4Using a stand-level model to predict light absorption in stands with vertically and horizontally heterogeneous canopies显示文摘Background:Forest ecosystem functioning is strongly influenced by the absorption of photosynthetically active radiation(APAR),and therefore,accurate predictions of APAR are critical for many process-based forest growth models.The Lambert-Beer law can be applied to estimate APAR for simple homogeneous canopies composed of one layer,one species,and no canopy gaps.However,the vertical and horizontal structure of forest canopies is rarely homogeneous.Detailed tree-level models can account for this heterogeneity but these often have high input and computational demands and work on finer temporal and spatial resolutions than reguired by stand-level growth models.The aim of this study was to test a stand-level light absorption model that can estimate APAR by individual species in mixed-species and multi-layered stands with any degree of canopy openness including open-grown trees to closed canopies.Methods:The stand-level model was compared with a detailed tree-level model that has already been tested in mixed-species stands using empirical data.Both models were parameterised for five different forests,including a wide range of species compositions,species proportions,stand densities,crown architectures and canopy structures.Results:The stand-level model performed well in all stands except in the stand where extinction coefficients were unusually variable and it appears unlikely that APAR could be predicted in such stands using(tree- or stand-level) models that do not allow individuals of a given species to have different extinction coefficients,leaf-area density or analogous parameters.Conclusion:This model is parameterised with species-specific information about extinction coefficients and mean crown length,diameter,height and leaf area.It could be used to examine light dynamics in complex canopies and in stand-level growth models.David I Forrester Ruben Guisasola Xiaolu Tang Axel T Albrecht Tran Lam Dong Guerric le Maire 2014Forestry Studies in China2014,16,3:1

13Impact of COVID-19 on presentation,management,and outcomes of acute care surgery for gallbladder disease and acute appendicitis显示文摘BACKGROUND The ongoing coronavirus disease 2019(COVID-19)pandemic has significantly disrupted both elective and acute medical care.Data from the early months suggest that acute care patient populations deferred presenting to the emergency department(ED),portending more severe disease at the time of presentation.Additionally,care for this patient population trended towards initial non-operative management.AIM To examine the presentation,management,and outcomes of patients who developed gallbladder disease or appendicitis during the pandemic.METHODS A retrospective chart review of patients diagnosed with acute cholecystitis,symptomatic cholelithiasis,or appendicitis in two EDs affiliated with a single tertiary academic medical center in Northern California between March and June,2020 and in the same months of 2019.Patients were selected through a research repository using international classification of diseases(ICD)-9 and ICD-10 codes.Across both years,313 patients were identified with either type of gallbladder disease,while 361 patients were identified with acute appendicitis.The primary outcome was overall incidence of disease.Secondary outcomes included presentation,management,complications,and 30-d re-presentation rates.Relationships between different variables were explored using Pearson’s r correlation coefficient.Variables were compared using the Welch’s t-Test,Chi-squared tests,and Fisher’s exact test as appropriate.RESULTS Patients with gallbladder disease and appendicitis both had more severe presentations in 2020.With respect to gallbladder disease,more patients in the COVID-19 cohort presented with acute cholecystitis compared to the control cohort[50%(80)vs 35%(53);P=0.01].Patients also presented with more severe cholecystitis in 2020 as indicated by higher mean Tokyo Criteria Scores[mean(SD)1.39(0.56)vs 1.16(0.44);P=0.02].With respect to appendicitis,more patients were diagnosed with a perforated appendix at presentation in 2020[20%(36)vs 16%(29);P=0.02]and a greater percentage were classified as emergent cases using the emergency severity index[63%(112)vs 13%(23);P<0.001].While a greater percentage of patients were admitted to the hospital for gallbladder disease in 2020[65%(104)vs 50%(76);P=0.02],no significant differences were observed in hospital admissions for patients with appendicitis.No significant differences were observed in length of hospital stay or operative rate for either group.However,for patients with appendicitis,30-d re-presentation rates were significantly higher in 2020[13%(23)vs 4%(8);P=0.01].CONCLUSION During the COVID-19 pandemic,patients presented with more severe gallbladder disease and appendicitis.These findings suggest that the pandemic has affected patients with acute surgical conditions.Orly Nadell Farber Giselle I Gomez Ashley L Titan Andrea T Fisher Christopher J Puntasecca Veronica Toro Arana Arielle Kempinsky Clare E Wise Kovi E Bessoff Mary T Hawn James R Korndorffer Jr Joseph D Forrester Micaela M Esquivel 2021World Journal of Gastrointestinal Surgery2021,13,8:0
