Modelling and performances assessment of OFDM and fast-OFDM wireless communication systems.

This thesis is mainly concerned with the design, modelling and performance assessment of modulation techniques for use in wireless communication systems. The work is divided, broadly in three areas; a multimode system proposal, an assessment of a new modulation scheme and a system optimisation technique. A multimode system architecture employing GSM and EDGE systems and an Orthogonal Frequency Division Multiplexing (OFDM) system is proposed. The OFDM system is designed to have similar frame structure, channel allocation and spectrum shape to those of the GSM and EDGE systems. The multimode system is evaluated under typical multipath fading environments specified for GSM/EDGE and adjacent-channel and co-channel interference. The results indicated that the proposed OFDM system can be perfectly integrated within the GSM/EDGE network core. Furthermore, a novel modulation technique is investigated. Fast-OFDM (FOFDM) is a variation of OFDM, which offers twice the bandwidth efficiency when compared to OFDM. However, the bandwidth efficiency only applies to one dimensional modulation schemes (BPSK or M-ASK). The suitability of FOFDM for wireless communications is assessed by studying its performance under receiver front-end distortions and multipath fading environments. The performance of the FOFDM system is compared with the performance of a similar OFDM system. The results indicated that under small distortion conditions, the performance of FOFDM and OFDM is comparable. Finally, the effect of interpolation filtering on OFDM systems in noise limited and interference limited environments is investigated. The aim of this study is to highlight that interference should be taken into consideration when designing systems for wireless communications. In addition, this study can be utilised in software defined radio schemes, offering optimised performance. Overall, this thesis presents work over a range of research areas, providing system proposals, modulation comparisons and system optimisation techniques that can be used by developers of future mobile systems.
Novel mechanisms for regulating polyphosphate metabolism in Saccharomyces cerevisiae

Novel Mechanisms for Regulating Polyphosphate Metabolism in Saccharomyces cerevisiae. (May 2004) Daniel Wilhelm Neef, B.S., Valparaiso University Chair of Advisory Committee: Dr. Michael Kladde To ensure a continuous supply of phosphate, living organisms have devised complex mechanisms to regulate the uptake and subsequent utilization of this essential nutrient. An important aspect of phosphate metabolism is the storage of excess phosphate as the polymer, polyphosphate. Despite the importance of this polymer to all living organisms, much needs to be learned about its synthesis, storage, or utilization. Furthermore, little is known about the regulatory mechanisms that determine when polyphosphate synthesis or degradation is appropriate. Our work has shown that polyphosphate is a dynamic molecule whose levels fluctuate during the cell cycle. Polyphosphate levels are high in G1, and subsequently drop as the cell uses free phosphate during cell division. Mitotic induction of phosphate regulatory genes, including the acid phosphatase gene PHO5, replenishes polyphosphate levels late in the mitosis. Furthermore, we have shown that Mcm1 and Fkh1, two cell cycle dependent transcriptional activators, contribute to mitotic activation of PHO5. In addition, we have elucidated the importance of regulating polyphosphate synthesis. Strains lacking the cyclin Pho80 have increased expression of the polyphosphate synthase genes, PHM1-4, and thus have highly elevated polyphosphate levels. Hyperaccumulation of polyphosphate results in severe growth
How Do Analysts Use Their Earnings Forecasts in Generating Stock Recommendations

This paper examines whether valuation estimates based on analysts' earnings forecasts are consistent with their stock recommendations. Because earnings forecasts are linked to value and recommendations reflect analysts' opinions of value relative to current price, earnings forecasts and stock recommendations should be linked in a predictable manner. I consider four possible valuation models of how earnings forecasts and stock recommendations are linked. These models include two specifications of the residual income model, a price‐earnings‐to‐growth (PEG) model, and analysts' projections of long‐term earnings growth. The results provide little evidence that analysts' recommendations are explained by either residual income model specification. However, both the PEG model and analysts' projections of long‐term earnings growth explain analysts' stock recommendations. The relation between the valuation models and future returns is also examined. Analysts' projections of long‐term earnings growth have the great.
In vitro study of Cayratia trifolia (L.) Domin on isolated rat hemi-diaphragm by glucose uptake method

