    Science.gov (United States)

    Day, Jonathan F

    2015-12-01

    Richard Floyd Darsie, Jr. (1915-2014) is the 2015 American Mosquito Control Association Memorial Lecture Honoree. He was one of the greatest mosquito taxonomists of the 20th century and died peacefully on April 10, 2014, in Grove City, PA, at the age of 99 after a professional career that spanned eight decades. Dick's broad areas of interest and training made him a versatile scientist, teacher, and researcher. His intense interest in adult and immature mosquito morphology and taxonomy, as well as mosquito distribution and bionomics, started early in his career at two early academic postings: Franklin and Marshall College (1949-54) and the University of Delaware (1954-62). Dick would take his mosquito interests with him to postings and research projects around the world: Nepal, the Philippines, Atlanta, El Salvador, Guatemala, Fort Collins, South Carolina, Argentina, and Florida. His travels and studies would make him an international expert on mosquito taxonomy. Dick's legacy lives on in the hundreds of students from across the globe who learned mosquito identification skills from this world-renowned mosquito taxonomist. All will proudly profess that, "I learned mosquito identification from Dr. Darsie." And that is all that is needed to prove one's credentials in the field, learning the art from the best there is.

More specifically, the National Research Council was asked to identify criteria for evaluating biological indicators, to evaluate methods of indicator development, to provide examples of ndicators that have proven useful, and to identify areas where further research is likely to yield more useful and powerful indicators. In addition, the National Research Council was to examine what aspects of environmental conditions and trends should be monitored.

  11. Ultra light weight jet engine JR100; Chokeiryo jet engine JR100

    Energy Technology Data Exchange (ETDEWEB)

    Matsuki, M. [Nippon Institute of Technology, Saitama (Japan)

    1999-03-20

    As a part of the jet lift V/STOL research by National Aerospace Laboratory, a study of trial manufacture of ultra light weight jet engine JR 100 started in FY 1964. The study was aimed at obtaining a lift engine for VTOL and founding the base for the future jet lift VTOL, and at taking in the results of the jet engine element study accumulated so far and manufacturing an advanced engine. Decided on the use of domestic materials for JR 100, the materials to be used are almost iron-based ones. Through the efforts for weight reduction in structure and processing, a thrust/weight ratio of 10 was realized. At the same time, the production/processing of light weight materials such as titanium alloys was proceeded with, and by adopting the materials to JR 200 system, a thrust/weight ratio of 15 was realized. Together with these, for the purpose of reducing the fuel consumption rate, studies started on fan for lift fan engine and high temperature turbine (an inlet temperature of 1250 degrees C was achieved), to get low noise/high efficiency fan. By the research results, the basis for jet lift VTOL was established, and it became the basis for the development of turbo fan engine FJR 710. (NEDO)

  18. Public memory and national recreation. Politics of memory and cultural practices in republican Barcelona (1931-1936

    Directory of Open Access Journals (Sweden)

    Fernando Sánchez-Costa

    2015-04-01

    Full Text Available The aim of this article is to analyse speeches and commemorative practices in Barcelona during the Second Republic (1931-1936. For this purpose, it uses a wide range of contemporary newspaper and administrative sources as well as national and international bibliography. The author understands that the «public memory» forms part of the «public sphere» in the Habermassian sense, that is to say of the area in which the community discovers and defines itself. With this aim in mind, the author dissects commemorative narratives and praxis so as to identify the ideologically implicit concepts that underlie or are made explicit within them. The concept of «public memory» is defined as a category of sociohistorical analysis. The text analyses the dominant speeches of memory and their links with the prevailing liberal-working class nationalism. It studies the coincidences and differences between these verbal and visual accounts and renaixentista Catalan historiography. At the same time, it is argued that the fundamental tenets of the Catalan historical mind-set, as well as the wish to «redeem the past», enable us to interpret the political behaviour of leaders in this period. The article also makes reference to the importance of citizen-led initiatives for the symbolic configuration of the new tapestry of urban memory.

  20. MILLS B. LANE, JR. AND ENTERPRISE IN A NEW SOUTH

    Directory of Open Access Journals (Sweden)

    Randall L. Patton

    2009-01-01

    Full Text Available For a century, Citizens & Southern Bank was a fixture in Georgia. In 1991, the C&S brand name disappeared in a merger with North Carolina National Bank. This was one of the bittersweet consequences of the slow, confusing swirl of bank deregulation after 1970, when institutions such as C&S simply disappeared, swallowed by the “winners” in the new competitive environment of interstate banking in the 1980s and 1990s. Even earlier, however, the Lane family had ceased to control the bank started by Mills Lane, Sr. in 1891. Mills B. Lane, Jr. was the last member of the Lane family to run C&S. After his retirement in 1973, Mills handpicked his successor and tried to retain some influence, but the bank began slipping away from the Lanes. By the early 80s, a decade before Hugh McColl’s NCNB acquired C&S, Mills Lane, Jr. was deeply alienated from the institution that had been, according to many, “Georgia’s cornerstone bank.”

    Full Text Available In this paper, which has as its basis some of the texts written by the French philosopher Jean-Luc Nancy, I try to discuss some aspects of the formation of the subjects’, or even the citizens’, collective consciousness concerning the nation. For this purpose, I analyze part of the shaping of the Brazilian consciousness (in constant opposition to the American consciousness taking into account a frequent entity in the Western world: the muse(s.

  4. Robert Burns and the Re-making of National Memory in Contemporary Scotland

    Directory of Open Access Journals (Sweden)

    Full Text Available Robert Burns, the eighteenth-century Scottish poet and song writer, continues to maintain a substantial cultural ‘afterlife’ in the twenty first century, both within Scotland and beyond. Achieving cult status in the nineteenth century, the power of Burns as a popular cultural icon remains undiminished. Where the appropriation of Burns as national icon in the nineteenth century was made manifest in statuary, commemorative objects, and painted portraits, the twenty-first century has been marked by the proliferation of the image of Burns in new forms and technologies, with Burns as product and brand logo, museum and heritage attraction, and tourism industry selling point. This recent flourishing of interest and engagement raises questions about why and how an eighteenth-century poet continues to be the object of such extensive cultural elaboration at this time. In approaching this question, some fruitful lines of enquiry are being suggested in recent discussions that have looked at the nineteenth-century Burns as a ‘mobilizing agent in collective memory production’ (Rigney 2011, 81. One such appraisal points to how the construction of Burns in the nineteenth century as an iconic figure of Scottish cultural memory has the potential to ‘be resignified as necessary in subsequent chronological and geographical sites’ (Davis 2010, 14. It is this potential for the resignification of Burns as a symbolic site for the nation’s memory that this paper explores. In pointing to Burns’ representation in a variety of popular forms and in public discourse, the paper examines how a writer comes to be invested and reinvested as the voice and persona of the nation.

  5. Tribute to A. W. Castleman, Jr.

    It is with great pleasure that we join our many colleagues who contributed to this special issue of The Journal of Physical Chemistry A in dedicating it in honor of Professor A. W. “Will” Castleman, Jr. Will is a pioneer in the field of cluster science, and the far-reaching impact of his career is demonstrated by the broad range of topics covered in this issue. This diversity validates Will’s teaching that “fundamental research in cluster science allows you to explore any problem you want”. This ability to extend to other research areas comes because, as Will has shown both rigorously and elegantly, clusters are an intermediate state of matter that bridge the gap between molecular and bulk levels.

  6. Memory and Forgetting on the National Periphery: Marseilles and the Regicide of 1934

    Directory of Open Access Journals (Sweden)

    2010-05-01

    Full Text Available The assassination of the King of Yugoslavia, Alexander Ist by Croatian terrorists during a state visit to Marseilles on 9 October 1934 is commemorated by a modest plaque on the Canebière and a little known monument outside the Préfecture. Although the histories of the period cite the event in passing, it is treated as a footnote in the political history of France and has been all but erased from the memory of the city. While there are good reasons for forgetting the episode – regicide does no favours for the reputation of a host nation or city and the French Foreign Minister Louis Barthou was accidentally shot by the French police – the double killing had multiple ramifications for France's interior and foreign affairs during the rise of fascism in Europe. It advanced the career of future Vichy Prime Minister Pierre Laval, who replaced Barthou as Foreign Minister, while French efforts to contain the threat of German expansionism by forging alliances with the Central European powers died with Barthou; King Alexander Ist's successor moved Yugoslavia into the camp of the Axis powers. Geopolitically, the system of collective security forged at Versailles collapsed in the wake the assassination. The incident in Marseilles highlights political tensions in France in the troubled inter-war years leading up to the emergence of the Front Populaire. It reveals the memorial agencies of core and periphery engaged in a struggle over the rights to remembrance. Above all, it poses the problem of the preservation of peripheral and traumatic episodes in collective memory and suggests that political violence constitutes a social periphery of its own, contributing to Marseille's "mauvaise réputation" as the French capital's negative, meridional 'other'.

    brings up several hundred abstracts. He is remembered warmly by his departmental colleagues. R. K. Honeycutt writes: Those of us who overlapped with Ben at Indiana have only good memories about a good friend. He was a fine stellar astronomer who I remember most fondly from our lunchtime conversations. We talked about astronomy, politics, university issues, the arts, and human development/human nature. With Ben the conversation was always about ideas, not events or people. He was a scholar in the best Univ tradition--I learned a lot from Ben about being part of a University community. His interests remained focused on cool giant stars, like VV Cephei, but moved to the study of systems where the radioactive element technetium could be identified in the spectrum. This observation, first made by Paul Merrill, proved that nuclear transformations involving trans-iron peak elements were taking place in stars, and was a keystone of the theory of nucleosynthesis. Nucleosynthesis and stellar structure were the main fields of his research career. In 1977, Ben joined the faculty of Howard University. Shortly before his departure from Bloomington, IN, he told me that the new move would mean less time for research, and more emphasis on teaching, services, and efforts to bring more African Americans into scientific careers. Ben was only the second African American PhD in astronomy, and felt a responsibility to increase that number and to improve educational opportunities generally for the African Americans. He had been involved with the National Science Teacher's Association's (ASTA) Elementary School Science Program when he was at Indiana. At Howard, he was principal investigator on a NASA grant which led to the development of research and teaching facilities for astronomy. The grant supported both colleagues and students who were able to carry out summer research projects at Goddard Space Flight Center. One of the Howard students supported by this grant, Professor Araya Asfaw, is now

    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.

    Pollution from mining activities is a global environmental concern, not limited to areas of current resource extraction, but including a broader geographic area of historic (legacy) and abandoned mines. The pollution of surface waters from acid mine drainage is a persistent problem and requires a holistic and sustainable approach to addressing the spatial and temporal complexity of mining-specific problems. In this paper, we focus on the environmental, socio-economic, and legal challenges associated with the concurrent activities to remediate a coal mine site and to develop a national memorial following a catastrophic event. We provide a conceptual construct of a socio-ecological system defined at several spatial, temporal, and organizational scales and a critical synthesis of the technical and social learning processes necessary to achieving sustainable environmental remediation. Our case study is an example of a multi-disciplinary management approach, whereby collaborative interaction of stakeholders, the emergence of functional linkages for information exchange, and mediation led to scientifically informed decision making, creative management solutions, and ultimately environmental policy change.

    Jokipii, Jack Randolph

    2004-12-01

    Professor Leverett Davis Jr., Professor of theoretical physics at the California Institute of Technology, died on June 15, 2003 after a long illness. He was 89 years old. He contributed many important ideas and concepts to theoretical astrophysics and was a pioneer in the in situ scientific exploration of space using observations from spacecraft. Davis was born in Elgin, Illinois on March 3, 1914, the eldest of four children of Louis Leverett Davis and Susan Gulick Davis. His parents moved several times as he grew up because his father, a mining engineer, became involved in different mining operations in the American West. Leverett married Victoria Stocker in June 1943. They had two children who died in childhood and subsequently adopted a son, Jeffrey. His wife and son survive him. Davis's early education was rather fractured and uneven because of the many family moves, with periods of home schooling alternating with regular school. His high school education was, on the other hand, reasonably normal. It was while in high school that he decided that he wanted to do physics or mathematics. He went on to earn his Bachelor of Science degree at Oregon State College in 1936, after which he started graduate studies at the California Institute of Technology, to pursue a graduate degree in physics. His advisor was William V. Houston and Davis received his PhD in 1941 for a thesis on electrical properties in nerves. He briefly entertained the idea of changing to work in biophysics. During World War II, Davis became an integral member of the Caltech project for rockets, which developed a number of different types of rockets used in the war. As a result of this war work, Davis wrote a book on Exterior Ballistics, published by Van Nostrand in 1958. He joined the faculty at the California Institute of Technology in 1946, after several years on campus as an instructor. In all, he taught there for nearly four decades before retiring as Professor of Theoretical Physics in 1981

    Osterbrock, Donald E.

    2003-12-01

    Ernest H. Cherrington, Jr., a long-time member of the AAS, died in San Jose, California on 13 July 1996, following a long illness. He had a short but active career as a research astronomer at Perkins Observatory at Ohio Wesleyan University in Delaware, Ohio before World War II, in which he served as an officer in the Army Air Force. After the war ended he turned to full-time teaching and administration at the University of Akron, and then at Hood College in Frederick, Maryland. Ernest was born on 10 September 1909 in Westerville, Ohio, where his father, Ernest H. Cherrington, Sr., was a leader in the temperance movement and publisher of "American Issue", a Prohibitionist magazine. Ernest Jr.'s mother, Betty Clifford (née Denny) Cherrington, was a homemaker. He was an outstanding student in high school and at Ohio Wesleyan University, which he entered in 1927. The little university's Perkins Observatory with its 69-inch reflector, briefly the second largest telescope in the United States, had just been built and gone into operation. After graduating with a BA magna cum laude in astronomy in 1931, Ernest stayed on one more year and earned his MS with a thesis on the motion of material in the tail of Comet Morehouse, supervised by Nicholas T. Bobrovnikoff. In 1932 Ernest entered the University of California at Berkeley as a graduate student, with a one-year teaching assistantship in the Astronomical Department. This was followed by a two-year Lick Observatory Fellowship. In June 1933 he married Ann McAfee Naylor, who had been a classmate at Delaware High School and Ohio Wesleyan. Ernest did his PhD thesis on spectrophotometry of the Mg I b lines in the solar spectrum, using a high-resolution grating spectrograph on the Berkeley campus, designed by C. Donald Shane, his adviser. In this thesis, Ernest tested and improved the then current theory of strong absorption lines in stellar atmospheres. He also spent several short periods at Lick Observatory on Mount Hamilton

    traditions. Earlier in 1971-72, Ray served as Program Officer for Stars and Stellar Evolution in the Astronomy Section of the National Science Foundation. Ray was one of the three "originators" of "The Inspiration of Astronomical Phenomena" (INSAP) Conferences. These conferences provide scholarly discussions on the many and variegated cultural impacts of the perceptions about the day- and night-time sky, thus providing a forum for a broad sampling of artists, historians, philosophers, and scientists to get together, compare notes, and ask questions of one another. The INSAP Conferences have taken place near Castel Gandolfo Italy, on the island of Malta, near Palermo Italy, and at Oxford University in England. Ray's scholarship also was manifest in his activities as editor. For some years in the 1990s, he edited two astronomy journals, The Astronomy Quarterly and Vistas in Astronomy. Raymond E. White, Jr., is survived by his wife Ruby E. (nee Fisk), his high school sweetheart at Heidelberg High in Germany. Their children include Raymond E. White III (Professor of Physics and Astronomy at the University of Alabama, Tuscaloosa), Kathleen M. (White) Wade, and Kevin D. White. Ray was proud of two beautiful granddaughters, Charlotte R. Wade and Sarah E. Wade. Ray was proud of his early role with Steward Observatory Director Bart Bok in the commissioning of the "90-inch" reflector at the University of Arizona site on Kitt Peak in 1969. He built the direct camera, and was invited by his close friend Bok to share the "first light" of this telescope, now renamed the Bok 2.3-m telescope. When Professor Bok passed away, the astronomy magazine Sky & Telescope invited Ray to write an article which was entitled "Bart J. Bok (1906-83): Personal Memoir from a Grandson." (Bok mentored Ivan R. King, who was Ray's thesis advisor.) In his concluding remarks, Ray wrote, "The aspect of Bart J. Bok I will miss the most is his exuberance for the art of astronomy." We will also miss greatly this

    Dr. Edward W. Burke Jr. passed away on June 15, 2011, after suffering a heart attack. Dr. Burke devoted his professional life to the research and teaching of physics and astronomy at King College in Bristol, Tennessee. Edward W. Burke, Jr., was born in Macon, Georgia, on September 16, 1924. He was a Navy veteran, having been commissioned as an ensign in 1944. He served in the Pacific near the end of World War II. He proceeded to complete his undergraduate degree in mathematics from Presbyterian College in 1947 and pursued the M.S. and Ph.D. in physics (1949 and 1954, respectively) at the University of Wisconsin. Under the direction of Professor Julian Mack, his thesis was titled "Isotope Shift in the Spectra of Boron." Although he did research in atomic spectra in the early part of his career, his interest in astronomy and variable stars in particular were his primary interests during his long academic career. Dr. Burke began his illustrious career at King College in 1949. He initiated the astronomy program there in 1950, included constructing a 12.5 inch Newtonian telescope, homemade as was most everything in those days. Many of his students learned about photometry at the Burke Observatory on the college campus. Burke was known for his trips to the Kitt Peak and Lowell observatories accompanied by undergraduate students on his trips, all of which were made by automobile which he preferred over flying. His initial interest in Ap stars later broadened into variable and especially eclipsing binary stars. His motivation was maintained by his desire to have his students experience basic research and to spark their interest in advanced degrees. Numerous students achieved advanced science and medical degrees because of Burke's encouragement and mentoring. In 1959, Dr. Burke was awarded a Fulbright professorship and traveled to Chile where he taught physics for a year in the Engineering School at the University of Chile in Santiago. He worked to establish a physics

    Mount Rushmore National Memorial is located in the east-central part of the Black Hills area of South Dakota and is challenged to provide drinking water to about 3 million annual visitors and year-round park personnel. An environmental concern to water resources within Mount Rushmore National Memorial has been the annual aerial fireworks display at the memorial for the Independence Day holiday during 1998–2009. A major concern of park management is the contamination of groundwater and surface water by perchlorate, which is used as an oxidizing agent in firework displays. A study by the U.S. Geological Survey, in cooperation with the National Park Service, was completed to characterize the occurrence of perchlorate and selected metals (constituents commonly associated with fireworks) in groundwater and surface water within and adjacent to Mount Rushmore National Memorial during 2011–15. Concentrations of perchlorate and metals in 106 water samples (collected from 6 groundwater sites and 14 surface-water sites) and 11 soil samples (collected from 11 soil sites) are reported.Within the Mount Rushmore National Memorial boundary, perchlorate concentrations were greatest in the Lafferty Gulch drainage basin, ranging from less than 0.20 to 38 micrograms per liter (μg/L) in groundwater samples and from 2.2 to 54 μg/L in surface-water samples. Sites within the Starling Gulch drainage basin also had some evidence of perchlorate contamination, with concentrations ranging from 0.61 to 19 μg/L. All groundwater and surface-water samples within the unnamed tributary to Grizzly Bear Creek drainage basin and reference sites outside the park boundary had concentrations less than 0.20 μg/L. Perchlorate concentrations in samples collected at the 200-foot-deep production well (Well 1) ranged from 17 to 38 μg/L with a median of 23 μg/L, whereas perchlorate concentrations in samples from the 500-foot-deep production well (Well 2) ranged from 2.1 to 17 μg/L, with a median of 6

A study by the U.S. Geological Survey, in cooperation with the National Park Service, was completed to characterize the occurrence of perchlorate and selected metals (constituents commonly associated with fireworks) in groundwater and surface water within and adjacent to Mount Rushmore National Memorial during 2011–15. Concentrations of perchlorate and metals in 106 water samples (collected from 6 groundwater sites and 14 surface-water sites) and 11 soil samples (collected from 11 soil sites) are reported.Within the Mount Rushmore National Memorial boundary, perchlorate concentrations were greatest in the Lafferty Gulch drainage basin, ranging from less than 0.20 to 38 micrograms per liter (μg/L) in groundwater samples and from 2.2 to 54 μg/L in surface-water samples. Sites within the Starling Gulch drainage basin also had some evidence of perchlorate contamination, with concentrations ranging from 0.61 to 19 μg/L. All groundwater and surface-water samples within the unnamed tributary to Grizzly Bear Creek drainage basin and reference sites outside the park boundary had concentrations less than 0.20 μg/L. Perchlorate concentrations in samples collected at the 200-foot-deep production well (Well 1) ranged from 17 to 38 μg/L with a median of 23 μg/L, whereas perchlorate concentrations in samples from the 500-foot-deep production well (Well 2) ranged from 2.1 to 17 μg/L, with a median of 6

    In order to face the challenges in healthcare this century, it is essential that surgeons understand modern leadership principles. One of the greatest leaders in history was Dr. Martin Luther King, Jr., who provides a shining example of level-5 leadership for us to study. The study of leadership principles of great leaders can provide us with practical methods of conflict resolution as well as inspiration to keep us engaged and focused. As leaders of the medical community, we face numerous challenges, including discovering and implementing new treatments for disease, providing care for the indigent, overcoming educational challenges such as incorporating the ACGME Core Competencies into our surgical training and promoting diversity in education. Achieving these goals is often hindered by the environment in which we labor-nearly 50 million are uninsured, the rising cost of medical care is currently at 16% of the GNP, and reimbursement rates are falling-which makes the practice of surgery a significant challenge. Effective leadership will be paramount in achieving these goals. In this editorial, which summarizes a presentation given to the Surgical Section of the annual National Medical Association meeting, five important leadership principles that are important for surgeons have been selected and related to the outstanding leadership of Dr. Martin Luther King, Jr.

