Urban horticulture is not as new as many people think.Throughout history, different techniques have been used to ensure sustainable urban agricultural production.A good example of this is the chinampa system, which was developed during the time of the Aztecs in the region of Lake Xochimilco, south of Mexico City.A chinampa is a raised field on a sm
Progress in laser technology has led to very compact but nevertheless powerful laser sources.In the visible and near infrared spectral region, lasers of any wavelength can be purchased.Continuous wave laser sources pose an especially serious threat to the human eye and electro-optical sensors due to their high proliferation and easy availability.Th
The ligand of Numb protein-X (LNX) family, also known as the PDZRN family, is composed of four discrete RING-type E3 ubiquitin ligases (LNX1, LNX2, LNX3, and LNX4), and LNX5 which may not act as an E3 ubiquitin ligase owing to the lack of the RING domain.As the name implies, LNX1 and LNX2 were initially studied for exerting E3 ubiquitin ligase acti
Electromagnetic Boning Knives response of metamaterials is not only determined by its component materials but also the microstructure and arrangements of its resonant elements.The perfect absorber prepared by metamaterial (PMA) can realize 100% absorption in specific frequency bands by designing reasonable structures of resonators.PMA can be applie
Proprotein convertases are enzymes that proteolytically cleave protein precursors in the secretory pathway to yield functional proteins.Seven mammalian subtilisin/Kex2p-like proprotein convertases have been identified: furin, PC1, PC2, PC4, PACE4, PC5 and PC7.The binding pockets of all seven proprotein convertases are evolutionarily conserved and h
