The presence of small islands and reefs,which are too small to be resolved within a computational grid,is a notable source of error in wave modeling.This study presents an approach that considers subgrid obstacles within the complicated characteristic inlaid scheme(CCIS),a wave propagation algorithm adopted by the WAve Model developed by the Key Laboratory of MArine Science and NUmerical Modeling(MASNUM-WAM)of the Ministry of Natural Resources(People's Republic of China).While the CCIS can solve for wave energy flux with strong physical meaning,neither of the existing subgrid obstruction algorithms(i.e.,GRIDGEN and UOST)can be directly applied within it.To develop this new approach,the transparency rate,estimated using the opensource software alphaBetaLab,is incorporated into the CCIS interpolation procedure.Additionally,a scaling factor is introduced to adjust the rate coefficient for various computational resolutions.Numerical tests,which included the Ryukyu Islands and the Batan and Babuyan Islands,revealed that the deviation in simulated significant wave height(SWH)between coarse and fine grids could be reduced from>0.5 to<0.2 m,with a background SWH of 4 m.Moreover,the mean absolute SWH error was reduced by 40%-70%.These results indicate that the newly proposed subgrid obstruction scheme effectively represents the effects of unresolved obstacles within the CCIS framework used by MASNUM-WAM. 展开更多

Objective:To explore the application effect of combined exercise intervention based on the hospital-community-family model on intrinsic capacity in elderly patients with diabetes mellitus complicated by chronic kidney disease.Methods:Using convenience sampling,100 elderly patients with diabetes mellitus complicated by chronic kidney disease who received treatment in the endocrinology department of a tertiary A-level hospital from May 2024 to May 2025 were selected as the study subjects.They were randomly divided into an experimental group(50 cases)and a control group(50 cases)using a random number table method.The control group received routine health education and telephone follow-up,while the experimental group,in addition to the control group’s interventions,underwent combined exercise intervention based on the hospital-community-family model.Remote medical guidance was utilized to monitor and study the application effect of exercise intervention on intrinsic capacity in elderly patients with diabetes mellitus complicated by chronic kidney disease.Fasting blood glucose,2-hour postprandial blood glucose,glomerular filtration rate,6-minute walk distance,and scores in five dimensions of intrinsic capacity(exercise,cognition,psychology,vitality,and sensation)were measured before the intervention,at 4 weeks of intervention,and at 12 weeks of intervention for both groups.Results:Before the exercise intervention,there were no statistically significant differences(p>0.05)between the two groups in terms of fasting blood glucose,2-hour postprandial blood glucose,glomerular filtration rate,6-minute walk distance,and scores across five dimensions of intrinsic capacity:mobility,cognition,psychology,vitality,and sensation.After 12 weeks of intervention,the experimental group demonstrated significantly higher scores than the control group in glomerular filtration rate,6-minute walk distance,and the dimensions of mobility,cognition,and vitality within intrinsic capacity,with all differences being statistically significant(p<0.05).Conversely,the experimental group showed significantly lower scores than the control group in fasting blood glucose,2-hour postprandial blood glucose,and the psychological dimension of intrinsic capacity,with these differences also being statistically significant(p<0.05).Conclusion:Continuous nursing care utilizing telemedicine based on a hospital-community-family model combined with exercise intervention can effectively enhance exercise tolerance and intrinsic capacity in elderly patients with diabetes mellitus complicated by chronic kidney disease,thereby improving their quality of life.The effectiveness of the intervention is positively correlated with the duration of the intervention. 展开更多

