Toward Design Principles for Biomolecular Condensates for Metabolic Pathways

open access: yesAdvanced Biology, EarlyView.
Biomolecular condensates are membrane‐less compartments found through‐out nature which can serve as reaction crucibles for biochemical processes. This review explores the design strategies underlying how condensates can be used in biotechnology to enhance multistep enzyme cascades including enhancement by mass action and substrate channeling, and ...

Orbit prediction and Earth shadow modeling for Chandrayaan-2 Orbiter

Astrophysics and Space Science, 2021
Chandrayaan-2, India’s second Moon mission, comprised of Orbiter, Lander and Rover modules was launched on July 22, 2019. The Chandrayaan-2 (CH2) Orbiter, which carries eight scientific payloads, is placed into a circular lunar orbit of 100 km altitude with an orbital period of around 120 minutes. After the successful injection of the spacecraft in the

An analytic orbit prediction program generator [PDF]

open access: possibleJournal of Guidance, Control, and Dynamics, 1983
An ephemeris program generator is designed to automatically construct compact efficient ephemeris programs tailored specifically for tasks encountered in online real-time computing environments. For portability the ephemeris programs are written in standard FORTRAN IV.

Sensitivity of Orbit Predictions to Density Variability [PDF]

open access: possibleJournal of Spacecraft and Rockets, 2008
This paper summarizes the first stage in a research effort designed to obtain a quantitative knowledge and deeper understanding of how prediction error depends on density variability. Initial numerical simulations are performed to obtain a detailed understanding of the theoretical effects of density variations on satellite orbit predictions.

Nimerical Averaging in Orbit Prediction [PDF]

open access: possibleAIAA Journal, 1972
This paper is a presentation of some useful aspects of a numerical averaging technique that has been applied with considerable success to the orbit prediction problem for artificial satellites. The method has been tested in a variety of situations wherein the satellite is subjected to combinations of perturbations for which adequate analytic theories ...
