Patterns of grey and white matter changes differ between bulbar and limb onset amyotrophic lateral sclerosis

open access: yesNeuroImage: Clinical, 2021
Amyotrophic Lateral Sclerosis (ALS) is a progressive neurodegenerative disease that is characterized by a high heterogeneity in patients’ disease course. Patients with bulbar onset of symptoms (b-ALS) have a poorer prognosis than patients with limb onset

Totally umbilic surfaces in homogeneous 3-manifolds [PDF]

open access: yes, 2008
We discuss existence and classification of totally umbilic surfaces in the model geometries of Thurston and the Berger spheres. We classify such surfaces in $H^2 \times R$, $S^2 \times R$ and the Sol group. We prove nonexistence in the Berger spheres and

Adaptive Mesh Refinement for Characteristic Grids

open access: yes, 2010
I consider techniques for Berger-Oliger adaptive mesh refinement (AMR) when numerically solving partial differential equations with wave-like solutions, using characteristic (double-null) grids.

Ricci flow of warped Berger metrics on $\mathbb{R}^{4}$

open access: yes, 2021
We study the Ricci flow on $\mathbb{R}^{4}$ starting at an SU(2)-cohomogeneity 1 metric $g_{0}$ whose restriction to any hypersphere is a Berger metric.

Micropatterned Biphasic Printed Electrodes for High‐Fidelity on‐Skin Bioelectronics

open access: yesAdvanced Functional Materials, EarlyView.
Micropatterned biphasic printed electrodes achieve unprecedented skin conformity and low impedance by combining liquid‐metal droplets with microstructured 3D lattices. This scalable approach enables high‐fidelity detection of ECG, EMG, and EEG signals, including alpha rhythms from the forehead, with long‐term comfort and stability.

Dynamics of agricultural land and the risk to food insecurity in the Niayes region of Diamniadio, West Senegal

open access: yesJàmbá, 2017
Food security is a serious challenge facing West African countries because most croplands are being degraded. Consequently, agricultural production is being exceeded by rapid population growth. This study relates the dynamics of agricultural lands to the

Polar Actions on Berger Spheres [PDF]

open access: yes, 2006
The object of this article is to study a torus action on a so-called Berger sphere. We also make some comments on polar actions on naturally reductive homogeneous spaces. Finally, we prove a rigidity-type theorem for Riemannian manifolds carrying a polar
