Spectral characterization of hierarchical network modularity and limits of modularity detection.

PLoS ONE, 2013
Many real world networks are reported to have hierarchically modular organization. However, there exists no algorithm-independent metric to characterize hierarchical modularity in a complex system.

Targeting the YAP‐BST2 Axis Overcomes Intrinsic Anti‐PD‐1 Resistance in Metastatic Gastric Cancer

Advanced Science, EarlyView.
Concurrent YAP hyperactivation and Tp53 loss in Atp4b‐expressed parietal cell lineage drives gastric cancer initiation, multi‐organ metastasis, and intrinsic resistance to anti‐PD‐1 therapy. BST2 emerges as a direct YAP‐TEAD transcriptional target that engages PIRA2 on myeloid cells to establish an immunosuppressive microenvironment.

Bounds on complex eigenvalues and resonances

, 2001
We obtain bounds on the complex eigenvalues of non-self-adjoint Schrodinger operators with complex potentials, and also on the complex resonances of self-adjoint Schrodinger operators.

Green's Functions of Non‐Hermitian Systems at Exceptional Deficiency

Advanced Science, EarlyView.
We analyze the responses of a non‐Hermitian lattice system under the condition of exceptional deficiency (ED), when all bands in the system are formed by exceptional points. Using the frequency domain, we identify novel steady‐state responses that root in the broadband super‐Lorentzian Green's function (GF).

Brain Network Dynamics of Local and Global Predictive Processing in Aging

Advanced Science, EarlyView.
Separation of concurrent whole‐brain networks in source‐reconstructed magnetoencephalography (MEG) data suggests that healthy aging reorganizes, rather than uniformly attenuates, neural responses elicited from hierarchical auditory violations. Enhanced early sensory deviance processing alongside reduced higher‐order cognitive responses suggests a large‐

A Survey on the Eigenvalues Local Behavior of Large Complex Correlated Wishart Matrices

ESAIM: Proceedings and Surveys, 2015
The aim of this note is to provide a pedagogical survey of the recent works [30, 31] concerning the local behavior of the eigenvalues of large complex correlated Wishart matrices at the edges and cusp points of the spectrum: Under quite ...

Thermal Shifts Dominate Single‐Gene Responses to Transcription‐Targeting Antibiotics

Advanced Science, EarlyView.
Thermal shifts reshape bacterial responses to transcription‐targeting antibiotics. In E. coli, temperature can dominate antibiotic‐induced genome‐wide expression, particularly outside 30°C–39°C, through changes in adenosine triphosphate (ATP), nucleoid organization, and drug‐target engagement.

Analytical Prediction of Critical Transitions in Oscillator Networks With Non‐Local Links

Advanced Science, EarlyView.
An analytical framework reveals how global coupling, second‐harmonic strength, noise, and network structure govern oscillator‐based Ising dynamics. Spectral reduction predicts stability boundaries, while Fokker–Planck analysis captures one‐ to two‐cluster transitions and identifies conditions favoring low‐energy configurations.
