Characterizing nonequilibrium dynamics in quantum many-body systems is a challenging frontier of physics. In this Letter, we systematically construct solvable nonintegrable quantum circuits that exhibit exact hidden Markovian subsystem dynamics. This feature thus enables accurately calculating local observables for arbitrary evolution time.

However, many of current methods for synthesizing NiCoO/NiCo-LDH suffer from long synthesis times, complex preparation process, and high temperatures and high pressures. In this study, we present a green, simple, and efficient approach known as assisted liquid-phase plasma electrolysis, which realizes the rapid fabrication of ultra-fine NiCoO/NiCo-LDH nanoparticle-decorated electrospun carbon nanofibers (NiCoO/NiCo-LDH/CNFs) composites.

The lithium (Li)-air battery has an ultrahigh theoretical specific energy, however, even in pure oxygen (O ), the vulnerability of conventional organic electrolytes and carbon cathodes towards reaction intermediates, especially O , and corrosive oxidation and crack/pulverization of Li metal anode lead to poor cycling stability of the Li-air battery. Even worse, the water and/or CO in air bring parasitic reactions and safety issues. Therefore, applying such systems in open-air environment is challenging.

We report a case of moyamoya disease in a 3-year-old Chinese girl with partly reversible white matter lesions. This case indicates that, in pediatric moyamoya disease, white matter lesions may be associated with cerebral ischemia, and they may be reversible after treatment.

Quantum chemical calculations were conducted under the framework of density functional theory (DFT) at M06-2x/6-311+(d, p) level of theory to predict the possible mechanism as well as the new absorption bands. New bands whose intensity increased with annealing, were observed in twin jet deposition, which indicated the formation of primary ozonides, CI and secondary ozonides in the investigated systems.

The aim of this pilot study was to assess the predictive value of red blood cell lifespan (RBCLS), as determined by an automated CO breath test analysis approach, in the differential diagnosis of these two common forms of microcytic hypochromic anemia (MHA).
Methods: RBCLS measurements were conducted in 35 healthy controls (HCs) and 114 patients diagnosed with MHA (IDA, N = 59; and Thal, N = 55) with ELS TESTER that provides a direct RBCLS value read-out.

Since the American Medical Association published the 2011 guidelines for immune thrombocytopenia, China has been the first to update the guidelines for immune thrombocytopenia based on evidence-based medicine. Recently, there have been many breakthroughs in clinical research published, especially the Chinese medical workers have made a prominent contribution to the treatment of the immune thrombocytopenia. However, the references of systematic drug introduction for children, adults, aged and pregnant women are still insufficient, and the first or second line treatment for some patients were ineffective.
