Lanthanum (La) has been used as agricultural inputs in order to enhance yield and improve crop quality. However, little is known about the effect of La on the photosynthesis and growth of Amorphophallus sinensis, a worldwide food source. The effects of La on the photosynthetic and chlorophyll fluorescence parameters, photosynthetic pigments, corm yield, and konjac glucomannan (KGM) of Amorphophallus sinensis were investigated via field experiments. The leaves were sprayed with different concentrations of LaCl3 (20, 80, 160, and 240 mg L-1). The results exhibited an increasing effect of LaCl3 on photosynthetic rate, stomatal conductance, intercellular CO2 concentration, chlorophyll fluorescence parameters, photosynthetic pigments, corm yield, and KGM, when concentration was between 20 and 240 mg L-1, and the most effective concentration was 160 mg L-1. Therefore, moderate LaCl3 concentration may increase yield of Amorphophallus sinensis by enhancing the photosynthetic efficiency, increasing the corm yield, and KGM contents.

Physics ,QC1-999 - Abstract
Using 16 energy points of e+e− annihilation data collected in the vicinity of the J/ψ resonance with the BESIII detector and with a total integrated luminosity of around 100pb−1, we study the relative phase between the strong and electromagnetic amplitudes of J/ψ decays. The relative phase between J/ψ electromagnetic decay and the continuum process (e+e− annihilation without the J/ψ resonance) is confirmed to be zero by studying the cross section lineshape of μ+μ− production. The relative phase between J/ψ strong and electromagnetic decays is then measured to be (84.9±3.6)∘ or (−84.7±3.1)∘ for the 2(π+π−)π0 final state by investigating the interference pattern between the J/ψ decay and the continuum process. This is the first measurement of the relative phase between J/ψ strong and electromagnetic decays into a multihadron final state using the lineshape of the production cross section. We also study the production lineshape of the multihadron final state ηπ+π− with η→π+π−π0, which provides additional information about the phase between the J/ψ electromagnetic decay amplitude and the continuum process. Additionally, the branching fraction of J/ψ→2(π+π−)π0 is measured to be (4.73±0.44)% or (4.85±0.45)%, and the branching fraction of J/ψ→ηπ+π− is measured to be (3.78±0.68)×10−4. Both of them are consistent with the world average values. The quoted uncertainties include both statistical and systematic uncertainties, which are mainly caused by the low statistics. Keywords: Phase, Strong amplitude, Electromagnetic amplitude, J/ψ decay, BESIII

Physics ,QC1-999 - 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.

Physics ,QC1-999 - Abstract
Using a data sample of e+e− collision data corresponding to an integrated luminosity of 2.93 fb−1 collected with the BESIII detector at a center-of-mass energy of s=3.773GeV, we search for the singly Cabibbo-suppressed decays D0→π0π0π0, π0π0η, π0ηη and ηηη using the double tag method. The absolute branching fractions are measured to be B(D0→π0π0π0)=(2.0±0.4±0.3)×10−4, B(D0→π0π0η)=(3.8±1.1±0.7)×10−4 and B(D0→π0ηη)=(7.3±1.6±1.5)×10−4 with the statistical significances of 4.8σ, 3.8σ and 5.5σ, respectively, where the first uncertainties are statistical and the second ones systematic. No significant signal of D0→ηηη is found, and the upper limit on its decay branching fraction is set to be B(D0→ηηη)

Abstract Introduction There is conflicting evidence whether high‐density lipoprotein cholesterol (HDL‐C) is a risk factor for Alzheimer's disease (AD) and dementia. Genetic variation in the cholesteryl ester transfer protein (CETP) locus is associated with altered HDL‐C. We aimed to assess AD risk by genetically predicted HDL‐C. Methods Ten single nucleotide polymorphisms within the CETP locus predicting HDL‐C were applied to the International Genomics of Alzheimer's Project (IGAP) exome chip stage 1 results in up 16,097 late onset AD cases and 18,077 cognitively normal elderly controls. We performed instrumental variables analysis using inverse variance weighting, weighted median, and MR‐Egger. Results Based on 10 single nucleotide polymorphisms distinctly predicting HDL‐C in the CETP locus, we found that HDL‐C was not associated with risk of AD (P > .7). Discussion Our study does not support the role of HDL‐C on risk of AD through HDL‐C altered by CETP. This study does not rule out other mechanisms by which HDL‐C affects risk of AD.

Dark photon search ,Initial state radiation ,BESIII ,Physics ,QC1-999 - Abstract
Using a data set of 2.93 fb−1 taken at a center-of-mass energy s=3.773 GeV with the BESIII detector at the BEPCII collider, we perform a search for an extra U(1) gauge boson, also denoted as a dark photon. We examine the initial state radiation reactions e+e−→e+e−γISR and e+e−→μ+μ−γISR for this search, where the dark photon would appear as an enhancement in the invariant mass distribution of the leptonic pairs. We observe no obvious enhancement in the mass range between 1.5 and 3.4 GeV/c2 and set a 90% confidence level upper limit on the mixing strength of the dark photon and the Standard Model photon. We obtain a competitive limit in the tested mass range.

e+e− annihilation ,Triple quarkonia ,Cross section ,Physics ,QC1-999 - Abstract
Using data samples collected with the BESIII detector at the BEPCII collider at six center-of-mass energies between 4.008 and 4.600 GeV, we observe the processes e+e−→ϕϕω and e+e−→ϕϕϕ. The Born cross sections are measured and the ratio of the cross sections σ(e+e−→ϕϕω)/σ(e+e−→ϕϕϕ) is estimated to be 1.75±0.22±0.19 averaged over six energy points, where the first uncertainty is statistical and the second is systematic. The results represent first measurements of these interactions.

