Fine‐Needle Aspiration of Salivary Gland Tumors With Low‐Grade Oncocytic Features: Focusing on Oncocytoma Versus Oncocytic Mucoepidermoid Carcinoma

open access: yesDiagnostic Cytopathology, EarlyView.
ABSTRACT Background Salivary gland fine‐needle aspirates (FNAs) with low‐grade oncocytic features are diagnostically challenging due to the substantial morphologic overlap between benign oncocytic tumors and their malignant mimickers. This study evaluates the diagnostic discriminators, performance, and risk of malignancy of these lesions using the ...

Epithelioid Enigma: Proximal‐Type Epithelioid Sarcoma in Cyst Fluid Cytology

open access: yesDiagnostic Cytopathology, EarlyView.
ABSTRACT Epithelioid sarcoma (ES) is a rare, aggressive soft tissue malignancy with substantial morphologic overlap with other epithelioid neoplasms, creating diagnostic difficulty in cytology specimens. We report proximal‐type ES identified in cyst fluid from a lesion clinically interpreted as an epidermal inclusion cyst or abscess.

Seismic analysis and design of tunnels within fault ground: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
The research methods of seismic response of tunnels within fault ground, including field investigations, analytical solutions, physical experiments, and numerical simulations, and seismic countermeasures are discussed. The present study examines the shortcomings and limitations of the current research and design, and puts forward proposals for future ...

Eccentricity Paces Late Pleistocene Glaciations

open access: yes
Late Pleistocene glacial terminations are caused by rising atmospheric CO2 occurring in response to atmospheric and ocean circulation changes induced by increased discharge from Northern Hemisphere ice sheets.

Investigation on the mechanical behavior of the multiple‐layered lining structure of a water conveyance tunnel with high internal water pressure

open access: yesDeep Underground Science and Engineering, EarlyView.
This study presents large‐scale similarity model testing (geometric ratio 3.6) of an innovative multiple‐layered lining system—comprising exterior precast segments, middle self‐compacting concrete, and an interior steel pipe—for high‐pressure (0.75 MPa) water conveyance tunnels.

Energy evolution‐based damage quantification and failure prediction of fault zone tunnel lining concrete: A novel acoustic emission–strain energy coupling approach

open access: yesDeep Underground Science and Engineering, EarlyView.
This study investigates the damage evolution and failure mechanisms of tunnel lining concrete in active fault zones through uniaxial compression tests integrated with acoustic emission (AE) monitoring. A strong linear correlation is identified between the AE cumulative absolute energy and the total strain energy, providing a reliable energy‐based ...
