Full Clinical Pathological and Bacteriological Investigation of a Giant Nasal Polyp Associated With the Developing Apex of the Permanent Fourth Premolar (Triadan 108) in a 3‐year‐old Connemara Filly: A Case Report

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
A 3‐year‐old Connemara X filly presented with unilateral nasal discharge and facial swelling. Diagnostic imaging revealed a soft tissue mass with mineralisation and dental pathology (108). Histopathology confirmed a fibro‐inflammatory polyp. This case highlights a rare equine sino‐nasal polyp associated with endodontic disease, demonstrating a ...

Expanding the Tephrochronological Record in the Alps: Discovery of the Laacher See Tephra in Lake Plansee (Austria)

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract We present the first documented occurrence of the Laacher See tephra (LST) in the Eastern Alps, identified in lake Plansee, Austria. The LST is a key chronostratigraphic marker for correlating and dating Late Glacial sedimentary archives. This discovery was made by progressively narrowing down observational limits from rough estimates of ...

Study on Compound Percussive Drilling: Rock‐Breaking Mechanism of High Confining Pressure Formation in the East China Sea

Energy Science & Engineering
The effect of improving the depth of penetration (ROP) in deep, high‐confining pressure formation is closely related to the rock‐breaking method, which has become a bottleneck restricting the efficient development of oil and gas.

Abrasion Patch Dehydration Experiment at Bright Angel, Jezero Crater, Using SuperCam Onboard the Mars 2020 Perseverance Rover

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract Investigating the stability of hydrated minerals is integral for examining the preservation of rocks for potential Mars Sample Return and has major implications for models that use rover‐based observations to quantify Mars' global water budget.

Study of Frictional Effects of Granite Subjected to Quasi-Static Contact Loading

Lubricants, 2020
The rock fragmentation response to drilling, in particular percussive drilling, is important in order to improve the efficiency of such an operation. The resulting problem includes spherical contact between the drill bit and the material and therefore, a