  1. Cultural Memory Inscribed in the Skin: Symbols of Nation as Tattoo Art in New Zealand

    Directory of Open Access Journals (Sweden)

    2014-11-01

    Full Text Available In New Zealand there is a strand of cultural memory popularly known as 'kiwiana'. The term embraces everyday popular cultural practices - beach activities in summer, food rituals  - as well as an array of vintage artefacts.  The latter are locally manufactured items originating mainly in the 1940s-50s, when import restrictions limited the availability of household goods.  Local makers created products for the domestic market, for instance grocery items (and their logo-bearing containers, household crockery and toys. Those items, intrinsically representations of white (pakeha culture, are fondly recalled by the baby boomers, and have become popular collectibles.  Images of the same items have now become prevalent as decorative motifs on home wares and clothing.Recently a further celebratory strand of kiwiana has now appeared: the inscription of its motifs as extensive permanent skin tattoos. While Maori have always practiced meaningful skin tattoo, and whilst body tattoos in general have joined the realm of fashion, this is something new.  Here we see a recasting of the kiwiana images of popular cultural memory, now drawn onto the body.  One wearer of such a tattoo, a 26 year old plumber, said 'I love New Zealand. I am very proud of who we are and I wouldn't change being a kiwi for the world'. His design, a map of New Zealand on his back in filled with kiwiana items, shows his personal subscription to the populist representations that are utilised as apolitical definition of kiwi­ ness.  Kiwiana tattoo as a growing everyday practice is the focus of this paper.

    Community involvement is not just one facet of the new Martin Luther King, Jr., General Hospital's existence. It is the mainstream from which all other activities flow. In addition to meeting the conventional needs of a conventional hospital staff with the core collection of texts and journals, this library goes one step further. It acts as a resource for its community health workers, dietitians, and nurses in their various outreach programs. It serves as a stimulus for the high school or community college student who may be curious about a health career. It also finds time to provide reading material for its patients.

  4. Possessing History and American Innocence: James Baldwin, William F. Buckley, Jr., and the 1965 Cambridge Debate

    Directory of Open Access Journals (Sweden)

    Daniel Robert McClure

    2016-12-01

    Full Text Available The 1965 debate at Cambridge University between James Baldwin and William F. Buckley, Jr., posed the question: “Has the American Dream been achieved at the Expense of the American Negro?” Within the contours of the debate, Baldwin and Buckley wrestled with the ghosts of settler colonialism and slavery in a nation founded on freedom and equality. Framing the debate within the longue durée, this essay examines the deep cultural currents related to the American racial paradox at the height of the Civil Rights movement. Underscoring the changing language of white resistance against black civil rights, the essay argues that the Baldwin and Buckley debate anticipated the ways the U.S. would address racial inequality in the aftermath of the civil rights era and the dawn of neoliberalism in the 1970s.

  5. A new nearby PWN overlapping the Vela Jr SNR

    2011-01-01

    PSR J0855-4644 is an energetic pulsar (Edot = 1.1x10^36 erg/s, P=65 ms) discovered near the South-East rim of the supernova remnant (SNR) RX J0852.0-4622 (aka Vela Jr) by the Parkes Multibeam Survey. The position of the pulsar is in spatial coincidence with an enhancement in X-rays and TeV gamma-rays, which could represent its pulsar wind nebula (PWN). We have revealed with an XMM-Newton observation the X-ray counterpart of the pulsar together with a surrounding extended emission thus confirming the suggestion of a PWN. The comparison of the absorption column density derived in X-rays from the pulsar with 12CO observations (tracing the dense gas) is used to derive an upper limit to the distance of the pulsar (d< 900 pc) and to discuss a possible association of the pulsar with the Vela Jr SNR. This new distance estimate implies that the pulsar is nearby and could therefore significantly contribute to the observed spectrum of cosmic-ray leptons (e-/e+).

    Ralph Robert Robbins, Jr., died on 2 December 2005, in Kyle, Texas. His wife, Maria Elena Robbins, his daughters Julia Robbins Kelso and Stephanie Juarez Balles, his son Matthew Juarez, and five grandchildren survive him. Bob was on the faculty at the University of Texas from 1968 until his retirement in 2003. Bob was born in Wichita, Kansas, on 2 September 1938, the only son of Mildred and Ralph Robert Robbins, Sr. Guided by his high school's policy to provide a practical education to children of working-class parents, Bob began high school with a heavy dose of vocational courses until the results of a test indicated his special talent in mathematics. He was awarded a full scholarship to Yale University, graduating magna cum laude in mathematics in 1960. He won the Warner Prize in Mathematics at Yale that year. He received his Ph.D. in 1966 with a dissertation entitled "The Triplet Spectrum of Neutral Helium in Expanding Nebulae" from the University of California at Berkeley. His interest in college teaching was ignited at this time through summer teaching positions at San Mateo California Junior College and the Ohio State University. Following a year at Texas as a McDonald Observatory Post-doctoral Fellow, Bob taught for a year in the physics department of the University of Houston before returning to the University of Texas at Austin as an Assistant Professor of Astronomy in 1968. He was promoted to Associate Professor in 1972. Bob's research in the early 1970s on theoretical studies of helium was of vital importance to astronomers for over three decades. These pioneering calculations became vital to observational astronomers in the mid-1990s as interest grew in the primordial helium produced by the Big Bang. Bob's interest and influence in education was international in scope. In the summers 1968-1970, he was a government consultant in Mathematics in East Pakistan (now Bangladesh). He consulted with the government that was preparing a master plan for technical

    Willson, Lee Anne; Struck, Curtis

    2011-12-01

    Our colleague and collaborator George Hamilton Bowen, Jr., passed away November 1, 2009 in Ames, Iowa. George was born June 20, 1925 in Tulsa, Oklahoma to George and Dorothy (Huntington) Bowen. He married Marjorie Brown June 19, 1948 in Redondo Beach, California; they had five children, with eight grandchildren and five great-grandchildren at the time of his death. George H. Bowen's third or perhaps his fourth career was in astronomy. He was drafted into the navy in 1944, at the end of his first year as a student at Caltech, and ended his war-time service as an electronic technician on the aircraft carrier Shangri-La. He later said "In just nine months, starting from scratch (Ohm's law!), we learned an amazing amount - not by memorization, of course, but by study and real understanding of the basic function of the most advanced AC circuits then being used for instrumentation, measurements, communications, control systems, and much more." He gained a confidence that he could quickly and accurately diagnose and solve technical problems that stood him well in future work. One accomplishment he took particular pride in was figuring out how the radar control used cams and gears to solve the trigonometry for accurate pointing. He also described how the captain was alarmed when weather conditions changed so that refraction no longer showed them distant, small boats around the curvature of Earth. After the war, George Bowen returned to undergraduate and eventually graduate study at Caltech, where he was recruited to the biophysics research group headed by future Nobel Laureate Max Delbrück. George often described his joy in working with these first-rate scientists and finding himself accepted as a part of the effort. He finished his BS with honors in 1949 and his PhD in 1953 with a thesis on "Kinetic Studies on the Mechanism of Photoreactivation of Bacteriophase T2 Inactivated by Ultraviolet Light" involving work with E Coli. This work was supported by grants from the U

    2014-03-01

    William T. Carpenter Jr has had a major impact on the design and conduct of clinical trials in schizophrenia. His contributions range from the decisive evaluation of the efficacy of hemodialysis to the development of novel approaches to evaluate new treatments for cognitive impairments and negative symptoms. He has developed innovative dosage reduction strategies. He has led efforts to focus drug development on those illness components that are not responsive to antipsychotic treatment. He has emphasized throughout his career the use of translational science to provide the conceptual framework for clinical trial interventions. This article reviews highlights of his many contributions, with an emphasis on 3 areas: (1) dosage reduction studies; (2) the use of the domains of psychopathology to identify drug development targets; and (3) the use of translational science to guide new drug development.

    2015-08-01

    Full Text Available In this essay I reassess the complexity of the convergence between electronic music and media practices in Rome in the 1950s and 1960s, through the reconstruction of the experience of composer Gino Marinuzzi Jr (1920-96. His engagement with technology as a structuring device of compositional processes is fundamental and inescapable, and brings to the fore crucial issues of ‘applied’ music’s troublesome reputation in the Italian cultural discourse. In reviewing Marinuzzi’s biography over the period 1949-75, my goal is to exemplify the key phases of this transitional period in Italian music history, in which technology, through the spreading of media and their increasing importance in cultural representations, came to constitute a new value of musical activity and at the same time renewed old questions concerning music’s aesthetic autonomy.

    Timothy Pendleton McCullough Jr., 93, a retired research physicist who was a pioneer in the measurement of microwave radiation from planetary surfaces, died of cardiac arrest on 19 November 2004, at Inova Fairfax Hospital. He lived in Springfield, VA. McCullough, who was principally a radio astronomer, published 22 scientific research papers while working in the Atmosphere and Astrophysics Division of NRL, from 1946 until his retirement in 1975. He spent the early part of his career in planetary observation and was among the first in his field to use radio astronomy to measure the surface temperature of Venus. He also studied Mars and Jupiter. Later, his interest turned to supernovas, galaxies and solar flares. He was an emeritus member of the American Astronomical Society and a member of the Sigma Xi Scientific Research Society. McCullough was born on 9 December 1910 in Vardaman, Mississippi. His father, Timothy P. McCullough, was a farmer and bookkeeper. His mother, Annie W. McCullough, was a homemaker. Timothy McCullough, Jr.'s parents, as well as two sisters and a brother, are deceased. McCullough graduated from the University of Mississippi in Oxford in 1936 and received a master's degree in physics from North Carolina State University in Raleigh. He taught physics and aviation navigation before entering the Navy during World War II. He instructed Russian sailors on anti-submarine warfare. McCullough left the Navy at the end of the war, but continued to serve in the Naval Reserve. He was recalled to active duty during the Korean War and was stationed at Potomac River Naval Command, where he wrote technical documents on electronic warfare systems. McCullough retired from the Naval Reserve in 1969 with the rank of commander. He was a charter member of First Baptist Church in Springfield and a former deacon and Sunday school teacher at First Baptist Church in Alexandria. Survivors include his wife of 63 years, Virginia Ball McCullough of Springfield; three

    Dr. Basil A. Pruitt Jr., a consummate clinical and translational surgeon-scientist, has been spent over half a century at the forefront of an advancing standard of burn care. Commanding the US Army Institute for Surgical Research in San Antonio, he trained generations of leading burn clinicians and allied scientists. At his direction, there were forged discoveries in resuscitation from shock, treatment of inhalation injury, control of burn-related infections, prevention of iatrogenic complications, and understanding the sympathetic, endocrine, and immune responses to burn injury. Most consequentially, this team was among the first recognize and define alterations in the basal metabolic rate and thermoregulation consequent to burn injury. These investigations prompted groundbreaking insights into the coordinated nervous, autonomic, endocrine, immune, and metabolic outflows that a severely-burned patient uses to remain alive and restore homeostasis. Marking his scientific consequence, many of his reports continue bear fruit when viewed through a contemporary lens. This paper summarizes some of the major findings of his career thus far, and is intended to complement a Festschrift recently held in his honor. Not applicable.

    Before the discoveries of John Call Dalton, Jr., MD (1824-1889), innervation of laryngeal muscles, long-term effects of cerebellar lesions, and consequences of raised intracranial pressure were poorly understood. Dalton discovered that the posterior cricoarytenoid muscles adducted the vocal cords during inspiration. He confirmed Flourens' observations that acute ablation of the cerebellum of pigeons caused loss of coordination. Dalton observed that properly cared for pigeons gradually recovered "coordinating power." Dalton observed that prolonged raised intracranial pressure caused tachycardia and then fatal bradycardia in dogs. Before Dalton published his photographic atlas of the human brain, neuroanatomy atlases were sketched by Europeans and imported into the United States. Dalton's atlas of the human brain contained precise photographs of vertical and horizontal sections that equal modern works. Before Dalton introduced live demonstrations of animals, physiology was taught by recitation of texts only. Dalton was the first American-born professor to teach physiology employing demonstrations of live animals operated on under ether anesthesia. He wrote an essay advocating experimentation on animals as the proper method of acquiring knowledge of function and that humane animal experimentation would ultimately improve the health of man and animals. His eloquent advocacy for humane experimental physiology quelled attacks by contemporaneous antivivisectionists. Dalton was America's first experimental neurophysiologist.

    Full Text Available Information regarding the echinoids in this dataset is based on the Agassiz Trawl (AGT and epibenthic sledge (EBS samples collected during the British Antarctic Survey cruise JR275 on the RRS James Clark Ross in the austral summer 2012. A total of 56 (1 at the South Orkneys and 55 in the Eastern Weddell Sea Agassiz Trawl and 18 (2 at the South Orkneys and 16 in the Eastern Weddell Sea epibenthic sledge deployments were performed at depths ranging from ~280 to ~2060 m. This presents a unique collection for the Antarctic benthic biodiversity assessment of an important group of benthic invertebrates. In total 487 specimens belonging to six families, 15 genera, and 22 morphospecies were collected. The species richness per station varied between one and six. Total species richness represents 27% of the 82 echinoid species ever recorded in the Southern Ocean (David et al. 2005b, Pierrat et al. 2012, Saucède et al. 2014. The Cidaridae (sub-family Ctenocidarinae and Schizasteridae are the two most speciose families in the dataset. They comprise seven and nine species respectively. This is illustrative of the overall pattern of echinoid diversity in the Southern Ocean where 65% of Antarctic species belong to the families Schizasteridae and Cidaridae (Pierrat et al. 2012.

    1982-07-01

    The Ashton Quadrangle, Idaho, Montana, and Wyoming, was evaluated to identify and delineate areas containing environments favorable for uranium deposits, using criteria developed for the National Uranium Resource Evaluation program. General surface reconnaissance, radiometric traverses, and geochemical sampling were carried out in all geologic environments within the quadrangle. Aerial radiometric data were evaluated, and anomalies were examined in the field. Fourteen uranium occurrences were noted in the study area. Only one environment, the phosphorites of the Permian Phosphoria Formation, is considered favorable for uranium deposition. The unfavorable environments include: limestones, sandstones, coal and carbonaceous shales, volcanics, Precambrian metamorphics, and Tertiary basins. Unevaluated areas include the John D. Rockefeller Jr. Memorial Parkway and Yellowstone and Grand Teton National Parks, where park service regulations prohibit detailed investigations.

    2008-03-01

    Trained as an engineer and a chiropractor, William D. Harper, Jr. made his career in the healing arts as instructor, writer and president of the Texas Chiropractic College (TCC). A native of Texas who grew up in various locales in the Lone Star State, in Mexico and in the Boston area, he took his bachelor's and master's degree in engineering in 1933 and 1934 from the Massachusetts Institute of Technology, and his chiropractic degree at TCC in 1942. Dissatisfied with the "foot-on-the-hose" concept of subluxation syndrome (D.D. Palmer's second theory), Dr. Harper studied and wrote about aberrant neural irritation as an alternative explanation for disease and for the broad clinical value he perceived in the chiropractic art. In this he paralleled much of D.D. Palmer's third theory of chiropractic. His often reprinted textbook, Anything Can Cause Anything, brought together much of what he had lectured and written about in numerous published articles. He was well prepared for the defense of chiropractic that he offered in 1965 in the trial of the England case in federal district court in Louisiana. The case was lost when the court ruled that the legislature rather than the judiciary should decide whether to permit chiropractors to practice, but Harper's performance was considered excellent. He went on to guide the TCC as president from 1965 through 1976, its first 11 years after relocating from San Antonio to Pasadena, Texas. Harper built the school - its faculty, staff and facilities - from very meager beginnings to a small but financially viable institution when he departed. Along the way he found fault with both chiropractic political camps that vied for federal recognition as the accrediting agency for chiropractic colleges in the United States. Dr. Bill Harper was a maverick determined to do things his way, and in many respects he was successful. He left a mark on the profession that merits critical analysis.

  3. Lynn White Jr. and the greening-of-religion hypothesis.

    Science.gov (United States)

    Taylor, Bron; Van Wieren, Gretel; Zaleha, Bernard Daley

    2016-10-01

    Lynn White Jr.'s "The Historical Roots of Our Ecologic Crisis," which was published in Science in 1967, has played a critical role in precipitating interdisciplinary environmental studies. Although White advances a multifaceted argument, most respondents focus on his claim that the Judeo-Christian tradition, especially Christianity, has promoted anthropocentric attitudes and environmentally destructive behaviors. Decades later, some scholars argue contrarily that Christianity in particular and the world's predominant religions in general are becoming more environmentally friendly, known as the greening-of-religion hypothesis. To test these claims, we conducted a comprehensive review of over 700 articles-historical, qualitative, and quantitative-that are pertinent to them. Although definitive conclusions are difficult, we identified many themes and dynamics that hinder environmental understanding and mobilization, including conservative theological orientations and beliefs about the role of divine agency in preventing or promoting natural events, whether the religion is an Abrahamic tradition or originated in Asia. On balance, we found the thrust of White's thesis is supported, whereas the greening-of-religion hypothesis is not. We also found that indigenous traditions often foster proenvironmental perceptions. This finding suggests that indigenous traditions may be more likely to be proenvironmental than other religious systems and that some nature-based cosmologies and value systems function similarly. Although we conclude White's thesis and subsequent claims are largely born out, additional research is needed to better understand under what circumstances and communication strategies religious or other individuals and groups may be more effectively mobilized to respond to contemporary environmental challenges. © 2016 Society for Conservation Biology.

  4. The Manuel Lujan Jr. Neutron Scattering Center (LANSCE) experiment reports 1993 run cycle. Progress report

    1995-06-01

    This year the Manuel Lujan Jr. Neutron Scattering Center (LANSCE) ran an informal user program because the US Department of Energy planned to close LANSCE in FY1994. As a result, an advisory committee recommended that LANSCE scientists and their collaborators complete work in progress. At LANSCE, neutrons are produced by spallation when a pulsed, 800-MeV proton beam impinges on a tungsten target. The proton pulses are provided by the Clinton P. Anderson Meson Physics Facility (LAMPF) accelerator and a associated Proton Storage Ring (PSR), which can Iter the intensity, time structure, and repetition rate of the pulses. The LAMPF protons of Line D are shared between the LANSCE target and the Weapons Neutron Research (WNR) facility, which results in LANSCE spectrometers being available to external users for unclassified research about 80% of each annual LAMPF run cycle. Measurements of interest to the Los Alamos National Laboratory (LANL) may also be performed and may occupy up to an additional 20% of the available beam time. These experiments are reviewed by an internal program advisory committee. This year, a total of 127 proposals were submitted. The proposed experiments involved 229 scientists, 57 of whom visited LANSCE to participate in measurements. In addition, 3 (nuclear physics) participating research teams, comprising 44 scientists, carried out experiments at LANSCE. Instrument beam time was again oversubscribed, with 552 total days requested an 473 available for allocation.

  10. Landscape, historic memory and national identity in the beginnings of the policy nature conservation in Spain: from Covadonga to San Juan de la Peña

    Directory of Open Access Journals (Sweden)

    Jacobo García Álvarez

    2013-08-01

    Full Text Available This article reflects on the concept of “national landscape” and on the importance of identity symbolic values in the beginning of landscape and nature conservation policy in Spain. The emblematic case of the Montaña de Covadonga (the first National Park created in Spain is examined in more detail. The paper is divided into three main sections. The first one raises some theoretical and general considerations on the role of identity symbolic values within the first steps of nature conservation policies in Spain and other national contexts. Secondly, the cultural-historic processes and discourses which converted the Montaña de Covadonga landscape into a Spanish national symbol and into a site of memory, leading to its declaration as a National Park in 1918, are reviewed. The third section examines the ideological identity disputes and controversies concerning the creation of that National Park, some of which led to the declaration of the Sitio Nacional del Monte de San Juan de la Peña in 1920. The article approaches the creation of the first Spanish Natural Parks as a part of the nationalization policies inspired by the concerns of the “Regeneracionismo”. More precisely, the beginning of natural conservation policy in Spain may be considered as part of the efforts carried out by certain intellectual and political leaders in order to institutionalize new spaces of collective identity grounded in landscape and nature (and, more particularly, in some natural landscapes endowed with a strong historic symbolic meaning as regards to the “birth of the nation”. According to the research conclusions, the ideological controversies raised around the first Spanish Natural Parks can be understood as a reflection of the plurality of competing national conceptions existing in Spain, as well as of the difficulties in reaching a consensus on the country’s national symbols.

  11. Case report: massive postpartum transfusion of Jr(a+) red cells in the presence of anti-Jra.

    Jr(a) is a high-prevalence antigen. The rare Jr(a-) individuals can form anti-Jr(a) after exposure to the Jr(a) antigen through transfusion or pregnancy. The clinical significance of anti-Jr(a) is not well established. This study reports a case of a 31-year-old woman with a previously identified anti-Jr(a) who required massive transfusion of RBCs after developing life-threatening postpartum disseminated intravascular coagulopathy. Despite the emergent transfusion of 15 units of Jr(a) untested RBCs, she did not develop laboratory or clinical evidence of acute hemolysis. The patient's anti-Jr(a) had a pretransfusion titer of 4 and a monocyte monolayer assay (MMA) reactivity of 68.5% (reactivity > 5% is considered capable of shortening the survival of incompatible RBCs). The titer increased fourfold to 64 and the MMA reactivity was 72.5% on Day 10 posttransfusion. Review of laboratory data showed evidence of a mild delayed hemolytic transfusion reaction by Day 10 posttransfusion. Despite rare reports of hemolytic transfusion reactions due to anti-Jr(a) in the literature, most cases, including this one, report that this antibody is clinically insignificant or causes only mild delayed hemolysis. Clinicians should be advised to balance the risks of withholding transfusion with the small chance of significant hemolysis after transfusion of Jr(a+) RBCs in the presence of anti-Jr(a).

