The ultimate goal for singlet fission is that each photo-excited exciton, S1, will result in two triplet excitons with unity yield. However, the now recognized to be complicated, involving bright/dark excited states of different spin multiplicity. Identifying role such vital optimize yield but difficult due their elusive spectral signature. Here, we develop an experimental protocol based on a r...

ibn sina considers the first being in the world to be the first intellect, which issues from the necessary being on the basis of the principle, ‘only one issues from that which is one in all respects’, and through the different aspects of which all other beings come into existence. ibn arabi rejects the basis of ibn sina’s theory of the first emanation, which is the above mentioned principle, a...

in islamic mysticism by annihilation it is meant the removal of any determination, tendency of delimitation to non-delimitation and transformation of multiplicity into unity. the study of historical development of the concept of annihilation can be helpful in understanding and analyzing this fundamental doctrine of mysticism. in early mystical works extant in world of islam, hardly can one find...

UNITY is a simple programming logic to reason about distributed systems. It is especially attractive because of its elegant axiomatical style. Since its power is limited, people introduce variants to extends it with various new functionalities. However, in the axiomatical style it is easy to make a mistake: a seemingly very logical new inference rule may turn out to be unsound. Formal verificat...

This article considers how well the existing sociological literature on immigrant integration and assimilation responds to public fears over multiculturalism. The current backlash against multiculturalism rests on both its perceived negative effects for immigrants’ socioeconomic integration and its failure to encourage civic and political cohesion. I offer a brief review of multiculturalism as ...

We define theta functions attached to indefinite quadratic forms over real number fields and prove that these theta functions are Hilbert modular forms by regarding them as specializations of symplectic theta functions. The eighth root of unity which arises under modular transformations is determined explicitly.
