    On January 22, 1988, three large intraplate earthquakes (with MS 6.3, 6.4, and 6.7) occurred within a 12-hour period near Tennant Creek, Australia. These earthquakes, which occurred over a small interval of time and within a small volume of space, present a unique opportunity to study the rupture process of the class of intraplate earthquakes that occur as multiple main shocks. Broadband displacement and velocity records of body waves from teleseismically recorded data are analyzed to determine source mechanisms, depths, and complexity of rupture of each of the three main shocks. Hypocenters of an additional 150 foreshocks and aftershocks constrained by local arrival time data and field observations of surface rupture are used to complement the source characteristics of the main shocks in order to derive as complete a description of the rupture process as possible. The interpretation of the combined data sets suggests that the overall rupture process involved unusually complicated stress release. As locations of the main shock hypocenters progressively moved from west to east, we infer that the first and third main shocks, denoted as MS1 and MS3, produced the southeast-northwest trending scarps observed at the western end (the Kunayungku fault) and at the eastern end (the east end of the Lake Surprise fault), respectively, of the rupture zone. The epicenter of the only immediate foreshock was located in the gap between these two fault scarps. MS1 nucleated near this epicenter and ruptured upward and to the northwest from a depth of 6.5 km. MS3 ruptured predominantly to the SE at a depth of 4.5 km. The second main shock, MS2, is inferred to have produced the deformation of the southwest trending central scarp segment (the western end of the Lake Surprise fault). From the sense of thrusting seen at the surface and from the distribution of aftershock hypocenters, the south dipping nodal planes derived from waveform modeling are identified as the fault planes for earthquakes MS1 and MS3. In contrast, the dip of the central fault scarp is reversed relative to the dips of the western and eastern fault scarps. The rupture process Of MS2 turns out to be commensurately complex and sufficiently explains the geological complexity. MS2 consisted of three subevents. The southeast dipping nodal plane of the first two subevents is coplanar with a southeast dipping plane implied by locations of aftershocks which did not break the surface. Choice of the north dipping plane as the rupture plane of the third subevent, consistent with the surface deformation and coplanar with a second plane delineated by aftershocks, would imply conjugate faulting. The majority of the aftershocks are concentrated near the edges of the fault planes, and there is an absence of activity in the center of the planes. The areas of absent activity may represent the failed asperities of the main shocks in which substantial stress relief occurred. The rupture process of each main shock is characterized by the rapid release of energy followed by a much slower release of moment and by aftershock zones whose dimensions exceed the inferred dimensions of the rupture. These characteristics suggest that substantial slow slip occurred on each of the three fault interfaces that was not accompanied by major energy release. The first main shock nucleated at the deepest part of its aftershock zone and ruptured upward. In contrast, MS2 and MS3 nucleated at depths that were one third to one half of the maximum depth of their aftershock zones. This variation of focal depth and the strong increase of moment and radiated energy with each main shock imply that lateral variations of strength were more important than vertical gradients of shear stress in controlling the progression of rupture.

  4. Remotely triggered earthquakes following moderate main shocks

    Since 1992, remotely triggered earthquakes have been identified following large (M > 7) earthquakes in California as well as in other regions. These events, which occur at much greater distances than classic aftershocks, occur predominantly in active geothermal or volcanic regions, leading to theories that the earthquakes are triggered when passing seismic waves cause disruptions in magmatic or other fluid systems. In this paper, I focus on observations of remotely triggered earthquakes following moderate main shocks in diverse tectonic settings. I summarize evidence that remotely triggered earthquakes occur commonly in mid-continent and collisional zones. This evidence is derived from analysis of both historic earthquake sequences and from instrumentally recorded M5-6 earthquakes in eastern Canada. The latter analysis suggests that, while remotely triggered earthquakes do not occur pervasively following moderate earthquakes in eastern North America, a low level of triggering often does occur at distances beyond conventional aftershock zones. The inferred triggered events occur at the distances at which SmS waves are known to significantly increase ground motions. A similar result was found for 28 recent M5.3-7.1 earthquakes in California. In California, seismicity is found to increase on average to a distance of at least 200 km following moderate main shocks. This supports the conclusion that, even at distances of ???100 km, dynamic stress changes control the occurrence of triggered events. There are two explanations that can account for the occurrence of remotely triggered earthquakes in intraplate settings: (1) they occur at local zones of weakness, or (2) they occur in zones of local stress concentration. ?? 2007 The Geological Society of America.

    We have registered near-field TEC response to the Wenchuan earthquake on 12 May 2008, for the first time. We found that an intensive N-shape shock-acoustic wave with a plane waveform and with half-period of about 200 sec propagated south-eastward with a velocity of 600 m/s for distance about 1000 km. The wavefront of N-shaped disturbance was parallel with the earthquake rupture direction (from SW to NE). The main directional lobe of shock-acoustic wave emitter is directed southeastward, i.e. transversely to the rupture. We suppose that the above properties of TEC response are determined by the geodynamics of the Wenchuan earthquake.

  7. The effects of diaphragm rupture and particle loading in contoured shock tubes for vaccine delivery

    NASA Astrophysics Data System (ADS)

    Truong, N. K.; Hardy, M. P.; Kendall, M. A. F.

    Biological Ballistics, or "Biolistics", is a method by which micro-particle formulations of vaccine can be delivered to human skin or mucosa. A particle acceleration device, the Contoured Shock Tube (CST), has recently been described and characterised experimentally and numerically [2,3,6]. Essentially, the CST comprises a shock tube coupled to a correctly expanded nozzle. The particles are initially retained on a thin diaphragm while the upstream driver section is pressurised with air or helium. Rupture of the diaphragm initiates a classic shock tube flow through the device and consequent nozzle starting process. The design principle of the CST is that the particles be entrained within a quasi-steady, supersonic flow window which is bounded downstream by the nozzle starting process and upstream by the expansion reflected from the driver endwall.

    Forecasting the aftershock probability has been performed by the authorities to mitigate hazards in the disaster area after a main shock. However, despite the fact that most of large aftershocks occur within a day from the main shock, the operational forecasting has been very difficult during this time-period due to incomplete recording of early aftershocks. Here we propose a real-time method for efficiently forecasting the occurrence rates of potential aftershocks using systematically incomplete observations that are available in a few hours after the main shocks. We demonstrate the method's utility by retrospective early forecasting of the aftershock activity of the 2011 Tohoku-Oki Earthquake of M9.0 in Japan. Furthermore, we compare the results by the real-time data with the compiled preliminary data to examine robustness of the present method for the aftershocks of a recent inland earthquake in Japan.

    A simulation of the OECD/NEA ROSA-2 Project Test 5 was made with the thermal-hydraulic code TRACE5. Test 5 performed in the Large Scale Test Facility (LSTF) reproduced a Main Steam Line Break (MSLB) with a Steam Generator Tube Rupture (SGTR) in a Pressurized Water Reactor (PWR). The result of these simultaneous breaks is a depressurization in the secondary and primary system in loop B because both systems are connected through the SGTR. Good approximation was obtained between TRACE5 results and experimental data. TRACE5 reproduces qualitatively the phenomena that occur in this transient: primary pressure falls after the break, stagnation of the pressure after the opening of the relief valve of the intact steam generator, the pressure falls after the two openings of the PORV and the recovery of the liquid level in the pressurizer after each closure of the PORV. Furthermore, a sensitivity analysis has been performed to know the effect of varying the High Pressure Injection (HPI) flow rate in both loops on the system pressures evolution. (authors)

    Autosomal dominant polycystic kidney disease is an important cause of end stage renal failure. Rarely, these patients may present with hemorrhagic shock caused by rupture of the renal cyst. The aim of this study was to report a rare case of a patient who arrived at the emergency department with autosomal dominant polycystic kidney disease presenting with acute abdominal pain and hemorrhagic shock. A 58-year-old male with chronic renal failure was admitted to the emergency department with acute abdominal pain and hemorrhagic shock. The patient was admitted to the Department of Surgery with diagnosis of acute abdomen and perirenal hematoma. Although the patient was on conservative treatment, his symptoms did not improve and the patient was operated emergently. During exploration, there was bleeding from the right polycystic kidney, which was 30×20 cm in dimension. The patient underwent nephrectomy and drainage of the hematoma, and was discharged on the fifth postoperative day without any problems. Bleeding due to rupture of a cyst in autosomal dominant polycystic kidney disease occurs rarely but it may be life threatening. Although conservative methods are often preferable in treatment, surgery can be life saving for patients in whom the clinical situation does not improve. PMID:25931844

    The 2014 seismic sequence in Northern Chile culminated with the Mw8.1 Pisagua earthquake (2014/04/01), rapidly followed by a large aftershock close to Iquique (Mw=7.6, 2014/04/03). A detailed analysis of these two earthquakes is required to better relate these major events with their preparatory phase, and in particular with the intense activity of the area between March 16th and April 1st. This area has been densely instrumented by several international and Chilean projects, including strong motion and broadband sensors as well as high-rate GPS stations. In this study, we make an extensive use of the seismo-geodetic data collected by the IPOC/CSN (http://www.ipoc-network.org/) and ONEMI networks. In a first step, we model several of the foreshocks with magnitudes in the range [5.5 6.5] in order to determine a seismic velocity model able to reproduce the observations up to 0.1Hz. This velocity model is then used to analyze the rupture process of the two main shocks. Besides the use of the local displacement waveforms (coming from strong motion sensors and high-rate GPS), the inversion procedure also includes the static GPS displacements and the teleseismic P and SH waves. The source models are finally validated with other geophysical information not included in the inversion, such as InSAR or surface waves analysis through an empirical Green function approach. These data consistently show that most of the coseismic slip of the 1st April main shock is located in a 50km long zone (along strike), close and South from the hypocenter. In the time domain, this large slip patch has been activated 15-20s after origin time and lasted about 30s. Before this activation, seismic moment release was low and rupture remained in the hypocentral region. Differences and relations between the two shocks, as well as their interpretation in the 2014 seismic sequence, will be discussed.

    Diaphragmatic rupture (DR) after thoracoabdominal trauma has a reported rate of 0.8% to 5% and up to 30% of diaphragmatic hernias are accompanied with delayed diagnosis. The DR occurs after high-energy blunt or penetrating (stab or gunshot wounds) trauma. The purpose of this article is to analyze the DR, its clinical presentation, complications and possible causes of the delay in diagnosis, whilst recording a rare interesting case. A 44-year old moribund male with a fifteen years history of paraplegia, came to the emergency department with a clinical presentation of extremely severe respiratory distress. Chest X-ray showed the colon present in the left hemithorax. The onset of symptoms was 48 hours before, resulting in hemodynamic instability and severe sepsis condition. Emergency left thoracotomy and laparotomy were carried out. A rupture of the left hemidiaphragm was found as well as intrathoracic presence of colon, incarcerated and perforated, feces and omentum, also incarcerated and necrotic. There were dense adhesions between the ectopic viscera and the thoracic structures. The necrotic parts of the colon and the omentum were mobilized, and then resected. The viable parts of the colon were laboriously reintroduced into the intraperitoneal cavity. We conclude that early diagnosis is crucial to the morbidity and mortality after DR. The course and the kinetic energy of bullets determine the extent of the wound and the size of the DR. The diagnosis of rupture of the diaphragm after penetrating trauma is sometimes difficult and delay can lead to life threatening complications. PMID:24255791

    On 28 September 2004 there was an earthquake of magnitude 6.0 at Parkfield, California. Here we show that the size distribution of the micro-earthquakes recorded in the decades before the main shock occurred allowed an accurate forecast of its eventual rupture area. Applying this approach to other well monitored faults should improve earthquake hazard assessment in future. PMID:15858563

    The October 17, 1989, Loma Prieta, Calif., earthquake (0004:15.2 G.m.t. October 18; lat 37.036? N., long 121.883? W.; 19-km depth) had a local magnitude (ML) of about 6.7, a surface-wave magnitude (MS) of 7.1, a seismic moment of 2.2x1019 N-m to 3.5x1019 N-m, a source duration of 6 to 15 s, and an average stress drop of at least 50 bars. Slip occurred on a dipping fault surface about 35 km long and was largely confined to a depth of about 7 to 20 km. The slip vector had a large vertical component, and slip was distributed in two main regions situated northwest and southeast of the hypocenter. This slip distribution caused about half of the earthquake's energy to be focused toward the urbanized San Francisco Bay region, while the other half was focused toward the southeast. Had the rupture initiated at the southeast end of the aftershock zone, shaking in the bay region would have been both longer and stronger. These source parameters suggest that the earthquake was not a typical shallow San Andreas-type event but a deeper event on a different fault with a recurrence interval of many hundreds of years. Therefore, the potential for a damaging shallow event on the San Andreas fault in the Santa Cruz Mountains may still exist.

    The August 17, 1999 Izmit (Turkey) earthquake (Mw=7.4) will be remembered as one of the largest earthquakes of recent times that affected a large urban environment (U.S. Geological Survey, 1999). This significant event was followed by many significant aftershocks and another main event (Mw=7.2) that occurred on November 12, 1999 near Duzce (Turkey). The shaking that caused the widespread damage and destruction was recorded by a handful of accelerographs (~30) in the earthquake area operated by different networks. The characteristics of these records show that the recorded peak accelerations, shown in Figure 1, even those from near field stations, are smaller than expected (Çelebi, 1999, 2000). Following this main event, several organizations from Turkey, Japan, France and the USA deployed temporary accelerographs and other aftershock recording hardware. Thus, the number of recording stations in the earthquake affected area was quadrupled (~130). As a result, as seen in Figure 2, smaller magnitude aftershocks yielded larger peak accelerations, indicating that because of the sparse networks, recording of larger motions during the main shock of August 17, 1999 were possibly missed.

    A man in his 80s underwent urgent endovascular aortic repair (EVAR) for a ruptured abdominal aortic aneurysm (RAAA). Surgery was completed without apparent complications, and the patient was returned to the Cardiac Care Unit. Two hours later, he again developed shock, and contrast-enhanced Computed Tomography showed extravasation from a type II endoleak (T2EL) involving the IMA. Transcatheter arterial embolization (TAE) was immediately performed, and the patient’s vital signs stabilized soon after embolization. Abdominal compartment syndrome was suspected during the procedure, so a retroperitoneal hematoma evacuation was performed. The patient’s postoperative course was satisfactory, and he transferred to another hospital. EVAR for RAAA would be useful, but it is necessary to be considered that T2EL can cause the aggravation of unstable circulation.

    A recent study by Llenos and McGuire (2007) uses second moments to create rupture models for 15 great subduction zone earthquakes and compares the centroid and rupture extent results relative to trench parallel gravity anomalies (TPGA). They find that for 75 percent of the events studied, TPGA increases between earthquake centroid and the edges of rupture, indicating structural control on rupture arrest. As an independent test of this relationship, we are using a modified Joint Hypocenter Determination code to relocate aftershocks of the events studied by Llenos and McGuire (2007). Available arrival time data have proven adequate to robustly relocate 8 of the 15 aftershock sequences. Our preliminary results show good agreement between the aftershock distributions and the Llenos and McGuire (2007) rupture extent and directivity results for 5 events. We do not observe a clear-cut relationship between TPGA features and the aftershock zone, however. We will explore the use of waveform cross-correlation to provide additional and more accurate arrival time picks for first arrivals and depth phases in order to extend our analysis to the remaining sequences.

    We analyze the properties of Large Scale Shocks in a cosmological volume of size 103Mpc/h simulated with the public 1.0.1 release of the ENZO code. Different methods to identify and characterize shocks in post processing are discussed together with their uncertainties. Re-ionization affects the properties of shocks in simulations, and we propose a fitting procedure to model accurately the effect of re-ionization in non--radiative simulations, with a post--processing procedure. We investigate the properties of shocks by means of a procedure which uses jumps in the velocity variables across the cells in the simulations and this allows us to have a viable description of shocks also in relatively under-dense cosmic regions. We derive the distributions of the number of shocks and of the energy dissipated at these shocks as a function of their Mach number, and discuss the evolution of these distributions with cosmological time and across different cosmic environments (clusters, outskirts, filaments, voids). In line with some previous numerical studies (e.g. Ryu et al.2003, Pfrommer et al.2006) relatively weak shocks are found to dominate the process of energy dissipation in the simulated cosmic volume, although we find a larger ratio between weak and strong shocks with respect to previous studies. We estimate the rate of injection of CR at Large Scale Shocks by adopting injection efficiencies taken from previous numerical calculations. The flux dissipated in the form of CR within the whole simulated volume at the present epoch is about 20 per cent of the thermal energy dissipated at shocks; this fraction is smaller within galaxy clusters.

    Seismic risk assessment involves the development of fragility functions to express the relationship between ground motion intensity and damage potential. In evaluating the risk associated with the building inventory in a region, it is essential to capture 'actual' characteristics of the buildings and group them so that 'generic building types' can be generated for further analysis of their damage potential. Variations in building characteristics across regions/countries largely influence the resulting fragility functions, such that building models are unsuitable to be adopted for risk assessment in any other region where a different set of building is present. In this paper, for a given building type (represented in terms of height and structural system), typical New Zealand and US building models are considered to illustrate the differences in structural model parameters and their effects on resulting fragility functions for a set of main-shocks and aftershocks. From this study, the general conclusion is that the methodology and assumptions used to derive basic capacity curve parameters have a considerable influence on fragility curves.

    Tracheobronchial injury (TBI) may lead to catastrophe if remains undetected or managed improperly. The incidence of TBI is less in children as compared with adults due to their pliable chest wall. Its clinical manifestations include persistent pneumothorax, cervical subcutaneous emphysema, pneumomediastinum, cyanosis, and respiratory insufficiency. The recommended airway management is to intubate the healthy bronchus with a single-lumen or double-lumen endotracheal tube (ET) and bypassing the injured side. We report successful anesthetic management of traumatic rupture of the left main bronchus in a child by using a single-lumen cuffed-ET. Many factors affect the outcome of such injuries and include the extent of the lesion, the resulting pulmonary status, the adequacy of surgical reconstruction. More severe injury may require lobectomy or pneumonectomy. Early diagnosis and proper management result in good functional outcome. PMID:25281627

    The Chilean subduction zone is among the seismically most active plate boundaries in the world and its coastal ranges suffer from a magnitude 8 or larger megathrust earthquake every 10-20 years. The Constitución-Concepción or Maule segment in central Chile between ~35.5°S and 37°S was considered to be a mature seismic gap, rupturing last in 1835 and being seismically quiet without any magnitude 4.5 or larger earthquakes reported in global catalogues. It is located to the north of the nucleation area of the 1960 magnitude 9.5 Valdivia earthquake and to the south of the 1928 magnitude 8 Talca earthquake. On 27 February 2010 this segment ruptured in a Mw=8.8 earthquake, nucleating near 36°S and affecting a 500-600 km long segment of the margin between 34°S and 38.5°S. Aftershocks occurred along a roughly 600 km long portion of the central Chilean margin, most of them offshore. Therefore, a network of 30 ocean-bottom-seismometers was deployed in the northern portion of the rupture area for a three month period, recording local offshore aftershocks between 20 September 2010 and 25 December 2010. In addition, data of a network consisting of 33 landstations of the GeoForschungsZentrum Potsdam were included into the network, providing an ideal coverage of both the rupture plane and areas affected by post-seismic slip as deduced from geodetic data. Aftershock locations are based on automatically detected P wave onsets and a 2.5D velocity model of the combined on- and offshore network. Aftershock seismicity analysis in the northern part of the survey area reveals a well resolved seismically active splay fault in the accretionary prism of the Chilean forearc. Our findings imply that in the northernmost part of the rupture zone, co-seismic slip most likely propagated along the splay fault and not the subduction thrust fault. In addition, the updip limit of aftershocks along the plate interface can be verified to about 40 km landwards from the deformation front. Prior to the Great Maule earthquake the Collaborative Research Center SFB 574 'Volatiles and Fluids in Subduction Zones' shot several wide-angle profiles and operated a network, also consisting of OBS and land stations for six months in 2008. Both projects provide a great opportunity to study the evolution of a subduction zone within the seismic cycle of a great earthquake. The most profound features are (i) a sharp reduction in intraslab seismic activity after the Maule earthquake and (ii) a sharp increase in seismic activity at the slab interface above 50 km depth, where large parts of the rupture zone were largely aseismic prior to the Maule earthquake. Further, the aftershock seismicity shows a broader depth distribution above 50 km depth.

    Splenic rupture is a common injury associated with blunt abdominal trauma. In contrast, delayed splenic rupture is less frequent and comprises about 8--28% of cases of splenic rupture. The symptom free period can last for days or weeks. The mechanism is explained as follows. A rupture of the parenchyma occurs but the spleen capsula remains intact. A hematoma forms below the capsule and causes a strong overdistension of the capsule so that a bursting and release of blood into the abdominal cavity results. The mortality rate with splenic ruptures in 6--55% and with delayed splenic ruptures 14.6%. Our experiences are reviewed. After commencement of the hemorrhage therapy must consist of treatment for shock and immediate laparotomy and splenectomy. PMID:44648

    Whether the rupture process of small earthquakes differs from those of large earthquakes has been a long- standing question in seismology. Recent proposals as to whether and how the physics of rupture may change with earthquake size have sparked interest in the energy budget, which depends strongly on the rupture velocity (Vr). Small earthquake rupture velocities have proved difficult to determine due to the strong attenuation of high-frequency waves. We analyze P and S waves of small earthquakes to detect rupture directivity and constrain Vr. We apply the projected Landweber deconvolution (PLD) method to a data set of 30 earthquakes 3.6main shocks and obtain the relative source time functions (RSTF). The EGF approach removes the effects of complex structure between the earthquakes and the stations. Variation in RSTFs with azimuth yields estimates of Vr for 6 earthquakes from 0.4 to 0.9?. Our results are broadly consistent with those of Yamada and Mori (JGR, 2005) and McGuire (BSSA, 2004). We now explore the implications of the range in Vr for static stress drop (??), and the ratio of radiated energy to seismic moment, which are interrelated. Kanamori and Rivera (BSSA, 2004) discuss how Vr and ?? must change with earthquake moment, if the ratio of energy to moment ? increases with moment, as has been suggested by various studies. There is currently no consensus that such a change in this ratio truly occurs. The increase in the energy-to- moment ratio is controlled by the relation between moment and corner frequency, which has moment inversely proportional to corner frequency raised to the power (3 + ?). Data compiled in Kanamori and Rivera suggests ? of 0.5. Then Vr of 0.4 to 0.9? for M3 events require that ?? of M3 events range from 1 to 0.1 respectively, of that of M7 events. More constraints on rupture velocities of small earthquakes will help to resolve possible changes in the energy budget, and thus earthquake physics, with earthquake size.

    We propose a new technique to determine the rupture velocity of large strike slip earthquakes. By means of simple numerical ground motion simulations, we show that when the rupture penetrates a shallow layer of sediment or fractured rock, shock waves propagate along the surface fault trace in the forward rupture direction. Such shock waves, which are insensitive to the complexity of slip over the fault plane, propagate at a phase velocity equal to the rupture speed. We show that those shock waves can be easily isolated in the frequency domain, and that phase velocity can then be simply obtained from shear strain.

    Renal angiomyolipoma is a benign tumor of the kidney, originating from perivascular epithelioid cells. Normally asymptomatic, symptoms that can occur are flank pain due to strong growth or spontaneous rupture with retroperitoneal hemorrhage and hypovolemic shock. The risk of rupture is higher during pregnancy and also growth can be enhanced, probably hormone mediated. We report a case of a ruptured renal angiomyolipoma during childbirth in a woman who presented with hypovolemic shock as a result of retroperitoneal hemorrhage. Emergency endovascular treatment was successful with sparing most of the affected kidney as demonstrated by angiography imaging and follow-up computed tomographic scan. PMID:25669735

    Annually, over 500,000 women die from complications of pregnancy and childbirth; the majority die from hemorrhage and shock. Obstetrical hemorrhage of all etiologies, such as uterine atony, ruptured uterus, and ruptured ectopic, can cause massive blood loss resulting in severe shock. Unless women can access fluid replacement, blood transfusions, and, often, surgery, the shock leads to organ failure and death.

    This study incorporates the rupture geometry of big earthquakes in the formulation of the Epidemic-Type Aftershock Sequence (ETAS) model, which is a point process model widely applied in the study of spatiotemporal seismicity, rather than regarding every earthquake occurring at a point in space and time. We apply the new model to the catalog from Sichuan province, China, between 1990 and 2013, during which the Wenchuan Mw7.9 earthquake occurred in May 2008. Our results show that the modified model has better performance in both data fitting and aftershock simulation, confirming that the elliptic aftershock zone is caused by the superposition of the isotropic triggering effect from each patch of the rupture zone. Moreover, using the technique of stochastic reconstruction, we inverted the fault geometry and verified that direct aftershocks of the main shock more likely occur in the transitive parts from high-slip parts to low/median slip parts of the main shock fault area.

We test this model with 450 small earthquakes (2 < M < 5) from Parkfield, California, to look for evidence of consistent <span class="hlt">rupture</span> directivity along the San Andreas Fault. We analyze azimuthal variations in earthquake source spectra after applying an iterative correction for wave propagation effects. Our approach avoids directly modeling source spectra because these models generally assume symmetric <span class="hlt">rupture</span>; instead, we look for azimuthal variations in the amplitudes of the source spectra over specified frequency bands. Our overall results show similar proportions of events exhibiting characteristics of <span class="hlt">rupture</span> directivity toward either the southeast or northwest.

Applications include remote fire suppression, single-use system-pressurization systems, spacecraft propellant systems, and in situ instruments. Current pyrotechnic- activated <span class="hlt">rupture</span> disk hermetic valves were designed for physically larger systems and are heavy and integrate poorly with portable equipment, aircraft, and small spacecraft and instrument systems. Additionally, current pyrotechnically activated systems impart high g-force <span class="hlt">shock</span> loads to surrounding components and structures, which increase the risk of damage and can require additional mitigation. The disclosed mechanism addresses the need for producing a hermetically sealed micro-isolation valve for low and high pressure for commercial, aerospace, and spacecraft applications. High-precision electrical discharge machining (EDM) parts allow for the machining of mated parts with gaps less than a thousandth of an inch. These high-precision parts are used to support against pressure and extrusion, a thin hermetically welded diaphragm. This diaphragm <span class="hlt">ruptures</span> from a pressure differential when the support is removed and/or when the plunger is forced against the diaphragm. With the addition of conventional seals to the plunger and a two-way actuator, a derivative of this design would allow nonhermetic use as an on/off or metering valve after the initial <span class="hlt">rupturing</span> of the hermetic sealing disk. In addition, in a single-use hermetically sealed isolation valve, the valve can be activated without the use of potential leak-inducing valve body penetrations. One implementation of this technology is a high-pressure, high-flow-rate <span class="hlt">rupture</span> valve that is self-<span class="hlt">rupturing</span>, which is advantageous for high-pressure applications such as gas isolation valves. Once initiated, this technology is self-energizing and requires low force compared to current pyrotechnic-based burst disk hermetic valves. This is a novel design for producing a single-use, self-<span class="hlt">rupturing</span>, hermetically sealed valve for isolation of pressurized gas and/or liquids. This design can also be applied for single-use disposable valves for chemical instruments. A welded foil diaphragm is fully supported by two mated surfaces that are machined to micron accuracies using EDM. To open the valve, one of the surfaces is moved relative to the other to (a) remove the support creating an unsupported diaphragm that <span class="hlt">ruptures</span> due to over pressure, and/or (b) produce tension in the diaphragm and <span class="hlt">rupture</span> it.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=NASAADS&redirectUrl=http://adsabs.harvard.edu/abs/2002AGUFMNG21B0939D"><span id="translatedtitle">Fault Branching and <span class="hlt">Rupture</span> Directivity</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Dmowska, R.; Rice, J. R.; Kame, N.</p> <p>2002-12-01</p> <p>Can the <span class="hlt">rupture</span> directivity of past earthquakes be inferred from fault geometry? Nakata et al. [J. Geogr., 1998] propose to relate the observed surface branching of fault systems with directivity. Their work assumes that all branches are through acute angles in the direction of <span class="hlt">rupture</span> propagation. However, in some observed cases <span class="hlt">rupture</span> paths seem to branch through highly obtuse angles, as if to propagate ``backwards". Field examples of that are as follows: (1) Landers 1992. When crossing from the Johnson Valley to the Homestead Valley (HV) fault via the Kickapoo (Kp) fault, the <span class="hlt">rupture</span> from Kp progressed not just forward onto the northern stretch of the HV fault, but also backwards, i.e., SSE along the HV [Sowers et al., 1994, Spotila and Sieh, 1995, Zachariasen and Sieh, 1995, Rockwell et al., 2000]. Measurements of surface slip along that backward branch, a prominent feature of 4 km length, show right-lateral slip, decreasing towards the SSE. (2) At a similar crossing from the HV to the Emerson (Em) fault, the <span class="hlt">rupture</span> progressed backwards along different SSE splays of the Em fault [Zachariasen and Sieh, 1995]. (3). In crossing from the Em to Camp Rock (CR) fault, again, <span class="hlt">rupture</span> went SSE on the CR fault. (4). Hector Mine 1999. The <span class="hlt">rupture</span> originated on a buried fault without surface trace [Li et al., 2002; Hauksson et al., 2002] and progressed bilaterally south and north. In the south it met the Lavic Lake (LL) fault and progressed south on it, but also progressed backward, i.e. NNW, along the northern stretch of the LL fault. The angle between the buried fault and the northern LL fault is around -160o, and that NNW stretch extends around 15 km. The field examples with highly obtuse branch angles suggest that there may be no simple correlation between fault geometry and <span class="hlt">rupture</span> directivity. We propose that an important distinction is whether those obtuse branches actually involved a <span class="hlt">rupture</span> path which directly turned through the obtuse angle (while continuing also on the <span class="hlt">main</span> fault), or rather involved arrest by a barrier on the original fault and jumping [Harris and Day, JGR, 1993] to a neighboring fault on which <span class="hlt">rupture</span> propagated bilaterally to form what appears as a backward-branched structure. Our studies [Poliakov et al., JGR in press, 2002; Kame et al, EOS, 2002] of stress fields around a dynamically moving mode II crack tip show a clear tendency to branch from the straight path at high <span class="hlt">rupture</span> speeds, but the stress fields never allow the <span class="hlt">rupture</span> path to directly turn through highly obtuse angles, and hence that mechanism is unlikely. In contrast, study of fault maps in the vicinity of the Kp to HV fault transition [Sowers et al., 1994], discussed as case (1) above, strongly suggest that the large-angle branching occurred as a jump, which we propose as the likely general mechanism. Implications for the Nakata et al. [1998] aim of inferring <span class="hlt">rupture</span> directivity from branch geometry is that this will be possible only when rather detailed characterization (by surface geology, seismic relocation, trapped waves) of fault connectivity can be carried out in the vicinity of the branching junction, to ascertain whether direct turning of the <span class="hlt">rupture</span> path through an angle, or jumping and then propagating bilaterally, were involved in prior events. They have opposite implications for how we would associate past directivity with a (nominally) branched fault geometry.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=NASAADS&redirectUrl=http://adsabs.harvard.edu/abs/1993Geo....21..387L"><span id="translatedtitle">Three-dimensional tomography of the 1992 southern California earthquake sequence: Constraints on dynamic earthquake <span class="hlt">rupture</span>?</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Lees, Jonathan M.; Nicholson, Craig</p> <p>1993-05-01</p> <p>Tomographic inversion of P</em>-wave arrival times from aftershocks of 1992 southern California earthquakes is used to produce three dimensional images of subsurface velocity.

