We present the program package NMSSMCALC for the calculation of the loop-corrected NMSSM Higgs boson masses and decay widths in the CP-conserving and CP-violating NMSSM. The full one-loop corrections ...to the Higgs boson masses are evaluated in a mixed renormalisation scheme of on-shell and DR¯ conditions. The Higgs decay widths include the dominant higher order QCD corrections, and the decays into bottom quarks, strange quarks and τ leptons are supplemented by higher order SUSY corrections through effective couplings. All relevant off-shell decays into two massive gauge bosons, gauge and Higgs boson and Higgs pair final states as well as into heavy quark pairs are computed. The input and output files feature the SUSY Les Houches Accord so that the program can easily be linked with existing computer tools.

Nature of problem:
Computation of the NMSSM Higgs mass spectrum including higher order corrections in a mixed renormalisation scheme of on-shell and DRbar conditions, and numerical calculation of the decay widths and branching ratios, both in the CP-conserving and in the CP-violating NMSSM. The decay widths include the dominant higher order QCD corrections and, for the neutral Higgs boson decays into a bottom quark pair, the higher order SUSY–QCD and the approximate SUSY–electroweak (elw) corrections up to one-loop accuracy. The decays into a strange quark pair include the dominant resummed SUSY–QCD corrections and the one into a τ pair the dominant resummed SUSY–elw corrections. Analogously for the charged Higgs boson the higher order SUSY corrections have been implemented for the decays into fermion pairs. In the real NMSSM, the decays into stop and sbottom pairs, respectively, contain the SUSY–QCD corrections. All relevant off-shell decays into massive gauge bosons, into gauge and Higgs bosons, into Higgs pairs and into heavy quark pairs have been taken into account. The input and output files feature the SUSY Les Houches Accord (SLHA).
Solution method:
The necessary input values are set in the two input files inp.dat (in the SLHA format) and bhdecay.in. The file inp.dat, where the choice between the real and the complex NMSSM can be made, is read in by CalcMasses.F, which calculates the one-loop corrected NMSSM Higgs mass spectrum. CalcMasses.F writes out all necessary parameters, masses and mixing angles in an SLHA format file slha.in, which is read in by bhdecay.f (by bhdecay c.f in the complex case). This Fortran routine then computes the decay widths and branching ratios and writes them out in an SLHA format file slha decay.out. Furthermore it writes out all parameters and mixing angles.
Restrictions:
At present the NMSSM Higgs spectrum is calculated at one-loop accuracy, the Higgs self-couplings at leading order, and no renormalisation group running of the input parameters is included. However, we are about to implement the two-loop corrections to the NMSSM Higgs boson masses and the Higgs self-couplings. Furthermore, the renormalisation group equations for the input parameters shall be provided in the near future. The program does not provide any distributions.

An aqueous-based, green, one-pot, and surfactant-less method to synthesize highly dispersed Pd nanoparticles (PdNPs) on graphene oxide (GO) nanosheets at room temperature was reported. The Pd/GO ...nanocomposites display an even distribution of highly-dispersed polyhedral PdNPs at high density onto GO sheets. The number density and size of deposited PdNPs are facilely adjusted by controlling the quantity of GO in the growth solution. The Pd/GO nanocomposites demonstrate a superior catalytic activity with apparent rate constant kapp of 1.057 min−1 and an excellent stability of up to 15 recycle times toward the reduction of 4-nitrophenol (4-NP) without any loss in efficiency. In addition, different factors including the amount of nanocatalysts, GO, ascorbic acid, and the molar ratio of 4-NP vs. NaBH4 also play crucial roles in manipulating the catalytic activities of the as-synthesized Pd/GO nanocomposites. This facile and green synthetic approach combined with their remarkable catalytic activity and durability highlight the potential of the Pd/GO nanocomposites in removal of recalcitrant organic compounds.
•The Pd/GO nanocomposites synthesized by a single step without any toxic chemicals and surfactants at room temperature.•Ascorbic acid was used as the mild reductant.•The PdNPs are highly-dispersed and of polyhedral shapes.•The Pd/GO showed superb catalytic activity (kapp = 1.057 min−1) and can be recycled up to 15 times without loss in efficiency.
