Insect Molecular Biology, EarlyView.Tomato spotted wilt virus modulated the abundance of gut proteins in larval thrips, most notably manifested as a predominant down‐regulation in first instar larvae. Gut‐expressed protein and cognate transcript abundance were moderately correlated across the tissue system; however, the virus effect varied widely at transcriptional and translational ...

Chain-Level String Topology Operations [PDF]
arXiv, 2015 We construct a space of string diagrams, which are a type of fatgraph with some additional data, and show that there are string topology operations on the chains of the free loop space of a closed Riemannian manifold which are parameterized by the chains on the space of string diagrams.

Molecular Ecology, EarlyView.Abstract Sexual maturation in many fishes requires a major physiological change that involves a rapid transition between energy storage and usage. In Atlantic salmon, this transition for the initiation of maturation is tightly controlled by seasonality and requires a high‐energy status.

Quantum curves as quantum distributions
Journal of High Energy Physics, 2019 Topological strings on toric Calabi-Yau threefolds can be defined non-perturbatively in terms of a non-interacting Fermi gas of N particles. Using this approach, we propose a definition of quantum mirror curves as quantum distributions on phase space ...

Theor.Math.Phys.139:834-845,2004, 2000 We argue that apart from the standard closed and open strings one may consider a third possibility that we call monodromic strings. The monodromic string propagating on a target looks like an ordinary open string (a mapping from a segment to the target) but its space of states is isomorphic to that of a closed string.

Polynomial Rings and Topological Strings
, 2014 An overview is given of the construction of a differential polynomial ring of functions on the moduli space of Calabi-Yau threefolds. These rings coincide with the rings of quasi modular forms for geometries with duality groups for which these are known.

Lectures on Mirror Symmetry and Topological String Theory [PDF]
arXiv, 2012 These are notes of a series of lectures on mirror symmetry and topological string theory given at the Mathematical Sciences Center at Tsinghua University. The N=2 superconformal algebra, its deformations and its chiral ring are reviewed. A topological field theory can be constructed whose observables are only the elements of the chiral ring.

Topological Zero-Thickness Cosmic Strings
, 2007 In this paper, based on the gauge potential decomposition and the $\phi-$mapping theories, we study the topological structures and properties of the cosmic strings that arise in the Abelian-Higgs gauge theory in the zero-thickness limit. After a detailed

Large N instantons from topological strings
SciPost PhysicsThe $1/N$ expansion of matrix models is asymptotic, and it requires non-perturbative corrections due to large $N$ instantons. Explicit expressions for large $N$ instanton amplitudes are known in the case of Hermitian matrix models with one cut, but not ...
