Somewhere in between: Tracing the Radio Emission from Galaxy Groups (or Why Does the Future of Observing Galaxy Groups with Radio Telescopes Look Promising?)

Galaxy groups constitute the most common class of galaxy systems in the known Universe, unique in terms of environmental properties. However, despite recent advances in optical and infrared observations as well as in theoretical research, little is known about magnetic fields and the associated continuum radio emission. Studies on this issue have only been conducted in recent years, and many questions have yet to be resolved. This article aims to put the study of group magnetism in a broader context, to present recent advances in the field (mainly achieved with low-frequency radio interferometers), and to list the issues that need to be addressed in future observations. To make it easier for the Readers to get acquainted with the concepts presented in the manuscript, radio observations of two sample groups of galaxies are also presented.
Multi-Wavelength Observations of a Failed Filament Eruption and Associated Hovered Coronal Mass Ejection

Failed filament eruption remains mysterious on its initiation, magnetic environment, and erupting and failing mechanisms. We present multi-wavelength observations of a failed filament eruption and its associated hovered coronal mass ejection (hovered-CME) from limb observations of the Ahead of Solar Terrestrial Relations Observatory. On-disk observations from Solar Dynamics Observatory show the expansion of the anchored leg of an S-shaped filament during the pre-eruption phase. The main eruption starts as a sudden ejection of the erupted leg, which is followed by the appearance of EUV brightening in the S-shaped magnetic field. The brightening is spatio-temporal accompanied with hard X-ray emission enhancement, and cancellation of opposite magnetic polarities, which imply possible reconnection. After reaching the maximum displacement, the erupted material drains back to the Sun along the remaining anchored leg. The non-linear force free magnetic field extrapolation shows an S-shaped magnetic field, formed by two magnetic structures, with a strong enveloped magnetic field. The decay index at the possible apex of the filament is 0.8–1.2. Observations indicate that the failed filament eruption is triggered by tether cutting reconnection and is possibly confined by the upper magnetic field. The hovered-CME, resulting from the failed filament eruption and recording as a coronal mass ejection (CME), may cause the overestimation of the CME count.
Intelligent 3D Objects Classification for Vehicular Ad Hoc Network Based on Lidar and Deep Learning Approaches

Works that use point cloud avoid wasting time and cost of collection, using simulators and datasets available in the literature. In this way, there is access to an unlimited and organized amount of point clouds, an ideal setting for deep learning networks and Vehicular ad hoc networks (VANETs). However, models trained with synthetic data present problems when applied to real-world data.This work proposes the use of deep learning in the recognition of 3D objects captured with a Light Detection and Ranging (LIDAR), including a pre-processing stage. In addition, it is proposed two datasets, a real-world and a syntetic; each dataset includes three classes. A method of pre-processing is proposed to circumvent the distribution discrepancies of the proposed datasets and the existing datasets from literature, such as ModelNet. We use deep learning with the PointNet method, as it supports raw data from point clouds as input to the network. We performed three evaluation approaches: training and testing steps with the proposed datasets using <xref rid="deqn1" ref-type="disp-formula">(1)</xref> Lidar3DNetV1, which is a proposed network in this paper, <xref rid="deqn2" ref-type="disp-formula">(2)</xref> PointNet, and (3) classification of ModelNet datasets using Lidar3DNetV1. The proposed network achieved 98.33% of accuracy and a testing time of <inline-formula> <tex-math notation="LaTeX">$88~\mu \text{s}$ </tex-math></inline-formula> in the synthetic dataset, while in the real-world dataset, the network reached 98.48% and <inline-formula> <tex-math notation="LaTeX">$145~\mu \text{s}$ </tex-math></inline-formula> in accuracy and testing time, respectively.
Effect of sole and combined application of cocoa pod husk ash and cocoa pod husk powder on growth and yield of raddish (raphanus sativus)