This experimental maximum <span class="hlt">rupture</span> speed is by far lower than those predicted by theories and inferred from inversions of seismograms, and some seismic inversions (e.g., the 1979 Imperial Valley, 1992 Landers, 1999 Izmit, 2001 the central Kunlunshan and 2002 Denali earthquakes) even suggest the existence of supershear <span class="hlt">rupture</span> speeds (i.e., <span class="hlt">rupture</span> propagating faster than the relevant shear wave). Recently, Uenishi et al. ( SSJ Fall Meeting, 2004, 2005; AGU Fall Meeting, 2006) experimentally investigated dynamic fracture in monolithic hyperelastic materials under static mode-§ loading conditions with relatively high crack-parallel stresses. Using a high-speed digital video camera system, they showed that cracks may propagate supersonically even in homogeneous materials. However, the exact mechanism for <span class="hlt">rupture</span> nucleation and the transition of a nucleated <span class="hlt">rupture</span> from sub-Rayleigh to super-shear <span class="hlt">rupture</span> speed has not been identified yet. In this contribution, we further develop our experimental system and investigate dynamic fracture in extremely heterogeneous media, consisting of thin fluid and solid films: Inside a wire frame (50mm high, 50mm wide), a flat soap film contacts a flat thin solid plastic film (20mm high, 20mm wide), under static tensile loading conditions. The <span class="hlt">rupture</span> (crack), initiated at a point, propagates subsonically in the linear elastic fluid film (see e.g., Uenishi et al., SSJ Fall Meeting, 2006, for the dynamic <span class="hlt">rupture</span> in monolithic fluid films). When the circular <span class="hlt">rupture</span> front reaches the interface, the <span class="hlt">rupture</span> advances along the interface and then it is "diffracted" at the two corners of the interface. We record the <span class="hlt">rupture</span> propagation process utilizing our high-speed digital video camera at a frame rate of 20 ?s (20×10-6s). The observed results show that interface <span class="hlt">rupture</span> propagation may accelerate (or even decelerate) and the dynamic <span class="hlt">rupture</span> behavior is very sensitive to the geometry of the interface between the two films: (1) When the subsonic <span class="hlt">rupture</span> front reaches the first rectangular corner, it accelerates around the corner and then advances supersonically along the interface; and (2) when the supersonic interface <span class="hlt">rupture</span> front approaches the second corner (obtuse with respect to the <span class="hlt">rupture</span> front in fluid), it bifurcates for a short period (400 ?s): the first branch unexpectedly expands rather straight into the bulk and the second one propagates along the interface at a lower speed; At a later stage, again unexpectedly, the first branched crack decelerates significantly in the bulk and the two cracks eventually merge into a single crack. The overall behavior is - in some sense - similar to that of the oblique <span class="hlt">shock</span> and Prandtl- Meyer expansion waves in fluid mechanics, and it might give new insights not only into the question of high <span class="hlt">rupture</span> speeds of natural earthquakes but also into the generation mechanism of tsunamis. u.ac.jp/~uenishi/</p> </li> </ol> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_1");'>1</a></li> <li class="active"><span>2</span></li> <li><a href="#" onclick='return showDiv("page_3");'>3</a></li> <li><a href="#" onclick='return showDiv("page_4");'>4</a></li> <li><a href="#" onclick='return showDiv("page_5");'>5</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div><!-- col-sm-12 --> </div><!-- row --> </div><!-- page_2 --> <div id="page_3" class="hiddenDiv"> <div class="row"> <div class="col-sm-12"> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_1");'>1</a></li> <li><a href="#" onclick='return showDiv("page_2");'>2</a></li> <li class="active"><span>3</span></li> <li><a href="#" onclick='return showDiv("page_4");'>4</a></li> <li><a href="#" onclick='return showDiv("page_5");'>5</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div> </div> <div class="row"> <div class="col-sm-12"> <ol class="result-class" start="41"> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=NASAADS&redirectUrl=http://adsabs.harvard.edu/abs/2011GeoRL..3810310D"><span id="translatedtitle">Fault zone properties affecting the <span class="hlt">rupture</span> evolution of the 2009 (Mw 6.1) L'Aquila earthquake (central Italy): Insights from seismic tomography</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Di Stefano, R.; Chiarabba, C.; Chiaraluce, L.; Cocco, M.; De Gori, P.; Piccinini, D.; Valoroso, L.</p> <p>2011-05-01</p> <p>We have inverted P- and S-wave travel times from seismograms recorded by a dense local network to infer the velocity structure in the crustal volume where the April 6th 2009 <span class="hlt">main</span> <span class="hlt">shock</span> nucleated.

The comparison between the spatial variations of VP and Poisson ratio within the <span class="hlt">main</span> <span class="hlt">shock</span> nucleation volume inferred in this study with the <span class="hlt">rupture</span> history imaged by inverting geophysical data allows us to interpret the delayed along-strike propagation in terms of heterogeneity of lithology and material properties.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=USGSPUBS&redirectUrl=http://pubs.er.usgs.gov/publication/70016902"><span id="translatedtitle">High-frequency spectral falloff of earthquakes, fractal dimension of complex <span class="hlt">rupture</span>, b value, and the scaling of strength on faults</span></a></p> <p><a target="_blank" href="http://pubs.er.usgs.gov/pubs/index.jsp?view=adv">USGS Publications Warehouse</a></p> <p>Frankel, A.</p> <p>1991-01-01</p> <p>The high-frequency falloff ??-y of earthquake displacement spectra and the b value of aftershock sequences are attributed to the character of spatially varying strength along fault zones. I assume that the high frequency energy of a <span class="hlt">main</span> <span class="hlt">shock</span> is produced by a self-similar distribution of subevents, where the number of subevents with radii greater than R is proportional to R-D, D being the fractal dimension. In the model, an earthquake is composed of a hierarchical set of smaller earthquakes. The static stress drop is parameterized to be proportional to R??, and strength is assumed to be proportional to static stress drop. I find that a distribution of subevents with D = 2 and stress drop independent of seismic moment (?? = 0) produces a <span class="hlt">main</span> <span class="hlt">shock</span> with an ??-2 falloff, if the subevent areas fill the <span class="hlt">rupture</span> area of the <span class="hlt">main</span> <span class="hlt">shock</span>. By equating subevents to "islands' of high stress of a random, self-similar stress field on a fault, I relate D to the scaling of strength on a fault, such that D = 2 - ??. Thus D = 2 corresponds to constant stress drop scaling (?? = 0) and scale-invariant fault strength. A self-similar model of aftershock <span class="hlt">rupture</span> zones on a fault is used to determine the relationship between the b value, the size distribution of aftershock <span class="hlt">rupture</span> zones, and the scaling of strength on a fault. -from Author</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=SCIGOV-MAS&redirectUrl=http://academic.research.microsoft.com/Publication/33218799"><span id="translatedtitle"><span class="hlt">Ruptured</span> intracranial dermoid cysts</span></a></p> <p><a target="_blank" href="http://academic.research.microsoft.com/">Microsoft Academic Search </a></p> <p>K.

Starting the day after the <span class="hlt">main</span> <span class="hlt">shock</span>, we operated, sometime simultaneously, short (~75 m range) and medium (~400m range) range laser scanners on a truck or backpack. We scanned most of the length of the principal and secondary surface <span class="hlt">ruptures</span> at speeds less than 10 km/hr. Scanning occurred primarily in either suburban subdivisions or cultivated vineyards of varying varietals with differing leaf patterns and stages of maturity. Spot-spacing is dense enough (100s of points/m^2) to permit creation of 10-25cm digital elevation models of much of the surface <span class="hlt">rupture</span>. Scanned features of the right-lateral <span class="hlt">rupture</span> include classic mole tracks through a variety of soil types, en echelon cracks, offset vine rows, and myriad types of pavement-related deformation. We estimate coseismic surface displacements ranging from 5 to 45 cm by examining offset cultural features and vine rows and by comparing the MLS data with preexisting airborne laser scans from 2003 using point-cloud and solid-modeling methodologies. Additionally, we conducted repeat MLS scans to measure the magnitude and spatial variation of fault afterslip, exceeding 20 cm in some places, particularly in the southern portion of the <span class="hlt">rupture</span> zone. We anticipate these data sets, in conjunction with independently collected ground-based alinement arrays and space-based geodetic data will contribute significant insight into topics of current debate including assessing the most appropriate material models for shallow fault zones and how shallow and deeper fault slip relate to one another.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=EPRINT&redirectUrl=http://www.rosakis.caltech.edu/downloads/pubs/2010/175%20The%20Effects%20part%20II.pdf"><span id="translatedtitle">The effect of asymmetric damage on dynamic shear <span class="hlt">rupture</span> propagation II: With mismatch in bulk elasticity</span></a></p> <p><a target="_blank" href="http://www.osti.gov/eprints/">E-print Network</a></p> <p>Rosakis, Ares J.</p> <p></p> <p><span class="hlt">ruptures</span> in elastic bimaterials propagate either at sub-shear speed or at the P-wave speed of the softer-fault damage.

Despite the magnitude of this injury, reliable risk assessment has not been clearly defined, and prevention strategies have been limited. The purpose of this review is to identify potential intrinsic and extrinsic risk factors for AT <span class="hlt">rupture</span> in aerial and ground athletes stated in the current literature. Evidence Acquisition: A MEDLINE search was conducted on AT <span class="hlt">rupture</span>, or “injury” and “risk factors” and “athletes” from 1980 to 2011. Emphasis was placed on epidemiology, etiology, and review articles focusing on the risk for lower extremity injury in runners and gymnasts. Thirty articles were reviewed, and 22 were included in this assessment. Results: Aerial and ground athletes share many intrinsic risk factors for AT <span class="hlt">rupture</span>, including overuse and degeneration of the tendon as well as anatomical variations that mechanically put an athlete at risk. Older athletes, athletes atypical in size for their sport, high tensile loads, leg dominance, and fatigue also may increase risk. Aerial athletes tend to have more extrinsic factors that play a role in this injury due to the varying landing surfaces from heights and technical maneuvers performed at various skill levels. Conclusion: Risk assessment for AT <span class="hlt">rupture</span> in aerial and ground athletes is multivariable and difficult in terms of developing prevention strategies. Quantitative measures of individual risk factors may help identify major contributors to injury.

In order to understand the earthquake cycles including stages of strain energy accumulation and of its release, it is essential to answer the following questions; where the limit of <span class="hlt">rupture</span> propagation is located and how the <span class="hlt">rupture</span> stopped. In March, 2011, the M9 Tohoku earthquake occurred off the northeastern part of Japan. A number of studies about the location of its source region have been conducted. Results of these studies share a common feature: the source region extends ~200 km from the trench axis in the down-dip direction, and ~400 km in the along-strike direction. At the southern limit of the source region, the largest aftershock of a size of M7.8 occurred 30 minutes after the <span class="hlt">main</span> <span class="hlt">shock</span>. We had noticed seismicity boundaries around the northern limit of the source area. We conducted a series of marine active-source seismic surveys across the seismicity boundaries using ocean bottom seismometers in 1996, 2001 and 2002. The amplitude of reflections from the plate interface show good anti-correlations with the seismicity: large amplitude reflections are observed in the low-seismicity regions. We discussed that such large amplitude can be ascribed to the existence of a fluid-rich low-Vp layer along the plate interface so that the inter-plate mechanical coupling is weak. Around the southern boundary of the source region, M7-class earthquakes repeatedly occurred at a constant interval of 20 years. We conducted a marine active-source seismic survey in 2004, and a passive seismic observation in 2005. We identified a subducted seamount at a 10 km depth and a trace of seamount subduction along the plate interface. The seismicity in the region corresponds to such structural heterogeneity. A couple of studies show that the <span class="hlt">rupture</span> propagation during the largest aftershock of the Tohoku earthquake was limited by the existence of the subducting seamount. We identified, around both northern and southern limits of the source region of the 2011 Tohoku earthquake, some structural heterogeneities along the plate interface that correlate well with the seismicity. Such structural heterogeneities may control the limit of <span class="hlt">rupture</span> propagation. We continue our investigations by conducting seismic observations and surveys around the <span class="hlt">rupture</span> boundaries in order to better define those boundaries and to understand mechanisms to stop the <span class="hlt">rupture</span> propagation.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=PUBMED&redirectUrl=http://www.ncbi.nlm.nih.gov/pubmed/21426597"><span id="translatedtitle">[Symphysis <span class="hlt">rupture</span> during partus].</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Nouta, Klaas-Auke; Van Rhee, Marina; Van Langelaan, Evert J</p> <p>2011-01-01</p> <p>A few hours after the birth of her first child a 36-year-old woman developed anterior pelvic pain.

In the long-term scale, the largest events define seismic cycles or super cycles. Seismic events are separated by slow <span class="hlt">ruptures</span> that concentrate stresses at the strongest, locked fault patches, or asperities. A complex interplay between seismic and aseismic slips has been revealed both by computer simulations (e.g., Senatorski, 2002) and observations (e.g., Kato et al., 2012). The objective of the present work is to relate different distributions of plate coupling strengths to earthquake sequence characteristics and earthquake statistics, focusing on the role played by slow slips during seismic cycles. It is shown that the strength distributions are responsible for both the long-term shear stress along the plate interface and subsequent earthquake patterns.

This poster will review the dimensionless parameters that determine structure in these <span class="hlt">shocks</span> and will discuss recent experiments to measure such structure for strongly radiative <span class="hlt">shocks</span> that are optically thin upstream and optically thick downstream. The <span class="hlt">shock</span> transition itself heats <span class="hlt">mainly</span> the ions. Immediately downstream of the <span class="hlt">shock</span>, the ions heat the electrons and the electrons radiate, producing an optically thin cooling layer, followed by the downstream layer of warm, <span class="hlt">shocked</span> material. The axial structure of these systems is of interest, because the transition from precursor through the cooling layer to the final state is complex and difficult to calculate. Their lateral structure is also of interest, as they seem likely to be subject to some variation on the Vishniac instability of thin layers. In our experiments to produce such <span class="hlt">shocks</span>, laser ablation launches a Be plasma into a tube of Xe or Ar gas, at a velocity above 100 km/s.

We argue that a <span class="hlt">rupture</span> perspective can be helpful for identifying and maintaining a critical potential within nursing research. The paper begins by introducing <span class="hlt">rupture</span> as an inheritance from the French epistemological tradition. It then describes how <span class="hlt">rupture</span> appears in Foucault's works, as both an overall philosophical approach and as an analytic tool in his historical studies. Two examples of analytical applications of <span class="hlt">rupture</span> are elaborated. In the first example, <span class="hlt">rupture</span> has inspired us to make an effort to seek alternatives to mainstream conceptions of the phenomenon under study. In the second example, inspired by Foucault's work on discontinuity, we construct a framework for historical epochs in nursing history. The paper concludes by discussing the potential of the notion of <span class="hlt">rupture</span> as a response to the methodological concerns regarding the use of Foucault-inspired discourse analysis within nursing research. We agree with the critique of Cheek that the critical potential of discourse analysis is at risk of being undermined by research that tends to convert the approach into a fixed method.

It caused enormous loss of life and the virtual destruction of several cities. Despite a very large meizoseismal area, the identification of the causative faults has been hampered by the lack of reliable earthquake locations and conflicting field reports of surface displacement. Using broadband data from global networks of digitally recording seismographs, we analyse broadband seismic waveforms to derive characteristics of the <span class="hlt">rupture</span> process. Complexities in waveforms generated by the earthquake indicate that the <span class="hlt">main</span> <span class="hlt">shock</span> consisted of a tiny precursory subevent followed in the next 20 seconds by a series of four major subevents with depths ranging from 10 to 15 km. The focal mechanisms of the major subevents, which are predominantly strike-slip, have a common nodal plane striking about 285??-295??. Based on the coincidence of this strike with the dominant tectonic fabric of the region we presume that the EW striking planes are the fault planes. The first major subevent nucleated slightly south of the initial precursor. The second subevent occurred northwest of the initial precursor. The last two subevents moved progressively southeastward of the first subevent in a direction collinear with the predominant strike of the fault planes. The offsets in the relative locations and the temporal delays of the <span class="hlt">rupture</span> subevents indicate heterogeneous distribution of fracture strength and the involvement of multiple faults. The spatial distribution of teleseismic aftershocks, which at first appears uncorrelated with meizoseismal contours, can be decomposed into stages. The initial activity, being within and on the periphery of the <span class="hlt">rupture</span> zone, correlates in shape and length with meizoseismal lines. In the second stage of activity the aftershock zone expands and appears to cluster about the geomorphic and geologic features several tens of kilometres from the <span class="hlt">rupture</span> zone. The activity is interpreted as a regional response to quasistatic stress migration along zones of tectonic weakness. The radiated energy of the <span class="hlt">main</span> <span class="hlt">shock</span> and the estimate of seismic moment yields an apparent stress of 20 bars. High apparent stress may be typical of strike slip earthquakes occurring in intracontinental environments undergoing continental collision.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=NASAADS&redirectUrl=http://adsabs.harvard.edu/abs/2012JGRB..11712401C"><span id="translatedtitle"><span class="hlt">Rupture</span> propagation inferred from damage patterns, slip distribution, and segmentation of the 1957 MW 8.1 Gobi-Altay earthquake <span class="hlt">rupture</span> along the Bogd fault, Mongolia</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Choi, Jin-Hyuck; Jin, Kwangmin; Enkhbayar, Dandar; Davvasambuu, Battogtokh; Bayasgalan, Amgalan; Kim, Young-Seog</p> <p>2012-12-01</p> <p>A detailed analysis of the <span class="hlt">rupture</span> patterns and slip changes along the surface <span class="hlt">rupture</span> associated with the 1957 Gobi-Altay earthquake (MW= 8.1) in Mongolia, which occurred along the Bogd left-lateral strike-slip fault, was carried out to better understand segmentation and propagation. The major surface <span class="hlt">ruptures</span> show a simple linear pattern, whereas minor <span class="hlt">ruptures</span> along the major <span class="hlt">ruptures</span>, which are concentrated at <span class="hlt">rupture</span> step overs and tip zones, show complex patterns. In the latter case, their patterns strongly resemble the geometric and kinematic characteristics of previously reported mesoscale fault damage patterns.

Abrupt changes of <span class="hlt">rupture</span> patterns and slip distribution indicate that the coseismic surface <span class="hlt">rupture</span> along the Bogd fault comprises three major segments from west to east, namely, the North-Ih, East-Ih, and North-Baga Bogd segments, and a highly damaged eastern tip zone.

The objectives of this research were to establish what current practice is in the United Kingdom and explore clinicians’ views on proposed further research in this area. This study was registered with the ISRCTN (ISRCTN68273773) as part of a larger programme of research. Methods We report an online survey of current practice in the United Kingdom, approved by the British Orthopaedic Foot and Ankle Society and completed by 181 of its members. A total of ten of these respondents were invited for a subsequent one-to-one interview to explore clinician views on proposed further research in this area. Results The survey showed wide variations in practice, with patients being managed in plaster cast alone (13%), plaster cast followed by orthoses management (68%), and orthoses alone (19%). Within these categories, further variation existed regarding the individual rehabilitation facets, such as the length of time worn, the foot position within them and weight-bearing status. The subsequent interviews reflected this clinical uncertainty and the pressing need for definitive research.

The proposed method has been explained in detail and examined for both intraplate and active regions. Seismotectonic data has been collected for both the regions, and seismic study area (SSA) map was generated for radii of 150, 300, and 500 km. The regional <span class="hlt">rupture</span> character was established by considering percentage fault <span class="hlt">rupture</span> (PFR), which is the ratio of subsurface <span class="hlt">rupture</span> length (RLD) to total fault length (TFL). PFR is used to arrive RLD and is further used for the estimation of maximum magnitude for each seismic source. Maximum magnitude for both the regions was estimated and compared with the existing methods for determining M max values. The proposed method gives similar M max value irrespective of SSA radius and seismicity. Further seismicity parameters such as magnitude of completeness ( M c ), " a" and " b " parameters and maximum observed magnitude ( M {max/obs}) were determined for each SSA and used to estimate M max by considering all the existing methods. It is observed from the study that existing deterministic and probabilistic M max estimation methods are sensitive to SSA radius, M c , a and b parameters and M {max/obs} values. However, M max determined from the proposed method is a function of <span class="hlt">rupture</span> character instead of the seismicity parameters. It was also observed that intraplate region has less PFR when compared to active seismic region.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=PMC&redirectUrl=http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=4306212"><span id="translatedtitle">Spontaneous Forniceal <span class="hlt">Rupture</span> in Pregnancy</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pmc">PubMed Central</a></p> <p>Upputalla, Roshni; Moore, Robert M.; Jim, Belinda</p> <p>2015-01-01</p> <p>Forniceal <span class="hlt">rupture</span> is a rare event in pregnancy.

The most common of these manifestations is coronary heart disease, including stable angina pectoris and the acute coronary syndromes. Atherosclerosis is a lipoprotein-driven disease that leads to plaque formation at specific sites of the arterial tree through intimal inflammation, necrosis, fibrosis, and calcification. After decades of indolent progression, such plaques may suddenly cause life-threatening coronary thrombosis presenting as an acute coronary syndrome. Most often, the culprit morphology is plaque <span class="hlt">rupture</span> with exposure of highly thrombogenic, red cell-rich necrotic core material. The permissive structural requirement for this to occur is an extremely thin fibrous cap, and thus, <span class="hlt">ruptures</span> occur <span class="hlt">mainly</span> among lesions defined as thin-cap fibroatheromas. Also common are thrombi forming on lesions without <span class="hlt">rupture</span> (plaque erosion), most often on pathological intimal thickening or fibroatheromas. However, the mechanisms involved in plaque erosion remain largely unknown, although coronary spasm is suspected. The calcified nodule has been suggested as a rare cause of coronary thrombosis in highly calcified and tortious arteries in older individuals. To characterize the severity and prognosis of plaques, several terms are used. Plaque burden denotes the extent of disease, whereas plaque activity is an ambiguous term, which may refer to one of several processes that characterize progression. Plaque vulnerability describes the short-term risk of precipitating symptomatic thrombosis. In this review, we discuss mechanisms of atherosclerotic plaque initiation and progression; how plaques suddenly precipitate life-threatening thrombi; and the concepts of plaque burden, activity, and vulnerability.

Before cohesive gel silicone implants, <span class="hlt">rupture</span> rates of both saline and silicone breast implants were over 10%. Through an analysis of <span class="hlt">ruptured</span> implants, we can determine the various factors related to <span class="hlt">ruptured</span> implants. Methods We performed a retrospective review of 72 implants that were removed for implant <span class="hlt">rupture</span> between 2005 and 2014 at a single institution. The following data were collected: type of implants (saline or silicone), duration of implantation, type of implant shell, degree of capsular contracture, associated symptoms, cause of <span class="hlt">rupture</span>, diagnostic tools, and management. Results Forty-five Saline implants and 27 silicone implants were used. <span class="hlt">Rupture</span> was diagnosed at a mean of 5.6 and 12 years after insertion of saline and silicone implants, respectively. There was no association between shell type and risk of <span class="hlt">rupture</span>. Spontaneous was the most common reason for the <span class="hlt">rupture</span>. <span class="hlt">Rupture</span> management was implant change (39 case), microfat graft (2 case), removal only (14 case), and follow-up loss (17 case). Conclusions Saline implants have a shorter average duration of <span class="hlt">rupture</span>, but diagnosis is easier and safer, leading to fewer complications. Previous-generation silicone implants required frequent follow-up observation, and it is recommended that they be changed to a cohesive gel implant before hidden <span class="hlt">rupture</span> occurs.

Off-fault yielding and energy absorption in the damage process should reduce the amplitude of the ground motion. However, the reduced elastic moduli in the damaged zone can amplify locally the motion and create a waveguide that may allow the motion to propagate with little geometric attenuation. In addition, the asymmetric damage generated in the in- plane <span class="hlt">rupture</span> mode may produce bimaterial interfaces that can reduce the frictional dissipation and increase the radiation efficiency. Previous studies incorporated plastic yielding in simulations of dynamic <span class="hlt">rupture</span> (Andrews, 1975, 2005; Ben- Zion and Shi, 2005; Templeton et al., 2008) while keeping the elastic moduli unchanged. In this work we examine the dynamics of <span class="hlt">ruptures</span> and generated motion in a model consisting of a frictional fault in a medium governed by a continuum damage rheology that accounts for the evolution of elastic moduli (e.g. Lyakhovsky and Ben-Zion, 2008). We perform numerical simulations based on the Spectral Element Method to study how the parameters of the friction law, damage rheology and background stress control the rate of growth of the off-fault damage zone, the <span class="hlt">rupture</span> speed, the energy partition to various components, and the maximum slip rate and ground motion. We compare the peak motion generated with our damage model to results of analogous simulations using Coulomb plastic yielding. Off-fault damage is of special importance for <span class="hlt">ruptures</span> along faults that separate rocks of different elastic properties, because they can generate asymmetric patterns of material degradation that might be observable in the field. We plan to perform simulations involving velocity-weakening friction and off-fault damage associated with pre-existing bimaterial faults.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=SCIGOV-MAS&redirectUrl=http://academic.research.microsoft.com/Publication/60268360"><span id="translatedtitle"><span class="hlt">Shock</span> absorber</span></a></p> <p><a target="_blank" href="http://academic.research.microsoft.com/">Microsoft Academic Search </a></p> <p>G.

Both laboratory experiments and numerical simulations have shown that the <span class="hlt">rupture</span> process involves an initial quasi-static phase, a subsequent accelerating phase and a <span class="hlt">main</span> dynamic <span class="hlt">rupture</span> phase. During the <span class="hlt">main</span> phase, the <span class="hlt">rupture</span> front propagates at either subshear or supershear velocity, which affects the seismic wave radiation pattern. An examination on what controls the speed is crucial for improvement of earthquake hazard mitigation. Thus We conducted stick-slip experiments on meter-scale Indian gabbro rocks to observe the <span class="hlt">rupture</span> process of the unstable periodic slip events and to measure the <span class="hlt">rupture</span> speed along the fault. The simulated fault plane is 1.5m in length and 0.1m in width and ground by #200-300. The fault is applied at a constant normal stress of 6.7MPa and sheared parallel to the longitudinal direction of the fault at a slip rate of 0.1mm/s and up to a displacement of 40cm. The long, narrow fault geometry leads to in-plane shear <span class="hlt">rupture</span> (mode II). in which the <span class="hlt">rupture</span> front propagates in the direction of slip, which mimics large strike-slip earthquake faulting. Compressional-(Vp) and shear-(Vs) wave velocities of the rock sample are calculated to be 6.92km/s and 3.62km/s, respectively, based on the elastic properties (Young's modulus, 103GPa; Poisson's ratio, 0.331; Shear modulus, 38GPa). 32 biaxial strain gauges for shear strain and 16 single-axis strain gauges for normal strain were attached along the longitudinal direction of the fault at intervals of 5cm and 10cm, respectively. The local strain data were recorded at a sampling rate of 1MHz within 16 bit resolution. Load calls attached outside the fault plane measured the whole normal and shear forces applied on the fault plane, which was recorded by the same recording system. We have confirmed that the <span class="hlt">rupture</span> process of unstable slip events consistsing of 1) an initial quasi-static phase where the slipped area spread on the fault at velocities of less than 10 m/s, 2) an accelerating phase where the <span class="hlt">rupture</span> propagation accelerates up to 100 m/s, and 3) a <span class="hlt">main</span> <span class="hlt">rupture</span> phase where the <span class="hlt">rupture</span> propagates dynamically at elastic wave velocities. These <span class="hlt">rupture</span> nucleation process is consistent with those reported in previous studies. However, between 2) and 3) , we sometimes observed a discontinuity of <span class="hlt">rupture</span> propagation in space and time, which is inconsistent with [Ohnaka & Shen, 1999]. Next, we estimated the <span class="hlt">rupture</span> velocity of the <span class="hlt">main</span> <span class="hlt">rupture</span> phase from spatial-temporal variation in local shear strain associated with the dynamic stress reduction induced by fault slip. While several slip events showed the subshear <span class="hlt">rupture</span> propagation similar to regular natural earthquakes, some were faster than Vs. Such supershear <span class="hlt">rupture</span> propagation has been studied theoretically in 1970's, and reported for large strike-slip faulting earthquakes. Except for Passelègue et al. [2013], however, few laboratory experiments on rocks have confirmed the presence and this study has reproduced supershear <span class="hlt">rupture</span> events along meter-scale fault during stick-slip experiments. We shall discuss the relationship between the <span class="hlt">rupture</span> propagation speed and the stress heterogeneity along the fault monitored by based on the a dense array of local strain gauges.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=PUBMED&redirectUrl=http://www.ncbi.nlm.nih.gov/pubmed/16281033"><span id="translatedtitle">The deterministic nature of earthquake <span class="hlt">rupture</span>.</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Olson, Erik L; Allen, Richard M</p> <p>2005-11-10</p> <p>Understanding the earthquake <span class="hlt">rupture</span> process is central to our understanding of fault systems and earthquake hazards. Multiple hypotheses concerning the nature of fault <span class="hlt">rupture</span> have been proposed but no unifying theory has emerged. The conceptual hypothesis most commonly cited is the cascade model for fault <span class="hlt">rupture</span>. In the cascade model, slip initiates on a small fault patch and continues to <span class="hlt">rupture</span> further across a fault plane as long as the conditions are favourable. Two fundamental implications of this domino-like theory are that small earthquakes begin in the same manner as large earthquakes and that the <span class="hlt">rupture</span> process is not deterministic--that is, the size of the earthquake cannot be determined until the cessation of <span class="hlt">rupture</span>. Here we show that the frequency content of radiated seismic energy within the first few seconds of <span class="hlt">rupture</span> scales with the final magnitude of the event. We infer that the magnitude of an earthquake can therefore be estimated before the <span class="hlt">rupture</span> is complete.

