Advanced abdominal pregnancy: challenges, update and review of current management
Authors: McDougall Anna , Morin Amelie , Kuzmich Tatsiana , Odejinmi Funlayo 
Published: May 2022

Key content
Although extremely rare, advanced abdominal pregnancy (AAP) is associated with considerable maternal and fetal morbidity and mortality. However, when diagnosed early and managed appropriately, it is possible to have successful outcomes.
There are no specific criteria to diagnose AAP and it may be missed on ultrasound. Magnetic resonance imaging is the gold standard for evaluating placental implantation and preoperative planning.
Management depends on the gestational age at diagnosis, with consideration of termination, preterm delivery and conservative management until further fetal maturation.
Multidisciplinary preoperative planning is paramount for optimal outcome. Delivery is recommended in a tertiary centre with access to interventional radiology.
Management of the placenta depends on the degree of penetration and the organ in which it embeds. Where the risk of removal increases the risk of maternal morbidity, it may be left in situ.
Learning objectives
To outline the classification of AAP.
To understand the diagnostic challenges and the role of imaging in preoperative assessment.
To describe the different management options and associated ethical issues.
Ethical issues
There is no established guidance for the diagnosis and management of AAP.
AAP requires careful evaluation when deciding whether to terminate the pregnancy or provide expectant management.
Informed consent requires acknowledgement of the considerable risks.

SUMMARYBean leaf crumple virus (BLCrV) is a novel begomovirus (family Geminiviridae, genus Begomovirus) infecting common bean (Phaseolus vulgaris L.), threatening bean production in Latin America. Genetic resistance is required to ensure yield stability and reduce the use of insecticides, yet the available resistance sources are limited. In this study, three common bean populations containing a total of 558 genotypes were evaluated in different yield and BLCrV resistance trials under natural infection in the field. A genome‐wide association study identified the locus BLC7.1 on chromosome Pv07 at 3.31 Mbp, explaining 8 to 16% of the phenotypic variation for BLCrV resistance. In comparison, whole‐genome regression models explained 51 to 78% of the variation and identified the same region on Pv07 to confer resistance. The most significantly associated markers were located within the gene model Phvul.007G040400, which encodes a leucine‐rich repeat receptor‐like kinase subfamily III member and is likely to be involved in the innate immune response against the virus. The allelic diversity within this gene revealed five different haplotype groups, one of which was significantly associated with BLCrV resistance. As the same genome region was previously reported to be associated with resistance against other geminiviruses affecting common bean, our study highlights the role of previous breeding efforts for virus resistance in the accumulation of positive alleles against newly emerging viruses. In addition, we provide novel diagnostic single‐nucleotide polymorphism markers for marker‐assisted selection to exploit BLC7.1 for breeding against geminivirus diseases in one of the most important food crops worldwide.
CT can identify characteristic features of hypaxial muscle abscesses in dogs due to presumed migrating vegetal foreign material as well as additional changes along the migratory tract in other anatomic regions

Published: May 2022

AbstractHypaxial muscle abscess is an important differential in dogs presenting for abdominal or back pain, lameness, and nonspecific signs like fever, lethargy, and hyporexia. It can occur concurrently with intrathoracic disease such as pyothorax secondary to migrating vegetal foreign material. Twelve dogs that underwent CT of the lumbar spine or abdomen and had a diagnosed hypaxial abscess on surgical and/or microbiological examination were included in this retrospective, descriptive case series. Computed tomography findings and findings from other imaging modalities employed were described. Eleven dogs were hunting breeds. Clinical signs included lethargy, fever, increased respiratory effort, and abdominal or back pain. Radiography and/or ultrasonography were employed during preliminary work up at clinician discretion and respectively revealed changes consistent with osteomyelitis in the cranial lumbar vertebrae and heterogenous, hypoechoic areas in the hypaxial musculature consistent with abscesses. Computed tomography findings included enlargement of hypaxial muscles with well‐defined fluid attenuating noncontrast enhancing areas with a contrast‐enhancing rim consistent with abscesses, periosteal reaction and lysis of vertebrae, and retroperitoneal effusion. Four of the 12 cases in this series had material identified and removed at surgery. The other eight cases were presumed to be the same disease process based on compatible signalment, imaging findings, and microbiological results. Migrating vegetal foreign bodies are a common problem at the authors’ institution. Computed tomography provided expedient, thorough visualization of the relevant hypaxial lesions for diagnostic and surgical planning purposes and also characterized intrathoracic components of this disease.
Unleashing the Power of Athlete Leadership Groups: Strategies Perceived to Leverage the Potential of Shared Leadership in Professional Football Teams
Authors: Haddad Gina , O’Connor Donna , Burns Kellie 
Published: May 2022

Coaches of professional sports teams frequently adopt athlete leadership groups in their quest to gain a competitive advantage. Although the benefits of shared leadership approaches are well established, the sharing of leadership with athletes is never straightforward with little in the way of guidelines to assist coaches with this process. The current study provides insight into the strategies perceived to leverage the strengths of this shared leadership approach in professional football teams. Semistructured interviews were conducted with 16 coaches and 14 athlete-leaders from 17 professional teams, across four football leagues. An inductive thematic analysis generated five high-order themes: (a) player-owned team values and behaviors linked to accountability, (b) player-driven values-based athlete leadership group selection, (c) authentic and appropriate empowerment, (d) strong intrateam relationships, and (e) expert facilitation and dedicated leadership development support. Results illustrate teams are more likely to realize the potential of athlete leadership groups when coaches pay careful attention to the preparedness, social identity-based group influence processes, expert facilitation, and ongoing leadership development support required for shared leadership. Findings suggest that establishing high levels of trust and progressively and authentically empowering athlete-leaders within clearly defined parameters based on a mutually agreed behavioral framework may mitigate risks commonly associated with player empowerment-based leadership models.

