Oscillatory-Flow PCR Microfluidic Chip Driven by Low Speed Biaxial Centrifugation [PDF]
Biosensors, 2023 PCR is indispensable in basic science and biotechnology for in-orbit life science research. However, manpower and resources are limited in space. To address the constraints of in-orbit PCR, we proposed an oscillatory-flow PCR technique based on biaxial ...

Friction and the oscillatory motion of granular flows [PDF]
Physical Review E, 2012 This contribution reports on numerical simulations of 2D granular flows on erodible beds. The broad aim is to investigate whether simple flows of model granular matter exhibits spontaneous oscillatory motion in generic flow conditions, and in this case ...

Entrainment of Lymphatic Contraction to Oscillatory Flow. [PDF]
Sci Rep, 2019 AbstractLymphedema, a disfiguring condition characterized by an asymmetrical swelling of the limbs, is suspected to be caused by dysfunctions in the lymphatic system. A possible source of lymphatic dysfunction is the reduced mechanosensitivity of lymphangions, the spontaneously contracting units of the lymphatic system.

Erythrocyte Aging, Protection via Vesiculation: An Analysis Methodology via Oscillatory Flow [PDF]
Frontiers in Physiology, 2018 We demonstrate that erythrocyte deformations, specifically of a type as occur in splenic flow (Zhu et al., 2017), and of the type that promote vesiculation can be caused by simple, yet tailored, oscillatory shear flow. We show that such oscillatory shear

Oscillatory Disturbed Flow Enhances Inflammatory and Oxidative Stress Markers in Endothelial Cells [PDF]
Methods and ProtocolsHemodynamics significantly impact the biology of endothelial cells (ECs) lining the blood vessels. ECs are exposed to various hemodynamic forces, particularly frictional shear stress from flowing blood.

Non‐invasive cardiac power measurements in decompensated heart failure in elderly adults: A prospective proof‐of‐concept study [PDF]
Physiological ReportsIn this proof‐of‐concept study, we evaluated the feasibility of non‐invasive estimation of cardiac power metrics—total power, steady power, oscillatory power, and oscillatory power fraction—and compared the prognostic and diagnostic value with ...

Numerical Study on the Non-Oscillatory Unstarted Flow in a Scramjet Inlet-Isolator Model
Aerospace, 2022 For successful scramjet engine operations, it is important to understand the mechanism of the inlet unstart phenomenon. Among various unstarted flow patterns in hypersonic inlets, the mechanism of low-amplitude oscillatory unstarted flow is still unclear.

Hovering in oscillatory flows [PDF]
Journal of Fluid Mechanics, 2016 We investigate the hovering dynamics of rigid bodies with up-down asymmetry placed in oscillating background flows. Recent experiments on inanimate pyramid-shaped objects in oscillating flows with zero mean component demonstrate that the resulting aerodynamic forces are sufficient to keep the object aloft.

The Half-Range Moment Method in Harmonically Oscillating Rarefied Gas Flows
Fluids, 2021 The formulation of the half-range moment method (HRMM), well defined in steady rarefied gas flows, is extended to linear oscillatory rarefied gas flows, driven by oscillating boundaries.
