Electrophoretic deposition of iron oxide nanoparticles to achieve thick nickel/iron oxide magnetic nanocomposite films

For modern switching power supplies, current bulk magnetic materials, such as ferrites or magnetic metal alloys, cannot provide both low loss and high magnetic saturation to function with both high power density and high efficiency at high frequencies (10-100 MHz). Magnetic nanocomposites comprised of a ferrite and magnetic metal alloy provide the opportunity to achieve these desired magnetic properties, but previously investigated thin-film fabrication techniques have difficulty achieving multi-micrometer film thicknesses which are necessary to provide practical magnetic energy storage and power handling. Here, we present a versatile technique to fabricate thick magnetic nanocomposites via a two-step process, consisting of the electrophoretic deposition of an iron oxide nanoparticle phase into a mold on a substrate, followed by electro-infiltration of a nickel matrix. The deposited films are imaged via scanning electron microscopy and energy dispersive X-ray spectroscopy to identify the presence of iron and nickel, confirming the infiltration of the nickel between the iron oxide nanoparticles. A film thickness of ∼7 μm was measured via stylus profilometry. Further confirmation of successful composite formation is obtained with vibrating sample magnetometry, showing the saturation magnetization value of the composite (473 kA/m) falls between that of the iron oxide nanoparticles (280 kA/m) and the nickel matrix (555 kA/m). These results demonstrate the potential of electrophoretic deposition coupled with electro-infiltration to fabricate magnetic nanocomposite films.For modern switching power supplies, current bulk magnetic materials, such as ferrites or magnetic metal alloys, cannot provide both low loss and high magnetic saturation to function with both high power density and high efficiency at high frequencies (10-100 MHz).

The complete chloroplast genome sequence of Mangifera sylvatica Roxb. (Anacardiaceae) and its phylogenetic analysis

Abstract In this study, we firstly reported the complete chloroplast (cp) genome sequences of the Mangifera sylvatica from Nanning, Guangxi province, China. The complete wild mango cp genome size is 158063 bp with a typical small single-copy region (SSC, 18340 bp), a large single-copy region (LSC, 87008 bp) and a pair of inverted repeats (IRs, 26379 bp and 26379 bp respectively). Out of 112 unique annotated genes in mango cp genome, 78 found to be protein coding, 30 to be tRNA and 4 rRNA genes. Besides, we found 51 microsatellite sequences (SSRs) in the cp genome. Sequence alignment and ML analysis of 29 full plastome data revealed M. sylvatica shares the closest relationship with cultivated mango (M. indica) and form a sister group with Rhus chinensis within Anacardiaceae.
Effect of germination and roasting on the proximate composition, total phenolics, and functional properties of black chickpea (Cicer arietinum)

Germinated and microwave roasted black chickpea were evaluated for physical, proximate, pasting, functional, and antioxidant properties. A significant variation was observed in quality of grain upon germination and roasting. The effect of germination and roasting on functional groups was analyzed using Fourier‐transform infrared spectroscopy. The results showed that germination improved the physical and pasting properties, whereas roasting enhanced the functional properties. The lightness of germinated grains significantly improved as compared with dark colored roasted sample. The germinated sample was found rich in protein, whereas carbohydrates and fiber content increased in roasted sample. Water and oil absorption content were reduced by 7.14% and 5.13% in germination as compared with control. However, roasting significantly improved the water absorption capacity and oil absorption capacity by 69.51% and 6.41% as compared with control.
On Noise and Interference Modeling for Over-the-air Testing of MIMO Terminals

As the fifth generation (5G) ecosystem matures, the time for large-scale 5G radio commercialization is now. Over-the-air (OTA) radiated testing is seen to replace currently dominantly adopted cable conducted testing for upcoming radio systems due to integrated antenna designs. To properly evaluate performance of radio systems in fading channel conditions, it is typically needed to model the realistic signal, interference and noise conditions in the testing environment. However, interference and noise modeling is largely overlooked in the literature in OTA testing, since the discussion is typically focused on the signal alone. In this paper, interference and noise modeling in three OTA setups, including the multi-probe anechoic chamber (MPAC), radiated two stage (RTS) and reverberation chamber (RC) is discussed and summarized.

