Finding the link of acculturation: the impact of perceived neighbourhood-level residential environment on mental health among rural-to-urban migrants in China.

Background: The mental health of migrants living in the post-migration urban environment poses a significant public health challenge in both developed and developing economies. Few empirical studies attempted to disentangle the influence pathways that acculturation might produce the link between the residential environment and health effects.

Methods: Data from 385 migrants was collected using a multi-stage stratified sampling method from 25 communities in Yiwu, China.

Acceleration control in a dual-stage inertial stabilization system using embedded-parallel-based repetitive-peak compensation.

Acceleration control demonstrates high sensitivity to nonlinear vibrations in the inertial stabilized motion, usually serving as the preferred choice for observation systems in applications like space optical communications, enabling precise tracking and pointing. However, the stabilization performance is limited by the inadequate gain at mid- to high-frequencies in conventional acceleration control, as well as other nonlinear factors like flexibility and backlash. In this paper, an embedded-parallel-based stabilization methodology is proposed for an acceleration-based dual-stage inertial system to achieve additional notch shaping of the sensitivity function.

Utilizing regression model to characterize the impact of urban green space features on the subjective well-being of older adults.

Based on the background of rapid global ageing, research exploring urban green spaces and the subjective well-being of urban residents has become one of the key research interests. However, the evidence for assessing the real benefits of urban green spaces on the subjective well-being of older adults by comprehensively examining the features of urban green spaces is limited. We surveyed older urban green space users (n = 536) aged 60 years and older in Nanjing, China, and evaluated the impacts of spatial, green, and grey features of urban green spaces on older people's overall satisfaction with urban green spaces and subjective well-being.

Parallel-filter-based observer control for unknown multiple narrow-band disturbance rejection.

An observer-based control method with parallel Q-filter is proposed to reject unknown multiple narrow-band disturbances for line of sight stabilization in telescope systems. In general, wide-band or multiple narrow-band disturbances rejection of observer-based control can be transformed into designing Q-filter, which could be too high-order to achieve fully-accuracy digital implementation, resulting in degrading the closed-loop performance or even causing instability. Therefore, a new parallel type of Q-filters is proposed to flexibly adjust the number of Q-filter in the sensitivity function and effectively reduce the computational complexity.

Urban Green Space and Subjective Well-Being of Older People: A Systematic Literature Review.

A growing number of articles have identified and reported the benefits and importance of urban green spaces for improving human well-being, but there is a significant knowledge gap regarding the impact of urban green spaces on the subjective well-being of older adults. The literature search (August 2015-August 2022) was derived from two major scientific databases, Google Scholar, and Web of Science. As a result, 2558 articles were found, 1527 of which were retrieved from WOS and the rest from Google Scholar.

Adaptive Youla-Kučera parametric control of unknown tip-tilt disturbance rejection in image stabilization systems.

We propose a new, to the best of our knowledge, adaptive control method to attenuate beam jitter in image stabilization systems, which breaks the restrictions of existing adaptive control methods in terms of time consumption and control stability, and then provides an innovative way for tip-tilt disturbance rejection. In this approach, disturbance rejection could be converted to optimize error attenuation through the parameters design of the Youla-Kučera (YK) parametric controller, which are determined by a new on-line power spectrum density (PSD) estimation of tip-tilt errors to identify the frequency and amplitude of unknown disturbances. Experimental results demonstrate that the proposed method working in an adaptive correction process can attenuate the beam jitter to approximately 1/3 less than the original control error.

The complete chloroplast genome of B. L. Guo et Hsiao (Berberidaceae).

The genus of belongs to Berberidaceae family, which is famous for their medicinal and ornamental value. In recent years, has attracted increasing attention due to their medicinal and nutritive value. In this research, we reported the complete chloroplast (cp) genome of The complete chloroplast of this species is 157,076 bp in length, including a pair of invert repeat regions (IRS) (25,833 bp) that is divided by a large single copy area (LSC) (88,340 bp) and a small single copy area (SSC) (17,070 bp).
