    Physician-to-physician consultation and discussion have traditionally been conducted by telephone, paper, and "curbside" (face to face meetings). The implementation and use of physician-to-physician consultation via electronic mail in a military health care system has not been reported previously. The group mail function of the Composite Health Care System, the main outpatient medical automation system for the Department of Defense, was modified to create mailgroups for every specialty of the Walter Reed Army Medical Center to facilitate ease of physician-to-physician consultation. This modification was called the "Ask a Doc" system. The system was deployed to a 21-state health care network among triservice participants. There were 3,121 consultations logged from April 22, 1998, to December 31, 2000. Growth in use expanded initially and was sustained during a 3-year period. Average response time to consultations was less than 1 day (11.93 hours). Additional training and maintenance requirements were minimal. In general, the use of electronic consultation mirrored that of clinical practice. Most specialty consultations involved the disciplines of internal medicine. Use of the Ask a Doc system was representative of total clinical workload and increased access to specialty medical care over a wide geographic area. The distribution of use indicated that user statistics were legitimate, and quality improvement programs could easily troubleshoot the system. Ask a Doc was inserted into a regional health care network with minimal cost to support and implement and was sustained with very little effort for 3 years. Barriers to even wider use currently include lack of secure communications and the difficulty in assigning workload credit for electronic consultations.

  6. Cell-mediated immunity to HIV-1 in Walter Reed stages 1-6 individuals: correlation with virus burden.

    Cell-mediated immunity (CMI) to human immunodeficiency virus-1 (HIV-1) was assessed in a blinded fashion for a patient group (n = 79) representing Walter Reed (WR) stages 1-6. At the same time, viral load was quantitatively measured by two different methods, specifically, virus isolation and HIV viral DNA copy number as measured by the polymerase chain reaction (PCR). After unblinding it was determined that the ability to generate a lymphoproliferative response to an inactivated gp120-depleted HIV (HIV-ag) and tetanus toxoid diminished with advancing WR staging, with complete anergy to HIV-ag and tetanus at stage 6. As a group, individuals whose peripheral blood mononuclear cells (PBMC) proliferated to HIV-ag were either virus isolation negative or produced low levels of virus as measured by p24 antigen (< 250 pg p24) on day 7. Similarly, HIV DNA copy number in the HIV-ag responders was low (< 200 copies/4 x 10(5) PBMC). In contrast, antigen proliferation to tetanus toxoid did not correlate with virus load. Thus, clinical progression as defined by the WR staging system appears to coincide with a loss of CMI to HIV. More importantly, the low viral load measured in HIV-ag responders suggests a link between viral burden and CMI to HIV which might be exploited in the design of immunotherapies for HIV-infected individuals.

  14. The human dengue challenge experience at the Walter Reed Army Institute of Research.

    2014-06-15

    Recent discordance between measured levels of serotypes of dengue virus neutralizing antibody and clinical outcomes suggests a need to reevaluate the process of prescreening dengue vaccine candidates to better predict their clinical benefit before initiation of large-scale human vaccine trials. In the absence of a reliable animal model for dengue, a human dengue virus challenge model (ie, a controlled live dengue virus infectious challenge study) may prove useful and timely to elucidate mechanisms that underlie protection (as well as virulence), thus facilitating down-selection of vaccine candidates before beginning advanced field trials. Dengue challenge studies were safely used in prior decades to study the vector biology, clinical spectrum of illness, and reactogenicity of candidate live dengue virus vaccines of uncertain attenuation. Redeveloping the human dengue challenge model following current regulatory guidance, good manufacturing practice, and good clinical practice could streamline and accelerate vaccine development by offering a time- and resource-efficient method to evaluate the safety and potential efficacy of dengue vaccine and therapeutic candidates. In this article, the development of such a challenge model and its subsequent application is summarized from 2 recent reports. Published by Oxford University Press on behalf of the Infectious Diseases Society of America 2014. This work is written by (a) US Government employee(s) and is in the public domain in the US.

    1954-01-01

    Walter C. Williams was Chief of the National Advisory Committee for Aeronautics' and the National Aeronautics and Space Administration's flight research organization on Edwards Air Force Base until his appointment as Associate Director of Project Mercury on September 15, 1959. Walt had started his career with NACA at Langley Memorial Aeronautical Laboratory in 1939 as an engineer in the Flight Division. In 1946 he transferred to the Muroc Army Air Field to be in charge of the small group of technicians and engineers who would be doing the flight research on a joint NACA-Army Air Forces program involving the rocket-powered Bell XS-1. See photo DIRECTORS E-49-0170, which addresses the first eight years of Walt's responsibilities with NACA. Williams' achievements as Chief of the NACA/NASA High-Speed Flight Station for the next five years continued to be significant. NACA pilot Joseph A. Walker made the first of 20 NACA research flights in the Douglas X-3 'Flying Stiletto'--on which inertial coupling was first experience--in 1954. The first NACA flight in an Lockheed F-104A aircraft occurred on August 27, 1956. On October 15, 1958, the first of three North American X-15 rocket research aircraft arrived at NASA High Speed Flight Station as preparations moved ahead for the highly successful NASA-Air Force-Navy-North American program that would last 10 years and investigate hypersonic flight. Walt directed a great variety of other flight research programs, including that on the Boeing B-47; investigations using the Century Series fighters, F-100, F-102, F-104, F-105 and F-107; and the ones involving the X-1 #2, which became the X1-E. During Williams' career, he twice received the NASA Distinguished Service Medal and was nominated both to the Meritorious Rank and Distinguished Rank in the Federal Senior Executive Service. In 1963 he was awarded an honorary doctorate of engineering degree by Louisiana State University. He received several awards from the American Institute

    Local characteristics of fabrics varied to suit special applications. Adjustable reed machinery proposed for use in weaving fabrics in various net shapes, widths, yarn spacings, and yarn angles. Locations of edges of fabric and configuration of warp and filling yarns varied along fabric to obtain specified properties. In machinery, reed wires mounted in groups on sliders, mounted on lengthwise rails in reed frame. Mechanisms incorporated to move sliders lengthwise, parallel to warp yarns, by sliding them along rails; move sliders crosswise by translating reed frame rails perpendicular to warp yarns; and crosswise by spreading reed rails within group. Profile of reed wires in group on each slider changed.

  7. Walter Garstang: a retrospective.

    Science.gov (United States)

    Holland, Nicholas D

    2011-12-01

    Although, Walter Garstang died over 60 years ago, his work is still cited--sometimes praised, but sometimes belittled. On the negative side, he often appropriated ideas of others without attribution, ignored earlier studies conflicting with his theories, and clung to notions like inheritance of acquired characters, progressive evolution, and saltation after many of his contemporaries were advancing toward the modern synthesis. Moreover, his evolutionary scenarios--especially his derivation of vertebrates from a sessile ascidian--have not been well supported by recent work in developmental genetics and molecular phylogenetics. On the positive side, Garstang firmly established several points of view that remain useful in the age of evolutionary development (evo-devo). He popularized the valid idea that adaptive changes in larvae combined with shifts in developmental timing (heterochrony) could radically change adult morphology and provide an escape from overspecialization. Moreover, his re-statement of the biogenetic law is now widely accepted: namely, that recapitulation results when characters at one stage of development are required for the correct formation of other characters at subsequent stages (his stepping stone model). In other words, ontogeny creates phylogeny because some developmental features are constraints, favoring particular evolutionary outcomes while excluding others. This viewpoint is a useful basis for advancing concepts of homology and for comparing the phylogeny of ontogenies across a series of animals to ascertain the timing and the nature of the underlying ontogenetic changes.

    2005-12-01

    Walter Alexander Feibelman, 79, an astronomer who discovered the E-ring of Saturn, died of a heart attack 19 November 2004 at his home at Riderwood Village in Silver Spring, Maryland. Walter was born 30 October 1925 in Berlin, Germany to Bernard and Dora Feibelman. He came to the United States with his parents in 1941. They were some of the last German Jews to flee Nazi Germany. Years later, he reported his experiences in an account contributed to the U.S. Holocaust Memorial Museum. As a youth, he worked at a cleaning shop and as a soda jerk before taking a course in tool and die making. He worked at the Abbey Photo Corp. in New York and in a model-making firm, where he constructed models of aircraft for use in identification courses by the Army Air Forces. After high school, he attended the Carnegie Institute of Technology and received his BS degree in 1956. Until 1969, he was a research scientist at the University of Pittsburgh. While working as an assistant research professor in physics and astronomy at the University of Pittsburgh in 1967, he examined a photo of Saturn taken a year earlier at the university's Allegheny Observatory. The E-ring -- unlike the bright main rings, A, B, C, D and F -- is faint and not easily spotted. He paired his observation with calculations and announced his discovery, which remained unconfirmed until the Pioneer 11 flyby in 1979. Walter joined the Optical Astronomy Division of Goddard Space Flight Center in Greenbelt in 1969, and worked there until 2002, when he became an emeritus astronomer at NASA. He became associated with the International Ultraviolet Explorer project, and worked on developing detectors for the orbiting observatory's spectrograph. The project turned out to be one of NASA's most successful observatories, operating from 1978 to 1996. In his scientific career, he published more than 200 refereed articles, mainly on hot stars and planetary nebulae. He also wrote papers in the fields of photography, spectroscopy

  10. Vibrational modes of the reed in a reed organ pipe

    Science.gov (United States)

    Huber, T. M.; Collins, B. A.; Pineda, M.; Hendrickson, C.

    2003-10-01

    We will describe a series of measurements of the vibrational modes of the reed in a reed organ pipe. These measurements were performed using a Polytec PSV-300 scanning vibrometer, which allows the vibrational deflection shape to be determined at any frequency. In addition to blowing the reed pipe in a standard fashion, a mechanical driver was used to excite the reed. Using both excitation sources, a number of deflection shapes were observed including simple cantilever, torsional, and higher-order shapes corresponding to higher-order cantilever and torsional modes. As expected, the observed frequencies of the mechanically driven modes were not integer multiples of the fundamental, and were consistent with theoretical predictions. The reed pipe was also excited in a standard manner using an organ blower. This raised integer multiples of the fundamental frequency as high as 20 kHz within two decades of the velocity amplitude of the fundamental. Torsional and other deflection shapes were present, however nonlinear interactions in the system caused them to be shifted from their mechanically driven frequencies. In some cases, significant vibration was observed in the tuning wire and the section of reed above the tuning wire that was previously considered to be clamped.

    Walter Meyerhof, one of the leading figures in the field of ion-atom collisions, passed away on May 27, 2006. He was 84 years old. He was born in Kiel, Germany, in the same year that his father, Otto Meyerhof, won the Nobel Prize in Medicine for his discovery of energetically important cycles in biological processes. Following his flight from Hitler-Germany in 1938, Walter Meyerhof studied from 1939-1940 at the Ecole de Physique et Chimie Industrielles in Paris, but when France too fell under Nazi occupation, he had to escape once again. In an exciting odyssey via Spain and Portugal he finally reached the United States. He received a doctorate degree in physics at the University of Pennsylvania in Philadelphia in 1946 with a thesis in solid-state physics. In the same year, he became Assistant Professor at the University of Illinois and in 1949 at Stanford University. In 1952 he was promoted to Associate Professor and in 1959 to Full Professor. From 1970 to 1977 he served as a Chairman of the Stanford Physics Department (see Fig. 1).

    2015-01-01

    Walter S. Sutton (1877-1916) was a physician, scientist, and inventor. Most of the work on Sutton has focused on his recognition that chromosomes carry genetic material and are the basis for Mendelian inheritance. Perhaps less well known is his work on rectal administration of ether. After Sutton's work on genetics, he completed his medical degree in 1907 and began a 2-year surgical fellowship at Roosevelt Hospital, New York City, NY, where he was introduced to the technique of rectal administration of ether. Sutton modified the work of others and documented 100 cases that were reported in his 1910 landmark paper "Anaesthesia by Colonic Absorption of Ether". Sutton had several deaths in his study, but he did not blame the rectal method. He felt that his use of rectal anesthesia was safe when administered appropriately and believed that it offered a distinct advantage over traditional pulmonary ether administration. His indications for its use included (1) head and neck surgery; (2) operations when ether absorption must be minimized due to heart, lung, or kidney problems; and (3) preoperative pulmonary complications. His contraindications included (1) cases involving alimentary tract or weakened colon; (2) laparotomies, except when the peritoneal cavity was not opened; (3) incompetent sphincter or anal fistula; (4) orthopnea; and (5) emergency cases. Sutton wrote the chapter on "Rectal Anesthesia" in one of the first comprehensive textbooks in anesthesia, James Tayloe Gwathmey's Anesthesia. Walter Sutton died of a ruptured appendix in 1916 at age 39.

    A CRDM (Control Rod Drive Mechanism) is an electromagnetic device which drives a control rod assembly linearly to regulate the reactivity of a nuclear core. A RPIS (Rod Position Indication System) is used as a position indicator of a control rod assembly for a CRDM of a nuclear reactor, SMART. A highly accurate RPIS for SMART is required because the reactivity of a nuclear core for a small modular reactor is more sensitive than the commercial ones. In this study, the effect of positioning direction of the reeds in a reed switch for the CRDM RPIS has been studied using the electromagnetic FE analysis. It is found that the positioning direction of the reeds slightly but not significantly affects the formation of attraction. Analysis results will be used as the basis on estimated accuracy of full RPIS system.

    The complexity of decoding the standard Reed-Solomon code is a well-known open problem in coding theory. The main problem is to compute the error distance of a received word.Using the Weil bound for character sum estimate,Li and Wan showed that the error distance can be determined when the degree of the received word as a polynomial is small.In the first part,the result of Li and Wan is improved.On the other hand,one of the important parameters of an error-correcting code is the dimension.In most cases,one can only get bounds for the dinension.In the second part,a formula for the dimension of the generalized trace Reed-Solonon codes in some cases is obtained.

  7. Reed's Conjecture on hole expansions

    CERN Document Server

    Fouquet, Jean-Luc

    2012-01-01

    In 1998, Reed conjectured that for any graph $G$, $\\chi(G) \\leq \\lceil \\frac{\\omega(G) + \\Delta(G)+1}{2}\\rceil$, where $\\chi(G)$, $\\omega(G)$, and $\\Delta(G)$ respectively denote the chromatic number, the clique number and the maximum degree of $G$. In this paper, we study this conjecture for some {\\em expansions} of graphs, that is graphs obtained with the well known operation {\\em composition} of graphs. We prove that Reed's Conjecture holds for expansions of bipartite graphs, for expansions of odd holes where the minimum chromatic number of the components is even, when some component of the expansion has chromatic number 1 or when a component induces a bipartite graph. Moreover, Reed's Conjecture holds if all components have the same chromatic number, if the components have chromatic number at most 4 and when the odd hole has length 5. Finally, when $G$ is an odd hole expansion, we prove $\\chi(G)\\leq\\lceil\\frac{\\omega(G)+\\Delta(G)+1}{2}\\rceil+1$.

    1995-01-01

    An apparatus and method for forming woven fabrics through the use of an adjustable reed. The adjustable reed has multiple groups of reed wires that guide the warp yarns. The groups of reed wires move on reed rails parallel to the warp direction. In addition, rail expanders permit the space between the reed wires to be modified and telescoping rods attached to the rail sliders can be turned to permit the reed wires to be skewed to alter the fill yarn angle. These adjustments to the reed permit simultaneous variation of fill yarn angles and fabric widths and allow these variations to be made during fabrication, without the need to halt production.

    Walter Bouldin is one of several hydroelectric developments of Alabama Power Company. On February 10, 1975, an earth embankment section of Walter Bouldin Dam was breached, causing total evacuation of the forebay reservoir and rendering the 225-MW power plant inoperable. The Federal Power Commission instituted an investigation of the dam failure, and a report on the investigation was published in February 1976. Subsequently, an evidentiary hearing was held before an administrative law judge who issued his initial decision on August 19, 1976. The Commission, on April 21, 1977, issued its Opinion No. 795 in which it adopted the initial decision with modifications and terminated the investigation of failure of Walter Bouldin Dam. Opinion No. 795 directs the staff of the Bureau of Power to prepare, for the future guidance of the Commission, a report on the deficiencies which were found in its investigation, together with advice as to how such deficiencies have been and should be remedied. Also, it directs the staff of the Bureau of Power to address certain general recommendations included in the initial decision. This report was prepared in response to that directive and summaries information on the dam failure and its investigation; the evidentiary hearing; the judge's recommendations, the reconstruction of the Bouldin Dam; and the evalution and status of the Federal Energy Regulatory Commission Dam safety program.

  1. The impacts of Walter Isard on geography

    Science.gov (United States)

    Jackson, Randall W.

    In the course of preparing this paper, which initially focused solely on identifying the impacts of input-output analysis on geography, a much broader perspective on the impacts of Walter Isard on geography ultimately emerged. In the tradition of input-output analysis, these impacts are grouped into direct, indirect, and induced effects, and summarized under the heading of influence. Walter Isard touched the lives of many through personal relationships, books and articles, and an energetic devotion to and enthusiasm for the creation of a regional science association. The Regional Science Association and its publications supported something of a greenhouse environment in which the seedlings of GIS and scientific geography could take root, until they were well enough established to enter mainstream geography. While clearly not limited to geography, the fruits of Walter Isard's labors continue to populate the discipline through his contemporaries, their students, students' students, and so on. The formative years of both regional science and scientific geography left an indelible mark on the nature of geographic inquiry.

    Reed Solomon codes are powerful error correcting codes that include some of the best random and burst correcting codes currently known. It is well known that an (n,k) Reed Solomon code can correct up to (n - k)/2 errors. Many applications utilizing Reed Solomon codes require corrections of errors consisting primarily of bursts. In this paper, it is shown that the burst correcting ability of Reed Solomon codes can be increased beyond (n - k)/2 with an acceptable probability of miscorrect.

    2011-01-01

    We consider weighted Reed-Muller codes over point ensemble $S_1 \\times...\\times S_m$ where $S_i$ needs not be of the same size as $S_j$. For $m = 2$ we determine optimal weights and analyze in detail what is the impact of the ratio $|S_1|/|S_2|$ on the minimum distance. In conclusion the weighted Reed-Muller code construction is much better than its reputation. For a class of affine variety codes that contains the weighted Reed-Muller codes we then present two list decoding algorithms. With a small modification one of these algorithms is able to correct up to 31 errors of the [49, 11, 28] Joyner code.

    Steve Reed believes the organization he has founded has the potential to radically increase the developing world's access to vaccines for neglected diseases. The efforts of the Seattle-based Infectious Disease Research Institute (IDRI), which operates as a not-for-profit biotech company, may start to pay off during the H1N1 'swine' flu pandemic. IDRI developed an adjuvant to boost the effectiveness and supplies of flu vaccines and is making the technology available to vaccine manufacturers in developing nations. Charlotte Schubert talks to Reed about how IDRI, a 90-person operation with a $19 million annual budget, could have such a big impact.

    The well known Plotkin construction is, in the current paper, generalized and used to yield new families of Z2Z4-additive codes, whose length, dimension as well as minimum distance are studied. These new constructions enable us to obtain families of Z2Z4-additive codes such that, under the Gray map, the corresponding binary codes have the same parameters and properties as the usual binary linear Reed-Muller codes. Moreover, the first family is the usual binary linear Reed-Muller family.

    WALTER R. COURTENAY, JR., ichthyologist and retired professor, Florida Atlantic University, Boca Raton, Florida, died in Gainesville, Florida, on 30 January 2014 at age 80. Walt was born in Neenah, Wisconsin, on 6 November 1933, son of Walter and Emily Courtenay. Walt's interest in fish began at a young age as evidenced by a childhood diary in which at 13 years of age he wrote about his first catch—a two-and-a-half pound “pike” from Lake Winnebago. When Walt turned ten, the family moved from Wisconsin to Nashville, Tennessee, the move precipitated by his father accepting a position as pastor of the First Presbyterian Church. During those early days in Nashville, Walt's father would take summers off and travel to Michigan to teach at Camp Miniwanca along the shore of Lake Michigan where father and son honed their angling skills. It was also at that time Walt's father had definite views on what his son should be doing in adult life—in Walt's case it was to become a medical doctor. However, his Woods Hole internship in marine biology and oceanography toward the end of his undergraduate years was a transformative experience for him so much so that he abandoned all ideas of becoming a medical doctor and instead specialized in ichthyology and oceanography. Apart from the inherent interest and opportunities Woods Hole opened to him, being back at the shore of a large body of water, in this case the Atlantic Ocean, was far more interesting than sitting in lectures on organic chemistry. With that, Walt completed his B.A. degree at Vanderbilt University in 1956. In 1960 while in graduate school in Miami, Walt met and married Francine Saporito, and over the next several years had two children, Walter III and Catherine. He went on to receive his M.S. in 1961 from The Rosenstiel School of Marine and Atmospheric Science at the University of Miami on the systematics of the genus Haemulon (grunts) and his Ph.D. degree in 1965 working under his advisor C.