  12. Magnetoplasmadynamcis - Portrait of Macon C. 'Mike' Ellis, Jr

    Science.gov (United States)

    1962-01-01

    Portrait of Macon C. 'Mike' Ellis, Jr. James Hansen described Mike Ellis as 'the first and only person to be in charge of Langley's Magnetoplasmadynamcis (MPD) Branch.' He was 'an NACA veteran who was 42 years old when the branch was organized. Ellis had come to work at Langley in 1939, and over the course of his career at the laboratory, he had been involved in pioneering work on the aerodynamics of jet engines, ramjets, and supersonic inlets and nozzles. Fittingly, Ellis had worked for Eastman Jacobs and with Arthur Kantrowitz in the early 1940s, and he had heard firsthand accounts of his former colleagues' attempts to design a fusion reactor in the spring of 1938. By the late 1950s, Ellis was one of Langley's most outspoken believers in MPD's promise of technological benefits. Ellis encouraged Floyd Thompson's enthusiasm for MPD and persuaded Langley's senior staff of mostly engineers that MPD was a field of research vital to the future of NASA. When the time came to pick someone to head the new branch, Ellis was unquestionably the person for the job. 'Ellis was no extraordinary 'scientific brain.' As an aeronautical engineer, his talents were quite respectable, but he possessed no special competency in the physics of fluids beyond his experience in aerodynamics or gas dynamics. He was always the first to admit that the complexities of plasma physics and MPD were such that 'there was no way' that he personally could conduct basic MPD research. That challenge he would leave to minds more suited for it. But Ellis could bring the MPD researchers together as a unit, serve as their strong external advocate, shield them from front-office pressures, and make sure that they received the support they needed to carry out their work. 'I just tried to keep my head above water,' Ellis explains, 'and keep these *mad scientists' from going off on too many tangents, or going mad myself.' Published in James R.

    Full Text Available The Battle of the Dardanelles (Çanakkale, also known as the Gallipoli Campaign, played a crucial role in the construction and endorsement of national identity, irrespective of the immediate consequences such as the prolongation of the war or the resignation of Winston Churchill upon failure. The Battle of the Dardanelles is commemorated every year in Turkey, Australia and New Zealand, as a day of remembrance. The battlefields at Dardanelles were reinstated as the Gallipoli Peninsula Historical National Park in 1973. The park covers numerous cemeteries of soldiers from both sides, memorials, museums and the battlefields in an area of 33,000 hectares. The park provides a vivid setting and depiction of the war experience, and stands out as the most important battlefield site in Turkey.The aim of this paper is to analyze battlefield tourism in Çanakkale in terms of its components and its impact on domestic and international tourism in Turkey. Battlefield tourism in Çanakkale encompasses not only the battlefield itself, but also the Çanakkale Victory Day in Turkey, March 18th, and the Anzac Day in Australia, April 25th. While domestic tourism contributes to the revival of collective memory and to the building of national identity, international tourism provides representations of national heritage as a source of political legitimacy. Unique to this case, battlefield tourism plays a significant role in the construction of a long-distance tourism network between Australia, and Turkey. The annual flow of descendants of ANZAC (Australian and New Zealand Army Corps soldiers is an important source of tourism activity in the area.

    2009-01-01

    Harding Eugene Smith Junior, or Gene, as he was known to family, friends, and colleagues, passed away after an automobile accident in Encinitas, California, on 16 August 2007. He was 60 years old. Gene had recently retired from UCSD after thirty years of service. A memorial service was held at Quail Botanical Gardens in Encinitas, California, on 23 August 2007. A web page is dedicated to his memory at http://harding.smith.muchloved.com, where contributions of memories are invited. Gene was born in San Jose, California in 1947, to Harding Eugene Smith Senior, and Bernice Smith (nee Smith). Harding Smith Senior was an air-force navigator; therefore Gene spent his childhood moving from one air-force base to another. Although an only child, Gene was very close to his cousin Meg, whom he lived nearby to in Gilroy for a time, and the two were like brother and sister. The elder Harding Smith was lost in action over Cambodia in the mid-sixties. Gene was a dedicated student, a boy scout, and a Presidential Scholar. He majored in Physics at Caltech, where he also took a lively interest in the football team and the Glee Club, and was elected a House Officer. To his close friends, he was known at Caltech as Smitty, and the closest of them was Rob Drew, who gave a glimpse into that period of Gene's life at the memorial: "Gene arrived early at campus his first year, in response to an invitation to join the football team. Gene's size and features reminded the head coach of a long-forgotten player named 'Johnson.' After a few days of confusion, Gene simply replaced the name on his helmet. 'Johnson!' coach would yell, 'get in there!' If Johnson was going to get to play, Gene was going to be the best Johnson available!" Gene spent the summer of 1966 working at Kitt Peak, where his lifetime love of observing with ground-based telescopes began, though he learned some things the hard way, such as the fact that trying to squeeze 40,000 numbers onto a computer that stored only 32

  18. Histoire, mémoire et identité nationale History, memory and national identity. A German triptych confronted by present-day social evolutions

    2009-06-01

    Full Text Available La responsabilité morale et politique à l’égard du passé est toujours sous-jacente dans la culture politique allemande. Toute tentative destinée à penser l’identité nationale, à mettre à jour ses principales caractéristiques, se trouve confrontée à la prégnance d’une mémoire collective particulièrement lourde de sens et de conséquences. De récentes polémiques sur l’attitude à adopter face à l’histoire et à l’idée nationale montrent combien cet héritage est structurant dans la réflexion sur la problématique identitaire. Si l’histoire, la mémoire et l’identité semblent indissociables dans ce contexte spécifique, des aspirations à une certaine « normalité » se manifestent quant à la manière de vivre ce passé et de s’exprimer au présent. La chute du Mur de Berlin et la réunification ont replacé le thème de l’identité nationale au centre des débats, réactivant ainsi une forme de dilemme entre un sentiment de culpabilité devant l’histoire et le désir d’un rapport « normalisé » à la nation allemande. Les transformations dont l’Allemagne est le théâtre depuis la dernière décennie rendent toutefois nécessaire le maintien d’une vigilante attention. Une situation d’insécurité économique et sociale, associée au temps qui risque d’atténuer la vivacité de souvenirs pourtant lourds, rappellent que la mémoire conditionne aussi la manière dont une nation réunifiée se projette dans l’avenir et y vit son identité.The moral and political responsibility regarding the past always underlies German political culture. Any attempt to conceive national identity, to update its main features, is faced with the vividness of a meaningful, collective memory, fraught with consequences. Recent controversies about the way to deal with history and the national idea show the extent to which this heritage structures the reflection on identity problems. Though history, memory and

    Full Text Available What are the narrative implications of working through aspects of an identity heritage that may have been partially or wholly lost through a family history of migration or diaspora? How do subjects access dislocated parts of their identity, and which strategies do they employ to (re-create them within their stories? To explore such instances of what I term ‘by proxy’ diasporic experiences, I offer a comparative case study of three novels written by authors with family heritage from the Horn of Africa (Ubah Cristina Ali Farah, Dinaw Mengestu and Nadifa Mohamed, who are now active in different nations and languages. Highlighting the narrative strategies used to bridge the gap between past, present and future in the articulation of identity allows us to grasp the trans-national impact of diaspora mobility on memory work and privileges an awareness of the co-existence of different ‘pasts’ within national contexts.This article is published under a CC-BY license https://creativecommons.org/licenses/by/3.0/

More than 60 nations representing 1.7 billion people or three quarters of the world's population were consumed by its horror. Not surprisingly, therefore, World War II stands as a landmark episode in history education throughout the world and its…

    Nation er et gammelt begreb, som kommer af det latinske ord for fødsel, natio. Nationalisme bygger på forestillingen om, at mennesker har én og kun én national identitet og har ret til deres egen nationalstat. Ordet og forestillingen er kun godt 200 år gammel, og i 1900-tallet har ideologien bredt...... sig over hele verden. Nationalisme er blevet global....

    Our memories are not all created equally strong: Some experiences are well remembered while others are remembered poorly, if at all. Research on memory modulation investigates the neurobiological processes and systems that contribute to such differences in the strength of our memories. Extensive evidence from both animal and human research indicates that emotionally significant experiences activate hormonal and brain systems that regulate the consolidation of newly acquired memories. These effects are integrated through noradrenergic activation of the basolateral amygdala which regulates memory consolidation via interactions with many other brain regions involved in consolidating memories of recent experiences. Modulatory systems not only influence neurobiological processes underlying the consolidation of new information, but also affect other mnemonic processes, including memory extinction, memory recall and working memory. In contrast to their enhancing effects on consolidation, adrenal stress hormones impair memory retrieval and working memory. Such effects, as with memory consolidation, require noradrenergic activation of the basolateral amygdala and interactions with other brain regions. PMID:22122145

    2014-01-01

    Inevitably, there are times in a nation’s history when its hopes, fears and confidence in its own destiny appear to hinge on the fate of a single person. One of these pivotal moments occurred on the early morning of May 5, 1961, when a 37-year-old test pilot squeezed himself into the confines of the tiny Mercury spacecraft that he had named Freedom 7. On that historic day, U.S. Navy Commander Alan Shepard carried with him the hopes, prayers, and anxieties of a nation as his Redstone rocket blasted free of the launch pad at Cape Canaveral, hurling him upwards on a 15-minute suborbital flight that also propelled the United States into the bold new frontier of human space exploration. This book tells the enthralling story of that pioeering flight as recalled by many of the participants in the Freedom 7 story, including Shepard himself, with anecdotal details and tales never before revealed in print. Although beaten into space just three weeks earlier by the Soviet cosmonaut Yuri Gagarin, Alan Shepard’s h...

    a decade. His scrupulous integrity and forthright honesty served him, and the Society, well. Despite his scathing intolerance for administrative stupidity, he also managed to complete successfully a term as Chair of the Department of Astronomy. (This author, who currently holds the Chair and shares the intolerance, has yet to fathom the gracious equanimity Norm displayed.) His early interest in brewing beer during graduate school at Cornell (where he co-founded the Old Undershirt Brewing Company) was transformed in later life into an expertise in German wines. The precision that marked his research extended to every aspect of his private life. I had the distinct pleasure of subletting his apartment during my first year on the faculty at Columbia while he was on leave in Europe. We spent most of the year trying to imagine how we could ever restore it to the state of perfect organization in which we found it. Norm is survived by his wife and constant companion of thirty years, psychiatrist Doris Blum Nagel, by his sister Dr. Jean Trousdale, and brother Dr. Richard C. Baker, two nieces, three nephews, and by several generations of undergraduates, graduate students, postdocs, and colleagues who hold fond memories of his patience, kindness, humor, and quiet "joie de vivre".

  13. Aiming at Targets: The Autobiography of Robert C. Seamans, Jr.

    Science.gov (United States)

    Seamans, Robert C., Jr.

    1996-01-01

    Bob Seamans originally was inspired to write this book for his family and friends. That is a large audience. By his own count his immediate family numbers twenty-four, not counting brothers and cousins and their families. His friends are uncounted but surely run to hundreds. As one of them and as a colleague at NASA, I am pleased and honored that he asked me to write this foreword. While written in Bob's unique and informal style, this autobiography has significance for many readers beyond his large circles of family and friends. Leaders and students of large, complex technological endeavors should be able to learn much from reading how Bob faced the daunting technical and management challenges in his career. As the title of this book implies, Bob has always set high goals for himself and then kept his eyes focused on both the necessary details and the broader picture. His ability to shift smoothly among jobs that required seemingly disparate abilities and skills speaks volumes about his insight, dedication, and enthusiasm for achievement. The book spans a truly remarkable life story. Bob first takes us through his growing up, education, and early professional and family life. Next he focuses on the crucial years when he was the general manager of NASA. Then he moves on to his career in the top jobs at the Air Force, the National Academy of Engineering, and the Energy Research and Development Administration. Finally, he touches on his later leadership activities in the academic and business worlds. Aiming at Targets is a series of fascinating topical vignettes covering his professional life. Taken together, like broad brushstrokes in an impressionist painting, they give a better picture of Bob Seamans and his work than a detailed recitation of facts and dates could hope to do. This is a cheerful account of an interesting and successful career. The book is full of good stories, with many memorable characters. Like the proverbial sundial, it counts the sunny hours

O objeto de discussão são os bens imateriais já patrimonializados e considerados de relevância nacional para a construção da memória, da identidade e da formação da sociedade brasileira. Na tentativa de contribuir para a discussão, defendemos que a patrimonialização de bens imateriais não diz respeito somente ao registro e a preservação dos costumes, dos modos de fazer e saber de um grupo ou comunidade, mas significa uma intervenção em todo um conjunto de relações concreta e imediatamente vividas por esses grupos e comunidades. Enquanto saberes locais, costumes, modos de viver e fazer dos grupos, se enraízam e se reconstroem nos espaços a que pertencem, nas relações afetivas, nas experiências vivenciadas e nas memórias dos grupos que as mantém.This text aims to make some reflections on the award of the title of National Intangible Heritage of knowledge, ways of living and making to a few groups located in different regions of Brazil.

    The foods availability is a worldwide problem at present, it looks two paradoxical aspects at first appearance. The malnutrition grade and the great losses by rottenness after the harvest time. An alternative to reduce these losses is the use of modern technologies such as food irradiation, which is a recognized process as like as secure and efficient how a conservation process by the FAO, the WHO and the Codex Alimentarius Commission. At present this process is accepted in 40 countries. Since 1986 the National Institute of Nuclear Research in Mexico offers irradiation services to the dried foods enterprises. This work contains magistral conferences dictated by international experts, reflecting the situation of this technology at the present time, the consumer position about the acceptance of irradiated foods, as well as regulations and standards applied in different continents.

    Lo Re, Vincent; Bellini, Lisa M

    2006-08-01

    Dr William Pepper Jr was a prominent Philadelphia physician whose contributions to medicine in the late 19th century are not widely known. As a young physician he rose in stature rapidly due to his abilities as a diagnostician, teacher, writer and researcher. His primary interest, however, was to improve the education of physicians. He orchestrated the creation of America's first university-controlled teaching hospital, the Hospital of the University of Pennsylvania, enabling substantial improvements in clinical training. Pepper later became Provost of the University of Pennsylvania and ambitiously transformed the curriculum of the medical school, providing greater basic science and clinical training. He also worked to establish several institutes and museums in Philadelphia in order to promote academic pursuits, particularly in medicine. William Pepper Jr was one of the 19th century's foremost medical educators and his accomplishments helped reshape the way medicine was taught throughout the United States.

    Full Text Available This paper discusses the influence of the Tvergaard parameters, qi, which are basic constants of the Gurson-Tvergaard-Needleman (GTN material model, on the numerically simulated load-carrying capacity of tensile elements made of S235JR steel. The elements were considered to be under static tension at low initial stress triaxiality σm/σe = 1/3. Two sets of the Tvergaard parameters qi were analyzed: those typical of structural steels and those dependent on material strength properties. The results showed that the Tvergaard parameters, qi, had influence on the load-carrying capacity of tensile elements at low initial stress triaxiality. They affected the strength curves and the changes in the void volume fractions determined for S235JR steel elements

    2010-12-01

    We present an interactive, web-based map utility that can make new geological and geophysical results accessible to a large number and variety of users. The tool provides a user-friendly interface that allows users to access a variety of maps, satellite images, and geophysical data at a range of spatial scales. The map tool, dubbed 'Jules Verne Voyager, Jr.', allows users to interactively create maps of a variety of study areas around the world. The utility was developed in collaboration with the UNAVCO Consortium for study of global-scale tectonic processes. Users can choose from a variety of base maps (including "Face of the Earth" and "Earth at Night" satellite imagery mosaics, global topography, geoid, sea-floor age, strain rate and seismic hazard maps, and others), add a number of geographic and geophysical overlays (coastlines, political boundaries, rivers and lakes, earthquake and volcano locations, stress axes, etc.), and then superimpose both observed and model velocity vectors representing a compilation of 2933 GPS geodetic measurements from around the world. A remarkable characteristic of the geodetic compilation is that users can select from some 21 plates' frames of reference, allowing a visual representation of both 'absolute' plate motion (in a no-net rotation reference frame) and relative motion along all of the world's plate boundaries. The tool allows users to zoom among at least three map scales. The map tool can be viewed at http://jules.unavco.org/VoyagerJr/Earth. A more detailed version of the map utility, developed in conjunction with the EarthScope initiative, focuses on North America geodynamics, and provides more detailed geophysical and geographic information for the United States, Canada, and Mexico. The ‘EarthScope Voyager’ can be accessed at http://jules.unavco.org/VoyagerJr/EarthScope. Because the system uses pre-constructed gif images and overlays, the system can rapidly create and display maps to a large number of users

  4. Narrative Tools,Truth,and Fast Thinking in National Memory:A Mnemonic Standoff between Russia and the West over Ukraine

    Institute of Scientific and Technical Information of China (English)

    James V Wertsch; Bai Meifei; TranslatorZhou Hong

    2015-01-01

    s line of reasoning goes be-yond Vygotsky’s comes from his claim that using symbolic forms introduces the“curse of mediacy,”meaning that this use comes at a cost—a cost that often goes unrecognized. Taken together, the ideas of Vygotsky and Cassirer suggest a world in which speaking and thinking are fundamentally shaped by the symbolic mediation,or cultural tools provided by historical, institutional,and cultural contexts. It is worth no-ting that in this approach cultural tools do not mechanistically determine human discourse and thinking. Instead, the very notion of a tool implies an active user and suggests an element of variabili-ty and freedom stemming from the unique contexts of performance. Returning to Putin’s stance on the 2014 events in Ukraine,the first point to recognize is that what he said was fundamentally shaped by the narrative tools of his mnemonic community, and as such, it makes sense to include the power of these tools into our analytic effort. One of the most important shared narratives that binds the Russian mnemonic community together concerns repeated invasions by foreign enemies. This national memory has encour-aged Russians to develop habits of emplotment, or“narrative templates”( Wertsch, 2002 ) , that lead them to interpret many events in similar way—namely,as threats. This underlying code has been used repeatedly by the Russian mnemonic commu-nity to make sense of events from the past,and it is also employed when interpreting current events. Tense interpretive standoffs such as the one in 2014 over the Ukraine and Crimea are typically grounded in assumptions about the truth of “what really happened.” These “mnemonic standoffs”(Wertsch,2009)about events in the near or distant past are different from other sorts of disputes. When thinking and speaking about Crimea, Putin was not simply listing a series of facts or observa-tions;he was organizing them in line with narrative tools of his mnemonic community,and this

  15. Memory protection

    Science.gov (United States)

    Denning, Peter J.

    1988-01-01

    Accidental overwriting of files or of memory regions belonging to other programs, browsing of personal files by superusers, Trojan horses, and viruses are examples of breakdowns in workstations and personal computers that would be significantly reduced by memory protection. Memory protection is the capability of an operating system and supporting hardware to delimit segments of memory, to control whether segments can be read from or written into, and to confine accesses of a program to its segments alone. The absence of memory protection in many operating systems today is the result of a bias toward a narrow definition of performance as maximum instruction-execution rate. A broader definition, including the time to get the job done, makes clear that cost of recovery from memory interference errors reduces expected performance. The mechanisms of memory protection are well understood, powerful, efficient, and elegant. They add to performance in the broad sense without reducing instruction execution rate.

    We report the results of Suzaku observations of the young supernova remnant, Vela Jr.\\ (RX J0852.0$-$4622), which is known to emit synchrotron X-rays, as well as TeV gamma-rays. Utilizing 39 Suzaku mapping observation data from Vela Jr., a significant hard X-ray emission is detected with the hard X-ray detector (HXD) from the north-west TeV-emitting region. The X-ray spectrum is well reproduced by a single power-law model with the photon index of 3.15$^{+1.18}_{-1.14}$ in the 12--22 keV band. Compiling this with the soft X-ray spectrum simultaneously observed with the X-ray imaging spectrometer (XIS) onboard Suzaku, we find that the wide-band X-ray spectrum in the 2--22 keV band is reproduced with a single power-law or concave broken power-law model, which are statistically consistent with each other. Whichever the model of a single or broken power-law is appropriate, clearly the spectrum has no rolloff structure. Applying this result to the method introduced in \\citet{yama2014}, we find that one-zone synchro...

    To evaluate current perioperative antithrombotic management in neuroendovascular therapy in Japan, we analyzed perioperative anticoagulant and antiplatelet use in various procedures and examined their relationships with periprocedural adverse events. Patient's data from nationwide surveys administered by the Japanese Registry of Neuroendovascular Therapy (JR-NET) between January 2005 and December 2007 (JR-NET1) and January 2008 and December 2009 (JR-NET2) were retrospectively analyzed. Compared to JR-NET1, the frequency of perioperative antiplatelet therapy and dual or triple therapy were increased for either aneurysm coiling and percutaneous transluminal angioplasty or stenting in JR-NET2. Although ischemic complications were significantly decreased (4.2% vs. 2.1%, p antiplatelet therapy (preoperative: 5.3% vs. 9.2%, p therapy was performed more frequently and intensively in neuroendovascular therapy in Japan. While ischemic complications were decreased, hemorrhagic complications and severe adverse events were increased. These results suggest that intensive antithrombotic therapy has a potential risk of hemorrhagic complications for Japanese patients. PMID:24305029

    After the civil war and the Hurricane-Mitch disaster, cattlemen in Nicaragua were forced to transport their cattle from lowland areas to higher, dryer areas of the country. These areas are natural ecological niches for the cattle grub Dermatobia hominis (L. Jr.) (Diptera: Cuterebridae). To determine the importance of this infestation, the Agricultural and Livestock-Forestry Ministry selected a central area of Nicaragua to run a pioneer survey program to acquire information about hosts involved, number of cases, treatments applied and general knowledge of 42 farmers about the life cycle of the parasite. The subjects were either farm owners or farm managers. Ninety-five percentage of the farms indicated cases of D. hominis infestation in their animals, with cattle being the most affected host (100% of the affected farms). There was poor understanding of the D. hominis life cycle, vectors and control methods. A misuse of insecticides for the treatment of larval infestation by D. hominis was indicated.

