An automatic stock trading system using Particle Swarm Optimization

This paper proposes a trading strategy based on a learning method to combine a set of technical trading signals. The learning employs a modified Particle Swarm Optimization to optimize the weights of signals. The set of weighted signals is then used to determine trading decisions, i.e. to buy, to sell or to hold. A trading simulation is conducted using historical daily stock prices of twenty stocks from NYSE and SET markets. The performance is evaluated using the return on investment with the testing subset of such data. The results are compared with buy-and-hold strategy and the signal follow strategy of each individual signal.

Petrologic and crystal-chemical significance of some deep-seated phlogopitesl

Phlogopites with reverse pleochroism (a > y : B), but with rims of phlogopite with normal pleochroism (a Al > Fe3+ is assumed for tetrahedral sites, then the type of pleochroism is best correlated with overall diferences in the availability of Si + Al in kimberlite and peridotite, rather than to diferences in pp"r* between the two environments. However, some normal rims have tetrahedral-site deficiencies similar to those ofthe reverse cores, 8 - Si + Al : 0. I to 0.5, but on the basis oftheir pleochroism do not contain IV(Fe3+). All known reverse phlogopites contain Si + Al + Ti 8. This correlation suggests that the sequence of tetrahedral site preference in phlogopites is Si > Al > Ti > Fe3+. That is, normal phlogopites with Si + Al < 8 have normal pleochroism because Ti (as Ti4+? ) substitutes preferentially to Fe3+ in tetrahedral sites. Therefore, an additional requirement for the incorporation of IV(Fe3+) in phlogopite and the development of reverse pleochroism may be that Si + Al + Ti be insufficient to fill the phlogopite tetrahedra.
Assessing disability in older adults: the effects of asking questions with and without health attribution.

OBJECTIVE To determine the effects of using questions with and without health attribution on scores derived from a self-report disability instrument. METHODS We administered the disability component of the Late Life Function and Disability Instrument to 75 community-dwelling older adults. Then, we administered the same 16 questions with attribution to specific health conditions. We used a series of analytic methods including weighted Kappa coefficient, Bowker's Test of Symmetry and Rasch analysis to assess the effects of attribution formats. RESULTS A higher prevalence of disability was reported in the non-health attributed compared with the health attributed questions (t = 5.76; p < 0.001, 95% CI 3.8-7.8). Item analyses indicated that participants were significantly more likely to report disability on the non-health attributed version on 4 of the 16 questions. CONCLUSION For community-dwelling older adults, the use of a non-health attribution format may be preferable in instruments designed to assess prevalence of disability from contributing factors other than just health.
The Locrian Maidens and the Date of Lycophron's Alexandra

The tribute of two maidens to the temple of Athena in Ilium was discontinued after the end of the ‘Phocian’ war (346 B.C.). We have for this the evidence of the Epitome of Apollodorus 6. 22 χéων δ τν παρελӨντων μετ τν Φωκiκν πλεπoν ἱκτiδας πασαντo πμoντεσ. In Tzetzes' commentary to Lycophron 1. 1141 the same piece of information is given on the authority of Timaeus (pp. 335–6 Scheer = fr. 66 FHG), but Wilamowitz, among others, showed that Tzetzes arbitrarily (though perhaps not foolishly) transferred the name of Timaeus from the scholium on 1. 1155.3 The information remains valuable without the adornment of an illustrious name. We know from a story of Aelian, which ‘Suidas’ partially preserved in many fragments (Aelianus, fr. 47, Hercher, ii, p. 205), that the Locrians were compelled by the Delphic oracle to resume the interrupted practice and submitted the regulation of it to a King Antigonus, δ βασiλεὺς Ἀντγoνoς øεӨν oἱ πρσταξεκλρῳ δiακρiӨναi This King Antigonus can hardly be identified with Antigonus Doson for two reasons which must, however, be admitted to be not absolutely cogent. First, the interval between interruption and resumption would be one of more than a century, whereas Aelian (though he cannot be pressed too much on any interpretation) presupposes a shorter interval. Secondly, the ‘Lokrische Madcheninschrift’ made famous by A. Wilhelm, which is an evident terminus ante quern for the intervention of King Antigonus, can hardly be later than 230–220 B.C. Wilhelm, indeed, had suggested a date c. 270–240 B.C. His date has been affected by recent changes in Delphic chronology; but the balance of probability (so far as I can see) still favours a date nearer to 250 than to 200 B.C. Thus, the more natural alternative remains between Antigonus Monophthalmus and Antigonus Gonatas. Either agrees well with the interruption after the third Sacred War.
Optimal HAART adherence over time and time interval between successive visits: their association and determinants

