Neuroblastomas are sometimes associated with abnormal constitutional karyotypes, but the XYY karyotype has been rarely described in neuroblastomas.Here, we report a case of an esthesioneuroblastoma in a boy with a 47, XYY karyotype.A 6-year-old boy was admitted to our hospital because of nasal obstruction and palpable cervical lymph node, which he
The article presents the analysis of complex stress states in the concrete structure of lipgloss grain silos, caused by non-centric emptying.The authors present a combination of loads from the pressure of bulk solid on the silo chamber according to Eurocode 1, Part 4 [11], which should be taken into account when emptying on large eccentricities in
The surface modification of wool fibers is an important part of the textile industry to add functionality and stability to wool products.In this study, we developed a process utilizing a base/cationic surfactant solution pretreatment followed by an enzyme-mediated keratin crosslinking Quickstrikes reaction to modify the wool fibers.Changes in water
Existing road extraction methods based on deep learning often struggle with distinguishing ground objects that share similar spectral information, such as roads and buildings.Consequently, this study proposes a dual encoder-decoder deep neural network to address road extraction in complex backgrounds.In the feature extraction stage, the first encod
