Relationship between water compartments, body composition assessed by bioelectrical impedance analysis and blood pressure in school children.

BACKGROUND Electrical bioimpedance analysis (BIA) is becoming more widely used in clinical practice as a method of body composition analysis. In healthy children blood pressure (BP) changes with age, body mass and height. Until now the relation between water compartments and BP in healthy children has not been evaluated. The aim of this study was to evaluate the relationship between body composition as well as water compartments (measured by electrical bioimpedance) and BP. METHODS The study was performed in 72 children (32 girls and 40 boys) aged: 6-7 and 12-13 years. BIA measurements were taken using Nutriguard Data Input device with Bianostic electrodes and following parameters were calculated: total body water (TBW), lean body mass (LBM), fat mass (FM), intra- and extracellular water (ICW, ECW) and phase angle alpha. BP was measured twice using the oscillometric method. RESULTS Elevated BP > 95th percentile for gender, age and height were observed in 9 children. A significant correlation between systolic (S)BP and TBW (R = 0.4023, p < 0.001), LBM (R = 0.3600, p = 0.002), FM (R = 0.4725, p < 0.001), ECW (R = 0.4598, p < 0.001) and body mass index (BMI) (R = 0.4089, p < 0.001) was found. Furthermore, diastolic (D)BP significantly correlated with TBW (R = 0.3056, p = 0.011), LBM (R = 0.2783, p = 0.021), FM (R = 0.3956, p < 0.001), ECW (R = 0.3869, p = 0.001) and BMI (R = 0.3550, p = 0.002). In the studied group malnutrition (weight < 3rd percentile) was found in 8 children and 2 had obesity (BMI > 95th percentile). Growth disorders were found in 6 children (5 of them being undernourished). CONCLUSIONS In the studied children SBP and DBP correlated with water compartments, lean body and fat masses derived from BIA. The problem of unrecognized hypertension and malnutrition in children and adolescents is still underestimated in the Polish population.
Bifurcation Analysis of Nonlinear Reaction–diffusion Problems Using Wavelet-based Reduction Techniques

Using a computational method for numerical homogenization, we perform the coarse-scale bifurcation analysis of nonlinear reaction–diffusion problems in both uniform and spatially varying media. The method is based on wavelet decomposition and projection of the differential equation on coarse scale wavelet spaces. The approach is capable of capturing turning points and pitchfork bifurcations of sharp, front-like solutions at the coarse level.
Atypical Employment and Health: A Meta-Analysis

In this meta-analysis we provide new quantitative evidence on the relationship between the characteristics of working contracts and worker's health. We examine 52 studies covering 26 countries in the time period 1984 - 2010 with a combined sample size of 192. We apply a random effects model using odds ratios and their 95\% confidence intervals as measures for the effect size. We distinguish between six types of employment contracts with decreasing security levels (fixed-term, temporary, casual, on-call, daily, no formal contract) and classify the health outcomes into five subgroups (sickness absence, occupational injuries, health-related behavior, mental health and physical health). Furthermore, we control for selected dimensions of the socioeconomic environment of the studies, e.g. the unemployment rate and GDP growth rate. Summary findings show a higher risk of occupational injuries for atypical employees compared to the reference group. Atypical employment increases complaints about mental and physical health and has a negative impact on health-related behavior. Sickness absence works in the opposite direction and permanent employees are more likely to be absent from work. The heterogeneity of the effect sizes between different contracts of atypical employment is low. Effect sizes are country specific and depend on the health outcome indicators. The macroeconomic surrounding - unemployment rate and GDP growth rate - don't cause variation in study results. The 'healthy worker effect' may lead to an overestimation of the impact of workers' atypical employment contract on the health status. More research work which explicitly focuses on the problems of endogeneity, reverse causality and the selection bias is necessary. Furthermore, additional control groups and the employment biography of workers have to be taken into account.
An online trajectory modifier for the base link of biped robots to enhance locomotion stability

This paper proposes an online trajectory modification scheme for biped robots to cope with uncertainty of their environment. The trajectory of the base link in the vertical direction is modified depending on the magnitude of zero moment point deviation from its safety boundary such that appropriate angular moment is generated to maintain stable walking. The modified trajectory then gradually returns to the original trajectory using a 3rd- or 5th-order interpolation polynomial. We expand the gravity-compensated inverted pendulum mode to generate the base-link trajectory not only for single support phases but also double support phases. In the simulations to evaluate the proposed scheme, an impedance controller is used to control a 6-DOF biped robot and the environment of the biped robot is assumed to consist of nonlinear and linear compliant contact models. The simulation results show that the proposed online trajectory modification scheme effectively enhances the stability of locomotion.