    The 2010 Julius H. Comroe, Jr., Lecture of the American Physiological Society focuses on evolving ideas in chemoreception for CO₂/pH in terms of what is "sensed," where it is sensed, and how the sensed information is used physiologically. Chemoreception is viewed as involving neurons (and glia) at many sites within the hindbrain, including, but not limited to, the retrotrapezoid nucleus, the medullary raphe, the locus ceruleus, the nucleus tractus solitarius, the lateral hypothalamus (orexin neurons), and the caudal ventrolateral medulla. Central chemoreception also has an important nonadditive interaction with afferent information arising at the carotid body. While ventilation has been viewed as the primary output variable, it appears that airway resistance, arousal, and blood pressure can also be significantly affected. Emphasis is placed on the importance of data derived from studies performed in the absence of anesthesia.

  12. Memory conformity affects inaccurate memories more than accurate memories.

    Wright, Daniel B; Villalba, Daniella K

    2012-01-01

    After controlling for initial confidence, inaccurate memories were shown to be more easily distorted than accurate memories. In two experiments groups of participants viewed 50 stimuli and were then presented with these stimuli plus 50 fillers. During this test phase participants reported their confidence that each stimulus was originally shown. This was followed by computer-generated responses from a bogus participant. After being exposed to this response participants again rated the confidence of their memory. The computer-generated responses systematically distorted participants' responses. Memory distortion depended on initial memory confidence, with uncertain memories being more malleable than confident memories. This effect was moderated by whether the participant's memory was initially accurate or inaccurate. Inaccurate memories were more malleable than accurate memories. The data were consistent with a model describing two types of memory (i.e., recollective and non-recollective memories), which differ in how susceptible these memories are to memory distortion.

    The crystallization and preliminary X-ray crystallographic analysis of a plant PPO exhibiting monophenolase activity from J. regia (jrPPO1) in its active form (Asp{sup 101}–Arg{sup 445}) are reported. Tyrosinase is a type 3 copper enzyme that catalyzes the ortho-hydroxylation of monophenols to diphenols as well as their subsequent oxidation to quinones, which are precursors for the biosynthesis of melanins. The first plant tyrosinase from walnut leaves (Juglans regia) was purified to homogeneity and crystallized. During the purification, two forms of the enzyme differing only in their C-termini [jrPPO1(Asp{sup 101}–Pro{sup 444}) and jrPPO1(Asp{sup 101}–Arg{sup 445})] were obtained. The most abundant form jrPPO1(Asp{sup 101}–Arg{sup 445}), as described in Zekiri et al. [Phytochemistry (2014 ▶), 101, 5–15], was crystallized, resulting in crystals that belonged to space group C121, with unit-cell parameters a = 115.56, b = 91.90, c = 86.87 Å, α = 90, β = 130.186, γ = 90°, and diffracted to 2.39 Å resolution. Crystals were only obtained from solutions containing at least 30% polyethylene glycol 5000 monomethyl ether in a close-to-neutral pH range.

    Although recently published case reports suggest the significance of Jr(a) alloimmunization in the obstetric setting, the involved mechanism still remains unclear. Here we report a case of severe fetal and neonatal anemia associated with anti-Jr(a) alloimmunization, which was successfully managed using Doppler assessment of peak systolic velocity of the fetal middle cerebral artery (MCA-PSV). A Japanese woman with anti-Jr(a) (titer 1024) was referred to our department at 20 weeks' gestation. As fetal MCA-PSV exceeded 1.5 multiple of median, labor was induced and a female neonate of 1998 g was delivered vaginally at 33 weeks and 5 days of gestation. The infant's hematocrit and hemoglobin levels were 25.4% and 82 g/L, respectively, but her total bilirubin level (15 µmol/L; 0.9 mg/dL) and reticulocyte counts (4.5%) were low. During the course, the infant showed no apparent signs of hemolysis. Jr(a) alloimmunization should be recognized as a possible cause of fetal anemia with no direct hemolytic process. © 2011 The Authors.

  5. J-R Curve Determination for Disk-shaped Compact Specimens Based on the Normalization Method and Direct Current Potential Drop Technique

    Energy Technology Data Exchange (ETDEWEB)

    Chen, Xiang [ORNL; Nanstad, Randy K [ORNL; Sokolov, Mikhail A [ORNL

    2014-01-01

    Material ductile fracture toughness can be described by J-integral versus crack extension relationship (J-R curve). As a conventional J-R curve measurement method, unloading compliance (UC) becomes impractical in elevated temperature testing due to relaxation of the material and a friction induced back-up shape of the J-R curve. In addition, the UC method may underpredict the crack extension for standard disk-shaped compact (DC(T)) specimens. In order to address these issues, the normalization method and direct current potential drop (DCPD) technique were applied for determining J-R curves at 24 C and 500 C for 0.18T DC(T) specimens made from type 316L stainless steel. For comparison purchase, the UC method was also applied in 24 C tests. The normalization method was able to yield valid J-R curves in all tests. The J-R curves from the DCPD technique need adjustment to account for the potential drop induced by plastic deformation, crack blunting, etc. and after applying a newly-developed DCPD adjustment procedure, the post-adjusted DCPD J-R curves essentially matched J-R curves from the normalization method. In contrast, the UC method underpredicted the crack extension in all tests resulting in substantial deviation in the derived J-R curves manifested by high Jq values than the normalization or DCPD method. Only for tests where the UC method underpredicted the crack extension by a very small value, J-R curves determined by the UC method were similar to those determined by the normalization or DCPD method.

  7. Plutino 15810 (1994 JR1), an accidental quasi-satellite of Pluto

    CERN Document Server

    Marcos, C de la Fuente

    2012-01-01

    In the solar system, quasi-satellites move in a 1:1 mean motion resonance going around their host body like a retrograde satellite but their mutual separation is well beyond the Hill radius and the trajectory is not closed as they orbit the Sun not the host body. So far, minor bodies temporarily trapped in the quasi-satellite dynamical state have been identified around Venus, Earth, the dwarf planet (1) Ceres, the large asteroid (4) Vesta, Jupiter, Saturn and Neptune. Using computer simulations, Tiscareno and Malhotra have predicted the existence of a small but significant population of minor bodies moving in a 1:1 mean motion resonance with Pluto. Here we show using N-body calculations that the Plutino 15810 (1994 JR1) is currently an accidental quasi-satellite of Pluto and it will remain as such for nearly 350,000 yr. By accidental we mean that the quasi-satellite phase is triggered (or terminated) not by a direct gravitational influence in the form of a discrete close encounter but as a result of a resonan...

  8. Memory consolidation.

    Science.gov (United States)

    Squire, Larry R; Genzel, Lisa; Wixted, John T; Morris, Richard G

    2015-08-03

    Conscious memory for a new experience is initially dependent on information stored in both the hippocampus and neocortex. Systems consolidation is the process by which the hippocampus guides the reorganization of the information stored in the neocortex such that it eventually becomes independent of the hippocampus. Early evidence for systems consolidation was provided by studies of retrograde amnesia, which found that damage to the hippocampus-impaired memories formed in the recent past, but typically spared memories formed in the more remote past. Systems consolidation has been found to occur for both episodic and semantic memories and for both spatial and nonspatial memories, although empirical inconsistencies and theoretical disagreements remain about these issues. Recent work has begun to characterize the neural mechanisms that underlie the dialogue between the hippocampus and neocortex (e.g., "neural replay," which occurs during sharp wave ripple activity). New work has also identified variables, such as the amount of preexisting knowledge, that affect the rate of consolidation. The increasing use of molecular genetic tools (e.g., optogenetics) can be expected to further improve understanding of the neural mechanisms underlying consolidation.

  9. Is external memory memory? Biological memory and extended mind.

    Science.gov (United States)

    Michaelian, Kourken

    2012-09-01

    Clark and Chalmers (1998) claim that an external resource satisfying the following criteria counts as a memory: (1) the agent has constant access to the resource; (2) the information in the resource is directly available; (3) retrieved information is automatically endorsed; (4) information is stored as a consequence of past endorsement. Research on forgetting and metamemory shows that most of these criteria are not satisfied by biological memory, so they are inadequate. More psychologically realistic criteria generate a similar classification of standard putative external memories, but the criteria still do not capture the function of memory. An adequate account of memory function, compatible with its evolution and its roles in prospection and imagination, suggests that external memory performs a function not performed by biological memory systems. External memory is thus not memory. This has implications for: extended mind theorizing, ecological validity of memory research, the causal theory of memory.

    The 3:2 resonant KBO (15810) 1994 JR1 was observed by NASA's New Horizons spacecraft on November 2, 2015 from a distance of 1.85 AU, and again on April 7, 2016 from a distance of 0.71 AU. Acquired using the LOng Range Reconnaissance Imager (LORRI), these were the first close observations of any KBO other than Pluto, and the first ever of a small KBO. Combining ground-based and HST observations at small phase angles and the LORRI observations at higher phase angles, we produced the first disk-integrated solar phase curve of a typical KBO from alpha=0.6-58 degrees. Observations at these geometries, attainable only from a spacecraft in the outer Solar System, constrain surface properties such as macroscopic roughness and the single particle phase function. 1994 JR1 has a rough surface with a 37+/-5 degree mean topographic slope angle and has a relatively rapid rotation period of 5.47+/-0.33 hours. 1994 JR1 is currently 2.7 AU from Pluto; our astrometric points enable high-precision orbit determination and integr...

    Emil Godlewski, Jr. (1875-1944) lived and worked in Krakow. He graduated from the Faculty of Medicine of the Jagiellonian University with the title of Doctor of Medical Science. He worked at the Faculty of Medicine, first in the Institute of Descriptive Anatomy and later as Professor of Biology and Embryology in the Department of Biology and Embryology, which he founded and led for many years. After early research on the development and histogenesis of muscles, professor Godlewski's scientific interests focused on regeneration and mechanisms regulating the process of fertilization, as well as early embryo development, blastulation and gastrulation. He was also interested in the origin of the primary differentiating cells in regenerates. He postulated the importance of epithelial tissue in this process and was the first to point out the change in the function, organization and role of the cells under the influence of external stimuli. Investigating fertilization and early development, he focused on the cooperation between the nucleus and the cytoplasm in the regulation of the early stages of development. Godlewski was also the author of the theory of migration of the inherited substances from the nucleus to the cytoplasm and, after their processing, from the cytoplasm to the nucleus. His works were never fragmentary, but always synthetical attempts at explaining important issues relating to the mechanisms of development. In 1936 Professor Godlewski was awarded the title of Member of the Pontifica Accademia delle Scienze. Apart from doing research and teaching, Emil Godlewski devoted a lot of time to social issues, especially those connected to medicine. When Poland regained independence after World War I, he actively participated in the reopening of the Jagiellonian University.

    Background Episodic memory includes information about item memory and source memory.Many researches support the hypothesis that these two memory systems are implemented by different brain structures.The aim of this study was to investigate the characteristics of item memory and source memory processing in patients with Parkinson's disease (PD),and to further verify the hypothesis of dual-process model of source and item memory.Methods We established a neuropsychological battery to measure the performance of item memory and source memory.Totally 35 PD individuals and 35 matched healthy controls (HC) were administrated with the battery.Item memory task consists of the learning and recognition of high-frequency national Chinese characters; source memory task consists of the learning and recognition of three modes (character,picture,and image) of objects.Results Compared with the controls,the idiopathic PD patients have been impaired source memory (PD vs.HC:0.65±0.06 vs.0.72±0.09,P=0.001),but not impaired in item memory (PD vs.HC:0.65±0.07 vs.0.67±0.08,P=0.240).Conclusions The present experiment provides evidence for dissociation between item and source memory in PD patients,thereby strengthening the claim that the item or source memory rely on different brain structures.PD patients show poor source memory,in which dopamine plays a critical role.

  7. HST observations of the nebula around the central compact object in the Vela Jr. supernova remnant

    Science.gov (United States)

    Mignani, R. P.; de Luca, A.; Pellizzoni, A.

    2009-12-01

    Context: A handful of young (a few thousand years) supernova remnants (SNRs) host point-like X-ray sources, dubbed central compact objects (CCOs), which are thought to be radio-silent isolated neutron stars formed by the supernova explosion. So far, no CCO has been firmly detected at other wavelengths. However, ground-based observation in the Hα band detected a nebula around CXO J085201.4-461753, the CCO in the Vela Jr. SNR. The nebula has also been detected in deep R-band observations performed with the Very Large Telescope (VLT). Interestingly, both its extension and its flux in the R band are consistent with those measured in Hα, suggesting that the nebula spectrum is dominated by line emission, possibly produced by a velocity-driven bow-shock in the interstellar medium (ISM) or by its photo-ionisation from the neutron star. Aims: The aim of this work is to resolve the morphology of the Hα nebula around the CCO to verify the proposed interpretations. Methods: We performed high-resolution imaging observations of the nebula with the Wide Field Planetary Camera 2 (WFPC2) of the Hubble Space Telescope (HST) through the 656N filter, almost exactly centred on the rest wavelength of the Hα line. Results: Surprisingly enough, we did not detect the nebula in our WFPC2 image down to a 3 σ flux limit of ~3 × 10-15 erg cm-2 s-1. This limit is a factor of 10 fainter than the nebula flux measured in the discovery ground-based observations which were, however, performed with redder and broader Hα filters. Conclusions: The non-detection of the nebula in the narrower and bluer WFPC2 656N filter suggests that the peak of the emission might actually be at longer wavelengths. One possibility, compatible with the bow-shock scenario only, is that the Hα line is red-shifted by ~10-60 Å due to the neutron star motion with a radial velocity 450 ⪉ Vr ⪉ 2700 km s-1. The other possibility is that the nebula is a knot of [NII] emission (λ = 6583.6 Å) unrelated to CXO J085201

    Memory can be divided into several types, although all of them involve three successive processes: encoding, storage, and retrieval. In terms of the duration of retention, neurologists classify memory into immediate, recent, and remote memories, whereas psychologists classify memory into short-term and long-term memories. In terms of the content, episodic, semantic, and procedural memories are considered to be different types of memory. Furthermore, researchers on memory have proposed relatively new concepts of memory, i.e., working memory and prospective memory. This article first provides explanations for these several types of memory. Next, neuropsychological characteristics of amnesic syndrome are briefly outlined. Finally, how several different types of memory are affected (or preserved) in patients with amnesic syndrome is described.

    Cyclic J-R behaviour of a reactor pressure vessel steel using different methods available in literature has been examined to identify the best suitable method for cyclic fracture problems. Crack opening point was determined by moving average method. The η factor was experimentally determined for cyclic loading conditions and found to be similar to that of ASTM value. Analyses showed that adopting a procedure analogous to the ASTM standard for monotonic fracture is reasonable for cyclic fracture problems, and makes the comparison to monotonic fracture results straightforward.

    The advent of multicore processors has renewed interest in the idea of incorporating transactions into the programming model used to write parallel programs.This approach, known as transactional memory, offers an alternative, and hopefully better, way to coordinate concurrent threads. The ACI(atomicity, consistency, isolation) properties of transactions provide a foundation to ensure that concurrent reads and writes of shared data do not produce inconsistent or incorrect results. At a higher level, a computation wrapped in a transaction executes atomically - either it completes successfullyand

    Full Text Available The paper analyzes the calendrical struggles over mastering symbolic time in Romanian modern history by scrutinizing the logic of constructing, deconstructing, and reconstructing a temporal order made up of political holidays celebrated within a festive calendar. It looks, first, at how the constitutional monarchic political order established in 1866 with the enthronement of Carol I as Ruling Prince of Romania developed a royal festive calendar pillared on the National Day of the 10th of May. By analyzing the making of the royal temporal order organized within a national festive calendar, three techniques of calendrical construction are identified and detailed: a calendrical shifting, b calendrical concentration, and c celebrative sequencing employed for framing temporal coincidence and staging festive density. After presenting how the festive calendar was articulated using these techniques for the purpose of legitimating the monarchic order, the paper goes on to address how the Socialist republican regime established in the aftermath of the Second World War tried and succeeded not only in abolishing the dynastic monarchy through a political revolution but also in overthrowing the entire royal calendar of political celebrations through a symbolic revolution in the politics of festive time. The paper identifies four techniques of calendrical deconstruction used by the Socialist regime to destructure the royal festive calendar and supplant it with a republican one: a calendrical decentering, b calendrical concentration, c symbolic downgrading, and d shifting the celebrative weight. In exploring these techniques of calendrical construction and deconstruction, the study underscores the power struggles intrinsic to organizing festive time. The paper ends with highlighting the crucial importance played out by commemorations, ceremonials, and festivities by which social time is politically structured and ritually punctuated in legitimizing political

    As supercomputers continue to get faster and more powerful in the future, they will also have more nodes. If nothing is done, then the amount of memory in supercomputer clusters will soon grow large enough that memory failures will be unmanageable to deal with by manually replacing memory DIMMs. "Improving Memory Error Handling Using Linux" is a process oriented method to solve this problem by using the Linux kernel to disable (offline) faulty memory pages containing bad addresses, preventing them from being used again by a process. The process of offlining memory pages simplifies error handling and results in reducing both hardware and manpower costs required to run Los Alamos National Laboratory (LANL) clusters. This process will be necessary for the future of supercomputing to allow the development of exascale computers. It will not be feasible without memory error handling to manually replace the number of DIMMs that will fail daily on a machine consisting of 32-128 petabytes of memory. Testing reveals the process of offlining memory pages works and is relatively simple to use. As more and more testing is conducted, the entire process will be automated within the high-performance computing (HPC) monitoring software, Zenoss, at LANL.

    Full Text Available This article is devoted to childhood memories of the war as recorded in the 2000s. It considers peculiarities of children’s memory, and mechanisms for actualization of memories of various events of wartime. It is noted that the memory of the war still remains one of the few sources for the national pride of the modern Russian society. At the same time, rehabilitation of multiple private memories results in erosion of the official version and calls persistently for their reconciliation. Meanwhile memory is no longer viewed by the researcher as a “passive storage of recorded information” but is connected with figural reconstruction of images from the past. Despite a number of peculiarities in children’s memories, they are going to become the touchstone to clear up the peculiarities of forming the memory of the Great Patriotic War, its dynamics and present-day condition.

    Diagnosing pleural effusion is challenging, especially in patients with malignant or benign fibrothorax, which is difficult to sample using standard flexible forceps (SFF) via flex-rigid pleuroscopy. An adequate sample is crucial for the differential diagnosis of malignant fibrothorax (malignant pleural mesothelioma, metastatic lung carcinoma, etc.) from benign fibrothorax (benign asbestos pleural disease, tuberculous pleuritis, etc.). Novel biopsy techniques are required in flex-rigid pleuroscopy to improve the sample size and quality. The SB knife Jr, which is a scissor forceps that uses a mono-pole high frequency, was developed to allow convenient and accurate resection of larger lesions during endoscopic dissection (ESD). Herein, we report two patients with fibrothorax who underwent a pleural biopsy using an SB knife Jr to investigate the potential use of this tool in flex-rigid pleuroscopy when pleural lesions are difficult to biopsy via SFF. The biopsies were successful, with sufficient size and quality for definitive diagnosis. We also successfully performed adhesiolysis with the SB knife Jr in one case, and adequate biopsies were conducted. No complications were observed. Electrosurgical biopsy with the SB knife Jr during flex-rigid pleuroscopy allowed us to obtain adequate samples for the diagnosis of malignant versus benign fibrothorax, which is usually not possible with SFF. The SB knife Jr also demonstrated a potential use for pleuropulmonary adhesions.

    Numerous efforts have been conducted in searching for effective agents against cancer, in particular from herbal medicines. Justicia procumbens is a traditional herbal remedy which was produced in the south-western and southern provinces of China and Taiwan province used to treat fever, pain, and cancer. Here, we identified a new compound 6'-hydroxy justicidin A (JR6) from Justicia procumbens, which showed obvious anti-cancer effects. The cytotoxicity activity was assayed using MTT and SRB. Intracellular ROS visualization and quantification were acquired by using a laser scanning confocal microscopy. Apoptosis was measured using a propidium iodide (PI) apoptosis detection kit by flow cytometry. Activation of caspases (caspase-3, caspase-8, and caspase-9) was evaluated respectively using GloMax luminescence detector and Caspase-Glo 3,8,9 assay kits. Loss of mitochondrial membrane potential was observed by microscopy using JC-1 dye. Quantitative real-time PCR analysis was employed to detect the expression of protein associated with cell death. JR6 remarkably inhibited growth in human bladder cancer EJ cells by decreasing cell proliferation, reduced the SOD activity, increased the content of reactive oxygen species (ROS), and induced apoptosis. Activation of caspase-8, caspase-9, and the subsequent activation of caspase-3 indicated that JR6 may be inducing intrinsic and extrinsic apoptosis pathways. Caspase-3, caspase-8, and caspase-9 inhibition rendered this extract ineffective, thus JR6-induced apoptosis is caspase-dependent. JR6 also disrupted the mitochondrial membrane potential (Δψm) and unregulated the Bax and p53 expressions in EJ cells. These observations suggest that JR6 induce apoptosis through caspase-dependent pathway in human bladder cancer EJ cells, emphasizing the importance of this traditional medicine and thus presents a potential novel alternative to bladder cancer therapy.

    2015-03-01

    Collective oscillation of spins in magnetic lattice known as spin waves (magnons) possess relatively long coherence length at room temperature, which makes it possible to build sub-micrometer scale holographic devices similar to the devices developed in optics. In this work, we present a prototype 2-bit magnonic holographic memory. The memory consists of the double-cross waveguide structure made of Y3Fe2(FeO4)3 with magnets placed on the top of waveguide junctions. Information is encoded in the orientation of the magnets, while the read-out is accomplished by the spin waves generated by the micro-antennas placed on the edges of the waveguides. The interference pattern produced by multiple spin waves makes it possible to build a unique holographic image of the magnetic structure and recognize the state of the each magnet. The development of magnonic holographic devices opens a new horizon for building scalable holographic devices compatible with conventional electronic devices. This work was supported in part by the FAME Center, one of six centers of STARnet, a Semiconductor Research Corporation program sponsored by MARCO and DARPA and by the National Science Foundation under the NEB2020 Grant ECCS-1124714.