In the present investigation, Cayratia trifolia (L.) Domin, folklore antidiabetic plant, has been evaluated for its hypoglycaemic activity. This activity was studied using the glucose uptake by isolated rat hemi-diaphragm in vitro model. The powdered root of this plant was successively extracted with petroleum ether, chloroform, ethyl acetate and ethanol. Preliminary phytochemical investigations showed the presence of flavanoids in the ethanolic extract. This extract increased the uptake of glucose by isolated rat hemi-diaphragm significantly (P<0.05). It appears that the extract has direct peripheral action on glucose uptake. Results strongly suggested that C. trifolia has the potential for the treatment of diabetes mellitus caused in the consequences of resistance to stimulatory effect of insulin on GLUT-4 protein.
THE INTERACTIVE EFFECTS OF HUMAN CAPITAL, STRUCTURAL CAPITAL AND SOCIAL CAPITAL ON FIRM PERFORMANCE

Independent studies conducted on the impact of human capital, structural capital and social capital on firm performance have shown that a significant positive relationship can be established between each of them and performance. This study examined if each of these components of intellectual capital would show more significant relationships if they were to interact with each other, whether in a two-way or three-way interactions. Results provided by a sample collected from 298 business units of firms in the Malaysian financial services industry is consistent with the suggestion that the key driving forces in the contemporary business environment has moved from the management of tangible resources to the exploitation of intangible resources and differential outcome can be expected from the interactive nature of the components.

Utilisation of plant functional diversity in wildflower strips for the delivery of multiple agroecosystem services

Increased plant diversity in cropping systems can play an important role in agriculture by enhancing arthropod‐mediated ecosystem services, including biological control and pollination. However, there is limited research investigating the concurrent influence of plant functional diversity within cultivated systems on different arthropod functional groups, the provision of multiple ecosystem services, and crop yield. During a field experiment, repeated over 2 years, we measured the effect of increasing plant functional diversity on community structure of arthropod visitors, the abundance of multiple pests and induced crop damage, and fruit production in two varieties of tomato. Plant resources (floral and extra‐floral nectar and pollen) were included within experimental plots in four levels, with each level increasing the plant functional group richness, based on floral morphology and availability of resources, in a replacement series. The presence of sown flower mixtures in experimental plots was associated with increased abundance and diversity of natural enemy functional groups and an enhanced abundance of bees (Hymenoptera: Apiformes). However, we only detected relatively small variability in arthropod visitors among types of mixtures, and increased abundance of natural enemies did not translate into stronger pest suppression or reduced crop damage. Lepidoptera pest damage was significantly higher in plots adjacent to wildflower strips, an ecosystem disservice, but a significantly higher crop productivity was recorded from these plots. Our results provide evidence that inclusion of non‐crop plant resources in agroecosystems can improve the conservation of beneficial arthropods and may lead to increased crop productivity.
The nature of arsenicphytochelatin conplexes in Holcus lanatus and Pteris cretica

We have developed a method to extract and separate phytochelatins (PCs)—metal(loid) complexes using parallel metal(loid)-specific (inductively coupled plasma-mass spectrometry) and organic-specific (electrospray ionization-mass spectrometry) detection systems—and use it here to ascertain the nature of arsenic (As)-PC complexes in plant extracts. This study is the first unequivocal report, to our knowledge, of PC complex coordination chemistry in plant extracts for any metal or metalloid ion. The As-tolerant grass Holcus lanatus and the As hyperaccumulator Pteris cretica were used as model plants. In an in vitro experiment using a mixture of reduced glutathione (GS), PC 2 , and PC 3 , As preferred the formation of the arsenite [As (III) ]-PC 3 complex over GS-As (III) -PC 2 , As (III) -(GS) 3 , As (III) -PC 2 , or As (III) -(PC 2 ) 2 (GS: glutathione bound to arsenic via sulphur of cysteine). In H. lanatus , the As (III) -PC 3 complex was the dominant complex, although reduced glutathione, PC 2 , and PC 3 were found in the extract. P. cretica only synthesizes PC 2 and forms dominantly the GS-As (III) -PC 2 complex. This is the first evidence, to our knowledge, for the existence of mixed glutathione-PC-metal(loid) complexes in plant tissues or in vitro. In both plant species, As is dominantly in non-bound inorganic forms, with 13% being
GENOME ANNOUNCEMENTS Genome Sequences of Pelagibaca bermudensis HTCC2601 T and Maritimibacter alkaliphilus HTCC2654 T , the Type Strains of Two Marine Roseobacter Genera

