Importance: Recent longitudinal studies in patients with unruptured intracranial aneurysms (UIAs) suggested that aneurysm wall enhancement (AWE) on magnetic resonance imaging (MRI) predicts growth and rupture. However, because these studies were limited by small sample size and short follow-up duration, it remains unclear whether this radiological biomarker has predictive value for UIA instability.
Objective: To determine the 4-year risk of instability of UIAs with AWE and investigate whether AWE is an independent predictor of UIA instability.

Purpose: The aim of this in vitro study was to assess whether the accuracy (trueness and precision) of full-arch implant digital impressions can be improved by replacing standard digital impressions (StDIs) with segmented digital impressions (SgDIs), obtained by superimposing short-span digital impressions using a geometric pattern.
Materials And Methods: The study was conducted using a commercial edentulous maxillary model with four implants-positioned at the sites of the canines and second molars-and four commercial intraoral scan bodies (ISBs) screwed to them. Ten StDIs and SgDIs of the model were obtained, and their accuracy was evaluated and compared in terms of trueness and precision, based on measurements of three distances and three angles between the ISBs.

The iron(I) dinitrogen complex PhB(AdIm)FeN, which is supported by a very bulky 1-adamantyl-substituted tris(carbene)borate ligand, reacts with equimolar CO at low temperature to afford the high spin ( = 3/2) complex PhB(AdIm)Fe(CO). This monocarbonyl complex reacts with additional CO to afford the low spin ( = 1/2) dicarbonyl complex PhB(AdIm)Fe(CO). By contrast, the high spin iron(I) tris(pyrazolyl)borate complex TpFe(CO) does not react with additional CO.

Purpose: To establish an explainable machine learning (ML) approach using patient-related and noncontrast chest CT-derived features to predict the contrast material arrival time (TARR) in CT pulmonary angiography (CTPA).
Materials And Methods: This retrospective study included consecutive patients referred for CTPA between September 2023 to October 2024. Sixteen clinical and 17 chest CT-derived parameters were used as inputs for the ML approach, which employed recursive feature elimination for feature selection and XGBoost with SHapley Additive exPlanations (SHAP) for explainable modeling.

An improved rotational characterization of the E3Σ1+(63S1) Rydberg state of the CdAr diatom produced in a supersonic beam and studied using laser induced fluorescence (LIF) excitation spectra is presented. As an example, the spectra of the E3Σ1+←A3Π0+(53P1) transition, originating from the excitation of a single 116Cd40Ar isotopologue, are recorded and analyzed. In the experiment, the optical-optical double resonance method is employed, utilizing the E3Σ1+(υ')←A3Π0+(53P1)(υ″=6)←X1Σ0+(υ=0) scheme.
