Prospective acquisition correction for head motion with image‐based tracking for real‐time fMRI

In functional magnetic resonance imaging (fMRI) head motion can corrupt the signal changes induced by brain activation. This paper describes a novel technique called Prospective Acquisition CorrEction (PACE) for reducing motion‐induced effects on magnetization history. Full three‐dimensional rigid body estimation of head movement is obtained by image‐based motion detection to a high level of accuracy. Adjustment of slice position and orientation, as well as regridding of residual volume to volume motion, is performed in real‐time during data acquisition. Phantom experiments demonstrate a high level of consistency (translation < 40μm; rotation < 0.05°) for detected motion parameters. In vivo experiments were carried out and they showed a significant decrease of variance between successively acquired datasets compared to retrospective correction algorithms.

Towards Problem Solving Methods in Multi-agent Systems

Problem Solving Methods (PSM) are abstract structures that describe specific reasoning processes employed to solve a set of similar problems and have proved very effective at enhancing reuse and extensibility in developing knowledge-based systems. We envisage that off-the-shelf PSMs can similarly assist in the development of agent-oriented solutions using Multi-Agent Systems (MAS). A challenge towards the effective use of PSMs in MAS is that current approaches to formulating PSMs do not adequately address the complexity of problems to which agent-oriented systems are suited. Towards addressing this, this paper focuses on providing an approach to guide developers in adequately formulating PSMs for complex problemsolving where interactions are involved, such as in domains where negotiation and cooperation are essential for solving a problem.
Attentional Effects on Phenomenological Appearance: How They Change with Task Instructions and Measurement Methods

It has been reported that exogenous cues accentuate contrast appearance. The empirical finding is controversial because non-veridical perception challenges the idea that attention prioritizes processing resources to make perception better, and because philosophers have used the finding to challenge representational accounts of mental experience. The present experiments confirm that when evaluated with comparison paradigms exogenous cues increase the apparent contrast. In addition, contrast appearance was also changed by simply changing the purpose of a secondary task. When comparison and discrimination reports were combined in a single experiment there was a behavioral disassociation: contrast enhanced for comparison responses, but did not change for discrimination judgments, even when participants made both types of judgment for a single stimulus. That a single object can have multiple simultaneous appearances leads inescapably to the conclusion that our unitary mental experience is illusory.
Reliability of the 12-step ascend and descend test and its correlation with motor function in people with chronic stroke.

OBJECTIVE To investigate: (i) the intra-rater, inter-rater and test-retest reliability of the 12-step stair test; (ii) its correlation with other stroke-specific impairments; and (iii) the cut-off scores that best discriminate patients with stroke from healthy elderly subjects. DESIGN Cross-sectional study. SETTING University-based rehabilitation centre. SUBJECTS Thirty-five subjects with chronic stroke and 29 healthy elderly subjects. METHODS The 12-step ascend and descend test was administered along with the Fugl-Meyer Motor Assessment for the lower extremities (FMA-LE), hand-held dynamometer measurements of hip abductor and knee extensor muscle strength, the Five Times Sit to Stand Test (FTSTST), assessment using the Berg Balance Scale (BBS), activities-specific balance confidence scale (ABC) assessment, the 10-metre walk test, and the Timed "Up and Go" (TUG) test. RESULTS The 12-step ascend and descend test showed excellent intra-rater, inter-rater and test-retest reliability. The test was positively correlated with FTSTST times, gait velocity, and TUG times, and negatively correlated with FMA-LE scores and BBS scores. A test performance of 15.22 seconds or less was shown reliably to discriminate healthy elderly subjects from stroke survivors. CONCLUSION The 12-step ascend and descend test is a reliable clinical test that is inexpensive and easy to implement, and is useful for assessing the stair-walking ability of patients with chronic stroke.
Intestinal metabolism of rye lignans in pigs

