An unusual F3 basal stacking fault resulting from twin-dislocation interaction in magnesium is observed in molecular dynamics simulation. The F3 fault is produced in the twin lattice from the interaction between a migrating (101¯2) twin boundary and a partial dislocation of either a prismatic 〈c〉 edge, or a prismatic 〈c+a〉 mixed dislocation in the matrix. The condition is that the partial dislocation needs to have a negative sign and lie on a plane intersecting a compression site of the twin boundary. The F3 fault can also be generated when a positive basal 〈a〉 mixed dislocation in the twin lattice, with slip plane intersecting a compression site of the twin boundary, interacts with a basal-prismatic twinning disconnection. The F3 fault comprises two I1 faults that have the same character but are separated by two basal layers. It has one end connected to the twin boundary, and the other end bounded by a lattice defect with a Burgers vector identical to that of a 30° Shockley partial dislocation. The formation frequency of the F3 fault is higher at a lower shear stress (below ∼400 MPa) and/or a lower temperature (100 K and 200 K). The F3 fault can decompose into a glissile 30° Shockley and a T2 fault at a temperature above ∼400 K. The relationships between the F3 fault and other types of basal stacking faults such as I2, T2 or paired I1 faults that are separated by multiple basal layers are discussed.

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

Dark sector ,Dark photon ,Invisible decays ,Physics ,QC1-999 - Abstract
We report a search for a dark photon using 14.9 fb−1 of e+e− annihilation data taken at center-of-mass energies from 4.13 to 4.60 GeV with the BESIII detector operated at the BEPCII storage ring. The dark photon is assumed to be produced in the radiative annihilation process of e+e− and to predominantly decay into light dark matter particles, which escape from the detector undetected. The mass range from 1.5 to 2.9 GeV is scanned for the dark photon candidate, and no significant signal is observed. The mass dependent upper limits at the 90% confidence level on the coupling strength parameter ϵ for a dark photon coupling with an ordinary photon vary between 1.6×10−3 and 5.7×10−3.

SUMMARY: An experiment was conducted to determine the effect of feeding diets with Moringa flavonoiod meal (MFM) in laying ducks. A total of 225 one-day-old Sansui ducklings were randomly assigned to 3 dietary treatments with 5 replicates of 15 each. The growth performance of duckling, serum biochemical parameters and serum antioxidant index were determined. The egg production experiment was conducted using laying ducks from 23 to 27 wk of age. Both growth trail and egg production trail applied the following dietary treatments: (1) CON, basal diet; (2) basal diet + 0.2% MFM; (3) basal diet + 0.4% MFM. Dietary 0.2% MFM improved FCR and ADG in ducklings during 0 to 4 wk of age (P < 0.05). Laying ducks fed with MFM diets increased laying rate, average egg weight, and feed conversion rate (P < 0.05). For egg quality, dietary supplements with MFM improved eggshell strength while reduced proportion of soft shell eggs and yolk color (P < 0.05). For biochemical indices, no significant effects on total protein, albumin, IgG, and IgM were noted among all the treatments (P > 0.05).There were the tendencies to increase serum superoxide dismutases and glutathione peroxidase levels whereas decrease serum malondialdehyde concentration in ducklings. Taking together, dietary supplements with MFM improved growth performance of ducklings and egg production of laying ducks, enhanced eggshell strength whereas lightened yolk color. Moringa flavonoiod meal can be used as effective additives in laying duck production.

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

This study was conducted to determine the effect of Moringa oleifera stem (MOS) meal in ducks. A total of 225 ducklings at 1 D of age were randomly assigned to 3 dietary treatment groups with 3 replicates of 25 each. The growth experiment lasted 63 D . The egg experiment started from 23 to 27 wk of age. Ducks were randomly divided into 3 treatment groups with 3 replications of 15 each. The following dietary treatments were applied: 1) Control (CON), basal diet + 0% MOS meal; 2) basal diet + 2% MOS meal; 3) basal diet + 4% MOS meal. During 0 to 4 wk of age, ducks fed 2% MOS diet showed significantly increase in average daily feed intake (ADFI) and average daily gain (ADG; P 0.05). In egg production experiment, ADFI, average egg weight, laying rate, and FCR showed significant increase in 4% MOS diets (P 0.05). For serum biochemical parameters, total protein and albumin were increased in MOS diets during 0 to 4 wk of age, but decreased during 5 to 9 wk of age. For serum antioxidant index, superoxide dismutase and glutathione peroxidase values were increased whereas malondialdehyde values were decreased in MOS diets from 0 to 9 wk of age. The results suggest that MOS positively affects early growth performance and laying performane of duckling but partially affects egg quality. The antioxidative activity and immunological index may be improved.