This study was carried out at the Teaching and Research farm Landmark University, Omu-Aran. Treatments consisted of 3 levels of cocoa pod husk ash (0, 2 and 4 tonnes CPHA ha-1), 3 levels of cocoa pod husk powder (0, 2 and 4 tonnes CPHP ha-1), NPK and the control. The experiment was laid out in a Randomized Complete Block Design (RCBD) replicated four times. The following parameters were taken plant height, number of leaves (at 2, 3, and 4 weeks after sowing), total plant weight, root weight, leaf weight, roots girth and roots length. Data collected were subjected to Analysis of Variance (ANOVA) Using S.A. S, 2000. Treatment means were compared using Duncan Multiple Range Test (DMRT) at 0.05 level of probability. Results showed that chemical analysis of cocoa pod ash and powder contained plant nutrients as N, P, K, Ca, Mg and some other micronutrients in varying proportions. Application of CPHA 4 CPHP 2 gave higher values for all the vegetative parameters. The implication of this study is that high level of cocoa pod husk powder in combination with high level of cocoa pod husk ash is detrimental to radish cultivation. In the same vein, the nutrition of radish was incomplete when NPK fertilizer was applied. It can therefore be recommended that the use of combined application of cocoa pod ash and cocoa pod powder at CPHA4 + CPHP2 was sufficient for the cultivation of radish (Raphanus sativus) in the study area as it compete favourably with application of NPK fertilizer.
Resonant precession of magnetization and precession—induced DC voltages in FeGaB thin films

Measurements of frequency dependent ferromagnetic resonance and spin pumping driven dc voltage (V dc) are reported for amorphous films of Fe78Ga13B9 alloy to address the phenomenon of self-induced inverse spin Hall effect (ISHE) in plain films of metallic ferromagnets (FMs). The V dc signal, which is anti-symmetric on field reversal, comprises of symmetric and asymmetric Lorentzians centered around the resonance field. Dominant role of thin film size effects is seen in setting the magnitude of static magnetization, V dc and dynamics of magnetization precession in thinner films (⩽8 nm). The film thickness dependence of magnetization parameters indicates the presence of a magnetically disordered region at the film—substrate interface, which may promote preferential flow of spins generated by the precessing magnetization towards the substrate. However, the V dc signal also draws contributions from rectification effects of a ≈0.4% anisotropic magnetoresistance and a large (≈54 nΩ m) anomalous Hall resistivity (AHR) of these films which ride over the effect of spin–orbit coupling driven spin-to-charge conversion near the film—substrate interface. We have addressed these data in the framework of the existing theories of electrodynamics of a ferromagnetic film subjected to radio-frequency field in a coplanar waveguide geometry. Our estimation of the self-induced ISHE for the sample with 54 nΩ m AHR shows that it may contribute significantly (≈90%) to the measured symmetric voltage. This study is expected to be very useful for fully understanding the spin pumping induced dc voltages in metallic FMs with disordered interfaces and large anomalous Hall effect.
Communication Topology Assignment and Control Co-design for Vehicle Platoons in LTE-V2V Network

In this study, we investigate the problem of inter-vehicle communication topology (IVCT) assignment and control for vehicular platoons in LTE-V2V networks based on the cooperative awareness message dissemination mechanism. A sampled-data feedback controller is proposed for platoons to eliminate the effect of stochastic packet dropouts and external disturbance, where the controller gain depends on the IVCT. To guarantee the stability requirement of a platoon with the minimized cost function, a unified control framework is established to jointly determine the optimal IVCT from all the available ones and the associated feedback controller gain. This co-design procedure is based on the optimal control and dynamic programming technique, where both fixed and periodic switching IVCTs are available. A useful algorithm is proposed to implement the established co-design framework. Furthermore, we present numerical examples to demonstrate the effectiveness of the proposed method.
Nutrition, Obesity and Asthma Inception in Children. The Role of Lung Function

