IEEE Transactions on Smart Grid, 2019 The widely used traditional Kalman filter-type power system dynamic state estimator is unable to address the unknown and non-Gaussian system process and measurement noise as well as dynamical model uncertainties.

NUWA-Infinity: Autoregressive over Autoregressive Generation for Infinite Visual Synthesis [PDF]
Neural Information Processing Systems, 2022 In this paper, we present NUWA-Infinity, a generative model for infinite visual synthesis, which is defined as the task of generating arbitrarily-sized high-resolution images or long-duration videos.

Classical double copy at null infinity [PDF]
Classical and quantum gravity, 2021 We give two double copy prescriptions which construct asymptotically flat solutions in gravity from asymptotically flat gauge fields. The first prescription applies to radiative fields, which are non-linear vacuum solutions determined by characteristic ...

Carrollian manifolds and null infinity: a view from Cartan geometry [PDF]
Classical and quantum gravity, 2021 We discuss three different (conformally) Carrollian geometries and their relation to null infinity from the unifying perspective of Cartan geometry.

Carrollian and celestial spaces at infinity [PDF]
Journal of High Energy Physics, 2021 We show that the geometry of the asymptotic infinities of Minkowski spacetime (in d + 1 dimensions) is captured by homogeneous spaces of the Poincaré group: the blow-ups of spatial (Spi) and timelike (Ti) infinities in the sense of Ashtekar-Hansen and a ...

Asymptotic charges for spin-1 and spin-2 fields at the critical sets of null infinity [PDF]
Journal of Mathematics and Physics, 2021 The asymptotic charges of spin-1 and spin-2 fields are studied near spatial infinity. We evaluate the charges at the critical sets where spatial infinity meets null infinity with the aim of finding the relation between the charges at future and past null

iScience, 2022 Summary: Borna disease viruses (BoDV) have recently emerged as zoonotic neurotropic pathogens. These persistent RNA viruses assemble nuclear replication centers (vSPOT) in close interaction with the host chromatin.

The Holographic Nature of Null Infinity [PDF]
SciPost Physics, 2020 We argue that, in a theory of quantum gravity in a four dimensional asymptotically flat spacetime, all information about massless excitations can be obtained from an infinitesimal neighbourhood of the past boundary of future null infinity and does not ...

BMC Infectious Diseases, 2022 Background The Centers for Disease Control and Prevention contracted with laboratories to sequence the SARS-CoV-2 genome from positive samples across the United States to enable public health officials to investigate the impact of variants on disease ...

Biomedical Journal, 2022 The activity of T cells is finely controlled by a set of negative regulators of T-cell antigen receptor (TCR)-mediated signaling. However, how those negative regulators are themselves controlled to prevent ineffective TCR-mediated responses remain poorly
