We study patterns of quantum entanglement in systems of spins and ghost-spins regarding them as simple quantum mechanical toy models for theories containing negative norm states.We define a single ghost-spin as in [20] as a 2-state spin variable with an indefinite inner product in the state space.We find that whenever the spin sector is disentangle
In underwater wireless sensor networks (UWSNs), media access control (MAC) is important because it may have a significant impact on network performance; however, the complex and changeable underwater communication environment is a great challenge for the MAC protocol.In flowing water, the network nodes are constantly moving, and the number of compe
Abstract Background Bronchial premalignant lesions (PMLs) are composed primarily of cells resembling basal epithelial cells of the airways, which through poorly understood mechanisms have the potential to progress to lung squamous cell carcinoma (LUSC).Despite ongoing efforts that have mapped gene expression and cell diversity across bronchial PML
The optimal combination of size and shape parameters for classifying structural elements with the lowest percentage error is determined.For this purpose, logical sequences and a series of micrographs of tissues of the pumpkin Cucurbita pepo L.were used to identify and manually classify structural elements into three different classes: cells, interc
Abstract Background It is critical that vector control pesticides are used for their acceptable purpose without causing KRE-ALKALYN adverse effects on health and the environment.This paper provides a global overview of the current status of pesticides management in the practice of vector control.Methods A questionnaire was distributed to WHO member
