STAR FORMATION ACTIVITY IN THE LONG, FILAMENTARY INFRARED DARK CLOUD G53.2

We present star formation activity in the infrared dark cloud (IRDC) G53.2, a remarkable IRDC located at Galactic coordinates ( l , b ) ∼ ( 53 &fdg; 2 , 0 &fdg; 0 ) ? > based on the census of young stellar object (YSO) candidates. IRDC G53.2 was previously identified as several IRDCs in mid-IR images, but it is in fact a long ( ≳ 45 ? > pc) cloud, well consistent with a CO cloud at v ∼ 23 ? > km s−1 (or at d ∼ 1.7 ? > kpc). We present a point-source catalog of IRDC G53.2 that contains ∼370 sources from our photometry of the Spitzer MIPS 24 μm data and Galactic Legacy Infrared Mid-Plane Survey Extraordinaire Catalog. The classification of the identified sources based on their spectral index and control field analysis to remove field star contamination reveals that IRDC G53.2 is an active star-forming region with ∼300 YSO candidates. We compare the YSO classification based on spectral index, mid-IR colors, and the wavelength range used, which results in consistent classification, except for flat-spectrum objects, with some ambiguity between Class I and II. Comparison of the YSO population in IRDC G53.2 with those of other nearby star-forming clusters indicates that they are similar in age; on the other hand, stronger association with mid-IR stellar sources in IRDC G53.2 compared with other IRDCs indicates that IRDC G53.2 is at a later evolutionary stage among IRDCs. Spatial distribution of the YSO candidates in IRDC G53.2 shows a good correlation with 13CO column density and far-IR emission, and earlier-class objects tend to be more clustered in the regions with higher density.
The Solar Microwave Flux and the Sunspot Number

The solar F10.7 index is has been a reliable and sensitive activity index since 1947. As with other indices, it has been showing unusual behavior in the Cycle 23/24 minimum. The origins of the solar microwave flux lie in a variety of features, and in two main emission mechanisms: free-free and gyroresonance. In past solar cycles F10.7 has correlated well with the sunspot number SSN. We find that this correlation has broken down in Cycle~23, confirming this with Japanese fixed-frequency radiometric microwave data.
Overview of the Therapeutic Effects of Origanum vulgare and Hypericum perforatum Based on Iran's Ethnopharmacological Documents

Abstract Herbs have played an important role in the health and wellness of human beings. Nowadays, medicinal herbs are at the forefront of studies of medical science because of their importance in public health. Understanding the traditional and therapeutic effects of medicinal plants is important because they can be effective as a source of medication. Based on the results obtained from the review of Iran's ethnopharmacological literature, it was found that the Origanum vulgare can be used as energy producer, diuretic, stomach booster, nervous system reliever, laxative, anticancer, relief of migraine, fracture healing, numbness of organs, relief of toothache, disinfectant, anticonvulsant, expectorant, analgesic, antitussive, anti-inflammatory, menstrual regulator, decreases urinary tract infection, treatment of sexual dysfunction, colic, sinusitis, cardiac tonic and blockage remover. Also, Hypericum perforatum is used as a digestive and nervous system relaxant, respiratory and uterine stimulant, a booster of the immune system, antidepressant, anticancer, anti-AIDS, analgesic, bile cathartic, relaxing, anti-tussive, analgesic, treating nervous system diseases, astringent, antiparasitic, expectorant, diuretic, and blood pressure regulator. Preliminary results presented in this review study enlighten us that the herbal plants could be the basis for experimental and clinical studies to promote the use of natural agents in the treatment of human diseases.

The CHESS project has been working with Cite de l’espace, a space technology centre, to explore the use of tablets and mobile phones to deliver visitor experiences that integrate across multiple experiences. In this paper, we articulate three key challenges present at Cite, describe a prototype experience developed by CHESS, and present a set of observations developed through an evaluation conducted in October 2012.
Are We Better-off for Working Hard?

