G protein coupling and activation of the metabotropic GABAB heterodimer

open access: yesNature Communications, 2022
Despite its crucial role in the central nervous system, little is known about the activation mechanism of GABAB receptor. Here, the authors predict that the inactive G protein induces conformational changes of the receptor to form an intermediate state.

Predicted structure of fully activated human bitter taste receptor TAS2R4 complexed with G protein and agonists

open access: yesQRB Discovery, 2021
Bitter taste is sensed by bitter taste receptors (TAS2Rs) that belong to the G protein-coupled receptor (GPCR) superfamily. In addition to bitter taste perception, TAS2Rs have been reported recently to be expressed in many extraoral tissues and are now ...

Applying the simulation process [PDF]

open access: yes1988 Winter Simulation Conference Proceedings, 1987
The purpose of this tutorial is to explain the steps required in conducting an entire simulation project. We first explain the twelve steps we consider necessary to accomplish a thorough simulation study. Then we describe three projects that the authors have completed. We discuss the systems, model assumptions, and input data for these projects. During

Software process simulation—at a crossroads? [PDF]

open access: yesJournal of Software: Evolution and Process, 2014
ABSTRACTSoftware process simulation (SPS) has been evolving over the past two decades after being introduced to the software engineering community in the 1980s. At that time the SPS technology attracted a great deal of interest from both academics and practitioners in the software process community—even to the extent of being one of the recommended ...
