Diameters of duals are linear
For every oriented tree T there exists a graph DT (called the dual of T ) such that T 6→ G ⇔ G → DT holds for every G (an arrow denotes the existence of a homomorphism). An explicit construction of DT has been found recently. Although the DT constructed this way may have exponential number of vertices in |V (T )| = n, we will prove that its diameter is linear in n (and therefore DT is ”small” i...
متن کاملElastic effects of liquids on surface physics
The contact between a liquid and an elastic solid generates a stress vector depending on the curvature tensor in each point of the separating surface. For nanometer values of the mean curvature and for suitable materials, the stress vector takes significant amplitude on the surface. Although the surface average action of the liquid on the solid is the hydrostatic pressure, the local strain gene...
متن کاملWhy liquids are fragile.
The fragilities (T(g)-normalized temperature dependence of alpha-relaxation times) of 33 glass-forming liquids and polymers are compared for isobaric, mP, and isochoric, mV, conditions. We find that the two quantities are linearly correlated: mP = (37+/-3) + (0.84+/-0.05)mV. This result has obvious and important consequences, since the ratio mV/mP is a measure of the relative degree to which te...
متن کاملAre dipolar liquids ferroelectric?
VH and HV depolarized hyper-Rayleigh scattering spectra were measured for liquid solutions of dipolar CH3CN in nondipolar C2Cl4 at T=300 K. The VH spectrum contains a strong narrow peak due to a slowly relaxing longitudinal orientation mode. This peak is absent in the HV spectrum, and it disappears from the VH spectrum when the CH3CN concentration is reduced to 8%. This observation is consisten...
متن کاملRectilinear Paths among Rectilinear Obstacles
Given a set of obstacles and two distinguished points in the plane the problem of nding a collision free path subject to a certain optimization function is a fundamental problem that arises in many elds, such as motion planning in robotics, wire routing in VLSI and logistics in operations research. In this survey we emphasize its applications to VLSI design and limit ourselves to the rectilinea...