However, recent work has numerically produced <span class="hlt">rupture</span> speeds in this so-called `forbidden zone', that is the region of <span class="hlt">rupture</span> velocities between the Rayleigh wave speed and the shear wave speed, for 3-D simulations. We verify that finding here and further examine the dependence of that behaviour on initial stress and <span class="hlt">rupture</span> initiation parameters. Using a 3-D finite element model for dynamic <span class="hlt">rupture</span> propagation, numerical experiments were performed for different initial stress conditions as well as different size initiation patches and forced <span class="hlt">rupture</span> velocities. It is shown that the initial stress on the fault has a strong influence on the resulting <span class="hlt">rupture</span>, specifically with regards to the distance at which the <span class="hlt">rupture</span> transitions to supershear speeds, the maximum <span class="hlt">rupture</span> velocity attained on the fault, and how rapidly the <span class="hlt">rupture</span> passes through the forbidden zone. It is also demonstrated that for the same initial stress, increasing the size of the nucleation patch or the speed of forced <span class="hlt">rupture</span> can artificially increase the gradient of the <span class="hlt">rupture</span> velocity within the forbidden zone.

Its epicenter was at 18.46 degrees North, 72.53 degrees West, about 25 km WSW of Haiti's capital, Port-au-Prince. The earthquake was relatively shallow (H=13 km, U.S. Geological Survey) and thus had greater intensity and destructiveness. The earthquake occurred along the tectonic boundary between Caribbean and North America plate. This plate boundary is dominated by left-lateral strike slip motion and compression with 2 cm/year of slip velocity eastward with respect to the North America plate. The moment magnitude was measured to be 7.0 (U.S. Geological Survey) and 7.1 (Harvard Centroid-Moment-Tensor (CMT). More than 10 aftershocks ranging from 5.0 to 5.9 in magnitude (none of magnitude larger than 6.0) struck the area in hours following the <span class="hlt">main</span> <span class="hlt">shock</span>. Most of these aftershocks have occurred to the West of the mainshock in the Mirogoane Lakes region and its distribution suggests that the length of the <span class="hlt">rupture</span> was around 70 km. The Harvard Centroid Moment Tensor (CMT) mechanism solution indicates lefth-lateral strike slip movement with a fault plane trending toward (strike = 251o ; dip = 70o; rake = 28o). In order to obtain the spatiotemporal slip distribution of a finite <span class="hlt">rupture</span> model we have used teleseismic body wave and the Kikuchi and Kanamori's method [1]. <span class="hlt">Rupture</span> velocity was constrained by using the directivity effect determined from a set of waveforms well recorded at regional and teleseismic distances [2]. Finally, we compared a map of aftershocks with the Coulomb stress changes caused by the event in the region [3]. [1]- Kikuchi, M., and Kanamori, H., 1982, Inversion of complex body waves: Bull.

I.</p> <p>2013-12-01</p> <p>Since the proposal by Brace and Byerlee [1966] that the mechanism of stick-slip is similar to earthquakes mechanics, many experimental studies have been conducted in order to improve the understanding of earthquakes. Here we report macroscopic stick-slip events in saw-cut Westerly granite samples deformed under controlled upper crustal stress conditions in the laboratory. Experiments were conducted under triaxial loading (?1>?2=?3) at confining pressures (?3) ranging from 10 to 100 MPa. The angle between the fault plane and the maximum stress (?1) was imposed to be equal to 30°. Usual a dual gain system, a high frequency acoustic monitoring array recorded particles acceleration during macroscopic stick-slip events and premonitory background microseismicity. Here, we show that the macroscopic friction coefficient of the fault plane continuously increases with normal stress. At low friction (?<0.6), no background seismicity is recorded. At higher friction however, premonitory activity is systematically observed. An abrupt increase is observed in the second prior to the <span class="hlt">main</span> <span class="hlt">shock</span> and the cumulative moment release rate of the premonitory follows Omori's law. These results suggest that the macroscopic friction also controls the intensity of the premonitory activity in our experiments. In these conditions, Passelègue et al. 2013 have shown that supershear <span class="hlt">ruptures</span> were achievable, at high normal stress. Here, we show that the high frequency content of the particles acceleration spectra also increases with the initial normal stress. The appearance of a peak around 0.1 MHz corresponds to the propagation of a conic wavefront at supershear velocities. In addition, a second high frequency peak, centered around 0.3MHz, appears with increasing cumulative number of stick-slip events. This high frequency radiation could be related to the gouge production and off-fault damage during <span class="hlt">rupture</span> propagation. For the first time, we also record the stress drop dynamically, and show that the dynamic stress drop, measured locally close to the fault plane, is almost total ?<0.15 in the breakdown zone, while the strength recovery to values of ?>0.4 takes a few tens of microseconds only. Our measurements are consistent with flash heating, while stress drops measured at higher normal stress generally reveal a second frictionnal drop, consistent with the onset of melting, which was confirmed by our post-mortem microstructural analysis. Relationships between initial friction, <span class="hlt">rupture</span> velocities, high frequency radiation and stress drop suggest that at high normal stress (i.e. at supershear velocities), the <span class="hlt">rupture</span> processes become more dispersive.

Subject-specific geometries were obtained using ultrasound images and a mesh morphing technique called Free Form Deformation. Tendon material properties were obtained by performing material optimization that compared and minimized difference in uniaxial tension experimental results with model predictions. Our results showed that both tendon geometry and material properties are highly subject-specific.

Radiographic assessment with plain films supplemented by ultrasound and magnetic resonance imaging when the work-up is equivocal further aids diagnosis; however, advanced imaging is often unnecessary in patients with functional extensor mechanism deficits. Acute repair is preferred, and transpatellar bone tunnels serve as the primary form of fixation when the tendon <span class="hlt">rupture</span> occurs at the patellar insertion, with or without augmentation depending on surgeon preference. Chronic tears and disruptions following total knee arthroplasty are special cases requiring reconstructions with allograft, synthetic mesh, or autograft. Rehabilitation protocols generally allow immediate weight-bearing with the knee locked in extension and crutch support. Limited arc motion is started early with active flexion and passive extension and then advanced progressively, followed by full active range of motion and strengthening. Complications are few but include quadriceps atrophy, knee stiffness, and rerupture. Outcomes are excellent if repair is done acutely, with poorer outcomes associated with delayed repair.

The synthetic and sensitivity tests of the Q s determination were carried out accordingly to justify the temporal variation. A Q s value within the hanging wall above the hypocenter was determined to be 157 ± 18 two years following the Chi-Chi earthquake, which is significantly lower than the Q s tomography values of 238 ± 17 and 289 ± 13 prior to and two years after the <span class="hlt">main</span> <span class="hlt">shock</span>, respectively. Similar values using a signal-path Q s analysis from events within the <span class="hlt">ruptured</span> fault zone to stations along the fault were obtained.

Considering the two independent methods in determination of Q s, the reduction in Q s by 89 two years following the Chi-Chi earthquake in both methods is significant. Along with 1 % V s reduction revealed by the analysis of repeating earthquakes our studies suggested possible reduction both in V s and Q s values within the fault zone after the Chi-Chi earthquake.

Three inversion algorithms are applied. First, a conventional non-linear finite fault inversion is conducted to constrain the overall slip history using relatively long period (> 1 s) seismic data. Second, a dynamic finite fault inversion, which approximates the <span class="hlt">rupture</span> as multiple elliptical cracks, is carried out to understand what are the stress and strength conditions on the fault that produces a <span class="hlt">rupture</span> history that is compatible with the observed data. Finally, an iterative Landweber back-projection algorithm is used to constrain the finer spatio-temporal <span class="hlt">rupture</span> history associating with the high frequency radiation. The efforts particularly focus on the initiation stage of the fault <span class="hlt">rupture</span>.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=NASAADS&redirectUrl=http://adsabs.harvard.edu/abs/2013AGUFM.S51B2375M"><span id="translatedtitle"><span class="hlt">Rupture</span> Synchronicity in Complex Fault Systems</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Milner, K. R.; Jordan, T. H.</p> <p>2013-12-01</p> <p>While most investigators would agree that the timing of large earthquakes within a fault system depends on stress-mediated interactions among its elements, much of the debate relevant to time-dependent forecasting has been centered on single-fault concepts, such as characteristic earthquake behavior. We propose to broaden this discussion by quantifying the multi-fault concept of <span class="hlt">rupture</span> synchronicity. We consider a finite set of small, fault-spanning volumes {Vk} within a fault system of arbitrary (fractal) complexity. We let Ck be the catalog of length tmax comprising Nk discrete times {ti(k)} that mark when the kth volume participates in a <span class="hlt">rupture</span> of magnitude > M. The <span class="hlt">main</span> object of our analysis is the complete set of event time differences {?ij(kk') = ti(k) - tj(k')}, which we take to be a random process with an expected density function ?kk'(t). When k = k', we call this function the auto-catalog density function (ACDF); when k ? k', we call it the cross-catalog density function (CCDF). The roles of the ACDF and CCDF in synchronicity theory are similar to those of autocorrelation and cross-correlation functions in time-series analysis. For a renewal process, the ACDF can be written in terms of convolutions of the interevent-time distribution, and many of its properties (e.g., large-t asymptote) can be derived analytically. The interesting information in the CCDF, like that in the ACDF, is concentrated near t = 0. If two catalogs are completely asynchronous, the CCDF collapses to an asymptote given by the harmonic mean of the ACDF asymptotes. Synchronicity can therefore be characterized by the variability of the CCDF about this asymptote. The brevity of instrumental catalogs makes the identification of synchronicity at large M difficult, but we will illustrate potentially interesting behaviors through the analysis of a million-year California catalog generated by the earthquake simulator, RSQSim (Deiterich & Richards-Dinger, 2010), which we sampled at a dozen fault-spanning volumes. At the magnitude threshold M = 7, the ACDF can be well fit by renewal models with fairly small aperiodicity parameters (? < 0.2) for all fault volumes but one (on the San Jacinto fault). At interseismic (Reid) time scales, we observe pairs of fault segments that are tightly locked, such as the Cholame and Carrizo sections of the San Andreas Fault (SAF), where the CCDF and two ACDFs are nearly equal; segments out of phase (Carrizo-SAF/Coachella-SAF and Coachella-SAF/San Jacinto), where the CCDF variation is an odd function of time; and segments where events are in phase with integer ratios of recurrence times (2:1 synchronicity of Coachella-SAF/Mojave-SAF and Carrizo-SAF/Mojave-SAF). At near-seismic (Omori) time scales, we observe various modes of clustering, triggering, and shadowing in RSQSim catalogs; e.g., events on Mojave-SAF trigger Garlock events, and events on Coachella-SAF shut down events on San Jacinto. Therefore, despite its geometrical complexity and multiplicity of time scales, the RSQSim model of the San Andreas fault system exhibits a variety of synchronous behaviors that increase the predictability of large <span class="hlt">ruptures</span> within the system. A key question for earthquake forecasting is whether the real San Andreas system is equally, or much less, synchronous.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=SCIGOV-STC&redirectUrl=http://www.osti.gov/scitech/biblio/21167821"><span id="translatedtitle">Effects of Tube <span class="hlt">Rupture</span> Modeling and Parameters on Analysis of MSGTR Event Progression in PWR</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Jeong, Ji Hwan [Dept of Environmental System, Cheonan College of Foreign Studies, Anseo-dong, Cheonan, Choongnam, 330-705 (Korea, Republic of); Choi, Ki Yong [Thermal-Hydraulic Safety Research Team, Korea Atomic Energy Research Institute, Deogjin-dong, Yusong-gu, Daejeon, 305-353 (Korea, Republic of); Chang, Keun Sun; Kweon, Young Chel [Dept of Mechanical Engineering, Sunmoon University, Tangjeong-myeon, Asan, Choongnam, 336-708 (Korea, Republic of)</p> <p>2002-07-01</p> <p>A multiple steam generator tube <span class="hlt">rupture</span> (MSGTR) event in APR1400 has been investigated using the best estimate thermal hydraulic system code, MARS1.4. The effects of parameters such as the number of <span class="hlt">ruptured</span> tubes, <span class="hlt">rupture</span> location, affected steam generator on analysis of the MSGTR event in APR1400 is examined. In particular, tube <span class="hlt">rupture</span> modeling methods, single tube modeling (STM) and double tube modeling (DTM), are compared. When five tubes are <span class="hlt">ruptured</span>, the STM predicts the operator response time of 2085 seconds before <span class="hlt">main</span> steam safety valves (MSSVs) are lifted. The effects of <span class="hlt">rupture</span> location on the MSSV lift time is not significant in case of STM, but the MSSV lift time for tube-top <span class="hlt">rupture</span> is found to be 25.3% larger than that for <span class="hlt">rupture</span> at hog-leg side tube sheet in case of DTM. The MSSV lift time for the cases that both steam generators are affected (4C5x, 4C23x) are found to be larger than that of the single steam generator cases (4A5x, 4B5x) due to a bifurcation of the primary leak flow. The discharge coefficient of Cd is found to affect the MSSV lift time only for smaller value of 0.5. It is found that the most dominant parameter governing the MSSV lift time is the leak flow rate. Whether any modeling method is used, it gives the similar MSSV lift time if the leak flow rate is close, except the case of both steam generators are affected. Therefore, the system performance and the MSSV lift time of the APR1400 are strongly dependent on the break flow model used in the best estimate system code.

Due to its rarity, the diagnosis may not be immediately considered, and therefore there is a high associated mortality rate for both mother and fetus. Presentation of case We present a case of a 41-year old primigravida who presented to the obstetricians at 22 weeks’ gestation with severe abdominal pain, <span class="hlt">shock</span> and fetal loss. A bleeding renal artery aneurysm was discovered at laparotomy and radiologically coiled with sacrifice of the left kidney. Treatment of a contralateral aneurysm by autotransplantation of the remaining kidney allowed for preservation of residual renal function. Discussion Surgical acute abdominal presentations can be difficult to interpret in pregnant patients. Pregnancy is known to be a contributing risk factor for spontaneous <span class="hlt">rupture</span> of renal artery aneurysms, an otherwise rare mode of aneurysm presentation. Prompt use of imaging to diagnose and treat non-obstetric causes of the acute abdomen should not be delayed because of perceived risks to the fetus. Endovascular arrest of aneurysmal haemorrhage may be more effect in the context of a gravid uterus than surgical management. Conclusion In the <span class="hlt">shocked</span> pregnant patient with an acute abdominal presentation, visceral artery aneurysm <span class="hlt">rupture</span> may be comparatively more common, and should be considered in the absence of other localizing symptoms. Prompt interventional radiological treatment may be lifesaving in such cases.

METHODS: The retrospective analysis was performed by examining the emergency treatment experiences of 60 cases of <span class="hlt">ruptured</span> bleeding in primary hepatocellular carcinoma. The treatment methods included surgical tumour resection, transcatheter arterial embolization (TAE) and non-surgical treatment. Univariate and multivariate analyses were performed to identify the risk factors that impacted 30-d mortality in the research groups. RESULTS: The 30-d mortality of all patients was 28.3% (n = 17). The univariate analysis showed that Child-Pugh C level liver function, <span class="hlt">shock</span>, massive blood transfusion and large tumour volume were risk factors that influenced 30-d mortality. The multivariate analysis showed that <span class="hlt">shock</span> and massive blood transfusion were independent risk factors that impacted the 30-d mortality of surgical resection. As for the TAE patients, larger tumour volume was a risk factor towards prognosis. CONCLUSION: Radical resection and TAE therapy would achieve better results in carefully selected <span class="hlt">ruptured</span> hepatocellular tumours.

P.</p> <p>2013-12-01</p> <p>Increasing evidence indicates that backthrusts may become active during or after megathrust <span class="hlt">ruptures</span> in subduction zones, such as in Chile and Sumatra areas (Melnick et al., 2012; Singh et al., 2011). Previous studies on relevant mechanisms <span class="hlt">mainly</span> focused on the interaction between forethrusts and the megathrust. Here we aim to investigate through dynamic <span class="hlt">rupture</span> simulations how backthrusts may be activated by megathrust <span class="hlt">ruptures</span> in subduction zone environment. Assuming a single backthrust branch, our preliminary results show that the activation of backthrust is difficult if the megathrust <span class="hlt">rupture</span> can easily pass through the fault junction, owing to a quickly established stress shadow zone in the wake of the megathrust <span class="hlt">rupture</span> front. In contrast, if the megathrust <span class="hlt">rupture</span> is arrested or delayed around the junction, a resultant backward stress lobe of the type discussed by Xu and Ben-Zion (2013) can load the backthrust over a considerable amount of time and facilitates <span class="hlt">rupture</span> activation along the backthrust. A number of candidates can serve to arrest or delay megathrust <span class="hlt">ruptures</span>, such as the velocity-strengthening frictional behavior and off-fault weak materials in the shallow portion of subduction zones, fault bend or ramp, and subducted seamount. Moreover, these features are also found capable of generating backthrusts during the long-term quasi-static process, which provide pre-existing weakness to be reactivated by later dynamic <span class="hlt">ruptures</span>. Our results agree, from a different point of view, with the study based on the critical taper theory (Cubas et al., 2013) that an increase of friction towards the trench favors the activation of backthrusts near the up-dip limit of megathrust <span class="hlt">ruptures</span>. The results highlight the role of fault geometric or strength heterogeneities in controlling the strain partitioning on and off the <span class="hlt">main</span> fault plane. Accordingly, activated backthrusts may be treated as markers that reflect the limits of seismogenic zones, and thus may be used to characterize segmentation of subduction zones. Backthrusts can contribute, like forethrusts, to local tsunami generation, intra-plate seismicity, etc., and should be examined in further detail in future studies.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=NASAADS&redirectUrl=http://adsabs.harvard.edu/abs/2013AGUFM.S43A2494U"><span id="translatedtitle">The Great 1933 Sanriku-oki Earthquake: Possible Compound <span class="hlt">Rupture</span> of Outer Trench Slope and Triggered Interplate Seismicity</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Uchida, N.; Kirby, S. H.; Umino, N.; Hino, R.; Okal, E. A.</p> <p>2013-12-01</p> <p>The 1933 Sanriku-oki earthquake offshore northern Honshu, Japan (Mw8.4) is the largest earthquake that occurred outer-rise/outer-trench-slope region. The spatial extent of the aftershocks and possibility of a triggered seismicity was estimated by using modern relocation method and velocity structure. Land-station based hypocenter determination by using 3D velocity structure was firstly applied to the off-Sanriku, near-trench region where systematic hypocenter shifts are recognized in the previous studies. The improvement of hypocenter locations near the trench were confirmed by examinations of recent earthquakes that are accurately located based on OBS data. The earthquakes after the 1933 Sanriku-oki earthquake are located about 200 km long region under the outer trench slope that is separated from the aftershock seismicity under the inner trench slope. The outer-trench-slope earthquakes are shallow (depth <=50km) and has V-shape distribution in the trench-normal cross-section. The aftershock distribution suggests shallow <span class="hlt">rupture</span> area and possibly a compound <span class="hlt">rupture</span> for the 1933 <span class="hlt">main</span> <span class="hlt">shock</span>. We found the V-shaped compound <span class="hlt">rupture</span> model explains better the polarity of Tsunami waves at the Sanriku coast than a single west dipping fault. This indicates that the whole lithosphere is probably not under deviatoric tension at the time of the 1933 earthquake. The occurrence of aftershocks both in outer- and inner trench slope regions was confirmed by the investigation of dominant wave frequency which is seen in the recent precisely located earthquakes in the two regions (Gamage et al., 2009). The earthquakes under the inner trench slope were shallow (depth <=30km) and located where recent activity of interplate thrust earthquakes is high. This suggests the deformation of the 1933 outer-rise earthquake triggered the interplate earthquakes. Recent (2001-2012) seismicity around the source area by the same method show the seismicity at the outer trench-slope region of northern Honshu can be divided into several groups of earthquakes along the trench; one group roughly corresponds to the aftershock region of the 1933 earthquake. Comparison of the 1933 <span class="hlt">rupture</span> dimension based on our relocations with the morphologies of fault scarps in the outer trench slope suggest that the <span class="hlt">rupture</span> was limited by the region where fault scarps are trench parallel and cross cutting seafloor spreading fabric. These suggest bending and structural segmentation largely controls the horizontal and vertical extent of the fault. The re-examined aftershock distribution in this study provides a constraint on the stress state of the subducting plate and water supply to deep earth. They also suggest triggered of interplate seismicity that imply the outer rise /outer trench slope earthquake is closely involved in the earthquake cycle of interplate earthquake.</p> </li> </ol> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_5");'>5</a></li> <li><a href="#" onclick='return showDiv("page_6");'>6</a></li> <li class="active"><span>7</span></li> <li><a href="#" onclick='return showDiv("page_8");'>8</a></li> <li><a href="#" onclick='return showDiv("page_9");'>9</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div><!-- col-sm-12 --> </div><!-- row --> </div><!-- page_7 --> <div id="page_8" class="hiddenDiv"> <div class="row"> <div class="col-sm-12"> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_6");'>6</a></li> <li><a href="#" onclick='return showDiv("page_7");'>7</a></li> <li class="active"><span>8</span></li> <li><a href="#" onclick='return showDiv("page_9");'>9</a></li> <li><a href="#" onclick='return showDiv("page_10");'>10</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div> </div> <div class="row"> <div class="col-sm-12"> <ol class="result-class" start="141"> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=PMC&redirectUrl=http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=4354389"><span id="translatedtitle">A case of abdominal apoplexy because of the <span class="hlt">rupture</span> of the short gastric vessel</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pmc">PubMed Central</a></p> <p>Osunkunle, Olaoluwakitan A.; Al-Shoek, Ihsan</p> <p>2015-01-01</p> <p>Abdominal apoplexy or idiopathic spontaneous intraperitoneal haemorrhage is defined as the presence of free blood within the peritoneal cavity.

The earthquake generated complex body-waveforms varying with azimuth at teleseismic distances. The method of complex body-waveform inversion developed by Kikuchi and Kanamori (1991)was used to infer a source process for the earthquake. Two subevents were necessary to explain the observed seismic records. The inversion result suggests that the Dinar earthquake initiated at the SE end of the Dinar fault with a subevent of seismic moment Mo=0.5×10 18 N m. Six seconds later, the second subevent took place about 10 km to the northwest of the first subevent with a seismic moment a few times larger than the first. The CMT depths of the first and second subevents were found to be 10 and 15 km, respectively. Both subevents had a predominantly normal faulting mechanism with slip-vectors oriented NE-SW, showing good agreement with the velocity-vectors obtained from the recent SLR and GPS studies as well as with the regional stress orientation obtained from geological data. The <span class="hlt">main</span> <span class="hlt">shock</span> was preceded by foreshock activity concentrated at the SE end of the Dinar fault where the first subevent took place, while the aftershock activity was concentrated in the vicinity of the second subevent. The spatial distribution of the foreshock and the aftershock activities and the locations of the subevents suggest that the first subevent broke an asperity and the second subevent broke a barrier on the fault, following the definition by Aki (1984)of an asperity and barrier earthquake model. About 10 km of surface <span class="hlt">ruptures</span> were associated with the earthquake while the estimates yield a <span class="hlt">rupture</span> length of 25 km. The calculated source parameters of the subevents and their locations suggest that the surface <span class="hlt">ruptures</span> were probably associated with the first subevent. The estimates also show that the <span class="hlt">rupture</span> zones of the two subevents overlapped where the maximum vertical displacement was observed.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=NASAADS&redirectUrl=http://adsabs.harvard.edu/abs/2014AGUFMGP23B3684L"><span id="translatedtitle">Fault-rock magnetism from the earth surface trench closed to the Wenchuan Earthquake Surface <span class="hlt">Rupture</span> Zone imply the different slip dynamics</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Liu, D.; Li, H.; Lee, T. Q.; Sun, Z.</p> <p>2014-12-01</p> <p>The 2008 Mw 7.9 Wenchuan Earthquake had induced two major earthquake surface <span class="hlt">rupture</span> zones, including the Yingxiu-Beichuan earthquake fault (Y-B F.) and Guanxian-Anxian earthquake fault (G-A F.) earthquake surface <span class="hlt">rupture</span> zones. This giant earthquake had caused great human and financial loss. After <span class="hlt">main</span> <span class="hlt">shock</span>, the Wenchuan earthquake Fault Scientific Drilling project (WFSD) was co-organized by the Ministry of Science and Technology, Ministry of Land and Resources and China Bureau of Seismology, and this project focused on earthquake fault mechanics, earthquake slip process, fault physical and chemical characteristics, mechanical behavior, fluid behavior, fracture energy, and so on. In this study, the fault-rocks in the two trenches close to the two Wenchuan Earthquake surface <span class="hlt">rupture</span> zone were used to discuss the earthquake slip dynamics, including the Bajiaomiao and Jiulong trenches along the Y-B F. and G-A F. earthquake surface <span class="hlt">rupture</span> zones, respectively. This study also combined with the recent fault-rock magnetism from the earth surface and WFSD-1. The rock magnetism, from the Bajiaomiao trench and other previous researches, shows that the high susceptibility of the fault gouge along the Yingxiu-Beichuan earthquake fault zone was caused by the new-formed ferrimagnetic minerals, such as magnetite and hematite, so the Y-B F. had experienced high temperature and rapid speed thermal pressurization earthquake slip mechanism. The rock magnetism from the Jiulong trench implied that the slightly low average susceptibility of fault gouge was caused by high content of Fe-sulfides than that of fault breccia and Jurassic sandstones, which was possibly induced by earthquake process or earth surface process after the fault rocks exposed to the surface. If the high content of Fe-sulfides was induced by earthquake process, the G-A F. had experienced the low temperature and slow speed machanical lubrication earthquake slip mechanism. The different earthquake slip mechanism was possibly controlled by the deep structure of the two earthquake faults, such as the fault occurrence. The steep dip character of the Y-B F. could be easy to induce high temperature and rapid speed earthquake slip mechanism, while the low dip angle feature of the G-A F. could be easy to induce low temperature and slow speed earthquake slip mechanism.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=SCIGOV-MAS&redirectUrl=http://academic.research.microsoft.com/Publication/23424162"><span id="translatedtitle">Experimental study of organic dust ignition behind <span class="hlt">shock</span> waves</span></a></p> <p><a target="_blank" href="http://academic.research.microsoft.com/">Microsoft Academic Search </a></p> <p>M.

Although the standard management of children with splenic injury is nonoperative, there is scant evidence in the literature to support handling neonates in the same way. We report a case of neonatal splenic <span class="hlt">rupture</span> that was managed nonoperatively. A 3.6-kg full-term female born vaginally became tachycardic and pale on the second day of life. She had a distended abdomen and a hemoglobin of 5.8 g/dL. Her blood pressure remained within normal limits. She was transfused 20 cc/kg packed red blood cells. CT scan showed a grade V splenic <span class="hlt">rupture</span>. Coagulopathy workup was negative. The assumption was that she had a <span class="hlt">ruptured</span> spleen secondary to a traumatic delivery. She remained stable after the transfusion. It took 32 weeks for a CT scan to show complete healing. Traditionally, neonatal splenic <span class="hlt">rupture</span> has been treated with splenectomy or splenorrhaphy. The first case of a neonate to be treated nonoperatively was reported in 2000. Our patient is only the second reported case. We chose to follow her with imaging to document healing and to rule out a tumor, as epidermoid cysts and hemangioendotheliomas can cause neonatal splenic <span class="hlt">rupture</span>.