To study the intestinal metabolism of lignans, the concentrations of plant and mammalian lignans in intestinal digesta sampled along the intestinal tract of pigs were determined by isotope dilution GC–MS. The pigs were fed rye-bread diets made from either whole rye-grains or rye-grain milling fractions enriched in pericarp–testa, aleurone or endosperm cells. The content and characteristics of dietary fibre varied between diets and had been shown to induce different colon fermentation patterns. As the metabolism of lignans depends on the action of the intestinal flora, we tested whether the rye-bread diets influence the metabolism of lignans. In the ileum, the lignans were mainly present as conjugated plant lignans, which were determined only when the analytical procedure included a hydrolysis step. High recovery of dietary lignans in the ileum may indicate that the lignans enter the enterohepatic circulation. In addition, two to three times the intake of lignans were recovered in the faeces when the diets had a high content of dietary fibre suggesting underestimation of plant lignans in the diet. Most of the plant lignans disappeared from the intestinal tract between the terminal ileum and the caecum. The intestinal concentrations and the disappearance of lignans correlated with the content of lignans in the diet, being highest on the pericarp–testa diet and lowest on the endosperm diet. No effect of fermentation pattern on the intestinal metabolism of lignans was observed. The lignans were liberated from the pericarp–testa diet although the plant cell walls remained largely undegraded.
Left ventricular diastolic dysfunction and plasma asymmetric dimethylarginine concentration in persons with essential hypertension

Introduction The study aimed to evaluate the relationship between plasma asymmetric dimethylarginine (ADMA) concentration and development of left ventricular diastolic dysfunction (LVDD) in patients with essential hypertension (EH). Moreover, an attempt was made to define independent risk factors of LVDD in patients with EH. Material and methods A group of 106 individuals with EH was obtained (mean age: 47.18 ±11.76 years). Two groups of patients were distinguished: group I – individuals with EH with LVDD (n = 57); group II – persons with EH without LVDD (n = 49). Echocardiographic examination was conducted by the transthoracic technique. High-performance liquid chromatography was used to measure dimethylarginine concentrations. Results In the group suffering from EH with LVDD, mean ADMA concentration was significantly higher and the ratio of arginine to ADMA was significantly lower than in patients with EH without LVDD. No significant differences were detected between mean concentrations of plasma symmetric dimethylarginine concentration (SDMA) and arginine or in arginine/SDMA ratios in the studied groups. Independent factors of LVDD risk in the study group included higher plasma ADMA concentration, higher serum low-density lipoprotein (LDL) concentration, higher values of body mass index (BMI), higher values of left ventricular mass index (LVMI) and higher values of mean blood pressure (mBP) (ORADMA = 1.731; ORLDL = 1.188; ORBMI = 1.056; ORLVMI = 1.062; ORmBP = 1.014; p < 0.05). Conclusions The results of this study showed that ADMA concentration may be of prognostic value in relation to manifestation of LVDD in patients with EH.
SEMI-SPHERICAL CERAMIC FOAM BURNERS AND BURNING SIMULATION ( PART II )

In this study, a semi-spherical ceramic foam burner for a small capacity boiler was developed. For the burning simulation, the solid model of the semi-spherical foam burner was constituted and the mathematical model related to the system was made.The programmes PrePDF, GAMBIT and FLUENT 6.0 were used to get the simulation. The burning simulation in mixture was done for the static pressure distribution, the velocity distribution, and the temperature distribution.The turbulence ratio is 95%, and the inlet velocity is 10 m/s for the uniform temperature on the surface of the semispherical ceramic foam burner.
Capacity Management in Agricultural Commodity Processing and Application in the Palm Industry

This paper studies the capacity investment decisions of an agri-processor that uses a commodity input to produce a commodity output and a byproduct. Using a multiperiod model, we study the one-time processing and (output) storage capacity investment decisions, and the periodic processing and inventory decisions in the presence of input and output spot price uncertainties and uncertain production yield. We identify three capacity investment strategies, investing in storage-dominating, processingdominating or mixed portfolio, and provide conditions under which each strategy is optimal. Using a calibration based on the palm industry, we provide rules of thumb for capacity management: The processor should decrease its processing capacity with an increase in price correlation; and with an increase (a decrease) in input or output price volatility when this volatility is low (high). The storage capacity should be adjusted in a similar fashion only as a response to a change in output price volatility, otherwise it should not be altered. We nd that not accounting for the byproduct revenue or inventory holding possibility in capacity planning leads to sizeable prot loss. Ignoring production yield uncertainty has a signicant negative impact on protability if the capacity planning is made based on the maximum yield possible, as often done in practice; but it has an insignicant impact if the planning is made based on the average yield.
The Effects of Electrode Configuration on Body Channel Communication Based on Analysis of Vertical and Horizontal Electric Dipoles

