The Infrared Medium-deep Survey. IX. Discovery of Two New $zsim6$ Quasars and Space Density down to $M_{1450}sim-23.5$ mag

Posted by klaurent July 25, 2022Peking

Kavli Affiliate: Linhua Jiang | First 5 Authors: Yongjung Kim, Myungshin Im, Yiseul Jeon, Minjin Kim, Linhua Jiang | Summary: We present the result of the Infrared Medium-deep Survey (IMS) $zsim6$ quasar survey, using the combination of the IMS near-infrared images and the Canada-France-Hawaii Telescope Legacy Survey (CFHTLS) optical images. The traditional color-selection method results […]

A measurement of the mean central optical depth of galaxy clusters via the pairwise kinematic Sunyaev-Zel’dovich effect with SPT-3G and DES

Posted by July 25, 2022Stanford

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: E. Schiappucci, F. Bianchini, M. Aguena, M. Archipley, L. Balkenhol | Summary: We infer the mean optical depth of a sample of optically-selected galaxy clusters from the Dark Energy Survey (DES) via the pairwise kinematic Sunyaev-Zel’dovich (kSZ) effect. The pairwise kSZ signal between pairs of clusters drawn […]

Highly non-Gaussian tails and primordial black holes from single-field inflation

Posted by klaurent July 25, 2022Tokyo

Kavli Affiliate: Misao Sasaki | First 5 Authors: Yi-Fu Cai, Xiao-Han Ma, Misao Sasaki, Dong-Gang Wang, Zihan Zhou | Summary: For primordial perturbations, deviations from Gaussian statistics on the tail of the probability distribution can be associated with non-perturbative effects of inflation. In this paper, we present some particular examples in which the tail of […]

Salient Object Detection for Point Clouds

Posted by July 25, 2022Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: Songlin Fan, Wei Gao, Ge Li, , | Summary: This paper researches the unexplored task-point cloud salient object detection (SOD). Differing from SOD for images, we find the attention shift of point clouds may provoke saliency conflict, i.e., an object paradoxically belongs to salient and non-salient categories. […]

Coupled charge and energy transfer dynamics in light harvesting complexes from a hybrid hierarchical equations of motion approach

Posted by klaurent July 24, 2022Berkeley

Kavli Affiliate: David T. Limmer | First 5 Authors: Thomas P. Fay, David T. Limmer, , , | Summary: We describe a method for simulating exciton dynamics in protein-pigment complexes, including effects from charge transfer as well as fluorescence. The method combines the hierarchical equations of motion, which are used to describe quantum dynamics of […]

Model-based Unbiased Learning to Rank

Posted by klaurent July 24, 2022Cornell

Kavli Affiliate: Dan Luo | First 5 Authors: Dan Luo, Lixin Zou, Qingyao Ai, Zhiyu Chen, Dawei Yin | Summary: Unbiased Learning to Rank~(ULTR) that learns to rank documents with biased user feedback data is a well-known challenge in information retrieval. Existing methods in unbiased learning to rank typically rely on click modeling or inverse […]

Learning Dynamic Facial Radiance Fields for Few-Shot Talking Head Synthesis

Posted by klaurent July 24, 2022UCAS

Kavli Affiliate: Zheng Zhu | First 5 Authors: Shuai Shen, Wanhua Li, Zheng Zhu, Yueqi Duan, Jie Zhou | Summary: Talking head synthesis is an emerging technology with wide applications in film dubbing, virtual avatars and online education. Recent NeRF-based methods generate more natural talking videos, as they better capture the 3D structural information of […]

Relative baryon-dark matter velocities in cosmological zoom simulations

Posted by klaurent July 23, 2022Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: Luke Conaboy, Ilian T. Iliev, Anastasia Fialkov, Keri L. Dixon, David Sullivan | Summary: Supersonic relative motion between baryons and dark matter due to the decoupling of baryons from the primordial plasma after recombination affects the growth of the first small-scale structures. Large box sizes (greater than […]

Cortical surface electrical potentials are composed of multiple bandlimited frequency components, including high-gamma

Posted by klaurent July 23, 2022August 1, 2022UCSF

Kavli Affiliate: Kristofer Bouchard, Edward Chang | Authors: Jesse A Livezey, Ahyeon Hwang, Kseniya Usovich, Maximilian Dougherty, Edward F Chang and Kristofer E Bouchard | Summary: A common challenge in neuroscience is how to decompose noisy, multi-source signals measured in experiments into biophysically interpretable components. Analysis of cortical surface electrical potentials (CSEPs) measured using electrocorticography […]
