is equally expressive to the variant with parametric definitions. (2) The CCS variant with replication is equally expressive to that with recursive expressions and static scoping.  ...  From (1) and the well-known fact that parametric definitions can replace injective relabelings, we show that injective relabelings are redundant (i.e., derived) in CCS (which has constant definitions only  ...  We are indebted to Maurizio Gabbrielli, Jean-Jacques Lévy, Sergio Maffeis, Catuscia Palamidessi, Joachim Parrow, Rosario Pugliese and Davide Sangiorgi, for insightful discussions on the topics of this  ...

Parametric channels via label expressions in CCS

Egidio Astesiano, Elena Zucca
1984 Theoretical Computer Science  
Nevertheless, as it stands, it suffe*s from a limitation: it is impossible to determine at run time the channel on which to send or receive a communication.  ...  There are various possibihties for giving CCS such ability, but the price can be a drastic change in the language and the thzoq of ccs.  ...  Acknowledgment We are grateful to all the referees, both of the Conference paper and of the present one, for their careful comments, which have been of great help in making the presentation more readable  ...

Neutrino mass ordering and μ-τ reflection symmetry breaking

Zhi-zhong Xing, Jing-yu Zhu
2017 Chinese Physics C, High Energy Physics & Nuclear Physics  
If the neutrino mass spectrum turns out to be m^_3 < m^_1 < m^_2, one may choose to relabel it as m^'_1 < m^'_2 < m^'_3 such that all the masses of fundamental fermions with the same electrical charges  ...  In this case the columns of the 3× 3 lepton flavor mixing matrix U should be reordered accordingly, and the resulting pattern U^' may involve one or two large mixing angles in the standard parametrization  ...  conflict with previous studies based on very preliminary neutrino oscillation data [26] .  ...

Non-interleaving semantics for mobile processes

Pierpaolo Degano, Corrado Priami
1999 Theoretical Computer Science  
The presentation takes advantage of a parametric definition of process behaviour given in SOS style that permits us to take almost for free the interleaving theory and tools.  ...  Finally, we extend our approach to higherorder n-calculus, enriched with a spurn operation.  ...  The next one shows that [7,0c coincides with the relation introduced in [5] for pure CCS that has no value or name passing. . .

There- fore the author considers C‘, the largest relation included in C which is a precongruence relation with respect to all the operators of CCS.  ...  This relation, which is properly contained in the previous one, is preserved by the com- position, restriction, and relabelling operators, but not by prefixing and summation.  ...

Programming with behaviors in an ML framework — The syntax and semantics of LCS [chapter]

Bernard Berthomieu, Thierry Sergent
1994 Lecture Notes in Computer Science  
LCS settled for a more conservative approach based on parametric channels as introduced in [1]; this permits to retain most of the underlying theory of CCS.  ...  The language extends Standard ML with primitives for concurrency and communication based upon a higher order extension of the CCS formalism. Typechecking enforces consistency of communications.  ...  Acknowledgments Didier Giraltt and Jean-Paul Gouyon worked intensively on the project in its early stages.  ...

Contextual Imagined Goals for Self-Supervised Robotic Learning [article]

Ashvin Nair, Shikhar Bahl, Alexander Khazatsky, Vitchyr Pong, Glen Berseth, Sergey Levine
2019 arXiv   pre-print
When the robot's environment and available objects vary, as they do in most open-world settings, the robot must propose to itself only those goals that it can accomplish in its present setting with the  ...  We demonstrate that this enables self-supervised goal-conditioned off-policy learning with raw image observations in the real world, enabling a robot to manipulate a variety of objects and generalize to  ...  It is trained by reconstructing states s with a parametrized encoder that converts the state into a normal random distribution q φ (z|s) with a parametrized decoder that converts the latent variable z  ...

2005 Lecture Notes in Computer Science  
Its results are more stable than the Witelson subdivision scheme or other commonly applied schemes based on the CC bounding box.  ...  The probabilistic subdivision is based on the distances of arc-length parameterized corpus callosum contour points to trans-callosal DTI fibers associated with an automatic lobe subdivision.  ...  Correspondence via Fourier Descriptors (arc-length parametrization): The segmentation procedure yields Fourier coefficients with an inherent correspondence based on its arc-length parametrization.  ...