This article describes the process of developing a model of a multi loop directional coupler for marine applications by replacing conventional segments with artificial transmission lines. As a ...result, a coupler with an area of 2455 mm2 (at a frequency of 0.9 GHz) was obtained, which is 75.15% less than when the coupler is implemented on quarter-wave segments. The relevance of this work lies in the development of compact devices with easily reproducible geometry through the use of artificial transmission lines.
ABSTRACT
We study the morpho-kinematics of the circumbinary envelope of Mira Ceti between ∼100 and ∼350 au from the stars using ALMA observations of the SiO (ν = 0, J= 5−4) and CO (ν = 0, J = 3−2) ...emissions with the aim of presenting an accurate and reliable picture of what cannot be ignored when modelling the dynamics at stake. A critical study of the uncertainties attached to imaging is presented. The line emissions are shown to be composed of a few separated fragments. They are described in detail and plausible interpretations of their genesis are discussed. Evidence for a focusing effect of the Mira A wind by Mira B over the past century is presented; it accounts for only a small fraction of the overall observed emission but its accumulation over several orbital periods may have produced an enhancement of CO emission in the orbital plane of Mira B. We identify a south-western outflow and give arguments for the anti-correlation observed between CO and SiO emissions being the result of a recent mass ejection accompanied by a shock wave. We discuss the failure of simple scenarios that have been proposed earlier to explain some of the observed features and comment on the apparent lack of continuity between the present observations and those obtained in the close environment of the stars. Evidence is obtained for the presence of large Doppler velocity components near the line of sight aiming to the star, possibly revealing the presence of important turbulence at ∼5–10 au away from Mira A.
ABSTRACT
We analyse new ALMA observations of the 29SiO (ν = 0, J = 8–7) and SO2 (ν = 0, 343,31−342,32) line emissions of the circumstellar envelope (CSE) of the oxygen-rich asymptotic giant branch ...(AGB) star, R Dor. With a spatial resolution of ∼2.3 au, the observations cover distances below ∼30 au from the star providing a link between earlier observations and clarifying some open issues. The main conclusions are the following. (i) Rotation is confined below ∼15 au from the star, with velocity reaching a maximum below 10 au and morphology showing no significant disc-like flattening. (ii) In the south-eastern quadrant, a large Doppler velocity gas stream is studied in more detail than previously possible and its possible association with an evaporating planetary companion is questioned. (iii) A crude evaluation of the respective contributions of rotation, expansion and turbulence to the morpho-kinematics is presented. Significant line broadening occurs below ∼12 au from the star and causes the presence of high Doppler velocity components near the line of sight pointing to the centre of the star. (iv) Strong absorption of the continuum emission of the stellar disc and its immediate dusty environment is observed to extend beyond the disc in the form of self-absorption. The presence of a cold SiO layer extending up to some 60 au from the star is shown to be the cause. (v) Line emissions from SO, 28SiO, CO and HCN molecules are used to probe the CSE up to some 100 au from the star, revealing the presence of two broad back-to-back outflows, the morphology of which is studied in finer detail than in earlier work.
Malnutrition is common in patients with COPD; however, little is known about its impacts on health-related quality of life (QoL) among patients with COPD. This study aimed to explore the nutritional ...status and dietary intake among outpatients with COPD in Vietnam and its possible associations with QoL.
A cross-sectional study was carried out in COPD outpatients visiting the COPD management unit at the National Lung Hospital, Hanoi, Vietnam between May 2017 and July 2017. Consecutive outpatients with a confirmed diagnosis of COPD were recruited with written inform consent. The nutritional status of participants was assessed using Subjective Global Assessment (SGA), and dietary intake via a 24-hour recall interview. The St George Respiratory Questionnaire (SGRQ) for COPD was used to investigate the participants' QoL. Sociodemographic and clinical data were extracted from hospital records.
Of 168 COPD outpatients involved in the study, three-quarters (74.4%) were diagnosed as malnourished (SGA B/C) and 81.5% reported unintentional weight loss. Most of the patients did not meet their estimated energy and protein requirements (85.7% and 89.9%, respectively). Malnutrition was significantly associated with disease severity (
=0.039) and ratio of protein intake to estimated requirement (
=0.005). QoL was low for all levels of malnutrition or disease severity, with well-nourished participants and those with less disease severity having better QoL (
=0.006 and
<0.001, respectively). With an extra meal per day, the odds of having malnutrition decreased 5.6 times (
<0.05) and the total SGRQ reduced 3.61 scores (
<0.05) indicating a better QoL.