The objective is to replace existing memories (DRAM, SRAM, EEPROM, Flash, etc.) with a universal memory model likely to reach better performances than the current types of memory: extremely high commutation speeds, high implantation densities and retention time of information of about ten years.

  11. CULTURE OF MEMORY AND SOME MODELS OF MEMORY ABOUT THE ARMENIAN GENOCIDE IN CONTEMPORARY ARMENIAN SOCIETY

    Directory of Open Access Journals (Sweden)

    A. V. ATANESYAN

    2016-01-01

    Full Text Available The article reveals modern approaches to the culture of collective memory addressing the cornerstone historical events which influenced the further course of history and national identity construction. The question of how to construct the collective memory about wars, genocide, mass suffering is one of the most important issues in the modern historiography, sociology and social psychology, political science, and related disciplines. The "politics of memory", which also includes such categories as "ethics and culture of memory," essentially determines the ability of the nation to overcome its collective trauma, to find ways for selfdevelopment and development of the country, and the further role and place of the nation in the system of international relations. This article discusses the current research studies on the culture of memory applied to the Holocaust, the present approaches to the definition and implementation of strategies of politics of memory, and memory models developed by modern scholars on the Holocaust remembrance. The Armenian Genocide of 1915 in the Ottoman Empire serves as object of the analysis. The subject of the analysis includes the approaches to the memory about the Armenian Genocide in the modern Armenian society, which is discussed here as the complex culture of memory on the Armenian Genocide, which is partly resulted of the official politics of memory implemented by Armenian authorities, as well as practiced by the Armenian Diaspora, and is partly a consequence of manifestations of national identity and collective memory at the level of society, social groups and individuals. The article is an attempt to identify the memory models in scientific research studies, in particular with regard to the memory of the Holocaust, and analyze their application / applicability to the culture and social practices of the memory of the Armenian Genocide.

  13. Verbal memory and menopause.

    Maki, Pauline M

    2015-11-01

    Midlife women frequently report memory problems during the menopausal transition. Recent studies validate those complaints by showing significant correlations between memory complaints and performance on validated memory tasks. Longitudinal studies demonstrate modest declines in verbal memory during the menopausal transition and a likely rebound during the postmenopausal stage. Clinical studies that examine changes in memory following hormonal withdrawal and add-back hormone therapy (HT) demonstrate that estradiol plays a critical role in memory. Although memory changes are frequently attributed to menopausal symptoms, studies show that the memory problems occur during the transition even after controlling for menopausal symptoms. It is well established that self-reported vasomotor symptoms (VMS) are unrelated to objective memory performance. However, emerging evidence suggests that objectively measured VMS significantly correlate with memory performance, brain activity during rest, and white matter hyperintensities. This evidence raises important questions about whether VMS and VMS treatments might affect memory during the menopausal transition. Unfortunately, there are no clinical trials to inform our understanding of how HT affects both memory and objectively measured VMS in women in whom HT is indicated for treatment of moderate to severe VMS. In clinical practice, it is helpful to normalize memory complaints, to note that evidence suggests that memory problems are temporary, and to counsel women with significant VMS that memory might improve with treatment.

  16. Creation and covenant in a via media position: The example of J.J.P. Valeton Jr

    Directory of Open Access Journals (Sweden)

    Bob Becking

    2013-06-01

    Full Text Available The year 2012 marked the centenary of the death of the Utrecht Old Testament scholar J.J.P. Valeton Jr (1848–1912. He was a representative of the ‘via media’ approach of Dutch theology, which aimed at joining critical scholarship and piety, by avoiding the pitfalls of modernism as well as orthodoxy. Valeton accepted the critical analysis of Graf, Kuenen, and Wellhausen, but meanwhile remained a pious person. This article will discuss Valeton’s contributions to critical scholarship of Genesis 1–3 as well as his profound ideas on ‘covenant’ as an expression of ‘friendship’. Loader’s distinction between ‘knowledge open to faith’ and ‘knowledge open for scientific approach’ is very helpful in understanding the works and ideas of Valeton.

  19. The Microcosm within: An interview with William B. Miller, Jr., on the Extended Hologenome theory of evolution.

    Science.gov (United States)

    Hunt, Tam

    2015-01-01

    There is a singular unifying reality underlying every biologic interaction on our planet. In immunology, that which does not kill you makes you different. -William B. Miller, Jr. We are experiencing a revolution in our understanding of inner space on a par with our exponentially increasing understanding of outer space. In biology, we are learning that the genetic and epigenetic complexity within organisms is far deeper than suspected. This is a key theme in William B. Miller Jr.'s book, The Microcosm Within: Evolution and Extinction in the Hologenome. We are learning also that a focus on the human genome alone is misleading when it comes to who we really are as biological entities, and in terms of how we and other creatures have evolved. Rather than being defined by the human genome alone, we are instead defined by the "hologenome," the sum of the human genome and the far larger genetic endowment of the microbiome and symbiotic communities that reside within and around us. Miller is a medical doctor previously in private practice in Pennsylvania and Phoenix, Arizona. This book is his first foray into evolutionary theory. His book could have been titled "The Origin of Variation" because this is his primary focus. He accepts that natural selection plays a role in evolution, but he demotes this mechanism to a less important role than the Modern Synthesis suggests. His main gripe, however, concerns random variation. He argues that random variation is unable to explain the origin and evolution of biological forms that we see in the world around us and in the historical record. Miller suggests that, rather than random variation as the engine of novelty, there is a creative impulse at the heart of cellular life, and even at the level of the genetic aggregate, that generates novelty on a regular basis. I probe this assertion in the interview below. He also highlights the strong role of "exogenous genetic assault" in variation and in his immunological model of evolution.

  20. From Collective Memory to Transcultural Remembrance

    Directory of Open Access Journals (Sweden)

    Matthew Graves

    2010-05-01

    Full Text Available Over the last thirty or so years, historians and social scientists have undertaken a wide ranging exploration of the processes involved in forgetting and remembering, with a particular focus on the level of the nation-state. Their interest corresponds to the period that Pierre Nora, the French historian responsible for the ground-breaking Les Lieux de memoire in the 1980s, terms the ‘era of commemoration,’ drawing attention to what he describes as the ‘tidal wave of memorial concerns that has broken over the world.’ Across the world, nation-states have paid renewed attention to the ceremonial and observance of national days, and have undertaken campaigns of education, information, even legislation, to enshrine the parameters of national remembering and therefore identity, while organisations and institutions of civil society and special interest groups have sought to draw the attention of their fellow citizens to their particular experiences, and perhaps gain national recognition for what they believe to have been long overlooked or forgotten. This article traces the over-lapping evolution of the practices of commemoration, the politics of memory and the academic field of ‘Memory Studies.’ It seeks in particular to identify the theoretical and methodological advances that have moved the focus of the study of memory from the static and homogenising category of ‘collective memory’ to practices of remembering, and from national to transcultural perspectives.

    Burgess, Colin

    2015-01-01

    In this spellbinding account of an historic but troubled orbital mission, noted space historian Colin Burgess takes us back to an electrifying time in American history, when intrepid pioneers were launched atop notoriously unreliable rockets at the very dawn of human space exploration.   A nation proudly and collectively came to a standstill on the day this mission flew; a day that will be forever enshrined in American spaceflight history. On the morning of February 20, 1962, following months of frustrating delays, a Marine Corps war hero and test pilot named John Glenn finally blazed a path into orbit aboard a compact capsule named Friendship 7.   The book’s tension-filled narrative faithfully unfolds through contemporary reports and the personal recollections of astronaut John Glenn, along with those closest to the Friendship 7 story, revealing previously unknown facts behind one of America’s most ambitious and memorable pioneering space missions.

    1991-10-01

    This year was the third in which LANSCE ran a formal user program. A call for proposals was issued before the scheduled run cycles, and experiment proposals were submitted by scientists from universities, industry, and other research facilities around the world. An external program advisory committee, which LANSCE shares with the Intense Pulsed Neutron Source (IPNS), Argonne National Laboratory examined the proposals and made recommendations. At LANSCE, neutrons are produced by spallation when a pulsed, 800-MeV proton beam impinges on a tungsten target. The proton pulses are provided by the Clinton P. Anderson Meson Physics Facility (LAMPF) accelerator and an associated Proton Storage Ring (PSR), which can alter the intensity, time structure, and repetition rate of the pulses. The LAMPF protons of Line D are shared between the LANSCE target and the Weapons Neutron Research facility, which results in LANSCE spectrometers being available to external users for unclassified research about 80% of each six-month LAMPF run cycle. Measurements of interest to the Los Alamos National Laboratory may also be performed and may occupy up to an additional 20% of the available beam time. These experiments are reviewed by an internal program advisory committee. One hundred thirty-four proposals were submitted for unclassified research and twelve proposals for research of a programmatic nature to the Laboratory. Our definition of beam availability is when the proton current from the PSR exceeds 50% of the planned value. The PSR ran at 65{mu}A current (average) at 20 Hz for most of 1990. All of the scheduled experiments were performed and experiments in support of the LANSCE research program were accomplished during the discretionary periods.

    Brunt, M. R.; Ellins, K. K.; Frohlich, C. A.

    2011-12-01

    In 2008, during my participation in the NSF-sponsored Texas Earth & Space Science (TXESS) Revolution professional development program, I was awarded an AS-1 seismograph through IRIS's Seismographs in Schools Program. This program serves to create an international educational seismic network that allows teachers across the country and around the world to share seismic data in real-time using online tools, classroom activities, and technical support documents for seismic instruments. Soon after receiving my AS-1, I founded and began sponsoring the Eagle Pass Jr. High Seismology Team which consists of selected 7th and 8th grade students. Eagle Pass Jr. High is a Title 1 school that serves a predominantly "at-risk" Hispanic population. We meet after school once a week to learn about earthquakes, seismic waves, analyze recorded seismic event data using computer software programming, and correspond with other students from schools around the country. This team approach has been well received by fellow TXESS Revolution teachers with AS-1 seismographs and will be implemented by David Boyd, STEM coordinator for Williams Preparatory Academy in Dallas, Texas this fall 2011. All earthquakes recorded by our seismograph station (EPTX), which has remained online and actively recording seismic data since 2008, are catalogued and then plotted on a large world map displayed on my classroom wall. A real-time seismogram image updates every five minutes and along with all earthquakes recorded since installation can be viewed on our webpage http://www.iris.edu/hq/ssn/schools/view/eptx. During the 2010-2011 school year, my seismology team and I participated in an earthquake research study led by Dr. Cliff Frohlich at the Institute for Geophysics. The study examined seismograms and felt reports for the 25 April 2010 Alice, Texas, earthquake, in order to investigate its possible connection to oil and gas production in the Stratton oil and gas field.

    1994-09-01

    As the sole renal Na,K-ATPase isozyme, the alpha 1 Na,K-ATPase accounts for all active transport of Na+ throughout the nephron. This role in renal Na+ reabsorption and the primacy of the kidney in hypertension pathogenesis make it a logical candidate gene for salt-sensitive genetic hypertension. An adenine (A)1079-->thymine (T) transversion, resulting in the substitution of glutamine276 with leucine and associated with decreased net 86Rb+ (K+) influx, was identified in Dahl salt-sensitive/JR rat kidney alpha 1 Na,K-ATPase cDNA. However, because a Taq polymerase chain reaction amplification-based reanalysis did not detect the mutant T1079 but rather only the wild-type A1079 alpha 1 Na,K-ATPase allele in Dahl salt-sensitive rat genomic DNA, we reexamined alpha 1 Na,K-ATPase sequences using Taq polymerase error-independent amplification-based analyses of genomic DNA (by polymerase allele-specific amplification and ligase chain reaction analysis) and kidney RNA (by mRNA-specific thermostable reverse transcriptase-polymerase chain reaction analysis). We also performed modified 3' mismatched correction analysis of genomic DNA using an exonuclease-positive thermostable DNA polymerase. All the confirmatory test results were concordant, confirming the A1079-->T transversion in the Dahl salt-sensitive alpha 1 Na,K-ATPase allele and its transcript, as well as the wild-type A1079 sequence in the Dahl salt-resistant alpha 1 Na,K-ATPase allele and its transcript. Documentation of a consistent Taq polymerase error that selectively substituted A at T1079 (sense strand) was obtained from Taq polymerase chain reaction amplification and subsequent cycle sequencing of reconfirmed known Dahl salt-sensitive/JR rat mutant T1079 alpha 1 cDNA M13 subclones. This Taq polymerase error results in the reversion of mutant sequence back to the wild-type alpha 1 Na,K-ATPase sequence. This identifies a site- and nucleotide-specific Taq polymerase misincorporation, suggesting that a structural

    Full Text Available Foregut in D. hominis (Linnaeus Jr., 1781 as the majority of the larval Diptera somatic tissue, is made up of polytenic cells, and grows at the expenses of the polytenization of its nuclei followed by the increase in size of each cell. The oesophagus, of ectodermic origem, is interiorly covered by a chitinous squamous epithelium that rests upon a very thin basal lamina. This sheet is surrounded by thick muscle bundles. The oesophagus intussuscepts the midgut forming the cardia. The cardia, with three epithelial layers: two internal ones, of ectodermal origin and one external of endodermic origin. At the anterior portion of the cardia, between these two types of epithelium, there is a cluster of small, non polytenic cells, forming the imaginal disk of the foregut. Metamoiphosis begins at the end of the larval period with signs of nuclear degeneration of all the polytenic cells, as well as the increase in number of the imaginal disk ones. The oesophagic portion intussuscepted into the cardia, everts; its cells suffer apoptosis and are replaced by the new cells growing from the imaginal disk. The external layer cells also degenerate and are pinched off into the lumen of the very anterior portion of the midgut. The newly formed oesophagus intussuscepts "de novo" to form the two internal layers of the adult cardia. At the same time the midgut regenerative cells grow anteriorly to form the new external layer of the adult cardia.

  17. Between Cultural Memory and Communicative Memory – the Dilemmas of Reconstruction of Annihilated Past of Polish Jews

    Directory of Open Access Journals (Sweden)

    Krzysztof Malicki

    2015-08-01

    Full Text Available This text presents briefly some of the elements of Polish discourse about collective memory of Holocaust during transformations. I refer to Assmann’s concept of communicative and cultural memories, which seems to help to explain the phenomenon of present memory, which can be observed. This text concentrates not on Polish memory of annihilation of Jews (so different from the memory of victims or perpetrators, not to mention different memory of other nations but on its internal divisions and dilemmas which it generates. Along with war generation passing away, the decisive role of creating Polish memory about Shoah will be taken over by specialised institutions and rituals commemorating the past. In the early post -war period the transfer of memory happened mainly by the witness. The role of specialised institutions was marginal. From the beginning of XX century along with last witnesses passing away, the memory of Shoah became the focus of institutions (scientific institutions gathering documents including witnesses’ reports and anniversaries. It is a very important moment to look again at the memory distributed from the roots and confront it with models and standards of commemorating the past, which will create the memory of the next generations.

    A major goal of memory research is to understand how cognitive processes in memory are supported at the level of brain systems and network representations. Especially promising in this direction are new findings in humans and animals that converge in indicating a key role for the hippocampus in the systematic organization of memories. New findings also indicate that the prefrontal cortex may play an equally important role in the active control of memory organization during both encoding and retrieval. Observations about the dialog between the hippocampus and prefrontal cortex provide new insights into the operation of the larger brain system that serves memory. PMID:27687117

    2014-01-01

    Based on the on-site questionnaire survey on tourists at the Whampoa Military Academy Memorial (WMAM),this paper uses the Structural Equation Model (SEM) to assess the effectiveness and mechanism of interpretation in achieving national identity in red attractions. It checks the viability of three mainstream interpretation effectiveness assessment approaches promoted respectively by Lavidge&Stenier (1961),Rokeach& Defleur (1976) and Wagar (1982) in red heritage sites. Data from over 302 tourists’ questionnaire were collected in March 2013. A comprehensive model based on the three approaches has been built and a Structural Equation Model is used for theory testing and development. Empirical results indicate that interpretation may contribute to the formation of national identity of visitors by greatly increasing their historical knowledge, evoking tourists’ patriotism and providing good emotional experience. But the effectiveness of interpretation varied in relation to the types of attractions and conservation goals the tourist sites want to achieve. The study shows that interpretive effectiveness in the WMAM supports Lavidge&Stenier’s effect-structure model, which claims that the influencing process of interpretation follows the sequence from knowledge gain, through emotion or attitude change, to behavior modification. The study also finds that interpretation may have an immediate direct impact on tourists’ behavior changes at the same time. In the information delivering process, knowledge restructuring plays an important role which decides to a large extent the effectiveness of interpretation. The interactive material such as manuals and multimedia systems played a vital role in the effectiveness of interpretive messages in the WMAM. Therefore, red heritage sites should pay more attention to the construction of non-personnel interpretation system and the needs of young tourists to fully exercise its educational functions.%通过对黄埔军校旧址纪念

    The effect of Mo on the abrasive wear resistance of (20-23)Cr-(7-8)Nb hard-faced S355JR steel by shielded metal arc welding (SMAW) was studied. Four types of flux, consisting of fixed Cr and Nb but varying Mo contents, coated on hard-facing electrode were used. Microstructure, micro hardness, and abrasive wear resistance of the hard-faced surface were investigated by ASTM G65 D procedure. The original microstructures consist of the primary coarse and eutectic carbides. Mo affects morphology of carbides by decreasing primary carbide size. When Mo content in the hard-faced surface was up to 6.43 wt.-%, the highest abrasive wear resistance and micro hardness were obtained. The decrease of primary carbide size is attributed to the increased nucleation induced by Mo addition. Network structure was observed when the Mo content reaches 10.19 wt.-%. The main mechanisms of wear are micro-cutting and carbide pulling out. (orig.)

    An analysis of Chandra ACIS data for two relatively bright and narrow portions of the northwestern rim of G266.2-1.2 (a.k.a. RX J0852.0-4622 or Vela Jr.) reveal evidence of a radial displacement of 2.40 +/- 0.56 arcsec between 2003 and 2008. The corresponding expansion rate (0.42 +/- 0.10 arcsec/yr or 13.6 +/- 4.2%/kyr) is about half the rate reported for an analysis of XMM-Newton data from a similar, but not identical, portion of the rim over a similar, but not identical, time interval (0.84 +/- 0.23 arcsec/yr, Katsuda et al. 2008a). If the Chandra rate is representative of the remnant as a whole, then the results of a hydrodynamic analysis suggest that G266.2-1.2 is between 2.4 and 5.1 kyr old if it is expanding into a uniform ambient medium (whether or not it was produced by a Type Ia or Type II event). If the remnant is expanding into the material shed by a steady stellar wind, then the age could be as much as 50% higher. The Chandra expansion rate and a requirement that the shock speed be greater than or...

    Automatic typewriters, transistor radios, microfiche, black and white television…while considered high-tech in the 1950s, these technologies seem limited when viewed from the 21st century. The same is true for cardiovascular medicine, which back then relied on electrocardiograms and X-rays for most diagnoses. In the 60 years since, advances in medical capabilities have progressed at a staggering pace. Patient research that once required months poring over paper charts is now reduced to hours using electronic medical record databases. Diagnostic images that once took days to process can now be accessed instantly through ultrasound and magnetic resonance imaging. While a half-century ago no one would have imagined accessing any and all information with a 5-second Google search, so too would noninvasive heart surgery been considered unimaginable. Since the 1950s when he graduated from medical school, William L. Winters, Jr., has been a first-hand witness to breathtaking innovations in cardiovascular medicine-both globally and in Houston. Author of Houston Hearts: A History of Cardiovascular Surgery and Medicine at Houston Methodist DeBakey Heart & Vascular Center and long-time medical editor of the Methodist DeBakey Cardiovascular Journal, Dr. Winters sat down with the journal editors this past April to share his insights from the last half-century of medical practice.

  5. Memory dynamics under stress.

    Science.gov (United States)

    Quaedflieg, Conny W E M; Schwabe, Lars

    2017-06-19

    Stressful events have a major impact on memory. They modulate memory formation in a time-dependent manner, closely linked to the temporal profile of action of major stress mediators, in particular catecholamines and glucocorticoids. Shortly after stressor onset, rapidly acting catecholamines and fast, non-genomic glucocorticoid actions direct cognitive resources to the processing and consolidation of the ongoing threat. In parallel, control of memory is biased towards rather rigid systems, promoting habitual forms of memory allowing efficient processing under stress, at the expense of "cognitive" systems supporting memory flexibility and specificity. In this review, we discuss the implications of this shift in the balance of multiple memory systems for the dynamics of the memory trace. Specifically, stress appears to hinder the incorporation of contextual details into the memory trace, to impede the integration of new information into existing knowledge structures, to impair the flexible generalisation across past experiences, and to hamper the modification of memories in light of new information. Delayed, genomic glucocorticoid actions might reverse the control of memory, thus restoring homeostasis and "cognitive" control of memory again.

    The purpose of this paper is to show that immunological memory is an associative and robust memory that belongs to the class of sparse distributed memories. This class of memories derives its associative and robust nature by sparsely sampling the input space and distributing the data among many independent agents. Other members of this class include a model of the cerebellar cortex and Sparse Distributed Memory (SDM). First we present a simplified account of the immune response and immunological memory. Next we present SDM, and then we show the correlations between immunological memory and SDM. Finally, we show how associative recall in the immune response can be both beneficial and detrimental to the fitness of an individual.

    Nowicki, Dimitri; Siegelmann, Hava

    2010-06-11

    This paper introduces a new model of associative memory, capable of both binary and continuous-valued inputs. Based on kernel theory, the memory model is on one hand a generalization of Radial Basis Function networks and, on the other, is in feature space, analogous to a Hopfield network. Attractors can be added, deleted, and updated on-line simply, without harming existing memories, and the number of attractors is independent of input dimension. Input vectors do not have to adhere to a fixed or bounded dimensionality; they can increase and decrease it without relearning previous memories. A memory consolidation process enables the network to generalize concepts and form clusters of input data, which outperforms many unsupervised clustering techniques; this process is demonstrated on handwritten digits from MNIST. Another process, reminiscent of memory reconsolidation is introduced, in which existing memories are refreshed and tuned with new inputs; this process is demonstrated on series of morphed faces.

