Dynamically loading IFC models on a web browser based on spatial semantic partitioning.

Industry foundation classes (IFC) is an open and neutral data format specification for building information modeling (BIM) that plays a crucial role in facilitating interoperability. With increases in web-based BIM applications, there is an urgent need for fast loading large IFC models on a web browser. However, the task of fully loading large IFC models typically consumes a large amount of memory of a web browser or even crashes the browser, and this significantly limits further BIM applications.

[Secondary male hypogonadism induced by sellar space-occupying lesion: Clinical analysis of 22 cases].

Objective: To analyze the clinical characteristics of secondary male hypogonadism induced by sellar space-occupying lesion, explore its pathogenesis, and improve its diagnosis and treatment.

Methods: We retrospectively analyzed the clinical data about 22 cases of secondary male hypogonadism induced by sellar space-occupying lesion, reviewed related literature, and investigated the clinical manifestation, etiological factors, and treatment methods of the disease. Hypogonadism developed in 10 of the patients before surgery and radiotherapy (group A) and in the other 12 after it (group B).
