1. Proteomic analysis of chloroplasts from chlorophyll-deficient melon mutant

Author: C.M. ZHAO, J.Z. CUI, X.G. LI, B.J. CHEN, R.R. JIN, and Z.Y. YU
Subjects: label-free protein quantification, photosynthetic pathways, proteome analysis, qrt-pcr., Botany, QK1-989
Abstract: We aimed to understand the molecular-level changes occurring in the photosynthetic metabolic network in mutant chloro-plasts. We performed comparative liquid chromatography-mass spectrometry protein profiling of wild-type (WT) and chlorophyll-deficient melon (Cucumis melo L.) mutants. We identified 390 differentially expressed proteins and 81 shared proteins varied significantly in abundance, of which 76 were upregulated and 5 were downregulated. Differentially expressed proteins were involved in the following biological processes: binding, catalytic, structural, transporter, and antioxidant activities. The mutant had 6.08-fold higher expression of glutamate-1-semialdehyde 2,1-aminomutase (GSAM), an enzyme that synthesizes the chlorophyll precursor, 5-aminolevulinic acid, and a 5.02-fold higher expression of pyridoxal biosynthesis protein, a GSAM coenzyme. An RNA recognition motif-containing protein (RRM) decreased in expression by 5.22-fold. This suggests that GSAM and RRM are particularly relevant to chlorophyll deficiency.

2. Photoprotection in heteromorphic leaves of savin juniper (Juniperus sabina L.)

Author: J.L. ZHANG, X.H. XU, X.G. LI, Y.L. LI, R.D. GUY, and H.P. CHEN
Subjects: gas exchange, leaf morphology, photoinhibition, sabina vulgaris ant., water-use efficiency., Botany, QK1-989
Abstract: Savin juniper has green, photosynthetic branchlets with scale and/or needle leaves and these heteromorphic forms may contribute differentially to its success in open, arid environments. To test differences in photoprotection between fully sun-exposed scale-holding branchlets (SHB) and needle-holding branchlets (NHB), we measured gas exchange, chlorophyll (Chl) fluorescence, and pigment concentrations. NHB had higher net photosynthetic rate, stomatal conductance, and intrinsic water-use efficiency. In contrast, SHB had higher nonphotochemical quenching. Chl a, Chl b, and antheraxanthin concentrations were higher in NHB. SHB had higher zeaxanthin, lutein, and carotenoids (Car), and higher Chl a/b, Car/Chl, and α-carotene/β-carotene ratios. The results indicate greater engagement of xanthophyll-based thermal dissipation in SHB. Branchlet types acclimate to strong light using different strategies; SHB by investing in photoprotective mechanisms, and NHB by having a high photosynthetic capacity. Heterophylly may allow savin juniper to be more functionally flexible under variable environmental conditions.

Abstract: Magnetic anisotropy plays an important role in determining the magnetic functionality of thin film based electronic devices. We present here, the first systematic study of the correlation between magnetoresistance (MR) response in organic spin valves (OSVs) and magnetic anisotropy of the bottom ferromagnetic electrode over a wide temperature range (10 K–350 K). The magnetic anisotropy of a La0.67Sr0.33MnO3 (LSMO) film epitaxially grown on a SrTiO3 (STO) substrate was manipulated by reducing film thickness from 200 nm to 20 nm. Substrate-induced compressive strain was shown to drastically increase the bulk in-plane magnetic anisotropy when the LSMO became thinner. In contrast, the MR response of LSMO/OSC/Co OSVs for many organic semiconductors (OSCs) does not depend on either the in-plane magnetic anisotropy of the LSMO electrodes or their bulk magnetization. All the studied OSV devices show a similar temperature dependence of MR, indicating a similar temperature-dependent spinterface effect irrespective of LSMO thickness, resulting from the orbital hybridization of carriers at the OSC/LSMO interface.

