Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Robustness of Device Independent Dimension Witnesses

open access: yes, 2012
Device independent dimension witnesses provide a lower bound on the dimensionality of classical and quantum systems in a "black box" scenario where only correlations between preparations, measurements and outcomes are considered.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Portfolio Implementation Risk Management Using Evolutionary Multiobjective Optimization

open access: yesApplied Sciences, 2017
Portfolio management based on mean-variance portfolio optimization is subject to different sources of uncertainty. In addition to those related to the quality of parameter estimates used in the optimization process, investors face a portfolio ...

Developmental Evolution: Getting Robust About Robustness [PDF]

open access: yesCurrent Biology, 2002
In the context of development, a process is robust if it can proceed normally despite the enormous capacity for perturbation inherent in all biological systems. A new mode of theoretical modeling of genetic networks holds great promise for increasing our understanding of both the quantitative mechanisms of robustness and its evolutionary impact.

SWEEPFINDER2: Increased sensitivity, robustness, and flexibility

open access: yes, 2015
SweepFinder is a popular program that implements a powerful likelihood-based method for detecting recent positive selection, or selective sweeps. Here, we present SweepFinder2, an extension of SweepFinder with increased sensitivity and robustness to the ...

Function‐driven design of a surrogate interleukin‐2 receptor ligand

open access: yesFEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

Analytical performance of an inductively coupled plasma optical emission spectrometry with Dual View configuration

open access: yesJournal of the Brazilian Chemical Society, 2003
The analytical performance of axially and radially viewed inductively coupled plasma optical emission spectrometers (AX-ICP OES and RD-ICP OES, respectively) were evaluated in terms of the Mg II/Mg I ratio, matrix effects, and detection limits (LOD). All

Research of PMSM-DTC system based on the super-twisting second sliding mode control

open access: yesJournal of Hebei University of Science and Technology, 2017
Aiming at the problems that the conventional permanent magnet synchronous motor direct torque control system (PMSM-DTC) is susceptible to the influence of parameter change and torque ripple, it is proposed that the space voltage vector modulation ...
