Authors: Akila Dr. M. , Mouleswaran T.S , Pradeep P , Prasanna R 
Published: July 2021

Abstract
Early diagnosis of bearing failures can save time, effort, and money on rotating machine maintenance. On this test, a non-touch type vibration pickup was designed and refined to capture vibration data for bearing fitness tracking under tight load and pace variations, avoiding the bodily connection of vibration pickup to the system tool. The signal was denoised and fault analysis was performed using a Hilbert rework. Principal Component Analysis (PCA) was used to reduce the dimensionality of the extracted capabilities, and then the chosen capabilities for lowering the amount of enter capabilities and discovering the maximum premier function set, the Sequential Floating Forward Selection (SFFS) method was used to rank them in order of significance. Finally, Support Vector Machines (SVM) and Artificial Neural Networks (ANN) were used to determine and classify the numerous faults in bearings. A comparison of SVM and ANN efficacy was carried out. The results reveal that vibration signatures from advanced non-touch sensors (NCS) correspond well with accelerometer data collected under the same conditions. The classification accuracy obtained by combining the advanced NCS with various sensors mentioned in the literature is comparable to that obtained by using the advanced NCS alone. The proposed method could be utilised to detect automated popularity system faults and issue early warnings, preventing unwelcome and unplanned device shutdowns due to bearing failure.

Abstract
To improve the mechanical properties of polyaspartate polyurea (PAEP), functionalized multi-walled carbon nanotubes reinforced polyurea composites (HDIT-MWCNTs/PAEP) were prepared by covalently functionalizing multi-walled carbon nanotubes (MWCNTs) with hexamethylene diisocyanate (HDI) trimer. The dispersibility, wettability and interfacial properties of HDI trimer functionalized MWCNTs (HDIT-MWCNTs) in PAEP were analyzed. The tensile properties of HDIT-MWCNTs/PAEP composites were tested and the reinforcement mechanism revealed. The results showed that compared with the pure multi-walled carbon nanotubes (P-MWCNTs), HDIT-MWCNTs were uniformly dispersed in the matrix and the wettability and interfacial properties were greatly improved. The contact angle of PAEP with HDIT-MWCNTs was 32.92°, a reduction of 46.3% compared with the P-MWCNTs. The interfacial energy and adhesion work between PAEP and HDIT-MWCNTs (25.14 mJ m−2, 95.47 mJ m−2) were 46.7% and 24.2% higher than those of P-MWCNTs. When the content of HDIT-MWCNTs was 0.5 phr, the tensile strength and Young’s modulus of the composites reached a maximum of 17.78 MPa and 170.31 MPa; an increase of 28.4% and 90.8% respectively, compared with pure PAEP. According to the cross-section of HDIT-MWCNTs/PAEP, its strengthening mechanism was mainly manifested by the deflection and bifurcation of cracks and the plastic deformation of PAEP matrix due to HDIT-MWCNTs pulling out from the matrix.
Three-dimensional kinematics of euchelicerate limbs uncover functional specialization in eurypterid appendages
Authors: Bicknell Russell D C , Melzer Roland R , Schmidt Michel 
Published: July 2021

AbstractSea scorpions (Euchelicerata: Eurypterida) explored extreme limits of the aquatic euchelicerate body plan, such that the group contains the largest known marine euarthropods. Inferences on eurypterid life modes, in particular walking and eating, are commonly made by comparing the group with horseshoe crabs (Euchelicerata: Xiphosura). However, no models have been presented to test these hypotheses. Here, we reconstruct prosomal appendages of two exceptionally well-preserved eurypterids, Eurypterus tetragonophthalmus and Pentecopterus decorahensis, and model the flexure and extension of these appendages kinematically in three dimensions (3D). We compare these models with 3D kinematic models of Limulus polyphemus prosomal appendages. This comparison highlights that the examined eurypterid prosomal appendages could not have moved prey items effectively to the gnathal edges and would therefore not have emulated the motion of an L. polyphemus walking leg. It seems that these eurypterid appendages were used primarily to walk or grab prey, and other appendages would have moved prey for mastication. Such 3D kinematic modelling highlights how eurypterid appendage morphologies placed substantial limits on their function, suggesting a high degree of specialization, especially when compared with horseshoe crabs. Such three-dimensional kinematic modelling of these extinct groups therefore presents an innovative approach to understanding the position of these animals within their respective palaeoecosystems.

