Regional Eta model experiments: SALLJEX and MCS development

[1] The rainfall regime over La Plata Basin is strongly influenced by Mesoscale Convective Systems (MCS) that develop during night time, associated with the Low-Level Jet (LLJ) to the east of the Andes. Since they are mesoscale systems, their predictability depends on the model resolution and its ability to represent the main features associated with their development. This study aimed at finding the best configuration of the regional Eta model applied to the region of frequent MCS development to the east of the Andes and to analyze the performance of the model at high resolution, simulating specific MCS cases using two convection schemes. Three experiments were performed for the South American Low-Level Jet Experiment (SALLJEX) period. Performance of the nonhydrostatic version was better than the hydrostatic version in cases of MCS development. The use of estimated instead of climatological soil moisture in the model, improved the results for several synoptic variables. Evaluation of the convection parameterization scheme indicated a better simulation using the Kain-Fritsch (KF) rather than the Betts-Miller-Janjic scheme in the cases of MCS development. Therefore the best configuration of the Eta model for the simulation of the MCS occurrences over northern Argentina is the nonhydrostatic version using KF convection scheme and estimated soil moisture. With this configuration, the model was able to simulate the precipitation and the main atmospheric characteristics associated with MCS development, such as the upper level jet, the LLJ, humidity, and associated mechanisms for ascending motion, 72 hours in advance.
Land movement monitoring at the Mavropigi lignite mine using spaceborne D-InSAR

This paper examines the capability of remote sensing radar interferometry to monitor land movements, as it varies with time, in areas close to open pit lignite mines. The study area is the “Mavropigi” lignite mine in Ptolemais, Northern Greece; whose continuous operation is of vital importance to the electric power supply of Greece. The mine is presently 100-120m deep while horizontal and vertical movements have been measured in the vicinity of the pit. Within the mine, ground geodetic monitoring has revealed an average rate of movement amounting to 10-20mm/day at the southeast slopes. In this work, differential interferometry (DInSAR), using 19 Synthetic Aperture Radar (SAR) images of ALOS satellite, has been applied to monitor progression of land movement caused my mining within the greater area of “Mavropigi” region. The results of this work show that DInSAR can be used effectively to capture ground movement information, well before signs of movements can be observed visually in the form of imminent fissures and tension cracks. The advantage of remote sensing interferometry is that it can be applied even in inaccessible areas where monitoring with ground equipment is either impossible or of high-cost (large areas).
Elsevier Editorial System(tm) for Journal of Web Semantics Manuscript Draft Title: the Two Cultures: Mashing up Web 2.0 and the Semantic Web

A common perception is that there are two competing visions for the future evolution of the Web: the Semantic Web and Web 2.0. A closer look, though, reveals that the core technologies and concerns of these two approaches are complementary and that each field can and must draw from the other's strengths. We believe that future Web applications will retain the Web 2.0 focus on community and usability, while drawing on Semantic Web infrastructure to facilitate mashup-like information sharing. However, there are several open issues that must be addressed before such applications can become commonplace. In this paper, we outline a semantic weblogs scenario that illustrates the potential for combining Web 2.0 and Semantic Web technologies, while highlighting the unresolved issues that impede its realization. Nevertheless, we believe that the scenario can be realized in the short-term. We point to recent progress made in resolving each of the issues as well as future research directions for each of the communities.

Engineering Optogenetic Control of Endogenous p53 Protein Levels

The transcription factor p53 is a stress sensor that turns specific sets of genes on to allow the cell to respond to the stress depending on its severity and type. p53 is classified as tumor suppressor because its function is to maintain genome integrity promoting cell cycle arrest, apoptosis, or senescence to avoid proliferation of cells with damaged DNA. While in many human cancers the p53 gene is itself mutated, there are some in which the dysfunction of the p53 pathway is caused by the overexpression of negative regulators of p53, such as Mdm2, that keep it at low levels at all times. Here we develop an optogenetic approach to control endogenous p53 levels with blue light. Specifically, we control the nuclear localization of the Mmd2-binding PMI peptide using the light-inducible export system LEXY. In the dark, the PMI-LEXY fusion is nuclear and binds to Mdm2, consenting to p53 to accumulate and transcribe the target gene p21. Blue light exposure leads to the export of the PMI-LEXY fusion into the cytosol, thereby Mdm2 is able to degrade p53 as in the absence of the peptide. This approach may be useful to study the effect of localized p53 activation within a tissue or organ.
11.1: Video‐Wall Matrix of Stereoscopic Displays using FPR