This paper describes the results of the CERTH participation in the Synchronization of MultiUser Event Media Task of MediaEval 2014. We used a near duplicate image detector to identify very similar photos, which allowed us to temporally align photo galleries; and then we used time, geolocation and visual information, including the results of visual concept detection, to cluster all photos into different events.
Analysis of wavelet packet and statistical textures for object-oriented classification of forest-agriculture ecotones using SPOT 5 imagery

Textural features of high-resolution remote sensing imagery are a powerful data source for improving classification accuracy because using only spectral information is not sufficient for the classification of objects with within-field spectral variability. This study presents the methods of using an object-oriented texture analysis algorithm for improving high-resolution remote sensing imagery classification, including wavelet packet transform texture analysis, the grey-level co-occurrence matrix (GLCM) and local spatial statistics. Wavelet packet transform texture analysis, with the method of optimization and selection of wavelet texture for feature extraction, is a good candidate for object-oriented classification. Feature optimization is used to reduce the data dimensions in combinations of textural sub-bands and spectral bands. The result of the classification accuracy assessment indicates the improvement of texture analysis for object-oriented classification in this study. Compared with the traditional method that uses only spectral bands, the combination of GLCM homogeneity and spectral bands increases the overall accuracy from 0.7431 to 0.9192. Furthermore, wavelet packet transform texture analysis is the optimal method, increasing the overall accuracy to 0.9216 using a smaller data dimension. Local spatial statistical measures also increase the classification total accuracy, but only from 0.7431 to 0.8088. This study demonstrates that wavelet packet and statistical textures can be used to improve object-oriented classification; specifically, the texture analysis based on the multiscale wavelet packet transform is optimal for increasing the classification accuracy using a smaller data dimension.
Abnormal A-synuclein Interactions with Rab3a and Rabphilin in Diffuse Lewy Body Disease Abnormal Α-synuclein Interactions with Rab Proteins in Α- Synuclein A30p Transgenic Mice

The present study examines A-synuclein interactions with rab3a and rabphilin by antibody arrays, immunoprecipitation and pull-down methods in the entorhinal cortex of control cases and in diffuse Lewy body disease (LBD) cases. A-Synuclein immunoprecipitation revealed A-synuclein binding to rabphilin in control but not in LB cases. Immunoprecipitation with rab3a disclosed rab3a binding to rabphilin in control but not in LB cases. Moreover, rab3a interacted with high molecular weight (66 kDa) A-synuclein only in LB cases, in agreement with parallel studies using antibody arrays. Results were compared with pull-down assays using His 6 /Flag-tagged rab3, rab5 and rab8, and anti-Flag immunoblotting. Weak bands of 17 kDa, corresponding to A-synuclein, were obtained in LB and, less intensely, in control cases. In addition, a-synuclein-immunoreactive bands of high molecular weight (36 kDa) were seen only in LB cases after pull-down assays with rab3a, rab5 or rab8. These findings corroborate previous observations showing rab3a – rabphilin interactions in control brains, and add substantial information regarding decreased binding of rab3a to rabphilin and increased binding of rab3a to A-synuclein aggregates in LB cases. Since, a-synuclein, rab3a and rabphilin participate in the docking and fusion of synaptic vesicles, it can be suggested that exocytosis of neurotransmitters may be impaired in LB diseases. Published by Elsevier Inc. Introduction a-Synuclein is a small, acidic protein containing 140 amino acids which is highly expressed in the brain and which is primarily a-Synuclein contains three modular domains, covering an amino-terminal lipid binding a-helix, an amyloid binding domain that encodes the non-Ah component (NAC) of Alzheimer's disease amyloid plaques and a carboxyl-terminal acidic tail. This structure allows the molecule to exist as a disordered random coil in solution or as a a-helical structure after exposure to acidic phospholipid vesicles (Davidson et al., 1998). The protein associates with many substrates, including fatty acids and lipids, the dopamine transporter, synphilin, tau, microtubule-associated protein 2, tubulin, kinases and presynaptic vesicle membranes (Alim et al. Several studies provide evidence that a-synuclein has a role in synaptic transmission. Marked reduction in the number of vesicles in the vesicle cluster, but not in the docking cluster, is found following anti-sense oligonucleotide a-synuclein ablation methods in fetal rat hippocampal cultures (Murphy et al., 2000). Recent findings have demonstrated that a-synuclein knockout mice show a small reserve and/or resting pool of vesicles and increased synaptic depression during repetitive electrical stimulation (Cabin et al., 2002). These results support the notion that …
A correct security evaluation of quantum key distribution

