Measurement incompatibility is a distinguishing property of quantum physics and an essential resource for many information processing tasks. We introduce approach to verify the joint measurability measurements based on phase-space quasiprobability distributions. Our results, therefore, establish connection between two notions nonclassicality, namely negativity distributions measurement incompat...

Fungus-growing ants in the tribe Attini represent a classic example of a mutualism. These ants obligately depend on fungus as their major food source, while the fungus receives both vegetative substrate (nourishment) from the ants and protection from pathogens. Here, we try to identify both benefits and costs of the association by using cultivar switch experiments. We assessed the benefits to e...

Self-incompatibility has been studied by using controlled pollination, pollen tube growth and PCR methods in the Iranian almond ‘Mamaei.’. Pollen tube growth and fruit set following self and cross-pollination treatments were evaluated. The percentage of initial and final fruit set was determined for each treatment at 30 and 60 days after controlled pollination. Pollen germination and pollen ...

The almond, Prunus dulcis Miller which belongs to Rosaceae family, is one of the most important commercial and oldest cultivated tree nut crops. Almonds are classified as a ‘nut’ in which the edible seed is the commercial product. Therefore, pollination and fertilization are necessary in almond. The characteristic of cultivated almond to express gametophytic self- incompatibility discourages se...

In a multidatabase system schematic con icts between two objects are usually of inter est only when the objects have some semantic a nity In this paper we try to reconcile the two perspectives We rst de ne the concept of semantic proximity and provide a semantic taxonomy We then enumerate and classify the schematic and data con icts We discuss possible semantic similarities between two objects ...
