[sub n] (FeI)=148 koe., H[sub n] (FeII)= 123 koe., H[sub n] (PI)=50.2 koe. and H[sub n] (PII)=45.0 koe.. From the shift of the N.M.R. frequency on application of an external magnetic field the sign of the phosphorous hyperfine fields is shown to be positive. The temperature dependence of the ³¹P N.M.R. frequency has also been studied and the data is well 2 fxtted by a T² law. Domain wall enhancement of the applied r.f. field was studied in the light of the pinned membrane model. Studies of the nuclear relaxation times indicate that thermal fluctuations of the domain walls provide the dominant relaxation mechanism. In Fe₃P a rather complicated N.M.R; spectrum was observed. Resonances occur at 41.7 MHz, 37.2 MHz, 34.5 MHz, 27.5 MHz and 24.8 MHz. These are all attributed to iron sites and correspond to hyperfine fields of 304 koe., 271 koe., 200 koe., and 180. koe. . Domain wall enhancements were also studied in the light of the pinned membrane model. Nuclear relaxation times were also determined and the results indicate that thermal fluctuations of the domain walls provide the dominant relaxation mechanism.

description: The motivation, techniques and performance of the ground-based photometric follow-up of transit detections by the CoRoT space mission are presented. Its principal raison d'être arises from the much higher spatial resolution of common ground-based telescopes in comparison to CoRoT's cameras. This allows the identification of many transit candidates as arising from eclipsing binaries that are contaminating CoRoT's lightcurves, even in low-amplitude transit events that cannot be detected with ground-based obervations. For the ground observations, 'on'-'off' photometry is now largely employed, in which only a short timeseries during a transit and a section outside a transit is observed and compared photometrically. CoRoT planet candidates' transits are being observed by a dedicated team with access to telescopes with sizes ranging from 0.2 to 2 m. As an example, the process that led to the rejection of contaminating eclipsing binaries near the host star of the Super-Earth planet CoRoT-7b is shown. Experiences and techniques from this work may also be useful for other transit-detection experiments, when the discovery instrument obtains data with a relatively low angular resolution.

description: A survey of Type II supernovae explosion models has been carried out to determine how their light curves and spectra vary with their mass, metallicity, and explosion energy. The presupernova models are taken from a recent survey of massive stellar evolution at solar metallicity supplemented by new calculations at subsolar metallicity. Explosions are simulated by the motion of a piston near the edge of the iron core and the resulting light curves and spectra are calculated using full multi-wavelength radiation transport. Formulae are developed that describe approximately how the model observables (light curve luminosity and duration) scale with the progenitor mass, explosion energy, and radioactive nucleosynthesis. Comparison with observational data shows that the explosion energy of typical supernovae (as measured by kinetic energy at infinity) varies by nearly an order of magnitude -- from 0.5 to 4.0 x 10^51 ergs, with a typical value of ~0.9 x 10^51 ergs. Despite the large variation, the models exhibit a tight relationship between luminosity and expansion velocity, similar to that previously employed empirically to make SNe IIP standardized candles. This relation is explained by the simple behavior of hydrogen recombination in the supernova envelope, but we find a sensitivity to progenitor metallicity and mass that could lead to systematic errors. Additional correlations between light curve luminosity, duration, and color might enable the use of SNe IIP to obtain distances accurate to ~20% using only photometric data.

In 2016, Wells Fargo admitted that employees had opened as many as 2 million accounts without customer authorization over a five-year period. We discuss the factors that contributed to the scandal, the repercussions for the bank, and its response. We ask: How did the company’s incentive system contribute to the scandal? Would the system have worked better if coupled with additional metrics or controls? What systems should have been put in place to identify and escalate potential problems earlier? What steps should senior management have taken to better contain the fallout? Is an inside or outside CEO successor better positioned to help the bank recover? How do you maximize the positive contribution that incentives make to culture while minimizing potentially negative outcomes?

description: We investigate the spectrum and eigenstates of a Bose-Hubbard chain containing two bosons with fixed boundary conditions. In the noninteracting case the eigenstates of the system define a two-dimensional normal-mode space. For the interacting case weight functions of the eigenstates are computed by perturbation theory and numerical diagonalization. We identify paths in the two-dimensional normal-mode space which are rims for the weight functions. The decay along and off the rims is algebraic. Intersection of two paths (rims) leads to a local enhancement of the weight functions. We analyze nonperturbative effects due to the degeneracies and the formation of two-boson bound states.

