Pedestrian navigation: how can inertial measurment units assist smartphones?

open access: yesРоссийский технологический журнал, 2021
This paper is devoted to construction of reference walking trajectories for developing pedestrian navigation algorithms for smartphones. Such trajectories can be used both for verification of classical algorithms of navigation or for application of ...

Interactions between Type III receptor tyrosine phosphatases and growth factor receptor tyrosine kinases regulate tracheal tube formation in Drosophila [PDF]

open access: yes, 2012
The respiratory (tracheal) system of the Drosophila melanogaster larva is an intricate branched network of air-filled tubes. Its developmental logic is similar in some ways to that of the vertebrate vascular system.

Below the Surface: IGF-1R Therapeutic Targeting and Its Endocytic Journey

open access: yesCells, 2019
Ligand-activated plasma membrane receptors follow pathways of endocytosis through the endosomal sorting apparatus. Receptors cluster in clathrin-coated pits that bud inwards and enter the cell as clathrin-coated vesicles.

An Effective Multi-Cue Positioning System for Agricultural Robotics [PDF]

open access: yes, 2018
The self-localization capability is a crucial component for Unmanned Ground Vehicles (UGV) in farming applications. Approaches based solely on visual cues or on low-cost GPS are easily prone to fail in such scenarios.

Static Positioning under Tree Canopy Using Low-Cost GNSS Receivers and Adapted RTKLIB Software

open access: yesSensors, 2023
The decrease in costs and dimensions of GNSS receivers has enabled their adoption for a very wide range of users. Formerly mediocre positioning performance is benefiting from recent technology advances, namely the adoption of multi-constellation, multi ...

An In-Vehicle Smartphone RTK/DR Positioning Method Combined with OSM Road Network

open access: yesRemote Sensing, 2023
In vehicle navigation scenarios, the RTK positioning results of smartphones are prone to jumps due to the interference of complex urban environments, and the heading angle of dead reckoning (DR) is prone to divergence.

Morphological updating on the basis of integrated DTMs: study on the Albano and Nemi craters [PDF]

open access: yes, 2008
The Colli Albani Volcano has recently developed particular interest in the geophysical community for some peculiar characteristics imputable to a recent residual volcanic activity, thus evidencing that it cannot be considered extinguished yet.

Parsimony and complexity: Cell fate assignment in the developing Drosophila eye

open access: yesFly, 2017
The specification of the R7 photoreceptor in the Drosophila eye has become a classic model for understanding how cell fates are assigned in developing systems.

JUN dependency in distinct early and late BRAF inhibition adaptation states of melanoma. [PDF]

open access: yes, 2016
A prominent mechanism of acquired resistance to BRAF inhibitors in BRAF (V600) -mutant melanoma is associated with the upregulation of receptor tyrosine kinases.

FAK acts as a suppressor of RTK-MAP kinase signalling in Drosophila melanogaster epithelia and human cancer cells [PDF]

open access: yes, 2014
Receptor Tyrosine Kinases (RTKs) and Focal Adhesion Kinase (FAK) regulate multiple signalling pathways, including mitogen-activated protein (MAP) kinase pathway. FAK interacts with several RTKs but little is known about how FAK regulates their downstream
