Transcatheter Repair of Sinus Venosus Defect Using a 12‐zig Covered Cheatham‐Platinum Stent in Large Superior Vena Cava—Right Atrium Junctions: Early Multicenter Experience

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Sinus venosus defect (SVD) is a rare congenital heart anomaly characterised by an abnormal communication between the atria, often associated with partial anomalous pulmonary venous connection (PAPVC). Traditional surgical repair carries significant risks, prompting exploration into less invasive transcatheter approaches.

Quenching the Hubbard Model: Comparison of Nonequilibrium Green's Function Methods

Contributions to Plasma Physics, EarlyView.
ABSTRACT We benchmark nonequilibrium Green's function (NEGF) approaches for interaction quenches in the half‐filled Fermi–Hubbard model in one and two dimensions. We compare fully self‐consistent two‐time Kadanoff–Baym equations (KBE), the generalized Kadanoff–Baym ansatz (GKBA), and the recently developed NEGF‐based quantum fluctuations approach (NEGF‐

The Relation Between the EVD or SVD of Summands and the EVD or SVD of the Sum

CoRR
In this work, we show how the eigenstructures of summands are related to that of the sum. In particular, we show that the sum of two positive semidefinite matrices can be written as the inner product of two block matrices $\mathbf{C} = \mathbf{A} + \mathbf{B} = \mathbf{PD}^2\mathbf{P}^T + \mathbf{QE}^2\mathbf{Q}^T = \begin{pmatrix} \mathbf{PD} & ...

Gaborlet‐guided sparse filtering: A novel intelligent method for lithology identification by vibration signals while drilling

Deep Underground Science and Engineering, EarlyView.
The flowchart illustrates rock specimen testing, vibration signal acquisition, and feature extraction with Gaborlet and sparse filtering for classification. Abstract Traditional lithology identification methods mainly rely on core sampling and well‐logging data.

Subspace Acceleration for Efficient Nonlinear Water Wave Simulation

International Journal for Numerical Methods in Fluids, EarlyView.
We introduce an exponentially weighted subspace acceleration technique to reduce GMRES iterations for solving the Poisson equation with time‐dependent coefficients in nonlinear, dispersive free‐surface flows governed by the incompressible Navier‐Stokes equations. The method significantly reduces memory requirements and computational complexity compared

Human action recognition based on back propagation neural network

网络与信息安全学报, 2017
For human action recognition,an algorithm for classifying human action based on back propagation (BP) neural network was proposed.Firstly,singular value decomposition (SVD) was used to extract the singular value of each frame of the video.Then each row ...

A multilevel perspective on MSH6‐associated Lynch syndrome: Integrating molecular, biological, and clinical insights

International Journal of Cancer, EarlyView.
Abstract Lynch syndrome (LS) is the most common hereditary colorectal cancer syndrome, caused by a germline pathogenic variant in one of the mismatch repair (MMR) genes. Among these, MSH6‐associated LS represents a distinct subtype with unique molecular and clinical characteristics.

Functional status of women with and without potentially life‐threatening maternal conditions after 6 months postpartum: A cohort study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective The aim of this study was to evaluate the impact of potentially life‐threatening maternal conditions (PLTCs) on functional disability at 6 months postpartum. Methods This prospective cohort study was done at 10 hospitals in Tigray, northern Ethiopia. A total of 1027 postpartum women (341 with PLTCs and 686 without) were enrolled into

Dobi-SVD: Differentiable SVD for LLM Compression and Some New Perspectives

CoRR
We provide a new LLM-compression solution via SVD, unlocking new possibilities for LLM compression beyond quantization and pruning. We point out that the optimal use of SVD lies in truncating activations, rather than merely using activations as an optimization distance.
