today, i rode a bike from the Camberville E-Bike Library to the Roslindale library; picked up a trike from there to take to our maintenance partner (NEMO), picked up a bike from NEMO and went to the office, left the office to come back to NEMO, went from NEMO to the Rozzie E-Bike Library again, then took a bluebike e-bike back from Rozzie to Somerville.
This is what it looks like to be your own inter-library loan program.

Tribes Meeting With Inter-American Commission on Human Rights Describe Harms Uranium Mining Has Had on Them, and the Threats New Mines Pose - Inside Climate News
As spiking uranium prices drive a surge of proposals for new mines, the Navajo Nation joined the Ute Mountain Ute, Havasupai, Northern Arapaho and Oglala Sioux tribes in a commission hearing with federal officials to push back against mining on and near their lands.

A higher-order transformation approach to the formalization and analysis of BPMN using graph transformation systems
The Business Process Modeling Notation (BPMN) is a widely used standard notation for defining intra- and inter-organizational workflows. However, the informal description of the BPMN execution semantics leads to different interpretations of BPMN elements and difficulties in checking behavioral properties. In this article, we propose a formalization of the execution semantics of BPMN that, compared to existing approaches, covers more BPMN elements while also facilitating property checking. Our a…

Scheduling for On-Board Federated Learning with Satellite Clusters
Mega-constellations of small satellites have evolved into a source of massive amount of valuable data. To manage this data efficiently, on-board federated learning (FL) enables satellites to train a machine learning (ML) model collaboratively without having to share the raw data. This paper introduces a scheme for scheduling on-board FL for constellations connected with intra-orbit inter-satellite links. The proposed scheme utilizes the predictable visibility pattern between satellites and grou…

Inter-laboratory replicability and sensitivity study of a finite element model to quantify human femur failure load: case of metastases
Metastases increase the risk of fracture when affecting the femur. Consequently, clinicians need to know if the patients femur can withstand the stress of daily activities. The current tools used in clinics are not sufficiently precise. A new method, the CT-scan-based finite element analysis, gives good predictive results. However, none of the existing models were tested for reproducibility. This is a critical issue to address in order to apply the technique on a large cohort around the world t…

Code Generation and Performance Engineering for Matrix-Free Finite Element Methods on Hybrid Tetrahedral Grids
This paper introduces a code generator designed for node-level optimized, extreme-scalable, matrix-free finite element operators on hybrid tetrahedral grids. It optimizes the local evaluation of bilinear forms through various techniques including tabulation, relocation of loop invariants, and inter-element vectorization - implemented as transformations of an abstract syntax tree. A key contribution is the development, analysis, and generation of efficient loop patterns that leverage the local s…
