abstract breast cancer is one of the major health problems of the eastern world. regardless of the survival rate improvement with progression in screening and adjuvant systemic therapies, still one – third of the patients with primary breast cancer have recurrence of micro metastasis after 10 years.  it is important to discover a reliable biomarker for detection of breast cancer. the underlying...

in this work, sol-gel method was used tosynthesize titanium dioxide nanoparticles (tio2). the tio2nanoparticles was characterized by scanning electron microscopy (sem), x-ray diffraction (xrd) and bet technique.the tio2 and coumarin derivative (7-(1,3-dithiolan-2-yl)-9, 10-dihydroxy-6h-benzofuro [3,2-c] chromen-6-on) were incorporated in a graphite composite electrode. the resulting modified el...

In this paper, new concatenated inner-differential space-time block code (DSTBC) and outer four-dimensional 8PSK trellis coded modulation (4D-8-PSK-TCM) encoder is designed for wireless MIMO system with Rayleigh fading noise in the absence of channel state information (CSI). The proposed concatenated encoder takes advantage of both the high coding gain from its outer-coder and the ease of the d...

In this paper several detector schemes for processing weak GPS signals in an unaided acquisition scenario are described and analyzed. Fundamental theoretical considerations based on the generalized likelihood ratio test (GLRT), as applied to GPS signal detection, are discussed. It is shown that the asymptotic version of the GLRT is equivalent to an estimator correlator (EC). For assumed determi...

This paper presents noncoherent limiter-discriminator detection and differential detection of FQPSK (Feher quadrature phase-shift-keying) with maximum-likelihood sequence estimation (MLSE) techniques. Noncoherent FQPSK systems are suitable for fast fading and cochannel interference channels and channels with strong phase noise, and they can offer faster synchronization and reduce outage events ...

 This paper presents the theoretical analysis for Noncoherent multi-tone code division multiple access (MT-CDMA) system in terms of average bit error rate (BER). The system uses differential binary phase shift keying (DBPSK) modulation and post-detection diversity combining, considering slowly Rician fading and frequency selective channel in the indoor environment. Post-detection diversity is ...

a highly sensitive differential pulse polarographic (dpp) method has been developed for the determination of trace amounts of osmium, based on the catalytic effect of osmium (viii) on the oxidation of pyrogallol red (pgr) by sodium bromate at ph 7.00 and 25.0 0.1 ? c. the reaction rate was monitored by measuring the differential pulse cathodic current of the oxidation product of pgr and bromate...