Published: May 2022

Background: Bone turnover markers can predict subsequent changes in bone status. This study aimed to investigate the relationship between usual daily physical activity (PA) with bone markers. Methods: This cross-sectional study was conducted on 500 postmenopausal women aged 50–65 years in Tabriz-Iran in 2018. The women were recruited by a simple random method. The International Physical Activity Questionnaire was used to assess PA. The laboratory tests of 25-Hydroxyvitamin D3, alkaline phosphatase, calcium, and phosphorus were also used to examine bone function. Results: The education, income, employment status, sun exposure, and history of exercise were significantly correlated with PA. Among reproductive characteristics, only menopausal age showed a significant relationship with total PA levels (r = .285, P = .048). None of the anthropometric indices showed a statistically significant relationship with total PA. Serum calcium (r = −.242) and phosphorus (r = −.045) levels showed negative and inverse relationships with total PA. The intensity of this association was statistically significant only for the calcium (β = −0.108, 95% confidence interval, −0.117 to 0.098; P = .023). 25-Hydroxyvitamin D3 (r = .007) and alkaline phosphatase (r = .046) were directly and positively but nonsignificantly correlated to the intensity of total PA. Conclusion: Usual daily physical activity with any levels has no effect on bone markers except for calcium. Despite of the beneficial effects of PA, our findings showed that usual daily physical activity without increasing total PA cannot affect bone health. For maximal effects of PA on bone health, it seems that a degree of intensity, continuity, and regularity of PA programs should be considered to stimulate bone formation.
Correlation between South China and India and development of double rift systems in the South China–India Duo during late Neoproterozoic time

Published: May 2022

AbstractSouth China, India, and their derivative blocks preserve many similar magmatic and sedimentary records related to the tectonic transition from Rodinia to Gondwana. They provide crucial insights into not only the paleogeographic correlation between them but also the geodynamic mechanism for such a transition. Our new results, combined with published data from these blocks, reveal that South China remained linked with India at least from ca. 830 Ma to ca. 510 Ma and formed the South China–India Duo, which is located at the western margin of Rodinia. The identical magmatism and sedimentation reflect that double late Neoproterozoic rift systems in the South China–India Duo developed owing to the rollback of subducting oceanic slab beneath them. For example, an intracontinental rift developed along the Jiangnan–Aravalli–Delhi fold belt, which separated the Yangtze-Marwar block from the Cathaysia-Bundelkhand block. Another intra-arc rift developed contemporaneously along the northern and western margins of the Yangtze block, through the Marwar terrane of western India, and then into the Seychelles and Madagascar terranes. Such an intra-arc rift is the most feasible explanation for the common development of coeval arclike and extension-related magmatic rocks and extensional sedimentary sequences on the western margin of the South China–India Duo, in Seychelles and Madagascar, and even at other subduction zones. South China was finally separated from Indian Gondwana at ca. 510 Ma due to the opening of the Proto-Tethys Ocean.
Permeability of subducted oceanic crust revealed by eclogite-facies vugs
Authors: Angiboust Samuel , Raimondo Tom 
Published: May 2022

Abstract
We report the finding of rare eclogite-facies vugs forming millimeter- to centimeter-sized pockets in meta-ophiolites from the western European Alps. Euhedral garnet crystals covering the vug walls display oscillatory chemical zoning for a wide range of major and trace elements, including Cr, Mn, and rare earth elements. Thermodynamic modeling revealed that closed-system fluid production through the breakdown of prograde glaucophane, lawsonite, and chlorite between 505 °C and 525 °C can successfully explain porosity creation of ~4% and the mineralogical properties of the vugs. Available geologic and geochronologic constraints indicate that the eclogitization of the downgoing mafic crust spanned a window of at least 1 m.y. These observations can only be explained by the presence of extremely low permeability values (&lt;10−22 m2) to keep the fluid confined at the meter scale within vugs on such time scales. Our field-based report of eclogite porosity provides the first in situ confirmation of previous experimental data and geophysical estimates on active margins. A substantial amount of fluid trapped in this porosity may be carried deeper than expected into Earth's mantle, with implications for volatile recycling budgets.
Mechanical characterization of Al7075 reinforced with borosilicate powder
Authors: Ayyandurai M. , Mohan B. 
Published: May 2022

