Open-domain question answering is a hot research topic in recent years. QA Track held by NIST has offered a new evaluation on this topic. However, its target is aimed at plain text collection only. This paper focuses on QA for heterogeneous data, including plain text, summaries, tabular data, and video programs. Discussion of what necessary adaptation could be done to deal with such kind of dat...

A 38-year-old man with pneumococcal meningitis, pneumocephalus, and CSF rhinorrhea was admitted to our hospital. The CSF rhinorrhea had no traumatic or iatrogenic etiology. The patient was treated with meropenem and recovered from meningitis. Axial plain CT showed pneumocephalus (figure 1, A and B), but no skull defects. Three-dimensional CT revealed defects of the posterior walls of the spheno...

The water distribution network is an important part of the plain environment improvement system. To make efficient use regional diversion source, scientifically distribute flow and improve carrying capacity Haishu Plain, river hydrodynamic model used in this paper to simulate intake location, reasonable quantity influence range transfer Plain. simulation results have high accuracy, which can pr...

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...
