Thermodynamics of light management in near-field thermophotovoltaics
Kavli Affiliate: Eli Yablonovitch | First 5 Authors: Georgia T. Papadakis, Meir Orenstein, Eli Yablonovitch, Shanhui Fan, | Summary: We evaluate near-field thermophotovoltaic (TPV) energy conversion systems focusing in particular on their open-circuit voltage (Voc). Unlike previous analyses based largely on numerical simulations with fluctuational electrodynamics, here, we develop an analytic model that captures the […]

An Information-state based Approach to the Optimal Output Feedback Control of Nonlinear Systems
Kavli Affiliate: Ran Wang | First 5 Authors: , , , , | Summary: This paper develops a data-based approach to the closed-loop output feedback control of nonlinear dynamical systems with a partial nonlinear observation model. We propose an information state based approach to rigorously transform the partially observed problem into a fully observed problem […]

Developmental Stage Classification of Embryos Using Two-Stream Neural Network with Linear-Chain Conditional Random Field
Kavli Affiliate: Daniel Needleman | First 5 Authors: Stanislav Lukyanenko, Won-Dong Jang, Donglai Wei, Robbert Struyven, Yoon Kim | Summary: The developmental process of embryos follows a monotonic order. An embryo can progressively cleave from one cell to multiple cells and finally transform to morula and blastocyst. For time-lapse videos of embryos, most existing developmental […]

Chandra/LETGS Studies of the Collisional Plasma in 4U 1626-67
Kavli Affiliate: Norbert S. Schulz | First 5 Authors: Paul B. Hemphill, Norbert S. Schulz, Herman M. Marshall, Deepto Chakrabarty, | Summary: We present an analysis of chandra/LETGS observations of the ultracompact X-ray binary (UCXB) 4U 1626$-$67, continuing our project to analyze the existing Chandra gratings data of this interesting source. The extremely low mass, […]

Renormalization and non-renormalization of scalar EFTs at higher orders
Kavli Affiliate: Tom Melia | First 5 Authors: Weiguang Cao, Franz Herzog, Tom Melia, Jasper Roosmale Nepveu, | Summary: We renormalize massless scalar effective field theories (EFTs) to higher loop orders and higher orders in the EFT expansion. To facilitate EFT calculations with the R* renormalization method, we construct suitable operator bases using Hilbert series […]

Improving holographic particle characterization by modeling spherical aberration
Kavli Affiliate: Vinothan Manoharan | First 5 Authors: Caroline Martin, Brian Leahy, Vinothan Manoharan, , | Summary: Holographic microscopy combined with forward modeling and inference allows colloidal particles to be characterized and tracked in three dimensions with high precision. However, current models ignore the effects of optical aberrations on hologram formation. We investigate the effects […]

“Worst-Case” Micro-Lensing in the Identification and Modeling of Lensed Quasars
Kavli Affiliate: Paul Schechter | First 5 Authors: Luke Weisenbach, Paul Schechter, Sahil Pontula, , | Summary: Although micro-lensing of macro-lensed quasars and supernovae provides unique opportunities for several kinds of investigations, it can add unwanted and sometimes substantial noise. While micro-lensing flux anomalies may be safely ignored for some observations, they severely limit others. […]
