Elucidation of the Co state with strong charge-transfer effects in charged LiCoO by resonant soft X-ray emission spectroscopy at the Co L edge.

To understand the electronic-structure change of LiCoO, a widely used cathode material in Li-ion batteries, during charge-discharge, we performed soft X-ray absorption spectroscopy (XAS) and resonant soft X-ray emission spectroscopy (RXES) of the Co L edge in combination with charge-transfer multiplet calculations. The RXES profile significantly changed for the charged state at 4.2 V Li/Li, corresponding to the oxidation reaction from a Co low-spin state for the initial state, while the XAS profile exhibited small changes.

Clinical characteristics and survival outcomes of patients with primary central nervous system lymphoma treated with high-dose methotrexate-based polychemotherapy and consolidation therapies.

Given the rarity of primary central nervous system lymphoma (PCNSL), evaluations of different high-dose methotrexate-(HD-MTX)-based treatment regimens is sparse. This retrospective, multicenter study evaluates clinical characteristics and outcomes (progression-free, overall and disease-specific survival) after five HD-MTX-based polychemotherapeutic regimens and two consolidation therapies. 346 patients with histologically confirmed PCNSL, treated with ≥ 1 cycle HD-MTX-based strategies (≥3g/m/cycle) were included.

Operando Soft X-ray Absorption of LaMn Co O Perovskites for CO Oxidation.

We employed operando soft X-ray absorption spectroscopy (XAS) to monitor the changes in the valence states and spin properties of LaMn Co O catalysts subjected to a mixture of CO and O at ambient pressure. Guided by simulations based on charge transfer multiplet theory, we quantitatively analyze the Mn and Co 2p XAS as well as the oxygen K-edge XAS spectra during the reaction process. The Mn sites are particularly sensitive to the catalytic reaction, displaying dynamics in their oxidation state.

Normal hip strength and range of motion values in youth and adult female national football teams: Data from 504 assessments.

Objectives: To determine normal hip adduction- and abduction strength and range of motion (ROM) values for youth and adult female national team football players, and evaluate if increasing age, playing position and leg dominance were associated with these strength and ROM values.

Design: Cohort study.

Setting: National football center.
