William Harvey's discovery of the circulation of the blood is often described as a product of the Scientific Revolution of the Seventeenth Century. Modern research has, however, shown thatHarvey followed the Aristotelian research tradition and thus tried to reveal the purpose of the organs through examination of various animals. His publication of 1628 has to be read as an argument of natural philosophy, or, more precisely, as a series of linked observations, experiments and philosophical reasonings from which the existence of circulation has to be deduced as a logical consequence. Harvey did not consider experiments as superior to philosophical reasoning nor intended he to create a new system of medicine. He believed in the vitality of the heart and the blood and rejected Francis Bacon's empirism and the mechanistic rationalism of Descartes. Harvey's contribution and originality lied less in his single observations and experiments but in the manner how he linked them with critical reasoning and how he accepted, presented and defended the ensuing radical findings.

William Harvey, Aristotle and astrology.
Gregory, Andrew
2014-06-01
In this paper I argue that William Harvey believed in a form of astrology. It has long been known that Harvey employed a macrocosm-microcosm analogy and used alchemical terminology in describing how the two types of blood change into one another. This paper then seeks to examine a further aspect of Harvey in relation to the magical tradition. There is an important corollary to this line of thought, however. This is that while Harvey does have a belief in astrology, it is strongly related to Aristotle's views in this area and is quite restricted and attenuated relative to some contemporary beliefs in astrology. This suggests a more general thesis. While Harvey was amenable to ideas which we associate with the natural magic tradition, those ideas had a very broad range of formulation and there was a limit to how far he would accept them. This limit was largely determined by Harvey's adherence to Aristotle's natural philosophy and his Christian beliefs. I argue that this is also the case in relation to Harvey's use of the macrocosm-microcosm analogy and of alchemical terminology, and, as far as we can rely on the evidence, this informs his attitudes towards witches as well. Understanding Harvey's influences and motives here is important in placing him properly in the context of early seventeenth-century thought.

William Harvey's discovery of the presence of capillaries and the role played by them without actually seeing them highlights his power of observation and logic. However, his perspective could not be considered as new since he had adopted his disposition for ocular demonstration from Aristotle and Galen.

A dark business, full of shadows: analogy and theology in William Harvey.
Goldberg, Benjamin
2013-09-01
In a short work called De conceptione appended to the end of his Exercitationes de generatione animalium (1651), William Harvey developed a rather strange analogy. To explain how such marvelous productions as living beings were generated from the rather inauspicious ingredients of animal reproduction, Harvey argued that conception in the womb was like conception in the brain. It was mostly rejected at the time; it now seems a ludicrous theory based upon homonymy. However, this analogy offers insight into the structure and function of analogies in early modern natural philosophy. In this essay I hope to not only describe the complex nature of Harvey's analogy, but also offer a novel interpretation of his use of analogical reasoning, substantially revising the account offered by Guido Giglioni (1993). I discuss two points of conceptual change and negotiation in connection with Harvey's analogy, understanding it as both a confrontation between the border of the natural and the supernatural, as well as a moment in the history of psychology. My interpretation touches upon a number of important aspects, including why the analogy was rejected, how Harvey systematically deployed analogies according to his notions of natural philosophical method, how the analogy fits into contemporary discussions of analogies in science, and finally, how the analogy must be seen in the context of changing Renaissance notions of the science of the soul, ultimately confronting the problem of how to understand final causality in Aristotelian science. In connection with the last, I conclude the essay by turning to how Harvey embeds the analogy within a natural theological cosmology. Copyright © 2013. Published by Elsevier Ltd.

Andreas Vesalius is often regarded as the founding father of modern anatomical study. The quincentennial anniversary of his birth - 31 December 2014 - has been very widely commemorated, and it is the purpose of this article to contrast these celebrations with what happened during the Vesalius quatercentenary year of 1914. More specifically, we look at how Vesalius was perceived a century ago by examining his influence on two of western medicine's most iconic gentlemen - Harvey Williams Cushing (1869-1939) and his larger than life mentor, Sir William Osler (1849-1919).

Epigenesis and the rationality of nature in William Harvey and Margaret Cavendish.
Goldberg, Benjamin
2017-06-01
The generation of animals was a difficult phenomenon to explain in the seventeenth century, having long been a problem in natural philosophy, theology, and medicine. In this paper, I explore how generation, understood as epigenesis, was directly related to an idea of rational nature. I examine epigenesis-the idea that the embryo was constructed part-by-part, over time-in the work of two seemingly dissimilar English philosophers: William Harvey, an eclectic Aristotelian, and Margaret Cavendish, a radical materialist. I chart the ways that they understood and explained epigenesis, given their differences in philosophy and ontology. I argue for the importance of ideas of harmony and order in structuring their accounts of generation as a rational process. I link their experiences during the English Civil war to how they see nature as a possible source for the rationality and concord sorely missing in human affairs.

Blood money: Harvey's De motu cordis (1628) as an exercise in accounting.
Neuss, Michael J
2018-04-13
William Harvey's famous quantitative argument from De motu cordis (1628) about the circulation of blood explained how a small amount of blood could recirculate and nourish the entire body, upending the Galenic conception of the blood's motion. This paper argues that the quantitative argument drew on the calculative and rhetorical skills of merchants, including Harvey's own brothers. Modern translations of De motu cordis obscure the language of accountancy that Harvey himself used. Like a merchant accounting for credits and debits, intake and output, goods and moneys, Harvey treated venous and arterial blood as essentially commensurate, quantifiable and fungible. For Harvey, the circulation (and recirculation) of blood was an arithmetical necessity. The development of Harvey's circulatory model followed shifts in the epistemic value of mercantile forms of knowledge, including accounting and arithmetic, also drawing on an Aristotelian language of reciprocity and balance that Harvey shared with mercantile advisers to the royal court. This paper places Harvey's calculations in a previously underappreciated context of economic crisis, whose debates focused largely on questions of circulation.

In this paper I address the issue of the theoretical and epistemological status of embryology at the rise of the so-called "Scientific Revolution" (also in the first half of the seventeenth-century) and raise the question, in what sense and to what extent the historiographical concept of "Scientific Revolution" is applicable to the domain of embryology. To achieve this aim I compare the theories of three protagonists of the medical, scientific and philosophical debate of that age, namely Cesare Cremonini, William Harvey and René Descartes, who had very different views on the world structure and human nature and a very different concept of science, but who shared, as concerns embryological issues, an epigenetic conception of the development of the embryo. Their theories are discussed and compared in light of following questions: 1) What do Cremonini's, Harvey's and Descartes's embryological theories exactly aim to?; 2) In developing their theories, do these thinkers deal explicitly or implicitly with the Aristotelian and the Galenic embryological paradigm?; 3)Do they refer polemically to the Aristotelian and the Galenic tradition and what theoretical and/or rhetorical function have these polemical references?; 4) Do the embryological theories of Cremonini, Harvey and Descartes reflect the century-long dispute between "(Aristotelian) philosophers" and "(Galenic) doctors"?; 5) How is represented embryology as a 'scientific' and/or 'theoretical' domain? And what relationship between concepts of 'truth', 'research', 'tradition' and 'scientific progress' is implied or proposed in the embryological works of these three thinkers? What kind of use do Cremonini, Harvey and Descartes make of the argumenta ex ratione and of those ex experientia?

William Harvey's writings betray amazing insights born out of countless hours of thoughtful experimentation. Throughout his life, Harvey worked as a tireless and thoughtful researcher and a transmitter and intermediary between the ancient Greek natural philosophers and physicians and the "moderns," for whom he founded two forward-looking, interlinked sciences: modern physiology and nascent cardiology. Harvey's methodology and demonstrations were of such fundamental and standardizing nature as to secure the sure progress of these two sciences. Thus, he rendered to them such a service as Descartes's cogito ergo sum furnished to Philosophy in giving it a rational standard of certainty, for want of which the more speculative minds of that era were inundated with extraordinary conjectures. If Harvey disproved Galen, he absorbed and continued in his physiologic research many a principle from Aristotle, whose supreme disciple he remains. The guidance and authority of Aristotle were strong with him to the end. Harvey's account of the motions of the heart and blood in the circulation demonstrated that complex physiological systems can be represented in straightforward mechanical terms, a concept which has remained fundamental to the present day. The philosophical implication of William Harvey's discovery of the circulation of the blood was the resolute application of the experimental method to cardiology. In my judgment, he established today's forward-looking discipline of translational cardiovascular research. In due course, he should be widely acknowledged to have done so. © 2013 Elsevier Ireland Ltd. All rights reserved.

Tsukisawa, M
1995-01-01
In De motu cordis, W. Harvey sometimes waxes lyrical on the primacy of the heart. In his another treatise, De generatione, however, he insists on the primacy of the blood. The "conversion theory" explained this discrepancy with Harvey's conversion as caused by his discovery of the antiquity of the blood. But Whitterridge showed that Harvey had already described the antiquity of the blood in his earliest notebook, Prelectiones. As shown in this article, Harvey's observation was not a mere accidental discovery; based on the "classic questions", it was continuously and persistently conducted until he was assured of having seen the blood to exist prior to the pulse and movement to occur in the blood. While this crucial observation was not yet made in Prelectiones and De motu cordis, it was described as crucial evidence of the theory of the primacy of the blood in De generatione, in which this new theory was introduced as an independent topic of the exercitatio. The topic of the order of the generation was a crucial issue in the theoretical medicine of Harvey's days. That is, the Aristotelian primacy of the heart had been seriously challenged by the Galenic tripartite theory which pursued the antiquity of three organs. Harvey's theory, or the primacy of the blood, seems to consists with Aristotle's premise, in that it asserts the existance of the only source of all functions in living animals. Harvey's theory, however, was confronted, on the other hand, with Aristotle's another inconsistency, namely, the issue of two definitions about anima. We must consider the construction and strategy of the exercitatio in Harvey's days to understand the exact meaning of the primacy of the heart in De motu cordis. In De motu cordis, Harvey did not use the primacy of the heart in a central part of the exercitatio, namely, in confirming his unprecedented theory, the circulation of the blood, but he settled this Aristotelian premise in a marginal part, namely, in ratiocinating the final

Harvey Cushing, the spine surgeon: the surgical treatment of Pott disease.
Bydon, Ali; Dasenbrock, Hormuzdiyar H; Pendleton, Courtney; McGirt, Matthew J; Gokaslan, Ziya L; Quinones-Hinojosa, Alfredo
2011-08-01
Review of historical archival records. Describe Harvey Cushing's patients with spinal pathology. Harvey Cushing was a pioneer of modern surgery but his work on spine remains largely unknown. Review of the Chesney Medical Archives of the Johns Hopkins Hospital from 1896 to 1912. This is the first time that Cushing's spinal cases while he was at the Johns Hopkins Hospital, including those with Pott disease, have been described.Cushing treated three young men with psoas abscesses secondary to Pott disease during his residency: he drained the abscesses, debrided any accompanying necrotic vertebral bodies, irrigated the cavity with salt, and left the incision open to close by secondary intention. Although Cushing used Koch's "tuberculin therapy" (of intravenous administration of isolated tubercular bacilli) in one patient, he did not do so in the other two, likely because of the poor response of this first patient. Later in his tenure, Cushing performed a laminectomy on a patient with kyphosis and paraplegia secondary to Pott disease. These cases provide a view of Cushing early in his career, pointing to the extraordinary degree of independence that he had during his residency under William Steward Halsted; these cases may have been important in the surgical upbringing both of Cushing and his coresident, William Stevenson Baer, who became the first professor of Orthopedics at Johns Hopkins Hospital. At the turn of the last century, Pott disease was primarily treated by immobilization with bed rest, braces, and plaster-of-paris jackets; some surgeons also employed gradual correction of the deformity by hyperextension. Patients who failed a trial of conservative therapy (of months to years) were treated with a laminectomy. However, the limitations of these strategies led to the development of techniques that form the basis of contemporary spine surgery-instrumentation and fusion.

Performance of Oil Infrastructure during Hurricane Harvey
Bernier, C.; Kameshwar, S.; Padgett, J.
2017-12-01
Three major refining centers - Corpus Christi, Houston, and Beaumont/Port Arthur - were affected during Hurricane Harvey. Damage to oil infrastructure, especially aboveground storage tanks (ASTs), caused the release of more than a million gallons of hazardous chemicals in the environment. The objective of this presentation is to identify and gain a better understanding of the different damage mechanisms that occurred during Harvey in order to avoid similar failures during future hurricane events. First, a qualitative description of the damage suffered by ASTs during Hurricane Harvey is presented. Analysis of aerial imagery and incident reports indicate that almost all spills were caused by rainfall and the associated flooding. The largest spill was caused by two large ASTs that floated due to flooding in the Houston Ship Channel releasing 500,000 gallons of gasoline. The vulnerability of ASTs subjected to flooding was already well known and documented from previous storm events. In addition to flooding, Harvey also exposed the vulnerability of ASTs with external floating roof to extreme rainfall; more than 15 floating roofs sank or tilted due to rain water accumulation on them, releasing pollutants in the atmosphere. Secondly, recent fragility models developed by the authors are presented which allow structural vulnerability assessment of floating roofs during rainfall events and ASTs during flood events. The fragility models are then coupled with Harvey rainfall and flood empirical data to identify the conditions (i.e.: internal liquid height or density, drainage system design and efficiency, etc.) that could have led to the observed failures during Hurricane Harvey. Finally, the conditions causing tank failures are studied to propose mitigation measures to prevent future AST failures during severe storm, flood, or rainfall events.

The region of sky containing the 38 s X-ray pulsar OAO 1657 - 415 has been observed on March 1990 with Sigma, an imaging gamma-ray telescope exploiting the coded mask technique. This observation has yielded an accurate (about arcminute-scale) localization for OAO 1657 - 415 at hard X-ray energy, confirming its association with a previously suggested soft X-ray candidate. A timing analysis of the 40-120 keV data has revealed for the first time a spin-down episode in OAO 1657 - 415, implying that an important change in the accretion torque experienced by this X-ray pulsar must have recently occurred. 18 refs

SEKULARISASI DALAM PANDANGAN HARVEY COX
Directory of Open Access Journals (Sweden)
Fauzan Fauzan
2017-02-01
Full Text Available Sebagian besar kaum agamawan (ortodoks memandang sekularisasi sebagai ancaman terhadap eksistensi agama. Namun sebaliknya, Harvey Cox memandang sekularisasi sebagai teologi perubahan sosial yang bertujuan mendobrak kebuntuan agama yang terbelenggu oleh ide “pemeliharaan” dan “kemapanan”. Tulisan ini membahas pandangan Harvey Cox tentang sekularisasi, konsepnya tentang Kota Sekuler (Secular City, dan Tuhan pada masyarakat sekuler. Cox melihat sekularisasi merupakan sebuah keniscayaan sejarah. Sekularisasi merupakan gerakan yang membebaskan manusia dari dogma yang membelenggu kebebasan manusia. Melalui simbol Kota Sekuler, Cox menghadirkan paradigma teologi yang lebih sesuai dengan keadaan masyarakat modern saat ini. Cox melihat bahwa Tuhan sebagaimana yang diajarkan oleh Kristiani –juga agama lain– bukanlah Tuhan yang sebenarnya. Tuhan tak lebih dari sebuah penamaan yang kehadirannya terkadang kosong dan ambigu. Semenjak penamaan dilekatkan dalam lingkungan sosio kultural tertentu, maka kata “Tuhan” tidak suci lagi. Apabila Tuhan dimaknai secara “ketat” dalam ruang tradisi yang berbeda-beda, maka akan terjadi benturan yang terkadang membutuhkan pengorbanan jiwa.

Estimating the human influence on Hurricanes Harvey, Irma and Maria
Wehner, M. F.; Patricola, C. M.; Risser, M. D.
2017-12-01
Attribution of the human-induced climate change influence on the physical characteristics of individual extreme weather events has become an advanced science over the past decade. However, it is only recently that such quantification of anthropogenic influences on event magnitudes and probability of occurrence could be applied to very extreme storms such as hurricanes. We present results from two different classes of attribution studies for the impactful Atlantic hurricanes of 2017. The first is an analysis of the record rainfall amounts during Hurricane Harvey in the Houston, Texas area. We analyzed observed precipitation from the Global Historical Climatology Network with a covariate-based extreme value statistical analysis, accounting for both the external influence of global warming and the internal influence of ENSO. We found that human-induced climate change likely increased Hurricane Harvey's total rainfall by at least 19%, and likely increased the chances of the observed rainfall by a factor of at least 3.5. This suggests that changes exceeded Clausius-Clapeyron scaling, motivating attribution studies using dynamical climate models. The second analysis consists of two sets of hindcast simulations of Hurricanes Harvey, Irma, and Maria using the Weather Research and Forecasting model (WRF) at 4.5 km resolution. The first uses realistic boundary and initial conditions and present-day greenhouse gas forcings while the second uses perturbed conditions and pre-industrial greenhouse has forcings to simulate counterfactual storms without anthropogenic influences. These simulations quantify the fraction of Harvey's precipitation attributable to human activities and test the super Clausius-Clapeyron scaling suggested by the observational analysis. We will further quantify the human influence on intensity for Harvey, Irma, and Maria.

Monitoring and Mapping the Hurricane Harvey Flooding in Houston, Texas.
Balaji Bhaskar, M. S.
2017-12-01
Monitoring and Mapping the Hurricane Harvey Flooding in Houston, Texas.Urban flooding is a hazard that causes major destruction and loss of life. High intense precipitation events have increased significantly in Houston, Texas in recent years resulting in frequent river and bayou flooding. Many of the historical storm events such as Allison, Rita and Ike have caused several billion dollars in losses for the Houston-Galveston Region. A category 4 Hurricane Harvey made landfall on South Texas resulting in heavy precipitation from Aug 25 to 29 of 2017. About 1 trillion gallons of water fell across Harris County over a 4-day period. This amount of water covers Harris County's 1,800 square miles with an average of 33 inches of water. The long rain event resulted in an average 40inch rainfall across the area in several rain gauges and the maximum rainfall of 49.6 inches was recorded near Clear Creek. The objectives of our study are to 1) Process the Geographic Information System (GIS) and satellite data from the pre and post Hurricane Harvey event in Houston, Texas and 2) Analyze the satellite imagery to map the nature and pattern of the flooding in Houston-Galveston Region. The GIS data of the study area was downloaded and processed from the various publicly available resources such as Houston Galveston Area Council (HGAC), Texas Commission of Environmental Quality (TCEQ) and Texas Natural Resource Information Systems (TNRIS). The satellite data collected soon after the Harvey flooding event were downloaded and processed using the ERDAS image processing software. The flood plain areas surrounding the Brazos River, Buffalo Bayou and the Addicks Barker reservoirs showed severe inundation. The different watershed areas affected by the catastrophic flooding in the wake of Hurricane Harvey were mapped and compared with the pre flooding event.

It is commonly believed that storm surge is the most destructive aspect of hurricanes. However, massive rainfall with a return period of 100 years or more induced by hurricanes can cause more catastrophic damage than losses caused by storm surge as demonstrated recently by hurricanes Harvey, Irma and Maria. In this study the hydrodynamics and environmental effects of hurricanes Ike and Harvey were compared and contrasted by linking hydrodynamic flow models with water quality models to simulate spills from storage tanks located in the Houston Ship Channel (HSC). Hurricane Ike with a maximum surge of 5.3 meters in Galveston Bay and Harvey with a maximum rainfall of 1.25 meters both struck the HSC region in Texas in 2008 and 2017, respectively. Both events resulted in numerous spills from municipal and industrial facilities, hazardous waste sites, superfund sites, and landfills. The Environmental Fluid Dynamic Code (EFDC) was coupled with the SWAN+ADCIRC hurricane simulation model to simulate Hurricane Ike and EFDC was coupled with USGS flow boundary conditions to model Hurricane Harvey. A conservative dye release was used to simulate a chemical release during each event. The results showed Hurricane Harvey caused higher water surface elevations within the HSC accompanied by longer and wider-spread land inundation. In contrast, higher water surface elevations were observed within the shallow side bays during Hurricane Ike that caused sediment resuspension and repartitioning of pollutants. Rapid spill mass transportation was observed for both hurricanes; 50% of total spill mass reached Galveston Bay in 20 and 22 hours after a spill event for Hurricane Harvey and Ike, respectively, and more than 90% of the spill mass reached the bay in 36 and 48 hours, respectively. Unlike Hurricane Harvey, the conservative tracer was spread almost 2.5 km upstream of the releasing point for Hurricane Ike due to surge. However, during Harvey, 35% more land was affected by the spilled

Hurricane Harvey was the first major hurricane to impact the USA in over a decade, making landfall southwest of Houston, TX on August 26, 2017. Although Harvey was downgraded to a tropical storm shortly after landfall, it dropped a record amount of rain and was responsible for epic flooding across much of southeast Texas. While precipitation from a large storm like Harvey can be estimated from in-situ rain gages and Doppler radar, the accompanying surface water changes that lead to flooding are imperfectly observed due to the limited coverage of existing stream and lake level gages and because floodwaters inundate areas that are typically unmonitored. Earth's response to changes in surface loading provides an opportunity to observe the local hydrological response to Hurricane Harvey, specifically the dramatic changes in water storage coincident with and following the storm. Continuous GPS stations in southeastern Texas observed an average drop in land surface elevations of 1.8 cm following Harvey's landfall, followed by a gradual recovery to pre-storm levels over the following month. We interpret this surface motion as Earth's elastic response to the weight of cumulative rainfall during the storm, followed by rebound as that weight was removed by runoff and evapotranspiration (ET). Using observations of surface displacements from GPS stations in the HoustonNET and Plate Boundary Observatory networks, we model the daily water storage changes across Texas and Louisiana associated with Harvey. Because Harvey's barometric pressure low caused surface uplift at the cm level which temporarily obscured the subsidence signal due to precipitation, we model and remove the effect of atmospheric loading from the GPS data prior to our analysis. We also consider the effect on GPS position time series of non-tidal ocean loading due to the hurricane storm surge, which at the coast was an order of magnitude larger than loads due to precipitation alone. Finally, we use our results to

Hurricane Harvey & Houston: Hell or High Water
Bedient, P. B.
2017-12-01
Harvey was the largest rainfall and most damaging flood event in US history. By all measures the widespread impact was a devastating blow to all of Houston and surrounding areas. It dropped between 36 and 52 inches along the Texas coast over 5 days, exceeding all previous rainfall records, with up to 20 inches in a day. However, two earlier events from 2015 and 2016 also brought widespread flooding to many parts of Houston, especially concentrated in a few watersheds. Most bayous during Harvey were over bank by as much as 10 ft, and flooded an estimated 136000 homes in Harris county alone, greatly exceeding the massive TS Allison impact of 2001. While the area deals with a significant recovery effort, there is a massive call to action on the part of politicians, governmental agencies, and those affected by this event. There is need for a better statistical basis of rainfalls and floodplain mapping in Houston. Development patterns and density have come into question, as homes have been either built in 100 yr floodplains or taken into those floodplains over time. Estimates say > 47 % of homes flooded in TS Allison were outside the floodplain. Many homes were built behind Addicks/Barker reservoirs that protect downtown, many with no knowledge that they were in harms way (over 8000 were flooded there alone), and flooded as water reached record setting levels. New technologies have allowed the measurement and prediction of floods to make great strides since the mid 1990s, (Radar, LIDAR, GIS, hydrologic models, floodplain updates) and the Houston area has benefited from these efforts. While the plan going forward is daunting, there are a number of positive steps that are occurring and should lead to more resiliency. There needs to be policy changes on storage and detention requirements, green space & infrastructure improvements, and perhaps a third regional reservoir above Addicks. Also there is a renewed interest in flood warning systems to better inform the public

Discovery of the Orbit of the X-ray pulsar OAO 1657-415
Chakrabarty, Deepto; Grunsfeld, John M.; Prince, Thomas A.; Bildsten, Lars; Finger, Mark H.; Wilson, Robert B.; Fishman, Gerald J.; Meegan, Charles A.; Paciesas, William S.

Timing observations of the 38 s accreting X-ray pulsar OAO 1657-415 made with the BATSE large-area detectors on the Compton Gamma Ray Observatory have revealed a binary orbit with an X-ray eclipse by the stellar companion. From the pulsar mass function fx(M) = 11.7 +/- 0.2 solar masses and the measured eclipse half-angle theta(e) = 29.7 +/- 1.3 deg, we infer that the stellar companion is a supergiant of spectral class B0-B6. If the companion can be identified and its orbital velocity measured, the neutron star mass can be constrained. Both intrinsic spin-up and spin-down of the pulsar were measured during our observation.

Polycyclic aromatic hydrocarbons (PAHs) are complex environmental toxicants. Exposure to them has been linked to adverse health outcomes including cancer, as well as diseases of the skin, liver, and immune system. Based on an ongoing community engagement partnership with stakeholder groups and residents, we conducted a small longitudinal study to assess domestic exposure to PAHs among residents of Manchester, an environmental justice neighborhood located in the East End of Houston, TX. In December, 2016, we used fiber wipes to collect samples of household dust from 25 homes in Manchester. Following Hurricane Harvey, in September 2017, we revisited 24 of the 25 homes to collect soil samples from the front yards of the same homes. Wipes and soil were analyzed for the presence of PAHs using gas chromatography-mass spectrometry (GC-MS) methods. Principal component analysis plots, heatmaps, and PAH ratios were used to compare pre- and post-Hurricane Harvey samples. While direct comparison is not possible, we present three methods for comparing PAHs found in pre-hurricane fiber wipes and post-hurricane soil samples. The methods demonstrate that the PAHs found before and after Hurricane Harvey are likely from similar sources and that those sources are most likely to be associated with combustion. We also found evidence of redistribution of PAHs due to extreme flooding associated with Hurricane Harvey. Residents of the Manchester neighborhood of Houston, TX, are exposed to a range of PAHs in household dust and outdoor soil. While it was not possible to compare directly, we were able to use several methods to assess detected concentrations, changes in site-specific PAH allocations, and PAH origination. Additional research is needed to identify specific sources of domestic PAH exposure in these communities and continued work involving community members and policy makers should aim to develop interventions to reduce domestic exposure to and prevent negative health outcomes

[Williams-Beuren syndrome (Williams syndrome). Case report].
Miklós, Györgyi; Fekete, György; Haltrich, Irén; Tóth, Miklós; Reismann, Péter
2017-11-01
Williams syndrome is a rare genetic disorder, that occurs equally in all ethnic groups and both sexes. The diagnosis might be missed during childhood in mild cases. However, establishing the diagnosis is important, not only to find the cause of intellectual disability but to look for cardiovascular, endocrine, psychiatry, urology and other conditions, which can occur at any age in the patients' lifetime. This case report presents the story of 47-year-old woman, who was admitted with haematemesis. During her stay on the ward, in the light of the distinctive facial features, mental retardation, and social behaviour patterns, the possibility of Williams syndrome emerged. Later, the diagnosis was confirmed by genetic analysis. This female is the oldest living patient with Williams syndrome in Hungary. Orv Hetil. 2017; 158(47): 1883-1888.

The Renaissance Kidney-Nephrology in and about the Sixteenth Century.
Eknoyan, Garabed
2012-07-01
The endeavor to understand the workings of the human body is as old as civilization; but it is in the intellectual movement of the Renaissance that its actual scientific study began in earnest and has not ceased growing since then. It was in the 16th century that the study of organs was launched and with it that of the kidney, which was then conceived as an accessory organ to clear the excess water ingested with food. The study of the structural basis of kidney function was launched by Bartolomeo Eustachio (1514-1574); the elements of its physiology and pathology were promulgated by Jean Fernel (1497-1558), and that of the chemical study of urine and of the principal cause of kidney disease then, calculi, instigated by Joan Baptista Van Helmont (1577-1644). The methodological approaches of these and their contemporary investigators, which were crystallized and formulated by Francis Bacon (1561-1626), opened the gates of the Scientific Revolution that followed in the 17th century, beginning with that of describing the circulation in 1628 by William Harvey (1564-1657) that would finally free the kidney from the shackles imposed on it as a mere accessory organ to the liver in Galen's physiology. © 2012 Wiley Periodicals, Inc.

