Polarity Inversion in Polar-Nonpolar-Polar Heterostructures [PDF]

open access: yesPhysical Review Letters, 2001
We have observed an epilayer-thickness-dependent polarity inversion for the growth of CdTe on Sb(Bi)/CdTe(111)B. For films with Sb(Bi) thicknesses of less than 40 A (15 A), the CdTe layer shows a B (Te-terminated) face, but it switches to an A (Cd-terminated) face for thicker layers.

Polarization and Polar Codes [PDF]

open access: yesFoundations and Trends® in Communications and Information Theory, 2012
This tutorial treats the fundamentals of polarization theory and polar coding. Arikan’s original results on binary source and channel polarization methods are studied. Error probability and complexity analyses are offered. The original results are generalized in several directions.

Universal Polarization [PDF]

open access: yesIEEE Transactions on Information Theory, 2014
A method to polarize channels universally is introduced. The method is based on combining two distinct channels in each polarization step, as opposed to Arikan's original method of combining identical channels. This creates an equal number of only two types of channels, one of which becomes progressively better as the other becomes worse. The locations

Polar shapelets [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2005
The shapelets method for image analysis is based upon the decomposition of localised objects into a series of orthogonal components with convenient mathematical properties. We extend the "Cartesian shapelet" formalism from earlier work, and construct "polar shapelet" basis functions that separate an image into components with explicit rotational ...

Light-Induced Protein Clustering for Optogenetic Interference and Protein Interaction Analysis in Drosophila S2 Cells

open access: yesBiomolecules, 2019
Drosophila Schneider 2 (S2) cells are a simple and powerful system commonly used in cell biology because they are well suited for high resolution microscopy and RNAi-mediated depletion.

Unified quantitative characterization of epithelial tissue development

open access: yeseLife, 2015
Understanding the mechanisms regulating development requires a quantitative characterization of cell divisions, rearrangements, cell size and shape changes, and apoptoses.

Integration of Core Mechanisms Underlying Plant Aerial Architecture

open access: yesFrontiers in Plant Science, 2021
Over the last decade or so important progress has been made in identifying and understanding a set of patterning mechanisms that have the potential to explain many aspects of plant morphology.

Polarized cells, polar actions

open access: yesJournal of Bacteriology, 1993
The recognition of polar bacterial organization is just emerging. The examples of polar localization given here are from a variety of bacterial species and concern a disparate array of cellular functions. A number of well-characterized instances of polar localization of bacterial proteins, including the chemoreceptor complex in both C. crescentus and E.
