  3. Did Herbert Spencer have reading epilepsy?

    PubMed

    Raitiere, Martin N

    2011-10-01

    Herbert Spencer, the nineteenth-century philosopher, has frequently been dismissed as a "fantastical hypochondriac" (as his most recent biographer, Mark Francis, terms him). Yet he left a record in his Autobiography of symptoms that suggest a very different diagnosis. Abruptly at age 35, he found that the activity of reading, previously indulged in without difficulty, triggered paroxysmal episodes of disturbing "head-sensations" including "giddiness" (so Spencer described them); these severely curtailed his ability to carry out his philosophical studies. Of all possible explanations for such episodes, none seems as likely as reading epilepsy. Enduring preconceptions about Spencer's presumed neurosesmay have kept modern historians from appreciating that Spencer suffered from a legitimate, if esoteric, neurological malady. PMID:22003861

  9. Phytoplankton bloom in Spencer Gulf, South Australia

    NASA Technical Reports Server (NTRS)

    2002-01-01

    Summer in southern Australia is the dry season, and in this true-color MODIS image of South Australia and the Spencer Gulf from October 20,2001, the area's vegetation is losing much of the lushness it possessed in the winter rainy season (See image from September 19, 2001). In southern hemisphere summer, the high pressure systems that dominate the continent's weather move south, and block the rain-bearing westerly winds. The resulting changes in seasonal rainfall are extreme. Many of the rivers are impermanent, and flow into dry or impermanent salt lakes, such as Lake Torrens (long, thin lake bed, roughly in the center of the image), and Lake Eyre (pink and white lake bed to the northwest of Torrens). Between the Eyre Peninsula (lower left) and the Yorke Peninsula further east lies the Spencer Gulf, showing the blue-green swirls that indicate a phytoplankton bloom. Australia gets less rainfall than any continent except Antarctica, and the low and seasonal flows contribute to problems with salinity and algal blooms in the continent's surface waters.

  10. Phytoplankton bloom in Spencer Gulf, Southern Australia

    NASA Technical Reports Server (NTRS)

    2002-01-01

    South Australia occupies the center of the Australian continent. The deserts of the interior give way to more fertile land along the coast of the Southern Ocean. This true-color MODIS image from September 17, 2001, shows the marked contrast between the country's arid interior--where seasonal salt lakes stand out in white against the deserts' vast, red expanse--and the coastal regions, including Spencer Gulf, to the lower left of the image's center. The characteristic blue-green swirls of a phytoplankton bloom can be seen in the Gulf and southeastward along the coast. To Spencer Gulf's east, the brownish-gray pixels on the eastern coast of the Gulf of St. Vincent indicate the location of the city of Adelaide, the region's capital. The large dark areas that stand out amid the green vegetation do not indicate areas where vegetation had been damaged or burned. In fact, the opposite is actually true. In many cases, those areas are land protected by national and state parks and preserves, where the natural vegetation of the semi-arid landscape is allowed to exist undisturbed. For example, due east of Adelaide are Billiat Conservation Park and the semi-rectangular Murray Sunset National Park, which is across the border from South Australia in Victoria. South of those parks are the parks of the Big Desert (top) and Little Desert (bottom).

  14. Spencer Cohomology and 11-Dimensional Supergravity

    NASA Astrophysics Data System (ADS)

    Figueroa-O'Farrill, José; Santi, Andrea

    2016-06-01

    We recover the classification of the maximally supersymmetric bosonic backgrounds of 11-dimensional supergravity by Lie algebraic means. We classify all filtered deformations of the Z-graded subalgebras h=h_{-2} oplus {h}_{-1} oplus{h}0} of the Poincaré superalgebra {{g}={g}_{-2} oplus{g}_{-1} oplus{g}0=Voplus Soplus {so}(V)} which differ only in zero degree, that is {{h}_0subset{g}_0} and {{h}_{j}={g}_{j}} for {{j}<0} . Aside from the Poincaré superalgebra itself and its {{{Z}}} -graded subalgebras, there are only three other Lie superalgebras, which are the symmetry superalgebras of the non-flat maximally supersymmetric backgrounds. In passing we identify the gravitino variation with (a component of) a Spencer cocycle.

  16. Straight talk with...James Ironside. [Interviewed by Jon Evans].

    PubMed

    Ironside, James

    2009-08-01

    Would you entrust your brain to a bank? Well, many people do after they die, and such brain banks-often funded by government agencies or disease charities-are essential for neuroscience research. They collect and store the healthy and diseased brain specimens that neuroscientists need to explore neurological disorders such as Alzheimer's disease, schizophrenia and autism. Each brain bank typically has a limited supply of samples and tends to operate fairly independently. This means that researchers often have to trawl through numerous brain banks to find their desired specimens. Furthermore, there is a general shortage of brain samples. To help resolve these issues in the UK, James Ironside, professor of clinical neuropathology at the University of Edinburgh, was appointed in June as the director of the new UK Brain Banks Network. An expert in human prion diseases, particularly Creutzfeldt-Jakob disease (CJD), Ironside knows all about brain banks. He established the Brain and Tissue Bank at the UK's National CJD Surveillance Unit and is involved in the Sudden Death Brain and Tissue Bank at the University of Edinburgh. Jon Evans recently caught up with Ironside to discuss his new leadership position and how the brain network will benefit neuroscience research.

  3. Lithofacies of Spencer Formation, western Tualatin Valley, Oregon

    Van Atta, R.O.

    1986-04-01

    The Spencer Formation crops out in a narrow band that trends north-northwest on the western edge of the Willamette and Tualatin Valleys, Oregon. It apparently conformably overlies mud rocks of either the Yamhill or the Nestucca Formation and is conformably overlain by the Pittsburgh Bluff Formation. The Spencer Formation consists of two members (informal): a lower highly micaceous sandstone (800-1000 ft) and an upper member that is micaceous siltstone and mudstone (1000-1300 ft). The lower member includes an upper part that is light-gray to creamy-gray, silty to muddy, pebbly lithic arkose to feldspathic litharenite, with minor arkose. Sorting is poor and beds may be laminated to ripple cross-laminated or massive and bioturbated with abundant mollusk shells, carbonized wood, and burrows. The lower part of the lower member is medium-gray to greenish-gray, silty, pumiceous lithic arkose to feldspathic litharenite. The texture tends to be more uniform and better sorted than that of the upper part of the member. Bedding is commonly massive due to bioturbation. The upper member is medium to dark-gray mudstone with thin pebble-conglomerate lenses. It intertongues with the lower member. Bioturbation, burrows, and carbonized wood are common. The trend in depositional environments appears to be from outer to mid-neritic (lower part, lower member) to shallow neritic, nearshore, and lagoonal (upper part, lower member, and upper member). The provenance of the Spencer Formation includes both proximal volcanics and distant plutonic and high-grade metamorphics.

  11. The "History" of Victorian Scientific Naturalism: Huxley, Spencer and the "End" of natural history.

    PubMed

    Lightman, Bernard

    2016-08-01

    As part of their defence of evolutionary theory, T. H. Huxley and Herbert Spencer argued that natural history was no longer a legitimate scientific discipline. They outlined a secularized concept of life from biology to argue for the validity of naturalism. Despite their support for naturalism, they offered two different responses to the decline of natural history. Whereas Huxley emphasized the creation of a biological discipline, and all that that entailed, Spencer was more concerned with constructing an entire intellectual system based on the idea of evolution. In effect, Spencer wanted to create a new scientific worldview based on evolutionary theory. This had consequences for their understanding of human history, especially of how science had evolved through the ages. It affected their conceptions of human agency, contingency, and directionality in history. Examining Huxley's and Spencer's responses to the "end" of natural history reveals some of the deep divisions within scientific naturalism and the inherent problems of naturalism in general. Whereas Huxley chose to separate the natural and the historical, Spencer opted to fuse them into a single system. PMID:26751794

    Finding an evolutionary explanation for the origins of music serves as a rich test of broader ideas on the emergence of mind and the evolution of mental processes. Charles Darwin and Herbert Spencer both offered evolutionary explanations for the origins of music, indicating the importance of the question for these two leading nineteenth-century students of "descent with modification." Their discussion unfolded between the publication of Spencer's "The origin and function of music" in 1857 and Darwin's commentaries on music in The Descent of Man in 1871 with an addendum Spencer offered to his original article in light of Darwin's views. They had conflicting views on the lines of causation, asked differing questions, and had fundamentally different approaches. Their exchange laid the foundation for the discussion among contemporary adaptationists and nonadaptationists and contributed to the thinking of those who argue for Mixed Origins of Music or that it is a Transformative Technology of Mind.

  2. A theoretical re-examination of Spencer-Attix cavity theory.

    PubMed

    Bouchard, Hugo

    2012-06-01

    The aim of radiation dosimetry is to evaluate, under specific conditions, absorbed dose in a medium of interest using a detection device. In comparison to what is meant to be evaluated, the distinctive composition of the detector causes particle fluence perturbation and shifted absorbed-dose response, both effects depending on beam quality. For electron and megavoltage photon beams, Spencer-Attix cavity theory further adapted by Nahum remains the accepted standard method used to convert absorbed dose in a wall-less detector to absorbed dose in the medium of interest. For several decades, the approach has been widely used in protocols to generate data for ionization chamber dosimetry. As a considerable effort was made towards accurate Monte Carlo methods, computation techniques are nowadays available to determine absorbed dose accurately in complex geometries, including radiation detectors. In the development of nonstandard beam protocols, direct Monte Carlo dose calculations using realistic models are being suggested and used to generate data for ionization chamber dosimetry. This indicates that for a general dosimetric context, including nonstandard beams, a more general cavity theory in agreement with what is currently being done could be adopted. Not only this could be of interest in the dosimetry standards community, but also for educational purposes. This paper re-examines Spencer-Attix theory from first principles, using a new general cavity theory rigorously derived from radiation transport equations. The approach is based on the same schematization as for Spencer-Attix's (i.e. groups of slow and fast electrons) and yields a general expression of absorbed dose for suitably implemented Monte Carlo methods. The Spencer-Attix-Nahum formulation is shown to be a special case of the presented model, outlining specific issues of the standard method. By providing an expression of absorbed dose which reflects the gold standard calculation method (i.e. Monte Carlo

We compute the effective action in this theory and find that its consistency with the world-sheet conformal invariance requires necessarily the Kodaira-Spencer equations to be satisfied by target-space Beltrami differentials. We discuss the symmetries of the theory and its reformulation in terms of the vielbein background fields.

  4. A theoretical re-examination of Spencer-Attix cavity theory

    The aim of radiation dosimetry is to evaluate, under specific conditions, absorbed dose in a medium of interest using a detection device. In comparison to what is meant to be evaluated, the distinctive composition of the detector causes particle fluence perturbation and shifted absorbed-dose response, both effects depending on beam quality. For electron and megavoltage photon beams, Spencer-Attix cavity theory further adapted by Nahum remains the accepted standard method used to convert absorbed dose in a wall-less detector to absorbed dose in the medium of interest. For several decades, the approach has been widely used in protocols to generate data for ionization chamber dosimetry. As a considerable effort was made towards accurate Monte Carlo methods, computation techniques are nowadays available to determine absorbed dose accurately in complex geometries, including radiation detectors. In the development of nonstandard beam protocols, direct Monte Carlo dose calculations using realistic models are being suggested and used to generate data for ionization chamber dosimetry. This indicates that for a general dosimetric context, including nonstandard beams, a more general cavity theory in agreement with what is currently being done could be adopted. Not only this could be of interest in the dosimetry standards community, but also for educational purposes. This paper re-examines Spencer-Attix theory from first principles, using a new general cavity theory rigorously derived from radiation transport equations. The approach is based on the same schematization as for Spencer-Attix’s (i.e. groups of slow and fast electrons) and yields a general expression of absorbed dose for suitably implemented Monte Carlo methods. The Spencer-Attix-Nahum formulation is shown to be a special case of the presented model, outlining specific issues of the standard method. By providing an expression of absorbed dose which reflects the gold standard calculation method (i.e. Monte Carlo

    Digital flood-inundation maps for a 5.3-mile reach of the White River at Spencer, Indiana, were created by the U.S. Geological Survey (USGS) in cooperation with the Indiana Office of Community and Rural Affairs. The inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science Web site at http://water.usgs.gov/osw/flood_inundation/, depict estimates of the areal extent and depth of flooding corresponding to selected water levels (stages) at the USGS streamgage White River at Spencer, Indiana (sta. no. 03357000). Current conditions for estimating near-real-time areas of inundation using USGS streamgage information may be obtained on the Internet at http://waterdata.usgs.gov/. National Weather Service (NWS)-forecasted peak-stage inforamation may be used in conjunction with the maps developed in this study to show predicted areas of flood inundation. In this study, flood profiles were computed for the stream reach by means of a one-dimensional step-backwater model. The model was calibrated by using the most current stage-discharge relation at the White River at Spencer, Indiana, streamgage and documented high-water marks from the flood of June 8, 2008. The hydraulic model was then used to compute 20 water-surface profiles for flood stages at 1-foot intervals referenced to the streamgage datum and ranging from the NWS action stage (9 feet) to the highest rated stage (28 feet) at the streamgage. The simulated water-surface profiles were then combined with a geographic information system digital elevation model (derived from Light Detection and Ranging (LiDAR) data) in order to delineate the area flooded at each water level. The availability of these maps along with Internet information regarding the current stage from the Spencer USGS streamgage and forecasted stream stages from the NWS will provide emergency management personnel and residents with information that is critical for flood response activities, such as evacuations and road

    The first-order bosonic string theory, perturbed by primary operator, corresponding to the deformation of target-space complex structure is considered. We compute the correlation functions in this theory and study their divergencies. It is found, that consistency of these correlation functions with the world-sheet conformal invariance requires the Kodaira-Spencer equations to be satisfied by target-space Beltrami differentials. This statement is checked explicitly for the three-point and four-point correlators, containing one probe operator. We discuss the origin of these divergences and their relation with beta-functions or effective action and polyvertex structures in BRST approach.

  7. Comparative petrology of arkosic sandstone lithofacies of Cowlitz, Spencer, and Yamhill Formations, northwest Oregon

    Recent discovery (1979) and commercial production of natural gas in arkosic sandstone (Clark and Wilson sand, informal) of the Cowlitz Formation near Mist, Oregon, has stimulated interest in the sedimentology and stratigraphy of Narizian sandstones of northwestern Oregon and the Willamette lowlands. Petrographic study of arkosic sandstone in the lower part of the Cowlitz Formation in surface outcrops in Clatsop, Tillamook, and Columbia Counties, Oregon, and in the Texaco 1 Clatskanie well reveals that the composition is more lithic than that of arkosic sandstone (Clark and Wilson sand) in the upper part of the Cowlitz Formation. The petrography of highly permeable, arkosic sandstone in the Spencer Formation in the western Tualatin Valley south of the Mist gas field is identical in framework grain composition, texture, matrix composition, and heavy mineral content to that of the gas producing Clark and Wilson sand. The petrography of sandstone in the Yamhill Formation in the western Tualatin Valley is very like that of sandstone in the lower part of the Cowlitz Formation of northern northwest Oregon. Diagenetic alteration is more pronounced in arkosic sandstone in the lower part of the Cowlitz Formation and in the Yamhill Formation compared to diagenesis, which is almost nil in arkosic sandstone in the upper part of the cowlitz and in the Spencer Formations. Natural gas exploration will be aided by a clearer and more certain understanding of these petrologic differences between Eocene sandstones in northwestern Oregon.

    2006-07-01

    Herbert Spencer's Principles of Psychology (1855, first edition) was regarded by his contemporaries, including William James and John Dewey, as a major contribution to what was then a very new discipline. In this book he first expounded his ideas about both evolution of species and how behavior of the individual organism adapts through interaction with the environment. His formulation of the principle that behavior changes in adaptation to the environment is closely related to the version of the law of effect propounded some years later by Thorndike. He can thus be seen as the first proponent of selectionism, a key tenet of behavior analysis. He also explicitly attacked the then prevailing view of free will as being incompatible with the biologically grounded view of psychological processes that he was advocating, and thus put forward ideas that were precursors of B. F. Skinner's in this important area of debate. PMID:16903496

    The Tennessee Department of Transportation has constructed a new bridge and approaches on State Route 30 over Cane Creek near Spencer, Tennessee. The old bridge and its approaches were fairly low, permitting considerable flow over the road during high floods. The new bridge and its approaches are considerably higher, causing different flow conditions at the site. Analysis of the effects of the new bridge, as compared to the old bridge, on floods of the magnitude of the May 27, 1973, flood is presented. The May 27, 1973, flood was greater than a 100-year flood. Analysis of the 50- and 100-year floods for the new bridge are also presented. Results of the study indicate that the new construction will increase the water-surface elevation for a flood equal to the May 27, 1973, flood by approximately 1 foot upstream from bridge. (USGS)

    The significance of Herbert Spencer's evolutionary philosophy has been generally recognized for over a century, as the familiarity of his phrase "survival of the fittest" indicates, yet accounts of the origins of his system still tend to follow too closely his own description, written many decades later. This essay argues that Spencer's own interpretation of his intellectual development gives an inadequate impression of the debt he owed to provincial scientific culture and its institutions. Most important, it shows that his evolutionism was originally stimulated by his association with the Derby philosophical community, for it was through this group--of which his father, who also appears to have espoused a deistic evolutionary theory, was a member--that he was first exposed to progressive Englightenment social and educational philosophies and to the evolutionary worldview of Erasmus Darwin, the first president of the Derby Philosophical Society. Darwin's scheme was the first to incorporate biological evolution, associationist psychology, evolutionary geology, and cosmological developmentalism. Spencer's own implicit denials of the link with Darwin are shown to be implausible in the face of Darwin's continuing influence on the Derby savants, the product of insecurity in his later years when he feared for his reputation as Lamarckism became increasingly untenable.

    The word 'environment' has a history. Before the mid-nineteenth century, the idea of a singular, abstract entity--the organism--interacting with another singular, abstract entity--the environment--was virtually unknown. In this paper I trace how the idea of a plurality of external conditions or circumstances was replaced by the idea of a singular environment. The central figure behind this shift, at least in Anglo-American intellectual life, was the philosopher Herbert Spencer. I examine Spencer's work from 1840 to 1855, demonstrating that he was exposed to a variety of discussions of the 'force of circumstances' in this period, and was decisively influenced by the ideas of Auguste Comte in the years preceding the publication of Principles of psychology (1855). It is this latter work that popularized the word 'environment' and the corresponding idea of organism--environment interaction--an idea with important metaphysical and methodological implications. Spencer introduced into the English-speaking world one of our most enduring dichotomies: organism and environment.

  16. Anomalous Geologic Setting of the Spencer-High Point Volcanic Field, Eastern Snake River Plain, Idaho

    2006-12-01

    The Spencer-High Point (SHP) volcanic field comprises an ~1700 sq km mafic volcanic rift zone located near Yellowstone in the eastern Snake River Plain (ESRP). SHP lava flows are both similar to and distinct from typical olivine tholeiite lavas of the ESRP. SHP has unique physical volcanic features characterized by numerous cinder cones and short lava flows; whereas, spatter ramparts, fissures and longer flows dominate in other ESRP regions. Topography and aerial photos indicate that vents are generally aligned northwest- southeast, which is sub-parallel to adjacent Basin and Range faults in much of the ESRP. Yet individual vents and other structural elements in SHP where Basin and Range, ESRP and thrust-faulted mountain belts all intersect, are elongated in a more east-west direction. Distinct structural control is manifested in an overall southward slope over the entire volcanic field. Short lava flows tend to flow north or south off of a central topographically higher zone of overlapping lava flows and smaller vents. Several smaller vents appear to be parasitic cones adjacent to larger eruptive centers. Contrary to these relations, preliminary geochemical data by Leeman (1982) and Kuntz et al. (1992) suggest SHP lavas are typical ESRP olivine tholeiite basalts, which notably have coarsely diktytaxitic texture. The central and eastern sections of the SHP field contain lavas with large (3-8cm), clear, euhedral plagioclase phenocrysts but without diktytaxitic texture. Lava flows in the central and eastern sections of SHP volcanic field are pahoehoe. These also contain crustal xenoliths implying a prolonged crustal history. Geochemical whole rock and microprobe analyses are currently being processed for petrogenetic history.

