  1. Seeing Double

    Pesic, Peter

    2003-10-01

    The separateness and connection of individuals is perhaps the central question of human life: What, exactly, is my individuality? To what degree is it unique? To what degree can it be shared, and how? To the many philosophical and literary speculations about these topics over time, modern science has added the curious twist of quantum theory, which requires that the elementary particles of which everything consists have no individuality at all. All aspects of chemistry depend on this lack of individuality, as do many branches of physics. From where, then, does our individuality come? In Seeing Double, Peter Pesic invites readers to explore this intriguing set of questions. He draws on literary and historical examples that open the mind (from Homer to Martin Guerre to Kafka), philosophical analyses that have helped to make our thinking and speech more precise, and scientific work that has enabled us to characterize the phenomena of nature. Though he does not try to be all-inclusive, Pesic presents a broad range of ideas, building toward a specific point of view: that the crux of modern quantum theory is its clash with our ordinary concept of individuality. This represents a departure from the usual understanding of quantum theory. Pesic argues that what is bizarre about quantum theory becomes more intelligible as we reconsider what we mean by individuality and identity in ordinary experience. In turn, quantum identity opens a new perspective on us. Peter Pesic is a Tutor and Musician-in-Residence at St. John's College, Santa Fe, New Mexico. He has a Ph.D. in physics from Stanford University.

  2. Seeing Red

    This New Horizons image of Jupiter's volcanic moon Io was taken at 13:05 Universal Time during the spacecraft's Jupiter flyby on February 28, 2007. It shows the reddish color of the deposits from the giant volcanic eruption at the volcano Tvashtar, near the top of the sunlit crescent, as well as the bluish plume itself and the orange glow of the hot lava at its source. The relatively unprocessed image on the left provides the best view of the volcanic glow and the plume deposits, while the version on the right has been brightened to show the much fainter plume, and the Jupiter-lit night side of Io.

    New Horizons' color imaging of Io's sunlit side was generally overexposed because the spacecraft's color camera, the super-sensitive Multispectral Visible Imaging Camera (MVIC), was designed for the much dimmer illumination at Pluto. However, two of MVIC's four color filters, the blue and 'methane' filter (a special filter designed to map methane frost on the surface of Pluto at an infrared wavelength of 0.89 microns), are less sensitive than the others, and thus obtained some well-exposed views of the surface when illumination conditions were favorable. Because only two color filters are used, rather than the usual three, and because one filter uses infrared light, the color is only a rough approximation to what the human eye would see.

    The red color of the Tvashtar plume fallout is typical of Io's largest volcanic plumes, including the previous eruption of Tvashtar seen by the Galileo and Cassini spacecraft in 2000, and the long-lived Pele plume on the opposite side of Io. The color likely results from the creation of reddish three-atom and four-atom sulfur molecules (S3 and S4) from plume gases rich in two-atom sulfur molecules (S2 After a few months or years, the S3 and S4 molecules recombine into the more stable and familiar yellowish form of sulfur consisting of eight-atom molecules (S8), so these red deposits are only seen around recently-active Io

    Geoscience disciplines are filled with visual displays of data. From the first cave drawings to remote imaging of our Planet, visual displays of information have been used to understand and interpret our discipline. As practitioners of the art, visuals comprise the core around which we write scholarly articles, teach our students and make every day decisions. The effectiveness of visual communication, however, varies greatly. For many visual displays, a significant amount of prior knowledge is needed to understand and interpret various representations. If this is missing, key components of communication fail. One common example is the use of animations to explain high density and typically complex data. Do animations effectively convey information, simply "wow an audience" or do they confuse the subject by using unfamiliar forms and representations? Prior knowledge impacts the information derived from visuals and when communicating with non-experts this factor is exacerbated. For example, in an advanced geology course fractures in a rock are viewed by petroleum engineers as conduits for fluid migration while geoscience students 'see' the minerals lining the fracture. In contrast, a lay audience might view these images as abstract art. Without specific and direct accompanying verbal or written communication such an image is viewed radically differently by disparate audiences. Experts and non-experts do not 'see' equivalent images. Each visual must be carefully constructed with it's communication task in mind. To enhance learning and communication at all levels by visual displays of data requires that we teach visual literacy as a portion of our curricula. As we move from one form of visual representation to another, our mental images are expanded as is our ability to see and interpret new visual forms thus promoting life-long learning. Visual literacy is key to communication in our visually rich discipline. What do you see?

    Rome surrounds the State of the Vatican City which provides the territorial base of the Holy See, i.e. the central government of the Roman Catholic Church. The population consists of 1000 people mostly of Italian or Swiss nationality, while the work force includes 4000 individuals. Even though Italian is commonly used, official acts of the Holy See are written in Latin. When Italy unified in 1861, the Kingdom of Italy ruled over most of the Papal States, except Rome and its environs, until 1870 at which time Rome was forced to join the Kingdom. On February 11, 1929, the Italian Government and the Holy See signed an agreement recognizing the independence and sovereignty of the Holy See and creating the State of the Vatican City, fixing relations between the church and the government, and providing the Holy See compensation for its financial losses. Pope John Paul II, the first nonItalian Pope in almost 5 centuries and a Pole, is the present leader of the Legislative, executive, and judicial branches of the Holy See and the State. The Roman Curia and its staff, the Papal Civil Service, assists the Pope in ruling the Holy See. The Curia, directed by the Secretariat of State, includes 9 Congregations, 3 Tribunals, 12 Pontifical Councils, and offices that handle church affairs at the highest level. Since the 4th century, the Holy See has had diplomatic relations with other sovereign states and continues so today. Presently, it has nearly 80 permanent diplomatic missions in other countries and carries on diplomatic relations with 119 nations. In addition, the HOly See participates in diplomatic activities with international organizations which include the UN in New York and Geneva, UNESCO, the European Economic Community, and other related organizations. The United States has had relations with the Papal States form 1797-1870. The US and the Holy See reestablished diplomatic relations on January 10, 1984. PMID:12178005

    Useful, well-demonstrated, well-vetted ideas in clinical practice, disease management, health care management, ideas that would save lives, save money, and make life better for the patient, are sometimes simply ignored, dismissed as radical, as completely unfounded, dangerous, and without merit. Why are new ideas so slow to spread in medicine and health care? Because believing is seeing. We do not look for something we don't believe in. In fact, we do not even see a thing if we don't believe in it. We have dedicated ourselves so powerfully to medicine, to health care as we know it, that we often do not even see any alternatives. A combination of factors makes it likely that, in the coming decade or two, we will change almost everything that is fundamental about health care and medicine. In a time of such rapid change, we desperately need to root out and question our deep assumptions and beliefs, to get off the tracks laid down by training and experience and ask questions we have never asked before.

    The unique ultraviolet vision of NASA's Galaxy Evolution Explorer reveals, for the first time, dwarf galaxies forming out of nothing more than pristine gas likely leftover from the early universe. Dwarf galaxies are relatively small collections of stars that often orbit around larger galaxies like our Milky Way.

    The forming dwarf galaxies shine in the far ultraviolet spectrum, rendered as blue in the call-out on the right hand side of this image. Near ultraviolet light, also obtained by the Galaxy Evolution Explorer, is displayed in green, and visible light from the blue part of the spectrum here is represented by red. The clumps (in circles) are distinctively blue, indicating they are primarily detected in far ultraviolet light.

    The faint blue overlay traces the outline of the Leo Ring, a huge cloud of hydrogen and helium that orbits around two massive galaxies in the constellation Leo (left panel). The cloud is thought likely to be a primordial object, an ancient remnant of material that has remained relatively unchanged since the very earliest days of the universe. Identified about 25 years ago by radio waves, the ring cannot be seen in visible light.

    Only a portion of the Leo Ring has been imaged in the ultraviolet, but this section contains the telltale ultraviolet signature of recent massive star formation within this ring of pristine gas. Astronomers have previously only seen dwarf galaxies form out of gas that has already been cycled through a galaxy and enriched with metals elements heavier than helium produced as stars evolve.

    Alas, scientists can finally see with their eyes what they have only seen in their heads. Researchers from Boston University's Center for Space Physics, The Aerospace Corporation, and the Los Alamos National Laboratory have produced the first movies of particle activity in the near-Earth space environment. Looking down on much of Earth's magnetosphere from the polar orbit of NASA's POLAR spacecraft, the researchers have compiled high-resolution, sequential images of space weather.Relying primarily on POLAR's imaging proton spectrometer (IPS), the research team amassed data on energetic neutral atoms (ENAs). These atoms are created when cold, neutral gases of the atmosphere interact with the energetic, charged particles trapped in Earth's radiation belts. From analyses of ENAs, the team was able to generate images of geomagnetic activity in the shell around Earth.

    2002-10-01

    A two-element interferometer for monitoring atmospheric phase fluctuations (radio seeing) is presented; this uses the unmodulated beacon signal at 11.715 GHz from a geostationary satellite. The system measures phase differences on the signal received by two small antennas separated by 50 m. The system incorporates the best features from previous designs: a heterodyne phase-lock receiver and an IQ demodulator system. Phase fluctuations measured at this frequency may be extrapolated to millimetric and submillimetric wavelengths since the atmosphere is not dispersive at these frequencies. The instrument has been tested at the Observatory San Pedro Martir (Mexico) at 2800 m above sea level. The final destination of the instrument is Cerro la Negra (Mexico), where the Large Millimeter Telescope is under construction, at an altitude of 4600 m.

    Methods to correct for atmospheric degradation of imagery and improve the "seeing" of a telescope are well known in astronomy but, to date, have rarely been applied to more earthly matters such as surveillance. The intrinsically more complicated visual fields, the dominance of low-altitude distortion effects, the requirement to process large volumes of data in near real-time, the inability to pre-select ideal sites and the desirability of ruggedness and portability all combine to pose a significant challenge. Field Programmable Gate Array (FPGA) technology has advanced to the point where modern devices contain hundreds of thousands of logic gates, multiple "hard" processors and multi-gigabit serial communication links. Such devices present an ideal platform to tackle the demands of surveillance image processing. We report a rugged, lightweight system which allows multiple FPGA "modules" to be added together in order to quickly and easily reallocate computing resources. The devices communicate via 2.5Gbps serial links and process image data in a streaming fashion, reducing as much data as possible on-the-fly in order to present a minimised load to storage and/or communication devices. To maximise the benefit of such a system we have devised an open protocol for FPGA-based image processing called "OpenStream". This allows image processing cores to be quickly and easily added into or removed from the data stream and harnesses the benefits of code-reuse and standardisation. It further allows image processing tasks to be easily partitioned across multiple, heterogeneous FPGA domains and permits a designer the flexibility to allocate cores to the most appropriate FPGA. OpenStream is the infrastructure to facilitate rapid, graphical, development of FPGA based image processing algorithms especially when they must be partitioned across multiple FPGAs. Ultimately it will provide a means to automatically allocate and connect resources across FPGA domains in a manner analogous

    Evaluation of seeing effects on the light curve of a stellar occultation by the moon. Some theoretical studies of Fried (1966) and Hulett (1967) on the linear size of the downward-looking seeing disk are cited, showing that the seeing blur amounts to a few centimeters for a star in the zenith and that the linear blur must grow approximately as (sec z) to the 3/2 power. For most observations the seeing blur will not exceed 8 to 10 cm. The limitation on angular resolution imposed by this seeing effect is calculated.

    '. The Chameleon I complex nebula is one beautiful example. When making observations in the near-infrared, art becomes science. Near-infrared radiation can indeed propagate much farther into the cloud than visible light and the maps of scattered light can be used to measure the mass of the material inside the cloud. To put this method to the test and use it for the first time for a quantitative estimation of the distribution of mass within a cloud, the astronomers who made the original suggestion, together with Kalevi Mattila, made observations in the near-infrared of a filament in the Corona Australis cloud [2] . The observations were made in August 2006 with the SOFI instrument on ESO's New Technology Telescope at La Silla, in the Chilean Atacama Desert. The filament was observed for about 21 hours. Their observations confirm that the scattering method is providing results that are as reliable as the use of background stars while providing much more detail. "We can now obtain very high resolution images of dark clouds and so better study their internal structure and dynamics," says Juvela. "Not only is the level of details in the resulting map no longer dependent on the distribution of background stars, but we have also shown that where the density of the cloud becomes too high to be able to see any background stars, the new method can still be applied." "The presented method and the confirmation of its feasibility will enable a wide range of studies into the interstellar medium and star formation within the Milky Way and even other galaxies," says co-author Mattila. "This is an important result because, with current and planned near-infrared instruments, large cloud areas can be mapped with high resolution," adds Pelkonen. "For example, the VIRCAM instrument on ESO's soon-to-come VISTA telescope has a field of view hundreds of times larger than SOFI. Using our method, it will prove amazingly powerful for the study of stellar nurseries."

    The seeing calculation and its evolution during the night is a key point for the operation of telescopes and adaptive optics systems. Currently, there are various instruments able to measure the seeing, for example, the DIMM (differential image motion monitor) and the MASS (multi aperture scintillation sensor). This paper describes a new tool for the local ground layer seeing measurement. In particular, we want to derive the Fried parameter r0 through a laser beam horizontal propagation. This is a new method for the experimental study of low-altitude atmospheric turbulence. Finally, we sketch an experimental setup for the Asiago Ekar Observatory and its possible applications.

  20. Estimating dome seeing for LSST

    Sebag, Jacques; Vogiatzis, Konstantinos

    2014-08-01

    Begin Dome seeing is a critical effect influencing the optical performance of ground based telescopes. A previously reported combination of Computational Fluid Dynamics (CFD) and optical simulations to model dome seeing was implemented for the latest LSST enclosure geometry. To this end, high spatial resolution thermal unsteady CFD simulations were performed for three different telescope zenith angles and four azimuth angles. These simulations generate time records of refractive index values along the optical path, which are post-processed to estimate the image degradation due to dome seeing. This method allows us to derive the distribution of seeing contribution along the different optical path segments that composed the overall light path between the entrance of the dome up to the LSST science camera. These results are used to recognize potential problems and to guide the observatory design. In this paper, the modeling estimates are reviewed and assessed relative to the corresponding performance allocation, and combined with other simulator outputs to model the dome seeing impact during LSST operations.

