Abstract:

Abstract The self-supplying vortex generator jet (SVGJ) is introduced to the separation control of a high-speed compressor cascade with an inlet Mach number of 0.67. A parametric investigation concerning the jet location and the injection angle is conducted numerically. The effect mechanisms of SVGJ on the cascade performance are analyzed in detail. The potentials of SVGJ at off-design points are also discussed. The vortex generated by the jet utilizing the pressure difference between the pressure surface and suction surface could enhance the fluid exchange between the boundary layer and the m

AbstractWe present numerical evidence of how three-dimensionalization occurs at small scale in rotating turbulence with Beltrami ($\mathit{ABC}$) forcing, creating helical flow. The Zeman scale ${\ell }_{\Omega } $ at which the inertial and eddy turn-over times are equal is more than one order of magnitude larger than the dissipation scale, with the relevant domains (large-scale inverse cascade of energy, dual regime in the direct cascade of energy $E$ and helicity $H$, and dissipation) each moderately resolved. These results stem from the analysis of a large direct numerical simulation on a g

Abstract:

Reperfusion of the ischemic myocardium is associated with a cytokine cascade that reflects a cellular response to injury. We studied this cascade in the mouse and found that acute surgical trauma in sham-operated animals obscured early changes in cytokine induction that occur during myocardial ischemia-reperfusion (MI/R). Therefore, we utilized a new implantable device that allows occlusion and reperfusion of the left anterior descending coronary artery in a closed-chest mouse at any time after instrumentation.

Chronic spontaneous urticaria (CSU) is characterized by daily recurring wheal and flare with itch for more than 6 weeks.

However, vascular endothelial cells are not likely to be simultaneously stimulated by m

Neuronal injury from ischemic stroke is aggravated by invading peripheral polymorphonuclear cells (PMNs). Neutrophils not only have a remarkable neurotoxic effect from the release of proteolytic enzymes, but also foster coagulation cascade by exposing membrane phosphatidylserine (PS), aggregating to platelets and releasing neutrophil extracellular traps (NETs). However, the role of circulating neutrophils in hypercoagulation state after AIS remains unclear. Our aim

CPF is the probability of particles formed at a certain depth h' reaching a certain depth h after i collisions. The work has considered the interaction of particles with matter; yielded the general solution for cascade probability method and a particular solution for the case of a collided particle not changing its direction and the flow rate not depending on time.

Abstract:

Palladium-catalysed competitive three-component C–H functionalisation reactions and cascade coupling ring-closing reactions of quinones with iodophenols in dihaloalkanes are described. During initial attempts to conduct C–H functionalisation reactions of quinones with iodophenols in dihaloalkanes, surprisingly a three-component C–H functionalisation reaction was discovered. Furthermore, as the reaction of chloroquinones with iodophenols was in progress, another surprising cascade coupling with ring closure was achieved. This provided an efficient single-step synthesis of naphtho[2,3- b]benzofu

Abstract:

ObjectiveCorrea’s cascade is a ‘Model for Gastric Cancer Development’ described by Peleyo Correa. The reversibility of Correa’s cascade remains debatable. The literature contains insufficient data on the specific stage of the cascade during which Helicobacter pylori is detected, treated, and the effect on prognosis. Herein, we aim to determine the prevalence of various precancerous and cancerous gastric lesions in patients presenting with dyspepsia, the prevalence of gastritis and H. pylori infection, the prevalence of duodenal pathology in patients presenting with dyspepsia, identify the stag

Abstract:

The One-Cycle Control(OCC) technique not only provides fast dynamic response, but also can admirably suppress the perturbation yielded by dc source and eliminate the undesired harmonic contents.The cascade H-bridge VSI has very low dv/dt and distortion in the voltage output waveform.Sample time staggered one-cycle control（STS-OCC） based on three-phase H-bridge cascade VSI is proposed. It yields all of the advantages of the OCC and cascade VSI.The results of the simulation and analysis show that the STS-OCC technology has high equivalent work frequency, little switching loss and quick dynamic r

Abstract:

Herein, we report an unprecedented Rh(III)-catalyzed C–H activation/annulation cascade of readily available enaminones with iodonium ylides towards the convenient synthesis of isocoumarins. This coupling system proceeds in useful chemical yields (up to 93%) via a cascade C–H activation, Rh-carbenoid migratory insertion and acid-promoted intramolecular annulation. The success of gram-scale reaction and diverse functionalization of isocoumarins demonstrated the synthetic utility of this protocol.

Our recent studies with cell mutants indicate that a cascade shared by the epidermal growth factor (EGF) and platelet-derived growth factor (PDGF) signals exists in NRK cells and mediates oncogenic signals induced by many oncogenes (A.

Abstract:

The amyloid cascade is central for the neurodegeneration disease pathology, including Alzheimer’s and Parkinson’s, and remains the focus of much current research. S100A9 protein drives the amyloid-neuroinflammatory cascade in these diseases. DOPA and cyclen-based compounds were used as amyloid modifiers and inhibitors previously, and DOPA is also used as a precursor of dopamine in Parkinson’s treatment. Here, by using fluorescence titration experiments we showed that five selected ligands: DOPA-D-H-DOPA, DOPA-H-H-DOPA, DOPA-D-H, DOPA-cyclen, and H-E-cyclen, bind to S100A9 with apparent Kd in t
