Area deprivation, individual socioeconomic position and smoking among women in South Korea

Background The objective of this study was to examine how area deprivation and individual socioeconomic position affect smoking among women using national survey data. Methods Smoking and individual sociodemographic characteristics were gathered from the Third Korea National Health and Nutrition Examination Survey, 2005. The Carstairs index was derived for each area using the 2005 census data. The data were analysed using multilevel logistic regression models. Results After adjusting for age and marital status, low education and manual jobs were significantly associated with a higher likelihood of smoking. In addition, the effect of manual jobs on smoking was modified by area deprivation. When individual occupation and area deprivation were examined together, results indicated that women with manual occupation had much greater odds of smoking when they lived in the least-deprived areas (OR, 4.03; CI, 2.00 to 8.14) than did women with manual job who lived in the middle- or most-deprived areas (OR, 2.19; CI, 1.15 to 4.16), compared to the reference group (housewives in the middle- or most-deprived areas). Conclusion The results of the present study show that among Korean women, manual work is associated with smoking, and the association is strongest among those living in the least-deprived areas. This interaction between manual work and area deprivation resulted in a higher smoking prevalence among women in affluent urban areas.
Posture control of robot manipulators with fuzzy voice commands using a fuzzy coach–player system

This paper presents a method of controlling robot manipulators with fuzzy voice commands. Recently, there has been some research on controlling robots using information-rich fuzzy voice commands such as 'go little slowly' and learning from such commands. However, the scope of all those works was limited to basic fuzzy voice motion commands. In this paper, we introduce a method of controlling the posture of a manipulator using complex fuzzy voice commands. A complex fuzzy voice command is composed of a set of fuzzy voice joint commands. Complex fuzzy voice commands can be used for complicated maneuvering of a manipulator, while fuzzy voice joint commands affect only a single joint. Once joint commands are learned, any complex command can be learned as a combination of some or all of them, so that, using the learned complex commands, a human user can control the manipulator in a complicated manner with natural language commands. Learning of complex commands is discussed in the framework of fuzzy coach–player model. The proposed idea is demonstrated with a PA-10 redundant manipulator.
Visible Integral-field Replicable Unit Spectrograph (VIRUS) optical tolerance

The Visible Integral-field Replicable Unit Spectrograph (VIRUS) instrument is made up of 150+ individually compact and identical spectrographs, each fed by a fiber integral field unit. The instrument provides integral field spectroscopy from 350 nm to 550 nm of over 33,600 spatial elements per observation, each 1.8 arcsec2 on the sky, at R ~ 700. The instrument will be fed by a new wide-field corrector (WFC) of the Hobby-Eberly Telescope (HET†) with increased science field of view as large as 22 arcmin diameter and telescope aperture of 10 m. The construction of the large number of VIRUS units requires the individual spectrographs be interchangeable at sub-system level and a production line assembly process be utilized, while meeting the optical performance specification. These requirements pose a strong emphasis on careful analysis of the manufacturing and alignment tolerances of the unit spectrograph design. In this paper, we detail the tolerance analysis, and discuss its implication to the optical performance and production of the VIRUS instrument.
CFS prediction of winter persistent inversions in the Intermountain Region

A recent study by Gillies and others of persistent inversion events in the Intermountain West of the United States found a substantive linkage between the intraseasonal oscillation (ISO) and the development of persistent inversion events. Given that NCEP’s Climate Forecast System (CFS) has demonstrated skill in the prediction of the ISO as far out as 1 month, it was decided to examine the CFS forecast’s capability in the prediction of such winter persistent inversions. After initial analysis, a simple regression scheme is proposed that is coupled to the CFS output of geopotential height as a way to predict the occurrence of persistent inversion events for Salt Lake City, Utah. Analysis of the CFS hindcasts through the period 1981‐2008 indicates that the regression coupled with the CFS can predict persistent inversion events with lead times of up to 4 weeks. The adoption of this coupled regression‐CFS prediction may improve the forecasting of persistent inversion events in the Intermountain West, which is currently restricted to the more limited time span (;10 days) of medium-range weather forecast models.
Etching of AIGaN/GaN HEMT structures by Cl2-based ICP

