Immunohistochemical investigation of suprabasin, isthmin-1, and podocalyxin immunoreactivity in basal cell carcinoma and trichoblastoma/trichoepithelioma

Objective Basal cell carcinoma (BCC) and trichoblastoma/trichoepithelioma (TB/TE) are skin tumors that may exhibit similar histopathological features. This study aimed to examine the immunoreactivity of suprabasin (SBSN), isthmin-1 (ISM-1), and podocalyxin (PODXL) BCC and TB/TE,...

A SAM2 and VLM-Based Automatic Radiological Reporting System for Pneumothorax Detection

Background/Objectives: Pneumothorax, caused by air accumulation in the pleural space, can lead to lung collapse and, if diagnosis is delayed, respiratory or cardiovascular deterioration. Most deep-learning studies on pneumothorax address classification or segmentation alone. This...

Fault-Diagnosis-Aware Adaptive Policy Switching for Robust Map-Free Mobile Robot Navigation Under Sensor and Control Degradation

Heterogeneous sensor and control degradation can destabilize direct sensor-to-action navigation. This study presents a fault-diagnosis-aware adaptive policy-switching framework that combines a calibrated seven-class temporal health-state classifier with hysteretic routing among n...

Structural, Surface-Chemical and Morphological Control of Effective Thermal Transport in La2O3-Modified ZnO Nanopowder Compacts

Pristine ZnO and ZnO containing 1, 5, 10 and 20 wt.% nominal La2O3 were prepared by sol–gel-assisted chemical precipitation to investigate composition-dependent thermal transport in porous pressed-powder compacts. X-ray diffraction, Fourier-transform infrared spectroscopy, Raman...
