  1. LHC Olympics: Advanced Analysis Techniques

    NASA Astrophysics Data System (ADS)

    Armour, Kyle; Larkoski, Andrew; Gray, Amanda; Ventura, Dan; Walsh, Jon; Schabinger, Rob

    2006-05-01

    The LHC Olympics is a series of workshop aimed at encouraging theorists and experimentalists to prepare for the soon-to-be-online Large Hadron Collider in Geneva, Switzerland. One aspect of the LHC Olympics program consists of the study of simulated data sets which represent various possible new physics signals as they would be seen in LHC detectors. Through this exercise, LHC Olympians learn the phenomenology of possible new physics models and gain experience in analyzing LHC data. Additionally, the LHC Olympics encourages discussion between theorists and experimentalists, and through this collaboration new techniques could be developed. The University of Washington LHC Olympics group consists of several first-year graduate and senior undergraduate students, in both theoretical and experimental particle physics. Presented here is a discussion of some of the more advanced techniques used and the recent results of one such LHC Olympics study.

  4. Flex-Gears

    NASA Technical Reports Server (NTRS)

    Tsai, Lung-Wen; Peritt, Jonathan

    1993-01-01

    Flex-Gears are being developed as an alternative to brushes and slip rings to conduct electricity across a rotating joint. Flex-Gears roll in the annulus of sun and ring gears for electrical contact while maintaining their position by using a novel application of involute gears. A single Flex-Gear is predicted to transfer up to 2.8 amps, thereby allowing a six inch diameter device, holding 30 Flex-Gears, to transfer over 80 amps. Semi-rigid Flex-Gears are proposed to decrease Flex-Gear stress and insure proper gear meshing.

  5. Flex: RSRE's capability computer

    NASA Astrophysics Data System (ADS)

    Foster, J. M.

    The Flex capability based computer architecture is described. It supports a multilanguage environment, and compilers for ALGOL 168 and PASCAL exist; an Ada compiler is being completed. The idea of capabilities is used on backing store as well as main store, so that all kinds of structured object which can be held in main store can also be held on any of the packing stores with the same degree of protection. Capabilities are used across a network of Flex computers, so that capabilities for data in one machine may be passed to and held in another. Flex uses true procedure values in the sense of Landin (1964).

  7. Pressure vessel flex joint

    NASA Technical Reports Server (NTRS)

    Kahn, Jon B. (Inventor)

    1992-01-01

    An airtight, flexible joint is disclosed for the interfacing of two pressure vessels such as between the Space Station docking tunnel and the Space Shuttle Orbiter bulkhead adapter. The joint provides for flexibility while still retaining a structural link between the two vessels required due to the loading created by the internal/external pressure differential. The joint design provides for limiting the axial load carried across the joint to a specific value, a function returned in the Orbiter/Station tunnel interface. The flex joint comprises a floating structural segment which is permanently attached to one of the pressure vessels through the use of an inflatable seal. The geometric configuration of the joint causes the tension between the vessels created by the internal gas pressure to compress the inflatable seal. The inflation pressure of the seal is kept at a value above the internal/external pressure differential of the vessels in order to maintain a controlled distance between the floating segment and pressure vessel. The inflatable seal consists of either a hollow torus-shaped flexible bladder or two rolling convoluted diaphragm seals which may be reinforced by a system of straps or fabric anchored to the hard structures. The joint acts as a flexible link to allow both angular motion and lateral displacement while it still contains the internal pressure and holds the axial tension between the vessels.

  8. Resistive flex sensors: a survey

    NASA Astrophysics Data System (ADS)

    Saggio, Giovanni; Riillo, Francesco; Sbernini, Laura; Quitadamo, Lucia Rita

    2016-01-01

    Resistive flex sensors can be used to measure bending or flexing with relatively little effort and a relatively low budget. Their lightness, compactness, robustness, measurement effectiveness and low power consumption make these sensors useful for manifold applications in diverse fields. Here, we provide a comprehensive survey of resistive flex sensors, taking into account their working principles, manufacturing aspects, electrical characteristics and equivalent models, useful front-end conditioning circuitry, and physic-bio-chemical aspects. Particular effort is devoted to reporting on and analyzing several applications of resistive flex sensors, related to the measurement of body position and motion, and to the implementation of artificial devices. In relation to the human body, we consider the utilization of resistive flex sensors for the measurement of physical activity and for the development of interaction/interface devices driven by human gestures. Concerning artificial devices, we deal with applications related to the automotive field, robots, orthosis and prosthesis, musical instruments and measuring tools. The presented literature is collected from different sources, including bibliographic databases, company press releases, patents, master’s theses and PhD theses.

    Clapper, M. L.

    1993-01-01

    This volume, Volume 2, of this Flex Bearing UUEC Final Report documents findings and data pertaining to Team B's tasks. Team B was organized as one of two sub-teams of the Unplanned/Unintended Event or Condition (UUEC) board established per InterOffice Memorandum (IOM) A100-FY93-072. Team A determined the cause of the unacceptable unbonds (referred to as 'heat-affect' unbonds), including the initial, light rust film, in the FSM #3 flex bearing was overheating of the Forward End Ring (FER) during cure, specifically in zone 8 of the mold. Team A's findings are documented in Volume 1 of this report. Team B developed flight rationale for existing bearings, based on absence or presence of an unpropitious unbond condition like that in FSM #3's flex bearing.

  18. Spatial heterodyne spectrometer for FLEX

    NASA Astrophysics Data System (ADS)

    Scott, Alan; Zheng, Sheng-Hai; Brown, Stephen; Bell, Andrew

    2007-10-01

    A spatial heterodyne spectrometer (SHS) has significant advantages for high spectral resolution imaging over narrow pre-selected bands compared to traditional solutions. Given comparable optical étendue at R~6500, a field-widened SHS will have a throughput-resolution product ~170 x larger than an air-spaced etalon spectrometer, and ~1000 x larger than a standard grating spectrometer. The monolithic glass Michelson design and lack of moving parts allows maximum stability of spectral calibration over the mission life. For these reasons, SHS offers considerable advantages for the core spectrometer instrument in the European Space Agency's (ESA) Fluorescence Explorer (FLEX) mission.

  19. AcroFlex design and results.

    PubMed

    Fraser, Robert D; Ross, E Raymond; Lowery, Gary L; Freeman, Brian J; Dolan, Mark

    2004-01-01

    The AcroFlex prosthesis is unique when compared to other current devices, as it has an elastomeric core sandwiched between two titanium endplates. The purpose of this design was to optimize shock absorption qualities. This paper reviews the design of the AcroFlex Disc and relevant design and outcomes of two pilot studies carried out on 28 patients using the AcroFlex prosthesis. Although clinical outcomes of the pilot studies were successful, the pivotal randomized trial has not been carried out due to detection of mechanical failure of the elastomer on thin cut CT scans. The implications of this for the AcroFlex and other arthroplasties are discussed.

    Lang, M.; Fischer, J.; Werner, M.; Sommer, J.-U.

    2014-06-01

    The swelling equilibrium of Olympic gels, which are composed of entangled cyclic polymers, is studied by Monte Carlo simulations. In contrast to chemically cross-linked polymer networks, we observe that Olympic gels made of chains with a larger degree of polymerization, N, exhibit a smaller equilibrium swelling degree, Q∝N-0.28ϕ0-0.72, at the same polymer volume fraction ϕ0 at network preparation. This observation is explained by a desinterspersion (reorganization with release of nontrapped entanglements) process of overlapping nonconcatenated rings upon swelling.

Similar spirit and endeavour can be found throughout the microbial world, in which every day is a competition to survive and thrive. Microorganisms are trained through evolution to become the fittest and the best adapted to a particular environmental niche or lifestyle, and to innovate when the ‘rules of the game’ are changed by alterations to their natural habitats. In this Essay, we honour the best competitors in the microbial world by inviting them to take part in the inaugural Microbial Olympics. PMID:22796885

  16. Improved FlexX docking using FlexS-determined base fragment placement.

    PubMed

    Cross, Simon S J

    2005-01-01

    We report on a novel hybrid FlexX/FlexS docking approach, whereby the base fragment of the test ligand is chosen by FlexS superposition onto a cocrystallized template ligand and then fed into FlexX for the incremental construction of the final solution. The new approach is tested on the diverse 200 protein-ligand complex dataset that has been previously described for FlexX validation. In total, 62.9% of the complexes can be reproduced at rank 1 by our approach, which compares favorably with 46.9% when using FlexX alone. In addition, we report "cross-docking" experiments in which several receptor structures of complexes with identical proteins have been used for docking all cocrystallized ligands of these complexes. The results show that, in almost all cases, the hybrid approach can acceptably dock a ligand into a foreign receptor structure using a different ligand template, can give solutions where FlexX alone fails, and tends to give solutions that are more accurately positioned.

    Vranish, John; Peritt, Jonathan

    1993-01-01

    This study was conducted to develop an alternative way of transferring electricity across a continuously rotating joint, with little wear and the potential for low electrical noise. The problems with wires, slip rings, electromagnetic couplings, and recently invented roll-rings are discussed. Flex-gears, an improvement of roll-rings, are described. An entire class of flexgear devices is developed. Finally, the preferred flex-gear device is optimized for maximum electrical contact and analyzed for average mechanical power loss and maximum stress. For a device diameter of six inches, the preferred device is predicted to have a total electrical contact area of 0.066 square inches. In the preferred device, a small amount of internal sliding produces a 0.003 inch-pound torque that resists the motion of the device.

But, in 25 per cent of other events (1) cycling, (2) fencing, (3) gymnastics, (4) judo, (5) weightlifting and (6) Graeco Roman wrestling the U.S.A. did not win a single medal. The failure of the U.S.A. to maintain her lead in Munich was largely due to weaknesses in these other events in many of which the potential medallists can be derived from the lower half of the height distribution (events 3 to 6). These weaknesses are Russia's strength and they continued to remain unstrengthened at Montreal. Also, the domination held by the U.S.A. in swimming was seriously challenged by East Germany. The present trends indicate that the U.S.A.'s ranking is likely to slip further to the third position in Moscow 1980. Factors inhibiting the survival of the Olympics are pointed.

  14. Olympic sports and transsexuals.

    PubMed

    Gooren, Louis J

    2008-05-01

    Sex segregation in competitive sports is regarded as fair. Before puberty boys and girls do not differ in height, muscle and bone mass. Testosterone (T) exposure during puberty leads to an ultimate average greater height in men of 12-15 cm, longer and larger bones and muscle mass and strength and higher hemoglobin levels. Postpubertal androgen ablation reverses, at least in part, previous anabolic effects of T on muscle, bone mineral density and hemoglobin but the long bones remain longer and wider. T administration dose dependently increases muscle mass and maximal voluntary strength. Therefore, exogenous androgens, being performance enhancing drugs, are banned for all athletes. An issue is the participation in competitive sports of people with errors of sexual differentiation and particularly transsexuals who have been sex-reassigned. In view of the effects of T, a clear demarcation is whether sex reassignment has taken place before or after hormonal puberty. Pubertal effects of T are in part reversible but there is no reliable evidence as to its completeness. The International Olympic Committee (IOC) has taken an inevitably arbitrary decision with regard to participation of sex-reassigned transsexuals in elite sports: sex reassignment must have taken place at least two years earlier, hormone treatment must be appropriate for the reassigned sex and the reassigned sex must be legally recognized. The IOC policy is not binding for other organizations.

  15. Deployment of FlexCHP System

    The Gas Technology Institute (GTI), along with its partner Integrated CHP Systems Corporation, has developed and demonstrated an Ultra-Low-Nitrogen Oxide (ULN) Flexible Combined Heat and Power (FlexCHP) system that packages a state-of-the-art Capstone C65 gas microturbine and Johnston PFXX100 boiler with an innovative natural gas-fired supplemental burner. Supplemental burners add heat as needed in response to facility demand, which increases energy efficiency, but typically raises exhaust NOx levels, degrading local air quality unless a costly and complicated catalytic treatment system is added. The FlexCHP system increases energy efficiency and achieves the 2007 California Air Resource Board (CARB) distributed generation emissions standards for Nitrogen oxides (NOx), Carbon Monoxide (CO), and Total Hydrocarbons (THC) without catalytic exhaust gas treatment. The key to this breakthrough performance is a simple and reliable burner design which utilizes staged combustion with engineered internal recirculation. This ULN burner system successfully uses turbine exhaust as an oxidizer, while achieving high efficiencies and low emissions. In tests at its laboratory facilities in Des Plaines, Illinois, GTI validated the ability of the system to achieve emissions of NOx, CO, and THC below the CARB criteria of 0.07, 0.10, and 0.02 lb/MW-h respectively. The FlexCHP system was installed at the field demonstration site, Inland Empire Foods, in Riverside, California to verify performance of the technology in an applied environment. The resulting Combined Heat and Power (CHP) package promises to make CHP implementation more attractive, mitigate greenhouse gas emissions, and improve the reliability of electricity supply.

  20. FlexSnap: Flexible Non-sequential Protein Structure Alignment

    NASA Astrophysics Data System (ADS)

    Salem, Saeed; Zaki, Mohammed J.; Bystroff, Chris

    Proteins have evolved subject to energetic selection pressure for stability and flexibility. Structural similarity between proteins which have gone through conformational changes can be captured effectively if flexibility is considered. Topologically unrelated proteins that preserve secondary structure packing interactions can be detected if both flexibility and sequence permutations are considered. We propose the FlexSnap algorithm for flexible non-topological protein structural alignment. The effectiveness of FlexSnap is demonstrated by measuring the agreement of its alignments with manually curated non-sequential structural alignments. FlexSnap showed competitive results against state-of-the-art algorithms, like DALI, SARF2, MultiProt, FlexProt, and FATCAT.

  2. Physiological assessment of Olympic windsurfers.

    PubMed

    Vogiatzis, Ioannis; De Vito, Giuseppe

    2015-01-01

    Olympic boardsailing is a very demanding endurance sport activity. The main reason for this phenomenon is ascribable to the fact that elite windsurfers use pumping for propulsion during sailing. Pumping is a manoeuvre in which the athlete pulls the sail rhythmically so that it acts as a wing, thus providing the board with additional forward motion especially in light and moderate wind conditions. It has been demonstrated, by using portable metabolimeters, that Olympic boardsailing (Mistral board and the current Olympic board the Neil Pryde RS:X) entails high energy and cardiorespiratory requirements. In elite Olympic board-sailors, by measuring energy costs and cardiorespiratory responses, it was found that (in wind velocity conditions ranging between 4 and 15 m s(-1)) pumping, compared to non-pumping sailing, induced a significant increase in oxygen uptake (VO₂) and heart rate (HR) demands (from 19.2 to 48.4 ml min(-1) kg(-1) and from 110 to 165 beats min(-1), respectively). In general, across studies the aerobic demand, recorded on various windsurf boards (expressed as% VO₂max), was greater than 75%, whilst HR values were greater than 85% of HRmax during actual racing conditions. In conclusion, Olympic class windsurfing can be considered as a high-intensity endurance type of sport that is comparable to other aerobic sporting activities such as rowing. Sail pumping is the crucial factor determining this high intensity of aerobic demand. Moreover, the fact that a typical regatta includes many races over several days implies that particular attention must be paid to the training strategy and the nutritional requirement of this discipline.

  3. Eclipses and the Olympics

    2000-12-01

    Like returns of Halley's comet the Olympic games occur periodically, though not as regularly in antiquity. Dates were also imprecise due to the chaotic calendars in use. Reported sightings of comets and eclipses can be used with game dates to help fix ancient events. However some reported darkening of the sun, e.g., after Julius Caesar's murder in 44 BC, was due to volcanic eruptions. A red comet, visible in daylight, first appeared during the games that year. It was also seen from China and Korea (Pang, Sciences 31, 30). Phlegon's ``Olympiads" (2nd century) says that Christ's crucifixion was in the 4th year of the 202nd Olympiad (AD 29-33), when a total solar eclipse occurred in the 6th hour. Only the Nov. 24, AD 29 eclipse over Asia Minor can match that, and Joel's prophecy (Acts 2, 14-21) that ``the sun will be turned to darkness and moon to blood." However it conflicts with ``the first day of Passover," as recorded by Mathew, Mark and Luke, i.e., full moon in early spring. Humphreys and Waddington (Nature 306, 743) have suggested meteorological darkening and the April 3, AD 33 lunar eclipse instead. Schaefer has questioned the eclipse's visibility from Jerusalem (31.46N, 35.14E). The six computations he cited gave dissimilar answers due to the imprecise rates of the secular lunar acceleration, and lengthening of the day used (Q.Jl.R.astr.Soc. 31, 53). Lunar laser ranging has since fixed the former at -26"/cen2. Analysis of ancient Chinese solar eclipse records, e.g., the April 21, 899 BC and April 4, AD 368 ``double dawns" over Zheng, has given us a delta T (in sec) = 30t2, where t is centuries before 1800 (Pang, Yau and Chou, in ``Dynamics of Ice Age Earth: A Modern Perspective," 1998). Our computations show that the moon rose over Jerusalem, with 1/3 still in the umbra and the rest in penumbra. Holdover meteorological darkening with long absorption air mass could have help reddened the moon also. Finally the first ``eclipse season" (the Aug. 21 lunar, and

  17. Flex fuel polygeneration: Integrating renewable natural gas

    NASA Astrophysics Data System (ADS)

    Kieffer, Matthew

    Flex Fuel Polygeneration (FFPG) is the use of multiple primary energy sources for the production of multiple energy carriers to achieve increased market opportunities. FFPG allows for adjustments in energy supply to meet market fluctuations and increase resiliency to contingencies such as weather disruptions, technological changes, and variations in supply of energy resources. In this study a FFPG plant is examined that uses a combination of the primary energy sources natural gas and renewable natural gas (RNG) derived from MSW and livestock manure and converts them into energy carriers of electricity and fuels through anaerobic digestion (AD), Fischer-Tropsch synthesis (FTS), and gas turbine cycles. Previous techno-economic analyses of conventional energy production plants are combined to obtain equipment and operating costs, and then the 20-year NPVs of the FFPG plant designs are evaluated by static and stochastic simulations. The effects of changing operating parameters are investigated, as well as the number of anaerobic digestion plants on the 20-year NPV of the FTS and FFPG systems.

    To compare the phase transformation behaviour, the microstructure, the nano-hardness and the surface chemistry of electro-discharge machined HyFlex EDM instruments with conventionally manufactured HyFlex CM. New and laboratory used HyFlex EDM were examined by X-ray diffraction (XRD) and differential scanning calorimetry (DSC). Nano-hardness and modulus of elasticity were also investigated using a maximum load of 20 mN with a minimum of 40 significant indentations for each sample. Raman spectroscopy and field emission-scanning electron microscope (FE-SEM) were used to assess the surface chemistry of HyFlex EDM. HyFlex CM were subjected to the same investigations and used as a comparison. Nano-indentation data were statistically analysed using the Student's t-test. XRD analysis on HyFlex EDM revealed the presence of martensite and rhombohedral R-phase, while a mixture of martensite and austenite structure was identified in HyFlex CM. DSC analysis also disclosed higher austenite finish (Af) temperatures for electro-discharge machining (EDM) instruments. Significant differences in nano-hardness and modulus of elasticity were found between EDM and CM files (P < 0.05). FE-SEM and EDS analyses confirmed that both new EDM and CM files were covered by an oxide layer. Micro-Raman spectroscopy assessed the presence of rutile-TiO2 . HyFlex EDM revealed peculiar structural properties, such as increased phase transformation temperatures and hardness. Present results corroborated previous findings and shed light on the enhanced mechanical behaviour of these instruments. © 2016 International Endodontic Journal. Published by John Wiley & Sons Ltd.

    Amphibians evolved from fishes about 360 million years ago and were the first vertebrates adapted to life on land. The word amphibian means "double life." It refers to the life history of many amphibians, which spend part of their life in water and part on land. There are three major groups of amphibians: salamanders, frogs, and toads, and caecilians. Salamanders, frogs, and toads can be found in Olympic National Park (ONP), but caecilians live only in tropical regions. Many amphibians are generalist predators, eating almost any prey they can fit into their mouths.

    CIF (chip-in-flex) and COF (chip-on-flex) packages have the advantages of fine pitch capability, and flexibility. Anisotropic conductive films (ACFs) are used for the interconnection between chip and substrate. Display, mobile device, and semiconductor industry require for smaller and more integrated packages. Both CIF and COF packages are an alternative for the demands. However, there are some reliability problems of interconnection between the chip and substrate because the packages are subjected to various loading conditions. These may degrade the functionality of the packages. Therefore, reliability assessment of both packages is necessary. In this study, experimental tests were performed to evaluate the reliability of interconnection between the chip and substrate of CIF and COF packages. Thermal cycling tests were performed to evaluate the resistance against thermal fatigue. The shape and warpage of the chip of CIF and COF packages were observed using optical methods (e.g., shadow Moiré and Twyman/Green interferometry). These optical Moiré techniques are widely used for measuring small deformations in microelectronic packages. The stress distribution around the chip was evaluated through FEA (finite element analysis). In addition, we suggested modifying design parameter of CIF packages for the reliability enhancement.

    Fitch, Kenneth D

    2017-11-01

    The objective of this paper was to review our knowledge of athletes who have, are believed to have or have attempted to engage in blood doping to enhance their performance at an Olympic Games. The paper focused on the Games from Munich 1972 to London 2012 and the author had a medical role at each of the Olympics that is discussed. The study revealed that Olympic athletes have benefitted from manipulating their blood by re-infusion of autologous or infusion of homologous blood and by administering erythropoiesis stimulating agents, notably the three generations of erythropoietins. Fifty seven athletes have been sanctioned with 12 athletes forfeiting 17 Olympic medals including 12 gold medals because of blood doping. Until 1986, the infusion of blood was not prohibited in sport but considered unethical. Erythropoietin was prohibited by the International Olympic Committee's Medical Commission in 1990. There has been a change as to how Olympic athletes have enhanced performance by blood doping, commencing with blood infusion and later administering erythropoiesis stimulating agents and significant advances have occurred in detecting such misuse. Currently, the hematological component of World Anti-Doping Agency's athlete biological passport is an important but not infallible mechanism to identify athletes who cheat by blood doping.

    Zika virus (ZIKV) is an arthropod-borne virus that is mainly transmitted via a bite from a female mosquito of the Aedes species. However, ZIKV can be transmitted sexually or via blood. Due to the recent ZIKV outbreak in South and Central America, many national and international organizations are concerned about the safety of athletes, coaches, staff, and spectators during the Olympic and Paralympic Games. Infected individuals are generally asymptomatic or have mild symptoms. However, ZIKV infection can potentially cause serious complications such as Guillain-Barre syndrome and congenital defects. Preferred diagnosis is based on real-time reverse-transcription polymerase chain reaction from blood and urine. Currently, there is no treatment or immunization available for ZIKV infection, and disease control is limited to preventing mosquito bites.

  12. The Olympics and harm reduction?

    PubMed Central

    2012-01-01

    The current anti-doping policy (‘war on doping’) resembles the ‘war on drugs’ in several aspects, including a zero-tolerance approach, ideology encroaching on human rights and public health principles, high cost using public money for repression and control, and attempts to shape internationally harmonized legal frameworks to attain its aim. Furthermore, even if for different reasons, both wars seem not to be able to attain their objectives, and possibly lead to more harm to society than they can prevent. The Olympic buzz is mounting and we can expect multiple headlines in the media on doping and anti-doping stories related to this event. In this article we describe current anti-doping policy, reflect on its multiple unplanned consequences, and end with a discussion, if lessons learned from harm reduction experiences in the illicit drugs field could be applied to anti-doping.

    Kenny, Kevin B.; Lin, Kwei-Jay

    1991-01-01

    The design and implementation of a real-time programming language called Flex, which is a derivative of C++, are presented. It is shown how different types of timing requirements might be expressed and enforced in Flex, how they might be fulfilled in a flexible way using different program models, and how the programming environment can help in making binding and scheduling decisions. The timing constraint primitives in Flex are easy to use yet powerful enough to define both independent and relative timing constraints. Program models like imprecise computation and performance polymorphism can carry out flexible real-time programs. In addition, programmers can use a performance measurement tool that produces statistically correct timing models to predict the expected execution time of a program and to help make binding decisions. A real-time programming environment is also presented.

    The Summer Olympic Games constitute the biggest concentration of human sports and activities in a particular place and time since 776 BCE, when the written history of the Olympic Games in Olympia began. Summer and Winter Olympic anti-doping laboratories, accredited by the International Olympic Committee in the past and the World Anti-Doping Agency in the present times, acquire worldwide interest to apply all new analytical advancements in the fight against doping in sports, hoping that this major human event will not become dirty by association with this negative phenomenon. This article summarizes the new analytical progresses, technologies and knowledge used by the Olympic laboratories, which for the vast majority of them are, eventually, incorporated into routine anti-doping analysis.

    Background The Olympic Games constitute a first-class opportunity to promote athleticism and health messages. Little is known, however on the impact of Olympic Games on the development of health-promotion programs for the general population. Our objective was to identify and describe the population-based health-promotion programs implemented in relation to the Athens 2004 Olympic and Para Olympic Games. Methods A cross-sectional survey of all stakeholders of the Games, including the Athens 2004 Organizing Committee, all ministries of the Greek government, the National School of Public Health, all municipalities hosting Olympic events and all official private sponsors of the Games, was conducted after the conclusion of the Games. Results A total of 44 agencies were surveyed, 40 responded (91%), and ten (10) health-promotion programs were identified. Two programs were implemented by the Athens 2004 Organizing Committee, 2 from the Greek ministries, 2 from the National School of Public Health, 1 from municipalities, and 3 from official private sponsors of the Games. The total cost of the programs was estimated at 943,000 Euros; a relatively small fraction (0.08%) of the overall cost of the Games. Conclusion Greece has made a small, however, significant step forward, on health promotion, in the context of the Olympic Games. The International Olympic Committee and the future hosting countries, including China, are encouraged to elaborate on this idea and offer the world a promising future for public health.

    To design and develop the fourth generation in endoscopy after the rigid, semirigid and flexible instruments. This next generation technology has been named SolidFlex, and it was designed by a surgeon based on many years of research with the objective to provide easier and faster solutions for physicians when performing endoscopic procedures. This new endoscope called SolidFlex has been brought to light with the latest technology to provide surgeons of every age the capabilities to carry out any possible endoscopic procedure. SolidFlex is state-of-the-art in both design and construction, giving the the weight of the usual flexible endoscope. The Instrument is ergonomic, intuitive (instinctive perception) and coherent, meaning that the handle control moves the instrument's active flexible section towards predictable, pre-selected areas, driving the procedure fluidly throughout. It provides the stability of a rigid and semirigid instrument with the exploration capabilities of the flexible endoscope in order to achieve the best means of rendering a patient 100% stone free. The SolidFlex ureteroscope prototype has retrieved urinary stones in 9 patients and 11 renal units. These procedures were divided in two groups: Group I, pre-stented after double "J" withdrawal for a previous renal colic episode. Group II, during the acute renal colic episode. Ureteral dilatation was carried out only in Group II and after dilatation in both groups, insertion up to the renal pelvis or the area were the obstruction was present, took only a matter of 15 seconds at the most. All procedures could be completed in each group and stones in the renal papilla from 200 nm, to 4 mm in any given papilla were removed either by laser energy, retrieved with a basket or both. Patients did not experience any pain or major discomfort after the procedure, and no analgesic medication was required, nor requested by any of the patients. The new SolidFlex technology has been tested in surgery and proven to

    This work describes the fabrication and characterization of a Niobium on polyimide flex cable suitable for sub-Kelvin temperatures. The processing used can be extended to high density interconnects and allows for direct integration with printed circuit boards. Several key parameters such as RRR, Tc, current carrying capability at 4 K and thermal conductivity in the range from 0.15 to 10 K have been measured. The average Tc was found to be 8.9 K, with a minimum of 8.3 K. Several samples allowed for more than 50 mA current at 4 K while remaining in the superconducting state. The thermal conductivity for this flex design is dominated by the polyimide, in our case Pyralin PI-2611, and is in good agreement with published thermal conductivity data for a polyimide called Upilex R.

