Two-Dimensional Simulation of Barley Growth and Yield Using a Model Integrated with Remote-Controlled Aerial Imagery

open access: yesRemote Sensing, 2020
It is important to be able to predict the yield and monitor the growth conditions of crops in the field to increase productivity. One way to assess field-based geospatial crop productivity is by integrating a crop model with a remote-controlled aerial ...

Inter‐Crystal Spacing of Implantable Polymeric Surfaces as a Key Suppressor of Microbial Adhesion.

open access: yesSmall, EarlyView.
Biofilm formation on implantable devices is addressed by controlling inter‐crystal spacing in shape memory polymers. Repeated shape recovery aligns and enlarges crystalline phases and reduces amorphous regions, enhancing bacterial repellency. Three biofilm‐forming bacteria show reduced adhesion, and a one‐year dog bile‐duct model maintains function ...

Potential of Regional Ionosphere Prediction Using a Long Short‐Term Memory Deep‐Learning Algorithm Specialized for Geomagnetic Storm Period

open access: yesSpace Weather, 2021
In our previous study (Moon et al., 2020, https://doi.org/10.3938/jkps.77.1265), we developed a long short‐term memory (LSTM) deep‐learning model for geomagnetic quiet days (LSTM‐quiet) to perform effective long‐term predictions for the regional ...

In Situ Surface Reconstruction and Carbon Encapsulation for High‐Performance Pt‐Lean Catalysts beyond Conventional Core–Shell Designs

open access: yesSmall, EarlyView.
A one‐step in situ fabrication produces Pt‐segregated nanoparticles encapsulated in porous carbon shells. This design drastically reduces Pt content while maintaining high oxygen reduction reaction activity and long‐term durability. The catalyst meets DOE targets even at ultralow Pt loading, presenting a practical pathway toward cost‐effective, high ...

Mapping resistance responses to Sclerotinia infestation in introgression lines of Brassica juncea carrying genomic segments from wild Brassicaceae B. fruticulosa

open access: yesScientific Reports, 2017
Sclerotinia stem rot (Sclerotinia sclerotiorum) is a major disease of Brassica oilseeds. As suitable donors to develop resistant cultivars are not available in crop Brassicas, we introgressed resistance from a wild Brassicaceae species, B.

On the nonuniform Berry--Esseen bound [PDF]

open access: yes, 2013
Due to the effort of a number of authors, the value c_u of the absolute constant factor in the uniform Berry--Esseen (BE) bound for sums of independent random variables has been gradually reduced to 0.4748 in the iid case and 0.5600 in the general case ...

The Selection of Tenured Astronomers in France

open access: yes, 2003
The organization of the recruitment of tenured astronomers and astrophysicists in France is presented and compared with the setup in other countries. The ages for getting tenure have increased from 27-28 in 1980 to 31 today. Foreign scientists constitute

Relationships between chick vocalizations and parental absence in Kentish Plovers

open access: yesIbis, EarlyView.
Chick calls within bird species vary greatly, often in relation to whether parents are present. We studied chick calls in a nidifugous shorebird, the Kentish Plover Anarhynchus alexandrinus, in three circumstances—(1) on the nest with parental presence; (2) on the nest with parental absence; and (3) out‐of‐nest with human observer presence—and ...

Sediment transport and depositional hydrodynamics on the eastern Korean continental margin revealed by surface sediment granulometry

open access: yesSedimentology, EarlyView.
ABSTRACT Terrigenous sediments are transported from coastal areas and shelves to deeper continental margins by multiple processes. Understanding these processes is critical for evaluating the ecological impacts of fine‐grained sediment deposition and predicting future changes in sediment dispersal under rapid climate change.

SnO2 nanostructure-based acetone sensors for breath analysis

open access: yesMicro and Nano Systems Letters
The World Health Organization reports that metabolic disorders are responsible for a significant proportion of global mortality. Considering this, breath sensors have gained prominence as effective tools for monitoring and diagnosing metabolic disorders,