The effects of electrode configuration on body channel communication (BCC) are studied for the development of body channel characteristics, such as frequency response, path loss, and resilience to other interferers. First, this paper introduces nine types of electrode configurations according to the arrangement and direction of both transmitting and receiving electrodes on the body. Each configuration is then modeled by means of vertical and horizontal electric dipoles. From Maxwell's equations, the complete equations of vertical and horizontal electric fields on the human body, followed by the ratios of the received electric field to the transmitted electric field, are obtained to find the theoretical body channel characteristics and the effect of electrode configurations on the body channel. The theory is verified with measurement results using a network analyzer and balun transformer. In addition to the channel characteristics, the influence of BCC and RF interference on the body channel is investigated and discussed along with receiving electrode configurations. Based on the measurement results, we found that vertical electrodes in the transmitter and horizontal electrodes with longitudinal direction in the receiver is the optimal configuration for BCC in regard to transmission gain, environmental sensitivity, and interference resilience. Finally, we suggest an effective parameter for BCC, which is equivalent reference distance to determine the proper electrode size for the required frequency response. The relation between the parameter and the electrode size is formulated for the purpose of proper electrode utilization in the design of BCC systems as well as in many potential applications.
Adolescent NSSI and Recovery

We examined how family functioning and emotion regulation strategies relate to both a history of nonsuicidal self-injury (NSSI) and recovery from NSSI. Participants were 272 adolescents aged between 12 and 18 years (M = 14.50 years, SD = 1.46 years), of whom 17.6% reported a history of NSSI. As expected, poor family functioning was associated with engagement in NSSI. Among the emotion regulation variables, higher use of self-blame and lower use of refocus on planning was associated with NSSI. Self-blame and refocus on planning also mediated the relationship between family functioning and NSSI. Similarly, better family functioning and adaptive emotion regulation were related to recovery, while maladaptive emotion regulation was negatively related to recovery. Adaptive emotion regulation moderated the relationship between family functioning and NSSI recovery. We discuss how family-based interventions combined with emotion regulation education may help deter NSSI engagement.
Staurosporine-Induced Apoptosis of Cultured Rat Hippocampal Neurons Involves Caspase-1-Like Proteases as Upstream Initiators and Increased Production of Superoxide as a Main Downstream Effector

We induced apoptosis in cultured rat hippocampal neurons by exposure to the protein kinase inhibitor staurosporine (30 nm, 24 hr). Treatment with the antioxidant (±)-α-tocopherol (100 μm) or the superoxide dismutase-mimetic manganese tetrakis (4-benzoyl acid) porphyrin (1 μm) significantly reduced staurosporine-induced cell death. Using hydroethidine-based digital videomicroscopy, we observed a significant increase in intracellular superoxide production that peaked 6–8 hr into the staurosporine exposure. This increase occurred in the absence of gross mitochondrial depolarization monitored with the voltage-sensitive probe tetramethylrhodamine ethyl ester. We then prepared extracts from staurosporine-treated hippocampal neurons and monitored cleavage of acetyl-Tyr-Val-Ala-Asp-aminomethyl-coumarin and acetyl-Asp-Glu-Val-Asp-AMC, fluorogenic substrates for caspase-1-like and caspase-3-like proteases, respectively. Staurosporine caused a significant increase in caspase-1-like activity that preceded intracellular superoxide production and reached a maximum after 30 min. Caspase-3-like activity paralleled intracellular superoxide production, with peak activity seen after 8 hr. Treatment with the corresponding caspase-3-like protease inhibitor acetyl-Asp-Glu-Val-Asp-aldehyde (10 μm) prevented the increase in caspase-3-like activity and staurosporine-induced nuclear fragmentation, but failed to prevent the rise in superoxide production and subsequent cell death. In contrast, treatment with caspase-1-like protease inhibitors reduced both superoxide production and cell death. Of note, antioxidants prevented superoxide production, caspase-3-like protease activity, and cell death even when added 4 hr after the onset of the staurosporine exposure. These results suggest a scenario of an early, caspase-1-like activity followed by a delayed intracellular superoxide production that mediates staurosporine-induced cell death of cultured rat hippocampal neurons.
Pyrrolnitrin and Hydrogen Cyanide Production by Pseudomonas chlororaphis Strain PA23 Exhibits Nematicidal and Repellent Activity against Caenorhabditis elegans

