Abstract
Background: There is a dearth of information on the compatibility of Western-developed, internet-based interventions that prevent onset and precipitation of depression in global settings. Recently, Project CATCH-IT (Competent Adulthood Transition with Cognitive-behavioral, Humanistic and Interpersonal Training), an information technology-based intervention, was adapted to prevent depression in Hong Kong Chinese adolescents. This paper evaluates qualitative data from consultations to develop a revised intervention of CATCH-IT for Hong Kong youth.
Methods: A theoretical thematic analysis approach was used to analyze data. Materials from three consultation trips which included focus groups (2007), an expert panel (2007), a public health campaign (2009), and a joint primary care physician-social worker review group (2010) were compiled. Authors (KS and AZ) independently reviewed the data and applied the theoretical framework of behavioral vaccines to code the data. These data were subsequently consolidated to provide a coherent narrative analysis.
Results: The cognitive behavioral therapy (CBT), behavioral activation (BA), and resiliency modules were maintained, while the interpersonal therapy (IPT) modules of CATCH-IT were excluded in the Hong Kong adaptation. Concurrent self-reports of drinking, smoking, illicit drug use and gambling behavior were added. Rather than primary care consultations, social worker consultations may be the best point of entry for intervention.
Conclusion: Socio-cultural relevance of psychotherapeutics and delivery context of internet-based interventions will require significant adaptation for the Hong Kong setting. However, because of community engagement throughout the process of adaptation, we believe the CATCH-IT intervention can be adapted for Chinese adolescents in Hong Kong with retained fidelity. The revised intervention is called “Grasp the Opportunity”.
Single Stage Single Switch Power Supply (S4PS)Design for Low Power HB-LED Lighting
Authors: Shrivastava Ashish , Singh Bhim 
Published: April 2013

Abstract
This paper presents an improved power quality converter (IPQC)-based power supply design for high brightness light emitting diode (HB-LED) low power lighting. The IPQC circuit uses a Cuk buck-boost converter to operate it in a discontinuous conduction mode (DCM) using the voltage follower technique for the mitigation of harmonic contents present in the AC mains current. Subsequently, reduction in harmonic contents results in improving the power quality indices at the AC mains. Single-stage single switch converter topology is used, which has less component count, size and cost as compared to the two-stage converter topology. DCM operation has an advantage that only output voltage control loop is required as compared to three control loops required in the continuous conduction mode operation. An 18-W LED driver is designed, modeled and simulated using MATLAB/Simulink software for 220 V, 50 Hz AC mains. The performance of the proposed LED driver is observed in terms of total harmonic distortion of the input current (THDi), input power factor (PF) and crest factor (CF) taking into account the strict international standard of IEC 61000-3-2 for class C equipments.

Published: April 2013

Abstract
This paper discusses experiences in the use of synchronized phasor measurement technology in Electric Reliability Council of Texas (ERCOT) interconnection, USA. Implementation of synchronized phasor measurement technology in the region is a collaborative effort involving ERCOT, ONCOR, AEP, SHARYLAND, EPG, CCET, and UT-Arlington. As several phasor measurement units (PMU) have been installed in ERCOT grid in recent years, phasor data with the resolution of 30 samples per second is being used to monitor power system status and record system events. Post-event analyses using recorded phasor data have successfully verified ERCOT dynamic stability simulation studies. Real time monitoring software “RTDMS”® enables ERCOT to analyze small signal stability conditions by monitoring the phase angles and oscillations. The recorded phasor data enables ERCOT to validate the existing dynamic models of conventional and/or wind generator.
Stabilizers and orbits of first level vectors in modules for the special linear groups
Authors: Osinovskaya Anna A. , Suprunenko Irina D. 
Published: April 2013

Abstract.Under some restrictions on the highest weight, the stabilizers of certain vectors in irreducible modules for the special linear groups with a rational action are determined. We consider infinitesimally irreducible modules whose highest weights have all coefficients at least 2 when expressed as a linear combination of the fundamental dominant weights and vectors whose nonzero weight components have weights that differ from the highest weight by a single simple root. For such vectors and modules a criterion for lying in the same orbit is obtained, and we prove that the stabilizers of vectors from different orbits are not conjugate. The orbit dimensions are also found. Furthermore, we show that these vectors do not lie in the orbit of a highest weight vector and their stabilizers are not conjugate to the stabilizer of such a vector.

