This paper examines firms’ incentives to commit to a transparent behavior (that precludes bribery) in a competitive procedure modeled as an asymmetric information beauty contest managed by a corrupt agent. In his evaluation of firms’ offers for a public contract the agent has some discretion to favor a firm in exchange of a bribe. It is shown that a conditional commitment mechanism can eliminat...

In the title compound, 2C(15)H(17)NOS·C(12)H(24)O(6), the asymmetric unit consists of one N-oxide derivative and one-half of the 18-crown-6 ether, which lies on an inversion centre. In the crown ether, the O-C-C-O torsion angles indicate a gauche conformation of the ethyl-eneoxy units, while the C-O-C-C torsion angles indicate planarity of these segments. In the N-oxide unit, the dihedral angle...

Acid sphingomyelinase deficiency (ASMD), also historically known as Niemann-Pick disease A (OMIM #257200) and B (OMIM#607616), is a rare debilitating lysosomal storage caused by pathogenic variants in SMPD1 gene. Deficient activity of the enzyme acid (ASM) leads to sphingomyelin accumulation various organs. Visceral manifestations ASMD include interstitial lung pulmonary dysfunction, splenomegal...

There are circular square-free words of length n on three symbols for n ≥ 18. This proves a conjecture of R. J. Simpson.

N,N'-bis (1-naphthylmethyl)-diaza-18-crown-6 (1) showed weak emissions, suggesting that photoinduced electron transfer (PET) from the amine group to the excited naphthalene occurs. The PET fluoroionophore (1) was found to display unique photophysical properties in the presence of a guest cation. Single crystals of the HNCS salt of 1 were grown from 1 and NH(4)SCN. The crystal structure of the H...

The asymmetric unit of the title compound, [K(C(3)H(3)N(2))(C(12)H(24)O(6))], is composed of a potassium cation bonded to the six O atoms of a crown ether mol-ecule and the two N atoms of a pyrazolate anion. The K⋯O distances range from 2.8416 (8) to 3.0025 (8) Å, and the two K⋯N distances are 2.7441 (11) and 2.7654 (11) Å. The K cation is displaced by 0.8437 (4) Å from the best plane through t...
