Receptor activity-modifying proteins (RAMPs) are a class of protein that interact with and modulate the activities of several Class B G protein-coupled receptors including the receptors for secretin, calcitonin (CT), glucagon, and vasoactive intestinal peptide (VIP). [1]
A particular RAFT agent is only suitable for a limited set of monomers and the synthesis of a RAFT agent typically requires a multistep synthetic procedure and subsequent purification. [11] RAFT agents can be unstable over long time periods, are highly colored and can have a pungent odor due to gradual decomposition of the dithioester moiety to ...
The Enders SAMP/RAMP hydrazone alkylation reaction is an asymmetric carbon-carbon bond formation reaction facilitated by pyrrolidine chiral auxiliaries. It was pioneered by E. J. Corey and Dieter Enders in 1976, [1] and was further developed by Enders and his group. [2] This method is usually a three-step sequence.
Chilean mountaineers announce that they have discovered the wreckage of LAN Chile Flight 210, a Douglas DC-3 carrying 24 people, including eight members of the Chilean football (soccer) team Club de Deportes Green Cross, which disappeared over the Andes Mountains in Chile during a domestic flight from Osorno to Santiago on 3 April 1961. The ...
The term "ramp" can also be used for other functions obtained by scaling and shifting, and the function in this article is the unit ramp function (slope 1, starting at 0). In mathematics, the ramp function is also known as the positive part. In machine learning, it is commonly known as a ReLU activation function [1] [2] or a rectifier in ...
RAMP was originally developed by Rex Thompson & Partners Ltd. in the mid-1980s as an availability simulation program, primarily used for plant and process modelling. [1] The ownership of RAMP was transferred to T.A. Group [2] upon its founding in January 1990, [3] and then to Fluor Corporation when it acquired T.A. Group in April 1996, [4 ...
Baggage handler unloading baggage from a bag belt at Detroit Metropolitan Airport. In the airline industry, a baggage handler is a person who loads and unloads baggage (suitcases or luggage), and other cargo (airfreight, mail, counter-to-counter packages) for transport via aircraft.
The delta rule is commonly stated in simplified form for a neuron with a linear activation function as = () While the delta rule is similar to the perceptron 's update rule, the derivation is different.
