    Background El Nio/Southern Oscillation (ENSO) related climate anomalies have been shown to have an impact on infectious disease outbreaks. The Climate Prediction Center of the National Oceanic and Atmospheric Administration (NOAA/CPC) has recently issued an unscheduled El Nio advisory, indicating that warmer than normal sea surface temperatures across the equatorial eastern Pacific may have pronounced impacts on global tropical precipitation patterns extending into the northern hemisphere particularly over North America. Building evidence of the links between ENSO driven climate anomalies and infectious diseases, particularly those transmitted by insects, can allow us to provide improved long range forecasts of an epidemic or epizootic. We describe developing climate anomalies that suggest potential disease risks using satellite generated data. Results Sea surface temperatures (SSTs) in the equatorial east Pacific ocean have anomalously increased significantly during July October 2006 indicating the typical development of El Nio conditions. The persistence of these conditions will lead to extremes in global-scale climate anomalies as has been observed during similar conditions in the past. Positive Outgoing Longwave Radiation (OLR) anomalies, indicative of severe drought conditions, have been observed across all of Indonesia, Malaysia and most of the Philippines, which are usually the first areas to experience ENSO-related impacts. This dryness can be expected to continue, on average, for the remainder of 2006 continuing into the early part of 2007. During the period November 2006 January 2007 climate forecasts indicate that there is a high probability for above normal rainfall in the central and eastern equatorial Pacific Islands, the Korean Peninsula, the U.S. Gulf Coast and Florida, northern South America and equatorial east Africa. Taking into consideration current observations and climate forecast information, indications are that the following regions are at increased risk for disease outbreaks: Indonesia, Malaysia, Thailand and most of the southeast Asia Islands for increased dengue fever transmission and increased respiratory illness; Coastal Peru, Ecuador, Venezuela, and Colombia for increased risk of malaria; Bangladesh and coastal India for elevated risk of cholera; East Africa for increased risk of a Rift Valley fever outbreak and elevated malaria; southwest USA for increased risk for hantavirus pulmonary syndrome and plague; southern California for increased West Nile virus transmission; and northeast Brazil for increased dengue fever and respiratory illness. Conclusion The current development of El Nio conditions has significant implications for global public health. Extremes in climate events with above normal rainfall and flooding in some regions and extended drought periods in other regions will occur. Forecasting disease is critical for timely and efficient planning of operational control programs. In this paper we describe developing global climate anomalies that suggest potential disease risks that will give decision makers additional tools to make rational judgments concerning implementation of disease prevention and mitigation strategies.

    Geoanomalies generally are nonlinear, non-stationary and weak, especially in the land cover areas, however, the traditional methods of geoanomaly identification are usually based on linear theory. In past two decades, many power-law function models have been developed based on fractal concept in mineral exploration and mineral resource assessment, such that the density-area (C-A) model and spectrum-area model (S-A) suggested by Qiuming Cheng have played important roles in extracting geophysical and geochemical anomalies. Several power-law relationships are evident in geophysical potential fields, such as field value-distance, power spectrum-wave number as well as density-area models. The singularity index based on density-area model involves the first derivative transformation of the measure. Hence, we introduce the singularity analysis to develop a novel high-pass filter for extracting gravity and magnetic anomalies with the advantage of scale invariance. Furthermore, we suggest that the statistics of singularity indices can provide a new edge detection scheme for the gravity or magnetic source bodies. Meanwhile, theoretical magnetic anomalies are established to verify these assertions. In the case study from Nanling mineral district in south China and Qikou Depression in east China, compared with traditional geophysical filtering methods including multiscale wavelet analysis and total horizontal gradient methods, the singularity method enhances and extracts the weak anomalies caused by buried magmatic rocks more effectively, and provides more distinct boundary information of rocks. Moreover, the singularity mapping results have good correspondence relationship with both the outcropping rocks and known mineral deposits to support future mineral resource exploration. The singularity method based on fractal analysis has potential to be a new useful theory and technique for processing gravity and magnetic anomaly data.

  5. Thermodynamic, dynamic, and structural anomalies for shoulderlike potentials.

    2009-09-01

    Using molecular dynamic simulations we study a family of continuous core-softened potentials consisting of a hard core, a shoulder at closest distances, and an attractive well at further distance. The repulsive shoulder and the well distances represent two length scales. We show that if the first scale, the shoulder, is repulsive or has a small well, the potential has a region in the pressure-temperature phase diagram with density, diffusion, and structural anomalies. However, if the closest scale becomes a deep well, the regions in the pressure-temperature phase diagram where the three anomalies are present shrink and disappear. This result helps in defining two length scales potentials that exhibit anomalies. PMID:19739858

  6. The Age Specific Incidence Anomaly Suggests that Cancers Originate During Development

    NASA Astrophysics Data System (ADS)

    Brody, James P.

    The accumulation of genetic alterations causes cancers. Since this accumulation takes time, the incidence of most cancers is thought to increase exponentially with age. However, careful measurements of the age-specific incidence show that the specific incidence for many forms of cancer rises with age to a maximum, and then decreases. This decrease in the age-specific incidence with age is an anomaly. Understanding this anomaly should lead to a better understanding of how tumors develop and grow. Here we derive the shape of the age-specific incidence, showing that it should follow the shape of a Weibull distribution. Measurements indicate that the age-specific incidence for colon cancer does indeed follow a Weibull distribution. This analysis leads to the interpretation that for colon cancer two subpopulations exist in the general population: a susceptible population and an immune population. Colon tumors will only occur in the susceptible population. This analysis is consistent with the developmental origins of disease hypothesis and generalizable to many other common forms of cancer.

  8. Laboratory investigation of lunar surface electric potentials in magnetic anomaly regions

    2015-06-01

    To gain insight into lunar surface charging in the magnetic anomaly regions, we present the results of laboratory experiments with a flowing plasma engulfing a magnetic dipole field above an insulating surface. When the dipole moment is perpendicular to the surface, large positive potentials (close to ion flow energies in eV) are measured on the surface in the dipole lobe regions, charged by the unmagnetized ions while the electrons are magnetically excluded. The potential decreases exponentially with distance from the surface on the ion (flow) Debye length scale. The surface potentials become much smaller when the dipole moment is parallel to the surface, likely due to collisionality. We discuss the implications of our laboratory results for the lunar surface charging in the magnetic anomaly regions, suggesting that the surface potential may be much higher than the generally expected several volts positive due to photoemission.

  9. Precise Synaptic Efficacy Alignment Suggests Potentiation Dominated Learning

    2016-01-01

    Recent evidence suggests that parallel synapses from the same axonal branch onto the same dendritic branch have almost identical strength. It has been proposed that this alignment is only possible through learning rules that integrate activity over long time spans. However, learning mechanisms such as spike-timing-dependent plasticity (STDP) are commonly assumed to be temporally local. Here, we propose that the combination of temporally local STDP and a multiplicative synaptic normalization mechanism is sufficient to explain the alignment of parallel synapses. To address this issue, we introduce three increasingly complex models: First, we model the idealized interaction of STDP and synaptic normalization in a single neuron as a simple stochastic process and derive analytically that the alignment effect can be described by a so-called Kesten process. From this we can derive that synaptic efficacy alignment requires potentiation-dominated learning regimes. We verify these conditions in a single-neuron model with independent spiking activities but more realistic synapses. As expected, we only observe synaptic efficacy alignment for long-term potentiation-biased STDP. Finally, we explore how well the findings transfer to recurrent neural networks where the learning mechanisms interact with the correlated activity of the network. We find that due to the self-reinforcing correlations in recurrent circuits under STDP, alignment occurs for both long-term potentiation- and depression-biased STDP, because the learning will be potentiation dominated in both cases due to the potentiating events induced by correlated activity. This is in line with recent results demonstrating a dominance of potentiation over depression during waking and normalization during sleep. This leads us to predict that individual spine pairs will be more similar after sleep compared to after sleep deprivation. In conclusion, we show that synaptic normalization in conjunction with coordinated potentiation—in this case, from STDP in the presence of correlated pre- and post-synaptic activity—naturally leads to an alignment of parallel synapses.

  10. Organized convection ahead of a potential vorticity anomaly

    2015-04-01

    We present a case study of a convective band that intensified ahead of an upper level trough on September 16 2011, distinguishing the role of the upper-level potential vorticity anomaly from that of low-level forcing. The event occurred during an Intensive Observing Period of two field campaigns, providing the study with detailed measurements from the UK's FAAM research aircraft together with intensive ground-based observations. The WRF model, initialized with ECMWF analyses, was able to simulate the observed structure of the band very well, allowing its development to be analyzed in detail. The band intensified as the result of the merger of two convergence lines which originated in a frontal structure over the Atlantic the previous day, with its morphology influenced by two upper-level features: the remnants of a tropopause fold which capped convection over the south of the band, and a reduction in upper tropospheric static stability over the north of the band which enabled the convection to reach the tropopause. The cause of the band was therefore the low-level forcing (lift) which was manifest as a sharp line of veering wind below 2 km. Accurate forecasting of events such as this require such small-scale boundary-layer features to be accurately captured in the model analyses.

  11. Simulations suggest pharmacological methods for rescuing long-term potentiation.

    Congenital cognitive dysfunctions are frequently due to deficits in molecular pathways that underlie the induction or maintenance of synaptic plasticity. For example, Rubinstein-Taybi syndrome (RTS) is due to a mutation in cbp, encoding the histone acetyltransferase CREB-binding protein (CBP). CBP is a transcriptional co-activator for CREB, and induction of CREB-dependent transcription plays a key role in long-term memory (LTM). In animal models of RTS, mutations of cbp impair LTM and late-phase long-term potentiation (LTP). As a step toward exploring plausible intervention strategies to rescue the deficits in LTP, we extended our previous model of LTP induction to describe histone acetylation and simulated LTP impairment due to cbp mutation. Plausible drug effects were simulated by model parameter changes, and many increased LTP. However no parameter variation consistent with a effect of a known drug class fully restored LTP. Thus we examined paired parameter variations consistent with effects of known drugs. A pair that simulated the effects of a phosphodiesterase inhibitor (slowing cAMP degradation) concurrent with a deacetylase inhibitor (prolonging histone acetylation) restored normal LTP. Importantly these paired parameter changes did not alter basal synaptic weight. A pair that simulated the effects of a phosphodiesterase inhibitor and an acetyltransferase activator was similarly effective. For both pairs strong additive synergism was present. The effect of the combination was greater than the summed effect of the separate parameter changes. These results suggest that promoting histone acetylation while simultaneously slowing the degradation of cAMP may constitute a promising strategy for restoring deficits in LTP that may be associated with learning deficits in RTS. More generally these results illustrate how the strategy of combining modeling and empirical studies may provide insights into the design of effective therapies for improving long-term synaptic plasticity and learning associated with cognitive disorders.

  12. A new method of interpreting self-potential anomalies of two-dimensional inclined sheets

    2005-06-01

    A new method of interpreting self-potential anomalies of inclined sheet-like bodies of infinite strike length is presented in this study. In contrast to conventional schemes, the method does not explicitly make use of the magnitudes of the anomaly values during inversion. But, positions of a pair of points, at which the anomaly values differ from each other by a constant magnitude, are selected to construct some linear equations. The coefficients of these equations are functions of the model parameters, and hence the latter are solved from these coefficients. The method can be extended to gravity and magnetic anomalies of various models of simple geometry.

  13. Water-like Anomalies and Phase Behavior of a Pair Potential that Stabilizes Diamond.

    Water, silicon, silica, and other liquids that favor tetrahedral order display thermodynamic, dynamic, and structural anomalies in the pressure range in which they form tetrahedrally coordinated crystals. The tetrahedral order in these liquids is induced by anisotropic hydrogen bonding or covalent interactions, or, in ionic melts, by an appropriate size ratio of the ions. Simple isotropic two-length scale models have been extensively used to understand the origin of anomalies in complex liquids. However, single-component isotropic liquids characterized to date generally do not stabilize tetrahedral crystals, and in the few cases that they do, it was found that the liquids do not display anomalies in the region of the tetrahedral crystal. This poses the question of whether it is possible for isotropic pair potentials to display water-like phase behavior and anomalies. In this work, we use molecular dynamics simulations to investigate the phase behavior and the existence and loci of anomalies of a single-component purely repulsive isotropic pair potential that stabilizes diamond in the ground state over a wide range of pressures. We demonstrate that, akin to water, silica, and silicon, the isotropic potential of Marcotte, Stillinger, and Torquato (MST) presents structural, dynamic, and thermodynamic anomalies in the region of stability of the tetrahedral crystal. The regions of anomalies of MST are nested in the T-p plane following the same hierarchy as in silica: the region of diffusional anomalies encloses the region of structural anomalies, which in turn contains the region of thermodynamic anomalies. To our knowledge, MST is the first example of pair potential for which water-like anomalies are associated with the formation of tetrahedral order. PMID:26426477

  15. Evaluating Cenozoic equatorial sediment deposition anomalies for potential paleoceanographic and Pacific plate motion applications

    Mitchell, Neil C.; Dubois, Nathalie

    2014-03-01

    If equatorial sediments form characteristic deposits around the equator, they may help to resolve the amount of northwards drift of the Pacific tectonic plate. Relevant to this issue, it has been shown that 230Th has been accumulating on the equatorial seabed faster than its production from radioactive decay in the overlying water column during the Holocene (Marcantonio et al. in Paleoceanography 16:260-267, 2001). Some researchers have argued that this reflects the deposition of particles with adsorbed 230Th carried by bottom currents towards the equator ("focusing"). If correct, this effect may combine with high pelagic productivity, which is also centered on the equator, to yield a characteristic signature of high accumulation rates marking the paleoequator in older deposits. Here we evaluate potential evidence that such an equatorial feature existed in the geological past. Seismic reflection data from seven meridional transects suggest that a band of equatorially enhanced accumulation of restricted latitude was variably developed, both spatially and temporally. It is absent in the interval 14.25-20.1 Ma but is well developed for the interval 8.55-14.25 Ma. We also examined eolian dust accumulation rate histories generated from scientific drilling data. A dust accumulation rate anomaly near the modern equator, which is not obviously related to the inter-tropical convergence zone, is interpreted as caused by focusing. Accumulation rates of Ba and P2O5 (proxies of export production) reveal a static equatorial signature, which suggests that the movement of the Pacific plate over the period 10-25 Ma was modest. The general transition from missing to well-developed focusing signatures around 14.25 Ma in the seismic data coincides with the mid-Miocene development of the western boundary current off New Zealand. This current supplies the Pacific with deep water from Antarctica, and could therefore imply a potential paleoceanographic or paleoclimatic origin. At 10.05-14.25 Ma, the latitudes of the seismic anomalies are up to ~2 different from the paleoequator predicted by Pacific plate-hotspot models, suggesting potentially a small change in the hotspot latitudes relative to the present day (although this inference depends on the precise form of the deposition around the equator). The Ba and P2O5 anomalies, on the other hand, are broadly compatible with plate models predicting slow northward plate movement over 10-25 Ma.

    2014-05-01

    Structural geological models are often based on the integration of different geophysical datasets. During the last years an increasing interest in the potential field methods, i.e. gravimetry and magnetic, can be observed, even though data acquisition can cause considerable costs and logistic effort. Therefore, the specific advantages and disadvantages of the different methods were analyzed. In a case study, which was conducted in cooperation with RWE Dea and which is located in northern Germany, it was studied to which level of detail gravity and magnetic anomalies can be interpreted jointly by 3D forward modelling. Special attention was paid to the individual residuals, i.e. those parts of the gravity and magnetic anomalies which could not be interpreted satisfactorily by the joint structural / physical model. In a subsequent stage of the workflow this information was analyzed individually for each dataset to improve the geological interpretation and to identify and localize the sources of the anomalies in more detail. For the discussed study several potential field datasets of different resolution were available, which were first analyzed by means of field transformation. While the gravity anomalies are mainly related to the occurrence of salt structures, the magnetic anomalies seem to be controlled by deep structures, most probably by the magnetic basement. Some local magnetic anomalies with amplitudes of less than 10 nT can be related to the rim synclines of the salt structures as well as to buried Pleistocene subglacial valleys. 3D forward models, constrained by existing structural information and rock physical data, have shown that, e.g., a common fitting of both anomaly fields is not possible if homogenous densities and magnetizations are assigned to the different lithological units and while considering the geometry of the source bodies to be the same for both potential field anomalies. To explain the magnetic anomalies a more detailed differentiation of the source bodies in terms of thin layers is required, while for the interpretation of the gravity anomalies vertical density gradients must be considered for specific lithologies. Furthermore, from the magnetic anomalies ideas about the maximum depth of source bodies can be derived.

  18. Nonrelativistic inverse square potential, scale anomaly, and complex extension

    Moroz, Sergej Schmidt, Richard

    2010-02-15

    The old problem of a singular, inverse square potential in nonrelativistic quantum mechanics is treated employing a field-theoretic, functional renormalization method. An emergent contact coupling flows to a fixed point or develops a limit cycle depending on the discriminant of its quadratic beta function. We analyze the fixed points in both conformal and nonconformal phases and perform a natural extension of the renormalization group analysis to complex values of the contact coupling. Physical interpretation and motivation for this extension is the presence of an inelastic scattering channel in two-body collisions. We present a geometric description of the complex generalization by considering renormalization group flows on the Riemann sphere. Finally, using bosonization, we find an analytical solution of the extended renormalization group flow equations, constituting the main result of our work.

  19. Spherical harmonic expansions of the Earth's gravitational potential to degree 360 using 30' mean anomalies

    Two potential coefficient fields that are complete to degree and order 360 have been computed. One field (OSU86E) excludes geophysically predicted anomalies while the other (OSU86F) includes such anomalies. These fields were computed using a set of 30' mean gravity anomalies derived from satellite altimetry in the ocean areas and from land measurements in North America, Europe, Australia, Japan and a few other areas. Where no 30' data existed, 1 deg x 1 deg mean anomaly estimates were used if available. No rigorous combination of satellite and terrestrial data was carried out. Instead advantage was taken of the adjusted anomalies and potential coefficients from a rigorous combination of the GEML2' potential coefficient set and 1 deg x 1 deg mean gravity anomalies. The two new fields were computed using a quadrature procedure with de-smoothing factors. The spectra of the new fields agree well with the spectra of the fields with 1 deg x 1 deg data out to degree 180. Above degree 180 the new fields have more power. The fields have been tested through comparison of Doppler station geoid undulations with undulations from various geopotential models. The agreement between the two types of undulations is approximately + or - 1.6 m. The use of a 360 field over a 180 field does not significantly improve the comparison. Instead it allows the comparison to be done at some stations where high frequency effects are important. In addition maps made in areas of high frequency information (such as trench areas) clearly reveal the signal in the new fields from degree 181 to 360.

The general derivative of chemical <span class="hlt">potential</span> permits thermal variations which give rise to the thermoelectric effect. It also accounts for nonideal solution behavior. An equation describing electric field strength is similarly derived with the additional assumption of electrical neutrality in the fluid Planck approximation. The Planck approximation implies that self-<span class="hlt">potential</span> (SP) is caused only by local sources and also that the electric field strength has only first order spatial variations. The derived relationships are applied to the NaCl-KCl concentration cell with predicted and measured voltages agreeing within 0.4 mV. The relationships are also applied to the Long Valley and Yellowstone geothermal systems. There is a high degree of correlation between predicted and measured SP response for both systems, giving supporting evidence for the validity of the approach. Predicted SP amplitude exceeds measured in both cases; this is a possible consequence of the Planck approximation. Electrochemical sources account for more than 90% of the predicted response in both cases while thermoelectric mechanisms account for the remaining 10%; electrokinetic effects are not considered. Predicted electrochemical and thermoelectric voltage coupling coefficients are comparable to values measured in the laboratory. The derived relationships are also applied to arbitrary distributions of temperature and fluid composition to investigate the geometric diversity of observed SP <span class="hlt">anomalies</span>. Amplitudes predicted for hypothetical saline spring and hot spring environments are less than 40 mV. In contrast, hypothetical near surface steam zones generate very large amplitudes, over 2 V in one case. These results should be viewed with some caution due to the uncertain validity of the Planck approximation for these conditions. All amplitudes are controlled by electrochemical mechanisms. Polarities are controlled by the curvature of the concentration or thermal profile. Concave upward thermal profiles produce positive <span class="hlt">anomalies</span>, for constant fluid concentrations, whereas concave upward concentration profiles produce negative <span class="hlt">anomalies</span>.

Throughout summer and fall 2014 and winter 2015, El Nio Watch, issued by the US National Oceanic and Atmospheric Administration, assessed likely El Nio development during the Northern Hemisphere fall and winter, persisting into spring 2015. Methods: We identified geographic regions where environmental conditions may increase infectious disease transmission if the predicted El Nio occurs using El Nio indicators (Sea Surface Temperature [SST], Outgoing Longwave Radiation [OLR], and rainfall <span class="hlt">anomalies</span>) and literature review of El Nio-infectious disease associations. Results: SSTs in the equatorial Pacific and western Indian Oceans were anomalously elevated during August-October 2014, consistent with a developing weak El Nio event. Teleconnections with local climate is evident in global precipitation patterns, with positive OLR <span class="hlt">anomalies</span> (drier than average conditions) across Indonesia and coastal southeast Asia, and negative <span class="hlt">anomalies</span> across northern China, the western Indian Ocean, central Asia, north-central and northeast Africa, Mexico/Central America, the southwestern United States, and the northeastern and southwestern tropical Pacific. Persistence of these conditions could produce environmental settings conducive to increased transmission of cholera, dengue, malaria, Rift Valley fever, and other infectious diseases in regional hotspots as during previous El Nio events. Discussion and Conclusions: The current development of weak El Nio conditions may have significant <span class="hlt">potential</span> implications for global public health in winter 2014-spring 2015. Enhanced surveillance and other preparedness measures in predicted infectious disease hotspots could mitigate health impacts.

E.; Jachens, R. C.; Clynne, M. A.; Muffler, L. J.</p> <p>2013-12-01</p> <p>Interpretation of aeromagnetic and new gravity data supports the earlier hypothesis by Blakely et al. (1997) that Quaternary faulting is influenced by preexisting basement structure in the region between Mt. Shasta and Lassen Peak volcanoes. Analysis of aeromagnetic data and more than 800 new gravity measurements provide structural detail within the Hat Creek graben and along the northeast-striking gravity high located between the two volcanoes. Late Cenozoic volcanic rocks coincide with short-wavelength magnetic <span class="hlt">anomalies</span> of both normal and reversed polarity, whereas a markedly smoother magnetic field overlies Paleozoic basement rocks and early Cenozoic cover. The boundary between the two magnetic patterns is roughly parallel to the southeast boundary of the gravity high, which coincides with a change in strike and distribution of Quaternary faults. The linear northeast-trending boundary of the magnetic pattern <span class="hlt">suggests</span> that no significant dextral shear (more than 2 km) associated with the Walker Lane has propagated from the southeast through this region. Although the magnetic field over the Cenozoic volcanic rocks is complex, the Hat Creek fault, which displaces basalt dated at 24 × 6 ka (Turrin et al., 2007) and which forms the eastern margin of the Hat Creek graben, is marked by the eastern edge of a 30-km-long north-trending magnetic high. The western edge of the magnetic high, however, does not coincide with the western margin of the graben, but instead bisects the down-dropped block. This pattern is mimicked in the gravity field, where the eastern part of the graben has gravity values 5-6 mGal higher than the western part of the graben. Preliminary modeling <span class="hlt">suggests</span> that the Hat Creek fault may have as much as 2 km of near-vertical offset to account for the gravity <span class="hlt">anomaly</span> across the fault. At the northern end of the graben at about latitude 41° 52.5'N, the Hat Creek fault is expressed by many short faults distributed between Burney and Pittville. Here both the gravity and magnetic character changes, with the disappearance of the gravity high along the eastern margin of the graben and a shift to the northeast in the strike of the magnetic high. The gravity low that spans the graben at this latitude coincides with the present topographic lowland, <span class="hlt">suggesting</span> that this area has been low-lying for as much as 1.5 million years, based on extensive diatomite lake beds (Page and Renne, 1994). This change in fault character coincides with a northeast-striking alignment of prominent, semicircular magnetic lows that we interpret as small calc-alkaline volcanoes erupted during reversed polarity epochs. These volcanoes appear to be concealed beneath younger volcanic flows. The distribution of these older volcanoes may have been influenced by the preexisting crustal structure delineated by the northeast-striking gravity high discussed by Blakely et al. (1997). This fundamental crustal change also may account for the westward jump of the 2-3 Ma Cascade arc axis to its present location.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://cfpub.epa.gov/si/si_public_record_report.cfm?dirEntryId=51063&keyword=erp&actType=&TIMSType=+&TIMSSubTypeID=&DEID=&epaNumber=&ntisID=&archiveStatus=Both&ombCat=Any&dateBeginCreated=&dateEndCreated=&dateBeginPublishedPresented=&dateEndPublishedPresented=&dateBeginUpdated=&dateEndUpdated=&dateBeginCompleted=&dateEndCompleted=&personID=&role=Any&journalID=&publisherID=&sortBy=revisionDate&count=50&CFID=56418237&CFTOKEN=27521813','EPA-EIMS'); return false;" href="http://cfpub.epa.gov/si/si_public_record_report.cfm?dirEntryId=51063&keyword=erp&actType=&TIMSType=+&TIMSSubTypeID=&DEID=&epaNumber=&ntisID=&archiveStatus=Both&ombCat=Any&dateBeginCreated=&dateEndCreated=&dateBeginPublishedPresented=&dateEndPublishedPresented=&dateBeginUpdated=&dateEndUpdated=&dateBeginCompleted=&dateEndCompleted=&personID=&role=Any&journalID=&publisherID=&sortBy=revisionDate&count=50&CFID=56418237&CFTOKEN=27521813"><span id="translatedtitle"><span class="hlt">SUGGESTIONS</span> FOR COLLECTION AND REPORTING OF CHEMOSENSORY (OLFACTORY) EVENT-RELATED <span class="hlt">POTENTIALS</span></span></a></p> <p><a target="_blank" href="http://oaspub.epa.gov/eims/query.page">EPA Science Inventory</a></p> <p></p> <p></p> <p>Chemosensory event-related <span class="hlt">potentials</span> hold great promise for furthering understanding of the olfactory system and the processing of olfactory information. ollection of this type of data has been difficult and <span class="hlt">suggestions</span> are presented to aid investigators new to this field. ugges...</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.ncbi.nlm.nih.gov/pubmed/21198001','PUBMED'); return false;" href="http://www.ncbi.nlm.nih.gov/pubmed/21198001"><span id="translatedtitle">Effects of the attractive interactions in the thermodynamic, dynamic, and structural <span class="hlt">anomalies</span> of a two length scale <span class="hlt">potential</span>.</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>da Silva, Jonathas Nunes; Salcedo, Evy; de Oliveira, Alan Barros; Barbosa, Marcia C</p> <p>2010-12-28</p> <p>Using molecular dynamic simulations, we study a system of particles interacting through a continuous core-softened <span class="hlt">potentials</span> consisting of a hard core, a shoulder at closest distances, and an attractive well at further distance.

