Cortical sulci model and matching from 3D brain magnetic resonance images [PDF]

open access: yes, 1995
International audiencePositron emission tomography (PET) is one of the most popular techniques for the study of brain functional activity. Several studies show that PET is an in-vivo examination technique able to produce real images of cerebral activity,

The X-ray luminosity function of M37 and the evolution of coronal activity in low-mass stars

open access: yes, 2016
We use a 440.5 ks Chandra observation of the $\approx$500-Myr-old open cluster M37 to derive the X-ray luminosity functions of its $\leq1.2$ $M_{\odot}$ stars. Combining detections of 162 M37 members with upper limits for 160 non-detections, we find that

A review of one-step fluorescent cyanoacrylate techniques [PDF]

open access: yes, 2016
A review of recent research in the use of one-step fluorescent cyanoacrylate techniques is presented. Advantages and disadvantages of such techniques in comparison to two-step processes are discussed.

Microwave treatment of the cornea leads to localised disruption of the extracellular matrix [PDF]

open access: yes, 2018
Microwave keratoplasty is a thermo-refractive surgical procedure that can correct myopia (short-sightedness) and pathologic corneal steepening by using microwave energy to cause localised shrinkage around an annulus of the cornea leading to its ...

Transthoracic 3D echocardiographic left heart chamber quantification in patients with bicuspid aortic valve disease [PDF]

open access: yes, 2017
Integration of volumetric heart chamber quantification by 3D echocardiography into clinical practice has been hampered by several factors which a new fully automated algorithm (Left Heart Model, (LHM)) may help overcome.

Green stabilization of microscale iron particles using guar gum: bulk rheology, sedimentation rate and enzymatic degradation [PDF]

open access: yes, 2014
Guar gum can be used to effectively improve stability and mobility of microscale zerovalent iron particles (MZVI) used in groundwater remediation. Guar gum is a food-grade, environment friendly natural polysaccharide, which is often used as thickening ...
