Real Time Face Recognition Using Polynomial Regression and Sub-region Color Component Distribution

An efficient architecture for real time face recognition is presented here using Polynomial Regression for feature edge detection and by determining color-component distribution for feature-regions. Here we determine second order polynomial equation by polynomial regression for the edges of eyelid and chin. Chin does not change in different expressions, the change of eyelid is also rare and these show clear edges in the picture. For determining polynomial equations the coordinate system is very important here. The same curve may have different equations depending on the position of the curve on the graph. We have eliminated this problem. As we derive second-order polynomial equations we have three constants for each curve which we can call A, B and C. We also determine red, green and blue color-distribution values for three regions eye-region, lipregion and nose-region. For the training values related to the same person these values are averaged. Finally the recognition is performed based on the weighted sum of errors obtained from A, B, C values of the edges and color distribution values of the regions. This method is too much faster and its recognition efficiency is high
A Novel Compact Dual-band Printed Monopole Antenna

The design of an antenna, consisting of two strip monopoles printed on the same side of an electronically thin dielectric substrate and using 50 Omega microstrip feed line, is presented. The proposed antenna can provide two separate impedance bandwidth of 450 MHz (about 17.5% centered at 2.575 GHz) and 1 GHz (about 18.5% centered at 5.4 GHz) with return loss S11 below -10 dB. It easily covers the required bandwidths for wireless local area network (WLAN). The dual-band antenna is simple in design, and the lengths of the antenna's larger and smaller strips can easily control the lower and higher resonant frequencies, respectively. The widths of the radiation elements are changed to get better impedance matching. Details of the proposed antenna design and results are presented and discussed.
Efflux Pump-Mediated Intrinsic Drug Resistance in Mycobacterium smegmatis

ABSTRACT The Mycobacterium smegmatis genome contains many genes encoding putative drug efflux pumps. Yet with the exception of lfrA, it is not clear whether these genes contribute to the intrinsic drug resistance of this organism. We showed first by reverse transcription (RT)-PCR that several of these genes, including lfrA as well as the homologues of Mycobacterium tuberculosis Rv1145, Rv1146, Rv1877, Rv2846c (efpA), and Rv3065 (mmr and emrE), were expressed at detectable levels in the strain mc2155. Null mutants each carrying an in-frame deletion of these genes were then constructed in M. smegmatis. The deletions of the lfrA gene or mmr homologue rendered the mutant more susceptible to multiple drugs such as fluoroquinolones, ethidium bromide, and acriflavine (two- to eightfold decrease in MICs). The deletion of the efpA homologue also produced increased susceptibility to these agents but unexpectedly also resulted in decreased susceptibility to rifamycins, isoniazid, and chloramphenicol (two- to fourfold increase in MICs). Deletion of the Rv1877 homologue produced some increased susceptibility to ethidium bromide, acriflavine, and erythromycin. The upstream region of lfrA contained a gene encoding a putative TetR family transcriptional repressor, dubbed LfrR. The deletion of lfrR elevated the expression of lfrA and produced higher resistance to multiple drugs. Multidrug-resistant single-step mutants, independent of LfrA and attributed to a yet-unidentified drug efflux pump (here called LfrX), were selected in vitro and showed decreased accumulation of norfloxacin, ethidium bromide, and acriflavine in intact cells. Finally, use of isogenic β-lactamase-deficient strains showed the contribution of LfrA and LfrX to resistance to certain β-lactams in M. smegmatis.
How infants perceive a simple causal event

Four experiments examined 10-month-old infants'causal event perception. Experiment 1 replicated previous studies except that the specific objects used as agent and recipient varied from trial to trial. Under these conditions infants did not process the causality. Instead they keyed on specific temporal and spatial differences among the events. Experiment 2 showed that infants notice a change in the particular agent performing either a causal or noncausal action. Experiment 3 showed that infants do not notice a change in the type of action done to a particular recipient. Experiment 4 demonstrated that infants do pay attention to the object used as a recipient. As a whole, the results indicate that 10-month-old infants perceive the causality of simple events by associating a specific agent with the causal action
THE COMPOSITION ISSUE INTRODUCTION

The essays featured in this issue embrace our positions within economically accountable institutions and articulate "the labor problem" from a labor perspective. Rather than approaching Composition labor as a business management issue, they approach it as a labor issue and situate it within the contemporary labor movement. Our labor structures and the language we use to describe them are not ideologically neutral: they carry implicit values concerning people, literacy, authority and work. These essays highlight the fact that our individual and collective responses to our labor problem situate us ideologically and that ideology will likely have a great impact on the way that we will approach literacy, both in our scholarship and in the classroom.
Cerebrovascular Complications of Neck Manipulation