AIGaN/GaN mesa etching using different plasma combinations of Cl<sub>2</sub>/Ar, Cl<sub>2</sub>/BCl<sub>3</sub> and Cl<sub>2</sub>/CF<sub>4</sub> by inductively coupled plasma was investigated. It was observed that the etch rate of Cl<sub>2</sub>/Ar increases linearly with the Ar content. In contrast to the Ar-based mixtures, C<sub>l2</sub>/BCl<sub>3</sub> and Cl<sub>2</sub>/CF<sub>4</sub> plasma combinations show a damage-free surface. Furthermore, the lowest isolation current values achieved in devices with reduced sheet resistance were achieved by using C<sub>l2</sub>/BCl<sub>3</sub> plasma.
Antioxidant activity, phenol and flavonoid contents of 13 citrus species peels and tissues.

Methanolic extracts of 13 commercially available citrus spp. , peels and tissues growing in Iran were investigated for their antioxidant activity by DPPH method. IC50 for antioxidant activity ranged from 0.6-3.8 mg ml(-1). Total phenolic content of the citrus spp. samples (based on folin Ciocalteu method) varied from 66.5 to 396.8 mg gallic acid equivalent/g of extract and flavonoids content (based on colorimetric AlCl3 method) varied from 0.3 to 31.1 mg quercetin equivalent/g of extract. There were no correlation between the total phenolic and/or flavonoids contents and antioxidant activity in tissues and/or peels.
Photoacoustic Microscopy and Computed Tomography : From Bench to Bedside Lihong

Photoacoustic imaging (PAI) of biological tissue has seen immense growth in the past decade, providing unprecedented spatial resolution and functional information at depths in the optical diffusive regime. PAI uniquely combines the advantages of optical excitation and those of acoustic detection. The hybrid imaging modality features high sensitivity to optical absorption and wide scalability of spatial resolution with the desired imaging depth. Here we first summarize the fundamental principles underpinning the technology, then highlight its practical implementation, and finally discuss recent advances toward clinical translation.
A Scalable and Accurate Online Feature Selection for Big Data *

Feature selection is important in many big data applications. Two critical challenges closely associate with big data. Firstly, in many big data applications, the dimensionality is extremely high, in millions, and keeps growing. Secondly, big data applications call for highly scalable feature selection algorithms in an online manner such that each feature can be processed in a sequential scan. We present SAOLA, a Scalable and Accurate OnLine Approach for feature selection in this paper. With a theoretical analysis on bounds of the pairwise correlations between features, SAOLA employs novel pairwise comparison techniques and maintain a parsimonious model over time in an online manner. Furthermore, to deal with upcoming features that arrive by groups, we extend the SAOLA algorithm, and then propose a new group-SAOLA algorithm for online group feature selection. The group-SAOLA algorithm can online maintain a set of feature groups that is sparse at the levels of both groups and individual features simultaneously. An empirical study using a series of benchmark real data sets shows that our two algorithms, SAOLA and group-SAOLA, are scalable on data sets of extremely high dimensionality, and have superior performance over the state-of-the-art feature selection methods.
An Extension of A-A-K Hankel Approximation Theory Using State-Space Formulation

The optimal Hankel-norm approximation problem studied in [1] is reformulated in a state-space setting. It is shown that the A-A-K Hankel approximation theory can be generalized to optimal multivariable case. The optimal Hankel approximants obtained in this way are identical to those obtained by Glover [2], however, the present approach provides a deep insight into the A-A-K approximation theory and throws a new lignt on its future applications
An extended analytical study of Arabic sentiments

Due to the evolution of Web 2.0 technology, internet users are more capable of posting their comments and reviews to express their opinions and feelings about everything. Hence, the necessity of automatically identifying the polarity (be it positive, negative, or neutral) of these comments arose and new interdisciplinary field called sentiment analysis (SA) emerged. Unluckily, many studies were conducted on the English language whereas those on the Arabic language are quite few. In addition, the publicly available datasets and testing tools for SA of Arabic text are rare. In this paper, a relatively large dataset of Arabic comments is manually collected and annotated. The source is one of the most widely used social networks in the Arab world, Yahoo! -Maktoob. A comprehensive analysis of this dataset is presented and two popular classifiers, support vector machine (SVM) and Naive Bayes (NB) are used for empirical experimentations. The results show that SVM outperforms NB and achieves a 64% accuracy level.
A HFET millimeterwave resistive mixer

