Teixeira singularities in 3D switched feedback control systems
This paper is concerned with the analysis of a singularity that can occur in three-dimensional discontinuous feedback control systems. The singularity is the two-fold — a tangency of orbits to both sides of a switching manifold....

Discovering Serendipity
Dengue is the most rapidly spreading mosquito-borne viral disease in the world, with an annual incidence of over 100 million infections (Malavige, 2006).
The disease is caused by four distinct, but closely related, virus...

The Teukolsky–Starobinsky constants
Abstract: The Teukolsky master equation describes the dynamics of massless fields with spin on a Kerr black hole. Under separation of variables, spin-reversal for this equation is accomplished through the so-called...
Translational control during developmental transitions
The many steps of gene expression, from the transcription of a gene to the production of its protein product, are well understood. Yet, transcriptional regulation has been the focal point for the study of gene expression during...

Direct Type I IFN but Not MDA5/TLR3 Activation of Dendritic Cells Is Required for Maturation and Metabolic Shift to Glycolysis after Poly IC Stimulation
Type I interferons (IFNs) play an important role in direct antiviral defense as well as linking the innate and adaptive immune responses. On dendritic cells (DCs), IFNs facilitate their activation and contribute to CD8+ and CD4+...

L(3)mbt and the LINT complex safeguard cellular identity in the Drosophila ovary.
Maintenance of cellular identity is essential for tissue development and homeostasis. At the molecular level, cell identity is determined by the coordinated activation and repression of defined sets of genes. The tumor...
Mode Stability for the Teukolsky Equation on Extremal and Subextremal Kerr Spacetimes

Abstract: We prove that there are no exponentially growing modes nor modes on the real axis for the Teukolsky equation on Kerr black hole spacetimes, both in the extremal and subextremal case. We also give a quantitative...

Emergence of biaxial nematic phases in solutions of semiflexible dimers.
We investigate the isotropic, uniaxial nematic and biaxial nematic phases, and the transitions between them, for a model lyotropic mixture of flexible molecules consisting of two rigid rods connected by a spacer with variable...
Hidden Spectral Symmetries and Mode Stability of Subextremal Kerr(-de Sitter) Black Holes
Abstract: We uncover hidden spectral symmetries of the Teukolsky equation in Kerr(-de Sitter) black holes, recently conjectured by Aminov, Grassi and Hatsuda (Ann. Henri Poincaré 23, 1951-1977, 2022, and Gen. Relativ. Grav....

Xist RNA has been established as the master regulator of X-chromosome inactivation (XCI) in female eutherian mammals, but its mechanism of action remains unclear. By creating novel Xist-inducible mutants at the endogenous locus...
Efficacy and safety of rituximab in the treatment of eosinophilic granulomatosis with polyangiitis.
