Abstract: Grain boundary (GB) failure in tungsten under shock loading after irradiation is a key factor to estimate the performance of tungsten as a plasma facing material in nuclear fusion reactors and as a target in spallation neutron sources. In this work, GB evolution after absorption of different radiation defect clusters under shock loading has been investigated at atomic scale through non-equilibrium molecular dynamics (NEMD) method. Different to the cases without radiation defects, after absorption of interstitial dislocation loops and voids, two mechanisms have been identified for the decrease of critical shock velocity (vc) and the related GB failure. The direct void growth accompanied by appearance of disordered structure around void, from the remaining vacancy cluster which could not be annihilated by compressive stress wave, is the 1st mechanism. In the 2nd mechanism, activation of slip systems, dislocation formation, motion and multiplication, void nucleation and growth dominate the failure process. The higher potential energy and local stress concentration around a defect absorption region in GB are recognized for atomic motion deviations from shock loading direction, resulting in formation of disordered structure, activation of slip system and dislocation multiplication with lower vc under coupling effects of radiation damage and shock loading. These results indicate that under a high dose of radiation damage, GB failure induced by shock loading should be considered seriously in order to estimate the lifetime of tungsten-based plasma facing materials and spallation target materials.

Abstract: Aging reduces the nutritional value of corn grain, which may be improved by fermentation prior to use. This study investigated the effects of replacing conventional corn (CC) with aging corn (AC) and fermented aging corn (FAC) in the diets of lactating Holstein cows. Six healthy third-parity Holstein cows were used in a replicated 3 × 3 Latin square experiment with 21-day periods. Cows were fed twice and milked twice daily. The cows were randomly divided into three treatment groups: (1) CC diet: a diet with 23.6% starch in diet DM containing 24.0% conventional corn; (2) AC diet: a diet with 23.5% starch in diet DM containing 24.0% aging corn replacing conventional corn; and (3) FAC diet: a diet with 23.2% starch in diet DM containing 24.6% fermented aging corn replacing conventional corn. The diets were formulated to be isonitrogenous and contained identical roughage. The FAC treatment increased the starch digestibility compared with AC. Feeding FAC increased the concentrations of total volatile fatty acid compared with CC and AC and decreased the molar proportion of acetate compared with AC. At the family level, the relative abundance of Prevotellaceae was higher on FAC than CC. The relative abundance of Succinivibrionaceae was lower on FAC than on CC and AC. Besides, at the genera level, the relative abundance of Succinivibrionaceae_UCG_002 in the rumen was higher on AC than CC and FAC. The relative abundance of Prevotella and Ruminococcus was higher on FAC than CC and AC. The relative abundance of Succinivibrionaceae_UCG_001 was lower on FAC than CC. The Simpson index was lower on FAC than CC and AC. The FAC treatment increased the milk yield (34.0, 33.7, and 35.2 kg/d for CC, AC, and FAC group, respectively) and protein yield, and thus, energy-corrected milk production was increased, and at the same time, decreased the somatic cell score compared with CC and AC. The AC treatment increased the malondialdehyde concentration in plasma compared with CC and FAC. The concentrations in plasma of triglyceride and malondialdehyde were lower on FAC than AC. The immunoglobulin G concentration in plasma was higher on FAC than CC and AC. Overall, feeding AC resulted in decreased plasma antioxidant capacity compared with CC, whereas feeding FAC altered the relative abundance of bacteria in the rumen and improved starch digestibility, ruminal bacterial diversity, lactation performance, plasma antioxidant capacity and immune competence compared with AC in dairy cows.

Abstract: A massless particle beyond the Standard Model is searched for in the two-body decay Σ+→p+invisible using (1.0087±0.0044)×1010 J/ψ events collected at a center-of-mass energy of s=3.097GeV with the BESIII detector at the BEPCII collider. No significant signal is observed, and the upper limit on the branching fraction B(Σ+→p+invisible) is determined to be 3.2×10−5 at the 90% confidence level. This is the first search for a flavor-changing neutral current process with missing energy in hyperon decays which plays an important role in constraining new physics models.