A millimeterwave resistive mixer based on a heterostructure field effect transistor (HFET) is described. A minimum conversion loss of 8 dB, including losses in the connectors, filters, substrates etc, is obtained in the frequency range 40-45 GHz. This is the highest frequency of operation reported for this type of mixer.
Analysis of influential factors for weathering of stone relics

Stone relics are our precious historical and cultural heritage. However, they are facing long-term weathering due to the particular environment where they exist, which brings us a lot of difficulty to protect cultural relics. In order to protect the cultural relics, right measures should be formulated according to the existing circumstances of cultural relics, pertinently analyzing their weathering. In this paper, the major influential factors of stone relic weathering have been analyzed based on the model of decision tree.
Preparation of herpes simplex virus of high titer

In nonpermissive DK cells abortively infected with the MPdkstrain of herpes simplex virus, viral deoxyribonucleic acid (DNA) and protein are produced only after infection with 3100 plaque-forming units (PFU) /cell (L. Aurelian and B. Roizman, J. Mol. Biol. 11:539, 1965). To study the nature and products of macromolecular synthesis in abortively infected cells, it was necessary to develop methods for the production of virus preparations of high potency. The objective of this paper is twofold: (i) to document several factors affecting virus yield, and (ii) to describe the procedure used for large-scale production of virus. Previous papers from this and other laboratories have shown that the optimal temperature for the multiplication of most virus strains is at or near 34 C. (A. E. Farnham and A. A. Newton, Virology 7:449, 1959; M. D. Hoggan and B. Roizman, Virology 8:508, 1959; K. 0. Smith, J. Bacteriol. 86:99, 1963). The exceptions are mutants specially selected for their ability to grow at high temperature [A. B. Germanov and M. I. Sokolov, Prob. Virol. (USSR) 12:182, 1967] and host range mutants such as the MPdk+sp virus selected for capacity to grow in DK cells at 37 C (B. Roizman, Virology 27:113, 1965). Incubation at 32 to 34 C is particularly advantageous, because at these temperatures infectious virus accumulates inside the cells and is not released efficiently into the extracellular fluid (M. D. Hoggan and B. Roizman, Virology 8:508, 1959). It has also been shown previously (B. Roizman, Proc. Soc. Exptl. Biol. Med. 119:1021, 1965) that the pH of the extracellular fluid affects virus yield. The optimal pH for the MPdkmutant is 6.8. The optimal pH for the MPdk+sp in both HEp-2 and DK cells is at or near 7.3. In recent studies on the nutritional and physiological requirements for maximal yields of MPdkvirus strain in HEp-2 cells and of MPdk+sp mutant in DK cells, it was found that maintenance media for infected cells consisting of mixture 199 with 1 to 5% calf serum are superior to media consisting of 1 to 10% calf serum, salts, amino acids, and vitamins once or twice the concentration recommended by H. Eagle (Science 130:432, 1959). The factor
Risk factors for fungal infection in patients with malignant hematologic disorders: implications for empirical therapy and prophylaxis.

To determine which patients are at high risk for disseminated fungal infection and should be given systemic prophylaxis, we studied the charts of 341 patients with malignant hematologic disorders who were admitted to our institution during 10 consecutive years. These patients represented 636 admissions; during these admissions, 60 invasive fungal infections occurred, with deaths in 44 cases. All patients who died of these infections either had persisting granulocytopenia and a poor prognosis for the underlying disease or suffered from chronic graft-vs.-host disease. Two of 58 patients who had no or low-level candidal colonization developed this infection (P < .001). Nine of the 10 patients with candidal infection had microbiologically proven bacteremia within the week preceding the candidal infection. After bone marrow transplantation, 8 of 10 patients with chronic graft-vs.-host disease vs. 2 of 36 without this disease (P < .001) developed fatal infection with Aspergillus species. The results of our study reveal that patients with high-level candidal colonization who were treated for microbiologically proven bacteremia and patients with chronic graft-vs.-host disease might benefit from systemic antifungal prophylaxis.
Cloning of two members of the SIRPα family of protein tyrosine phosphatase binding proteins in cattle that are expressed on monocytes and a subpopulation of dendritic cells and which mediate binding to CD4 T cells

