Geometric Constrained Non-Line-of-Sight Imaging

open access: yes
Normal reconstruction is crucial in non-line-of-sight (NLOS) imaging, as it provides key geometric and lighting information about hidden objects, which significantly improves reconstruction accuracy and scene understanding. However, jointly estimating normals and albedo expands the problem from matrix-valued functions to tensor-valued functions that ...

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

open access: yesAnatomical 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

open access: yesAstronomische 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

open access: yesBatteries &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

open access: yesBritish 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.

Understanding Noise and Interference Regimes in 5G Millimeter-Wave Cellular Networks

open access: yes, 2016
With the severe spectrum shortage in conventional cellular bands, millimeter-wave (mmWave) frequencies have been attracting growing attention for next-generation micro- and picocellular wireless networks. A fundamental and open question is whether mmWave