    For the generation of sound, some woodwind musical instruments, e.g. oboe, bassoon, clarinet and saxophone, are provided with mouthpieces made from reeds. These reeds are the culms of Arundo donax, a tall, cane-like perennial grass. A general problem is that the material is of varying quality, yet externally differences cannot be observed. Hence, large proportions of the prepared reeds are unusable. One hypothesis is that the changes in quality are correlated with differences in the chemical and anatomical structure of the tissue. Therefore, a comparison of superior and inferior mouthpieces, used by professional musicians, was undertaken to determinate potential indicators of quality. Nuclear microprobe analysis of reeds was carried out and complemented by scanning electron and light microscopy. The elemental levels of Si, P, S, Cl, K and Ca were compared between good and poor mouthpieces using appropriate statistical tests. No statistically significant differences could be identified. Microscopical observations showed that partial occlusion of vessels by tylose formation was associated with material deemed unusable.

What if he was working on a sequel to his Arcades Project, translating his ideas about Paris, capital of the nineteenth century, to his new city and own epoch? And what if I inadvertently discovered the manuscript of this so-called Manhattan Project, and decided to write a study dedicated to the unearthed text? This paper offers a few reflections on, and quotations from, the book that I am currently, truly working on, which is an analysis of a phantom of a book, inspired by a real collection of reflections and quotations that were made in preparation for another book that was also never written.

    Full Text Available Reed-Muller codes play an important role in communication. In communication, security and error free data transmission are two major problems. In this paper, we propose a eight bit original data is encoded using distinct Reed-Muller techniques such as positive polarity Reed-Muller(PPRM, negative polarity Reed-Muller(NPRM, fixed polarity Reed-Muller(FPRM for secure data communication and also we can compare these techniques in terms of cost. The eight bit encoded data which is obtains from these Reed-Muller techniques are encoded again using hamming code for error free communication. It is found that among all these techniques fixed polarity Reed-Muller is the best technique which gives less cost .We can also observes that secure and error free communication is possible between transmitter and receiver. The data encryption and decryption process has been simulated using Isim simulator and the code is written in Verilog HDL.

    Institute of Scientific and Technical Information of China (English)

    1999-01-01

    The researches about reed growth were mainly concentrated on seasonal dynamics, investigation of reed resource, and comparison of different ecotypes of reed. By means of fractal geometric theory of non-linear science, the fractal character of growth pattern of reed, for the purpose of quantitatively exploring the mechanism of reed growth was studied. The way to calculate fractal dimension of reed growth is box-dimension (BD) and information dimension (ID). The results shown that the difference between two samplings in May and those among three samplings in June and later were not remarkable for both BD or ID. It was noted that the difference between samplings in and after May is significant. It was demonstrated that the fractal dimension of size distribution of reed ranged from 0.6235 to 0.8761. The distribution pattern could be statistically divided as two significant periods:the size of reed is quite well-distributed at the beginning of reed growth (fractal dimension > 0.8), but is irregular in the middle and later growth season (fractal dimension < 0.7). These results are benefit to reach the goal of rational use of reed resources and to protect the biodiversity in wetland ecosystem.

  6. Holographic Visualization of Vibration in a Moist Clarinet Reed

    2005-03-01

    We have extended the work of Pinard et al (J. Acoust. Soc .Am. 113, 1376 (2003)) [see also Facchinetti et al (ibid, p. 2874)] on dry clarinet reeds to permit the modes of moisture-saturated reeds to be visualized. By means of an artificial embouchure, nitrogen gas at 96% relative humidity was passed into a clarinet whose reed was normally attached at the ligature, but free of other constraint. An image of the reed was focused upon a CCD upon which was incident also a collimated reference wave. Just beyond the clarinet's bell was a loudspeaker which excited the clarinet's air column and reed into vibration. The reed's motion could be analyzed from the fringes visible in single-exposure, time-averaged interferograms. When dry, our reeds exhibited low compliance except in the vicinity of sharp resonances whose frequencies, extending upwards from ca. 2.2 kHz , all lay above the fundamentals of the clarinet's musical voice. By contrast, moist reeds were easily excited at any frequency within our clarinet's playing range, which extended downward to D3 at 147 Hz. At almost any frequency, the vibrations of the moist reed were strong mixtures of the flexing and torsional modes exhibited separately in the resonances of the dry reed.

The model, developed by the National Renewable Energy Laboratory's Strategic Energy Analysis Center, is designed to analyze the critical energy issues in the electric sector, especially with respect to potential energy policies, such as clean energy and renewable energy standards or carbon restrictions. ReEDS provides a detailed treatment of electricity-generating and electrical storage technologies and specifically addresses a variety of issues related to renewable energy technologies, including accessibility and cost of transmission, regional quality of renewable resources, seasonal and diurnal generation profiles, variability of wind and solar power, and the influence of variability on the reliability of the electrical grid. ReEDS addresses these issues through a highly discretized regional structure, explicit statistical treatment of the variability in wind and solar output over time, and consideration of ancillary services' requirements and costs.

    The Soda-AQ pulps were made from reed pretreated by white rot fungi Panus conchatus,Cyathus stercoreus and Pleurotus florida respectively. It was found that kappa number decreased and the brightness increased for Soda-AQ pulps from the reed treated by Pleurotus florida and Panus conchatus, but it was reverse for the pulp from reed treated by Cyathus stercoreus. The result indicated that white rot fungi Pleurotus florida and Panus conchatus were selective to degrade lignin in reed, which were good for biopulping, but Cyathus stercoreus was preferential to degrade cellulose,which was not good for biopulping.

    Full Text Available O artigo examina a interpretação feita por Walter Benjamin dos poemas de Charles Baudelaire marcados pela noção de ideal, a qual se opõe ao spleen. Benjamin encontra aí o esforço de rememoração de uma experiência plena, a qual constituiria, por sua vez, um elemento essencial à compreensão da modernidade como impossibilidade desta forma de experiência. Com as noções de beleza e de aura, o artigo busca ainda salientar a importância da categoria da distância para a configuração desta forma de experiência.This paper examines the interpretation made by Walter Benjamin of Baudelaire's poems determined by the notion of Ideal, which is opposed to the concept of spleen. The Ideal is identified by Benjamin as the effort of remembrance of a full experience, which constitutes an essential element to the understanding of modernity as the impossibility of such kind of experience. At last the explanation of the concepts of beauty and aura is introduced to emphasize the importance of the category of distance to the configuration of this form of experience.

    Walter Baade discovered the two stellar populations with the 100-in Mount Wilson reflector during World War II, but applied, tested, and extended this concept with the 200-in Hale telescope after it went into operation on Palomar Mountain in 1949. But he had begun observing there with the 18-in Schmidt telescope in 1937, soon after it was completed. Baade used panchromatic films and deep red filters in an attempt to penetrate the heavy interstellar extinction toward the Galactic center. The extinction was much too heavy for him to observe the center, but he found the least obscured regions in this survey, including "Baade's window," and several highly obscured globular clusters. The 48-in Schmidt was completed in 1948, and Baade was one of the very few observers allowed to use it briefly, before all the observing time was turned over to the National Geographic-Palomar Observatory Sky Survey. Again, he concentrated on seeking the "clearest" regions near the Galactic center, and also obtained some pictorial photographs of nebulae to publicize the success of the new instrument. Especially after Edwin Hubble's first heart attack in 1949, Baade took most of the final test exposures which Ira Bowen used to analyze and tune up the shape of the 200-in mirror. After the Hale telescope was in full operation, Baade had the lion's share of observing time with it. He had been aching to use it to search for RR Lyrae variables in M 31 it, and not finding any confirmed Baade's well grounded conjecture that the distance scale in use then was wrong. His work on variable stars in M 31, on the polarization of the continuum of the Crab nebula, and with Rudolph Minkowski on the optical identification of radio sources are a few examples of what he did with it. These and several other programs will be described, along with some of Baade's other activities at Palomar.

    Full Text Available The results on the selected biometric and mechanical properties of common reed Phragmites australis and reed sweet grass Glyceria maxima were presented. The experiments were conducted with the help of the universal testing machine Instron 5966. The underground biomasses, diameters, tensile forces, displacements and tensile strengths for summer and winter rhizomes of both species were assessed and compared. The final results indicate that rhizomes of common reed had higher values of the studied parameters of biometric and stretching than sweet reed grass rhizomes. Therefore, there are more opportunities to use them to protect the coastline.

    SANTHI, NANDAKISHORE [Los Alamos National Laboratory

    We consider a list decoding algorithm recently proposed by Pellikaan-Wu for q-ary Reed-Muller codes RM{sub q}({ell}, m, n) of length n {le} q{sup m} when {ell} {le} q. A simple and easily accessible correctness proof is given which shows that this algorithm achieves a relative error-correction radius of {tau} {le} (1-{radical}{ell}q{sup m-1}/n). This is an improvement over the proof using one-point Algebraic-Geometric decoding method given in. The described algorithm can be adapted to decode product Reed-Solomon codes. We then propose a new low complexity recursive aJgebraic decoding algorithm for product Reed-Solomon codes and Reed-Muller codes. This algorithm achieves a relative error correction radius of {tau} {le} {Pi}{sub i=1}{sup m} (1 - {radical}k{sub i}/q). This algorithm is then proved to outperform the Pellikaan-Wu algorithm in both complexity and error correction radius over a wide range of code rates.

  8. Reed as a gasification fuel: a comparison with woody fuels

    Directory of Open Access Journals (Sweden)

    S. Link

    2013-10-01

    Full Text Available Reed and coniferous wood can be used for energy production via thermochemical conversion, for instance by gasification. The rate-determining step of the gasification process is the reaction between the char and the gaseous environment in the gasifier, whose rate depends on variables such as pressure, temperature, particle size, mineral matter content, porosity, etc. It is known that reactivity can be improved by increasing the temperature, but on the other hand the temperature achieved in the reactor is limited due to the ash fusion characteristics. Usually, the availability of reed as a fuel is locally modest and, therefore, it must be blended with other fuels such as wood. Blending of fuels brings together several problems relating to ash behaviour, i.e. ash fusion issues. Because there is no correlation between the ash fusion characteristics of biomass blends and their individual components, it is essential to carry out prior laboratory-scale ash fusion tests on the blends. This study compares the reactivity of reed and coniferous wood, and the ash fusion characteristics of blends of reed and coniferous wood ashes. When compared with Douglas fir and reed chars, pine pellets have the highest reactivity. Reed char exhibits the lowest reactivity and, therefore, it is advantageous to gasify reed alone at higher gasification temperatures because the ash fusion temperatures of reed are higher than those of woody fuels. The ash produced by reed and wood blends can melt at lower temperatures than ash from both reed and wood gasified separately. Due to this circumstance the gasification temperature should be chosen carefully when gasification of blends is carried out.

  10. Feathering collisions in beating reed simulation

    Smyth, Tamara; Abel, Jonathan S.; Smith, Julius O.

    2003-10-01

    Pressure controlled valves are the primary sound production mechanisms for woodwind and brass musical instruments, as well as for many bioacoustic vocal systems such as the larynx and syrinx (the vocal organ in birds). During sound production, air flow sets a reed or membrane into motion creating a variable height in the valve channel and, potentially, periodically closing the channel completely. Depending on how this event is handled, an abrupt termination of air flow between open and closed states can cause undesirable discontinuities and inaccuracies in a discrete-time simulation-particularly at relatively low audio sampling rates. A solution was developed by re-examining the behavior of the differential equation governing volume flow through a pressure-controlled valve, paying particular attention to this rather troublesome transition. A closed-form solution for the time evolution of volume flow is given and used to derive an update for volume flow. The result is a smoother, more accurate, and nearly alias-free transition from open to closed. ``Feathered collisions'' of this nature can refine the sound quality produced by the numerical simulation of beating reeds, such as in clarinets, at typical audio sampling rates.

    Hilgeman, Theodore

    2009-01-01

    Walter G. Egan, a scientist and engineer with a professional life spanning well over half a century, died on 3 November 2003. Born to Caroline and George Egan on 12 October 1923 in New York City, Egan studied Electrical Engineering at the City College of New York from 1941 until 1943 when he was called to active duty in World War II, switching from enlisted reserve status. During the war, he served honorably in both the Signal Corps and the Medical Corps. Following his discharge in 1946, he resumed his college studies, obtaining a BEE in 1949 from City College of New York, an MA in Physics in 1951 from Columbia University, and a PhD in Solid State Physics in 1960 from the Polytechnic Institute of Brooklyn. Egan's PhD thesis was "Ferromagnetic Resonance in thin Nickel Films," performed under advisor H. Juretschke. Egan's professional career covered both industry and academia. In the summer of 1942, he worked for the Bruce Engineering Company. From 1957 to 1963, he worked for Ford Instrument Company, a Division of Sperry Rand Corporation, successively as an Engineering Project Supervisor, Assistant Director of Research, and Executive Assistant to the Director of Research. From 1964 to 1986 Egan worked as a Staff Scientist at the Grumman Corporation Corporate Research Center where his pioneering work consisted of research and development of remote sensing equipment and techniques for the remote sensing of terrestrial and space targets and backgrounds. I came to know and work with him during his tenure at the Grumman Corporation, where we co-authored many papers and a book. His insight into remote sensing engineering and research, shared willingly with younger colleagues, was a major stimulus to my future research in this field. Egan instilled a sense of discipline in publication, so our work could be shared with others in a timely way. This drive to share his knowledge with others also made him an excellent teacher. Subsequently, he held the position of Research

    Pinard, Fabrice; Laine, Benoit; Vach, Holger

    2003-03-01

    Vibrational modes of 24 clarinet reeds have been observed in both dry and wet conditions using holographic interferometry. Results have been compared with the ``musical quality'' of the reeds as judged by two professional clarinet players. An excellent correspondence has been demonstrated between specific vibrational behavior and musical quality. The results suggest that the presence and symmetry of a strong first torsional mode are indicative of good or very good musical quality. A second, but less stringent quality criterion is the proximity of frequencies corresponding to the second torsional and the second flexural mode. This proximity leads to the creation of mixed vibrational modes for the very best of the investigated clarinet reeds.

    We consider the problem of testing if a given function $f : \\F_2^n \\to \\F_2$ is close to any degree $d$ polynomial in $n$ variables, also known as the Reed-Muller testing problem. Alon et al. \\cite{AKKLR} proposed and analyzed a natural $2^{d+1}$-query test for this property and showed that it accepts every degree $d$ polynomial with probability 1, while rejecting functions that are $\\Omega(1)$-far with probability $\\Omega(1/(d 2^{d}))$. We give an asymptotically optimal analysis of their test showing that it rejects functions that are (even only) $\\Omega(2^{-d})$-far with $\\Omega(1)$-probability (so the rejection probability is a universal constant independent of $d$ and $n$). Our proof works by induction on $n$, and yields a new analysis of even the classical Blum-Luby-Rubinfeld \\cite{BLR} linearity test, for the setting of functions mapping $\\F_2^n$ to $\\F_2$. The optimality follows from a tighter analysis of counterexamples to the "inverse conjecture for the Gowers norm" constructed by \\cite{GT,LMS}. Our ...

  18. Upgraded fuel from reed canary grass

    Energy Technology Data Exchange (ETDEWEB)

    Heiskanen, V.P.

    1995-12-31

    The feasibility of RCG for commercial utilization depends primarily on its applicability for pulp production and its use in energy production will be based on the residue that will be available after extracting the pulp fraction of the RCG. Roughly 20 ..30% of the material will be available for energy production purposes. However, the percentage may be higher/lower depending on the quality standards of the pulp fiber material. The harvesting period has a significant effect on the fuel characteristics of RCG. For instance the contents of N, S, Cl, K are clearly lower if the RCG is harvested in the spring (delayed) instead of summer/autumn. These elements affect significantly overall emission formation and ash behaviour and its melting temperature. The combustion related research in this project has been focused on the spring-harvested RCG. The project aims to evaluate the feasibility of delayed harvested RCG for energy production. In order to reach this goal, the following combustion methods will be tested and studied: combustion of pelletized RCG; gasification; combustion of pulverized RCG. In addition, pelletizing, reactivity and NO conversion of pulverized RCG will be studied. The research described here is a part of `Reed Canary Grass` project (in AIR programme). The contractors of the project are Swedish University of Agricultural Sciences (coordinator), United Milling Systems from Denmark, Jaakko Poeyry Oy and VTT Energy. In addition, there are partners from several countries participating in the project. The project has been divided in five tasks, VTT Energy being responsible for combustion related task `Upgraded fuel` that includes the research topics discussed in this paper

The systems utilizes the composition of substances in reject water from reed-beds and that of sludge to reduce substance mass from...... within the container. The solution is then applied to the reed-beds, which dewaters, converts, and partially mineralize the sludge mixture. The reject water from the reed-beds is split where up to100% of the reject water is recirculated back to the mixed reactor and the remaining usually disposed...... the reject water via recirculation into a mixed reactor and back onto the reed-beds. The mixed rector consists of a container in which sludge (that is typically loaded directly on to reed-beds) is mixed with recirculated reject water from reed-beds. The sludge mixture has a definable hydraulic retention time...

    Gomez-Gelvez, Juan C; Smith, Lauren B

    2015-10-01

    Large atypical cells with morphologic and immunophenotypic features resembling Reed-Sternberg cells can be seen in the background of reactive lymphadenopathies as well as non-Hodgkin lymphomas. The presence of these cells is an important diagnostic pitfall that must be recognized by pathologists who regularly interpret lymph node biopsies. A thorough evaluation of the morphologic and immunophenotypic features of these cells and the cellular milieu is crucial in achieving the correct diagnosis. In this review, examples of lymphomas presenting with Reed-Sternberg-like cells will be provided. Additionally, a detailed description of the common morphologic and immunophenotypic features of these cells, as well as strategies that can be used to distinguish them from the Reed-Sternberg cells of classical Hodgkin lymphoma, will be emphasized.

  11. Transportation geography: The influence of Walter Isard and regional science

    Science.gov (United States)

    Chang, Stephanie E.

    . This paper explores the influence of Walter Isard, his work, and the field of regional science generally on transportation geography. It argues that Isard's impact was both subtle and significant. Regional science greatly influenced the emergence of modern transportation geography in the 1950s. Transportation themes and methods from Isard's own work provided early building blocks for transportation geography. Moreover, Isard and regional science contributed importantly to the development of the intellectual network of persons, places, and institutions that early on defined the subfield. Regional science and transportation geography have diverged in recent decades, but opportunities exist for renewed interaction.

  12. Impact of harvesting and fire on Phragmites australis reed quality in Tembe Elephant Park, Maputaland

    Directory of Open Access Journals (Sweden)

    M.W. van Rooyen

    2004-12-01

    Full Text Available In Maputaland, South Africa, the common reed (Phragmites australis is used extensively for hut building, fencing, craftwork and thatching. As a result of over-harvestingmost reed beds in communal areas have been degraded and are no longer producing reeds of the desired quality. At present the most productive reed beds are all found inconservation areas. The KwaMsomi area of the Muzi Swamp in the Tembe Elephant Park has been allocated to the Sibonisweni community for harvesting purposes. Thiscommunity has recently requested Ezemvelo KwaZulu-Natal Wildlife for additional areas for harvesting on the grounds that the current site was no longer yielding reeds of suitable quality. The main objective of this study was therefore to determine whether there was a decline in reed quality in the KwaMsomi harvested area. The results of thisstudy suggest that harvested areas contained more thin, short reeds than unharvested areas. Fire can be used to increase reed diameter in harvested areas, but will not significantly affect reed height. Ideally, reeds should only be harvested after the active growth period, when most of the nutrient reserves have been translocated to the rhizomes andthe buds are still dormant. To improve reed quality a three-year rotational harvesting programme should be implemented to allow the reeds to recover fully before being harvested again.

    1997-06-01

    Full Text Available Several authors in the 17th century used the atomic hypothesis to explain observable phenomena. This paper analyzes some ideas about chemical transformation proposed by the English physician Walter Charleton. In Physiologia Epicuro-Gassendo-Charltoniana (London, 1654, Charleton examined philosophical aspects of the atomic theory, and suggested that the best explanation for all natural phenomena would be only in terms of atoms and their motions. Sometimes, however, he had to attribute to the atoms some kind of "internal virtue", to explain more complex properties of the matter. His idea of "element", and the little use of experimentation and quantification, also limited the range of Charleton's theory.

    Full Text Available Walter Moers é um dos grandes autores da vertente fantástica dentro da literatura alemã atual. Desde a publicação de seu primeiro romance, em 1999, o escritor consagrou-se como autor de best-sellers. Nos seis romances publicados até a presente data tem-se um elemento comum, que serve de fio condutor às obras: o continente fictício de "Zamonien", um mundo maravilhoso criado por Moers. Esse mundo inventado é palco para inúmeras aventuras, lutas, jornadas, conquistas, mistérios, disputas, perigos, criaturas inusitadas e cenários desconhecidos. Se, por um lado, as obras fantásticas de Moers estão de acordo com as convenções do gênero da Fantasy; por outro, elas trazem consigo uma proposta literária inovadora, que rompe com algumas convenções desse gênero. É o caso da metaficcionalidade, presente de forma marcante em seus romances. Pretende-se nesse trabalho apresentar brevemente um romance de Walter Moers, Die Stadt der träumenden Bücher (2004, discorrer sobre os elementos constitutivos que inserem a obra no gênero da Fantasy e, por fim, aprofundar-se nos aspectos da metaficcionalidade encontrados na obra em questão.

