High angular resolution study of the super star cluster population in IRAS 17138−1017

Aims. Currently, the global characteristics and evolution of super star clusters (SSCs) are not well understood, due to the large distances to their host galaxies. We aim to study the population of SSCs in IRAS 17138-1017, a luminous infrared galaxy (LIRG), in terms of age, extinction, mass, and luminosity distribution. Methods. We analyzed imaging data in the near-infrared from the GeMS/GSAOI instrument on the Gemini telescope and generated simulations with the radiative transfer code MontAGN. The extraction of SSCs from the images and their photometry in J, H, and Ks allowed us to derive color-color and color-magnitude diagrams. Comparison with a theoretical stellar evolutionary track gives a first hint into the extinction towards each SSC, as well as their ages, despite some degeneracy between those two quantities. Spectra given by our radiative transfer code MontAGN, which includes dust emission, also provide insightful predictions and comparisons. Results. We detect with a fair degree of confidence 54 SSCs of mKs between 16 mag and 21 mag with a median instrumental uncertainty of 0.05 mag. When plotted on a color–color diagram and a color–magnitude diagram, it appears that most of the sources are very much extinct with respect to an intrinsic theoretical evolutionary track. Once de-reddened, the colors point unambiguously to two distinct and very recent starburst episodes at 2.8 and 4.5 Myr. While the SSCs in the 4.5 Myr starburst are distributed along the spiral arms, the 2.8 Myr SSCs are concentrated in the central region. The luminosity and mass functions present a classical power-law behavior, although with shallower slopes than generally observed in LIRGs. Comparison with radiative transfer simulations shows that, the dust thermal emission and scattered light are negligible and could not explain the few very red SSCs that could not be de-reddened safely.
Cyanoacetamide in Heterocyclic Chemistry: Synthesis, Antitumor and Antioxidant Activities of Some New Benzothiophenes

Cyanoacylation of 2-amino-tetrahydrobenzothiophene-3-carboxylate ethyl ester with 3-(3,5-dimethyl-1H-pyrazol-1-yl)-3-oxopropanenitrile afforded cyanoacetamide 2. The later was utilized as key intermediate for the synthesis of 3-substituted 2-iminocoumarins 3, 4, 5, 6 and acrylamides 7a, b via Knoevenagel condensation with 2-hydroxy-1-naphthaldehyde; 2-hydroxybenzaldehyde; 1-nitrosonaphthalen-2-ol; 7-hydroxy-5-methoxy-2-methyl-4-oxo-4H-chromene-6-carbaldehyde; 4-dimethylamino-benzaldehyde; and 4-piperidin-1-yl-benzaldehyde in EtOH/piperidine. The derivatives 7a, b did not afford the pyrazoles 8a, b upon treating with phenyl hydrazine. Furthermore, coupling of 2 with 4-amino-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one and 4,6-dimethyl-1H-pyrrolo[2,3-b]pyridin-3-amine afforded the hydrazone derivatives 9 and 10, respectively. The later derivative 10 was cyclized in acetic acid to afford the pyridopyrazolotriazine 11. Finally, 2 was treated with dimethylformamide-dimethylacetal (DMF-DMA) to afford the dimethylaminoacrylamide 12 which underwent transamination with 4,6-dimethyl-1H-pyrrolo[2,3-b]pyridin-3-amine to afford the pyrazole 13. Cyclization of compound 13 in acetic acid or pyridine was unsuccessful. The antitumor and antioxidant activities of the synthesized products were evaluated; several were found to exhibit promising antioxidant activities. J. Heterocyclic Chem., (2011).
Optimization of In Situ Backwashing Frequency for Stable Operation of Anaerobic Ceramic Membrane Bioreactor

