Microvascular perfusion is commonly used to study the peripheral cardiovascular system. Microvascular blood flow can be continuously and non-invasively monitored with laser speckle contrast imaging (LSCI) or with laser Doppler flowmetry (LDF). These two optical-based techniques give perfusion values in arbitrary units. Our goal is to better understand the perfusion time series given by each tec...

INTRODUCTION Microvascular changes in the skin due to pharmacological and physiological provocations can be used as a marker for vascular function. While laser Doppler flowmetry (LDF) has been used extensively for measurement of skin microvascular responses, Laser Speckle Contrast Imaging (LSCI) and Tissue Viability Imaging (TiVi) are novel imaging techniques. TiVi measures red blood cell conce...

Diffusional resistance in the porous particle is important in adsorption and reaction engineering. For a porous adsorbent particle subjected to an arbitrary change in the surrounding Ž . fluid-phase concentration, Glueckauf 1955 derived the linŽ . ear driving force LDF approximation that relates the average adsorbate concentration inside the particle directly with the concentration in the fluid...

AIM To evaluate the ability of structural parameters (as determined by retinal nerve fibre layer (RNFL) measurements obtained with the scanning laser polarimeter (SLP-NFA/GDx)) and functional parameters (as determined by automated perimetry) to discriminate between normal and glaucomatous eyes. METHODS In a case-control study, a total of 91 normal subjects and 94 patients with glaucoma underw...

Using fermionic techniques, we compute exactly the large deviation function (ldf) of the time-integrated injected power in several one-dimensional dissipative systems of classical spins. The dynamics are T = 0 Glauber dynamics supplemented by an injection mechanism, which is taken as a Poissonian flipping of one particular spin. We discuss the physical content of the results, specifically the i...

Optical network uses a tool for routing called Latin router. These routers use particular algorithms for routing. For example, we can refer to LDF algorithm that uses backtracking (one of CSP methods) for problem solving. In this paper, we proposed new approached for completion routing table (DRA&CRA algorithm) and compare with pervious proposed ways and showed numbers of backtracking, blocking...

A novel fusion approach for Language Identification called Languagedependent Fusion (LDF) is presented in this paper. A fusion system is a hybrid system which fuses the results from several individual sub-systems which utilize varied features, models, and/or classifiers. In LDF, instead of applying single fixed weighting coefficients to each sub-system, which happens in conventional approach su...

We present a simple model that can be used to account for the rheological behaviour observed in recent experiments on micellar gels. The model combines attachment–detachment kinetics with stretching due to shear, and shows well-defined jammed and flowing states. The large-deviation function (LDF) for the coarse-grained velocity becomes increasingly non-quadratic as the applied force F is increa...

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...