Hurricane Harvey that made landfall in the southern Texas this August is one of the most destructive hurricanes during the 2017 hurricane season. During its active period, many areas in coastal Texas region received more than 40 inches of rain. This downpour caused significant flooding resulting in about 77 casualties, displacing more than 30,000 people, inundating hundreds of thousands homes and is currently estimated to have caused more than $70 billion in direct damage. One of the significantly affected areas is Harris County where the city of Houston, TX is located. Covering over two HUC-8 drainage basins ( 2702 mi2), this county experienced more than 80% of its annual average rainfall during this event. This study presents an effort to reconstruct flooding caused by extreme rainfall due to Hurricane Harvey in Harris County, Texas. This computationally intensive task was performed at a 30-m spatial resolution using a rapid flood model called Flood2D-GPU, a graphics processing unit (GPU) accelerated model, on Oak Ridge National Laboratory's (ORNL) Titan Supercomputer. For this task, the hourly rainfall estimates from the National Center for Environmental Prediction Stage IV Quantitative Precipitation Estimate were fed into the Variable Infiltration Capacity (VIC) hydrologic model and Routing Application for Parallel computation of Discharge (RAPID) routing model to estimate flow hydrographs at 69 locations for Flood2D-GPU simulation. Preliminary results of the simulation including flood inundation extents, maps of flood depths and inundation duration will be presented. Future efforts will focus on calibrating and validating the simulation results and assessing the flood damage for better understanding the impacts made by Hurricane Harvey.

A total of 2402 patients with arsenic-related skin lesions, such as hyperkeratosis, hyperpigmentation or hypopigmentation, or even skin cancer in a few villages in Southwest Guizhou Autonomous Prefecture, China represent a unique case of endemic arsenism related with indoor combustion of high arsenic coal. This study aimed to investigate the cluster of arsenism cases and the possible relevant factors including GSTP1 polymorphism in two clans of different ethnic origin living in one village for generations. Arsenism morbidity in Miao clan P was significantly lower than in the neighbouring Han clan G1 (5.9 vs. 32.7%, odds ratio (OR)=0.13, 95% confidence interval (CI): 0.06-0.27, P < 0.0001). No sex differences were confirmed inside both clans. Analyses of the environmental samples indicated that Miao clan P members were exposed to higher amounts of arsenic via inhalation and food ingestion. Hair and urine samples also proved a higher arsenic body burden in ethnic Miao individuals. No corresponding differences by sex were found. Higher frequencies of combined mutant genotype G/G1578 and A/G1578 (OR=4.72, 95% CI: 2.34-9.54, P < 0.0001) and of mutant allele G1578 (OR=3.22, 95% CI: 2.00-5.18, P < 0.0001) were detected in diagnosed arsenism patients than in non-diseased individuals. The Miao individuals showed a lower percentage of combined mutant genotypes (30.6 vs. 52.7%, OR=0.40, 95% CI: 0.19-0.84, P=0.015) as well as of mutant allele G1578 (OR=0.46, 95% CI: 0.24-0.88, P=0.017) than their Han neighbours. Conclusions Genetic predisposition influences dermal arsenism toxicity. The GSTP1 A1578G (IIe105Val) status might be a susceptibility factor for arsenic-related skin lesions.

Are recent hurricane (Harvey, Irma, Maria) disasters natural?
Trenberth, K. E.; Lijing, C.; Jacobs, P.; Abraham, J. P.
2017-12-01
Yes and no! Hurricanes are certainly natural, but human-caused climate change is supersizing them, and unbridled growth is exacerbating risk of major damages. The addition of heat-trapping gases to the atmosphere has led to observed increases in upper ocean heat content (OHC). This human-caused increase in OHC supports higher sea surface temperatures (SSTs) and atmospheric moisture. These elevated temperatures and increased moisture availability fuel tropical storms, allowing them to grow larger, longer lasting, and more intense, and with widespread heavy rainfalls. Our preliminary analysis of OHC through the August of 2017 shows not only was it by far the highest on record globally, but it was also the highest on record in the Gulf of Mexico prior to hurricane Harvey occurring. The human influence on the climate is also evident in rising sea levels, which increases risks from storm surges. These climatic changes are taking place against a background of growing habitation along coasts, which further increases the risk storms pose to life and property. This combination of planning choice and climatic change illustrates the tragedy of global warming, as evidenced by Harvey in Houston, Irma in the Caribbean and Florida, and Maria in Puerto Rico. However, future damages and loss of life can be mitigated, by stopping or slowing human-caused climate change, and through proactive planning (e.g., better building codes, increased-capacity drainage systems, shelters, and evacuation plans). We discuss the climatic and planning contexts of the unnatural disasters of the 2017 Atlantic Hurricane season, including novel indices of climate-hurricane influence.

During August 25-30, 2017, Hurricane Harvey stalled over Texas and caused extreme precipitation, particularly over Houston and the surrounding area on August 26-28. This resulted in extensive flooding with over 80 fatalities and large economic costs. It was an extremely rare event: the return period of the highest observed three-day precipitation amount, 1043.4 mm 3dy-1 at Baytown, is more than 9000 years (97.5% one-sided confidence interval) and return periods exceeded 1000 yr (750 mm 3dy-1)...

Better Data Help Make Better Decisions: Disseminating Information During Hurricane Harvey
Conner, K.; Lindner, J.; Moore, M.
2017-12-01
During large scale natural disasters, like hurricane Harvey, time-critical decisions are made on a constant basis. From evacuation orders, allocation of emergency resources, or allowing people to return home, decisions are only as good as the information upon which they are based. Better real-time data lead to better decisions which ultimately leads to improved disaster response and recovery. In 2015 Harris County Flood Control District (HCFCD) in Houston, TX began upgrading their automatic flood warning system (FWS) that dates back to the 1980s. The HCFCD network consists of 154 remote stations that report precipitation intensities and stream levels in near real time. Since the upgrades were completed in 2016 the Houston area has experienced multiple 100+ rain events, the most recent being Hurricane Harvey. The FWS generated accurate, reliable, real-time data throughout the entirety of the record breaking, four-day event. This information was disseminated to state, local and federal agencies, news outlets and the public via web sites and social media. Without this quality of data, disaster management decisions could not have been made effectively, ultimately leading to greater destruction of property and loss of life.

The coastal areas have dense onshore and marine observation network and are also routinely monitored by constellation of satellites. The monitoring of ocean, land and atmosphere through a range of meteorological parameters, provides information about the land and ocean surface. Satellite data also provide information at different pressure levels that help to access the development of tropical storms and formation of hurricanes at different categories. Integration of ground, buoys, satellite and model data showing the changes in meteorological parameters during the landfall stages of hurricane Harvey will be discussed. Hurricane Harvey was one of the deadliest hurricanes at the Gulf coast which caused intense flooding from the precipitation. The various observation networks helped city administrators to evacuate the coastal areas, that minimized the loss of lives compared to the Galveston hurricane of 1900 which took 10,000 lives. Comparison of meteorological parameters derived from buoys, ground stations and satellites associated with Harvey and 2005 Katrina hurricane present some of the interesting features of the two hurricanes.

Flood Inundation Mapping and Emergency Operations during Hurricane Harvey
Fang, N. Z.; Cotter, J.; Gao, S.; Bedient, P. B.; Yung, A.; Penland, C.
2017-12-01
Hurricane Harvey struck the Gulf Coast as Category 4 on August 25, 2017 with devastating and life-threatening floods in Texas. Harris County received up to 49 inches of rainfall over a 5-day period and experienced flooding level and impacts beyond any previous storm in Houston's history. The depth-duration-frequency analysis reveals that the areal average rainfall for Brays Bayou surpasses the 500-year rainfall in both 24 and 48 hours. To cope with this unprecedented event, the researchers at the University of Texas at Arlington and Rice University worked closely with the U.S. Army Corps of Engineers (USACE), the National Weather Service (NWS), the Texas Division of Emergency Management (TDEM), Walter P. Moore and Associates, Inc. and Halff Associates, to conduct a series of meteorological, hydrologic and hydraulic analyses to delineate flood inundation maps. Up to eight major watersheds in Harris County were delineated based the available QPE data from WGRFC. The inundation map over Brays Bayou with their impacts from Hurricane Harvey was delineated in comparison with those of 100-, 500-year, and Probable Maximum Precipitation (PMP) design storms. This presentation will provide insights for both engineers and planners to re-evaluate the existing flood infrastructure and policy, which will help build Houston stronger for future extreme storms. The collaborative effort among the federal, academic, and private entities clearly demonstrates an effective approach for flood inundation mapping initiatives for the nation.

Using integrated modeling for generating watershed-scale dynamic flood maps for Hurricane Harvey
Saksena, S.; Dey, S.; Merwade, V.; Singhofen, P. J.
2017-12-01
Hurricane Harvey, which was categorized as a 1000-year return period event, produced unprecedented rainfall and flooding in Houston. Although the expected rainfall was forecasted much before the event, there was no way to identify which regions were at higher risk of flooding, the magnitude of flooding, and when the impacts of rainfall would be highest. The inability to predict the location, duration, and depth of flooding created uncertainty over evacuation planning and preparation. This catastrophic event highlighted that the conventional approach to managing flood risk using 100-year static flood inundation maps is inadequate because of its inability to predict flood duration and extents for 500-year or 1000-year return period events in real-time. The purpose of this study is to create models that can dynamically predict the impacts of rainfall and subsequent flooding, so that necessary evacuation and rescue efforts can be planned in advance. This study uses a 2D integrated surface water-groundwater model called ICPR (Interconnected Channel and Pond Routing) to simulate both the hydrology and hydrodynamics for Hurricane Harvey. The methodology involves using the NHD stream network to create a 2D model that incorporates rainfall, land use, vadose zone properties and topography to estimate streamflow and generate dynamic flood depths and extents. The results show that dynamic flood mapping captures the flood hydrodynamics more accurately and is able to predict the magnitude, extent and time of occurrence for extreme events such as Hurricane Harvey. Therefore, integrated modeling has the potential to identify regions that are more susceptible to flooding, which is especially useful for large-scale planning and allocation of resources for protection against future flood risk.

Building Change Detection from Harvey using Unmanned Aerial System (UAS)
Chang, A.; Yeom, J.; Jung, J.; Choi, I.
2017-12-01
Unmanned Aerial System (UAS) is getting to be the most important technique in recent days since the fine spatial and high temporal resolution data previously unobtainable from traditional remote sensing platforms. Advanced UAS data can provide a great opportunity for disaster monitoring. Especially, building change detection is the one of the most important topics for damage assessment and recovery from disasters. This study is proposing a method to monitor building change with UAS data for Holiday Beach in Texas, where was directly hit by Harvey on 25 August 2017. This study adopted 3D change detection to monitor building damage and recovery levels with building height as well as natural color information. We used a rotorcraft UAS to collect RGB data twice on 9 September and 18 October 2017 after the hurricane. The UAS data was processed using Agisoft Photoscan Pro Software to generate super high resolution dataset including orthomosaic, DSM (Digital Surface Model), and 3D point cloud. We compared the processed dataset with an airborne image considerable as before-hurricane data, which was acquired on January 2016. Building damage and recovery levels were determined by height and color change. The result will show that UAS data is useful to assess building damage and recovery for affected area by the natural disaster such as Harvey.

Pebax®1657/Graphene oxide composite membranes for improved water vapor separation
Akhtar, Faheem Hassan; Kumar, Mahendra; Peinemann, Klaus-Viktor
2016-01-01
In this study composite mixed matrix membranes containing hydrophilic microphase-separated block copolymer (Pebax® 1657) and graphene oxide nanosheets were prepared using a dip coating method. Water vapor and N2 gas permeation were measured as a function of different parameters: (i) layer thickness, (ii) content of graphene oxide (GO), and (iii) content of reduced GO. Surprisingly, a concentration of only 2 wt% of GO nanosheets well dispersed in the Pebax layer boosted the selectivity 8 times by decreasing the water vapor permeance by only 12% whereas N2 gas permeance decreased by 70%. Using reduced GO instead, the water vapor permeance declined by up to 16% with no influence on the N2 gas permeance. We correlated the permeation properties of the mixed matrix membranes with different models and found, that both the modified Nielsen model and the Cussler model give good correlation with experimental findings.

The Global Flood Partnership (GFP; https://gfp.jrc.ec.europa.eu) is a multi-disciplinary group of scientists, operational agencies and flood risk managers focused on developing efficient and effective global flood management tools. Launched in 2014, its aim is to establish a partnership for global flood forecasting, monitoring and impact assessment to strengthen preparedness and response and to reduce global disaster losses. International organizations, the private sector, national authorities, universities and research agencies contribute to the GFP on a voluntary basis and benefit from a global network focused on flood risk reduction. At the onset of Hurricane Harvey, GFP was `activated' using email requests via its mailing service. Soon after, flood inundation maps, based on remote sensing analysis and modeling, were shared by different agencies, institutions, and individuals. These products were disseminated, to varying degrees of effectiveness, to federal, state and local agencies via emails and data-sharing services. This generated a broad data-sharing network which was utilized at the early stages of Hurricane Irma's impact, just two weeks after Harvey. In this presentation, we will describe the extent and chronology of the GFP response to both Hurricanes Harvey, Irma and Maria. We will assess the potential usefulness of this effort for event managers in various types of organizations and discuss future improvements to be implemented.

Brief communication: Loss of life due to Hurricane Harvey
Jonkman, Sebastiaan N.; Godfroy, Maartje; Sebastian, Antonia; Kolen, Bas
2018-04-01
An analysis was made of the loss of life caused by Hurricane Harvey. Information was collected for 70 fatalities that occurred due to the event and were recovered within the first 2 weeks after landfall. Most fatalities occurred due to drowning (81 %), particularly in and around vehicles. Males (70 %) and people over 50 years old (56 %) were overrepresented in the dataset. More than half of the fatalities occurred in the greater Houston area (n = 37), where heavy rainfall and dam releases caused unprecedented urban flooding. The majority of fatalities were recovered outside the designated 100- and 500-year flood hazard areas.

How Investment in #GovTech Tools Helped with USGS Disaster Response During Hurricane Harvey
Shah, S.; Pearson, D. K.
2017-12-01
Hurricane Harvey was an unprecedented storm event that not only included a challenge to decision-makers, but also the scientific community to provide clear and rapid dissemination of changing streamflow conditions and potential flooding concerns. Of primary importance to the U.S. Geological Survey (USGS) Texas Water Science Center was to focus on the availability of accessible data and scientific communication of rapidly changing water conditions across Texas with regards to heavy rainfall rates, rising rivers, streams, and lake elevations where USGS has monitoring stations. Infrastructure modernization leading to advanced GovTech practices and data visualization was key to the USGS role in providing data during Hurricane Harvey. In the last two years, USGS has released two web applications, "Texas Water Dashboard" and "Water-On-The-Go", which were heavily utilized by partners, local media, and municipal government officials. These tools provided the backbone for data distribution through both desktop and mobile applications as decision support during flood events. The combination of Texas Water Science Center web tools and the USGS National Water Information System handled more than 5-million data requests over the course of the storm. On the ground local information near Buffalo Bayou and Addicks/Barker Dams, as well as statewide support of USGS real-time scientific data, were delivered to the National Weather Service, U.S. Army Corps of Engineers, FEMA, Harris County Flood Control District, the general public, and others. This presentation will provide an overview of GovTech solutions used during Hurricane Harvey, including the history of USGS tool development, discussion on the public response, and future applications for helping provide scientific communications to the public.

Geotechnical Impacts of Hurricane Harvey Along the Texas, USA Coast
Smallegan, S. M.; Stark, N.; Jafari, N.; Ravichandran, N.; Shafii, I.; Bassal, P.; Figlus, J.
2017-12-01
As part of the NSF-funded Geotechnical Extreme Events Reconnaissance (GEER) Association response to Hurricane Harvey, a team of engineers and scientists mobilized to the coastal cities of Texas, USA from 1 to 5 September 2017. Damage to coastal and riverine structures due to erosion by storm surge, waves, and coastal and riverine flooding was assessed in a wide coastal zone between Corpus Christi and Galveston. Making initial landfall near Rockport, Texas on 26 August 2017, Hurricane Harvey was classified as a category 4 hurricane on the Saffir-Simpson scale with wind speeds exceeding 130 mph and an atmospheric pressure of 938 mbar. The storm stalled over the Houston area, pouring 40 inches of rain on an area encompassing more than 3,000 square miles. Hurricane Harvey, which remained a named storm for 117 hours after initial landfall, slowly moved east into the Gulf of Mexico and made final landfall near Cameron, Louisiana on 30 August. The GEER team surveyed sixteen main sites, extending from Mustang Island in the southwest to Galveston in the northeast and as far inland as Rosenburg. In Port Aransas, beach erosion and undercutting along a beach access road near Aransas Pass were observed. Due to several tide gauge failures in this area, the nearest NOAA tide gauge (#8775870 near Corpus Christi) was used to estimate water levels of 1.35 m, approximately 1.0 m above the predicted tide. In Holiday Beach, anchored retaining walls were inundated, causing backside scour along the entire length and exposing the sheetpile wall anchors. Along the Colorado River at the Highway 35 bridge near Bay City, active riverbank failure was observed and a sheet pile wall was found collapsed. Significant sediment deposits lined the vegetated riverbanks. A USGS stream gage recorded gage heights greater than 45 ft, exceeding the flood stage of 44 ft. Fronting a rubblemound seawall in Surfside Beach, a runnel and ridge formation was observed. Nearby at San Luis Pass, infilled scour

Author of this article is among rare ones who in some of the indexed magazines emphasized of that event, and on that debated also some authors from Great Britain and USA in the respectable magazine Annals of Internal medicine. Citations in majority mentioning other two "describers" or "discoverers" of pulmonary blood circulation, Miguel de Servet (1511-1553), physician and theologian, and William Harvey (1578-1657), which in his paper "An Anatomical Exercise on the Motion of the Hearth and Blood in Animals" published in 1628 described blood circulatory system. Ibn Nafis is due to its scientific work called "Second Avicenna". Some of his papers, during centuries were translated into Latin, and some published as a reprint in Arabic language. Significance of Nafis epochal discovery is the fact that it is solely based on deductive impressions, because his description of the small circulation is not occurred by in vitro observation on corps during section. It is known that he did not pay attention to the Galen theories about blood circulation. His prophecy sentence say: "If I don't know that my work will not last up to ten thousand years after me, I would not write them" Sapient sat. Searching the newest data about all three authors: Alauddin ibn Nafis (1210-1288), Michael Servetus (1511-1533) and William Harvey (1628) in the prestige Wikipedia I manage to link several most relevant facts, based on which we can in more details explain to whom from these three authors the glory and the right to call them self first describer of the pulmonary and cardiac circulation belongs. About Servetus and Harvey there is much more data than on ibn Nafis, about which on Google there are mainly references in Arabic and Turkish language, and my four references on Bosnian, with the abstracts in English. Probably the language barrier was one of the key reasons that we know so little about Nafis and so little is written, although

The record-breaking rainfall produced over the Houston region by Hurricane Harvey resulted in catastrophic and unprecedented impacts on the region's infrastructure. Notably, Houston's transportation network was crippled, with almost every major highway flooded during the five-day event. Entire neighborhoods and subdivisions were inundated, rendering them completely inaccessible to rescue crews and emergency services. Harvey has tragically highlighted the vulnerability of major thoroughfares, as well as neighborhood roads, to severe inundation during extreme precipitation events. Furthermore, it has emphasized the need for detailed accessibility characterization of road networks under extreme event scenarios in order to determine which areas of the city are most vulnerable. This analysis assesses and tracks the accessibility of Houston's major highways during Harvey's evolution by utilizing road flood/closure data from the Texas DOT. In the absence of flooded/closure data for local roads, a hybrid approach is adopted that utilizes a physics-based hydrologic model to produce high-resolution inundation estimates for selected urban watersheds in the Houston area. In particular, hydrologic output in the form of inundation depths is used to estimate the operability of local roads. Ultimately, integration of hydrologic-based estimation of road conditions with observed data from DOT supports a network accessibility analysis of selected urban neighborhoods. This accessibility analysis can identify operable routes for emergency response (rescue crews, medical services, etc.) during the storm event.

In this paper it is maintained that Raymond Williams's writings on culture are of great importance to current developments in cultural geography. His work is periodised into three stages and its different subject matters identified. An interpretation of Williams's theory of culture is offered which places particular emphasis on his concepts of 'structure of feeling' and 'knowable community'. The creative tension between Williams's holistic treatment of culture and his stress on cultural strug...

William Butler Yeats’s ‘The Symbolic System’ of William Blake
Directory of Open Access Journals (Sweden)
Arianna Antonielli
2008-03-01
Full Text Available The theosophical systems formulated by great poets, such as William Blake and William Butler Yeats, represent a personal idiosyncratic actualization of an ancient repertoire of magical symbols and occult visions. This study wants to focus the attention on the philosophical, mythical, and esoteric syncretism that W. B. Yeats drew from William Blake’s symbolical system. A fundamental step of Yeats’s deep investigation into the Blakean ‘vision’ was given by his monumental work, written together with Edwin John Ellis, on Blake’s poetic and pictorial production, completed in 1893 with a three-volume edition entitled The Works of William Blake, Poetic, Symbolic, and Critical. This work, published in London by Bernard Quaritch, deeply influenced Yeats’s symbolical and imaginary system, determining its subsequent development up to its codification in the volume of A Vision. With WWB, Yeats was able to systematize for the first time his own thought, giving unity to his Weltanschauung and his poetry. Following this hypothesis, I concentrated on Yeats’s and Ellis’s numerous analyses dedicated to Blake’s mythological and symbolical corpus and, in particular, I examined the last chapter of the first volume of the Quaritch edition. This chapter, entitled “The Symbolic System”, constitutes an unquestionable link between Yeats the reader and scholar of Blake, and Yeats the poet and follower of Blake.

Williams syndrome is a genetic neurodevelopmental disorder characterized by an uncommon hypersociability and a mosaic of retained and compromised linguistic and cognitive abilities. Nearly all clinically diagnosed individuals with Williams syndrome lack precisely the same set of genes, with breakpoints in chromosome band 7q11.23 (refs 1-5). The contribution of specific genes to the neuroanatomical and functional alterations, leading to behavioural pathologies in humans, remains largely unexplored. Here we investigate neural progenitor cells and cortical neurons derived from Williams syndrome and typically developing induced pluripotent stem cells. Neural progenitor cells in Williams syndrome have an increased doubling time and apoptosis compared with typically developing neural progenitor cells. Using an individual with atypical Williams syndrome, we narrowed this cellular phenotype to a single gene candidate, frizzled 9 (FZD9). At the neuronal stage, layer V/VI cortical neurons derived from Williams syndrome were characterized by longer total dendrites, increased numbers of spines and synapses, aberrant calcium oscillation and altered network connectivity. Morphometric alterations observed in neurons from Williams syndrome were validated after Golgi staining of post-mortem layer V/VI cortical neurons. This model of human induced pluripotent stem cells fills the current knowledge gap in the cellular biology of Williams syndrome and could lead to further insights into the molecular mechanism underlying the disorder and the human social brain.

Full Text Available This contribution presents reflections on the contributions of and the debate between David Harvey and Michael Hardt/Toni Negri that we feature as the opening part of the tripleC-special issue “Marx@200: Debating Capitalism & Perspectives for the Future of Radical Theory”. My reflection contextualises the debate by a discussing the origin and genesis of Marx’s concepts of alienation, formal/real subsumption, and primitive accumulation and b situating the arguments in earlier works by Harvey, Hardt and Negri. This paper points out differences as well as the strong commonalities between the works of Michael Hardt/Toni Negri and David Harvey. It discusses how the categories of universal alienation, formal/real subsumption of society under capital, original/ongoing primitive accumulation of capital are related. Harvey and Hardt/Negri show that Marx’s theory and politics are alive 200 years after his birth and will haunt capitalism as long as it exists. The paper concludes by arguing that Harvey’s concept of anti-value and the autonomous notion of self-valorisation point towards democratic, commons-based alternatives to capitalism.

Full Text Available One of the more colorful eras in American Southwestern archaelogy is reflected in The Great Southwest of the Fred Harvey Company and the Santa Fe Railway. Marta Weigle and Barbara A. Babcock, editors of the volume, have done a superb job weaving in early Southwestern archaeological activities with the role of the Fred Harvey Company and the Santa Fe Railway in bring the American Southwest to those "east of the Mississippi River". Many early Southwestern archaeologists made their way throughout the Southwest on the Santa Fe Railway while the "outposts of civilization" that the Fred Harvey Company provided in many railroad stations served as a " bit of home" to the traveler. This book describes the collaboration of both Fred Harvey and the Santa Fe Railroad tourism in the American Southwest and provides an excellent look into the Native American artists and their comumnities which were transformed on a massive scale by the Fred Harvey Company as it bought, sold, and popularized Native American art. Also part of the volume is an excellent discussion of the network of major museums that hold art collections which were purchased through the Harvey Company's Indian Department.

Record rainfall amounts were recorded during Hurricane Harvey in the Houston, Texas, area, leading to widespread flooding. We analyze observed precipitation from the Global Historical Climatology Network with a covariate-based extreme value statistical analysis, accounting for both the external influence of global warming and the internal influence of El Niño-Southern Oscillation. We find that human-induced climate change likely increased the chances of the observed precipitation accumulations during Hurricane Harvey in the most affected areas of Houston by a factor of at least 3.5. Further, precipitation accumulations in these areas were likely increased by at least 18.8% (best estimate of 37.7%), which is larger than the 6-7% associated with an attributable warming of 1°C in the Gulf of Mexico and Clausius-Clapeyron scaling. In a Granger causality sense, these statements provide lower bounds on the impact of climate change and motivate further attribution studies using dynamical climate models.

Handedness and corpus callosal morphology in Williams syndrome.
Martens, Marilee A; Wilson, Sarah J; Chen, Jian; Wood, Amanda G; Reutens, David C
2013-02-01
Williams syndrome is a neurodevelopmental genetic disorder caused by a hemizygous deletion on chromosome 7q11.23, resulting in atypical brain structure and function, including abnormal morphology of the corpus callosum. An influence of handedness on the size of the corpus callosum has been observed in studies of typical individuals, but handedness has not been taken into account in studies of callosal morphology in Williams syndrome. We hypothesized that callosal area is smaller and the size of the splenium and isthmus is reduced in individuals with Williams syndrome compared to healthy controls, and examined age, sex, and handedness effects on corpus callosal area. Structural magnetic resonance imaging scans were obtained on 25 individuals with Williams syndrome (18 right-handed, 7 left-handed) and 25 matched controls. We found that callosal thickness was significantly reduced in the splenium of Williams syndrome individuals compared to controls. We also found novel evidence that the callosal area was smaller in left-handed participants with Williams syndrome than their right-handed counterparts, with opposite findings observed in the control group. This novel finding may be associated with LIM-kinase hemizygosity, a characteristic of Williams syndrome. The findings may have significant clinical implications in future explorations of the Williams syndrome cognitive phenotype.

Attribution of extreme rainfall from Hurricane Harvey, August 2017
van Oldenborgh, Geert Jan; van der Wiel, Karin; Sebastian, Antonia; Singh, Roop; Arrighi, Julie; Otto, Friederike; Haustein, Karsten; Li, Sihan; Vecchi, Gabriel; Cullen, Heidi
2017-12-01
During August 25-30, 2017, Hurricane Harvey stalled over Texas and caused extreme precipitation, particularly over Houston and the surrounding area on August 26-28. This resulted in extensive flooding with over 80 fatalities and large economic costs. It was an extremely rare event: the return period of the highest observed three-day precipitation amount, 1043.4 mm 3dy-1 at Baytown, is more than 9000 years (97.5% one-sided confidence interval) and return periods exceeded 1000 yr (750 mm 3dy-1) over a large area in the current climate. Observations since 1880 over the region show a clear positive trend in the intensity of extreme precipitation of between 12% and 22%, roughly two times the increase of the moisture holding capacity of the atmosphere expected for 1 °C warming according to the Clausius-Clapeyron (CC) relation. This would indicate that the moisture flux was increased by both the moisture content and stronger winds or updrafts driven by the heat of condensation of the moisture. We also analysed extreme rainfall in the Houston area in three ensembles of 25 km resolution models. The first also shows 2 × CC scaling, the second 1 × CC scaling and the third did not have a realistic representation of extreme rainfall on the Gulf Coast. Extrapolating these results to the 2017 event, we conclude that global warming made the precipitation about 15% (8%-19%) more intense, or equivalently made such an event three (1.5-5) times more likely. This analysis makes clear that extreme rainfall events along the Gulf Coast are on the rise. And while fortifying Houston to fully withstand the impact of an event as extreme as Hurricane Harvey may not be economically feasible, it is critical that information regarding the increasing risk of extreme rainfall events in general should be part of the discussion about future improvements to Houston’s flood protection system.

