Achieving the High Color Conversion Efficiency by Using Efficient Energy Transfer Rates in Organic Nanocrystals

open access: yesSmall Structures
Color conversion materials for next‐generation displays are fundamentally limited by architectures that rely on direct blue‐light absorption, requiring high‐emitter loading, thick films which often suffer from residual blue leakage, and instability. Here,

www.ijerd.com RGB to YCbCr Color Conversion using VHDL approach

open access: yes, 2014
––In this paper, we present the architecture and design of a color space conversion module. The color space converter module is used for changing the image from RGB color space to YCbCr color space.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

A New Phenomenon in Color Conversion. [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1906
Minot, N. D., Aug. 1, 1906. To the Editor: —I wish to make some suggestions in connection with the Stevens' phenomenon, inasmuch as no entirely satisfactory explanation has been given, and with the hope that some element in them will lead to a further understanding of these color changes.

Gradient domain salience-preserving color-to-gray conversion

open access: yes, 2012
In this paper an algorithm for gradient domain color-to-gray conversion is described. By enhancing the luminance gradient with the chromatic difference in CIELAB space, a gradient field is created to construct the resulting gray-scale image using a ...

C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

open access: yesFEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

Transparent organic light-emitting diodes with different bi-directional emission colors using color-conversion capping layers

open access: yes, 2015
We report a study on transparent organic light-emitting diodes (OLEDs) with different bidirectional emission colors, enabled by color-conversion organic capping layers. Starting from a transparent blue OLED with an uncapped Ag top electrode exhibiting an

InGaN blue resonant cavity micro-LED with RGY quantum dot layer for broad gamut, efficient displays

open access: yesDiscover Nano
The technology of RGBY micro resonant cavity light emitting diodes (micro-RCLEDs) based on quantum dots (QDs) is considered one of the most promising approaches for full-color displays.

Estimation of the device gamut of a digital camera in raw performance using optimal color-stimuli [PDF]

open access: yes, 2003
Using a spectroradiometric model of capture for a digital camera based on the mathematical description of the empirical opto-electronic conversion spectral functions (OECSF), the capture of MacAdam or optimal spectra with fixed illumination level is ...