  17. Neoglacial fluctuations of terrestrial, tidewater, and calving lacustrine glaciers, Blackstone-Spencer Ice Complex, Kenai Mountains, Alaska

    1997-12-01

    The glaciers surrounding the Blackstone-Spencer Ice Complex display a variety of termini types: Tebenkov, Spencer, Bartlett, Skookum, Trail, Burns, Shakespeare, Marquette, Lawrence, and Ripon glaciers end in terrestrial margins; Blackstone and Beloit glaciers have tidewater termini; and Portage Glacier has a calving lacustrine margin. In addition, steep temperature and precipitation gradients exist across the ice complex from the maritime environment of Prince William Sound to the colder, drier interior. The Neoglacial history of Tebenkov Glacier, as based on overrun trees near the terminus, shows advances ca. 250- 430 AD (calibrated date), ca. 1215-1275 AD (calibrated date), and ca. 1320-1430 AD (tree ring evidence), all intervals of glacier advance around the Gulf of Alaska. However, two tidewater glaciers in Blackstone Bay retreated from their outermost moraines by 1350 AD, apparently asynchronously with respect to the regional climate signal. The most extensive Kenai Mountain glacier expansions during Neoglaciation occurred in the late Little Ice Age. The outermost moraines are adjacent to mature forest stands and bog peats that yield dates as old as 5,600 BP. Prince William Sound glaciers advanced during two Little Ice Age cold periods, 1380-1680 and 1830-1900 AD. The terrestrial glaciers around the Blackstone-Spencer Ice Complex all built moraines during the 19th century and began retreating between 1875 and 1900 AD. Portage and Burns glaciers began retreating between 1790 and 1810 AD, but their margins remained close to the outermost moraines during the 19th century. Regional glacier fluctuations are broadly synchronous in the Gulf of Alaska region. With the exception of the two tidewater glaciers in Blackstone Bay, all glaciers in the Kenai Mountains, no matter their sizes, altitudes, orientations, or types of margins, retreated at the end of the Little Ice Age. The climate signal, especially temperature, appears to be the strongest control on glacier

    This article presents the results of research on the Cd2+ ions sorption from model aqueous solutions on sunflower hulls, walnut shells and plum stones. The effect of various factors, such as mass of the natural sorbent, the pH, the time and the temperature was studied. The process of Cd2+ ions sorption on studied sorbents was described by the Langmuir model. The best sorption capacity has been achieved for sunflower hulls. The maximum sorption capacity for this material was 19.93 mg/g. W artykule przedstawiono wyniki badań, które dotyczyły usuwania jonów Cd2+ z modelowych roztworów wodnych za pomocą odpadów organicznych, takich jak: łuski słonecznika, łupiny orzecha włoskiego i pestki śliwek. Wykazano, iż badane materiały mogą być skutecznie wykorzystywane do usuwania jonów Cd2+ z modelowych roztworów wodnych w układach jednoskładnikowych. Dla badanego zakresu stężeń i przyjętych warunków procesu sorpcji w układach jednoskładnikowych, największą wydajność sorpcji jonów Cd2+, osiągnięto dla łuszczyn słonecznika. Wyniosła ona 81,75-93,02%. Dla pozostałych materiałów sorpcja jest nieco niższa, ale również zadowalająca. W pracy podano interpretację otrzymanych wyników w oparciu o jeden z najpopularniejszych modeli izoterm adsorpcji - Langmuira, który potwierdził, iż najlepszym sorbentem jonów Cd2+, spośród badanych, są łuszczyny słonecznika. Materiał ten cechuje się największą wartością parametrów qmax i b izotermy Langmuira. W tym przypadku stała qmax, wyrażająca pojemność monowarstwy, przyjęła wartość 19,93 mg/g, a parametr b, określający powinowactwo do usuwanych jonów wynosi 0,2264 dm3/mg (Rys. 5, Tab. 1). Udowodniono również, że proces sorpcji jonów Cd2+ na badanych sorbentach organicznych zależy od masy sorbentu. Dla wszystkich materiałów stopień usunięcia jonów Cd2+ z roztworów wodnych rośnie ze wzrostem masy sorbentu, aż do uzyskania maksimum przy naważce 0,5 g (Rys. 1

    With seawater desalination expanding rapidly, it is important that ecological studies are undertaken to determine the effects of brine discharge on the marine species in the area. The abundance of giant Australian cuttlefish (Sepia apama, Gray 1849) eggs and environmental data were recorded at nine sites near Point Lowly, Spencer Gulf, South Australia, an area where the largest desalination plant in the Southern hemisphere is proposed. In addition, the effects of different concentrations of desalination brine on the growth, survival and condition of cuttlefish embryos were investigated. The primary egg-laying sites for the cuttlefish were in the vicinity of Stony Point (sites 4 and 3) and the area with the least egg abundance was on the eastern and western areas around Point Lowly (sites 9 and 7) where no eggs were found. The survival of embryos decreased with an increase in salinity, with no embryos surviving to full term in salinities greater than 50 per thousand. Mean weight and mantle length also decreased with increasing salinity. Besides elevated salinity, the brine also had increased concentrations of Ba, Ca, K, Sr and Mg relative to water near Point Lowly. Brine discharge from seawater desalination poses a potential threat to the unique spawning aggregation of the giant Australian cuttlefish, in the upper Spencer Gulf, South Australia.

    The overall effects of trawling on benthic habitats and their assemblages are dependent on the distribution and intensity of trawl effort. The benthic habitats of the Spencer Gulf prawn trawling grounds are subjected to known variable levels of trawling disturbance recorded from fisher's logbooks. These habitats have not been quantitatively investigated. The aim of the study was firstly to characterise the macro-faunal and -floral assemblages and secondly, to comparatively assess trawl impact by testing the null hypothesis of no differences between five sites exposed to different intensity of trawl effort. The distribution and abundance of benthic macro-fauna and -flora were studied at two sampling resolutions by using beam trawl sampling (˜10,000 m 2) and underwater stereophotography (˜4.5 m 2) at five sites with different levels of trawl disturbance (effort). The results showed that the Spencer Gulf prawn trawling grounds are characterised by sandy sediments with a low content of silt and clay, with the exception of one site with very fine gravel. Biomass, abundance and cover of macro-fauna and -flora were generally low throughout, but with large differences among sites. Biomass, abundance and cover were found to be negatively correlated to both trawl hours from 1994-1998 and during the period of study. ANOSIM and SIMPER analyses using biomass, abundance and percentage cover as variables showed significant differences between sites with eight species or taxonomic groups contributing more than 10% to the observed similarity within sites. The two northern sites were dominated by sponges and the bearded mussel, Trichomya hirsutus, and the southern hammer oyster, Malleus meridianus. Other species that contributed to the similarity within sites were the ascidian, Polycarpa viridis, mobile epifauna (the blue swimmer crab, Portunus pelagicus, and the western king prawn, Penaeus (Melicertus) latisulcatus) and demersal fish species (Degens leatherjacket, Thamnaconus

    It is shown that the S[sub N] Boltzmann/Spencer-Lewis equations conserve energy locally if and only if they satisfy particle balance and diamond differencing is used in path length. In contrast, the spatial differencing schemes have no bearing on the energy balance. Energy is conserved globally if it is conserved locally and the multigroup cross sections are energy conserving. Although the coupled electron-photon cross sections generated by CEPXS conserve particles and charge, they do not precisely conserve energy. It is demonstrated that these cross sections can be adjusted such that particles, charge, and energy are conserved. Finally, since a conventional negative flux fixup destroys energy balance when applied to path legend, a modified fixup scheme that does not is presented.

  6. Spencer-Attix water/medium stopping-power ratios for the dosimetry of proton pencil beams

    2013-04-01

    This paper uses Monte Carlo simulations to calculate the Spencer-Attix water/medium stopping-power ratios (sw, med) for the dosimetry of scanned proton pencil beams. It includes proton energies from 30 to 350 MeV and typical detection materials such as air (ionization chambers), radiochromic film, gadolinium oxysulfide (scintillating screens), silicon and lithium fluoride. Track-ends and particles heavier than protons were found to have a negligible effect on the water/air stopping-power ratios (sw, air), whereas the mean excitation energy values were found to carry the largest source of uncertainty. The initial energy spread of the beam was found to have a minor influence on the sw, air values in depth. The water/medium stopping-power ratios as a function of depth in water were found to be quite constant for air and radiochromic film—within 2.5%. Also, the sw, med values were found to have no clinically relevant dependence on the radial distance—except for the case of gadolinium oxysulfide and proton radiography beams. In conclusion, the most suitable detection materials for depth-dose measurements in water were found to be air and radiochromic film active layer, although a small correction is still needed to compensate for the different sw, med values between the plateau and the Bragg peak region. Also, all the detection materials studied in this work—except for gadolinium oxysulfide—were found to be suitable for lateral dose profiles and field-specific dose distribution measurements in water.

A basic model problem has been identified and based upon the results for this problem, a basic hypothesis regarding the accuracy of the computational solution of the Spencer-Lewis equation is formulated. The basic hypothesis is then tested under various systematic single complexifications of the basic model problem. The results of these tests provide the framework of the refined hypothesis presented in the concluding comments. 27 refs., 3 figs., 14 tabs.

    Cavity theory is fundamental to understanding and predicting dosimeter response. Conventional cavity theories have been shown to be consistent with one another by deriving the electron (+positron) and photon fluence spectra with the FLURZnrc user-code (EGSnrc Monte-Carlo system) in large volumes under quasi-CPE for photon beams of 1 MeV and 10 MeV in three materials (water, aluminium and copper) and then using these fluence spectra to evaluate and then inter-compare the Bragg-Gray, Spencer-Attix and 'large photon' 'cavity integrals'. The behaviour of the 'Spencer-Attix dose' (aka restricted cema), D S-A(▵), in a 1-MeV photon field in water has been investigated for a wide range of values of the cavity-size parameter ▵: D S-A(▵) decreases far below the Monte-Carlo dose (D MC) for ▵ greater than  ≈  30 keV due to secondary electrons with starting energies below ▵ not being 'counted'. We show that for a quasi-scatter-free geometry (D S-A(▵)/D MC) is closely equal to the proportion of energy transferred to Compton electrons with initial (kinetic) energies above ▵, derived from the Klein-Nishina (K-N) differential cross section. (D S-A(▵)/D MC) can be used to estimate the maximum size of a detector behaving as a Bragg-Gray cavity in a photon-irradiated medium as a function of photon-beam quality (under quasi CPE) e.g. a typical air-filled ion chamber is 'Bragg-Gray' at (monoenergetic) beam energies  ⩾260 keV.

  12. Identification of crude oil source facies in Railroad Valley, Nevada, using multivariate analysis of crude oil and hydrous pyrolysis data from the Meridian Spencer Federal 32-29 well

    Comparison of biological markers of a hydrous pyrolyzate of Mississippian-Chainman Shale from the Meridian Spencer Federal 32-29 well with two crude oils produced from the same well and crude oils produced from Trap Springs, Grant Canyon, Bacon Flats, and Eagle Springs fields indicate the possibility of three distinct crude oil source facies within Railroad Valley, Nevada. The two crude oil samples produced in the Meridian Spencer Federal 32-29 well are from the Eocene Sheep Pass Formation (MSF-SP) at 10,570 ft and the Joana Limestone (MSF-J) at 13,943 ft; the pyrolyzate is from the Chainman Shale at 10,700 ft. The Chainman Shale pyrolyzate has a similar composition to oils produced in Trap Springs and Grant Canyon fields. Applying multivariate statistical analysis to biological marker data shows that the Chainman Shale is a possible source for oil produced at Trap Springs because of the similarities between Trap Springs oils and the Chainman Shale pyrolyzate. It is also apparent that MSF-SP and oils produced in the Eagle Springs field have been generated from a different source (probably the Sheep Pass Formation) because of the presence of gammacerane (C{sub 30}). MSF-J and Bacon Flats appear to be either sourced from a pre-Mississippian unit or from a different facies within the Chainman Shale because of the apparent differences between MSF-J and Chainman Shale pyrolyzate.

Hydrologic data for the study area were obtained from published and unpublished reports, maps, aerial photographs, personal interviews with residents in the area of the hypothetical mine site, and discussions with experts in the field. Where data were unavailable, "synthetic" data were generated by extrapolation from proximate or similar watersheds and (or) by assumptions based on experience or theory. Some field data were collected to corroborate and augment information originating from all these sources.

  4. Holomorphic Chern-Simons theory coupled to off-shell Kodaira-Spencer gravity

    NASA Astrophysics Data System (ADS)

    Giusto, Stefano; Imbimbo, Camillo; Rosa, Dario

    2012-10-01

    We construct an action for holomorphic Chern-Simons theory that couples the gauge field to off-shell gravitational backgrounds, comprising the complex structure and the (3,0)-form of the target space. Gauge invariance of the off-shell action is achieved by enlarging the field space to include an appropriate system of Lagrange multipliers, ghost and ghost-for-ghost fields. Both the BRST transformations and the BV action are compactly and neatly written in terms of superfields which include fields, backgrounds and their antifields. We show that the anti-holomorphic target space derivative can be written as a BRST-commutator on a functional space containing the anti-fields of both the dynamical fields and the gravitational backgrounds. We derive from this result a Ward identity that determines the anti-holomorphic dependence of physical correlators.

    1987-04-01

    Embryos of Sminthopsis crassicaudata and Sminthopsis macroura were cultured for up to 96 hours during cleavage and early expansion of the blastocyst in Dulbecco's modified Eagle's medium (DMEG), DMEG containing 2.76 gm/liter sodium lactate (DMEGL), DMEG containing 3.5 gm/liter galactose (DMEGAL), DMEG containing 15 ng/ml progesterone (DMEGP) or 150 ng/ml progesterone (DMEGP10), and DMEGL containing 15 ng/ml progesterone (DMEGLP). The disappearance of sperm was used to indicate the time of ovulation (day 0). Fertilized eggs were found in the uterus at the end of day 1, four-cell stages at the end of day 2, and embryos completing the fourth division by the end of day 3 in S. macroura and day 4 in S. crassicaudata. Estimated developmental times in culture were similar to those obtained in vivo. In both species, the first two divisions take about 24 hours, cleavage is arrested for 24 hours or longer at the rounded four-cell stage, and the third and fourth divisions take a further 24 hours. The blastocyst expands during the next 24 hours in which time the fifth and sixth divisions occur. It was possible to culture embryos from S. macroura but not S. crassicaudata over the four-cell stage to early expanding blastocysts. DMEGAL did not support cleavage in culture. DMEG, DMEGL, DMEGP, DMEGP10, and DMEGLP all supported culture during cleavage and early blastocyst expansion. Blastocyst expansion was slightly enhanced using media containing sodium lactate. More embryos completed the fifth division and formed expanding blastocysts in DMEG, DMEGL, and DMEGLP.

    2003-12-01

    The United States Deep Submergence Facility is in the process of obtaining support for construction of a new manned submersible as a replacement for DSV Alvin. A new 6000+ meter manned submersible will provide U.S. scientists with access to an additional 35 per cent of the ocean floor including some currently unreachable portions of the U.S. EEZ. Researchers will have a vehicle designed for the missions currently conducted and those of the foreseeable future having the power and endurance to maximize the usefulness of available research time. They will have a more comfortable vehicle with a larger interior, improved viewport placement, greater battery capacity, and generally better able to handle the burgeoning scientific equipment requirements. Lastly they will have a vehicle that builds on the experience and improvements of 35 years that have made ALVIN the most successful research submersible in the world. The adaptability of the National Deep Submergence Facility (NDSF) to a wide variety of science needs is its strength, but this complexity can also confuse and intimidate new users. The NDSF maintains strong science liaison services and provides potential users with assistance throughout the process of cruise planning, proposal preparation, and execution of field programs. Procedures for gaining access to these vehicles are not difficult and potential users are assisted both directly by the NDSF personnel and also through a user group of scientists dedicated to providing the benefit of their experience. A successful mechanism for obtaining feedback between users and operator has been established through the Deep Submergence Science Committee (a UNOLS oversight committee) and the science community. Programs are selected for funding on a competitive basis through various federal funding agencies by standard agency review processes. DSV ALVIN and its support ship R/V ATLANTIS are owned by the U.S. Navy and operated under charter agreement with the Office of Naval Research. Operation of the NDSF remotely operated vehicle (ROV) assets can be arranged in a fly-away mode on appropriate vessels within the UNOLS fleet or on commercial vessels or foreign research vessels provided they are suitably equipped. Scheduling of the R/V ATLANTIS is arranged through UNOLS, as is the use of the ROVs on UNOLS ships. Coordination between funding agencies and the UNOLS scheduling process strives to provide the users with the optimal scheduling of the assets in a given year. Requests for at-sea use of these assets remain strong for the foreseeable future.

  14. Effects of metals and sediment particle size on the species composition of the epifauna of Pinna bicolor near a lead smelter, Spencer Gulf, South Australia

    NASA Astrophysics Data System (ADS)

    Ward, Trevor J.; Young, Peter C.

    1984-01-01

    Pinna bicolor (Mollusca: Pelecypoda) were transplanted between four sites near a lead smelter. The species composition of their epifauna (sessile and mobile) was examined in relation to characteristics of both sediments and seston at the sites. Seventy-two taxa were distinguished in the epifaunal community. Substantial differences were found in the short-term sensitivity of some of the species to concentrations of Cd, Pb and Zn in sediments and to sediment particle size. The short-term sensitivity of many species to metals or sediment particle size explained their long-term distribution pattern. Twenty-three taxa were identified as significantly characterizing the faunal differences. Of these, eleven (four molluscs, four bryozoans, two barnacles and one ascidian) were affected by both sediment metal concentration and particle size, and eight (four molluscs, one bryozoan, one polychaete, one hydroid and one barnacle) were affected by metal contamination but not particle size. Of all fauna examined, the Bryozoa were the most metal-sensitive. Four species, Smittina raigii (Bryozoa), Galeolaria sp. 1 (Polychaeta), Epopella simplex (Cirripedia) and Monia ione (Pelecypoda) were identified by their short- and long-term sensitivity to metal contamination, and absence of sensitivity to sediment particle size, as suitable species for monitoring the effects of metal contamination on the epifauna. The implications of the results for toxicity-testing are discussed.

    2013-08-01

    Jon Driver's scientific work was characterized by an innovative combination of new methods for studying mental processes in the human brain in an integrative manner. In our collaborative work, he applied this approach to the study of attention and awareness, and their relationship to neural activity in the human brain. Here I review Jon's scientific work that relates to the neural basis of human consciousness, relating our collaborative work to a broader scientific context. I seek to show how his insights led to a deeper understanding of the causal connections between distant brain structures that are now believed to characterize the neural underpinnings of human consciousness.

  10. The 1999 Crafoord Prize lectures. Neo-Lamarckian experimentalism in America: origins and consequences.

    PubMed

    Cook, G M

    1999-12-01

    The 1890s and the first decades of the twentieth century saw a vigorous debate about the mechanisms of evolutionary change. On one side, August Weismann defended the selectionist hypothesis; on the other, Herbert Spencer defended neo-Lamarckian theory. Supporters of Spencer, notably the American paleontologist and evolutionary theorist Henry Fairfield Osborn, recognized that the questions raised by Weismann and Spencer could only be settled experimentally. They called for the application of experimental methods, and the establishment of a new institution for the purpose of confirming the inheritance of acquired characters. To a great extent, the experimental program championed by Osborn and others was implemented and, although it failed to reveal soft inheritance and was soon eclipsed by Mendelian and chromosomal genetics, it did make significant and lasting contributions to evolutionary biology. Thus the importance of methodological and institutional innovation and theoretical pluralism to the progress of science is illustrated and underscored. PMID:10672643

  11. The practice of Spencerian science: Patrick Geddes's Biosocial Program, 1876-1889.

    PubMed

    Renwick, Chris

    2009-03-01

    From the Victorian era to our own, critics of Herbert Spencer have portrayed his science-based philosophical system as irrelevant to the concerns of practicing scientists. Yet, as a number of scholars have recently argued, an extraordinary range of reformist and experimental projects across the human and life sciences took their bearings from Spencer's work. This essay examines Spencerian science as practiced by the biologist, sociologist, and town planner Patrick Geddes (1854-1932). Through a close examination of his experimental natural history of the late 1870s and early 1880s, his wider writings on the evolutionary process in the 1880s, and his efforts later in that decade to improve the slums of Edinburgh, this essay reveals Geddes's deep, unifying, and energizing commitment to Spencer's program. Recapturing that commitment can not only help historians rethink Spencerian science as practice but also suggest ways of overcoming the dichotomy between elite ideas and practical activity that bedevils much contemporary historiography of science.

Supporters of Spencer, notably the American paleontologist and evolutionary theorist Henry Fairfield Osborn, recognized that the questions raised by Weismann and Spencer could only be settled experimentally. They called for the application of experimental methods, and the establishment of a new institution for the purpose of confirming the inheritance of acquired characters. To a great extent, the experimental program championed by Osborn and others was implemented and, although it failed to reveal soft inheritance and was soon eclipsed by Mendelian and chromosomal genetics, it did make significant and lasting contributions to evolutionary biology. Thus the importance of methodological and institutional innovation and theoretical pluralism to the progress of science is illustrated and underscored.

  9. Learning as Calling and Responding

    2014-01-01

    According to Martin Buber's philosophy of dialogue, our being-in-the-world is to be conceived of as an existential dialogue. Elsewhere, I have conceptualized the teacher-student-relation accordingly (see Jons 2008), as a matter of calling and responding. The conceptualization rests on a secularised notion of vocation, paving way for…

  20. Shaking B Mediates Synaptic Coupling between Auditory Sensory Neurons and the Giant Fiber of Drosophila melanogaster

    PubMed Central

    Bacon, Jonathan P.; Blagburn, Jonathan M.