Objective To analyze preoperative independent risk factors for complicated appendicitis (CA), and explore the predictive efficacy of serum C-reactive protein (CRP) and fibrinogen for CA, so as to optimize preoperative stratification and individualized treatment of acute appendicitis. Methods A retrospective analysis was performed on 362 pathologically diagnosed adult acute appendicitis patients hospitalized in Qingdao Eighth People's Hospital from 2022 to 2023, including 87 CA patients and 275 uncomplicated appendicitis (UA) patients grouped by postoperative pathology. Baseline demographics, clinical manifestations, serological parameters and abdominal CT features were compared. Univariate analysis, binary Logistic regression and ROC curve were applied to screen risk factors and verify diagnostic values. Results Age, gender and BMI were balanced between two groups (P>0.05). Fever, abdominal rebound tenderness, multiple inflammatory-coagulation indicators, serum albumin and appendiceal fecalith differed significantly between groups (allP<0.05). Elevated white blood cell count, CRP, fibrinogen and appendiceal fecalith were independent CA risk factors (all P<0.05). ROC results revealed CRP (AUC=0.790, cut-off=14.105 mg/L, sensitivity=81.6%, specificity=70.9%) and fibrinogen (AUC=0.832, cut-off=4.12 g/L, sensitivity=60.9%, specificity=86.5%) exerted favorable predictive performance, while fecalith and white blood cell count showed limited diagnostic value alone. Conclusion Appendiceal fecalith and elevated white blood cell count are independent CA risk factors. CRP and fibrinogen serve as reliable preoperative serological biomarkers for CA prediction. Combined assessment of the two indicators, peritoneal signs and CT fecalith findings facilitates early CA identification, improves therapeutic decision-making and reduces postoperative complications. 展开更多

BACKGROUND Distribution of the colonic diverticula differs in different populations,and rightsided colon diverticulitis(RCD)and left-sided colon diverticulitis(LCD)manifest distinct clinical features.Complicated diverticulitis(CD)mostly requires hospitalization and can be treated within a spectrum from observation to surgery.Treatment choice is formed depending on the patient’s general condition,the presence of diffuse peritonitis,the localization of diverticulitis,Hinchey stage,and responsiveness to the prior treatment.Clinical disparities regarding right and LCD also led to the differences in the incidences of both emergency surgery and future elective surgery.AIM To evaluate the clinical features of CD,display the differences according to colonic localizations,and present treatment approaches.METHODS This was a retrospective study from a single centre analysing data from a prospective database.The 253 patients with history of hospitalization for CD were included and divided into two groups:RCD and LCD.To compare the differences between the two groups,the Student’s t-test was used when the parametric test prerequisites were fulfilled,and the Mann-Whitney U test was used when such requirements were not fulfilled.RESULTS The 208(82.2%)patients were found to have LCD,and 45(17.8%)had RCD.The majority of the patients had Hinchey 1A diverticulitis(49.8%).Male gender was significantly more common in patients who underwent surgery for LCD.While persistent abdominal pain was the main prior finding in the conservative treatment of both localizations,surgery was most performed due to abscess in RCD and perforation in LCD.The presence of an accompanying malignancy during colonoscopy was significantly more common in LCD cases who underwent surgery.Hartmann’s procedure was the most performed technique in emergency settings(56.3%),while laparoscopic colectomy with anastomosis was in elective settings(53.9%).In addition,surgery was found to prolong the mean length of hospital stay in LCD patients.CONCLUSION Although diverticulitis is a benign condition,the need for an individualized and evidence-based approach makes management challenging.Localization of the disease has an important role in determining the appropriate treatment. 展开更多

BACKGROUND Complicated crown–root fracture (CRF) involves severe injury to the crown, root,and pulp, and may be accompanied by multiple root fractures. The loss of a toothhas lifelong consequences for children and teenagers, but the maintenance of pulphealth and the calcific healing of multiple root fractures are rarely reported in theliterature.CASE SUMMARY This case reports healing of a permanent tooth with complicated crown–root andadditional root fractures, in which pulp health was maintained. A 10-year-old girlfell and fractured the root of her maxillary left central incisor at the cervical level.After the coronal fragment was repositioned, the tooth was splinted until thetooth was no longer mobile, 2 years later. Eight years after treatment, the toothhas remained asymptomatic with vital pulp and localized gingival overgrowth.Cone-beam computed tomography revealed not only calcified healing of the CRFbut also spontaneous healing in an additional undiagnosed root fracture. Thefracture line on the enamel could not be healed by hard tissue and formed agroove in the cervical crown. It was speculated that the groove was related to thelocalized gingival overgrowth.CONCLUSION This case provides a clinical perspective of the treatment of a tooth with acomplicated CRF and an additional root fracture. 展开更多