Abstract: The grain size of aluminum alloy is closely related to solute content and solidification conditions. This study investigated the influence of Si content on the solidification microstructure and properties of the Al–Si binary alloy by experiments and phase field simulation. The experimental results indicated that the microstructure of Al–Si alloy changes from coarse columnar grains to uniformly distributed equiaxed grains as Si content increases from 0 to 7 wt%, and the average grain size of Al–2Si is the smallest (2.2 mm). Meanwhile, the tensile strength of Al–Si alloys increases from 56.9 MPa to 111 MPa with increasing Si content, whereas the ductility decreases from 30% to 2.5%. Moreover, high casting temperature will produce coarse columnar crystals, low casting temperature forms equiaxed crystals, the optimal casting temperature in this study is 30 °C above the liquidus. Phase field simulations reveal that the evolution of Al–Si microstructures is governed by two dimensionless parameters: the initial temperature (T0), related to casting temperature and solidification interval, and the latent heat (K1), connected to latent heat, specific heat, and solidification interval. For a certain alloy composition (Al–2Si), the grain size exhibits a non-monotonic trend, decreasing initially and then increasing as T0 increases, with an optimal T0 value of 1.42. When the Si content varies between 2 and 7 wt%, the average grain sizes decrease as K1 increases, with the maximum K1 value observed at 1.38 for Al–2Si.

Abstract: The spin and parity of the charmed mesons Ds⁎+, D⁎0 and D⁎+ are determined for the first time to be JP=1− with significances greater than 10σ over other hypotheses of 2+ and 3−, using an e+e− collision data sample with an integrated luminosity of 3.19 fb−1 collected by the BESIII detector at a center-of-mass energy of 4.178 GeV. Different spin-parity hypotheses are tested via a helicity amplitude analysis of the processes e+e−→Ds⁎+Ds−, D⁎0D0 and D⁎+D−, with Ds⁎+→Ds+γ, D⁎0→D0π0, and D⁎+→D+π0. The results confirm the quark model predictions.

Abstract: We report a search for a dark photon using 14.9 fb−1 of e+e− annihilation data taken at center-of-mass energies from 4.13 to 4.60 GeV with the BESIII detector operated at the BEPCII storage ring. The dark photon is assumed to be produced in the radiative annihilation process of e+e− and to predominantly decay into light dark matter particles, which escape from the detector undetected. The mass range from 1.5 to 2.9 GeV is scanned for the dark photon candidate, and no significant signal is observed. The mass dependent upper limits at the 90% confidence level on the coupling strength parameter ϵ for a dark photon coupling with an ordinary photon vary between 1.6×10−3 and 5.7×10−3.

Abstract: Abstract Using 448.1 × 106 ψ(3686) decays collected with the BESIII detector at the BEPCII e + e − storage rings, the branching fractions and angular distributions of the decays χ cJ → Ξ − Ξ ¯ $$ \overline{\Xi} $$ + and Ξ0 Ξ ¯ $$ \overline{\Xi} $$ 0 (J = 0, 1, 2) are measured based on a partial-reconstruction technique. The decays χ c1 → Ξ0 Ξ ¯ $$ \overline{\Xi} $$ 0 and χ c2 → Ξ0 Ξ ¯ $$ \overline{\Xi} $$ 0 are observed for the first time with statistical significances of 7σ and 15σ, respectively. The results of this analysis are in good agreement with previous measurements and have significantly improved precision.

Abstract: We search for an axion-like particle (ALP) a through the process ψ(3686)→π+π−J/ψ, J/ψ→γa, a→γγ in a data sample of (2.71±0.01)×109 ψ(3686) events collected by the BESIII detector. No significant ALP signal is observed over the expected background, and the upper limits on the branching fraction of the decay J/ψ→γa and the ALP-photon coupling constant gaγγ are set at 95% confidence level in the mass range of 0.165≤ma≤2.84GeV/c2. The limits on B(J/ψ→γa) range from 8.3×10−8 to 1.8×10−6 over the search region, and the constraints on the ALP-photon coupling are the most stringent to date for 0.165≤ma≤1.468GeV/c2.

Abstract: This paper presents the development of numerical modelling to simulate thermal and moisture mapping of layered cricket helmets. The 3D laser scanning methodology was used to obtain geometrical data of a dummy human head with non-ventilated (NVL) and ventilated (VL) helmets to generate the meshes. Here, heat transfer and mass diffusion were applied in the finite element simulations to model the temperature and relative humidity (RH) distributions inside NVL and VL helmets, which were processed as the temperature-time and RH-time charts. The simulated results were validated against the corresponding experimental measurements with reasonably good correlation, in terms of the general trend on reginal temperature and RH against time, although parameters such as helmet movement and local sweating were not considered in the modelling to simplify the simulation. The discrepancies between the FE simulation results and the measurements are generally within 7% for in-helmet temperature and 5% for RH, for both types of helmets in the low ambient conditions (20 °C and 50% RH), although such the discrepancy is about 10% for the VL helmet subjected to the high ambient conditions (35 °C and 30% RH). The models developed are ready to be used for parametric studies on non-ventilated helmet to optimize the ventilation openings for improving the thermal comfort.

