Structure-Aware Matrix Pencil Method

We address the problem of detecting the number of complex exponentials and estimating their parameters from a noisy signal using the Matrix Pencil (MP) method. We introduce the MP modes and present their informative spectral structure. We show theoretically that these modes can be divided into signal and noise modes, where the signal modes exhibit a ...

Non- Sensitive Matrix Pencil method against mutual coupling

IEICE Electronics Express, 2011
A new Matrix Pencil (MP) method including mutual coupling effects based on a Uniform Linear Array (ULA) is presented. By setting a group of elements as auxiliary on each side of the ULA, it can accurately estimate the Direction of Arrival (DOA) using a single snapshot of data and the effect of mutual coupling can be eliminated by the inherent mechanism

Nomogram integrating MRI radiomics and white matter hyperintensity grading for predicting overall survival in patients with non‐small cell lung cancer and brain metastases receiving whole‐brain radiotherapy

Precision Radiation Oncology, EarlyView.
A prognostic nomogram integrating radiomic features and white matter hyperintensity (WMH) grading was developed to enable individualized survival prediction in patients with brain metastases (BMs). Integration of these imaging biomarkers into the clinical model enhanced predictive performance, indicating their incremental prognostic value for BM ...

From Purpose to Proof: Sustainability Framings and Substantiation Signals in Award‐Winning Advertising (2020–2025)

Sustainable Development, EarlyView.
ABSTRACT Drawing on signaling theory, this exploratory content analysis examines how elite advertising awards operate as institutional gatekeepers for sustainability communication. A comparative corpus of award‐winning campaigns (2020–2025; N = 83) is used to trace observable substantiation signals rather than to verify sustainability performance or ...

A New Jammer Suppression Method in MIMO Radar Using Matrix Pencil Method and Generalized Likelihood Ratio Test

International Journal of Antennas and Propagation, 2015
We propose a new algorithm to suppress the jammer signals and estimate the direction of arrival (DOA) of the signal of interest (SOI) for collocated MIMO radar by using the matrix pencil method (MPM) and the generalized likelihood ratio test (GLRT).

Speaking with the hands—fine motor skills, language, and the role of gestures

British Journal of Developmental Psychology, EarlyView.
Abstract Previous investigations link fine motor skills (FMS) with language development. Studies also examined relations between motor actions and gestures, as well as between gestures and language. However, little research has systematically investigated fine motor skills, manual gestures, and language within the same study or investigated their ...

Decoupled Estimation of 2D DOA for Coherently Distributed Sources Using 3D Matrix Pencil Method

EURASIP Journal on Advances in Signal Processing, 2008
A new 2D DOA estimation method for coherently distributed (CD) source is proposed. CD sources model is constructed by using Taylor approximation to the generalized steering vector (GSV), whereas the angular and angular spread are separated from signal ...

Exploring the trajectories of boredom: Revisiting overchallenged and underchallenged profiles in primary school mathematics

British Journal of Educational Psychology, EarlyView.
Abstract Background Numerous studies have demonstrated the importance of academic emotions for learning, with boredom attracting significant attention due to its frequent occurrence in school life and the increasing evidence of its negative effects on academic results and motivation. Aims Building on Schwartze et al. (2024), this study examined whether

Primary school students' achievement emotions in writing acquisition: Development of the AEQ‐WEES and links to students' writing competencies and social integration over time

British Journal of Educational Psychology, EarlyView.
Abstract Background Acquiring writing skills poses not only cognitive but also emotional challenges for many primary school students. Although achievement emotions have received increasing research attention in recent years, little is known about how these emotions unfold during the process of writing acquisition and how they relate to both academic ...

Style Brush: Guided Style Transfer for 3D Objects

Computer Graphics Forum, EarlyView.
We introduce Style Brush, a guided 3D style‐transfer method for textured meshes that provides precise creative control. It supports the use of multiple style images, smooth transitions and intuitive guidance, producing visually appealing textures that follow user intent as we demonstrate in our user study and results. Abstract We introduce Style Brush,