When traders are uncertain on being informed and make effort to reduce their uncertainty, we would expect an improvement in both the welfare and price efficiency. By considering the disutility of the effort, we characterize the non-cooperative information game on traders' decision of making effort through a Nash equilibrium and asset price through a noisy rational expectation equilibrium. We show that making effort to be informed is harmful for social welfare. Also improving market efficiency is always at the cost of welfare reduction. Therefore, with the disutility of making effort to reduce the uncertainty on being informed, social welfare can be improved when traders make less effort, and more importantly, social welfare and price efficiency cannot be improved simultaneously.
Critical questions on nutrition of preterm infants

Infants born preterm represent a nutritional emergency that must be addressed immediately in order to avoid/limit the development of nutritional deficits that lead to postnatal growth retardation. When taking care of preterm infants from a nutritional point of view, it must be taken into consideration that promotion of growth is achieved by the accomplishment of their high nutritional needs, that become even more demanding with the occurrence of comorbidities. Identification of the factors that determine and/or affect nutrient requirements is therefore mandatory. A full understanding of the most appropriate biological setting that should be used for establishing preterm infants nutritional requirements is desirable. A deeper knowledge with regard to these points would allow for the provision of appropriate amount of specific essential nutrients, avoiding the under- or overexposure to certain nutrients, and for the individualization of nutritional care of preterm infants. The avoidance of early malnutrition is of major importance since adequate postnatal growth has been associated with improvement of later neurodevelopment outcome. Limitation of extrauterine growth restriction prevents the need for rapid catch-up growth after discharge which, in turns, has been linked to later adverse metabolic consequences. Increasing evidence has indicated that postnatal growth retardation is accompanied by a fat-free mass deficit, probably related to immature metabolic mechanisms, delayed amino acid administration and protein intakes lower than recommendations. The potential long-lasting effects of these body composition modifications on future health, both in terms of neurodevelopment outcome and metabolic risk, are still under investigation.
MODULATED MEDIUM FOR GENERATION OF TRANSITION RADIATION

It is shown on an example of amorphous quartz, under the influence of a standing microwave field, at its certain parameters, superlattice is created in the medium where difference in values of dielectric constants of neighboring layers can be up to third order. This superlattice exists during the nanosecond, however it is sufficient for using it as a radiator for generation of transition radiation by relativistic electrons.
Linguistic, Cognitive and Cultural Dimensions of the Narrative Written Production of Arabic and Spanish Speakers

Ever since 1980s, much research has been done investigating the writing processes of L2 writers of different ages and abilities. Despite the abundance in such a research, there seems to be a dearth of studies on comparing the writing proficiency of both Arabic and Spanish speakers narrating in English. Motivated by such a huge research gap, this study was undertaken to answer the following questions: (1) what factors affect L2 learners accurate performance in writing, apart from their level of morphosyntactic competence? ; (2) from the cognitive perspective, do Arabic speakers differ from Spanish speakers during writing narrative texts? , and what is the nature of this difference (if it exists)? ; and (3) from the cultural perspective, do Arabic speakers differ from Spanish speakers in writing narrative texts? , and what is the nature of this difference (if it exists)? The subjects were ten foreign graduate students at the University of Pittsburgh, USA. They belonged to two different linguistic and cultural backgrounds. The first was from the Arabic language group, and the second was from the Spanish linguistic group. The data were taken from (1) a questionnaire; (2) writing a narrative text, and (3) individual interviews. The data were analyzed both qualitatively and quantitatively. The linguistic analysis of the data focused on the numbers of errors in the light of how many words that each subject produced in his/her essay, and the reason for these errors. In addition, both the cognitive and cultural aspects of the subjects’ written productions were examined and analyzed. Based on such analyses, recommendations were made.
Inhibition of human ceruloplasmin (ferroxidase) by cadmium