Subjects: BESIII, Σ0 hyperon, Born cross section, Form factor, Physics, QC1-999
Abstract: The Born cross sections of e+e−→Σ0Σ¯0 are measured at center-of-mass energies from 2.3864 to 3.0200 GeV using data samples with an integrated luminosity of 328.5 pb−1 collected with the BESIII detector operating at the BEPCII collider. The analysis makes use of a novel reconstruction method for energies near production threshold, while a single-tag method is employed at other center-of-mass energies. The measured cross sections are consistent with earlier results from BaBar, with a substantially improved precision. The cross-section lineshape can be well described by a perturbative QCD-driven energy function. In addition, the effective form factors of the Σ0 baryon are determined. The results provide precise experimental input for testing various theoretical predictions.

12. Levonorgestrel intrauterine system versus oral progestin for preventing the recurrence of endometrial polyps after hysteroscopic resection: A meta-analysis of 19 randomized controlled trials

Author: Y. Sun, X. Chen, X. Yuan, L. Xu, Y.C. Jin, T.H. Ji, X.L. Wang, H.H. Dai, and W.J. Cheng
Subjects: endometrial polyps, levonorgestrel intrauterine system, lng-ius, oral progestin, meta-analysis, Gynecology and obstetrics, RG1-991
Abstract: Background: The aim of this meta-analysis was to compare levonorgestrel intrauterine system (LNG-IUS) with oral progestin for preventing the recurrence of endometrial polyps after hysteroscopic resection. Materials and Methods: Computerized literature search was performed in PubMed and several Chinese databases to screen for relevant trials. Quality assessment and meta-analysis were performed for the included trials. Results: A total of 19 randomized controlled trials were identified. Meta-analysis indicated that the LNG-IUS group was associated with lower recurrence rate of endometrial polyps than the oral progestin group (p < 0.0001), while there was no significant difference in the incidence of abnormal uterine bleeding between groups (p > 0.05). In terms of adverse effects related to progestin, the LNG-IUS group had significantly fewer adverse effects than the oral progestin group (p < 0.0001). Additionally, the LNG-IUS group had thinner endometrium and higher hemoglobin levels than the oral progestin group (p < 0.00001). Conclusion: The LNG-IUS was more effective and safer in preventing the recurrence of endometrial polyps after hysteroscopic resection than oral progestin.

Abstract: Plasmodiophora brassicae is a biotrophic pathogen causing clubroots of cruciferous crops. The Brassica rapa accession T1-145 has an ability to produce small spheroid galls (SSGs), which represent neither a fully compatible interaction nor a complete resistance. To explore the defense response in SSGs induced by P. brassicae infection, global transcriptome profiling SSGs was performed at different time points. By comparing gene expression patterns, we identified many defense related genes. The first group included genes encoding receptor-like protein/kinases, such as cysteine-rich receptor-like protein kinases, receptor-like proteins, phloem intercalated with xylem/tracheary element differentiation inhibitory factor receptor (PXY/TDR), PXY-correlated 1, wall-associated kinases, nuclear shuttle protein-interacting kinase, lectin receptor-like kinases, and flagelin-sensitive 2, which might activate a basal defense. The second group involved robust effector-triggered immunity response genes such as resistance to leptosphaeria maculans 1B, constitutive shade-avoidance 1, target of avirulence B operation 1, ribosomal protein of the small subunit 6, resistance to Pseudomonas maculicola 1-interacting protein 4, enhanced disease resistance 2L, and recognition of Peronospora parasitica 13-like protein 4. The third group included genes encoding secondary cell wall formation related protein/s, a nodulin-like protein, a germin-like protein, a jacalin-related lectin, a defensin-like protein, tumor inhibitors, and sugars will eventually be exported transporter, which might contribute to quantitative resistance against P. brassicae. The gene expressions were the highest at the late stage of infection. To our knowledge, it is the first report on exploring defense response genes during SSG occurrence by a transcriptome analysis. Our data would provide useful information to further explore molecular mechanisms of the incomplete resistance.

