Test of Ideational Praxis (TIP): Preliminary Findings and Interrater and Test–Retest Reliability With Preschoolers
Authors: Lane Shelly J. , Ivey Carole K. , May-Benson Teresa A. 
Published: September 2014

AbstractPraxis is the ability of the brain to develop an idea for action and plan, organize, and execute unfamiliar motor actions. It enables purposeful interaction with people and things in the environment. Ideation is central to praxis but has been little researched. This study investigated the reliability of the Test of Ideational Praxis (TIP) and examined ideational praxis in typical preschoolers. TIP performance for 78 preschoolers ages 3, 4, and 5 yr was videotaped and scored by two trained raters. The TIP has strong interrater reliability, supporting earlier findings. Further, we documented test–retest stability over 2 wk. As a group, preschoolers identified 10.6 affordances (ideas) for action on the TIP; no age differences were found. Training is required for accurate scoring of the TIP; following training, clinicians and researchers may find the TIP a useful tool to screen motor ideational abilities in young children.

Pn anisotropy beneath the South Island of New Zealand and implications for distributed deformation in continental lithosphere
Authors: Collins John A. , Molnar Peter 
Published: September 2014

AbstractPn travel times from regional earthquakes recorded both by stations on New Zealand and by ocean bottom seismographs deployed offshore indicate anisotropy in the uppermost mantle beneath the region. The largest anisotropy of ~8% (±2%, 1σ) lies beneath the deforming part of the South Island to just off its West Coast, a zone roughly 100–200 km wide. The fastest propagation is aligned N60°E (±3°), essentially parallel to the largely strike‐slip relative plate motion since 20 Ma, also ~ N60°E. The magnitude of anisotropy decreases abruptly northwest and southeast of this zone, and on the southeast side of the island, the orientation of fastest propagation is between N32°W and N‐S. The ~ N60°E orientation of fast propagation is consistent with finite strain within the uppermost part of the mantle lithosphere if the measured 850 km of displacement of the Pacific plate past the Australia plate is spread over a region with a width of 100–200 km. The agreement of this orientation of fast propagation with the orientation or relative plate motion suggests the possibility of but does not require some dynamic recrystallization in rock as cold as 500–800°C, where Peierls creep seems to be the likely deformation mechanism. Such a strain distribution matches deformation of a thin viscous sheet that obeys a constitutive relationship of the form , where is the average strain rate and τ is the operative deviatoric stress, with an average value of n ≈ 3–10. Presumably, the NW‐SE fast propagation in the region southeast of the island results from strain that precedes the Cenozoic deformation that has shaped the island.
Intrusion of Rhone River diluted water into the Bay of Marseille: Generation processes and impacts on ecosystem functioning

Published: September 2014

AbstractThe Rhone River provides the largest inputs of terrestrial freshwater and nutrients into the Mediterranean Sea. The Rhone River diluted water intrusions into the Bay of Marseille were investigated, examining their physical generation processes and associated biogeochemical impact by using in situ observations, remote sensing data, and a three‐dimensional physical/biogeochemical coupled model. During our study period from 2007 to 2011, Rhone River intrusions occurred on average 7.6 times per year and affected more frequently the northern part of the bay. A classification of intrusion events in three categories is proposed (short lived, big, and small) as a function of their duration and spatial extent. The intrusions appeared to be driven by: (i) wind forcing, (ii) the presence of a mesoscale eddy, (iii) the Rhone River discharge volume, and (iv) the variation in thermocline depth. Typically, a combination of these favorable factors was necessary to induce an intrusion. An intrusion strongly impacts the biogeochemical functioning of the Bay of Marseille by bringing large quantities of nutrients into the bay. Mass balances were computed allowing us to quantify this impact on the Bay of Marseille. The results show that the ecological impact depends very much on the type of intrusion, with big intrusions having the highest impact.
OH Meinel band nightglow profiles from OSIRIS observations