    2009-08-01

    The goal of vaccination is to induce long-lasting protective immune memory. Although most vaccines induce good memory responses, the type of memory induced by different vaccines may be considerably different. In addition, memory responses to the same vaccine may be influenced by age, environmental and genetic factors. Results emerging from detailed and integrated profiling of immune-responses to natural infection or vaccination suggest that the type and duration of immune memory are largely determined by the magnitude and complexity of innate immune signals that imprint the acquired immune primary responses. Here we summarize results obtained from analyzing human immune memory responses to different types of vaccines. We will also discuss how extending clinical investigation to events occurring early after vaccination can help identify early predictive markers of protective memory and thus contribute to faster development of better and safer vaccines.

    The last decades of the twentieth century and the beginning of the new millennium have been marked by a strong focus on the past and, consequently, a proliferation of studies on memory. Perhaps this great attention to memory implies a new way of thinking and experiencing time and space, two categories that deeply changed by the phenomenon of cultural globalization (Huyssen, 2003). If it is true that with new technologies, space and time have been dramatically compressed, it is also true that the horizons of our imagination have expanded to dimensions of space and time which are able to cross the boundaries of a locally circumscribed vision. So our past and our memory no longer have clear and delimited boundaries which were established by a tradition with local and national roots within specific geographical borders. The revival of studies on memory has included large Italian catastrophes occurred in the last centuries. Several initiatives, researches, exhibitions and commemorations wanted to remember these great catastrophes of our country. What is the relationship between these initiatives and the reduction of risk? What relationships are there between memory, forgetting and risk? On the issue of risk reduction the provocative phrase of Pierre Nora fits well: "We talk about memory because it no longer exists "? (Pierre Nora, Les Lieux de mémoire, Gallimard 1997). A direction to work on is indicated by Aleida Assmann (1999) that associates the idea of crisis of memory with the crisis of "living memory", that is linked to the disappearance of the eyewitnesses of the greatest tragedies of the twentieth century. When the generations who lived through L'Aquila earthquake on 6 April 2009 will die, the memory of the earthquake will vanish with them? To answer these questions and to propose communication and educational strategies capable of persisting the passage of generations, this work explores an interdisciplinary point of view, which takes into account recent

  15. Psychophysiology of prospective memory.

    Science.gov (United States)

    Rothen, Nicolas; Meier, Beat

    2014-01-01

    Prospective memory involves the self-initiated retrieval of an intention upon an appropriate retrieval cue. Cue identification can be considered as an orienting reaction and may thus trigger a psychophysiological response. Here we present two experiments in which skin conductance responses (SCRs) elicited by prospective memory cues were compared to SCRs elicited by aversive stimuli to test whether a single prospective memory cue triggers a similar SCR as an aversive stimulus. In Experiment 2 we also assessed whether cue specificity had a differential influence on prospective memory performance and on SCRs. We found that detecting a single prospective memory cue is as likely to elicit a SCR as an aversive stimulus. Missed prospective memory cues also elicited SCRs. On a behavioural level, specific intentions led to better prospective memory performance. However, on a psychophysiological level specificity had no influence. More generally, the results indicate reliable SCRs for prospective memory cues and point to psychophysiological measures as valuable approach, which offers a new way to study one-off prospective memory tasks. Moreover, the findings are consistent with a theory that posits multiple prospective memory retrieval stages.

    Reliability is of great concern to the scalability of extreme-scale systems. Of particular concern are soft errors in main memory, which are a leading cause of failures on current systems and are predicted to be the leading cause on future systems. While great effort has gone into designing algorithms and applications that can continue to make progress in the presence of these errors without restarting, the most critical software running on a node, the operating system (OS), is currently left relatively unprotected. OS resiliency is of particular importance because, though this software typically represents a small footprint of a compute node's physical memory, recent studies show more memory errors in this region of memory than the remainder of the system. In this paper, we investigate the soft error vulnerability of two operating systems used in current and future high-performance computing systems: Kitten, the lightweight kernel developed at Sandia National Laboratories, and CLE, a high-performance Linux-based operating system developed by Cray. For each of these platforms, we outline major structures and subsystems that are vulnerable to soft errors and describe methods that could be used to reconstruct damaged state. Our results show the Kitten lightweight operating system may be an easier target to harden against memory errors due to its smaller memory footprint, largely deterministic state, and simpler system structure.

    (15810) 1994 JR1, a 3:2 resonant Kupier Belt Object (KBO), was observed by NASA's New Horizons spacecraft using the LOng Range Reconnaissance Imager (LORRI) on November 2, 2015 from a distance of 1.85 AU, and again on April 7, 2016 from a distance of 0.71 AU. These were the first close observations of any KBO other than Pluto, and the first ever of a small KBO at close range. Combining ground-based and HST observations at small phase angles and the LORRI observations at higher phase angles, we produced the first disk-integrated solar phase curve of a typical in-situ KBO from 0.6 to 58 degrees phase angle. Observations at these geometries, a range only attainable using a spacecraft in the outer Solar System, constrain surface properties such as macroscopic roughness and the single particle phase function. 1994 JR1 has a rough surface with a 37 +/- 5 degrees mean topographic slope angle and has a relatively rapid rotation period of 5.47 +/- 0.33 hours, with a lightcurve amplitude of 0.8 magnitudes from the spacecraft. 1994 JR1 is currently 2.7 AU from Pluto; our astrometric points enable high-precision orbit determination and integrations which show that it comes this close to Pluto every 2.4 million years (10,000 heliocentric orbits), causing Pluto to perturb 1994 JR1. During the November spacecraft observation, the KBO was simultaneously observed using the Hubble Space Telescope in two colors, confirming its very red spectral slope. These observations have laid the groundwork for numerous potential future distant KBO observations in the proposed New Horizons-Kuiper Belt Extended Mission.

  19. Human learning and memory.

    Science.gov (United States)

    Johnson, M K; Hasher, L

    1987-01-01

    There have been several notable recent trends in the area of learning and memory. Problems with the episodic/semantic distinction have become more apparent, and new efforts have been made (exemplar models, distributed-memory models) to represent general knowledge without assuming a separate semantic system. Less emphasis is being placed on stable, prestored prototypes and more emphasis on a flexible memory system that provides the basis for a multitude of categories or frames of reference, derived on the spot as tasks demand. There is increasing acceptance of the idea that mental models are constructed and stored in memory in addition to, rather than instead of, memorial representations that are more closely tied to perceptions. This gives rise to questions concerning the conditions that permit inferences to be drawn and mental models to be constructed, and to questions concerning the similarities and differences in the nature of the representations in memory of perceived and generated information and in their functions. There has also been a swing from interest in deliberate strategies to interest in automatic, unconscious (even mechanistic!) processes, reflecting an appreciation that certain situations (e.g. recognition, frequency judgements, savings in indirect tasks, aspects of skill acquisition, etc) seem not to depend much on the products of strategic, effortful or reflective processes. There is a lively interest in relations among memory measures and attempts to characterize memory representations and/or processes that could give rise to dissociations among measures. Whether the pattern of results reflects the operation of functional subsystems of memory and, if so, what the "modules" are is far from clear. This issue has been fueled by work with amnesics and has contributed to a revival of interaction between researchers studying learning and memory in humans and those studying learning and memory in animals. Thus, neuroscience rivals computer science as a

C., included remembrances from astronauts and friends, an excerpt from President John Kennedy's 1962 “We choose to go to the Moon” speech, and a somber rendition of the jazz standard “Fly Me to the Moon.” NASA administrator Charles Bolden said that Armstrong, commander of NASA's Apollo 11 mission, “left a foundation for the future and paved the way for future American explorers to be first to step foot on Mars or another planet. Today, let us recommit ourselves to this grand challenge in honor of the man who first demonstrated it was possible to reach new worlds—and whose life demonstrated the quiet resolve and determination that makes every new, more difficult step into space possible.”

  1. Quantum Associative Memory

    1998-01-01

    This paper combines quantum computation with classical neural network theory to produce a quantum computational learning algorithm. Quantum computation uses microscopic quantum level effects to perform computational tasks and has produced results that in some cases are exponentially faster than their classical counterparts. The unique characteristics of quantum theory may also be used to create a quantum associative memory with a capacity exponential in the number of neurons. This paper combines two quantum computational algorithms to produce such a quantum associative memory. The result is an exponential increase in the capacity of the memory when compared to traditional associative memories such as the Hopfield network. The paper covers necessary high-level quantum mechanical and quantum computational ideas and introduces a quantum associative memory. Theoretical analysis proves the utility of the memory, and it is noted that a small version should be physically realizable in the near future.

    This article is a continuous dialogue on memory triggered by Brockmeier’s (2010) article. I drift away from the conventionalization of the archive as a spatial metaphor for memory in order to consider the greater possibility of “time” for conceptualizing memory. The concept of time is central...... in terms of autobiographical memory. The second category of time is discussed, drawing on Augustine and Bergson amongst others. Bergson’s notion of duration has been considered as a promising concept for a better understanding of autobiographical memory. Psychological phenomena such as autobiographical...... memory should embrace not only spatial dimension, but also a temporal dimension, in which a constant flow of irreversible time, where multiplicity, momentarily, dynamic stability and becoming and emergence of novelty can be observed....

    Memory for antigen is a defining feature of adaptive immunity. Antigen-specific lymphocyte populations show an increase in number and function after antigen encounter and more rapidly re-expand upon subsequent antigen exposure. Studies of immune memory have primarily focused on effector B cells and T cells with microbial specificity, using prime challenge models of infection. However, recent work has also identified persistently expanded populations of antigen-specific regulatory T cells that protect against aberrant immune responses. In this Review, we consider the parallels between memory effector T cells and memory regulatory T cells, along with the functional implications of regulatory memory in autoimmunity, antimicrobial host defence and maternal fetal tolerance. In addition, we discuss emerging evidence for regulatory T cell memory in humans and key unanswered questions in this rapidly evolving field. PMID:26688349

    Both the discovery of the x-ray and the founding of the National Medical Association (NMA) occurred in 1895. Radiologists have participated importantly in the NMA since the lecture of Dr Marcus F. Wheatland at the 1909 Annual Meeting in Boston, Massachusetts, which led to his election as president of the NMA for the following year. More recently, Dr Tracy M. Walton was president of the NMA in its centennial year. This article details early and continued participation in the NMA by radiologists, including the founding of the Section on Radiology in 1949, with its first chairman, Dr William E.

    Full Text Available Self and mind are constituted with the cumulative effects of significant life events. This description is regarded as a given explicitly or implicitly in vari-ous theories of personality. Such an acknowledgment inevitably brings together these theories on two basic concepts. The first one is the emotions that give meaning to experiences and the second one is the memory which is related to the storage of these experiences. The part of the memory which is responsible for the storage and retrieval of life events is the autobiographical memory. Besides the development of personality, emotions and autobiographical memory are important in the development of and maintenance of psychopathology. Therefore, these two concepts have both longitudinal and cross-sectional functions in understanding human beings. In case of psychopathology, understanding emotions and autobiographical memory developmentally, aids in understanding the internal susceptibility factors. In addition, understanding how these two structures work and influence each other in an acute event would help to understand the etiological mechanisms of mental disorders. In the literature, theories that include both of these structures and that have clinical implications, are inconclusive. Theories on memory generally focus on cognitive and semantic structures while neglecting emotions, whereas theories on emotions generally neglect memory and its organization. There are only a few theories that cover both of these two concepts. In the present article, these theories that include both emotions and autobiographical memory in the same framework (i.e. Self Memory System, Associative Network Theory, Structural and Contextual theories and Affect Regulation Theory were discussed to see the full picture. Taken together, these theories seem to have the potential to suggest data-driven models in understanding and explaining symptoms such as flashbacks, dissociation, amnesia, over general memory seen in

We also create representations of minds in order to understand the emotions that artworks express.

    Full Text Available This article exposes the hypothesis that memory artifacts, created to commemorate the victims of armed conflict in Colombia, are an expression of the underground memories and a way of political action in the midst of war. We analyze three cases of creations of memory artifacts in Medellín, Colombia, as forms of suffering, perceiving and resisting the power of armed groups in Medellín. The silence, inherent in these objects, should not be treated as an absence of language, but as another form of expression of memory. Silence is a tactic used to overcome losses and reset everyday life in contexts of protracted violence.

  15. The future of memory

    Marinella, M.

    In the not too distant future, the traditional memory and storage hierarchy of may be replaced by a single Storage Class Memory (SCM) device integrated on or near the logic processor. Traditional magnetic hard drives, NAND flash, DRAM, and higher level caches (L2 and up) will be replaced with a single high performance memory device. The Storage Class Memory paradigm will require high speed ( 1012), nonvolatility (retention > 10 years), and low switching energies (Technology Roadmap for Semiconductors (ITRS) has recently evaluated several potential candidates SCM technologies, including Resistive (or Redox) RAM, Spin Torque Transfer RAM (STT-MRAM), and phase change memory (PCM). All of these devices show potential well beyond that of current flash technologies and research efforts are underway to improve the endurance, write speeds, and scalabilities to be on-par with DRAM. This progress has interesting implications for space electronics: each of these emerging device technologies show excellent resistance to the types of radiation typically found in space applications. Commercially developed, high density storage class memory-based systems may include a memory that is physically radiation hard, and suitable for space applications without major shielding efforts. This paper reviews the Storage Class Memory concept, emerging memory devices, and possible applicability to radiation hardened electronics for space.

  17. Awareness of memory deficits in early stage Huntington's disease.

    Directory of Open Access Journals (Sweden)

    Laurent Cleret de Langavant

    Full Text Available Patients with Huntington's disease (HD are often described as unaware of their motor symptoms, their behavioral disorders or their cognitive deficits, including memory. Nevertheless, because patients with Parkinson's disease (PD remain aware of their memory deficits despite striatal dysfunction, we hypothesize that early stage HD patients in whom degeneration predominates in the striatum can accurately judge their own memory disorders whereas more advanced patients cannot. In order to test our hypothesis, we compared subjective questionnaires of memory deficits (in HD patients and in their proxies and objective measures of memory dysfunction in patients. Forty-six patients with manifest HD attending the out-patient department of the French National Reference Center for HD and thirty-three proxies were enrolled. We found that HD patients at an early stage of the disease (Stage 1 were more accurate than their proxies at evaluating their own memory deficits, independently from their depression level. The proxies were more influenced by patients' functional decline rather than by patients' memory deficits. Patients with moderate disease (Stage 2 misestimated their memory deficits compared to their proxies, whose judgment was nonetheless influenced by the severity of both functional decline and depression. Contrasting subjective memory ratings from the patients and their objective memory performance, we demonstrate that although HD patients are often reported to be unaware of their neurological, cognitive and behavioral symptoms, it is not the case for memory deficits at an early stage. Loss of awareness of memory deficits in HD is associated with the severity of the disease in terms of CAG repeats, functional decline, motor dysfunction and cognitive impairment, including memory deficits and executive dysfunction.

    Danion, J M; Peretti, S; Gras-Vincendon, A; Singer, L

    1992-01-01

    The current interest in memory disorders in schizophrenia results from the way perceptions of schizophrenia--whose organic origin is becoming increasingly evident--and memory--according to which there exist not one, but several memories--have developed. Memory disorders in the schizophrenic cannot be considered in isolation from knowledge accumulated in other areas of the cognitive and neuro-sciences; a more detailed understanding of these disorders requires a comparison of the different cognitive approaches, both with each other and with the neurobiological and clinical approaches, so that they can be integrated. Despite numerous methodological and conceptual difficulties, it now appears to have been established that the schizophrenic's memory deficit should be seen in the context of a wider cognitive deficit, that the memory tasks are not all disturbed and that the memory deficit cannot be identified with one specific form of memory. Thus, iconic formation, short-term memory in the traditionally accepted sense and implicit memory are hardly, if at all, affected; in contrast, the early processing of information, working memory and explicit memory are disturbed, probably to the extent that they require the implementation of strategies to organise the information to be memorized. Finally, in certain tasks, such as those evaluating latent inhibition or negative priming, schizophrenics perform better than normal subjects, suggesting that schizophrenics' cognitive deficit is localised. This profile of memory disorders is compatible with a dysfunction predominating in the frontal and temporo-hippocampal regions. Neuroleptics and anticholinergics have opposite effects on cognitive and mnesic performance, which is improved by the former and aggravated by the latter. The influence of clinical symptoms, positive or negative, institutionalisation of patients and chronic tardive dyskinesia is unclear. Among the theoretical proposals put forward to account for the observed

    A large number of questions in clinical and/or experimental neuropsychology require the multiple repetition of memory tests at relatively short intervals. Studies on the impact of the associated exercise and interference effects on the validity of the test results are rare. Moreover, hardly any neuropsychological instruments exist to date to record the memory performance with several parallel versions in which the emotional valence of the test material is also taken into consideration. The aim of the present study was to test whether a working memory test (WST, a digit-span task with neutral or negative distraction stimuli) devised by our workgroup can be used with repeated measurements. This question was also examined in parallel versions of a wordlist learning paradigm and an autobiographical memory test (AMT). Both tests contained stimuli with neutral, positive and negative valence. Twenty-four participants completed the memory testing including the working memory test and three versions of a wordlist and the AMT at intervals of a week apiece (measuring points 1. - 3.). The results reveal consistent performances across the three measuring points in the working and autobiographical memory test. The valence of the stimulus material did not influence the memory performance. In the delayed recall of the wordlist an improvement in memory performance over time was seen. The tests on working memory presented and the parallel versions for the declarative and autobiographical memory constitute informal economic instruments within the scope of the measurement repeatability designs. While the WST and AMT are appropriate for study designs with repeated measurements at relatively short intervals, longer intervals might seem more favourable for the use of wordlist learning paradigms. © Georg Thieme Verlag KG Stuttgart · New York.

  6. Bipolar spectral associative memories.

    Science.gov (United States)

    Spencer, R G

    2001-01-01

    Nonlinear spectral associative memories are proposed as quantized frequency domain formulations of nonlinear, recurrent associative memories in which volatile network attractors are instantiated by attractor waves. In contrast to conventional associative memories, attractors encoded in the frequency domain by convolution may be viewed as volatile online inputs, rather than nonvolatile, off-line parameters. Spectral memories hold several advantages over conventional associative memories, including decoder/attractor separability and linear scalability, which make them especially well suited for digital communications. Bit patterns may be transmitted over a noisy channel in a spectral attractor and recovered at the receiver by recurrent, spectral decoding. Massive nonlocal connectivity is realized virtually, maintaining high symbol-to-bit ratios while scaling linearly with pattern dimension. For n-bit patterns, autoassociative memories achieve the highest noise immunity, whereas heteroassociative memories offer the added flexibility of achieving various code rates, or degrees of extrinsic redundancy. Due to linear scalability, high noise immunity and use of conventional building blocks, spectral associative memories hold much promise for achieving robust communication systems. Simulations are provided showing bit error rates for various degrees of decoding time, computational oversampling, and signal-to-noise ratio.

  8. [Learning and memory].

    Science.gov (United States)

    Lombroso, Paul

    2004-09-01

    Memory is broadly divided into declarative and nondeclarative forms of memory. The hippocampus is required for the formation of declarative memories, while a number of other brain regions including the striatum, amygdala and nucleus accumbens are involved in the formation of nondeclarative memories. The formation of all memories require morphological changes of synapses: new ones must be formed or old ones strengthened. These changes are thought to reflect the underlying cellular basis for persistent memories. Considerable advances have occurred over the last decade in our understanding of the molecular bases of how these memories are formed. A key regulator of synaptic plasticity is a signaling pathway that includes the mitogen activated protein (MAP) kinase. As this pathway is required for normal memory and learning, it is not surprising that mutations in members of this pathway lead to disruptions in learning. Neurofibromatosis, Coffin-Lowry syndrome and Rubinstein-Taybi syndrome are three examples of developmental disorders that have mutations in key components of the MAP kinase signaling pathway.

    Crystal, Jonathon D

    2016-01-01

    Source memory is the aspect of episodic memory that encodes the origin (i.e., source) of information acquired in the past. Episodic memory (i.e., our memories for unique personal past events) typically involves source memory because those memories focus on the origin of previous events. Source memory is at work when, for example, someone tells a favorite joke to a person while avoiding retelling the joke to the friend who originally shared the joke. Importantly, source memory permits differentiation of one episodic memory from another because source memory includes features that were present when the different memories were formed. This article reviews recent efforts to develop an animal model of source memory using rats. Experiments are reviewed which suggest that source memory is dissociated from other forms of memory. The review highlights strengths and weaknesses of a number of animal models of episodic memory. Animal models of source memory may be used to probe the biological bases of memory. Moreover, these models can be combined with genetic models of Alzheimer's disease to evaluate pharmacotherapies that ultimately have the potential to improve memory.

    Greater knowledge of the human brain has enabled us to begin devising therapies to rescue or modify memory for the afflicted, such as Alzheimer's patients or post-traumatic stress disorder victims. This same knowledge could also allow us to alter how normal, healthy memory operates; we may become able to enhance memory and learning through biological intervention. But the brain consists of complex, interactive networks, and unintended consequences could easily occur. Moreover, memory is woven into our individuality. Altering our memory processes therefore risks altering us fundamentally. We may not be able to resist opening this neuroscientific Pandora's Box, John Gabrieli writes, but we must proceed with all the wisdom we can muster.

    Memory encoding occurs rapidly, but the consolidation of memory in the neocortex has long been held to be a more gradual process. We now report, however, that systems consolidation can occur extremely quickly if an associative "schema" into which new information is incorporated has previously been created. In experiments using a hippocampal-dependent paired-associate task for rats, the memory of flavor-place associations became persistent over time as a putative neocortical schema gradually developed. New traces, trained for only one trial, then became assimilated and rapidly hippocampal-independent. Schemas also played a causal role in the creation of lasting associative memory representations during one-trial learning. The concept of neocortical schemas may unite psychological accounts of knowledge structures with neurobiological theories of systems memory consolidation.

