Published: February 2021

AbstractSubstitution of petroleum‐based processing oils with eco‐friendly sustainable plasticizers in rubber compounds has gained much global attention due to their toxicity. In this regard, so far, the major attempts have focused on substituting aromatic oils with fatty acid based vegetable oils. In this work, the chemical and physical effects of canola oil as a model of fatty acid based vegetable oils on the process‐ability, vulcanization kinetics, and final properties of carbon‐black filled styrene–butadiene rubbers are systematically investigated. In contrast to the previous studies, it was shown that although these types of vegetable oils have a plasticizing impact, they can indeed threaten the requirements of reinforcing criteria in rubber vulcanizates. The final properties of the vulcanizates were found to be deteriorated due to the incompatibility of canola oil fatty acids constituents with rubber matrix and especially as a result of chemical interference of their unsaturated bonds in sulfur vulcanization kinetics.

Abstract‘Yuetang 09‐13’ (‘YT 09‐13’) (Reg. no. CV‐197, PI 695070) sugarcane (a complex hybrid of Saccharum spp.) was selected and evaluated by the researchers of Institute of Bioengineering, Guangdong Academy of Sciences, from the progenies of a cross between YT 93‐159 (female) and ROC 22 (male). It was released to the growers in Guangdong Province, China, in July 2017. Yield data from three crop cycles (plant cane, first ratoon, and second ratoon) of 15 regional trials during 2015–2017 showed that the average cane yield of YT 09‐13 was 100.66 Mg ha−1, about 3.41% higher than that of ROC 22 (the check cultivar); the average sugar yield was 14.88 Mg ha−1, about 6.82% higher than that of ROC 22 (the check cultivar); and the average fiber content was 10.41%. YT 09‐13 is tolerant to drought and resistant to smut, Sugarcane mosaic virus, and brown rust diseases. YT 09‐13 is a suitable cultivar for planting and distributing in the main sugarcane areas of Hainan, Guangdong, Guangxi, and Yunnan.

Published: February 2021

AbstractObjectivesTo measure rates of detection via screening, perceived self‐imposed delays in seeking medical attention, and support seeking in a sample of regional and remote people with a cancer diagnosis and to test whether an association exists between these behaviours and minimising problems and resignation, a need for self‐control and reliance and fatalism. Correlations and binary logistic regressions were conducted to test the associations between demographic characteristics, attitudes and behaviours.ResultsFemales were more likely to have had their cancer detected via screening (OR = 10.02, CI = 3.49–28.78). Younger participants (r = −0.103, p = 0.009) were slightly more likely to seek at least one form of support and online support was sought more often by younger patients (r = −0.269, p < 0.001), females (r = 0.152, p < 0.001), those from higher socio‐economic (SES) areas (r = 0.100, p = 0.012), and those with higher education levels (r = 0.247, p < 0.001). Younger (r = −0.161, p < 0.001), and female (r = 0.82, p = 0.013), participants were also slightly more likely to seek support specifically through cancer support groups. No significant relationships between minimising problems and resignation, needs for control and self‐reliance or fatalism and detection via screening, support seeking, or perceived self‐imposed delays to seeking medical attention were apparent, with the exception that those with higher fatalism (predetermined health) were slightly less likely to report seeking support or information online (OR = 0.79, CI = 0.65–0.95) and slightly more likely to report using Cancer Council's support services (OR = 1.24, CI = 1.02–1.52).ConclusionsStrategies to improve the accessibility and appropriateness of support available for regional and remote cancer patients should consider interventions that remove barriers to access associated with age, gender, and education as opposed to those which address the attitudinal traits measured here.

