A novel near-infrared (NIR) fluorescent probe (SWJT-9) was designed and synthesized for the detection of hypochlorite anion (ClO−) using a diaminomaleonitrile group as the recognition site. SWJT-9 had large Stokes shift (237 nm) and showed an excellent NIR fluorescence response to ClO− with the color change under the visible light. It showed a low detection limit (24.7 nM), high selectivity, and rapid detection (within 2 min) for ClO−. The new detection mechanism of SWJT-9 on ClO− was confirmed by 1H NMR, MS spectrum, and the density functional theory (DFT) calculations. In addition, the probe was successfully used to detect ClO− in HeLa cells.

Phytoplankton closely connects with the hydrodynamics and biogeochemical environment of the ocean. While research focusing on both the physiochemical factors and hydrodynamics regulating phytoplankton has already been conducted, the coupling mechanism between mesoscale eddies and the vertical distribution of phyto plankton in the South China Sea (SCS) is still not well understood. Here, phytoplankton was studied under one weak-cold and two warm eddies along the 18°N transect in the SCS. The results show that the vertical distribution of chlorophyll (chl-a) presented a similar pattern at all four sampling stations. The mixed layer is less than 50 m. It is the same as the meridional salinity gradients that may be distinguished above a depth of 60 m. The subsurface chlorophyll maximum at the edge of a warm (WI) and cold eddy (CI) at E413 and E411 was shallower than that at the edge of a warm eddy (WII) at E407 and E409, indicating that temperature and salinity may be the important driving factors. On the whole, mesoscale eddies had a significant influence on the vertical pattern of chl-a in the SCS during the study period.

Subdural contrast effusion secondary to endovascular treatment is exceptionally rare and might be mistaken as subdural hematoma because of similar hyperattenuation on computer tomography. The authors present the case of a 13-month-old girl with a history of increased head circumference and developmental retardation. Cerebral digital subtraction angiography showed a high-flow pial arteriovenous fistula fed by multiple arteries on the right cerebellar surface, with occlusion of the right sigmoid sinus and severe stenosis of the left sigmoid sinus. Staged endovascular treatments were performed to eliminate the fistula. Follow-up head computer tomography scans performed 3 h after both procedures demonstrated typical high-density subdural effusion with computer tomography attenuation value similar to hemorrhage. These effusions did not aggravate the condition and disappeared spontaneously 32 h after the first treatment and 29 h after the second, respectively.

Seed dispersal selection pressures may cause morphological differences in cone structure and seed traits of large‐seeded pine trees. We investigated the cone, seed, and scale traits of four species of animal‐dispersed pine trees to explore the adaptations of morphological structures to different dispersers. The four focal pines analyzed in this study were Chinese white pine (Pinus armandi), Korean pine (P. koraiensis), Siberian dwarf pine (P. pumila), and Dabieshan white pine (P. dabeshanensis). There are significant differences in the traits of the cones and seeds of these four animal‐dispersed pines. The scales of Korean pine and Siberian dwarf pine are somewhat opened after cone maturity, the seeds are closely combined with scales, and the seed coat and scales are thick. The cones of Chinese white pine and Dabieshan white pine are open after ripening, the seeds fall easily from the cones, and the seed coat and seed scales are relatively thin. The results showed that the cone structure of Chinese white pine is similar to that of Dabieshan white pine, whereas Korean pine and Siberian dwarf pine are significantly different from the other two pines and vary significantly from each other. This suggests that species with similar seed dispersal strategies exhibit similar morphological adaptions. Accordingly, we predicted three possible seed dispersal paradigms for animal‐dispersed pines: the first, as represented by Chinese white pine and Dabieshan white pine, relies upon small forest rodents for seed dispersal; the second, represented by Korean pine, relies primarily on birds and squirrels to disperse the seeds; and the third, represented by Siberian dwarf pine, relies primarily on birds for seed dispersal. Our study highlights the significance of animal seed dispersal in shaping cone morphology, and our predictions provide a theoretical framework for research investigating the coevolution of large‐seeded pines and their seed dispersers., We investigated the cone, seed, and scale traits of four species of animal‐dispersed pine trees, and predicted three possible seed dispersal paradigms for animal‐dispersed pines: the first, as represented by Chinese white pine and Dabieshan white pine, relies upon small forest rodents for seed dispersal; the second, represented by Korean pine, relies primarily on birds and squirrels to disperse the seeds; and the third, represented by Siberian dwarf pine, relies primarily on birds for seed dispersal.