    Institute of Astronomy, University of Tokyo is now planning to build a 6.5-m optical-infrared telescope in Atacama, Chile. This project is called "Univ. Tokyo Atacama Observatory (TAO)", and the site evaluation is now under way. As a part of this evaluation process, we started an investigation to compare the astronomical seeing at Atacama with that at Mauna Kea. Here, we report preliminary results of seeing measurements at several sites in Atacama, carried out on October 2003. In order to separate the temporal and site-to-site variation of the seeing, we used two sets of Differential Image Motion Monitors (DIMMs), each of which has two pairs of 7.4 cm sub-apertures with 20.5 cm separation. Three sites were investigated; the point near the TAO weather station (4,950m), the summit of Cello Chico (5,150m) and the point at 5,430m altitude on Cello Toco. Simultaneous measurements were carried out for three half nights out of four half nights measurements. Although the amount of our data is very limited, the results suggest following: 1) Seeing becomes better and more stable as time passing to midnight (eg. From 0."7 to 0."4 at V-band). 2) Higher altitude sites show better seeing than lower altitude sites.

In the article, Table 2 contained a production-related formatting error. Values from column 11 onward were shifted upwards in the table. All versions of this article have been corrected.] Despite an increased interest in the phenomenon of stigma in organizations, we know very little about the interactions between those who are stigmatized and those who stigmatize them. Integrating both the perceptions of the stigmatized worker and the stigmatizing customer into one model, the present study addresses this gap. It examines the role of stereotypes held by customers of stigmatized organizations and metastereotypes held by the stigmatized workers themselves (i.e., their shared beliefs of the stereotypes customers associate with them) in frontline exchanges. To do so, data regarding frontline workers (vendors) of homeless-advocate newspapers from 3 different sources (vendors, customers, trained observers) were gathered. Multilevel path-analytic hypotheses tests reveal (a) how frontline workers' prototypicality for a stigmatized organization renders salient a stigma within frontline interactions and (b) how stereotypes by customers and metastereotypes by frontline workers interact with each other in such contacts. The results support a hypothesized interaction between frontline workers' metastereotypes and customers' stereotypes-what we call the "stigma magnification effect". The study also derives important practical implications by linking stigma to frontline workers' discretionary financial gains. (PsycINFO Database Record PMID:26653529

More recent Cassini high-resolution imaging of the region over a wide range of illumination geometry reveals a systematic change in the appearance of the circular albedo features as the phase angle decreases from α=124° to α=31° -- the circular albedo features that are so clearly visible at large phase angles are completely masked at small phase angles. The decrease in the albedo contrast with decreasing phase angle is dramatic: The average albedo contrast between the circular P1 and P2 features diminishes from 27±3% at phase α=124° to only 1.3±0.2% at α=31°. A likely explanation for this photometric behavior is that it reveals a top layer of frost or snow that scatters light strongly at relatively small phase angles, but which becomes more transparent as phase angles increase allowing Cassini to see through to underlying features. It is also possible that the changing photometric contrasts arise from terrain-dependent differences in regolith properties like surface roughness or regolith grain-size.

    This is a course on SEE Test Plan development. It is an introductory discussion of the items that go into planning an SEE test that should complement the SEE test methodology used. Material will only cover heavy ion SEE testing and not proton, LASER, or other though many of the discussed items may be applicable. While standards and guidelines for how-to perform single event effects (SEE) testing have existed almost since the first cyclotron testing, guidance on the development of SEE test plans has not been as easy to find. In this section of the short course, we attempt to rectify this lack. We consider the approach outlined here as a "living" document: mission specific constraints and new technology related issues always need to be taken into account. We note that we will use the term "test planning" in the context of those items being included in a test plan.

    The present study aims to reveal some facts concerning first language ([Formula: see text] and second language ([Formula: see text] spoken-word processing in unbalanced proficient bilinguals using behavioral measures. The intention here is to examine the effects of auditory repetition word priming and semantic priming in first and second languages of these bilinguals. The other goal is to explore the effects of attention manipulation on implicit retrieval of perceptual and conceptual properties of spoken [Formula: see text] and [Formula: see text] words. In so doing, the participants performed auditory word priming and semantic priming as memory tests in their [Formula: see text] and [Formula: see text]. In a half of the trials of each experiment, they carried out the memory test while simultaneously performing a secondary task in visual modality. The results revealed that effects of auditory word priming and semantic priming were present when participants processed [Formula: see text] and [Formula: see text] words in full attention condition. Attention manipulation could reduce priming magnitude in both experiments in [Formula: see text]. Moreover, [Formula: see text] word retrieval increases the reaction times and reduces accuracy on the simultaneous secondary task to protect its own accuracy and speed. PMID:26643309

    2003-01-01

    This paper begins by discussing the potential for scaling down transistors and other components to fit more of them on chips in order to increasing computer processing speed. It also addresses technical challenges to further scaling. Components have been scaled down enough to allow single particles to have an effect, known as a Single Event Effect (SEE). This paper explores the relationship between scaling and the following SEEs: Single Event Upsets (SEU) on DRAMs and SRAMs, Latch-up, Snap-back, Single Event Burnout (SEB), Single Event Gate Rupture (SEGR), and Ion-induced soft breakdown (SBD).

    The need to preserve works and NASA documented articles is done via the collection of various Space Environments and Effects (SEE) related articles. (SEE) contains and lists the various projects that are ongoing, or have been conducted with the help of NASA. The goal of the (SEE) program is to make publicly available the environment technologies that are required to design, manufacture and operate reliable, cost-effective spacecraft for the government and commercial sectors. Of the many projects contained within the (SEE) program the Lunar-E Library and Spacecraft Materials Selector (SMS) have been selected for a more user friendly means to make the tools easily available to the public. This information which is still available required a person or entity to request access from a point of contact at NASA and wait for the requested bundled software DVD via postal service. Redesigning the material presentation and availability has been mapped to a single step process with faster turnaround time via Materials and Processes Technical Information System (MAPTIS) database. This process requires users to register and be verified in order to gain access to the information contained within. Aiding in the progression of making the software tools/documents available required a combination of specialized in-house data gathering software tools and software archeology.

  6. Multiple-Aperture Based Solar Seeing Profiler

    Zhao, Gang; Ren, Deqing

    2015-08-01

    Characterization of daytime atmospheric turbulence profile up to 30 km above the telescope is crucial for designs and performance estimations of solar Multi-Conjugate Adaptive Optics (MCAO) systems. To measure seeing profiles up to 30km, we introduce the Multiple Aperture Seeing Profiler (MASP). It bases on the principle of S-DIMM+ and consists of two portable small telescopes similar to SHABAR. Thus the MASP take the advantages of both S-DIMM+ and SHABAR. It is portable and can be used without big telescope, while it has ability to measure turbulence profile up to 30km. Numerical simulations are carried out to evaluate the performance of MASP. We find that for one layer case, MASP can retrieve the seeing with error ~5% using 800 frames of WFS data, which is quite similar with the results of a telescope with diameter of 1120mm. We also simulate profiles with four turbulence layers, and find that our MASP can well retrieve the strengths and heights of the four turbulence layers. Since previous measurements at BBSO showed that daytime turbulence profile typically consists of four layers, MASP we introduced is sufficient for actual seeing measurement.

  8. Seeing the Real Atomic Correlation in Matter

    SciTech Connect

    Egami, Takeshi

    2006-02-01

    Bragg's law is an ultimate magic, because it reduces the positions of 10(23) atoms to just a few numbers. This, of course, is a lucky consequence of translational symmetry. Unfortunately, we are not always lucky with many materials that are important today, including ourselves (biological matter), since they (and we) are not crystalline, or only poorly crystalline. But it is possible to see, more or less directly, the real atomic correlations in these disordered matters by using the method of atomic pair-density function (PDF) analysis using neutron or x-ray scattering. Due to advances in instrumentation we now can determine the PDF up to 20 nm, and see even the dynamics of correlation by the dynamic PDF method. This talk will address some examples of this approach facilitates understanding of complex matter, and where the field may be heading.

    2015-09-01

    Humans often strategically manipulate the informational access of others to their own advantage. Although chimpanzees know what others can and cannot see, it is unclear whether they can strategically manipulate others' visual access. In this study, chimpanzees were given the opportunity to save food for themselves by concealing it from a human competitor and also to get more food for themselves by revealing it to a human cooperator. When knowing that a competitor was approaching, chimpanzees kept more food hidden (left it covered) than when expecting a cooperator to approach. When the experimenter was already at the location of the hidden food, they actively revealed less food to the competitor than to the cooperator. They did not actively hide food (cover up food in the open) from the competitor, however. Chimpanzees thus strategically manipulated what another could see in order to maximize their payoffs and showed their ability to plan for future situations. PMID:25964096

    Visible light constitutes only a very narrow part of the wide electromagnetic spectrum. This article outlines several reasons why the human eye can see only within this limited range. Solar emissions and low absorption in the atmosphere are determining causes, but not the only ones. The energy of chemical bonds, the optical properties of matter, black body emissions and the wave character of light cause further limitations, all of which have a remarkable congruence.

    Space environment group in JAXA has installed insturments to measure space environment on eleven satellites. In the last year, the biggest instrument called SEDA-AP (Space Environment Data Acquision equipment -Attached Paylod) was atteched to the palette of JEM (ISS). On the other hand, we have a web site, "Space Environment and Effects System(SEES)". This system consisits of four parts. First part is to provide data that were obtained from these insturments. There are 18 kinds of mesurments, for example, radiation, magnetic field and so on. In 1994, Anik E-1 and Anik E-2 were broken by solar storm and we could catch the abnormal data from our instrument. Second part is a warning system. Many Japanese satellites are working around the earth and they are always exposed to radioactivity in space. So we predict the the radiation data in two days and if the expected value is over the threshold of safety, we inform a warning massage to users who want to keep their satellites safe. And we also provide the warning massage for Japanese astronauts who stay at ISS. Third part is the tool of the space environment /satellite environment models. There are 12 kinds of environment models which are constructed from 90 space environment models, for example, radiation model, solar activity model and so on. If you register your infomation in the SEES web site, you can simulate space environment by using them. Fourth part is providing the 2D and 3D infomations of satellite's orvits. This show the satelllite's position on the world map at a paticular time. If you want to use this system, please visit our SEES page at (http://seesproxy.tksc.jaxa.jp/fw/dfw/SEES/index.html ).

    2015-09-01

    Characterization of day-time atmospheric turbulence profiles up to 30 km above the telescope is crucial for designs and performance estimations of future solar multiconjugate adaptive optics (MCAO) systems. Recently, the S-DIMM+ method has been successfully used to measure the vertical profile of turbulence. However, to measure profile up to 30 km employing the S-DIMM+ method, a telescope with a diameter of at least 1.0 m is needed, which restricts the usage of S-DIMM+, since large telescopes are scarce and their time is limited. To solve this problem, we introduce the multiple-aperture seeing profiler (MASP), which consists of two portable small telescopes instead of a single large aperture. Numerical simulations are carried out to evaluate the performance of MASP. We find that for one layer case, MASP can retrieve the seeing with error ~5% using 800 frames of wavefront sensor (WFS) data, which is quite similar to the results of a telescope with diameter of 1120 mm. We also simulate profiles with four turbulence layers, and find that our MASP can effectively retrieve the strengths and heights of the four turbulence layers. Since previous measurements at Big Bear Solar Observatory showed that day-time turbulence profile typically consists of four layers, the MASP we introduced is sufficient for actual seeing measurement.

  15. ``To See Cosmology in a Quetzal..."

    NASA Astrophysics Data System (ADS)

    Neuenschwander, D. E.; Finkenbinder, L.

    2002-05-01

    High in the Talamanca Mountains of Costa Rica, our university maintains a field station called the Quetzal Education Research Center (QERC), in cloud forest habit of the magnificent Resplendent Quetzal. At these latitudes, where every surface is alive, the astronomical realities that constrain life's options acquire an in-your-face immediacy. Three years ago we began team-teaching a general astrobiology course featuring a 10-day trip to the QERC and other Costa Rican sites, including the Arenal Volcano and Manuel Antonio National Park. This experience places the student smack in the middle of an environment that dramatically shows how stellar evolution provides the energy, materials, and timescale for biological evolution. For example, discussion of tidal forces occurs when we are up to our necks in the tide at Manuel Antonio's beaches; discussions of nuclear reactions that power the Sun are followed with extended forest hikes to see the light-gathering strategies of photosynthetic organisms; as an astronomical system, quetzal DNA is a ``metal," a product of nucleosynthesis. Our time in Costa Rica also features an astronomy education program for the residents of San Gerardo de Dota (in the rural valley where the QERC is located), with presentations at the local school and astronomy ``open house" evenings at the QERC. As one travels the country one also sees the rapid destruction of tropical forest biodiversity. We therefore encourage through astrobiology the formation of another kind of ``ecosystem:" the global network of young people who are valiantly confronting the challenges of environmental sustainability. Solutions to these problems must take into account economic, cultural, and political realities as well as scientific realities. The importance of seeing these immediate problems in terms of astronomical and biological evolution timescales forms another splendid motivation for the study of astrobiology.

