2N-storage Runge-Kutta methods: c-reflection symmetry and factorization of the Butcher tableau
Low-storage Runge-Kutta schemes of Williamson's type, so-called 2N-storage schemes, are further examined as a follow-up to the recent work. It is found that the augmented Butcher tableau factorizes into a product of matrices with special properties. Those properties reveal that the 2N-storage methods of the order of global accuracy less than five possess a symmetry, called c-reflection symmetry, i.e. most methods exist in pairs. A transformation that relates the Butcher tableaux of the pairs is…

NIH scientists go public with criticism over Trump cuts
President Donald Trump’s National Institutes of Health director says some employees’ critical letter to him has “fundamental misconceptions about the policy directions the NIH has taken.” Monday’s letter from NIH researchers and staffers says the Republican Trump administration’s policies waste public resources and harm people’s health. NIH Director Jay Bhattacharya in his confirmation hearings pledged openness to views that might conflict with his, saying dissent is the “essenc…

On Monday, scores of scientists at the National Institutes of Health sent their Trump-appointed leader a letter titled the "Bethesda Declaration"
challenging “policies that undermine the NIH mission, waste public resources, and harm the health of Americans and people across the globe.”
It says: “We dissent.”
In a capital where insiders often insist on anonymity to say such things publicly,
92 NIH researchers, program directors, branch chiefs and scientific r…

A Survey of End-to-End Modeling for Distributed DNN Training: Workloads, Simulators, and TCO
Distributed deep neural networks (DNNs) have become a cornerstone for scaling machine learning to meet the demands of increasingly complex applications. However, the rapid growth in model complexity far outpaces CMOS technology scaling, making sustainable and efficient system design a critical challenge. Addressing this requires coordinated co-design across software, hardware, and technology layers. Due to the prohibitive cost and complexity of deploying full-scale training systems, simulators …

Phase shifting Interferometry and Wavefront Compensation using Liquid Crystal on Silicon (LCOS) Spatial Light Modulator (SLM)
We present a simple and novel technique for interferometric surface measurement using a Liquid Crystal on Silicon (LCOS) Spatial Light Modulator (SLM) as phase shifter and wavefront-compensator simultaneously. In comparison to a mechanical piezo-based phase shifter measurement, speed and measurement range can be increased by this approach.
