Objective To explore the effect of whole-course nursing service model supported by the network platform on health awareness, quality of life and nursing outcomes of patients with ileostomy or colostomy. Methods Totally 120 patients with ileostomy or colostomy were recruited as research objects. Patients who admitted from September 2022 to February 2022 were divided in the control group (58 patients), and patients who admitted from March 2023 to August 2023 were divided into the intervention group (62 patients). The control group received routine nursing mode based on a responsibility system, and the intervention group were given the whole-course nursing service mode with the support of WeChat platform. The self-care ability, the quality of life scale scores and the occurrence of stoma complications of the two groups were compared. Results The incidence of stoma complications in the intervention group was lower than that in the control group(6. 45% vs. 12. 07%, P＞0. 05). Patients in the intervention group achieved higher scores of self-willingness, self-care ability and self-care skills compared with those in the control group three months after discharge from hospital (P＜0. 01). The total score and scores of COH-QOL-OQ including physical health, psychological health, social health and spiritual scale in the intervention group were higher than those in the control group three months after discharge from hospital (P＜0. 01). Conclusion The whole-course nursing service model supported by the network platform helps to improve the self-care ability and quality of life in patients with ileostomy or colostomy.

In this article, the notions of ∼ \sim admissible congruences and ∼ \sim normal congruences on a weakly type B semigroup are characterized and the relationship between ∼ \sim admissible congruences and ∼ \sim normal congruences is investigated. In particular, some properties of such congruences on a weakly type B semigroup are given using an approach of kernel-trace. Finally, we extend the congruence pair on an inverse semigroup to the case of a weakly type B semigroup and obtain some results.

The main aim of this article is to study admissible congruences on a type B semigroup. First, we give characterizations of the minimum admissible congruence whose trace is a normal congruence on a type B semigroup. After obtaining some properties of admissible congruences with the same trace on a type B semigroup, we introduce the notion of a normal subsemigroup and give characterizations of the minimum and maximum admissible congruences whose kernels are normal subsemigroups. Finally, the concept of a congruence pair of a type B semigroup is given, and two congruences associated with the congruence pair are obtained.

Oxidative stress is one of the important mechanisms of inner ear cell damage, which can lead to age-related hearing loss (ARHL). LncRNA H19 is significantly downregulated in the cochlea of old mouse, however, the role of H19 in the development of ARHL remains unclear. In this study, we aim to investigate the expression and function of H19 in oxidative stress injury of cochlear hair cells induced by H2O2. RT-qPCR and western blot analysis confirms that HEI-OC1 cells stimulated with H2O2 decreases the expressions of H19 and SIRT1, but increases the expression of miR-653-5p. Overexpression of H19 could increase cell viability, ATP level and mitochondrial membrane potential, but reduce mitochondrial ROS generation and cell apoptosis ratio in H2O2-stimulated HEI-OC1 cells. MiR-653-5p is a target of H19, which can bind to the 3′-UTR of SIRT1. H19 is found to regulate the expression of SIRT1 through miR-653-5p. Further experiments demonstrates that H19 regulates HEI-OC1 cell viability, ATP level, mitochondrial membrane potential, mitochondrial ROS generation, and cell apoptosis ratio via the miR-653-5p/SIRT1 axis. In conclusion, lncRNA H19 inhibits oxidative stress injury of cochlear hair cells via the miR-653-5p/SIRT1 axis.

The definition of an almost left factorizable weakly type B semigroup is introduced by using the notion of a left factorizable weakly type B monoids, and some properties and characterizations on such semigroup are obtained.

In particular, some properties of proper almost factorizable weakly type B semigroups are given.

BackgroundCompared with 2D+1D adjustment, three dimensional adjustment has a more rigorous theoretical basis. However, when the unconstrained three dimensional adjustment is applied to the observation values processing of the accelerator alignment control network, serious error accumulation will occur and resulting in obvious distortion of the results.PurposeThis study aims to expound the ways and characteristics of three dimensional adjustment error accumulation for accelerator alignment control network.MethodsFirstly, based on the layout of accelerator alignment control network and the moving station measurement method of laser tracker, the three dimensional adjustment mathematical model was analyzed, and the least-squares collocation theory was used to clearly explain the error propagation. Secondly, the characters of laser tracker measurement accuracy, station positioning and orientation accuracy and single station measurement error propagation were studied by analyzing the laser tracker 3D coordinate measurement model, measurement point error model and simulation measurement experiments. Finally, adjustment calculation of the linac control network was verified by simulation measurement, and two error accumulation suppression methods were tested.ResultsThe source and propagation mode of error accumulation are explained theoretically, and verified by simulation calculation, so are the serious error accumulation of elevation and lateral errors in three dimensional adjustment of control network in accelerator.ConclusionsProviding high-precision point coordinate constraint for three dimensional adjustment can effectively suppress error accumulation, and providing high-precision orientation constraint for station coordinate system can also achieve the effect of suppressing error accumulation.

In this paper, we develop the elementary theory of inverse semigroups to the cases of type B semigroups. The main aim of this paper is to study proper type B semigroups. We introduce first the concept of a left admissible triple. After obtaining some basic properties of left admissible triple, we give the definition of a Q-semigroup and get a structure theorem of Q-semigroup. In particular, we introduce the notion of an admissible triple and give some characterization of proper type B semigroups. It is proved that an arbitrary Q-semigroup with an admissible triple is an E-unitary type B semigroup.