Branching fraction ,Charmed baryon ,Weak decays ,e+e− annihilation ,BESIII ,Physics ,QC1-999 - Abstract
We report the first observation of the decay Λc+→Σ−π+π+π0, based on data obtained in e+e− annihilations with an integrated luminosity of 567 pb−1 at s=4.6 GeV. The data were collected with the BESIII detector at the BEPCII storage rings. The absolute branching fraction B(Λc+→Σ−π+π+π0) is determined to be (2.11±0.33(stat.)±0.14(syst.))%. In addition, an improved measurement of B(Λ+c→Σ−π+π+) is determined as (1.81±0.17(stat.)±0.09(syst.))%.

Physics ,QC1-999 - Abstract
Based on e+e− annihilation data samples collected with the BESIII detector at the BEPCII collider at 13 center-of-mass energies from 4.008 to 4.600 GeV, measurements of the Born cross section of e+e−→pp¯π0 are performed. No significant resonant structure is observed in the measured energy dependence of the cross section. The upper limit on the Born cross section of e+e−→Y(4260)→pp¯π0 at the 90% C.L. is determined to be 0.01 pb. The upper limit on the ratio of the branching fractions B(Y(4260)→pp¯π0)B(Y(4260)→π+π−J/ψ) at the 90% C.L. is determined to be 0.02%. Keywords: Hadrons, Cross section measurements, Y(4260)

Charmonium ,Branching fraction ,Angular distribution ,Physics ,QC1-999 - Abstract
We study the decays of J/ψ and ψ(3686) to the final states Σ(1385)0Σ¯(1385)0 and Ξ0Ξ¯0 based on a single baryon tag method using data samples of (1310.6±7.0)×106 J/ψ and (447.9±2.9)×106 ψ(3686) events collected with the BESIII detector at the BEPCII collider. The decays to Σ(1385)0Σ¯(1385)0 are observed for the first time. The measured branching fractions of J/ψ and ψ(3686) to Ξ0Ξ¯0 are in good agreement with, and much more precise than, the previously published results. The angular parameters for these decays are also measured for the first time. The measured angular decay parameter for J/ψ→Σ(1385)0Σ¯(1385)0, α=−0.64±0.03±0.10, is found to be negative, different to the other decay processes in this measurement. In addition, the “12% rule” and isospin symmetry in the decays of J/ψ and ψ(3686) to ΞΞ¯ and Σ(1385)Σ¯(1385) are tested.

Λc+ ,Semi-leptonic decay ,Absolute branching fraction ,BESIII ,Physics ,QC1-999 - Abstract
We report the first measurement of the absolute branching fraction for Λc+→Λμ+νμ. This measurement is based on a sample of e+e− annihilation data produced at a center-of-mass energy s=4.6 GeV, collected with the BESIII detector at the BEPCII storage rings. The sample corresponds to an integrated luminosity of 567 pb−1. The branching fraction is determined to be B(Λc+→Λμ+νμ)=(3.49±0.46(stat)±0.27(syst))%. In addition, we calculate the ratio B(Λc+→Λμ+νμ)/B(Λc+→Λe+νe) to be 0.96±0.16(stat)±0.04(syst).

BESIII ,D0 and D+ mesons ,Hadronic decays ,Branching fractions ,Physics ,QC1-999 - Abstract
By analyzing 2.93fb−1 of data taken at the ψ(3770) resonance peak with the BESIII detector, we measure the branching fractions for the hadronic decays D+→KS0KS0K+, D+→KS0KS0π+, D0→KS0KS0 and D0→KS0KS0KS0. They are determined to be B(D+→KS0KS0K+)=(2.54±0.05stat.±0.12sys.)×10−3, B(D+→KS0KS0π+)=(2.70±0.05stat.±0.12sys.)×10−3, B(D0→KS0KS0)=(1.67±0.11stat.±0.11sys.)×10−4 and B(D0→KS0KS0KS0)=(7.21±0.33stat.±0.44sys.)×10−4, where the second one is measured for the first time and the others are measured with significantly improved precision over the previous measurements.

Physics ,QC1-999 - 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. Keywords: BESIII, D meson, Hadronic decays, Branching fractions

Using a data set of 2.93 fb−1 taken at a center-of-mass energy of s=3.773 GeV with the BESIII detector at the BEPCII collider, we measure the process e+e−→J/ψγ→μ+μ−γ and determine the product of the branching fraction and the electronic width Bμμ⋅Γee=(333.4±2.5stat±4.4sys) eV. Using the earlier-published BESIII result for Bμμ=(5.973±0.007stat±0.037sys)%, we derive the J/ψ electronic width Γee=(5.58±0.05stat±0.08sys) keV.