The cost-effective and stable operation of an anaerobic ceramic membrane bioreactor (AnCMBR) depends on operational strategies to minimize membrane fouling. A novel strategy for backwashing, filtration and relaxation was optimized for stable operation of a side stream tubular AnCMBR treating domestic wastewater at the ambient temperature. Two in situ backwashing schemes (once a day at 60 s/day, and twice a day at 60 s × 2/day) maintaining 55 min filtration and 5 min relaxation as a constant were compared. A flux level over 70% of the initial membrane flux was stabilized by in situ permeate backwashing irrespective of its frequency. The in situ backwashing by permeate once a day was better for energy saving, stable membrane filtration and less permeate consumption. Ex situ chemical cleaning after 60 days’ operation was carried out using pure water, sodium hypochlorite (NaOCl), and citric acid as the order. The dominant cake layer was effectively reduced by in situ backwashing, and the major organic foulants were fulvic acid-like substances and humic acid-like substances. Proteobacteria, Firmucutes, Epsilonbacteria and Bacteroides were the major microbes attached to the ceramic membrane fouling layer which were effectively removed by NaOCl.
Identifying, understanding and controlling defects and traps in halide perovskites for optoelectronic devices: a review

In the past decade, halide perovskite materials have captivated a great deal of attention for the application in optoelectronic devices. To realize the commercialization of optoelectronic devices made from this exhilarating material system, in particular to boost the efficiency and the stability, the formation mechanisms of defects, their impact on device performance and lifetime and the way to overcome them must be thoroughly investigated. In this review, the current understanding of the defect creation mechanism in as-synthesized and environment-exposed samples will be presented. The defect induced phenomenon and their impact on the material properties and device performances will be explained. The various defect characterization techniques will be summarized regarding their working principles and limitations. The defect engineering including both physical and chemical methods will be discussed in detail. We believe that although there are still unsolved puzzles in the field, the research on the defect mechanism and engineering is of great significance in making halide perovskites into real applications.
Combination of multi-scale and residual learning in deep CNN for image denoising

To better restore a clean image from a noise observation under high noise levels, the authors propose an image denoising network based on the combination of multi-scale and residual learning. Instead of using filters with different large sizes in traditional multi-scale schemes, they arrange multi-layer convolutions with the filters of the same size to speed up the model. Some dilated convolutions of different rates are combined with the common convolutions to enrich the extracted features in multi-layer convolutions. Furthermore, they cascade the multi-layer convolutions with residual blocks to improve the performance of image denoising. Their extensive evaluations on several challenging datasets demonstrate that the proposed model outperforms the state-of-art methods under all different noise levels in terms of peak signal-to-noise ratio, and the visual effects achieved by the proposed model are also better than the competing methods.
Nuclear mitochondrial DNA (numt) in the Atlantic rock crab Cancer irroratus Say, 1817 (Decapoda, Cancridae)

A study on the origin of a newly colonized population of the Atlantic rock crab, Cancer irroratus Say, 1817, in Icelandic coastal waters based on mtDNA variation revealed a challenging problem. Variation of the mitochondrial cytochrome oxidase subunit I gene (COI), which has played a pivotal role in phylogeographic studies, was assessed. Most individuals were found to carry two or more different genetic fragments and several ambiguous sites, with two segregating nucleotides, both within the Icelandic population and in samples from North America (Newfoundland, New Brunswick and Nova Scotia). Analyses of the DNA fragments, from clones and separate DNA extractions from the mitochondria and nucleus from undeveloped eggs and their mothers, support that ambiguous sites are caused by mitochondrial fragments incorporated in the nuclear genome (numts). A comparison of the variation in the newly colonized population in Iceland and the North American populations did not reveal any detectable bottleneck in the Icelandic population.
Diurnal variation in ultrasonographic dimensions of thyroid gland

