    We study the TTˉT\bar T deformation on a multi-quantum mechanical systems. By introducing the dynamical coordinate transformation, we obtain the deformed theory as well as the solution. We further study the thermo-field-double state under the TTˉT\bar T deformation on these systems, including conformal quantum mechanical system, the Sachdev-Ye-Kitaev model, and the model satisfying Eigenstate Thermalization Hypothesis. We find common regenesis phenomena where the signal injected into one local system can regenerate from the other local system. From the bulk picture, we study the deformation on Jackiw-Teitelboim gravity governed by Schwarzian action and find that the regenesis phenomena here are not related to the causal structure of semi-classical wormhole.Comment: 20 pages, 5 figure

    Development of a trench cutting re-mixing deep wall method model test device

    The trench cutting re-mixing deep wall (TRD) is a new type of underground waterproof curtain. Mixing uniformity is the key index affecting the efficiency and quality of this method. However, because of many influencing factors, existing theories cannot be used to express the relationship between various factors and mixing uniformity. By analyzing the cutting and mixing process of the TRD method, the main factors affecting the uniformity of the mixing were obtained. A model test device was designed and manufactured, based on Buckingham's pi theorem. The validity of the model test device was verified through a comparative analysis of model and field test results. The model test device was demonstrated to be able to simulate the mixing process of the TRD method. The results provide guidance for promotion and better application of the TRD method

    The Relationship Between Political Skill And Employee Voice Behavior From An Impression Management Perspective

    This research focused on the self-serving motivation of voice behavior from an impression management perspective, different from the previous studies on the altruistic motivation. The purpose of this study was to construct a multilevel theoretical model that proposed how political skill operates to exercise effects on employee voice behavior in the context of organizational politics climate from an impression management perspective. We hypothesized the positive relationship between political skill and employee voice behavior, and the mediating role of impression-management motives, and then examined the cross-level effects of organizational politics climate on the individual-level employee voice phenomenon. An evaluation of research limitations, suggestions for future research, contributions to the literature and practical implications were discussed finally

    Method to Select Target Wells and Target Zones for the Technique of Water Plugging

    Water shutoff is an effective way to enhance oil recovery and lower water production. It is crucial to select target wells and target zones properly, otherwise, the effect of water shutoff may be disturbed. Traditionally, the job to select target wells and target zones is always done artificially and imprecisely, as a result, water shutoff does not perform as good as it can. This paper proposes a fuzzy method capable of optimizing the selection of target wells and target zones for water shutoff. This study plays a significant role in the technique of water shutoff