Hadronic cross section ,Muon anomaly ,Initial state radiation ,Pion form factor ,BESIII ,Physics ,QC1-999 - Abstract
We extract the e+e−→π+π− cross section in the energy range between 600 and 900 MeV, exploiting the method of initial state radiation. A data set with an integrated luminosity of 2.93 fb−1 taken at a center-of-mass energy of 3.773 GeV with the BESIII detector at the BEPCII collider is used. The cross section is measured with a systematic uncertainty of 0.9%. We extract the pion form factor |Fπ|2 as well as the contribution of the measured cross section to the leading-order hadronic vacuum polarization contribution to (g−2)μ. We find this value to be aμππ,LO(600–900MeV)=(368.2±2.5stat±3.3sys)⋅10−10, which is between the corresponding values using the BaBar or KLOE data.

Physics ,QC1-999 - Abstract
By analyzing a data set of 2.92 fb−1 of e+e− collision data taken at s=3.773 GeV and 106.41×106 ψ(3686) decays taken at s=3.686 GeV with the BESIII detector at the BEPCII collider, we measure the branching fraction and the partial decay width for ψ(3770)→γχc0 to be B(ψ(3770)→γχc0)=(6.88±0.28±0.67)×10−3 and Γ[ψ(3770)→γχc0]=(187±8±19) keV, respectively. These are the most precise measurements to date.

BESIII ,Ds ,Branching fractions ,Physics ,QC1-999 - Abstract
We study Ds+ decays to final states involving the η′ with a 482 pb−1 data sample collected at s=4.009 GeV with the BESIII detector at the BEPCII collider. We measure the branching fractions B(Ds+→η′X)=(8.8±1.8±0.5)% and B(Ds+→η′ρ+)=(5.8±1.4±0.4)% where the first uncertainty is statistical and the second is systematic. In addition, we estimate an upper limit on the non-resonant branching ratio B(Ds+→η′π+π0)

X(3872) ,ψ(3686) ,Γee ,Charmonium spectroscopy ,BESIII ,Physics ,QC1-999 - Abstract
Using the data sets taken at center-of-mass energies above 4 GeV by the BESIII detector at the BEPCII storage ring, we search for the reaction e+e−→γISRX(3872)→γISRπ+π−J/ψ via the Initial State Radiation technique. The production of a resonance with quantum numbers JPC=1++ such as the X(3872) via single photon e+e− annihilation is forbidden, but is allowed by a next-to-leading order box diagram. We do not observe a significant signal of X(3872), and therefore give an upper limit for the electronic width times the branching fraction ΓeeX(3872)B(X(3872)→π+π−J/ψ)

Physics ,QC1-999 - Abstract
We report a measurement of the parameter yCP in D0–D¯0 oscillations performed by taking advantage of quantum coherence between pairs of D0D¯0 mesons produced in e+e− annihilations near threshold. In this work, doubly-tagged D0D¯0 events, where one D decays to a CP eigenstate and the other D decays in a semileptonic mode, are reconstructed using a data sample of 2.92 fb−1 collected with the BESIII detector at the center-of-mass energy of s=3.773 GeV. We obtain yCP=(−2.0±1.3±0.7)%, where the first uncertainty is statistical and the second is systematic. This result is compatible with the current world average. Keywords: BESIII, D0–D¯0 oscillation, yCP, Quantum correlation

The objectives of this study were to determine the effects of conjugated linoleic acid (CLA) or betaine on the growth performance, carcass characteristics and fatty acid composition in backfat and belly fat of pigs fed distillers dried grains with solubles (DDGS). Thirty-two (60±2 kg) crossbred barrows (Duroc×Landrace×Yorkshine) were assigned to one of four diets randomly: (1) the control diet containing no corn DDGS (control group); (2) the diet containing 30% corn DDGS (DDGS-fed group); (3) the diet containing 30% corn DDGS and 10 g/kg CLA (CLA-fed group); (4) the diet containing 30% corn DDGS and 1 g/kg BET (BET-fed group). The pigs fed DDGS showed that the percentages of C18:2, polyunsaturated fatty acid (PUFA) and iodine value (IV) increased, while C18:1, saturated fatty acid (SFA) and monounsaturated fatty acid (MUFA) decreased. Pigs fed the DDGS+CLA or DDGS+betaine diets showed the increased percentage of SFA, and the decreased percentage of C18:2, PUFA and IV. In conclusion, results confirmed that the diets containing 30% DDGS had no detrimental effects on growth performance, but increased the percentage of PUFA and IV and decreased the percentage of SFA and MUFA in the backfat and belly fat. However, supplementation with CLA or BET can part reverse these effects on carcass fat in finishing pigs.

