Activity Monitoring Process based on Model-Driven Engineering – Application to Ambient Assisted Living
Authors: Simonin Jacques , Soulas Julie , Lenca Philippe
Published: February 2015

The supervisor of the activities of a system user should benefit from the knowledge contained in the event logs of the user. They allow the monitoring of the sequential and parallel user activities. To make event logs more accessible to the supervisor, we suggest a process mining approach, including first the design of an understanding model of the activities of a system user. The model design is based on the relationships between the event logs and the activities of a system user. An intervention model completes the understanding model to assist the supervisor. The intervention model enables an action of the supervisor on the critical activities, and the detection of anomalies. The models are automatically designed with a model-driven engineering approach. An experiment on a smart home system illustrates this tooled design, where the supervisor is a medical or paramedical staff member.
Online Electromagnetic Filtration of Molten Aluminum Using a Multistage Separator System
Authors: Shu Da , Wang Jun , Sun Baode
Published: February 2015

Electromagnetic filtration is a new method for the removal of micro-sized non-metallic inclusions from molten aluminum by means of an external electromagnetic field. This paper introduces a multistage electromagnetic filtration system using alternating magnetic field and its application in semi-continuous casting of aluminum billets. The inclusion content was quantitatively determined through PoDFA sampling and analysis. Results showed that the average efficiency of the removal of inclusion particles and oxide films could reach 93.8% and 80.9%, respectively. The content of inclusion particles without grain refiner could be decreased to a level of 0.02 mm2/kg aluminum, satisfying the requirements in terms of the cleanliness of high-quality aluminum products.

Published: February 2015

Objective: To evaluate the long-term efficacy of triptorelin 3.75 mg subcutaneously every 6 weeks on the final height in girls with idiopathic central precocious puberty (ICPP).

Methods: Forty females with ICPP received triptorelin 3.75 mg every 6 weeks subcutaneously in our hospital from 2002 to December 2010 and reached their final heights were enrolled. These patients were treated with triptorelin alone (group A, n=17) or triptorelin+recombinant human growth hormone (rhGH) (group B, n=23). Height, weight, annual growth velocity (GV), sexual development, predicted adult height (PAH), and adverse effects were observed. Bone age (BA) and height standard deviation score (SDS) were monitored yearly.

Results: Final adult heights (FAHs) were 159.81±1.20 cm and 161.01±1.02 cm in group A vs. group B, which exceeded target height (THt) by 1.51±1.04 cm, 4.86±0.94 cm, respectively. The values of (FAH-THt), (FAH-PAH posttreatment) showed significant difference between the two groups (p<0.05). FAH was positively correlated with Ht SDS-BA at the end of treatment, THt, course of rhGH treatment, and age of menarche (r2=0.66). Body mass index (BMI) increased after treatment in group B. However, there was no significant tendency of increase compared with healthy children at the same age. Ages of menarche and time to menarche from discontinuation were 11.74±0.16 vs. 12.18±0.15 years and 17.41±1.69 vs. 14.71±1.04 months in two groups.

Conclusion: The FAH was improved effectively by triptorelin 3.75 mg subcutaneously every 6 weeks, and more height gain could be achieved when rhGH was used concomitantly. BMI maintained steadily and ovarian function restored quickly after treatment discontinuation with the age of menarche similar to that of normal children. Neither significant side effect nor polycystic ovary syndrome was observed.

17α-Hydroxylase/17-20 lyase deficiency (17OHD) is a rare form of congenital adrenal hyperplasia. Genetic defects causing combined 17OHD lead to the impaired production of cortisol and sex steroids, accumulation of mineralocorticoids, and compensatory overproduction of pituitary adrenocorticotropic hormone. Consequently, individuals with this enzymatic defect present with both adrenal cortical hyperplasia and variable degrees of hypertension, hypokalemia, and sexual immaturity. The patient was aged 15 years and 3 months and she was diagnosed with 17OHD while she was being evaluated for complaints of delayed puberty. In the present case, p.Y27*(c.81C>A) mutation was revealed in the sequence analysis of the
Pregnancy outcomes among renal transplant recipients and patients with end-stage renal disease on dialysis

Published: February 2015

The purpose of our study is to compare pregnancy outcomes between women with a functioning renal transplant and women with end-stage renal disease (ESRD).

We carried out a population-based retrospective cohort study using the Healthcare Cost and Utilization Project Nationwide Inpatient Sample database from 2006 to 2011. Logistic regression analysis was used to estimate the age-adjusted effect of functioning renal transplant vs. ESRD requiring dialysis on pregnancy outcomes.

