Cerebral microdialysis is a sampling technique which offers much potential for understanding inflammatory pathophysiology following traumatic brain injury (TBI). At present, the recovery of cytokines via microdialysis in clinical studies is not straightforward primarily due to their size, steric properties and low concentrations. Heparin and heparin-coated microspheres have previously shown pro...

We propose a hypothesis that differences in base excision repair capacity modulate the effect of dietary antioxidant intake on prostate cancer risk. As a preliminary test of this hypothesis, we conducted a pilot case-control study to evaluate prostate cancer risk in men with polymorphisms in the XRCC1 gene, a key player in base excision repair, across different strata of antioxidant intake. Sev...

In this lecture, we first complete the analysis of “Greedy” approach we introduced in the last lecture, that gives a constant (6)-approximation polynomial-time solution for the Uncapacitated Facility Location problem. Then, we present a primal-dual approach of solving the problem, that yields a better approximation solution of cost within a factor of 3 of the optimal. The latter has a polynomia...

We investigated the feasibility of crowdsourcing fullfledged tutorial videos from ordinary people on the Web on how to solve math problems related to logarithms. This kind of approach (a form of learnersourcing [10, 12]) to efficiently collecting tutorial videos and other learning resources could be useful for realizing personalized learning-at-scale, whereby students receive specific learning ...

Where Z∗ is OPT, we know Z∗ = 3x1 + 2x ∗ 2 + 8x ∗ 3, for some x ∗ 1, x ∗ 2, x ∗ 3 ∈ P . By adding two of the inequalities, we arrive at 2x1 + x2 + x3 ≥ 15. Since x1, x2, x3 ≥ 0, we know that Z∗ ≥ 15. But we aren’t limited to addition, multiplication is another way the equations can be combined. So how is this new formulation bouned? This is done by using the dual formulation, D of the minimizat...
