The Structural Foundations of the Northern Carnarvon Basin

In 1991-92, the Australian Geological Survey Organisation (AGSO) acquired approximately 4500 km of deep-seismic data over the northern Carnarvon Basin on the North West Shelf. These data image basin-forming events down to depths of 10-12 seconds (15-30 km) and allow an interpretation of the foundations of structures that host numerous hydrocarbon accumulations. The northern Carnarvon Basin is a major sag basin that has accumulated at least 12-15 km of sediment fill since its initiation, probably in the Carboniferous. The Palaeozoic and Mesozoic sedimentary fill has a 'layer(cid:8226) cake' appearance and has been subjected to multiple episodes of faulting, folding, and inversion, especially in the Late Triassic, Jurassic, and Cretaceous. There is little evidence of extension during the Mesozoic; transpressional and transtensional movements appear to be predominant. The only significant disruption to the 'layer-cake' appearance occurs beneath the inner part of the basin, where a major landwards-soling fault system cleaves the basin from Upper Triassic level through to at least the base of the crust. This fault system (the 'Rankin Fault System') extends for more than 500 km along the southeast flank of the basin and, with its antithetic fault system, has served to focus the deposition of major clastic sequences during the Jurassic and Cretaceous. Integration of the deep-seismic data with limited velocity information from the Exmouth Plateau and the known velocity structure of the Pilbara Craton indicates that the basin is the product of a major episode of lower crustal thinning that lasted from the Carboniferous to the Jurassic. During this thinning phase, almost the entire crust below a mid-crustal discontinuity was removed. Commensurate upper crustal thinning probably took place on the conjugate margin which was removed at breakup.
A new drought index that considers the joint effects of climate and land surface change

This study proposes a hydrological drought index, the standardized wetness index (SWI), by combining the structure of the Standardized Precipitation‐Evapotranspiration Index and actual‐evaporation‐based residual water‐energy ratio, in which actual evaporation is estimated using the Budyko hypothesis. The SWI requires three parameters—precipitation, potential evaporation, and parameter n of a Budyko‐type formula. Based on different types of n (fixed or dynamic), SWI can be used to estimate the dryness/wetness resulting from climate change (variability) solely, and from the joint effects of climate and land surface change (variability). Performance of SWI is evaluated using historical droughts and by comparing to the self‐calibrated Palmer Drought Severity Index. Results show that SWI effectively captures global droughts. Furthermore, a case study in two catchments with significant land surface modification indicates that the joint effects of climate and land surface have greater impacts on dryness/wetness in the water‐limited Wuding catchment than in the energy‐limited Poyang catchment.
Telomere length and telomerase activity during folliculogenesis in mammals

Telomeres are repetitive non-coding DNA sequences located at the ends of chromosomes in eukaryotic cells. Their most important function is to protect chromosome ends from being recognized as DNA damage. They are also implicated in meiosis and synapse formation. The length of telomeres inevitably shortens at the end of each round of DNA replication and, also, as a consequence of the exposure to oxidative stress and/or genotoxic agents. The enzyme telomerase contributes to telomere lengthening. It has been reported that telomerase is exclusively expressed in germ cells, granulosa cells, early embryos, stem cells, and various types of cancerous cells. Granulosa cells undergo many mitotic divisions and either granulosa cells or oocytes are exposed to a variety of genotoxic agents throughout folliculogenesis; thus, telomerase plays an important role in the maintenance of telomere length. In this review article, we have comprehensively evaluated the studies focusing on the regulation of telomerase expression and activity, as well as telomere length, during folliculogenesis from primordial to antral follicles, in several mammalian species including mice, bovines, and humans. Also, the possible relationships between female infertility caused by follicular development defects and alterations in the telomeres and/or telomerase activity are discussed.

Two types of ultrasonic sensors are presented for in situ capability development of ice detection and structure thickness measurement. These piezoelectric ﬁlm based sensors have been fabricated by a sol–gel spray technique for aircraft environments and for temperatures ranging from − 80 to 100 ◦ C. In one sensor type, piezoelectric ﬁlms of thickness greater than 40 μ m are deposited directly onto the interior of a 1.3 mm thick aluminum (Al) alloy control surface (stabilizer) of an aircraft wing structure as integrated ultrasonic transducers (UTs). In the other sensor type, piezoelectric ﬁlms are coated onto a 50 μ m thick polyimide membrane as ﬂexible UTs. These were subsequently glued onto similar locations at the same control surfaces. In situ monitoring of stabilizer outer skin thickness was performed. Ice build-up ranging from a fraction of 1 mm to less than 1.5 mm was also detected on a 3 mm thick Al plate. Measurements using these ultrasonic sensors agreed well with those obtained by a micrometer. Tradeoffs of these two approaches are presented.
Shape and intrusion history of the Late Caledonian Newry Igneous Complex, Northern Ireland

