Li Cunxin, author of Mao's Last Dancer and Artistic Director, Queensland Ballet. The iconic ballet Swan Lake, the tragic love story of a princess transformed into a swan by an evil sorcerer, has been revered for more than a century. In this atmospheric adaptation, Anne Spudvilas reimagines the classic tale of passion, betrayal and heartbreak in the dramatic riverscape of the Murray-Darlin
From crystal to adsorption : new insights into layered double hydroxides derived sorbent materials for carbon capture
No full textWith the goal of designing mixed metal oxides (MMOs) that have better CO2 sorption
performance, such as sorption capacities greater than 1.35 mmol/g at the intermediate
temperature range (200 – 400 ˚C), detailed investigation was performance on the MMOs
and their precursor, layered double hydroxides (LDHs). The novelty of work lies in the
crystal chemistry approach, which uses the crystal lattice parameter “a” of precursors
LDHs to obtain the “true” chemical composition of sorbent material. Two systematic
studies based on this approach were conducted to study the effects of different variables on
the CO2 adsorption performance of resultant MMOs, e.g., xcrystal of LDH phase, synthesis
methods and choice of precursors. Synthesis methods was found to be the most important
variable affecting the properties of LDHs and MMOs phase; and co-precipitation method
produces LDH-derived MMOs sorbent with the more desirable CO2 capture performance,
compared to the urea hydrolysis method. The results obtained from these systematic studies
allow the establishment of a new crystal-chemical model for Mg-Al based LDHs that is
fundamentally sound and more accurate when obtaining x from a. Finally, unambiguous
characterization of the equilibrium isotherms and diffusion coefficient of pristine Mg-Al
MMOs was conducted for the intermediate temperature range, using gravimetric and zero
length column method. In the low-pressure region (< 8 bar) and 200 ˚C, the equilibrium
capacities and diffusional coefficient values of pristine MMOs are found comparable to
those promoted with alkali metal salts (AMS). However, in the high-pressure region (8 - 30
bar) and temperature range between 300 – 400 ˚C, the AMS-promoted MMOs shows
almost a two-fold increase in the equilibrium capacities. Overall, the present work set a
reference case for the CO2 adsorption performance of LDH-derived MMOs
In situ δ7Li, Li/Ca, and Mg/Ca analyses of synthetic aragonites

The definitive version was published in Geochemistry Geophysics Geosystems 12 (2011): Q03001, doi:10.1029/2010GC003322.In situ secondary ion mass spectrometry (SIMS) analyses of δ7Li, Li/Ca, and Mg/Ca were performed on five synthetic aragonite samples precipitated from seawater at 25°C at different rates. The compositions of δ7Li in bulk aragonites and experimental fluids were measured by multicollector inductively coupled plasma–mass spectrometry (MC-ICP-MS). Both techniques yielded similar δ7Li in aragonite when SIMS analyses were corrected to calcium carbonate reference materials. Fractionation factors α7Li/6Li range from 0.9895 to 0.9923, which translates to a fractionation between aragonite and fluid from −10.5‰ to −7.7‰. The within-sample δ7Li range determined by SIMS is up to 27‰, exceeding the difference between bulk δ7Li analyses of different aragonite precipitates. Moreover, the centers of aragonite hemispherical bundles (spherulites) are enriched in Li/Ca and Mg/Ca relative to spherulite fibers by up to factors of 2 and 8, respectively. The Li/Ca and Mg/Ca ratios of spherulite fibers increase with aragonite precipitation rate. These results suggest that precipitation rate is a potentially important consideration when using Li isotopes and elemental ratios in natural carbonates as a proxy for seawater composition and temperature.SIMS analyses were supported by U.S. NSF, EAR, Instrumentation and Facilities Program.