    2016-01-01

    The Johnston’s Organ neurons (JONs) form chemical and electrical synapses onto the giant fiber neuron (GF), as part of the neuronal circuit that mediates the GF escape response in Drosophila melanogaster. The purpose of this study was to identify which of the 8 Drosophila innexins (invertebrate gap junction proteins) mediates the electrical connection at this synapse. The GF is known to express Shaking B (ShakB), specifically the ShakB(N+16) isoform only, at its output synapses in the thorax. The shakB2 mutation disrupts these GF outputs and also abolishes JON-GF synaptic transmission. However, the identity of the innexin that forms the presynaptic hemichannels in the JONs remains unknown. We used electrophysiology, immunocytochemistry and dye injection, along with presynaptically-driven RNA interference, to investigate this question. The amplitude of the compound action potential recorded in response to sound from the base of the antenna (sound-evoked potential, or SEP) was reduced by RNAi of the innexins Ogre, Inx3, Inx6 and, to a lesser extent Inx2, suggesting that they could be required in JONs for proper development, excitability, or synchronization of action potentials. The strength of the JON-GF connection itself was reduced to background levels only by RNAi of shakB, not of the other seven innexins. ShakB knockdown prevented Neurobiotin coupling between GF and JONs and removed the plaques of ShakB protein immunoreactivity that are present at the region of contact. Specific shakB RNAi lines that are predicted to target the ShakB(L) or ShakB(N) isoforms alone did not reduce the synaptic strength, implying that it is ShakB(N+16) that is required in the presynaptic neurons. Overexpression of ShakB(N+16) in JONs caused the formation of ectopic dye coupling, whereas ShakB(N) prevented it altogether, supporting this conclusion and also suggesting that gap junction proteins may have an instructive role in synaptic target choice. PMID:27043822

  13. Isoflavonoid accumulation in soybean hairy roots upon treatment with Fusarium solani.

    PubMed

    2004-01-01

    Hairy roots were initiated from two soybean [Glycine max (L.) Merr.] genotypes with different susceptibility (susceptible 'Spencer' and partially resistant 'PI567.374') to the disease sudden death syndrome (SDS) caused by the soil-borne fungal pathogen Fusarium solani f. sp. glycines (FSG) to study the role of isoflavonoids in the plant response to FSG infection. Hairy root cultures obtained by transformation with Agrobacterium rhizogenes allows normal root growth that can be visually monitored. The principal isoflavones (genistin, daidzin, glycitin and their malonyl conjugates and aglycones) and also isoflavonoid phytoalexins (coumestrol and glyceollin) were measured by HPLC in extracts of the FSG-inoculated and non-inoculated hairy roots. FSG mycelia grew more slowly on inoculated PI567.374 hairy roots than on Spencer hairy roots. The glyceollin content was higher in FSG-inoculated PI567.374 hairy roots than in Spencer hairy roots even though the glyceollin precursor, the isoflavone daidzein, was higher in Spencer. The de novo synthesis of isoflavones and glyceollin was confirmed by [(14)C]Phe incorporation into glyceollin, which was higher both in the FSG-inoculated roots and surrounding medium of the cv. PI567.374 than that of Spencer. Glyceollin was the most inhibitory to FSG growth among eight isoflavonoids tested. The levels of coumestrol, a putative phytoalexin, did not change upon FSG inoculation. The defense response was also elicited by FSG culture filtrates in hairy roots grown in liquid culture. The data obtained indicate that the ability of soybean roots to rapidly produce sufficient amounts of glyceollin in response to FSG infection might be important in providing partial resistance to this fungus.

    Polarized protons are injected into the Relativistic Heavy Jon Collider (RHIC) just above transition energy. When installation of a cold partial Siberian snake in the AGS required lowering the injection energy by {Delta}{gamma} = 0.56, the transition energy in RHIC had to be lowered accordingly to ensure proper longitudinal matching. This paper presents lattice modifications implemented to lower the transition energy by {Delta}{gamma}{sub t} = 0.8.

  20. Item-location binding in working memory: is it hippocampus-dependent?

    PubMed

    Allen, Richard J; Vargha-Khadem, Faraneh; Baddeley, Alan D

    2014-07-01

    A general consensus is emerging that the hippocampus has an important and active role in the creation of new long-term memory representations of associations or bindings between elements. However, it is less clear whether this contribution can be extended to the creation of temporary bound representations in working memory, involving the retention of small numbers of items over short delays. We examined this by administering a series of recognition and recall tests of working memory for colour-location binding and object-location binding to a patient with highly selective hippocampal damage (Jon), and groups of control participants. Jon achieved high levels of accuracy in all working memory tests of recognition and recall binding across retention intervals of up to 10s. In contrast, Jon performed at chance on an unexpected delayed test of the same object-location binding information. These findings indicate a clear dissociation between working memory and long-term memory, with no evidence for a critical hippocampal contribution to item-location binding in working memory.

  1. Impaired memory for scenes but not faces in developmental hippocampal amnesia: a case study.

    PubMed

    Bird, Chris M; Vargha-Khadem, Faraneh; Burgess, Neil

    2008-03-01

    Item recognition for unfamiliar faces and scenes was tested in Jon, who has developmental amnesia resulting from bilateral hippocampal pathology. Performance and confidence judgements in healthy adults showed that both tests were equated for difficulty and had similar receiver operating characteristics (ROCs). Jon's performance on the faces test was indistinguishable from the controls, in both sensitivity and the shape of the ROC curve. In contrast his performance on the scenes test was markedly poor, and his ROC was inconsistent with both a standard dual process (DP; recollection and familiarity) model and an unequal variance signal detection model of recognition memory. Jon's data were as well fitted as controls' data by a DP model that included two recollection parameters, but required counter-intuitive parameter values corresponding to normal recollection and impaired familiarity, which likely reflect an idiosyncratic use of confidence judgements when his memory for the material is weak. The results highlight a limitation in using ROCs to estimate recollection and familiarity in patients who may have developed compensatory strategies for material that they have difficulty remembering (scenes, but not faces in this case). Overall, these data are difficult to reconcile with domain-general accounts of the hippocampal role in memory, including dual process models and the declarative model. Instead, the data indicate that the hippocampus plays a preferential role in the processing of topographical memoranda over faces memoranda.

  2. Engrailed Alters the Specificity of Synaptic Connections of Drosophila Auditory Neurons with the Giant Fiber

    PubMed Central

    Pézier, Adeline; Jezzini, Sami H.; Marie, Bruno

    2014-01-01

    We show that a subset of sound-detecting Johnston's Organ neurons (JONs) in Drosophila melanogaster, which express the transcription factors Engrailed (En) and Invected (Inv), form mixed electrical and chemical synaptic inputs onto the giant fiber (GF) dendrite. These synaptic connections are detected by trans-synaptic Neurobiotin (NB) transfer and by colocalization of Bruchpilot-short puncta. We then show that misexpressing En postmitotically in a second subset of sound-responsive JONs causes them to form ectopic electrical and chemical synapses with the GF, in turn causing that postsynaptic neuron to redistribute its dendritic branches into the vicinity of these afferents. We also introduce a simple electrophysiological recording paradigm for quantifying the presynaptic and postsynaptic electrical activity at this synapse, by measuring the extracellular sound-evoked potentials (SEPs) from the antennal nerve while monitoring the likelihood of the GF firing an action potential in response to simultaneous subthreshold sound and voltage stimuli. Ectopic presynaptic expression of En strengthens the synaptic connection, consistent with there being more synaptic contacts formed. Finally, RNAi-mediated knockdown of En and Inv in postmitotic neurons reduces SEP amplitude but also reduces synaptic strength at the JON–GF synapse. Overall, these results suggest that En and Inv in JONs regulate both neuronal excitability and synaptic connectivity. PMID:25164665

    Call for Papers: Optical Ethernet The Journal of Optical Networking (JON) is soliciting papers for a second feature issue on Optical Ethernet. Ethernet has evolved from a LAN technology connecting desktop computers to a universal broadband network interface. It is not only the vehicle for local data connectivity but also the standard interface for next-generation network equipment such as video servers and IP telephony. High-speed Ethernet has been increasingly assuming the volume of backbone network traffic from SONET/SDH-based circuit applications. It is clear that IP has become the universal network protocol for future converged networks, and Ethernet is becoming the ubiquitous link layer for connectivity. Network operators have been offering Ethernet services for several years. Problems and new requirements in Ethernet service offerings have been captured through previous experience. New study groups and standards bodies have been formed to address these problems. This feature issue aims at reviewing and updating the new developments and R&D efforts of high-speed Ethernet in recent years, especially those related to the field of optical networking. Scope of Submission The scope of the papers includes, but is not limited to, the following: Ethernet PHY development 10-Gbit Ethernet on multimode fiber Native Ethernet transport and Ethernet on legacy networks EPON Ethernet OAM Resilient packet ring (RPR) and Ethernet QoS definition and management on Ethernet Ethernet protection switching Circuit emulation services on Ethernet Transparent LAN service development Carrier VLAN and Ethernet Ethernet MAC frame expansion Ethernet switching High-speed Ethernet applications Economic models of high-speed Ethernet services Ethernet field deployment and standard activities To submit to this special issue, follow the normal procedure for submission to JON, indicating "Optical Ethernet feature" in the "Comments" field of the online submission form.

    This article is a brief account of the personality of Hughlings Jackson, his mode of life, and his intimate friends. He grew up when worldwide developments were taking place in biological thinking. The philosopher Herbert Spencer impressed him with his exciting concept of evolution, a principle which Jackson realized was applicable to the functions and disorders of the nervous system. Jackson and Spencer corresponded over a period of at least 37 years but they were not friends, their personal qualities being very different. Revered by his colleagues, even though they may not have fully understood what he was trying to say, Jackson became a legend in his own lifetime and an inspiration to neurologists who succeeded him.

    A recent work of Spencer and Christy (1990) on precise monitoring of global temperature trends from satellites is critically examined. It is tentatively concluded in the present comment that remote sensing using satellite microwave radiometers can in fact provide a means for the monitoring of troposphere-averaged air temperature. However, for this to be successful more than one decade of data will be required to overcome the apparent inherent variability of global average air temperature. It is argued that the data set reported by Spencer and Christy should be subjected to careful review before it is interpreted as evidence of the presence or absence of global warming. In a reply, Christy provides specific responses to the commenters' objections.

    The precise relation between Kodaira-Spencer path integral and a particular wave function in seven dimensional quadratic field theory is established. The special properties of three-forms in 6d, as well as Hitchin's action functional, play an important role. The latter defines a quantum field theory similar to Polyakov's formulation of 2d gravity; the curious analogy with world-sheet action of bosonic string is also pointed out.

    To better control the "licensing" of pro-Th1 dendritic cells (DCs), Spencer and colleagues have developed a synthetic ligand-inducible chimeric receptor, iMyD88/CD40 (iMC), incorporating synergistic Toll-like receptor (TLR) and costimulatory signaling elements, permitting DC regulation in vivo within the context of an immunological synapse. This novel technology results in potent anti-cancer activity.

  18. The practice of Spencerian science: Patrick Geddes's Biosocial Program, 1876-1889.

    PubMed

    Renwick, Chris

    2009-03-01

    From the Victorian era to our own, critics of Herbert Spencer have portrayed his science-based philosophical system as irrelevant to the concerns of practicing scientists. Yet, as a number of scholars have recently argued, an extraordinary range of reformist and experimental projects across the human and life sciences took their bearings from Spencer's work. This essay examines Spencerian science as practiced by the biologist, sociologist, and town planner Patrick Geddes (1854-1932). Through a close examination of his experimental natural history of the late 1870s and early 1880s, his wider writings on the evolutionary process in the 1880s, and his efforts later in that decade to improve the slums of Edinburgh, this essay reveals Geddes's deep, unifying, and energizing commitment to Spencer's program. Recapturing that commitment can not only help historians rethink Spencerian science as practice but also suggest ways of overcoming the dichotomy between elite ideas and practical activity that bedevils much contemporary historiography of science.

    South-central Australia is home to several deserts, including the Simpson Desert, whose reddish-orange sands are seen in the upper left quadrant of this Moderate Resolution Imaging Spectroradiometer (MODIS) image from July 1, 2002. Several impermanent, salty, lakes stand whitely out against the arid terrain. The largest is North Lake Eyre, southwest of center. At bottom center, Spencer Gulf separates the triangular Eyre Peninsula from the Yorke Peninsula. The Gulf of St. Vincent separates Yorke Peninsula from the mainland. In Spencer Gulf, colorful blue-green swirls indicate the presence of a bloom of marine plants called phytoplankton, whose brightly colored photosynthetic pigments stain the water. Water quality in the Gulf is an ongoing problem for Australia, as irrigation projects have diverted the already small flow of freshwater that empties into the Gulf. Other problems include contamination with pesticides and agricultural and residential fertilizer. On both the Eyre Peninsula and in the Victoria Territory to the east of Spencer Gulf, dark-colored rectangles show the boundaries of parks and nature preserves where the natural, drought-tolerant vegetation thrives.

  20. Spatial variation in parasite abundance: evidence of geographical population structuring in southern garfish Hyporhamphus melanochir.

    Hutson, K S; Brock, E L; Steer, M A

    2011-01-01

    Southern garfish Hyporhamphus melanochir were examined for metazoan parasites from nine sites in three regions (Spencer Gulf, Gulf St Vincent and northern Kangaroo Island) in South Australia to document parasite assemblages, identify candidate species suitable for use as biological tags and investigate spatial variation in parasite abundance. Four ectoparasite and 10 endoparasite species were identified representing Cestoda, Trematoda, Monogenea, Nematoda, Acanthocephala, Copepoda and Isopoda. Lernaeenicus hemirhamphi, Micracanthorhynchina hemirhamphi, Mothocya halei and Philometra sp. were suggested for 'permanent' biological markers. Multivariate discriminant function analysis showed that most sites could be distinguished based on differences in parasite abundance. Four endoparasites (Conohelmins sp., Hysterothylacium sp., M. hemirhamphi and Philometra sp.) were most important for site characterization. Limited spatial variation in permanent endoparasite abundance among localities in northern Spencer Gulf provided evidence for a distinct northern Spencer Gulf population with little interregional mixing. In contrast, considerable spatial variation in permanent endoparasite abundance between localities sampled off Kangaroo Island implied limited local movement and suggested H. melanochir may comprise a metapopulation structure. These results largely align with recent evidence from otolith chemistry that indicates fine-scale geographical population structuring in South Australian waters. PMID:21235553

    All over Europe, the provision of healthcare services is widely considered a primary duty of the government. Universal access to medical care can be considered a basic ingredient of the so-called "European social model." But if universal access to medical care is seldom questioned, European governments-faced with expanding costs caused by an increasing demand driven by an aging population and technology-driven improvements-are contemplating the possibility of "rationing" (1) treatments, or the possibility of allowing a greater role for private suppliers. If a "multi-tier" healthcare system has long been anathema to the European leadership, guaranteeing a uniform access to state-of-the-art care seems to be well beyond the means of states suffering from persisting debt crisis. Was the failure of state-controlled "adequate" healthcare totally unpredictable? Far-sighted criticisms had been offered by two eminent thinkers in the classical liberal tradition, Herbert Spencer (1820-1903) and Friedrich A. von Hayek (1899-1992). Neither author is usually recognized as a forerunner of contemporary critics of the welfare state, and both investigated the issue of the state financing and providing health services well before (Spencer) or right after (Hayek) the establishment of national health services. With the benefit of hindsight, reading Spencer and Hayek helps us to understand how the crisis of state-supplied healthcare is not rooted in the mere progress of clinical technology, but is rather the logical consequence of the theoretical basis of the model itself. Whereas modern theorists of the welfare state tend to offer theories that are impervious to a critical appraisal of their unintended consequences-insofar as they are framed in a language of "rights"-both Hayek and Spencer understood that human systems are complex, and that unwanted effects of public policy should be taken into account.

    In the last few decades, thermal data from the Galileo and Cassini spacecraft have detected various anomalies on Jovian and Saturnian satellites, including the thermally anomalous “PacMan” regions on Mimas and Tethys and the Pwyll anomaly on Europa (Howett et al. 2011, Howett et al. 2012, Spencer et al. 1999). Yet, the peculiarities of some of these anomalies, like the weak detection of the “PacMan” anomalies on Rhea and Dione and the low thermal inertia values of the widespread anomalies on equatorial Europa, are subjects for on-going research (Howett et al. 2014, Rathbun et al. 2010). Further, analysis and review of all the data both Galileo and Cassini took of these worlds will provide information of the thermal inertia and albedos of their surfaces, perhaps highlighting potential targets of interest for future Jovian and Saturnian system missions. Many previous works have used a thermophysical model for airless planets developed by Spencer (1990). However, the Three Dimensional Volatile-Transport (VT3D) model proposed by Young (2012) is able to predict surface temperatures in significantly faster computation time, incorporating seasonal and diurnal insolation variations. This work is the first step in an ongoing investigation, which will use VT3D’s capabilities to reanalyze Galileo and Cassini data. VT3D, which has already been used to analyze volatile transport on Pluto, is validated by comparing its results to that of the Spencer thermal model. We will also present our initial results using VT3D to reanalyze the thermophysical properties of the PacMan anomaly previous discovered on Mimas by Howett et al. (2011), using temperature constraints of diurnal data from Cassini/CIRS. VT3D is expected to be an efficient tool in identifying new thermal anomalies in future Saturnian and Jovian missions.Bibliography:C.J.A. Howett et al. (2011), Icarus 216, 221.C.J.A. Howett et al.

    Systematic reviews and meta-analyses constitute one of the central pillars of evidence-based medicine. However, clinical trials are poorly reported which delays meta-analyses and consequently the translation of clinical research findings to clinical practice. We propose a Center of Excellence in Research Reporting in Neurosurgery (CERR-N) and the creation of a clinically significant computational ontology to encode Randomized Controlled Trials (RCT) studies in neurosurgery. A 128 element strong computational ontology was derived from the Trial Bank ontology by omitting classes which were not required to perform meta-analysis. Three researchers from our team tagged five randomly selected RCT's each, published in the last 5 years (2004-2008), in the Journal of Neurosurgery (JoN), Neurosurgery Journal (NJ) and Journal of Neurotrauma (JoNT). We evaluated inter and intra observer reliability for the ontology using percent agreement and kappa coefficient. The inter-observer agreement was 76.4%, 75.97% and 74.9% and intra-observer agreement was 89.8%, 80.8% and 86.56% for JoN, NJ and JoNT respectively. The inter-observer kappa coefficient was 0.60, 0.54 and 0.53 and the intra-observer kappa coefficient was 0.79, 0.82 and 0.79 for JoN, NJ and JoNT journals respectively. The high degree of inter and intra-observer agreement confirms tagging consistency in sections of a given scientific manuscript. Standardizing reporting for neurosurgery articles can be reliably achieved through the integration of a computational ontology within the context of a CERR-N. This approach holds potential for the overall improvement in the quality of reporting of RCTs in neurosurgery, ultimately streamlining the translation of clinical research findings to improvement in patient care.

    Mindfulness meditation (or simply mindfulness) is an ancient method of attention training. Arguably, developed originally by the Buddha, it has been practiced by Buddhists over 2,500 years as part of their spiritual training. The popularity in mindfulness has soared recently following its adaptation as Mindfulness-Based Stress Management by Jon Kabat-Zinn (1995). Mindfulness is often compared to hypnosis but not all assertions are accurate. This article, as a primer, delineates similarities and dissimilarities between mindfulness and hypnosis in terms of 12 specific facets, including putative neuroscientific findings. It also provides a case example that illustrates clinical integration of the two methods. PMID:27003487

    Acoustic communication in Drosophilid flies is based on the production and perception of courtship songs, which facilitate mating. Despite decades of research on courtship songs and behavior in Drosophila, central auditory responses have remained uncharacterized. In this study, we report on intracellular recordings from central neurons that innervate the Drosophila AMMC (antennal mechanosensory and motor center), the first relay for auditory information in the fly brain. These neurons produce graded-potential (non-spiking) responses to sound; we compare recordings from AMMC neurons to extracellular recordings of the receptor neuron population (Johnston’s Organ neurons or JONs). We discover that while steady-state response profiles for tonal and broadband stimuli are significantly transformed between the JON population in the antenna and AMMC neurons in the brain, transient responses to pulses present in natural stimuli (courtship song) are not. For pulse stimuli in particular, AMMC neurons simply low-pass filter the receptor population response, thus preserving low-frequency temporal features (such as the spacing of song pulses) for analysis by postsynaptic neurons. We also compare responses in two closely related Drosophila species, D. melanogaster and D. simulans, and find that pulse song responses are largely similar, despite differences in the spectral content of their songs. Our recordings inform how downstream circuits may read out behaviorally-relevant information from central neurons in the AMMC. PMID:22262877

    There are 2 basic precipitation retrieval methods using passive microwave measurements: (1) Emission-based: Based on the tendency of liquid precipitation to cause an increase in brightness temperature (BT) primarily at frequencies below 22 GHz over a radiometrically cold background, often an ocean background (e.g., Spencer et al. 1989; Adler et al. 1991; McGaughey et al. 1996); and (2) Scattering-based: Based on the tendency of precipitation-sized ice to scatter upwelling radiation, thereby reducing the measured BT over a relatively warmer (usually land) background at frequencies generally 37 GHz (e.g., Spencer et al. 1989; Smith et al. 1992; Ferraro and Marks 1995). Passive microwave measurements have also been used to detect intense convection (e.g., Spencer and Santek 1985) and for the detection of hail (e.g., Cecil 2009; Cecil and Blankenship 2012; Ferraro et al. 2014). The Global Precipitation Measurement (GPM) mission expands upon the successful Tropical Rainfall Measurement Mission program to provide global rainfall and snowfall observations every 3 hours (Hou et al. 2014). One of the instruments on board the GPM Core Observatory is the GPM Microwave Imager (GMI) which is a conically-scanning microwave radiometer with 13 channels ranging from 10-183 GHz. Goal of this study: Determine the signatures of various hydrometeor species in terms of BTs measured at frequencies used by GMI by using data collected on 3 case days (all having intense/severe convection) during the Mid-latitude Continental Convective Clouds Experiment conducted over Oklahoma in 2011.