P.</p> <p>2008-01-01</p> <p>Background and Aims In neotropical forests, very small-seeded pioneer species (<01 mg seed mass) recruit preferentially in small tree fall gaps and at gap edges, but large-seeded pioneers do not. Since water availability is related to gap size, these differences in microsite preference may reflect in part species-specific differences in germination at reduced water <span class="hlt">potentials</span>. Methods For 14 neotropical pioneer species, the hypothesis is tested that small-seeded species, with shallow initial rooting depths, reduce the risks associated with desiccation by germinating more slowly and at higher water <span class="hlt">potentials</span> than large-seeded species. Key Results Germination occurred both more quickly and at lower water <span class="hlt">potentials</span> with increasing seed mass. For example, Ochroma pyramidale (seed mass 55 mg) had a time to 50 % germination (T50) of 28 d and a median base <span class="hlt">potential</span> for germination (?b50) of ?18 MPa while Clidemia quinquenervia (seed mass 0017 mg) had a T50 of 176 d and ?b50 of ?11 MPa. Conclusions These data <span class="hlt">suggest</span> that small-seeded species germinate only in comparatively moist microsites, such as small canopy gaps, which may reduce the risk of drought-induced mortality. Conversely, large-seeded species are able to germinate in the drier environment of large gaps, where they benefit by enhanced seedling growth in a high irradiance environment. The positive association of seed size and canopy gap size for optimal seedling establishment is maintained by differential germination responses to soil water availability coupled with the scaling of radicle growth rate and seed size, which collectively confer greater drought tolerance on large-seeded species.

As a topical formulation, trifluralin is also effective in vivo (in BALB/c mice) against Leishmania major and Leishmania mexicana.

However, researchers have <span class="hlt">suggested</span> that the activity of trifluralin is due to an impurity or contaminant, not to trifluralin itself. We have pursued this lead and identified the structure of the active impurity. This compound, chloralin, is 100 times more active than trifluralin. On the basis of its structure, we developed a rational structure-activity model for chloralin. Using this model, we have successfully predicted and tested active analogs in a Leishmania promastigote assay; thus, we have identified the putative mechanism of action of this class of drugs in Leishmania species. <span class="hlt">Potentially</span>, this will allow the design of noncarcinogenic, active drugs.

Drosophila montana, a D. virilis group species found in high latitude boreal forests in Nearctic and Palearctic regions around the globe, could be an excellent model system for studying the early stages of speciation, as a wealth of information concerning this species' ecology, mating system, life history, genetics and phylogeography is available. However, reproductive barriers between populations have hereto not been investigated. Results We report both pre- and postmating barriers to reproduction between flies from European (Finnish) and North American (Canadian) populations of Drosophila montana. Using a series of mate-choice designs, we show that flies from these two populations mate assortatively (i.e., exhibit significant sexual isolation) while emphasizing the importance of experimental design in these kinds of studies. We also assessed <span class="hlt">potential</span> postmating isolation by quantifying egg and progeny production in intra- and interpopulation crosses and show a significant one-way reduction in progeny production, affecting both male and female offspring equally. Conclusion We provide evidence that allopatric D. montana populations exhibit reproductive isolation and we discuss the <span class="hlt">potential</span> mechanisms involved. Our data emphasize the importance of experimental design in studies on premating isolation between recently diverged taxa and <span class="hlt">suggest</span> that postmating barriers may be due to postcopulatory-prezygotic mechanisms. D. montana populations seem to be evolving multiple barriers to gene flow in allopatry and our study lays the groundwork for future investigations of the genetic and phenotypic mechanisms underlying these barriers.

The combination of these virulence gene alleles and ribotype patterns separated L. monocytogenes into three distinct lineages. While distinct hly and inlA alleles were generally found to cluster into these three lineages, actA alleles segregated independently.

Previous studies on BoNTs have generally utilized the major SNARE homologues expressed in brain (VAMP2, syntaxin 1, and SNAP-25). However, BoNTs target peripheral motor neurons and cause death by paralyzing respiratory muscles such as the diaphragm. Here we report that VAMP1, but not VAMP2, is the SNARE homologue predominantly expressed in adult rodent diaphragm motor nerve terminals and in differentiated human motor neurons. In contrast to the highly conserved VAMP2, BoNT-resistant variations in VAMP1 are widespread across vertebrates. In particular, we identified a polymorphism at position 48 of VAMP1 in rats, which renders VAMP1 either resistant (I48) or sensitive (M48) to BoNT/D. Taking advantage of this finding, we showed that rat diaphragms with I48 in VAMP1 are insensitive to BoNT/D compared to rat diaphragms with M48 in VAMP1. This unique intra-species comparison establishes VAMP1 as a physiological toxin target in diaphragm motor nerve terminals, and demonstrates that the resistance of VAMP1 to BoNTs can underlie the insensitivity of a species to members of BoNTs. Consistently, human VAMP1 contains I48, which may explain why humans are insensitive to BoNT/D. Finally, we report that residue 48 of VAMP1 varies frequently between M and I across seventeen closely related primate species, <span class="hlt">suggesting</span> a <span class="hlt">potential</span> selective pressure from members of BoNTs for resistance in vertebrates.

While aboveground Ag accumulation was highest in B. juncea (4.60 ± 2.58 mg kg(-1)), lower levels were also measured in M. sativa and F. arundinacea. Cu accumulation was observed in all species, but only in underground parts, and was highest in F. arundinacea (269.20 ± 74.75 mg kg(-1)), with a bioconcentration factor of 13.85. Salix miyabeana was found to have the highest Zn aerial tissue concentration (119.96 ± 20.04 mg kg(-1)). Because of its high Ag uptake, the remediation <span class="hlt">potential</span> of B. juncea should be evaluated more extensively on the site from which we excavated the soil for this study. Given the multiple forms of contamination on the site and the differential specie-related uptake evident in our findings, we hypothesize that an optimal plantation allowing expression of complementary remediation functions would include B. juncea for extraction of Ag, in combination with F. arundinacea for stabilization of Cu and S. miyabeana for extraction of Zn.

In humans, these transporters participate in key physiological processes and are also, as in the case of members of the organic anion transporter (OAT) family, of pharmaceutical interest. Recently, crystal structures of two bacterial representatives of the MFS family--the glycerol-3-phosphate transporter (GlpT) and lac-permease (LacY)--have been solved and, because of assumptions regarding the high structural conservation of this family, there is hope that the results can be applied to mammalian transporters as well. Based on crystallography, it has been <span class="hlt">suggested</span> that a major conformational "switching" mechanism accounts for ligand transport by MFS proteins. This conformational switch would then allow periodic changes in the overall transporter configuration, resulting in its cyclic opening to the periplasm or cytoplasm. Following this lead, we have modeled a possible "switch" mechanism in GlpT, using the concept of rotation of protein domains as in the DynDom program17 and membranephilic constraints predicted by the MAPAS program.(23) We found that the minima of energies of intersubunit interactions support two alternate positions consistent with their transport properties. Thus, for GlpT, a "tilt" of 9 degrees -10 degrees rotation had the most favorable energetics of electrostatic interaction between the two halves of the transporter; moreover, this confirmation was sufficient to <span class="hlt">suggest</span> transport of the ligand across the membrane. We conducted steered molecular dynamics simulations of the GlpT-ligand system to explore how glycerol-3-phosphate would be handled by the "tilted" structure, and obtained results generally consistent with experimental mutagenesis data. While biochemical data remain most consistent with a single-site alternating access model, our results raise the possibility that, while the "rocker switch" may apply to certain MFS transporters, intermediate "tilted" states may exist under certain circumstances or as transitional structures. Although wet lab experimental confirmation is required, our results <span class="hlt">suggest</span> that transport mechanisms in this transporter family should probably not be assumed to be conserved simply based on standard structural homology considerations. Furthermore, steered molecular dynamics elucidating energetic interactions of ligands with amino acid residues in an appropriately modeled transporter may have predictive value in understanding the impact of mutations and/or polymorphisms on transporter function.

Certain radiologic findings reported in this condition overlap with those caused by child abuse. However, cervical spine defects simulating cervical spine fracture, a known result of nonaccidental pediatric trauma, have not been reported previously in this illness. Objective To assess the frequency of cervical spine <span class="hlt">anomalies</span> in Menkes disease after discovery of an apparent C2 posterior arch defect in a child participating in a clinical trial. Materials and methods We examined cervical spine radiographs obtained in 35 children with Menkes disease enrolled in a clinical trial at the National Institutes of Health Clinical Center. Results Four of the 35 children with Menkes disease had apparent C2 posterior arch defects consistent with spondylolysis or incomplete/delayed ossification. Conclusion Defects in C2 were found in 11% of infants and young children with Menkes disease. Discovery of cervical spine defects expands the spectrum of radiologic findings associated with this condition. As with other skeletal abnormalities, this feature simulates nonaccidental trauma. In the context of Menkes disease, suspicions of child abuse should be considered cautiously and tempered by these findings to avoid unwarranted accusations.

The low-molecular weight oligomers of Aβ aggregates (2 to 30 mers) are known to be the primary neurotoxic agents whose mechanisms of cellular toxicity and synaptic dysfunction have received substantial attention in the recent years. However, how these toxic agents proliferate and induce widespread amyloid deposition throughout the brain, and what mechanism is involved in the amplification and propagation of toxic oligomer species, are far from clear. Emerging evidence based on transgenic mice models indicates a transmissible nature of Aβ aggregates and implicates a prion-like mechanism of oligomer propagation, which manifests as the dissemination and proliferation of Aβ toxicity. Despite accumulating evidence in support of a transmissible nature of Aβ aggregates, a clear, molecular-level understanding of this intriguing mechanism is lacking. Recently, we reported the characterization of unique replicating oligomers of Aβ42 (12-24 mers) in vitro called Large Fatty Acid-derived Oligomers (LFAOs) (Kumar et al., 2012, J. Biol. Chem). In the current report, we establish that LFAOs possess physiological activity by activating NF-κB in human neuroblastoma cells, and determine the experimental parameters that control the efficiency of LFAO replication by self-propagation. These findings constitute the first detailed report on monomer - oligomer lateral propagation reactions that may constitute <span class="hlt">potential</span> mechanism governing transmissibility among Aβ oligomers. These data support the previous reports on transmissible mechanisms observed in transgenic animal models.

Remarkably, prostratin is also able to inhibit de novo human immunodeficiency virus type 1 (HIV-1) infection yet up-regulate viral expression from latent proviruses. Prostratin's lack of tumor promotion, coupled with its ability to block viral spread yet induce latent proviral expression, prompted studies to determine whether this compound could serve as an inductive adjuvant therapy for patients treated with highly active antiretroviral therapy (HAART). The current experiments indicate that prostratin is a potent mitogen for mononuclear phagocytes possessing many of the activities of phorbol myristate acetate (PMA) with notable functional differences. Prostratin, like PMA, accelerates differentiation of the myeloid cell-lines, HL-60 and THP-1, as well as mononuclear phagocytes from bone marrow and peripheral blood. Enzyme-linked immunosorbent assay and gene array analyses indicate significant changes in the expression of proteins and messenger RNA after treatment of cells with prostratin, consistent with phagocyte activation and differentiation. Prostratin blocks HIV-1 infection relating to down-regulation of CD4 receptor expression. The array analysis indicates a similar down-regulation of the HIV-1 coreceptors, CXCR4 and CCR5, and this may also reduce viral infectivity of treated host cells. Finally, prostratin is capable of up-regulating HIV-1 expression from CD8+ T lymphocyte-depleted peripheral blood mononuclear cells of patients undergoing HAART. This novel observation <span class="hlt">suggests</span> the agent may be an excellent candidate to augment HAART by inducing expression of latent HIV-1 with the ultimate goal of eliminating persistent viral reservoirs in certain individuals infected with HIV-1.

Here, we investigated seasonal changes in the in situ metabolic performance of the widely distributed hermatypic coral Pocillopora verrucosa along 12 latitudes featuring a steep temperature gradient between the northern (28.5N, 21-27C) and southern (16.5N, 28-33C) reaches of the Red Sea. Surprisingly, we found little indication for regional adaptation, but strong indications for high phenotypic plasticity: Calcification rates in two seasons (winter, summer) were found to be highest at 28-29C throughout all populations independent of their geographic location.

It covers two-thirds of the Central African Republic and therefore the name derives from the capitol city-Bangui that is also near the center of this feature. From surface magnetic survey data Godivier and Le Donche (1962) were the first to describe this <span class="hlt">anomaly</span>. Subsequently high-altitude world magnetic surveying by the U.S. Naval Oceanographic Office (Project Magnet) recorded a greater than 1000 nT dipolar, peak-to-trough <span class="hlt">anomaly</span> with the major portion being negative (figure 1). Satellite observations (Cosmos 49) were first reported in 1964, these revealed a 40nT <span class="hlt">anomaly</span> at 350 km altitude. Subsequently the higher altitude (417-499km) POGO (Polar Orbiting Geomagnetic Observatory) satellite data recorded peak-to-trough <span class="hlt">anomalies</span> of 20 nT these data were added to Cosmos 49 measurements by Regan et al. (1975) for a regional satellite altitude map. In October 1979, with the launch of Magsat, a satellite designed to measure crustal magnetic <span class="hlt">anomalies</span>, a more uniform satellite altitude magnetic map was obtained. These data, computed at 375 km altitude recorded a -22 nT <span class="hlt">anomaly</span> (figure 2). This elliptically shaped <span class="hlt">anomaly</span> is approximately 760 by 1000 km and is centered at 6%, 18%. The Bangui <span class="hlt">anomaly</span> is composed of three segments; there are two positive <span class="hlt">anomalies</span> lobes north and south of a large central negative field. This displays the classic pattern of a magnetic anomalous body being magnetized by induction in a zero inclination field. This is not surprising since the magnetic equator passes near the center of this body.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=3664986','PMC'); return false;" href="http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=3664986"><span id="translatedtitle">CT colonography for investigation of patients with symptoms <span class="hlt">potentially</span> <span class="hlt">suggestive</span> of colorectal cancer: a review of the UK SIGGAR trials</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pmc">PubMed Central</a></p> <p></p> <p>2013-01-01</p> <p>This paper argues for the use of CT colonography (CTC) to investigate patients with symptoms <span class="hlt">potentially</span> <span class="hlt">suggestive</span> of colorectal cancer. It describes the rationale for the UK Special Interest Group in Gastrointestinal and Abdominal Radiology (SIGGAR) randomised controlled trials that compared CTC with barium enema (BE) or colonoscopy for diagnosis of colorectal cancer or large polyps in symptomatic patients. Diagnostic outcomes from the trials are detailed for both intra- and extracolonic disease, along with psychological reactions of patients to the tests, and cost-effectiveness of the different diagnostic strategies. The author concludes that BE should be replaced by CTC immediately and that CTC is a sensitive, acceptable and equally cost-effective alternative to colonoscopy in patients in whom colonoscopy is contraindicated or undesirable.

The duration of the data set, which is comprised of Aqua-MODIS land surface temperature (LST) night-time snapshot images, is 62 days. In order to quantify variations of LST data obtained from satellite images, the air temperature (AT) data derived from the meteorological station close to the earthquake epicenter has been taken into account. For the models examined here, results indicate the following: (i) ARIMA models, which are the most widely used in the time series community for short-term forecasting, are quickly and easily implemented, and can efficiently act through linear solutions. (ii) A multilayer perceptron (MLP) feed-forward neural network can be a suitable non-parametric method to detect the anomalous changes of a non-linear time series such as variations of LST. (iii) Since SVMs are often used due to their many advantages for classification and regression tasks, it can be shown that, if the difference between the predicted value using the SVM method and the observed value exceeds the pre-defined threshold value, then the observed value could be regarded as an <span class="hlt">anomaly</span>. (iv) ANN and SVM methods could be powerful tools in modeling complex phenomena such as earthquake precursor time series where we may not know what the underlying data generating process is. There is good agreement in the results obtained from the different methods for quantifying <span class="hlt">potential</span> <span class="hlt">anomalies</span> in a given LST time series.

Mutations in this gene disrupt its various isoforms and lead to non-syndromic deafness, blindness and deaf-blindness. However, the known expression of Dfnb31, the mouse ortholog of DFNB31, in vestibular organs and the <span class="hlt">potential</span> vestibular-deficient phenotype observed in one Dfnb31 mutant mouse (Dfnb31(wi/wi)) <span class="hlt">suggest</span> that DFNB31 may also be important for vestibular function. In this study, we find that full-length (FL-) and C-terminal (C-) whirlin isoforms are expressed in the vestibular organs, where their stereociliary localizations are similar to those of developing cochlear inner hair cells. No whirlin is detected in Dfnb31(wi/wi) vestibular organs, while only C-whirlin is expressed in Dfnb31(neo/neo) vestibular organs. Both FL- and C-whirlin isoforms are required for normal vestibular stereociliary growth, although they may play slightly different roles in the central and peripheral zones of the crista ampullaris. Vestibular sensory-evoked <span class="hlt">potentials</span> demonstrate severe to profound vestibular deficits in Dfnb31(neo/neo) and Dfnb31(wi/wi) mice. Swimming and rotarod tests demonstrate that the two Dfnb31 mutants have balance problems, with Dfnb31(wi/wi) mice being more affected than Dfnb31(neo/neo) mice. Because Dfnb31(wi/wi) and Dfnb31(neo/neo) mice faithfully recapitulate hearing and vision symptoms in patients, our findings of vestibular dysfunction in these Dfnb31 mutants raise the question of whether DFNB31-deficient patients may acquire vestibular as well as hearing and vision loss.

Unresolved questions remain, however, regarding the anticipated yield of clinical microarray testing in schizophrenia. Using high-resolution genome-wide microarrays and rigorous methods, we investigated rare CNVs in a prospectively recruited community-based cohort of 459 unrelated adults with schizophrenia and estimated the minimum prevalence of clinically significant CNVs that would be detectable on a clinical microarray. A blinded review by two independent clinical cytogenetic laboratory directors of all large (>500 kb) rare CNVs in cases and well-matched controls showed that those deemed to be clinically significant were highly enriched in schizophrenia (16.4-fold increase, P < 0.0001). In a single community catchment area, the prevalence of individuals with these CNVs was 8.1%. Rare 1.7 Mb CNVs at 2q13 were found to be significantly associated with schizophrenia for the first time, compared with the prevalence in 23 838 population-based controls (42.9-fold increase, P = 0.0002). Additional novel findings that will facilitate the future clinical interpretation of smaller CNVs in schizophrenia include: (i) a greater proportion of individuals with two or more rare exonic CNVs >10 kb in size (1.5-fold increase, P = 0.0109) in schizophrenia; (ii) the systematic discovery of new candidate genes for schizophrenia; and, (iii) functional gene enrichment mapping highlighting a differential impact in schizophrenia of rare exonic deletions involving diverse functions, including neurodevelopmental and synaptic processes (4.7-fold increase, P = 0.0060).

To help gauge the program’s <span class="hlt">potential</span> impact and generalizability, we describe early and current participants. Study Design We examined the cross-sectional association between BPCI participation and providers’ structural and cost characteristics. Methods Using data from October 2013 and June 2014, we quantified changes in BPCI participation. We described structural differences between participating and non-participating hospitals using t-tests and chi-square tests. We used the Cochrane-Armitage test to assess whether participants were more likely be in higher 90-day episode cost quintiles than their peers at baseline (2009–2010). Results Overall (risk-bearing and non-risk-bearing) participation in BPCI increased six-fold from 417 (October 2013) to 2,597 (June 2014), attributable in part to Model 2, the most comprehensive model. Model 2 hospitals increasingly resemble eligible but non-participating hospitals. For the most commonly chosen condition of hip replacement, Model 2 hospitals were not costlier than their peers. Hospitals used to make up 97% of Model 2 participants, but physician practices now comprise half. However, most BPCI participants have not yet begun to bear financial risk. Risk-bearing Model 2 hospitals are a smaller and less representative group, with higher baseline costs for hip replacement than their peers. Conclusions Growing participation in BPCI <span class="hlt">suggests</span> strong interest in bundled payments. The long-term impact of BPCI will depend on CMMI’s ability to persuade interested but non-risk-bearing participants to bear risk.

Modelling current and anticipated changes of the surface energy balance requires an understanding of the spatio-temporal interactions between LST and land cover. This paper investigated the accuracy of MODIS LST V5 1 km level 3 product and its spatio-temporal sensitivity to land cover properties in a Canadian High Arctic permafrost landscape. Land cover ranged from fully vegetated moss/segde grass tundra to sparsely vegetated bare soil and barren areas. Daily mean MODIS LST were compared to in-situ radiometer measurements over wet tundra for three summers and two winters in 2008, 2009, and 2010. MODIS LST showed an accuracy of 1.8°C and a RMSE of 3.8°C in the total observation period including both summer and winter. Agreement was lowest during summer 2009 and freeze-back periods which were associated with prevailing overcast conditions. A multi-year <span class="hlt">anomaly</span> analysis revealed robust spatio-temporal patterns taking into account the found uncertainty and different atmospheric conditions. Summer periods with regional mean LST larger than 5°C showed highest spatial diversity with four distinct <span class="hlt">anomaly</span> classes. Dry ridge areas heated up most whereas wetland areas and dry barren surfaces with high albedo were coolest. Mean inter-annual differences of LST <span class="hlt">anomalies</span> for different land cover classes were less than 1°C. However, spatial pattern showed fewer positive <span class="hlt">anomalies</span> in 2010 <span class="hlt">suggesting</span> differences in surface moisture due to inter­annual differences in the amount of end-of-winter snow. Presented summer LST <span class="hlt">anomalies</span> might serve as a baseline against which to evaluate past and future changes in land surface properties with regard to the surface energy balance. Sub-temporal heterogeneity due to snow or ice on/off as well as the effect of subpixel water bodies has to be taken into account. A multi-sensor approach combining thermal satellite measurements with high-resolution optical and radar imagery therefore promises to be an effective tool for a dynamic, process-based ecosystem monitoring scheme.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2010ATel.2706....1H','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2010ATel.2706....1H"><span id="translatedtitle">Broadband Photometry of the <span class="hlt">Potentially</span> Hazardous Asteroid 1999 MN: <span class="hlt">Suggestive</span> of YORP and/or Tidal Spin-Up?</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Hicks, M.; Mayes, D.; McAuley, A.; Foster, J.</p> <p>2010-06-01</p> <p>1999 MN was discovered by Carl Hergenrother on behalf of the Catalina Sky Survey on June 22 1999 (MPEC 1999-M27) and identified as a <span class="hlt">Potentially</span> Hazardous Asteroid (PHA) by the Minor Planet Center.

Here, the eye of the green crab Carcinus maenas was regarded as a marine sensor model and its surface characterized by means of atomic force microscopy. Engineered surface micro- and nanotopography is a new mechanism found to limit biofouling, promising an effective solution with much reduced environmental impact.

Yet our understanding of the milk microbiome has been limited to cataloguing OTUs and computation of community diversity. To the best of our knowledge, there has been no report on the bacterial interactions within the milk microbiome. To bridge this gap, we reconstructed a milk bacterial community network based on Hunt et al. Our analysis revealed that the milk microbiome network consists of two disconnected sub-networks. One sub-network is a fully connected complete graph consisting of seven genera as nodes and all of its pair-wise interactions among the bacteria are facilitative or cooperative. In contrast, the interactions in the other sub-network of eight nodes are mixed but dominantly cooperative. Somewhat surprisingly, the only 'non-cooperative' nodes in the second sub-network are mutually cooperative Staphylococcus and Corynebacterium that include some opportunistic pathogens. This <span class="hlt">potentially</span> 'evil' alliance between Staphylococcus and Corynebacterium could be inhibited by the remaining nodes that cooperate with one another in the second sub-network. We postulate that the 'confrontation' between the 'evil' alliance and 'benign' alliance and the shifting balance between them may be responsible for dysbiosis of the milk microbiome that permits mastitis.

We investigate range-wide population genetic structure of the California spiny (or red rock) lobster (Panulirus interruptus) and find slight, but significant global population differentiation in mtDNA (ΦST = 0.006, P = 0.001; Dest_Chao = 0.025) and seven nuclear microsatellites (FST = 0.004, P < 0.001; Dest_Chao = 0.03), despite the species’ 240- to 330-day pelagic larval duration. Significant population structure does not correlate with distance between sampling locations, and pairwise FST between adjacent sites often exceeds that among geographically distant locations. This result would typically be interpreted as unexplainable, chaotic genetic patchiness. However, kinship levels differ significantly among sites (pseudo-F16,988 = 1.39, P = 0.001), and ten of 17 sample sites have significantly greater numbers of kin than expected by chance (P < 0.05). Moreover, a higher proportion of kin within sites strongly correlates with greater genetic differentiation among sites (Dest_Chao, R2 = 0.66, P < 0.005). Sites with elevated mean kinship were geographically proximate to regions of high upwelling intensity (R2 = 0.41, P = 0.0009). These results indicate that P. interruptus does not maintain a single homogenous population, despite extreme dispersal <span class="hlt">potential</span>. Instead, these lobsters appear to either have substantial localized recruitment or maintain planktonic larval cohesiveness whereby siblings more likely settle together than disperse across sites. More broadly, our results contribute to a growing number of studies showing that low FST and high family structure across populations can coexist, illuminating the foundations of cryptic genetic patterns and the nature of marine dispersal.

The majority are steel-legged installations (oil and gas jackets) placed in depths ranging from 70 to 200 m. oil fields and structures are soon to be abandoned. Production from the North-east Frigg and Odin fields, was stopped in 1993 and 1994 respectively. From a technical and safety viewpoint, most of the structures are probably removable. Economically, concern has been expressed as to whether it is necessary to remove to shore all the installations. A positive environmental impact may be achieved by using some of the structures as fish aggregating devices. The implications of creating an artificial reef from a steel jacket by toppling in-place are discussed. A typical steel in the Norwegian sector of the North Sea weighs 5,000 - 10,000 tonnes (excluding piles) and has a volume of 100,000 - 150,000 m{sup 3}. It may also be possible to utilize some of the deck modules.

However, deeper phylogenies, such as the datasets that comprise many Tree of Life (ToL) studies, also exhibit gene-tree discordance. This discord may also arise from the stochastic sorting of gene lineages during the speciation process (i.e., reflecting the random coalescence of gene lineages in ancestral populations). It remains unknown whether guidelines regarding methodologies and numbers of loci established by simulation studies at shallow tree depths translate into accurate species relationships for deeper phylogenetic histories. We address this knowledge gap and specifically identify the challenges and limitations of species-tree methods that account for coalescent variance for deeper phylogenies. Using simulated data with characteristics informed by empirical studies, we evaluate both the accuracy of estimated species trees and the characteristics associated with recalcitrant nodes, with a specific focus on whether coalescent variance is generally responsible for the lack of resolution. By determining the proportion of coalescent genealogies that support a particular node, we demonstrate that (1) species-tree methods account for coalescent variance at deep nodes and (2) mutational variance - not gene-tree discord arising from the coalescent - posed the primary challenge for accurate reconstruction across the tree. For example, many nodes were accurately resolved despite predicted discord from the random coalescence of gene lineages and nodes with poor support were distributed across a range of depths (i.e., they were not restricted to a particular recent divergences). Given their broad taxonomic scope and large sampling of taxa, deep level phylogenies pose several <span class="hlt">potential</span> methodological complications including difficulties with MCMC convergence and estimation of requisite population genetic parameters for coalescent-based approaches. Despite these difficulties, the findings generally support the utility of species-tree analyses for the estimation of species relationships throughout the ToL. We discuss strategies for successful application of species-tree approaches to deep phylogenies.

Monitoring of dam performance has become of critical importance, particularly as the structures age and design methods evolve. Conventional monitoring of the hydraulic regime using piezometers and weirs provides sparse sampling, and these methods may not be sufficient to detect the onset of internal erosion. Consequently, a comprehensive investigation tool is needed to complement these methods. The self-<span class="hlt">potential</span> (SP) method has been used to delineate anomalous zones that correspond with areas of preferential seepage flow in embankment dams. Observed responses have been attributed to the electrokinetic phenomenon of streaming <span class="hlt">potential</span>, where electrical current flow is generated by fluid flow through porous media. We have developed a rigorous 3-D finite volume algorithm that calculates the SP field induced by a simulated hydraulic regime, based on the principles of coupled flow. In the current study, we apply the algorithm to investigate the anomalous SP response resulting from seepage through pervious defects in the core of an embankment. While the SP signal due to seepage through the intact embankment is large (in the range of tens of milliVolts), the anomalous responses caused by the presence of pervious defects are close to noise levels for typical measurements made at surface.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://hdl.handle.net/2060/20040034236','NASA-TRS'); return false;" href="http://hdl.handle.net/2060/20040034236"><span id="translatedtitle">Reliability of CHAMP <span class="hlt">Anomaly</span> Continuations</span></a></p> <p><a target="_blank" href="http://ntrs.nasa.gov/search.jsp">NASA Technical Reports Server (NTRS)</a></p> <p>vonFrese, Ralph R.

