Multiple studies using various approaches have associated reduced fetal movements (RFM) with stillbirth and small for gestational age infants [1,2]. More recently, RFM has been linked to neurodevelopmental delay and a lack of response to treatment for hypoxicischaemic encephalopathy [3,4]. The relationship between adverse pregnancy or infant outcome is thought to be mediated by placental dysfun...

The physical and generalized sensor models are two widely used imaging geometry models in the photogrammetry and remote sensing. Utilizing the rational function model (RFM) to replace physical sensor models in photogrammetric mapping is becoming a standard way for economical and fast mapping from high-resolution images. The RFM is accepted for imagery exploitation since high accuracies have bee...

OBJECTIVE The aims of this study were evaluation of the association of reduced fetal movements (RFM) and small-for-gestational-age (SGA) birth at term and to explore if fetal and maternal outcomes are different with single vs repeated episodes of RFM and normal fetal assessment test results. STUDY DESIGN This was a retrospective cohort study of all singleton pregnancies referred for RFMs at a...

In recent years, customer lifetime value (CLV) has gained increasing importance in both academia and practice. While many advanced techniques have been proposed, the recency/frequency/monetary value (RFM) segmentation framework, and its related probability models, remain a CLV mainstay. In this article, we demonstrate the de_ciency in RFM as a basis for summarizing customer history (data compre...

Social play and tolerance are positively correlated and playful signals are more freely expressed in egalitarian than in despotic species. Macaque species are organized along a continuum from intolerant to tolerant social systems and, for this reason, they are good models to test some hypotheses about the possible linkage between communication and tolerance. We compared facial playful communica...

INTRODUCTION At present there are no reliable non-traumatic and non- invasive methods to analyse the healing process and loosening status after total hip replacement. Therefore early as well as late loosening of prosthesis and interface component problems are difficult to be found or diagnosed at any time. METHODS In a cadaver study the potential application of Resonance Frequency Monitoring ...

Tropospheric ozone is one of six criteria pollutants regulated by the US EPA, and has been linked to respiratory and cardiovascular endpoints and adverse effects on vegetation and ecosystems. Regional photochemical models have been developed to study the impacts of emission reductions on ozone levels. The standard approach is to run the deterministic model under new emission levels and attribut...

Amplitude-weighted mean velocity from continuous wave (CW) Doppler spectra was used to measure aortic flow (QAo) and left ventricular mitral inflow (QLVin). These flows were used to quantify mitral regurgitation fraction: RFm = (QLVin-QAo).QLVin-1.100(%).QLVin was calculated from the diastolic time integral of amplitude-weighted mean velocity that was derived from CW spectra with the transducer...
