We are very sad to announce that Jeff Cash, Emeritus Professor at Imperial College in London, passed away on June 19th. Jeff received his Mathematics degree from Imperial College, London, in 1969 and then moved to St. John's College, Cambridge, where he studied for a PhD on the numerical solution of differential equations under the guidance of Dr. J.C.P. Miller. Having completed his studies in Cambridge, Jeff returned to Imperial College as a member of staff in the Mathematics Department. He was subsequently promoted to reader and then to Professor in Numerical Analysis. Jeff's research has been mainly focused on the solution of difference and differential equations, with an emphasis on mathematical software. In this field, he made substantial contributions, among which are innovative numerical methods and codes that have proven to be of great importance. Jeff will stay in our memory as a cordial, generous, and upright person. Yet, when living memory of him passes, the methods he created will continue to serve us all. ------------------------------------------------------- From: Marion Weinzierl [log in to unmask] Date: June 26, 2020 Subject: International Series of Online Research Software Events The international Series of Online Research Software Events (SORSE) has opened their call for contributions: https://sorse.github.io/programme/call-for-contributions/ With the cancellation of several international Research Software Engineering (RSE) community events as a result of the COVID-19 pandemic, RSEs worldwide are facing a lack of opportunities to engage with their wider community. To address this challenge, SORSE has been launched by an international committee to provide an opportunity for RSEs to develop and grow their skills, build new collaborations and engage with RSEs worldwide. Until we can meet again in person, SORSE (pronounced "Source"), will bridge the gap and be the source of interesting and engaging events. This is an open call to all RSEs and anyone involved with research software, worldwide, to propose talks, workshops and other types of online events. The Call for Contributions form will remain open continuously and there will be a rolling deadline at the end of the last day (UTC) of each month, following which all contributions received over the previous month will be sent for review by the Programme Committee. ------------------------------------------------------- From: Harbir Antil [log in to unmask] Date: June 28, 2020 Subject: CMAI Colloquium Under the newly created Center for Mathematics and Artificial Intelligence (CMAI) http://cmai.gmu.edu/ at George Mason University, Fairfax, VA, we are currently running a virtual Colloquium Series https://cmai.gmu.edu/index.php/events/#colloquium .
