Nerves Around the Shoulder: What the Radiologist Should Know?

Journal of the Belgian Society of Radiology, 2017
Peripheral neuropathies of the shoulder are common and could be related to traumatic injury, shoulder surgery, infection or tumour but usually they result from an entrapment syndrome.

PeakForce AFM Analysis Enhanced with Model Reduction Techniques

Sensors, 2023
PeakForce quantitative nanomechanical AFM mode (PF-QNM) is a popular AFM technique designed to measure multiple mechanical features (e.g., adhesion, apparent modulus, etc.) simultaneously at the exact same spatial coordinates with a robust scanning ...

The atypical cadherin flamingo determines the competence of neurons for activity-dependent fine-scale topography

Molecular Brain, 2019
The topographic projection of afferent terminals into two-dimensional maps is essential for sensory systems to encode the locations of sensory stimuli. In vertebrates, guidance cues are critical for establishing a coarse topographic map, while neuronal ...

Global Models From Sparse Data: A Robust Estimate of Earth's Residual Topography Spectrum

Geochemistry, Geophysics, Geosystems, 2020
A significant component of Earth's surface topography is maintained by stresses induced by underlying mantle flow. This “dynamic” topography cannot be directly observed, but it can be approximated—particularly at longer wavelengths—from measurements of ...

Rapid surface uplift and crustal flow in the Central Andes (southern Peru) controlled by lithospheric drip dynamics

Scientific Reports, 2022
The high flux magmatism, crustal shortening/extension and plateau formation in Cordilleran orogenic systems have been explained by removal of lithosphere (lower crust and the sub-arc mantle lithosphere) that develops beneath the magmatic arc and ...

An Improved Sparse Bayesian Learning SAR Tomography Method and its Application for Forest Vertical Structure Inversion

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Synthetic aperture radar tomography (TomoSAR) is widely used in reconstructing forest vertical structure, but accurately locating both ground and canopy scatterers in dense forest areas remains challenging.

Data-driven exploration of orographic enhancement of precipitation [PDF]

Advances in Science and Research, 2011
This study presents a methodology to analyse orographic enhancement of precipitation using sequences of radar images and a digital elevation model. Image processing techniques are applied to extract precipitation cells from radar imagery.

The arc-scale spatial distribution of volcano erosion implies coupled magmatism and regional climate in the Cascades arc, United States

Frontiers in Earth Science, 2023
The morphology and distribution of volcanic edifices in volcanic terrains encodes the structure and evolution of underlying magma transport as well as surface processes that shape landforms.

The influence of surface characteristics, topography and continentality on mountain permafrost in British Columbia [PDF]

The Cryosphere, 2015
Thermal and surface offsets describe mean annual ground temperature relative to mean annual air temperature, and for permafrost modelling they are often predicted as a function of surface characteristics and topography.

Cervical Spinal Cord Atrophy Profile in Adult SMN1-Linked SMA. [PDF]

PLoS ONE, 2016
PURPOSE:The mechanisms underlying the topography of motor deficits in spinal muscular atrophy (SMA) remain unknown. We investigated the profile of spinal cord atrophy (SCA) in SMN1-linked SMA, and its correlation with the topography of muscle weakness ...