    We make a brief survey on low weight codewords of generalized Reed-Muller codes and projective generalized Reed-Muller codes. In the affine case we give some information about the words that reach the second distance in cases where these words are not all characterized. Moreover we give the second weight of the projective Reed-Muller codes which was unknown until now. We relate the words of the projective Reed-Muller code reaching the second distance to the words of the affine Reed-Muller code reaching the second distance.

  2. Linear and nonlinear behavior of human and artificial lip reeds

    Science.gov (United States)

    Campbell, Murray; Richards, Orlando

    2003-10-01

    In a musical instrument of the lip reed aerophone class, the flow of air from the player's lungs into the resonating air column is modulated by the periodic opening and closing of the pressure-controlled valve formed by the player's lips. The nature of the operation of this valve has been the subject of considerable study in recent years. Since the pressure-flow relationship is strongly nonlinear, the behavior of the coupled system of lips and air column can only be modeled using the methods of nonlinear dynamics. Extensive studies of artificial lip reeds, in which the lips are simulated by water-filled latex tubes, have shown them to be capable of reproducing musically important features of human playing, including the lipping of notes both below and above an acoustic resonance of the air column. Measurements of the linear response of artificial reeds have guided the development of more realistic models of the lip reed, while studies of both real and artificial lips using a high-speed digital camera have shed fresh light on the nature of the lip motion at the large amplitudes typical of loud playing.

    2016-04-01

    Composition and ensilage performance of giant reed harvested in August, October, November, and December, were evaluated and compared. Generally, late-harvested giant reed had higher dry matter content, lower nitrogen content, and higher water soluble carbohydrates (WSC) content than early-harvested giant reed. During 90days of ensilage, giant reed harvested in October, November, and December showed dry matter losses of about 1%, while giant reed harvested in August showed a higher dry matter loss of about 8%. During the ensilage process, more lactic acid was produced in late-harvested giant reed than in early-harvested giant reed. Late-harvested giant reed had a higher lignin content and lower enzymatic digestibility than early-harvested giant reed. However, enzymatic digestibility of all the giant reed biomass was improved by the 90-day ensilage process, reaching levels of 43-46%. In summary, ensilage could be used for storing giant reed biomass harvested at different times and for improving its digestibility. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Jensen, Jesse T.; Cottingham, James P.

    2003-10-01

    Free reed instruments are characterized by high-volume airflow rates through the oscillating reeds. Measurements have been made of the average volume flow rate through a single American organ reed as a function of blowing pressure. In addition, measurements of average air velocity have been made at a grid of points close to the vibrating air-driven reed, mounted on the surface of a laboratory wind chest. These measurements supplement earlier investigations, which explored relations among the reed motion, airflow, and acoustic pressure associated with the vibration of free reeds. [M. Busha and J. P. Cottingham, J. Acoust. Soc. Am. 111, 2376 (2002)]. An attempt has been made to determine whether the left-right asymmetry due to the asymmetric shape (twist) of the reed is reflected in the airflow pattern. A graphing program has been developed so that the airflow pattern can be visualized in two or three dimensions.

    Full Text Available Spitz and Reed nevi, also called spindle and/or epithelioid cell nevi, are a special group of melanocytic lesions due to their peculiar clinical, dermoscopic and histopathological features. The study of these nevi is of great interest because both their nomenclature and classification are still a matter of discussion. Most importantly, the difficulty to differentiate them from melanoma can lead to inadequate therapies. In this context, dermoscopy, a link between clinical and anatomopathological examinations, appears as a helpful diagnostic tool whose accuracy can reach 93%. "Borderline" lesions are still a great challenge and object of research, including molecular studies. The present study explores the relevant characteristics of these nevi, with emphasis on dermoscopic findings, aiming at understanding their natural history, as well as discussing treatment and patient follow-up.Os nevos de Spitz e de Reed, ou também chamados nevos de células fusiformes e/ou epitelióides, formam um grupo especial de lesões melanocíticas, por suas características peculiares, tanto clínicas como dermatoscópicas e histopatológicas.

Neste contexto, surge a dermatoscopia, elo entre o exame clínico e o anatomopatológico, como método diagnóstico auxiliar importante cuja acurácia pode chegar a 93%. A grande dificuldade ainda são as lesões "borderline", motivo de pesquisas, incluindo estudos moleculares.

  12. Remapping the Constellation of Walter Benjamin’s Allegorical Method

    Directory of Open Access Journals (Sweden)

    Wong Jack

    2015-12-01

    Full Text Available The now-longstanding academic revival of allegory, as well as its import as a perennial buzzword of contemporary art criticism, owes much to a group of essays published in the journal October in the early 1980s. Authors Craig Owens and Benjamin Buchloh, in turn, drew a bloodline to the ideas of allegory that occupied Walter Benjamin throughout his literary career. However, whereas Benjamin saw allegory as the expression of a radical, indeed messianic, view of political possibility, the October writers found in allegory a counter-paradigm against Modernism that would resist the latter's totalizing tendencies by pursing its own deconstructive fate of “lack of transcendence.” In the following essay, I trace the source of this discrepancy to the crucial theological underpinnings of Benjamin's concept of allegory, without which the allegorical forms - appropriation and montage - produce not miraculous flashes of unmediated recognition but the permanent impossibility of communication.

  13. Shrubby Reed-Mustard Habitat: Parent Material, Soil, and Landscape Characteristics

    Kelly, L. S.; Boettinger, J. L.

    2012-12-01

    Shrubby reed-mustard (Glaucocarpum suffrutescens, a.k.a. Schoenocrambe suffrutescens, Glaucocarpum suffrutescens, or Hesperidanthus suffrutescens) is an endangered perennial shrub endemic to the southern Uinta Basin in northeast Utah. Only seven populations of shrubby reed-mustard have been identified. The arid area where the plant grows is rich in natural gas and oil deposits, as well as oil shale. Oil wells already dot the landscape, and there is significant concern that further development of these resources will threaten the continued existence of shrubby reed-mustard. Determination of the parent material, soil and landscape characteristics associated with shrubby reed-mustard habitat is imperative to facilitate conservation management. Shrubby reed-mustard grows where little else does and, based on field observations and remotely sensed spectral data, appears to occur in a particular type of strata. Our objective is to identify the physical and chemical characteristics of shrubby reed-mustard's environment. Site characteristics such as parent material and associated vegetation have been identified and documented. Soil properties such as water-soluble and total leachable elements, particle-size distribution, organic carbon, cation exchange capacity, total nitrogen, and available phosphorus and potassium are being determined. During the course of this investigation, soils within four shrubby reed-mustard habitat areas were sampled. Soils from non-shrubby reed-mustard areas adjacent to the four shrubby reed-mustard populations were also sampled. Soil samples were collected from a total of twenty-five shrubby reed-mustard soil pits and twenty-four non-shrubby reed-mustard soil pits. The soil horizons of each pedon were delineated, and samples were collected from each horizon. Field data indicate that shrubby reed-mustard occurs exclusively in shale-derived, shallow soils on bedrock-controlled uplands. Although there is some overlap of plant species on both types

RS encoding and RS decoding both with and without erasing code symbols are emphasized. There is no need to present rigorous proofs and extreme mathematical detail. Rather, the simple concepts of groups and fields, specifically Galois fields, are presented with a minimum of complexity. Before RS codes are presented, other block codes are presented as a technical introduction into coding. A primitive (15, 9) RS coding example is then completely developed from start to finish, demonstrating the encoding and decoding calculations and a derivation of the famous error-locator polynomial. The objective is to present practical information about Reed-Solomon coding in a manner such that it can be easily understood.

    A basic single-chip building block for a Reed-Solomon (RS) decoder system is partitioned into a plurality of sections, the first of which consists of a plurality of syndrome subcells each of which contains identical standard-basis finite-field multipliers that are programmable between 10 and 8 bit operation. A desired number of basic building blocks may be assembled to provide a RS decoder of any syndrome subcell size that is programmable between 10 and 8 bit operation.

    Logica has performed a study of Reed-Solomon coding in the context of protecting a mass memory in the harsh space environment, e.g., against galactic cosmic rays and heavy ion rich solar flares. The study examined the relation between the final bit error rate, the rate at which the code is used to scrub errors from the memory, and the rate at which errors occur. The RS(255,252) code was considered.

    Bladder function has interested man since prehistoric times. Evidence of health and well being was often measured from observation of urine. When urologic function was impaired, the extent of the ensuing pain often called for dramatic measures to obtain relief. The practice of urology has advanced substantially since the days when reeds were used to alleviate obstruction of the bladder. This article presents a brief historical overview of urology and the strides made in prostate surgery with modern technology.

    Calhoun, Mark T.

    On 12 Octther 1999, the U.S. Army began a journey down a new path to innovation, when General Eric Shinseki presented his vision of Army Transformation at the 45th annual meeting of the Association of the United States Army. In this speech, General Shinseki described the Army as an organization consisting of heavy forces with excellent staying power but poor strategic responsiveness, light forces with excellent responsiveness but poor staying power, and a logistics system with an excessively large footprint. His proposed solution, a comprehensive change of the Army resulting in full-spectrum dominance and strategic responsiveness, would occur so quickly as to "be unnerving to some." [Shinseki. 1999] While this prediction has turned out in some ways to be true, it is not necessarily the speed of change that is unnerving to many of the people studying Army Transformation.

  1. Custom CMOS Reed Solomon coder for the Hubble Space Telescope

    1990-01-01

    A VLSI coder is presented that can function either as an encoder or decoder for Reed-Solomon codes. VLSI is one approach to implementing high-performance Reed-Solomon decoders. There are three VLSI technologies that could be used: gate arrays, standard cells, and full custom. The first two approaches are relatively easy to implement, but are limited in both performance and density. Full-custom VLSI is used to achieve both circuit density and speed, and allows control of the amount of interconnect. Speed, which is a function of capacitance, which is a function of interconnect, is an important parameter in high-performance VLSI. A single 8.2 mm x 8.4 mm, 200,000 transistor CMOS chip implementation of the Reed-Solomon code required by the Hubble Space Telescope is reported. The chip features a 10-MHz sustained byte rate independent of error pattern. The 1.6-micron CMOS integrated circuit has complete decoder and encoder functions and uses a single data/system clock. Block lengths up to 255 bytes and shortened codes are supported with no external buffering. Erasure corrections and random error corrections are supported with programmable correction of up to 10 symbol errors. Correction time is independent of error pattern and the number of errors in the incoming message.

  2. Balanced Reed-Solomon codes for all parameters

    KAUST Repository

    Halbawi, Wael

    2016-10-27

    We construct balanced and sparsest generator matrices for cyclic Reed-Solomon codes with any length n and dimension k. By sparsest, we mean that each row has the least possible number of nonzeros, while balanced means that the number of nonzeros in any two columns differs by at most one. Codes allowing such encoding schemes are useful in distributed settings where computational load-balancing is critical. The problem was first studied by Dau et al. who showed, using probabilistic arguments, that there always exists an MDS code over a sufficiently large field such that its generator matrix is both sparsest and balanced. Motivated by the need for an explicit construction with efficient decoding, the authors of the current paper showed that the generator matrix of a cyclic Reed-Solomon code of length n and dimension k can always be transformed to one that is both sparsest and balanced, when n and k are such that k/n (n-k+1) is an integer. In this paper, we lift this condition and construct balanced and sparsest generator matrices for cyclic Reed-Solomon codes for any set of parameters.

  3. Decoding Generalized Concatenated Codes Using Interleaved Reed-Solomon Codes

    CERN Document Server

    Senger, Christian; Bossert, Martin; Zyablov, Victor

    2008-01-01

    Generalized Concatenated codes are a code construction consisting of a number of outer codes whose code symbols are protected by an inner code. As outer codes, we assume the most frequently used Reed-Solomon codes; as inner code, we assume some linear block code which can be decoded up to half its minimum distance. Decoding up to half the minimum distance of Generalized Concatenated codes is classically achieved by the Blokh-Zyablov-Dumer algorithm, which iteratively decodes by first using the inner decoder to get an estimate of the outer code words and then using an outer error/erasure decoder with a varying number of erasures determined by a set of pre-calculated thresholds. In this paper, a modified version of the Blokh-Zyablov-Dumer algorithm is proposed, which exploits the fact that a number of outer Reed-Solomon codes with average minimum distance d can be grouped into one single Interleaved Reed-Solomon code which can be decoded beyond d/2. This allows to skip a number of decoding iterations on the one...

  4. The utilisation of reed (Phragmites australis: a review

    Directory of Open Access Journals (Sweden)

    2013-10-01

    Full Text Available Reed (Phragmites is a wetland plant genus that has been utilised by man since ancient times. It is a tall, thin, highly productive grass (Poaceae with an above-ground biomass of up to 30 t ha-1 y-1. Due to its world-wide dominance, it is often cheap and readily available as a raw material. Reed has been used for centuries as a fodder plant in summer, and the stems have traditionally been harvested in winter as a raw material for crafts and for construction materials including roofing. It became popular for pulp and paper production in the middle of the twentieth century and, in recent years, has been used in sewage water treatment and as a source of renewable energy that is unlikely to compete with food production. This article explores the global extent of reedbeds and potential yields; and catalogues historical uses of reed, forgotten applications and new opportunities for its utilisation. Quality requirements, products and related stand management (such as harvesting time are also reviewed.

  5. Effect of urea addition on giant reed ensilage and subsequent methane production by anaerobic digestion.

    Liu, Shan; Ge, Xumeng; Liew, Lo Niee; Liu, Zhe; Li, Yebo

    2015-09-01

    The effect of urea addition on giant reed ensilage and sequential anaerobic digestion (AD) of the ensiled giant reed was evaluated. The dry matter loss during ensilage (up to 90 days) with or without urea addition was about 1%. Addition of 2% urea enhanced production of lactic acid by about 4 times, and reduced production of propionic acid by 2-8 times. Besides, urea addition reduced degradation of cellulose and hemicellulose, and increased degradation of lignin in giant reed during ensilage. Ensilage with or without urea addition had no significant effects on the enzymatic digestibility of giant reed, but ensilage with urea addition achieved a cumulative methane yield of 173 L/kg VS, which was 18% higher than that of fresh giant reed. The improved methane yield of giant reed could be attributed to the production of organic acids and ethanol during ensilage. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The giant reed (Arundo donax L.) is amongst the one hundred worst invasive alien species of the world, and it is responsible for biodiversity loss and failure of ecosystem functions in riparian habitats. In this work, field spectroradiometry was used to assess the spectral separability of the giant reed from the adjacent vegetation and from the common reed, a native similar species. The study was conducted at different phenological periods and also for the giant reed stands regenerated after mechanical cutting (giant reed_RAC). A hierarchical procedure using Kruskal-Wallis test followed by Classification and Regression Trees (CART) was used to select the minimum number of optimal bands that discriminate the giant reed from the adjacent vegetation. A new approach was used to identify sets of wavelengths - wavezones - that maximize the spectral separability beyond the minimum number of optimal bands. Jeffries Matusita and Bhattacharya distance were used to evaluate the spectral separability using the minimum optimal bands and in three simulated satellite images, namely Landsat, IKONOS and SPOT. Giant reed was spectrally separable from the adjacent vegetation, both at the vegetative and the senescent period, exception made to the common reed at the vegetative period. The red edge region was repeatedly selected, although the visible region was also important to separate the giant reed from the herbaceous vegetation and the mid infrared region to the discrimination from the woody vegetation. The highest separability was obtained for the giant reed_RAC stands, due to its highly homogeneous, dense and dark-green stands. Results are discussed by relating the phenological, morphological and structural features of the giant reed stands and the adjacent vegetation with their optical traits. Weaknesses and strengths of the giant reed spectral discrimination are highlighted and implications of imagery selection for mapping purposes are argued based on present results.

    2000-05-01

    Full Text Available Este artigo é uma leitura do texto de Walter Benjamin Paris capital do século XIX. A partir do conjunto de anotações que Benjamin faz de diversos livros consultados, principalmente durante sua pesquisa na Bibliothèque Nationale, o autor pretende trabalhar a noção de indivíduo vinculando-a a dois temas. Primeiro, a emergência do flâneur como tradução do espírito de mobilidade que se inaugura com a modernidade. Para isso a discussão sobre a noção de espaço, particularmente no que diz respeito a cidade de Paris, é importante. O flâneur surge assim como um indivíduo desenraizado que se locomove através do espaço urbano remodelado. Segundo, uma aproximação entre o ato da flânerie e o trabalho intelectual. Considerando a flânerie como uma atividade intelectual o autor mostra como os temas do distanciamento e da construção do objeto são relevantes tanto para o flâneur-detetive quanto para a reflexão nas ciências sociais.This paper is an interpretation of Walter Benjamins Paris, Capital of the 19th Century. Based on the notes Benjamin made on several books he read, mainly during his research at the Bibliotèque Nationale, the author discusses the notion of the individual linking it to two themes. First, to the emergence of the flâneur as a translation of the spirit of mobility which starts with modernity. The discussion on the notion of space, especially where it concerns Paris, is essential for this analysis. The flâneur is seen as an uprooted individual who moves around the remodelled urban space. Second, to the proximity between the act of flânerie and that of intellectual work. Taking flânerie to be intellectual activity, the author shows how the themes of the distancing and the construction of the object are relevant, both to the detective-flâneur and to the reflection in social sciences.

  19. Gerard Manley Hopkins and Walter Pater : the labyrinths of transience

    Directory of Open Access Journals (Sweden)

    Mirko Starčević

    2016-12-01

    Full Text Available Transience forming life's very essence left an indelible mark on the creative explorations of Gerard Manley Hopkins and Walter Pater. The permanently indeterminable presence of mutability made both of them face the umbrous and unknowable aspect of death, thus revealing unto them the task of determining the role of art in life ruled by ceaseless corrosion. Pater accepts the flux of mutability as the primary particle in the revelatory act of the authentic creative experience. The power of that which is frolicsome in art augments the constitution of life's essence submerged in the unsettled condition of fate. Hopkins the priest particularly in his theoretic excursions recognizes in art itself only an approximate value to the timeless grandeur of God's ubiquity. His poetry, however, presents a dissimilar narrative. The poetic image that Hopkins forges corresponds to the mode of exposed individuality of the Romantic spirit, which Pater perceives as the harmony of strangeness and beauty. During Hopkins' student days at Oxford, Pater's relationship to the young poet was not confined to coaching only. Much of their time they spent in conversation, meditating upon the essential principles of artistic expression. Pater influenced Hopkins greatly and contributed impressively to the discipline of his poetic heart. Traces of this companionship do not find the path to Hopkins' religious ruminations; they announce their own existence, although very subtly, upon the individual levels of Hopkins' poetic yearnings.

  20. Il desiderio Kitsch: i troppi paradisi di Walter Siti

    Directory of Open Access Journals (Sweden)

    Ornella Tajani

    2013-05-01

    Full Text Available Kitsch is the system where people live their lives as a commercial and their identity as an eternal performance. What happens there to desire? If in this utopia the man is supposed to live easily and pleasingly, how can he bear something out-of-hand such as desire? After a theoretical introduction on Kitsch, the paper will answer these questions basing on three Walter Siti’s works: the novels Troppi paradisi and Autopsia dell’ossessione and the narrative reportage Il canto del diavolo. Here the reader finds three paradigms of Kitsch experience: tourism, television, and a certain kind of prostitution. By investigating them, the paper will show how the desire changes its shape when it has to face the Kitschmensch’s tendency to disguise himself «dans le miroir du mensonge embellissant et de s’y reconnaître avec une satisfaction émue», as Kundera says. The marvellous and most sustainable lightness of being is then the Kitsch utopia cipher; it cannot consider the presence of desire but when it is feasible: the Kitsch desire, the ersatz of desire, is given for free with the product fulfilling it.

    This paper presents a new construction of Maximum-Distance Separable (MDS) Reed-Solomon erasure codes based on Fermat Number Transform (FNT). Thanks to FNT, these codes support practical coding and decoding algorithms with complexity O(n log n), where n is the number of symbols of a codeword. An open-source implementation shows that the encoding speed can reach 150Mbps for codes of length up to several 10,000s of symbols. These codes can be used as the basic component of the Information Dispersal Algorithm (IDA) system used in a several P2P systems.

    Hodgkin/Reed Stemberg (HRS) cells mediate the classical features of Hodgkin's disease. However, because of their rarity in tumor tissue, little is known about their origin and function. Recent advances in biotechnology, including the single cell manipulation, enabled the insight into the biology of HRS cell. It has been demonstrated that in the great majority of cases they are of germinal center B cell origin, with highly developed interactive network with adjacent cells via expression of cell adhesion molecules, tumor necrosis factor receptor superfamily, and elaboration of different cytokines.

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    The complexity of decoding the standard Reed-Solomon code is a well known open prob-lem in coding theory. The main problem is to compute the error distance of a received word. Using the Weil bound for character sum estimate, we show that the error distance can be determined precisely when the degree of the received word is small. As an application of our method, we give a significant improvement of the recent bound of Cheng-Murray on non-existence of deep holes (words with maximal error distance).