Objective: To compare the level of glutathione(GSH) and oxidized glutathione(GSSG),the ratio of GSH/GSSG and the concentration of albumin in plasma of patients with complicated and un-complicated falciparum malaria.Methods: This research was a cross sectional study using comparison analysis with the plasma GSH and GSSG, the ratio of plasma GSH/GSSG and the concentration of plasma albumin as variables. The complicated malaria patients were obtained from Dr. Saiful Anwar Hospital Malang, whereas uncomplicated malaria patients were obtained from the Regency of Pleihari South Kalimantan. Plasma GSH and GSSG levels were determined by the spectrophotometer at the wave length of 412 nm, whereas the concentration of albumin was determined by bromocresol green method in the p H of 4.1.Results: There were no significant differences between the level of plasma GSH and GSSG in complicated and uncomplicated malaria patients, as well as the ratio of plasma GSH/GSSG in the two groups(P = 0.373; P = 0.538; and P = 0.615, respectively, independent ttest). In contrast, the plasma albumin concentration in complicated malaria patients were significantly higher than uncomplicated malaria patients(P = 0.000, Mann Whitney U test).Conclusions: It can be concluded that the average of plasma GSH and GSSG level, also plasma GSH/GSSG ratio in complicated malaria are not different from uncomplicated malaria. Although plasma concentration of albumin in both groups is below the normal range,there is an increase in complicated malaria that might be as compensation of oxidative stress. 展开更多

The geologic conditions of superimposed basins in China are very complicated. This is mainly shown by multi-phase structural evolution, multiple sets of source-reservoir-cap rock combinations, multiple stages of hydrocarbon generation and expulsion from source rocks, multi-cycle hydrocarbon enrichment and accumulation, and multi-phase reservoir adjustment and reconstruction. The enrichment, accumulation and distribution of hydrocarbon is mainly controlled by the source rock kitchen, paleo- anticline, regional cap rock and intensity of tectonic movement. In this paper, the T-BCMS model has been developed to predict favorable areas of hydrocarbon accumulation in complicated superimposed basins according to time and spatial relationships among five key factors. The five factors include unconformity surface representing tectonic balancing （B）, regional cap rock representing hydrocarbon protection （C）, paleo-anticline representing hydrocarbon migration and accumulation （M）, source rock kitchen representing hydrocarbon generation and expulsion （S） and geological time （T）. There are three necessary conditions to form favorable areas of hydrocarbon accumulation. First, four key factors BCMS should be strictly in the order of BCMS from top to bottom. Second, superimposition of four key factors BCMS in the same area is the most favorable for hydrocarbon accumulation. Third, vertically ordered combination and superimposition in the same area of BCMS should occur at the same geological time. The model has been used to predict the most favorable exploration areas in Ordovician in the Tarim Basin in the main hydrocarbon accumulation periods. The result shows that 95% of the discovered Ordovician hydrocarbon reservoirs are located in the predicted areas, which indicates the feasibility and reliability of the key factor matching T-BCMS model for hydrocarbon accumulation and enrichment. 展开更多

