Narayanaswamy Balakrishnan (Bala): Accelerated Life Testing of One-Shot Devices: Data Collection and Analysis

1:00pm, ZOOM

In this talk, I will introduce the problem of evaluation of reliability of one-shot devices. After providing some practical data sets on different types of tests involving one-shot devices, I will describe various estimation methods under classical setup and also in the framework of accelerated life-testing conditions. I shall also elaborate on model validation and model selection methods. Finally, I shall discuss the problem of optimal design under testing budget constraints. Throughout, I shall use different data sets to illustrate the methods developed.

Theresa Abl: Towards the Virasoro-Shapiro amplitude in AdS5xS5

3:00pm, Zoom (Meeting ID: 931 4876 1099 Passcode: 685500)

In flat space, four-point amplitudes of closed strings in type IIB string theory are described by the Virasoro-Shapiro amplitude. It is of great interest to generalise this to curved backgrounds and in this talk we focus on string theory in AdS5xS5, which is dual to N=4 SYM. We introduce a simple 10d scalar effective field theory describing the stringy corrections to supergravity in AdS5xS5 from which we can systematically derive all four-point 1/2-BPS correlators described by tree-level string theory. To do this we introduce a new 10d formulation of Witten diagrams and the Mellin transform which treats AdS and S on equal footing.