Biogeochemical Impact of Hurricane Harvey on Texas Coastal Lagoons
Montagna, P.; Hu, X.; Walker, L.; Wetz, M.
2017-12-01
Hurricane Harvey made landfall Friday 25 August 2017 as a Category 4 hurricane, which is the strongest hurricane to hit the middle Texas coast since Carla in 1961. After the wind storm and storm surge, coastal flooding occurred due to the storm lingering over Texas for four more days, dumping as much as 50" of rain near Houston, producing 1:1000 year flood event. The Texas coast is characterized by lagoons behind barrier islands, and their ecology and biogeochemistry are strongly influenced by coastal hydrology. The ensuing inflow event replaced brackish water with fresh water that was high in inorganic an organic matter, significantly enhancing respiration of coastal blue carbon, and dissolved oxygen went to zero for a long period of time. Recovery will likely take months or nearly one year.

The 2017 Atlantic hurricane season included a series of storms that impacted the United States, and the Caribbean breaking a 12-year drought of landfalls in the mainland United States (Harvey and Irma), with additional impacts from the combination of Irma and Maria felt in the Caribbean. These storms caused widespread devastation resulting in a significant need to support federal partners in response to these destructive weather events. The NASA Earth Science Disasters Program provided support to federal partners including the Federal Emergency Management Agency (FEMA) and the National Guard Bureau (NGB) by leveraging remote sensing and other expertise through NASA Centers and partners in academia throughout the country. The NASA Earth Science Disasters Program leveraged NASA mission products from the GPM mission to monitor cyclone intensity, assist with cyclone center tracking, and quantifying precipitation. Multispectral imagery from the NASA-NOAA Suomi-NPP mission and the VIIRS Day-Night Band proved useful for monitoring power outages and recovery. Synthetic Aperture Radar (SAR) data from the Copernicus Sentinel-1 satellites operated by the European Space Agency were used to create flood inundation and damage assessment maps that were useful for damage density mapping. Using additional datasets made available through the USGS Hazards Data Distribution System and the activation of the International Charter: Space and Major Disasters, the NASA Earth Science Disasters Program created additional flood products from optical and radar remote sensing platforms, along with PI-led efforts to derive products from other international partner assets such as the COSMO-SkyMed system. Given the significant flooding impacts from Harvey in the Houston area, NASA provided airborne L-band SAR collections from the UAVSAR system which captured the daily evolution of record flooding, helping to guide response and mitigation decisions for critical infrastructure and public safety.

Hurricane Harvey Building Damage Assessment Using UAV Data
Yeom, J.; Jung, J.; Chang, A.; Choi, I.
2017-12-01
Hurricane Harvey which was extremely destructive major hurricane struck southern Texas, U.S.A on August 25, causing catastrophic flooding and storm damages. We visited Rockport suffered severe building destruction and conducted UAV (Unmanned Aerial Vehicle) surveying for building damage assessment. UAV provides very high resolution images compared with traditional remote sensing data. In addition, prompt and cost-effective damage assessment can be performed regardless of several limitations in other remote sensing platforms such as revisit interval of satellite platforms, complicated flight plan in aerial surveying, and cloud amounts. In this study, UAV flight and GPS surveying were conducted two weeks after hurricane damage to generate an orthomosaic image and a DEM (Digital Elevation Model). 3D region growing scheme has been proposed to quantitatively estimate building damages considering building debris' elevation change and spectral difference. The result showed that the proposed method can be used for high definition building damage assessment in a time- and cost-effective way.

During hurricane Harvey the greater east Texas area was affected by extensive flash flooding. Their localised nature meant they were too small for conventional large scale flood forecasting systems to capture. We are testing the use of two real time forecast products from the European Centre for Medium-range Weather Forecasts (ECMWF) in combination with local vulnerability information to provide flash flood forecasting tools at the medium range (up to 7 days ahead). Meteorological forecasts are the total precipitation extreme forecast index (EFI), a measure of how the ensemble forecast probability distribution differs from the model-climate distribution for the chosen location, time of year and forecast lead time; and the shift of tails (SOT) which complements the EFI by quantifying how extreme an event could potentially be. Both products give the likelihood of flash flood generating precipitation. For hurricane Harvey, 3-day EFI and SOT products for the period 26th - 29th August 2017 were used, generated from the twice daily, 18 km, 51 ensemble member ECMWF Integrated Forecast System. After regridding to 1 km resolution the forecasts were combined with vulnerable area data to produce a flash flood hazard risk area. The vulnerability data were floodplains (EU Joint Research Centre), road networks (Texas Department of Transport) and urban areas (Census Bureau geographic database), together reflecting the susceptibility to flash floods from the landscape. The flash flood hazard risk area forecasts were verified using a traditional approach against observed National Weather Service flash flood reports, a total of 153 reported flash floods have been detected in that period. Forecasts performed best for SOT = 5 (hit ratio = 65%, false alarm ratio = 44%) and EFI = 0.7 (hit ratio = 74%, false alarm ratio = 45%) at 72 h lead time. By including the vulnerable areas data, our verification results improved by 5-15%, demonstrating the value of vulnerability information within

When Hurricane Harvey made landfall outside Houston, Texas, the storm's wind speeds and unprecedented precipitation caused significant damage to the region's petrochemical infrastructure. Most notably, the company Arkema's Crosby facility suffered a power failure that led to explosions and incineration of six of its peroxide tanks. Chemicals released into the air from the explosions sent 15 emergency responders to the hospital with severe respiratory conditions and led to the evacuation of hundreds of surrounding households. Other petrochemical facilities faced other damages that resulted in unsafe and acute chemical releases into the air and water. What impacts did such chemical disasters have on the surrounding communities and emergency responders during Harvey's aftermath? What steps might companies have taken to prevent such chemical releases? And what chemical safety policies might have ensured that such disaster risks were mitigated? In this talk we will report on a survey of the extent of damage to Houston's oil and gas infrastructure and related chemical releases and discuss the role of federal chemical safety policy in preventing and mitigating the potential for such risks for future storms and other extreme weather and climate events. We will also discuss how these chemical disasters created acute toxics exposures on environmental justice communities already overburdened with chronic exposures from the petrochemical industry.

Ending Caleb Williams: on storytelling influencing William Godwin’s politics
Directory of Open Access Journals (Sweden)
Peterson Roberto da Silva
2017-12-01
Full Text Available William Godwin escreveu o romance gótico Things as They Are; or, the Adventures of Caleb Williams (“As Coisas como Elas São; ou, as Aventuras de Caleb Williams”, em tradução livre em 1794 para disseminar suas ideias filosóficas e políticas. Inicio o artigo revisando a literatura para demonstrar como sua teoria influenciou tanto sua decisão de escrever ficções quanto o tipo de ficção que ele escreveu, mostrando como o autor usou e inovou convenções do gênero gótico para transmitir suas ideias para um público mais amplo. Então comparo duas perspectivas divergentes na literatura quanto à maneira como suas narrativas influenciaram suas ideias políticas e filosóficas, em particular a partir de comentários acerca do significado e do impacto de mudanças de última hora ao desfecho de Caleb Williams. Argumento que essa relação ambígua entre narrativa e política na obra de Godwin é relevante para reflexões políticas contemporâneas sobre a relação entre representação e ação política, ou como narrativas sobre a condição humana e realidades políticas podem afetas as ideias, atitudes e relações sociais de seus narradores.

Williams-Beuren's Syndrome: A Case Report.
Zamani, Hassan; Babazadeh, Kazem; Fattahi, Saeid; Mokhtari-Esbuie, Farzad
2012-01-01
Williams-Beuren syndrome is a rare familial multisystem disorder occurring in 1 per 20,000 live births. It is characterized by congenital heart defects (CHD), skeletal and renal anomalies, cognitive disorder, social personality disorder and dysmorphic facies. We present a case of Williams syndrome that presented to us with heart murmur and cognitive problem. A 5-year-old girl referred to pediatric cardiologist because of heart murmurs. She had a systolic murmur (2-3/6) in right upper sternal border with radiation to right cervical region. She also had a bulge forehead. Angiography showed mild supra valvular aortic stenosis and mild multiple peripheral pulmonary stenosis. Fluorescent in situ hybridization (FISH) was performed and the result was: 46.XX, ish del (7q11.2) (ELN X1) (7q22 X2) ELN deletion compatible with Williams syndrome. Peripheral pulmonary artery stenosis is associated with Noonan syndrome, Alagille syndrome, Cutis laxa, Ehler-Danlos syndrome, and Silver-Russel syndrome. The patient had peripheral pulmonary artery stenosis, but no other signs of these syndromes were present, and also she had a supravalvular aortic stenosis which was not seen in other syndromes except Williams syndrome. Conclusion. According to primary symptoms, paraclinical and clinical finding such as dysmorphic facies, cognitive disorder and congenital heart defect, Williams syndrome was the first diagnosis. We suggest a more attention for evaluating heart murmur in childhood period, especially when the patient has abnormal facial features or mental problem.

Cognitive processes play an important role in the maintenance, and treatment of sleep difficulties, including insomnia. In 2002, a comprehensive model was proposed by Harvey. Since its inception the model has received >300 citations, and provided researchers and clinicians with a framework for understanding and treating insomnia. The aim of this review is two-fold. First, we review the current literature investigating each factor proposed in Harvey's cognitive model of insomnia. Second, we summarise the psychometric properties of key measures used to assess the model's factors and mechanisms. From these aims, we demonstrate both strengths and limitations of the current knowledge of appropriate measurements associated with the model. This review aims to stimulate and guide future research in this area; and provide an understanding of the resources available to measure, target, and resolve cognitive factors that may maintain chronic insomnia.

Impacts of a large array of offshore wind farms on precipitation during hurricane Harvey
Pan, Y.; Archer, C. L.
2017-12-01
Hurricane Harvey brought to the Texas coast possibly the heaviest rain ever recorded in U.S. history, which then caused flooding at unprecedented levels. Previous studies have shown that large arrays of offshore wind farms can extract kinetic energy from a hurricane and thus reduce the wind and storm surge. This study will quantitatively test weather the offshore turbines may also affect precipitation patterns. The Weather Research Forecast model is employed to model Harvey and the offshore wind farms are parameterized as elevated drag and turbulence kinetic energy sources. The turbines (7.8 MW Enercon-126 with rotor diameter D=127 m) are placed along the coast of Texas and Louisiana within 100 km from the shore, where the water depth is below 200 meters. Three spacing between turbines are considered (with the number of turbines in parenthesis): 7D×7D (149,936), 9D×9D (84,339), and 11D×11D (56,226). A fourth case (9D×9D) with a smaller area and thus less turbines (33,363) is added to the simulations to emphasize the impacts of offshore turbines installed specifically to protect the city of Houston, which was flooded heavily during hurricane Harvey. The model is integrated for 24 hours from 00UTC Aug 26th, 2017 to 00UTC Aug 27th, 2017. Model results indicate that the offshore wind farms have a strong impact on the distribution of 24-hour accumulated precipitation, with an obvious decrease onshore, downstream of the wind farms, and an increase in the offshore areas, upstream of or within the wind farms. A sector covering the metro-Houston area is chosen to study the sensitivity of the four different wind farm layouts. The spatial-average 24-hour accumulated precipitation is decreased by 37%, 28%, 20% and 25% respectively for the four cases. Compared with the control case with no wind turbines, increased horizontal wind divergence and lower vertical velocity are found where the precipitation is reduced onshore, whereas increased horizontal wind convergence and

Hurricane Harvey was one of the most extreme weather events in Texas history and left significant damages in the Houston and adjoining coastal areas. To understand better the relative impact to urban flooding of extreme amount and spatial extent of rainfall, unique geography, land use and storm surge, high-resolution water modeling is necessary such that natural and man-made components are fully resolved. In this presentation, we reconstruct spatiotemporal evolution of inundation during Hurricane Harvey using hyper-resolution modeling and quantitative image reanalysis. The two-dimensional urban flood model used is based on dynamic wave approximation and 10 m-resolution terrain data, and is forced by the radar-based multisensor quantitative precipitation estimates. The model domain includes Buffalo, Brays, Greens and White Oak Bayous in Houston. The model is simulated using hybrid parallel computing. To evaluate dynamic inundation mapping, we combine various qualitative crowdsourced images and video footages with LiDAR-based terrain data.

Social Cognition in Williams Syndrome: Face Tuning.
Pavlova, Marina A; Heiz, Julie; Sokolov, Alexander N; Barisnikov, Koviljka
2016-01-01
Many neurological, neurodevelopmental, neuropsychiatric, and psychosomatic disorders are characterized by impairments in visual social cognition, body language reading, and facial assessment of a social counterpart. Yet a wealth of research indicates that individuals with Williams syndrome exhibit remarkable concern for social stimuli and face fascination. Here individuals with Williams syndrome were presented with a set of Face-n-Food images composed of food ingredients and in different degree resembling a face (slightly bordering on the Giuseppe Arcimboldo style). The primary advantage of these images is that single components do not explicitly trigger face-specific processing, whereas in face images commonly used for investigating face perception (such as photographs or depictions), the mere occurrence of typical cues already implicates face presence. In a spontaneous recognition task, participants were shown a set of images in a predetermined order from the least to most resembling a face. Strikingly, individuals with Williams syndrome exhibited profound deficits in recognition of the Face-n-Food images as a face: they did not report seeing a face on the images, which typically developing controls effortlessly recognized as a face, and gave overall fewer face responses. This suggests atypical face tuning in Williams syndrome. The outcome is discussed in the light of a general pattern of social cognition in Williams syndrome and brain mechanisms underpinning face processing.

A new case of keratoconus associated with Williams-Beuren syndrome.
Viana, Melissa Machado; Frasson, Maria; Leão, Letícia Lima; Stofanko, Martin; Gonçalves-Dornelas, Higgor; Cunha, Pricila da Silva; de Aguiar, Marcos José Burle
2013-09-01
Williams-Beuren syndrome is a multisystemic genetic disorder caused by a contiguous gene deletion at 7q11.23. Keratoconus is a complex disease and it is suspected to have a genetic origin, although the specific gene responsible for keratoconus has not been identified. Although there are several ocular features in Williams-Beuren syndrome, keratoconus is not regularly described as part of this syndrome. To report a new patient with keratoconus and Williams-Beuren syndrome. This is the third case of an association between Williams-Beuren syndrome and keratoconus. The authors believe that the Williams-Beuren syndrome chromosome region can be a possible target for further investigation as the genetic basis of keratoconus.

Epistemologia pragmatyczna Michaela Williamsa (PRAGMATIST EPISTEMOLOGY BY MICHAEL WILLIAMS
Directory of Open Access Journals (Sweden)
Renata Ziemińska
2007-06-01
Full Text Available The article presents three main elements of Williams' epistemology: the concept of knowledge, the problem of skepticism and the concept of truth. Williams takes knowledge not as pure descriptive but partly normative concept (to know is to be engaged and entitled. He rejects the demonstrative conception of knowledge (knowledge is infallible and prefers the fallibilist conception of knowledge (knowledge is uncertain and fallible. Williams is good at bringing skeptical presuppositions to light: the demonstrative conception of knowledge and the conception of justification with Prior Grounding Requirement, epistemological realism and priority for internal knowledge. He rightly observes that when we change that presuppositions (skeptic's context, knowledge does exist. However, Williams-fallibilist is close to a skeptic: they both agree that our beliefs are uncertain. The difference is only whether some of our beliefs deserve to be called knowledge. The most important worries concern Williams' concept of truth (deflationary pragmatism. According to Williams truth has no nature and it is not a goal of inquiry. However, if truth is not a goal, we can hardly understand the previous discussion with skepticism and the defense of rationality.

Passive microwave remote sensing can provided a distinct perspective on flood events by virtue of wide sensor fields of view, frequent observations from multiple satellites, and sensitivity through clouds and vegetation. During Hurricanes Harvey and Irma, we used AMSR2 (Advanced Microwave Scanning Radiometer 2, JAXA) data to map flood extents starting from the first post-storm rain-free sensor passes. Our standard flood mapping algorithm (FloodScan) derives flooded fraction from 22-km microwave data (AMSR2 or NASA's GMI) in near real time and downscales it to 90-m resolution using a database built from topography, hydrology, and Global Surface Water Explorer data and normalized to microwave data footprint shapes. During Harvey and Irma we tested experimental versions of the algorithm designed to map the maximum post-storm flood extent rapidly and made a variety of map products available immediately for use in storm monitoring and response. The maps have several unique features including spanning the entire storm-affected area and providing multiple post-storm updates as flood water shifted and receded. From the daily maps we derived secondary products such as flood duration, maximum flood extent (Figure 1), and flood depth. In this presentation, we describe flood extent evolution, maximum extent, and local details as detected by the FloodScan algorithm in the wake of Harvey and Irma. We compare FloodScan results to other available flood mapping resources, note observed shortcomings, and describe improvements made in response. We also discuss how best-estimate maps could be updated in near real time by merging FloodScan products and data from other remote sensing systems and hydrological models.

Hurricane Harvey: Infrastructure Damage Assessment of Texas' Central Gulf Coast Region
Mooney, W. D.; Fovenyessy, S.; Patterson, S. F.
2017-12-01
We report a detailed ground-based damage survey for Hurricane Harvey, the first major hurricane to make landfall along the central Texas coast since the 1970 Category 3 Hurricane Celia. Harvey, a Category 4 storm, made landfall near Rockport, Texas on August 25th, 2017 at 10 PM local time. From September 2nd to 5th we visited Rockport and 22 nearby cities to assess the severity of the damage. Nearly all damage observed occurred as a direct result of the hurricane-force winds, rather than a storm surge. This observation is in contrast to the severe damage caused by both high winds and a significant storm surge, locally 3 to 5 m in height, in the 2013 Category 5 Hurricane Haiyan, that devastated the Philippines. We have adopted a damage scale and have given an average damage score for each of the areas investigated. Our damage contour map illustrates the areal variation in damage. The damage observed was widespread with a high degree of variability. Different types of damage included: (1) fallen fences and utility poles; (2) trees with branches broken or completely snapped in half; (3) business signs that were either partially or fully destroyed; (4) partially sunken or otherwise damaged boats; (5) and sheet metal sheds either completely or partially destroyed. There was also varying degrees of damage to both residential and commercial structures. Many homes had (6) roof damage, ranging from minor damage to complete destruction of the roof and second story, and (7) siding damage, where parts or whole sections of the homes siding had been removed. The area that had the lowest average damage score was Corpus Christi, and the areas that had the highest average damage score was both Fulton and Holiday Beach. There is no simple, uniform pattern of damage distribution. Rather, the damage was scattered, revealing hot spots of areas that received more damage than the surrounding area. However, when compared to the NOAA wind swath map, all of the damage was contained within

Skin findings in Williams syndrome.
Kozel, Beth A; Bayliss, Susan J; Berk, David R; Waxler, Jessica L; Knutsen, Russell H; Danback, Joshua R; Pober, Barbara R
2014-09-01
Previous examination in a small number of individuals with Williams syndrome (also referred to as Williams-Beuren syndrome) has shown subtly softer skin and reduced deposition of elastin, an elastic matrix protein important in tissue recoil. No quantitative information about skin elasticity in individuals with Williams syndrome is available; nor has there been a complete report of dermatologic findings in this population. To fill this knowledge gap, 94 patients with Williams syndrome aged 7-50 years were recruited as part of the skin and vascular elasticity (WS-SAVE) study. They underwent either a clinical dermatologic assessment by trained dermatologists (2010 WSA family meeting) or measurement of biomechanical properties of the skin with the DermaLab™ suction cup (2012 WSA family meeting). Clinical assessment confirmed that soft skin is common in this population (83%), as is premature graying of the hair (80% of those 20 years or older), while wrinkles (92%), and abnormal scarring (33%) were detected in larger than expected proportions. Biomechanical studies detected statistically significant differences in dP (the pressure required to lift the skin), dT (the time required to raise the skin through a prescribed gradient), VE (viscoelasticity), and E (Young's modulus) relative to matched controls. The RT (retraction time) also trended longer but was not significant. The biomechanical differences noted in these patients did not correlate with the presence of vascular defects also attributable to elastin insufficiency (vascular stiffness, hypertension, and arterial stenosis) suggesting the presence of tissue specific modifiers that modulate the impact of elastin insufficiency in each tissue. © 2014 Wiley Periodicals, Inc.

Rain resulting from Hurricane Harvey stated to spread into Harris County late in August 25 and continued until August 31 2017. This high intensity rainfall caused catastrophic flooding across the Greater Houston Area and south Texas. The objectives of this study are to use the USACE Gridded Surface Subsurface Hydrologic Analysis model (GSSHA) to: i) simulate the hydrology and hydraulics of Cypress Creek watershed and quantify the impact of hurricane Harvey on it; and ii) test potential mitigation measures, e.g., construction of a third surface reservoir on the flooding and hydrology of this watershed. Cypress Creek watershed area is 733 km2. Simulations were conducted using precipitation from two sources a) the Multisensory Precipitation Estimator radar products (MPE) and Multi-Radar Multi-Sensor (MRMS) system. Streamflow was downloaded from the USGS gauge at the outlet of the watershed. The models performance using both precipitation data was very reasonable. The construction of an 8 m high embankment at the south central part of the watershed resulted in over 22% reduction of the peak flow of the stream and also reduction of the depth of inundation across the east part of the watershed. These and other mitigation scenarios will be further discussed in details during the presentation.

A well-designed recovery strategy for lifeline infrastructure networks can lead to faster and more reliable restoration of essential services in the aftermath of natural catastrophes such as hurricanes or earthquakes. Urban and regional lifelines impact one another, while the recovery of urban lifelines in turn impacts regional infrastructural resilience, owing to the interdependence of lifelines across scales. Prior work by our team, often in collaboration, has led to the development of new recovery approaches based on network science and engineering, including centrality measures from network science, information theoretic metrics, and network optimization approaches. We have developed proof-of-concept demonstrations at both regional scales, such as for the Indian Railways Network and the US National Airspace System both subjected to multiple hazards, and to urban settings, such as the post-Hurricane recovery of combined power-subway system-of-systems in Boston and the New York City MTA after Hurricane Sandy. Here we make an attempt to understand how such methods may have been, or continue to be, applicable to the transportation network in Houston post-Harvey, and more broadly, how and to what extent lessons learned in urban and regional resilience may generalize across cases. We make an assessment of the state of the literature, process understanding, simulation models, data science methods, and best practices, necessary to address problems of this nature, with a particular focus on post-Harvey recovery of transportation services in Houston.

Investigating the ''social brain'' through Williams syndrome
International Nuclear Information System (INIS)
Nagamine, Masanori; Mimura, Masaru; Reiss, A.L.; Hoeft, F.
2010-01-01
Recent advances in social cognitive neuroscience have led to the concept of the ''social brain''. The social brain includes neural processes specialized for processing social information necessary for the recognition of self and others, and interpersonal relationships. Because of its unique behavioral phenotypic features which includes 'hypersociability', Williams syndrome has gained popularity among social cognitive neuroscientists. Individuals with Williams syndrome share the same genetic risk factor for cognitive-behavioral dysfunction utilizing brain imaging to elucidate endophenotype provides us with an unprecendented opportunity to study gene, brain and behavior relationships especially those related to social cognition. In this review, we provide an overview of neuroimaging studies on social cognition in Williams syndrome and discuss the neural basis of the social brain. (author)

Congenital heart defects in Williams syndrome.
Yuan, Shi-Min
2017-01-01
Yuan SM. Congenital heart defects in Williams syndrome. Turk J Pediatr 2017; 59: 225-232. Williams syndrome (WS), also known as Williams-Beuren syndrome, is a rare genetic disorder involving multiple systems including the circulatory system. However, the etiologies of the associated congenital heart defects in WS patients have not been sufficiently elucidated and represent therapeutic challenges. The typical congenital heart defects in WS were supravalvar aortic stenosis, pulmonary stenosis (both valvular and peripheral), aortic coarctation and mitral valvar prolapse. The atypical cardiovascular anomalies include tetralogy of Fallot, atrial septal defects, aortic and mitral valvular insufficiencies, bicuspid aortic valves, ventricular septal defects, total anomalous pulmonary venous return, double chambered right ventricle, Ebstein anomaly and arterial anomalies. Deletion of the elastin gene on chromosome 7q11.23 leads to deficiency or abnormal deposition of elastin during cardiovascular development, thereby leading to widespread cardiovascular abnormalities in WS. In this article, the distribution, treatment and surgical outcomes of typical and atypical cardiac defects in WS are discussed.

Recent paleoseismicity record in Prince William Sound, Alaska, USA
Kuehl, Steven A.; Miller, Eric J.; Marshall, Nicole R.; Dellapenna, Timothy M.
2017-12-01
Sedimentological and geochemical investigation of sediment cores collected in the deep (>400 m) central basin of Prince William Sound, along with geochemical fingerprinting of sediment source areas, are used to identify earthquake-generated sediment gravity flows. Prince William Sound receives sediment from two distinct sources: from offshore (primarily Copper River) through Hinchinbrook Inlet, and from sources within the Sound (primarily Columbia Glacier). These sources are found to have diagnostic elemental ratios indicative of provenance; Copper River Basin sediments were significantly higher in Sr/Pb and Cu/Pb, whereas Prince William Sound sediments were significantly higher in K/Ca and Rb/Sr. Within the past century, sediment gravity flows deposited within the deep central channel of Prince William Sound have robust geochemical (provenance) signatures that can be correlated with known moderate to large earthquakes in the region. Given the thick Holocene sequence in the Sound ( 200 m) and correspondingly high sedimentation rates (>1 cm year-1), this relationship suggests that sediments within the central basin of Prince William Sound may contain an extraordinary high-resolution record of paleoseismicity in the region.

The passing of Yale School of Medicine's 2010 Bicentennial occasions a moment of reflecting on the past, present, and future of medical education and research at Yale and beyond. Last June, a ribbon-cutting ceremony inaugurated the opening of the Cushing Center in the Cushing-Whitney Medical Library. Named after Harvey Cushing, an early 20th-century neurosurgeon and former Yale College alum, the dual education/exhibition space now houses hundreds of gross brain specimens constituting the Cushing Tumor Registry. Originally a personal collection, Cushing donated his numerous medical specimens, photographs, and other medical relics from his deathbed, relinquishing the brains to Yale only under the condition that a suitable space be erected to preserve the many specimens. Some 70 years later and after nearly being destroyed, Cushing's wish is fully realized: The once desiccated, hidden brains have been painstakingly restored and are now on view in the Cushing Center. The brains express Cushing's singular and spectral worldview as a surgeon, artist, athlete, soldier, book collector, and historian.

William Carlos Williams’ cubism: The sensory dimension
Directory of Open Access Journals (Sweden)
J-L Kruger
1995-05-01
Full Text Available In this article the cubism of the American poet William Carlos Williams is discussed as a product of sensory elements combined with techniques derived from the work of the visual artists associated with this style. Through the study o f a number of poems written in the period between 1917 and 1923 it is shown that Williams employs the cubist intersection of sensory planes in particular to create a sensory dimension that not only renews the traditions and mode of poetry, but also reveals the cubist concern with the defamiliarization and foregrounding of fragments of everyday experiences. Ultimately the article is an attempt to indicate Williams’ incorporation o f a sensual dimension in creating a style that achieves modernist presentation revealing an independence from both traditional literary and visual styles.

Infantile ictal apneas in a child with williams-beuren syndrome.
Myers, Kenneth A; McLeod, D Ross; Bello-Espinosa, Luis
2013-02-01
Williams-Beuren syndrome is a genetic disorder rarely associated with seizures. The few described cases of Williams-Beuren syndrome and epilepsy have primarily involved infantile spasms and deletions extending beyond the common deletion region for this disorder. We present the case of a 5-week-old child with ictal apneas and typical Williams-Beuren syndrome deletion. Diagnosis was challenging, because the child had cardiac, respiratory, and gastrointestinal abnormalities typically associated with Williams-Beuren syndrome, which are also associated with cyanotic episodes. The results of interictal electroencephalography were normal, illustrating that prolonged electroencephalography is often essential in evaluation of suspected ictal apneas. Seizure freedom was achieved with carbamazepine. Sudden death is seen in Williams-Beuren syndrome, and this case raises the question whether some of these cases may be related to ictal apneas and could potentially be preventable with appropriate pharmaceutical intervention.