AbstractThe pomace of sea buckthorn berries is usually discarded when transforming into nonalcoholic or alcoholic beverages, jellies, jams, juices, candies and dairy products. Here, we established a promising approach for one step separation of five flavonoids from the waste pomace of sea buckthorn berries through counter-current chromatography. The crude extract of waste pomace of sea buckthorn berries after juicing was injected into counter-current chromatography with hexane/ethyl acetate/ethanol/water (v/v/v/v, 5:7:5:7) as the solvent system. As a result, five flavonoids, including quercetin, laricitrin, isorhamnetin-7-O-rhamnoside, kaempferol and isorhamnetin, were obtained in a single step separation. Our finding showed that ethanol is a good substitute for methanol to regulate the partition coefficient in hexane/ethyl acetate/ methanol/water system. This study provided a significant measure to utilize the waste pomace of Sea buckthorn berries.
“What’s Real?”: Digital Technology and Negative Affect in Jennifer Egan’sLook at MeandThe Keep
Authors: Horton Emily 
Published: July 2021

AbstractThis article investigates the relationship between affect, digital technology, and neoliberalism in Jennifer Egan’s second and third novels: Look at Me (2001) and The Keep (2006). I argue that this relationship is central to Egan’s politicized (post-postmodern) understanding of the contemporary subject, whose feeling is overtly conditioned by the new media culture and technology as well as by the aspirational and elitist orientation of neoliberal discourse. Emphasizing these texts’ engagement with negative affects, including “cruel optimism” and shame, which dominate their narrative focalizations, I nevertheless consider how these feelings remain open to transformation in these novels, particularly in moments of critique, creativity, and interpersonal care.
Reconstructing landscapes of ungulate parturition and predation using vegetation phenology

Published: July 2021

AbstractEnhanced vegetation index (EVI) data can be used to identify and define the space in which ungulates practice parturition and encounter predation. This study explores the use of EVI data to identify landscapes linked to ungulate parturition and predation events across space, time, and environmental conditions. As a case study, we used the moose population (Alces alces) of northern Minnesota in the USA. Using remotely sensed EVI data rasters and global positioning system collar data, we quantified how vegetation phenology and moose movement shaped the births and predation of 52 moose calves from 2013 to 2020 on or adjacent to the Grand Portage Indian Reservation. The known sources of predation were American black bears (Ursus americanus, n = 22) and gray wolves (Canis lupus, n = 28). Satellite-derived data summarizing seasonal landscape features at the local level revealed that landscape heterogeneity use by moose can help to quantitatively identify landscapes of parturition and predation in space and time across large areas. Vegetation phenology proved to be differentiable between adult moose ranges, sites of cow parturition, and sites of calf predation. Landscape characteristics of each moose group were consistent and tractable based on environment, suggesting that sites of parturition and predation of moose are predictable in space and time. It is possible that moose selected specific landscapes for parturition despite risk of increased predation of their calves, which could be an example of an "ecological trap." This analytical framework can be employed to identify areas for future ungulate research on the impacts of landscape on parturition and predation dynamics.

Abstract
Hematological parameters can provide key information to an animal health status. However, this information is usually hard to obtain. Here, we described the hematological parameters of Leptodactylus podicipinus in the Brazilian Pantanal. We measured red blood cell morphometrics, erythrogram, and leukogram. We also tested for phylogenetic signal in the erythrogram and leukogram of 48 frog species from 15 families, testing if body size explains their variation. Lymphocytes were the most abundant leukocytes (&gt;60%) in L. podicipinus, followed by neutrophils (∼10%). Given that L. podicipinus is an abundant and widely distributed species in central Brazil, knowing its hematological pattern can help establish a baseline and improve its use as a bioindicator of environmental degradation. Mean corpuscular hemoglobin and value contributed more to the phylomorphospace of erythrogram, in which Leptodactylus spp. and Hypsiboas raniceps had lower values of these variables, whereas Bufotes viridis and Hyla arborea had high values. The phylogenetic signal was spread throughout the dimensions of the leukogram phylomorphospace. The variables that most contributed to it were total leukocytes counts, lymphocytes, and neutrophils. We also found a moderate phylogenetic signal for both the erythrogram and leukogram. Accordingly, body size accounted for a low proportion of variation in both the leukogram (4.7%) and erythrogram (0.57%). By applying phylogenetic comparative methods to hematological parameters, our results add a new perspective on the evolution of blood cell physiology in frogs.
Successful interdisciplinary treatment of a rare cause of acute myocardial ischaemia from intermittent tumour-associated obstruction of the left main coronary artery: a case report
Authors: Huenges Katharina , Hartmann Franz , Panholzer Bernd , Puehler Thomas 
Published: July 2021

Abstract

Background
A papillary fibroelastoma of the aortic valve has been reported as a rare cause of myocardial ischaemia. An advanced combined interventional and surgical approach leading to sufficient therapy for the patient is presented in this case report.