The safety of spinal manipulation is an issue that demands regular and rigorous assessment, as manipulation of the upper spine has been associated with serious adverse events such as cerebrovascular accidents due to cervical artery dissection. A correlation between stroke and cervical manipulation has been reported with increasing frequency, and each new report seems to reignite debate between neurologists and manual therapists. Specific risk factors for cerebrovascular complications related to spinal manipulation have not been identified yet; for this reason, any patient may be at risk, particularly those below 45 years of age. Patients undergoing spinal manipulative therapy need to consent to the possible risk of stroke or vascular injury from the procedure. Copyright © 2008 S. Karger AG, Basel
Uncomplicated Clinical Malaria Features, the Efficacy of Artesunate-Amodiaquine and Their Relation with Multiplicity of Infection in the Democratic Republic of Congo

Background In the Democratic Republic of Congo, artesunate-amodiaquine (ASAQ) is the first-line medication recommended for uncomplicated malaria treatment. We conducted a study in Kinshasa to describe the clinical features of the disease and assess the efficacy of ASAQ and its impact on the multiplicity of infection in children with uncomplicated malaria. Methods Children aged 12 to 59 months with uncomplicated P. falciparum malaria were treated with ASAQ and followed up passively for 42 days. To distinguish new infections from recrudescent parasites, samples were genotyped using a stepwise strategy with three molecular markers (GLURP, MSP2 and MSP1). We then assessed PCR-corrected and -uncorrected day-42 cure rates and multiplicity of infection (MOI). Results In total, 2,796 patients were screened and 865 enrolled in the study. Clinical features were characterized by history of fever (100%), coryza (59.9%) and weakness (59.4%). The crude and PCR-corrected efficacies of ASAQ were 55.3% (95%CI: 51.8–58.8) and 92.8% (95%CI: 91.0–94.6) respectively, as 83.6% (95%CI: 79.1–87.2) of the recurrences were new infections. Compared to monoclonal infections, polyclonal infections were more frequent at enrollment (88.1%) and in recurrences (80.1%; p = 0.005; OR: 1.8, 95%CI: 1.20–2.8). The median MOI at enrollment (MOI = 3.7; IQR: 0.7–6.7) decreased to 3 (IQR: 1–5) in the recurrent samples (p<0.001). Patients infected with a single haplotype on day 0 had no recrudescence; the risk of recrudescence increased by 28% with each additional haplotype (HR: 1.3, 95%CI: 1.24–1.44). Conclusion The PCR-corrected efficacy of ASAQ at day 42 was 92.8%, but crude efficacy was relatively poor due to high reinfection rates. Treatment outcomes were positively correlated with MOI. Continued monitoring of the efficacy of ACTs—ASAQ, in this case—is paramount. Trial Registration ClinicalTrials.gov NCT01374581
On the Librarianship of Poverty

This paper attempts to outline the main characteristics of Librarianship under the conditions ofpoverty. To the best of my knowledge and conviction, this is the base on which any meaningful discussion of Information Work in underdeveloped countries should be firmly anchored. The goal of my paper is to set up and elaborate on four principles that, in my view, determine the social relevance of Information Work in developing countries. This is a personal testament, and I hasten to add that the views expressed hereafter do not necessarily represent the official position of my employers — the Tanzania Library Service. Similarly, criticism is not directed at any particular Institution or person. Should it appear so, I offer my sincere apologies.
Entertaining Media Use and the Satisfaction of Recovery Needs: Recovery Outcomes Associated With the Use of Interactive and Noninteractive Entertaining Media

Recent research has linked the enjoyment of entertaining media to the satisfaction of intrinsic human needs (Tamborini, Bowman, Eden, Grizzard, & Organ, 2010; Tamborini, Grizzard, et al., in press). The present investigation addressed the satisfaction of recovery needs through the use of interactive and noninteractive entertaining media stimuli and the resulting recovery outcomes. In an experiment (N = 160), participants were first exposed to a working task to elicit the need for recovery and then randomly assigned to one of four experimental conditions: 1) a video game, 2) a video recording of a game, 3) an animated video clip, or 4) the control condition. The results demonstrate that interactive and noninteractive media stimuli elicit different patterns of recovery experience. Furthermore, recovery experience was significantly related to enjoyment as well as subjective (energetic arousal) and objective (cognitive performance) recovery outcomes. Enjoyment mediated the relationship between recovery experience and energetic arousal. The results demonstrate that the effects of need satisfaction associated with the use of entertaining media go beyond enjoyment and may affect recovery and psychological well being. The findings are discussed in terms of their implications for research on the recovery effects of entertaining media and for current needs-based approaches to media enjoyment.
Interference in implicit memory caused by processing of interpolated material.