The unprecedented destructive hurricane Harvey struck eastern Texas from August 25th to 29th, 2017. As the hurricane moved through the region, it dropped the equivalent of one year of precipitation within a five-day period, with peak accumulations near 165 cm. Rainfall intensity and distribution varied across the region but Harris County and portions of the lower Brazos River Basin experienced devastating flooding due to high run-off and water accumulation in the built-up area. In this study, we use a multidisciplinary approach to quantify the dynamics of carbon and water flux at different spatiotemporal resolution across land types both in and outside of the path of hurricane Harvey using a combination of remote sensing and fixed monitoring platforms of the Texas Water Observatory (TWO). We used LANDSAT imagery to compute Soil Adjusted Vegetation Index, Enhanced Vegetation Index, and Normalized Difference Moisture Index. MODIS ET, GPP, and sap flow data were used in combination with eddy covariance and meteorological data from seven sites of the TWO representative of biomes ranging from low tidal salt marsh of the Gulf Coastal Plain, Shrubland, Improved Pasture, Mixed and Native Prairies, and Crop sites. We hypothesize alteration in ecohydrological characteristics across land types, which were in the path of hurricane due to changes in vegetation structure. Specifically we used trend analysis to detect structural changes in temporal dynamics of sap flow, ET, and carbon to pulse response. In addition, we monitored trace metal concentration of soil and water pores before and immediately after the hurricane in order to predict the potential of any of the toxic metal (loid)s being mobilized in the natural water resources as a function of the changes in the redox gradient. Preliminary results indicated that tree water use was reduced on average 30% below normal days. Porewater concentration of some of the metal (loid) concentration increased (Fe, Mn, Co, As, Sb, Pb

Northern gas: Williams petrochemical feasibility study
Energy Technology Data Exchange (ETDEWEB)
Chappell, D. [Williams Energy Canada, Calgary, AB (Canada)
2002-07-01
Williams Energy is a company that is involved in the following fields: gas pipelines, exploration and production, midstream, refining, petrochemical, power, and marketing and trading. The author provides an overview of the global and Canadian infrastructure before proceeding to discuss Arctic gas, which is viewed by Williams Energy as necessary. It favors the Alaska Highway route with a consortium for project development. Williams performed a petrochemical study to determine the feasibility of a petrochemical complex utilizing natural gas liquid from an Arctic gas pipeline. The scope of the study encompassed facilities (extraction plant, cracker, polyolefins plant), size (world scale, approximately 2 billion pounds per year), and location (Fairbanks or Alberta). The study led to the following findings: (1) review of several scenarios for both locations, (2) complex to produce two grades of polyethylene, (3) feedstock cost favors Alaska, (4) construction costs lower in Alberta, (5) and the primary market for the Alaska complex would be northeast Asia, while the primary market for the Alberta location would be the United States. It was determined that both options would be viable, however Alberta was favored due to the polyethylene forecast. The challenges still being faced by Williams include low frac spread, market inefficiencies, empress volumes, carbon dioxide, and fuel and electricity cost. Each of these challenges is discussed separately. The author concludes by indicating that incremental ethane is available, carbon dioxide issues need resolution, and Alberta and Alaska are attractive for Arctic ethane petrochemical production. figs.

Celiac disease in patients with Williams-Beuren syndrome.
Mıhçı, Ercan; Nur, Banu Güzel; Berker-Karaüzüm, Sibel; Yılmaz, Aygen; Artan, Reha
2015-01-01
Celiac disease is an autoimmune, gastrointestinal disorder characterized by intolerance to the dietary grain protein gluten. An increased prevalence of celiac disease has been reported in Down syndrome and Turner syndrome, but there has been only few previous reports with respect to the association of celiac disease in Williams-Beuren syndrome. The aim of this study was to evaluate the frequency of celiac disease in our 24 Williams-Beuren syndrome patients. Gastrointestinal problems and celiac disease symptoms of patients were noted. All patients were analyzed by the titer of tissue transglutaminases IgA and IgG. HLA genotyping and intestinal biopsy was performed to the patients with positive serology. We also performed gluten free diet in the presence of compatible symptoms, serology, HLA genotyping and intestinal biopsy. In our study, two patients had positive tTG antibodies, but only one had positive biopsy finding for celiac disease. The frequency of celiac disease in patients with Williams-Beuren syndrome was estimated as 1/24 (4.1%). Though the number of participants in this study was limited, the results show that the frequency of celiac disease is higher in Williams-Beuren syndrome compared to the general population. We suggest that a high suspicion and testing for celiac disease should be recommended at certain intervals in all cases with Williams-Beuren syndrome to detect the cause of growth retardation and gastrointestinal problems.

Williams Syndrome and 15q Duplication: Coincidence versus Association.
Khokhar, Aditi; Agarwal, Swashti; Perez-Colon, Sheila
2017-01-01
Williams syndrome is a multisystem disorder caused by contiguous gene deletion in 7q11.23, commonly associated with distinctive facial features, supravalvular aortic stenosis, short stature, idiopathic hypercalcemia, developmental delay, joint laxity, and a friendly personality. The clinical features of 15q11q13 duplication syndrome include autism, mental retardation, ataxia, seizures, developmental delay, and behavioral problems. We report a rare case of a girl with genetically confirmed Williams syndrome and coexisting 15q duplication syndrome. The patient underwent treatment for central precocious puberty and later presented with primary amenorrhea. The karyotype revealed 47,XX,+mar. FISH analysis for the marker chromosome showed partial trisomy/tetrasomy for proximal chromosome 15q (15p13q13). FISH using an ELN -specific probe demonstrated a deletion in the Williams syndrome critical region in 7q11.23. To our knowledge, a coexistence of Williams syndrome and 15q duplication syndrome has not been reported in the literature. Our patient had early pubertal development, which has been described in some patients with Williams syndrome. However, years later after discontinuing gonadotropin-releasing hormone analogue treatment, she developed primary amenorrhea.

2013-01-01
Individuals with Williams syndrome (WS) present with impaired functioning of the dorsal visual stream relative to the ventral visual stream. As such, little attention has been given to ventral stream functions in WS. We investigated colour processing, a predominantly ventral stream function, for the first time in nineteen individuals with Williams syndrome. Colour discrimination was assessed using the Farnsworth-Munsell 100 hue test. Colour categorisation was assessed using a match-to-sample ...

Global and local music perception in children with Williams syndrome.
Deruelle, Christine; Schön, Daniele; Rondan, Cécilie; Mancini, Josette
2005-04-25
Musical processing can be decomposed into the appreciation of global and local elements. This global/local dissociation was investigated with the processing of contour-violated and interval-violated melodies. Performance of a group of 16 children with Williams syndrome and a group of 16 control children were compared in a same-different task. Control participants were more accurate in detecting differences in the contour-violated than in the interval-violated condition while Williams syndrome individuals performed equally well in both conditions. This finding suggests that global precedence may occur at an early perceptual stage in normally developing children. In contrast, no such global precedence is observed in the Williams syndrome population. These data are discussed in the context of atypical cognitive profiles of individuals with Williams syndrome.

Intracranial arteries in individuals with the elastin gene hemideletion of Williams syndrome.
Wint, D P; Butman, J A; Masdeu, J C; Meyer-Lindenberg, A; Mervis, C B; Sarpal, D; Morris, C A; Berman, K F
2014-01-01
Williams syndrome, a rare genetic disorder with a striking neurobehavioral profile characterized by extreme sociability and impaired visuospatial construction abilities, is caused by a hemideletion that includes the elastin gene, resulting in frequent supravavular aortic stenosis and other stenotic arterial lesions. Strokes have been reported in Williams syndrome. Although the extracranial carotid artery has been studied in a sample of patients with Williams syndrome, proximal intracranial arteries have not. Using MRA, we studied the intracranial vessels in 27 participants: 14 patients with Williams syndrome (age range, 18-44 years; mean age, 27.3 ± 9.1; 43% women) and 13 healthy control participants with similar age and sex distribution (age range, 22-52 years; mean age, 33.4 ± 7.6; 46% women). All participants with Williams syndrome had hemideletions of the elastin gene. Blinded to group allocation or to any other clinical data, a neuroradiologist determined the presence of intracranial vascular changes in the 2 groups. The Williams syndrome group and the healthy control group had similar patency of the proximal intracranial arteries, including the internal carotid and vertebral arteries; basilar artery; and stem and proximal branches of the anterior cerebral artery, MCA, and posterior cerebral arteries. The postcommunicating segment of the anterior cerebral artery was longer in the Williams syndrome group. Despite the elastin haploinsufficiency, the proximal intracranial arteries in Williams syndrome preserve normal patency.

2017-01-01
Williams syndrome is a developmental disorder including dysmorphia, cardiovascular malformations and a specific neuropsychological profile together with other associated disorders. We report the case of a 17-year old girl, born of a non-inbred marriage, with Williams syndrome discovered during an assessment of degree of failure to thrive. Its association with primary adrenal insufficiency makes it unique. Diagnosis is confirmed by cytogenetic and molecular analysis. Its management consists of the implementation of treatment for adrenal insufficiency associated with a clinico-biological monitoring.

White matter integrity deficits in prefrontal-amygdala pathways in Williams syndrome.
Avery, Suzanne N; Thornton-Wells, Tricia A; Anderson, Adam W; Blackford, Jennifer Urbano
2012-01-16
Williams syndrome is a neurodevelopmental disorder associated with significant non-social fears. Consistent with this elevated non-social fear, individuals with Williams syndrome have an abnormally elevated amygdala response when viewing threatening non-social stimuli. In typically-developing individuals, amygdala activity is inhibited through dense, reciprocal white matter connections with the prefrontal cortex. Neuroimaging studies suggest a functional uncoupling of normal prefrontal-amygdala inhibition in individuals with Williams syndrome, which might underlie both the extreme amygdala activity and non-social fears. This functional uncoupling might be caused by structural deficits in underlying white matter pathways; however, prefrontal-amygdala white matter deficits have yet to be explored in Williams syndrome. We used diffusion tensor imaging to investigate prefrontal-amygdala white matter integrity differences in individuals with Williams syndrome and typically-developing controls with high levels of non-social fear. White matter pathways between the amygdala and several prefrontal regions were isolated using probabilistic tractography. Within each pathway, we tested for between-group differences in three measures of white matter integrity: fractional anisotropy (FA), radial diffusivity (RD), and parallel diffusivity (λ(1)). Individuals with Williams syndrome had lower FA, compared to controls, in several of the prefrontal-amygdala pathways investigated, indicating a reduction in white matter integrity. Lower FA in Williams syndrome was explained by significantly higher RD, with no differences in λ(1), suggestive of lower fiber density or axon myelination in prefrontal-amygdala pathways. These results suggest that deficits in the structural integrity of prefrontal-amygdala white matter pathways might underlie the increased amygdala activity and extreme non-social fears observed in Williams syndrome.

Prieto, Ruth; Pascual, José M
2017-10-01
Norman McOmish Dott (1897-1973) developed surgical neurology in Edinburgh, Scotland, and was a scholar of worldwide renown. One of Dott's most notable contributions to neurosurgery was his understanding of hypothalamic physiology, mostly acquired through the comprehensive study of patients with lesions involving this region of the diencephalon, particularly craniopharyngiomas (CPs). Recognition of symptoms caused by hypothalamic disturbances allowed him to predict the accurate anatomical relationships between CPs and the hypothalamus, despite the rudimentary radiological methods available during the 1930s. His sophisticated knowledge permitted Dott to perform radical removals of CPs originating within the third ventricle floor with acceptable success. Between 1934 and 1937, he operated on 4 CP cases originating in the hypothalamus, achieving a satisfactory postoperative outcome in 3 of the 4 patients. Aware of the strong attachment of hypothalamic CPs to the infundibulo-tuberal area, Dott used a double transbasal and transventricular approach to these lesions, a strategy providing an optimal view and control of the tumor boundaries. The decisive mentorship of several legendary figures of physiology and neurosurgery greatly influenced Dott's surgical evolution. The experimental pituitary gland work he performed with Sir Edward Sharpey-Schäfer at the beginning of his career stirred Dott's curiosity about the issue of hypothalamus-pituitary relationships. As a result, he decided to move to Peter Bent Brigham Hospital (Boston, Massachusetts) in 1923, to train in neurosurgery and neuropathology under the guidance of the leaders in these fields, Harvey Williams Cushing (1869-1939) and Percival Sylvester Bailey (1892-1973). They inspired the young Dott and shared with him their clinical and pathological expertise, in addition to their surgical strategies for best approaching and removing these challenging tumors. In time, Dott would come to surpass his mentors. This

La justicia social y la Utopía dialética: Discutiendo con Harvey sobre espacio público
Directory of Open Access Journals (Sweden)
Márcio Valença
2013-06-01
Full Text Available Este ensayo explora la idea de justicia social y, teniendo en cuenta el papel del espacio público, el pensamiento utópico de David Harvey sobre el futuro de las ciudades. Este conocido geógrafo Inglés, que vive en EE.UU., dedica su vida a construir una teoría del desarrollo geográfico desigual que objetiva elaborar propuestas alternativas que empiecen un proceso continuo de cambios progresistas en la búsqueda de una sociedad más justa. El artículo analiza varios de sus escritos y construcciones teóricas, incluyendo a las que se refieren a la “justicia distributiva territorial” y el “utopianismo dialéctico”, como también las versiones modificadas del “derecho a la ciudad”, de Henri Lefebvre, y de “cosmopolitismo subalterno”, de Boaventura de Souza Santos. Harvey piensa que es fundamental que toda la infraestructura física y el aparato institucional producidos por la sociedad burguesa en los últimos 500 años sean sustituidos por otros sistemas que den origen a un espacio y lugar relacional alternativo, construido a partir de una “reflexión filosófica”, una “evaluación de requerimientos prácticos y de necesidades humanas básicas” y del “fermento de los movimientos sociales”.

Dental management of patient with Williams Syndrome - A case report.
Wong, Daniel; Ramachandra, Srinivas Sulugodu; Singh, Ashish Kumar
2015-01-01
Williams syndrome is a multisystemic rare genetic disorder caused by deletion of 26-28 genes in the long arm of chromosome 7. It is characterized by developmental and physical abnormalities including congenital cardiovascular abnormalities, mental retardation, neurological features, growth deficiency, genitourinary manifestations, gastrointestinal problems, musculoskeletal problems, unique behavioral characteristics, and dental problems. Dental abnormalities include malocclusion, hypodontia, malformed teeth, taurodontism, pulp stones, increased space between teeth, enamel hypoplasia, and high prevalence of dental caries. Authors report a 17-year-old female patient with underlying Williams syndrome. Oral features and problems seen in the patient are listed. Malocclusion and screwdriver shaped teeth were noticed. Generalized widening of the periodontal ligament space with vital teeth was seen. This finding has not been reported in cases of Williams syndrome earlier. Precautions taken during dental treatment in patients with Williams syndrome are also discussed.

2017-12-01
During the 2017 hurricane season, three major hurricanes-Harvey, Irma, and Maria-devastated the Atlantic coast of the US and the Caribbean Islands. Harvey set the record for the rainiest storm in continental US history, Irma was the longest-lived powerful hurricane ever observed, and Maria was the costliest storm in Puerto Rican history. The recorded maximum precipitation totals for these storms were 65, 16, and 20 inches respectively. These events provided the Center for Hydrometeorology and Remote Sensing (CHRS) an opportunity to test its global real-time satellite precipitation observation system, iRain, for extreme storm events. The iRain system has been under development through a collaboration between CHRS at the University of California, Irvine (UCI) and UNESCO's International Hydrological Program (IHP). iRain provides near real-time high resolution (0.04°, approx. 4km) global (60°N - 60°S) satellite precipitation data estimated by the PERSIANN-Cloud Classification System (PERSIANN-CCS) algorithm developed by the scientists at CHRS. The user-interactive and web-accessible iRain system allows users to visualize and download real-time global satellite precipitation estimates and track the development and path of the current 50 largest storms globally from data generated by the PERSIANN-CCS algorithm. iRain continuously proves to be an effective tool for measuring real-time precipitation amounts of extreme storms-especially in locations that do not have extensive rain gauge or radar coverage. Such areas include large portions of the world's oceans and over continents such as Africa and Asia. CHRS also created a mobile app version of the system named "iRain UCI", available for iOS and Android devices. During these storms, real-time rainfall data generated by PERSIANN-CCS was consistently comparable to radar and rain gauge data. This presentation evaluates iRain's efficiency as a tool for extreme precipitation monitoring and provides an evaluation of the

The use of emotions in narratives in Williams syndrome.
Van Herwegen, Jo; Aznar, Ana; Tenenbaum, Harriet
2014-01-01
Although individuals with Williams syndrome are very sociable, they tend to have limited contact and friendships with peers. In typically developing children the use of positive emotions (e.g., happy) has been argued to be related to peer relationships and popularity. The current study investigated the use and development of emotion words in Williams syndrome using cross-sectional developmental trajectories and examined children's use of different types of emotion words. Nineteen children with Williams syndrome (WS) and 20 typically developing (TD) children matched for chronological age told a story from a wordless picture book. Participants with WS produced a similar number of emotion words compared to the control group and the use of emotion words did not change when plotted against chronological age or vocabulary abilities in either group. However, participants with WS produced more emotion words about sadness. Links between emotion production and friendships as well as future studies are discussed. After reading this article, readers will be able to: explain the development of positive and negative emotions in Williams syndrome and recognize that emotion production is atypical in this population.

Measuring the impostor phenomenon: a comparison of Clance's IP Scale and Harvey's I-P Scale.
Holmes, S W; Kertay, L; Adamson, L B; Holland, C L; Clance, P R
1993-02-01
Many of the discrepancies reported to date in empirical investigations of the impostor phenomenon (IP) may be due in part to (a) the use of different methods for identifying individuals suffering from this syndrome (impostors), (b) the common use of a median split procedure to classify subjects and (c) the fact that subjects in many studies were drawn from impostor-prone samples. In this study, we compared the scores of independently identified impostors and nonimpostors on two instruments designed to measure the IP: Harvey's I-P Scale and Clance's IP Scale. The results suggest that Clance's scale may be the more sensitive and reliable instrument. Cutoff score suggestions for both instruments are offered.

Using novel control groups to dissect the amygdala's role in Williams syndrome.
Thornton-Wells, Tricia A; Avery, Suzanne N; Blackford, Jennifer Urbano
2011-07-01
Williams syndrome is a neurodevelopmental disorder with an intriguing behavioral phenotype-hypersociability combined with significant non-social fears. Previous studies have demonstrated abnormalities in amygdala function in individuals with Williams syndrome compared to typically-developing controls. However, it remains unclear whether the findings are related to the atypical neurodevelopment of Williams syndrome, or are also associated with behavioral traits at the extreme end of a normal continuum. We used functional magnetic resonance imaging (fMRI) to compare amygdala blood-oxygenation-level-dependent (BOLD) responses to non-social and social images in individuals with Williams syndrome compared to either individuals with inhibited temperament (high non-social fear) or individuals with uninhibited temperament (high sociability). Individuals with Williams syndrome had larger amygdala BOLD responses when viewing the non-social fear images than the inhibited temperament control group. In contrast, when viewing both fear and neutral social images, individuals with Williams syndrome did not show smaller amygdala BOLD responses relative to the uninhibited temperament control group, but instead had amygdala responses proportionate to their sociability. These results suggest heightened amygdala response to non-social fear images is characteristic of WS, whereas, variability in amygdala response to social fear images is proportionate to, and might be explained by, levels of trait sociability.

William's syndrome, in order to more completely delineate the total spectrum of the disorder, indicates that 'infantile hypercalcemia', 'peculiar facies' and 'supravalvular aortic stenosis.' In has other many vascular anomalies, such as peripheral pulmonary arterial stenosis, coronary arterial stenosis, celiac arterial stenosis, and renal aterial stenosis. Only 32% of the patients have evidence of supravalvular aortic stenosis. And it is very rare disease entity that has been reported rarely in Korea. Recently authors experienced a case that was questioned William's syndrome with peripheral pulmonary arterial stenosis, clinically and preliminary radiologically and this case was confirmed by operation. Here we report a case of William's syndrome with peripheral pulmonary arterial stenosis and reviewed literatures

Full Text Available This essay focuses on the figure of D. Teotónio de Bragança, the Archbishop of Évora between 1578 and 1602, showing the importance of his building projects and artistic decorations, under the sign of Tridentine values. He adapted the principles of ‘restauro storico’ and the revitalization of ‘imagine sacrae’ in the Early Christian sanctuaries of his archdiocese. He promoted a new type of sacred architecture using artists formed in Rome, such as the architect and sculptor Pero Vaz Pereira. The art born in Évora in the late-16th century, under the sign of the Contra-Maniera, achieves a quality that rivals with that of the reign of King John III and the humanist André de Resende. Old cults and new iconographic themes emerge with D. Teotónio, such as SS. Manços, Jordão, Comba and other martyrs considered Évora-born. He ordered several works for Madrid, Rome and Florence to enrich the Cathedral and the Carthusian Monastery founded by him. Thus this period forms one of the most remarkable chapters in Portuguese Tridentine art and deserves to be properly analyzed.En este ensayo se aborda la figura de don Teotonio de Braganza (arzobispo de Évora entre 1578 y 1602 y su legado en los programas de decoración artística y en el modo como adaptó los principios tridentinos del restauro storico y la revitalización de las sacra imagines en lugares de culto paleocristiano de su archidiócesis. Durante su munus se desarrolló un nuevo tipo de arquitectura sacra gracias a la participación de artistas con formación romana, como era el caso del arquitecto y escultor Pero Vaz Pereira. El arte que vio la luz en Évora a finales del siglo XVI, bajo el signo de la Contramaniera, alcanzó un esplendor que rivalizaría con el del reinado de Juan III y del humanista André de Resende. Con don Teotonio emergen nuevos temas y cultos, como los de los santos Mancio, Jordán, Comba y otros mártires considerados ‘eborenses’. El arzobispo encarg

Learning by observation: insights from Williams syndrome.
Foti, Francesca; Menghini, Deny; Mandolesi, Laura; Federico, Francesca; Vicari, Stefano; Petrosini, Laura
2013-01-01
Observing another person performing a complex action accelerates the observer's acquisition of the same action and limits the time-consuming process of learning by trial and error. Observational learning makes an interesting and potentially important topic in the developmental domain, especially when disorders are considered. The implications of studies aimed at clarifying whether and how this form of learning is spared by pathology are manifold. We focused on a specific population with learning and intellectual disabilities, the individuals with Williams syndrome. The performance of twenty-eight individuals with Williams syndrome was compared with that of mental age- and gender-matched thirty-two typically developing children on tasks of learning of a visuo-motor sequence by observation or by trial and error. Regardless of the learning modality, acquiring the correct sequence involved three main phases: a detection phase, in which participants discovered the correct sequence and learned how to perform the task; an exercise phase, in which they reproduced the sequence until performance was error-free; an automatization phase, in which by repeating the error-free sequence they became accurate and speedy. Participants with Williams syndrome beneficiated of observational training (in which they observed an actor detecting the visuo-motor sequence) in the detection phase, while they performed worse than typically developing children in the exercise and automatization phases. Thus, by exploiting competencies learned by observation, individuals with Williams syndrome detected the visuo-motor sequence, putting into action the appropriate procedural strategies. Conversely, their impaired performances in the exercise phases appeared linked to impaired spatial working memory, while their deficits in automatization phases to deficits in processes increasing efficiency and speed of the response. Overall, observational experience was advantageous for acquiring competencies

This research combines satellite measurements of lightning in Hurricane Harvey with ground-based lightning measurements to get a better sense of the total lightning occurring in the hurricane, both intra-cloud (IC) and cloud-to-ground (CG), and how it relates to the intensification and weakening of the tropical system. Past studies have looked at lightning trends in hurricanes using the space based Lightning Imaging Sensor (LIS) or ground-based lightning detection networks. However, both of these methods have drawbacks. For instance, LIS was in low earth orbit, which limited lightning observations to 90 seconds for a particular point on the ground; hence, continuous lightning coverage of a hurricane was not possible. Ground-based networks can have a decreased detection efficiency, particularly for ICs, over oceans where hurricanes generally intensify. With the launch of the Geostationary Lightning Mapper (GLM) on the GOES-16 satellite, researchers can study total lightning continuously over the lifetime of a tropical cyclone. This study utilizes GLM to investigate total lightning activity in Hurricane Harvey temporally; this is augmented with spatial analysis relative to hurricane structure, similar to previous studies. Further, GLM and ground-based network data are combined using Bayesian techniques in a new manner to leverage the strengths of each detection method. This methodology 1) provides a more complete estimate of lightning activity and 2) enables the derivation of the IC:CG ratio (Z-ratio) throughout the time period of the study. In particular, details of the evolution of the Z-ratio in time and space are presented. In addition, lightning stroke spatiotemporal trends are compared to lightning flash trends. This research represents a new application of lightning data that can be used in future study of tropical cyclone intensification and weakening.

Full Text Available Williams' admiration for Brueghel's landscape is coded in structural and stylistic correspondences between the poem and the painting. Structures in the poem have effects analogous to the use of devices of color, line, foregrounding in the painting. The poem, like the painting, presents a «neutral» scene but subtly insures the reader's involvement. Further, Williams draws a visual statement so that graphic features suggest a global image isomorphic with the motif of descent. Features of the poem, such as line and clause length, syntactic construction, semantic coherence, are discussed as factors that contribute to rapid glancing and increase readability. A study of readers shows their sensitivity to graphic features including the poem's shape, and corroborates the importance of stylistic features.

Category-4 Hurricane Harvey had devastating socioeconomic impacts to Houston, with flooding far past the 100-year flood zones published by FEMA. In recent decades, frequency and intensity of coastal flooding are escalating, correlated with sea level rise (SLR). Moreover, Local land subsidence (LLS) due to groundwater and hydrocarbon extraction and natural compaction changes surface elevation and slope, potentially altering drainage patterns. GPS data show a mm broad co-cyclonic subsidence due to elastic loading from the water mass measured by GPS, which is inverted to solve for the total fluid volume of 2.73x1010 m3. We additionally investigate the joint impact of an SLR and pre-cyclonic LLS on the flooding of Houston-Galveston during Hurricane Harvey. We examine vertical land motion within North American Vertical Datum 2012 for the period 2007 until the cyclone by investigating SAR imaged acquired by ALOS and Sentinel-1A/B radar satellites combined with GPS data. We find patchy, LLS bowls resulting in sinks where floodwater can collect. We map the flooding extent by comparing amplitudes of Sentinal1-A/B pixels' backscattered radar signal from pre- and post-Harvey acquisitions and estimate 782 km2 are submerged within the area of 3478 km2 of pixels covered by Sentinel frame. Comparing with the LLS map, 89% of the flooded pixels exhibit -3 mm/yr or greater vertical motion. Flooding attributed to the storm surge is determined with high-resolution LiDAR digital elevation models (DEM) and a 0.75 m storm tide inundation model, which engulfs only 195 km2 and nearby the shorelines. We estimate future inundation hazard by combining LiDAR DEMs with our InSAR derived subsidence map, projecting LLS rates forward 100 years, and modeling projected SLR from 0.4 to 1.2 meters. Were subsidence to continue unabated, the total flooded area is 281 km2 with a 0.4 m and 394 km2 with a 1.2 m SLR. Next, we add a modest storm tide (0.752 m), which increases the flooded area to 389 - 480

[Cardiology was born with the modern medical science].
de Micheli, Alfredo
2015-01-01
Modern medical science was born in the post-Renaissance age and began to consolidate towards the middle of the XVII century thanks to physicists, physiologists and biologists, most of whom were direct or indirect pupils of Galileo. The discovery of blood circulation by Harvey is now considered the only progress in physiology at the beginning of the XVII century, comparable to the current advances seen in physical sciences. The history of this exploit could be written from view point of the progressive advance in knowledge. In his experiments, Harvey referred to the authentic not imaginary experiments, and put forward irrefutable quantitative arguments. We can therefore claim that his discovery of blood circulation was the first proper explanation of an organic process and the starting point leading to experimental physiology. So it seems justified to assert that modern medical science did not all rise suddenly, but was gradually structured starting from the middle of the XVII century following the path traced by William Harvey in light of Galileo's thought.

Emergency Response Imagery Related to Hurricanes Harvey, Irma, and Maria
Worthem, A. V.; Madore, B.; Imahori, G.; Woolard, J.; Sellars, J.; Halbach, A.; Helmricks, D.; Quarrick, J.
2017-12-01
NOAA's National Geodetic Survey (NGS) and Remote Sensing Division acquired and rapidly disseminated emergency response imagery related to the three recent hurricanes Harvey, Irma, and Maria. Aerial imagery was collected using a Trimble Digital Sensor System, a high-resolution digital camera, by means of NOAA's King Air 350ER and DeHavilland Twin Otter (DHC-6) Aircraft. The emergency response images are used to assess the before and after effects of the hurricanes' damage. The imagery aids emergency responders, such as FEMA, Coast Guard, and other state and local governments, in developing recovery strategies and efforts by prioritizing areas most affected and distributing appropriate resources. Collected imagery is also used to provide damage assessment for use in long-term recovery and rebuilding efforts. Additionally, the imagery allows for those evacuated persons to see images of their homes and neighborhoods remotely. Each of the individual images are processed through ortho-rectification and merged into a uniform mosaic image. These remotely sensed datasets are publically available, and often used by web-based map servers as well as, federal, state, and local government agencies. This poster will show the imagery collected for these three hurricanes and the processes involved in getting data quickly into the hands of those that need it most.

