Abstract: Abstract The upcoming Surface Water and Ocean Topography (SWOT) mission provides a promising opportunity for retrieval of high spatiotemporal resolution water surface height (WSH) over inland water bodies. To investigate the accuracy of SWOT derived WSH, the observations over Lake Baikal are simulated and a comprehensive evaluation is conducted in this study. Firstly, compared with Jason‐class altimeter WSH and in situ WSHs, the accuracy of SWOT KaRIn‐derived monthly WSHs and their spatiotemporal characteristics are analyzed. Secondly, a local cross‐calibration method is used to reduce the short wavelength roll error over lakes. The results show that, though SWOT has more observations than Jason‐class altimeter, the accuracy of the SWOT KaRIn‐derived monthly WSHs is difficult to be equivalent with those from Jason‐class altimeter, and varies with the number of duplicated observations, the spatial location and the time interval due to the effect of systematic erros and random errors, but can be significantly improved by local cross‐calibration method, especially at higher spatial resolutions after cross‐calibration associate with external nadir altimeter.

3. Abnormal Grain Growth Mechanism in the Twin-Roller Cast Al-Fe-Si Alloy in the Annealing Process

Author: Y. Z. Zhu, H. Peng, H. Huang, and J. C. Li
Subjects: Materials of engineering and construction. Mechanics of materials, TA401-492
Abstract: The twin-roller casting process is a novel technology used to produce aluminium and other alloys. In this study, the Al-Fe-Si alloy was twin-roller cast into a billet with a thickness of 7.0 mm. This was followed by an annealing process at 480°C for 16 hours. Abnormal grains of more than 15 mm in the nominal diameter were found to have formed on the surface of the billet. Scanning electronic microscopy observation, energy diffraction spectrum, microarea X-ray diffraction, and electronic backscattered diffraction analysis were performed to study this abnormal grain growth. The results showed that abnormal grain nucleates in the region of (100) texture formed in the twin-roller casting process. The growth of abnormal grain was governed by the coalescence of the abnormal grain with its surrounding normal grains, with an average orientation angle of 47° between both the types of grains. High-strain-concentrated regions on the surface layer of the billet were induced by the heterogeneously distributed Fe particles formed in the twin-roller casting process. The presence of these regions accelerates the abnormal grain growth in the following annealing process of the billet.

4. Distribution of inorganic phosphorus in profiles and particle fractions of Anthrosols across an established riparian buffer and adjacent cropped area at the Dian lake (China)

Author: G. S. Zhang and J. C. Li
Subjects: Geology, QE1-996.5, Stratigraphy, QE640-699
Abstract: Riparian buffers can trap sediment and nutrients sourced from upper cropland, minimizing the eutrophication risk of water quality. This study aimed to investigate the distributions of soil inorganic phosphorus (Pi) forms among profile and particle-size fractions in an established riparian buffer and adjacent cropped area at the Dian lake, southwestern China. The Ca-bound fraction (62 %) was the major proportion of the Pi in the riparian soils. After 3 years' restoration, buffer rehabilitation from cropped area had a limited impact on total phosphorus (TP) concentrations, but has contributed to a change in Pi forms. In the 0–20 cm soil layer, levels of the Olsen-P, non-occluded, Ca-bound, and total Pi were lower in the buffer than the cropped area; however, the Pi distribution between the cropped area and the buffer did not differ significantly as depth increased. The clay fraction corresponded to 57 % of TP and seemed to be both a sink for highly recalcitrant Pi and a source for labile Pi. The lower concentration of Pi forms in the silt and sand particle fraction in the surface soil was observed in the buffer area, which indicated that the Pi distribution in coarse particle fraction had sensitively responded to land use changes.