We built a video wall matrix of stereoscopic displays using film patterned retarder (FPR). We developed a model to calculate the vertical angular behavior of the FPR structure and compared it with conoscopic measurements. A second model developed to calculate viewing arena of stereo video walls with acceptable 3D crosstalk.
Velocities and Flux of the Filchner Ice Shelf and its Tributaries Determined from Speckle Tracking Interferometry

RÉSUMÉ Les vélocités de la plate-forme de glace Filchner et de ses glaciers tributaires sont déduites à partir d'une technique d'interférométrie radar satellitaire dite de suivi du chatoiement (speckle tracking). La méthode requiert un couplet cohérent de survols ROS, un modèle numérique d'élévation et, pour la glace flottante, une estimation de la différence de hauteur due à la marée. L'interférométrie du suivi du chatoiement a l'avantage de permettre l'estimation de la vitesse et de la direction de la glace à partir d'un seul couplet interférométrique et, avec une cohérence adéquate, elle est utile pour des surfaces de grande vélocité et des intervalles de survols éloignés. Les flux sont estimés au moyen des vélocités de la glace en conjonction avec les données d'épaisseur de glace dérivées d'un modèle d'équilibre hydrostatique. Ces flux sont fournis pour des transects en aval des lignes d'ancrage des glaciers tributaires et pour un transect proche de la bordure de la plate-forme de glace. Les calculs montrent que le flux proche de la bordure de la plate-forme de glace Filchner (∼75.3 km3/a) est comparable au flux estimé plus en amont. Toutefois, les erreurs dans les estimations (∼10 km3/a) empêchent toute conclusion ferme quant à l'équilibre de la plate-forme de glace ou à la surface de fonte ou d'accrétion sous-glaciaire. Assumant que les flux en amont reflètent le flux à travers les lignes d'ancrage, alors le glacier Recovery est le plus gros contributaire à la plate-forme de glace avec 48 % et le glacier Slessor est le second en importance avec 33 %. Le glacier Support Force et le Fondation Ice Stream contribuent tous deux dans une proportion de ∼7%. L'accumulation de la plate-forme de glace représente les 5 % restant.
High-latitude ionospheric response to a sudden impulse event during northward IMF conditions

A high-density structure under northward interplanetary magnetic field BZ conditions is identified at the Wind and IMP 8 satellites, both in the solar wind on August 22, 1995. A compression of the magnetosphere is observed by the GOES 7 magnetometer within a few minutes of the pressure increase encountering the magnetopause. The response of the high-latitude ionosphere is analyzed on the basis of ground-based magnetometer data. A comprehensive description of this response in the Northern Hemisphere is provided by more than 70 ground magnetometers. This data set is interpreted in terms of high-latitude ionospheric potential patterns by means of the assimilative mapping of ionospheric electrodynamics technique. Convection cells in the polar cap are formed and disappear on minute timescales in accordance with previous results. However, the high-latitude ionospheric ground magnetic signature does not match the interpretation as events of traveling convection vortices, as has been suggested by past studies.
Discordant paleomagnetic poles from the Canadian Coast Plutonic Complex: Regional tilt rather than large-scale displacement?

