The near-unity efficiency of energy transfer in photosynthesis makes photosynthetic light-harvesting complexes a promising avenue for developing new renewable energy technologies. Knowledge of the energy landscape of these complexes is essential in understanding their function, but its experimental determination has proven elusive. Here, the observation of quantum coherence using two-dimensiona...

INTRODUCTION Anatomical abnormalities in the lower limb vessels are uncommon. However, the preoperative evaluation of the anatomical variations is very important for planning the operation procedure to prevent jeopardizing the donor leg. CASE PRESENTATION In this case report, a 23-year-old Asian woman who was scheduled to have vascularized free fibula transplantation for reconstruction of her...

Accurate knowledge of Balise dynamic performance is essential for train position perception and safe operation. For the in high-speed railway, whose under energy harvesting affected by operation environmental uncertainty, such even more critical. This study proposes a new analyse method, which analyses input quantitatively expressing uncertainty. The complete electrical model consisted radio fr...

The object of this study was evaluation of a walking tractor drawn peanut harvester at different conditions of soil moisture content and forward speed and comparing it with manual harvesting. The evaluation factors for peanut harvester were two levels of soil moisture content and three levels of forward speed. The results revealed that the effect of soil moisture content was only significant on...

Automation in cherry harvesting is essential to reduce the demand for seasonal labor for cherry picking and reduce the cost of production. The mechanical shaking of tree branches is one of the widely studied and used techniques for harvesting small tree fruit crops like cherries. To automate the branch shaking operation, different methods of detecting branches and cherries in full foliage canop...

Exciton harvesting is of fundamental importance for the efficient operation of organic photovoltaic devices. The quantum efficiencies of many organic and hybrid organicinorganic devices are still limited by low exciton harvesting efficiencies. This problem is most apparent in planar heterostructures that suffer from a direct tradeoff between light absorption and exciton harvesting. One approach...

BACKGROUND The use of the radial artery (RA) in coronary bypass operations has become increasingly popular in recent years, but there is almost no documentation regarding the midterm and long-term arm complications. METHODS Between January 1 and December 31, 1998, 109 patients underwent operations for myocardial revascularization employing a pedicled RA as 1 of the coronary grafts. The patien...

The lutein-5,6-epoxide (Lx) cycle operates in some plants between lutein (L) and its monoepoxide, Lx. Whereas recent studies have established the photoprotective roles of the analogous violaxanthin cycle, physiological functions of the Lx cycle are still unknown. In this article, we investigated the operation of the Lx cycle in light-harvesting antenna complexes (Lhcs) of Inga sapindoides Willd...
