A signed graph is acquired by attaching a sign to each edge of a simple graph, and the signed graphs have been widely used as significant computer models in the study of complex systems. The energy of a signed graph S can be described as the sum of the absolute values of its eigenvalues. In this paper, we characterize…
We experimentally demonstrate enhanced self-phase modulation in silicon nanowire waveguides integrated with layered graphene oxide films. We achieve spectral broadening of optical pulses in the GO-silicon waveguide with a broadening factor up to 2.96.
In this Research Article on page 10537, right column, there is a typographical error in the expression for the Weber number. μ should be the surface tension (γ) of the liquid. The correct formula is We=ρV2D/γ, where ρ and γ are the liquid density and surface tension, V is the droplet impact speed, and D is the droplet…
Let $\mathcal{A}$ denote the set of all analytic functions $f$ in the unit disk $\mathbb{D}:=\{z \in \mathbb{C}: |z| < 1\}$ normalized by $f (0) = 0$ and $f'(0) = 1.$ The logarithmic coefficients $γ_n$ of $f \in \mathcal{A}$ are defined by $ \log f(z)/z =2 \sum_{n=1}^{\infty}γ_{n}z^{n}.$ In the present paper, the uppe…
In a previous paper we suggested that a macroscopic force field applied across a two-dimensional electron gas channel could induce a microscopic charge density wave as soon as the proper compressibility becomes negative, which happens at densities much higher than the critical density for the Wigner crystal transition…
Nucleation—or the formation of some cluster in a medium undergoing a phase transition—is usually the initial step in a phase transition. However, this process is still not fully understood, as outstanding questions related to the role of structure, local order, and diffusion remain unanswered. Systematic supercooling…
The first quantitative measurements of the electrical resistivity in binary metallic liquids, used to probe local order in the liquid, are reported in this dissertation. The electrical resistivity is very sensitive to short and medium range ordering because the electron mean free path is approximately the same length…
This dissertation presents various surface-ligand exchange reactions on cadmium selenide quantum belts (QBs), specifically between L-type, Z-type and bound-ion-pair AX salt type ligation. The surface ligation of nanocrystals determines their optical and transport properties, and thus purposeful control of nanocrystal…
Continuous partial discharge (PD) monitoring and early PD detection is important in making sure the necessary preventative measures can be taken accordingly. This paper proposed a T-shaped partial ground microstrip patch antenna that is able to detect PD signal within the UHF range. The antenna was designed and simula…

In this paper, we consider a system of initial‐boundary value problems for parabolic equations, as a generalized version of the “φ‐η‐θmodel” of grain boundary motion, proposed by Kobayashi (2001). The system is a coupled system of an Allen–Cahn‐type equation with a given temperature source and a phase‐field model of g…
Oxygen Reduction Reaction In their Research Article on page 13778, Q. Wang et al. describe vacancy-rich Pt–Cu nanowire networks (VCu-PtCu) exhibiting superior electrocatalytic performance for the oxygen reduction reaction.
Abstract Terahertz (THz) metamaterial modulators offer multifaceted capabilities for various practical applications such as THz imaging, wireless communications, sensing, et cetera. However, compared to the modulation devices for other electromagnetic bands, the ubiquitous proliferation of THz applications is severely…
Abstract In this work, La2NiO4+δ-xCe0.55La0.45O2-δ (denoted as LNO-xLDC) with various LDC contents (x = 0, 10, 20, 30 and 40, wt %) were prepared and evaluated as bifunctional oxygen electrodes for reversible solid oxide cells (RSOCs). Compared with the pure LNO, the optimum composition of LNO-30LDC exhibited the lowe…
A rhenium-based CO2 reduction catalyst is impregnated in a polymer film deposited on colloidal imprinted carbon. The film's thickness is variable. The catalyst selectively reduces CO2 to CO with good activity and remains stable for up to 24 hours.
First update of CopyDetective: Quality analysis can now be performed using the simulation approach or the exact approach.
Nanomedicine is envisioned to have a tremendous impact on targeted drug delivery in future. Coating of nanoparticles with non-ionic surfactants has been often employed for enhancing targeting in drug delivery systems. Polysorbate 80 is one of the non-ionic surfactants used often as a coating agent for receptor-mediate…
Carbon steel pertaining to construction industry offers profuse material property is by far widely adopted but has paltry corrosion resistance in acidic environment. Corrosion is a natural oxidation reduction process, which can only be reduced but cannot be completely ruled out. Corrosion causes material loss, strengt…
Glasses and disordered materials are known to display anomalous features in the density of states, in the specific heat and in thermal transport. Nevertheless, in recent years, the question whether these properties are really anomalous (and peculiar of disordered systems) or rather more universal than previously thoug…
Abstract Hybrid organic-inorganic halide perovskites demonstrate high potential in several applications such as solar cells, field-effect transistors, light-emitting diodes and more. However, the main drawback which limits their use in such applications is their low stability in humid conditions. In this paper we impl…
