Abstract In this work, we experimentally demonstrate a high-performance laser-driven flyer (LDF) by introducing perfect absorber in the ablation layer to improve energy utilization efficiency, where is composed of silver nano-triangular array, dielectric layer, and film. The was realized simple low-cost colloid lithography technique, maximal absorbance can reach about 95% at 1064 nm under an op...

The COVRATIO statistic has been used to identify the presence of outlier in data, which is based on deletion approach, where determinant covariance matrix for full dataset excludes i-th row. This study proposes a novel discrimination method multivariate normal (MVN) distribution using idea statistic, denoted as . linear function (LDF) MVN will be compared statistic. Simulation results showed th...

Objective: it is well known that low omentin levels and reduced bioavailability of nitric oxide (NO) are outgrowth obesity. Besides, in obese subjects, microvascular dysfunction can be an initial stage cardiovascular diseases. This situation evaluated with skin laser–Doppler flowmetry (LDF).Methods: this study we investigated the effects 12 weeks moderate physical exercise on reactivity plasma ...

The laser Doppler flowmetry (LDF) technique provides the monitoring of microvascular blood flow perfusion. However, LDF monitors based on fiber-optic transducers have the serious drawback of generating TRAnsient Signal High-values (TRASH) in signals. These TRASH correspond to artifacts for clinicians as they prevent interpretations of the signal when they are numerous. Moreover, TRASH exclude t...

To date, the only published reports of bone mineral density (BMD) in MPS IV involve patients with MPS IVA; no reports exist describing BMD for MPS IVB. In this prospective study of BMD in three patients with MPS IVB, BMD was acquired by dual-energy X-ray absorptiometry (DXA) at whole body (WB), lumbar spine (LS), and lateral distal femur (LDF). Functional abilities, ambulatory status, medical h...

BACKGROUND Laser Doppler flowmetry (LDF) can be used to measure cerebral microcirculation in relation to stereotactic deep brain stimulation (DBS) implantations. OBJECTIVE To investigate the microcirculation and total light intensity (TLI) corresponding to tissue grayness in DBS target regions with high-resolution LDF recordings, and to define a resolution which enables detection of small ves...

The microcirculation, involving the smallest vessels in the body, is where the oxygen transport to all tissue occurs. Evaluating microcirculatory parameters is, therefore, important and involves the quantification of oxygen content of red blood cells (RBCs), the amount of RBCs and their speed. Diffuse reflectance spectroscopy (DRS) can be used to estimate blood oxygen saturation and fraction of...

Our research is related to the employment of photoplethysmography (PPG) and laser Doppler flowmetry (LDF) techniques (measuring the blood volume and flux, respectively) for the peripheral vascular system. We derive the governing equations of the wave dynamics for the case of extremely inhomogeneous parameters. We argue for the conjecture that the blood-vascular system as a wave-conducting mediu...
