Objective: The aim of this study was to perform a comparative pre-clinical evaluation of a new fenestrated endovascular aneurysm repair dedicated stent using perfused 3D printed patient anatomies.
Methods: The test setup included a pulsatile pump set to reproduce human haemodynamics, four 3D printed pararenal aneurysms connected to a bench test, and four corresponding fenestrated grafts (Zenith Fenestrated; Cook, Bloomington, IN, USA). Bridging stents were sized based on analysis of patients computed tomography scans and included either four standard covered stents (BeGraft [BG]; Bentley, Hechingen, Germany) or four similar covered stent grafts mounted on a modified balloon to allow stent implantation and flaring in one step (BeFlared [BF]; Bentley).

Bare silicon dimers on hydrogen-terminated Si(100) have two dangling bonds. These are atomically localized regions of high state density near to and within the bulk silicon band gap. We studied bare silicon dimers as monomeric units.

Synaptic morphology plays a critical role in modulating the dynamics of neurotransmitter diffusion and receptor activation in interneuron communication. Central physical aspects of synaptic geometry, such as the curvature of the synaptic cleft, the distance between the presynaptic and postsynaptic membranes, and the surface area-to-volume ratio of the cleft, crucially influence glutamate diffusion and N-Methyl-D-Aspartate receptor (NMDAR) opening probabilities. In this study, we developed a stochastic model for receptor activation using realistic synaptic geometries.

This study investigates the nature and interplay of noncovalent interactions (NCIs)─tetrel bonds (TB), hydrogen bonds (HB), and halogen bonds (XB)─in molecular assemblies formed between trifluorogermyl hypochlorite (FGeOCl) and hydrogen cyanide (HCN). Using a combination of high-level computational methods, we explored the geometric, energetic, and electronic properties of dimers, trimers, and tetramers formed in different molar ratios of interacting reagents. Various analyses reveal a significant cooperativity between TB and HB, which mutually reinforce each other, while XB interactions are diminished in the presence of TB and HB.