    The present ground based investigations give the first definitive look describing the charging behavior of Orion UltraFlex arrays in both the Low Earth Orbital (LEO) and geosynchronous (GEO) environments. Note the LEO charging environment also applies to the International Space Station (ISS). The GEO charging environment includes the bounding case for all lunar mission environments. The UltraFlex photovoltaic array technology is targeted to become the sole power system for life support and on-orbit power for the manned Orion Crew Exploration Vehicle (CEV). The purpose of the experimental tests is to gain an understanding of the complex charging behavior to answer some of the basic performance and survivability issues to ascertain if a single UltraFlex array design will be able to cope with the projected worst case LEO and GEO charging environments. Stage 1 LEO plasma testing revealed that all four arrays successfully passed arc threshold bias tests down to -240 V. Stage 2 GEO electron gun charging tests revealed that only the front side area of indium tin oxide coated array designs successfully passed the arc frequency tests

  4. An aerodynamic study on flexed blades for VAWT applications

    NASA Astrophysics Data System (ADS)

    Micallef, Daniel; Farrugia, Russell; Sant, Tonio; Mollicone, Pierluigi

    2014-12-01

    There is renewed interest in aerodynamics research of VAWT rotors. Lift type, Darrieus designs sometimes use flexed blades to have an 'egg-beater shape' with an optimum Troposkien geometry to minimize the structural stress on the blades. While straight bladed VAWTs have been investigated in depth through both measurements and numerical modelling, the aerodynamics of flexed blades has not been researched with the same level of detail. Two major effects may have a substantial impact on blade performance. First, flexing at the equator causes relatively strong trailing vorticity to be released. Secondly, the blade performance at each station along the blade is influenced by self-induced velocities due to bound vorticity. The latter is not present in a straight bladed configuration. The aim of this research is to investigate these effects in relation to an innovative 4kW wind turbine concept being developed in collaboration with industry known as a self-adjusting VAWT (or SATVAWT). The approach used in this study is based on experimental and numerical work. A lifting line free-wake vortex model was developed. Wind tunnel power and hot-wire velocity measurements were performed on a scaled down, 60cm high, three bladed model in a closed wind tunnel. Results show a substantial axial wake induction at the equator resulting in a lower power generation at this position. This induction increases with increasing degree of flexure. The self-induced velocities caused by blade bound vorticity at a particular station was found to be relatively small.

    One of the main motivation of the experiments at the Large Hadron Collider (LHC), scheduled to start around 2006, is to search for supersymmetric particles. The region of the parameter space of the minimal supersymmetric standard model, where supersymmetry can be discovered is investigated. We show that if supersymmetry exists at electroweak scale, it would be easy to find signals for it at the LHC. If the LHC does find supersymmetry, this would be one of the greatest achievements in the history of theoretical physics.

    In preparation for the 2008 Beijing Olympic Games, Chinese authorities undertook a range of measures to strengthen food safety along the entire food supply continuum from production to consumption to protect the large number of athletes and spectators anticipated. In addition, food safety promotion campaigns targeting Olympic visitors as well as Beijing residents were carried out. Based on an assessment of various indicators, these efforts were successful in reducing the risk of foodborne disease during the Beijing Olympics and promoting safer food for Beijing residents. The food safety experiences of the 2008 Beijing Olympics might be usefully applied to major sporting events and mass gatherings in the future.

  10. Nearshore wave-induced cyclical flexing of sea cliffs

    2005-01-01

    [1] Evolution of a tectonically active coast is driven by geomorphically destructive energy supplied by ocean waves. Wave energy is episodic and concentrated; sea cliffs are battered by the geomorphic wrecking ball every 4-25 s. We measure the response of sea cliffs to wave assault by sensing the ground motion using near-coastal seismometers. Sea cliffs respond to waves in two distinct styles. High-frequency motion (20 Hz) reflects the natural frequency of the sea cliff as it rings in response to direct wave impact. Low-frequency motion in the 0.1-0.05 Hz (10-20 s) band consistently agrees with the dominant nearshore wave period. Integrating microseismic velocities suggests 50 ??m and 10 ??m displacements in horizontal and vertical directions, respectively. Displacement ellipsoids exhibit simultaneous downward and seaward sea cliff motion with each wave. Video footage corroborates the downward sea cliff flex in response to the imposed water load on the wave cut platform. Gradients in displacement amplitudes documented using multiple seismometers suggest longitudinal and shear strain of the flexing sea cliff on the order of 0.5-4 ?? strains during each wave loading cycle. As this sea cliff flexure occurs approximately 3 million times annually, it has the potential to fatigue the rock through cyclical loading. Local sea cliff retreat rates of 10 cm/yr imply that a given parcel of rock is flexed through roughly 109 cycles of increasing amplitude before exposure to direct wave attack at the cliff face.

    The GalaFLEX Scaffold (Galatea Surgical, Inc., Lexington, MA) for plastic and reconstructive surgery belongs to a new generation of products for soft tissue reinforcement made from poly-4-hydroxybutyrate (P4HB). Other members of this new family of products include MonoMax Suture (Aesculap AG, Tuttlingen, Germany) for soft tissue approximation, BioFiber Scaffold (Tornier, Inc., Edina, MN) for tendon repair, and Phasix Mesh (C.R. Bard, Inc., Murray Hill, NJ) for hernia repair. Each of these fully resorbable products provides prolonged strength retention, typically 50% to 70% strength retention at 12 weeks, and facilitates remodeling in vivo to provide a strong, lasting repair. P4HB belongs to a naturally occurring class of biopolymers and fibers made from it are uniquely strong, flexible, and biocompatible. GalaFLEX Scaffold is comprised of high-strength, resorbable P4HB monofilament fibers. It is a knitted macroporous scaffold intended to elevate, reinforce, and repair soft tissue. The scaffold acts as a lattice for new tissue growth, which is rapidly vascularized and becomes fully integrated with adjacent tissue as the fibers resorb. In this review, we describe the development of P4HB, its production, properties, safety, and biocompatibility of devices made from P4HB. Early clinical results and current clinical applications of products made from P4HB are also discussed. The results of post-market clinical studies evaluating the GalaFLEX Scaffold in rhytidectomy and cosmetic breast surgery demonstrate that the scaffold can reinforce lifted soft tissue, resulting in persistent surgical results in the face and neck at one year, and provide lower pole stability after breast lift at one year.

    We previously proposed a new bioinstrumentation using the shape deformation of the amputated upper limbs without using the myoelectricity generated on the skin of the upper limbs. However many electronic parts were required owing to a bridge circuit and multi-amplifier circuits so as to amplify a tiny voltage of strain gages. Moreover, the surplus heat might occur by the overcurrent owing to low resistance value of strain gages. Therefore, in this study, we apply a flex sensor to this system instead of strain gages to solve the above problems.

    2007-05-01

    The London 2012 Olympic and Paralympic Games have the unique potential to deliver sustainable sporting, social, cultural, economic and environmental legacies, not just for London as the host city, but for the whole of Britain. This article focuses primarily on the first three of these potential Olympics legacies. The first area explored is the social legacy as it impacts on host communities; second, the potential educational and cultural legacy of the 2012 Games are examined; and finally, there follows an overview of the health benefits that could result from a sustained increase in mass participation in sport, physical activity and exercise. This appraisal is undertaken through a review of existing Olympic literature and examples are drawn from previous summer and winter Games. This preliminary exploration is followed by the identification of some key challenges to be overcome if the opportunities available to a wide and diverse range of stakeholders are to be fully optimized. The article suggests that the 2012 Games can act as a catalyst for sports development throughout Britain, while also assisting with government cross-cutting agendas such as tackling crime, antisocial behaviour, developing healthy and active communities, improving educational attainment, and combating barriers to participation. In doing so, this article argues that priority should be placed at supporting grassroots sport through greater access to sport in the community, and not solely elite level sports development. The article concludes by suggesting that the 2012 Games provide opportunities to deliver real and tangible changes and most importantly, to afford a higher priority to sport, along with the obvious associated health benefits for Britain as a whole. The underlying challenge as we move towards 2012 is to achieve a positive step change in the attitudes towards sport and physical activity in British society. Achieving this would possibly be the greatest legacy of the 2012 Olympic and

    How to organise an appropriate team to provide quality dental care during the Olympic Games has become an important consideration for each successive host country. The aims of this study were to document dental services provided at the Olympic Games and to provide data for planning future events. SET-UP OF THE DENTAL CARE DEPARTMENT: There were six dental chairs in six independent treatment rooms, one technical laboratory, a sterilising room and an x-ray room equipped with one digital panoramic screening machine and one intraoral x-ray machine in the polyclinic in the Olympic Village in Beijing. Shifts comprised 80 dentists and 28 nurses who were organised into three shifts working from 08:00 until 23:00. In the 2008 Olympic Games, there were 1607 cases involving 1126 patients requiring dental care: 795 cases from 516 athletes; 483 cases from 370 coaches and other staff; and 99 cases from volunteers. Endodontic treatments, permanent fillings, oral hygiene, mouthguards and treatment of pericoronitis were the most frequent procedures in dental care. The Mouthguard Service was extremely popular and well utilised. 122 athletes received new custom-made mouthguards in Beijing. As the utilisation of the dental service grows, and the burden of providing care for such a large cohort increases, a well-organised dental team becomes increasingly important. More general-practice dentists were needed in the team. Different kinds of specialist were suggested for working in the team-for example, oral and maxillofacial surgeons, sport dentists for mouthguards and endodontists.

    The aim of this study was to describe an educational method teaching Disaster Medicine to American Emergency Medicine (EM) physicians and to evaluate knowledge attainment using this method. This was an observational study using a pre-test and a post-test. A full-scale disaster exercise (FSE) was conducted at a large academic center with two hospitals in Brooklyn, New York (USA). Eighty-two EM residents (physicians in training, post medical school) participated in the study. Inclusion criteria for study participation was all EM residents training at the State University of New York (SUNY) Downstate at the time of the study. There were no exclusion criteria. The exercise was a disaster drill designed as "Olympic Games." Participants in the exercise took a pre-test and a post-test. The primary outcome of the study was the mean difference between pre-test and post-test scores of the study participants using independent sample t-tests. Secondary outcomes of the study were percent of critical actions met by the residents and the hospitals as measured by direct observation of trained study personnel during the exercise. Mean resident post-test scores were higher than pre-test scores to a degree that was statistically significant (62% versus 53%; P =.002). The residents' performances ranged from 48% to 63% of objectives met. The hospitals' performances met 50% to 100% of their objectives. The use of an Olympic Games format was an effective model for disaster education for physicians. The model allowed for evaluation of performance and protocols of participants and hospital systems, respectively, and may be used objectively to evaluate for areas of improvement. The Disaster Olympics drill was found to improve emergency preparedness knowledge in the population studied and may constitute a novel and efficacious methodology in disaster training.

    Objective First, to document the injuries sustained during the 2004 Olympic Games in a sample of patients visiting the physiotherapy department of the Olympic Village polyclinic. Second, to provide information and data about the physiotherapy services for planning future Olympics and other mass gatherings. Design Observational study. Setting Olympic Village polyclinic. Participants 457 patients aged 15–72 years visited the physiotherapy department from 30 July through 30 August. Results The department's workload was at a peak during the last 15 days of the Olympic Games (periods B and C). The most common injuries were overuse injuries (47.3%). The most common pathology for physiotherapy attendance was myofascial pain/muscle spasm (32.5%), followed by tendinopathy (19.2%) and ligament sprain (18.7%). The most prevalent site of injury was the thigh (21%), followed by the knee (14.1%) and the lumbar spine (13.5%). Most injuries had symptoms of <7 days' duration. The geographical region with the greatest demand for physiotherapy services was Africa (40.6%). Most patients were athletes (74.8%), although team officials accounted for a considerable number (14%). Conclusions The smallest national teams—especially those from developing countries—were more likely to take advantage of services, probably because the larger teams had their own medical and physiotherapy staff. The characteristics of patients, their sustained injuries and the subsequent treatment varied by the accreditation status of the patients. The physiotherapy department's workload was dependent on the Olympic Games schedule. PMID:17502331

    The purpose of this study was to identify the characteristics of Olympic medal winners (gold, silver, bronze) who competed in the 2008 Beijing Olympic Games and compare these characteristics to those who competed but did not earn medals. We have also descriptively analysed the 2008 data in comparison to the 2004 data (Kazemi et al., 2009), and 2000 data (Kazemi et al., 2006) and summarized changes that were identified. This study as well as the last two studies did not find any statistically significant differences between winners and non-winners with regards to average age, weight, height and BMI. There are, however, some trends that were observed. Female winners were slightly younger, shorter, with greater BMI’s versus non-winners. There was a significant decrease in frequency of warnings from 2004 to 2008. Unlike 2004, the 2008 Olympic Taekwondo competitors used more defensive kicks to score. These suggest a shift from aggressive tactics to score to a more conservative one. PMID:21120015

    2015-11-01

    Guided by the notion of a trickle-down effect, the present study examines whether sport participation in Canada increased following the 2010 Winter Olympics in Vancouver. Comparing rates of sport participation prior to and following the Games using nationally representative data, the results suggest that the Olympics had almost no impact on sport participation in Canada, although there does appear to be a modest "bounce" in sport participation in the Vancouver area immediately following the Vancouver Games. As such, if the trickle-down effect did occur, the analysis suggests that the effect was locally situated, short-lived, and small.

    Endoscopic endonasal surgery is currently regarded as the 'gold standard' for operating on pituitary gland tumors, and is becoming more and more accepted for treatment of other skull base lesions. However, endoscopic surgical treatment of most skull base pathologies, including certain pituitary tumors, is severely impaired by current instruments lack of maneuverability. Especially, gaining access to, and visibility of, difficult-to-reach anatomical corners without interference with surrounding neurovascular structures or other instruments, is a challenge. In this context there is the need for instruments that are able to provide a stable shaft position, while both the orientation and the position of the end-effector can be independently controlled. Current instruments that allow for this level of maneuverability are usually mechanically complex, and hence less suitable for mass production. This study therefore focuses on the development of a new actuation technique that allows for the required maneuverability while reducing the construction complexity. This actuation technique, referred to as multi-actuation, integrates multiple cable routings into a single steerable structure. Multi-actuation has been successfully integrated and tested in a handheld prototype instrument called HelixFlex. HelixFlex contains a 4 degrees of freedom maneuverable 5.8 mm (diameter) tip and shows promising results concerning its maneuverability and potential rigidity.

    The objective of this study was to briefly review air pollution and its effects on athletes' health and performance and to examine air quality (AQ) at specific Olympic Summer Games between 1964 and 2008. It will focus on any attempts made by the cities hosting these Olympics to improve AQ for the Games and if undertaken, how successful these were. The author had a medical role at five of the seven Olympic Games that will be examined and hence has personal experiences. Information was obtained from the readily accessible official reports of the Olympic Games, relevant published papers and books and the internet. For each of these seven Olympic Games, monitoring AQ was far below current acceptable standards and for the majority, minimal or no data on major pollutants was available. From what can be ascertained, at these Games, AQ varied but was less than optimal in most if not all. Nevertheless, there were few reported or known unfavorable effects on the health of Olympic athletes. To date, there have been few reported consequences of sub-optimal AQ at Olympic Games. The focus on AQ at Olympic Games has gradually increased over the past five decades and is expected to continue into the future.

    The Olympic Games constitutes the world's largest sporting event. Nurses play an important, but poorly discussed, role in emergency care, routine clinical care and preventive care for athletes from many cultures as well as an enormous influx of spectators. In this article, we discuss five important considerations when preparing nurses to provide safe care for Olympians: elite athletes as a cultural group; caring for the Olympic family; disaster preparedness and security; infection control; and principles of transcultural nursing. Because of the nature of the sports and types of injuries and the effects of climate, these challenges differ somewhat between the summer and winter Olympics. Nevertheless, the Olympic games provide a tremendous opportunity to experience transcultural nursing and to highlight how nurses play a significant role in the care of the athletes, the Olympic family, and the spectators. © 2015 Wiley Publishing Asia Pty Ltd.

    Athletes report frequent use of various dietary supplements (DSs). However, no study has examined DS use and antidoping knowledge in Korean Olympians. The objectives of this study were to obtain information about Korean Olympians' DS use during the training period for the Beijing 2008 Summer Olympic Games and immediately before their Olympic events, to obtain DS-intake reasons and DS providers, and to obtain information on athletes' doping education, knowledge, and educators. Korean Olympians completed 2 questionnaires 1 wk before the opening and within 1 wk after the closing of the Beijing 2008 Summer Olympic Games. Results showed that 79% of male and 82% of female Olympians take more than 1 DS during the training period and that vitamins and Oriental supplements are the 2 top-ranked DSs. Reasons for DS use were to improve recovery ability (66%) and muscle performance (22%), and sources of obtaining DSs were parents (36%) and coaches (35%). Furthermore, 79% of Korean Olympians reported receiving regular education on antidoping regulations from Olympic-sponsored education classes (64%) and coaches (15%). In conclusion, this study was the first to examine DS use and antidoping-related information in Korean Olympians. Because some herbal products contain substances banned by the World Anti-Doping Agency, athletes should be cautious in using mixed Oriental supplements.

    Stemming from the need to prevent, detect and suppress on-board spacecraft fires, the NASA microgravity combustion research program has grown to include fundamental research. From early experiment, we have known that flames behave differently in microgravity, and this environment would provide an ideal laboratory for refining many of the long held principals of combustion science. A microgravity environment can provide direct observation of phenomena that cannot be observed on Earth. Through the years, from precursor work performed in drop towers leading to experiments on the International Space Station (ISS), discoveries have been made about the nature of combustion in low gravity environments. These discoveries have uncovered new phenomena and shed a light on many of the fundamental phenomena that drive combustion processes. This paper discusses the NASA microgravity combustion research program taking place in the ISS Combustion Integrated Rack, its various current and planned experiments, and the early results from the Flame Extinguishment (FLEX) Experiment.

    2015-01-01

    The Selective Laser Melting (SLM) manufacturing technique has been utilized in the manufacture of a flex joint typical of those found in rocket engine and main propulsion system ducting. The SLM process allowed for the combination of parts that are typically machined separately and welded together. This resulted in roughly a 65% reduction of the total number of parts, roughly 70% reduction in the total number of welds, and an estimated 60% reduction in the number of machining operations. The majority of the new design was in three SLM pieces. These pieces, as well as a few traditionally fabricated parts, were assembled into a complete unit, which has been pressure tested. The design and planned cryogenic testing of the unit will be presented.

    There are no published data on the reliability of competitive strength performance, even though it has a pronounced effect on athletes' medal prospects and the ability of coaches and athletes to identify factors that affect competitive performance. The purpose of this investigation was to analyze the reliability of elite olympic weightlifters over a series of international weightlifting meets. We obtained official results of international competitions over an 18-month period from 1999 until the 2000 Olympic Games at the International Weightlifting Federation website. The measure of reliability was the typical within-athlete variation, derived as the coefficient of variation (CV) by 2-way analysis of variance of log-transformed weights lifted for the snatch, clean and jerk, and total. The results of this analysis were (a) within-athlete variations were as follows: snatch, 2.7% (95% likely range, 2.4-3.2%); clean and jerk, 2.3% (1.7-3.6%); total weight lifted, 2.5% (2.2-2.9%); (b) men and women: the variation was higher for the women compared with the men in both snatch (ratio of CV, 1.4) and clean and jerk (ratio of CV, 1.5), and for the total weight lifted (ratio of CV, 1.3); and (c) the top 5 athletes were almost always more reliable than the bottom-half athletes. Recent work has shown that the smallest worthwhile performance is about half the within-athlete variation, so coaches and sport scientists should focus on enhancements of as little as 1.2% in total weight lifted for elite olympic weightlifters.

One hundred and two athletes competed (54 males and 48 females) in the Games. The mean average age and BMI (Body Mass Index) of 16 male winners was 24.4 ± 3.3 years and 21.9 ± 2.4 respectively compared to 25.2 ± 4.3 years and 22.8 ± 3.3 for the 38 male non-winners. The mean average age and BMI of the 16 female winners was 23.1 ± 3.9 years and 20.8 ± 2.3 respectively compared to 24.9 ± 4.7 years and 21.3 ± 2.7 for the 32 female non-winners. For all four types of athletes, offensive kicks accounted for at least 52% of the techniques to score a point. Ninety-eight percent of all techniques used to score were kicks. Although not statistically significant, winners overall tended to be younger in age and taller with slightly lower BMI than their weight category average. Taking into account the literature cited in this article, future studies should be designed to examine the relationship between performance and functional variables such as muscle power, muscle endurance, reaction time and aerobic capacity. Key Points Winners tended to be younger in age and taller with slightly lower BMI than their weight category average. An offensive technique was used to score slightly more often than a defensive one. Overall, 98% of all techniques used to score were kicks. PMID:24357983

    This paper is about the design and implementation of an examination system based on World Wide Web. It is called FLEX-Flight License Exam Software. We designed and implemented flexible and modular software architecture. The implemented system has basic specifications such as appending questions in system, building exams with these appended questions and making students to take these exams. There are three different types of users with different authorizations. These are system administrator, operators and students. System administrator operates and maintains the system, and also audits the system integrity. The system administrator can not be able to change the result of exams and can not take an exam. Operator module includes instructors. Operators have some privileges such as preparing exams, entering questions, changing the existing questions and etc. Students can log on the system and can be accessed to exams by a certain URL. The other characteristic of our system is that operators and system administrator are not able to delete questions due to the security problems. Exam questions can be inserted on their topics and lectures in the database. Thus; operators and system administrator can easily choose questions. When all these are taken into consideration, FLEX software provides opportunities to many students to take exams at the same time in safe, reliable and user friendly conditions. It is also reliable examination system for the authorized aviation administration companies. Web development platform - LAMP; Linux, Apache web server, MySQL, Object-oriented scripting Language - PHP are used for developing the system and page structures are developed by Content Management System - CMS.

    BACKGROUND: Beijing successfully hosted the 2008 Olympic Games, and the services including medical services were widely appreciated by both participants and visitors. We retrospectively analyzed the quality of the medical services provided to athletes, spectators, VIPs, and the workforce during the Beijing 2008 Olympic Games. The information thus gathered would be useful for planning strategies for managing mass gatherings. METHODS: Medical encounter forms filled during the Beijing 2008 Olympic Games were retrospectively reviewed. Descriptive statistics was used to characterize the data by accreditation and diagnostic categories. RESULTS: A total of 22 892 medical encounters were documented during the Beijing 2008 Olympic Games. Among them, 10 549 (46.08%) involved the workforce, 3 365 (14.70%) athletes, 3 019 (13.19%) spectators, 585 (2.56%) members of the media, 1 065 (4.65%) VIPs, and 4 309 (18.82%) others. Of the 22 892 cases, physical injury accounted for 27.90% (6 386), respiratory disease 18.21% (4 169), and heat-related illnesses 2.68% (615). CONCLUSIONS: Preparations of the medical service for the Beijing 2008 Olympic Games were made for 7 years, and the service provided has been praised worldwide. This study provides valuable information that may be useful for planning medical services for upcoming Olympic Games, including the London 2012 Olympic Games and other mass gatherings. PMID:25215021

  15. Scenarios for sLHC and vLHC

    2008-03-01

    The projected lifetime of the LHC low-beta quadrupoles and evolution of the statistical error halving time call for an LHC luminosity upgrade by the middle of the coming decade. In the framework of the EU CARE-HHH network, two scenarios have been developed for increasing the LHC peak luminosity by a factor 10, to 10 cms ("sLHC"). Both scenarios imply a rebuilding of the high-luminosity interaction regions (IRs) in combination with a consistent change of beam parameters. However, their respective features, bunch structures, IR layouts, merits and challenges differ substantially. In either scenario luminosity leveling during a store would be advantageous for the physics experiments. Longer-term R&D efforts are devoted to a higher-energy hadron collider ("vLHC"), which could be realized on a green field or as a later and more radical LHC upgrade.

  16. LHC Nobel Symposium Proceedings

    In the summer of 2012, a great discovery emerged at the Large Hadron Collider (LHC) at CERN in Geneva. A plethora of new precision data had already by then been collected by the ATLAS and CMS experiments at LHC, providing further extensive support for the validity of the Standard Model of particle physics. But what now appeared was the first evidence for what was not only the last unverified prediction of the Standard Model, but also perhaps the most decisive one: the prediction made already in 1964 of a unique scalar boson required by the theory of François Englert and Peter Higgs on how fundamental particles acquire mass. At that moment in 2012, it seemed particularly appropriate to start planning a gathering of world experts in particle physics to take stock of the situation and try to answer the challenging question: what next? By May 2013, when the LHC Nobel Symposium was held at the Krusenberg Mansion outside Uppsala in Sweden, the first signs of a great discovery had already turned into fully convincing experimental evidence for the existence of a scalar boson of mass about 125 GeV, having properties compatible with the 50-year-old prediction. And in October 2013, the evidence was deemed so convincing that the Swedish Royal Academy of Sciences awarded the Nobel Prize in Physics to Englert and Higgs for their pioneering work. At the same time the search at the LHC for other particles, beyond those predicted by the Standard Model, with heavier masses up to—and in some cases beyond—1 TeV, had provided no positive result. The triumph of the Standard Model seems resounding, in particular because the mass of the discovered scalar boson is such that, when identified with the Higgs boson, the Standard Model is able to provide predictions at energies as high as the Planck mass, although at the price of accepting that the vacuum would be metastable. However, even if there were some feelings of triumph, the ambience at the LHC Nobel Symposium was more one of

  1. Analysing Olympic Games through dominance networks

    2016-11-01

    The aim of this paper is to assess the results/performance of countries in the Olympic Games, taking into account their size and resources. A complex network analysis approach is proposed. The first step is to build the dominance network, which is a weighted directed graph in which nodes represent the participating nations and the arc length between any two nations measures the weighted difference in the number of medals won by both countries. An arc from a country to another b exists only if the latter has won more medals than the former and, in addition, it is smaller in population and in terms of GDP. In other words, an arc between two nodes exists if the origin nation performs worse than the destination when, given the population and GDP of both countries, it should have performed better (or at least equally). This dominance network has transitive links and a layered structure and, apart from being visualized, it can be characterized using different complex network measures. The results of the Beijing 2008 Olympic Games are used to illustrate the proposed approach.

    This paper examines some of the medical problems arising from the successful deployment of Defence Medical Services personnel to Op OLYMPICS (mid-June 2012-September 2012). It does not aim to be all encompassing in its scope, but focuses on the most pressing issues affecting a junior military doctor's ability to work effectively under field conditions. This will entail a discussion about whether in a deployment such as Op OLYMPICS medical care should be based upon offering solely primary healthcare in medical centres or using Role 1 medical treatment facilities, which include primary healthcare and pre-hospital emergency care. The main recommendations arising from the deployment are: clinicians should deploy with a minimum of basic emergency drugs and equipment; a medical facility treating a large population at risk for a prolonged period should have a broad stock of medications available on site; and medical risk assessments must be performed on all Reservists during mobilisation.

  3. Adapting to climate change at Olympic National Forest and Olympic National Park

    2011-01-01

    Climate change presents a major challenge to natural resource managers both because of the magnitude of potential effects of climate change on ecosystem structure, processes, and function, and because of the uncertainty associated with those potential ecological effects. Concrete ways to adapt to climate change are needed to help natural resource managers take the first steps to incorporate climate change into management and take advantage of opportunities to counteract the negative effects of climate change. We began a climate change adaptation case study at Olympic National Forest (ONF) in partnership with Olympic National Park (ONP) to determine how to adapt management of federal lands on the Olympic Peninsula, Washington, to climate change. The case study began in the summer of 2008 and continued for 1½ years. The case study process involved science-based sensitivity assessments, review of management activities and constraints, and adaptation workshops in each of four focus areas (hydrology and roads, fish, vegetation, and wildlife). The process produced adaptation options for ONF and ONP, and illustrated the utility of place-based vulnerability assessment and science-management workshops in adapting to climate change. The case study process provides an example for other national forests, national parks, and natural resource agencies of how federal land management units can collaborate in the initial stages of climate change adaptation. Many of the ideas generated through this process can potentially be applied in other locations and in other agencies

Results were then compared to adult Taekwondo Olympic athletes in 2000, 2004 and 2008. Data on 96 Taekwondo athletes were obtained from the official Youth Olympic website. A LOGIT analysis was performed on the following six independent variables: height, body mass, body mass index, gender, techniques used to score, and warnings obtained during a match. The study did find some differences between winners and non-winners for males and female, although none of the differences were statistically significant. Consequently, training personnel may enhance winning potential of Taekwondo competitors by focusing on offensive versus defensive techniques and improving the quality of punching.

    Special Olympics is an international program of physical fitness, recreation and sports for the handicapped of all ages and provides competition at all ability levels by grouping participants into divisions according to age, sex and performance ability. Special Olympics, a year-round program of physical training for mentally handicapped children and adults, contributes positively to the physical, social and psychological development of these individuals. Special Olympic participants must have a physical examination prior to the training activities or athletic competition to determine limitations and to prescribe special precautions to follow while participating. School nurse practitioners play an important role in seeing that physical examinations are completed prior to scheduled events in addition to identifying immediate health needs, counseling students, teachers and parents about specific problems, updating medical information and seeking appropriate referrals for the participants. School nurse practitioners' attendance at Special Olympics competition is vital to the success of the program.

    The Beijing Olympics will be the world's premier sporting event in 2008. Countries should begin planning for appropriate support for their Olympic athletes. Experienced medical staff should be appointed early and become familiar with the major medical or injury concerns of athletes and officials. Teams should assemble a comprehensive medical kit. Appropriate medical advice can ensure that athletes will arrive in Beijing in optimal condition. Medical issues particularly relevant to competitors at the Beijing Olympics include heat and humidity, waterborne diseases and air pollution. However, the air pollution probably represents less of a threat than previous media reports would indicate. The Olympic village and venues can be thought of as small enclaves located within a rapidly developing country.

