Loanwords and Linguistic Phylogenetics: *pelek̑u‐ ‘axe’ and *(H)a(i̯)g̑‐ ‘goat’1

open access: yesTransactions of the Philological Society, Volume 123, Issue 1, Page 116-136, March 2025.
Abstract This paper assesses the role of borrowings in two different approaches to linguistic phylogenetics: Traditional qualitative analyses of lexemes, and quantitative computational analysis of cognacy. It problematises the assumption that loanwords can be excluded altogether from datasets of lexical cognacy.

Subspace Compressive GLRT Detector for MIMO Radar in the Presence of Clutter

open access: yesThe Scientific World Journal, 2015
The problem of optimising the target detection performance of MIMO radar in the presence of clutter is considered. The increased false alarm rate which is a consequence of the presence of clutter returns is known to seriously degrade the target detection

Polarisation-space-time adaptive processing for heterogeneous clutter suppression of airborne-phased array radar

open access: yesThe Journal of Engineering, 2019
Conventional space-time adaptive processing (STAP) achieves clutter suppression by combining spatial signals and the temporal pulses. However, extreme slow-moving target cannot be effectively detected by space-time joint filtering in ambiguous and non ...

Navigating Contested Spaces: Gendered Interactions in Everyday Entrepreneuring Among Jua Kali Women in Rural Kenya

open access: yesGender, Work &Organization, EarlyView.
ABSTRACT This paper examines the daily experiences of Jua Kali women entrepreneurs in Western Kenya, unpacking how gendered power relations are enacted within informal marketplaces and how women entrepreneurs mobilize agency within these structurally and institutionally constrained contexts.

Doppler polarimetric ground clutter identification and suppression for atmospheric radars based on co-polar correlation

open access: yesJournal of Telecommunications and Information Technology, 2001
A new clutter suppression technique that uses both Doppler and polarimetric information is presented. Polarimetric properties of the target and clutter are calculated per Doppler frequency cell and based on this information clutter suppression is ...

Deep Reinforcement Learning Based Autonomous Decision‐Making for Cooperative Uncrewed Aerial Vehicles: A Search and Rescue Real World Application

open access: yesJournal of Field Robotics, Volume 43, Issue 7, Page 4382-4401, October 2026.
ABSTRACT This paper presents the first end‐to‐end framework that combines guidance, navigation, and centralized task allocation for multiple UAVs performing autonomous search‐and‐rescue (SAR) in GNSS‐denied indoor environments. A twin delayed deep deterministic policy gradient controller is trained with an artificial potential field (APF) reward that ...

Automated Lawn Maintenance: An Agronomic and Operational Review of Turf Health, Biodiversity, and Field Performance

open access: yesJournal of Field Robotics, Volume 43, Issue 7, Page 4603-4623, October 2026.
ABSTRACT Grass mowing is one of the most resource‐consuming activities in green maintenance, whether in private areas such as home gardens or in public spaces like urban parks. In recent years, concerns related to climate change, human health, and sustainability have become increasingly prominent in green maintenance, leading manufacturers and industry
