Penrose s ladder of more governance, more governance
Bian Yuandihan,Wang Tengfei 아시아사회과학학회 2021 Jornal of Asia Social Science Vol.4 No.3
The purpose of this paper is to explain the reasons why overload and overrun can t be cured repeatedly, which is the premise of effective overload control. At the shallow level, this is a law enforcement problem. The level of law enforcement involves many factors, such as insufficient law enforcement resources, fragmented law enforcement governance, weakening law enforcement perception, power rent-seeking and so on. Legislative level, there are some challenges whether the overly technical legislative construction can be completed by law enforcement departments. On the aspect of law-abiding, the law-abiding behavior of law-abiding people will have adverse effects on them, which is contrary to the assumption of rational people. At the deep level, there are some fundamental dynamic mechanisms in Shuangchao.This includes, but is not limited to, the inertia of overloaded culture in local society, the demand of huge infrastructure for heavy-duty transportation, the pursuit of economic efficiency by Chinese speed, and the differences between central and local economic protection.
Future prospects of mass-degenerate Higgs bosons in the CP -conserving two-Higgs-doublet model
Bian, Ligong,Chen, Ning,Su, Wei,Wu, Yongcheng,Zhang, Yu American Physical Society 2018 Physical Review D Vol.97 No.11
<P>The scenario of two mass-degenerate Higgs bosons within the general two-Higgs-doublet model (2HDM) is revisited. We focus on the global picture when two CP-even Higgs bosons of h and H are nearly mass-degenerate. A global fit to the signal strength of the 125 GeV Higgs measured at the LHC is performed. Based on the best-fit result of the 2HDM mixing angles (alpha, beta), theoretical constraints, charged and CP-odd Higgs boson direct search constraints and the electroweak precision constraints are imposed to the 2HDM parameter space. We present the signal predictions of the (4b, 2b2 gamma) channels for the benchmark models at the LHC 14 TeV runs. We also study the direct Higgs boson pair productions at the LHC, and the Z-associated Higgs boson pair production search at the ILC 500 GeV runs, as well as the indirect probes at the CEPC 250 GeV run. We find that the massdegenerate Higgs boson scenario in the Type-II 2HDM can be fully probed by these future experimental searches.</P>
A Design Method for Cascades Consisting of Circular Arc Blades with Constant Thickness
Bian, Tao,Han, Qianpeng,Bohle, Martin Korean Society for Fluid machinery 2017 International journal of fluid machinery and syste Vol.10 No.1
Many axial fans have circular arc blades with constant thickness. It is still a challenging task to calculate their performance, i.e. to predict how large their pressure rise and pressure losses are. For this task a need for cascade data exists. Therefore, the designer needs a method which works quickly for design purposes. In the present contribution a design method for such cascades consisting of circular arc blades with constant thickness is described. It is based on a singularity method which is combined with a CFD-data-based flow loss model. The flow loss model uses CFD-data to predict the total pressure losses. An interpolation method for the CFD-data are applied and described in detail. Data of measurements are used to validate the CFD-data and parameter variations are conducted. The parameter variations include the variation of the camber angle, pitch chord ratio and the Reynolds number. Additionally, flow patterns of two dimensional cascades consisting of circular arc blades with constant thickness are shown.

After implantation of a biomaterial, both the host immune system and properties of the material determine the local immune response. Through triggering or modulating the local immune response, materials can be designed towards a desired direction of promoting tissue repair or regeneration. High-throughput sequencing technologies such as single-cell RNA sequencing (scRNA-seq) emerging as a powerful tool for dissecting the immune micro-environment around biomaterials, have not been fully utilized in the field of soft tissue regeneration. In this review, we first discussed the procedures of foreign body reaction in brief. Then, we summarized the influences that physical and chemical modulation of biomaterials have on cell behaviors in the micro-environment. Finally, we discussed the application of scRNA-seq in probing the scaffold immune micro-environment and provided some reference to designing immunomodulatory biomaterials. The foreign body response consists of a series of biological reactions. Immunomodulatory materials regulate immune cell activation and polarization, mediate divergent local immune micro-environments and possess different tissue engineering functions. The manipulation of physical and chemical properties of scaffolds can modulate local immune responses, resulting in different outcomes of fibrosis or tissue regeneration. With the advancement of technology, emerging techniques such as scRNA-seq provide an unprecedented understanding of immune cell heterogeneity and plasticity in a scaffold-induced immune micro-environment at high resolution. The in-depth understanding of the interaction between scaffolds and the host immune system helps to provide clues for the design of biomaterials to optimize regeneration and promote a pro-regenerative local immune micro-environment.
