Parasibirskite, a new mineral from Fuka, Okayama Prefecture, Japan

Abstract Parasibirskite, with the ideal formula Ca2B2O5 · H2O, is a new mineral species found at Fuka, Okayama Prefecture, Japan. It is a polymorph of sibirskite, CaHBO3, and occurs as subparallel aggregates of tabular crystals up to 40 × 20 × 3 μm in size. Associated minerals are takedaite, olshanskyite, sibirskite, frolovite and calcite. The mineral is white, and has a weak pearly luster. Optically, the mineral is biaxial positive, α 1.556(2), β 1.593(2), γ 1.663(2) (λ 589 nm). The Vickers microhardness of aggregates is 121 kg mm-2. The mineral is monoclinic with space group of P21/m a 6.722(4), b 5.437(2), c 3.555(2) Å, β 93.00(5)°, V 129.8(2) Å3. The strongest lines in the X-ray powder pattern [d in Å (I)(hkl)] are 2.237(100)(300), 6.73(70)(100), 2.975(60)(011), 3.354(30)(200), 2.855(20)(210) and 1.776(20) (002). Wet chemical analysis, electron-microprobe analysis and ICP emission spectrometry give the values CaO 56.06 %, B2O3 34.10 %, H2O 9.97 % and total 100.13%. The empirical formula calculated on the basis of O = 6 is Ca1.985B1. 945O4.901 · 1.099H2O, for Z = 1, Dcalc 2.54 and Dmeas 2.50(1) g cm-3. Parasibirskite is formed by hydrothermal alteration of takedaite.
Survival and Abundance Of Three Species Of Mice In Relation to Density Of Shrubs and Prescribed Fire In Understory Of An Oak Woodland In California

Abstract We investigated effects of prescribed understory fire and shrub density on the pinyon deermouse (Peromyscus truei), brush deermouse (P. boylii), and California pocket mouse (Chaetodipus californicus) in a mixed blue oak-coast live oak (Quercus douglasii-Q. agrifolia) woodland of coastal-central California. We simultaneously estimated survival and abundance of all species during pre-burn and post-burn. Abundance of pinyon deermice and California pocket mice was significantly higher in plots with high (>25%) shrub cover compared to plots with low (<10%) shrub cover. A light-to-moderate intensity, prescribed, understory fire had no significant effect on survival for any of the three species we investigated. The fire significantly reduced abundance of pinyon deermice in the trapping session immediately after the fire, but abundance increased in subsequent trapping sessions relative to controls. Low intensity, prescribed, understory fire in oak woodland is unlikely to significantly alter populations of rodents if patches of well-structured habitat are maintained. Benefits of prescribed fire for oak woodlands in reduction of the risk of wildfire and rejuvenation of vegetation likely outweigh any short-term negative effects on populations of mice.
Longitudinal variations of electron temperature and total ion density in the sunset equatorial topside ionosphere

Based on the DMSP F13 Satellite observations from 1995 to 2005, the longitudinal distributions of the electron temperature (Te) and total ion density (Ni) in the sunset equatorial topside ionosphere are examined. The results suggest that the longitudinal variations of both Te and Ni exhibit obvious seasonal dependence as follows: (1) wavenumber‐four longitudinal structure in equinox, (2) three peaks structure in June solstice, and (3) two peaks structure in December solstice. Moreover, the longitudinal variations of Te and Ni show significant anti‐correlation, and we speculate that the longitudinal variation of Te may result from that of Ni which can control Te through the electron cooling rate. The wavenumber‐four longitudinal structures of both Te and Ni in equinox may relate to the eastward propagating zonal wavenumber‐3 diurnal tide (DE3), which has effect on the amplitude of the daytime zonal electric field. The longitudinal variation of Te and Ni in the two solstices may be caused both by longitudinal variation of geomagnetic declination and DE3.
Analysis of Different Gray Zone Treatments in WRF-LES Real Case Simulations

