The disappearance of collective flow in nucleus-nucleus collisions occurs at an incident energy (${\mathit{E}}_{\mathrm{bal}}$) where the attractive scattering dominant low energies balances repulsive high energies. We have performed first systematic study entrance-channel mass dependence and hence ${\mathit{E}}_{\mathrm{bal}}$. new data presented for C+C, Ne+Al, Ar+Sc, Kr+Nb systems show that ${\mathit{E}}_{\mathrm{bal}}$ scales as ${\mathit{A}}^{\mathrm{\ensuremath{-}}1/3}$ A is combined...
<h3>BACKGROUND AND PURPOSE:</h3> BBA is a rare type of intracranial aneurysm that difficult to treat both surgically and endovascularly often associated with high degree morbidity/mortality. The aim this study was present clinical angiographic results, as well antiplatelet/anticoagulation regimens, endovascular treatment by using predominantly stent-assisted coil embolization. <h3>MATERIALS METHODS:</h3> Thirteen patients (men/women, 6/7; mean age, 49.3 years) ruptured BBAs were included...
Object The calcium antagonist nimodipine has been shown to reduce the incidence of ischemic complications following aneurysmal subarachnoid hemorrhage (SAH). Although most randomized studies have focused on effect peroral administration nimodipine, intravenous infusion is an alternative and preferred mode treatment in many centers. It unknown whether route any importance for clinical efficacy drug. Methods One hundred six patients with acute SAH were receive either or treatment. monitored at...
Background and Purpose Embolization is the first-line treatment for dural arteriovenous fistulas (dAVF). The precipitating hydrophobic injectable liquid (PHIL) embolic agent a non-adhesive copolymer with specific features endovascular behavior. This study assessed its safety efficacy in prospective real-life cohort. Methods PHIL-dAVF was single-arm open-label observational multicenter conducted between October 2017 November 2019 14 European centers. Patients single intracranial dAVF intended...
We have measured two-fragment reduced-velocity correlation functions of the intermediate mass fragments (IMF: 3\ensuremath{\le}Z\ensuremath{\le}7) produced in multifragment final states for Kr+Nb system (E/A=35, 45, 55, 65, and 75 MeV). From we extract mean IMF emission lifetimes (\ensuremath{\tau}) which are observed to decrease from \ensuremath{\tau}\ensuremath{\approxeq}400 fm/c at E/A=35 MeV \ensuremath{\tau}\ensuremath{\approxeq}125 E/A=55 MeV. For beam energies excess MeV, no further...
<h3>BACKGROUND AND PURPOSE:</h3> The introduction of liquid embolic agents has revolutionized endovascular approach to cranial vascular malformations. aim the study was retrospectively assess efficacy and safety Precipitating Hydrophobic Injectable Liquid (PHIL), a new nonadhesive agent, in treatment patients with dural arteriovenous fistulas. primary end point rate complete occlusion Secondary points included incidence adverse events clinical status at 3-month follow-up. <h3>MATERIALS...
We present Z distributions for fragments with 1\ensuremath{\le}Z\ensuremath{\le}12 from central collisions of $^{40}$ Ar${+}^{45}$Sc at incident energies ranging 35 to 115 MeV/nucleon. find that the can be described by a power law or an exponential and steepen increasing energy. Over range studied, average number intermediate mass decreases while particles increases. When combined previous results charge distributions, minimum is observed in extracted power-law parameter.
E896 has measured Lambda production in 11.6A GeV/c Au-Au collisions over virtually the whole rapidity phase space. The midrapidity p(t) distributions have been for first time at this energy and appear to indicate that hyperons different freeze-out conditions than protons. A comparison with relativistic quantum molecular dynamics model shows while there is good shape agreement high predicts significantly slopes of m(t) spectra midrapidity. data, where overlap occurs, are consistent previously...
This paper reports the elemental production cross sections for 17 projectile-energy combinations with energies between 338 and 894 MeV/nucleon interacting in a liquid hydrogen target. These results were obtained from two runs at LBL Bevalac using projectiles ranging $^{22}\mathrm{Ne}$ to $^{58}\mathrm{Ni}$. Cross measured all fragment elements charges greater than or equal half charge of projectile. The show that, over energy ion range investigated, general decrease section decreasing is...
A liquid hydrogen target was used to study the nuclear fragmentation of beams relativistic heavy ions, 22Ne 58Ni, over an energy range 400 900 MeV/nucleon. The experiments were carried out at Lawrence Berkeley Laboratory Bevalac HISS facility, using charge-velocity-rigidity method identify charged fragments. Here we describe general concept experiment and present total charge-changing cross sections obtained from 17 separate runs. These new measured display dependence which follows...
Multifragment azimuthal correlation functions have been measured as a function of beam energy and impact parameter for the Ar+Sc system (E/A=35 to 115 MeV). The observed functions---which do not require corrections dispersion reaction plane---exhibit strong asymmetries which are dependent on energy. Rotational collective motion flow seem dominate at low energies. It is proposed that multifragment can provide useful probe intermediate heavy ion dynamics.
We have added a new measurement at 100 MeV/nucleon to our previous excitation function for collective flow of light fragments from $^{40}\mathrm{Ar}$${+}^{51}$V collisions. In the earlier work, decreased as beam energy was raised 45 85 MeV/nucleon. This provided hints disappearance flow, but lack measurements higher energies precluded observation reappearance flow. At has reappeared and this allows an experimental determination region where attractive scattering balances with repulsive in...
Atypical haemolytic uraemic syndrome (aHUS) is associated with dysfunction of the alternative pathway complement. Disease activity subsides as renal failure progresses but recurs upon transplantation, indicating that viable tissue contributes to disease activity. We present evidence cerebrovascular occlusive vascular injury may occur in absence kidneys. A currently 12-year-old girl developed at age 20 months. She underwent bilateral nephrectomy and transplantation lost transplant due...
The interactions of ${}^{36}\mathrm{Ar}$ projectile nuclei with energies 361, 546, and 765 MeV/nucleon ${}^{40}\mathrm{Ar}$ 352 MeV/nucleon, have been studied in a liquid-hydrogen target as part program to study relevance the problem cosmic-ray propagation interstellar medium. We measured cross sections for production isotopic fragments these interactions. variations mass, charge, energy, are examined insights into any systematic features this type fragmentation reaction that might aid...
We have investigated particle production using a zero degree two-segment focusing beam-line spectrometer, examining 2×1012Au+Au interactions at beam momentum of 10.8AGeV/c. measured invariant cross sections for protons, various light nuclei (through A=6), antiprotons, and set upper limits on the heavier nuclei, antideuterons, strangelets. There is no evidence, within sensitivity our measurements, formation new particles having lifetimes >100nsReceived 21 March...

Subsequent CT, MRI DSA showed brain ischaemia oedema within the left cerebral hemisphere strict ipsilateral segmental arterial vasoconstriction. Despite extensive medical care, steroids, deteriorated rapidly. However, clinical course changed...

The data, which cover a broad rapidity range at low transverse momenta, were as function collision centrality using focusing beam line spectrometer high-rate detector. investigate dependence coalescence parameters on event geometry. data are compared with predictions an RQMD+coalescence model.
The isotopic production cross sections for ${}^{40}\mathrm{Ca}$ projectiles at 357, 565, and 763 MeV/nucleon interacting in a liquid hydrogen target have been measured by the Transport Collaboration LBL HISS facility. systematics of these are studied, results indicate that nuclear structure effects present isotope process during relativistic collisions. newly also compared with those predicted semiempirical parametric formulas, but predictions do not fully describe such as energy dependence....
