Petrological, fauna] and floral infomiation derived from a new drill core taken in the Yangtze delta, coupled with data from borings recovered earlier, record a marked transition to wanner, wetter conditions which resulted in widespread inundation of the delta about 4000 years ago. Also identified for that time on the delta plain is a m;\jor discontinuity between the Neolithic Liangzhu and Bron...

Operator-splitting approaches are often used for plasma 3-T radiation diffusion equations, since many linear solvers could not effectively solve the coupled linear system resulted from plasma 3-T radiation diffusion equations. An approach of operator-splitting is proposed for numerically solving plasma 3-T radiation diffusion equations. To resolve sub-cell structure in mixed cells, interface re...

Single crystal and powder samples of [Co(terpy)(2)][BF(4)](2) are low spin below 100 K but show a typically gradual thermal spin-transition on warming, centred near 270 K. However, the spin-crossover exhibits an unusual and pronounced discontinuity above room temperature, when the material is ca. 87% high-spin. A crystallographic study at nine temperatures between 30-375 K showed that the disco...

Theories about the evolution of consciousness relate in an intimate way to theories about the distribution of consciousness, which range from the view that only human beings are conscious to the view that all matter is in some sense conscious. Broadly speaking, such theories can be classified into discontinuity theories and continuity theories. Discontinuity theories propose that consciousness ...

Distributive lattices with operators (DLO) are a natural generalization of the notion of Boolean algebras with operators. An operator in a bounded distributive lattice A is a function f : An → A which preserves ∧ (or ∨) in each coordinate. In the last few years these classes of algebras have been actively investigated since they appear as algebraic counterpart of many logics. Some important con...

While handling deformable linear objects (DLOs), such as hoses, wires or leaf springs, with an industrial robot at high speed, unintended and undesired oscillations that delay further operations may occur. This paper analyzes oscillations based on a simple model with one degree of freedom (DOF) and presents a method for active open-loop damping. Different ways to interpret an oscillating DLO as...

Earth’s mantle transition zone (MTZ) is characterized by several sharp increases in seismic wave speed between ~300 km and ~850 depth. These discontinuities are generally attributed to solid-state phase transitions that lead density viscosity increases, which could cause a barrier convection segregating thermally chemically heterogeneous material. This Review discusses insights into the role of...