Abstract. When conducting meso-micro scale coupled atmospheric simulations, it is crucial to ensure an adequate treatment of gray zone or terra incognita resolutions in which a large portion of the kinetic energy is naturally produced by the momentum balance equations in the model, while the remaining part still needs to be parameterized. In this work, we conduct three multi-day, real case, full-physics atmospheric simulations that are fully coupled from the meso to the micro scale and in which the only difference is the treatment of boundary layer physics at the gray zone domain. One simulation uses a well-established parameterization, another uses its scale-aware version previously modified to accommodate gray zone resolutions, and a final one uses no parameterization at all and assumes that the gray zone domain can be run in large-eddy simulation (LES) mode. The simulated fields are cross-compared, and further compared to measurements collected during the Prince Edward Island Wind Energy Experiment. Use of LES in the gray zone domain influences the flow fields in a manner that is robust to temporal averaging. The best predictions of vertical wind shear were found for the simulations in which the gray zone is parameterized, and the inclusion of a micro scale nest run in LES mode within the gray zone domains increased the model errors by producing overly homogeneous flow fields. The parameterized simulations also produced better agreement in terms of kinetic energy spectra at the two innermost simulation domains. In the gray zone domain, the energy decays as f−3 throughout most of the spectral range considered. In the micro scale domain, the same is only seen in the low-frequency end of the gray zone spectral range. In the high-frequency end, the energy decay follows a f−1 slope. Outside the gray zone spectral range, the micro scale simulated spectra follow the expected f−5/3 slope and produce good agreement with measurements.
Retrieval of exoplanet emission spectra with HyDRA

Thermal emission spectra of exoplanets provide constraints on the chemical compositions, pressure-temperature (P-T) profiles, and energy transport in exoplanetary atmospheres. Accurate inferences of these properties rely on the robustness of the atmospheric retrieval methods employed. While extant retrieval codes have provided significant constraints on molecular abundances and temperature profiles in several exoplanetary atmospheres, the constraints on their deviations from thermal and chemical equilibria have yet to be fully explored. Our present work is a step in this direction. We report HyDRA, a disequilibrium retrieval framework for thermal emission spectra of exoplanetary atmospheres. The retrieval code uses the standard architecture of a parametric atmospheric model coupled with Bayesian statistical inference using the Nested Sampling algorithm. For a given dataset, the retrieved compositions and P-T profiles are used in tandem with the GENESIS self-consistent atmospheric model to constrain layer-by-layer deviations from chemical and radiative-convective equilibrium in the observable atmosphere. We demonstrate HyDRA on the Hot Jupiter WASP-43b with a high-precision emission spectrum. We retrieve an H2O mixing ratio of log(H2O) = -3.54^{+0.82}_{-0.52}, consistent with previous studies. We detect H2O and a combined CO/CO2 at 8-sigma significance. We find the dayside P-T profile to be consistent with radiative-convective equilibrium within the 1-sigma limits and with low day-night redistribution, consistent with previous studies. The derived compositions are also consistent with thermochemical equilibrium for the corresponding distribution of P-T profiles. In the era of high precision and high resolution emission spectroscopy, HyDRA provides a path to retrieve disequilibrium phenomena in exoplanetary atmospheres.
The Impact of Status Consumption on Shopping Styles: An Exploratory Look at the Millennial Generation

This study examined millennial consumers’ relationships between status consumption and Sproles and Kendall’s (1986) Consumer Styles Inventory (CSI). It was found that status consumption was a positive antecedent to five of the eight CSI’s shopping style characteristics: brand conscious, novelty and fashion conscious, recreational and shopping conscious, impulsive/careless, and habitual/brand loyal, but not to the characteristics of perfectionist, confused by overchoice, and price conscious. The results suggest that those millennial consumers who are motivated to consume for status will utilize the shopping styles of being brand conscious, novelty/fashion conscious, recreational shoppers, impulsive shoppers, and brand loyal.
Memory, attention and interaction in early development : exploring individual differences among typical children and children with autism