5. Effect of different water supply on accumulation of high molecular weight glutenin subunits and glutenin macropolymers in near-isogenic wheat lines

Subjects: triticum aestivum, quality of wheat, flour, synthesis of glutenin, polymerization, Plant culture, SB1-1110
Abstract: Accumulations of high molecular weight glutenin subunits (HMW-GS) and glutenin macropolymer (GMP) in wheat grains are important indicators of grain quality. Two near-isogenic wheat lines, Line 11 (HMW-GS null, 7 + 9, 5 + 10) and Line 12 (HMW-GS null, 17 + 18, 5 + 10), were used to evaluate the impacts of different water supply on HMW-GS and GMP accumulation, and the GMP particle distributions in the grains. Three irrigation levels were implemented in a field and a pot experiment, respectively. Results indicated that drought is beneficial for grain desiccation in the two wheat lines at late filling stage. Compared to mild and excess watering, the total HMW-GS concentration at maturity was much lower when subjected to soil water deficit. Both drought and excess watering led to a reduced glutenin particle size and GMP content at maturity, indicating that a mild water supply could promote the accumulation of GMP and formation of lager glutenin particles. As opposed to Line 12, Line 11 showed an increase in accumulation of GMP and larger glutenin polymers.

6. Effect of solution treatment on pitting behavior of 2205 duplex stainless steel

Author: H. Luo, X.G. Li, C.F. Dong, and K. Xiao
Subjects: Heat treatments, Duplex stainless steel, SECM, Pitting, Chemistry, QD1-999
Abstract: The effect of solution heat treatment on pitting behavior of 2205 duplex stainless steel was investigated by EDS, potentiodynamic polarization and SECM. The contrast experiments were carried out on the original steel. The results demonstrate that for the original sample, when the potential was at the open circuit potential, there were many pitting precursor areas, due to the local breakdown of passive film on the surface, the pitting current fluctuations on the scale of pA. On the contrary, after 1100 °C solution treatment, the passive film was more stable than the original one. Therefore, the solution treatment can markedly improve the pitting resistance of 2205 duplex stainless steel due to the reduction of pitting precursor areas.

Abstract: The epithelium is a highly dynamic system, which plays a crucial role in the homeostasis of the intestinal tract. However, studies on the physiological and pathophysiological functions of intestinal epithelial cells (IECs) have been hampered due to lack of normal epithelial cell models. In the present study, we established a reproducible method for primary culture of mouse IECs, which were isolated from the viable small intestinal crypts of murine fetuses (on embryonic day 19), using type I collagenase and hyaluronidase in a short span of time (≤20 min). With this method, continuously growing mouse IECs, which can be subcultured over a number of passages, were obtained. The obtained cell lines formed a tight cobblestone-like arrangement, displayed long and slender microvilli, expressed characteristic markers (cytokeratin 18 and Notch-1), and generated increasing transepithelial electrical resistance and low paracellular permeability during in vitro culture. The cells also had enzymatic activities of alkaline phosphatase and sucrase-isomaltase, and secreted various cytokines (IL-1β, IL-6, IL-8, and monocyte chemoattractant protein-1), responding to the stimulation of Escherichia coli. These results show that the primary-cultured mouse IECs obtained by the method established here had the morphological and immunological characteristics of IECs. This culture system can be a beneficial in vitro model for studies on mucosal immunology and toxicology.

The measurements are fully corrected for detector effects, and reported differentially in both the jet transverse momentum and jet radius parameter. We compare the measurements to established leading-order Monte Carlo event generators and find that STAR-tuned pythia-6 reproduces the data, while LHC tunes of pythia-8 and herwig-7 do not agree with the data, providing further constraints on parameter tuning. Finally, we observe that softdrop grooming, for which the contribution of wide-angle nonperturbative radiation is suppressed, shifts the jet mass distributions into closer agreement with the partonic jet mass as determined by both pythia-8 and a next-to-leading-logarithmic accuracy perturbative QCD calculation. These measurements complement recent LHC measurements in a different kinematic region, as well as establish a baseline for future jet mass measurements in heavy-ion collisions at RHIC.