  16. Monitoring Polaris and Seeing Conditions at PARI

    NASA Astrophysics Data System (ADS)

    Crawford, April

    2016-01-01

    Pisgah Astronomical Research Institute (PARI) was originally built by NASA to track and collect data from satellites. The location in the Pisgah National Forest was chosen due to the excellent ability of the surrounding mountains to block radio interference and light pollution. The PARI observatory has been monitoring Polaris for over 10 years and has amassed a large collection of images of the star and those surrounding it. While several telescopes have been used throughout the project, we are currently using a Omni XLT Series Celestron and an SBIG ST-8300M CCD camera with a 0.70 arcsecond/pixel ratio. The software is run on Windows, however, we will be making a switch to Linux and implementing a new program to control the camera. The new images, once converted to a usable format (ST10 to FITS), can be automatically fed into an in-house Java program to track the variability of the star and simultaneously determine the seeing conditions experienced on the campus. Since we have several years worth of data, the program will also be used to provide a history of variability and seeing conditions. We ultimately hope to be able to track the possible changes in variability of Polaris, as it's current location on the HR diagram is being studied. The data could also prove valuable for our on-site scientists and many visiting students to study on campus. We are also developing a relative scale for our seeing conditions, accompanied by FWHM measurements in arcseconds that will can be compared to those of surrounding observatories in mountainous areas.

    This paper describes the implementation of a hierarchical robot simulation which supports the design of robots with vision and mobility. A seeing robot applies a classification expert system for visual identification of laboratory objects. The visual data acquisition algorithm used by the robot vision system has been developed to exploit multiple viewing distances and perspectives. Several different simulations have been run testing the visual logic in a laboratory environment. Much work remains to integrate the vision system with the rest of the robot system.

  18. See around the corner using active imaging

    NASA Astrophysics Data System (ADS)

    Steinvall, Ove; Elmqvist, Magnus; Larsson, Håkan

    2011-11-01

    This paper investigates the prospects of "seeing around the corner" using active imaging. A monostatic active imaging system offers interesting capabilities in the presence of glossy reflecting objects. Examples of such surfaces are windows in buildings and cars, calm water, signs and vehicle surfaces. During daylight it might well be possible to use mirrorlike reflection by the naked eye or a CCD camera for non-line of sight imaging. However the advantage with active imaging is that one controls the illumination. This will not only allow for low light and night utilization but also for use in cases where the sun or other interfering lights limit the non-line of sight imaging possibility. The range resolution obtained by time gating will reduce disturbing direct reflections and allow simultaneous view in several directions using range discrimination. Measurements and theoretical considerations in this report support the idea of using laser to "see around the corner". Examples of images and reflectivity measurements will be presented together with examples of potential system applications.

    2001-01-01

    The return of the Long Duration Exposure Facility (LDEF) in 1990 brought a wealth of space exposure data on materials, paints, solar cells, adhesives and other data on the many space environments. The effects of the harsh space environments can provide damaging or even disabling effects on a spacecraft, its sub-systems, materials and instruments. In partnership with industry, academia, and other US and international government agencies, the National Aeronautics & Space Administration's (NASA's) Space Environments & Effects (SEE) Program defines the space environments and provides technology development to accommodate or mitigate these harmful environments on the spacecraft. This program (agency-wide in scope but managed at the Marshall Space Flight Center) provides a very comprehensive and focused approach to understanding the space environment. It does this by defining the best techniques for both flight- and groundbased experimentation, updating models which predict both the environments and the environmental effects on spacecraft and ensuring that this information is properly maintained and inserted into spacecraft design programs. This paper will describe the current SEE Program and discuss several current technology development activities associated with the spacecraft charging phenomenon.

  20. Discriminating neutrino see-saw models

    NASA Astrophysics Data System (ADS)

    Hirsch, M.; King, S. F.

    2001-09-01

    We consider how well current theories can predict neutrino mass and mixing parameters, and construct a statistical discriminator which allows us to compare different models to each other. As an example we consider see-saw models based on family symmetry, and single right-handed neutrino dominance, and compare them to each other and to the case of neutrino anarchy with random entries in the neutrino Yukawa and Majorana mass matrices. The predictions depend crucially on the range of the undetermined coefficients over which we scan, and we speculate on how future theories might lead to more precise predictions for the coefficients and hence for neutrino observables. Our results indicate how accurately neutrino masses and mixing angles need to be measured by future experiments in order to discriminate between current models.

    NASA Technical Reports Server (NTRS)

    2002-01-01

    Developed by NASA's Jet Propulsion Laboratory over the past decade with an excess of $15 million of government research and development investment, quantum well infrared photodetectors (QWIPs) are infrared imaging sensors that can operate in the long wavelength portion of the electromagnetic spectrum, where objects at an ambient temperature emit the most energy. QWIPTECH was formed in July 1998 to offer JPL's QWIPs in a commercial format. The company currently holds an exclusive worldwide license to manufacture and sell the infrared photodetector sensors as part of a focal plane array called a QWIP Chip(TM). The QWIP Chip provides high thermal sensitivity (0.001 C) and possesses a broad dynamic range, permitting precise observations over a wide range of temperatures. Since the technology uses heat rather than light, it can "see" in complete darkness and through conditions such as dust, smoke, and light fog.

    Berkeley Lab scientist Peter Nugent discusses a recently discovered supernova that is closer to Earth — approximately 21 million light-years away — than any other of its kind in a generation. Astronomers believe they caught the supernova within hours of its explosion, a rare feat made possible with a specialized survey telescope and state-of-the-art computational tools. The finding of such a supernova so early and so close has energized the astronomical community as they are scrambling to observe it with as many telescopes as possible, including the Hubble Space Telescope.

    2005-01-01

    Retinal input that is suppressed from visual awareness can nevertheless produce measurable aftereffects, revealing neural processes that do not directly result in a conscious percept. We here report that the face identity-specific aftereffect requires a visible face; it is effectively cancelled by binocular suppression or by inattentional blindness of the inducing face. Conversely, the same suppression does not interfere with the orientation-specific aftereffect. Thus, the competition between incompatible or interfering visual inputs to reach awareness is resolved before those aspects of information that are exploited in face identification are processed. We also found that the face aftereffect remained intact when the visual distracters in the inattention experiment were replaced with auditory distracters. Thus, cross-modal or cognitive interference that does not affect the visibility of the face does not interfere with the face aftereffect. We conclude that adaptation to face identity depends on seeing the face. PMID:15629711

    PubMed Central

    Kacsoh, Balint Z.; Lynch, Zachary R.; Mortimer, Nathan T.; Schlenke, Todd A.

    2013-01-01

    Hosts have numerous defenses against parasites, of which behavioral immune responses are an important but under-appreciated component. Here we describe a behavioral immune response Drosophila melanogaster utilizes against endoparasitoid wasps. We found that when flies see wasps they switch to laying eggs in alcohol-laden food sources that protect hatched larvae from infection. This oviposition behavior change, mediated by neuropeptide F, is retained long after wasps are removed. Flies respond to diverse female larval endoparasitoids but not to pupal endoparasitoids or males, showing they maintain specific wasp search images. Furthermore, the response evolved multiple times across the genus Drosophila. Our data reveal a behavioral immune response based on anticipatory medication of offspring, and outline a non-associative memory paradigm based on innate parasite recognition by the host.

  7. Moonlet Propellor: What are we seeing?

    NASA Astrophysics Data System (ADS)

    Lewis, Mark C.; Stewart, G. R.

    2008-09-01

    The presence of a band of moonlets in the A ring has now been established by the identification of bright regions in the rings (Sremcevic, et al., Nature 449, 1019-1021, Tiscareno et al., Astron. J. 135, 1083-1091, 2008). These bright regions are often called propellers based on the characteristic shape seen in simulations. The propeller structures in these simulations are actually low density regions that are edges with high density wakes. The masses of the moonlets in observations are estimated by characteristic scalings seen in simulations where the radial separation between the features scales as the Hill sphere of the moonlet. More recent simulations that include the added realism of particle self-gravity and size distributions find that these interfere with the formation of the high density wakes. This leads to the question of what exactly we are seeing in Cassini observations of the propellers. This work presents large scale simulations ( 25 million particles) aimed at determining whether the bright propellers can be caused by moonlets disrupting gravitational aggregates. Scaling rules for such structures and conditions under which they do or don't form are explored. This work has been supported by NASA PG&G.

    This paper reports that initial results indicate the PLS 3000 pipeline inspection system can significantly reduce the time and cost required to locate and repair leaks in low-pressure natural gas distribution system without interrupting the flow of gas. The system uses a sealed miniature color TV probe into live low-pressure piping to see the leak and other piping problems, such as water infiltration, pipe distortions, structural cracks, broken or misaligned service connections and the presence of foreign matter. The camera is housed in a sealed stainless steel probe that is 1.96-in in diameter and 5.7-in. long. It can travel up to 6000 linear ft in 3- 4- and 6-in piping from a single 3-ft by 5-ft excavation. The probe enters the pipe through a patented Easy Dual Access fitting. The fitting allows the technician to cut into the pipe, remove the coupon and insert the camera probe under sealed conditions. At the conclusion of the examination, the technician seals the access hole with a gasketed steel band clamp.

  9. Multifield of view see-spot optics

    NASA Astrophysics Data System (ADS)

    Lilley, Scott; Vizgaitis, Jay; Everett, Jonathan; Spinazzola, Robert

    2013-06-01

    The increasing availability of sensors that can image in the 1 to 5 μm region has allowed for systems to be developed that utilize the full spectrum. Current mid-wave infrared (MWIR) systems have typically only imaged in the 3 to 5 μm region, but the new detectors allow imaging in the short-wave infrared (SWIR) and MWIR bands on the same image plane. Night Vision and Electronic Sensors Directorate (NVESD) had a requirement to design and build a multiple field of view (FOV) optical system that could image the 1 to 5 μm spectral band utilizing a single, cooled infrared detector. The primary challenge of designing this particular optical system was to get the 1 to 2 (SWIR) μm band to focus at the same image plane as the 3 to 5 (MWIR) μm band in all FOVs. A three-FOV broadband optical system that can image the 1 to 5 μm band on the same image plane was designed and built. Several optical concepts were looked at, and it was decided that a combination of a reflective afocal and refractive imager was the best way to meet the system requirements. The use of a catadioptric system with a single focal plane that images in the 1 to 5 μm spectrum reduces the size of the system and provides the user with see-spot capability.

Each is at risk from invisible storms in near-Earth space. The astrophysical plasmas near our planet store and deliver vast amounts of energy from the Sun in the form of high energy particles, electric currents, and heating of the upper atmosphere. This natural plasma environment is the only one routinely measured in situ over the last 40 years and until recently one of the few we haven't been able to see. Much like atmospheric weather satellites brought global context to that field many decades ago, the IMAGE Mission is now revealing a global context for space weather. The contributions being made by the IMAGE Mission to understanding space weather will be presented along with a brief overview of this dynamic environment. Special emphasis will be placed on research involving the plasmasphere, a toroidal region of relatively dense, cold plasma surrounding the Earth that plays a key role in energy and mass transport through near-Earth space.

  11. Use of Proton SEE Data as a Proxy for Bounding Heavy-Ion SEE Susceptibility

    Although heavy-ion single-event effects (SEE) pose serious threats to semiconductor devices in space, many missions face difficulties testing such devices at heavy-ion accelerators. Low-cost missions often find such testing too costly. Even well funded missions face issues testing commercial off the shelf (COTS) due to packaging and integration. Some missions wish to fly COTS systems with little insight into their components. Heavy-ion testing such parts and systems requires access to expensive and hard-to-access ultra-high energy ion accelerators, or significant system modification. To avoid these problems, some have proposed using recoil ions from high-energy protons as a proxy to bound heavy-ion SEE rates.

  17. See your brands through your customers' eyes.

    Subaru markets an L.L. Bean Outback station wagon. Dell stamps Microsoft and Intel logos on its computers. Such inter-weaving of different companies' brands is now commonplace. But one of the central tools of brand management-portfolio mapping--has not kept pace with changes in the marketplace. Most conventional brand maps include only those brands owned by a company, arranged along organizational lines with little regard for how the brands influence customer perceptions. In this article, the authors present a new mapping tool--the brand portfolio molecule--that reveals the way brands appear to customers. The brand portfolio molecule includes all the brands that factor into a consumer's decision to buy, whether or not the company owns them. The first step in creating a brand portfolio molecule is to determine which brands should or should not be included. The second step is to classify each brand by asking five key questions: 1) How important is this brand to customers' purchase decisions about the brand you're mapping? 2) Is its influence positive or negative? 3) What market position does this brand occupy relative to the other brands in the portfolio? 4) How does this brand connect to the other brands in the portfolio? 5) How much control do you have over this brand? The last step is to map the molecule using a 3-D modeling program or by hand with pen and paper. Individual brands take the form of atoms, and they're clustered in ways that reflect how customers see them. The usefulness of the tool lies in its ability to show the many forces that influence a customer's buying decision--and to provide a powerful new way to think about brand strategy. PMID:11408973

    Twelve-month-olds realize that when an agent cannot see an object, her incomplete perceptions still guide her goal-directed actions. What would happen if the agent had incomplete perceptions because she could see only one part of the object, for example one side of a screen? In the present research, 16-month-olds were first shown an agent who always pointed to a red object, as opposed to a black or a yellow object, suggesting that she preferred red over the other colours. Next, two screens were introduced while the agent was absent. The screens were (1) red or green on both sides; (2) red on the front (infants' side) but green on the back (the agent's side) or vice versa; or (3) only coloured red or green on the front. During test, the agent, who could see only the back of the screens, pointed to one of the two screens. The results revealed that while infants expected the agent to continue acting on her colour preference and point to the red rather than the green screen during test, they did so in accord with the agent's perception of the screens, rather than their own perceptions: they expected the agent to point to the red screen in (1), but to the green-front screen in (2), and they had no prediction of which screen the agent should point to in (3). The implications of the present findings for early psychological reasoning research are discussed. PMID:20121869

  19. HUBBLE SEES SUPERSONIC EXHAUST FROM NEBULA

    NASA Technical Reports Server (NTRS)