Stratigraphic, petrologic, and isotopic data indicate that parts of the Coast Plutonic Complex and the North Cascade Range have been tilted northeast-side-up by angles of {approximately}30{degree} about north-northwest-trending axes. These tilts can account for discordant paleomagnetic directions observed in mid-Cretaceous plutons from these regions without large-scale displacement relative to North America.
Significant Tsushima Warm Current during the Early-Middle Holocene along the San-in District Coast Inferred from Foraminiferal Profiles

日本海南部沿岸域における完新世初～中期の暖水系生物相と対馬海流の挙動との関係を理解するために, 出雲平野北西部と鳥取沖でそれぞれ採取された柱状試料HS02とGH87-2-308について, 浮遊性有孔虫化石を検討した. GH87-2-308における暖水系種Globigerinoides ruber の産出傾向は, 約8,300～8,000年前と約7,300～6,800年前の2つの時期に, 対馬海流の影響が強かったことを示す. 本種はHS02でも, 暖水系底生生物相が産出する約7,800年前の層準で見出される. 日本海のより沖合 (たとえば隠岐堆) の研究事例では, 暖水系微化石の産出は約7,300年前に普遍的なものの, 同様な普遍的産出は約8,300～7,800年前では不明瞭である. よって, 約8,300～7,800年前の対馬海流の影響は, 沿岸域で顕著に現れ, それが当時の山陰地方沿岸域における暖水系生物相の産出傾向を左右したと考えられる.
Extent of Access to Information and Communications Technology by the Rural Population of South Africa

This paper investigates the trends in access to Information and Communications Technology (ICT) in rural compared to the urban areas of South Africa. Using data from the South African Social Attitudes Survey (SASAS) covering the period from 2003 to 2009, the study found that access to both the ‘older’ and the ‘newer’ forms of ICTs has remained significantly lower (P < 0.001) in rural areas compared to urban areas. The paper then examines these trends in the context of the Department of Science and Technology's (DST) policies and strategies on the diffusion of science and technology in South Africa.
Shear wave splitting observations in the Chinese Tianshan orogenic belt

A linear array of 26 3‐component broadband digital stations across the Chinese Tianshan Orogenic Belt (CTOB) was deployed for 13 months to measure the shear wave splitting. Fast direction of teleseismic shear waves beneath the southern CTOB is NWW‐SEE and gradually turns into NEE‐SWW in the north. Delay times are 0.65∼1.48s with average value of 0.97 ± 0.15s and the maximum delay time is observed in the middle mountain and decrease in the south and the north. Fast directions are generally parallel to the strike of the orogenic belt, indicating that more than one hundred kilometers of upper mantle is involved in collisional deformation. Compared to other stations, change in fast direction for stations in the south and north ends of the array is probably resulted from subduction of the Tarim block and the Junggar block into the Tianshan range, respectively.
First record of a belemnite preserved with beaks, arms and ink sac from the Nusplingen Lithographic Limestone (Kimmeridgian, SW Germany)

Klug, C. , Schweigert, G. , Fuchs, D. & Dietl, G. 2009: First record of a belemnite preserved with beaks, arms and ink sac from the Nusplingen Lithographic Limestone (Kimmeridgian, SW Germany). Lethaia, 10.1111/j.1502-3931.2009. 00203.x A recent discovery of an unusually preserved belemnite from Nusplingen comprises the extraordinarily rare remains of beaks and nearly in situ arm hooks, as well as the ink sac and an incomplete phragmocone. So far, Hibolithes semisulcatus (Munster, 1830) is the only belemnite known from the Nusplingen Lithographic Limestone (Upper Jurassic, Late Kimmeridgian, Beckeri Zone, Ulmense Subzone; SW Germany) that has the same phragmocone shape and size, and thus we assign the new specimen to this taxon. The rostrum was probably lost due to a lethal predation attempt in which the prey was killed but not entirely eaten. For the first time a specimen reveals details of the belemnite beak morphology, which we compare with the beaks of other Jurassic coleoids. This specimen presently represents the only known rostrum-bearing belemnite of post-Toarcian age with preserved non-mineralized body parts. With the new discovery, Nusplingen now represents the only locality which has yielded complete beak apparatuses from all major Jurassic cephalopod groups. □Beaks, Belemnitida, Coleoidea, Germany, Late Jurassic, morphology, taphonomy.
New applications of the Poisson distribution in micropalaeontology: relationships between environmental variables and the Ammonia tepida distribution in the south‐western Spanish estuaries

