Modular forms and SL(2, ℤ)-covariance of type IIB superstring theory
Abstract: The local higher-derivative interactions that enter into the low-energy expansion of the effective action of type IIB superstring theory with constant complex modulus generally violate the U(1) R-symmetry of IIB...

Two-dimensional electron gas at the PbTi O3/SrTi O3 interface
In the polar catastrophe scenario, polar discontinuity accounts for the driving force of the formation of a two-dimensional electron gas (2DEG) at the interface between polar and nonpolar insulators. In this paper, we substitute...
Cryo-EM Structures of MDA5-dsRNA Filaments at Different Stages of ATP Hydrolysis.
Double-stranded RNA (dsRNA) is a potent proinflammatory signature of viral infection. Long cytosolic dsRNA is recognized by MDA5. The cooperative assembly of MDA5 into helical filaments on dsRNA nucleates the assembly of a...

Characterization of universal features of partially methylated domains across tissues and species.
Benjamin E Decato, Jianghan Qu, Xiaojing Ji, Elvin Wagenblast, Simon RV Knott, Gregory J Hannon, Andrew D Smith
Dec 14, 2020
BACKGROUND: Partially methylated domains (PMDs) are a hallmark of epigenomes in reproducible and specific biological contexts, including cancer cells, the placenta, and cultured cell lines. Existing methods for deciding whether...
Monocular Depth Matching With Hybrid Sampling and Depth Label Propagation
This paper proposes a monocular depth label propagation model, which describes monocular images into depth label distribution for the target classification matching. 1) Depth label propagation by hybrid sampling and salient...

Ultra-high repetition rate absorption spectroscopy with low noise supercontinuum radiation generated in an all-normal dispersion fibre
S. Dupont, Z. Qu, S.-S. Kiwanuka, L.E. Hooper, J.C. Knight, S.R. Keiding, C.F. Kaminski
May 09, 2014
We report the use of a dispersed supercontinuum generated in an all-normal-dispersion fibre to record low-noise spectra from atmospheric molecules at least an order of magnitude faster than has been previously reported....