Rorty, Williams, and Davidson: Skepticism and Metaepistemology
Directory of Open Access Journals (Sweden)
Christopher Ranalli
2013-07-01
Full Text Available We revisit an important exchange on the problem of radical skepticism between Richard Rorty and Michael Williams. In his contribution to this exchange, Rorty defended the kind of transcendental approach to radical skepticism that is offered by Donald Davidson, in contrast to Williams’s Wittgenstein-inspired view. It is argued that the key to evaluating this debate is to understand the particular conception of the radical skeptical problem that is offered in influential work by Barry Stroud, a conception of the skeptical problem which generates metaepistemological ramifications for anti-skeptical theories. In particular, we argue that, contra Williams, Rorty’s view that Davidson was offering a theoretical diagnosis of radical skepticism can be consistently maintained with his transcendental approach.

On August 25, 2017, Hurricane Harvey made landfall between Port Aransas and Port O'Connor, Texas, bringing with it unprecedented amounts of rainfall and flooding. In times of natural disasters of this nature, emergency responders require timely and accurate information about the hazard in order to assess and plan for disaster response. Due to the extreme flooding impacts associated with Hurricane Harvey, delineations of water extent were crucial to inform resource deployment. Through the USGS's Hazards Data Distribution System, government and commercial vendors were able to acquire and distribute various satellite imagery to analysts to create value-added products that can be used by these emergency responders. Rapid-response water extent maps were created through a collaborative multi-organization and multi-sensor approach. One team of researchers created Synthetic Aperture Radar (SAR) water extent maps using modified Copernicus Sentinel data (2017), processed by ESA. This group used backscatter images, pre-processed by the Alaska Satellite Facility's Hybrid Pluggable Processing Pipeline (HyP3), to identify and apply a threshold to identify water in the image. Quality control was conducted by manually examining the image and correcting for potential errors. Another group of researchers and graduate student volunteers derived water masks from high resolution DigitalGlobe and SPOT images. Through a system of standardized image processing, quality control measures, and communication channels the team provided timely and fairly accurate water extent maps to support a larger NASA Disasters Program response. The optical imagery was processed through a combination of various band thresholds by using Normalized Difference Water Index (NDWI), Modified Normalized Water Index (MNDWI), Normalized Difference Vegetation Index (NDVI), and cloud masking.

MacWilliams Identity for M-Spotty Weight Enumerator
Suzuki, Kazuyoshi; Fujiwara, Eiji
M-spotty byte error control codes are very effective for correcting/detecting errors in semiconductor memory systems that employ recent high-density RAM chips with wide I/O data (e.g., 8, 16, or 32bits). In this case, the width of the I/O data is one byte. A spotty byte error is defined as random t-bit errors within a byte of length b bits, where 1 le t ≤ b. Then, an error is called an m-spotty byte error if at least one spotty byte error is present in a byte. M-spotty byte error control codes are characterized by the m-spotty distance, which includes the Hamming distance as a special case for t =1 or t = b. The MacWilliams identity provides the relationship between the weight distribution of a code and that of its dual code. The present paper presents the MacWilliams identity for the m-spotty weight enumerator of m-spotty byte error control codes. In addition, the present paper clarifies that the indicated identity includes the MacWilliams identity for the Hamming weight enumerator as a special case.

N-acetylcysteine for neuropsychiatric symptoms in a woman with Williams syndrome.
Pineiro, Mildred Lopez; Roberts, Antoinette M; Waxler, Jessica L; Mullett, Jennifer E; Pober, Barbara R; McDougle, Christopher J
2014-11-01
Williams syndrome is a relatively rare genetic disorder caused by the hemizygous microdeletion of a region in chromosome 7q11.23. Individuals with Williams syndrome typically present with a highly social, overfriendly, and empathic personality. Comorbid medical and neuropsychiatric disorders are common. Reports of effective pharmacological treatment of associated neuropsychiatric disorders are limited. The authors describe the successful treatment of interfering anger, aggression, and hair-pulling with N-acetylcysteine in a 19-year-old woman with Williams syndrome. The neuropsychiatric symptoms emerged 1 week following an upper gastrointestinal endoscopy, for which fentanyl, midazolam, and propofol were used as anesthetics. The patient's treatment course and hypothesized mechanisms underlying the clinical presentation and symptom resolution are described. © The Author(s) 2014.

Seasonal distribution of Dall's porpoise in Prince William Sound, Alaska
Moran, John R.; O'Dell, Matthew B.; Arimitsu, Mayumi L.; Straley, Janice M.; Dickson, Danielle M. S.
2018-01-01
Dall's porpoise, Phocoenoides dalli, are a conspicuous predator in the Prince William Sound ecosystem, yet there has been little effort directed towards monitoring this species since the 1980s, prior to the Exxon Valdez oil spill. We used vessel-based surveys to examine the seasonal distribution of Dall's porpoise in the waters of Prince William Sound during eight years from 2007 to 2015. Over the course of 168 days and 15,653 km of survey effort, 921 Dall's porpoise were encountered in 210 groups. We estimate an encounter rate of 0.061 porpoise/km traveled or 1 porpoise encountered for every 16.5 km traveled. Dall's porpoise were found throughout the year in Prince William Sound, and used a wide range of habitats, including those not considered typical of the species, such as bays, shallow water, and nearshore waters. Dall's porpoise seasonally shifted their center of distribution from the western passages in fall to the bays of the eastern Sound in winter and spring. Dall's porpoises were widely dispersed throughout the Sound in summer. We identified potential Dall's porpoise habitat (depth, slope, and distance from shore) within Prince William Sound using generalized additive models (GAM). Dall's porpoise were found in deeper water during summer and in shallowest water during spring. We propose that their use of novel habitats is a function of reduced predation risk associated with the decline of their main predator, killer whales (Orcinus orca), following the Exxon Valdez oil spill, and the presence of overwintering and spawning Pacific herring (Clupea pallasii). While the size of the Dall's porpoise population within Prince William Sound remains unknown, our encounter rates were lower than those reported in the 1970s. Their high metabolic rate and ubiquitous presence makes them one of the more important, yet understudied, forage fish predators in the region.

Attention to Faces in Williams Syndrome
Riby, Deborah M.; Jones, Nicola; Brown, Philippa H.; Robinson, Lucy J.; Langton, Stephen R. H.; Bruce, Vicki; Riby, Leigh M.
2011-01-01
Williams syndrome (WS) is associated with distinct social behaviours. One component of the WS social phenotype is atypically prolonged face fixation. This behaviour co-exists with attention difficulties. Attention is multi-faceted and may impact on gaze behaviour in several ways. Four experiments assessed (i) attention capture by faces, (ii)…

Full Text Available There are times when something is simply so familiar that we can no longer see it at all. It can be a story, or a concept, or even a flesh-and-blood person. Familiarity breeds not only contempt, but a kind of invisibility as well. For too many of us, such is the case with Sir William Osler. In his time (1849–1919, many considered him to be one of the greatest practitioners, teachers, and writers ever in the field of medicine. He was instrumental in the founding of the Medical Library Association (MLA and was elected its second president.

Optical projects in the Clinic program at Harvey Mudd College
Yang, Q.
2017-08-01
Clinic program is the senior capstone program at Harvey Mudd College (HMC). Multidisciplinary and industry-sponsored projects allow a team of students to solve a real-world problem over one academic year. Over its 50 plus years, Clinic program has completed numerous optics related projects. This report gives an overview of the Clinic program, reviews recent optical projects and discusses how this program supports the learning of the HMC engineering students. A few sample optical projects with more details are presented to provide an insight of what challenges that undergraduates can overcome. Students achieve learning within the optics discipline and the related engineering disciplines. The experiences in these optical projects indicate the great potential to bringing optical hands-on projects into the undergraduate level. Because of the general engineering curriculum at HMC, these projects often work the best with a multidisciplinary nature even if the core of the project is optically focused. Students gain leadership training, oral and written communication skills and experiences in team work. Close relationship with the sponsor liaisons allows for the students to gain skills in professional conduct, management of tight schedule and a specified budget, and it well prepares the students to their engineering practice. Optical projects have their own sets of specific challenges, so it needs to be chosen properly to match the undergraduate skill sets such as those of HMC engineering students.

Harvey Cushing Treated the First Known Patient With Carney Complex.
Tsay, Cynthia J; Stratakis, Constantine A; Faucz, Fabio Rueda; London, Edra; Stathopoulou, Chaido; Allgauer, Michael; Quezado, Martha; Dagradi, Terry; Spencer, Dennis D; Lodish, Maya

Carney complex (CNC) is a syndrome characterized by hyperplasia of endocrine organs and may present with clinical features of Cushing syndrome and acromegaly due to functional adrenal and pituitary gland tumors. CNC has been linked to mutations in the regulatory subunit of protein kinase A type I-alpha ( PRKAR1A ) gene. Tissue samples were taken from the hypothalamus or thalamus or tumors of patients with pituitary adenomas seen and operated on by neurosurgeon Harvey Cushing between 1913 and 1932. Following DNA extraction, sequencing for genes of interest was attempted, including PRKAR1A , AIP , USP8 , GNAS1 , and GPR101 , to explore the possibility that these mutations associated with acromegaly, CNC, and Cushing syndrome have been conserved over time. We report a patient described by Dr. Cushing in 1914 with a clinical presentation and postmortem findings suggestive of CNC. Genetic sequencing of the hypothalamus and pituitary adenoma revealed a germline heterozygous p.Arg74His mutation in the PRKAR1A gene, a codon previously described as mutated in CNC, but with a novel amino acid change. This patient is, to our knowledge, the first molecularly confirmed individual with CNC. This case demonstrates the power of modern genetics in studying archived tissues and the importance of recording detailed clinical notes in the diagnosis of disease.

Williams syndrome is a contiguous gene deletion syndrome resulting from a heterozygous deletion on chromosome 7q11.23, and is characterized by distinctive facial features and supravalvular aortic stenosis (SVAS). This syndrome rarely presents unpredictable cardiac death, and yet, as illustrated in the present case, it is still not possible to predict it, even on close monitoring. We herein describe the case of a 6-year-old Japanese girl with Williams syndrome, who had sudden cardiac collapse due to cardiac infarction after pharyngitis. Cardiac failure followed a critical course that did not respond to catecholamine support or heart rest with extracardiac mechanical support. Although marked coronary stenosis was not present, the left coronary cusp abnormally adhered to the aortic wall, which may synergistically cause coronary ostium occlusion with SVAS. Altered hemodynamic state, even that caused by the common cold, may lead to critical myocardial events in Williams syndrome with SVAS. © 2015 Japan Pediatric Society.

Who Invented the Word Asteroid: William Herschel or Stephen Weston?
Cunningham, Clifford J.; Orchiston, Wayne
2011-11-01
William Herschel made the first serious study of 1 Ceres and 2 Pallas in the year 1802. He was moved by their dissimilarities to the other planets to coin a new term to distinguish them. For this purpose he enlisted the aid of his good friends William Watson and Sir Joseph Banks. Watson gave him a long list of possible names, which Herschel rejected. With a lifetime of experience classifying and naming newly found objects in nature, Banks became the man both Erasmus Darwin (in 1781) and William Herschel (in 1802) turned to for sage advice in developing a new descriptive language. In the case of Ceres and Pallas, Banks turned the task over to his friend, the noted philologist Stephen Weston, FRS. It has recently been stated by a noted British historian that it was Weston - not Herschel - who coined the term 'asteroid' to collectively describe Ceres and Pallas. This claim is investigated, and parallels are drawn in the use of neologism in astronomy and botany.

The scientific legacy of William Herschel
2018-01-01
This book presents a modern scholarly analysis of issues associated with England’s most famous astronomer, William Herschel. The world’s leading experts on Herschel, discoverer of the planet Uranus, here offer their combined wisdom on many aspects of his life and astronomical research. Solar system topics include comets, Earth’s Moon, and the spurious moons of Uranus, all objects whose observation was pioneered by Herschel. The contributors examine his study of the structure of the Milky Way and an in-depth look at the development of the front view telescopes he built. The popular subject of extraterrestrial life is looked at from the point of view of both William Herschel and his son John, both of whom had an interest in the topic. William’s personal development through the educational system of the late eighteenth-century is also explored, and the wide range of verse and satire in various languages associated with his discoveries is collected here for the first time. Hershel worked at a time of i...

Holocene deposition and megathrust splay fault geometries within Prince William Sound, Alaska
Finn, S.; Liberty, L. M.; Haeussler, P. J.; Pratt, T. L.
2011-12-01
New high resolution sparker seismic reflection data, in conjunction with reprocessed legacy seismic data, provide the basis for a new fault, fold, and Holocene sediment thickness database for Prince William Sound, Alaska. Additionally, legacy airgun seismic data in Prince William Sound and the Gulf of Alaska tie features on these new sparker data to deeper portions of megathrust splay faults. We correlate regionally extensive bathymetric lineaments within Prince William Sound to megathrust splay faults, such as the ones that ruptured in the 1964 M9.2 earthquake. Lastly, we estimate Holocene sediment thickness within Prince William Sound to better constrain the Holocene fault history throughout the region. We identify three seismic facies related to Holocene, Quaternary, and Tertiary strata that are crosscut by numerous high angle normal faults in the hanging wall of the megathrust splay faults. The crustal-scale seismic reflection profiles show splay faults emerging from 20 km depth between the Yakutat block and North American crust and surfacing as the Hanning Bay and Patton Bay faults. A change in exhumation rates, slip rates, and fault orientation appears near Hinchinbrook that we attribute to differences in subducted slab geometry. Based on our slip rate analysis, we calculate average Holocene displacements of 20 m and 100 m in eastern and western Prince William Sound, respectively. Landward of two splay faults exposed on Montague Island, we observe subsidence, faulting, and landslides that record deformation associated with the 1964 and older megathrust earthquakes.

2014-01-30
Reports on twin pairs concordant and discordant for Williams syndrome were published before, but no study unravelled sleep physiology in these cases yet. We aim to fill this gap by analyzing sleep records of a twin pair discordant for Williams syndrome extending our focus on presleep wakefulness and sleep spindling. We performed multiplex ligation-dependent probe amplification of the 7q11.23 region of a 17 years old dizygotic opposite-sex twin pair discordant for Williams syndrome. Polysomnography of laboratory sleep at this age was analyzed and followed-up after 1.5 years by ambulatory polysomnography. Sleep stages scoring, EEG power spectra and sleep spindle analyses were carried out. The twin brother showed reduced levels of amplification for all of the probes in the 7q11.23 region indicating a typical deletion spanning at least 1.038 Mb between FKBP6 and CLIP2. The results of the twin sister showed normal copy numbers in the investigated region. Lower sleep times and efficiencies, as well as higher slow wave sleep percents of the twin brother were evident during both recordings. Roughly equal NREM, Stage 2 and REM sleep percents were found. EEG analyses revealed state and derivation-independent decreases in alpha power, lack of an alpha spectral peak in presleep wakefulness, as well as higher NREM sleep sigma peak frequency in the twin brother. Faster sleep spindles with lower amplitude and shorter duration characterized the records of the twin brother. Spectra show a striking reliability and correspondence between the two situations (laboratory vs. home records). Alterations in sleep and specific neural oscillations including the alpha/sigma waves are inherent aspects of Williams syndrome.

William's syndrome, in order to more completely delineate the total spectrum of the disorder, indicates that 'infantile hypercalcemia', 'peculiar facies' and 'supravalvular aortic stenosis.' In has other many vascular anomalies, such as peripheral pulmonary arterial stenosis, coronary arterial stenosis, celiac arterial stenosis, and renal aterial stenosis. Only 32% of the patients have evidence of supravalvular aortic stenosis. And it is very rare disease entity that has been reported rarely in Korea. Recently authors experienced a case that was questioned William's syndrome with peripheral pulmonary arterial stenosis, clinically and preliminary radiologically and this case was confirmed by operation. Here we report a case of William's syndrome with peripheral pulmonary arterial stenosis and reviewed literatures.

Colour discrimination and categorisation in Williams syndrome.
Farran, Emily K; Cranwell, Matthew B; Alvarez, James; Franklin, Anna
2013-10-01
Individuals with Williams syndrome (WS) present with impaired functioning of the dorsal visual stream relative to the ventral visual stream. As such, little attention has been given to ventral stream functions in WS. We investigated colour processing, a predominantly ventral stream function, for the first time in nineteen individuals with Williams syndrome. Colour discrimination was assessed using the Farnsworth-Munsell 100 hue test. Colour categorisation was assessed using a match-to-sample test and a colour naming task. A visual search task was also included as a measure of sensitivity to the size of perceptual colour difference. Results showed that individuals with WS have reduced colour discrimination relative to typically developing participants matched for chronological age; performance was commensurate with a typically developing group matched for non-verbal ability. In contrast, categorisation was typical in WS, although there was some evidence that sensitivity to the size of perceptual colour differences was reduced in this group. Copyright © 2013 Elsevier Ltd.

Lessons from the history of medicine.
Waller, John
2008-01-01
What is the point of teaching the history of medicine? Many historians and clinicians find it regrettable that some medical students today will graduate knowing almost nothing of such "greats" of the past as Hippocrates, Galen, Vesalius, Harvey, Lister, and Pasteur. But does this really matter? After all, traditional history of medicine curricula tended to distort medicine's past, omitting the countless errors, wrong turns, fads, blunders, and abuses, in order to tell the sanitized stories of a few scientific superheroes. Modern scholarship has seriously challenged most of these heroic dramas; few of our heroes were as farsighted, noble, or obviously correct as once thought. Joseph Lister, for example, turns out to have had filthy wards, whereas William Harvey was devoted to the Aristotelianism he was long said to have overthrown [1]. But as the history of medicine has become less romanticized, it has also become much more relevant, for it promises to impart useful lessons in the vital importance of scientific scepticism.

William Barlow and the Determination of Atomic Arrangement in Crystals.
Mauskopf, Seymour H
2015-04-01
William Barlow (1845-1934) was an important if unconventional scientist, known for having developed the 'closest-packing' atomic models of crystal structure. He resumed an early nineteenth-century tradition of utilizing crystallographical and chemical data to determine atomic arrangements in crystals. This essay recounts Barlow's career and scientific activity in three parts: (a) His place in the tradition of determining atomic arrangement in context of this earlier tradition and of contemporaneous developments of crystallography and chemistry, (b) his unconventional career, and (c) the 'success' of his program to determine atomic arrangements in crystals and its influence on the work of William Lawrence Bragg.

Prior to landfall of Hurricane Harvey on August 25, 2017, instrumentation was deployed on the seaward and landward sides of a barrier island on the central Texas Gulf Coast to collect in-situ hydrodynamic measurements during storm impact. High-resolution devices capable of withstanding extreme conditions included inexpensive pressure transducers and tilt current meters mounted within and atop (respectively) shallow monitoring wells. In order to link measurements of storm hydrodynamics with the morphological evolution of the barrier, pre- and post-storm digital elevation models were generated using a combination of unmanned aerial imagery, LiDAR, and real-time kinematic GPS. Push-cores were collected and analyzed for grain size and sedimentary structure to relate hydrodynamic observations with the local character of storm-generated deposits. Observations show that at Hog Island, located approximately 160 miles northeast of Harvey's landfall location, storm surge inundated an inactive storm channel. Infragravity waves (0.003 - 0.05 Hz) dominated the water motion onshore of the berm crest over a 24-hour period proximate to storm landfall. Over this time, approximately 50 cm of sediment accreted vertically atop the instrument located in the backshore. Storm deposits at this location contained sub-parallel alternating laminae of quartz and heavy mineral-enriched sand. While onshore progression of infragravity waves into the back-barrier was observed over several hours prior to storm landfall, storm deposits in the back-barrier lack the characteristic laminae preserved in the backshore. These field measurements will ultimately be used to constrain and validate numerical modeling schemes that explore morphodynamic conditions of barriers in response to extreme storms (e.g., XBeach, CSHORE). This study provides a unique data set linking extreme storm hydrodynamics with geomorphic changes during a relatively low surge, but highly dissipative wave event.

Williams syndrome (7q11.23 microdeletion) is characterized by specific alterations in neurocognitive architecture and functioning, as well as disordered sleep. Here we analyze the region, sleep state and frequency-specific EEG synchronization of whole night sleep recordings of 21 Williams syndrome and 21 typically developing age- and gender-matched subjects by calculating weighted phase lag indexes. We found broadband increases in inter- and intrahemispheric neural connectivity for both NREM and REM sleep EEG of Williams syndrome subjects. These effects consisted of increased theta, high sigma, and beta/low gamma synchronization, whereas alpha synchronization was characterized by a peculiar Williams syndrome-specific decrease during NREM states (intra- and interhemispheric centro-temporal) and REM phases of sleep (occipital intra-area synchronization). We also found a decrease in short range, occipital connectivity of NREM sleep EEG theta activity. The striking increased overall synchronization of sleep EEG in Williams syndrome subjects is consistent with the recently reported increase in synaptic and dendritic density in stem-cell based Williams syndrome models, whereas decreased alpha and occipital connectivity might reflect and underpin the altered microarchitecture of primary visual cortex and disordered visuospatial functioning of Williams syndrome subjects.

To reveal the relation between intellectual disability and the deleted intervals in Williams syndrome, we performed an array comparative genomic hybridization analysis and standardized developmental testing for 11 patients diagnosed as having Williams syndrome based on fluorescent in situ hybridization testing. One patient had a large 4.2-Mb deletion spanning distally beyond the common 1.5-Mb intervals observed in 10/11 patients. We formulated a linear equation describing the developmental age of the 10 patients with the common deletion; the developmental age of the patient with the 4.2-Mb deletion was significantly below the expectation (developmental age = 0.51 × chronological age). The large deletion may account for the severe intellectual disability; therefore, the use of array comparative genomic hybridization may provide practical information regarding individuals with Williams syndrome. © 2014 Japanese Teratology Society.

Williams-Beuren syndrome is a rare contiguous gene syndrome, characterized by intellectual disability, facial dysmorphisms, connective-tissue abnormalities, cardiac defects, structural brain abnormalities, and transient infantile hypercalcemia. Genes lying telomeric to RFC2, including CLIP2, GTF2I and GTF2IRD1, are currently thought to be the most likely major contributors to the typical Williams syndrome cognitive profile, characterized by a better-than-expected auditory rote-memory ability, a relative sparing of language capabilities, and a severe visual-spatial constructive impairment. Atypical deletions in the region have helped to establish genotype-phenotype correlations. So far, however, hardly any deletions affecting only a single gene in the disease region have been described. We present here two healthy siblings with a pure, hemizygous deletion of CLIP2. A putative role in the cognitive and behavioral abnormalities seen in Williams-Beuren patients has been suggested for this gene on the basis of observations in a knock-out mouse model. The presented siblings did not show any of the clinical features associated with the syndrome. Cognitive testing showed an average IQ for both and no indication of the Williams syndrome cognitive profile. This shows that CLIP2 haploinsufficiency by itself does not lead to the physical or cognitive characteristics of the Williams-Beuren syndrome, nor does it lead to the Williams syndrome cognitive profile. Although contribution of CLIP2 to the phenotype cannot be excluded when it is deleted in combination with other genes, our results support the hypothesis that GTF2IRD1 and GTF2I are the main genes causing the cognitive defects associated with Williams-Beuren syndrome.

Impact of GPM Rainrate Data Assimilation on Simulation of Hurricane Harvey (2017)
Li, Xuanli; Srikishen, Jayanthi; Zavodsky, Bradley; Mecikalski, John
2018-01-01
Built upon Tropical Rainfall Measuring Mission (TRMM) legacy for next-generation global observation of rain and snow. The GPM was launched in February 2014 with Dual-frequency Precipitation Radar (DPR) and GPM Microwave Imager (GMI) onboard. The GPM has a broad global coverage approximately 70deg S -70deg N with a swath of 245/125-km for the Ka (35.5 GHz)/Ku (13.6 GHz) band radar, and 850-km for the 13-channel GMI. GPM also features better retrievals for heavy, moderate, and light rain and snowfall To develop methodology to assimilate GPM surface precipitation data with Grid-point Statistical Interpolation (GSI) data assimilation system and WRF ARW model To investigate the potential and the value of utilizing GPM observation into NWP for operational environment The GPM rain rate data has been successfully assimilated using the GSI rain data assimilation package. Impacts of rain rate data have been found in temperature and moisture fields of initial conditions. 2.Assimilation of either GPM IMERG or GPROF rain product produces significant improvement in precipitation amount and structure for Hurricane Harvey (2017) forecast. Since IMERG data is available half-hourly, further forecast improvement is expected with continuous assimilation of IMERG data

Full Text Available British author Helen Maria Williams (1759-1827 was a well-known figure in the eighteenth century literary circles, whose work was praised by Elizabeth Montagu, Samuel Johnson, Dorothy and William Wordsworth, Mary Wollstonecraft, Hester Piozzi or Alexander von Humboldt. In her early poems Edwin and Eltruda (1782, An Ode to the Peace (1783 and Peru (1784, Williams starts to reveal her political tendencies by appealing to strong empathic feelings as a key to social and political transformation. As a result of her interest in politics, she travelled to France in 1790 and published her most acclaimed work Letters from France (1790. However, the rest of her production has received little critical attention by modern scholars, who have overlooked her involvement in translation. Williams’ only extant novel, Julia (1790 is in fact a creative translation of Rousseau’s Julie ou La Nouvelle Héloïse (1761, in which Williams includes poems that evidence her interest in revolutionary politics. Four years later, she translated Bernardin de Saint Pierre’s Paul et Virginie, while she was imprisoned in Paris. While translating novels was regarded as a respectable exercise for women writers, Williams challenges gender assumptions by translating Researches (1814 and the seven volumes of Personal Narrative (1814-1829, which had been produced by one of the most influential eighteenth century scientists, Alexander von Humboldt. This article interrogates how Williams makes use of translation to access areas of knowledge traditionally restricted to men, such as philosophy, politics and science. For this purpose, I will focus on her translations of the work of two leading intellectual figures of the eighteenth century, Rousseau and Von Humboldt.

William and Caroline Herschel pioneers in late 18th-century astronomy
Hoskin, Michael
2013-01-01
This beautifully structured book presents the essentials of William and Caroline Herschel's pioneering achievements in late 18th-century astronomy. Michael Hoskin shows that William Herschel was the first observational cosmologist and one of the first observers to attack the sidereal universe beyond the solar system:Herschel built instruments far better than any being used at the royal observatory. Aided by his sister Caroline, he commenced a great systematic survey that led to his discovery of Uranus in 1781.Unlike observers before him, whose telescopes did not reveal them as astronomical obj

We describe and evaluate an integrative hypothesis for helping to explain the major neurocognitive features of individuals with Williams syndrome region deletions and duplications. First, we demonstrate how the cognitive differences between Williams syndrome individuals, individuals with duplications of this region, and healthy individuals parallel the differences between individuals subject to effects of increased or decreased oxytocin. Second, we synthesize evidence showing that variation in expression of the gene GTF2I (General Transcription Factor II-I) underlies the primary social phenotypes of Williams syndrome and that common genetic variation in GTF2I mediates oxytocin reactivity, and its correlates, in healthy populations. Third, we describe findings relevant to the hypothesis that the GTF2I gene is subject to parent of origin effects whose behavioral expression fits with predictions from the kinship theory of genomic imprinting. Fourth, we describe how Williams syndrome can be considered, in part, as an autistic syndrome of Lorna Wing's 'active-but-odd' autism subtype, in contrast to associations of duplications with both schizophrenia and autism.

Williams syndrome and mature B-Leukemia: A random association?
Decimi, Valentina; Fazio, Grazia; Dell'Acqua, Fabiola; Maitz, Silvia; Galbiati, Marta; Rizzari, Carmelo; Biondi, Andrea; Cazzaniga, Giovanni; Selicorni, Angelo

Williams syndrome (WBS) is a rare neurodevelopmental disorder with specific phenotypic characteristics and cardiac abnormalities, but is not considered as a cancer predisposing condition. However, in rare cases, malignancies have been described in patients with WBS, with hematologic cancer (mainly Burkitt Lymphoma and Acute Lymphoblastic Leukemia) as the most represented. We report here the case of a boy with WS and B-NHL. This is the unique case within the large cohort of patients (n = 117) followed in our institution for long time (mean clinical follow-up, 13 years). We herewith propose that the BCL7B gene, located in the chromosomal region commonly deleted in Williams syndrome, could potentially have a role in this particular association.