    In view of the role of hemoglobin in oxygen transport, the hemoglobin concentration in whole blood may indicate readiness for maximal physical performance. Hemoglobin concentrations were determined in members of the 1976 Canadian Olympic team and compared with those of the 1975 Canadian general population and with published data for the 1968 Australian and Dutch Olympic teams. The mean hemoglobin concentrations of the 123 male and 64 female Canadian Olympic athletes were 14.7 +/- 1.0 and 12.9 +/- 0.7 g/dL, respectively. Both male and female Canadian Olympic athletes had significantly lower (P less than 0.01) values than the other three groups. The suboptimal hemoglobin concentrations may be related to inadequate dietary intake of protein and iron. PMID:902207

    The Sydney Olympic and Paralympic Games will be held in September-October 2000, which is early to mid-spring in the southern hemisphere. Pollen-sensitive athletes may encounter problems with allergic symptoms triggered by pollen exposure, thus compromising their ability to attain peak performance. We sought to monitor pollen levels at the major Olympic venues to provide information for allergic athletes and their team doctors in order to adequately prepare them for Olympic competition. We performed aerobiologic monitoring of the major Olympic venues to provide a profile of the most prevalent pollen species appearing during the spring. In the second part of this study, we surveyed a population of elite Australian athletes from Olympic sports to ascertain the prevalence of allergic rhinoconjunctivitis, to investigate the major allergens involved in sensitization, and to conduct a pilot study to assess the effect of allergic rhinoconjunctivitis on quality of life. The pollen counts obtained at the 3 major sites were high over the period of Olympic competition. Tree pollens appeared from July, and grasses appeared from early September and peaked in the second week of October, the beginning of Paralympic competition. A relatively small number of pollen varieties comprise the majority of the total pollen count. Two hundred fourteen athletes (61% male; mean age, 21 +/- 16 years) representing 12 Olympic sports participated in the study. Fifty-six percent gave a symptom history consistent with allergic rhinoconjunctivitis, 41% had symptoms of allergic rhinoconjunctivitis and a positive test response to any one allergen, and 29% had seasonal allergic rhinoconjunctivitis (a positive history and at least one positive skin prick test response to a seasonal allergen). Athletes from aquatic sports were more likely to have symptoms than those from other sports. Symptom scores were higher and quality of life ratings were poorer in allergic compared with nonallergic athletes over

    One of the most enduring symbols of the Olympics is the torch or flame, an icon of peace and sportsmanship that has its roots in Ancient Greece. According to the Creed of the Olympics: "The important thing in the Games is not winning, but taking part. The essential thing is not conquering. but fighting well." The modern Olympic Games (1896-2000) have been heavy laden with controversy, as athletes have abused performance enhancing drugs to thrust themselves into the limelight in search of gold. It was not until 1967 that the International Olympic Medical Commission began banning drugs. Full-scale drug testing was instituted in 1972.: Retrospective review of modern summer and winter Olympics Game sources (1896-2002) was done for documentation of drug abuse, drug-related overdoses, and positive drug screens. Data were collected for the type of drug documented. the athlete's name, their country of origin, and Olympic event. Seventy cases were identified. The most common class of agents were steroids (29), followed by stimulants (22), diuretics (7), beta-2 agonists (2), and beta blockers (1). Alcohol and marijuana, while not historically prohibited, have been outlawed by several individual sport federations. Toxicities of these 2 agents were most likely under-reported. Countries of origin of individual athletes included Bulgaria (7), USA (7), Sweden (4), Spain (4), Japan (2), Poland (2), Greece (2), Canada (2), Hungary (2), Russia (2), Austria (2), and Great Britain, Norway, Romania, Armenian, and Latvian, each with 1. The most common Olympic events in which drug abuse was documented were weightlifting (25), trackand field (12), skiing (5), wrestling (5), volleyball (3), modern pentathlon (3), cycling (2), swimming (2), gymnastics (1), and rowing (1). As athletic pressures and financial gains of the Olympic Games heighten, more toxicities are likely to occur despite attempts at restricting performance-enhancing drugs.

    Size fractionated particulate matter (PM) samples (including PM2.5 and PM10) were collected at Peking University in Northwestern Beijing, China for a 2 week period prior to the Olympics, during the 2 week period of the Olympics, and for a 4 week period following the 2008 Olympics, during both source control and nonsource control periods. PM10 concentrations in this study were high correlated with, but a factor of 1.3 times higher than, the Beijing Environmental Protection Bureau's PM10 concentrations at near-by sites because of differences in the measurement methods used. The mean PM2.5 and PM10 concentrations were statistically different, and lower by 31 and 35%, during the Olympic period compared to the non-Olympic period. However, the PM concentrations were not statistically different between the source control and nonsource control periods. While meteorological parameters (air masses from the south and precipitation) accounted for 40% of the total variation in PM10 concentration, source control accounted for 16%, suggesting that meteorology accounted for more of the variation in PM concentration than source control measures. The PM10 concentrations in Beijing during the Olympic period were 2.9, 3.5, and 1.9 times higher than those in Atlanta, Sydney, and Athens. In addition, the PM2.5 and PM10 concentrations during the Olympic period exceeded the WHO 24-h guideline 100% and 81% of the time, respectively. Finally, the PM10 concentrations in October, November, and December 2008 were reduced by 9-27% compared to the same months in 2007, suggesting that the Olympic source control efforts (and possibly a down turn in the economy) have resulted in lower PM10 concentrations in Beijing.

  16. The force on the flex: Global parallelism and portability

    NASA Technical Reports Server (NTRS)

    Jordan, H. F.

    1986-01-01

    A parallel programming methodology, called the force, supports the construction of programs to be executed in parallel by an unspecified, but potentially large, number of processes. The methodology was originally developed on a pipelined, shared memory multiprocessor, the Denelcor HEP, and embodies the primitive operations of the force in a set of macros which expand into multiprocessor Fortran code. A small set of primitives is sufficient to write large parallel programs, and the system has been used to produce 10,000 line programs in computational fluid dynamics. The level of complexity of the force primitives is intermediate. It is high enough to mask detailed architectural differences between multiprocessors but low enough to give the user control over performance. The system is being ported to a medium scale multiprocessor, the Flex/32, which is a 20 processor system with a mixture of shared and local memory. Memory organization and the type of processor synchronization supported by the hardware on the two machines lead to some differences in efficient implementations of the force primitives, but the user interface remains the same. An initial implementation was done by retargeting the macros to Flexible Computer Corporation's ConCurrent C language. Subsequently, the macros were caused to directly produce the system calls which form the basis for ConCurrent C. The implementation of the Fortran based system is in step with Flexible Computer Corporations's implementation of a Fortran system in the parallel environment.

    This paper focuses on the development of a wearable sensor system to identify the different types of badminton grip that is used by a player during training. Badminton movements and strokes are fast and dynamic, where most of the involved movement are difficult to identify with the naked eye. Also, the usage of high processing optometric motion capture system is expensive and causes computational burden. Therefore, this paper suggests the development of a sensorized glove using flex sensor to measure a badminton player's finger flexion angle. The proposed Hand Monitoring Module (HMM) is connected to a personal computer through Bluetooth to enable wireless data transmission. The usability and feasibility of the HMM to identify different grip types were examined through a series of experiments, where the system exhibited 70% detection ability for the five different grip type. The outcome plays a major role in training players to use the proper grips for a badminton stroke to achieve a more powerful and accurate stroke execution.

    2008-01-01

    An optoelectronic metrology system is used for determining the attitude and flexing of a large spaceborne radar antenna or similar structure. The measurements are needed for accurate pointing of the antenna and correction and control of the phase of the radar signal wavefront. The system includes a dual-field-of-view star tracker; a laser ranging unit (LRU) and a position-sensitive-detector (PSD)-based camera mounted on an optical bench; and fiducial targets at various locations on the structure. The fiducial targets are illuminated in sequence by laser light coupled via optical fibers. The LRU and the PSD provide measurements of the position of each fiducial target in a reference frame attached to the optical bench. During routine operation, the star tracker utilizes one field of view and functions conventionally to determine the orientation of the optical bench. During operation in a calibration mode, the star tracker also utilizes its second field of view, which includes stars that are imaged alongside some of the fiducial targets in the PSD; in this mode, the PSD measurements are traceable to star measurements.

    This progress report summarizes the final year of activities of Phase I of the Olympic fisher restoration project. The intent of the Olympic fisher reintroduction project is to reestablish a self-sustaining population of fishers on the Olympic Peninsula. To achieve this goal, the Olympic fisher reintroduction project released 90 fishers within Olympic National Park from 2008 to 2010. The reintroduction of fishers to the Olympic Peninsula was designed as an adaptive management project, including the monitoring of released fishers as a means to (1) evaluate reintroduction success, (2) investigate key biological and ecological traits of fishers, and (3) inform future reintroduction, monitoring, and research efforts. This report summarizes reintroduction activities and preliminary research and monitoring results completed through December 2011. The report is non-interpretational in nature. Although we report the status of movement, survival, and home range components of the research, we have not completed final analyses and interpretation of research results. Much of the data collected during the monitoring and research project will be analyzed and interpreted in the doctoral dissertation being developed by Jeff Lewis; the completion of this dissertation is anticipated prior to April 2013. We anticipate that this work, and analyses of other data collected during the project, will result in several peer-reviewed scientific publications in ecological and conservation journals, which collectively will comprise the final reporting of work summarized here. These publications will include papers addressing post-release movements, survival, resource selection, food habits, and age determination of fishers.

    In our study, we set out to investigate whether there is a significant relationship between the count (raw rate) of suicides committed and the summer Olympic Games in such an achievement-oriented society like the Hungarian one, where summer Olympic Games receive extremely considerable attention. For our study, we examined the suicide cases occurring over 15706 days between 1 January 1970 and 31 December 2012 (43 years), separately for each gender. Because of the age-specific characteristics of suicide, the effect of the Olympic Games was analysed for the middle-aged (30-60 year-old) and the elderly (over 60 year-old) generations, as well as for the whole gender specific population. The role of the summer Olympic Games was examined with the help of time series intervention analysis after the cyclical and seasonal components have been removed. Based on our results, the effect of the Olympic Games is significant for the middle-aged (30-60 year-old) population. Neither in the older male, nor in any of the female age groups could a relationship between suicide and this sports event be detected. In summary, the Olympic Games seem to decrease the rate of suicide among middle-aged men slightly but significantly. In the interpretation of our results we emphasise the importance of the complex approach of suicidal behavior.

    This paper introduces the special issue of the British Journal of Sociology on the subject of the transnational aspects of Olympic and world sport. The special issue is underpinned by the perspective that because sport provides a space for the forging of transnational connections and global consciousness, it is increasingly significant within contemporary processes of globalization and the making of transnational society. In this article, we examine in turn eight social scientific themes or problems that are prominent within the special issue: globalization, glocalization, neo-liberal ideologies and policies, transnational society, securitization, global civil society, transnational/global public sphere, and fantasy/imagination. We conclude by highlighting five 'circles' of future research inquiry within world sport that should be explored by social scientists.

    The purpose of this study is to identify the characteristics of Tae kwon do champions (gold, silver, and bronze medalists) who competed in the Athens 2004 Olympic Games (N = 124) and compare these characteristics to those who competed but did not earn medals. All the data for the study was obtained from the official website of the 2004 Olympic Games www.athens2004.com and the following information was collected: weight category, weight, height, age, country representation, total points from kicks per weight category, total points from punches per weight category, total penalties per weight category, and type of win. The following descriptive statistics were calculated for each athlete according to gender: age, height, weight, and body mass index (BMI). No statistically significant differences exist between winners and non-winners with respect to age, height, weight and gender. Overall, male winners versus non-winners were similar in age and female winners were younger than the average age in their respective weight category. Male and female winners had a taller average height compared to male and female non-winners. The average BMI of male and female winners was less than non-winners. Females were eight times more likely to win by superiority than males. Overall, 100% of techniques used to score were by kicks. Specifically, males and females used one-point offensive and defensive kicks more than two-point offensive kicks to score. Males had more average kyong-go (half point warning) and gam-jeom (full point deduction) warning deductions per match versus females, thus demonstrating a more aggressive style of combat. In addition, males had a total of four knock downs during the entire competition, one in each weight category, whereas there were no knock downs among females, again suggesting a more aggressive fighting style among males.

    The GPM satellite has made it possible to observe the amount and nature of precipitation in remote areas of midlatitudes, including oceans and mountain ranges. OLYMPEX conducted over the Olympic Mountains on the northwest coast of Washington State was designed to provide the means for evaluating the physical basis of the algorithms used to convert GPM satellite measurements to determine the amount and nature of precipitation in midlatitude extratropical cyclones. Microphysical processes producing precipitation are highly sensitive to the vertical profile of temperature. In the tropics, the domain of the TRMM satellite, the temperature profile varies only slightly. GPM algorithms, however, must account for the strong horizontal variation of temperature profiles in baroclinic storms systems of midlatitudes and for the variations of precipitation mechanisms caused by passage of these storms over mountains. The OLYMPEX scientific strategy was: 1) collect a statistically robust set of measurements in midlatitude cyclones upstream of, over, and downstream of a midlatitude mountain range that can be used to improve GPM satellite algorithms; 2) determine how the physics and dynamics of the mechanisms affecting precipitation formation in relation to storm structure and terrain. To accomplish these goals 3 aircraft, 4 scanning dual polarization Doppler radars, supplemental soundings, and sophisticated surface instruments were deployed on the Olympic Peninsula of Washington, where Pacific frontal systems produce seasonal precipitation of 2000-4000 mm. 13 storms were observed. 3 of these were atmospheric rivers. The NASA DC-8 and ER-2 aircraft overflew the storms with instruments similar to those on GPM. The U. North Dakota Citation sampled hydrometeors in situ. Preliminary analysis indicates that one of the primary modes of orographic enhancement is low-level moist flow rising over the lower windward slopes and producing many very small drops.

  4. Unsteady Sail Dynamics in Olympic Class Sailboats

    Williamson, Charles; Schutt, Riley

    2016-11-01

    Unsteady sailing techniques have evolved in competitive sailboat fleets, in cases where the relative weight of the sailor is sufficient to impart unsteady motions to the boat and sails. We will discuss three types of motion that are used by athletes to propel their boats on an Olympic race course faster than using the wind alone. In all of our cases, body weight movements induce unsteady sail motion, increasing driving force and speed through the water. In this research, we explore the dynamics of an Olympic class Laser sailboat equipped with a GPS, IMU, wind sensor, and a 6-GoPro camera array. We shall briefly discuss "sail flicking", whereby the helmsman periodically rolls the sail into the apparent wind, at an angle which is distinct from classical heave (in our case, the oscillations are not normal to the apparent flow). We also demonstrate "roll tacking", where there are considerable advantages to rolling the boat during such a maneuver, especially in light wind. In both of the above examples from on-the-water studies, corresponding experiments using a towing tank exhibit increases in the driving force, associated with the formation of strong vortex pairs into the flow. Finally, we focus on a technique known as "S-curving" in the case where the boat sails downwind. In contrast to the previous cases, it is drag force rather than lift force that the sailor is trying to maximise as the boat follows a zig-zag trajectory. The augmented apparent wind strength due to the oscillatory sail motion, and the growth of strong synchronised low-pressure wake vortices on the low-pressure side of the sail, contribute to the increase in driving force, and velocity-made-good downwind.

    Lepton number is a fundamental symmetry that can be probed at the LHC. Here, we study the Higgs sector of theories responsible for neutrino mass generation. After a brief discussion of simple see-saw scenarios, we turn to theories where heavy Majorana neutrino mass is protected by a gauge symmetry and focus on the Left-Right symmetric theory. There, the SM-like Higgs boson can decay to a pair of heavy neutrinos and provide enough information to establish the origin of neutrino mass.

    The discovery of the Higgs boson at the Large Hadron Collider marks the culmination of a decades-long hunt for the last ingredient of the Standard Model. At the same time, there are still many puzzles in particle physics, foremost the existence of a relatively light Higgs boson, seemingly without any extra weak scale particles that would stabilize the Higgs mass against quantum corrections, and the existence of Dark Matter. This talk will give an overview of the most interesting theories that address these problems and how to test these theories at the LHC.

    We explore scenarios where top quarks may be produced singly in association with missing energy, a very distinctive signature, which, in analogy with monojets, we dub monotops. We find that monotops can be produced in a variety of modes, typically characterized by baryon number-violating or flavorchanging neutral interactions. We build a simplified model that encompasses all the possible (tree-level) production mechanisms and study the LHC sensitiveness to a few representative scenarios by considering fully hadronic top decays. We find that constraints on such exotic models can already be set with 1 fb{sup -1} of integrated luminosity collected at {radical}(s)=7 TeV.

    2008-08-01

    The introduction of insulin pens has helped improve adherence in Type 1 or 2 diabetes, and reduce inaccurate dosing, fear of injection, and social embarrassment associated with vial and syringe. This report presents the published evidence base for the accuracy, patient preference and economic evaluation of one prefilled pen, FlexPen (Novo Nordisk A/S, Bagsvaerd, Denmark) and discusses recent changes to the design of this pen. Primary research publications that included the study of FlexPen were identified from various sources. Several studies have shown that FlexPen delivers high, medium and low doses of insulin significantly more accurately than vial and syringe, SoloStar (sanofi-aventis, Paris, France) or OptiClik (sanofi-aventis, Paris, France). Patients have also found FlexPen easier to use than vial and syringe. A Next Generation FlexPen has been developed, which maintains the demonstrated accuracy of FlexPen and is accompanied by a reduced injection force for simpler and more comfortable use, and clear colour scheme for insulin type to avoid medication errors.

  12. LHC - a "Why" Facility

    2016-07-12

    The Standard Models of particle physics and cosmology describe the world we see, and how it works, very well. But we want to understand (not just accommodate) much more – how does the Higgs mechanism work, what is the dark matter, why is the universe matter and not antimatter, why is parity violated, why are the particles (quarks and leptons) what they are, and why are the forces that act on them to make our world what they are, and more. Today is an exciting time to be doing particle physics – on the experimental side we have data coming from LHC and dark matter experiments that will provide clues to these questions, and on the theoretical side we have a framework (string theory) that addresses all these “why” questions. LHC data will not qualitatively improve our description – rather, it may provide the data that will allow us to learn about the dark matter, the Higgs physics, the matter asymmetry, etc, to test underlying theories such as string theory, and begin to answer the “why” questions. Supersymmetry is the best motivated discovery, and it would also open a window to the underlying theory near the Planck scale.

  13. Supersymmetry at LHC

    SciTech Connect

    Bartl, A.; Soederqvist, J.; Paige, F.

    1996-11-22

    Supersymmetry (SUSY) is an appealing concept which provides a plausible solution to the fine tuning problem, while leaving the phenomenological success of the Standard Model (SM) unchanged. Moreover, some SUSY models allow for the unification of gauge couplings at a scale of M{sub GUT} {approx} 10{sup 16} GeV. A further attractive feature is the possibility of radiative breaking of the electro-weak symmetry group SU(2) {times} U(1). The masses of the SUSY partners of the SM particles are expected to be in the range 100 GeV to 1 TeV. One of the main goals of the Large Hadron Collider (LHC) will be either to discover weak-scale SUSY or to exclude it over the entire theoretically allowed parameter space. The authors have developed a strategy for the analysis of experimental data at LHC which will allow them to determine the scale for supersymmetry, to limit the model parameter space, and to make precision measurements of model parameters.

    2016-03-01

    We investigate the feasibility of cutting and drilling thin flex glass (TFG) substrates using a picosecond laser operating at wavelengths of 1030 nm, 515 nm and 343 nm. 50 μm and 100 μm thick AF32®Eco Thin Glass (Schott AG) sheets are used. The laser processing parameters such as the wavelength, pulse energy, pulse repetition frequency, scan speed and the number of laser passes which are necessary to perform through a cut or to drill a borehole in the TFG substrate are studied in detail. Our results show that the highest effective cutting speeds (220 mm/s for a 50 μm thick TFG substrate and 74 mm/s for a 100 μm thick TFG substrate) are obtained with the 1030 nm wavelength, whereas the 343 nm wavelength provides the best quality cuts. The 515 nm wavelength, meanwhile, can be used to provide relatively good laser cut quality with heat affected zones (HAZ) of <25 μm for 50 μm TFG and <40 μm for 100 μm TFG with cutting speeds of 100 mm/s and 28.5 mm/s, respectively. The 343 nm and 515 nm wavelengths can also be used for drilling micro-holes (with inlet diameters of ⩽75 μm) in the 100 μm TFG substrate with speeds of up to 2 holes per second (using 343 nm) and 8 holes per second (using 515 nm). Optical microscope and SEM images of the cuts and micro-holes are presented.

    To describe injury and illness incidence from the US Youth Olympic Team during the 2014 Youth Olympic Games (YOG). Electronic health records of Team USA athletes registered for the YOG were reviewed for patient encounters during the 2014 YOG. Medical encounters were defined as all medical services provided by a healthcare provider including evaluation, treatment and prophylactic services. All medical conditions were categorised by IOC Injury and Illness reporting criteria. Team USA was comprised of 48 male and 46 female athletes, aged of 14-18 years, representing 20 sports. There were 346 total medical encounters among 54 of the 94 registered athletes for a rate of 3.7 medical encounters per athlete. A total of 40 injuries were recorded (14 time loss injuries, 26 non-time loss) and 20 illnesses. This equates to 43% of athletes sustaining an injury, and 21% sustaining an illness, with a frequency of 426 injuries and 213 illnesses per 1000 registered athletes. The most commonly involved body regions for time loss injuries were the knee (21%) and ankle (12%). Time loss injuries most frequently occurred in competition (71%) and the most common type of injury was a ligament sprain (43%). The most common illnesses were respiratory (35%) and dermatological conditions (30%). The rates of injury, illness and medical encounters per athlete were greater than in previous reports of medical service provisions at youth Olympic-level sporting events.

    The objectives of this study were 1) to describe the technical requirements of different tracks where classifying points are disputed for the Olympics as the European continent tracks (E), world championship competitions tracks (W), and Olympic Games track - Beijing, 2008- (O); and 2) to compare and establish differences or similarities between the three previous contexts. The sample used for this study was made of the 8 best qualifying male athletes from each competition (n = 48) during the 2007 and 2008 seasons (pre-Olympic and Olympic years). A descriptive design was used, based on systematic structured observation of the competitions filmed on video, paying attention to the different techniques used (overtaking skills, complete pedalling cycles and registered effort times). The results show that aerial techniques predominate over non aerial techniques on O and W type tracks more than on E tracks by ~20% (p < 0.001), pedaling cycles predominate in E vs. W and O by 11.85 and 24.23% respectively (p ≤ 0.05), and effort times predominate in O vs. W and E by 6.50 and 12.94% respectively (p ≤ 0.01). In conclusion, O and W tracks stand out because of the aerial component and greater technical complexity in comparison to E tracks, which has a decisive effect on the way the riders train in relation to the type of championship they aim to compete in. Key pointsEuropean tracks involve more non aerial techniques than world and Olympic tracks, respectively; more non aerial techniques are associated with more pedaling effort time.Bicycle motocross cyclists develop greater values of aerial Techniques in World and Olympic tracks compared with the European tracks and, consequently, reduced non aerial techniques.European tracks involve less technical jumps but more simple jumps.

  16. The regeneration games: purity and security in the Olympic city.

    PubMed

    Fussey, Pete; Coaffee, Jon; Armstrong, Gary; Hobbs, Dick

    2012-06-01

    This paper examines the wider social impacts of hosting the London 2012 Olympic Games and its 'legacy' ambitions in East London, emphasizing securitization as an inbuilt feature of the urban regeneration project. Drawing on extensive original empirical research, the paper analyses the modalities of Olympic safety and security practices within the Olympic Park itself and their wider impact, while also connecting this research to theorization and debates in urban sociology and criminology. In this complex setting, a raft of formal and informal, often subtle, regulatory mechanisms have emerged, especially as visions of social ordering focused on 'cleansing' and 'purifying' have 'leaked out' from the hyper-securitized 'sterilized' environment of the Olympic Park and become embedded within the Olympic neighbourhood. In such complex circumstances, applying Douglas' (1966) work on purity and danger to the spatial realm provides a key conceptual framework to understand the form and impact of such processes. The imposition of order can be seen to not only perform 'cleansing' functions, but also articulate multiple symbolic, expressive and instrumental roles. © London School of Economics and Political Science 2012.

  17. Medical and Orthopaedic Conditions in Special Olympics Athletes

    PubMed Central

    2001-01-01

    Objective: Many Special Olympics athletes experience hypokinetic diseases and comorbid conditions that may predispose them to serious injuries during physical activity. A clear understanding of these conditions and diseases may assist health care professionals in preventing further distress and managing the injuries sustained by these athletes. Such diseases and conditions include overweight and obesity, diabetes, vision problems, seizure disorders, and Down syndrome, which is often associated with atlantoaxial instability. Data Sources: MEDLINE, SPORT Discus, and Special Olympics information sources for the years 1990–2000 using the key terms Special Olympics, mental retardation, comorbidity, Down syndrome, hypokinetic diseases, and physical activity were searched. Data Synthesis: A basic review of hypokinetic diseases and comorbid conditions prepares health care professionals for working with people with mental retardation. Conclusions and Recommendations: Health care volunteers at Special Olympics events treat athletes with mental retardation who may also have some of the comorbid conditions and hypokinetic diseases observed commonly in this population. Moreover, many of these conditions and diseases are typical in athletes without mental retardation. Athletic trainers should be familiar with these conditions and diseases but should review the unique conditions and prescription medications commonly found in the Special Olympics population before providing medical services for these athletes.

    Mass gatherings require attention toward planning and execution of dedicated medical care. The aims were to describe the organization and provision of medical care in the Torino 2006 Winter Olympic Games in light of the epidemiology of illnesses and injuries among athletes during this event. The organization integrated 18 medical centers operating at Olympic venues, three polyclinics inside the Olympic Villages, and 13 pre-existing Olympic Hospitals. The design was a retrospective study, with review of medical records at Olympic medical facilities. All the athletes who attended any medical center or polyclinic were eligible. The main outcomes included type of injuries and illnesses affecting athletes, incidence of injuries and illnesses by provenance and discipline, and rate of hospital admissions. A total of 330 athletes received medical care and 676 medical encounter forms were documented, with an overall medical utilization rate of 12.66%. Skeleton, snowboard, bobsleigh, and alpine and freestyle skiing had the highest medical attendance rate relative to other disciplines (p < 0.001). The majority of injuries and illnesses were of a minor nature. A total of 23 visits required hospital admissions (3.40%). The described model of medical coverage for such events seemed to be practical and efficient for the athletes, without depleting services to the general population. The risk of severe injury and illness seemed to be low. These data could be useful for planning medical services in future mass gatherings. Copyright © 2010 Elsevier Inc. All rights reserved.

  19. Urethane/Silicone Adhesives for Bonding Flexing Metal Parts

    NASA Technical Reports Server (NTRS)

    Edwards, Paul D.