Case summary
A 56-year-old female patient presented in an emergency room of a hospital with an acute coronary syndrome. Over 1.5 years, recurrent stable angina had been known in the patient and significant coronary artery disease has already been ruled out in a previous coronary angiogram. The patient was immediately transferred to the catheter laboratory due to cardiogenic shock where a drug-eluting stent was implanted to, firstly, recanalize the left main coronary artery (LMCA) and, secondly, to protect the left main ostium from obstruction by an echocardiographic-proven mass. During subsequent deterioration of haemodynamics caused by decreasing left ventricular function and acute severe mitral insufficiency, firstly an intra-aortic balloon pump and secondly a veno-arterial extracorporeal membrane oxygenation was established through the femoral vessels. The patient was transferred to our cardiac surgery unit and was successfully operated utilizing a valve-sparing technique by extracting the tumour mass from the left coronary cusp and extracting the stent carefully from the LMCA. Histology revealed a papillary fibroelastoma.

Conclusion
A papillary fibroelastoma of the aortic valve with intermittent obstruction of the coronary arteries requires surgical therapy. Interventional recanalization and extracorporeal support might be useful strategies to ensure the patient’s safety as a bridge to surgery.
The first complete genome sequence of species Shewanella decolorationis, from a bioremediation competent strain Ni1-3
Authors: Wang Yicheng , Cai Xunchao , Mao Yanping 
Published: July 2021

Abstract
Shewanella decolorationis are Gram-negative γ-Proteobacteria with environmental bioremediation potential because they can perform anaerobic respiration using various types of pollutants as terminal electron acceptors. So far, three isolated and cultured strains of S. decolorationis have been reported. However, no complete S. decolorationis genome has been published yet, which limited exploring their metabolism and feasibility in application. Here, S. decolorationis Ni1-3 isolated from an electroplating wastewater treatment plant showed strong reduction capabilities on azo dyes and oxidized metals. In order to construct the complete genome, high-quality whole-genome sequencing of strain Ni1-3 were performed by using both Nanopore MinION and Illumina NovaSeq platforms, from which the first complete genome of S. decolorationis was obtained by hybrid assembly. The genome of strain Ni1-3 contains a megaplasmid and a circular chromosome which encodes more proteins than that of the strains LDS1 and S12 belonging to the same species. In addition, more Clustered Regularly Interspaced Short Palindromic Repeats (CRISPRs) are identified in strain Ni1-3 genome. Importantly, 32 cytochrome-c and AzoR azoreductase coding genes are identified in the genome, which make strain Ni1-3 competent to degrade the azo dyes and versatile to bioremediate some other environmental pollution. The complete genome sequence of strain Ni1-3 can expand our knowledge toward its metabolic capabilities and potential, meanwhile, provide a reference to reassemble genomes of other S. decolorationis strains.

AbstractLet $\mathcal{M}$ be a small $n$-abelian category. We show that the category of finitely presented functors ${\operatorname{mod}}$-$\mathcal{M}$ modulo the subcategory of effaceable functors ${\operatorname{mod}}_0$-$\mathcal{M}$ has an $n$-cluster tilting subcategory, which is equivalent to $\mathcal{M}$. This gives a higher-dimensional version of Auslander’s formula.
Poetry and the Possibility of Paraphrase
Authors: Currie Gregory , Frascaroli Jacopo 
Published: July 2021

AbstractWhy is there a long-standing debate about paraphrase in poetry? Everyone agrees that paraphrase can be useful; everyone agrees that paraphrase is no substitute for the poem itself. What is there to disagree about? Perhaps this: whether paraphrase can specify everything that counts as a contribution to the meaning of a poem. There are, we say, two ways to take the question; on one way of taking it, the answer is that paraphrase cannot. Does this entail that there is meaning mysteriously locked in a poem, meaning that cannot be represented in any way other than via the poem itself? If that were so it would have profound implications for poetry’s capacity to convey insight. We suggest reasons for thinking that the entailment does not hold. Throughout, we connect the traditional debate over paraphrase, which has largely been conducted within the fields of philosophy and literary theory, with recent empirically oriented thinking about the communicability of meaning, represented by work in pragmatics. We end with a suggestion about what is to count as belonging to meaning, and what as merely among the things that determine meaning.

What drives financial development? A Meta-regression analysis
Authors: Doucouliagos Chris , de Haan Jakob , Sturm Jan-Egbert 
Published: July 2021

Abstract
This article offers a meta-regression analysis of the literature on the drivers of financial development (FD). Our results based on 1,900 estimates suggest that institutional quality is positively correlated to both private sector credit and stock market capitalization (both as share of Gross Domestic Product). Domestic financial openness has a positive effect on both proxies for FD, while trade openness seems only important for stock market capitalization. Inflation has an adverse effect on FD, which is larger for stock market capitalization. Finally, we conclude that the literature has not yet robustly established that remittances matter for FD.
Jet collision with accreting tori around SMBHs GRHD and light surface constraints in aggregates of misaligned tori
Authors: Pugliese Daniela , Stuchlík Zdenek 
Published: July 2021

