A calculus for the moduli space of curves [PDF]

open access: yesAlgebraic Geometry, 2016
This article accompanies my lecture at the 2015 AMS summer institute in algebraic geometry in Salt Lake City. I survey the recent advances in the study of tautological classes on the moduli spaces of curves. After discussing the Faber-Zagier relations on

A Statistical Learning Framework for Materials Science: Application to Elastic Moduli of k-nary Inorganic Polycrystalline Compounds

open access: yesScientific Reports, 2016
Materials scientists increasingly employ machine or statistical learning (SL) techniques to accelerate materials discovery and design. Such pursuits benefit from pooling training data across, and thus being able to generalize predictions over, k-nary ...

Flat monodromies and a Moduli Space Size Conjecture [PDF]

open access: yes, 2017
A bstractWe investigate how super-Planckian axions can arise when type IIB 3-form flux is used to restrict a two-axion field space to a one-dimensional winding trajectory.

Relations between static and dynamic moduli of sedimentary rocks

open access: yes, 2019
Static moduli of rocks are usually different from the corresponding dynamic moduli. The ratio between them is generally complex and depends on several conditions, including stress state and stress history. Different drainage conditions, dispersion (often

Moduli vacuum misalignment and precise predictions in string inflation [PDF]

open access: yes, 2016
The predictions for all the cosmological observables of any inflationary model depend on the number of e-foldings which is sensitive to the post-inflationary history of the universe.

Moduli Spaces and Vector Bundles: Geometric Invariant Theory

open access: yes, 2009
In these lectures we will describe a method of constructing quotients in algebraic geometry. The natural context for the construction is that of schemes, but for simplicity we will work always with varieties defined over an algebraically closed field k ...

Uncoupling shear and uniaxial elastic moduli of semiflexible biopolymer networks: compression-softening and stretch-stiffening

open access: yesScientific Reports, 2016
Gels formed by semiflexible filaments such as most biopolymers exhibit non-linear behavior in their response to shear deformation, e.g., with a pronounced strain stiffening and negative normal stress.

Cosmological Moduli and the Post-Inflationary Universe: A Critical Review [PDF]

open access: yes, 2015
We critically review the role of cosmological moduli in determining the post-inflationary history of the universe. Moduli are ubiquitous in string and M-theory constructions of beyond the Standard Model physics, where they parametrize the geometry of the

THE MODULI SPACE OF TWISTED CANONICAL DIVISORS [PDF]

open access: yesJournal of the Institute of Mathematics of Jussieu, 2015
The moduli space of canonical divisors (with prescribed zeros and poles) on nonsingular curves is not compact since the curve may degenerate. We define a proper moduli space of twisted canonical divisors in $\overline{{\mathcal{M}}}_{g,n}$ which includes

Matrigel inhibits elongation and drives endoderm differentiation in aggregates of mouse embryonic stem cells

open access: yesFEBS Open Bio, EarlyView.
Stem cell‐based embryo models (SCBEMs) are valuable to study early developmental milestones. Matrigel, a basement membrane matrix, is a critical substrate used in various SCBEM protocols, but its role in driving stem cell lineage commitment is not clearly defined.