Abstract We aimed to investigate the determinants of optimal highly active antiretroviral therapy (HAART) adherence and time interval between successive clinic visits, and the association between these two processes. This was done by reviewing routinely collected patient information in the Centre for the AIDS Programme of Research in South Africa (CAPRISA). Records of 688 patients enrolled in the CAPRISA AIDS treatment (CAT) programme between 2004 and 2006 were analysed. Patients were considered adherent if they had taken at least 95% of their prescribed drugs. The adherence has been measured using the pill counts data. A multivariate generalised mixed random effects approach was used to jointly analyse optimal HAART adherence and time interval between successive visits. The results showed that on the overall, the association between optimal HAART adherence and time interval between successive visits was negative. The results further showed that the interaction between time and treatment site had a significant joint effect on optimal HAART adherence and time interval between successive visits. The interaction revealed that as the number of follow-up visits increased, the interval between successive visits also increased while at the same time high levels of optimal adherence were maintained in the rural treatment site. Moreover, after accounting for the time interval between successive visits, the results showed that optimal HAART adherence was significantly associated with having a cell phone, living with a partner as well as interactions that include time and gender, time and treatment site, age and gender and age and education. The findings provide evidence of a negative association between optimal HAART adherence and the time interval between successive clinic visits on the overall, which therefore indicates that longer time interval between successive clinic visits is undesirable if optimal HAART adherence is to be maintained. This notwithstanding, rural patients were able to maintain HAART adherence for longer time interval between successive clinic visits. Furthermore, the findings indicated that optimal HAART adherence was low for some sub-populations, such as the urban and male populations, thus vigorous ongoing adherence counseling is required.
Phosphorothioate antisense oligonucleotides against basic fibroblast growth factor inhibit anchorage-dependent and anchorage-independent growth of a malignant glioblastoma cell line.

Basic fibroblast growth factor (bFGF) is a broad spectrum mitogen for many cells of neuroectodermal origin, including glial cells. The human malignant glioblastoma cell line U87-MG expresses high steady state levels of the bFGF mRNA and contains abundant stores of biologically active bFGF protein. In the present study we have examined the contribution of endogenous bFGF to the autocrine growth of these cells. Using reverse transcription-polymerase chain reaction, U87-MG cells were shown to express the mRNAs for both bFGF and the bFGF receptor, confirming the existence of the basic requirements for an autocrine loop. Addition of 5 microM bFGF-specific antisense oligonucleotide to U87-MG cultures significantly inhibited the growth rate of these cells within 48 h and blocked proliferation beyond 2 days. The corresponding bFGF-specific sense oligonucleotide did not significantly inhibit cell proliferation over the course of these experiments. Similarly, antisense oligonucleotides significantly inhibited colony formation in soft agar, while the sense sequence was without effect. Western blotting with antihuman bFGF revealed that U87-MG cells synthesize three isoforms of bFGF, approximately 18, 23, and 25 kilodaltons (kDa) in size. The 23- and 25-kDa isoforms together comprise approximately 80% of the total cellular stores of bFGF. Antisense treatment for 4 days reduced the abundance of the 23- and 25-kDa isoforms by 64-74%, but had little effect on the 18-kDa isoform. The inhibitory effect of the antisense oligonucleotides on anchorage-dependent proliferation was reversed by the addition of recombinant 18-kDa human bFGF. (ABSTRACT TRUNCATED AT 250 WORDS)
MPPT of VSCF wind energy conversion system using extremum control strategy

