Authors: Dong Shichang , Song Hao , Song Caiyun 
Published: October 2021

Based on wheel-rail impact vibration and considering the body stiffness and natural damping, this paper builds a four-degree-of-freedom vibro-impact system model for passenger train’s vertical vibration reduction system. The Poincaré map of the system is determined by the analytic solution of the system derived from the motion differential equation of the multi-degree-of-freedom vibro-impact system combined with Newton's second law. It is found that the fork bifurcation, Hopf bifurcation and other dynamical behavior leading to Chaos when the system parameters are changed. On this basis, the dynamic parameters of the train are optimized to avoid chaos in the train operation, reduce the vertical vibration of the train, improve the stability and comfort of the train operation, and provide the theoretical basis for the active vibration reduction design of the train.

Published: October 2021

Engineering machines and components are proneto structural failures during their service time due to certaintechnical reasons and also due to some unforeseencircumstances. The technical breakdowns sometime lead tohigh economic imbalance and can also be fatal to life andproperty. Predicting the failure and evaluating the breakagecharacteristics of engineering components are crucial indetermining the life of the component and also increasetheir maintenance and safety in daily life. This research study deals with the modelling andnumerical simulations of an aluminium alloy specimen in3D stress-state and thereby predicting the fatigue failure ofthe material subjected to external cyclic loadings. Topredict the failure of a component, a specimen with aninduced crack can be evaluated through cyclic loadingprocess. It is based on the fact that the presence of a crackstends to modify the stresses present locally on thecomponent that the elastic deformation and the stressesattributed with them are totally insufficient for the designagainst fracture. It is based on the assumption that thespecimen undergoes complete fracture when the crackreaches its critical size even though the stress at the criticalcrack tip is much lower than the yield stress of thecomponent. The critical size of the crack is based on theapplication of the load and the number of load cycles itundergoes.The main aim of this research is to present andvalidate the numerical method for the study of theinfluence of cracks present in the engineering components.Finite element method was applied for numericalsimulation. In this study the tension, torsion, combined
tension-torsion and fatigue loads was applied. Theexperimental testing data of mechanical properties wasused in numerical simulation as input data. This researchstudy investigates the three-dimensional stress-strain stateand fatigue prediction of D16T aluminium alloy which ispredominantly used in the aerospace and automobileindustries for their high strength-to-weight ratio and muchbetter physical properties. The different specimen modelsare then analysed and the most efficient one was selectedfor the preliminary experimental tests.
Impacts of climate change on water resources in the major countries along the Belt and Road
Authors: Du Panpan , Xu Ming , Li Renqiang 
Published: October 2021

Background
Climate change has altered global hydrological cycles mainly due to changes in temperature and precipitation, which may exacerbate the global and regional water shortage issues, especially in the countries along the Belt and Road (B&R).

Methods
In this paper, we assessed water supply, demand, and stress under three climate change scenarios in the major countries along the Belt and Road. We ensembled ten Global Climate Model (GCM) runoff data and downscaled it to a finer resolution of 0.1° × 0.1° by the random forest model.

Results
Our results showed that the GCM runoff was highly correlated with the FAO renewable water resources and thus could be used to estimate water supply. Climate change would increase water supply by 4.85%, 5.18%, 8.16% and water demand by 1.45%, 1.68%, 2.36% under RCP 2.6, 4.5, and 8.5 scenarios by 2050s, respectively. As a result, climate change will, in general, have little impact on water stress in the B&R countries as a whole. However, climate change will make future water resources more unevenly distributed among the B&R countries and regions, exacerbating water stress in some countries, especially in Central Asia and West Asia. Our results are informative for water resource managers and policymakers in the B&R countries to make sustainable water management strategies under future climate change.

