The "Heavy legs" symptom is regarded as an early expression of chronic venous failure, estimated to affect 40% of the population in developing countries. A new methodology is proposed to approach the "tired or heavy legs" symptom. Seven females with this complaint applied a standard topical formulation during 28 days in one leg randomly chosen. Local blood flow records were obtained instantaneo...

Animal models are widely used to investigate the pathological mechanisms of spinal cord injury (SCI), most commonly in rats. It is well known that compromised blood flow caused by mechanical disruption of the vasculature can produce irreversible damage and cell death in hypoperfused tissue regions and spinal cord tissue is particularly susceptible to such damage. A fiberoptic photoplethysmograp...

Microcirculation is essential for the proper supply of oxygen and nutritive substances to the biological tissue and the removal of waste products of metabolism. The determination of blood flow in the capillaries is therefore of great interest to clinicians. A comparison has been carried out using the developed non-invasive, non-contact and whole field laser speckle contrast imaging (LSCI) based...

We present the statistical analysis of the Lateral Distribution Fuction (LDF) of air showers created by cosmic rays, for the AERAlet array of the Pierre Auger Observatory. To model the LDF of the AERAlet array, we propose the use of a normalised NKG-function, which has previously been applied to both the Regular and the Infill arrays of the observatory. By linearizing this model and iterating a...

magyar.ldf, the Hungarian Babel module, was rewritten in the autumn of 2003 to obey most of the Hungarian typographical rules. This article describes some implementation issues, TEX macro programming hacks, and LATEX typesetting trickery used in magyar.ldf. All features of the new magyar.ldf are enumerated, but only those having an interesting implementation are presented in detail. Most of the...

AIMS/HYPOTHESIS We used Laser Doppler Fluximetry (LDF) to define "normal" endothelial function in a large cohort of healthy children and adolescents and to evaluate skin microcirculation in paediatric patients with type 1 diabetes mellitus. METHODS LDF was performed in 102 healthy children (12.8 ± 3.3 years of age; 48 male) and 68 patients (12.9 ± 3.3 years of age; 33 male). Duration of disea...

A geometrically polar granular rod confined in 2D geometry, subjected to a sinusoidal vertical oscillation, undergoes noisy self-propulsion in a direction determined by its polarity. When surrounded by a medium of crystalline spherical beads, it displays substantial negative fluctuations in its velocity. We find that the large-deviation function (LDF) for the normalized velocity is strongly non...

In this paper, we consider the problem of scheduling real-time traffic in wireless networks under a conflict-graph interference model and single-hop traffic. The objective is to guarantee that at least certain fraction packets each link are delivered within their deadlines, which referred as delivery ratio. This has been studied before restrictive frame-based models, or greedy maximal schemes l...

This is a statisticalmodel (the “multiple logistic model”) for pooling data from many variables into a single probability estimate that a person examined in a health screening system requires medical care. Because discrete variables are frequently studied in health screening programs, the required assumption of multivariate normality of the predictor variables related to many statistical techni...

Flemingia macrophylla (Leguminosae), a native plant of Taiwan, is used as folk medicine. An in vitro study showed that a 75% ethanolic extract of F. macrophylla (FME) inhibited osteoclast differentiation of cultured rat bone marrow cells, and the active component, lespedezaflavanone A (LDF-A), was isolated. It was found that oral administration of FME for 13 weeks suppressed bone loss in ovarie...
