FEBS Open Bio, EarlyView.Human ABCE1 cannot functionally replace its yeast ortholog. Yeast–human chimera analysis identified NBD1 as a major interspecies barrier. Genetic screening yielded hABCE1 revertants that rescue yeast viability but fail to suppress aberrant translation reinitiation in the 3′ UTR.

A Novel Method of Estimating Induction Motor q-axis Leakage Inductance
Kongzhi Yu Xinxi Jishu, 2010 The q-axis leakage inductance Ls is always used in the control of induction motor. The parameters generally come from the analysis and calculation of the magnetic field or magnetic path, so some errors are hard to avoid.

FEBS Open Bio, EarlyView.This minireview explores fluorination as a key strategy to optimize therapeutic molecules and nanocarriers. By incorporating different fluorinated motifs—from single atoms to linear and branched chains—drug delivery, cellular uptake, and colloidal stability can be improved and fine‐tuned.

Microwave Kinetic Inductance Detectors [PDF]
, 2005 Low temperature detectors have been a subject of intense interest to the scientific community over the last decade. These detectors work at very low temperatures, often well below 1 Kelvin, to minimize the noise in the measurement of photons.

A Computationally Efficient Hybrid Leakage Model for Modeling Leakage in Positive Displacement Compressors [PDF]
, 2012 An empirical frictional correction factor to the isentropic nozzle model has been developed for application to leakage modeling in scroll, rotary and other similar compressors. This correction factor is derived by calculating the leakage mass flow with a
