Abstract: Physics-informed neural networks (PINNs) are a new and promising methodology to combine deep learning with partial differential equations (PDE). PINNs extend deep neural networks by regularizing their output to fulfill any given PDE, allowing to solve both forward and inverse PDE problems utilizing high-performance machine learning libraries such as Tensorflow and PyTorch. This talk will give a short introduction to PINNs and provide a detailed, tutorial-style code demonstration on their implementation in PyTorch.

This talk is part of the Mechanics Lunch Seminar series. That means 20min talks plus discussion in an informal setting.

Abstract: Intraluminal vesicle (ILV) formation plays a crucial role in the attenuation of growth factor receptor signaling. The endosomal sorting complex required for transport (ESCRT-0 to -III/VPS4) mediates this process. The general dogma has been that upstream ESCRTs (0 to II) sequester receptors at the surface of endosomes and the downstream ESCRTs (III/VPS4) remodel the endosome membrane leading to the abscission and formation of receptor-containing ILVs. We now show that upstream ESCRTs not only sequester cargo, but in addition play a crucial role for the initiation of membrane shape remodeling in ILV budding. Through a combination of mathematical modeling and experimental measurements we show that upstream ESCRTs facilitate ILV budding by crowding with a high density in the membrane neck region.

C*-algebra seminar talk by Mario Klisse (Delft)

Carla Janaina Ferreira (DNV GL) will give a talk on November 24th at 14:15 (held with restricted attendance in the Erling Sverdrups plass, Niels Henrik Abels hus, 8th floor and streamed in Zoom - the link will be sent by mail one day in advance).

A large conference in the beautiful Hammamet, along the shores of the blue Mediterranean, was announced to take place at the end of November. Unfortunately, the Corona pandemia got in the way and we shall all hedge the risk. The conference in postponed. For now, we shall have chance to meet virtually by Zoom and enjoy an appetiser of stochastics to keep us fit for the larger event.

The 2-days webinar on November 23-24 from 9:15 to 13:00

Doctoral candidate Martin Helsø at the Department of Mathematic, Faculty of Mathematics and Natural Sciences, is  defending the thesis Investigations into real determinantal quartic hypersurfaces for the degree of Philosophiae Doctor.

Abstract: Due to the fluid nature of biological membranes, proteins are able to diffuse along the membrane surface. Additionally, several processes of vesicle formation require protein recruitment.  We discuss, on one hand, the implications of fixed membrane shapes in protein diffusion, and on the other hand, the effects of protein diffusion and recruitment in membrane shape transformation.