In this letter, the mixed $L_1$ – $L_2$ norm regularization is adopted to constrain the full-wave inversion solution of the multiparametric electromagnetic inverse scattering by the 3-D anisotropic objects. The mixed $L_1$ – $L_2$ regularization term is added to the standard $L_2$ norm cost function in the framework of the Born iterative method. In each iteration, the mixed $L_1$ – $L_2$ norm term is transformed into $L_2$ norm term through a weight matrix and the whole cost function is minimized by the conjugate gradient method. Numerical results show that, compared with the traditional Tikhonov $L_2$ regularization, the mixed $L_1$ – $L_2$ regularization can achieve higher reconstruction accuracy without additional computational cost due to the structural similarity constraint among different model parameters.

A hybrid method is proposed to reconstruct the subsurface 3-D objects with electromagnetic fields. The frequency-domain reverse time migration (FRTM) is first used to determine the approximate locations and sizes of the objects. Then, based on these results, the full-wave inversion, the variational Born iteration method (VBIM) is used to reconstruct both the shapes and dielectric parameters of the objects. The Monte Carlo method (MCM) is adopted to further refine the reconstructed shapes. Numerical simulations show that the proposed hybrid method can be effectively used for the subsurface imaging and detection.

The conventional finite-difference time-domain (FDTD) method is efficient for microwave frequencies, but requires a large number of time steps for low frequencies. In this work, a hybrid Crank–Nicolson (CN) FDTD-SPICE method is applied to field-circuit analyses in low- frequency wideband problems. The unconditionally stable CN-FDTD method is used to give a rapid full wave solution by overcoming the Courant–Friedrichs–Lewy (CFL) condition that constrains the conventional FDTD method at low frequencies. The hybrid CN-FDTD-SPICE method can be used for simulating the interactions between modern electronic circuit systems and a 3-D structure supporting field radiation and interferences. It can greatly improve the computational efficiency over the conventional FDTD method at low frequencies because its time increment can be significantly larger. Three numerical examples are presented to verify the accuracy and efficiency of this hybrid method. Its CPU time is much shorter than that of the conventional FDTD-SPICE method. This CN-FDTD-SPICE method becomes increasingly advantageous when the radiation fields are required as the system integration continues to accelerate.

In this article, we present an efficient phaseless inverse source method (PISM) to reconstruct equivalent sources on a printed circuit board (PCB) using magnitude-only single-plane near-field scanning. The equivalent source distribution reconstructed by the conventional source reconstruction method requires accurate near-field magnitude and phase information, but phase measurement is difficult in many cases due to inaccuracy and complexity. In order to describe the inverse problem between phaseless fields and radiation sources, a nonlinear cost function based on surface integral equations is established. The cost function of the PISM is rapidly minimized by an iterative optimization and regularization technique for nonlinear ill-posed systems. The proposed method gives the characterization of PCBs both for diagnostic tasks of radiation sources and the near-field radiation behavior prediction when the phase information is missing. It also shows excellent robustness in tackling with various near-field data and noises. Both numerical examples and laboratory experiments are given to verify the effectiveness of the proposed method.

Wideband low-frequency designs of inductors and wireless power transfer (WPT) coils are challenging because of the low-frequency breakdown in traditional numerical methods. In this letter, we apply a recently developed mixed finite-element time-domain (mixed FETD) method to overcome such low-frequency breakdown difficulties in designing inductors and WPT coils and verify the feasibility of the mixed FETD method for such models at low frequencies. This letter provides a demonstration for the design of the low-frequency electrically small electromagnetic devices.

Lanthanum (La) has been used as agricultural inputs in order to enhance yield and improve crop quality. However, little is known about the effect of La on the photosynthesis and growth of Amorphophallus sinensis, a worldwide food source. The effects of La on the photosynthetic and chlorophyll fluorescence parameters, photosynthetic pigments, corm yield, and konjac glucomannan (KGM) of Amorphophallus sinensis were investigated via field experiments. The leaves were sprayed with different concentrations of LaCl3 (20, 80, 160, and 240 mg L-1). The results exhibited an increasing effect of LaCl3 on photosynthetic rate, stomatal conductance, intercellular CO2 concentration, chlorophyll fluorescence parameters, photosynthetic pigments, corm yield, and KGM, when concentration was between 20 and 240 mg L-1, and the most effective concentration was 160 mg L-1. Therefore, moderate LaCl3 concentration may increase yield of Amorphophallus sinensis by enhancing the photosynthetic efficiency, increasing the corm yield, and KGM contents.

A finite-difference time-domain (FDTD) method is developed to analyze electromagnetic scattering from 3-D fully anisotropic periodic structures impinged by obliquely incident plane waves. Starting from Maxwell’s curl equations, we employ material transformation matrices to link the update of the electric and magnetic fields in the FDTD method. The problem under consideration is Bloch–Floquet periodic in the horizontal directions but finite in the vertical direction. At the FDTD truncation boundaries in the horizontal directions, the Bloch–Floquet periodic boundary conditions (BPBCs) are applied, while the perfectly matched layer (PML) absorbing boundary condition is implemented for the vertical direction. We design three different anisotropic models in 3-D simulations to validate our method with a commercial software package COMSOL. These examples show the accuracy and efficiency of the FDTD method for analyzing the propagation characteristics, including reflectance, transmittance, absorptance, and complex reflection and transmission coefficients for the fully anisotropic periodic structures.

