Optimal bounds for Neuman-Sándor mean in terms of the convex combination of the logarithmic and the second Seiffert means

In the article, we prove that the double inequality α L ( a , b ) + ( 1 − α ) T ( a , b ) 0 $a,b>0$ with a ≠ b $a\ne b $ if and only if α ≥ 1 / 4 $\alpha\ge1/4$ and β ≤ 1 − π / [ 4 log ( 1 + 2 ) ] $\beta\le1-\pi/[4\log(1+\sqrt{2})]$ , where NS ( a , b ) $\mathit{NS}(a,b)$ , L ( a , b ) $L(a,b)$ and T ( a , b ) $T(a,b)$ denote the Neuman-Sándor, logarithmic and second Seiffert means ...

The Coupling Effects of Surface Plasmon Polaritons and Magnetic Dipole Resonances in Metamaterials

We numerically investigate the coupling effects of surface plasmon polaritons (SPPs) and magnetic dipole (MD) resonances in metamaterials, which are composed of an Ag nanodisk array and a SiO2 spacer on an Ag substrate. The periodicity of the Ag nanodisk array leads to the excitation of SPPs at the surface of the Ag substrate. The near-field plasmon interactions between individual ...

明代 "古詩

近年來,明清時期“古詩”總集的編撰與出版逐漸得到學界注意。多數研究以出版業的興起爲時代背景,檢析一部或幾部重要選本的内容及其所體現的文學觀點。這些考證及研究則爲本文的分析提供了可能與基礎。本文嘗試另闢蹊徑,以副文本(paratext)的閲讀爲中心,兼及文本,從宏觀層面勾勒有明一代“古詩”總集的編撰與出版,以及這類書籍可能的流通與接受之宏觀趨勢。第一部分以筆者檢索書目所累計的條目爲基礎,對先唐詩文集在明代的編纂出版進行量化分析,從而進一步確認明代是先唐詩文集產生的高峰;随後三個部分各以不同的 副文本(paratext)要素爲討論中心:首先,以書名爲中心,對書名加以分組語義詞頻考察,探尋先唐詩類總集的命名策略與所呈現的編纂趨勢;其次,以序言爲中心,管窥總集編纂動機的變化; ...

Preparation and Enhanced Catalytic Hydrogenation Activity of Sb/Palygorskite (PAL) Nanoparticles

A Sb/palygorskite (PAL) composite was synthesized by a facile solvothermal process and applied in catalytic hydrogenation of p-nitrophenol for the first time. It was found that the Sb nanoparticles with the sizes of 2–5 nm were well dispersed on the fiber of PAL, while partial aggregated Sb nanoparticles with sizes smaller than 200 nm were also loaded on the PAL. The Sb/PAL ...

Upregulation of DARS2 by HBV promotes hepatocarcinogenesis through the miR-30e-5p/MAPK/NFAT5 pathway

Infection with the hepatitis B virus (HBV) is closely associated with the development of hepatocellular carcinoma (HCC). The osmoregulatory transcription factor nuclear factor of activated T-cells 5 (NFAT5) has been shown to play an important role in the development of many types of human cancers. The role of NFAT5 in HBV-associated HCC has never previously been investigated. We ...

Systematic engineering of pentose phosphate pathway improves Escherichia coli succinate production

Background Succinate biosynthesis of Escherichia coli is reducing equivalent-dependent and the EMP pathway serves as the primary reducing equivalent source under anaerobic condition. Compared with EMP, pentose phosphate pathway (PPP) is reducing equivalent-conserving but suffers from low efficacy. In this study, the ribosome binding site library and modified multivariate modular ...

TAGLN2 is a candidate prognostic biomarker promoting tumorigenesis in human gliomas

Transgelin-2 (TAGLN2) is a member of the calponin family of actin-bundling proteins that is involved in the regulation of cell morphology, motility, and cell transformation. Here, the clinical significance and potential function of TAGLN2 in malignant gliomas were investigated. Molecular and clinical data was obtained from The Cancer Genome Atlas (TCGA) database. Gene ontology and ...

Effects of Laparoscopic Roux-en-Y Gastric Bypass for Type 2 Diabetes Mellitus: Comparison of BMI > 30 and < 30 kg/m2

Background Recently, many studies focused on type 2 diabetes mellitus (T2DM) patients with body mass index (BMI) 30 kg/m2. Methodology Seventy patients with uncontrolled T2DM underwent laparoscopic RYGB from May 2010 to December 2015 in the GI Department of Daping Hospital. Weight, BMI, waist circumference, glucose, and lipid metabolic parameters were collected and evaluated at ...

Engineering the Complex-Valued Constitutive Parameters of Metamaterials for Perfect Absorption

We theoretically studied how to directly engineer the constitutive parameters of metamaterials for perfect absorbers of electromagnetic waves. As an example, we numerically investigated the necessary refractive index n and extinction coefficient k and the relative permittivity ε and permeability μ of a metamaterial anti-reflection layer, which could cancel the reflection from a ...
