This study explores how contact angle hysteresis and titling angle relate with stickiness on superhydrophobic surfaces. The result indicates that contact angle hysteresis could not be mentioned as a proper factor to evaluate the surface stickiness. By analyzing the system pinning force of droplet placed on a titled surface, we concluded that both solid fraction and surface geometric factor are ...

Abstract Arcus is a proposed Explorer Class soft X-ray grating spectrometer. It aims to explore cosmic feedback by mapping hot gases within and between galaxies galaxy clusters characterizing jets winds from supermassive black holes investigate the dynamics of protoplanetary disks stellar accretion. features 12 m focal-length grazing-incidence silicon pore optics (SPO) developed for Athena miss...

We use an X-ray stacking technique to investigate the evolution of the mean X-ray luminosity of ∼21,000 red galaxies at 0.3 ≤ z < 0.9 as a function of their stellar mass and redshift. The red galaxies are selected from the 9.3 deg 2 Boötes field of the NOAO Deep Wide-Field Survey (NDWFS). The mean X-ray luminosity is an order of magnitude larger than we would expect from stellar sources alone a...

Introduction: Hand and wrist stability are critical for optimal upper extremity function. Instability occurs when injury or a pathological condition alters balance, typically in the basketball players and handball players. Injury also can occur whenever the ligaments are subjected to tensile forces that exceed their physiological capacities. For example, thumb is stable in ext...

purpose: to compare anterior segment and ocular biometric parameters of unaffected fellow eyes of patients with a previous attack of acute angle closure (aac), primary angle closure suspect (pacs) eyes, and normal eyes; and to assess the risk of developing aac in pacs. methods: in this prospective comparative observational case series, 16 unaffected fellow eyes of patients with a previous attac...

This paper presents the analysis and numerical results of rotation, propagation angle, and attenuation angle upon the waves propagating in the piezoelectric body. Via considering the centripetal and Coriolis accelerations in the piezoelectric equations with respect to a rotating frame of reference, wave velocities and attenuations are derived and plotted graphically. It is demonstrated that rot...
