Automated LED Text Recognition with Neural Network and PCA –A Review

Light-emitting diodes text dot-matrix text (LED text) is being widely used for displaying information and announcements. LED display for modernization of society and catch on for its versatile application with many benefits. Existing paper used k-nearest neighbor(k-NN) approach, low computation complexity method for pattern recognition, is used to recognition character component as any class of character and canny edge was used to detect character pixels when appear in led display area from scene images. The drawback of existing system is that it cannot handle text line with non-uniform color and containing less than 3 characters. It also cannot detect continuous LED text. Our proposed system will utilize the probabilistic neural network (PNN) classification to add the robust classification for the higher level of the adaptiveness. Principal component analysis (PCA) is a statistical procedure that uses an orthogonal transformation to convert a set of observations of possibly correlated variables into a set of values of linearly uncorrelated variables called principal components. Our proposed system will achieve better detection and recognition rate than existing system.
Effect of Excess Lysine and Methionine on Immune system and Performance of Broilers

The present work was carried out to investigate the effects of excess dietary Lysine (Lys) and Methion ine (Met) on some blood immune parameters and the performance of broiler chicks. Three hundred male Ross 308 broile rs were allotted to five groups each of which included four replicates (15 birds per replicate) in a completel y randomized design. The treatment groups received the same basa l diet supplemented with Lys and Met (as TSAA) in 0 , 10, 20, 30 or 40% more than NRC (1994) recommendation. The collected data were analyzed by SPSS software and Duncan’s test was used to compare the means on a va lue of P< 0.05. The results indicated that the two highest levels of Lys and Met treatments (30 and 40% more t han NRC recommendation) led to significant increase in blood lymphocytes and decrease in Heterophyls and ratio oHeterophyls to Lymphocytes as a stress index (P<0 .01). There was a linear increase in Newcastle antibody p arallel with increasing dietary Lys and Met in 42 d ays of age (P<0.01) but not 21d. Carcass efficiency, breast mu scle yield, heart and liver weight were also increa sed by the two highest levels of Lys and Met (P< 0.05), whereas fe ed conversion ratio (FCR) was the least in these tw o treatment groups (P< 0.05). Addition Lys and Met 40% more tha n NRC tend to significant decrease in body weight g (P<0.05) but there was no significant effect of tre atments on thigh and leg yield. The finding of this experiment showed that increasing Lys and Met to diets of toda y’s broiler in excess of NRC recommendations can im prove immune system functions, FCR, abdominal fat deposit ion, breast meat yield and carcass efficiency. Resu lts reported here support the hypothesis that it is possible to produce more healthy and economic poultry meat by supplementation excess Lys and Met to broiler diets .
Impact of timing of nephrology referral and pre-ESRD care on mortality risk among new ESRD patients in the United States.

BACKGROUND Recent studies have suggested that early predialysis nephrological care is associated with lower mortality; however, this hypothesis has not been tested in a population-based study. We evaluated the impact of early nephrology referral and pre-end-stage renal disease (ESRD) care on mortality risk in a national cohort of new patients starting dialysis therapy in 1996 and 1997. METHODS Data were obtained on a subset of patients (n = 2,264; 56%) from the Dialysis Morbidity and Mortality Study Wave 2 who then were followed up for up to 2 years. Survival comparisons were made using log-rank test, then by Cox regression adjusting for demographics, comorbid medical conditions, and surrogate markers of pre-ESRD care. RESULTS Adjusted mortality risks (relative risks [RRs]) were higher for late- (within 4 months of dialysis initiation) compared with early-referred patients at the end of 1 and 2 years of follow-up (RR, 1.68; confidence interval [CI], 1.31 to 2.15; RR, 1.23; CI, 1.02 to 1.47, respectively). Mortality risks were similarly high for the late-referred nondiabetic (RR, 2.10; CI, 1.49 to 2.94) and hemodialysis subgroups (RR, 1.72; CI, 1.25 to 2.38). Conversely, mortality risks were lower for patients who saw a nephrologist at least twice in the year before dialysis therapy initiation (RR, 0.80; CI, 0.62 to 1.03; P = 0.08] compared with those who did not. CONCLUSION Late nephrology referral is associated with greater death risk in new patients with ESRD, and more frequent pre-ESRD care confers increased survival benefit. These findings stress the need for earlier referral of patients to nephrologists and improved pre-ESRD care for all patients approaching ESRD in the United States to improve survival.