Abstract Aim: To evaluate thyroid volume at the circadian nadir and peak of TSH levels. Subjects and methods: Serum TSH, fT3 and fT4 levels and thyroid volumes were measured at 08.00 am and 24.00 in 55 (20 male, 35 female) euthyroid healthy individuals. Results: Mean TSH level were significantly lower at 08.00 h than at at 24.00 h (1.95 ± 1.29 vs 2.52 ± 1.5 μIU/ml, respectively; p < 0.001). Mean thyroid volume was also significantly lower at 08.00 h than at 24.00 h (15.09 ± 4.97 vs. 17.38 ± 3.49; p < 0.001). There was no relationship between TSH level and thyroid volume at either time point. Conclusion: Although thyroid volume and TSH levels increase at midnight compared to 08.00 h, there is no relationship between these two parameters. We suggest that thyroid volume measurements should be performed in the morning hours.
Strategies for Improved Water Use Efficiency (WUE) of Field-Grown Lettuce (Lactuca sativa L.) under a Semi-Arid Climate

Water use efficiency is a main research target in agriculture, which consumes 70% of global freshwater. This study aimed at identifying sustainable water management strategies for the lettuce crop in a semi-arid climate. Three independent experiments were carried out on a commercial variety of lettuce (Lactuca sativa L.) by applying different irrigation levels based on crop evapotranspiration (ETc), estimated through both the Hargreaves–Samani and Penman–Monteith equations. In the first experiment, one treatment was also guided by soil moisture sensors. In the second and third experiments, a factorial combination was used, combining the different irrigation levels with two soil mulching treatments, namely soil without mulch, and soil mulched with dried rice straw residues. The application of different irrigation levels significantly affected plant growth, yield, and physiology. Both the adoption of sensors for guiding irrigation and the application of mulching with straw promoted higher yield. As the irrigation water level was reduced, the WUE (water use efficiency) increased. WUE was also increased by covering the soil with mulch. The experiments point out that accurate management of irrigation water using a drip irrigation system associated with soil mulching increases yield and improves the WUE of lettuce crops in the Central Dry Zone, Myanmar.

Individual Cortical Entropy Profile: Test–Retest Reliability, Predictive Power for Cognitive Ability, and Neuroanatomical Foundation

Abstract The entropy profiles of cortical activity have become novel perspectives to investigate individual differences in behavior. However, previous studies have neglected foundational aspects of individual entropy profiles, that is, the test–retest reliability, the predictive power for cognitive ability in out-of-sample data, and the underlying neuroanatomical basis. We explored these issues in a large young healthy adult dataset (Human Connectome Project, N = 998). We showed the whole cortical entropy profile from resting-state functional magnetic resonance imaging is a robust personalized measure, while subsystem profiles exhibited heterogeneous reliabilities. The limbic network exhibited lowest reliability. We tested the out-of-sample predictive power for general and specific cognitive abilities based on reliable cortical entropy profiles. The default mode and visual networks are most crucial when predicting general cognitive ability. We investigated the anatomical features underlying cross-region and cross-individual variations in cortical entropy profiles. Cortical thickness and structural connectivity explained spatial variations in the group-averaged entropy profile. Cortical folding and myelination in the attention and frontoparietal networks determined predominantly individual cortical entropy profile. This study lays foundations for brain-entropy-based studies on individual differences to understand cognitive ability and related pathologies. These findings broaden our understanding of the associations between neural structures, functional dynamics, and cognitive ability.
Repairing Police Psychological Safety: The Role of Career Adaptability, Feedback Environment, and Goal-Self Concordance Based on the Conservation of Resources Theory

The purpose of this study is to investigate the role of career adaptability, feedback environment, and goal-self concordance in improving police psychological safety. Questionnaires with integral and regular answers were collected from 295 police officers from four provinces in China. The police officers completed a questionnaire that included items measuring goal-self concordance, supervisor feedback environment, psychological safety, and demographics. In a separate questionnaire, each supervisor rated the subordinate’s career adaptability. Career adaptability indirectly influences psychological safety through the feedback environment. Career adaptability has a greater influence on improving psychological safety for police officers with lower goal-self concordance than for individuals with higher goal-self concordance. Police officers with lower goal-self concordance must care about their future work roles, control their personal professional activities, make education and career choices based on curiosity, and be confident in their own careers to improve their psychological safety.
The Use of Autogenous Bone Mixed with a Biphasic Calcium Phosphate in a Maxillary Sinus Floor Elevation Procedure with a 6-Month Healing Time: A Clinical, Radiological, Histological and Histomorphometric Evaluation

