Speed reduction in aviation: A double dividend for decarbonization
Transportation Research Interdisciplinary PerspectivesAviation faces a structural paradox: five decades of efficiency gains have been absorbed by traffic growth, and absolute emissions continue to rise. Existing sector-wide decarbonization scenarios from ICAO and IATA rest almost entirely on Sustainable ...

High-speed devices for modular reduction with minimal hardware costs
Cogent Engineering, 2019 Asymmetric cryptosystems have an important advantage over symmetric systems, since only the public key is transmitted. However, asymmetric cryptographic algorithms have a lower speed compared to symmetric ones.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

High-Speed Algorithms and Architectures for Range Reduction Computation
IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2011 Range reduction is a crucial step for accuracy in trigonometric functions evaluation. This paper shows and compares a set of algorithms for additive range reduction computation and their corresponding application-specific integrated circuit implementations (ensuring an accuracy of one unit in the last place).

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Dataset Reduction Techniques to Speed Up SVD Analyses on Big Geo-Datasets
ISPRS International Journal of Geo-Information, 2019 The Singular Value Decomposition (SVD) is a mathematical procedure with multiple applications in the geosciences. For instance, it is used in dimensionality reduction and as a support operator for various analytical tasks applicable to spatio-temporal ...

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.