    Telegony is a discredited genetic phenomenon that a previous male may influence the characteristics of offspring subsequently borne by the same female to another male. Although its reality was acknowledged by such authorities as Charles Darwin and Herbert Spencer, it has been met with skepticism because of a lack of understanding of the theoretical basis for telegony. With the discovery of fetal genes in mother's blood, the penetration of somatic cells by sperm, and the ability of RNA to program genome rearrangement, mechanisms might exist for telegony.

Some of our most basic ideas about neural organization were contributed by Hughlings Jackson. In the early twentieth century, Charles Sherrington combined localization with the neurone theory to create the paradigm of neurophysiological integration. Because Sherrington was educated in the Jacksonian tradition of British neurology, Sherringtonian integration contains ideas that are derived from Jackson and from Herbert Spencer. PMID:11640240

    On her way to a dreaded dental appointment to have an aching tooth pulled, Clara Spencer meets a solicitous stranger, Jim, and by the end of the story runs off with him, in many interpretations to perdition. But since 1) Shirley Jackson (who herself had much dental work and hated it) has suffered from typecasting as a horror writer, 2) dental gas anesthesia protocols of the time as Clara is anticipating could lead to sexual hallucinations, and 3) contemporary literature celebrated escapist fantasy (e.g., the invisible giant rabbit in Harvey), this article proposes instead that Jim is Clara's own imaginative, comforting, therapeutic creation.

    Whereas most scientists are highly critical of constructivism and relativism in the context of scientific knowledge acquisition, the dominant school of chemical education researchers appears to support a variety of such positions. By reference to the views of Herron, Spencer, and Bodner, I claim that these authors are philosophically confused, and that they are presenting a damaging and anti-scientific message to other unsuspecting educators. Part of the problem, as I argue, is a failure to distinguish between pedagogical constructivism regarding students' understanding of science, and constructivism about the way that scientific knowledge is acquired by expert scientists.

    The most commonly cited descriptions of the behavioral characteristics of habituation come from two papers published almost 40 years ago (Thompson and Spencer, 1966; Groves and Thompson, 1970). In August 2007, the authors of this review, who study habituation in a wide range of species and paradigms, met to discuss their work on habituation and to revisit and refine the characteristics of habituation. This review offers a re-evaluation of the characteristics of habituation in light of these discussions. We made substantial changes to only a few of the characteristics, usually to add new information and expand upon the description rather than to substantially alter the original point. PMID:18854219

    The results of measurements of saturated liquid densities using a high-pressure stainless steel pycnometer system over a wide variation of temperature from 298.15 to 473.15 K are presented for benzene, cyclohexane, and hexane. Experimental densities were compared with those predicted by the Spencer-Danner-modified Rackett equation (SDR) and the Hankinson-Brobst-Thompson correlation (HBT). The SDR showed an average deviation of 0.22% while the HBT predicted the densities of the three organic solvents with an average deviation of 0.28%. The data obtained have also been compared with the available data reported in the literature.

    Showstack, Randy

    Yucca Mountain in Nevada will be the U.S. long-term geologic repository for high-level radioactive waste, President George W. Bush announced on 15 February. Bush endorsed a formal recommendation by Department of Energy (DOE) Secretary Spencer Abraham, which followed more than 20 years of scientific study. The decision, which the state of Nevada is challenging in the U.S. Congress, allows the government's plans for the repository to proceed to the licensing phase.The plan calls for Yucca Mountain to accept a total of 84,900 metric tons of radioactive waste from temporary storage facilities at 131 sites in 39 states.

    We present the evidence for the existence of the topological string analogue of M-theory, which we call Z-theory. The corners of Z-theory moduli space correspond to the Donaldson-Thomas theory, Kodaira-Spencer theory, Gromov-Witten theory, and Donaldson-Witten theory. We discuss the relations of Z-theory with Hitchin's gravities in six and seven dimensions, and make our own proposal, involving spinor generalization of Chern-Simons theory of three-forms.

    We study the topological B-model on a deformed Z orbifolded conifold by investigating variation of complex structures via quantum Kodaira-Spencer theories. The fermionic/brane formulation together with systematic utilization of symmetries of the geometry gives rise to a free fermion realization of the amplitudes. We derive Ward identities which solve the perturbed free energy exactly. We also obtain the corresponding Kontsevich-like matrix model. All these confirm the recent conjecture on the connection of the theory with cˆ=1 type 0A string theory compactified at the radius R=√{α/2}.

    Bershadsky, M.; Sadov, V.

    In this paper we discuss the connection on a space of N = 2 TCFT's that appears in the context of background (in)dependence. We formulate a family of target space field theories with a similar connection on it. Each theory is a gauge theory (with the gauge group being S Diff in the case of three-fold). It describes deformations of Kähler structures much like Kodaira Spencer theory describes deformations of the complex structures. It is manifestly background-independent. It appears to be a target space field theory for supersymmetric quantum mechanics.

    2013-07-25

    Telegony is a discredited genetic phenomenon that a previous male may influence the characteristics of offspring subsequently borne by the same female to another male. Although its reality was acknowledged by such authorities as Charles Darwin and Herbert Spencer, it has been met with skepticism because of a lack of understanding of the theoretical basis for telegony. With the discovery of fetal genes in mother's blood, the penetration of somatic cells by sperm, and the ability of RNA to program genome rearrangement, mechanisms might exist for telegony.

    Recently a discontinuous percolation transition was reported in a new “explosive percolation” problem for irreversible systems [D. Achlioptas, R. M. D’Souza, and J. Spencer, Science 323, 1453 (2009)SCIEAS0036-807510.1126/science.1167782] in striking contrast to ordinary percolation. We consider a representative model which shows that the explosive percolation transition is actually a continuous, second order phase transition though with a uniquely small critical exponent of the percolation cluster size. We describe the unusual scaling properties of this transition and find its critical exponents and dimensions.

    The existence of explosive phase transitions in random (Erdös Rényi-type) networks has been recently documented by Achlioptas, D’Souza, and Spencer [Science 323, 1453 (2009)SCIEAS0036-807510.1126/science.1167782] via simulations. In this Letter we describe the underlying mechanism behind these first-order phase transitions and develop tools that allow us to identify (and predict) when a random network will exhibit an explosive transition. Several interesting new models displaying explosive transitions are also presented.

    On her way to a dreaded dental appointment to have an aching tooth pulled, Clara Spencer meets a solicitous stranger, Jim, and by the end of the story runs off with him, in many interpretations to perdition. But since 1) Shirley Jackson (who herself had much dental work and hated it) has suffered from typecasting as a horror writer, 2) dental gas anesthesia protocols of the time as Clara is anticipating could lead to sexual hallucinations, and 3) contemporary literature celebrated escapist fantasy (e.g., the invisible giant rabbit in Harvey), this article proposes instead that Jim is Clara's own imaginative, comforting, therapeutic creation.

    2009-08-01

    In response to the commentaries on our paper (Spencer et al., 2009) we summarize what a developmental systems perspective offers for a twenty-first century science of development by highlighting five insights from developmental systems theory. Where applicable, the discussion is grounded in a particular example-the emergence of ocular dominance columns in early development. Ocular dominance columns are a paragon of epigenesis and are inconsistent with the nativist view. We conclude with optimism that developmental science can move beyond the nativist-empiricist debate armed with both modern technological tools and strong theory to guide their use.

  17. High Availability in Optical Networks

    Call for Papers: High Availability in Optical Networks Submission Deadline: 1 January 2006 The Journal of Optical Networking (JON) is soliciting papers for a feature Issue pertaining to all aspects of reliable components and systems for optical networks and concepts, techniques, and experience leading to high availability of services provided by optical networks. Most nations now recognize that telecommunications in all its forms -- including voice, Internet, video, and so on -- are "critical infrastructure" for the society, commerce, government, and education. Yet all these services and applications are almost completely dependent on optical networks for their realization. "Always on" or apparently unbreakable communications connectivity is the expectation from most users and for some services is the actual requirement as well. Achieving the desired level of availability of services, and doing so with some elegance and efficiency, is a meritorious goal for current researchers. This requires development and use of high-reliability components and subsystems, but also concepts for active reconfiguration and capacity planning leading to high availability of service through unseen fast-acting survivability mechanisms. The feature issue is also intended to reflect some of the most important current directions and objectives in optical networking research, which include the aspects of integrated design and operation of multilevel survivability and realization of multiple Quality-of-Protection service classes. Dynamic survivable service provisioning, or batch re-provisioning is an important current theme, as well as methods that achieve high availability at far less investment in spare capacity than required by brute force service path duplication or 100% redundant rings, which is still the surprisingly prevalent practice. Papers of several types are envisioned in the feature issue, including outlook and forecasting types of treatments, optimization and analysis, new

    2005-09-01

    Call for Papers: Convergence The Journal of Optical Networking (JON) invites submissions to a special issue on Convergence. Convergence has become a popular theme in telecommunications, one that has broad implications across all segments of the industry. Continual evolution of technology and applications continues to erase lines between traditionally separate lines of business, with dramatic consequences for vendors, service providers, and consumers. Spectacular advances in all layers of optical networking-leading to abundant, dynamic, cost-effective, and reliable wide-area and local-area connections-have been essential drivers of this evolution. As services and networks continue to evolve towards some notion of convergence, the continued role of optical networks must be explored. One vision of convergence renders all information in a common packet (especially IP) format. This vision is driven by the proliferation of data services. For example, time-division multiplexed (TDM) voice becomes VoIP. Analog cable-television signals become MPEG bits streamed to digital set-top boxes. T1 or OC-N private lines migrate to Ethernet virtual private networks (VPNs). All these packets coexist peacefully within a single packet-routing methodology built on an optical transport layer that combines the flexibility and cost of data networks with telecom-grade reliability. While this vision is appealing in its simplicity and shared widely, specifics of implementation raise many challenges and differences of opinion. For example, many seek to expand the role of Ethernet in these transport networks, while massive efforts are underway to make traditional TDM networks more data friendly within an evolved but backward-compatible SDH/SONET (synchronous digital hierarchy and synchronous optical network) multiplexing hierarchy. From this common underlying theme follow many specific instantiations. Examples include the convergence at the physical, logical, and operational levels of voice and

    This article presents the results of the research on the Pb2+ ions sorption from model aqueous solutions on walnut shells, plum stones and sunflower hulls. The effect of various factors, such as the concentration of natural sorbent, the pH, and the temperature was studied. The process of Pb2+ ions sorption on studied sorbents was described by the Langmuir model. The best sorption capacity has been revealed for sunflower hulls. The maximum sorption capacity for this material was 36.9 mg/g. W artykule przedstawiono wyniki badań, które dotyczyły usuwania jonów Pb2+ z modelowych roztworów wodnych za pomocą odpadów organicznych, takich jak: łuski słonecznika, łupiny orzecha włoskiego i pestki śliwek. Dla badanego zakresu stężeń od 6,0-110 mg/dm3 i warunków procesu największą wydajność sorpcji, będącą w zakresie (89,4-96,3)% uzyskano dla łusek słonecznika. W przypadku łupin orzecha włoskiego i pestek śliwek sorpcja jonów Pb2+ jest znacznie niższa a jej wydajność wynosi odpowiednio (60,8-78,7)% i (62,3-81,3)%. Zbadano także wpływ stężenia sorbentu, pH roztworu i temperatury na badany proces sorpcji. Dla wszystkich materiałów optymalne stężenie sorbentu wyniosło 5 g/dm3. Powyżej tej wartości nie obserwowano istotnych zmian w stopniu redukcji jonów Pb2+ (rys.2). We wszystkich przypadkach maksima sorpcji osiągnięto przy pH równym 4,0±0,1 co obrazuje rysunek 3. Obniżenie sorpcji, występujące przy pH poniżej i powyżej wartości 4,0 prawdopodobnie związane jest to z ładunkiem gromadzącym się na powierzchni sorbentu (elektrostatyczne odpychanie i przyciąganie badanych jonów). Wartość pH roztworu determinuje także formę oraz stężenie badanego jonu w roztworze. W roztworach silnie kwaśnych ołów występuje głównie w postaci kationów. Stopniowy wzrost pH prowadzi do tworzenia jonów kompleksowych i strącania go w postaci wodorotlenku. Wykazano również, że ze wzrostem temperatury w zakresie (293-313)K nast

    This study presents Monte Carlo-calculated absolute and normalized (relative to a (60)Co beam) sensitivity values of silicon diode dosimeters for a variety of commercially available silicon diode dosimeters for radiotherapy photon beams in the energy range of (60)Co-24 MV. These values were obtained at 5 cm depth along the central axis of a water-equivalent phantom of 10 cm × 10 cm field size. The Monte Carlo calculations were based on the EGSnrc code system. The diode dosimeters considered in the calculations have different buildup materials such as aluminum, brass, copper, and stainless steel + epoxy. The calculated normalized sensitivity values of the diode dosimeters were then compared to previously published measured values for photon beams at (60)Co-20 MV. The comparison showed reasonable agreement for some diode dosimeters and deviations of 5-17 % (17 % for the 3.4 mm brass buildup case for a 10 MV beam) for some diode dosimeters. Larger deviations of the measurements reflect that these models of the diode dosimeter were too simple. The effect of wall materials on the absorbed dose to the diode was studied and the results are presented. Spencer-Attix and Bragg-Gray stopping power ratios (SPRs) of water-to-diode were calculated at 5 cm depth in water. The Bragg-Gray SPRs of water-to-diode compare well with Spencer-Attix SPRs for ∆ = 100 keV and above at all beam qualities.

    A collaborative effort between Washington University in St. Louis and Spencer Technologies in Seattle, WA has been undertaken to create a multimodal 3D reconstruction of the human cochlea and vestibular system. The goal of this project is to improve the accuracy of in vivo CT reconstructions of implanted cochleae, and to expand the knowledge of high-resolution anatomical detail provided by orthogonal-plane optical sectioning (OPFOS). At WUSL, computed tomography (CT) images of the cochlea are used to determine the position of cochlear implant electrodes relative to target auditory neurons. The cochlear implant position is determined using pre- and post-operative CT scans. The CT volumes are cross-registered to align the semicircular canals and internal auditory canal, which have a unique configuration in 3-D space. The head of a human body donor was scanned with a clinical CT device, after which the temporal bones were removed, fixed in formalin and trimmed prior to scanning with a laboratory Micro CT scanner. Following CT, the temporal bones were sent to the OPFOS Imaging Lab at Spencer Technologies for a further analysis. 3-D reconstructions of CT and OPFOS imaging modalities were compared, and results are presented.

    TOVS (Tiros Operational Vertical Sounder) is the suite of infra-red and microwave sounding instruments, including HIRS-2 and MSU, that have flown on the NOAA Polar orbiting operational satellites TIROS-N, NOAA 6-14 from November 1978 to the present day. Data has been analyzed for the entire time period using a consistent methodology to produce twice daily per satellite global fields of surface skin temperature, atmospheric temperature-moisture profile, cloud top pressure, and fractional cloud cover, OLR and clear sky OLR, and precipitation. All parameters were found to depend on the orbit time of observation which differed as a function of time both because of differing initial satellite orbits and orbit drift. This must be accounted for before one can attempt to find trends in the data. Methodology to account for orbit drift will be shown. Trends will then be shown, over the 21 year period 1979-1999, for surface skin temperature and atmospheric temperature profile. There has been global warming near the surface which falls off rapidly with height. Trends will also be shown for values of MSU2R and MSU4 which are computed from the soundings. These will be compared to trends of MSU2R and MSU4 observed by Spencer and Christy. There is generally good agreement between Spencer and Christy MSU2R trends and those computed from the TOVS Pathfinder data set, with the largest differences over the tropics.

  3. Transcranial power M-mode Doppler ultrasound for diagnosis of patent foramen ovale

    Moehring, Mark; Spencer, Merrill

    2005-04-01

    Patent foramen ovale (PFO) is a right-to-left shunt (RLS) which communicates blood from the right to left atrium of the heart. PFO has been associated with stroke and, more recently, with migraine headache. Diagnosis of RLS can be accomplished effectively with transcranial power M-mode Doppler ultrasound (PMD). PMD is a modality which can be performed without the sedation required by the more invasive diagnostic technique using transesophageal echocardiography. PMD for this application consists of 2 MHz pulse Doppler ultrasound with placement of sample gates at 2 mm intervals along the single-transducer beam axis, and 8 kHz pulse repetition rate (PMD100M, Spencer Technologies). Doppler power versus depth is constructed every 4ms, using 33 sample gates. Bubble microemboli injected in the venous system and moving across a PFO present as high intensity tracks on a PMD image, as emboli transit from the heart to the brain and through the observed cerebral vasculature. Use of PMD in this context has been reported in the clinical literature [M. P. Spencer, M. A. Moehring, J. Jesurum et al, J. Neuroimaging 14, 342-349 (2004)]. This talk surveys the basic technical features of PMD for sensing PFO-related showers of bubble microemboli, and how these features provide clues to the severity of PFO.

    Recompression during decompression has been suggested to possibly reduce the risk of decompression sickness (DCS). The main objective of the current study was to investigate the effects of FLIRT (First Line Intermittent Recompression Technique) on bubble detection in man. 29 divers underwent 2 simulated dives in a dry recompression chamber to a depth of 40 msw (500 kPa ambient pressure) in random order. A Buehlmann-based decompression profile served as control and was compared to an experimental profile with intermittent recompression during decompression (FLIRT). Circulating bubbles in the right ventricular outflow tract (RVOT) were monitored by Doppler ultrasound and quantified using the Spencer scoring algorithm. Heat shock protein 70 (HSP70), thrombocytes, D-Dimers and serum osmolarity were analyzed before and 120 min after the dive. Both dive profiles elicited bubbles in most subjects (range Spencer 0-4). However, no statistically significant difference was found in bubble scores between the control and the experimental dive procedure. There was no significant change in either HSP70, thrombocytes, and D-Dimers. None of the divers had clinical signs or symptoms suggestive of DCS. We conclude that FLIRT did not significantly alter the number of microbubbles and thus may not be considered superior to classical decompression in regards of preventing DCS.

    The Southern Australia Integrated Marine Observing System, or SAIMOS, is one of five nodes operating as part of the Australia-wide Integrated Marine Observing System (IMOS). This is a collaborative program designed to observe Australia's oceans, both coastal and blue-water. Since February 2008 Physical Data has been collected for SAIMOS in both summer and winter months during 8 surveys. The data collected during summer are used to characterise the nature and dynamics of the Kangaroo Island-Eyre Peninsula upwelling system during a record upwelling event in February 2008. During this event a plume of very cool water was observed along the bottom from South of KI to the Eyre Peninsula. This plume dissipated rapidly after the end of upwelling favourable winds and by March 2008 had disappeared entirely from the observations. The data are also used to study the dense high salinity outflow from Spencer Gulf observed during the winter months. The dense plume result from surface cooling of high salinity waters at the head of Spencer Gulf. One striking result of these observations is that the outflow occurs during a series of strong pulses with a period of approximately 2 weeks and duration of 1-3 days. During these pulses bottom velocities at 100 m can exceed 1 m/s.

    2002-12-01

    In this article we study the four-particle decay of the Bethe-Salpeter (B-S) kernel for the high-temperature Ising model. We use the hyperplane decoupling method [T. Spencer, Commun. Math. Phys. 44, 143 (1975); R. S. Schor, Nucl. Phys. B 222, 71 (1983)] to prove exponential decay in a set of variables particularly adapted to the methods of Spencer and Zirilli [Commun. Math. Phys. 49, 1 (1976)] for the analysis of scattering and bound states in QFT, transcribed to lattice theories by Auil and Barata [Ann. Henri Poincare 2, 1065 (2001)]. We study arbitrary derivatives of the general n-point correlation functions with respect to the interpolating variables, and we are able to obtain, in some cases, information about the third derivatives of the B-S kernel. As a later consequence, we have two-body asymptotic completeness for the (massive) Euclidean lattice field theory implemented by this model. This allows us to analyze the Ornstein-Zernike behavior of four-point functions, related to the specific heat of the model.

    We discuss multiloop maximally helicity violating amplitudes in the N=4 supersymmetric Yang-Mills theory in terms of effective gravity in the momentum space with IR regulator branes as degrees of freedom. Kinematical invariants of external particles yield the moduli spaces of complex or Kahler structures which are the playgrounds for the Kodaira-Spencer or Kahler type gravity. We suggest fermionic representation of the loop maximally helicity violating amplitudes in the N=4 supersymmetric Yang-Mills theory assuming the identification of the IR regulator branes with Kodaira-Spencer fermions in the B model and Lagrangian branes in the A model. The two-easy mass box diagram is related to the correlator of fermionic currents on the spectral curve in the B model or hyperbolic volume in the A model and it plays the role of a building block in the whole picture. The Bern-Dixon-Smirnov-like ansatz has the interpretation as the semiclassical limit of a fermionic correlator. It is argued that fermionic representation implies a kind of integrability on the moduli spaces. We conjecture the interpretation of the reggeon degrees of freedom in terms of the open strings stretched between the IR regulator branes.

The Bern-Dixon-Smirnov-like ansatz has the interpretation as the semiclassical limit of a fermionic correlator. It is argued that fermionic representation implies a kind of integrability on the moduli spaces. We conjecture the interpretation of the reggeon degrees of freedom in terms of the open strings stretched between the IR regulator branes.