OBJECTIVE: To investigate the incidence of preterm birth and risk factors for preterm birth. METHODS: A prospective cohort study was performed for the pregnant women in early pregnancy and their spouses, who underwent prenatal examination for the first time in Hunan Provincial Maternal and Child Health Care Hospital from May 2014 to December 2016 and decided to be hospitalized for delivery. A questionnaire survey was performed to collect exposure information possibly related to preterm birth. The hospital's medical record system was used for information verification and to record the pregnancy outcome. A multivariate logistic regression analysis was used to investigate the risk factors for preterm birth. RESULTS: A total of 6 764 pregnant women with complete data were included, and the incidence rate of preterm birth was 17.09%. The multivariate logistic regression analysis showed that a history of adverse pregnancy outcomes, eating areca nut before pregnancy, a history of pregnancy complications, a history of hepatitis, no folate supplementation during pregnancy, medication during pregnancy, active smoking and passive smoking during pregnancy, drinking during pregnancy, unbalanced diet during pregnancy, high-intensity physical activity during pregnancy, and natural conception after treatment of infertility or assisted conception as the way of conception were risk factors for preterm birth (P

In order to suppress the effect of the temperature variation on the wavefront of the laser communication terminal, the secondary mirror support with flexure hinges is designed. The series-wound straight-circle flexure hinge is designed to achieve the maximal variation range of the flexibility or stiffness with the limit of flexure hinges geometrical size. The position and quantity of the flexure hinges are determined to control the deformation direction of the secondary mirror. In order to search the direction in which the wavefront aberration is minimum, the flexure hinges parameters are optimized with the system wavefront aberration as the optimization objective. The prototype of the laser communication terminal is constructed and the value of the wavefront aberration is measured under the condition of 20 ± 2°C. Experimental results show that the value of the wavefront aberration root mean square (RMS) is reduced from 0.066λ to 0.042λ, meeting the requirement of RMS less than 1/20λ (λ=632.8 nm). The athermal design method presented in this paper provides a novel way for the athermal design of the small aperture mirror support in off-axis optical systems.

A metabolic illness known as non-alcoholic fatty liver disease (NAFLD), affects more than one-quarter of the world’s population. Bile acids (BAs), as detergents involved in lipid digestion, show an abnormal metabolism in patients with NAFLD. However, BAs can affect other organs as well, such as the brain, where it has a neuroprotective effect. According to a series of studies, brain disorders may be extrahepatic manifestations of NAFLD, such as depression, changes to the cerebrovascular system, and worsening cognitive ability. Consequently, we propose that NAFLD affects the development of brain disease, through the bile acid signaling pathway. Through direct or indirect channels, BAs can send messages to the brain. Some BAs may operate directly on the central Farnesoid X receptor (FXR) and the G protein bile acid-activated receptor 1 (GPBAR1) by overcoming the blood–brain barrier (BBB). Furthermore, glucagon-like peptide-1 (GLP-1) and the fibroblast growth factor (FGF) 19 are released from the intestine FXR and GPBAR1 receptors, upon activation, both of which send signals to the brain. Inflammatory, systemic metabolic disorders in the liver and brain are regulated by the bile acid-activated receptors FXR and GPBAR1, which are potential therapeutic targets. From a bile acid viewpoint, we examine the bile acid signaling changes in NAFLD and brain disease. We also recommend the development of dual GPBAR1/FXR ligands to reduce side effects and manage NAFLD and brain disease efficiently.

