Determining candidate polyp morphology from CT colonography using a level-set method [PDF]

, 2005
In this paper we propose a level-set segmentation for polyp candidates in Computer Tomography Colongraphy (CTC). Correct classification of the candidate polyps into polyp and non-polyp is, in most cases, evaluated using shape features.

α-Synuclein Induces Both Positive Mean Curvature and Negative Gaussian Curvature in Membranes

, 2016
Using a combination of X-ray scattering, fluorescence correlation spectroscopy, coarse-grained molecular dynamics (MD) simulations and potential of mean force calculations, we have explored the membrane remodeling effects of monomeric α-synuclein (αS ...

Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

Advanced Materials, EarlyView.
The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

Investigation on Non-Gaussian Peak Factors for Wind Pressures on Domed Roof Structures

, 2016
Roof curvature and Reynolds number effect significantly define the characteristics of wind pressures on domed roof structures. Once the flow separates from the roof surface, apparent changes in aerodynamic coefficients or non-Gaussian wind-induced ...

2D Co‐Mo‐Hydroxide‐Based Multifunctional Material for the Development of H2‐Based Clean Energy Technologies

Advanced Materials, EarlyView.
2D α‐Co(OH)2 interleaved with Mo species displays an appealing dual functionality for the production and use of green hydrogen.Mo incorporation greatly benefits the electrochemical behaviour in Oxygen Evolution Reaction for H2 production, while the magnetocaloric response at liquid H2 temperature paves the way for alternative cryogenic refrigerants ...

Analysis of Geometry and Strength of Shells with Middle Surfaces Defined by Two Superellipses and a Circle

Structural Mechanics of Engineering Constructions and Buildings
In this study, thin shells in the form of algebraic surfaces defined by a geometric frame of three plane superellipses lying respectively in three coordinate planes are considered. As the main focus of the study, the case when the horizontal superellipse

High Light Utilization and Color Rendering in Vacuum‐Deposited Semitransparent Perovskite Solar Cells

Advanced Materials, EarlyView.
In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...