This study addresses the susceptibility of implicit memory to interference. Interference is manipulated by presenting interpolated lists of words that do or do not have word stems in common with previously studied target words (e.g., target word paragraph followed by interpolated words such as paradise or vicinity). Interference in a word stem completion task occurred only when words had similar word stems (Experiment 1). Increasing the number of interpolated words with corresponding word stems (e.g., not only paradise but also parking, pardon, and parliament) produced increasing amounts of interference (Experiment 2). Interference in implicit memory appears to be a simple response competition phenomenon that occurs when cues simultaneously activate primed targets and primed competing responses. The amount of interference can be explained by a quantitative model of the relative strengths of target and competing responses.
SPINE: a framework for signaling-regulatory pathway inference from cause-effect experiments

MOTIVATION The complex program of gene expression allows the cell to cope with changing genetic, developmental and environmental conditions. The accumulating large-scale measurements of gene knockout effects and molecular interactions allow us to begin to uncover regulatory and signaling pathways within the cell that connect causal to affected genes on a network of physical interactions. RESULTS We present a novel framework, SPINE, for Signaling-regulatory Pathway INferencE. The framework aims at explaining gene expression experiments in which a gene is knocked out and as a result multiple genes change their expression levels. To this end, an integrated network of protein-protein and protein-DNA interactions is constructed, and signaling pathways connecting the causal gene to the affected genes are searched for in this network. The reconstruction problem is translated into that of assigning an activation/repression attribute with each protein so as to explain (in expectation) a maximum number of the knockout effects observed. We provide an integer programming formulation for the latter problem and solve it using a commercial solver. We validate the method by applying it to a yeast subnetwork that is involved in mating. In cross-validation tests, SPINE obtains very high accuracy in predicting knockout effects (99%). Next, we apply SPINE to the entire yeast network to predict protein effects and reconstruct signaling and regulatory pathways. Overall, we are able to infer 861 paths with confidence and assign effects to 183 genes. The predicted effects are found to be in high agreement with current biological knowledge. AVAILABILITY The algorithm and data are available at http://cs.tau. ac.il/~roded/SPINE.html.
Needs and Supports of People with Intellectual Disability and Their Families in Catalonia

BACKGROUND The study assesses the support needs of individuals with intellectual disability and their families in Catalonia. The present authors examine family quality of life (FQoL), identify the individual services required and assess families' perceptions of the extent to which their family member with intellectual disability and they themselves receive the services they need. MATERIALS AND METHODS The N&S questionnaire (Needs and Supports for people with intellectual disability and their families) was administered to 2160 families with a family member with intellectual disability aged under 70 in Catalonia (Spain). RESULTS Overall mean FQoL was quite high. FQoL was associated with family income, education, employment and percentage level of disability. Neither people with intellectual disability nor their families receive the specific support they need. CONCLUSIONS Besides providing specific support for individuals with intellectual disability, local policymakers and practitioners should apply a family-centred approach to the provision of support for families in order to improve FQoL.
Inflammatory Genes in Epicardial Fat Contiguous With Coronary Atherosclerosis in the Metabolic Syndrome and Type 2 Diabetes

OBJECTIVE To determine changes in gene expression in epicardial adipose tissue (EAT) associated with coronary atherosclerosis (CAD) and effects of pioglitazone therapy. RESEARCH DESIGN AND METHODS Genes were quantified by RT-PCR in EAT and thoracic subcutaneous adipose tissue (SAT) obtained during surgery in CAD patients with metabolic syndrome (MS) or type 2 diabetes and control subjects with minimal or no CAD and no MS or type 2 diabetes. RESULTS Increased expression of interleukin-1 receptor antagonist (IL-1Ra) and IL-10, a trend for higher IL-1β, and no change in peroxisome proliferator–activated receptor-γ (PPARγ) was found in EAT from MS or type 2 diabetes. Only PPARγ mRNA was reduced in SAT. Pioglitazone therapy in type 2 diabetes was associated with decreased expression of IL-1β, IL-1Ra, and IL-10 in EAT; decreased IL-10 in SAT; and increased PPARγ in SAT. CONCLUSIONS In MS and type 2 diabetes with CAD, proinflammatory and anti-inflammatory genes were differentially increased in EAT and selectively reduced in association with pioglitazone treatment.
A Subthreshold ARM Cortex-M0+ Subsystem in 65 nm CMOS for WSN Applications with 14 Power Domains, 10T SRAM, and Integrated Voltage Regulator

