Recognizing the ID of modulated LED tube lights by using camera motion blur
Authors: Li Chang , Iwai Daisuke , Sato Kosuke 
Published: November 2012

AbstractIn this paper, we present an image‐based ID recognition method for ID‐modulated light‐emitting diode (LED) tube lights by using the motion blur captured by a moving camera. This method is applied to a novel camera‐based indoor positioning system, which can provide exact location for mobile users. In this system, high‐intensity LED tubes are used concurrently as the illumination devices and optical markers. The flashing of each LED lamp is modulated, and the entire tube expresses an ID message, which can be captured by a normal camera installed in a mobile terminal. The flashing occurs at a high frequency and without degrading the illumination function. However, when the exposure time of the camera is longer than the flicker period of the LED lamps, it is difficult to capture the ID pattern. We propose a method that uses motion blur to overcome this limitation. During the period of exposure, if the user manually shakes the camera in the proper direction, a streaked pattern is developed on the captured image frame, which can be used for retrieving an ID number. Moreover, we can also obtain position estimation of the terminal from motion‐blurred images. Experimental results show that with careful operation it is feasible to recognize the ID of LED tubes successfully. © 2012 Institute of Electrical Engineers of Japan.

A starting method of the harmonic current compensator using a hybrid active filter for wind power generation systems with soft starters
Authors: Yamada Hiroaki , Hiraki Eiji , Tanaka Toshihiko 
Published: November 2012

AbstractThis paper proposes a starting method of the harmonic current compensator using a hybrid active filter for wind power generation systems. The active filter (AF) in the proposed method of the hybrid power filter behaves as a resistor and reactive power compensator to suppress the inrush current and leading currents for the passive filter (PF) under the starting condition. The basic principle of the proposed starting method is discussed, and then confirmed by digital computer simulation using PSCAD/EMTDC. Simulation results demonstrate that the proposed starting method can overcome the inrush and leading currents for the PF, building up the DC capacitor voltage of the AF.

Experience With Recurrent Respiratory Papillomatosis in a Developing Country: Impact of Tracheostomy
Authors: Orji Foster Tochukwu , Okorafor Ijeoma A. , Akpeh James O. 
Published: November 2012

AbstractBackgroundThe frequent relapses of recurrent respiratory papillomatosis (RRP) sometimes demand repeated surgical excision with tracheostomy. This situation plays a vital role in the management of RRP in developing countries such as ours because of late presentation. This study was conducted to evaluate our experience with RRP and to determine the incidence and impact of tracheostomy in the overall management and outcomes of our patients.MethodsThe records of 59 patients with histologically confirmed RRP treated between 1994 and 2008 at our tertiary institution were reviewed. We collected data such as age at onset, tracheostomy frequency and duration, number of required surgical excisions, papilloma spread to the lower airways. Patients’ characteristics and the course of the disease were compared between a juvenile‐onset papillomatosis (JoRRP) group and an adult‐onset group (AdRRP).ResultsOverall, 68 % of our patients were in the JoRRP group (ages 2–11 years, mean 6 years). The other 32 % were 22–58 years of age (AdRRP group). Two cases of JoRRP continued into adult life. Multiple RRP dominated in the JoRRP group (93 %), whereas solitary papillomas predominated in the AdRRP group (63 %). Tracheostomy was performed because of upper airway obstruction in 42 % of our patients, with children accounting for 72 %. The mean duration of tracheostomy was 3.5 months, with 80 % lasting <4 months. Significantly more JoRRP patients had severe upper airway obstruction, required tracheostomy, and underwent multiple surgical excisions (p = 0.04, 0.02, and 0.009, respectively). Tracheobronchial spread occurred in a patient with prolonged tracheostomy.ConclusionsMultiple laryngeal papillomatosis clearly followed a more severe and less predictable course than the solitary type in both groups. Although there was a high incidence of tracheostomy in this study, short‐duration tracheostomies accounted for the low incidence of extralaryngeal spread.
A Novel Gaussian Extrapolation Approach for 2D Gel Electrophoresis Saturated Protein Spots