The Tellus high-resolution airborne magnetic and radiometric maps define previously unmapped zones within the Newry Igneous Complex, County Down. High-precision uranium–lead zircon dating of nine rock samples from different parts of the complex provides a robust set of age constraints (c.414–407 Ma), which confirm that the different plutons of the complex young towards the south-west. Combined, these new data allow an innovative model of intrusion to be developed, with intrusion beginning in the north-east and progressing towards the south-west.
Livelihoods and Land Uses Produced Together: Evidence from Rural Malawi

Land use and livelihood studies rarely engage dialectical thinking to explain how change occurs in rural, peasant economies. In this paper, I employ the dialectical concepts of contradiction and sublation to investigate the ways in which livelihoods and land uses are produced together at the household scale. Using quantitative and qualitative surveys, I demonstrate the degree to which land use and livelihoods are internally related and produced together as a result of households overcoming contradictions facing them in their everyday lives. I conclude by relating these findings back to relevant theoretical concepts.
Learning Programming Using Educational Robotics

Research reported in this paper fits into the generic problem of programming learning. In this context, the primary research objective of this study is to analyze if robotics facilitates programming learning. To tackle the problem, we developed a robotic kit and a small course. The robotic kit used Arduino platform and was presented in the context of this course. The course consisted of programming concepts. This course was taught to higher education students, with no previous programming knowledge. In the end, we analyzed the impact of the course. Results demonstrate that students showed interest in using robotics to learn computer programming. Results also showed the main adoption determinants of the robotic kit. Enjoyment is the most relevant to the robotic kit intention to use. However, perceived ease is the dimension that has more impact on robotic kit usage.

Mantle plumes are thought to play a key role in transferring heat from the core–mantle boundary to the lithosphere, where it can signiﬁcantly inﬂuence plate tectonics. On impinging on the lithosphere at spreading ridges or in intra-plate settings, mantle plumes may generate hotspots, large igneous provinces and hence considerable dynamic topography. However, the active role of mantle plumes on subducting slabs remains poorly understood. Here we show that the stagnation at 660 km and fastest trench retreat of the Tonga slab in Southwestern Paciﬁc are consistent with an interaction with the Samoan plume and the Hikurangi plateau. Our ﬁndings are based on comparisons between 3D anisotropic tomography images and 3D petrological-thermo-mechanical models, which self-consistently explain several unique features of the Fiji–Tonga region. We identify four possible slip systems of bridgmanite in the lower mantle that reconcile the observed seismic anisotropy beneath the Tonga slab ( V SH 4 V SV ) with thermo-mechanical calculations.
Nitrate content and potential microbial signature of rock glacier outflow, Colorado Front Range

Here we characterize the nutrient content in the outflow of the Green Lake 5 rock glacier, located in the Green Lakes Valley of the Colorado Front Range. Dissolved organic carbon (DOC) was present in all samples with a mean concentration of 0·85 mg L−1 . A one‐way analysis of variance test shows no statistical difference in DOC amounts among surface waters (p = 0·42). Average nitrate concentrations were 69 µmoles L−1 in the outflow of the rock glacier, compared to 7 µmoles L−1 in snow and 25 µmoles L−1 in rain. Nitrate concentrations from the rock glacier generally increased with time, with maximum concentrations of 135 µmoles L−1 in October, among the highest nitrate concentrations reported for high‐elevation surface waters. These high nitrate concentrations appear to be characteristic of rock glacier outflow in the Rocky Mountains, as a paired‐difference t‐test shows that nitrate concentrations from the outflow of 7 additional rock glaciers were significantly greater compared to their reference streams (p = 0·003). End‐member mixing analysis suggest that snow was the dominant source of nitrate in June, ‘soil’ solution was the dominant nitrate source in July, and base flow was the dominant source in September. Fluoresence index values and PARAFAC analyses of dissolved organic matter (DOM) are also consistent with a switch from terrestrial DOM in the summer time period to an increasing aquatic‐like microbial source during the autumn months.