14. Light stability of the isolated CP43 studied by infrared and terahertz spectroscopy

Author: Y.G. QU, X.L. WANG, and T.Y. KUANG
Subjects: amide i band, conformation, degradation, photoinhibition, Botany, QK1-989
Abstract: Here, the light-induced changes of the core antenna complex chlorophyll protein 43 (CP43) isolated from PSII of spinach were assessed using infrared and terahertz (THz) spectroscopy. We found that the collective vibrational modes at low frequencies and the secondary structures of CP43 were altered upon illumination. The helix changed more than any other secondary structure. CP43 is more easily damaged by illumination than PSII. Infrared and THz spectroscopy have different functions in protein studies. THz spectroscopy has potential in evaluating the stability of proteins.

Abstract: Using e+e− collision data at ten center-of-mass energies between 2.644 and 3.080 GeV collected with the BESIII detector at BEPCII and corresponding to an integrated luminosity of about 500 pb−1, we measure the cross sections and effective form factors for the process e+e−→Ξ0Ξ¯0 utilizing a single-tag method. A fit to the cross section of e+e−→Ξ0Ξ¯0 with a pQCD-driven power function is performed, from which no significant resonance or threshold enhancement is observed. In addition, the ratio of cross sections for the processes e+e−→Ξ−Ξ¯+ and Ξ0Ξ¯0 is calculated using recent BESIII measurement and is found to be compatible with expectation from isospin symmetry.

Abstract: Using 5.9 pb−1 of e+e− annihilation data collected at center-of-mass energies from 3.640 to 3.701 GeV with the BESIII detector at the BEPCII Collider, we measure the observed cross sections of e+e−→KS0X (where X=anything). From a fit to these observed cross sections with the sum of continuum and ψ(3686) and J/ψ Breit-Wigner functions and considering initial state radiation and the BEPCII beam energy spread, we obtain for the first time the product of ψ(3686) leptonic width and inclusive decay branching fraction Γψ(3686)eeB(ψ(3686)→KS0X)=(373.8±6.7±20.0) eV, and assuming Γψ(3686)ee is (2.33±0.04) keV from PDG value, we measure B(ψ(3686)→KS0X)=(16.04±0.29±0.90)%, where the first uncertainty is statistical and the second is systematic.

Abstract: Barnyard grass (Echinochloa crus-galli) is a troublesome graminaceous weed infesting rice fields in the Yangtze River Basin, China. However, the effects of barnyard grass on rice root physiology are unclear. In this study, the effects of barnyard grass, planted at different densities (ranging from 2-8 plants m-2), on rice performance were evaluated, including chlorophyll fluorescence parameters, Rubisco activity, root oxidation activity, and the zeatin + zeatin riboside concentration. The results indicated that rice photosynthesis and physiological characteristics decreased as the density of barnyard grass increased. The rice net photosynthetic rate significantly declined and ranged between 17.3-10.5% compared with the control (0 barnyard grass plants m-2). The results showed that rice grain yields decreased to 58% when barnyard grass was planted at a density of 8 plants m-2. We found that barnyard grass can reduce the Rubisco activity, leaf photosynthetic capacity, and energy conversion efficiency in rice, thus resulting in the reduced rice yield.

Abstract: The electromagnetic process e+e−→pp¯ is studied with the initial-state-radiation technique using 7.5 fb−1 of data collected by the BESIII experiment at seven energy points from 3.773 to 4.600 GeV. The Born cross section and the effective form factor of the proton are measured from the production threshold to 3.0 GeV/c2 using the pp¯ invariant-mass spectrum. The ratio of electric and magnetic form factors of the proton is determined from the analysis of the proton-helicity angular distribution.

Abstract: Based on 586 pb−1 of e+e− annihilation data collected at a center-of-mass energy of s=4.6GeV with the BESIII detector at the BEPCII collider, the absolute branching fraction of Λc+→pKS0η decays is measured for the first time to be B(Λc+→pKS0η)=(0.414±0.084±0.028)%, where the first uncertainty is statistical and the second is systematic. The result is compatible with a previous CLEO result on the relative branching fraction B(Λc+→pKS0η)B(Λc+→pK−π+), and consistent with theoretical predictions of SU(3) flavor symmetry.