Published: April 2013

Abstract
Rett syndrome is an X-linked dominant disorder frequently caused by the mutations in the methyl-CpG-binding protein 2 gene (MECP2). Its prevalence in the population is 1/15,000–20,000. Patients with Rett syndrome present apparently normal psychomotor developments during the first 6–18 months of life. Subsequently, they show a short period of developmental stagnation followed by a rapid regression in language and motor development. Precocious puberty is characterized by premature breast and pubic hair development, and advanced bone age development at 8 years of age. We present a case of Rett syndrome and precocious puberty in a 6-year-old girl. At the age of 6, the first signs of precocious puberty appeared (Tanner stage 3). Laboratory measurements were detected as follows: luteinizing hormone (LH), 0.2 mIU/mL; follicle-stimulating hormone (FSH), 1.1 mIU/mL; estradiol, 36 pg/mL; bone age, 9 years. The response to luteinizing hormone releasing hormone (gonadotropin-releasing hormone stimulation test) was characteristic for true precocious puberty (LH, 32 mIU/mL; FSH, 26 mIU/mL). This is the first reported case of precocious puberty related to Rett syndrome.

Authors: Ravelli Anita C.J. , Schaaf Jelle M. , Eskes Martine , Abu-Hanna Ameen , de Miranda Esteriek , Mol Ben Willem J. 
Published: April 2013

Abstract

Objective: To evaluate whether maternal ethnicity affects perinatal mortality by week of gestation from 39 weeks onwards.

Study design: In this cohort study, we used data from the nationwide Netherlands Perinatal Registry from 1999 until 2008. All singleton infants born between 39+0 and 42+6 weeks of gestation without congenital anomalies were included. We used crude and multivariate logistic regression analyses with white Europeans as the reference to calculate the adjusted odds ratios (aOR) of South Asian, African and Mediterranean women. The main outcome measure was perinatal mortality (antepartum and intrapartum/neonatal mortality within 7 days after birth).

Results: We studied 1,092,255 singleton deliveries. Perinatal mortality occurred in 2315 infants (2.1‰). There was interaction between gestational age and ethnicity (P<0.0001). In week 40 (40+0–40+6) South Asian (aOR 1.9; 95% CI 1.1–3.4) and Mediterranean (aOR 1.3; 95% CI 1.04–1.7) women had an increased risk of perinatal mortality. The perinatal mortality risk became greater in week 41 for South Asian (aOR 4.5 95% CI 2.8–7.2), African (aOR 2.2; 95%CI 1.4–3.4) and Mediterranean (aOR 2.2; 95% CI 1.8–2.9) women, especially among small for gestational age infants.

Conclusion: With increasing gestational age beyond 39 weeks, perinatal mortality risk increases more strongly among South Asian, African and Mediterranean women compared to European whites.
Are there gender related differences in neonatal abstinence syndrome following exposure to buprenorphine during pregnancy?
Authors: O’Connor Alane B. , O’Brien Liam , Alto William A. 
Published: April 2013

Abstract

Aim: To determine whether infant gender influences the course of neonatal abstinence syndrome (NAS) following exposure to buprenorphine during pregnancy.

Methods: A retrospective cohort study was performed in which maternal and infant data were collected for 46 male and 44 female infants. All infants were born to women enrolled in a buprenorphine treatment program from December 2007 until October 2012. Maternal and infant characteristics and outcomes were compared by infant gender.

