Convergence theorems for modified generalized f-projections and generalized nonexpansive mappings
Authors: Cheng Qingqing , Su Yongfu , Zhang Jingling 
Published: August 2014

Abstract
The purpose of this paper is to study a sequence of modified generalized f-projections in a reflexive, smooth, and strictly convex Banach space and show that Mosco convergence of their ranges implies their pointwise convergence to the generalized f-projection onto the limit set. Furthermore, we prove a strong convergence theorem for a countable family of α-nonexpansive mappings in a uniformly convex and smooth Banach space using the properties of a modified generalized f-projection operator. Our main results generalize the results of Ziming Wang, Yongfu Su, and Jinlong Kang and enrich the research contents of α-nonexpansive mappings.

Letrozole vs Anastrozole for Height Augmentation in Short Pubertal Males: First Year Data
Authors: Neely E. Kirk , Kumar Rajiv B. , Payne Sydney L. , Ranadive Sayali A. , Suchet Diane I. 
Published: August 2014

Context:
Aromatase inhibitors are used off-label to treat short stature in peripubertal boys.

Objective:
To investigate short- and long-term hormonal and auxologic differences in short pubertal boys treated with letrozole (L) or anastrozole (A).

Design:
Patients are seen for laboratory evaluation and physical examination every 6 months, bone age yearly, DEXA and spine film every 2 years. They will be followed until they reach their final height. This is a preliminary report after 1 year of treatment.

Setting:
A single academic children's hospital outpatient clinic.

Patients:
Boys with age &gt;10 years, bone age ≤14 years, clinical and hormonal evidence of central puberty, and either height &lt; fifth percentile or predicted adult height (PAH) more than 10 cm below mid-parental height (MPH).

Intervention:
Letrozole (2.5 mg) or anastrozole (1 mg) was administered orally each day.

Main Outcome Measures:
Hormonal and clinical parameters, growth velocity, and change in bone age and PAH.

Results:
Thirty-nine boys have completed 1 year of treatment. Baseline means were age 14.1 years, PAH 166 cm, and testosterone 198 ng/dL. At 1 year, letrozole resulted in higher LH (L 6.1 ± 2.5 vs A 3.2 ± 1.7 IU/L) and testosterone (1038 ± 348 vs 536 ± 216 ng/dL) with lower estradiol (2.8 ± 2.8 vs 5.6 ± 2.9 pg/mL) and IGF-1 (237 ± 51 vs 331 ± 79 ng/mL). First year growth velocities were identical (7.2 cm/year), but an increase in PAH was greater in the anastrozole group (4.2 ± 3.5 vs 1.4 ± 4.4 cm, p = 0.03) after 1 year.

Conclusions:
We present first-year data from a direct comparison of anastrozole and letrozole for height augmentation in short pubertal boys. Letrozole was more potent in hormonal manipulation than anastrozole. First-year growth velocities were comparable, but improvement in PAH was greater in the anastrozole group. It remains to be seen if positive PAH trends will translate to increase in final height in either group.
Allosteric Regulation of the Ligand-Binding Ability of Zinc Porphyrins with Sterically Bulky Shielding Units by Metal Complexation
Authors: Ninomiya Yoshikazu , Kozaki Masatoshi , Suzuki Shuichi , Okada Keiji 
Published: August 2014

Abstract
An artificial allosteric system composed of a zinc porphyrin moiety as a ligand-binding site, diphenylanthracene moieties as sterically bulky shielding units, and bipyridine terminals as Fe(II) ion-binding sites, was designed, synthesized, and characterized. The allosteric system forms an [Fe(bpy)3]-type complex in the presence of Fe(II) ions and induces a large conformational change in the alkyl side chains and shielding units, in which the anthracene groups would cover both the top and bottom of the porphyrin Zn(II) center. Consequently, the ligand-binding ability of the zinc porphyrin unit was allosterically suppressed. We found that the formation of the Fe(II) complex resulted in a 9.5-fold reduction in the binding constant between the zinc porphyrin and 3,5-bis(3,5-di-tert-butylphenyl)pyridine at 20 °C. Comparisons of entropy and enthalpy changes in the absence and presence of Fe(II) ions led to the conclusion that the allosteric suppression was mainly due to the destabilization of the Zn(II)-coordinated complex owing to the steric repulsion between the ligand and the shielding unit.

