Published: January 2020

AbstractObtaining growth and physiologic data in the postnatal laboratory animal is common. However, monitoring growth in utero is far more difficult, with little data available except upon termination of pregnancy. High‐resolution ultrasound was used to monitor growth, morphology, and fetal well‐being in normotensive and hypertensive rabbits (21 fetuses) at day 16, 20, and 26 of the 32 day gestational period. Set protocols, comparable to those routinely assessed in humans, were devised and followed for each examination. Birth weight was greater in offspring of hypertensive as compared to normotensive mothers (p < 0.001); however, litter size was reduced. The greater birth weight was reflected in growth parameters measured throughout gestation indicating the predictive value of ultrasound. High‐resolution ultrasound was a reliable and sensitive method for biometric and morphologic assessment of the fetal rabbit, demonstrating that growth trajectory of offspring of hypertensive mothers may be altered early in gestation.

Child abuse is a global public health issue; however, there is a severe lack of reliable epidemiological data. This study estimates the period prevalence of child physical abuse requiring hospitalisation and the corresponding in‐hospital mortality, using the French medico‐administrative database. We included all children less than one year old who were hospitalised from 2007 to 2014. Three groups were defined: group one – physically abused children; group two – possible physically abused children; and group three – all other hospitalised children. Estimation of the national eight‐year period prevalence of physical abuse among hospitalised children was equivalent to the number of children included in group one or groups one and two divided by the number of children aged less than one year in France from 2007 to 2014. Infants hospitalised for physical abuse represent between 0.04 per cent (group 1) and 0.10 per cent (groups 1 and 2) of all children less than one year old in France, which corresponds to 0.28 per cent (group 1) and 0.74 per cent (groups 1 and 2) of all hospitalised children (less than one year old). Hospital mortality at first admission ranged from 2.93 per cent (group 1) to 2.36 per cent (groups 1 and 2). To our knowledge, this is the first study to provide an estimation of the period prevalence of child physical abuse requiring hospitalisation in France and the corresponding in‐hospital mortality. More effective prevention strategies are needed to help health professionals identify and protect at‐risk children. © 2019 John Wiley & Sons, Ltd.Key Practitioner Messages

The average hospital stay for physically abused children was much longer than for other children.
The in‐hospital mortality rate is higher for physically abused children than for those with other trauma‐related cases.
Identifying and coding child abuse accurately is an important step towards understanding the extent of this public health problem.

AbstractObjectivesWe sought to describe the outcomes of BVS use from a single‐center experience in which scaffold implantation was guided by intravascular imaging (ultrasound and/or optical coherence tomography) to identify and treat mechanical factors potentially related to BVS failure.BackgroundThe Absorb bioresorbable vascular scaffold (BVS) has been associated with an unexpectedly high incidence of thrombosis.MethodsBetween 11/2014 and 10/2016, 100 patients were treated with BVS. Intravascular imaging assessment before and after BVS implantation was performed in all cases.ResultsMean age was 58.1 years; 88% were male, 31% had diabetes, and 28% presented with acute coronary syndromes. A total of 171 lesions in 141 vessels were treated with 190 BVS (mean 1.9 scaffolds/patient). Further intervention following intravascular imaging to optimize BVS implantation was required in 31% of patients. Procedure success was 100%. All patients completed a 1‐year follow‐up. The 1‐year rate of target lesion failure was 4%, and there were no cases (0%) of scaffold thrombosis, myocardial infarction, or death.ConclusionsIn this real‐world experience, the use of intravascular imaging to guide BVS implantation was associated with a high 1‐year event‐free survival rate, with no scaffold thrombosis.

AbstractBackgroundIncidence of coronary access (CA) after transcatheter aortic valve replacement (TAVR) at long‐term follow‐up remains unknown. CA and percutaneous coronary intervention (PCI) after TAVR might present technical challenges, particularly with supra‐annular devices.MethodsPatients undergoing CA after being treated with TAVR at our institution were included in the study. Coronary interventions for coronary obstruction during TAVR procedure were excluded. Incidence, feasibility and outcomes of CA after TAVR were analyzed.ResultsOut of 912 patients aged 80 ± 7 years treated with TAVR at our institution between 2007 and 2018, 48 (5.3%) underwent CA at a median follow up of 769 [363–1,471] days. Twenty‐one had received a SAPIEN XT, 15 a SAPIEN 3, 6 Corevalve, 2 Evolut Pro, 2 JenaValve, and 2 Lotus valve. PCI was indicated in 26 (54%) cases. Seventeen (35%) procedures were performed for acute coronary syndromes (ACS). Independent predictors of CA after TAVR were younger age, previous PCI, and CABG. CA of both vessels was feasible in all patients with an intra‐annular device, while the right coronary artery was not engaged in two patients with a supra‐annular valve. PCI was successful in all but one case. All‐cause mortality was similar between patients needing CA for ACS and those who had other clinical indications.ConclusionsIn this high‐risk AS population, incidence of CA after TAVR at long‐term follow‐up was rather low. CA and PCI were safe and successful in most cases, with a lower rate of selective CA for supra‐annular devices.

