AbstractAlthough the 13C (13Carbon) natural abundance method is used to study soil C dynamics, scanty information is available on long‐term fertilization effects on soil C sequestration rates along with δ13C in surface (0–30 cm) and deep (30–90 cm) soil layers and their relationships with crop productivities in subtropics. Hence, soil aggregation, δ13C in bulk soils and aggregates, C pools, and sequestration rates were studied in an Indian Alfisol under a 43‐year old wheat (Triticum aestivum L.)‐based cropping system. Treatments were as follows: no mineral fertilizer and no manure (unfertilized control), 100% recommended dose of nitrogen (N), 100% N and 100% recommended phosphorus (NP), 100% N, 100% P, and 100% recommended potassium (NPK), NPK + lime (NPKL), 150% recommended NPK (1.5NPK), and NPK + farmyard manure at 10 Mg ha−1 (NPKF). Plots with NPKF contained 50% higher soil organic C than NPKL in surface soil (0–15‐cm layer). In the 0–90‐cm profile, soil organic C accumulation and sequestration rates in NPKF were ~0.15 and 0.11 Mg ha−1 yr−1 higher than NPKL plots, respectively. The NPKF plots had higher glomalin‐related soil protein and greater recalcitrant C than NPKL, 1.5NPK, and NPK in surface soil. The NPKF plots had higher δ13C values within bulk soils and their aggregates than NPKL and NPK. There were significant correlations between deep soil C sequestration rates with mean crop productivities and δ13C with deep soil C sequestration rates. Overall, NPKF application had the largest surface and deep soil C sequestration with highest crop productivity and hence is recommended.

AbstractBackgroundA 30‐year‐old oligoasthenozoospermia man was found to have unbalance mosaic translocation between chromosome 22 and four other chromosomes (5, 6, 13, and 15) during the investigations for a couple with infertility for 3 years, which is a rare event in human pathology.MethodsClassical cytogenetics analysis, fluorescence in situ hybridization (FISH), and chromosome microarray analyses (CMA) were performed on peripheral blood lymphocytes; copy number variation sequencing (CNV‐Seq) analysis was performed on sperm DNA.ResultsClassical cytogenetics analysis showed the presence of six cell lines on peripheral blood lymphocytes: 45, XY, der (13) t(13;22),‐22[10]/46, XY, t(13;22)[6]/45, XY, der(15)t(15;22),‐22[4]/46, XY, t(13;22)[1]/45, XY, der(5)t(5;22),‐22[1]/45, XY, der(6)t(6;22)[1]. FISH and CMA performed on peripheral blood cells showed the presence of a 6.9 Mb mosaic 22q11 deletion (approximately 50% of cells); it is unexpected that the phenotypes of this man were merely oligoasthenozoospermia, mild bradycardia, and mild tricuspid regurgitation. CNV‐Seq analysis performed on sperm DNA revealed the rate of 22q11 deletion cells was obviously lower compared with peripheral blood cells. And the frequency of gametes exhibiting a normal or balance chromosomal equipment was above 80% in sperm samples.ConclusionTo the best of our knowledge, this report is the first case of a de novo gonosomal mosaic of chromosome 22q11 deletion just associated with male infertility.