. The

-norms we use are the so-called generalized Bargmann–Fock norms, and thus there are restrictions on the singularities of W as well as the density of W. Our sufficient conditions are that W has density less than 1 and is uniformly flat in a sense that extends to singular varieties the notion of uniform flatness introduced in [5]. We present an example of Ohsawa showing that uniform flatness is not necessary for extension in the singular case, and find an example showing that, for rather different reasons, uniform flatness is also not necessary in the smooth case. The latter answers in the negative a question posed in [5].

Zum Status von Intertextualität im Mittelalter: Tristan, Lancelot, Francesca da Rimini
Authors: Klinkert Thomas 
Published: August 2014

Riassunto
Il termine di intertestualità fu creato da Julia Kristeva e significa, tra l.altro, disseminazione e perdita del senso. Di conseguenza, nella critica letteraria, il concetto dell.intertestualità sensu Kristeva è stato applicato soprattutto nell.analisi di testi moderni, mentre alcuni critici addirittura ne negano la rilevanza per la letteratura medievale. Questo saggio cerca invece di dimostrare tramite l.analisi di tre testi (Il romanzo di Tristano, Le Chevalier de la Charrette, Inferno V) come, già nel Medioevo, dei rapporti intertestuali potessero provocare un effetto di disseminazione. La struttura dei testi letterari può dunque mostrarsi in contraddizione con i presupposti epistemologici di un.epoca che credeva nell.incarnazione del verbo e dunque nella verità assoluta e nel senso garantito da Dio.
Beatrice und die anderen Engel: die Musik (in) der Vita Nova
Authors: Kuhn Barbara 
Published: August 2014

Riassunto
Partendo dal fatto paradossale che la Vita Nova possa essere definito un »Buch der Lieder« (Wehle) o »libro dei canti«, pur parlando della musica in senso stretto solo in due luoghi, il presente contributo intende esaminare il rapporto esistente fra il libro e la »musica» in un senso più ampio e proporre una lettura della Vita Nova che mette l’accento proprio sulla musicalità delle poesie dantesche e le sue implicazioni. Le poesie stesse, come Beatrice, »angiola giovanissima«, e come Amore, agiscono come angeli: sono caratterizzate anche loro da cortesia e gentilezza e soprattutto trasmettono dolcezza e beatitudine, confermando così la convinzione medievale secondo cui il linguaggio degli angeli non sarebbe altro che musica, mentre da parte sua la musica - in primo luogo, s’intende, quella liturgica - riuscirebbe a comunicare già sulla terra un’idea del canto degli angeli. Qui, non solo la canzone è ›angelo‹ nel senso etimologico del termine, essendo mandata dall’io a portare un messaggio ai destinatari; non solo porta metaforicamente l’io, la cui lingua parla »quasi come per se stessa mossa«, al cielo. Innanzitutto, come fa vedere la rilettura di alcune ›canzoni‹, il linguaggio poetico riesce a dire l’ineffabile grazie alle sue caratteristiche proprie, che lo distinguono dal linguaggio tanto prosastico quanto prosaico, caratteristiche che ne fanno una specie di linguaggio angelico: è la poesia che con la sua suavitas riesce a superare i limiti del linguaggio umano e a procurare la beatitudine, trasportando coloro che la sanno udire già in vita »oltre la spera«.

Potential of Coplanar X-band GaN-MMIC Power Amplifiers
Authors: Ersoy Erhan , Chevtchenko Serguei , Kurpas Paul , Heinrich Wolfgang 
Published: August 2014

AbstractWhile the vast majority of GaN X-band PAs is realized as microstrip circuits, this paper reports design, fabrication and measurement of a coplanar version. The amplifier is processed using the FBH 4-inch GaN-on-SiC technology with 0.25 µm-gate GaN HEMTs. The two-stage power amplifier circuit delivers more than 12 W cw output power at 10 GHz, with a large-signal gain of 20 dB and a final stage drain efficiency of 45%. Benchmarking shows that these are best-in-class values for a coplanar X-band MMIC, which come very close to the state-of-the-art microstrip counterparts.

Published: August 2014

Abstract

Objective: The purpose of our study was to estimate the incidence and maternal and fetal outcomes of Hodgkin’s lymphoma (HL) in pregnancy.

