The protein negatively regulates the initiation of DNA replication at the origin of replication, in Escherichia coli, OriC. Additionally the protein plays a further role in seques... |
https://en.wikipedia.org/wiki/PICO%20process | The PICO process (or framework) is a mnemonic used in evidence-based practice (and specifically evidence-based medicine) to frame and answer a clinical or health care related question, though it is also argued that PICO "can be used universally for every scientific endeavour in any discipline with all study designs". T... |
https://en.wikipedia.org/wiki/Molecular%20modeling%20on%20GPUs | Molecular modeling on GPU is the technique of using a graphics processing unit (GPU) for molecular simulations.
In 2007, NVIDIA introduced video cards that could be used not only to show graphics but also for scientific calculations. These cards include many arithmetic units (, up to 3,584 in Tesla P100) working in pa... |
https://en.wikipedia.org/wiki/International%20Knockout%20Mouse%20Consortium | The International Knockout Mouse Consortium (IKMC) is a scientific endeavour to produce a collection of mouse embryonic stem cell lines that together lack every gene in the genome, and then to distribute the cells to scientific researchers to create knockout mice to study. Many of the targeted alleles are designed so t... |

https://en.wikipedia.org/wiki/Road%20ecology | Road ecology is the study of the ecological effects (both positive and negative) of roads and highways (public roads). These effects may include local effects, such as on noise, water pollution, habitat destruction/disturbance and local air quality; and the wider environmental effects of transport such as habitat fragm... |
https://en.wikipedia.org/wiki/Digital%20Postmarks | A Digital Postmark (DPM) is a technology that applies a trusted time stamp issued by a postal operator to an electronic document, validates electronic signatures, and stores and archives all non-repudiation data needed to support a potential court challenge. It guarantees the certainty of date and time of the postmarki... |
https://en.wikipedia.org/wiki/Relict%20%28biology%29 | In biogeography and paleontology, a relict is a population or taxon of organisms that was more widespread or more diverse in the past. A relictual population is a population currently inhabiting a restricted area whose range was far wider during a previous geologic epoch. Similarly, a relictual taxon is a taxon (e.g. s... |
https://en.wikipedia.org/wiki/Mach%27s%20principle | In theoretical physics, particularly in discussions of gravitation theories, Mach's principle (or Mach's conjecture) is the name given by Albert Einstein to an imprecise hypothesis often credited to the physicist and philosopher Ernst Mach. The hypothesis attempted to explain how rotating objects, such as gyroscopes a... |
https://en.wikipedia.org/wiki/Enterprise%20appliance%20transaction%20module | An enterprise appliance transaction module (EATM) is a device, typically used in the manufacturing automation marketplace, for the transfer of plant floor equipment and product status to manufacturing execution systems (MES), enterprise resource planning (ERP) systems and the like.

https://en.wikipedia.org/wiki/Neuroligin | Neuroligin (NLGN), a type I membrane protein, is a cell adhesion protein on the postsynaptic membrane that mediates the formation and maintenance of synapses between neurons. Neuroligins act as ligands for β-neurexins, which are cell adhesion proteins located presynaptically. Neuroligin and β-neurexin "shake hands", re... |
