Objective: To assess the associated factors of employment intention among contemporary nursing graduates. Background: In postepidemic era, shortage nurses and decline in rate have garnered significant attention globally. It is crucial to evaluate with intentions graduates address issue nurse shortage. So far, existing research on China has mainly focused examining relationship between individual intentions. However, there a notable lack systematic grounded scientific theories that predicts...

Abstract It has been shown recently that the California Undercurrent (CUC), and possibly poleward eastern boundary currents in general, generate mixing events through centrifugal instability (CI). Conditions favorable for CI are created by strong horizontal shears developed turbulent bottom layers of flowing direction topographic waves. At points abrupt change, like promontories capes, coastal current separates from injects gravitationally stable but dynamically unstable flow into interior....

The calibration of the angle encoder is necessary to improve accuracy measurement in precision rotating devices. Due characteristics situ encoders, self-calibration methods depending on special arrangements multiple scanning heads have been widely used. Conventional works usually arrange a regularly distributed way, generally involving too many heads, especially when more high order Fourier components error are calibrated. This paper presents an optimization-based arrangement method for...

Conventional methods for the calibration of angle encoders typically only consider graduation error encoder's circular scale. However, radial motion scale during its rotation, due to eccentricity and axis rotation motion, can also introduce noticeable errors measurement in most practical applications. Based on analysis influence an optimal-arrangement-based four-scanning-heads separation technique situ self-calibration is presented. This Fourier-based uses basic model measure first-order...

We propose a scheme to realize optical nonreciprocal response and conversion in Tavis-Cummings coupling optomechanical system, where single cavity mode interacts with the vibrational of flexible membrane an embedded ensemble two-level quantum emitters. Due introduction interaction, we find that phases between mechanical mode, as well dopant are correlated each other, further give analytical relationship them. By optimizing system parameters, especially relative phase two paths, optimal can...

Four-scanning-heads error separation method under optimal arrangement has proven useful for measuring the radial motion of axis rotation. This technique is based upon fact that angles read by scanning heads are mainly affected both graduation angle encoder's scale and spindle motion. paper presents a further validation this on high-accuracy air-bearing rotary stage equipped with an encoder six heads. Experiments performed to measure three different four-scanning-heads schemes. The results...