We identified 264 birth records to women with a functional renal transplant and 267 birth records to women with ESRD on dialysis among 5,245,452 births. As compared to women with ESRD on dialysis, renal transplant recipients were less likely to have placental abruption [odds ratio, OR 0.23 (95% confidence interval, CI 0.08–0.70)], to receive blood transfusions [OR 0.17 (95% CI 0.09–0.30)], and to have growth-restricted and small-for-gestational-age babies [OR 0.45 (95% CI 0.23–0.85)]. Renal transplant recipients were more likely to have an instrumental delivery [OR 15.38 (95% CI 1.92–123.3)]. Among renal transplant women, there was a trend towards delivery by cesarean section as compared to patients with ESRD [OR 1.31 (95% CI 0.93–1.85)]. However, these results were not statistically significant. Fetal deaths were less likely to occur in women with a renal transplant [OR 0.41 (95% CI 0.17–0.96)]. There were four maternal deaths among patients with ESRD on dialysis and no maternal deaths among renal transplant patients.

Patients with a functional renal graft had an overall lower rate of morbidity and adverse pregnancy complications when compared to patients with ESRD on dialysis.
Multi-day bicycle tour route generation
Authors: Payne Katherine Carl , Dror Moshe
Published: February 2015

In this paper, we describe a procedure for constructing bicycle routes of minimal perceived exertion over a multi-day tour for cyclists of different levels of expertise. Given a cyclist’s origin, destination, selected points of interest she/he wants to visit, and a level of cycling expertise, this procedure generates a multi-day bicycle tour as a collection of successive daily paths that begin and end at overnight accommodations. The objective is to minimize the total perceived exertion. We demonstrate the implementation of this procedure on an example multi-day tour route in California and present the results of a survey designed to evaluate the daily paths constructed. Repeated measures analysis indicated that 108 of the 120 perceived exertion ratings of the routes generated by our method fit the reported perceived exertion levels of 175 avid cyclists who participated in an evaluation survey.

Authors: Wang Yanjie , Chen Hualing , Liu Jiayu , Zhu Zicai , Chang Longfei , Li Dichen , Jia Shuhai
Published: February 2015

Recently, ionic polymer-metal composites (IPMCs), which are becoming an increasingly popular material, have been used as soft actuators because of their inherent properties of light weight, flexibility, softness, especially efficient transformation from electrical energy to mechanical energy with large bending strain response under low activation voltage. This paper mainly focuses on a review on optical and micromanipulation applications of IPMCs as soft actuators. After presenting the general mechanism of sensing and actuating in IPMCs, recent progresses are discussed about the preparation process and practical technologies, especially for aided manufacturing techniques defined as the methods to fabricate IPMC into all kinds of shapes in terms of the demands, which are reviewed for the first time. Then, a number of recent IPMC applications for optical actuators, grippers and catheters are reviewed and investigated in this paper. Further developments and suggestions for IPMCs are also discussed. Extensive previous researches are provided for references in detail.

Carrier Lifetime Enhancement in a Tellurium Nanowire/PEDOT:PSS Nanocomposite by Sulfur Passivation
Authors: Heyman James N. , Sahu Ayaskanta , Coates Nelson E. , Ehmann Brittany , Urban Jeffery J.
Published: February 2015

We report static and time-resolved terahertz (THz) conductivity measurements of a highperformance thermoelectric material containing tellurium nanowires in a PEDOT:PSS matrix. Composites were made with and without sulfur passivation of the nanowires surfaces. The material with sulfur linkers (TeNW/PD-S) is less conductive but has a longer carrier lifetime than the formulation without (TeNW/PD). We find real conductivities at f = 1THz of σTeNW/PD = 160 S/cm and σTeNW/PD-S = 5.1 S/cm. These values are much larger than the corresponding DC conductivities, suggesting DC conductivity is limited by structural defects. The free-carrier lifetime in the nanowires is controlled by recombination and trapping at the nanowire surfaces. We find surface recombination velocities in bare tellurium nanowires (22m/s) and TeNW/PD-S (40m/s) that are comparable to evaporated tellurium thin films. The surface recombination velocity in TeNW/PD (509m/s) is much larger, indicating a higher interface trap density.
Oxygen Activation by N-doped Graphitic Carbon Nanostructures
Authors: Noffke Benjamin W. , Li Qiqi , Li Liang-shi , Raghavachari Krishnan
Published: February 2015

Fundamental understanding of the oxygen reduction reaction (ORR) electrocatalyzed by nitrogen-doped carbon requires a well-defined structure to correlate structure to function. Well-characterized N-doped graphitic nanostructures derived from benzene derivatives have been synthesized in our group, and shown to catalyze a four-electron ORR under alkaline conditions. Density functional theory calculations have been performed on a model N-doped graphitic nanostructure, C50N2H20, to determine an oxygen activation mechanism. With guidance through an experimentally determined Pourbaix diagram, DFT calculations clearly indicate that the catalyst must undergo a 2e−,1H+reduction to generate a reactive carbanionic intermediate that activates oxygen with a spin inversion.

