Abstract
The article is devoted to the study of low-grade phosphorites of the Synycheno-Yaremivske deposit in the Iziumskyi district of the Kharkiv region. The possibility of enrichment of this ore by three methods is considered: mechanical, thermal and chemical, carried out in laboratory conditions. The qualitative and quantitative composition of phosphorite has been determined using X-ray fluorescence analysis and electron microscopy with an attachment for energy dispersive analysis. Both natural and enriched raw materials have been studied. Based on the data obtained, it is possible to concentrate this ore with a subsequent increase in the P2O5 content, despite the abnormally large amount of iron.

Published: January 2022

Abstract
Mining power complexes can significantly reduce the cost of production of mining enterprises and increase their competitive position in the relevant market. To solve the urgent problem of further improving the operation of mine energy complexes, it is proposed to include in their composition installations for the useful use of energy from low-potential sources with a freon-steam turbine, which implement the thermodynamic Rankine cycle. The article considers the features of the organization of the Rankine cycle depending on the properties of freons. When choosing freons, the emphasis is placed on the use of strictly ozone-safe freons that meet modern requirements for normalizing the value of the global warming potential. The previously proposed method for calculating the thermodynamic parameters necessary for evaluating useful action’s coefficient of using specific freons in a useful energy recovery equipment has been improved. The calculation of the energy efficiency of the equipment with a freon-steam turbine for the selected options for the use of freons is performed. The analysis of the obtained results showed that the use of ozone-safe freons with low values of the global warming potential in installations for the utilization of energy from low-potential sources will improve the operation of mine energy complexes.

Abstract
The underground construction is based on effective and rapid building of running tunnels that connect stations. The most effective technique of building is shield-driven tunneling. It is based on the application of a tunneling shield, it means, a special aggregate that excavates the ground and builds support. Even with the fact that it holds a surrounding massif, in the weak and layered rocks it is possible the formation of subsidence trough, namely, significant deformations of the daylight area. The solution of this geomechanical problem is possible on the basis of the parametric analysis of the supported circular working interacting with a layered massif. The results of the parametric analysis allow to predict deformation in the “tunneling shield – support of tunnel – surrounding massif” system. For the parametric analysis, the authors use a numerical method of finite elements based on the complex Structure Computer-Aided Design. The calculations of six supported workings with a variation of the properties of a layered massif are carried out. The results of the stress-strain state allow introducing the matrix of parameters into the prediction calculations, enabling quickly and effectively analyze the possible change in the material of support and provide recommendations for the technology of shield-driven tunneling.

Published: January 2022

Abstract
In the case of mechanical treatment of mine water in settling tanks according to the existing technology the concentration of suspended solids during the discharge of clarified effluents into water bodies does not correspond to the maximum permissible content of mechanical impurities set for surface water bodies. The technology of mine water cleaning has been improved due to the introduction of a horizontal settling tank of modernized construction and installation of purification of fast open granular filters with downward liquid flow at the final stage. The expected technological parameters of the proposed horizontal settling tank for the conditions of water disposal of the operating coal mining enterprise are determined. The dependences between the depth of sedimentation of particles of the suspension of a certain hydraulic size in the proposed horizontal settling tank, its length and clarifying efficiency of mine water pre-treated with a solution of aluminium sulphate are obtained. It is established that the overall efficiency of clarifying of mine waters pumped to the surface by a coal mining enterprise, after treatment by the proposed technology will be 94-95% of the initial concentration of suspended solids, which does not exceed the relevant quality of surface water.

Continuous-variable quantum repeaters based on bosonic error-correction and teleportation: architecture and applications
Authors: Wu Bo-Han , Zhang Zheshen , Zhuang Quntao 
Published: January 2022

Abstract
Quantum repeater is an essential ingredient for quantum networks that link distant quantum modules such as quantum computers and sensors. Motivated by distributed quantum computing and communication, quantum repeaters that relay discrete-variable quantum information have been extensively studied; while continuous-variable (CV) quantum information underpins a variety of quantum sensing and communication application, a quantum-repeater architecture for genuine CV quantum information remains largely unexplored. This paper reports a CV quantum-repeater architecture based on CV quantum teleportation assisted by the Gottesman–Kitaev–Preskill code to significantly suppress the physical noise. The designed CV quantum-repeater architecture is shown to significantly improve the performance of entanglement-assisted communication, target detection based on quantum illumination and CV quantum key distribution, as three representative use cases for quantum communication and sensing.