The application of the Poisson regression to the populations of the benthic foraminifer Ammonia tepida collected in three south‐western Spanish estuaries permits to obtain a quantitative approach between some environmental variables and the number of individuals of this species. Although the three general models are unsatisfactory to predict the observed abundance of this micro‐organism, a partial statistical analysis permits to detect quantitatively the impact of each variable. This analysis indicates an increasing abundance from the high‐salt marshes to the subtidal channels and higher densities in those samples subjected to very euryhaline conditions. Increasing sand percentages show negative effects on the A. tepida abundance, whereas the silt contents do not affect significantly to this species and increasing organic carbon percentages have a small positive effect on the A. tepida densities.
Automatic HRR target recognition based on matrix pencil method and multiresolution neural network

With the increased availability of wideband radars, high resolution in range which means target discrimination can be possible. In this paper, a new approach for target recognition is proposed and tested on backscattering returns of high range resolution (HRR) radar. The matrix pencil method is used to extract scattering centers from full-polarization multi- frequency scattering returns. Feature vectors are constructed using the concept of a transient polarization response (TPR). The classification of feature vectors is performed by the multiresolution neural network that provides some properties superior to back-propagation neural networks. The algorithm is applied to the recognition of five scaled models of war aircrafts at different signal-to-noise ratios.
Effectiveness of Organic Matter Incorporation in Reducing Soil Compactibility

Incorporation of organic matter (OM) into soil can reduce its susceptibility to compaction. However, the significance of incorporated OM for different soil and soil water conditions is not well documented. We investigated the effectiveness of incorporated OM at different soil and soil water conditions and the OM effect on strength and structure recovery of compacted soils. A sandy soil (sandy Orthod), a silt loam (loamy Udalf), and a clay soil (clayey Umbrept) were amended with up to 80 g kg -1 of highly and slightly humified peat. The peat-soil mixtures were compacted at different water contents using the standard Proctor procedure. Soil strength was determined with a penetrometer. Structure recovery was determined by bulk density changes and disintegration of clods through wetting-drying cycles. For the cohesive silt loam and clay soils, OM was most effective at reducing compactibility at water contents lower than those for maximum Proctor compaction. For the sandy soil, OM was most effective at the Proctor-optimum water content. The slightly humified peat had a greater effect than the highly humified. We found that OM is most effective for soils with high compactibility. The maximum penetration resistance, P max , of the clay soil was reduced from 0.49 to 0.30 MPa, and that of the sandy soil increased from 0.64 to 1.08 MPa. For the silt loam, 30 g kg -1 peat content had the highest P max . After five wetting-drying cycles, bulk densities showed no significant differences among treatments. Clod disintegration was hindered by the OM incorporation. Although soil compactibility was reduced by OM incorporation, OM was more effective as soil compactibilty increased and at water contents lower than or close to the Proctor-optimum water content. Structure recovery of compacted soils was not improved. The penetration resistance after compaction is not consistently related to the incorporated OM.
Retrieval of Vertical Profiles of Liquid Water and Ice Content in Mixed Clouds from Doppler Radar and Microwave Radiometer Measurements

Abstract A new method to retrieve vertical profiles of liquid water content Mw(z), ice water content Mi(z), and ice particle size distribution Ni(D, z), (where D is the ice particle size and z the vertical coordinate) in mixed nonprecipitating clouds using the observations of a zenith-viewing Doppler radar and of a microwave radiometer is proposed. In this method, the profile of the vertical air velocity deduced from Doppler radar measurements is used to describe the rate of production by the updrafts of water. vapor in excess of saturation with respect to ice. Using a Zi − Mi power-law relation with an unknown linear parameter (let αi, be this parameter) and initially assuming that Zw is negligible with respect to Zi, (where Zw and Zi are the radar reflectivity factors of liquid water and ice particles respectively), the measured radar reflectivity factor profile Zm (≈ Zi) is inverted to estimate Ni(D, z). From Ni(D, z), the profile of the rate of water vapor that can be consumed by pure deposition on ic.
Formation and erosion of layered materials: Geologic and dust cycle history of eastern Arabia Terra, Mars

