Published: October 2021

Abstract
Electrolytic Ni–Re alloy coatings were obtained in galvanostatic conditions from nickel–rhenium baths with different contents of ammonium rhenate(vii) (0.5, 1.25, 2.5 and 5 g·L−1). The surface morphology, chemical, and phase composition of the obtained materials were determined. The coatings’ corrosion resistance tests were carried out in a 5% NaCl solution. Based on the tests, it was found that the highest corrosion resistance characterizes the coating with the highest rhenium content (37%). This material can be recommended for practical use as a protective coating. The density of the deposited Ni–37Re alloy was determined, and its specific surface area was assessed. The melting point, hardness, and electrical conductivity were also determined.

Published: October 2021

AbstractConsiderable attention has been given to graphene as a reinforcement material for metal matrix composite (MMC) because of its great potential for use in the automotive and aerospace industry. In general, the difficulty in achieving optimally improved properties can be attributed to poor wettability, agglomerations, and non-uniform distribution of reinforcement in the MMCs. Therefore, in terms of structural integrity, interfacial bonding, and its strengthening mechanism are important to achieve a high performance composite, which makes it imperative to discuss the integration of graphene into the alloy. The reinforcement mechanism of graphene-reinforced aluminium alloy has been evaluated in a limited number of studies, and this article examines current publications in this area. This article outlines three key topics related to the key challenges of graphene as a reinforcement material, the strengthening mechanism of graphene in a metal matrix, and the factors limiting the properties enhancement. Lastly, future works and recommendations addressed are summarized. The review presented aims to benefit to a wide range of industries and researchers and serve as a resource for future scholars.
Effect of scan speed on grain and microstructural morphology for laser additive manufacturing of 304 stainless steel
Authors: Chai Rongxia , Zhang Yapu , Zhong Bin , Zhang Chuanwei 
Published: October 2021

Abstract
The laser scanning parameters used in laser additive manufacturing (LAM) can impact the growth direction of the columnar grains produced during rapid solidification. This growth direction affects the mechanical properties of the manufactured parts after cladding. The effective use of a high laser power and a rapid scanning speed for LAM requires an accurate analysis of the relationships between the laser scanning process parameters and the grain growth direction and microstructural morphology of the scanned material. An experimental study was conducted to determine the macromorphology, microstructural morphology, and grain growth direction of 304 stainless steel material obtained during the laser scanning process at different scan speeds. The impact of the scan speed on different regions in the cladding layer (the clad zone (CZ), the heat affected zone (HAZ), and the dilution zone (DZ)) was determined, as well as on the direction of grain growth, the grain morphology and the grain size (which are the microstructures of the cladded materials), the degree of elemental mixing during laser scanning (which are changes in material composition of cladded material), and the microscopic hardness of the CZ (which is one of the mechanical properties of cladded material). With increasing scan speed, the CZ, HAZ, DZ, and dilution rate (DR) of the material gradually decreased, and grain growth gradually oriented towards the building direction of the cladding layer. At a 16 mm·s−1 scan speed, the angle between the grain growth direction and the scan direction was 84°. Changing the scan speed from 4 to 16 mm·s−1 caused the columnar grain size to gradually decrease from 13.3 to 9.2 μm and the corresponding microhardness to gradually increase.
Reframing Arabic narratives on Daesh [ISIS] textually through translation: MEMRI’s translation as a case study
Authors: Hijjo Nael F. M. , Almanna Ali 
Published: October 2021

Abstract
Many an ethically minded translator would think twice or thrice prior to translating an ideologically loaded text as they need to reflect the encoded ideologies of the original narrative in the target narrative. Yet, some translators decide, for different reasons, to undermine and challenge the narratives in question, thus applying various reframing strategies to superimpose certain directionality on the original narratives. This paper, therefore, examines the English translations of the Arabic editorials on Daesh (ISIS), published by the Washington-based Middle East Media Research Institute (MEMRI) that has a large impact on the US policy and the public. In this paper, we explain how media translation contributes to (re)framing the current civil war in Syria on the one hand, and how this promotes the narrative of ‘Arab and Muslim terrorists’ on the other. The study finds that by relying on the narrativity feature of selective appropriation, MEMRI extensively employs the textual reframing tools, i.e., addition and omission, thus promoting different narratives of the civil war. We propose that rival narratives could be circulated through translation where the translators reframe the original narratives and reconstruct the embedded narrativity features that, in turn, renegotiate the original arguments.