    2004-01-01

    Adhesives that are blends of commercially available urethane and silicone adhesives have been found to be useful for bonding metal parts that flex somewhat during use. These urethane/silicone adhesives are formulated for the specific metal parts to be bonded. The bonds formed by these adhesives have peel and shear strengths greater than those of bonds formed by double-sided tapes and by other adhesives, including epoxies and neat silicones. In addition, unlike the bonds formed by epoxies, the bonds formed by these adhesives retain flexibility. In the initial application for which the urethane/silicone adhesives were devised, there was a need to bond spring rings, which provide longitudinal rigidity for inflatable satellite booms, with the blades that provide the booms axial strength. The problem was to make the bonds withstand the stresses, associated with differences in curvature between the bonded parts, that arose when the booms were deflated and the springs were compressed. In experiments using single adhesives (that is, not the urethane/ silicone blends), the bonds were broken and, in each experiment, it was found that the adhesive bonded well with either the ring or with the blade, but not both. After numerous experiments, the adhesive that bonded best with the rings and the adhesive that bonded best with the blades were identified. These adhesives were then blended and, as expected, the blend bonded well with both the rings and the blades. The two adhesives are Kalex (or equivalent) high-shear-strength urethane and Dow Corning 732 (or equivalent) silicone. The nominal mixture ratio is 5 volume parts of the urethane per 1 volume part of the silicone. Increasing the proportion of silicone makes the bond weaker but more flexible, and decreasing the proportion of silicone makes the bond stronger but more brittle. The urethane/silicone blend must be prepared and used quickly because of the limited working time of the urethane: The precursor of the urethane

  20. A 16-channel flex circuit for cryogenic microwave signal transmission

    NASA Astrophysics Data System (ADS)

    2014-07-01

    Heterodyne focal plane arrays used in the terahertz (THz) regime currently require a discrete set of rigid coaxial cables for the transmission of individual intermediate frequency (IF) signals. Consequently, the size of an array is limited to ~10s of pixels due to limited physical space and the complexity of assembly. In order to achieve an array with ~1000 pixels or greater, new interconnections must be developed capable of carrying multiple IF signals on a single carrier which is flexible, robust to noise, and terminated with a high density RF connector. As an intermediate step to the development of a ~1000 pixel heterodyne focal plane array, the Kilopixel Array Pathfinder Project (KAPPa) has developed a 16 channel IF flex circuit. Initially, design simulations were performed to evaluate various means of high-frequency (1~10 GHz) signal transmission, including microstrip, stripline and coplanar waveguides. The method allowing for the closest signal spacing and greatest resistance to radio frequency interference (RFI) was determined to be stripline. Designs were considered where stripline transitioned to microstrip in order to terminate the signal. As microstrip transmission lines are sensitive to RFI, a design featuring just stripline was evaluated. In both the stripline-to-microstrip and stripline-only designs, a three-layer copper-coated polyimide substrate was used. Signal transitions were accomplished by a signal carrying "hot" via passing through a series of three conductive pads, similar to work by Leib et al. (2010). The transition design essentially mimics a coaxial line, where the radial distance between the pads and the ground plane is optimized in order to achieve desired impedances. In simulation, 50 Ohm impedances were achieved throughout, with crosstalk and return loss limited to -30dB. Terminations are made via an array of Corning Gilbert G3PO blind mate connectors, which are small enough to match the 6mm pixel pitch of the KAPPa focal plane unit

  1. FlexAID: Revisiting Docking on Non-Native-Complex Structures.

    PubMed

    Gaudreault, Francis; Najmanovich, Rafael J

    2015-07-27

    Small-molecule protein docking is an essential tool in drug design and to understand molecular recognition. In the present work we introduce FlexAID, a small-molecule docking algorithm that accounts for target side-chain flexibility and utilizes a soft scoring function, i.e. one that is not highly dependent on specific geometric criteria, based on surface complementarity. The pairwise energy parameters were derived from a large dataset of true positive poses and negative decoys from the PDBbind database through an iterative process using Monte Carlo simulations. The prediction of binding poses is tested using the widely used Astex dataset as well as the HAP2 dataset, while performance in virtual screening is evaluated using a subset of the DUD dataset. We compare FlexAID to AutoDock Vina, FlexX, and rDock in an extensive number of scenarios to understand the strengths and limitations of the different programs as well as to reported results for Glide, GOLD, and DOCK6 where applicable. The most relevant among these scenarios is that of docking on flexible non-native-complex structures where as is the case in reality, the target conformation in the bound form is not known a priori. We demonstrate that FlexAID, unlike other programs, is robust against increasing structural variability. FlexAID obtains equivalent sampling success as GOLD and performs better than AutoDock Vina or FlexX in all scenarios against non-native-complex structures. FlexAID is better than rDock when there is at least one critical side-chain movement required upon ligand binding. In virtual screening, FlexAID results are lower on average than those of AutoDock Vina and rDock. The higher accuracy in flexible targets where critical movements are required, intuitive PyMOL-integrated graphical user interface and free source code as well as precompiled executables for Windows, Linux, and Mac OS make FlexAID a welcome addition to the arsenal of existing small-molecule protein docking methods.

  2. Gender verification of female Olympic athletes.

    PubMed

    Dickinson, Barry D; Genel, Myron; Robinowitz, Carolyn B; Turner, Patricia L; Woods, Gary L

    2002-10-01

    Gender verification of female athletes has long been criticized by geneticists, endocrinologists, and others in the medical community. Problems include invalid screening tests, failure to understand the problems of intersex, the discriminatory singling out of women based only on laboratory results, and the stigmatization and emotional trauma experienced by individuals screened positive. Genuine sex-impostors have not been uncovered by laboratory-based genetic testing; however, gender verification procedures have resulted in substantial harm to a number of women athletes born with relatively rare genetic abnormalities. Individuals with sex-related genetic abnormalities raised as females have no unfair physical advantage and should not be excluded or stigmatized, including those with 5-alpha-steroid-reductase deficiency, partial or complete androgen insensitivity, and chromosomal mosaicism. In 1990, the International Amateur Athletics Federation (IAAF) called for ending genetic screening of female athletes and in 1992 adopted an approach designed to prevent only male impostors from competing. The IAAF recommended that the "medical delegate" have the ultimate authority in all medical matters, including the authority to arrange for the determination of the gender of the competitor if that approach is judged necessary. The new policy advocated by the IAAF, and conditionally adopted by the International Olympic Committee, protects the rights and privacy of athletes while safeguarding fairness of competition, and the American Medical Association recommends that it become the permanent approach.

  3. Sequential effects in Olympic synchronized diving scores

    PubMed Central

    2017-01-01

    When judging performances in a sequence, the current score is often influenced by the preceding score. Where athletes are perceived to be similar, a judgement is assimilated towards the previous one. However, if judges focus on the differences between the two athletes, this will result in a contrasting influence on their scores. Here, I investigate sequential effects during synchronized diving events at the 2012 and 2016 Olympic Games. Although previous research found assimilation in scores of gymnasts, the current data showed contrast effects—current scores benefited from following a poor performance but were at a disadvantage if they followed a high-scoring performance. One explanation may be that the processes involved in judging synchronized pairs results in a focus on the differences between athletes, producing a contrast effect across dives. That the specific direction of this sequential bias may depend on the particular sport has implications for how judges might approach their roles in a context-dependent manner, as well as how such biases should be addressed.

    Major, rare and complex incidents can occur at any mass-gathering sporting event and team medical staff should be appropriately prepared for these. One such event, the Athens Olympic Games in 2004, presented a significant sporting and medical challenge. This study concerns an epidemiological analysis of foot and ankle injuries during the Games. An observational, epidemiological survey was used to analyse injuries in all sport tournaments (men's and women's) over the period of the Games. A total of 624 injuries (525 soft tissue injuries and 99 bony injuries) were reported. The most frequent diagnoses were contusions, sprains, fractures, dislocations and lacerations. Significantly more injuries in male (58%) versus female athletes (42%) were recorded. The incidence, diagnosis and cause of injuries differed substantially between the team sports. Our experience from the Athens Olympic Games will inform the development of public health surveillance systems for future Olympic Games, as well as other similar mass events.

    We analyze the potential of the Large Hadron Collider (LHC) to observe signatures of phenomenologically viable walking technicolor models. We study and compare the Drell-Yan and vector boson fusion mechanisms for the production of composite heavy vectors. We find that the heavy vectors are most easily produced and detected via the Drell-Yan processes. The composite Higgs phenomenology is also studied. If technicolor walks at the LHC, its footprints will be visible and our analysis will help in uncovering them.

    The REM star C-Flex (Fa. Respironics) was introduced in 2003. In contrast to the conventionel fix CPAP mode, the C-Flex mode is characterised by a pressure reduction at the beginning of expiration. In a randomised cross-over design, we investigated if this C-Flex-mode has advantages compared to the fix CPAP mode in terms of treatment quality and patient satisfaction. In this prospective randomised single-blinded cross-over study we investigated 20 patients with obstructive sleep apnoea treated with fix CPAP versus treatment with the C-Flex mode (level 2) for 6 weeks, respectively. We compared the polysomnographically measured quality of treatment and the subjective satisfaction of either form of therapy. Additionally, we measured long-term compliance of the C-Flex therapy in a 3-year follow-up with the integrated counter of the C-Flex devices. The mean levels of pressure of the fix CPAP and the C-Flex therapies were 8.4 +/- 2.9 mbar in both groups. There was an identical quality of treatment in terms of respiratory events, arousal index, slow wave sleep and Epworth sleepiness scale. The compliance of nocturnal use of the C-Flex and the fix CPAP was identical (6.0 +/- 0.67 C-Flex use vs. 5.8 +/- 0.98 CPAP use [h/night]). The subjective satisfaction was higher in the C-Flex mode at the end of the study since 18 of 20 patients (90%) subjectively prefered the C-Flex mode because of the easier expiration. 19 patients received a C-Flex device for long-term therapy. The 3-year-follow-up showed a regular utilisation of the C-Flex by 16 of 19 (84.2%) of these patients (mean nocturnal use 6.0 +/- 0.9 h/night). 3 of the 19 patients (15.8%) did not use their C-Flex regulary. None of the patients has terminated therapy completely. C-Flex mode and the conventional fix CPAP therapies show an equivalent treatment quality according to polysomnographic data. The expiratory pressure reduction compared to conventional CPAP was felt to be more comfortable by 90% of patients. The long

    The High Luminosity LHC is one of the major scientific project of the next decade. It aims at increasing the luminosity reach of LHC by a factor five for peak luminosity and a factor ten in integrated luminosity. The project, now fully approved and funded, will be finished in ten years and will prolong the life of LHC until 2035-2040. It implies deep modifications of the LHC for about 1.2 km around the high luminosity insertions of ATLAS and CMS and relies on new cutting edge technologies. We are developing new advanced superconducting magnets capable of reaching 12 T field; superconducting RF crab cavities capable to rotate the beams with great accuracy; 100 kA and hundred meter long superconducting links for removing the power converter out of the tunnel; new collimator concepts, etc... Beside the important physics goals, the High Luminosity LHC project is an ideal test bed for new technologies for the next hadron collider for the post-LHC era.

    The purpose of the Olympic Games should be to contribute to the social development by leaving behind economic, cultural and environmental legacies to the hosting region. While tangible examples such as venues are often recognized as representative legacies of the Olympics, intangible aspects such as the environment, culture, policy and human resources have been gaining in importance. The Olympic Games, at its most fundamental level, is a sporting event. Sports not only is closely related to the physical health, but is also instrumental to fostering mental health through inspiration. One of the most important sports legacies was the general change in the population’s perception on sports and physical activities; due to such change, people were able to enjoy sports as part of healthy and active everyday life and benefit physically.

    The purpose of the Olympic Games should be to contribute to the social development by leaving behind economic, cultural and environmental legacies to the hosting region. While tangible examples such as venues are often recognized as representative legacies of the Olympics, intangible aspects such as the environment, culture, policy and human resources have been gaining in importance.

    The aim of this study was to develop an instrument for evaluating how an education program has been implemented. Such evaluation can provide insight into the effectiveness of a program. Examined here was the Olympic Education Program used in Greek schools since 2000. In it, students learn the history of the Olympic games and the importance of exercise for health along with the principles and values of sports and volunteerism. The evaluation instrument underlying this study addressed the following six factors: `facilities', `administration', `educational material', `student-teacher relationships', `educational procedures', and `training'. Results indicate that the instrument, while adequate for assessing effectiveness, should be combined with advanced statistical methods.

  12. Prehistoric rock avalanches in the Olympic Mountains, Washington

    Rock avalanches blocked streams in the Olympic Mountains southwest of Puget Sound during the past few thousand years. Limiting radiocarbon ages indicated that three or four of six avalanches occurred from 1000 to 1300 years ago or shortly thereafter. Most of the dates were from the outer preserved rings of trees drowned behind avalanche dams. These three or four avalanches may be coeval not only with one another but also with abrupt tectonic deformation in western Washington. No rock avalanches in the Olympic Mountains are known to have resulted from storms or earthquakes during the past century. The avalanches strengthen the case that a large prehistoric earthquake occurred in the Puget Sound region.

  13. Self-shielding flex-circuit drift tube, drift tube assembly and method of making

    DOEpatents

    Jones, David Alexander

    2016-04-26

    The present disclosure is directed to an ion mobility drift tube fabricated using flex-circuit technology in which every other drift electrode is on a different layer of the flex-circuit and each drift electrode partially overlaps the adjacent electrodes on the other layer. This results in a self-shielding effect where the drift electrodes themselves shield the interior of the drift tube from unwanted electro-magnetic noise. In addition, this drift tube can be manufactured with an integral flex-heater for temperature control. This design will significantly improve the noise immunity, size, weight, and power requirements of hand-held ion mobility systems such as those used for explosive detection.

    A plurality of flexible cylindrical members, termed flex-gears and having gear tooth type perimeters are located in an annular space between two concentric rotating gear members, one an inner gear member and the other an outer ring gear member, both of which have mutually facing toothed surfaces which engage the flex-gears. The flex-gears rotate and orbit around the annular space as planetary gears when the inner and outer gear members rotate with respect to one another. Pairs of these elements located in two mutually parallel planes and separated by insulators provide two electrical conductor paths across which an electrical signal source, AC or DC, can be connected and coupled to an electrical device. Alternatively, one set of elements including outer gears segmented into mutually insulated semicircles and inner gears segmented into mutually insulated quadrants can be used.

    We design a search strategy for the Standard Model t t bar t t bar production at the LHC in the same-sign dilepton and trilepton channels. We study different signal features and, given the small expected number of signal events, we scrutinize in detail all reducible and irreducible backgrounds. Our analysis shows that by imposing a basic set of jet and lepton selection criteria, the SM pp → t t bar t t bar process could be evidenced in the near future, within Run-II, when combining both multi-lepton search channels. We argue that this search strategy should also be used as a guideline to test New Physics coupling predominantly to top-quarks. In particular, we show that a non-resonant New Physics enhancement in the four-top final state would be detectable through this search strategy. We study two top-philic simplified models of this kind, a neutral scalar boson and a Z‧, and present current and future exclusion limits on their mass and couplings.

    The Flame Extinguishment Experiment (FLEX) program is a continuing set of experiments on droplet combustion, performed employing the Multi-User Droplet Combustion Apparatus (MDCA), inside the chamber of the Combustion Integrated Rack (CIR), which is located in the Destiny module of the International Space Station (ISS). This report describes the experimental hardware, the diagnostic equipment, the experimental procedures, and the methods of data analysis for FLEX. It also presents the results of the first 284 tests performed. The intent is not to interpret the experimental results but rather to make them available to the entire scientific community for possible future interpretations.

    2008-01-01

    The pFlexAna (protein flexibility analyzer) web server detects and displays conformational changes in remotely related proteins, without relying on sequence homology. To do so, it first applies a reliable statistical test to align core protein fragments that are structurally similar and then clusters these aligned fragment pairs into ‘super-alignments’, according to the similarity of geometric transformations that align them. The result is that the dominant conformational changes occur between the clusters, while the smaller conformational changes occur within a cluster. pFlexAna is available at http://bigbird.comp.nus.edu.sg/pfa2/.

    1991-01-01

    An order (n) multiflex body Space Station simulation tool is introduced. The flex multibody modeling is generic enough to model all phases of Space Station from build up through to Assembly Complete configuration and beyond. Multibody subsystems such as the Mobile Servicing System (MSS) undergoing a prescribed translation and rotation are also allowed. The software includes aerodynamic, gravity gradient, and magnetic field models. User defined controllers can be discrete or continuous. Extensive preprocessing of 'body by body' NASTRAN flex data is built in. A significant aspect, too, is the integrated controls design capability which includes model reduction and analytic linearization.

    Offering employment structures other than traditional full-time positions in your practice can help you draw excellent job applicants and also can enable you to increase morale, job satisfaction, and productivity. However, there are many decisions you must make when offering a part-time, flex-time, or job-sharing position. This article explores the pros and cons of offering alternative job structures. It suggests ways to make part-time, flex-time, or job-sharing positions work most effectively, both for the employee and for your practice. In addition, this article suggests which positions are best suited to alternative structures.

  1. An object simulation model for modeling hypothetical disease epidemics – EpiFlex

    PubMed Central

    Hanley, Brian

    2006-01-01

    Background EpiFlex is a flexible, easy to use computer model for a single computer, intended to be operated by one user who need not be an expert. Its purpose is to study in-silico the epidemic behavior of a wide variety of diseases, both known and theoretical, by simulating their spread at the level of individuals contracting and infecting others. To understand the system fully, this paper must be read together in conjunction with study of the software and its results. EpiFlex is evaluated using results from modeling influenza A epidemics and comparing them with a variety of field data sources and other types of modeling. EpiFlex is an object-oriented Monte Carlo system, allocating entities to correspond to individuals, disease vectors, diseases, and the locations that hosts may inhabit. EpiFlex defines eight different contact types available for a disease. Contacts occur inside locations within the model. Populations are composed of demographic groups, each of which has a cycle of movement between locations. Within locations, superspreading is defined by skewing of contact distributions. Results EpiFlex indicates three phenomena of interest for public health: (1) R0 is variable, and the smaller the population, the larger the infected fraction within that population will be; (2) significant compression/synchronization between cities by a factor of roughly 2 occurs between the early incubation phase of a multi-city epidemic and the major manifestation phase; (3) if better true morbidity data were available, more asymptomatic hosts would be seen to spread disease than we currently believe is the case for influenza. These results suggest that field research to study such phenomena, while expensive, should be worthwhile. Conclusion Since EpiFlex shows all stages of disease progression, detailed insight into the progress of epidemics is possible. EpiFlex shows the characteristic multimodality and apparently random variation characteristic of real world data, but does

  2. Coping skills of olympic developmental soccer athletes.

    2008-12-01

    Athletes at Olympic Developmental Program (ODP) camps experience unusually high levels of expectations and inherent mental and physical challenges within such a short span of time. With the increasing emphasis on talent development, there has been consensus by the ODP staff to more clearly define present levels of coping skills, in order to enhance athletic prediction, maximize training efforts, identify the predisposition to injury, and focus on areas pertinent to successful performance. This study examined athletic and pain coping skills of U. S. ODP soccer athletes not previously investigated. Following written informed consent, 70 males completed the Athletic Coping Skills Inventory and the Sports Inventory for Pain. Data were analyzed by competitive level (U-14, U-15), and skill position (goalkeeper/defense, midfield/foward). MANOVA indicated a significant main effect across competitive level (Wilks' Lambda F(12,57) = 2.27; p = 0.02; n-beta = 0.915) but no significant effect by skill position (Wilks' Lambda F(12,57) = 0.931; p = 0.523; n-beta = 0.457). Post hoc analyses indicated that U-15 athletes scored significantly higher in concentration (p = 0.01) and body awareness (p = 0.03), but lower in avoidance (p = 0.01) than U-14 competitors. In conclusion, older, more experienced athletes revealed more positive athletic and pain coping skills than younger, less experienced athletes, although athletes in skill positions requiring spontaneous decision-making skills and split-second adjustment in a constantly changing sport environment (forwards, midfielders) did not exhibit more positive athletic and pain coping skills than those positions requiring reaction and protection (defenders, goalkeepers).

  3. Erythropoietin concentrations and isoforms in urine of anonymous Olympic athletes during the Nagano Olympic Games.

    The ordinary doping control urine samples of 36 anonymous participants (cross-country skiers, biathlon athletes, and curling athletes) of the 1998 Nagano Olympic Games were analyzed for erythropoietin and erythropoietin isoforms. The urine erythropoietin concentration (IU/l) was determined with a competitive radioimmunoassay method and the isoforms were studied by electrophoresis and given as milli albumin mobility units (mAMU). Erythropoietin was detectable in 23 out of 36 specimens (64%). The biathlon and curling athletes had similar urine concentration of erythropoietin. The group of 16 cross-country skiers had significantly (P < 0.05) increased urine concentration of erythropoietin as compared to curling athletes and four of them had urine erythropoietin concentrations between 3.6 and 5.1 IU/l. The electrophoretic mobility of erythropoietin was determined in all eight samples with urine concentration of erythropoietin of more than 2 (range 2.1-5.1) IU/l. No single urine specimen with a median erythropoietin electrophoretic mobility below the cut-off level of 670 mAMU (indicative of doping with recombinant erythropoietin) was registered. Erythropoietin in urine was detected in 71% and the isoforms of Epo characterized in 29% of the anonymous Olympic endurance athletes. The urine concentration of erythropoietin in the biathlon and curling athletes were similar to those of non-athletes. The group of cross-country skiers had higher levels of erythropoietin in urine. These higher levels of urine erythropoietin in cross-country skiers are partly due to more concentrated urine specimens.

    2013-02-01

    We present the first determination of parton distributions of the nucleon at NLO and NNLO based on a global data set which includes LHC data: NNPDF2.3. Our data set includes, besides the deep inelastic, Drell-Yan, gauge boson production and jet data already used in previous global PDF determinations, all the relevant LHC data for which experimental systematic uncertainties are currently available: ATLAS and LHCb W and Z rapidity distributions from the 2010 run, CMS W electron asymmetry data from the 2011 run, and ATLAS inclusive jet cross-sections from the 2010 run. We introduce an improved implementation of the FastKernel method which allows us to fit to this extended data set, and also to adopt a more effective minimization methodology. We present the NNPDF2.3 PDF sets, and compare them to the NNPDF2.1 sets to assess the impact of the LHC data. We find that all the LHC data are broadly consistent with each other and with all the older data sets included in the fit. We present predictions for various standard candle cross-sections, and compare them to those obtained previously using NNPDF2.1, and specifically discuss the impact of ATLAS electroweak data on the determination of the strangeness fraction of the proton. We also present collider PDF sets, constructed using only data from HERA, the Tevatron and the LHC, but find that this data set is neither precise nor complete enough for a competitive PDF determination.

    2003-12-01

    Since 1961, Special Olympics has provided sports training and athletic competition for people with mental retardation. A recent addition to these Olympics has been the Healthy Athletes Program, designed to help the athletes improve their health and fitness, leading to enhanced sports experiences and well being. Original health services included dental and eye screening. In 2002, Special Olympics Delaware piloted a Wellness Park to add nutrition, blood pressure, and flexibility screening. Faculty from a university's health college trained discipline-specific students to conduct the screenings. Thirty nutrition and dietetics students measured height, weight, waist circumference, and calculated body mass index (BMI) for the athletes. Figures and risk-assessments were recorded on a "health report card." Two hundred ten athletes attended the nutrition screening. Ages ranged from 8 to 63 years; 81 percent males and 19 percent females. According to BMI standards, 32 percent of the athletes were overweight; 17 percent were obese. Twenty-five percent of adult males and 73 percent of adult females had a high risk waist circumference. Athletes at high risk for obesity-related diseases were referred to their primary physician for follow up. Nutrition education handouts included a simplified Food Guide Pyramid, tips for healthy eating in restaurants, 5 A Day information, and healthful hydration guides. Approximately 1,250 athletes participate in Special Olympics Delaware each year, providing a great opportunity to do some much needed health screening and improve access to health care for this often neglected population.

    Context: Certified athletic trainers (ATs) are often the first health care providers to treat injured athletes. However, few researchers have studied ATs' beliefs concerning working with Special Olympics athletes. Objectives: To examine ATs' beliefs toward working with Special Olympics athletes by using the theory of planned behavior model and to examine the influence of moderator variables. Design: Cross-sectional survey. Setting: Athletic Trainers' Beliefs Toward Special Olympics Athletes survey instruments were mailed to 147 directors of Commission on Accreditation of Allied Health Education Programs–accredited athletic training education programs (ATEPDs) in 43 states and 120 cities. Patients or Other Participants: One hundred twenty ATEPDs (44 women, 76 men). Main Outcome Measure(s): We used stepwise multiple regression analysis to determine whether attitude toward the behavior, subjective norm, and perceived behavioral control predicted intention and to determine which moderator variables predicted attitude toward the behavior, subjective norm, and perceived behavioral control. Pearson product moment correlations were used to determine ATEPDs' beliefs about how competent they felt working with Special Olympics athletes and whether they were currently working with these athletes. Results: We found that subjective norm, attitude toward the behavior, and perceived behavioral control predicted intention (R  =  0.697, R2  =  0.486, F3,112  =  35.3, P < .001) and that intention predicted ATEPDs' actual behaviors (R  =  0.503, R2  =  0.253, F1,118  =  39.995, P < .001). Moderator variables that predicted attitude toward the behavior included more years of experience working with Special Olympics athletes, completion of 1 or more courses in adapted physical activity, ATEPDs' competence, completion of 1 or more special education courses, and sex (R  =  0.589, R2  =  0.347, F5,111  =  11.780, P < .001).

    Systematic analysis of integral aspects within sport enables improvement in performance. One key aspect is the management and prevention of injuries. Bibliometrics is a systematic method for evaluating research output. It may be expected that the quantity and quality of sports injury research over time may strongly correlate with the timing of the Olympic games. This study was conducted to determine the effect of the Olympic legacy on academic sports medicine and evidence to prevent injuries of the face and teeth. A literature search within the PubMed database was undertaken to identify the quantity of literature published annually between 1996 and 2015 in the fields of sports injuries and injury prevention. The top 5 journals publishing in each field were then identified and the change in their impact factor (IF) was investigated. It was seen that, since 1996, there has been an overall increase in the quantity of literature published regarding sports injuries and prevention of sports injuries of 209% and 217%, respectively. Publications regarding facial injuries and dental injuries within sport show an increase of 114% and 71%, respectively. There was an increase in IF since 2000 in almost every journal investigated. A strong, positive correlation is seen among journals publishing on the prevention of sports injuries, showing a median IF increase of 2.8198. No statistical significance was found between Olympic years and the number of publications. Hence, there has been a gradual increase in both the quality and quantity of publications regarding sports injuries since 1996. However, there appears to be no immediate added effect of the "Olympic legacy" following each Olympic games on the quantity or quality of publications in these fields.

    The convenience and accuracy of insulin pens have led to their extensive use in patients with diabetes. Although all insulin pens go through extensive testing as part of the regulatory process, it is important that both the patient and clinician can be assured of the accuracy of the dose delivered. This study compared the dosing accuracy of two commonly available insulin pens, the SoloSTAR (sanofi-aventis Deutschland GmbH, Frankfurt, Germany) and FlexPen (Novo Nordisk A/S, Bagsvaerd, Denmark) devices. Doses of 5, 10, and 30 units of insulin were investigated for SoloSTAR and FlexPen, and specific units of accuracy were based on International Organization of Standards for insulin injection pens (+/-1 unit for the 5 and 10-unit doses, +/-5% for the 30-unit dose). A total of 30 pens were tested for both the SoloSTAR and FlexPen, and a total of 2,280 measurement values were taken for each pen type (5 units, 1,260; 10 units, 750; and 30 units, 270 doses). Both devices were shown to be accurate at all three doses, and all doses were delivered within the limits proposed by the International Standard of Organization, which is used as part of the regulatory approval process when introducing an insulin injection device to the market. Our study shows that the SoloSTAR and FlexPen devices have comparable accuracy.

    We report on recent calculations of low missing mass single (SD) and double (DD) diffractive dissociation at LHC energies. The calculations are based on a dual-Regge model, dominated by a single Pomeron exchange. The diffractively excited states lie on the nucleon trajectory N*, appended by the isolated Roper resonance. Detailed predictions for the squared momentum transfer and missing mass dependence of the differential and integrated single-and double diffraction dissociation in the kinematical range of present and future LHC measurements are given.

  12. Reposition sense of lumbar curvature with flexed and asymmetric lifting postures.

    PubMed

    Wilson, Sara E; Granata, Kevin P

    2003-03-01

    Reposition sense of lumbar curvature was assessed as a function of trunk flexion, trunk asymmetry, and target lumbar curvature using a repeated-measures design and an active-active proprioception paradigm. The objectives of the research were to measure the ability of the subjects to sense and control the lumbar curvature in different lifting postures and to see if error in the lumbar curvature would increase in high-risk postures. The risk of low back disorders (LBDs) is related to trunk posture, with greater risk reported in flexed and asymmetric trunk positions. Spinal posture, including trunk position and lumbar lordosis, influences spinal stability. Hence, the ability to accurately sense and control spinal curvature may be an important factor in the control of LBD risk. Eleven subjects were trained to assume specified lumbar curvatures using visual feedback. The ability of the subjects to reproduce this curvature without feedback was then assessed. This procedure was repeated for different trunk postures, including flexion and asymmetry, and with different target lumbar curvatures. These measurements demonstrated reposition error was increased in flexed trunk positions but was unchanged with trunk asymmetry. This increase in reposition error with flexion was diminished when the target posture and lumbar curvature were highly flexed and kyphotic. This research suggests that it may be difficult to control spinal curvature in flexed positions, leading to an increased risk of injury. For jobs in which flexed working postures are unavoidable, therefore, it is important to minimize potentially unstable events such as slipping or shifting loads to avoid injury.

  13. Open-source modular solutions for flexural isostasy: gFlex v1.0

    2015-06-01

    Isostasy is one of the oldest and most widely applied concepts in the geosciences, but the geoscientific community lacks a coherent, easy-to-use tool to simulate flexure of a realistic (i.e. laterally heterogeneous) lithosphere under an arbitrary set of surface loads. Such a model is needed for studies of mountain-building, sedimentary basin formation, glaciation, sea-level change, and other tectonic, geodynamic, and surface processes. Here I present gFlex, an open-source model that can produce analytical and finite difference solutions for lithospheric flexure in one (profile) and two (map view) dimensions. To simulate the flexural isostatic response to an imposed load, it can be used by itself or within GRASS GIS for better integration with field data. gFlex is also a component with the Community Surface Dynamics Modeling System (CSDMS) and Landlab modeling frameworks for coupling with a wide range of Earth-surface-related models, and can be coupled to additional models within Python scripts. As an example of this in-script coupling, I simulate the effects of spatially variable lithospheric thickness on a modeled Iceland ice cap. Finite difference solutions in gFlex can use any of five types of boundary conditions: 0-displacement, 0-slope (i.e. clamped); 0-slope, 0-shear; 0-moment, 0-shear (i.e. broken plate); mirror symmetry; and periodic. Typical calculations with gFlex require ≪ 1s to ~1 min on a personal laptop computer. These characteristics - multiple ways to run the model, multiple solution methods, multiple boundary conditions, and short compute time - make gFlex an effective tool for flexural isostatic modeling across the geosciences.

