Association of parent-child discrepancies in educational aspirations with physical fitness, quality of life and school adaptation among adolescents: a multiple mediation model.

Background: The global public health issue of diminishing physical fitness among adolescents has gained increasing attention. The impact of parents' negative emotions or pressure regarding adolescents' educational aspirations may have a passive impact on the quality of life and adaptation of adolescents in and out of school, and ultimately harm their physical health. This study aims to explore whether parent-child discrepancies in educational aspirations influence physical fitness in adolescents through school adaptation and quality of life.

Spatial aliasing based complementary meta-gratings for the high-efficient generation of different polarized multiple beams.

We demonstrate the synthesis of split dual circularly polarized (CP) beams with an additional linearly polarized (LP) radiation simultaneously from dual superposed birefringent meta-surface lenses formed of zebra crossing shaped meta-gratings. More specifically, each of the meta-surface lens is capable of generating birefringent CP refractions with different helicities and will readily achieve triple beams of different polarizations when a couple of left-hand CP (LHCP) and right-hand CP (RHCP) lobes radiating in the same direction. Polarization states of such triple-beam radiations can be specifically defined, and the vibrating electric field of each beam would thus be prescribed to form the LHCP and RHCP waves as well as a co- /cross-LP wave.

Polarization induced reconfigurable multiple OAM vortex waves through a composite meta-surface beam former.

We demonstrate a composite meta-surface beam former to generate reconfigurable multiple orbital angular momentum (OAM) vortex waves by integrating a polarization conversion meta-mirror with a multi-functional anisotropic meta-lens. More specifically, electromagnetic fields from the feed would be firstly reflected by the meta-mirror, and then transmit through the meta-lens to form the well converged OAM vortex waves with tailored beam numbers, radiation directions and topological charges. Especially, we show that the anisotropic characteristics of the meta-lens would create different multiple OAM vortex waves when the meta-mirror is rotated or equipped with active circuits to have different polarized illuminations on the meta-lens.

Antifungal meroterpenes and dioxolanone derivatives from plant-associated endophytic fungus Phyllosticta sp. WGHL2.

Four new meroterpenes named as guignardones U-X (1-4), along with eleven known meroterpenes (5-15) and three known dioxolanone derivatives (16-18), were obtained from the endophytic fungus Phyllosticta sp. WGHL2. The structural elucidation was conducted by HRESIMS, NMR, single crystal X-ray diffraction, along with ECD calculations and comparison.

A novel fungal laccase from Sordaria macrospora k-hell: expression, characterization, and application for lignin degradation.

The laccase has the ability to oxidize substituted phenols and the water is the sole byproduct, thus it has been employed to remove and/or modify the lignin in lignocellulosic material. A putative laccase gene, LacSM, from Sordaria macrospora k-hell was screened by a genome mining approach. Then, it was cloned and highly expressed in Escherichia coli.

New Alkylitaconic Acid Derivatives from Nodulisporium sp. A21 and Their Auxin Herbicidal Activities on Weed Seeds.

Five alkylitaconic acid (AA) derivatives, including two novel compounds, epideoxysporothric acid (2) and sporochartine F (5), and three known compounds, deoxysporothric acid (1), deoxyisosporothric acid (3), and 1-undecen-2,3-dicarboxylic acid (4), were obtained from the fermentation culture of the endophytic fungus Nodulisporium sp. A21. The auxin herbicidal activities of compounds 1-4 against weed seeds were investigated under laboratory conditions.