Ceruloplasmin (Cp) is a human plasma protein with multiple physiological functions including ferroxidase and oxidase activities. Deficiency or inhibition of the enzyme may lead to some abnormalities, including iron deposition in several tissues and causes various pathological conditions in the body. Direct interaction of cadmium (Cd), a widespread, highly toxic environmental pollutant, with human Cp leads to reversible inhibition of the enzyme. Therefore, investigation of kinetic parameters of Cp in the presence of Cd will lead to a better understanding of mechanism by which Cd inhibit Cp activity. In the present study, Cd inhibited Cp in vitro progressively up to a concentration of 2 mM where about 75% of the enzyme activity was lost 10 min after addition of Cd. An inhibitory constant (ki) of about 1.1 mM was calculated from the slope replot. Fluoroscopic study also was carried out on the native and Cd-inhibited enzyme. Maximum emission spectrum of the inhibited enzyme showed an increased level of about 62% with regard to the native enzyme. Cd-induced enzyme inhibition was prevented by sulfhydryl compounds such as glutathione (1.2, 12 mM), and β-mercaptoethanol (12 mM). The data suggest that a conformational change in the native enzyme due to Cd binding caused enzyme inactivation and sulfhydryl groups on the enzyme probably are involved in inhibition by Cd.
Thermodynamic and dynamic ice thickness contributions in the Canadian Arctic Archipelago in NEMO-LIM2 numerical simulations

Abstract. Sea ice thickness evolution within the Canadian Arctic Archipelago (CAA) is of great interest to science, as well as local communities and their economy. In this study, based on the NEMO numerical framework including the LIM2 sea ice module, simulations at both 1∕4 and 1 / 12 ∘ horizontal resolution were conducted from 2002 to 2016. The model captures well the general spatial distribution of ice thickness in the CAA region, with very thick sea ice ( ∼ 4 m and thicker) in the northern CAA, thick sea ice ( 2.5 to 3 m) in the west-central Parry Channel and M'Clintock Channel, and thin ( m) ice (in winter months) on the east side of CAA (e.g., eastern Parry Channel, Baffin Island coast) and in the channels in southern areas. Even though the configurations still have resolution limitations in resolving the exact observation sites, simulated ice thickness compares reasonably (seasonal cycle and amplitudes) with weekly Environment and Climate Change Canada (ECCC) New Ice Thickness Program data at first-year landfast ice sites except at the northern sites with high concentration of old ice. At 1∕4 to 1 / 12 ∘ scale, model resolution does not play a significant role in the sea ice simulation except to improve local dynamics because of better coastline representation. Sea ice growth is decomposed into thermodynamic and dynamic (including all non-thermodynamic processes in the model) contributions to study the ice thickness evolution. Relatively smaller thermodynamic contribution to ice growth between December and the following April is found in the thick and very thick ice regions, with larger contributions in the thin ice-covered region. No significant trend in winter maximum ice volume is found in the northern CAA and Baffin Bay while a decline ( r2 ≈ 0.6 , p ) is simulated in Parry Channel region. The two main contributors (thermodynamic growth and lateral transport) have high interannual variabilities which largely balance each other, so that maximum ice volume can vary interannually by ± 12 % in the northern CAA, ± 15 % in Parry Channel, and ± 9 % in Baffin Bay. Further quantitative evaluation is required.
The North African Mosasaur Globidens phosphaticus from the Maastrichtian of Angola

New mosasaur fossils from Maastrichtian beds at Bentiaba, Angola, representing elements of the skull and postcranial axial skeleton from two individuals of the durophagous genus Globidens, are reported. Based on dental morphology, specifically the inflated posterior surface and vertical sulci, the Bentiaba specimens are identified as Globidens phosphaticus, a species defined by characters of a composite dentition from the Maastrichtian of Morocco. Comparisons indicate that G. phosphaticus is most closely related to G. schurmanni, from the late Campanian of South Dakota, the youngest north American Globidens species at about 72.5 Ma. The morphology of the premaxilla and its relationship with the maxillae is unique among mosasaurs, and supports the taxonomic validity of G. phosphaticus. In contrast with earlier species of the genus, G. phosphaticus is currently known from north and west Africa, the Middle East and the central eastern margin of South America, suggesting it may have been restricted to the Maastrichtian tropical zone as previously hypothesised.
What Should Central Banks Target? Evidence on the Impact of Monetary Policy Regimes on Economic Growth