How many focus markers are there in Konkomba?
No full textThis article discusses the divergent status of the two particles lé and lá in the grammar of Konkomba, a Gur language (Niger-Congo) of the Gurma subgroup. While previous studies claim that both particles are focus markers, this author argues that only the particle lá should be analyzed as a pure pragmatic device. Distributional studies suggest that the use of particle lé, on the other hand, is only required under specific focus conditions, and primarily represents a syntactic device
Identification of heart rate-associated loci and their effects on cardiac conduction and rhythm disorders
No full textElevated resting heart rate is associated with greater risk of cardiovascular disease and mortality. In a 2-stage meta-analysis of genome-wide association studies in up to 181,171 individuals, we identified 14 new loci associated with heart rate and confirmed associations with all 7 previously established loci. Experimental downregulation of gene expression in Drosophila melanogaster and Danio rerio identified 20 genes at 11 loci that are relevant for heart rate regulation and highlight a role for genes involved in signal transmission, embryonic cardiac development and the pathophysiology of dilated cardiomyopathy, congenital heart failure and/or sudden cardiac death. In addition, genetic susceptibility to increased heart rate is associated with altered cardiac conduction and reduced risk of sick sinus syndrome, and both heart rate-increasing and heart rate-decreasing variants associate with risk of atrial fibrillation. Our findings provide fresh insights into the mechanisms regulating heart rate and identify new therapeutic targets

Getting in the path of the robot: Pedestrians acceptance of crossing roads near fully automated vehicles
No full textAdoption of Automated Vehicles (AVs) within transport networks relies on the technology acceptance of not only AV users, but also other road users such as pedestrians. However, previous research has mostly focused on user acceptance of AVs and the receptivity of pedestrians towards AVs has been largely unexplored. This study aims to fill this gap by applying the Theory of Planned Behaviour (TPB), the Technology Acceptance Model (TAM), and the Unified Theory of Acceptance and Use of Technology (UTAUT) to investigate pedestrians’ intentions to cross a road in front of a fully AV. To achieve this goal, a 20-minute online questionnaire was administered in Australia and data were collected from a total of 485 participants (average age = 35.35 years, 51.5% female). Bivariate correlation analysis and hierarchical regression models were then applied on the data to investigate the association between pedestrian attributes and their behavioural intentions. The findings revealed that the TPB and the UTAUT explained 46% and 43% of the variance in intentions to cross a road in front of a fully AV, respectively, with perceived behavioural control (PBC) and subjective/social norms the most significant unique predictors of intentions within the TPB and UTAUT, respectively. The TAM, however, only explained 35% of the variance in intentions to cross a road in front of a fully AV. When added into Step 2 of the hierarchical regression, age accounted for additional variance above the TAM predictors, indicating that younger participants reported higher intentions to cross a road in front of a fully AV than older participants. Age was not a significant predictor of intentions when entered with the predictors of the TPB and UTAUT. This study provides support for the use of these theoretical models to understand pedestrians’ acceptance of AVs.Accepted Author ManuscriptSafety and Security Scienc
EXAMINATION OF HCO--X AND NHCHCOOH--X COMPLEXES [X = Li, Na, K] USING ELECTRONIC STRUCTURE THEORY
No full textAuthor Institution: Department of Chemistry, The Ohio State University, Columbus, OH 43210Infrared spectroscopy is a powerful tool for studying molecular structure as changes in the frequency and intensity of infrared transitions provide a way to probe environment effects on molecular systems. In this study we investigate how the frequency and intensity of the C=O stretch vibration of formaldehyde and glycine change upon the introduction of alkali metal cations. Specifically we focus on the complexes of Li, Na, and K with HCO and NHCHCOOH. There is evidence of small changes in the harmonic C=O stretch frequency; however, the changes in intensity are much larger. For example the intensity of the C=O stretch in HCO--Li is twice that in bare HCO. The ultimate goal of this work is to determine how the sensitivity of the C=O stretch vibration is affected by the particular alkali metal cation as well as the geometry of the complex. All calculations in this study were performed using Gaussian03 at the MP2/6-311G level of theory/basis set
