Abstract We introduce the theory of the analytic de Rham stack and the Hyodo Kato stacks. We then sketch the main ideas behind a new interpretation and proof of the local p-adic monodromy …

Abstract Nucleophilic substitution on an sp³ carbon center is one of the most fundamental and widely used transformations in organic chemistry. While the stereochemical outcome of a SN2 reaction is well known - it takes place with configuration …

Abstract The good health of living organisms, both human and non-human, is first and foremost a synthesis of the environmental conditions to which they are exposed. However, many health threats are looming on the horizon : accelerated transmission of …

Abstract This session explores the question of revolution, going beyond a strictly political reading to consider its cultural and intellectual dimensions. Revolution is seen here not just as an upheaval of legal or institutional structures, but as a more …

Non-relativistic limits of the light cone: "vertical" straight line (c → 0) or "horizontal" hyperplane (c → ∞) Presentation The non-relativistic limits of Einstein's theory - also known as non-Lorentzian limits - are obtained by tending the speed of …

Résumé Ardashīr I, in the third century claimed to be the king of the Iranians, and by the time of Shapur I the realm was known as Ērānšahr , i.e., the “Empire of the Iranians.” During the Sasanian period, not only the idea of Iran took form, but its …

Abstract Activation of carbene precursors by planar, low-spin cobalt(II) complexes leads to formation of 'carbene radical' intermediates. 1 These are intrinsically reactive metal-bound carbon radicals (Figure 1), useful for catalytic synthesis of a …

Abstract Polyoxometalates (POMs) form a versatile family of molecular oxide clusters of the early transition metals endowed with exceptional redox properties, which have driven applications in photo/electro-catalysis, photo/electro-chromic materials, …

Abstract Activation of small molecules by donor-acceptor systems is conceptually important as many catalytic processes rely on the synergistic action of electron-rich and -poor sites to cooperatively activate and cleave bonds. This pertains to both the …

Abstract IUPAC defines a "mechano-chemical reaction" as a "chemical reaction that is induced by the direct absorption of mechanical energy". 1 We investigated a wide range of organic reactions and found that ball milling can affect the oxidation states of …