There is no doubt that quantum key distribution is an excellent result as a science. However, this paper presents a view on quantum key distribution (QKD) wherein QKD may have a difficulty to provide a sufficient security and good communication performance in real world networks. In fact, a one-time pad forwarded by QKD model with $\bar{\epsilon}=10^{-6}$ may be easily decrypted by key estimation. Despite that researchers know several criticisms on the theoretical incompleteness on the security evaluation, Portmann and Rennner, and others still avert from the discussion on criticism, and experimental groups tend to make exaggerated claims about their own work by making it seems that QKD is applicable to commercial communication systems. All such claims are based on a misunderstanding of the meaning of criteria of information theoretic security in cryptography. A severe situation has arisen as a result, one that will impair a healthy development of quantum information science (QIS). Thus, the author hopes that this paper will help to stimulate discussions on developing a more detailed theory.
Investigation of the wet removal rate of black carbon in East 1 Asia : validation of a below-and in-cloud wet removal scheme in 2 FLEXPART v 10 . 4 3

17 Understanding the global distribution of atmospheric black carbon (BC) is essential to unveil its climatic effect. However, 18 there are still large uncertainties regarding the simulation of BC transport due to inadequate information about the removal 19 process. We accessed the wet removal rate of BC in East Asia based on long-term measurements over the 2010–2016 period 20 at three representative background sites (Baengnyeong and Gosan in South Korea and Noto in Japan). The average wet removal 21 rate, represented by transport efficiency (TE), i.e. the fraction of undeposited BC particles during transport, was estimated as 22 0.73 in East Asia from 2010 to 2016. According to accumulated precipitation along trajectory, TE was lower in East and North 23 China, where the industrial sector (thin-coated) is dominant; in contrast, that in South Korea and Japan showed higher values 24 due to the transport sector (thick-coated), with emissions mainly from diesel vehicles. By the same token, TE in winter and 25 summer showed the highest and lowest values, respectively, depending on the dominant emission sectors, such as house heating 26 (thick-coated) and industry. The average half-life and e-folding lifetime of BC were 2.8 and 7.1 days, respectively, similar to 27 previous studies, but those values differed according to the geographical location and meteorological conditions of each site. 28 Next, by comparing TE from the FLEXible PARTicle (FLEXPART) Lagrangian transport model (version 10.4), we diagnosed 29 the scavenging coefficients (s) of the belowand in-cloud scavenging scheme implemented in FLEXPART. The overall 30 median TE from FLEXPART (0.91) was overestimated compared to the measured value, implying underestimation of wet 31 scavenging coefficients in the model simulation. The median of the below-cloud scavenging coefficient showed a lower value 32 than that calculated from FLEXPART, by a factor of 1.7. On the other hand, the overall median of the FLEXPART in-cloud 33 scavenging coefficients was highly underestimated by 1 order of magnitude compared to the measured value. From the analysis 34 of artificial neural networks, the convective available potential energy, which is well known as an indicator of vertical 35 instability, should be considered in the in-cloud scavenging process to improve the representative regional difference in BC 36 wet scavenging over East Asia. For the first time, this study suggested an effective and straightforward evaluation method for 37 wet scavenging schemes (both belowand in-cloud) by introducing TE along with excluding effects from the inaccurate 38 emission inventories. 39 https://doi.org/10.5194/acp-2020-402 Preprint.

