Rain attenuation time series synthesis with simulated rain cell movement [PDF]

, 2007
This paper proposes a stochastic modeling method to simulate the rain attenuation process in order to generate time series for high frequency terrestrial radio links. It is also the subject of this research to express the local attenuation differences on

Aquatic Diversity and Fishing Practices at Tell Tayinat (Türkiye) in the Iron Age

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT While agrarian societies of the Iron Age Eastern Mediterranean relied predominantly on crops and herding of domestic stock for subsistence, local wild aquatic fauna offered a welcomed enrichment, and when opportunities occurred, it could have been a staple in the human diet.

Rain Rate Measurements & Rain Attenuation Studies at 7 GHz Northern India [PDF]

, 1980
47-51Rain attenuation is an important parameter to be accounted for in tropospheric propagation of frequencies above 10 GHz. But during the monsoon period even lower frequencies around 7 GHz are appreciably affected.

The pistil as a traffic light: Yellow‐to‐red color change likely influences pollinator visitation patterns in Saxifraga fortunei (Saxifragaceae)

PLANTS, PEOPLE, PLANET, EarlyView.
Flowers can communicate reproductive status to pollinators through visual cues. In Saxifraga fortunei, pistils often changed from yellow to red after pollination, and hoverflies and honeybees preferentially visited flowers with yellow pistils. This pattern suggests that a post‐pollination color shift confined to the pistil can reduce revisits to ...

Investigating high altitude platform stations communication in Tanzania under heavy rain conditions

The Journal of Engineering
High altitude platform station (HAPS) is one of the promising solutions to many of the developing and less developed countries. To a great extent, HAPS is relatively cost‐effective and can be easily moved on demand while observing the required quality of

Raindrop size distribution extracted from rain attenuation data [PDF]

, 2008
Attenuation due to rain plays a significant role in the terrestrial and earthspace communication systems especially at frequencies above 10 GHz. Although models proposed by ITU-R for the prediction of rain attenuation give a good estimation about the ...

Botanic and heritage gardens as living laboratories in the age of the polycrisis

PLANTS, PEOPLE, PLANET, EarlyView.
Societal Impact Statement Cities face intertwined crises of climate, biodiversity loss and social disconnection. We show how botanic and heritage gardens can help address these challenges as living laboratories to generate place‐based evidence and public engagement.

The method of intelligent wireless sensor to improve the water permeability of permeable asphalt concrete pavement

IET Networks, EarlyView., 2022
Abstract This research aims to study the intelligent wireless sensor to improve the water permeability of permeable asphalt concrete pavement. The water permeability of pavement is extremely important for the traffic environment. This study first briefly introduces the background and significance analysis, and then exemplifies the deployment algorithm ...

Distracted by a plant: movement of two invasive pentatomids, Halyomorpha halys and Nezara viridula, between companion plants and berry crops

Pest Management Science, EarlyView.
Adult Halyomorpha halys and Nezara viridula rapidly moved between berry crops and companion plants. Habitat use varied across environmental contexts, demonstrating that companion plantings function as dynamic elements in diversified cropping systems. Abstract BACKGROUND The brown marmorated stink bug Halyomorpha halys and the southern green stink bug ...

Reducing copper inputs through integration of essential oil‐based formulations: laboratory and 2‐year vineyard evaluation against Plasmopara viticola

Pest Management Science, EarlyView.
Combining an essential oil (EO)‐based formulation with copper effectively controls Plasmopara viticola. Field trials showed a 92–99% protection with lower copper inputs, achieving a 45% copper reduction without compromising efficacy. This approach supports EO‐based products as sustainable alternatives for grapevine downy mildew management.