Nathaniel Branden’s Legacy to the Science of Clinical Psychology

This article presents a summary of the key aspects of the Biocentric theory of psychology proposed and developed by Nathaniel Branden. The themes of the conscious and nonconscious aspects of the mind and their interplay in healthy and psychopathological human functioning are highlighted, with the development and maintenance of self-esteem as the centerpiece of this schema. Branden’s cogent, in-depth analysis and synthesis of these issues, presented for the first time over fifty years ago, is discussed in relation to issues that are being actively researched today.
Distribution of gamma-aminobutyric acid-immunoreactive neurons in the septal region of the rat brain.

The distribution of gamma-aminobutyric acid-immunoreactive (GABA-I) elements was examined in the septal region of the rat brain. The indirect peroxidase-antiperoxidase technique was used with anti-GABA antibodies in normal and colchicine-pretreated rats, with or without use of detergent in the incubation medium. Intraventricular injection of colchicine did not result in any change in the staining of neuronal perikarya. Intraseptal injections increased the intensity of labelling of GABA-I cell bodies in the lateral septal nucleus and increased the number of labelled cells in the medial septal nucleus and diagonal band of Broca (dbB). Triton X-100 added to the incubation media decreased the intensity of staining and number of GABA-I somata in all septal nuclei with a concentration-dependent effect. No change was observed concerning GABA-I varicosities. The septal area, including the lateral, medial, and triangular septal nuclei; the anterior rudiment of the hippocampus; the island of Calleja magna; the septofimbrial nucleus; the bed nucleus of the stria terminalis; and the dbB showed a strong reaction to anti-GABA antibodies with regard to GABA-containing surrounding structures. GABA-I axonal varicosities were observed in all the regions with an uneven distribution. The highest density was found in the dorsal and ventral parts of the lateral septal nucleus and in a band situated between the dbB and the nucleus accumbens. Labelled varicosities were frequently observed surrounding GABA-I and nonimmunoreactive cell bodies. GABA-I somata ranged from 10 to 30 micron in diameter. Small neurons were present in great number at the ventricular border and in the zona limitans. Medium-size and large neurons were mostly observed in the medial part of the dorsal lateral nucleus and in the intermediate lateral nucleus. (ABSTRACT TRUNCATED AT 250 WORDS)
Analysis of spontaneous, gamma ray- and ethylnitrosourea-induced hprt mutants in HL-60 cells with multiplex PCR.

AIM To explore the molecular spectra and mechanism of human hypoxanthine guanine phosphoribosyl transferase (hprt) gene mutation induced by ethyluitrosourea (ENU) and (60)Co gamma-rays. METHODS Independent human promyelocytic leukemia cells (HL-60) mutants at the hprt locus were isolated from untreated, ethyluitrosourea (ENU) and (60)Co gamma-ray-exposed cells, respectively, and verified by two-way screening. The genetic changes underlying the mutation were determined by multiplex polymerase chain reaction (PCR) amplification and electrophoresis technique. RESULTS With dosage increased, survival rate of plated cell reduced (in the group with dosage of ENU with 100-200 micro g/ml, P<0.01; in the group with dosage of (60)Co gamma-ray with 2-4 Gy, P<0.05) and mutational frequency increased (in the group of ENU 12.5-200.0 micro g/ml, P<0.05; in the group of (60)Co gamma-ray with 1-4 Gy, P<0.05) significantly. In the 13 spontaneous mutants analyzed, 92.3 % of mutant clones did not show any change in number or size of exon, a single exon was lost in 7.7 %, and no evidence indicated total gene deletion occurred in nine hprt exons. However, deletions were found in 79.7 % of ENU-induced mutations (62.5-89.4 %, P<0.01) and in 61.7 % of gamma-ray-induced mutations (28.6-76.5 %, P<0.01). There were deletion mutations in all 9 exons of hprt gene and the most of induced mutations were chain deletion with multiplex exons (97.9 % in gamma-ray-induced mutants, 88.1 % in ENU-induced mutants). CONCLUSION The spectra of spontaneous mutations differs completely from that induced by EUN or (60)Co gamma-ray. Although both ENU and gamma-ray can cause destruction of genetic structure, mechanism of mutagenesis between them may be different.
Analysis of Thermal Radiation Properties of Polyimide and Polymeric Materials Based on ATR-IR spectroscopy