Born cross section ,Effective form factor ,Threshold effect ,Physics ,QC1-999 - Abstract
Using e+e− collision data at ten center-of-mass energies between 2.644 and 3.080 GeV collected with the BESIII detector at BEPCII and corresponding to an integrated luminosity of about 500 pb−1, we measure the cross sections and effective form factors for the process e+e−→Ξ0Ξ¯0 utilizing a single-tag method. A fit to the cross section of e+e−→Ξ0Ξ¯0 with a pQCD-driven power function is performed, from which no significant resonance or threshold enhancement is observed. In addition, the ratio of cross sections for the processes e+e−→Ξ−Ξ¯+ and Ξ0Ξ¯0 is calculated using recent BESIII measurement and is found to be compatible with expectation from isospin symmetry.

ψ(3686) ,Inclusive branching fraction ,KS0 ,BESIII ,Physics ,QC1-999 - Abstract
Using 5.9 pb−1 of e+e− annihilation data collected at center-of-mass energies from 3.640 to 3.701 GeV with the BESIII detector at the BEPCII Collider, we measure the observed cross sections of e+e−→KS0X (where X=anything). From a fit to these observed cross sections with the sum of continuum and ψ(3686) and J/ψ Breit-Wigner functions and considering initial state radiation and the BEPCII beam energy spread, we obtain for the first time the product of ψ(3686) leptonic width and inclusive decay branching fraction Γψ(3686)eeB(ψ(3686)→KS0X)=(373.8±6.7±20.0) eV, and assuming Γψ(3686)ee is (2.33±0.04) keV from PDG value, we measure B(ψ(3686)→KS0X)=(16.04±0.29±0.90)%, where the first uncertainty is statistical and the second is systematic.

Proton ,Electromagnetic form factors ,Initial state radiation ,BESIII ,Physics ,QC1-999 - Abstract
The electromagnetic process e+e−→pp¯ is studied with the initial-state-radiation technique using 7.5 fb−1 of data collected by the BESIII experiment at seven energy points from 3.773 to 4.600 GeV. The Born cross section and the effective form factor of the proton are measured from the production threshold to 3.0 GeV/c2 using the pp¯ invariant-mass spectrum. The ratio of electric and magnetic form factors of the proton is determined from the analysis of the proton-helicity angular distribution.

Charmed baryon ,Λc+ decays ,Absolute branching fraction ,BESIII ,Physics ,QC1-999 - Abstract
Based on 586 pb−1 of e+e− annihilation data collected at a center-of-mass energy of s=4.6GeV with the BESIII detector at the BEPCII collider, the absolute branching fraction of Λc+→pKS0η decays is measured for the first time to be B(Λc+→pKS0η)=(0.414±0.084±0.028)%, where the first uncertainty is statistical and the second is systematic. The result is compatible with a previous CLEO result on the relative branching fraction B(Λc+→pKS0η)B(Λc+→pK−π+), and consistent with theoretical predictions of SU(3) flavor symmetry.

BESIII ,Σ hyperon ,Cross section ,Electromagnetic form factor ,Physics ,QC1-999 - Abstract
The Born cross sections of the e+e−→Σ+Σ¯− and e+e−→Σ−Σ¯+ processes are determined for center-of-mass energy from 2.3864 to 3.0200 GeV with the BESIII detector. The cross section lineshapes can be described properly by a pQCD function and the resulting ratio of effective form factors for the Σ+ and Σ− is consistent with 3. In addition, ratios of the Σ+ electric and magnetic form factors, |GE/GM|, are obtained at three center-of-mass energies through an analysis of the angular distributions. These measurements, which are studied for the first time in the off-resonance region, provide precision experimental input for understanding baryonic structure. The observed new features of the Σ± form factors require more theoretical discussions for the hyperons.

BESIII ,ϕ(2170) ,Excited ω states ,Excited ρ states ,Physics ,QC1-999 - Abstract
Born cross sections for the processes e+e−→ωη and e+e−→ωπ0 have been determined for center-of-mass energies between 2.00 and 3.08 GeV with the BESIII detector at the BEPCII collider. The results obtained in this work are consistent with previous measurements but with improved precision. Two resonant structures are observed. In the e+e−→ωη cross sections, a resonance with a mass of (2176±24±3)MeV/c2 and a width of (89±50±5)MeV is observed with a significance of 6.2σ. Its properties are consistent with the ϕ(2170). In the e+e−→ωπ0 cross sections, a resonance denoted Y(2040) is observed with a significance of more than 10σ. Its mass and width are determined to be (2034±13±9)MeV/c2 and (234±30±25)MeV, respectively, where the first uncertainties are statistical and the second ones are systematic.