Firstly, we construct corresponding differential operators for the components of the third-order (disturbing) gravitational tensor in a spherical local north-oriented frame. We show that the differential operators may efficiently be decomposed into an azimuthal and an isotropic part. The differential operators are even more simplified for a certain class of isotropic kernels. Secondly, the differential operators are applied to the well-known integrals of Newton, Abel-Poisson, Pizzetti and Hotine. In this way, 40 new integral formulas are derived. The new integral formulas allow for evaluation of the components of the third-order (disturbing) gravitational tensor from density distribution, disturbing gravitational <span class="hlt">potential</span>, gravity <span class="hlt">anomalies</span> and gravity disturbances. Thirdly, we investigate the behaviour of the corresponding integral kernels in the spatial domain. The new mathematical formulas extend the theoretical apparatus of geodesy, i.e. the well-known Meissl scheme, and reveal important properties of the third-order gravitational tensor.

A.; Nakamura, K.</p> <p>2008-12-01</p> <p>The complex relationships between geological setting and hydrothermal venting have, to date, largely been explored with ship-based surveys that effectively examine regional relationships, or with remotely operated vehicles (ROV) and manned submersibles which allow close examination of individual vent fields. Higher- resolution surveys than are possible with ship-based techniques and broader surveys than are practical with ROVs and manned submersibles are necessary for more thoroughly understanding hydrothermal systems and their impact on ocean ecosystems. Autonomous vehicles (AUVs), such as the WHOI Autonomous Benthic Explorer (ABE) can be programmed to conduct high-resolution surveys that systematically cover a broad area of seafloor. Brothers volcano, a hydrothermally active submarine caldera volcano located on the Kermadec arc northwest of New Zealand, was surveyed in July-August 2007 using ABE. Brothers caldera is ~3 km in diameter with a floor depth of 1850 m and walls that rise 290-530 m above the caldera floor. A dacite cone with a summit depth of ~1200 m sits within the caldera, partially merging with the southern caldera wall. Prior to the survey, active hydrothermal vents were known to be perched along the NW caldera wall and located at three sites on the cone. The enclosed caldera, presence of known vent fields with differing geochemical characteristics, and existence of at least one currently inactive site made Brothers volcano an ideal site for a high-resolution survey to explore in greater detail the mass, thermal and geochemical exchanges of hydrothermal systems. During our expedition, the caldera walls and dacite cone (~7 km2) were completely surveyed by ABE with 50-60 m trackline spacing at an altitude of 50 m above the seafloor. Hydrothermal plumes were mapped with ABE's integrated CTD (conductivity- temperature-depth) and sensors measuring optical backscatter (particle concentrations) and oxidation- reduction <span class="hlt">potential</span> (ORP; indicating the presence of reduced chemical species). This survey resulted in the first high-resolution map of temperature, particle and ORP <span class="hlt">anomalies</span> within a hydrothermally active submarine caldera. New details about the extent and structure of the known active vent fields were revealed, and a new area of active venting was discovered along the west caldera wall. Additionally, relationships between source vents, buoyant plumes, and neutrally buoyant regional plumes mapped using standard surface ship methods can be compared. Simultaneously acquired bathymetry and magnetic <span class="hlt">anomaly</span> data show correlations between the geomorphology of the caldera, magnetic alterations and patterns of past and present hydrothermal venting.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://ntrs.nasa.gov/search.jsp?R=19750039971&hterms=world+map&qs=Ntx%3Dmode%2Bmatchall%26Ntk%3DAll%26N%3D0%26No%3D60%26Ntt%3Dworld%2Bmap','NASA-TRS'); return false;" href="http://ntrs.nasa.gov/search.jsp?R=19750039971&hterms=world+map&qs=Ntx%3Dmode%2Bmatchall%26Ntk%3DAll%26N%3D0%26No%3D60%26Ntt%3Dworld%2Bmap"><span id="translatedtitle">A global magnetic <span class="hlt">anomaly</span> map</span></a></p> <p><a target="_blank" href="http://ntrs.nasa.gov/search.jsp">NASA Technical Reports Server (NTRS)</a></p> <p>Regan, R.

In the context of Accident Precursor Analysis (APA), under which this method has been developed, these vulnerabilities, designated as <span class="hlt">anomaly</span> vulnerabilities, are conditions that produce high risk in the presence of anomalous system behavior. The method defines a parameter-specific Parameter Vulnerability Importance measure (PVI), which identifies <span class="hlt">anomaly</span> risk-model parameter values that indicate the <span class="hlt">potential</span> presence of <span class="hlt">anomaly</span> vulnerabilities, and allows them to be prioritized for further investigation.

Results from the LSND and MiniBooNE short-baseline νe /νe appearance experiments show <span class="hlt">anomalies</span> which cannot be described by oscillations between the three standard model neutrinos (the ``LSND <span class="hlt">anomaly</span>''). In addition, a re-analysis of the anti-neutrino flux produced by nuclear power reactors has led to an apparent deficit in νe event rates in a number of reactor experiments (the ``reactor <span class="hlt">anomaly</span>''). Similarly, calibration runs using 51Cr and 37Ar radioactive sources in the Gallium solar neutrino experiments GALLEX and SAGE have shown an unexplained deficit in the electron neutrino event rate over very short distances (the ``Gallium <span class="hlt">anomaly</span>''). The puzzling results from these experiments, which together may <span class="hlt">suggest</span> the existence of physics beyond the Standard Model and hint at exciting new physics, including the possibility of additional low-mass sterile neutrino states, have raised the interest in the community for new experimental efforts that could eventually solve this puzzle. Definitive evidence for sterile neutrinos would be a revolutionary discovery, with implications for particle physics as well as cosmology. Proposals to address these signals by employing accelerator, reactor and radioactive source experiments are in the planning stages or underway worldwide.

Some methods in environmental geochemistry incorporate the premise that <span class="hlt">anomalies</span> (natural or anthropogenic) and background data are characterized by their own probabilistic distributions. One of these methods uses exploratory data analysis (EDA) on regional geochemical data sets coupled with a geographic information system (GIS) to spatially understand the processes that influence the geochemical landscape in a technique that can be called a spatial data analysis (SDA). This EDA-SDA methodology was used to establish the regional background range from the area of Catorce-Matehuala in north-central Mexico. Probability plots of the data, particularly for those areas affected by human activities, show that the regional geochemical background population is composed of smaller subpopulations associated with factors such as soil type and parent material.

TEC is highly variable due to the influences of solar flux, geomagnetic activity, and seasonal variation and these influences are removed by the use of model.

A minor population of SiC (known as Grains X, ca. 1%) are distinct in having decay products of short lived isotopes 26Al (now 26Mg), 44Ti (now 44Ca), and 49V (now 49Ti), as well as 28Si excesses which are characteristic of supernova nucleosynthesis.

Cholate-degrading bacteria could be readily isolated from freshwater environments. All isolated strains transiently released steroid degradation intermediates into culture supernatants before their further degradation. Cholate degradation could be initiated via two different reaction sequences. Most strains degraded cholate via a reaction sequence known from the model organism Pseudomonas sp. strain Chol1 releasing intermediates with a 3-keto-?(1,4) -diene structure of the steroid skeleton. The actinobacterium Dietzia sp. strain Chol2 degraded cholate via a different and yet unexplored reaction sequence releasing intermediates with a 3-keto-?(4,6) -diene-7-deoxy structure of the steroid skeleton such as 3,12-dioxo-4,6-choldienoic acid (DOCDA). Using DOCDA as substrate, two Alphaproteobacteria, strains Chol10-11, were isolated that produced the same cholate degradation intermediates as strain Chol2. With DOCDA as substrate for Pseudomonas sp. strain Chol1 only the side chain was degraded while the ring system was transformed into novel steroid compounds accumulating as dead-end metabolites. These metabolites could be degraded by the DOCDA-producing strains Chol10-11.

The FGF2 neutralizing effect of this antibody was certified by in vitro assays, which allowed the further track of its possible in vivo application. 3F12E7 mAb could be retained in B16-F10 tumors, as shown by antibody low-pH elution and nuclear medicine studies, and also led to reduction in number and size of metastatic foci in lungs, when treatment starts one day after intravenous injection of B16-F10 cells.

Diseased fibroblasts (dFib) isolated from the fibrotic conjunctivae of ocular mucous membrane pemphigoid (Oc-MMP) patients were used as a pro-scarring positive control against which hLF were compared using surrogate scarring parameters: matrix metalloproteinase (MMP) activity, de novo collagen synthesis, ?-smooth muscle actin (?-SMA) expression, and transforming growth factor-?

MMP-2 and -9 activity, de novo collagen synthesis, and ?-SMA expression were all increased in dFib cf. normal hLF RAFT TEs, although TGF-?1 secretion did not differ between normal hLF and dFib RAFT TEs. Normal hLF do not progress toward a scarring-like phenotype during culture in RAFT TEs and, therefore, may be safe to include in therapeutic RAFT TE, where they can support hLE, although in vivo work is required to confirm this. dFib RAFT TEs (used in this study as a positive control) may be useful toward the development of an ex vivo disease model of Oc-MMP.

The aim of this work was to assess the scarring phenotype of hLF in RAFT TEs in hLE+ and hLE? RAFT TEs and in nonairlifted and airlifted RAFT TEs. Diseased fibroblasts (dFib) isolated from the fibrotic conjunctivae of ocular mucous membrane pemphigoid (Oc-MMP) patients were used as a pro-scarring positive control against which hLF were compared using surrogate scarring parameters: matrix metalloproteinase (MMP) activity, de novo collagen synthesis, ?-smooth muscle actin (?-SMA) expression, and transforming growth factor-? (TGF-?) secretion. Normal hLF and dFib maintained different phenotypes in RAFT TE. MMP-2 and -9 activity, de novo collagen synthesis, and ?-SMA expression were all increased in dFib cf. normal hLF RAFT TEs, although TGF-?1 secretion did not differ between normal hLF and dFib RAFT TEs. Normal hLF do not progress toward a scarring-like phenotype during culture in RAFT TEs and, therefore, may be safe to include in therapeutic RAFT TE, where they can support hLE, although in vivo work is required to confirm this. dFib RAFT TEs (used in this study as a positive control) may be useful toward the development of an ex vivo disease model of Oc-MMP.

Here we have simulated the oral uptake of 50 nm carboxylated polystyrene nanoparticles with a microscale, body-on-a-chip system (also referred to as multi-tissue microphysiological system or micro Cell Culture Analog). Using this system, we combined in vitro models of the human intestinal epithelium, represented by a co-culture of enterocytes (Caco-2) and mucin-producing (HT29-MTX) cells, and the liver, represented by HepG2/C3A cells, within one microfluidic device. The device also contained chambers that together represented all other organs of the human body. Measuring the transport of 50 nm carboxylated polystyrene nanoparticles across the Caco-2/HT29-MTX co-culture, we have found that this multi-cell layer presents an effective barrier to 90.5 ± 2.9% of the nanoparticles. Further, our simulation <span class="hlt">suggests</span> that a larger fraction of the 9.5 ± 2.9% of nanoparticles that travelled across the Caco-2/HT29-MTX cell layer were not large nanoparticle aggregates, but primarily single nanoparticles and small aggregates. After crossing the GI tract epithelium, nanoparticles that were administered in high doses estimated in terms of possible daily human consumption (240 and 480 × 1011 nanoparticles/mL) induced the release of aspartate aminotransferase (AST), an intracellular enzyme of the liver that indicates liver cell injury. Using the GI ‘tract – liver – other tissue’ system allowed us to observe compounding effects and detect liver tissue injury at lower nanoparticle concentrations than expected from experiments with liver tissue only. Our results indicate that body-on-a-chip devices are highly relevant in vitro models for evaluating nanoparticle interactions with human tissues.

FTY720 treatment in pregnant inbred LM/Bc mice results in approximately 60% of embryos having a neural tube defect (NTD). Sphingosine kinases (Sphk1, Sphk2) phosphorylate FTY720 in vivo to form the bioactive metabolite FTY720-1-phosphate (FTY720-P). Cytoplasmic FTY720-P is an agonist for 4 of the 5 sphingosine-1-phosphate (S1P) receptors (S1P1, 3-5) and can also act as a functional antagonist of S1P1, whereas FTY720-P generated in the nucleus inhibits histone deacetylases (HDACs), leading to increased histone acetylation. This study demonstrates that treatment of LM/Bc mouse embryonic fibroblasts (MEFs) with FTY720 results in a significant accumulation of FTY720-P in both the cytoplasmic and nuclear compartments. Elevated nuclear FTY720-P is associated with decreased HDAC activity and increased histone acetylation at H3K18 and H3K23 in LM/Bc MEFs. Treatment of LM/Bc MEFs with FTY720 and a selective Sphk2 inhibitor, ABC294640, significantly reduces the amount of FTY720-P that accumulates in the nucleus. The data provide insight into the relative amounts of FTY720-P generated in the nuclear versus cytoplasmic subcellular compartments after FTY720 treatment and the specific Sphk isoforms involved. The results of this study <span class="hlt">suggest</span> that FTY720-induced NTDs may involve multiple mechanisms, including: (1) sustained and/or altered S1P receptor activation and signaling by FTY720-P produced in the cytoplasm and (2) HDAC inhibition and histone hyperacetylation by FTY720-P generated in the nucleus that could lead to epigenetic changes in gene regulation.

Perhaps the most disturbing is the fact that when a spacecraft on a flyby trajectory approaches the Earth within 2000 km or less, it experiences a gain in total orbital energy per unit mass (Anderson et al., Phys. Rev. Lett. 100, 091102). This amounts to a net velocity increase of 13.5 mm/s for the NEAR spacecraft at a closest approach of 539 km, 3.9 mm/s for the Galileo spacecraft at 960 km, and 1.8 mm/s for the Rosetta spacecraft at 1956 km. Next, I <span class="hlt">suggest</span> the change in the astronomical unit AU is definitely a concern. It is increasing by about 15 cm/yr (Krasinsky and Brumberg, Celes. Mech. & Dynam. Astron. 90, 267). The other two <span class="hlt">anomalies</span> are perhaps less disturbing because of known sources of nongravitational acceleration. The first is an apparent slowing of the two Pioneer spacecraft as they exit the solar system in opposite directions (Anderson et al., Phys. Rev. D 65, 082004). Some, including me, are convinced this effect is of concern, but many are convinced it is produced by a nearly identical thermal emission from both spacecraft, in a direction away from the Sun, thereby producing acceleration toward the Sun. The fourth <span class="hlt">anomaly</span> is a measured increase in the eccentricity of the Moon's orbit. Here again, an increase is expected from tidal friction in both the Earth and Moon. However, there is a reported increase that is about three times larger than expected (J. G. Williams, DDA/AAS Brouwer Award Lecture, Halifax, Nova Scotia 2006). We suspect that all four <span class="hlt">anomalies</span> have mundane explanations. However, the possibility that they will be explained by a new theory of gravitation is not ruled out, perhaps analogous to Einstein's 1916 explanation of the excess precession of Mercury's perihelion.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.ncbi.nlm.nih.gov/pubmed/19820092','PUBMED'); return false;" href="http://www.ncbi.nlm.nih.gov/pubmed/19820092"><span id="translatedtitle">Crystal structure of Adenylylsulfate reductase from Desulfovibrio gigas <span class="hlt">suggests</span> a <span class="hlt">potential</span> self-regulation mechanism involving the C terminus of the beta-subunit.</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Chiang, Yuan-Lan; Hsieh, Yin-Cheng; Fang, Jou-Yin; Liu, En-Hong; Huang, Yen-Chieh; Chuankhayan, Phimonphan; Jeyakanthan, Jeyaraman; Liu, Ming-Yih; Chan, Sunney I; Chen, Chun-Jung</p> <p>2009-12-01</p> <p>Adenylylsulfate reductase (adenosine 5'-phosphosulfate [APS] reductase [APSR]) plays a key role in catalyzing APS to sulfite in dissimilatory sulfate reduction. Here, we report the crystal structure of APSR from Desulfovibrio gigas at 3.1-A resolution. Different from the alpha(2)beta(2)-heterotetramer of the Archaeoglobus fulgidus, the overall structure of APSR from D. gigas comprises six alphabeta-heterodimers that form a hexameric structure. The flavin adenine dinucleotide is noncovalently attached to the alpha-subunit, and two [4Fe-4S] clusters are enveloped by cluster-binding motifs. The substrate-binding channel in D. gigas is wider than that in A. fulgidus because of shifts in the loop (amino acid 326 to 332) and the alpha-helix (amino acid 289 to 299) in the alpha-subunit. The positively charged residue Arg160 in the structure of D. gigas likely replaces the role of Arg83 in that of A. fulgidus for the recognition of substrates. The C-terminal segment of the beta-subunit wraps around the alpha-subunit to form a functional unit, with the C-terminal loop inserted into the active-site channel of the alpha-subunit from another alphabeta-heterodimer. Electrostatic interactions between the substrate-binding residue Arg282 in the alpha-subunit and Asp159 in the C terminus of the beta-subunit affect the binding of the substrate. Alignment of APSR sequences from D. gigas and A. fulgidus shows the largest differences toward the C termini of the beta-subunits, and structural comparison reveals notable differences at the C termini, activity sites, and other regions. The disulfide comprising Cys156 to Cys162 stabilizes the C-terminal loop of the beta-subunit and is crucial for oligomerization. Dynamic light scattering and ultracentrifugation measurements reveal multiple forms of APSR upon the addition of AMP, indicating that AMP binding dissociates the inactive hexamer into functional dimers, presumably by switching the C terminus of the beta-subunit away from the active site. The crystal structure of APSR, together with its oligomerization properties, <span class="hlt">suggests</span> that APSR from sulfate-reducing bacteria might self-regulate its activity through the C terminus of the beta-subunit.

We first summarize the characteristics of several solar wind plasma composition signatures (O(+7)/O(+6), Mg/O, Ne/O, Fe charge states, He/p) observed by the ACE and WIND spacecraft within the ICMEs during 1996 - 2002 identsed by Cane and Richardson. We then develop a set of simple criteria that may be used to identify such compositional <span class="hlt">anomalies</span>, and hence <span class="hlt">potential</span> ICMEs. To distinguish these <span class="hlt">anomalies</span> from the normal variations seen in ambient solar wind composition, which depend on the wind speed, we compare observed compositional signatures with those 'expected' in ambient solar wind with the same solar wind speed. This method identifies <span class="hlt">anomalies</span> more effectively than the use of fixed thresholds. The occurrence rates of individual composition <span class="hlt">anomalies</span> within ICMEs range from approx. 70% for enhanced iron and oxygen charge states to approx. 30% for enhanced He/p (> 0.06) and Ne/O, and are generally higher in magnetic clouds than other ICMEs. Intervals of multiple <span class="hlt">anomalies</span> are usually associated with ICMEs, and provide a basis for the identification of the majority of ICMEs. We estimate that Cane and Richardson, who did not refer to composition data, probably identitied approx. 90% of the ICMEs present. However, around 10% of their ICMEs have weak compositional <span class="hlt">anomalies</span>, <span class="hlt">suggesting</span> that the presence of such signatures does not provide a necessary requirement for an ICME. We note a remarkably similar correlation between the Mg/O and O(7)/O(6) ratios in hourly-averaged data both within ICMEs and the ambient solar wind. This 'universal' relationship <span class="hlt">suggests</span> that a similar process (such as minor ion heating by waves inside coronal magnetic field loops) produces the first-ionization <span class="hlt">potential</span> bias and ion freezing-in temperatures in the source regions of both ICMEs and the ambient solar wind.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=3720026','PMC'); return false;" href="http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=3720026"><span id="translatedtitle">Response of African humid tropical forests to recent rainfall <span class="hlt">anomalies</span></span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pmc">PubMed Central</a></p> <p>Asefi-Najafabady, Salvi; Saatchi, Sassan</p> <p>2013-01-01</p> <p>During the last decade, strong negative rainfall <span class="hlt">anomalies</span> resulting from increased sea surface temperature in the tropical Atlantic have caused extensive droughts in rainforests of western Amazonia, exerting persistent effects on the forest canopy.

In this paper, however, we show by means of a semiclassical analysis that the trace <span class="hlt">anomaly</span> does not affect the cosmological constant. We construct the effective action of the conformal <span class="hlt">anomaly</span> for flat Friedmann-Lemaitre-Robertson-Walker spacetimes consisting of local quadratic geometric curvature invariants. Counterterms are thus expected to influence the numerical value of the coefficients in the trace <span class="hlt">anomaly</span> and we must therefore allow these parameters to vary. We calculate the evolution of the Hubble parameter in quasi-de Sitter spacetime, where we restrict our Hubble parameter to vary slowly in time, and in Friedmann-Lemaitre-Robertson-Walker spacetimes. We show dynamically that a universe consisting of matter with a constant equation of state, a cosmological constant, and the quantum trace <span class="hlt">anomaly</span> evolves either to the classical de Sitter attractor or to a quantum trace <span class="hlt">anomaly</span> driven one. When considering the trace <span class="hlt">anomaly</span> truncated to quasi-de Sitter spacetime, we find a region in parameter space where the quantum attractor destabilizes. When considering the exact expression of the trace <span class="hlt">anomaly</span>, a stability analysis shows that whenever the trace <span class="hlt">anomaly</span> driven attractor is stable, the classical de Sitter attractor is unstable, and vice versa. Semiclassically, the trace <span class="hlt">anomaly</span> does not affect the classical late time de Sitter attractor, and hence it does not solve the cosmological constant problem.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://pubs.er.usgs.gov/publication/70122682','USGSPUBS'); return false;" href="http://pubs.er.usgs.gov/publication/70122682"><span id="translatedtitle">Antler <span class="hlt">anomalies</span> in tule elk</span></a></p> <p><a target="_blank" href="http://pubs.er.usgs.gov/pubs/index.jsp?view=adv">USGS Publications Warehouse</a></p> <p>Gogan, Peter J.P.; Jessup, David A.; Barrett, Reginald H.</p> <p>1988-01-01</p> <p>Antler <span class="hlt">anomalies</span> were evident in tule elk (Cervus elaphus nannodes) within 1 yr of reintroduction to Point Reyes, California (USA).

Most of them occur sporadically, i.e. there is no familial history of lesions, yet in a few cases clear inheritance is observed. These inherited forms are often characterized by multifocal lesions that are mainly small in size and increase in number with patients age. On the basis of these inherited forms, molecular genetic studies have unraveled a number of inherited mutations giving direct insight into the pathophysiological cause and the molecular pathways that are implicated. Genetic defects have been identified for hereditary haemorrhagic telangiectasia (HHT), inherited cutaneomucosal venous malformation (VMCM), glomuvenous malformation (GVM), capillary malformation - arteriovenous malformation (CM-AVM), cerebral cavernous malformation (CCM) and some isolated and syndromic forms of primary lymphedema. We focus on these disorders, the implicated mutated genes and the underlying pathogenic mechanisms. We also call attention to the concept of Knudsons double-hit mechanism to explain incomplete penetrance and the large clinical variation in expressivity of inherited vascular <span class="hlt">anomalies</span>. This variability renders the making of correct diagnosis of the rare inherited forms difficult. Yet, the identification of the pathophysiological causes and pathways involved in them has had an unprecedented impact on our thinking of their etiopathogenesis, and has opened the doors towards a more refined classification of vascular <span class="hlt">anomalies</span>. It has also made it possible to develop animal models that can be tested for specific molecular therapies, aimed at alleviating the dysfunctions caused by the aberrant genes and proteins.

Distillation enriches the heavy isotopes in the residue and the light isotopes in the vapor. However, current models appear to be inadequate to describe the detailed mass dependence, in particular for large fractionations. Coarse- and fine-grained inclusions from the Allende meteorite exhibit correlated isotope effects in Mg both as mass-dependent fractionation and residual <span class="hlt">anomalies</span>. This isotope pattern can be duplicated by high temperature distillation in the laboratory. A ubiquitous property of meteoritic inclusions for Mg as well as for most of the other elements, where measurements exist, is mass-dependent fractionation. In contrast, terrestrial materials such as microtektites, tektite buttons as well as lunar orange and green glass spheres have normal Mg isotopic composition. A subset of interplanetary dust particles labelled as chondritic aggregates exhibit excesses in {sup 26}Mg and deuterium <span class="hlt">anomalies</span>. Sputtering is expected to be a dominant mechanism in the destruction of grains within interstellar dust clouds. An active proto-sun as well as the present solar-wind and solar-flare flux are of sufficient intensity to sputter significant amounts of material. Laboratory experiments in Mg show widespread isotope effects including residual {sup 26}Mg excesses and mass dependent fractionation. It is possible that the {sup 26}Mg excesses in interplanetary dust is related to sputtering by energetic solar-wind particles.

When a physical shockwave is formed, it moves through the flow with a certain speed, having some finite width determined by physical dissipation until it encounters some event in its path. For numerical shockwaves, however, a numerical width is enforced, often much greater than the physical width. With this numerical width comes the formation of intermediate states having no direct physical interpretation. Even as the mesh is refined, these intermediate states do not go away; they simply occupy less space. The existence of intermediate states does raise some doubt, however, about how closely a captured shockwave may emulate an ideal discontinuous shockwave, or a real physical one. There are in fact several types of error associated with intermediate shock states such as errors in shock position, spurious waves, or unstable shock behavior. These errors can be classified as numerical shockwave <span class="hlt">anomalies</span>; they are numerical artifacts formed due to the presence of captured shockwaves within the flow solution. Each numerical shockwave <span class="hlt">anomaly</span> is directly related to the nonlinearity of the jump conditions and to a resulting ambiguity in sub-cell shock position in a stationary shock. Two new flux functions are developed that do not have this ambiguity. On all of the shock <span class="hlt">anomalies</span> in one-dimension, both flux functions show improvement on existing methods without smearing or diffusing the shock. They are also shown to perform adequately within a second-order framework and on two-dimensional problems, important for the practicality of the method. While they are still susceptible to many of the problems that occur in Roe's Riemann solver and several other known issues, these methods serve to validate the philosophy and approach taken in this thesis: by enforcing a linear shock structure and unambiguous sub-cell shock position, numerical shockwave <span class="hlt">anomalies</span> are dramatically reduced.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/1992Sci...255..690L','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/1992Sci...255..690L"><span id="translatedtitle">When do <span class="hlt">anomalies</span> begin?</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Lightman, Alan; Gingerich, Owen</p> <p>1992-02-01</p> <p>The present historical and methodological consideration of scientific <span class="hlt">anomalies</span> notes that some of these are recognized as such, after long neglect, only after the emergence of compelling explanations for their presence in the given theory in view of an alternative conceptual framework.

Kuhn promoted a monistic phase-model of scientific advance, according to which a paradigm driven `normal science' gives rise to its own <span class="hlt">anomalies</span>, which then lead to a crisis and eventually a scientific revolution. Feyerabend stressed the importance of pluralism for scientific progress. He rejected Kuhn's model arguing that it fails to recognize the role that alternative theories can play in identifying exactly which phenomena are anomalous in the first place.

