where the sin and cos expressions are the phase and amplitude contrast transfer functions of the objective lens, respectively. The aberration function Δ(Θ, Φ) is given by (11)ΔΘΦ=−14CsΘ4−12Θ2Δf+12ΔzSin2Φ−Φo,where Cs is the spherical aberration coefficient of the obje...
An objective lens drive having an optical axis adjustment function. An objective lens is supported by a lens holder, and the lens holder is supported on a suspension holder by way of a suspension. The suspension holder is supported so as to be rotatable about an axis extending in a ...
(two) according to the motion of the camera is not different, "shooting skills lens: push and pull, shake, move, rise and drop, with. (three) depending on the performance, there are subjective lenses and objective lenses. (four) according to the shooting angle, elevation shooting, flat ...
Surprisingly, native silk, which has been commonly utilized in everyday life as textiles, can be applied as a unique tag material, thereby removing the necessary apparatus for optical physical unclonable functions, such as an objective lens or a coherent light source. Randomly distributed fibers in...
Operating temperature of the video probe -20 °C ~60 °C, below 0 °C should reduce boot operations Waterproof Probes and objective lenses can withstand IP67 waterproof Storage temperature -20°C~60°C Send your message to this supplier *From: *To...
Multiple cues act to position MZ B cells. The cells are attracted to the MZ by sphingosine-1-phosphate receptor-1, which responds to S1P that is abundant in blood6. Although known for their occupancy of the MZ, MZ B cells are motile and continually shuttle between the MZ and follicle7,...

It generates control actions by optimizing an objective function repeatedly over a finite moving prediction horizon and can directly take into account constraints on both process inputs and outputs. Two projection neural networks based on linear and quadratic programming formulations are presented for ...

After the addition of fresh Kreb’s mannitol buffer, the tissue was visualized by acquiring confocal z-stacks (5 µm steps) with a Fluor ×20/0.50 W water dipping objective on an upright ECLIPSE Ni-E Nikon A1 plus system. Two to four z-stacks were taken per mouse, and images ...