AbstractAimThe purpose of this systematic review was to determine the effectiveness of self‐management interventions for older adults with cancer and to determine the effective components of said interventions.MethodsWe conducted a systematic review of self‐management interventions for older adults (65+) with cancer guided by the Preferred Reporting Items for Systematic Reviews and Meta‐Analysis statement. We conducted an exhaustive search of the following databases: Ageline, AMED, ASSIA, CINAHL, Cochrane, Embase, Medline, PsychINFO, and Sociological Abstracts. We assessed for quality using the Cochrane Risk of Bias tool and Down & Black for quasi‐experimental studies, with data synthesized in a narrative and tabular format.ResultsSixteen thousand nine hundred and eight‐five titles and abstracts were screened, subsequently 452 full‐text papers were reviewed by two independent reviewers, of which 13 full‐text papers were included in the final review. All self‐management interventions included in this review measured Quality of Life; other outcomes included mood, self‐care activity, supportive care needs, self‐advocacy, pain intensity, and analgesic intake; only one intervention measured frailty. Effective interventions were delivered by a multidisciplinary teams (n = 4), nurses (n = 3), and mental health professionals (n = 1). Self‐management core skills most commonly targeted included: problem solving; behavioural self‐monitoring and tailoring; and settings goals and action planning.ConclusionsGlobal calls to action argue for increased emphasize on self‐management but presently, few interventions exist that explicitly target the self‐management needs of older adults with cancer. Future work should focus on explicit pathways to support older adults and their caregivers to prepare for and engage in cancer self‐management processes and behaviours.
Hard silicon carbonitride thin‐film coatings by remote hydrogen plasma chemical vapor deposition using aminosilane and silazane precursors. 2: Physical, optical, and mechanical properties of deposited films
Authors: Wrobel Aleksander M. , Uznanski Pawel 
Published: February 2021

AbstractPhysical, optical, and mechanical properties of silicon carbonitride (a‐SiCN) films produced by remote hydrogen plasma chemical vapor deposition (RP‐CVD) using aminosilane and disilazane precursors are examined in relation to their chemical structure. The films deposited at different temperatures (30–400°C) were characterized in terms of their density, refractive index, optical bandgap, photoluminescence, adhesion to a substrate, hardness, elastic modulus resistance to wear (predicted from the “plasticity index” values), and friction coefficient. Reasonable structural dependencies of film properties were determined using the relative integrated intensities of the infrared absorption bands from the Si−N and Si−C bonds, and the X‐ray photoelectron spectroscopy Si2p band from the Si−C bonds (controlled by substrate temperature) evaluated in the first part of this study. In view of their good mechanical properties, a‐SiCN films seem to be useful coatings for improving surface mechanics of engineering materials for advanced technology.

Authors: Agnihotri Ruchika , Oommen Charlie 
Published: February 2021

AbstractAqueous solution of Hydroxylammonium nitrate (HAN) in combination with a suitable fuel has been explored as a promising high performing green monopropellant in recent times. The current study primarily explores the effect of the addition of a fuel component into HAN solution on the sustainability of a recently developed catalyst which was examined for the only binary system consisting of HAN and water. The HAN ternary system examined was HAN: methanol: water in 70 : 15 : 15 (w/w) composition. The endurance of an ‘iridium over alumina’ catalyst and an indigenously developed cobalt doped ceria‐based catalyst was analysed using a batch reactor wherein a pressure rise during decomposition of propellant whilst a pulse mode operation was monitored. Catalysts were also characterized via SEM/EDS, XRD, and XPS to identify changes over the period of sequential injection in the batch reactor. Doped ceria catalyst was found to be far robust and resistant to any poisoning when compared to iridium catalyst at run time of the operation involving nearly 45 sequential injections of propellant over the catalyst.
Thermal Behavior and Micro Structure of TKX‐50
Authors: Herrmann Michael , Förter‐Barth Ulrich 
Published: February 2021

AbstractThe thermal behaviour of TKX‐50 was reinvestigated in an extended temperature range by means of temperature resolved X‐ray diffraction. TKX‐50, synthesized at the Fraunhofer ICT, was identified using Rietveld‐analysis and reference data from the CCDC. Monitoring the refined crystal data versus temperature verified a highly anisotropic expansion behavior connected to a layer structure. However, the coefficients of thermal expansion (CTEs) were found at an order of magnitude higher than reported, and a slight bent of lattice parameter a was found near room temperature. At temperatures between 180 and 200 °C the decomposition of TKX‐50 started with the formation of 1 to 5 wt.% diammonium 5,5’‐bistetrazole‐1,1’‐diolate (ABTOX). Moreover, the micro structure was investigated by means of size/strain analysis and so called indexed Williamson‐Hall plot. The analysis revealed moderate micro strain and absence of size broadening. The results give rise to the hypothesis that the (010) layer structure supports a low sensitivity of TKX‐50 without impairment of the mechanical stability. The results provide a base for future quality assessment and the development of advanced products.
Combination of deep neural network with attention mechanism enhances the explainability of protein contact prediction
Authors: Chen Chen , Wu Tianqi , Guo Zhiye , Cheng Jianlin 
Published: February 2021

