The Steady-State Multi-TeV Diffuse Gamma-Ray Emission Predicted with GALPROP and Prospects for the Cherenkov Telescope Array

Posted by klaurent Stanford

Kavli Affiliate: Troy Porter | Summary:Cosmic Rays (CRs) interact with the diffuse gas, radiation, and magnetic fields in the interstellar medium (ISM) to produce electromagnetic emissions that are a significant component of the all-sky flux across a broad wavelength range. The Fermi Large Area Telescope (LAT) has measured these emissions at GeV $γ$-ray energies with […]

Real-space imaging of polar and elastic nano-textures in thin films via inversion of diffraction data

Posted by klaurent Cornell

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Ziming Shao, Noah Schnitzer, Jacob Ruf, Oleg Y. Gorobtsov, Cheng Dai | Summary: Exploiting the emerging nanoscale periodicities in epitaxial, single-crystal thin films is an exciting direction in quantum materials science: confinement and periodic distortions induce novel properties. The structural motifs of interest are ferroelastic, ferroelectric, […]

Generation and propagation of solitary waves in nematic liquid crystals

Posted by klaurent Cornell

Kavli Affiliate: Nicholas L. Abbott | Summary:Solitons in nematic liquid crystals offer intriguing opportunities for transport and sensing in microfluidic systems. Little is known about the elementary conditions that are needed to create solitons in nematic materials. In this work, theory, simulations and experiments are used to study the generation and propagation of solitary waves […]

On codimension one partially hyperbolic diffeomorphisms

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, , , , | Summary: We show that every codimension one partially hyperbolic diffeomorphism must support on $mathbb{T}^{n}$. It is locally uniquely integrable and derived from a linear codimension one Anosov diffeomorphism. Moreover, this system is intrinsically ergodic, and the A. Katok’s conjecture about the […]

Long-Range Repulsion Between Chromosomes in Mammalian Oocyte Spindles

Posted by dbos Harvard

Kavli Affiliate: Daniel J. Needleman | First 5 Authors: Colm P Kelleher, Yash Rana, Daniel J Needleman, , | Summary: During eukaryotic cell division, a microtubule-based structure called the spindle exerts forces on chromosomes, thereby organizing and segregating them Extensive work demonstrates that the forces acting parallel to the spindle axis, including those responsible for […]

The physical basis of self-organization of the mammalian oocyte spindle

Posted by dbos Harvard

Kavli Affiliate: Daniel J. Needleman | First 5 Authors: Colm P Kelleher, Daniel J Needleman, , , | Summary: To prepare gametes with the appropriate number of chromosomes, mammalian oocytes undergo two sequential cell divisions. During each division, a large, long-lived, microtubule-based organelle called the meiotic spindle assembles around condensed chromosomes. Although meiotic spindles have […]

Photonic Elementary Cellular Automata for Simulation of Complex Phenomena

Posted by Caltech

Kavli Affiliate: Alireza Marandi | First 5 Authors: Gordon H. Y. Li, Christian R. Leefmans, James Williams, Alireza Marandi, | Summary: Cellular automata are a class of computational models based on simple rules and algorithms that can simulate a wide range of complex phenomena. However, when using conventional computers, these ‘simple’ rules are only encapsulated […]

A Biophysical Basis for Learning and Transmitting Sensory Predictions

Posted by klaurent Columbia

Kavli Affiliate: Larry Abbott, Nathaniel Sawtell | Authors: Salomon Zev Muller, Larry F Abbott and Nathaniel B Sawtell | Summary: Abstract Homeostatic (anti-Hebbian) forms of synaptic are effective at eliminating “prediction errors” that signal the differences between predicted and actual sensory input. However, such mechanisms appear to preclude the possibility of transmitting the resulting predictions […]