AbstractThere has been growing research interest in hydrogen bonded organic frameworks (HOFs) by virtue of their great structural crystallinity, large surface areas and porosity. Their potential in electrochemical applications, unfortunately, remains elusive because weak hydrogen bonds would dissociate in solution that eventually compromises the structural integrity. Herein, it is demonstrated that this issue may be overcome by designing and introducing multisite hydrogen bonding within HOFs. 2D molecular sheets are prepared using diaminotriazole as the linkers for the first time. In spite of the molecular thickness (≈1 nm), they are chemically stable and mechanically robust, and have diminished solubility in most polar or nonpolar organic solvents. This solution‐stable HOF exhibits an excellent electrochemical performance for Na+ ion storage. In particular, it enables an exceptional cycle life of >10 000 cycles at 1 A g‐1, which is far superior to most other organic electrode materials. Theoretical simulations indicate that the activation barrier for the intralayer or interlayer diffusion of Na+ ions within the organic frameworks is small.

Published: October 2021

AbstractPremiseThe genusGynoxysand relatives form a species‐rich lineage of Andean shrubs and trees with low genetic distances within the sunflower subtribe Tussilaginineae. Previous molecular phylogenetic investigations of the Tussilaginineae have included few, if any, representatives of this Gynoxoid group or reconstructed ambiguous patterns of relationships for it.MethodsWe sequenced complete plastid genomes of 21 species of the Gynoxoid group and related Tussilaginineae and conducted detailed comparisons of the phylogenetic relationships supported by the gene, intron, and intergenic spacer partitions of these genomes. We also evaluated the impact of manual, motif‐based adjustments of automatic DNA sequence alignments on phylogenetic tree inference.ResultsOur results indicate that the inclusion of all plastid genome partitions is needed to infer well‐supported phylogenetic trees of the Gynoxoid group. Whole plastome‐based tree inference suggests that the generaGynoxysandNordenstamiaare polyphyletic and form the core clade of the Gynoxoid group. This clade is sister to a clade ofAequatoriumandParagynoxysand also includes some but not all representatives ofParacalia.ConclusionsThe concatenation and combined analysis of all plastid genome partitions and the construction of manually‐curated, motif‐based DNA sequence alignments are found to be instrumental in the recovery of well‐supported relationships of the Gynoxoid group. We demonstrate that the correct assessment of homology in genome‐level plastid sequence data sets is crucial for subsequent phylogeny reconstruction and that the manual post‐processing of multiple sequence alignments improves the reliability of such reconstructions amid low genetic distances between taxa.

AbstractThis study investigates if genetic factors could contribute to the high rate of mood disorders reported in a U.S. community known to have a restricted early founder population (confirmed here through runs of homozygosity analysis). Polygenic scores (PGSs) for eight common diseases, disorders, or traits, including psychiatric disorders, were calculated in 274 participants (125 mood disorder cases) who each reported three or four grandparents born in the community. Ancestry‐matched controls were selected from the UK Biobank (UKB; three sets of N = 1,822 each). The mean PGSs were significantly higher in the community for major depression PRS (p = 2.1 × 10−19, 0.56 SD units), bipolar disorder (p = 2.5 × 10−15, 0.56 SD units), and schizophrenia (p = 3.8 × 10−21, 0.64 SD units). The PGSs were not significantly different between the community participants and UKB controls for the traits of body mass index, Type 2 diabetes, coronary artery disease, and chronotype. The mean PGSs for height were significantly lower in the community sample compared to controls (−0.21 SD units, p = 1.2 × 10−5). The results are consistent with enrichment of polygenic risk factors for psychiatric disorders in this community.
Remote C−H Pyridylation of Hydroxamates through Direct Photoexcitation of O‐Aryl Oxime Pyridinium Intermediates
Authors: Kweon Byeongseok , Kim Changha , Kim Seonyul , Hong Sungwoo 
Published: October 2021

AbstractHerein, we report an efficient strategy for the remote C−H pyridylation of hydroxamates with excellent ortho‐selectivity by designing a new class of photon‐absorbing O‐aryl oxime pyridinium salts generated in situ from the corresponding pyridines and hydroxamates. When irradiated by visible light, the photoexcitation of oxime pyridinium intermediates generates iminyl radicals via the photolytic N−O bond cleavage, which does not require an external photocatalyst. The efficiency of light absorption and N−O bond cleavage of the oxime pyridinium salts can be modulated through the electronic effect of substitution on the O‐aryl ring. The resultant iminyl radicals enable the installation of pyridyl rings at the γ‐CN position, which yields synthetically valuable C2‐substituted pyridyl derivatives. This novel synthetic approach provides significant advantages in terms of both efficiency and simplicity and exhibits broad functional group tolerance in complex settings under mild and metal‐free conditions.
Recent Advances in Hydrogen Peroxide Responsive Organoborons for Biological and Biomedical Applications
Authors: Saxon Eron , Peng Xiaohua 
Published: October 2021