Published: November 2012

Abstract
Analysis of images obtained from two-dimensional gel electrophoresis (2D-GE) is a topic of utmost importance in bioinformatics research, since commercial and academic software available currently has proven to be neither completely effective nor fully automatic, often requiring manual revision and refinement of computer generated matches. In this work, we present an effective technique for the detection and the reconstruction of over-saturated protein spots. Firstly, the algorithm reveals overexposed areas, where spots may be truncated, and plateau regions caused by smeared and overlapping spots. Next, it reconstructs the correct distribution of pixel values in these overexposed areas and plateau regions, using a two-dimensional least-squares fitting based on a generalized Gaussian distribution. Pixel correction in saturated and smeared spots allows more accurate quantification, providing more reliable image analysis results. The method is validated for processing highly exposed 2D-GE images, comparing reconstructed spots with the corresponding non-saturated image, demonstrating that the algorithm enables correct spot quantification.
Are all experiences of fit created equal? Two paths to persuasion
Authors: Avnet Tamar , Laufer Daniel , Higgins E. Tory 
Published: November 2012

AbstractRegulatory fit influences the effectiveness of persuasion through two paths: 1) a “feeling right” as “feeling good about the target” effect where feeling right is a positive feeling that transfers positivity directly to the target, similar to “feelings as information” or fluency effects, and 2) a “feeling right” as “feeling confident about the evaluation” effect where feeling right is feeling confident about one's evaluative judgments of the target that increases reliance on those evaluations. We propose that the involvement with an attitude‐related issue in a persuasion message is one key factor that determines when each effect will occur. Five studies demonstrate that under high involvement, fit increased reliance on evaluative reactions to the target, making a target of a positive advocacy message evaluated as more positive and a target of a negative advocacy message evaluated as more negative; and under low involvement, fit increased the positivity of feelings toward the target regardless of the valence of the message advocacy, making the evaluation of the target more positive for either a positive or negative advocacy message.
Malleable conjoint partworths: How the breadth of response scales alters price sensitivity
Authors: Chakravarti Amitav , Grenville Andrew , Morwitz Vicki G. , Tang Jane , Ülkümen Gülden 
Published: November 2012

AbstractIn one laboratory study and one field study conducted with a large, representative sample of respondents, we show that seemingly innocuous questions that precede a conjoint task, such as demographic and usage‐related screening questions can alter the price sensitivities recovered from the main conjoint task. The findings demonstrate that whether these prior questions use broad response categories (i.e., few scale points) or narrow response categories (i.e., many scale points) systematically influences consumers' price sensitivity in a CBC (Choice Based Conjoint) study. We suggest that this may occur because the narrow (vs. broad) response categories in the prior questions lead to consideration of a greater (vs. fewer) number of attributes during the key conjoint task. Since both groups of consumers readily consider the naturally salient price attribute, responding to previous questions with narrow (vs. broad) response categories leads to a greater (vs. fewer) number of non‐price attributes being considered, and consequently, decrease the weight afforded to price and reduce price sensitivity.

Experiments were performed to evaluate the hypothesis that ACE (angiotensin-converting enzyme) inhibition (enalapril) suppresses 3-NT (3-nitrotyrosine) production in the renal cortex during the early stage of Type 1 DM (diabetes mellitus) in the rat. Enalapril was administered chronically for 2 weeks to subsets of STZ (streptozotocin)-induced DM and vehicle-treated sham rats. O2− (superoxide anion) and NOx (nitrate+nitrite) levels were measured in the media bathing renal cortical slices after 90 min incubation in vitro. SOD (superoxide dismutase) activity and 3-NT content were measured in the renal cortex homogenate. Renal cortical nitrated protein was identified by proteomic analysis. Renal cortical production of O2− and 3-NT was increased in DM rats; however, enalapril suppressed these changes. DM rats also exhibited elevated renal cortical NOx production and SOD activity, and these changes were magnified by enalapril treatment. 2-DE (two-dimensional gel electrophoresis)-based Western blotting revealed more than 20 spots with positive 3-NT immunoreactivity in the renal cortex of DM rats. Enalapril treatment blunted the DM-induced increase in tyrosine nitration of three proteins ACO2, GDH1 and MMSDH (aconitase 2, glutamate dehydrogenase 1 and methylmalonate-semialdehyde dehydrogenase), each of which resides in mitochondria. These data are consistent with enalapril preventing DM-induced tyrosine nitration of mitochondrial proteins by a mechanism involving suppression of oxidant production and enhancement of antioxidant capacity, including SOD activation.
How Do Biofuel Use Mandates Cause Uncertainty? United States Environmental Protection Agency Cellulosic Waiver Options
Authors: Meyer Seth , Thompson Wyatt 
Published: November 2012

