Enhancing diffusion models with Gaussianization preprocessing
Li Cunzhi, Louis Kang, Hideaki Shimazaki
Diffusion models are a class of generative models that have demonstrated remarkable success in tasks such as image generation. However, one of the bottlenecks of these models is sl…
Control of seizure-like dynamics in neuronal populations with excitability adaptation related to ketogenic diet
Sebastian Eydam, Igor Franović, Louis Kang
We consider a heterogeneous, globally coupled population of excitatory quadratic integrate-and-fire neurons with excitability adaptation due to a metabolic feedback associated with…
A Hopfield-like model with complementary encodings of memories
Louis Kang, Taro Toyoizumi
We present a Hopfield-like autoassociative network for memories representing examples of concepts. Each memory is encoded by two activity patterns with complementary properties. Th…
A geometric attractor mechanism for self-organization of entorhinal grid modules
Louis Kang, Vijay Balasubramanian
Grid cells in the medial entorhinal cortex (MEC) respond when an animal occupies a periodic lattice of "grid fields" in the environment. The grids are organized in modules with spa…
Chiral twist drives raft formation and organization in membranes composed of rod-like particles
Louis Kang, T. C. Lubensky
Lipid rafts are hypothesized to facilitate protein interaction, tension regulation, and trafficking in biological membranes, but the mechanisms responsible for their formation and…
Entropic forces stabilize diverse emergent structures in colloidal membranes
Louis Kang, Thomas Gibaud, Zvonimir Dogic +1
The depletion interaction mediated by non-adsorbing polymers promotes condensation and assembly of repulsive colloidal particles into diverse higher-order structures and materials.…
Chiral structures and defects of lyotropic chromonic liquid crystals induced by saddle-splay elasticity
Zoey S. Davidson, Louis Kang, Joonwoo Jeong +4
An experimental and theoretical study of lyotropic chromonic liquid crystals (LCLCs) confined in cylinders with degenerate planar boundary conditions elucidates LCLC director confi…
The syncytial Drosophila embryo as a mechanically excitable medium
Timon Idema, Julien O. Dubuis, Louis Kang +4
Mitosis in the early syncytial Drosophila embryo is highly correlated in space and time, as manifested in mitotic wavefronts that propagate across the embryo. In this paper we inve…
Adaptation through stochastic switching into transient mutators in finite asexual populations
Muyoung Heo, Louis Kang, Eugene Shakhnovich
The importance of mutator clones in the adaptive evolution of asexual populations is not fully understood. Here we address this problem by using an ab initio microscopic model of l…
Emergence of species in evolutionary simulated annealing
Muyoung Heo, Louis Kang, Eugene I. Shakhnovich
Which factors govern the evolution of mutation rates and emergence of species? Here, we address this question using a first principles model of life where population dynamics of as…
