One particular complexity of coronary artery is the natural tapering vessel with proximal segments having larger caliber and distal as get smaller. The a often leads to incomplete stent apposition (ISA). ISA alters hemodynamics creates pathological path develop complications such in-stent restenosis, more worryingly, thrombosis (ST). By employing state-of-the-art computer-aided design software, generic hoops were virtually deployed in an idealized tapered decreasing malapposition distance....
Patient-specific coronary endothelial shear stress (ESS) calculations using Newtonian and non-Newtonian rheological models were performed to assess whether the common assumption of blood behavior offers similar results a more realistic but computationally expensive model. 16 arteries (from patients) reconstructed from optical coherence tomographic (OCT) imaging. Pulsatile CFD simulations Quemada model performed. Endothelial other indices compared. Exploratory including local viscosity (LBV)...
"Controlled particle release and targeting" is a technique using score map (PRSM) transient (TPRSM) via backtracking to determine optimal drug injection locations for achieving an enhanced target efficiency (TE). This paper investigates the possibility of targeting desired through idealized but complex three-dimensional (3D) vascular tree geometry under realistic hemodynamic conditions by imposing Poiseuille velocity profile Womersley derived from cine phase contrast magnetic resonance...
Bubbles can inhibit underwater sound transmission, owing to density and acoustic-impedance mismatches associated reflection absorption of waves, also scattering due bubble-acoustic resonances. Thus, bubble curtains have been used reduce noise propagation. For the present study, a discrete model (DBM) utilising self-consistent coupled-oscillator theory was developed mitigation by curtains. The DBM is inherently able handle polydisperse-sized anisotropically-distributed bubbles. shown...
Initial shape of the release dictates spreading a gravity current over inclined non-erodible surfaces with small slope angles (\ensuremath{\theta} ⪅ 10\ifmmode^\circ\else\textdegree\fi{}) during short and long time evolution. For steeper slopes (\ensuremath{\theta}⪆ 10\ifmmode^\circ\else\textdegree\fi{}), initial volume dominates, taking on secondary one.
Background: The association between migraine and suicide ideation has been identified. However, the predictive factors of suicidal are still controversial whether with aura can serve as an independent associated factor is uncertain. This manuscript studied explored for ideation. Methods: We surveyed 9,057 medical students included 579 into our study population. All completed General Situation Questionnaire, Verified Headache Hamilton Anxiety Scale (24 items), Depression 36-item Health Survey...
This study aimed to investigate the impact of mechanical factors at baseline on patency a restorative conduit for coronary bypass grafts in an ovine model serial follow-up up 1 year.The analyses 4 [i.e. bending angle, superficial wall strain and minimum maximum endothelial shear stress (ESS)] were performed 3D graft models reconstructed (1-month) angiograms frame by core laboratory blinded late follow-up. The was documented Quantitative Flow Ratio (QFR®) that reflects physiological status...
Maintaining post-operative mechanical stability is crucial for successfully healing intertrochanteric fractures treated with the Proximal Femoral Nail Antirotation (PFNA) system. This primarily dependent on bone mineral density (BMD) and strain fracture. Current PFNA failure analyses often overlook uncertainties related to BMD body weight (BW). Therefore, this study aimed develop a probabilistic model using finite element modeling engineering reliability analysis assess performance of under...
Experiments were undertaken to develop a relationship between bubble size and acoustic-emission amplitude for vertical stream of water impacting pool. A particular focus is the formation discrete bubbles. Although diameter natural frequency sound emissions has been established through Minnaert's work, comprehensive investigation into missing. Air bubbles generated from impact falling-water streams varying diameters on an underlying pool their acoustic recorded using nearby hydrophone. Sound...
Coronary stent malapposition is a risk factor for complications like restenosis and thrombosis can be identified using intravascular optical coherence tomography (OCT). It has been suggested that blood flow disturbances (e.g. shear rate, viscosity, etc.) near struts may play role. However, the physical motion aggregation of activated platelets across malapposed remain unknown. Abnormal tissue surrounding seen in OCT imaging (Panel D) linked to platelet behaviour.
Large Eddy Simulations (LES) have been used to simulate the development, separation, reattachment and downstream recovery of flow over a smoothly contoured ramp. Five different subgrid models compared on grid intermediate resolution containing 19.2 million cells effect has examined by studying behavior one model four grids varying between 2.4 153.6 cells. All LES capture main features, but results fine generally show better agreement with experimental data.
This study presents the direct numerical simulations (DNS) of bubbly wake flows. The DNS with Lagrangian particle dynamics (LPD) model is applied to cases bubble dispersion over a cylinder and hydrofoil. validation performed on experimental data for behaviour in circular cylinder. It confirmed that simulated distributions stream agree well trend measurement. effect angle attack hydrofoil downstream distribution analysed. found deflection increases increasing attack. These results demonstrate...
The theory of " treating same syndrome with different methods" has been widely used in traditional Chinese medicine( TCM). It originated from Treatise on Febrile and Miscellaneous Diseases,and had objective formation factors. syndrome" TCM was a comprehensive manifestation etiology,characteristics,disease location trend disease. Considering the rich connotation syndrome",the diverse treatment methods,and complex ingredients prescriptions,different specific methods or prescriptions have often...
Although the relationship between bubble diameter and corresponding resonant frequency has been known since 1930s, link amplitude of sound physical properties is still unclear. Sound a parameter inevitably measured when passive acoustic measuring techniques are employed, its magnitude as related to not only size but also position in space relative measurement point. Here, we present study where individual bubbles were first generated through vertical plunging jet analyzed establish their...
