Pyramidic Mesophases

open access: yesZeitschrift für Naturforschung A, 1985
Two series of mesogenic compounds consisting of a rigid pyramidal central core and six equal flexible side chains were synthesized and their mesomorphic properties studied by calorimetry and optical microscopy. The two series of compounds are: I-hexaalkyloxytribenzocyclononene and II-hexaalkanoyloxytribenzocyclononene.

Drivers of adoption of reuse-on-the-go systems among low-income consumers in Kenya: insights from key expert entrepreneurs using the Theoretical Domains Framework and COM-B model

open access: yesFrontiers in Sustainability
IntroductionReusable systems can reduce plastic pollution from single-use packaging in fast-moving consumer goods in the Global South. While both “at-home” and “on-the-go” models exist, the latter requires greater consumer effort, as users must regularly

Recovering pyramid WS gain in non-common path aberration correction mode via deformable lens

open access: yes, 2017
It is by now well known that pyramid based wavefront sensors, once in closed loop, have the capability to improve more and more the gain as the reference natural star image size is getting smaller on the pyramid pin. Especially in extreme adaptive optics

A Reverse Hierarchy Model for Predicting Eye Fixations [PDF]

open access: yes, 2014
A number of psychological and physiological evidences suggest that early visual attention works in a coarse-to-fine way, which lays a basis for the reverse hierarchy theory (RHT).

Interactions Between Lr67 or Lr34 and Other Leaf Rust Resistance Genes in Wheat (Triticum aestivum)

open access: yesFrontiers in Plant Science, 2022
The wheat multi-pest resistance genes Lr67 and Lr34 are similar in that they both condition resistance to many diseases, in a non-race-specific manner, and code for cellular transporters.

Variation around a Pyramid theme: optical recombination and optimal use of photons

open access: yes, 2015
We propose a new type of Wave Front Sensor (WFS) derived from the Pyramid WFS (PWFS). This new WFS, called the Flattened Pyramid-WFS (FPWFS), has a reduced Pyramid angle in order to optically overlap the four pupil images into an unique intensity.

Spatial distribution of Gaussian fluctuations of the molecular field and magnetization in the pyramid-like Ising nanoscopic system interacting with the substrate

open access: yes, 2009
We study thermodynamic properties of an Ising model of a ferromagnetic nanoscopic pyramid deposited onto a ferromagnetic bulk substrate. The influence of the interaction between the pyramid and the substrate is calculated in terms of the equilibrium ...

Phase transitions in nanosystems caused by interface motion: The Ising bi-pyramid with competing surface fields [PDF]

open access: yes, 2005
The phase behavior of a large but finite Ising ferromagnet in the presence of competing surface magnetic fields +/- H_s is studied by Monte Carlo simulations and by phenomenological theory.