The Internet of Things (IoT) is widely predicted to comprise billions of connected devices, many of which will be wireless sensor nodes (WSN). Energy efficiency is a huge challenge here, followed by node cost and ease of software (SW) development. Addressing all of the above, this paper presents an 11.7 pJ/cycle subthreshold ARM Cortex-M0+ WSN processing subsystem implemented in low-leakage 65 nm CMOS. Voltage and frequency scalability is from 850 nW active power at 250 mV to 66 MHz above 900 mV, with a fully integrated 82% peak-efficiency voltage regulator for direct-battery operation, and supporting 80 nW CPU and RAM state-retention power gating for SW transparent leakage reduction. SW and system optimization approaches are described and a 2.94 μW SW ECG workload is presented.
Serologic Survey for Antibodies to Borrelia burgdorferi in White-tailed Deer in Ontario

Serum samples collected from 623 white-tailed deer (Odocoileus virginianus) in southern Ontario (Canada) from 1985 to 1989 were tested for antibodies to Borrelia burgdorferi using an indirect fluorescent antibody (IFA) staining method. Samples from 150 of the deer were also tested using an enzyme-linked immunosorbent assay (ELISA). At IFA titers of 1:64 and 1:128 deer with antibodies to B. burgdorferi appeared to be widespread throughout southern Ontario, with an apparent prevalence ranging from 3 to 47%. At IFA titres ≥1:256 and ELISA titres ≥1:160 deer with antibodies to B. burgdorferi were only present on Long Point which is the only known endemic focus of Ixodes scapularis, the primary vector for B. burgdorferi, in southern Ontario. At these titres the apparent prevalence of antibodies to B. burgdorferi on Long Point was only 5 to 7%, even though the mean intensity of infestation of adult I. scapularis on deer was >180, and 60% of the adult ticks are infected with B. burgdorferi. Based on these results, white-tailed deer do not appear to be a good sentinel species for the distribution of B. burgdorferi.
A study of channel estimation in OFDM systems

The channel estimation techniques for OFDM systems based on pilot arrangement are investigated. The channel estimation based on comb type pilot arrangement is studied through different algorithms for both estimating channel at pilot frequencies and interpolating the channel. The estimation of channel at pilot frequencies is based on LS and LMS while the channel interpolation is done using linear interpolation, second order interpolation, low-pass interpolation, spline cubic interpolation, and time domain interpolation. Furthermore, the channel estimation based on block type pilot arrangement is performed by sending pilots at every sub-channel and using this estimation for a specific number of following symbols. We have also implemented a decision feedback equalizer for all sub-channels followed by periodic block-type pilots. We have compared the performances of all schemes by measuring bit error rate with 16QAM, QPSK and DQPSK as modulation schemes, and multipath Rayleigh fading and AR based fading channels as channel models.

International Union of Basic and Clinical Pharmacology. LXVII. Recommendations for the Recognition and Nomenclature of G Protein-Coupled Receptor Heteromultimers

G protein-coupled receptors (GPCRs) have long been considered to be monomeric membrane proteins. Although numerous recent studies have indicated that GPCRs can form multimeric complexes, the functional and pharmacological consequences of this phenomenon have remained elusive. With the discovery that the functional GABAB receptor is an obligate heterodimer and with the use of energy transfer technologies, it is now accepted that GPCRs can form heteromultimers. In some cases, specific properties of such heteromers not shared by their respective homomers have been reported. Although in most cases these properties have only been observed in heterologous expression systems, there are a few reports describing data consistent with such heteromultimeric GPCR complexes also existing in native tissues. The present article illustrates well-documented examples of such native multimeric complexes, lists a number of recommendations for recognition and acceptance of such multimeric receptors, and gives recommendations for their nomenclature.
Diagnostic tests: III. Optimal cut-offs

Researchers inevitably ask the question what is the best cut-off? ’ As we have seen previously, applying a cut-off produces a series of diagnostic decisions (case or non-case) with two sets of outcomes – one for cases (correct or incorrect) and the converse for non-cases (incorrect or correct). These two sets are in opposition to each other because any shift in the cut-off that improves one must worsen (or leave unchanged) the other.
Optimization of multiple-channel cooperative spectrum sensing in Rayleigh fading environment

In this paper, we consider a cognitive radio network (CRN) where different secondary users (SUs) have the different detection signal-to-noise ratios for the same primary user channel in Rayleigh fading environment. We formulate the optimization problem of multi-channel cooperative spectrum sensing (CSS) to maximize the average throughput of the CRN by jointly optimizing the SUs assignment and the sensing time. Considering the optimization problem is non-convex, we transform the optimization problem to two subproblems: the SUs assignment and the sensing time setting. Specifically, a maximum cost function reduction algorithm and water-filling compensation algorithm are proposed to solve the SUs assignment. An iterative algorithm is used to optimize the sensing time. Numerical results show that the proposed algorithms can achieve the performance which is close to that of exhaustive algorithm. Moreover, the joint design can further improve the average throughput of the CRN.
