Advanced Insights into Goliathus orientalis (Coleoptera: Scarabaeidae) of Tanzania

Advances in Entomology 2024年第2期12卷 129-142页

作者： Gration Mutashoberwa Rwegasira Pasiensi Martin Kayombo Department of Crop Science and Horticulture Sokoine University of Agriculture Chuo Kikuu Morogoro Tanzania Kayomboi Community Group of Researchers in Insects Morogoro Tanzania

Members of the Goliathus group in the order Coleoptera, family Scarabaeidae and the sub-family Cetoniidae is one among essential ecological insects worldwide with scanty documentation in Tanzania. The country was among the first point of collection of the specimen by Moser (1909) but subsequent attempts to locate and collect the specimen were unsuccessful possibly due to changed habitat and behaviour of Goliathus. Much of published work about the insect are based on the morphological characteristics of collected specimen which led to designation of six major species namely;Goliathus goliatus, G. cacicus, G. regius, G. albosignatus, G. orientalis and G. usambarensis, the last two being considered to exist in Tanzania. The current study reports on successful identification of habitats using biological cues and subsequently collected several Goliathus specimen that had been difficult to trace for more than a century. New insights into correct identity of the species by using a combination of morphological and molecular techniques have been set. The study has resolved that only one species, Goliathus orientalis with five sub-species exist in Tanzania.

morphological VARIABILITY OF THE UPPER MISSISSIPPI RIVER

引用

International Journal of Sediment Research 1999年第2期14卷 1-7页

作者： Annie G. BHOWMIK (Principal Scientist and Head, Watershed Science Section, Illinois State Water Survey, 2204 Griffith Drive, Champaign. IL, 61820, USA. E-mail: nbhowmik@uiuc.edu)

This paper very briefly has presented morphometric controls and changes on the UMR. It has shown that geologic controls do play important roles in the morphological variability of a river. However. human influences such as river training works, navigation structure, and alteration in the land also play important roles. morphological features of any river can also undergo drastic changes due to extreme flooding events such as the 1993 Flood on the UMR.

Robust Magnification Independent Colon Biopsy Grading System over Multiple Data Sources

Computers, Materials & Continua 2021年第10期69卷 99-128页

Automated grading of colon biopsy images across all magnifications is challenging because of tailored segmentation and dependent features on each magnification.This work presents a novel approach of robust magnification-independent colon cancer grading framework to distinguish colon biopsy images into four classes:normal,well,moderate,and poor.The contribution of this research is to develop a magnification invariant hybrid feature set comprising cartoon feature,Gabor wavelet,wavelet moments,HSV histogram,color auto-correlogram,color moments,and morphological features that can be used to characterize different grades.Besides,the classifier is modeled as a multiclass structure with six binary class Bayesian optimized random forest(BO-RF)classifiers.This study uses four datasets(two collected from Indian hospitals—Ishita Pathology Center(IPC)of 4X,10X,and 40X and Aster Medcity(AMC)of 10X,20X,and 40X—two benchmark datasets—gland segmentation(GlaS)of 20X and IMEDIATREAT of 10X)comprising multiple microscope magnifications.Experimental results demonstrate that the proposed method outperforms the other methods used for colon cancer grading in terms of accuracy(97.25%-IPC,94.40%-AMC,97.58%-GlaS,99.16%-Imediatreat),sensitivity(0.9725-IPC,0.9440-AMC,0.9807-GlaS,0.9923-Imediatreat),specificity(0.9908-IPC,0.9813-AMC,0.9907-GlaS,0.9971-Imediatreat)and F-score(0.9725-IPC,0.9441-AMC,0.9780-GlaS,0.9923-Imediatreat).The generalizability of the model to any magnified input image is validated by training in one dataset and testing in another dataset,highlighting strong concordance in multiclass classification and evidencing its effective use in the first level of automatic biopsy grading and second opinion.

Area and volume ratios for prediction of visual outcome in idiopathic macular hole

引用

International Journal of Ophthalmology(English edition) 2017年第8期10卷 1255-1260页

作者： Xing-Yun Geng Hui-Qun Wu Jie-Hui Jiang Kui Jiang Jun Zhu Yi Xu Jian-Cheng Dong Zhuang-Zhi Yan The Institute of Biomedical Engineering School of Communication and Information EngineeringShanghai University Department of Medical Informatics Medical School of Nantong University Department of Ophthalmology Affiliated Hospital of Nantong University

AIM： To predict the visual outcome in patients undergoing macular hole surgery by two novel three-dimensional morphological parameters on optical coherence tomography （OCT）： area ratio factor （ARF） and volume ratio factor （VRF）. METHODS： A clinical case series was conducted, including 54 eyes of 54 patients with an idiopathic macular hole （IMH）. Each patient had an OCT examination before and after surgery. morphological parameters of the macular hole, such as minimum diameter, base diameter, and height were measured. Then, the macular hole index （Mill）, tractional hole index （THI）, and hole form factor （HFF） were calculated. Meanwhile, novel postoperative macular hole （MH） factors, ARF and VRF were calculated by three-dimensional morphology. Bivariate correlations were performed to acquire asymptotic significance values between the steady best corrected visual acuity （BCVA） after surgery and 2D/3D arguments of MH by the Pearson method with two-tailed test. All significant factors were analyzed by the receiver operating characteristic （ROC） curve analysis of SPSS software which were responsible for vision recovery. ROC curves analyses were performed to further discuss the different parameters on the prediction of visual outcome. RESULTS： The mean and standard deviation values of patients＇ age, symptoms duration, and follow-up time were 64.8＋8.9y （range： 28-81）, 18.6＋11.5d （range： 2-60）, and 11.4＋0.4mo （range： 6-24）, respectively. Steady-post-BCVA analyzed with bivariate correlations was found to be significantly correlated with base diameter （r＇0.521, P〈0.001）, minimum diameter （r=0.514, P〈0.001）, MHI （r -0.531, P〈0.001）, THI （r=-0.386, P=-0.004）, HFF （r=-0.508, P〈0.001）, and ARF （r=-0.532, P〈0.001）. Other characteristic parameters such as age, duration of surgery, height, diameter hole index, and VRF were not statistically significant with steady-post-BCVA. According to area under the curve （AUC） values, values of ARF, MHI, HFF, minimum diameter, THI, and base diameter are 0.806, 0.772, 0.750, 0.705, 0.690, and

Larval Instars and Division features of Apriona germari

引用

Plant Diseases and Pests 2014年第4期5卷 1-5页

作者： Le Baothanh Ji Baozhong Liu Shuwen Wang Guoxing Zhang Kai Wu Hua College of Forest Resources and Environment Nanjing Forestry University Vietnam Forestry University The Administration Bureau of Dr. Sun Yat-sen's Mausoleum

Apriona germari larvae were obtained via sample collection in woodland and indoor rearing. In this study, larval instars were divided by Dyar＇s law, and the results showed that the larval stage of A. germari comprised six instars, while the width of head capsule was the best instar-dividing structure. On the basis of instar division, tubercle numbers on the transverse furrow downside of first abdominal dorsal ambulatory ampullae, seta numbers of abdominal telson and lateral seta numbers of mandible were observed and statistically calculated. The accuracy of instar-dividing was verified by comparing with the Dyar＇s law. The coincidence rate of two instar-dividing results was 90. 47%. It is approved that the above morphological features could be used in instar division ofA. germari larvae.