These include uses such as identifying possible heart conditions from an Electrocardiography (ECG) signals or predicting earthquakes via seismographic data. Over the many choices of <span class="hlt">anomaly</span> detection algorithms, it is important to compare possible methods. In this paper, we examine and compare two approaches to <span class="hlt">anomaly</span> detection and see how data fusion methods may improve performance. The first approach involves using an artificial neural network (ANN) to detect <span class="hlt">anomalies</span> in a wavelet de-noised signal. The other method uses a perspective neural network (PNN) to analyze an arbitrary number of "perspectives" or transformations of the observed signal for <span class="hlt">anomalies</span>. Possible perspectives may include wavelet de-noising, Fourier transform, peak-filtering, etc.. In order to evaluate these techniques via signal fusion metrics, we must apply signal preprocessing techniques such as de-noising methods to the original signal and then use a neural network to find <span class="hlt">anomalies</span> in the generated signal. From this secondary result it is possible to use data fusion techniques that can be evaluated via existing data fusion metrics for single and multiple perspectives.

Turtles are excellent models for the study of developmental instability because <span class="hlt">anomalies</span> are easily detected in the form of malformations, additions, or reductions in the number of scutes or scales. Methodology/Principal Findings In this study, we integrated field observations, manipulative experiments, and climatic and genetic approaches to investigate the origin of carapace scute <span class="hlt">anomalies</span> across Iberian populations of the European pond turtle, Emys orbicularis. The proportion of anomalous individuals varied from 3% to 69% in local populations, with increasing frequency of <span class="hlt">anomalies</span> in northern regions. We found no significant effect of climatic and soil moisture, or climatic temperature on the occurrence of <span class="hlt">anomalies</span>. However, lower genetic diversity and inbreeding were good predictors of the prevalence of scute <span class="hlt">anomalies</span> among populations. Both decreasing genetic diversity and increasing proportion of anomalous individuals in northern parts of the Iberian distribution may be linked to recolonization events from the Southern Pleistocene refugium. Conclusions/Significance Overall, our results <span class="hlt">suggest</span> that developmental instability in turtle carapace formation might be caused, at least in part, by genetic factors, although the influence of environmental factors affecting the developmental stability of turtle carapace cannot be ruled out. Further studies of the effects of environmental factors, pollutants and heritability of <span class="hlt">anomalies</span> would be useful to better understand the complex origin of <span class="hlt">anomalies</span> in natural populations.

Geological studies and hydro-uranium <span class="hlt">anomaly</span> <span class="hlt">suggest</span> the presence of Uranium deposit around Raghunathpur village which lies about 8 km north of SPSZ. However, detailed geophysical investigations have not been carried out in this region for investigation of uranium mineralization. Since surface signature of uranium mineralization is not depicted near the location, a deeper subsurface source is expected for hydro uranium <span class="hlt">anomaly</span>. To delineate the subsurface structure and to investigate the origin of hydro-uranium <span class="hlt">anomaly</span> present in the area, Vertical Electrical Sounding (VES) using Schlumberger array and Gradient Resistivity Profiling (GRP) were performed at different locations along a profile perpendicular to the South Purulia Shear Zone. Apparent resistivity computed from the measured sounding data at various locations shows a continuously increasing trend. As a result, conventional apparent resistivity data is not able to detect the possible source of hydro uranium <span class="hlt">anomaly</span>. An innovative approach is applied which depicts the apparent conductivity in the subsurface revealed a possible connection from SPSZ to Raghunathpur. On the other hand resistivity profiling data <span class="hlt">suggests</span> a low resistive zone which is also characterized by low Self-<span class="hlt">Potential</span> (SP) <span class="hlt">anomaly</span> zone. Since SPSZ is characterized by the source of uranium mineralization; hydro-uranium <span class="hlt">anomaly</span> at Raghunathpur is connected with the SPSZ. The conducting zone has been delineated from SPSZ to Raghunathpur at deeper depths which could be uranium bearing. Since the location is also characterized by a low gravity and high magnetic <span class="hlt">anomaly</span> zone, this conducting zone is likely to be mineralized zone.

Normal maturation and selective regression of these structures form the adult vasculature. Abnormal location or development of the aortic arches may result in pressure on adjacent organs. Vascular ring <span class="hlt">anomalies</span> must be considered with any patient with a history of regurgitating food shortly after eating. Physical examination, test feedings, survey and contrast radiographs may give an accurate impression of the problem but a final diagnosis can only be made following surgical exploration. In the case presented, the dog had all the clinical and diagnostic signs <span class="hlt">suggestive</span> of a vascular ring <span class="hlt">anomaly</span>. Thoracotomy and elimination of the vascular constriction around the esophagus was both diagnostic and therapeutic for the condition. It is important that owners be made aware that surgical correction of the stenosis does not guarantee a successful conclusion to the case. If the dilation of the esophagus cranial to the stenosis is severe, accumulation of food with subsequent regurgitation may persist. A dilation of the esophagus caudal to the stenosis is present in a large percentage of cases and this also may result in an unrelenting problem. Unfortunately, the probability of these complications cannot be accurately evaluated prior to treatment. The hereditary <span class="hlt">potential</span> for this defect must also be considered. Congenital vascular <span class="hlt">anomalies</span> such as patent ductus arteriosus would seem to have a hereditary basis. Therefore, it is probably correct to advise against breeding affected animals. Further, the inbreeding of nonaffected animals which come from litters containing affected animals should be avoided.

The system of equations describing the model is nonlinear and quasi -geostrophic (linear balance). Static stability is variable in the model. A moisture budget is calculated in the lower layer only. Convective adjustment is used to avoid supercritical temperature lapse rates. The mechanical forcing of topography is introduced as a vertical velocity at the lower boundary. Solar forcing is specified assuming a daily mean zenith angle. The differential diabatic heating between land and sea is parameterized. On land- and sea-ice surfaces, a steady state thermal energy equation is solved to calculate the surface temperature. On the oceans, the sea surface temperature is specified as the climatological average for January, February and March circulations. Experiments are designed to study the response of the atmosphere to thermal <span class="hlt">anomalies</span> at the lower boundary or in the midtroposphere. The "memory" in the atmosphere of such <span class="hlt">anomalies</span>, after they have decayed, is also studied. Three patterns of sea surface temperature <span class="hlt">anomalies</span> are tested. The first pattern represents a cold <span class="hlt">anomaly</span> in the North Pacific, the second a warm <span class="hlt">anomaly</span> in the equatorial Pacific and the third pattern contains both of the two <span class="hlt">anomaly</span> patterns acting together. The results <span class="hlt">suggest</span> that the coupled pattern is the only one that produces the type of geopotential <span class="hlt">anomalies</span> associated with the negative phase of the Southern Oscillation. In contrast to the results of linear models, warm sea surface temperature <span class="hlt">anomalies</span> in the equatorial Pacific cannot produce such geopotential response on their own. The mid-tropospheric <span class="hlt">anomaly</span> is introduced as an easterly propagating wave over the equatorial Pacific and over the Gulf of Bengal. The amplitude and memory of the response is larger than for the sea surface temperature case. The mid-tropospheric thermal <span class="hlt">anomalies</span> show continuous large areas of long memory in the subtropical and middle latitude regions of the Northern Hemisphere.</p> </li> </ol> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_8");'>8</a></li> <li><a href="#" onclick='return showDiv("page_9");'>9</a></li> <li class="active"><span>10</span></li> <li><a href="#" onclick='return showDiv("page_11");'>11</a></li> <li><a href="#" onclick='return showDiv("page_12");'>12</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div><!-- col-sm-12 --> </div><!-- row --> </div><!-- page_10 --> <div id="page_11" class="hiddenDiv"> <div class="row"> <div class="col-sm-12"> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_9");'>9</a></li> <li><a href="#" onclick='return showDiv("page_10");'>10</a></li> <li class="active"><span>11</span></li> <li><a href="#" onclick='return showDiv("page_12");'>12</a></li> <li><a href="#" onclick='return showDiv("page_13");'>13</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div> </div> <div class="row"> <div class="col-sm-12"> <ol class="result-class" start="201"> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2014PhRvX...4c1035P','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2014PhRvX...4c1035P"><span id="translatedtitle">Probing the Chiral <span class="hlt">Anomaly</span> with Nonlocal Transport in Three-Dimensional Topological Semimetals</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Parameswaran, S. A.; Grover, T.; Abanin, D. A.; Pesin, D. A.; Vishwanath, A.</p> <p>2014-07-01</p> <p>Weyl semimetals are three-dimensional crystalline systems where pairs of bands touch at points in momentum space, termed Weyl nodes, that are characterized by a definite topological charge: the chirality. Consequently, they exhibit the Adler-Bell-Jackiw <span class="hlt">anomaly</span>, which in this condensed-matter realization implies that the application of parallel electric (E) and magnetic (B) fields pumps electrons between nodes of opposite chirality at a rate proportional to E .B. We argue that this pumping is measurable via nonlocal transport experiments, in the limit of weak internode scattering. Specifically, we show that as a consequence of the <span class="hlt">anomaly</span>, applying a local magnetic field parallel to an injected current induces a valley imbalance that diffuses over long distances. A probe magnetic field can then convert this imbalance into a measurable voltage drop far from source and drain. Such nonlocal transport vanishes when the injected current and magnetic field are orthogonal and therefore serves as a test of the chiral <span class="hlt">anomaly</span>. We further demonstrate that a similar effect should also characterize Dirac semimetals—recently reported to have been observed in experiments—where the coexistence of a pair of Weyl nodes at a single point in the Brillouin zone is protected by a crystal symmetry. Since the nodes are analogous to valley degrees of freedom in semiconductors, the existence of the <span class="hlt">anomaly</span> <span class="hlt">suggests</span> that valley currents in three-dimensional topological semimetals can be controlled using electric fields, which has <span class="hlt">potential</span> practical "valleytronic" applications.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/biblio/22375825','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/biblio/22375825"><span id="translatedtitle">Relic vector field and CMB large scale <span class="hlt">anomalies</span></span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Chen, Xingang; Wang, Yi E-mail: yw366@cam.ac.uk</p> <p>2014-10-01</p> <p>We study the most general effects of relic vector fields on the inflationary background and density perturbations.

These networks can be extremely large and so detecting any changes in their structure can be computationally challenging; hence, computationally fast, parallelisable methods for monitoring the network are paramount. For this reason the methods presented here use independent node and edge based models to detect locally anomalous substructures within communication networks. As a first stage, the aim is to detect changes in the data streams arising from node or edge communications. Throughout the thesis simple, conjugate Bayesian models for counting processes are used to model these data streams. A second stage of analysis can then be performed on a much reduced subset of the network comprising nodes and edges which have been identified as <span class="hlt">potentially</span> anomalous in the first stage. The first method assumes communications in a network arise from an inhomogeneous Poisson process with piecewise constant intensity. <span class="hlt">Anomaly</span> detection is then treated as a changepoint problem on the intensities. The changepoint model is extended to incorporate seasonal behavior inherent in communication networks. This seasonal behavior is also viewed as a changepoint problem acting on a piecewise constant Poisson process. In a static time frame, inference is made on this extended model via a Gibbs sampling strategy. In a sequential time frame, where the data arrive as a stream, a novel, fast Sequential Monte Carlo (SMC) algorithm is introduced to sample from the sequence of posterior distributions of the change points over time. A second method is considered for monitoring communications in a large scale computer network. The usage patterns in these types of networks are very bursty in nature and don’t fit a Poisson process model. For tractable inference, discrete time models are considered, where the data are aggregated into discrete time periods and probability models are fitted to the communication counts. In a sequential analysis, anomalous behavior is then identified from outlying behavior with respect to the fitted predictive probability models. Seasonality is again incorporated into the model and is treated as a changepoint model on the transition probabilities of a discrete time Markov process. Second stage analytics are then developed which combine anomalous edges to identify anomalous substructures in the network.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://pubs.er.usgs.gov/publication/70001226','USGSPUBS'); return false;" href="http://pubs.er.usgs.gov/publication/70001226"><span id="translatedtitle">A major geothermal <span class="hlt">anomaly</span> in the Gulf of California</span></a></p> <p><a target="_blank" href="http://pubs.er.usgs.gov/pubs/index.jsp?view=adv">USGS Publications Warehouse</a></p> <p>Lawver, L.A.; Williams, D.L.; Von Herzen, R.

L.</p> <p>2012-12-01</p> <p>Hot Flow <span class="hlt">Anomalies</span> (HFAs) were first discovered in 1980s. These are active processes of hot plasma bulks formation that usually occur at planetary bow shocks. Though HFA were studied for long time it is still not clear if they are reforming structures and what defines particular internal structure of HFA. Our study is based on the Interball Tail Probe data. We used 10-sec measurements of complex plasma analyzer SCA-1 and 1-second magnetic field measurements, and ELECTRON spectrometer 2-dimensional measurements with 3,75-sec temporal resolution. Five <span class="hlt">anomalies</span> that were observed on the basis of well resolved structure for which we obtained displacement velocity along bow shock, flow velocities within HFA, and estimated the size. We checked if main criteria of HFA formation were fulfilled for each case. The following criteria were satisfied: motional electric field direction was directed toward current sheet at least at one side of it, bow shock was quasi-perpendicular at least at one side of HFA, and angle between current sheet normal and solar wind velocity was large. Convection velocities of plasma within HFA were calculated by subtracting average velocity from measured ion convection velocities along spacecraft trajectory through <span class="hlt">anomaly</span>. These convection velocities viewed in coordinate system of shock normal and calculated IMF current sheet normal clearly show separation of HFA region in 3 parts: leading part, narrow central part, and trailing part. Ion velocity distributions confirm this triple structure of HFA. Thomsen et al. [1986] identified the region within HFA that they called "internal recovery". It looks like central region that we call narrow central part. Vaisberg et al. [1999] discussed separation of HFA into 2 distinct parts that correspond to leading and trailing parts. Judging from plasma convection pattern within HFAs we assumed that "internal recovery" region is the source of energy and momentum around interplanetary current sheet crossing. HFA formation mechanisms presume that HFA is formed when particles are reflected on bow shock, get swept by motional electric field and are injected back into the area. We tried to calculate the balance of energy in solar wind and within HFA to estimate what amount of reflected particles is needed for "internal recovery" area to be the real energy source. These estimations <span class="hlt">suggest</span> that this energy balance is nearly fulfilled in 4 of 5 analyzed HFAs, and does not hold for one HFA. This energy balance may be in favor of quasi-stationary nature of HFA structure. References Thomsen, M. F., J. T. Gosling, S. A. Fuselier, S. J. Bame, and C. T.

Compared with other liquids, water has many <span class="hlt">anomalies</span>. For example the density <span class="hlt">anomaly</span>: when water is cooled below 4 °C the density decreases rather than increases. This and other <span class="hlt">anomalies</span> have also been found to occur in a few other one-component liquids, sometimes in conjunction with the existence of a liquid-liquid phase transition (LLPT) between a low-density liquid (LDL) and a high-density liquid (HDL). Using simple models we explain how these <span class="hlt">anomalies</span> arise from the presence of two competing length scales. As a specific example we investigate the cut ramp <span class="hlt">potential</span>, where we show the importance of "competition" in this context, and how one length scale can sometimes be zero. When there is a clear energetic preference for either LDL or HDL for all pressures and temperatures, then there is insufficient competition between the two liquid structures and no <span class="hlt">anomalies</span> occur. From the simple models it also follows that <span class="hlt">anomalies</span> can occur without the presence of a LLPT and vice versa. It remains therefore unclear if water has a LLPT that ends in a liquid-liquid critical point (LLCP), a hypothesis that was first proposed based on simulations of the ST2 water model. We confirm the existence of a LLCP in this model using finite size scaling and the Challa-Landau-Binder parameter, and show that the LLPT is not a liquid-crystal transition, as has recently been <span class="hlt">suggested</span>. Previous research has indicated the possible existence of a LLCP in liquid silica.

Important sub-regional variations in the data are subsumed in the aggregate, <span class="hlt">potentially</span> leading to an improper handling of water resources. A combination of stream discharge characteristics and remotely sensed data can provide information that is responsive at local scales, such as watershed vulnerability to anomalous moisture conditions. We conducted an exploratory analysis of Normalized Difference Vegetation Index (NDVI) data (500 m2 resolution, 16 day) obtained from NASA's Moderate Resolution Imaging Spectroradiometer and USGS stream discharge (Q) records from over 100 unregulated streams in Tennessee for the years 2001-2012. The data sets were compiled to evaluate the vegetation response during a historical drought (Aug/Sept of 2007) within different streamflow recession index (SRI) regions. SRI can be applied as a metric for watershed storage and the ability of underlying aquifers to sustain streamflow through prolonged dry periods. The time series were filtered to remove seasonal trends, and bimonthly <span class="hlt">anomalies</span> were calculated. Each of the three NDVI and Q time series (raw, filtered, and <span class="hlt">anomaly</span>) were analyzed using cross-correlation analysis, cross-wavelet, and wavelet coherence analyses. Four SRI regions with similar land cover were chosen to spatially analyze NDVI <span class="hlt">anomalies</span> during drought. The results from the cross-correlation analysis reveal strong biannual and annual correlations between raw NDVI and raw discharge values. Correlations between NDVI <span class="hlt">anomalies</span> and discharge <span class="hlt">anomalies</span> peak at lag periods of 1 to 1.5 months with NDVI leading. The wavelet coherence analysis <span class="hlt">suggests</span> that drought dampens the monthly signal correlation between the raw values, and <span class="hlt">potentially</span> removes a strong 2 year correlation between the <span class="hlt">anomalies</span>.

Perhaps the most disturbing is the fact that when a spacecraft on a flyby trajectory approaches the Earth within 2000 km or less, it often experiences a change in total orbital energy per unit mass. Next, a secular change in the astronomical unit AU is definitely a concern. It is reportedly increasing by about 15 cm yr-1. The other two <span class="hlt">anomalies</span> are perhaps less disturbing because of known sources of nongravitational acceleration. The first is an apparent slowing of the two Pioneer spacecraft as they exit the solar system in opposite directions. Some astronomers and physicists, including us, are convinced this effect is of concern, but many others are convinced it is produced by a nearly identical thermal emission from both spacecraft, in a direction away from the Sun, thereby producing acceleration toward the Sun. The fourth <span class="hlt">anomaly</span> is a measured increase in the eccentricity of the Moon's orbit. Here again, an increase is expected from tidal friction in both the Earth and Moon. However, there is a reported unexplained increase that is significant at the three-sigma level. It is prudent to suspect that all four <span class="hlt">anomalies</span> have mundane explanations, or that one or more <span class="hlt">anomalies</span> are a result of systematic error. Yet they might eventually be explained by new physics.

Compensated terrain gravity <span class="hlt">anomalies</span> are obtained by removing the terrain-correlated free-air gravity <span class="hlt">anomalies</span>.

A degree 12 core field is removed from the data that are updated for the crustal components in the core field differences between degree 14 and 12.

Coherent components in the dusk and dawn maps are combined to estimate the magnetic <span class="hlt">anomalies</span> of the lithosphere. Long wavelength magnetic features related to lower crustal thickness variations are converted into effective magnetization contrasts by a new GLQ inversion technique.

The modeling for the Tibetan Plateau <span class="hlt">suggests</span> a demagnetized crust that is consistent with a Curie isotherm that may be upwarped into the middle crust and infers a positive density contrast related to the uplift of dense mantle material into the crust.

J.; Jokat, W.</p> <p>2006-12-01</p> <p>Mantle plumes are widely portrayed as mushroom-like `head` and thin `tail` structures that rise from a deep thermal boundary layer, generally depicted as the core-mantle boundary. This `classic` plume model has been highly successful in explaining age-progressive seamount chains as a reflection of lithospheric plate motion over thin plume `tails`. Much effort has also been spent examining evidence that may link age-progressive seamount chains to Large Igneous Provinces (LIPs), the latter being interpreted as relic plume 'head' structures. However, recent numerical modeling of thermo-chemical plumes indicates that not all plumes have simple `head` and `tail` structures (e.g., Farnetani and Samuel, 2006; Lin and van Keken, 2004, 2006). Plumes may be impinging against the base of the lithosphere in a variety of shapes and sizes, possibly episodically. Similarly, our direct age dating of the Foundation Seamount Chain, SE Pacific, <span class="hlt">suggests</span> that the narrowness of seamount chains might mask far broader underlying hotspots. Furthermore, our geochronological data show that the Galapagos Volcanic Province (GVP) developed via the progression of broad regions of concurrent dispersed volcanism that we link to a correspondingly broad mantle melting <span class="hlt">anomaly</span>. Evidence from numerical modelling and direct dating of the volcanic record is therefore <span class="hlt">suggesting</span> that hotspot melting <span class="hlt">anomalies</span> might be much broader than commonly inferred from seamount chains. Thus, the criteria for sampling the volcanic record as a test of the plume hypothesis may require modification.

These investigations test 1) the new thinking that plumes differ from the classic `head-tail` structure and 2) the inference from recent dating of Pacific seamount chains that hotspot melting <span class="hlt">anomalies</span> are much broader than <span class="hlt">suggested</span> by the dimensions of individual chains of seamounts and ridges.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/biblio/21486862','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/biblio/21486862"><span id="translatedtitle">FOLD LENS FLUX <span class="hlt">ANOMALIES</span>: A GEOMETRIC APPROACH</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Goldberg, David M.; Chessey, Mary K.; Harris, Wendy B.; Richards, Gordon T.</p> <p>2010-06-01</p> <p>We develop a new approach for studying flux <span class="hlt">anomalies</span> in quadruply imaged fold lens systems.

The concept of domain <span class="hlt">anomaly</span> is introduced as distinct from the conventional notion of <span class="hlt">anomaly</span> used in the literature. We propose a unified framework for <span class="hlt">anomaly</span> detection which exposes the multifaceted nature of <span class="hlt">anomalies</span> and <span class="hlt">suggest</span> effective mechanisms for identifying and distinguishing each facet as instruments for domain <span class="hlt">anomaly</span> detection.

The technical approach relies on suppression of <span class="hlt">potential</span> power oscillations in BWRs by detecting small <span class="hlt">anomalies</span> at an early stage and taking appropriate prognostic actions based on an anticipated operation schedule. The research utilizes a model of coupled (two-phase) thermal-hydraulic and neutron flux dynamics, which is used as a generator of time series data for <span class="hlt">anomaly</span> detection at an early stage. The model captures critical nonlinear features of coupled thermal-hydraulic and nuclear reactor dynamics and (slow time-scale) evolution of the <span class="hlt">anomalies</span> as non-stationary parameters. The time series data derived from this nonlinear non-stationary model serves as the source of information for generating the symbolic dynamics for characterization of model parameter changes that quantitatively represent small <span class="hlt">anomalies</span>. The major focus of the presented research activity was on developing and qualifying algorithms of pattern recognition for power instability based on <span class="hlt">anomaly</span> detection from time series data, which later can be used to formulate real-time decision and control algorithms for suppression of power oscillations for a variety of anticipated operating conditions.

We had already received the values of thermal neutron flux density on the surface of the Earth in the European part of Russia. The large-scale monitoring of thermal neutron flux density was carried out on structural cross-section from Drake Strait in the Atlantic Ocean to the high latitudes of Arctic. We observe the increase of Fn from 44о N to 59о N, from 0,4 to 2,9 •10-3 н/(c•cм2). The values of Fn were received in latitude Novorossiysk (0,4•10-3 n/(c•sm2)) , Moskow (0,7-1,5•10-3 n/(c•sm2)), Arhangelsk (1,3•10-3 n/(c•sm2)). High-rise dependance of the thermal neutron flux density on the surface of the Earth and in troposphere during transcontinental flights was researched. With the increasing of height from 0 to 8000 m the thermal neutron flux density rises to 180•10-3 н/(c•cм2) The measurements were carried out in latitude of Spitsbergen. The value of thermal neutron flux density on the North pole was measured. Fn is equal to 0,7•10-3 n/(c•sm2)) 890 20/ in North latitude. Recently it has been shown, that thermal neutrons render appreciable influence on alive organisms [Matveeva and etc., 2004, Masunaga S., 2001]. Abmormal increases of thermal neutron flux density are revealed in flora biogeocenosis. Daily background Fn demonstrate the specific abnormal flares for every biocenosis or biotope long-lasting (for tens of minutes) Fn - meaning during the «flares» in biogeocenosis depends on the contains of flora community and can reach 104 n/(с m2). [Plotnikova N.V., Siroeshkin A.V., 2005]. The researches of the neutron field in the World Ocean were received at the time of transatlantic expedition by the programme of RAS «Meridian» (2006, 2008). Abnormal increasing Fn had being observed in the area of equator and between 310N to 540N and 330S to 530S Moreover, the coordinates of these <span class="hlt">anomalies</span> coincide with the coordinates of the subequatorial and subtropical climatic zones. This anomalous increase Fn happens above, with an increase in phytoplankton biomass, the value of Fn is growing. Abnormal outbreak of Fn in biocenoses and over fields of phytoplankton can be associated with a well-known effect of «neutron trap» in heterogeneous environments, and the thermalization of the epithermal neutrons. Presence of the biological answer to weak streams thermal neutrons allow to assume, that these corpuscular streams are one of the "intermediaries" allowing alive organisms to feel a lot of astrogeophysical events, in addition to known climatic factors. In addition, the thermal neutron flux density is the integral characteristic,which allows to make a"neutron portrait " of the resort or the countryside. Thus, speaking about the <span class="hlt">anomalies</span> of the natural radioactive background , special attention should be paid to the level Fn and its variations, and the <span class="hlt">potential</span> impact on biological objects and human. The data obtained interaction of neutron flux and biological objects may be important for their adaptation to extreme environmental conditions. Our data <span class="hlt">suggest</span> that even in the lower layers of troposphere value thermal neutron flux (Fn) can be quite high, confirm the need for further studies to human security at the high altitude and transcontinental air flights.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/biblio/20713765','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/biblio/20713765"><span id="translatedtitle">Observational manifestations of <span class="hlt">anomaly</span> inflow</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Boyarsky, Alexey; Shaposhnikov, Mikhail</p> <p>2005-10-15</p> <p>In theories with chiral couplings, one of the important consistency requirements is that of the cancellation of a gauge <span class="hlt">anomaly</span>.

It refers to the reversal of induction arrows (as a graphical representation of the tipper transfer function, the ratio of vertical to horizontal magnetic field variations) at the northern and southern margins of the North German Basin. In spite of the many experiments carried out so far, its origin has remained ambiguous; explanations encompass a deep-crustal or even mantle source as well as the simple response to deepening of sedimentary sequences in the centre of the basin. Here, we report on modelling of new long-period magnetotelluric data collected along two profiles in NE Germany and S Sweden, with one transect crossing the Sorgenfrei-Tornquist Zone as the main boundary between Precambrian Baltica and the Palaeozoic belts of central Europe. With the exception of a few sites probably influenced by 3-D salt domes, the data allow a 2-D analysis. Resolution is reduced for large depths due to a well-conducting, saline aquifer, extending across the entire basin. The main result is that the reversal of induction arrows can largely be explained by the resistivity contrast between crystalline basement and sedimentary basin fill. Beneath Rügen island, a southward dipping conductor is interpreted to reflect an alum shale layer in Middle Cambrian-Lower Ordovician sediments. Beneath the southern basin, a moderately conductive upper mantle is modelled (although not very well resolved) which may reflect the thinning of the lithosphere as implied by seismic tomography.

In order to give a real solution to this phenomenon the IMPULSA research program has been created to develope novel technologies based on desalination of sea and brackish water using renewable sources of energy to face the problem. The Punta Banda geothermal <span class="hlt">anomaly</span> is located towards the northern part of Baja California Peninsula (Mexico). High water temperatures in some wells along the coast depicted a geothermal <span class="hlt">anomaly</span>. An audiomagnetotelluric survey was carried out in the area as a preliminary study, both to understand the process generating these anomalous temperatures and to assess its <span class="hlt">potential</span> exploitation to supply hot water to desalination plants. Among the electromagnetic methods, the audiomagnetotellurics (AMT) method is appropriated for deep groundwater and geothermal studies. The survey consisted of 27 AMT stations covering a 5 km profile along the Agua Blanca Fault. The employed array allowed us to characterize the geoelectrical properties of the main structures up to 500 m depth. Two main geoelectrical zones were identified: 1) a shallow low resistivity media located at the central portion of the profile, coinciding with the Maneadero valley and 2) two high resitivity structures bordering the conductive zone possibly related to NS faulting, already identified by previous geophysical studies.