The Cn and κn are presented as a function of collision energy, centrality and kinematic acceptance in rapidity, y, and transverse momentum, pT. The data were taken during the first phase of the Beam Energy Scan (BES) program (2010-2017) at the BNL Relativistic Heavy Ion Collider (RHIC) facility. The measurements are carried out at midrapidity (|y|l 0.5) and transverse momentum 0.4

Transverse momentum (pT) dependence of flow coefficients (v2, v3, and v4) is presented for minimum bias collisions and three different centrality intervals. Number of constituent quark scaling of the measured flow coefficients in U+U collisions is discussed. We also present the ratio of vn scaled by the participant eccentricity (ɛn2) to explore system size dependence and collectivity in U+U collisions. The magnitude of v2/ɛ2 is found to be smaller in U+U collisions than that in central Au+Au collisions contradicting naive eccentricity scaling. Furthermore, the ratios between various flow harmonics (v3/v23/2, v4/v24/2) are studied and compared with hydrodynamic and transport model calculations.

The new inclusive jet data are sensitive to the gluon helicity distribution, Δg(x,Q2), for gluon momentum fractions in the range from x≃0.05 to x≃0.5, while the new dijet data provide further constraints on the x dependence of Δg(x,Q2). The results are in good agreement with previous measurements at s=200 GeV and with recent theoretical evaluations of prior world data. Our new results have better precision and thus strengthen the evidence that Δg(x,Q2) is positive for xg0.05.

Neutral pions are observed in the forward direction relative to the transversely polarized proton beam, in the pseudorapidity region 2.7lηl3.8. Results are presented for π0s observed in the STAR forward meson spectrometer electromagnetic calorimeter in narrow Feynman x (xF) and transverse momentum (pT) bins, spanning the range 0.172.5 GeV/c. It is further observed that the value of AN is significantly larger for events with a large-pT isolated π0 than for events with a nonisolated π0 accompanied by additional jetlike fragments. The nuclear dependence r(A) is similar for isolated and nonisolated π0 events.

Abstract: We aimed to understand the molecular-level changes occurring in the photosynthetic metabolic network in mutant chloro-plasts. We performed comparative liquid chromatography-mass spectrometry protein profiling of wild-type (WT) and chlorophyll-deficient melon (Cucumis melo L.) mutants. We identified 390 differentially expressed proteins and 81 shared proteins varied significantly in abundance, of which 76 were upregulated and 5 were downregulated. Differentially expressed proteins were involved in the following biological processes: binding, catalytic, structural, transporter, and antioxidant activities. The mutant had 6.08-fold higher expression of glutamate-1-semialdehyde 2,1-aminomutase (GSAM), an enzyme that synthesizes the chlorophyll precursor, 5-aminolevulinic acid, and a 5.02-fold higher expression of pyridoxal biosynthesis protein, a GSAM coenzyme. An RNA recognition motif-containing protein (RRM) decreased in expression by 5.22-fold. This suggests that GSAM and RRM are particularly relevant to chlorophyll deficiency.

Abstract: Savin juniper has green, photosynthetic branchlets with scale and/or needle leaves and these heteromorphic forms may contribute differentially to its success in open, arid environments. To test differences in photoprotection between fully sun-exposed scale-holding branchlets (SHB) and needle-holding branchlets (NHB), we measured gas exchange, chlorophyll (Chl) fluorescence, and pigment concentrations. NHB had higher net photosynthetic rate, stomatal conductance, and intrinsic water-use efficiency. In contrast, SHB had higher nonphotochemical quenching. Chl a, Chl b, and antheraxanthin concentrations were higher in NHB. SHB had higher zeaxanthin, lutein, and carotenoids (Car), and higher Chl a/b, Car/Chl, and α-carotene/β-carotene ratios. The results indicate greater engagement of xanthophyll-based thermal dissipation in SHB. Branchlet types acclimate to strong light using different strategies; SHB by investing in photoprotective mechanisms, and NHB by having a high photosynthetic capacity. Heterophylly may allow savin juniper to be more functionally flexible under variable environmental conditions.

