The singular values of a product M independent Ginibre matrices size N×N form determinantal point process. Near the soft edge, as both and N go to infinity in such way that M/N→α, α>0, scaling limit emerges. We consider gap probability for corresponding limiting process, namely, there are no particles interval (a,+∞). derive Tracy–Widom-like formula terms unique solution certain matrix Riemann–...

Silica based glasses are used as nuclear shielding materials. The effect of radiation on these glasses varies as per the constituents used in these glasses. Glasses of different composition of SiO2-Na2OMgO-Al2O3 were made by melt casting techniques. These glasses were irradiated with neutrons of different fluences. Optical absorption measurements of neutron-irradiated silica based glasses were ...

Suppression of gap-junctional communication by various protein kinases, growth factors, and oncogenes frequently correlates with enhanced mitogenesis. The oncogene v-src appears to cause acute closure of gap junction channels. Tyr265 in the COOH-terminal tail of connexin 43 (Cx43) has been implicated as a potential target of v-src, although v-src action has also been associated with changes in ...

In contrast to the knowledge of chemical synapses, little is known regarding the properties of gap junction-mediated electrical synapses in developing zebrafish, which provide a valuable model to study neural function at the systems level. Identifiable "mixed" (electrical and chemical) auditory synaptic contacts known as "club endings" on Mauthner cells (2 large reticulospinal neurons involved ...

Let (Xi)i∈N be a sequence of independent and identically distributed random variables with values in the set N0 of non-negative integers. Motivated by applications in enumerative combinatorics and analysis of algorithms we investigate the number of gaps and the length of the longest gap in the set {X1, . . . , Xn} of the first n values. We obtain necessary and sufficient conditions in terms of ...

While the discourse of international development has begun to recognise the potential of involving diaspora as agents of change, issues of sustainability and environmental impact are often missing from the assessment of outcomes and impact in the Global South. The purpose of the conference was to explore three terms: “development”, “sustainability” and “diaspora” which are often seen as separat...

The present contribution tests whether countries can be pooled when studying the financegrowth nexus. Overall, our results point toward a ‘pragmatic’ positive answer, though considerable heterogeneity is present among developing countries. JEL codes: C23, O16

T his year’s World Water Day focused on the food-water nexus with the theme “Water and Food Security: The World is Thirsty Because We are Hungry.” While much of the emphasis under this theme focused on the quantities of water used for food produc­ tion, the quality of water is also important to that function. Water quality can also have sig­ nificant effects on health. In this context, the qual...