Abstract: The Born cross sections of the e+e−→Σ+Σ¯− and e+e−→Σ−Σ¯+ processes are determined for center-of-mass energy from 2.3864 to 3.0200 GeV with the BESIII detector. The cross section lineshapes can be described properly by a pQCD function and the resulting ratio of effective form factors for the Σ+ and Σ− is consistent with 3. In addition, ratios of the Σ+ electric and magnetic form factors, |GE/GM|, are obtained at three center-of-mass energies through an analysis of the angular distributions. These measurements, which are studied for the first time in the off-resonance region, provide precision experimental input for understanding baryonic structure. The observed new features of the Σ± form factors require more theoretical discussions for the hyperons.

Abstract: Born cross sections for the processes e+e−→ωη and e+e−→ωπ0 have been determined for center-of-mass energies between 2.00 and 3.08 GeV with the BESIII detector at the BEPCII collider. The results obtained in this work are consistent with previous measurements but with improved precision. Two resonant structures are observed. In the e+e−→ωη cross sections, a resonance with a mass of (2176±24±3)MeV/c2 and a width of (89±50±5)MeV is observed with a significance of 6.2σ. Its properties are consistent with the ϕ(2170). In the e+e−→ωπ0 cross sections, a resonance denoted Y(2040) is observed with a significance of more than 10σ. Its mass and width are determined to be (2034±13±9)MeV/c2 and (234±30±25)MeV, respectively, where the first uncertainties are statistical and the second ones are systematic.

Abstract: In Ref. [1] the BESIII collaboration published a cross section measurement of the process e+e−→π+π− in the energy range between 600 and 900 MeV. In this corrigendum, we report a corrected evaluation of the statistical errors in terms of a fully propagated covariance matrix. The correction also yields a reduced statistical uncertainty for the hadronic vacuum polarization contribution to the anomalous magnetic moment of the muon, which now reads as aμππ,LO(600−900MeV)=(368.2±1.5stat±3.3syst)×10−10. The central values of the cross section measurement and of aμππ,LO, as well as the systematic uncertainties remain unchanged.

Subjects: Environmental sciences, GE1-350
Abstract: This study focused on the distribution, combined pollution, potential source and risk assessment of 17 antibiotics in an aquaculture ecosystem surrounding the Yellow sea, North China. Antibiotics were detected in various matrices (seawater, sediment/biofilm, organism and feed) in different aquaculture modes (greenhouse and outdoor aquaculture) during the wet and dry seasons in coastal areas of Shandong province. The innovation points of the study were as follows: (1) To the best of our knowledge, this study was one of the few to investigate the occurrence and distribution of antibiotics in mariculture environments along the Yellow Sea coast; (2) Biofilms, a focus of the study, might act as a sink for antibiotics in the aquaculture ecosystem; and (3) The correlation of heavy metals and antibiotic concentrations was proved, which could correspondingly be used as an indicator for antibiotic concentrations in the studied area.The levels of antibiotics in water were observed to be relatively low, at the ng/L level. Trimethoprim was the most prevalent antibiotic, and was detected in all water samples. Oxytetracycline was detected at high concentrations in biofilms (up to 1478.29 ng/g). Moreover, biofilms exhibited a higher antibiotic accumulation capacity compared to sediments. Concentrations of oxytetracycline and doxycycline were high in feed, while other antibiotics were almost undetected. Tetracycline was widely detected and the concentration of enrofloxacin was highest in organisms.Correlation analysis demonstrated that environmental parameters and other coexisting contaminants (e.g. heavy metals) significantly affected antibiotic concentrations. In addition, the concentration of Zn was significantly correlated with the total antibiotic concentration and was proportional to several antibiotics in water and sediment (biofilm) samples (p

Abstract: We report a study of the e+e−→D+D−π+π− process using e+e− collision data samples with an integrated luminosity of 2.5fb−1 at center-of-mass energies from 4.36 to 4.60GeV, collected with the BESIII detector at the BEPCII storage ring. The D1(2420)+ is observed in the D+π+π− mass spectrum. The mass and width of the D1(2420)+ are measured to be (2427.2±1.0stat.±1.2syst.)MeV/c2 and (23.2±2.3stat.±2.3syst.)MeV, respectively. In addition, the Born cross sections of the e+e−→D1(2420)+D−+c.c.→D+D−π+π− and e+e−→ψ(3770)π+π−→D+D−π+π− processes are measured as a function of the center-of-mass energy.