    Public expenditure on mega-events such as the London 2012 Olympic Games is often justified by the potential legacy of urban regeneration and its associated health and wellbeing benefits for local communities. The ORiEL (Olympic Regeneration in East London) study examined whether urban regeneration associated with the 2012 Games was associated with improved mental health. Adolescents aged 11-12 years attending schools in the Olympic host London Borough of Newham or in three adjacent comparison London Boroughs, completed a survey prior to the Olympic Games (2012) and six-months and 18-months after the Games (2013 and 2014, respectively). Change in depressive symptoms and wellbeing between baseline and each follow-up were examined. 2254 adolescents from 25 randomly selected schools participated. Adolescents from the Olympic host borough were more likely to have 'remained depressed' between baseline and the six-month and 18-month follow-ups (Relative Risk = 1.78, 95%CI 1.12-2.83; Relative Risk = 1.93, 95%CI 1.01-3.70), compared with adolescents from the comparison boroughs. No differences in wellbeing were observed. There was very little evidence that urban regeneration had any positive influence on adolescent mental health and some suggestion regeneration may have been associated with maintenance of depressive symptoms. Such programmes may have limited short-term impact on the mental health of adolescents. © The Author 2017.

    2004-04-01

    Coaches believe world-ranking lists are a reliable tool for predicting international swimming performance. To examine the relationship between world-ranking and Olympic performance, we modelled world-ranking time and best time from the 2000 Olympic Games for 407 top-50 world-ranked swimmers. Analysis of log-transformed times yielded within-athlete and between-athlete coefficients of variation (CV) and percent changes in performance from world-rankings to Olympics. Variations and performance progressions were compared across sex, stroke, distance, nation and medal status. The within-athlete coefficient of variation of performance for all swimmers was 0.8% (95% confidence limits: 0.7 to 0.9%). Females were slightly less consistent, although not substantially different to males (ratio of female/male within-athlete CV: 1.1; 95% confidence limits: 1.0 to 1.2) and had a wider range of talent (ratio of female/male between-athlete CV: 1.2; 95% confidence limits: 1.1 to 1.4). Swimmers from Australia (AUS) were more consistent than those from the United States (USA) and other nations (OTHER) (ratio of within-athlete CV, USA/AUS: 1.5; 95% confidence limits: 1.0 to 2.2; OTHER/ AUS: 1.6; 95% confidence limits: 1.2 to 2.1). Most Olympic medallists (87%) had a top-10 world-ranking. Overall performance time at the Olympics was slower than world-ranking time by 0.3% (95% confidence limits: 0.2 to 0.4%), medallists improved by 0.6% (95% confidence limits: 0.4 to 0.9%) and non-medallists swam 0.6% slower (95% confidence limits: 0.5 to 0.7%). We conclude that a top-10 ranked swimmer who can improve performance time by 0.6%, equivalent to 0.13 s in the men's 50-m freestyle, will substantially increase their chance of an Olympic medal (the difference between first and fourth place).

    The purpose of this study was to compare pen device-naïve patients' preferences for Humalog KwikPen (insulin lispro injection) (Eli Lilly and Company, Indianapolis, IN) to use of a vial and syringe and FlexPen(R) (insulin aspart injection) (Novo Nordisk A/S, Bagsvaerd, Denmark). This open-label, randomized, crossover 1-day study tested the hypotheses that KwikPen was preferred to vial and syringe, and if this was found to be a significant preference, that KwikPen was preferred to FlexPen. Accuracy of doses prepared, ease of use via insulin device assessment battery, and preference via insulin device preference battery were administered following each pen evaluation, and a final preference question administered following the evaluation of both pens. Clinical measures were not included as subjects injected into an appliance to simulate the injection experience. Primary outcome variables were evaluated by Question 13 of the insulin device preference battery and the final preference question. Among 232 enrolled patients randomized to 1 of 4 sequences (n = 58), Humalog KwikPen was significantly preferred over vial and syringe and over FlexPen. After patients were asked to assess Humalog KwikPen or FlexPen versus V&S by choosing "strongly agreed" or "agreed" to the following attributes: easy to use, easy to hold in their hands when injecting, and easy to press the injection button, the results exhibited significant differences in patient responses. Humalog KwikPen was significantly more accurate and was preferred to vial and syringe in appearance, quality, discretion, convenience, public use, easy to learn, easy to use, reliability, dose confidence, following insulin regimen, overall satisfaction, and recommendation to others. Humalog KwikPen was significantly preferred over vial and syringe and FlexPen. When compared with vial and syringe, Humalog KwikPen and FlexPen were easier to use and operate, demonstrated superior accuracy of doses prepared, and preferred by pen

    2006-12-01

    Seven highly trained male triathletes, aged 18 to 35 years, were tested during two simulated Olympic distance triathlons to determine whether run performance was enhanced when consuming 177 ml of water at 8, 16, 24, and 32 kilometers (Early Trials) compared to consumption at 10, 20, 30, and 40 kilometers (Late Trials), during the cycling segment of the triathlon. Swim times for 1500 m were similar between trials; 40-km cycling times were approximately 10 s faster during the Late Trials; however, 10-km run times were faster during the Early Trials (P < 0.02). No significant differences between run trials were found for the rating of perceived exertion, oxygen uptake, heart rate, and change in urine specific gravity. It was concluded that the consumption of fluids earlier in the cycle phase of the Olympic distance triathlon benefits the run and overall performance time.

    2009-01-01

    Spectators of the Olympic Games can enjoy a wide variety of sports, including strength, team, timed, endurance, and artistic sports. In the Olympic program, there are two synchronized events: synchronized diving and synchronized swimming. The precision of the synchronization of the athlete's movements and skills is an added feature of entertainment. Synchronized athletes have additional training requirements to perfect the synchronization of their skills. The physical demands on the athlete from the repetition of training required for the perfection of synchronization result in injuries unique to these sports. Although both traumatic and overuse injuries occur, overuse injuries are more common. As these disciplines are artistic, judged sports, these athletes also are susceptible to eating disorders and the female athlete triad. This article reviews the training regimen of these athletes and outlines the injuries and health concerns that are common in the synchronized sports.

    The start of a new Olympic cycle offers a fresh chance for individuals and nations to excel at the highest level in sport. Most countries attempt to develop systematic structures to identify gifted athletes and to promote their development in a certain sport. However, forecasting years in advance the next generation of sporting experts and stimulating their development remains problematic. In this article, we discuss issues related to the identification and preparation of Olympic athletes. We provide field-based data suggesting that an earlier onset and a higher volume of discipline-specific training and competition, and an extended involvement in institutional talent promotion programmes, during adolescence need not necessarily be associated with greater success in senior international elite sport. Next, we consider some of the promising methods that have been (recently) presented in the literature and applied in the field. Finally, implications for talent identification and promotion and directions for future research are highlighted.

    Better understanding of the incidence, mechanisms, and characteristics of potential injuries in wrestling helps to implement preventive measures to better care for these athletes. Several studies have investigated the incidence and type of injuries in amateur and intercollegiate wrestling; however, there is a lack of studies that review the incidence and nature of injuries in elite wrestlers during Olympic Games or World Championships. The purpose of this study was to assess the injury profile of elite senior wrestlers in Greco-Roman, freestyle, and female wrestling during the 2008 Beijing Olympic Games. Descriptive epidemiologic study. Study participants consisted of 343 wrestlers participating in the 2008 Beijing Olympic Games. Standard checkoff forms were used to collect the injury data, including injury type, severity, location, timing, and mechanism. A total of 343 athletes sustained 32 injuries during 406 matches, which is equivalent to an overall incidence of 9.30 injuries per 100 athletes and 7.88 injuries per 100 matches. Among the 3 styles, freestyle had the highest injury rate (10.1%) and female wrestling the lowest (7.5%). In sum, 84.4% of all injuries were categorized as mild. Although the overall injury rate in male athletes was slightly higher than that among female athletes (9.7% versus 7.5%), this difference was not statistically significant (odds ratio = 1.21, 95% confidence interval = 0.46-3.68; P = .40). The rate and severity of wrestling injuries during the 2008 Beijing Olympic Games were lower than previous reports. No serious and catastrophic injury was recorded, and most injuries were minor.

    Estimates of progression and variability of athletic performance in competitions are useful for researchers and practitioners interested in factors that affect performance. We used repeated-measures mixed modelling to analyse 676 official race times of 26 US and 25 Australian Olympic swimmers in the 12-month period leading up to the 2000 Olympic Games. Progression was expressed as percent changes in mean performance; variability was expressed as the coefficient of variation in performance of an individual swimmer between races. Within competitions, both nations showed similar improvements in mean time from heats through finals (overall 1.2%; 95% confidence limits 1.1 to 1.3%). Mean competition time also improved over 12 months by a similar amount in both nations (0.9%; 95% confidence limits 0.6 to 1.2%). The US swimmers showed a greater improvement between the finals (a difference of 0.5%; 95% confidence limits -0.2 to 1.1%), which paralleled changes in the medal haul of the two nations. The coefficient of variation in performance time for a swimmer between races was 0.60% (95% confidence limits 0.56 to 0.65%) within a competition and 0.80% (95% confidence limits 0.73 to 0.86%) between competitions. Our results show that: (a) to stay in contention for a medal, an Olympic swimmer should improve his or her performance by approximately 1% within a competition and by approximately 1% within the year leading up to the Olympics; (b) an additional enhancement of approximately 0.4% (one-half the between-competition variability) would substantially increase the swimmer's chances of a medal.

    Standardized assessment of sports injuries provides important epidemiological information and also directions for injury prevention. To analyze the frequency, characteristics, and causes of injuries incurred during the Summer Olympic Games 2008. Descriptive epidemiology study. The chief physicians and/or chief medical officers of the national teams were asked to report daily all injuries newly incurred during the Olympic Games on a standardized injury report form. In addition, injuries were reported daily by the physicians at the medical stations at the different Olympic venues and at the polyclinic in the Olympic Village. Physicians and/or therapists of 92 national teams covering 88% of the 10,977 registered athletes took part in the study. In total, 1055 injuries were reported, resulting in an incidence of 96.1 injuries per 1000 registered athletes. Half of the injuries (49.6%) were expected to prevent the athlete from participating in competition or training. The most prevalent diagnoses were ankle sprains and thigh strains. The majority (72.5%) of injuries were incurred in competition. One third of the injuries were caused by contact with another athlete, followed by overuse (22%) and noncontact incidences (20%). Injuries were reported from all sports, but their incidence and characteristics varied substantially. In relation to the number of registered athletes, the risk of incurring an injury was highest in soccer, taekwondo, hockey, handball, weightlifting, and boxing (all >or=15% of the athletes) and lowest for sailing, canoeing/kayaking, rowing, synchronized swimming, diving, fencing, and swimming. The data indicate that the injury surveillance system covered almost all of the participating athletes, and the results highlight areas of high risk for sport injury such as the in-competition period, the ankle and thigh, and specific sports. The identification of these factors should stimulate future research and subsequent policy change to prevent injury in

    To understand pathogen patterns of enteric infectious diseases and its impact on this pattern due to aggregation of a great deal of foreign visitors during Beijing Olympic Games. The diarrheal patient's rectal swabs and stool specimens were collected from Olympic stadium and hospitals of four districts, including Dongcheng, Xicheng, Haidian and Chaoyang. Enteric multiple pathogens were detected from the total 45 specimens. The culture method was used for the enteric bacteria, ELISA and RT-PCR for the enteric viruses. Molecular typing of Salmonella Enteritidis isolation was completed by PFGE. It was found that 26 out of 45 cases were positive with 57.8 percent for pathogen detection, and 24 were identified as enteric pathogenic bacteria, including Vibrio parahaemolyticus, Salmonella, diarrheagenic Escherichia coli and Campylobacter jejuni, two as norovirus. There were mixed infections of two pathogenic bacteria for three cases. Ten kinds of pathogens were detected from foreign cases, while five kinds from Chinese cases. A total of 5 PFGE patterns were identified in 10 Salmonella Enteritidis isolates from national and foreign diarrheal cases, which were concentrative in some extent. Vibrio parahaemolyticus, Salmonella, diarrheagenic Escherichia coli and Campylobacter jejuni were found to be the primary bacterial pathogens during the Olympic Games. Enteric virus infection existed in summer diarrhea.

    The tobacco industry has long sought affiliation with major sporting events, including the Olympic Games, for marketing, advertising and promotion purposes. Since 1988, each Olympic Games has adopted a tobacco-free policy. Limited study of the effectiveness of the smoke-free policy has been undertaken to date, with none examining the tobacco industry's involvement with the Olympics or use of the Olympic brand. A comparison of the contents of Olympic tobacco-free policies from 1988 to 2014 was carried out by searching the websites of the IOC and host NOCs. The specific tobacco control measures adopted for each Games were compiled and compared with measures recommended by the WHO Tobacco Free Sports Initiative and Article 13 of the Framework Convention on Tobacco Control (FCTC). This was supported by semi-structured interviews of key informants involved with the adoption of tobacco-free policies for selected games. To understand the industry's interests in the Olympics, the Legacy Tobacco Documents Library (http://legacy.library.ucsf.edu) was systematically searched between June 2013 and August 2014. Company websites, secondary sources and media reports were also searched to triangulate the above data sources. This paper finds that, while most direct associations between tobacco and the Olympics have been prohibited since 1988, a variety of indirect associations undermine the Olympic tobacco-free policy. This is due to variation in the scope of tobacco-free policies, limited jurisdiction and continued efforts by the industry to be associated with Olympic ideals. The paper concludes that, compatible with the IOC's commitment to promoting healthy lifestyles, a comprehensive tobacco-free policy with standardized and binding measures should be adopted by the International Olympic Committee and all national Olympic committees.

    Ferroelectric material supports both pyro- and piezoelectric effects that can be used for sensing pressures on large, bended surfaces. We present PyzoFlex, a pressure-sensing input device that is based on a ferroelectric material (PVDF:TrFE). It is constructed by a sandwich structure of four layers that can easily be printed on any substrate. The PyzoFlex foil is sensitive to pressure- and temperature changes, bendable, energy-efficient, and it can easily be produced by a screen-printing routine. Even a hovering input-mode is feasible due to its pyroelectric effect. In this paper, we introduce this novel, fully printed input technology and discuss its benefits and limitations.

    We use the high spatial sensitivity of the anomalous Hall effect in the ferromagnetic semiconductor Ga(1-x)Mn(x)As, combined with the magneto-optical Kerr effect, to probe the nanoscale elastic flexing behavior of a single magnetic domain wall in a ferromagnetic thin film. Our technique allows position sensitive characterization of the pinning site density, which we estimate to be ∼10(14) cm(-3). Analysis of single site depinning events and their temperature dependence yields estimates of pinning site forces (10 pN range) as well as the thermal deactivation energy. Our data provide evidence for a much higher intrinsic domain wall mobility for flexing than previously observed in optically probed μm scale measurements.

    A gas-insulated transmission line includes an outer sheath, an inner conductor, an insulating gas electrically insulating the inner conductor from the outer sheath, and insulating supports insulatably supporting the inner conductor within the outer sheath. The inner conductor is provided with flexibility by the use of main conductor sections which are joined together through a conductor hub section and flexible flexing elements. Stress shields are provided to control the electric field at the locations of the conductor hub sections where the insulating supports are contacting the inner conductor. The flexing elements are formed by sandwiching together, by fusing, a pair of thin hollow discs which are fixedly secured to both the main conductor sections and the conductor hub section.

    The True-Flex nail was used in 23 selected non-pathological and eight pathological fractures/lesions of the humeral shaft. The overall fracture union rate was 69.5 per cent and the patients achieved a good range of movement of the shoulder and elbow. Nailing did not lead to union of established non-unions or fractures which were previously treated unsuccessfully by surgery despite bone grafting. All patients with pathological fractures/lesions regained good function of the arm and a good range of movement of the shoulder and the elbow. In one case the nail migrated proximally and impinged on the rotator cuff. This was revised. No other technical difficulties or complications were seen. The True-Flex nail is useful in the treatment of difficult and relatively recent humeral shaft fractures. Established non-unions or cases where previous surgery has failed should be treated by alternative methods.

    The Fluorescence Explorer (FLEX) mission has been recently selected as the 8th Earth Explorer by the European Space Agency (ESA). It will be the first mission specifically designed to measure from space vegetation fluorescence emission, by making use of very high spectral resolution imaging spectroscopy techniques. Vegetation fluorescence is the best proxy to actual vegetation photosynthesis which can be measurable from space, allowing an improved quantification of vegetation carbon assimilation and vegetation stress conditions, thus having key relevance for global mapping of ecosystems dynamics and aspects related with agricultural production and food security. The FLEX mission carries the FLORIS spectrometer, with a spectral resolution in the range of 0.3 nm, and is designed to fly in tandem with Copernicus Sentinel-3, in order to provide all the necessary spectral / angular information to disentangle emitted fluorescence from reflected radiance, and to allow proper interpretation of the observed fluorescence spatial and temporal dynamics.

    As is well recognized, source mask optimization (SMO) is a highly effective means of extending the lifetime of a certain photolithography generation without an expensive upgrade to the next generation optical system. More than an academic theory, source optimization first found practical applications in the debut of the pixel-like programmable illuminator in 2009 for producing near freeform illumination. Based on programmed illumination, related studies have demonstrated a nearly identical optical performance to that generated by the conventionally adopted diffractive optical element (DOE) device without the prolonged manufacturing time and relatively high cost of stocking up various DOEs. By using a commercially available pixel-like programmable illuminator from ASML, i.e. the FlexRay, this study investigates the effectiveness of FlexRay in enhancing image contrast and common process window. Before wafer exposure, full SMO and source-only (SO) optimization are implemented by Tachyon SMO software to select the optimum illumination source. Wafer exposure is performed by ASML XT:1950i scanner equipped with a FlexRay illuminator on a critical layer of DRAM process with known hotspots of resist peeling. Pupil information is collected by a sensor embedded in the scanner to confirm the produced source shape against the programmed source and the optically simulated CD. When the FlexRay illuminator is used, experimental results indicate that lithography hotspots are eliminated and depth of focus is improved by as much as 50% in comparison with those from a traditional AERIAL illuminator. Regular focus-exposure matrix (FEM) and the subsequent critical defects scanning reveal that the common process window of the tight-pitched array and the periphery can be enhanced simultaneously with no hotspot identified. Therefore, a programmed source is undoubtedly invaluable in terms of additional manufacturing flexibility and lower cost of ownership when attempting to improve product

    The FlexSAR radar system was designed to be a high quality, low-cost, flexible prototype instrument. Many radar researchers and practitioners desire the ability to efficiently prototype novel configurations. However, the cost and time required to modify existing radar systems is a challenging hurdle that can be prohibitive. The FlexSAR system couples an RF design that leverages connectorized components with digital commercial-off-the-shelf (COTS) cards. This design allows for a scalable system that supports software defined radio (SDR) capabilities. This paper focuses on the RF and digital system design, discussing the advantages and disadvantages. The FlexSAR system design objective was to support diverse configurations with minimal non-recurring engineering (NRE) costs. Multiple diverse applications are examined, demonstrating the flexible system nature. The configurations discussed utilize different system parameters (e.g., number of phase-centers, transmit configurations, etc.). The resultant products are examined, illustrating that high-quality data products are still attained.

    The FlexSAR radar system was designed to be a high quality, low-cost, flexible research prototype instrument. Radar researchers and practitioners often desire the ability to prototype new or advanced configurations, yet the ability to enhance or upgrade existing radar systems can be cost prohibitive. FlexSAR answers the need for a flexible radar system that can be extended easily, with minimal cost and time expenditures. The design approach focuses on reducing the resources required for developing and validating new advanced radar modalities. Such an approach fosters innovation and provides risk reduction since actual radar data can be collected in the appropriate mode, processed, and analyzed early in the development process. This allows for an accurate, detailed understanding of the corresponding trade space. This paper is a follow-on to last years paper and discusses the advancements that have been made to the FlexSAR system. The overall system architecture is discussed and presented along with several examples illustrating the system utility.

  15. Stress analysis of plated-through-holes in rigid flex multilayer printed wiring boards

    A rigid/flex printed wiring board is a hybridized system of wiring interconnects utilizing the concepts of both multilayer and flexible circuit technology. This type of printed wiring board offers significant advantages in the production of complex electronic assemblies. In contrast to standard printed wiring board assemblies which are homogeneous in material composition, rigid/flex assemblies have a combination of different laminates, films, and adhesives arranged to accomplish the electrical and mechanical design goals. After lamination, the circuit layers are interconnected using plated-through-hole technology. Associated with the plated-through-holes are at least two observed failure modes, barrel cracks and inner layer foil cracks, that develop during thermal testing of completed printed wiring board assemblies. Due to these failures, there is concern about the reliability of such systems. This paper presents the results from finite element stress analyses employed to assist in the understanding of failure modes in a plated-through-hole of a rigid/flex multilayer printed wiring board. The results of the analyses provided substantial insight about the thermal-structural response of the assembly and provided guidance to process improvements aimed at eliminating the failures. 6 refs.

    Golden Gate cloning is a prominent DNA assembly tool in synthetic biology for the assembly of plasmid constructs often used in combinatorial pathway optimization, with a number of assembly kits developed specifically for yeast and plant-based expression. However, its use for synthetic biology in commonly used bacterial systems such as Escherichia coli has surprisingly been overlooked. Here, we introduce EcoFlex a simplified modular package of DNA parts for a variety of applications in E. coli, cell-free protein synthesis, protein purification and hierarchical assembly of transcription units based on the MoClo assembly standard. The kit features a library of constitutive promoters, T7 expression, RBS strength variants, synthetic terminators, protein purification tags and fluorescence proteins. We validate EcoFlex by assembling a 68-part containing (20 genes) plasmid (31 kb), characterize in vivo and in vitro library parts, and perform combinatorial pathway assembly, using pooled libraries of either fluorescent proteins or the biosynthetic genes for the antimicrobial pigment violacein as a proof-of-concept. To minimize pathway screening, we also introduce a secondary module design site to simplify MoClo pathway optimization. In summary, EcoFlex provides a standardized and multifunctional kit for a variety of applications in E. coli synthetic biology.

  17. Clinically Constrained Optimization of flexTPI Acquisition Parameters for the Tissue Sodium Concentration Bioscale

    The rapid transverse relaxation of the sodium magnetic resonance (MR) signal during spatial encoding causes a loss of image resolution, an effect known as T2-blurring. Conventional wisdom suggests that spatial resolution is maximized by keeping the readout duration as short as possible to minimize T2-blurring. Flexible twisted projection imaging (flexTPI) performed with an ultra-short echo time, relative to T2, and a long repetition time, relative to T1, has been shown to be effective for quantitative sodium MR imaging. A minimized readout duration requires a very large number of projections and, consequentially, results in an impractically long total acquisition time to meet these conditions. When the total acquisition time is limited to a clinically practical duration (e.g., 10 minutes), the optimal parameters for maximal spatial resolution of a flexTPI acquisition do not correspond to the shortest possible readout. Simulation and experimental results for resolution optimized acquisition parameters of quantitative sodium flexTPI of parenchyma and cerebrospinal fluid are presented for the human brain at 9.4T and 3T. The effect of signal loss during data collection on sodium quantification bias and image signal-to-noise ratio are discussed. PMID:21446034

    To evaluate the analytical performance of a new capillary electrophoresis instrument, the Capillarys 2 Flex piercing (Sebia, France), allowing the separation and quantitative estimation of the different haemoglobin fractions from whole blood, in capped primary tube.The analytical precision for the determination of HbA2 and HbF percentages was satisfactory and within the range of previously published results for HPLC methods. The correlation between Capillarys 2 Flex Piercing and Bio-Rad Variant II HPLC system showed a linear correlation for HbA2, HbF and HbS measurements, and the analysis interpretation was the same whatever the method used. Conversely to HPLC method, the capillary's electrophoresis technology allowed HbE and Hb Lepore fraction separation from HbA2. We showed that the Capillarys 2 Flex Piercing is suitable for haemoglobinopathies diagnosis and screening and offers an excellent alternative to HPLC techniques as a first-line method or for confirmatory analysis.

    FROST (Forecast and Research: the Olympic Sochi Testbed) 2014 is a WMO WWRP international project aimed at development, implementation, and demonstration of capabilities of short-range numerical weather prediction and nowcasting technologies for mountainous terrain in winter season. Sharp weather contrasts and high spatial and temporal variability are typical for the region of the Sochi-2014 Olympics. Steep mountainous terrain and an intricate mixture of maritime sub-tropical and Alpine environments make weather forecasting in this region extremely challenging. Goals of the FROST-2014 project: • To develop a comprehensive information resource of Alpine winter weather observations; • To improve and exploit: o Nowcasting systems of high impact weather phenomena (precipitation type and intensity, snow levels, visibility, wind speed, direction and gusts) in complex terrain; o High-resolution deterministic and ensemble mesoscale forecasts in winter complex terrain environment; • To improve the understanding of physics of high impact weather phenomena in the region; • To deliver forecasts (Nowcasts) to Olympic weather forecasters and decision makers and assess benefits of forecast improvement. 46 Automatic Meteorological Stations (AMS) were installed in the Olympic region by Roshydromet, by owners of sport venues and by the Megafon corporation, provider of mobile communication services. The time resolution of AMS observations does not exceed 10 minutes. For a subset of the stations it is even equal to 1 min. Data flow from the new dual polarization Doppler weather radar WRM200 in Sochi was organized at the end of 2012. Temperature/humidity and wind profilers and two Micro Rain Radars (MRR) will supplement the network. Nowcasting potential of NWP models participating in the project (COSMO, GEM, WRF, AROME, HARMONIE) is to be assessed for direct and post-processed (e.g. Kalman filter, 1-D model, MOS) model forecasts. Besides the meso-scale models, the specialized

    Aggressive traffic intervention and emission control measures implemented during the 2008 Olympic Games in Beijing created a valuable case study for evaluating the effectiveness of measures for mitigating environmental pollution and protecting public health. Results are reported here for a suite of magnetic and non-magnetic (microscopic, chemical and statistical) methods conducted on street dust deposits and parkland soils around the Olympic Park in Beijing. In both areas magnetic grains with multidomain properties predominate; grain sizes are coarser in the heavy traffic regions and finer in the park areas with evidence for particulate steel dust input in the former case. Traffic is the major source of anthropogenic magnetic particle-induced enhancement of magnetic susceptibility in street dust; however, domestic combustion processes (mainly coal burning) are found to contribute a significant magnetic signature in the urban environment during the winter. Due to the traffic intervention, magnetic compositions in street dust decreases significantly during the Olympic Games. Correlations between magnetic parameters and heavy metal contents prove that magnetic parameters can be used as proxies for heavy metal pollution.

    The limitations of the Standard Model of particle physics, despite its being a well-established theory, have prompted various proposals for new physics capable of addressing its shortcomings. The particular issue to be explored here is the mechanism of electroweak symmetry breaking, the probing of which lies within the TeV-scale physics accessible to the Large Hadron Collider (LHC). This thesis focuses on the phenomenology of a class of models featuring a dynamical breaking of the electroweak symmetry via strong dynamics. Consequences of recent experiments and aspects of near-future experiments are presented. We study the implications of the LHC Higgs searches available at the time the related journal article was written for technicolor models that feature colored technifermions. Then we discuss the properties of a technicolor model featuring strong-top dynamics that is viable for explaining the recently discovered boson of mass 126 GeV. We introduce a novel method of characterizing the color structure of a new massive vector boson, often predicted in various new physics models, using information that will be promptly available if it is discovered in the near-future experiments at the LHC. We generalize the idea for more realistic models where a vector boson has flavor non-universal couplings to quarks. Finally, we discuss the possibilities of probing the chiral structure of a new color-octet vector boson.

    2015-08-25

    The search for di-Higgs production at the LHC in order to set limits on the Higgs trilinear coupling and constraints on new physics is one of the main motivations for the LHC high-luminosity phase. Recent experimental analyses suggest that such analyses will only be successful if information from a range of channels is included. We therefore investigate di-Higgs production in association with two hadronic jets and give a detailed discussion of both the gluon- and the weak boson-fusion (WBF) contributions, with a particular emphasis on the phenomenology with modified Higgs trilinear and quartic gauge couplings. We perform a detailed investigationmore » of the full hadronic final state and find that hhjj production should add sensitivity to a di-Higgs search combination at the HL-LHC with 3 ab-1. Since the WBF and GF contributions are sensitive to different sources of physics beyond the Standard Model, we devise search strategies to disentangle and isolate these production modes. In addition, while gluon fusion remains non-negligible in WBF-type selections, sizeable new physics contributions to the latter can still be constrained. As an example of the latter point we investigate the sensitivity that can be obtained for a measurement of the quartic Higgs–gauge boson couplings.« less

    The discovery of a Higgs boson at CERN in 2012 is the start of a major program of work to measure this particle's properties with the highest possible precision for testing the validity of the Standard Model and to search for further new physics at the energy frontier. The LHC is in a unique position to pursue this program. Europe's top priority is the exploitation of the full potential of the LHC, including the high-luminosity upgrade of the machine and detectors with an objective to collect ten times more data than in the initial design, by around 2030. To reach this objective, the LHC cryogenic system must be upgraded to withstand higher beam current and higher luminosity at top energy while keeping the same operation availability by improving the collimation system and the protection of electronics sensitive to radiation. This chapter will present the conceptual design of the cryogenic system upgrade with recent updates in performance requirements, the corresponding layout and architecture of the system as well as the main technical challenges which have to be met in the coming years.