The natural co-infection with dengue virus can occur in highly endemic areas where different serotypes have been observed for many years. We report here four cases of DENV-3/DENV-4 co-infection detected by serological and molecular tests among 674 patients with acute undifferentiated fever from the tropical medicine reference center of Manaus City, Brazil, between 2005 and 2010. Analysis of the sequences obtained indicated the presence of genotype 3 and 1 for DENV-3 and DENV-4 respectively.
A Novel Semiautomatic Technique for Volumetric Assessment of the Alveolar Bone Defect Using Cone Beam Computed Tomography
Authors: Linderup Bo Werner , Küseler Annelise , Jensen John , Cattaneo Paolo M.
Published: February 2015

Objective

The aims of this study were (1) to determine the three-dimensional anatomical boundaries of the alveolar bone defect in cleft lip and palate (CLP) patients, (2) to precisely translate these anatomical boundaries into reliable cephalometric landmarks and planes that can be used for cone beam computed tomography (CBCT) analysis, (3) to standardize image acquisition and reconstruction parameters, and (4) to test the reproducibility of the proposed protocol for measuring the predefined alveolar bone defect, using a third-party software.

Methods

The alveolar bone defect volume of 10 randomly selected patients with unilateral CLP (UCLP) aged 8 years and 6 months to 11 years and 2 months was evaluated on preoperative and 1-year postoperative CBCT scans using a semiautomatic, standardized protocol. The alveolar bone graft outcome was calculated as a percentage of the bone fill using the formula (VOLpre – VOLpost)/VOLpre) × 100. Intra- and interobserver reliability was assessed.

Results

Intra- and interobserver reproducibility was excellent for volumes and bone fill as no statistically significant difference ( P < .001) was seen between the different sets of measurements, and Pearson correlation coefficients were large (intraobserver: r > .9849, interobserver: r > .8784). The Bland-Altman plots indicated that the differences between the plots were not patterned.

Conclusions

Volume determination using CBCT, third-party medical image processing software, and the presently defined image acquisition and reconstruction parameters, including anatomical boundaries, is a reproducible and practical method for assessing the volumetric outcome of secondary alveolar bone grafting in patients with UCLP.

O número de mortos em decorrência de acidentes de trânsito cresce gradualmente a cada ano. Corpos carbonizados e mutilados comumente resultam como produto desta relação causal térmico-traumática. Consequentemente, a Odontologia Legal desempenha papel importante viabilizando o exame cadavérico de tecidos duros remanescentes. Contudo, para que o exame pós-morte seja executado de maneira adequada, faz-se necessária a utilização de dados comparativos ante-mortem com alto grau de confiabilidade e qualidade. Relatar um caso pericial em que a identificação odontolegal uma vítima de acidente de trânsito ficou prejudicada por falhas no preenchimento do prontuário odontológico. Em 2014, duas vítimas fatais de acidente de trânsito foram encaminhadas carbonizadas para identificação humana. A primeira vítima foi identificada por exame de DNA, após verificar-se impossibilidade de identificação papiloscópica e odontológica. Já a segunda vítima, estava viabilizada a análise odontolegal, uma vez que apresentou remanescentes dentais pós-morte e dados terapêuticos registrados em prontuário odontológico. Durante a análise comparativa, discrepâncias foram encontradas no confronto ente os dados detectados no cadáver e registrados no prontuário. Apesar disto, diversas similaridades foram também observadas. Cogitando-se falha humana no preenchimento do prontuário, foram coletas amostras de DNA da segunda vítima para exame de identificação humana. O referido exame resultou em identificação positiva, indicando, também, que o prontuário continha informações erroneamente inseridas. A falha no preenchimento do prontuário odontológico acarreta perícias imprecisas, atrasos nos processos de identificação e, eventualmente, aumento dos custos periciais. Assim, ressalta-se a relevância da conduta ética do Cirurgião-dentista, principalmente durante o preenchimento e guarda do prontuário odontológico.
Transpiration dynamics support resource partitioning in African savanna trees and grasses
Authors: Holdo Ricardo M. , Nippert Jesse B.
Published: February 2015

It is still far from clear whether and to what extent trees and grasses partition soil moisture in tropical savannas. A major reason for this is that we don't know how snapshot data on rooting differences translate into ecologically relevant patterns of water use at seasonal scales. We used stable isotopes in soil and stem water to quantify functional rooting profiles in grasses and two tree species in a South African savanna. Concurrently, we measured tree sap‐flow velocity, grass canopy temperature (a transpiration correlate), and soil moisture content at multiple depths over the course of a growing season. We used lasso regression to identify the dominant soil moisture layers driving daily variation in tree and grass water‐use metrics while controlling for weather variables. We found clear rooting depth differences between grasses (shallow) and trees (deep) from the isotopic data, and these patterns were strongly supported by the water‐use data, which showed that grasses and trees predominantly responded to soil moisture availability at 5 and 40 cm depth, respectively. Our results provide a rare example of mechanistic support for the resource partitioning hypothesis in savannas, with important implications for our understanding of tree–grass dynamics under altered precipitation regimes.
