Gunn diodes use the Ridley–Watkins–Hilsum effect to generate low noise millimeter wave signals for communication and sensing applications. However, Monte Carlo calculations indicate that velocity–field characteristics of compensated GaAs contain a second peak due phonon scattering. A novel device leverages this double achieve ultra-wideband tunability low-noise waves is proposed in article. The...

Key place in this paper takes the study of political speech in the Republic of Croatia and their impact on voters, or which keywords are in political speeches and public appearances of politicians in Croatia that their voting body wants to hear. Given listed below we will define the research topic in the form of a question - is there a discrepancy in the perception of the public-political speec...

The paper describes the infrared (IR) thermal measurement facility at De Montfort University and the use of the facility to make IR temperature measurements on RF devices. Some of the limitations with conventional IR measurements will be described; including effects related to the low emissivity and optical transparency of materials. A novel method for improving the accuracy of IR temperature m...

Measuring the equilibrium electron density distribution and its response to perturbations provides important information to magnetically confined plasma research. A multichannel interferometer system is now routinely operating on the new quasihelically symmetric stellator ~HSX! to measure the equilibrium profile and electron density dynamics. The interferometer system has nine viewing chords wi...

For millimeter waves applications in the W-band 93.5-95.5 GHz, improved frequency synthesizers are highly demanded. Improved synthesizer should be tunable with high step resolution and possess phase noise performance, low spurious harmonic levels short locking time. These parameters conflicting developing a precision oscillator pure spectrum. Therefore, it's necessary to make compromisation bet...

Gunn rats lack UDP-glucuronosyltransferase (UDPGT) activity toward bilirubin. 4-Nitrophenol glucuronidation is mediated by several UDPGT isoforms that are distinct from bilirubin-UDPGT, one of which is induced after 3-methylcholanthrene (3-MC) administration in normal, but not in Gunn rats. In normal rats, 3-MC-inducible UDPGT mRNA concentration increased 15-fold in the liver and 3-fold in kidn...