Malnutrition and weight loss are prevalent among COPD outpatients. Most of the patients had inadequate dietary intake and low QoL. Nutrition counselling including increasing the number of meals per day with a focus on energy- and protein-rich foods may help improving nutritional status and QoL of patients with COPD in Vietnam.
Aim
To evaluate effect and costs of pertussis vaccination at Vietnam National Children's Hospital.
Methods
Pertussis cases were defined by positive laboratory tests of children under 5 years January ...2015‐June 2018, and data on patient characteristics, clinical data and hospitalisation costs were collected through patient records.
Results
Of 909 inpatients, 400 (44%) were <2 months, the age for first DPT vaccination, and mechanical ventilation was more common than in children >2 months (9% vs 4%, OR = 2.3, CI 1.3‐3.9), as well as persistent cough (99%), violent cough (87%) and pneumonia (91%). Comparing non‐vaccinated (172 cases, 19%) and DPT vaccinated patients >2 months of age hospitalisation was 106‐fold higher (149.6 vs 1.39 per 100 000 population), and proportion of severe patients, length of hospital stay and hospitalisation costs were significantly greater (23.9% vs 12.8%; 13 vs 10 days; 826 USD vs 582 USD, CI 23‐423, P = .03).
Conclusion
Incidence and proportion of complications among under 2‐month infants were higher than in older patients. DPT vaccination protects children from pertussis infection, and in case of pertussis infection decreases severity. Results indicate that the Ministry of Health should consider adding a booster vaccine for pregnant women in an extended vaccination programme.
ABSTRACT
The morpho-kinematics of the circumstellar envelope of oxygen-rich AGB star R Leonis is probed using Atacama Large Millimeter/submillimeter Array observations of the emission of molecular ...lines, including in particular CO(2–1) and 29SiO(5–4). Evidence is found for an episode of enhanced mass-loss, a few centuries ago, that produced a broad expanding shell of mean radius ∼6 arcsec and mean radial expansion velocity ∼5.5 km s−1. Detailed scrutiny of its structure, as displayed by the emission of the CO(2–1) line, reveals strong inhomogeneity and patchy morphology. Evidence is also found, in particular from the morpho-kinematics of the emission of SiO, SO, and SO2 lines probing the close neighbourhood of the star, for distinct gas outflows covering broad solid angles in the south-eastern, south-western, and north-western quadrants, suggesting significant contribution of the convective cell granulation in defining the pattern of mass ejection. A study of relative molecular abundances in these outflows suggests that a local thermal equilibrium description applies approximately beyond ∼10 stellar radii from the centre of the star but not at the smaller angular separations where the SO and SO2 molecules are found to be confined. Near the stellar disc, masers of the vibrationally excited SiO lines are found to probe north-western parts of a layer of hot gas, consistent with the earlier observation of an asymmetric expanding shell within 1–2 stellar radii from the centre of the star. Globally, a picture dominated by episodic and patchy mass ejections is found to prevail.
ABSTRACT
ALMA observations of CO(1–0) and CO(2–1) emissions of the circumstellar envelope of EP Aqr, an oxygen-rich asymptotic giant branch star, are reported. A thorough analysis of their properties ...is presented using an original method based on the separation of the data cube into a low-velocity component associated with an equatorial outflow and a faster component associated with a bipolar outflow. A number of important and new results are obtained concerning the distribution in space of the effective emissivity, the temperature, the density, and the flux of matter. A mass-loss rate of (1.6 ± 0.4)×10−7 solar masses per year is measured. The main parameters defining the morphology and kinematics of the envelope are evaluated and uncertainties inherent to de-projection are critically discussed. Detailed properties of the equatorial region of the envelope are presented including a measurement of the line width and a precise description of the observed inhomogeneity of both morphology and kinematics. In particular, in addition to the presence of a previously observed spiral enhancement of the morphology at very small Doppler velocities, a similarly significant but uncorrelated circular enhancement of the expansion velocity is revealed, both close to the limit of sensitivity. The results of the analysis place significant constraints on the parameters of models proposing descriptions of the mass-loss mechanism, but cannot choose among them with confidence.