5. Single-atom verification of the information-theoretical bound of irreversibility at the quantum level

Author: J. W. Zhang, K. Rehan, M. Li, J. C. Li, L. Chen, S.-L. Su, L.-L. Yan, F. Zhou, and M. Feng
Subjects: Physics, QC1-999
Abstract: The quantitative measure of disorder or randomness based on the entropy production characterizes thermodynamical irreversibility, which is relevant to the conventional second law of thermodynamics. Here we report, in a quantum mechanical fashion, the first theoretical prediction and experimental exploration of an information-theoretical bound on the entropy production. Our theoretical model consists of a simplest two-level dissipative system driven by a purely classical field, and under the Markovian dissipation, we find that such an information-theoretical bound, not fully validating quantum relaxation processes, strongly depends on the drive-to-decay ratio and the initial state. Furthermore, we carry out experimental verification of this information-theoretical bound by means of a single spin embedded in an ultracold trapped ^{40}Ca^{+} ion. Our finding, based on a two-level model, is fundamental to any quantum thermodynamical process and indicates much difference and complexity in quantum thermodynamics with respect to the conventionally classical counterpart.

8. Gyro-stellar inertial attitude estimation for satellite with high motion rate

Author: C.-L. Lin, J.-C. Li, C.-L. Chiu, Y.-W.A. Wu, and Y.-W. Jan
Subjects: Physics::Space Physics, Aerospace Engineering, Astrophysics::Earth and Planetary Astrophysics
Abstract: For a common micro-satellite, orbiting in a circular sun-synchronous orbit (SSO) at an altitude between 500 and 600km, the satellite attitude during off-nadir imaging and staring-imaging operations can be up to ±45 degree on roll and pitch angles. During these off-nadir pointing for both multi-trip operation and staring imaging operations, the spacecraft body is commonly subject to high-rate motion. This posts challenges for a spacecraft attitude determination subsystem called Gyro Stellar Inertial Attitude Estimate (GS IAE), which employs gyros and star sensors to maintain the required attitude knowledge, since star trackers will severely degrade attitude estimation accuracies when the spacecraft is subject to high-rate motion. This paper analyses the star motion-induced errors for a typical star tracker, models the star motion-induced errors to assess the performance impact on the attitude estimation accuracy, and investigates the adaptive extended Kalman filter design in the GS IAE while evaluating its effectiveness.

Author: G.J. Qiao, D. Luo, S.D. Song, J.Q. Dong, Y.J. Shi, J. C. Li, D. Du, and Y. K. Martin Peng
Abstract: Analysis of helicon wave heating and current drive capability in EXL-50spherical torus plasmas has been conducted. It is found that the drivencurrent increases with the launched parallel refractive index n|| and peaksaround n|| = 4.0 when the frequency of the helicon wave is between 300 MHzand 380 MHz. The helicon wave current drive efficiency shows a relativelystable upward trend with increasing plasma temperature. Moreover, thedriven current decreases as the plasma density increases. We also analyzedthe current drive with helicon waves of 150 MHz and 170 MHz and foundthat the driven current at a lower frequency was lower than that at a higherfrequency. A positive proportional relationship exists between the drivencurrent and n||. Besides, as n|| increases, the profile of the driven currentbecomes wider. Finally, the effect of the scrape-off layer (SOL) region on thehelicon wave current drive was also investigated.

Abstract: Quantum heat engines are expected to outperform the classical counterparts due to quantum coherences involved. Here we experimentally execute a single-ion quantum heat engine and demonstrate, for the first time, the dynamics and the enhanced performance of the heat engine originating from the Liouvillian exceptional points (LEPs). In addition to the topological effects related to LEPs, we focus on thermodynamic effects, which can be understood by the Landau-Zener-Stuckelberg process under decoherence. We witness a positive net work from the quantum heat engine if the heat engine cycle dynamically encircles an LEP. Further investigation reveals that, a larger net work is done when the system is operated closer to the LEP. We attribute the enhanced performance of the quantum heat engine to the LZS process, enabled by the eigenenergy landscape in the vicinity of the LEP, and the EP-induced topological transition. Therefore, our results open new possibilities to towards LEP-enabled control of quantum heat engines and of thermodynamic processes in open quantum systems., Comment: 7 pages, 3 figures, Supplementary materials can be found in the Download source