    2002-01-01

    2-9 is a striking example of a 'butterfly' or a bipolar planetary nebula. Another more revealing name might be the 'Twin Jet Nebula.' If the nebula is sliced across the star, each side of it appears much like a pair of exhausts from jet engines. Indeed, because of the nebula's shape and the measured velocity of the gas, in excess of 200 miles per second, astronomers believe that the description as a super-super-sonic jet exhaust is quite apt. Ground-based studies have shown that the nebula's size increases with time, suggesting that the stellar outburst that formed the lobes occurred just 1,200 years ago. The central star in M2-9 is known to be one of a very close pair which orbit one another at perilously close distances. It is even possible that one star is being engulfed by the other. Astronomers suspect the gravity of one star pulls weakly bound gas from the surface of the other and flings it into a thin, dense disk which surrounds both stars and extends well into space. The disk can actually be seen in shorter exposure images obtained with the Hubble telescope. It measures approximately 10 times the diameter of Pluto's orbit. Models of the type that are used to design jet engines ('hydrodynamics') show that such a disk can successfully account for the jet-exhaust-like appearance of M2-9. The high-speed wind from one of the stars rams into the surrounding disk, which serves as a nozzle. The wind is deflected in a perpendicular direction and forms the pair of jets that we see in the nebula's image. This is much the same process that takes place in a jet engine: The burning and expanding gases are deflected by the engine walls through a nozzle to form long, collimated jets of hot air at high speeds. M2-9 is 2,100 light-years away in the constellation Ophiucus. The observation was taken Aug. 2, 1997 by the Hubble telescope's Wide Field and Planetary Camera 2. In this image, neutral oxygen is shown in red, once-ionized nitrogen in green, and twice-ionized oxygen in

The first material to be ejected from the explosion travelled at an incredible 100 million km per hour, which is about a tenth of the speed of light or around 100 000 times faster than a passenger jet. Even at this breakneck speed it has taken 10 years to reach a previously existing ring of gas and dust puffed out from the dying star. The images also demonstrate that another wave of material is travelling ten times more slowly and is being heated by radioactive elements created in the explosion. "We have established the velocity distribution of the inner ejecta of Supernova 1987A," says lead author Karina Kjær. "Just how a supernova explodes is not very well understood, but the way the star exploded is imprinted on this inner material. We can see that this material was not ejected symmetrically in all directions, but rather seems to have had a preferred direction. Besides, this direction is different to what was expected from the position of the ring." Such asymmetric behaviour was predicted by some of the most recent computer models of supernovae, which found that large-scale instabilities take place during the explosion. The new observations are thus the first direct confirmation of such models. SINFONI is the leading instrument of its kind, and only the level of detail it affords allowed the team to draw their conclusions. Advanced adaptive optics systems counteracted the blurring effects of the Earth's atmosphere while a technique called integral field spectroscopy allowed the astronomers to study several parts of the supernova's chaotic core simultaneously, leading to the build-up of the 3D image. "Integral field spectroscopy is a special technique where for each pixel we get information about the nature and velocity of the gas," says Kjær. "This means that besides the normal picture we also have the velocity along the line of sight. Because we

  2. NASA's Chandra Sees Brightest Supernova Ever

    NASA Astrophysics Data System (ADS)

    2007-05-01

    WASHINGTON - The brightest stellar explosion ever recorded may be a long-sought new type of supernova, according to observations by NASA's Chandra X-ray Observatory and ground-based optical telescopes. This discovery indicates that violent explosions of extremely massive stars were relatively common in the early universe, and that a similar explosion may be ready to go off in our own galaxy. "This was a truly monstrous explosion, a hundred times more energetic than a typical supernova," said Nathan Smith of the University of California at Berkeley, who led a team of astronomers from California and the University of Texas in Austin. "That means the star that exploded might have been as massive as a star can get, about 150 times that of our sun. We've never seen that before." Chandra X-ray Image of SN 2006gy Chandra X-ray Image of SN 2006gy Astronomers think many of the first generation of stars were this massive, and this new supernova may thus provide a rare glimpse of how the first stars died. It is unprecedented, however, to find such a massive star and witness its death. The discovery of the supernova, known as SN 2006gy, provides evidence that the death of such massive stars is fundamentally different from theoretical predictions. "Of all exploding stars ever observed, this was the king," said Alex Filippenko, leader of the ground-based observations at the Lick Observatory at Mt. Hamilton, Calif., and the Keck Observatory in Mauna Kea, Hawaii. "We were astonished to see how bright it got, and how long it lasted." The Chandra observation allowed the team to rule out the most likely alternative explanation for the supernova: that a white dwarf star with a mass only slightly higher than the sun exploded into a dense, hydrogen-rich environment. In that event, SN 2006gy should have been 1,000 times brighter in X-rays than what Chandra detected.

    2010-06-01

    When listening to speech, we often benefit when also seeing the speaker's face. If this advantage is not domain specific for speech, the recognition of sung lyrics should also benefit from seeing the singer's face. By independently varying the sight and sound of the lyrics, we found a substantial comprehension benefit of seeing a singer. This benefit was robust across participants, lyrics, and repetition of the test materials. This benefit was much larger than the benefit for sung lyrics obtained in previous research, which had not provided the visual information normally present in singing. Given that the comprehension of sung lyrics benefits from seeing the singer, just like speech comprehension benefits from seeing the speaker, both speech and music perception appear to be multisensory processes.

  5. ATST seeing monitor: February 2002 observations at Fuxian Lake

    NASA Astrophysics Data System (ADS)

    Beckers, Jacques M.; Liu, Zhong; Jin, Zhenyu

    2003-02-01

    We describe a solar seeing monitor used for the site testing for the 4 meter US Advanced Technology Solar Telescope and the 1 meter Yunnan Observatory Solar Telescope. It has two parts: a solar Differential Image Motion Monitor (S-DIMM) and a linear array of 6 solar scintillometers (SHABAR= SHAdow BAnd Ranger). The results obtained by both methods are compared on the basis of observations obtained in February 2002 at the Yunnan Observatory Fuxian Lake solar station. Analysis showed that these two ways of measuring the Fried parameter give consistent results. We confirm earlier observations that showed that the boundary layer seeing over lakes is strongly suppressed. The amount of this boundary layer seeing depends on the temperature difference between lake and air and on the wind velocity. We have also carried out seeing observation along a 9.15 km horizontal path across the lake. The Cn2 values derived from these is consistent with the solar observations. They confirm the dependence of Cn2 on the lake-to-air temperature difference. From the SHABAR we find a typical scale height for the boundary layer seeing of 20 meters and from inter-comparison of the S-DIMM and SHABAR observations we derive an outer scale of turbulence of about 50 meters.

  6. The Local Seeing Environment at Big Bear Solar Observatory

    NASA Astrophysics Data System (ADS)

    Verdoni, Angelo; Denker, Carsten

    2007-07-01

    The site survey for the Advanced Technology Solar Telescope (ATST) of the National Solar Observatory was initiated in 2002 to find the best location for a 4 m aperture solar telescope. At the end of a 4 year survey, three sites (Big Bear Solar Observatory [BBSO] in California, Mees Solar Observatory [MSO] on Haleakala, Maui, Hawaii, and Observatorio Roque de los Muchachos, on La Palma, Spain) were identified as excellent sites for high-resolution solar observations. MSO was ultimately chosen as the future ATST site. We present a subset of the ATST site survey data, focusing on the local seeing environment at BBSO. In particular, we are interested in the seeing characteristics at a mountain lake-site observatory, its relation to the local environment and climate, and its implications for the 1.6 m New Solar Telescope (NST) currently being built at BBSO. We find a close correlation of very good seeing conditions with the prevailing wind direction and speed. The observatory building, located at the end of a 300 m causeway, is surrounded by the cool waters of Big Bear Lake, which effectively suppress the ground-layer seeing. Very good seeing conditions from sunrise to sunset are a unique feature of BBSO, which makes it ideally suited for synoptic observations and sustained high-resolution studies of solar activity and space weather.

  7. Integrating seeing measurements into the operations of solar telescopes

    NASA Astrophysics Data System (ADS)

    Denker, C.; Verdoni, A. P.

    2006-06-01

    The New Solar Telescope (NST) is an innovative 1.6-meter, off-axis, open telescope currently being developed and built at the Big Bear Solar Observatory (BBSO). The observatory is situated on a small peninsula in Big Bear Lake, a mountain lake at an altitude of about 2100 m in the San Bernardino Mountains of Southern California. The lake effectively suppresses the boundary layer seeing. Thus, providing consistently very good daytime seeing conditions. BBSO has been identified by the site survey for the Advanced Technology Solar Telescope (ATST) as one of the best sites for solar observations. It is uniquely qualified for long-duration observations requiring high-spatial resolution. This type of observations is typically encountered in solar activity monitoring and space weather forecast. The ATST site survey has collected more than two years of data linking seeing conditions to geographical parameters and local climate. We have integrated these data in a MySQL database and we will use this information in connection with a real-time seeing monitor and weather station to predict the seeing conditions at Big Bear such that scheduling and prioritization of observing programs (e.g., synoptic vs. high-resolution modes) becomes possible.

  8. Exceptional astronomical seeing conditions above Dome C in Antarctica.

    One of the most important considerations when planning the next generation of ground-based optical astronomical telescopes is to choose a site that has excellent 'seeing'--the jitter in the apparent position of a star that is caused by light bending as it passes through regions of differing refractive index in the Earth's atmosphere. The best mid-latitude sites have a median seeing ranging from 0.5 to 1.0 arcsec (refs 1-5). Sites on the Antarctic plateau have unique atmospheric properties that make them worth investigating as potential observatory locations. Previous testing at the US Amundsen-Scott South Pole Station has, however, demonstrated poor seeing, averaging 1.8 arcsec (refs 6, 7). Here we report observations of the wintertime seeing from Dome C (ref. 8), a high point on the Antarctic plateau at a latitude of 75 degrees S. The results are remarkable: the median seeing is 0.27 arcsec, and below 0.15 arcsec 25 per cent of the time. A telescope placed at Dome C would compete with one that is 2 to 3 times larger at the best mid-latitude observatories, and an interferometer based at this site could work on projects that would otherwise require a space mission.

  9. Wishful seeing: more desired objects are seen as closer.

    Although people assume that they see the surrounding environment as it truly is, we suggest that perception of the natural environment is dependent upon the internal goal states of perceivers. Five experiments demonstrated that perceivers tend to see desirable objects (i.e., those that can fulfill immediate goals-a water bottle to assuage their thirst, money they can win, a personality test providing favorable feedback) as physically closer to them than less desirable objects. Biased distance perception was revealed through verbal reports and through actions toward the object (e.g., underthrowing a beanbag at a desirable object). We suggest that seeing desirable objects as closer than less desirable objects serves the self-regulatory function of energizing the perceiver to approach objects that fulfill needs and goals.

  10. Solar Seeing Measurements at the Fuxian Lake Observatory

    2002-05-01

    A collaborative effort between the Yunnan Observatory (YO) of the Chinese Academy of Science and the National Solar Observatory (NSO) has led to the development of the seeing monitor now being used by the NSO for the site testing for the 4 meter Advanced Technology Solar Telescope (ATST). The ATST seeing monitor contains a solar differential image motion monitor (S-DIMM) modeled after the one used by the YO for the site testing at Fuxian Lake. The S-DIMM results in a determination of the Fried Parameter r0. NSO added a linear array of 6 scintillometers which measure cloud cover, the scintillation index and the spatial co-variance of the solar shadow bands. This array is called the SHABAR = SHAdow BAnd Ranger because of its ability to give the height structure of the atmospheric seeing (see the attached web page). In February this year we combined the ATST SHABAR with the S-DIMM at the Fuxian Lake site. We describe the results of 5 days of observations in the February 9 to 14 period. In summary they are: (a) the average seeing was 1.6 arcsec in the solar direction, 1.2 arcsec for zenith direction, (b) for half of the time the boundary layer seeing contribution was negligible (<10%), (c) at the times when it was significant the scale height of the refractive index structure constant Cn2 was determined to be 20 meters, (d) at those times the r0 derived from the SHABAR agreed well with that observed with the S-DIMM, and (e) the r0 derived from the SHABAR at times when it is small exceeds that of the S-DIMM. This is almost certainly due to the outer scale of turbulence being around 10 - 30 meters in the free atmosphere at heights 1 km and above.

    "What would you see if you were riding a beam of light?" This thought experiment, which Einstein reports to have "conducted" at the age of 16, of course has no sensible answer: as Einstein published a decade later, you could never reach the speed of light.2 But it does make sense to ask what you would see if you were traveling close to the speed of light, and one of the first physicists to embark on this effort was George Gamow in his Mr. Tompkins in Wonderland.3 His protagonist is speeding on a bicycle through a city where the speed of light is lower, thus ingeniously taking advantage of the fact that special relativity scales with v/c: for it to kick in, you either have to move very fast (in rather unfamiliar territory), or light has to be slow (in which case special relativity kicks in at everyday velocities in everyday situations). Gamow provides drawings of what Mr. Tompkins and people at the curb would see in this slow-light city, at least, what they would see if one only took into account two of the effects: length contraction and time dilation.4

  19. Long-Term Seeing Characteristics at Big Bear Solar Observatory

    NASA Astrophysics Data System (ADS)

    Denker, C.; Espinosa, O. D.; Nenow, J.; Marquette, W. H.

    2003-05-01

    We present observations of long-term seeing characteristics from June 1997 to September 2002 obtained with Seykora-type scintillometers at Big Bear Solar Observatory (BBSO). BBSO is an ideal site for ground-based campaign-style observations. Since BBSO is situated on a small island in a 2,000 m high mountain lake in the cloudless mountains of Souther California, it benefits from excellent seeing conditions all day long. The atmospheric turbulence that degrades images originates primarily from two layers near the ground and at the level of the jet stream. BBSO's dome is located at the end of a 300 m long causeway jutting into the lake. Since the lake, with its cool waters, provides a natural inversion, and the dome has three kilometers of open water to its west, the boundary layer seeing is effectively suppressed. In addition, the east-west orientation of the Big Bear Valley provides a natural channel for the prevailing winds from the west resulting in a nearly laminar flow at the observatory site. We present a comparison of scintillometer data with climate data and analyze a one year long sub-set for local seeing variations near the lake shore and at the observatory island. We would like to thank Jacques Beckers and the National Solar Observatory for providing the scintillometer data. This work was supported by NSF under grant ATM 00-86999, ATM 00-76602, and ATM 02-36945 and by NASA under grant NAG 5-9682.

