Degree of Diffraction for Monochromatic Light Beams [PDF]

open access: yesACTA PHOTONICA SINICA, 2015
A parameter, called the degree of diffraction, is defined to describe the diffractive spreading of a monochromatic light beam. The same as the degree of paraxiality that was introduced by Gawhary and Severini in Opt. Lett. 33, 1360 (2008), the degree of diffraction depends only on beam's angular spectrum.

Vortex knots in light [PDF]

open access: yes, 2005
Optical vortices generically arise when optical beams are combined. Recently, we reported how several laser beams containing optical vortices could be combined to form optical vortex loops, links and knots embedded in a light beam (Leach et al 2004 ...

Monochromic light reduces emergence delirium in children undergoing adenotonsillectomy; a double-blind randomized observational study

open access: yesBMC Anesthesiology, 2021
Background Emergence delirium (ED) is common in pediatric anesthesia. This dissociative state in which the patient is confused from their surroundings and flailing can be self-injurious and traumatic for parents.

Partitioning 3-colored complete graphs into three monochromatic cycles [PDF]

open access: yes, 2011
We show in this paper that in every 3-coloring of the edges of Kn all but o(n) of its vertices can be partitioned into three monochromatic cycles. From this, using our earlier results, actually it follows that we can partition all the vertices into at

In ovo green light photostimulation during the late incubation stage affects somatotropic axis activity

open access: yesPoultry Science, 2021
Targeted green light photostimulation during the last stage of broiler incubation increases expression of the somatotropic axis. The purpose of this study was to further shorten the in ovo green light photostimulation and determine the critical age for ...

Neurobehavioural Effects of Monochromatic Light Exposure [PDF]

open access: yes, 2017
Our study is an attempt of partial replication of the study on the effects of monochromatic lights from Sahin and Figueiro (2013). We conducted a two-way crossover comparison between the effects of two Light Emitting Diodes (LED) Monochromatic Lights ...
