Electrically Induced Phase Transition and Synaptic Functionality in MoTe2/Graphene Memristors

Advanced Functional Materials, EarlyView.
An electrically induced reversible 2H ↔ 1T′ phase transition is demonstrated in a vertical Au/Ti/MoTe2/graphene memristor with a laterally contacted graphene electrode. Resistive switching proceeds through a compositionally invariant amorphous/2H ↔ amorphous/1T′ transformation, in which a self‐formed amorphous MoTe2 interfacial region is proposed to ...

An Epigenetic Fate Converter Based on Nuclei‐Targeting Lipid Nanoparticles Drives Neuronal Programming of Stem Cells for Spinal Cord Repair

Advanced Functional Materials, EarlyView.
Schematic illustration of LNP‐MPG nuclei‐targeting delivery of HMW‐FGF2 promoting histone acetylation to regulate the fate of DPSCs and treat spinal cord injury. LNPs components include pHMW‐FGF2 plasmid, DSPC, Dlin‐MC3‐DMA, cholesterol, and PEG2000, and are modified with MPG to form HMW‐FGF2@LNP‐MPG (HLM). HLM nuclei‐targets DPSCs to deliver HMW‐FGF2,

Photo‐Switchable Molecular Module Programming PET Biodegradation in Aquatic Environments

Advanced Functional Materials, EarlyView.
We address the plastic durability paradox by integrating an itaconic acid–derived pyrrolidone module into polymer backbones. Sunlight in water triggers Norrish Type I ring‐opening and hydrophilization, enabling rapid biodegradation into nontoxic minerals.

Selection of artificial teeth

The Journal of Prosthetic Dentistry, 1967
Abstract The selection of both anterior and posterior artificial teeth for removable restorations is the responsibility of the dentist. Many of the guides that only the dentist has available to aid in selection of artificial teeth were described.

Screening and selection of artificial riboswitches

Methods, 2018
Synthetic riboswitches are engineered to regulate gene expression in response to a variety of non-endogenous small molecules, and a challenge to select this engineered response requires robust screening tools. A new synthetic riboswitch can be created by linking an in vitro-selected aptamer library with a randomized expression platform followed by in ...

Assortative mating and artificial selection

Heredity, 1973
Theory is developed to assess the consequences of assortative mating immediately following truncation selection. Truncation selection is expected to generate negative correlations between homologous genes and between non-homologous genes in the same and different gametes.

Artificial Selection Experiments

Annual Review of Ecology and Systematics, 1992
A knowledge of the magnitude of genetic variability and covariability of quantitative traits in natural populations and an understanding of the action of forces that maintain variation and those that lead to change are fundamental to the study of evolutionary biology.

Artificial Selection

2007
This chapter highlights artificial selection—the deliberate choice of certain individuals to propagate a line. This has been the mechanism for producing all the modern varieties of domestic animals and crop plants. Indeed, the application of evolutionary principles to practical problems has been essential to the great expansion of agricultural ...

Darwin’s artificial selection as an experiment

Studies in History and Philosophy of Science Part C: Studies in History and Philosophy of Biological and Biomedical Sciences, 2006
Darwin used artificial selection (ASN) extensively and variedly in his theorizing. Darwin used ASN as an analogy to natural selection; he compared artificial to natural varieties, hereditary variation in nature to that in the breeding farm; and he also compared the overall effectiveness of the two processes.

Simulated evolution and artificial selection

Biosystems, 1989
A highly simplified evolving system was investigated by computer simulation. The genetic complement of each simulated organism in the population was represented by a single chromosome that consisted of a string of symbols. Individual fitness was measured as the number of symbols that corresponded to a specified rule.
