Impact of incomplete ventricular coverage on diagnostic performance of myocardial perfusion imaging. [PDF]

, 2017
In the context of myocardial perfusion imaging (MPI) with cardiac magnetic resonance (CMR), there is ongoing debate on the merits of using technically complex acquisition methods to achieve whole-heart spatial coverage, rather than conventional 3-slice ...

A Novel in situ Approach to Studying Pancreatic Ducts in Mice

Frontiers in Physiology, 2019
Introduction: The tissue slice technique offers several benefits compared to isolated cells and cell clusters that help us understand the (patho)physiology of several organs in situ.

Slice Stretching at the Event Horizon when Geodesically Slicing the Schwarzschild Spacetime with Excision [PDF]

, 2004
Slice-stretching effects are discussed as they arise at the event horizon when geodesically slicing the extended Schwarzschild black-hole spacetime while using singularity excision. In particular, for Novikov and isotropic spatial coordinates the outward

KATP channels modulate intrinsic firing activity of immature entorhinal cortex layer III neurons

Frontiers in Cellular Neuroscience, 2014
Medial temporal lobe structures are essential for memory formation which is associated with coherent network oscillations. During ontogenesis, these highly organized patterns develop from distinct, less synchronized forms of network activity.

Adaptive slices for acquisition of anisotropic BRDF

Computational Visual Media, 2018
BRDF continues to be used as a fundamental tool for representing material appearance in computer graphics. In this paper we present a practical adaptive method for acquisition of anisotropic BRDF, based on sparse adaptive measurement of the complete four-

Diagnostic accuracy of magnetic resonance imaging for partial tears of the long head of the biceps tendon in patients with rotator cuff tears

JSES International, 2022
Background: Magnetic resonance imaging (MRI) is useful for diagnosing shoulder diseases preoperatively. However, detection of partial tears of the long head of the biceps tendon (LHBT) using current clinical tests and imaging modalities is difficult.

Partial slice regularity and Fueter's theorem in several quaternionic variables

Complex Manifolds, 2023
We extend some definitions and give new results about the theory of slice analysis in several quaternionic variables. The sets of slice functions that are slice, slice regular, and circular with respect to given variables are characterized.

Capturing Behavior in Small Doses: A Review of Comparative Research in Evaluating Thin Slices for Behavioral Measurement

Frontiers in Psychology, 2021
Thin slices are used across a wide array of research domains to observe, measure, and predict human behavior. This article reviews the thin-slice method as a measurement technique and summarizes current comparative thin-slice research regarding the ...

Slicing, sampling, and distance-dependent effects affect network measures in simulated cortical circuit structures

Frontiers in Neuroanatomy, 2014
The neuroanatomical connectivity of cortical circuits is believed to follow certain rules, the exact origins of which are still poorly understood. In particular, numerous nonrandom features, such as common neighbor clustering, overrepresentation of ...

Cerebellar nuclei neurons show only small excitatory responses to optogenetic olivary stimulation in transgenic mice: in vivo and in vitro studies

Frontiers in Neural Circuits, 2016
To study the olivary input to the cerebellar nuclei (CN) we used optogenetic stimulation in transgenic mice expressing channelrhodopsin-2 (ChR2) in olivary neurons.
