Role of Hearing Loss Genes in the Sensory Epithelia Associated With Meniere Disease

open access: yesSensory Neuroscience, EarlyView.
ABSTRACT Meniere disease (MD) is an inner ear disorder characterized by episodic vertigo, tinnitus, fluctuating sensorineural hearing loss (SNHL), and aural fullness. Its hallmark pathological feature is endolymphatic hydrops. MD shows significant familial clustering in European and East Asian populations, supporting a strong genetic component in ...

Duct fanned shielding design for quadrotors

open access: yes, 2016
The master thesis work involved the design implementation of a duct fanned shielding for Quadrotors. This included the investigation of various settings for duct shielding and to identify the best possible option to safe guard propellers of the quadrotor. In addition, the work focused on improving the aerodynamic efficiency, reducing the mass of flight

Rotating Rake Turbofan Duct Mode Measurement System [PDF]

open access: yes
An experimental measurement system was developed and implemented by the NASA Glenn Research Center in the 1990s to measure turbofan duct acoustic modes. The system is a continuously rotating radial microphone rake that is inserted into the duct.

Resource reallocation across successive systemic innovations: How Rolls‐Royce shaped the evolution of the turbojet, turboprop, and turbofan

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary Despite the importance of resource reallocation in shaping a variety of strategic outcomes, strategy scholars have paid only limited attention to the processes by which firms reallocate their resources across successive systemic innovations.

The Potential Benefits of Advanced Casing Treatment for Noise Attenuation in Utra-High Bypass Ratio Turbofan Engines [PDF]

open access: yes
In order to increase stall margin in a high-bypass ratio turbofan engine, an advanced casing treatment was developed that extracted a small amount of flow from the casing behind the fan and injected it back in front of the fan.

Inter‐Crystal Spacing of Implantable Polymeric Surfaces as a Key Suppressor of Microbial Adhesion.

open access: yesSmall, EarlyView.
Biofilm formation on implantable devices is addressed by controlling inter‐crystal spacing in shape memory polymers. Repeated shape recovery aligns and enlarges crystalline phases and reduces amorphous regions, enhancing bacterial repellency. Three biofilm‐forming bacteria show reduced adhesion, and a one‐year dog bile‐duct model maintains function ...

Numerical simulation and analysis of a ducted-fan drone hovering in confined environments

open access: yesAdvances in Aerodynamics
Ducted-fan drones are expected to become the main drone configuration in the future due to their high efficiency and minimal noise. When drones operate in confined spaces, significant proximity effects may interfere with the aerodynamic performance and ...

Nanomagnetic Hyperthermia Sensitizes Gemcitabine Chemosensitivity in Pancreatic Cancer by Inhibiting HSPB1 to Amplify ACSL4‐Mediated Ferroptosis

open access: yesSmall, EarlyView.
ABSTRACT Pancreatic cancer, one of the most malignant solid tumors with the poorest prognosis, is commonly treated with gemcitabine (GEM)‐based systemic chemotherapy. However, chemoresistance remains a significant therapeutic challenge. Ferroptosis, a novel form of programmed cell death, has demonstrated exceptional susceptibility in chemoresistant ...