    A microfluidic device (the HistoFlex) designed to perform and monitor molecular biological assays under dynamic flow conditions on microscope slide-substrates, with special emphasis on analyzing histological tissue sections, is presented. Microscope slides were reversibly sealed onto a cast polydimethylsiloxane (PDMS) insert, patterned with distribution channels and reaction chambers. Topology optimization was used to design reaction chambers with uniform flow conditions. The HistoFlex provided uniform hybridization conditions, across the reaction chamber, as determined by hybridization to microscope slides of spotted DNA microarrays when applying probe concentrations generally used in in situ hybridization (ISH) assays. The HistoFlex's novel ability in online monitoring of an in situ hybridization assay was demonstrated using direct fluorescent detection of hybridization to 18S rRNA. Tissue sections were not visually damaged during assaying, which enabled adapting a complete ISH assay for detection of microRNAs (miRNA). The effects of flow based incubations on hybridization, antibody incubation and Tyramide Signal Amplification (TSA) steps were investigated upon adapting the ISH assay for performing in the HistoFlex. The hybridization step was significantly enhanced using flow based incubations due to improved hybridization efficiency. The HistoFlex device enabled a fast miRNA ISH assay (3 hours) which provided higher hybridization signal intensity compared to using conventional techniques (5 h 40 min). We further demonstrate that the improved hybridization efficiency using the HistoFlex permits more complex assays e.g. those comprising sequential hybridization and detection of two miRNAs to be performed with significantly increased sensitivity. The HistoFlex provides a new histological analysis platform that will allow multiple and sequential assays to be performed under their individual optimum assay conditions. Images can subsequently be recorded either in

    To minimize the beam losses at the moment of an LHC beam dump the 3 μs long abort gap should contain as few particles as possible. Its population can be minimised by abort gap cleaning using the LHC transverse damper system. The LHC Run 1 experience is briefly recalled; changes foreseen for the LHC Run 2 are presented. They include improvements in the observation of the abort gap population and the mechanism to decide if cleaning is required, changes to the hardware of the transverse dampers to reduce the detrimental effect on the luminosity lifetime and proposed changes to the applied cleaning algorithms.

    The concept of Olympic education and its use of moral education to shape the development of personality have received insufficient empirical support. The aim of this study was to examine the effects of an integrated Olympic education programme on the development of prosocial behaviour in adolescents. A natural experimental research design was applied in this study. The pre-test sample included 411 adolescents (aged 13-14) who were randomly selected from schools that had begun to apply an integrated Olympic education programme, along with 430 adolescents from schools without an Olympic education programme. The post-test sample included 381 students from schools implementing the Olympic education programme and 402 students from schools without an Olympic education programme. The revised prosocial tendencies measure was administered to the participants at pre- and post-test time points to assess changes in prosocial behaviour and specifically on six types of prosocial behaviour: public, anonymous, dire, emotional, compliant, and altruistic. The analyses showed significant improvements in prosocial behaviour in adolescents from schools that had implemented an integrated Olympic education programme. Changes in prosocial behaviour following the implementation of an integrated Olympic education programme were observed for the compliant, altruistic, and dire types of prosocial behaviour. In conclusion, these findings suggest that an integrated Olympic education programme effectively encourages prosocial behaviour in adolescents. This study expands our understanding of the efficiency of implementing an Olympic education programme in schools. We suggest that future research should investigate the behavioural changes in students of different ages from perspective of both teachers and students.

J Strength Cond Res 31(8): 2208-2215, 2017-Anecdotal data suggest an increase in the age of Olympic swimmers, but scientific studies in this regard are scarce, despite the importance for coaches of the confirmation of this increase in different styles. To ascertain the reality of this increase, this study focused on the analysis of the data contained in the reports of the Internal Olympic Games Association, covering different events and styles throughout the history of the Games. Starting with the 1908 Games, a total of 806 swimmers (436 men and 370 women) were included in the study. Of them, 137 men and 135 women had won 2 or more medals. Plots of the age of the swimmer at the time a gold, silver, or bronze medal was granted versus year of competition elicited statistical significant increases in 3 events in men and 9 events in women. Interestingly, significant increases were regularly observed in the styles introduced in the 60s, and a kind of V-shaped distribution was observed in some of the long established competitions, namely in the 100, 400 and 1,500 m freestyle in men, where the point of inflexion seems to occur around 1960. Overall, there is a continuing increase in the age of swimmers of ages over 24 years mirrored by a decrease of those younger than 20 years, and this is accompanied by the increased presence of swimmers that have won medals in 2 or 3 different Games.

    The age-related progression of elite athletes to their career-best performances can provide benchmarks for talent development. The purpose of this study was to model career performance trajectories of Olympic swimmers to develop these benchmarks. We searched the Web for annual best times of swimmers who were top 16 in pool events at the 2008 or 2012 Olympics, from each swimmer's earliest available competitive performance through to 2012. There were 6959 times in the 13 events for each sex, for 683 swimmers, with 10 ± 3 performances per swimmer (mean ± s). Progression to peak performance was tracked with individual quadratic trajectories derived using a mixed linear model that included adjustments for better performance in Olympic years and for the use of full-body polyurethane swimsuits in 2009. Analysis of residuals revealed appropriate fit of quadratic trends to the data. The trajectories provided estimates of age of peak performance and the duration of the age window of trivial improvement and decline around the peak. Men achieved peak performance later than women (24.2 ± 2.1 vs. 22.5 ± 2.4 years), while peak performance occurred at later ages for the shorter distances for both sexes (∼1.5-2.0 years between sprint and distance-event groups). Men and women had a similar duration in the peak-performance window (2.6 ± 1.5 years) and similar progressions to peak performance over four years (2.4 ± 1.2%) and eight years (9.5 ± 4.8%). These data provide performance targets for swimmers aiming to achieve elite-level performance.

  11. MSSM forecast for the LHC

    2010-05-01

    We perform a forecast of the MSSM with universal soft terms (CMSSM) for the LHC, based on an improved Bayesian analysis. We do not incorporate ad hoc measures of the fine-tuning to penalize unnatural possibilities: such penalization arises from the Bayesian analysis itself when the experimental value of M Z is considered. This allows to scan the whole parameter space, allowing arbitrarily large soft terms. Still the low-energy region is statistically favoured (even before including dark matter or g-2 constraints). Contrary to other studies, the results are almost unaffected by changing the upper limits taken for the soft terms. The results are also remarkable stable when using flat or logarithmic priors, a fact that arises from the larger statistical weight of the low-energy region in both cases. Then we incorporate all the important experimental constrains to the analysis, obtaining a map of the probability density of the MSSM parameter space, i.e. the forecast of the MSSM. Since not all the experimental information is equally robust, we perform separate analyses depending on the group of observables used. When only the most robust ones are used, the favoured region of the parameter space contains a significant portion outside the LHC reach. This effect gets reinforced if the Higgs mass is not close to its present experimental limit and persits when dark matter constraints are included. Only when the g-2 constraint (based on e + e - data) is considered, the preferred region (for μ > 0) is well inside the LHC scope. We also perform a Bayesian comparison of the positive- and negative- μ possibilities.

    The Large Hadron Collider has had a trying start-up and a challenging operational future lays ahead. Critical to the machine's performance is controlling a beam of particles whose stored energy is equivalent to 80 kg of TNT. Unavoidable beam losses result in energy deposition throughout the machine and without adequate protection this power would result in quenching of the superconducting magnets. A brief overview of the machine layout and principles of operation will be reviewed including a summary of the September 2008 accident. The current status of the LHC, startup schedule and upgrade options to achieve the target luminosity will be presented.

    The victors of the Olympic Games in ancient Greece were awarded crowns made of olive branches. In Antiquity, the symbolism of plants was related to myths, properties, aesthetic values, and civilization. Theophrastus first classifies and identifies plants, and gathers information about them, in his classic books (4th century BC). Symbolic plants are native to the Mediterranean region and they exhibit some convergent behaviour with respect to their functional characteristics. These plants were collected (among other species) by Professor J. Sibthorp and his partners in two botanical journeys in the Levant during the 18th century, and they have been illustrated for Flora Graeca Sibthorpiana.

    Athletes' kinanthropometric profiles are widely addressed in the scientific literature. Such profiles are particularly important in volleyball because absolute size contributes a significant percentage of total variance associated with athletic success. As in other team sports, volleyball players' kinanthropometric attributes correlate with the game's tactical demands. From 1992 through 2000, the Cuban women's volleyball team achieved top global performance, winning first place in three successive Summer Olympic Games. Describe the kinanthropometric profiles of Cuban women Olympic volleyball champions during 1992-2000 and compare these by position played. Measurements were taken of body composition, somatotype, proportionality and several anthropometric indicators in 41 Cuban women volleyball players, grouped by playing position. All were members of the national team that participated in the Summer Olympic Games in Barcelona (1992), Atlanta (1996) and Sydney (2000). Mean and standard deviations were calculated for all study variables. Analysis of variance was used to compare means for different positions for the variables weight; height; percent adipose, muscle and bone mass; body mass index; and muscle-to-bone ratio. Discriminant analysis was performed to identify anthropometric dimensions differentiating playing positions (center, spiker and setter), using p<0.05 as significance threshold. Results were presented in tables and figures. Centers presented greater absolute size and higher average adipose (22.8±1.7 kg) and bone (7.1±0.6 kg) mass. The mean somatotype of all volleyball players was balanced mesomorphic (2.7-3.6-2.9). Classified by position, centers (2.9-3.4-3.4) and spikers (2.8-3.6-2.9) presented an average mesomorphic-ectomorphic somatotype, and setters (2.6-3.7-2.6) were balanced mesomorphic. On assessing Somatotype Attitudinal Mean (SAM), centers and spikers showed more intrapositional homogeneity than that of setters. Centers were significantly

  19. Towards improved quantification of vegetation photosynthetic activity at global scale: the FLuorescence EXplorer (FLEX) mission

    NASA Astrophysics Data System (ADS)

    Moreno, Jose

    2014-05-01

    The fluorescence signal, originated from the core complexes of the photosynthetic machinery, is a sensitive indicator of the actual photosynthesis in both healthy and physiologically stressed vegetation, which can be used as a powerful non-invasive marker to track the status, resilience, and recovery of photochemical processes. This is of particular interest for the improvements in the predictive capability of global carbon cycle models through new parameterizations for canopy photosynthesis and the corresponding exchange processes of energy, water and carbon between the surface and the atmosphere. The shape of the fluorescence emission spectrum consists of two peaks having broad bands with maxima around 685 nm and 740 nm. The variations in amplitude and shape of the emission reflect the efficiency of photosynthetic electron transport. The integral of the overall fluorescence emission provides information about actual photosynthetic light conversion. The shape of the emission spectrum provides additional information about the vegetation health status. While most of the information that has been acquired by remote sensing of the Earth's surface about vegetation conditions and photosynthetic activity has come from "reflected" light in the solar domain, the ESA's Earth Explorer candidate FLEX (Fluorescence EXplorer) mission is the first space mission focused on the estimation of fluorescence emission by terrestrial vegetation on a global scale with high spatial resolution and resolving the spectral shape of fluorescence emission. The FLEX mission also includes explicit measurement of photochemical changes in reflectance (i.e., PRI), canopy temperature measurements and all the relevant variables (chlorophyll content, Leaf Area Index, etc.) needed to asses the actual physiological status of vegetation and to provide quantitative estimates of photosynthetic rates and gross primary production. FLEX is one of two candidate Earth Explorer-8 missions currently under Phase A

    The purpose of this study was to evaluate whether transporting insulin aspart FlexPens via a pneumatic tube system affects the dosing accuracy of the pens. A total of 115 Novo Nordisk FlexPens containing insulin aspart were randomly assigned to be transported via a pneumatic tube system (n = 92) or to serve as the control (n = 23). Each pen was then randomized to 10 international unit (IU) doses (n = 25) or 30 IU doses (n = 67), providing 600 and 603 doses, respectively, for the pneumatic tube group. The control group also received random assignment to 10 IU doses (n = 6) or 30 IU doses (n = 17), providing 144 and 153 doses, respectively. Each dose was expelled using manufacturer instructions. Weights were recorded, corrected for specific gravity, and evaluated based on acceptable International Organization for Standardization (ISO) dosing limits. In the group of pens transported through the pneumatic tube system, none of the 600 doses of 10 IU (0.0%; 95% CI, 0.0 to 0.6) and none of the 603 doses of 30 IU (0.0%; 95% CI, 0.0 to 0.6) fell outside of the range of acceptable weights. Correspondingly, in the control group, none of the 144 doses at 10 IU (0.0%; 95% CI, 0.0 to 2.5) and none of the 153 doses at 30 IU (0.0%; 95% CI, 0.0 to 2.4) were outside of acceptable ISO limits. Transportation via pneumatic tube system does not appear to compromise dosing accuracy. Hospital pharmacies may rely on the pneumatic tube system for timely and accurate transport of insulin aspart FlexPens.

    Background It is commonly believed in medicine that using heat will increase the distensability and flexibility of soft tissue. If true, increased flexibility would be a positive factor to reduce injuries in sports. However, cold should have the opposite effect and is often used to treat sports injuries. This study was accomplished to quantify the effect of heat and cold on the force needed to flex the knee and laxness of the anterior and posterior cruciate ligaments. Material/Methods The present study examined 20 male and female subjects to determine if heat would increase extensibility of the anterior and posterior cruciate ligaments of the knee and reduce the force needed to flex the knee. Cold exposure was examined to see if it would have the opposite effect. There were 4 experiments in the series: The first was a room temperature series; the second was a series where cold was applied with an ice pack for 20 minutes; in the third, hydrocollator heat packs were applied for 20 minutes; and in the fourth, ThermaCare heat wraps were applied for 4 hours on the quadriceps and knee. Tendon extensibility was measured with a KT2000. The force for flexing the knee was measured by passive movement being applied (CPM) to the knee through 30° and the force required to move the leg was measured. Results The results show that the anterior and posterior cruciate ligament flexibility increased and the force needed to move the knee decreased with heat by about 25% compared to cold application. Conclusions Heat is beneficial in increasing muscle and ligament flexibility and may help reduce athletic injuries, but cold treatment may have the opposite effect. PMID:23933600

    The present ground based investigations give the first definitive look describing the expected on-orbit charging behavior of Orion UltraFlex array coupons in the Low Earth Orbital and Geosynchronous Environments. Furthermore, it is important to note that the LEO charging environment also applies to the International Space Station as well as to the lunar mission charging environments. The GEO charging environment includes the bounding case for all lunar orbital and lunar surface mission environments. The UltraFlex thin film photovoltaic array technology has been targeted to become the sole power system for life support and on-orbit power for the manned Aires Crew Exploration Vehicle. It is therefore, crucial to gain an understanding of the complex charging behavior to answer some of the basic performance and survivability issues in an attempt to ascertain that a single UltraFlex array design will be able to cope with the projected worst case LEO and GEO charging environments. Testing was limited to four array coupons, two coupons each from two different array manufactures, Emcore and Spectrolab. The layout of each array design is identical and varies only in the actual cell technology used. The individual array cells from each manufacturer have an antireflection layered coating and come in two different varieties either uncoated (only AR coating) or coated with a thin conducting ITO layer. The LEO Plasma tests revealed that all four coupons passed the arc threshold -120 V bias tests. GEO electron gun charging tests revealed that only front side area of ITO coated coupons passed tests. Only the Emcore AR array passed backside Stage 2 GEO Tests.

    Commissioning the Large Hadron Collider (LHC) and its experiments will be a vital part of the worldwide high energy physics program beginning in 2007. A remote operations center has been built at Fermilab to contribute to commissioning and operations of the LHC and the Compact Muon Solenoid (CMS) experiment, and to develop new capabilities for real-time data analysis and monitoring for LHC, CMS, and grid computing. Remote operations will also be essential to a future International Linear Collider with its multiple, internationally distributed control rooms. In this paper we present an overview of Fermilab's LHC@FNAL remote operations center for LHC and CMS, describe what led up to the development of the center, and describe noteworthy features of the center.

    The lay press, scientists, and physicians appear to believe that gymnasts are continually getting smaller and that their "smallness" is a health risk. To assess the historical changes in the size and age of the US women's Olympic gymnastics teams from 1956 to 2008. The official records from the US Olympic Committee and USA Gymnastics of Olympic team members were assessed at 2 levels: individual height, mass, age, and body-mass index (BMI) and the team performance scores and rankings. Fourteen Olympic teams with a total of 106 team members, including the alternates, were included. Trend analyses were conducted using linear and polynomial models. Simple linear correlations indicated that since 1956, height, mass, age, BMI, and team Olympic rank have been declining. However, second-order polynomial curve fits indicated that in the last 4 Olympic Games the members of the US women's gymnastics teams have been getting larger. Women Olympic gymnasts were getting smaller through approximately the 1980s and early 1990s. Since then the size of these gymnasts has increased. The minimum-age rule modifications may have played a role in athlete size changes along with a shift from the near dominance of the former communist Eastern Bloc.

    Rigid/flex multilayer printed wiring boards are more sensitive to thermal environmental changes than conventional printed wiring boards. This is manifested because of a composition of dissimilar materials used within the construction of this type of product. During fabrication and assembly, stresses can develop within the plated-through holes from differences in thermal properties of the rigid and flexible materials, primarily thermal coefficient of expansion. Thermal shock and thermal stress tests and rework simulation as defined in MIL-P-50884 have been performed in this study as indicators of processing quality to detect faults and to verify improvements in board reliability. 3 refs., 17 figs., 3 tabs.

    The development of the flex-seal component of the P80 nozzle gave the opportunity to set up new design and manufacturing process methods. Due to the short development lead time required by VEGA program, the usual manufacturing iterative tests work flow, which is usually time consuming, had to be enhanced in order to use a more predictive approach. A newly refined rubber vulcanization description was built up and identified on laboratory samples. This chemical model was implemented in a thermal analysis code. The complete model successfully supports the manufacturing processes. These activities were conducted with the support of ESA/CNES Research & Technologies and DGA (General Delegation for Armament).

    This paper discusses the application of robust control theory to evaluate robustness of the Ares-I control systems. Three techniques for estimating upper and lower bounds of uncertain parameters which yield stable closed-loop response are used here: (1) Monte Carlo analysis, (2) mu analysis, and (3) characteristic frequency response analysis. All three methods are used to evaluate stability envelopes of the Ares-I control systems with uncertain aerodynamics and flex dynamics. The results show that characteristic frequency response analysis is the most effective of these methods for assessing robustness.

    In patients undergoing laser lead extraction, incomplete or failed lead removal occur in over 3 % of leads. Because the current available tools have limitations in reaching the right ventricle (RV), the procedure becomes challenging when the lead breaks and its fragments remain lodged in the RV. We describe two cases in which the FlexCath® steerable sheath, normally used in cryoballoon catheter ablation for atrial fibrillation, was useful in directing a bioptome to right ventricular lead fragments and thus allowing for complete lead extraction.

    Tissue engineered heart valves (TEHV) have been observed to respond to mechanical conditioning in vitro by expression of activated myofibroblast phenotypes followed by improvements in tissue maturation. In separate studies, cyclic flexure, stretch, and flow (FSF) have been demonstrated to exhibit both independent and coupled stimulatory effects. Synthesis of these observations into a rational framework for TEHV mechanical conditioning has been limited, however, due to the functional complexity of tri-leaflet valves and the inherent differences of separate bioreactor systems. Toward quantifying the effects of individual mechanical stimuli similar to those that occur during normal valve function, a novel bioreactor was developed in which FSF mechanical stimuli can be applied to engineered heart valve tissues independently or in combination. The FSF bioreactor consists of two identically equipped chambers, each having the capacity to hold up to 12 rectangular tissue specimens (25 x 7.5 x 1 mm) via a novel "spiral-bound" technique. Specimens can be subjected to changes-in-curvature up to 50 mm(-1) and uniaxial tensile strains up to 75%. Steady laminar flow can be applied by a magnetically coupled paddlewheel system. Computational fluid dynamic (CFD) simulations were conducted and experimentally validated by particle image velocimetry (PIV). Tissue specimen wall shear stress profiles were predicted as a function of paddlewheel speed, culture medium viscosity, and the quasi-static state of specimen deformation (i.e., either undeformed or completely flexed). Velocity profiles predicted by 2D CFD simulations of the paddlewheel mechanism compared well with PIV measurements, and were used to determine boundary conditions in localized 3D simulations. For undeformed specimens, predicted inter-specimen variations in wall shear stress were on average +/-7%, with an average wall shear stress of 1.145 dyne/cm(2) predicted at a paddlewheel speed of 2000 rpm and standard culture

    A series of experiments has been run to examine the floating-point performance of FORTRAN programs on the Flex/32 (Trademark) computer. The experiments are described, and the timing results are presented. The time required to execute a floating-point operation is found to vary considerbaly depending on a number of factors. One factor of particular interest from an algorithm design standpoint is the difference in speed between common memory accesses and local memory accesses. Common memory accesses were found to be slower, and guidelines are given for determinig when it may be cost effective to copy data from common to local memory.

The observational prospective cohort study followed the Great Britain Injury/Illness Performance Project surveillance methodology and obtained information on injuries and illnesses that occurred during the Games between 30 January and 23 February 2014 in TeamGB athletes (n=56). Among the 56 TeamGB athletes, there were 27 injuries and 11 illnesses during the Olympic Games period. This equated to 39% sustaining at least one injury and 18% at least one illness, with an incidence of 48.2 injuries and 19.6 illnesses per 100 athletes, respectively. Of all injuries and illnesses, 9% and 7%, respectively, resulted in time loss. The risk of sustaining an injury was highest for freestyle skiing, skeleton and snowboarding; and lowest for curling, biathlon and Alpine skiing (with no reported injuries); with the lower limb being the most commonly injured location. Respiratory system illnesses were most frequently reported overall, and older female athletes were the ones most affected by illness. The risk of injury was double the risk of illness for TeamGB athletes. Overall, the rate of time-loss issues was low. Methodological considerations are important when interpreting data, and prevention strategies should focus on those issues causing the greatest risk, in terms of prevalence and severity, to athlete health and performance.

    2012-05-01

    Insulin injection pens have improved the ease and convenience of administering insulin for people with diabetes. This article reviews the data on a new prefilled insulin pen, FlexTouch®. FlexTouch has a novel injection mechanism with no push-button extension and a lower injection force than other prefilled pens, and other features including an end-of-dose click; a large dose display; color-coded pens to distinguish different insulin types; an ergonomic design; and compatibility with both NovoTwist® needles and most screw-thread needles. FlexTouch has been demonstrated to deliver insulin consistently and accurately at minimum, half-maximum and maximum doses. In usability studies recruiting patients and healthcare professionals, FlexTouch was easier to use and instilled more confidence than other prefilled pens, and was preferred to other prefilled pens. FlexTouch was also found to be easier to use and was preferred for learning and teaching to use.

    Diabetes is difficult to manage and treatment involves significant lifestyle adjustments. Unlike the traditional method of insulin administration via the vial and syringe method, insulin pens might be perceived as less cumbersome and have potential to significantly increase patient adherence. Using "real world" data, we examined the differences in adherence and costs between diabetic patients using an insulin FlexPen (Novo Nordisk Inc, Princeton, NJ, USA) and those using traditional vial and syringe administration. Using a retrospective analysis of health insurance claims data between the years 2003 and 2008, we examined patients in the FlexPen cohort and analog vial cohort. Propensity score matching was used to match these cohorts (n=532 in each) according to baseline characteristics. Adjusted mean medication possession ratio when switched to FlexPen improved by 22 percentage points versus 13 percentage points when continuing to use vials (P=0.001). Diabetes-related healthcare costs when switched to FlexPen versus continuing on to use vials ($3970 vs. $4838, respectively, P=0.9368) and total healthcare costs ($13,214 vs. $13,212, respectively, P=0.9473) were not statistically different. Without significant addition to the cost, insulin administration with FlexPen is associated with an improved adherence among patients who switched from vial-based insulin administration.

    Barrier integrity of unaged and oven-aged (at 70 degrees C) natural rubber latex examination gloves was assessed with a biaxial flex-fatigue method where failure was detected electronically, and by live viral penetration testing performed according to a modified version of ASTM F1671-97a. When no change in barrier properties was detected during flex testing, no virus passage was found after viral challenge. Conversely, when a change in the barrier properties was indicated by the electrical signal, virus passage was found in 74% of the specimens. Flex-fatigue results indicated that unaged test specimens from powdered (PD) and powder-free (PF) nonchlorinated gloves had significantly longer fatigue lives than powder-free chlorinated (CL) gloves from the same manufacturer. Biaxial flexing of oven-aged glove specimens showed a marginal increase in fatigue life for the PF gloves, but no increase for the PD gloves. The fatigue life of the CL gloves was observed to increase significantly after oven aging. However, this appears to be due to a design feature of the test apparatus, wherein peak volume displacement of the worked specimen is held constant. An aging-induced change in the viscoelastic properties of the CL gloves-permanent deformation of the specimens early in the fatigue test-relieves the stress magnitude applied as the test progresses. Thus, permanent deformation acts as a confounding factor in measuring durability of latex gloves by fixed displacement flex-fatigue.

    This article represents a retrospective analysis of medical care provided to spectators, athletes, officials, and workforce at the cross country skiing and biathlon venue, Soldier Hollow, during the 2002 Winter Olympic Games. A retrospective chart review was performed of the primary diagnosis category assigned to each patient on medical encounter forms completed at the time medical care was provided in the athlete or spectator medical clinics. Descriptive statistics were used to characterize data from the primary diagnosis categories for groups of patients. There were 590 total medical encounters among athlete and spectator medical services over 19 operational days with 227,847 total visitors (includes spectators, athletes, and workforce). The incidence of medical encounters was 26 per 10,000 visitors. There were 215 medical encounters that were evaluated and treated by a physician in the athlete (69 cases) or spectator (146 cases) medical clinics. The most common diagnoses were related to respiratory infection or respiratory disease. There were 177 patients discharged without follow-up and 26 referred to a medical facility off venue. Six patients were transported to a hospital by ground ambulance. In conclusion, the injuries and illnesses evaluated and treated were consistent with prior studies on medical care at Olympic Games. Although some patients required ground ambulance transport off venue due to injury or illness, there were no critical injuries or illnesses that resulted in death. The level of services available to both athletes and spectators was more than adequate for the injuries and illnesses encountered.

    If changes in animal behavior resulting from direct human disturbance negatively affect the persistence of a given species or population, then these behavioral changes must necessarily lead to reduced demographic performance. We tested for the effects of human disturbance on Olympic marmots (Marmota olympus), a large ground-dwelling squirrel that has disappeared from several areas where recreation levels are high. We assessed the degree to which antipredator and foraging behavior and demographic rates (survival and reproduction) differed between sites with high recreation levels (high use) and those with little or no recreation (low use). Compared with the marmots at low-use sites, marmots at high-use sites displayed significantly reduced responses to human approach, which could be construed as successful accommodation of disturbance or as a decrease in predator awareness. The marmots at high-use sites also looked up more often while foraging, which suggests an increased wariness. Marmots at both types of sites had comparable reproductive and survival rates and were in similar body condition. Until now, the supposition that marmots can adjust their behavior to avoid negative demographic consequences when confronted with heavy tourism has been based on potentially ambiguous behavioral data. Our results support this hypothesis in the case of Olympic marmots and demonstrate the importance of considering demographic data when evaluating the impacts of recreation on animal populations.

    Mass gatherings, such as the Olympic and Paralympic Games, represent an enormous logistical challenge for the host city. Health service planners must deliver routine and emergency services and, in recent Games, health legacy initiatives, for the local and visiting population. However there is little evidence to support their planning decisions. We therefore evaluated the strategic health planning programme for the London 2012 Olympic and Paralympic Games to identify generalisable information for future Games. We thematically analysed data from stakeholder interviews and documents. The data were prospectively collected in three phases, before, during and after the Games. We identified five key themes: (1) Systemic Improvement for example in communications, (2) Effective relationships led to efficiencies and permanent gains, such as new relationships with the private sector (3) Difficult relationships led to inefficiencies, for instance, duplication in testing and exercising emergency scenarios, (4) Tendency to over-estimate demand for care, particularly emergency medicine, and (5) Difficulties establishing a health legacy due to its deprioritisation and lack of vision by the programme team. Enduring improvements which are sustained after the Games are possible, such as the establishment of new and productive partnerships. Relationships must be established early on to avoid duplication, delay and unnecessary expense. There should be greater critical evaluation of the likely demand for health services to reduce the wasting of resources. Finally, if a health legacy is planned, then clear definitions and commitment to its measurement is essential.

