While attractive force is generated by the goal position, repulsive force is generated by obstacles. The main advantages of APF is its simplicity which only require real time state of environment objects rather than an iterative process as in Dijkstra. The fundamental attractive and repulsive ...
Two types of magnet-related forces can cause injury in a patient with a bio-implant: (a) an attractive transitional force that is proportional to B0, gradient field strength, and the mass, shape and magnetic susceptibility of the object, and (b) the torque that attempts to align or rotate...
It is plausible to assume that the force two objects exert on one another is proportional to their proximity. Preferential attachment networks assume that new edges are formed at a node conditional on the number of existing edges at that node. Wei et al. [61] employ gene-specific prior proba...
Then, we performed a second experiment on adults using the Y-tube two-choice bioassay to test the response ofP. xylostellaadults to heptanal in the presence of the hostBrassica pekinensisleaf (1 × 1 cm2, the oviposition material for adults used in our laboratory) as the attractant in ...
In fact, you will need to gather up everything there is, every last mote (尘埃) of matter, between here and the edge of creation and press it into a spot so infinitesimally compact (紧密的) that it has no dimensions at all. It is known as a singularity.It is natural but wrong to...

While he praises free spirits that “‘give style’ to one’s character” by shaping the self’s multiplicity through the “force of a single taste,” this is not a voluntarist or romantic conception of self-creation. Instead, Nietzsche describes this process as “survey[ing] all the ...

Behind it lies a well-structured treatise designed to account for the force that gods, fate, persuasion, or love can exert upon what we would now call ‘the agent’. Therefore, the many themes mentioned at the beginning of this section (paignion, kairos, pharmakon, etc.) serve as mere ...
124) that is comparable to that of existing cast iron articles of the same size, so that the method according to the invention can be used for the manufacture of a wide range of objects where until now mostly only concrete or cast iron were used, in particular in the construction sector....