Abstract: Cell-cell communication is critical for bacterial survival in natural habitats, in which miscellaneous regulatory networks are encompassed. However, elucidating the interaction networks of a microbial community has been hindered by the population complexity. This study reveals that γ-butyrolactone (GBL) molecules from Streptomyces species, the major antibiotic producers, can directly bind to the acyl-homoserine lactone (AHL) receptor of Chromobacterium violaceum and influence violacein production controlled by the quorum sensing (QS) system. Subsequently, the widespread responses of more Gram-negative bacterial AHL receptors to Gram-positive Streptomyces signaling molecules are unveiled. Based on the cross-talk between GBL and AHL signaling systems, combinatorial regulatory circuits (CRC) are designed and proved to be workable in Escherichia coli (E. coli). It is significant that the QS systems of Gram-positive and Gram-negative bacteria can be bridged via native Streptomyces signaling molecules. These findings pave a new path for unlocking the comprehensive cell-cell communications in microbial communities and facilitate the exploitation of innovative regulatory elements for synthetic biology.

Abstract: Wheat refers to a critical grain crop in China, and ensuring the stable, high quality, high yielding production of wheat is of significance to China’s food security. Chitosan oligosaccharide (COS), i.e., amino-oligosaccharide, is a bio-pesticide readily absorbed by crop plants, capable of improving nutrient absorption and reproductive growth. This study aimed to determine the effects of COS on promoting wheat growth and its effect on the accumulation of malondialdehyde (MDA), as well as common antioxidant enzymes frequently related to plant tolerance. As indicated from the results, COS treatment (50–800 μg/mL) led to the significant (P < 0.05) increase in the height, root length, fresh and dry weight of all the tested wheat cultivars (Bainong 4199, Zhengyu 11 and Bainong 207). Moreover, the physiological analysis indicated that the activity of four antioxidant enzymes, i.e., catalase (CAT), superoxide dismutase (SOD), peroxidase (POD) and polyphenol oxidase (PPO) in leaves, achieved the similar improvements, and MDA accumulation was reduced significantly (P < 0.05). The above results confirmed that COS can significantly promote the growth of wheat, and under the condition of increased antioxidant enzyme activity, it can reduce lipid peroxidation and may also improve stress resistance. Thus, using COS in commercial wheat production may be noticeably conducive to sustaining future wheat yields and food security in China.

Abstract: Mercury (Hg) is a global atmospheric pollutant. In its oxidized form (HgII), it can readily deposit to ecosystems, where it may bioaccumulate and cause severe health effects. High HgII concentrations are reported in the free troposphere, but spatiotemporal data coverage is limited. Underestimation of HgII by commercially available measurement systems hinders quantification of Hg cycling and fate. During spring–summer 2021 and 2022, we measured elemental (Hg0) and oxidized Hg using a calibrated dual-channel system alongside trace gases, aerosol properties, and meteorology at the high-elevation Storm Peak Laboratory (SPL) above Steamboat Springs, Colorado. Oxidized Hg concentrations displayed diel and episodic behavior similar to previous work at SPL but were approximately 3 times higher in magnitude due to improved measurement accuracy. We identified 18 multi-day events of elevated HgII (mean enhancement of 36 pg m−3) that occurred in dry air (mean ± SD of relative humidity = 32 ± 16 %). Lagrangian particle dispersion model (HYSPLIT–STILT, Hybrid Single-Particle Lagrangian Integrated Trajectory–Stochastic Time-Inverted Lagrangian Transport) 10 d back trajectories showed that the majority of transport prior to events occurred in the low to middle free troposphere. Oxidized Hg was anticorrelated with Hg0 during events, with an average (± SD) slope of −0.39 ± 0.14. We posit that event HgII resulted from upwind oxidation followed by deposition or cloud uptake during transport. Meanwhile, sulfur dioxide measurements verified that three upwind coal-fired power plants did not influence ambient Hg at SPL. Principal component analysis showed HgII consistently inversely related to Hg0 and generally not associated with combustion tracers, confirming oxidation in the clean, dry free troposphere as its primary origin.