This paper presents the energy conversion optimization control strategy for a horizontal axis variable speed fixed pitch wind energy conversion system, which works in the partial load region. The system uses a variable speed wind turbine (VSWT), driving a squirrel-cage induction generator (SCIG) connected to a grid. Reference to the wind turbine model and its parameters are poorly known, so a new Maximum Power Point Tracking (MPPT) method is proposed based on the extremum seeking control principles. The aim is to drive the average position of the operating point near optimality. Here, the wind turbulence is used as search disturbance instead of inducing new sinusoidal search signals. The Fast Fourier Transform (FFT) processing of some available measures estimate the operating point's distance to optimality. The effectiveness of the proposed MPPT scheme is validated under different operating conditions by numerical simulations. The simulation results prove that this new approach has effectively suppressed the system vibration and enhanced system dynamic performance.
Differential sampling measurements of low-frequency sinusoidal waveforms using AC-programmable Josephson voltage standard

We have carried out the differential sampling measurements of low-frequency sinusoidal waveforms synthesis based on an AC-programmable Josephson voltage standard (AC-PJVS) system and a modified digital voltmeter. We also have performed a variety of measurements to evaluate this differential sampling technique. Evaluation results show that the overall uncertainty of this AC-PJVS system is (0.2 to 8) μV/V (k=1) for the rms amplitudes of (0.1 to 7) V with the frequency range of (1 to 500) Hz generated by the calibrators. Our measurement results above 20 Hz are in good agreement with the results obtained by the conventional method of the ac-dc transfer differences within their measured uncertainties (k=2).
Insertions of transposon Tn5 into ribosomal protein PNA polymerase operons

The genetic organization and interrelationships between the two ribosomal protein transcription units (the L11 and L10 operons) from near 89 min on the Escherichia coli chromosome were studied by using insertional mutations generated by the kanamycin-resistant transposable element Tn5. The polar effects of Tn5 insertions on the expression of the L11, L1, L10, and L12 ribosomal protein genes and the beta RNA polymerase subunit gene were examined (i) by the level of beta-galactosidase activity generated from L10-lacZ and beta-lacZ gene fusions, (ii) by direct sodium dodecyl sulfate-polyacrylamide gel electrophoresis of the proteins specified by plasmid ribosomal protein genes in UV-irradiated maxicells, and (iii) by urea-polyacrylamide gel electrophoresis of plasmid- and chromosome-specified L12 protein. The results confirmed the organization of these genes into two transcription units as follows: PL11, rplK (L11), rplA (L1), PL10, rplJ (L10), rplL (L12), rpoB (beta). ; they also localized the position of the PL10 promoter within an 80-nucleotide region near the end of the L1 gene. The results also support the idea that the translational regulatory proteins for the L11 and L10 operons are L1 and L10, respectively, and that the expression of the L12 gene is closely linked to L10 gene expression.
Cutting Edge: Antigen-Driven Lymphocyte Recruitment to the Lung Is Diminished in the Absence of Urokinase-Type Plasminogen Activator (uPA) Receptor, but Is Independent of uPA1

The requirement for urokinase plasminogen activator (uPA) and uPA receptor (uPAR) in T lymphocyte migration is unknown. uPA−/− mice have fewer pulmonary lymphocytes in response to certain infections, but its unknown whether this is due to diminished recruitment. Primed, recipient mice were IT inoculated with Ag. Three days later, fluorescently labeled lymphoblasts from background-matched control wild-type (WT), uPA−/−, or uPAR−/− donor mice were injected i.v. , and their recruitment was determined. Approximately twice the number of uPA−/− compared with WT lymphoblasts were recruited to the lungs of WT recipients. This difference was eliminated when uPA−/− and WT lymphoblasts were injected into uPA−/− recipients. Thus, the reduced number of lung lymphocytes in infected uPA−/− mice is not due to reduced recruitment. However, uPAR is critically involved in recruitment. Markedly fewer uPAR−/− compared with WT lymphoblasts were recruited to the lung. These findings suggest that uPAR may be a novel target for immune modulation in T lymphocyte-mediated disorders.
PDZ Domain-mediated Interaction of Interleukin-16 Precursor Proteins with Myosin Phosphatase Targeting Subunits*

