To characterize how pollen tubes approached ovules, we limited the angles in this characterization to cos θ mp ≥ 0. We use these statistics to summarize how different incubation times affected the deviation in guidance represented by the Δ θ angle for pollen tubes with tips 0-50 μm and 50-100 μm from a micropyle (Fig. 2D).
Focusing with a 4 π parabolic mirror allows for concentrating light from nearly the complete solid angle, whereas focusing with a single microscope objective limits the angle cone used for focusing to half solid angle at maximum.
Moreover, the diffraction scattering signal at low angle is partially re-absorbed by the resin and the sample itself, therefore limiting the accessible angle range [58].
It was found that the combination of limiting the draping angle and debonding the strands resulted in minimizing the end zone cracking.
Many head-mounted-displays offer a relatively low resolution (images appear pixelated or blurred) and a small field of view limiting the natural angle of view (McMahan, [2012]; Riva, [2003]), creating the impression of looking at a screen instead of feeling immersed in the VE.
As a bonus, the SNO measurements allowed scientists to drastically limit the "mixing angles" that define the neutrinos' flavor-changing abilities, and in December, the KamLAND experiment in Japan restricted the limits even further--with nuclear-reactor-created antineutrinos instead of solar neutrinos.
These included limiting the acceptable range of zenith angles for angle of arrival data and setting limits on acceptable radial velocities.
In contrast, when they struck vertically from a quadrupedal posture, the motion was restricted to relatively protracted angles, limiting the range of motion by roughly half of the full range.
For practical geometries where ( {widehat{n}}_Xcdot widehat{r}<1 ), such as along edges between facets, this limits the contact angle to less than half the internal angle.
A two-stage control procedure is developed to design a simple and effective tension control law that is capable of limiting the magnitude of libration angle and suppressing the tension disturbance in the tether deployment process.
