The polarizations of dielectronic recombination satellite lines for hydrogenlike F to U ions are calculated including the generalized Breit interaction(GBI). The calculated values of the asymmetry parameter are compared with other theoretical results and good agreements are obtained for all lines except for those from the level 2s2p3P1. The GBI effects on the polarization become much stronger as the atomic number increases. However, for different lines, the GBI effects on the polarization are different.

A total of 50 isolates of soil dematiaceous hyphomycetes belonging to 39 species in 18 genera were found from the area of Dahingganling Mountain Range. Among them, Monodictys arxanensis is a new species. Chrysosporium fastidium, Exserohilum pedicellatum, Monodictys asperospora, Papulaspora brachiata, Scolecobasidium anelli, Scolecobasidium verruculosum and Ulocladium tuberculatum are new to China. The other 31 taxa which have been previously reported from China are also listed.

BACKGROUND The necessity of additional gastrectomy for early gastric cancer (EGC) patients who do not meet curative criteria after endoscopic submucosal dissection (ESD) is controversial. AIM To examine the clinicopathologic characteristics of patients who underwent additional laparoscopic gastrectomy after ESD and to determine the appropriate strategy for treating those after noncurative ESD. METHODS We retrospectively studied 45 patients with EGC who underwent additional laparoscopic gastrectomy after noncurative ESD from January 2013 to January 2019 at the Cancer Hospital of the Chinese Academy of Medical Sciences. We analyzed the patients’ clinicopathological data and identified the predictors of residual cancer (RC) and lymph node metastasis (LNM). RESULTS Surgical specimens showed RC in ten (22.2%) patients and LNM in five (11.1%).Multivariate analysis revealed that positive horizontal margin [odds ratio (OR)=13.393, 95% confidence interval (CI): 1.435-125, P=0.023] and neural invasion (OR=14.714, 95%CI: 1.087-199, P=0.043) were independent risk factors for RC. Undifferentiated type was an independent risk factor for LNM (OR=12.000, 95%CI: 1.197-120, P=0.035). Tumors in all patients with LNM showed submucosal invasion more than 500 μm. Postoperative complications after additional laparoscopic gastrectomy occurred in five (11.1%) patients, and no deaths occurred among patients with complications. CONCLUSION Gastrectomy is necessary not only for patients who have a positive margin after ESD, but also for cases with neural invasion, undifferentiated type, and submucosal invasion more than 500 μm. Laparoscopic gastrectomy is a safe, minimally invasive, and feasible procedure for additional surgery after noncurative ESD. However, further studies are needed to apply these results to clinical practice.

Since the discovery of HfO2-based ferroelectric （FE） materials in 2011,considerable advancements have been made in material preparation,mechanism research,and device realization [1].Consequently,these materials are now regarded as leading candidates for embedded non-volatile memory（eNVM）.Beyond eNVM applications,recent studies have demonstrated that memory devices with antiferroelectric（AFE） films can achieve high response speeds,low latency,and reduced power consumption while maintaining excellent endurance characteristics [2,3].Additionally,the typical double hysteresis loops and multiple non-overlapping polarization current peaks of AFE films offer a novel approach to designing multistate ***,in order to further promote the application of high storage density AFE,an AFRAM electronic design automation （EDA） model must be developed,and it has yet to be proposed.

AIM To identify the clinicopathological characteristics of pT1 N0 esophageal squamous cell carcinoma(ESCC) that are associated with tumor recurrence. METHODS We reviewed 216 pT1 N0 thoracic ESCC cases who underwent esophagectomy and thoracoabdominal two-field lymphadenectomy without preoperative chemoradiotherapy. After excluding those cases with clinical follow-up recorded fewer than 3 mo and those who died within 3 mo of surgery, we included 199 cases in the current analysis. Overall survival and recurrencefree survival were assessed by the Kaplan-Meier method, and clinicopathological characteristics associated with any recurrence or distant recurrence were evaluated using univariate and multivariate Cox proportional hazards models. Early recurrence(≤ 24 mo) and correlated parameters were assessed using univariate and multivariate logistic regression *** Forty-seven(24%) patients had a recurrence at 3 to 178(median, 33) mo. The 5-year recurrence-free survival rate was 80.7%. None of 13 asymptomatic cases had a recurrence. Preoperative clinical symptoms, upper thoracic location, ulcerative or intraluminal mass macroscopic tumor type, tumor invasion depth level, basaloid histology, angiolymphatic invasion, tumor thickness, submucosal invasion thickness, diameter of the largest single tongue of invasion, and complete negative aberrant p53 expression were significantly related to tumor recurrence and/or recurrence-free survival. Upper thoracic tumor location, angiolymphatic invasion, and submucosal invasion thickness were independent predictors of tumor recurrence(Hazard ratios = 3.26, 3.42, and 2.06, P < 0.001, P < 0.001, and P = 0.002, respectively), and a nomogram for predicting recurrence-free survival with these three predictors was constructed. Upper thoracic tumor location and angiolymphatic invasion were independent predictors of distant recurrence. Upper thoracic tumor location, angiolymphatic invasion, submucosal invasion thickness, and diameter o