Recent experimental studies have greatly clarified the function of cell surface molecules in the induction and modulation of T cell responses by antigen‐presenting cells (APC). However, the differences in ability to stimulate T cells evident for different types and subpopulations of the same APC, such as dendritic cell subsets, is less well understood. This report details an investigation of an antigen expressed on monocytes that is also expressed on a subset of cattle afferent lymph veiled cells (ALVC). A cDNA library derived from cattle monocytes was screened with monoclonal antibodies (mAb) for expression in COS‐7 cells. Using separate mAb for screening, two cDNA were cloned, the sequences of which showed a single long open reading frame encoding a predicted type I glycoprotein of 506 amino acids that contained three immunoglobulin superfamily domains and a long 112‐amino acid cytoplasmic tail. We have termed this antigen MyD‐1, reflecting its myeloid and dendritic cell distribution. Analysis of the EMBL database revealed that the molecule is a member of the recently described family of signal regulatory proteins (SIRP). The outeremost Ig domain was of the adhesion/receptor I‐type, suggesting that MyD‐1 might bind to a ligand on another cell. Evidence for this was subsequently obtained by demonstrating that COS‐7 cells transfected with MyD‐1 cDNA bound CD4 T cells and this binding was blocked by specific mAb. The potential importance of this interaction was supported by the finding that the proliferation of resting memory CD4 T cells to ovalbumin‐pulsed monocytes was significantly reduced in the presence of mAb to MyD‐1. A role for the molecule in the modulation of the monocyte/dendritic APC response is also predicted from the existence of multiple potential tyrosine phosphorylation sites in the cytoplasmic domain, including the presence of an immunoreceptor tyrosine‐based inhibitory motif (ITIM) and the observation that the SIRPα family members have been shown to bind to SHP‐1 and SHP‐2. Together these data indicate a possible functional importance for MyD‐1 in the regulation of monocyte and dendritic cell function.
Preparation and Application of Immobilized Surfactant-Modified PANi-CNT / TiO 2 under Visible-Light Irradiation

Hydrothermally and sol-gel-synthesized immobilized surfactant-modified polyaniline-carbon nanotubes/TiO2 (PANi-CNT/TiO2) photocatalysts were prepared and their application in the degradation of diethyl phthalate (DEP) under visible light at 410 nm was investigated in this sturdy. To improve the dispersion of nanoparticles and the transfer of electrons, the TiO2 surface was modified with both sodium dodecyl sulfate (SDS) and functionalized carbon nanotubes (CNT-COOH and CNT-COCl). With the addition of PANi, which was increased from 1%–5%, the adsorption edge of the prepared photocatalysts shifted to 442 nm. The SDS linked the PANi polymers to achieve a thickness of coating of the film of up to 314–400 nm and 1301–1600 nm for sol-gel hydrolysis and hydrothermally-synthesized photocatalysts, respectively. An appropriate film thickness would extend the transfer path of the electrons and inhibit the recombination of the electrons and the electron-holes. The photo-degradation performance of DEP by the hydrothermally-synthesized photocatalysts was better than those by sol-gel hydrolysis. The results revealed that the hydroxyl radicals were the key oxidant in the degradation of DEP using hydrothermally-synthesized PANi-CNT/TiO2 photocatalysts. The morphology and functional groups of the raw materials of photocatalysts were characterized and a comparison of photocatalytic activity with other TiO2-based photocatalysts was also provided.
Modelling Procedure and Development of Piezo Actuated Mechatronic Systems

The rapid growth in the last few years of high technologies such as micromanipulation, nanotechnology, scanning tunnelling and atomic force microscopy, etc. [5, 6, 8, 12, 16, 17, 18] has lead to the need of fast and appropriate modelling of components and systems for these technologies. Such systems are mostly piezo actuated and we shall further call them Piezo Actuated Mechatronic Systems (PAMS). This paper deals with the user friendly modelling procedure development and techniques for PAMS. Because of the complexity of the problem an interactive approach for the development of modelling procedure is introduced [2, 3, 4]. It is based on expert model oriented solutions in order to help the development process. As a more detailed description the following steps are considered:
Global Analysis of O-GlcNAc Glycoproteins in Activated Human T Cells

