Recent experimental studies suggest that risk aversion is negatively related to cognitive ability. In this paper we report evidence that this relation might be spurious. We recruit a large subject pool drawn from the general Danish population for our experiment. By presenting subjects with choice tasks that vary the bias induced by random choices, we are able to generate both negative and posit...

We study the convergence of the population dynamics algorithm, which produces sample pools of random variables having a distribution that closely approximates that of the special endogenous solution to a stochastic fixed-point equation of the form: R D = Φ(Q,N, {Ci}, {Ri}), where (Q,N, {Ci}) is a real-valued random vector with N ∈ N, and {Ri}i∈N is a sequence of i.i.d. copies of R, independent ...

this study assessed the chemical and microbial contents in the water of public swimming pools in akwa ibom state, nigeria. a total of 16 public pools were selected through probability sampling from the 32 pools that existed in the five urban areas of akwa ibom state. water samples were collected from the sampled pools and tested in the laboratory for chemical and microbial contents. results sho...

background: using public swimming pools during different seasons and poor health behavior could be responsible in transmis­sion of fungal disease through pool water and its environment. therefore, this research was conducted to investi­gate fungal agents of indoor public swimming pools of ahwaz, capital city of khouzestan province, south-west of iran. methods : ten indoor swimming pools of ahwa...

Abstract—In a random key graph (RKG) of n nodes each node is randomly assigned a key ring of Kn cryptographic keys from a pool of Pn keys. Two nodes can communicate directly if they have at least one common key in their key rings. We assume that the n nodes are distributed uniformly in [0, 1]. In addition to the common key requirement, we require two nodes to also be within rn of each other to ...

Aim Our aim was to investigate how the environment, species characteristics and historical factors at the subcontinental scale affect patterns of diversity. We used the assembly of the Yellowstone biota over the past 10,000 years as a natural experiment for investigating the processes that generate a modern non-volant mammal species pool. Location The data represent species from throughout Nort...

Metals and alloys fabricated by fusion-based additive manufacturing (AM), or 3D printing, undergo complex dynamics of melting solidification, presenting challenges to the effective control grain structure. Herein, we report on use high-intensity ultrasound that controls process solidification during AM 316L stainless steel. We find favours columnar-to-equiaxed transition, promoting formation fi...
