Fractional spectral differentiation matrices based on Legendre approximation

open access: yesAdvances in Difference Equations, 2020
A simple scheme is proposed for computing N × N $N \times N$ spectral differentiation matrices of fractional order α for the case of Legendre approximation.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Model of Functional Dendritic Cell Algorithm Based on Numerical Differentiation [PDF]

open access: yesJisuanji gongcheng, 2020
The Dendritic Cell Algorithm(DCA) is an algorithm for simulating antigen presentation in the human immune system,which can divide input data into normal and abnormal data quickly and effectively.However,the existing DCA models are generally lack of clear

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Simplified analytical expressions for numerical differentiation via cycle index [PDF]

open access: yes, 2009
Based on the Lagrange interpolation to the function f[x0,⋅] for arbitrarily chosen x0 and logarithmic differentiation, we give a simple approach to analytical expressions for numerical differentiation using cycle index.

Standard and Corrected Numerical Differentiation Formulae

open access: yesCommunications in Advanced Mathematical Sciences, 2019
Standard numerical differentiation rules that might be established by the method of undetermined coefficients are revisited. Best truncation error bounds are established by a direct method and by the method of integration by parts "backwards".

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Numerical differentiation of fractional order derivatives based on inverse source problems of hyperbolic equations

open access: yesMathematical Modelling and Analysis
In this paper, we mainly study the numerical differentiation problem of computing the fractional order derivatives from noise data of a single variable function.
