Cold and transition season cloud condensation nuclei measurements in western Colorado [PDF]

Atmospheric Chemistry and Physics, 2011
Recent studies have shown that orographic precipitation and the water resources that depend on it in the Colorado Rocky Mountains are sensitive to the variability of the region's aerosols, whether emitted locally or from distant sources.

Impact of fragmented urbanization on observed precipitation

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study investigates the impact of fragmented urban landscapes on downwind precipitation by applying an innovative observation‐centered approach to an extensive rain gauge network in Belgium. The approach classifies the observations based on the upwind urban land cover fraction, and compares precipitation indices between rural‐ and urban‐labeled ...

Thermosensitive Nanostructured Coacervates Developed by Mixing ABA‐ and AB‐Block Copolymers and Their Unique Sustained Release of Nano‐Micelles in a Regulated Manner

Small, EarlyView.
Polyion complex micelles composed of blends of ABA and AB block copolymers can form coacervates with a hexagonally packed cylinder nanostructure after heating. The resulting coacervates can release the micelles under physiological conditions in a zero‐order kinetics, possessing cargo proteins.

Kininase I drives angiotensin II‐induced hypertension through activation of the bradykinin B1 receptor

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Kininase I, comprising carboxypeptidase N (CPN) and carboxypeptidase M, regulates kinin activity and is up‐regulated during injury, inflammation and immune activation. Under these conditions, kininase I converts bradykinin and kallidin into des‐Arg kinins, primary endogenous agonists of the bradykinin B1 receptor (R ...

The effects of heating by transported dust layers on cloud and precipitation: a numerical study [PDF]

Atmospheric Chemistry and Physics, 2007
There have been numerous recent publications showing that mineral dust might be a good absorber for solar radiation in addition to its capability to act as cloud condensation nuclei (CCN) and ice forming nuclei (IFN), and could lead to reduced cloud ...

Assessing Desert Dust Indirect Effects on Cloud Microphysics through a Cloud Nucleation Scheme: A Case Study over the Western Mediterranean

Remote Sensing, 2020
In this study, the performance and characteristics of the advanced cloud nucleation scheme of Fountoukis and Nenes, embedded in the fully coupled Weather Research and Forecasting/Chemistry (WRF/Chem) model, are investigated.

Orchestrated molecular changes of proliferative, migratory‐fibrillar, synaptic, and postmigratory compartments align with precocious cortex‐type specification in the early human pallium

Journal of Anatomy, EarlyView.
Early human cortical development is organized by transient cellular compartments that define cortical types before mature layers form. Analysis of the human fetal pallium (7.5–15 PCW) shows distinct spatiotemporal trajectories for the archicortex, mesocortex, and neocortex, with delayed but accelerated differentiation in allocortical regions.

A Microkrystite from the Australasian Tektite/Microtektite Strewn Field

Meteoritics &Planetary Science, EarlyView.
Abstract Microkrystites are glassy impact spherules. They contain primary crystallites carrying information on the physical and chemical conditions prevailing during vaporization, melting, and ejection in large impact cratering events. We report on the geochemistry and mineralogy down to nanometer scale of the first microkrystite (ODP1144A,14) from the

The role of highly oxygenated organic molecules in the Boreal aerosol-cloud-climate system

Nature Communications, 2019
Forests emit compounds into the atmosphere that are oxidized into highly oxygenated molecules that serve as precursors for cloud condensation nuclei–a process that impacts the climate, but is poorly represented in models.

A Three Amino Acid Sequence Gates Protein Stability Control of bHLH104 and Iron Uptake in Arabidopsis thaliana

Plant, Cell &Environment, EarlyView.
ABSTRACT Iron (Fe) homeostasis is regulated to prevent iron imbalance, with the help of redundant basic helix‐loop‐helix (bHLH) IVc transcription factors that can be controlled by Fe‐binding E3 ligases such as BRUTUS (BTS) in Arabidopsis thaliana.