Abstract: We present the first measurement of the proton–Ω correlation function in heavy-ion collisions for the central (0–40%) and peripheral (40–80%) Au + Au collisions at s NN = 200 GeV by the STAR experiment at the Relativistic Heavy-Ion Collider (RHIC). Predictions for the ratio of peripheral collisions to central collisions for the proton–Ω correlation function are sensitive to the presence of a nucleon–Ω bound state. These predictions are based on the proton–Ω interaction extracted from ( 2 + 1 ) -flavor lattice QCD calculations at the physical point. The measured ratio of the proton–Ω correlation function between the peripheral (small system) and central (large system) collisions is less than unity for relative momentum smaller than 40 MeV/c. Comparison of our measured correlation ratio with theoretical calculation slightly favors a proton–Ω bound system with a binding energy of ∼ 27 MeV.

Abstract: The beam energy scan (BES) program at the BNL Relativistic Heavy Ion Collider (RHIC) was extended to energies below sNN=7.7 GeV in 2015 by successful implementation of the fixed-target mode of operation in the STAR (Solenoidal Tracker At RHIC) experiment. In this mode, ions circulate in one ring of the collider and interact with a stationary target at the entrance of the STAR time projection chamber. The first results for Au+Au collisions at sNN=4.5 GeV are presented, demonstrating good performance of all the relevant detector subsystems in fixed-target mode. Results presented here include directed and elliptic flow of identified hadrons, and radii from pion femtoscopy. The latter, together with recent HADES results, reveal a long-sought peak structure that may be caused by the system evolving through a first-order phase transition from quark-gluon plasma to the hadronic phase. Directed and elliptic flow for pions are presented for the first time at this beam energy. Pion and proton elliptic flow show behavior which hints at constituent quark scaling, and demonstrate that a definitive conclusion will be achievable using the full statistics of the ongoing second phase of BES (BES-II). In particular, BES-II to date has recorded fixed-target data sets with two orders of magnitude more events at each of nine energies between sNN=3.0 and 7.7 GeV.

The cross sections and their ratios are sensitive to quark and antiquark parton distribution functions. In particular, at leading order, the W cross section ratio is sensitive to the d¯/ū ratio. These measurements were taken at high Q2∼MW2,MZ2 and can serve as input into global analyses to provide constraints on the sea quark distributions. The results presented here combine three STAR datasets from 2011, 2012, and 2013, accumulating an integrated luminosity of 350 pb-1. We also assess the expected impact that our W+/W- cross section ratios will have on various quark distributions, and find sensitivity to the ū-d¯ and d¯/ū distributions.

The polarization parameters, λθ, λφ, and λθφ, are measured as a function of transverse momentum (pT) in both the helicity and Collins-Soper (CS) reference frames within pTl10 GeV/c. Except for λθ in the CS frame at the highest measured pT, all three polarization parameters are consistent with 0 in both reference frames without any strong pT dependence. Several model calculations are compared with data, and the one using the Color Glass Condensate effective field theory coupled with nonrelativistic QCD gives the best overall description of the experimental results, even though other models cannot be ruled out due to experimental uncertainties.

Abstract: The measurements of particle multiplicity distributions have generated considerable interest in understanding the fluctuations of conserved quantum numbers in the quantum chromodynamics (QCD) hadronization regime, in particular near a possible critical point and near the chemical freeze-out. Net-protons and net-kaons have been used as proxies for the net-baryon number and net-strangeness, respectively. We report the measurement of efficiency- and centrality-bin width-corrected cumulant ratios (C2/C1, C3/C2) of net-Λ distributions, in the context of both strangeness and baryon number conservation, as a function of collision energy, centrality, and rapidity. The results are for Au+Au collisions at five beam energies (sNN=19.6, 27, 39, 62.4, and 200 GeV) recorded with the Solenoidal Tracker at RHIC (STAR). We compare our results to the Poisson and negative binomial (NBD) expectations, as well as to ultrarelativistic quantum molecular dynamics (UrQMD) and hadron resonance gas (HRG) model predictions. Both NBD and Poisson baselines agree with data within the statistical and systematic uncertainties. UrQMD describes the measured net-ΛC1 and C3 at 200 GeV reasonably well but deviates from C2, and the deviation increases as a function of collision energy. The ratios of the measured cumulants show no features of critical fluctuations. The chemical freeze-out temperatures extracted from a recent HRG calculation, which was successfully used to describe the net-proton, net-kaon, and net-charge data, indicate Λ freeze-out conditions similar to those of kaons. However, large deviations are found when comparing with temperatures obtained from net-proton fluctuations. The net-Λ cumulants show a weak but finite dependence on the rapidity coverage in the acceptance of the detector, which can be attributed to quantum number conservation.