AbstractBackgroundDisordered inflammation and immune response is an acknowledged risk factor for cervical cancer development. Interleukin‐1 receptor type 2 (IL1R2) is a decoy receptor for IL‐1 cytokines and involved in host inflammatory and immune progression which could lead to the lesion and neoplasia of cervix. In this study, we aimed to evaluate the relationships between IL1R2 polymorphisms and cervical cancer risk in Uygur females from China.MethodsIn this case–control study, genotypes of six selected variants (rs11674595, rs4851527, rs719250, rs3218896, rs3218977, and rs2072472) distributed in IL1R2 were detected among 247 cervical cancer patients and 286 healthy controls with the usage of an Agena MassARRY method. Furthermore, Genetic models and haplotype analyses were conducted to estimate the associations of IL1R2 polymorphisms with cervical cancer risk.ResultsAfter statistical analyses, rs719250 (odd ratio [OR] = 1.436, 95% confidence interval [95% CI] = 1.079–1.911, p = 0.013) and rs3218896 (OR = 1.552, 95% CI = 1.080–2.229, p = 0.017) showed obvious evidence in correlation to cervical cancer susceptibility owing to the surviving significant differences between cases and controls in allele model. Genetic model analyses also revealed significant associations of rs719250 and rs3218896 with cervical cancer risk in the codominant model, the dominant model and the log‐additive model even after adjustment for age (p < 0.05). Moreover, haplotype “T/A” of rs11674595/rs4851527 (adjusted OR = 0.73, 95% CI = 0.54–0.98, p = 0.037) and “T/C” of rs719250/rs3218896 (adjusted OR = 1.61, 95% CI = 1.10–2.36, p = 0.015) exhibited protective and risky effects for Uygur individuals on cervical cancer development, respectively.ConclusionOur data first shed the new light on the associations of IL1R2 polymorphisms with cervical cancer susceptibility among Uygur females. These results are supposed to facilitate the tumorigenesis genetic research among Chinese minorities.
Simple empirical formulas to estimate the dielectric constant and conductivity of concrete
Authors: Jin Xiaohua , Ali Mohammod 
Published: November 2018

AbstractKnowing the frequency‐dependent and moisture‐dependent relative permittivity and conductivity values of concrete is critical to develop a variety of future wireless and radar technologies including sensing, wireless power transfer, and radar imaging. Due to their continuity of two parameters (frequency and moisture content) and based on the existing measurement results of concrete dielectric constant and conductivity in the literature several simple mathematical expressions are developed to estimate the dielectric constant and conductivity of concrete. These formulas can be used to estimate the dielectric constant and conductivity of concrete from just a few MHz to 2 GHz with moisture content varying from 0 % to 10%.

Modified Look‐Locker inversion recovery (MOLLI)T1mapping sequences can be useful in cardiac and liver tissue characterization, but determining underlying waterT1is confounded by iron, fat and frequency offsets. This article proposes an algorithm that provides an independent water MOLLIT1(referred to as on‐resonance waterT1) that would have been measured if a subject had no fat and normal iron, and imaging had been done on resonance. Fifteen NiCl2‐doped agar phantoms with different peanut oil concentrations and 30 adults with various liver diseases, nineteen (63.3%) with liver steatosis, were scanned at 3 T using the shortened MOLLI (shMOLLI)T1mapping, multiple‐echo spoiled gradient‐recalled echo and1H MR spectroscopy sequences. An algorithm based on Bloch equations was built in MATLAB, and water shMOLLIT1values of both phantoms and human participants were determined. The quality of the algorithm's result was assessed by Pearson's correlation coefficient between shMOLLIT1values and spectroscopically determinedT1values of the water, and by linear regression analysis. Correlation between shMOLLI and spectroscopy‐basedT1values increased, fromr = 0.910 (P < 0.001) tor = 0.998 (P < 0.001) in phantoms and fromr = 0.493 (for iron‐only correction;P = 0.005) tor = 0.771 (for iron, fat and off‐resonance correction;P < 0.001) in patients. Linear regression analysis revealed that the determined water shMOLLIT1values in patients were independent of fat and iron. It can be concluded that determination of on‐resonance water (sh)MOLLIT1independent of fat, iron and macroscopic field inhomogeneities was possible in phantoms and human subjects.

AbstractSome N‐tosylhydrazone derivatives were effectively synthesized under solvent‐free conditions by using a grinding method at room temperature. The short reaction time, clean and mild process with simple workup and easy purification of the target compounds were salient features of the present protocol, which enables straightforward access to N‐tosylhydrazones. Among the tosylhydrazone derivatives evaluated, compound 3 l exhibits excellent apoptosis‐promoting and anticancer potential against triple‐negative breast cancer (TNBC) cell lines. This research shows that our synthesized compound 3 l may be a desirable and effective therapeutic drug against TNBC.