    Picart, P.; Leval, J.; Piquet, F.; Boileau, J.-P.; Dalmont, J.-P.

    2009-07-01

    This paper describes optical instrumentation devoted to vibration analysis. Two strategies based on digital Fresnel holography are presented. The first, called time-averaging consists in the numerical reconstruction of the hologram after recording with an exposure time much greater than the vibration period. Thus, the holograms are amplitude modulated by a Bessel function. The last strategy, using a pulsed regime, allows the reconstruction of the full movement of the vibration, even if it exhibits very high amplitude. Experimental results presented in this paper concern the study of the vibrations of a clarinet reed under free and forced oscillation regimes.

    2015-04-01

    Hichiriki is a traditional Japanese double-reed wind instrument used in Japanese ancient imperial court music, gagaku, which has been performed since the 7th century. The best reeds for hichiriki have been made of culms or stems of Phragmites australis (P. australis) that are harvested from only a limited reed bed at Udono near Kyoto. The aim of this study is to elucidate why the stems from Udono are the best materials for hichiriki reeds. Plant anatomy was examined for choice stems of P. australis grown in different reed beds in Japan as well as morphology, and the local indentation hardness and Young's modulus of tissues on the cross-sections of some representatives of hichiriki reeds were measured. It is concluded that the good stems for hichiriki reeds have an outer diameter of about 11 mm, a wall thickness of about 1 mm and comparatively homogeneous structure where harder materials, such as epidermis, hypodermis, sclerenchymatous cells, and vascular bundle sheaths with hard walls, are orderly deployed with softer materials such as parenchyma cells and vascular bundles. This structure has smaller differences of hardness and Young's modulus between the hard and soft materials in the reed, providing the best music performance.

    lignocelluloses usually do. In the present study, wet oxidation was investigated as the pretreatment method to enhance the enzymatic digestibility of reed cellulose to soluble sugars and thus improve the convertibility of reed to ethanol. The most effective treatment increased the digestibility of reed cellulose...... by cellulases more than three times compared to the untreated control. During this wet oxidation, 51.7% of the hemicellulose and 58.3% of the lignin were solubilized, whereas 87.1% of the cellulose remained in the solids. After enzymatic hydrolysis of pretreated fibers from the same treatment, the conversion......Common reed (Phragmites australis) is often recognized as a promising source of renewable energy. However, it is among the least characterized crops from the bioethanol perspective. Although one third of reed dry matter is cellulose, without pretreatment, it resists enzymatic hydrolysis like...

    2012-01-01

    A set of 55 clarinet reeds is observed by holography, collecting 2 series of measurements made under 2 different moisture contents, from which the resonance frequencies of the 15 first modes are deduced. A statistical analysis of the results reveals good correlations, but also significant differences between both series. Within a given series, flexural modes are not strongly correlated. A Principal Component Analysis (PCA) shows that the measurements of each series can be described with 3 factors capturing more than 90% of the variance: the first is linked with transverse modes, the second with flexural modes of high order and the third with the first flexural mode. A forth factor is necessary to take into account the individual sensitivity to moisture content. Numerical 3D simulations are conducted by Finite Element Method, based on a given reed shape and an orthotropic model. A sensitivity analysis revels that, besides the density, the theoretical frequencies depend mainly on 2 parameters: $E_L$ and $G_{LT}...

    Giant reed was used as precursor for making biochar in order for the adsorption of NH4 (+)-N from aqueous solution. And the adsorption of the product to NH4 (+)-N was examined. The surface features of biochar were investigated by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy/energy dispersive spectrometer (SEM-EDS), and X-ray diffraction (XRD). XRD patterns showed several peaks and correspond to the high amount of crystalline material. The crystals contain KCl, K2O, CaO, MgO, and SiO and possess high surface area which enhances adsorption. The influence of different parameters such as initial concentration, adsorption time, pH, and ionic strength has been carried out. The adsorption could reach equilibrium through 24 h reaction and had the best adsorption amount at the solution pH values from 7 to 9. The cation has great influence on the adsorption of NH4 (+)-N, whereas the anion exerted a weaker effect. The adsorption followed pseudo-first-order and pseudo-second-order models. And the intraparticle diffusion and desorption studies further elucidated that the mechanism of adsorption on the product was ion exchange. The product equilibrium data was well described by the Langmuir and Freundlich model. The maximum adsorption capacities were 1.490 mg/g. Biochar derived from giant reed at 500 °C was suggested as a promising adsorbent for the removal of NH4 (+)-N from slightly polluted wastewater.

    A radiative heat and mass transfer study of Walter's memory flow along a vertical cone with thermophoresis is completed in the presence of induced magnetic field. A mathematical model of Walter's memory flow is developed from the basis of studying Magnetohydrodynamics(MHD). Some dimensionless quantities have been used to transform the model to non-dimensional system of equations. The dimensionless unsteady, coupled and non-linear partial differential conservation equations for the boundary layer regime are solved by an efficient, accurate and unconditionally stable finite difference scheme of the Crank-Nicolson type. The features of the flow, heat and mass transfer characteristics within the boundary layer are analyzed by plotting graphs and the physical aspects are discussed in detail. The obtained results show that the impact of flow variables plays an important role in the Walter's memory flow. Last of all, some important findings of the present problem are concluded in this work.

    As contemporaries, Alvin C. Kraenzlein, and Walter B. Tewksbury had a great deal in common. They were both outstanding athletic performers and each became an intercollegiate record holder in track and field. In 1898, the New York Times reported that the University of Pennsylvania "at present has the best college athletes in the world, its two particular stars being Kraenzlein and Tewksbury." As close friends and college roommates during their student years at the University of Pennsylvania College of Dentistry, these two young men graduated in close succession (Walter, 1899; Alvin, 1900). Between them, Alvin and Walter won nine Olympic medals in Paris in 1900. Ultimately, as dentists and athletes, they individually and corporately left indelible imprints on track and field for all time.

    Full Text Available Common reed (Phragmites australis (Cav. Trin. ex Steud. is distributed widely throughout the world with various ecotypes. This research compares the functional traits and biomass allocation patterns of two contrasting reed ecotypes. Twelve pairs of aquatic and terrestrial reed samples were collected in northern China. Significant differences in functional traits between the two reed ecotypes were observed, while biomass allocation patterns of reed organs did not differ significantly except for at the root. The dry matter content (DMC in the whole of the reed plant, leaf, root, and rhizome was higher; while the specific leaf area (SLA and specific root length (SRL were lower in terrestrial versus aquatic reed. The biomass allocation in organs of the two forms of reed was isometric, only root in the terrestrial habitat increased faster with an increase in the whole plant biomass. It can be affirmed that aquatic and terrestrial reed that adapt to different environments generally has distinct leaf and root functional traits but isometric biomass allocation patterns. This suggests different resource acquisition strategies: (1 aquatic reed grows faster with high SLA and SRL and is more responsive to the environment, while (2 terrestrial reed with high DMC grows slower and is less responsive to the adverse environment (e.g. dry soil conditions.

  6. An exploration of common reed (Phragmites australis bioenergy potential in North America

    Directory of Open Access Journals (Sweden)

    R. Vaičekonytė

    2014-10-01

    Full Text Available In North America, reed (Phragmites australis is typically considered to be a weed although it provides important ecosystem services. Small, sparse, patchy or mixed reedbeds are more suitable as habitat for many species than extensive dense reedbeds, whose habitat functions can be enhanced by the selective removal of biomass. We propose that above-ground reed biomass could be harvested for bioenergy, at the same time improving habitat for biodiversity by thinning or fragmenting the more extensive reedbeds. Biofuel pellets manufactured from reeds harvested at Montréal (Canada had moisture content 6.4 %, energy content 16.9 kJ g-1 (dry mass, ash content 3.44 %, and chloride content 1962 ppm. Thus, reed as a material for fuel pellet manufacture is similar to switchgrass (Panicum virgatum, which is commonly cultivated for that purpose and requires higher inputs than harvested wild reed. We discuss these findings in the context of environmental considerations and conclude that the bioenergy potential of reed could most expediently be realised in North America by combining material harvested from the widespread spontaneously occurring reedbeds with organic waste from other sources to create mixed biofuels. However, reeds with high levels of chlorine, sulphur or metals should not be burned to avoid air pollution or equipment damage unless these problems are mitigated by means of appropriate season of harvest, equipment, combustion regime, or use of a mixed feedstock.

    Full Text Available Reed is a widespread-growing, inexpensive, and readily available lignocellulosic material source in northeast China. The objective of this study is to evaluate the liquid hot water (LHW pretreatment efficiency of reed based on the enzymatic digestibility and ethanol fermentability of water-insoluble solids (WISs from reed after the LHW pretreatment. Several variables in the LHW pretreatment and enzymatic hydrolysis process were optimized. The conversion of glucan to glucose and glucose concentrations are considered as response variables in different conditions. The optimum conditions for the LHW pretreatment of reed area temperature of 180°C for 20min and a solid-to-liquid ratio of 1 : 10. These optimum conditions for the LHW pretreatment of reed resulted in a cellulose conversion rate of 82.59% in the subsequent enzymatic hydrolysis at 50°C for 72 h with a cellulase loading of 30 filter paper unit per gram of oven-dried WIS. Increasing the pretreatment temperature resulted in a higher enzymatic digestibility of the WIS from reed. Separate hydrolysis and fermentation of WIS showed that the conversion of glucan to ethanol reached 99.5% of the theoretical yield. The LHW pretreatment of reed is a suitable method to acquire a high recovery of fermentable sugars and high ethanol conversion yield.

    The shorelines of lakes in northeastern Germany are often covered by reed. These reed belts fulfill an important function as erosion protection, biotope for animals, carbon storage, and as cleaning filter for lake water. However, despite their importance for the limnic ecosystem, reed vegetation in northeastern Germany is not regularly monitored. In this research study we investigate the potential of synthetic aperture radar polarimetry (PolSAR) for seasonal monitoring of reed vegetation. SAR imagery enables sunlight- and (almost) weather-independent monitoring. Polarimetric decomposition techniques allow the physical characterization of the scattering scenario and the involved scatterers. Our study is based on 19 dual-polarimetric (HH/VV) TerraSAR-X images acquired between August 2014 and May 2015. We calculated different polarimetric indices comprising the HH and VV intensities, the dual-polarimetric coherency matrix with dominant and mean alpha scattering angles, entropy and anisotropy (normalized eigen-value difference) as well as combinations of entropy and anisotropy for the analysis of the scattering scenarios. The reed areas in the TerraSAR-X images were classified using a random forest algorithm and validated with high-resolution digital orthophotos. The time series analysis of the reed belts revealed significant seasonal changes in the double bounce sensitive parameters (intensity ratio HH/VV and intensity difference HH-VV, the co-polarimetric coherence phase and the dominant and mean alpha scattering angles). Additionally, the dual-polarimetric coherence (amplitude), anisotropy, entropy, and anisotropy-entropy-combinations showed seasonal changes of reed. In summer, the reed areas are characterized within the X-band SAR data by volume scattering, whereas in winter double-bounce scattering dominates. The volume scattering in summer is caused predominantly by reed leaves. In autumn, the leaves start to wither and fall off, so that in winter predominately

    Reed Sternberg (RS) cells in the setting of small lymphocytic lymphoma (SLL) can complicate the histopathological diagnosis. We report a case of a man aged 54 years who presented with cervical lymphadenopathy. Resection of the lymph node was performed and sent for histopathological evaluation to a local laboratory. A diagnosis of SLL with Classic Hodgkin's lymphoma (CHL) was made. The medical oncologist who encountered this diagnosis for the first time sent the biopsy blocks to our laboratory for a second opinion. On review of the biopsy and immunohistochemical stains, it showed typical SLL morphology and immunophenotype. Focally, it showed large mononuclear RS type cells; however, no typical background of CHL was seen. The diagnosis was revised to 'SLL with RS like cells with no convincing evidence of CHL'. The patient was subsequently treated as a case of SLL and no progression was observed on a follow-up of 5 years. 2017 BMJ Publishing Group Ltd.

  13. Gravity Drainage of Activated Sludge on Reed Beds

    Christensen, Morten Lykkegaard; Dominiak, Dominik Marek; Keiding, Kristian;

    Activated sludge is a by-product from waste water treatment plants, and the water content in the sludge is high (> 90%). Among several methods to remove the water, sludge drying reed beds are often used to dewater the sludge by drainage. There is, however, no well-defined criterion for design...... has therefore been developed to measure relevant quality parameters: specific cake resistance, settling velocity and cake compressibility. It has been found that activated sludge form highly compressible cake even at the low compressive pressures obtained during drainage. Numerical simulation shows...... that the compressibility has a high influence on the drainage process especially during the start-up phases where the volumetric load on the sludge bed is critical. The load has to be low in order to ensure that the drainage properties of the bed are not destroyed. The data also shows that transport of activated sludge...

    Ensilage and fungal pretreatment of giant reed harvested from August through December were compared based on their effects on feedstock preservation, glucose yield, and subsequent methane production via anaerobic digestion (AD). Compared to fungal pretreatment, ensilage obtained lower total solids (Ensilage increased glucose and methane yields by 7-15% and 4-14%, respectively, for giant reed harvested from August through December. Fungal pretreatment failed for giant reed harvested in August and October with reduced glucose yields, and was effective for that harvested in November and December, with about 20% increases in glucose yield. However, hydrocarbon losses during fungal pretreatment offset the increased glucose yield, resulting in decreased methane yields by AD. In summary, ensilage was found to be more suitable than fungal pretreatment for giant reed storage and its methane production via AD. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Zeh, Alexander; Augot, Daniel

    2011-01-01

    The key step of syndrome-based decoding of Reed-Solomon codes up to half the minimum distance is to solve the so-called Key Equation. List decoding algorithms, capable of decoding beyond half the minimum distance, are based on interpolation and factorization of multivariate polynomials. This article provides a link between syndrome-based decoding approaches based on Key Equations and the interpolation-based list decoding algorithms of Guruswami and Sudan for Reed-Solomon codes. The original interpolation conditions of Guruswami and Sudan for Reed-Solomon codes are reformulated in terms of a set of Key Equations. These equations provide a structured homogeneous linear system of equations of Block-Hankel form, that can be solved by an adaption of the Fundamental Iterative Algorithm. For an $(n,k)$ Reed-Solomon code, a multiplicity $s$ and a list size $\\listl$, our algorithm has time complexity \\ON{\\listl s^4n^2}.

    Nitrate leaching contaminates groundwater. The objective of this study was to determine if reed and rice stalks could enhance denitrification and reduce nitrate leaching into groundwater. Artificial groundwater spiked with nitrate and field groundwater samples were tested in the columns in sand reactors packed with either reed or rice stalks. The maximum nitrate removal rates were determined to be 1.93 and 1.97 mg nitrate-N l(-1) h(-1), respectively, in the reed and rice stalk-packed columns. The maximum nitrate-nitrogen removal rate in reactors packed with reed stalk was 1.33 mg nitrate-N l(-1) h(-1) when experimented with natural groundwater. Chemical oxygen demand consumption was higher when rice stalk (176.1 mg l(-1)) was used as the substrate, compared to reed stalk (35.2 mg l(-1)) at the same substrate dosage. No nitrite accumulation was detected during the test. The results demonstrate that agricultural byproducts, such as reed and rice stalks, may be used as substrate amendments for enhanced denitrification in natural settings, such as lakeside lagoons, ditches or wetlands.

    Full Text Available This article is an initiative of presenting some elements of Walter Benjamin’s reflections about cinema, and, according to the author, it is an art that give the answers for the modern man perceptive longings, to whom any experience was denied. The cinema, “the work of art in the era of its technical reproduction”, is ultimately for the author the mark of a new perception, of a new relationship between public and the work of art: the collective perception. What the crowd searches is not the contemplation or the withdrawal in front of a work of art, but entertainment. The cinema insists on this characteristic of entertaining when it reproduces the benjaminian concept of “shock experience”, through successive exhibitions of its fragments and constantly interrupting the association of the spectators ideas, (reaffirming the character of amusement of the modern art. However, for the author, the cinema dialectically responds to the amusement as an appropriate instrument for a pedagogy of the crowds – through an emancipated art, the masses would also become emancipated.

  12. On Multiple Decoding Attempts for Reed-Solomon Codes

    CERN Document Server

    Nguyen, Phong S; Narayanan, Krishna R

    2010-01-01

    One popular approach to soft-decision decoding of Reed-Solomon (RS) codes is based on the idea of using multiple trials of a simple RS decoding algorithm in combination with successively erasing or flipping a set of symbols or bits in each trial. In this paper, we present an framework based on rate-distortion (RD) theory to analyze such multiple-decoding algorithms for RS codes. By defining an appropriate distortion measure between an error pattern and an erasure pattern, it is shown that, for a single errors-and-erasures decoding trial, the condition for successful decoding is equivalent to the condition that the distortion is smaller than a fixed threshold. Finding the best set of erasure patterns for multiple decoding trials then turns out to be a covering problem which can be solved asymptotically by rate-distortion theory. Thus, the proposed approach can be used to understand the asymptotic performance-versus-complexity trade-off of multiple errors-and-erasures decoding of RS codes. We also consider an a...

  13. Mycobacterial Arthritis and Synovitis in Painted Reed Frogs (Hyperolius marmoratus).

    Several species of atypical mycobacteria have been isolated from wild and captive amphibians. In captive anurans, cutaneous and visceral mycobacteriosis are common and can result in significant mortality, particularly when animals are immunocompromised. Mycobacterial arthritis and synovitis are reported rarely in amphibians. We describe 20 cases in painted reed frogs (Hyperolius marmoratus), which presented with cachexia, limb paresis or paralysis or 'spindly leg syndrome'. Histopathology revealed multifocal histiocytic to granulomatous synovitis affecting appendicular, rib or spinal intervertebral joints. Periarticular granulomata, granulomatous cellulitis and skeletal muscle atrophy, necrosis and degeneration were also present. In one case, granulomatous spinal osteomyelitis was recorded. Ziehl-Neelsen stains showed large numbers of acid-fast bacteria in macrophages and histiocytes. The mycobacterial isolates obtained from culture were identified as members of the Mycobacterium chelonae complex (either M. chelonae or Mycobacteriumabscessus). This was confirmed by 5'-16S ribosomal ribonucleic acid (rRNA) sequencing. In 17 cases mycobacterial lesions were present only in the joints and skeleton, highlighting the importance of not ruling out mycobacterial infection on the basis of absence of cutaneous or visceral lesions.

    2014-11-01

    As a fast growing plant, giant reed has good potential to be used as a feedstock for methane production via anaerobic digestion (AD). The effect of total solids (TS) content, an AD operating parameter, was studied. Results showed that increasing TS from 8% to 38% decreased methane yield, due to the inhibition of volatile fatty acids (VFAs) and total ammonia nitrogen (TAN); while the maximum volumetric methane production was obtained at 20-23% TS. Comparison of solid-state AD (SS-AD) at 20% TS and liquid AD (L-AD) at 8% TS was conducted at feedstock to effluent (F/E) ratios of 2.0, 3.5, and 5.0. The best performance was achieved at an F/E of 2.0, with methane yields of 129.7 and 150.8L-CH4/kg-VS for SS-AD and L-AD, respectively. Overall organic components were degraded by 17.7-28.5% and 24.0-26.6% in SS-AD and L-AD, respectively; among which cellulose showed the highest degradation rate and the highest contribution to methane production.

    DC magnetization, AC magnetic susceptibility, vibrating reed (VR) and magnetoresistance measurements were performed on CeRux (x 2.0) samples. CeRu2 has been proposed as an unconventional superconductor based on heat capacity data (Sereni et al., 1989). A small interval of reversible, positive DC magnetization just below the upper critical field H_c2 followed by a region of giant magnetic hysteresis (GMH) at lower temperature (Roy, 1992; Yagasaki et al., 1993) suggest the existence of a "Fulde-Farrell" state (Huxley et al., 1993). We find a dip in the VR dissipation 1/Q that implies a peak effect in the critical current density exists at the lower boundary of the GMH region. VR hysteresis extends from this boundary to well below the GMH region, within which a large 1/Q peak is found to exhibit no hysteresis. We infer the magnetic response is drive and frequency dependent nearly everywhere below H_c2. The field dependence of 1/Q implies that a plastically deformed vortex lattice or glass phase exists well below the GMH region. * Funded by NSF Grant #EHR-9108764

    The effect of dilute sodium hydroxide (NaOH) on reed straw structural change at 105 degreeC temperature was evaluated in this study. Various concentrations of NaOH (1% to 2.5%) were used for pretreatment of reed straw at 105 degreeC for 10min. Scanning electron microscopy, atomic force microscopy and Fourier transform infrared spectroscopy studies showed that 2% and 2.5% NaOH pretreated sample exposed more cellulose fibers compared with other treatments. The cellulose crystalline index was increased by the 1% to 2.0% NaOH treatments and slightly lowered by the 2.5% NaOH treatment due to destructing cellulose fibres. Two per cent NaOH pretreatment caused 69.9% lignin removal, whereas 2.5% NaOH pretreatment removed 72.4% lignin. Besides, reed straw, when pretreated at 2% and 2.5% NaOH, resulted 56.4% and 60.5% hemicellulose removal, respectively. However, the difference in removal of lignin and hemicellulose between 2% and 2.5% NaOH treated reed straw was very marginal. In addition, very negligible increase of cellulose level was estimated, amounting 78.8% and 76.6% in 2.5% and 2% NaOH-treated sample, respectively. Moreover, after 72 h, reducing sugar yield was 81.2% and 83.3% using enzyme loading of 15 FPU (g dry biomass)-' and 30 IU (g dry biomass)- and xylanase 4 FXU (g dry biomass)-1 from 2% and 2.5% NaOH pretreated reed straw, respectively. Reducing sugar yield was increased very marginally when NaOH concentration increased from 2% to 2.5% for reed straw pretreatment. Therefore, 2% NaOH is supposed to be effective for reed straw pretreatment at this mentioned condition.