On cooling with respect to the Wilson gauge action, instanton like structures do emerge. As cooling proceeds, these objects tend shrink and finally 'fall through the lattice.'

While historically a main semantic deficit has been widely claimed, results are mixed, with also evidence of syntactic impairment. This might be due to heterogeneity in materials and paradigms across studies, which often do not allow to tap into single linguistic components. Moreover, the interaction between linguistic and neurocognitive deficits is still unclear. In this study, we concentrated on syntactic and semantic knowledge. We employed an <span class="hlt">anomaly</span> detection task including short and long sentences with either syntactic errors violating the principles of Universal Grammar, or a novel form of semantic errors, resulting from a contradiction in the computation of the whole sentence meaning. Fifty-eight patients with diagnosis of schizophrenia were compared to 30 healthy subjects. Results showed that, in patients, only the ability to identify syntactic <span class="hlt">anomaly</span>, both in short and long sentences, was impaired. This result cannot be explained by working memory abilities or psychopathological features. These findings <span class="hlt">suggest</span> the presence of an impairment of syntactic knowledge in schizophrenia, at least partially independent of the cognitive and psychopathological profile. On the contrary, we cannot conclude that there is a semantic impairment, at least in terms of compositional semantics abilities.

Many nurses have probably never encountered this <span class="hlt">anomaly</span>, with very few able to accurately depict the pathological anatomy of the condition. As technology further develops, providers are better equipped to recognize and manage Ebstein <span class="hlt">anomaly</span>. There are important considerations for nurses when caring for an individual with Ebstein <span class="hlt">anomaly</span>. The aim of this article is to give an overview of the condition exploring the pathophysiology, how patients typically present, and how to effectively care for a patient with Ebstein <span class="hlt">anomaly</span> regarding medical and surgical courses of treatment. It is important for nurses to have a resource to reference on Ebstein <span class="hlt">anomaly</span>, and the majority of current literature is solely based for medical providers. Furthermore, Ebstein patients may be seen on a variety of units in the hospital beyond cardiology (i.e., pregnant patient with a diagnosis of Ebstein <span class="hlt">anomaly</span>).

In order to unveil some of the mechanisms involved in this pathology and to identify <span class="hlt">potential</span> biomarkers and therapeutic targets we have investigated the gene expression profile of human skeletal muscle deficient for TK2 using cDNA microarrays. Results We have analysed the whole transcriptome of skeletal muscle from patients with TK2 mutations and compared it to normal muscle and to muscle from patients with other mitochondrial myopathies. We have identified a set of over 700 genes which are differentially expressed in TK2 deficient muscle. Bioinformatics analysis reveals important changes in muscle metabolism, in particular, in glucose and glycogen utilisation, and activation of the starvation response which affects aminoacid and lipid metabolism. We have identified those transcriptional regulators which are likely to be responsible for the observed changes in gene expression. Conclusion Our data point towards the tumor suppressor p53 as the regulator at the centre of a network of genes which are responsible for a coordinated response to TK2 mutations which involves inflammation, activation of muscle cell death by apoptosis and induction of growth and differentiation factor 15 (GDF-15) in muscle and serum.

Most studies of seasonal forecast so far have focused on predicting the total amount of summer rainfall averaged over the entire India (i.e., all Indian rainfall index-AIRI). However, it is practically more useful to forecast anomalous seasonal rainfall distribution (<span class="hlt">anomaly</span> pattern) across India. The unknown science question is to what extent the anomalous rainfall pattern is predictable. This study attempted to address this question. Assessment of the 46-year (1960-2005) hindcast made by the five state-of-the-art ENSEMBLE coupled dynamic models' multi-model ensemble (MME) prediction reveals that the temporal correlation coefficient (TCC) skill for prediction of AIRI is 0.43, while the area averaged TCC skill for prediction of anomalous rainfall pattern is only 0.16. The present study aims to estimate the predictability of ISMR on regional scales by using Predictable Mode Analysis method and to develop a set of physics-based empirical (P-E) models for prediction of ISMR <span class="hlt">anomaly</span> pattern. We show that the first three observed empirical orthogonal function (EOF) patterns of the ISMR have their distinct dynamical origins rooted in an eastern Pacific-type La Nina, a central Pacific-type La Nina, and a cooling center near dateline, respectively. These equatorial Pacific sea surface temperature <span class="hlt">anomalies</span>, while located in different longitudes, can all set up a specific teleconnection pattern that affects Indian monsoon and results in different rainfall EOF patterns. Furthermore, the dynamical models' skill for predicting ISMR distribution primarily comes primarily from these three modes. Therefore, these modes can be regarded as <span class="hlt">potentially</span> predictable modes. If these modes are perfectly predicted, about 51 % of the total observed variability is <span class="hlt">potentially</span> predictable. Based on understanding the lead-lag relationships between the lower boundary <span class="hlt">anomalies</span> and the predictable modes, a set of P-E models is established to predict the principal component of each predictable mode, so that the ISMR <span class="hlt">anomaly</span> pattern can be predicted by using the sum of the predictable modes. Three validation schemes are used to assess the performance of the P-E models' hindcast and independent forecast. The validated TCC skills of the P-E model here are more than doubled that of dynamical models' MME hindcast, <span class="hlt">suggesting</span> a large room for improvement of the current dynamical prediction. The methodology proposed here can be applied to a wide range of climate prediction and predictability studies. The limitation and future improvement are also discussed.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2013AGUFM.T23G2679K','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2013AGUFM.T23G2679K"><span id="translatedtitle">The early break-up phase of the South Atlantic - magnetic <span class="hlt">anomalies</span>, volcanism and kinematics</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Koopmann, H.; Schreckenberger, B.; Franke, D.; Becker, K.; Schnabel, M.</p> <p>2013-12-01</p> <p>The South Atlantic has been generally recognized as a prime example for continental break-up with accompanying volcanic activity reflected today in massive seaward dipping reflector sequences (SDRS) in reflection as well as high velocity lower crust in refraction seismic data. The early history of the South Atlantic passive margin evolution is investigated in the view of interlaced magnetic <span class="hlt">anomalies</span> related to seafloor spreading lineations and <span class="hlt">anomalies</span> caused by seaward-dipping reflector sequences (SDRS). As the Atlantic opened from South to North, the magma-poor segments of the southernmost South Atlantic are also the oldest segments of the Ocean. Therefore, the magma-poor segments on the conjugated margins must be considered crucial in the understanding of the initial phase of spreading and rifting concluding in the opening of the South Atlantic. The interpretation of pre-M5n lineations define timing of the termination of excess breakup related volcanic activity and the transition to 'normal' seafloor spreading. Termination of magnetic <span class="hlt">anomalies</span> within SDR wedges point towards a scissor-like succession in volcanic activity from south to north, following the opening of the South Atlantic. Reflection, refraction seismic and <span class="hlt">potential</span> field data show that while the two conjugated margins share much of their structural features such as segmentation and abundant volcanism, they are by no means perfectly symmetrical. This is for example shown in shelf width, strength of the magnetic <span class="hlt">anomalies</span> or orientation of break-up related sedimentary basins. From our data, we <span class="hlt">suggest</span> changes in spreading and later rifting direction to be the cause of for these asymmetries. This directional change is also <span class="hlt">suggested</span> to be responsible for the change in margin character from magma-poor to volcanic rather than solely a spontaneous change in crustal melt-generation. New models for the magnetic response of SDRS reveal a high variability within the wedges on either side of the Atlantic and between the conjugated margins.

Despite its importance, effective tools to increase SWS are rare. Here we tested whether a hypnotic <span class="hlt">suggestion</span> to “sleep deeper” extends the amount of SWS. Design: Within-subject, placebo-controlled crossover design. Setting: Sleep laboratory at the University of Zurich, Switzerland. Participants: Seventy healthy females 23.27 ± 3.17 y. Intervention: Participants listened to an auditory text with hypnotic <span class="hlt">suggestions</span> or a control tape before napping for 90 min while high-density electroencephalography was recorded. Measurements and Results: After participants listened to the hypnotic <span class="hlt">suggestion</span> to “sleep deeper” subsequent SWS was increased by 81% and time spent awake was reduced by 67% (with the amount of SWS or wake in the control condition set to 100%). Other sleep stages remained unaffected. Additionally, slow wave activity was significantly enhanced after hypnotic <span class="hlt">suggestions</span>. During the hypnotic tape, parietal theta power increases predicted the hypnosis-induced extension of SWS. Additional experiments confirmed that the beneficial effect of hypnotic <span class="hlt">suggestions</span> on SWS was specific to the hypnotic <span class="hlt">suggestion</span> and did not occur in low <span class="hlt">suggestible</span> participants. Conclusions: Our results demonstrate the effectiveness of hypnotic <span class="hlt">suggestions</span> to specifically increase the amount and duration of slow wave sleep (SWS) in a midday nap using objective measures of sleep in young, healthy, <span class="hlt">suggestible</span> females. Hypnotic <span class="hlt">suggestions</span> might be a successful tool with a lower risk of adverse side effects than pharmacological treatments to extend SWS also in clinical and elderly populations.

Previous studies revealed cellular and molecular pathways involved in the formation of the PD plaque, and in particular the role of the myofibroblast. Aims The current work aimed to determine under normal and fibrotic conditions what differentiates PD cells from tunica albuginea (TA) and corpora cavernosa (CC) cells, by defining their global transcriptional signatures and testing in vivo whether PD cells can generate a PD like plaque Main Outcomes Measures Fibroproliferative features of PD cells and identification of related key genes as novel targets to reduce plaque size Methods Human TA, PD, and CC cells were grown with TGF?1 (TA+, PD+, CC+) or without it (TA?, PD?, CC?) and assayed by: a) immunofluorescence, western blot and RT/PCR for myofibroblast, smooth muscle cell and stem cell markers; b) collagen content; and c) DNA microarray analysis. The ability of PD+ cells to induce a PD like plaque in an immuno-suppressed rat model was assessed by Masson trichrome and Picrosirius Red. Results Upon TGF?1stimulation, collagen levels were increased by myofibroblasts in the PD+ but not in the CC+ cells. The transcriptional signature of the PD? cells identified fibroproliferative, myogenic (myofibroblasts), inflammatory, and collagen turnover genes, that differentiate them from TA? or CC? cells, and respond to TGF?1 with a PD+ fibrotic phenotype, by upregulation of IGF1, ACTG2, MYF5, ACTC1, PSTN, COL III, MMP3, and others. The PD+ cells injected into the TA of the rat induce a PD like plaque. Conclusions This <span class="hlt">suggests</span> a novel combination therapy to eliminate a PD plaque, by targeting the identified genes to: a) improve collagenase action by stimulating endogenous MMPs specific to key collagen types, and b) counteract fibromatosis by inhibiting myofibroblast generation, proliferation and/or apoptosis.

Tsunami are one of the more dramatic consequences of the seism that happen on global scale. Also in this case, tsunami, we need to improve the tools that can help the forecast of this great geophysical event and the reduction of the dramatic effects on human activities. In order to explain this topic it is necessary that several methods of investigation cooperate and create a scientific network among the complementary branches of science. In this study I <span class="hlt">suggest</span> a new strategy based on the detection of radio-<span class="hlt">anomalies</span> and the increasing of the geomagnetic background; we can apply this method two days before the earthquake until the last few hours before it. This research and the data collection started in the 2011 and it show us that more than 400 earthquakes, occurred on global scale, were preceded by the increasing value of the geomagnetic background and the emergence of radio-<span class="hlt">anomalies</span> in the frequency range from Elf to Self band. This last range is not globally accepted by the scientific community and it frequency between 0,001 and 3 Hz is included. The detection of radio-<span class="hlt">anomalies</span> data, carried out by the monitoring station Radio Emission Project, in Rome (Italy), it lets us predict a strong seismic event on global scale 6 hour before. The tsunami is a great geophysical event that can embrace several areas of Earth, for this reason the detection of radio-<span class="hlt">anomalies</span> method is useful for the experimentation in operative terms. Another important check about detection of radio-<span class="hlt">anomalies</span> was carried out before and during the strong earthquake and tsunami occurred in Japan in 2011. The radio-<span class="hlt">anomalies</span> that take over in this event and the energy released by the seaquake are linked and proportional between them.</p> </li> </ol> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_13");'>13</a></li> <li><a href="#" onclick='return showDiv("page_14");'>14</a></li> <li class="active"><span>15</span></li> <li><a href="#" onclick='return showDiv("page_16");'>16</a></li> <li><a href="#" onclick='return showDiv("page_17");'>17</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div><!-- col-sm-12 --> </div><!-- row --> </div><!-- page_15 --> <div id="page_16" class="hiddenDiv"> <div class="row"> <div class="col-sm-12"> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_14");'>14</a></li> <li><a href="#" onclick='return showDiv("page_15");'>15</a></li> <li class="active"><span>16</span></li> <li><a href="#" onclick='return showDiv("page_17");'>17</a></li> <li><a href="#" onclick='return showDiv("page_18");'>18</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div> </div> <div class="row"> <div class="col-sm-12"> <ol class="result-class" start="301"> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2015SpWea..13..484L','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2015SpWea..13..484L"><span id="translatedtitle">Space weather conditions during the Galaxy 15 spacecraft <span class="hlt">anomaly</span></span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Loto'aniu, T.

The <span class="hlt">anomaly</span> has been reported as due to a lockup of the field-programmable gate array within the spacecraft baseband communications unit during an onboard electrostatic discharge (ESD). This study evaluates the space weather conditions at the time of the Galaxy 15 <span class="hlt">anomaly</span>. The study also compares the plasma and geomagnetic environments around the <span class="hlt">anomaly</span> to space weather observations over the operational lifetime of Galaxy 15 up to the <span class="hlt">anomaly</span> time. On 5 April, the Galaxy 15 spacecraft encountered severe plasma conditions while it was in eclipse and during the subsequent <span class="hlt">anomaly</span> interval. These conditions included a massive magnetic field dipolarization that injected energetic particles from the magnetotail during a substorm observed by GOES and Time History of Events and Macroscale Interactions during Substorms satellites. Galaxy 15 was located at a near-optimum position and local time to experience the full impact of the injected energetic particles. During the largest previous storm experienced by Galaxy 15 in December 2006, evidence <span class="hlt">suggests</span> that it would not have been exposed to the same level of space weather as on 5 April 2010. Hence, while Galaxy 15 was traversing the nightside on 5 April, it likely experienced, for a short period, the most severe local plasma conditions it had encountered since launch. The most likely contributions to the ESD were interactions of the spacecraft with substorm-injected energetic particles facilitating spacecraft surface charging and deep dielectric charging.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2015OptEn..54l3114L','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2015OptEn..54l3114L"><span id="translatedtitle">Partitioned correlation model for hyperspectral <span class="hlt">anomaly</span> detection</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Lo, Edisanter</p> <p>2015-12-01</p> <p>We develop an algorithm based on a subspace model to detect <span class="hlt">anomalies</span> in a hyperspectral image.

Instead, variable induction by the ambient geomagnetic field is likely to be the principal agent for mega-scale crustal magnetic features - in both oceanic and continental settings. This revitalizes the fault-controlled susceptibility-contrast model of marine magnetic lineations, originally proposed in the late 1960s. Thus, the marine magnetic 'striping' may be ascribed to tectonic shearing and related, but variable, disintegration of the original iron-oxide mineralogy, having developed primarily along one of the two pan-global sets of orthogonal fractures and faults. In this way, fault zones (having the more advanced mineral alteration) would be characterized by relatively low susceptibility, while more moderately affected crustal sections (located between principal fault zones) would be likely to have less altered oxide mineralogy and therefore higher magnetic susceptibility. On this basis, induction by the present geomagnetic field is likely to produce oscillating magnetic field <span class="hlt">anomalies</span> with axis along the principal shear grain. The modus operandi of the alternative magneto-tectonic interpretation is inertia-driven wrenching of the global Alpine age palaeo-lithosphere - triggered by changes in Earth's rotation. Increasing sub-crustal loss to the upper mantle during the Upper Mesozoic had left the ensuing Alpine Earth in a tectonically unstable state. Thus, sub-crustal eclogitization and associated gravity-driven delamination to the upper mantle led to a certain degree of planetary acceleration which in turn gave rise to latitude-dependent, westward inertial wrenching of the global palaeo-lithosphere. During this process, 1) the thin and mechanically fragile oceanic crust were deformed into a new type of broad fold belts, and 2) the continents were subjected to relative 'in situ' rotations (mostly moderate).

Contrary to traditional studies that assume a single deep baroclinic mode for ENSO response in the tropics, the SLP <span class="hlt">anomalies</span> in the western Pacific are spatially well separated from the baroclinic signal associated with the tropospheric temperature <span class="hlt">anomalies</span> in NCEP-NCAR reanalysis, CMIP5 models, and an intermediate complexity model [a quasi-equilibrium tropical circulation model (QTCM)]. Separation of the SLP into its baroclinic and barotropic components indicates that the baroclinic mode SLP contributions are in the central and eastern Pacific (coincident with the temperature <span class="hlt">anomalies</span>), whereas the western Pacific SLP <span class="hlt">anomalies</span> arise primarily from barotropic mode contributions. In a set of QTCM experiments, we suppress <span class="hlt">anomalies</span> in baroclinic-barotropic interaction terms, i.e., <span class="hlt">anomalies</span> of the barotropic Rossby wave source, over successively wider latitudinal bands in the tropical Pacific, to diagnose their effects on the SLP <span class="hlt">anomalies</span> in the western Pacific associated with ENSO.

This <span class="hlt">suggests</span> the following pathway: interactions with SST <span class="hlt">anomalies</span> create the baroclinic mode signal in the central and Eastern Pacific, but baroclinic-barotropic interactions, arising substantially in the subtropical Pacific, create a barotropic response that is yields the SLP <span class="hlt">anomaly</span> pattern in the western Pacific.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2014EGUGA..1613849C','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2014EGUGA..1613849C"><span id="translatedtitle">Global Horizontal Irradiance <span class="hlt">Anomalies</span> in Long Term Series Over India</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Cony, Marco; Liria, Juan; Weisenberg, Ralf; Serrano, Enrique</p> <p>2014-05-01</p> <p>India has a high <span class="hlt">potential</span> for solar energy applications due to its geographic position within the Sun Belt and the large number of cloudless days in many regions of the country.

The document was entitled, '<span class="hlt">Anomalies</span> of Criticality'. '<span class="hlt">Anomalies</span>...' was a compilation of more than thirty separate and distinct examples of departures from what might be commonly expected in the field of nuclear criticality. Mr. Clayton's publication was the derivative of more than ten thousand experiments and countless analytical studies conducted world-wide on every conceivable reactor system imaginable: from fissile bearing solutions to solids, blocks to arrays of fuel rods, low-enriched uranium oxide systems to pure plutonium and highly enriched uranium systems. After publication, the document was commonly used within the nuclear fuel cycle and reactor community to train <span class="hlt">potential</span> criticality/reactor analysts, experimenters and fuel handlers on important things for consideration when designing systems with critically 'safe' parameters in mind The purpose of this paper is to re-introduce '<span class="hlt">Anomalies</span> of Criticality' to the current Criticality Safety community and to add new '<span class="hlt">anomalies</span>' to the existing compendium.

But the recent <span class="hlt">anomalies</span> largely exceed the interannual variability of the atmospheric circulation of the Arctic region. These circulation <span class="hlt">anomalies</span> are linked with the North Atlantic Oscillation <span class="hlt">suggesting</span> that they are not limited to the Arctic.

Two broad, roughly parallel, SW to NE trending triple-peaked positive <span class="hlt">anomalies</span> dominate the region, one lying south of Africa and the other north of Antarctica. Although these <span class="hlt">anomaly</span> peaks generally correspond with the Agulhas Plateau/Maud Rise, Mozambique Plateau/Astrid Ridge, and Madagascar Ridge/Conrad Rise conjugate pairs, the IM/VRM contribution from structural characteristics (i.e., crustal thickness) accounts for only about 20% of the <span class="hlt">anomaly</span> amplitudes. A spatially variable but observationally constrained NRM contribution in Cretaceous Quiet Zone (KQZ) crust is required to account for the location, shape, and amplitude contrast of these <span class="hlt">anomalies</span>. Many crustal features in the Southwest Indian Ocean near Antarctica have little geophysical data to constrain their structure but do hagve tectonic conjugates near Africa for which much more geophysical data are generally available. Using geophysical and geological constraints from one member to model the magnetization structure of its conjugate reproduces the observed Magsat reduced-to-pole <span class="hlt">anomalies</span> over both structures very well. This <span class="hlt">suggests</span> that no significant alteration in their magnetization structure has occurred since the features split. Models of these conjugate structures show that IM/VRM reproduces the Magsat <span class="hlt">anomalies</span> associated with non-KQZ crust but that both IM/VRM and a dominant NRM component are required to explain the <span class="hlt">anomalies</span> associated with KQZ crust.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.ncbi.nlm.nih.gov/pubmed/26498888','PUBMED'); return false;" href="http://www.ncbi.nlm.nih.gov/pubmed/26498888"><span id="translatedtitle">Vascular <span class="hlt">anomalies</span> of the large bowel.</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Pellino, G; Candilio, G; De Fatico, G S; Marcellinaro, R; Piccione, A; Cautiero, R; Capozzolo, A; Guerniero, R; Volpicelli, A; Reginelli, A; Corvino, A; Sciaudone, G; Canonico, S; Selvaggi, F</p> <p>2015-12-01</p> <p>Vascular <span class="hlt">anomalies</span> of the large bowel, commonly known as vascular malformations of the colon (VMC), constitute a rare but important condition, <span class="hlt">potentially</span> causing significant morbidity and mortality.

Most VMC (over 70%) are detected in the caecum and ascending colon, and affect people aged over 50 years. VMC are almost always symptomatic, presenting with lower bleeding. Endoscopy is crucial to identify and locate VMC, and to treat the lesions.

The tropical response to this forcing is variable; sediment records from the tropical Pacific indicate warm conditions in the western tropics and cooler temperatures in the east during this interval, paired with precipitation changes that <span class="hlt">suggest</span> a northward migration of the Intertropical Convergence Zone. Speleothem records and western Pacific sediment cores match this migration with a strengthened Asian monsoon, indicating a substantial reorganization in hydrology. However, the effect of these changes in zonal and meridional circulation patterns on the El Nio-Southern Oscillation (ENSO), the dominant mode of global interannual climate variability, is unclear. Conflicting hypotheses arise due to datasets that are too short to be representative of multidecadal ENSO variability trends, cannot identify individual ENSO events due to lower than annual resolution, or are located in remote, teleconnected regions. We present a suite of monthly resolved geochemical records from fossil Porites corals at Vanuatu (Tasmaloum, Espiritu Santo), a location whose climate is strongly influenced by variations in ENSO and the South Pacific Convergence Zone (SPCZ).

Slow-spreading mid-ocean-ridge segments exhibit significant crustal thinning towards transform and non-transform offsets, which is thought to arise from a three-dimensional process of buoyant mantle upwelling and melt migration focused beneath the centres of ridge segments. In contrast, fast-spreading mid-ocean ridges are characterized by smaller, segment-scale variations in crustal thickness, which reflect more uniform mantle upwelling beneath the ridge axis. Here we present a systematic study of the residual mantle Bouguer gravity <span class="hlt">anomaly</span> of 19 oceanic transform faults that reveals a strong correlation between gravity signature and spreading rate. Previous studies have shown that slow-slipping transform faults are marked by more positive gravity <span class="hlt">anomalies</span> than their adjacent ridge segments, but our analysis reveals that intermediate and fast-slipping transform faults exhibit more negative gravity <span class="hlt">anomalies</span> than their adjacent ridge segments. This finding indicates that there is a mass deficit at intermediate- and fast-slipping transform faults, which could reflect increased rock porosity, serpentinization of mantle peridotite, and/or crustal thickening. The most negative <span class="hlt">anomalies</span> correspond to topographic highs flanking the transform faults, rather than to transform troughs (where deformation is probably focused and porosity and alteration are expected to be greatest), indicating that crustal thickening could be an important contributor to the negative gravity <span class="hlt">anomalies</span> observed. This finding in turn <span class="hlt">suggests</span> that three-dimensional magma accretion may occur near intermediate- and fast-slipping transform faults.

This magnetization arises from induction and/or remanence. In a planetary context we now know that Mars has significant crustal magnetic <span class="hlt">anomalies</span> due to remanent magnetization, while the Earth has some <span class="hlt">anomalies</span> where remanence can be shown to be important. This picture, however, is less clear because of the nature and the magnitude of the geomagnetic field which is responsible for superimposed induced magnetization. Induced magnetization assumes a magnetite source, because of its much greater magnetic susceptibility when compared with other magnetic minerals. We investigated the TRM (thermoremanent magnetization) acquisition of hematite, in weak magnetic fields up to 1 mT, to determine if the remanent and induced magnetization of hematite could compete with magnetite. TRM acquisition curves of magnetite and hematite show that multi-domain hematite reaches TRM saturation (0.3 - 0.4 A sq m/kg) in fields as low as 100 microT. However, multi-domain magnetite reaches only a few percent of its TRM saturation in a field of 100 microT (0.02 - 0.06 A sq m/kg). These results <span class="hlt">suggest</span> that a mineral such as hematite and, perhaps, other minerals with significant remanence and minor induced magnetization may play an important role in providing requisite magnetization contrast. Perhaps, and especially for the Mars case, we should reevaluate where hematite and other minerals, with efficient remanence acquisition, exist in significant concentration, allowing a more comprehensive explanation of Martian <span class="hlt">anomalies</span> and better insight into the role of remanent magnetization in terrestrial crustal magnetic <span class="hlt">anomalies</span>.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://hdl.handle.net/2060/20130011182','NASA-TRS'); return false;" href="http://hdl.handle.net/2060/20130011182"><span id="translatedtitle">Data Mining for <span class="hlt">Anomaly</span> Detection</span></a></p> <p><a target="_blank" href="http://ntrs.nasa.gov/search.jsp">NASA Technical Reports Server (NTRS)</a></p> <p>Biswas, Gautam; Mack, Daniel; Mylaraswamy, Dinkar; Bharadwaj, Raj</p> <p>2013-01-01</p> <p>The Vehicle Integrated Prognostics Reasoner (VIPR) program describes methods for enhanced diagnostics as well as a prognostic extension to current state of art Aircraft Diagnostic and Maintenance System (ADMS).

Offline expert analysis is supported by data curation and data mining algorithms that can be applied in the contexts of supervised learning methods and unsupervised learning. In this report, we discuss efficient methods to implement the Kolmogorov complexity measure using compression algorithms, and run a systematic empirical analysis to determine the best compression measure. Our experiments established that the combination of the DZIP compression algorithm and CiDM distance measure provides the best results for capturing relevant properties of time series data encountered in aircraft operations.

The current revision of SR-F brought together representatives from the state radiation control programs, the Food and Drug Administration, the American Association of Physicists in Medicine, American College of Radiology, and industry. Through the course of two meetings and multiple conference calls, the Committee finalized an updated draft. The CRCPD process for the development of SSR is well established and includes internal and external peer review, review by the state Director Members, approval by the Board of Directors, and concurrence from relevant federal agencies. Once final, an SSR allows a state radiation control program to proceed through the state's own regulatory process with a vetted set of regulations, making this difficult process more efficient and effective.