[1] Eastern Arabia Terra is mantled in a layer of dust a few centimeters to a meter thick, yet contains morphologic features that suggest a history of multiple events of deposition and consolidation of fine-grained material and a significant amount of erosion. Early in Martian history, this region was affected by volcanic and fluvial activity but has since been dominated by aeolian processes. Five craters in this region contain interior mound material that ranges in height from 1600 to 2100 m above the crater floor. The fluted erosional pattern and the thermal inertia are suggestive of a weakly indurated material, and the extensive layering implies that these mounds were formed by a repeated process or processes. Although these materials primarily occur within craters, there are materials outside craters that have similar erosional features and fine laminations, suggesting a more extensive deposit. The most likely process to form this material is the deposition and cementation of air fall dust and is potentially related to Martian obliquity changes. The significant amount of erosion of the intracrater mounds unit indicates a dramatic change from a depositional environment to an erosional regime over the past 106–108 years. Currently dust is accumulating in this region in years with planet-encircling dust events, but global circulation model results indicate that dust devils may be removing slight amounts of dust from Arabia Terra. These observations suggest that the thickness of the dust mantle may not be currently increasing and may instead be in equilibrium.
Evaluation of the spatial changes in seagrass cover in the lagoons of Lakshadweep islands, India, using IRS LISS III satellite images

A study was conducted in Lakshadweep islands to determine the feasibility of using Indian Remote Sensing (IRS) satellites for detecting changes in the seagrass from other coastal features. IRS ID and IRS P6 LISS III having spatial resolution of 23.5 m with lower cost compared to all other contemporary satellites with the same spatial resolution have not been widely used for monitoring the changes in seagrass cover. In this context, the present study attempted to explore the effectiveness of LISS III data for mapping seagrasses and to inform the international community about the usefulness of these low-cost imageries for coastal resource monitoring. Supervised classification and change detection studies found a significant decrease in seagrass cover of 73.03 ha in the Lakshadweep group of islands. An overall accuracy of 67.5% was obtained for the change maps, and seagrass cover and its changes vary at different islands.
Dynamic Kill of an Uncontrolled CO2 Well

In March 1982 a CO/sub 2/ well in the Sheep Mountain Unit, CO, blew out. This well was brought under control in early April 1982 by the dynamic injection of drag-reduced brine followed by mud. This paper discusses the events and field activities that followed the blowout and led to the successful kill operation. Also included is a discussion of two initial, unsuccessful kill attempts, associated mechanical problems, and the understanding gained therefrom. Analyses of wellbore and reservoir hydraulics led to an understanding of the freely flowing well. Injection of kill fluid down the drillpipe was possible, but the small pipe diameter, particularly that of the heavy wall drillpipe, significantly limited the rate of kill-fluid injection. The kill operation was further complicated by the high flow capacity of CO/sub 2/ from the reservoir. The high CO/sub 2/ flow rate efficiently gas-lifted the kill fluid up the annulus and thus tended to maintain a low bottomhole pressure (BHP). Further analysis of the hydraulics of the system suggested two alternatives for dynamically killing the well: (1) use of highly drag-reduced fluids of moderate density such as water or brine, and (2) use of non-drag-reduced mud with a density greater than about 18more » lbm/gal (2100 kg/m/sup 3/). The well was killed successfully with 10.5-lbm/gal (1260-kg/m/sup 3/) brine, which exhibited 72% drag reduction in surface lines and drillpipe at an injection rate of 60 bbl/min (570 m/sup 3//h). « less