In laboratory rodents, there is extensive evidence that epinephrine influences memory processing through an inverted-U relationship, at which moderate levels enhance and high levels impair memory. These effects are, in large part, mediated by increases in blood glucose levels subsequent to epinephrine release, which then provide support for the brain processes engaged by learning and memory. These brain processes include augmentation of neurotransmitter release and of energy metabolism, the latter apparently including a key role for astrocytic glycogen. In addition to up- and down-regulation of learning and memory in general, physiological concomitants of emotion and arousal can also switch the neural system that controls learning at a particular time, at once improving some attributes of learning and impairing others in a manner that results in a change in the strategy used to solve a problem.

    The "memory effect" is the permanent change in the relative separation of test particles resulting from the passage of gravitational radiation. We investigate the memory effect for a general, spatially flat Friedmann-Lemaître-Robertson-Walker (FLRW) cosmology by considering the radiation associated with emission events involving particle-like sources. We find that if the resulting perturbation is decomposed into scalar, vector, and tensor parts, only the tensor part contributes to memory. Furthermore, the tensor contribution to memory depends only on the cosmological scale factor at the source and observation events, not on the detailed expansion history of the universe. In particular, for sources at the same luminosity distance, the memory effect in a spatially flat FLRW spacetime is enhanced over the Minkowski case by a factor of (1 +z ).

    Memory T cells are usually considered to be a feature of a successful immune response against a foreign antigen, and such cells can mediate potent immunity. However, in mice, alternative pathways have been described, through which naïve T cells can acquire the characteristics and functions of memory T cells without encountering specific foreign antigen or the typical signals required for conventional T cell differentiation. Such cells reflect a response to the internal rather the external environment, and hence such cells are called innate memory T cells. In this review, we describe how innate memory subsets were identified, the signals that induce their generation and their functional properties and potential role in the normal immune response. The existence of innate memory T cells in mice raises questions about whether parallel populations exist in humans, and we discuss the evidence for such populations during human T cell development and differentiation.

  5. Russell on Memory

    Directory of Open Access Journals (Sweden)

    Thomas Baldwin

    2001-12-01

    Full Text Available Russell famously propounded scepticism about memory in The Analysis of Mind (1921. As he there acknowledged, one way to counter this sceptical position is to hold that memory involves direct acquaintance with past, and this is in fact a thesis Russell had advanced in The Problems of Philosophy (1911. Indeed he had there used the case of memory to develop a sophisticated falibilist, non-sceptical, epistemology. By 1921, however, Russell had rejected the early conception of memory as incompatible with the neutral monism he now affirmed. In its place he argued that memory involves a distinctive type of belief whose content is given by imagery. Russell's language here is off-putting but without much distortion his later position can be interpreted as an early formulation of a functionalist theory of mind based on a causal theory of mental representation. Thus interpreted it provides the basis for a different response to Russell's sceptical thesis.

    The serotonin transporter (SERT) has been associated to diverse functions and diseases, though seldom to memory. Therefore, we made an attempt to summarize and discuss the available publications implicating the involvement of the SERT in memory, amnesia and anti-amnesic effects. Evidence indicates that Alzheimer's disease and drugs of abuse like d-methamphetamine (METH) and (+/-)3,4-methylenedioxymethamphetamine (MDMA, "ecstasy") have been associated to decrements in the SERT expression and memory deficits. Several reports have indicated that memory formation and amnesia affected the SERT expression. The SERT expression seems to be a reliable neural marker related to memory mechanisms, its alterations and potential treatment. The pharmacological, neural and molecular mechanisms associated to these changes are of great importance for investigation.

    2010-01-01

    We understand the dynamics of the world around us as by associating pairs of events, where one event has some influence on the other. These pairs of events can be aggregated into a web of memories representing our understanding of an episode of history. The events and the associations between them need not be directly experienced-they can also be acquired by communication. In this paper we take a network approach to study the dynamics of memories of history. First we investigate the network structure of a data set consisting of reported events by several individuals and how associations connect them. We focus our measurement on degree distributions, degree correlations, cycles (which represent inconsistencies as they would break the time ordering) and community structure. We proceed to model effects of communication using an agent-based model. We investigate the conditions for the memory webs of different individuals to converge to collective memories, how groups where the individuals have similar memories (b...

    2016-08-01

    Although memories about a nation's past usually are semantic in nature, a distinction needs to be made between lived and distant semantic collective memories. The former refers to memories of community-relevant events occurring during the lifetime of the rememberer, whereas the latter to memories of distant events. Does the content of lived and distant semantic collective memories differ? Employing both free and cued recall, we examined the memories of younger and older Argentines of the Military Junta of 1976. We also examined the effects of political ideology. Content analysis indicated that (1) lived semantic collective memories were more likely to contain personal recollections than distant semantic collective memories, even though those with distant semantic collective memories could have incorporated memories of the parent's personal experience in their recollections, (2) lived semantic collective memories contained more causal statements, and (3) those on the Right with distant semantic collective memories were more likely to claim that they "Don't know" or offer positive accounts of the Junta, suggesting a need to "defend" the reputation of those on the Right. The results are discussed in terms of the goals and plans different generations might have when recollecting their nation's past.

    Learning outcomes are associated with a variety of environmental and cognitive factors, and the aim of the current study was to compare the predictive power of these factors in longitudinal outcomes. We recruited children in kindergarten and tested their learning outcomes 2 years later. In kindergarten, children completed tests of IQ, phonological awareness, and memory (sentence memory, short-term memory, and working memory). After 2 years, they took national assessments in reading, writing, and math. Working memory performance was not affected by socioeconomic status (SES), whereas IQ, phonological awareness, and sentence memory scores differed as a function of SES. A series of hierarchical regression analyses indicated that working memory and phonological awareness were better predictors of learning than any other factors tested, including SES. Educational implications include providing intervention during the early years to boost working memory and phonological awareness so as to prevent subsequent learning difficulties.

    This study evaluated effects of a key session from a nationally recognized drug abuse prevention program on basic memory processes in 211 high-risk youth in Southern California. In a randomized, between-subject design, the authors manipulated assignment to a Myth and Denial program session and the time of assessment (immediate vs. one-week delay). The authors examined program decay effects on memory accessibility and judgment errors. Those participants exposed to the program session generated more myths and facts from the program than those in the control group, suggesting that even a single program session influenced students’ memory for program information and this was retained at least one week and detectable with indirect tests of memory accessibility. However, consistent with basic research perspectives, participants in the program delayed assessment group erroneously generated more fact-related information from the session to the prompt “It is a myth that_____” than the participants in the program immediate assessment group; that is, they retained more facts as myths. These types of program effects, anticipated by basic memory theory, were not detected with a traditional judgment task in the present sample. The results suggest that basic science approaches offer a novel way of conceptually recasting prevention effects to more completely understand how these effects may operate. Implications for program evaluation and conceptualization are discussed. PMID:22544598

    2014-11-01

    Full Text Available Memory, in particular collective memory, is a process of recording historical events, social changes, as well as identity features of a nation. Memory gets its definition with dance, too. These memory composites are most commonly created with the purpose of highlighting a distinct feature, especially when talking about national memory. Although kinesthetic composition, unlike verbal, is more complex to formulate, standardize and interpret, it has yet created impressive representatives in the field of national culture. One of the most significant and most commonly used symbols of Macedonian identity in the years following establishment of Socialist Republic Macedonia, is the folk dance Teshkoto. It has been used as a repeated emblem in art (literature, painting, sculpturing, music, thus becoming famous countrywide and turning into an idiom of identity. Teshkoto is an example where the very title, as well as the manner of performance, establishes a matrix that is identified with presentation of various historical stages and processes, the Macedonians’ hardships and struggle throughout the centuries. Unlike this example, we have recently been witnessing a process of stressing the Macedonians’ historical antique background, a process that is characterized with taking new direction towards different national memory constructs. These new ways highlight a completely new aspect of the identity composite, and that is the extraordinary heroism of the heroes presented, i.e. the representatives of Macedonian national history. This trend of introduction of new traits of the nation started with a majority of sculptures, dances, which were erected at the most frequented parts of the capital of Macedonia. The new trend is presented with figures that feature warlike and victorious spirit. This new way of looking at these things was gradually transmitted to dance as well. There are already a few dance pieces inspired by the great Macedonian warrior, Alexander

    The characteristics of the memory of accelerated motion in Minkowski spacetime are discussed within the framework of the nonlocal theory of accelerated observers. Two types of memory are distinguished: kinetic and dynamic. We show that only kinetic memory is acceptable, since dynamic memory leads to divergences for nonuniform accelerated motion.

    1991-01-01

    A model for a class of high-capacity associative memories is presented. Since they are based on two-layer recurrent neural networks and their operations depend on the correlation measure, these associative memories are called recurrent correlation associative memories (RCAMs). The RCAMs are shown to be asymptotically stable in both synchronous and asynchronous (sequential) update modes as long as their weighting functions are continuous and monotone nondecreasing. In particular, a high-capacity RCAM named the exponential correlation associative memory (ECAM) is proposed. The asymptotic storage capacity of the ECAM scales exponentially with the length of memory patterns, and it meets the ultimate upper bound for the capacity of associative memories. The asymptotic storage capacity of the ECAM with limited dynamic range in its exponentiation nodes is found to be proportional to that dynamic range. Design and fabrication of a 3-mm CMOS ECAM chip is reported. The prototype chip can store 32 24-bit memory patterns, and its speed is higher than one associative recall operation every 3 mus. An application of the ECAM chip to vector quantization is also described.

    The conventional gravitational memory effect is a relative displacement in the position of two detectors induced by radiative energy flux. We find a new type of gravitational ‘spin memory’ in which beams on clockwise and counterclockwise orbits acquire a relative delay induced by radiative angular momentum flux. It has recently been shown that the displacement memory formula is a Fourier transform in time of Weinberg’s soft graviton theorem. Here we see that the spin memory formula is a Fourier transform in time of the recently-discovered subleading soft graviton theorem.

    2015-02-01

    Education and related proxies for cognitive reserve (CR) are confounded by associations with environmental factors that correlate with cerebrovascular disease possibly explaining discrepancies between studies examining their relationships to cognitive aging and dementia. In contrast, sex-related memory differences may be a better proxy. Since they arise developmentally, they are less likely to reflect environmental confounds. Women outperform men on verbal and men generally outperform women on visuospatial memory tasks. Furthermore, memory declines during the preclinical stage of AD, when it is clinically indistinguishable from normal aging. To determine whether CR mitigates age-related memory decline, we examined the effects of gender and APOE genotype on longitudinal memory performances. Memory decline was assessed in a cohort of healthy men and women enriched for APOE ɛ4 who completed two verbal [Rey Auditory Verbal Learning Test (AVLT), Buschke Selective Reminding Test (SRT)] and two visuospatial [Rey-Osterrieth Complex Figure Test (CFT), and Benton Visual Retention Test (VRT)] memory tests, as well as in a separate larger and older cohort [National Alzheimer's Coordinating Center (NACC)] who completed a verbal memory test (Logical Memory). Age-related memory decline was accelerated in APOE ɛ4 carriers on all verbal memory measures (AVLT, p=.03; SRT pdifferences were retained over time, but no sex differences in rate of decline were found for any measure in either cohort. Sex-based memory advantage does not mitigate age-related memory decline in either APOE ɛ4 carriers or non-carriers.

Health, medication, selfcare and social activity were also measured. Results show that although Raven's score was the best predictor of memory test performance, it had a high refusal rate. Age was not a significant predictor of overall memory test score but results were complicated by age of entry into Part III, with older people performing better on some items. Medication, in particular drugs acting on the central nervous system, enhanced performance on some items.

    2016-01-01

    Full Text Available Under what conditions do countries and cultures considered radically different find a basis for allegiance and kinship? What part does memory play in this process? This article responds to these questions in two ways: 1 Through Emmanuel Levinas and Hannah Arendt, I propose that when an other appears in empathetic discourses that both honor difference and cite shared human experiences, seemingly irreconcilable people can develop a sense of mutual responsibility and 2 Conglomerate memory, memories that fuse together others through common pains, contributes to such an appearance. To illustrate this point, I turn to Congolese voices as they are articulated in online American discourses; although currently, authors of online texts typically rely on traditional narrative forms that position Central Africa as incommensurate to Western civilizations, the Internet's worldwide accessibility and intertextual capacities render it a place primed for developing international collectives by connecting memories while maintaining difference.

    Accurate immunological models offer the possibility of performing highthroughput experiments in silico that can predict, or at least suggest, in vivo phenomena. In this chapter, we compare various models of immunological memory. We first validate an experimental immunological simulator, developed by the authors, by simulating several theories of immunological memory with known results. We then use the same system to evaluate the predicted effects of a theory of immunological memory. The resulting model has not been explored before in artificial immune systems research, and we compare the simulated in silico output with in vivo measurements. Although the theory appears valid, we suggest that there are a common set of reasons why immunological memory models are a useful support tool; not conclusive in themselves.

    We report a new type of racetrack memory based on current-controlled movement of magnetic vortices in magnetic nanowires with rectangular cross-section and weak perpendicular anisotropy. Data are stored through the core polarity of vortices and each vortex carries a data bit. Besides high density, non-volatility, fast data access, and low power as offered by domain wall racetrack memory, magnetic vortex racetrack memory has additional advantages of no need for constrictions to define data bits, changeable information density, adjustable current magnitude for data propagation, and versatile means of ultrafast vortex core switching. By using micromagnetic simulations, current-controlled motion of magnetic vortices in cobalt nanowire is demonstrated for racetrack memory applications.

    In this paper we present universal broadband multiresonator quantum memory based on the spatial-frequency combs of the microresonators coupled with a common waveguide. We find a Bragg-type impedance matching condition for the coupling of the microresonators with a waveguide field that provides an efficient broadband quantum storage. The analytical solution obtained for the microresonator fields enables sustainable parametric control of all the memory characteristics. We also construct an experimental prototype of the studied quantum memory in the microwave spectral range that demonstrates basic properties of the microwave microresonators, their coupling with a common waveguide, and independent control of the microresonator frequencies. Experimentally observed narrow lines of the microresonators confirm the possibility of multiresonator quantum memory implementation.

  3. Memory Circuit Fault Simulator

    2013-01-01

    Spacecraft are known to experience significant memory part-related failures and problems, both pre- and postlaunch. These memory parts include both static and dynamic memories (SRAM and DRAM). These failures manifest themselves in a variety of ways, such as pattern-sensitive failures, timingsensitive failures, etc. Because of the mission critical nature memory devices play in spacecraft architecture and operation, understanding their failure modes is vital to successful mission operation. To support this need, a generic simulation tool that can model different data patterns in conjunction with variable write and read conditions was developed. This tool is a mathematical and graphical way to embed pattern, electrical, and physical information to perform what-if analysis as part of a root cause failure analysis effort.

    The ability to store and later use information is essential for a variety of adaptive behaviors, including integration, learning, generalization, prediction and inference. In this Review, we survey theoretical principles that can allow the brain to construct persistent states for memory. We identify requirements that a memory system must satisfy and analyze existing models and hypothesized biological substrates in light of these requirements. We also highlight open questions, theoretical puzzles and problems shared with computer science and information theory.

    After several decades pushing the technology and the development of the world, the electronics is giving space for technologies that use light. We propose and analyze an optical memory embedded in a nonlinear photonic crystal (PhC), whose system of writing and reading data is controlled by an external command signal. This optical memory is based on optical directional couplers connected to a shared optical ring. Such a device can work over the C-Band of ITU (International Telecommunication Union).

    Epigenetics refers to heritable changes in patterns of gene expression that occur without alterations in DNA sequence. The epigenetic mechanisms involve covalent modifications of DNA and histones, which affect transcriptional activity of chromatin. Since chromatin states can be propagated through mitotic and meiotic divisions, epigenetic mechanisms are thought to provide heritable 'cellular memory'. Here, we review selected examples of epigenetic memory in plants and briefly discuss underlying mechanisms.

    A resistive memory network that has no crossover wiring is proposed to overcome the hardware limitations to size and functional complexity that is associated with conventional analogue neural networks. The proposed memory network is based on simple network cells that are arranged in a hierarchical modular architecture. Cognitive functionality of this network is demonstrated by an example of character recognition. The network is trained by an evolutionary process to completely recognise characters deformed by random noise, rotation, scaling and shifting

    Full Text Available This article first explores individual memory as understood from the time of the ancient Greeks and Romans to modern-day neurology and psychology. The perspective is correlated with collective memory theory in the works of Halbwachs, Connerton, Gillis, Fentress and Wickham, Olick, Schwartz, Jan and Alida Assmann and Kirk and Thatcher. The relevance of ‘orality’ is highlighted in Kelber’s works, as well as in oral poetry performance by illiterate Yugoslavian bards, as discussed in studies by Parry, Lord and Havelock. Kelber’s challenge of Bultmann’s theory of oral tradition in the gospels is also covered. The article concludes with observations and reflections, opting for a position of moderate−to−strong constructionism.

  17. A Hierarchical Statistic Methodology for Advanced Memory System Evaluation

    Energy Technology Data Exchange (ETDEWEB)

    Sun, X.-J.; He, D.; Cameron, K.W.; Luo, Y.

    1999-04-12

    Advances in technology have resulted in a widening of the gap between computing speed and memory access time. Data access time has become increasingly important for computer system design. Various hierarchical memory architectures have been developed. The performance of these advanced memory systems, however, varies with applications and problem sizes. How to reach an optimal cost/performance design eludes researchers still. In this study, the authors introduce an evaluation methodology for advanced memory systems. This methodology is based on statistical factorial analysis and performance scalability analysis. It is two fold: it first determines the impact of memory systems and application programs toward overall performance; it also identifies the bottleneck in a memory hierarchy and provides cost/performance comparisons via scalability analysis. Different memory systems can be compared in terms of mean performance or scalability over a range of codes and problem sizes. Experimental testing has been performed extensively on the Department of Energy's Accelerated Strategic Computing Initiative (ASCI) machines and benchmarks available at the Los Alamos National Laboratory to validate this newly proposed methodology. Experimental and analytical results show this methodology is simple and effective. It is a practical tool for memory system evaluation and design. Its extension to general architectural evaluation and parallel computer systems are possible and should be further explored.

  18. Learning and memory

    P. A. J. Ryke

    1989-03-01

    Full Text Available Under various circumstances and in different species the outward expression of learning varies considerably, and this has led to the classification of different categories of learning. Just as there is no generally agreed on definition of learning, there is no one system of classification. Types of learning commonly recognized are: Habituation, sensitization, classical conditioning, operant conditioning, trial and error, taste aversion, latent learning, cultural learning, imprinting, insight learning, learning-set learning and instinct. The term memory must include at least two separate processes. It must involve, on the one hand, that of learning something and on the other, at some later date, recalling that thing. What lies between the learning and (he remembering must be some permanent record — a memory trace — within the brain. Memory exists in at least two forms: memory for very recent events (short-term which is relatively labile and easily disruptable; and long-term memory, which is much more stable. Not everything that gets into short-term memory becomes fixed in the long-term store; a filtering mechanism selects things that might be important and discards the rest.

    Compared with piezoelectric ceramics and magnetostrictive materials, the shape memory materials possess larger recoverable strain and recovery stress but slower response to external field. It is expected that the magneto-shape memory materials may develop considerable strain as well as rapid and precise shape control. Pseudoelasticity and shape memory effect (SME) resulted from martensitic transformation and its reverse transformation in shape memory materials were generally described. The requirements of appearing the shape memory effect in materials and the criteria for thermoelastic martensitic transformation were given. Some aspects concerning characteristics of martensitic transformation, and factors affecting SME in Ni-Ti, Cu-Zn-Al and Fe-Mn-Si based alloys as well as ZrO2 containing ceramics were briefly reviewed. Thermodynamic calculation of Ms temperature as function of grain size and parent ordering in Cu-Zn-Al was presented. The works on prediction of Ms in Fe-Mn-Si based alloys and in ZrO2-CeO2 were mentioned. Magnetic shape memory materials were briefly introduced.

    2016-08-01

    Evidence for innate immune memory (or 'priming') in invertebrates has been accumulating over the last years. We here provide an in-depth review of the current state of evidence for immune memory in invertebrates, and in particular take a phylogenetic viewpoint. Invertebrates are a very heterogeneous group of animals and accordingly, evidence for the phenomenon of immune memory as well as the hypothesized molecular underpinnings differ largely for the diverse invertebrate taxa. The majority of research currently focuses on Arthropods, while evidence from many other groups of invertebrates is fragmentary or even lacking. We here concentrate on immune memory that is induced by pathogenic challenges, but also extent our view to a non-pathogenic context, i.e. allograft rejection, which can also show forms of memory and can inform us about general principles of specific self-nonself recognition. We discuss definitions of immune memory and a number of relevant aspects such as the type of antigens used, the route of exposure, and the kinetics of reactions following priming.

    2010-01-01

    Medial temporal lobe epilepsy is a chronic neurological disease that begins in the early age and that is associated with frequent and disturbing memory deficits. Repeated seizures will lead to the formation of an epileptogenic network that may interfere with physiological neuronal networks and thus with normal brain function: by direct activation or indirectly by deactivation during a seizure, see for example the dreamy state or the ''déja vécu'' phenomenon during temporal seizures; by ictal or post-ictal inhibition, see for example ictal or post-ictal amnesia; by a repetitive and chronic modulation leading to a reorganization of the physiological neuronal networks. The study of these interactions between epileptic and physiological neural networks must lead to better explore the patient's memory and predict memory worsening before temporal lobe surgery and to better understand the reorganization of memory networks in chronic epilepsy. The goal is double: (1) improve the prediction of post-operative memory worsening and guide rehabilitation in epileptic clinical practice; (2) improve the pathophysiological knowledge about memory processes. © Société de Biologie, 2010.