Strid, Karin (2007). Memory, attention and interaction in early development: Exploring individual differences among typical children and children with autism. Department of Psychology, Goteborg University, Sweden. This thesis aimed to study differences in early memory ability, social attention and interaction and how these different areas affect language and cognitive development. This was done using a longitudinal approach where a group of children were followed from infancy to childhood and also in a comparative study where a group of children diagnosed with autism spectrum disorder was compared to a group of typically developing children, matched on language age. Study I investigated typically developing infants and showed that recall memory (measured with deferred imitation), visual recognition memory and social communicative ability could explain a large part of the differences in early language acquisition, and also that recall memory made the strongest contribution to this explanation. Study II was a follow-up of the same children as in study I, and showed that a combined low performance on tests of both recall memory and social communication in infancy was related to poorer cognitive outcome beyond infancy, when the children had reached 4 years of age. In study III, deferred imitation and different aspects of social communication were investigated in children with autism and in comparison with typically developing children. The results revealed that children with autism and low language level showed reduced performance in all areas of social communication as well as on deferred imitation. Children with autism and a higher language level, however, performed on a similar level as the typically developing children on all but one measure of social communication, but they still showed reduced performance on deferred imitation. Study IV included the same children as study III, and their performance on pretend play as well as child-parents interaction during play was investigated in relation to language level, joint attention and deferred imitation. Pretend play was related to the child’s language level, joint attention and deferred imitation. The way parents interacted verbally with their child differed between parents of children with autism compared to parents of typically developing children, but also on the child’s language level. The present thesis suggests that it is beneficial to investigate social and cognitive areas in combination if the aim is to understand how early abilities affect later development. The results contribute to the understanding of language development in autism and also point to the importance of considering the child’s developmental level. Children with autism showed large individual differences in many different areas, and the results suggest that this was partly due to the child’s language level.
Use of Blackboard Learning Management System: An Empirical Study of Staff Behavior at a South African University

This study explores the use of a Learning management system (LMS), Blackboard, among academics at a South African university of technology. Based on the literature and the Unified Theory of Acceptance and Use of Technology (UTAUT) model, four constructs which influence academics’ usage and behavioural intention to adopt LMS were considered: performance expectancy, effort expectancy, facilitating conditions, and social influence. Data was collected from 100 academics through a survey questionnaire, and correlations and regression was used to analyse the relationships. The results indicate that, facilitating conditions is the most influential factor explaining the usage of, and intention to use LMS among both users and non-users, while the set of variables, performance expectancy, effort expectancy, social influence, and facilitating conditions were not able to predict a significant amount of variance in intention to use LMS. Implications for practice are presented.
Saline lake turbidites in the La Coipa area, Northern Chile