Published: September 2014

AbstractThe mesospheric nightglow spectrum is replete with OH Meinel band emissions, from the midvisible to the midinfrared. These emissions provide a wealth of aeronomic information, giving a physical view of the chemistry and dynamics of the upper atmosphere. The Optical Spectrograph and Infrared Imaging System (OSIRIS) instrument, on the Odin satellite, is currently one of the few satellite instruments that simultaneously observes emissions from multiple and separate Meinel bands. This has allowed the derivation of near‐global data sets of nighttime OH volume emission rate profiles for the Meinel (5‐1), (8‐3), and (9‐4) bands. The 2002–2013 climatologies consistently show that emission from bands in higher upper vibrational levels peaks at higher altitudes. The global average (5‐1), (8‐3), and (9‐4) band emission peak heights are at altitudes of 86.0 km, 86.7 km, and 87.1 km, respectively. The 1σ variation in the (5‐1), (8‐3), and (9‐4) band, peak heights are 1.8 km, 1.9 km, and 1.9 km, respectively. The climatological (30 day, 10° latitude) peak heights can vary significantly with both time and latitude; however, the (5‐1) band climatological peak height is nearly always below that of the (8‐3) band, which is nearly always below that of the (9‐4) band. The temporal variation in the emission peak height can have a significant impact on measurements of OH rotational temperatures from ground‐based observations of the OH layer. It was found that omitting the profile climatology can bias a ground‐based temperature measurement by as much as ±4 K and can also make ground‐based measurements susceptible to nonrealistic temperature variations.
Exploring landscape sensitivity to the Pacific Trade Wind Inversion on the subsiding island of Hawaii
Authors: Ward Dylan J. , Galewsky Joseph 
Published: September 2014

AbstractThe interaction of the subsiding limb of the Hadley circulation and the easterly North Pacific Trade Winds establishes a persistent thermal inversion at about 2000 m above sea level in the subtropical Pacific. The inversion restricts convective rainfall to the lower elevations of the windward flank of the island of Hawaii, creating an order‐of‐magnitude vertical rainfall gradient, as well as high interbasin variability in precipitation. In the high‐rainfall zone, streams are incised tens to hundreds of meters below the surface of the volcanic shield. We use a digital elevation model and 1‐D numerical modeling to assess whether deep incision on the flank of Mauna Kea is tied to the elevation of the trade wind inversion. The 83 channels examined can be well fit in aggregate by all models that account for differences in precipitation between basins; specifically, the maximum depth of incision in each drainage is a power function of precipitation‐weighted drainage area with an exponent of ~ ½. Individual longitudinal stream profiles are generally better fit by models that acknowledge both along‐channel precipitation variability and the subsidence of the island through that gradient, but this relationship is not clearly demonstrable for many channels. We argue that island subsidence through the dry‐to‐wet precipitation gradient has resulted in less cumulative discharge in the lower reaches of the drainages over their lifetime, relative to a nonsubsiding case. This reduces differential erosion between the wet and dry reaches by 20–30% over 300 kyr, making the longitudinal profiles less sensitive to the very strong climate gradient.
Mg/Ca composition of benthic foraminifera Miliolacea as a new tool of paleoceanography

Published: September 2014

AbstractThe Mg/Ca compositions of benthic foraminifera from the superfamily Miliolacea have been studied to explore the use of these high‐Mg foraminifera as a proxy for deep ocean conditions. Taxonomic analyses, relative abundance, and depth distributions of different Miliolacea species were carried out on a collection of core top samples, covering a depth range of 131 m to 2530 m, along the Australian coast of the Timor Sea. Pyrgo sp., composed of Pyrgo sarsi and Pyrgo murrhina, was found to be the most suitable for proxy studies. Mg/Ca values of this group of foraminifera show a strong correlation with bottom water temperatures and carbonate ion saturation described by the linear relationship: Mg/Ca = 2.53(±0.22) × BWT + 0.129(±0.023) × Δ[CO32−] + 4.63(±0.53), within the −1°C to 8°C temperature range. Absolute Mg/Ca values of Pyrgo sp. calcite and their temperature sensitivity are similar to those observed for inorganic calcite, suggesting that Mg composition of Pyrgo sp. calcite is mainly controlled by inorganic processes. The Mg/Ca composition of Pyrgo sp. calcite provides a new tool for reconstructing both water temperature and carbonate ion saturation when combined with other proxies for one of these parameters. A down core record from the Eastern Equatorial Pacific has been generated to illustrate how Mg/Ca values can be used for paleoclimate studies. This down core record shows large changes in Pacific bottom waters [CO32−] across glacial‐interglacial transition, implying an increase in [CO32−] during the glacial period.

