Measurement-Based LoS/NLoS Channel Modeling for Hot-Spot Urban Scenarios in UMTS Networks

International Journal of Antennas and Propagation, 2014
A measurement campaign is introduced for modeling radio channels with either line-of-sight (LoS) or non-line-of-sight (NLoS) connection between user equipment (UE) and NodeB (NB) in an operating universal mobile telecommunications system.

Hiding in Plain Sight: Rethinking the Size and Complexity of Iron Age Hillforts in NW Iberia Thanks to Aerial Archaeology and Geophysics

Archaeological Prospection, EarlyView.
ABSTRACT This paper tackles one key limitation in the analysis of Iron Age communities in the Northwestern Iberian Peninsula: the limited exploration of areas beyond the fortified settlements known as castros (hillforts). The vast majority of archaeological studies have focused exclusively on the areas inside the walls of these settlements, which are ...

Digital Spatial Technologies to Compose the Map of the Southeast Iberia Megalithic Phenomenon. The Case Study of Fonelas (Granada, Spain)

Archaeological Prospection, EarlyView.
ABSTRACT Megalithic landscapes in Southeast Iberia remain unevenly and insufficiently documented, particularly in rugged areas where traditional survey methods are limited. This paper addresses this gap by applying a multiscalar approach to the megalithic necropolises of the Fardes River (Granada, Spain), with the objective of detecting, documenting ...

Cutting Through the Green: A Case for Grassland Archaeology Using UAV Multispectral Data

Archaeological Prospection, EarlyView.
ABSTRACT Advances in low‐altitude remote sensing are needed to improve the effectiveness of archaeological prospection in the Netherlands. The geomorphological situation and land use history make applying various remote sensing and geophysical technologies particularly challenging.

“A lot of it is about feel”: The promise of sensory ethnography for anatomical education research

Anatomical Sciences Education, EarlyView.
Abstract Ethnographers have constructed rich accounts of cultural settings since the early nineteenth century. A new approach, sensory ethnography, holds great promise for Health Professions Education scholars in its incorporation of the senses, particularly regarding anatomical teaching and learning. In this article, we describe sensory ethnography as

Discovery and Initial Investigation of a New Low Surface Brightness Planetary Nebula Candidate at High Galactic Latitude

Astronomische Nachrichten, EarlyView.
ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...

Synergetic Combination of Carbon Xerogels, Graphene Oxide and nano‐ZnO for Aqueous and Organic Supercapacitors

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
This work proposes the synthesis of carbon‐based nanostructured materials obtained using ZnO as both nanos‐ template and catalysts simultaneously. During the synthesis, GO was used as a stabiliser, preventing the collapse of the 3D structure and improving its properties in terms of capacitance and surface area.

‘The best year’/‘I struggled with everything’: Widening participation experiences of pandemic online learning

British Educational Research Journal, EarlyView.
Abstract Improving retention and graduate outcomes for students from a widening participation (WP) background is key to achieving more equitable outcomes. However, evidence suggests WP students experienced different challenges than their peers during the COVID‐19 pandemic.

Adaptive Beam Pairing and Local Interpolation for Robust Analytical Beam Training in RIS-Assisted Wideband THz Systems

IEEE Open Journal of the Communications Society
Wideband terahertz (THz) communication systems offer ultra-high data rates and low latency for future sixth-generation (6G) networks, but they face severe path loss and beam split effects that degrade direction estimation in reconfigurable intelligent ...
