Absolute stability of switched lurie systems
Applied Mathematics in Science and EngineeringThis paper investigates the absolute stability problem of switched Lurie systems. Based on two new switched time-varying Lyapunov-Lurie functions, sufficient conditions for the absolute stability of the switched Lurie systems are provided under the ...

On an Application of the Absolute Stability Theory to Sampled-Data Stabilization [PDF]
Mathematical Problems in Engineering, 2018 A nonlinear Lur’e-type plant with a sector bound nonlinearity is considered. The plant is stabilized by a discrete-time feedback signal with a nonperiodic uncertain sampling. The sampling control function is nonlinear and also obeys some sectoral constraints at discrete (sampling) times.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry
FEBS Letters, EarlyView.EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

FINANCIAL STABILITY CROSS-REFERENCE BASED ON CALCULATION OF ABSOLUTE INDICATORS [PDF]
Economica, 2017 The lack of applied methods in the national practice that would allow the realization of a complex analysis of financial stability in the corporate sector is one of the primary problems outlined in the process of organizing the fair and efficient ...

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

FEBS Letters, EarlyView.How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Absolute Stability of a Class of Nonlinear Singular Systems with Time Delay
Abstract and Applied Analysis, 2014 This paper deals with the absolute stability for a class of nonlinear singular systems with time delay. By employing a new Lyapunov-Krasovskii functional with the idea of partitioning delay length, improved delay-dependent stability criteria are ...

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers
FEBS Letters, EarlyView.Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

STUDIES AND APPLICATIONS OF ABSOLUTE STABILITY OF THE NONLINEAR DYNAMICAL SYSTEMS [PDF]
Annals: Series on engineering sciences (Academy of Romanian Scientists), 2013 In this paper there are presented methods of study for the automatic regulation of the absolute stability in case of the nonlinear dynamical systems. There are specified two methods for the absolute stability with criteria and mode of application: a) the

Molecular Oncology, EarlyView.Circulating microRNAs as biomarkers of cachexia and sex‐specific cancer in senior dogs. In 25 client‐owned dogs, four circulating miRNAs (miR‐15a, miR‐15b, miR‐16, miR‐140) were downregulated in cachexia, with miR‐16 the strongest individual biomarker (AUC = 0.899).