A facile and non-distractive method for estimating thermal emissivity of solid polymers based on ATR-FT-IR method was newly developed. This method is applicable to thick and nontransparent samples without using blackbody furnace. The thermal emissivity estimated by this method is consistent with the reference values obtained using blackbody furnace. The ATR-IR method enables to estimate thermal emissivity of polymer materials having arbitrary shapes not only bulk and films but also forms and fabrics.
Deviant Cloud Usage in Public Institutions - a Matter of Personal Innovativeness?

The emergence of cloud services offered many benefits for less tech savvy individuals, because it offers easy accessible computing or storage solutions for every customer. The adoption among individuals surpassed the adoption by organizations like businesses or public institutions due the tremendous benefits of cloud services for customers. Due the lacking adoption by public institutions, we see an increasing deviant use of such services in environments, where the IS policy actually prohibits a use of not approved third-party service. Current research has only a basic understanding on what drives the deviant cloud usage within organizations and the apparent influence of personality traits on the usage of Shadow IT has not been evaluated, yet. It is expectable that individuals with an affinity towards IT innovations use information systems before they are approved by organizational IS security policies and not users reluctant towards technology. A granular knowledge of different types of deviant users is helpful in order to develop strategies to address specific mechanisms of justifying violations of IS policies by using not approved cloud services. Our preliminary findings among public officials show that users with a high personal innovativeness are less likely to behave in compliance to the IS security policy.
Using Twitter and other social media platforms to provide situational awareness during an incident.

The recent use of social media by protesters in Iran, Egypt, Yemen and elsewhere has focused new attention on this communications medium. Government agencies and businesses, as well, are using social media to push information to their stakeholders. Those who are on the front lines of this information revolution, however, realise that social media is most effective when the communication is two-way. Unlike other media, social media allows information sharing. This, in turn, provides emergency managers with new situational-awareness resources when trying to mitigate an incident. As Federal Emergency Management Agency (FEMA) Administrator Craig Fugate told Information Week on January 19th, 2011: 'We can adjust much quicker if we can figure out how to have (a) two-way conversation and if we can look at the public as a resource. The public is putting out better situational awareness than many of our own agencies can. ' This paper provides examples of how social media can be used as a situational-awareness resource and specific 'tools' that can be used to assist with this task.
Influence of alginate cross-linking method on neurite response to microencapsulated neurotrophin-producing fibroblasts

Transplantation of cells genetically modified to produce neurotrophins is a promising spinal cord repair strategy. Previously we showed that fibroblasts engineered to produce brain-derived neurotrophic factor (Fb/BDNF) microencapsulated in alginate survive, continue to grow and express bioactive BDNF. We here compared the effects of different alginate crosslinkers on dorsal root ganglia (DRG) neurite growth using alginate-encapsulated Fb/BDNF. Aqueous sodium alginate (±Fb/BDNF) was contacted with different calcium salts, and used as substrate for DRG growth. Length, number and orientation of neurites were measured. Chloride or carbonate salts promoted significantly more neurite growth than sulphate, with or without Fb/BDNF, although encapsulated Fb/BDNF stimulated significantly more neurite growth than cell-free. An Fb/BDNF-derived neurotrophin concentration gradient directionally guided DRG neurite growth. This positive effect of alginate-encapsulated Fb/BDNF on neurite growth/guidance shows promise for enhanced regeneration and guidance of axons towards a specific target in the injured spinal cord.
Exacerbation of Perihematomal Edema and Sterile Meningitis With Intraventricular Administration of Tissue Plasminogen Activator in Patients With Intracerebral Hemorrhage

