Spatial hearing relies on the encoding of perceptual sound location cues in space. It is critical for communicating in background noise, and understanding where sounds are coming from (sound localization). Although there are some monoaural spatial hearing cues (i.

- Neoadjuvant radiotherapy is crucial for treating locally advanced rectal cancer, and this study compares the quality-of-life outcomes between two techniques: three-dimensional conformal radiotherapy (3DCRT) and intensity-modulated radiotherapy (IMRT).
- A phase II randomized trial involved 94 patients who received chemoradiotherapy and were assigned to either 3DCRT or IMRT; their quality of life was assessed using specific questionnaires throughout the treatment and at a six-month follow-up.
- Although the trial ended early due to the futility of its primary endpoint, the results indicated that while emotional functioning improved, other aspects of quality of life declined; notably, IMRT showed better physical and role functioning during the final week
Reactions of a m-terphenylhydridostannylene with β-diketiminato magnesium and calcium hydrides provide bis-μ-hydrido species, the heterobimetallic constitutions of which are maintained after the addition of THF donor solvent. In both cases, reactions with hex-1-ene result in the formation of tetravalent organostannyl alkaline earth derivatives. Whereas the magnesium reagent undergoes facile twofold addition, the calcium-centered process is arrested after a single alkene reduction event.

Addition of THF, however, induces deprotonation and access to monomeric Ae-germanide complexes, [(BDI)Ae{GePh}(THF)], both of which have been structurally characterized. Although this process is facile when Ae=Ca, the analogous magnesium-based reaction requires heating to temperatures >100 °C, under which conditions germanide formation is complicated by THF ring opening and the generation of an alkaline earth germyl-C-terminated n-butoxide, [(BDI)Mg{μ-O(CH)GePh}].

Crystallization of also results in the formation of its noncyclometalated isomer, [Ir(IPr)(ZnMe)][BAr], , in the solid state.