The cytokine interleukin-16 is generated by posttranscriptional cleavage by caspase-3 of two large precursor isoforms. The smaller protein of 67 kDa (pro-IL-16) is expressed in cells of the immune system and contains three PDZ (postsynaptic density/disc large/zona occludens-1) domains, whereas the larger 141-kDa neuronal variant (npro-IL-16) has two additional PDZ domains in its N-terminal extension that interact with neuronal ion channels. Using the yeast two-hybrid approach we have identified three closely related myosin phosphatase targeting subunits, MYPT1, MYPT2, and MBS85, as binding partners of the IL-16 precursor proteins. These interactions were verified using pull-down assays, coimmunoprecipitations, and plasmon resonance experiments. Binding requires the intact PDZ2 domain of pro-IL-16 and highly related C-terminal regions in the ligands consisting of a short leucine zipper and an indispensable serine at the -1 position, suggesting a novel unconventional PDZ binding mode. Pro-IL-16 and the myosin phosphatase targeting subunits colocalize along actomyosin filaments and stress fibers in transfected COS-7 cells. By modulating and targeting the catalytic phosphatase subunit to its substrates, MYPT1, MYPT2, and MBS85 regulate various contractile processes in muscle and non-muscle cells. Our findings indicate an involvement of the IL-16 precursor molecules in myosin-based contractile processes, most likely in cell motility, providing a functional link to the chemotactic activity of the mature cytokine. Alternatively, an intracellular complex of npro-IL-16, ion channels, and components of myosin motors in neurons suggests a role in protein targeting.
Part-List Cuing of Associative Chains: Tests of Strategy Disruption

Three experiments assess the veracity of the strategy disruption explanation of part-list cuing impairment. Experiment 1 demonstrated no mnemonic detriment in recall as a result of significant disruption of the participants' self-selected forward associative seriation retrieval strategy. Experiment 2 replicated Experiment 1 while reducing overall performance levels in an attempt to reveal any possible detrimental effects. Experiment 3 ruled out 2 possible alternative explanations by demonstrating the typical part-list cuing impairment within this experimental context. It is concluded that the results challenge a strict version of the strategy disruption hypothesis.
Design of multi-sensors integrated navigation system

In order to meet the requirement of high-compact and hard-real-time outdoor navigation system, to solve the problem of invalid satellite navigation during GPS-denied period, a multi-sensors integrated navigation system is designed in this study. The system is fused with accelerometer, gyroscope, satellite receiver, binocular vision camera and barometer. The Kalman Filter, which is designed for model error estimation, fuses sensors to optimize and correct the inertial navigation error. This system is designed based on programmable SoC ZYNQ7000 which embed dual-core ARM in FPGA. One core is used for image processing and binocular vision navigation, the other is used for strapdown inertial and integrated navigation. Sensors drive control and DMA data transmission are accomplished by FPGA. Finally, an outdoor car test, which ran in high-building urban environment, verified that this integrated navigation system works stably and can be significantly applicable to real engineering project.
Comparative evaluation of frictional characteristics of coated low friction ligatures - Super Slick Ties with conventional uncoated ligatures.

