Barrier Lyapunov Function-Based Sliding Mode Control for BWB Aircraft With Mismatched Disturbances and Output Constraints

IEEE Access, 2019
This paper presents a barrier Lyapunov function based nonsingular fast terminal sliding mode control with fixed-time non-recursive disturbance observer for the blended-wing-body (BWB) aircraft in the presence of mismatched disturbances and output ...

Global existence for a singular phase field system related to a sliding mode control problem

, 2017
In the present contribution we consider a singular phase field system located in a smooth and bounded three-dimensional domain. The entropy balance equation is perturbed by a logarithmic nonlinearity and by the presence of an additional term involving a ...

Facilitated diffusion of DNA-binding proteins [PDF]

, 2005
The diffusion-controlled limit of reaction times for site-specific DNA-binding proteins is derived from first principles. We follow the generally accepted concept that a protein propagates via two competitive modes, a three-dimensional diffusion in space

Adenosine‐to‐inosine editing of miR‐200b‐3p is associated with the progression of high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
A‐to‐I editing of miRNAs, particularly miR‐200b‐3p, contributes to HGSOC progression by enhancing cancer cell proliferation, migration and 3D growth. The edited form is linked to poorer patient survival and the identification of novel molecular targets.

Investigating the cell of origin and novel molecular targets in Merkel cell carcinoma: a historic misnomer

Molecular Oncology, EarlyView.
This study indicates that Merkel cell carcinoma (MCC) does not originate from Merkel cells, and identifies gene, protein & cellular expression of immune‐linked and neuroendocrine markers in primary and metastatic Merkel cell carcinoma (MCC) tumor samples, linked to Merkel cell polyomavirus (MCPyV) status, with enrichment of B‐cell and other immune cell

A study on variable gain sliding mode fixed-time strategy for aircraft electromechanical actuators

Xibei Gongye Daxue Xuebao
To improve the convergence speed of angular velocity tracking error, and reduce the input energy consumption of aircraft comprehensive control, a variable gain sliding mode fixed-time control method is proposed.

Adaptive Super-Twisting Cooperative Guidance Law with Fixed-Time Convergence

International Journal of Aerospace Engineering, 2022
For the guidance problem of multiple missiles cooperatively intercepting a maneuvering target, fixed-time cooperative guidance law is proposed with impact angle constraints. First, fixed-time consensus, integral sliding mode technique, and adaptive super-

Integrated genomic and proteomic profiling reveals insights into chemoradiation resistance in cervical cancer

Molecular Oncology, EarlyView.
A comprehensive genomic and proteomic analysis of cervical cancer revealed STK11 and STX3 as a potential biomarkers of chemoradiation resistance. Our study demonstrated EGFR as a therapeutic target, paving the way for precision strategies to overcome treatment failure and the DNA repair pathway as a critical mechanism of resistance.
