Type‐II Dirac Fermions in Monolayer In2O: Interplay of Magnetotransport, Spin Hall Effect, and Superconductivity

Advanced Science, EarlyView.
First‐principles calculations reveal that monolayer In2O${\rm In}_2{\rm O}$ hosts type‐II Dirac fermions near the Fermi level, which split into Weyl points under spin‐orbit coupling. The material exhibits negative and giant magnetoresistance, a pronounced spin Hall effect, and phonon‐mediated superconductivity at 1.5 K, establishing it as a unique ...

Thick slice and thin slice teaching evaluations

Social Psychology of Education, 2009
Student-based teaching evaluations are an integral component to institutions of higher education. Previous work on student-based teaching evaluations suggest that evaluations of instructors based upon “thin slice” 30-s video clips of them in the classroom correlate strongly with their end of the term “thick slice” student evaluations.

Spread of activity in thick cortical slices

Brain Research, 1984
Slices of the hamster cerebral cortex 700-800 micron thick have been demonstrated to be viable when maintained in a bath perfused with oxygenated CSF at 30 ml/min. In such thick slices activity has been shown to spread over both hemispheres following stimulation of the corpus callosum; and seizure activity, suggestive of epilepsy, can be induced by the

Slice thickness reduction by partial overlapping presaturation

Magnetic Resonance in Medicine, 1992
AbstractWe present a new approach to slice thickness reduction that does not require strengthening the selection gradient or increasing the RF pulse duration. The basis of the approach is to employ a thick slice and suppress a portion of its width, thereby forming a thin slice.

Cytokeratin demonstration in thick breast tissue slices

The Histochemical Journal, 1997
Tissue slices (500 to 1000 microns thick) of archival formalin-fixed, paraffin-embedded breast tissue were immunostained by a cytokeratin antibody (MNF116) using a streptavidin-biotin complex procedure. The technique requires prolonged exposure of tissue slices to the reagents. Use of the detergent Triton X-100 facilitated penetration of high molecular

Slice‐thickness artifacts in gray‐scale ultrasound

Journal of Clinical Ultrasound, 1981
AbstractWe have become increasingly aware of the presence of a type of image artifact normally appearing in anechoic areas (eg, cyst, bladder, gallbladder) and giving the appearance of “sludge” or “debris.” These artifactual echoes may be caused by the fact that the finite width of the transducer beam pattern produces a finite thickness of the patient ...

Slice thickness measurements.

Journal of Ultrasound in Medicine, 1988
A new slice thickness test object is discussed, with results of feasibility tests using 13 transducers from six different commercial scanners presented. Both inplane beamwidth and slice thickness measurements could be easily performed and interpreted.

Effects of tomographic motion, slice thickness, and object thickness on film density

Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, 1996
The experiment used the computer-aided CommCat model IS 2000 tomographic machine (Imaging Sciences International, Roebling, N.J.). The objective of the experiment was to study the influence of tomographic tube motion, tomographic slice thickness, and object thickness on film density.
