Integer-modulated filter banks providing perfect reconstruction

, 2000
In this paper, we extend the perfect reconstruction conditions known for cosine modulation to other, more general modulation schemes. The modified PR conditions provide additional degrees of freedom which can be utilized to design integer-modulated ...

Toward the Application of Multiaxial Failure Criteria: Mean Stress Sensitivity of Carbide‐Rich, High‐Alloy PM‐HIP Tool Steels Under Axial and Torsional Cyclic Loading

steel research international, EarlyView.
This study quantifies axial and torsional long‐life fatigue (LLF) behavior of three carbide‐rich PM‐HIP tool steels, correlating LLF strength with intrinsic defect size and cleanliness, thereby extracting material‐specific mean stress sensitivities and Haigh diagrams.

AES‐Debye: an accurate, efficient and scalable engine for Debye scattering calculations

Journal of Applied Crystallography, EarlyView.
AES‐Debye is an accurate, efficient and scalable engine for evaluating the Debye scattering equation that enables total scattering calculations for large atomistic models. Corrected pair‐distance binning and numerically robust accumulation suppress discretization artifacts, while parallel CPU/GPU execution enables efficient computation of scattering ...

Variable‐Rate Texture Compression: Real‐Time Rendering with JPEG

Computer Graphics Forum, EarlyView.
Abstract Although variable‐rate compressed image formats such as JPEG are widely used to efficiently encode images, they have not found their way into real‐time rendering due to special requirements such as random access to individual texels. In this paper, we investigate the feasibility of variable‐rate texture compression on modern GPUs using the ...

On some new arithmetic functions involving prime divisors and perfect powers. [PDF]

, 2018
Integer division and perfect powers play a central role in numerous mathematical results, especially in number theory. Classical examples involve perfect squares like in Pythagora’s theorem, or higher perfect powers as the conjectures of Fermat (solved ...

Non‐Rigid 3D Shape Correspondences: From Foundations to Open Challenges and Opportunities

Computer Graphics Forum, EarlyView.
Abstract Estimating correspondences between deformed shape instances is a long‐standing problem in computer graphics; numerous applications, from texture transfer to statistical modelling, rely on recovering an accurate correspondence map. Many methods have thus been proposed to tackle this challenging problem from varying perspectives, depending on ...

Reproducibility assessment of Dextrusion: A deep learning pipeline for detecting epithelial cell extrusion events

Journal of Microscopy, EarlyView.
Abstract Reproducibility is essential for scientific software but can be hindered by technical and maintenance challenges. As part of the Global Bioimage Analyst Society reproducibility initiative, we evaluated Dextrusion, a deep learning pipeline for detecting epithelial cell extrusion events published by Villars et al.

Multimodal Video Summarization Using Vision‐Language Embeddings and Hierarchical Temporal Modeling

Applied AI Letters, Volume 7, Issue 3, October 2026.
Combining BLIP‐2 image captions with CLIP vision–language embeddings gives video frames semantic meaning that pixels alone cannot convey. Processed by a multi‐scale temporal U‐Net and hierarchical shot‐aware transformer, these multimodal features achieve a state‐of‐the‐art 59.27% F1‐score on SumMe using only 28.27M parameters.

Analysis of Eigenvalue Clustering Leads to Optimal Scaling in Numerical Radiative Transfer

Numerical Linear Algebra with Applications, Volume 33, Issue 5, October 2026.
ABSTRACT We consider a multidimensional polychromatic radiative transfer (RT) problem, accounting for scattering processes in a general form, that is, anisotropic (dipole) scattering with partial frequency redistribution. Given a discrete ordinates (SN$$ {S}_N $$) discretization, we report the corresponding matrix structures, depending on the model and

Generation of High Energy-Efficiency Perfect Gaussian Integer Sequences and OTFS Pilot Design

Tongxin xuebao
To enhance the channel estimation accuracy of orthogonal time frequency space (OTFS) systems in high-mobility scenarios, a novel pilot design scheme based on high-energy-efficiency perfect Gaussian integer sequences (PGIS) was proposed.
