Figure 1. Chest computed tomography-scan. Note the loop around the heart (1) and elongated segment of the probe (2). 1 2 We report the case of a 49 year-old man, admitted to our institution for tamponade. His previous medical history was mainly an oesophageal epidermoid cancer, with local metastases treated by chemotherapy and radiotherapy, and oesophageal prosthesis. His cardiovascular risk fa...

To assess the contribution of apoptosis to the mechanism of synovial joint cavitation, and to clarify morphological cellular changes during cavitation, we investigated the development of the rat knee joint by light and electron microscopy, TUNEL methods, and electrophoresis of DNA fragments. Although cavitation occurred within the interzone, which consists of 2 outer and a middle layer termed t...

Flattened Gaussian beams are characterized by a waist profile that passes in a continuous way from a nearly flat illuminated region to darkness. The steepness of the transition region is controlled by an integer parameter N representing the order of the beam. Being expressible as a sum of N Laguerre–Gauss modes, a flattened Gaussian beam turns out to be very simple to study as far as propagatio...

Abstract Mitigation of long-lived mode (LLM) by lower hybrid wave (LHW) is recently achieved on the HL-2A tokamak. The LLM changes from a typical steady-state to fishbone-like frequency-chirping characteristic, and its higher poloidal harmonics disappear when LHW injected into toroidal plasma. It found that density fluctuation declines during this process while total neutron count increases gra...

One of the most extensive species radiations in tardigrade evolution took place Echiniscus phylogenetic line, which contains genus with over 120 described to date. The internal classification is historically based on two major sources variability: chaetotaxy, that arrangement and shape trunk appendages, sculpturing dorsal plates. These criteria allowed for delineation complexes, such as blumi-c...

AC-rewriting is simulated by using flattened terms, flattened rewrite rules, extensions and specializations with respect to the AC-operators, therefore allowing us to reduce AC-pattern matching and AC-unification to permutative matching and permutative unification respectively.

This study presents the basic dosimetric properties of photon beams of a Versa HD linear accelerator (linac), which is capable of delivering flattening filter-free (FFF) beams with a beam quality equivalent to the corresponding flattened beams based on comprehensive beam data measurement. The analyzed data included the PDDs, profiles, penumbra, out-of-field doses, surface doses, output factors,...