Economists and policy-makers have long sought the ideal framework for monetary policy as it is arguably one of the most important tools for government to influence the economy. Exchange rate and inflation are believed to be the most appealing anchors for providing guidance to the conduct of monetary policy and are thus widely used in the real world. Most existing studies on the effect of exchange-rate arrangements and inflation targeting on economic growth suffer from the absence of a clear counterfactual, rendering it difficult to interpret their results. Based on a new classification scheme on monetary policy regimes, this paper helps to fill that gap by investigating the effect of monetary policy regimes on growth. Our results consistently support that an inflation targeting regime has a positive impact on economic growth when compared with an exchange-rate targeting regime.
Neuromuscular fatigue following a singles badminton match

Methods Ten Australian state-level male badminton players volunteered to participate in this study. Both femoral nerve and muscle electrical stimulations were used in the present study. Maximal voluntary isometric contraction (MVC) torque of the knee extensors and flexors, voluntary activation during the knee extension MVC (VA), torque generated by a doublet (DT), 20 Hz (T20) and 80 Hz stimulation (T80) were measured pre, immediately (8 10 min after match), 1-hour and 24-hour post match. Lunges were obtained from video analysis from each match. Pearson product-moment correlations were computed to examine relationships between variables using ANOVA.
The STAR RNA Binding Proteins SAM68, SLM-1 and SLM-2 Interact with Kinesin-I

In neurons, kinesin is the molecular motor that transport cargos along microtubules. KIF5s (alias kinesin-I), are heterotetrameric motor conveying cargos, but the mechanism as to how they recognize and bind to a specific cargos has not yet been completely elucidated. To identify the interaction proteins for KIF5C, yeast two-hybrid screening was performed, and specific interaction with the Sam68-like mammalian protein 2 (SLM-2), a member of the signal transducers and activators of RNA (STAR) family of RNA processing proteins, was found. SLM-2 bound to the carboxyl (C)-terminal region of KIF5C and to other KIF5 members. The C-terminal domain of Sam68, SLM-1, SLM-2 was essential for interaction with KIF5C in the yeast two-hybrid assay. In addition, glutathione S-transferase (GST) pull-downs showed that SAM68, SLM-1, and SLM-2 specifically interacted to Kinesin-I complex. An antibody to SAM68 specifically co-immunoprecipitated SAM68 associated with KIF5s and coprecipitated with a specific set of mRNA. These results suggest that Kinesin-I motor protein transports RNA-associated protein complex in cells.
INVESTIGATIONS ON THE NUCLEATION PROCESSES IN FRUSTRATED POLYMERIC SYSTEMS

By means of Monte Carlo simulations, we investigated the nucleation of polymers in frustrated spaces, i.e. in spaces where one dimension is much smaller (or larger) than other (or others). The obtained results were compared with those predicted by the Avrami equation. In the case of the spontaneous nucleation, we found similarities with respect to the ordinary crystallization case, but the Avrami index has smaller values. For instantaneous nucleation conditions, we observed to have two distinctive regimes: 3dimensional crystallization at the beginning of the process, followed by a behavior which is similar with the one that occur in spaces with low dimensionalities.
Estimating Consumer Demand for Information Attributes Using Twitter Data

In 2006, a new social web service was launched: Twitter. That service was centered around the idea that each user could follow other users, but there was no requirement for reciprocation. This lack of reciprocation between creators of content, and those who consume the content, exhibits an advantages property for economists: you directly observe the demand curve (if a set of criteria
Design and analysis of 80-W wideband asymmetrical Doherty amplifier

This paper presents the analysis and design of a wideband asymmetrical Doherty amplifier. The frequency response of the output combining network of the Doherty amplifier with arbitrary back-off level configuration is analyzed. Other bandwidth-limiting factors were discussed and analyzed as well. A number of performance enhancement techniques were taken into consideration to obtain high and flat back-off efficiency over the amplifier design band of 1.7–2.25 GHz. The designed Doherty amplifier had, at 8.0–9.9 dB output back-off, a minimum efficiency of η = 50% [power-added efficiency of 45%], measured near 40 dBm of output power, and over 28% bandwidth. Using digital predistortion (DPD) linearization, an adjacent-channel leakage ratio (ACLR) of −43 dBc was obtained for a single-carrier W-CDMA signal, at 40.9 dBm and 46% of average output power and drain efficiency, respectively. The designed amplifier represents the first wideband Doherty amplifier reported over extended power back-off range.
High prevalence of immunoglobulin A deficiency in patients with type 1 diabetes mellitus detected by ELISA

