Parents’ Relative Socioeconomic Status and Paternal Involvement in Chinese Families: The Mediating Role of Coparenting

This study examined the mediating role of coparenting in the association between differences/similarities in paternal and maternal socioeconomic status (SES) and paternal involvement in Chinese families. The sample included 244 couples with children aged 3–7 years. Fathers and mothers reported their individual incomes, educational levels, occupations, and coparenting behavior (measured using the Coparenting Scale), and fathers completed the Father Involvement Questionnaire. Structural equation modeling was performed to examine the associations between SES and paternal involvement. Results suggested that SES indicator measures were outcome specific. Occupational differences/similarities were associated with paternal involvement indirectly, via fathers’ family integrity practices. Income and educational differences/similarities did not affect paternal involvement. The results suggested that the traditional Chinese view that “men are chiefly responsible for activity in society, while women are responsible for the home” has faded.
Dissipative Hamiltonian Realization of Multi-machine Multi-load Power Systems

Port-controlled Hamiltonian system method is very useful in the performance enhancement control of power systems, of which the key step is to model the power system as a dissipative Hamiltonian system, i.e., to complete the dissipative Hamiltonian realization (DHR). This paper proposes a DHR for multi-machine multi-load power systems based on a novel DHR structure for nonlinear differential algebraic systems, with which we derive a sufficient condition for the existence and construction of DHRs with constant structure matrices. An example shows that the proposed DHR can facilitate the excitation controller design of power systems.
Molecular Ion Spectroscopy : New Methods and the Proposed Study of H 2 CO

The novel technique of cavity enhanced velocity modulation spectroscopy has recently been demonstrated as the first general absorption technique that allows for sub-Doppler spectroscopy of molecular ions while retaining ion-neutral discrimination. The previous experimental setup has been further improved with the addition of heterodyne detection in a NICE-OHMS setup. This improves the sensitivity by a factor of 50 while retaining sub-Doppler resolution and ion-neutral discrimination. Calibration was done with an optical frequency comb, and line centers for several N2 lines have been determined to within an accuracy of 300 kHz. © 2011 Optical Society of America OCIS codes: (300.1030) Absorption; (300.6320) Spectroscopy, high-resolution; (300.6460) Spectroscopy, saturation; (300.6380) Spectroscopy, modulation; (300.6390) Spectroscopy, molecular; (300.6340) Spectroscopy, infrared.

Anomaly Detection and Similarity Search in Neutron Monitor Data for Predictive Maintenance of Nuclear Power Plants

Anomaly detection and similarity search in time series data is an area of wide research in the field of data mining. In this paper we introduce a nearest neighbor based technique for performing anomaly detection over time series data. It is based on the observation that any anomalous behavior is surrounded by a large variation in slope of the graph obtained by plotting the time sequence. Time series comprising of the count of delayed neutrons have been analyzed for the purpose of predictive maintenance in nuclear power plants. We aim to identify anomalies in the neutron counts possibly due to leaks in the nuclear reactor channel.
Design of an underactuated anthropomorphic hand with mechanically implemented postural synergies

Neurology shows that human controls dozens of muscles for hand poses in a coordinated manner and such coordination is referred as to a postural synergy. The concept of postural synergies was recently adopted in the control of robotic hands. With the synergies implemented digitally in a controller, all the motors in an anthropomorphic robotic hand can be controlled via a few synergy inputs. Aiming at exploring alternative approaches for synergy realization, this paper proposes to implement the postural synergies using a mechanical transmission unit. Two rotation inputs can be scaled, combined, and mapped to the rotary outputs to drive an anthropomorphic hand, enabling not only various grasping tasks but also a manipulation motion. Synergy synthesis and design of the anthropomorphic hand are firstly presented. The transmission unit as the implementation of the postural synergies is then elaborated. Tests were performed to quantify how well the synergies could be reproduced via this transmission unit. The results suggest it might be promising to construct a low cost yet versatile prosthetic hand by implementing the postural synergies mechanically. Graphical Abstract
A Subsymbolic and Visual Model of Spatial Path Planning