The midlatitude decadal <span class="hlt">anomalies</span> associated with the Pacific Decadal Oscillation are identified, being characterized by an equivalent barotropic atmospheric low (high) pressure over a cold (warm) oceanic surface. Such a unique configuration of decadal <span class="hlt">anomalies</span> can be maintained by an unstable ocean-atmosphere interaction mechanism in the midlatitudes, which is hypothesized as follows. Associated with a warm PDO phase, an initial midlatitude surface westerly <span class="hlt">anomaly</span> accompanied with intensified Aleutian low tends to force a negative SST <span class="hlt">anomaly</span> by increasing upward surface heat fluxes and driving southward Ekman current <span class="hlt">anomaly</span>. The SST cooling tends to increase the meridional SST gradient, thus enhancing the subtropical oceanic front. As an adjustment of the atmospheric boundary layer to the enhanced oceanic front, the low-level atmospheric meridional temperature gradient and thus the low-level atmospheric baroclinicity tend to be strengthened, inducing more active transient eddy activities that increase transient eddy vorticity forcing. The vorticity forcing that dominates the total atmospheric forcing tends to produce an equivalent barotropic atmospheric low pressure north of the initial westerly <span class="hlt">anomaly</span>, intensifying the initial <span class="hlt">anomalies</span> of the midlatitude surface westerly and Aleutian low. Therefore, it is <span class="hlt">suggested</span> that the midlatitude ocean-atmosphere interaction can provide a positive feedback mechanism for the development of initial <span class="hlt">anomaly</span>, in which the oceanic front and the atmospheric transient eddy are the indispensable ingredients. Such a positive ocean-atmosphere feedback mechanism is fundamentally responsible for the observed decadal <span class="hlt">anomalies</span> in the midlatitude North Pacific ocean-atmosphere system.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=3892239','PMC'); return false;" href="http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=3892239"><span id="translatedtitle">Prevalence of dental <span class="hlt">anomalies</span> in Indian population</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pmc">PubMed Central</a></p> <p>Doni, Bharati; Kaswan, Sumita; Rahman, Farzan</p> <p>2013-01-01</p> <p>Objectives: Developmental <span class="hlt">anomalies</span> of the dentition are not infrequently observed by the dental practitioner. The aim of the present study was to determine the prevalence of dental <span class="hlt">anomalies</span> in the Indian population. Study Design: A retrospective study of 4133 panoramic radiographs of patients, who attended the Department of Oral Medicine and Radiology, Jodhpur Dental College General Hospital between September 2008 to December 2012 was done. The ages of the patients ranged from 13 to 38 years with a mean age of 21.8 years. The orthopantomographs (OPGs) and dental records were examined for any unusual finding such as congenitally missing teeth, impactions, ectopic eruption, supernumerary teeth, odontoma, dilacerations, taurodontism, dens in dente, germination and fusion, among others. Results: 1519 (36.7%) patients had at least one dental <span class="hlt">anomaly</span>. The congenitally missing teeth 673 (16.3%) had the highest prevalence, followed by impacted teeth 641 (15.5%), supernumerary teeth 51 (1.2%) and microdontia 41 (1.0%). Other <span class="hlt">anomalies</span> were found at lower prevalence ranging from transposition 7 (0.1%) to ectopic eruption 30 (0.7%). Conclusion: The most prevalent <span class="hlt">anomaly</span> in the Indian population was congenitally missing teeth (16.3%), and the second frequent <span class="hlt">anomaly</span> was impacted teeth (15.5%), whereas, macrodontia, odontoma and transposition were the least frequent <span class="hlt">anomalies</span>, with a prevalence of 0.2%, 0.2% and 0.1% respectively. While the overall prevalence of these <span class="hlt">anomalies</span> may be low, the early diagnosis is imperative for the patient management and treatment planning.

P.; Johnson, C. L.</p> <p>2011-12-01</p> <p>While the moon has is no present-day internally generated magnetic field, widespread coherently magnetized geologic units were observed with Apollo era surface and sub-satellite measurements and more recently with Lunar Prospector. However, unlike at Mars, magnetized lunar units show no clear-cut correlation with age: a few, but not all, basins of Nectarian age (3.92-3.85 Ga) exhibit magnetic <span class="hlt">anomalies</span> within the basin; some, but not all, basins exhibit magnetic <span class="hlt">anomalies</span> associated with their ejecta; and most of the crustal magnetization is in a spatially extensive region to the NW of South Pole Aitken. Recent paleomagnetic analyses have been performed on a range of sample types and ages including absolute and relative paleointensity and directional measurements. Collectively, these paleomagnetic results have been used to <span class="hlt">suggest</span> the existence of a lunar dynamo during the period ~ 3.6 - 4.2 Ga. Various mechanisms that could have produced a dynamo spanning all or part of this time interval are being investigated, such as precession, nutation, and thermally or compositionally-driven core convection. It is also apparent that shock plays an important, although still poorly-understood, role in the magnetic history of the Moon: concentrations of magnetic <span class="hlt">anomalies</span> correlate with the antipodes of four major impact basins; strong fields at Apollo 16 site those associated with the Reiner Gamma formation are attributed to basin ejecta; experiments have shown shock can demagnetize or remagnetize a material in the absence of a permanent magnetic field. Thus, despite significant recent work, no single data set, experiment, or model provides an unambiguous record of lunar magnetic evolution. A clear understanding regarding the timing of either a permanent global field or the existence of intermittent transient fields is not apparent. Here we focus on the issue of the correlation of crustal magnetic <span class="hlt">anomalies</span> with geologic age (Copernican, Eratosthenian, Imbrian, Nectarian or Pre-Nectarian) and geologic unit (basin, crater, mare or dark, and terra materials) in an effort to place constraints on the source of magnetizations and the timing of acquisition of remanence. Previous studies have investigated the correlation of magnetization with individual basin age or particular formation units (e.g. Caley Formation) but this has not been extended to the global scale, covered all lunar ages, or expanded beyond correlation with basin materials. Statistical analyses using Lunar Prospector Magnetometer and Electron Reflectometer data quantify the correlation of geologic ages and units with magnetic <span class="hlt">anomalies</span>. The majority of observable magnetic <span class="hlt">anomalies</span> are associated with visible surface units having ages that are Imbrian or Nectarian. Magnetic <span class="hlt">anomalies</span> are statistically more likely to occur in association with crater ejecta and highland material than with basin materials. We discuss whether this global interpretation is representative of magnetic <span class="hlt">anomalies</span> found NW of South Pole Aitken (SPA) basin, to help determine whether the sources of circum-SPA magnetic <span class="hlt">anomalies</span> are fundamentally different from those of magnetic <span class="hlt">anomalies</span> elsewhere on the moon.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2005AGUFMGP33B..02D','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2005AGUFMGP33B..02D"><span id="translatedtitle">Marine Magnetic <span class="hlt">Anomalies</span>, Oceanic Crust Magnetization, and Geomagnetic Time Variations</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Dyment, J.; Arkani-Hamed, J.</p> <p>2005-12-01</p> <p>Since the classic paper of Vine and Matthews (Nature, 1963), marine magnetic <span class="hlt">anomalies</span> are commonly used to date the ocean floor through comparison with the geomagnetic polarity time scale and proper identification of reversal sequences. As a consequence, the classical model of rectangular prisms bearing a normal / reversed magnetization has been dominant in the literature for more than 40 years. Although the model explains major characteristics of the sea-surface magnetic <span class="hlt">anomalies</span>, it is contradicted by (1) recent advances on the geophysical and petrologic structure of the slow-spreading oceanic crust, and (2) the observation of short-term geomagnetic time variations, both of which are more complex than assumed in the classical model. Marine magnetic <span class="hlt">anomalies</span> may also provide information on the magnetization of the oceanic crust as well as short-term temporal fluctuations of the geomagnetic field. The "anomalous skewness", a residual phase once the <span class="hlt">anomalies</span> have been reduced to the pole, has been interpreted either in terms of geomagnetic field variations or crustal structure. The spreading-rate dependence of anomalous skewness rules out the geomagnetic hypothesis and supports a spreading-rate dependent magnetic structure of the oceanic crust, with a basaltic layer accounting for most of the <span class="hlt">anomalies</span> at fast spreading rates and an increasing contribution of the deeper layers with decreasing spreading rate. The slow cooling of the lower crust and uppermost mantle and serpentinization, a low temperature alteration process which produces magnetite, are the likely cause of this contribution, also required to account for satellite magnetic <span class="hlt">anomalies</span> over oceanic areas. Moreover, the "hook shape" of some sea-surface <span class="hlt">anomalies</span> favors a time lag in the magnetization acquisition processes between upper and lower magnetic layers: extrusive basalt acquires a thermoremanent magnetization as soon as emplaced, whereas the underlying peridotite and olivine gabbro cool slowly and pass through serpentinization to bear a significant magnetization. Our analysis of the amplitude of <span class="hlt">Anomaly</span> 25 shows a sharp threshold at the spreading rate of 30 km/Ma, which corresponds to the transition between oceanic lithosphere built at axial domes and axial valleys. The twice lower amplitudes are in agreement with a much disrupted and altered basaltic layer at slow rates and a significant contribution from the deeper layers. Oceanic lithosphere created at fast and slow spreading rates therefore exhibits contrasted magnetic structures. High resolution magnetic <span class="hlt">anomaly</span> measurements carried out with deep tows and submersibles show that the magmatic (fast spreading and parts of the slow spreading) crust is a good recorder of short-term geomagnetic time variations, such as short polarity intervals, excursions, or paleointensity variations. Surface and deep-sea magnetic <span class="hlt">anomalies</span> therefore help to confirm or infirm geomagnetic findings obtained by other means. Many excursions and paleointensity variations within Brunhes and Matuyama periods are confirmed, but the "saw tooth pattern" inferred from sediment cores - a possible candidate to explain the anomalous skewness - is not, which <span class="hlt">suggests</span> a bias in the sedimentary approach.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/biblio/5587891','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/biblio/5587891"><span id="translatedtitle">Regional magnetic <span class="hlt">anomaly</span> constraints on continental breakup</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>von Frese, R.R.B.; Hinze, W.J.; Olivier, R.; Bentley, C.R.</p> <p>1986-01-01</p> <p>Continental lithosphere magnetic <span class="hlt">anomalies</span> mapped by the Magsat satellite are related to tectonic features associated with regional compositional variations of the crust and upper mantle and crustal thickness and thermal perturbations.

In support of the pathogenic <span class="hlt">potential</span> of the discovered alleles, suppression or CRISPR-mediated deletion of brf1 in zebrafish embryos recapitulated key neurodevelopmental phenotypes; in vivo complementation showed all four candidate mutations to be pathogenic in an apparent isoform-specific context. BRF1 associates with BDP1 and TBP to form the transcription factor IIIB (TFIIIB), which recruits Pol III to target genes. We show that disease-causing mutations reduce Brf1 occupancy at tRNA target genes in Saccharomyces cerevisiae and impair cell growth. Moreover, BRF1 mutations reduce Pol III–related transcription activity in vitro. Taken together, our data show that BRF1 mutations that reduce protein activity cause neurodevelopmental <span class="hlt">anomalies</span>, <span class="hlt">suggesting</span> that BRF1-mediated Pol III transcription is required for normal cerebellar and cognitive development.

W.</p> <p>2014-12-01</p> <p>Natural gas hydrates, stored in huge quantities beneath permafrost, and in submarine sediments on the continental shelf, have the <span class="hlt">potential</span> to become a vital clean-burning energy source. However, clear evidence is recorded in coastal sediments worldwide that past changes in environmental conditions have caused hydrates to become unstable and trigger both massive submarine landslides and the development of crater-like pockmarks, thereby releasing methane into the overlying seawater and atmosphere, where it acts as a powerful greenhouse gas. Arctic permafrost is thawing, and environmental changes can alter ocean circulation to warm the seafloor, causing hydrates to dissociate or dissolve in the sediments beneath. Decades of focused research provide a firm understanding of laboratory conditions under which hydrates become unstable and dissociate, and how hydrate reserves form when microbes convert organic material into methane, which can also dissolve and be carried by pore waters into the hydrate stability zone. Despite these advances, many key questions that concern both the resource <span class="hlt">potential</span> of hydrates and their role in causing environmental geohazards, are intimately tied to the more poorly understood behavior of hydrate <span class="hlt">anomalies</span>, which tend to be concentrated in the large pores of sand layers and form segregated lenses and nodules in muds. We present simple models designed to unravel the importance of the diverse physical interactions (i.e. flow focusing, free-gas infiltration, and pore-scale solubility effects) that help control how hydrate <span class="hlt">anomalies</span> form. Predicted hydrate distributions are qualitatively different when accumulation in <span class="hlt">anomalies</span> is supplied primarily by: 1. aqueous flow through sediments with enhanced permeability, 2. free-gas transport high above the three-phase stability boundary, or 3. diffusive transport along solubility gradients associated with pore-scale effects. We discuss examples that illustrate each of these distinct generation modes, in hopes of providing a framework for interpreting field observations of hydrate <span class="hlt">anomalies</span> and their geomechanical properties in terms of the history of environmental forcing that led to their development.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://hdl.handle.net/2060/20120010487','NASA-TRS'); return false;" href="http://hdl.handle.net/2060/20120010487"><span id="translatedtitle">The Impact of Devegetated Dune Fields on North American Climate During the Late Medieval Climate <span class="hlt">Anomaly</span></span></a></p> <p><a target="_blank" href="http://ntrs.nasa.gov/search.jsp">NASA Technical Reports Server (NTRS)</a></p> <p>Cook, B.

On the other hand, a reduction of SIC over DL in January is followed by an atmospheric <span class="hlt">anomaly</span> over the North Atlantic that projects on the positive phase of the East Atlantic pattern. The dynamics associated with these atmospheric <span class="hlt">anomalies</span> is described, indicating that transient-eddy activity is likely at work in settling the large-scale patterns.

The “gravity vector” theory holds that pigeons memorize the gravity vector at their home loft and deduct home direction and distance from the angular difference between memorized and actual gravity vector. However, the gravity vector is tilted by different densities in the earth crust leading to gravity <span class="hlt">anomalies</span>.

After training over shorter distances, pigeons were released from a gravitationally and geomagnetically normal site 50 km north in the same direction for both home lofts.

Partial analysis of B-horizon soils offered hope for detecting subtle hydromorphic trace-element dispersion patterns. An enzyme-based partial leach selectively removes metals from oxide coatings on the surfaces of soil materials without attacking their matrix. Most trace-element concentrations in the resulting solutions are in the part-per-trillion to low part-per-billion range, necessitating determinations by inductively coupled plasma/mass spectrometry. The resulting data show greater contrasts for many trace elements than with other techniques tested.

According to the theory (Gallardo, Meju, 2004) joint interpretation of different gradient characteristics help to localize and empathize patterns unseen on one image interpretation and gives information about the correlation of different spatial data. Values of angles between gradients and their cross and dot-product were used. This technique helps to map unseen relations between bathymetric and gravity <span class="hlt">anomaly</span> maps if they are analyzed separately. According to the method applied for the southern segment of Eastern-Brazilian coast bathymetrical and gravity <span class="hlt">anomaly</span> gradients indicates a strong source-effect relation between them. The details of the method and the obtained results are discussed. 0.2 Introduction We applied this method to investigate the correlation between bathymetric and gravity <span class="hlt">anomalies</span> at the southern segment of the Eastern-Brazilian coast. Gridded satellite global marine gravity data and bathymetrical data were used. The studied area is located at the Eastern- Brazilian coast between the 20 W and 30 W meridians and 15 S and 25 S parallels. The volcanic events responsible for the uncommon width of the continental shelf at the Abrolhos bank also were responsible for the formation of the Abrolhos islands and seamounts including the major Vitoria-Trindade chain. According to the literature this volcanic structures are expected to have a corresponding gravity <span class="hlt">anomaly</span> (McKenzie, 1976, Zembruscki, S.G. 1979). The main objective of this study is to develop and test joint image interpretation method to compare spatial data and analyze its relations. 0.3 Theory and Method 0.3.1 Data sources The bathymetrical satellite data were derived bathymetry 2-minute grid of the ETOPO2v2 obtained from NOAA's National Geophysical Data Center (http://www.ngdc.noaa.gov). The satellite marine gravity 1-minute gridded data were obtained from the Satellite Geodesy at the Scripps Institution of Oceanography, Smith & Sandwell (1997; http://topex.ucsd.edu. Gravity <span class="hlt">anomaly</span> data were re-gridded using the ETOPO2v2 grid. All calculations and maps were made using MatLab 2007 software. 0.3.2 Cross-Product Cross-product is the result of multiplication of bathymetric and gravity <span class="hlt">anomaly</span> gradient magnitudes by the sine of the angle between them. According to the definition of gradient cross-product minimal values are expected to be found in points where the angle between gradients is close to zero or where one or both of the gradient magnitudes have values close to zero. It creates an ambiguity and a problem for data interpretation since there is no exact correspondence between bathymetric structures and gravity <span class="hlt">anomalies</span>. 0.3.3 Dot-Product Dot-product is the result of multiplication of bathymetric and gravity <span class="hlt">anomaly</span> magnitudes by the cosine on the angle between them. According to the definition of dot-product, values close to zero can be generated by near perpendicular orientation of the gradients or small magnitudes of one or both gradients. So, the results are mutually increased in areas with larger magnitudes or smaller angles between gradients. Due to this mutual amplification dot-products are less affected by the ambiguity of cross-product explained above. The same statistical separation of cross-product was used to support the conclusions. 0.3.4 Statistics and Significance Criteria Statistical analysis was made in order to sort the data into two groups to reduce ambiguity effect: first group - data with magnitudes that could be considered anomalous (where the main minimizing source is the angle between the gradients and the second group - data with magnitudes variations that could be considered as (non significant or background (where cross-product value is determined by the small magnitude). It was chosen to use the mean value and standard deviation (std) to sort the data in such two groups. These values were determined for bathymetric and gravity <span class="hlt">anomaly</span> gradient magnitudes creating two data sets - one where one or both gradient magnitudes are one standard deviation larger than the mean value with a total of 7831 (anomalous) and a second one where both magnitudes differ smaller than one standard deviation from the mean value with 85584 (background ). Statistical analysis of distribution patterns for both groups was made. 0.4 Examples of Method Application 0.4.1 Map of Angles Between Gradients Figure 1 shows the map of angle values. The angle values were divided into 4 equal intervals. The statistical distribution of angles between gradient in the given intervals is the following (percents of the total): 0 to 60 - 51.39% of the values; 60 to 90 -12.08%; 90 to 120 -14.92%; 120 to 180 -21.18%. It can be seen that 51% of the gradients have a small angle between them, 72% of gradients can be considered as parallel (72%) with angles smaller than 60 or bigger than 120 between them. After statistical separation in the anomalous group almost 91% of the gradients have an angle smaller than 60 while in the background group just 48.6%. From these results we can make a conclusion that the majority of the bathymetric and gravity <span class="hlt">anomaly</span> gradients are related. Regions with higher gradient magnitudes are characterized by cosine values close to 1 (indicating a small angle between them). The size of the areas characterized by small angles between gradients exceed the size of bathymetric and gravity <span class="hlt">anomaly</span> isolines characterizing the area of influence of the structures and their effects. Regions with no significant <span class="hlt">anomalies</span> show uncorrelated value spots. 0.4.2 Map of Cross-Product The resulting map shows small spots of higher cross-product magnitudes following magnitude isolines. About 90% of the values are close to minimum. As was mentioned before, we can presume that areas where bathymetry and gravity <span class="hlt">anomaly</span> gradient cross-products have smallest magnitudes there is a good correspondence between them indicating a good correspondence between shapes. According to these results for the studied area the shapes and positions of bathymetric structures and gravity <span class="hlt">anomalies</span> are well correlated <span class="hlt">suggesting</span> strong correlation between source and its effect. 0.4.3 Map of Dot-Product The resulting map resembles bathymetric and gravity <span class="hlt">anomaly</span> isolines. All the sea mounts, banks, continental slope and other notable geomorphologic structures and gravity <span class="hlt">anomalies</span> are well delimitated in the dot-product map eliminating uncorrelated areas where gradient orientations can be considered as near perpendicular. The dot-product map of the studied area <span class="hlt">suggests</span> a strong source-effect between bathymetry and gravity <span class="hlt">anomaly</span>. 0.5 Conclusions The joint image interpretation technique uses three different criteria that are sensitive to different gradient properties. Angles between gradients are a good indicator of areas where data are related and it is not sensitive to the magnitudes of the gradients. Angles maps can be used to find areas with direct and inverse relation between mapped properties and contour areas of influence of <span class="hlt">anomalies</span> unseen on gradient magnitude maps alone. Statistical measures of distribution of angles can be an indicator of relation between data sets as show using significance criteria. Cross-product map has a spotted character of contours. To reduce the effects of the ambiguity the separation into two groups proved to be useful. It helps to separate the cross-product values that are minimized due to gradient magnitudes from those that minimize due to sine values which is a measure of correlation between them. Dot-product values contour areas where gradients are correlated. According to joint image interpretation technique applied bathymetric structures especially the volcanic seamounts and banks in the southern part of East-Brazilian Coast are closely related to the observed gravity <span class="hlt">anomalies</span> and can be interpreted as sources and effect. This technique also helps to evaluate the shape and dispersion of the gravitational effect from a bathymetrical source. 0.6 References Dehlinger P., Marine Gravity, Elsevier, 1978. Gallardo, L.

However, few studies have investigated the effects of traffic-related air pollutants with sufficient spatial accuracy. Objectives: We estimated associations between congenital <span class="hlt">anomalies</span> and exposure to traffic-related air pollution in Barcelona, Spain. Method: Cases with nonchromosomal <span class="hlt">anomalies</span> (n = 2,247) and controls (n = 2,991) were selected from the Barcelona congenital <span class="hlt">anomaly</span> register during 19942006. Land use regression models from the European Study of Cohorts for Air Pollution Effects (ESCAPE), were applied to residential addresses at birth to estimate spatial exposure to nitrogen oxides and dioxide (NOx, NO2), particulate matter with diameter ? 10 ?m (PM10), 102.5 ?m (PMcoarse), ? 2.5 ?m (PM2.5), and PM2.5 absorbance. Spatial estimates were adjusted for temporal trends using data from routine monitoring stations for weeks 38 of each pregnancy. Logistic regression models were used to calculate odds ratios (ORs) for 18 congenital <span class="hlt">anomaly</span> groups associated with an interquartile-range (IQR) increase in exposure estimates. Results: In spatial and spatiotemporal exposure models, we estimated statistically significant associations between an IQR increase in NO2 (12.2 ?g/m3) and coarctation of the aorta (ORspatiotemporal = 1.15; 95% CI: 1.01, 1.31) and digestive system defects (ORspatiotemporal = 1.11; 95% CI: 1.00, 1.23), and between an IQR increase in PMcoarse (3.6 ?g/m3) and abdominal wall defects (ORspatiotemporal = 1.93; 95% CI: 1.37, 2.73). Other statistically significant increased and decreased ORs were estimated based on the spatial model only or the spatiotemporal model only, but not both. Conclusions: Our results overall do not indicate an association between traffic-related air pollution and most groups of congenital <span class="hlt">anomalies</span>. Findings for coarctation of the aorta are consistent with those of the previous meta-analysis.

M.; Rosenberg, A. D.; Waite, A. J.; Swart, P. K.</p> <p>2010-12-01</p> <p>Low salinity plumes of Amazon and Orinoco sourced water have previously been detected around the island of Barbados. Barbados corals may therefore have the <span class="hlt">potential</span> to record salinity <span class="hlt">anomalies</span> governed by natural, climate-related, and anthropogenic changes in the Amazon and Orinoco Basin watersheds beyond the recent historic record. In order to determine whether Barbados corals record salinity variations associated with local or Amazon/Orinoco sourced signals, multiple specimens of Montastraea sp. and Siderastrea sp. coral skeletons were analyzed for stable C and O isotope and Sr/Ca variations. Corals were collected from the northwest, central-west, and southwest regions of the island to determine degree of salinity signal heterogeneity over a 5-6 year period at approximately monthly resolution. Four separate published paleotemperature equations were used to assess the importance of temperature on stable oxygen isotope composition. In situ temperature measurements obtained from NOAA show an annual sea surface temperature (SST) cycle of approximately 4 degrees Celsius off Barbados. If governed solely by SST, stable isotope data from all 8 corals in this study indicate a significantly greater annual temperature range of approximately 6 degrees Celsius. This <span class="hlt">suggests</span> that salinity related fluctuations in oxygen isotopic composition of water are an important influence on the geochemistry of Barbados corals. Some regional differences in geochemical composition of corals were apparent. Corals from the southwest of Barbados showed the clearest sub-annual isotope signal, better correlations with mean annual SST measurements, and lowest mean salinity of the regions. Corals from the central-west and northwest showed distinctly higher mean, but more variable, salinity than corals from the south. Stable carbon isotope data from southwest corals also best <span class="hlt">potentially</span> reflect the Suess Effect. Montastraea sp. corals generally show a higher paleotemperature offset from in situ values, <span class="hlt">suggesting</span> that the ability to extract salinity data from Barbados corals may be species-specific. These results may have implications for understanding local eddy patterns as Amazon-sourced water encounters Barbados.

Past findings include the ice mass loss in southern Greenland (Luthcke et al., 2006) and its acceleration in 2004 (Velicogna and Wahr, 2006), crustal dilatation by the 2004 Sumatra Earthquake (Han et al., 2006) and the postseismic movement of water in mantle (Ogawa and Heki, 2007). ENSO (El Nino and Southern Oscillation) brings about global climate impacts, together with its opposite phenomenon, La Nina. Ropelewski and Halpert (1987) showed typical precipitation patterns in ENSO years; characteristic regional-scale precipitation <span class="hlt">anomalies</span> occur in India, tropical and southern Africa and South America. Nearly opposite precipitation <span class="hlt">anomalies</span> are shown to occur in La Nina years (Ropelewski and Halpert, 1988). Here we report the detection of such precipitation <span class="hlt">anomaly</span> patterns in the GRACE monthly gravity data 2002 - 2007, which includes both La Nina (2005 fall - 2006 spring) and El Nino (2006 fall - 2007 spring) periods. We modeled the worldwide gravity time series with constant trends and seasonal changes, and extracted deviations of gravity values at two time epochs, i.e. February 2006 and 2007, and converted them into the changes in equivalent surface water mass. East Africa showed negative gravity deviation (-20.5 cm in water) in 2006 February (La Nina), which reversed to positive (18.7 cm) in 2007 February (El Nino). Northern and southern parts of South America also showed similar see-saw patterns. Such patterns closely resemble to those found meteorologically (Ropelewski and Halpert, 1987; 1988), <span class="hlt">suggesting</span> the <span class="hlt">potential</span> of GRACE as a sensor of inter-annual precipitation <span class="hlt">anomalies</span> through changes in continental water storage.

We took out the soil moisture <span class="hlt">anomalies</span> in 2006 February and 2007 February by modeling its time series in the same way as gravity, and confirmed that they are quantitatively consistent with GRACE gravity deviations.

We use a three-dimensional hybrid model of plasma and an empirical model of the Gerasimovich magnetic <span class="hlt">anomaly</span> based on Lunar Prospector observations. We examine the effects of low and high solar wind dynamic pressures on this interaction when the Gerasimovich magnetic <span class="hlt">anomaly</span> is located at nearly 20 solar zenith angle. We find that for low solar wind dynamic pressure, the crustal fields mostly deflect the solar wind plasma, form a plasma void at very close distances to the Moon (below 20 km above the surface), and reflect nearly 5% of the solar wind in charged form. In contrast, during high solar wind dynamic pressure, the crustal fields are more compressed, the solar wind is less deflected, and the lunar surface is less shielded from impinging solar wind flux, but the solar wind ion reflection is more locally intensified (up to 25%) compared to low dynamic pressures. The difference is associated with an electrostatic <span class="hlt">potential</span> that forms over the Gerasimovich magnetic <span class="hlt">anomaly</span> as well as the effects of solar wind plasma on the crustal fields during low and high dynamic pressures.