  9. Nonassociative learning processes affecting swimming probability in the seaslug Tritonia diomedea: habituation, sensitization and inhibition.

    1998-10-01

    The role of nonassociative learning processes in determining whether or not a chemical stimulus will elicit the Tritonia diomedea swimming response was examined in a variety of conditioning experiments. Iterative presentation of a chemical stimulus resulted in a reduced swimming probability (SP). By the criteria of Thompson and Spencer (Thompson RF, Spencer WA. Psychol. Rev. 1966;73:16-43) and others, this iterative reduction of SP was concluded to be the result of habituation. Site-specificity and a below zero effect implicated sensory pathways in habituation memory storage. The iterative reduction in SP was reversible, confirming that a sensitization-like process can also influence SP. It was further concluded that a short-term decrement in swimming cycle number was most likely due to a constraint in the effector pathway. Experience with a tactile stimulus had a long-lasting decremental effect on SP. This heterostimic reduction of SP was amplified in a multistimic paradigm that included both chemical and tactile stimuli during training. The chemical stimuli alone did not alter SP in this experiment. Multistimic reduction lasted for a week and was reversed temporarily by an excitatory chemical stimulus. The long-lasting reduction of SP by tactile stimulation appears to be the result of a novel nonassociative inhibitory process, which was distinguished from other learning processes by its duration and specificity. A total of three distinct learning processes are postulated to account for the role of simple types of experience in determining SP in Tritonia: habituation, sensitization, and nonassociative inhibition.

  11. Bernard J. Wood Receives 2013 Harry H. Hess Medal: Citation

    NASA Astrophysics Data System (ADS)

    Hofmann, Albrecht W.

    2014-01-01

    As Harry Hess recognized over 50 years ago, mantle melting is the fundamental motor for planetary evolution and differentiation. Melting generates the major divisions of crust mantle and core. The distribution of chemical elements between solids, melts, and gaseous phases is fundamental to understanding these differentiation processes. Bernie Wood, together with Jon Blundy, has combined experimental petrology and physicochemical theory to revolutionize the understanding of the distribution of trace elements between melts and solids in the Earth. Knowledge of these distribution laws allows the reconstruction of the source compositions of the melts (deep in Earth's interior) from their abundances in volcanic rocks. Bernie's theoretical treatment relates the elastic strain of the lattice caused by the substitution of a trace element in a crystal to the ionic radius and charge of this element. This theory, and its experimental calibrations, brought order to a literature of badly scattered, rather chaotic experimental data that allowed no satisfactory quantitative modeling of melting processes in the mantle.

    Ms Trisha Meili revealed her identity as the Central Park Jogger in a presentation at Spaulding Rehabilitation Hospital in Boston in May 2003. Her co-presenter was Dr Jon Kabat-Zinn, whose teachings on mindfulness and meditation had been important in Ms Meili's rehabilitation process. This transcript of that conversation describes the various phases she underwent in her recovery, and documents the role of her self-discovered practice of mindfulness in restoring her emotional and physical functioning. Dr Kabat-Zinn reflects on the deeper meaning of the term "rehabilitation," and demonstrates its natural connections to the practice of meditation. A final question and answer section with audience members (clinicians, brain injury survivors and their families) documents the role of emotional support and inspiration in recovery from devastating injury.

    Foam spray equipment and materials for dust suppression on longwall double drum shearer faces have been procured. This equipment includes metering pumps, foam generators and mounting brackets, foam solutions, flow meters, real time and gravimetric sampling equipment, hoses and valve banks. Initial tests have been conducted in the laboratory with three types of generators and five types of foam solutions. Based on these tests, Senior Conflow's cluster spray and Onyx Chemical Company's millifoam solution have been selected. For pumping foam solution to the shearer, Jon Bean's 2 hp, 120 VAC single-phase ceramic lined piston pump has been selected. For field tests, equipment has been installed underground in Dobbin mine in Upper Freeport seam on Eickhoff EDW 300 double drum shearer. Foamspray tests have been conducted. Real time and gravimetric dust samples have been collected. Real time sampling results indicate a dust level reduction of up to 37 percent with foam spray compared to the base case of water sprays.

    Scientists surveying the Cayman Trough in the Caribbean Sea have discovered the world's deepest undersea volcanic vents, or “black smokers,” the National Oceanography Center (NOC) in Southampton, UK, announced on 11 April. The vents were found at a depth of 5000 meters, about 800 meters deeper than any previously discovered. Jon Copley, a marine biologist at the University of Southampton's School of Ocean and Earth Science, said, “Seeing the world's deepest black-smoker vents looming out of the darkness was awe-inspiring.” Geochemist Doug Connelly of NOC, principal scientist of the expedition, noted, “We hope our discovery will yield new insights into biogeochemically important elements in one of the most extreme naturally occurring environments on our planet.” Researchers used an NOC-developed Autosub6000 robot submarine, which was remotely controlled from the Royal Research Ship James Cook.

    The International Union for Conservation of Nature (IUCN) announced on 9 September that it will develop a new Red List of Ecosystems that will identify which ecosystems are vulnerable or endangered. The list, which is modeled on the group's Red List of Threatened Species™, could help to guide conservation activities and influence policy processes such as the Convention on Biological Diversity, according to the group. “We will assess the status of marine, terrestrial, freshwater, and subterranean ecosystems at local, regional, and global levels,” stated Jon Paul Rodriguez, leader of IUCN's Ecosystems Red List Thematic Group. “The assessment can then form the basis for concerted implementation action so that we can manage them sustainably if their risk of collapse is low or restore them if they are threatened and then monitor their recovery.”

  1. Physics Myth Busting: A Lab-Centered Course for Non-Science Students

    2011-10-01

    There is ongoing interest in how and what we teach in physics courses for non-science students, so-called "physics for poets" courses. Art Hobson has effectively argued that teaching science literacy should be a key ingredient in these courses. Hobson uses Jon Millers definition of science literacy, which has two components: first, "a basic knowledge of key scientific concepts," and second, "an understanding of the process of science."2 In preparing to teach our course for non-science students, I found that the majority of textbooks and courses focus on the first component. However, I wanted a lab-centered course that would give students hands-on practice doing science. I describe in this article a course I designed and implemented at Wabash College that focused on teaching students "the process of science." The course was titled "Adventures in Physics: Mythbusters" and was based loosely on the popular Discovery Channel show "MythBusters."3

    Jon Amiel, director of the 2003 science fiction blockbuster movie The Core, told a room packed with geophysicists at the recent AGU Fall Meeting that he had a confession to make. The confession had nothing to do with what he called the “preposterous premises” of the movie, including that humans could start or stop the spinning of Earth's core. Rather, he told the crowd at the Tuesday evening presentation “Science and the Cinema: AGU Sciences Meet Hollywood” about his recurring dream of being on stage wearing nothing but a skimpy T-shirt. “This dream now has come true. Here I am, I'm talking to a whole room of geophysicists about The Core. I've never felt like the T-shirt was this short,” he said.

    The stability of liquid filaments is relevant both in industrial applications, such as inkjet printing and atomization, and in nature, where the stability of filaments has a large influence on the final drop size distribution of rain droplets and waterfalls. The liquid filament may either stably collapse into a single droplet, or break up into multiple droplets. Which scenario is realized depends on the viscosity and the aspect ratio of the filament. Here we study the collapse of an axisymmetric liquid filament is analytically and with a numerical model. We find that a long, high viscous filament can only break up due to the Rayleigh-Plateau instability, whereas a low viscous filament can break up due to end-pinching. The theory shows quantitative agreement with recent experimental findings by Castréjon-Pita et al., PRL 108, 074506 (2012).

    The structure of MgO upon shock compression was interrogated at the Omega Laser at the Laboratory for Laser Energetics, University of Rochester. Laser drives of up to 2 kJ over 7 ns focused onto a polyimide ablator were used to shock compress 50- μ m thick polycrystalline or single-crystal MgO. Scattered He- α X-rays from an Fe backlighter timed with maximum compression were collected using the PXRDiP diagnostic, in which image plates line the inner walls of a box attached to the target package. Other diagnostics utilized were VISAR (velocity history) and Streaked Optical Pyrometry (temperature). We will present experiments probing the B 1 - B 2 phase transition of MgO and discuss the implications for detection of melting.

  7. The knowledge most worth having: Otis W. Caldwell (1869 1947) and the rise of the general science course

    Heffron, John M.

    1995-07-01

    In 1860 Herbert Spencer asked the famous rhetorical question ‘What Knowledge is of Most Worth?’ The unequivocal answer was science. Giving greater attention to science and scientific knowledge would not only produce additional scientists; more important, argued Spencer, it would make better parents, better church-goers, better citizens and workers, better artists and better consumers of art. It would lead to a ‘command of fundamental processes’, ‘worthy home membership’, ‘worthy use of leisure’, ‘ethical character’ — the goals of a general education spelled out by Spencerians within the National Educational Association in 1918. Here is our puzzle, then: how are we to interpret a definition of science, one widely accepted both in Spencer's time and in our own, that comes so close descriptively to a commonsensical view of what constitutes non-science? The answer to this question lies in part in the historical relationship between science and general education, a relationship established in the opening decades of this century, when the authority of science and scientific objectivity was in the minds of most educators unimpeachable. The high school general science course, developed in its early stages by the botanist and educator, Otis W. Caldwell, was a potent symbol of this new relationship. Organized around broad, topical issues and claiming to teach the mundane truths of life, general science was more than a loose collection of facts from the various earth, biological, and physical sciences. Its many advocates viewed the new unified science course as pedagogically independent of the specialties yet central to education in general. In 1949, two years after Caldwell's death, 72 percent of the total science enrollments in the United States were in general science and biology, its closest cognate. This paper examines the rise of the general science course and its implications for the reform of secondary school science education. It concludes that

  8. Substrate engineering for defect reduction and microstructure control in the growth of indium arsenide on (100) gallium arsenide

    NASA Astrophysics Data System (ADS)

    Ganesan, Suryanarayanan

    The development of devices based on InAs, GaSb, and AlSb, semiconductors that possess narrow band-gaps and 0.61 nm lattice parameters, has been limited by the defects that ensue in epitaxial films that typically are grown on commercial semi-insulating, but 7% lattice-mismatched, GaAs substrates. The studies described in this dissertation investigate the application of a lateral epitaxial overgrowth technique for defect reduction and microstructure control to the InAs/GaAs heteroepitaxial system by exploring the development of microstructure at various stages of island and film growth in conventional and lateral overgrowth epitaxy (that is, on unpatterned and mask-patterned substrates, respectively). For a range of growth conditions, InAs films on unpatterned (100) GaAs substrates exhibit not only the threading dislocations characteristic of largely mismatched epitaxial films, but also systematic tilting within micron-scale InAs domains. Alteration of the pattern and magnitude of the tilt achieved by varying the growth conditions and/or introducing mask-patterned substrates suggest that not only chemical and kinetic, but also physical constraints can direct microstructural evolution during growth. Backscattered electron Kikuchi pattern-based orientation imaging was used to investigate the origin of the improved epitaxial alignment that is realized when InAs films were grown on mask-patterned (100) GaAs substrates. The island size at coalescence was shown to be critical in determining whether a single or two-fold, four-fold or six-fold epitaxial orientation relationship(s) is (are) present in the film. The evolution of tilt with increasing island size is attributed to the particulars of the misfit dislocation network that forms, which appears to evolve in this epitaxial system as the island grows, in accordance with a model proposed by Spencer and Tersoff [1,2]. Sub-micron (˜0.5 mum or less) island sizes at coalescence appear to lead to a single orientation aligned

  9. LIDAR Helps Identify Source of 1872 Earthquake Near Chelan, Washington

    NASA Astrophysics Data System (ADS)

    2015-12-01

    One of the largest historic earthquakes in the Pacific Northwest occurred on 15 December 1872 (M6.5-7) near the south end of Lake Chelan in north-central Washington State. Lack of recognized surface deformation suggested that the earthquake occurred on a blind, perhaps deep, fault. New LiDAR data show landslides and a ~6 km long, NW-side-up scarp in Spencer Canyon, ~30 km south of Lake Chelan. Two landslides in Spencer Canyon impounded small ponds. An historical account indicated that dead trees were visible in one pond in AD1884. Wood from a snag in the pond yielded a calibrated age of AD1670-1940. Tree ring counts show that the oldest living trees on each landslide are 130 and 128 years old. The larger of the two landslides obliterated the scarp and thus, post-dates the last scarp-forming event. Two trenches across the scarp exposed a NW-dipping thrust fault. One trench exposed alluvial fan deposits, Mazama ash, and scarp colluvium cut by a single thrust fault. Three charcoal samples from a colluvium buried during the last fault displacement had calibrated ages between AD1680 and AD1940. The second trench exposed gneiss thrust over colluvium during at least two, and possibly three fault displacements. The younger of two charcoal samples collected from a colluvium below gneiss had a calibrated age of AD1665- AD1905. For an historical constraint, we assume that the lack of felt reports for large earthquakes in the period between 1872 and today indicates that no large earthquakes capable of rupturing the ground surface occurred in the region after the 1872 earthquake; thus the last displacement on the Spencer Canyon scarp cannot post-date the 1872 earthquake. Modeling of the age data suggests that the last displacement occurred between AD1840 and AD1890. These data, combined with the historical record, indicate that this fault is the source of the 1872 earthquake. Analyses of aeromagnetic data reveal lithologic contacts beneath the scarp that form an ENE

    Density data as a function of temperature have been measured for Jatropha curcas seed oil, as well as biodiesel jatropha methyl esters at temperatures from above their melting points to 90 ° C. The data obtained were used to validate the method proposed by Spencer and Danner using a modified Rackett equation. The experimental and estimated density values using the modified Rackett equation gave almost identical values with average absolute percent deviations less than 0.03% for the jatropha oil and 0.04% for the jatropha methyl esters. The Janarthanan empirical equation was also employed to predict jatropha biodiesel densities. This equation performed equally well with average absolute percent deviations within 0.05%. Two simple linear equations for densities of jatropha oil and its methyl esters are also proposed in this study.

  13. On suffering and sympathy: "Jude the Obscure," evolution, and ethics.

    PubMed

    Sumpter, Caroline

    2011-01-01

    This article links Thomas Hardy's exploration of sympathy in "Jude the Obscure" to contemporary scientific debates over moral evolution. Tracing the relationship between pessimism, progressivism, and determinism in Hardy's understanding of sympathy, it also considers Hardy's conception of the author as enlarger of 'social sympathies' - a position, I argue, that was shaped by Leslie Stephen's advocacy of novel writing as moral art. Considering Hardy's engagement with writings by Charles Darwin, T.H. Huxley, Herbert Spencer, and others, I explore the novel's participation in a debate about the evolutionary significance of sympathy and its implications for Hardy's understanding of moral agency. Hardy, I suggest, offered a stronger defence of morality based on biological determinism than Darwin, but this determinism was linked to an unexpected evolutionary optimism. PMID:22355828

    The retina was one of the main objects of study in the first stage of the scientific work of Ramón y Cajal. As culmination of his previous works Cajal published in 1893 in the journal La Cellule an article titled "La rétine des Vertébrés". This article on the retina is a perfect example of Cajal's ability for the systematic study of the cellular types of the nervous centers, its morphological description and its intercellular contacts, as well as for the formulation of physiological interpretations and hypothesis on the development of the neuronal prolongations. Finally some comments are made on the influence of the evolutionary thinking of Haeckel and Herbert Spencer on the work of Ramón y Cajal. PMID:11640477

    PubMed

    Wiest, Gerald

    2012-01-01

    The history of the sciences of the human brain and mind has been characterized from the beginning by two parallel traditions. The prevailing theory that still influences the way current neuroimaging techniques interpret brain function, can be traced back to classical localizational theories, which in turn go back to early phrenological theories. The other approach has its origins in the hierarchical neurological theories of Hughlings-Jackson, which have been influenced by the philosophical conceptions of Herbert Spencer. Another hallmark of the hierarchical tradition, which is also inherent to psychoanalytic metapsychology, is its deeply evolutionary perspective by taking both ontogenetic and phylogenetic trajectories into consideration. This article provides an outline on hierarchical concepts in brain and mind sciences, which contrast with current cognitivistic and non-hierarchical theories in the neurosciences. PMID:23189066

    1990-01-01

    In the three years since its launch, the Special Sensor Microwave Imager (SSM/I) provided the beginnings of a data set crucial to the study of the Earth's global hydrologic cycle. Investigations with SSM/I centered largely on two themes: (1) an analysis of the variability in atmospheric moisture as a signature of dynamic and kinematic processes, and (2) development of high quality data sets for determining moisture balance and, eventually, diabatic heating on regional and planetary scales. To date, most of the emphasis has been on the precipitable water field since algorithms for this quantity appear to be the most mature. In addition, researchers began work with liquid water, precipitating ice and ocean surface wind stress fields. The retrievals used in these studies are from algorithms developed by Wentz (RSS Tech Rpt. 1989) and Spencer (1988 JTECH).

    Neutrino astronomy beyond the Sun was first imagined in the late 1950s; by the 1970s, it was realized that kilometer-scale neutrino detectors were required. The first such instrument, IceCube, is near completion and taking data. Its scientific missions include the observation of Galactic supernova explosions, the search for dark matter, and the study of the neutrinos themselves. These reach energies more than two orders of magnitude beyond those produced by accelerator beams. In these lectures, we will focus on IceCube's most publicized mission, the search for the sources of cosmic rays. We will conclude with an overview of the first results obtained with the partially completed detector.These lectures are based on a review paper co-authored with Spencer Klein (arXiv:astroph.HE/1007.1247) to be published in Review of Scientific Instruments.

    The 500 km long Gulf of Alaska coastline between Cape Suckling and Cape Spencer can be characterized by constant rapid change in an environment of glaciers, stormy climate, high relief, and extreme oceanographic parameters. During a more than 200-year history of observation, bays have completely filled with sediment, new bays have appeared, glaciers have advanced and retreated as much as 40 km, streams have been captured, and spits have grown as much as 10 km in length, earthquakes have uplifted the coast as much as 15 m, and in general, few features have been static. More than 250 km of coastline have undergone erosion and retreat, with maximum retreat exceeding 4 km at Icy Bay.

    2012-01-01

    The history of the sciences of the human brain and mind has been characterized from the beginning by two parallel traditions. The prevailing theory that still influences the way current neuroimaging techniques interpret brain function, can be traced back to classical localizational theories, which in turn go back to early phrenological theories. The other approach has its origins in the hierarchical neurological theories of Hughlings-Jackson, which have been influenced by the philosophical conceptions of Herbert Spencer. Another hallmark of the hierarchical tradition, which is also inherent to psychoanalytic metapsychology, is its deeply evolutionary perspective by taking both ontogenetic and phylogenetic trajectories into consideration. This article provides an outline on hierarchical concepts in brain and mind sciences, which contrast with current cognitivistic and non-hierarchical theories in the neurosciences. PMID:23189066

    Monthly mean fields of select geophysical parameters derived from analysis of AIRS/AMSU data, and their interannual differences, are shown and compared with analogous fields derived from other sources. All AIRS fields are derived using the AIRS Science Team Version 4 algorithm. Monthly mean results are shown for January 2004, as are interannual differences between January 2004 and January 2003. AIRS temperature and water vapor profile fields are compared with monthly mean collocated ECMWF 3 hour forecast and monthly mean TOVS Pathfinder Path A data. AIRS Tropospheric and Stratospheric coarse climate indicators are compared with analogous MSU products derived by Spencer and christy and found in the TOVS Pathfinder Path A data set. Total ozone is compared with results produced by TOMS. OLR is compared with OLR derived using CERES data and found in the TOVS Pathfinder Path A data set. AIRS results agree well in all cases, especially in the interannual difference sense.

    2009-01-01

    Not only was Sir Francis Galton a famous geographer and statistician, he also invented "eugenics" in 1883. Eugenics, defined as the science of improving racial stock, was developed from a new heredity theory, conceived by Galton himself, and from the evolution theory of Charles Darwin, transposed to human society by Herbert Spencer. Galton's eugenics was a program to artificially produce a better human race through regulating marriage and thus procreation. Galton put particular emphasis on "positive eugenics", aimed at encouraging the physically and mentally superior members of the population to choose partners with similar traits. In 1904, he presented his ideas in front of a vast audience of physicians and scientists in London. His widely-publicized lecture served as the starting point for the development of eugenics groups in Europe and the United States during the first half of the 20th century. PMID:19602363

  2. Hamiltonian inclusive fitness: a fitter fitness concept

    PubMed Central

    2013-01-01

    In 1963–1964 W. D. Hamilton introduced the concept of inclusive fitness, the only significant elaboration of Darwinian fitness since the nineteenth century. I discuss the origin of the modern fitness concept, providing context for Hamilton's discovery of inclusive fitness in relation to the puzzle of altruism. While fitness conceptually originates with Darwin, the term itself stems from Spencer and crystallized quantitatively in the early twentieth century. Hamiltonian inclusive fitness, with Price's reformulation, provided the solution to Darwin's ‘special difficulty’—the evolution of caste polymorphism and sterility in social insects. Hamilton further explored the roles of inclusive fitness and reciprocation to tackle Darwin's other difficulty, the evolution of human altruism. The heuristically powerful inclusive fitness concept ramified over the past 50 years: the number and diversity of ‘offspring ideas’ that it has engendered render it a fitter fitness concept, one that Darwin would have appreciated.

