Subject: Software Announcement: GRASP — Solver Reliability Analysis and Validation Framework
GRASP is a framework for analysing the global reliability of nonlinear
root-finding methods.
Unlike standard numerical libraries (e.g., MATLAB, SciPy,
Mathematica), which typically evaluate solvers from a single initial
condition, GRASP studies solver behaviour across large sets of initial
conditions. The goal is to better understand convergence reliability,
failure regions, and basin-of-attraction structure.
The framework provides:
- large-scale sweeps of initial conditions
- statistical reliability estimates (success probability, coverage)
- basin-of-attraction diagnostics
- automated interpretation of solver behaviour
- a validation layer that checks consistency between expected and
observed outcomes
In particular, GRASP attempts to bridge the gap between theoretical
expectations (e.g., derivative-related pathologies) and observed
numerical behaviour by explicitly validating solver performance.
A live demo is available here:

I would be grateful for any feedback from the community.

Subject: Mimetics Operators Library Enhance (MOLE) Tutorial, May 12, 2026
The Computation Science Research Center (CSRC) at San Diego State
University invites you to: A Tutorial on The Mimetic Operators
Library Enhanced (MOLE) May 12, 2026 from 10 AM to 12:00 PM. PDT.
MOLE is a high-quality numerical library that implements high-order
mimetic difference operators to solve PDEs in C++ and MATLAB/Octave.
It provides discrete analogs of the most common vector calculus
operators: Gradient, Divergence, Laplacian, and Curl. These operators
(highly sparse matrices) act on staggered grids (uniform, non-uniform,
curvilinear) and preserve locally and globally quantities of interests
for systems of conservation laws.
This tutorial will cover an introduction to MOLE mimetic difference
operators; gradient, divergence, laplacian and curl for C++ and MATLAB
/Octave users. Attendants will learn how to use the MOLE library
through examples, and also review the installation and guidelines to
contribute to the MOLE library. Please, read the Getting Started
Section in mole-docs.readthedocs.io/ and install or clone the MOLE
library. Installation support will be provided 90-minutes prior to
the beginning of the tutorial.
The tutorial is free and will be held in person at SDSU’s Bioscience
Center Auditorium on May 12, 2026 from 10 AM to 12:00 PM U.S. PT, and
also online. To register for the tutorial in person or online, please
fill out this form: https://forms.gle/7KZ8t3zCUxu7f6vB7.

Subject: PhD scholarship in Karlsruhe: Estimation of short-term extremes in air pollution and their drivers, Germany (DAAD scholarship)
We are currently looking for a PhD candidate for a research project on
“Estimation of short term extremes in air pollution and their drivers”
supervised by Hendrik Andersen, Jan Cermak and Vicky Fasen-Hartmann at
KIT Graduate School Computational and Data Science (KCDS), Karlsruhe
Institute of Technology (KIT).
The research focus is on developing a new data-driven approach to
accurately predict extremes in urban air pollution from observation
data, and to quantify the contributions of the various factors driving
these extremes. Therefore, methods from extreme value statistics will
be implemented in a machine-learning framework to estimate and predict
air pollution extremes. As a starting point, we use Paris as a
baseline city, where ML methods were successfully implemented to
reproduce specified PM1 concentrations. This model architecture will
be adapted and retrained on multi-city data from global air pollution
hotspots, enabling generalization beyond the urban area of Paris.
The project lies at the intersection of innovation in mathematics and
meteorology. By combining extreme value theory with machine learning,
it aims to advance the current state of the art in predicting air
pollution extremes.
The doctoral degree will be awarded in either Mathematics or
Meteorology, depending on the candidate’s academic background.
The successful candidate will receive a DAAD Graduate School
Scholarship funded by the German Academic Exchange Service (DAAD).