T cell activation in response to Ag is largely regulated by protein posttranslational modifications. Although phosphorylation has been extensively characterized in T cells, much less is known about the glycosylation of serine/threonine residues by O-linked N-acetylglucosamine (O-GlcNAc). Given that O-GlcNAc appears to regulate cell signaling pathways and protein activity similarly to phosphorylation, we performed a comprehensive analysis of O-GlcNAc during T cell activation to address the functional importance of this modification and to identify the modified proteins. Activation of T cells through the TCR resulted in a global elevation of O-GlcNAc levels and in the absence of O-GlcNAc, IL-2 production and proliferation were compromised. T cell activation also led to changes in the relative expression of O-GlcNAc transferase (OGT) isoforms and accumulation of OGT at the immunological synapse of murine T cells. Using a glycoproteomics approach, we identified >200 O-GlcNAc proteins in human T cells. Many of the identified proteins had a functional relationship to RNA metabolism, and consistent with a connection between O-GlcNAc and RNA, inhibition of OGT impaired nascent RNA synthesis upon T cell activation. Overall, our studies provide a global analysis of O-GlcNAc dynamics during T cell activation and the first characterization, to our knowledge, of the O-GlcNAc glycoproteome in human T cells.
Activity monitoring of workers using single wearable inertial sensor

This Activity monitoring of workers in installations such as industries, underground tunnels, sewerage lines, remote field deployments etc. is a daunting task. Due to lack of communication systems and scarce energy resources, these scenarios pose great challenges in developing a monitoring system for workers. The design of activity recognition system for workers, using a single tri-axial accelerometer is presented in this paper. Time, frequency and spatial domain features were extracted using a naturalistic dataset and were used to analyze the performance of various classifiers. FFT energy, entropy and correlation between axes showed good results in classification of 9 different activities. The various classification algorithms were tested using Weka classification tool and we have achieved up to 93.9% successful classification results using Random Forest algorithm.
Plasma Membrane Ca2+-ATPase Overexpression Depletes Both Mitochondrial and Endoplasmic Reticulum Ca2+ Stores and Triggers Apoptosis in Insulin-secreting BRIN-BD11 Cells*

Ca2+ may trigger apoptosis in β-cells. Hence, the control of intracellular Ca2+ may represent a potential approach to prevent β-cell apoptosis in diabetes. Our objective was to investigate the effect and mechanism of action of plasma membrane Ca2+-ATPase (PMCA) overexpression on Ca2+-regulated apoptosis in clonal β-cells. Clonal β-cells (BRIN-BD11) were examined for the effect of PMCA overexpression on cytosolic and mitochondrial [Ca2+] using a combination of aequorins with different Ca2+ affinities and on the ER and mitochondrial pathways of apoptosis. β-cell stimulation generated microdomains of high [Ca2+] in the cytosol and subcellular heterogeneities in [Ca2+] among mitochondria. Overexpression of PMCA decreased [Ca2+] in the cytosol, the ER, and the mitochondria and activated the IRE1α-XBP1s but inhibited the PRKR-like ER kinase-eIF2α and the ATF6-BiP pathways of the ER-unfolded protein response. Increased Bax/Bcl-2 expression ratio was observed in PMCA overexpressing β-cells. This was followed by Bax translocation to the mitochondria with subsequent cytochrome c release, opening of the permeability transition pore, and apoptosis. In conclusion, clonal β-cell stimulation generates microdomains of high [Ca2+] in the cytosol and subcellular heterogeneities in [Ca2+] among mitochondria. PMCA overexpression depletes intracellular [Ca2+] stores and, despite a decrease in mitochondrial [Ca2+], induces apoptosis through the mitochondrial pathway. These data open the way to new strategies to control cellular Ca2+ homeostasis that could decrease β-cell apoptosis in diabetes.