    Théodule Ribot (1839-1916) is regarded by many historians of psychology as the "father" of the discipline in France. Ribot contributed to the development of a "new psychology" independent from philosophy, relying on the methods of the natural sciences. However, such an epistemological transition encountered fierce opposition from both the champions of the old-fashioned metaphysical psychology and the representatives of the "scientific spirit." This article focuses on the objections raised by the latter, and especially philosophers of science, against the possibility of a scientific psychology. For instance, according to Auguste Comte, psychology does not satisfy certain basic methodological requirements. To overcome these objections, Ribot, in his La Psychologie Anglaise Contemporaine (1870/1914), devised an epistemological strategy that amounted to invoking criticisms of Comte's views made by other representatives of the positivist school, such as John Stuart Mill and Herbert Spencer.

    1997-01-01

    Seventeen months of rainfall data (August 1987-December 1988) from nine satellite rainfall algorithms (Adler, Chang, Kummerow, Prabhakara, Huffman, Spencer, Susskind, and Wu) were analyzed to examine the uncertainty of satellite-derived rainfall estimates. The variability among algorithms, measured as the standard deviation computed from the ensemble of algorithms, shows regions of high algorithm variability tend to coincide with regions of high rain rates. Histograms of pattern correlation (PC) between algorithms suggest a bimodal distribution, with separation at a PC-value of about 0.85. Applying this threshold as a criteria for similarity, our analyses show that algorithms using the same sensor or satellite input tend to be similar, suggesting the dominance of sampling errors in these satellite estimates.

  5. Deep insight from simple models of evolution.

    2002-01-01

    On one hand, people admire the often strikingly efficient results of organic evolution. On the other hand, however, they decry mutation and selection to be a rather prodigal, inefficient trial-and-error strategy. Taking into account the parallel information processing in a heterogeneous population and sexual propagation with recombination, as well as the genetic control of the reproduction accuracy, computer simulated evolution reveals a couple of interesting, sometimes surprising, properties of nature's learning-by-doing algorithm. Survival of the fittest, Spencer's résumé of Darwin's view, turns out to be a bad advice if taken literally. Individual death, forgetting, and even regression show up to be necessary ingredients of the life game. Whether the process should be named gradualistic or punctualistic, is a matter of the observer's point of view.

    1991-02-15

    Calculation of heating caused by the deposition of x rays in thin-film optical coatings is complicated because the mean free path of photo- and autoionization electrons is comparable to the thin-film thickness and thus electron deposition cannot be considered local. This paper describes the modeling in the computer code XRTH of (a) x-ray deposition and transport, (b) electron production, deposition, and transport, and (c) thermal conduction and transport. X-ray transport is handled by multigroup discrete ordinates, electron transport is done by the method of characteristics, applied to the two-term spherical harmonics expansion approximation ({ital P}{sub 1}) to the Spencer--Lewis transport equation, and thermal transport is computed by a Richardson extrapolation of a backward Euler solution to the heat conduction equation. Results of a few test cases and comparisons with other computer codes are presented.

    2014-03-01

    The idea that the Sun was a gaseous in nature was born from 1858-65. At that time, a group of men, including Herbert Spencer, Father Angelo Secchi, Warren de la Rue, Balfour Stewart, and Benjamin Loewy, advanced that the Sun was a ball of gas. In 1865, Hervé Faye was the first to argue that the solar surface was merely an illusion. Dismissing all signs to the contrary, solar physics has promoted this idea to the present day, as manifested by the Standard Solar Model. In this work, overwhelming observational evidence will be presented that the Sun does indeed possess a distinct surface (see P.M. Robitaille, Forty Lines of Evidence for Condensed Matter -- The Sun on Trial: Liquid Metallic Hydrogen as a Solar Building Block, Progress in Physics, 2013, v. 4, 90-143). Our telescopes and satellites are sampling real structures on the surface of the Sun.

    1996-03-01

    A better understanding of the shock sensitivity of energetic materials is important in designing safer explosives. Experimental studies have shown that the shock sensitivity of single crystals of PETN depends on the orientation of the crystal axis relative to the shock propagation direction.(J. J. Dick, R. N. Mulford, W. J. Spencer, D. R. Pettit, E. Garcia, and D. C. Shaw, J. Appl. Phys.) 70, 3572 (1991). Orientation dependent explosions have also been observed in nitromethane single crystals.(G. J. Piermanarini, S. Block, and P. J. Miller, J. Phys. Chem.) 93, 457 (1989). Recently we have developed potentials to describe shock-induced chemistry and detonation in condensed phase ozone. In this paper we report results of simulations that show that this model predicts a strong orientational dependence in the detonation threshold. An explanation of this orientational dependence in terms of the crystal structure of the model material will be provided.

    2003-11-01

    In Studies 1-3, undergraduates with high self-esteem (HSEs) reacted to personal uncertainty-threats with compensatory conviction about unrelated issues and aspects of the self. In Study 1 HSEs reacted to salience of personal dilemmas with increased implicit conviction about self-definition. In Study 2 they reacted to the same uncertainty-threat with increased explicit conviction about social issues. In Study 3, HSEs (particularly defensive HSEs, i.e., with low implicit self-esteem; C. H. Jordan, S. J. Spencer, & M. P. Zanna, 2003) reacted to uncertainty about a personal relationship with compensatory conviction about social issues. For HSEs in Study 4, expressing convictions about social issues decreased subjective salience of dilemma-related uncertainties that were not related to the social issues. Compensatory conviction is viewed as a mode of repression, akin to reaction formation, that helps keep unwanted thoughts out of awareness.

    he Grubbs-Beck test is recommended by the federal guidelines for detection of low outliers in flood flow frequency computation in the United States. This paper presents a generalization of the Grubbs-Beck test for normal data (similar to the Rosner (1983) test; see also Spencer and McCuen (1996)) that can provide a consistent standard for identifying multiple potentially influential low flows. In cases where low outliers have been identified, they can be represented as “less-than” values, and a frequency distribution can be developed using censored-data statistical techniques, such as the Expected Moments Algorithm. This approach can improve the fit of the right-hand tail of a frequency distribution and provide protection from lack-of-fit due to unimportant but potentially influential low flows (PILFs) in a flood series, thus making the flood frequency analysis procedure more robust.

  14. A note on topological M5-branes and string-fivebrane duality

    2008-06-01

    We derive the stability conditions for the M5-brane in topological M-theory using κ-symmetry. The non-linearly self-dual 3-form on the world-volume is necessarily non-vanishing, as is the case also for the 2-form field strengths on coisotropic branes in topological string theory. It is demonstrated that the self-duality is consistent with the stability conditions, which are solved locally in terms of a tensor in the representation 6 of SU(3)⊂G2. The double dimensional reduction of the M5-brane is the D4-brane, and its direct reduction is an NS5-brane. We show that the equation of motion for the 3-form on the NS5-brane wrapping a Calabi-Yau space is exactly the Kodaira-Spencer equation, providing support for a string-fivebrane duality in topological string theory.

    We find the explicit form of the volume form on the moduli space of non-hyperelliptic Riemann surfaces induced by the Siegel metric, a long-standing question in string theory. This question is related to the explicit form of the (g-2)(g-3)/2 linearly independent relations among the 2-fold products of holomorphic abelian differentials, that are provided in the case of canonical curves of genus g ⩾ 4. Such relations can be completely expressed in terms of determinants of the standard normalized holomorphic abelian differentials. Remarkably, it turns out that the induced volume form is the Kodaira-Spencer map of the square of the Bergman reproducing kernel.

    2005-03-01

    We construct a cubic field theory which provides all genus amplitudes of the topological A-model for all non-compact toric Calabi-Yau threefolds. The topology of a given Feynman diagram encodes the topology of a fixed Calabi-Yau, with Schwinger parameters playing the role of Kähler classes of the threefold. We interpret this result as an operatorial computation of the amplitudes in the B-model mirror which is the quantum Kodaira-Spencer theory. The only degree of freedom of this theory is an unconventional chiral scalar on a Riemann surface. In this setup we identify the B-branes on the mirror Riemann surface as fermions related to the chiral boson by bosonization.

Exploratory research includes work on advanced photovoltaic technologies (organic and ultra-high efficiency solar cells for solar concentrators) as well as innovative approaches to emerging and mature technologies (e.g., crystalline silicon).

  18. On suffering and sympathy: "Jude the Obscure," evolution, and ethics.

    2011-01-01

    This article links Thomas Hardy's exploration of sympathy in "Jude the Obscure" to contemporary scientific debates over moral evolution. Tracing the relationship between pessimism, progressivism, and determinism in Hardy's understanding of sympathy, it also considers Hardy's conception of the author as enlarger of 'social sympathies' - a position, I argue, that was shaped by Leslie Stephen's advocacy of novel writing as moral art. Considering Hardy's engagement with writings by Charles Darwin, T.H. Huxley, Herbert Spencer, and others, I explore the novel's participation in a debate about the evolutionary significance of sympathy and its implications for Hardy's understanding of moral agency. Hardy, I suggest, offered a stronger defence of morality based on biological determinism than Darwin, but this determinism was linked to an unexpected evolutionary optimism.

As culmination of his previous works Cajal published in 1893 in the journal La Cellule an article titled "La rétine des Vertébrés". This article on the retina is a perfect example of Cajal's ability for the systematic study of the cellular types of the nervous centers, its morphological description and its intercellular contacts, as well as for the formulation of physiological interpretations and hypothesis on the development of the neuronal prolongations. Finally some comments are made on the influence of the evolutionary thinking of Haeckel and Herbert Spencer on the work of Ramón y Cajal.

    The authors tested the extent to which the personality dimensions of neuroticism, extraversion, and psychoticism (H. J. Eysenck & S. B. G. Eysenck, 1975) prospectively predicted global anxiety (assessed by items from the Brief Symptom Inventory: L. R. Derogatis & M. S. Spencer, 1982). The authors also examined prospective relations among these personality dimensions and depression to evaluate the specificity of findings. Participants were 466 young adults, primarily undergraduate students, assessed twice over a 3-year interval. An interaction between neuroticism and extraversion predicted both global anxiety and depression 3 years later. Findings indicated that personality, in particular the combination of high neuroticism and low extraversion, may play an important predisposing, etiological role in anxiety. Interpretations and implications of the predictive importance of the Neuroticism x Extraversion interaction in anxiety are discussed, and further speculations about the relation between anxiety and depression are put forth.

  2. Watersheds and Explosive percolation

    Herrmann, Hans J.; Araujo, Nuno A. M.

    The recent work by Achlioptas, D'Souza, and Spencer opened up the possibility of obtaining a discontinuous (explosive) percolation transition by changing the stochastic rule of bond occupation. Despite the active research on this subject, several questions still remain open about the leading mechanism and the properties of the system. We review the largest cluster and the Gaussian models recently introduced. We show that, to obtain a discontinuous transition it is solely necessary to control the size of the largest cluster, suppressing the growth of a cluster di_ering significantly, in size, from the average one. As expected for a discontinuous transition, a Gaussian cluster-size distribution and compact clusters are obtained. The surface of the clusters is fractal, with the same fractal dimension of the watershed line.

    2010-11-01

    Clusters generated by the product-rule growth model of Achlioptas, D’Souza, and Spencer on a two-dimensional square lattice are shown to obey qualitatively different scaling behavior than standard (random growth) percolation. The threshold with unrestricted bond placement (allowing loops) is found precisely using several different criteria based on both moments and wrapping probabilities, yielding pc=0.526565±0.000005 , consistent with the recent result of Radicchi and Fortunato. The correlation-length exponent ν is found to be close to 1. The qualitative difference from regular percolation is shown dramatically in the behavior of the percolation probability P∞ (size of largest cluster), of the susceptibility, and of the second moment of finite clusters, where discontinuities appear at the threshold. The critical cluster-size distribution does not follow a consistent power law for the range of system sizes we study (L≤8192) but may approach a power law with τ>2 for larger L .

    The Spencer Gulf Rural Health School (SGRHS), South Australia, is funded by the Australian Commonwealth Government to deliver health education in the rural setting. The SGRHS required a database to record, track and report on student rural placements to satisfy Commonwealth reporting requirements, and for internal academic and administration staff use. Staff in widely separate rural locations needed to be able to access the database. A web-based relational database was created using Microsoft Access. The student rural placement database has been successfully utilised as the primary tool to record and track student placements in the SGRHS for 2 years, and has generated data for eight Commonwealth reports in this time. Future database developments include student accessible sections. With few alterations the database could be utilised by other Australian Rural Clinical Schools and University Departments of Rural Health.

    The authors considered the mental health consequences of polygamy in a sample of 101 Arab Muslim adolescents (19 from polygamous and 82 from monogamous families) at Juarish (Ramla), Israel. The respondents completed the Self-Esteem Scale (SE; M. Rosenberg, 1979), the Brief Symptom Inventory (BSI; L. Derogatis & N. Melsavados, 1983; L. Derogatis & P. Spencer, 1982), and the McMaster Family Assessment Device (FAD; N. B. Epstein, M. N. Baldwin, & D. S. Bishop, 1983). The respondents from polygamous families had lower SE scores, statistically significant higher scores in 2 BSI dimensions, higher scores in all other BSI dimensions, and higher levels of self-reported family dysfunction. The respondents from polygamous families reported lower levels of socioeconomic status, academic achievement, and parental academic attainment. Those variables may have had a more direct impact on mental health than did parental marital status. The data also indicated that perceived family functioning was the best predictor of mental health.

    If gender is a confounder of the decompression sickness (DCS) or venous gas emboli (VGE) outcomes of a proposed air break in oxygen prebreathe (PB) project, then decisions about the final experiment design must be made. We evaluated if the incidence of DCS and VGE from tests in altitude chambers over 20 years were different between men and women after resting and exercise PB protocols. Nitrogen washout during PB is our primary risk mitigation strategy to prevent subsequent DCS and VGE in subjects. Bubbles in the pulmonary artery (venous blood) were detected from the precordial position using Doppler ultrasound bubble detectors. The subjects were monitored for VGE for four min at about 15 min intervals for the duration of the altitude exposure, with maximum bubble grade assigned a Spencer Grade of IV.

    A study aimed at the evaluation of the stability of the Ririe Dam in Idaho was undertaken. The work is to be performed in two phases, the first of which is devoted to two-dimensional (2D) analyses, while the second is concerned with the investigation of the influence of the three-dimensional effects on the overall stability of the dam. This report presents results of Phase I of the program. An extensive number of effective stress stability analyses involving both circular and non-circular failure surfaces were performed using three different methods of stability analyses, namely the modified Bishop, Spencer and MIT methods. Both gravity and earthquake loadings were considered. Circular arc analyses for gravity loading were performed using the computer program STAB3D, whereas the program TSLOPE was utilized for all other analyses.

  11. Phase portraits of the proliferation-quiescence decision.

    Mammalian cells make the proliferation or quiescence decision at a specific point in the cell cycle called the restriction point, after which they become committed to proliferation and independent of growth factors for completion of mitosis. In the textbook view, this crucial transition occurs several hours after mitotic division (in the middle of G1 phase). In a Cell paper, Spencer et al. show that the restriction point should be defined not as a particular time point in G1 phase but in terms of the ON-OFF status of a bistable switch that emerges from the positive feedback in the CDK2-RB-E2F (cyclin-dependent kinase 2-retinoblastoma-E2F) interaction network.

    This report consists of two code manuals and an article recently published in the proceedings of the American Nuclear Society Mathematics and Computation Topical Meeting held in Pittsburgh. In these presentations, deterministic calculational methods simulating electron transport in solids are detailed. The first method presented (Section 2) is for the solution of the Spencer-Lewis equation in which electron motion is characterized by continuous slowing down theory and a pathlength formulation. The FN solution to the standard monoenergetic transport equation for electron transport with isotropic scattering in finite media is given in Section 3. For both codes, complete flow charts, operational instructions and sample problems are included. Finally, in Section 4, an application of the multigroup formulation of electron transport in an infinite medium is used to verify an equivalent SN formulation. For this case, anisotropic scattering is also included.

    On February 14, 2002, U.S. Secretary of Energy Spencer Abraham provided to the President the ''Recommendation by the Secretary of Energy Regarding the Suitability of the Yucca Mountain Site for a Repository Under the Nuclear Waste Policy Act of 1982.'' This Recommendation, along with supporting materials, complied with statutory requirements for communicating a site recommendation to the President, and it did more: in 49 pages, the Recommendation also spoke directly to the Nation, illuminating the methodology and considerations that led toward the decision to recommend the site. Addressing technical suitability, national interests, and public concerns, the Recommendation helped the public understand the potential risks and benefits of repository development and placed those risks and benefits in a meaningful national context.

    The first intraabdominal operation where the patient survived was an ovariotomy performed by Ephraim McDowell Christmas Day 1809. The patient was mrs. Jane Todd Crawford and in her pain and desperation she appeared willing to undergo the operation. After five weeks she was cured and on horseback she went back to Greensburg where she lived. In Great Britain the famous surgeon Spencer Wells was the most important of the pioneers. He performed over twelve hundred ovariotomies. But in Denmark the first nine patients died. Then Julius Boye - a general practitioner and a farmer, but also a selfmade surgeon - published a case in 1867 where the patient survived.. He had performed the operation and many others in a little house in the country far from hospitals. You may say that the house was a Private Hospital When Boye had presented his case the ovariotomy soon became a routine operation like others.

    We have done extensive disk-integrated photometry of volcanic thermal emission from Io's Jupiter-facing hemisphere at 1.7 and 2.3 microns, using the OSIRIS infrared camera on the 72'' Perkins telescope at Lowell Observatory, to monitor volcanic activity in support of the Galileo mission. We have data from 13 nights between March and October 1995, and on 6 nights between April and July 1996. Observations were taken when Io was eclipsed by Jupiter in order to eliminate reflected sunlight. At these short wavelengths, measurements are sensitive to the hottest volcanic temperatures. Additional observations at the same wavelengths were done with the IRTF on Mauna Kea. In all 1996 observations, and through much of 1995, volcanic activity was low, Io typically being no brighter than 11th magnitude at 2.3 microns. However, a tenfold brightening was seen in late March 1995, fading in less than six weeks, and Io was also unusually bright between late July and early October 1995, as a result of eruptions at Loki and two new hot spots (Spencer et al., this volume). High 1.7:2.3 micron color temperatures were found: 1070 +/- 40 K on August 26, 1995, when Io was relatively bright, and 925 +/- 30 K on June 2, 1996, when Io was faint, strongly suggest the presence of continuous silicate volcanism on Io. The results of this work will be combined with work in progress (Spencer et al., this volume), to locate the individual hot spots and determine their temperature/area history.

  18. Ozone Production in Irradiated Laboratory Ices Relevant to Europa and Ganymede

    Observations suggest ozone (O3) is present on the icy surfaces of Ganymede (1), and Rhea and Dione (2). Molecular oxygen (O2) has also been observed on Europa (3) and Ganymede (4). The formation and trapping of such molecules in ice and their subsequent transportation to a sub-surface ocean may be potentially important for sustaining astrobiological life (5). It is assumed that ozone is produced in these icy surfaces by the addition of an oxygen atom to molecular oxygen, with the latter formed by prior irradiation of the water ice. The infrared absorption band of ozone in ice at 1037 cm-1 is strong and thus makes ozone a good tracer for the presence of molecular oxygen which is difficult to detect. We will present results of water/oxygen ices irradiated with 800 keV protons and show the band position and growth of ozone with increasing radiation dose. The thermal stability of this radiolytically-produced ozone has also been measured and comparisons made to the Jovian satellites. P. Cooper is grateful for the support from the National Academies Research Associateship Program. (1) Noll, K.S., Johnson, R.E., Lane, A.L., Domingue, D.L., Weaver, H.A., Science, 273, 341-343, (1996).

  19. Strategies and methodologies to develop techniques for computer-assisted analysis of gas phase formation during altitude decompression

    It would be of operational significance if one possessed a device that would indicate the presence of gas phase formation in the body during hypobaric decompression. Automated analysis of Doppler gas bubble signals has been attempted for 2 decades but with generally unfavorable results, except with surgically implanted transducers. Recently, efforts have intensified with the introduction of low-cost computer programs. Current NASA work is directed towards the development of a computer-assisted method specifically targeted to EVA, and we are most interested in Spencer Grade 4. We note that Spencer Doppler Grades 1 to 3 have increased in the FFT sonogram and spectrogram in the amplitude domain, and the frequency domain is sometimes increased over that created by the normal blood flow envelope. The amplitude perturbations are of very short duration, in both systole and diastole and at random temporal positions. Grade 4 is characteristic in the amplitude domain but with modest increases in the FFT sonogram and spectral frequency power from 2K to 4K over all of the cardiac cycle. Heart valve motion appears to characteristic display signals: (1) the demodulated Doppler signal amplitude is considerably above the Doppler-shifted blow flow signal (even Grade 4); and (2) demodulated Doppler frequency shifts are considerably greater (often several kHz) than the upper edge of the blood flow envelope. Knowledge of these facts will aid in the construction of a real-time, computer-assisted discriminator to eliminate cardiac motion artifacts. There could also exist perturbations in the following: (1) modifications of the pattern of blood flow in accordance with Poiseuille's Law, (2) flow changes with a change in the Reynolds number, (3) an increase in the pulsatility index, and/or (4) diminished diastolic flow or 'runoff.' Doppler ultrasound devices have been constructed with a three-transducer array and a pulsed frequency generator.

