BACKGROUND Annual influenza epidemics occur worldwide resulting in considerable morbidity and mortality. Spreading pattern of influenza is not well understood because it is often hampered by the quality of surveillance data that limits the reliability of analysis. In Japan, influenza is reported on a weekly basis from 5,000 hospitals and clinics nationwide under the scheme of the National Infec...

     Study of sedimentation trend in artificial recharge projects and flood spreading on the aquifer (Aquifer management) can be effective in designing structures and network management. Literature review shows that most studies in the flood spreading area shave been conducted in networks that have a low life span or low flood numbers. Since 1997, the flood spreading station on the Jajarm aquif...

The sequential emergence of specific T lymphocyte-mediated immune reactivity directed against multiple distinct myelin epitopes (epitope spreading) has been associated with clinical relapses in experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis (MS). Based on this association, an appealing and plausible model for immune-mediated progression of the advancing c...

Field-scale solute transport is typically difficult to model due to the complexity and heterogeneity of flow and transport in natural soils. The stream tube model attempts to stochastically describe transport across the field for relatively short travel distances by viewing the field as a series of independent vertical soil columns. This study investigates the stream tube model with the chemica...

[1] The Osbourn Trough is a fossil spreading center that rifted apart the Manihiki and Hikurangi Plateaus during Cretaceous time. Previous models of the Osbourn spreading center are based on data collected near the trough axis, and therefore only constrain the history of the Osbourn spreading center during the last few Ma of spreading. Our data set includes multibeam data collected northward to...

Flood spreading is among preventing method from damage of deluge, especially perishing of water and soil in latrine basins of arid and semiarid regions. Accumulation of sediments on the flood spreads regions lead to changes in soil fertility, revival and support of plant covering and controlling of desertification and change in physicochemical properties of soil in these regions. In order to me...

Optical fiber systems with periodically varying dispersion are the most perspective candidates for high capacity communication lines in the future. An opportunity to assemble the system from pieces of fiber with a dispersion of opposite sign gives an ample freedom to a designer. If systems are completely linear it is possible to design an ideal line, transmitting the pulses to an arbitrary long...

a significant problem in multicarrier communication systems is the necessity to reduce the value of papr (peak-to-average power ratio) of transmitting signal. in this thesis we study the effect of the system parameters such as coding and modulation types on papr and ultimate ber in a mc-cdma system. in this study we consider fading channel as well as the nonlinearity of transmitter’s amplifier ...

Abstract In order to study the surface interaction between binder and TKX-50, fluororubber F2603, ETPE, BR were adhered of TKX-50 by direct solvent volatilization method. The spreading coefficient adhesion work three adhesives analyzed a surficial performance test. coating effect safety coated binders discussed XPS, SEM, mechanical sensitivity. results showed that form efficient bonding. F2603 ...