Ischemic Stroke in Williams-Beuren Syndrome: A Case Report
Directory of Open Access Journals (Sweden)
Wei-Der Lee
2009-04-01
Full Text Available A 15-year-old girl was admitted because of an acute onset of facial palsy and right hemiparesis. The patient had a history of moderate mental retardation and developmental delay. On admission, her vital signs were stable, except for high blood pressure. Magnetic resonance imaging demonstrated an infarct involving the left internal capsule and putamen. Because of the patient's young age, an extensive stroke survey was performed. Williams-Beuren syndrome was finally confirmed by fluorescent in situ hybridization. Compared with the previously reported cases, no evidence of cerebral arterial stenosis or cardiac abnormalities was found by noninvasive imaging techniques. Because Williams-Beuren syndrome is a complex, multiple congenital anomaly syndrome with prominent cardiovascular features, regular assessment and antihypertensive treatment are necessary to minimize the lifelong cardiovascular risk in patients with this syndrome.

The overarching goal of this review is to compare and contrast the cognitive-behavioral features of fragile X syndrome (FraX) and Williams syndrome and to review the putative neural and molecular underpinnings of these features. Information is presented in a framework that provides guiding principles for conceptualizing gene-brain-behavior associations in neurodevelopmental disorders. Abnormalities, in particular cognitive-behavioral domains with similarities in underlying neurodevelopmental correlates, occur in both FraX and Williams syndrome including aberrant frontostriatal pathways leading to executive function deficits, and magnocellular/dorsal visual stream, superior parietal lobe, inferior parietal lobe, and postcentral gyrus abnormalities contributing to deficits in visuospatial function. Compelling cognitive-behavioral and neurodevelopmental contrasts also exist in these two disorders, for example, aberrant amygdala and fusiform cortex structure and function occurring in the context of contrasting social behavioral phenotypes, and temporal cortical and cerebellar abnormalities potentially underlying differences in language function. Abnormal dendritic development is a shared neurodevelopmental morphologic feature between FraX and Williams syndrome. Commonalities in molecular machinery and processes across FraX and Williams syndrome occur as well - microRNAs involved in translational regulation of major synaptic proteins; scaffolding proteins in excitatory synapses; and proteins involved in axonal development. Although the genetic variations leading to FraX and Williams syndrome are different, important similarities and contrasts in the phenotype, neurocircuitry, molecular machinery, and cellular processes in these two disorders allow for a unique approach to conceptualizing gene-brain-behavior links occurring in neurodevelopmental disorders.

Quantification of Interbasin Transfers into the Addicks Reservoir during Hurricane Harvey
Sebastian, A.; Juan, A.; Gori, A.; Maulsby, F.; Bedient, P. B.
2017-12-01
Between August 25 and 30, Hurricane Harvey dropped unprecedented rainfall over southeast Texas causing widespread flooding in the City of Houston. Water levels in the Addicks and Barker reservoirs, built in the 1940s to protect downtown Houston, exceeded previous records by approximately 2 meters. Concerns regarding structural integrity of the dams and damage to neighbourhoods in within the reservoir pool resulted in controlled releases into Buffalo Bayou, flooding an estimated 4,000 additional structures downstream of the dams. In 2016, during the Tax Day it became apparent that overflows from Cypress Creek in northern Harris County substantially contribute to water levels in Addicks. Prior to this event, little was known about the hydrodynamics of this overflow area or about the additional stress placed on Addicks and Barker reservoirs due to the volume of overflow. However, this information is critical for determining flood risk in Addicks Watershed, and ultimately Buffalo Bayou. In this study, we utilize the recently developed HEC-RAS 2D model the interbasin transfer that occurs between Cypress Creek Watershed and Addicks Reservoir to quantify the volume and rate at which water from Cypress enters the reservoir during extreme events. Ultimately, the results of this study will help inform the official hydrologic models used by HCFCD to determine reservoir operation during future storm events and better inform residents living in or above the reservoir pool about their potential flood risk.

Williams syndrome is caused by the deletion of 26 to 28 genes, including elastin, on human chromosome 7. Elastin insufficiency leads to the cardiovascular hallmarks of this condition, namely focal stenosis and hypertension. Extrapolation from the Eln(+/-) mouse suggests that affected people may also have stiff vasculature, a risk factor for stroke, myocardial infarction, and cardiac death. NCF1, one of the variably deleted Williams genes, is a component of the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex and is involved in the generation of oxidative stress, making it an interesting candidate modifier for vascular stiffness. Using a case-control design, vascular stiffness was evaluated by pulse wave velocity in 77 Williams cases and matched controls. Cases had stiffer conducting vessels than controls (PWilliams syndrome. Pulse wave velocity increased with age at comparable rates in cases and controls, and although the degree of vascular stiffness varied, it was seen in both hypertensive and normotensive Williams participants. Use of antihypertensive medication and extension of the Williams deletion to include NCF1 were associated with protection from vascular stiffness. These findings demonstrate that vascular stiffness is a primary vascular phenotype in Williams syndrome and that treatment with antihypertensives or agents inhibiting oxidative stress may be important in managing patients with this condition, potentially even those who are not overtly hypertensive.

Bayesian stock assessment of Pacific herring in Prince William Sound, Alaska.
Muradian, Melissa L; Branch, Trevor A; Moffitt, Steven D; Hulson, Peter-John F
2017-01-01
The Pacific herring (Clupea pallasii) population in Prince William Sound, Alaska crashed in 1993 and has yet to recover, affecting food web dynamics in the Sound and impacting Alaskan communities. To help researchers design and implement the most effective monitoring, management, and recovery programs, a Bayesian assessment of Prince William Sound herring was developed by reformulating the current model used by the Alaska Department of Fish and Game. The Bayesian model estimated pre-fishery spawning biomass of herring age-3 and older in 2013 to be a median of 19,410 mt (95% credibility interval 12,150-31,740 mt), with a 54% probability that biomass in 2013 was below the management limit used to regulate fisheries in Prince William Sound. The main advantages of the Bayesian model are that it can more objectively weight different datasets and provide estimates of uncertainty for model parameters and outputs, unlike the weighted sum-of-squares used in the original model. In addition, the revised model could be used to manage herring stocks with a decision rule that considers both stock status and the uncertainty in stock status.

Hurricanes and related storm surges have devastating effects on near-shore infrastructure and above-ground installations. They also heavily impact groundwater resources, with potentially millions of people dependant on these resources as a freshwater source. Destructions of casings and direct incursions of saline and/or polluted waters have been widely observed. It is uncertain how extensive the effects are on underground water systems, especially in limestone karst areas such as Florida and Puerto Rico. Here, we report regional-scale water level changes in groundwater systems of Texas, Florida and Puerto Rico for the 2017 Hurricanes Harvey, Irma, Jose and Maria. We collected regional scale data from the USGS Waterdata portal. Puerto Rico shows the strongest increase in groundwater levels in wells during Hurricane Maria, with less reaction for the preceding storms Irma and Jose. Increases in water levels range from 0.5 to 11m, with maximum storm surges in Puerto Rico around 3m. These wells are located throughout Puerto Rico, on the coast and inland. In Florida, most wells that show a response during Hurricane Irma are located in the Miami region. Wells located on the west coast show smaller responses with the exception of one well located directly on Hurricane Irma's track. These wells show an increase of 0.2 to 1.7m. In Texas, wells located in proximity to Hurricane Harvey's track show an increase in water level. The effect of groundwater level increases is not limited to the Texas coast, but inland as well. An increase between 0.03 and 2.9m is seen. Storm surges for both Florida and Texas have ranged from 1.8-3.7m maximum. We discuss the findings in the context of local and regional geology and hydrogeology (presence of connected aquifer systems, faulting, presence of carbonate/karst systems etc.).

Report of Some Comets: The Discovery of Uranus and Comets by William, Caroline, and John Herschel
Pasachoff, Jay M.; Olson, R. J. M.
2011-01-01
We report on the discovery and drawings of comets by William, Caroline, and John Herschel. The first discovery, by William Herschel, in 1781 from Bath, published in the Philosophical Transactions of the Royal Society with the title "Report of a Comet," turned out to be Uranus, the first planet ever discovered, Mercury through Saturn having been known since antiquity. William's sister Caroline was given duties of sweeping the skies and turned out to be a discoverer of 8 comets in her own right, in addition to keeping William's notes. Caroline's comets were discovered from Slough between 1786 and 1797. In the process, we also discuss original documents from the archives of the Royal Society and of the Royal Astronomical Society. We conclude by showing comet drawings that we have recently attributed to John Herschel, including Halley's Comet from 1836, recently located in the Ransom Center of the University of Texas at Austin. Acknowledgments: Planetary astronomy at Williams College is supported in part by grant NNX08AO50G from NASA Planetary Astronomy.

A new approach has been designed at the Bambino Gesù Children's Hospital in Rome aimed at increasing empowerment in Williams Syndrome individuals through tutor-assisted work activities. Williams Syndrome is characterized by a combination of distinguishing physical traits, congenital anomalies, intellectual disabilities, and a specific developmental profile.This manuscript describes the case of a Williams Syndrome patient.There are only few papers in the scientific literature describing interventions targeting improvement in the quality of life of adult Williams Syndrome individuals. Therefore, this experience may prove useful to several patients, their families, and the experts helping them.We described an example of intervention aimed at guiding and facilitating a Williams Syndrome patient within a work environment, taking into consideration the peaks and valleys of these individuals' specific abilities.Based on our results, we also stressed the need to promote a set of projects and initiatives aimed at enhancing as much as possible self-sufficiency and psycho-affective balance in Williams Syndrome individuals, in order to protect their dignity and self-esteem.

Rivers swelled up beyond their historic high-water marks due to precipitation from Hurricane Harvey. We used Harvey-induced flooding to investigate the flow connectivity between the coastal Trinity River and its floodplain by measuring water depth and velocity, as well as sediment-transporting conditions on the natural levee that separates the two. River discharge within the study area peaked at a historic high of 3600 cubic meters per second on September 1, 2017. The levees on two river bends were investigated on September 3 and 4 in order to characterize the hydraulic connectivity between the channel and its floodplain during the early falling limb of this flood. On September 3, a river bend located approximately 28km upstream of the river mouth was visited. Water was overtopping the levee crest at this location, 30m away from the levee crest. This overland flow only experienced about a threefold reduction in average velocity to 0.16 m/s (in 2.2 m of water) 600m away from the levee crest. On September 4, a river bend approximately 59km upstream of the river mouth was investigated. Even though the river stage was at the National Weather Service major flood stage, the levee crest separating the river and floodplain was emergent. Regardless of this local disconnect between the river and its floodplain, substantial and variable drainage velocities were measured depending on drainage patterns controlled by local topography. Velocities measured in shallow water immediately adjacent to the emergent levee were low (< 0.05 m/s in 0.2 m of water). The highest drainage velocity ( 0.18 m/s in 1.7 m of water) associated with the upstream river-bend was measured at 750m from the channel and was similar in magnitude to those recorded for the distal inundating overland flow a day before on the downstream river-bend. Results from this work highlight the maintenance of high flow velocities across the distal floodplain even during its drainage phase. The transport of sediment

This study assessed the need for an oil spill response plan for downstream coastal communities that could be affected by oil spilled from tankers travelling in Prince William Sound, Alaska. For the purpose of oil spill contingency planning, the State of Alaska has been divided into the Kodiak and Cook Inlet sub-areas that are at risk for downstream impacts from a Prince William Sound oil spill. The 1989 Exxon Valdez oil spill provided an example of a worst-case scenario oil spill from a tanker in Prince William Sound, but the oil spill planning system that has evolved in Alaska does not adequately plan for on oil spill that originates in one sub-area of the state, but impacts other sub-areas in the downstream spill path. This study analyzed the gaps that exist in the current response planning system in the Prince William Sound, Cook Inlet and Kodiak sub-areas. A method was proposed to improve the existing response plans so that emergency response teams are better prepared to manage cross-boundary oil spills originating in Prince William Sound. The proposed method focuses on nearshore response and sensitive areas protection for coastlines and communities that are at risk for oil spills from a tanker travelling the Trans-Alaska Pipeline System (TAPS). 11 refs., 3 figs

Polarimetric Radar Retrievals in Southeast Texas During Hurricane Harvey
Wolff, D. B.; Petersen, W. A.; Tokay, A.; Marks, D. A.; Pippitt, J. L.; Kirstetter, P. E.
2017-12-01
Hurricane Harvey hit the Texas Gulf Coast as a major hurricane on August 25, 2017 before exiting the state as a tropical storm on September 1, 2017. In its wake, it left a flood of historic proportions, with some areas measuring 60 inches of rain over a five-day period. Although the storm center stayed west of the immediate Houston area training bands of precipitation impacted the Houston area for five full days. The National Weather Service (NWS) WSR88D dual-polarimetric radar (KHGX), located southeast of Houston, maintained operations for the entirety of the event. The Harris County Flood Warning System (HCFWS) had 150 rain gauges deployed in its network and seven NWS Automated Surface Observing Systems (ASOS) rain gauges are also located in the area. In this study, we used the full radar data set to retrieve daily and event-total precipitation estimates within 120 km of the KHGX radar for the period August 25-29, 2017. These estimates were then compared to the HCFWS and ASOS gauges. Three different polarimetric hybrid rainfall retrievals were used: Ciffeli et al. 2011; Bringi et al. 2004; and, Chen et al. 2017. Each of these hybrid retrievals have demonstrated robust performance in the past. However, both daily and event-total comparisons from each of these retrievals compared to those of HCFWS and ASOS rain gauge networks resulted in significant underestimates by the radar retrievals. These radar underestimates are concerning. Sources of error and variance will be investigated to understand the source of radar-gauge disagreement. One current hypothesis is that due to the large number of small drops often found in hurricanes, the differential reflectivity and specific differential phase are relatively small so that the hybrid algorithms use only the reflectivity/rain rate procedure (so called Z-R relationships), and hence rarely invoke the ZDR or KDP procedures. Thus, an alternative Z-R relationship must be invoked to retrieve accurate rain rate estimates.

Our knowledge regarding the anatomophysiology of the cardiovascular system (CVS) has progressed since the fourth millennium BC. In Egypt (3500 BC), it was believed that a set of channels are interconnected to the heart, transporting air, urine, air, blood, and the soul. One thousand years later, the heart was established as the center of the CVS by the Hippocratic Corpus in the medical school of Kos, and some of the CVS anatomical characteristics were defined. The CVS was known to transport blood via the right ventricle through veins and the pneuma via the left ventricle through arteries. Two hundred years later, in Alexandria, following the development of human anatomical dissection, Herophilus discovered that arteries were 6 times thicker than veins, and Erasistratus described the semilunar valves, emphasizing that arteries were filled with blood when ventricles were empty. Further, 200 years later, Galen demonstrated that arteries contained blood and not air. With the decline of the Roman Empire, Greco-Roman medical knowledge about the CVS was preserved in Persia, and later in Islam where, Ibn Nafis inaccurately described pulmonary circulation. The resurgence of dissection of the human body in Europe in the 14th century was associated with the revival of the knowledge pertaining to the CVS. The main findings were the description of pulmonary circulation by Servetus, the anatomical discoveries of Vesalius, the demonstration of pulmonary circulation by Colombo, and the discovery of valves in veins by Fabricius.

Williams syndrome (OMIM #194050) is a rare, well-recognized, multisystemic genetic condition affecting approximately 1/7,500 individuals. There are no marked regional differences in the incidence of Williams syndrome. The syndrome is caused by a hemizygous deletion of approximately 28 genes, including ELN on chromosome 7q11.2. Prenatal-onset growth retardation, distinct facial appearance, cardiovascular abnormalities, and unique hypersocial behavior are among the most common clinical features. Here, we report the case of a patient referred to us with distinct facial features and intellectual disability, who was diagnosed with Williams syndrome at the age of 37 years. Our aim is to increase awareness regarding the diagnostic features and complications of this recognizable syndrome among adult health care providers. Williams syndrome is usually diagnosed during infancy or childhood, but in the absence of classical findings, such as cardiovascular anomalies, hypercalcemia, and cognitive impairment, the diagnosis could be delayed. Due to the multisystemic and progressive nature of the syndrome, accurate diagnosis is critical for appropriate care and screening for the associated morbidities that may affect the patient's health and well-being.

Williams syndrome is a genetic disorder associated with cardiac pathology, including supravalvular aortic stenosis and coronary artery stenosis. Sudden cardiac death has been reported in the perioperative period and attributed to cardiovascular pathology. In this retrospective audit, case note and anaesthetic records were reviewed for all confirmed Williams syndrome patients who had received an anaesthetic in our institution between July 1974 and November 2009. There were a total of 108 anaesthetics administered in 29 patients. Twelve of the anaesthetics (11.1%) were associated with cardiac complications including cardiac arrest in two cases (1.85%). Of the two cardiac arrests, one patient died within the first 24 hours postanaesthetic and the other patient survived, giving an overall mortality of 0.9% (3.4%). We conclude that Williams syndrome confers a significant anaesthetic risk, which should be recognised and considered by clinicians planning procedures requiring general anaesthesia.

Observations of Building Performance under Combined Wind and Surge Loading from Hurricane Harvey
Lombardo, F.; Roueche, D. B.; Krupar, R. J.; Smith, D. J.; Soto, M. G.
2017-12-01
Hurricane Harvey struck the Texas coastline on August 25, 2017, as a Category 4 hurricane - the first major hurricane to reach the US in twelve years. Wind gusts over 130 mph and storm surge as high as 12.5 ft caused widespread damage to buildings and critical infrastructure in coastal communities including Rockport, Fulton, Port Aransas and Aransas Pass. This study presents the methodology and preliminary observations of a coordinated response effort to document residential building performance under wind and storm surge loading. Over a twelve day survey period the study team assessed the performance of more than 1,000 individual, geo-located residential buildings. Assessments were logged via a smartphone application to facilitate rapid collection and collation of geotagged photographs, building attributes and structural details, and structural damage observations. Detailed assessments were also made of hazard intensity, specifically storm surge heights and both wind speed and direction indicators. Preliminary observations and findings will be presented, showing strong gradients in damage between inland and coastal regions of the affected areas that may be due in part to enhanced individual loading effects of wind and storm surge and potentially joint-hazard loading effects. Contributing factors to the many cases of disproportionate damage observed in close proximity will also be discussed. Ongoing efforts to relate building damage to near-surface hazard measurements (e.g., radar, anemometry) in close proximity will also be described.

Multiple regions of Harvey sarcoma virus RNA can dimerize in vitro.
Feng, Y X; Fu, W; Winter, A J; Levin, J G; Rein, A
1995-04-01
Retroviruses contain a dimeric RNA consisting of two identical molecules of plus-strand genomic RNA. The structure of the linkage between the two monomers is not known, but they are believed to be joined near their 5' ends. Darlix and coworkers have reported that transcripts of retroviral RNA sequences can dimerize spontaneously in vitro (see, for example, E. Bieth, C. Gabus, and J. L. Darlix, Nucleic Acids Res. 18:119-127, 1990). As one approach to identification of sequences which might participate in the linkage, we have mapped sequences derived from the 5' 378 bases of Harvey sarcoma virus (HaSV) RNA which can dimerize in vitro. We found that at least three distinct regions, consisting of nucleotides 37 to 229, 205 to 272, and 271 to 378, can form these dimers. Two of these regions contain nucleotides 205 to 226; computer analysis suggests that this region can form a stem-loop with an inverted repeat in the loop. We propose that this hypothetical structure is involved in dimer formation by these two transcripts. We also compared the thermal stabilities of each of these dimers with that of HaSV viral RNA. Dimers of nucleotides 37 to 229 and 205 to 272 both exhibited melting temperatures near that of viral RNA, while dimers of nucleotides 271 to 378 are quite unstable. We also found that dimers of nucleotides 37 to 378 formed at 37 degrees C are less thermostable than dimers of the same RNA formed at 55 degrees C. It seems possible that bases from all of these regions participate in the dimer linkage present in viral RNA.

The many-sublattice Bragg-Williams approximation of statistical mechanics is applied to the two-dimensional square and triangular lattice-gas models with nearest-neighbor repulsive interactions. Each problem is solved through both the canonical and grand-canonical methods. The present treatment emphasizes the duality between concentration and chemical potential and illustrates the appearance of first- and second -order transitions in each method. (Author) [pt

A main aim of this study was to test the claim that individuals with Williams syndrome have selectively impaired memory for spatial as opposed to visual information. The performance of 16 individuals with Williams syndrome (six males, 10 females; mean age 18y 7mo [SD 7y 6mo], range 9y 1mo-30y 7mo) on tests of short-term memory for item and location information was compared with that shown by individuals with moderate learning difficulties (12 males, four females; mean age 10y 3mo [SD 1y], range 8y 6mo-11y 7mo) and typically developing children (six males, 10 females; mean age 6y 8mo [SD 7mo], range 5y 10mo-7y 9mo) of an equivalent level of visuospatial ability. A second aim was to determine whether individuals had impaired ability to 'bind' visual spatial information when required to recall 'item in location' information. In contrast to previous findings, there was no evidence that individuals with Williams syndrome were more impaired in the spatial than the visual memory condition. However, individuals with both Williams syndrome and moderate learning difficulties showed impaired memory for item in location information, suggesting that problems of binding may be generally associated with learning disability.

Williams' paradox and the role of phenotypic plasticity in sexual systems.
Leonard, Janet L
2013-10-01
As George Williams pointed out in 1975, although evolutionary explanations, based on selection acting on individuals, have been developed for the advantages of simultaneous hermaphroditism, sequential hermaphroditism and gonochorism, none of these evolutionary explanations adequately explains the current distribution of these sexual systems within the Metazoa (Williams' Paradox). As Williams further pointed out, the current distribution of sexual systems is explained largely by phylogeny. Since 1975, we have made a great deal of empirical and theoretical progress in understanding sexual systems. However, we still lack a theory that explains the current distribution of sexual systems in animals and we do not understand the evolutionary transitions between hermaphroditism and gonochorism. Empirical data, collected over the past 40 years, demonstrate that gender may have more phenotypic plasticity than was previously realized. We know that not only sequential hermaphrodites, but also simultaneous hermaphrodites have phenotypic plasticity that alters sex allocation in response to social and environmental conditions. A focus on phenotypic plasticity suggests that one sees a continuum in animals between genetically determined gonochorism on the one hand and simultaneous hermaphroditism on the other, with various types of sequential hermaphroditism and environmental sex determination as points along the spectrum. Here I suggest that perhaps the reason we have been unable to resolve Williams' Paradox is because the problem was not correctly framed. First, because, for example, simultaneous hermaphroditism provides reproductive assurance or dioecy ensures outcrossing does not mean that there are no other evolutionary paths that can provide adaptive responses to those selective pressures. Second, perhaps the question we need to ask is: What selective forces favor increased versus reduced phenotypic plasticity in gender expression? It is time to begin to look at the question

As reported previously (Namba et al., 1985), normal human fibroblasts were transformed by 60Co gamma-ray irradiation into immortal cells with abnormal karyotypes. These transformed cells (KMST-6), however, showed a low cloning efficiency in soft agar and no transplantability. However, upon treatment with Harvey murine sarcoma virus (Ha-MSV), the cells acquired elevated clonability in soft agar and transplantability in nude mice. Ha-MSV alone, however, did not convert normal human fibroblasts into either immortal or tumorigenic cells. The Ha-MSV-transformed KMST-6 cells showed an enhanced expression of the ras oncogene, but normal and 60Co gamma-ray-transformed cells did not. Our current data suggest that gamma rays worked against normal human cells as an initiator, giving rise to chromosome aberrations and immortality, and that Ha-MSV, probably through its ras oncogene, played a role in the progression of the malignant cell population to a more malignant one showing enhanced colony formation in soft agar and tumorigenicity in nude mice.

Random Thoughts on William Shakespeare and Medicine
KV Sahasranam
2017-01-01
Medicine and literature have always been connected over the ages. William Shakespeare (1564-1616) is no exception. There are plenty of references to medicine and diseases in the works of Shakespeare. The knowledge which Shakespeare has of medical conditions is much more than is expected of a common man. This is attributed to his association with practitioners of his time and reading of contemporary texts in medicine. Also his son in law Dr. John Hall who married Susanna, Shakespeare's eldest ...

A software package for mapping digital data 'layers' of environmentally and/or culturally sensitive areas such as seabird colonies, seal haulouts, and sea otter concentrations in Prince William Sound and adjoining areas of southern Alaska has been developed by the Alyeska Pipeline Service Company. The data is to be added to an environmental computer mapping database. More than 1,800 known and reported coastal cultural resource sites have been identified. The database is part of the Prince William Sound Tanker Oil Discharge Prevention and Contingency Plan. The mappable data layers can be used to plan and execute whatever site protection program may be necessary, thus enhancing effective cultural resource protection during an oil spill response. 22 refs., 4 figs

Full Text Available Our knowledge regarding the anatomophysiology of the cardiovascular system (CVS has progressed since the fourth millennium BC. In Egypt (3500 BC, it was believed that a set of channels are interconnected to the heart, transporting air, urine, air, blood, and the soul. One thousand years later, the heart was established as the center of the CVS by the Hippocratic Corpus in the medical school of Kos, and some of the CVS anatomical characteristics were defined. The CVS was known to transport blood via the right ventricle through veins and the pneuma via the left ventricle through arteries. Two hundred years later, in Alexandria, following the development of human anatomical dissection, Herophilus discovered that arteries were 6 times thicker than veins, and Erasistratus described the semilunar valves, emphasizing that arteries were filled with blood when ventricles were empty. Further, 200 years later, Galen demonstrated that arteries contained blood and not air. With the decline of the Roman Empire, Greco-Roman medical knowledge about the CVS was preserved in Persia, and later in Islam where, Ibn Nafis inaccurately described pulmonary circulation. The resurgence of dissection of the human body in Europe in the 14th century was associated with the revival of the knowledge pertaining to the CVS. The main findings were the description of pulmonary circulation by Servetus, the anatomical discoveries of Vesalius, the demonstration of pulmonary circulation by Colombo, and the discovery of valves in veins by Fabricius. Following these developments, Harvey described blood circulation.

2002-08-01
Full Text Available We report the case of a 7-year-old male child diagnosed with Williams-Beuren syndrome and arterial hypertension refractory to clinical treatment. The diagnosis was confirmed by genetic study. Narrowing of the descending aorta and stenosis of the renal arteries were also diagnosed. Systemic vascular alterations caused by deletion of the elastin gene may occur early in individuals with Williams-Beuren syndrome, leading to the clinical manifestation of systemic arterial hypertension refractory to drug treatment.

By employing the dissociation energy and the equilibrium bond length for a diatomic molecule as explicit parameters, we generate an improved form of the Williams-Poulios potential energy model. It is found that the negative Williams-Poulios potential model is equivalent to the Manning-Rosen potential model for diatomic molecules. We observe that the Manning-Rosen potential is superior to the Morse potential in reproducing the interaction potential energy curves for the {{a}3 Σu+} state of the 6Li2 molecule and the {{X}1 sum+} state of the SiF+ molecule.

A child of Williams-Beuren syndrome for inguinal hernia repair: Perioperative management concerns
Directory of Open Access Journals (Sweden)
Sangeeta Deka
2016-01-01
Full Text Available Williams-Beuren syndrome, commonly known as Williams syndrome (WS, is a multi-organ disorder. The principal anomalies of the syndrome are developmental delay, unusual craniofacial dysmorphic features, and cardiovascular anomalies such as valvular or supravalvular aortic stenosis, pulmonary artery stenosis, and coronary insufficiency. Sudden cardiac death during minor procedures even in the absence of gross cardiovascular pathology is the most dreaded complication in these patients. A 7-year-old child with WS was posted for left-sided inguinal hernia repair under general anesthesia. Our article describes the uneventful perioperative course of the patient and highlights the concerns and complications that may be an integral part with the syndrome.

Williams syndrome (WS) is a multisystem disorder caused by deletion of about 1.55 Mb of DNA (including 26 genes) on chromosome 7q11.23, a region predisposed to recombination due to its genomic structure. Deletion of the Williams syndrome chromosome region (WSCR) occurs sporadically. To better define chance for familial recurrence and to investigate the prevalence of genomic rearrangements of the region, 257 children with WS and their parents were studied. We determined deletion size in probands by metaphase FISH, parent-of-origin of the deleted chromosome by molecular genetic methods, and inversion status of the WSCR in both parents by interphase FISH. The frequency of WSCR inversion in the transmitting parent group was 24.9%. In contrast, the rate of inversion in the non-transmitting parent group (a reasonable estimate of the rate in the general population) was 5.8%. There were no significant gender differences with respect to parent-of-origin for the deleted chromosome or the incidence of the inversion polymorphism. There was no difference in the rate of spontaneous abortion for mothers heterozygous for the WSCR inversion relative to mothers without the inversion. We calculate that for a parent heterozygous for a WSCR inversion, the chance to have a child with WS is about 1 in 1,750, in contrast to the 1 in 9,500 chance for a parent without an inversion.