AbstractBiofuel policy in the United States sets minimum use mandates for different biofuels, but the cellulosic mandate, introduced in 2010 has been waived and reduced to nearly zero since then. This waiver has shifted the burden of compliance to other biofuels, but other options exist. We examine some alternatives using a structural model of biofuel, agricultural, and mandate markets. Our estimates show that crop price levels, crop and livestock farm income, compliance costs, and greenhouse gas emissions are all sensitive to whether and how the cellulosic mandate is waived. Mandate analysis that does not consider Environmental Protection Agency implementation, or waiver analysis that disregards the hierarchical nature of the mandates could be misleading.
Evidence of accretion triggered oscillations in the pre-main-sequence interacting binary AK Sco
Authors: Gómez de Castro Ana I. , López-Santiago Javier , Talavera Antonio 
Published: November 2012

Abstract
Pre-main sequence (PMS) binaries are surrounded by circumbinary discs from which matter falls on to both components. The material dragged from the circumbinary disc flows on to each star through independent streams channelled by the variable gravitational field. The action of the bar-like potential is most prominent in high eccentricity systems made of two equal mass stars. AK Sco is a unique PMS system composed of two F5 stars in an orbit with e = 0.47. Henceforth, it is an ideal laboratory to study matter infall in binaries and its role in orbit circularization. In this Letter, we report the detection of a 1.3 mHz ultra low-frequency oscillation in the ultraviolet light curve at periastron passage. This oscillation lasts 7 ks being most likely fed by the gravitational energy released when the stream's tails spiralling on to each star get in contact at periastron passage enhancing the accretion flow; this unveils a new mechanism for angular momentum loss during PMS evolution and a new type of interacting binary.

Saponaria officinalis L. (Caryophyllaceae; also known as bouncingbet or soapwort) is a perennial medicinal plant important for the pharmaceutical industry and used as an expectorant, alterative, laxative, and ointment for some skin diseases and arthritic conditions. S. officinalis plants with typical symptoms (23% in 2011 and 47% in 2012) of phytoplasma infection were observed in Pancevo plantation, Serbia. The symptoms appeared in May with leaves changing color from green to brown with severe reddening and necrosis. Severely diseased plants died. The infected plants had a significant reduction in biomass and quality. To investigate the presence of phytoplasma, total DNA was extracted from 10 symptomatic and four asymptomatic plants by a CTAB method. The nested PCR was carried out using phytoplasma-specific primer set P1/16S-SR followed by R16F2n/R16R2, targeting the 16S rRNA gene sequence of 1.5 and 1.2 kb in length, respectively. The amplicons of expected size were obtained from the symptomatic plants, but not from the asymptomatic plants. To obtain restriction fragment length polymorphism (RFLP) patterns, the R16F2n/R2 amplicons were digested with AluI, TruI1, HpaII, and HhaI endonucleases. The resulting patterns indicated that seven plants were infected by a Stolbur phytoplasma belonging to the 16SrXII-A subgroup, since it had the identical RFLP pattern as the STOL reference strain. The 1.2 kb nested PCR products of representative isolate Sap7 were purified using PCR purification kit (Fermentas, Vilnius, Lithuania) according to the recommended protocol and sequenced using facilities of IMGGI SeqService, Belgrade, Serbia. The obtained sequence was deposited in the NCBI database (GenBank Accession No. JX866951). The phytoplasma 16S rRNA gene sequence from Sap7 had a sequence identity of 97% with GenBank accessions GQ273961.1 (‘Euonymus japonicus’ phytoplasma), JX311953.1 (Candidatus Phytoplasma solani clone 5043), JQ412100.1 (Iranian alfalfa phytoplasma M21), and JN561702.1 (‘Convolvulus arvensis’ stolbur phytoplasma clone P1/P7-Conv2/2010-Bg). To our knowledge, this is the first report of a natural infection of S. officinalis by 16SrXII-A subgroup (Stolbur) phytoplasma in Serbia. As cited by Lee et al. (1), the 16SrI-M subgroup phytoplasma in S. officinalis sample was already detected in Lithuania by Valiunas (2). The identification of phytoplasma in the Pancevo plantation caused the intensification of our biological control tests and efforts to reduce the ecological and economic impacts of these phytoplasmas.

