Advanced Science, EarlyView.The genome of Megachile rotundata, an extensively managed solitary pollination bee species, has been sequenced, covering 280.68 Mb and predicting 10 701 genes. The study reveals significant expansions of the Toll gene family and their abundant expression in diapause prepupae, highlighting enhanced immune responses during diapause. This genome serves as

Weakly Supervised Attention-based Models Using Activation Maps for Citrus Mite and Insect Pest Classification [PDF]
arXiv, 2021 Citrus juices and fruits are commodities with great economic potential in the international market, but productivity losses caused by mites and other pests are still far from being a good mark. Despite the integrated pest mechanical aspect, only a few works on automatic classification have handled images with orange mite characteristics, which means ...

Advanced Energy Materials, EarlyView.Formamidinium‐based perovskite (FAPbI3) solar cells are of great interest due to an advantageous band gap able to achieve the maximum theoretical efficiency. In this study, a strategy is demonstrated based on a halide ion gradient (present in the general 2D perovskite formulation) created on the 3D FAPbI3 surface to simultaneously increase the ...

Using Transfer Learning for Image-Based Cassava Disease Detection [PDF]
Frontiers in Plant Science 2017 vol. 8 p. 1852, 2017 Cassava is the third largest source of carbohydrates for human food in the world but is vulnerable to virus diseases, which threaten to destabilize food security in sub-Saharan Africa. Novel methods of cassava disease detection are needed to support improved control which will prevent this crisis.

Population dynamics of Varroa mite and honeybee: Effects of parasitism with age structure and seasonality [PDF]
arXiv, 2020 Honeybees play an important role in the production of many agricultural crops and in sustaining plant diversity in undisturbed ecosystems. The rapid decline of honeybee populations have sparked great concern worldwide. Previous studies have shown that the parasitic Varroa mite could be the main reason for colony losses. In order to understand how mites

Sorting of Chiral Microswimmers [PDF]
Soft Matter 9, 6347-6542, 2013, 2012 Microscopic swimmers, e.g., chemotactic bacteria and cells, are capable of directed motion by exerting a force on their environment. For asymmetric microswimmers, e.g., bacteria, spermatozoa and many artificial active colloidal particles, a torque is also present leading in two dimensions to circular motion and in three dimensions to helicoidal motion ...
