DATA-DRIVEN IMAGING GEOMETRIC RECOVERY OF ULTRAHIGH RESOLUTION ROBOTIC MICRO-CT FOR IN-VIVO AND OTHER APPLICATIONS.

We introduce an ultrahigh-resolution (50) robotic micro-CT design for localized imaging of carotid plaques using robotic arms, cutting-edge detector, and machine learning technologies. To combat geometric error-induced artifacts in interior CT scans, we propose a data-driven geometry estimation method that maximizes the consistency between projection data and the reprojection counterparts of a reconstructed volume. Particularly, we use a normalized cross correlation metric to overcome the projection truncation effect.

To Bond or Not to Bond: Metal-Metal Interaction in Heterobimetallic Rare-Earth Metal-Silver Complexes.

The reaction of 2,4-Bu-6-(PPh)PhOH (HOAr) with silver(I) triflate in a 3:1 molar ratio gave the mononuclear coinage metal complex (HOAr-κ)AgOTf (). Treatment of HOAr with Ln[N(SiMe)] (Ln = La, Sm, Y, Yb) in a 3:1 molar ratio yielded the mononuclear rare-earth metal complexes Ln(OAr-κ,) (). The heterobimetallic rare-earth metal-silver complexes Ln(OTf)(μ-OAr-1κ,2κ)Ag () were prepared from monometallic precursors by reactions of equimolar amounts of with Ln[N(SiMe)] or with silver(I) triflate, respectively.

Rating scales institutionalise a network of logical errors and conceptual problems in research practices: A rigorous analysis showing ways to tackle psychology's crises.

This article explores in-depth the metatheoretical and methodological foundations on which rating scales-by their very conception, design and application-are built and traces their historical origins. It brings together independent lines of critique from different scholars and disciplines to map out the problem landscape, which centres on the failed distinction between psychology's study phenomena (e.g.

Mono- and Disamarium Azacryptand Complexes: A Platform for Cooperative Rare-Earth Metal Chemistry.

Mono- (HLSm) and disamarium complexes (LSm) were prepared by reaction of the azacryptand N[(CH)NHCH--CHCHNH(CH)]N (HL) with 1 or 2 equiv of Sm[N(SiMe)], respectively. The disamarium complex features free coordination sites on both metal centers available for bridging ligands shielded by phenylenes from tetrahydrofuran (THF) coordination. The reaction of LSm with KCN and 18-crown-6 yielded the adduct [LSm-μ-η:η-CN][K(18-crown-6)(THF)] featuring a bridging cyanide.