The dried rhizomes of Paris polyphylla Smith var. yunnanensis (Franch.) Hand.-Mazz. (PPY, family Melanthiaceae), which are well-recognized as “Dian Chonglou” in Chinese and recorded as one of the original plants of traditional Chinese medicine (TCM) Paridis Rhizoma in the Chinese Pharmacopeia (from 1977 to 2020 editions), have been widely used in TCM as indispensable ingredients in over 100 patent medicines. PPY is mainly distributed in Southwest China and has been cultivated on a large scale in Yunnan Province for its important medicinal properties. The rhizomes have been traditionally used to treat traumatic injuries, abscesses, mastitis, chronic bronchitis, and hepatopathy. This chapter presents a systematic and comprehensive overview of the ethnopharmacological usages of PPY, its traditional uses, phytochemical constituents, and pharmacological activities, including quality control, pharmacokinetics, and toxicological studies of PPY.

Motivated by the Novikov equation and its peakon problem, we propose a new mixed type Hermite--Pad�� approximation whose unique solution is a sequence of polynomials constructed with the help of Pfaffians. These polynomials belong to the family of recently proposed partial-skew-orthogonal polynomials. The relevance of partial-skew-orthogonal polynomials is especially visible in the approximation problem germane to the Novikov peakon problem so that we obtain explicit inverse formulae in terms of Pfaffians by reformulating the inverse spectral problem for the Novikov multipeakons. Furthermore, we investigate two Hermite--Pad�� approximations for the related spectral problem of the discrete dual cubic string, and show that these approximation problems can also be solved in terms of partial-skew-orthogonal polynomials and nonsymmetric Cauchy biorthogonal polynomials. This formulation results in a new correspondence among several integrable lattices., 37 pages; to appear in Advances in Mathematics

Univariate and multivariate analysis were utilized to analyze the relationship between prognosis and clinicopathological characteristics including TCF7L2 expression.RESULTS: Compared with low-grade glioma group, the expression of TCF7L2 was significantly increased (pCONCLUSIONS: Our research proved that TCF7L2 was over- expressed in glioblastoma, and, related with tumor prognosis, which, therefore, could be an independent prognostic factor for glioma patients.

Aim: The current geographic distribution of plants and their dispersers are a result of coevolution, but the reciprocity effects on the distribution of large seed pine and primary seed dispersers required understanding of (a) the distribution range and distribution characteristics of each species, and (b) the overlapping of distribution areas of animals and plants to explore whether they match. Location: China Methods: To find the target species, we identified eight large-seeded pine species in China in terms of seed size and wing traits as well as four primary seed disperser species in terms of body size, diet and food storage behavior. To map the geographical distribution, we obtained species distribution information from books, literature and GBIF. We then analyzed the distribution relationship by overlapping the distribution areas and patterns comprehensively. Results: We identified eight species of large-seeded pines (Pinus fenzeliana, P. gerardiana, P. dabeshanensis, P. koraiensis, P. pumila, P. bungeana, P. armandii, and P. sibirica) and four species of primary seed dispersers (Nucifraga caryocatactes, Sciurus vulgaris, Tamias sibiricus, and Sciurotamias davidianus). Pines interlaced from the Northeast to the Southwest of China along the mountains with an average altitude of 1000-2000 m, while each species of seed disperser had a wide distribution range that overlapped completely or partially with that of four or more species of the large-seeded pines. For pines that lack sufficient research on seed dispersal, our research provides them with potential seed dispersers Main conclusions: The distribution pattern of large-seeded pines and the primary seed dispersers was matched, we believed that reciprocal relationship promotes this distribution pattern. Our study highlights the importance of incorporating the ecological consequences of geographical distribution into reciprocal interactions between species and biodiversity conservation.

Surface wear is an inevitable damage of wire ropes used in winding hoist. It always reduces the service life of the wire rope and threatens the mine safety. The characteristics of the surface wear scar caused by sliding contact between ropes were discussed in a quantitative and qualitative method for this paper. A series of breaking tensile tests were carried out to investigate the effects of the wear characteristic parameters on the bearing capacity of the rope. Furthermore, the fracture failure behaviors of the rope with different wear scars were analyzed. Results show that the wear scar changes from distributing on one strand to evenly distributed on two adjacent strands as the sliding wear position changes from the strand peak to valley. When the wear region concentrates on one strand, the maximum wear depth increases from approximately 0.46 mm to approximately 0.64 mm with the increase of wear area. Broken wires seriously affect the elongation and breaking force of the rope. The maximum breaking force is approximately 42 KN and the maximum local elongation is approximately 1.5 mm under the condition of broken wires. Additionally, the external wires of the strand are easier to fracture caused by torsion and tension together. Furthermore, the shear lip and the fibre region on the fracture surface of the wires become not very obvious with the increase of the wear scar parameters.

