During the COVID-19 pandemic, older consumers have increased their usage of social networking services (SNSs) to avoid isolation, yet this behavior remains unexplored. Through selective optimization with compensation theory, authors combine concepts from gerontology and marketing investigate following research question: How does consumers’ SNSs during pandemic interrelate constructs well-being? The draws on qualitative data collated lockdown in United Kingdom, including 14 semistructured...
Fishnet metamaterials have shown their excellent absorption at terahertz and optical frequencies. Here, we experimentally demonstrate an ultra-broadband lightweight microwave absorber by fabricating a conventional magnetic absorbing material into fishnet-like structure. Compared with the pure material, broadest bandwidth (less than −10 dB) of is extended from 7.4–11 GHz to 4.8–20.7 GHz. Meanwhile, high surface density, which important shortcoming for materials, has been reduced clearly...
Composite microspheres with carbonyl iron cores and graphite shells are prepared by a mechanical ball milling method. The microwave absorption properties of these investigated in terms complex permittivity permeability, impedance matching property, reflection loss. morphology conductivity the can be well tuned controlling time to achieve improvement its characteristics. In addition, integration composition unique structure, iron/graphite possess better than graphite. show highly strong...
Abstract In this paper, the resonant nonlinear Schrödinger equation with time-dependent coefficients which appears in research process of Madelung fluid is probed by means two different methods. As an outcome, dozens distinct types complex exact solutions are built condition taking dual-power law nonlinearity into account. More specifically, a range solitary, soliton as well elliptic wave offered terms unified method, and series hyperbolic, triangular, Jacobi doubly periodic, rational...
Systems of spins with strong dipolar interactions and controlled dimensionality enable new explorations in quantum sensing simulation. In this work, we investigate the creation a two-dimensional ensemble nitrogen-vacancy (NV) centers generated via plasma-enhanced chemical vapor deposition on (111)-oriented diamond substrates. We find that growth (111) plane yields high incorporation spins, both nitrogen NV centers, where density latter is tunable miscut substrate. Our process allows us to...
Systems of spins engineered with tunable density and reduced dimensionality enable a number advancements in quantum sensing simulation. Defects diamond, such as nitrogen-vacancy (NV) centers substitutional nitrogen (P1 centers), are particularly promising solid-state platforms to explore. However, the ability controllably create coherent, two-dimensional spin systems characterize their properties, density, depth confinement, coherence is an outstanding materials challenge. We present refined...
We investigate the thermal diffusion behavior of aqueous solutions nucleotides using an infrared forced Rayleigh scattering (IR-TDFRS) setup. In this work we study 5 nucleotides: cyclic adenosine and guanosine monophosphate, 5'-adenosine 5'-cytidine also diphosphate in water. The structures vary systematically, which results different physical properties such as acidity, solubility, hydrophobicity, melting point. discuss connection between nucleotides. Additionally, case alkanes...
In this paper, we introduce Watch-And-Help (WAH), a challenge for testing social intelligence in agents. WAH, an AI agent needs to help human-like perform complex household task efficiently. To succeed, the i) understand underlying goal of by watching single demonstration performing same (social perception), and ii) coordinate with solve unseen environment as fast possible (human-AI collaboration). For challenge, build VirtualHome-Social, multi-agent environment, provide benchmark including...
Moiré superlattices in van der Waals (vdW) heterostructures form by stacking atomically thin layers on top of one another with a twist angle or lattice mismatch. The resulting moiré potential leads to strong modification the band structure, which can give rise exotic quantum phenomena ranging from correlated insulators and superconductors excitons Wigner crystals. Here, we demonstrate dynamic tuning WSe2/WS2 heterostructure at cryogenic temperature. We utilize optical fiber tip scanning...
Spin squeezing is a form of entanglement that reshapes the quantum projection noise to improve measurement precision. Here, we provide numerical and analytic evidence for following conjecture: any Hamiltonian exhibiting finite temperature, easy-plane ferromagnetism can be used generate scalable spin squeezing, thereby enabling quantum-enhanced sensing. Our conjecture guided by connection between Fisher information pure states spontaneous breaking continuous symmetry. We demonstrate...
Human-caused nitrogen (N) deposition is a global environmental issue that can change community composition, functions, and ecosystem services. N affects plants, soil, microorganisms regionally linked to ecosystem, climate factors. We examined the effects of six addition levels (0, 2.34 g, 4.67, 9.34,18.68, 37.35 g m−2 yr−1) on aboveground vegetation, surface soil properties, microbial community. Alterations in communities response were monitored using 16S rRNA (16S ribosomal ribonucleic...