These correlations were measured for both like-sign and unlike-sign charge combinations and versus the centrality. The correlations of pions and kaons show the expected near-side ({\it i.e.}, at small relative angles) peak resulting from short-range mechanisms. The amplitudes of these short-range correlations decrease with increasing beam energy. However, the proton correlation functions exhibit strong anticorrelations in the near-side region. This behavior is observed for the first time in an A+A collision system. The observed anticorrelation is $p_{T}$-independent and decreases with increasing beam energy and centrality. The experimental results are also compared to the Monte Carlo models UrQMD, Hijing, and AMPT.

Abstract: The effects of Ca doping on the Curie temperature, structural, dielectric and elastic properties of Ba0.4Sr0.6-xCaxTiO3 (0 less than or equal to x less than or equal to 0.3) was studied. It was found that Ca doping induces that hardening of C(sub L) just below T(sub C) and the magnitude of the relative hardening of C(sub L) increases with increasing x, implying that the tetragonal ferroelectric phase was increasingly stabilized by Ca doping.

Abstract: A vibration sensor based on Sagnac interferometer and fiber ring laser (FRL) is proposed for fault diagnosis of bearing, and a sensing system of vibration is demonstrated experimentally. In the sensing system, the Sagnac interferometer based on single mode fiber- polarization maintaining fiber-single mode fiber (SPS) as a sensor is connected to FRL which performs as a filter. Because the transmission characteristics of the SPS is modulated by strain, intensity-modulated sensing is induced for output power of the FRL. Experimental result shows that the accurate frequency of the vibration signal within relative error of 1.0% can be obtained by the sensor. The proposed sensor has the advantages of low-cost, compact size, easy to be fabricated and excellent anti-interference ability, which has potential applications on the bearing fault diagnosis of rotating machinery.

Abstract: Magnetic anisotropy plays an important role in determining the magnetic functionality of thin film based electronic devices. We present here, the first systematic study of the correlation between magnetoresistance (MR) response in organic spin valves (OSVs) and magnetic anisotropy of the bottom ferromagnetic electrode over a wide temperature range (10 K–350 K). The magnetic anisotropy of a La0.67Sr0.33MnO3 (LSMO) film epitaxially grown on a SrTiO3 (STO) substrate was manipulated by reducing film thickness from 200 nm to 20 nm. Substrate-induced compressive strain was shown to drastically increase the bulk in-plane magnetic anisotropy when the LSMO became thinner. In contrast, the MR response of LSMO/OSC/Co OSVs for many organic semiconductors (OSCs) does not depend on either the in-plane magnetic anisotropy of the LSMO electrodes or their bulk magnetization. All the studied OSV devices show a similar temperature dependence of MR, indicating a similar temperature-dependent spinterface effect irrespective of LSMO thickness, resulting from the orbital hybridization of carriers at the OSC/LSMO interface.

