Stochastic gravitational wave background from supernovae in massive scalar-tensor gravity

Kavli Affiliate: Ulrich Sperhake | Summary:In massive scalar-tensor gravity, core-collapse supernovae are strong sources of scalar-polarized gravitational waves. These can be detectable out to large distance. The dispersive nature of the propagation of waves in the massive scalar field mean the gravitational wave signals are long lived and many such signals can overlap to form […]

A quick and cost-effective method for DNA-free total RNA isolation using magnetic silica beads

Kavli Affiliate: Aniruddha Das | Authors: Aniruddha Das, Debojyoti Das, Arundhati Das and Amaresh Chandra Panda | Summary: Current RNA purification methods widely use silica-based columns that allow quick isolation of high-quality and good quantities of RNA. However, the major limitations include high cost, the requirement of different kits for small RNA isolation, genomic DNA […]

Reconstruction of a surface from the category of reflexive sheaves

Kavli Affiliate: Alexey Bondal | Summary:We define a normal surface $X$ to be codim-2-saturated if any open embedding of $X$ into a normal surface with the complement of codimension 2 is an isomorphism. We show that any normal surface $X$ allows a codim-2-saturated model $widehatX$ together with the canonical open embedding $Xto widehatX$. Any normal […]

Modeling the Galaxy Distribution in Clusters using Halo Cores

Kavli Affiliate: Salman Habib | First 5 Authors: Danila Korytov, Esteban Rangel, Lindsey Bleem, Nicholas Frontiere, Salman Habib | Summary: The galaxy distribution in dark matter-dominated halos is expected to approximately trace the details of the underlying dark matter substructure. In this paper we introduce halo `core-tracking’ as a way to efficiently follow the small-scale […]

Variational Tensor Wavefunctions for the Interacting Quantum Spin Hall Phase

Kavli Affiliate: Shenghan Jiang | Summary:The quantum spin hall (QSH) phase, also known as the 2D topological insulator, is characterized by protected helical edge modes arising from time reversal symmetry. While initially proposed for band insulators, this phase can also manifest in strongly-correlated systems where conventional band theory fails. To overcome the challenge of simulating […]

Flexible Phased Array Sheets: A Techno-Economic Analysis

Kavli Affiliate: Ali Hajimiri | Summary:Phased arrays have enabled advances in communications, sensing, imaging, and wireless power transfer. In all these applications, large apertures enable higher power, higher data rates, higher resolution, and complex functionalities, but are elusive owing to a correspondingly large cost, mass, and physical size. Flexible phased arrays (FPAs) show potential in […]

Standing genetic variation and chromosome differences drove rapid ecotype formation in a major malaria mosquito

Kavli Affiliate: Scott Small | Authors: Scott T. Small, Carlo Costantini, N’Fale Sagnon, Moussa W. Guelbeogo, Scott J. Emrich, Andrew D. Kern, Michael C. Fontaine and Nora J. Besansky | Summary: Species distributed across heterogeneous environments often evolve locally adapted ecotypes, but understanding of the genetic mechanisms involved in their formation and maintenance in the […]