AbstractConstructing electrode materials with high energy densities are the effective way to develop asymmetric supercapacitor devices. Therefore, the inlay of conductive materials into pseudocapacitive constituents is a practical approach to increase the performance of supercapacitor electrodes. Herein, we declare a facile one‐step as an economic strategy for tailoring carbon spheres (CSs) impregnated by CoFe2O4 to form a CoFe2O4@CSs composite. The CoFe2O4@CSs composite was fully characterized by X‐ray diffraction (XRD), Raman spectroscopy, X‐ray photoelectron spectroscopy (XPS), and transmission electron microscopy (TEM), which evidenced that CoFe2O4 nanoparticles were densely cored inside the carbon spheres. Moreover, the electrochemical characterization of the CoFe2O4@CSs composite was manifested high specific capacitance of (600 F/g) at a current density (1 A/g), high performance rate, and cycling stability. CoFe2O4@CSs has achieved capacitance retention of 94.1 % after 5000 charge/discharge cycles at a current density of 20 mA/g. The device‐based asymmetric supercapacitors were found to improve the energy density to 27.08 Wh/kg at a power density of 750 W/kg with 99 % capacitance retention, which is higher than the values previously reported. The exceptional performance of CoFe2O4@CSs composites gives high priority for such materials in variant electrochemical fields, owing to the harmony between CoFe2O4 nanoparticles and carbon spheres.

Published: January 2020

AbstractA modulated synthesis approach based on the chelating properties of oxalic acid (H2C2O4) is presented as a robust and versatile method to achieve highly crystalline Al‐based metal‐organic frameworks. A comparative study on this method and the already established modulation by hydrofluoric acid was conducted using MIL‐53 as test system. The superior performance of oxalic acid modulation in terms of crystallinity and absence of undesired impurities is explained by assessing the coordination modes of the two modulators and the structural features of the product. The validity of our approach was confirmed for a diverse set of Al‐MOFs, namely X‐MIL‐53 (X=OH, CH3O, Br, NO2), CAU‐10, MIL‐69, and Al(OH)ndc (ndc=1,4‐naphtalenedicarboxylate), highlighting the potential benefits of extending the use of this modulator to other coordination materials.

AbstractObjectivesPeripheral blood monocytes are categorized as classical (CD14++/CD16−) or nonclassical (CD14−/CD16+ and CD14+/CD16+) based on their CD14 expression and CD16 expression. Maturation of classical monocytes produces CD14+/CD16+ macrophages. Our aim was to clarify the in vivo distribution of CD14 and C16 monocytes/macrophages in three granulomatous skin diseases—sarcoidosis, granuloma annulare, and lupus miliaris disseminatus faciei.MethodsCD14 and CD16 immunohistochemistry, and CD14/CD16, CD16/CD11c, CD16/CD68, and CD16/factor XIIIa dual labeling were performed in tissues sampled from three cases of sarcoidosis, four cases of granuloma annulare, and three cases of lupus miliaris disseminatus faciei.ResultsThe main infiltrating cell types were CD14+/CD16+ and CD14−/CD16++ macrophages. A small number of CD14+/CD16− macrophages localized along the granuloma periphery. Dual immunofluorescence showed that CD16+ overlapped the most with CD68+ cells, partially overlapped with CD11c+ cells, and did not overlap with FXIIIa+ cells.ConclusionsInflammatory granulomatous skin diseases are characterized by CD16+, mature and inflammatory macrophages; some of which are in the process of maturation.