    This study reports the development and evaluation of a novel method using quantitative light-induced fluorescence (QLF), which enables its use for quantifying and assessing whole tooth surface staining and tooth whitening. The method was compared with a spectrophotometer to assess reliability. Two experimental phases, intrinsic stain formation and tooth whitening, were conducted in vitro on 16 extracted bovine teeth. Intrinsic stains were developed via access through lingual surfaces and root canals of these teeth using tea solution (2 g/100 ml, Marks and Spencer Extra Strong Tea, Marks and Spencer, London, UK) for 6 days. Stains were removed using 33% hydrogen peroxide (VWR Prolab, Leicestershire, UK) in cycles over 150 min. Stain development/whitening was monitored with QLF (Inspektor Research systems, Amsterdam, Netherlands) and spectrophotometry (Easy shade, Vita Zahnfabrik, Bad Säckingen, Germany). Parameters Delta F for QLF and Delta E for the spectrophotometer were obtained. The progression of stain intensity and removal observed by the methods were tested for correlation using Pearson's correlation coefficient. Intra-examiner reliability for each method was tested. QLF showed a high correlation with spectrophotometry for detecting and monitoring intrinsic tooth stain progression (Pearson coefficient r was -0.987 with correlation significant p < 0.0001). For stain removal, the Pearson coefficient (r) between both methods was -0.906 with no significance p = 0.094. The use of an external reference material in combination with the inner patch QLF analysis technique had the ability to detect and measure whole tooth surface staining and its removal longitudinally. The reliability of the method shows a potential clinical application. PMID:19306025

    We examined the reliability and ease of use of a novel automated transcranial Doppler (TCD) system in comparison to a conventional TCD system. TCD ultrasound allows non-invasive monitoring of cerebral blood flow, and can predict arterial vasospasm after a subarachnoid hemorrhage (SAH). The Presto 1000 TCD system (PhysioSonics, Bellevue, WA, USA) is designed for monitoring flow through the M1 segment of the middle cerebral artery (MCA) via temporal windows. The Presto 1000 system was tested across multiple preclinical and clinical settings in parallel with a control predicate TCD system. In a phantom flow generating device, both the Presto 1000 and Spencer system (Spencer Technologies, Redmond, WA, USA) were able to detect velocities with high accuracy. In nine volunteer patients, the Presto system was able to locate the MCA in 14 out of 18 temporal windows, in an average of 12.5s. In the SAH cohort of five patients with a total of 25 paired measurements, the mean absolute difference in flow velocities of the M1 segment, as measured by the two systems, was 17.5 cm/s. These data suggest that the Presto system offers an automated TCD that can reliably localize and detect flow of the MCA, with relative ease of use. The system carries the additional benefit of requiring minimal training for the operator, and can be used by many providers across multiple bedside settings. The mean velocities that were generated warrant further validation across an extended group of patients, and the predictive value for vasospasm should be checked against the current standard of angiography.

    In spite of many modifications to decompression algorithms, the incidence of decompression sickness (DCS) in scuba divers has changed very little. The success of stage, compared to linear ascents, is well described yet theoretical changes in decompression ratios have diminished the importance of fast tissue gas tensions as critical for bubble generation. The most serious signs and symptoms of DCS involve the spinal cord, with a tissue half time of only 12.5 minutes. It is proposed that present decompression schedules do not permit sufficient gas elimination from such fast tissues, resulting in bubble formation. Further, it is hypothesized that introduction of a deep stop will significantly reduce fast tissue bubble formation and neurological DCS risk. A total of 181 dives were made to 82 fsw (25 m) by 22 volunteers. Two dives of 25 min and 20 min were made, with a 3 hr 30 min surface interval and according to 8 different ascent protocols. Ascent rates of 10, 33 or 60 fsw/min (3, 10, 18 m/min) were combined with no stops or a shallow stop at 20 fsw (6 m) or a deep stop at 50 fsw (15 m) and a shallow at 20 fsw (6 m). The highest bubbles scores (8.78/9.97), using the Spencer Scale (SS) and Extended Spencer Scale (ESS) respectively, were with the slowest ascent rate. This also showed the highest 5 min and 10 min tissue loads of 48% and 75%. The lowest bubble scores (1.79/2.50) were with an ascent rate of 33 fsw (10 m/min) and stops for 5 min at 50 fsw (15 m) and 20 fsw (6 m). This also showed the lowest 5 and 10 min tissue loads at 25% and 52% respectively. Thus, introduction of a deep stop significantly reduced Doppler detected bubbles together with tissue gas tensions in the 5 and 10 min tissues, which has implications for reducing the incidence of neurological DCS in divers.

    Major prehistoric forces, such as the climatic shifts of the Pleistocene, can remain visible in a species’ population genetics. Inference of refuges via genetic tools is useful for conservation management as it can identify populations whose preservation may help retain a species’ adaptive potential. Such investigation is needed for Australia’s southern hairy-nosed wombat (Lasiorhinus latifrons), whose conservation status has recently deteriorated, and whose phylogeographic history during the Pleistocene may be atypical compared to other species. Its contemporary range spans approximately 2000 km of diverse habitat on either side of the Spencer Gulf, which was a land bridge during periods of Pleistocene aridity that may have allowed for migration circumventing the arid Eyrean barrier. We sampled from animals in nearly all known sites within the species’ current distribution, mainly using non-invasive methods, and employed nuclear and mitochondrial DNA analyses to assess alternative scenarios for Pleistocene impacts on population structure. We found evidence for mildly differentiated populations at the range extremes on either side of Spencer Gulf, with secondary contact between locations neighbouring each side of the barrier. These extreme western and eastern regions, and four other regions in between, were genetically distinct in genotypic clustering analyses. Estimates indicate modest, but complex gene flow patterns among some of these regions, in some cases possibly restricted for several thousand years. Prior to this study there was little information to aid risk assessment and prioritization of conservation interventions facilitating gene flow among populations of this species. The contributions of this study to that issue are outlined. PMID:27732594

  4. Oxygen investigation in the Galileian satellites using AFOSC

    Migliorini, A.; Barbieri, M.; Piccioni, G.; Barbieri, C.; Altieri, F.

    Spectroscopy in the visible range of the Galilean satellites is a suitable way to investigate the surface properties of these objects. In recent years, several species, like O_2, O_3, and SO_2, have been detected on the surfaces of these satellites, which were thought to be completely covered only by water ice. The recent detection of the O_2 absorption bands in the Ganymede trailing face \\citep{spencer_1995} led to laboratory experiments in order to better constraint the O_2 phases trapped in the water ice surface \\citep{vidal_1997}. The same features were observed also on Europa and Callisto surfaces \\citep{spencer_2002}, although a better investigation of their properties and their variability with time is still not fully addressed. We proposed ground-based observations with the AFOSC instrument on the 1.8-m telescope in Asiago, to investigate the Galilean satellites? surface properties, focusing both on the leading and trailing faces of the satellites. We used the Volume Phase Holographic grism covering the spectral range 400-1000 nm, with a spectral resolution of about 5000. In this work, we show results of the observations acquired in November 2014, focusing on the leading faces of the satellites. Data were treated using standard methods of data reduction. Further observations with the same setup, scheduled for February 2015 to observe the trailing face of the Galileian satellites, will complement the program. These observations are in preparation to the future science we will be able to perform with the MAJIS spectrometer on the European JUICE mission.

    The thermal dichotomy of Enceladus suggests an asymmetrical structure in its global heat transfer [1]. So far, most of the models proposed that obtained such a distribution have prescribed an a priori asymmetry, i.e. a mechanical anomaly in the south polar ice shell surface [2], at its base [3], or in core topography [4]. We present here the first set of numerical simulations of convection that yield a stable single-plume state for Enceladus without prescribed mechanical asymmetry. Using the convection code StagYY [5,6] in a 2D-spherical annulus geometry [7], we show that a non-Newtonian rheology is sufficient to create a localized, single hot plume surrounded by a conductive ice mantle. Using a grain size-dependent rheology [8,9], we obtain a self-sustained state in which a region of small angular extent has a sufficiently low viscosity to allow convection to occur due to the stress-dependent part of the rheological law. We find that the single-plume state is very unlikely to remain stable if the rheology is Newtonian. For simplicity, we neglect tidal heating effects. Despite this, our preferred model yields a south polar heat flux which is about half the recently revised observational value [10]. References: [1] Spencer and Nimmo, 2013, An. Rev. Earth Plan.

    It is desirable to know if astronauts produce venous gas emboli (VGE) as a result of their exposure to 4.3 psia during space walks. The current prototype in-suit Doppler (ISD) ultrasound bubble detector provides an objective assessment of decompression stress by monitoring for VGE. The NOAA Aquarius habitat and NASA Extreme Environment Mission Operations (NEEMO) series of dives provided an opportunity to assess the ability of the prototype ISDs to record venous blood flow and possibly detect VGE in the pulmonary artery. From July 16 to 29,2003, four aquanauts (two males and two females) donned the ISD for a 4 hr automated recording session, following excursion dives (up to 6hrs and 29 MSW below storage depth) from air saturation at 17 MSW. Doppler recordings for 32 excursion dives were collected. The recordings consisted of approximately 150 digital wave files. Each wave file contained 24 sec of recording for each min. A 1 - 4 Doppler Quality Score (DQS) was assigned to each wave file in 17 of the 32 records evaluated to date. A DQS of 1 indicates a poor flow signal and a score of 4 indicates an optimum signal. Only 23% of all wave files had DQSs considered adequate to detect low grade VGE (Spencer I-II). The distribution of DQS in 2,356 wave files is as follows: DQS 1-56%, DQS 2-21%, DQS 3-18% and DQS 4-5%. Six of the 17 records had false positive VGE (Spencer I-IV) detected in one or more wave files per dive record. The false positive VGE recordings are attributable to air entrainment associated with drinking (verified by control tests), and this observation is important as astronauts drink water during space walks. The current ISD design provides quality recordings only over a narrow range of chest anatomy.

    A desalination plant is proposed to be the major water supply to the Olympic Dam Expansion Mining project. Located in the Upper Spencer Gulf, South Australia, the site was chosen due to the existence of strong currents and their likely advantages in terms of mixing and dilution of discharged return water. A high-resolution hydrodynamic model (Estuary, Lake and Coastal Ocean Model, ELCOM) was constructed and, through a rigorous review process, was shown to reproduce the intricate details of the Spencer Gulf dynamics, including those characterising the discharge site. Notwithstanding this, it was found that deploying typically adopted 'direct insertion' techniques to simulate the brine discharge within the hydrodynamic model was problematic. Specifically, it was found that in this study the direct insertion technique delivered highly conservative brine dilution predictions in and around the proposed site, and that these were grid and time-step dependent. To improve the predictive capability, a strategy to link validated computational fluid dynamics (CFD) predictions to hydrodynamic simulations was devised. In this strategy, environmental conditions from ELCOM were used to produce boundary conditions for execution of a suite of CFD simulations. In turn, the CFD simulations provided the brine dilutions and flow rates to be applied in ELCOM. In order to conserve mass in a system-wide sense, artificial salt sinks were introduced to the ELCOM model such that salt quantities were conserved. As a result of this process, ELCOM predictions were naturally very similar to CFD predictions near the diffuser, whilst at the same time they produced an area of influence (further afield) comparable to direct insertion methods. It was concluded that the linkage of the models, in comparison to direct insertion methods, constituted a more realistic and defensible alternative to predict the far-field dispersion of outfall discharges, particularly with regards to the estimation of brine

    We report on an investigation of the spatial distribution of Io's atmosphere, and its diurnal variability, using Hubble's Space Telescope Imaging Spectrograph (HST/STIS). From December 2010 to January 2012, we obtained spatially resolved limb-to-limb 2100-3100 Å spectra at low latitudes (<30°), with the STIS 0.1″ slit. Spectra taken at two central meridian longitudes (CMLs), 200 and 250W, over regions that are both bright and dark at near-UV (3000-4000 Å) wavelengths, allowed investigation of the variation in atmospheric density with terrain type and local time. The combined longitudinal coverage of these observations extends from 120 to 320W longitude, and observations of the 200-250W longitude region are obtained at 2 distinct times of day, differing by 50° of rotation of Io. Using primarily SO2 gas absorptions from 2100 to 2300 Å, we detect SO2 gas densities ranging from 0.3 to 2.2 × 1017 cm-2, and 100-200 K gas temperatures. Because we avoided known persistent plume sites, and see little enhancement of SO2 density near known active volcanic centers, we conclude that SO2 gas densities ∼2 × 1017 cm-2 can be obtained via sublimation alone. We correct column densities at each location to equatorial values by assuming vapor-pressure equilibrium with frost at temperatures that vary as cosine1/4(latitude), as inferred from earlier low latitude HST/STIS observations (Jessup, K.L., Spencer, J.R., Ballester, G.E., Howell, R.R., Roesler, F., Vigil, M., Yelle, R.

    The Journal of Optical Networking (JON) invites submissions to a special issue on Convergence. Convergence has become a popular theme in telecommunications, one that has broad implications across all segments of the industry. Continual evolution of technology and applications continues to erase lines between traditionally separate lines of business, with dramatic consequences for vendors, service providers, and consumers. Spectacular advances in all layers of optical networking-leading to abundant, dynamic, cost-effective, and reliable wide-area and local-area connections-have been essential drivers of this evolution. As services and networks continue to evolve towards some notion of convergence, the continued role of optical networks must be explored. One vision of convergence renders all information in a common packet (especially IP) format. This vision is driven by the proliferation of data services. For example, time-division multiplexed (TDM) voice becomes VoIP. Analog cable-television signals become MPEG bits streamed to digital set-top boxes. T1 or OC-N private lines migrate to Ethernet virtual private networks (VPNs). All these packets coexist peacefully within a single packet-routing methodology built on an optical transport layer that combines the flexibility and cost of data networks with telecom-grade reliability. While this vision is appealing in its simplicity and shared widely, specifics of implementation raise many challenges and differences of opinion. For example, many seek to expand the role of Ethernet in these transport networks, while massive efforts are underway to make traditional TDM networks more data friendly

    This article presents the results of the chemical structure research of organic sorbent surface such as walnut shells, plums stones and sunflower hulls with using such methods as infrared spectrometry (FTIR) and elemental analysis. Based on the IR spectra identification of functional groups present on the surface of studied materials has been done as well as determination of their effect on the sorption mechanism of Pb2+ ions from aqueous model solutions W artykule przedstawiono wyniki badań chemicznej struktury powierzchni sorbentów organicznych takich jak: łupiny orzecha włoskiego, pestki śliwek oraz łuski słonecznika z wykorzystaniem metody spektrometrii w podczerwieni (FTIR) oraz analizy elementarnej. W oparciu o uzyskane widma IR dokonano identyfikacji grup funkcyjnych obecnych na powierzchni tych materiałów i określono ich wpływ na mechanizm sorpcji jonów Pb2+ z modelowych roztworów wodnych. Analiza elementarna wykazała, że spośród badanych sorbentów, największą zawartość węgla (49,91%) i wodoru (5,93%) mają pestki śliwek. Najwięcej azotu (1,59%) zawierają łuszczyny słonecznika (tabela 1). Zawartość siarki we wszystkich badanych materiałach jest znikoma, dlatego nie udało się jej oznaczyć tą metodą. Obecność pozostałych pierwiastków może świadczyć o istnieniu zarówno alifatycznych jak i aromatycznych połączeń organicznych. Potwierdzeniem tego są również zarejestrowane widma IR (rysunki 1-3). W oparciu o uzyskane wyniki można przypuszczać także, iż udział procesu wymiany jonowej w sorpcji ołowiu z roztworów wodnych jest znaczący. Świadczą o tym m.in. intensywności pasm na widmach IR dla próbek badanych materiałów po ich kontakcie z roztworami jonów Pb2+ (rysunki 4-6).

    The murine anti-CD18 mAb 1B4 has been humanized using CDR grafting. Three VH (Gal, Jon, and New) and two VL (Rei and Len) human frameworks, whose selection was based exclusively on their sequence identity with m1B4, were used to construct five human gamma 4/kappa recombinant antibodies: Gal/Rei, Gal/Len, Jon/Rei, and New/Rei, and a "hemichimeric" antibody pairing the VH of m1B4 with grafted Rei. Each of these h1B4 constructs completely inhibited the binding of m1B4 to activated human leukocytes with avidities (IC50) ranging from 1.5 to 8.0 nM, compared to 0.5 nM for m1B4. Replacement of three VH residues in the best VH framework, Gal, with the corresponding m1B4 "packing" (nonsolvent exposed) residues gave an h1B4 (mutant Gal/Rei) with the same avidity as m1B4. Avidity correlated with overall percent identity between the human and murine VH frameworks and, in particular, with conservation of "packing" residues. Rei and Len VL frameworks proved to be interchangeable. Further characterization showed that the Gal/Rei prototype was equipotent to m1B4 in blocking adhesion of polymorphonuclear leukocytes and monocytes to human vascular endothelium in vitro, and polymorphonuclear leukocyte extravasation into C5a-injected rabbit or monkey skin sites. Dual-label immunofluorescence microscopy of bone marrow cells with Gal/Rei h1B4 and m1B4 demonstrated that the fine specificity of the combining sites had not been altered by humanization. Reduced immunogenicity was demonstrated in rhesus monkeys that tolerated weekly treatment with h1B4 for 6 wk, whereas m1B4 induced profound anaphylaxis at 3 wk. Anti-1B4 titers in h1B4-treated rhesus were 50 to 66% lower and developed 1 wk later than in m1B4-treated monkeys. Crucially, the anti-h1B4 antibodies were anti-idiotypic while the anti-m1B4 antibodies were directed against constant and framework regions. We conclude that sequence identity searches are sufficient to identify suitable human frameworks for CDR-grafting of m1B4

    , quantum theory is not accessible to even well prepared introductory students, except in a qualitative, often confusing, version. Gillespie, Spencer, and Moog (page 617) provide a new way of introducing the idea of electron configurations that is based on experimental data instead of theoretical quantum numbers. Beginning with the periodic table they develop the inference that electrons must be arranged in shells. They then use ionization potentials and photoelectron spectra to develop further the ideas of shell and subshell. This provides a radically different approach that is at the same time based more firmly on experiment and more accessible to students. Gillespie, Spencer, and Moog (page 622) describe an approach to molecular structure that is closely related to the VSEPR theory originally developed by Gillespie and Nyholm, but does not depend on the orbitals or quantum mechanics. Their electron domain model is based on electron spin and electron pairs but not orbitals and provides an interesting way for students to be introduced to the idea of structure. Birk and Abbassian (page 636) provide a way of visualizing either orbitals or electron domains that uses readily available, inexpensive plastic eggs and is a nice complement to Gillespie, Spencer, and Moog's article. Spencer, Moog, and Gillespie's third article based on the work of the Task Force on the General Chemistry Curriculum begins on page 627. It develops the idea of average valence electron energy and applies it to determining electronegativity values. In the fourth article in this Forum collection, Spencer, Moog, and Gillespie (page 631) propose that students can much more readily assimilate the ideas of reaction thermodynamics if changes in enthalpy, entropy, and free energy are all developed in terms of complete atomization of all reactants followed by putting the atoms back together in a different way to form products. Their tables of enthalpies, entropies, and free energies of atomization will be

    1996-01-01

    INTRODUCTION: In the U.S. Geological Survey's (USGS) 1995 National Assessment of United States oil and gas resources (Gautier and others, 1995), the Appalachian basin was estimated to have, at a mean value, about 61 trillion cubic feet (TCF) of recoverable gas in sandstone and shale reservoirs of Paleozoic age. Approximately one-half of this gas resource is estimated to reside in a regionally extensive, continuous-type gas accumulation whose reservoirs consist of low-permeability sandstone of the Lower Silurian 'Clinton' sands and Medina Group (Gautier and others, 1995; Ryder, 1995). Recognizing the importance of this large regional gas accumulation for future energy considerations, the USGS initiated in January 1995 a multi-year study to evaluate the nature, distribution, and origin of natural gas in the 'Clinton' sands, Medina Group sandstones, and equivalent Tuscarora Sandstone. The project is part of a larger natural gas project, Continuous Gas Accumulations in Sandstones and Carbonates, coordinated in FY1995 by Ben E. Law and Jennie L. Ridgley, USGS, Denver. Approximately 2.6 man years were devoted to the Clinton/Medina project in FY1995. A continuous-type gas accumulation, referred to in the project, is a new term introduced by Schmoker (1995a) to identify those natural gas accumulations whose reservoirs are charged throughout with gas over a large area and whose entrapment does not involve a downdip gas-water contact. Gas in these accumulations is located downdip of the water column and, thus, is the reverse of conventional-type hydrocarbon accumulations. Commonly used industry terms that are more or less synonymous with continuous-type gas accumulations include basin- centered gas accumulation (Rose and others, 1984; Law and Spencer, 1993), tight (low-permeability) gas reservoir (Spencer, 1989; Law and others, 1989; Perry, 1994), and deep basin gas (Masters, 1979, 1984).

