Three-jet event-shape distributions can be exploited to investigate the dependence of hadronisation effects on the colour and the geometry of the underlying hard event. We present here the first comparison of data in ee annihilation and state-of-the-art theoretical predictions, including resummation of large logarithms at next-to-leading logarithmic accuracy matched to exact next-to-leading ord...
In this paper, we develop new bounds for the first order Marcum Q-function, which are extremely tight and tighter than any of the existing bounds to the best of our knowledge. The key idea of our approach is to derive refined approximations for the 0 order modified Bessel function in the integration region of the Marcum Q-function. The new bounds are very tight and can serve as an effective mea...
در این رساله یک ساختار از چندجمله ایهای q- هرمیت جدید را همراه با یک مشخصه بندی کامل از ویژگی های اصلی آن ارائه داده و سپس جبر عملگرهای بالابرنده و پایین آورنده متناظر با آن را استخراج می کنیم. سپس خانواده دیگری از چندجمله ایهای q- هرمیت را که با (h_n (x,s?q نشان داده می¬شوند، معرفی می نماییم و ویژگی های مهم این چندجمله ایها را مورد بررسی قرار می دهیم. همچنین یک خانواده دیگر از چندجمله ایهای هر...
Privately informed individuals speak openly in front of other members of a committee about the desirability of a public decision. Each individual wishes to appear well informed. For any given order of speech, committee members may herd by suppressing their true information. With individuals of heterogeneous expertise, optimizing over the order of speech can improve the extraction of information...
Aggregate answer ratings serve as a metric of collective intelligence in social Q&A communities. The patterns by which participants in a social Q&A community rate and recommend answers are analyzed through the lens of first-mover advantage, to address the question of whether the first answer posted has a ratings advantage over those subsequently submitted. As part of a long-term participant obs...
We describe the first two reported cases of Q fever endocarditis in Thailand. Both patients were male, had pre-existing heart valve damage and had contact with cattle. Heightened awareness of Q fever could improve diagnosis and case management and stimulate efforts to identify risk factors and preventive measures.
