Background: Two-dimensional (2D) transition-metal dichalcogenides (TMDCs) with intrinsically crystal inversion-symmetry breaking have shown many advanced optical properties. In particular, the valley polarization in 2D TMDCs that can be addressed optically has inspired new physical phenomena and great potential applications in valleytronics. Results: Here, we propose a TMDC-nanoantenna system t...

information seeking anxiety can be interpreted as the fear and/or apprehension of searching for information resources during the information seeking process. the current study aims to determine the prevalence and correlates of the information seeking anxiety among a group of graduate students. the target population of the study comprised 11000 postgraduate students enrolled in various graduate ...

Low-dimensional materials with topologically protected edge states have wide applications in spintronic, valleytronic, and optoelectronic nanodevices. Different from the valley-resolved quantum anomalous Hall (VQAH) state spin-polarized (VSQAH), photon-induced topological kagome-lattice nanoribbons (KLNR) can generate both valley without magnetic substrate or Rashba spin-orbit coupling (SOC). V...

Mechanical deformations in $\ensuremath{\alpha}\ensuremath{-}{\mathcal{T}}_{3}$ lattices induce local pseudomagnetic fields of opposite directionality for different valleys. When this strain is equipped with a dynamical drive, it generates complementary valley-asymmetric pseudoelectric field, which expected to accelerate electrons. We propose that by combining these effects time-dependent nonun...

Two-dimensional (2D) materials are a family of layered exhibiting rich exotic phenomena, such as valley-contrasting physics. Down to single-particle level, unraveling fundamental physics and potential applications including quantum information processing in these attracts significant research interests. To unlock great potentials, gate-controlled dot architectures have been applied 2D their het...

In this paper, we assess multidimensional QoE (Quality of Experience) of HTTP-based streaming services in seeking operation to evaluate the effect of two transmission schemes: adaptive bitrate streaming and progressive download. We perform a subjective experiment with two contents and various network load conditions. In the experiment, subjects find pre-specified scenes by means of seeking the ...

The optimization of the operation of biological reactors is an interesting non-linear problem whose solution o!ers potential economic bene"t. We apply a peak seeking method to approach the maximum biomass production rate in a continuous stirred tank bioreactor. Two models, Monod and Haldane, are investigated and it is shown by simulation that the peak seeking scheme achieves optimization for bo...

A faceted classification of interactions with information is proposed, based on an empirical study of knowledge workers in their ordinary work environments. The purpose of the classification is to inform the design of information retrieval systems which can support, within a single framework, the whole variety of interactions with information that people engage in during the course of informati...

Content-Centric Networking (CCN) employs a hierarchical but location independent content naming scheme. While such a location independent naming brings various benefits including efficient content delivery, mobility, and multihoming, location independent name prefixes are hard to aggregate. This poses a serious scaling issue on the efficiency of looking up content names in a huge Forwarding Inf...
