A method for analyz ing the structu re of the white backgr ound in docu ment images is describ ed, along with applic ations to the proble m of isolati ng blocks of machine -printe d text. The appro ach is based on computa tionalgeometry algorith ms for off-li ne enumera tion of maximal white rectan gles and on-line rectan gle unific ation. These suppo rt a fast, simple, and gener al heuri stic ...

the adequacy of the swat model in the estimation of runoff, sediment yield and nitrate loss in the gorganrood watershed was tested, using the existing spatial database as the primary data. the model was then executed for a 31-years’ time period. in combination with the swat model, the sequential uncertainty fitting program (swat-cup and sufi-2) was added used to calibrate and validate a hydrolo...

background: bone marrow derived mesenchymal stem cells (mscs) are a population of multipotent progenitors which have the capacity of proliferation and differentiation into mesenchymal lineage cells. hypoxia could promote the proliferation of mscs. micro-rnas are endogenous rnas that can play an important role in some processes such as proliferation and differentiation. mir-210 could help for be...

in this paper,  we determine necessary and sufficient tauberian conditions under which convergence in pringsheim's sense of a double sequence of fuzzy numbers follows from its $(c,1,1)$ summability. these conditions are satisfied if the double sequence of fuzzy numbers is slowly oscillating in different senses. we also construct some interesting double sequences of fuzzy numbers.

raditionally, the function of a network has been to deliver packets from one endpoint to another. There was a distinct boundary between what is done within the network and what is done by the users. Processing within the network was limited basically to routing, congestion control and quality of service (QoS) schemes. This kind of a network can be regarded as “passive”. Several problems with “p...

introduction: obesity and visceral fat accumulation after menopause are associated with insulin resistance and cardiovascular diseases. we investigated the interactive effect of aerobic-resistance training and estrogen replacement therapy on visceral fat, omentin-1 and homa-ir in ovariectomized rats. materials and methods: fifty female wistar rats were ovariectomized (ovx) and divided into 5 gr...

introduction: 3-4, methylenedioxymethamphetamine (mdma) causes apoptosis in nervous system and several studies suggest that oxidative stress contributes to mdma-induced neurotoxicity. the aim of this study is to examine the effects of n-acetyl-l-cystein (nac) as an antioxidant on mdma-induced apoptosis. methods: 21 sprague dawley male rats (200-250mg) were treated with mdma (2×0,5mg/kg) or mdma...