Abstract: The detection of low-energy deposition in the range of sub-eV through ionization using germanium (Ge) with a bandgap of $\sim$0.7 eV requires internal amplification of charge signal. This can be achieved through high electric field which accelerates charge carriers to generate more charge carriers. The minimum electric field required to generate internal charge amplification is derived for different temperatures. A point contact Ge detector provides extremely high electric field in proximity to the point contact. We show the development of a planar point contact detector and its performance. The field distribution is calculated for this planar point contact detector. We demonstrate the required electric field can be achieved with a point contact detector., Comment: 10 pages, 19 figures

Throughout April 2022, IO columns above Storm Peak Laboratory, Colorado (3,220 m.a.s.l.) ranged from 0.7 ± 0.5 to 3.6 ± 0.5 × 1012 (average: 1.9 × 1012 molec cm−2). IO was consistently elevated in air masses transported from over the Pacific Ocean. The observed IO columns were up to three times higher and the range was larger than predicted by a global model, which warrants further investigation into iodine sources, sinks, ozone loss, and particle formation. IO mixing ratios increased with altitude. At the observed levels, iodine may be competitive with bromine as an oxidant of elemental mercury at cold temperatures typical of the free troposphere. Iodine‐induced mercury oxidation is missing in atmospheric models, understudied, and helps explain model underestimation of oxidized mercury measurements.

Abstract: Neomycin, a multicomponent aminoglycoside antibiotic, is mainly utilized in livestock husbandry and feed additives in animals. The antimicrobial potency of the main product neomycin B is higher than that of its stereoisomer neomycin C. However, the content of neomycin C as an impurity in the high-producing strain is relatively high, and its isolation or removal from neomycin B is quite difficult, which influences the widespread application of neomycin. In this work, the essential genes responsible for neomycin biosynthesis were evaluated and overexpressed to reduce the content of neomycin C. Among them, neoG and neoH are two novel regulatory genes for neomycin biosynthesis, aphA is a resistance gene, neoN encoding a radical SAM-dependent epimerase is responsible for the conversion of neomycin C to B using SAM as the cofactor, and metK is a SAM synthetase coding gene. We demonstrated that the reconstitution and overexpression of a mini-gene-cluster (PkasO*-neoN-metK-PkasO*-neoGH-aphA) could effectively reduce the accumulation of neomycin C from 19.1 to 12.7% and simultaneously increase neomycin B by ∼13.1% in the engineered strain Sf/pKCZ04 compared with the wild-type strain (Sf). Real-time quantitative polymerase chain reaction analysis revealed the remarkable up-regulation of the neoE, neoH, neoN, and metK genes situated in the mini-gene-cluster. The findings will pave a new path for component optimization and the large-scale industrial production of significant commercial antibiotics.

Abstract: Dissipation is vital to any cyclic process in realistic systems. Recent research focus on nonequilibrium processes in stochastic systems has revealed a fundamental trade-off, called dissipation-time uncertainty relation, that entropy production rate associated with dissipation bounds the evolution pace of physical processes [Phys. Rev. Lett. 125, 120604 (2020)PRLTAO0031-900710.1103/PhysRevLett.125.120604]. Following the dissipative two-level model exemplified in the same Letter, we experimentally verify this fundamental trade-off in a single trapped ultracold ^{40}Ca^{+} ion using elaborately designed dissipative channels, along with a postprocessing method developed in the data analysis, to build the effective nonequilibrium stochastic evolutions for the energy transfer between two heat baths mediated by a qubit. Since the dissipation-time uncertainty relation imposes a constraint on the quantum speed regarding entropy flux, our observation provides the first experimental evidence confirming such a speed restriction from thermodynamics on quantum operations due to dissipation, which helps us further understand the role of thermodynamical characteristics played in quantum information processing.