  14. Seeing and being seen: Shame in the clinical situation.

    PubMed

    Steiner, John

    2015-12-01

    Shame may prevent the patient from emerging from a psychic retreat. As begins to do so he confronts two fears, first of seeing the object more clearly and second of being seen become prominent. Seeing leads to deeper and more distressing feelings connected with guilt and depression as the damage done to good objects is recognized. However it cannot be faced if shame leads to a demand for immediate relief. Shame is a prominent feature of the analytic situation and recognizing this may help the analyst to support his patients to tolerate the discomfort of being seen so that the conflicts about seeing can be worked through. Two clinical examples are briefly discussed. In the first feelings of inferiority lessened as they were analysed and allowed appreciative and depressive feelings to emerge. In the second embarrassment was associated with progress that the patient felt he had made but was embarrassed to admit. It is argued that the analysis of shame in the analytic situation is necessary so that being seen can be tolerated and allow the conflicts over seeing to be worked through. PMID:26481856

    High power HF radio waves exciting the ionosphere provide aeronomers with a unique space-based laboratory capability. The High-Frequency Active Auroral Research Program (HAARP) in Gakona, Alaksa is the world's largest heating facility, providing effective radiated powers in the gigawatt range. Experiments performed at HAARP have allowed researchers to study many non-linear effects of wave-plasma interactions. Stimulated Electromagnetic Emission (SEE) is of interest to the ionospheric community for its diagnostic purposes. Typical SEE experiments at HAARP have focused on characterizing the parametric decay of the electromagnetic pump wave into several different wave modes such as upper and lower hybrid, ion acoustic, ion-Bernstein and electron-Bernstein. These production modes have been extensively studied at HAARP using traditional beam heating patterns and SEE detection. New results are present from HAARP experiments using a "twisted beam" excitation mode. Unlike traditional heating beams used at HAARP or other heating facilities, the twisted beam attempts to impart orbital angular momentum (OAM) into the heating region. Analysis of twisted beam heating shows that the SEE results obtained are nearly identical to the modes without OAM. One difference in the twisted beam mode is the heating region produced is in the shape of a ring as opposed to the more traditional "solid spot" region. The ring heating pattern may be more conducive to the creation of artificial airglow layers. The results of these runs include artificial layer creation and evolution as pertaining to the twisted beam pattern. The SEE measurements aid the interpretation of the twisted beam interactions in the ionosphere.

  16. iSeeChange: Crowdsourced Climate Change Reporting

    NASA Astrophysics Data System (ADS)

    Drapkin, J. K.

    2012-12-01

    Directly engaging local communities about their climate change experiences has never been more important. As weather and climate become more unpredictable, these experiences provide a baseline for community decisions, developing adaptation strategies, and planning for the future. Typically, climate change is documented in a top-down fashion: a scientist has a question, makes observations, and publishes a study; in the best case scenario, a journalist reports on the results; if there's time, a local anecdote is sought to put the results in a familiar context. iSeeChange, a public media project funded by the Corporation for Public Broadcasting, reports local environmental change in reverse and turns community questions and conversations with scientists into reported stories that promote opportunities to learn about climate change's affects on the environment and daily life. iSeeChange engages residents of the North Fork Valley region of western Colorado in a multiplatform conversation with scientists about how they perceive their environment is changing through the course of a year - season to season. By bringing together public radio, a mobile reporting and cellular engagement strategy, and a custom crowdsourcing multimedia platform, iSeeChange provides a central access point to collect observations (texts, photographs, voice recordings, and video), organize conversations and interviews with scientists, and report stories online and on air. In this way, iSeeChange is building a dynamic crowdsourced reservoir of information that can increase awareness of environmental problems and potentially disseminate useful information about climate change and successful adaptation strategies. Ultimately, by understanding the community's information needs in a localized question-driven context, the iSeeChange platform presents opportunities for the science community to better understand the value of information and develop better ways to tailor information for communities to use

    2009-01-01

    People see with feeling. We ‘gaze’, ‘behold’, ‘stare’, ‘gape’ and ‘glare’. In this paper, we develop the hypothesis that the brain's ability to see in the present incorporates a representation of the affective impact of those visual sensations in the past. This representation makes up part of the brain's prediction of what the visual sensations stand for in the present, including how to act on them in the near future. The affective prediction hypothesis implies that responses signalling an object's salience, relevance or value do not occur as a separate step after the object is identified. Instead, affective responses support vision from the very moment that visual stimulation begins. PMID:19528014

    The Supernova Cosmology Project (SCP) is executing "See Change", a large HST program to look for possible variation in dark energy using supernovae at z>1. As part of the survey, we often must make time-critical follow-up decisions based on multicolor detection at a single epoch. We demonstrate the use of the SNCosmo software package to obtain simulated fluxes in the HST filters for type Ia and core-collapse supernovae at various redshifts. These simulations allow us to compare photometric data from HST with the distribution of the simulated SNe through methods such as Random Forest, a learning method for classification, and Gaussian Kernel Estimation. The results help us make informed decisions about triggered follow up using HST and ground based observatories to provide time-critical information needed about transients. Examples of this technique applied in the context of See Change are shown.

    Preoperative marking is an integral part of the care of patients undergoing surgical procedures. It occurs on a daily basis in hospitals and involves all members of the healthcare staff and the patient. Incorrect marking or errors can lead to devastating consequences for the patient and staff involved. We present an unusual case of seeing double arrows on a patient undergoing emergency orthopaedic surgery, despite standard preoperative marking procedures. This was recognised in the anaesthetic room and the correct site was confirmed. We aim to highlight this specific problem and remind all involved in preoperative marking of the dangers of a mirror imprint, thereby avoiding seeing double in the anaesthetic or operating room.

    Major solar eruptive events consisting of both a large flare and a near simultaneous large fast coronal mass ejection (CME), are the most powerful explosions and also the most powerful and energetic particle accelerators in the solar system, producing solar energetic particles (SEPs) up to tens of GeV for ions and 10s-100s of MeV for electrons. The intense fluxes of escaping SEPs are a major hazard for humans in space and for spacecraft. Furthermore, the solar plasma ejected at high speed in the fast CME completely restructures the interplanetary medium, producing the most extreme space weather in geospace, at other planets, and in the heliosphere. Thus, the understanding of the flare/CME energy release process and of the related particle acceleration processes in SEEs is a major goal in Heliophysics. Here we present a concept for a Solar Eruptive Events (SEE) mission, consisting of a comprehensive set of advanced new instruments on the single spacecraft in low Earth orbit, that focus directly on the coronal energy release and particle acceleration in flares and CMEs. SEE will provide new focussing hard X-ray imaging spectroscopy of energetic electrons in the flare acceleration region, new energetic neutral atom (ENA) imaging spectroscopy of SEPs being accelerated by the CME at altitudes above 2 solar radii, gamma-ray imaging spectroscopy of flare-accelerated energetic ions, plus detailed EUV/UV/Soft X-ray diagnostics of the plasmas density, temperature, and mass motions in the energy release and particle acceleration regions. Together with ground-based measurements of coronal magnetic fields from ATST, FASR, and COSMO, SEE will enable major breakthroughs in our understanding of the fundamental physical processes involved in major solar eruptive events.

    Fearful body language is a salient signal alerting the observer to the presence of a potential threat in the surrounding environment. Although detecting potential threats may trigger an immediate reduction of motor output in animals (i.e., freezing behavior), it is unclear at what point in time similar reductions occur in the human motor cortex and whether they originate from excitatory or inhibitory processes. Using single-pulse and paired-pulse transcranial magnetic stimulation (TMS), here we tested the hypothesis that the observer's motor cortex implements extremely fast suppression of motor readiness when seeing emotional bodies - and fearful body expressions in particular. Participants observed pictures of body postures and categorized them as happy, fearful or neutral while receiving TMS over the right or left motor cortex at 100-125 msec after picture onset. In three different sessions, we assessed corticospinal excitability, short intracortical inhibition (SICI) and intracortical facilitation (ICF). Independently of the stimulated hemisphere and the time of the stimulation, watching fearful bodies suppressed ICF relative to happy and neutral body expressions. Moreover, happy expressions reduced ICF relative to neutral actions. No changes in corticospinal excitability or SICI were found during the task. These findings show extremely rapid bilateral modulation of the motor cortices when seeing emotional bodies, with stronger suppression of motor readiness when seeing fearful bodies. Our results provide neurophysiological support for the evolutionary notions that emotion perception is inherently linked to action systems and that fear-related cues induce an urgent mobilization of motor reactions.

    Through two temporal modalities, the time of the holographic image (the performance recorded time) and the performance time of the public, we create "a new space for the image", whose structure is influenced by the holographic images and the public as performer. In the tension between the action space of the participants and the virtual space of holographic images, it exists the time image that goes beyond the issue of the movement and has a direct relationship with the participant's thought. In this series of digital holographic images and lenticulars, we are using an old camera Canon IS3 and a new HD Canon, on the HOLOrail, to capture old fashion scenes and other scenes having a "nowadays" look and put them on the surface of the holographic plate.

    For inversion-symmetric topological insulators and superconductors characterized by [Formula: see text] topological invariants, two scaling schemes are proposed to judge topological phase transitions driven by an energy parameter. The scaling schemes renormalize either the phase gradient or the second derivative of the Pfaffian of the time-reversal operator, through which the renormalization group flow of the driving energy parameter can be obtained. The Pfaffian near the time-reversal invariant momentum is revealed to display a universal critical behavior for a great variety of models examined. PMID:27400801

    Nonlinear interactions of high power HF radio waves in the ionosphere provide aeronomers with a unique space-based laboratory capability. The High-Frequency Active Auroral Research Program (HAARP) in Gakona, Alaska is the world's largest heating facility, yielding effective radiated powers in the gigawatt range. New results are present from HAARP experiments using a "twisted beam" excitation mode. Analysis of twisted beam heating shows that the SEE results obtained are identical to more traditional patterns. One difference in the twisted beam mode is the heating region produced is in the shape of a ring as opposed to the more traditional "solid spot" region from a pencil beam. The ring heating pattern may be more conducive to the creation of stable artificial airglow layers because of the horizontal structure of the ring. The results of these runs include artificial layer creation and evolution as pertaining to the twisted beam pattern. The SEE measurements aid the interpretation of the twisted beam interactions in the ionosphere.

    The increasing availability of sensors that can image in the 1-5 micron region has allowed for systems to be developed that utilize the full spectrum. Past MWIR systems have typically only imaged in the 3-5 micron region, but the new detectors allow imaging in the SWIR and MWIR bands with the same system. The use of a single FPA reduces SWAP and allows the user to see laser rangefinder and laser designator wavelengths. NVESD and Axsys have designed and built a SWIR/MWIR optical system that images in the 1-5 micron band. The optical system utilizes a cooled infrared detector that images in the 3-5 micron band as well as 1.04 - 1.08 and 1.54 microns without having to refocus the system to see the SWIR wavelengths. This provided an optical challenge to design a system that would image from 1-5 microns on the same detector. A combination reflective/refractive design was chosen in order to minimize packaging and meet the different FOV requirements. This paper discusses the design and development of a multi-FOV optical system with the capability to image across the 1-5 micron spectral band utilizing a combination of reflective and refractive components.

    Situational awareness is a critical issue for the modern battle and security systems improvement of which will increase human performance efficiency. There are multiple research project and development efforts based on omni-directional (fish-eye) electro-optical and other frequency sensor fusion systems implementing head-mounted visualization systems. However, the efficiency of these systems is limited by the human eye-brain system perception limitations. Humans are capable to naturally perceive the situations in front of them, but interpretation of omni-directional visual scenes increases the user's mental workload, increasing human fatigue and disorientation requiring more effort for object recognition. It is especially important to reduce this workload making rear scenes perception intuitive in battlefield situations where a combatant can be attacked from both directions. This paper describes an experimental model of the system fusion architecture of the Visual Acoustic Seeing (VAS) for representation spatial geometric 3D model in form of 3D volumetric sound. Current research in the area of auralization points to the possibility of identifying sound direction. However, for complete spatial perception it is necessary to identify the direction and the distance to an object by an expression of volumetric sound, we initially assume that the distance can be encoded by the sound frequency. The chain: object features -> sensor -> 3D geometric model-> auralization constitutes Volumetric Acoustic Seeing (VAS). Paper describes VAS experimental research for representing and perceiving spatial information by means of human hearing cues in more details.

    The ESO OWL site survey plan includes the analysis of the astronomical quality of the Atlas mountains in Morocco. In this paper we are presenting the first long time measurement of optical turbulence at Oukaimeden site. For this work we built an instrument called ADIMM for an Automated Differencial Image Motion Monitor, and we use it to the measure the optical turbulence at the Oukaimeden Site. We are describing the instrument and reporting the first results obtained after six month of working on this project. The results of night-time seeing measurements carried out during the period from Jun 14 up to October 01 2003 are presented. The median and mean values of the seeing for the entire period of observations are respectively 0.75" and 0.84". This work was organized in the framework of contract Num.69651/ODG/02/9005/GWI between the European Southern Observatory (ESO) and Astrophysics and Physics of High Energy Laboratory of the Faculty of Sciences, Cadi Ayyad University (LPHEA).