A Truthful Online Mechanism for Collaborative Computation Offloading in Mobile Edge Computing

Collaborative computation offloading in mobile edge computing where edge users offload tasks opportunistically to resourceful neighboring mobile devices (MDs), offers a promising solution to satisfy low-latency requirements. However, most existing works assume that those MDs volunteer to help edge users without an incentive mechanism. In this article, we propose an auction-based incentive mechanism, where users and MDs participate in the system dynamically. Our auction mechanism runs in the online fashion and optimizes the long-term system welfare without knowledge of future information, e.g., task start time, task length, resource demand, and valuation, etc. We prove that the proposed online mechanism achieves the desired properties, including individual rationality, truthfulness, and computational tractability. Moreover, the theoretical competitive ratio shows that our online mechanism achieves near-optimal long-term social welfare close to the offline optimum. Extensive experiments based on real-world traces demonstrate the efficiency of the proposed online mechanism.

Modifying the maximal light-use efficiency for enhancing predictions of vegetation net primary productivity on the Mongolian Plateau

ABSTRACT Maximal light-use efficiency (LUE), ɛmax, is a measure of the conversion efficiency of the photosynthetically active radiation absorbed by plants to net primary productivity (NPP), based on the principle that an optimal plant productive capability exists when the LUE is at its maximum. ɛmax is an important parameter for modelling regional NPP and is conventionally applied at the biome level using a constant value. In this study, we estimated type-specific ɛmax values for three dominant land cover types on the Mongolian Plateau: 0.621 g C MJ–1 (MJ is the mega Joules and 1 MJ = 106 J) for meadow steppe, 0.534 g C MJ–1 for typical steppe, and 0.520 g C MJ–1 for desert steppe. With these steppe-specific modified ɛmax values, we were able to examine changes in NPP for 2001–2015 on the plateau, as well as their likely responses to regional climate change. The use of different ɛmax values for each steppe type improved the accuracy of the Carnegie Ames Stanford Approach (CASA) Biosphere model predictions of grassland NPP by 18.8% (R2 = 0.48 to R2 = 0.57; R2 is the coefficient of determination) over the observation period. Previous studies based on a constant ɛmax (0.541 g C MJ–1) appear to underestimate ɛmax and NPP in meadow steppe, highlighting the importance of setting type-specific ɛmax values for different land cover types in the remote-sensing modelling of grassland NPP. However, more detailed maps of biome sub-classes, with species composition, would be valuable for future attempts to determine appropriate ɛmax values. The growing season (April–October) NPP on the plateau increased significantly from 2001 to 2015, with an annual increment of 4.44 g C m–2 y–1. This trend was strongly governed by the change in summer NPP across the plateau. In comparison, NPP in the spring and autumn did not influence the change in total NPP, which was likely due to their relatively small values. Summer precipitation and the related drought stress were the chief factors responsible for plateau-scale NPP changes, due to the high proportion of summer precipitation and NPP in the annual totals. This may induce important environmental features, such as dzud (a Mongolian term for a severe winter) and desertification on the plateau.
In the army now … Evaluating an intensive training program for youth

ABSTRACT We assess the impacts of one of the most intensive youth support and training programs in France: the Voluntary Military Service (VMS), piloted by the army since 2015. Our evaluation allows us to compare the cohort of young people entering the VMS with a cohort of unincorporated young volunteers. Our results indicates that a passage through the VMS increases chances of getting a job, especially for youth under 21 years of age. It also highlights other positive impacts of this pilot scheme and explores the means by which this effect is expressed: improved mobility and the obtention of a qualification.
Anti-Nutritional Factors & Its Roles in Animal Nutrition

It is well known that nutrition is one of the main factors driving the functioning efficacy, efficiency and evolution of livestock system. The main challenges nowadays in ruminant production are to reduce feeding cost, improve products quality and diminish the impact of production on environment. The use of unconventional feedstuffs may contribute to decrease feeding cost and environmental impact through reduced methane emissions as well. Not only that, but shrubby plants can be used to combat desertification, mitigating the effect of drought, allowing soil fixation an enhancing the restoration of the vegetation and the rehabilitation of rangelands. In the meantime, browsing tree foliage plays an important role in ruminant feeing systems in many tropical and Mediterranean environments around the world [1]. They are chiefly as good, cheap sources of nitrogen and energy, which may reduce feeding cost and raise sheep productivity in arid and semi-arid zone [2]. So, to reach that goal, it must exploit all that is available either unconventional feedstuffs or browse and shrubs. However, the problems of feeding such plants or shrubs (Acacia, Leucaena and Atriplex) that they had different levels of anti-nutritional factors.
Microbiota analysis in rheumatoid arthritis: News and perspectives

