Direct observation of repeated infections with endemic coronaviruses [PDF]
The Journal of Infectious Diseases, 2020 AbstractBackgroundWhile the mechanisms of adaptive immunity to pandemic coronavirus SARS-CoV-2 are still unknown, the immune response to the widespread endemic coronaviruses HKU1, 229E, NL63 and OC43 provide a useful reference for understanding repeat infection risk.MethodsHere we used data from proactive sampling carried out in New York City from fall

A Nearby Repeating Fast Radio Burst in the Direction of M81 [PDF]
The Astrophysical Journal Letters, 2021 Abstract We report on the discovery of FRB 20200120E, a repeating fast radio burst (FRB) with a low dispersion measure (DM) detected by the Canadian Hydrogen Intensity Mapping Experiment FRB project. The source DM of 87.82 pc cm−3 is the lowest recorded from an FRB to date, yet it is significantly higher than the maximum expected from ...

Supporting multiple entanglement flows through a continuous-variable quantum repeater [PDF]
Phys. Rev. A 106, 062611 (2022), 2022 Quantum repeaters are critical to the development of quantum networks, enabling rates of entanglement distribution beyond those attainable by direct transmission. We consider multiple continuous-variable, squeezed light-based entanglement flows through a repeater involving noiseless linear amplification and dual homodyne detection.

Influence of the Approach Direction on the Repeatability of an Industrial Robot [PDF]
Applied Sciences, 2020 The article aims to prove the hypothesis, that an approach direction influences repeatability at target point of a trajectory. Unlike most researches that deal with absolute accuracy, this paper is focused on determining the achievable repeatability and the influence of the direction of approach on it.

PLoS Computational Biology, 2021 Repeat proteins are abundant in eukaryotic proteomes. They are involved in many eukaryotic specific functions, including signalling. For many of these proteins, the structure is not known, as they are difficult to crystallise.

Biomedicines, 2022 Huntington’s Disease (HD) is an autosomal dominant disease that results in severe neurodegeneration with no cure. HD is caused by the expanded CAG trinucleotide repeat (TNR) on the Huntingtin gene (HTT). Although the somatic and germline expansion of the

Reliability and repeatability of ISO 3382-3 metrics based on repeated acoustic measurements in open-plan offices [PDF]
, 2023 This paper investigates variability in the key ISO 3382-3:2012 metrics, based primarily on the repeatability and reliability of these metrics, using repeated measurements in open-plan offices. Two types of repeated measurements were performed in offices, Type1 (n=36), where the same path over workstations was measured from opposite ends, and Type2 (n=7)

Instability of large direct repeats in retrovirus vectors [PDF]
Journal of Virology, 1987 Retrovirus vectors were constructed with large (0.85- to 1.3-kilobase-pair) direct repeats in their genomes. Deletions involving the direct repeats occurred at a high frequency. Deletions occurred both when the direct repeats were in tandem and when they were separated by additional sequences. These deletions occurred during virus replication.