    Dome and mirror seeing are critical effects influencing the optical performance of ground-based telescopes. Computational Fluid Dynamics (CFD) can be used to obtain the refractive index field along a given optical path and calculate the corresponding image quality utilizing optical modeling tools. This procedure is validated using measurements from the Keck II and CFHT telescopes. CFD models of Keck II and CFHT observatories on the Mauna Kea summit have been developed. The detailed models resolve all components that can influence the flow pattern through turbulence generation or heat release. Unsteady simulations generate time records of velocity and temperature fields from which the refractive index field at a given wavelength and turbulence parameters are obtained. At Keck II the Cn2 and l0 (inner scale of turbulence) were monitored along a 63m path sensitive primarily to turbulence around the top ring of the telescope tube. For validation, these parameters were derived from temperature and velocity fluctuations obtained from CFD simulations. At CFHT dome seeing has been inferred from their database that includes telescope delivered Image Quality (IQ). For this case CFD simulations were run for specific orientations of the telescope respect to incoming wind, wind speeds and outside air temperature. For validation, temperature fluctuations along the optical beam from the CFD are turned to refractive index variations and corresponding Optical Path Differences (OPD) then to Point Spread Functions (PSF) that are ultimately compared to the record of IQ.

    The objective of this coarse Single Event Effect (SEE) test is to determine the suitability of the commercial Virtex-II Pro family for use in spaceflight applications. To this end, this test is primarily intended to determine any Singe Event Latchup (SEL) susceptibilities for these devices. Secondly, this test is intended to measure the level of Single Event Upset (SEU) susceptibilities and in a general sense where they occur. The coarse SEE test was performed on a commercial XC2VP7 device, a relatively small single processor version of the Virtex-II Pro. As the XC2VP7 shares the same functional block design and fabrication process with the larger Virtex-II Pro devices, the results of this test should also be applicable to the larger devices. The XC2VP7 device was tested on a commercial Virtex-II Pro development board. The testing was performed at the Cyclotron laboratories at Texas A&M and Michigan State Universities using ions of varying energy levels and fluences.

    The Xilinx Virtex-II Pro is a platform FPGA that embeds multiple microprocessors within the fabric of an SRAM-based reprogrammable FPGA. The variety and quantity of resources provided by this family of devices make them very attractive for spaceflight applications. However, these devices will be susceptible to single event effects (SEE), which must be mitigated. To use the Virtex-II Pro reliably in space applications, these devices must first be tested to determine if they are susceptible to single event latchup (SEL), the degree to which they are susceptible to single event upsets (SEU) and single event transients (SET), and how these effects are manifested in the device. With this information, mitigations schemes can be developed and tested that address the specific susceptiblities of these devices. This initial SEE test uses a commercial off the shelf Virtex-II Pro evaluation board, with a single processor XC2VP7 FPGA. The FPGA on this board is an acid etched device, which can be partially covered with a shield. The shield covers a portion of the logic, routing, and memory resources along with some of the RocketIO transceivers. The processor, along with a large portion of logic, routing, memory, and transceivers are left exposed. This test will be performed at the Cyclotron Laboratories at Texas A&M University and Michigan State University using ions of varying energy levels and fluencies.

    There is growing interest in measuring seeing at existing and prospective telescope sites. Several methods exist to quantify seeing, one among them is by measuring the scintillation of solar or lunar light using a photodiode. A shadow band ranger (SHABAR) analyses the covariance of the signals from an array of such photodiodes, which allows for the spatial resolution of the index of refraction above the SHABAR device. This allows one to estimate the index of refraction structure parameter as a function of height, C2n(h). Although a SHABAR has a limited range compared to a differential image motion monitor (DIMM) or the latest wavefront sensors, the advantage is that it does not need telescope optics to work. A SHABAR device can be made very compact and can operate independent of other instruments. We describe the design of such a SHABAR device with six photodiodes that can operate virtually indefinitely without requiring human intervention. An inversion algorithm is used to convert the raw scintillation signals of the photodiodes to the desired C2n(h) profile and a value for the Fried parameter r0 at height zero. We show that it is possible to perform inversions of 10 s periods in real time on relatively low-end hardware, such as an Intel Atom based computer, which allows the results to be presented live to astronomers, who can use this information to help make decisions about their observation schedule.

    Objectives To ascertain what meaning individuals attach to perceiving images of their own interior body and how the images and their meanings affect the clinical consultation. Design Face-to-face semistructured interviews. Participants 25 adult patients in southern England who, within the preceding 12 months, had been referred for diagnostic imaging. Setting Community. Results For patients, being shown their own X-rays, MRIs or CT images creates a variety of effects: (1) a sense of better understanding of the diagnosis; (2) validation of their sensory and emotional response to the illness or injury and (3) an alteration to the tenor and nature of the clinical encounter between patient and physician. In addition to meanings attached to these images, patients also impute meaning to the physician's decision not to share an image with them. The desire to see their image was greater in those patients with a skeletal injury; patients are less keen on viewing abdominal or other soft tissue images. Conclusions Viewing images of one's interior, invisible body is powerful and resonant in a number of ways. The experience of not seeing, whether through the patient's or the physician's choice, is also fraught with meaning. PMID:25082418

    A fundamental property of most animals is the ability to see whether an object is approaching on a direct collision course and, if so, when it will collide. Using high-density electroencephalography in 5- to 11-month-old infants and a looming stimulus approaching under three different accelerations, we investigated how the young human nervous system extracts and processes information for impending collision. Here, we show that infants’ looming related brain activity is characterised by theta oscillations. Source analyses reveal clear localised activity in the visual cortex. Analysing the temporal dynamics of the source waveform, we provide evidence that the temporal structure of different looming stimuli is sustained during processing in the more mature infant brain, providing infants with increasingly veridical time-to-collision information about looming danger as they grow older and become more mobile.

The SIRTF Science Center has established a series of educational products based around the theme, "Infrared: More Than Your Eyes Can See." Students can discover infrared for themselves, using a classroom activity that replicates William Herschel's original 1800 experiment. We also have a video (free for educators) that uses the latest color infrared cameras to show students the contrast between visible and infrared light. For the web, we have websites that range from the general (a tutorial about infrared light) to the specific (links to infrared applications in geology, medicine, law inforcement, and astronomy). Visit our website or come by our booth to pick up an assortment of educational products, including slide sets, lithographs, posters, brochures, and videos.

  2. Seeing is Believing? Evidence from Property Prices in Inundated Areas.

    We use hedonic property models to estimate the changes in implicit flood risk premium following a large flood event. Previous studies have used flood hazard maps to proxy flood risk. In addition to knowing whether a property lies in the floodplain, we use a unique data set with the flood inundation map. We find that the price discount for properties in the inundated area is substantially larger than in comparable properties in the floodplain that did not get inundated. This suggests that, in addition to capturing an information effect, the larger discount in inundated properties reflects potential uninsurable flood damages, and supports a hypothesis that homeowners respond better to what they have visualized ("seeing is believing").

    Time-domain astrophysics benefits from extreme-latitude sites, which can combine intrinsically extended nighttime with good sky conditions. One such location is the Polar Environment Atmospheric Research Laboratory (PEARL), at 80° North latitude, on the northwestern edge of Ellesmere Island, Canada. Experience gained deploying seeing monitors there has been incorporated into an automated system called “Ukaliq” after the common arctic hare, which is also very well suited to its local environment. Even with modest aperture, high photometric reliability may be achieved using simple adaptive optics together with observing strategies that best fit the unique set of advantages available at PEARL: excellent image quality maintained during many clear, calm, dark periods of 100 hours or more. A potential multi-year search for gravitational microlensing of quasars with Ukaliq helps illustrate this niche in the era of large wide-field survey facilities.

    In this paper, we propose a volume visualization system that accepts direct manipulation through a sketch-based What You See Is What You Get (WYSIWYG) approach. Similar to the operations in painting applications for 2D images, in our system, a full set of tools have been developed to enable direct volume rendering manipulation of color, transparency, contrast, brightness, and other optical properties by brushing a few strokes on top of the rendered volume image. To be able to smartly identify the targeted features of the volume, our system matches the sparse sketching input with the clustered features both in image space and volume space. To achieve interactivity, both special algorithms to accelerate the input identification and feature matching have been developed and implemented in our system. Without resorting to tuning transfer function parameters, our proposed system accepts sparse stroke inputs and provides users with intuitive, flexible and effective interaction during volume data exploration and visualization.

    The Human Exploration Science Office within the ARES Directorate has undertaken a new class of handheld camera photographic observations of the Earth as seen from the International Space Station (ISS). For years, astronauts have attempted to describe their experience in space and how they see the Earth roll by below their spacecraft. Thousands of crew photographs have documented natural features as diverse as the dramatic clay colors of the African coastline, the deep blues of the Earth's oceans, or the swirling Aurora Borealis of Australia in the upper atmosphere. Dramatic recent improvements in handheld digital single-lens reflex (DSLR) camera capabilities are now allowing a new field of crew photography: night time-lapse imagery.

    The power of X-ray crystal structure analysis as a technique is to 'see where the atoms are'. The results are extensively used by a wide variety of research communities. However, this 'seeing where the atoms are' can give a false sense of security unless the precision of the placement of the atoms has been taken into account. Indeed, the presentation of bond distances and angles to a false precision (i.e. to too many decimal places) is commonplace. This article has three themes. Firstly, a basis for a proper representation of protein crystal structure results is detailed and demonstrated with respect to analyses of Protein Data Bank entries. The basis for establishing the precision of placement of each atom in a protein crystal structure is non-trivial. Secondly, a knowledge base harnessing such a descriptor of precision is presented. It is applied here to the case of salt bridges, i.e. ion pairs, in protein structures; this is the most fundamental place to start with such structure-precision representations since salt bridges are one of the tenets of protein structure stability. Ion pairs also play a central role in protein oligomerization, molecular recognition of ligands and substrates, allosteric regulation, domain motion and α-helix capping. A new knowledge base, SBPS (Salt Bridges in Protein Structures), takes these structural precisions into account and is the first of its kind. The third theme of the article is to indicate natural extensions of the need for such a description of precision, such as those involving metalloproteins and the determination of the protonation states of ionizable amino acids. Overall, it is also noted that this work and these examples are also relevant to protein three-dimensional structure molecular graphics software. PMID:25075321

    Radiation Effects Microscopy is an extremely useful technique in failure analysis of electronic parts used in radiation environment. It also provides much needed support for development of radiation hard components used in spacecraft and nuclear weapons. As the IC manufacturing technology progresses, more and more overlayers are used; therefore, the sensitive region of the part is getting farther and farther from the surface. The thickness of these overlayers is so large today that the traditional microbeams, which are used for REM are unable to reach the sensitive regions. As a result, higher ion beam energies have to be used (> GeV), which are available only at cyclotrons. Since it is extremely complicated to focus these GeV ion beams, a new method has to be developed to perform REM at cyclotrons. We developed a new technique, Ion Photon Emission Microscopy, where instead of focusing the ion beam we use secondary photons emitted from a fluorescence layer on top of the devices being tested to determine the position of the ion hit. By recording this position information in coincidence with an SEE signal we will be able to indentify radiation sensitive regions of modern electronic parts, which will increase the efficiency of radiation hard circuits.

  10. Do Patients and Dentists See Ethics the Same Way?

    PubMed

    Chambers, David W

    2015-01-01

    The most common approach to ethics in dentistry and bioethics generally is through principles. To be effective, principles must be interpreted in particular situations, and the skill of interpretation requires many years of practice with feedback. The opinions of 91 dentists and 54 patients regarding multiple potential actions and justifications for these actions were gathered for eight dental ethics cases. The summary responses of dentists and patients have been integrated as feedback in an online ethics education exercise that individual dentists can use (see www.dental ethics.org/idea). The dataset of responses was also analyzed for general findings. It emerged that patients and dentists agree to a substantial extent on the average approaches, but they differ systematically on certain of the details. Some ethical issues stimulated a narrow range of responses while others, especially those of a nonclinical nature were regarded as ambiguous and are thus good candidates for future ethics training. A factor analysis revealed a five-dimension structure underlying dental ethics. Patients are most apt to view dentistry using a lens of oral health outcomes while practitioners prefer to stress the process and the technical dimensions of practice. The largest area of difference was patients' much greater interest in dentists assuming an active role as patient oral health advocates with their colleagues. PMID:26562981

  12. Emergency providers see big potential for Google Glass.

    2014-05-01

    Emergency providers are among the first in health care to experiment with Google Glass, a computer that is worn like a traditional set of glasses, enabling clinicians to pull up critical information from a patient's electronic medical record (EMR) or call for assistance without looking away from the patient. Special applications of the device can also be used to facilitate telemedicine consults with specialists while patients are still in the ED. According to early users, protecting patient privacy has not been a problem in early applications of the device. However, state-level laws remain a barrier to large-scale implementation of the technology in some regions. Emergency providers at Beth Israel Deaconess Medical Center in Boston, MA, see Google Glass as another platform for their ED information system. The approach is being used to facilitate hands-free communications and to expedite workflow. At Rhode Island Hospital in Providence, RI, emergency providers are testing a telemedicine application for Glass that enables providers to connect patients with off-site dermatologists while they are still in the ED, eliminating the need for additional specialty appointments. Early users believe that Glass and similar innovations will eventually play a strong role in preventing readmissions by providing remote care to patients--especially in the first few days following discharge from the hospital or ED.

    This report has addressed the question of how the Maori community sees the system of oral health care by indicating the complex factors influencing the Maori community's attitude toward health issues. These factors preclude the Maori community from many of the perceived benefits of the present oral health-care system. There is a need in this current climate of debate over health policies to re-focus on primary prevention policies that will be relevant to the Maori community of today. No one is seen in the Maori community to be articulating concern for oral health issues. The challenge for the Dental Council of New Zealand is how then to create a focus on oral health issues within the Maori community, and to actively promote oral health care and encourage usage of a system that is affordable, available, accessible, and appropriate. Practical and relevant recommendations arising from Rapuora: Health and Maori Women 1984 and the Hui Hauora Mokopuna, 1990(10) should be considered when planning future health-care systems. Health was one of the four key areas highlighted in the Ka Awatea report, and it will be an important feature of the work of the new Ministry of Maori Development. It is timely that the Dental Council of New Zealand and the Ministry of Maori Development should facilitate oral health-care systems for the future in partnership with the Maori community.

