The authors of "Relatedness, Conflict, and the Evolution of Eusociality" respond to objections raised by Martin Nowak and Benjamin Allen.

Cluttering is a disability in formulating language, causing confused, hurried and slurred diction, due to congenital and constitutional limitation of one’s total psychosomatic personality structure. Schizophrenia is a psychotic disorder characterized by hallucinations, delusions, disorganized thoughts/speech, disorganized behavior and apathy. This study aimed to investigate the prevalence and c...

Considering the strategic importance of quality assurance and enhancement in higher education, this paper aims to address questions such as: How can we improve the quality of educational processes and outcomes? How can we involve the grassroots level both teachers and students? Which is the role of reflective practice and self-evaluation in this endeavour? Reference will be made to the "QualiTr...

This paper describes a procedure for making topologically complex three-dimensional microfluidic channel systems in poly(dimethylsiloxane) (PDMS). This procedure is called the "membrane sandwich" method to suggest the structure of the final system: a thin membrane having channel structures molded on each face (and with connections between the faces) sandwiched between two thicker, flat slabs th...

Formal asymptotic expansions have long been used to study the singularly perturbed Allen-Cahn type equations and reaction-diffusion systems, including in particular the FitzHugh-Nagumo system. Despite their successful role, it has been largely unclear whether or not such expansions really represent the actual profile of solutions with rather general initial data. By combining our earlier result...

A real aether model of the vacuum proposed by Allen Rothwarf(1) based upon a degenerate Fermion fluid, composed of polarizable particle-antiparticle pairs, leads to a big bang model of the universe where the velocity of light varies inversely with the square root of the cosmological time. Here this model is used to determine the time dependence of certain fundamental constants, i.e., permittivi...

We study the evolution of fronts in a bistable equation with time-delayed global feedback in the fast reaction and slow diffusion regime. This equation generalizes the Hodgkin-Grafstein and Allen-Cahn equations. We derive a nonlinear equation governing the motion of fronts, which includes a term with delay. In the one-dimensional case this equation is linear. We study the motion of one- and two...