Background: In this study it is evaluated whether autogenous bone mixed with biphasic calcium phosphate (BCP) used in a maxillary sinus floor elevation (MSFE) leads to improved bone formation. Materials and methods: In five patients a unilateral MSFE was performed. Histological and histomorphometric analyses were performed on bone biopsies that were obtained 6 months after MSFE during dental implant surgery. Results: The average vital bone volume was 29.9% of the total biopsy (BV/TV, SD ± 10.1) of which 7.1% was osteoid (OV/BV, SD ± 4.8). The osteoid surface (OS/BS) covered 26.0% (SD ± 13.4) of the bone surface. The BS/TV covered 4.7 mm2/mm3 (SD ± 2.3). Compared with previous studies the analyses showed a difference for trabecular thickness (Tb.Th.) and osteoid surface (OS/BS), but not for BV/TV, OV/BV and the number of osteoclasts. Conclusion: MSFE with autogenous bone mixed with BCP shows an amount of newly formed bone that is comparable with the findings from the previously published 6-month study with pure BCP. However, a better distribution of the new bone over the entire biopsy was observed.
Toward Efficient Compressed-Sensing-Based RFID Identification: A Sparsity-Controlled Approach

Radio-frequency identification (RFID) has pervasive applications in building ultralow-power ubiquitous networks, where backscatter communication during tag identification is neither reliable nor efficient. Inspired by the sparsity that only a few RFID tags communicate with the reader simultaneously, many compressed sensing (CS)-based schemes have been proposed to exploit the colliding tag responses to facilitate efficient tag identification. However, most of them suffer from huge ID search space and signature collision during the CS recovery process. To address these issues, we propose SCRIC, a novel sparsity-controlled RFID identification scheme using a random signature assignment, which achieves a faster and more robust identification performance. Specifically, to tackle identification failure caused by severe signature collision, we assign each active tag an access probability to control the sparsity and reduce signature collision. Theoretical analysis is given to prove that the signature collision probability of the proposed scheme is reduced compared with the existing random signature scheme and an optimal access probability is derived. Moreover, considering that conventional CS recovery algorithm relies heavily on the unpractical assumption that the active tag number is known precisely in advance, we integrate the cross validation (CV) into CS recovery algorithms and propose a greedy algorithm called the CV-based orthogonal matching pursuit (OMP-CV), which can reduce the tag identification false alarm rate without any prior knowledge. Extensive experimental results show that the proposed mechanism significantly outperforms the existing CS-based tag identification methods in terms of identification speed and robustness to noise.
Bacterioplankton community composition in Portuguese water bodies under a severe summer drought

In 2005, a severe drought occurred in Portugal, with several reservoirs becoming dry in the southern region. A set of 20 Portuguese water bodies were analysed through denaturing gradient gel electrophoresis (16SrDNA-DGGE) and DNA sequencing to assess its bacterioplankton diversity under these particular conditions. Environmental parameters were determined to assess the trophic conditions of each water body. Most water bodies fell into the meso-to eutrophic and hypereutrophic state. In general, the levels for conductivity, pH and total suspended solids were higher than the average data from previous years. Dominant phylotypes belonged to Cyanobacteria, Actinobacteria Alphaproteobacteria, Betaproteobacteria and Bacteroidetes groups. Despite the geographic distance, common phylotypes could be recorded among water bodies. Bacteroidetes dominated at Sousa River and were related to high nutrient levels. Cyanobacteria dominated at Alentejo reservoirs and correlated with higher conductivity values. However, Actin.
The performance of an acoustic levitator

