This ability corresponds to various forms of vocal production learning that are all possessed by humans and independently displayed by distantly related vertebrates. Among mammals, a few species, including the Egyptian fruit bat, would possess such vocal production learning abilities.

Using optical measures for forecasting algal blooms is a feasible and useful method to overcome these problems. This study explores the potential application of optical measures to enhance algal bloom prediction in terms of prediction accuracy and workload reduction, aided by machine learning (ML) models.

Herein, a porous vanadic oxide-doped cobalt pyrophosphate electrocatalyst, namely VO-CoPO, was exploited by using the electrochemical reconstruction method in the alkaline electrolyte and selecting a cobalt vanadium phosphate Co(HO)(VOPO) as a precursor. The reconstructed vanadic oxide-doped cobalt pyrophosphate catalyst VO-CoPO exhibited efficient electrocatalytic activity for the OER in 1.

It often occurs in greenhouses in winter, with the weak light or hazy weather leading to insufficient photosynthates. The importance of carbohydrate availability in flower retention has been illustrated, while relatively little is understood concerning the mechanism of carbohydrate regulation on flower abscission.

Mutual transformations of various nitrogen compounds and their reaction mechanisms have been a subject of great concern to the chemical, ecological and environmental communities. In the paper, the reactions of ion with small organic acids such as formic acid (HCOOH), acetic acid (CH COOH) and lactic acid (C H O ) under ultraviolet illumination were investigated systematically. It was found that ion is easily reduced into and NO and then further into N and NH (in the form of ) in the process.

After the start-up stage (Days 0-14), the stable operation period was divided into three stages. SO inlet concentration remained 500 mg/m, NO inlet concentrations were 300 mg/m (Days 15-40), 500 mg/m (Days 41-70) and 700 mg/m (Days 71-100).

Nanodots are attractive stimuli-responsive luminescence materials for anti-counterfeiting and information encryption. However, their applications are limited by low water solubility and single-mode information identification by naked eyes under UV light illumination. Herein, we report one type of new nanodots, main-chain imidazolium-based ionic polymer dots (IPDs).
