Hierarchical Phenotyping and Graph Modeling of Spatial Architecture in Lymphoid Neoplasms [PDF]
arXiv, 2021 The cells and their spatial patterns in the tumor microenvironment (TME) play a key role in tumor evolution, and yet the latter remains an understudied topic in computational pathology. This study, to the best of our knowledge, is among the first to hybridize local and global graph methods to profile orchestration and interaction of cellular components.

Companding algorithm for the detection of malignant lesions in HDR CT mandibular images [PDF]
arXiv, 2020 Compressing and expanding (companding) HDR computerized tomography (CT) images to a single LDR image is still a relevant challenge. Besides the general need for simplification of the window setting method for the purpose of diagnosis, there are specific clinical needs for the resection of malignant lesions in the mandible, for example, where the ...

Studying the emergence of invasiveness in tumours using game theory [PDF]
, 2008 Tumour cells have to acquire a number of capabilities if a neoplasm is to become a cancer. One of these key capabilities is increased motility which is needed for invasion of other tissues and metastasis. This paper presents a qualitative mathematical model based on game theory and computer simulations using cellular automata.

Current concepts in diagnosis of unusual salivary gland tumors
Dental Research Journal, 2012 Salivary gland tumors are relatively uncommon and account for approximately 3-6% of all neoplasms of the head and neck. Tumors mostly involve the major salivary glands, 42.9-90% of which occur in the parotid glands and 8-19.5% in the sub-mandibular ...