The fatty acid profiles of Chinese Maiwa yak milk samples were evaluated at different seasons (n = 96) and parities (n = 32). Saturated fatty acid content and monounsaturated fatty acid content showed no significant difference (P > 0.05) between warm season and cold season; however, polyunsaturated fatty acid (PUFA) content in warm season was higher (P < 0.05) than in cold season. Monounsaturated fatty acid and PUFA contents were higher (P < 0.05) in multiparous Maiwa yak milk than in primiparous Maiwa yak milk. Trans‐11C18:1, cis‐9, cis‐12C18:2, CLA and C18:3 contents were higher (P < 0.05) in multiparous Maiwa yak than in primiparous Maiwa yak milk.
Arthropod prey of imported fire ants (Hymenoptera: Formicidae) in Mississippi sweetpotato fields
Authors: Rashid Tahir , Chen Jian , Vogt James T. , McLeod Paul J. 
Published: November 2012

AbstractThe red imported fire ants, Solenopsis invicta (Buren), are generally considered pests. They have also been viewed as beneficial predators feeding on other insect pests of various agroecosystems. This study documents the foraging habits of fire ants in a sweetpotato field in Mississippi. Fire ant foraging trails connecting outside colonies to a sweetpotato field were exposed and foraging ants moving out of the field toward the direction of the colony were collected along with the solid food particles they were carrying. The food material was classified as arthropod or plant in origin. The arthropod particles were identified to orders. Fire ant foragers carried more arthropods than plant material. Coleoptera and Homoptera were the most abundant groups preyed upon. These insect orders contain various economically important pests of sweetpotato. Other major hexapod groups included the orders Hemiptera, Diptera and Collembola. The quantity of foraged material varied over the season. No damage to sweetpotato roots could be attributed to fire ant feeding. Imported fire ant foraging may reduce the number of insect pests in sweetpotato fields.

BackgroundAcamprosate has been found to enhance rates of complete abstinence and to increase percent days abstinent (PDA) from alcohol relative to placebo treatment. As most U.S. clinical trials of acamprosate have been conducted in alcohol and other drug specialty clinics, there is a need to examine the efficacy of acamprosate in generalist settings. This study tested the efficacy of acamprosate versus placebo on the primary study outcome of PDA in the treatment of alcohol‐dependent patients in a family medicine setting. Secondary study outcomes included percent heavy drinking days (%HDD) and gamma glutamyltransferase level (normal or high).MethodsA randomized, double‐blind, placebo‐controlled, parallel group design of acamprosate was conducted in 2 family medicine settings (North Carolina and Wisconsin). One hundred volunteers were recruited primarily by advertisement, and participants were assigned to 666 mg (2 pills) oral acamprosate 3 times daily (1,998 mg/d) or matching placebo over a 12‐week period. All participants concomitantly received 5 sessions of a brief behavioral intervention from a family/primary care physician.ResultsNo significant treatment effect of acamprosate was found on PDA or the secondary outcomes. Significant treatment goal by time interaction effects was found on PDA and %HDD. Participants who had an initial goal of abstinence versus a reduction in alcohol use improved on average over time in PDA and had less %HDD from baseline to the end of treatment.ConclusionsThis clinical trial did not find evidence of efficacy for acamprosate compared to placebo among alcohol‐dependent individuals recruited primarily by advertisement as studied in a primary care setting. Drinking outcomes significantly improved regardless of medication condition. A goal of abstinence was significantly associated with improved drinking outcomes, suggesting that alcohol‐dependent patients with such a goal may do particularly well with counseling in a family medicine setting.