Abstract: A quantum thermal machine is an open quantum system coupled to hot and cold thermal baths. Thus, its dynamics can be well understood using the concepts and tools from non-Hermitian quantum systems. A hallmark of non-Hermiticity is the existence of exceptional points where the eigenvalues of a non-Hermitian Hamiltonian or an Liouvillian superoperator and their associated eigenvectors coalesce. Here, we report the experimental realisation of a single-ion heat engine and demonstrate the effect of the Liouvillian exceptional points on the dynamics and the performance of a quantum heat engine. Our experiments have revealed that operating the engine in the exact- and broken-phases, separated by a Liouvillian exceptional point, respectively during the isochoric heating and cooling strokes of an Otto cycle produces more work and output power and achieves higher efficiency than executing the Otto cycle completely in the exact phase where the system has an oscillatory dynamics and higher coherence. This result opens interesting possibilities for the control of quantum heat engines and will be of interest to other research areas that are concerned with the role of coherence and exceptional points in quantum processes and in work extraction by thermal machines., Comment: 20 pages, 9 figures

Abstract: Abstract The full data set of the Daya Bay reactor neutrino experiment is used to probe the effect of the charged current non-standard interactions (CC-NSI) on neutrino oscillation experiments. Two different approaches are applied and constraints on the corresponding CC-NSI parameters are obtained with the neutrino flux taken from the Huber-Mueller model with a 5% uncertainty. For the quantum mechanics-based approach (QM-NSI), the constraints on the CC-NSI parameters ϵ eα and ϵ eα s $$ {\epsilon}_{e\alpha}^s $$ are extracted with and without the assumption that the effects of the new physics are the same in the production and detection processes, respectively. The approach based on the weak effective field theory (WEFT-NSI) deals with four types of CC-NSI represented by the parameters [ε X ] eα . For both approaches, the results for the CC-NSI parameters are shown for cases with various fixed values of the CC-NSI and the Dirac CP-violating phases, and when they are allowed to vary freely. We find that constraints on the QM-NSI parameters ϵ eα and ϵ eα s $$ {\epsilon}_{e\alpha}^s $$ from the Daya Bay experiment alone can reach the order O $$ \mathcal{O} $$ (0.01) for the former and O $$ \mathcal{O} $$ (0.1) for the latter, while for WEFT-NSI parameters [ε X ] eα , we obtain O $$ \mathcal{O} $$ (0.1) for both cases.

Abstract: Genetically modified (GM) sugarcane is being developed for use in commercial production in several countries. Regulatory approval is required before these cultivars can be released and grown. Part of the approval process is to understand and assess the potential for environmental harm that might result from introduction of a GM organism. A key piece of biological information to assist in this analysis is to determine if and over what distance transgenes could be transferred by pollen from the GM plants and passed onto the next generation of sugarcane seeds. This is not known for sugarcane. Consequently, a field experiment was designed and conducted in Australia to determine the level of pollination between sugarcane cultivars (Saccharum spp. hybrids), and the distance over which it occurs, by placing non-GM flowering plants of cultivar in the centre of a field of non-GM cultivar . Mature inflorescences of the pollen receptor () were collected in eight directions up to 200 m from the centre of the field. Parentage of the seeds from the mother plants germinating in controlled conditions was determined by molecular markers. At a distance of 1 m in all directions from the pollen source, relatively high levels of hybridisation were found, though this was highest (100%) in the upwind direction. The level of hybridisation decreased in the shape of an exponential decay curve but detectable levels of hybridisation still occurred at 200 m downwind from the pollen source. The high level of cross- pollination at close distance was confirmed in a second experiment. The potential for pollen to travel several hundred metres and effect pollination and the subsequent production of sugarcane seeds means that containment of a transgene by distance cannot be assumed for sugarcane. The potential for cross- pollination of sugarcane plants or of compatible, sympatric relatives will be dependent upon local conditions. The risk of harm as a result of pollen carrying a transgene subsequently pollinating and producing seed will have to be evaluated against the likelihood of germination and survival of the seed and the nature and effects of the transgene.

