The arrangement of rays within the phloem and rhytidome was studied in Aesculus stems.It was found that on the cross section most rays in the stem deviate in Z-direction, that is to the right from the geometric radius.The mechanism of Z-arrangement of the rays may be as follows: owing to the action of wind on the crown torques read more arise causi

Abstract Quasi-phase matching (QPM) is a technique extensively utilized in nonlinear optics for enhancing the click here efficiency and stability of frequency conversion processes.However, the conventional QPM relies on periodically poled ferroelectric crystals, which are limited in availability.The 3R phase of molybdenum disulfide (3R-MoS2), a tra

Abstract This work analyses the performance of Reinforcement Learning (RL) versus Swarm Intelligence (SI) for coordinating multiple unmanned High Altitude Platform Stations (HAPS) for communications area coverage.It builds upon previous work which looked at various elements of both algorithms.The main aim of this paper is to address the continuous

There is no leadership without communication.This is especially paramount in hospitals to guarantee optimal processes and teamwork.But do physicians belonging to younger generations, the so-called click here Generation Y, need another approach to leadership and communication? And does the concept of generations stand up to scientific standards? Thi
