ThelR547v1—An Asymmetric Dilated Convolutional Neural Network for Real-time Semantic Segmentation of Horticultural Crops

Sensors, 2022
Robust and automated image segmentation in high-throughput image-based plant phenotyping has received considerable attention in the last decade. The possibility of this approach has not been well studied due to the time-consuming manual segmentation and ...

On the bifurcation and continuation of periodic orbits in the three-body problem

, 2011
We consider the planar three body problem of planetary type and we study the generation and continuation of periodic orbits and mainly of asymmetric periodic orbits. Asymmetric orbits exist in the restricted circular three body problem only in particular

Asymmetric Obligations [PDF]

SSRN Electronic Journal, 2011
We use a laboratory experiment to investigate the behavioral effects of obligations that are not backed by binding deterrent incentives. To implement such expressive law' we introduce different levels of very weakly incentivized, symmetric and asymmetric minimum contribution levels (obligations) in a repeated public goods experiment.

Dynamic Network Connectedness of Bitcoin Markets: Evidence from Realized Volatility

Frontiers in Physics, 2020
In this paper, we explore the volatility spillovers across different Bitcoin markets. We decompose the realized volatility into common and idiosyncratic volatilities, as well as the good and bad volatilities.

Global Collapses and Expansions in Star-Forming Clouds

, 2009
Spectral molecular line profile observations of star-forming molecular clouds sometimes show distinct red asymmetric double-peaked molecular line profiles with weaker blue peaks and stronger red peaks.

MCM-41-supported L-phenylalaninol as a chiral heterogeneous ligand in the enantioselective Kharasch-Sosnovsky reaction

Results in Chemistry
In this study, L-phenylalaninol, synthesized from the reduction of naturally occurring L-phenylalanine, was immobilized on MCM-41. The resulting heterogeneous ligand was comprehensively characterized using various spectroscopic techniques, such as FT-IR,
