Secure and Efficient Authentication Protocol for Underwater Wireless Sensor Network Environments Using PUF

Applied Sciences
Underwater wireless sensor networks (UWSNs) are increasingly used in marine monitoring and naval coastal surveillance, where limited bandwidth, long propagation delays, and physically exposed nodes make efficient authentication critical.

Successful Endoscopic Submucosal Dissection for Giant Inflammatory Fibroid Polyp in Terminal Ileum

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT A 55‐year‐old woman presented with postprandial abdominal pain and diarrhea. Contrast‐enhanced abdominal computed tomography revealed a large tumor in the ileocecal region. Colonoscopy demonstrated a pedunculated polyp originating from the terminal ileum, intermittently prolapsing into the cecum with a stalk‐like base.

Clinicopathological Features of Superficial Non‐Ampullary Duodenal Epithelial Tumors Involving Brunner's Glands

DEN Open, Volume 6, Issue 1, April 2026.
Clinicopathological features of superficial non‐ampullary duodenal epithelial tumors involving Brunner's glands Abstract Background and Aims Although Brunner's glands (BGs), located in the submucosa of the duodenum, may be involved by tumor cells of superficial non‐ampullary duodenal epithelial tumors (SNADETs), the detailed incidence and ...

Underwater Hunting in an Arboreal Snake: Predation Notes on Amazonian Frog Larvae

Ecology and Evolution, Volume 16, Issue 4, April 2026.
We report novel underwater hunting behaviour in a canopy‐dwelling species of snake, the Common Green Racer (Chlorosoma viridissimum). The snake is seen diving and foraging in phytotelmata (water‐filled tree holes), feeding on tadpoles of treefrogs (Trachycephalus resinifictrix, T. hadroceps, and Osteocephalus oophagus). These findings contribute to our

Precision 3D Underwater Electric Field Measurement Method for Accurate Marine Localization

IEEE Access
This paper proposes a method to calibrate the axis misalignment of underwater electric field sensors (EFSs) for the accurate measurement of electric field signals induced by underwater objects and for the precise localization of the objects. We devised a

A Fluorogenic Biosensor for Direct Detection of Vibrio vulnificus, a Climate Change Biomarker

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
Nanoporous anodic alumina (S2) loaded with rhodamine B and capped with a specific oligonucleotide probe (O1) for the vvhA gene. In the presence of V. vulnificus genomic DNA, probe displacement opens the pores and releases the dye, generating a measurable fluorescent signal.

A UAV‐based deep learning pipeline for intertidal macrobenthos monitoring: Behavioral and age classification in Tachypleus tridentatus

Remote Sensing in Ecology and Conservation, Volume 12, Issue 2, Page 242-259, April 2026.
The endangered tri‐spine horseshoe crab (Tachypleus tridentatus), a “living fossil” crucial to coastal ecology and biomedical research, is experiencing severe population declines. Effective conservation requires efficient monitoring, which traditional methods cannot deliver at scale. We develop an integrated UAV deep learning framework tailored to this
