Isolated calf muscular vein thrombosis is associated with pulmonary embolism and a high incidence of additional ipsilateral and contralateral deep venous thrombosis.

Journal of vascular surgery. Venous and lymphatic disorders

J Vasc Surg Venous Lymphat Disord. 2013 Jan;1(1):33-8. doi: 10.1016/j.jvsv.2012.04.001. Epub 2012 Dec 08.

OBJECTIVE: Little is known about the natural history of isolated gastrocnemial and soleal vein thrombosis (IGSVT), and recommendations for treatment and follow-up are therefore anecdotal. This study sought to determine the rates of venous thromboembolism (VTE) progression and resolution...

Atomistic clustering-ordering and high-strain deformation of an Al0.1CrCoFeNi high-entropy alloy.

Scientific reports

Sharma A, Singh P, Johnson DD, Liaw PK, Balasubramanian G.
PMID: 27498807
Sci Rep. 2016 Aug 08;6:31028. doi: 10.1038/srep31028.

Computational investigations of structural, chemical, and deformation behavior in high-entropy alloys (HEAs), which possess notable mechanical strength, have been limited due to the absence of applicable force fields. To extend investigations, we propose a set of intermolecular potential parameters...

Experiments and Model for Serration Statistics in Low-Entropy, Medium-Entropy, and High-Entropy Alloys.

Scientific reports

Sci Rep. 2015 Nov 23;5:16997. doi: 10.1038/srep16997.

High-entropy alloys (HEAs) are new alloys that contain five or more elements in roughly-equal proportion. We present new experiments and theory on the deformation behavior of HEAs under slow stretching (straining), and observe differences, compared to conventional alloys with...

Deviation from high-entropy configurations in the atomic distributions of a multi-principal-element alloy.

PMID: 25601270
Nat Commun. 2015 Jan 20;6:5964. doi: 10.1038/ncomms6964.

The alloy-design strategy of combining multiple elements in near-equimolar ratios has shown great potential for producing exceptional engineering materials, often known as 'high-entropy alloys'. Understanding the elemental distribution, and, thus, the evolution of the configurational entropy during solidification, is...

Effects of the Ar ions pre-amorphization of Si substrate on interface mixing of Fe/Si bilayers.

Journal of microscopy

Bibić N, Milinović V, Milosavljević M, Schrempel F, Siljegović M, Lieb KP.
PMID: 19094037
J Microsc. 2008 Dec;232(3):539-41. doi: 10.1111/j.1365-2818.2008.02143.x.

Ion beam mixing of Fe/Si bilayers, induced by 100 keV (40)Ar ions at room temperature was investigated. Rutherford backscattering spectroscopy (RBS), atomic force microscopy (AFM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were applied for structural characterization....

Strain-dependent deformation behavior in nanocrystalline metals.

Phys Rev Lett. 2008 Jul 04;101(1):015502. doi: 10.1103/PhysRevLett.101.015502. Epub 2008 Jul 03.

The deformation behavior as a function of applied strain was studied in a nanostructured Ni-Fe alloy using the in situ synchrotron diffraction technique. It was found that the plastic deformation process consists of two stages, undergoing a transition with...

Controlling oxygenation during initiation of cardiopulmonary bypass: can it improve immediate postoperative outcomes in cyanotic children undergoing cardiac surgery? A prospective randomized study.

World journal for pediatric & congenital heart surgery

World J Pediatr Congenit Heart Surg. 2012 Jul 01;3(3):310-6. doi: 10.1177/2150135111431843.

OBJECTIVE: Cardiopulmonary bypass (CPB) initiated with high oxygen levels may expose cyanotic children to reoxygenation injury. The ideal method of initiation of bypass to prevent this phenomenon still remains largely unproven. This study tested the hypothesis that controlling oxygenation...

A nanospheric polyhydrido copper cluster of elongated triangular orthobicupola array: liberation of H2 from solar energy.

An unprecedented air-stable, nanospheric polyhydrido copper cluster, [Cu20H11(S2P(O(i)Pr)2)9] (1H), which is the first example of an elongated triangular orthobicupola array of Cu atoms having C3h symmetry, was synthesized and characterized. Its composition was primarily determined by electrospray ionization mass...

The issue, composition dependence of glass-forming ability (GFA) in metallic glasses (MG), has been investigated by systematic experimental measurements coupled with theoretical calculations in Cu-Zr and Ni-Nb alloy systems. It is found that the atomic-level packing efficiency strongly relates...
