OBJECTIVE To evaluate pathogenesis and clinical features of lower limb ulcers in systemic sclerosis (SSc) and to propose a classification that could be used in clinical practice. METHODS Charts of 60 patients with SSc who had lower limb cutaneous lesions were reviewed. All patients had videocapillaroscopy and arterial and venous lower limb color Doppler ultrasonography (US). Arteriography was...
Graph-based semi-supervised classification uses a graph to capture the relationship between samples and exploits label propagation techniques on the graph to predict the labels of unlabeled samples. However, it is difficult to construct a graph that faithfully describes the relationship between high-dimensional samples. Recently, low-rank representation has been introduced to construct a graph,...
Raynaud's phenomenon (RP) is a clinical sign of precocious abnormal microcirculation and can be considered a major risk factor for the development of connective tissue disease, especially systemic sclerosis (SSc). Nailfold videocapillaroscopy is the most valuable tool for the early diagnosis of SSc and related disorders. It allows classification of capillary abnormalities. Scoring capillaroscop...
Collecting information about (Suspended Sediment Concentration) SSC, in coastal Waters and estuaries is vital for proper management of coastal environments. Traditionally, SSC used to be measured by time consuming and costly point measurements. This Method allows you to accurately measure SSC only for a point in space and time. Remote sensing from air-borne and space-borne sensors have proved t...
[1] In this paper, by using a dynamic model with synoptic eddy and low-frequency flow (SELF) interaction, we show that the SELF feedback is of significant importance for the formation of the AO/NAO in both winter and summer. Although background storm activity is significantly weaker in summer than that in winter, the positive SELF feedback associated with the AO/NAO mode in summer can be as str...
The role of scale interactions in the maintenance of eddy kinetic energy (EKE) during the extreme phases of the intraseasonal oscillation (ISO) is examined through the construction of a new eddy energetics diagnostic tool that separates the effects of ISO and a low-frequency background state (LFBS; with periods longer than 90 days). The LFBS always contributes positively toward the EKE in the b...
Daily and seasonal fluctuations in mortality have been positively and significantly associated with ambient concentrations of atmospheric pollution and meteorological variables such as temperature and barometric pressure. However, much less is known about the health risk from atmospheric pollutants in the context of frequently occurring weather patterns. The objective of this study is to assess...
