    Abstract The k_means clustering algorithm has very extensive application. The paper gives out_in clustering algorithm based on density. The algorithm combines distance with data density to adapt to data distribution. It can effectively solve the clustering of data. Out_in clustering based on density reduce distorition by move out and move in. Simulation results show that out_in clustering algorithm is more effective than the k_means clustering algorithm.

    Abstract This article designs a new hierarchical distributed data-driven adaptive learning control algorithm to accomplish the leader-following tracking control objective for nonaffine nonlinear multiagent systems (MASs). The proposed hierarchical control structure is composed of a distributed observer and a decentralized data-driven adaptive learning controller. Considering that some followers cannot directly receive information from the leader, a distributed observer is designed to estimate the information of the leader. Based on this, a decentralized data-driven adaptive learning controller is further devised to enable the follower to track the estimated information of the leader, where the model parameter learning algorithm is developed to capture the dynamic characteristics of the original system. One advantage of the developed hierarchical control learning algorithm is that neither the leader's system model nor the follower's system model is needed. The other one is the elimination of the noncausal problem without the additional assumption. Simulation results exemplify the merits of the theoretical results by comparisons.

    Abstract BACKGROUND In the treatment of pes planus, if the implant does not match the anatomical structures of the sinus tarsi, synovitis can develop, causing pain symptoms. In the interest of making clinical recommendations for extra-osseous talotarsal stabilization, the goal of the present study was to characterize the anatomical characteristics of the sinus tarsi in patients with pes planus using magnetic resonance imaging (MRI) scans. MATERIAL AND METHODS This was a retrospective study involving 56 pes planus patients and 56 healthy volunteers from January 2014 to May 2022. The sinus tarsi was measured for length and width, for angle with the coronal and sagittal axes, and for length of the subtalar implant. RESULTS All examined metrics showed a difference between pes planus patients and healthy participants, with the exception of the subtalar implant's length. The average sinus tarsi length and width among pes planus patients were 19.23 mm and 2.91 mm, respectively. The angle between the sinus tarsi and the coronal and sagittal axes was 21.418° and 25.077°, while the length of approach was 33.06 mm and 0.76°. The only gender differences that were statistically significant were in the length and width of the sinus tarsi. There were no notable variations between the left and right sides. CONCLUSIONS Sinus tarsi morphology may be impacted by pes planus. When treating patients with pes planus, clinicians should take these anatomical factors into consideration since they might more completely characterize the anatomical features of the sinus tarsi.

    Abstract As a powerful tool, polymerase chain reaction (PCR) has been indispensable and widely used in a large array of applications. In practice, many factors may affect the overall performance of a PCR. One such factor is the stability of intramolecular secondary structure formed within single-stranded template. The higher the stability of such a structure, the more likely it will have adverse effects on PCR performance. Traditionally, chemical reagents believed to reduce the stability of nucleic acid secondary structures, such as DMSO and betaine, have been used to mitigate their adverse effects on PCR performance. However, these reagents have apparent downsides including increasing replication error rate, inhibiting polymerase activity, and being ineffective against secondary structures of very high stabilities. Disruptors, a new class of oligonucleotide reagents, do not exhibit such downsides. They are specifically designed to target intramolecular secondary structures only without any effect on the replication of other regions of the template. Their effective concentration range for improving PCR performance is well tolerated by PCR. And they are very effective in improving PCR performance on templates that are notoriously difficult to amplify by PCR even in the presence of DMSO or betaine, e.g., the inverted terminal repeat of adeno-associated virus (AAV-ITR). In this chapter, the application of disruptors in PCR is described with AAV-ITR as the example template.