Abstract: The Λ (Λ[over ¯]) hyperon polarization along the beam direction has been measured in Au+Au collisions at sqrt[s_{NN}]=200 GeV, for the first time in heavy-ion collisions. The polarization dependence on the hyperons' emission angle relative to the elliptic flow plane exhibits a second harmonic sine modulation, indicating a quadrupole pattern of the vorticity component along the beam direction, expected due to elliptic flow. The polarization is found to increase in more peripheral collisions, and shows no strong transverse momentum (p_{T}) dependence at p_{T} greater than 1 GeV/c. The magnitude of the signal is about 5 times smaller than those predicted by hydrodynamic and multiphase transport models; the observed phase of the emission angle dependence is also opposite to these model predictions. In contrast, the kinematic vorticity calculations in the blast-wave model tuned to reproduce particle spectra, elliptic flow, and the azimuthal dependence of the Gaussian source radii measured with the Hanbury Brown-Twiss intensity interferometry technique reproduce well the modulation phase measured in the data and capture the centrality and transverse momentum dependence of the polarization signal.

Abstract: We report the first measurement of the inclusive jet and the dijet longitudinal double-spin asymmetries, ALL, at midrapidity in polarized pp collisions at a center-of-mass energy s=510 GeV. The inclusive jet ALL measurement is sensitive to the gluon helicity distribution down to a gluon momentum fraction of x≈0.015, while the dijet measurements, separated into four jet-pair topologies, provide constraints on the x dependence of the gluon polarization. Both results are consistent with previous measurements made at s=200 GeV in the overlapping kinematic region, x>0.05, and show good agreement with predictions from recent next-to-leading order global analyses.

Invariant yields of D0 mesons with transverse momentum pT9GeV/c are reported in various centrality bins (0-10%, 10-20%, 20-40%, 40-60%, and 60-80%). Blast-wave thermal models are used to fit the D0-meson pT spectra to study D0 hadron kinetic freeze-out properties. The average radial flow velocity extracted from the fit is considerably smaller than that of light hadrons (π,K, and p), but comparable to that of hadrons containing multiple strange quarks (φ,Ξ-), indicating that D0 mesons kinetically decouple from the system earlier than light hadrons. The calculated D0 nuclear modification factors reaffirm that charm quarks suffer a large amount of energy loss in the medium, similar to those of light quarks for pTg4GeV/c in central 0-10% Au + Au collisions. At low pT, the nuclear modification factors show a characteristic structure qualitatively consistent with the expectation from model predictions that charm quarks gain sizable collective motion during the medium evolution. The improved measurements are expected to offer new constraints to model calculations and help gain further insights into the hot and dense medium created in these collisions.

Abstract: In 2018, the STAR collaboration collected data from $$_{44}^{96}{\mathrm{Ru}}+_{44}^{96}{\mathrm{Ru}}$$ and $$_{40}^{96}{\mathrm{Zr}}+_{40}^{96}{\mathrm{Zr}}$$ at $$\sqrt{s_\text {NN}}=200$$ GeV to search for the presence of the chiral magnetic effect in collisions of nuclei. The isobar collision species alternated frequently between $$_{44}^{96}{\mathrm{Ru}}+_{44}^{96}{\mathrm{Ru}}$$ and $$_{40}^{96}{\mathrm{Zr}}+_{40}^{96}{\mathrm{Zr}}$$ . In order to conduct blind analyses of studies related to the chiral magnetic effect in these isobar data, STAR developed a three-step blind analysis procedure. Analysts are initially provided a “reference sample” of data, comprised of a mix of events from the two species, the order of which respects time-dependent changes in run conditions. After tuning analysis codes and performing time-dependent quality assurance on the reference sample, analysts are provided a species-blind sample suitable for calculating efficiencies and corrections for individual $$\approx 30$$ -min data-taking runs. For this sample, species-specific information is disguised, but individual output files contain data from a single isobar species. Only run-by-run corrections and code alteration subsequent to these corrections are allowed at this stage. Following these modifications, the “frozen” code is passed over the fully un-blind data, completing the blind analysis. As a check of the feasibility of the blind analysis procedure, analysts completed a “mock data challenge,” analyzing data from $${\mathrm{Au}}+{\mathrm{Au}}$$ collisions at $$\sqrt{s_\text {NN}}=27$$ GeV, collected in 2018. The $${\mathrm{Au}}+{\mathrm{Au}}$$ data were prepared in the same manner intended for the isobar blind data. The details of the blind analysis procedure and results from the mock data challenge are presented.

