An alternative computational 'model' for logic programs is proposed which is based upon control annotations written in first-order predicate calculus. These annotations are used to generate runtime environments within which it is possible to exclude infinite computations. The major advantage of such a model is that it is possible to write conceptually transparent programs which otherwise would not have terminated under an existing naive control mechanism.
Recent research has shown the vulnerability of Spiking Neural Networks (SNNs) under adversarial examples that are nearly indistinguishable from clean data in the context of frame-based and event-based information. The...

This paper is concerned with broadcasting on 2-dimensional tonus and mesh networks using circuit-switched, half-duplex, and link-bound communication. It is assumed that there are alpha and beta physical channels in the X- and Y-dimensions, respectively, and path selection between any two nodes is done using row-column routing. Given an n X n mesh or torus, we first discuss the lower bounds of broadcasting time;any broadcasting algorithm requires at least [log((2 alpha+2 beta+1))n(2)] time steps and no broadcasting algorithm achieves this lower bound if alpha < beta(2 beta + 1) We then show that broadcasting on a (2 alpha + 2 beta + 1)(p) X (2 alpha + 2 beta + 1)(p) torus can be done in 2p time steps, which is optimum, for any alpha greater than or equal to 3 and beta = 1. We also present approximation algorithms for the cases of mesh when alpha greater than or equal to 1 and beta = 1 and torus when alpha less than or equal to 2 and beta = 1.

Chip-scale integration of optoelectronic devices such as lasers, waveguides, and modulators on silicon is prevailing as a promising approach to realize future ultrahigh speed optical interconnects. We review recent progress of the direct epitaxy and fabrication of quantum dot （QD） lasers and integrated guided-wave devices on silicon. This approach involves the development of molecular beam epitaxial growth of self- organized QD lasers directly on silicon substrates and their monolithic integration with amorphous silicon waveguides and quantum well electroabsorption modulators. Additionally, we report a preliminary study of long-wavelength （〉 1.3 μm） QD lasers grown on silicon and integrated crystalline silicon waveguides using membrane transfer technology.
We demonstrate efficient on-chip green light generation via frequency upconversion in silicon nitride–thin-film lithium niobate (SiN-TFLN) hybrid waveguides, obtained by transfer printing LN coupons on selected areas...
