Objective To investigate the effect of induced defecation technique with deep colonic precision localization in patients with complex constipation. Methods Fifty-three patients with complex constipation who were admitted to and consulted by the Department of Rehabilitation Medicine Center from November 2021 to May 2022 were recruited as research subjects. All patients received induced defecation with deep colonic precision positioning, and intervention effect was analyzed, Results The colonic deep-precision positioning induced defecation technique was reported to significantly relieve abdominal discomfort, bloating, constipation, diarrhea, and other intestinal disorders in 53 individuals with complex constipation. After the intervention, the patients had defecation in 49 (92. 45%)cases and no defecation in 4 (7. 55%)cases; 51 (96. 23%) cases and no defecation in 2 (3. 77%)case after the intervention; abdominal symptoms improved in a total of 53 (100. 00%)cases. The Wexner constipation score of the patients after the intervention was significantly lower than that before the intervention (P＜0. 05). Conclusion On patients with difficult constipation, the approach of induced defecation with deep colonic precision positioning provided considerable therapeutic benefits and significantly alleviated their clinical symptoms.

Objective To discuss the correlation between the extraction timing of mesiodens and the orthodontic treatment duration of its eruption-related complications in children to provide a reference for the clinic. Methods The mesiodentes of 187 children were classified as eruption type (typeⅠ), dental crown impacted type (type Ⅱ), interdental impacted type (type Ⅲ), and dental root impacted type (type Ⅳ). According to the timing of extraction, mesiodentes in typeⅠ, type Ⅲ, and type Ⅳ were divided into Groups A: before the eruption of the adjacent central incisor and B: after the eruption of the adjacent central incisor. Mesiodentes in type Ⅱ were divided into Group A: before the eruption of the contralateral central incisor and B: after the eruption of the contralateral central incisor. Eruption-related complications and orthodontic treatment durations caused by mesiodens were statistically analyzed. Results There were 106 cases of displacement, 28 cases of failed eruption, 27 cases of tooth rotation, and 26 cases of individual cross-bite among the eruption-related complications caused by mesiodens. The mean orthodontic treatment cycle in Group A of type Ⅰ (7.07 ± 2.45 month), Group A of type Ⅱ (6.57 ± 1.12 month), and Group A of type Ⅲ (6.95 ± 2.52 month) were lower than that in Group B of type Ⅰ (9.67 ± 3.04 month), Group B of type Ⅱ (10.25 ± 1.29 month), and Group B of type Ⅲ (9.33 ± 3.26 month), and the differences were statistically significant (P0.05). Conclusion In most cases, the mesiodens are removed before the eruption of the adjacent central incisor, which can reduce the duration of orthodontic treatment for eruption-related complications in children.

Power to gas (P2G) technology realizes the mutual coupling of electric energy and natural gas, and plays an important role in improving the economy of multi-energy system and reducing the carbon emissions of the system. In order to solve the problem that the oxygen produced by electrolyzed water in the process of P2G conversion can not be fully utilized, A multi-energy system optimal scheduling model is proposed based on the joint operation of P2G and oxygen enriched combustion power plants. Firstly, the P2G process is divided into power to hydrogen process and methanation process. The oxygen generated in the power to hydrogen process is delivered to oxygen enriched combustion power plant for use. Then, the CO2 captured by the oxygen enriched combustion power plant and the hydrogen generated during the power to hydrogen conversion process are used as the raw materials for the methanation reaction, and the natural gas generated is supplied to the gas turbine unit for use, so as to realize the full utilization of resources. Secondly, the joint operation model of P2G and oxygen enriched combustion power plants is introduced into the multi-energy system, and a low carbon multi-energy system architecture based on the joint P2G and oxygen enriched combustion power plants is built. Finally, a low-carbon economic scheduling model with the goal of minimizing the operating cost of the multi-energy system is established and verified by setting up a scenario comparison. The simulation results show that the proposed model effectively reduces the system cost and carbon emissions.

A cornerstone of broken windows theory concerns public perceptions of disorder and crime, and the citizens' "panic response" with the onset of disorder in their neighborhoods. Naturally, assuming this dynamic to exist lends support for a significant expansion of police operations from traditional crime control to order maintenance. More specifically, the advocates of the theory presume that citizens view disorder and crime as two distinctive constructs, and further that the former triggers the latter. Broken windows theory was quite popular during the 1990s and early 2000s, a period in which order maintenance or quality of life policing reached its apex of popularity. Findings from recent studies on public perceptions of disorder and crime, however, have called into serious question: the cognitive distinction between crime and disorder. Using data collected from a random telephone survey of residents residing in the Houston metropolitan area, we follow this line of research and test the hypothesized dynamics underlying broken windows theory. Our principal findings suggest that neither a one-factor model (convergent) nor a two-factor model (discriminant) fit the empirical data when an appropriate concept validation process is carried out. Implications are drawn for broken windows theory and some specific recommendations are made for future research at the end of the study. [ABSTRACT FROM AUTHOR]

We investigate the well-posedness of the 3d co-rotational Beris-Edwards system for incompressible nematic liquid crystal flows with the Landau-De Gennes bulk potential. The system under consideration consists of the Navier–Stokes equations for the fluid velocity $ \boldsymbol u $, and an evolution equation for the $ Q $-tensor order parameter. We prove the existence of solutions to the Cauchy problem of the system with initial data $ (\boldsymbol u_0,Q_0) $ having small $ L_{uloc}^3(\mathbb{R}^3) $-norm of $ (\boldsymbol u_0,\nabla Q_0) $. Moreover, the uniqueness of $ L^3_{uloc} $-solutions is obtained. [ABSTRACT FROM AUTHOR]

The traditional von Neumann architecture of computers, constrained by the inherent separation of processing and memory units, faces challenges, for instance, memory wall issue. Neuromorphic computing and in-memory computing offer promising paradigms to overcome the limitations of additional data movement and to enhance computational efficiency. In this work, transfer-free flexible memristors based on hexagonal boron nitride films were proposed for analog neuromorphic and digital memcomputing. Analog memristors were prepared; they exhibited synaptic behaviors, including paired-pulse facilitation and long-term potentiation/depression. The resistive switching mechanism of the analog memristors were investigated through transmission electron microscopy. Digital memristors were prepared by altering the electrode materials, and they exhibited reliable device performance, including a large on/off ratio (up to 106), reproducible switching endurance (>100 cycles), non-volatile characteristic (>60 min), and effective operating under bending conditions (>100 times).
