The Distributed MIMO Scenario: Can Ideal ADCs Be Replaced by Low-resolution ADCs? [PDF]

, 2017
This letter considers the architecture of distributed antenna system, which is made up of a massive number of single-antenna remote radio heads (RRHs), some with full-resolution but others with low-resolution analog-to-digital converter (ADC) receivers ...

Waves of range dynamics and gene flow characterize the biogeographic history of Litsea elongata, a dominant tree in East Asian evergreen broadleaved forests

PLANTS, PEOPLE, PLANET, EarlyView.
Evergreen broadleaved forests (EBLFs) represent an iconic vegetation type in subtropical montane East Asia, but they are experiencing intensifying anthropogenic pressure and increasing habitat fragmentation. Here, using a dominant and widespread tree species characteristic of East Asian EBLFs, we examine its phylogeographic history and evaluate what it

Power Minimizing BBU-RRH Group Based Mapping in C-RAN with Constrained Devices [PDF]

ICC 2020 - 2020 IEEE International Conference on Communications (ICC), 2020
C-RAN presents an advanced mobile networking architecture that promises to tackle various challenging aspects of 5G such as increasing energy efficiency and providing high capacity. Indeed, C-RAN paves the way toward better energy efficiency by centralizing the baseband processing at cloud computing based servers (BBU pool).

Echo State Networks for Proactive Caching in Cloud-Based Radio Access Networks with Mobile Users

, 2017
In this paper, the problem of proactive caching is studied for cloud radio access networks (CRANs). In the studied model, the baseband units (BBUs) can predict the content request distribution and mobility pattern of each user, determine which content to

Targeted herbicide spraying systems: role of nozzle type, number of nozzle activation, nozzle orientation, and boom height on spray coverage and weed control

Pest Management Science, EarlyView.
Targeted herbicide application technology performance depends on sprayer configuration. Across five studies, activation of multiple, overlapping nozzles and maintaining appropriate boom height consistently improved spray coverage and weed control, highlighting the importance of optimized sprayer setup for effective and reliable weed control.

National Relics: Secular Sacrality, Museums, and Heritage‐Making in Nineteenth‐Century Chile

Museum Anthropology, Volume 49, Issue 2, Fall 2026.
ABSTRACT This article examines how objects and bodily remains are transformed and ritualized into national relics through collecting and exhibiting practices in museums. Focusing on nineteenth‐century Chile, it draws on archival sources, material culture theory, and the anthropology of religion to argue that objects associated with Chile's nation‐state

Multiservice Loss Models in Single or Multi-Cluster C-RAN Supporting Quasi-Random Traffic

Applied Sciences, 2021
In this paper, a cloud radio access network (C-RAN) is considered where the baseband units form a pool of computational resource units and are separated from the remote radio heads (RRHs).

Local free-fall temperature of a RN-AdS black hole

, 2009
We use the global embedding Minkowski space (GEMS) geometries of a (3+1)-dimensional curved Reissner-Nordstr\"om(RN)-AdS black hole spacetime into a (5+2)-dimensional flat spacetime to define a proper local temperature, which remains finite at the event ...

Integrating image‐based phenotyping and marker‐assisted selection to optimize the selection of potato clones for chipping and resistance to viruses X and Y

Crop Science, Volume 66, Issue 3, May/June 2026.
Abstract Potato (Solanum tuberosum L.) is the most important non‐cereal crop for global food security. To meet the demands of the processing, potato clones with good frying quality and industrial yield and resistance to major viral diseases are required. This study aimed to integrate image‐based phenotyping and marker‐assisted selection to optimize the