SummaryObjectiveANGPTL4 inhibits lipoprotein lipase in adipose tissue, regulating plasma triglycerides levels. In persons with obesity plasma ANGPTL4 levels have been positively correlated with body fat mass, TG levels and low HDL. A loss‐of‐function E40K mutation in ANGPTL4 prevents LPL inhibition, resulting in lower TGs and higher HDLc in the general population. Since obesity determines metabolic alterations and consequently is a major risk factor for cardiovascular disease, the aim was to explore if obesity‐related metabolic abnormalities are modified by the ANGPTL4‐E40K mutation.MethodsANGPTL4‐E40K was screened in 1206 Italian participants, of which 863 (71.5%) with obesity. All subjects without diabetes underwent OGTT with calculation of indices of insulin‐sensitivity.ResultsParticipants with obesity carrying the E40K variant had significantly lower TG (p = 0.001) and higher HDLc levels (p = 0.024). Also in the whole population low TGs and high HDLc were confirmed in E40K carriers. In the obese subpopulation it was observed that almost all E40K carriers were within the lowest quartile of TGs (p = 1.1 × 10−9). E40K had no substantial effect of on glucose metabolism. Finally, none of the obese E40K carriers had T2D, and together with the favourable lipid profile, they resemble a metabolically healthy obese (MHO) phenotype, compared to 38% of E40E wild‐type obese that had diabetes and/or dyslipidaemia (p = 0.0106).ConclusionsIn participants with obesity the ANGPTL4‐E40K variant protects against dyslipidemia. The phenotype of obese E40K carriers is that of a patient with obesity without metabolic alterations, similar to the phenotype described as metabolic healthy obesity.

Published: November 2018

AbstractThe mossy lithium dendrite growth during repeated lithium plating/stripping induces low Coulombic efficiency, poor lifespan, and safety concerns of working lithium metal batteries. Herein, atomically dispersed CoNx‐doped graphene is exploited as a host to accommodate dendrite‐free lithium deposits. The coordination between Co and N in the conductive matrix can effectively regulate the local electronic structure, and thereby enhance the adsorption of lithium ions and promote the following nucleation process. Meanwhile, the doped N facilitates high dispersion of Co atoms into graphene through the CoN coordination bond. The strong lithiophilicity provided by N coordinated with Co promises a uniform lithium nucleation behavior, further contributing to the smooth lithium deposition morphology. These characteristics afford a superhigh Coulombic efficiency of 99.2% at 2.0 mA cm−2 (≈400 cycles) and 5.0 mA cm−2 (350 cycles), and 98.2% at 10.0 mA cm−2 (200 cycles) with a capacity of 2.0 mAh cm−2. LiFePO4|CoNC–Li full cells deliver a long lifespan of 340 cycles at 1.0 C (240 cycles for routine cells). This offers fresh insights into effectively regulating the lithiophilic chemistry of lithium metal host toward uniform nucleation and growth of lithium deposits in working high‐energy‐density batteries.

Abstract4‐(Methylnitrosamino)‐1‐(3‐pyridyl)‐1‐butanol and cotinine are valuable biomarkers of tobacco smoke exposure. It is crucial to detect them for evaluating the health impact of exposure and the understanding of detoxification mechanism in humans. Considering the huge difference concentration in smoker's urine, they are always detected separately rather than simultaneously. In this work, we have developed an effective system of two‐dimensional liquid chromatography coupled with tandem mass spectrometry for high‐throughput simultaneous determination of 4‐(methylnitrosamino)‐1‐(3‐pyridyl)‐1‐butanol and cotinine in smoker's urine. The strong cation‐exchange and the reversed‐phase chromatography were chosen as the first and second dimensional studies. The orthogonality of this two‐dimensional system was evaluated through the separation of 4‐(methylnitrosamino)‐1‐(3‐pyridyl)‐1‐butanol and cotinine. Compared with traditional methodologies, the limits of detection of the method were 0.24 pg/mL and 0.054 ng/mL for 4‐(methylnitrosamino)‐1‐(3‐pyridyl)‐1‐butanol and cotinine respectively. The recoveries of the spiked samples were 99.8‐105.1 and 111.9‐114.2% for 4‐(methylnitrosamino)‐1‐(3‐pyridyl)‐1‐butanol and cotinine respectively in urine. The precisions of the method were 0.43‐3.07 and 0.73‐2.11%. The method is useful for monitoring 4‐(methylnitrosamino)‐1‐(3‐pyridyl)‐1‐butanol and cotinine in smoking and satisfying to evaluate the tobacco exposure.

