Abstract In this study, PM 2.5 filter samples were collected from two high‐elevation sites located in the southern and northern areas of Tibetan Plateau (TP): Qomolangma Station for Atmospheric Environmental Observation Research (QOMS) Waliguan Baseline Observatory (WLG), respectively. Collected analyzed to examine regional differences aerosol properties relate them potential chemical processes TP area. The mass concentrations inferred measured components higher at WLG (11.2 μg m −3 )...

To observe the effect of heat-reinforcing needling on expression profile long non-coding RNA (LncRNA) in synovial tissue rabbits with cold-syndrome type rheumatoid arthritis (RA), so as to explore its mechanisms underlying improvement RA. A total 18 New Zealand were randomly divided into normal, model and (acupuncture) groups, 6 each group. The RA was established by injection mixed solution (emulsifier) ovalbumin powder(80 mg) + NaCl (20 mL) +Freund's complete adjuvant mL), combined cold...

Epicardial adipose tissue (EAT) contribute to atrial fibrillation (AF). We sought explore the role of FAI (fat attention index), volume, fat radiomic profile (FRP) from peri-coronary artery (PCAT) on coronary computed tomography angiography (CCTA) in determining presence AF and differentiating types. This study enrolled 300 patients underwent CCTA retrospectively divided them into (n = 137) non-AF groups 163). The imaging parameters FAI, volume FRP were excavated measured after PCAT...

The performance of an iodine radio ion thruster with a 4 cm diameter (IRIT4) was studied experimentally in this paper. Regulation the mass flow rates propellant is achieved by using temperature control method reservoir. Performance as propellants obtained at different total powers 40.6–128.8 W, grid voltages 1000–1800 V and rate 100 μg s−1. Results show that thrust specific impulse increase approximately linearly increasing power screen voltage. 2.32 mN 2361 s are nominal 95.8 W voltage 1800...

Abstract Two novel N‐embedded polycyclic units functionalized phosphorescent iridium(III) complexes ( Ir‐1 and Ir‐2 ) with substituents in different positions have been prepared. Complex bearing the substituent at 3‐position shows a distinct blue shift single‐peak emission (524 nm) higher luminescence efficiency (Φ PL =42 %) shorter lifetime (τ=282 ns) by comparison 4‐position substitution based complex =23 %, τ=562 ns), which exhibits dual‐peak (564 nm 602 nm), phosphorescence color can be...

A handy formula is presented to evaluate the effects of random surface errors on average power pattern for distorted reflector antennas. Based previous work Rahmat-Samii degradation errors, distortioninduced phase error expanded into a second-order Taylor series expansion in radiation integral. With probabilistic distribution closed-form expressions and variance boresight gain sidelobe levels are demonstrated by this formula. To show effectiveness formula, its applicability region derived....

To compare the efficacy differences between manual acupuncture (MA) and electroacupuncture (EA) in treatment of hemiplegia after acute ischemic stroke.Sixty-eight patients stroke were randomized into a MA group (34 cases) an EA cases). The routine western medication bilateral Dingnieqianxiexian (MS 6) adopted two groups. needles retained for 30 min. In group, even-needling technique was used 3 times during needle retaining, 1 min each time. on basis stimulation, therapy added, with...

A well-designed reflector surface with high beam pointing accuracy in electromagnetic performance is of practical significance to the space application cable mesh antennas. As for requirements, circular polarizations are widely used spaceborne antennas, which usually lead a shift offset reflectors and influence accuracy. two-step structural design procedure proposed overcome squint phenomenon circularly polarized reflectors. simple optimal an integrated optimization combined alleviate effect...

To compare the clinical efficacy differences between Tongdu Rezhen method and twirling-reinforcing needling for ankylosing spondylitis (AS) at early stage.Sixty-eight patients were randomly assigned to an observation group a control group, 34 cases in each one. The acupoint selection two groups was identical, taking Dazhui (GV 14) Mingmen 4) as main acupoints. Patients treated with method, while method. treatment given once day, seven treatments considered one course of treatment. TCM...

An innovative analytical method for the evaluation of directivity patterns cluster-fed reflector antennas with random feed element position and orientation displacements is presented. In this approach, sensitivities incident magnetic field, far electrical field are derived respect to displacements. The effect on pattern investigated via numerical characteristics pre-calculated sensitivities; meanwhile, upper lower bounds illustrated. A seven-element offset utilised as a example show...

To consider the effects of random surface errors on radiation pattern cylindrical reflector antennas, a second-order expansion computation method is proposed to calculate boresight gain loss and average power pattern. The additional phase error caused by distortion expanded into Taylor series in integral. Based probabilistic Gaussian distribution errors, can be simplified expression root-mean-square (rms) value errors. Simulation results Ku/Ka-bands parabolic illustrate that account for...

To explore heat-reinforcing needling for the metabolite profiling changes in serum of rheumatoid arthritis (RA) rabbits with liquid chromatograph-mass spectrometer (LC-MS) technique, and to investigate its mechanisms.Forty clean purple blue were randomized into a normal group, model reinforcing-reducing (RRN) twirling-reinforcing (TRN) (HRN) 8 cases each group. RA cold syndrome made ovalbumin freezing except those No treatment was given groups. The corresponding manipulations 7 days applied...

Micro laser propulsion used for some space tasks of micro‐satellites are preferred to providing small thrust and high specific impulse while keeping power consumption low. Most previous work on micro about transmission mode (T‐mode) using a CW laser. In this article, pulsed fiber is study the performance under reflection mode. Multi pulse (ranged from 100 2000) tests conducted double base propellant with vacuum less than 10 Pa. The frequency 20 kHz two kinds instantaneous density 4.77×106...
