Background. Molar pregnancy is an unusual complication of pregnancy whereby abnormal placental tissue proliferates in the absence of a fetus. There is usually a protracted follow- up period where pregnancy is contra- indicated. whilst the medical outcomes of the disease have been well explored, limited data have evaluated the impact on psychological symptomatology, sexual function, and quality of life. Methods. Institutional ethics approval and individual consent were obtained. All women listed on the hospital molar pregnancy register receiving active follow- up (n = 102) and a random sample of women who had been registered in the previous 30 years (n = 56) were sent a postal survey outlining the purpose of the study and an invitation to participate. Questionnaires included the Hospital Anxiety and Depression Scale (HADS), Satisfaction with Life Scale (SwLS), and Sexual History Form 12 (SHF- 12). results. The response rate was 54% . The key findings were that 60% , 55% , and 18% of women scored ≥ 10 on the total HADS, ≥ 8 on HADS- A, and >8 on HADSD, respectively. The presence of children played a protective role and was associated with significantly better psychological function and quality of life. SwLS were in the lower end of ranges reported for community controls (mean of 23.9). Chemotherapy had an adverse impact on quality of life ratings (SwLS for chemotherapy yes = 21.7, no = 25). Sexual dysfunction was similar to community samples and was independent of age, time since diagnosis, chemotherapy requirement, and presence of children. Qualitative results complemented the quantitative data with similar emotional themes identified as well as issues related to the medical condition, care, and support networks. Conclusion. women with a molar pregnancy may benefit from a multidisciplinary approach to management that addresses their psychological and sexual needs in addition to medical aspects of care.

Time averaged consensus in a direct coupled coherent quantum observer network

引用

Control Theory and Technology 2017年第3期15卷 163-176页

作者： Ian r. petersen research School of Engineering The Australian National University Canberra ACT 2601 Australia

This paper considers the problem of constructing a direct coupling quantum observer for a closed linear quantum system. The proposed distributed observer consists of a network of quantum harmonic oscillators and it is shown that the observer network converges to a consensus in a time averaged sense in which each element of the observer estimates the specified output of the quantum plant. An example and simulations are included to illustrate the properties of the observer network.

AIM: To examine the accuracy of the aspartate aminotransferase (AST)/Platelet ratio Index (APrI) and FIB-4, in predicting longitudinal changes in liver histology in hepatitis C virus (HCV) ***: Patients that underwent repeat liver biopsies at least 1 year apart from 1999 to 2007 were identified. Liver fibrosis was staged on needle core biopsies evaluated by a single expert liver pathologist. Only laboratory values within 3 mo of the liver biopsies were ***: Thirty-six patients met the inclusion criteria with 50% stage 1 on initial biopsy, 25% stage 2, and 22% stage 3. Nineteen of 36 (53%) had progression of fibrosis on repeat biopsies, while 16 (44%) showed no change in stage, and one (3%) showed improvement. Patients that showed progression of fibrosis had significantly higher alanine aminotransferase and aspartate aminotransferase levels than the group that did not show progression. A significant correlation was seen between change in stage of fibrosis and change in APrI (r2 = 0.39, P = 0.00001) and a change in FIB-4 (r2 = 0.31, P = 0.00004). A change in APrI (ΔAPrI) of 0.18 had 80% positive predictive value (PPV) and 67% nega- tive predictive value (NPV) for progression of fibrosis. A change in FIB-4 (ΔFIB-4) of 0.39 had 75% PPV and 75% NPV for predicting progression of fibrosis. CONCLUSION: ΔAPrI and ΔFIB-4 parallel changes in fibrosis progression, and could be useful tools for clinicians in following patients with active chronic HCV infection.

The task to estimate all the parameters of an unknown quantum state, also called quantum state tomography, is essential for characterizing and controlling quantum systems. In this paper, we utilize observable time traces to identify the initial quantum state of a closed quantum system, based on the state space approach in the control theory. In the informationally complete scenario, we show that with a linear regression estimation (LrE), the mean squared error (MSE) scales as , where N is the resource number. In the informationally incomplete scenario, we introduce regularization LrE to perform the state tomography task. we employ PBH test to demonstrate that closed quantum systems with only one observable are informationally incomplete and propose using observables, where d is the dimension of the quantum state, for informational completeness. Numerical examples demonstrate the effectiveness of our method.