Planning a path to a destination, given a number of options and obstacles, is a common task. We sug- gest a two-component cognitive model that combines retrieval of knowledge about the environment with search guided by visual perception. In the first component, subsymbolic information, acquired during navigation, aids in the retrieval of declarative information representing possible paths to take. In the second component, visual information directs the search, which in turn creates knowledge for the first component. The model is implemented using the ACT-R cognitive architecture and makes realistic assumptions about memory access and shifts in visual attention. We present simula- tion results for memory-based high-level navigation in grid and tree structures, and visual navigation in mazes, varying relevant cognitive (retrieval noise, visual finsts) and environmental (maze and path size) parameters.
G-protein ligands inhibit in vitro reactions of vacuole inheritance

During budding in Saccharomyces cerevisiae, maternal vacuole material is delivered into the growing daughter cell via tubular or vesicular structures. One of the late steps in vacuole inheritance is the fusion in the bud of vesicles derived from the maternal vacuole. This process has been reconstituted in vitro and requires isolated vacuoles, a physiological temperature, cytosolic factors, and ATP (Conradt, B., J. Shaw, T. Vida, S. Emr, and W. Wickner. 1992. J. Cell Biol. 119:1469- 1479). We now report a simple and reliable assay to quantify vacuole-to- vacuole fusion in vitro. This assay is based on the maturation and activation of vacuole membrane-bound pro-alkaline phosphatase by vacuolar proteinase A after vacuole-to-vacuole fusion. In vitro fusion allowed maturation of 30 to 60% of pro-alkaline phosphatase. Vacuoles prepared from a mutant defective in vacuole inheritance in vivo (vac2- 1) were inactive in this assay. Vacuole fusion in vitro required a vacuole membrane potential. Inhibition by nonhydrolyzable guanosine derivatives, mastoparans, and benzalkonium chloride suggest that GTP- hydrolyzing G proteins may play a key role in the in vitro fusion events.
Relationship between aspirin/clopidogrel resistance and intra-stent thrombi assessed by follow-up optical coherence tomography after drug-eluting stent implantation.

AIMS No data exist regarding the relationship between aspirin/clopidogrel resistance and intra-stent thrombi on follow-up optical coherence tomography (OCT) after drug-eluting stent (DES) implantation. The purpose of this study was to evaluate the relationship between aspirin/clopidogrel resistance and intra-stent thrombi on the follow-up OCT in DES-treated patients. METHODS AND RESULTS A total of 308 DES-treated patients who underwent follow-up OCT and simultaneous measurement of aspirin reaction unit (ARU) and P2Y12 reaction unit (PRU) using the VerifyNow assay system were selected for the study. Aspirin and clopidogrel resistance were defined as ARU ≥550 and PRU ≥275, respectively. Intra-stent thrombi were detected in 29 patients (9.4%). The mean time interval from DES implantation to OCT was 195 ± 133 days (202.9 ± 103.0 days for patients with intra-stent thrombi vs. 194.7 ± 136.0 days for patients without intra-stent thrombi; P = 0.750). There were no significant differences between patients with and without intra-stent thrombi with regard to the incidence of aspirin resistance (13.8 vs. 11.1%, respectively; P = 0.630) or clopidogrel resistance (72.4 vs. 50.5%, respectively; P = 0.056). The percentage of uncovered struts was 17.9 ± 15.8% in patients with intra-stent thrombi and 12.7 ± 17.3% in patients without intra-stent thrombi (P = 0.098). Stent length was significantly longer in patients with intra-stent thrombi (22.9 ± 6.0 vs. 19.4 ± 5.0 mm, P = 0.006). Multivariate logistic regression analysis showed that stent length (odds ratio = 1.152, 95% confidential interval 1.025-1.295; P = 0.017) was the only independent risk factor for the presence of intra-stent thrombi on OCT. CONCLUSION This OCT study suggested that the presence of intra-stent thrombi may not be associated with aspirin/clopidogrel resistance in DES-treated patients.
GAMS/LGO Nonlinear Solver Suite: Key Features, Usage, and Numerical Performance

The LGO solver system integrates a suite of efficient global and local scope optimization strategies. LGO can handle complex nonlinear models under ‘minimal’ (continuity) assumptions. The LGO implementation linked to the GAMS modeling environment has several new features, and improved overall functionality. In this article we review the solver options and the usage of GAMS/LGO. We also present reproducible numerical test results, to illustrate the performance of the different LGO solver algorithms on a widely used global optimization test model set available in GAMS.

