Aims. The main objective of this project is to characterise chromospheric activity FGK stars from the HARPS archive. We start, in first paper, by presenting a catalogue homogeneously determined emission (CE), stellar atmospheric parameters, and ages for 1674 sequence (MS), subgiant, giant stars. analysis CE level variability also performed. Methods. measured Ca II H&K lines using more than ...

⎯An analysis of a 3 dB lumped-element directional coupler (LEDC) based on arbitrary terminal impedance is described numerically. To solve the conflicted requirement for broad bandwidth and small size in LEDC, a new structure of coupler is introduced, which can significantly improve bandwidth and whose size is only 3 cm×4 cm on the conditions of the frequency domain of 410 MHz to 490 MHz. The me...

The principle for blood pressure measurement using pulse transit time is introduced in this paper. And the math model of synergetics theory is studied in detail .The synergetics theory is applied in the analysis of blood pressure measurement data. The simulation results show that the application of synergetics theory is helpful to judge the normal blood pressure, and the accuracy is up to 80%. ...

Formation of bonded dicarbon C-C centers is deduced from the observation of Raman lines at 1742, 1708, and 1674 cm21 in GaAs codoped with C and C after annealing at 850 ±C with concomitant loss of vibrational scattering from CAs. The frequencies agree with results of ab initio theory for a C-C split interstitial (deep donor) formed by the trapping of a mobile interstitial C (displaced CAs) atom...

conclusions we described a rare case of a usually aggressive thyroid angiosarcoma in a patient living in a non-alpine region, with an unusual favorable outcome after the operation and radiotherapy. case presentation an asymptomatic 61-year-old woman presented with a right lobe thyroid nodule with fine needle aspiration cytology indicating “suspicious for malignancy” was reported in our study. h...

This paper presents an image resolution enhancement algorithm using spatially invariant point spread function. Point spread function is used to constrain the solution space. This parameter is computed at each iteration step using partially restored image at each iteration, and High pass filter is used to impose the degree of edge smoothness on the solution. The resulting iterative algorithm exh...

A dose regimen of artesunate and amodiaquine based on arm span- or age range (DRAAAS), derived from a study of 1674 children, was compared with standard dose regimen of the same drugs calculated according to body weight (SDRAA) in 68 malarious children. Children on DRAAAS received 0.8-1.0 of artesunate/kg and 0.9-1.2 times amodiaquine/kg compared with those receiving SDRAA. Parasite and fever c...

Dispersion-managed solitons are reviewed within a Gaussian variational approximation and an integral evolution model. In the normal regime of the dispersion map (when the averaged path dispersion is negative), there are two solitons of different pulse duration and energy at a fixed propagation constant. We show that the short soliton with a larger energy is linearly (exponentially) unstable. Th...

This paper proposes CMOS LC-tank divide-by-3 injection locked frequency dividers (ILFDs) fabricated in 0.18 μm and 90nm CMOS process and describes the circuit design, operation principle and measurement results of the ILFDs. The ILFDs use two injection series-MOSFETs across the LC resonator and a differential injection signal is applied to the gates of injection MOSFETs. The direct-injection di...
