Isomonodromic deformation of resonant rational connections
, 2005 We analyze isomonodromic deformations of rational connections on the Riemann sphere with Fuchsian and irregular singularities. The Fuchsian singularities are allowed to be of arbitrary resonant index; the irregular singularities are also allowed to be ...

The role of U(1)’s in 5d theories, Higgs branches, and geometry
Journal of High Energy Physics, 2020 We explore the Higgs branches of five-dimensional N $$ \mathcal{N} $$ = 1 quiver gauge theories at finite coupling from the paradigm of M-theory on local Calabi-Yau threefolds described as ℂ∗-fibrations over local K3’s.

Simple tangential families and perestroikas of their envelopes [PDF]
, 2004 Tangential families are 1-parameter families of rays emanating tangentially from smooth curves. We classify tangential family germs up to Left-Right equivalence: we prove that there are two infinite series and four sporadic simple singularities of ...

Apparent singularities of Fuchsian equations, and the Painlev\'e VI equation and Garnier systems
, 2009 We study movable singularities of Garnier systems using the connection of the latter with isomonodromic deformations of Fuchsian systems. Questions on the existence of solutions for some inverse monodromy problems are also considered.Comment: 24 ...

FEBS Letters, EarlyView.This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Infinitesimal deformations of cusp singularities
Proceedings of the Japan Academy, Series A, Mathematical Sciences, 1984 Let (X,0) be a two-dimensional cusp singularity, i.e. a singularity for which the reduced exceptional divisor C in a minimal resolution \(\tilde X\to X\) is a cycle of - say r - rational curves. It is shown that for \(C\cdot C\leq -5\) the dimension of the Zariski tangent space to the base of the semi-universal deformation equals r-C\(\cdot C\).

Deformations of Conically Singular Cayley Submanifolds [PDF]
The Journal of Geometric Analysis, 2018 In this article we study the deformation theory of conically singular Cayley submanifolds. In particular, we prove a result on the expected dimension of a moduli space of Cayley deformations of a conically singular Cayley submanifold. Moreover, when the Cayley submanifold is a two-dimensional complex submanifold of a Calabi--Yau four-fold we show by ...

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

LDAcoop: Integrating non‐linear population dynamics into the analysis of clonogenic growth in vitro
Molecular Oncology, EarlyView.Limiting dilution assays (LDAs) quantify clonogenic growth by seeding serial dilutions of cells and scoring wells for colony formation. The fraction of negative wells is plotted against cells seeded and analyzed using the non‐linear modeling of LDAcoop.