description: Over the last decades, aquaculture production increased rapidly. The future development of the industry highly relies on the sustainable utilization of natural resources. The need for improving disease resistance, growth performance, food conversion, and product safety for human consumption has stimulated the application of probiotics in aquaculture. Probiotics increase growth and feed conversion, improve health status, raise disease resistance, decrease stress susceptibility, and improve general vigor. Currently, most probiotics still originate from terrestrial sources rather than fish. However, host-associated (autochthonous) probiotics are likely more persistent in the gastrointestinal tract of fish and may, therefore, exhibit longer-lasting effects on the host. Probiotic candidates are commonly screened in in vitro assays, but the transfer to in vivo assessment is often problematic. In conclusion, modulation of the host-associated microbiome by the use of complex probiotics is promising, but a solid understanding of the interactions involved is only in its infancy and requires further research. Probiotics could be used to explore novel ingredients such as chitin-rich insect meal, which cannot be digested by the fish host alone. Most importantly, probiotics offer the opportunity to improve stress and disease resistance, which is among the most pressing problems in aquaculture.
The effects of cravings on metacognition
Creators: name: Riza, JL
Publisher: name: University Of Tasmania
Year: 2023

description: This study used a sample (N = 68) of regular coffee drinkers to investigate how cravings may influence JOLs when completing a cue-only word pair task. Two groups: a craving and a control group were randomly allocated where cravers had to avoid consuming coffee before testing. Both groups completed a word pair encoding task followed by completing either a craving induction task if they had abstained from coffee or a control task if they had not. Both groups then made cue-only JOLs and a subsequent retrieval attempt on the target. Craving strength was measured at the end of the experiment. Results indicated that JOLs for cravers were less realistic which may have been due to the presence of cravings.
Enhancements observed in the scattered light spectra of a carbon arc plasma

Publisher: name: University of British Columbia
Year: 2011

description: The spectrum of Ruby laser light scattered from a carbon arc plasma has been studied. The temperature of the plasma is shown to be much hotter than was previously reported. Enhancements in the spectrum of light scattered were observed. Their frequencies were shown to be a sensitive function of the plasma wave scale length K, and the plasma density and temperature. A model is constructed which produces enhancements in the theoretical scattered spectra at particular frequencies. This model is fitted to the observed spectra; this fitting is discussed.

description: Probiotic bacteria are a recognized alternative to classical methods of disease prophylaxis and therapy. We tested the effects of their application on the immune reaction in juvenile turbot. To prevent digestion of the probiotics, rectal administration was applied to maximise colonization, by-passing digestion in the stomach. The application of Psychrobacter nivimaris and Psychrobacter faecalis showed beneficial effects on the inflammatory response and disease resistance after infection with the common pathogen Tenacibaculum maritimum. Treatment with P. nivimaris and P. faecalis resulted in 0% and 8% mortalities post-infection, while in the treatment control, an elevated mortality of 20% was observed. In the challenge controls (no infection), no mortalities were observed during the entire experimental period. After an experimental infection, mRNA expression of selected immune markers (mhc II α, il-1β, tcr, tgf β and tnf α) were determined by RT-QPCR at 0, 1 and 5 days post-infection (dpi). At 0 dpi, gene expression was comparable between the treatments and the treatment control, suggesting that probiotics did not act via immune stimulation of the host. At 1 dpi, all genes were up-regulated in the treatment control but not in the probiotic groups, indicating that the infection in probiotic-treated fish developed at a less severe level. At 5 dpi, mRNA expression returned to baseline levels. As a conclusion, the native probiotic candidates P. nivimaris and P. faecalis improved survival, whereas, in the control, mortality increased and expression of the immune markers was up-regulated post infection. This highlights a potential application of P. nivimaris and P. faecalis in disease prophylaxis, but further research is needed.

description: This paper highlights methods for using geospatial analysis to assess, enhance, and improve recruitment efforts to ensure representativeness in study populations. We apply these methods to the Measurement to Understand Reclassification of Disease of Cabarrus/Kannapolis (MURDOCK) study, a longitudinal population health study focused on the city of Kannapolis and Cabarrus County, NC. Although efforts have been made to recruit a participant registry that is representative of the 18 ZIP code catchment region inclusive of Cabarrus County and Kannapolis, bias in such recruitment is inevitable. Participants in the MURDOCK study are geospatially referenced at entry, providing information that can be used to monitor and guide recruitment efforts. MURDOCK participant population representativeness was assessed using chi-squared tests to compare the MURDOCK population with 2010 Census data, relative to both the entire 18 ZIP code catchment area and for individual Census tracts. A logistic regression model was fit to characterize Census tracts with low recruitment, defined by fewer than 56 participants from that tract. The distance to the site at which participants enrolled was calculated, and median distance to enrollment site was used in the logistic regression. Tracts with low recruitment rates contained higher minority and younger populations, suggesting specific strategies for improving recruitment in these areas. Areal units farther away from enrollment sites were also not well-sampled, despite being in the specified study area, indicating that distance traveled to enrollment may be a barrier. These results have implications for targeting recruitment efforts and representative samples more generally, including in other population-based studies.

