Nuclear DNA replication in Leishmania major relies on a single constitutive origin per chromosome supplemented by thousands of stochastic initiation events

Posted by dbos UCSD / Salk

Kavli Affiliate: Gabriel Silva | Authors: Jeziel D Damasceno, Gabriel LA Silva, Catarina A Marques, Marija Krasilnikova, Craig Lapsley, Dario Beraldi and Richard McCulloch | Summary: Understanding genome duplication requires characterisation of the locations where DNA replication initiates, termed origins. Genome-wide mapping of DNA replication origins has mainly been derived from population-based techniques, with only […]

Coherent Magneto-Conductance Oscillations in Amorphous Topological Insulator Nanowires

Posted by dbos Berkeley

Kavli Affiliate: Joel E. Moore | First 5 Authors: Siddhant Mal, Elizabeth J. Dresselhaus, Joel E. Moore, , | Summary: Recent experiments on amorphous materials have established the existence of surface states similar to those of crystalline three-dimensional topological insulators (TIs). Amorphous topological insulators are also independently of interest for thermo-electric and other properties. To […]

Tidally distorted stars are triaxial pulsators

Posted by dbos MIT

Kavli Affiliate: Saul Rappaport | First 5 Authors: Jim Fuller, Saul Rappaport, Rahul Jayaraman, Don Kurtz, Gerald Handler | Summary: Stars in close binaries are tidally distorted, and this has a strong effect on their pulsation modes. We compute the mode frequencies and geometries of tidally distorted stars using perturbation theory, accounting for the effects […]

2D Theoretically Twistable Material Database

Posted by dbos Cornell

Kavli Affiliate: Jie Shan | First 5 Authors: Yi Jiang, Urko Petralanda, Grigorii Skorupskii, Qiaoling Xu, Hanqi Pi | Summary: The study of twisted two-dimensional (2D) materials, where twisting layers create moir’e superlattices, has opened new opportunities for investigating topological phases and strongly correlated physics. While systems such as twisted bilayer graphene (TBG) and twisted […]

Diffusive dynamics of charge regulated macro-ion solutions

Posted by dbos UCAS

Kavli Affiliate: Rudolf Podgornik | First 5 Authors: Bin Zheng, Shigeyuki Komura, David Andelman, Rudolf Podgornik, | Summary: Onsager’s variational principle is generalized to address the diffusive dynamics of an electrolyte solution composed of charge-regulated macro-ions and counterions. The free energy entering the Rayleighian corresponds to the Poisson-Boltzmann theory augmented by the charge-regulation mechanism. The […]

Cancelling mod-2 anomalies by Green-Schwarz mechanism with $B_{μν}$

Posted by dbos Tokyo

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Shota Saito, Yuji Tachikawa, , , | Summary: We study if and when mod-2 anomalies can be canceled by the Green-Schwarz mechanism with the introduction of an antisymmetric tensor field $B_{munu}$. As explicit examples, we examine $SU(2)$ and more general $Sp(n)$ gauge theories in four and eight […]

Solving the Inverse Band-Structure Problem for Photonic Crystals

Posted by dbos Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Aditya Bahulikar, Feng Wang, Mustafa Cenk Gursoy, Rodrick Kuate Defo, | Summary: We present a symmetry-agnostic topology optimization framework for photonic-crystal structures based on computation of the photonic density of states in a manner analogous to $Gamma$-point integration. We provide a generalization of the approach that allows […]

Coherently Coupled Carrier and Phonon Dynamics in Elemental Tellurium Probed by Few-Femtosecond Core-Level Transient Absorption

Posted by dbos Berkeley

Kavli Affiliate: Peidong Yang | First 5 Authors: Jonah R. Adelman, Hugo Laurell, Lorenz Drescher, Han K. D. Le, Peidong Yang | Summary: The narrow bandgap semiconductor elemental tellurium (Te) has a unique electronic structure due to strong spin-orbit splitting and a lack of inversion symmetry of its helical lattice. Using broadband extreme ultraviolet core-level […]