Impact of the North Atlantic Oscillation on the Dipole Oscillation of summer precipitation over the central and eastern Tibetan Plateau

An analysis of the spatiotemporal variability in summer precipitation during the period 1961–2010 is presented based on monthly precipitation datasets from 66 meteorological stations in the central and eastern Tibetan Plateau (TP). By applying empirical orthogonal function (EOF) analysis, a strong reversal is found in the variability of summer precipitation between the northeastern and the southeastern TP on the inter‐annual timescale; this reversal is defined as the Dipole Oscillation in summer precipitation over the TP.
KARAKTERISTIK DAN TREN PERUBAHAN SUHU PERMUKAAN LAUT DI INDONESIA PERIODE 1982-2009

Suhu permukaan laut (SPL) merupakan komponen penting yang dapat mengendalikan cuaca dan iklim di wilayah Indonesia. Seiring dengan adanya isu perubahan iklim yang ditandai dengan peningkatan suhu global, maka SPL disinyalir juga berubah. Pada penelitian ini dikaji tentang karakteristik dan tren perubahan SPL di wilayah Indonesia. Tujuan dari penelitian ini adalah untuk mengetahui ada tidaknya perubahan SPL di wilayah Indonesia. Untuk itu dianalisa data SPL selama 28 tahun (1982-2009) dengan metode Mann-Kendall test . Domain yang digunakan adalah 15°LU- 15°LS, 90°BT-145°BT. Berdasarkan hasil penelitian ini diperoleh bahwa karakteristik siklus SPL di wilayah Indonesia berhubungan erat dengan siklus monsun yang bertiup di wilayah ini dimana pada periode monsun Asia SPL di wilayah utara lebih hangat sebaliknya pada periode monsun Australia, di selatan yang lebih hangat dan di sekitar ekuator mengalami SPL paling hangat pada periode peralihan. Secara umum di wilayah Indonesia terutama di inner sea terjadi tren peningkatan SPL dengan probabilitas > 95%. Daerah inlet Arus Lintas Indonesia (ARLINDO) dan South Equatorial Current yang meliputi perairan sekitar Biak, Selat Makassar, Halmahera, dan Laut Banda, pada umumnya mengalami tren peningkatan SPL yang paling tinggi dibandingkan wilayah sekitarnya dengan peningkatan mencapai 0,5-1,1 o C pada periode DJF. Pada masa peralihan dan musim kemarau, hanya di Pasifik bagian barat yang mengalami tren meningkat. Sea Surface Temperature (SST) is an important factor in weather and climate regulation over Indonesia. According to the climate change issue which is characterized by increasing global temperatures, the SST was allegedly increased too. The purpose of this study was to determine the existence of SST change over Indonesia. Mann-Kendall test used to analyze 28 years (1982-2009) SST data. The domain of this research is 15° N-15° S, 90° E-145° E. The result of this research shows that increasing trend of SST occurring over Indonesia waters. It was found that the characteristic of SST in Indonesia is correlated with the monsoon system, whereas in the Asian summer monsoon, the SST of the northern region is warmer. Contrary, in the Australian summer monsoon, the SST of the southern region is warmer. The SST of the equator region is warmest in the transition period. In general, Indonesia's waters experiencing an increasing trend of SST with a probability of over 95%. The Indonesian throughflow and South Equatorial Current on the western part of the Pacific Ocean covering Biak waters, Makassar Strait, Halmahera, and the Banda Sea generally experiencing the highest increasing trend of SST compared with other areas between 0.5 to 1.1°C. In the transitional period and dry season, the SST over Indonesia, largely unchanged, except in the western Pacific.
Left atrial volume and function in patients following ST elevation myocardial infarction and the association with clinical outcome: a cardiovascular magnetic resonance study.