In the last decade, our knowledge regarding the importance of the microbiome (i.e., the genes of the microbiota) in the pathophysiology of Rheumatoid Arthritis (RA) was transformed with the development of next generation sequencing techniques that now allow an overview of the totality of a host microbiome (defined as the species of microorganisms, such as bacteria, phages, viruses and fungi). Indeed, gut dysbiosis, that characterizes RA, evolves during the history of the disease with modifications observed at the preclinical stage and even more at the onset of the clinical disease in untreated and active patients. In those patients receiving treatment a partial correction is reported particularly when remission is achieved. Although incomplete, similar observations are noted when exploring mouth and lung microbiota. Dysbiosis reflects a loss of anti-inflammatory species and an overrepresentation of pro-inflammatory species (e.g. Prevotella copri, Collinsella aerofaciens) or species that promote citrullination and, in turn, anti-citrullinated peptide antibodies (ACPA) autoantibody production (e.g. Cryptobacterium curtum, Haemophillus species). Moreover, gut, mouth and lung dysbiosis are suspected of being involved in the origin of bacterial nucleic acids detected in the synovium of RA patients. Therefore, better knowledge of the microbiota during the course of the disease can open new perspectives regarding the prevention, diagnosis, and treatment of RA patients as reviewed. *Correspondence to: Yves Renaudineau, Laboratory of Immunology and Immunotherapy, Brest University Medical School Hospital, BP 824, F-29609, Brest, France, Tel: 33-298-22-33-84; Fax: 33-298-22-38-47; E-mail: yves. renaudineau@univ-brest.fr
An efficient solar energy harvesting system for wireless sensor network nodes

Abstract A wireless sensor network is a network of spatially deployed sensor nodes with constrained energy resources. This research paper focusses to design a robust solar energy harvesting system to enhance life time of sensor nodes. Proposed solar energy supply system mainly consists of a solar panel, rechargeable battery and a control circuit. To obtain sufficient voltage to charge battery, electrical energy generated through panel is boosted by boost converter. Different sensor nodes are supplied with energy from this system. An inverter is also designed for AC applications. Complete structure of the system, design of each module, details of implementation and evaluation of performance are explained in this work. Experimental results show that this compact, self-sufficient system enables outdoor based wireless sensor network nodes to operate successfully.
Rearranjos cromossômicos e sua influência no aparecimento de novas famílias de DNA satélite em Arabidopsis

Chromosomal rearrangements and their effects on the appearance of novel satellite DNA families in Arabidopsis The centromere is composed of constitutive heterochromatin, taking part as an important chromosomal structure. Apart from being a landmark for the separation of both chromosome arms, it is responsible for the correct segregation of chromatids during the cell cycle. This structure indicates where the spindle fibers should connect to the chromosome, forming a proteic structure called kinetochore. The centromeres are composed mainly by repetitive sequences, organized in tandem arrays, called satellite DNAs. These sequences go through an evolutionary process called Concerted Evolution, which is driven by accumulation of mutations due to molecular drive mechanisms. This process ends up in a homogenization of the satDNA in a species. Some satDNA families are similar in a given group of species, such as in Arabidopsis genera. Several chromosomal rearrangements took place in this group’s evolution. Four of these alterations occurred in centromeric and pericentromeric regions, only on ancestral chromosomes 6, 7 and 8, similar to A. lyrata modern karyotype, that gave place to modern A. thaliana chromosomes 4 and 5. The three 180bp satDNA families present in this ancestral karyotype differ from the single one present in modern A. thaliana karyotype. Moreover, this single family appears in all five chromosomes of this species. This gives rise to a few questions, of how did the A. thaliana 180bp satDNA family present appeared in all of its five chromosomes, since the alterations only occurred in chromosomes 4 and 5? And what happened to the other families present in the ancestral karyotype? In order to answer these questions, bioinformatic procedures were performed. The first step was to locate the centromeres on the sequencing available on the database (https://plants.ensembl.org/). In the case of A. thaliana, the software JDotter was used to construct a DotPlot to locate repetitive sequences, and in the case of A. lyrata a Blast was performed on the database with the sequences presented in the literature. Then, the software Tandem Repeats Finder was used to locate and extract the 180bp satDNA families. The sequences were organized using BioEdit and aligned on MEGA7 software. A Maximum Likelihood tree was constructed, and showed a clear separation between both species, and that in A. thaliana, sequences from chromosomes 4 and 5 intermingled in some regions. This shows that there is a different homogeneity between these sequences, even though they are members of the same family. This result hints that changes in the genomic context due to the chromosomal rearrangements influence the homogenization process in these satDNA sequences, and thus, influencing the concerted evolution.
Genetic Improvement, Propagation And Conservation Efforts For Tecomella Undulata, A Flagship Timber Species Of The Drylands- A Review