Abstract: The four decay modes D0→ϕπ0, D0→ϕη, D+→ϕπ+, and D+→ϕK+ are studied by using a data sample taken at the centre-of-mass energy s=3.773 GeV with the BESIII detector, corresponding to an integrated luminosity of 2.93 fb−1. The branching fractions of the first three decay modes are measured to be B(D0→ϕπ0)=(1.168±0.028±0.028)×10−3, B(D0→ϕη)=(1.81±0.46±0.06)×10−4, and B(D+→ϕπ+)=(5.70±0.05±0.13)×10−3, respectively, where the first uncertainties are statistical and the second are systematic. In addition, the upper limit of the branching fraction for D+→ϕK+ is given to be 2.1×10−5 at the 90% confidence level. The ratio of B(D0→ϕπ0) to B(D+→ϕπ+) is calculated to be (20.49±0.50±0.45)%, which is consistent with the theoretical prediction based on isospin symmetry between these two decay modes.

Abstract: We report an improved measurement of D0–D‾0 mixing and a search for CP violation in D0 decays to CP-even final states K+K− and π+π−. The measurement is based on the final Belle data sample of 976 fb−1. The results are yCP=(1.11±0.22±0.09)% and AΓ=(−0.03±0.20±0.07)%, where the first uncertainty is statistical and the second is systematic.

Abstract: A data-driven method was applied to Au+Au collisions at sNN=200 GeV made with the STAR detector at RHIC to isolate pseudorapidity distance Δη-dependent and Δη-independent correlations by using two- and four-particle azimuthal cumulant measurements. We identified a Δη-independent component of the correlation, which is dominated by anisotropic flow and flow fluctuations. It was also found to be independent of η within the measured range of pseudorapidity |η|0.7. Keywords: Heavy-ion, Flow, Nonflow

31. Study on the Fatigue Crack Growth of the 3D Surface of the Curved Steel Plate

Author: X.L. Wang and L.L. He
Subjects: Chemical engineering, TP155-156, Computer engineering. Computer hardware, TK7885-7895
Abstract: In the present study, the author researched on the fatigue crack growth of the 3D surface of the curved steel plate. The new conceptual design of the fatigue crack arrest device provides the user with flexible operating. The proposed device design consists of a handle, body, closed-circuit monitoring system assembly, nozzle, material flow nozzle, material tanks and piston assembly. The component can be repaired by laser; the laser flows to the nozzle central aperture. The curved steel plate channel outlets are around the nozzle aperture, material aligned at working focal point follow the laser beam. Presence and detection of a flaw by proximity sensor enable the repairing process. The temperature sensor enables the material flow once achieved the required set temperature. Piston assembly may follow the material flow process. These all processes are accomplished by a compact design. This novel conceptual design provides high degree of freedom to arrest the fatigue crack with simple mechanism. It demonstrates that the proposed technique alters the fatigue crack behaviour of the 3D surface of the curved steel plate with the proposed method.

Subjects: Inflammation, Lymphangiogenesis, Microvessel density, Acute colitis, VEGF-C, Medicine (General), R5-920, Biology (General), QH301-705.5
Abstract: Angiogenesis and lymphangiogenesis are thought to play a role in the pathogenesis of inflammatory bowel diseases (IBD). However, it is not understood if inflammatory lymphangiogenesis is a pathological consequence or a productive attempt to resolve the inflammation. This study investigated the effect of lymphangiogenesis on intestinal inflammation by overexpressing a lymphangiogenesis factor, vascular endothelial growth factor-C (VEGF-C), in a mouse model of acute colitis. Forty eight-week-old female C57BL/6 mice were treated with recombinant adenovirus overexpressing VEGF-C or with recombinant VEGF-C156S protein. Acute colitis was then established by exposing the mice to 5% dextran sodium sulfate (DSS) for 7 days. Mice were evaluated for disease activity index (DAI), colonic inflammatory changes, colon edema, microvessel density, lymphatic vessel density (LVD), and VEGFR-3mRNA expression in colon tissue. When acute colitis was induced in mice overexpressing VEGF-C, there was a significant increase in colonic epithelial damage, inflammatory edema, microvessel density, and neutrophil infiltration compared to control mice. These mice also exhibited increased lymphatic vessel density (73.0±3.9 vs 38.2±1.9, P