OBJECTIVEIntraventricular hemorrhage (IVH) is associated with a poor outcome. External ventricular drainage together with clot lysis through intrathecal tissue plasminogen activator (IT-tPA) has been proposed as a promising therapy. However, recent experimental work has implicated tissue plasminogen activator (tPA) in the pathogenesis of cerebral edema. METHODSWe reviewed the records of all patients with IVH caused by primary supratentorial intracerebral hemorrhage who underwent external ventricular drainage without surgical evacuation between January 2001 and June 2008. Of these 30 patients, we identified 13 who received IT-tPA. The remaining 17 patients served as controls. Hemorrhage, edema volume, and IVH score were determined on admission and by follow-up computed tomographic scans for 96 hours after admission. Discharge outcome was evaluated using the modified Rankin Scale. RESULTSThere were no significant differences between the treatment and controls in terms of age, Glasgow Coma Scale score, Graeb and LeRoux IVH scores, or intracerebral hemorrhage volume on admission. IT-tPA resulted in more rapid clearance of IVH as determined by the 96-hour decrease in both the Graeb IVH score (tPA, 3.00 ± .55; control, 1.00 ± 0.57; P = .05) and the LeRoux IVH score (tPA, 6.2 ± 0.80; control, 2.25 ± 1.32; P = .05). Patients treated with IT-tPA demonstrated significantly larger peak ratios of edema to intracerebral hemorrhage volume (1.24 ± 0.14 vs 0.70 ± 0.08 in controls; P = .002). Additionally, increased rates of sterile meningitis (46% vs 12%; P = .049) and a trend toward shunt dependence (38% vs 6%; P = .06) were observed in the tPA cohort. Nevertheless, no significant differences in outcome at discharge or length of hospital stay were observed between cohorts. CONCLUSIONAlthough IT-tPA hastens the resolution of IVH, it may worsen perihematomal edema formation. Larger prospective studies are required to confirm these findings and to determine whether outcome is adversely affected by IT-tPA administration.
Study on vector control for double-fed induction machine with stator windings short circuited

Starting up and/or low speed operations are imperative for double-fed induction machine (DFIM) in DFIM-based driving system or DFIM-based wind turbine system under low speed wind conditions. Compared with others, the rotor-side driving control strategy with stator-winding short circuited can operate DFIM, without extra equipments, at low speed very well. The operation theory is analyzed, based on which the equivalent circuits and the corresponding mathematical models are presented and discussed. According to the models, built in the paper, vector control for rotor-side driving control strategy is proposed, with which, the decoupled control between the torque current component and the excited current component of DFIM rotor currents is achieved. As result, the dynamic and stable control performances of DFIM-based systems are improved. To validate the proposed control strategy, a 2MW DFIM-based driving system is simulated.
Research on the application of gasoline endpoint soft-sensing in hydroforming unit based on SVM

The application of Support Vector Machines(SVM) to the soft-sensing modeling technology was studied. To solve the problem that the endpoint of a refinery hydroforming unit can't be monitored real-time on line, the soft-sensing model based on SVM was established and the gasoline endpoint was predicted. The experimental results show that the model has some characters such that quick calculating rate and high forecast accuracy. The indices are satisfied with the user's requirements, and the predicting effects are good in the practice.
The visfatin gene is associated with glucose and lipid metabolism in a Chinese population

Aims Visfatin is a newly discovered adipokine found in abundance in visceral fat. It lowers plasma glucose in humans and mice. In this study, we explored the relationships between the plasma level of visfatin and genetic single nucleotide polymorphisms (SNPs) and Type 2 diabetes mellitus (T2DM) and anthropometric and metabolic parameters in Chinese subjects.
Delivery to cancer cells of antisense L‐ myc oligonucleotides incorporated in fusogenic, cationic‐lipid‐reconstituted influenza‐virus envelopes (cationic virosomes)