Objective Here we aimed to investigate the difference in clinical characteristics and outcomes between pediatric and adult patients with COVID-19. Methods A total of 333 consecutive patients with laboratory-confirmed SARS-CoV-2 infection treated in the departments of Internal medicine of Shenzhen Third People’s Hospital from January 11th to February 10th, 2020 were included. The data were obtained from electronic medical records. The epidemiological data, clinical characteristics, length of hospital stays, and outcomes of pediatric and adult patients were compared. Results Compared with adult patients, pediatric patients had a shorter time of symptom onset to hospitalization than adults [median time, 1 (IQR, 1.0–1.0) d vs. 3 (IQR, 2.0–6.0) d, P < 0.001], milder or fewer symptoms, less severe chest CT findings. The clinical severity classification of children was less severe than adults. Up to 15th March, the end of the follow-up, 33 (100%) children and 292 (97.3%) adult patients had been discharged from hospital. Only 2 (0.7%) adult patients died, with an overall case mortality of 0.6%. The median length of hospital stay of pediatric patients was shorter than that of adult patients [19 (95% CI: 16.6–21.4) d vs. 21 (95% CI: 19.9–22.1) d, P = 0.024]. Conclusion Pediatric patients with COVID-19 had milder or less clinical symptoms, less evident pulmonary imaging changes, better prognosis, and shorter length of hospital stay.

Cucumber mosaic virus (CMV) has an extensive host range, however there are few reports of CMV infecting fruit crops in China. In this study, CMV was detected using RT-PCR and Western blot from six kinds of fruit crops including pear in Heilongjiang province, apricot, grape, peach, Castanea mollissima and Malus spectabilis in Shandong province in China. This is the first report of CMV naturally infecting these six fruit crops in China. In addition, this is also the first report of CMV in Heilongjiang province which is the northest province of China.

Studies on key influencing factors (coil’s size and excitation frequency) of eddy current testing (ECT) sensitivity, monotonicity and defect detectability have been carried out for detection of subsurface defects in ferromagnetic and non-ferromagnetic plate materials. A set of ECT finite element models and experiments have been accomplished and the detection performance has been analyzed and compared. The simulation and experiment results have indicated that for ferromagnetic material, the amplitude response of low frequency excitation has lower sensitivity but better monotonicity than high frequency. The phase response of low frequency excitation has higher sensitivity and better monotonicity than high frequency. For the non-ferromagnetic plate material, the lower the excitation frequency is, the smaller the detection sensitivity of the amplitude response is. Outside a defined excitation frequency, the defect monotonicity of the amplitude response reduces. For phase response, the lower the excitation frequency is, the smaller the detection sensitivity and the greater the monotonicity. The coil’s size has a certain extent influence on the detection sensitivity. For ferromagnetic and non-ferromagnetic plate materials, it is effective to enhance the detection sensitivity of amplitude response by increasing the size of the exciter coil and the detector coil within a certain range; and it is effective to enhance the detection sensitivity of phase response by decreasing the size of the detector coil or increasing the size of exciter coil within a certain range.

A novel two-site chemodosimeter (SWJT-4) based on fluorescein skeleton to detect diethyl chlorophosphate (DCP) was designed and synthesized. It is a turn-on fluorescent probe for DCP with good selectivity and obvious color change in aqueous solution. Interestingly, the two oxime groups of SWJT-4 as dual response sites initiated different reactions with DCP to form a cyano group and an isoxazole ring, respectively. The corresponding mechanism was confirmed by 1H NMR, MS and DFT calculation. Moreover, SWJT-4 could be used as a fluorescent test paper to detect DCP vapor.

