On Landis Conjecture for the Fractional Schr\"{o}dinger Equation
In this paper, we study a Landis-type conjecture for the general fractional
Schr\"{o}dinger equation . As a byproduct, we also proved the
additivity and boundedness of the linear operator for non-smooth
coefficents. For differentiable potentials , if a solution decays at a rate
, then the solution vanishes identically. For
non-differentiable potentials , if a solution decays at a rate
, then the solution must again be trivial. The
proof relies on delicate Carleman estimates. This study is an extension of the
work by R\"{u}land-Wang (2019).Comment: 44 page
An investigation into the design and development of a Python based data processing and graphical analysis platform
In the context of the wide application of big data, cloud computing, Internet of Things and other advanced technologies, the design
and research of data processing performance and graphical analysis platform based on Python programming language has become a new di_x005frection and new goal for the innovative research and development of data analysis platform. In order to enrich the relevant research theories
and put forward new ideas and paths for the design and development of graphical analysis platforms, this paper is based on the data processing of Python, and adopts the methods of reverse analysis and subjective assessment to explore the design and development of a new type of
graphical analysis platforms with the core of the Python web crawler technology, with a view to providing a basis for the data processing and
graphical analysis platforms to quickly analyze and process the relevant data and information and designing and developing a new graphical
analysis platform with a visualization and analysis system. Provide the basis for the design and development of a new type of data processing and graphical analysis platform with visual display performance, intuitive and efficient presentation of the pattern of change and trend of
data, to provide a reference basis for related research
The Factors That Influenced Ezra Pound’s Translation and Introduction of Chinese Culture
As a leading figure of Imagism in the early 20th century, Ezra Pound advocated guiding principles for the American New Poetry. It is quite well known that Ezra Pound was greatly influenced by Chinese culture. It is not only shown in Pound’s Cathy which consists of nineteen Chinese poems, but also proved by Pound’s introduction of Chinese Confucianism in his epic writing “Cantos”. The article aims at clarifying the factors that influenced Pound’s translation and introduction of Chinese culture in the light of aesthetics of reception and polysystem theory. The first part of the paper focuses on a brief introduction of the above theories. The second part mainly deals with the two factors exerting on Pound’s translation and introduction of Chinese culture: one is, Chinese poems represents “a new form of literature” that Pound has been seeking for a long time, that is to say, ancient Chinese poetry satisfied his expectations. The other is Ezra Pound purposed to utilize Chinese Confucian as a model for solving social problems in the chaotic, disintegrating western world
DTER: Schedule Optimal RF Energy Request and Harvest for Internet of Things
We propose a new energy harvesting strategy that uses a dedicated energy
source (ES) to optimally replenish energy for radio frequency (RF) energy
harvesting powered Internet of Things. Specifically, we develop a two-step dual
tunnel energy requesting (DTER) strategy that minimizes the energy consumption
on both the energy harvesting device and the ES. Besides the causality and
capacity constraints that are investigated in the existing approaches, DTER
also takes into account the overhead issue and the nonlinear charge
characteristics of an energy storage component to make the proposed strategy
practical. Both offline and online scenarios are considered in the second step
of DTER. To solve the nonlinear optimization problem of the offline scenario,
we convert the design of offline optimal energy requesting problem into a
classic shortest path problem and thus a global optimal solution can be
obtained through dynamic programming (DP) algorithms. The online suboptimal
transmission strategy is developed as well. Simulation study verifies that the
online strategy can achieve almost the same energy efficiency as the global
optimal solution in the long term
Leveraging Open-standard Interorganizational Information Systems for Process Adaptability and Alignment: An Empirical Analysis
PurposeThe purpose of this paper is to understand the value creation mechanisms of open-standard inter-organizational information system (OSIOS), which is a key technology to achieve Industry 4.0. Specifically, this study investigates how the internal assimilation and external diffusion of OSIOS help manufactures facilitate process adaptability and alignment in supply chain network.Design/methodology/approachA survey instrument was designed and administrated to collect data for this research. Using three-stage least squares estimation, the authors empirically tested a number of hypothesized relationships based on a sample of 308 manufacturing firms in China.FindingsThe results of the study show that OSIOS can perform as value creation mechanisms to enable process adaptability and alignment. In addition, the impact of OSIOS internal assimilation is inversely U-shaped where the positive effect on process adaptability will become negative after an extremum point is reached.Originality/valueThis study contributes to the existing literature by providing insights on how OSIOS can improve supply chain integration and thus promote the achievement of industry 4.0. By revealing a U-shaped relationship between OSIOS assimilation and process adaptability, this study fills previous research gap by advancing the understanding on the value creation mechanisms of information systems deployment