Abstract
Advances in quantum technology may come from the discovery of new materials systems that improve the performance or allow for new functionality in electronic devices. Lead telluride (PbTe) is a member of the group IV–VI materials family that has significant untapped potential for exploration. Due to its high electron mobility, strong spin–orbit coupling and ultrahigh dielectric constant it can host few-electron quantum dots and ballistic quantum wires with opportunities for control of electron spins and other quantum degrees of freedom. Here, we report the fabrication of PbTe nanowires by molecular beam epitaxy. We achieve defect-free single crystalline PbTe with large aspect ratios up to 50 suitable for quantum devices. Furthermore, by fabricating a single nanowire field effect transistor, we attain bipolar transport, extract the bandgap and observe Fabry–Pérot oscillations of conductance, a signature of quasiballistic transmission.
The terrors of Northanger Abbey
Authors: Keymer Tom 
Published: January 2022

Abstract
‘The terrors of Northanger Abbey’ examines themes of politics and society in Jane Austen’s Northanger Abbey, a work first drafted in 1798–9 and sold to a publisher in 1803, though it did not appear in print until a few months after her death in 1817. Biographers often note immediately personal ways in which the long-term upheaval precipitated by the French Revolution impinged on Austen’s mind. More important is the impact on the novels, an impact at its most conspicuous in this case. In Northanger Abbey, Austen deftly registers the fraught atmosphere of the revolution decade as it haunts her characters’ imaginations. More emphatically, she registers this atmosphere by playing with witty virtuosity on the literature of terror, and specifically the Gothic novel, as it pervaded the marketplace for print in the 1790s.
The voices of Pride and Prejudice
Authors: Keymer Tom 
Published: January 2022

Abstract
‘The voices of Pride and Prejudice’ focuses on Jane Austen’s narrative technique in Pride and Prejudice (1813). It was voice that mattered above all in Austen’s art, and it is in Pride and Prejudice, a masterpiece of less-is-more narration, that this pioneering aspect of her achievement is most clearly seen. A standard explanation for Austen’s virtuoso handling of narrative voice is that key features of her technique originate in the tradition of epistolary fiction, but other eighteenth-century subgenres are also important. Free indirect discourse was prominent in Pride and Prejudice. Austen has long been seen as the first major exponent of this technique, and she exploits it here to satirical ends in particular.
The silence at Mansfield Park
Authors: Keymer Tom 
Published: January 2022

Abstract
‘The silence at Mansfield Park’ assesses Jane Austen’s Mansfield Park (1814) with reference to abolitionist sympathies within Austen’s milieu and, more broadly, the commitment to thematic seriousness that accompanied her growing sense of authorship as a professional vocation. Alongside the works she first drafted in the 1790s, there is a new artistic maturity about Mansfield Park, and with it a more recognizably conservative outlook on moral and social questions. At the same time, trenchant satirical implications persist. Mansfield Park is sometimes seen as a novel with a glaring blind spot: a novel that indicates the dependence of its characters on income from a contaminated source, but fails to integrate the issue of slavery within the overall moral scheme. The Bertrams prove disinclined to talk about the slave trade, and ‘a dead silence’ falls when the heroine raises the subject. Their silence is laden with telling ironies, however, and Austen, as ever, communicates messages of her own between the lines.
Physicalism
Authors: Montero Barbara Gail 
Published: January 2022