    Baseball maintains one of the highest impact injury rates in all athletics. A principal causative factor is the "beanball," referring to a pitch thrown directly at a batter's head. Frequent morbidities elicited demand for the development of protective gear development in the 20th century. In this setting, Dr. Walter Dandy was commissioned to design a "protective cap" in 1941. His invention became widely adopted by professional baseball and inspired subsequent generations of batting helmets. As a baseball aficionado since his youth, Walter Dandy identified a natural partnership between baseball and medical practice for the reduction of beaning-related brain injuries. This history further supports the unique position of neurosurgeons to leverage clinical insights, inform innovation, and expand service to society.

    Full Text Available Viscoelastic Walters' B fluid flows for three problems, stagnation-point flow, Blasius flow, and Sakiadis flow, have been investigated. In each problem, Cauchy equations are changed to a nondimensional differential equations using stream functions and with assumption of boundary layer flow. The fourth-order predictor-corrector finite-difference method for solving these nonlinear differential equations has been employed. The results that have been obtained using this method are compared with the results of the last studies, and it is clarified that this method is more accurate. It is also shown that the results of last study about Sakiadis flow of Walter's B fluid are not true. In addition, the effects of order of discretization in the boundaries are investigated. Moreover, it has been discussed about the valid region of Weissenberg numbers for the second-order approximation of viscoelastic fluids in each case of study.

  6. The tortoise and the love-machine: Grey Walter and the politics of electroencephalography.

    Science.gov (United States)

    Hayward, R

    2001-12-01

    The life of the pioneer electroencephalographer, William Grey Walter, initially appears to be a paradigmatic example of the process of network building and delegation identified by Michel Callon and Bruno Latour. In his professional career, Walter continually repositioned himself, moving from an unhappy beginning as an expert in the apparently unless and suspect technology of the EEG, to become a self-styled crucial mediator in subjects as diverse as medical diagnosis, forensic detection, marriage counseling, and international diplomacy. This position was achieved moreover through the construction and co-option of human and mechanical accomplices - laboratory assistants, electrical tortoises, and mechanical analyzers - which sustained his research and propagated his arguments. However in contrast to Callon and Latour's atomistic account of scientific power and agency, this paper will extend their analysis to explore the impact of network building and delegation on domestic life, human desire, and personal identity. Walter's engagement with the complexities of love and the human brain demonstrates how the transformative power of scientific rhetoric extends simultaneously into both the organization of the world and the subjectivity of the individual.

    Full Text Available In the following pages I would like to try the quite tight interpretation that carries out Theodor Wiesengrund Adorno of the overflowing and complex philosophical work of Walter Benjamin. In order to do it I shall use the text titled Sobre Walter Benjamin, published by Cátedra, Madrid, 1995. In this book they are compiled both: some texts around the philosophical work of Benjamin and some of the letters directed by Adorno to his friend. Be worth to denote that several of the works are later to the death of Benjamín.

    Full Text Available Synthetic aperture radar polarimetry (PolSAR and polarimetric decomposition techniques have proven to be useful tools for wetland mapping. In this study we classify reed belts and monitor their phenological changes at a natural lake in northeastern Germany using dual-co-polarized (HH, VV TerraSAR-X time series. The time series comprises 19 images, acquired between August 2014 and May 2015, in ascending and descending orbit. We calculated different polarimetric indices using the HH and VV intensities, the dual-polarimetric coherency matrix including dominant and mean alpha scattering angles, and entropy and anisotropy (normalized eigenvalue difference as well as combinations of entropy and anisotropy for the analysis of the scattering scenarios. The image classifications were performed with the random forest classifier and validated with high-resolution digital orthophotos. The time series analysis of the reed belts revealed significant seasonal changes for the double-bounce–sensitive parameters (intensity ratio HH/VV and intensity difference HH-VV, the co-polarimetric coherence phase and the dominant and mean alpha scattering angles and in the dual-polarimetric coherence (amplitude, anisotropy, entropy, and anisotropy-entropy combinations; whereas in summer dense leaves cause volume scattering, in winter, after leaves have fallen, the reed stems cause predominately double-bounce scattering. Our study showed that the five most important parameters for the classification of reed are the intensity difference HH-VV, the mean alpha scattering angle, intensity ratio HH/VV, and the coherence (phase. Due to the better separation of reed and other vegetation (deciduous forest, coniferous forest, meadow, winter acquisitions are preferred for the mapping of reed. Multi-temporal stacks of winter images performed better than summer ones. The combination of ascending and descending images also improved the result as it reduces the influence of the sensor

    2017-03-04

    Phragmites australis has been used to treat acid mine drainage (AMD)-contaminated soil. However, the mechanism about metal translocation in reeds was not widely reported. This study investigated metal (Fe, Al, and Mn) storage location in reeds grown in five different sampling sites of an AMD field. As expected, the more metals in soil, the more metals entered the belowground organs of plants. Reeds grown in soils with the highest levels of metals accumulated 0.16 ± 0.04 mg/g Mn, 16.29 ± 4.15 mg/g Fe, and 1.31 ± 0.22 mg/g Al in roots. Most of the iron was sequestered in the roots, while Al was transferred to the shoots. Histological staining found that most of the iron was sequestered in the exodermis, while Al extended the endodermis of roots. Al even entered the stele of roots grown in soil with higher Al levels. The epidermis, cortex, and central cylinder of rhizomes were the main tissues for Fe and Al storage. The more metals in rhizomes, the stronger intensity of the staining was observed around the vascular systems of rhizomes. No structural difference was observed among reeds collected from different sites. Further studies may be needed to enhance the transfer of metals in reeds and increase the phytoremediation efficiency.

  17. Thermal transmittance of reed-insulated walls in a purpose-built test house

    2014-03-01

    Full Text Available We studied the construction and thermal properties of walls insulated with reed, to enable comparisons with other wall structures that are widely used in building. In 2010 we built a test house insulated with reed adjacent to the Estonian University of Life Sciences in Tartu. The load-bearing structure of the house was a timber frame, and four different technologies were used to place reed insulation in its external walls. The thickness of the reed layer was 450 mm in all cases, and both sides (inside and outside of the walls were rendered with clay plaster. Records were kept of time spent and materials used in construction of the different types of walls, and these data were used to calculate unit (m-2 requirements of time and materials for each wall type to enable direct comparisons. From October 2010 to March 2012, heat flow plates were used to measure the thermal transmittance of the walls of the completed house and the results were compared with the thermal transmittance requirements set by Estonian legislation. Only one of the test walls met the Estonian standard. This was insulated with compressed loose reed, placed horizontally in the wall.

    The obligate avian brood parasitic common cuckoo Cuculus canorus comprises different strains of females that specialize on particular host species by laying eggs of a constant type that often mimics those of the host. Whether cuckoos are locally adapted for mimicking populations of the hosts on which they are specialized has never been investigated. In this study, we first explored the possibility of local adaptation in cuckoo egg mimicry over a geographical mosaic of selection exerted by one of its main European hosts, the reed warbler Acrocephalus scirpaceus. Secondly, we investigated whether cuckoos inhabiting reed warbler populations with a broad number of alternative suitable hosts at hand were less locally adapted. Cuckoo eggs showed different degrees of mimicry to different reed warbler populations. However, cuckoo eggs did not match the egg phenotypes of their local host population better than eggs of other host populations, indicating that cuckoos were not locally adapted for mimicry on reed warblers. Interestingly, cuckoos exploiting reed warblers in populations with a relatively larger number of co-occurring cuckoo gentes showed lower than average levels of local adaptation in egg volume. Our results suggest that cuckoo local adaptation might be prevented when different cuckoo populations exploit more or fewer different host species, with gene flow or frequent host switches breaking down local adaptation where many host races co-occur.

  19. Numerical and experimental modal analysis of the reed and pipe of a clarinet

    Science.gov (United States)

    Facchinetti, Matteo L.; Boutillon, Xavier; Constantinescu, Andrei

    2003-05-01

    A modal computation of a complete clarinet is presented by the association of finite-element models of the reed and of part of the pipe with a lumped-element model of the rest of the pipe. In the first part, we compare modal computations of the reed and the air inside the mouthpiece and barrel with measurements performed by holographic interferometry. In the second part, the complete clarinet is modeled by adjoining a series of lumped elements for the remaining part of the pipe. The parameters of the lumped-resonator model are determined from acoustic impedance measurements. Computed eigenmodes of the whole system show that modal patterns of the reed differ significantly whether it is alone or coupled to air. Some modes exhibit mostly reed motion and a small contribution of the acoustic pressure inside the pipe. Resonance frequencies measured on a clarinet with the mouthpiece replaced by the cylinder of equal volume differ significantly from the computed eigenfrequencies of the clarinet taking the actual shape of the mouthpiece into account and from those including the (linear) dynamics of the reed. This suggests revisiting the customary quality index based on the alignment of the peaks of the input acoustical impedance curve.

  20. A new upper bound on the query complexity for testing generalized Reed-Muller codes

    CERN Document Server

    Ron-Zewi, Noga

    2012-01-01

    Over a finite field $\\F_q$ the $(n,d,q)$-Reed-Muller code is the code given by evaluations of $n$-variate polynomials of total degree at most $d$ on all points (of $\\F_q^n$). The task of testing if a function $f:\\F_q^n \\to \\F_q$ is close to a codeword of an $(n,d,q)$-Reed-Muller code has been of central interest in complexity theory and property testing. The query complexity of this task is the minimal number of queries that a tester can make (minimum over all testers of the maximum number of queries over all random choices) while accepting all Reed-Muller codewords and rejecting words that are $\\delta$-far from the code with probability $\\Omega(\\delta)$. (In this work we allow the constant in the $\\Omega$ to depend on $d$.) In this work we give a new upper bound of $(c q)^{(d+1)/q}$ on the query complexity, where $c$ is a universal constant. In the process we also give new upper bounds on the "spanning weight" of the dual of the Reed-Muller code (which is also a Reed-Muller code). The spanning weight of a co...

    Full Text Available The anatomical structure and chemical composition of the stem-wall material of giant reed is considered from the viewpoint of raw material characterization for industrial fiber production. The effect of stem morphology (nodes and internodes on pulping results and general pulp properties is discussed. The advantages of application of modern organic solvent based (organosolv pulping technologies to giant reed are shown in comparison with the conventional (kraft method. The conditions optimization for Ethanol-Alkali pulping (a selected organosolv pulping process is given, and the chemical kinetics of the principal macromolecular components during ethanol-alkali pulping is described. The bleachability of organosolv pulps by short totally chlorine free (TCF bleaching sequences using hydrogen peroxide and ozone as the active bleaching chemicals without pulp pre-delignification is examined and compared with kraft pulps. The enzymatic pre-treatment of reed organosolv pulps by commercial xylanase preparation is considered as a possibility toward the improvement of pulp bleachability.

    2016-05-15

    Many studies have been conducted recently on an integrated hybrid actuator due to the increasing need for unmanned aircraft and guided weapons. In this study, flow distribution was analyzed for a reed valve which was used for flow regulation to improve the performance of the actuator. By using a Fluid structural interaction (FSI) technique with Computational fluid dynamics (CFD) having a moving mesh, numerical analysis was performed according to the thickness, shape and driving frequency of the reed valve. From the calculated results, the maximum performance of the reed valve was found at the valve thickness of 0.15 mm and the driving frequency of 250 Hz for a no-load state. The optimum thickness and shape for the valve for each driving frequency were also realized.

  5. Measurements on microscopic barium ferrite single crystals using a vibrating reed magnetometer

    Schippan, R.; Hempel, K. A.

    1982-11-01

    The magnetization processes occuring in a small individual particle (dimensions about 4 μm) of a barium ferrite single crystal are investigated using a high sensitivity vibrating reed magnetometer.1,2 With this apparatus magnetic moments smaller than 10-9 A cm2 may be detected if the particle is fixed to a hollow quartz reed which is kept under vacuum. The operating frequency is tuned to the resonance frequency of the reed. The examination exhibits a perfect rectangular primary hysteresis loop which indicates that the magnetic moment of the sample is completely reversed by a single Barkhausen jump. By repeating the reversal, a wide range of jump field strengths is revealed. Two types of minor loops are demonstrated depending on the magnitude of the jump field strength.

  6. Effect of Ripeness and Drying Process on Sugar and Ethanol Production from Giant Reed (Arundo donax L.

    Directory of Open Access Journals (Sweden)

    Egidio Viola

    2015-04-01

    Full Text Available The work highlighted the influence of the water content within the starting biomass, drying procedure and ripeness on the enzymatic digestibility of the giant reed, one of the most suitable nonfood crops for bioenergy and bio-compound production. Fresh green reed was treated as received, while oven-dried green and ripe reed were humidified before the steam explosion pretreatment that was carried out at 210 ℃ for 10 minutes. The exploded biomasses were extracted with water to remove the soluble hemicellulose and potential inhibitors; the insoluble residue was submitted to enzymatic hydrolysis and alcoholic fermentation. The process was evaluated in terms of sugars recovery and ethanol yield. After the sequence of pretreatment, enzymatic hydrolysis and fermentation by Saccharomyces cerevisiae 132 g; 103 g; 162 g of ethanol; and 77 g; 63 g; 92 g of pentosanes were respectively obtained from 1 kgDM of fresh green reed; dried green reed or ripe reed. The ripe reed contains more carbohydrates than the green reed and the resulting sugar and ethanol production was higher, in spite of lower saccharification yield. While drying the fresh biomass is good practice for biomass preservation, it negatively affects the recovery of free sugars and the ethanol production, because of fiber hornification which hinders enzyme access in the hydrolysis step.

  13. Differences in breeding bird assemblages related to reed canary grass cover cover and forest structure on the Upper Mississippi River

    Science.gov (United States)

    Kirsch, Eileen M.; Gray, Brian R.

    2017-01-01

    Floodplain forest of the Upper Mississippi River provides habitat for an abundant and diverse breeding bird community. However, reed canary grass Phalaris arundinacea invasion is a serious threat to the future condition of this forest. Reed canary grass is a well-known aggressive invader of wetland systems in the northern tier states of the conterminous United States. Aided by altered flow regimes and nutrient inputs from agriculture, reed canary grass has formed dense stands in canopy gaps and forest edges, retarding tree regeneration. We sampled vegetation and breeding birds in Upper Mississippi River floodplain forest edge and interior areas to 1) measure reed canary grass cover and 2) evaluate whether the breeding bird assemblage responded to differences in reed canary grass cover. Reed canary grass was found far into forest interiors, and its cover was similar between interior and edge sites. Bird assemblages differed between areas with more or less reed canary grass cover (.53% cover breakpoint). Common yellowthroat Geothlypis trichas, black-capped chickadee Parus atricapillus, and rose-breasted grosbeak Pheucticus ludovicianus were more common and American redstart Setophaga ruticilla, great crested flycatcher Myiarchus crinitus, and Baltimore oriole Icterus galbula were less common in sites with more reed canary grass cover. Bird diversity and abundance were similar between sites with different reed canary grass cover. A stronger divergence in bird assemblages was associated with ground cover ,15%, resulting from prolonged spring flooding. These sites hosted more prothonotary warbler Protonotaria citrea, but they had reduced bird abundance and diversity compared to other sites. Our results indicate that frequently flooded sites may be important for prothonotary warblers and that bird assemblages shift in response to reed canary grass invasion.

  16. The French Army and British Army Crimean War Reforms

    Directory of Open Access Journals (Sweden)

    Anthony Dawson

    2015-05-01

    Full Text Available French army logistics of the Crimean War are generally considered to have been better organized than their British counterpart. This sometimes erroneous belief was fuelled by letters home (from officers and men as well as by the reporting of various ‘special correspondents’ in the Crimea, and created an emotional response favourable to the ordinary soldier and, in particular, towards the French. This then became the basis for arguments for reform of the British army in the military and domestic press and in Parliament. Clamour for reform on French lines led to official studies being made of the French army, especially of logistics, officer education, and even uniforms. The French army, however, was little understood and the resulting ephemeral corps-style units (such as Land Transport Corps, Army Work Corps, and Mounted Staff Corps were quickly found faulty. In fact, official study of the French army often had little or no effect on the major reforms of the war. Emulation of the French was ultimately short-lived and of little effect; the favourable perception of the French was based on short-term emotional response and, indeed, the desire for army reform had its sting drawn with the establishment of the Roebuck Committee. Post-war retrenchment and success in the Indian Mutiny would stifle what was left of the reform debate.

    Quispe, Walter Álvarez; Loza, Carmen Beatriz

    2014-01-01

    Walter Álvarez Quispe, a Kallawaya healer and biomedical practitioner specializing in general surgery and gynecology, presents the struggle of traditional and alternative healers to get their Andean medical systems depenalized between 1960 and 1990. Bolivia was the first country in Latin America and the Caribbean to decriminalize traditional medicine before the proposals of the International Conference on Primary Health Care (Alma-Ata, 1978). The data provided by the interviewee show that the successes achieved, mainly by the Kallawayas, stem from their own independent initiative. These victories are not the result of official policies of interculturality in healthcare, although the successes achieved tend to be ascribed to them.

    In 1926-1927, a graduate student, B. C. Graves, working with Stanford University psychologist Walter Miles and legendary football coach Pop Warner, conducted an investigation of variations in signal calling as they affected the charging times of football players. The study was one of two that involved Miles and the ingenious multiple chronograph that he had invented to time the reactions of seven players simultaneously. These studies represented a brief digression in the career of Miles, who certainly was no sport psychologist. They tell of an interesting collaboration between scientist and coaches that produced one of the richest studies in sport psychology in the first half of the twentieth century.

    Full Text Available Although Sir Walter Scott is a well-known writer most of his readers know that he became an advocate in 1792, when he was admitted to the bar. Since then Scott and other advocates walked the floor at Parliament House (home of the Faculty of Advocates and the Court of Session waiting to be hired. Scott’s own experiences as a fledgling advocate are echoed in those of Alain Fairford in his novel Redgauntlet (Scott 1824, which provides a vivid picture of Parliament House in the eighteenth century. During his life, Scott combined extensive writing and editing issues with his daily work as Clerk of Session and Sheriff-Depute of Selkirkshire. Walter Scott was not unaware of Justice and Law and The Heart of Mid-Lothian is the novel in which he introduces to the reader the Scottish Legal System during the eighteenth century. However, there are few more examples that I will explain. Aunque Sir Walter Scott es un conocido escritor, la mayoría de sus lectores saben que en 1792 se hizo abogado, cuando fue admitido en el colegio de abogados. Desde entonces Scott y otros abogados rondaron el Parlamento con la esperanza de ser contratados. Las propias experiencias de Scott como un abogado novel se reflejan en las de Alain Fairford en su novela Redgauntlet (Scott 1824, lo que ofrece una vívida imagen del Parlamento (sede de la facultad de Derecho y Tribunal Supremo en el siglo XVIII. Durante su vida, Scott compaginó una profusa actividad como escritor y editor con su trabajo diario como juez en Selkirk. Walter Scott conocía la justicia y el derecho y El corazón de Mid-Lothian es la novela en la presenta al lector el régimen jurídico de Escocia durante el siglo XVIII.

  9. Geographic intersections of regional science: Reflections on Walter Isard's contributions to geography

    Science.gov (United States)

    Glasmeier, Amy

    . In his writing, analyses, and commentaries, Walter Isard contributed significantly to economic geography, inspiring a generation of economic geographers with seminal texts on industrial location and spatial economics and methods of regional analysis - a line of argumentation that explicitly incorporated economic reasoning into an otherwise largely descriptive and inventory-based subdiscipline of geography. His circumscribed view of regional development and industrial location helped precipitate the emergence of the critical turn in economic geography in the late 1970s. He was the one early modern 20th century economics author to successfully wed economics and a certain perspective on space.

