Business innovation is key to a creating a highly productive Canadian economy. One concern is that Canadian businesses have relatively low levels of business research and development (R&D), despite access to some of the world's most generous R&D tax subsidies. This doesn't mean that tax credits do not stimulate R&D; indeed, research suggests they do. Rather, low business R&D appears to be roote...

• One of the most important processes for galaxy formation and evolution ! • Big questions! – When and how does star formation occur ?! – How is it related to the evolution of galaxy properties?! – What are the physical processes that drive star formation ?! • star formation occurs (at least in spirals at low z) almost exclusively associated with molecular clouds! – what is the rate at which st...

Looking at the type of groups that exist in most UK physics departments wouldn’t lead you to believe that physics has a role to play in climate change research. Yet tucked away in earth sciences, geography and the occasional physics department across the country, physicists are making their contribution. The field of climate modelling is one where a physicist’s skills are vitally important, com...

Electron transport in nanoscale structures is strongly influenced by the Coulomb interaction that gives rise to correlations in the stream of charges and leaves clear fingerprints in the fluctuations of the electrical current. A complete understanding of the underlying physical processes requires measurements of the electrical fluctuations on all time and frequency scales, but experiments have ...

Wireless sensor network (WSN) enhanced the process of monitoring many environmental phenomena such as the air pollution monitoring issue in proposed this paper. In this paper, a WSN based microcontroller equipped with gas sensors have been actively used for air quality monitoring. The design included several units mainly: Arduino Microcontroller, MQ-2 Gas Sensors, and the current regulator circ...

Stellar evolution, a fundamental bedrock of modern astrophysics, is driven by the physical processes in stellar interiors. While we understand these processes in general terms, we lack some important ingredients. Seemingly small uncertainties in the input physics of the models, e.g., the opacities or the amount of mixing and of interior rotation, have large consequences for the evolution of sta...

I discuss our current understanding of the spin states of cometary nuclei. Cometary spin influences the temporal and spatial patterns of outgassing from the nucleus (through diurnal and seasonal effects) and is in turn influenced by outgassing-driven torques. The current challenge to cometary astronomers is to quantify the interactions between the spin, the outgassing, and the resultant torques...

The current-time characteristic during high power pulsed magnetron sputtering is measured under identical conditions for seventeen different target materials. Based on physical processes such as gas rarefaction, ion-induced electron emission, and electron impact ionization, two test parameters were derived that significantly correlate with specific features of the current-time characteristic: (...

A hereditary graph property is a collection of labeled graphs, closed under isomorphism and also under the taking of induced subgraphs. Its speed is the number of graphs in the property as a function of the number of vertices in the graph. Earlier research has characterized the speeds for hereditary graph properties up to n(1+o(1))n, and described the properties that have those smaller speeds. ...
