WORD: A large scale dataset, benchmark and clinical applicable study for abdominal organ segmentation from CT image [article]

Xiangde Luo, Wenjun Liao, Jianghong Xiao, Tao Song, Xiaofan Zhang, Kang Li, Dimitris N. Metaxas, Guotai Wang, Shaoting Zhang
2022 arXiv   pre-print
Although many efforts in this task, there are still few large image datasets covering the whole abdomen region with accurate and detailed annotations for the whole abdominal organ segmentation.  ...  Whole abdominal organ segmentation plays an important role in diagnosing abdomen lesions, radiotherapy, and follow-up.  ...  We also would like to thank the Shanghai AI Lab and Shanghai SenseTime Research for their high-performance computation support.  ...

Owen revisited: a reappraisal of morphology in evolutionary biology

Alessandro Minelli, Frederick R. Schram
1994 Bijdragen tot de Dierkunde  
We discuss some general patterns seen in the anatomy of animals and in their morphogenesis.  ...  Slack et al. (1993) advanced the concepts of the "zootype", a particular spatial pattern of gene expression, and the "phylotype", a particular stage of embryonic development that expresses the zootype.  ...  Schram Owen revisited 68(1) Cellular organization is of secondary importance in establishing the zootype.  ...

Integrating Segmentation Methods From Different Tools Into a Visualization Program Using an Object-Based Plug-In Interface

Felix Fischer, M Alper Selver, Walter Hillen, Cüneyt Guzelis
2010 IEEE Transactions on Information Technology in Biomedicine  
For an informative rendering, these necessitate the usage of different segmentation methods in a single application, and combining/representing the results together in a proper way.  ...  Thus, it is possible to use different plugins with different interfaces and parameters for the segmentation of different tissues in the same dataset while rendering all of the results together is still  ...  In other words, some segmented objects can be rendered with SR while others with VR at the same time.  ...

2021 arXiv   pre-print
Overall, this work advances convolutional neural network explanation approaches and may aid in the development of trustworthy models for sensitive applications.  ...  We illustrate a previously unrecognized limitation of the popular neural network explanation method Grad-CAM: as a side effect of the gradient averaging step, Grad-CAM sometimes highlights locations the  ...  The authors would like to thank the Duke Protected Analytics Computing Environment (PACE), particularly Mike Newton and Charley Kneifel, PhD, for providing the computing resources and GPUs needed to complete  ...

Arthropod segments and segmentation – lessons from myriapods, and open questions

Alessandro Minelli
2020 Opuscula Zoologica Instituti Zoosystematici et Oecologici Universitatis Budapestinensis  
In the late eighties, the emerging paradigm of ecdysozoan affinities of arthropods prompted a revisitation of the concept of the segment as an archetypical body unit.  ...  The current understanding of the segmental organization of myriapods is dramatically different from the traditional views, due both to fresh research on a number of myriapod species and to progress in  ...  Arthur Wallace, Greg Edgecombe and Giuseppe Fusco kindly provided helpful suggestions on the ms. but are not responsible for the idiosyncratic interpretation of myriapod segmentation defended here.  ...

Hox genes as synchronized temporal regulators: Implications for morphological innovation

Michael Crawford
2003 Journal of Experimental Zoology  
In vertebrates, clusters of Hox genes express in a nested and hierarchical fashion to endow the embryo's segments with discrete identities.  ...  A careful analysis of the morphologies of Hox mutant mice suggests that the genes provide qualitatively different cues during the specification of segments than they do during the development of more recently  ...  If ultrabithorax is added back into these deletion mutants, abdominal segments 2-8 are transformed into reiterated abdominal segment 1, and abdominal segment 9 remains intact (Lawrence and Morata, '94;  ...
