摘要:This study examines the impact of the world’s largest dam, the Three Gorges Dam (TGD), on the thermal dynamics of the Yangtze River (China). The analysis uses long-term observations of river water temperature (RWT) in four stations and reconstructs the RWT that would have oc...

摘要:Using a focused ion beam, we patterned epitaxial graphene on SiC into an array of graphene nanoribbons as narrow as 15 nm by optimizing the Ga+ ion beam current, acceleration voltage, dwell time, beam center-to-center distance and ion dose. The ion dose required to com...

摘要:Generally, there are two distinct effects in modifying the properties of low-dimensional nanostructures: surface effect (SE) due to increased surface–volume ratio and quantum size effect (QSE) due to quantum confinement in reduced dimension. The SE has been widely shown to a...

摘要:This paper contains two main contents. In the first part, we provide two counterexamples of monogamy inequalities for the squared entanglement negativity: one three-qutrit pure state which violates of the He—Vidal monogamy conjecture, and one four-qubit pure state which disp...

摘要:The emission spectra of excited radicals (OH (A2Σ), O (3p5 P), H α (3P)) and emissive species ( N2 (C3Πu)) produced by positive pulsed high-voltage needle-plane corona discharges in atmospheric N2 ...

摘要:Using first-principles calculations, we show manifestations of the quantum size effect in the dielectric function ε 2 of free-standing Al(1 1 1) ultrathin films of 1 monolayer to 20 monolayers, taking into account size dependent contributions from both interband a...

摘要:The semiconducting character of graphene and some carbon-based electrodes can lead to noticeably lower total capacitances and stored energy densities in electric double layer (EDL) capacitors. This paper discusses the chemical and electronic structure modifications that enha...

摘要:Using first-principles density functional theory (DFT) hybrid functional calculations, we demonstrate the formation of a quantum spin Hall (QSH) state on a Ge(111) surface. We show that a 1/3 monolayer (ML) Cl-covered Ge(111) surface offers an ideal template for metal, such ...

摘要:Proton emission from solid foil targets irradiated by relativistically intense femtosecond laser pulses is studied experimentally. Broad plateaus in energy spectra are measured from micron-thick targets when the incident laser pulses have relatively low intensity contrasts. It is...

摘要:We report a modeling study of tumor response after stereotactic body radiation therapy (SBRT) for early-stage non-small-cell lung carcinoma using published clinical data with a regrowth model. A linear-quadratic inspired regrowth model was proposed to analyze the tumor contr...
