Single-cell RNAseq reveals seven classes of colonic sensory neuron. [PDF]

, 2018
OBJECTIVE: Integration of nutritional, microbial and inflammatory events along the gut-brain axis can alter bowel physiology and organism behaviour. Colonic sensory neurons activate reflex pathways and give rise to conscious sensation, but the diversity ...

Carrier phase-based ionospheric observables using PPP models

Geodesy and Geodynamics, 2017
The ionosphere is one of the major error sources in Global Navigation Satellite System (GNSS) positioning, navigation and timing. Estimating the ionospheric delays precisely is of great interest in the GNSS community.

A Station-Specific Ionospheric Modeling Method for the Estimation and Analysis of BeiDou-3 Differential Code Bias Parameters

Navigation, 2022
A modified generalized trigonometric series (GTS) function is presented for the joint estimation of local ionospheric activities and differential code biases (DCBs) of the third-generation BeiDou navigation satellite system (BeiDou-3).

Impact of flex power on inter- and intra- differential code bias variation

Geodesy and Geodynamics
Differential Code Bias (DCB) is the time delays between two different GNSS signals, which is crucial for GNSS positioning. Previous studies have shown that it can be significantly affected by the flex power operations in satellites. This study proposes a

Impact of flex power on GPS Block IIF differential code biases [PDF]

, 2020
GPS Block IIF satellites are able to redistribute the transmit power between the signal components. This ability is called Flex power, and it has been developed as a remedy against jamming.

An assessment of the precise products on static Precise Point Positioning using Multi-Constellation GNSS [PDF]

, 2018
Precise point positioning (PPP) is highly dependent on the precise ephemerides and satellite clock products that are used. Different ephemeris and clock products are available from a variety of different organizations.

Debts and experienced financial scarcity: associations with nonsuicidal self‐injury and suicidality in adolescents at risk for psychopathology

Child and Adolescent Mental Health, EarlyView.
Background As adolescents transition to increased independence, they may also begin to encounter financial difficulties, including debt, which may contribute to psychological distress. While financial difficulties and experienced financial scarcity have been well‐documented contributors to suicidality in adults, their impact on adolescent populations ...

Multi-Instrument Observations of a Geomagnetic Storm and its Effects on the Arctic Ionosphere: A Case Study of the 19 February 2014 Storm:Observations of a Geomagnetic Storm [PDF]

, 2017
We present a multiinstrumented approach for the analysis of the Arctic ionosphere during the 19 February 2014 highly complex, multiphase geomagnetic storm, which had the largest impact on the disturbance storm-time index that year.

A Super‐Pangenome for Cultivated Citrus Reveals Evolutive Features During the Allopatric Phase of Their Reticulate Evolution

Plant Biotechnology Journal, EarlyView.
Structure of the cultivated citrus super‐pangenome. ABSTRACT The main genetic diversity observed in cultivated citrus results from a reticulate evolution involving four ancestral taxa whose radiation occurred in allopatry. In such context, GWAS analysis, genome diversity and transcriptomic studies will be significantly enhanced through pangenome ...
