Human Vitamin K Epoxide Reductase as a Target of Its Redox Protein

Human vitamin K epoxide reductase (hVKORC1) enzymatic activity requires an initial activation by a specific redox protein, a less studied step in the hVKORC1 vital cycle. Significant steric conditions must be met by enzymes, being that to adapt…

Generalized Spectral Clustering for Directed and Undirected Graphs

Spectral clustering is a popular approach for clustering undirected graphs, but its extension to directed graphs (digraphs) is much more challenging. A typical workaround is to naively symmetrize the adjacency matrix of the directed graph, which can…

Serological surveillance for wild rodent infection with SARS-CoV-2 in Europe

We report serological surveillance for exposure to SARS-CoV-2 in 1,237 wild rodents and other small mammals across Europe. All samples were negative with the possible exception of one. Given the ongoing circulation of this virus in humans and…

Improved Sentinel-1 IW Burst Stitching through Geolocation Error Correction Considerations

Since the commissioning phase of Sentinel-1A, several calibration studies have improved the geolocation and geometric modeling of the data. The implementation of the corrections presented in these studies is left to the user. The issues found might…

Transport optimal entre GMM pour la synthèse de texture

L'utilisation du transport optimal est devenue très populaire en traitement d'images, malgré des temps de calcul en grande dimension souvent prohibitifs. Nous proposons ici d'utiliser une formulation alternative récente consistant à restreindre le…

Global tracking and quantification of oil and gas methane emissions from recurrent Sentinel-2 imagery

Methane (CH$_4$) emissions estimates from top-down studies over oil and gas basins have revealed systematic under-estimation of CH$_4$ emissions in current national inventories. Sparse but extremely large amounts of CH$_4$ from oil and gas…

High Dynamic Range and Super-Resolution from Raw Image Bursts

Photographs captured by smartphones and mid-range cameras have limited spatial resolution and dynamic range, with noisy response in underexposed regions and color artefacts in saturated areas. This paper introduces the first approach (to the best of…
