The channel matrix of the commonly used uniform circular array-based orbital angular momentum (UCA-OAM) system reaches the full-rank state when the degree of freedom (DoF) is limited only by the number of UCA antenna elements.The rank red pygmy dogwood of the channel matrix of the UCA-OAM system is equal to DoF under this condition.However, the pra

A condition of underdevelopment has marked the kt196 torque converter nations of the Global South since the Second World War.The search for development and for economic growth has made countries in the Global South dependent on global markets and international investment, and have made their environment and nature hostage to capitalist exploration.

With the development of big data and artificial intelligence technologies, the use of computers to assist judgments in legal cases has become a popular topic.Traditional methods for judgment prediction mainly depend on feature models and classification algorithms.However, feature models require considerable expert knowledge and manual annotation wo

In modern aircrafts, hydraulic or pneumatic actuators have been already replaced with electric counterparts, but the advancement of the inverter and motor caruso milk thistle technology has made possible that the propulsion system can be powered by electrical sources.These high power requirements can not be efficiently fulfilled by using a typical

The U.S.military has a need for more powerful propellants with balanced/stoichiometric amounts of fuel and oxidants.However, balanced and more powerful propellants lead to accelerated gun barrel erosion and markedly shortened useful barrel life.Boron nitride (BN) is an interesting potential additive for propellants that could reduce gun wear effect
