Multicomponent methods seek to treat select nuclei, typically protons, fully quantum mechanically and equivalent the electrons of a chemical system. In such methods, it is well-known that due neglect electron–proton correlation, Hartree–Fock (HF) description interaction catastrophically fails leading qualitatively incorrect protonic properties. single-component chemistry, qualitative failure HF...

A slip asymmetry can break the fore–aft symmetry of local hydrodynamic force distribution on surface an otherwise no-slip or uniform-slip particle. Here, we use Lorentz reciprocal theorem to demonstrate that such asymmetry, even in a fractional amount, qualitatively alter swimming characteristics self-propelled spherical squirmer, markedly different from those squirmers. Unlike usual tangential...

Eukaryotic genomes are packaged by the wrapping of DNA around histone octamers to form nucleosomes. Nucleosome occupancy, acetylation, and methylation, which have a major impact on all nuclear processes involving DNA, have been recently mapped across the yeast genome using chromatin immunoprecipitation and DNA microarrays. However, this experimental protocol is laborious and expensive. Moreover...

The cognitive maps that humans compute as representations of the spatial environment they have visited are rarely even close approximations to what was actually experienced. When we experience the environment we seem to see it all so perfectly, yet rarely are we able to reproduce from memory an exact description of the places visited. Yet these vague, muddled descriptions of the places visited ...

ABSTRACT To investigate the neural mechanisms that humans u...

Education has been slow to capitalize on the significant potential benefits to learning of the increased use of information technologies because teachers have, by and large, used them to automate existing classroom practices. A recent innovative Australian project sought to scale up the use of e-learning by giving students and teachers more equity in the development of projects. Students determ...

This paper contains a critical review of the claim that evaluative conditioning (EC) represents a theoretically distinct form of classical conditioning. A review of the evidence suggests that: (i) while it is claimed that EC can occur without awareness, EC studies have either adopted inappropriate statistical comparisons to demonstrate this or have failed to use the control conditions necessary...

We examine a particular kind of six-dimensional Cremonian universe featuring one dimension of space, three dimensions of time and other two dimensions that cannot be ranked as either time or space. One of these two, generated by a one-parametric aggregate of (straight-)lines lying on a quadratic cone, is more similar to the spatial dimension. The other, represented by a singly-parametrical set ...