The Spencer formation, better exposed in the east-central part of the Coast Ranges, contains marine fossils but also has thin impure coal beds, indicative of strand-line accumulation. The sandstone in the Spencer formation is very similar to that in the Tyee formation, from which it was probably derived. The Fisher formation contains about 5,500 feet of nonmarine pyroclastic and volcanic rocks that are related to the volcanic rock sequences of the western Cascade Range. The formation is characterized by a wide variety of rock types, including conglomerate, tuffaceous sandstone and siltstone, vitric and crystal tuff, waterlaid and mudflow breccia, and andesitic lava flows. These rocks gen- erally occur in lenticular beds that have little stratigraphic significance. The rocks apparently accumulated on a plain slightly above sea level that was subjected alternately to fiooding by running water and to desiccation. Fossil leaves from the lowermost part of the Fisher formation are of late Eocene age; the upper part of the formation is of early, and possibly niiddle, Oligocene age. A few exposures of olivine basalt were mapped in the extreme northern part of the Anlauf quadrangle. The flows, more extensively exposed to the north, overlie the Fisher formation, and, therefore, are tentatively considered to be post-Oligocene in age. All these stratigraphic units, but principally the Fisher formation, are cut by dikes, sills, and stocklike bodies of 'porphyritic basalt, diabase, and norite. Contemporaneously with the emplacement of most of these rocks, in late Miocene (?) time, hydrothermal solutions locailly altered the sedimentary and extrusive igneous racks and deposited cinnabar and other sulfide minerals, carbonates, and silica.

    2014-04-01

    This paper examines mindfulness as a popular and paradigmatic alternative healing practice within the context of contemporary medicalization trends. In recognition of the increasingly influential role popular media play in shaping ideas about illness and healing, what follows is a discursive analysis of bestselling mindfulness meditation self-help books and audio recordings by Jon Kabat-Zinn. The central and contradictory elements of this do-it-yourself healing practice as presented in these materials are best understood as aligned with medicalization trends for three principal reasons. First, mindfulness represents a significant expansion in the definition of disease beyond that advanced by mainstream medicine. Second, its etiological model intensifies the need for therapeutic surveillance and intervention. Third, by defining healing as a never-ending process, it permanently locates individuals within a disease-therapy cycle. In sum, the definition, cause, and treatment of disease as articulated by popular mindfulness resources expands the terrain of experiences and problems that are mediated by medical concepts. The case of mindfulness is a potent illustration of the changing character of medicalization itself.

We intend to identify useful theory and tools, point out connections between different areas, and to a large extent, raise a number of questions whose answers may still lie far beyond the limits of out current knowledge. Some of these areas are still in a very primitive state and call for new ideas, bold approaches, radical thinking and perhaps extraordinary efforts.

    The Physics Force is a very successful and entertaining outreach program of the Institute of Technology in the University of Minnesota developed to make science exciting and fun for students of all ages, from 6 to 106. Although all attendees, including high school and college students and guests from retirement homes, praise our performances, the primary focus is on K-6 students. The original Force consists of six k-12 teachers, Hank Ryan, Jon Barber, Jack Netland, Fred Orsted, Aaron Pinski, and Jay Dornfeld and Dan Dahlberg of the University of Minnesota Physics Department. The Force performed variations of The Physics Circus, our most popular show, at Disney's Epcot Center, parts of it were shown on Newton's Apple and several of us have performed demonstrations on the Knoff-Hoff Show, a very successful German T.V. science program. The goal of The Physics Force is to show students and the public Science is Fun, Science is Interesting, and Science is Understandable. By all measures we have available, we are extremely successful in reaching our goals. In the last three year cycle of our University support almost 100,000 residents of Minnesota (or about 2% of the total population) saw a Physics Force performance; it appears we will surpass those numbers in the present cycle.

    Motivation: Novel approaches are needed for discovery of targeted therapies for non-small-cell lung cancer (NSCLC) that are specific to certain patients. Whole genome RNAi screening of lung cancer cell lines provides an ideal source for determining candidate drug targets. Results: Unsupervised learning algorithms uncovered patterns of differential vulnerability across lung cancer cell lines to loss of functionally related genes. Such genetic vulnerabilities represent candidate targets for therapy and are found to be involved in splicing, translation and protein folding. In particular, many NSCLC cell lines were especially sensitive to the loss of components of the LSm2-8 protein complex or the CCT/TRiC chaperonin. Different vulnerabilities were also found for different cell line subgroups. Furthermore, the predicted vulnerability of a single adenocarcinoma cell line to loss of the Wnt pathway was experimentally validated with screening of small-molecule Wnt inhibitors against an extensive cell line panel.

    The funds from this grant were used to support observations and analysis with the International Ultraviolet Explorer (IUE) satellite telescope. The main area of scientific research concerned the variability analyses of ultraviolet spectra of Active Galactic Nuclei, primarily quasars, Seyfert galaxies, and BL Lacertae objects. The Colorado group included, at various times, the P.I. (J.M. Shull), Research Associate Dr. Rick Edelson, and graduate students Jon Saken, Elise Sachs, and Steve Penton. A portion of the work was also performed by CU undergraduate student Cheong-ming Fu. A major product of the effort was a database of all IUE spectra of active galactic nuclei. This database is being analyzed to obtain spectral indices, line fluxes, and continuum fluxes for over 500 AGN. As a by-product of this project, we implemented a new, improved technique of spectral extraction of IUE spectra, which has been used in several AGN-WATCH campaigns (on the Seyfert galaxy NGC 4151 and on the BL Lac object PKS 2155-304).

    The Space Engineering program at Utah State University has developed a small satellite, known as USUSat, under funding from AFOSR, AFRL, NASA and Utah State University's Space Dynamics Laboratory. This satellite was designed and significantly manufactured by students in the Mechanical and Aerospace Engineering and the Electrical and Computer Engineering Departments within the College of Engineering. USUSat is one of three spacecraft being designed for the Ionospheric Observation Nanosatellite Formation (ION- F). This formation comprises three 15 kg. spacecraft designed and built in cooperation by Utah State University, University of Washington, and Virginia Polytechnic Institute. The ION-F satellites are being designed and built by students at the three universities, with close coordination to insure compatibility for launch, deployment, and the formation flying mission. The JON-F mission is part of the U.S. Air Force Research Laboratory (AFRL) University Nanosatellite Program, which provides technology development and demonstrations for the TechSat2l Program. The University Nanosatellite Program involves 10 universities building nanosatellites for a launch in 2004 on two separate space shuttle missions. Additional support for the formation flying demonstration has been provided by NASA's Goddard Space Flight Center.

    After working with hundreds of leaders in a wide variety of organizations and in countries all over the globe, the authors found one very clear pattern: When it comes to meeting their leadership potential, many people unintentionally get in their own way. Five barriers in particular tend to keep promising managers from becoming exceptional leaders: People overemphasize personal goals, protect their public image, turn their competitors into two-dimensional enemies, go it alone instead of soliciting support and advice, and wait for permission to lead. Troy, a customer service manager, endangered his job and his company's reputation by focusing on protecting his position, not helping his team; when a trusted friend advised him to change his behavior, the results were striking. Anita's insistence on sticking to the tough personal she'd created for herself caused her to ignore the more intuitive part of the leadership equation, with disastrous results--until she let go of the need to appear invulnerable and reached out to another manager. Jon, a personal trainer who had virtually no experience with either youth development programs or urban life, opened a highly successful gym for inner-city kids at risk; he refused to be daunted by his lack of expertise and decided to simply "go for it." As these and other examples from the authors' research demonstrate, being a leader means making an active decision to lead. Only then will the workforce--and society--benefit from the enormous amount of talent currently sitting on the bench.

  4. Is There A Mechanics of Mind?

    NASA Astrophysics Data System (ADS)

    Jones, Robert

    2008-04-01

    In his book ``Extending Mechanics to Minds'' (Cambridge U. Press, 2006) Jon Doyle suggests that the human mind operates according to mechanical principles. Now in contemporary cognitive science operations in the cognitive or ``knowledge level'' are performed by lower level components of the program level. This decomposition continues from the program level down through the logic level, circuit level, and device level. Each level has its own components and each is described by its own laws of operation (Unified Theories of Cognition, Allen Newell, Harvard U. Press, 1990). The circuit and device levels could just as easily by fabricated out of mechanical elements such as linkage differentials and racks and pinions (Mechanisms and Dynamics of Machinery, Mabie and Ocvirk, John Wiley and Sons, 1975, ch. 8). These mechanisms would then be exactly those governed by the mechanical principles that Doyle focuses on. But Doyle's mistake is to apply the same laws to the cognitive level. Rather, I believe, the cognitive level is best described by operations like knowledge base search, analogy, classification, compression, etc. (R. Jones, Trans. of the Kansas Acad. of Sci., vol. 109, no. 3/4, pg 159, 2006).

    Fraud can be present in some scientific medical publications; however, the magnitude of this situation is unknown. One of the associated factors for this transgression of the good practice of investigation is the need to publish and obtain recognition and benefits, regardless of the means. The deliberate fabrication and falsification of data, plagiarism and duplication of publications are some of the scientific misconducts. Many cases of fraud in publications are known, and they have reached public opinion and have been a matter of legal sanctions (the names of Woo Suk Hwang, Jon Sudbo, Joachim Blodt, Robert Slutsky, and William Summerlin reminds us a few known cases). In the last decades, national and international regulatory organisms have been created in order to intervene against this scientific misconduct. Currently, we can rely on several effective software programs, whose function is to detect plagiarism and falsification of data. The prevention of scientific misconduct through information and education of the investigators could lead to the decrease of the presence of this problem, which damages scientific credibility and put at risk the patient's safety.

    From 1979 until his retirement from the project in 2001, Jon Galehouse of San Francisco State University (SFSU) and many student research assistants measured creep (aseismic slip) rates on these faults. The creep measurement project, which was initiated by Galehouse, continued through the Geosciences Department at SFSU from 2001-2006 under the direction of Karen Grove and John Caskey (Grove and Caskey, 2005) and since 2006 under Caskey (2007). Forrest McFarland has managed most of the technical and logistical project operations, as well as data processing and compilation since 2001. Data from 2001-2007 are found in McFarland and others (2007). From 2009 onward, we have released the raw data annually using this report (OF2009-1119) as a permanent publication link, while publishing more detailed analyses of these data in the scientific literature, such as Lienkaemper and others (2014a). We maintain a project Web site (http://funnel.sfsu.edu/creep/) that includes the following information: project description, project personnel, creep characteristics and measurement, map of creep-measurement sites, creep-measurement site information, and links to data plots for each measurement site. Our most current, annually updated results are, therefore, accessible to the scientific community and to the general public. Information about the project can currently be requested by the public by an email link (fltcreep@sfsu.edu) found on our project Web site.

    On October 31st at 4:00 pm in Panofsky Auditorium SLAC’s Colloquium Series will present the exceptional Oscar-nominated documentary The Day After Trinity. The film offers invaluable insight into historic events which have forever changed the face of our world – this screening should not to be missed. After witnessing the tremendous destructive power of the atomic bomb, J. Robert Oppenheimer declared “I have become death”. Still topically relevant a quarter of a century since its release, Director Jon Else’s documentary uses interviews, archival footage, and narration to reveal the internal landscape of the man whose leadership at Los Alamos, New Mexico, defined the rise of the Manhattan Project and the beginning of the Atomic Age. The Day After Trinity traces the unexpected path of Oppenheimer’s career - from his formation of the Los Alamos colony and the first successful atomic bomb detonation at the Trinity test site in 1945, to his final years spent branded as a security risk and excluded from the atomic energy research he pioneered due to his opposition to the development of the Hydrogen bomb.

  8. Call of the wild: the negative tendency in the nature religions of American youth.

    Kramp, Joseph M

    2015-02-01

    The author argues that the paucity of options for sanctioned rebellion in contemporary American society drive an ever-increasing number of idealistic youth in search of isolation in nature, where they construct what the author here calls "nature religions." These worldviews focus on purification of falsehood, ritualized through enduring extreme physical pain, social isolation, and extreme weather conditions in hopes of experiencing reality more authentically. The author argues that unemployment, limited vocational options, and the homogenization of American society are among the major catalysts for this ever-expanding breed of seekers, each of whom struggles with a negative tendency (a theoretical term created by Erik Erikson). Furthermore, the author argues that the emphasis in the nature religions on connection to nature is constructed to compensate for the lack of community and sense of human connectedness in contemporary American society. A representative case study from Jon Krakauer's (Into the wild; Doubleday, New York, 1996) Into the Wild is presented to illuminate and justify the argument made by the author for more institutionally housed options for sanctioned, licit rebellion to manage the negative tendency.

We Assisted Jon Nadler from Richland Community College in assembling and operating a table-top nuclear fusion reactor. We successfully demonstrated neutron production in a deuterium plasma. Pryor also obtained basic spectroscopic information on the atomic and molecular emissions in the plasma. The second project consisted of the completion of a paper on a novel propulsion concept (due to Tom Meyer of Colorado, the first author): a laser sail that bounces light back to the laser source. Recycling the photons from source to sail perhaps 100-1000 times dramatically improves the energy efficiency of this system, which may become very important for high-velocity missions in the future. Lastly, we compiled a very basic inventory of solar system propellant resources, their locations, and their accessibility. This initial inventory concentrates on sunlight availability, water availability, and the difficulty (delta-velocity requirement and radiation environment) in getting there.

  12. Commentary on muscle dysmorphia as an addiction: A response to Grant (2015) and Nieuwoudt (2015)

    Background Following the publication of our paper ‘Muscle Dysmorphia: Could it be classified as an addiction to body image?’ in the Journal of Behavioral Addictions, two commentaries by Jon Grant and Johanna Nieuwoudt were published in response to our paper. Method Using the ‘addiction components model’, our main contention is that muscle dysmorphia (MD) actually comprises a number of different actions and behaviors and that the actual addictive activity is the maintaining of body image via a number of different activities such as bodybuilding, exercise, eating certain foods, taking specific drugs (e.g., anabolic steroids), shopping for certain foods, food supplements, and purchase or use of physical exercise accessories. This paper briefly responds to these two commentaries. Results While our hypothesized specifics relating to each addiction component sometimes lack empirical support (as noted explicitly by both Nieuwoudt and Grant), we still believe that our main thesis (that almost all the thoughts and behaviors of those with MD revolve around the maintenance of body image) is something that could be empirically tested in future research by those who already work in the area. Conclusions We hope that the ‘Addiction to Body Image’ model we proposed provides a new framework for carrying out work in both empirical and clinical settings. The idea that MD could potentially be classed as an addiction cannot be negated on theoretical grounds as many people in the addiction field are turning their attention to research in new areas of behavioral addiction.

    Juergens, Richard C.

    2014-12-01

    The lens design problem for the 2014 IODC is to design a 100 mm focal length lens in which all the components of the lens can be manufactured from ten Schott N-BK7 lens blanks 100 mm in diameter x 30 mm thick. The lens is used monochromatically at 587.56 nm. The goal of the problem is to maximize the product of the entrance pupil diameter and the semi-field of view while holding the RMS wavefront error to <= 0.070 wave within the field of view. There were 45 entries from 13 different countries. Four different commercial lens design programs were used, along with six custom, in-house programs. The number of lens elements in the entries ranged from 10 to 52. The winning entry from Jon Ehrmann had 25 lens elements, and had an entrance pupil diameter of 33.9 mm and a semi-field of view of 62.5° for a merit function product of 2,119.

  15. Call of the wild: the negative tendency in the nature religions of American youth.

    Kramp, Joseph M

    2015-02-01

    The author argues that the paucity of options for sanctioned rebellion in contemporary American society drive an ever-increasing number of idealistic youth in search of isolation in nature, where they construct what the author here calls "nature religions." These worldviews focus on purification of falsehood, ritualized through enduring extreme physical pain, social isolation, and extreme weather conditions in hopes of experiencing reality more authentically. The author argues that unemployment, limited vocational options, and the homogenization of American society are among the major catalysts for this ever-expanding breed of seekers, each of whom struggles with a negative tendency (a theoretical term created by Erik Erikson). Furthermore, the author argues that the emphasis in the nature religions on connection to nature is constructed to compensate for the lack of community and sense of human connectedness in contemporary American society. A representative case study from Jon Krakauer's (Into the wild; Doubleday, New York, 1996) Into the Wild is presented to illuminate and justify the argument made by the author for more institutionally housed options for sanctioned, licit rebellion to manage the negative tendency.

    Protein kinase C (PKC) isoforms have been implicated in several platelet functional responses, but the contribution of individual isoforms has not been thoroughly evaluated. Novel PKC isoform PKC-theta is activated by glycoprotein VI (GPVI) and protease-activated receptor (PAR) agonists, but not by adenosine diphosphate. In human platelets, PKC-theta-selective antagonistic (RACK; receptor for activated C kinase) peptide significantly inhibited GPVI and PAR-induced aggregation, dense and alpha-granule secretion at low agonist concentrations. Consistently, in murine platelets lacking PKC-theta, platelet aggregation and secretion were also impaired. PKC-mediated phosphorylation of tSNARE protein syntaxin-4 was strongly reduced in human platelets pretreated with PKC-theta RACK peptide, which may contribute to the lower levels of granule secretion when PKC-theta function is lost. Furthermore, the level of JON/A binding to activated alpha(IIb)beta(3) receptor was also significantly decreased in PKC-theta(-/-) mice compared with wild-type littermates. PKC-theta(-/-) murine platelets showed significantly lower agonist-induced thromboxane A(2) (TXA(2)) release through reduced extracellular signal-regulated kinase phosphorylation. Finally, PKC-theta(-/-) mice displayed unstable thrombus formation and prolonged arterial occlusion in the FeCl(3) in vivo thrombosis model compared with wild-type mice. In conclusion, PKC-theta isoform plays a significant role in platelet functional responses downstream of PAR and GPVI receptors. PMID:19164598

  17. Implementing reproducible research using the Madagascar open-source software package

    Reproducible research is a concept pioneered by Jon Claerbout. It refers to the discipline of attaching software code and data to scientific publications, which enables the reader to reproduce, verify, and extend published computational experiments. The Madagascar open-source software package provides an example of implementing the reproducible research discipline in geophysical publications. The package contains not only software tools for making geophysical computations but also research papers complete with links to data and reproducible data-analysis workflows. When researchers discover a research paper published on the Madagascar website and install Madagascar, they are able to follow the links and replicate all computations to verify the published computational results. Of course, reproducibility is not the goal in itself. The goal is to be able to extend previously published research by, for example, trying new computations on previously used data or previously used computations on new data. The Madagscar collection currently contains about 150 research papers and book chapters and about 900 reproducible scripts. More than 80 people from different organizations around the world have contributed to the development. This experience shows that, instead of being the responsibility of an individual author, computational reproducibility can become the responsibility of open-source scientific-software communities. Our experience shows how a dedicated community effort can keep a body of computational research alive by actively maintaining its reproducibility.

  18. AGU Committee Update: Recent activities of NG Technical Committee

    NASA Astrophysics Data System (ADS)

    Rundle, John B.

    Beginning this year, the AGU has adopted a series of new policies designed to highlight the interdisciplinary aspects of the Union. As part of these new policies, members will soon be able to affiliate with the AGU Technical Committees, including the Nonlinear Geophysics (NG) Committee. In addition, the Technical Committees are now able to sponsor or co-sponsor technical sessions at both the Spring and Fall annual meetings, as well as make awards for best research and papers, and sponsor nominations for AGU Fellows and Union-wide awards.A website for the NG committee, with descriptions of the committee's activities and other functions, can be found via a link from the main AGU website, which is maintained by Jon Pelletier (University of Arizona). An AGU/NG listserver is maintained by the AGU staff liaison to NG, Dan Moore (DMoore@agu.org). AGU members wishing to be apprised of NG committee activities by inclusion in the listserv should either sign up through the NG web site, or send email to Dan Moore. As described, the NG committee can nominate an AGU member for election to AGU Fellow status. Don Turcotte (Cornell University) chairs the NG subcommittee on Fellow nominations.

  19. Mindfulness meditation: do-it-yourself medicalization of every moment.

    2014-04-01

    This paper examines mindfulness as a popular and paradigmatic alternative healing practice within the context of contemporary medicalization trends. In recognition of the increasingly influential role popular media play in shaping ideas about illness and healing, what follows is a discursive analysis of bestselling mindfulness meditation self-help books and audio recordings by Jon Kabat-Zinn. The central and contradictory elements of this do-it-yourself healing practice as presented in these materials are best understood as aligned with medicalization trends for three principal reasons. First, mindfulness represents a significant expansion in the definition of disease beyond that advanced by mainstream medicine. Second, its etiological model intensifies the need for therapeutic surveillance and intervention. Third, by defining healing as a never-ending process, it permanently locates individuals within a disease-therapy cycle. In sum, the definition, cause, and treatment of disease as articulated by popular mindfulness resources expands the terrain of experiences and problems that are mediated by medical concepts. The case of mindfulness is a potent illustration of the changing character of medicalization itself. PMID:24565760

    Call for Papers: Optical Ethernet The Journal of Optical Networking (JON) is soliciting papers for a second feature issue on Optical Ethernet. Ethernet has evolved from a LAN technology connecting desktop computers to a universal broadband network interface. It is not only the vehicle for local data connectivity but also the standard interface for next-generation network equipment such as video servers and IP telephony. High-speed Ethernet has been increasingly assuming the volume of backbone network traffic from SONET/SDH-based circuit applications. It is clear that IP has become the universal network protocol for future converged networks, and Ethernet is becoming the ubiquitous link layer for connectivity. Network operators have been offering Ethernet services for several years. Problems and new requirements in Ethernet service offerings have been captured through previous experience. New study groups and standards bodies have been formed to address these problems. This feature issue aims at reviewing and updating the new developments and R&D efforts of high-speed Ethernet in recent years, especially those related to the field of optical networking.