BackgroundOdontogenic sinusitis and “sinonasal complications of dental disease or dental treatment” (SCDDT) have been assumed to be limited to the maxillary sinus. Nevertheless, many patients also show more extensive sinonasal involvement and, occasionally, also have associated bilateral disease. We evaluated the incidence of extramaxillary extension over an 11‐year period in our clinic.MethodsWe retrospectively evaluated 315 surgically treated SCDDT patients. Sinonasal involvement was assessed with presurgical imaging and confirmed with intraoperative findings. Patients were subsequently categorized into 3 groups, based on the sinonasal extension.ResultsIn 40.3% of patients the sinonasal condition was limited to the maxillary sinus. Forty‐one percent of patients had unilateral extramaxillary involvement, and in 18.7% of patients, we found bilateral involvement.ConclusionComplete presurgery evaluation with endoscopy and a computed tomography (CT) scan in SCDDT patients is essential. SCDDT patients not responding to medical and dental treatment should be addressed with a planned approach targeting the extramaxillary extension, which may necessitate a combined oral and endonasal approach. It is unclear whether disease in the maxillary sinus contralateral to the primary maxillary sinus demonstrating odontogenic‐induced disease is incidental, associated, or represents a subclinical odontogenic infection.

AbstractPhosphor fasziniert durch seine strukturelle Vielfalt und erregt nach wie vor Aufsehen durch die Entdeckung neuer Modifikationen. Diese Arbeit beschreibt erstmals eine komplette Stabilitätsreihe bekannter und neuer kristalliner Phosphorallotrope. Darin enthalten sind die jüngst beschriebenen tubulären Modifikationen und Vorhersagen zu den bislang unbekannten festen Strukturen der [P12]‐ und der noch nicht isolierten [P14]‐Nanostäbe. Trotz signifikanter struktureller Unterschiede handelt es sich bei allen P‐Allotropen um kovalente Teilstrukturen, die durch Van‐der‐Waals(vdW)‐Wechselwirkungen zusammengehalten werden. Diese durch Rechnungen korrekt wiederzugeben, ist ein Kernpunkt aktueller Forschung. Während die etablierten DFT‐Funktionale GGA und LDA bei der Beschreibung der P‐Allotrope teilweise erheblich von experimentellen Werten abweichen, können mit dem hier verwendeten Korrekturterm (GGA‐D2) durchgehend hervorragende Übereinstimmungen mit dem Experiment und Vorhersagen zu den festen Strukturen der P‐Nanostäbe erreicht werden.
Separating Para and Ortho Water
Authors: Horke Daniel A. , Chang Yuan‐Pin , Długołęcki Karol , Küpper Jochen 
Published: September 2014

AbstractWater exists as two nuclear‐spin isomers, para and ortho, determined by the overall spin of its two hydrogen nuclei. For isolated water molecules, the conversion between these isomers is forbidden and they act as different molecular species. Yet, these species are not readily separated, and no pure para sample has been produced. Accordingly, little is known about their specific physical and chemical properties, conversion mechanisms, or interactions. The production of isolated samples of both spin isomers is demonstrated in pure beams of para and ortho water in their respective absolute ground state. These single‐quantum‐state samples are ideal targets for unraveling spin‐conversion mechanisms, for precision spectroscopy and fundamental symmetry‐breaking studies, and for spin‐enhanced applications, for example laboratory astrophysics and astrochemistry or hypersensitized NMR experiments.