AbstractDeep learning has emerged as a revolutionary technology for protein residue‐residue contact prediction since the 2012 CASP10 competition. Considerable advancements in the predictive power of the deep learning‐based contact predictions have been achieved since then. However, little effort has been put into interpreting the black‐box deep learning methods. Algorithms that can interpret the relationship between predicted contact maps and the internal mechanism of the deep learning architectures are needed to explore the essential components of contact inference and improve their explainability. In this study, we present an attention‐based convolutional neural network for protein contact prediction, which consists of two attention mechanism‐based modules: sequence attention and regional attention. Our benchmark results on the CASP13 free‐modeling targets demonstrate that the two attention modules added on top of existing typical deep learning models exhibit a complementary effect that contributes to prediction improvements. More importantly, the inclusion of the attention mechanism provides interpretable patterns that contain useful insights into the key fold‐determining residues in proteins. We expect the attention‐based model can provide a reliable and practically interpretable technique that helps break the current bottlenecks in explaining deep neural networks for contact prediction.

AbstractBACKGROUNDDiapause plays a vital role in the survival and population reproduction of the migratory locust in temperate regions. Although some studies have suggested that photoperiod and temperature are two important environmental factors involved in the induction and termination of embryonic diapause in locusts, the independent or synergetic roles of these two factors are still unclear.RESULTSWe designed crossover experiments to investigate the effects of photoperiod, temperature and treatment time on the induction and termination of embryonic diapause in locusts by optical coherence tomography (OCT), which can track the entire embryonic developmental processvianoninvasive 3D real‐time imaging. Diapause induction experiments showed that a short photoperiod (in adults) and a low egg treatment temperature are the most important prerequisites for inducing egg diapause. The diapause rate reached 90.7% when the adults were reared under a short photoperiod (8 L:16 D) and the eggs were treated at 22 °C. However, the adult rearing temperature had no significant effect on diapause induction. Analysis of variance also confirmed that there was a significant interactive effect between parental photoperiod and egg treatment temperature. Moreover, diapause termination experiments showed that 13 °C (near the developmental threshold temperature of 15 °C) for 20 days is the most effective condition for terminating diapause.CONCLUSIONOur study provides accurate photoperiod and temperature thresholds for inducing and terminating diapause in the migratory locust, suggesting potential applications in the prediction and control of locust plagues.© 2021 Society of Chemical Industry
For better or for worse mental health? The role of family networks in exogamous unions
Authors: Eibich Peter , Liu Chia 
Published: February 2021

AbstractThis study tests whether being in an exogamous union affects older individual's family networks, and whether associations between exogamy and mental health reported in previous studies operate through changes in family ties and differ by gender. We focus on individuals aged 60 or above in the German Socio‐Economic Panel Study between 2002 and 2016. We describe demographic and family characteristics of individuals in different types of union and estimate correlated random effects models on the changes of mental health. Exogamous immigrants have larger family networks than endogamous immigrants due to a higher chance of having in‐laws nearby, while exogamous natives have smaller family networks than their endogamous counterparts. Native women in a union with immigrants exhibit worse mental health than endogamous native women, and the same disadvantage is held by immigrant men partnered with native women. Family networks influence mental health but contribute little to observed differences.
Sulfur impurity level in the O‐rich ZnSxO1−x alloy obtained by first principle calculations

Published: February 2021

AbstractThe LDA + U method is employed to study the electronic properties of ZnSxO1−x (0 ≤ x ≤ 0.25). The calculated results are consistent with the experimental results. It is found that the substitution of oxygen atoms by sulfur atoms can bring a localized sulfur defect level into ZnO. The sulfur level appears at 0.398 eV above the Γ VBM of ZnO. It is also found that the strongly localized effect of the sulfur level in the composition range (0 < x ≤ 0.1875) can pin the Γ VBM of ZnSxO1−x in the vicinity of the initial sulfur level. If the sulfur fraction goes on increasing, the sharp peak of the S‐3p states cannot be observed, demonstrating that the localized effect weakens.

