Giant dumbbell tumor of the posterior mediastinum [PDF]
Vojnosanitetski Pregled, 2009 Background. Giant dumbbell-shaped tumors are very rare and characterized by intra- and extraspinal propagation of different dimensions. In thoracal localization, invasive growth can lead up to rib and vertebra erosion. Case report. We presented a 54-year-

Settling of an asymmetric dumbbell in a quiescent fluid
, 2016 We compute the hydrodynamic torque on a dumbbell (two spheres linked by a massless rigid rod) settling in a quiescent fluid at small but finite Reynolds number. The spheres have the same mass densities but different sizes.

Unusual “Dumbbell”-Shaped Hibernoma
Plastic and Reconstructive Surgery - Global Open, 2019 Summary: Hibernoma is considered as a rare soft tissue benign tumor originating from brown fat. Few cases have been described so far in the literature; hibernoma was first described by Merkel in 1906, but it was named by Gery in 1914.

Decoding THz‐Driven Dynamic Fingerprints of Ferroelectric Nanotwin Networks
Advanced Materials, EarlyView.ABSTRACT Ultrafast polarization dynamics in ferroelectrics are of considerable interest for high‐speed tunable dielectrics and electro‐optics. Extended domain wall networks formed in ferroelectric twin nanodomains can support collective dynamics in the terahertz regime but require techniques that track polarization and strain evolution driven by ...

Advanced Materials Interfaces, EarlyView.A simple strategy is presented for bonding acrylic PSAs and silicone elastomers by curing surfactant‐doped Ecoflex on oxygen‐plasma‐treated VHB. The interface reaches a maximum strength of 1.6 N/mm (over 20 times that of the control) while retaining material compliance.

Statistics of polymer adsorption under shear flow
, 2009 Using non-equilibrium Brownian dynamics computer simulations, we have investigated the steady state statistics of a polymer chain under three different shear environments: i) linear shear flow in the bulk (no walls), ii) shear vorticity normal to the ...

Passive Shape‐Adaptive Fluidic Interface for Enhanced Skin‐Sensor Coupling in Wearable Devices
Advanced Materials Technologies, EarlyView.This study presents a passive fluidic interface for wearable biosensors that adapts to static and dynamic body shape changes to maintain consistent skin contact. Flexible, fluid‐filled pouches redistribute pressure from high‐load areas to regions requiring improved contact, enhancing signal quality and comfort in a compact, low‐energy design for ...