ABSTRACT. An unusual and very distinctive occurrence of evaporitic gypsum in association with clastic turbidites was deposited in a still, anoxic lake environment in the La Coipa area of Northern Chile. The sequence of exceptionally fine-grained, red-coloured mudstones and graded sandstones is characterised by abundant small gypsum nodules and veins. The nodules probably resulted from the recrystallization of gypsum-anhydrite transported by turbidity currents and slumps from the shallow lake margins into deeper water. Following the formation of the superficial slumps the strata were subjected to compressive thrusting. This, in turn, was followed by vertical extension and a second episode of NNE-directed thrusting. The gypsum-filled veins, produced during the vertical extension, possibly originated as a result of the dissolution of underlying evaporites. The strata, apparently, form the oldest part of the Lower Triassic La Coipa Beds, which are themselves part of a widespread succession of Triassic marine and continental rift-related sediments in Northern Chile. RESUMEN. Turbiditas de lago salino en el area de La Coipa, norte de Chile. Una inusual y muy distintiva ocurrencia de yeso evaporitico asociado a turbiditas elasticas se deposito en un tranquilo ambiente lacustre anoxico en el area de La Coipa en el norte de Chile. La secuencia de fangolitas rojas, de grano excepcionalmente fino y de areniscas gradadas se caracteriza por abundantes y pequenos nodulos y venas de yeso. Los nodulos, probablemente, fueron el resultado de la recristalizacion de anhidrita-yeso transportados por corrientes de turbidez y derrumbes desde los margenes lacustres someros a aguas mas profundas. Despues de los derrumbes superficiales, los estratos fueron sometidos a un corrimiento compresivo. Esto, a su vez, fue seguido por una extension vertical y un segundo episodio de corrimiento con direccion nor-noreste. Las venas de yeso, consecuencia de la extension vertical, posiblemente se originaron como resultado de la disolucion de evaporitas subyacentes. Aparentemente, los estratos constituyen la parte mas antigua de los Estratos de la Coipa del Triasico Inferior, los cuales forman parte de una sucesion de sedimentos marinos y continentales de 'rift' del Triasico, ampliamente distribuidos en el norte de Chile.
Radiation-induced chromosomal aberrations in grape Phylloxera

Chromosomal aberrations in phylloxera females induced by different doses of gamma irradiation were detected. The results showed that the chromosomes of all tested embryos of irradiated phylloxera had aberrations, regardless of dose. When phylloxera nymphs were irradiated, the chromosomal number on the metaphase plate of some embryos’ cells was increased. The result indicated that the chromosomal aberrations influenced the mortality, longevity and reproduction of phylloxera. Eight autosomal chromosomes were identified according to their length. Additionally, the karyotype of irradiated and unirradiated populations of local phylloxera strain was defined.
The expression of microRNA-155 and 127 in the neonatal SD rats with acute lung injury induced by lipopolysaccharide

Aim: This study was to observe the changes of the gene expression of microRNA-155 and 127 in the neonatal rats with Acute Lung Injury (ALI). Methods: Eighty neonatal SD rats were randomly divided into experimental groups (intraperitoneal injection with LPS, n=60) and control (intraperitoneal injection with NS, n=20). Neonatal rats in experimental groups (LPS 1 mg, 2 mg and 3 mg group, n=20) were received corresponding dose of LPS (1, 2 and 3 mg/kg, diluted with saline to 0.2 ml), while neonatal rats in control group were injected 0.2 ml saline respectively. Then we killed rats at 1 h, 6 h, 12 h and 24 h respectively in each group. The lung general pathological changes were observed. The expression of microRNA-155 and 127 were detected by semi-quantitative reverse transcription-polymerase chain reaction. Tumor Necrosis Factor-α (TNF-α) and Interleukelin-6 (IL-6) in Bronchoalveolar Lavage Fluid (BALF) were detected by enzyme-linked immunosorbent assay. The expression of TNF-α and IL-6 protein in lung tissue were detected by western blotting. Results: The expression of microRNA-155 was up-regulated in the tissues and BALF in a dose and timedependent manner and microRNA-127 down-regulated. The difference were statistically significant when compared with the control group (all P<0.05). The TNF-α and IL-6 level of BALF rats with ALI in LPS groups were increased compared with the control group in a dose-dependent manner (all P<0.05). A similar trend had been seen in TNF-α and IL-6 protein level of lung tissues, the difference was statistically significant. Conclusion: The expression of microRNA-155 and 127 are associated with severity of the ALI in a dose and time-dependent manner, and they might be considered as potential biomarkers for early diagnosis of ALI.
A Novel Selective Ensemble Algorithm for Imbalanced Data Classification Based on Exploratory Undersampling

