Introduction Perforated sheets are used in a number of industrial applications e.g. the shadow masks in colour monitor and television tubes. Their design requires the characterization of the deformation behaviour of a perforated sheet containing a large number of tiny holes. In practice, the holes are varying through the sheet thickness, however, in modelling this inhomogeneity is mostly ignore...

The toughness and coefficient of thermal expansion of a series of functionalized graphene sheet epoxy nanocomposites are investigated. Functionalized graphene sheets are produced by splitting graphite oxide into single graphene sheets through a rapid thermal expansion process. These graphene sheets contain ~ 10% oxygen due to the presence of hydroxide, epoxide, and carboxyl functional groups wh...

In the course of counter-insurgency campaigns, military forces expend considerable resources and time conducting cordon and search operations in an effort to interdict and suppress criminal groups. However, these operations have a low success rate, with most operations yielding little intelligence or marginal tactical gains while simultaneously angering the local populace. This paper demonstrat...

T paper presents the authors’ rejoinder to Zeithammer and Adams [Zeithammer, R., C. Adams. 2010. The sealed-bid abstraction in online auctions. Marketing Sci. 29(6) 964–987]. This rejoinder clarifies and qualifies conclusions of the original paper and makes suggestions for fruitful areas of future research. In particular, the original paper shows that bidding style can make a big difference in ...

The potential benefits of collaboration technologies are typically realized only in groups led by collaboration experts. This raises the facilitator-in-the-box challenge: Can collaboration expertise be packaged with collaboration technology in a form that nonexperts can reuse with no training on either tools or techniques? We address that challenge with process support applications (PSAs). We d...

Cardiospheres (CSs) are self-assembling multicellular clusters from the cellular outgrowth from cardiac explants cultured in nonadhesive substrates. They contain a core of primitive, proliferating cells, and an outer layer of mesenchymal/stromal cells and differentiating cells that express cardiomyocyte proteins and connexin 43. Because CSs contain both primitive cells and committed progenitors...

We discuss Gubser-Klebanov-Polyakov proposal for the gauge/string theory correspondence for gauge theories in curved space. Specifically, we consider KlebanovTseytlin cascading gauge theory compactified on S. We explain regime when this gauge theory is a small deformation of the superconformal N = 1 gauge theory on the world volume of regular D3-branes at the tip of the conifold. We study close...

Multilayered cell sheets have been produced from bone marrow-derived mesenchymal stem cells (MSCs) for investigating their adhesion properties onto native porcine heart tissue. Once MSCs reached confluence after a 7-day culture on a temperature-responsive culture dish, a MSCs monolayer spontaneously detached itself from the dish, when the culture temperature was reduced from 37 to 20°C. The bas...
