Bat eyes have ultraviolet-sensitive cone photoreceptors [PDF]

open access: yes, 2009
Mammalian retinae have rod photoreceptors for night vision and cone photoreceptors for daylight and colour vision. For colour discrimination, most mammals possess two cone populations with two visual pigments (opsins) that have absorption maxima at short

Retinal cone photoreceptors of the deer mouse Peromyscus maniculatus : development, topography, opsin expression and spectral tuning [PDF]

open access: yes, 2013
A quantitative analysis of photoreceptor properties was performed in the retina of the nocturnal deer mouse, Peromyscus maniculatus, using pigmented (wildtype) and albino animals.

Light-cone matrix product [PDF]

open access: yesJournal of Mathematical Physics, 2009
We show how to combine the light-cone and matrix product algorithms to simulate quantum systems far from equilibrium for long times. For the case of the XXZ spin chain at Δ=0.5, we simulate to a time of ≈22.5. While part of the long simulation time is due to the use of the light-cone method, we also describe a modification of the infinite time-evolving

The Gauge-Field Propagator in Light-Cone Gauge: Which is the Correct One? [PDF]

open access: yes, 2017
In the literature one can find two different expressions for the gauge-field propagator in light-cone gauge, containing the sum of three rather than two terms. The question of which of the two is the correct one has been a subject of debate. We propose a

Developmental dynamics of cone photoreceptors in the eel [PDF]

open access: yes, 2009
Background: Many fish alter their expressed visual pigments during development. The number of retinal opsins expressed and their type is normally related to the environment in which they live.

Gluon structure function in hamiltonian lattice QCD

open access: yes, 2022
Art. 040We calculate the gluon structure function of a color dipole in a new approach evaluating the matrix elements of SU(2) gluon field operators separated along a direction close to the light cone.

Light-front quantization with the light cone gauge [PDF]

open access: yesCanadian Journal of Physics, 2016
The Dirac procedure for dealing with constraints is applied to the quantization of gauge theories on the light front. The light cone gauge is used in conjunction with the first-class constraints that arise and the resulting Dirac brackets are found. These gauge conditions are not used to eliminate degrees of freedom from the action prior to applying ...

Light-cone Wilson loop in classical lattice gauge theory [PDF]

open access: yes, 2013
The transverse broadening of an energetic jet passing through a non-Abelian plasma is believed to be described by the thermal expectation value of a light-cone Wilson loop.