Tecomella undulata (Local name-Rohida) which belongs to the family Bignoniaceae is a socially acceptable and economically valuable tree species of the arid regions and native to the Indian subcontinent. It is a well-known multipurpose tree species that has been over exploited for timber and medicines from its natural habitat. As a result, most Rohida genetic resources have already been depleted in the wild habitat. Therefore, to conserve the species tree improvement programmes are underway in different organisations. Under tree Improvement research on Rohida, work has been majorly carried out on reproductive biology, selection of candidate plus trees, establishment of progeny trials, vegetative propagation, and diversity studies using molecular markers. The report consolidates the status of the work on tree improvement and propagation of this important tree species done so far.
Coagulation factor activity and clinical bleeding severity in rare bleeding disorders : results from the European Network of Rare Bleeding Disorders

Abstract 3312 [][1] The European Network of Rare Bleeding Disorders (EN-RBD) was established to bridge the gap between knowledge and practice in the care of patients with RBDs (rare bleeding disorders frequency <1/0.5-2M). The aim of this first report was to explore the relationship between the coagulation factor activity levels and clinical bleeding severity in patients with RBDs. A total of 592 records on patients with RBDs were cross-sectionally collected over a period of three years. Data on clinical bleeding episodes were available for 495 patients and were classified into four categories according to severity. The mean age of patients was 31 years (range, 7 months-95 years), with 51% being females. On linear regression analysis, there was a strong association between coagulation factor activity level and clinical bleeding severity for fibrinogen, factor (F)FX, FXIII, and combined FV and FVIII deficiencies. A weaker association was present for FV and FVII deficiencies. There was no association between coagulation factor activity level and clinical bleeding severity for FXI. It is of clinical relevance to identify levels that are not associated with spontaneous major bleeding, which was done by constructing receiver operating characteristic curves. These levels were highest for FXIII deficiency (25 U/dl), followed by FV+VII (15 U/dl), FVII (15 U/dl), FX (5 U/dl), and FV (1 U/dl) deficiencies. For fibrinogen deficiency, a factor activity level of 20 mg/dl is needed to ensure absence of major spontaneous bleeding. There is a clear relation between coagulation factor activity level and clinical bleeding severity in RBDs, which is different for the missing clotting factor.

Biodiversité fonctionnelle en paysage agricole : étude floristique et syrphidologique de Surfaces de Promotion de la Biodiversité (SPB)

Description du sujet. Cette étude traite de la végétation et des Diptères Syrphidae au sein de Surfaces de Promotion de la Biodiversité (SPB) de type « prairies extensives » en contexte agricole. Objectifs. L’objectif consiste à tester l’influence des facteurs « taille » et « qualité botanique » des SPB sur la syrphifaune qui s’y développe. Il s’agit également de rechercher les relations entre la végétation et les syrphes, ainsi que de mettre en avant le potentiel de lutte biologique de ces surfaces. Méthode. Douze SPB ont été sélectionnées, sur la base de leur taille (< 3 000 m2 vs > 9 000 m2) et de leur niveau de qualité botanique établi sur la base de la présence d'espèces végétales indicatrices. Des inventaires de végétation ont été réalisés dans chacune des SPB, l’échantillonnage des syrphes a été effectué par la pose de deux pièges à émergence et d’un piège Malaise par site. Résultats. Indépendamment de leur taille ou de leur niveau de qualité botanique, les SPB abritent et attirent une faune syrphidologique majoritairement aphidiphage au stade larvaire. Les fleurs de couleur jaune et blanche ainsi que celles produisant du nectar influencent la richesse et l'abondance en syrphes. Conclusions. Le potentiel des SPB à abriter et attirer des syrphes aphidiphages montre qu'elles sont en mesure d’offrir un service de lutte biologique contre les ravageurs des cultures adjacentes.
