PURPOSE: A vertical control method is provided, which makes light reach a recognition unit only when two planes are perpendicular with each other. CONSTITUTION: A vertical control method is as follows. In a first plane, light source(140) is set up in parallel with the first plane. In a ...

Orthogonally twisted CrSBr ferromagnetic monolayers with in-plane Ising anisotropies are found to exhibit multistep magnetoresistance switching with a magnetic hysteresis opening. This work emphasizes the role of spin dimensionality in two-dimensional magnets, and the potential of orthogonal and large-twist...
possible. The profile of its liquidus shows a minimum and thus mirrors the refractoriness of aluminosilicate refractories (Figure 3.24). Refractoriness, the prime requirement of a refractory, is commonly determined by an empirical laboratory test. A sample cone of a given refractory is placed on a...
A) a device for removably connecting two sections perpendicular to the spacer in a plane perpendicular to one another; & lt; br / > b), characterized in that the support is a fastening member (30) which is wedged in a removable manner in the longitudinal groove (11) of the first secti...
Introducing the Fresnel reflection coefficients \({r}_{\perp ,\parallel }(\alpha )\), for the reflected fields perpendicular and parallel to the scattering plane respectively54, the expression at the lens L4 in the reference arm becomes $${\overrightarrow{E}}_{5}=\sqrt{\frac{{f}_{2}...
The imposed temperature gradient is uniform and perpendicular to the plane walls. The Knudsen number is assumed to be small so that the fluid flow is described by a continuum model with a temperature jump, a thermal slip, and a frictional slip at the particle surface. The presence of the ...
within each molecule layer of dC10Cl, the nitrogen atoms (N+) locate at the center of (CH3–(CH2)9)2NH2+and chlorine atoms (Cl-) are spread inabplane, as shown in Fig.1c, while (CH3–(CH2)9) chains, parallel to each other, are extended along the direction nearly perpendicular to...
In our design,dm–cis constant during imaging because the mirror holder is supported independently of the objective (Fig.1d). Therefore, when the focal plane is deepened, the distance between the objective exit and upper surface of the mirrors (do–m) is shortened. This decreases the amount ...
