It is well-known that, in DS-CDMA downlink signal transmission, frequency-domain equalization (FDE) based on minimum mean square error (MMSE) criterion can replace rake combining to achieve much improved bit error rate (BER) performance in severe frequencyselective fading channel. However, in uplink signal transmission, as each user’s signal goes through a different channel, a severe multi-user...

This letter presents a detailed study for indoor wireless environments, where transmit power, rate and target bit error rate (BER) are varied to increase spectral efficiency. The study is conducted for the recently proposed joint fading and two-path shadowing (JFTS) channel model, which is shown to be accurate for modeling non-Gaussian indoor WLAN environments. Analysis is done for both average...

The production and characterization of a monoclonal antibody (MoAb) designated Ber-H2. directed against a new epitope of the Ki-1 (CD3O) antigen. are described. In comparison with the formerly reported Ki-1 MoAb whose reactivity with Hodgkin and Reed-Sternberg (H-RS) cells in frozen tissue sections is well-documented. the Ber-H2 MoAb showed new. important features: the labeling intensity of the...

The bit error rate (BER) performance of the asynchronous uplink channel of multicarrier code division multiple access (MCCDMA) systems with maximal ratio combining (MRC) is analyzed. The study takes into account the effects of channel path correlations in generalized frequency-selective fading channels. Closed-form BER expressions are developed for correlated Nakagami fading channels with arbit...

Abstract The use of frequency-domain equalization (FDE) based on minimum mean square error (MMSE) criterion can significantly improve the downlink bit error rate (BER) performances of DSand MC-CDMA in a frequency-selective fading channel. However, the uplink BER performance degrades due to strong multi-user interference (MUI) since different users’ signals go through different channels and henc...

We describe R&D results on optical properties of a scintillating tile//ber system for the SDC barrel electromagnetic calorimeter. The tile//ber system uses a wavelength shifting ber to readout the signal of a scintillating plate (tile) and a clear ber to transmit the signal to a phototube. In the SDC calorimeter design, four of tile//ber systems are grouped as a 22 tile package so that the gap ...

A class of generalized multicarrier direct sequence code-division multiple-access (MC DS-CDMA) schemes is defined and its performance is considered over multipath Nakagamifading channels. The spacing between two adjacent subcarriers of the generalized MC DS-CDMA is a variable, allowing us to gain insight into the effects of the spacing on the bit error rate (BER) performance of MC DS-CDMA syste...

Repair of oxidative DNA damage in mitochondria was thought limited to short-patch base excision repair (SP-BER) replacing a single nucleotide. However, certain oxidative lesions cannot be processed by SP-BER. Here we report that 2-deoxyribonolactone (dL), a major type of oxidized abasic site, inhibits replication by mitochondrial DNA (mtDNA) polymerase gamma and interferes with SP-BER by covale...

Distinguishing between reactive mesothelial proliferations and adenocarcinoma is often very difficult. Ancillary studies, in particular immunohistochemistry, are often critical in detecting malignant epithelial cells, especially in serous effusion specimens. MOC-31 and Ber-EP4 are antibodies which target the epithelial cell adhesion molecule (Ep-CAM, TACSTD1) expressed in epithelial cells, and ...

Base excision repair (BER) is a DNA repair pathway designed to correct small base lesions in genomic DNA. While DNA polymerase beta (pol beta) is known to be the main polymerase in the BER pathway, various studies have implicated other DNA polymerases in back-up roles. One such polymerase, DNA polymerase lambda (pol lambda), was shown to be important in BER of oxidative DNA damage. To further e...