Abstract
We explore the possibility of jet collisions with accreting tori orbiting around super-massive black holes. The analysis provides constraints on the formation and the observational evidence of the host configurations. We use a General Relativistic Hydrodynamic model, investigating the light surface contraints in aggregates of misaligned tori orbiting a central static Schwarzschild black hole. Each (toroidal) configuration of the agglomeration is a geometrically thick, pressure-supported, perfect fluid torus. Aggregates include proto-jets, the open cusped solutions associated with the geometrically thick tori. Collision emergence and the stability properties of the aggregates are considered at different inclination angles relative to a fixed distant observer. We relate the constraints to the relevant frequencies of the configurations and fluid specific angular momentum, separating the constraints related to the fluid hydrodynamics and those related to the geometric backgrounds. We analyze the existence of accreting tori supporting jet-emission. We discuss the existence of orbit-replicas that could host shadowing effects in replicas of the emissions in two regions; close to and far from the BH (horizon replicas in jet shells). Our investigation clarifies the role of the pressure gradients of the orbiting matter and the essential role of the radial gradient of the pressure in the determination of the disk verticality. Finally, we analyze the possibility that a toroidal magnetic field could be related to the collimation of proto-jets.
Epigenetics and Postsurgical Pain: A Scoping Review
Authors: López-Muñoz Eunice , Mejía-Terrazas Gabriel Enrique 
Published: July 2021

Abstract

Objective
Multiple factors are involved in the physiology and variability of postsurgical pain, a great part of which can be explained by genetic and environmental factors and their interaction. Epigenetics refers to the mechanism by which the environment alters the stability and expression of genes. We conducted a scoping review to examine the available evidence in both animal models and clinical studies on epigenetic mechanisms involved in the regulation of postsurgical and chronic postsurgical pain.

Methods
The Arksey and O’Malley framework and the PRISMA-ScR (Preferred Reporting Items for Systematic Review and Meta-Analysis, scoping reviews extension) guidelines were used. The PubMed, Web of Science, and Google Scholar databases were searched, and the original articles cited in reviews located through the search were also reviewed. English-language articles without time limits were retrieved. Articles were selected if the abstract addressed information on the epigenetic or epigenomic mechanisms, histone, or DNA methylation and microribonucleic acids involved in postsurgical and chronic postsurgical pain in animal models and clinical studies.

Results
The initial search provided 174 articles, and 95 were used. The available studies to date, mostly in animal models, have shown that epigenetics contributes to the regulation of gene expression in the pathways involved in postsurgical pain and in maintaining long-term pain.

Conclusion
Research on possible epigenetic mechanisms involved in postsurgical pain and chronic postsurgical pain in humans is scarce. In view of the evidence available in animal models, there is a need to evaluate epigenetic pain mechanisms in the context of human and clinical studies.

Abstract
Brassica cover crops are an option for producers to incorporate into their cropping system to improve soil health and also provide a feed resource for cattle. While brassica cover crops have been widely used for grazing cows, their use as a backgrounding feedstuff is relatively unknown. The objective of this study was to determine the impact of feeding a brassica cover crop mixture during backgrounding on live animal performance and carcass characteristics. A total of 30 Angus-based steers were assigned to one of two dietary treatments during backgrounding 1) ad libitum access to a diet containing freshly cut brassica cover crop forage (CC) containing radish, turnip, rapeseed, rye grass, and a liquid supplement or 2) common Midwestern dry lot growing diet containing silage, soybean meal, grass hay, and a liquid supplement (CON). Steers were assigned to electronic feed bunks (Insentec RIC, Hokofarm Group; Marknesse, the Netherlands) for collection of individual feed intake. Diets were formulated to be nutritionally similar on a dry matter basis. Steers were paired by weight across treatments and pair fed. Dry matter intake (DMI) was calculated daily for steers in the CC treatment and the following day, CON steers were allowed access to an equal amount of dry matter using the Insentec RIC system. Steers were weighed weekly and backgrounded for 44 days before transitioning to a common finishing diet and weighed every 28 days. Steers were harvested at an estimated average backfat thickness of 1 cm. Standard carcass data were measured and strip loins and shoulder clods were collected. Instrumental and subjective color were measured on ground beef for 8 days and instrumental color was measured on strip steaks for 11 days. Treatment did not influence carcass characteristics, average daily gain, and DMI (P &gt; 0.17). However, CON steers exhibited increased gain to feed ratio (P = 0.02). Additionally, a treatment by day interaction was observed for ground beef discoloration as the CC treatment displayed increased discoloration on days 4, 6, and 7 of case life (P &lt; 0.01). These data indicate that brassicas may be utilized in a backgrounding diet without negatively impacting carcass characteristics but may decrease case life of ground beef.