Learning with imbalanced data is one of the emergent challenging tasks in machine learning. Recently, ensemble learning has arisen as an effective solution to class imbalance problems. The combination of bagging and boosting with data preprocessing resampling, namely, the simplest and accurate exploratory undersampling, has become the most popular method for imbalanced data classification. In this paper, we propose a novel selective ensemble construction method based on exploratory undersampling, RotEasy, with the advantage of improving storage requirement and computational efficiency by ensemble pruning technology. Our methodology aims to enhance the diversity between individual classifiers through feature extraction and diversity regularized ensemble pruning. We made a comprehensive comparison between our method and some state-of-the-art imbalanced learning methods. Experimental results on 20 real-world imbalanced data sets show that RotEasy possesses a significant increase in performance, contrasted by a nonparametric statistical test and various evaluation criteria.
Periodicity, Stability, and Boundedness of Solutions to Certain Second Order Delay Differential Equations

The behaviour of solutions to certain second order nonlinear delay differential equations with variable deviating arguments is discussed. The main procedure lies in the properties of a complete Lyapunov functional which is used to obtain suitable criteria to guarantee existence of unique solutions that are periodic, uniformly asymptotically stable, and uniformly ultimately bounded. Obtained results are new and also complement related ones that have appeared in the literature. Moreover, examples are given to illustrate the feasibility and correctness of the main results.
The effect of a probiotic composed of Lactobacillus and yeats, and of flavomycin on the performance and faecal microflora of broiler chickens

The experiment was carried out on 99 female broilers, allocated to 3 groups of 33 birds, kept in individual cages. A wheatand soyabean meal-based diet was formulated and divided into 3 batches: C (unsupplemented), A (supplemented with flavomycin), and P (supplemented with a probiotic composed of lactic acid bacteria, yeasts, and yucca extract). Diets were fed from day 1 to 41 of life. Final BW was on average 2.4 kg in all groups, FCR was 1.63 kg feed/kg BWG, neither BWG nor FCR nor mass of the liver, pancreas and gastrointestinal tract were significantly influenced by supplementing the diet with either additive. GI tract digesta pH was lower in groups P and A than in the control group, significantly (P<0.05) lower in the crop and ileal content, only. In group P the Lactobacilli and E. coli counts in excreta were higher (P<0.05) in 1to 3-week old chickens than in group C, while the Clostridium count, lower (P<0.05) than in group A. In the following weeks the tendency was similar, but insignificant. It may be concluded that the studied probiotic can be considered to be a substitute for antibiotic growth promoters in broiler diets.
Occurrence of Ceratitis capitata and Anastrepha fraterculus (Diptera: Tephritidae) on Cultivated, Exotic Fruit Species in the Highland Valleys of Tucuman in Northwest Argentina

ABSTRACT Fruits from 6 exotic, cultivated fruit species were collected in the Tafí and Calchaquí valleys between Jan 2000 and Jan 2002 to determine the occurrence of Ceratitis capitata (Wiedemann) and Anastrepha fraterculus (Wiedemann) and the corresponding fruit infestation levels. The valleys are situated in the western semiarid highlands of Tucumán province (NW Argentina) and the altitude ranges from 1,800 to 2,014 m above sea level. The fruit species surveyed were Cydonia oblonga Miller, Malus domestica Borkh. , Prunus armeniaca L. , P. domestica L. , P. persica (L.) Batsch, and Pyrus communis L. (Rosaceae). Out of a total of 2,129 puparia recovered from infested fruit, 2,112 (98.8%) were C. capitata and only 27 (1.2%) A. fraterculus. Ceratitis capitata was recovered from all fruit species and it was the dominant species. Anastrepha fraterculus was only recovered from C. oblonga, P. persica and P. domestica. All Prunus species and P. communis were the host plants that were infested most by C. capitata. The infestation data of C. oblonga, P. communis and M. domestica demonstrated that these 3 fruit species were acceptable host plants for C. capitata in Tucumán. This study provides the first record of both C. capitata and A. fraterculus infesting fruit species in semiarid highland valleys in Tucumán, and it also expands the altitudinal range of distribution of these two tephritid species to 2,014 m within the Tucumán province.