Published: November 2012

BackgroundAlcohol consumption has multiple biochemical consequences. Only a few of these are useful as diagnostic markers, but many reflect potentially harmful or beneficial effects of alcohol. Average consumption of 2 to 4 drinks per day is associated with lower overall or cardiovascular mortality risk than either lower or higher intake. We have analyzed the dose–response relationships between reported alcohol consumption and 17 biomarkers, with emphasis on intake of up to 3 drinks per day.MethodsBiochemical tests were performed on serum from 8,396 study participants (3,750 men and 4,646 women, aged 51 ± 13 years, range 18 to 93) who had provided information on alcohol consumption in the week preceding blood collection.ResultsGamma glutamyl transferase, alanine aminotransferase, aspartate aminotransferase, carbohydrate‐deficient transferrin, urate, ferritin, and bilirubin showed little or no change with alcohol consumption below 2 to 3 drinks per day, but increased with higher intake. High‐density lipoprotein cholesterol and albumin showed increasing results, and insulin showed decreasing results, across the entire range of alcohol use. Biphasic responses, where subjects reporting 1 to 2 drinks per day had lower results than those reporting either more or less alcohol use, occurred for triglycerides, glucose, C‐reactive protein, alkaline phosphatase, and butyrylcholinesterase. Increasing alcohol use was associated with decreasing low‐density lipoprotein cholesterol (LDL‐C) in younger women, but higher LDL‐C in older men.ConclusionsSome markers show threshold relationships with alcohol, others show continuous ones, and a third group show biphasic or U‐shaped relationships. Overall, the biochemical sequelae of low‐to‐moderate alcohol use are consistent with the epidemiological evidence on morbidity and mortality.

Hemagglutinating virus of Japan‐envelope (HVJ‐E) is a drug delivery vector based on inactivated Sendai virus. Recently, antitumor activities were found for HVJ‐E itself and clinical trials of HVJ‐E for some malignant tumors are now ongoing. We investigated the in vitro and in vivo antitumor effects of HVJ‐E against neuroblastoma, which is one of the most common malignant solid tumors in childhood. The sensitivity of human neuroblastoma cell lines to HVJ‐E correlated with the expression level of gangliosides, Sialylparagloboside (SPG) and GD1a, receptors for HVJ. Among the cell lines, SK‐N‐SH was the most sensitive to HVJ‐E in vitro and total SPG and GD1a expression was the highest. Complete eradication of subcutaneous tumors derived from SK‐N‐SH cells was achieved by intratumoral injection of HVJ‐E in SCID mice and no recurrence was observed for more than 300 days after HVJ‐E inoculation. In contrast, NB1 cells expressed the lowest amount of GD1a and SPG and were resistant to HVJ‐E in vitro. The expression of GD1a increased by 13‐cis retinoic acid (13cRA), which is a therapeutic drug for high risk neuroblastoma, thus leading to an improved sensitivity to HVJ‐E in vitro. Only growth inhibition of the subcutaneous tumors derived from NB1 cells was achieved by HVJ‐E in the SCID mice, but the combination of 13cRA and HVJ‐E could achieve partial eradication of the xenograft and also lead to an improved prognosis. In conclusion, HVJ‐E is a promising therapeutic modality for neuroblastoma and 13cRA can be used as an adjuvant to HVJ‐E.
