The racemic title compound, C(24)H(20)N(2), gives spontaneous resolution with the formation of conglomerate crystals in the space group P2(1)2(1)2(1) when crystallized from ethyl acetate. The twisted mol-ecules pack in parallel regions (ab plane) which then form a herringbone pattern along c.

In the pair of helical conformational polymorphs of the coordination polymer {[AgL](CF3SO3)}infinity(L=2-pyridinyl-3-pyridinylmethanone), the 2(1) helices of opposite chirality in one supramolecular isomer are stacked alternately to form a racemate, while the 4(1) helices in the other are assembled homochirally by inter-chain argentophilic interaction to generate a conglomerate.

We demonstrate that limited market participation can arise endogenously in the presence of model uncertainty. Our model generates novel predictions on the relation between limited market participation, the equity premium, and the diversification discount. When the dispersion in investors’ model uncertainty is small, full market participation prevails in equilibrium. In this case, the equity pre...

A thin (3–25 cm), persistent conglomerate-sandstone unit occurs at the base of the transgressive systems tract of an Upper Pennsylvanian cyclothem below a transgressive limestone in outcrop and subsurface in SE Kansas and NE Oklahoma. It has an erosional base and a sharp top, and is composed of calcitic clasts, some shell fragments and quartz sand, and rare coal fragments. Clasts are rounded, e...

OBJECTIVES/HYPOTHESIS Knowledge of histopathological factors, such as perineural invasion (PNI), extracapsular spread (ECS), angiolymphatic vessel invasion, and conglomerate lymph nodes, in patients with head and neck squamous cell carcinoma is important for appropriate treatment decisions. Given the availability of aggressive therapeutic options with known side effects and burdens for the pati...
