Developmental Stage Classification of Embryos Using Two-Stream Neural Network with Linear-Chain Conditional Random Field

Posted by dbos July 13, 2021Harvard

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 […]

Learning intermolecular forces at liquid-vapor interfaces

Posted by klaurent July 13, 2021Berkeley

Kavli Affiliate: David T. Limmer | First 5 Authors: Samuel P. Niblett, Mirza Galib, David T. Limmer, , | Summary: By adopting a perspective informed by contemporary liquid state theory, we consider how to train an artificial neural network potential to describe inhomogeneous, disordered systems. We find that neural network potentials based on local representations […]

Quasiparticle kinetic theory for Calogero models

Posted by July 13, 2021Berkeley

Kavli Affiliate: Joel E. Moore | First 5 Authors: Vir B. Bulchandani, Manas Kulkarni, Joel E. Moore, Xiangyu Cao, | Summary: We show that the quasiparticle kinetic theory for quantum and classical Calogero models reduces to the free-streaming Boltzmann equation. We reconcile this simple emergent behaviour with the strongly interacting character of the model by […]

The Subaru HSC weak lensing mass-observable scaling relations of spectroscopic galaxy groups from the GAMA survey

Posted by klaurent July 12, 2021Tokyo

Kavli Affiliate: Masahiro Takada | First 5 Authors: Divya Rana, Surhud More, Hironao Miyatake, Takahiro Nishimichi, Masahiro Takada | Summary: We utilize the galaxy shape catalogue from the first-year data release of the Subaru Hyper Suprime-cam Survey (HSC) to study the dark matter content of galaxy groups in the Universe using weak lensing. We use […]

21cmVAE: A Very Accurate Emulator of the 21-cm Global Signal

Posted by klaurent July 12, 2021Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: Christian H. Bye, Stephen K. N. Portillo, Anastasia Fialkov, , | Summary: Considerable observational efforts are being dedicated to measuring the sky-averaged (global) 21-cm signal of neutral hydrogen from Cosmic Dawn and the Epoch of Reionization. Deriving observational constraints on the astrophysics of this era requires modeling […]

Configuration mixing in strange tetraquarks $Z_{cs}$

Posted by klaurent July 10, 2021Chicago

Kavli Affiliate: Jonathan L. Rosner | First 5 Authors: Marek Karliner, Jonathan L. Rosner, , , | Summary: The BESIII Collaboration has observed a candidate for a $c bar c s bar u$ tetraquark $Z_{cs}$ at $(3982.5^{+1.8}_{-2.6} pm 2.1)$ MeV and width $(12.8^{+5.3}_{-4.4} pm 3.0)$ MeV, while the LHCb Collaboration has observed a $Z_{cs}$ candidate […]

Ultra-low-noise Microwave to Optics Conversion in Gallium Phosphide

Posted by klaurent July 9, 2021Delft

Kavli Affiliate: Simon Groblacher | First 5 Authors: Robert Stockill, Moritz Forsch, Frederick Hijazi, Grégoire Beaudoin, Konstantinos Pantzas | Summary: Mechanical resonators can act as excellent intermediaries to interface single photons in the microwave and optical domains due to their high quality factors. Nevertheless, the optical pump required to overcome the large energy difference between […]

A Large-$N$ Expansion for Minimum Bias

Posted by July 8, 2021Tokyo

Kavli Affiliate: Tom Melia | First 5 Authors: Andrew J. Larkoski, Tom Melia, , , | Summary: Despite being the overwhelming majority of events produced in hadron or heavy ion collisions, minimum bias events do not enjoy a robust first-principles theoretical description as their dynamics are dominated by low-energy quantum chromodynamics. In this paper, we […]

Comparing Supervised Models And Learned Speech Representations For Classifying Intelligibility Of Disordered Speech On Selected Phrases

Posted by klaurent July 8, 2021Harvard

Kavli Affiliate: Michael P. Brenner | First 5 Authors: Subhashini Venugopalan, Joel Shor, Manoj Plakal, Jimmy Tobin, Katrin Tomanek | Summary: Automatic classification of disordered speech can provide an objective tool for identifying the presence and severity of speech impairment. Classification approaches can also help identify hard-to-recognize speech samples to teach ASR systems about the […]