Our study examined a novel composite material for marine applications. The matrix for the composite was aluminium alloy 7075 (Al7075), the properties of which include good durability, specific strength, and hardness. We investigated the mechanical properties and behaviour of the alloy matrix when combined with borosilicate powder as reinforcement. The composite was prepared by stir casting the Al7075 with specific weight percentages of nano-borosilicate. The performance of the composite was evaluated via analysis of the microstructure (SEM) and mechanical behaviour. The results from our Vickers microhardness tests showed that increasing the levels of nano-borosilicate from 2 to 8 volume percent increased the hardness of the composite.

supersymmetric Yang–Mills theory in terms of the component field of the Wess–Zumino gauge. We show that the flow-time derivative and supersymmetry transformation that is naively extended to 4+1 dimensions by replacing the four-dimensional fields with the corresponding flowed fields commute with each other up to a gauge transformation. In this sense, the obtained flow is supersymmetric in the Wess–Zumino gauge. We also discuss more about the symmetry of the flow equation.
Kaniadakis holographic dark energy and cosmology
Authors: Drepanou Niki , Lymperis Andreas , Saridakis Emmanuel N. , Yesmakhanova Kuralay 
Published: May 2022

AbstractWe construct a holographic dark energy scenario based on Kaniadakis entropy, which is a generalization of Boltzmann-Gibbs entropy that arises from relativistic statistical theory and is characterized by a single parameter K which quantifies the deviations from standard expressions, and we use the future event horizon as the Infrared cutoff. We extract the differential equation that determines the evolution of the effective dark energy density parameter, and we provide analytical expressions for the corresponding equation-of-state and deceleration parameters. We show that the universe exhibits the standard thermal history, with the sequence of matter and dark-energy eras, while the transition to acceleration takes place at $$z\approx 0.6$$

. Concerning the dark-energy equation-of-state parameter we show that it can have a rich behavior, being quintessence-like, phantom-like, or experience the phantom-divide crossing in the past or in the future. Finally, in the far future dark energy dominates completely, and the asymptotic value of its equation of state depends on the values of the two model parameters.

Published: May 2022

For a partition [Formula: see text] of [Formula: see text], let [Formula: see text] be the ideal of [Formula: see text] generated by all Specht polynomials of shape [Formula: see text]. We assume that [Formula: see text]. Then [Formula: see text] is Gorenstein, and [Formula: see text] is a Cohen–Macaulay ring with a linear free resolution. In this paper, we construct minimal free resolutions of these rings. Zamaere et al. [Jack polynomials as fractional quantum Hall states and the Betti numbers of the [Formula: see text]-equals ideal, Commun. Math. Phys. 330 (2014) 415–434] already studied minimal free resolutions of [Formula: see text], which are also Cohen–Macaulay, using highly advanced technique of the representation theory. However, we only use the basic theory of Specht modules, and explicitly describe the differential maps.
SpectraTr: A novel deep learning model for qualitative analysis of drug spectroscopy based on transformer structure
Authors: Fu Pengyou , Wen Yue , Zhang Yuke , Li Lingqiao , Feng Yanchun , Yin Lihui , Yang Huihua 
Published: May 2022

The drug supervision methods based on near-infrared spectroscopy analysis are heavily dependent on the chemometrics model which characterizes the relationship between spectral data and drug categories. The preliminary application of convolution neural network in spectral analysis demonstrates excellent end-to-end prediction ability, but it is sensitive to the hyper-parameters of the network. The transformer is a deep-learning model based on self-attention mechanism that compares convolutional neural networks (CNNs) in predictive performance and has an easy-to-design model structure. Hence, a novel calibration model named SpectraTr, based on the transformer structure, is proposed and used for the qualitative analysis of drug spectrum. The experimental results of seven classes of drug and 18 classes of drug show that the proposed SpectraTr model can automatically extract features from a huge number of spectra, is not dependent on pre-processing algorithms, and is insensitive to model hyperparameters. When the ratio of the training set to test set is 8:2, the prediction accuracy of the SpectraTr model reaches 100% and 99.52%, respectively, which outperforms PLS_DA, SVM, SAE, and CNN. The model is also tested on a public drug data set, and achieved classification accuracy of 96.97% without pre-processing algorithm, which is 34.85%, 28.28%, 5.05%, and 2.73% higher than PLS_DA, SVM, SAE, and CNN, respectively. The research shows that the SpectraTr model performs exceptionally well in spectral analysis and is expected to be a novel deep calibration model after Autoencoder networks (AEs) and CNN.

Adjacent vertex-distinguishing proper edge-coloring is the minimum number of colors required for the proper edge-coloring of [Formula: see text] in which no two adjacent vertices are incident to edges colored with the same set of colors. The minimum number of colors required for an adjacent vertex-distinguishing proper edge-coloring of [Formula: see text] is called the adjacent vertex-distinguishing proper edge-chromatic index. Adjacent vertex-distinguishing proper edge-chromatic indices of the middle graph, splitting graph and shadow graph of path and cycle are determined. Adjacent vertex-distinguishing proper edge-chromatic indices of the triangular grid [Formula: see text], [Formula: see text]-graph and generalized [Formula: see text]-graph are also determined.