Pseudomonas chlororaphis strain PA23 is a biocontrol agent able to suppress growth of the fungal pathogen Sclerotinia sclerotiorum. This bacterium produces an arsenal of exometabolites including pyrrolnitrin (PRN), phenazine (PHZ), hydrogen cyanide (HCN), and degradative enzymes. Production of these compounds is controlled at both the transcriptional and posttranscriptional levels by the Gac-Rsm system, RpoS, PsrA, and the Phz quorum-sensing system. Beyond pathogen-suppression, the success of a biocontrol agent is dependent upon its ability to establish itself in the environment where predation by bacterivorous organisms, including nematodes, may threaten persistence. The focus of this study was to investigate whether PA23 is able to resist grazing by Caenorhabditis elegans and to define the role played by exoproducts in the bacterial-nematode interaction. We discovered that both PRN and HCN contribute to fast- and slow-killing of C. elegans. HCN is well-established as having lethal effects on C. elegans; however, PRN has not been reported to be nematicidal. Exposure of L4 stage nematodes to purified PRN reduced nematode viability in a dose-dependent fashion and led to reduced hatching of eggs laid by gravid adults. Because bacterial metabolites can act as chemoattractants or repellents, we analyzed whether PA23 exhibited attractant or repulsive properties towards C. elegans. Both PRN and HCN were found to be potent repellents. Next we investigated whether the presence of C. elegans would elicit changes in PA23 gene activity. Co-culturing the two organisms increased expression of a number of genes associated with biocontrol, including phzA, hcnA, phzR, phzI, rpoS and gacS. Exoproduct analysis showed that PHZ and autoinducer signals were upregulated, consistent with the gene expression profiles. Collectively, these findings indicate that PA23 is able to sense the presence of C. elegans and it is able to both repel and kill the nematodes, which should facilitate environmental persistence and ultimately biocontrol.
Performance of rolling shutter and global shutter camera in optical camera communications

Optical Camera Communication (OCC) is considered as an extension of IEEE 802.15. 7 specification by same communication channel. Different with another technique, Optical Camera Communication used image sensor for receiver, so the characteristic of image sensor will effect on the operation and performance. In this paper we analyze and discuss the performance image sensor characteristic which based on rolling shutter and global shutter technique.
Social Inequalities in Young Children’s Meal Skipping Behaviors: The Generation R Study