AbstractLarge river deltas are complex ecosystems that are believed to play a pivotal role in promoting the early marine growth and survival of threatened Chinook Salmon Oncorhynchus tshawytscha. We used a fish bioenergetics model to assess the functional role of multiple delta habitats across a gradient of salinities and vegetation types, where consumption and growth rate potential (GRP) were considered as proxies for habitat quality. We subsequently compared our model output to empirical, or realized, growth estimates from scale circuli. In terms of consumption, prey energy density (EDprey) was 46–86% higher in tidal freshwater forest than in any other habitat type, while estimated consumption rates (expressed as proportion of maximum daily consumption; Pcmax) were positively correlated with FL. These size‐related differences in Pcmax led to a noticeable increase along a freshwater‐to‐saline gradient from roughly 0.25 in tidal freshwater forest to 0.55 in the offshore subtidal zone, yet despite higher observed Pcmax values in nearshore and offshore habitats, the tidal freshwater forest and emergent salt marsh demonstrated the highest modeled GRP values. Similarly, realized growth rates for fish caught in tidal freshwater forest were up to 0.5% higher per day than for fish caught in the offshore area, but habitat‐level differences were overshadowed by allometry and rearing origin. Scales from unmarked fish (assumed to be of wild origin) indicated that they grew, on average, 11% faster than did hatchery fish; however, these differences were subtle and were more obvious at fork lengths <100 mm. Our results suggest that tidal forests and emergent marshes may offer early life growth advantages for wild Chinook Salmon, but that wild and hatchery fish can compensate as they move seaward by opportunistically consuming greater quantities of low‐energy density prey, taking advantage of pulses of larval forage fish, or by spending time in multiple interconnected habitat types.
Blade imbalance fault diagnosis of doubly fed wind turbine based on current coordinate transformation
Authors: Yang Dong , Tang Ju , Zeng Fuping 
Published: November 2018

AbstractA stator current characteristic analysis method based on coordinate transformation is proposed to address the issue of the double‐fed induction generator (DFIG) blade imbalance. Based on the DFIG and the wind turbine transmission chain model, the stator current expression of DFIG under blade imbalance failure was derived in detail, and the corresponding fault characteristic frequency was analyzed, which shows that the blade imbalance fault causes the stator current of the DFIG to generate the fault feature component with frequency fm on the d‐axis and q‐axis components. Then, the stator current characteristic analysis method based on coordinate transformation was proposed. Finally, a simulation model of DFIG with blade imbalance was established, and the fault characteristics of the turbine under different wind speeds and imbalance coefficients are simulated and analyzed. The results show that the stator current characteristic analysis method based on coordinate transformation can extract the characteristics of imbalanced fault and can be effective in determining the severity of the fault by monitoring the changes in the amplitude of the characteristic frequency compared with direct spectrum analysis of stator current and blade speed. © 2018 Institute of Electrical Engineers of Japan.

ZusammenfassungIn naher Zukunft werden Roboter immer häufiger in den Lebensbereichen von Alltagsnutzerinnen und -nutzern anzutreffen sein. Sehr deutlich wird dies am Beispiel von Haushalts- und Pflegerobotern, denen im Hinblick auf eine alternde Gesellschaft verstärkt die Rolle des Mitbewohners und Weggefährten zukommen wird. Damit einher geht der Wunsch, die Mensch-Roboter-Kommunikation menschzentrierter zu gestalten. Es geht nicht mehr lediglich um die effiziente Durchführung von Aufgaben, sondern auch darum, für den Menschen ein angenehmes Interaktionserlebnis zu schaffen und ein Vertrauensverhältnis zu dem Roboter herzustellen. Der nachfolgende Artikel diskutiert den aktuellen Stand in Forschung und Entwicklung im Bereich sozial interagierender Roboter, die über multimodale soziale Hinweisreize mit pflegebedürftigen Menschen kommunizieren.
Pflegeroboter aus Sicht der Geriatrie
Authors: Gisinger Christoph 
Published: November 2018