Abstract
‘Physicalism’ looks at the view that everything that exists today—including human minds—came about in virtue of the rearrangements of and interactions between the physical particles and forces that emerged after the universe’s birth. There are a number of different versions of physicalism: identity theory, functionalism, mysterianism, eliminativism, non-reductive physicalism, and emergentism. The concept of multiple realization allows for the same type of mental states to have different neural signatures and contrasts physicalism with panpsychism, the view that the fundamental components of the universe are conscious. Most physicalists maintain the strongest philosophical argument for physicalism, what has come to be known as ‘the causal argument for physicalism’.
Intentionality
Authors: Montero Barbara Gail 
Published: January 2022

Abstract
‘Intentionality’ asks: what is distinctive about the mind? Some philosophers have argued that the mark of the mental is intentionality: the mind’s ability to represent things in the world. Beliefs, perceptions, desires, and hopes are intentional since they are about, or in some sense point to, things in the world. Different intentional states are thought to have distinct ‘directions of fit’. There are four interrelated puzzling features of intentionality. In addition, there are three theories of intentionality (the pictorial, causal, and teleological). Does intentionality pose a problem for physicalism?

Published: January 2022

Abstract
B-cell epitopes have the capability to recognize and attach to the surface of antigen receptors to stimulate the immune system against pathogens. Identification of B-cell epitopes from antigens has a great significance in several biomedical and biotechnological applications, provides support in the development of therapeutics, design and development of an epitope-based vaccine and antibody production. However, the identification of epitopes with experimental mapping approaches is a challenging job and usually requires extensive laboratory efforts. However, considerable efforts have been placed for the identification of epitopes using computational methods in the recent past but deprived of considerable achievements. In this study, we present LBCEPred, a python-based web-tool (http://lbcepred.pythonanywhere.com/), build with random forest classifier and statistical moment-based descriptors to predict the B-cell epitopes from the protein sequences. LBECPred outperforms all sequence-based available models that are currently in use for the B-cell epitopes prediction, with 0.868 accuracy value and 0.934 area under the curve. Moreover, the prediction performance of proposed models compared to other state-of-the-art models is 56.3% higher on average for Mathews Correlation Coefficient. LBCEPred is easy to use tool even for novice users and has also shown the models stability and reliability, thus we believe in its significant contribution to the research community and the area of bioinformatics.

AbstractMotivationWith the vast improvements in sequencing technologies and increased number of protocols, sequencing is being used to answer complex biological problems. Subsequently, analysis pipelines have become more time consuming and complicated, usually requiring highly extensive prevalidation steps. Here, we present SeqWho, a program designed to assess heuristically the quality of sequencing files and reliably classify the organism and protocol type by using Random Forest classifiers trained on biases native in k-mer frequencies and repeat sequence identities.ResultsUsing one of our primary models, we show that our method accurately and rapidly classifies human and mouse sequences from nine different sequencing libraries by species, library and both together, 98.32%, 97.86% and 96.38% of the time, respectively. Ultimately, we demonstrate that SeqWho is a powerful method for reliably validating the quality and identity of the sequencing files used in any pipeline.Availability and implementationhttps://github.com/DaehwanKimLab/seqwho.Supplementary informationSupplementary data are available at Bioinformatics online.
Topoisomerase II dysfunction causes metaphase I arrest by activating Aurora B, SAC and MPF and prevents PB1 abscission in mouse oocytes

Published: January 2022

Abstract
Oocyte aneuploidy is caused mainly by chromosome nondisjunction and/or unbalanced sister chromatid pre-division. Although studies in somatic cells have shown that topoisomerase II (TOP2) plays important roles in chromosome condensation and timely separation of centromeres, little is known about its role during oocyte meiosis. Furthermore, because VP-16, which is a TOP2 inhibitor and induces DNA double strand breaks, is often used for ovarian cancer chemotherapy, its effects on oocytes must be studied for ovarian cancer patients to recover ovarian function following chemotherapy. This study showed that inhibiting TOP2 with either ICRF-193 or VP-16 during meiosis I impaired chromatin condensation, chromosome alignment, TOP2α localization, and caused metaphase I (MI) arrest and first polar body (PB1) abscission failure. Inhibiting or neutralizing either spindle assembly checkpoint (SAC), Aurora B or maturation-promoting factor (MPF) significantly abolished the effect of ICRF-193 or VP-16 on MI arrest. Treatment with ICRF-193 or VP-16 significantly activated MPF and SAC but the effect disappeared when Aurora B was inhibited. Most of the oocytes matured in the presence of ICRF-193 or VP-16 were arrested at MI, and only 11–27% showed PB1 protrusion. Furthermore, most of the PB1 protrusions formed in the presence of ICRF-193 or VP-16 were retracted after further culture for 7 h. In conclusion, TOP2 dysfunction causes MI arrest by activating Aurora B, SAC, and MPF, and it prevents PB1 abscission by promoting chromatin bridges.
The Evolutionary Consequences of Dams and Other Barriers for Riverine Fishes
Authors: Zarri Liam J , Palkovacs Eric P , Post David M , Therkildsen Nina O , Flecker Alexander S 
Published: January 2022