    Canoe and kayak paddlers (n = 50 M & 20 F) who competed in the sprint events at the 2000 Olympic Games in Sydney were measured on a battery of 38 anthropometry dimensions prior to competition. The ensuing analysis aimed to identify common physical characteristics that provide these elite paddlers with a competitive advantage. This study demonstrated that participants in Olympic sprint paddling events can be considered homogeneous in shape and physical size; male and female paddlers have SAMs of 1.1 and 1.0 respectively. Compared to other athlete groups, the variance in stature and body mass of paddlers is generally low. Whilst sprint paddlers are not athletes with extreme proportionality profiles, they do possess unique characteristics not commonly observed in the general population. These include a lean body composition (Phantom z-scores for skinfolds range from -1.5 to -2.5 for most sites) with proportionally large upper body girths (z-scores > +1.0 for arm and chest girths), and narrow hips (for males). The morphology of elite paddlers appears to have altered during the past 25 years toward a more compact, robust physique. This trend is especially noticeable for the female competitors.

  6. Exploring Unsteady Sail Propulsion in Olympic Class Sailboats

    2014-11-01

    Unsteady sailing techniques, defined as ``flicking,'' ``roll-tacking'' and ``roll-gybing'' are used by athletes to propel their boats on an Olympic race course faster than using the wind alone. Body weight movements induce unsteady sail motion, increasing driving force and enhancing maneuvering performance. In this research, we explore the dynamics of an Olympic class Laser sailboat equipped with a GPS, IMU, wind sensor, and camera array. The velocity heading of a sailing boat is oriented at an apparent wind angle to the flow. In contrast to classic flapping propulsion, the heaving of the sail section (induced by the sailor's body movement) is not perpendicular to the sail's motion through the air. This leads to an ``exotic heave,'' with components parallel and perpendicular to the incident flow. The characteristic motion is recreated in a towing tank where the vortex structures generated by a representative 2-D sail section are observed, along with a measurement of thrust and lift forces. When combined with turning maneuvers, these heaving sail motions can lead to significant increases in velocity made good, a critical variable used when assessing racing performance.

    The present work is intended to fabricate low-cost flex sensor from conductive carbon paste using direct ink write (DIW) technique. DIW method is one of the additive manufacturing processes, which is capable to deposit a variety of material on a variety of substrates by a different mechanism to feature resolution at a microns level. It is widely used in the electronic industry for fabrication of PCBS and electrodes for different electronic devices. The DIW system in present study extrudes material stored in the syringe barrel through nozzle using compressed air. This mechanism will assist in creating patterns on a variety of substrates. Pneumatic controller is employed to control deposition of material, while computer-controlled X-Y stage is employed to control pattern generation. For effective and control patterning, printing parameters were optimized using Taguchi design optimization technique. The conductive carbon paste is used as ink for pattern generation on flexible PET substrate. Samples of flex sensor having different dimensions are prepared through DIW. The fabricated sensors were used as flexion sensor, and its electrical characteristic was evaluated. The obtained sensors are stable and reliable in performance.

    As the resolutions of Three Dimensional Electron Microscopic reconstructions of biological macromolecules are being improved, there is a need for better fitting and refinement methods at high resolutions and robust approaches for model assessment. Flex-EM/MODELLER has been used for flexible fitting of atomic models in intermediate-to-low resolution density maps of different biological systems. Here, we demonstrate the suitability of the method to successfully refine structures at higher resolutions (2.5-4.5Å) using both simulated and experimental data, including a newly processed map of Apo-GroEL. A hierarchical refinement protocol was adopted where the rigid body definitions are relaxed and atom displacement steps are reduced progressively at successive stages of refinement. For the assessment of local fit, we used the SMOC (segment-based Manders' overlap coefficient) score, while the model quality was checked using the Qmean score. Comparison of SMOC profiles at different stages of refinement helped in detecting regions that are poorly fitted. We also show how initial model errors can have significant impact on the goodness-of-fit. Finally, we discuss the implementation of Flex-EM in the CCP-EM software suite. Copyright © 2016 The Authors.

    Recently, a novel platform has been developed for studying the behavior and physical characteristics of the nematode C. elegans. This is NemaFlex, developed by the Vanapalli group at Texas Tech University to analyze movement and muscular strength of crawling C. elegans. NemaFlex is a microfluidic device consisting of an array of deformable PDMS pillars, with which the C. elegans interacts in the course of moving through the system. Deflection measurements then allow us to calculate the force exerted by the worm via Euler-Bernoulli beam theory. For the procedure to be fully automated a fairly sophisticated software analysis has to be developed in tandem with the physical device. In particular, the usefulness of the force calculations is highly dependent on the accuracy and volume of the deflection measurements, which would be prohibitively time-consuming if carried out by hand/eye. In order to correlate the force results with muscle activations the C. elegans itself has to be tracked simultaneously, and pillar deflections precisely associated with mechanical-contact on the worm's body. Here we will outline the data processing and analysis routines that have been implemented in order to automate the calculation of these forces and muscular activations.

    Transcranial magnetic stimulation (TMS) is able to noninvasively excite neuronal populations due to brief magnetic field pulses. The efficiency and the characteristics of stimulation pulse shapes influence the physiological effect of TMS. However, commercial devices allow only a minimum of control of different pulse shapes. Basically, just sinusoidal and monophasic pulse shapes with fixed pulse widths are available. Only few research groups work on TMS devices with controllable pulse parameters such as pulse shape or pulse width. We describe a novel TMS device with a full-bridge circuit topology incorporating four insulated-gate bipolar transistor (IGBT) modules and one energy storage capacitor to generate arbitrary waveforms. This flexible TMS (flexTMS ) device can generate magnetic pulses which can be adjusted with respect to pulse width, polarity, and intensity. Furthermore, the equipment allows us to set paired pulses with a variable interstimulus interval (ISI) from 0 to 20 ms with a step size of 10  μs. All user-defined pulses can be applied continually with repetition rates up to 30 pulses per second (pps) or, respectively, up to 100 pps in theta burst mode. Offering this variety of flexibility, flexTMS will allow the enhancement of existing TMS paradigms and novel research applications.

    Resolution of ptosis is a key step to the success of many plastic surgery procedures. Ptosis is a manifestation of tissue stretch. Tissue stretch can occur as a result of the natural aging process or health of the patient, or tissue may stretch under added weight or volume, such as when implants are placed. Surgical rejuvenation of ptotic tissues is very effective and results in marked changes in the patient profile yet the tissue that resulted in the need for the procedure first place has not improved and ptosis can recur. Recent developments in long-term resorbable porous materials have provided surgeons with the opportunity to experiment with tissue reinforcement in plastic surgery procedures. These new materials have a low profile, rapid tissue integration, and a long-term strength retention profile. Long-term resorbable scaffolds such as poly-4-hydroxybutyrate (P4HB) natural scaffold (GalaFLEX scaffold, Galatea Surgical, Inc., Lexington, MA) have shown promise for a host of plastic surgery indications. This article presents clinical experience with GalaFLEX for soft tissue reinforcement in three different clinical applications; including the reinforcement of the superficial muscular aponeurotic system (SMAS) in minimally invasive facelift, reinforcement of the skin envelope in mastopexy, and reinforcement of the breast capsule (pocket) in revisional breast surgery. Soft tissue reinforcement has been shown to provide increased mechanical strength as well as improved maintenance of postoperative results. 5 Therapeutic. © 2016 The American Society for Aesthetic Plastic Surgery, Inc.

    A piezoelectric transducer for harvesting energy from ambient mechanical vibrations/strains under pressure condition was developed. The proposed transducer was made of two ring-type piezoelectric stacks, one pair of bow-shaped elastic plates, and one shaft that pre-compresses them. This transducer works in flex-compressive (F-C) mode, which is different from a conventional flex-tensional (F-T) one, to transfer a transversely applied force F into an amplified longitudinal force N pressing against the two piezo-stacks via the two bowshaped elastic plates, generating a large electric voltage output via piezoelectric effect. Our experimental results show that without an electric load, an F-C mode piezo-transducer could generate a maximum electric voltage output of up to 110 Vpp, and with an electric load of 40 κΩ, it a maximum power output of 14.6 mW under an acceleration excitation of 1 g peak-peak at the resonance frequency of 87 Hz. © 2011 IEEE

    Rapid DNA identification is the use of a rugged, field-deployable system to generate short tandem repeat (STR) profiles in law enforcement, military, immigration, and homeland security applications. A performance verification study was conducted on the ANDE Rapid DNA identification system using FlexPlex27, a highly multiplexed, 27 locus assay that generates data for the expanded CODIS core loci and all additional STR loci required for international databasing. The assay contains 23 autosomal loci (D1S1656, D2S1338, D2S441, D3S1358, D5S81, D6S1043, D7S820, D8S1179, D10S1248, D12S391, D13S317, D16S539, D18S51, D19S433, D21S11, D22S1045, FGA, CSF1PO, Penta E, TH01, vWA, TPOX, and SE33), three Y-chromosomal loci (DYS391, DYS576, and DYS570), and Amelogenin. Study results demonstrate that the instrument is reliable, reproducible, accurate, robust, and ready for a large scale, comprehensive developmental validation by NDIS-participating laboratories. The additional loci in the FlexPlex assay allow for improved STR profile sharing globally, increase the power of discrimination for identification matches, and improve the effectiveness of kinship analyses.

    The SWITCH-ON project is an EU FP7 project that started in November 2013 and will run till November 2017. SWITCH-ON stands for Sharing Water-related Information to Tackle Changes in the Hydrosphere for Operational Needs and it addresses the potential of open data. Open water data will be tailored with 14 products for end-users, a spatial information platform and the development of new forms of collaborative research. TU Delft will, among five other universities, help developing these new forms of research. The individual goal of TU Delft is to proof the concept of FLEX-TOPO as introduced by Savenije (2010) and tested in a central European meso-scale catchment by Gharari et al.(2011). The FLEX-TOPO modeling concept makes use of landscape classification based on slope and Height Above the Nearest Drainage (HAND) as defined by Rennó (2008). Gharari et al.(2011) defined for the Wark catchment in the Grand Duchy of Luxembourg three landscape classes: wetland, hillslope and plateau. Areas with low slope and low HAND were defined as wetland, areas with high slope as hillslope and areas with low slope and high HAND as plateau. The distinction between the several landscape units was based on threshold values of slope and HAND. After this classification each of the landscape classes was given its own conceptual model structure. The SWITCH-ON project creates the opportunity to test the FLEX-TOPO concept in catchments all over Europe with different hydrological and climatological characteristics. It can be tested if the classification method as used by Gharari et al. (2011) still holds for other catchments or that new landscape units with different model structures should be created. It can also be discussed if the threshold values for HAND and slope in the Wark catchment can be used all over Europe. Next to that, it can be hypothesized that the different landscape units act different over Europe. For example, does a Mediterranean wetland behave similar to a Scandinavian

    Four flex circuits were tested. They are categorized as: (1) Litchfield narrow; (2) Litchfield wide; (3) Cirexx wide; and (4) Speedy Circuit green. The cross sectional area of copper was calculated from trace resistance measurements. All the flex circuits had an acceptable amount of copper cross section. about 6 e-8 m{sup 2} for all except the Cirexx flex which had 4.5 e-8 m{sup 2}. The thickness of the ribbons was 0.006-inch for the Litchfield and about 0.004-inch for the Cirexx and Speed circuit. The room temperature resistivity ratio (RRR) was measured to be 15 for all the circuits. This was expected and means that the trace material resistivity at helium temperatures is 1/15th of what it is at room temperature. This is good from the standpoint of thermal heat load. Purer copper, with an RRR > 30 would result in an unacceptable heat load. The cryogenic cycling and bending tests to liquid nitrogen proved that both the Cirexx wide and Speedy circuit green were made of acceptable materials. Both Litchfield flex circuits had significant cracking of the coverlay when bent at cold temperatures and are not acceptable. The Litchfield narrow was in bad physical condition to start with and got worse through the testing with many more crazing cracks appearing. The crazing is bad enough that the coverlay began to peel and expose the copper beneath. This candidate is unacceptable. The Litchfield wide started out testing in good condition with no cracks. It ended up with much crazing in the coverlay. Within 1 mm of the edge of the coverlay at the cold end. the copper traces were bulged away from the base material. Traces became nadhered and lifted off of the base material at the ends where the coverlay was not present. Numerous electrical opens (7 out of 24 checked) were found at the end of the testing. Visual inspection of the opens leaves open the possibility that the traces are broken below the coverlay in the cold bend area. Obviously this candidate is unacceptable. The

    Flex sensors can be usefully adopted as mechanical-electrical transducers to measure human joint movements, since their electrical resistance varies proportionally to the angle assumed by the joint under measure. Over time, these sensors have been investigated in terms of mechanical and electrical behavior, but no reports have detailed the possibility of their adoption not just on top but under the human skin of the joint. To this aim, our work investigated in vitro the pyrogenic potential and cytotoxicity of some commercially available flex sensors as a first step toward the necessary requirements regarding their biocompatibility, to predict possible foreign body reactions when used in vivo. Results demonstrated that some specific flex sensors satisfy such requirements. PMID:24988382

    Background Flexed posture commonly increases with age and is related to musculoskeletal impairment and reduced physical performance. The purpose of this clinical study was to systematically compare the effects of a physical activity program that specifically address the flexed posture that marks a certain percentage of elderly individuals with a non specific exercise program for 3 months. Methods Participants were randomly divided into two groups: one followed an Adapted Physical Activity program for flexed posture and the other one completed a non-specific physical activity protocol for the elderly. A multidimensional clinical assessment was performed at baseline and at 3 months including anthropometric data, clinical profile, measures of musculoskeletal impairment and disability. The instrumental assessment of posture was realized using a stereophotogrammetric system and a specific biomechanical model designed to describe the reciprocal position of the body segments on the sagittal plane in a upright posture. Results The Adapted Physical Activity program determined a significant improvement in several key parameters of the multidimensional assessment in comparison to the non-specific protocol: decreased occiput-to-wall distance, greater lower limb range of motion, better flexibility of pectoralis, hamstrings and hip flexor muscles, increased spine extensor muscles strength. Stereophotogrammetric analysis confirmed a reduced protrusion of the head and revealed a reduction in compensative postural adaptations to flexed posture characterized by knee flexion and ankle dorsiflexion in the participants of the specific program. Conclusion The Adapted Physical Activity program for flexed posture significantly improved postural alignment and musculoskeletal impairment of the elderly. The stereophotogrammetric evaluation of posture was useful to measure the global postural alignment and especially to analyse the possible compensatory strategies at lower limbs in flexed

    Dremin, I. M.

    2016-07-01

    Recent experimental data on elastic scattering of high energy protons show that the critical regime has been reached at LHC energies. The approach to criticality is demonstrated by increase of the ratio of elastic to total cross sections from ISR to LHC energies. At LHC it reaches the value which can result in principal change of the character of proton interactions. The treatment of new physics of hollowed toroid-like hadrons requires usage of another branch of the unitarity condition. Its further fate is speculated and interpreted with the help of the unitarity condition in combination with present experimental data. The gedanken experiments to distinguish between different possibilities are proposed.

    2009-09-01

    Gluinos are produced pairwise at the LHC in quark-antiquark and gluon-gluon collisions: qq, gg{yields}g-tildeg-tilde. While the individual polarization of gluinos vanishes in the limit in which the small mass difference between L and R squarks of the first two generations is neglected, nonzero spin-spin correlations are predicted within gluino pairs. If the squark/quark charges in Majorana gluino decays are tagged, the spin correlations have an impact on the energy and angular distributions in reconstructed final states. On the other hand, the gluino polarization in single gluino production in the supersymmetric Compton process gq{yields}g-tildeq-tilde{sub R,L} is predicted to be nonzero, and the polarization affects the final-state distributions in super-Compton events.

  3. Private Higgs at the Lhc

    2013-11-01

    We study the LHC phenomenology of a general class of "Private Higgs" (PH) models, in which fermions obtain their masses from their own Higgs doublets with {O}(1) Yukawa couplings, and the mass hierarchy is translated into a dynamical chain of vacuum expectation values. This is accomplished by introducing a number of light gauge-singlet scalars, the "darkons," some of which could play the role of dark matter. These models allow for substantial modifications to the decays of the lightest Higgs boson, for instance through mixing with TeV-scale PH fields and light darkons: in particular, one could accommodate {O}(10%) flavor-uncorrelated deviations from the SM hf\\bar f vertices with TeV-scale degrees of freedom. We also discuss a new implementation of the PH framework, in which the quark and neutrino mixing angles arise as one-loop corrections to the leading order picture.

    Austin Peay State University's biennial Science ExpOlympics involves competitive events, activities and demonstrations, and a science bowl competition for regional high school students. The purpose of the APSU Science ExpOlympics is threefold: to show all of the attending high school students that the sciences can be fun and interesting, to challenge those high school students who are already interested in the sciences, and to promote APSU as a potential university for graduating high school students. More than 2000 high school students have attended the Science ExpOlympics program since its inception in 1983. The Science ExpOlympics program has been jointly sponsored by the Biology, Chemistry, Geography and Geology, Industrial Technology, Mathematics and Computer Sciences, Physics, and Psychology departments. A list of departments and the events that each has provided is shown below.

    Taking advantage of the natural experiment of the 2008 Beijing Olympics (August 8 to September 24), when air pollution levels decreased by 13% to 60%, the authors assessed whether having ≥1 pregnancy month during the Olympics was associated with decreased risks of hypertensive disorders (HDs) and/or fetal-placental conditions (FPCs). Singleton births to mothers with ≥1 pregnancy month in 2008 or 2009 (N = 56,155) were included. Using generalized additive models, the authors estimated the risk of HDs and FPCs associated with (1) the 2008 Olympics compared with the same dates in 2009, and (2) increased mean ambient PM10 (particulate matter with an aerodynamic diameter <10 μm), NO2 (nitrogen dioxide), and SO2 (sulfur dioxide) concentrations during each trimester. However, no association between HDs or FPCs and having any trimester during the 2008 Olympic period was found. This may, in part, be due to a small number of pregnancy complications in this population.

  7. Proscribed drugs at the Olympic Games: permitted use and misuse (doping) by athletes.

    Athletes have always sought to outperform their competitors and regrettably some have resorted to misuse of drugs or doping to achieve this. Stimulants were taken by the first Olympic athletes to be disqualified in 1972. Although undetectable until 1975, from the 1950s androgenic anabolic steroids were administered for increased strength and power followed in the 1990s by erythropoietin for enhanced endurance. Both are highly effective doping agents. As analytical science validated improved techniques to identify these drugs, Olympic athletes, including many medallists were caught and disqualified. When the International Olympic Committee (IOC) prohibited beta blockers (beneficial in shooting), diuretics (assist weight classified athletes) and glucocorticosteroids, some athletes with genuine medical conditions were denied legitimate medical therapy. To overcome this, in 1992 the IOC introduced a system known now as Therapeutic Use Exemption (TUE). This paper discusses Olympic athletes who have been known to dope at past Games and some medical indications and pitfalls in the TUE process.

    A woman in her 80s with an infrarenal aortic aneurysm was scheduled for endovascular aortic repair (EVAR). The aneurysm had a severely angulated neck (SAN), and the Zenith Flex device was selected. Completion angiography showed migration of the main body resulting in right renal artery stenosis. A Palmaz genesis was placed across the renal orifice. The patient had no renal dysfunction and was discharged 7 days after EVAR. If Zenith Flex devices are used for a SAN, it is necessary to consider not only the position of the renal artery but also the appropriate position of the stent-graft. PMID:27738470

    Objectives The authors examined the impact of exposure to the 2010 Winter Olympics time period on outcomes measuring disruption of local sex work environments in Vancouver, Canada. Methods The authors conducted a before-and-after study, using multivariable logistic regression, to assess the relationship between exposure to the Olympics period (19 January–14 March 2010) versus the post-Olympics period (1 April–1 July 2010) and outcomes. Results This study included 207 youth (14+ years) and adult sex workers (SWs) (Olympics: n=107; post-Olympics: n=100). SWs in the two periods were statistically similar, with an overall median age of 33 years (IQR: 28–40), and 106 (51.2%) of indigenous ancestry or ethnic minority. In separate multivariable logistic regression models, the Olympics period remained statistically significantly associated with perceived heightened police harassment of SWs without arrest (adjusted ORs (AOR): 3.95, 95% CIs 1.92 to 8.14), decreased availability of clients (AOR: 1.97, 95% CIs 1.11 to 3.48) and increased difficulty meeting clients due to road closures/construction (AOR: 7.68, 95% CIs 2.46 to 23.98). There were no significantly increased odds in perceived reports of new (0.999), youth (0.536) or trafficked SWs (zero reports) in the Olympic period. Conclusions To reduce potential adverse public health impacts of enhanced police harassment and displacement of local sex work markets, results suggest that evidence-based public health strategies need to be adopted for host cities of future events (eg, the London 2012 Olympic Games), such as the removal of criminal sanctions targeting sex work and the piloting and rigorous evaluation of safer indoor work spaces.

    The aim of this study was to describe the training routines used by judo athletes and their perception concerning the relevance, effort made, concentration needed, and pleasure obtained during the training sessions conducted 6 months before their Olympic participation and to compare with medal winners and other competitors in these aspects. Sixty-one Olympic Brazilian judo athletes (men = 39; women = 22), representing 66.3% of all Brazilian participants in this Olympic sport (from 1964 to 2008), including 10 medal winners (9 men and 1 woman) answered a questionnaire concerning their training routines. Mann-Whitney and Student's t-test for independent samples were used. Judo medalists and nonmedalists in the Olympic Games did not differ in: (a) the age when they started to practice and to compete in judo, (b) the age when they competed in the Olympic Games, (c) hours of training per week and per training session and the number of training sessions per day in their preparation for this event, (d) frequency and time spent for performing judo-specific and general exercises and their perceived relevance, effort, pleasure, and concentration for these activities performed during the preparation for the Olympic Games. The only differences found were the groundwork (ne-waza) randori practice, which was less frequently performed by medal winners, and perceived relevance attributed to this activity, which was considered less relevant by the medal winners compared with nonmedal winners. Thus, judo Olympic medal winners and nonmedalists did not differ in many training aspects in the final phase of their preparation to the Olympic Games.

    The US HEP community has identified the exploitation of physics opportunities at the High Luminosity-LHC (HL-LHC) as the highest near-term priority. Thanks to multi-year R&D programs, US National Laboratories and Universities have taken the leadership in the development of technical solutions to increase the LHC luminosity, enabling the HL-LHC Project and uniquely positioning this country to make critical contributions to the LHC luminosity upgrade. This talk will describe the shaping of the US Program to contribute in the next decade to HL-LHC through newly developed technologies such as Nb3Sn focusing magnets or superconducting crab cavities. The experience gained through the execution of the HL-LHC Project in the US will constitute a pool of knowledge and capabilities allowing further developments in the future. Opportunities for US participations in proposed hadron colliders, such as a possible High Energy-LHC (HE-LHC), will be described as well.

    2016-01-01

    The objective of this study was to determine if the Pacific marten (Martes caurina) still occurs on the Olympic Peninsula in Washington State. We reviewed recent records of marten observations on the Olympic Peninsula since 1998, and conducted new surveys in undersampled regions of the Olympic Peninsula during summer, 2016. We reviewed evidence of fisher presence from 6 previously reported studies of carnivore distribution and presence on the Olympic Peninsula and conducted new surveys in previously undersampled areas of the Peninsula. We documented five highly reliable records of marten observations on the Pensula since 1988. Further, we established 197 camera stations in search of martens, amassing a total of 17,897 camera-nights of survey efforts in previously undersampled regions. We documented presence of one additional marten during summer 2016. This marten, however, was close to a marten detected in 2015, so it was not clear if it represented a different marten. We concluded that five to six martens have been verified present on the Olympic Peninsula since 1988. Pacific martens appear to be very limited in distribution and at critically low numbers throughout much of their former range on the Olympic Peninsula.

    This article outlines the process of preparation of an anti-doping laboratory in view of the activities to be performed on the occasion of the Olympic Games, focusing in particular on the accreditation requirements of the World Anti-Doping Agency (WADA) and ISO/IEC 17025, as well as on the additional obligations required by the International Olympic Committee, which is the testing authority responsible for the anti-doping activities at the Olympics. Due to the elevated workload expected on the occasion of the Olympic Games, the designated anti-doping laboratory needs to increase its analytical capacity (samples processed/time) and capability by increasing the laboratory's resources in terms of space, instrumentation and personnel. Two representative cases, one related to the Winter Olympic Games (Torino 2006) and one related to the Summer Olympic Games (Beijing 2008), are presented in detail, in order to discuss the main aspects of compliance with both the WADA and ISO/IEC 17025 accreditation requirements.

  16. Have the Olympic Games become more migratory? A comparative historical perspective.

    It is often believed that the Olympic Games have become more migratory. The number of Olympic athletes representing countries in which they weren't born is thought to be on the rise. It should, however, be noted that migration in the context of sports is hardly a new phenomenon. In this paper we hypothesise that, as a reflection of global migration patterns and trends, the number of foreign-born Olympians hasn't necessarily increased in all countries. Furthermore, it was expected that the direction of Olympic migration has changed and that foreign athletes increasingly come from a more diverse palette of countries. We conducted an analysis of approximately 40,000 participants from 11 countries who participated in the Summer Games between 1948 and 2012. The selected countries have different histories of migration and cover the distinction between 'nations of immigrants' (Australia, Canada, United States), 'countries of immigration' (France, Great Britain, Netherlands, Sweden), 'latecomers to immigration' (Italy, Spain) and, what we coin, 'former countries of immigration' (Argentina, Brazil). We conclude that the Olympic Games indeed have not become inherently more migratory. Rather, the direction of Olympic migration has changed and most teams have become more diverse. Olympic migration is thus primarily a reflection of global migration patterns instead of a discontinuity with the past.

    Preparing a national team for success at major sporting competitions such as the Olympic Games has become a systematic and multi-faceted activity. Sports nutrition contributes to this success via strategic nutritional interventions that optimize the outcomes from both the training process and the competitive event. This review summarizes the National Nutrition Programs involved with the 2012 London Olympic Games preparation of the Australian, British and American sports systems from the viewpoints of three key agencies: the Australian Institute of Sport, the English Institute of Sport and the United States Olympic Committee. Aspects include development of a nutrition network involving appropriately qualified sports dietitians/nutritionists within a multi-disciplinary team, recognition of continual updates in sports nutrition knowledge, and a systematic approach to service delivery, education and research within the athlete's daily training environment. Issues of clinical nutrition support must often be integrated into the performance nutrition matrix. Food service plays an important role in the achievement of nutrition goals during the Olympic Games, both through the efforts of the Athlete Dining Hall and catering activities of the host Olympic Games Organizing Committees as well as adjunct facilities often provided by National Olympic Committees for their own athletes.

    Very little data on the provision of imaging services at the summer Olympic Games have been published before. With 7.9 million Euros (£6.6 million, US$11 million) invested into setting up the imaging equipment at the purpose-built polyclinics for London 2012 summer Olympics, an ideal opportunity was presented to study the demand and distribution of workload on imaging services at the games. Imaging services within polyclinics, London 2012 summer Olympic Games. To analyse the demand and distribution of workload on radiology services at the London 2012 summer Olympic Games. Data on radiological investigations performed at London 2012 summer Olympic Games were retrieved from Radiology Information System-picture archiving communication system, ATOS medical encounter database and analysed. 1711 diagnostic and interventional procedures were performed at the Stratford Polyclinic within the main games village. Of these 48.8% were MRI scans, 20.2% were diagnostic ultrasound examinations, 23.6% were plain radiographs, 2.9% were CT scans and interventional procedures accounted for 4.3%. Nearly 75% of imaging was performed on athletes while less than 5% of the services were utilised by the workforce. Demand on radiology services peaked during week 2 of the games. Imaging played a substantial role in providing medical services at the London 2012 summer Olympics.

    This study examined the relationships between salivary testosterone (Sal-T) and cortisol (Sal-C) concentrations and training performance in Olympic weightlifters. Four male and four female Olympic weightlifters each provided saliva samples before and after four workouts during a four-week training period. Training involved the same three exercises; snatch, clean and jerk, and front squat with the one repetition maximum (1RM) calculated for each exercise during each workout. Significant (P < 0.05-0.01) training improvements in 1RM performance (4.0-5.2%) were noted during the snatch and clean and jerk exercises, along with the Olympic total lift. For male participants only, the pre-workout concentrations of Sal T were significantly (P < 0.05-0.01) correlated with the snatch (r = 0.70) and clean and jerk 1RM (r = 0.62), and the Olympic total lift (r = 0.66). A short period of training improved the 1RM performance of Olympic weightlifters in two exercises (snatch and clean and jerk) and the Olympic total. For male participants, their Sal-T concentrations before each workout was also related to 1RM performance during these exercises, thereby highlighting one possible short-term causative mechanism. Limitations of this study include the short duration of hormonal monitoring, the limited number of workouts assessed and the small number of participants recruited. Also, correlations between the outcome variables still only reflect casual associations.

