How different this seems from the desolate and malaria-ridden country widely portrayed by nineteenthand early twentieth-century visitors in the region, before the modern agricultural revolution changed the face of the landscape. At another time I hope to deal at length with the matter of cultivation in the Emathian plain in antiquity. At present, however, it may be useful to attempt to understa...

BACKGROUND Bony metastases were occasionally the initial presentations of malignancy. Overlooking of bony changes on radiographs in cancer patients with non-specific clinical symptoms may lead to delayed diagnosis. CASE PRESENTATION We presented a 70-year-old male having hypercalcemia and diffuse osteoblastic bone metastases on routine plain films. Finally, prostate cancer was diagnosed with ...

This paper describes very efficient attacks on plain RSA encryption as usually described in textbooks. These attacks exploit side channels caused by implementations that, during decryption, incorrectly make certain assumption on the size of message. We highlight different assumptions that are easily made when implementing plain RSA decryption and present corresponding attacks. These attacks mak...

the aim of this study is to assess the concentration of nitrate in groundwater resources of the kordkandi-duzduzan plain and to evaluate the vulnerability of the groundwater using avi and gods methods. kordkandi-duzduzan plain is located in east azarbaijan province in the northwest of iran, which groundwater is important for drinking and agriculture in the region due to scarcity of suitable sur...

in this paper, the artificial neural network (ann) approach is applied for forecasting groundwater level fluctuation in aghili plain,southwest iran. an optimal design is completed for the two hidden layers with four different algorithms: gradient descent withmomentum (gdm), levenberg marquardt (lm), resilient back propagation (rp), and scaled conjugate gradient (scg). rain,evaporation, relative...

background: although experiments on water quality are time consuming and expensive, models are often employed as supplement to simulate water quality. artificial neural network (ann) is an efficient tool in hydrologic studies, yet it cannot predetermine its results in the forms of maps and geo-referenced data. methods: in this study, ann was applied to simulate groundwater quality and geographi...