C8 light hydrocarbons (LHs) were characterized for 23 crude oils from two different deposits by comprehensive two-dimensional gas chromatography. Dimethylcyclohexanes (DMCyC6) and trimethylcyclopentanes (TMCyC5) are the predominant compounds in C8 LHs and geochemically significant. Used in tandem with deposition-diagnosed parameters such as pristane/phytane (Pr/Ph), dibenzothiophene/phenanthrene (DBT/P), C22/C21 tricyclic terpane (C22/C21TT), C29/C30 hopane (C29/C30H), and monoterpane ratios (MT1, MT2, and MTR), C8R ratio ((1trans,4-+1cis,3-+1,1-) DMCyC6/(1cis,2trans,4cis- + 1cis,2trans,3cis-) TMCyC5) can distinctly distinguish marine oils derived from source rocks deposited under anoxic conditions from the terrigenous oils originated from source rocks deposited in oxic/suboxic conditions, for their lower C8R (

In this article, we consider the generalised two-parameter Cauchy two-matrix model and corresponding integrable lattice equation. It is shown that with parameters chosen as $1/k_i$ when $k_i\in\mathbb{Z}_{>0}$ ($i=1,\,2$), the average characteristic polynomials admit $(k_1+k_2+2)$-term recurrence relations, which provide us spectral problems for integrable lattices. The tau function is then given by the partition function of the generalised Cauchy two-matrix model as well as Gram determinant. The simplest example with exact solvability is demonstrated., 15 pages; comments are welcome

Wear problems exist in multi-layer windings of ultra-deep coal mine hoisting ropes that are wound around drums. Wear decreases the life of such hoisting ropes directly, and that in turn threatens mine safety. An investigation of winding hoisting ropes was conducted using a custom test rig to study the effects of different contact loads, crossing angles and displacement amplitudes on rope friction and wear. Results show that the coefficient of friction (COF) in the steady-state period changes very little with an increase in contact load and that it stabilizes at about 0.61. Additionally, the COF slightly decreases with an increase of crossing angle. As the amplitude of sliding motion increases to 30 mm and 50 mm, the COF increases linearly. Using thermal imaging, the temperature rise in the steady-state period increases with the contact load and crossing angle. Moreover, the maximum wear depth increases linearly with an increase of contact load. Nevertheless, the wear depth changed very little when the amplitude is less than 30 mm, but it increases rapidly until an amplitude of 70 mm. The major wear mechanisms of ropes without lubrication include adhesive wear, abrasive wear and fatigue wear.

Background Previous studies have highlighted that negative life events and emotional intelligence are significant predictors of mental health. However, whether emotional intelligence mediates the relationship between negative life events and psychological distress among nursing students have not been given adequate attention. Objectives To explore the relationship among negative life events, emotional intelligence and psychological distress and to examine the mediating role of emotional intelligence in psychological distress among Chinese nursing students. Design A cross-sectional survey using convenience sampling. Settings and Participants A total of 467 nursing students who were enrolled in a university in mainland of China. Methods A structured questionnaire was administered from September–November in 2013 to participants who consented to participate in the study. Independent variables were personal variables, emotional intelligence and negative life events. Outcome variable was psychological health. The means and standard deviations were computed. Student's t -test and one-way analysis of variance (ANOVA) were performed, to test the differences among the demographic characteristics on the psychological distress scores. Pearson correlation analyses and hierarchical regression analyses were performed. Results Negative life events were positively associated with psychological distress. Emotional intelligence was negatively associated with psychological distress and negative life events. Emotional intelligence mediated the relationship between negative life events and psychological distress. Conclusions The findings support the theory of Salovey and his colleagues, and provide evidence for emotional intelligence as a factor that buffers effects of negative life events on psychological distress.

