SUMMARY:Rishav Roshan: Gravitational wave production during reheating: From the inflaton to primordial black holes
DESCRIPTION:We calculate the gravitational waves (GWs) produced by primordial black holes (PBHs) in the presence of the inflaton condensate in the early Universe. Combining the GW production from the evaporation process\, the gravitational scattering of the inflaton itself\, and the density fluctuations due to the inhomogeneous distribution of PBHs\, we propose for the first time a complete\, coherent analysis of the spectrum\, revealing three peaks\, one for each source. Three frequency ranges (~kHz\, GHz\, and PHz\, respectively) are expected\, each giving rise to a similar GW peak amplitude Ω_GW. We also compare our predictions with current and future GW detection experiments.\nhttps://indico.ijs.si/event/3730/

SUMMARY:Andraž Stožer & Marko Gosak\, "From Ca²⁺ Waves to Insulin Pulses: Experimental and Theoretical Perspectives on β-Cell Network Dynamics"
DESCRIPTION:Pancreatic β-cells within the islets of Langerhans coordinate their activity to generate pulsatile insulin secretion\, a process essential for glucose homeostasis and disrupted during the development of diabetes. This seminar will combine experimental physiology and mathematical modelling to examine how multicellular β-cell networks encode\, propagate\, and translate Ca²⁺ signals into insulin release. In the experimental part\, we will present insights from high-frequency confocal Ca²⁺ imaging\, showing how β-cells respond heterogeneously to stimulation\, how fast Ca²⁺ oscillations and intercellular waves emerge within islets\, and how specific cellular subpopulations may contribute to signal initiation and propagation. We will also discuss conserved and altered features of these dynamics in human islets and during diabetes progression. Building on these findings\, the modelling part will address why mathematical abstraction is needed to disentangle the mechanisms underlying such complex multiscale behaviour. We will present a phenomenological multicellular model that links structural gap-junction coupling\, timescale-specific functional connectivity\, and secretion. The model reproduces experimentally observed slow metabolic oscillations\, fast bursts\, and ultrafast spikes\, and shows how interactions between these temporal domains shape pulsatile insulin output. By integrating high-resolution Ca²⁺ imaging with phenomenological modelling\, the seminar highlights how interdisciplinary approaches can reveal the principles governing β-cell network function and its disruption in diabetes.\nhttps://indico.ijs.si/event/3643/
