UMBRELLA protocol: systematic reviews of multivariable biomarker prognostic models developed to predict clinical outcomes in patients with heart failure.
(2020)BACKGROUND: Heart failure (HF) is a chronic and common condition with a rising prevalence, especially in the elderly. Morbidity and mortality rates in people with HF are similar to those with common forms of cancer. Clinical ... -
Uncertainties in dynamic response of buildings with non-linear base-isolators
(Elsevier, 2019-08-04)Dynamic response of base-isolated buildings under uni-directional sinusoidal base excitation is numerically investigated considering uncertainties in the isolation and excitation parameters. The buildings are idealized as ... -
Uncertainty relations on nilpotent Lie groups

Unified treatment of synchronization patterns in generalized networks with higher-order, multilayer, and temporal interactions
(Nature Research (part of Springer Nature), 2021)When describing complex interconnected systems, one often has to go beyond the standard network description to account for generalized interactions. Here, we establish a unified framework to simplify the stability analysis ... -
Uniform asymptotics of area-weighted Dyck paths

Uniform Sampling through the Lovász Local Lemma
(Association for Computing Machinery, 2019)We propose a new algorithmic framework, called `"partial rejection sampling'', to draw samples exactly from a product distribution, conditioned on none of a number of bad events occurring. Our framework builds new connections ... -
Uniform semi-Latin squares and their pairwise-variance aberrations
(Elsevier, 2020-12-01)For integers and , an semi-Latin square is an array of -subsets (called blocks) of an -set (of treatments), such that each treatment occurs once in each row and once in each column of the array. A semi-Latin ... -
Universal nonlinear infection kernel from heterogeneous exposure on higher-order networks
(American Physical Society, 2021)The colocation of individuals in different environments is an important prerequisite for exposure to infectious diseases on a social network. Standard epidemic models fail to capture the potential complexity of this scenario ... -
Universal Poisson statistics of a passive tracer diffusing in dilute active suspensions.
(2023-12-12)The statistics of a passive tracer immersed in a suspension of active particles (swimmers) is derived from first principles by considering a perturbative expansion of the tracer interaction with the microscopic swimmer ...
