Article Abstract
We have developed a tandem method essential for synthesizing sulfone-containing organic molecules, which has wide-ranging applications in agrochemicals, medicinal chemistry, and polymer science. This method involves a two-step process: an iodo-sulfonylated intermediate is formed initially, followed by elimination to regenerate the double bond, ultimately yielding sulfone-containing cyclopropenes. Control studies have confirmed the intermediacy of iodo-sulfonylated cyclopropane within the reaction sequence. Additionally, this protocol demonstrated an excellent tolerance for various functional groups. Moreover, the resulting sulfonylated-cyclopropenes are promising synthons for late-stage modification and molecular diversification.

This study addresses historical uncertainties regarding morphological variation in the paraprocts of Tupiperla illiesi, a stonefly with a complex taxonomic history. We tested whether these variations represent phenotypic plasticity or distinct species using integrative taxonomy. Adult gripopterygids were collected from Estação Biológica de Boracéia utilizing Malaise and light traps.

Large language models (LLMs) have been successfully used for data extraction from free-text radiology reports. Most current studies were conducted with LLMs accessed via an application programming interface (API). We evaluated the feasibility of using open-source LLMs, deployed on limited local hardware resources for data extraction from free-text mammography reports, using a common data element (CDE)-based structure.

A CoO/AgMoO/CeOternary nanocomposites photocatalyst was successfully synthesized through a straightforward ethanol-assisted chemical method. Comprehensive characterization of its structural and optical properties was conducted using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), Raman spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-Vis diffuse reflectance spectroscopy (UV-DRS), and photoluminescence (PL) analysis. XRD analysis confirmed the presence of CoO, AgMoO and CeO in the ternary composite sample.

It has been noticed that when the waiting time distribution exhibits a transition from an intermediate time power-law decay to a long-time exponential decay in the continuous time random walk model, a transition from anomalous diffusion to normal diffusion can be observed at the population level. However, the mechanism behind the transition of waiting time distribution is rarely studied. In this paper, we provide one possible mechanism to explain the origin of such a transition.

Volume correlative light and electron microscopy (vCLEM) is a powerful imaging technique that enables the visualization of fluorescently labeled proteins within their ultrastructural context. Currently, vCLEM alignment relies on time-consuming and subjective manual methods. This paper presents CLEM-Reg, an algorithm that automates the three-dimensional alignment of vCLEM datasets by leveraging probabilistic point cloud registration techniques.
