With the increasing emphasis on safeguarding maritime sovereignty and developing marine resources, the security of underwater acoustic communication has risen to a new level of importance. Given the complex environmental challenges faced by underwate...

Introduction: Orbital floor fractures occur commonly as a result of blunt trauma to the face and periorbital region. Orbital floor fractures with a “trapdoor” component allow both herniation and incarceration of contents through a bone defect into th...

The global production of information continuously increases in quantity and variety. However, the tools and technologies developed to handle such large volumes of data have not adequately met the security and privacy requirements. Existing cloud secu...

The passive soil arching effect exists in many soil–grille interaction systems. Increasing mental grillage foundations are used for transmission lines in aeolian sand areas; thus, exploring the evolution mechanism of passive soil arching is cru...

Once thought to be uniquely human, prosocial behavior has been observed in a number of species, including vampire bats that engage in costly food-sharing. Another social chiropteran, Jamaican fruit bats (Artibeus jamaicensis), have been observed to e...

Pancoast tumors, also defined as superior sulcus tumors, still represent a complex clinical condition requiring high technical surgical skills within more articulated multimodality treatment. The morbidity and mortality rates after Pancoast tumor tre...

Cervicothoracic neuroblastomas (NBs) pose unique surgical challenges due to the complexity of the neurovascular structures located in the thoracic inlet. To date, two main techniques have been reported to completely remove these tumours in children:...
