N-Aryl sulfamoyl fluorides (ArSAFs) are hydrolytically stable motifs widely used in drug design, yet their suitability for radiotracer development has not been explored. Here, we report the efficient radiosynthesis of [18F]ArSAFs by base-free sulfur(VI) fluoride exchange (SuFEx), affording high molar activities from nanomolar precursor amounts. [...]

Emerging Kolmogorov–Arnold networks (KANs) replace the linear weights of neural networks with trainable nonlinear functions. This modification is particularly attractive for scientific computing, where KANs can match the accuracy of conventional multilayer perceptrons (MLPs) while reducing model size by up to 100×. [...]

Logic-in-memory (LiM) has emerged as a promising paradigm to address the von Neumann bottleneck by integrating data storage and in-situ computation. Resistive random-access memory (RRAM) is a strong candidate for LiM owing to its non-volatility, fast switching characteristics, and compatibility with CMOS integration. [...]

Libyan Desert Glass (LDG) is an ~29 million years old, silica-rich glass found in Western Egypt. Whether this glass formed in an impact cratering context associated with the hypervelocity collision of a cometary/asteroidal body or radiative heating during an airburst is debated. [...]

The proposed prototype Canadian Compact Accelerator-driven Neutron Source (PC-CANS) presents a cost-effective solution to address the shrinking global availability of neutron beams. Designed to support a range of applications, including Small Angle Neutron Scattering (SANS), neutron imaging, boron neutron capture therapy, and radioisotope production, PC-CANS aims to restore and enhance Canada’s neutron science capabilities. [...]

Radiative decays of hadronic states provide an essential source of information that can facilitate deciphering their nature and properties. However, a lot of confusion concerning radiative decays of hadronic molecules and their interpretation can be found in the literature. [...]

Absorption of hydrogen in thin films is important for a wide range of applications, including hydrogen membranes, sensor technology, and programmable resistors for artificial neural networks. In this study, we demonstrate that analysing the kinetics of the absorption process with a combination of direct and indirect methods provides a much clearer and more detailed picture of the individual processes involved than the usual investigations in thermodynamic equilibrium do.