Theoretical Analysis of the Fluctuation Theorem Applied to Electric Circuits

引用

Communications in Theoretical Physics 2014年第10期61卷 476-484页

作者： Charlotte F.petersen Elmars Krausz Denis J.Evans Stephen r.williams research School of Chemistry Australian National UniversityCanberraACT 0200Australia

we carry out a theoretical analysis of the fluctuations in the Johnson–Nyquist noise in an rC electric circuit being driven by a non-ideal constant current source. Using the appropriate Langevin equation, we derive the fluctuation theorem for the system. This analysis exhibits some interesting features. Firstly, the average of the dissipation function is not necessarily just an instantaneous entropy production, i.e. the work being done on the circuit by the external power source divided by the ambient temperature. Secondly, by appropriate selection of the values for the circuit components,the transient response of the system can be made identical to the nonequilibrium steady state response. In the limit of an ideal current source, the average of the dissipation function reduces to the entropy production. Our analysis accurately reproduces published experimental results.

FerryBox: Using Automated water Measurement Systems to Monitor.water Quality: Perspectives for the Yangtze river and Three Gorges Dam

引用

Journal of Earth Science 2010年第6期21卷 861-869页

作者： Carsten Frank Friedhelm Schroeder.wilhelm petersen Helmholtz-Zentrum Geesthacht GmbH Institute for Coastal Research

The building of the Three Gorges Dam （Hubei （湖北） Province, China） has transformed a region with an economy based on sustainable agriculture for millennia into an entirely different environment within an exceptionally short time. This disrupts the natural biogeochemieal cycles of carbon, nutrients, and metals and possibly will affect the whole catchment including downstream ecosystems, such as wetlands, estuaries, deltas, and adjacent sea areas. Starting from changes that have already been documented, this article concentrates on the possible use of a ＂FerryBox＂, which is an automated water quality measurement system on board a ship or on shore, to monitor the short and long term development of the quality of the river.water in the backwater area and downstream of the dam. while there are already research programmes running to monitor the water quality of the river and the backwater area, these programs are limited to ship campaigns with sampling and laboratory analysis. The spatial and temporal resolution of such measurements is not sufficient for an overall assessment of the water quality and for prognoses in the context of anthropogenic and climate change. Therefore, a concept of applying regular automated observations by a FerryBox is presented. It is shown that such systems are very well suited to give feedback for the assessment of measures to improve the water quality.

Utilizing melt crystallization fundamentals in the development of a new tabletting technology

引用

Frontiers of Chemical Science and Engineering 2014年第3期8卷 346-352页

作者： Ahmed ABOUZEID Sandra petersen Joachim ULrICH Martin Luther University Halle-wittenberg Center for Engineering Science Thermal Process Engineering D-06099 Halle Germany

Increasing production effeciency and lowering costs are some of the many advantages melt crystallization technology offers over the conventional methodology of tabletting. A normal tablet consists of a pure shell or a coat and a separate core constituting the pharmaceutical active ingredient. Great emphasis is put on the purity of the shell since its purpose is to solely protect and deliver the active ingredient to its target. Melt crystallization is a purification （separation） process. It is discussed here for its ability to produce coated tablets, by separating the ＂coating＂ material from the ＂to be coated＂ material coming from one molten mixture. Molten drops of lutrol-ibuprofen mixture are produced using the drop forming technique. The subsequent analysis involves proving and quantifying the phase separation （coat purity）. The mechanism of a crystallizing drop is shown as direct evidence of the ongoing process. Moreover, solidified tablet batches are analyzed for the purity of their coating by measuring the ibuprofen concentration. This optimization process is carried out through multiple stages of development and condition enhancements in order to produce the most pure tablet coating. As a result, a trial showing an almost purely coated tablet is presented here.