BACKGROUND Surgical resection is the preferred method for patients with complex liver cancer.But the tumor is in a special position, the surgery is highly risky, postoperative complications can easily occur, and the prognosis is not ideal.AIM To investigate the effectiveness of surgical resection for complex liver cancer and its influencing factors.METHODS Fifty-seven patients who had complicated liver cancer and underwent surgical resection at our hospital from August 2015 to August 2016 were enrolled in this study. All patients were followed for three years, and their postoperative complications, survival, and factors that impacted their survival were analyzed.RESULTS The total incidence of postoperative complications was 45.61%, and the incidence of pleural effusion was the highest at 28.07%. There were no correlations between the 2-year and 3-year survival rates and sex, age, and Hbs Ag of the patients(P >0.05). In terms of pathological parameters, the 2-year and 3-year survival rates were significantly different according to the presence of a tumor capsule, degree of liver cirrhosis, satellite or focal lesions, hepatic vein thrombosis, portal vein tumor thrombus, and intraoperative blood loss(P < 0.05).CONCLUSIONThe effectiveness of surgical resection for complex hepatocellular carcinoma may be affected by factors such as the presence of a tumor capsule, cirrhosis degree,satellite or focal lesions, hepatic vein embolization, portal vein tumor thrombus,and intraoperative blood loss. Therefore, these factors should be controlled and prevented during surgery to help improve patient survival after surgery. 展开更多

AIM: To evaluate the predisposing factors for peritoneal perforation and intrabiliary rupture and the effects of these complications on surgical outcome in liver hydatid disease.METHODS: A total of 372 patients with liver hydatid cysts who had undergone surgical treatment were evaluated retrospectively. Twenty eight patients with peritoneal perforation, 93 patients with spontaneous intrabiliary perforation, and 251 patients with noncomplicated hydatid cysts were treated in our clinics.RESULTS: When the predisposing factors for complications were evaluated, younger age, superf icial position, and larger cyst dimensions (P 0.05). The overall recurrence rate was 3.8% (14 patients), but there was not any statistical difference among the patient groups (P = 0.13). The early postoperative mortality rate was 1.1%. CONCLUSION: In peritoneally perforated and intrabiliary ruptured cases, the most important steps are irrigation of the peritoneal cavity and clearance of the cystic material from the biliary tree. 展开更多

Natural slopes usually display complicated exposed rock surfaces that are characterized by complex and substantial terrain undulation and ubiquitous undesirable phenomena such as vegetation cover and rockfalls.This study presents a systematic outcrop research of fracture pattern variations in a complicated rock slope,and the qualitative and quantitative study of the complex phenomena impact on threedimensional(3D)discrete fracture network(DFN)modeling.As the studies of the outcrop fracture pattern have been so far focused on local variations,thus,we put forward a statistical analysis of global variations.The entire outcrop is partitioned into several subzones,and the subzone-scale variability of fracture geometric properties is analyzed(including the orientation,the density,and the trace length).The results reveal significant variations in fracture characteristics(such as the concentrative degree,the average orientation,the density,and the trace length)among different subzones.Moreover,the density of fracture sets,which is approximately parallel to the slope surface,exhibits a notably higher value compared to other fracture sets across all subzones.To improve the accuracy of the DFN modeling,the effects of three common phenomena resulting from vegetation and rockfalls are qualitatively analyzed and the corresponding quantitative data processing solutions are proposed.Subsequently,the 3D fracture geometric parameters are determined for different areas of the high-steep rock slope in terms of the subzone dimensions.The results show significant variations in the same set of 3D fracture parameters across different regions with density differing by up to tenfold and mean trace length exhibiting differences of 3e4 times.The study results present precise geological structural information,improve modeling accuracy,and provide practical solutions for addressing complex outcrop issues. 展开更多