Considering both neutralino and gravitino LSPs, we compare our results with simplified model exclusion limits and describe important cases where the pMSSM results differ significantly from the simplified model descriptions. We also consider models that are poorly constrained by LHC data because of unusual decay topologies and/or displaced decays, and discuss ways to improve the LHC sensitivity in these scenarios. Finally, motivated by naturalness, we examine the sensitivity of current searches to models with light stops and to a specialized set of models with fine-tuning better than 1%. We show that the 14 TeV LHC will be a very powerful probe of natural pMSSM models.

    Gauge mediated SUSY breaking (GMSB) is a promising class of supersymmetric models that automatically satisfies the precision constraints. Prior work of Meade, Seiberg and Shih in 2008 established the full, model-independent parameter space of GMSB, which they called "General Gauge Mediation" (GGM). During the first half of 2010-2015, Shih and his collaborators thoroughly explored the parameter space of GGM and established many well-motivated benchmark models for use by the experimentalists at the LHC. Through their work, the current constraints on GGM from LEP, the Tevatron and the LHC were fully elucidated, together with the possible collider signatures of GMSB at the LHC. This ensured that the full discovery potential for GGM could be completely realized at the LHC.

    2015-03-01

    INTRODUCTION: The ABC® D-Flex Probe utilizes argon beam coagulation (ABC) technology to achieve hemostasis during minimally invasive surgery. A handle on the probe allows for integration with robotic surgical systems and introduces ABC to the robotic toolbox. To better understand the utility of D-Flex, this study compares the performance of the D-Flex probe to an existing ABC laparoscopic probe through ex vivo tissue analysis. METHODS: Comparisons were performed to determine the effect of four parameters: ABC device, tissue type, activation duration, and distance from tissue. Ten ABC D-Flex probes were used to create 30 burn samples for each comparison. Ex vivo bovine liver and porcine muscle were used as tissue models. The area and depth of each burn was measured using a light microscope. The resulting dimensional data was used to correlate tissue effect with each variable. RESULTS: D-Flex created burns which were smaller in surface area than the laparoscopic probe at all power levels. Additionally, D-Flex achieved thermal penetration levels equivalent to the laparoscopic probe. CONCLUSION: D-Flex implements a small 7F geometry which creates a more focused beam. When used with robotic precision, quick localized superficial hemostasis can be achieved with minimal collateral damage. Additionally, D-Flex achieved equivalent thermal penetration levels at lower power and argon flow-rate settings than the laparoscopic probe.

    The > 10,000 million tonne Olympic Dam Cu-Au-U-Ag deposit, (eastern Gawler Craton, South Australia) is one of the largest orebodies in the World. The deposit is hosted within the Olympic Dam Breccia Complex, placed at the centre of, and resulting from multiple brecciation and Fe-metasomatism of the Roxby Downs Granite (RDG). The latter is part of a larger batholith emplaced at 1.6 Ga. Apatite petrography and chemistry were studied in non-mineralised RDG and coeval granitoids and dolerites, as well as in mineralised RDG from deep (> 2 km) and distal (2.7 km to NE) locations. In both latter cases, although the mineralisation corresponds to the same, early chalcopyrite-pyrite-magnetite ± hematite stage identified in the outer and deeper zones of the deposit itself, the character of granite alteration differs: sericite-chlorite alteration with all feldspar replaced in the deep location; and red-stained K-feldspar on top of prevailing albitization in the distal location. Close-to end-member fluorapatite is a key accessory mineral in all igneous rocks and a common product of early hydrothermal alteration within mineralised granite. Variations in habit, morphology and textures correlate with chemical trends expressed as evolving Cl/F ratios, and concentrations of REE + Y (hereafter REY), Sr, Mn, S, Si and Na. Magmatic apatite is unzoned in the dolerite but features core to REY-enriched rim zonation in the granitoids. Increases in Cl- and Sr-contents correlate with rock basicity. Calculation of Cl in the vapour phase relative to melt at the apatite saturation temperature for zoned apatite in the RDG shows higher values for grains with inclusion-rich cores associated with mafic enclaves, concordant with assimilation of exotic material during magma crystallisation. Hydrothermal alteration of magmatic apatite is most varied in the dolerite where interaction with fluids is expressed as subtle changes in Cl- versus F- and REY-enrichment, and most importantly, S-enrichment in

    Understanding the motivations for people to volunteer with the management and execution of major sporting events is important for the recruitment and retention of the volunteers. This research investigated volunteer motivations at the first National Special Olympics held in Ames, Iowa, USA in July 2006. A total of 289 participants completed the 28 item Special Event Volunteer Motivation Scale. The top motivations related to the purposive incentives of wanting to help make the event a success and to do something good for the community. Factor analysis revealed a five-factor model, with the altruistic factor (purposive) being the most important. A MANCOVA was also used to compare subjects using both gender and experience as independent variables. Small but significant differences in motivation were observed.

    Six members of the Irish Olympic Road Cycling Squad underwent a comprehensive medical, nutritional, psychological and biochemical assessment in January 1983. They were given specific medical and dietary recommendations and were reassessed in January 1984 after a period spanning the competitive racing season. The cyclists' diets at both sessions were comparable and generally conformed with recommended daily intakes. Supplementary ingestion was unnecessary to attain recommended daily intakes of vitamins. Serum levels of HDL-cholesterol increased and triglyceride decreased during the period of the study. The squad had characteristics indicating traits of self-sufficiency, toughness and practical mindedness. At the second assessment there was evidence of heightened ambition and competitiveness and an improvement in mood states with reduced ratings for confusion and tension.

    The Olympic sport of skeleton involves an athlete riding a small sled face first down a bobsled track at speeds up to 130 km/hr. In these races, the difference between gold and missing the medal stand altogether can be hundredths of a second per run. As such, reducing aerodynamic drag through proper body positioning is of first order importance. To better study the flow behavior and to improve the performance of the athletes, we constructed a static force balance system on a mock section of a bobsled track. Athlete and the sled are placed on the force balance system which is positioned at the exit of an open loop wind tunnel. Simultaneous drag force and DPIV velocity field measurements were made along with video recordings of body position to aid the athletes in determining their optimal aerodynamic body position.

    To analyze the incidence and the variety of diseases at Olympic competition venues, non-competition venues and special control zones through the statistical analysis of medical data of Beijing 2008 Olympic Games. The proportions of people contracting diseases among different groups, i.e. non-registered people, athletes, staff, media, VIPs and others were analyzed. At different venues the incidence proportions of diseases in cardiovascular system, stomatology, gastroenterology, ENT, respiratory system, surgery, neuropsychiatry, physical injury, genitourinary system and burns were calculated. And the disease spectrum and incidence proportions at specified venues were analyzed. 1. Among all groups of people involved in Beijing 2008 Olympic Games, the proportion of disease-contracting staff was the highest (44.83%) while that of VIPs the lowest (4.76%) so that the incidence proportions were different among different groups of people. 2. Chi2 = 2427.803, (P < 0.01) The statistical analysis of disease distribution indicates that people at different venues might contract different diseases. 3. The proportions of disease-contracting people at competition venues, non-competition venues, training venues and special control zones were 36.08%, 50.66%, 2.31% and 10.96% respectively, which was related to the number of people at a particular venue. 4. The incidence proportion of surgical diseases was quite high, especially maxillofacial and orthopedic diseases (orthopedic trauma) ranking as top 2 at all venues. Thus there should be surgeons at every venue, especially maxillofacial (for hockey) and orthopedic surgeons. At training venues, the number of people contracting E.N.T. diseases ranked No. 1, chi2 = 74.859 (P < 0.01), compared with that of non-competition venues at No. 2. So the incidence proportion of ENT diseases was higher at training venues than at non-competition venues. The number of people contracting respiratory diseases was the largest in special control zones and

    With the translocation and release of 90 fishers (Pekania pennanti) from British Columbia to Olympic National Park during 2008–2010, the National Park Service and Washington Department of Fish and Wildlife accomplished the first phase of fisher restoration in Washington State. Beginning in 2013, we initiated a new research project to determine the current status of fishers on Washington’s Olympic Peninsula 3–5 years after the releases and evaluate the short-term success of the restoration program. Objectives of the study are to determine the current distribution of fishers and proportion of the recovery area that is currently occupied by fishers, determine several genetic characteristics of the reintroduced population, and determine reproductive success of the founding animals through genetic studies. During 2014, we continued working with a broad coalition of cooperating agencies, tribes, and nongovernmental organizations (NGO) to collect data on fisher distribution and genetics using noninvasive sampling methods. The primary sampling frame consisted of 157 24-square-kilometer hexagons (hexes) distributed across all major land ownerships within the Olympic Peninsula target survey area. In 2014 we expanded the study by adding 58 more hexes to an expanded study area in response to incidental fisher observations outside of the target area obtained in 2013; 49 hexes were added south and 9 to the east of the target area. During 2014, federal, state, tribal and NGO biologists and volunteers established three baited motion-sensing camera stations, paired with hair snaring devices, in 80 hexes; 69 in the targeted area 11 in the expansion areas. Each paired camera/hair station was left in place for approximately 6 weeks, with three checks on 2-week intervals. We documented fisher presence in 5 of the 80 hexagons, and identified 5 different fishers through a combination of microsatellite DNA analyses and camera detections. All fisher detections were in the target area

    Detailed accounts of the training programs followed by today's elite triathletes are lacking in the sport-science literature. This study reports on the training program of a world-class female triathlete preparing to compete in the London 2012 Olympic Games. Over 50 wk, she performed 796 sessions (303 swim, 194 bike, 254 run, 45 strength training), ie, 16 ± 4 sessions/wk (mean ± SD). Swim, bike, and run training volumes were, respectively, 1230 km (25 ± 8 km/wk), 427 h (9 ± 3 h/wk), and 250 h (5 ± 2 h/wk). Training tasks were categorized and prescribed based on heart-rate values and/or speeds and power outputs associated with different blood lactate concentrations. Training performed at intensities below her individual lactate threshold (ILT), between the ILT and the onset of blood lactate accumulation (OBLA), and above the OBLA for swim were 74% ± 6%, 16% ± 2%, 10% ± 2%; bike 88% ± 3%, 10% ± 1%, 2.1% ± 0.2%; and run 85% ± 2%, 8.0% ± 0.3%, 6.7% ± 0.3%. Training organization was adapted to the busy competition calendar (18 events, of which 8 were Olympic-distance triathlons) and continuously responded to emerging information. Training volumes were 35-80% higher than those previously reported for elite male and female triathletes, but training intensity and tapering strategies successfully followed recommended best practice for endurance athletes. This triathlete placed 7th in London 2012, and her world ranking improved from 14th to 8th at the end of 2012.

    Discoveries at the LHC will soon set the physics agenda for future colliders. This report of a CERN Theory Institute includes the summaries of Working Groups that reviewed the physics goals and prospects of LHC running with 10 to 300 fb{sup -1} of integrated luminosity, of the proposed sLHC luminosity upgrade, of the ILC, of CLIC, of the LHeC and of a muon collider. The four Working Groups considered possible scenarios for the first 10 fb{sup -1} of data at the LHC in which (i) a state with properties that are compatible with a Higgs boson is discovered, (ii) no such state is discovered either because the Higgs properties are such that it is difficult to detect or because no Higgs boson exists, (iii) a missing-energy signal beyond the Standard Model is discovered as in some supersymmetric models, and (iv) some other exotic signature of new physics is discovered. In the contexts of these scenarios, theWorking Groups reviewed the capabilities of the future colliders to study in more detail whatever new physics may be discovered by the LHC. Their reports provide the particle physics community with some tools for reviewing the scientific priorities for future colliders after the LHC produces its first harvest of new physics from multi-TeV collisions.

  16. Introduction to the HL-LHC Project

    The Large Hadron Collider (LHC) is one of largest scientific instruments ever built. It has been exploring the new energy frontier since 2010, gathering a global user community of 7,000 scientists. To extend its discovery potential, the LHC will need a major upgrade in the 2020s to increase its luminosity (rate of collisions) by a factor of five beyond its design value and the integrated luminosity by a factor of ten. As a highly complex and optimized machine, such an upgrade of the LHC must be carefully studied and requires about ten years to implement. The novel machine configuration, called High Luminosity LHC (HL-LHC), will rely on a number of key innovative technologies, representing exceptional technological challenges, such as cutting-edge 11-12 tesla superconducting magnets, very compact superconducting cavities for beam rotation with ultra-precise phase control, new technology for beam collimation and 300-meter-long high-power superconducting links with negligible energy dissipation. HL-LHC federates efforts and R&D of a large community in Europe, in the US and in Japan, which will facilitate the implementation of the construction phase as a global project.

    Since 1960’s, particle colliders have been in the forefront of particle physics, 29 total have been built and operated, 7 are in operation now. At present the near term US, European and international strategies of the particle physics community are centered on full exploitation of the physics potential of the Large Hadron Collider (LHC) through its high-luminosity upgrade (HL-LHC). The future of the world-wide HEP community critically depends on the feasibility of possible post-LHC colliders. The concept of the feasibility is complex and includes at least three factors: feasibility of energy, feasibility of luminosity and feasibility of cost. Here we overview all current options for post-LHC colliders from such perspective (ILC, CLIC, Muon Collider, plasma colliders, CEPC, FCC, HE-LHC) and discuss major challenges and accelerator R&D required to demonstrate feasibility of an energy frontier accelerator facility following the LHC. We conclude by taking a look into ultimate energy reach accelerators based on plasmas and crystals, and discussion on the perspectives for the far future of the accelerator-based particle physics. This paper largely follows previous study [1] and the presenta ion given at the ICHEP’2016 conference in Chicago [2].

    Background The use of geographical information system (GIS) technologies in public health surveillance is gradually gaining momentum around the world and many applications have already been reported in the literature. In this study, GIS technology was used to help county departments of Public Health to implement environmental health surveillance for the Athens 2004 Olympic and Para Olympic Games. Methods In order to assess the workload in each Olympic county, 19 registry forms and 17 standardized inspection forms were developed to register and inspect environmental health items requiring inspection (Hotels, restaurants, swimming pools, water supply system etc), respectively. Furthermore, related databases were created using Epi Info 2002 and a geographical information system (GIS) were used to implement an integrated Environmental Health inspection program. The project was conducted in Athens by the Olympic Planning Unit (OPU) of the National School of Public Health, in close cooperation with the Ministry of Health and Social Solidarity and the corresponding departments of Public Health in all municipalities that were scheduled to host events during the Athens 2004 Olympic and Para Olympic games. Results A total of 44,741 premises of environmental health interest were geocoded into GIS databases and several electronic maps were developed. Using such maps in association with specific criteria, we first identified the maximum workload required to execute environmental health inspections in all premises within the eleven Olympic County Departments of Public Health. Six different scenarios were created for each county, based on devised algorithms in order to design the most effective and realistic inspection program using the available inspectors from each municipality. Furthermore, GIS applications were used to organize the daily inspection program for the Olympic games, provide coloured displays of the inspection results and link those results with the public health

    Aerocoat AR-7 is a coating that has been used to protect stainless steel flex hoses at NASA's Kennedy Space Center launch complex and hydraulic lines of the mobile launch platform (MLP). This coating has great corrosion control performance and low temperature application. AR-7 was developed by NASA and produced exclusively for NASA but its production has been discontinued due to its high content of volatile organic compounds (VOC) and significant environmental impact. The purpose of this project was to select and evaluate candidate coatings to find a replacement coating that is more environmentally friendly, with similar properties to AR-7. No coatings were identified that perform the same as AR-7 in all areas. Candidate coatings failed in comparison to AR-7 in salt fog, beachside atmospheric exposure, pencil hardness, Mandrel bend, chemical compatibility, adhesion, and ease of application tests. However, two coatings were selected for further evaluation.

    Various vacuum jacketed cryogenic supply lines at the Shuttle launch site use convoluted flexible expansion joints. The atmosphere at the launch site has a very high salt content, and during a launch fuel combustion products include hydrochloric acid. This extremely corrosive environment has caused pitting corrosion failure in the flex hoses, which were made out of 304L stainless steel. A search was done to find a more corrosion resistant replacement material. Nineteen metal alloys were tested. Tests which were performed include electrochemical corrosion testing, accelerated corrosion testing in a salt fog chamber, long term exposure at the beach corrosion testing site, and pitting corrosion tests in ferric chloride solution. Based on the results, the most corrosion resistant alloys were found to be, in order, Hastelloy C-22, Inconel 625, Hastelloy C-276, Hastelloy C-4, and Inco Alloy G-3. Of these top five alloys, the Hastelloy C-22 stands out as being the best of the alloys tested.

    Flow diversion for the management of intracranial aneurysms represents a paradigm shift in how aneurysms are managed. The Pipeline embolization device (PED) is, to date, the only flow diverter approved for use in the USA by the Food and Drug Administration. Limitations and complications with new treatment strategies are inevitable, and with the PED there have been reports of complications, most commonly with challenging deployments. Once deployment has been initiated, the device is 'one-way'; it can only be deployed further or removed. Yet, situations arise in which the ability to recapture or reposition the device would be advantageous. A second-generation Pipeline has been developed that addresses these concerns. We report the first use in North America of this second-generation Pipeline device: the Pipeline Flex. We discuss our rationale for using the device, our impressions of its operation, and the relevant literature concerning the current state of flow diversion.

    The increasing prevalence of low power consuming electronics brings greater potential to mobile energy harvesting devices as a possible power source. A new piezoelectric energy harvesting device, called the piezoelectric flex transducer (PFT), is presented and developed. A Finite Element Model (FEM) was developed to design and analyse the PFT. The PFT consists of a piezoelectric element sandwiched between substrate layers and metal endcaps that are able to amplify the axial force on the piezoelectric element. Based on the concept of the Cymbal transducer, the PFT can withstand higher forces, was retrofitted into a shoe and used to power a wireless sensor module whilst the subject with a body weight of 760N was wearing the shoe and ran at 3.1mph (1.4HZ on shoe), the PFT produced an average maximum power of 2.5mW (over 2MΩ load).

Results from a first DoE indicated large panel voids could be eliminated by removing the pre-HASL cleaning. It also revealed eliminating the pre-HASL bake would not be detrimental when using a hard press pad lamination stackup. A second DoE indicated a reduction in hard press pad stackup lamination pressure reduced panel stretch in the y axis approximately 70%. A third DoE illustrated increasing the pre-HASL bake temperature could reduce delamination/solder wicking when using a soft press pad lamination stackup.

    Hunting spiders are well adapted to fast locomotion. Space saving hydraulic leg extension enables leg segments, which consist almost soley of flexor muscles. As a result, the muscle cross sectional area is high despite slender legs. Considering these morphological features in context with the spider's segmented C-shaped legs, these specifics might influence the spider's muscle properties. Moreover, these properties have to be known for modeling of spider locomotion. Cupiennius salei (n = 5) were fixed in a metal frame allowing exclusive flexion of the tibia-metatarsus joint of the second leg (counted from anterior). Its flexing muscles were stimulated supramaximally using needle electrodes. Accounting for the joint geometry, the force-length and the force-velocity relationships were determined. The spider muscles produce 0.07 N cm maximum isometric moment (corresponding to 25 N/cm(2) maximum stress) at 160 degrees tibia-metatarsus joint angle. When overextended to the dorsal limit at approximately 200 degrees , the maximum isometric moments decrease to 72%, and, when flexed to the ventral hinge stop at 85 degrees , they drop to 11%. The force-velocity relation shows the typical hyperbolic shape. The mean maximum shortening velocity is 5.7 optimum muscle lengths per second and the mean curvature (a/F (iso)) of the Hill-function is 0.34. The spider muscle's properties which were determined are similar to those of other species acting as motors during locomotion (working range, curvature of Hill hyperbola, peak power at the preferred speeds), but they are relatively slow. In conjunction with the low mechanical advantage (muscle lever/load arm), the arrangement of three considerably actuated joints in series may nonetheless enable high locomotion velocities.

    Aims The use of biodegradable-polymer drug-eluting stents has been shown to provide favorable results when compared with durable polymer drug-eluting stents and long-term follow up data have recently shown significant reductions in terms of very late stent thrombosis. Aim of the present study was to assess the safety and efficacy profile of a novel biodegradable polymer DES, the Yukon Choice Flex sirolimus-eluting stent. Methods We report here the one-year clinical outcomes associated with the use of the Yukon Choice Flex sirolimus-eluting stent in an all-comers patient population. The present stent represents a further refinement of the stent platform tested in the ISAR TEST 3 and 4 randomized clinical trials. A total of 778 consecutive patients undergoing implantation of this stent were enrolled in the present observational study and prospectively followed for one year. Results The use of the Yukon Choice Flex stent in a patient population with complex coronary lesion morphology was associated with optimal immediate angiographic results. At one year follow up the rates of death, myocardial infarction, definite stent thrombosis and ischemia-driven target lesion revascularization were respectively 2.4%, 1.9%, 0.3% and 11.3%. Conclusions The use of the sirolimus-eluting biodegradable polymer Yukon Choice Flex stent in an all-comers population of patients with complex coronary artery disease is associated with a favorable safety and efficacy profile up to one year follow up.

    Vertebral fractures, an increased thoracic kyphosis and a flexed posture are associated with falls. However, this was not confirmed in prospective studies. We performed a prospective cohort study to investigate the association between vertebral fractures, increased thoracic kyphosis and/or flexed posture with future fall incidents in older adults within the next year. Patients were recruited at a geriatric outpatient clinic. Vertebral fractures were evaluated on lateral radiographs of the spine with the semi-quantitative method of Genant; the degree of thoracic kyphosis was assessed with the Cobb angle. The occiput-to-wall distance was used to determine a flexed posture. Self-reported falls were prospectively registered by monthly phone contact for the duration of 12 months. Fifty-one older adults were included; mean age was 79 years (SD = 4.8). An increased thoracic kyphosis was independently associated with future falls (OR 2.13; 95% CI 1.10-4.51). Prevalent vertebral fractures had a trend towards significancy (OR 3.67; 95% CI 0.85-15.9). A flexed posture was not significantly associated with future falls. Older adults with an increased thoracic kyphosis are more likely to fall within the next year. We suggest clinical attention for underlying causes. Because patients with increased thoracic curvature of the spine might have underlying osteoporotic vertebral fractures, clinicians should be aware of the risk of a new fracture.

    The roughest part of the ride may be over for U.S. physicists who want to participate in the Large Hadron Collider (LHC), the $5 billion accelerator planned for CERN in Geneva. They have found themselves on a political roller coaster for the past few months. This week, U.S. and European negotiators were putting the final touches on a revamped agreement that should pave the way for the United States to help pay for construction of the accelerator and its two main detectors, and guarantee U.S. scientists a role in research on the machine. The trouble began in March, when Representative Joe Barton (R-TX) declared war on a proposed $530 million U.S. contribution to the new facility, slated for completion in 2005. Barton and many other members of Congress were still smarting from what they said was a lack of European support for the canceled Superconducting Super Collider that was being built in Barton`s backyard. Representative James Sensenbrenner (R-WI), who chairs the House Science Committee, led the charge to alter a draft agreement initialed this winter by Department of Energy (DOE) and CERN officials that spelled out the details of U.S. participation. After hurried negotiations, both sides have sharpened the agreement to address the lawmakers` concerns. The new deal, says Energy Secretary Federico Pena, {open_quotes}has made that project even better.{close_quotes}

    We discuss the main signatures of the Bilepton Model at the Large Hadron Collider, focusing on its gauge boson sector. The model is characterised by five additional gauge bosons, four charged and one neutral, beyond those of the Standard Model, plus three exotic quarks. The latter turn into ordinary quarks with the emission of bilepton doublets (Y++ ,Y+) and (Y- ,Y-) of lepton number L = - 2 and L = + 2 respectively, with the doubly-charged bileptons decaying into same-sign lepton pairs. We perform a phenomenological analysis investigating processes with two doubly-charged bileptons and two jets at the LHC and find that, setting suitable cuts on pseudorapidities and transverse momenta of final-states jets and leptons, the model yields a visible signal and the main Standard Model backgrounds can be suppressed. Compared to previous studies, our investigation is based on a full Monte Carlo implementation of the model and accounts for parton showers, hadronization and an actual jet-clustering algorithm for both signal and Standard Model background, thus providing an optimal framework for an actual experimental search.

    Knowing the charge of the parton initiating a light-quark jet could be extremely useful both for testing aspects of the standard model and for characterizing potential beyond-the-standard-model signals. We show that despite the complications of hadronization and out-of-jet radiation such as pileup, a weighted sum of the charges of a jet's constituents can be used at the LHC to distinguish among jets with different charges. Potential applications include measuring electroweak quantum numbers of hadronically decaying resonances or supersymmetric particles, as well as standard model tests, such as jet charge in dijet events or in hadronically decaying W bosons in tt[over ¯] events. We develop a systematically improvable method to calculate moments of these charge distributions by combining multihadron fragmentation functions with perturbative jet functions and pertubative evolution equations. We show that the dependence on energy and jet size for the average and width of the jet charge can be calculated despite the large experimental uncertainty on fragmentation functions. These calculations can provide a validation tool for data independent of Monte Carlo fragmentation models.

    The nominal SSC and LHC designs should operate conservatively at luminosities up to 10{sup 33} cm{sup {minus}2} s{sup {minus}1}. This luminosity is dictated by the event rates that can be handled by the detectors. However, this limit is event dependent (e.g. it does not take much of a detector to detect the event pp {yields} elephant; all one needs is extremely high luminosity). As such, it is useful to explore the possibility of going beyond the 10{sup 33} cm{sup {minus}2} s{sup {minus}1} level. Such exploration will also improve the accelerator physics understanding of pp collider designs. If the detector limitations are removed, the first accelerator limits occur when the luminosity is at the level of 10{sup 34} cm{sup {minus}2}s{sup {minus}1}. These accelerator limits will first be reviewed. The authors will then continue on to explore even higher luminosity as the ultimate limit of pp colliders. Accelerator technologies needed to achieve this ultimate luminosity as well as the R and D needed to reach it are discussed.

    This study was carried out to characterize three aldehydes of health concern (formaldehyde, acetaldehyde, and acrolein) at a central Beijing site in the summer and early fall of 2008 (from June to October). Aldehydes in polluted atmospheres come from both primary and secondary sources, which limits the control strategies for these reactive compounds. Measurements were made before, during, and after the Beijing Olympics to examine whether the dramatic air pollution control measures implemented during the Olympics had an impact on concentrations of the three aldehydes and their underlying primary and secondary sources. Average concentrations of formaldehyde, acetaldehyde and acrolein were 29.3±15.1 μg/m(3), 27.1±15.7 μg/m(3) and 2.3±1.0 μg/m(3), respectively, for the entire period of measurements, all being at the high end of concentration ranges measured in cities around the world in photochemical smog seasons. Formaldehyde and acrolein increased during the pollution control period compared to the pre-Olympic Games, followed the changing pattern of temperature, and were significantly correlated with ozone and with a secondary formation factor identified by principal component analysis (PCA). In contrast, acetaldehyde had a reduction in mean concentration during the Olympic air pollution control period compared to the pre-Olympic period and was significantly correlated with several pollutants emitted from local emission sources (e.g., NO2, CO, and PM2.5). Acetaldehyde was also more strongly associated with primary emission sources including vegetative burning and oil combustion factors identified through the PCA. All three aldehydes were lower during the post-Olympic sampling period compared to the before and during Olympic periods, likely due to seasonal and regional effects. Our findings point to the complexity of source control strategies for secondary pollutants.

    There is a lack of information on the utilisation of physiotherapy services at the Olympic Games. To better understand the athlete and non-athlete requirements of the physiotherapy services at the Olympic Village Polyclinic during the London 2012 Olympic Games. From 16 July to 14 August 2012, physiotherapy encounters for athletes and non-athletes (National Olympic Committee (NOC) team officials, coaches, team managers, workforce, Olympic family, technical officials and press) were recorded on the ATOS electronic medical records system at the polyclinic in the main Athletes' Village in Stratford. Of the 1778 encounters, 1219 (69%) were administered to athletes and 559 (31%) to non-athletes. The anatomical areas most frequently recorded at the first visits for athletes were knee (15.4%), lumbar spine/lower back (15.2%) and upper leg (12.6%) and that for non-athletes were lumbar spine/lower back (19.8%), knee (15.8%) and neck/cervical spine. Muscle (33.3%) and joint injuries (24.8%) were the most common diagnoses in athletes and non-athletes (24.4% and 30.1%). The five most frequently used treatment modalities were therapeutic soft tissue techniques (23.3%), mobilisation techniques (21.8%), taping (8.9%), cryotherapy (6.9%) and exercise prescription (6.4%). The most common cause of athletes' injuries was overuse (43.6%). This study of the London 2012 Olympic Games workload highlights the physiotherapy needs of athletes as well as non-athletes and identifies the high numbers of pre-existing and overuse injuries in this setting, providing an insight into the reasons why the athletes seek physiotherapy support during the Olympic Games.
