The synchronization control performance of the Fieldbus system (FCS) is an important guarantee for completion multi-axis collaborative machining tasks, and its accuracy one decisive factors quality. To improve FCS, this paper first makes a comprehensive analysis affecting in FCS. Secondly, by analyzing communication model linear Ethernet, distributed clock compensation method based on timestamp...

BACKGROUND This study validates the Chinese Dementia-Quality of Life instrument (DQoL) in patients with early to moderate stages of Alzheimer's disease (AD) (Clinical Dementia Rating Scale, CDR=0.5, 1, and 2; MMSE >or= 12). METHODS A cross-sectional design was used involving 98 participants (27 controls, 35 patients with questionable dementia (QD), and 36 patients with mild to moderate AD) an...

In an attempt to restore immune competence to 12 human patients. There was a correlation between initial CD4 level and the development of antibodies to FCS (median initial immunodeficiency virus-1 (HIV-1)–infected patients, lymphocytes from their HIV-1–uninfected identical twin siblings CD4 count in FCS antibody positive patients ! 362.0/mL v median initial CD4 count of nonresponders ! 135.0/mL...

The present study examined whether treatment of in vitro matured pig oocytes with calcium ionophore (A23187) could prevent polyspermic penetration in vitro. When oocytes cultured for maturation for 33, 36 or 44 h were subsequently treated with 50 μM A23187 in medium with fetal calf serum (FCS) for 1, 2 and 3 h and then cultured for 12 h without spermatozoa, virtually no activation occurred. In ...

In this paper the properties of a hydrometeorological forecasting system for forecasting river flows have been analysed using a probabilistic forecast convergence score (FCS). The focus on fixed event forecasts provides a forecaster’s approach to system behaviour and adds an important perspective to the suite of forecast verification tools commonly used in this field. A low FCS indicates a more...

Fluorescence correlation spectroscopy (FCS) is a versatile method that would greatly benefit to remote optical-fiber fluorescence sensors. However, the current state-of-the-art struggles with high background and low detection sensitivities that prevent the extension of fiber-based FCS down to the single-molecule level. Here we report the use of an optical fiber combined with a latex microsphere...

uel cell systems offer clean and efficient energy production and are currently under intensive development by several manufacturers for both stationary and mobile applications. The fuel cell (FC) concept dates back to the early 1800s. The idea was first published in [1], and its invention has largely been attributed to W.R. Grove [2]. Although the availability and abundance of fossil fuel has l...

The goal of multiple imputation is to provide valid inferences for statistical estimates from incomplete data. To achieve that goal, imputed values should preserve the structure in the data, as well as the uncertainty about this structure, and include any knowledge about the process that generated the missing data. Two approaches for imputing multivariate data exist: joint modeling (JM) and ful...

OBJECTIVE To adequately help family caregivers (FCs) of cancer patients, clinicians need to understand the complexity of the problems and responsibilities associated with cancer patients illness that FCs experience. METHODS This systematic review identified the types of problems and burdens that FCs of cancer patients experience during the patient's illness. We also analyzed the language care...
