S U M M A R Y Since the end of the 1970s, teleseismic waves are used routinely to infer the first-order characteristics of the event (location, depth, duration, focal mechanism), but finding the second-order kinematic parameters (spatial distribution of slip, rupture velocity and more basically the discrimination between the fault plane and the other nodal plane) of distant events remains a dif...

In nuclear power plants (NPPs), one of the important yet uncertain phenomena during a station blackout (SBO) accident is possibility for counter-current natural circulation flow in reactor coolant system (RCS) pressure boundary, which could divert core melt progression and/or in-vessel fission product (FP) distribution and, turn, lead to heatup and eventual creep rupture. From risk management p...

Deep earthquakes occur down to 700 km depth where pressure is up two orders of magnitude greater than in the crust. Rupture characteristics and propagation mechanisms under those extreme conditions are still poorly constrained. We invert seismic waveforms for spatial dimensions, duration stress drop deep-focus (Mw 6.7–7.7) Kuril subduction zone. find drops ?1–10 MPa rigidity-corrected dimension...

Abstract Objectives To describe and review a series of penile trauma. Methods Patients with suspicions fracture that received surgical treatment were included from 2015 to 2022. Characteristics collected: date birth, type affected parts the penis, evolution after surgery. Description complications outcomes. Results 11 consecutive patients due suspicion 3 had negative previous ultrasonography. s...

A postmyocardial infarction left ventricular pseudoaneurysm occurs when a rupture of the ventricular free wall is contained by overlying, adherent pericardium. A postinfarction aneurysm, in contrast, is caused by scar formation resulting in thinning of the myocardium. Although the usual treatment for patients with pseudoaneurysm is urgent surgical repair, the imaging characteristics of pseudoan...

High-intensity focused ultrasound (HIFU) has been emerging as an effective and noninvasive modality in cancer treatment with very promising clinical results. However, a small vessel in the focal region could be ruptured, which is an important concern for the safety of HIFU ablation. In this study, lesion formation in the polyacrylamide gel phantom embedded with different tubing (inner diameters...

The rupture risk of unruptured intracranial aneurysms is known to be dependent on the size of the aneurysm. However, the association of morphological characteristics with ruptured aneurysms has not been established in a systematic and location specific manner for the most common aneurysm locations. We evaluated posterior communicating artery (PCoA) aneurysms for morphological parameters associa...

BACKGROUND AND PURPOSE Size and shape of saccular intracranial aneurysms (sIA) reflect the condition of the sIA wall and were risk factors for rupture in previous follow-up studies. We investigated how well size or shape identify rupture-prone sIAs. METHODS In a population-based registry, we investigated the characteristics of ruptured sIAs treated in a single neurosurgical center (1980-2014)...
