We present Space-Time Correspondence Networks (STCN) as the new, effective, and efficient framework to model space-time correspondences in the context of video object segmentation. STCN achieves SOTA results on multiple benchmarks while running fast at 20+ FPS without bells and whistles. Its spe...
We then calculate predicted tie probabilities for each network, using both its own parameter estimates and the estimates from every other network in the collection. Comparison is based on the similarity between sets of predicted tie probabilities. We then use correspondence analysis to represent the ...
To test the effects of delayed epidemic starting dates, we build up a synthetic scenario where the Covid-19 outbreak spreads independently in each Region (see “Methods” for the estimation of the experimental time delays and for the Regional\(SIOR\)model); as argued before, given the Italian...
CorrespondenceLatticeModelsofGravityExisting tensor network models of holography are limited to representing the geometry of constant time slices of static spacetimes. We study the possibility of describing the geometry of a dynamic spacetime using tensor networks. We find it is necessary to give a ...
Space, time, and number are among fundamental aspects of behavior and reasoning about the environment. Recent studies have shown that these dimensions high

A new concept of a space-based synchronized reference network is proposed with the development of an optical frequency reference and laser inter-satellite link. To build such time reference, three clock ensemble algorithms, namely the natural Kalman timescale (NKT) algorithm, the reduced Kalman time...
In this research, a reliable coding scheme is introduced, namely inter-multilevel super-orthogonal space–time coding (IM-SOSTC), which allows for inter-level dependency between adjacent multilevel coded blocks to improve coding gain and guarantee full diversity whilst maintaining reasonable spectral ...
1a. Optical pulses that overlap in time and travel in free space at a group velocity \(\widetilde{v}=c\) are transformed into ST wave packets having different group velocities \({\widetilde{v}}_{1}\) and \({\widetilde{v}}_{2}\) via spatio-temporal spectral phase modulations ...
The perceptual grouping allows to decrease the search space for the 2D to 3D correspondence problem, lowering the amount of PnP problems to solve and the computational time as a consequence. The perceptual grouping process is applied also to the 3D wireframe model available. Such process is ...
