Optimal Deployment and Operation of Robotic Aerial 6G Small Cells with Grasping End Effectors [PDF]

arXiv, 2021
Although airborne base stations (ABSs) mounted on drones show a significant potential to enhance network capacity and coverage due to their flexible deployment, the system performance is severely limited by the endurance of the on-board battery. To overcome this key shortcoming, we are exploring robotic airborne base station (RABS) with energy neutral ...

Mapping of Ras-related GTP-binding proteins by GTP overlay following two-dimensional gel electrophoresis.

Proceedings of the National Academy of Sciences of the United States of America, 1994
For identification of Rab, Rac, Rho, Ral, Rap, and Arf proteins on two-dimensional polyacrylamide gels, we have expressed full-length cDNAs of members of these protein families with the T7 RNA polymerase-recombinant vaccinia virus expression system ...

Late blight pathogen targets host Rab‐G3 GTPases with an atypical GTPase‐activating protein

Journal of Integrative Plant Biology, EarlyView.
The Phytophthora infestans RXLR effector Pi17063 functions as an atypical GTPase‐activating protein of host positive immune regulators, specifically the small GTPase NbRab‐G3. Pi17063 promotes the relocalization of NbRab‐G3 proteins to the cytoplasm, where they are inactive, disrupting the balance of the NbRab‐G3 switch and thus leading to enhanced ...

The rab3A-22A chimera prevents sperm exocytosis by stabilizing open fusion pores [PDF]

, 2016
At the final stage of exocytotis, a fusion pore opens between the plasma and a secretory vesicle membranes; typically, when the pore dilates the vesicle releases its cargo.

Robust Adaptive Beamforming Maximizing the Worst-Case SINR over Distributional Uncertainty Sets for Random INC Matrix and Signal Steering Vector [PDF]

arXiv, 2021
The robust adaptive beamforming (RAB) problem is considered via the worst-case signal-to-interference-plus-noise ratio (SINR) maximization over distributional uncertainty sets for the random interference-plus-noise covariance (INC) matrix and desired signal steering vector.

Biology of the Rap proteins, members of the ras superfamily of GTP-binding proteins.

Biochemical Journal, 1993
A large superfamily (> 50 members) of monomeric GTPbinding proteins structurally related to the ras oncogene proteins has been described in the past few years (Bourne et al., 1991; Grand and Owen, 1991; Hall, 1990; Valencia et al., 1991).

The synaptic vesicle cluster as a controller of pre‐ and postsynaptic structure and function

The Journal of Physiology, EarlyView.
Abstract figure legend The synaptic vesicle cluster acts as a master regulator of synaptic structure and function, through various involvements in processes that range from synaptic initiation to plasticity and synaptic loss. Abstract The synaptic vesicle cluster (SVC) is an essential component of chemical synapses, which provides neurotransmitter ...

A syntaxin 10-SNARE complex distinguishes two distinct transport routes from endosomes to the trans-Golgi in human cells [PDF]

, 2008
Mannose 6-phosphate receptors (MPRs) are transported from endosomes to the Golgi after delivering lysosomal enzymes to the endocytic pathway. This process requires Rab9 guanosine triphosphatase (GTPase) and the putative tether GCC185.

Intracellular Vesicle Trafficking Genes, RabC-GTP, Are Highly Expressed Under Salinity and Rapid Dehydration but Down-Regulated by Drought in Leaves of Chickpea (Cicer arietinum L.)

Frontiers in Genetics, 2019
Intracellular vesicle trafficking genes, Rab, encoding small GTP binding proteins, have been well studied in medical research, but there is little information concerning these proteins in plants.

Multiple GTP-binding proteins regulate vesicular transport from the ER to Golgi membranes

Journal of Cell Biology, 1992
Using indirect immunofluorescence we have examined the effects of reagents which inhibit the function of ras-related rab small GTP- binding proteins and heterotrimeric G alpha beta gamma proteins in ER to Golgi transport. Export from the ER was inhibited
