Natural Design of a Stabilized Cross‐β Fold: Structure of the FuA FapC from Pseudomonas Sp. UK4 Reveals a Critical Role for Stacking of Imperfect Repeats

Advanced Materials, EarlyView.
We report a 3.2 Å cryoEM structure of functional amyloid protein FapC from Pseudomonas sp. UK4, an essential component of bacterial biofilm, which reveals a Greek key‐shaped protofilament, supports bioinformatically determined motifs, nuances AlphaFold predictions, emphasizes heterogeneous cross‐β stacking in amyloid cross‐seeding and shows strain ...

Approximation order to a function in C(R) by superposition of a sigmoidal function

Applied Mathematics Letters, 2002
Abstract We investigate the approximation error to a continuous function defined on the whole real line by superposition of a sigmoidal function. With the minimal constraints on a continuous function, we show that the approximation order by 3n superposition of a sigmoidal function is O (1/n).

Development of a Sensitive Electrochemical Aptasensor for Non‐Small Cell Lung Cancer Extracellular Vesicle Detection

Advanced Materials Interfaces, EarlyView.
A novel electrochemical aptasensor enables the selective detection of lung cancer‐derived EVs by targeting the CD44 surface marker. The sensor uses a self‐assembled monolayer (SAM) for aptamer immobilization and achieves label‐free EV detection through electrochemical impedance spectroscopy.

Parameter Estimation of Sigmoid Superpositions: Dynamical System Approach

, 2003
Superposition of sigmoid function over a finite time interval is shown to be equivalent to the linear combination of the solutions of a linearly parameterized system of logistic differential equations.
