The Quasi-Kronecker Form For Matrix Pencils [PDF]

SIAM Journal on Matrix Analysis and Applications, 2012
We study singular matrix pencils and show that the so-called Wong sequences yield a quasi-Kronecker form. This form decouples the matrix pencil into an underdetermined part, a regular part, and an overdetermined part. This decoupling is sufficient to fully characterize the solution behavior of the differential-algebraic equations associated with the ...

Twenty‐four month clinical outcomes of modified coronally advanced tunnel technique with leukocyte‐ and platelet‐rich fibrin–functionalized porcine dermal matrix for single/multiple gingival recessions

Journal of Periodontology, EarlyView.
Abstract Background To report 24‐month clinical and 3D outcomes of single and multiple RT1 and RT2 gingival recessions treated with the modified coronally advanced tunnel (MCAT) technique and an L‐PRF‐functionalized porcine dermal matrix (PDM), as long‐term data on PDM in root coverage are scarce.

Nutritional and sensory characteristics of local and hybrid East African Highland cooking bananas: Implications for breeding programs

JSFA reports, EarlyView.
Abstract Background Bananas (Musa species) are an important staple food and cash crop in many parts of the world. The East African Highland cooking bananas form the backbone of food security for millions of Ugandans. The demand for high quality cooking bananas is thus closely linked to their sensory characteristics (which drive consumer preference) and

Sylvester matrix equation for matrix pencils

Linear Algebra and its Applications, 1996
Let be given complex matrices \(B_1\), \(A_1 \in \mathbb{C}^{p_1 \times q_1}\) and \(B_2\), \(A_2 \in \mathbb{C}^{p_2 \times q_2}\), and consider the homogeneous system of equations \[ A_1 X - YA_2 = 0, \quad B_1 X - YB_2 = 0. \tag{1} \] The dimension of the set of solutions of (1) is obtained in terms of the Kronecker invariants of the matrix pencils \

Superior Labial Artery Flap for Septal Perforation Repair: The Boxer's Flap

The Laryngoscope, EarlyView.
The nasal floor flap, or Boxer's flap, is an anteriorly pedicled, superior labial artery–based mucosal flap that provides excellent closure rates in septal perforation repair when traditional septal flaps are not feasible. The schematic shows: (A) preoperative perforation, (B) nasal floor flap elevation (with the pedicle maintained at the inferior ...

Adapted Linear Binning Method to Assess Pulmonary Ventilation and Perfusion in Children Using Lung Matrix Pencil Decomposition (MP)‐MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To adapt and validate a linear binning technique, developed for hyper‐polarized 129Xe MRI, for functional lung MRI with matrix‐pencil decomposition (MP)‐MRI. Methods First, a dedicated normalization was applied to the perfusion‐weighted and the ventilation‐weighted map histograms.

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 ...
