An analysis of U.S. Air Force pilot separation decisions [PDF]

open access: yes, 2010
This thesis analyzes the factors that are associated with separation behavior among United States Air Force pilots. Additionally, the effect of commissioning source on separation was analyzed. Logistic regression models were estimated for U.S.

Role of the Recombination Zone in Organic Light‐Emitting Devices

open access: yesAdvanced Materials, EarlyView.
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

Evaluation of Hearing Loss in Pilots

open access: yesTurkish Archives of Otorhinolaryngology, 2015
Objective:High-intensity noise sources with an increase in air traffic and sudden changes in atmospheric pressure can cause hearing loss in pilots. The main goal of this research is to examine hearing loss due to age, the total flight hours and aircraft ...

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

open access: yesAdvanced Materials, EarlyView.
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Analysis of routine communication in the air traffic control system [PDF]

open access: yes
The present project has three related goals. The first is to describe the organization of routine controller-pilot communication. This includes identifying the basic units of communication and how they are organized into discourse, how controllers and ...

Navigating Ternary Doping in Li‐ion Cathodes With Closed‐Loop Multi‐Objective Bayesian Optimization

open access: yesAdvanced Materials, EarlyView.
The search for advanced battery materials is pushing us into highly complex composition spaces. Here, a space with about 14 million unique combinations is efficiently explored using high‐throughput experimentation guided by Bayesian optimization with a deep kernel trained on both the Materials Project database and our data.