Methods: We carried out a population-based cohort study on all births identified in the Healthcare Cost and Utilization Project-Nationwide Inpatient Sample from 2003 to 2011. We calculated disease incidence and used logistic regression analysis to estimate the adjusted effect of HL on maternal and neonatal outcomes.

Results: There were 638 cases of HL in pregnancy among 7,916,388 births, for an overall incidence of 8.06 per 100,000 births, with no perceivable trend over the 8-year study period. Relative to controls, HL in pregnancy was more common among Caucasians and women aged 25–34 years. After adjusting for baseline characteristics, women with HL in pregnancy were more likely to have preterm births, odds ratio (OR) 1.93 (1.53, 2.42) require postpartum blood transfusion, OR 1.38 (1.05, 1.82), and have venous thromboembolism (VTE), OR 7.93 (2.97, 21.22).

Conclusion: The incidence of HL in pregnancy appears to be higher than previously reported with no temporal trend over an 8-year period. Although there is a greater risk of preterm birth and maternal postpartum blood transfusion and VTE, overall maternal and neonatal major morbidity and mortality does not appear to be increased.
Analysis of shrinkage and creep behaviors in polymer-coated lightweight concretes
Authors: Bideci Alper , Bideci Özlem Sallı , Oymael Sabit , Yıldırım Hasan 
Published: August 2014

AbstractThe creep and shrinkage properties of polymer-coated lightweight concretes were examined. Five-hundred-dose lightweight concretes were produced by coating pumice aggregates with three different polymers (Sonomeric1: SNMC, KB Pur 214: KBP, and Polipol3455: PLP). The 3-, 7-, and 28-day compressive strength values of the obtained lightweight concrete samples were determined, and the 840-h and 12-month creep and shrinkage deformations were measured. It was found that the ductility of the SNMC- and KBP-coated concrete samples increased, while their shrinkage deformation results decreased when compared with the control samples. In contrast, the ductility of PLP concrete samples decreased and the shrinkage deformation became higher. In conclusion, the use of SNMC- and KBP-coated pumice aggregates had a positive effect on the creep and shrinkage properties of the concrete. Furthermore, it was observed that the compressive strength values of the lightweight concretes made of the coated samples were higher than those of the control sample.
Vaccine Message Framing and Parents’ Intent to Immunize Their Infants for MMR
Authors: Hendrix Kristin S. , Finnell S. Maria E. , Zimet Gregory D. , Sturm Lynne A. , Lane Kathleen A. , Downs Stephen M. 
Published: August 2014

BACKGROUND AND OBJECTIVE:
Emphasizing societal benefits of vaccines has been linked to increased vaccination intentions in adults. It is unclear if this pattern holds for parents deciding whether to vaccinate their children. The objective was to determine whether emphasizing the benefits of measles-mumps-rubella (MMR) vaccination directly to the vaccine recipient or to society differentially impacts parents' vaccine intentions for their infants.

METHODS:
In a national online survey, parents (N = 802) of infants &lt;12 months old were randomly assigned to receive 1 of 4 MMR vaccine messages: (1) the Centers for Disease Control and Prevention Vaccine Information Statement (VIS), (2) VIS and information emphasizing the MMR vaccine's benefits to the child, (3) VIS and information emphasizing societal benefits, or (4) VIS and information emphasizing benefits both to the child and society. Parents reported their likelihood of vaccinating their infants for MMR on a response scale of 0 (extremely unlikely) to 100 (extremely likely).

RESULTS:
Compared with the VIS-only group (mean intention = 86.3), parents reported increased vaccine intentions for their infants when receiving additional information emphasizing the MMR vaccine’s benefits either directly to the child (mean intention = 91.6, P = .01) or to both the child and society (mean intention = 90.8, P = .03). Emphasizing the MMR vaccine’s benefits only to society did not increase intentions (mean intention = 86.4, P = .97).

CONCLUSIONS:
We did not see increases in parents’ MMR vaccine intentions for their infants when societal benefits were emphasized without mention of benefits directly to the child. This finding suggests that providers should emphasize benefits directly to the child. Mentioning societal benefits seems to neither add value to, nor interfere with, information highlighting benefits directly to the child.
Health Care Provider Advice for Adolescent Tobacco Use: Results From the 2011 National Youth Tobacco Survey
Authors: Schauer Gillian L. , Agaku Israel T. , King Brian A. , Malarcher Ann M. 
Published: August 2014

BACKGROUND:
Health care providers play an important role in promoting tobacco use abstinence among adolescents. This study aimed to provide nationally representative data on the prevalence of provider tobacco use screening and advice delivered to adolescents. Cessation behaviors and correlates of past year quit attempts among current smokers are also explored.