Abstract: Natural rubber (NR) and butyl rubber (IIR) blends were compatibilized by isobutylene-isoprene block copolymer (IIBC) which was specifically synthesized with a relatively high content of isoprene (14.5% mole fraction). Aiming at high damping elastomers, the IIR acts as the high damping phase dispersed in the natural rubber (NR) matrix in this blend. The morphology and microstructure was characterized by atomic force microscope (AFM) and transmission electron microscope (TEM). The results indicated that the IIBC as a compatibilizer could greatly increase the interfacial thickness. Damping property was studied by dynamic mechanical thermal analyzer (DMTA) and rubber processing analyzer (RPA). The results showed that the loss factor greatly increased with adding IIBC, and this may be due to the improved stress transfer promoting the IIR phase to deform and then dissipate energy. The tensile test demonstrated that the tensile strength and modulus increased when 4 parts per hundred rubber [phr] of IIBC was added. Finally, the NR and new NR/IIR isolation bearing samples were prepared and tested on a pressure shear testing machine that could simulate the actual situation during an earthquake.The results showed that hysteretic loss (for one cycle) of the new NR/IIR sample is 83% higher than that of the NR sample, rendering the compatibilized blends potential in isolation rubber bearings application.

Abstract: Using data collected with the BESIII detector operating at the Beijing Electron Positron Collider, we search for the process $e^+e^-\rightarrow \eta_c\eta \pi^+\pi^-$. The search is performed using five large data sets recorded at center-of-mass energies of 4.23, 4.26, 4.36, 4.42, and 4.60 GeV. The $\eta_c$ meson is reconstructed in 16 exclusive decay modes. No signal is observed in the $\eta_c$ mass region at any center-of-mass energy. The upper limits on the reaction cross sections are determined to be 6.2, 10.8, 27.6, 22.6 and 23.7 pb at the 90% confidence level at the center-of-mass energies listed above.

Abstract: WOS: 000473026500002, Using a data sample of 4.48 x 10(8) psi(3686) events collected with the BESIII detector, we present a first observation of psi(3686) -> p (p) over bar phi, and we measure its branching fraction to be [6.06 +/- 0.38(stat)+/- 0.48(syst)] x 10(-6). In contrast to the earlier discovery of a threshold enhancement in the p (p) over bar -mass spectrum of the channel j/psi -> gamma p (p) over bar, denoted as X(p (p) over bar), we do not find a similar enhancement in psi(3686) -> p (p) over bar phi. An upper limit of 1.82 x 10(-7) at the 90% confidence level on the branching fraction of psi(3686) -> X(p (p) over bar)phi -> p (p) over bar phi is obtained., IHEP computing center; National Key Basic Research Program of China [2015CB856700]; National Natural Science Foundation of China (NSFC) [11335008, 11425524, 11625523, 11635010, 11735014, 11565006]; Chinese Academy of Sciences (CAS) Large-Scale Scientific Facility Program; CAS Center for Excellence in Particle Physics (CCEPP); Joint Large-Scale Scientific Facility Fund of the NSFC [U1332201, U1532257, U1532258, U1732263]; Joint Large-Scale Scientific Facility Fund of the CAS [U1332201, U1532257, U1532258, U1732263]; CAS Key Research Program of Frontier Sciences [QYZDJ-SSW-SLH003, QYZDJ-SSW-SLH040]; 100 Talents Program of CAS; INPAC and Shanghai Key Laboratory for Particle Physics and Cosmology; German Research Foundation DFG [CRC 1044]; Istituto Nazionale di Fisica Nucleare, Italy; Koninklijke Nederlandse Akademie vanWetenschappen (KNAW) [530-4CDP03]; Ministry of Development of Turkey [DPT2006K-120470]; National Science and Technology fund; Swedish Research Council; U.S. Department of Energy [DE-FG02-05ER41374, DE-SC-0010118, DE-SC-0012069]; University of Groningen (RuG); Helmholtzzentrum fuer Schwerionenforschung GmbH (GSI), Darmstadt, The BESIII Collaboration thanks the staff of BEPCII and the IHEP computing center for their strong support.

