The polyproline site in hinge 2 influences the functional capacity of truncated dystrophins. [PDF]

open access: yesPLoS Genetics, 2010
Mutations in dystrophin can lead to Duchenne muscular dystrophy or the more mild form of the disease, Becker muscular dystrophy. The hinge 3 region in the rod domain of dystrophin is particularly prone to deletion mutations. In-frame deletions of hinge 3

Quark Mass Hierarchies, Flavor Mixing and Maximal CP-Violation [PDF]

open access: yes, 1998
Flavor mixing and the quark mass spectrum are intimately related. In view of the observed strong hierarchy of the quark and lepton masses and of the flavor mixing angles it is argued that the description of flavor mixing must take this into account.

Study of Water-cooled Auto-cascade Refrigeration Cycle with a Low Temperature of﹣60 ℃

open access: yesZhileng 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.

Infectious disease, human capital, and the BRICS economy in the time of COVID-19

open access: yesMethodsX, 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 ...

Emission Line Abundances of Absorption Selected Galaxies at z<0.5

open access: yes, 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

Thermodynamic Evaluation of Low-GWP A1 Refrigerants for Ultra-Low Temperature Refrigeration Applications

open access: yesEnergies
Slow market development has caused the lack of low-GWP A1 refrigerants for ultra-low temperature (ULT) refrigeration. Consequently, the high-GWP refrigerant R23 (GWP = 14,600) remains widely used within the ULT sector.

Youth Labour Market in Romania’s Development Regions in the Framework of Sustainable Development and of a Knowledge-based Economy

open access: yesStudia Universitatis Vasile Goldis Arad, Seria Stiinte Economice, 2017
Even if the issue of youths’ inclusion in the labour market was always an important item on political agendas, during the last two decades this issue had particular relevance. In the last years, unemployment for this age group had unprecedented amplitude,

The bends in the slopes of radial abundance gradients in the disks of spiral galaxies -- do they exist? [PDF]

open access: yes, 2002
Spiral galaxies with a reported bend in the slope of gradient in the oxygen abundances (O/H)_R23, derived with traditionally used R23 - method, were examined. It is shown that the artificial origin of the reported bends can be naturally explained.

Use of Constraints in the Hierarchical Aggregation Procedure Intramax

open access: yesBusiness 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.
