Generalized spatial modulation in indoor wireless visible light communication

, 2014
In this paper, we investigate the performance of generalized spatial modulation (GSM) in indoor wireless visible light communication (VLC) systems. GSM uses Nt light emitting diodes (LED), but activates only Na of them at a given time. Spatial modulation

How Much Physics Should a Neural Network Know? Thermodynamics‐Informed Neural Networks for Rock Constitutive Modeling With Epistemic Uncertainty

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Machine learning offers a flexible route to constitutive modeling, with two emergent questions for geoscience applications: what level of thermodynamic constraint should be embedded in the network architecture, and how should predictive uncertainty be quantified when extrapolating from laboratory to field conditions? We address both challenges

Spatial modulation aided zero-padded single carrier transmission for dispersive channels [PDF]

, 2013
In this paper, we consider spatial modulation (SM) operating in a frequency-selective single-carrier (SC) communication scenario and propose zero-padding instead of the cyclic-prefix considered in the existing literature.

Joint Design of the Spatial and of the Classic Symbol Alphabet Improves Single-RF Spatial Modulation

IEEE Access, 2016
A new joint spatial and classic symbol alphabet is designed for spatial modulation (SM)-based multiple-input multiple-output systems. The employment of multiple active antennas instead of a single active antenna is proposed for increasing the achievable ...

The dynamic functional connectivity peak index: Detection of interictal epileptic activity with fMRI

Epilepsia, Volume 67, Issue 9, Page 4702-4716, September 2026.
Abstract Objective Epileptogenic zone (EZ) localization is crucial for surgical treatment of patients with medication‐resistant epilepsy. Although simultaneous electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) can detect interictal discharges for EZ localization, clinical adoption is limited by the need for specialized ...

Generalized Spatial Modulation in Indoor Wireless Visible Light Communication [PDF]

, 2016
In this paper, we investigate the performance of generalized spatial modulation (GSM) in indoor wireless visible light communication (VLC) systems. GSM uses N-t light emitting diodes (LED), but activates only N-a of them at a given time.

Impacts of Neutral Wind‐Driven Currents on Geomagnetic Disturbances and Magnetospheric Dynamics During the May 2024 Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The neutral wind dynamo generates ionospheric currents that can significantly affect high‐latitude electrodynamics during geomagnetic storms, yet its role in global magnetosphere‐ionosphere coupling is often underrepresented. We quantify the impact of wind‐driven currents on geomagnetic disturbances (GMDs) and magnetospheric dynamics during ...