The effects of Ce and/or Mg on the microstructure and tensile properties of Al-Si-Mg-Fe alloys have been systematically investigated. Results showed that the separate addition of Mg or Ce could cause grain and eutectic Si refinement to some extent, whereas, the combined addition of Mg and Ce had a more appreciable grain refinement and excellent eutectic Si modification, modifying the eutectic Si morphology from plate-like to fibrous. The combined addition of Mg and Ce produced a large number of nanosized precipitates containing Ce and Mg within eutectic Si. These nanosized precipitates inhibited the Si growth and also the increase of constitutional undercooling were responsible for the excellent Si modification. Moreover, the combined addition of Mg and Ce significantly improved the strength and elongation due to grain refinement and eutectic Si modification. The ultimate tensile strength, yield strength and elongation reached 313 MPa, 227 MPa, 5.7%, respectively. Fractographic studies on alloys with a combined addition of Mg and Ce have revealed more dimples on tensile surface indicating a transition from brittle to ductile fracture than alloys with separate additions of Mg or Ce. These experimental findings provide a new feasible scheme for rare earth elements application in aluminum alloy casting production.

A three-dimensional high-order reverse-time migration (3-D HO-RTM) method is proposed to perform subsurface electromagnetic imaging with an ultra-wideband radar (UWBR) system consisting of a multi-input and multi-output antenna array. By using a UWBR system to collect temporal scattering signals, subsurface targets can be detected, and the image of targets can be obtained by imaging methods such as the back-propagation method, frequency-wavenumber migration technique, time-reversal mirror, and reverse-time migration method. The proposed HO-RTM method is based on the high-order finite-difference time-domain (HO-FDTD) method to significantly reduce the computational cost in the conventional RTM method. The measured data from an experimental lunar exploration system Chang'E-5 have been collected on a 7 m × 2.5 m × 2.5 m laboratory model with volcanic ash and validated by the 3-D HO-RTM method. Results show that all buried objects can be effectively identified by the HO-RTM, and its computer memory and CPU time are only 3.87% and 0.7128% of the conventional RTM method, respectively.

Nanoparticles with sizes ranging between objects and microparticles (e.g. atom) have attracted much attention. These particles with various specialized functions not only deepen our understanding of nature, but also serve as the basis for the development of new advanced technology. The successful application of nanoparticles depends upon both the synthesis and the surface modification of these particles. Surface modification can improve the inherent characteristics of the nanoparticles and serve to prepare nanocomposites inexistent in nature. Nanocomposites are made from two or more of the solid phase, at least in one dimensional nano-level size (1-100 nm). The solid phase can be amorphous, semi-crystalline, grain, or a combination. The solid phase can also be organic, inorganic, or a combination. According to the size of the solid phase, nanocomposites generally include the following three types: nanoparticles and nanoparticle compounds (0-0 composite), nanoparticles and conventional bulk composites (0-3 composite) and composite nano-films (0-2 composite). In addition, the nano-layered structure material is ascribed to nano-material, and the multi-layer nanocomposite composed of different materials is also known as nanocomposites. Composite materials own excellent performance, which can be widely used in aerospace, defense, transportation, sports and other fields. Nanocomposites are one of the most attractive part of the composite materials. Due to the fast development in recent years, nanocomposites are put in an important position by the developed countries in the development of new materials. The research on nanocomposites includes organic-inorganic composites, nano-polymer matrix composites and inorganic-inorganic composites. In this chapter, combined with our research experience, we mainly introduce the nano-polymer matrix composites to the readers. In order to claim the nano-polymer matrix composites exactly, synthesis and modification of nanoparticles and preparation, characterization and applications of nano-polymer matrix composites were mainly discussed.