METHODS:
Data came from the 2011 National Youth Tobacco Survey, a nationally representative school-based survey of adolescents in grades 6 through 12 (n = 18 385). Provider screening and advice were assessed by smoking status and demographic characteristics. Logistic regression was used to assess the association between advice and past year quit attempt.

RESULTS:
The overall prevalence of current tobacco use was 16.6%; 10.8% were current cigarette smokers (3.6% were established smokers, 7.2% were nonestablished smokers); 17.3% were former smokers; and 71.9% were never smokers (22.6% high susceptibility, 77.4% low susceptibility). Among all respondents, the prevalence of being asked about tobacco use by a health care provider was 32.2%; the prevalence of being advised to quit or avoid tobacco was 31.4%. Established smokers were more likely than other groups to report provider assessment of tobacco use and advice. Receipt of advice was associated with a higher adjusted odds of having made a past year quit attempt (odds ratio: 1.47, 95% confidence interval: 1.18–1.82).

CONCLUSIONS:
Less than one-third of adolescents report being asked about tobacco use or being advised not to use tobacco. Increased tobacco use intervention by health care providers is needed to prevent initiation and increase cessation.

ABSTRACTWe studied the effect of a cross-conjugated bridging group (χC) on charge-transfer in a push-pull chromophore system. The hyperpolarizability of such molecules was found to be comparable to that of a fully π-conjugated molecule (πC) with the same donor and acceptor. The cross-conjugated moiety was then applied as a pendant to a fully π-conjugated chromophore containing a tricyanopyrroline acceptor (TCP). The addition of a χC moiety did not alter the intrinsic hyperpolarizability and provides an avenue for extending and aiding πC systems. The molecules were examined by X-ray diffraction (XRD), hyper-Raleigh scattering (HRS) and UV-visible (UV-vis) spectroscopy. Experimental results were compared with the predictions of density functional theory (DFT). Cross-conjugated molecules have comparable β values, relative to πC molecules, due to reduced spatial overlap between the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO). Thus, the χC architecture could facilitate independent modification of donor and acceptor strengths while minimizing unfavorable effects on electronic transitions and dipole moments.

Published: August 2014

ABSTRACTA new donor-acceptor structured conjugated polymer (PDODTBI) with trifluoromethylated benzimidazole and benzo[1,2-b;3,4-b']dithiophene (BDT) unit have been designed and synthesized using Stille coupling polymerization reaction. The polymer is highly soluble in common organic solvents such as chloroform, tetrahydrofuran and chlorobenzene with good film forming properties. The structure of the polymer is elucidated by 1H NMR and FTIR spectroscopic techniques. The introduction of a trifluoromethyl group at 4th position of the benzimidazole unit has significantly altered the optical and electrochemical properties of polymer. Polymer film showed broad absorption band in the range of 400-680 nm. Optical band gap of the polymer estimated from the absorption band edge and is found to be ∼1.88 eV. Polymer exhibited deeper HOMO (-5.0 eV) and the LUMO (-3.12 eV) energy levels. Bulk heterojunction (BHJ) solar cell device with PDODTBI as a donor and PC61BM as an acceptor were evaluated.
Characterization of Green Synthesized Copper Nanoparticles Stabilized by Ocimum Leaf Extract

Published: August 2014

ABSTRACTCopper nanoparticles are synthesized successfully through chemical reduction of different copper salts stabilized by Ocimum Sanctum Leaf extract, a natural biopolymer. The resulting copper nanoparticles are characterized by using UV Visible Absorption Spectrometer, X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Small Angle X-ray Scattering (SAXS) and Fourier Transform Infrared Spectroscopy (FTIR) experiments. Copper nanoparticles prepared display an absorption peak at around 558 nm. X-ray diffraction analysis shows that the particles are FCC crystalline. SEM and TEM display the formation of copper nanoparticles with an average size of 10 nm. The SAXS studies demonstrate the formation of spherical nanoparticles with bimodal size distribution. The FTIR spectrum analysis has confirmed the presence of functional groups of stabilizer Ocimum Sanctum leaf extract in capping the copper nanoparticles.