One profile was from the Atlantic Ocean in the Transatlantic Geotraverse area, one ran along latitude 35/sup 0/S in the SE Pacific, and one ran along 150/sup 0/W in the Pacific. All three profiles show the presence of intermediate wavelength (65--1500 km) magnetic <span class="hlt">anomalies</span> generated in the crust or upper mantle. The analysis of magnetic field power spectra shows that the core field becomes unimportant at about a wavelength of 1500 km. Sea floor spreading <span class="hlt">anomalies</span> should produce a maximum in power at about a wavelength of 65 km. Between these two wavelengths there should be a minimum in power which is not seen on observed records. Inverting the anomalous field to obtain some idea of the magnetization necessary to explain these intermediate wavelength magnetic <span class="hlt">anomalies</span> shows that values of magnetization in excess of 1 A m/sup -1/ are needed if the magnetized layer is as thick as the ocean crust. Alternatively, rather large thicknesses of upper mantle material with lower intensities of magnetization need to be used. The reason why such magnetization variations exist is not known.

Results A total of 50 operations were carried out: 28 horizontal partial excisions, eight vertical partial excisions, and 14 operations using other surgical methods. All cases of AVM underwent complete excision. Six cases experienced minor complications and one case of recurrence was observed. The overall average satisfaction score was 4.1 out of 5, while the satisfaction scores associated with each lesion type were 4.2 for hemangiomas, 3.9 for CMs, 4.2 for VMs, 5.0 for LMs, and 4.0 for AVMs. Conclusions It is difficult to completely excise vascular <span class="hlt">anomalies</span> that involve the vermilion. This study <span class="hlt">suggests</span> that partial excision focused on correcting the overall contour of the lips is effective and leads to satisfactory results.

A generalized elasticity theory is presented, based on the model assumption that the shear modulus of the disordered medium fluctuates randomly in space. The fluctuations are assumed to be uncorrelated and have a certain distribution (Gaussian or otherwise). Using field-theoretical techniques one is able to derive mean-field theories for the vibrational spectrum of a disordered system. The theory based on a Gaussian distribution uses a self-consistent Born approximation (SCBA),while the theory for non-Gaussian distributions is based on a coherent-<span class="hlt">potential</span> approximation (CPA). Both approximate theories appear to be saddle-point approximations of effective replica field theories. The theory gives a satisfactory explanation of the vibrational <span class="hlt">anomalies</span> in glasses. Excellent agreement of the SCBA theory with simulation data on a soft-sphere glass is reached. Since the SCBA is based on a Gaussian distribution of local shear moduli, including negative values, this theory describes a shear instability as a function of the variance of shear fluctuations. In the vicinity of this instability, a fractal frequency dependence of the density of states and the sound attenuation ? ?1+ a is predicted with a ? 1/2. Such a frequency dependence is indeed observed both in simulations and in experimental data. We argue that the observed frequency dependence stems from marginally stable regions in a glass and discuss these findings in terms of rigidity percolation.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://hdl.handle.net/2060/19850011242','NASA-TRS'); return false;" href="http://hdl.handle.net/2060/19850011242"><span id="translatedtitle">Geological reasons for change in intensity of linear magnetic <span class="hlt">anomalies</span> of the Kursk magnetic <span class="hlt">anomaly</span></span></a></p> <p><a target="_blank" href="http://ntrs.nasa.gov/search.jsp">NASA Technical Reports Server (NTRS)</a></p> <p>Zhavoronkin, I.

The residual grids generated illuminate the short-wavelength structure of the forearc. Systematic analysis of all subduction boundaries on Earth has enabled a classification of these grids with particular emphasis placed on topography and gravity <span class="hlt">anomalies</span> observed in the region above the shallow seismogenic portion of the plate interface. The isostatic compensation of these <span class="hlt">anomalies</span> is investigated using 3D calculations of the gravitational admittance and coherence. In the shallow region of the megathrust, typically within 100 km from the trench, isolated residual <span class="hlt">anomalies</span> with amplitudes of up to 2.5 km and 125 mGal are generally interpreted as accreted/subducting relief in the form of seamounts and other bathymetric features. While most of these <span class="hlt">anomalies</span>, which have radii < 50km, are correlated with areas of reduced seismicity, several in regions such as Japan and Java appear to have influenced the nucleation and/or propagation of large magnitude earthquakes. Long-wavelength (500 - >1000 km) trench-parallel forearc ridges with residual <span class="hlt">anomalies</span> of up to 1.5 km and 150 mGal are identified in approximately one-third of the subduction zones analyzed. Despite great length along strike, these ridges are less than 100 km wide and several appear uncompensated. A high proportion of arc-normal structure and the truncation/morphological transition of trench-parallel forearc ridges is explained through the identification and tracking of pre-existing structure on the over-riding and subducting plates into the seismogenic portion of the plate boundary. Spatial correlations between regions with well-defined trench-parallel forearc ridges and the occurrence of large magnitude interplate earthquakes, in addition to the uncompensated state of these ridges, <span class="hlt">suggest</span> links between the morphology of the forearc and the peak earthquake stress drop on the subduction megathrust.

M.; Zheng, L.; Gordon, R. G.; Dyment, J.</p> <p>2011-12-01</p> <p>An improved understanding of the spreading-rate dependence of anomalous skewness from magnetic <span class="hlt">anomalies</span> due to seafloor spreading will allow for better constraints on apparent polar wander paths, plate reconstructions, and the magnetic and thermal structure of oceanic lithosphere. Anomalous skewness, which is the difference between experimentally determined skewness and skewness expected from simple magnetization models with vertical reversal boundaries, has been observed to vary as a function of spreading rate, decreasing with increasing spreading rate and becoming negligible at spreading half-rates exceeding about 55 mm/a [Roest et al. 1992; Dyment et al. 1994]. In our analysis, we determine model-based estimates of anomalous skewness as a function of spreading rate for each <span class="hlt">anomaly</span>. We do so by creating many synthetic profiles using the model of Dyment and Arkani-Hamed (1995), which was specifically constructed to produce <span class="hlt">anomalies</span> with anomalous skewness consistent with observed <span class="hlt">anomalies</span>. We experimentally determine the phase shift that causes the resulting synthetic magnetic <span class="hlt">anomaly</span> to best match a profile produced from a "standard" model for <span class="hlt">anomalies</span> due to seafloor spreading that assumes simple vertical reversal boundaries. We present results for those <span class="hlt">anomalies</span> between 12r and 33r from which reliable paleomagnetic poles may <span class="hlt">potentially</span> be determined. Differences in anomalous skewness for different <span class="hlt">anomalies</span> determined at the same spreading rate can be attributed to the sequence effect, that is, the effect on the shape of a magnetic <span class="hlt">anomaly</span> above seafloor of a single polarity chron of the magnetization of neighboring blocks of lithosphere magnetized during other chrons. We find that the sequence effect is smaller than we expected with the largest difference being between the results for <span class="hlt">anomaly</span> 25r and those for <span class="hlt">anomaly</span> 33r, for which the difference is 14 degrees at a 10 mm/a half-rate. Results for other <span class="hlt">anomalies</span> lie between these two. We also infer a small outward displacement of the magnetic <span class="hlt">anomalies</span>, which-like anomalous skewness-decreases with increasing spreading rate and vanishes at half rates exceeding 55 mm/a. We find that results obtained trying to find the best match to the synthetic magnetic <span class="hlt">anomaly</span> profile are generally similar to results obtained when using the balanced-shoulder criterion for when an <span class="hlt">anomaly</span> has been successfully deskewed. The values of chron-specific (or <span class="hlt">anomaly</span>-specific) anomalous skewness that we have determined can be used to reduce the number of adjustable parameters in the determination of paleomagnetic poles from skewness data from three to two, to simply the latitude and longitude of the paleomagnetic pole.

S. Geological Survey in cooperation with the State of Minnesota has revealed a high-amplitude, linear, and narrow magnetic feature that <span class="hlt">suggests</span> a possible source of Precambrian iron-formation of economic value. For the past few years the U. S. Geological Survey has been conducting detailed geophysical studies of the midcontinent gravity <span class="hlt">anomaly</span>--a broad, high-amplitude feature that extends from Lake Superior through the States of Minnesota, Iowa, Nebraska, and part of Kansas. As part of this study an aeromagnetic survey of the southern part of the State was made in cooperation with the State of Minnesota during the summer of 1963, in which a linear high-amplitude <span class="hlt">anomaly</span> of the order of 4,000 gammas was discovered. Because of the high amplitude, the linearity, and the narrowness of the magnetic feature, it is believed the source may be Precambrian iron-formation of possible economic value. The anomalous area is in Fillmore County, approximately between the towns of Lanesboro and Peterson in the extreme southeastern part of the State. (See figures 1 and 2.) At the site of the <span class="hlt">anomaly</span>, Cambrian sedimentary rocks occur in the valley of the Root River, and Ordovician rocks (nearly flat lying) mantle the upland areas. The uplands are largely covered by glacial deposits, which are relatively thin (Paul K. Sims, written communication, 1964). Depths to the Precambrian are estimated to range from 500 feet to 1,000 feet below the surface. The aeromagnetic map shown in figure 2 was compiled from continuous magnetic profiles made along east-west flight lines 1,000 feet above ground, and spaced approximately 1 mile apart. Contour intervals of 20, 100, and 500 gammas were used depending on the intensity. The instrument for the survey was a flux-gate type magnetometer (AN/ASQ-3A) which measures total-field variations. The contour map displays variations in magnetic pattern which are typical of shallow Precambrian rocks. <span class="hlt">Anomalies</span> of the order of 1,000 gammas are shown along the east and west edges of the map. The outstanding feature is the previously mentioned linear positive <span class="hlt">anomaly</span> that trends northeast and reaches a peak of 3,960 gammas. The positive <span class="hlt">anomaly</span> is contoured from data on four consecutive profiles, but only two show high amplitudes. The high-amplitude <span class="hlt">anomalies</span> along traverses 1 and 2 are shown in figure 3. Depth calculations <span class="hlt">suggest</span> that the source of the <span class="hlt">anomaly</span> lies about 1,000 feet below the surface. Assuming a dikelike source and magnetization resulting entirely from induction in the earth's field, several calculations were made in an attempt to fit the magnetic profile taken along the line AA' (see figs. 2 and 4), considered to be a typical cross-section of the magnetic <span class="hlt">anomaly</span>. Comparisons are shown between observed and computed profiles. The fixed parameters used were (a) distance from detector to source of 2,000 ft; width of dike of 5,000 ft; dip of dike of 75?, 90?, 105? , and 120? , as shown. The best fit occurs when the dike is vertical or dips 75? to the southwest. For these cases, the susceptibility, k, is computed to be 0.016 c.g.s, units, and is comparable to k = 0.02+ calculated by Bath (1962) for the relatively unmetamorphosed iron-formation of the Main Megabi district in Minnesota where the induced magnetization was most likely the dominant magnetization. If the dominant magnetization for the <span class="hlt">anomaly</span> in Fillmore County were remanent rather than induced, the economic importance of the <span class="hlt">anomaly</span> would be greatly reduced. This <span class="hlt">anomaly</span> seems sufficiently promising to warrant further geologic and geophysical investigation. Detailed ground magnetic and electrical studies would be useful to delineate the feature. In the final analysis, however, the presence of iron-formation can be determined only by the drill.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://hdl.handle.net/2060/19850007963','NASA-TRS'); return false;" href="http://hdl.handle.net/2060/19850007963"><span id="translatedtitle">The mineralogy of global magnetic <span class="hlt">anomalies</span></span></a></p> <p><a target="_blank" href="http://ntrs.nasa.gov/search.jsp">NASA Technical Reports Server (NTRS)</a></p> <p>Haggerty, S.

The objective is to provide a global understanding of the sequence <span class="hlt">anomaly</span> detection problem and how existing techniques relate to each other. The key contribution of this survey is the classification of the existing research into three distinct categories, based on the problem formulation that they are trying to solve. These problem formulations are: 1) identifying anomalous sequences with respect to a database of normal sequences; 2) identifying an anomalous subsequence within a long sequence; and 3) identifying a pattern in a sequence whose frequency of occurrence is anomalous. We show how each of these problem formulations is characteristically distinct from each other and discuss their relevance in various application domains. We review techniques from many disparate and disconnected application domains that address each of these formulations. Within each problem formulation, we group techniques into categories based on the nature of the underlying algorithm. For each category, we provide a basic <span class="hlt">anomaly</span> detection technique, and show how the existing techniques are variants of the basic technique. This approach shows how different techniques within a category are related or different from each other. Our categorization reveals new variants and combinations that have not been investigated before for <span class="hlt">anomaly</span> detection.

Y.; Nicot, J.</p> <p>2012-12-01</p> <p>Leakage from abandoned wells and geologic faults represents one of the greatest risks to the integrity of geologic CO2 sequestration sites. Ensuring timely detection and mitigation of CO2 leakage is thus of great interest to regulators, operators, and the public. So far model-based CO2 leakage detection has not been widely tested or used. In this study, we investigated the efficacy of source identification algorithms for recovering both leakage locations and rates in the above-zone monitoring intervals by using observed pressure <span class="hlt">anomaly</span> data. For leakage rate inversion, we used ordinary least squares (OLS), truncated singular value decomposition (TSVD), and minimum relative entropy algorithm (MRE). When the leakage location(s) is unknown, inversion becomes more challenging. We coupled OLS with simulated annealing (SA) for simultaneous leakage rate and location recovery. The performance of inversion algorithms was compared while considering effects such as data noise and spatial heterogeneity. Our tests show that both OLS and TSVD can be used to recover leakage rates. TSVD is more robust than OLS and can handle large observation errors well. When the actual leaky location is unknown but is known to belong to a pool of <span class="hlt">potentially</span> leaky wells, MRE can be used to identify the actual leakage rates and leaky locations. Finally if prior information is insufficient to isolate a group of <span class="hlt">potentially</span> leaky wells, the combination of SA and OLS can be used to identify source locations among all existing wells. Our results are promising and <span class="hlt">suggest</span> that the pressure-<span class="hlt">anomaly</span>-based leakage detection can be readily incorporated into existing CO2 sequestration risk management frameworks.roblem setup bservations and identified leakage rates</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.ncbi.nlm.nih.gov/pubmed/26578241','PUBMED'); return false;" href="http://www.ncbi.nlm.nih.gov/pubmed/26578241"><span id="translatedtitle">Associated congenital <span class="hlt">anomalies</span> among cases with Down syndrome.</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Stoll, Claude; Dott, Beatrice; Alembik, Yves; Roth, Marie-Paule</p> <p>2015-12-01</p> <p>Down syndrome (DS) is the most common congenital <span class="hlt">anomaly</span> widely studied for at least 150 years. However, the type and the frequency of congenital <span class="hlt">anomalies</span> associated with DS are still controversial. Despite prenatal diagnosis and elective termination of pregnancy for fetal <span class="hlt">anomalies</span>, in Europe, from 2008 to 2012 the live birth prevalence of DS per 10,000 was 10. 2. The objectives of this study were to examine the major congenital <span class="hlt">anomalies</span> occurring in infants and fetuses with Down syndrome. The material for this study came from 402,532 consecutive pregnancies of known outcome registered by our registry of congenital <span class="hlt">anomalies</span> between 1979 and 2008. Four hundred sixty seven (64%) out of the 728 cases with DS registered had at least one major associated congenital <span class="hlt">anomaly</span>. The most common associated <span class="hlt">anomalies</span> were cardiac <span class="hlt">anomalies</span>, 323 cases (44%), followed by digestive system <span class="hlt">anomalies</span>, 42 cases (6%), musculoskeletal system <span class="hlt">anomalies</span>, 35 cases (5%), urinary system <span class="hlt">anomalies</span>, 28 cases (4%), respiratory system <span class="hlt">anomalies</span>, 13 cases (2%), and other system <span class="hlt">anomalies</span>, 26 cases (3.6%). Among the cases with DS with congenital heart defects, the most common cardiac <span class="hlt">anomaly</span> was atrioventricular septal defect (30%) followed by atrial septum defect (25%), ventricular septal defect (22%), patent ductus arteriosus (5%), coarctation of aorta (5%), and tetralogy of Fallot (3%). Among the cases with DS with a digestive system <span class="hlt">anomaly</span> recorded, duodenal atresia (67%), Hirschsprung disease (14%), and tracheo-esophageal atresia (10%) were the most common. Fourteen (2%) of the cases with DS had an obstructive <span class="hlt">anomaly</span> of the renal pelvis, including hydronephrosis. The other most common <span class="hlt">anomalies</span> associated with cases with DS were syndactyly, club foot, polydactyly, limb reduction, cataract, hydrocephaly, cleft palate, hypospadias and diaphragmatic hernia. Many studies to assess the <span class="hlt">anomalies</span> associated with DS have reported various results. There is no agreement in the literature as to which associated <span class="hlt">anomalies</span> are most common in cases with DS with associated <span class="hlt">anomalies</span>. In this study we observed a higher percentage of associated <span class="hlt">anomalies</span> than in the other reported series as well as an increase in the incidence of duodenal atresia, urinary system <span class="hlt">anomalies</span>, musculoskeletal system <span class="hlt">anomalies</span>, and respiratory system <span class="hlt">anomalies</span>, and a decrease in the incidence of anal atresia, annular pancreas, and limb reduction defects. In conclusion, we observed a high prevalence of total congenital <span class="hlt">anomalies</span> and specific patterns of malformations associated with Down syndrome which emphasizes the need to evaluate carefully all cases with Down syndrome for possible associated major congenital <span class="hlt">anomalies</span>.

If heat flow is considered as a surface expression of geothermal processes at depth, the analysis of the data set should reveal properties of those thermal processes. They do, but on a variety of scales. For this review heat flow maps are classified by 4 different horizontal scales of 10 n km (n = 1, 2, 3 and 4) and attention is focussed on the interpretation of <span class="hlt">anomalies</span> which appear with characteristic dimensions of 10 (n - 1) km in the respective representations. The largest scale of 10 4 km encompasses heat flow on a global scale. Global heat loss is 4 10 13 W and the process of sea floor spreading is the principal agent in delivering much of this heat to the surface. Correspondingly, active ocean ridge systems produce the most prominent heat flow <span class="hlt">anomalies</span> at this scale with characteristic widths of 10 3 km. Shields, with similar dimensions, exhibit negative <span class="hlt">anomalies</span>. The scale of 10 3 km includes continent wide displays. Heat flow patterns at this scale mimic tectonic units which have dimensions of a few times 10 2 km, although the thermal boundaries between these units are sometimes sharp. Heat flow <span class="hlt">anomalies</span> at this scale also result from plate tectonic processes, and are associated with arc volcanism, back arc basins, hot spot traces, and continental rifting. There are major controversies about the extent to which these surface thermal provinces reflect upper mantle thermal conditions, and also about the origin and evolution of the thermal state of continental lithosphere. Beginning with map dimensions of 10 2 km thermal <span class="hlt">anomalies</span> of scale 10 1 km, which have a definite crustal origin, become apparent. The origin may be tectonic, geologic, or hydrologic. Ten kilometers is a common wavelength of topographic relief which drives many groundwater flow systems producing thermal <span class="hlt">anomalies</span>. The largest recognized continental geothermal systems have thermal <span class="hlt">anomalies</span> 10 1 km wide and are capable of producing hundreds of megawatts of thermal energy. The smallest scale addressed in this paper is 10 1 km. Worldwide interest in exploiting geothermal systems has been responsible for a recent accumulation of heat flow data on the smallest of scales considered here. The exploration nature of the surveys involve 10's of drillholes and reveal thermal <span class="hlt">anomalies</span> having widths of 10 0 km.

To determine whether thermal <span class="hlt">anomalies</span> are statistical noise, mere meteorological conditions, or actual earthquake-related phenomena, we apply a novel approach. We use brightness temperature (top-of-atmosphere) data from thermal infrared imagery acquired at a hypertemporal (sub-hourly) interval, from geostationary weather satellites over multiple years. The length of the time series allows for analysis of meteorological effects (diurnal, seasonal or annual trends) and background variability, through the application of a combined spatial and temporal filter to distinguish extreme occurrences from trends.

The map shows a large, arcuate-shaped, negative depth <span class="hlt">anomaly</span> that is centered on the Southeast Indian Ridge and trends NNE across the Australian plate (SSE across the Antarctic plate). Within this broad scale feature, two prominent depth <span class="hlt">anomaly</span> lows are observed at 45S, 128E (the northern flank) and 54S, 125E (the southern flank). Both lows are associated with 15 Ma oceanic crust. The observed depth <span class="hlt">anomaly</span> patterns are compared with the distinctive patterns predicted by coldspot, downwelling limbs of convection cells, and thin crust models of the discordance source. The observed depth <span class="hlt">anomaly</span> does not result from absolute plate motions over a fixed coldspot source because the predicted ENE trend on the Antarctic plate is not in agreement with the SSE trend observed. The symmetric arrangement of the large-scale depth <span class="hlt">anomaly</span> and prominent lows about the ridge axis <span class="hlt">suggests</span> instead a source that has varied in strength but remained located at the ridge axis as the ridge migrated northeastward in the absolute reference frame. The organized pattern of elongated depth <span class="hlt">anomaly</span> highs and lows predicted for upper mantle convection (cells) is not evident in the observed depth <span class="hlt">anomaly</span> map. Thus a convergence of downwelling limbs of convection cells beneath the discordance is not indicated. If the source of cooler upwelling that produces less magma and hence thin crust has not varied over time, nor migrated along the ridge, then the predicted depth <span class="hlt">anomaly</span> would persist unchanged with distance from the ridge axis, and trend in the direction of relative plate motion (parallel to fracture zones). The observed depth <span class="hlt">anomaly</span> trends obliquely across fracture zones and changes in both amplitude and location relative to the ridge axis, and is therefore not consistent with cool upwelling producing thin crust. To explain the features of the depth <span class="hlt">anomaly</span> map, we propose that asthenospheric material flowing from the Amsterdam hotspot in the west, and the Balleny and Tasmantid hotspots in the east, collides within the discordance. Propagating rifts converging on the AAD provide evidence for such asthenospheric flow. Attenuated shear velocities beneath the George V fracture zone complex, and lavas geochemically identical to those from propagating rifts associated with hotspots, <span class="hlt">suggest</span> a thermal <span class="hlt">anomaly</span> producing additional asthenospheric flow east of the AAD. The increased flow and greater proximity of the discordance to the thermal <span class="hlt">anomaly</span> and hotspots to the east produce a higher pressure gradient, and hence greater driving force, which results in a westward migration of the collision zone with time. Seafloor spreading over the westward moving collision zone has produced the observed arcuate-shaped <span class="hlt">anomaly</span> with the accompanying oblique depth <span class="hlt">anomaly</span> trends.

It is no surprise that increasing our accuracy and precision in eruption prediction depends on assessing the time-progressions of all relevant precursor geophysical, geochemical, and geological phenomena, and on more frequently observing volcanoes when they become restless. The ASTER instrument on the NASA Terra Earth Observing System satellite in low earth orbit provides important capabilities in the area of detection of volcanogenic <span class="hlt">anomalies</span> such as thermal precursors and increased passive gas emissions. Its unique high spatial resolution multi-spectral thermal IR imaging data (90m/pixel; 5 bands in the 8-12um region), bore-sighted with visible and near-IR imaging data, and combined with off-nadir pointing and stereo-photogrammetric capabilities make ASTER a <span class="hlt">potentially</span> important volcanic precursor detection tool. We are utilizing the JPL ASTER Volcano Archive (http://ava.jpl.nasa.gov) to systematically examine 80,000+ ASTER volcano images to analyze (a) thermal emission baseline behavior for over 1500 volcanoes worldwide, (b) the form and magnitude of time-dependent thermal emission variability for these volcanoes, and (c) the spatio-temporal limits of detection of pre-eruption temporal changes in thermal emission in the context of eruption precursor behavior. We are creating and analyzing a catalog of the magnitude, frequency, and distribution of volcano thermal signatures worldwide as observed from ASTER since 2000 at 90m/pixel. Of particular interest as eruption precursors are small low contrast thermal <span class="hlt">anomalies</span> of low apparent absolute temperature (e.g., melt-water lakes, fumaroles, geysers, grossly sub-pixel hotspots), for which the signal-to-noise ratio may be marginal (e.g., scene confusion due to clouds, water and water vapor, fumarolic emissions, variegated ground emissivity, and their combinations). To systematically detect such intrinsically difficult <span class="hlt">anomalies</span> within our large archive, we are exploring a four step approach: (a) the recursive application of a GPU-accelerated, edge-preserving bilateral filter prepares a thermal image by removing noise and fine detail; (b) the resulting stylized filtered image is segmented by a path-independent region-growing algorithm, (c) the resulting segments are fused based on thermal affinity, and (d) fused segments are subjected to thermal and geographical tests for hotspot detection and classification, to eliminate false alarms or non-volcanogenic <span class="hlt">anomalies</span>.

S.</p> <p>2013-01-01</p> <p>Geoid data are more sensitive to density distributions deep within the Earth, thus the data are useful for studying the internal processes of the Earth leading to formation of geological structures. In this paper, we present much improved version of high resolution (1' 1') geoid <span class="hlt">anomaly</span> map of the northern Indian Ocean generated from the altimeter data obtained from Geodetic Missions of GEOSAT and ERS-1 along with ERS-2, TOPEX/POSIDEON and JASON satellites. The geoid map of the Indian Ocean is dominated by a significant low of -106 m south of Sri Lanka, named as the Indian Ocean Geoid Low (IOGL), whose origin is not clearly known yet. The residual geoid data are retrieved from the geoid data by removing the long-wavelength core-mantle density effects using recent spherical harmonic coefficients of Earth Gravity Model 2008 (EGM2008) up to degree and order 50 from the observed geoid data. The coefficients are smoothly rolled off between degrees 30-70 in order to avoid artifacts related to the sharp truncation at degree 50. With this process we observed significant improvement in the residual geoid data when compared to the previous low-spatial resolution maps. The previous version was superposed by systematic broad regional highs and lows (like checker board) with amplitude up to 12 m, though the trends of geoid in general match in both versions. These methodical artifacts in the previous version may have arisen due to the use of old Rapp's geo-<span class="hlt">potential</span> model coefficients, as well as sharp truncation of reference model at degree and order 50. Geoid <span class="hlt">anomalies</span> are converted to free-air gravity <span class="hlt">anomalies</span> and validated with cross-over corrected ship-borne gravity data of the Arabian Sea and Bay of Bengal. The present satellite derived gravity data matches well with the ship-borne data with Root Mean Square Error (RMSE) of 5.1-7.8 mGal, and this is found to be within the error limits when compared with other globally available satellite data. Spectral analysis of ship-borne and satellite data <span class="hlt">suggested</span> that the satellite gravity data have a resolution down to 16-18 km. Further, the geoid, residual geoid and gravity <span class="hlt">anomalies</span> are integrated with seismic data along two profiles in the Bay of Bengal and Arabian Sea, and inferences have been made in terms of density distributions at different depths. The new residual geoid <span class="hlt">anomaly</span> map shows excellent correlation with regional tectonic features such as Sunda subduction zone, volcanic traces (Chagos-Laccadive, Ninetyeast and 85E ridges) and mid-ocean ridge systems (Central Indian and Carlsberg ridges).</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://pubs.er.usgs.gov/publication/70011277','USGSPUBS'); return false;" href="http://pubs.er.usgs.gov/publication/70011277"><span id="translatedtitle">Statistical averaging of marine magnetic <span class="hlt">anomalies</span> and the aging of oceanic crust.</span></a></p> <p><a target="_blank" href="http://pubs.er.usgs.gov/pubs/index.jsp?view=adv">USGS Publications Warehouse</a></p> <p>Blakely, R.J.</p> <p>1983-01-01</p> <p>Visual comparison of Mesozoic and Cenozoic magnetic <span class="hlt">anomalies</span> in the North Pacific <span class="hlt">suggests</span> that older <span class="hlt">anomalies</span> contain less short-wavelength information than younger <span class="hlt">anomalies</span> in this area.

