Engineered Protein‐Based Ionic Conductors for Sustainable Energy Storage Applications
Rational incorporation of charged residues into an engineered, self‐assembling protein scaffold yields solid‐state protein films with outstanding ionic conductivity. Salt‐doping further enhances conductivity, an effect amplified in the engineered variants. These properties enable the material integration into an efficient supercapacitor.

Bottom‐Up Programming of Cell States in Cancer Organoids with Defined Synthetic Adhesion Cues
A bottom‐up biomaterial platform is developed to program transcriptomic states in pancreatic cancer organoids by tuning adhesion cues within synthetic matrices. By combining a Design of Experiments framework with multiobjective optimization, matrix compositions are identified that enrich specific cellular programs like EMT.

Reflections on the clonal-selection theory
Nature Reviews Immunology, 2007How do we account for the immune system's ability to produce antibodies in response to new antigens? It has been 50 years since F. Macfarlane Burnet published his answer to this question: the clonal-selection theory of antibody diversity. The idea that specificity for diverse antigens exists before these antigens are encountered was a radical notion at

CLONAL SELECTION OF 'SANGIOVESE' IN TOSCANY
Acta Horticulturae, 2004Clonal selection was carried out in the coastal area of Tuscany, with special reference to the ‘Morellino di Scansano’ DOC area (province of Grosseto), according to the procedures specified by the National Committee for the homologation of grapevine material.

Immune Clonal Selection Network
2004Based on the Antibody Clonal Selection Theory of immunology, the general steps of ICSA (Immune Clonal Selection Algorithm) are presented in this paper The network framework of ICSA is put forward, and the dynamic characters of ICSA are analyzed based on the Lyapunov theory Then, this paper gives a novel Artificial Immune System Algorithm, Pseudo- Grads

Differential immune clonal selection algorithm
2007 International Symposium on Intelligent Signal Processing and Communication Systems, 2007Based on the antibody clonal selection theory of immunology and differential evolution paradigm, we put forward a novel artificial immune system algorithm, differential immune clonal selection algorithm, termed as DICSA. The DICSA evolves and improves the population by clonal proliferation operator, differential mutation operator, differential ...

Habitat Selection in a Clonal Plant
Science, 1985Rhizomatous growth may permit the nonrandom placement of ramets into different environments, but whether clonal plants are able to use this means to exercise adaptive habitat choice is not known. Western ragweed (Ambrosia psilostachya) plants are shown to preferentially colonize nonsaline soil over saline soil patches, and clones with the strongest ...

Clonal Selection and After, and After
New England Journal of Medicine, 1979The central feature of the immune system is that it usually manages to distinguish precisely between normal tissue of the body and foreign material.