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

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
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.

The objective of this study was to evaluate changes in ruminal microorganisms and fermentation parameters due to dietary supplementation of soybean and linseed oil alone or in combination. Four dietary treatments were tested in a Latin square designed experiment using four primiparous rumen-cannulated dairy cows. Treatments were control (C, 60 : 40 forage to concentrate) or C with 4% soybean oil (S), 4% linseed oil (L) or 2% soybean oil plus 2% linseed oil (SL) in a 4 × 4 Latin square with four periods of 21 days. Forage and concentrate mixtures were fed at 0800 and 2000 h daily. Ruminal fluid was collected every 2 h over a 12-h period on day 19 of each experimental period and pH was measured immediately. Samples were prepared for analyses of concentrations of volatile fatty acids (VFA) by GLC and ammonia. Counts of total and individual bacterial groups (cellulolytic, proteolytic, amylolytic bacteria and total viable bacteria) were performed using the roll-tube technique, and protozoa counts were measured via microscopy in ruminal fluid collected at 0, 4 and 8 h after the morning feeding. Content of ruminal digesta was obtained via the rumen cannula before the morning feeding and used immediately for DNA extraction and quantity of specific bacterial species was obtained using real- time PCR. Ruminal pH did not differ but total VFA (110 v. 105 mmol/l) were lower (P < 0.05) with oil supplementation compared with C. Concentration of ruminal NH3-N (4.4 v. 5.6 mmol/l) was greater (P < 0.05) due to oil compared with C. Compared with C, oil supplementation resulted in lower (P < 0.05) cellulolytic bacteria (3.25 × 108v. 4.66 × 108 colony-forming units (CFU)/ml) and protozoa (9.04 × 104v. 12.92 × 104 cell/ml) colony counts. Proteolytic bacteria (7.01 × 108v. 6.08 × 108 CFU/ml) counts, however, were greater in response to oil compared with C (P < 0.05). Among oil treatments, the amount of Butyrivibrio fibrisolvens, Fibrobacter succinogenes and Ruminococcus flavefaciens in ruminal fluid was substantially lower (P < 0.05) when L was included. Compared to C, the amount of Ruminococcus albus decreased by an average of 40% regardless of oil level or type. Overall, the results indicate that some ruminal microorganisms, except proteolytic bacteria, are highly susceptible to dietary unsaturated fatty acids supplementation, particularly when linolenic acid rich oils were fed. Dietary oil effects on ruminal fermentation parameters seemed associated with the profile of ruminal microorganisms.

ENGLISH ABSTRACT:Service integrators seek opportunities to align the way they manage resources in the service supply chain. Many business organisations can operate new, more flexible business processes that harness the value of a service approach from the customer’s perspective. As a relatively new concept, cloud computing and related technologies have rapidly gained momentum in the IT world. This article seeks to shed light on service supply chain issues associated with cloud computing by examining several interrelated questions: service supply chain architecture from a service perspective; the basic clouds of service supply chain; managerial insights into these clouds; and the commercial value of implementing cloud computing. In particular, to show how those services can be used, and involved in their utilisation processes, a hypothetical meta-modelling service of cloud computing is proposed. Moreover, the paper defines the managed cloud architecture for a service vendor or service integrator in the cloud computing infrastructure in the service supply chain: IT services, business services, business processes, which create atomic and composite software services that are used to perform business processes with business service choreographies.AFRIKAANSE OPSOMMING: Diensintegreeders is op soek na geleenthede om die bestuur van hulpbronne in die diensketting te belyn. Talle organisasies kan nuwe, meer buigsame besigheidprosesse, wat die waarde van ‘n diensaanslag uit die kliënt se oogpunt inspan, gebruik. As ‘n relatiewe nuwe konsep het wolkberekening en verwante tegnologie vinnig momentum gekry in die IT-wêreld. Die artikel poog om lig te werp op kwessies van die diensketting wat verband hou met wolkberekening deur verskeie verwante vrae te ondersoek: dienkettingargitektuur uit ‘n diensoogpunt; die basiese wolk van die diensketting; bestuursinsigte oor sodanige wolke; en die kommersiële waarde van die implementering van wolkberekening. ‘n Hipotetiese metamodelleringsdiens van wolkberekening word aanbeveel, veral om te toon hoe die dienste gebruik kan word. Die artikel definieer ook die bestuurde wolkargitektuur vir ‘n diensverskaffer of -integreerder in die wolkberekeningsinfrastruktuur van die diensketting: IT-dienste, besigheidsdienste, besigheidsprosesse, wat atoom- en saamgestelde programmatuurdienste voortbring, wat gebruik word om besigheidsprosesse met besigheidsdiensontwerpe uit te voer.