Results: Male infants had a significantly higher mean peak NAS score (10.04 vs. 7.98, P=0.028) and were more likely to require pharmacologic treatment for NAS (39.1% vs. 11.4%, P=0.005).

Conclusions: These data indicate that, following exposure to buprenorphine during pregnancy, male infants experience a more severe withdrawal syndrome and are more likely to require pharmacologic treatment for NAS.

Published: April 2013

Abstract

Objective: To evaluate obstetric outcome after stillbirth according to placental and prothrombotic risk factors.

Methods: Obstetric outcomes of women with prior stillbirth and subsequent pregnancies were reviewed. Data on the immediate subsequent pregnancy included fetal loss, stillbirth, obstetric/medical complications, gestational age and birth weight at delivery, mode of delivery, thrombophilia, and prescribed medication. Placental stillbirth was defined as stillbirth associated with placental abruption, intrauterine growth restriction (IUGR), or histological evidence of placental infarcts. Controls were unselected women who gave birth at our center during a single calendar year. Factors influencing recurrence risks were estimated.

Results: Seventy-three subsequent pregnancies were identified. Five out of 73 (6.8%) women had a repeat stillbirth, significantly higher than controls (relative risk 22.2, 95% confidence interval 8.9–55.4). Four out of five repeat stillbirth cases occurred <37 weeks gestation. Hypertensive complications, diabetes and abruption were higher, while gestational age and birth weight at delivery were significantly lower than controls. Prior placental stillbirth was associated with a 10.5 times higher risk of IUGR in the subsequent pregnancy compared with non-placental stillbirth. All five repeat stillbirth cases occurred in thrombophilic women.

Conclusion: Women with prior stillbirth face an increased risk of pregnancy complications and stillbirth recurrence, especially with concurrent thrombophilia. Most repeat stillbirth cases occur preterm.

Abstract
We study the surface plasmon (SP) resonance energy of isolated spherical Ag nanoparticles dispersed on a silicon nitride substrate in the diameter range 3.5–26 nm with monochromated electron energy-loss spectroscopy. A significant blueshift of the SP resonance energy of 0.5 eV is measured when the particle size decreases from 26 down to 3.5 nm. We interpret the observed blueshift using three models for a metallic sphere embedded in homogeneous background material: a classical Drude model with a homogeneous electron density profile in the metal, a semiclassical model corrected for an inhomogeneous electron density associated with quantum confinement, and a semiclassical nonlocal hydrodynamic description of the electron density. We find that the latter two models provide a qualitative explanation for the observed blueshift, but the theoretical predictions show smaller blueshifts than observed experimentally.
The electronic structure and geometric structure of nanoclusters as catalytic active sites
Authors: Li Hao , Li Linsen , Li Yadong 
Published: April 2013

AbstractIn the past few decades, metal nanoparticles applied in heterogeneous catalysis have attracted extensive attention. The term nanocatalysis is broadly referred to as the unique catalytic effect of this series of materials. Although considerable progress has been made in nanocatalysis, it still remains a great challenge to fully understand the nature of active sites in the nanoscale. Many concepts and models have been put forwarded to describe the properties and performances of nano- and subnanoparticles in catalysis. In this review, we propose our perspective on the active sites of heterogeneous catalysis from the aspects of electronic structure and geometric structure of nanoclusters and consider briefly how these clusters function in catalysis. The challenge in nanocatalysis research methods is also discussed.
Mapping the Preservation Landscape for the Twenty-First Century
Authors: Harvey Ross , Mahard Martha 
Published: April 2013

AbstractInformation technology has had a profound effect on the preservation landscape at the beginning of the twenty-first century, blurring the traditional boundaries separating cultural heritage institutions and demanding new skills and approaches to the management of cultural assets, whether digital or analog. Concepts around which the core principles of preservation were built have been challenged and are shifting to accommodate new practices and standards. Changes in our approach to longevity, choice, quality, integrity, and access are being driven by digital technologies. A new set of principles, applicable to all materials, whether digital or not, are proposed. In the context and aims of preservation as we understand it today, these principles are a framework for the management of our cultural heritage collections.

