Observation of Three Resonant Structures in the Cross Section of e^{+}e^{-}→π^{+}π^{-}h_{c}.

Using e^{+}e^{-} collision data collected with the BESIII detector operating at the Beijing electron positron collider, the cross section of e^{+}e^{-}→π^{+}π^{-}h_{c} is measured at 59 points with center-of-mass energy sqrt[s] ranging from 4.009 to 4.950 GeV with a total integrated luminosity of 22.

Two-dimensional 1T-phase MnIrO for high-performance acidic oxygen evolution reaction.

Proton exchange membrane water electrolysis (PEMWE) is regarded as the most promising technique for the sustainable production of green hydrogen due to its multiple advantages such as high working current density and high hydrogen purity. However, the anodic oxygen evolution reaction (OER) has a significant impact on the overall efficiency of the electrolytic water reaction due to its sluggish kinetics, which has prompted the search for catalysts possessing both high activity and durability. Iridium oxide exhibits excellent stability under acidic conditions but has poor catalytic activity, leading to its inability to meet the strict requirements of large-scale industrial applications.

An international prognostic index to predict the early chemoimmunotherapy failure of diffuse large B-cell lymphoma.

 Approximately 30-40% of diffuse large B-cell lymphoma (DLBCL) patients will develop relapse/refractory disease, who may benefit from novel therapies, such as CAR-T cell therapy. Thus, accurate identification of individuals at high risk of early chemoimmunotherapy failure (ECF) is crucial. Methods.