    2009-09-01

    Lake Baiyangdian, a largest wetland ecosystem in North China Plain, has dried up on seven occasions since the 1960s. In recent years, more than one billion of cubic meters of water from upstream reservoirs and Yellow river have been transported to the lake to rescue the shrinking wetlands. Since the Lake Baiyangdian was actually composed of 143 small lakes and more than 70 villages with large or small area of cropland, dynamic distribution of aquatic plants in wetland such as reed and associated growth condition of these allowed to monitor the changes of wetland landscape and water quality to support the policy applications of water conveyance and wetland environmental treatment and control. Assisted with ground survey analyses and Landsat TM image, the MODIS 250 m time series Normalized Difference Vegetation Index (NDVI), given its combination of medium spatial and high temporal resolution, were applied to detect the unique rapid growth stage of reed in the spring from adjacent crops such as winter wheat, cotton, and spring maize, of which has a similar phenology in development of leaf area index, and dynamic reed areas were mapped in recent decade. Landscape changes of the wetland were analyzed using maps of reed area and hydrological data.

  14. ADVANCES IN CLOG STATE MONITORING FOR USE IN AUTOMATED REED BED INSTALLATIONS

    Directory of Open Access Journals (Sweden)

    Theodore HUGHES-RILEY

    2014-06-01

    Full Text Available Constructed wetlands are a popular form of waste-water treatment that have proliferated across Europe and the rest of the world in recent years as an environmentally conscious form of waste water treatment. The ability to monitor the conditions in the bed and control input factors such as heating and aeration may extend the lifetime of the reed bed substantially beyond the ten year lifetime normally reached. The Autonomous Reed Bed Installation (ARBI project is an EU FP7 initiative to develop a reed bed with automated control over input parameters based on readings taken from embedded sensors. Automated remedial action may improve bed treatment efficiency, and prolong the life of the bed and avoiding the need to refurbish the bed, which is both time consuming and costly. One critical parameter to observe is the clog state of the reed bed, as this can severely impact on the efficiency of water treatment to the point of the bed becoming non-operable. Magnetic resonance (MR sensors can be a powerful tool in determining clogging levels, and has previously been explored in the literature. This work is based on a conference paper (2nd International Conference "Water resources and wetlands", 2014 and details magnetic sensors suitable for long-term embedding into a constructed wetland. Unlike previous studies this work examines a probe embedded into a wetland.

  15. Monocotyledons in Particleboard Production: Adhesives, Additives, and Surface Modification of Reed Canary Grass

    Directory of Open Access Journals (Sweden)

    Johann Trischler

    2014-05-01

    Full Text Available As a supplier to the furniture industry, the particleboard industry is searching for opportunities to reduce costs, weight, and formaldehyde emissions. One such opportunity is to use monocotyledons such as straw and hemp, as well as grasses like reed canary grass. A major problem when using reed canary grass or other monocotyledons in combination with wood is the difference in their surface properties, leading to poor reactivity and wettability with adhesives such as melamine urea formaldehyde. To this end, either the surface of the particles must be modified in some way, or different adhesives must be used. The purpose of this paper is to present adhesives, surfactants, coupling agents, and pre-treatment methods that can be used in combination with monocotyledons to improve compatibility with wood. Some of the methods have been tested on reed canary grass. The results show a wide range of strength values for the joint between wood and untreated or pre-treated reed canary grass glued with different adhesives, with and without a surfactant and a coupling agent. Isocyanate-based adhesives provided relatively strong bonds, and polyvinyl acetate, acryl, and epoxy adhesives were also effective. The most effective method was pre-treatment followed by adhesives in combination with a coupling agent.

  18. Reed warbler hosts fine-tune their defenses to track three decades of cuckoo decline.

    Thorogood, Rose; Davies, Nicholas B

    2013-12-01

    Interactions between avian hosts and brood parasites can provide a model for how animals adapt to a changing world. Reed warbler (Acrocephalus scirpaceus) hosts employ costly defenses to combat parasitism by common cuckoos (Cuculus canorus). During the past three decades cuckoos have declined markedly across England, reducing parasitism at our study site (Wicken Fen) from 24% of reed warbler nests in 1985 to 1% in 2012. Here we show with experiments that host mobbing and egg rejection defenses have tracked this decline in local parasitism risk: the proportion of reed warbler pairs mobbing adult cuckoos (assessed by responses to cuckoo mounts and models) has declined from 90% to 38%, and the proportion rejecting nonmimetic cuckoo eggs (assessed by responses to model eggs) has declined from 61% to 11%. This is despite no change in response to other nest enemies or mimetic model eggs. Individual variation in both defenses is predicted by parasitism risk during the host's egg-laying period. Furthermore, the response of our study population to temporal variation in parasitism risk can also explain spatial variation in egg rejection behavior in other populations across Europe. We suggest that spatial and temporal variation in parasitism risk has led to the evolution of plasticity in reed warbler defenses.

  20. Development of the reed bed in Matsalu wetland, Estonia: responses to neotectonic land uplift, sea level changes and human influences

    Full Text Available We studied reed bed development in Matsalu wetland and the Kasari River delta, Estonia, since the late 18th century using historical schemes, topographical maps and aerial photographs. Our aim was to understand the mechanisms controlling reed distribution in Matsalu wetland, the largest coastal wetland of the eastern Baltic Sea occupying an area of about 25 km2. Natural development of the reed bed in Matsalu Bay and the Kasari delta is mainly controlled by shoreline displacement due to post-glacial neotectonic land uplift. The dredging of the Kasari delta in the 1920s–1930s caused a rapid seaward migration of reed bed communities due to the dispersal of fragmented rhizomes on the shallow sea bottom and along the canal banks reaching Matsalu Bay, while the landward parts of the former wetland were occupied by meadow communities. The expansion of the reed bed started in between the 1951s and 1970s and a maximum extent of 27 km2 was gained by the late 1970s at the peak of eutrophication. In the last decades the reed bed development has been influenced by sea level rise and increased intensity of cyclonic activity in the Baltic Sea, which has caused the deterioration of the reed bed that was weakened by eutrophication due to nutrient inflow from agricultural landscapes mainly in the 1960s–1980s.

    The aim of this study was to test fuel blends of briquettes and chopped reed canary grass in three existing heating plants (50 kW - 500 kW) and elucidate the requirements for good performance and low emissions. In addition, the study investigated production of reed canary grass briquettes using a Polish screw press developed for straw. Some tests with a bale shredder were also undertaken. The screw press technique is of interest for reed canary grass because it is a simple technique, easy to handle, developed for small scale production, and for straw. The test with reed canary grass in this study showed that the technique worked well but that further adjustments and a longer test period are needed in order to achieve higher bulk density and mechanical strength. The test with chopped reed canary grass shows that a system with a forage harvester is slightly more effective than baling and cutting in a bale shredder. The study concluded that few existing heating plants of size 50 kW-1 MW that currently use wood fuels will be able to use reed canary grass without adjustment, conversion or replacement of the combustion equipment. Reed canary grass has 15-20 times higher ash content than wood briquettes and 2-3 times higher ash content than forest residue; the combustion equipment must be able to handle these properties. The boiler must be equipped with a continuously operating ashing system and it must be possible to move the ash bed mechanically. There is a risk of high content of unburned matter if the residence time in the boiler is too short, due to the structure and low bulk density of the reed canary grass ash. Using a blend of wood briquettes and reed canary briquettes results in lower ash content, but also affects the ash chemistry and tends to lower the initial ash fusion temperature compared to using 100 % reed canary grass. Blending chopped reed canary grass and wood chips in an existing small scale heating plant also requires measures to achieve an even fuel

  2. Glycoproteomic characterization of carriers of the CD15/Lewisx epitope on Hodgkin's Reed-Sternberg cells

    Full Text Available Abstract Background The Lewisx trisaccharide, also referred to as the CD15 antigen, is a diagnostic marker used to distinguish Hodgkin's lymphoma from other lymphocytic cancers. However, the role of such fucosylated structures remains poorly understood, in part because carriers of Lewisx structures on Hodgkin's Reed-Sternberg cells have not been identified. Methods GalMBP, an engineered carbohydrate-recognition protein that binds selectively to oligosaccharides with paired terminal galactose and fucose residues, has been used in conjunction with proteomic and glycomic analysis to identify glycoprotein carriers of Lewisx and related glycan structures in multiple Hodgkin's Reed-Sternberg cell lines. Results Multiple glycoproteins that bind to GalMBP and carry CD15/Lewisx have been identified in a panel of six Reed-Sternberg cell lines. The most commonly identified Lewisx-bearing glycoproteins are CD98hc, which was found in all six cell lines tested, and intercellular adhesion molecule-1 and DEC-205, which were detected in five and four of the lines, respectively. Thus, several of the most prominent cell adhesion molecules on the lymphomas carry this characteristic glycan epitope. In addition, the Hodgkin's Reed-Sternberg cell lines can be grouped into subsets based on the presence or absence of less common Lewisx-bearing glycoproteins. Conclusions CD98 and intercellular adhesion molecule-1 are major carriers of CD15/Lewisx on Reed-Sternberg cells. Binding of DC-SIGN and other glycan-specific receptors to the Lewisx epitopes on CD98 and intercellular adhesion molecule-1 may facilitate interaction of the lymphoma cells with lymphocytes and myeloid cells in lymph nodes.

    2013-03-01

    The difference in the removal efficiencies of polycyclic aromatic hydrocarbons (PAHs) in planted and unplanted sludge drying bed was investigated. Pilot-scale sludge drying bed and reed bed had the same size of 3.0 m x 1.0 m x 1.3 m (L x W x H), and the bed height consisted of a 65 cm media layer and a 65 cm super height. Both beds had a ventilation pipe which was mounted on the drainage pipes. The experiment lasted for three years, and the first two years was the sludge loading period, and the third year was the natural stabilization period. In the first two years, a total thickness of 8.4 m of sludge was loaded and the average sludge loading rate was 41.3 kg x (m2 x a)(-1). After the three-year stabilization, the contents of the sixteen PAHs decreased with time in both the sludge drying bed and the reed bed. The total PAHs contents in the surface, middle and bottom sludge layers in the sludge drying bed were 4.161, 3.543 and 3.118 mg x kg(-1) (DW), corresponding to 26.91%, 37.77% and 45.23% of removal; and the values in the reed bed were 2.722, 1.648 and 1.218 mg x kg(-1) (DW), corresponding to 52.18%, 71.05% and 78.60% of removal. The average PAHs removal in the reed bed was 29.86% higher than that in the sludge drying bed. In the stabilized sludge, the removal of low-molecular-weight PAHs predominated. The results suggested that reed played a positive role in the removal of PAHs.

  5. A Theoretical Method for Estimating Performance of Reed-Solomon Codes Concatenated with Orthogonal Space-Time Block Codes

    Based on the studies of Reed-Solomon codes and orthogonal space-time block codes over Rayleigh fading channel, a theoretical method for estimating performance of Reed-Solomon codes concatenated with orthogonal space-time block codes is presented in this paper. And an upper bound of the bit error rate is also obtained. It is shown through computer simulations that the signal-to-noise ratio reduces about 15 dB or more after orthogonal space-time block codes are concatenate with Reed-Solomon (15,6) codes over Rayleigh fading channel, when the bit error rate is 10-4.

    2013-09-01

    Over many decades Walter Creutz, medical officer in the provincial administration of Rhine Province from 1935 to 1945, was held to be one of the few psychiatrists who had actively opposed the Nazi "Euthanasia" program. In the famous "Euthanasia trial" in Düsseldorf from 1948 to 1950, Creutz was acquitted of complicity in murder; the court attested that he had done his best to sabotage the "Euthanasia" program and in so doing had saved up to 3,000 patients in the Rhineland. This rendering was circulated further in the history of science literature, so that the Rhine Province was considered to be a center of resistance to the "Euthanasia" program. Doubts about this portrayal have arisen since the 1980s. Various authors attempted to prove that Walter Creutz collaborated with the "Euthanasia" apparatus claiming there was no evidence of opposition or resistance or only to a very limited degree. However, this new perspective is based on an equally one-sided, at times grossly distorted analysis of the sources. The article provides building blocks for a more differentiated interpretation.

    2017-09-01

    At the peak of his career, Walter J. Freeman II was a celebrated physician and scientist. He served as the first chairman of the Department of Neurology at George Washington University and was a tireless advocate of surgical treatment for mental illness. His eccentric appearance, engaging personality during interviews, and theatrical demonstrations of his surgical techniques gained him substantial popularity with local and national media, and he performed more than 3000 prefrontal and transorbital lobotomies between 1930 and 1960. However, poor patient outcomes, unfavorable portrayals of the lobotomy in literature and film, and increased regulatory scrutiny contributed to the lobotomy's decline in popularity. The development of antipsychotic medications eventually relegated the lobotomy to rare circumstances, and Freeman's reputation deteriorated. Today, despite significant advancements in technique, oversight, and ethical scrutiny, neurosurgical treatment of mental illness still carries a degree of social stigma. This review presents a historical account of Walter Freeman's life and career, and the popularization of the lobotomy in the US. Additionally, the authors pay special attention to the influence of popular literature and film on the public's perception of psychosurgery. Aided by an understanding of this pivotal period in medical history, neurosurgeons are poised to confront the ethical and sociological questions facing psychosurgery as it continues to evolve.

Hice algunos ajustes en nuestra traducción inicial. También seleccioné términos que actúan como reveladores de la trama conceptual que atraviesa en filigrana este ensayo. Por ejemplo, el uso del adverbiointensiv o la noción de ingenium. Por último, he dedicado un amplio desarrollo a la importancia que comporta, -para entender bien la estrategia narrativa puesta en funcionamiento en el prólogo de Benjamín-, el uso de metáforas de origen cabalístico que inscriben claramente el texto en la tradición mística judía. No estoy de acuerdo en este punto con el tratamiento bastante laxo que Antoine Berman ha dado a este aspecto, que

  14. Response of reed community to the environment gradient water depth in the Yellow River Delta, China

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    We investigated and monitored a reed community in the fields.Data on the bio-ecologieal characteristics and β-diversity of reed communities in different environmental gradients (mainly based on water depth) of the Yellow River Delta were collected through multianalysis,extremum analysis and β-diversity index analysis.In accordance with the square sum of deviations (Ward)cluster analysis,10 sampling plots were divided into six types with the dominant plants in different plots varying according to the change in environmental gradients.The dominant plants in these plots varied from aquatic plants to xerophytes and salt tolerant plants as water depth decreased.The average height and diameter of the reeds at breast level were significantly correlated with the average water depth.The fitness curves of average density and coverage with average water depth were nonlinear.When the average water depth was 0.3 m,the average density and coverage of reeds reached the apex value,while the height and diameter of the reeds at breast level increased with the water depth.There were obvious changes to the environmental gradient in the Yellow River Delta.The transitional communities were also found to exist in the Yellow River Delta by β-diversity analysis.Vicarious species appeared with the change in water depth.The occurrence of substitute species is determined by the function of common species between adjacent belts.The different functions of common species led to differences in community structure and function and differences in dominant plants.The result reflects the variations of species present in different habitats and directly reflects environmental heterogeneity.The values of//-diversity indices of adjacent plots were higher than those of nonadjacent plots.There are transition zones between the xerophytes and aquatic plants in the Yellow River Delta.In an aquatic environment,the similarity of reed community is higher than that of xeromorphic plants.The β-diversity index

    The temperature/pH dual sensitivity reed hemicellulose-based hydrogels have been prepared through glow discharge electrolysis plasma (GDEP). The effect of different discharge voltages on the temperature and pH response performance of reed hemicellulose-based hydrogels was inspected, and the formation mechanism, deswelling behaviors of reed hemicellulose-based hydrogels were also discussed. At the same time, infrared spectroscopy (FT-IR), scanning differential thermal analysis (DSC) and scanning electron microscope (SEM) were adopted to characterize the structure, phase transformation behaviors and microstructure of hydrogels. It turned out to be that all reed hemicellulose-based hydrogels had a double sensitivity to temperature and pH, and their phase transition temperatures were all approximately 33 °C, as well as the deswelling dynamics met the first model. In addition, the hydrogel (TPRH-3), under discharge voltage 600 V, was more sensitive to temperature and pH and had higher deswelling ratio.

    Garí Calzada, Mayra A; Iputo, Jehu E

    2015-07-01

    INTRODUCTION Problem-based learning harmonized with education in and for the community is the cornerstone of the curriculum for the undergraduate medical degree at Walter Sisulu University, Mthatha, South Africa. In tutorials, students construct knowledge and learn to work collaboratively while interacting with one another in their search for solutions to a pedagogically modeled health issue based on a patient. Problems cover students' needs defined by the learning cycle of the second year medical curriculum, organized into four learning blocks. OBJECTIVES Determine student perspectives on which factors affect tutorial group functioning and detect the reported presence of these factors in the four learning blocks comprising the second year of medical studies at Walter Sisulu University. METHODS Twenty second-year medical students were chosen by stratified random sampling and assigned to two focus groups. One group discussed factors that foster smooth functioning of the tutorial group; the other focused on factors hindering effective group work. Later, in a joint session, 17 items previously identified by both groups were selected and included in a survey given to all 97 students at the end of second year. The survey assessed presence of each item in 0, 1, 2, 3 or 4 of the learning blocks. RESULTS Survey response was 93.8%. Mean reported presence of factors that influenced tutorials in the four learning blocks was 2.71 (SD 0.31) for the social dimension, 3.02 for motivational (SD 0.02), 3.00 for cognitive (SD 0.42), and 2.22 for self-directed learning (SD 0.79). CONCLUSIONS Tutorial group performance at Walter Sisulu University is positively influenced more by motivational and cognitive factors than by social and self-directed learning factors. Social dimensions should be prioritized when training tutors and self-directed learning stressed for students. The poor productivity of extra-tutorial group discussions suggests the need for a critical evaluation of this

    Chronic lymphocytic leukemia (CLL) is known to undergo Richter transformation in a proportion of cases. Transformation into Hodgkin lymphoma has been described in a minority of the cases. However, CLL rarely also shows Hodgkin and Reed-Sternberg cells with a classic morphology and the immunophenotype of Hodgkin lymphoma, even when not in transformation. The presence of these Hodgkin and Reed-Sternberg cells in CLL can cause a diagnostic dilemma.

    2003-01-01

    The efficacy of plants as means of decontaminating hydrocarbon-polluted soil has been studied. Ditch reed (Phragmites australis) and alfalfa (Medicago sativa) markedly intensified processes of pollutant destruction, the effect being particularly pronounced in the case of polycyclic aromatic hydrocarbons (PAHs). Comparative analysis of microflora in soils (including those devoid of plants and rhizosphere) demonstrated that, in addition to preventing the pollutant-induced decrease in the amount of heterotrophic microorganisms, the plants stimulated their development, significantly increasing the population of destructors. Effects of plants on major physiological groups of soil microorganisms under conditions of pollution were ambiguous. The rhizosphere consortium of alfalfa was less susceptible to effects of pollutants than that of reed.

    2015-02-01

    As the volume of data acquired by space-based sensors increases, mission data compression/decompression and forward error correction code processing performance must likewise scale. This competency development effort was explored using the General Purpose Graphics Processing Unit (GPGPU) to accomplish high-rate Rice Decompression and high-rate Reed-Solomon (RS) decoding at the satellite mission ground station. Each algorithm was implemented and benchmarked on a single GPGPU. Distributed processing across one to four GPGPUs was also investigated. The results show that the GPGPU has considerable potential for performing satellite communication Data Signal Processing, with three times or better performance improvements and up to ten times reduction in cost over custom hardware, at least in the case of Rice Decompression and Reed-Solomon Decoding.

    2010-01-01

    A Reed-Solomon code of length n can be list decoded using the well-known Guruswami-Sudan algorithm. By a result of Alekhnovich (2005) the interpolation part in this algorithm can be done in complexity O(s^4l^4nlog^2nloglogn), where l denotes the designed list size and s the multiplicity parameter....... The parameters l and s are sometimes considered to be constants in the complexity analysis, but for high rate Reed-Solomon codes, their values can be very large. In this paper we will combine ideas from Alekhnovich (2005) and the concept of key equations to get an algorithm that has complexity O(sl^4nlog^2...

  11. Discrete logarithm computations over finite fields using Reed-Solomon codes

    CERN Document Server

    Augot, Daniel

    2012-01-01

    Cheng and Wan have related the decoding of Reed-Solomon codes to the computation of discrete logarithms over finite fields, with the aim of proving the hardness of their decoding. In this work, we experiment with solving the discrete logarithm over GF(q^h) using Reed-Solomon decoding. For fixed h and q going to infinity, we introduce an algorithm (RSDL) needing O (h! q^2) operations over GF(q), operating on a q x q matrix with (h+2) q non-zero coefficients. We give faster variants including an incremental version and another one that uses auxiliary finite fields that need not be subfields of GF(q^h); this variant is very practical for moderate values of q and h. We include some numerical results of our first implementations.

    Full Text Available Reed's syndrome is an autosomal dominant genetic disorder. Affected individuals are at increased risk of developing benign smooth muscle tumors in the skin and uterus. In this article, we report a case of a 52-year-old female who presented to our dermatology clinic complaining of painful skin lesions on her right arm, left forearm and trunk. The patient had a past medical history of uterine leiomyomatosis for which she underwent hysterectomy 17 years ago. The patient's family history revealed that her mother, 2 sisters and 2 maternal aunts also had uterine leiomyomas. The diagnosis of Reed's syndrome was confirmed by histopathologic examination of the patient's dermal lesion in conjunction with her surgical and family histories. Five years after the initial presentation, the patient underwent treatment with liquid nitrogen cryotherapy for the dermal leiomyomas. After the treatment, marked improvement was noticed with regard to the pain and size of the skin lesions.