Carbon stock and plants biodiversity of pekarangan in Cisadane watershed West Java

The presence of vegetation in Pekarangan can be proposed to mitigate global climate change impacts by CO2 sequestration and at the same time to promote the availability of food for the community. The aims of this research is to calculate carbon stock and biodiversity in pekarangan, and to compare carbon stock and biodiversity on three levels of Cisadane Watershed. Four groups of Pekarangan defined on a purposive random sampling. Allometric models were developed to estimate aboveground biomass of vegetation, and an inventory was conducted in 48 pekarangan. Shannon Weiner Index (H’) and Margalef Index (Dm) are used to evaluate biodiversity, averaged 2,84 and 5,10 (G1); 2,55 and 4,27 (G2); 2,56 and 4,52 (G3); 2,68 and 4,84 (G4), while carbon stock averaged 33,20 Mg Carbon/ha (G1); 29,97 Mg/ha (G2); 59,18 Mg/ha (G3); and 40,98 Mg/ha (G4). There is no relationship between biodiversity with carbon stock on pekarangan (R2 = 0,02), or tree’s biodiversity with carbon stock (R2 = 0,23). High resolution satellite imagery can be used to extrapolate carbon stock and plants biodiversity of Pekarangan at watershed level.
Turning Visitors into Customers: A Usability-Centric Perspective on Purchase Behavior in Electronic Channels

We develop a theoretical model for predicting purchase behavior in electronic channels. The model suggests that website use (i.e., technology use), a key indicator of the degree to which a site is sticky, is a significant antecedent of purchase behavior. Furthermore, we relate the usability of a website to use behavior and purchase behavior. Specifically, individual characteristics and product type are argued to differentially influence the weights that customers place on five different categories of usability. The weighted ratings of the five categories together determine use behavior and purchase behavior, after controlling for purchase need, experience with similar sites, and previous purchase on the specific sites. The model was tested in a longitudinal field study among 757 customers who provided usability assessments for multiple websites from four different industriesi.e. , airlines, online bookstores, automobile manufacturers, and car rental agencies. Six months later, 370 of these individuals provided responses to help understand the transition from visitor to customer, i.e., whether they actually transacted with a specific website. Results provided strong support for the model and yield important theoretical and practical implications.
Estimating Teacher Impacts on Student Achievement: An Experimental Evaluation

We used a random-assignment experiment in Los Angeles Unified School District to evaluate various non-experimental methods for estimating teacher effects on student test scores. Having estimated teacher effects during a pre-experimental period, we used these estimates to predict student achievement following random assignment of teachers to classrooms. While all of the teacher effect estimates we considered were significant predictors of student achievement under random assignment, those that controlled for prior student test scores yielded unbiased predictions and those that further controlled for mean classroom characteristics yielded the best prediction accuracy. In both the experimental and non-experimental data, we found that teacher effects faded out by roughly 50 percent per year in the two years following teacher assignment.
Whole genome association studies in complex diseases: where do we stand?

Hundreds of genome-wide association studies have been performed in recent years in order to try to identify common variants that associate with complex disease. These have met with varying success. Some of the strongest effects of common variants have been found in lateonset diseases and in drug response. The major histocompatibility complex has also shown very strong association with a variety of disorders. Although there have been some notable success stories in neuropsychiatric genetics, on the whole, common variation has explained little of the high heritability of these traits. In contrast, early studies of rare copy number variants have led rapidly to a number of genes and loci that strongly associate with neuropsychiatric disorders. It is likely that the use of whole-genome sequencing to extend the study of rare variation in neuropsychiatry will greatly advance our understanding of neuropsychiatric genetics.
Generalized Biwords for Bitext Compression and Translation Spotting

Large bilingual parallel texts (also known as bitexts) are usually stored in a compressed form, and previous work has shown that they can be more efficiently compressed if the fact that the two texts are mutual translations is exploited. For example, a bitext can be seen as a sequence of biwords --pairs of parallel words with a high probability of cooccurrence-- that can be used as an intermediate representation in the compression process. However, the simple biword approach described in the literature can only exploit one-to-one word alignments and cannot tackle the reordering of words. We therefore introduce a generalization of biwords which can describe multi-word expressions and reorderings. We also describe some methods for the binary compression of generalized biword sequences, and compare their performance when different schemes are applied to the extraction of the biword sequence. In addition, we show that this generalization of biwords allows for the implementation of an efficient algorithm to look on the compressed bitext for words or text segments in one of the texts and retrieve their counterpart translations in the other text --an application usually referred to as translation spotting-- with only some minor modifications in the compression algorithm.