Subjects: Chemical engineering, TP155-156, Computer engineering. Computer hardware, TK7885-7895
Abstract: The analysis of the sugarcane water requirement regulation at different temporal scale can provide a basis for optimal water management. Based on the daily meteorological observation data in Yuanmou dry-hot region during 1956-2010, sugarcane water requirement and crop water surplus deficit index were estimated, and the variation characteristics were analyzed at different temporal scale. The impact of several meteorological factors on water requirement was studied by the partial correlation analysis method. The variation pattern was conducted on the data of the annual water requirement and crop water surplus deficit index by using the Mann-Kendall test. The result showed that sugarcane water requirement in dry-hot region was significantly higher than other months from June to October and less in April, May, November and December. The moisture profit and loss was comparatively large from June to December and sugarcane depended much on irrigation, but it was less in April and May and sugarcane depended less on irrigation. Sugarcane water requirement fluctuated decreasing trend in recent 55 years. Since the 1980s, water requirement and water deficit began to decrease significantly. The changes of sugarcane water requirement were primarily attributed to wind speed and sunshine hours in dry-hot region.

Abstract: We report a search for a dark photon using $14.9$~fb$^{-1}$ of $e^+e^-$ annihilation data taken at center-of-mass energies from 4.13 to 4.60~GeV with the BESIII detector operated at the BEPCII storage ring. The dark photon is assumed to be produced in the radiative annihilation process of $e^+e^-$ and to predominantly decay into light dark matter particles, which escape from the detector undetected. The mass range from 1.5 to 2.9~GeV is scanned for the dark photon candidate, and no significant signal is observed. The mass dependent upper limits at the 90$\%$ confidence level on the coupling strength parameter $\epsilon$ for a dark photon coupling with an ordinary photon vary between $1.6\times 10^{-3}$ and $5.7\times10^{-3}$., Comment: 8 pages, 3 figures

Abstract: Melon's fruit skin quality is an agriculturally important and consumer-appealing trait. To identify molecular markers associated with fruit skin qualities, including reticulation and color, a total of 1200 Insertion/Deletion (InDel) markers randomly selected from the whole genome re-sequencing data of melon were combined with bulk segregant analysis to analyze a panel of melon genetic resources presenting reticulated- and smooth-skinned fruits as well as varying fruit skin colors. Four DNA bulks, including reticulated skin DNA bulk, smoothed skin DNA bulk, green skin DNA bulk, as well as white skin and light yellow skin DNA bulks, were developed. Four DNA pools were created by combining the DNA of 12 representative plants from each DNA bulk for polymorphism analysis, and 200 polymorphic InDel markers were selected. These polymorphic markers were used to characterize typical genetic bands within each DNA bulk. Two InDel markers, MC8-52 and MC4-7, were discovered to be related to fruit surface patterning (reticulated- and smooth-skinned fruits) and fruit color (green and white–light yellow fruits), respectively. These markers offer a high degree of detection accuracy. InDel marker MC8-52 on chromosome 8 achieved detection accuracies of 78.33% and 90.56%, whereas marker MC4-7 on chromosome 4 displayed detection accuracies of 92.92% and 83.35%, respectively. However, these markers were seen as a likely means of identifying strongly related markers for these traits. Hence, a high-resolution map of genomic regions carrying them is required for the development of highly linked markers for these traits.

Abstract: Gradient boosting decision tree (GBDT) machine learning (ML) method was adopted for the first time to automatically recognize and conduct quantitative statistical analysis of boundaries in bainitic microstructure using electron back-scatter diffraction (EBSD) data. In spite of lack of large sets of EBSD data, we were successful in achieving the desired accuracy and accomplishing the objective of recognizing the boundaries. Compared with a low model accuracy of 40°) was ∼97 %, and block boundary was ∼96 %. The derived outcomes of ML were used to obtain insights into the ductile-to-brittle transition (DBTT) behavior. Interestingly, ML modeling approach suggested that DBTT was not determined by the density of high angle grain boundaries, but significantly influenced by the density of PAG and packet boundaries. The study underscores that ML has a great potential in detailed recognition of complex multi-hierarchical microstructure such as bainite and martensite and relates to material performance.

Abstract: Sound field reconstruction technology is used to provide accurate primary reference signals for active noise control systems by reconstructing the interior sound field. Traditionally, time-domain noise signal-based reconstruction modeling has certain deficiencies, such as large data volume, noise reconstruction model complexity and considerable time consumption. Hence, a novel Signal compression optimisation-based BP network for passenger head position signal reconstruction (CBHSR) algorithm is proposed. Based on compressed sensing, the proposed algorithm converts raw multi-source signals into the compressed domain to implement compressed sampling. The signal reconstruction model is created by regarding the optimal fitness value as the initial weight and the threshold of the signal reconstruction BP network, and training with the compressed multi-source data. The recovery compression signal method realizes the time-domain signal reconstruction of the passenger head position. The effectiveness of the proposed CBHSR algorithm is validated using noise signal sources collected from a vehicle. Compared with the reconstruction model of the BP algorithm, the proposed algorithm is superior in reconstruction accuracy and time consumption.

