Fractional Partial Differential Equations (FPDEs) are emerging as a powerful tool for modeling challenging multiscale phenomena including overlapping microscopic and macroscopic scales, anomalous transport, and long-range temporal or spatial interactions. The fractional order may be a function of space–time or even be a distribution, opening up tremendous opportunities for modeling and simulati...
I will give a broad overview of what has become the standard paradigm in cosmology. I will describe the relational (à la Leibnitz) notion of time that is often used in cosmological calculations and discuss how the local nature of Einstein’s equations allows us to translate this notion into statements about ‘initial’ data. Classically this relates our local definition of time to a quasi-local re...
The basic properties of a good scintillator material for low and medium energy γ-ray detection are a high and linear light output with energy. In Thallium-doped Cesium Iodine (CsI(Tl)) both requirements are nicely fulfilled. The scintillation is based on two different scintillating states with two significantly different lifetimes of (0.6 and 3.25 μs). It is known, that the ratio of light outpu...

The notion of fractional derivatives, as is long familiar, has its commencement in an inquiry postured amid a correspondence in the middle of Leibnitz and L’hospital. The five millennium extremely ancient inquiry has turned into a significant zone of exploration. As of late, it has been demonstrated that the differential designs including derivatives of fractional order emerge in numerous techn...
Bernardino Ramazzini was born in Carpi near Modina in Italy in 1633. He studied medicine in Parma and took his doctorate in 1659. After a year with Dr Rossi in Rome, he practised for some years in the province of Viterbo until a severe bout of malaria caused him to return to his home town. On recovering he married Francesca Righi. They had a son who died in infancy and two daughters. Carpi serv...
We study a possibility to define the (braided) comultiplication for the GLq(N)covariant differential complexes on some quantum spaces. We discover such differential bialgebras (and Hopf algebras) on the bosonic and fermionic quantum hyperplanes (with additive coproduct) and on the braided matrix algebra BMq(N) with both multiplicative and additive coproducts. The latter case is related (for N =...
The goal of creating non-biological intelligence has been with us for a long time, predating the nominal 1956 establishment of the field of artificial intelligence by centuries or, under some definitions, even by millennia. For much of this history it was reasonable to recast the goal of “creating” intelligence as that of “designing” intelligence. For example, it would have been reasonable in t...
A SCHEME for an artificial language was published in the Philosophical Transactions of the Eoyal Society for 1668 by Bishop Wilkins. Since, however, it presupposes a complete enumeration of all that is or can be known, it would be overthrown by every considerable advance in knowledge. The mathematician and philosopher Leibnitz devoted much thought to what he called a spécieuse générale, which h...
The notion of automata in the sense of machines that operate on their own from encoded instructions is very ancient, and one might say that mechanical clocks and music boxes fall under this category. The idea of computing machines is also very old. For instance. Pascal and Leibnitz outlined various schematics for such machines. In the latter part of the 18th century Baron de Kempelen built what...
