Community ecology is in a current state of creative ferment, stimulated by the development of neutral models of community organization. Here, I reflect on recent papers by Scheffer and van Nes, and by Gravel et al., which illuminate how neutrality can emerge from ecological and evolutionary processes, thus suggesting ways to unify neutral and niche perspectives.

In this paper, we attempt to correct a popularity bias, which is the tendency for popular items to be recommended more frequently, by enhancing recommendation neutrality. Recommendation neutrality involves excluding specified information from the prediction process of recommendation. This neutrality was formalized as the statistical independence between a recommendation result and the specified...

Many enzymes in intermediary metabolism manifest saturation kinetics in which flux is a concave function of enzyme activity and often of the MichaelisMenten form. The result is that, when natural selection favors increased enzyme activity so as to maximize flux, a point of diminishing returns will be attained in which any increase in flux results in a disproportionately small increase in fitnes...

We present strong evidence of Landau states formation in multiwalled carbon nanotubes with metallic or semiconducting outer shells, under magnetic fields as high as 60 T. Magnetoconductance data are found to converge to a gate-independent value for semiconducting shells, whereas for metallic shells, the Landau states introduce a strong reintroduction of backscattering and Fermi level pinning cl...

We construct an algebraic model of the social choice theory. First we give an arithmetic proof of Arrow’s Impossibility Theorem. Next we apply our algebraic method to single-peaked preference domain to establish two theorems. (i) A value of Arrovian social welfare function on single peaked preference domain is single-plateaued with at most two maximal elements. (ii) An ordering by majority voti...

The paper presents some steps for multi-valued representation of neutrosophic information. These steps are provided in the framework of multivalued logics using the following logical value: true, false, neutral, unknown and saturated. Also, this approach provides some calculus formulae for the following neutrosophic features: truth, falsity, neutrality, ignorance, underdefinedness, over-defined...

In recent years, not only ruggedness but also neutrality has been recognized as an important feature of a fitness landscape for genetic search. As it has been reported that the evolutionary dynamics on a fitness landscape with neutrality is clearly different from the canonical explanations, ruggedness alone might be inadequate describing it. Another measure, i.e., neutrality is required. In thi...

This policy brief examines key themes highlighted during a series of roundtable discussions exploring South Asian Perspectives on Net Neutrality, hosted by the Centre for Internet and Society in association with the Annenberg School for Communication, University of Pennsylvania, Observer Research Foundation and IT for Change and provides recommendations for future research agendas on net neutra...
