A traffic flow model describing the formation and dynamics of jams was introduced by Berthelin et al. [“A for evolution jams,” Arch. Ration. Mech. Anal. 187, 185–220 (2008)], which consists a pressureless gas system under maximal constraint on density can be derived from Aw–Rascle condition ρ≤ρ* letting pressure vanish. In this paper, we give up consider following form: {ρt+(ρu)x=0,(ρu+εp(ρ))t+(ρu2+εup(ρ))x=0,in p(ρ)=−1ρ. The Riemann problem above is constructively solved. delta shock wave...
The purpose of this study was to evaluate the effect abdominal obesity and chronic inflammation on risk non-alcoholic fatty liver disease (NAFLD) among Chinese population. Overall, 50776 staff from Kailuan Group who participated in finished physical examinations between 2006 2007 were included cohort study. Their medical information collected they followed after examination. correlations waist-to-height ratio (WHtR) or serum high-sensitivity C-reactive protein (hs-crp) with NAFLD analyzed....
We constructively solve the piston problem for one-dimensional isentropic Euler equations a modified Chaplygin gas. give rigorous proof of global existence and uniqueness shock wave separating constant states ahead when advances into The results are quite different from those pure gas or generalized gas, in which Radon measure solution is constructed to deal with concentration mass on piston. When recedes we show strictly that only first-family rarefaction exists front will never occur. In...
The Riemann solutions for the relativistic Euler equations generalized Chaplygin gas are considered.It is rigorously proved that, as pressure vanishes, they tend to two kinds of solutionsto zero-pressure equations, which include a delta shock formed by weighted $\delta$-measure and vacuum state.

The formation delta shock waves and vacuum states is identified analyzed as vanishes. Unlike homogeneous case, are no longer self-similar. We rigorously justify that, vanishes, term converge zero pressure gas dynamics model body force. Moreover, also give some numerical results confirm theoretical analysis.
In this paper, we investigate the limiting behavior of Riemann solutions to Euler equations compressible fluid flow for modified Chaplygin gas with body force as two parameters tend zero.

Research has identified a link between the triglyceride-glucose index (TyG-i) and risk of mortality in severely ill patients. However, it remains uncertain if TyG-i affects by influencing heart rate (HR). This study enrolled 3,509 participants from Medical Information Mart for Intensive Care (MIMIC-IV) database who had triglyceride, glucose, HR data upon entering ICU. Cox regression models were applied to estimate effect on 28-day all-cause (ACM) in-hospital (IHM). Additionally, Kaplan-Meier...
Polyetheretherketone (PEEK) has been used extensively in biomedical engineering and it is highly desirable for PEEK implant to possess the ability promote cell growth significant osteogenic properties consequently stimulate bone regeneration. In this study, a manganese modified (PEEK-PDA-Mn) was fabricated via polydopamine chemical treatment. The results showed that successfully immobilized on surface, surface roughness hydrophilicity significantly improved after modification. Cell...
The Riemann problem for the relativistic generalized Chaplygin Euler equations is considered. Its two characteristic fields are genuinely nonlinear, but nonclassical solutions appear. formation of mechanism $\delta-$shock analyzed, that one-shock curve and two-shock do not intersect each other in phase plane. constructed, Rankine-Hugoniot conditions $\delta-$entropy condition clarified. Moreover, under entropy condition, we constructively obtain waves.
