An inhibitory plasticity mechanism for world structure inference by hippocampal replay

Posted by klaurent Columbia

Kavli Affiliate: Attila Losonczy | Authors: Zhenrui Liao, Darian Hadjiabadi, Satoshi Terada, Ivan Soltesz and Attila Losonczy | Summary: Summary Memory consolidation assimilates recent experiences into long-term memory. This process requires the replay of learned sequences, though the content of these sequences remains controversial. Recent work has shown that the statistics of replay deviate from […]

Full forward model of galaxy clustering statistics with AbacusSummit lightcones

Posted by klaurent Stanford

Kavli Affiliate: Tom Abel | First 5 Authors: Sihan Yuan, Boryana Hadzhiyska, Tom Abel, , | Summary: Novel summary statistics beyond the standard 2-point correlation function (2PCF) are necessary to capture the full astrophysical and cosmological information from the small-scale (r < 30Mpc/h) galaxy clustering. However, the analysis of beyond-2PCF statistics on small scales is […]

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 dbos Cornell

Kavli Affiliate: Nicholas L. Abbott | First 5 Authors: Xingzhou Tang, Ali Mozaffari, Noe Atzin, Soumik Das, 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 […]

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 […]