Due to their steep dip, slip along such structures triggered by a megathrust earthquake may enhance near-field tsunami waves and shorten arrival times. However, motion of splay faults and their role on seismotectonic segmentation has remained elusive due to their predominant offshore location and few historical accounts. Though splay fault slip has been inferred during the 2004 Sumatra and other events, surface <span class="hlt">ruptures</span> triggered by the 1964 M9.2 Alaska earthquake have been the only documented so far. Here we use field, geodetic and InSAR data to document surface fault <span class="hlt">rupture</span> and coastal tilting at Isla Santa Maria (ISM; 37S) during the M8.8 earthquake of February 27, 2010. We integrate the observed deformation with previous knowledge of the regional structure to propose triggering of a splay fault. ISM is 75 km inland from the trench, at the intersection of the Arauco Bay and Santa María fault systems (SMFS), both consisting of blind reverse faults that propagate folds. The SMFS is associated to a cluster of microseismicity extending from the plate interface at 15 km to 2 km depth. An offshore seismic reflection profile across this cluster images a <span class="hlt">main</span> reverse fault with a flat-ramp-flat structure shortcutting to the footwall. The 2010 surface breaks extend across the entire northern part of the island for 900 m, divided in two domains of ENE-WSW oriented structures separated by an E-W striking transfer zone. Each domain consists of faults and fractures with en echelon patterns, with a maximum normal vertical displacement of 80 cm. The geometry of surface <span class="hlt">ruptures</span> is consistent with dextral transtensional kinematics. We associate the surface breaks to transpressional growth of the fault-cored anticline northeast of ISM; transtension at the surface relates to fold bending. Surface <span class="hlt">rupture</span> was accompanied by 1.6-2.2 m of coastal uplift and a northward tilt revealed by ALOS InSAR data, biomarkers, campaign GPS, and leveling of a benchmark. This pattern of tilting mimics that of emerged late Holocene beach ridges, and is rather associated to motion along the Arauco Bay fault. Both systems may have been triggered by the megathrust event. Alternatively, it could arise at the sharp edge of a patch of high megathrust slip. Prominent rush of fluids from the <span class="hlt">rupture</span> started during the Maule earthquake and continued for weeks. A small lake adjacent to the <span class="hlt">rupture</span>, dry during summer droughts, became filled by the offspring. The flat morphology leads to small drainage basins with barely sufficient water to supply inhabitants during dry summer months suggesting that fluids rose through the fault from deeper levels in the crust. The SMFS is associated to the position of a paleo backstop structure, which limited an older deformable domain from the stable continental framework. The SMFS branches upward near the updip limit of the seismogenic zone, where fluids are expelled from mineral transformations. The Maule earthquake may have released trapped fluids at depth, which migrated through the splay fault reducing its friction and facilitating fault slip and surface <span class="hlt">rupture</span>.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=PUBMED&redirectUrl=http://www.ncbi.nlm.nih.gov/pubmed/25577259"><span id="translatedtitle">Linguine sign in musculoskeletal imaging: calf silicone implant <span class="hlt">rupture</span>.</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Duryea, Dennis; Petscavage-Thomas, Jonelle; Frauenhoffer, Elizabeth E; Walker, Eric A</p> <p>2015-08-01</p> <p>Imaging findings of breast silicone implant <span class="hlt">rupture</span> are well described in the literature.

In strike-slip faults model, type of <span class="hlt">rupture</span> propagation and width of shear zone (W) are primary affecting by depth of overburden layer (H), distances of fault slip (Sy).

Comparison surface and profiles structure which were curved faces and cross each other to define 3-D <span class="hlt">rupture</span> and width of shear zone. We found that an increase in fault slip could result in a greater width of shear zone, and proposed a W/H versus Sy/H relationship. Deformation of shear zone showed a similar trend as in the literature that the increase of fault slip resulted in the increase of W, however, the increasing trend became opposite after a peak (when Sy/H was 1) value of W was reached (small than 1.5). The results showed that the W width is limited at a constant value in 3-D models by strike-slip faulting.

There has been no national guidance on the best candidate conditions for newborn screening since the National Academy of Sciences report of 19751 and the United States Congress Office of Technology Assessment report of 1988,2 despite rapid developments since then in genetics, in screening technologies, and in some treatments. Objectives: In 2002, the Maternal and Child Health Bureau (MCHB) of the Health Resources and Services Administration (HRSA) of the United States Department of Health and Human Services (DHHS) commissioned the American College of Medical Genetics (ACMG) to: Conduct an analysis of the scientific literature on the effectiveness of newborn screening.Gather expert opinion to delineate the best evidence for screening for specified conditions and develop recommendations focused on newborn screening, including but not limited to the development of a uniform condition panel.Consider other components of the newborn screening system that are critical to achieving the expected outcomes in those screened. Methods: A group of experts in various areas of subspecialty medicine and primary care, health policy, law, public health, and consumers worked with a steering committee and several expert work groups, using a two-tiered approach to assess and rank conditions. A first step was developing a set of principles to guide the analysis. This was followed by developing criteria by which conditions could be evaluated, and then identifying the conditions to be evaluated. A large and broadly representative group of experts was asked to provide their opinions on the extent to which particular conditions met the selected criteria, relying on supporting evidence and references from the scientific literature. The criteria were distributed among three <span class="hlt">main</span> categories for each condition: The availability and characteristics of the screening test;The availability and complexity of diagnostic services; andThe availability and efficacy of treatments related to the conditions. A survey process utilizing a data collection instrument was used to gather expert opinion on the conditions in the first tier of the assessment. The data collection format and survey provided the opportunity to quantify expert opinion and to obtain the views of a diverse set of interest groups (necessary due to the subjective nature of some of the criteria). Statistical analysis of data produced a score for each condition, which determined its ranking and initial placement in one of three categories (high scoring, moderately scoring, or low scoring/absence of a newborn screening test). In the second tier of these analyses, the evidence base related to each condition was assessed in depth (e.g., via systematic reviews of reference lists including MedLine, PubMed and others; books; Internet searches; professional guidelines; clinical evidence; and cost/economic evidence and modeling). The fact sheets reflecting these analyses were evaluated by at least two acknowledged experts for each condition. These experts assessed the data and the associated references related to each criterion and provided corrections where appropriate, assigned a value to the level of evidence and the quality of the studies that established the evidence base, and determined whether there were significant variances from the survey data. Survey results were subsequently realigned with the evidence obtained from the scientific literature during the second-tier analysis for all objective criteria, based on input from at least three acknowledged experts in each condition. The information from these two tiers of assessment was then considered with regard to the overriding principles and other technology or condition-specific recommendations.

Objectives for this study were to (1) characterize <span class="hlt">shock</span> effects in a complex polymineralic rock with a significant proportion of hydrous ferromagnesian minerals, both as a function of variable <span class="hlt">shock</span> pressure and preshock temperature, and (2) to explore the effects of <span class="hlt">shock</span> impedance contrast between component minerals on the respective abundances and distribution of these features. At any <span class="hlt">shock</span> pressure, the order of decreasing intensity of <span class="hlt">shock</span> metamorphic effects in component phases is: cordierite (Crd)?biotite (Bt)?plagioclase (Pl)?K-feldspar (Kfs)?quartz (Qtz)?garnet (Grt)?orthopyroxene (Opx). Samples <span class="hlt">shocked</span> to pressures below 40 GPa (25 °C) were typically characterized by marked heterogeneous distribution of <span class="hlt">shock</span> effects on both intragranular and intergranular scales. <span class="hlt">Shock</span> heterogeneity is <span class="hlt">mainly</span> attributed to <span class="hlt">shock</span> impedance contrast between contiguous phases, and manifests as <span class="hlt">shock</span> amplification locally where <span class="hlt">shock</span> impedance contrast is greatest, and <span class="hlt">shock</span> suppression where impedance contrast is least.

METHODS: Seventy-nine patients experiencing spontaneous <span class="hlt">rupture</span> of HCC between April 2004 and August 2014 were enrolled in this study. The clinical features, treatment modalities and outcomes were reviewed. The statistical methods used in this work included univariate analysis, Kaplan-Meier survival analysis with log-rank tests, and multivariate analysis using a Cox regression hazard model. RESULTS: Of the 79 patients with HCC <span class="hlt">rupture</span>, 17 (21.5%) underwent surgery, 32 (40.5%) underwent transarterial embolization (TAE), and 30 (38%) received conservative treatment. The median survival time was 125 d, and the mortality rate at 30 d was 27.8%. Multivariate analysis revealed that lesion length (HR = 1.46, P < 0.001), lesion number (HR = 1.37, P = 0.042), treatment before tumor <span class="hlt">rupture</span> (HR = 4.36, P = 0.019), alanine transaminase levels (HR = 1.0, P = 0.011), bicarbonate levels (HR = 1.18, P < 0.001), age (HR = 0.96, P = 0.026), anti-tumor therapy during the follow-up period (HR = 0.21, P = 0.008), and albumin levels (HR = 0.89, P = 0.010) were independent prognostic factors of survival after HCC <span class="hlt">rupture</span>. The Barcelona-Clinic Liver Cancer (BCLC) stage was also an important prognostic factor; the median survival times for BCLC stages A, B and C were 251, 175 and 40 d, respectively (P < 0.001). CONCLUSION: Anti-tumor therapy during the follow-up period, without a history of anti-tumor therapy prior to HCC <span class="hlt">rupture</span>, small tumor length and number, and early BCLC stage are the most crucial predictors associated with satisfactory overall survival. Other factors play only a small role in overall survival.

I.; Ammon, C. J.</p> <p>2004-12-01</p> <p>Earthquakes along subduction zones exhibit spatial and temporal variations in <span class="hlt">rupture</span> processes. Recent studies have demonstrated a systematic decrease in the moment-normalized <span class="hlt">rupture</span> duration of earthquakes with depth along the plate interface. Several shallow earthquakes were observed to exhibit anomalously long <span class="hlt">rupture</span> duration, comparable with the durations of tsunami earthquakes. These observations were suggested to be manifestations of subduction faults with frictional properties capable of generating tsunami earthquakes. The cause of the duration variation was hypothesized to be related to physical changes in properties of subducted sediment. The Philippine trench is a setting where we can study the variations of earthquake source <span class="hlt">rupture</span> processes along the plate interface. The trench is young (< 5 Ma) with a poorly developed accretionary prism. Bathymetry, seismic reflection studies, and offshore drilling show little or no evidence of accretion of the materials from the subducting Philippine Sea plate. Eighty nine possible interplate earthquakes were selected from the Harvard CMT catalogue for the year 1989 to 2001. From these, about 30 events had adequate signal-to-noise ratios and well-constrained mechanisms to warrant further investigation. We used teleseismic broadband records of vertical component waveforms and applied multi-station deconvolution technique to extract the source time function and depth of each event. Our results showed no systematic trend of decreasing source duration with depth at the Philippine trench. The observed moment-normalized durations of all the shallow earthquakes are shorter than tsunami earthquakes. We observed a significant scatter in the relationship between source time and depth, which may reflect heterogeneity of the materials at the trench interface. The thickness of low-rigidity materials in the trench shallow region appears insufficient to affect the <span class="hlt">rupture</span> durations and produce anomalously slow <span class="hlt">ruptures</span>. These null results for the sediment-starved Philippine Trench support the earlier hypothesis that the variations of earthquake duration with depth in other subduction zones is related to sediment properties.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=SCIGOV-MAS&redirectUrl=http://academic.research.microsoft.com/Publication/47884627"><span id="translatedtitle">Bilateral synchronous <span class="hlt">rupture</span> of the quadriceps tendon</span></a></p> <p><a target="_blank" href="http://academic.research.microsoft.com/">Microsoft Academic Search </a></p> <p>P.

The simulations include thermal leakage injection of seed CRs, as well as pre-existing, upstream CR populations. Bohm-like diffusion is assumed.

Detailed numerical solutions are derived for <span class="hlt">shock</span> Lorentz factors {Gamma}{sub u} in the range 6 {<=} {Gamma}{sub u} {<=} 30, using a novel iteration technique solving the hydrodynamics and radiation transport equations (the protons, electrons, and positrons are argued to be coupled by collective plasma processes and are treated as a fluid). The <span class="hlt">shock</span> transition (deceleration) region, where the Lorentz factor {Gamma} drops from {Gamma}{sub u} to {approx}1, is characterized by high plasma temperatures T {approx} {Gamma}m{sub e}c {sup 2} and highly anisotropic radiation, with characteristic <span class="hlt">shock</span>-frame energy of upstream (US) and downstream (DS) going photons of a few x m{sub e}c {sup 2} and {approx}{Gamma}{sup 2} m{sub e}c {sup 2}, respectively.

No high-pressure phases were observed in any of the experimentally <span class="hlt">shocked</span> samples, neither in the deformed nor in the molten regions. Deformation features in Jilin samples <span class="hlt">shock</span>-loaded below 53 GPa are comparable to those found in H- and L-chondrites. The mineral assemblages in the molten regions in the <span class="hlt">shocked</span> Jilin samples are also comparable to those encountered in the heavily <span class="hlt">shocked</span> Yanzhuang (H6) and some Antarctic H-chondrites, but differ considerably from those found in heavily <span class="hlt">shocked</span> Sixiangkou and many other L6 chondrites. <span class="hlt">Shock</span> melt veins in L6 chondrites contain high-pressure polymorphs of olivine, pyroxene, plagioclase and high-pressure liquidus phases, whereas <span class="hlt">shock</span> melt veins in heavily <span class="hlt">shocked</span> H-chondrites contain <span class="hlt">mainly</span> low-pressure mineral assemblages. The differences in the mineral constituents of <span class="hlt">shock</span> melt veins in L- and H-chondrites clearly indicate differences in the <span class="hlt">shock</span> histories of these meteorites.

The duration of the high-pressure regime, the time of the cooling and the P-T regime during the crystallization path, and the post-<span class="hlt">shock</span> temperatures are stringent parameters that control the evolution of the <span class="hlt">shock</span>-induced melt.

After the 2011 Hamadori earthquake, two subparallel faults (the Itozawa and Yunodake faults) were identified by field surveys. The hypocenter was located nearby the Itozawa fault, and it is probable that the Itozawa fault <span class="hlt">ruptured</span> before the Yunodake fault <span class="hlt">rupture</span>. Here, we estimated the source <span class="hlt">rupture</span> process of the 2011 Hamadori earthquake using a model with two subparallel faults based on strong motion data. The <span class="hlt">rupture</span> starting point and <span class="hlt">rupture</span> delay time of the Yunodake fault were determined based on Akaike's Bayesian Information Criterion (ABIC). The results show that the Yunodake fault started to <span class="hlt">rupture</span> from the northern deep point 4.5 s after the Itozawa fault started to <span class="hlt">rupture</span>. The estimated slip distribution in the shallow part is consistent with the surface slip distribution identified by field surveys.

The ?CFF is positive at the <span class="hlt">rupture</span> starting point of the Yunodake fault 4.5 s after the Itozawa fault started to <span class="hlt">rupture</span>; therefore, it is concluded that during the 2011 Hamadori earthquake, the Yunodake fault <span class="hlt">rupture</span> was triggered by the Itozawa fault <span class="hlt">rupture</span>.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=NASAADS&redirectUrl=http://adsabs.harvard.edu/abs/2015EGUGA..17.1210N"><span id="translatedtitle">Particle Acceleration in <span class="hlt">Shock-Shock</span> Interaction</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Nakanotani, Masaru; Matsukiyo, Shuichi; Hada, Tohru</p> <p>2015-04-01</p> <p>Collisionless <span class="hlt">shock</span> waves play a crucial role in producing high energy particles. One of the most plausible acceleration mechanisms is the first order Fermi acceleration in which non-thermal particles statistically gain energy while scattered by MHD turbulence both upstream and downstream of a <span class="hlt">shock</span>. Indeed, X-ray emission from energetic particles accelerated at supernova remnant <span class="hlt">shocks</span> is often observed [e.g., Uchiyama et al., 2007]. Most of the previous studies on <span class="hlt">shock</span> acceleration assume the presence of a single <span class="hlt">shock</span>. In space, however, two <span class="hlt">shocks</span> frequently come close to or even collide with each other. For instance, it is observed that a CME (coronal mass ejection) driven <span class="hlt">shock</span> collides with the earth's bow <span class="hlt">shock</span> [Hietala et al., 2011], or interplanetary <span class="hlt">shocks</span> pass through the heliospheric termination <span class="hlt">shock</span> [Lu et al., 1999]. Colliding <span class="hlt">shocks</span> are observed also in high power laser experiments [Morita et al., 2013]. It is expected that <span class="hlt">shock-shock</span> interactions efficiently produce high energy particles. A previous work using hybrid simulation [Cargill et al., 1986] reports efficient ion acceleration when supercritical two <span class="hlt">shocks</span> collide. In the hybrid simulation, however, the electron dynamics cannot be resolved so that electron acceleration cannot be discussed in principle. Here, we perform one-dimensional full Particle-in-Cell (PIC) simulations to examine colliding two symmetric oblique <span class="hlt">shocks</span> and the associated electron acceleration. In particular, the following three points are discussed in detail. 1. Energetic electrons are observed upstream of the two <span class="hlt">shocks</span> before their collision. These energetic electrons are efficiently accelerated through multiple reflections at the two <span class="hlt">shocks</span> (Fermi acceleration). 2. The reflected electrons excite large amplitude upstream waves. Electron beam cyclotron instability [Hasegawa, 1975] and electron fire hose instability [Li et al., 2000] appear to occur. 3. The large amplitude waves can scatters energetic electrons in pitch angle. The electrons gaining large pitch angles are easily reflected, hence accelerated, when they encounter a <span class="hlt">shock</span>. The reflected electrons can sustain, or probably even strengthen, upstream large amplitude waves. The above series of process may give a positive feedback to the electron acceleration in converging two <span class="hlt">shocks</span>.</p> </li> </ol> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_7");'>7</a></li> <li><a href="#" onclick='return showDiv("page_8");'>8</a></li> <li class="active"><span>9</span></li> <li><a href="#" onclick='return showDiv("page_10");'>10</a></li> <li><a href="#" onclick='return showDiv("page_11");'>11</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div><!-- col-sm-12 --> </div><!-- row --> </div><!-- page_9 --> <div id="page_10" class="hiddenDiv"> <div class="row"> <div class="col-sm-12"> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_8");'>8</a></li> <li><a href="#" onclick='return showDiv("page_9");'>9</a></li> <li class="active"><span>10</span></li> <li><a href="#" onclick='return showDiv("page_11");'>11</a></li> <li><a href="#" onclick='return showDiv("page_12");'>12</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div> </div> <div class="row"> <div class="col-sm-12"> <ol class="result-class" start="181"> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=SCIGOV-STC&redirectUrl=http://www.osti.gov/scitech/servlets/purl/548632"><span id="translatedtitle"><span class="hlt">Shock</span>-initiation chemistry of nitroarenes</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Davis, L.L.

The vortical mode is important since it constitutes the basis of the coherent structures that have been observed to dominate turbulence for low- to moderate-flow speed. Hollingsworth et al. have experimentally investigated the interaction of a cylindrical <span class="hlt">shock</span>-induced starting vortex with a plane normal <span class="hlt">shock</span>, and have shown that the interaction generates a cylindrical acoustic pulse that exhibits a quadrupolar structure consisting of four alternate compression and expansion regions centered around the transmitted vortex.

The multi-parameter borehole system is composed of very wide dynamic range and stable borehole (VBB) broad band seismic sensor, and incorporate 3-D strain meter, tilt meter, and temperature and local hydrostatic pressure measuring devices. All these sensors are installed in 146m-deep borehole. All the sensor outputs are digitized; total of 11*24 bit-channels and 6*20 bit-channels. Real-time data transmission to the <span class="hlt">main</span> server of the Marsite Project at Kandilli Observatory in Istanbul is accomplished. The multi-parameter borehole seismic station uses the latest update technologies and design ideas to record "Earth tides" signals to the smallest magnitude -3 events, as the innovative part of the Marsite Project. Bringing face to face the seismograms of microearthquakes recorded by borehole and surface instruments portrays quite different contents. The shorter recording duration and nearly flat frequency spectrum up to the Nyquist frequencies of borehole records are faced with longer recording duration and rapid decay of spectral amplitudes at higher frequencies of a surface seismogram. The <span class="hlt">main</span> causative of the observed differences are near surface geology effects that mask most of the source related information the seismograms include, and that give rise to scattering, generating longer duration seismograms. In view of these circumstances, studies on microearthquakes employing surface seismograms may bring on misleading results. Particularly, the works on earthquake physics and nucleation process of earthquakes requires elaborate analysis of tiny events. It is obvious from the studies on the nucleation process of the 1999 earthquake that tens of minutes before the major <span class="hlt">rupture</span> initiate noteworthy microearthquake activity happened. The starting point of the 1999 <span class="hlt">rupture</span> was a site of swarm activity noticed a few decades prior the <span class="hlt">main</span> <span class="hlt">shock</span>. Nowadays, analogous case is probable in western Marmara Sea region, prone to a major event in near future where the seismic activity is prevailing along the impending <span class="hlt">rupture</span> zone. Having deployed a borehole system at the eastern end of the Ganos fault zone will yield invaluable data to closely inspect and monitor the last stages of the preparation stage of major <span class="hlt">rupture</span>.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=SCIGOV-STC&redirectUrl=http://www.osti.gov/scitech/servlets/purl/1030718"><span id="translatedtitle">D-Zero Cryostat Supplemental <span class="hlt">Rupture</span> Disc</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Mulholland, G.T.; /Fermilab</p> <p>1987-08-03</p> <p>The common relief and <span class="hlt">rupture</span> disc vent line requires a double disc assembly with vented interspace for accurate disc burst pressures.

Kevlar Composite Overwrapped Pressure Vessel (COPV). The 40-in. vessel was of the same design and approximate age as the STS <span class="hlt">Main</span> Propulsion System (MPS) and Orbiter Maneuvering System (OMS) vessels. The NASA Engineering Safety Center (NESC) assembled a team of experts and conducted an assessment that involved a review of national Kevlar COPY data. During the review, the STS COPVs were found to be beyond their original certification of ten years. The team observed that the likelihood of STS COPV Stress <span class="hlt">rupture</span>, a catastrophic burst before leak failure mode, was greater than previously believed. Consequently, a detailed assessment of remaining stress <span class="hlt">rupture</span> life became necessary. Prior to STS-114, a certification deviation was written for two flights of OV-103 (Discovery) and OV-104 (Atlantis) per rationale that was based on an extensive review of the Lawrence Livermore National Laboratories, COPV data, and revisions to the STS COPV stress levels. In order to obtain flight rationale to extend the certification deviation through the end of the Program, the Orbiter Project Office has directed an interagency COPV team to conduct further testing and analysis to investigate conservatism in the stress <span class="hlt">rupture</span> model and evaluate material age degradation. Additional analysis of stress <span class="hlt">rupture</span> life requires understanding the fiber stresses including stress that occurs due to thru-wall composite compression in COPV components. Data must be obtained at both zero gauge pressure (pre-stress) and at the component operating pressure so that this phenomenon can be properly evaluated. The zero gauge pressure stresses are predominantly a result of the autofrettage process used during vessel manufacture. Determining these pre-stresses and the constitutive behavior of the overwrap at pressure will provide necessary information to better predict the remaining life of the STS COPVs. The primary test objective is obtaining data to verify the hypothesis of a radially oriented thru-thickness stress-riser in the COPV composite whose magnitude is a function of the applied pressure and the load history. The anticipated load dependent response follows from the constitutive behavior of the composite overwrap so data to quantify its nonlinear and time dependent response will be sought. The objective of the Fiber Braggs Gratings (FBGs) were to advance the state-of-the-art by developing techniques using FBG sensors that are capable of assessing stress-<span class="hlt">rupture</span> degradation in Kevlar COPVs in a health monitoring mode (1). Moreover, they sought to answer questions of how embedded sensors affect overall integrity of the structure. And lastly, they sought to provide an important link in the overall stress <span class="hlt">rupture</span> study that will help close the loop on the COPV fabrication process. NDE inspection methods will be used from start to finish and FBG will be an integral link within the overall chain.</p> </li> </ol> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_8");'>8</a></li> <li><a href="#" onclick='return showDiv("page_9");'>9</a></li> <li class="active"><span>10</span></li> <li><a href="#" onclick='return showDiv("page_11");'>11</a></li> <li><a href="#" onclick='return showDiv("page_12");'>12</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div><!-- col-sm-12 --> </div><!-- row --> </div><!-- page_10 --> <div id="page_11" class="hiddenDiv"> <div class="row"> <div class="col-sm-12"> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_9");'>9</a></li> <li><a href="#" onclick='return showDiv("page_10");'>10</a></li> <li class="active"><span>11</span></li> <li><a href="#" onclick='return showDiv("page_12");'>12</a></li> <li><a href="#" onclick='return showDiv("page_13");'>13</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div> </div> <div class="row"> <div class="col-sm-12"> <ol class="result-class" start="201"> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=NASAADS&redirectUrl=http://adsabs.harvard.edu/abs/2015PhFl...27e6101J"><span id="translatedtitle">Analysis of <span class="hlt">shock</span>-wave propagation in aqueous foams using <span class="hlt">shock</span> tube experiments</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Jourdan, G.; Mariani, C.; Houas, L.; Chinnayya, A.; Hadjadj, A.; Del Prete, E.; Haas, J.-F.; Rambert, N.; Counilh, D.; Faure, S.</p> <p>2015-05-01</p> <p>This paper reports experimental results of planar <span class="hlt">shock</span> waves interacting with aqueous foams in a horizontal conventional <span class="hlt">shock</span> tube. Four incident <span class="hlt">shock</span> wave Mach numbers are considered, ranging from 1.07 to 1.8, with two different foam columns of one meter thickness and expansion ratios of 30 and 80. High-speed flow visualizations are used along with pressure measurements to analyse the <span class="hlt">main</span> physical mechanisms that govern <span class="hlt">shock</span> wave mitigation in foams. During the <span class="hlt">shock</span>/foam interaction, a precursor leading pressure jump was identified as the trace of the liquid film destruction stage in the foam fragmentation process. The corresponding pressure threshold is found to be invariant for a given foam. Regarding the mitigation effect, the results show that the speed of the <span class="hlt">shock</span> is drastically reduced and that wetter is the foam, slower are the transmitted waves. The presence of the foam barrier attenuates the induced pressure impulse behind the transmitted <span class="hlt">shock</span>, while the driest foam appears to be more effective, as it limits the pressure induced by the reflected <span class="hlt">shock</span> off the foam front.

The study group consisted of 30 subjects with RTA following falls, rail or road accidents, who were taken by ambulance to the regional trauma centre or directly to forensic pathology. The incidence of RTA in the resident population of 330,000 was in the range 20-30/10(6)/year. There was one survivor in the series, with 24 scene deaths and five deaths en route to hospital. Road accidents were responsible for 57% of incidents. RTA was found in 36% of the fatalities that occurred as a result of car and motorbike accidents.