An acoustic levitator uses an array of ultrasonic transducers to generate a standing acoustic pressure field which exerts a radiation force on small particles, allowing the particles to be trapped, relocated, separated or combined. Experiments on levitating particles of different densities and calculations of the acoustic radiation force and moment have been reported in the literature. However, direct inspection on the acoustic pressure field pattern is seldom carried out. This paper reports an investigation on the performance of an existing acoustic levitator design, which uses off-the-shelf components, by comparing the visualized pressure field from Schlieren imaging to analytical simulations. The ability to compare Schlieren imaging results to analytical simulations readily can prove to be a vital tool. Since the simulations provide an ideal pressure field, the imaging of the levitator pressure field can highlight discrepancies between the real and ideal cases. This can be especially useful as a diagnostic tool to identify the cause of a drop in performance of the acoustic levitator in a real world scenario.
Genetic Association Between Herd Survival and Linear Type Traits in Holstein Cows Under Tropical Conditions

The objective of this study was to estimate genetic parameters for survival measures from birth to 60 and 72 months of age, as well as survival up to 48 and 54 months after first calving. The genetic association of these measures with 20 linear type traits and final score in Holstein cows, born between years 1990 to 2004, was also evaluated. The components of (co)variance were estimated by Bayesian methods, using the programme THRG1BBS1F 90 in bivariate analyses, considering animal threshold model for measures of survival, and animal linear model for linear type traits. The mean posterior heritability for the measures of survival ranged from 0.09 to 0.15, and for those of the linear type traits ranged from 0.07 to 0.36. The posterior genetic correlation between linear type traits and measures of survival varied from -0.37 to 0.50, respectively. Indirect genetic selection for udder depth, rear teat placement, udder texture, bone quality, fore udder attachment, body depth and chest width may lead to correlated gains in longevity in Holstein cows under tropical conditions.
Trade Shocks and Growth: The Impact of the Quartz Crisis in Switzerland

Agglomeration economies and clustering effects are a key driver of urban growth. They can also be a source of vulnerability when cities and regions specialize in export-intensive industries. Foreign competition and technological change can threaten the survival of exporters, and shocks to these industries can have long-run effects on the communities which rely on them. In this paper, I study the impact of a rapid and large-scale trade shock: The quartz crisis, which devastated the globally dominant Swiss watch industry in the 1970s. I document the geographic agglomeration pattern of the industry and the impact of the crisis on exports, employment, and wages. Using a differences-in-differences strategy, I show that this trade shock led to a large and rapid loss of population in affected areas, and a long-run change in growth patterns. I explore the mechanisms behind this population change, including the role of manufacturing employment and immigration. I discuss the implications of these results for theories of urban growth, and contrast them with recent work on the China shock in Europe and the United States.
Predicting Fishing Participation and Site Choice While Accounting for Spatial Substitution, Trip Timing, and Trip Context

Abstract We developed choice models to understand and predict the amount, timing, and locations of recreational fishing trips taken by anglers in northwestern Ontario, Canada. These models incorporated several improvements over previous models to account for complex patterns of spatial substitution among fishing sites, the context of fishing trips, and the importance of tradition and weather on the timing of trips. Joint models of fishing participation and site choice were developed for two resident populations of anglers from northern Ontario. For both populations, the three innovations provided significant improvements to the models and important information for understanding and predicting recreational fishing behaviors. The utility of the model to fisheries managers was illustrated through a management scenario that involved the restoration of walleyes Sander vitreus in a large water body. The forecasts suggested that the effect of this restoration on fishing effort at other waters was influenced by s.
Method of Buildings Structural Vulnerability and Geometry Form Designs Evaluation Towards Earthquakes With The SVA Architectural Design

In the process of architectural design, there is no special method employed by architects to evaluate buildings’ structural vulnerability and building geometry form designs towards earthquakes. Therefore, the alternative is adapting the existing method called SVA-Retrofit. JBDPA and Matsutaro Seki developed this method, and then the author adapted this method now called SVA Architectural Design. In the process of adaptation, deep literature review was conducted in order to acquire the adaptation results of the SVA-Architectural Design. The SVA analysis was then compared with the pushover analysis, and the results of SVA were actually accurate enough to predict the building vulnerability toward earthquakes. These results can furthermore be an early prediction of structural vulnerability toward earthquakes that eventually leads to finding solutions for building designs or conducting detailed analysis done by structure experts.