Antisense oligodeoxy‐nucleoside phosphorothioates (OPTs) of L‐myc were encapsulated into reconstituted influenza‐virus‐A envelopes (virosomes). The envelopes of the virosomes consisted of a single positively charged (cationic) lipid bilayer. Binding of cationic virosomes to cellular receptors that are membrane glycoproteins or glycolipids containing terminal sialic acid is mediated by the hemagglutinin glycoprotein (HA) of the influenza virus. After internalization through receptor‐mediated endocytosis, cationic virosomes fuse efficiently with the membranes of the endosomal‐cell compartment, and as a consequence the encapsulated OPT are delivered to the cell cytoplasma. Examination by fluorescence microscopy of the cellular uptake of cationic virosomes containing fluorescein‐labeled OPT showed rapid and efficient incorporation of virosomes. Addition of cationic virosomes (75–150 μl) containing antisense L‐myc OPT in the picomolar range to small‐cell‐lung‐cancer (SCLC) cell cultures that expressed highly the L‐myc oncogene led to strong inhibition of thymidine incorporation in a concentration‐dependent manner. Virosome‐entrapped sense L‐myc OPT and random‐order OPT had only minimal effects on the thymidine uptake. Cells of SCLC cell line NCI‐H82 expressing a very low level of L‐myc were not affected by antisense‐L‐myc virosomes. In Western‐blot analysis, expression of L‐myc protein was suppressed in the antisense‐virosome‐treated NCI‐H209 cells but not in untreated control NCI‐H209 cells. These results suggest that cationic virosomes may have great potential as an efficient delivery system for antisense oligonucleotides in cancer therapy. Int. J.

Keep music live: music and the alleviation of apathy in dementia subjects

Background: A recent Cochrane report concluded that more and better quality research is required to investigate the effectiveness of music therapy in reducing problems in behavioral, social, emotional and cognitive domains in patients with dementia. This randomized placebo-controlled trial with blinded observer rater aimed to explore whether music, live or pre-recorded, is effective in the treatment of apathy in subjects with moderate to severe dementia. Methods: Thirty-two subjects meeting ICD-10 diagnostic criteria for moderate to severe dementia and fulfilling diagnostic criteria for apathy were exposed to live interactive music, passive pre-recorded music or silence for 30 minutes. Each subject was randomized to 30-minute music or silent periods and was video recorded and the muted recording analyzed every 3 minutes using dementia care mapping to assess the quality of engagement to the blinded music intervention. Results: Compared to low baseline levels of positive engagement (12.5%) in the silent placebo period, the majority of subjects (69%), regardless of dementia severity, showed a significant and positive engagement to live music. Engagement to pre-recorded music was non-significant, with just 25% of all subjects showing positive engagement. No subjects showed any evidence of experiencing a state of ill-being during either the live or pre-recorded music sessions. Conclusions: During the intervention, live interactive music has immediate and positive engagement effects in dementia subjects with apathy, regardless of the severity of their dementia. Pre-recorded music is non-harmful but less clearly beneficial.
Legume and isoflavone intake and prostate cancer risk: The Multiethnic Cohort Study

Findings from studies of legume, soy and isoflavone intake and prostate cancer risk are as yet inconclusive, although soy has received considerable attention due to its high phytoestrogen content. Therefore, the present study investigated the relationship of these dietary exposures to prostate cancer risk in the Multiethnic Cohort Study in Hawaii and Los Angeles. The analyses included 82,483 men who completed a detailed quantitative food frequency questionnaire in 1993–1996. A total of 4,404 prostate cancer cases including 1,278 nonlocalized or high‐grade cases were recorded during the average follow‐up period of 8 years. Multivariate relative risks (RR) and 95% of confidence intervals (CI) were estimated using Cox proportional hazards models with age as the time metric. Among men with the highest intake of legumes, the risk reduction was 11% for total prostate cancer (RR = 0.89, 95% CI = 0.80–0.99, p for trend = 0.007) and 26% for nonlocalized or high‐grade cancer (RR = 0.74, 95% CI = 0.61–0.90, p for trend = 0.007) compared to men with the lowest intake. Similar risk reductions were observed for soy products and for legumes excluding soy products in separate analyses. We found no significant risk reduction associated with intake of total or specific isoflavones for either total prostate cancer or for nonlocalized or high‐grade cancer. The findings of our study suggest that legume intake is associated with a moderate reduction in prostate cancer risk and that the isoflavones in soy products are probably not responsible for this effect. © 2008 Wiley‐Liss, Inc.