Originally XBIEM is applicable to non-planar geometry of cracks and medium interfaces, but it has been demonstrated only for a simple planar crack along a bimaterial interface. Here we developed a code to analyse non-planar <span class="hlt">rupture</span> with non-planar interfaces in a mode III problem, and applied it to a dynamic <span class="hlt">rupture</span> problem across a planar bimaterial interface to investigate the effect of medium inhomogeneity. For this purpose, we firstly derived all the displacement and displacement velocity kernels in a unified analytic discretized form, in addition to the stress kernels already derived, necessary for versatile geometry of boundaries (i.e., cracks and interfaces) and checked all the kernel components in the simulation of wave propagation across a non-planar interface cutting a homogeneous medium. Then we validated our code in a wave reflection-transmission problem across a planar bimaterial interface. Secondly, in order to realize the analysis of dynamic <span class="hlt">rupture</span> crossing a bimaterial interface we introduced a new implicit time-stepping scheme for instantaneously interacting boundary elements on the crack and medium interface. Such interactions only appear in the crack's crossing the interface. Otherwise we can use the explicit scheme as employed for BIEM in a homogeneous medium. We validated our numerical code for the crack growth in a homogeneous medium cut with a planar interface and found that our new scheme worked well. Finally, we tackled dynamic <span class="hlt">rupture</span> propagation on a planar fault embedded normal to the planar interface of a bimaterial. Spontaneous <span class="hlt">rupture</span> was allowed not only on the planar <span class="hlt">main</span> fault but also on the interfacial fault and it is controlled by different slip-weakening laws on each of them: each peak strength is individually chosen and its ratio ?=?(interface)/?(<span class="hlt">main</span>) is chosen as one of controlling parameters. Another parameter ? is chosen as a ratio of the shear wave velocities of the bimaterial, ?=?(+)/?(-). Simulations were conducted for hundres of parameter sets of (?, ?). Our results showed two distinct <span class="hlt">rupture</span> processes: a) one is to propagate <span class="hlt">rupture</span> just on the prescribed fault, and b) another is to activate the subsidiary interfacial <span class="hlt">rupture</span>, which finally results in arresting <span class="hlt">rupture</span> on the <span class="hlt">main</span> planar fault. Two processes were found to be clearly divided by a line in the parameter plane (?, ?). With increasing ?, <span class="hlt">rupture</span> tends to stay on the <span class="hlt">main</span> fault with less significant activation of subsidiary interfacial <span class="hlt">rupture</span> and it agrees with our physical anticipation. With increasing ? from 0.7 to 1.4 (one corresponds to homogeneous), the <span class="hlt">rupture</span> processes shift from (a) to (b). This dependency may be understandable in terms of two extreme cases: <span class="hlt">rupture</span> approaching a free surface and <span class="hlt">rupture</span> approaching a fixed boundary. In the former case, the traction approaches zero in the vicinity of free surface, and thus stress does not concentrate along the interface, and vice versa.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=NASAADS&redirectUrl=http://adsabs.harvard.edu/abs/2012cosp...39.1744S"><span id="translatedtitle">Earth's bow <span class="hlt">shock</span>: Power aspects.</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Sedykh, Pavel</p> <p>2012-07-01</p> <p>The process of energy transfer from the solar wind into the magnetosphere, or rather, to convecting magnetospheric plasma, appears to be rather complicated. The bow <span class="hlt">shock</span> front is the <span class="hlt">main</span> converter of solar wind kinetic energy into electromagnetic energy [Ponomarev, Sedykh, J. of Atm. Solar-Terr. Phys. V. 68. 2006; Ponomarev, Sedykh et al., Geomagn. and Aeron., 2009]. Solar wind undergoes significant changes in its parameters during its passing through the bow <span class="hlt">shock</span> front. Indeed, at the bow point, when crossing the front, the magnetic field tangential component and magnetic energy density increase by factors of almost 4 and approximately 15, respectively. In describing the bow <span class="hlt">shock</span>, we followed [Whang, 1987; Ponomarev et al., 2006]. A jump of the magnetic field tangential component when crossing the bow <span class="hlt">shock</span> front means that the front carries an electric current. It is possible to show that electric current is diverging in this layer, that is the front is the generator of the current. Since plasma with magnetic field passes through the bow <span class="hlt">shock</span> front, electric field arises in the front reference system. Thus, the bow <span class="hlt">shock</span> front is a source of electric power. The direction of electric current behind the bow <span class="hlt">shock</span> front depends on the sign of the IMF Bz-component. It is this current which sets convection in motion. Energetically, this external current is necessary for maintaining convection of plasma in the inhomogeneous system (geomagnetosphere). The generator at the bow <span class="hlt">shock</span> front can be a sufficient source of power for supplying energy to substorm processes [Sedykh, Sun and Geosphere, 2011]. The sign of power does not depend on the IMF sign, and energy flux is always directed into the magnetosphere. The magnitude of the power is different and is realized in different regions of the magnetosphere depending on the IMF direction. When the Bz-component is negative, the electric convection field is larger, with the anticonvection field being smaller, than for the same absolute magnitude of the positive IMF Bz-component. Therefore in the first case, the energy dissipates primarily in the auroral zone, while in the second case it does in the polar cap. Electric current from the generator at bow <span class="hlt">shock</span>, changing its sign when the Bz component changes its direction, cannot enter the magnetosphere during the first stage, because a plasma pressure gradient corresponding to the previous value of the electric current is still present there. Only after some time, when the new convection system has restructured the plasma pressure, the current of new direction can enter the magnetosphere.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=NASAADS&redirectUrl=http://adsabs.harvard.edu/abs/2009AGUFM.T43A2040X"><span id="translatedtitle">Dynamic <span class="hlt">rupture</span> on a frictional interface with off-fault damage</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Xu, S.; Ampuero, J. P.; Ben-Zion, Y.; Lyakhovsky, V.</p> <p>2009-12-01</p> <p>The high stress concentration in the front of dynamic <span class="hlt">rupture</span> is expected to produce rock damage (reduction of elastic moduli) in the material surrounding the <span class="hlt">main</span> fault plane. The off-fault yielding of materials and energy absorption in the damage process may reduce the amplitude of near-fault ground motion. However, the local low-velocity zone produced by damage can amplify the motion locally and create a waveguide which will allow the motion to propagate with little geometric attenuation. Moreover, an asymmetric distribution of damage across the fault may produce localized bimaterial interface that could reduce frictional dissipation and increase radiation efficiency. Previous studies incorporated off-fault plastic yielding in simulations of dynamic <span class="hlt">rupture</span> while keeping the elastic moduli unchanged (Andrews, 1975, 2005; Ben-Zion and Shi, 2005; Templeton et al., 2008). In our model the material around the fault is governed by a brittle damage rheology that accounts for spontaneous evolution of the elastic moduli during off-fault inelastic deformation (e.g., Lyakhovsky et al., 1997; Hamiel et al., 2004). The partitioning of elastic strain energy during <span class="hlt">rupture</span> propagation among frictional heat, plastic yielding, rock damage (evolution of elastic moduli), and seismic radiation is examined quantitatively to clarify how the damage generation under different conditions influences the maximum ground motion. Off-fault damage is of special importance for <span class="hlt">ruptures</span> along faults that separate rocks of different elastic properties, because they can generate asymmetric patterns of material degradation that might be observable in the field. <span class="hlt">Ruptures</span> along frictional faults with and without pre-existing contrasts of elastic properties are studied. Results with the damage model are compared to those obtained with elastic and elasto-plastic models. We especially try to clarify effects associated with feedback between the near-<span class="hlt">rupture</span>-tip field and the development of damage, such as the possible emergence of a daughter pulse induced by a dynamic bimaterial effect (coseismic asymmetric reduction of elastic moduli).</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=NASAADS&redirectUrl=http://adsabs.harvard.edu/abs/1993VMHT..........S"><span id="translatedtitle"><span class="hlt">Shock/boundary-layer/shock</span> interactions</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Smith, Virgil K., III</p> <p></p> <p>The <span class="hlt">shock/shock</span> interference phenomena and <span class="hlt">shock</span> wave/boundary layer interactions in hypersonic flight are reviewed.

Formation of energetic spectral tails is possible in a limited energy range for highly perturbed magnetic fields. Cut-offs in the spectra occur at low energies in the resonance range considered. We relate this feature to the structure of the magnetic field downstream of the <span class="hlt">shock</span>, where field compression produces effectively 2D turbulence in which cross-field diffusion is very small. Because of the field compression downstream, the acceleration process is inefficient also in parallel high-$\\gamma$ <span class="hlt">shocks</span> for larger turbulence amplitudes, and features observed in oblique <span class="hlt">shocks</span> are recovered.

Based on detailed mapping, 27 topographic profiles, and field observations, we document the characteristics and slip distribution of the 2002 <span class="hlt">ruptures</span> and describe evidence of pre-2002 <span class="hlt">ruptures</span> on the fault. The 2002 surface faulting produced structures that range from simple folds on a single trace to complex thrust-fault <span class="hlt">ruptures</span> and pressure ridges on multiple, sinuous strands. The deformation zone is locally more than 1 km wide. We measured a maximum vertical displacement of 5.4 m on the south-directed <span class="hlt">main</span> thrust. North-directed backthrusts have more than 4 m of surface offset. We measured a well-constrained near-surface fault dip of about 19?? at one site, which is considerably less than seismologically determined values of 35??-48??. Surface-<span class="hlt">rupture</span> data yield an estimated magnitude of Mw 7.3 for the fault, which is similar to the seismological value of Mw 7.2. Comparison of field and seismological data suggest that the Susitna Glacier fault is part of a large positive flower structure associated with northwest-directed transpressive deformation on the Denali fault. Prehistoric scarps are evidence of previous <span class="hlt">rupture</span> of the Sustina Glacier fault, but additional work is needed to determine if past failures of the Susitna Glacier fault have consistently induced <span class="hlt">rupture</span> of the Denali fault.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=SCIGOV-MAS&redirectUrl=http://www.me.umn.edu/education/courses/me8381/LeeAnnRev2000.pdf"><span id="translatedtitle">BIOPHYSICAL INJURY MECHANISMS IN ELECTRICAL <span class="hlt">SHOCK</span> TRAUMA</span></a></p> <p><a target="_blank" href="http://academic.research.microsoft.com/">Microsoft Academic Search </a></p> <p>Raphael C.

F.</p> <p>2015-06-01</p> <p>The static and transient deformations produced by earthquakes cause density perturbations which, in turn, generate immediate, long-range perturbations of the Earth's gravity field. Here, an analytical solution is derived for gravity perturbations produced by a point double-couple source in homogeneous, infinite, non-self-gravitating elastic media. The solution features transient gravity perturbations that occur at any distance from the source between the <span class="hlt">rupture</span> onset time and the arrival time of seismic P waves, which are of potential interest for real-time earthquake source studies and early warning. An analytical solution for such prompt gravity perturbations is presented in compact form. We show that it approximates adequately the prompt gravity perturbations generated by strike-slip and dip-slip finite fault <span class="hlt">ruptures</span> in a half-space obtained by numerical simulations based on the spectral element method. Based on the analytical solution, we estimate that the observability of prompt gravity perturbations within 10 s after <span class="hlt">rupture</span> onset by current instruments is severely challenged by the background microseism noise but may be achieved by high-precision gravity strainmeters currently under development. Our analytical results facilitate parametric studies of the expected prompt gravity signals that could be recorded by gravity strainmeters.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=DOE-PATENT-XML&redirectUrl=http://www.osti.gov/doepatents/biblio/1136636"><span id="translatedtitle">Biomass <span class="hlt">shock</span> pretreatment</span></a></p> <p><a target="_blank" href="http://www.osti.gov/doepatents">DOEpatents</a></p> <p>Holtzapple, Mark T.; Madison, Maxine Jones; Ramirez, Rocio Sierra; Deimund, Mark A.; Falls, Matthew; Dunkelman, John J.</p> <p>2014-07-01</p> <p>Methods and apparatus for treating biomass that may include introducing a biomass to a chamber; exposing the biomass in the chamber to a <span class="hlt">shock</span> event to produce a <span class="hlt">shocked</span> biomass; and transferring the <span class="hlt">shocked</span> biomass from the chamber.

M.</p> <p>2014-12-01</p> <p>The <span class="hlt">rupture</span> velocities of intermediate- and deep-focus earthquakes --- how they vary between subduction zones, how they vary with depth, and what their maximum values are --- may help constrain the mechanism(s) of the earthquakes. As part of a global study of intermediate- and deep-focus earthquakes, I have used <span class="hlt">rupture</span> directivity to estimate the <span class="hlt">rupture</span> vector (speed and orientation) for 422 earthquakes >70 km depth with MW ?5.7 since 1990. I estimate the <span class="hlt">rupture</span> velocity relative to the local P-wave velocity (vr/?). Since the same method is used for all earthquakes, the results can be readily compared across study areas. The study areas --- Middle America, South America, Tonga-Kermadec, Izu-Bonin-Marianas, and Japan-Kurils-Kamchatka --- include some of the warmest and coldest subduction zones: subducting plate ages range from 9-150 Myr and descent rates range from 1-13 cm/yr. Across all subduction zones and depth ranges, for the 193 earthquakes with observable directivity and well-constrained <span class="hlt">rupture</span> vectors, most earthquakes <span class="hlt">rupture</span> on the more horizontal of the two possible nodal planes. However, the <span class="hlt">rupture</span> vectors appear to be randomly-oriented relative to the slip vector, so the earthquakes span the continuum from Mode II (i.e., parallel slip and <span class="hlt">rupture</span> vectors) to Mode III <span class="hlt">rupture</span> (i.e., perpendicular slip and <span class="hlt">rupture</span> vectors). For this earthquake population, the mean <span class="hlt">rupture</span> velocity is 0.43 vr/? ± 0.14 vr/?. The mean earthquake <span class="hlt">rupture</span> velocities are similar between all subduction zones. Since the local seismic wavespeed is faster in colder subduction zones, absolute <span class="hlt">rupture</span> velocities are faster in colder subduction zones. Overall, the fastest <span class="hlt">rupture</span> velocities exceed the local S-wave speed. The supershear <span class="hlt">ruptures</span> are associated with earthquakes closer to Mode II than Mode III faulting. This is consistent with theoretical calculations, which limit the <span class="hlt">rupture</span> velocity to the S-wave speed for Mode III <span class="hlt">rupture</span> but the P-wave speed for Mode II <span class="hlt">rupture</span>.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=SCIGOV-MAS&redirectUrl=http://academic.research.microsoft.com/Publication/16182054"><span id="translatedtitle">Nonstationary <span class="hlt">shock</span> models</span></a></p> <p><a target="_blank" href="http://academic.research.microsoft.com/">Microsoft Academic Search </a></p> <p>M.

Since repetitive high-frequency operation is indispensable for rapid signal acquisition in beam scattering experiments, the dimensions of the <span class="hlt">shock</span> tube were miniaturized to reduce the evacuation time between shots. The designed <span class="hlt">shock</span> tube is 2-4 mm in diameter and can operate at 0.5 Hz.

To reduce the <span class="hlt">shock</span> attenuation caused by the wall boundary layer, which becomes significant in small-diameter tubes, we developed a high-speed response valve employing the current-loop mechanism. The response time of this mechanism is about 100 ?s, which is shorter than the <span class="hlt">rupture</span> time of conventional diaphragms.

Field investigations indicate that the surface <span class="hlt">rupture</span> of the Kunlunshan earthquake includes en-echelon shear fractures, extensional fractures, tension gashes, thrust fractures and mole tracks on the western segments of the Kunlun fault (2-4). Together with horizontal slickensides on the shear fracture planes, this surface <span class="hlt">rupture</span> pattern reveals left-lateral strike-slip faulting by re-activation of the Kunlun fault, a pre-existing active fault at the southern piedmont of Kunlun Mountains. The mapped surface <span class="hlt">rupture</span> zone comprises two en echelon western and eastern sections with a length between 350 and 426 km. The variation in length is due to uncertainty whether the western section west of Taiyang Lake, southwest of Bukadaban Peak, is tectonic or not and whether this short <span class="hlt">rupture</span> section represents an individual <span class="hlt">rupturing</span> event or only part of a long surface <span class="hlt">rupture</span> zone of a great event.

The strain data was obtained during large-scale biaxial friction experiments conducted at NIED in March 2013. We conducted friction experiments using a pair of meter-scale gabbro rock specimens whose simulated fault area was 1.5m x 0.1m. We applied 2.6MPa normal stress and loading velocity of 0.1mm/s. At the long side of the fault edge, which is parallel to the slip direction, 32 2-component semi-conductor strain gauges were installed at an interval of 50mm and 10mm off the fault. The data are conditioned by high frequency strain amplifiers (<0.5MHz) and continuously recorded at an interval of 1MHz with 16-bit resolution. Many stick slip events were observed and a unilateral <span class="hlt">rupture</span> event was chosen in this analysis that propagated with supershear <span class="hlt">rupture</span> velocity. One of the reasons for this selection was that the strain field ahead of the supershear <span class="hlt">rupture</span> was not contaminated by elastic waves. Focusing on the <span class="hlt">rupture</span> front, stress concentration was observed and sharp stress drop occurred immediately inside the <span class="hlt">rupture</span>. We found that the stress concentration becomes mild as the <span class="hlt">rupture</span> propagates and length of the stress concentration area becomes longer. This observation is quite interesting because in this experiment the <span class="hlt">rupture</span> propagated at a constant speed close to root two times the shear wave velocity and thus a longer stress concentration region suggests more energy dissipation. We could speculate that such longer stress concentration area suggests longer plastic region ahead of the <span class="hlt">rupture</span> (or longer cohesive distance). I.e. the cohesive zone length becomes longer as the <span class="hlt">rupture</span> propagates to maintain constant <span class="hlt">rupture</span> velocity propagation.

P.; Haeussler, P. J.; Seitz, G. G.; Dawson, T. E.</p> <p>2010-12-01</p> <p>A particularly interesting aspect of the 2002 M7.9 Denali fault earthquake was the propagation of the <span class="hlt">rupture</span> from the central Denali fault (CDF) onto the Totschunda fault (TF). New LiDAR data and paleoseismic data provide the basis to more clearly map the structure of the intersection and evaluate controls of fault branching. LiDAR data reveal the CDF-TF intersection is structurally simple. At km 225.7 east of the 2002 epicenter the CDF <span class="hlt">rupture</span> (trending 125°) bends slightly (5°) south and an unruptured fault trace extends eastward from it. Both faults parallel each other for 1.5 km through a 170 m-wide right bend, with the surface traces 40-90 m apart. At km 227.2 the two faults are 65 m apart. Here, the 2002 <span class="hlt">rupture</span>, which is now the TF, diverges southeast (138°); the unruptured fault, which is the eastern Denali fault (EDF), continues eastward with a trend of 121°. There is no step or jump; one fault simply becomes two. 2D analyses and numerical simulations (Kame et al, 2003) suggest three key parameters influence branching: orientation of the principal maximum stress with regard to the <span class="hlt">main</span> fault, <span class="hlt">rupture</span> velocity near the branch point, and orientation of the branch relative to the <span class="hlt">main</span> fault. Varying these, Bhat et al (2004) find that for most simulations the CDF <span class="hlt">rupture</span> continues on the TF. Oglesby et al (2004) performed inverse kinematic and 3D forward dynamic modeling and conclude that a combination of a more favorable orientation to the local stress field and dynamic changes in shear and normal stress favored <span class="hlt">rupture</span> onto the TF. In contrast, we use paleoseismic data to propose that the state of stress at the intersection, as defined by the accumulated strain on each fault (estimated from slip rate and elapsed time since the most recent event), is the primary control of the branching direction and whether propagation beyond the branch point occurs at all. The EDF slip rate is 8.4 (± 2.0) mm/yr; the TF slip rate is 6 (±1.1) mm/yr (Matmon et al, 2006). On the EDF, 17 km east of the intersection, dated peat layers and historical seismicity indicate the most recent surface <span class="hlt">rupture</span> occurred 100-340 years before 2002, with the event closer to the younger date. The penultimate event on the TF occurred 580-700 years before 2002 based on dating at a site 12 km east of the intersection. When the 2002 <span class="hlt">rupture</span> reached the CDF-TF intersection insufficient potential slip (0.6-3.2m) inhibited a continuation on the EDF. The TF, with larger potential slip (2.8-4.9 m), was primed and was triggered. Observed offset in 2002 approached 3m along much of the length of the TF <span class="hlt">rupture</span>; slip in the penultimate event was similar. From paleoearthquake dates on the CDF (AD1430-1650, 930-1300), EDF (AD1660-1900, between or prior to 1320-1450, between or post 720-990), and TF (AD 1302-1422, 612-822) it appears unlikely that the two prior CDF <span class="hlt">ruptures</span> extended beyond the intersection. We suggest that data on event history, slip rate, paleo offsets, and fault geometry, especially on high slip rate-short recurrence interval faults, can be used to assess the likelihood of branching and its direction at other fault intersections such the San Andreas-San Gregorio and the San Andreas-San Jacinto.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=NSDL&redirectUrl=http://www.data.scec.org/Module/s1act02.html"><span id="translatedtitle">What Is an Earthquake?: Fault-<span class="hlt">Rupture</span> Analogies</span></a></p> <p><a target="_blank" href="http://nsdl.org/nsdl_dds/services/ddsws1-1/service_explorer.jsp">NSDL National Science Digital Library</a></p> <p></p> <p></p> <p>This activity has two parts: the first part will demonstrate the weaknesses of simple fault models (like block diagrams) in depicting the process of fault <span class="hlt">rupture</span> accurately; and the second part is centered around a fairly simple animation of <span class="hlt">rupture</span> propagation, seen by an oblique map view, that attempts to show more accurately what we should envision when we think about fault <span class="hlt">rupture</span>.

R.; Jordan, T. H.</p> <p>2013-12-01</p> <p>Forecasting the <span class="hlt">rupture</span> directivity of large earthquakes is an important problem in probabilistic seismic hazard analysis (PSHA), because directivity strongly influences ground motions. We cast this forecasting problem in terms of the conditional hypocenter distribution (CHD), defined to be the probability distribution of a hypocenter given the spatial distribution of fault slip (moment release). The simplest CHD is a uniform distribution for which the hypocenter probability density equals the moment-release probability density. We have compiled samples of CHDs from a global distribution of large earthquakes using three estimation methods: (a) location of hypocenters within the slip distribution from finite-fault inversions, (b) location of hypocenters within early aftershock distributions, and (c) direct inversion for the directivity parameter D, defined in terms of the degree-two polynomial moments of the source space-time function. The data from method (a) are statistically inconsistent with the uniform CHD suggested by McGuire et al. (2002) using method (c). Instead, the data indicate a 'centroid-biased' CHD, in which the expected distance between the hypocenter and the hypocentroid is less than that of a uniform CHD; i.e., the directivities inferred from finite-fault models appear to be closer to bilateral than predicted by the uniform CHD. One source of this discrepancy may be centroid bias in the second-order moments owing to poor localization of the slip in finite-fault inversions. We compare these observational results with CHDs computed from a large set of theoretical <span class="hlt">ruptures</span> in the Southern California fault system produced by the Rate-State Quake simulator (RSQSim) of Dieterich and Richards-Dinger (2010) and discuss the implications for <span class="hlt">rupture</span> dynamics and fault-zone heterogeneities.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=PUBMED&redirectUrl=http://www.ncbi.nlm.nih.gov/pubmed/24679079"><span id="translatedtitle">Isolated unilateral <span class="hlt">rupture</span> of the alar ligament.</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Wong, Sui-To; Ernest, Kimberly; Fan, Grace; Zovickian, John; Pang, Dachling</p> <p>2014-05-01</p> <p>Only 6 cases of isolated unilateral <span class="hlt">rupture</span> of the alar ligament have been previously reported.

After 12 weeks of immobilization in a Guilford brace, MRI showed lessened dens deviation, and the patient attained full and painless neck motion. Including the patient in this case, the 7 patients with this injury were between 5 and 21 years old, sustained the injury in traffic accidents or falls, presented with marked neck pain, and were treated with external immobilization. All patients had good clinical outcome. The mechanism of injury is hyperflexion with rotation. Isolated unilateral alar ligament <span class="hlt">rupture</span> is a diagnosis made by excluding associated fracture, dislocation, or disruption of other major ligamentous structures in the craniovertebral junction. CT and MRI are essential in establishing the diagnosis. External immobilization is adequate treatment.

From a global catalog of tsunami runup observations this variability is greatest for the most frequently occuring tsunamigenic subduction zone earthquakes in the magnitude range of 7 < Mw < 8.5. Variability in local tsunami runup scaling can be ascribed to tsunami source parameters that are independent of seismic moment: variations in the water depth in the source region, the combination of higher slip and lower shear modulus at shallow depth, and <span class="hlt">rupture</span> complexity in the form of heterogeneous slip distribution patterns. The focus of this study is on the effect that <span class="hlt">rupture</span> complexity has on the local tsunami wave field. A wide range of slip distribution patterns are generated using a stochastic, self-affine source model that is consistent with the falloff of far-field seismic displacement spectra at high frequencies. The synthetic slip distributions generated by the stochastic source model are discretized and the vertical displacement fields from point source elastic dislocation expressions are superimposed to compute the coseismic vertical displacement field. For shallow subduction zone earthquakes it is demonstrated that self-affine irregularities of the slip distribution result in significant variations in local tsunami amplitude. The effects of <span class="hlt">rupture</span> complexity are less pronounced for earthquakes at greater depth or along faults with steep dip angles. For a test region along the Pacific coast of central Mexico, peak nearshore tsunami amplitude is calculated for a large number (N = 100) of synthetic slip distribution patterns, all with identical seismic moment (Mw = 8.1). Analysis of the results indicates that for earthquakes of a fixed location, geometry, and seismic moment, peak nearshore tsunami amplitude can vary by a factor of 3 or more. These results indicate that there is substantially more variation in the local tsunami wave field derived from the inherent complexity subduction zone earthquakes than predicted by a simple elastic dislocation model. Probabilistic methods that take into account variability in earthquake <span class="hlt">rupture</span> processes are likely to yield more accurate assessments of tsunami hazards.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=EPRINT&redirectUrl=http://arxiv.org/pdf/cond-mat/0602371v2"><span id="translatedtitle"><span class="hlt">Rupture</span> processes in fiber bundle models</span></a></p> <p><a target="_blank" href="http://www.osti.gov/eprints/">E-print Network</a></p> <p>Per C.

C.</p> <p>2011-12-01</p> <p>Abrupt coastal subsidence induced by the great AD 1700 Cascadia earthquake has been estimated from paleoseismic evidence of buried soils and overlying mud and associated tsunamis deposits. These records have been modeled using a rather uniform <span class="hlt">rupture</span> model, a mirror image of the uniform interseismic fault locking based on modern GPS observations. However, as seen in other megathrust earthquakes such as at Sumatra, Chile, and Alaska, the <span class="hlt">rupture</span> must have had multiple patches of concentrated slip. Variable moment release is also seen in the 2011 Tohoku-Oki earthquake in Japan, although there is only one patch. The use of a uniform <span class="hlt">rupture</span> scenario for Cascadia is due <span class="hlt">mainly</span> to the poor resolving power of the previous paleoseismic data. In this work, we invoke recently obtained more precise data from detailed microfossil studies to better constrain the slip distribution. Our 3-D elastic dislocation model allows the fault slip to vary along strike. Along any profile in the dip direction, we assume a bell-shaped slip distribution with the peak value scaling with local <span class="hlt">rupture</span> width, consistent with <span class="hlt">rupture</span> mechanics. We found that the coseismic slip is large in central Cascadia, and areas of high moment release are separated by areas of low moment release. The amount of slip in northern and southern Cascadia is poorly constrained. Although data uncertainties are large, the coastal variable subsidence can be explained with multiple slip patches. For example, there is an area near Alsea Bay, Oregon (about 44.5°N) that, in accordance with the minimum coseismic subsidence estimated by the microfossil data, had very little slip in the 1700 event. This area approximately coincides with a segment boundary previously defined on the basis of gravity anomalies. There is also reported evidence for the presence of a subducting seamount in this area, and the seamount might be responsible for impeding <span class="hlt">rupture</span> during large earthquakes. The nature of this <span class="hlt">rupture</span> barrier and whether it is a persistent feature are important topics of future research. Our results indicate that there is not always a one-to-one correlation between areas of more complete interseismic locking and larger coseismic slip.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=NASAADS&redirectUrl=http://adsabs.harvard.edu/abs/2014AGUFM.S33F4912Z"><span id="translatedtitle">Automatic Imaging the <span class="hlt">Rupture</span> Process of the 2014 South Napa Earthquake by Iterative Deconvolution and Stacking the Strong-motion Data</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Zhang, Y.; Wang, R.</p> <p>2014-12-01</p> <p>The 2014 South Napa earthquake was well recorded by a densely distributed strong-motion network.

By performing a series of inversions, we have found that networks, with apertures more than 60 km and station spacings less than 10 km, are sufficient to imaging the <span class="hlt">rupture</span> process of the South Napa earthquake. The automatically estimated <span class="hlt">rupture</span> models of different networks are consistent with each other; all of them suggest that the <span class="hlt">ruptures</span> <span class="hlt">mainly</span> propagated to the north and to shallow depths, and formed a unilateral <span class="hlt">rupture</span> event.

D.; Brune, J. N.; Olsen, K. B.</p> <p>2011-12-01</p> <p>The extensional stepover between the Claremont and Casa Loma strands of the San Jacinto Fault in southern California is an area in which complex fault geometry may have a controlling effect on both <span class="hlt">rupture</span> propagation and ground motion. The two <span class="hlt">main</span> strands of the fault in this region are roughly parallel, with an average 4 km separation between them, but smaller complexities within the individual strands may affect <span class="hlt">rupture</span> velocity, slip rate, seismic radiation, and ground motion. The presence of the Farm Road strand, a smaller fault segment between the Claremont and Casa Loma strands, may add further complexity to the <span class="hlt">rupture</span> behavior. We use the three-dimensional finite element method to conduct models of this complex stepover region. We test several different nucleation locations, several initial stress states, and several different seismogenic depths for the Farm Road strand. We then use the outputs of these dynamic models to determine ground motion distributions from these <span class="hlt">ruptures</span>. We find that the nucleation location strongly affects the <span class="hlt">rupture</span>'s ability to jump the stepover; nucleations closer to the overlap are less likely to result in jumping <span class="hlt">rupture</span>. Including the Farm Road strand makes a considerable difference in the <span class="hlt">rupture</span> behavior and ground motion distribution when compared to a model without it, though its contribution is complex. The strength of its effect is variable based on nucleation location, and while its presence does allow <span class="hlt">rupture</span> to jump the larger stepover in stress states that would normally prohibit jumping, it serves to reduce radiated energy and ground motion in stress states that would allow <span class="hlt">rupture</span> to jump in the absence of the smaller strand. The depth of the Farm Road strand has more effect on the <span class="hlt">rupture</span> in the stress state that would not permit jumping in the absence of that segment. These results suggest that hazard associated with <span class="hlt">rupture</span> on the northern San Jacinto depends on specific nucleation point, but also that a seemingly less-permissive stress state for throughgoing <span class="hlt">rupture</span> may ultimately lead to stronger ground motions. This work also continues to highlight the non-monotonic effects of an intermediate fault segment on <span class="hlt">rupture</span> behavior through a larger stepover.</p> </li> </ol> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_11");'>11</a></li> <li><a href="#" onclick='return showDiv("page_12");'>12</a></li> <li class="active"><span>13</span></li> <li><a href="#" onclick='return showDiv("page_14");'>14</a></li> <li><a href="#" onclick='return showDiv("page_15");'>15</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div><!-- col-sm-12 --> </div><!-- row --> </div><!-- page_13 --> <div id="page_14" class="hiddenDiv"> <div class="row"> <div class="col-sm-12"> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_12");'>12</a></li> <li><a href="#" onclick='return showDiv("page_13");'>13</a></li> <li class="active"><span>14</span></li> <li><a href="#" onclick='return showDiv("page_15");'>15</a></li> <li><a href="#" onclick='return showDiv("page_16");'>16</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div> </div> <div class="row"> <div class="col-sm-12"> <ol class="result-class" start="261"> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=SCIGOV-MAS&redirectUrl=http://academic.research.microsoft.com/Publication/52695297"><span id="translatedtitle"><span class="hlt">Shock</span>-wave initiation of heated plastified TATB detonation</span></a></p> <p><a target="_blank" href="http://academic.research.microsoft.com/">Microsoft Academic Search </a></p> <p>Igor Kuzmitsky; Vladimir Rudenko; Leonid Gatilov; Alexandr Koshelev</p> <p>1999-01-01</p> <p>Explosive, plastified TATB, attracts attention with its weak sensitivity to <span class="hlt">shock</span> loads and high temperature stability ( Pthreshold ? 6.5 GPa and Tcrit ? 250 0Q).

