Proximal Molecular Probe Transfer (PROMPT), a new approach for identifying sites of protein/nucleic acid interaction in cells by correlated light and electron microscopy

Posted by klaurent UCSD / Salk

Kavli Affiliate: Mark Ellisman | Authors: Guillaume A Castillon, Sebastien Phan, Junru Hu, Daniela Boassa, Stephen R Adams and Mark H Ellisman | Summary: The binding and interaction of proteins with nucleic acids such as DNA and RNA constitutes a fundamental biochemical and biophysical process in all living organisms. Identifying and visualizing such temporal interactions […]

POEMMA (Probe of Extreme Multi-Messenger Astrophysics) Roadmap Update

Posted by klaurent Chicago

Kavli Affiliate: Angela V. Olinto | First 5 Authors: Angela V. Olinto, , , , | Summary: The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) was designed as a NASA Astrophysics probe-class mission to identify the sources of ultrahigh energy cosmic rays (UHECRs) and observe cosmic neutrinos from extremely energetic transient sources. POEMMA consists of two […]

Host–pathogen–vector continuum in a changing landscape: Drivers of Bartonella prevalence and evidence of historic spillover in a tropical multi–host community

Posted by klaurent UCSD / Salk

Kavli Affiliate: V. S. Ramachandran | Authors: B.R. Ansil, Ashwin Viswanathan, Vivek Ramachandran, H.M. Yeshwanth, Avirup Sanyal and Uma Ramakrishnan | Summary: Our understanding of pathogen spillover is largely based on viral systems associated with bats. Bacterial infections of zoonotic origin also pose a significant public health burden, many of which are associated with small […]

Geometric frustration of hard-disk packings on cones

Posted by klaurent Harvard

Kavli Affiliate: Vinothan N. Manoharan | First 5 Authors: Jessica H. Sun, Abigail Plummer, Grace H. Zhang, David R. Nelson, Vinothan N. Manoharan | Summary: Conical surfaces pose an interesting challenge to crystal growth: a crystal growing on a cone can wrap around and meet itself at different radii. We use a disk-packing algorithm to […]

Dualities and Discretizations of Integrable Quantum Field Theories from 4d Chern-Simons Theory

Posted by klaurent Tokyo

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Meer Ashwinkumar, Jun-ichi Sakamoto, Masahito Yamazaki, , | Summary: We elucidate the relationship between 2d integrable field theories and 2d integrable lattice models, in the framework of the 4d Chern-Simons theory. The 2d integrable field theory is realized by coupling the 4d theory to multiple 2d surface […]

Universal Gravitational Waves from Interacting and Clustered Solitons

Posted by klaurent Tokyo

Kavli Affiliate: Misao Sasaki | First 5 Authors: Kaloian D. Lozanov, Misao Sasaki, Volodymyr Takhistov, , | Summary: Causal soliton formation (e.g. oscillons, Q-balls) in the primordial Universe is expected to give rise to a universal gravitational wave (GW) background, at frequencies smaller than scales of nonlinearity. We show that modifications of the soliton density […]

Hybrid Strangeon Stars

Posted by klaurent Peking

Kavli Affiliate: Renxin Xu | First 5 Authors: Chen Zhang, Yong Gao, Cheng-Jun Xia, Renxin Xu, | Summary: It was conjectured that the basic units of the ground state of bulk strong matter may be strange-clusters called strangeons, and they can form self-bound strangeon stars that are highly compact. Strangeon stars can develop a strange […]

Second-order optical response of superconductors induced by supercurrent injection

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Linghao Huang, Jing Wang, , , | Summary: We develop a theory of the nonlinear optical responses in superconducting systems in the presence of a dc supercurrent. The optical transitions between particle-hole pair bands across the superconducting gap are allowed in clean superconductors as the inversion-symmetry-breaking by […]
