Plants, 2022 Cannabis is one of the oldest cultivated plants, but plant breeding and cultivation are restricted by country-specific regulations. The plant has gained interest due to its medically important secondary metabolites, cannabinoids and terpenes.

Lenses for Light Distribution [PDF]
Proceedings of the Physical Society of London, 1915 The principle on which lenses for securing a required distribution of light from a given source have been designed is illustrated by a two-dimensional example. The principle employed is to divide the incident and emergent energy into a number of equal parts, and compute the lens system so that the rays which separate off these portions of incident ...

Six-dimensional light-front Wigner distributions of the proton
European Physical Journal C: Particles and FieldsWe investigate six-dimensional quark Wigner distributions of the proton in a light-front quark spectator-diquark model. Benefiting from the light-front boost-invariant longitudinal variable $$\tilde{z}$$ z ~ , these light-front Wigner distributions ...

Higher twist parton distributions from light-cone wave functions
, 2011 We explore the possibility to construct higher-twist parton distributions in a nucleon at some low reference scale from convolution integrals of the light-cone wave functions (WFs). To this end we introduce simple models for the four-particle nucleon WFs

Gluon Wigner distributions in a light-cone spectator model
European Physical Journal C: Particles and FieldsWe study the gluon Wigner distributions of the proton which are the phase-space distributions containing the most general one-parton information. Using the proton wave functions deduced from a light-cone spectator model that contains the gluonic degree ...

The Charge and Matter radial distributions of Heavy-Light mesons calculated on a lattice [PDF]
, 2001 For a heavy-light meson with a static heavy quark, we can explore the light quark distribution. The charge and matter radial distributions of these heavy-light mesons are measured on a 16^3 * 24 lattice at beta=5.7 and a hopping parameter corresponding ...

Angular distribution of diffusely transmitted light
Physical Review E, 1996 The angular dependence of light diffusely transmitted through an opaque medium is shown to depend directly on the reflective nature of the sample boundary, independent of scattering anisotropy. Experimental data are presented for glass frits and for liquid samples, such as colloidal suspensions and aqueous foams, contained in glass cells and placed in ...

Phenomenology of the Flavor-Asymmetry in the Light-Quark Sea of the Nucleon [PDF]
, 2000 A phenomenological ansatz for the flavor-asymmetry of the light sea distributions of the nucleon, based on the Pauli exclusion principle, is proposed.

Distributed dimming control for LED lighting
Optics Express, 2013 This paper presents a distributed energy-saving lighting strategy for the arrangements of a lighting network consisting of a group of light-emitting diode (LED) lamps and users. LED lamps have a dimming support feature to meet the illuminance requirements imposed by individual users. Both groups interact with each other via visible light communication (

Nature Communications, 2023 The orientation of luminescent molecules in organic light-emitting diodes strongly influences device performance. However, our understanding of the factors controlling emitter orientation is limited as current measurements only provide ensemble-averaged ...
