Oxygen Vacancy and Interface Effect Adjusted Hollow Dodecahedrons for Efficient Oxygen Evolution Reaction.

Metal-organic frameworks (MOFs) with special morphologies provide the geometric morphology and composition basis for the construction of platforms with excellent catalytic activity. In this work, cobalt-cerium composite oxide hollow dodecahedrons (Co/Cex-COHDs) with controllable morphology and tunable composition are successfully prepared via a high-temperature pyrolysis strategy using Co/Ce-MOFs as self-sacrificial templates. The construction of the hollow structure can expose a larger surface area to provide abundant active sites and pores to facilitate the diffusion of substances.

[Formula: see text]-Improved nonparallel support vector machine.

In this paper, a [Formula: see text]-improved nonparallel support vector machine ([Formula: see text]-IMNPSVM) is proposed to solve binary classification problems. In this model, we use related ideas of [Formula: see text]-support vector machine([Formula: see text]-SVM), the parameter [Formula: see text] is introduced to control the limits of the support vectors percentage. In the objective function, the parameter [Formula: see text] is increased to ensure that [Formula: see text]-band is kept as small as possible.

[Clinical study on female obesity complicated with climacteric syndrome treated by acupuncture].

Objective: To explore the mechanism of acupuncture in treating obesity complicated with climacteric syndrome (OCCS).

Methods: Thirty female OCCS patients were treated by acupuncture, combination of body and auricular acupuncture, according to the treating principle based on syndrome differentiation. The changes in symptoms, signs, obesity index, Kupperman index, vegetative nerve system equilibrium index (Y value), levels of estradiol (E2), luteinizing hormone (LH), follicle stimulating hormone (FSH), gonadotropin releasing hormone (GnRH), leptin (LP), insulin (INS), nitric oxide (NO), nitric oxide synthase (NOS) and insulin activation index (IAI) in patients were observed.