AIM:To evaluate the safety and efficacy of Densiron 68 heavy silicone oil (HSO) tamponade for complicated retinal detachment(RD)in Chinese eyes.METHODS:Twenty-one eyes of 21 patients with complicated RD were included in this retrospective study.All patients underwent pars plana vitrectomy with an internal tamponade using Densiron 68 HSO.Anatomical and functional results and complications were evaluated,including retinal status,visual acuity(VA),intraocular pressure(IOP),intraocular inflammation,lens opacity,and HSO emulsification.RESULTS:Allthepatients were followed up for 3mo to1y(5.8±1.16mo).Retinal reattachment was achieved in 19of 21 patients(90.5%).VA improved in 18 of 21 patients(85.7%),from 1.93 logMAR(±0.48)to 1.52 logMAR(±0.45)(P=0.001).Postoperative complications included early dispersion of HSO in 7 eyes(38.8%),cataract in 10 of 18phakic eyes(55.5%),moderate postoperative inflammation reaction in 10 eyes(47.6%),and elevated IOP in 5 eyes(23.8%),all of which were controlled by medication or by surgery.CONCLUSION:Highanatomical and functional success rates can be achieved with primary vitrectomy for complicated RD by using Densiron 68 HSO;however,it should not be ignored that Densiron 68 HSO can cause some complications in the eye. 展开更多

In order to increase productivity and reduce energy consumption of steelmaking-continuous casting(SCC) production process, especially with complicated technological routes, the cross entropy(CE) method was adopted to optimize the SCC production scheduling(SCCPS) problem. Based on the CE method, a matrix encoding scheme was proposed and a backward decoding method was used to generate a reasonable schedule. To describe the distribution of the solution space, a probability distribution model was built and used to generate individuals. In addition, the probability updating mechanism of the probability distribution model was proposed which helps to find the optimal individual gradually. Because of the poor stability and premature convergence of the standard cross entropy(SCE) algorithm, the improved cross entropy(ICE) algorithm was proposed with the following improvements: individual generation mechanism combined with heuristic rules, retention mechanism of the optimal individual, local search mechanism and dynamic parameters of the algorithm. Simulation experiments validate that the CE method is effective in solving the SCCPS problem with complicated technological routes and the ICE algorithm proposed has superior performance to the SCE algorithm and the genetic algorithm(GA). 展开更多

A heterogeneous lamella(HL)design strategy was applied to manipulate mechanical properties of a new cost-effective Fe35Ni35Cr25Mo5compositionally complicated alloy(CCA).The HL structure was produced by single-step heat treatment(800℃for 1 h)after cold rolling.This HL structure consists of alternative lamellae regions of coarse-grained FCC matrix(5-20μm),and regions containing ultra-fine grains or subgrains(200-500 nm)together with nanoprecipitates(20-500 nm)and annealing twins.As compared with other cost-effective CCAs,the 800℃annealed sample with HL structure demonstrated a comparable tensile property,with yield strength over 1.0 GPa and total elongation of~13%.Formation of the annealing twins and nanoprecipitates decorated HL structure was a result of the concurrent partial recrystallization and precipitation ofσphase at the shear bands with a high density of lattice defects(e.g.high-density dislocation walls and deformation twins).The latter restricted the growth of recrystallized grains,leading to the formation of ultrafine subgrains within the HL structure.The high yield strength resulted from the multistage hetero-deformation induced(HDI)strengthening and precipitation strengthening associated with heterogeneous lamella structures containing nanoprecipitates.The ductility was originated from the coexistence of multiple deformation mechanisms,which started with dislocation slip and formation of stacking faults at the initial stage,followed by nano-twinning at the higher strain level.This HL design strategy,comprising composition and thermomechanical process designs,and the resultant microstructure tuning,open a broader window for the development of cost-effective CCAs with enhanced performance. 展开更多

In this paper, the characteristics of different forms of mild slope equations for non-linear wave are analyzed, and new non-linear theoretic models for wave propagation are presented, with non-linear terms added to the mild slope equations for non-stationary linear waves and dissipative effects considered. Numerical simulation models are developed of non-linear wave propagation for waters of mildly varying topography with complicated boundary, and the effects are studied of different non-linear corrections on calculation results of extended mild slope equations. Systematical numerical simulation tests show that the present models can effectively reflect non-linear effects. 展开更多
