On the Parametrization of Flavor Mixing in the Standard Model [PDF]
, 1997 It is shown that there exist nine different ways to describe the flavor mixing, in terms of three rotation angles and one CP-violating phase, within the standard electroweak theory of six quarks.

Study of Water-cooled Auto-cascade Refrigeration Cycle with a Low Temperature of﹣60 ℃
Zhileng xuebao, 2015 A new water-cooled auto-cascade refrigeration cycle(WACR) using a binary refrigerant mixture is presented, which adopts a condenser-phase separator instead of a condenser and an evaporative separator in traditional auto-cascade refrigeration cycle.

Emission Line Abundances of Absorption Selected Galaxies at z<0.5
, 2004 We have obtained optical spectra of four galaxies associated with MgII QSO absorbers at redshifts 0.10 < z < 0.45. We calculate the gas-phase oxygen abundance of these galaxies using the empirical R23 strong line method. The absolute B-band magnitudes of

Infectious disease, human capital, and the BRICS economy in the time of COVID-19
MethodsX, 2021 We develop empirical models using difference-in-difference method to find out how COVID-19 testing and infection rates impact the BRICS economy. Our results show that strict government measures, areas of poor people and people with heart diseases have ...

Internal Variations in Empirical Oxygen Abundances for Giant HII Regions in the Galaxy NGC 2403
, 2018 This paper presents a spectroscopic investigation of 11 HII regions in the nearby galaxy NGC 2403. The HII regions are observed with a long-slit spectrograph mounted on the 2.16 m telescope at XingLong station of National Astronomical Observatories of ...

The DEEP2 Galaxy Redshift Survey: Discovery of Luminous, Metal-poor, Sta r-forming Galaxies at Redshifts z~0.7 [PDF]
, 2005 We have discovered a sample of 17 metal-poor, yet luminous, star-forming galaxies at redshifts z~0.7. They were selected from the initial phase of the DEEP2 survey of 3900 galaxies and the Team Keck Redshift Survey (TKRS) of 1536 galaxies as those ...

Use of Constraints in the Hierarchical Aggregation Procedure Intramax
Business Systems Research, 2016 Background: Intramax is a hierarchical aggregation procedure for dealing with the multi-level specification problem and with the association issue of data set reduction, but it was used as a functional regionalization procedure many times in the past.