  3. Music evokes vivid autobiographical memories.

    2016-08-01

    Music is strongly intertwined with memories-for example, hearing a song from the past can transport you back in time, triggering the sights, sounds, and feelings of a specific event. This association between music and vivid autobiographical memory is intuitively apparent, but the idea that music is intimately tied with memories, seemingly more so than other potent memory cues (e.g., familiar faces), has not been empirically tested. Here, we compared memories evoked by music to those evoked by famous faces, predicting that music-evoked autobiographical memories (MEAMs) would be more vivid. Participants listened to 30 songs, viewed 30 faces, and reported on memories that were evoked. Memories were transcribed and coded for vividness as in Levine, B., Svoboda, E., Hay, J. F., Winocur, G., & Moscovitch, M. [2002. Aging and autobiographical memory: Dissociating episodic from semantic retrieval. Psychology and Aging, 17, 677-689]. In support of our hypothesis, MEAMs were more vivid than autobiographical memories evoked by faces. MEAMs contained a greater proportion of internal details and a greater number of perceptual details, while face-evoked memories contained a greater number of external details. Additionally, we identified sex differences in memory vividness: for both stimulus categories, women retrieved more vivid memories than men. The results show that music not only effectively evokes autobiographical memories, but that these memories are more vivid than those evoked by famous faces.

  4. Verification of Embedded Memory Systems using Efficient Memory Modeling

    2011-01-01

    We describe verification techniques for embedded memory systems using efficient memory modeling (EMM), without explicitly modeling each memory bit. We extend our previously proposed approach of EMM in Bounded Model Checking (BMC) for a single read/write port single memory system, to more commonly occurring systems with multiple memories, having multiple read and write ports. More importantly, we augment such EMM to providing correctness proofs, in addition to finding real bugs as before. The novelties of our verification approach are in a) combining EMM with proof-based abstraction that preserves the correctness of a property up to a certain analysis depth of SAT-based BMC, and b) modeling arbitrary initial memory state precisely and thereby, providing inductive proofs using SAT-based BMC for embedded memory systems. Similar to the previous approach, we construct a verification model by eliminating memory arrays, but retaining the memory interface signals with their control logic and adding constraints on tho...

    A great deal of experimental investment is directed towards questions regarding the mechanisms of memory storage. Such studies have traditionally been restricted to investigation of the anatomical structures, physiological processes, and molecular pathways necessary for the capacity of memory storage, and have avoided the question of how individual memories are stored in the brain. Memory engram technology allows the labeling and subsequent manipulation of components of specific memory engrams in particular brain regions, and it has been established that cell ensembles labeled by this method are both sufficient and necessary for memory recall. Recent research has employed this technology to probe fundamental questions of memory consolidation, differentiating between mechanisms of memory retrieval from the true neurobiology of memory storage.

  6. Cholinesterase inhibitors and memory.

    Pepeu, Giancarlo; Giovannini, Maria Grazia

    2010-09-06

    A consensus exists that cholinesterase inhibitors (ChEIs) are efficacious for mild to moderate Alzheimer's Disease (AD). Unfortunately, the number of non-responders is large and the therapeutic effect is usually short-lasting. In experimental animals, ChEIs exert three main actions: inhibit cholinesterase (ChE), increase extracellular levels of brain acetylcholine (ACh), improve cognitive processes, particularly when disrupted in models of AD. In this overview we shall deal with the cognitive processes that are improved by ChEI treatment because they depend on the integrity of brain cholinergic pathways and their activation. The role of cholinergic system in cognition can be investigated using different approaches. Microdialysis experiments demonstrate the involvement of the cholinergic system in attention, working, spatial and explicit memory, information encoding, sensory-motor gating, skill learning. No involvement in long-term memory has yet been demonstrated. Conversely, memory consolidation is facilitated by low cholinergic activity. Experiments on healthy human subjects, notwithstanding caveats concerning age, dose, and different memory tests, confirm the findings of animal experiments and demonstrate that stimulation of the cholinergic system facilitates attention, stimulus detection, perceptual processing and information encoding. It is not clear whether information retrieval may be improved but memory consolidation is reduced by cholinergic activation. ChEI effects in AD patients have been extensively investigated using rating scales that assess cognitive and behavioural responses. Few attempts have been made to identify which scale items respond better to ChEIs and therefore, presumably, depend on the activity of the cholinergic system. Improvement in attention and executive functions, communication, expressive language and mood stability have been reported. Memory consolidation and retrieval may be impaired by high ACh levels. Therefore, considering

    Full Text Available Since Damasio introduced the somatic markers hypothesis in 1991, it has spread through the psychological community, where it is now commonly acknowledged that somatic states are a factor in producing the qualitative dimension of our experiences. Present actions are emotionally guided by those somatic states that were previously activated in similar experiences. In this model, somatic markers serve as a kind of embodied memory.Here we test whether the manipulation of somatic markers can modulate the emotional evaluation of negative memories. Because facial feedback has been shown to be a powerful means of modifying emotional judgements, we used it to manipulate somatic markers. Participants first read a sad story in order to induce a negative emotional memory and then were asked to rate their emotions and memory about the text. Twenty-four hours later, the same participants were asked to assume a predetermined facial feedback (smiling while reactivating their memory of the sad story. The participants were once again asked to fill in emotional and memory questionnaires about the text. Our results showed that participants who had smiled during memory reactivation later rated the text less negatively than control participants. However, the contraction of the zygomaticus muscles during memory reactivation did not have any impact on episodic memory scores. This suggests that manipulating somatic states modified emotional memory without affecting episodic memory. Thus, modulating memories through bodily states might pave the way to studying memory as an embodied function and help shape new kinds of psychotherapeutic interventions.

It includes acquiring information (perception,selecting (attention, representing (understanding and retaining (memory information and using it to guidebehavior (reasoning and coordination of motor outputs.There are so many conditions associated with memory and cognitive impairment which include Aging,Alzheimer’s disease, Stroke, Stress, Head injuries, Seizures, Benzodiazepines, Brain tumors, Depression, Temporallobe defects and Schizophrenia etc.Choline rich foods can enhance memory and learning and may be useful in improving cognitive abilities. Theseinclude sea foods, liver, egg yolk, soysbeans, broccoli, ash gourd. Coloured fruits and vegetables are good source ofantioxidants which improve concentration. It is advised to decrease the consumption of foods rich in transfats likehydrogenated oils, fried foods, beef, pork, mutton and ice creams and pastries. Such foods increase the deposition offats in the neurons and impair cognition. Tea, cocoa and turmeric are reported to have good nootropic activity i.e.improving memory and learning. Apart from the foods, one should keep the brain active to maintain its cognitivefunction well.

    Copper-based shape memory alloys (SMAs) exhibit excellent shape memory properties in single crystalline form. However, when they are polycrystalline, their shape memory properties are severely compromised by brittle fracture arising from transformation strain incompatibility at grain boundaries and triple junctions. Oligocrystalline shape memory alloys (oSMAs) are microstructurally designed SMA structures in which the total surface area exceeds the total grain boundary area, and triple junctions can even be completely absent. Here it is shown how an oligocrystalline structure provides a means of achieving single crystal-like SMA properties without being limited by constraints of single crystal processing. Additionally, the formation of oSMAs typically involves the reduction of the size scale of specimens, and sample size effects begin to emerge. Recent findings on a size effect on the martensitic transformation in oSMAs are compared and a new regime of heat transfer associated with the transformation heat evolution in these alloys is discussed. New results on unassisted two-way shape memory and the effect of loading rate in oSMAs are also reported. (Copyright copyright 2012 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim)

    2007-09-01

    Full Text Available A fundamental problem in neuroscience is understanding how working memory--the ability to store information at intermediate timescales, like tens of seconds--is implemented in realistic neuronal networks. The most likely candidate mechanism is the attractor network, and a great deal of effort has gone toward investigating it theoretically. Yet, despite almost a quarter century of intense work, attractor networks are not fully understood. In particular, there are still two unanswered questions. First, how is it that attractor networks exhibit irregular firing, as is observed experimentally during working memory tasks? And second, how many memories can be stored under biologically realistic conditions? Here we answer both questions by studying an attractor neural network in which inhibition and excitation balance each other. Using mean-field analysis, we derive a three-variable description of attractor networks. From this description it follows that irregular firing can exist only if the number of neurons involved in a memory is large. The same mean-field analysis also shows that the number of memories that can be stored in a network scales with the number of excitatory connections, a result that has been suggested for simple models but never shown for realistic ones. Both of these predictions are verified using simulations with large networks of spiking neurons.

Through the control of the stochastic filament formation at low voltage, the NP SiOx memory exhibited an extremely low electroforming voltage (∼ 1.6 V) and outstanding performance metrics. These include multibit storage ability (up to 9-bits), a high ON-OFF ratio (up to 10(7) A), a long high-temperature lifetime (≥ 10(4) s at 100 °C), excellent cycling endurance (≥ 10(5)), sub-50 ns switching speeds, and low power consumption (∼ 6 × 10(-5) W/bit). Also provided is the room temperature processability for versatile fabrication without any compliance current being needed during electroforming or switching operations. Taken together, these metrics in NP SiOx RRAM provide a route toward easily accessed nonvolatile memory applications.

  16. Prosthetic memory and post-memory: cultural encounters with the past in designing a museum

    Full Text Available This paper1 investigates the sources of representations on the communist period and the type of engagement with the past in an experiential museum, in the context of the National Network of Romanian Museums’ project for a laboratory-museum of Romanian Communism. Our analysis of focus-groups in October-November 2012 explores the public’s expectations in terms of museum experience and engagement with objects and the potential of an experiential museum to facilitate deliberation about the past. We use the conceptual framework of recent studies on postmemory (Hirsch, 2008 and prosthetic memory (Landsberg, 2004, 2009 to focus on ways of building the experiential archive needed to produce prosthetic memory. We consider that such an analysis is relevant for two interconnected problems: the bidirectional relationship between a projected museum of communism and a prospective public, and the methodological insights available for investigating this relation. With regard to the first problem, this paper makes a case for treating museums as a memory device rather than a lieu de memoire and analyses the role of the museum in relation to cultural memory. With regard to the second problem, it offers an example of conducting research on prospective publics which departs from traditional marketing approaches, adopting theoretical insights and analytical categories from specific conceptualizations in the field of memory studies.

    Since the end of the last century," Walter Benjamin wrote, "philosophy has made a series of attempts to lay hold of the 'true' experience as opposed to the kind that manifests itself in the standardized, denatured life of the civilized masses. It is customary to classify these efforts under the heading of a philosophy of life. Towering above this literature is Henri Bergson's early monumental work, Matter and Memory."Along with Husserl's Ideas and Heidegger's Being and Time, Bergson's work represents one of the great twentieth-century investigations into perception and memory, movement and time, matter and mind. Arguably Bergson's most significant book, Matter and Memory is essential to an understanding of his philosophy and its legacy.This new edition includes an annotated bibliography prepared by Bruno Paradis.Henri Bergson (1859-1941) was awarded the Nobel Prize in 1927. His works include Time and Free Will, An Introduction to Metaphysics, Creative Evolution, and The Creative Mind.

  1. Emotion and autobiographical memory

    Science.gov (United States)

    Holland, Alisha C.; Kensinger, Elizabeth A.

    2010-03-01

    Autobiographical memory encompasses our recollections of specific, personal events. In this article, we review the interactions between emotion and autobiographical memory, focusing on two broad ways in which these interactions occur. First, the emotional content of an experience can influence the way in which the event is remembered. Second, emotions and emotional goals experienced at the time of autobiographical retrieval can influence the information recalled. We discuss the behavioral manifestations of each of these types of interactions and describe the neural mechanisms that may support those interactions. We discuss how findings from the clinical literature (e.g., regarding depression) and the social psychology literature (e.g., on emotion regulation) might inform future investigations of the interplay between the emotions experienced at the time of retrieval and the memories recalled, and we present ideas for future research in this domain.

    This volume consists of a selection of the Albert Einstein Memorial Lectures presented annually at the Israel Academy of Sciences and Humanities. Delivered by eminent scientists and scholars, including Nobel laureates, they cover a broad spectrum of subjects in physics, chemistry, life science, mathematics, historiography and social issues. This distinguished memorial lecture series was inaugurated by the Israel Academy of Sciences and Humanities following an international symposium held in Jerusalem in March 1979 to commemorate the centenary of Albert Einstein's birth. Considering that Einstein's interests, activities and influence were not restricted to theoretical physics but spanned broad fields affecting society and the welfare of humankind, it was felt that these memorial lectures should be addressed to scientists, scholars and erudite laypersons rather than to physicists alone.

    2011-01-01

    Many data structures support dictionaries, also known as maps or associative arrays, which store and manage a set of key-value pairs. A \\emph{multimap} is generalization that allows multiple values to be associated with the same key. For example, the inverted file data structure that is used prevalently in the infrastructure supporting search engines is a type of multimap, where words are used as keys and document pointers are used as values. We study the multimap abstract data type and how it can be implemented efficiently online in external memory frameworks, with constant expected I/O performance. The key technique used to achieve our results is a combination of cuckoo hashing using buckets that hold multiple items with a multiqueue implementation to cope with varying numbers of values per key. Our external-memory results are for the standard two-level memory model.

    2013-01-01

    It is a paradigm to capture the spread of information and disease with random flow on networks. However, this conventional approach ignores an important feature of the dynamics: where flow moves to depends on where it comes from. That is, memory matters. We analyze multi-step pathways from different systems and show that ignoring memory has profound consequences for community detection and ranking as well as for epidemic spreading. Specifically, memoryless dynamics on networks understate the effect of communities and exaggerate the effect of highly connected nodes. Including memory reveals actual travel patterns in air traffic, ranking that favors specialized journals in scientific communication, and diseases that spread more slowly and persist longer in hospitals.

  8. Shape-memory polymers

    Directory of Open Access Journals (Sweden)

    Marc Behl

    2007-04-01

    Full Text Available Shape-memory polymers are an emerging class of active polymers that have dual-shape capability. They can change their shape in a predefined way from shape A to shape B when exposed to an appropriate stimulus. While shape B is given by the initial processing step, shape A is determined by applying a process called programming. We review fundamental aspects of the molecular design of suitable polymer architectures, tailored programming and recovery processes, and the quantification of the shape-memory effect. Shape-memory research was initially founded on the thermally induced dual-shape effect. This concept has been extended to other stimuli by either indirect thermal actuation or direct actuation by addressing stimuli-sensitive groups on the molecular level. Finally, polymers are introduced that can be multifunctional. Besides their dual-shape capability, these active materials are biofunctional or biodegradable. Potential applications for such materials as active medical devices are highlighted.

    Recent advances in shape memory polymer (SMP) foam research are reviewed. The SMPs belong to a new class of smart polymers which can have interesting applications in microelectromechanical systems, actuators and biomedical devices. They can respond to specific external stimulus changing their configuration and then remember the original shape. In the form of foams, the shape memory behaviour can be enhanced because they generally have higher compressibility. Considering also the low weight, and recovery force, the SMP foams are expected to have great potential applications primarily in aerospace. This review highlights the recent progress in characterization, evaluation, and proposed applications of SMP foams mainly for aerospace applications.

    Natural killer (NK) cells have historically been considered short-lived cytolytic cells that can rapidly respond against pathogens and tumors in an antigen-independent manner and then undergo cell death. Recently, however, NK cells have been shown to possess traits of adaptive immunity and can acquire immunological memory in a manner similar to that of T and B cells. In this review, we discuss evidence of NK cell memory and the mechanisms involved in the generation and survival of these innate lymphocytes. Copyright © 2015 Elsevier Inc. All rights reserved.

  20. Pleasantness bias in flashbulb memories: positive and negative flashbulb memories of the fall of the Berlin Wall among East and West Germans.

    Science.gov (United States)

    Bohn, Annette; Berntsen, Dornhe

    2007-04-01

    Flashbulb memories for the fall of the Berlin Wall were examined among 103 East and West Germans who considered the event as either highly positive or highly negative. The participants in the positive group rated their memories higher on measures of reliving and sensory imagery, whereas their memory for facts was less accurate than that of the participants in the negative group. The participants in the negative group had higher ratings on amount of consequences but had talked less about the event and considered it less central to their personal and national identity than did the participants in the positive group. In both groups, rehearsal and the centrality of the memory to the person's identity and life story correlated positively with memory qualities. The results suggest that positive and negative emotions have different effects on the processing and long-term retention of flashbulb memories.

  3. Neuroepigenetic regulation of pathogenic memories

    Directory of Open Access Journals (Sweden)

    Stephanie E. Sillivan

    2015-01-01

    Full Text Available Our unique collection of memories determines our individuality and shapes our future interactions with the world. Remarkable advances into the neurobiological basis of memory have identified key epigenetic mechanisms that support the stability of memory. Various forms of epigenetic regulation at the levels of DNA methylation, histone modification, and noncoding RNAs can modulate transcriptional and translational events required for memory processes. By changing the cellular profile in the brain’s emotional, reward, and memory circuits, these epigenetic modifications have also been linked to perseverant, pathogenic memories. In this review, we will delve into the relevance of epigenetic dysregulation to pathogenic memory mechanisms by focusing on 2 neuropsychiatric disorders perpetuated by aberrant memory associations: substance use disorder and post-traumatic stress disorder. As our understanding improves, neuroepigenetic mechanisms may someday be harnessed to develop novel therapeutic targets for the treatment of these chronic, relapsing disorders.

  4. Emotional organization of autobiographical memory.

    Science.gov (United States)

    Schulkind, Matthew D; Woldorf, Gillian M

    2005-09-01

    The emotional organization of autobiographical memory was examined by determining whether emotional cues would influence autobiographical retrieval in younger and older adults. Unfamiliar musical cues that represented orthogonal combinations of positive and negative valence and high and low arousal were used. Whereas cue valence influenced the valence of the retrieved memories, cue arousal did not affect arousal ratings. However, high-arousal cues were associated with reduced response latencies. A significant bias to report positive memories was observed, especially for the older adults, but neither the distribution of memories across the life span nor response latencies varied across memories differing in valence or arousal. These data indicate that emotional information can serve as effective cues for autobiographical memories and that autobiographical memories are organized in terms of emotional valence but not emotional arousal. Thus, current theories of autobiographical memory must be expanded to include emotional valence as a primary dimension of organization.

  8. About sleep's role in memory.

    Science.gov (United States)

    Rasch, Björn; Born, Jan

    2013-04-01

    Over more than a century of research has established the fact that sleep benefits the retention of memory. In this review we aim to comprehensively cover the field of "sleep and memory" research by providing a historical perspective on concepts and a discussion of more recent key findings. Whereas initial theories posed a passive role for sleep enhancing memories by protecting them from interfering stimuli, current theories highlight an active role for sleep in which memories undergo a process of system consolidation during sleep. Whereas older research concentrated on the role of rapid-eye-movement (REM) sleep, recent work has revealed the importance of slow-wave sleep (SWS) for memory consolidation and also enlightened some of the underlying electrophysiological, neurochemical, and genetic mechanisms, as well as developmental aspects in these processes. Specifically, newer findings characterize sleep as a brain state optimizing memory consolidation, in opposition to the waking brain being optimized for encoding of memories. Consolidation originates from reactivation of recently encoded neuronal memory representations, which occur during SWS and transform respective representations for integration into long-term memory. Ensuing REM sleep may stabilize transformed memories. While elaborated with respect to hippocampus-dependent memories, the concept of an active redistribution of memory representations from networks serving as temporary store into long-term stores might hold also for non-hippocampus-dependent memory, and even for nonneuronal, i.e., immunological memories, giving rise to the idea that the offline consolidation of memory during sleep represents a principle of long-term memory formation established in quite different physiological systems.

    This instrumentation grant funded the development and installation of a state-of-the-art laser system to be used for the DOE funded research at the J.R. Macdonald Laboratory at Kansas State University. Specifically, we purchased a laser based on the KMLABs Red-Dragon design, which has a high repetition rate of 10-20 kHz crucial for multi-parameter coincidence measurements conducted in our lab. This laser system is carrier-envelope phase (CEP) locked and provides pulses as short as 21 fs directly from the amplifier (see details below). In addition, we have developed a pulse compression setup that provides sub 5 fs pulses and a CEP tagging capability that allows for long measurements of CEP dependent processes.

    The setting for this case study is the Dolph Briscoe, Jr. Library, University of Texas Health Science Center at San Antonio, a health sciences campus with medical, dental, nursing, health professions, and graduate schools. During 2008-2009, major renovations to the library building were completed including office space for a faculty development department, multipurpose classrooms, a 24/7 study area, study rooms, library staff office space, and an information commons. The impetus for changes to the library building was the decreasing need to house collections in an increasingly electronic environment, the need for office space for other departments, and growth of the student body. About 40% of the library building was remodeled or repurposed, with a loss of approximately 25% of the library's original space. Campus administration proposed changes to the library building, and librarians worked with administration, architects, and construction managers to seek renovation solutions that meshed with the library's educational mission.

    DEFF Research Database (Denmark)

    Ravn, Susanne

    In the analysis of body-memory and improvisation presented in this paper I contend that dancers’ specialised body-memory are not to be understood as more or less automatized. Rather, in each repetition, body-memories – or habits – are to be understood as unfolding in response to the actual contex...

    Stress effects on memory are well-known. Most studies, however, focused on the impact of stress on hippocampus-dependent 'declarative' memory processes. Less is known about whether stress influences also striatum-based memory processes, such as stimulus-response (S-R) memory. First evidence from rodent experiments shows that glucocorticoid stress hormones may enhance the consolidation of S-R memories. Whether stress affects also S-R memory retrieval remains largely elusive. Therefore, we tested in the present experiment in humans the effect of stress on the retrieval of S-R memories. Healthy men and women were trained to locate three objects in an S-R version of a virtual eight-arm radial maze. One week later, participants underwent a stressor or a control condition before their memory of the S-R task was tested. Our results showed that participants (n=43) who were exposed to the stressor before retention testing made significantly more errors in this test trial, suggesting that stress impaired S-R memory retrieval. Moreover, high cortisol concentrations were associated with reduced S-R memory. These findings indicate that stress may affect memory retrieval processes in humans beyond hippocampal 'declarative' memory.
