Nuclear many-body theory has been intensively studied for many years and reached a high level of understanding, but there still are some unresolved fundamental problems. One of the leading approaches is to introduce an effective interaction and reduce the full many-body problem to a certain model-space problem. There have been many review works concerning the effective interaction theory, for e...

The relationship of scientific knowledge development to technological development is widely recognized as one of the most important and complex aspects of technological evolution. This paper adds to our understanding of the relationship through use of a more rigorous structure for differentiating among technologies based upon technological domains (defined as consisting of the artifacts over ti...

This paper deals with the problem of estimating an appropriate hand posture to grasp an object, from 2D object’s visual cues in a many-to-many (objects,grasp) configuration. A statistical learning protocol implementing vector-valued regression is adopted for both classifying the most likely grasp type and estimating the hand posture. An extensive experimental evaluation on a publicly available ...

We show that the full version of the so-called ‘rural hospital theorem’ generalizes to many-to-many matching problems where agents on both sides of the problem have substitutable and weakly separable preferences. We also show that when agents’ preferences satisfy substitutability, the domain of weakly separable pref-

In this note, I extend the work of Echenique (forthcoming) to show that a model of many-to-many matching with contracts may be embedded into a model of many-tomany matching with wage bargaining whenever (1) all agents’ preferences are substitutable and (2) the matching with contracts model is unitary, in the sense that every contractual relationship between a given firm–worker pair is specified...

instrumentalism (in the science) refers to a view that considers scientific theories as nothing more than instruments for prediction. sometimes the traces of this attitude have been searched in the writings of plato and aristotle; but mostly the pioneers of the theory have been thought to be the priests who regarded the scientific propositions as mere hypothesis, in order to defend religious do...