BackgroundCombined image‐guided fine‐needle aspiration biopsy (FNA) and core needle biopsy (CNB) has become the standard of care for diagnosis and/or molecular testing for patients with a solitary lung nodule at our institution. Our purpose was to evaluate the efficacy of this practice.MethodsWe identified patients who underwent combined lung FNA/CNB during 2012 at our institution. A total of 667 patients who underwent 682 combined lung FNA/CNB procedures were included in the study, including 355 men and 312 women. Combined lung FNA/CNB procedures were performed by a radiologist. The adequacy of FNA specimens was assessed immediately by a cytopathologist. The FNA and CNB specimens were interpreted separately by a cytopathologist and a surgical pathologist, respectively. The diagnostic accuracy of the combined technique was determined.ResultsThe rate of diagnostic consistency between FNA and CNB was 83.4%, and the rate of diagnostic accuracy for malignancy was 98.5% for combined FNA/CNB. Combined FNA/CNB showed a high diagnostic efficacy for malignancy (sensitivity, 97.6%; specificity, 100%). Combined FNA/CNB had a lower false‐negative rate for malignancy (2.2%) than either FNA (7.2%) or CNB (6.2%) alone. FNA contributed to 10.3% of molecular analyses as a complementary tissue source.ConclusionsCombined lung FNA/CNB has high diagnostic efficacy for malignancy and a lower false‐negative rate than either procedure alone. FNA was a valuable complement to CNB for molecular testing, potentially reducing patient inconvenience and morbidity associated with repeated lung needle biopsy.
Fabrication of a Biocompatible Mica/Gold Surface for Tip‐Enhanced Raman Spectroscopy

Published: January 2020

AbstractTip‐enhanced Raman spectroscopy (TERS) is a promising technique for structural studies of biological systems and biomolecules, owing to its ability to provide a chemical fingerprint with sub‐diffraction‐limit spatial resolution. This application of TERS has thus far been limited, due to difficulties in generating high field enhancements while maintaining biocompatibility. The high sensitivity achievable through TERS arises from the excitation of a localized surface plasmon resonance in a noble metal atomic force microscope (AFM) tip, which in combination with a metallic surface can produce huge enhancements in the local optical field. However, metals have poor biocompatibility, potentially introducing difficulties in characterizing native structure and conformation in biomolecules, whereas biocompatible surfaces have weak optical field enhancements. Herein, a novel, biocompatible, highly enhancing surface is designed and fabricated based on few‐monolayer mica flakes, mechanically exfoliated on a metal surface. These surfaces allow the formation of coupled plasmon enhancements for TERS imaging, while maintaining the biocompatibility and atomic flatness of the mica surface for high resolution AFM. The capability of these substrates for TERS is confirmed numerically and experimentally. We demonstrate up to five orders of magnitude improvement in TERS signals over conventional mica surfaces, expanding the sensitivity of TERS to a wide range of non‐resonant biomolecules with weak Raman cross‐sections. The increase in sensitivity obtained through this approach also enables the collection of nanoscale spectra with short integration times, improving hyperspectral mapping for these applications. These mica/metal surfaces therefore have the potential to revolutionize spectromicroscopy of complex, heterogeneous biological systems such as DNA and protein complexes.

AbstractPlanting date (PD) can significantly affect corn (Zea mays L.) yield. Our objective was to investigate the effects of hybrid and PD later than traditional time on irrigated corn performance in the Texas High Plains. A 2‐yr field study was conducted using four (2013) to six (2014) hybrids and four PDs (mid‐May [PD1], late May–early June [PD2], mid‐June [PD3], and late June–early July [PD4]). In PD1 and PD2, long‐season hybrids had greater yields (12–15 Mg ha−1) than short‐season hybrids (9–13 Mg ha−1). In PD4, short‐season hybrids (8–11 Mg ha−1) had yield advantage over long‐season hybrids (4–10 Mg ha−1). Low yield at late planting was related to reduced biomass, harvest index, kernel weight, and kernel number. Seasonal evapotranspiration (ET) was only reported in 2013. The average ET over PDs was 767 mm in a long‐season hybrid and 718 mm in a short‐season hybrid. Late planting resulted in lower ET (600 mm in PD4 vs. 822 mm in PD1). Hybrid and PD did not affect water use efficiency (WUE) except for 33D53AM, which had low WUE in PD4 due to low yield with late planting of this long‐season hybrid. This study demonstrated that high yield (∼15 Mg ha−1) and WUE (∼1.5 kg m−3) can be achieved with long‐season hybrids when planted before mid‐June, but short‐season hybrids were a better choice after mid‐June. With water limitations, further study is warranted on planting short‐season hybrids after mid‐June to reduce water use and irrigation.

