Improving independent vector analysis in speech and noise separation tasks [PDF]

, 2015
Independent vector analysis (IVA) is an efficient multichannel blind source separation method. However, source models conventionally assumed in IVA present some limitations in case of speech and noise separation tasks.

Stacking Fault Complexions in AgSbTe2 Thermoelectrics With Enhanced Electrical Conductivity

Advanced Functional Materials, Volume 36, Issue 65, 13 August 2026.
Atomic‐scale characterization resolves stacking fault complexion in AgSbTe2, showing Te and Sb segregation along with lattice dilation. Their enhanced effects on phonon scattering are modeled analytically. Although most defects also impede electron transport, local four‐point‐probe measurements reveal higher electrical conductivity at stacking fault ...

Longitudinal Molecular Epidemiology and Genomic Surveillance of Carbapenem‐Resistant Klebsiella pneumoniae in the Gut of Healthy Individuals in China

MedComm, Volume 7, Issue 8, August 2026.
Using 16,040 stool samples from healthy individuals across 30 Chinese provinces (2016–2024), we performed longitudinal genomic surveillance of carbapenem‑resistant Klebsiella pneumoniae (CRKP) colonizing the gut. We reveal rising community CRKP prevalence, especially in southern China, a shift from blaKPC‐2 to plasmid‑borne blaNDM‐5 on IncHI2/IncHI2A ...

Independent Vector Analysis: Theory, Algorithms, and Applications [PDF]

, 2013
The field of blind source separation (BSS) is a well studied discipline within the signal processing community due to its applicability to a variety of problems when the data observation model is poorly known or difficult to model.

Auxiliary function based IVA using a source prior exploiting fourth order relationships [PDF]

, 2013
International audienceIndependent vector analysis (IVA) can theoretically avoid the permutation ambiguity present in frequency domain independent component analysis by using a multivariate source prior to retain the dependency between different frequency

Effect of Flow Dynamics on Two‐Phase Flow Patterns in Porous Media

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract This study investigates the impact of flow dynamics on liquid‐gas two‐phase flow patterns within a two‐dimensional millifluidic porous medium. Based on high‐fidelity analysis of experimental images and simplified single‐phase flow pore network models (PNM), we examine co‐injection two‐phase flow configurations across varying injection rates ...

Epithelial YPEL3 Modulates CD8+ T‐Cell Infiltration and Tumor Progression Through CREB1–CXCL16 Signaling in HNSCC

Cancer Science, Volume 117, Issue 8, Page 2132-2151, August 2026.
YPEL3 functions as a tumor suppressor in HNSCC by inhibiting tumor progression and promoting apoptosis. Mechanistically, it enhances epithelial–immune crosstalk through the CREB1‐mediated CXCL16–CXCR6 axis, facilitating CD8+ T‐cell infiltration and highlighting its potential as a prognostic biomarker and immunotherapy target.

CNGCs in Marchantia paleacea uncouple arbuscular mycorrhizal symbiosis and rhizoid development

New Phytologist, Volume 251, Issue 4, Page 2027-2040, August 2026.
Rhizoid growth and AM fungal infection are uncoupled. Summary In Marchantia paleacea, MpaDMI1‐dependent nuclear Ca2+ oscillations are essential for arbuscular mycorrhizal (AM) fungal colonisation, indicating that endosymbiosis‐mediated nuclear Ca2+ signalling is a conserved feature of land plant–AM symbiosis.