Rationale: Hiccups are a common clinical symptom, and persistent hiccups and intractable hiccups severely impair the individual's quality of life. To date, there has been no effective treatment specifically for hiccups. Herein, we report 2 cases with intractable or persistent hiccups that were successfully treated with extracranial acupuncture. Patient concerns: The first case is a 46-year-old woman who presented with a 7-year history of intractable hiccups that had worsened over the past 3 years. She also complained of chest tightness, dyspnea, palpitations, dreaminess, dysphoria, intolerance of cold, and hypohidrosis. The second case is a 75-year-old man who presented with a 7-day history of persistent hiccups and hematemesis for 3 hours. The patient's persistent hiccups were treated using traditional Chinese acupuncture, but the patient reported no remarkable benefit. Diagnoses: They were diagnosed as intractable or persistent hiccups. Interventions: They were treated with extracranial acupuncture. Outcomes: The hiccups completely disappeared. During the follow-up period, the hiccups did not reappear. Lessons: According to neural balance theory, an episode of the hiccups is caused by an imbalance of the nervous system. Extracranial acupuncture in the area adjacent to the external occipital protuberance affects the intracranial nervous system, which can effectively control the hiccups. Our study provides a new approach to the treatment of hiccups.

In order to improve the retrieval accuracy of ocean aerosol , quantitative study was carried out in terms of the multi-spectral polarized properties of the aerosol in visible and near-infrared wavebands. Firstly, an aerosol model and a sea surface model were built. And the vector radiative transfer procedure of light in aerosol and atmosphere-ocean interface was simulated accurately based on the successive order of scattering method. Then from the perspective of the spectrum, the reflectance and polarized reflectance at the top of atmosphere in typical wavebands were quantitatively analyzed. Based on this, the spectrum distribution model of ocean aerosol polarized radiation was presented. And the model was validated with satellite data. Lastly, the influences of aerosol optical depth, viewing angle, chlorophyll a concentration and wind speed on multi-spectral polarized radiation of ocean aerosol were studied. The study shows that the changes of aerosol multi-spectral polarized radiation with wavelength can be best described with power function model when ignoring the absorbtion of atmosphere and solar flare effect in visible and near-infrared wavebands. This phenomenon can be caused by Rayleigh scattering and Mie scattering.The influences of chlorophyll a concentration and wind speed on multi-spectral polarized radiation of ocean aerosol emerge as very different in different wavebands. Specifically, the influences of chlorophyll a concentration on reflectance and polarized reflectance both can be neglected in near-infrared waveband. But in visible waveband, the influence on the reflectance must not be neglected any longer. Due to the increasement of the wind speed, the reflectance and the polarized reflectance increased significantly. But there are differences in the increases in different wavebands. The multi-spectral polarized radiative information of ocean aerosol can embody its own charactersitics effectively. And furthermore, the change of polarized reflectance with each factor has more obvious differences in different wavebands compared with reflectance. As a result, the multi-spectral polarized information of ocean aerosol can be used to retrieve the parameters of the aerosol over the ocean. The achievement of multi-spectral information has great significance for improving the retrieval accuracy of the ocean aerosol.

In order to meet the demand of integrated data transmission for electronic systems of aerocraft and ground vehicles, the FC-AE-1553 protocol and IP protocol can be supported on the fiber channel network. The FC-AE-1553 protocol supports periodic service and strong timing service and uses the fixed bandwidth and preemptive bandwidth allocation. IP protocol supports burst service and uses dynamic bandwidth allocation mechanism based on weight ratio. In this paper, a multi service FC network simulation platform is constructed, and the scheduling mechanism is analyzed by combining theoretical analysis with simulation. The results show that compared with the traditional command response scheduling mechanism, the proposed strategy can increase the average throughput of the network by more than 10 times, the network throughput can be increased from 2.8Gbps to 46Gbps, and the average delay of IP packets can be reduced by 1 order of magnitude.

The removal efficiencies of algal organic matter (AOM) and typical nitrogenous and non-nitrogenous disinfection by-products (DBPs) through adsorption with powder activated carbon (PAC) were investigated. Three-dimensional fluorescence spectroscopy confirmed that PAC adsorption changed the composition of AOM. PAC adsorption showed high removal efficiency for humus-like substances in AOM, but limited removal efficiency for aromatic protein-like substances. When the dosage of PAC was 20 mg·L