Little information is available regarding the effect of supplementing 25-hydroxyvitamin D3 during the transition period combined with a postpartum oral calcium bolus on Ca homeostasis. The objectives of the current study were to evaluate the effects of 25-hydroxyvitamin D3 combined with postpartum oral calcium bolus on lactation performance, serum minerals and vitamin D3 metabolites, blood biochemistry, and antioxidant and immune function in multiparous dairy cows. To evaluate the effects of 25-hydroxyvitamin D3 combined with oral calcium, 48 multiparous Holstein cows were randomly assigned to one of four treatments: (1) supplementing 240 mg/day vitamin D3 without a postpartum oral Ca bolus (control), (2) supplementing 240 mg/day vitamin D3 with an oral Ca bolus containing 90 g of Ca immediately post-calving (Ca + VitD), (3) supplementing 6 g/day 25-hydroxyvitamin D3 without an oral Ca bolus (25D), and (4) supplementing 6 g/day 25-hydroxyvitamin D3 with an oral Ca bolus containing 90 g of Ca immediately post-calving (Ca + 25D). Lactation performance during the first 21 days was measured. Blood was collected at the initiation of calving and then 1, 2, 7, 14, and 21 days relative to the calving date. The yield of milk (0.05 <, p <, 0.10), energy-corrected milk (p <, 0.05), 3.5% fat-corrected milk (p <, 0.05), and milk protein (p <, 0.05) were significantly higher in 25-hydroxyvitamin D3-treated groups within 3 weeks of lactation than in vitamin D3-treated cows. The iCa (p <, 0.05) and tCa (p <, 0.05) were higher in both Ca and 25D + Ca cows than in the control and 25D groups within 48 h. The concentrations of serum tCa (p <, 0.05), tP (p <, 0.05), and 25-hydroxyvitamin D3 (p <, 0.05) in 25D and 25D + Ca cows were higher than those in control and Ca cows within 21 days postpartum. Feeding 25-hydroxyvitamin D3 also showed a lower concentration of malondialdehyde (p <, 0.05), interleukin 6 (p <, 0.05), and tumor necrosis factor-alpha (TNF-α) (p <, 0.05), as well as a higher concentration of alkaline phosphatase (p <, 0.05), total antioxidant capacity (p <, 0.05), and immunoglobulin G (p <, 0.05) than vitamin D3. Supplementing Ca bolus also showed lower concentrations of alanine transaminase (p <, 0.05) and TNF-α (p <, 0.05). In conclusion, supplementing 25-hydroxyvitamin D3 during the transition period combined with a postpartum oral calcium bolus improved lactation performance, Ca homeostasis, and antioxidant and immune function of medium-production dairy cows within 21 days postpartum.

We report a study of the $e^{+}e^{-} \to D^{+} D^{-} \pi^{+} \pi^{-}$ process using $e^{+}e^{-}$ collision data samples with an integrated luminosity of $2.5\,\rm{fb}^{-1}$ at center-of-mass energies from 4.36 to $4.60 \rm{GeV}$, collected with the BESIII detector at the BEPCII storage ring. The $D_{1}(2420)^+$ is observed in the $D^{+} \pi^{+} \pi^{-}$ mass spectrum. The mass and width of the $D_{1}(2420)^+$ are measured to be $(2427.2\pm 1.0_{\rm stat.}\pm 1.2_{\rm syst.}) \rm{MeV}/c^2$ and $(23.2\pm 2.3_{\rm stat.} \pm2.3_{\rm syst.}) \rm{MeV}$, respectively. The first errors are statistical and the second ones are systematic. In addition, the Born cross sections of the $e^{+}e^{-} \to D_{1}(2420)^+D^- + c.c. \to D^{+} D^{-} \pi^{+} \pi^{-}$ and $e^{+}e^{-} \to \psi(3770) \pi^{+} \pi^{-} \to D^{+} D^{-} \pi^{+} \pi^{-}$ processes are measured as a function of the center-of-mass energy., Comment: Updated version published in PLB

Using a data sample of 448.1 × 10 6 ψ ( 3686 ) events collected with the BESIII detector at the BEPCII collider, we report the first observation of the electromagnetic Dalitz decay ψ ( 3686 ) → η ′ e + e − , with significances of 7.0σ and 6.3σ when reconstructing the η ′ meson via its decay modes η ′ → γ π + π − and η ′ → π + π − η ( η → γ γ ), respectively. The weighted average branching fraction is determined to be B ( ψ ( 3686 ) → η ′ e + e − ) = ( 1.90 ± 0.25 ± 0.11 ) × 10 − 6 , where the first uncertainty is statistical and the second systematic.

The objective of this study was to evaluate the effect of supplementation of 25-hydroxyvitamin D3 (25(OH)VD3) instead of vitamin D3 on the quality and seminal plasma antioxidant indicators of fresh and cryopreserved semen, serum minerals, vitamin D3 status, hormone levels, blood biochemistry, antioxidant and immune function in different age of bulls. Thirty-two Holstein bulls (16 bulls aged 24–36 months and weighted 727 ± 99.0 kg; 16 bulls aged 12 months and weighted 332 ± 24.9 kg) randomly assigned to 1 of 4 treatments in a 2 × 2 factorial arrangement with 2 sources of vitamin D3 (vitamin D3 or 25(OH)VD3) fed at 300 IU/kg dry matter intake and two different age of bull (maturity or prepuberty) through a 60 day period. Bulls were tied in individual pens without access to sunlight. Bulls fed 25(OH)VD3 had greater semen concentration (P = 0.03), sperms motility (P = 0.02), viability (P

Air-steam gasification of wood residue was explored in a research scale fluidized bed. Catalytic activity of two different kinds of metal catalysts (Ni/CeO2/Al2O3) with various catalyst loadings (20, 30, and 40%) was also investigated at various residence time (20, 40, and 60 min) and gasification temperature (750, 825, and 900 °C). Non-catalytic experiments were also carried out to determine the optimum conditions for tar cracking and hydrogen/syngas production. Results were revealed that the high temperature (∼900 °C) and high catalyst loading (∼40%) are favorable for tar cracking and high-purity hydrogen production. It was also found that for a residence time of 60 min, the tar cracking at the presence of Ni/CeO2/Al2O3 is 196% more than that of the case without any catalyst, while at the presence of Ni/Al2O3 it drops to 162%. Finally, the experiments were showed that Ni/CeO2/Al2O3 is more suitable for biomass conversion and hydrogen production than Ni/Al2O3.