RESUMO Objetivo: Medir as concentrações séricas de imunoglobulina A por ensaio imunoenzimático (ELISA) em pacientes com diabetes mellitus tipo 1 (DM-1) e verificar a prevalência da deficiência de imunoglobulina A (DIgA) em pacientes diabéticos. Métodos: A concentração sérica de imunoglobulina A foi determinada em 149 pacientes portadores de DM-1 por três métodos. A DIgA foi definida como sendo nível sérico inferior a 5 mg/dl. Quando os níveis séricos de imunoglobulina A eram indetectáveis por turbidimetria, realizou-se imunodifusão radial em concentração de placa baixa. Para os pacientes em que os níveis séricos de imunoglobulina A foram indetectáveis pelos dois métodos anteriores, a imunoglobulina sérica foi quantificada por ELISA. Em pacientes com DIgA, os níveis de imunoglobulina G e M foram medidos por turbidimetria para excluir outras deficiências humorais. Resultados: Dos 149 pacientes portadores de DM-1 avaliados, 141 (94,6%) tinham níveis séricos normais de imunoglobulina A por turbidimetria. Oito pacientes (5,3%) apresentavam níveis séricos indetectáveis de imunoglobulina A por turbidimetria e imunodifusão radial. Nesses oito pacientes, a determinação sérica de imunoglobulina A foi realizada por um método mais sensível, ELISA. Níveis séricos muito baixos de imunoglobulina A foram detectados nesses pacientes diabéticos. Em todos os pacientes diabéticos, os níveis séricos de imunoglobulinas G e M medidos por turbidimetria foram normais para a idade. Todos os 150 pacientes do Grupo Controle tiveram níveis séricos normais de imunoglobulina A por ELISA. Conclusões: Houve uma prevalência significativamente alta de DIgA entre os pacientes diabéticos tipo 1 (5,3%). A dosagem de imunoglobulina A em todos os pacientes diabéticos do tipo 1 é necessária, especialmente na fase anterior a alguns testes de triagem baseados em anticorpos de imunoglobulina A. Pacientes com DIgA podem ter resultados falsos-negativos para testes de triagem de doença celíaca envolvendo anticorpos antiendomisio e antigliadina.
UNIVERSITY-INDUSTRY PARTNERSHIPS FOR INNOVATION: SRI LANKAN EXPERIENCES

The University sector in the national innovation system (NIS) is considered as one of the key players which links new knowledge with the industry for the purpose of diffusing new knowledge for economic and social benefits through commercialization of products, services, processes and other artifacts. This paper inquires the role of Sri Lankan universities in the innovation process by paying special attention on the strength of university-industry linkages. Responses from the industrial sector obtained through a surveys and interviews with respondents. Data presented and analyzed through descriptive statistics using summery statistics and figures. Social Network Analysis (SNA) was employed to determine the strength of the networking relationship among the Universities and the Firms Qualitative data were analyzed employing the method of content analysis. The study revealed a positive trend in the higher education sector towards performing effective role in the future towards innovation. However, it was evident that these relationships are still remained very weak. The industrial sector remains inward oriented with little intention to innovation while universities still prioritize their traditional teaching role in higher education.
Concrete structures under impact

ABSTRACT The upcoming need of concrete structures designed against impulsive loading such impact requires analytical treatments comparable to those existing for structures under static loading in spite of a poor state of knowledge of material behaviour in this range of loading. This paper first presents basic relations and empirical formulae used by civil engineers for the design of concrete structures under impacts. Experimental analyses of concrete behaviour under high triaxial stress and high strain rates show that empirical formulae have to be used with care. Some recent numerical developments are also shown.
