A Simplified Method for Predicting the Stability of Aerodynamically Excited Turbomachinery [PDF]

open access: yes, 1991
A method is presented for the quick and accurate prediction of the stability of aerodynamically excited turbomachinery using real eigenvalue/eigenvector data obtained from a rotordynamics model.

Fidelity of holonomic quantum computations in the case of random errors in the values of control parameters

open access: yes, 2006
We investigate the influence of random errors in external control parameters on the stability of holonomic quantum computation in the case of arbitrary loops and adiabatic connections.

Aggressive prostate cancer is associated with pericyte dysfunction

open access: yesMolecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).

The neural crest‐associated gene ERRFI1 is involved in melanoma progression and resistance toward targeted therapy

open access: yesMolecular Oncology, EarlyView.
ERRFI1, a neural crest (NC)‐associated gene, was upregulated in melanoma and negatively correlated with the expression of melanocytic differentiation markers and the susceptibility of melanoma cells toward BRAF inhibitors (BRAFi). Knocking down ERRFI1 significantly increased the sensitivity of melanoma cells to BRAFi.

Design of a fractional control using performance contours. Application to an electromechanical system [PDF]

open access: yes, 2003
The article proposes a frequency-based method to design a controller ensuring dynamic behavior of a closed-loop control: the first overshoot of the step response in the tracking mode or in the regulation mode, the damping ratio and the natural frequency ...

Semantic stability within English idiomatic expressions

open access: yes, 2021
The aim of this thesis is to address a gap in historical semantics concerning idiomatic expressions by testing the hypothesis that an idiom can change its meaning over time while retaining its initial form. The linguistic literature so far has been focused on semantic change in words, on diachronic patterns according to which a lexeme changes, and on ...

Levels and Stability of Expression of Transgenes

open access: yes, 2010
It is well known that in a given cell, at a particular time, only a fraction of the entire genome is expressed. Expression of a gene, nuclear, or organellar starts with the onset of transcription and ends in the synthesis of the functional protein.

Enhancement of exogenous protein stability in AcMNPV by overexpressing lef5 gene during passaging

open access: yesApplied Microbiology and Biotechnology
The baculovirus insect cell expression system is pivotal for exogenous protein expression. However, serial passages of baculovirus in insect cells often result in defective virus generation and a rapid decline in exogenous protein expression, limiting ...