BACKGROUND Elastomeric ligatures have constituted a versatile method of securing the archwire to bracket slot, though self-ligating brackets have been a recent innovation. Coating elastomeric ligatures with a hydrophobic polymeric substance has been suggested as a methodology in reducing friction at the archwire-bracket interface and in repelling salivary adherends. A new polymeric coated ligature tie - Super Slick Ties (SST), manufactured using Metafasix technology, has been marketed by TP laboratories for potential reduction in treatment time. AIM The basic in vitro design is to compare the frictional characteristics of the coated ligatures with those of uncoated ligatures in four different archwires, namely, stainless steel, NiTi, TMA, and Timolium. MATERIALS AND METHODS Four archwires used are stainless steel archwires, TMA archwires, Timolium, NiTi archwires, and two types of elastomeric ligatures (the coated and uncoated ligatures) were used. The wires used were of 0.019 × 0.025 dimension. The evaluation of friction between the brackets and the archwire was carried out as per the test protocol described by Tidy. The values for kinetic friction were obtained and tabulated. Mean and standard deviation were calculated. Paired Student's "t" test was performed to analyze the significance of difference between means. RESULTS The results indicate a significant difference in friction produced when coated and conventional uncoated ligatures were used. CONCLUSIONS SST produced lower levels of friction (11%) for all archwire materials when compared to conventional uncoated ligatures (Dispense-A-Stix) and both conventional uncoated ligatures and coated ligatures gave a rank order of coefficient of kinetic friction (μkf) among archwires, with stainless steel archwires exhibiting the least and TMA TM showing the highest.
Flow-mediated on-surface reconstitution of G-protein coupled receptors for applications in surface plasmon resonance biosensors.

To facilitate biosensor studies of G-protein coupled receptors (GPCR) and other membrane proteins, reliable methods for preparation of sensor surfaces with high protein density are required. We present here a method for the easy and rapid immobilization and reconstitution of GPCR on carboxylated dextran surfaces modified with long alkyl groups. Following amine coupling of the detergent-solubilized receptor, lipid/detergent-mixed micelles were adhered as they were injected over the immobilized surface, taking advantage of the integrated flow cells. The detergent was eluted in the subsequent buffer flow and the remaining lipid formed a bilayer on the chip surface. With this procedure, rhodopsin was functionally reconstituted in a lipid environment in approximately 1 min. This method can also be used for the easy formation of pure supported lipid bilayers for use in model membrane interaction studies.

We have compared the performances of the presented technique by measuring bit error rate with 16-QAM, 32-QAM and 64-QAM as modulation schemes.
Influence of gender and interleukin‐10 deficiency on the inflammatory response during lung infection with Pseudomonas aeruginosa in mice

Cystic fibrosis females have a worse prognosis compared to male patients. Furthermore, cystic fibrosis patients infected with Pseudomonas aeruginosa have been shown to have dysregulated cytokine profiles, as higher levels of tumour necrosis factor alpha (TNF‐α), interleukin (IL)‐8, and lower levels of IL‐10 are found in the bronchoalveolar lavage fluid compared to healthy controls. The present study was aimed at investigating the importance of gender and IL‐10 in the susceptibility of C57BL/6 mice to pulmonary infection with Pseudomonas aeruginosa. We found that wildtype females were more susceptible than males to infection, as we observed greater weight loss, higher bacterial load, and inflammatory mediators in their lungs. IL‐10 knockout mice, both females and males, had higher levels of TNF‐α in the lungs compared to wildtype mice and maintained higher levels of polymorphonuclear cells and lower levels of macrophages for a longer period of time. Our results demonstrate that the number of bacteria recovered from the lungs of IL‐10 knockout male mice was significantly higher than that observed in their wildtype male counterparts and we show that neutralization of IL‐10 in infected female mice for a prolonged period of time leads to increased susceptibility to infection. Results reported in this study clearly demonstrate that females, both wildtype and IL‐10 knockout mice are more susceptible to Pseudomonas aeruginosa infection than males, and that they mount a stronger inflammatory response in the lungs.
Graphical relevance feedback: visual exploration in the document space

We propose an interactive visualization technique for exploration of a document collection that allows the user to represent points of interest by selecting and dragging visualized objects. According to multiple points of interest, both documents and keywords are dynamically laid out on the 2D display. The user can select new points of interest with direct manipulation, having continuous visual feedback of the layout. Based on this technique, we have implemented a prototype of visual information exploration systems.
