TL;DR: In this article, the authors investigated the improvement in financial performance that is associated with the use of activity-based costing (ABC), and the conditions under which such improvement is achieved, finding that there indeed is a positive association between ABC and improvement in ROI when ABC is used concurrently with other strategic initiatives, when implemented in complex and diverse firms, when used in environments where costs are relatively important, and when there are limited numbers of intra-company transactions.

TL;DR: It is proposed that this unique ability of the peptides to induce nonbilayer structures in phosphatidylcholine model membranes is due to the presence of two tryptophans at both sides of the membrane/water interface, which prevent the peptide from aggregating when the mismatch is increased.
Abstract: We have investigated the effect of several hydrophobic polypeptides on the phase behavior of diacylphosphatidylcholines with different acyl chain length. The polypeptides are uncharged and consist of a sequence with variable length of alternating leucine and alanine, flanked on both sides by two tryptophans, and with the N- and C-termini blocked. First it was demonstrated by circular dichroism measurements that these peptides adopt an α-helical conformation with a transmembrane orientation in bilayers of dimyristoylphosphatidylcholine. Subsequent 31P NMR measurements showed that the peptides can affect lipid organization depending on the difference in hydrophobic length between the peptide and the lipid bilayer in the liquid-crystalline phase. When a 17 amino acid residue long peptide (WALP17) was incorporated in a 1/10 molar ratio of peptide to lipid, a bilayer was maintained in saturated phospholipids containing acyl chains of 12 and 14 C atoms, an isotropic phase was formed at 16 C atoms, and an invert...

TL;DR: This work argues that the division of choice into reinforcing value versus delay discounting is based on an arbitrary definition based on the temporality of choices, and presents a model that integrates reinforcing value and Delay discounting approaches.

TL;DR: Stable and reproducible superconductivity has been unambiguously observed in a new Tl-Ba-Cu-O system containing no group-IIIB elements and further substitutions of elements for this system may lead to even higher-temperature superconductors.
Abstract: Stable and reproducible superconductivity has been unambiguously observed in a new Tl-Ba-Cu-O system containing no group-IIIB elements. Resistance in these rare-earth--free oxides starts to drop sharply above 90 K and reaches zero at 81 K. Meissner flux expulsion and diamagnetic shielding show bulk superconductivity. Further substitutions of elements for this system may lead to even higher-temperature superconductors.

TL;DR: There is a need for future studies to identify markers for WS and WB in live birds and genetic, nutritional, and/or management strategies to alleviate the condition.