AbstractQuantitation of lipid storage, unsaturation, and oxidation in live C. elegans has been a long‐standing obstacle. The combination of hyperspectral stimulated Raman scattering imaging and multivariate analysis in the fingerprint vibration region represents a platform that allows the quantitative mapping of fat distribution, degree of fat unsaturation, lipid oxidation, and cholesterol storage in vivo in the whole worm. Our results reveal for the first time that lysosome‐related organelles in intestinal cells are sites for storage of cholesterol in C. elegans.
High‐Resolution Spectroscopy of the Chiral Metal Complex [CpRe(CH3)(CO)(NO)]: A Potential Candidate for Probing Parity Violation
Authors: Medcraft Chris , Wolf Robert , Schnell Melanie 
Published: September 2014

AbstractHeavy‐metal containing chiral compounds have been suggested as promising candidates for studying parity‐violation effects. We report herein the broadband rotational spectroscopy study of the chiral complex [CpRe(CH3)(CO)(NO)] in the gas phase. The spectra obtained are very rich due to the two rhenium isotopologues (185Re and 187Re), hyperfine structure arising from the rhenium and nitrogen nuclei, and the asymmetry of the chiral complex. Since rhenium is located very close to the molecular center of mass, the rotational constants for the two rhenium isotopologues are very similar. However they can be differentiated by their characteristic nuclear quadrupole hyperfine splitting patterns. Comparison with calculated nuclear quadrupole coupling constants shows that all‐electron relativistic basis sets are necessary for a correct description of the rhenium atom in this type of complex. The present study is an important step towards future precision studies on chiral molecules.
N‐Methylacridinium Salts: Carbon Lewis Acids in Frustrated Lewis Pairs for σ‐Bond Activation and Catalytic Reductions
Authors: Clark Ewan R. , Ingleson Michael J. 
Published: September 2014

AbstractN‐methylacridinium salts are Lewis acids with high hydride ion affinity but low oxophilicity. The cation forms a Lewis adduct with 4‐(N,N‐dimethylamino)pyridine but a frustrated Lewis pair (FLP) with the weaker base 2,6‐lutidine which activates H2, even in the presence of H2O. Anion effects dominate reactivity, with both solubility and rate of H2 cleavage showing marked anion dependency. With the optimal anion, a N‐methylacridinium salt catalyzes the reductive transfer hydrogenation and hydrosilylation of aldimines through amine–boranes and silanes, respectively. Furthermore, the same salt is active for the catalytic dehydrosilylation of alcohols (primary, secondary, tertiary, and ArOH) by silanes with no observable over‐reduction to the alkanes.
Watson–Crick Base Pairing Controls Excited‐State Decay in Natural DNA

Published: September 2014

AbstractExcited‐state dynamics are essential to understanding the formation of DNA lesions induced by UV light. By using femtosecond IR spectroscopy, it was possible to determine the lifetimes of the excited states of all four bases in the double‐stranded environment of natural DNA. After UV excitation of the DNA duplex, we detected a concerted decay of base pairs connected by Watson–Crick hydrogen bonds. A comparison of single‐ and double‐stranded DNA showed that the reactive charge‐transfer states formed in the single strands are suppressed by base pairing in the duplex. The strong influence of the Watson–Crick hydrogen bonds indicates that proton transfer opens an efficient decay path in the duplex that prohibits the formation or reduces the lifetime of reactive charge‐transfer states.

Published: September 2014

AbstractWith the ongoing developments in biomass conversion, the oxidation of bioethanol to acetaldehyde may become a favorable and green alternative to the preparation from ethylene. Here, a simple and effective method to encapsulate gold nanoparticles in zeolite silicalite‐1 is reported and their high activity and selectivity for the catalytic gas‐phase oxidation of ethanol are demonstrated. The zeolites are modified by a recrystallization process, which creates intraparticle voids and mesopores that facilitate the formation of small and disperse nanoparticles upon simple impregnation. The individual zeolite crystals comprise a broad range of mesopores and contain up to several hundred gold nanoparticles with a diameter of 2–3 nm that are distributed inside the zeolites rather than on the outer surface. The encapsulated nanoparticles have good stability and result in 50 % conversion of ethanol with 98 % selectivity toward acetaldehyde at 200 °C, which (under the given reaction conditions) corresponds to 606 mol acetaldehyde/mol Au hour−1.