Nescient helix-loop-helix 2 (NHLH2) is a hypothalamic transcription factor that controls the expression of prohormone convertase 1/3, therefore having an impact on the processing of proopiomelanocortin and thus on energy homeostasis. Studies have shown that KO ofNhlh2results in increased body mass, reduced physical activity, and hypogonadism. In humans, a polymorphism of theNHLH2gene is associated with obesity; and in Prader–Willi syndrome, a condition characterized by obesity, hypogonadism and behavioral abnormalities, the expression of NHLH2 is reduced. Despite clinical and experimental evidence suggesting that NHLH2 could be a good target for the treatment of obesity, no previous study has evaluated the impact of NHLH2 overexpression in obesity. Here, in mice fed a high-fat diet introduced right after the arcuate nucleus intracerebroventricular injection of a lentivirus that promoted 40% increase in NHLH2, there was prevention of the development of obesity by a mechanism dependent on the reduction of caloric intake. When hypothalamic overexpression of NHLH2 was induced in previously obese mice, the beneficial impact on obesity-associated phenotype was even greater; thus, there was an 80% attenuation in body mass gain, reduced whole-body adiposity, increased brown adipose tissue temperature, reduced hypothalamic inflammation, and reduced liver steatosis. In this setting, the beneficial impact of hypothalamic overexpression of NHLH2 was a result of combined effects on caloric intake, energy expenditure, and physical activity. Moreover, the hypothalamic overexpression of NHLH2 reduced obesity-associated anxiety/depression behavior. Thus, we provide an experimental proof of concept supporting that hypothalamic NHLH2 is a good target for the treatment of obesity.SIGNIFICANCE STATEMENTObesity is a highly prevalent medical condition that lacks an effective treatment. The main advance provided by this study is the demonstration of the beneficial metabolic and behavioral outcomes resulting from the overexpression of NHLH2 in the hypothalamus. When NHLH2 was overexpressed simultaneously with the introduction of a high-fat diet, there was prevention of obesity by a mechanism dependent on reduced caloric intake. Conversely, when NHLH2 was overexpressed in previously obese mice, there was reduction of the obese phenotype because of a combination of reduced caloric intake, increased physical activity, and increased thermogenesis. In addition, the overexpression of NHLH2 reduced anxiety/depression-like behavior. Thus, NHLH2 emerges as a potential target for the combined treatment of obesity and its associated anxiety/depression-like behavior.

Multiply-innervated muscle fibers (MIFs) are peculiar to the extraocular muscles as they are non-twitch but produce a slow build up in tension on repetitive stimulation. The motoneurons innervating MIFs establish en grappe terminals along the entire length of the fiber, instead of the typical en plaque terminals that singly-innervated muscle fibers (SIFs) motoneurons establish around the muscle belly. MIF motoneurons have been proposed to participate only in gaze holding and slow eye movements. We aimed to discern the function of MIF motoneurons by recording medial rectus motoneurons of the oculomotor nucleus. Single-unit recordings in awake cats demonstrated that electrophysiologically-identified medial rectus MIF motoneurons participated in different types of eye movements, including fixations, rapid eye movements or saccades, convergences, and the slow and fast phases of the vestibulo-ocular nystagmus, the same as SIF motoneurons did. However, MIF medial rectus motoneurons presented lower firing frequencies, were recruited earlier and showed lower eye position (EP) and eye velocity (EV) sensitivities than SIF motoneurons. MIF medial rectus motoneurons were also smaller, had longer antidromic latencies and a lower synaptic coverage than SIF motoneurons. Peristimulus time histograms (PSTHs) revealed that electrical stimulation to the myotendinous junction, where palisade endings are located, did not recurrently affect the firing probability of medial rectus motoneurons. Therefore, we conclude there is no division of labor between MIF and SIF motoneurons based on the type of eye movement they subserve.SIGNIFICANCE STATEMENTIn addition to the common singly-innervated muscle fiber (SIF), extraocular muscles also contain multiply-innervated muscle fibers (MIFs), which are non-twitch and slow in contraction. MIF motoneurons have been proposed to participate only in gaze holding and slow eye movements. In the present work, by single-unit extracellular recordings in awake cats, we demonstrate, however, that both SIF and MIF motoneurons, electrophysiologically-identified, participate in the different types of eye movements. However, MIF motoneurons showed lower firing rates (FRs), recruitment thresholds, and eye-related sensitivities, and could thus contribute to the fine adjustment of eye movements. Electrical stimulation of the myotendinous junction activates antidromically MIF motoneurons but neither MIF nor SIF motoneurons receive a synaptic reafferentation that modifies their discharge probability.