Abstract: Crystal rotation of the orientation-preferred Cu6Sn5 formed on (001)Cu usually happens in soldering, and its rotation rate depends on the temperature closely. In this work, the evolutions of intermetallic orientation, phase and thickness at Sn-3.0Ag/(001)Cu interface were systematically investigated under temperatures of 230 °C, 250 °C and 300 °C. Results illustrate that the nucleation of orientation-preferred Cu6Sn5 on (001)Cu can be realized at any temperature above the solder melting point, but subsequently crystal rotation from 2 ¯ 0 > to 〈0001〉 in ND happens as well. High temperature was found to greatly maintain the initial orientation of Cu6Sn5 crystals as well as facilitate the formation and growth of Cu3Sn, which can effectively reduce the driving force of Cu6Sn5 rotation and consequently inhibiting the rotation of Cu6Sn5 crystals. Finally, a theoretical model of Cu6Sn5 crystal rotation based on interfacial thermodynamic calculation was established and a two time reflow profile of 300 °C–230 °C was designed to furthest inhibit the rotation of Cu6Sn5 crystals and maintain the preferred orientation of Cu6Sn5 texture according to our proposed theory. The results are of great significance for the intermetallic orientation control in soldering.

Abstract: In this letter, measurements of the shared momentum fraction ( z g ) and the groomed jet radius ( R g ), as defined in the SoftDrop algorithm, are reported in p+p collisions at s = 200 GeV collected by the STAR experiment. These substructure observables are differentially measured for jets of varying resolution parameters from R = 0.2 − 0.6 in the transverse momentum range 15 p T , jet 60 GeV/c. These studies show that, in the p T , jet range accessible at s = 200 GeV and with increasing jet resolution parameter and jet transverse momentum, the z g distribution asymptotically converges to the DGLAP splitting kernel for a quark radiating a gluon. The groomed jet radius measurements reflect a momentum-dependent narrowing of the jet structure for jets of a given resolution parameter, i.e., the larger the p T , jet , the narrower the first splitting. For the first time, these fully corrected measurements are compared to Monte Carlo generators with leading order QCD matrix elements and leading log in the parton shower, and to state-of-the-art theoretical calculations at next-to-leading-log accuracy. We observe that PYTHIA 6 with parameters tuned to reproduce RHIC measurements is able to quantitatively describe data, whereas PYTHIA 8 and HERWIG 7, tuned to reproduce LHC data, are unable to provide a simultaneous description of both z g and R g , resulting in opportunities for fine parameter tuning of these models for p+p collisions at RHIC energies. We also find that the theoretical calculations without non-perturbative corrections are able to qualitatively describe the trend in data for jets of large resolution parameters at high p T , jet , but fail at small jet resolution parameters and low jet transverse momenta.

Abstract: Accumulations of high molecular weight glutenin subunits (HMW-GS) and glutenin macropolymer (GMP) in wheat grains are important indicators of grain quality. Two near-isogenic wheat lines, Line 11 (HMW-GS null, 7 + 9, 5 + 10) and Line 12 (HMW-GS null, 17 + 18, 5 + 10), were used to evaluate the impacts of different water supply on HMW-GS and GMP accumulation, and the GMP particle distributions in the grains. Three irrigation levels were implemented in a field and a pot experiment, respectively. Results indicated that drought is beneficial for grain desiccation in the two wheat lines at late filling stage. Compared to mild and excess watering, the total HMW-GS concentration at maturity was much lower when subjected to soil water deficit. Both drought and excess watering led to a reduced glutenin particle size and GMP content at maturity, indicating that a mild water supply could promote the accumulation of GMP and formation of lager glutenin particles. As opposed to Line 12, Line 11 showed an increase in accumulation of GMP and larger glutenin polymers.

