Use of nanomaterials (NMs) to improve plant abiotic stress tolerance (AST) is a hot topic in NM-enabled agriculture. Previous studies mainly focused on the physiological and biochemical responses plants treated with NMs under stress. To use for improving AST, it necessary understand how they act this at omics epigenetics levels.

Particularly, we experimentally demonstrate feasibility to drive DFG ZGP by all-fiber near-infrared fiber lasers consisting of 1.3 µm cw random Raman laser (RRFL) and 1.5 erbium-doped amplifier seeded distributed feedback (DFB) laser, making whole system compact robust. As result, demonstrated LWIR presents broadband spectral tuning...

Abstract The ability to combine continuously tunable narrow-band terahertz (THz) generation that can access both the far-infrared and mid-infrared regimes with nanometer-scale spatial resolution is highly promising for identifying underlying light-matter interactions realizing selective control of rotational or vibrational resonances in nanoparticles molecules. Here, we report difference frequency over 100 THz bandwidth via femtosecond optical pulse shaping. emission generated at nanoscale...

Terahertz (THz) spectroscopy is an important tool that provides resonant access to free carrier motion, molecular rotation, lattice vibrations, excitonic, spin, and other degrees of freedom. Current methods using THz radiation suffer from limits due diffraction or low-sensitivity, preventing application at the scale single nanoscale objects. Here, we present coupling between plasmonic freedom in a gold nanorod broadband emission generated proximal LaAlO3/SrTiO3 nanostructure. A strong...

In this paper, we classify all positive solutions of the critical anisotropic Sobolev equation \begin{equation*} -\Delta^{H}_{p}u = u^{p^{*}-1}, \ x\in \mathbb{R}^n \end{equation*} without finite volume constraint for $n \geq 2$ and $\frac{(n+1)}{3} \leq p < n$, where $p^{*} \frac{np}{n-p}$ denotes exponent $-\Delta^{H}_{p}=-div(H^{p-1}(\cdot)\nabla H(\cdot))$ $p$-Laplace operator. This result removes assumption on classification which was obtained by Ciraolo-Figalli-Roncoroni in literature...

유구한 역사를 가지고 있는 중국의 전통문화 중에서도 전통적인 꽃꽂이 예술은 국가무형문화유산에 등재되어 학계에서도 널리 인정받고 있다. 근래에 들어 경제와 사회의 급속한 발전에 따라 꽃꽂이에 대한 대중적 가치와 문화적 가치가 점점 향상되고 문인들의 미학은 중국 전통 예술 스타일에 깊은 영향을 미쳐서 예술에서 꽃은 창작의 매개체이며 문인의 사상과 감정, 심경을 표현하고 공감을 불러일으키고 감정을 함양하는 매개체이기도 하다. 문인 꽃구경은 자기 유흥을 위한 것일 뿐만 아니라 사회 활동의 한 형태이며 다양한 형태의 정원 가꾸기는 문인들이 꽃을 감상하고 술을 마시고 시를 짓는 주요 장소를 제공해주어 예술에 영향, 특히 영향이 상류층에 퍼졌음을 알 수 예술의 독특한 풍격은 주로 고대 미적 관념에서 비롯되며, 예술이 진정으로 자신만의 스타일을 잘 계승되려면 관념을 주도하여 더 많은 주제와 의미를 융합하고 정경교융을 담아 장기적인 발전을 촉진해야 한다.
