We construct quasiconformal mappings in Euclidean spaces by integration of a discontinuous kernel against doubling measures with suitable decay. The differentials of mappings that arise in this way satisfy an isotropic form of the doubling condition. We prove that this isotropic doubling condition is satisfied by the distance functions of certain fractal sets. Finally, we construct an isotropic...

The authors present the central capacity sharing (CCS) model and derive equations describing its behaviors to explain results from dual-task situations. The predictions of the CCS model are contrasted with those of the central bottleneck model. The CCS model predicts all of the hallmark effects of the psychological refractory period (PRP) pardigm: -1 slope of the PRP effect at short stimulus on...

Stimuli that are clearly positive or negative (hence valence-laden stimuli) have the potential to interrupt unrelated task processing. A typical example is the emotional Stroop effect (ESE) in which responding to a certain task feature (e.g., color) is delayed by the presentation of task-irrelevant valent stimuli (e.g., negative pictures) compared to valence-neutral stimuli. Here we scrutinize ...

Two species in the genera Neoperla and Kamimuria (Plecoptera: Perlidae) from China are described as new: Kamimuria guangxia sp. n., and Neoperla mesostyla sp. n. The new species are compared to similar taxa.

Modern day stock markets have almost entirely became automated. Even though it means increased profits for the investors by algorithms acting upon the slightest price change in order of microseconds, it also has given birth to many ethical dilemmas in the sense that slightest mistake can cause people to lose all of their livelihoods. This paper reviews one such event that happened on May 06, 20...

The sugarbeet cyst nematode, Heterodera schachtii Schmidt, 1871, was discovered by Mai et al. (4) in fields of 16 New York State commercial red table beet growers during a survey in 1970-1971. They reported that the clover cyst nematode, H. trifolii Goffart, 1932, which also has lemon-shaped cysts with bullae, was present in very low numbers in many of the fields sampled. Thus a rapid and relia...

In this paper we introduce a new coalitional value in the context of TU games with an a priori system of unions, which it is called the symmetric coalitional Banzhaf value. This value satisfies the property of symmetry in the quotient game, the quotient game property, and it is a coalitional value of Banzhaf. Several characterizations are provided and two political examples illustrate the diffe...

This paper proposes an extension of the Identity model developed by Akerlof and Kranton (2000) that incorporates a beliefs dimension based on the consumption of information. The model is then applied to the process by which consumer-voters consume campaign media and selectively accept information to vote. Based on the assumption that political parties act to maximize their stream of future cont...

The microalga incorporated photobioreactor is a highly efficient biological system for converting CO2 into biomass. Using microalgal photobioreactor as CO2 mitigation system is a practical approach for elimination of waste gas from the CO2 emission. In this study, the marine microalga Chlorella sp. was cultured in a photobioreactor to assess biomass, lipid productivity and CO2 reduction. We als...

In this issue Health by Numbers explores asthma hospitalizations and emergency department (ED) visit rates in relation to Healthy People 2010 (HP2010) goals. Two HP2010 objectives for asthma are specific to hospitalizations and ED visits. Objective 24-2 sets the following targets for asthma hospitalizations by age group: (1) an age-specific rate of 25 per 10,000 children under age 5 years, (2) ...
