Precision planter monitoring system based on mobile communication network
IET Networks, EarlyView., 2022 Abstract Sowing is an important link in agricultural production and the basis for ensuring high yields and bumper harvests. Agriculture requires precision plows with good performance and stable work. However, the seeding process is in a completely closed state, and the operator relies mainly on experience to judge the operating state and performance of

Ungulates’ Behavioral Responses to Humans as an Apex Predator in a Hunting-Prohibited Area of China
Animals, 2023 Large mammals can perceive humans as predators and therefore adjust their behavior to achieve coexistence with humans. However, lack of research at sites with low hunting intensity limits our understanding of how behavioral responses of animals adapt to ...

Reverberant Sound Field Equalisation for an Enhanced Stereo Playback Experience
Proceedings of the 10th Convention of the European Acoustics Association Forum Acusticum 2023, 2022 The topic of room equalisation has been at the forefront of research and product development for many years, with the aim of increasing the playback quality of loudspeakers in reverberant rooms. Traditional room equalisation systems comprise of a number of filters that when applied to the primary loudspeakers, additional room colouration is compensated

Two novel vocalizations are used by veeries (Catharus fuscescens) during agonistic interactions.
PLoS ONE, 2015 Avian vocalizations are common examples of the complex signals used by animals to negotiate during agonistic interactions. In this study, we used two playback experiments to identify agonistic signals in a songbird species with several acoustically ...

Structural-functional characteristics of two song types in Phylloscopus humei (Phylloscopidae)
Nature Conservation Research: Заповедная наука, 2023 Several songbird species use two singing modes, which are functionally different. The first mode is preferentially used at the beginning of the breeding cycle, and serves to attract females, while the second mode is used later in the season as well as ...

Difficulties when using video playback to investigate social cognition in California scrub-jays (Aphelocoma californica) [PDF]
PeerJ, 2018 Previous research has suggested that videos can be used to experimentally manipulate social stimuli. In the present study, we used the California scrub-jays’ cache protection strategies to assess whether video playback can be used to simulate ...