Different effects of whole milk and a fermented milk with the same fat and lactose content on gastric emptying and postprandial lipaemia, but not on glycaemic response and appetite

Longitudinal studies indicate that milk and fermented milk products lower basal plasma cholesterol concentrations, despite their high content of saturated fat, and therefore have favourable health effects. However, there have been few studies on the postprandial effects of milk products. The present study compared the effect of whole milk with a fermented milk, A-38, on postprandial carbohydrate and lipid metabolism, gastric emptying and appetite. Eight healthy young men participated. On the two test days, they arrived fasting for collection of baseline values before consuming the meals, which for a 75 kg subject consisted of 1·4 litre milk or fermented milk, plus 165 mg [13C]acetate (for later determination of gastric emptying by a [13C]acetate breath test). Lactose (15 g) was added to the A-38 meal to equalize the lactose content. Postprandially the A-38 meal resulted in a slower gastric emptying rate than milk (P>0·001). Furthermore, the A-38 meal resulted in a greater increase and a quicker decrease of the triacylglycerol content in all lipoprotein fractions (LDL-fraction, P>0·05; other fractions, P>0·001) and of the gastrointestinal hormones (cholecystokinin and peptide YY, P>0·05; gastric inhibitory polypeptide and glucagon-like polypeptide-1, P>0·001). There were no significant differences in appetite sensations (measured by visual analogue scale) or in the glucose and insulin response (P<0·10). The slower emptying rate of the liquid phase after the A-38 meal is probably due to the higher viscosity of A-38. The lower and more prolonged triacylglycerol response after the milk meal might be caused by coagulation of milk in the stomach.
Social Uncertainties in Social-Ecological Systems: Policy dynamics in the Dutch Delta Programme

Policy arenas are of major importance for long-term water management. Here, decisions are made. Nevertheless, the uncertainties deriving from the policy arenas have gained very limited attention so far in future studies. We analyse long- term water management in The Netherlands, i.e. the Dutch Delta Programme to identify factors causing shocks and the system's responses to that. We identified a participatory policy structure as a major shock. The results of this shock-system response analysis result in a means to address explicate and include social uncertainties.
Estimation of the Voice Source from Speech Pressure Signals: Evaluation of an Inverse Filtering Technique Using Physical Modelling of Voice Production

Objective: The goal of the study is to use physical modelling of voice production to assess the performance of an inverse filtering method in estimating the glottal flow from acoustic speech pressure signals. Methods: An automatic inverse filtering method is presented, and speech pressure signals are generated using physical modelling of voice production so as to obtain test vowels with a known shape of the glottal excitation waveform. The speech sounds produced consist of 4 different vowels, each with 10 different values of the fundamental frequency. Both the original glottal flows given by physical modelling and their estimates computed by inverse filtering were parametrised with two robust voice source parameters: the normalized amplitude quotient and the difference (in decibels) between the levels of the first and second harmonics. Results:The results show that for both extracted parameters the error introduced by inverse filtering was, in general, small. The effect of the distortion caused by inverse filtering on the parameter values was clearly smaller than the change in the corresponding parameters when the phonation type was altered. The distortion was largest for high-pitched vowels with the lowest value of the first formant. Conclusions: The study shows that the proposed inverse filtering technique combined with the extracted parameters constitutes a voice source analysis tool that is able to measure the voice source dynamics automatically with satisfactory accuracy.
The Drosophila phosphatidylinositol transfer protein encoded by vibrator is essential to maintain cleavage-furrow ingression in cytokinesis

