Inherent Holography In Fuzzy Spaces and An N-tropic Approach To The Cosmological Constant Problem [PDF]

open access: yes, 2006
In this letter we show that the noncommutative spaces, and in particular fuzzy spheres, are natural candidates which explicitly exhibit the holography, by noting that the smallest physically accessible volume is much larger that the expected Planckian ...

X‐ray magnetic circular dichroism

open access: yesMajor Reference Works, Page 508-515., 2022
International Tables for Crystallography is the definitive resource and reference work for crystallography and structural science.

Each of the eight volumes in the series contains articles and tables of data relevant to crystallographic research and to applications of crystallographic methods in all sciences concerned with the ...

Using a holographic imager on a tethered balloon system for microphysical observations of boundary layer clouds [PDF]

open access: yesAtmospheric Measurement Techniques, 2020
Conventional techniques to measure boundary layer clouds such as research aircraft are unable to sample in orographically diverse or densely populated areas.

The artistic use of parallax and lenses revealing the invisible in holography [PDF]

open access: yes, 2012
There are many artistic resources offered by holography: third-dimension registration and reconstruction, immateriality, color interpretation, holographic space, realism, etc.

Absorbing new subjects: holography as an analog of photography [PDF]

open access: yes, 2006
I discuss the early history of holography and explore how perceptions, applications, and forecasts of the subject were shaped by prior experience. I focus on the work of Dennis Gabor (1900–1979) in England,Yury N. Denisyuk (1927-2005) in the Soviet Union,

Novel Perspectives on the Characterization of Species-Dependent Optical Signatures of Bacterial Colonies by Digital Holography. [PDF]

open access: yesPLoS ONE, 2016
The use of light diffraction for the microbiological diagnosis of bacterial colonies was a significant breakthrough with widespread implications for the food industry and clinical practice.

Holographic Protection of Chronology in Universes of the Godel Type [PDF]

open access: yes, 2002
We analyze the structure of supersymmetric Godel-like cosmological solutions of string theory. Just as the original four-dimensional Godel universe, these solutions represent rotating, topologically trivial cosmologies with a homogeneous metric and ...

On the Space-Time Uncertainty Principle and Holography [PDF]

open access: yes, 1998
In this note further evidence is collected in support of the claim that the space-time uncertainty principle implies holography, both within the context of Matrix Theory and the framework of the proposed duality between certain conformal field theories ...

Three-dimensional spatiotemporal focusing of holographic patterns

open access: yesNature Communications, 2016
Three-dimensional computer-generated holography cannot be implemented with temporal focusing. Here, Hernandez et al. use two spatial light modulators to control transverse- and axial-target light distribution, generating spatiotemporally focused patterns

Moment‐Based Shape‐Learning Holography for Fast Classification of Microparticles

open access: yesAdvanced Photonics Research, 2023
Compact computational in‐line holography based on deep learning is an attractive single‐shot approach to image microparticles dispersed in 3D volume. The particle shape contains valuable information for species classification, but the dataset acquisition
