A Leslie-Gower predator-prey model incorporating harvesting is studied. By constructing a suitable Lyapunov function, we show that the unique positive equilibrium of the system is globally stable, which means that suitable harvesting has no influence on the persistent property of the harvesting system. After that, detailed analysis about the influence of harvesting is carried out, and an intere...

The light-harvesting complex II (LHCII) is the main energy absorber for photosynthesis in green plants, and its translocation between photosystems I and II is the primary means of energy redistribution between them. Using single-particle tracking, we performed the first measurement of the mobility of LHCII in the photosynthetic membranes in both the nonphosphorylated and the phosphorylated (P-L...

Studies on harvesting robots with manipulator were started with the tomato fruit harvesting robot since 30 years ago by Prof. Kawamura, Kyoto University [1]. The robot consisted of a 5 DOF manipulator, a harvesting end-effector, a color TV camera which was used for stereo vision, and a battery car for traveling in the ridges as shown in Figure 1. Following the harvesting robot, the robotic tech...

When exposed to excess light illumination photosynthetic organisms switch into a photoprotective quenched state where the excess energy is safely dissipated as heat. When these processes are investigated by means of ultrafast spectroscopy, the experimentalist is faced with the unnatural process of singlet–singlet annihilation which often makes the interpretation of the results very complicated....

The light-harvesting antenna of photosystem II (PSII) has the ability to switch rapidly between a state of efficient light use and one in which excess excitation energy is harmlessly dissipated as heat, a process known as qE. We investigated the single-molecule fluorescence intermittency of the main component of the PSII antenna (LHCII) under conditions that mimic efficient use of light or qE, ...

Single-molecule spectroscopy was employed to elucidate the fluorescence spectral heterogeneity and dynamics of individual, immobilized trimeric complexes of the main light-harvesting complex of plants in solution near room temperature. Rapid reversible spectral shifts between various emitting states, each of which was quasi-stable for seconds to tens of seconds, were observed for a fraction of ...

Introduction: Operations on the tympanic membrane of the middle ear, myringoplasty, and tympanoplasty are now widely accepted, and attempts are underway all over the world to standardize the surgical techniques. This study aimed to compare postoperative outcomes of endoscopic and microscopic cartilage myringoplasty in patients suffering from chronic otitis media (COM).   Mater...

    Abstract   Background: Gastroenterologists are required to obtain consent before undertaking   any endoscopic examination. Published data indicate that in practice there are many deficiencies in this process. The aim of this survey was to determine the quality of information given to patients before the endoscopic procedures in Iran .   Methods: A structured questionnaire about patient's in...