This report describes the structural finite element creep <span class="hlt">rupture</span> analysis of the lower head using a temperature transient judged most likely to challenge the structural capacity of the vessel. This evaluation of vessel response to this transient has provided insight into the creep mechanisms of the vessel wall, a realistic mode of failure, and a means by which margin to failure can be evaluated once examination provides estimated maximum wall temperatures. Suggestions for more extensive research in this area are also provided. 6 refs., 15 figs.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=PUBMED&redirectUrl=http://www.ncbi.nlm.nih.gov/pubmed/25279443"><span id="translatedtitle">False vs True <span class="hlt">rupture</span> of membranes.</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Cohain, J S</p> <p>2015-05-01</p> <p>New medical nomenclature: False <span class="hlt">rupture</span> of membranes or False ROM and Double <span class="hlt">rupture</span> of membranes or Double ROM are being introduced into the English language. A single caregiver found about 1% of term births and 10% of term PROM involved False ROM, in which the chorion breaks while the amnion remains intact. Diagnostically, if meconium or vernix is observed, then both the chorionic and amniotic sacs have broken. In the absence of detection of vernix or meconium, an immediate accurate diagnostic test for False ROM is lacking and differentiating between True ROM from False ROM is possible only after leaking stops, which takes hours to days. The obvious benefit of differentiating between 'True' and 'False' ROM, is that in the case of False ROM, the amnion is intact and ascending infections are likely not at increased risk, although research is lacking as to whether False ROM is associated with an increased rate of ascending infection. Three cases of False ROM are presented and avenues for future research are enumerated.

Transmission electron microscopy (TEM) images, however, suggested that the prototype member of the poxviridae, vaccinia virus (VACV), may create its membrane ‘de novo’ with free open ends exposed in the cytosol. Within the frame of the German-wide priority programme we re-addressed the biogenesis and origin of the VACV membrane using electron tomography (ET), cryo-EM and lipid analysis of purified VACV using mass spectrometry (MS). This review discussed how our data led to a model of unconventional membrane biogenesis involving membrane <span class="hlt">rupture</span> and the generation of a single open membrane from open membrane intermediates. Lipid analyses of purified virus by MS suggest an ER origin with a relatively low cholesterol content compared with whole cells, confirming published data. Unlike previous reports using thin-layer chromatography, no depletion of phosphatidylethanolamine was detected. We did detect, however, an enrichment for phosphatidic acid, diacylglycerol and phosphatidylinositol in the virion. Our data are discussed in the light of other pathogens that may require cellular membrane <span class="hlt">rupture</span> during their intracellular life cycle.

We used a pair of Indian gabbro rock samples stacked vertically and applied normal and shear forces. The sliding area between the samples is 1.5m in length and 0.1m in width. We conducted a sequence of experiments using the same rock sample, and before each experiment we removed gouge particles created during the previous experiment by a brush and a cleaner. Here, we show the experiments under constant slip velocity of 0.1mm/s with constant normal stress of 2.7MPa (LB04-003) or 6.7MPa (LB04-005); the final displacement reached 0.04m. We used 44 acoustic sensors (PZT, vertical mode, 0.5MHz resonance frequency), 32 2-comp strain gouges (SGs) for shear strain and 16 1-comp SGs for normal strain measurements, with 48 0.5MHz dynamic SG amplifiers. We also used a 2MN load cell for shear force measurement and three 0.4MN load cells for vertical forces. Data are recorded continuously at an interval of 10MHz for PZT and 1MHz for other sensors. Just after the shear force applied, many stick slip events (SEs) occurred at an interval of a few seconds. By looking carefully at the PZT and SG array data during an SE, we found that one SE consists of many micro stick slip events (MSEs), which can be grouped into two (the former and the latter). These two groups correspond to the acceleration and deceleration stage of the SE. In LB04-005 (6.7MPa normal stress), a clear nucleation phase can be detected that initiated at a narrow area, propagate slowly (~20m/s) and accelerated. Then, a seismic <span class="hlt">rupture</span> started to propagate at a velocity of ~3km/s (subshear) or ~6.5km/s (supershear). Detailed features are shown in Mizoguchi et al. (this meeting). It should be noted that this seismic <span class="hlt">rupture</span> initiated at a narrow area inside the nucleation zone and sometimes after a certain amount of time; it does not seem a smooth transition process from the acceleration to the seismic <span class="hlt">rupture</span> as proposed in Ohnaka and Shen (1999, JGR). In contrast, under low normal stress case (LB04-003, 2.7MPa), there were no visible nucleation phases but a sequence of foreshocks was observed, which was not dominant in LB04-005. The foreshock slip area was typically around 10cm long. Again, we could not see any visible correlation between the location and preceding time of foreshocks and that of seismic <span class="hlt">rupture</span> initiation. By looking at the fault surface topography that was recorded as photograph images before and after the experiment, in the nucleation zone, grooves are not developed, while outside the nucleation area, grooves are well developed. Grooves are caused by the creation of gouge particles during the sliding. It could be interesting to note that outside the groove, the sliding surface looks very smooth and shiny, indicating that this area was polished but did not create gouge particles. Therefore, we might speculate that this shiny fault area is responsible for the initiation phase and when the stress state becomes critical, seismic <span class="hlt">rupture</span> starts around one of the grooves. And in LB04-003, the shiny area might not support the shear stress so that the foreshock releases the strain around the grooves.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=SCIGOV-STC&redirectUrl=http://www.osti.gov/scitech/servlets/purl/6099162"><span id="translatedtitle">Simulations of collisionless <span class="hlt">shocks</span></span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Quest, K.B.</p> <p>1984-01-01</p> <p>A problem of critical importance to space and astrophysics is the existence and properties of high-Mach-number (HMN) <span class="hlt">shocks</span>.

The goal is to provide improved understanding of off-fault yielding during earthquake <span class="hlt">ruptures</span> and its contribution to earthquake physics. A detailed parameter-space study is performed to examine properties of the off-fault plasticity-type yielding under various conditions. The simulation results and theoretical analyses show the following features: (1) the off-fault yielding occurs primarily on the compressional and extensional side when the angle Psi to the fault of the regional maximum compressive stress is low and high, respectively, regardless of the <span class="hlt">rupture</span> mode; (2) the yielding zone thickness and the associated inelastic energy dissipation rate linearly increase with propagation distance for cracks while they approach constants for pulses in quasi-steady state; (3) the intensity of smoothly distributed plastic strain decays with fault normal distance, while for localized plastic strain in narrow bands the average geometric density of the bands decays with fault normal distance; (5) the local angle to the fault of inferred microcracks (aligned parallel to the mode-I type) is shallower and steeper than Psi on the compressional and extensional sides, respectively, and increases with <span class="hlt">rupture</span> speed (in the subshear regime) on the extensional side; (5) the average intensity of plastic strain increases while the yielding zone thickness decreases at greater depth; (6) off-fault yielding contributes to determining <span class="hlt">rupture</span> directivity along a bimaterial fault, leading to reversed and preserved preferred direction when Psi is low and high, respectively; (7) during relatively smooth <span class="hlt">ruptures</span> along typical strike-slip faults, the dominant large-scale secondary shear fractures (on the extensional side) are of the synthetic type, while the minor antithetic set can become prominent with sudden <span class="hlt">rupture</span> deceleration or termination; on the other hand, abrupt <span class="hlt">rupture</span> acceleration leads to relative lack of off-fault yielding in the vicinity of the transition regions. Comparisons to other numerical studies, laboratory experiments, and geological or seismological observations are also presented. The following work replaces plasticity by a more realistic brittle damage rheology that can account for temporal changes of elastic moduli inside the yielding zone, with the goal to explore additional feedback mechanisms between the generation of off-fault yielding and dynamic <span class="hlt">ruptures</span> and their influence on ground motion. The numerical results reveal that off-fault brittle damage can produce dynamic normal stress change along the fault even within an initially homogeneous medium, leading to a possible <span class="hlt">rupture</span> transition from crack-like in the early stage to a mode with a detached pulse front or a train of pulses in the late stage. Moreover, the reduction of elastic moduli inside the yielding zone creates a waveguide that allows the motion to propagate with little geometric attenuation, such as producing trapped wave signals.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=EPRINT&redirectUrl=http://web.gps.caltech.edu/~ampuero/docs/AmpBZ07.pdf"><span id="translatedtitle">Geophys.

The sizes of such events, which account for most of the slip that occurs seismically, appear to vary greatly for different segments of these faults. Repeat time of large <span class="hlt">shocks</span>, coseismic displacement, moment release, <span class="hlt">rupture</span> length, and seismic magnitude appear to correlated with one another and to be a function of the tectonic style of different parts of those fault zones. Tectonic inhomogeneities on a scale of about 1 to 100 km are much larger than displacement in any single seismic event and may be regarded as being invariant in their effects upon earthquake generation over many cycles of large <span class="hlt">shocks</span>. It is this invariance that appears to lead to a given segment of a fault <span class="hlt">rupturing</span> repeatedly in events of nearly the same size. Since repeat time varies, however, for a given segment of a fault, a simple probabilistic approach is used to forecast the likelihood of large future earthquakes for each segment, using as input the time of the last large <span class="hlt">shock</span>, the average recurrence time, and the standard deviation of time intervals between events. Dates of the last large <span class="hlt">shocks</span> are available for most of the segments investigated.

Diagnosis of pancreatic trauma might be difficult, due to unspecific signs and symptoms. The integrity of the <span class="hlt">main</span> pancreatic duct is the crucial point in the management and outcome of patients with pancreatic trauma. PRESENTATION OF CASE The authors report a case of delayed diagnosis after a complete traumatic <span class="hlt">rupture</span> of the <span class="hlt">main</span> pancreatic duct, successfully managed by surgical treatment. The authors performed a laparotomy with complete removal of necrotic pancreatic tissue at the site of <span class="hlt">rupture</span>. The proximal pancreatic stump was hand-sewn with detached stitches and a disposable catheter was positioned into Wirsung's duct, a diversion of the distal stump with a Roux-en-y pancreato-jejunal anastomosis was performed. The postoperative course was uneventful. DISCUSSION Traumatic injuries of the pancreas occur after blunt abdominal traumas or penetrating wounds with a ratio of 3:1. Isolated traumatic injuries of the pancreas are uncommon; and they are usually associated with injuries to other organs. Surgical solutions for the treatment of pancreas lesions vary and it is well known that a surgical procedure performed after a delayed diagnosis is associated with high mortality and morbidity, especially in pancreatic duct <span class="hlt">rupture</span>. CONCLUSION Pancreatic trauma is a diagnostic and therapeutic challenge for the trauma surgeon. The integrity of the <span class="hlt">main</span> pancreatic duct is the most important determinant of outcome after injury to the pancreas and, in Wirsung's duct <span class="hlt">rupture</span>, early surgery may improve it.

D.; McCrory, P. A.; Wech, A.</p> <p>2013-12-01</p> <p>The <span class="hlt">rupture</span> area of the Cascadia megathrust and the areal extent of episodic tremor and slip (ETS) are both now quite well constrained. <span class="hlt">Rupture</span> occurs <span class="hlt">mainly</span> offshore whereas ETS lies <span class="hlt">mainly</span> onshore. The gap between the two is approximately 50 km. The timing of when the fault moves within this gap relative to Cascadia earthquake and ETS cycles is not yet known. The megathrust <span class="hlt">rupture</span> area has been constrained in a recent summary by the locked/transition zones defined from geodetic deformation, the seismic-aseismic transition defined by the temperature on the fault interface, the past <span class="hlt">rupture</span> zone estimated from paleoseismic coastal marsh subsidence, the down-dip change in seismic reflection character of the fault interface, and <span class="hlt">rupture</span> area associations with shelf-slope basins. The depths of the ETS tremor have some uncertainties, as illustrated by differences between several location methods, but are quite well determined in map view. The associated slow slip is less well determined in map view; several estimates locate it slightly seaward of the tremor. The megathrust down-dip limit is convincingly constrained by temperature. However, temperature does not appear to control the up-dip position of ETS as it occurs at variable temperatures along the margin. The best explanation appears to be that the ETS up-dip limit corresponds to the forearc mantle corner. Our compilation of the position of this corner gives general agreement, although there is still much uncertainty. ETS therefore may occur only beneath the forearc mantle with forearc serpentinite and talc likely playing a role. Other hot subduction zones where ETS is separated from the megathrust <span class="hlt">rupture</span> area by a gap, such as SW Japan and Mexico, may provide insights into controls on Cascadia ETS occurrence as well as the timing of fault slip within the gap.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=USGSPUBS&redirectUrl=http://pubs.er.usgs.gov/publication/ofr20071437G"><span id="translatedtitle">Development of Final A-Fault <span class="hlt">Rupture</span> Models for WGCEP/ NSHMP Earthquake Rate Model 2</span></a></p> <p><a target="_blank" href="http://pubs.er.usgs.gov/pubs/index.jsp?view=adv">USGS Publications Warehouse</a></p> <p>Field, Edward H.; Weldon, Ray J., II; Parsons, Thomas; Wills, Chris J.; Dawson, Timothy E.; Stein, Ross S.; Petersen, Mark D.</p> <p>2008-01-01</p> <p>This appendix discusses how we compute the magnitude and rate of earthquake <span class="hlt">ruptures</span> for the seven Type-A faults (Elsinore, Garlock, San Jacinto, S.

P.</p> <p>2014-12-01</p> <p>Most faults have not <span class="hlt">ruptured</span> once historically, let alone repeatedly. Estimating future <span class="hlt">rupture</span> length of an earthquake source has been a challenge since the 1970s when concepts of full and half fault lengths were employed. In the 1980s paleoseismic event timing and observations of slip, coupled with geometric and other physical fault changes, led to concepts of fault segmentation and it's modeling for hazard. The Uniform California Earthquake <span class="hlt">Rupture</span> Forecast 3 (UCERF 3, Field et al., 2014) relaxed segmentation, guided by rules in which a separation distance of ?5km and orientation to Coulomb stress changes at fault junctions are prime factors for allowing fault-to-fault jumps. A set of ~350 fault sections produced ~250K <span class="hlt">ruptures</span> ranging in length from 15 km-1200 km. An inversion provided the rates of these, which range from 102-108 years. Many of the long <span class="hlt">ruptures</span> have exceedingly low individual rates within the UCERF 3 geologic model but are sufficient in number to release cumulative moment that brings the long-term (Myr) and historical (since 1850) MFDs for the California region into close agreement. Does UCERF 3 have too many multi-fault <span class="hlt">ruptures</span>? Since 1850 there have been ~260 surface <span class="hlt">ruptures</span> worldwide in shallow continental crust. 77% are 0-49km; 6% exceed 150km, and the longest is 1906 San Francisco (435-470 km). In California since 1857 there have been 31 surface <span class="hlt">ruptures</span>. 77% are shorter than 49 km. The longest are 1906, 1857 Fort Tejon (297km), and 1872 Owens Valley (108 km). Most long historical strike-slip <span class="hlt">ruptures</span> are continuous and geomorphically well-defined traces with limited geometric changes. In contrast, UCERF3 modeling of the south Hayward, as an example, allows it to participate in <span class="hlt">ruptures</span> that extend to the south ends of the San Andreas or San Jacinto faults (900 km). These include branching (Hayward-Calaveras, San Andreas-San Jacinto) and jumps (Calaveras-San Andreas) on creeping sections of these faults. 5km is the connectivity threshold in UCERF 3 but only 40% of historical <span class="hlt">ruptures</span> have negotiated this distance. There are other controls of <span class="hlt">rupture</span> propagation: frictional properties, <span class="hlt">rupture</span> dynamics, creep, and, as shown by the 2002 Denali-Totschunda <span class="hlt">rupture</span>, the timing of the prior event and level of stress accumulation on adjacent fault sections.

The <span class="hlt">ruptured</span> liver metastasis was successfully treated by transarterial embolization (TAE) followed by hepatic resection. A 65-year-old woman was admitted to our hospital with residual gastric cancer. No liver metastasis was detected by preoperative computed tomography (CT), or ultrasonography, and total gastrectomy was performed. Microscopically, the tumor was a poorly differentiated adenocarcinoma invading no deeper than the subserosa, with positive staining for AFP and positive staining for Ki67 in approximately 80% of the tumor cells. Severe venous and lymphatic involvements were evident. The serum AFP level was 100 ng/ml at 3 weeks after the total gastrectomy, but decreased to 16 ng/ml by the end of postoperative month 3. At 6 months, the patient was referred and readmitted to our hospital with sudden severe pain in the upper abdomen. She was admitted in a state of <span class="hlt">shock</span> with laboratory findings of anemia. A liver tumor surrounded by effusion was detected in segment 8 and diagnosed as a <span class="hlt">ruptured</span> liver metastasis. Emergency arteriography revealed a large hypervascular tumor, and a TAE performed promptly thereafter was successful in improving the blood pressure. A second TAE was performed 2 months after first TAE due to a dramatic elevation of serum AFP to 180,000 ng/ml. The second TAE decreased the patient's serum AFP to 2,200 ng/ml, but the level remained in the abnormal range. A right hepatectomy was performed after confirming the absence of other detectable metastatic tumors. The resected specimen contained a well-defined tumor, measuring 6 x 6 cm that appeared almost necrotic under microscope. Over the 6 years since the hepatectomy, no recurrence has appeared and serum AFP has remained within the normal range.

For this reason, recently, simplified schemes of the <span class="hlt">rupture</span> process have been proposed, while not providing details it can recover their <span class="hlt">main</span> characteristics. In this work we propose a modification of the Cotton & Campillo (1995) inversion scheme, while unlike considering the problem as a "<span class="hlt">rupture</span> process tomographic inversion", we invert the <span class="hlt">main</span> characteristics assuming simplified geometries (ellipses). Based on the work quoted, the direct problem is reparameterized including one or two ellipses in which the maximum displacement is distributed. For the first ellipse, the position of the center within the fault plane, the major and minor semi-axis are inverted. For the second one we invert the position with respect to the first ellipse and the two semi-axis. To avoid the linearization of the problem, we use a simulated annealing scheme for inversion. When there is not enough evidence of the proper fault plane, we perform an inversion for the two nodal planes published to solve the ambiguity between the auxiliary plane and the fault plane that a point source inversion schemes involve. We tested our method for the well studied earthquake September 30th 1999 Oaxaca (Mw=7.5) (e.g. Hernandez et al., 2001) which is one of the intraslab earthquakes within the Northamerican Plate of moderate magnitude and well recorded. The scheme is evaluated as well with the data generated by the "Escenario 2011" framework for an hypothetical earthquake in Guerrero, Mexico. Results will give us the opportunity to evaluate their later routinary implementation to the earthquakes occurring within Mexico.</p> </li> </ol> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_13");'>13</a></li> <li><a href="#" onclick='return showDiv("page_14");'>14</a></li> <li class="active"><span>15</span></li> <li><a href="#" onclick='return showDiv("page_16");'>16</a></li> <li><a href="#" onclick='return showDiv("page_17");'>17</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div><!-- col-sm-12 --> </div><!-- row --> </div><!-- page_15 --> <div id="page_16" class="hiddenDiv"> <div class="row"> <div class="col-sm-12"> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_14");'>14</a></li> <li><a href="#" onclick='return showDiv("page_15");'>15</a></li> <li class="active"><span>16</span></li> <li><a href="#" onclick='return showDiv("page_17");'>17</a></li> <li><a href="#" onclick='return showDiv("page_18");'>18</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div> </div> <div class="row"> <div class="col-sm-12"> <ol class="result-class" start="301"> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=NIH-MEDLINEPLUS&redirectUrl=http://kidshealth.org/parent/infections/bacterial_viral/toxic_shock.html"><span id="translatedtitle">Toxic <span class="hlt">Shock</span> Syndrome (For Parents)</span></a></p> <p><a target="_blank" href="http://medlineplus.gov/">MedlinePLUS</a></p> <p></p> <p></p> <p>...

L.; Stewart, S. T.; Weiss, b. P.</p> <p>2005-01-01</p> <p>Maps of the remanent magnetic field of Mars show demagnetized zones within and around giant impact basins. It is likely that vast regions of the Martian crust were demagnetized due to a <span class="hlt">shock</span>-induced phase change or magnetic transition of magnetic minerals in the crust. This hypothesis is supported by the fact that around the Hellas and Argyre basins, the edges of the unmagnetized zones roughly correspond with peak <span class="hlt">shock</span> pressure contour lines of a few GPa. Although pyrrhotite is not a major carrier of magnetization in the Earth s crust, it is a common phase in Martian meteorites and may be an important carrier in the Martian crust.

Design Prospective study. Animals 68 clinically normal dogs,,18 dogs that were presented to the ER deemed to be in <span class="hlt">shock</span> and 19 dogs presenting to the ER not deemed to be in <span class="hlt">shock</span>. Setting University teaching hospital. Interventions Peripheral or central venous blood sampling. Measurements and <span class="hlt">Main</span> Results Heart rate and SBP were recorded on simulated presentation (healthy dogs), and emergency presentations for both dogs deemed to be in <span class="hlt">shock</span> and dogs not deemed in <span class="hlt">shock</span>. Dogs in <span class="hlt">shock</span> had a median SI of 1.37 (0.87–3.13), which was significantly higher than both other groups; dogs not deemed in <span class="hlt">shock</span> had median SI 0.73 (0.56–1.20), P<0.0001 and healthy dogs had median SI 0.78 (0.37–1.30) P<0.0001), respectively. Receiver operator characteristic curve analysis suggested a SI cut-off of 1.0, yielding an area under the receiver operator characteristic (AUROC) of 0.89 (Specificity (Sp) 89, Sensitivity (Sn) 90) when comparing dogs deemed in <span class="hlt">shock</span> with healthy dogs, and 0.92 (Sp 95, Sn 89) when comparing dogs in <span class="hlt">shock</span> with to dogs not deemed in <span class="hlt">shock</span>. Conclusions The SI is an easy and non-invasive patient parameter that is higher in dogs that are deemed to be in <span class="hlt">shock</span> than both healthy dogs and dogs presented as emergencies but not deemed to be in a state of <span class="hlt">shock</span>.

The authors have demonstrated that the potential extent of inundation will be significantly underestimated if <span class="hlt">rupture</span> complexity is ignored. For local tsunami it has also been shown that for a target site a strict proportionality between earthquake moment magnitude and inundation extent does not exist. The <span class="hlt">main</span> difficulty in including the effects of <span class="hlt">rupture</span> complexity in Probabilistic Tsunami Hazard Assessment (PTHA) for local and regional tsunami lies in the fact that calculations to full inundation need to solve non-linear wave equations. These calculations are so computationally expensive that simulating a statistically significant number of scenarios becomes impractical. The hazard assessment process thus requires a de-aggregation procedure that can rely on simulations based on the linear wave equations alone, to identify scenarios significant enough to be considered for full inundation modelling. We correlate properties of the offshore wave field derived from linear simulations with the extent of inundation derived from non-linear tsunami simulations, allowing us to reduce non-linear calculations in our hazard assessment to a practical number. The effect of <span class="hlt">rupture</span> complexity on the tsunami wave field is routinely considered in tsunami forecasting for distant and regional sources. Source models are inverted from DART buoy readings as soon as this information becomes available. However, depending on the location of the earthquake causing the tsunami, DART buoy information will not be provided immediately after the event, which poses a challenge to tsunami forecasting for local and regional sources. We propose a concept of tsunami forecasting for regional tsunami, which also provides probabilistic hazard assessment for the event in question. This approach considers <span class="hlt">rupture</span> complexity and other uncertainties in the time period between detection of the tsunamigenic earthquake and the delivery of forecasts based on DART buoy information.

Thus, software that calculates the tsunami wave field in supra real-time (much faster than the physical manifestation of the tsunami) needs to be employed.

The critical length and critical <span class="hlt">rupture</span> velocity of the transition scale depend inversely on the normal stress; while the characteristic time is independent of the normal stress.

We provide detailed observation of the wavefield radiated by the barrier, and compare it to the wavefield radiated by a kink.

Martin</p> <p>2014-05-01</p> <p>Broadband ground motion simulations, with frequencies up to 10Hz, are important for engineering purposes, in particular for seismic hazard assessment for critical facilities. One problem in such simulations is the generation of high frequency radiation emitted during the dynamic <span class="hlt">rupture</span> process. Ad-hoc kinematic <span class="hlt">rupture</span> characterizations can be tweaked through empirical models to radiate over the desired frequency range, but their physical consistency remains questionable. In contrast, for physically self-consistent dynamic <span class="hlt">rupture</span> modeling, controlled by friction, material parameters and the adopted physical laws, the mechanism that may lead to appropriate high-frequency radiation require heterogeneity in friction, stress, or fault geometry (or even all three quantities) at unknown but small length scales. Dunham at al. (2011) studied dynamic <span class="hlt">rupture</span> propagation on rough faults in 2D, and described how fault roughness excites high-frequency radiation. In our study, we focus on the interaction of the dynamic <span class="hlt">rupture</span> with small-scale heterogeneities on planar faults in 3D. We study effects of the interaction of dynamic <span class="hlt">rupture</span> with 1) small-scale heterogeneities in the medium (that is, randomized 3D wave speed and density variations), and 2) small-scale heterogeneities in the frictional parameters. Our numerical results show significant variations in <span class="hlt">rupture</span> velocity or peak slip velocity if small-scale heterogeneities are present. This indicates that the dynamic <span class="hlt">rupture</span> is sensitive to both types of spatial inhomogeneity. At the same time we observe that the resulting near-source seismic wave fields are not very sensitive to these <span class="hlt">rupture</span> variations, indicating that wavefront healing effects may "simplify" the complex seismic radiation once the waves propagated several wave-lengths away from the fault.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=NASAADS&redirectUrl=http://adsabs.harvard.edu/abs/2014ShWav..24..365D"><span id="translatedtitle">Area change effects on <span class="hlt">shock</span> wave propagation</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Dowse, J.; Skews, B.</p> <p>2014-07-01</p> <p>Experimental testing was conducted for a planar <span class="hlt">shock</span> wave of incident Mach number propagating through one of three compound parabolic profiles of 130, 195 or 260 mm in length, all of which exhibit an 80 % reduction in area.

The question addressed was whether conservative or surgical management would result in better outcomes in patients presenting with left ventricular free wall <span class="hlt">rupture</span> (LVFWR) following acute myocardial infarction. Surgical techniques involved were infarctectomy + patch repair, suturing of an overlay patch to the defect, patch-and-glue repair and so on, on or off cardiopulmonary bypass. A total of 210 papers were found using the reported searches, of which 10 represented the best evidence to answer the clinical question. The authors, date, journal, study type, population, <span class="hlt">main</span> outcome measures and results were tabulated. The studies found analysed the outcome related to conservative and surgical approaches plus the effects of cardiopulmonary bypass circuit and systemic heparinization on bleeding around the peri-infarct myocardial tissue in the surgical group.

As we have shown there, with the introduction of appropriate particle invariants and the use of Liouville's theorem one can get explicit solutions for the resulting total downstream pressure by adding up from partial pressure contributions of solar wind protons, solar wind electrons and pick-up protons.

The time variations of the <span class="hlt">shock</span> strength obtained from numerical simulation, experiment, and theoretical estimation show the desired converging effect in the <span class="hlt">shock</span> tube test section. Particular emphasis is then placed on the problem of <span class="hlt">shock</span>-interface interaction induced by cylindrical converging <span class="hlt">shock</span> waves. For this purpose, membrane-less gas cylinder is adopted to form the interface between two different fluids while the laser sheet technique to visualize the flow field. The result shows that it is convenient to perform such experiments in this facility.

The use of radiofrequency ablation (RFA) in recent years has enriched the armamentarium for hemostasis of spontaneously <span class="hlt">ruptured</span> HCCs but its results have not been documented. This study investigated the prognosis and outcome of spontaneous <span class="hlt">rupture</span> of HCC as well as the results of using RFA for hemostasis. Patients and method From January 1991 to December 2010, 5283 patients were diagnosed with HCC at our hospital, and 189 of them had spontaneous <span class="hlt">rupture</span> of HCCs. They were grouped under two periods: period 1, 1991–2000, n?=?70; period 2, 2001–2010, n?=?119. RFA was available in period 2 only. Results Hepatitis B virus infection was predominant in both periods. Surgical hemostasis was <span class="hlt">mainly</span> achieved by hepatic artery ligation in period 1 and by RFA in period 2. The 30-day hospital mortality after surgical treatment was 55.6% (n?=?18) in period 1 and 19.2% (n?=?26) in period 2 (p?=?0.012). Multivariate analysis identified 4 independent factors for better overall survival, namely, hemostasis by transarterial chemoembolization (hazard ratio 0.516, 95% confidence interval 0.354–0.751), hemostasis by RFA (hazard ratio 0.431, 95% confidence interval 0.236–0.790), having surgery as a subsequent treatment (hazard ratio 0.305, 95% confidence interval 0.186–0.498), and a serum total bilirubin level <19 umol/L (hazard ratio 1.596, 95% confidence interval 1.137–2.241). Conclusion The use of RFA for hemostasis during laparotomy greatly reduced the hospital mortality rate when compared with conventional hepatic artery ligation.

The <span class="hlt">main</span> process that takes place at the collisionless <span class="hlt">shock</span> is the redistribution of the energy of the directed plasma motion to the plasma thermalization and acceleration of a part of particles to high energies. The <span class="hlt">shocks</span> are often associated with high-frequency (several Hz) wave packets in both upstream and downstream regions. These waves could be resolved only in fast magnetic field data because the time resolution of plasma instruments is often insufficient for their detection. The BMSW instrument onboard the Spektr-R spacecraft measures solar wind parameters with a resolution of 32 ms and open new ways to a detailed analysis of these waves. In this paper, we compare the waves in regions adjacent to interplanetary <span class="hlt">shocks</span> observed in course of the 2011-2013 years and with a set of bow <span class="hlt">shock</span> crossings associated with wave activity. Since the magnetometer onboard Spektr-R is not in operation, we compare BMSW observations with Wind fast magnetic field measurements. We analyze differences in the ion structure of low-Mach number fast forward interplanetary <span class="hlt">shocks</span> and bow <span class="hlt">shocks</span> (as representatives of fast reverse high-Mach number <span class="hlt">shocks</span>).