Pelagibaca bermudensis HTCC2601 T and Maritimibacter alkaliphilus HTCC2654 T represent two marine genera in the globally signiﬁcant Roseobacter clade of the Alphaproteobacteria . Here, we present the genome sequences of these organisms, isolated from the Sargasso Sea using dilution-to-extinction culturing, which offer insight into the genetic basis for the metabolic and ecological diversity of this important group. Organisms from the Roseobacter clade of the Alphaproteobacteria are numerically signiﬁcant in the world’s oceans and have been found in a wide range of habitats (1, 3). Using previously described high-throughput dilution-to-extinction culturing (6, 13), the marine Roseobacter strains Pelagibaca bermudensis HTCC2601 T and Maritimibacter alkaliphilus HTCC2654 T were isolated in low-nutrient heterotrophic me-dium (LNHM) (4) from surface water collected at the Bermuda Atlantic Time-Series Study (BATS)
Exchange-correlation potentials in the adiabatic connection fluctuation-dissipation framework

We provide the expression of the exchange-correlation potential in the adiabatic connection fluctuation-dissipation (ACFD) framework, for arbitrary time-dependent (TD) kernels. We investigate the asymptotic behavior of the ACFD potential in three relevant approximations: the random-phase approximation, the exact-exchange kernel in two-electron systems, and the adiabatic local-density approximation. We show that these potentials have the expected -1/r+Q/r(3)-alpha/(2r(4)) tail (in closed-shell systems with spherical symmetry), where Q and alpha depend on the TD kernel and reflect the physics included in each approximation. We also discuss approximate ACFD potentials that are much simpler to compute than the exact ones while being likely of reasonable accuracy.
The Input Catalogue for the OMC camera onboard INTEGRAL

The Optical Monitoring Camera (OMC) onboard INTEGRAL (launched on October 17, 2002) has been de- signed to obtain V-Johnson photometry simultaneously with high energy observations at X-ray (3-35 keV) and gamma-ray (15 keV-10 MeV) performed by the main instruments onboard INTEGRAL. Due to technical limitations on the data process- ing electronics and the available telemetry, it is necessary to know, a priori, the objects to be monitored within the field of view (FOV) of the OMC. The OMC Input Catalogue - and subsequent updates - provides this information: astrometric and photometric reference stars for calibration and scientific targets for accurate photometric variability studies.

Cataclysmic Variables from the Sloan Digital Sky Survey. II. The Second Year

The first full year of operation following the commissioning year of the Sloan Digital Sky Survey (SDSS) has revealed a wide variety of newly discovered cataclysmic variables (CVs). We show the SDSS spectra of 42 CVs observed in 2002, of which 35 are new classifications, four are known dwarf novae (CT Hya, RZ Leo, T Leo, and BZ UMa), one is a known CV identified from a previous quasar survey (Aqr1), and two are known ROSAT or FIRST discovered CVs (RX J09445+0357, FIRST J102347.6+003841). The SDSS positions, colors, and spectra of all 42 systems are presented. In addition, the results of follow-up studies of several of these objects identify the orbital periods, velocity curves, and polarization that provide the system geometry and accretion properties. While most of the SDSS discovered systems are faint (greater than 18th magnitude) with low accretion rates (as implied from their spectral characteristics), there are also a few bright objects that may have escaped previous surveys due to changes in the mass transfer rate.
The Prognostic Significance of Intratumoral Natural Killer Cells in Colorectal Cancer