  13. Evaluating the Value of High Spatial Resolution in National Capacity Expansion Models using ReEDS

    Krishnan, Venkat; Cole, Wesley

    2016-11-14

    Power sector capacity expansion models (CEMs) have a broad range of spatial resolutions. This paper uses the Regional Energy Deployment System (ReEDS) model, a long-term national scale electric sector CEM, to evaluate the value of high spatial resolution for CEMs. ReEDS models the United States with 134 load balancing areas (BAs) and captures the variability in existing generation parameters, future technology costs, performance, and resource availability using very high spatial resolution data, especially for wind and solar modeled at 356 resource regions. In this paper we perform planning studies at three different spatial resolutions--native resolution (134 BAs), state-level, and NERC region level--and evaluate how results change under different levels of spatial aggregation in terms of renewable capacity deployment and location, associated transmission builds, and system costs. The results are used to ascertain the value of high geographically resolved models in terms of their impact on relative competitiveness among renewable energy resources.

  14. On locality of Generalized Reed-Muller codes over the broadcast erasure channel

    2016-07-28

    One to Many communications are expected to be among the killer applications for the currently discussed 5G standard. The usage of coding mechanisms is impacting broadcasting standard quality, as coding is involved at several levels of the stack, and more specifically at the application layer where Rateless, LDPC, Reed Slomon codes and network coding schemes have been extensively studied, optimized and standardized in the past. Beyond reusing, extending or adapting existing application layer packet coding mechanisms based on previous schemes and designed for the foregoing LTE or other broadcasting standards; our purpose is to investigate the use of Generalized Reed Muller codes and the value of their locality property in their progressive decoding for Broadcast/Multicast communication schemes with real time video delivery. Our results are meant to bring insight into the use of locally decodable codes in Broadcasting. © 2016 IEEE.

    2006-02-01

    With the announcement by William Lennox at the 1935 London International Neurology Congress of the use of electroencephalography in the study of epilepsy, it became evident that a new and powerful technique for the investigation of seizures had been discovered. William Grey Walter, a young researcher finishing his post-graduate studies at Cambridge, was selected to construct and study the EEG in clinical neurology at the Maudsley Hospital, London. His hugely productive pioneering career in the use of EEG would eventually lead to groundbreaking work in other fields --the emerging sciences of robotics, cybernetics, and early work in artificial intelligence. In this historical note his pioneering work in the fields of clinical neurophysiology is documented, both in the areas of epileptology and tumour detection. His landmark contributions to clinical neurophysiology are worthy of documentation.

    Aruncus dioicus (Walter) Fernald is an herbaceous plant belonging to the Rosaceae family. In the northern regions of Italy young shoots of A. dioicus are collected and used as vegetable. No studies on the chemical composition of young shoots of A. dioicus have been reported so far. Thus, the aim of the present paper was to develop and validate a comprehensive chromatographic method allowing the identification and quantification of chemical compounds occurring in A. dioicus shoots harvested at different developmental stages. The results showed that shoots contain mainly polyphenols. Twenty-four compounds were detected. Caffeoylglucose derivatives were recognized as major compounds. It was also confirmed that shoots contain the cyanogenic compound prunasin at all investigated vegetation stages. It was shown that the prunasin content significantly increases during plant development, thus justifying the belief that after the development of the first green leaves, shoots should not be used for culinary purposes any longer.

This anthropology of childhood is deeply rooted in his memories of child “around 1900” and is patiently reconstructed from the picture books, from the games and the vintage toys, from the images and the characters that fill fantastic stories and fairy tales, from domestic and family rituals, from the world of objects and atmospheres of the bourgeois intérieur, Above all, this anthropology brings to light images. These images have a peculiar feature, a distinctive sign: they seem brought together by the idea and the experience of the threshold, a crucial figure in the epistemology of Benjamin.

    Prof. Walter Kohn presents "Electronic structure of matter : wave functions and density functionals".Since the 1920's Schroedinger wave functions have been the principal theoretical concept for understanding and computing the electronic structure of matter. More recently, Density Functional Theory (DFT), couched in terms of the electronic density distribution, n(r), has provided a new perspective and new computational possibilities, especially for systems consisting of very many (up to ~1000) atoms. In this talk some fundamental limitations of wave function methods for very-many-atom-systems will be discussed. The DFT approach will be explained together with some physical/chemical applications and a discussion of its strenghts and weaknesses.

    Full Text Available The linear stability of viscoelastic nanofluid layer is investigated. The rheological behavior of the viscoelastic fluid is described through the Walter's model. The normal modes analysis is utilized to treat the equations of motion for stationary and oscillatory convection. The stability analysis resulted in a third-degree dispersion equation with complex coefficients. The Routh–Hurwitz theory is employed to investigate the dispersion relation. The stability criteria divide the plane into several parts of stable/unstable regions. This shows some analogy with the nonlinear stability theory. The relation between the elasticity and the longitudinal wave number is graphically analyzed. The numerical calculations show that viscoelastic flows are more stable than those of the Newtonian ones.

  6. Blood and the Revenant in Walter Scott's The Fair Maid of Perth.

    2014-01-01

    In Sir Walter Scott's The Fair Maid of Perth; or St Valentine's Day (1828), the resuscitated subject is referred to as a revenant, a term that Scott borrowed from Henry Thomson's Blackwoodian tale 'Le Revenant' (1827), meaning 'dead-alive'. Taking its cue from the sanguinary subtext of The Fair Maid of Perth, which is fascinated with the shedding of blood and transfusion of fluids, this chapter reads the Scottish revenant as a literary reflection on the extraordinary promise of blood transfusion in the 1820s: that death could be understood as a process, rather than an absolute state, and that medical intervention could restore life to those on the brink of death and even to the recently deceased.

    2012-01-01

    Inequalities arise as an essential component in various mathematical areas. Besides forming a highly important collection of tools, e.g. for proving analytic or stochastic theorems or for deriving error estimates in numerical mathematics, they constitute a challenging research field of their own. Inequalities also appear directly in mathematical models for applications in science, engineering, and economics. This edited volume covers divers aspects of this fascinating field. It addresses classical inequalities related to means or to convexity as well as inequalities arising in the field of ordinary and partial differential equations, like Sobolev or Hardy-type inequalities, and inequalities occurring in geometrical contexts. Within the last five decades, the late Wolfgang Walter has made great contributions to the field of inequalities. His book on differential and integral inequalities was a real breakthrough in the 1970’s and has generated a vast variety of further research in this field. He also organize...

  12. The vibrating reed frequency meter: digital investigation of an early cochlear model

    Directory of Open Access Journals (Sweden)

    Andrew Bell

    2015-10-01

    Full Text Available The vibrating reed frequency meter, originally employed by Békésy and later by Wilson as a cochlear model, uses a set of tuned reeds to represent the cochlea’s graded bank of resonant elements and an elastic band threaded between them to provide nearest-neighbour coupling. Here the system, constructed of 21 reeds progressively tuned from 45 to 55 Hz, is simulated numerically as an elastically coupled bank of passive harmonic oscillators driven simultaneously by an external sinusoidal force. To uncover more detail, simulations were extended to 201 oscillators covering the range 1–2 kHz. Calculations mirror the results reported by Wilson and show expected characteristics such as traveling waves, phase plateaus, and a response with a broad peak at a forcing frequency just above the natural frequency. The system also displays additional fine-grain features that resemble those which have only recently been recognised in the cochlea. Thus, detailed analysis brings to light a secondary peak beyond the main peak, a set of closely spaced low-amplitude ripples, rapid rotation of phase as the driving frequency is swept, frequency plateaus, clustering, and waxing and waning of impulse responses. Further investigation shows that each reed’s vibrations are strongly localised, with small energy flow along the chain. The distinctive set of equally spaced ripples is an inherent feature which is found to be largely independent of boundary conditions. Although the vibrating reed model is functionally different to the standard transmission line, its cochlea-like properties make it an intriguing local oscillator model whose relevance to cochlear mechanics needs further investigation.

    Research was conducted at Middle East Technical University (METU), Ankara, Turkey in 2000 to determine whether a reed bed filled with an economical Turkish fill media that has high phosphorus (P) sorption capacity, could be implemented and operated successfully under field conditions. In batch-scale P-sorption experiments, the P-sorption capacity of the blast furnace granulated slag (BFGS) of KARDEMIR Iron and Steel Ltd., Co., Turkey, was found to be higher compared to other candidate filter materials due to its higher Ca content and porous structure. In this regard, a vertical subsurface flow constructed wetland (CW) (30 m(2)), planted with Phragmites australis was implemented at METU to treat primarily treated domestic wastewater, at a hydraulic rate of 100 mm d(-1), intermittently. The layers of the filtration media constituted of sand, BFGS, and gravel. According to the first year monitoring study, average influent and effluent total phosphorus (TP) concentrations were 6.61+/-1.78 mg L(-1) and 3.18+/-1.82 mg L(-1); respectively. After 12 months, slag samples were taken from the reed bed and P-extraction experiments were performed to elucidate the dominant P-retention mechanisms. Main pools for P-retention were the loosely-bounded and Ca-bounded P due to the material's basic conditions (average pH>7.7) and higher Ca content. This study indicated the potential use of the slag reed bed with higher P-removal capacity for secondary and tertiary treatment under the field conditions. However, the P-sorption isotherms obtained under the laboratory conditions could not be used favorably to determine the longevity of the reed bed in terms of P-retention.

    2014-12-01

    Full Text Available The abrasion processing of shores is a pressing problem of large water basins of the Lower Volga region and other Russian regions. About 3 km2 of shoreland is annually lost in the zone of the Volgograd water basin as a result of this process. The existing methods of shores protection are connected with the creation of concrete structures having a high level of erosion resistance. They are extremely expensive and in most cases they are not affordable for rural municipalities suffering from abrasion. The authors offer cheap and environmentally friendly way of protecting the shores of large water basins from abrasion. The method is based on the plantation of a common reed strip on a water basin’s shallow. The biological characteristics of common reed as the main component of shore protection structures are described. The terms and milestones of the work in the conditions of the Volgograd water basin are developed. The main result of applying our methodology is the complete cessation of abrasion processing of the shore at the corresponding piece of land. The authors overview the positive qualities of reed plantations, their biocenotic, barrier and waterproof role in on-shore ecosystems. The application of the described method will allow saving for the national economy dozens of hectares of valuable shore lands annually, in particular, irrigated cropland, settlement lands, infrastructure. In addition to the direct benefits associated with the conservation of land resources, the intensity of adverse processes associated with erosion of shores (water basin muddying, deterioration of sanitary qualities of water will decrease. Due to the wide geographic spread of common reed described in the present work, the technology of shores stabilization can be applied at almost all lowland water basins of Russia.

    This report presents results from cultivation trials all over Sweden with reed canary grass (Phalaris arundinacea) performed during 1990-1999. The work has focused on long-term use in the spring harvest system to show the sustainability in production. The trials, started 1990, clearly show that the spring harvest system is sustainable and gives high yields with good quality. Still after 8 years there is continuously high yield in the spring harvest system on soils suitable for reed canary grass, which are humus-rich sandy soils with good water supply. Chemical analyses of many years harvested crop have now verified that concentrations of undesired elements are low and have low variation between years. The important ash content differs considerably between different soil conditions. Sandy and humus-rich soils have a favourable low ash content, but clayey soils with low humus content give high ash content in the crop. Results from this project will now make it possible to do more accurate calculations of the production economy of reed canary grass.

  1. Reduction of the suction losses through reed valves in hermetic reciprocating compressors using a magnet coil

    Reed valves are widely used in hermetic reciprocating compressors and are responsible for a large part of the thermodynamic losses. Especially, the suction valve, which is opened nearly during the whole suction stroke, has a big potential for improvement. Usually, suction valves are opened only by vacuum created by the moving piston and should be closed before the compression stroke starts to avoid a reversed mass-flow through the valve. Therefore, the valves are prestressed, which results on the other hand in a higher flow resistance. In this work, a suction valve is investigated, which is not closed by the preload of the valve but by an electromagnetic coil located in the suction muffler neck. Shortly before the piston reaches its bottom dead centre, voltage is applied to the coil and a magnetic force is generated which pulls the valve shut. Thereby, the flow resistance through the valve can be reduced by changing the preload on the reed valve because it is no longer needed to close the valve. The investigation of this adapted valve and the electromagnetic coil is firstly done by numerical simulations including fluid structure interactions of the reed valves of a reciprocating compressor and secondly by experiments made on a calorimeter test bench.

    The richness, phylogeny and composition of archaeal community associated with the roots of common reed (Phragmites australis) growing in the Beijing Cuihu Wetland, China was investigated using a 16S rDNA library. In total, 235 individual sequences were collected, and a phylogenetic analysis revealed that 69.4 and 11.5 % of clones were affiliated with the Euryarchaeota and the Crenarchaeota, respectively. In Euryarchaeota, the archaeal community was dominated by species in following genera: Methanobacterium in the order Methanobacteriales (60.7 %); Methanoregula and Methanospirillum in the order Methanomicrobiales (20.2 %), and Methanomethylovorans, Methanosarcina and Methanosaeta in the order Methanosarcinales (17.2 %). Of 27 sequences assigned to uncultured Crenarchaeota, 22 were grouped into Group 1.3, and five grouped into Group 1.1b. Hence, the archaeal communities associated with reed roots are largely involved in methane production, and, to a lesser extent, in ammonia oxidization. Quantification of the archaeal amoA gene indicated that ammonia oxidizing archaea were more numerous in the rhizosphere soil than in the root tissue or surrounding water. A total of 19.1 % of the sequences were unclassified, suggesting that many unidentified archaea are probably involved in the reed wetland ecosystem.

    Reed canary grass (RCG) is a bio-energy crop with large potential. It is a 1.5 . 2.5 m tall grass that is harvested in spring when it is grown as a fuel. At spring harvest it yields 3 . 10 ton field dried material per ha and year. One disadvantage when reed canary grass is used as a fuel is the high ash content, 5-10 %. This means that large quantities of ash have to be deposited which is expensive, about 1000 SEK/ton. However, since reed canary grass ash contains reasonable amounts of plant nutrients like phosphorous (P), potassium (K) and magnesium (Mg) it could be recycled as fertilizer in agriculture. The ash can be used without any pretreatment since, in agriculture, plant availability is desirable. The aim of this project, was to evaluate a field experiment, where ash was used as a fertilizer in reed canary grass. The experiment was established at the SLU research station in Umea, Sweden in the spring 2002. Three different fertilizer treatments were applied: Treatment A was fertilized with an ash produced by combustion of RCG together with municipal wastes (paper, plastic, leather), treatment B, an ash from combustion of RCG, and for treatment C commercial fertilizers were used. In total, 100 kg ha-1 of nitrogen (N), 15 kg ha-1 of phosphorous (P) and 80 kg ha-1 of potassium (K), were applied each year in all treatments. The amount of ash in treatment A and B was calculated from the chemical analysis of the ashes to be equal to the required amount of P, while K and N were supplied also by commercial fertilizers. [Table 1. Composition of the ashes] Literature study: There is a lack of knowledge about fertilization with reed canary grass ash, since few experiments have been conducted. The composition of reed canary grass is dependent of harvest date and the soil substrate. The amount of ash and the amount of harmful substances such as potassium and chloride generally decreases over winter, giving an increased fuel quality from spring harvest compared to autumn

    Recent research using an innovative 3D quantitative FISH approach of nuclear remodelling associated with the transition from mononuclear Hodgkin to diagnostic multinuclear Reed-Sternberg cells revealed profound changes in the 3D nuclear organization of telomeres. Analogous 3D telomere dynamics were identified in Hodgkin's lymphoma derived cell-lines and diagnostic patient biopsies. These changes were observed in both, EBV positive and EBV-negative Hodgkin's lymphoma and independent of the age of the patients at presentation. Compared to mononuclear Hodgkin cells, multinuclear Reed-Sternberg cells are characterized by a highly significant increase of telomere aggregates, often composed of very short telomeres, telomere shortening and loss. RS-cells with telomere free "ghost" nuclei are regularly observed. The telomere protecting shelterin complex appears to be disrupted and deregulation of DNA-repair mechanisms is observed. Our findings are consistent with the hypothesis that distinct 3D telomere changes and shelterin disruption represent a common pathogenetic denominator in the generation of Reed-Sternberg cells.

    2010-01-01

    Reed-Muller codes are studied for peak power control in multicarrier code-division multiple access (MC-CDMA) communication systems. In a coded MC-CDMA system, the information data multiplexed from users is encoded by a Reed-Muller subcode and the codeword is fully-loaded to Walsh-Hadamard spreading sequences. The polynomial representation of a coded MC-CDMA signal is established for theoretical analysis of the peak-to-average power ratio (PAPR). The Reed-Muller subcodes are defined in a recursive way by the Boolean functions providing the transmitted MC-CDMA signals with the bounded PAPR as well as the error correction capability. A connection between the code rates and the maximum PAPR is theoretically investigated in the coded MC-CDMA. Simulation results present the statistical evidence that the PAPR of the coded MC-CDMA signal is not only theoretically bounded, but also statistically reduced. In particular, the coded MC-CDMA solves the major PAPR problem of uncoded MC-CDMA by dramatically reducing its PAPR...

    In recent years, serious reed fires occurred in Zhalong Nature Reserve in Heilongjiang Province in China. From 19th to 28th of March 2005, 12 fires occurred in Zhalong Nature Reserve, and the fires spread to Qiqihaer City, Duerberte Mongolian Autonomous County, Lindian County and Daqing City. The burned area was about 18 666 ha. Meteorological factor was the leading factor of its fire environment in Zhalong Nature Reserve, which came into being for a long time. Long-term drought and shortage of rain made the reed and meadow withered and yellow and thus greatly reduced the water content of withered fallen leaves and humus. Much fuel was accumulated and became dry, thus forming the fire environment. Fires in Zhalong Nature Reserve were mainly strong surface fires accompanied by the spread of underground fire. It was extremely easy for reed to burn and spread very quickly. Once a fire broke out, it could spread rapidly to a scene of large fire area, and sometimes it could burn for a long time. Due to lack of correct understanding of the wetland fire and inconvenient wetland traffic, it was unable to find and put out wetland fire in time to save life and property early.

    We describe the first verified nests, eggs, and nestlings of the Nightingale Reed-Warbler (Acrocephalus luscinia), an endangered species endemic to the Mariana Islands, Micronesia. Nest composition, nest dimensions, and eggs were studied on the island of Saipan. Nests were located within three habitat types: upland introduced tangantangan (Leucaena leucocephala) forest, a native mangrove (Bruguiera gymnorrhiza) wetland, and a native reed (Phragmites karka) wetland. Nesting substrates included five native and two introduced tree species and one native reed species. Nests were composed primarily of dry vine stems, needle-like branchlets of ironwood (Casuarina equisetifolia), and tangantangan petioles. Nests were compact to bulky in construction and were secured to a forked arrangement of branches or stems. The background color of eggs ranged from white to cream to ivory-buff. Eggs were spotted, speckled, and blotched with gray, brown, black, and rust colored markings. Clutch size was 2-4, with a mode of two. Hatchlings were altricial with closed eyelids and devoid of natal down with dark gray to black skin. Nestlings examined prior to fledging resembled the adult plumage, except for the lack of the yellow supercilium found in adults. The nests and eggs have some characteristics similar to those of other Acrocephaline warblers found throughout Micronesia and Polynesia.

    Two types of biochars were prepared by pyrolyzing reed straw and municipal sludge at the temperature of 500 degrees C. The structure and properties of biochars were characterized by BET, scanning electron microscope (SEM), energy dispersive spectroscopy (EDS) and fourier transform infrared spectroscopy ( FTIR ). The effects of pH value, adsorption time, temperature and initial concentration of norfloxacin (NOR) on the adsorption behaviors were determined by single factor experiments, which were used to preliminarily discuss adsorption mechanism. The results showed that the adsorption of NOR onto biochars derived from reed straw and municipal sludge could reach 70% and 60% of the total adsorption within 12 h, respectively; the maximum adsorption capacities of the two biochars were 2.13 mg x g(-1) (biochar derived from reed straw) and 2.09 mg x g(-1) (biochar derived from municipal sludge). The quantities of both absorptions increased with the decreasing solution pH. The two adsorption kinetics of NOR onto biochars followed the pseudo second order kinetic equations, and adsorption isotherms fitted well with the Langmuir equations. Adsorption thermodynamics parameters such as Gibbs free energy (AG), enthalpy (AH) and entropy (AS) indicated that the two adsorptions were endothermic reactions. Infrared spectroscopy analysis indicated that oxygen-containing functional groups on biochars provided NOR molecules with adsorptive sites, which facilitated the formation of hydrogen bonds between NOR and the biochars.