Background Regular meal consumption is considered an important aspect of a healthy diet. While ample evidence shows social inequalities in breakfast skipping among adolescents, little is known about social inequalities in breakfast skipping and skipping of other meals among young school-aged children. Such information is crucial in targeting interventions aimed to promote a healthy diet in children. Methods We examined data from 4704 ethnically diverse children participating in the Generation R Study, a population-based prospective cohort study in Rotterdam, the Netherlands. Information on family socioeconomic position (SEP), ethnic background, and meal skipping behaviors was assessed by parent-reported questionnaire when the child was 6 years old. Multiple logistic regression analyses were performed to assess the associations of family SEP (educational level, household income, employment status, family composition) and ethnic background with meal skipping behaviors, using high SEP children and native Dutch children as reference groups. Results Meal skipping prevalence ranged from 3% (dinner) to 11% (lunch). The prevalence of meal skipping was higher among low SEP children and ethnic minority children. Maternal educational level was independently associated with breakfast skipping ([low maternal educational level] OR: 2.21; 95% CI: 1.24,3.94). Paternal educational level was independently associated with lunch skipping ([low paternal educational level] OR: 1.53; 95% CI: 1.06,2.20) and dinner skipping ([mid-high paternal educational level] OR: 0.39; 95% CI: 0.20,0.76). Household income was independently associated with breakfast skipping ([low income] OR: 2.43, 95% CI: 1.40,4.22) and dinner skipping ([low income] OR: 2.44; 95% CI: 1.22,4.91). In general, ethnic minority children were more likely to skip breakfast, lunch, and dinner compared with native Dutch children. Adjustment for family SEP attenuated the associations of ethnic minority background with meal skipping behaviors considerably. Conclusion Low SEP children and ethnic minority children are at an increased risk of breakfast, lunch, and dinner skipping compared with high SEP children and native Dutch children, respectively. Given these inequalities, interventions aimed to promote regular meal consumption, breakfast consumption in particular, should target children from low socioeconomic groups and ethnic minority children. More qualitative research to investigate the pathways underlying social inequalities in children’s meal skipping behaviors is warranted.
Dating Texts without Explicit Temporal Cues

This paper tackles temporal resolution of documents, such as determining when a document is about or when it was written, based only on its text. We apply techniques from information retrieval that predict dates via language models over a discretized timeline. Unlike most previous works, we rely {\it solely} on temporal cues implicit in the text. We consider both document-likelihood and divergence based techniques and several smoothing methods for both of them. Our best model predicts the mid-point of individuals' lives with a median of 22 and mean error of 36 years for Wikipedia biographies from 3800 B.C. to the present day. We also show that this approach works well when training on such biographies and predicting dates both for non-biographical Wikipedia pages about specific years (500 B.C. to 2010 A.D.) and for publication dates of short stories (1798 to 2008). Together, our work shows that, even in absence of temporal extraction resources, it is possible to achieve remarkable temporal locality across a diverse set of texts.
Relationships between aerosols and precipitation in the southern Appalachian Mountains

There are many uncertainties associated with aerosol‐precipitation interactions, particularly in mountain regions where a variety of processes at different spatial scales influence precipitation patterns. Statistical relationships between aerosols and precipitation were examined in the southern Appalachian Mountains to determine the seasonal and synoptic influences on these relationships, as well as the influence of air mass source region. Precipitation events were identified based on regional precipitation data and classified using a synoptic classification scheme developed for this study and published in a separate manuscript (Kelly et al. 2012). Hourly aerosol data were collected at the Appalachian Atmospheric Interdisciplinary Research (AppalAIR) facility at Appalachian State University in Boone, NC (1110 m asl, 36.215°, –81.680°). Backward air trajectories provided information on upstream atmospheric characteristics and source regions. During the warm season (June–September), greater aerosol loading dominated by larger particles was observed, whereas cool season (November–April) precipitation events exhibited overall lower aerosol loading with an apparent influence from biomass burning particles. A significant relationship between aerosol optical properties and precipitation intensity was observed, which may be indicative of aerosol‐induced precipitation enhancement in each season, particularly during warm season non‐frontal precipitation.
The control algorithm for a photovoltaic inverter to be applied in weak power grid

The paper analyzes the power-grid connection for a large and medium photovoltaic (PV) plant in details, and it creates a mathematic model for PV inverter and a parameter model for power distribution. The paper also does some research on the grid-connected character between large PV generation system and weak grid, and it focuses on output voltage and current harmonic while connected. Depending on the simulation result and real operating data of three-phase PV inverter, which founded on the traditional controlling algorithm, the paper proposes a brand new way. The method bases on the space-vector theory, and it can validly decrease the PV grid-connected output voltage and current harmonic, and improve the reliability. The theoretical analysis and partial operation results have proved the correctness of grid-connected features; also, it will provide the theory and grid-connected instruction for Chinese new energy strategy as well as the world.