    We examine the requirements for on-board aircraft sensor systems that would allow pilots to 'see through' poor weather, especially fog, and land and rollout aircraft under conditions that currently cause flight cancellations and airport closures. Three visual aspects of landing and rollout are distinguished: guidance, hazard detection and hazard recognition. The visual features which support the tasks are discussed. Three broad categories of sensor technology are examined: passive millimeter wave (PMMW), imaging radar, and passive infrared (IR). PMMW and imaging radar exhibit good weather penetration, but poor spatial and temporal resolution. Imaging radar exhibits good weather penetration, but typically relies on a flat-earth assumption which can lead to interpretive errors. PMMW systems have a narrow field of view. IR has poorer weather penetration but good spatial resolution. We recommend using both millimeter-wave and infrared sensor systems, blending the images using multiresolution digital-image pyramid-processing technology, and fusing the resulting real-time images with stored database imagery of the same scene.

  15. Is Seeing Believing? Perceptions of Wildfire Risk Over Time.

    Champ, Patricia A; Brenkert-Smith, Hannah

    2016-04-01

    Ongoing challenges to understanding how hazard exposure and disaster experiences influence perceived risk lead us to ask: Is seeing believing? We approach risk perception by attending to two components of overall risk perception: perceived probability of an event occurring and perceived consequences if an event occurs. Using a two-period longitudinal data set collected from a survey of homeowners living in a fire-prone area of Colorado, we find that study participants' initial high levels of perceived probability and consequences of a wildfire did not change substantially after extreme wildfire events in the intervening years. More specifically, perceived probability of a wildfire changed very little, whereas the perceived consequences of a wildfire went up a bit. In addition, models of risk perceptions show that the two components of overall risk perception are correlated with somewhat different factors, and experience is not found to be one of the strongest correlates with perceived risk. These results reflect the importance of distinguishing the components of overall risk and modeling them separately to facilitate additional insights into the complexities of risk perceptions, factors related to perceived risk, and change in risk perceptions over time.

  16. Robotic SLODAR Development for Seeing Evaluation at the Bohyun Observatory

    NASA Astrophysics Data System (ADS)

    Lee, J.; Wilson, R.; Butterley, T.; Choi, Y.; Lee, S.

    We had developed a robotic SLODAR (SLOpe Detection And Ranging) for characterization of the vertical profile of atmospheric optical turbulence at the Bohyun observatory, South Korea. The SLODAR had been developed in partnership between Kongju National Univ. South Korea and Durham Univ., U.K. The SLODAR instrument consists of a robotic 50 cm telescope feeding into a pair of Shack Hartmann wavefront sensors. SLODAR analysis of the wavefront sensor data yields turbulence profiles of the surface layer of turbulence, with the vertical resolution depending on the separation and elevation of the target stars.The total seeing ( r0 ) is also measured, and by subtracting the directly measured turbulence from the total the unresolved strength (above the maximum sensing altitude) can also be determined. The instrument has two observing modes, "wide" and "narrow" depending on the angular sepration of pairs of stars. In wide mode regime, narrower targets are chosen ( 2 ~ 4 arcmin) such that the ground layer profile is measured up to ~500m. In narrow mode, very narrow targets (10 ~ 15 arcsec) are measured to provide the turbulence profile with coarse resolution up to ~6km. The automated SLODAR turbulence profiler at the Boyun Observatory is currently under remote and robotic operation since last June. We reports herein the development of the SLODAR with first observation results.

    PICARD is a space mission developed to observe the Sun at high angular resolution. One of the main space objectives of PICARD is to measure the solar diameter with few milli arc-seconds accuracy. A replica of the space instrument will be installed at Calern Observatory in order to test our ability to make such measurement from ground with enough accuracy. High angular resolution observations with ground-based instrument are however limited by atmospheric turbulence. The seeing monitor MISOLFA is developed to give all observation conditions at the same moments when solar images will be recorded with the twin PICARD instruments. They will be used to link ground and space measurements. An overview of the PICARD mission and the solar ground-based experiments will be rst given. Optical properties of MISOLFA will be after presented. The basic principles to measure atmospheric parameters and the methods used to obtain them from solar images will be given. Finally, some recent results obtained at Calern Observatory will be presented and discussed.

    Recent years have shown a gradual shift in the content of biomedical publications that is freely accessible, from titles and abstracts to full text. This has enabled new forms of automatic text analysis and has given rise to some interesting questions: How informative is the abstract compared to the full-text? What important information in the full-text is not present in the abstract? What should a good summary contain that is not already in the abstract? Do authors and peers see an article differently? We answer these questions by comparing the information content of the abstract to that in citances—sentences containing citations to that article. We contrast the important points of an article as judged by its authors versus as seen by peers. Focusing on the area of molecular interactions, we perform manual and automatic analysis, and we find that the set of all citances to a target article not only covers most information (entities, functions, experimental methods, and other biological concepts) found in its abstract, but also contains 20% more concepts. We further present a detailed summary of the differences across information types, and we examine the effects other citations and time have on the content of citances. PMID:23227044

    Hypoxia-inducible factor-1 (HIF-1) is an [Formula: see text] dimeric transcription factor. Because HIF-1[Formula: see text] is instable with oxygen, HIF-1 is scarce in normal mammalian cells. However, HIF-1[Formula: see text] is expressed in pathological conditions such as cancer and obesity. Inhibiting HIF-1[Formula: see text] may be of therapeutic value for these pathologies. Here, we investigated whether emodin, derived from the herb of Rheum palmatum L, which is also known as Chinese rhubarb, and is native to China, regulates HIF-1[Formula: see text] expression. Male C57BL/6 mice without or with diet-induced obesity were treated with emodin for two weeks, while control mice were treated with vehicle. HIF-1[Formula: see text] expression was determined by Western blot. We found that emodin inhibited obesity-induced HIF-1[Formula: see text] expression in liver and skeletal muscle but did not regulate HIF-1[Formula: see text] expression in the kidneys or in intra-abdominal fat. In vitro, emodin inhibited HIF-1[Formula: see text] expression in human HepG2 hepatic cells and Y1 adrenocortical cells. Further, we investigated the mechanisms of HIF-1[Formula: see text] expression in emodin-treated HepG2 cells. First, we found that HIF-1[Formula: see text] had normal stability in the presence of emodin. Thus, emodin did not decrease HIF-1[Formula: see text] by stimulating its degradation. Importantly, emodin decreased the activity of the signaling pathways that led to HIF-1[Formula: see text] biosynthesis. Interestingly, emodin increased HIF-1[Formula: see text] mRNA in HepG2 cells. This may be a result of feedback in response to the emodin-induced decrease in the protein of HIF-1[Formula: see text]. In conclusion, emodin decreases hepatic HIF-1[Formula: see text] by inhibiting its biosynthesis. PMID:27430909

  20. What Can We Learn From Proton Recoils about Heavy-Ion SEE Sensitivity?

    2016-01-01

    The fact that protons cause single-event effects (SEE) in most devices through production of light-ion recoils has led to attempts to bound heavy-ion SEE susceptibility through use of proton data. Although this may be a viable strategy for some devices and technologies, the data must be analyzed carefully and conservatively to avoid over-optimistic estimates of SEE performance. We examine the constraints that proton test data can impose on heavy-ion SEE susceptibility.

    The see-through stock in the medaka Oryzias latipes, causes pigments to be absent from the whole body and has a transparent body in the adult stage as well as during embryonic stages. To establish a standard table of growth stages for this model fish, morphological features were examined during the growing period from hatching to adulthood. The main observations were performed on morphological changes in external and internal organs that could be seen through the body wall of the living fish during growth. Finally, five growth stages from just after hatching to the adult stage were defined on the basis of synchronized or definite changes in morphology as follows: (1) stage 40 in which the nodes (joints) in bony rays of the caudal and pectoral fins first appear, (2) the stage 41 in which the ribs and the anal, dorsal and ventral fins are formed by degeneration of the membrane fin folds, as recognized by the first appearance of nodes in the fin rays of the anal, pectoral and dorsal fins, and the parallel distribution of the dorsal artery and ventral vein of the tail, (3) stage 42 in which the 2-spiral pattern of the gut, the ray nodes in the ventral fins, and the scales first appear, (4) stage 43 in which early secondary sexual characters such as urinogenital protruberances (female) and papillar processes (male) appear, (5) stage 44 in which the 3-spiral pattern of the gut and the papillar process on the 2nd ray of pectral fins (male) appear.

    Colloid chemistry (kappa o lambda lambda alpha: glue, or gelatin) was introduced in 1861 after the discovery of protoplasm which exhibits gelatin-like properties. Some 80 years later, colloid chemistry (and with it, the concept of protoplasm) was largely abandoned. The membrane (pump) theory, according to which cell water and cell solute like K+ are free as in a dilute KCl solution, became dominant. Later studies revealed that rejecting the protoplasmic approach to cell physiology was not justified. Evidence against the membrane (pump) theory, on the other hand, has stood the test of time. In a new theory of the living cell called the association-induction (AI) hypothesis, the three major components of the living cell (water, proteins and K+) are closely associated; together they exist in a high-(negative)-energy-low entropy state called the living state. The bulk of cell water is adsorbed as polarized multilayers on some fully extended protein chains, and K+ is adsorbed singly on beta- and gamma-carboxyl groups carried on aspartic and glutamic residues of cell proteins. Extensive evidence in support of the AI hypothesis is reviewed. From an extension of the basic concepts of the AI hypothesis and the new knowledge on primary structure of the proteins, one begins to understand at long last what distinguishes gelatin from other proteins; in this new light, new definitions of protoplasm and of colloid chemistry have been introduced. With the return of the concept of protoplasm, living structure takes on renewed significance, linking cell anatomy to cell physiology. Finally, evidence is presented showing that electron microscopists have come close to seeing cell structure in its living state. PMID:1462129

  9. Health and impact assessment: Are we seeing closer integration?

    SciTech Connect

    Morgan, Richard K.

    2011-07-15

    Health has always had a place in wider impact assessment activities, from the earliest days of the National Environmental Policy Act in the United States. However, early thinking tended to focus on health protection and environmental health issues, especially in relation to the effects of pollution. The adoption of wider models of health was reflected in impact assessment circles from the early 1990s, with particular emphasis on an integrated approach to impact assessment, especially at the project level, which would see health impact assessment benefiting from working with other forms of impact assessment, such as social and ecological. Yet twenty years later, integration still seems a distant prospect in many countries. In this paper I examine the case for integrating health considerations within the wider IA process, discuss some of the problems that have historically restricted progress towards this end, and explore the degree to which impact assessment practitioners have been successful in seeking to improve the consideration of health in IA. In New Zealand, project-level impact assessment is based on an integrated model under the Resource Management Act. In addition, HIA was recognised in the early 1990s as a valuable addition to the toolkit for project assessment. Since then policy-level HIA has grown supported by extensive capacity building. If health is being integrated into wider impact assessment, it should be happening in New Zealand where so many enabling conditions are met. Three major project proposals from New Zealand are examined, to characterise the broad trends in HIA development in New Zealand in the last ten years and to assess the degree to which health concerns are being reflected in wider impact assessments. The findings are discussed in the context of the issues outlined in the early part of the paper.

  10. Designing the SALT facility to minimize dome seeing effects

    2003-02-01

    Aspects of the design and experience of the Hobby-Eberly Telescope (HET) were incorporated in the SALT facility design. The characteristics of the local environment were taken into account to ensure a building that is cost effective and functional. The effect of heat from the control room and other warm areas were studied and their locations changed to limit thermal effects. A steel false floor, incorporating forced ventilation and extending around the telescope azimuth pier, was installed. This prevents heat radiating from large concrete surfaces with temperatures potentially higher than ambient. Because site testing (i.e. micro thermal measurements) indicated high turbulence within ~5 m of the ground level, the telescope and pier were raised to improve dome seeing. The SALT site is significantly windy all year round (median velocity = 4.8 m/s), and this was utilized to design better ventilation of the facility using adjustable louvers for natural ventilation. Results of a computational fluid dynamic analysis (CFD) are presented which show an adequate temperature distribution at wind speeds as low as 0.5 m/s. The telescope chamber and dome are build out of insulation panels to ensure low thermal losses during the day when the chamber is air conditioned and thus limit electricity consumption and thermal gradients. Large equipment that emit heat or vibration are housed in a separate utility building 50 m from the telescope in the non-prevailing wind direction in order to limit their effect on the telescope. Vented air from the building is also released at this site.

    One of the most promising and challenging future uses of head-mounted displays (HMDs) is in applications where virtual environments enhance rather than replace real environments. To obtain an enhanced view of the real environment, the user wears a see-through HMD to see 3D computer-generated objects superimposed on his/her real-world view. This see-through capability can be accomplished using either an optical or a video see-through HMD. We discuss the tradeoffs between optical and video see-through HMDs with respect to technological, perceptual, and human factors issues, and discuss our experience designing, building, using, and testing these HMDs.

    Everyone has their own unique version of the visual world and there has been growing interest in understanding the way that personality shapes one’s perception. Here, we investigated meaningful visual experiences in relation to the personality dimension of schizotypy. In a novel approach to this issue, a non-clinical sample of subjects (total n = 197) were presented with calibrated images of scenes, cartoons and faces of varying visibility embedded in noise; the spatial properties of the images were constructed to mimic the natural statistics of the environment. In two experiments, subjects were required to indicate what they saw in a large number of unique images, both with and without actual meaningful structure. The first experiment employed an open-ended response paradigm and used a variety of different images in noise; the second experiment only presented a series of faces embedded in noise, and required a forced-choice response from the subjects. The results in all conditions indicated that a high positive schizotypy score was associated with an increased tendency to perceive complex meaning in images comprised purely of random visual noise. Individuals high in positive schizotypy seemed to be employing a looser criterion (response bias) to determine what constituted a ‘meaningful’ image, while also being significantly less sensitive at the task than those low in positive schizotypy. Our results suggest that differences in perceptual performance for individuals high in positive schizotypy are not related to increased suggestibility or susceptibility to instruction, as had previously been suggested. Instead, the observed reductions in sensitivity along with increased response bias toward seeing something that is not there, indirectly implicated subtle neurophysiological differences associated with the personality dimension of schizotypy, that are theoretically pertinent to the continuum of schizophrenia and hallucination-proneness.