Purpose: Natural killer (NK) cells have a spontaneous cytotoxic capacity against tumor cells. NK cell infiltration is known to be related to the prognosis of colorectal cancer, but their prognostic significance has not been determined. The purpose of this study was to determine the prognostic importance of NK cell infiltration in colorectal cancer. Methods: Ninety-one patients, diagnosed with colorectal cancer, between Jan. 1994 to Dec. 1995, and consequently operated on at the Department of surgery, Korea University college of medicine, were retrospectively reviewed. Immuno-histochemical stains were performed for NK cells using the monoclonal antibody CD57 (IOT-10; 1：50 diluted; Chemicon, Temccula, U.S.A.). The intratumoral CD57 expressions were divided into 4 grades. Intensity 0 was defined as a total absence of CD57 expression in the tumor cells, Intensities 1+, 2+ and 3+ were defined as less than 25, 2550 and more than 50% expression, respectively. Consecutively, intensities 0, 1+ and 2+ were regarded as low CD57 expression, with 3+ regarded as high CD57 expression. The clinical characteristics, 5-year survival rates and recurrence rates by stage, according to the CD57 expression, were then analyzed. Results: Patients with high CD57 expression showed better survival rates and lower recurrence rates than those with low CD57 expressions (77.8 versus 53.4% and 14.8 versus 25.0%, respectively, P=0.0856). According to stage, the patient with high CD57 expressions showed better survival rates than those with low CD57 expressions in stages II and III (76.4 versus 69.9% [P=0.6802] and 66.7 versus 40.0% [P=0.4496], respectively). Conclusion: Although there was not statistical significance, these data suggest that high intratumoral infiltration of NK cells, as determined by the CD57 expression, seems to be a favorable prognostic factor in colorectal cancer, although further study will be needed.
Climatic Adaptation in Arctic and Tropical Poikilotherms

in response to white and monochromatic lights following differential adaptation of the eyes to various light stimuli. 3. The ability of Drosophila to discriminate among wave lengths is lost with a reduction of intensity to a level previously shown to involve a photoreceptive mechanism different from that shown to operate in bright light. 4. The color-differentiating capacity appears, therefore, to be associated with a high-illumination receptive mechanism (photopic) in a manner paralleling that in the vertebrate eye. 5. The dim-light receptive mechanism (scotopic) lacks color-differentiating capacity. 6. The results indicate that there are
Selective Coagulant Recovery from Water Treatment Plant Residuals Using Donnan Membrane Process

Fouling of membrane surfaces by particulate matter and large organic molecules is relatively common for pressure-driven membrane processes, namely, reverse osmosis (RO), nanofiltration (NF), and ultrafiltration (UF). Donnan membrane process (DMP) or Donnan Dialysis is driven by electrochemical potential gradient across a semipermeable ion exchange membrane. Theoretically, DMP is not susceptible to fouling by fine particulates and/or large organic molecules. According to information available in the open literature, however, DMP has not been tried to treat slurry or sludge with relatively high concentration of suspended solids or large organic molecules. This study presents the salient results of an extensive investigation pertaining to selective alum recovery from water treatment residuals (WTR) using DMP. Water treatment plants use alum, Al2(SO4)3·14H2O, as a coagulant, alum being finally converted and discharged as insoluble aluminum hydroxide along with natural organic matters (NOM), suspended solids, .
Control of cell division by nutrients, and ER stress signaling in Saccharomyces cerevisiae

Control of Cell Division by Nutrients, and ER Stress Signaling in Saccharomyces cerevisiae. (May 2007) Jinbai Guo, B.S., Northeast Agriculture University; M.S., Harbin Medical University Chair of Advisory Committee: Dr. Michael Polymenis Cell cycle progression of Saccharomyces cerevisiae cells was monitored in continuous cultures limited for glucose or nitrogen. The G1 cell cycle phase, before initiation of DNA replication, did not exclusively expand when growth rate decreased. Especially during nitrogen limitation, non-G1 phases expanded almost as much as G1. In addition, cell size remained constant as a function of growth rate. These results contrast with current views that growth requirements are met before initiation of DNA replication, and suggest that distinct nutrient limitations differentially impinge on cell cycle progression. Therefore, multiple mechanisms are hypothesized to regulate the coordination of cell growth and cell division. Genetic interactions were identified between the dose-dependent cell-cycle regulator 2 (DCR2) phosphatase and genes involving in secretion/unfolded protein response pathway, including IRE1, through a genome-wide dominant negative genetic approach. Accumulation of unfolded proteins in the endoplasmic reticulum triggers the unfolded protein response (UPR). How the UPR is downregulated is not well understood. Inositol requirement 1 (IRE1) is an endoplasmic reticulum transmembrane
