Artificial Neural Networks [PDF]
, 2017 Artificial Neural Network is a mathematical model, made in the form of software or hardware, built on the principle of biological neural networks of living cells. The neural network is a system of connected processors interacting with each other.

Artificial Stem Cell Niches [PDF]
Advanced Materials, 2009 AbstractStem cells are characterized by their dual ability to reproduce themselves (self‐renew) and specialize (differentiate), yielding a plethora of daughter cells that maintain and regenerate tissues. In contrast to their embryonic counterparts, adult stem cells retain their unique functions only if they are in intimate contact with an instructive ...

Recognition of viral glycoproteins by influenza A-specific cross- reactive cytolytic T lymphocytes [PDF]
, 1980 Two populations of cytolytic T lymphocytes (CTL) generated after influenza A virus infection can be distinguished into one with specificity for the sensitizing hemagglutinin type and a second with cross-reactivity for antigens induced by other type-A ...

An Immune Inspired Approach to Anomaly Detection [PDF]
, 2007 The immune system provides a rich metaphor for computer security: anomaly detection that works in nature should work for machines. However, early artificial immune system approaches for computer security had only limited success.

In Vitro Reassembly of the Malolactic Fermentation Pathway of Leuconostoc oenos (Oenococcus oeni) [PDF]
, 1996 The mechanism of metabolic energy generation by malolactic fermentation was studied with artificial membrane vesicles of Leuconostoc oenos (Oenococcus oeni). (Note that although L. oenos was recently reclassified as O.

Mitochondria Encapsulation in Hydrogel-Based Artificial Cells as ATP Producing Subunits.
Small, 2021 Artificial cells (ACs) aim to mimic selected structural and functional features of mammalian cells. In this context, energy generation is an important challenge to be addressed when self-sustained systems are desired.

The Evolution of complexity in self-maintaining cellular information processing networks [PDF]
, 2011 We examine the role of self-maintenance (collective autocatalysis) in the evolution of computational biochemical networks. In primitive proto-cells (lacking separate genetic machinery) self-maintenance is a necessary condition for the direct reproduction