Published: April 2013

Abstract:This paper reports on an effective ablation volume model for microwave ablation of porcine liver. Firstly, in order to obtain the temperature field distribution, a theoretical simulation model of the microwave ablation of porcine liver was developed by solving Pennes bioheat transfer equation using the COMSOL Multiphysics software. Then the effective ablation volume and the effective ablation volume model were obtained using the 1stOpt fitting software by 7D-Soft High Technology Inc. (China). Finally, microwave ablation experiments were carried out using porcine liver to verify the accuracy and effectiveness of the model. The results show that according to the ablation volume model, one can determine the scope of the effective ablation under varying conditions of microwave power and duration. This provides an important basis for the preoperative planning system of microwave ablation.
Application of high-resolution label-free imaging methods to obtain tissue images for histological analysis/Anwendung hochauflösender markierungsfreier Bildgebungsverfahren zur histologischen Analyse von Gewebebildern
Authors: Wu Yuxiang , Hu Wenyan , Fu Ling , Lv Xiaohua , Zeng Shaoqun 
Published: April 2013

AbstractIn routine clinical work, classical histology is regarded as the gold standard for the discrimination of healthy and pathological tissue. However, the whole process can be tediously long and has some restraints. As a result, under most conditions, doctors have to wait for the histological results until decisions can be made. In this paper, a practical procedure of tissue preprocess, serial section, label-free imaging and image analysis is demonstrated, which costs less time and could give sufficiently good contrast to obtain information about cellular structure and organization of biological tissues.
Compact AOTF-based spectral imaging system for medical endoscopic analysis
Authors: Machihin Alexander , Pozhar Vitold , Batshev Vladislav 
Published: April 2013

AbstractA prototype of a spectral imaging module is described which can be attached to conventional rigid and flexible medical endoscopes. It is based on acousto-optic tunable filters (AOTF) and provides fast spectral image registration at an arbitrary series of wavelengths. The main advantage of the device is the minimization of spatial and spectral image distortion by use of a specialized double AOTF monochromator. These properties ensure immediate and reliable detection of spectral features in any image pixel. Real-time spectral analysis, in addition to spectral visualization, provides the opportunity to make medical photoluminescence diagnostics more effective.
Novel proton exchange membranes with dimensional stability and permeability resistance based on sulfonate polynorbornenes
Authors: Xiao Shuqin , Zeng Rong , Chen Lie , Chen Yiwang 
Published: April 2013

Abstract
The novel proton exchange membranes of a direct methanol fuel cell (DMFC), the sulfonated functional polynorbornenes P(BN/NOH/NS), are successfully prepared via the sulfobutylation of poly(butoxymethylenenorbornene-co-norbornenemethanol) [P(BN/NOH)] with 1,4-butane sultone, and a cross-linked composite membrane consisting of P(BN/NOH/NS), P(BN/NOH), 4,5-imidazole dicarboxylic acid (IDA), and H3PO4 has also been developed. Adding the IDA/H3PO4 to the membrane promotes the proton conductivity of the cross-linked composite membrane to 2.79×10-3 S/cm at 80°C, which is six times higher than the P(BN/NOH/NS) membrane. At the same time, the rigid polynorbornene backbones remarkably improved the methanol permeability resistance and dimensional stability of P(BN/NOH/NS) and its cross-linked membrane, compared with the Nafion 115 membrane. A single cell based on the cross-linked composite membrane showed an open-circuit voltage of 0.483 V and power density of 1.35 mW/cm2.