Obesity is an important public health problem. WHO estimates that about 39 million children younger than 5 years of age are overweighted or obese. On the other hand, asthma is the most prevalent chronic disease in childhood, and thus, many children share those two conditions. In the present paper we review the epidemiology of children with asthma and obesity, as well as the consequences of being obese on the respiratory system. On the one hand obesity produces an underlying T-helper 2 (TH2) low inflammation state in which numerous cytokines, which could have an impact in the respiratory system play, a role. On the other hand, some respiratory changes have been described in obese children and, specially, the development of the so called “dysanapsis” (the disproportionate scaling of airway dimensions to lung volume) which seems to be common during the first stages of life, probably related to the early development of this condition. Finally, this review deals with the role of adipokines and insulin resistance in the inception and worsening of asthma in the obese child.
Different facets of dry–wet patterns in south-western China over the past 27 000 years

Abstract. Frequently occurring mega-droughts under current global climate change have attracted broad social attention. A paleoclimatic perspective is needed to increase our understanding of the causes and effects of droughts. South-western (SW) China has been threatened by severe seasonal droughts. Our current knowledge of millennial-scale dry and wet phases in this region is primarily based on the variability of the Indian summer monsoon. However, water availability over land does not always follow patterns of monsoonal precipitation but also depends on water loss from evaporation and transpiration. Here, we reconstructed precipitation intensity, lake hydrological balance and the soil water stress index (SWSI) for the last 27 000 years. Grain size, geochemical and pollen records from Yilong Lake reveal the long-term relationships and inconsistencies of dry–wet patterns in meteorological, hydrological and soil systems in the central Yunnan region, SW China. Our results show that the long-term trends among precipitation, hydrological balance and soil moisture varied through time. The hydrological balance and soil moisture were primarily controlled by temperature-induced evaporation change during periods of low precipitation such as the Last Glacial Maximum and Younger Dryas. During periods of high precipitation (the early to late Holocene), intensified evaporation from the lake surface offset the effects of increased precipitation on the hydrological balance. However, abundant rainfall and the dense vegetation canopy circumvented a soil moisture deficit that might have resulted from rising temperature. In conclusion, the hydrological balance in the central Yunnan region was more sensitive to temperature change while soil moisture could be further regulated by vegetation changes over millennial timescales. Therefore, under future climate warming, the surface water shortage in the central Yunnan region may become even more serious. Our study suggests that reforestation efforts may provide some relief to soil moisture deficits in this region.
COPYING ONE OF A PAIR OF STRUCTURES

Abstract We ask when, for a pair of structures $\mathcal {A}_1,\mathcal {A}_2$ , there is a uniform effective procedure that, given copies of the two structures, unlabeled, always produces a copy of $\mathcal {A}_1$ . We give some conditions guaranteeing that there is such a procedure. The conditions might suggest that for the pair of orderings $\mathcal {A}_1$ of type $\omega _1^{CK}$ and $\mathcal {A}_2$ of Harrison type, there should not be any such procedure, but, in fact, there is one. We construct an example for which there is no such procedure. The construction involves forcing. On the way to constructing our example, we prove a general result on modifying Cohen generics.
Family Practice Nursing in Newfoundland and Labrador: Are Reported Roles Reflective of Professional Competencies for Registered Nurses in Primary Care?

Background Family practice nurses are Registered Nurses who work collaboratively in primary care and deliver a range of services. Professional competency statements have been developed to describe the skills and knowledge of family practice nurses as a distinct field. Purpose We conducted a secondary analysis of qualitative interview data to examine how family practice nurse roles/activities relate to recently developed professional competencies. Methods Family physicians and family practice nurses in Newfoundland and Labrador (NL) participated in semi-structured interviews, during which they discussed roles/activities and scope of practice surrounding family practice nursing. For this secondary analysis, we used competency statements to inform thematic coding of the transcribed interviews. Results For the initial study, a total of 8 participants (5 family practice nurses; 3 family physicians) were interviewed from diverse practices. All transcripts from the original study (n = 8) were included in the secondary analysis and analysed across 47 competencies encompassing 6 domains (Professionalism; Clinical Practice; Communication; Collaboration and Partnership; Quality Assurance, Evaluation and Research; Leadership). Roles/activities reported by participants were reflective of the competencies, but with substantial variation in expression. Conclusions Family practice nursing competency statements reflect the actual activities of family practice nurses in NL. The professional competencies can serve as a framework to examine contributions of family practice nurses and identify areas warranting further training. The use of competencies to explore family practice nurses’ roles and activities can assist with optimizing scope of practice.
Upper Mantle Structure Beneath Mariana: Insights From Rayleigh‐Wave Anisotropic Tomography

