The choice for specific parameter estimation methods is often more dependent on its availability than its performance. We developed SPOTPY (Statistical Parameter Optimization Tool), an open source python package containing a comprehensive set of methods typically used to calibrate, analyze and optimize parameters for a wide range of ecological models. SPOTPY currently contains eight widely used...

We prove the local inequality A≥8π|J|, where A and J are the area and angular momentum of any axially symmetric closed stable minimal surface in an axially symmetric maximal initial data. From this theorem it is proved that the inequality is satisfied for any surface on complete asymptotically flat maximal axisymmetric data. In particular it holds for marginal or event horizons of black holes. ...

Let [Formula: see text] be a generalized Calderón-Zygmund operator or [Formula: see text] ( the identity operator), let [Formula: see text] and [Formula: see text] be the linear operators, and let [Formula: see text]. Denote the Toeplitz type operator by [Formula: see text]where [Formula: see text] and [Formula: see text] is fractional integral operator. In this paper, we establish the sharp ma...

We start with a very brief description of the principal events in the history of our subject. About 1870 M.Noether discovered [N] that the group of birational automorphisms of the projective plane BirP, which is known also as the Cremona group CrP, is generated by its subgroup AutP = AutC/C and any quadratic Cremona transformation τ , which in a certain system of homogeneous coordinates can be ...

We show that in all dimensions d ≥ 3, there exists an asymmetric convex body of revolution all of whose maximal hyperplane sections have the same volume. This gives the negative answer to the question posed by V. Klee in 1969.

background: cesarean section (c-section) in the north of iran accounts for 70% of childbirths, which is higher than the national average of 55%. understanding women’s perceptions towards modes of delivery in different cultures can pave the way for promoting programs and policies in support of vaginal delivery. we aimed to investigate women’s perceptions towards modes of delivery in the north of...

The study aims to gain a better understanding of sexual harassment acts experienced by female passengers on the Bus Rapid Transport (BRT) operated UDART in Dar es Salaam, Tanzania, and recommend factors for reducing practice. specifically investigated that contribute harassment, passenger coping strategies with alleviating harassment. In-depth interviews approximately 30 women who regularly use...
