[1] Explosivity of rhyolite domes depends on bubble nucleation and growth. To understand these processes, we measure millimeter-scale variations in H2O by synchrotron Fourier transform infrared (FTIR) spectromicroscopy on interlayered obsidian-pumice samples. The H2O contents of all samples are above the 1-atm solubility value ( 0.10wt.%) and decrease systematically towards vesicular zones, ind...

Introduction: In October 2004, SAR imaging from Cassini’s TA encounter uncovered features suggestive of cryovolcanic constructs on Titan, including flows, sinuous channels, and the 180 km structure Ganesa Macula [1]. Ganesa Macula is a radar-dark, circular feature with bright flanks, sinuous channels, and a bright region in the center that may be a central depression. In many ways, Ganesa Macul...

Pachycephalosaurian dinosaurs have dorsally thickened crania and uniquely shaped frontoparietal domes in some genera, suggested as evidence for heador flank-butting behavior. Trabeculae thought to have resisted impact compression are present as only one histological zone of some pachycephalosaur domes, and are surrounded superficially or replaced by thick compacta in adults. The capabilities of...

Mons Rümker is a large volcanic complex in Oceanus Procellarum on the Moon and is a candidate landing site for China’s Chang’E-5 sample return mission. We conducted a comprehensive study of the topography, geomorphology, composition, and stratigraphy of the Mons Rümker region with multisource remote sensing data in order to better understand the geology of the region and provide further support...

OBJECTIVE To describe in detail a technique to achieve cephalic rotation, projection, and narrowing of the nasal tip, the "new domes" technique. DESIGN Retrospective analysis of more than 3000 primary rhinoplasties performed during the last 20 years. SETTING A private facial plastic surgery practice in Bogotá, Colombia. INTERVENTION Through an endonasal cartilage delivery approach to the ...

Macroscopic T wave alternans (TWA) associated with increased occurrence of ventricular arrhythmias has been reported in patients with Brugada syndrome. However, the mechanisms in this syndrome are still unclear. We evaluated the hypothesis that TWA in Brugada syndrome was caused by the dynamic instability and heterogeneity of action potentials (APs) in the right ventricle. Using an optical mapp...

We describe a method for controllably generating giant balloon-like liposomes through electroformation of densely micro-patterned lipid films. These balloon-like liposomes are still tethered to the substrate through a thin lipid tube. We found that the patterns that were more densely spaced generated the balloon-like liposomes, whereas patterns that were sparsely spaced generated hemi-spherical...

BACKGROUND Relapsing fever (RF) spirochetes are notable for multiphasic antigenic variation of polymorphic outer membrane lipoproteins, a phenomenon responsible for immune evasion. An additional role in tissue localization is suggested by the finding that isogenic serotypes 1 (Bt1) and 2 (Bt2) of the RF spirochete Borrelia turicatae, which differ only in the Vsp they express, exhibit marked dif...

In Islamic culture, dome continues its ancient representation when it becomes a clear epitome of Islamic substantial creation of the universe. Islamic signs such as center, circle and sphere which are inherently dome are immediately realized via a symbolic transfer. Although domes have unavoidable relationship with other elements signifying Iranian mosques form and function, it includes secrets...
