Atroposelective Suzuki–Miyaura Coupling to Form 2‐Amino‐2′‐Hydroxybiphenyls Enabled by sRuPhos

open access: yesAngewandte Chemie, EarlyView.
We report a new chiral phosphine ligand, sRuPhos, which permits the highly enantioselective Suzuki–Miyaura coupling of ortho‐aniline and ortho‐phenol building blocks. This results in 2‐amino‐2′‐hydroxybiphenyls with very high enantiomeric excesses, products that will have application in pharmaceutical synthesis and ligand design for catalysis ...

Globally Important Haptophyte Algae Use Exogenous Pyrimidine Compounds More Efficiently than Thiamin

open access: yesmBio, 2017
Vitamin B1 (thiamin) is a cofactor for critical enzymatic processes and is scarce in surface oceans. Several eukaryotic marine algal species thought to rely on exogenous thiamin are now known to grow equally well on the precursor 4-amino-5-hydroxymethyl ...

Agricultural Diversification at the Margin. Strategies and Determinants in Italian Mountain and Remote Areas

open access: yesAgribusiness, EarlyView.
ABSTRACT This paper explores the convergence in on‐farm diversification strategies of agricultural holdings, between remote areas and more central ones. Using Italian farm‐level data, we explore the determinants of diversification strategies across farms.

A New Cytotoxicity Assay for Brevetoxins Using Fluorescence Microscopy

open access: yesMarine Drugs, 2014
Brevetoxins are a family of ladder-framed polyether toxins produced during blooms of the marine dinoflagellate, Karenia brevis. Consumption of shellfish or finfish exposed to brevetoxins can lead to the development of neurotoxic shellfish poisoning.

BMPCQA: Bioinspired Metaverse Point Cloud Quality Assessment Based on Large Multimodal Models

open access: yesAdvanced Intelligent Systems, EarlyView.
This study presents a bioinspired metaverse point cloud quality assessment metric, which simulates the human visual evaluation process to perform the point cloud quality assessment task. It first extracts rendering projection video features, normal image features, and point cloud patch features, which are then fed into a large multimodal model to ...

Cross‐Modal Characterization of Thin‐Film MoS2 Using Generative Models

open access: yesAdvanced Intelligent Systems, EarlyView.
Cross‐modal learning is evaluated using atomic force microscopy (AFM), Raman spectroscopy, and photoluminescence spectroscopy (PL) through unsupervised learning, regression, and autoencoder models. Autoencoder models are used to generate spectroscopy data from the microscopy images.
