Carrier transport in modern nanoelectronic devices involves physical scales which require quantum descriptions. Basic quantum mechanics describes systems determined by Hamiltonian state vectors |Ψ>, which provide the spatial and time dependences of the physical observables. A pure state density operator |Ψ><Ψ| as obtained by a single state vector contains the most complete information about the...

Cattle were infected with three isolates of Theileria parva and treated with halofuginone lactate during acute clinical disease. The health, weight gain and carrier state of the cattle were monitored for 15 months. Limited treatment rapidly reduced fever and parasitosis but parasite recrudescences occurred and 12 out of 21 treated cattle died. Persistent carrier states were identified with two ...

This paper discusses the low-frequency (LF) noise in submicron nMOSFETs under controlled transistor aging by hot-carrier stress. Both traditional, steady-state LF noise as well as the LF noise under periodic large-signal excitation were found to increase upon device degradation, for both hydrogen passivated and deuterium passivated Si–SiO2 interfaces. As hot-carrier degradation is slower in deu...

In this paper, differential modulation (DM) schemes, including single differential and double differential, are proposed for amplify-and-forward two-way relaying (TWR) networks with unknown channel state information (CSI) and carrier frequency offsets caused by wireless terminals in high-speed vehicles and trains. Most existing work in TWR assumes perfect channel knowledge at all nodes and no c...

COVID-19, a disease induced by SARS-CoV-2, became worldwide pandemic while SARS, closely related virus, SARS-CoV, was successfully contained. This is because unlike can be spread people who do not display any symptoms of disease, either they are in the early stages infection or their remains clinically silent. research article traces complex history diagnosis symptom-free (or asymptomatic) carr...

In this paper. we propose a baseband OFDM receiver for highspeed wireless local area network defined in IEEE 802.1 la physical layer. Algorithms for channel estimation/equalization. timing recovery, carrier frequency acquisition/tracking, and sampling clock tracking are individually designed and later integrated into a receiver architecture. Simulation results show that the proposed OFDM receiv...