    2015-03-01

    The effect of citric acid (CA), rhizosphere acidophilic heterotrophs and/or Fe(II) oxidizing bacteria (Fe(II)OB) on plaque formation and metal accumulation in Phragmites australis L. (common reed) from acid mine drainage (AMD) solution were investigated. Reeds were grown in different hydroponic solutions that contained AMD, CA and/or rhizosphere bacteria for three months. Triplicate experiments were conducted for each experimental condition. Fe(II)OB enhanced the formation of Fe plaque which decreased Fe and Mn uptake in reeds, while it had no significant influence on Al accumulation. CA inhibited the growth of Fe(II)OB, decreased the formation of metal plaque and increased Fe and Mn accumulation in reeds. Acidophilic heterotrophs consumed CA and made the environment more suitable for the growth of Fe(II)OB. Reeds are a good candidate for phytoextraction while CA is a useful chelator to enhance metal uptake in plants. More research may be needed to investigate the influence of CA on microbial community. Further investigations are required to study the effect of CA on phytoremediation of AMD contaminated fields. Copyright © 2014 Elsevier Ltd. All rights reserved.

    2016-09-01

    Full Text Available The thermosolutal instability of compressible Walters' (model B' elastico-viscous rotating fluid permeated with suspended particles (fine dust in the presence of vertical magnetic field in porous medium is considered. By applying normal mode analysis method, the dispersion relation has been derived and solved analytically. It is observed that the rotation, magnetic field, suspended particles and viscoelasticity introduce oscillatory modes. For stationary convection the Walters' (model B' fluid behaves like an ordinary Newtonian fluid and it is observed that the rotation and stable solute gradient has stabilizing effects and suspended particles are found to have destabilizing effect on the system, whereas the medium permeability has stabilizing or destabilizing effect on the system under certain conditions. The magnetic field has destabilizing effect in the absence of rotation, whereas in the presence of rotation, magnetic field has stabilizing or destabilizing effect under certain conditions.

  19. Entretelones de una "estética operatoria" Luis Juan Guerrero y Walter Benjamin

    2009-06-01

    Full Text Available En este artículo se ensaya una aproximación a la labor estético-filosófica del argentino Luis Juan Guerrero (1899-1957, a través de un cotejo de su temprana y productiva recepción de algunos aspectos centrales de la obra de Walter Benjamin. Se intenta mostrar que esta clave de lectura permite un acceso privilegiado a la labor de Guerrero, a la vez que ayuda a construir una imagen más compleja y matizada de la generación intelectual "antipositivista" a la que perteneció. La olvidada obra de Guerrero se compone principalmente de trabajos sobre ética, psicología y estética. Acotaremos nuestra atención a su principal trabajo, y acaso la obra sobre estética más ambiciosa jamás escrita en nuestro país: Estética Operatoria en sus Tres Direcciones. Se muestra en el artículo que la summa estética de Guerrero, si bien expresa con toda claridad las preocupaciones centrales de una generación intelectual marcada por la cultura alemana de entreguerras y por la problemática de la "crisis de la cultura", inscribe, a su vez, una anomalía -benjaminiana-, una inflexión político-materialista, que pone en cuestión la idea frecuente de que la "crisis de la cultura" una y otra vez diagnosticada en aquella época mostró siempre alternativas "espiritualistas" de resolución.This essay deals with the aesthetic-philosophical work of the Argentinean Luis Juan Guerrero (1899-1957, through a consideration of its early and fruitful reception of some central aspects of Walter Benjamin's work. It is shown that this perspective allows a privileged access to Guerrero's work, at the same time that it makes more complex the image of the "anti-positivistic" intellectual generation in Argentina. Guerrero's forgotten work includes principally contributions on ethics, psychology and aesthetics. This essay will pay attention only to his most important work, maybe the most ambitious aesthetic work ever written in Argentina: Operatory Aesthetics in its Three

  11. Representation of Solar Capacity Value in the ReEDS Capacity Expansion Model

    Energy Technology Data Exchange (ETDEWEB)

    Sigrin, B.; Sullivan, P.; Ibanez, E.; Margolis, R.

    2014-03-01

    An important issue for electricity system operators is the estimation of renewables' capacity contributions to reliably meeting system demand, or their capacity value. While the capacity value of thermal generation can be estimated easily, assessment of wind and solar requires a more nuanced approach due to the resource variability. Reliability-based methods, particularly assessment of the Effective Load-Carrying Capacity, are considered to be the most robust and widely-accepted techniques for addressing this resource variability. This report compares estimates of solar PV capacity value by the Regional Energy Deployment System (ReEDS) capacity expansion model against two sources. The first comparison is against values published by utilities or other entities for known electrical systems at existing solar penetration levels. The second comparison is against a time-series ELCC simulation tool for high renewable penetration scenarios in the Western Interconnection. Results from the ReEDS model are found to compare well with both comparisons, despite being resolved at a super-hourly temporal resolution. Two results are relevant for other capacity-based models that use a super-hourly resolution to model solar capacity value. First, solar capacity value should not be parameterized as a static value, but must decay with increasing penetration. This is because -- for an afternoon-peaking system -- as solar penetration increases, the system's peak net load shifts to later in the day -- when solar output is lower. Second, long-term planning models should determine system adequacy requirements in each time period in order to approximate LOLP calculations. Within the ReEDS model we resolve these issues by using a capacity value estimate that varies by time-slice. Within each time period the net load and shadow price on ReEDS's planning reserve constraint signals the relative importance of additional firm capacity.

  12. Educação e infância em alguns escritos de Walter Benjamin

    Directory of Open Access Journals (Sweden)

    Anita Helena Schlesener

    2011-04-01

    Full Text Available Este trabalho pretende refletir sobre alguns escritos de Walter Benjamin sobre educação e infância, expressos também na obra Infância em Berlim por volta de 1900. Benjamin coloca em questão a educação burguesa e suas práticas e reflete sobre o imaginário da criança. Relacionando percepção e conceito, Benjamin apresenta conceitos que inserem a educação no contexto da filosofia da historia. O artigo visa a acentuar a originalidade de um autor que, no contexto da sociedade europeia de 1920 até sua morte por suicídio em 1940, colocou relevantes questões sobre educação e sugeriu novos paradigmas de interpretação, conforme a afirmação de Benjamin, método de montagem, como um mosaico ou uma constelação.

  13. Alfred Walter Campbell and the visual functions of the occipital cortex.

    Science.gov (United States)

    Macmillan, Malcolm

    2014-07-01

    In his pioneering cytoarchitectonic studies of the human brain, Alfred Walter Campbell identified two structurally different areas in the occipital lobes and assigned two different kinds of visual functions to them. The first area, the visuosensory, was essentially on the mesial surface of the calcarine fissure. It was the terminus of nervous impulses generated in the retina and was where simple visual sensations arose. The second area, the visuopsychic, which surrounded or invested the first, was where sensations were interpreted and elaborated into visual perceptions. I argue that Campbell's distinction between the two areas was the starting point for the eventual differentiation of areas V1-V5. After a brief outline of Campbell's early life and education in Australia and of his Scottish medical education and early work as a pathologist at the Lancashire County Lunatic Asylum at Rainhill near Liverpool, I summarise his work on the human brain. In describing the structures he identified in the occipital lobes, I analyse the similarities and differences between them and the related structures identified by Joseph Shaw Bolton. I conclude by proposing some reasons for how that work came to be overshadowed by the later studies of Brodmann and for the more general lack of recognition given Campbell and his work. Those reasons include the effect of the controversies precipitated by Campbell's alliance with Charles Sherrington over the functions of the sensory and motor cortices.

  14. Youth and pedagogy (On the genesis of the thought of Walter Benjamin

    Directory of Open Access Journals (Sweden)

    Lluís BALLESTER BRAGE

    2012-02-01

    Full Text Available The authors analyze the 16 early writings that W. Benjamin wrote between the ages of 19 and 23, all of which relate to educative matters, and where the decisive influence of G. Wyneken is shown. The issues that the young Walter Benjamin addresses are also studied, such as idealism and youth culture, the necessity of reform in schools and universities and also in moral, aesthetic and religious education as well as in juvenile sexuality. However, the most important thing is that in these works one can find the constants that characterize the rest of his production, such as his individualism, his obsession with his own childhood experiences, his contradictions and thematic transitions, his interest in aesthetics and art, the complexity of his work, his agnosticism and his consideration of Judaism as a cultural element, and above all his critical sense and his vocation for criticism which starts to become evident. Somehow in these articles of educative content one can discover many of the constants of what will be the subsequent work of this author.

  15. Walter van den Broeck se utopiese uitdaging aan die globale kapitalisme in Terug naar Walden

    Directory of Open Access Journals (Sweden)

    Andries Visagie

    2012-11-01

    Full Text Available Die sosialistiese simpatieë wat die skryfwerk van die Vlaamse outeur Walter van den Broeck onderlê, skakel hom met die goed ontwikkelde tradisie van sosiaal betrokke literatuur in Vlaandere. Sy roman Terug naar Walden, gepubliseer in 2009, is ’n herbesoek aan die Waldenprojek van die Nederlandse hervormer en skrywer Frederik van Eeden (1860−1932. Van den Broeck gee te kenne dat ’n heroorweging van die sosialistiese ideale wat Van Eeden besiel het om nedersettings in Nederland en die VSA op die been te bring, geregverdig is in die lig van die ekonomiese krisis wat in 2008 deur onbesonne kapitalistiese praktyke veroorsaak is. In Terug naar Walden ontketen Ruler Marsh, die rykste man in die wêreld, ’n globale finansiële krisis in weerwraak teen die kapitalistiese stelsel wat tot die ondergang van sy ouers gelei het. Marsh keer terug na die Kempen in Vlaandere, sy familie se land van herkoms. In ’n Heideggeriaanse bevestiging van die lokale, soos versinnebeeld deur die veldpad, skakel Van den Broeck sy visie van die gemene (die gedeelde oftewel the common, ’n konsep wat teoretici soos Michael Hardt en Antonio Negri in hul Empire-trilogie vanuit die kommunistiese denke gerehabiliteer het, met ’n utopiese siening dat ’n stewiger band met die land en die mense uit die eie kontrei ’n nuttige vertrekpunt mag wees vir die ontwikkeling van lewensvatbare alternatiewe vir die kapitalisme.

  16. Para un concepto de no lineal de Historia. Reflexiones a partir de Walter Benjamin

    Directory of Open Access Journals (Sweden)

    Stefan Gandler

    2011-04-01

    Full Text Available O ponto de partida deste estudo é o mais recente texto de Walter Benjamin, sua tese "Sobre o conceito de história". Benjamin apela para a importância da teologia para o materialismo histórico, com a intenção de superar uma das razões decisivas porque o projeto único da teoria de Marx, em suas interpretações positivistas, não foi entendido com a necessária radicalidade e estava em risco de perder seu poder explicativo e seu impulso revolucionário. A necessidade de olhar para trás, em direção ao que chamamos de passado, é o foco do estudo, e é analisada no nível epistemológico, ontológico e político. O olhar para trás também é necessário porque o passado mostra como todas as atrocidades, que pensamos ter superado, podem voltar a qualquer momento em uma maneira que não podemos imaginar.

His family background was rich in pastoral ministry at home and adventure abroad. Arguably, this background played a part in his decision to serve the Jews of Safed. His life in Palestine entailed much enterprise and hardship as he raised a family, fought disease and set up a mission hospital serving not only the Jewish community but persons of all faiths. His years in Palestine, from 1894 to 1915, were times of peace in the Middle East before the turmoil unleashed by the Great War. Jews from the Diaspora were gaining an increasing foothold in Palestine, their 'Promised Land'. Themes of that era - the rise of Zionism, confrontation between Judaism and evangelical Christianity, conflict between immigrant Jew and Palestinian Arab and the remarkable travels of Lawrence of Arabia were interwoven with the lives of Dr Anderson and his family.

    The theoretical solid-state physicist Walter Kohn was awarded one-half of the 1998 Nobel Prize in Chemistry for his mid-1960's creation of an approach to the many-particle problem in quantum mechanics called density functional theory (DFT). In its exact form, DFT establishes that the total charge density of any system of electrons and nuclei provides all the information needed for a complete description of that system. This was a breakthrough for the study of atoms, molecules, gases, liquids, and solids. Before DFT, it was thought that only the vastly more complicated many-electron wave function was needed for a complete description of such systems. Today, fifty years after its introduction, DFT (in one of its approximate forms) is the method of choice used by most scientists to calculate the physical properties of materials of all kinds. In this paper, I present a biographical essay of Kohn's educational experiences and professional career up to and including the creation of DFT.

  19. Eurydice at Euston?: Walter Benjamin and Marc Augé Go Underground

    Directory of Open Access Journals (Sweden)

    Graeme Gilloch

    2014-01-01

    Full Text Available Taking as its point of departure Walter Benjamin’s repeatedly unsuccessful attempt to give spatial form to his past, this paper suggests that it is perhaps the contemporary French anthropologist, Marc Augé, who provides the most appropriate envisioning of a ‘map of memories’ in his brief writings on the Parisian métro system. For Augé, the labyrinthine subway network constitutes nothing less than a ‘memory machine’ in which lines and station names serve as mnemonics, recalling long-forgotten childhood encounters and experiences. Mirroring the cityscape above, places themselves unexplored, unknown, the serried toponyms of the métro become an incantation summoning forth the shades of the past. As Augé points out, those stations that provide opportunities to change lines are felicitously termed ‘correspondences’, a Baudelairean term that fascinated Benjamin and informed his key historiographical notion of the ‘dialectical image,’ the intersection and mutual illumination of past and present moments. For me, Augé’s highly suggestive reflections bring to mind my own memories of a London childhood around 1970. Looking at the London underground map today, I cannot but see the sites of many past meetings and partings, dots connected by lines forming complex figures, constellations of memory.

    The ancient Egyptians left an impressive artistic legacy documenting many aspects of their society including the existence of dwarfs as highly valued members. In previous publications in the Journal, I discussed dwarfs and skeletal dysplasia in ancient Egypt. In this study, I examined the ancient Egyptian representations of dwarfs of the Walters Art Museum in Baltimore, Maryland. One of the highlights of the collection is a group of five ivory figurines from Predynastic Times (pre 3500-3100 BCE) depicting a couple, a man with a child, and two females. Representations from other periods include ordinary as well as dwarf deities. The dwarf gods, Bes and Ptah, are frequently depicted holding or biting snakes or standing on crocodiles symbolizing their ability to ward off dangers. A couple of statuettes from the Greco-Roman Period that, in contrast to earlier Egyptian Periods, depict harsh physical anomalies, twisted bodies, and facial pain. The artistic impression can be interpreted as either tragic or humorous. The grotesque depiction of dwarfs during the Greco-Roman Period in ancient Egypt is believed to be due to a greater infusion of Hellenistic influence. This study provides a microcosm of the legacy of dwarfs in ancient Egypt and supports the premise that dwarfs were accepted and integrated in the ancient Egyptian society, and with a few exceptions, their disorder was not depicted as a physical handicap.

  2. The Architecture of a Lifetime: Structures of Remembrance and Invention in Walter Benjamin and Aldo Rossi

    2016-05-01

    Full Text Available This article presents the result of research on the influence of Walter Benjamin’s thinking in the work of Italian architect Aldo Rossi (1931–1997. In present-day architectural criticism, Aldo Rossi’s oeuvre still constitutes a rich subject for discussion because of its resistance to easy pinpointing, even if Rossi himself explained his theories and methods of design on numerous occasions. In his writings, among these A Scientific Autobiography, Rossi quotes from a collection of Benjamin’s memoirs: Berlin Childhood around 1900. The architect believes that these short prose pieces express better than anything else what he himself had not been able to explain in his writing. In this paper I intend to show the poignancy of the words Rossi referred to and the implications they had on his architecture by offering close comparisons of Benjamin’s and Rossi’s autobiographical writings. In addition, this study examines how one of Rossi’s most famous architectural artefacts, the ossuary of San Cataldo cemetery at Modena, can be viewed as a coalescence of a Benjaminian thought-image, thereby fortifying the philosopher’s presence in modern architecture.

    Products of Reed-Solomon codes are important in applications because they offer a combination of large blocks, low decoding complexity, and good performance. A recent result on random graphs can be used to show that with high probability a large number of errors can be corrected by iterating...... minimum distance decoding. We present an analysis related to density evolution which gives the exact asymptotic value of the decoding threshold and also provides a closed form approximation to the distribution of errors in each step of the decoding of finite length codes....

    2010-01-01

    Polar codes, introduced by Arikan, achieve symmetric capacity of any discrete memoryless channels under low encoding and decoding complexity. Recently, non-binary polar codes have been investigated. In this paper, we calculate error probability of non-binary polar codes constructed on the basis of Reed-Solomon matrices by numerical simulations. It is confirmed that 4-ary polar codes have significantly better performance than binary polar codes on binary-input AWGN channel. We also discuss an interpretation of polar codes in terms of algebraic geometry codes, and further show that polar codes using Hermitian codes have asymptotically good performance.

    2009-01-01

    To improve error-correcting performance, an iterative concatenated soft decoding algorithm for Reed-Solomon (RS) codes is presented in this article. This algorithm brings both complexity as well as advantages in performance over presently popular sott decoding algorithms. The proposed algorithm consists of two powerful soft decoding techniques, adaptive belief propagation (ABP) and box and match algorithm (BMA), which are serially concatenated by the accumulated log-likelihood ratio (ALLR).Simulation results show that, compared with ABP and ABP-BMA algorithms, the proposed algorithm can bring more decoding gains and a better tradeoffbetween the decoding performance and complexity.

    Liquid hot water (LHW) and alkaline pretreatments of giant reed biomass were compared in terms of digestibility, methane production, and cost-benefit efficiency for electricity generation via anaerobic digestion with a combined heat and power system. Compared to LHW pretreatment, alkaline pretreatment retained more of the dry matter in giant reed biomass solids due to less severe conditions. Under their optimal conditions, LHW pretreatment (190°C, 15min) and alkaline pretreatment (20g/L of NaOH, 24h) improved glucose yield from giant reed by more than 2-fold, while only the alkaline pretreatment significantly (pAlkaline pretreatment achieved 27% higher net electrical energy production than that of non-pretreatment (3859kJ/kg initial total solids), but alkaline liquor reuse is needed for improved net benefit.

    Reed lignocellulose was subjected to a steam explosion pretreatment to obtain a high conversion rate of sugar after subsequent enzymatic hydrolysis using a commercial cellulase mixture. Under conditions of differing temperature (200 °C, 220 °C and 240 °C) and residence time (2, 5, and 8 min), the effect of the pretreatment on the sugar yield from enzymatic hydrolysis was studied. The highest respective reducing sugar and glucose yields were 36.14% and 15.35% after 60-h enzymatic hydrolysis of reed straw that had been pretreated with a steam explosion at 220 °C for 5 min. Fourier transform infrared spectrophotometry (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used in this study to comprehensively investigate the steam explosion-induced changes in the organizational structure and morphological properties of reed straw to analyze the reason for the increased sugar yield from enzymatic hydrolysis after the steam explosion.

    An analytical procedure was developed to simultaneously determine bisphenol S, bisphenol F, bisphenol B, bisphenol A, bisphenol AF, tetrachlorobisphenol A, and tetrabromobisphenol A in reed and Callitrichaceae. Homogenized samples were extracted with acetonitrile and purified using an ENVI™-Carb cartridge followed by an NH2 cartridge. The analytes were separated and quantified by ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The recoveries at three fortified levels in reed and Callitrichaceae were 57-108% and 68-106%, respectively, with relative standard deviations of no more than 15% (n=6). The method limits of quantification and detection for the seven bisphenol analogues were 0.005-0.500μg/kg and 0.002-0.150μg/kg, respectively. This method was used to analyze the seven compounds in ten reed and Callitrichaceae samples collected from Zhejiang, China.

    The protection,restoration and sustainable use are key issues of all the wetlands worldwide.Ecological,agronomic,and engineering techniques have been integrated in the development of a structurally sound,ecologically beneficial engineering restoration method for restoring and utilizing a degraded saline wetland in the western Songnen Plain of China.Hydrological restoration was performed by developing a system of biannual irrigation and drainage using civil engineering measures to bring wetlands into contact with river water and improve the irrigation and drainage system in the wetlands.Agronomic measures such as plowing the reed fields,reed rhizome transplantation,and fertilization were used to restore the reed vegetation.Biological measures,including the release of crab and fish fry and natural proliferation,were used to restore the aquatic communities.The results of the restoration were clear and positive.By the year 2009,the reed yield had increased by 20.9 times.Remarkable ecological benefits occurred simultaneously.Vegetation primary-production capacity increased,local climate regulation and water purification enhanced,and biodiversity increased.This demonstration of engineering techniques illustrates the basic route for the restoration of degraded wetlands,that the biodiversity should be reconstructed by the comprehensive application of engineering,biological,and agronomic measures based on habitat restoration under the guidance of process-oriented strategies.The complex ecological system including reeds,fish and crabs is based on the biological principles of coexistence and material recycling and provides a reasonable ecological engineering model suitable for the sustainable utilization of degraded saline reed wetlands.