In early 2014, the tropical Pacific exhibited persistent negative SST <span class="hlt">anomalies</span> in the southeastern Pacific and positive SST <span class="hlt">anomalies</span> in north, following the pattern of the Southern Pacific Meridional Mode. In this study, we explored the role of the off-equatorial SST <span class="hlt">anomalies</span> in the 2014 prediction. Our experiments show that 40% of the amplitude error at the peak phase could be attributed to the lack of prediction of negative SST <span class="hlt">anomalies</span> in the southeastern Pacific. However, the impact of this model error is partially compensated by the absence of the positive SST <span class="hlt">anomalies</span> in the tropical western North Pacific in the model. The model response to the amplitude of negative southeastern Pacific SST <span class="hlt">anomalies</span> is nonlinear in terms of equatorial warming, because the enhanced meridional pressure gradient forces very strong meridional winds without accelerating the zonal wind component near the equator. Our study <span class="hlt">suggests</span> that reliable forecasts of ENSO strongly rely on correctly modeling the meridional SST gradient, as well as its delicate feedback with the zonal (ENSO) mode.

Here, we characterize the pharmacological properties of N-(4-((2-(trifluoromethyl)-3-hydroxy-4-(isobutyryl)phenoxy)methyl)benzyl)-1-methyl-1H-imidazole-4-carboxamide (THIIC), a structurally novel, potent, and selective allosteric <span class="hlt">potentiator</span> of human and rat mGlu2 receptors (EC(50) = 23 and 13 nM, respectively). THIIC produced anxiolytic-like efficacy in the rat stress-induced hyperthermia assay and the mouse stress-induced elevation of cerebellar cGMP and marble-burying assays. THIIC also produced robust activity in three assays that detect antidepressant-like activity, including the mouse forced-swim test, the rat differential reinforcement of low rate 72-s assay, and the rat dominant-submissive test, with a maximal response similar to that of imipramine. Effects of THIIC in the forced-swim test and marble burying were deleted in mGlu2 receptor null mice. Analysis of sleep electroencephalogram (EEG) showed that THIIC had a sleep-promoting profile with increased non-rapid eye movement (REM) and decreased REM sleep. THIIC also decreased the dark phase increase in extracellular histamine in the medial prefrontal cortex and decreased levels of the histamine metabolite tele-methylhistamine (t-MeHA) in rat cerebrospinal fluid. Collectively, these results indicate that the novel mGlu2-positive allosteric modulator THIIC has robust activity in models used to predict anxiolytic/antidepressant efficacy, substantiating, at least with this molecule, differentiation in the biological impact of mGlu2 <span class="hlt">potentiation</span> versus mGlu2/3 orthosteric agonism. In addition, we provide evidence that sleep EEG and CSF t-MeHA might function as viable biomarker approaches to facilitate the translational development of THIIC and other mGlu2 <span class="hlt">potentiators</span>.

As a result, they will encounter some aspect of the terrain environment that cannot be anticipated or otherwise accommodated by the sequences linked onboard that day. The operations team then must correct the problem by planning then commanding the execution of a different drive the next day. Often other aspects of the operation on the surface of Mars: environmental changes, component degradation, errors in sequence design or execution, etc., lead to <span class="hlt">anomalies</span> which must be addressed before normal operations can resume. The operational design that makes it possible to recover from a driving error each day also reduces the time needed to recover from <span class="hlt">anomalies</span>. As an example of the efficiency achieved, less than 5% (about 30 sols out of 700 sols of operations) of the time on the surface has been devoted to recovery from <span class="hlt">anomalies</span> for each vehicle. In this paper the major <span class="hlt">anomalies</span> experienced by the MER rovers will be recounted and the streamlined approaches to addressing these problems described. The operational flexibility developed for these missions is also a function of the system design that anticipated a number of likely faults and conditions arising from uncertainty in sequence execution and environmental change. This design will be described as well as the considerations in operation that motivated this design. These considerations will likely be present in any future surface mission.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://eric.ed.gov/?q=Fuzzy+AND+logic&pg=3&id=ED513684','ERIC'); return false;" href="http://eric.ed.gov/?q=Fuzzy+AND+logic&pg=3&id=ED513684"><span id="translatedtitle"><span class="hlt">Anomaly</span> Detection Techniques for Ad Hoc Networks</span></a></p> <p><a target="_blank" href="http://www.eric.ed.gov/ERICWebPortal/search/extended.jsp?_pageLabel=advanced">ERIC Educational Resources Information Center</a></p> <p>Cai, Chaoli</p> <p>2009-01-01</p> <p><span class="hlt">Anomaly</span> detection is an important and indispensable aspect of any computer security mechanism.

It is a right ventricular myopathy with failure of tricuspid valve delamination and highly variable tricuspid valve morphology that usually results in severe regurgitation. It is the only congenital heart lesion that has a range of clinical presentations, from the severely symptomatic neonate to an asymptomatic adult. Neonatal operation has high operative mortality, whereas operation performed beyond infancy and into adulthood has low operative mortality. Late survival and quality of life for hospital survivors are excellent for the majority of patients in all age brackets. Atrial tachyarrhythmias are the most common late complication. There have been more techniques of tricuspid repair reported in the literature than any other congenital or acquired cardiac lesion. This is largely due to the infinite anatomic variability encountered with this <span class="hlt">anomaly</span>. The cone reconstruction of Ebstein <span class="hlt">anomaly</span> can achieve near anatomic restoration of the tricuspid valve anatomy. Early and intermediate results with these repairs are promising. Reduced right ventricular function continues to be a challenge for some patients, as is the need for reoperation for recurrent tricuspid regurgitation. The purpose of this article is to outline the current standard of care for diagnosis and treatment of Ebstein <span class="hlt">anomaly</span> and describe innovative strategies to address poor right ventricular function and associated right-sided heart failure.

The resulting orthogonal perturbation patterns are designed such that they pick up typical balanced <span class="hlt">anomaly</span> structures in space and time and between variables.

The choices of a reference state for defining the initial <span class="hlt">anomalies</span> are such that either perturbations on seasonal timescales and or on interannual timescales are constructed. These project a-priori only the slow modes of the ocean physical processes, such that the disturbances grow mainly in the Western Boundary Currents, in the Antarctic Circumpolar Current and the El Nino Southern Oscillation regions. An additional set of initial conditions is designed to fit in a least square sense data from global ocean reanalysis. Applying the AT produced sets of disturbances to oceanic initial conditions initialized by observations of the MPIOM-ESM coupled model on T63L47/GR15 resolution, four ensemble and one hind-cast experiments were performed. The weighted total energy norm is used to monitor the amplitudes and rates of the fastest growing error modes.

If the symmetry of the system is unitary, then a formal way to determine whether a d -dim theory must be a boundary or not, is to couple this theory to a gauge field (or to "gauge" its symmetry), and check if there is a gauge <span class="hlt">anomaly</span>. In this paper we discuss the following question: Can the boundary of a SPT state be driven into a fully gapped topological order which preserves all the symmetries? We argue (conjecture) that if the gauge <span class="hlt">anomaly</span> of the boundary is "perturbative," then the boundary must remain gapless; while if the boundary only has global gauge <span class="hlt">anomaly</span> but no perturbative <span class="hlt">anomaly</span>, then it is possible to gap out the boundary by driving it into a topological state, when d ≥2 . We will demonstrate this conjecture with two examples: (1) the 3 d spin-1/2 chiral fermion with the well-known Witten's global <span class="hlt">anomaly</span> [Phys. Lett. 117, 324 (1982), 10.1016/0370-2693(82)90728-6], which can be realized on the boundary of a 4 d topological superconductor with SU(2) or U (1 ) ⋊Z2 symmetry; and (2) the 4 d boundary of a 5 d topological superconductor with the same symmetry. We show that these boundary systems can be driven into a fully gapped Z2 N topological order with topological degeneracy, but this Z2 N topological order cannot be future driven into a trivial confined phase that preserves all the symmetries due to some special properties of its topological defects. Our study also leads to exotic states of matter in pure 3 d space.</p> </li> </ol> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_21");'>21</a></li> <li><a href="#" onclick='return showDiv("page_22");'>22</a></li> <li class="active"><span>23</span></li> <li><a href="#" onclick='return showDiv("page_24");'>24</a></li> <li><a href="#" onclick='return showDiv("page_25");'>25</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div><!-- col-sm-12 --> </div><!-- row --> </div><!-- page_23 --> <div id="page_24" class="hiddenDiv"> <div class="row"> <div class="col-sm-12"> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_21");'>21</a></li> <li><a href="#" onclick='return showDiv("page_22");'>22</a></li> <li><a href="#" onclick='return showDiv("page_23");'>23</a></li> <li class="active"><span>24</span></li> <li><a href="#" onclick='return showDiv("page_25");'>25</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div> </div> <div class="row"> <div class="col-sm-12"> <ol class="result-class" start="461"> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.ncbi.nlm.nih.gov/pubmed/11623670','PUBMED'); return false;" href="http://www.ncbi.nlm.nih.gov/pubmed/11623670"><span id="translatedtitle">Environmental imperatives reconsidered: demographic crises in western North America during the medieval climatic <span class="hlt">anomaly</span>.</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Jones, T L; Brown, G M; Raab, L M; McVickar, J L; Spaulding, W G; Kennett, D J; York, A; Wlaker, P L</p> <p>1999-04-01</p> <p>Review of late Holocene paleoenvironmental and cultural sequences from four regions of western North America show striking correlations between drought and changes in subsistence, population, exchange, health, and interpersonal violence during the Medieval Climatic <span class="hlt">Anomaly</span> (A.D. 800-1350).

This effect was consistent with hypotheses <span class="hlt">suggesting</span> an underlying resonance phenomenon. We report here, in a parallel series of investigations on the same model system, that the incidence of regeneration <span class="hlt">anomalies</span> presenting as tumor-like protuberances also increases significantly (P < .001) in association with exposure to weak 60 Hz magnetic fields, with peak intensities ranging between 1.0 and 80.0 microT. These <span class="hlt">anomalies</span> often culminate in the complete disaggregation of the organism. Similar to regeneration rate effects, the incidence of regeneration <span class="hlt">anomalies</span> is specifically dependent upon the planaria possessing a fixed orientation with respect to the applied magnetic field vectors. However, unlike the regeneration rate effects, the AC magnetic field alone, in the absence of any measurable DC field, is capable of producing these <span class="hlt">anomalies</span>. Moreover, the incidence of regeneration <span class="hlt">anomalies</span> follows a clear dose-response relationship as a function of AC magnetic field intensity, with the threshold for induced electric field intensity estimated at 5 microV/m. The addition of either 51.1 or 78.4 microT DC magnetic fields, applied in parallel combination with the AC field, enhances the appearance of <span class="hlt">anomalies</span> relative to the 60 Hz AC field alone, but only at certain AC field intensities. Thus, whereas our previous study of regeneration rate effects appeared to involve exclusively resonance interactions, the regeneration <span class="hlt">anomalies</span> reported here appear to result primarily from Faraday induction coupling. These results together with those reported previously point to two distinct physiological effects produced in regenerating planaria by exposure to weak extremely-low-frequency (ELF) magnetic fields. They further <span class="hlt">suggest</span> that the planarian, which has recently been identified elsewhere as an excellent system for use in teratogenic investigations involving chemical teratogens, might be used similarly in teratogenic investigations involving ELF magnetic fields.

By micro-<span class="hlt">anomalies</span>, we primarily refer to micro-cracks of size 10-100 ?m (depending on the material), while macro-level response variables imply, e.g., strains, strain energy density of macro-level structures (typical size often varying in the order of 10-100 m). The micro-<span class="hlt">anomalies</span> referred above are not discernible to the naked eyes. Nevertheless, they can cause catastrophic failures of structural systems due to fatigue cyclic loading that results in initiation of fatigue cracks. Analysis of such precursory state of internal damage evolution, before amacro-crack visibly appears (say, size of a few cms), is beyond the scope of the conventional crack propagation analysis, e.g., classical fracture mechanics. The present work addresses this issue in a certain sense by incorporating the effects of micro-cracks into the macro-scale constitutive material properties (e.g., constitutive elasticity tensors) within a probabilistic formalism based on random matrix theory, maximum entropy principle, and principles of minimum complementary energy and minimum <span class="hlt">potential</span> energy. Distinct differences are observed in the macro-level response characteristics depending on the presence or absence of micro-cracks. This particular feature can now be used to reliably detect micro-cracks from experimental measurements of macro-observables. The present work, therefore, further proposes an efficient and robust optimization scheme: (1) to identify locations of micro-cracks in macroscopic structural systems, say, in an aircraft wing which is of the size of 10- 100 m, and (2) to determine the weakened (due to the presence of micro-cracks) macroscopic material properties which will be useful in predicting the remaining useful life of structural systems. The proposed optimization scheme achieves better convergence rate and accuracy by exploiting positive-definite structure of the macroscopic constitutive matrices.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2014AGUFMNG41B..07D','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2014AGUFMNG41B..07D"><span id="translatedtitle">Analyzing Global Climate System Using Graph Based <span class="hlt">Anomaly</span> Detection</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Das, K.; Agrawal, S.; Atluri, G.; Liess, S.; Steinbach, M.; Kumar, V.</p> <p>2014-12-01</p> <p>Climate networks have been studied for understanding complex relationships between different spatial locations such as community structures and teleconnections. Analysis of time-evolving climate networks reveals changes that occur in those relationships over time and can provide insights for discovering new and complex climate phenomena. We have recently developed a novel data mining technique to discover anomalous relationships from dynamic climate networks. The algorithms efficiently identifies anomalous changes in relationships that cause significant structural changes in the climate network from one time instance to the next. Using this technique we investigated the presence of <span class="hlt">anomalies</span> in precipitation networks that were constructed based on monthly averages of precipitation recorded at .5 degree resolution during the time period 1982 to 2002. The precipitation network consisted of 10-nearest neighbor graphs for every month's data. Preliminary results on this data set indicate that we were able to discover several <span class="hlt">anomalies</span> that have been verified to be related to or as the outcome of well known climate phenomena. For instance, one such set of <span class="hlt">anomalies</span> corresponds to transition from January 1994 (normal conditions) to January 1995 (El-Nino conditions) and include events like worst droughts of the 20th century in Australian Plains, very high rainfall in southeast Asian islands, and drought-like conditions in Peru, Chile, and eastern equatorial Africa during that time period. We plan to further apply our technique to networks constructed out of different climate variables such as sea-level pressure, surface air temperature, wind velocity, 500 geo-<span class="hlt">potential</span> height etc. at different resolutions. Using this method we hope to develop deeper insights regarding the interactions of multiple climate variables globally over time, which might lead to discovery of previously unknown climate phenomena involving heterogeneous data sources.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2007SPIE.6579E..0ER','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2007SPIE.6579E..0ER"><span id="translatedtitle">Steganography <span class="hlt">anomaly</span> detection using simple one-class classification</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Rodriguez, Benjamin M.; Peterson, Gilbert L.; Agaian, Sos S.</p> <p>2007-04-01</p> <p>There are several security issues tied to multimedia when implementing the various applications in the cellular phone and wireless industry. One primary concern is the <span class="hlt">potential</span> ease of implementing a steganography system. Traditionally, the only mechanism to embed information into a media file has been with a desktop computer. However, as the cellular phone and wireless industry matures, it becomes much simpler for the same techniques to be performed using a cell phone. In this paper, two methods are compared that classify cell phone images as either an <span class="hlt">anomaly</span> or clean, where a clean image is one in which no alterations have been made and an anomalous image is one in which information has been hidden within the image. An image in which information has been hidden is known as a stego image. The main concern in detecting steganographic content with machine learning using cell phone images is in training specific embedding procedures to determine if the method has been used to generate a stego image. This leads to a possible flaw in the system when the learned model of stego is faced with a new stego method which doesn't match the existing model. The proposed solution to this problem is to develop systems that detect steganography as <span class="hlt">anomalies</span>, making the embedding method irrelevant in detection. Two applicable classification methods for solving the <span class="hlt">anomaly</span> detection of steganographic content problem are single class support vector machines (SVM) and Parzen-window. Empirical comparison of the two approaches shows that Parzen-window outperforms the single class SVM most likely due to the fact that Parzen-window generalizes less.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/biblio/21460040','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/biblio/21460040"><span id="translatedtitle">NEUTRON-RICH CHROMIUM ISOTOPE <span class="hlt">ANOMALIES</span> IN SUPERNOVA NANOPARTICLES</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Dauphas, N.; Remusat, L.; Papanastassiou, D.

Traces of such nucleosynthesis are found in primitive meteorites in the form of variations in the isotopic abundance of {sup 54}Cr, the most neutron-rich stable isotope of chromium. The hosts of these isotopic <span class="hlt">anomalies</span> must be presolar grains that condensed in the outflows of SNe, offering the opportunity to study the nucleosynthesis of iron-peak nuclei in ways that complement spectroscopic observations and can inform models of stellar evolution. However, despite almost two decades of extensive search, the carrier of {sup 54}Cr <span class="hlt">anomalies</span> is still unknown, presumably because it is fine grained and is chemically labile. Here, we identify in the primitive meteorite Orgueil the carrier of {sup 54}Cr <span class="hlt">anomalies</span> as nanoparticles (<100 nm), most likely spinels that show large enrichments in {sup 54}Cr relative to solar composition ({sup 54}Cr/{sup 52}Cr ratio >3.6 x solar). Such large enrichments in {sup 54}Cr can only be produced in SNe. The mineralogy of the grains supports condensation in the O/Ne-O/C zones of an SNII, although a Type Ia origin cannot be excluded. We <span class="hlt">suggest</span> that planetary materials incorporated different amounts of these nanoparticles, possibly due to late injection by a nearby SN that also delivered {sup 26}Al and {sup 60}Fe to the solar system. This idea explains why the relative abundance of {sup 54}Cr and other neutron-rich isotopes vary between planets and meteorites. We anticipate that future isotopic studies of the grains identified here will shed new light on the birth of the solar system and the conditions in SNe.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.ncbi.nlm.nih.gov/pubmed/24473551','PUBMED'); return false;" href="http://www.ncbi.nlm.nih.gov/pubmed/24473551"><span id="translatedtitle">MedMon: securing medical devices through wireless monitoring and <span class="hlt">anomaly</span> detection.</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Zhang, Meng; Raghunathan, Anand; Jha, Niraj K</p> <p>2013-12-01</p> <p>Rapid advances in personal healthcare systems based on implantable and wearable medical devices promise to greatly improve the quality of diagnosis and treatment for a range of medical conditions. However, the increasing programmability and wireless connectivity of medical devices also open up opportunities for malicious attackers. Unfortunately, implantable/wearable medical devices come with extreme size and power constraints, and unique usage models, making it infeasible to simply borrow conventional security solutions such as cryptography. We propose a general framework for securing medical devices based on wireless channel monitoring and <span class="hlt">anomaly</span> detection. Our proposal is based on a medical security monitor (MedMon) that snoops on all the radio-frequency wireless communications to/from medical devices and uses multi-layered <span class="hlt">anomaly</span> detection to identify <span class="hlt">potentially</span> malicious transactions. Upon detection of a malicious transaction, MedMon takes appropriate response actions, which could range from passive (notifying the user) to active (jamming the packets so that they do not reach the medical device). A key benefit of MedMon is that it is applicable to existing medical devices that are in use by patients, with no hardware or software modifications to them. Consequently, it also leads to zero power overheads on these devices. We demonstrate the feasibility of our proposal by developing a prototype implementation for an insulin delivery system using off-the-shelf components (USRP software-defined radio). We evaluate its effectiveness under several attack scenarios. Our results show that MedMon can detect virtually all naive attacks and a large fraction of more sophisticated attacks, <span class="hlt">suggesting</span> that it is an effective approach to enhancing the security of medical devices.

The first extends from Station ALOHA (22.78N) to the equator at 1000-1500 m and lies below the maximum apparent oxygen utilization and nutrient (N, P) concentrations. The feature is not supported by vertical export processes, but instead corresponds with the lateral dilution field of ? 3He derived from the Loihi seamount, Hawaii, though a sediment source associated with the Hawaiian Island Chain cannot be entirely ruled out. The second, deeper (2000-3000 m) <span class="hlt">anomaly</span> occurs in tropical South Pacific waters (7S) and also does not correlate with the depths of maximum nutrient concentrations or apparent oxygen utilization, but it does coincide closely with ? 3He emanating from the East Pacific Rise, more than 5000 km to the east. We hypothesize that these <span class="hlt">anomalies</span> represent the long-range (>2000 km) transport of hydrothermal iron residuals, stabilized against scavenging by complexation with excess organic ligands in the plume source regions. Such trace leakage of hydrothermal iron to distal plume regions would have been difficult to identify in most hydrothermal vent mapping studies because low analytical detection limits were not needed for the proximal plume regions. These findings <span class="hlt">suggest</span> that hydrothermal activity may represent a major source of dissolved iron throughout the South Pacific deep basin today, as well as other regions having high mid-ocean spreading rates in the geologic past. In particular, we hypothesize that high spreading rates along the South Atlantic and Southern Ocean mid-oceanic ridges, combined with the upwelling ventilation of these distal hydrothermal plumes, may have increased ocean productivity and carbon export in the Southern Ocean.

A model was used to decompose spatiotemporal SWC into time-stable pattern (i.e., temporal mean), space-invariant temporal <span class="hlt">anomaly</span>, and space-variant temporal <span class="hlt">anomaly</span>. This model was compared with a previous model that decomposes spatiotemporal SWC into spatial mean and spatial <span class="hlt">anomaly</span>.

We aimed to test the hypothesis that underlying (i.e., time-invariant) spatial patterns exist in the space-variant temporal <span class="hlt">anomaly</span> at the small watershed scale, and to examine the advantages of the TA model over the SA model in terms of estimation of spatially distributed SWC. For this purpose, a SWC dataset of near surface (0-0.2 m) and root zone (0-1.0 m) from a small watershed scale in the Canadian prairies was analyzed. Results showed that underlying spatial patterns exist in the space-variant temporal <span class="hlt">anomaly</span> because of the permanent controls of "static" factors such as depth to the CaCO3 layer and organic carbon content. Combined with time stability analysis, the TA model improved estimation of spatially distributed SWC over the SA model because the latter failed to capture the space-variant temporal <span class="hlt">anomaly</span> which accounted for non-negligible amounts of spatial variance in SWC. The outperformance was greater when SWC deviated from intermediate conditions, especially for dry conditions.

However, whether these structural <span class="hlt">anomalies</span> are driven by dyslexia (disorder-specific effects), absolute reading performance (performance-dependent effects), and/or further influenced by age (maturation-sensitive effects) remains elusive. To help disentangle these sources, the current study used a novel disorder (dyslexia vs. control) by maturation (younger vs. older) factorial design in 48 Chinese children who were carefully matched. This design not only allows for direct comparison between dyslexics versus controls matched for chronological age and reading ability, but also enables examination of the influence of maturation and its interaction with dyslexia. Voxel-based morphometry (VBM) showed that dyslexic children had reduced regional gray matter volume in the left temporo-parietal cortex (spanning over Heschl's gyrus, planum temporale and supramarginal gyrus), middle frontal gyrus, superior occipital gyrus, and reduced regional white matter in bilateral parieto-occipital regions (left cuneus and right precuneus) compared with both age-matched and reading-level matched controls. Therefore, maturational stage-invariant neurobiological signatures of dyslexia were found in brain regions that have been associated with impairments in the auditory/phonological and attentional systems. On the other hand, maturational stage-dependent effects on dyslexia were observed in three regions (left ventral occipito-temporal cortex, left dorsal pars opercularis and genu of the corpus callosum), all of which were previously reported to be involved in fluent reading and its development. These striking dissociations collectively <span class="hlt">suggest</span> <span class="hlt">potential</span> atypical developmental trajectories of dyslexia, where underlying mechanisms are currently unknown but may be driven by interactions between genetic and/or environmental factors. In summary, this is the first study to disambiguate maturational stage on neuroanatomical <span class="hlt">anomalies</span> of dyslexia in addition to the effects of disorder, reading performance and maturational stage on neuroanatomical <span class="hlt">anomalies</span> of dyslexia, despite the limitation of a relatively small sample-size. These results will hopefully encourage future research to place greater emphasis on taking a developmental perspective to dyslexia, which may, in turn, further our understanding of the etiological basis of this neurodevelopmental disorder, and ultimately optimize early identification and remediation.

Observations from a grid of shallow, maximum-rise piezometers indicate that perching on this clay layer is common. However, flow measurements from an interflow-interception trench indicate that lateral flow is rare and most soil water percolates through the clay layer.

We used ground penetrating radar (GPR) to map the soil structure and <span class="hlt">potential</span> <span class="hlt">anomalies</span>, such as root holes, down to two meters depth at three 1010-m plots. At each plot, a 110-m trench was later back-hoe excavated along a transect that showed the most <span class="hlt">anomalies</span> on the GPR maps. Each trench was excavated at 0.5-m intervals until the clay layer was reached (two plots were excavated to a final depth of 0.875 m and the third plot was excavated to a final depth of 1.0 m). At each interval, compact constant-head permeameters (CCHPs) were used to measure in-situ hydraulic conductivities in the clay-loam matrix and in any visually apparent <span class="hlt">anomalies</span>. Conductivity was also estimated using a second 110-m transect of CCHP measurements taken within randomly placed augur holes. Additional holes targeted GPR <span class="hlt">anomalies</span>.

E.</p> <p>2012-02-01</p> <p>The Pioneer <span class="hlt">anomaly</span> is one of the most important problems in modern physics. The observed blueshift of the Doppler signals coming back from the space probes Pioneer 10 and 11 is interpreted as being due to an anomalous acceleration a_p = (8.74 1.33) 10-8 cm s-2 towards the Sun. In this paper the blueshift is explained by the frequency shifts of the receivers. These frequency shifts result from an increase in elementary particle masses in time, the rate of increase being tied up with the present-day Hubble parameter H_0. The result is that the seeming acceleration a_p is the product of H_0 and the velocity of light. Taking new physics into consideration, this paper presents a new explanation of the Pioneer <span class="hlt">anomaly</span> based on the assumption that the Universe is eternal and infinite without expansion or contraction.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2015JHEP...11..216R','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2015JHEP...11..216R"><span id="translatedtitle">Holographic trace <span class="hlt">anomaly</span> and local renormalization group</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Rajagopal, Srivatsan; Stergiou, Andreas; Zhu, Yechao</p> <p>2015-11-01</p> <p>The Hamilton-Jacobi method in holography has produced important results both at a renormalization group (RG) fixed point and away from it.

While developing the CKEF, <span class="hlt">anomaly</span> detection has been clearly recognized as an important aspect requiring R&D. An activity has thus been undertaken to implement, within the CKEF, a proof-of-concept prototype of a rule-based expert system to support the analysts regarding this aspect. This expert system has to perform automated reasoning and output recommendations (or alerts) about maritime <span class="hlt">anomalies</span>, thereby supporting the identification of vessels of interest and threat analysis. The system must contribute to a lower false alarm rate and a better probability of detection in drawing operator's attention to vessels worthy of their attention. It must provide explanations as to why the vessels may be of interest, with links to resources that help the operators dig deeper. Mechanisms are necessary for the analysts to fine tune the system, and for the knowledge engineer to maintain the knowledge base as the expertise of the operators evolves.