2017-09-28
This study examined the spontaneous use of allocentric and egocentric frames of reference and their flexible use as a function of instructions. The computerized spatial reference task created by Heiz and Barisnikov (2015) was used. Participants had to choose a frame of reference according to three types of instructions: spontaneous, allocentric and egocentric. The performances of 16 Williams Syndrome participants between 10 and 41 years were compared to those of two control groups (chronological age and non-verbal intellectual ability). The majority of Williams Syndrome participants did not show a preference for a particular frame of reference. When explicitly inviting participants to use an allocentric frame of reference, all three groups showed an increased use of the allocentric frame of reference. At the same time, an important heterogeneity of type of frame of reference used by Williams Syndrome participants was observed. Results demonstrate that despite difficulties in the spontaneous use of allocentric and egocentric frames of reference, some Williams Syndrome participants show flexibility in the use of an allocentric frame of reference when an explicit instruction is provided. © The Author 2017.

Full Text Available In Carpenter’s Gothic, hatred is given pride of place. William Gaddis delineates a society in which hatred proliferates. Characters are caught in the turmoils of their hatred whether it derives from the Vietnam War or from fundamentalist movements, from their individualistic quest for social recognition or from self-aggrandizement. We mean to develop a typology derived from psychoanalysis and anthropology so as to take into account all the different facets hate has in the novel. We shall devote analyses to jealousy caused by hatred, then describe the primary hate that underpins all types of relationships as a preliminary to questioning the excess that fuels Gaddis’s writing. Lastly, by referring to the author’s non-fictional work we shall put forward the thesis that the voluble protagonist is to a large extent the author’s mouthpiece. McCandless’s vindictive disquisitions on the course of the world will be seen as the equivalent of a tragic mask through which William Gaddis gives vent to his melancholia and intense detestation of the ways of the world.

[From Vesalius to Descartes: the heart, the life].
Bitbol-Hespériès, Annie
2014-01-01
At the end of 1629, Descartes, settled in the Lower Countries, began studying anatomy and performing dissections in order to write L'Homme (The Treatise on Man). He acknowledged his debt towards "Vezalius and the others". In those years, in Europe, the influence of Vesalius was increasing, as shown by Rembrandt's Anatomy of Dr Tulp and by the Theatrum anatomicum by Caspar Bauhin. Descartes rejected the divisions of the soul, then a common place in medical treatises, and he stated a principle of life defined by the heath in the heart linked to the new demonstration of the circulation of the blood by William Harvey.

Previous studies have suggested that Williams syndrome and Down syndrome may be associated with specific short-term memory deficits. Individuals with Williams syndrome perform relatively poorly on tests of visuo-spatial short-term memory and individuals with Down syndrome show a relative deficit on verbal short-term memory tasks. However, these patterns of impairments may reflect the impact of generally impaired visuo-spatial processing skills in Williams syndrome, and verbal abilities in Down syndrome. The current study explored this possibility by assessing long-term memory among 15 individuals with Williams syndrome and 20 individuals with Down syndrome using the Doors and People test, a battery which assesses recall and recognition of verbal and visual information. Individuals' performance was standardised for age and level of intellectual ability with reference to that shown by a sample of 110 typically developing children. The results showed that individuals with Down syndrome have no differential deficits in long-term memory for verbal information, implying that verbal short-term memory deficits in this population are relatively selective. Instead both individuals with Down syndrome and with Williams syndrome showed some evidence of relatively poor performance on tests of long-term memory for visual information. It is therefore possible that visuo-spatial short-term memory deficits that have previously been demonstrated in Williams syndrome may be secondary to more general problems in visuo-spatial processing in this population.

The burden of this dissertation is to show that William Sheldon's somatotype project should be seen as an integral aspect of modernist culture. Sheldon engaged the same problems with modernity and the "Second Industrial Revolution" (urbanization, overpopulation, industrialization, alienation) that confronted modernist poets, novelists, and philosophers. In this I am elaborating Dorothy Ross's recent metaphor, "modernist impulses in the human sciences" (1994). Both scientists and artists were ...

Williams-Beuren syndrome is characterized by mild mental retardation, specific neurocognitive profile, hypercalcemia during infancy, distinctive facial features and cardiovascular diseases. We report on complete ophthalmologic, sonographic and genetic evaluation of a girl with a clinical phenotype of Williams-Beuren syndrome, associated with unilateral anterior segment dysgenesis and bilateral cleft of the soft and hard palate. These phenotypic features have not been linked to the haploinsufficiency of genes involved in the microdeletion. A term born girl presented at the initial examination with clouding of the right cornea. On ultrasound biomicroscopy the anterior chamber structures were difficult to differentiate, showing severe adhesions from the opacified cornea to the iris with a kerato-irido-lenticular contact to the remnant lens, a finding consistent with Peters' anomaly. Genetic analyses including FISH confirmed a loss of the critical region 7q11.23, usually associated with the typical Williams-Beuren syndrome. Microsatellite analysis showed a loss of about 2.36 Mb. A diagnosis of Williams-Beuren syndrome was made based on the microdeletion of 7q11.23. The unique features, including unilateral microphthalmia and anterior segment dysgenesis, were unlikely to be caused by the microdeletion. Arguments in favor of the latter are unilateral manifestation, as well as the fact that numerous patients with deletions of comparable or microscopically visible size have not shown similar manifestations.

During an ongoing natural disaster data are required on: (1) the current situation (nowcast); (2) its likely immediate evolution (forecast); and (3) a consistent view post-event of what actually happened (hindcast or reanalysis). We describe methods used to achieve all three tasks for flood inundation during the Harvey and Irma events using a continental scale 2D hydrodynamic model (Wing et al., 2017). The model solves the local inertial form of the Shallow Water equations over a regular grid of 1 arcsecond ( 30m). Terrain data are taken from the USGS National Elevation Dataset with known flood defences represented using the U.S. Army Corps of Engineers National Levee Dataset. Channels are treated as sub-grid scale features using the HydroSHEDS global hydrography data set. The model is driven using river flows, rainfall and coastal water levels. It simulates river flooding in basins > 50 km2, and fluvial and coastal flooding everywhere. Previous wide area validation tests show this model to be capable of matching FEMA maps and USGS local models built with bespoke data with hit rates of 86% and 92% respectively (Wing et al., 2017). Boundary conditions were taken from NOAA QPS data to produce nowcast and forecast simulations in near real time, before updating with NOAA observations to produce the hindcast. During the event simulation results were supplied to major insurers and multi-nationals who used them to estimate their likely capital exposure and to mitigate flood damage to their infrastructure whilst the event was underway. Simulations were validated against modelled flood footprints computed by FEMA and USACE, and composite satellite imagery produced by the Dartmouth Flood Observatory. For the Harvey event, hit rates ranged from 60-84% against these data sources, but a lack of metadata meant it was difficult to perform like-for-like comparisons. The satellite data also appeared to miss known flooding in urban areas that was picked up in the models. Despite

Full Text Available As sociologias da literatura de Bourdieu e Williams estão apoiadas em dois conceitos fundamentais: “habitus” e “estruturas de sentimento”, respectivamente. E é clara a semelhança entre eles: ambos tentam traduzir uma espécie de consciência prática adquirida pelos agentes sociais a partir de um processo particular de socialização. Para o primeiro, o “habitus” é internalizado na experiência vivida num campo específi co; ao passo que, para o segundo, tal consciência é formada no interior dos grupos culturais. Nesse sentido, ambas as noções dizem respeito a um conjunto de valores compartilhados que aproximam e afastam certos agentes uns dos outros, criando solidariedade e rivalidades. Esta comunicação pretende demonstrar que, apesar das diferenças que existem, os conceitos dos autores não supervalorizam nem a reprodução nem a mudança social, mas, ao contrário, tentam explicar esses fenômenos como jogo dialético. Palavras-chave: Pierre Bourdieu. Raymond Williams. Sociologia da literatura. “Habitus”. Estruturas de sentimento. The literature sociologies of Bourdieu and Williams are structured in two fundamental concepts: “habitus” and “sentiment structures”, respectively. It’s very clear the resemblance between them: both try to translate a kind of practical conscience, acquired by the social agents from a particular socializing process. To the fi rst, the “habitus” is internalized in the living experience of a specifi c fi eld; while that to the second that conscience is formed in the interior of cultural groups. In this sense, both ideas talk about shared values which approximate and withdraw some agents one from the others, creating solidarity and competition. This text intends to show that, despite of the existing differences, the authors concepts don’t overestimate neither the reproduction, nor the social change, but, otherwise, try to explain these phenomena as a dialectic game.

Differential vulnerability is a concept that suggests that certain demographic groups - the poor, less educated, or minorities - are likely to be more impacted by climate extremes such as floods owing to their higher sensitivity and lower adaptive capacity. Differential exposure represents the concept that these same groups may be more highly exposed to flood events by virtue of their residing in less desirable, low-lying neighborhoods with higher percentages of impervious surface cover. This paper tests the hypothesis that poor communities of color were differentially exposed to flood risks in the aftermath of Hurricane Harvey, which struck Houston, Texas in August 2017. We explore the spatial relationship among census tracts with high percentages of low income communities of color, those with high percentages of impervious surface, and those most impacted by floods. We incorporat datasets disseminated by the NASA Socioeconomic Data and Application Center (SEDAC) - the Global Man-made Impervious Surface (GMIS) data set and the U.S. Census Grids 2010 - together with the American Community Survey (ACS) 2011-2015 and flood extent and depth data from FEMA. Preliminary analysis suggests that predominantly non-white neighborhoods have higher percentages of impervious surface cover, but that impervious surface cover is negatively correlated with flood risk. This paper will situate these findings in the context of a larger body of research exploring differential exposure to flood risks during Hurricanes Katrina and Sandy, as well as differential exposure to extreme heat in urban environments in Houston and beyond.

The launch of CYGNSS (Cyclone Global Navigation Satellite System) has added an interesting component to satellite observations: it can provide wind speeds in the tropical area with a high repetition rate. Passive microwave sounders that are overpassing the same region can benefit from this information, when it comes to the retrieval of temperature or water profiles: the uncertainty about wind speeds has a strong impact on emissivity and reflectivity calculations with respect to surface temperature. This has strong influences on the uncertainty of retrieval of temperature and water content, especially under extreme weather conditions. Adding CYGNSS information to the retrieval can help to reduce errors and provide a significantly better sounder retrieval. Based on observations during Hurricane Harvey, we want to show the impact of CYGNSS data on the retrieval of passive microwave sensors. We will show examples on the impact on the retrieval from polar orbiting instruments, like the Advanced Technology Microwave Sounder (ATMS) and AMSU-A/B on NOAA-18 and 19. In addition we will also show the impact on retrievals from HAMSR (High Altitude MMIC Sounding Radiometer), which was flying on the Global Hawk during the EPOCH campaign. We will compare the results with other observations and estimate the impact of additional CYGNSS information on the microwave retrieval, especially on the impact in error and uncertainty reduction. We think, that a synergetic use of these different data sources could significantly help to produce better assimilation products for forecast assimilation.

Sir William Osler's speech at Troy: a Trojan horse?
Moran, Michael E
2012-01-01
Troy, New York, is a city of 55,000 people in upstate New York located along the Hudson River. A city of surprisingly rich cultural heritage, it was the home of New York state's first hospital outside New York City. The 50th anniversary celebration of Troy's hospital brought William Osler to the city as the keynote speaker. This speech, delivered on November 28, 1900, is one of Sir William's less well known addresses. Osler began his comments with Sir Thomas More's Utopia and talked at length about the hospital, its obligations, the influences it has upon the community, and the role of physicians and surgeons. He broached one of his old saws, the salary of attending physicians and their needed role in hospital management. His words were published in the diamond jubilee's records, but the hospital did not outlive its prominent guest professor, and it closed its doors in 1914. Just like the great historical city of Troy, New York's own Troy was on the brink of decline, and its hospital would be the first fatality. Therefore, it is almost prescient that the words of Osler, taken into historical context juxtaposed against the socioeconomic forces at work, are akin to the Greek's offering of a wooden edifice to end the Trojan War.

Shoreline oiling conditions in Prince William Sound following the Exxon Valdez oil spill
International Nuclear Information System (INIS)
Neff, J.M.; Owens, E.H.; Stoker, S.W.; McCormick, D.M.
1995-01-01
Following the Exxon Valdez oil spill of March 24, 1989, in Prince William Sound, Alaska, Exxon conducted comprehensive, systematic shoreline surveys in cooperation with federal and state authorities to obtain information on the distribution and magnitude of shoreline oiling and to identify natural and cultural resources requiring special protection. Similar joint surveys were performed during the springs of 1990, 1991, and 1992 on all Prince william Sound and Gulf of Alaska shorelines that were suspected of having remnants of weathered oil and that would benefit from further cleanup. In the springs of 1990, 1991, and 1992, isolated pockets of subsurface oil were found, chiefly in small scattered zones in coarse cobble/boulder sediments in the upper intertidal or supratidal zones. In 1991, about one-third of the subdivisions in Prince William Sound with surface oil also contained some subsurface oil. The areal extent of this subsurface oil declined by nearly 70% between 1991 and 1992, from about 37,000 m 2 to about 12,000 m 2 . Moreover, where subsurface oil remained in 1992, it was present in lesser amounts. Rates of oil removal were greatest on coastal sections treated early in the spring and summer of 1989. Where shoreline treatment was delayed, the subsequent rate of removal of oil from the shore by natural processes was slower. 27 refs., 10 figs., 3 tabs

Genes, language, and the nature of scientific explanations: the case of Williams syndrome.
Musolino, Julien; Landau, Barbara
2012-01-01
In this article, we discuss two experiments of nature and their implications for the sciences of the mind. The first, Williams syndrome, bears on one of cognitive science's holy grails: the possibility of unravelling the causal chain between genes and cognition. We sketch the outline of a general framework to study the relationship between genes and cognition, focusing as our case study on the development of language in individuals with Williams syndrome. Our approach emphasizes the role of three key ingredients: the need to specify a clear level of analysis, the need to provide a theoretical account of the relevant cognitive structure at that level, and the importance of the (typical) developmental process itself. The promise offered by the case of Williams syndrome has also given rise to two strongly conflicting theoretical approaches-modularity and neuroconstructivism-themselves offshoots of a perennial debate between nativism and empiricism. We apply our framework to explore the tension created by these two conflicting perspectives. To this end, we discuss a second experiment of nature, which allows us to compare the two competing perspectives in what comes close to a controlled experimental setting. From this comparison, we conclude that the "meaningful debate assumption", a widespread assumption suggesting that neuroconstructivism and modularity address the same questions and represent genuine theoretical alternatives, rests on a fallacy.

Description of common musculoskeletal findings in Williams Syndrome and implications for therapies.
Copes, L E; Pober, B R; Terilli, C A
2016-07-01
Williams syndrome (WS), also referred to as Williams-Beuren syndrome (WBS), is a relatively rare genetic disorder affecting ∼1/10,000 persons. Since the disorder is caused by a micro-deletion of ∼1.5 Mb, it is not surprising that the manifestations of WS are extremely broad, involving most body systems. In this paper, we primarily focus on the musculoskeletal aspects of WS as these findings have not been the subject of a comprehensive review. We review the MSK features commonly seen in individuals with WS, along with related sensory and neurological issues interacting with and compounding underlying MSK abnormalities. We end by providing perspective, particularly from the vantage point of a physical therapist, on therapeutic interventions to address the most common MSK and related features seen in WS. Clin.

PTBA stock prices are influenced by fundamental conditions such as limited supply of fuel which is rumored and coal is the main alternative fuels other than oil. Study period was 241 trade days. Data are analyzed in several periods and then fitted with the MACD indicator and Williams % R, then simulate the trade during the period of research studies to determine the level of trading profits or losses based on the combination of both these technical indicators. The conclusion of this analysis, the MACD is an indicator that is considered slow (lagging in giving an indication of weakness, but in reverse the MACD is considered to provide an accurate indication of where the indication given is rarely wrong. Williams% R is an rapid indicator in anticipation of a reversal trend, but these indicators often give a false indication since this indicator is quite sensitive to the movement of stock prices goings go up or down.

MÉTODOS: Setenta fibrocísticos foram acompanhados prospectivamente e submetidos a exame clínico, bioquímico e ultra-sonográfico. Os achados ultra-sonográficos foram comparados com os resultados do exame clínico e bioquímico. Para a validação do escore ultra-sonográfico de Williams, os critérios clínicos e bioquímicos foram utilizados como padrão-ouro. Foram calculados sensibilidade, especificidade, valor preditivo positivo e valor preditivo negativo do escore de Williams. Para os cálculos, os pacientes foram divididos em dois grupos: normal ao exame ultra-sonográfico (escore = 3 ou alterado (escore > 3. RESULTADOS: Dez pacientes preencheram os critérios clínicos e/ou bioquímicos para hepatopatia (14,3%. Todos os pacientes hepatopatas segundo os critérios clínicos e/ou bioquímicos apresentavam alguma alteração ao exame ultra-sonográfico. As alterações do parênquima hepático, borda hepática e fibrose periportal foram encontradas mais freqüentemente entre os hepatopatas, com diferença estatisticamente significativa. O escore de Williams apresentou alta especificidade (91,7%; IC 80,9-96,9, mas baixa sensibilidade (s = 50%; IC 20,1-79,9 para o diagnóstico da hepatopatia. CONCLUSÕES: O escore de Williams não constituiu um bom exame de triagem quando comparado ao exame clínico e bioquímico.

WILLIAM HAZLITT, OBSESSIVE LOVE, AND LIBER AMORIS.
Trosman, Harry
2017-07-01
William Hazlitt, a distinguished literary figure of the early nineteenth century and a forerunner of psychoanalytic insights, had a keen awareness of the impact of the imagination on assessing works of art. At forty-two, he became hopelessly involved in an obsessive love affair with a nineteen-year-old woman and could not extricate himself from the relationship. The affair followed the death of his father, a powerful influence on his life. Factors in his obsessive love included finding an object of idealization subject to his imaginative creation and narcissistically reexperiencing himself about to begin a new life. © 2017 The Psychoanalytic Quarterly, Inc.

[Sir Geoffrey Keynes 1887-1982. Surgical pioneer, medical historian, humanist].
Bergljung, Lars
2005-01-01
Sir Geoffrey Keynes (1887 - 1982), was a pioneer in the surgery of breast cancer and thymic deseases, n.b. in patients suffering from myastenia gravis. He strongly disapproved of the longstanding dogma of so called radical mastectomy in breast cancer, and advocated a more limited surgical approach, followed by radiation therapy. This was done more than fifty years before breastconserving surgery has become the therapy of choice and against considerable opposition from the surgical establishment of his days. He also became a pioneer in the surgical treatment of myastenia gravis by thymectomy, at a time when there was no real understanding of the pathophysiology of the disease and when considerable controversy existed as to the importance or non importance of concomitant tumour formation in the thymus. Besides being a busy surgeon Sir Geoffrey was a medical historian, writing the biography of among others William Harvey, a bibliographer with a special interest in the poet and artist William Blake and a bibliophil with a large book collection of great value to medical history.

Audiological follow-up of 24 patients affected by Williams syndrome.
Barozzi, Stefania; Soi, Daniela; Spreafico, Emanuela; Borghi, Anna; Comiotto, Elisabetta; Gagliardi, Chiara; Selicorni, Angelo; Forti, Stella; Cesarani, Antonio; Brambilla, Daniele
2013-09-01
Williams syndrome is a neurodevelopmental disorder associated with cardiovascular problems, facial abnormalities and several behavioural and neurological disabilities. It is also characterized by some typical audiological features including abnormal sensitivity to sounds, cochlear impairment related to the outer hair cells of the basal turn of the cochlea, and sensorineural or mixed hearing loss, predominantly in the high frequency range. The aim of this report is to describe a follow-up study of auditory function in a cohort of children affected by this syndrome. 24 patients, aged 5-14 years, were tested by means of air/bone conduction pure-tone audiometry, immittance test and transient evoked otoacoustic emissions. They were evaluated again 5 years after the first assessment, and 10 of them underwent a second follow-up examination after a further 5 years. The audiometric results showed hearing loss, defined by a pure tone average >15 dB HL, in 12.5% of the participants. The incidence of hearing loss did not change over the 5-year period and increased to 30% in the patients who underwent the 10-year follow-up. Progressive sensorineural hearing loss was detected in 20% of the patients. A remarkable finding of our study regarded sensorineural hearing impairment in the high frequency range, which increased significantly from 25% to 50% of the participants over the 5-year period. The increase became even more significant in the group of patients who underwent the 10-year follow-up, by which time the majority of them (80%) had developed sensorineural hearing loss. Otoacoustic emissions were found to be absent in a high percentage of patients, thus confirming the cochlear fragility of individuals with Williams syndrome. Our study verified that most of the young Williams syndrome patients had normal hearing sensitivity within the low-middle frequency range, but showed a weakness regarding the high frequencies, the threshold of which worsened significantly over time in

Williams syndrome and its cognitive profile: the importance of eye movements
Directory of Open Access Journals (Sweden)
Van Herwegen J
2015-06-01
Full Text Available Jo Van Herwegen Department of Psychology, Kingston University London, Surrey, UK Abstract: People with Williams syndrome (WS, a rare neurodevelopmental disorder that is caused by a deletion on the long arm of chromosome 7, often show an uneven cognitive profile with participants performing better on language and face recognition tasks, in contrast to visuospatial and number tasks. Recent studies have shown that this specific cognitive profile in WS is a result of atypical developmental processes that interact with and affect brain development from infancy onward. Using examples from language, face processing, number, and visuospatial studies, this review evaluates current evidence from eye-tracking and developmental studies and argues that domain general processes, such as the ability to plan or execute saccades, influence the development of these domain-specific outcomes. Although more research on eye movements in WS is required, the importance of eye movements for cognitive development suggests a possible intervention pathway to improve cognitive abilities in this population. Keywords: Williams syndrome, eye movements, face processing, language, number, visuospatial abilities

The first spark of my desire to become a cardiologist came, believe it or not, in a third-grade art class where I was asked to draw and color the circulation of blood as depicted by 16th-century English physician William Harvey. This task enraptured me-seeing that something so beautiful could work so flawlessly. So, many years later, I remain intrigued by cardiac transplantation, the subspecialty in which I ultimately chose to anchor my career as a physician scientist. Each day I live in awe of the fact that you can remove someone's organ, place it in another, and still have that organ work beautifully, most of the time. But why does it sometimes fail?

Patients with Williams syndrome are considered at high risk for anesthesia-related adverse events. At our institution, all William syndrome patients undergoing cardiac surgical, cardiac catheterization/interventional procedures, and cardiac imaging studies are cared for by cardiac anesthesiologists. All William syndrome patients undergoing non-cardiac surgical, interventional, or imaging studies are cared for by main operating room pediatric anesthesiologists with consultative input from a cardiac anesthesiologist. We reviewed our experience with 75 patients undergoing 202 separate anesthetics for 95 non-cardiac procedures and 107 cardiac procedures from 2012 to 2016. The mean age was 7.5 ± 7.0 years and the mean weight was 22.3 ± 17.0 kg. One hundred and eighty-seven patients had a general anesthetic (92.6%). Medications used included etomidate in 26.2%, propofol in 37.6%, isoflurane in 47.5%, and sevoflurane in 68.3%. Vasopressors and inotropes were required including calcium (22.8%), dopamine (10.4%), norepinephrine (17.3%), phenylephrine (35.1%), vasopressin (0.5%), and ephedrine (5.4%). The median length of stay after anesthesia was 2.8 days (range 0-32). No adverse events occurred in 89.6% of anesthetics. There were two cases of cardiac arrest, one of which required extracorporeal life support for resuscitation. Of the non-cardiac surgical procedures, 95.7% did not have a cardiovascular adverse event. Patients with Williams syndrome are at high risk for anesthesia, especially when undergoing cardiac procedures. The risk can be mitigated with appropriate planning and adherence to the hemodynamic goals for non-cardiac surgical procedures.

A 20-month-old boy with Williams syndrome had undergone multiple surgical and catheter-based interventions for resistant peripheral pulmonary arterial stenoses with eventual bilateral stent placement and conventional balloon angioplasty. He persistently developed suprasystemic right ventricular (RV) pressure. Angioplasty with a drug-coated balloon (DCB) was performed for in-stent restenosis and to remodel his distal pulmonary vessels bilaterally. This resulted in immediate improvement in the in-stent stenosis and resultant decrease in RV pressure. Follow-up catheterization two months later continued to show long-lasting improvement in the in-stent stenosis. We hypothesize that the anti-proliferative effects of DCBs may be of benefit in the arteriopathy associated with Williams syndrome. We report this as a novel use of a DCB in the pulmonary arterial circulation in a patient with Williams syndrome.

Hurricane Harvey has been noted as the wettest cyclone on record for the US as well as the most destructive (so far) for the 2017 hurricane season. An entire year worth of rainfall occurred over the course of a few days. The city of Houston was greatly impacted as the storm lingered over the city for five days, causing a record-breaking 50+ inches of rain as well as severe damage from flooding. Flood model simulations were performed to reconstruct the event in order to better understand, assess, and predict flooding dynamics for the future. Additionally, number of remote sensing platforms, and on ground instruments that provide near real-time data have also been used for flood identification, monitoring, and damage assessment. Although both flood models and remote sensing techniques are able to identify inundated areas, rapid and accurate flood prediction at a high spatio-temporal resolution remains a challenge. Thus a methodological approach which fuses the two techniques can help to better validate what is being modeled and observed. Recent advancements in data fusion techniques of remote sensing with near real time heterogeneous datasets have allowed emergency responders to more efficiently extract increasingly precise and relevant knowledge from the available information. In this work the use of multiple sources of contributed data, coupled with remotely sensed and open source geospatial datasets is demonstrated to generate an understanding of potential damage assessment for the floods after Hurricane Harvey in Harris County, Texas. The feasibility of integrating multiple sources at different temporal and spatial resolutions into hydrodynamic models for flood inundation simulations is assessed. Furthermore the contributed datasets are compared against a reconstructed flood extent generated from the Flood2D-GPU model.

Individuals with Williams syndrome, a neurogenetic condition caused by deletion of a set of genes at chromosomal location 7q11.23, exhibit a remarkable suite of traits including hypersociality with high, nonselective friendliness and low social anxiety, expressive language relatively well-developed but under-developed social-communication skills overall, and reduced visual-spatial abilities. Deletions and duplications of the Williams-syndrome region have also been associated with autism, and with schizophrenia, two disorders centrally involving social cognition. Several lines of evidence have linked the gene GTF2I (General Transcription Factor IIi) with the social phenotypes of Williams syndrome, but a role for this gene in sociality within healthy populations has yet to be investigated. We genotyped a large set of healthy individuals for two single-nucleotide polymorphisms in the GTF2I gene that have recently been significantly associated with autism, and thus apparently exhibit functional effects on autism-related social phenotypes. GTF2I genotypes for these SNPs showed highly significant association with low social anxiety combined with reduced social-communication abilities, which represents a metric of the Williams-syndrome cognitive profile as described from previous studies. These findings implicate the GTF2I gene in the neurogenetic basis of social communication and social anxiety, both in Williams syndrome and among individuals in healthy populations.

Morphological differences in the mirror neuron system in Williams Syndrome
Ng, Rowena; Brown, Timothy T.; Erhart, Matthew; Järvinen, Anna M.; Korenberg, Julie R.; Bellugi, Ursula; Halgren, Eric
2015-01-01
Williams syndrome (WS) is a genetic condition characterized by an overly gregarious personality, including high empathetic concern for others. Although seemingly disparate from the profile of autism spectrum disorder (ASD), both are associated with deficits in social communication/cognition. Notably, the mirror neuron system (MNS) has been implicated in social dysfunction for ASD; yet, the integrity of this network and its association with social functioning in WS remains unknown.

Random Thoughts on William Shakespeare and Medicine
Directory of Open Access Journals (Sweden)
KV Sahasranam
2017-04-01
Full Text Available Medicine and literature have always been connected over the ages. William Shakespeare (1564-1616 is no exception. There are plenty of references to medicine and diseases in the works of Shakespeare. The knowledge which Shakespeare has of medical conditions is much more than is expected of a common man. This is attributed to his association with practitioners of his time and reading of contemporary texts in medicine. Also his son in law Dr. John Hall who married Susanna, Shakespeare's eldest daughter would have contributed substantially to the knowledge of medicine in Shakespeare's compositions. Surgery at the Elizabethan times was well known and is reflected to a large extent in his plays.

