Social insect colonies typically have well-defined social and physical boundaries but in some cases, colonies may take-on a more diffuse form with no obvious nestmate recognition or inter-colony aggression. Why colonies adopt closed versus open societies is not well understood, but it is presumably related to the genetic or environmental identity of individuals. In this study, we use Canadian populations...
The increased demand for low dielectric constant (k<3.0) chemical vapor deposited polymer thin films to replace SiO2 (k=3.9–4.3) to reduce RC-delay in ultra large scale integration (ULSI) devices has prompted the synthesis of many new polymers. However, the ultimate properties of the polymer thin film are determined by its molecular structure that for polymers is often anisotropic. A basic understanding...
