10-Hydrazino-BODIPY, BoNHNH , presents slow rotation about the C10-NH bond that results in anisochronous H and C NMR signals. The assignment of the different signals has been made using traditional two-dimensional methods as well as spin-spin coupling constants and confirmed by DFT calculations (B3LYP) using the 6-311++G(d,p) basis set. The rotational barrier has been determined in three pairs of proton signals and compared with the calculated barrier.

The increasing use of blood-contacting medical devices has brought about significant advancements in patient care, yet it also presents challenges such as thrombus formation and infection risks. Surface coatings play a vital role in mitigating these side effects, enhancing the safety and effectiveness of such devices. In this study, we introduced a novel coating employing poly(aspartic acid) (PASP), which can be easily applied through various modification pathways.

Neuronal heterogeneity, characterized by a multitude of spiking neuronal patterns, is a widespread phenomenon throughout the nervous system. In particular, the brain exhibits strong variability among inhibitory neurons. Despite the huge neuronal heterogeneity across brain regions, which in principle could decrease synchronization due to differences in intrinsic neuronal properties, cortical areas coherently oscillate during various cognitive tasks.

Bismuth ferrite (BiFeO) is a semiconductor with multiferroic properties, synthesized by the sol-gel method. While static high-pressure studies have advanced our understanding of the phase behavior of BiFeO, the effects of dynamic pressure acoustic shock waves remain unexplored. In this study, BiFeO was subjected to 100 shock pulses with 0.

The increasing complexity and volume of radiology reports present challenges for timely critical findings communication. To evaluate the performance of two out-of-the-box LLMs in detecting and classifying critical findings in radiology reports using various prompt strategies. The analysis included 252 radiology reports of varying modalities and anatomic regions extracted from the MIMIC-III database, divided into a prompt engineering tuning set of 50 reports, a holdout test set of 125 reports, and a pool of 77 remaining reports used as examples for few-shot prompting.
