The XMASS experiment

Search for bosonic superweakly interacting massive dark matter particles with the XMASS-I detector.

Bosonic superweakly interacting massive particles (super-WIMPs) are a candidate for warm dark matter. With the absorption of such a boson by a xenon atom, these dark matter candidates would deposit an energy equivalent to their rest mass in the detector. This is the first direct detection experiment exploring the vector super-WIMPs in the mass range between 40 and 120 keV. With the use of 165.9...

The Effect of Experiment Range of Control Variables on the Efficiency of Regression Modeling

The efficient planning of each system requires an understanding of the true nature of the system. Regression models also represent a system that its input variables, the role of the system input, its variables coefficients, the role of the system process, and its response variables, play the role of the system output. Therefore, for exact regression modeling and efficient planning, it's essenti...

An Introduction to Natural Experiment Studies

در دو سخن سردبیری شماره‌های قبل به مطالعات مداخله‌ای (Interventional and/or experimental studies) [1] و مطالعات نیمه تجربی (studies Quasi-experiment) [2] پرداختیم. همان جا، به این نکته اشاره کردیم که برای اندازه‌گیری کارآیی یک دارو، واکسن، برنامه بهداشت عمومی و متغیرهای دیگری از این دست، مطالعات مداخله‌ای بهترین گزینه هستند. تقسیم تصادفی و کورسازی از مؤلفه‌های اساسی یک مطالعه مداخله‌ای است [1]....