Using Satellite Imagery to Quantify Water Quality Impacts and Recovery from Hurricane Harvey
Sobel, R. S.; Kiaghadi, A.; Rifai, H. S.
2017-12-01
Record rainfall during Hurricane Harvey in the Houston-Galveston region generated record flows containing suspended sediment that was likely contaminated. Conventional water quality monitoring requires resource intensive field campaigns, and produces sparse datasets. In this study, satellite data were used to quantify suspended sediment (TSS) concentrations and mass within the region's estuary system and to estimate sediment deposition and transport. A conservative two band, red-green empirical regression was developed from the Sentinel 2 satellite to calculate TSS concentrations and masses. The regression was calibrated with an R2 = 0.73 (n=28) and validated with an R2 = 0.75 (n=12) using 2016 & 2017 imagery. TSS concentrations four days, 14 days, and 44 days post-storm were compared with a reference condition three days before storm arrival. Results indicated that TSS concentrations were an average of 100% higher four days post-storm, and 150% higher after 14 days, however, the average concentration on day 144 was only seven percent higher than the reference condition, suggesting the estuary system is approaching recovery to pre-storm conditions. Sediment masses were determined from the regressed concentrations and water volumes estimated from a bottom elevation grid combined with water surface elevations observed coincidently with the satellite image. While water volumes were only 13% higher on both day four and day 14 post-storm; sediment masses were 195% and 227% higher than the reference condition, respectively. By day 44, estuary sediment mass returned to just 2.9% above the reference load. From a mechanistic standpoint, the elevated TSS concentrations on day four indicated an advection-based regime due to stormwater runoff draining through the estuarine system. Sometime, however, between days 14 and 44, transport conditions switched from advection-dominated to deposition-driven as indicated by the near normal TSS concentrations on day 44.

‘Wot larx!’: William Morris, Charles Dickens, and Fatherly Feelings
Directory of Open Access Journals (Sweden)
Wendy Parkins
2011-09-01
Full Text Available This essay explores the significance of William Morris’s reading of Dickens for Morris’s articulation of fatherly feelings. Recent scholarship on Victorian fatherhood has begun to overturn the stereotype of the dour, emotionally distant paterfamilias as providing only a partial understanding of forms of middle-class fatherhood and William Morris may serve as an example of a Victorian father whose parenting style eschewed detached authoritarianism, and instead combined nurture, play, and creativity. While Morris referred to Dickens’s works and characters in letters to a range of correspondents, his repeated usage of Joe Gargery’s catchphrase ‘Wot larx!’ (variously spelled occurs exclusively in letters to his wife and daughters, especially the latter. I will consider how the character of Joe Gargery, who combines nurturing tenderness with manly labour, was deployed by Morris to perform a playful and affectionate paternal persona. While Morris’s use of Joe’s catchphrase seems to express a spontaneous overflow of powerful feeling its status as a quotation also works to mark (and mask a disavowal of powerfully ambivalent feelings concerning his own emotional agency as husband and father.

Pre-spill shoreline mapping in Prince William Sound, Alaska
International Nuclear Information System (INIS)
Owens, E.H.; Lamarche, A.; Reimer, P.D.; Marchant, S.O.; O'Brien, D.K.
2003-01-01
A long-term shoreline mapping program has been initiated in Prince William Sound, Alaska, to generate pre-spill data to assist in the planning activities for oil spill response in the area. Low-altitude aerial videotape surveys and video images form the basis for the mapping effort. The coast was initially divided into alongshore segments. The physical shore-zone is relatively homogeneous within each segment. A pre-spill Shoreline Cleanup Assessment Team (SCAT) database, using the ShoreData software, was created based on this initial detailed mapping. The SCAT field teams are therefore equipped with a detailed analysis of the shore-zone character. The same information was also used to develop a separate database for use by planning and response operations groups. The data is entered into the Graphical Resource Database (GRD), and a Geographic Information System (GIS). A simplified characterization of the primary features of each segment is then made available through interpretation of the data. In the event of an oil spill, the SCAT data in the ShoreData files can be combined with field data on shoreline oiling conditions using a second software package called ShoreAccess R which provides summaries of the main parameters required by the planning group. It can also be used as a data storage and management tool. As part of this program, more than 1700 kilometres of shoreline in Prince William Sound have already been mapped. 24 refs., 4 tabs., 5 figs

Aortic anomalies in an adolescent with the Williams' elfin facies syndrome
International Nuclear Information System (INIS)
Williams, R.L.; Azouz, E.M.
1984-01-01
An adolescent with classical Williams' syndrome who presented with hypertensive encephalopathy is described. He had the unusual combination of supravalvular aortic stenosis, long segment coarctation of the aorta, aortic hypoplasia and a high bifurcation of the abdominal aorta. Surgical resection of the coarctation was required; however, the patient has remained moderately hypertensive. The aortic anomalies in this syndrome are reviewed and their frequency and importance examined. (orig.)

Sir William Mitchell (1925-2002)
2002-01-01
Sir William (Bill) Mitchell, former President of the CERN Council, died on 30th October 2002 at the age of 77. Mitchell was professor of Physics at Oxford University from 1978 to 1989, having previously been Professor of Physics, Dean of Science and Deputy Vice-Chancellor at Reading University. From 1985 to 1990 he was Chairman of the UK's Science and Engineering Research Council (SERC), which at the time was the funding agency for the UK's participation in the CERN programme. As Chairman, Mitchell was one of the UK representatives on the CERN Council, and in 1991 he was elected President, a position he held for three years. This was a difficult period for CERN. Financial problems were being faced in many member states, notably in Germany as a result of unification. This led to calls for reductions in the CERN budget and, more significantly, to requests for delays in consderation of future programmes. On the other hand for the future of CERN and the progress of elementary particle physics, it was necessary...

David Owen Williams (1944 - 2006)
2006-01-01
Many people, not only at CERN but also throughout the world, were saddened to learn that their friend and colleague David Williams had passed away in the early hours of Tuesday 24 October. His death came after a year of fighting cancer with all of his usual determination and optimism. Even days before the end he was still welcoming to visitors, and was alert and interested in all their news. Born in 1944, David came to CERN from the University of Cambridge in 1966, with a degree in Physics and Computer Science. Joining what at the time was called the Documents and Data (DD) Division, in the earlier part his career he worked first on software for analysis of bubble chamber photographs, subsequently leading the group that supported experiments with 'hybrids' of bubble chambers and electronic detectors and then the group supporting online computing in experiments. He thus witnessed all of the enormous changes that took place in particle physics as the era of bubble chambers came to an end and the availability ...

Gedzelman, Stanley David
William L. Donn, Professor Emeritus of the Department of Earth and Planetary Sciences, City College of New York, and Special Research Scientist at Lamont-Doherty Geological Observatory (LDGO) of Columbia University (Palisades, N.Y.), died at his home on June 30, 1987, at the age of 69. Bill demonstrated expertise in a wide range of fields, with a highly productive and creative research and writing career that included geology, oceanography, climatology, atmospheric physics, and meteorology.Donn was born in Brooklyn, N.Y., on March 2, 1918. At the tender age of 10 years, he demonstrated his love and talent for science by building a telescope with his brother, Bertram. During his undergraduate years at Brooklyn College, he switched his major from astronomy to geology. He was largely selftrained in both meteorology and oceanography, serving as head of the Meteorology Section, U.S. Merchant Marine Academy during World War II . One by-product of these years was the textbook Meteorology—With Marine Applications, first published in 1946. This widely adopted text became a standard for a generation of mariners and college students.

Liu, Ze-Sheng; Liu, Ze-En
2004-01-01
William W. Cadbury M.D. was born in Philadelphia, USA and graduated from the Medical College of Pennsylvania University. It was nearly 40 years since he arrived in Canton (Guangzhou) in 1909 and left at retirement age. He taught western medicine in Canton Christian College and worked as a medical doctor in Canton Hospital, the oldest western medical hospital in the Orient. He was regarded as a famous foreign doctor and an excellent professor in internal medicine in the Republic of China. He wrote At the point of Lancet: 100 years of Canton Hospital 1835 - 1935, which recorded the achievement made by American missionary doctors, particularly the pioneers such as Peter Parker M.D. and John G. Kerr. M.D. So far the book is still an important reference for the studies on history of western medicine in China and the history of modern medical exchange between China and other countries.

Evaluation of sea otter capture after the Exxon Valdez oil spill, Prince William Sound, Alaska
Bodkin, James L.; Weltz, F.; Bayha, Keith; Kormendy, Jennifer
1990-01-01
After the T/V Exxon Valdez oil spill into Prince William Sound, the U.S. Fish and Wildlife Service and Exxon Company, U.S.A., began rescuing sea otters (Enhydra lutris). The primary objective of this operation was to capture live, oiled sea otters for cleaning and rehabilitation. Between 30 March and 29 May 1989, 139 live sea otters were captured in the sound and transported to rehabilitation centers in Valdez, Alaska. Within the first 15 days of capture operations, 122 (88%) otters were captured. Most sea otters were captured near Knight, Green, and Evans islands in the western sound. The primary capture method consisted of dipnetting otters out of water and off beaches. While capture rates declined over time, survival of captured otters increased as the interval from spill date to capture date increased. The relative degree of oiling observed for each otter captured declined over time. Declining capture rates led to the use of tangle nets. The evidence suggests the greatest threat to sea otters in Prince William Sound occurred within the first 3 weeks after the spill. Thus, in the future, the authors believe rescue efforts should begin as soon as possible after an oil spill in sea otter habitat. Further, preemptive capture and relocation of sea otters in Prince William Sound may have increased the number of otters that could have survived this event.

Full Text Available This article intends to investigate the doctor’s mind style on William Carlos Williams in his collection of poems Spring and All. Research shows that Williams’s doctor’s life makes him shape a different view of the world. He always observes something difficult or challenging at first and notices something easy and comfortable at last. This paper concludes that Williams’s doctor’s mind style exerts influence on his creation of poetry both in content and in form.

Charles William Lacaillade. Biologist, Parasitologist, Educator, and Mentor.
Imperato, Pascal James
2017-02-01
Charles William Lacaillade (1904-1978) was an eminent biologist in the middle decades of the twentieth century. He was born in Lawrence, Massachusetts of parents whose ancestors were French Canadians. His father, also named Charles William Lacaillade, was a dentist who graduated from Tufts University School of Dentistry in 1898. His mother, Elodia Eno, came from a family of very successful businessmen. Lacaillade was the third of six children. His two older brothers, Harold Carleton and Hector Eno, both graduated from the University of Louisville, School of Dentistry, while his younger brother, Lawrence, became a businessman. His sister, Luemma, married Dr. Henry Steadman, a veterinarian, while his youngest sister, Gloria, married a U.S. Army officer, Lieutenant Colonel Victor Anido. Lacaillade received his MS and PhD degrees in biology and zoology from Harvard University. He then became a fellow at The Rockefeller Institute for Medical Research. At both institutions, he studied under some of the most eminent biological scientists of the time. These included Rudolf W. Glaser, George Howard Parker, Theobald Smith, Carl TenBroeck, and William Morton Wheeler. At the Rockefeller Institute, he co-discovered the vector and mode of transmission of Eastern Equine Encephalomyelitis. This discovery, and the research he conducted with Rudolf W. Glaser, quickly established him as an outstanding biological researcher. However, a change in leadership at the Rockefeller Institute resulted in research priorities being given to the disciplines of general physiology, physical chemistry, and nutrition. This shift in the research agenda away from the biological sciences precluded career advancement at the Rockefeller Institute for post-doctoral fellows like Lacaillade. It was the height of the Great Depression, and even biologists with terminal doctoral degrees found it difficult to find positions. In 1935, Lacaillade accepted a position as an assistant in biology at St. John

Williams-Beuren syndrome is a rare neurodevelopmental disorder caused by deletion of 1.5-1.8Mb genes on chromosome 7q11.23. The syndrome was first described as a triad of supra-valvular aortic stenosis, mental retardation, and distinctive facial features. Our patient was referred due to audible inspiratory stridor when he was seven days old. Following endoscopy he was diagnosed with bilateral vocal cord paralysis and was eventually intubated due to respiratory de-compensation followed by tracheotomy. On further workup he was diagnosed with hypothyroidism. Genetic workup supported the diagnosis of Williams-Beuren syndrome. We report here a case with an unusual clinical presentation.

Full Text Available A 15-month-old male infant diagnosed with Williams Syndrome (WS was admitted with severe hypercalcemia and nephrocalcinosis. Intravenous hydration and furosemide failed to yield an appreciable and sustainable fall in serum calcium, while the injection of pamidronate achieved a significant decrease in serum calcium in a short period of time. This bisphosphonate could be considered as a second-line treatment for refractory hypercalcemia in WS.

This study describes the biological results of a comprehensive shoreline ecology program designed to assess ecological recovery in Prince William Sound following the Exxon Valdez oil spill on march 24, 1989. The program is an application of the ''Sediment Quality Triad'' approach, combining chemical, toxicological, and biological measurements. The study was designed so that results could be extrapolated to the entire spill zone in Prince William Sound. The spill affected four major shoreline habitat types in Prince William Sound: pebble/gravel, boulder/cobble, sheltered bedrock, and exposed bedrock. The study design had two components: (1) one-time stratified random sampling at 64 sites representing four habitats and four oiling levels (including unoiled reference sites) and (2) periodic sampling at 12 nonrandomly chosen sites that included some of the most heavily oiled locations in the sound. Biological communities on rock surfaces and in intertidal and shallow subtidal sediments were analyzed for differences resulting from to oiling in each of 16 habitat/tide zone combinations. Statistical methods included univariate analyses of individual species abundances and community parameter variables (total abundance, species richness, and Shannon diversity), and multivariate correspondence analysis of community structure. 58 refs., 13 figs., 9 tabs

The search for the origin of the commonly held principle in current neurosurgery regarding the resectability of the anterior one third of the superior sagittal sinus unravels the many fascinating developments that occurred in neurosurgery during the early 20th century. All these occurrences can be traced back to, and are uniquely contextualized in, Harvey Cushing's seminal text, Meningiomas, Their Classification, Regional Behaviour, Life History, and Surgical End Results. Written with Louise Eisenhardt and published in 1938, Meningiomas is a monograph of incredible description and detail. The meticulous categorization of meningiomas, their presentation, clinical outcome, and surgical therapies are even further supplemented by Cushing's personal commentary, questions, and recollections. Cushing's genius was evident in his ability not only to make insightful clinical observations, but also to synthesize these ideas within the neurosurgical context of his era. As he says in Meningiomas, "Thus the pathological curiosity of one day becomes in its proper time a commonplace... most of which are one and the same disorder--had, for their interpretation, to await the advent of the Neurosurgeon."

A report from America: Baby M.
Rachels, James
1987-10-01
Rachels reviews the social and legal facts of the celebrated "Baby M" case, in which surrogate Mary Beth Whitehead attempted to keep the daughter she had borne under contract to William Stern. The first phase of the legal battle between the parents ended in March 1988, when New Jersey Superior Court Judge Harvey R. Sorkow upheld the validity of the surrogacy contract, terminated Whitehead's parental rights, and awarded custody of the child to Stern. Rachels comments on public reaction to "Baby M," on Sorkow's decision, and on the impact the case may have on legislative attempts to regulate surrogacy. He also uses the example of "Baby M," as well as that of California heart transplant patient "Baby Jesse," to discuss how the media sensationalize controversial issues.

William Osler's "The Nervousness of American Women".
Golden, Richard L
2008-02-01
Almost a century ago, William Osler, the foremost physician of his time, was approached by a leading periodical to write a series of articles on the health of the American woman. Osler, then the Regius Professor of Medicine at Oxford, wrote an essay dealing with the psychological stresses affecting the "new woman" of the early 20th century at varying stages of her development and the "nervousness" that ensued. The article was never published as a result of his belated reservations on the propriety of a professional writing for a lay journal. Osler's thinking frequently reflected the spirit of his Victorian-Edwardian era, although at times he demonstrated advanced and prescient ideas about sexuality, not often the subject of discussion, even in circumspect form, in contemporary nonprofessional literature.

A Mystic in English Literature: William Blake
Directory of Open Access Journals (Sweden)
Ali Fahri DOĞAN
2015-12-01
Full Text Available Human beings have never been satisfied with this ephemeral world. Perhaps, yearning and desire of rejoining −stemming from the descent from the heaven to the earth− are the emotions felt by the members of both celestial and non-celestial religions. Mysticism, having started with the zeal of people who weren‘t satisfied with this ephemeral world towards the eternal world, aimed at the love of God in the religions where there is a belief of single God. In this article, glancing at the life of a Christian mystic William Blake, we will try to shed light into his mystic thoughts. While studying Blake‘s mystic thoughts, there will be common points with Sufism. Nevertheless, analysis of these common points has been assigned to other studies.

'O' Rose Thou Art Sick': Floral Symbolism in William Blake's Poetry
Directory of Open Access Journals (Sweden)
Noelia Malla
2014-04-01
Full Text Available The primary aim of this paper is to analyse the symbolic implications of floral imagery in William Blake’s poetry. More specifically, this study explores the process of floral (resignification of William Blake’s Songs of Innocence (1789 and Songs of Experience (1794 as case studies. Since “Without contraries [there] is no progression” (Marriage of Heaven and Hell, plate 3, it can be argued that the Songs represent contrary aspects of the human condition that far from contradicting each other, establish a static contrast of shifting tensions and revaluation of the flower-image not only as a perfect symbol of the “vegetable” life rooted to the Earth but also as a figure longing to be free. In some sense at some level, the poetic-prophetic voice asserts in the Songs of Experience the state of corruption where man has fallen into. Ultimately, this study will explore how the failure to overcome the contrast that is suggested in the Songs will be deepened by the tragedy of Thel, which is symbolized by all unborn forces of life, all sterile seeds as an ultimate means of metaphorical regeneration throughout Poetry which constitutes in itself the Poet Prophet’s own means of transcending through art.

Objective: To explore the clinical phenotypes and the genetic cause for a boy with unexplained growth retardation, nephrocalcinosis, auditory anomalies and multi-organ/system developmental disorders. Method: Routine G-banding and chromosome microarray analysis were applied to a child with unexplained growth retardation, nephrocalcinosis, auditory anomalies and multi-organ/system developmental disorders treated in the Department of Pediatrics of Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology in September 2015 and his parents to conduct the chromosomal karyotype analysis and the whole genome scanning. Deleted genes were searched in the Decipher and NCBI databases, and their relationships with the clinical phenotypes were analyzed. Result: A six-month-old boy was refered to us because of unexplained growth retardation and feeding intolerance.The affected child presented with abnormal manifestation such as special face, umbilical hernia, growth retardation, hypothyroidism, congenital heart disease, right ear sensorineural deafness, hypercalcemia and nephrocalcinosis. The child's karyotype was 46, XY, 16qh + , and his parents' karyotypes were normal. Chromosome microarray analysis revealed a 1 436 kb deletion on the 7q11.23(72701098_74136633) region of the child. This region included 23 protein-coding genes, which were reported to be corresponding to Williams-Beuren syndrome and its certain clinical phenotypes. His parents' results of chromosome microarray analysis were normal. Conclusion: A boy with characteristic manifestation of Williams-Beuren syndrome and rare nephrocalcinosis was diagnosed using chromosome microarray analysis. The deletion on the 7q11.23 might be related to the clinical phenotypes of Williams-Beuren syndrome, yet further studies are needed.

Hurricane Harvey inflicted historical catastrophic flooding across extensive regions around Houston and southeast Texas after making landfall on 25 August 2017. The Federal Emergency Management Agency (FEMA) requested urgent supports for flood mapping and monitoring in an emergency response to the extreme flood situation. An innovative satellite remote sensing method, called the Depolarization Reduction Algorithm for Global Observations of inundatioN (DRAGON), has been developed and implemented for use with Sentinel synthetic aperture radar (SAR) satellite data at a resolution of 10 meters to identify, map, and monitor inundation including pre-existing water bodies and newly flooded areas. Results from this new method are hydrologically consistent and have been verified with known surface waters (e.g., coastal ocean, rivers, lakes, reservoirs, etc.), with clear-sky high-resolution WorldView images (where waves can be seen on surface water in inundated areas within a small spatial coverage), and with other flood maps from the consortium of Global Flood Partnership derived from multiple satellite datasets (including clear-sky Landsat and MODIS at lower resolutions). Figure 1 is a high-resolution (4K UHD) image of a composite inundation map for the region around Rosharon (in Brazoria County, south of Houston, Texas). This composite inundation map reveals extensive flooding on 29 August 2017 (four days after Hurricane Harvey made landfall), and the inundation was still persistent in most of the west and south of Rosharon one week later (5 September 2017) while flooding was reduced in the east of Rosharon. Hurricane Irma brought flooding to a number of areas in Florida. As of 10 September 2017, Sentinel SAR flood maps reveal inundation in the Florida Panhandle and over lowland surfaces on several islands in the Florida Keys. However, Sentinel SAR results indicate that flooding along the Florida coast was not extreme despite Irma was a Category-5 hurricane that might

William Crabtree and the date of Easter
Sellers, D.
2014-04-01
A previously unknown treatise by William Crabtree (c.1603-c.1644) has recently been unearthed in the Lancashire Record Office. The treatise, in manuscript form and written in 1640, deals with the controversy over the long-term impact of the Julian Calendar - then in use in England - upon the ecclesiastical dating of Easter. By Crabtree's time, the timing of the Easter celebration in England was often several weeks adrift of the intentions of the early Church Fathers. The Gregorian Calendar, which Roman Catholic countries had adopted as long ago as 1582 in order to resolve the problem, was still vehemently resisted by the English state. This is possibly the only surviving manuscript in Crabtree's own hand. In it, he displays noteworthy dispassionate objectivity as he outlines the astronomical basis for the Easter date and explains why it has gone awry.

We report a 38-year-old patient who presented with pulmonary hypertension and right ventricular dysfunction due to pulmonary artery stenoses as a manifestation of Williams syndrome, mimicking chronic thromboembolic pulmonary hypertension. The patient was treated with balloon angioplasty and stent implantation. Short-term follow-up showed a good clinical result with excellent patency of the stents but early restenosis of the segments in which only balloon angioplasty was performed. These stenoses were subsequently also treated successfully by stent implantation. Stent patency was observed 3 years after the first procedure

Dr. William O. Coffee and his absorption cure for cataract.
Ferry, A P
1989-08-01
Dr. William O. Coffee was an ophthalmologist who conducted an office and mail-order practice in the Midwest from the 1880s until 1927. His main stock in trade was a self-discovered absorption cure for a variety of ocular diseases, with particular emphasis on the medical cure of cataracts. Dr. Coffee's career was a checkered one, marked by dubious credentials, exuberant self-promotion, unlikely and exaggerated claims of medical successes, plagiarism, and rejection by the medical "establishment." Certain parallels may be drawn between his activities and some currently observed practices in ophthalmology.

[Sir William Richard Gowers: author of the "bible of neurology"].
Hirose, Genjiro
2014-11-01
William Richard Gowers is one of the great pioneers in neurology and the author of the well-known neurology textbook, "A Manual of Diseases of the Nervous System." His concepts of neurology are based on meticulously and carefully accumulated knowledge of history, observations, and neurological examinations of patients with various neurological diseases. He is not only a great neurologist but also a great teacher who loves teaching students and physicians through well-prepared lectures. We can glean the essence of the field of neurology through his life story and numerous writings concerning neurological diseases.

A gestalt approach to the science fiction novels of William Gibson
McFarlane, Anna M.
2015-01-01
Gestalt psychologists Kurt Koffka and Wolfgang Köhler argue that human perception relies on a form, or gestalt, into which perceptions are assimilated. Gestalt theory has been applied to the visual arts by Rudolf Arnheim and to literature by Wolfgang Iser. My original contribution to knowledge is to use gestalt theory to perform literary criticism, an approach that highlights the importance of perception in William Gibson’s novels and the impact of this emphasis on posthumanism and science fi...

William Blake’s Milton a Poem as a conversion narrative in the Behmenist tradition
DEFF Research Database (Denmark)
Jessen, Elisabeth Engell
2014-01-01
The term ‘conversion narrative’ lacks proper definition and can be understood more broadly than is often the case, underlining its fictive nature. I show this by reading William Blake’s Milton a Poem as a conversion narrative, exploring how Blake weaves a wider discourse of conversion around...

Harvey Cushing: first guest at "The Divine Banquet of the Brayne".
Modlin, I M; Shin, J H
1993-04-01
Harvey Cushing will remain forever ensconced in surgical memory as the visionary who established contemporary neurosurgery. Raised in Cleveland in a middle-class family with a medical background, he gave little indication early of his later prowess. A college education at Yale University yielded a modest performance, although he showed somewhat better promise as a medical student at Harvard University. During his surgical training at the Johns Hopkins Medical School, he emerged as a bright, industrious young man with a glint of steel to his intellect. From Halsted he learned the academic basis of surgery and the meticulousness necessary for technical success. Osler became his friend and provided him with a foundation in the history of medicine and the recognition of its importance in shaping the future. The decision to spend a year in Europe visiting clinics and renowned surgeons may have laid the foundations for the subsequent configuration of his career. In Britain he saw firsthand the glorious museums and libraries of the Hunters and the legacy that their schools of surgery had endowed to the nation. In Paris and London he mixed with the surgical aristocracy of the times and learned the power of societies and the traditions of their patrons. In Berne he was exposed to the surgical purity and physiologic expertise of Kocher, supported by the estimable scientific practice of Kroneker. As an "arbeid," Kocher posed him the problem of establishing the mechanism of the regulation of cerebral perfusion. This question, which he so rapidly and successfully unraveled, probably played a large part in igniting his enthusiasm toward the study of the brain as a future career. In his travels he encountered diverse intellects and experienced a wide panoply of European medical thought. He conversed widely at both a social and professional level and integrated all information into meticulously kept diaries that served as not only a record but also a template from which later

Williams syndrome is an uncommon genetic disorder associated with supravalvular aortic stenosis (SVAS) in childhood. We reviewed outcomes of children with Williams syndrome who underwent repair of SVAS during a 30-year period at a single institution. Between 1982 and 2012, 28 patients with Williams syndrome were operated on for SVAS. Mean age at operation was 5.2 years (range, 3 months to 13 years), and mean weight at operation was 18.6 kg (range, 4.1 to 72.4 kg). Associated cardiac lesions in 11 patients (39.3%) were repaired at the time of the SVAS repair. The most common associated cardiac lesion was main pulmonary artery stenosis (8 of 28 [28%]). A 3-patch repair was performed in 10 patients, a Doty repair in 17, and a McGoon repair in 1 (3.6%). There were no early deaths. Follow-up was 96% complete (27 of 28). Overall mean follow-up was 11.2 years (range, 1 month to 27.3 years). Mean follow-up was 5 years (range, 1 month to 14.3 years) for the 3-patch repair patients and 14.7 years (range, 6 weeks to 27 years) for the Doty repair patients. Of the 17 Doty patients, there were 4 (24%) late deaths, occurring at 6 weeks, 3.5 years, 4 years, and 16 years after the initial operation. There were no late deaths in the 3-patch repair patients. Overall survival was 86% at 5, 10, and 15 years after repair. Survival was 82% at 5, 10 and 15 years for the Doty repair patients. Overall, 6 of 27 patients (22%) patients required late reoperation at a mean of 11.2 years (range, 3.6 to 23 years). No 3-patch repair patients required reoperation. Overall freedom from reoperation was 91% at 5 years and 73% at 10 and 15 years. Freedom from reoperation for the Doty repair patients was 93% at 5 years and 71% at 10 and 15 years. Surgical repair of SVAS in children Williams syndrome has excellent early results. However, significant late mortality and morbidity warrants close follow-up.

Syntax in Spanish-speaking children with Williams syndrome.
Benítez-Burraco, Antonio; Garayzábal, Elena; Cuetos, Fernando
2016-01-01
The syntactic skills of Spanish-speaking children with Williams syndrome (WS) were assessed in different areas (phrase structure, recursion, and bound anaphora). Children were compared to typically-developing peers matched either in chronological age (CA-TD) or in verbal age (VA-TD). In all tasks children with WS performed significantly worse than CA-TD children, but similarly to VA-TD children. However, significant differences were observed in specific domains, particularly regarding sentences with cross-serial dependencies. At the same time, children with WS were less sensitive to syntactic constraints and exhibited a poorer knowledge of some functional words (specifically, of nonreflexive pronouns). A processing bottleneck or a computational constraint may account for this outcome. Copyright © 2016 Elsevier Inc. All rights reserved.
