This paper presents a unified analysis for the downlink BER performance of convolutionally coded and single-user detected MC-CDMA, MCDS-CDMA and TFL-CDMA. As a special case, an analysis is obtained also for OFDMA. The intra-cell interference is analyzed under the assumption of Hadamard spreading codes and a correlated frequency-selective Rayleigh-fading channel. The presented results assume err...

Osteonecrosis of femoral head is a painful disabling condition seen in association with many disorders like corticosteroids consumption, alcohol abuse, haemoglobinopathy (sickle cell disease, coagulopathies), certain renal, hepatic and skin disorders commonly affecting young patients ranging from 20-40 years.1-3 It is now recognized as a major musculo-skeletal problem mostly affecting the young...

INTRODUCTION Clinically, there has been an interest in the relationship between hip and spine function since the first reporting of hip-spine syndrome [1]. This work discussed the effects of a pathological hip joint on spine function. Others [2,3] have suggested an association between low back pain (LBP) and gluteal muscle inhibition as part of the functional presentation in some patients with ...

With the acceleration of its internationalization, China is faced with epochal task optimizing international-standard linguistic environment, which especially impending for Chengdu, host city Universiade. The neo-analysis, at first, sorts out and analyzes different versions official translation norms toponyms through document research, as well from first-hand resources on public signs rail tran...

Chicken ovalbumin upstream promotor-transcription factor I (COUP-TFI), an orphan member of the nuclear receptor superfamily, is highly expressed in the developing nervous systems. In the cerebral cortex of Coup-tfl mutants, cortical layer IV was absent due to excessive cell death, a consequence of the failure of thalamocortical projections. Moreover, subplate neurons underwent improper differen...

The aim of this study was to describe de fiber composition in the thigh muscles of grass cutter (Thryonomys swinderianus, Temminck 1827). Ten 4 to 6-month-old (3 to 4 kg) male grasscutter were used in this study. Eleven skeletal muscles of the thigh [M. biceps femoris (BF), M. rectus femoris (RF), M. vastus lateralis (VL), M. vastus medialis (VM), M. tensor fasciae latae (TFL), M. semitendinosu...

The limbic system has been implicated in the modulation of pain. The aim of this study was to determine the role of amygdala in different types of pain, viz., phasic and tonic. Unilateral stimulation of central nucleus of amygdala (CeA), basolateral nucleus (BL) and medial amygdaloid (MeA) in conscious rats resulted in the reduction of the tonic formalin-induced pain. The thresholds for simple ...

My contribution to the session at the New Orleans meetings of the Assocation of American Geographers at which the ideas that appear in this forum were initially aired was as discussant, following the three main presentations by Barnes, Miller, and Smith. This paper expands on the comments I made during the session, and include reactions to the subsequent contribution of Phillips. Specifically, ...