Cytokinesis requires the coordination of cytoskeletal and plasma membrane dynamics. A role for phosphatidylinositol lipids has been proposed for the successful completion of cytokinesis but this is still poorly characterised. Here, we show mutants of the gene vibrator, previously found to encode the Drosophila phosphatidylinositol transfer protein, produce multinucleate cells indicative of cytokinesis failure in male meiosis. Examination of fixed preparations of mutant spermatocytes showed contractile rings of anillin and actin that were of normal appearance at early stages but were larger and less well organised at later stages of cytokinesis than in wild-type cells. Time-lapse imaging revealed sequential defects in cytokinesis of vibrator spermatocytes. In cells that fail cytokinesis, central spindle formation occurred correctly, but furrow ingression was delayed and the central spindle did not become compressed to the extent seen in wild-type cells. Cells then stalled at this point before the apparent connection between the constricted cytoskeleton and the plasma membrane was lost; the furrow then underwent elastic regression. We discuss these defects in relation to multiple functions of phosphoinositol lipids in regulating actin dynamics and membrane synthesis.
Modeling and Analysis of Virtualized Multi-Service Cloud Data Centers with Automatic Server Consolidation and Prescribed Service Level Agreements

Cloud Data Centers (CDC) are developing rapidly and will have a major impact on IT infrastructures in the future for reasons of their low ramp-up costs and service delivery/support capabilities for the users. In this paper CDCs with multi-service application classes are considered which are operated under an automatic server consolidation based on parallel hysteresis methods for server activations/deactivations which have been reported on our previous work. Each class is subjected to an individual SLA, e.g., for the average service delay for non-real-time services or for delay percentiles for services with strict response time constraints, and probabilities for service rejection (loss) or migration. The CDC is modeled by a multi-class server cluster (SC) system, each of them represented by a multi-server queuing system which is controlled by a Finite State machine (FSM) for each class of cloud services. The SC systems are analyzed exactly under Markovian assumptions to receive averages and percentiles of response times and probabilities of loss or migration. The method is novel as it minimizes the energy consumption for servers by an automatic server consolidation strategy while guaranteeing the negotiated SLAs. The method is based on a worst case boundary consideration for the delays of arriving service requests and can be useful to understand the parametric influences and to assess the energy saving gains for multi-tier CDCs.
Component Ranking for Fault-Tolerant Cloud Applications

Cloud computing is becoming a mainstream aspect of information technology. More and more enterprises deploy their software systems in the cloud environment. The cloud applications are usually large scale and include a lot of distributed cloud components. Building highly reliable cloud applications is a challenging and critical research problem. To attack this challenge, we propose a component ranking framework, named FTCloud, for building fault-tolerant cloud applications. FTCloud includes two ranking algorithms. The first algorithm employs component invocation structures and invocation frequencies for making significant component ranking. The second ranking algorithm systematically fuses the system structure information as well as the application designers' wisdom to identify the significant components in a cloud application. After the component ranking phase, an algorithm is proposed to automatically determine an optimal fault-tolerance strategy for the significant cloud components. The experimental results show that by tolerating faults of a small part of the most significant components, the reliability of cloud applications can be greatly improved.
The Impact of Trust on E-Government Services Acceptance: A Study of Users' Perceptions by Applying UTAUT Model

Many governments around the world aim seriously to make their services available online and deliver it to their citizens in professional and secure manner. E-government services aims to improve and facilitate the communication between government and citizens by increasing the usage of Information and Communications Technology ICT in government operations. It will provide all government services in electronic form to all citizens in a timely, easy, high quality and effective manner with great productivity and time savings. However, user acceptance is one of the essential keys for adoption and success of e-government application and services. Many studies emphasize that trust is one of the important factors in the adoption studies of e-government. This paper examines the effect of trust as independent variable of the unified theory of acceptance and use of technology UTAUT model on user's acceptance and use of e-government services in the Kingdom of Saudi Arabia KSA. Based on the amended UTAUT model we study the impact of trust on the adoption of e-government services form citizens' perception.