ZusammenfassungIm Rahmen von zwei großen EU-Forschungsprojekten (HOBBIT und STRANDS) wurden Feldstudien über den Langzeiteinsatz von Robotersystemen in der geriatrischen Pflege- und Rehabilitationseinrichtung Haus der Barmherzigkeit und in Privatwohnungen von alleine lebenden Menschen im Alter über 75 Jahre durchgeführt. Die geriatrischen Patienten reagierten im Allgemeinen offen und aufgeschlossen, wesentlich zurückhaltender waren – vor allem anfangs – die Mitarbeiterinnen und Mitarbeiter. Die technischen Projektpartner bewerteten den Langzeiteinsatz unter Alltagsbedingungen äußerst positiv, weil die Assistenzrobotersysteme außerhalb des Labors unter Real-Life-Bedingungen überhaupt langfristig und weitgehend autonom funktionsfähig waren. Die Nutzer (Pflegepatienten, deren Angehörige und Mitarbeiter) reagierten eher enttäuscht, weil die eingesetzten Prototypen nicht ausreichend robust, rasch und verlässlich funktionierten und dadurch zu wenig Unterstützung im Alltag und praktischer Nutzen erlebbar war. Im weiteren Projektverlauf konnten Ängste der Mitarbeiter entkräftet werden, dass Pflegepersonen durch Roboter in absehbarer Zeit ersetzt werden könnten. Für Teilaufgaben oder unterstützend bzw. im Tandem wird jedoch ein großes Potenzial für intelligente technische Lösungen begrüßt. Seitens der Nutzer bzw. Pflegepatienten zeigte sich keine grundsätzliche Ablehnung von robust und sicher funktionierenden Robotern und sogar eine Präferenz für technische Hilfe statt Personenhilfe, wenn es um den Intimbereich (z. B. Körperpflege, Ausscheidung) geht und dadurch Autonomie und Selbstständigkeit erhalten werden können. Hier gibt es allerdings technische, wirtschaftliche, Sicherheits- und ethische Probleme, die noch gelöst werden müssen. „Pflegeroboter“ werden kommen, auch wenn noch ein langer Weg vor uns liegt und die genaue Funktionalität noch einer Klärung bedarf.
Planar two-loop five-parton amplitudes from numerical unitarity
Authors: Abreu S. , Febres Cordero F. , Ita H. , Page B. , Sotnikov V. 
Published: November 2018

AbstractWe compute a complete set of independent leading-color two-loop five-parton amplitudes in QCD. These constitute a fundamental ingredient for the next-to-next-to-leading order QCD corrections to three-jet production at hadron colliders. We show how to consistently consider helicity amplitudes with external fermions in dimensional regularization, allowing the application of a numerical variant of the unitarity method. Amplitudes are computed by exploiting a decomposition of the integrand into master and surface terms that is independent of the parton type. Master integral coefficients are numerically computed in either finite-field or floating-point arithmetic and combined with known analytic master integrals. We recompute leading-color two-loop four-parton amplitudes as a check of our implementation. Results are presented for all independent four- and five-parton processes including contributions with massless closed fermion loops.
14C Release from TRIGA irradiated graphite

Published: November 2018

ABSTRACTLeaching tests were carried out in aerobic and anaerobic conditions to assess the 14C released from TRIGA irradiated graphite. Both total 14C and inorganic and organic fractions in the leachant solutions were measured. The experimental results obtained from the leaching tests confirm the low 14C release rate in alkaline environment. Less than 2% of the total 14C inventory in the specimens subject to the leaching tests was released as dissolved species. Both inorganic and organic 14C species are released in alkaline conditions, with more inorganic 14C release under aerobic conditions (around 68% of the total 14C released was released as inorganic dissolved species), and more organic 14C species in anaerobic conditions (around 65% of the total 14C released was released as organic dissolved species). Both for anaerobic and aerobic conditions, the leaching rates are high in the first days of immersion and decrease after that, indicating a two stage process: an initial quick release (less than 9 × 10–02 % of inventory/day for the first 48 days) followed by a slower release rate (around 4 × 10–03 % of inventory/day).
