We discuss the implications of an experiment in which the frequencies of two laser beams are compared for different intensities in order to search for a dependence of the frequency of light on its intensity. Since no such dependence was found it is possible to place bounds on a description of...
An analysis of the light curves of R CrB for 130 years and of RY Sgr and SU Tau for 90 years is presented. It is shown that the time intervals between the consecutive minima of the visual brightness of R Coronae Borealis type stars are distributed uniformly with upper limits of 1540 d...
The article presents the results of the analysis of 20 of the most popular surnames on the current German territory. The research has used amongst others data from the Vervandt (www.verwandt.de) internet service. It has been estimated that 4,06% of German population has Polish surnames, wh...

Coherent frequency conversion of structured light, i.e. the ability to manipulate the carrier frequency of a wave front without distorting its spatial phase and intensity profile, provides the opportunity for numerous novel applications in photonic technology and fundamental science. In particular, freque...
The SA firstly guides the model to search and focus on buildings, and HF is employed afterwards to highlight the high frequency information of the input feature maps. With high frequency information of buildings enhanced by HFAB, HFA-Net is able to better detect the edges of changed buildings...

We have measured the frequency of methane-stabilized laser at 88 THz (3.39 µm) (ref. 1), by method which largely eliminates the uncertainties contributed by lower-frequency lasers used as transfer oscillators. This result is primarily of interest for
The effect of light/dark (L:D) cycle times on the recovery from photoinhibition of green micro-alga Chlorella vulgaris (CCAP211/11c) and the cyanobacterium Synechococcus (CCAP1479/5) was investigated using an irradiated, temperature controlled oxygen electrode. The onset of photoinhibition in both ...
In the present work, fiber-based frequency-modulated light scattering interferometry (FMLSI) is developed and employed for studies of optical properties and dynamics in liquid phantoms made from Intralipid. The fiber-based FMLSI system retrieves the optical properties by examining the intensity fluctuat...