Published: April 2013

Abstract
Starch plasticized with glycerol and blended with polyvinyl alcohol (PVA) is recommended for use as a biodegradable material. The present article reports the results of studies of the natural weather ageing of starch/PVA blends having various amounts of glycerol in natural weather conditions of Saudi Arabia, with special reference to morphology and thermal behavior. Neat PVA has been used as a control to understand its behavior in its blend with starch. Differential scanning calorimeter studies indicated that an increase in the exposure time of samples to natural environment increases the crystallinity of PVA due to the breakage of intermolecular hydrogen bonding, thus facilitating the removal of the amorphous portion of the polymers in the blend. Thermogravimetric analysis revealed that an increase in glycerol content enhanced the degradation of the polymer, which is corroborated with the findings from the surface morphology using scanning electron microscopy and Fourier transfer infrared spectroscopy analyses.
Die deutsche Religionswissenschaft im transnationalen Fachdiskurs

Published: April 2013

Zusammenfassung
In diesem Beitrag, der als Eröffnungsvortrag der Jahrestagung der Deutschen Vereinigung
für Religionswissenschaft in Heidelberg (2011) präsentiert wurde, geht es um die
internationale Präsenz der gegenwärtigen deutschen Religionswissenschaft. Es werden
vier Thesen vorgestellt und diskutiert: Dass die Religionswissenschaft eine transnationale Disziplin
sei; dass sich die deutsche Religionswissenschaft in ihrer Forschung zunehmend auf Europa
fokussiere, insbesondere auf das der Gegenwart; dass ihre Beteiligung am transnationalen Fachdiskurs
gering und weiter rückläufig sei; und dass ein Zusammenhang zwischen den letzten
beiden Punkten bestehe. Der Beitrag schließt mit dem Aufruf an die deutsche
Religionswissenschaft, sich thematisch breiter aufzustellen und international stärker
einzubringen.
A Common Enemy
Authors: Heß Cordelia 
Published: April 2013

Zusammenfassung
Die Benutzung des Begriffs Antiklerikalismus für eine Vielzahl von Phänomenen ohne eigentliche strukturelle Gemeinsamkeiten wird von der deutschsprachigen Mediävistik weitgehend abgelehnt, während im englischsprachigen Raum Geschichts- und Literaturwissenschaftler damit gerne die Kontinuitäten vom Spätmittelalter zur Reformation bezeichnen. Der vorliegende Artikel versucht, den für eine Binnendifferenzierung von kleruskritischen Bewegungen, Texten und Gruppen zugegebenermaßen ungeeigneten Begriff statt dessen für eine Kontextualisierung derselben nutzbar zu machen, indem er Gemeinsamkeiten zwischen kleruskritischen und orthodoxen Ideologien ausmacht: Antijudaismus und Antifeminismus. Dabei werden sowohl die Bruchstellen zwischen katholischer Kirche und antiklerikalen Bewegungen relativiert als auch die Bedeutung, die Antiklerikalismus als Indikator für die Epochengrenze zwischen Mittelalter und Früher Neuzeit beigemessen wird.
Structure of the Al2Cu(001) and Al9Co2(001) surfaces: role of the covalent-like bonding network and off-stoichiometric effects

Published: April 2013

ABSTRACTThe Al2Cu and Al9Co2 intermetallic compounds share structural similarities: they are bothdescribed in terms of coordination polyedra with a tetragonal symmetry and covalent-like bonding occur in both compounds. In this paper, the (001) surface structure of Al2Cu and Al9Co2 is described based on a combined scanning tunneling microscopy (STM), low-energy electron diffraction (LEED), X-ray and ultraviolet photoemission spectroscopy (XPS and UPS) and density functional theory (DFT) study. Surface models are elaborated from stoichiometric ideal compounds, leading to a pure aluminium plane as the surface termination in both cases. The nature of the constitutional defect in Al9Co2 is determined using density functional theory calculations. The influence of the surface atomic density, of the surface composition and of off-stoichiometric effects on the (001) surface structures of Al2Cu and Al9Co2 are discussed.