Formation of shatter cones in MEMIN impact experiments

Shatter cones are the only macroscopic feature considered as evidence for shock metamorphism. Their presence is diagnostic for the discovery and verification of impact structures. The occurrence of shatter cones is heterogeneous throughout the crater record and their geometry can diverge from the typical cone shape. The precise formation mechanism of shatter cones is still not resolved. In this study, we aim at better constraining the boundary conditions of shatter cone formation in impact experiments and test a novel approach to qualitatively and quantitatively describe shatter cone geometries by white light interferometry. We recovered several ejected fragments from MEMIN cratering experiments that show slightly curved, striated surfaces and conical geometries with apices of 36°–52°. These fragments fulfilling the morphological criteria of shatter cones were found in experiments with 20–80 cm sized target cubes of sandstone, quartzite and limestone, but not in highly porous tuff. Targets were impacted by aluminum, steel, and iron meteorite projectiles at velocities of 4.6–7.8 km s−1. The projectile sizes ranged from 2.5–12 mm in diameter and produced experimental peak pressures of up to 86 GPa. In experiments with lower impact velocities shatter cones could not be found. A thorough morphometric analysis of the experimentally generated shatter cones was made with 3D white light interferometry scans at micrometer accuracy. SEM analysis of the surfaces of recovered fragments showed vesicular melt films alternating with smoothly polished surfaces. We hypothesize that the vesicular melt films predominantly form at strain releasing steps and suggest that shatter cones are probably mixed mode fractures.
Helminths of Apodemus sylvaticus (Muridae) distributed on the southern european border (Italian peninsula)

Cinq aires du sud de l'Italie ont ete examinees et ont revele la presence d'Apodemus sylvaticus. Au total, 14 especes d'Helminthes intestinaux ont ete identifiees : Trematoda (Corrigia vitta), Cestoda (larves de Taenia taeniaeformis, Gallegoides arfaai, Hymenolepis sp. et Rodentolepis straminea), et Nematoda (Trichuris muris, Aonchotheca muris-sylvatici, A. sp., Mastophorus muris, Rictularia proni, Heligmosomoides polygyrus, Syphacia stroma, S. frederici et Aspiculuris tetraptera). L'intensite d'infection par les Helminthes intestinaux est plus importante chez les adultes et chez les mâles. Le nombre d'especes rencontrees en Calabre s'est revele moins important que celui de la communaute de Vers identifies en Europe du Nord et dans les aires continentales. La richesse specifique, en effet, semble etre identique a celle observee pour les vertebres: dans une peninsule, le nombre d'especes diminue parce que l'environnement reduit progressivement sa capacite a etre colonise par des vertebres.
Devonian tectonothermal activity in the Sowie Góry gneissic block, Sudetes, southwestern Poland: evidence from Rb-Sr and U-Pb isotopic studies

Dewonska aktywnośc tektonometamorficzna w gnejsach bloku Gor Sowich w świetle badan izotopowych Rb-Sr i U-Pb In widely developed biotite-oligoclase-quartz paragneiss a U-Pb upper intercept age of 1750 ±270 is interpreted as a (possibly mixed) sedimentary provenance age. U-Pb monazite and Rb-Sr biotite ages of 381 ± 2 Ma and ca. 370-360 Ma, respectively, indicate rapid Devonian cooling from upper amphibolite to greenschist facies temperatures. The isotopic data are consistent with stratigraphic evidence for rapid Devonian uplift. U-Pb zircon isotopic data support, but do not prove conclusively, that the metamorphism associated with D2 in the Sowie Gory block was Devonian in age. The Z)4 event has been dated at 370 ± 4 Ma using Rb-Sr in large muscovite books from a pegmatite in an F4 hinge zone. Low-mid-amphibolite facies Ds activity cannot be much younger in view of the biotite cooling ages. The D2-5 tectonothermal activity, rapid cooling and uplift in the Sowie Gory block of the Middle Sudetes pre-date the early Carboniferous granulite facies metamorphism and granitic plutonism further S in the Moldanubian zone of the Hercynides in Czechoslovakia.

Strong biotic influences on regional patterns of climate regulation services

Climate regulation services from forests are an important leverage in global‐change mitigation treaties. Like most ecosystem services, climate regulation is the product of various ecological phenomena with unique spatial features. Elucidating which abiotic and biotic factors relate to spatial patterns of climate regulation services advances our understanding of what underlies climate‐mitigation potential and its variation within and across ecosystems. Here we quantify and contrast the statistical relations between climate regulation services (albedo and evapotranspiration, primary productivity, and soil carbon) and abiotic and biotic factors. We focus on 16,955 forest plots in a regional extent across the eastern United States. We find the statistical effects of forest litter and understory carbon on climate regulation services to be as strong as those of temperature‐precipitation interactions. These biotic factors likely influence climate regulation through changes in vegetation and canopy density, radiance scattering, and decomposition rates. We also find a moderate relation between leaf nitrogen traits and primary productivity at this regional scale. The statistical relation between climate regulation and temperature‐precipitation ranges, seasonality, and climatic thresholds highlights a strong feedback with global climate change. Our assessment suggests the expression of strong biotic influences on climate regulation services at a regional, temperate extent. Biotic homogenization and management practices manipulating forest structure and succession will likely strongly impact climate‐mitigation potential. The identity, strength, and direction of primary influences differed for each process involved in climate regulation. Hence, different abiotic and biotic factors are needed to monitor and quantify the full climate‐mitigation potential of temperate forest ecosystems.
