Subcellular niche segregation of co-obligate symbionts in whiteflies

Kavli Affiliate: Ying Meng | Authors: Akiko FUJIWARA, Xian-Ying Meng, Yoichi Kamagata and Tsutomu TSUCHIDA | Summary: Abstract Many insects contain endosymbiotic bacteria within their bodies. In multiple endosymbiotic systems comprising two or more symbionts, each of the symbionts is generally localized in a different host cell or tissue. Bemisia tabaci (Sweet potato whitefly)possesses a […]

An Information-State Based Approach to Linear Time Varying System Identification and Control

Kavli Affiliate: Ran Wang | First 5 Authors: Mohamed Naveed Gul Mohamed, Raman Goyal, Suman Chakravorty, Ran Wang, | Summary: This paper considers the problem of system identification for linear time varying systems. We propose a new system realization approach that uses an "information-state" as the state vector, where the "information-state" is composed of a […]

Self-regulating surfaces for efficient liquid collection

Kavli Affiliate: Joanna Aizenberg | First 5 Authors: Christian Machado, Yuehan Yao, Emma Feldman, Joanna Aizenberg, Kyoo-Chul Kenneth Park | Summary: To achieve efficient liquid collection, a surface must regulate incoming liquid accumulation with outgoing liquid transport. Often, this can be proposed to be achieved by functionalizing surfaces with non-wetting characteristics. Yet, there remain fundamental, […]

Quadratic computations maintain neural specificity to natural stimuli across stages of visual processing

Kavli Affiliate: Tatyana Sharpee | Authors: Ryan J. Rowekamp and Tatyana Sharpee | Summary: Abstract Despite recent successes in machine vision, artificial recognition systems continue to be less robust than biological systems. The brittleness of artificial recognition system has been attributed to the linearity of the core operation that matches inputs to target patterns at […]

Radiation from Global Topological Strings using Adaptive Mesh Refinement: Massive Modes

Kavli Affiliate: E. P. S. Shellard | First 5 Authors: Amelia Drew, E. P. S. Shellard, , , | Summary: We implement adaptive mesh refinement (AMR) simulations of global topological strings using the public code, GRChombo. We perform a quantitative investigation of massive radiation from single sinusoidally displaced string configurations, studying a range of string […]

Soliton generation in AlGaAs microresonators at room temperature

Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Lue Wu, Weiqiang Xie, Chao Xiang, Lin Chang, Yan Yu | Summary: Chip-integrated optical frequency combs are attractive optical sources in comb applications requiring high-repetition-rate, low power consumption, or compact size. Spontaneous soliton formation via Kerr parametric oscillation is a promising generation principle in these frequency […]

Nonlinear waves at the free surface of flexible mechanical metamaterials

Kavli Affiliate: Katia Bertoldi | First 5 Authors: Bolei Deng, Hang Shu, Jian Li, Chengyang Mo, Jordan R. Raney | Summary: In this letter we investigate the propagation of nonlinear pulses along the free surface of flexible metamaterials based on the rotating squares mechanism. While these metamaterials have previously been shown to support the propagation […]
