rise in temperature occurred after soil temperature was measured in different time series. in this article, ldf (logarithmic derivative filter) innovative method is applied to detect anomalies. this method tests soil temperature time series for 12 earthquakes in iran with magnitudes of either five or greater than five. results from this method were collected. based on the results of ldf method ...

We compared the responses of finger blood flow to local and/or whole body warming, as measured by laser Doppler flowmetry (PERIFLUX PF-1d) (LDF), and by venous occlusion plethysmography (BF). The subject's hands were immersed in a bath of water whose temperature (Tw) was initially set at 25 degrees C. The tested hand was kept at about 10 cm above heart level to facilitate the drainage of finger...

OBJECTIVES Systemic sclerosis (SSc) is characterized by altered microvascular structure and function. Nailfold videocapillaroscopy (NVC) is the tool to evaluate capillary morphological structure and laser-Doppler Blood flowmetry (LDF) can be used to estimate cutaneous blood flow of microvessels. The aim of this study was to investigate possible relationships between capillary morphology and blo...

We investigated, using a direct, intravital microscopic technique, whether nitric oxide (NO) from neuronal nitric oxide synthase (nNOS) plays a role in the cerebral capillary flow response to acute hypoxia. Erythrocyte flow in subsurface capillaries of the frontoparietal cortex of adult Sprague-Dawley rats was visualized using epifluorescence videomicroscopy after fluorescent labeling of red bl...

PURPOSE To determine whether neural network techniques can improve differentiation between glaucomatous and nonglaucomatous eyes, using the optic disc topography parameters of the Heidelberg Retina Tomograph (HRT; Heidelberg Engineering, Heidelberg, Germany). METHODS With the HRT, one eye was imaged from each of 108 patients with glaucoma (defined as having repeatable visual field defects wit...

Cardiovascular parameters such as arterial blood pressure (ABP) and heart rate display pronounced circadian variation. The present study was performed to detect whether there is a circadian periodicity in the regulation of cerebral perfusion. Normotensive Sprague-Dawley rats (SDR, approximately 15 wk old) and hypertensive (mREN2)27 transgenic rats (TGR, approximately 12 wk old) were instrumente...

Digital replantation has recently become a common treatment method, and improvements in surgical techniques have increased its success rate.1 However, the overall failure rate remains a significant issue. Appropriatemeasurement of blood flow in transplanted tissue is important to prevent critical circulation failure. Of the various modalities advocated for postoperative monitoring of blood flow...

The heart activity is clearly evaluated in this study by analyzing spectral or frequency components of three Biosignals such as ECG, PPG and blood perfusion signal. This study is done with several healthy human subjects who are totally free from any type of cardiovascular diseases. ECG and PPG recordings were performed with electrode lead set and pulse transducer respectively connected to the s...

Pressure-induced vasodilation (PIV) is a mechanism whereby skin blood flow increases in response to progressive locally applied pressure. Skin blood flow in response to applied pressure decreased early in diabetic patients as a result of vascular and/or neural impairment. This study was designed to determine the effect of vascular changes on PIV in 1-week streptozotocin-induced diabetic mice. W...

The Linked Data Fragment (LDF) framework has been proposed as a uniform view to explore the trade-offs of consuming Linked Data when servers provide (possibly many) different interfaces to access their data. Every such interface has its own particular properties regarding performance, bandwidth needs, caching, etc. Several practical challenges arise. For example, before exposing a new type of L...