R. Gomez; A. M. Turner; V. Vitelli</p> <p>2012-08-01</p> <p>The confining pressure $P$ is perhaps the most important parameter controlling the properties of granular matter. Strongly compressed granular media are, in many respects, simple solids in which elastic perturbations travel as ordinary phonons. However, the speed of sound in granular aggregates continuously decreases as the confining pressure decreases, completely vanishing at the jamming-unjamming transition. This anomalous behavior suggests that the transport of energy at low pressures should not be dominated by phonons. In this work we use simulations and theory to show how the response of granular systems becomes increasingly nonlinear as pressure decreases. In the low pressure regime the elastic energy is found to be <span class="hlt">mainly</span> transported through nonlinear waves and <span class="hlt">shocks</span>.

The differential diagnosis weighs on treatment that ranges between close monitoring, splenorrhaphy, splenic conservation and splenectomy. We report a case of an 63-year-old man presenting with acute atraumatic left upper quadrant pain. Preliminary diagnosis was subsequently determined to be a hematoma secondary to OSR.

G.</p> <p>2015-04-01</p> <p><span class="hlt">Rupture</span> directivity of earthquake sources is one of the most important aspects to emerge from full slip distribution as well as the <span class="hlt">rupture</span> size, <span class="hlt">rupture</span> velocity and identification of <span class="hlt">main</span> slip patches. However, interpretations from a single best slip model that fits the data may be wrong, since the intrinsic non-uniqueness of the extended fault inversion persists. For a solution set, a classification of slipmaps according to any appropriate similarity may help us to interpret the inversion result and to propose different hypotheses for the source process. We apply a Popperian inversion strategy that involves the generation of a representative set of slip distributions, comparison of the corresponding forward predictions to the recorded data, and the generation of the solution to the inverse problem as an assembly of all those trial models that have not been falsified on account of unacceptable fits. Then, we propose to analyze <span class="hlt">rupture</span> directivity resolution by calculating the centroids for each slipmap of this solution set. Thereby we obtain the "directivity rose" of an earthquake according to rake and amplitudes of each directivity vector. This result permits to define directivity slipmaps families and to evaluate possible ambiguities. For a feasibility study, we selected an earthquake with well-defined and restricted directivity as the 2011 Mw 5.2 Lorca (Spain) mainshock. Also we analyze the Mw 4.6 foreshock to compare possible similarities. First, in both cases we have obtained Apparent Source Time Functions (ASTF) from deconvolution in the frequency domain using the greatest aftershock (Mw 3.9) as empirical Green's functions. The apparent durations fit an asymmetric bilateral <span class="hlt">rupture</span> with <span class="hlt">rupture</span> propagation in direction SW for mainshock and foreshock. Second, we use an inversion scheme based on a global search among precalculated slipmaps in order to fit the ASTFs. The slip velocity function is fixed and the inversion is carried out for various fixed values of <span class="hlt">rupture</span> velocity. The best results suggest a high <span class="hlt">rupture</span> velocity of 3.25 km/s for the mainshock and 2.75 km/s for the foreshock. The peak slips were about 31 and 7 cm for mainshock and foreshock respectively, considering an average slipmap from solution set. In both earthquakes, slipmaps show one asperity located SW of the hypocenter. These <span class="hlt">rupture</span> similarities are probably introduced by the frictional properties of the rocks in Alhama de Murcia Fault. Finally, <span class="hlt">rupture</span> directivity resolution reveals a setting similar as obtained from fitting only apparent durations, resulting in a single directivity family. The two events present <span class="hlt">rupture</span> propagation towards the town of Lorca. Considering the slipmaps with amplitude greater than 0.5 km for the directivity vectors, we observe a directivity further south increasing the coincidence with the Lorca direction. The same results are obtained when analyzing the set of solutions with the largest slip above a certain fraction of the peak slip to calculate the centroids. This resolution test clearly indicates the magnitude and direction of the <span class="hlt">rupture</span> propagation and evaluates effectively the validity of interpretations from source models.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=NIH-MEDLINEPLUS&redirectUrl=http://www.nlm.nih.gov/medlineplus/ency/article/000653.htm"><span id="translatedtitle">Toxic <span class="hlt">shock</span> syndrome</span></a></p> <p><a target="_blank" href="http://medlineplus.gov/">MedlinePLUS</a></p> <p></p> <p></p> <p>... by a toxin produced by some types of Staphylococcus bacteria.

Relatively little information on the effects of phosphorus has been published, and the available information is contradictory. However, phosphorus in superalloys is generally considered detrimental, and by specification is controlled to a low maximum value (0.015% max, for example, in AMS5662 E).

An increasing number of seismological methods have been developed to determine <span class="hlt">rupture</span> parameters, such as length, velocity and propagation direction, especially since the occurrence of the Sumatra-Andaman earthquake that resulted in a devastating tsunami in the Indian Ocean region. Here, we present a new method to follow the <span class="hlt">rupture</span> process in near real time by a polarization analysis of local and regional P phases that permits a faster determination of <span class="hlt">rupture</span> properties than using teleseismic records. The new technique has the capability to provide detailed information in less than 10 min. Originally, the method stems from a single-station earthquake location method and is expanded here to monitor P-phase polarization variations through time. As the earthquake source moves away from the hypocentre, the backazimuth of an incoming P phase is expected to change accordingly. With polarization analysis we may be able to monitor the temporal change in P-wave backazimuth to follow the <span class="hlt">rupture</span> process in near real time. Three component P phases are scanned to determine the azimuthal variation as a function of time. The backazimuth of a moving <span class="hlt">rupture</span> front is determined by the first eigenvector of the covariance matrix. The linearity of the particle motion is used as a measure of the quality of the data. Seismic stations at local and regional distances (?) are used. We tested the new method with a theoretical simulation and observed seismograms of the Sumatra-Andaman earthquake (2004 December 26, Mw= 9.3), and we were able to follow the <span class="hlt">rupture</span> for the first 200 s. For larger <span class="hlt">ruptures</span>, stations at more than 30° epicentral distances would be required. The method is also successfully applied to the Wenchuan earthquake (2008 May 12, Mw= 8.0).</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=PUBMED&redirectUrl=http://www.ncbi.nlm.nih.gov/pubmed/26015380"><span id="translatedtitle">[Analysis of <span class="hlt">Rupture</span> during Follow-up of Unruptured Aneurysm].</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Koyama, Shinya; Inoue, Mizuho; Uchida, Hiroki; Niizuma, Kuniyasu; Saito, Atsushi; Kon, Hiroyuki; Sasaki, Tatsuya; Nishijima, Michiharu</p> <p>2015-06-01</p> <p><i>Object</i>:To elucidate clinical aspects of <span class="hlt">ruptured</span> aneurysms, we retrospectively investigated associations between risk factors and <span class="hlt">ruptured</span> and unruptured cases during conservative management. <i>Methods</i>:Two hundred and twenty-nine patients with 291 unruptured cerebral aneurysms treated between 2000 and 2012 were analyzed.

This higher incidence is caused by the typical current demographic changes in the population and the higher level of activity and athletic motivation of the older people in our society. In this review we address the most important ligament <span class="hlt">ruptures</span> of the lower extremity in the old patient. Quadriceps tendon and Achilles tendon <span class="hlt">ruptures</span> are mostly the result of degenerative and abrasion changes. The ACL <span class="hlt">rupture</span> on the other hand occurs spontaneously after adequate trauma and without former degenerative changes especially in highly active patients. For a differentiated treatment of the older patient with tendon <span class="hlt">ruptures</span>, secondary diseases, an increased risk and complication profile and a potentially decreased compliance during rehabilitation must be taken into consideration before indicating operative or conservative therapy. There are no strict age-related limitations for indication of an operative treatment of tendon <span class="hlt">ruptures</span> in the older patient. In this patient group a differentiated treatment decision is recommended.

For strong <span class="hlt">shocks</span>, the sonic Mach number scales out, so two parameters determine the evolution: the ratio of cloud to intercloud density, and the Alfven Mach number. We focus on the case with initial field parallel to the <span class="hlt">shock</span> velocity, though we also present one model with field perpendicular to the velocity. Even with 100 zones per cloud radius, we find that the magnetic field structure converges only at early times. However, we can draw three conclusions from our work. First, our results suggest that the inclusion of a field in equipartition with the preshock medium can prevent the complete destruction of the cloud found in the field-free case recently considered by Klein, McKee, & Colella. Second, the interaction of the <span class="hlt">shock</span> with the cloud can amplify the magnetic field in some regions up to equipartition with the post-<span class="hlt">shock</span> thermal pressure. In the parallel-field case, the <span class="hlt">shock</span> preferentially amplifies the parallel component of the field, creating a 'flux rope,' a linear structure of concentrated magnetic field.

As mechanical forces may impact lesion stability, finite element studies have been conducted on models of diseased vessels to elucidate the effects of lesion characteristics on the stresses within plaque materials. It is hoped that patient-specific biomechanical analyses may serve clinically to assess the <span class="hlt">rupture</span> potential for any particular lesion, allowing better stratification of patients into the most appropriate treatments. Due to a sparsity of in vivo plaque <span class="hlt">rupture</span> data, the relationship between various mechanical descriptors such as stresses or strains and <span class="hlt">rupture</span> vulnerability is incompletely known, and the patient-specific utility of biomechanical analyses is unclear. In this article, we present a comparison between carotid atheroma <span class="hlt">rupture</span> observed in vivo and the plaque stress distribution from fluid–structure interaction analysis based on pre-<span class="hlt">rupture</span> medical imaging. The effects of image resolution are explored and the calculated stress fields are shown to vary by as much as 50% with sub-pixel geometric uncertainty. Within these bounds, we find a region of pronounced elevation in stress within the fibrous plaque layer of the lesion with a location and extent corresponding to that of the observed site of plaque <span class="hlt">rupture</span>.

The literature is reviewed in regard to the fetal biophysical profile, the effect of premature <span class="hlt">rupture</span> of membranes (PROM), the usefulness of individual biophysical component in predicting intraamniotic infection (amniotic fluid volume, non-stress testing), the use of the fetal biophysical profile in improving pregnancy outcome, the relationships among umbilical artery velocimetry, fetal biophysical profile and intraamniotic infection and the mechanisms by which infection diminishes fetal biophysical activities in PROM. After reviewing our own as well as the published experience with the use of fetal biophysical assessment in patients with PROM, the following conclusions are suggested: a) most studies have shown strong correlation between abnormal biophysical assessment and infection outcome (maternal and/or neonatal infection) as well as intraamniotic infection, if there is frequent (i.e. daily) testing; and b) fetal biophysical tests (profiles, NSTs, amniotic fluid volume determinations) are quite reliable in predicting the well fetus who can safely remain in-utero and also the fetus who is at high risk for developing neonatal sepsis. A protocol for management of preterm PROM will be outlined based upon frequent (daily) fetal biophysical assessment. Although there are no controlled randomized trials to support that pregnancy outcome is improved by the use of frequent biophysical assessment, non-randomized studies as well as studies with historic controls suggest that the use of frequent biophysical assessment is beneficial in managing patients with PROM.

R.</p> <p>2014-12-01</p> <p>The South Napa earthquake produced the largest and most extensive coseismic surface <span class="hlt">rupture</span> of any documented California earthquake of similar magnitude. More than 14 km of complex surface faulting, extending from the Napa River at Cuttings Wharf northward beyond the north boundary of Alston Park in the city of Napa, occurred on two principal sub-parallel N-NW trending fault strands. Other minor sub-parallel <span class="hlt">rupture</span> zones (?1.5 km in length with ~1-3 cm displacements) were identified near the principal strands. The surface <span class="hlt">rupture</span> lies primarily NW of the epicenter and W of most of the mapped traces of the West Napa fault zone, but <span class="hlt">rupture</span> was locally coincident with portions of some mapped late Quaternary and older fault traces. Geomorphic expressions of prior faulting are observed intermittently along the <span class="hlt">main</span> traces. Surface displacements are predominantly right lateral and typically expressed as discontinuous en echelonleft-stepping fractures within zones that range from <1 m, to tens of meters in width. The largest lateral offsets occurred on the western principal strand; coseismic slip was minimal near the epicenter but increased to 40-45 cm ~10 km to the NW. Farther north, in the Browns Valley area, offsets of 10-20 cm across roads, pipelines, and residential structures produced significant damage. The ~7 km-long eastern strand had coseismic dextral offsets of 2-8 cm. Its southern end lies 7.5 km NW of the epicenter and 1.1 km E of the western strand, while its northern end approaches the western strand where the two appear to merge a few hundred meters south of Alston Park. Afterslip has been documented along the western strand but was not observed on the eastern strand. It was most rapid in the middle third of the western strand, increasing initial slip by ?20 cm one day after the mainshock. Repeated measurements suggest total slip may reach ~40 cm along half of the western strand. The complex character and locations of surface <span class="hlt">rupture</span> produced by this event have significant implications for current approaches to fault hazard mapping in California.

These <span class="hlt">shock</span> polar solutions provide a simple means of visualizing the complex nonlinear nature of <span class="hlt">shock</span> wave interactions. This methodology, however, is not limited to the treatment of an ideal gas. While the framework can be extended to a completely general equation of state, the emphasis here will be on the description of oblique <span class="hlt">shocks</span> in a hydrodynamic Mie-Gruneisen solid. The oblique <span class="hlt">shock</span> relations for the principal Hugoniot, second <span class="hlt">shock</span> Hugoniot, and release isentrope are presented and used to solve two different <span class="hlt">shock</span> reflection problems.

Methods 119 IAs (38 <span class="hlt">ruptured</span>, 81 unruptured) were analyzed from 3D angiographic images and CFD. Six morphologic and seven hemodynamic parameters were evaluated for significance with respect to <span class="hlt">rupture</span>. Receiver-operating characteristic (ROC) analysis identified area under the curve (AUC) and optimal thresholds separating <span class="hlt">ruptured</span> from unruptured aneurysms for each parameter. Significant parameters were examined by multivariate logistic regression analysis in 3 predictive models—morphology only, hemodynamics only, and combined—to identify independent discriminants, and the AUC-ROC of the predicted probability of <span class="hlt">rupture</span> status was compared among these models. Results Morphologic parameters (Size Ratio [SR], Undulation Index, Ellipticity Index, and Nonsphericity Index) and hemodynamic parameters (Average Wall Shear Stress [WSS], Maximum intra-aneurysmal WSS, Low WSS Area, Average Oscillatory Shear Index [OSI], Number of Vortices, and Relative Resident Time) achieved statistical significance (p<0.01). Multivariate logistic regression analysis demonstrated SR to be the only independently significant factor in the morphology model (AUC=0.83, 95% confidence interval [CI] 0.75–0.91), whereas WSS and OSI were the only independently significant variables in the hemodynamics model (AUC=0.85, 95% CI 0.78–0.93). The combined model retained all three variables, SR, WSS, and OSI (AUC=0.89, 95% CI 0.82–0.96). Conclusion All three models—morphological (based on SR), hemodynamic (based on WSS and OSI), and combined—discriminate IA <span class="hlt">rupture</span> status with high AUC values. Hemodynamics is as important as morphology in discriminating aneurysm <span class="hlt">rupture</span> status.

Hundreds of underwater <span class="hlt">shock</span> waves are generated outside the patient's body and focused on the kidney stone. Stones fracture <span class="hlt">mainly</span> due to spalling, cavitation and layer separation.

Bubbles expand, stabilize and finally collapse violently, creating stone-damaging secondary <span class="hlt">shock</span> waves and microjets. Bubble collapse can be intensified by sending a second <span class="hlt">shock</span> wave a few hundred microseconds after the first. A novel method of generating two piezoelectrically generated <span class="hlt">shock</span> waves with an adjustable time delay between 50 and 950 µs is described and tested. The objective is to enhance cavitation-induced damage to kidney stones during ESWL in order to reduce treatment time.

M.</p> <p>2011-12-01</p> <p>Several physical mechanisms have been proposed for generating episodic slow slip, including fault gouge dilatancy at low effective stress, a velocity-weakening/velocity-strengthening transition with increasing slip speed, a fault size that is ``just right'', and appropriate forms of heterogeneity. Each, with various degrees of tuning, appears capable of generating slip speeds, stress drops, recurrence intervals, and migration speeds that are reasonably consistent with observations. In order to distinguish between these mechanisms it will be necessary to throw more observations into the mix. As geodetic data typically lack the necessary temporal and spatial resolution, the most detailed images we have of slow slip to date are inferred from locations of the associated tectonic tremor. In addition to the well-documented along-strike migration speeds of 5-10 km/day, tremor locations have led to the recognition of ``rapid tremor reversals'', that propagate tens of kilometers back in the direction from whence the <span class="hlt">main</span> front came at roughly 10 times the speed [Houston et al., Nat. Geo., 2011], and ``tremor streaks'' that propagate tens of kilometers in the slip direction, roughly ten times faster still [Shelly et al., G-cubed, 2007; Ghosh et al., G-cubed, 2010]. The details of the time, space, and amplitude distribution of tremor behind the slow slip front may provide useful constraints on models of slow slip. If fortunate, I will report on efforts to more fully characterize tremor activity behind the propagating slow front in Cascadia. If less fortunate, I will explore some of the implications of the proposed mechanisms listed above for the behavior of slip speed behind the <span class="hlt">rupture</span> front, along the lines of Rubin [G-cubed, 2011].</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=SCIGOV-MAS&redirectUrl=http://academic.research.microsoft.com/Publication/48811042"><span id="translatedtitle">Fundamentals of collisionless <span class="hlt">shocks</span> for astrophysical application, 2.

There is, however, good evidence that, irrespective of the trigger mechanism and the progenitor's identity, GRBs involve ultra-relativistic flows. It has been suggested that such outflows develop <span class="hlt">shocks</span> due to their deceleration by the surrounding medium (external <span class="hlt">shocks</span>) and, possibly, due to variability within the flow (internal <span class="hlt">shocks</span>). Such <span class="hlt">shocks</span> are believed to act as particle accelerators and magnetic field amplifiers. In this thesis, we study the spectral properties of external and internal <span class="hlt">shocks</span>. We employ an extensive parameterization of the uncertain physical processes (electron injection and acceleration, magnetic field amplification) in the <span class="hlt">shocks</span> and calculate the time averaged spectra that result from synchrotron emission and its inverse Compton scattered counterpart. Overall, the resulting spectra share the defining properties of the observed ones: they are non-thermal, they show a break (whose value is not fixed by the model), and spectral slopes in the range that was revealed by fitting BATSE spectra. The hardness-duration anti-correlation and the brightness-hardness correlation are properties inherent to the model spectra (both in external and internal <span class="hlt">shocks</span>). The spectra are, in general, very broad and counterparts in higher and lower frequencies are predicted. Behaviors such as X-ray deficiency and occasional X-ray excess are common. We discuss the broad-band properties of the spectra and the spectral differences between internal and external <span class="hlt">shocks</span> bursts. We also examine the spectral properties arising from the deceleration of an unsteady wind that results in hard and delayed emission from external <span class="hlt">shocks</span> following the <span class="hlt">main</span> burst from internal ones. We conduct a parameter search in order to identify the environments external <span class="hlt">shock</span> bursts take place in, as well as the radiative properties of the <span class="hlt">shocks</span>. Internal <span class="hlt">shocks</span> are semi-relativistic (v?0.6c), but one of the external <span class="hlt">shocks</span> is ultra-relativistic (v ~ > 0.99995c). The properties of very relativistic <span class="hlt">shocks</span> are poorly understood. Our parameter space covers a wide range of values intended to describe these <span class="hlt">shocks</span>' capabilities as these are suggested by the spectral properties of GRBs.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=PUBMED&redirectUrl=http://www.ncbi.nlm.nih.gov/pubmed/19329920"><span id="translatedtitle">An unusual late complication after SFA stenting: the artery <span class="hlt">rupture</span>.</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Chisci, E; De Donato, G; Setacci, F; Raucci, A; Giubbolini, M; Setacci, C</p> <p>2009-04-01</p> <p>Peripheral artery <span class="hlt">rupture</span> as a late complication of an endovascular stenting, due to the protrusion of a stent, has never been described in the literature in thigh arteries. Here we describe two anecdotic cases of artery <span class="hlt">rupture</span> after superficial femoral artery (SFA) stenting. In both cases the endovascular procedure was performed as a reintervention at 2 and 27 months after a failed surgical or hybrid procedure for limb revascularization. The stent had been delivered in the first part of the SFA and the <span class="hlt">rupture</span> occurred at the junction between the common femoral artery and SFA, which is one of the most flexible parts of the femoral artery. The cause of <span class="hlt">rupture</span> was probably caused by an ulcer of the stent against the artery wall concomitant with a status of local or systemic infection. A huge pseudoaneurysm developed in both cases. The massive bleeding was stopped by an emergency surgical bypass, with the removal of the stented artery. These two cases show the possibility of SFA <span class="hlt">rupture</span> after stenting. Previous surgical treatment, the site of stenting (first part of the SFA) and an active infection could predispose patients to this life-threatening complication.

It has been well documented to occur as a complication of primary or secondary hepatic malignancy. Similarly, there are 28 cases of <span class="hlt">ruptured</span> haemangiomata described in the world literature. It is also well described in severe pregnancy-induced hypertension and is said to carry a mortality of 18% for patients treated by packing and drainage of the haematoma and 75% for patients treated with liver resection. Two female patients aged 60 and 61 presented to our accident and emergency department. One had a history of hypertension only and the other a history of a bleeding diathesis from the lupus anticoagulant. Both presented with hypotension and abdominal pain and both were diagnosed by abdominal CT scan. One was treated with hepatic artery ligation and tamponade and the other with liver resection and correction of the coagulopathy. Neither had any evidence of a <span class="hlt">ruptured</span> haemangioma or tumour at laparotomy or on histological examination, and both are alive and well. The conclusions to be drawn from this review and our own recent experience is that the treatment of choice for <span class="hlt">ruptured</span> haemangiomata is liver resection and, for <span class="hlt">rupture</span> during pregnancy, is tamponade with packs and evacuation of the haematoma. Hepatic arteriography and embolisation, if possible, is a useful adjunct. Correction ofany coagulopathy is essential. We can only speculate that the aetiology in our patients was uncontrolled hypertension in one and coagulopathy in the other.

Patterns of surface deformation were investigated in analogue experiments using cohesive and non-cohesive granular materials above a vertical, planar, strike-slip basement fault. Surface deformation during the experiments was monitored by 3D PIV (Particle Imaging Velocimetry) and 2D time-lapse photography. Analysis of the experiments focused on fault zone morphology and development, as well as comparisons between the models and surface deformation observed along the Greendale Fault that resulted from the 2010 Darfield earthquake, New Zealand. Complex surface <span class="hlt">rupture</span> patterns with similar characteristics to the Greendale Fault (en echelon fractures, Riedel shears, pop-up structures, etc.) were generated by a simple fault plane of uniform dip, slip, and frictional properties. The <span class="hlt">main</span> controls on surface <span class="hlt">rupture</span> morphology were found to be the properties and thickness of the overburden, the nature of the material surface, and the overall displacement of the underlying fault. Mapping the evolution of fracture patterns with progressive shear strain reveals that Riedel shears, striking 0-30° from the underlying basement fault, are more frequently reactivated during multiple displacement (earthquake) cycles, and are thus most likely to provide reliable paleoseismic records. This information will assist in the identification of suitable locations for paleoseismic trenches and in the interpretation of trench records from the Greendale Fault and other active, strike-slip faults in analogous geologic settings. The results also highlight the tendency of trenching studies of faults of this type to underestimate the number of and displacements on previous <span class="hlt">ruptures</span>, which potentially leads to an underestimate of the magnitude potential and recurrence interval of paleoearthquakes.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=DOE-PATENT-XML&redirectUrl=http://www.osti.gov/doepatents/biblio/868794"><span id="translatedtitle"><span class="hlt">Shock</span> destruction armor system</span></a></p> <p><a target="_blank" href="http://www.osti.gov/doepatents">DOEpatents</a></p> <p>Froeschner, Kenneth E.

People travel for many and varied reasons, from the business person on an overseas assignment to backpackers seeking new and exotic destinations. Others may take up residence in different regions, states or countries for family, business or political reasons. Other people are fleeing religious or political persecution. Wherever they go and for whatever reason they go, people take their culture with them. Culture, like language, is acquired innately in early childhood and is then reinforced through formal and complex informal social education into adulthood. Culture provides a framework for interpersonal and social interactions. Therefore, the contact with a new culture is often not the exciting or pleasurable experience anticipated. When immersed in a different culture, people no longer know how to act when faced with disparate value systems. Contact with the unfamiliar culture can lead to anxiety, stress, mental illness and, in extreme cases, physical illness and suicide. "Culture <span class="hlt">shock</span>" is a term coined by the anthropologist Oberg. It is the <span class="hlt">shock</span> of the new. It implies that the experience of the new culture is an unpleasant surprise or <span class="hlt">shock</span>, partly because it is unexpected and partly because it can lead to a negative evaluation of one's own culture. It is also known as cross-cultural adjustment, being that period of anxiety and confusion experienced when entering a new culture. It affects people intellectually, emotionally, behaviorally and physically and is characterized by symptoms of psychological distress. Culture <span class="hlt">shock</span> affects both adults and children. In travelers or workers who have prolonged sojourns in foreign countries, culture <span class="hlt">shock</span> may occur not only as they enter the new culture, but also may occur on their return to their original culture. Children may also experience readjustment problems after returning from leading sheltered lives in expatriate compounds. This readjustment back to their own culture after a period of time abroad has been termed "reverse culture <span class="hlt">shock</span>, a condition which has been studied in both corporate managers and Peace Corps volunteers. With culture <span class="hlt">shock</span> and many other processes of psychological adjustment, people tend to suffer alone, thinking that they are the only ones not coping well with their new circumstance. The objective of this paper was to bring the phenomenon of culture <span class="hlt">shock</span> to the awareness of travel health advisors, who can in turn advise travelers, especially longer term travelers, about having realistic expectations of their travel and life in new cultures.

Theoretical computation of far-field waveforms with this model shows that a slow initial phase preceding the <span class="hlt">main</span> P phase expected from a classical source model is radiated in the accelerating stage from the slow dynamic <span class="hlt">rupture</span> growth to the high-speed <span class="hlt">rupture</span> propagation. On the assumption that the physical law governing <span class="hlt">rupture</span> processes in natural earthquakes is essentially the same as that in stick-slip events, we scaled the theoretical source model explaining the stick-slip experiments to the case of natural earthquakes so that the scaled source model explains the observed average stress drop, the critical nucleation-zone size, and the duration of the slow initial phase well. The physical parameters prescribing the source model are the weak-zone size L , the critical weakening displacement Dc , the breakdown strength drop ?b , and the rigidity ? of the surrounding elastic medium. In scaling these parameters, we held a non-dimensional controlling parameter ?' = (?Dc )/(?b L ) in numerical simulation constant. From the results of scaling we found the following fundamental relations between the source parameters: (1) the critical weakening displacement Dc is in proportion to the weak-zone size L , but (2) the breakdown strength drop ?b is independent of L .</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=NASAADS&redirectUrl=http://adsabs.harvard.edu/abs/2007APS..SHK.V6001S"><span id="translatedtitle">Violent Reactions from Non-<span class="hlt">Shock</span> Stimuli</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Sandusky, Harold</p> <p>2007-06-01</p> <p>Most reactions are thermally initiated, whether from direct heating or dissipation of energy from mechanical, <span class="hlt">shock</span>, or electrical stimuli. For other than prompt <span class="hlt">shock</span> initiation, the reaction must be able to spread through porosity or over large surface area to become more violent than just <span class="hlt">rupturing</span> any confinement. While burning rates are important, high-strain mechanical properties are nearly so, either by reducing existing porosity or generating additional surface area through fracture. The first example is deflagration-to-detonation transition (DDT) in porous beds. During the early stages, weak compressive waves ahead of the convective ignition front will reduce porosity, thereby restricting the spread of combustion and the pressure buildup. If, however, pressure increases faster than can be relieved by loss of confinement, coalescing compressive waves can initiate reaction at hot spots from rapid pore collapse. This compressive reaction can drive a shockwave that transits to detonation, the most violent reaction in any scenario. It has been shown that reaction violence is reduced in DDT experiments if the binder is softened, either by raising the initial temperature or adding a solvent. An example of the role of mechanical properties in enhancing reaction violence through fracturing occurs when cavities in projectile fills collapse during acceleration in the gun barrel, which is referred to as setback. Explosives with soft rubber binders will deform and undergo mild reaction from shear heating within the explosive and adiabatic compression of any gas in the cavity. Stiff explosives are similarly ignited, but also fracture and generate additional surface area for a violent event. The last example to be considered is slow cook-off, where thermal damage can increase burning rate as well as provide porosity to enhance the pressure buildup. As reaction spreads from the zone of thermal run-away, an explosive binder that resists breakup will limit the violence.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=NASAADS&redirectUrl=http://adsabs.harvard.edu/abs/2014EGUGA..1613669S"><span id="translatedtitle">Contemporary surface <span class="hlt">ruptures</span> in the zone of the Baikal-Mondy fault (Baikal rift system): dynamics of formation and origin</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Sankov, Vladimir; Sankov, Aleksei; Lebedeva, Marina; Ashurkov, Sergey; Parfeevets, Anna</p> <p>2014-05-01</p> <p>Sublatitudinal Baikal-Mondy (Tunka) left-lateral strike-slip fault accommodates North Mongolia submeridional rift basins opening (Darkhad and Khubsugul). It is the connecting link between the central and south-western parts of the Baikal rift system. We investigated the present-day activity of faulting on southern border of Mondy basin, which is due to their position at the junction of east-west trending active faults of the Baikal-Mondy fault system with submeridional structures of Khubsugul basin. The investigated area is characterized by high seismic activity. The epicenter of one of the strongest Mondy earthquake 1950 (Mw = 7.0) is located within the Mondy basin. Reconstruction of Late Cenozoic tectonic stress field shows a predominance of strike-slip deformation regime with NW-SE direction of the minimum compression axis and NE-SW direction of the maximum compression axis, which correlates with the present-day stress field derived from the data on earthquake focal mechanisms. On the top of the southern shoulder of Mondy basin a series of extended NE trending surface <span class="hlt">ruptures</span> that cut the crust of weathering and bedrock across the local watershed were discovered. The <span class="hlt">rupture</span> length reaches 180 m, width <span class="hlt">ruptures</span> bedrock reaches 0.6 m. In the bedrock tectonic microfractures of NW and NE directions are dominated, but the NW trending surface <span class="hlt">ruptures</span> are not observed. In the area of contemporary <span class="hlt">ruptures</span> the geodetic measurements were carried out in the period 2009-2013. The results of processing the measurement data on the local testing ground showed that most divergent baselines undergoes extension with maximum values reaching 30 mm/year. The block experienced elongation in all directions, but the morphology of <span class="hlt">ruptures</span> suggests that the <span class="hlt">main</span> direction of stretching is NW-SE. The intensity of cracks opening decreases markedly with time. According to eyewitnesses known that active crack opening at about 100 mm/year started 4 years before Kultuk earthquake (27.08.2008, Mw = 6.3), the epicenter of which was located near the southern tip of the Baikal basin. The existence of centimeter level deformations is confirmed using of differential SAR interferometry method. A pair of images taken with an interval of 2 years highlighted the linear zone of active deformation in the centimeter level. The length of the structure is about 4 kilometers. The offset along the Line-of-Sight (LOS) direction is from 18 to 42 mm, which corresponds to the vertical displacement of 22 to 50 mm, or a horizontal displacement of 32 to 74 mm (Lebedeva et al., 2013). Along with the described <span class="hlt">ruptures</span> we discovered normal faults with an amplitude greater than 2 m, which can be traced along the submeridional local watershed. The length of the normal faults reaches 800 m. The morphology and position of these faults can be attributed to their sackung structures. We conclude that the detected current surface <span class="hlt">ruptures</span> have complex origins and develop under the influence of endogenous (tectonic) and exogenous forces. They founded along NE trending ancient tectonic structures within wide strike-slip zone and <span class="hlt">main</span> direction of opening corresponds to the direction of extension of paleo- and present-day stress field. According to the dynamics of <span class="hlt">ruptures</span> opening, the <span class="hlt">main</span> phase of their formation is connected with stage of Kultuk earthquake preparation.

