Dancing to multiple tunes: Establishing legitimacy with first‐time and repeat backers in crowdfunding campaigns

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Using 14,108 Kickstarter crowdfunding campaigns, we examine three strategies to gather support from first‐time versus repeat backers: narrative distinctiveness aligning with backers' expectations of novelty, endorsement from Kickstarter staff, and campaign leadership's reciprocity of funding other campaigns.

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 ...

TMSA‐Net: Transformer‐Based Multi‐Scale Attention U‐Net for Flood Image Segmentation

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Flood detection is essential for real‐time applications, including disaster management, emergency response, and alerting people in flood zones. For successful flood detection, accurate flood region segmentation is essential. However, the flood region segmentation is challenging due to the complex background and occlusions with debris and the ...

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.

Range-ambiguous Clutter Suppression for Forward-looking Frequency Diverse Array Space-time Adaptive Processing Radar

open access: yesLeida xuebao, 2015
In a high pulse-repetitive-frequency forward-looking radar, the clutter echo is not only severely rangedependent but also range-ambiguous. It is therefore difficult to realize clutter compensation and suppression for conventional Space-Time Adaptive ...
