A single nucleotide polymorphism in the equine herpesvirus 1 (EHV-1) DNA polymerase gene (ORF30 A(2254) to G) has been associated with clinical signs of equine herpes myeloencephalopathy (EHM). The purpose of our study was to determine the odds ratio for this genetic marker and EHM using a panel of field isolates from North America collected over the past twenty-three years. EHV-1 isolates cult...

A parallel structure for a CMOS four-quadrant analog multiplier is proposed and analyzed. By applying differential input signals to a set of combiners, the multiplication function can be implemented. Based on the proposed structure, a low-voltage high-performance CMOS four-quadrant analog multiplier is designed and fabricated by 0.8m N-well doublepoly-double-metal CMOS technology. Experimental ...

The problems of energy harvesting in wireless communication systems have recently drawn much attention. In this paper, we focus on the investigation of energy harvesting maximization (EHM) in the important secrecy multi-input multioutput (MIMO) systems where little research has been done due to their complexity. Particularly, this paper studies the resource allocation strategies in MIMO wiretap...

Biotrophic pathogens, like the powdery mildew fungi, require living plant cells for their growth and reproduction. During infection, a specialized structure called the haustorium is formed by the fungus. The haustorium is surrounded by a plant cell-derived extrahaustorial membrane (EHM). Over the EHM, the fungus obtains nutrients from and secretes effector proteins into the plant cell. In the p...

The Arabidopsis thaliana resistance to powdery mildew8.2 (RPW8.2) protein is specifically targeted to the extrahaustorial membrane (EHM) encasing the haustorium, or fungal feeding structure, where RPW8.2 activates broad-spectrum resistance against powdery mildew pathogens. How RPW8.2 activates defenses at a precise subcellular locale is not known. Here, we report a comprehensive mutational anal...

Wideband direct-conversion harmonic-rejection (HR) receivers for softwaredefined radio aim to remove or relax the pre-mixer RF filters, which are inflexible, bulky and costly [1,2]. HR schemes derived from [3] are often used, but amplitude and phase mismatches limit HR to between 30 and 40dB [1,2]. A quick calculation shows that much more rejection is wanted: in order to bring harmonic response...

We describe a general offset-cancelling architecture for analog multiplication using chopper stabilization. Chopping is used to modulate the offset away the output signal where it can be easily filtered out, providing continuous offset reduction which is insensitive to drift. Both square wave chopping and chopping with orthogonal spreading codes are tested and shown to reduce the offset down to...

This paper reports on a fully-integrated CMOS switchable directconversion receiver for 2GHz and 5GHz. Switchable low noise amplifier is proposed for suiting for multiband (2GHz, 5GHz). Sub-harmonic mixing is used for down-conversion to minimize the DC-offset due to LO-leakage. The residual DC-offset is cancelled by a digital-to-analog converter at the output of mixer. For quadrature down-conver...

A dual-band switchable harmonic receiver for downconverting the industrial-scientific-medical and local-multipoint-distribution-service bands at 24 and 31 GHz is proposed in this paper. The front end utilizes a new technique for band selection. Mathematical formulation, including the effect of mismatches, for the new switchable harmonic receiver is provided in this paper. In addition, new circu...

A great amount of negative influence on human existence and environmental protection has been brought by heavy metal pollution in agriculture soil. Thus, major awareness diverted to the evaluation metals (EHM) agricultural land, which is used improve environment ensure people’s health. Based 3759 publications collected from Web Science Core CollectionTM (WoS), this paper’s aim illustrate a comp...
