The Reproducibility Project is a series of crowdsourced collaborations aiming to reproduce published scientific studies, finding high rates of results which could not be replicated. It has resulted in two major initiatives focusing on the fields of psychology [ 1 ] and cancer biology. [ 2 ]
However, their funding bodies may require them to publish in scientific journals. The paper is submitted to the journal office, where the editor considers the paper for appropriateness, potential scientific impact and novelty. If the journal's editor considers the paper appropriate, the paper is submitted to scholarly peer review. Depending on ...
In line with qualitative accounts of J-PAL's influence in popularizing experimental research methods, [5] [6] a paper by Janet Currie and co-authors in the papers and proceedings of the American Economic Association observed that the share of NBER working papers leveraging randomized controlled trials increased from less than 5% to almost 15% ...
Content usually takes the form of articles presenting original research, review articles, or book reviews.The purpose of an academic journal, according to Henry Oldenburg (the first editor of Philosophical Transactions of the Royal Society), is to give researchers a venue to "impart their knowledge to one another, and contribute what they can to the Grand design of improving natural knowledge ...
The cell cycle is a four-stage process that a cell goes through as it develops and divides. It includes Gap 1 (G1), synthesis (S), Gap 2 (G2), and mitosis (M). The cell either restarts the cycle from G1 or leaves the cycle through G0 after completing the cycle. The cell can progress from G0 through terminal differentiation.
The eukaryotic cell cycle consists of four distinct phases: G 1 phase, S phase (synthesis), G 2 phase (collectively known as interphase) and M phase (mitosis and cytokinesis). M phase is itself composed of two tightly coupled processes: mitosis, in which the cell's nucleus divides, and cytokinesis, in which the cell's cytoplasm and cell membrane divides forming two daughter cells.
Autocrine signaling occurs when the chemical signal acts on the same cell that produced the signaling chemical. [1] Intracrine signaling occurs when the chemical signal produced by a cell acts on receptors located in the cytoplasm or nucleus of the same cell. [2] Juxtacrine signaling occurs between physically adjacent cells. [3]
[1] [2] [3] The concept of self-replicating machines has been advanced and examined by Homer Jacobson, Edward F. Moore, Freeman Dyson, John von Neumann, Konrad Zuse [4] [5] and in more recent times by K. Eric Drexler in his book on nanotechnology, Engines of Creation (coining the term clanking replicator for such machines) and by Robert Freitas ...
