Spatially Modulated Morphotropic Phase Boundaries in a Compressively Strained Multiferroic Thin Film

Advanced Functional Materials, EarlyView.
ABSTRACT The coexisting rhombohedral‐like (R′, MA) and tetragonal‐like (T′, MC) monoclinic phases in compressively strained bismuth ferrite thin films exhibit exceptional piezoelectric and magnetic properties. While previous studies have largely focused on probing the morphotropic phase boundaries (MPBs) comprising ordered R′/T′ twins, their self ...

SENSE and simultaneous multislice imaging [PDF]

Magnetic Resonance in Medicine, 2014
PurposeSimultaneous multislice (SMS) acquisitions play an important role in the challenge of increasing single‐shot imaging speed. We show that sensitivity encoding in two spatial dimensions (two‐dimensional sensitivity encoding [2D‐SENSE]) can be used to reconstruct SMS acquisitions with periodic but otherwise arbitrary undersampling patterns.Theory ...

Multislice CT of Jaw Swelling

SVU - International Journal of Medical Sciences
Background: Multi-detector line CT (MDCT) has converted CT from the cross-sectional into a fully three-dimensional image. MDCT scans quickly acquire multiple thin axial images, as well as more precise images of rebuilding.

Cell Segmentation Beyond 2D—A Review of the State‐of‐the‐Art

Advanced Intelligent Discovery, EarlyView.
Cell segmentation underpins many biological image analysis tasks, yet most deep learning methods remain limited to 2D despite the inherently 3D nature of cellular processes. This review surveys segmentation approaches beyond 2D, comparing 2.5D and fully 3D methods, analyzing 31 models and 32 volumetric datasets, and introducing a unified reference ...

Maghemite-like regions at crossing of two antiphase boundaries in doped BiFeO3 [PDF]

, 2015
We report the observation of a novel structure at the point where two antiphase boundaries cross in a doped bismuth ferrite of composition (Bi0.85Nd0.15)(Fe0.9Ti0.1)O0.3. The structure was investigated using a combination of high angle annular dark field

Correlation of Multislice CT and Biopsy in Diagnosis of Jaw Swelling

SVU - International Journal of Medical Sciences
Background: Radiography appears to be a promising way of investigating jaw lesions. Multi-detector CT (MDCT) scan, due to its sensitivity and diagnostic performance, is widely performed for different types of maxilla and mandible swellings.

Inside a duck‐billed dinosaur: Vertebral bone microstructure of Huallasaurus (Hadrosauridae), Upper Cretaceous of Patagonia

The Anatomical Record, EarlyView.
Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

Determining On-Axis Crystal Thickness with Quantitative Position-Averaged Incoherent Bright-Field Signal in an Aberration-corrected STEM

, 2012
An accurate determination of specimen thickness is essential for quantitative analytical electron microscopy. Here we demonstrate that a position-averaged incoherent bright-field signal recorded on an absolute scale can be used to determine the thickness