It is found that two head-on <span class="hlt">shocks</span> diminish both in strength after collisions and a tangential discontinuity forms between them. The property of the discontinuity depends on the relative strength of the two <span class="hlt">shocks</span>. No discontinuity occurs if the <span class="hlt">shocks</span> are equal in strength. The emerging of two <span class="hlt">shocks</span> propagating in the same direction results in a strong <span class="hlt">shock</span> followed by a tangential discontinuity and a reverse wave. The reverse wave is a rarefaction wave if one or both of the <span class="hlt">shocks</span> are strong. If the <span class="hlt">shocks</span> are both weak, a critical adiabatic index (CAI) exists. The reverse wave is a rarefaction wave if the wavelength is less than the CAI and a <span class="hlt">shock</span> exists if the wavelength is greater than the CAI.

Michael; Izmirly, Peter M.; Becske, Tibor; Huang, Paul P.</p> <p>2015-01-01</p> <p>Background: Subarachnoid hemorrhage (SAH) due to intracranial aneurysm <span class="hlt">rupture</span> is a major neurosurgical emergency associated with significant morbidity and mortality. Rapid aneurysm growth is associated with <span class="hlt">rupture</span>. Systemic lupus erythematosus (SLE) is a multi-system autoimmune disorder whose complications can include cerebral vasculitis and vasculopathy. Intracranial aneurysms are not known to occur more frequently in SLE patients than the general population; however, aneurysm growth rates have not been studied in SLE. Case Description: We present a 43-year-old female with SLE on prednisone, hydroxychloroquine, and azathioprine with moderate disease activity who presented with severe, acute-onset headache and was found to have Hunt and Hess grade II SAH due to <span class="hlt">rupture</span> of an 8 mm saccular anterior communicating artery (ACoA) aneurysm. The patient developed severe vasospasm, re-<span class="hlt">ruptured</span>, and was taken for angiography and embolization, which was challenging due to a high degree of vasospasm and arterial stenosis. Review of imaging from less than 2 years prior demonstrated a normal ACoA complex without evidence of an aneurysm. Conclusion: We review the literature and discuss the risk factors and pathophysiology of rapid aneurysm growth and <span class="hlt">rupture</span>, as well as the pathologic vascular changes associated with SLE. Although SLE patients do not develop intracranial aneurysm at an increased rate, these changes may predispose them to higher incidence of growth and <span class="hlt">rupture</span>. This possibility-coupled with increased morbidity and mortality of SAH in SLE-suggests that SAH should be considered in SLE patients presenting with headache, and advocates for more aggressive treatment of SLE patients with unruptured aneurysms.

M.</p> <p>2011-12-01</p> <p>Natural faults during their evolution stages manifest varying degrees of geometric complexities over a broad range of scales spanning from larger-scale features such as branching and segmentation to smaller-scale features such as topographic variations on the slip surface. At a microscopic scale, surface roughness affects the frictional properties through its role in the distribution and evolution of contact areas of the sliding surface. At a larger scale, the geometric irregularities of the fault affects the inter-seismic and post-seismic static stress distribution that is responsible for earthquake nucleation. Our study, however, focuses on the fundamental role that surface roughness plays in the dynamic processes of earthquake <span class="hlt">rupture</span> propagation and resultant ground motion using numerical simulations of 3D dynamic <span class="hlt">rupture</span>. As have been shown in several previous 2D numerical studies, dynamic <span class="hlt">ruptures</span> propagating along rough fault surface can excite high-frequency radiation as they accelerate and decelerate from interaction with geometric irregularities. Also perturbation of local dynamic stress due to roughness contributes to the heterogeneous distributions of slip rate and slip over the entire fault. With the goal of producing more realistic physics-based dynamic ground motion, we perform 3D numerical simulations of dynamic <span class="hlt">rupture</span> along faults with self-similar roughness distribution of wavelength scales spanning three orders of magnitude (10^2 -10^5 m). We examine the influence of fault roughness characteristics (shortest wavelength and amplitude-to-wavelength ratio) on the <span class="hlt">rupture</span> behavior, the resultant ground motion pattern and the final slip pattern. The fault is governed by a rate-and-state friction with strongly velocity-weakening feature and the inelastic yielding of off-fault bulk material is subject to Drucker-Prager viscoplasticity. Initial investigations clearly indicate that the amount of high-frequency radiation generated and <span class="hlt">rupture</span> properties are heavily influenced by the roughness properties. Detailed analyses of our simulation results will be presented at the conference.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=PMC&redirectUrl=http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=3070915"><span id="translatedtitle">Association of Hemodynamic Characteristics and Cerebral Aneurysm <span class="hlt">Rupture</span></span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pmc">PubMed Central</a></p> <p>Cebral, Juan R.; Mut, Fernando; Weir, Jane; Putman, Christopher M.</p> <p>2011-01-01</p> <p>Background and purpose Hemodynamic factors are thought to play an important role in the initiation, growth and <span class="hlt">rupture</span> of cerebral aneurysms. This report describes a study of the associations between qualitative intra-aneurysmal hemodynamics and the <span class="hlt">rupture</span> of cerebral aneurysms. Methods 210 consecutive aneurysms were analyzed using patient-specific CFD simulations under pulsatile flow conditions. The aneurysms were classified into categories depending on the complexity and stability of the flow pattern, size of the impingement region, and inflow concentration by two blinded observers. A statistical analysis was then performed with respect to history of previous <span class="hlt">rupture</span>. Inter-observer variability analysis was performed. Results <span class="hlt">Ruptured</span> aneurysms were more likely to have complex flow patterns (83%, p<0.001), stable flow patterns (75%, p=0.0018), 66% concentrated inflow (66%, p=<0.0001), and small impingement regions (76%, p=0.0006) compared to unruptured aneurysms. Inter-observer variability analyses indicate that all the classifications performed are in very good agreement, i.e. well within the 95% confidence interval. Conclusions A qualitative hemodynamic analysis of cerebral aneurysms using image based patient-specific geometries has shown that concentrated inflow jets, small impingement regions, complex flow patterns, and unstable flow patterns are correlated with a clinical history of prior aneurysm <span class="hlt">rupture</span>. These qualitative measures provide a starting point for more sophisticated quantitative analysis aimed at assigning aneurysm risk of future <span class="hlt">rupture</span>. These analyses highlight the potential for CFD to play an important role in the clinical determination of aneurysm risks.

B.; Fukuyama, E.; Madariaga, R.</p> <p></p> <p>We have developed a hybrid method for flexible and efficient modeling of the entire earthquake process, from dynamic <span class="hlt">rupture</span> propagation to the radiation in a hetero- geneous three-dimensional medium. The dynamic <span class="hlt">rupture</span> propagation is computed using the boundary integral equation method (BIEM), and the wave propagation out- side the fault is carried out by a fourth-order finite-difference method (FDM). Thus, our method combines the flexibility of the BIEM to compute spontaneous <span class="hlt">rupture</span> propagation on non-planar or multi-segmented fault geometries using a wide range of friction laws with the efficiency of the FDM to compute wave propagation in arbitrar- ily heterogeneous crustal models. The method has several important applications. The effects of fault segmentation and curvature on dynamic <span class="hlt">rupture</span> propagation and its dynamic radiation can be analyzed in detail. The presence of any significant signature in ground motion patterns from dynamic effects for <span class="hlt">rupture</span> propagation on non-planar fault geometries can be used to develop guidelines to improve future kinematic (prescribed) simulations. In addition, the statistics of recurrent <span class="hlt">ruptures</span> on multiple, arbitrarily-shaped fault systems can be computed and used to increase our knowledge of earthquake occurrence. Here, we present details of the implementation of the hybrid method and the interface between the BIEM and FDM. We also show preliminary results for hybrid simulations of the 1992 M7.3 Landers, California, and the 1999 M7.4 Izmit, Turkey, earthquakes. Both earthquakes were associated with complex fault geometry on vertical fault sys- tem in the simulations. For the two events, we compute the ground motion for different fault geometry models and compare synthetic seismograms to strong motion data.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=ERIC&redirectUrl=http://eric.ed.gov/?q=maine&pg=6&id=EJ783363"><span id="translatedtitle">The <span class="hlt">Maine</span> Event</span></a></p> <p><a target="_blank" href="http://www.eric.ed.gov/ERICWebPortal/search/extended.jsp?_pageLabel=advanced">ERIC Educational Resources Information Center</a></p> <p>McHale, Tom</p> <p>2007-01-01</p> <p>In this article, the author describes the successful laptop program employed at Mt.

The female population specifically has an expanded differential diagnosis that should be considered when these patients present with hemodynamic collapse. While the most common causes of hypotension in pregnant patients are dehydration, <span class="hlt">ruptured</span> ectopic pregnancy, and placental and uterine abnormalities, less common nonobstetrical etiologies such as hepatic <span class="hlt">rupture</span> and <span class="hlt">ruptured</span> abdominal and visceral artery aneurysms should also be considered. Splenic artery aneurysms are associated with high rates of mortality and in cases of pregnancy, maternal and fetal mortality.

A basic assumption of this model is that a local slip weakening distance (or fracture energy) at a point is proportional to the size of the minimum asperity which includes that point. Since typical topography of fault surface obeys self-affine fractal statistics, we assumed that the asperity distribution is also represented by a power law. For simplicity we prepared seven different sizes of circular patches as discretized representation of asperities. When the patch radius increases by two, the number of patches decreases by four, where the fractal dimension is 2. The whole model space is a fault plane of 4096x4096 square grids, on which the circular patches are distributed randomly. This space is represented by four 64x64 subspaces on different scales and each subspace is connected to the subspaces on the larger and/or smaller scales by renormalization. The assumed values of initial, yield, and residual stresses are homogeneous across the fault plane. We begin each dynamic <span class="hlt">rupture</span> simulation with breaking one of the patches of the minimum level. In most cases, the <span class="hlt">rupture</span> stops immediately after the initiation. Sometimes, the <span class="hlt">rupture</span> coalesces with adjacent patches, propagates into a patch of next level. Frequency-size distribution of these events is approximated by a power law, which is explained by the probability of interaction between asperities. The probability of triggering of dense patch distribution is high and resultant slope of the power law is less steep. Whole <span class="hlt">rupture</span> process is spontaneous based on exact elasto-dynamics and slip-weakening law except for the nucleation in the minimum level. Thus we observed very heterogeneous process during the <span class="hlt">rupture</span>: <span class="hlt">Rupture</span> directivity, <span class="hlt">rupture</span> front shape, slip distribution, and moment release functions. Some moment rate functions increase irregularly, which resemble to so-called initial phases observed in real seismic waves.

E.</p> <p>2014-12-01</p> <p>Rapid documentation (<1 day) of co-seismic surface <span class="hlt">rupture</span> location and slip is essential for scientific and emergency response. We demonstrate how social media (text messaging and Twitter) and the emerging 3D data collection technique known as Structure from Motion (SfM), used in conjunction with traditional field reconnaissance, enabled us to rapidly locate and document surface <span class="hlt">ruptures</span> from the Mw 6.0 South Napa earthquake. On the morning of the event, our field team used information available on social media to identify locations with potential surface <span class="hlt">rupture</span>. Preliminary observations of surface <span class="hlt">rupture</span> (measurements and geo-tagged photographs) were texted to the office-based team member who created digital maps of the <span class="hlt">rupture</span> trace and shared them online via Twitter in near-real time. We documented many ephemeral features (such as offset roads, curbs, and driveways) along the <span class="hlt">rupture</span> trace within 12 hours of the event, before these features were destroyed by road and infrastructure repair. We were able to return to most sites again within several days, allowing us to document continuing slip and create time-series datasets of offset features. After the collection and re-collection of data at selected sites, we made detailed measurements remotely using 3D models constructed with SfM. The ability to quantitatively project features into the fault plane using these models allows for accurate measurements of small features often difficult to observe and quantify in the field. Traditionally, even preliminary maps of <span class="hlt">rupture</span> extent and offset magnitudes are not available for several days after an event because office-based processing and compilation is required. Because we were able to compile our data in real time, we distributed our results while they were still valuable for ongoing scientific response. Our work helped other science teams efficiently target fieldwork and instrument deployment; for example, one geodetic survey team used our surface <span class="hlt">rupture</span> map to adjust their field deployment plans in an effort to capture rapidly-decaying postseismic movement. With social media and rapid, inexpensive data collection methods like SfM in mind, scientific response to future events has the potential to be more efficient and coordinated than ever before.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=NASAADS&redirectUrl=http://adsabs.harvard.edu/abs/2004ApSS..238...47A"><span id="translatedtitle">Force spectroscopy of covalent bond <span class="hlt">rupture</span> versus protein extraction</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Afrin, Rehana; Okazaki, Susumu; Ikai, Atsushi</p> <p>2004-11-01</p> <p>Development of protein extraction and identification methods from a live cell surface using minimally invasive technology has an important implication as a possible tool to study time-dependent changes of the distribution of intrinsic membrane proteins in specific locals on the cell membrane.

This statistical energization mechanism, manifested in turbulent media, was first posited by Enrico Fermi in 1949 to explain the observed cosmic ray population, which exhibits an almost power-law distribution in rigidity. The absence of a momentum scale is a key characteristic of diffusive <span class="hlt">shock</span> acceleration, and astrophysical systems generally only impose scales at the injection (low energy) and loss (high energy) ends of the particle spectrum. The existence of structure in the cosmic ray spectrum (the "knee") at around 3000 TeV has promoted contentions that there are at least two origins for cosmic rays, a galactic one supplying those up to the knee, and perhaps an extragalactic one that can explain even the ultra-high energy cosmic rays (UHECRs) seen at 1-300 EeV. Accounting for the UHECRs with familiar astrophysical sites of acceleration has historically proven difficult due to the need to assume high magnetic fields in order to reduce the shortest diffusive acceleration timescale, the ion gyroperiod, to meaningful values. Yet active galaxies and gamma-ray bursts remain strong and interesting candidate sources for UHECRs, turning the theoretical focus to relativistic <span class="hlt">shocks</span>. This review summarizes properties of diffusive <span class="hlt">shock</span> acceleration that are salient to the issue of UHECR generation. These include spectral indices, anisotropies, acceleration efficencies and timescales, as functions of the <span class="hlt">shock</span> speed and mean field orientation, and also the degree of field turbulence.

We have investigated the effects of different potential examples of slip distributions on the tsunami inundation hazard posed by three earthquake sources for the shore areas of the Wellington Harbour and Wellington's south coast (New Zealand): the Hikurangi subduction interface (Mw = 9.0), the Wairarapa Fault (Mw = 8.1) with a potential contribution of the Wharekauhau Thrust, and the Wellington Fault (Mw = 7.4). We find that the crustal fault sources (Wellington Fault and Wairarapa Fault) pose less of an inundation hazard than the studied events on the Hikurangi subduction interface. The Wairarapa Fault scenarios suggest that an earthquake on this fault will <span class="hlt">mainly</span> affect the Wellington south coast. A simultaneous <span class="hlt">rupture</span> of Wharekauhau Thrust would further enhance the generation of tsunami waves. Geodetic studies suggest that slip released in a large Hikurangi earthquake is potentially concentrated at the southern part of the interface and this was found to lead to increased inundation in the Hikurangi scenarios. Non-uniform slip distributions that happen to concentrate slip in the Cook Straight region have much the same effect. This study is the first we know of that attempts to understand the effects of <span class="hlt">rupture</span> complexity on tsunami generation by earthquakes on upper plate faults, in this case the Wairarapa and Wellington Faults. The results of this study help to understand the role of earthquake complexity on tsunami generation by these faults.</p> </li> </ol> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_21");'>21</a></li> <li><a href="#" onclick='return showDiv("page_22");'>22</a></li> <li class="active"><span>23</span></li> <li><a href="#" onclick='return showDiv("page_24");'>24</a></li> <li><a href="#" onclick='return showDiv("page_25");'>25</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div><!-- col-sm-12 --> </div><!-- row --> </div><!-- page_23 --> <div id="page_24" class="hiddenDiv"> <div class="row"> <div class="col-sm-12"> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_21");'>21</a></li> <li><a href="#" onclick='return showDiv("page_22");'>22</a></li> <li><a href="#" onclick='return showDiv("page_23");'>23</a></li> <li class="active"><span>24</span></li> <li><a href="#" onclick='return showDiv("page_25");'>25</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div> </div> <div class="row"> <div class="col-sm-12"> <ol class="result-class" start="461"> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=NASAADS&redirectUrl=http://adsabs.harvard.edu/abs/2015GeoRL..42.2164E"><span id="translatedtitle"><span class="hlt">Rupture</span> termination at restraining bends: The last great earthquake on the Altyn Tagh Fault</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Elliott, Austin J.; Oskin, Michael E.; Liu-Zeng, Jing; Shao, Yanxiu</p> <p>2015-04-01</p> <p>Strike-slip <span class="hlt">rupture</span> propagation falters where changes in fault strike increase Coulomb failure stress.

This strike-slip fault extends for about 35 km from north of the Hula basin to the Awali river, and shows left-lateral strike-slip displacements (manifested as offset streams) and vertical movements. Recent seismic records indicate its seismogenic potential as the source of the double <span class="hlt">shock</span> of 16 March 1956 (Ms 4.8, 5.1) earthquake. We studied the Roum fault using combined field investigations in geomorphology, structural geology, and palaeoseismology. Fresh fault scarps and pressure ridges visible along the fault trace attest to recent coseismic <span class="hlt">ruptures</span>. A palaeoseismic trench investigation exposed a complex fault zone with several <span class="hlt">rupture</span> strands and a minimum of four faulting episodes in the last ˜10,000 years, the most recent event being post 84-239 AD. According to historical records, the 1 January 1837 (Ms 7.1) earthquake, which induced severe damage in the region, is the most likely candidate. Our results assign a slip-rate of 0.86-1.05 mm/year along the Roum fault, which shows that it accommodates about 14% of the total predicted strike-slip motion within the Lebanese restraining bend, and it should be considered a potential seismogenic fault for seismic hazard estimates in Lebanon.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=SCIGOV-MAS&redirectUrl=http://academic.research.microsoft.com/Publication/32397033"><span id="translatedtitle">Multi-slice computed tomography with N1177 identifies <span class="hlt">ruptured</span> atherosclerotic plaques in rabbits</span></a></p> <p><a target="_blank" href="http://academic.research.microsoft.com/">Microsoft Academic Search </a></p> <p>Jozef Leo Van Herck; Guido R.

P.; Wesnousky, S. G.; Morelan, A. E., III</p> <p>2014-12-01</p> <p>Observations of actual ground <span class="hlt">ruptures</span> from moderate and large earthquakes show a wide range of behaviors, including fault-to-fault jumps, branching topologies, and <span class="hlt">rupture</span> traces with multi-kilometer gaps between them. Seismic hazard assessments have responded to these observations by including increasingly sophisticated scenarios of possible <span class="hlt">ruptures</span> in their earthquake rate forecasts. The largest of these to date has been the Uniform California Earthquake Forecast 3 (UCERF3), which explicitly included <span class="hlt">ruptures</span> with fault-to-fault jumps in its <span class="hlt">rupture</span> rate estimates. High-level site-specific seismic source characterizations such as for the Diablo Canyon Power Plant have also begun including complicated <span class="hlt">rupture</span> geometries. Systematic collection of observations from ground <span class="hlt">rupturing</span> earthquakes provide one way to evaluate these seismic source models. We have expanded an initial collection by Wesnousky (2008) with events post-dating that collection and events for which new information is available. New events increase the strike-slip and normal event set by 50% and reverse events by 35%. New data allow us to revise previous estimates for strike-slip <span class="hlt">rupture</span> of the probability that a step of 1 km or more in width will arrest <span class="hlt">rupture</span>. Observationally, 65% of strike-slip <span class="hlt">ruptures</span> include at least one step of 1 km or greater. The number of steps through which <span class="hlt">ruptures</span> are observed to <span class="hlt">rupture</span> through can be modeled by a geometric distribution in which steps are crossed about 59% of the time. Steps are slightly more effective at arresting <span class="hlt">rupture</span> in normal and reverse faulting cases, being crossed 56% and 50%, respectively. New events were also systematically examined for gaps in the mapped <span class="hlt">rupture</span> trace. We find gaps of 1 km or more in about half of the <span class="hlt">ruptures</span> of the new event set. These empirical data will compliment new research into <span class="hlt">rupture</span> propagation across gaps, exemplified by the 2010 El Mayor Cucapah earthquake, which included a gap measured variously at 7 or 15 km in length.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=SCIGOV-MAS&redirectUrl=http://academic.research.microsoft.com/Publication/33951848"><span id="translatedtitle">Chronic Achilles tendon <span class="hlt">rupture</span> reconstruction using a modified flexor hallucis longus transfer</span></a></p> <p><a target="_blank" href="http://academic.research.microsoft.com/">Microsoft Academic Search </a></p> <p>Julien Wegrzyn; Jean-François Luciani; Rémi Philippot; Elisabeth Brunet-Guedj; Bernard Moyen; Jean-Luc Besse</p> <p>2010-01-01</p> <p>The purpose of this study was to report the management and outcome of 11 patients presenting with chronic Achilles tendon\\u000a (AT) <span class="hlt">rupture</span> treated by a modified flexor hallucis longus (FHL) transfer.

Turbulence kinetic energy (TKE) is amplified across the <span class="hlt">shock</span> wave, but this amplification tends to saturate beyond M(sub 1) = 3.0. TKE amplification and Reynolds stress anisotropy obtained in DNS are consistent with LIA predictions.

There were 76 cases of <span class="hlt">ruptured</span> uterus and 4,770 deliveries (1.6%) during the period. Ten women died from a <span class="hlt">ruptured</span> uterus, giving a case fatality rate of 13.2%. The mean admission-assessment interval by a senior clinician was 48.4 min. The mean decision-laparotomy interval was 6.9 h. Deviations from management protocol were noted in 66 women (86.8%) and underlying reasons were classified as patient-orientated (59.2%), medical personnel (13.2%) and administrative (22.4%) problems. Among women who died, there were more administrative problems, intraoperative and total blood losses were significantly more and preoperative haematocrit was significantly less compared with survivors. The poor quality of care for <span class="hlt">ruptured</span> uterus in this centre is attributable to patients' financial limitations, which is compounded by administrative problems, particularly those regarding inefficient blood transfusion services. This study demonstrates the urgent need for implementation of a national health insurance scheme at this centre and reiterates the feasibility of employing detailed enquiry of peripartal circumstances to identify specific problems underlying major causes of maternal morbidity and mortality.

However, the day following her labor, patient complained of left iliac fossa pain. Her blood tests revealed a CRP value at 27.6 mg/L, whereas the X-rays revealed an extensive impacted fecal mass in the colon. MRI revealed that the left lower myometrial part of the uterus was depicted abrupt, with simultaneous presence of hemorrhagic stuff. The decision of laparotomy was therefore made in order to further evaluate <span class="hlt">rupture</span> of uterus and properly treat patient. And subtotal hysterectomy was performed.

Non-operative treatment gives good results, the loss of power regarding elbow flexion and supination amounts to only 8-21%. Refixation may be indicated for cosmetic reasons and offers a small but evident improvement of flexion and supination power. Deformity of the slipped muscle can be corrected effectively. Residual complaints after conservative treatment often result from associated subacromial problems. Distal <span class="hlt">ruptures</span>. <span class="hlt">Ruptures</span> of the distal tendon should be treated operatively. The loss of power after conservative treatment is evident (30-40% for flexion, >50% for supination). Extra-anatomical tenodesis to the brachialis muscle or anatomical fixation to the radial tuberosity can be applied. Flexion power and cosmesis can be addressed by both techniques. If supination strength is to be restored, the tendon has to be fixed anatomically. Preparation of the tuberosity bears the risk of heterotopic ossification or nerve damage. Mini-open techniques, using only a limited anterior approach, may decrease risks.

Because relative to the whole fault plane, the seismic power radiation area is sparse in a specific moment during a great earthquake. CS method is used to invert the <span class="hlt">rupture</span> process from teleseismic P wave data recorded by multiple seismic arrays with different azimuths and epicentral distances. Synthetic tests illustrate that, our method can suppress the artifacts caused by interference phases ( eg. PcP ) thus we can obtain a more reliable result than using the data from a single array. Moreover, the "swimming effect" in traditional back-projection method can be reduced due to the better azimuth coverage. Then the <span class="hlt">rupture</span> process of the Mw7.9 earthquake in the Aleutian Islands, occurred at June 23, 2014 20:53 UTC is inverted. The results show that the <span class="hlt">rupture</span> is along the subduction zone, which can be used to locate the primary fault plane combined with central moment tensor. In addition, where the released power concentrates in the earthquake is also given, which could help us determine which area is effected by the earthquake most heavily, thus the rescue operation can be effective. In conclusion, different from traditional beamforming method, CS can offer a high-resolution solution.</p> </li> <li> <p><a target="resultTitleLink" href="http://www.science.gov/scigov/desktop/en/ostiblue/service/link/track?type=RESULT&searchId=topic-pages&collectionCode=SCIGOV-MAS&redirectUrl=http://academic.research.microsoft.com/Publication/38329744"><span id="translatedtitle">Cognitive impairments after surgical repair of <span class="hlt">ruptured</span> and unruptured aneurysms</span></a></p> <p><a target="_blank" href="http://academic.research.microsoft.com/">Microsoft Academic Search </a></p> <p>Argye E Hillis; Nancy Anderson; Prakesh Sampath; Daniele Rigamonti</p> <p>2000-01-01</p> <p>OBJECTIVESTo determine the frequency and severity of neuropsychological impairments associated with aneurysmal subarachnoid haemorrhage, and associated with repair of intracerebral aneurysms.METHODSTwo groups of patients who underwent repair of intracerebral aneurysms were studied: patients with unruptured aneurysms (n=20) and patients with <span class="hlt">ruptured</span> aneurysms (n=27).

We intended to describe herein an endovascular technique for the simultaneous treatment of aneurysms and vasospasm. Materials and Methods A series of 11 patients undergoing simultaneous endovascular treatment of <span class="hlt">ruptured</span> aneurysms and vasospasm were reviewed. After placement of a guiding catheter within the proximal internal carotid artery for coil embolization, an infusion line of nimodipine was wired to one hub, and of a microcatheter was advanced through another hub (to select and deliver detachable coils). Nimodipine was then infused continuously during the coil embolization. Results This technique was applied to 11 <span class="hlt">ruptured</span> aneurysms accompanied by vasospasm (anterior communicating artery, 6 patients; internal carotid artery, 2 patients; posterior communicating and middle cerebral arteries, 1 patient each). Aneurysmal occlusion by coils and nimodipine-induced angioplasty were simultaneously achieved, resulting in excellent outcomes for all patients, and there were no procedure-related complications. Eight patients required repeated nimodipine infusions. Conclusion Our small series of patients suggests that the simultaneous endovascular management of <span class="hlt">ruptured</span> cerebral aneurysms and vasospasm is a viable approach in patients presenting with subarachnoid hemorrhage and severe vasospasm.

We use simple models of DNA to demonstrate that this approach naturally captures the experimentally observed dependence of the critical force on duplex length for a given observation time.

Not all induction agents have the same magnitude of increased risk of uterine <span class="hlt">rupture</span>, and there have been only a small number of randomized controlled trials of labor induction in women with previous cesarean delivery.
