Common envelope evolution (CEE) is presently a poorly understood, yet critical, process in binary stellar evolution. Characterizing the full 3D dynamics of CEE difficult part because simulating so computationally demanding. Numerical studies have to conclusively determine how ejects and tight results, if only potential energy used propel envelope. Additional power sources might be necessary accretion onto inspiraling companion one such source. Accretion likely common post-asymptotic giant...
Purpose The purpose of this paper is to investigate the effect humble leadership on employee proactive behavior. authors propose that such mediated by psychological empowerment, and identification with leader moderates intervening role empowerment in leadership-employee behavior relationship. Design/methodology/approach Data were collected from 286 subordinate-supervisor dyads 4 industries Northern China. Hierarchical linear modeling analyses applied test research model. Findings Humble has...
A retrospective analysis of patients undergoing spinal deformity correction surgery by the assistance intraoperative computed tomography (iCT) with or without navigation system.To share our preliminary experience and iCT system applied to surgery.The has been shown improve accuracy safety in posterior instrumentation. It not only decreased operation time but also prevented excessive radiation exposure medical staff. To date, there are few reports about application surgery.From April 2009...
Signatures of 'evaporative' winds from exoplanets on short (hot) orbits around their host star have been observed in a number systems. In this paper, we present global adaptive mesh refinement simulations that track the launching winds, expansion through circumstellar environment, and interaction with stellar wind. We focus purely hydrodynamic flows including anisotropy wind explore orbital/fluid dynamics resulting detail. particular, find combination tidal Coriolis forces strongly distorts...
ABSTRACT The morphology of bipolar planetary nebulae (PNe) can be attributed to interactions between a fast wind from the central engine and dense toroidal-shaped ejecta left over common envelope (CE) evolution. Here we use 3D hydrodynamic adaptive mesh refinement (AMR) code AstroBEAR study possibility that PN outflows emerge collimated even an uncollimated spherical in aftermath CE event. output single simulation via smoothed particle hydrodynamics (SPH) phantom serves as initial...
Abstract The brain is known to express many long noncoding RNAs (lncRNAs); however, whether and how these lncRNAs function in modulating synaptic stability remains unclear. Here, we report a cerebellum highly expressed lncRNA, Synage , regulating via at least two mechanisms. One through the of as sponge for microRNA miR-325-3p, regulate expression cerebellar synapse organizer Cbln1 . other serve scaffold organizing assembly LRP1-HSP90AA1-PSD-95 complex PF-PC synapses. Although somewhat...
In the laser screen velocity measuring (LSVM) system, there is a deviation in consistency of optoelectronic response between start light and stop screen. When projectile passes through screen, projectile's over-target position, at which timing pulse LSVM system triggered, deviates from actual position (i.e., target deviation). Therefore, it brings errors to measurement velocity, has become bottleneck, affecting construction higher precision system. To solve this problem, paper proposes...
ABSTRACT We perform 3D hydrodynamical simulations to study recombination and ionization during the common envelope (CE) phase of binary evolution, develop techniques track ionic transitions in time space. simulate interaction a $2\, \mathrm{M_\odot }$ red giant branch primary $1\, companion modelled as particle. compare run employing tabulated equation state (EOS) that accounts for recombination, with an ideal gas EOS. During first half simulations, ∼15 per cent more mass is unbound EOS due...
We analyze a 3D hydrodynamic simulation of common envelope evolution to understand how energy is transferred between various forms and whether theory are mutually consistent given the setup. Virtually all unbinding in occurs before end rapid plunge-in phase, here defined coincide with first periastron passage. In contrast, total nearly constant during this time because positive gas from core particles counterbalanced by negative binding closer proximity inner layers plunged-in secondary....

To evaluate the outcome of computed tomography (CT)-guided percutaneous puncture and local chemotherapy for tuberculosis (TB) lumbar or lumbosacral spine.From January 2002 to August 2006, 49 patients with spinal TB in whom conservative treatment had failed were treated by minimally invasive surgery. There 21 female 28 male patients. The mean age was 47 ± 18 years (range from 12 78 years). 40 cases TB, 9 TB. From L(1) S(1), involved vertebral numbers 8, 26, 19, 10, respectively. In 3 a single...
We present a detailed hydrodynamic model that matches the structure of well-observed preplanetary nebula OH231.8+04.2. The purpose is to physically justified and coherent picture its evolutionary history from about 100 years start formation complex outer structures present. have adopted set initial conditions are heavily constrained by high-quality observations kinematics. shaping occurs while densities flows "light": less than surrounding AGB-wind environment. simulations show pairs...
This paper proposes that role stressor decreases helping behavior by undermining employees' normative commitment based on cognitive dissonance perspective and social exchange theory. We also propose two competitive assumptions of the moderating effect perceived organizational support. In this paper, we first examine these hypotheses in Study 1 then verify 2. 1, collected data from 350 employees Chinese enterprises. The results indicated had a negative link with via mediating commitment....
Abstract M2–9, or the “Minkowski’s Butterfly,” is one of most iconic outflow sources from an evolved star. In this paper we present a hydrodynamic model M2–9 in which nebula formed and shaped by steady, low-density (“light”), mildly collimated “spray” gas injected at 200 km s −1 that interacts with far denser, intrinsically simple pre-existing AGB wind has slowly all complex features within M2–9’s lobes (including knot pairs N3/S3 N4/S4 their respective leading edges, radial gradient Doppler...
This paper proposes a cost-effective, compact, noncontacting optoelectronic targeting system for measuring the distribution of projectile motion. The major elements this include light emitting diode (LED) array, photodiode detecting double-layered aperture arrays, adaptive threshold circuit, and date acquisition. Through cooperating with effectively reduces radiation width source to surface, filters out influence incident from adjacent apertures on both sides above each corresponding...
Electroencephalogram (EEG) is one of the most important neuroelectrical signals and often used to detect brain's dysfunction. However, analysis EEG signal extraction features from it has been a challenging task due complexity variability. It difficult recognize different stages real-time sleeping single automatically. In our study, were extracted rats using approximate entropy (ApEn) combined with bispectrum analysis. The results show that ApEn maximal amplitude can extract various in...
The influences and consequences of toroidal magnetic fields in shaping the visible lobes pre planetary nebulae ("prePNe") are explored this, last a series papers parameter studies prePN evolution. To probe these we start with steady, diverging, field-free wind model our previous add weak to moderate winds order generate arrays outcomes after 500 y, which structures grow almost homologously. As expected, stellar invariably form very thin dense axial features whose structure is best described...
We develop a physical framework for interpreting high-resolution images of pre planetary nebule ("prePNe") with pairs candle shaped lobes. use hydrodynamical models to infer the historical properties flows injected from nucleus that shape lobes into standard forms. First, we find suitable set parameters fast, collimated, tapered flow is actively reshaped by an exterior slow AGB wind and nicely fits basic shape, kinematics, mass, momenta this class prePNe. Next vary most influential...