Objective To establish an index evaluation system for evaluating the comprehensive clinical applications of capsule endoscopy and determine the weight of each indicator, and then utilize the evaluation system to comparatively analyze the domestic and imported capsule endoscopy in order to provide scientific basis for the applications including technology, clinic and market performance of the capsule endoscopy eventually. Methods The framework of evaluation system was preliminarily formulated through literature analysis and expert consultation, and the 3-level indicators and weight of them in capsule endoscopic evaluation were determined by Delphi method and analytic hierarchy process (AHP). Factor analysis was employed to empirically analyze the evaluation indexes of domestic and imported capsule endoscopes. Results The response rates of the 2 questionnaires were 93.3% (28/30) and 96.4% (27/28), respectively; the average authoritative coefficients of the experts were 0.867 and 0.858, respectively. The Kendall (Kendall) coordination coefficients of the 3-level indicators in the 2 questionnaires were 0.324, 0.189 and 0.140, and 0.280, 0.192 and 0.124, respectively (P < 0.01, by Chi-square test), with certain consistency. At last, we determined 3 indicators of primary indexes, 10 indicators of secondary indexes, and 41 indicators of tertiary indexes, and the weights of each indicator, among which the weights of first-level indicator for technology, clinic and market performance were 0.349 0, 0.437 4 and 0.213 6, respectively. Analysis of technical indicators showed that the domestic capsule endoscope had significantly smaller size (P < 0.01), obviously larger weight (P < 0.01), but remarkably lower resolution (P < 0.05) when compared with the imported one. In the evaluation of clinical performance indexes, the domestic capsule endoscope had significantly longer image processing time (P < 0.01), obviously lower picture resolution (P < 0.01), but markedly better portability and comfortableness of the recorder (P < 0.01) than the imported one. In terms of market performance, the price of domestic capsule endoscope was distinctly lower than that of imported capsule endoscopy (P < 0.01). Conclusion Our obtained 3-level indexes by experts are concentrated, consistent and credible. The capsule endoscopic evaluation index system constructed by Delphi and AHP is scientific, reasonable and practical. And the practical comparative analysis can further provide an objective and quantifiable basis for the research of clinical evaluations.

The aim of this paper is to study the translational hull of a strongly right type B semigroup. Our main result is to prove that the translational hull of a strongly right type B semigroup is itself a strongly right type B semigroup. As an application, we give a proof of a problem posted by Petrich on translational hulls of inverse semigroups in Petrich (Inverse Semigroups, Wiley, New York, 1984) to the cases of some strongly right type B semigroups.

On March 25th 2019, the Belle II detector recorded the first collisions delivered by the SuperKEKB accelerator. This marked the beginning of the physics run with vertex detector. The vertex detector was aligned initially with cosmic ray tracks without magnetic field simultaneously with the drift chamber. The alignment method is based on Millepede II and the General Broken Lines track model and includes also the muon system or primary vertex position alignment. To control weak modes, we employ sensitive validation tools and various track samples can be used as alignment input, from straight cosmic tracks to mass-constrained decays. With increasing luminosity and experience, the alignment is approaching the target performance, crucial for the first physics analyses in the era of Super-BFactories. We will present the software framework for the detector calibration and alignment, the results from the first physics run and the prospects in view of the experience with the first data.

The Belle II experiment features a substantial upgrade of the Belle detector and will operate at the SuperKEKB energy-asymmetric e+e− collider at KEK in Tsukuba, Japan. The accelerator completed its first phase of commissioning in 2016, and the Belle II detector saw its first electron-positron collisions in April 2018. Belle II features a newly designed silicon vertex detector based on double-sided strip layers and DEPFET pixel layers. A subset of the vertex detector was operated in 2018 to determine background conditions (Phase 2 operation). The collaboration completed full detector installation in January 2019, and the experiment started full data taking. This paper will report on the final arrangement of the silicon vertex detector part of Belle II with a focus on online monitoring of detector conditions and data quality, on the design and use of diagnostic and reference plots, and on integration with the software framework of Belle II. Data quality monitoring plots will be discussed with a focus on simulation and acquired cosmic and collision data.

Toughening polymers has attracted significant interest. Traditionally, polymer toughness is enhanced by constructing polymer networks or introducing sacrificial bonds into the chains between crosslink points. These strategies, though, introduce pronounced energy dissipation and associated heat, both of which are undesirable under long-term cyclic loading, for example at the interface of implants in the human body. By incorporating single-chain nanoparticles (SCNPs) into linear polymer chains to generate all-polymer nanocomposites (APNCs), we have been able to achieve high strength, high toughness with low energy dissipation. Using a combination of simulation and experimental results, we are advancing a “SCNPs effect” where tightly cross-linked SCNPs produce a modulus contrast to achieve strengthening and toughening. Benefitting from the soft interface, the penetrable and deformable SCNPs cause the surrounding polymer chains to move in concert, significantly reducing the interfacial friction to achieve low energy dissipation. The intramolecular cross-linking of the SCNPs and adhesion between the SCNPs and polymer matrix are critical for realizing such high-performance systems. Based on a Gaussian regression model and back propagation (BP) neural network, the mechanical strength can be predicted and is supported by simulations. The APNC concept described can be applied to elastomers and gels, broadening its utilization in high-cycle and low-dissipation applications, like soft robots, flexible sensors and cartilage replacements, and artificial heart valves.

In the paper presented the temperature of an oil-immersed transformer was measured, based on the principles of the fluorescence afterglow life. Three methods were used to calculate the fluorescence afterglow life τ by using the least squares method, the integral area ratio method and Prony algorithm. The leastsquare method, the integral area ratio method and the program of Prony algorithm are written using Matlab and C++. The Least-square fitting is susceptible to the influence of the DC component. When the DC location is different, the fluorescence afterglow life τ values vary widely. The integral area ratio method is not influenced by DC component, but it has low sensitivity. Prony algorithm is not affected by DC, it has high sensitivity. So Prony algorithm is selected as a way to obtain the fluorescence afterglow lifetime value τ.
