Global self$-$similarity of dense granular flow in hopper: the role of hopper width

Kavli Affiliate: Li Xin Li | First 5 Authors: Changhao Li, Xin Li, Xianggui Chen, Zaixin Wang, Min Sun | Summary: The influence of hopper width on the dense granular flow in a two-dimensional hopper is investigated by experiments and simulations. The flow rate remains constant for larger hopper width, while a slight decrease of […]

Hydrogen is not necessary for superconductivity in topotactically reduced nickelates

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Purnima P. Balakrishnan, Dan Ferenc Segedin, Lin Er Chow, P. Quarterman, Shin Muramoto | Summary: A key open question in the study of layered superconducting nickelate films is the role that hydrogen incorporation into the lattice plays in the appearance of the superconducting state. Due to […]

Fabry-Pérot nanocavities controlled by Casimir forces in electrolyte solutions

Kavli Affiliate: Rudolf Podgornik | First 5 Authors: Lixin Ge, Kaipeng Liu, Ke Gong, Rudolf Podgornik, | Summary: We propose a design for tuning the resonant spectra of Fabry-P'{e}rot nanocavities mediated by the Casimir force. The system involves a suspended gold nanoplate approaching to a dielectric-coated gold substrate in a univalent electrolyte solution. The gold […]

A Search for Temporal Atmospheric Variability of Kepler Hot Jupiters

Kavli Affiliate: Avi Shporer | First 5 Authors: Canis Li, Avi Shporer, , , | Summary: We perform a systematic search for atmospheric variability in short-period gas-giant planets (hot Jupiters) observed by the Kepler mission, by looking for temporal variability of their secondary eclipse depths. This is motivated by a recent detection of a decrease […]

Transfer Learning-Enhanced Instantaneous Multi-Person Indoor Localization by CSI

Kavli Affiliate: Yi Zhou | First 5 Authors: Zhiyuan He, Ke Deng, Jiangchao Gong, Yi Zhou, Desheng Wang | Summary: Passive indoor localization, integral to smart buildings, emergency response, and indoor navigation, has traditionally been limited by a focus on single-target localization and reliance on multi-packet CSI. We introduce a novel Multi-target loss, notably enhancing […]

$Γ$-VAE: Curvature regularized variational autoencoders for uncovering emergent low dimensional geometric structure in high dimensional data

Kavli Affiliate: Itai Cohen | First 5 Authors: Jason Z. Kim, Nicolas Perrin-Gilbert, Erkan Narmanli, Paul Klein, Christopher R. Myers | Summary: Natural systems with emergent behaviors often organize along low-dimensional subsets of high-dimensional spaces. For example, despite the tens of thousands of genes in the human genome, the principled study of genomics is fruitful […]