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.

A solution-casting method has been developed to fabricate polymer/carbon nanofiber (CNF) buckypaper composite/polymer sandwich structures. Such layered nanocomposites can take advantage of the buckypaper's mechanical reinforcement effect and to introduce multi-functionalities including dynamic damping, electrical/thermal conductance and electromechanical responses. By controlling the solution chemistry, the structure, morphology and thus the performances of the composite samples were effectively manipulated. Dimethyl sulfoxide (DMSO) as a solvent was found to greatly enhance the wettability of polyvinyl alcohol (PVA) to carbon nanofiber as compared to water, and it increased polymer penetration in the buckypaper. It was also observed that PVA formed a surface coating layer surrounding individual CNF which behaved differently from bulk polymer. This intermediate layer played a critical role in determining the static mechanical reinforcement effect of buckypaper and further affected the composite dynamic damping characteristics. Incorporating carbon nanofiber buckypaper not only strengthened the PVA static mechanical performance but also lowered the loss modulus and tan d. By introducing the controlled structure of such composite sandwiches, it is possible to tailor the multi-functionalities targeting specific applications.

[FeCoSiN/SiNx]18 multilayer thin films with different SiNx layer thickness (t) ranging from 0.75 to 4 nm were fabricated by reactive magnetron co-sputtering without applying an external induced magnetic field. The grain size, morphology, electrical properties, and static and dynamic magnetic properties of [FeCoSiN/SiNx]18 multilayer thin films were investigated systematically. The results indicated that SiNx layer thickness had a profound impact on the physical properties of the multilayer thin films. The in-plane uniaxial magnetic anisotropy field (from 114 ± 21 to 163 ± 14 Oe), ferromagnetic resonance frequency (from 4.09 to 4.64 GHz) and resistivity (from 188 to 333 μΩ cm) could be tailored effectively by adjusting the SiNx layer thickness from 0.75 to 4 nm. Moreover, when the SiNx layer thickness reached 2 nm, the continuous growth of FeCoSiN polycrystalline layers was to be interrupted completely and it would result in a minimum grain size of 4.9 ± 0.7 nm. The root mean square roughness of multilayer thin films also acquired a minimum value of 0.8 nm and the corresponding easy axis coercivity achieved a minimum value of 2.8 ± 0.1 Oe.

We have fabricated the uniform CoO-coated Co nanocluster-assembled films at various oxygen gas flow rates (fO) by using a plasma-gas-condensation method and studied their anomalous Hall effect (AHE). The longitudinal resistivity (ρxx) of all the films exhibits a minimum at a temperature of Tmin. With the increase of fO, Tmin shifts from 150 to 300 K and has no longer change when fO is up to 0.10 sccm. The saturated AHE resistivity ( ρ x y A ) presents a near linear increase as fO rises. The anomalous Hall coefficient (Rs) at fO=0.20 sccm is 4.9×10−9 Ω cm G−1 at 300 K, which is almost three orders of magnitude larger than bulk Co. Moreover, at fO=0 and 0.05 sccm, the scaling exponents γ=1.2 and 1.24 in ρ x y A ∝ ρ x x γ are obtained in the region of 325–375 K; At fO=0.10, 0.15 and 0.20 sccm, ρ x y A decreases with the increase of ρxx on a double-logarithmic scale, following a new scaling relation of log ( ρ x y A / ρ x x ) = a 0 + b 0 log ρ x x in two temperature ranges of 5–300 K and 325–375 K.

Congenital hepatic arteriovenous fistulae (CHAVF) are direct communications between the hepatic artery and portal vein or hepatic vein. Clinical symptoms of CHAVF depend mainly on the location, duration, and blood flow volume of the fistulae, which are manifested by portal hypertension, hepatic fibrosis, cardiac enlargement, and eventually heart failure. Here we report a female patient aged 54 who was first admitted to our hospital due to recurrent chest tightness and palpitations in March 2014. Metoprolol tartrate and diltiazem hydrochloride were prescribed to control the symptom since nothing unusual was found in coronary angiography and abdominal ultrasound. Until April 2015, the patient's syndrome relapsed and abdominal computed tomography angiography and digital subtraction angiography revealed diffuse arteriovenous fistulae between the branches of hepatic artery and vein. Subsequently, 3 attempts at hepatic arterial embolization were performed; however, her abdominal pain aggravated and her heart discomfort could not be relieved eventually. Therefore, orthotopic liver transplantation as the salvage treatment was performed using a hepatic graft from a 19-year-old cardiac-death donor performed on January 1, 2017. Upon operation, the enlarged right hepatic artery whose diameter was approximately 1.5 cm in this recipient. And we also demonstrated a novel manner that the graft's celiac artery patch was anastomosed to the recipient's proper hepatic artery and gastroduodenal artery patch, which could reduce the blood flow successfully. The patient recovered uneventfully and was discharged home on the postoperatively 15th day. Since her liver transplantation, she has not complained of cardiac discomfort and abdominal pain, and her heart size has returned to normal on echocardiography. The hepatic artery peak velocity reduced to normal and the heart shadow also recovered. Nevertheless, for complex and diffuse intrahepatic vascular fistulae after failed hepatic artery embolization, liver transplantation should be strongly considered as the definitive treatment of choice.

