Development of an advanced pitch active control system for a wide body jet aircraft [PDF]

An advanced PACS control law was developed for a commercial wide-body transport (Lockheed L-1011) by using modern control theory. Validity of the control law was demonstrated by piloted flight simulation tests on the NASA Langley visual motion simulator.

Exact scaling solution of the mode coupling equations for non-linear fluctuating hydrodynamics in one dimension

, 2016
We obtain the exact solution of the one-loop mode-coupling equations for the dynamical structure function in the framework of non-linear fluctuating hydrodynamics in one space dimension for the strictly hyperbolic case where all characteristic velocities

Generation of a Ground‐State Electron Donor Utilizing Stored Light Energy

Chemistry – A European Journal, EarlyView.
Chemically stored light energy enables the generation of dianion reductants (∼−2.7 V) from vicinal diols derived from diaryl ketone photodimerization. These ground‐state electron donors efficiently reduce challenging substrates at room temperature, including aryl bromides, alkyl iodides, and sulfonamides.

Shear behavior of bolt–grout interfaces under constant normal stiffness: Influence of grout strength and thickness

Deep Underground Science and Engineering, EarlyView.
The effects of grout strength and thickness on the shear behavior of bolt–grout interfaces (BGI) under constant normal stiffness conditions are investigated. Shear strength, failure modes, and acoustic emission characteristics are examined. The findings reveal that grout strength exerts a significantly greater influence on BGI shear strength and ...

Social Comparison and Its Association With Disordered Eating Symptoms: A Systematic Review and Meta‐Analysis

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Social comparison has been widely implicated in the etiology and maintenance of body dissatisfaction and eating disorders. At the same time, however, the magnitude of this relationship remains unclear, with existing studies varying widely in methodology, measurement, and sample characteristics.

Effects of pulmonary rehabilitation on ventilation dynamics measured during exertion in patients with post-acute COVID-19 syndrome: A cross-sectional observational study.

PLoS ONE
BackgroundPulmonary rehabilitation (PR) is recommended in people with post-acute COVID-19 syndrome (PACS), although there is a lack of studies evaluating its benefits via the most commonly used primary endpoint: the six-minute walk test (6MWT).

Filtering Trust: Disclosing the Role of Artificial Intelligence Decreases Trust in Technology, but Does Not Prevent Harm to Body Image After Viewing AI‐Generated Content

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objectives Despite the rapid growth of generative artificial intelligence (AI), virtually no research exists examining the psychological impacts of viewing or interacting with AI‐generated images of people. Additionally, it remains relatively unknown whether informing viewers when images are AI‐generated is an effective way to lessen harm or ...