AIMS The left atrium (LA) transfers blood to the left ventricle in a complex manner. LA function is characterized by passive emptying (LA passive fraction), active emptying (LA ejection fraction), and total emptying (LA fractional change). Despite this complexity, the clinical relevance of the LA is based almost exclusively on LA maximal volume (LAmax), which may not glean the full prognostic potential. Cardiovascular magnetic resonance (CMR) is considered the most accurate method for studying LA function and size. The aim of the present study was to evaluate the prognostic importance of LA function in patients following ST elevation myocardial infarction (STEMI). METHODS AND RESULTS In 199 patients, a CMR scan was performed within 1-3 days after STEMI to measure LAmax and minimal volume (LAmin) and LA function. The incidence of death, re-infarction, stroke, and admission for heart failure [major adverse cardiac event (MACE)] were registered during the follow-up period [2.3 years (inter-quartile range: 2.0-2.5)]. A total of 40 patients (20%) met the clinical endpoint of MACE during follow-up. In a Cox regression analysis adjusting for known risk factors, LA fractional change remained independently associated with MACE [adjusted hazard ratio: 0.66 (95% confidence interval: 0.46-0.95)]. LAmax, LAmin, or LA passive fraction was not independently associated with MACE. Furthermore, LA fractional change provided incremental prognostic value to LAmax and other known predictors (Wald χ(2) 31.0 vs. 39.9, P= 0.016). CONCLUSION In STEMI patients, impaired LA fractional change is independently associated with outcome and provide incremental prognostic information to established predictors including LAmax.
Three-loop Universal Anomalous Dimension of the Wilson Operators in N = 4 Susy Yang-mills Model

We present results for the three-loop universal anomalous dimension γ uni (j) of Wilson twist-2 operators in the N = 4 Supersymmetric Yang-Mills model. These results are obtained by extracting the most complicated contributions from the three loop non-singlet anomalous dimensions in QCD which were calculated recently. Their singularities at j = 1 agree with the predictions obtained from the BFKL equation for N = 4 SYM in the next-to-leading order. The asymptotics of γ uni (j) at large j is in an agreement with the expectations based on an interpolation between week and strong coupling regimes in the framework of the AdS/CFT correspondence.
Reconstruction of the reconnection rate from Cluster measurements: Method improvements

[1] A remote-sensing method for reconstructing the reconnection rate and the location of X-line from single-spacecraft observations developed recently is extended to a compressible plasma and an asymmetric magnetic field configuration. The method is based on the two-dimensional analytical model of time-dependent Petschek-type magnetic reconnection. The reconstruction technique is applied to a nightside flux transfer event recorded by Cluster spacecraft in the near-Earth magnetotail on 26 September 2005. The reconnection rate is found to be 3.7–4.8 mV/m; the reconnection distance is around 9–11 Re in the tail.
Shifts and Twists in the Relative Productivity of Skilled Labor: Reconciling Accelerated SBTC with the Productivity Slowdown

Skill-biased technical change is usually interpreted in terms of the efficiency parameters of skilled and unskilled labor. This implies that the relative productivity of skilled workers changes proportionally in all tasks. In contrast, we argue that technical changes also affect the curvature of the distribution of relative productivity. Building on Rosen's (1978) tasks assignment model, this implies that not only the efficiency parameters of skilled and unskilled workers change, but also the elasticity of substitution between skill-types of labor. Using data for the United States between 1963 and 2002, we find significant empirical support for a decrease in the elasticity of substitution at the end of the 70s followed by an increase at the end of the 80s. This pattern of the elasticity of substitution has contributed to the slowdown in labor productivity in the late 70s through the 80s and to a speedup in the 90s
Torrential Rain Forecast using the Mesoscale Model WRF-ARW

episode forecast on January 5-6, 2014 in the province of Khuzestan (Iran) with an advance time of 24, 48 and 72 hours. To find an optimal scheme of forecast we made numerical experiments with six sets of physical parameterizations. During the numerical experiments we were able to identify that the model showed the most sensitivity to cloudiness parameterization. The rating of a forecast made on an independent material showed that the used set of parameterizations of the model WRF-ARW allows to give satisfactory forecasts of heavy rainfall with an advance time of 24 hours.
