Substrate scope of ancestral versus modern family‐1 glycosidases

Protein Science, Volume 35, Issue 7, July 2026.
Abstract Experimental studies support that protein engineering based on ancestral sequence reconstruction often leads to variants with biotechnologically useful biomolecular properties. These may include high stability, enhanced conformational flexibility and a modified catalysis range.

Rethinking Per‐Thread Computation for Machine Learning Design Exploration: A Work‐Efficient GPU Strategy for K‐Means and XGBoost

Concurrency and Computation: Practice and Experience, Volume 38, Issue 11, June 2026.
ABSTRACT This paper presents novel GPU implementation strategies that effectively exploit the available parallelism, based on the “more work per thread” approach, for three machine learning design exploration tasks: Multiple K‐means evaluation, dimensionality reduction through parallel K‐means encoding for XGBoost trees, and XGBoost tree pruning ...

Autonomous Navigation in Large‐Scale Underground Environments Based on a Purely Topological Understanding of Tunnel Networks

Journal of Field Robotics, Volume 43, Issue 4, Page 2671-2692, June 2026.
ABSTRACT This work presents a non‐geometrical navigation approach based on a purely topological understanding of underground environments. By conceptualizing subterranean scenarios as a set of tunnels that intersect with each other, and taking a navigation approach based on topological instructions, we simplify the navigation problem to the sequential ...

Factors to Foster Resilience Against Coding Stressors of Agile Software Developers

Journal of Software: Evolution and Process, Volume 38, Issue 6, June 2026.
ABSTRACT IT workers, especially software developers, undergo high stress levels due to their intellectual activity, which requires creativity and problem‐solving skills for specific situations. These circumstances often lead to a fast‐paced lifestyle, including sleep deprivation, which is often worn as a badge of honor.

Physicians' hybridisation with accounting in public hospitals

Accounting &Finance, Volume 66, Issue 2, Page 2061-2083, June 2026.
Abstract Accounting information has become an integral part of management tools in public hospitals. Following COVID‐19, the crisis in the supply chain and the war in Ukraine severely impacted the financing of public hospitals. In response to this multi‐crisis environment, physicians have increased their awareness on an efficient use of scarce ...

The Power of Professional Expertise: Unravelling the Boardroom Diversity Puzzle Through a Machine Learning Approach

Accounting &Finance, Volume 66, Issue 2, Page 1571-1593, June 2026.
ABSTRACT This study examines how board expertise diversity influences firm performance using a novel machine learning approach to classify directors' professional backgrounds. Drawing on data from Spanish listed firms, we develop multidimensional expertise profiles that capture multiple skills held by each director.
