Reduced ascorbate pool and its maintenance are important determinants of O damage to net photosynthetic rate in Fagus crenata under elevated CO and soil N supply.

Many studies have reported modification in the degree of O damage to photosynthesis by elevated CO and soil N supply. However, the mechanism underlying the modification is unclear. To clarify the important determinants in the degree of O damage to net photosynthetic rate (A) in the leaves of Fagus crenata (Siebold's beech) under elevated CO and with different soil N supply, F.

Degradation of autotoxic chemicals and maintainence of electrical conductivity recover growth, yield and nutrient absorption of successive lettuce in recycled hydroponics.

In recycled hydroponics, successive crop cultivation by maintaining electrical conductivity (EC) suffers lower growth performance due to accumulating autotoxic root exudates. In this study, the efficiency of alternate current electro degradation (AC-ED) was evaluated for degrading allelochemicals and recovering retarded lettuce yield cultivated in EC-adjusted repeatedly used nutrient solutions. From benzoic acid (BA)-added nutrient solution, BA was completely degraded after 24 h by applying AC-ED at 551 and 940 Hz frequency with 50 and 80% electrical duty.

The onset of cerebral infarction may be affected by differences in atmospheric pressure distribution patterns.

Background: Some papers have highlighted a possible causal relationship between the onset of ischemic stroke and weather conditions. This study aimed to elucidate the onset mechanism of cerebral infarction from a meteorological approach. We focused on the atmospheric pressure distribution patterns (APDPs).

Extremely large lamb shift in a deep-strongly coupled circuit QED system with a multimode resonator.

We report experimental and theoretical results on the extremely large Lamb shift in a multimode circuit quantum electrodynamics (QED) system in the deep-strong coupling (DSC) regime, where the qubit-resonator coupling strength is comparable to or larger than the qubit and resonator frequencies. The system comprises a superconducting flux qubit (FQ) and a quarter-wavelength coplanar waveguide resonator ([Formula: see text] CPWR) that are coupled inductively through a shared edge that contains a Josephson junction to achieve the DSC regime. Spectroscopy is performed around the frequency of the fundamental mode of the CPWR, and the spectrum is fitted by the single-mode quantum Rabi Hamiltonian to obtain the system parameters.
