Development and Preliminary Evaluation of a Machine Vision‐Guided Smart Sprayer Prototype Toward Precision Vegetable Weeding

Journal of Field Robotics, EarlyView.
ABSTRACT Sustainable weed management necessitates herbicide‐reduced, precision weed control. Recent advancements in machine vision and artificial intelligence (AI) for weed recognition and localization have created new opportunities for high‐precision weeding. Although blanket spraying systems are widely used for weed removal, machine vision‐guided, AI‐

Identifying Urban Sources as Cause of Elevated Grass Pollen Concentrations using GIS and Remote Sensing [PDF]

, 2013
We examine here the hypothesis that during flowering, the grass pollen concentrations at a specific site reflect the distribution of grass pollen sources within a few kilometres of this site.We perform this analysis on data from a measurement campaign in

Ant–aphid mutualism: the influence of Tapinoma ibericum (Hymenoptera: Formicidae) on Aphis gossypii (Hemiptera: Aphidae) control by commercial and spontaneous natural enemies

Insect Science, EarlyView.
The mutualism between Tapinoma ibericum ants and Aphis gossypii disrupts the biological control exerted by Aphidius colemani in greenhouse peppers. Ant exclusion increased parasitism and the presence of most natural enemies, although Aphidoletes aphidimyza was more abundant with ants.

Efficacy of House Dust Mite Immunotherapy in Chinese Allergic Rhinitis Patients With Diverse Sensitization Patterns: A Multicenter Study (COVER Study)

Allergy, EarlyView.
This prospective multicenter study corroborates the efficacy of AIT with the native HDM allergen extract in Chinese AR patients with diverse HDM sensitization patterns. HDM sensitization pattern affects the efficacy of AIT, with patients sensitized to both major and minor allergens of HDM showing improved outcomes with HDM SCIT.

Five‐Grass‐Pollen Sublingual Immunotherapy Drops Are Efficacious and Well Tolerated in Adults: The RHAPSODY Phase III Trial

Allergy, EarlyView.
The RHAPSODY multinational study investigated 26 months of continuous treatment with 5‐grass‐pollen sublingual SLIT drops in adults with moderate‐to‐severe grass‐pollen‐induced allergic rhinoconjunctivitis. The primary efficacy endpoint (the average daily total combined score) showed statistically significant differences in favour of the active ...

Early Competitive Effects of Common Ragweed (Ambrosia artemisiifolia L.) on Oilseed Rape (Brassica napus L.) Revealed by Non-Invasive Stress Indicators

Agriculture
Climate change reshapes crop–weed interactions and challenges the cultivation of oilseed rape (Brassica napus L.). Common ragweed (Ambrosia artemisiifolia L.) strongly suppresses early crop development, increases stress sensitivity and leads to yield ...