    Abstract The America's Poison Centres National Poison Data System (NPDS) is set up for the active surveillance of voluntarily reported poisoning cases in near real-time. The Centres for Disease Control and Prevention (CDC)'s Wide-ranging Online Data for Epidemiologic Research (WONDER) database is final national mortality data from state registries. We compared suicide poisoning deaths in both datasets from 2000 to 2020 and tested their relationship using a simple linear regression model. Mean annual suicide poisoning deaths during the review period were 699 (SD 145) in NPDS, and 6150 (SD 577) in WONDER. NPDS annual cases averaged 11% of cases recorded in WONDER (SD 2%; Range 8%-16%). The regression coefficient for the linear relationship between annual deaths recorded in both datasets was 0.18 (p-value<0.001, R

    Abstract This study used the consistency-constrained double-difference tomography method to invert 3D fine structure models of Vp, Vs, Vp/Vs at depths above 60 km, and precise relocation parameters of earthquakes in the Bohai Sea. According to the results, the velocity structures of P-wave and S-wave in the Bohai Sea area were highly similar and demonstrated noticeable lateral non-uniformity. The crust beneath the Tanlu Fault displayed a clear stratification structure, with a continuous velocity transition in the middle of the crust. The intricate crustal structure beneath the Zhangpeng Fault displayed high-velocity bodies in the crust and low-velocity anomalous zones connected to the top of the mantle in the lower section of the crust. The structural pattern in the deep crust of the Bohai Sea controls the occurrence characteristics of the Zhangpeng Fault and the Tanlu Fault. The earthquakes in the Bohai Sea area were concentrated mainly in the southern part near the Zhangpeng Fault. There is a good correspondence between the relocated earthquakes and velocity structure. There are many significant differences in crustal structure between the north and south of the Bohai Strait, and there are obvious velocity anomalies in the middle and upper crust. The distribution shape of high Vp/Vs value indicates that mantle material migration has occurred at the bottom of the crust. This paper provided important reference for further research on the relationship between deep tectonic features and tectonic activity in the North China Craton.

    Abstract lncRNA TPT1-AS1 plays an oncogenic role in ovarian and cervical cancers. However, its involvement in the pathological progress of esophageal squamous-cell carcinomas (ESCCs) is unclear. lncRNA TPT1-AS1 was mainly localized in the cytoplasm of ESCC cells and interacted with miR-26a. In ESCC tissues, lncRNA TPT1-AS1 level was obviously increased, while miR-26a level was decreased. Interestingly, lncRNA TPT1-AS1 level was not significantly correlated with miR-26a level but was positively correlated with HMGA1 mRNA, a target of miR-26a. In ESCC cell lines KYSE510 and KYSE-30, lncRNA TPT1-AS1 overexpression enhanced HMGA1 expression, while it had no effect on miR-26a expression. Cell migration and proliferation assays indicated that lncRNA TPT1-AS1 and HMGA1 overexpression promoted ESCC cell migration and invasion, while their effects were alleviated by miR-26a overexpression. The migration and invasion of ESCC cells were suppressed by lncRNA TPT1-AS1 knockdown. In conclusion, lncRNA TPT1-AS1 plays an oncogenic role in ESCC and might function by upregulating HMGA1 via sponging miR-26a.

    Abstract Objective To evaluate the use of dental operating microscope in treating calcified canals. Methods 369 calcified canals were treated with C⁃Pilot files and ethylene diamine tetraacetic acid (EDTA) under dental operating microscope. The canals were grouped based on the calcified teeth site and calcified location in canals, and then the suc⁃ cess rates of negotiating were analyzed with c2 test. Results 310 of 369 calcified canals were negotiated under dental operating microscope, the negotiating rate was 84.01%. For the anterior, premolar and molar, the negotiating rate were 94.78%, 85.98%, and 74.15% respectively. There were significant differences between anterior and molar teeth (c2 = 19.658, P＜0.05). When the calcification was located in straight canals or above the root canal curvature, canals were negotiated with a success rate of 96.85%. However, it decreased to 39.76% when the calcified portion located below the root canal curvature (c2 = 156.113, P＜0.05). Conclusion It is an effective way to use dental operating microscope and C⁃Pilot files to treat calcified canals, but the therapeutic effects might be affected by sites of the teeth and the calci⁃ fied location in canals.