AbstractHydrogen peroxide is the most stable reactive oxygen species generated endogenously, participating in numerous physiological processes and abnormal pathological conditions. Mounting evidence suggests that a higher level of H2O2 exists in various disease conditions. Thus, H2O2 functions as an ideal target for site‐specific bioimaging and therapeutic targeting. The unique reactivity of organoborons with H2O2 provides a method for developing chemoselective molecules for biological and biomedical applications. This review highlights the design and application of boron‐derived molecules for H2O2 detection, and the utility of boron moieties toward masking reactive compounds leading to the development of metal prochelators and prodrugs for selectively delivering an active species at the target sites with elevated H2O2 levels. Additionally, the emergence of H2O2‐responsive theranostic agents consisting of both therapeutic and diagnostic moieties in one integrated system are discussed. The purpose of this review is to provide a better understanding of the role of boron‐derived molecules toward biological and pharmacological applications.

Published: October 2021

AbstractBackground and objectivesDry peas (Pisum sativum L.) are an excellent source of functional proteins. Supercritical carbon dioxide +ethanol (SC‐CO2+EtOH) extraction was reported as a successful deflavoring approach to improve sensory attributes of pea flour. However, the effects of this extraction system on nutrient, structural, thermal, and functional characteristics of pea protein isolate (PPI) extracted from deflavored whole pea flour (DWPF) were not examined; thus, the focus of this study was to evaluate these characteristics.FindingsDeflavored PPI (DPPI) obtained from SC‐CO2+EtOH extraction had significantly (p < .05) higher moisture, total starch, and protein contents than nonextracted PPI (NPPI). Fourier transform infrared (FTIR) wavelengths associated with lipids were more intense in NPPI compared with DPPI. Significant higher denaturation temperature, protein solubility, emulsion, and foaming properties of DPPI were obtained. Structural changes in DPPI were recorded based on FTIR spectra, X‐ray diffraction pattern, and scanning electron microscopy.ConclusionSC‐CO2+EtOH extraction as a green technology significantly impacted the proximate composition, structural, thermal, and functional characteristic of PPI.Significance and noveltyEffects of SC‐CO2+EtOH extraction on pea protein characteristics have not reported in the literature. The results are crucial for adoption of this technology for physical modification of plant proteins.

Explaining the Advantageous Impact of Tertiary versus Secondary Nitrogen Center on the Activity of PNP‐Pincer Co(I)‐Complexes for Catalytic Hydrogenation of CO2
Authors: Bothra Neha , Das Shubhajit , Pati Swapan K. 
Published: October 2021

AbstractPincer ligated coordination complexes of base metals have shown remarkable catalytic activity for hydrogenation/dehydrogenation of CO2. The recently reported MeN[CH2CH2(iPr2)]2Co(I)PNP‐pincer complex was shown to exhibit substantially higher catalytic activity in comparison to the corresponding catalyst, HN[CH2CH2(iPr2)]2Co(I)PNP, bearing a secondary nitrogen center on the pincer ligand. Here, we computationally investigate the mechanisms for hydrogenation of CO2 to formate catalyzed by these two Co‐PNP complexes to explain how such a small structural difference could have a sizable impact on their catalytic activity. Plausible hydrogenation routes were examined in details and our findings provide solid support for the experimental observations. Our results reveal that such trends in catalytic activity could be explained from the lower activation barrier for the hydride transfer step upon changing the pincer nitrogen center from secondary to tertiary.

Published: October 2021

AbstractThis paper reports the first example of C−H arylation of benzene under mild conditions, using H2 as an electron source {turnover numbers (TONs)=0.7–2.0 for 24 h}. The reaction depends on a Rh‐based electron storage catalyst, and proceeds at room temperature and in aqueous solution. Furthermore, the H2 is inactive during the radical transfer step, greatly reducing unwanted side reactions.