Published: February 2021

RationaleWhile high‐throughput proteomic methods have been widely applied to monoclonal antibodies and human immunoglobulin gamma (IgG) samples, less information is available on porcine IgG. As pigs are considered one of the most suitable species for xenotransplantation, it is important to characterize IgG amino acid sequences and glycosylation profiles, which is the focus of this study.MethodsThree different purified porcine IgG samples, including wild‐type and knockout species, were digested with trypsin and enriched for glycopeptides. Digestion mixtures were spiked with a mixture of six standard peptides. Analysis was performed using electrospray ionization liquid chromatography–tandem mass spectrometry (MS/MS) in standard MS/MS data‐dependent acquisition mode on a hybrid triple quadrupole time‐of‐flight mass spectrometer.ResultsTo facilitate the classification of subtypes detected experimentally, UniprotKB database entries were organized using comparative alignment scores. Sequences were grouped based on 11 different subtypes as translated from GenBank entries. Proteomic searches were accomplished automatically using specialized software, whereas glycoprotein searches were performed manually by monitoring the extracted chromatograms of diagnostic MS/MS glycan fragments and studying their corresponding mass spectra; 40–50 non‐glycosylated peptides and 4–5 glycosylated peptides were detected in each sample, with several glycoforms per sequence.ConclusionsProteomic analysis of porcine IgG is complicated by factors such as the presence of several subtypes, redundant heavy chain (HC) sequences in protein databases, and the lack of consistent cross‐referencing between databases. Aligning and comparing HC sequences were necessary to eliminate redundancy. This study highlights the complexity of pig IgG and shows the importance of MS in proteomics and glycoproteomics.

AbstractBackgroundThis study is an initial comparative analysis of perioperative and intermediate‐term functional outcomes between patients who underwent robot‐assisted laparoscopic (RALS) or conventional laparoscopic surgery (LS).Materials and MethodsA total of 25 patients who underwent ileal ureter replacement (10 RALS and 15 LS) were followed by functional cine magnetic resonance urography (MRU) combined with a modified Whitaker test. Also, the characteristics, perioperative data and functional outcomes of the patients were compared.ResultsThe estimated blood loss, postoperative hospital stay and time to oral intake were significantly lower in the RALS group. At the median 14‐month follow‐up, all the patients showed improved renal function and were symptom‐free, with no signs of leakage or stenosis observed by cine MRU combined with a modified Whitaker test.ConclusionsRALS with an extracorporeal bowel resection is feasible and appears to be safe, with quick postoperative recovery and encouraging outcomes.

AbstractThis article is concerned with the tracking control problem of quadrotor unmanned aerial vehicle (UAV) with external disturbance. The aim of this article is to develop a robust control algorithm based on super‐twisting algorithm and adaptive dynamic programming (ADP), which drives the tracking errors of quadrotor UAV to zero. First, the adaptive terminal sliding mode disturbance observer is developed for estimating the external disturbance with unknown upper bound. Second, based on the estimation of disturbance, the super‐twisting compensation controller is constructed to eliminate the effect of the disturbance estimation error and obtain the nominal error dynamics. Then, nominal controller via ADP method is used to force the states of nominal system convergence to zero. Finally, the efficiency of the proposed method is illustrated by numerical simulations and experimental verification.

Published: February 2021

AbstractFloodplains are simultaneously the most productive and threatened ecosystems in the world, with land cover integrity compromised even in “protected” floodplains. Due to their rich biodiversity, monitoring of land cover and understanding the causative drivers becomes imperative in the protected floodplains. This work performs spatio‐temporal assessment of land cover changes and discovers the underlying processes in the largest protected floodplain of the Brahmaputra River (BR)—Kaziranga National Park (KNP). Remotely sensed images of 1988, 1998, 2008, and 2018 were analyzed using visual interpretation techniques coupled with class description keys in GIS platform along with ground‐based surveys. Results show a substantial area decline under Dense Forest (7.7%), Open Forest (10%), Waterlogged wetland (31.3%), and Marsh/Swamp (70.4%) land cover classes between 1988 and 2018. The considerable reduction in forests and wetlands is likely to impact the life support system of the park as they form the key habitats and food resources. Concurrently, dramatic area increase under riverine classes has led to huge landmass loss along the northern and eastern stretch. Though the BR and the local flood pulse are essential source of nutrient replenishment in the park, they also act as primary drivers of land cover alteration. Hydro‐geomorphic processes like bank erosion, high‐flood events, and siltation in association with vegetation succession and invasive species control the inter‐conversion of land cover classes in the KNP. The findings of this work provide an insight into the natural factors that instigate the land cover modification on large floodplains in general, and particularly in KNP.