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We study relativistically expanding electromagnetic fields of cylindrical geometry. The fields emerge from the side surface of a cylinder and are invariant under translations parallel to the axis of the cylinder. The expansion velocity is in the radial direction and is parametrized by $v=R/(ct)$. We consider force-free magnetic fields by setting the total force the electromagnetic field exerts on the charges and the currents equal to zero. Analytical and semi-analytical separable solutions are found for the relativistic problem. In the non-relativistic limit the mathematical form of the equations is similar to equations that have already been studied in static systems of the same geometry.

description: Stellar masses play a crucial role in the exploration of galaxy properties and the evolution of the galaxy population. In this paper, we explore the minimum possible uncertainties in stellar mass-to-light (M/L) ratios from the assumed star formation history (SFH) and metallicity distribution, with the goals of providing a minimum set of requirements for observational studies. We use a large Monte Carlo library of SFHs to study as a function of galaxy spectral type and signal-to-noise ratio (S/N) the statistical uncertainties of M/L values using either absorption-line data or broad band colors. The accuracy of M/L estimates can be significantly improved by using metal-sensitive indices in combination with age-sensitive indices, in particular for galaxies with intermediate-age or young stellar populations. While M/L accuracy clearly depends on the spectral S/N ratio, there is no significant gain in improving the S/N much above 50/pix and limiting uncertainties of 0.03 dex are reached. Assuming that dust is accurately corrected or absent and that the redshift is known, color-based M/L estimates are only slightly more uncertain than spectroscopic estimates (at comparable spectroscopic and photometric quality), but are more easily affected by systematic biases. This is the case in particular for galaxies with bursty SFHs (high Hdelta at fixed D4000), the M/L of which cannot be constrained any better than 0.15 dex with any indicators explored here. Finally, we explore the effects of the assumed prior distribution in SFHs and metallicity, finding them to be higher for color-based estimates.

An efficient algorithm for computing the Baker-Campbell-Hausdorff series and some of its applications

description: We provide a new algorithm for generating the Baker--Campbell--Hausdorff (BCH) series $Z = \log(\e^X \e^Y)$ in an arbitrary generalized Hall basis of the free Lie algebra $\mathcal{L}(X,Y)$ generated by $X$ and $Y$. It is based on the close relationship of $\mathcal{L}(X,Y)$ with a Lie algebraic structure of labeled rooted trees. With this algorithm, the computation of the BCH series up to degree 20 (111013 independent elements in $\mathcal{L}(X,Y)$) takes less than 15 minutes on a personal computer and requires 1.5 GBytes of memory. We also address the issue of the convergence of the series, providing an optimal convergence domain when $X$ and $Y$ are real or complex matrices.

description: It is widely accepted that the onset of the explosive carbon burning in the core of a CO WD triggers the ignition of a SN Ia. The features of the ignition are among the few free parameters of the SN Ia explosion theory. We explore the role for the ignition process of two different issues: firstly, the ignition is studied in WD models coming from different accretion histories. Secondly, we estimate how a different reaction rate for C-burning can affect the ignition. Two-dimensional hydrodynamical simulations of temperature perturbations in the WD core ("bubbles") are performed with the FLASH code. In order to evaluate the impact of the C-burning reaction rate on the WD model, the evolution code FLASH_THE_TORTOISE from Lesaffre et al. (2006) is used. In different WD models a key role is played by the different gravitational acceleration in the progenitor's core. As a consequence, the ignition is disfavored at a large distance from the WD center in models with a larger central density, resulting from the evolution of initially more massive progenitors. Changes in the C reaction rate at T < 5e8 K slightly influence the ignition density in the WD core, while the ignition temperature is almost unaffected. Recent measurements of new resonances in the C-burning reaction rate (Spillane et al. 2007) do not affect the core conditions of the WD significantly. This simple analysis, performed on the features of the temperature perturbations in the WD core, should be extended in the framework of the state-of-the-art numerical tools for studying the turbulent convection and ignition in the WD core. Future measurements of the C-burning reactions cross section at low energy, though certainly useful, are not expected to affect dramatically our current understanding of the ignition process.

description: We prove that every entangled state is useful as a resource for the problem of minimum-error channel discrimination. More specifically, given a single copy of an arbitrary bipartite entangled state, it holds that there is an instance of a quantum channel discrimination task for which this state allows for a correct discrimination with strictly higher probability than every separable state.

description: The boards of all publicly traded companies are required to conduct a self-evaluation at least annually to determine whether they are functioning effectively. Research suggests that while many directors are satisfied with the job that they and their fellow board members do, board evaluations and boardroom performance fall short along several important dimensions. We review the current state of board evaluations, and summarize how they can improve. We ask: Why do board evaluations fail to review the performance individual directors? What are the social and psychological barriers to conducting effective evaluations, and how can they be reduced? What behaviors are required to be successful in a boardroom setting? How important is boardroom culture, and how does it influence decision making?
