BACKGROUND Consensus on whether physical condition affects the risk of gravity-induced loss of consciousness (G-LOC) has not been reached, and most previous studies about the issue did not include well-experienced aviators. We compared the physical conditions of well-experienced young aviators according to the occurrence of G-LOC during human centrifuge training. METHODS Among 361 young male ...

BACKGROUND In Chile, overweight and obesity are pressing issues in public health. AIM To identify individual, social and environmental factors that affect the likelihood of adolescents to become overweight or obese. MATERIAL AND METHODS We used physical condition data of a sample of 900 urban eighth grade students from Santiago, obtained in the 2011 National Study of Physical Education. Thi...

Acoustic communication is highly influential in the expression of social behavior by anuran amphibians, transmitting information about the individual's physical condition and motivation. We studied the phonotactic (approach movements) responses of wild and captive male golden mantella frogs to conspecific wild and captive playback calls to determine the impact of captivity on social behaviour m...

The shared decline in cognitive abilities, sensory functions (e.g., vision and hearing), and physical health with increasing age is well documented with some research attributing this shared age-related decline to a single common cause (e.g., aging brain). We evaluate the extent to which the common cause hypothesis predicts associations between vision and physical health with social cognition a...

The extent to which a place feels like a home is related in part to the physical condition of the property and its surrounding environment. Tenants and local authorities have been provided with extensive legal powers to force landlords to remedy defects since the late 19th century. Yet housing conditions within rented property remain poor. Problems relating to the boundaries of legal remedies w...

The original Jaynes-Cummings model is described by a Hamiltonian which is exactly solvable. Here we extend this model by several types of interactions leading to a nonhermitian operator which doesn’t satisfy the physical condition of space-time reflection symmetry (PT symmetry). However the new Hamiltonians are either exactly solvable admitting an entirely real spectrum or quasi exactly solvabl...
