The coupling factor ATPase (F1) from photosynthetic membranes of the cyanobacterium Spirulina platensis was purified to homogeneity by a combination of ion-exchange chromatography and sucrose density gradient centrifugation. The ATPase activity of purified Spirulina F1 is latent but can be elicited by trypsin treatment, resulting in specific activities (CaATPase) of 27-37 mumol Pi min-1 mg prot...

We define and study the category Rep(Q, F1) of representations of a quiver in Vect(F1) the category of vector spaces ”over F1”. Rep(Q, F1) is an F1–linear category possessing kernels, co-kernels, and direct sums. Moreover, Rep(Q, F1) satisfies analogues of the Jordan-Hölder and Krull-Schmidt theorems. We are thus able to define the Hall algebra HQ of Rep(Q, F1), which behaves in some ways like ...

Our group within the University of Amsterdam participated in the large-scale visual concept detection task of ImageCLEF 2010. The submissions from our visual concept detection system have resulted in the best visual-only run in the per-concept evaluation. In the per-image evaluation , it achieves the highest score in terms of example-based F-measure across all types of runs.

This paper describes our system for detection and interpretation of English puns. We participated in 2 subtasks related to homographic puns achieve comparable results for these tasks. Through the paper we provide detailed description of the approach, as well as the results obtained in the task. Our models achieved an F1-score of 77.65% for Subtask 1 and 52.15% for Subtask 2.

We define the field F1 of one element as a λ-ring Z with the canonical λ-structure. We show that we can calculate the Riemann zeta function of integers in two ways: the first, geometrical, as the zeta function of the affine line F1[x] over F1 and the second, categorical, using a suitable category of modules over F1.

Genetic variation and inheritance of randomly amplified polymorphic DNA (RAPD) markers in female grass carp (Ctenopharyngodon idella) and male bighead carp (Hypophthalmichthys nobilis) and their F1 offspring hybrid have been studied. For this purpose, genomic DNA was extracted from muscle tissue according to phenol-chloroform method, and six decamer primers were used for amplifying polymorphic ...

Given a power q of a prime number p and “nice” polynomials f1, . . . , fr ∈ Fq[T, X] with r = 1 if p = 2, we establish an asymptotic formula for the number of pairs (a1, a2) ∈ Fq such that f1(T, a1T + a2), . . . , fr(T, a1T + a2) are irreducible in Fq[T ]. In particular that number tends to infinity with q. MR Classification: 12E30 Directory: \Jarden\Diary\BSJ 23 December, 2011 * Alexander von ...

Let X1 X2 be a sequence of pairwise negatively dependent random variables with distributions F1 F2 on − , and let S n be the maximum of its first n partial sums S1 Sn. This article studies the asymptotic tail probabilities of Sn and S n . Under suitable regularity conditions on the distributions F1 Fn, we prove that both P Sn > x and P S n > x are asymptotic to ∑n i=1 1− Fi x as x → , indicatin...