We determine Rayleigh‐wave phase‐velocity azimuthal anisotropy tomography beneath Mariana using a large number of high‐quality amplitude and phase data of teleseismic fundamental mode Rayleigh waves at periods of 25–130 s. The obtained phase‐velocity model is then inverted for a 3D azimuthal anisotropic shear‐wave velocity (Vs) model down to ∼300 km depth. The old (∼150 Ma) Pacific oceanic lithosphere near the Mariana trench is imaged as a clear high‐Vs zone with a thickness of ∼100 km, whereas obvious low‐Vs anomalies exist in the mantle wedge and in the asthenosphere beneath the incoming plate. The Pacific oceanic lithosphere near the Mariana trench mainly exhibits a fast‐velocity direction (FVD) of NW‐SE normal to seafloor isochrons, which may reflect frozen‐in lattice‐preferred orientation formed at the mid‐ocean ridge, whereas the dominant FVD in the subducting Pacific slab at depths >∼100 km is parallel to the Mariana trench, probably reflecting subduction‐related structural deformation in the slab. Significant trench‐normal FVDs exist in the mantle wedge at depths <∼100 km, whereas the deeper portion of the mantle wedge mainly exhibits trench‐parallel FVDs, which may indicate a flow pattern in the mantle wedge due to the slab deep subduction and dehydration.
An inertial iterative scheme for solving variational inclusion with application to Nash-Cournot equilibrium and image restoration problems

Variational inclusion is an important general problem consisting of many useful problems like variational inequality, minimization problem and nonlinear monotone equations. In this article, a new scheme for solving variational inclusion problem is proposed and the scheme uses inertial and relaxation techniques. Moreover, the scheme is self adaptive, that is, the stepsize does not depend on the factorial constants of the underlying operator, instead it can be computed using a simple updating rule. Weak convergence analysis of the iterates generated by the new scheme is presented under mild conditions. In addition, schemes for solving variational inequality problem and split feasibility problem are derived from the proposed scheme and applied in solving Nash-Cournot equilibrium problem and image restoration. Experiments to illustrate the implementation and potential applicability of the proposed schemes in comparison with some existing schemes in the literature are presented.
Effect of Vernonia amygdalina leaf extract on growth performance, carcass characteristics of pullet and broiler birds

A six week experimental trial was conducted to determine “The effect of Vernonia amygdalina leaf extract on the growth performance, carcass characteristics of broilers and pullets birds”. The experiment was carried out at the poultry unit of the Teaching and Research Farm of the Niger Delta University, Wilberforce Island Bayelsa state. Forty (40) day old chicks were used for the experiment comprising of two genotypes, twenty broilers and twenty pullets. Each genotype was divided into treatment and control. The treatment was administered 50ml V. amygdalina leaf extract was diluted into 1 litre of drinking water except the control group. The result showed significant difference (P<0.05) between the control group and the group administered V. amygdalina leaf extract as they were different in carcass, live weight, heart, liver and gizzard weight for broilers. The result also showed that the experimental group was significantly different (P<0.05) from the control group in lungs weight. However, the result showed no significant difference (P>0.05) for both kidney and spleen weights for both groups. The results also show no significant difference (P>0.05) between the control and treatment group of pullets. The study recommends that the use of V. amygdalina up to the level used in this study is suitable for broiler production. It can also be used to enhance performance at the growing phase of pullet’s birds.
Teachers’ perception of the use of mobile technologies with smart applications to enhance students’ thinking skills: a study among primary school teachers in Thailand