AbstractDuring conventional fertilization, N is applied before or during the early growth stages of rice (Oryza sativa L.), usually resulting in N loss and waste. Therefore, developing effective N management practices to reduce N losses and increase rice yield and N use efficiency (NUE) will be beneficial to farmers and the environment. Here, the effects of delayed timing and reduced N fertilizer on the yield and NUE of japonica rice grown in Shenyang, China, were investigated in 2016 and 2017. Fertilization during the early tillering stage had no significant effect on the leaf area index (LAI), amount of bleeding sap, dry matter accumulation, or N accumulation by the mid‐tillering (nine‐leaf) stage. After the jointing stage, compared with conventional N treatment, delayed timing of tillering fertilization from 5.5‐leaf stage (7 d after transplanting) to the nine‐leaf stage increased root activity and enhanced nitrate reductase and glutamine synthetase activities in rice leaves. Greater N accumulation from the jointing to grain‐filling stages increased LAI and dry matter accumulation. Average grain yield as a result of delayed N fertilization was 8.6 and 30.7% higher than conventional N treatment. Given the results, optimizing N application rates and timing improved NUE and decreased the amount of N fertilizer needed for maintaining and increasing yield. Collectively, these results indicate that the delayed timing of tillering N fertilizer improves rice yield and NUE.
Sugarcane and sugar yields in Louisiana (1911–2018): Varietal development and mechanization
Authors: Schmitz Andrew , Kennedy P. Lynn , Zhang Fangyi 
Published: January 2020

AbstractLouisiana is the second largest producer of sugarcane (Saccharum officinarum L.) in the United States. New sugarcane cultivars better adapted for Louisiana have been in development since the inception of a three‐way cooperative breeding program in the 1920s. Piecewise regression is used to determine the growth in both Louisiana sugarcane and sugar yields and how new sugarcane cultivars and mechanization have had a positive impact of yields. The analysis uses several breakpoints for periods between 1911 and 2018 to consider the impact of varietal development and mechanization. In most cases, new sugarcane cultivars and changes in mechanization in Louisiana have significantly increased the yield of sugarcane and sugar. From 1911 to 2018, raw sugar yield increased at an annual rate of 0.061 t ha−1, while gross sugarcane yield increased by 0.47 t ha−1. Prior to 1927, yield growth was either negative or highly variable; since 1927, yield growth for both raw sugar and gross sugarcane have been positive and significant.
Load characterization and power conditioner synthesis using higher‐order elements
Authors: Jeltsema Dimitri 
Published: January 2020

SummaryIt is shown that virtually all nonlinear and/or time‐varying loads that generate harmonic current distortion can be characterized in terms of so‐called higher‐order circuit elements. The most relevant higher‐order elements exploited in this paper are the memristor, meminductor, and memcapacitor. Such elements naturally arise by introducing constitutive relationships in terms of higher‐order voltage and current differentials and integrals. Consequently, the power conditioner necessary to compensate for the load current distortions is synthesized similarly. The new characterization and compensation synthesis is applied to the half‐wave rectifier and the controlled bridge converter.

Published: January 2020

SummaryCloud computing has been gaining widespread significance in recent times, especially with the advent of state‐of‐the‐art communication technologies and data‐handling systems. Large volumes of data are being handled in real time and their availability is made feasible to consumers in an efficient manner through cloud computing networks. However, security of such data being transferred through clouds characterized in a centralized configuration is of prime concern, which has been investigated in this research paper. Secured transmission of data through a secured key transmission using appropriate authentication mechanism has been the driving force behind the research carried out in this paper. In order to resolve the existing issues in clouds in terms of computational as well as storage complexities, a secure key transmission Rivest‐Shamir‐Adleman (SKT‐RSA) protocol is proposed based on the secure key transmission. Key distribution between the certified authority and the end user is proposed. The proposed protocol is a tree‐based cluster key distribution scheme.

Published: January 2020

AbstractShale gas as green and clean energy is attracting more interest. However, shale hydration and swelling have become the major challenges using water‐based drilling fluids, replacing oil‐based drilling fluids, for developing shale gas. In this work, a low molecular weight branched polyamine (NETS) as clay swelling inhibitor was synthesized. The NETS performed excellent inhibition property by linear expansion experiments and cuttings hot‐rolling recovery. The inhibition mechanism of NETS was investigated using X‐ray diffraction, fourier transform infrared spectroscopy, cation exchange capacity, X‐ray photoelectron spectroscopy, scanning electron microscopy, and zeta potential. The results show that the NETS can adsorb on Na‐Mt, decrease the basal spacing of wet Na‐Mt from 1.91 to 1.43 nm, and replace majority sodium ions from interlayer of Na‐Mt. However, replaceability of sodium ions and inhibition of water molecules of ethylenediamine are worse than NETS. These indicate that the primary amines of NETS had strong interaction with Na‐Mt, tensed clay layers and decrease the basal spacing. The combination of long hydrophobic chain and primary amines makes NETS to adsorb on surface of Na‐Mt, intercalate into interlayer of Na‐Mt with tilted monolayer arrangement, and replace sodium ions. The more the number of primary amine groups, the better the inhibition performance. Therefore, NETS has a great potential to be an outstanding shale inhibitor of water‐based drilling fluids in the future.