Abstract: The purpose of this study was to elucidate the regulatory effects of microRNA-655-3p (miR-655-3p) on growth and invasiveness of trophoblasts to influence the development of preeclampsia (PE).Relative levels of miR-655-3p and PBX3 in 24 PE pregnant women and 24 healthy ones were examined. Then, the regulatory effects of miR-655-3p and PBX3 on viability and invasiveness in HTR-8/SVneo cells were assessed by Cell Counting Kit-8 (CCK-8) and transwell assay, respectively. Next, the expression levels of apoptosis-associated genes were determined. Finally, the interaction between miR-655-3p and PBX3 was tested by Dual-Luciferase reporter assay.MiR-655-3p was upregulated in placental tissues of PE pregnant women than those of healthy ones. The overexpression of miR-655-3p suppressed viability and invasiveness, and induced apoptosis in HTR-8/SVneo cells. Besides, PBX3 was the target gene binding to miR-655-3p, and more importantly, the overexpression of PBX3 partially reversed the regulatory effects of miR-655-3p on viability and invasiveness in HTR-8/SVneo cells.MiR-655-3p is involved in the development of PE by regulating biological features of trophoblasts by targeting PBX3.

Abstract: We report the most precise measurements to date of the strong-phase parameters between D^{0} and D[over ¯]^{0} decays to K_{S,L}^{0}π^{+}π^{-} using a sample of 2.93 fb^{-1} of e^{+}e^{-} annihilation data collected at a center-of-mass energy of 3.773 GeV with the BESIII detector at the BEPCII collider. Our results provide the key inputs for a binned model-independent determination of the Cabibbo-Kobayashi-Maskawa angle γ/ϕ_{3} with B decays. Using our results, the decay model sensitivity to the γ/ϕ_{3} measurement is expected to be between 0.7° and 1.2°, approximately a factor of three smaller than that achievable with previous measurements, based on the studies of the simulated data. The improved precision of this work ensures that measurements of γ/ϕ_{3} will not be limited by knowledge of strong phases for the next decade. Furthermore, our results provide critical input for other flavor-physics investigations, including charm mixing, other measurements of CP violation, and the measurement of strong-phase parameters for other D-decay modes.

