We present an extensive parameter survey to study the influence of halo mass profiles on the development of tidal tails in interacting disk galaxies. We model the galaxies using a fixed exponential disk with a central bulge and vary the halo potential over a range of parameters using both the Hernquist and NFW mass distributions, probing the effect of the halo mass, extent and concentration. We...

Dynamic hyperinflation (DH) during exercise occurs in most but not all patients with advanced chronic obstructive pulmonary disease (COPD). It is not known whether the presence or absence of DH has implications for dyspnoea and exercise tolerance. Therefore, we compared detailed ventilatory and sensory responses to exercise in hyperinflators and nonhyperinflators with moderate-to-severe COPD. N...

The angular momentum of the Earth-Moon system was initially dominated by Earth's rotation with a short solar day around 5 hours duration. Since then, Earth gradually transferred through tidal friction to orbit Moon, resulting in an increasing orbital radius and deceleration rotation. Geologic observations deposits can be used verify constrain models lunar evolution. In this work we reexamine ol...

banjarmasin is known as a tidal waterfront city and it is called city of a thousand rivers. thecity level was approximately -16 cm below the sea level and almost a swamp-land. the urbanization and the citydevelopment programs have changed the city’s physical and spatial plan from a wetland to a mainland structure. theissues of the city's transformation have changed the city structure from ...

This paper is concerned with some feasibility issues in mathematical programs with equilibrium constraints (MPECs) where additional joint constraints are present that must be satis ed by the state and design variables of the problems. We introduce su cient conditions that guarantee the feasibility of these MPECs. It turns out that these conditions also guarantee the feasibility of the quadratic...

Supermassive black hole binaries (SMBHBs) are expected by the hierarchical galaxy formation model in ΛCDM cosmology. There is some evidence in the literature for SMBHBs in AGNs, but there are few observational constraints on the evolution of SMBHBs in inactive galaxies and gas-poor mergers. On the theoretical front, it is unclear how long is needed for a SMBHB in a typical galaxy to coalesce. I...

NEW FINDINGS What is the central question of this study? Does the combination of a higher neural respiratory drive and greater dynamic mechanical ventilatory constraints during exercise in healthy women versus men form the mechanistic basis of sex differences in activity-related dyspnoea? What is the main finding and its importance? Sex differences in activity-related dyspnoea in health primari...
