Substrate Drench Applications of Flurprimidol and Paclobutrazol Influence Growth of Swamp Sunflower

open access: yesHortTechnology, 2019
Swamp sunflower (Helianthus simulans) is an underused perennial plant native to the southeastern United States that produces an abundance of golden yellow inflorescences in the fall. It is a vigorous grower and tolerates a wide variety of soil conditions,

Characterization of a commercially available large area, high detection efficiency single-photon avalanche diode

open access: yes, 2013
We characterize a new commercial, back-illuminated reach-through silicon single-photon avalanche photo diode (SPAD) SAP500 (Laser Components. Inc.), operated in Geiger-mode for purpose of photon counting.

Use of a Chlorophyll Meter for Nondestructive and Rapid Estimation of Leaf Tissue Nitrogen in Macadamia

open access: yesHortTechnology, 2019
Nitrogen (N) management in macadamia (Macadamia integrifolia) orchards is an important concern for growers. Leaf tissue analysis is the accepted method for determining N status in macadamia; however, this process is expensive and time-consuming.

2.23 GHz gating InGaAs/InP single-photon avalanche diode for quantum key distribution

open access: yes, 2010
We implement an InGaAs/InP single-photon avalanche diode (SPAD) for single-photon detection with the fastest gating frequency reported so far, of 2.23 GHz, which approaches the limit given by the bandwidth of the SPAD - 2.5 GHz.

Two-photon interference using background-free quantum frequency conversion of single photons from a semiconductor quantum dot

open access: yes, 2012
We show that quantum frequency conversion (QFC) can overcome the spectral distinguishability common to inhomogeneously broadened solid-state quantum emitters.

Immunological characterization and transcription profiling of peripheral blood (PB) monocytes in children with autism spectrum disorders (ASD) and specific polysaccharide antibody deficiency (SPAD): case study

open access: yesJournal of Neuroinflammation, 2012
Introduction There exists a small subset of children with autism spectrum disorders (ASD) characterized by fluctuating behavioral symptoms and cognitive skills following immune insults. Some of these children also exhibit specific polysaccharide antibody

Automatic retrieval of crop characteristics: an example for hyperspectral AHS data from the AgriSAR campaign. [PDF]

open access: yes, 2007
This paper presents the results of automated extraction of crop characteristics from hyperspectral earth observation data. The data was acquired with an airborne AHS imaging spectrometer in the framework of the joint European AgriSAR 2006 campaign.

Spatiotemporal Exciton Tracking with a SPAD Camera

open access: yesACS Photonics
Spatiotemporal microscopy plays an important role in the quest for highly efficient light harvesting materials as it allows direct tracking of the nanoscale transport of excitons, the carriers of the photon energy. Unfortunately, achieving high resolution in both space and time often requires scanning beam spots or delay lines, limiting these ...