Abstract: Naringenin is a flavonoid compound with antioxidant effects. It is used to treat oxidative stress-related diseases, but its mechanism is unclear. In this experiment, we explored whether naringenin can increase the expression of superoxide dismutase 1(SOD1), reduce the oxidative stress of PC12 cells induced by homocysteine (Hcy), and decrease the apoptosis of PC12 cells induced by Hcy by inhibiting the expression of mir-224-3p. Different concentrations of Hcy (1, 3, 5, 8, and 10 mmol/L) was used to analyze effect of homocysteine on PC12 cells. A total of 5 mmol/L Hcy was used to induce the excitatory and neurotoxicity model of PC12 cells in vitro. The cells were divided into normal control, Hcy induction, Hcy + Naringenin (25 μM), Hcy + Naringenin (50 μM), Hcy + Naringenin (75 μM), Hcy + Naringenin (100 μM), and Hcy + Naringenin (150 μM) groups. The relative survival rate and activities of the PC12 cells were determined by the MTT method, and the apoptosis rate of the PC12 cells was determined by using flow cytometry. The Western blot method was used to determine the expressions of SOD1, Bax, Caspase-3, Caspase-8, and Bcl-2 in the PC12 cells induced by Hcy. The expressions of SOD1 mRNA and miR-224-3p in the Hcy-induced PC12 cells were determined by RT-PCR. Results found that Hcy increased the expression of miR-224-3p in a dose-dependent manner but decreased that of SOD1 mRNA and protein. Hcy also increased oxidative stress in the PC12 cells and the proapoptotic proteins Bax, Caspase-3, and Caspase-9. Furthermore, it decreased the expression of anti-apoptotic protein Bcl-2 and the activity and survival rate of the HT22 cells, but it increased the apoptosis of the PC12 cells. The treatment of Hcy-induced PC12 cells with different concentrations of naringenin for 24 h decreased the expression of miR-224-3p in a dose-dependent manner and increased the expressions of SOD1 mRNA and protein. The treatment also decreased the oxidative stress in the PC12 cells and the expressions of pro-apoptotic proteins Bax, Caspase-3, and Caspase-9; increased the expression of anti-apoptotic protein Bcl- 2; decreased the apoptosis of the PC12 cells; and increased the PC12 cells.The results suggest that Naringenin can decrease the apoptosis and oxidative stress of PC12 cells induced by Hcy and increase the activities and survival rates of PC12 cells. The mechanism may be related to naringenin decreasing the expression of miR-224-3p in PC12 cells induced by Hcy and increasing the expressions of SOD1 mRNA and protein.

Abstract: The decay ψ′→π+π−π0 is analyzed using a sample of 14 million ψ′ events taken with the BESII detector at the BEPC, and the branching fraction is measured to be B(ψ′→π+π−π0)=(18.1±1.8±1.9)×10−5. A partial wave analysis is carried out using the helicity amplitude method. ψ′→ρ(770)π is observed, and the branching fraction is measured to be B(ψ′→ρ(770)π)=(5.1±0.7±1.1)×10−5, where the first error is statistical and the second one is systematic. A high mass enhancement with mass around 2.15 GeV/c2 is also observed. Attributing this enhancement to the ρ(2150) resonance, the branching fraction is measured to be B(ψ′→ρ(2150)π→π+π−π0)=(19.4±2.5−3.4+11.5)×10−5. The results will help in the understanding of the longstanding “ρπ puzzle” between J/ψ and ψ′ hadronic decays.

Abstract: A partial-wave analysis is performed for the process e^{+}e^{-}→K^{+}K^{-}π^{0}π^{0} at the center-of-mass energies ranging from 2.000 to 2.644 GeV. The data samples of e^{+}e^{-} collisions, collected by the BESIII detector at the BEPCII collider with a total integrated luminosity of 300 pb^{-1}, are analyzed. The total Born cross sections for the process e^{+}e^{-}→K^{+}K^{-}π^{0}π^{0}, as well as the Born cross sections for the subprocesses e^{+}e^{-}→ϕπ^{0}π^{0}, K^{+}(1460)K^{-}, K_{1}^{+}(1400)K^{-}, K_{1}^{+}(1270)K^{-}, and K^{*+}(892)K^{*-}(892), are measured versus the center-of-mass energy. The corresponding results for e^{+}e^{-}→K^{+}K^{-}π^{0}π^{0} and ϕπ^{0}π^{0} are consistent with those of BABAR with better precision. By analyzing the cross sections for the four subprocesses, K^{+}(1460)K^{-}, K_{1}^{+}(1400)K^{-}, K_{1}^{+}(1270)K^{-}, and K^{*+}(892)K^{*-}(892), a structure with mass M=(2126.5±16.8±12.4) MeV/c^{2} and width Γ=(106.9±32.1±28.1) MeV is observed with an overall statistical significance of 6.3σ, although with very limited significance in the subprocesses e^{+}e^{-}→K_{1}^{+}(1270)K^{-} and K^{*+}(892)K^{*-}(892). The resonant parameters of the observed structure suggest it can be identified with the ϕ(2170), thus the results provide valuable input to the internal nature of the ϕ(2170).
