1 It is stated that dimS4 Γ0 47 , 1 5 at page 643 in 1 . But this dimension is 11 as stated at page 299 in 2 . Therefore, the coefficients of power series in 2.2 , 2.3 , 2.5 , 2.6 , 2.7 , 2.8 , 2.10 , 2.12 , 2.14 , 2.15 , 2.20 , and 2.22 have to be calculated up to z11, and Theorem 2.4 and consequently Theorem 2.7 are false since 5 vectors cannot be a basis of 11-dimensional vector space. 2 The...

(1) zd = { i √ d 2 if d ≡ 0 (mod 4), −1+i √ d 2 if d ≡ 3 (mod 4). The j-function has the remarkable property that j(zd) is an algebraic integer of degree h(−d), the class number of K = Q(zd). In fact, K(j(zd)) is the Hilbert class field of K [4]. The first few values of j(zd) are: j(z3) = 0, j(z4) = 12 , j(z7) = −153, j(z8) = 20, j(z11) = −323 j(z15) = −191025−85995√5 2 , j(z19) = −963, j(z20) ...

We document the existence of pricing styles in the concert industry. Artists differ in the extent to which they rely on secondand third-degree price discrimination and in how likely they are to sell out concerts. Most strikingly, artists who use multiple seating categories are more likely to vary prices across markets and less likely to sell out concerts. These patterns are difficult to explain...

BACKGROUND Moths (Lepidoptera) are highly dependent on chemical communication to find a mate. Compared to conventional unselective insecticides, synthetic pheromones have successfully served to lure male moths as a specific and environmentally friendly way to control important pest species. However, the chemical synthesis and purification of the sex pheromone components in large amounts is a di...

in this study an easy, green, efficient and simple approach is reported for the synthesis of some benzothiazole-, benzimidazole- and benzoxazole-2-thiolderivatives. the proposed approach employs the reaction of corresponding aromatic amine with potassium isopropyl xanthate (z11) in the presence of copper sulfate (cuso4) as a catalyst under conventional heating and ultrasonic irradiation. the ad...

Sexual behavior of male moths after prolonged exposure to the 1-ng pheromone/m(3) air previously measured in orchards treated with pheromone for mating disruption was examined in a flight tunnel. The exposure of Grapholita molesta (Busck) to 1-ng (Z)-8-dodecen-1-yl acetate (Z8-12:OAc)/m(3) air for 15 min had no effect on their ability to fly upwind to a conspecific, virgin calling female. Afte...

In insects and other animals, intraspecific communication between individuals of the opposite sex is mediated in part by chemical signals called sex pheromones. In most moth species, male moths rely heavily on species-specific sex pheromones emitted by female moths to identify and orient towards an appropriate mating partner among a large number of sympatric insect species. The silkmoth, Bombyx...