ABSTRACT The current study examines antecedents to teachers’ behavioral intentions to use smart technologies in Thailand based on the technology acceptance model. 825 primary school teachers participated in a survey consisting of 11 constructs: perceived usefulness, perceived ease of use, attitude towards use, behavioral intention, peer influence, cognitive feedback, cognitive teaching belief, computer self-efficacy, perceived enjoyment, perceived ubiquity value, and personal innovativeness. The results suggested the proposed research model had a good model fit. 67.5% of variance in Thai teachers’ behavioral intentions was significantly associated with attitude towards use, perceived ubiquity value, cognitive teaching belief, and personal innovativeness. Attitude towards using mobile technologies was significantly associated with perceived usefulness, perceived ease of use, perceived ubiquity value, and personal innovativeness. Perceived usefulness was significantly influenced by perceived ease of use, peer influence, cognitive teaching belief, and cognitive feedback. In addition, computer self-efficacy and perceived enjoyment significantly influenced Thai teachers’ perception of ease of use.
The effect of cash holdings and corporate governance on firm value: Evidence from the Amman Stock Exchange

Much effort has been expended by the regulators in Jordan to enhance the code of corporate governance (CG); however, the effectiveness of CG mechanisms in monitoring management and enhancing the value of a firm is still a puzzle. This study aims to investigate the impact of CG and cash holdings (CH) on firm value as measured by the market-to-book ratio. The sample consists of all manufacturing firms listed on the Amman Stock Exchange (ASE) over the years 2010–2017. The study hypotheses were tested using panel regression analysis. The research findings suggest that CH have a positive association with firm value, supporting the transaction and precautionary motives for holding cash. An interesting finding is that board expertise was found to be negatively associated with firm value. Gender diversity was found to be positively related to firm value, while board size, independence, and frequency of meetings were found to be insignificant. It seems that firms in Jordan regard strong CG mechanisms to be expensive and of little value in mitigating the negative effects of a weak legal system. These findings shed new light on the influence (or the lack of it) of boards in Jordanian firms. Consequently, the study recommends that the regulatory agencies in Jordan should consider improving governance codes and Rules to increase the effectiveness of the board and governance in general.
MÉCANISMES DE FRAGILISATION PAR L'HYDROGÈNE DANS LES MÉTAUX: APPORT DES SIMULATIONS ATOMISTIQUES

Le rôle de l'hydrogène dans la rupture des alliages métalliques "de structure" a été largement démontré expérimentalement. Néanmoins, il n'existe pas de modèle quantitatif, convaincant, à l'échelle microscopique. L'une des difficultés de l'étude de ce phénomène par simulation numérique est la diversité des échelles spatiales mises en jeu. Par exemple, dans le cas "semi-fragile", il est fréquent que la "process zone" s'étende sur plusieurs grains et soit le lieu de plusieurs types de rupture, comme le montre les faciès de rupture d'aciers, où coexistent des facettes de grains d'apparence fragile, du clivage (transgranulaire), des interfaces carbures/matrice fragiles et des ligaments ductiles. Ce genre de complexité est hors de portée de cet article qui se focalise sur la physique d'une pointe de fissure idéale, intergranulaire, à l'échelle nanométrique. Deux mécanismes sont généralement invoqués: la décohésion ou la plasticité intense et confinée (HELP: "hydrogen enhanced localized plasticity"). Cet article est la fusion de deux papiers de conférence récents qui paraîtrons dans "Proceedings of the International Hydrogen Conference 2012, Jackson Lake, Wyoming, Ed. B. Somerday and P. Sofornis". L'un porte sur l'étude des mécanismes de décohésion (une revue critique des calculs ab initio et une étude de l'influence de clusters de lacune sur la rupture), l'autre sur l'effet de H sur l'émission de dislocations, directement depuis la pointe (le rôle des sources extérieures n'est pas considéré).