Abstract: Orientation-preferred Cu6Sn5 usually offers solder interconnections superior mechanical and physical performances. In this work, morphology and orientation evolutions of Cu6Sn5 at Sn-3.0Ag/(001)Cu interface were investigated in the 300 °C–300 °C, 230 °C–230 °C and 300 °C–230 °C reflow processes. Results demonstrated that the continuous growth of orientation-preferred Cu6Sn5 was realized in the temperature-decreased reflow process of 300 °C–230 °C and the fraction of 0° boundaries in preferred Cu6Sn5 decreased from 0.81 to 0.60 with time while the fraction of 90° boundaries increased from 0.19 to 0.40; both curvature difference and misorientation angle of grain boundaries should be valued in the growth of preferred Cu6Sn5; the coarsening of preferred Cu6Sn5 includes two methods: coalescence and annexation, induced by the disappearance and migration of grain boundaries respectively. These results are of great significance in the orientation and size control of Cu6Sn5 crystals in 3D packaging.

Abstract: We present a study of charm and beauty isolation based on a data-driven method with recent measurements on heavy flavor hadrons and their decay electrons in Au+Au collisions at s NN = 200 GeV at RHIC. The individual electron p T spectra, R AA and v 2 distributions from charmed and beauty hadron decays are obtained. We find that the electron R AA from beauty hadron decays ( R AA b → e ) is suppressed in minimum bias Au+Au collisions but less suppressed compared with that from charmed hadron decays at p T > 3.5 GeV/c, which indicates that beauty quark interacts with the hot-dense medium with depositing its energy and is consistent with the mass-dependent energy loss scenario. For the first time, the non-zero electron v 2 from beauty hadron decays ( v 2 b → e ) at p T > 3.0 GeV/c is observed and shows smaller elliptic flow compared with that from charmed hadron decays at p T p T v 2 b → e is smaller than a number-of-constituent-quark (NCQ) scaling hypothesis. This suggests that beauty quark is unlikely thermalized and too heavy to be moved in a partonic collectivity in heavy-ion collisions at the RHIC energy.

The dijets were measured in polarized pp collisions at a center-of-mass energy s=200 GeV. Values for ALL are determined for several distinct event topologies, defined by the jet pseudorapidities, and span a range of parton momentum fraction x down to x∼0.01. The measured asymmetries are found to be consistent with the predictions of global analyses that incorporate the results of previous RHIC measurements. They will provide new constraints on Δg(x) in this poorly constrained region when included in future global analyses.

Abstract: We report measurements of the nuclear modification factor R_{CP} for charged hadrons as well as identified π^{+(-)}, K^{+(-)}, and p(p[over ¯]) for Au+Au collision energies of sqrt[s_{NN}]=7.7, 11.5, 14.5, 19.6, 27, 39, and 62.4 GeV. We observe a clear high-p_{T} net suppression in central collisions at 62.4 GeV for charged hadrons which evolves smoothly to a large net enhancement at lower energies. This trend is driven by the evolution of the pion spectra but is also very similar for the kaon spectra. While the magnitude of the proton R_{CP} at high p_{T} does depend on the collision energy, neither the proton nor the antiproton R_{CP} at high p_{T} exhibit net suppression at any energy. A study of how the binary collision-scaled high-p_{T} yield evolves with centrality reveals a nonmonotonic shape that is consistent with the idea that jet quenching is increasing faster than the combined phenomena that lead to enhancement.

In this paper, the mesonic decay modes HΛ3→He3 + π- and HΛ3→d+p+π- are used to reconstruct the HΛ3 from Au+Au collision data collected by the STAR collaboration at Relativistic Heavy Ion Collider (RHIC). A minimum χ2 estimation is used to determine the lifetime of τ=142-21+24(stat.)±29(syst.) ps. This lifetime is about 50% shorter than the lifetime τ=263±2 ps of a free Λ, indicating strong hyperon-nucleon interaction in the hypernucleus system. The branching ratios of the mesonic decay channels are also determined to satisfy B.R.(He3+π-)/(B.R.(He3+π-)+B.R.(d+p+π-))=0.32±0.05(stat.)±0.08(syst.). Our ratio result favors the assignment J(HΛ3)=12 over J(HΛ3)=32. These measurements will help to constrain models of hyperon-baryon interactions.
