Transit navigation through Northern Sea Route from satellite data and CMIP5 simulations [PDF]

Environmental Research Letters, 2017
Rapid Arctic sea ice decline over the last few decades opens new perspectives for Arctic marine navigation. Further warming in the Arctic will promote the Northern Sea Route (NSR) as an alternative to the conventional Suez or Panama Canal routes for ...

Revisiting the Transit Timing and Atmosphere Characterization of the Neptune-mass Planet HAT-P-26 b [PDF]

The Astronomical Journal, 2023
We present a transit-timing variation (TTV) and planetary atmosphere analysis of the Neptune-mass planet HAT-P-26 b. We present a new set of 13 transit light curves from optical ground-based observations and combine them with light curves from the Wide ...

Staging 18F-FDG PET/CT influences the treatment plan in melanoma patients with satellite or in-transit metastases

Melanoma research, 2020
Whole-body positron emission tomography/computed tomography (PET/CT) and brain magnetic resonance imaging (MRI) are commonly used to stage patients with palpable lymph node metastases from melanoma, but their role in patients with satellite and/or in ...

Optimization of a hierarchical hub and satellite network for urban freight on transit [PDF]

npj Sustainable Mobility and Transport
Growing urban populations drive the demand for urban goods movement, prompting interest in innovative urban logistics solutions. This study explores integrating passenger and freight transport by using public transport—the urban rail network—for parcel ...

Measuring positive public transit accessibility using big transit data

Geo-spatial Information Science, 2021
Most of the current existing accessibility measures quantify the potential of reaching desirable opportunities across space and time. Nevertheless, these potential measurements only illustrate the maximum possible accessibility a person can have, which ...

The chemokine receptor CXCR4 regulates satellite cell activation, early expansion, and self-renewal, in response to skeletal muscle injury

Frontiers in Cell and Developmental Biology, 2022
Acute skeletal muscle injury is followed by satellite cell activation, proliferation, and differentiation to replace damaged fibers with newly regenerated muscle fibers, processes that involve satellite cell interactions with various niche signals.

Comparison of Results From Transit Satellite Tracking [PDF]

Annals of Glaciology, 1988
Large-scale motions and strain-rates over great distances on polar ice sheets are often obtained from the tracking of Transit (or doppler) satellites. The results of different processing techniques for these tracking data are compared, using some of the data collected on and near Ice Stream C.

Navigation Using the Transit of an Artificial Satellite [PDF]

Journal of Navigation, 1960
F. G. Smith describes (this Journal, 13, 109) a system for determining position from a single observation, probably lasting for a time of the order of a few minutes, of radio transmissions from an artificial Earth satellite. There are in this system two engineering difficulties which I think Dr.