NiZn-ferrite thin films were deposited by radio frequency magnetron sputtering. The effects of sputtering pressure, substrate temperature, and annealing temperature on the structure and magnetic properties of the NiZn-ferrite thin films were investigated. The results revealed that the lower sputtering pressure was beneficial for the crystallization and grain growth of the NiZn-ferrite films, and the saturation magnetization and coercivity of the films monotonously decreased with increasing the sputtering pressure. Moreover, it was also suggested that a higher substrate temperature could improve the crystallinity and saturation magnetization of the thin films. Additionally, the saturation magnetization monotonously increased with increasing the annealing temperature, while the coercivity exhibited a minimum at an annealing temperature of about 600 °C. The change of saturation magnetization and coercivity as a function of sputtering pressure, substrate temperature and annealing temperature could be attributed to the varied crystallinity, grain size, cation distribution and the intrinsic stress of the films.

An experiment was conducted to investigate the effects of dietary electrolyte balance (dEB) on the performance, urine pH, plasma biochemistry parameters, milk composition and immunoglobulin of sows during late gestation and lactation. Forty-eight sows (Landrace × Large white, mean parity 4.1 ± 1.75) were randomly allocated to four dietary treatments, with twelve replicates per treatment and one sow per replicate according to body weight and parity number. The dietary treatments were with dEB values of −100, 0, 162 (control group), and 300 mEq/kg from day 90 of gestation to farrowing, transitioning to −100, 0, 198 (control group), and 300 mEq/kg dEB, respectively, throughout the subsequent 21 days of lactation. Dietary electrolyte balance values were obtained by manipulating dietary sodium (Na) and chloride (Cl) levels. Calcium (Ca) and phosphorus (P) concentrations were held constant across experimental diets. Blood and urine samples were collected on day 107 of gestation, day of farrowing and weaning (day 21 of lactation). The colostrum and milk samples were obtained on day 0 and day 14 of lactation, respectively. The results showed that average daily feed intake (ADFI) of lactating sows was lower in sows fed a –100 mEq/kg diet compared with the other three groups (P 0.05) among dietary treatments. Urine pH values were lower (P 0.05). The percentages of protein, lactose and fat in the colostrum and milk were similar among dietary treatments (P>0.05). The immunoglobulin in plasma, colostrum and milk was higher in sows fed −100 or 0 mEq/kg diet compared with the control group (P

[FeCoSiN/SiNx]n multilayer thin films with different number of layers were fabricated by alternating magnetron sputtering at room temperature with no external magnetic field applied on substrates. A well-defined laminated structure consisting of 7 nm FeCoSiN magnetic layer and 2 nm SiNx insulating layer was observed by transmission electron microscopy (TEM). The static magnetic hysteresis loops of the [FeCoSiN/SiNx]n multilayer thin films measured by vibrating sample magnetometer (VSM) presented an obvious in-plane uniaxial magnetic anisotropy. The dynamic magnetic performance of the [FeCoSiN/SiNx]n multilayer films was studied by vector network analyzer and LLG equation. The results indicated that the total film thickness has slightly impact on the high-frequency magnetic performance of the multilayer thin films. When the total thickness of the [FeCoSiN/SiNx]n multilayer thin films increased to micron level, they could still maintain encouraging high-frequency magnetic properties and electrical property: the ferromagnetic resonance frequency fr=3.74 GHz, real permeability µ′=93.73, and electrical resistivity ρ=196 µΩ cm.

The objectives of this study were to determine the effects of conjugated linoleic acid (CLA) or betaine on the growth performance, carcass characteristics and fatty acid composition in backfat and belly fat of pigs fed distillers dried grains with solubles (DDGS). Thirty-two (60±2 kg) crossbred barrows (Duroc×Landrace×Yorkshine) were assigned to one of four diets randomly: (1) the control diet containing no corn DDGS (control group); (2) the diet containing 30% corn DDGS (DDGS-fed group); (3) the diet containing 30% corn DDGS and 10 g/kg CLA (CLA-fed group); (4) the diet containing 30% corn DDGS and 1 g/kg BET (BET-fed group). The pigs fed DDGS showed that the percentages of C18:2, polyunsaturated fatty acid (PUFA) and iodine value (IV) increased, while C18:1, saturated fatty acid (SFA) and monounsaturated fatty acid (MUFA) decreased. Pigs fed the DDGS+CLA or DDGS+betaine diets showed the increased percentage of SFA, and the decreased percentage of C18:2, PUFA and IV. In conclusion, results confirmed that the diets containing 30% DDGS had no detrimental effects on growth performance, but increased the percentage of PUFA and IV and decreased the percentage of SFA and MUFA in the backfat and belly fat. However, supplementation with CLA or BET can part reverse these effects on carcass fat in finishing pigs.