AbstractDams and other anthropogenic barriers have caused global ecological and hydrological upheaval in the blink of the geological eye. In the present article, we synthesize 307 studies in a systematic review of contemporary evolution following reduced connectivity and habitat alteration on freshwater fishes. Genetic diversity loss was more commonly observed for small populations impounded in small habitat patches for many generations behind low-passability barriers. Studies show that impoundments can cause rapid adaptive evolution in migration timing, behavior, life history, temperature tolerance, and morphology, as well as reduce phenotypic variance, which can alter adaptive potential and ecological roles. Fish passage structures can restore migratory populations but also create artificial selection pressures on body size and migration. The accelerating pace of dam removals and the paucity of data for fishes other than salmonids, other vertebrates, invertebrates, and tropical and southern hemisphere organisms highlights the urgent need for more studies on the rapid evolutionary effects of dams.
Linking functional connectome gradient to individual creativity

Published: January 2022

Abstract

Introduction
Human brain network is organized as a hierarchical organization, exhibiting various connectome gradients. The principal gradient is anchored by the modality-specific primary areas and the transmodal regions. Previous studies have suggested that the unimodal-transmodal gradient in the functional connectome may offer an overarching framework for high-order cognitions of human brain. However, there is still a lacking of direct evidence to associate these two.

Objectives
Therefore, we aim to explore the association between creativity, a typical human high-order cognitive function, and unimodal-transmodal gradient, using two independent datasets of young adults.

Methods
For each individual, we identified the unimodal-transmodal gradient in functional connectome and calculated its global measures. Then we correlated the individual creativity score with measures of unimodal-transmodal gradient at global-brain, subsystem, and regional level.

Results
The results suggested that better creative performance was associated with greater distance between primary areas and transmodal regions in gradient axes, and less distance between ventral attention network and default mode network. Individual creativity was also found positively correlated with regional gradients in ventral attention network, and negatively correlated with gradients of regions in visual cortex.

Conclusion
Together, these findings directly link the unimodal-transmodal gradient to individual creativity, providing empirical evidence for the cognitive implications of functional connectome gradient.
How shared goals shape action monitoring

Published: January 2022

AbstractCooperation triggers expectations on our partners’ contributions to achieve a common goal. A partner, however, may sometimes violate such expectations, driving us to perform immediate adjustments. What neurophysiological mechanisms support these adaptations? We tested the hypothesis of an interaction-specific brain system that can decode a partner’s error and promote adaptive responses when cooperating toward a shared goal. During functional magnetic resonance imaging, the participants played short melodies with a virtual partner by performing one note each in turn-taking. A colored cue indicated which melody they had to execute at each trial, thus generating expectations on what notes the partner would play. The participants also performed the task in a perceptually matched Non-Interactive context. The results showed that task interactivity modulates the brain responses to a partner’s error in dorsal fronto-temporoparietal and medial cingulo-opercular networks. Multivariate pattern analysis revealed that these neural activations reflect deep decoding of the partner’s mistake. Within these networks, the automatic tendency to correct the partner’s errors, as indexed by specific reaction times adaptations, depended on the activity of a right-lateralized fronto-opercular system that may enable mutual support during real-life cooperation. Future studies may unveil the role of this putative “interaction monitoring” brain system in social dysfunctions and their motor foundations.
