—In this paper, a fine frequency synchronization method with low complexity is proposed for Multi-Band Orthogonal Frequency Division Multiplexing (MB-OFDM) based Ultra-Wideband (UWB) systems. Low complexity is still one of the major difficulties in the design of fine frequency synchronizer for MB-OFDM UWB systems due to arctangent operations and Numerically Controlled Oscillator (NCO), both of...

The formation of healthy gametes depends on programmed DNA double-strand breaks (DSBs), which are each repaired as a crossover (CO) or non-crossover (NCO) from a homologous template. Although most of these DSBs are repaired without giving COs, little is known about the genetic requirements of NCO-specific recombination. We show that Fml1, the Fanconi anemia complementation group M (FANCM)-ortho...

This paper presents high-speed low-power small-area accumulator designs to be used in DDFS systems. To reduce the Numerically Controlled Oscillator (NCO) design complexity and size, only the most significant bits of the accumulator drive the phase to amplitude mapping block. Those bits need to be updated on every sampling clock, while the least significant bits of the accumulator are not visibl...

Abstract Herein we report the manipulation of perpendicular magnetic anisotropy (PMA), a very important technique for spintronics devices, which is achieved in an all-solid-state redox (reduction/oxidation) device. The device consisted NiCo 2 O 4 (NCO) thin film with c -axis orientation and proton-conducting polymer (Nafion). PMA NCO can be manipulated situ low voltage ( V ? 0.7 V) due to utili...

In high dynamic situations, the GPS carrier tracking loop requires a wide bandwidth to track a carrier signal because the Doppler frequency changes more rapidly with time. However, a wide bandwidth allows noises within the bandwidth of the tracking loop to pass through the loop filter. As these noises are used in the numerical controlled oscillator (NCO), the carrier tracking loop of a GPS rece...

Toluene diisocyanates (C6H3CH3 (NCO)2, TDIs) are synthetic low molecular-weight organic chemicals with two highly reactive isocyanate groups (-NCO). Exposure to TDI can cause irritation of the eyes, nose, and upper and lower respiratory tract, asthma-like responses, sensitive pneumonitis, and obstructive pulmonary function loss. In this paper, the exposure-effect relationships between long-term...

This paper explores the convergence of Machine-to-Machine (M2M) systems with Network-Centric Operations (NCO), and analyzes the perspective of integrating selforganizing gossip protocols as an information dissemination solution. An overview of the M2M communication paradigm and current standardization efforts regarding architecture are given. The paper includes an overview of the network-centri...

In a field trial conducted with eight varieties in the north coast area of Natal ratoon stunting disease (RSD) caused increasing lossesin yieldsof cane and sucrosefrom the plant to the second ratoon crop. All the varieties suffered losses in yield but the degree of loss differed markedly among the varieties. The total yield of sugar from the three crops was reduced by 38% in varieties NCo 376an...