Published: October 2021

AbstractInhibitory GABAergic interneurons migrate over long distances from their extracortical origin into the developing cortex. In humans, this process is uniquely slow and prolonged, and it is unclear whether guidance cues unique to humans govern the various phases of this complex developmental process. Here, we use fused cerebral organoids to identify key roles of neurotransmitter signaling pathways in guiding the migratory behavior of human cortical interneurons. We use scRNAseq to reveal expression of GABA, glutamate, glycine, and serotonin receptors along distinct maturation trajectories across interneuron migration. We develop an image analysis software package, TrackPal, to simultaneously assess 48 parameters for entire migration tracks of individual cells. By chemical screening, we show that different modes of interneuron migration depend on distinct neurotransmitter signaling pathways, linking transcriptional maturation of interneurons with their migratory behavior. Altogether, our study provides a comprehensive quantitative analysis of human interneuron migration and its functional modulation by neurotransmitter signaling.

Published: October 2021

BACKGROUND AND OBJECTIVES
Rates of chlamydia and gonorrhea among adolescents continue to rise. We aimed to evaluate if a universal testing program for chlamydia and gonorrhea improved testing rates in an urban general pediatric clinic and an urban family medicine clinic within a system of federally qualified health care centers and evaluated the feasibility, cost, and logistic challenges of expanding implementation across 28 primary care clinics within a federally qualified health care centers system.

METHODS
A universal testing quality improvement program for male and female patient 14 to 18 years old was implemented in a general pediatrics and family medicine clinic in Denver, Colorado. The intervention was evaluated by using a controlled pre-post quasi-experimental design. The difference in testing rates due to the intervention was assessed by using a difference-in-differences regression model weighted with the inverse probability of treatment.

RESULTS
In total, 15 541 pediatric encounters and 5420 family medicine encounters were included in the analyses. In pediatrics, the unadjusted testing rates increased from 32.0% to 66.7% in the intervention group and from 20.9% to 28.9% in the comparison group. For family medicine, the rates increased from 38.5% to 49.9% in the intervention group and decreased from 26.3% to 24.8% in the comparison group. The intervention resulted in an adjusted increase in screening rates of 25.2% (P &lt; .01) in pediatrics and 11.8% (P &lt; .01) in family medicine. The intervention was well received and cost neutral to the clinic.

CONCLUSIONS
Universal testing for chlamydia and gonorrhea in primary care pediatrics and family medicine is a feasible approach to improving testing rates .

Authors: Botts Moritz Martin 
Published: October 2021

Purpose: Based on the various streams of distance literature in management, a framework is provided to make discourses on distance clear.
Design / Method / Approach: After a review of the most relevant distance concepts, a typology with five categories is introduced, which are then applied to the most relevant distance concepts in management.
Findings: A clear typology helps to clearly define and differentiate the various streams of distance literature.
Theoretical Implications: With the conceptual categories ‘topic’, ‘dimensionality’, and ‘level of analysis’, and the empirical categories ‘variables’ and ‘distance calculation’, distance concepts become more consistent.
Practical Implications: With a terminology for the different aspects of distance, practitioners can focus more clearly on specific remedies to bridge distance.
Originality / Value: The paper offers a new typology of different elements of distance.
Research Limitations / Future Research: The introduced typology will aid in the discussion of distance in management.
