Methods From the Nordic JIA database 192 patients with available sera were included. Serum samples were collected at a median time of 4 months (IQR 2-7) after disease onset. Patients were followed prospectively for a median of 97 months (IQR 95-105). At the 8-year follow-up visit, data on remission according to the preliminary criteria of C. Wallace et al as well as joint damage according to JA...

This paper provides an extension of pathloss analysis in Urban, Rural and Semi-Urban environments in Oman. A new software package has been developed that incorporates modified propagation models and the proposition of radio frequency (RF) network design output for proper and efficient planning to be used by RF engineers for pathloss studies. The root-mean square error (RMSE) was calculated betw...

In this paper, we take initial steps toward developing energy-efficient broadcast algorithms for ad hoc wireless networks that operate under changing connectivity conditions. Such algorithms need to be distributed. And to be distributed these algorithms need to probe neighboring nodes to determine possible connectivities at different power levels. We proceed toward this goal by revisiting and m...

A cylindrical phantom, resembling average human neck, was prepared by using hydrogel sheets containing vinyl and polysaccharide. The phantom was used to obtain temperature distributions for 6 values of input power of radio frequency (RF) at 8MHz,by invasive thermometry technique, using thermistor probes. The inclusion of cervical vertebrae and calcium carbonate pieces (human bone representative...

Results of a propagation study on a free space optical link at 850 nm on a path 853 meters long and on a parallel 58 GHz radio link obtained over a 3-year period of observation are presented. The cumulative distributions of attenuation due to all of the hydrometeors combined as well as due to individual hydrometeors were obtained for both paths. The availability performances of the FSO link, th...

This paper introduces a new systematic approach to equivalent circuit model extraction for linear microwave passive circuits directly from full-wave frequency domain simulation. The devices being modeled may be either lossless or lossy. Adaptive frequency sampling is used to minimize the computational effort of EM simulation while critically assisting in determining the pole locations of an RF ...

A plasma diagnostic technique for measuring the electron density, electron temperature, and ion current near a surface in radio frequency ~rf! discharges is proposed. The sensor uses a small wire probe to determine the plasma potential and a small metal electrode to measure the current and voltage profiles. The values of current, sheath voltage, and time derivative of sheath voltage at three di...

Electron-beam EB evaporated MgO grows with 001 texture on amorphous CoFeB when the deposition rate is kept below 5 pm/s. Magnetic tunnel junctions MTJs fabricated using this method exhibit 240% magnetoresistance at room temperature for a 2.5 nm thick EB-MgO barrier, which is similar to the value for a radio frequency rf sputtered barrier with the same junction geometry. The average barrier heig...

In recent years, the delay in sowing has become a major obstacle to high wheat yield Jiangsu Province, one of producing areas China; hence, it is necessary screen varieties are resilient for late sowing. This study aimed provide an effective, fast, and non-destructive monitoring method soil plant analysis development (SPAD) values, which can represent leaf chlorophyll contents, late-sown winter...

Introduction and purpose: In high-field MRI phased transmit arrays are used to mitigate RF issues, e.g. optimizing the inhomogeneous B1 field using spatially tailored RF pulses played out by such an array. In order to design the RF pulses that produce the desired excitation field, the B1 field per coil must be mapped. Ideally, these B1 mapping techniques are fast and have a low SAR deposition. ...