Subjects: Chemistry, viruses, fungi, food and beverages, Mechanism (sociology), Cell biology
Abstract: Beet black scorch virus (BBSV) has been reported as a natural pathogen of sugar beet and distributed all over the world, causing great economic losses to the sugar industry. Research on interactions between BBSV and its host by using model plant Nicotiana benthamiana is significantly important and nessesary for understanding virus infection process and exploring plant resistance mechanism. The results of sequencing the transcriptome of N. benthamiana infected with BBSV as well as gene screening in response to viral infection revealed upregulation of the small heat shock protein 17.6 gene (NbHSP17.6) and the effect of the protein on resistance to the virus. To further examine the involvement of HSP17.6 in defense responses in N. benthamiana, we tested interaction between HSP17.6 and other heat shock proteins such as HSP70 and HSP90 as well as BBSV encoded proteins. The results showed that HSP17.6 interacted with HSP70 and HSP90 but not with BBSV encoded proteins. When combined with other available results, it is possible that HSP17.6 acted as a small molecular chaperone to facilitate proper refolding of the specific proteins HSP70 and HSP90 required for BBSV infection and/or replication.

Abstract: Background: Intestinal health of livestock and poultry is the basis of their body health. Different expression of growth factors is important cause of intestinal dysfunction, which further induced the illness of livestock and poultry. S-Methylmethionine Sulfonium Chloride (SMMSC) is also the main metabolite of methionine in animals. However, there are few studies exploring the relationship between SMMSC and intestinal epithelial growth factors. Methods: Piglet jejunal epithelial cells IPEC-J2 were treated with different concentrations of SMMSC at 0.1, 0.5 and 1 mM for 24 h respectively. Then real-time quantitative polymerase chain reaction (RT-qPCR) and western blotting (WB) were employed to detect the expression of Mucin-2 (MUC2), epidermal growth factor (EGF), transforming growth factor beta (TGF-β1), glucagon-like peptide-2 (GLP-2) and insulin-like growth factor-1 (IGF-1). Result: The results showed that 0.5 and 1 mM of SMMSC could stimulate the expression of MUC2, EGF, GLP-2 and IGF-1 while inhibit the expression of TGF-β1 in both mRNA and protein level (p less than 0.05). It is of great significance to repair intestinal mucosa injury, maintain intestinal mucosa barrier and promote intestinal development.

Abstract: Plasmodiophora brassicae is a biotrophic pathogen causing clubroots of cruciferous crops. The Brassica rapa accession T1-145 has an ability to produce small spheroid galls (SSGs), which represent neither a fully compatible interaction nor a complete resistance. To explore the defense response in SSGs induced by P. brassicae infection, global transcriptome profiling SSGs was performed at different time points. By comparing gene expression patterns, we identified many defense related genes. The first group included genes encoding receptor-like protein/kinases, such as cysteine-rich receptor-like protein kinases, receptor-like proteins, phloem intercalated with xylem/tracheary element differentiation inhibitory factor receptor (PXY/TDR), PXY-correlated 1, wall-associated kinases, nuclear shuttle protein-interacting kinase, lectin receptor-like kinases, and flagelin-sensitive 2, which might activate a basal defense. The second group involved robust effector-triggered immunity response genes such as resistance to leptosphaeria maculans 1B, constitutive shade-avoidance 1, target of avirulence B operation 1, ribosomal protein of the small subunit 6, resistance to Pseudomonas maculicola 1-interacting protein 4, enhanced disease resistance 2L, and recognition of Peronospora parasitica 13-like protein 4. The third group included genes encoding secondary cell wall formation related protein/s, a nodulin-like protein, a germin-like protein, a jacalin-related lectin, a defensin-like protein, tumor inhibitors, and sugars will eventually be exported transporter, which might contribute to quantitative resistance against P. brassicae. The gene expressions were the highest at the late stage of infection. To our knowledge, it is the first report on exploring defense response genes during SSG occurrence by a transcriptome analysis. Our data would provide useful information to further explore molecular mechanisms of the incomplete resistance.