  16. Hubble Sees Material Ejected From Comet Hale-Bopp

    NASA Technical Reports Server (NTRS)

    1995-01-01

    These NASA Hubble Space Telescope pictures of comet Hale-Bopp show a remarkable 'pinwheel' pattern and a blob of free-flying debris near the nucleus. The bright clump of light along the spiral (above the nucleus, which is near the center of the frame) may be a piece of the comet's icy crust that was ejected into space by a combination of ice evaporation and the comet's rotation, and which then disintegrated into a bright cloud of particles.

    Although the 'blob' is about 3.5 times fainter than the brightest portion at the nucleus, the lump appears brighter because it covers a larger area. The debris follows a spiral pattern outward because the solid nucleus is rotating like a lawn sprinkler, completing a single rotation about once per week.

    Ground-based observations conducted over the past two months have documented at least two separate episodes of jet and pinwheel formation and fading. By coincidence, the first Hubble images of Hale-Bopp, taken on September 26, 1995, immediately followed one of these outbursts and allow researchers to examine it at unprecedented detail. For the first time they see a clear separation between the nucleus and some of the debris being shed. By putting together information from the Hubble images and those taken during the recent outburst using the 82 cm telescope of the Teide Observatory (Tenerife, Canary Islands, Spain), astronomers find that the debris is moving away from the nucleus at a speed (projected on the sky) of about 68 miles per hour (109 kilometers per hour).

    The Hubble observations will be used to determine if Hale-Bopp is really a giant comet or rather a more moderate-sized object whose current activity is driven by outgassing from a very volatile ice which will 'burn out' over the next year. Comet Hale-Bopp was discovered on July 23, 1995 by amateur astronomers Alan Hale and Thomas Bopp. Though this comet is still well outside the orbit of Jupiter (almost 600 million miles, or one billion kilometers from Earth

    to that from a more traditional dish style telescope with a diameter of 70 feet. The antenna design, which resembles a household ceiling fan, with blades that have drooped down at an angle of 45 degrees, was conceived to allow the array to see the full sky and cover a wide range of frequencies with a single antenna "The sophisticated digital electronics used in the LWDA allow it to change observing frequency or point in a new direction in an instant, and even allow it to look in two directions at the same time," says Dr. Paul Ray, an astrophysicist at NRL who is overseeing the overall performance of the LWDA. When completed, the LWA will operate in a similar manner, but on a much grander scale. Plans call for over 13,000 individual antennas, divided into 50 stations. These stations will be spread over a 250-mile area across New Mexico, and possibly beyond. Dr. Ray explains, "With so many antennas required for the final LWA, it is vital that we have a testbed on which we can demonstrate the performance of a small number of them before construction of the full LWA begins in earnest." NRL's LWDA serves this purpose, allowing the astronomers and engineers to test the dipole antennas and related computer hardware and software on a small scale, before embarking on construction. The LWA, funding for which is managed by the Office of Naval Research, is a project of the Southwest Consortium, led by the University of New Mexico, and including NRL, ARL:UT, and Los Alamos National Laboratory, with important contributions from Virginia Tech and cooperation from the National Radio Astronomy Observatory (NRAO). The NRAO is a facility of the National Science Foundation operated under cooperative agreement by Associated Universities, Inc.

  18. ISO sees the pattern in the cosmic wallpaper

    NASA Astrophysics Data System (ADS)

    1998-07-01

    Two dozen distant galaxies that are undergoing a process of intense evolution --either merging to build larger ones or reaching their final shape-- have been detected by a team of French astronomers using the European Space Agency's ISO space telescope. These are the first individual objects known to contribute their energy to the bulk of the Cosmic Infrared Background, a radiation that fills the entire universe like a wallpaper, emitted at the era when galaxies were formed. The new-found distant galaxies are indeed like the 'pattern' in this 'cosmic wallpaper'. This discovery will for the first time enable scientists to test different theories of galaxy formation, and therefore to tackle a key problem of astronomy --the birth process of galaxies which has remained a mystery so far, mainly because current telescopes cannot reach that far back in time, about 12,000 million years ago. This obstacle has been partially overcome by the French team headed by Jean-Loup Puget, at the Institut d'Astrophysique Spatiale in Paris, precisely because they searched for the primeval galaxies by focusing first on the study of the cosmic wallpaper, the 'Cosmic Infrared Background' (see note to editors below). This background glow that fills the whole universe is a by-product of the galaxy formation itself, a relic of the era when the first galaxies were being born. Its existence was predicted three decades ago and it was known to be detectable only at infrared wavelengths, as the dust enshrouding young galaxies causes them to be both opaque in visible light but bright at infrared wavelengths. However, this cosmic wallpaper turned out to be very dim: only two years ago Puget's team detected it after a careful analysis of data from NASA's COBE satellite. Once the 'Cosmic Infrared Background' had been found, the next step was to disentangle it into the sources contributing to it, that is, into the young galaxies in evolution or the 'pattern' in the wallpaper. The two dozen distant

  19. Proyecto para la medición sistemática de seeing en CASLEO

    NASA Astrophysics Data System (ADS)

    Fernández Lajus, E.; Forte, J. C.

    La calidad del seeing astronómico es ciertamente uno de los parámetros mas importantes que caracterizan el sitio de un observatorio. Por tanto se desea determinar si el alto valor de seeing observado con el telescopio de 2.15 m se debe a efectos internos y/o del entorno a la cupula o si se debe simplemente al seeing propio del lugar. El actual mecanismo de refrigeración del espejo primario del 2.15, parece haber mejorado notablemente la calidad del seeing. Sin embargo se hace necesario saber hasta que punto el valor del seeing puede ser mejorado. La primera etapa del proyecto consistió en la puesta a punto del telescopio emplazado para este propósito y la adquisición de las primeras medidas tentativas de seeing.

  20. Comparative Solar Seeing and Scintillation Studies at the Fuxian Lake Solar Station

    NASA Astrophysics Data System (ADS)

    Zhong, Liu; Beckers, Jacques M.

    2001-01-01

    Starting November 1999 we are carrying out simultaneous seeing observations with the Solar Differential Image Motion Monitor (S-DIMM) at the Fuxian Lake station of the Yunnan Observatory and a solar scintillometer of the type used in the recent site survey by one of us (Beckers et al., 1997). The purpose was to compare the two methods of assessing the daytime atmospheric seeing for a lake site. We report here the first results of this comparison. We find that the relation between the seeing as measured by the S-DIMM (the Fried parameter r 0) and the scintillation in the solar irradiance (σI) differs greatly from the relation found by Seykora (1993) for NSO/Sac Peak. We conclude that the σI measurements give a good indication for the amount of near-Earth seeing but that they are a poor proxy for the total atmospheric seeing. We interpret the simultaneous ( r 0, σI) observations in terms of an atmospheric seeing model and find good quantitative agreement with a model in which a fraction (α) of the seeing originated near the Earth (ground or water) and the rest (1-α) originates at higher layers. For lake sites α is small all day and the seeing is determined primarily by the refractive index variations at higher atmospheric layers. For land sites α is small in the early morning but rapidly increases as the day progresses, near-Earth seeing dominating there most of the time.

  2. On the Difference between Seeing and Image Quality: When the Turbulence Outer Scale Enters the Game

    NASA Astrophysics Data System (ADS)

    Martinez, P.; Kolb, J.; Sarazin, M.; Tokovinin, A.

    2010-09-01

    We attempt to clarify the frequent confusion between seeing and image quality for large telescopes. The full width at half maximum of a stellar image is commonly considered to be equal to the atmospheric seeing. However the outer scale of the turbulence, which corresponds to a reduction in the low frequency content of the phase perturbation spectrum, plays a significant role in the improvement of image quality at the focus of a telescope. The image quality is therefore different (and in some cases by a large factor) from the atmospheric seeing that can be measured by dedicated seeing monitors, such as a differential image motion monitor.

  14. Conservation of the Ustilago maydis effector See1 in related smuts

    PubMed Central

    Redkar, Amey; Villajuana- Bonequi, Mitzi; Doehlemann, Gunther

    2015-01-01

    Ustilago maydis is a biotrophic fungus that induces formation of tumors in maize (Zea mays L). In a recent study we identified See1 (Seedling efficient effector 1) as an U. maydis organ-specific effector required for tumor formation in leaves. See1 is required for U. maydis induced reactivation of plant DNA synthesis during leaf tumor progression. The protein is secreted from biotrophic hyphae and localizes to the cytoplasm and nucleus of plant cell. See1 interacts with maize SGT1, a cell cycle and immune regulator, interfering with its MAPK-triggered phosphorylation. Here, we present new data on the conservation of See1 in other closely related smuts and experimental data on the functionality of See1 ortholog in Ustilago hordei, the causal agent of barley covered smut disease.

  16. Volcano-tectonic structures and CO2-degassing patterns in the Laacher See basin, Germany

    NASA Astrophysics Data System (ADS)

    Goepel, Andreas; Lonschinski, Martin; Viereck, Lothar; Büchel, Georg; Kukowski, Nina

    2015-07-01

    The Laacher See Volcano is the youngest (12,900 year BP) eruption center of the Quarternary East-Eifel Volcanic Field in Germany and has formed Laacher See, the largest volcanic lake in the Eifel area. New bathymetric data of Laacher See were acquired by an echo sounder system and merged with topographic light detection and ranging (LiDAR) data of the Laacher See Volcano area to form an integrated digital elevation model. This model provides detailed morphological information about the volcano basin and results of sediment transport therein. Morphological analysis of Laacher See Volcano indicates a steep inner crater wall (slope up to 30°) which opens to the south. The Laacher See basin is divided into a deep northern and a shallower southern part. The broader lower slopes inclined with up to 25° change to the almost flat central part (maximum water depth of 51 m) with a narrow transition zone. Erosion processes of the crater wall result in deposition of volcaniclastics as large deltas in the lake basin. A large subaqueous slide was identified at the northeastern part of the lake. CO2-degassing vents (wet mofettes) of Laacher See were identified by a single-beam echo sounder system through gas bubbles in the water column. These are more frequent in the northern part of the lake, where wet mofettes spread in a nearly circular-shaped pattern, tracing the crater rim of the northern eruption center of the Laacher See Volcano. Additionally, preferential paths for gas efflux distributed concentrically inside the crater rim are possibly related to volcano-tectonic faults. In the southern part of Laacher See, CO2 vents occur in a high spatial density only within the center of the arc-shaped structure Barschbuckel possibly tracing the conduit of a tuff ring.

    Since e-mail generates itself on a round-the-clock, daily basis, it's not unusual for me to receive an average of fifty e-mails a day, or more than 300 a week. That s a lot of e-mail. I have spoken with many of my fellow project managers about my relationship with e-mail. In my case, reading and responding to it is a temptation almost too hard to resist. When I receive an e-mail I tend to want to stop everything I m doing, and open and answer it. Indeed, in my life you could say e-mail is a force to be reckoned with. Interestingly, my fascination with mail began a long time ago. I trace it back to my days as a young boy when I started receiving my first letters from friends and family. Walking home from school, I was often filled with curiosity, wondering if I had received any mail that day. In college, I knew the exact time the mail was delivered, and I headed for my mailbox as close to that hour as I could. After that, I served in an Army Reserve Post Office Unit, where I came to realize how important a postal unit was to the military. There were many others like myself, far from home, who relied on the written word to stay connected to the people in their lives. Over the years I have changed in many ways, and so has the mail. But the same sense of connection, and the same urge to respond to someone who has written me, remains. The 24/7 nature of e-mail has compounded the situation. It is relentless in its pursuit of my time and attention-and, as such, e-mail has become something I have had to manage in a variety of situations

  20. Seeing Color

    Colors are powerful tools for engaging children, from the youngest years onward. We hang brightly patterned mobiles above their cribs and help them learn the names of colors as they begin to record their own ideas in pictures and words. Colors can also open the door to an invisible world of electromagnetism, even when children can barely imagine…

    Mammals generally have colour vision inferior to that of other vertebrates. This is partially redressed in primates, but the underlying mechanisms differ in Old World and New World primate groups. How has this occurred and what were the key events in the molecular evolution of primate colour vision? PMID:11313537

    Previous research has shown that young children deny being able to see an agent whose eyes are covered. The current study explored this phenomenon further. In Experiment 1, 3-year-olds denied that they could "see," but affirmed that they could "look at," a doll whose eyes were covered--indicating that they demand mutuality for seeing another but not for looking at another. In Experiment 2, 3.5-year-olds drew the same distinction between "see" and "look at" when facing a doll or a human. A strong correlation between children's knowledge of the reciprocal pronoun "each other" and their adherence to the mutuality demand was found. The results are discussed with respect to children's bias for second personal encounters and children's relational concept of persons. PMID:25558861

  6. The education of an astronomical maverick: T. J. J. See and the University of Missouri

    The educational background of the controversial astronomer Thomas Jefferson Jackson See is recounted. See failed in successive employment and research opportunities; coworkers and superiors apparently were repelled by his intense egotism, his inability to work with others, his refusal to operate within established codes of conduct, and questions arising from both the source and the reliability of his scientific work. See's approach to his scientific career was shaped, to a large degree, by his undergraduate education, and the professional turmoil of his later life was paralleled by his tumultuous career as a student at the University of Missouri, which included bitter political infighting and accusations of plagiarism. Combined with a tendency to make fundamental errors in both observational and theoretical research, See's flaws ultimately cost him his scientific credibility and destroyed his professional career and reputation.
