Rest Frame Subjet Algorithm With SISCone Jet For Fully Hadronic Decaying Higgs Search

The rest frame subjet algorithm is introduced to define the subjets for the SISCone jet. Using it, an IR and collinear safe jet shape observable N-subjettiness, $\tau_N^{j}$, is defined to discriminate the fat jet from a highly boosted color singlet particle decaying to N partons and the QCD jet. Using rest frame subjets and $\tau_2^{j}$ on dijets from highly boosted $\it H / W / Z$ bosons through $pp \to \it H W$, $\it H Z$, we found that statistical significance of the signal is about $2 \sigma$ at the LHC with $\mathcal{L} \sim 30 \mathrm{fb^{-1}}$ at 14 \tev.Comment: 5 pages, 3 figures. v2: references added, minor corrections.

How to Compare the Scientific Contributions between Research Groups

We present a method to analyse the scientific contributions between research groups. Given multiple research groups, we construct their journal/proceeding graphs and then compute the similarity/gap between them using network analysis. This analysis can be used for measuring similarity/gap of the topics/qualities between research groups' scientific contributions. We demonstrate the practicality of our method by comparing the scientific contributions by Korean researchers with those by the global researchers for information security in 2006 - 2008. The empirical analysis shows that the current security research in South Korea has been isolated from the global research trend

Intraocular Pressure Fluctuation: Is It Important?

Elevated intraocular pressure (IOP) is a major risk factor for the development and progression of glaucoma. Previous prospective, randomized, long-term studies have demonstrated the strength of IOP reduction in slowing the progression of disease. It is well known that IOP is not a fixed value but fluctuates considerably over time. Although there have been some studies on IOP fluctuation and the progression of glaucoma, whether IOP fluctuation is an independent risk factor for glaucomatous damage and disease progression remains controversial. In this article, we reviewed the definition of IOP fluctuation, and both the evidence and the speculation for and against the effect of IOP fluctuation on glaucoma progression. Although conclusions seem to vary from study to study, we considered that different studies examined different groups of patients, at different stages of disease, and at different IOP levels. Our conclusion is that these apparently disparate results are not conflicting, but rather can be viewed as complementary. In clinical care, we recommend the consideration of IOP "modulation" rather than just IOP "reduction" when glaucoma patients are treated. Quality-based IOP control may be more effective than quantity-based IOP reduction to prevent or retard disease progression
