This work presents the first experimental investigation of ultrafast dynamics in dielectric bowtie nanocavities, featuring deep‐subwavelength mode confinement. Measurements reveal enhanced two‐photon absorption, sub‐picosecond carrier relaxation, and strong pump–probe interactions, demonstrating clear advantages over conventional nanocavities for low ...

Terahertz All‐Dielectric Maxwell Fisheye Lens Waveguide Crossings via Transformation Optics
All‐silicon terahertz waveguide crossings based on Maxwell fisheye lenses are reshaped using transformation optics to interface with planar waveguides while reducing mode mismatch. Realized via subwavelength perforations in a single etching step, 2 × 2 and 3 × 3 crossings achieve broadband transmission with low loss and ultralow crosstalk across 220 ...

Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

Abstract This narrative review summarizes the collective knowledge on periodontal microbiology, through a historical timeline that highlights the European contribution in the global field. The etiological concepts on periodontal disease culminate to the ecological plaque hypothesis and its dysbiosis‐centered interpretation.

HMGB1 Assists in Overcoming Cisplatin Resistance in Chemoresistant Human Ovarian Cancer Cells
ABSTRACT Cisplatin is one of the most effective chemotherapeutic agents used in the treatment of ovarian cancer. However, the frequent development of cisplatin resistance remains a significant limitation, leading to therapeutic failure and poor patient outcomes.

ABSTRACT An experimental campaign was undertaken to demonstrate the applicability of the Bouc–Wen hysteretic model to describe the hysteretic system of the recent Framatome dimple‐less spacer grid design for Pressurized Water Reactors. The experimental setup subjected a reduced‐length fuel rod, supported at both ends by dimple‐less grids, to forced ...
