Wi-Fi technology has always been an attractive solution for catering the increasing data demand inmobile networks because of the availability ofWi-Fi networks, the high bit rates they provide, and the lower cost of ownership. However, the legacyWiFi technology lacks of seamless interworking betweenWi-Fi and mobile cellular networks on the one hand, and between Wi-Fi hotspots on the other hand. ...

The correction terms to the Sokolov-Ternov radiation formula due to variation of the magnetic field strength along the electron trajectory are calculated up to the second order in the power expansion of &r/B, where r is the formation time of radiation. It is found that the field-gradient effect reduces radiation intensity in the classical regime, and enhances it in the quantum regime. This is t...

We review the current status of resolved X-ray emission associated with extragalactic radio jets and hotspots. The primary question for any particular jet is to decide if the X-rays come from the synchrotron process or from inverse Compton scattering. There is considerable evidence supporting synchrotron emission for knots in the jets of FRI galaxies. For FRII terminal hotspots detected in the ...

Microwave-assisted selective liquefaction was proposed and used as a novel method for the isolation of holocellulose fibers. The results showed that the bamboo lignin component and extractives were almost completely removed by using a liquefaction process at 120 8C for 9 min, and the residual lignin and extractives in the solid residue were as low as 0.65% and 0.49%, respectively. Increasing th...

We present new XMM-Newton data of the high-redshift (z = 1.883), Mpc-sized giant radio galaxy 6C 0905+39. The larger collecting area and longer observation time for our new data means that we can better characterise the extended X-ray emission, in particular its spectrum, which arises from cosmic microwave background photons scattered into the X-ray band by the energetic electrons in the spent ...

6Li and 7Li two-time spin-alignment echo NMR correlation functions of single-crystalline LbN are recorded. Around room temperature, the decay of the spin-alignment echo amplitudes is induced by slow Li jumps perpendicular to the LbN layers. The hopping correlation functions can be best represented by a single exponential. The measured jump rates are consistent with those which were previously d...

Increased exposure to electromagnetic fi elds such as radio frequencies used by Wifi technology raise questions and concerns about their impact on health. For answer these questions, several scientifi c studies have carried out followed by results publication in prestigious scientifi c revues. Literature conducted on the effects of non-ionizing radiation and Wifi waves is vast and sometimes con...

We experimentally and numerically investigate the early-time hydrodynamic response of tin microdroplets driven by a ns-laser-induced plasma. Experimentally, we use stroboscopic microscopy to record laser-induced dynamics liquid droplets determine propulsion speed $(U)$ initial radial expansion rate $({\stackrel{\ifmmode \dot{}\else \.{}\fi{}}{R}}_{0})$. The ratio these two quantities is key par...
