description: The American lobster Homarus americanus is a decapod crustacean with both high economic and scientific importance. To facilitate physiological investigations of peptide transmitter/hormone function in this species, we have used matrix-assisted laser desorption/ionization Fourier transform mass spectrometry (MALDI-FTMS), matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS) and nanoscale liquid chromatography coupled to electrospray ionization quadrupole time-of-flight tandem mass spectrometry (nanoLC-ESI-Q-TOF-MS/MS) to elucidate the peptidome present in its nervous system and neuroendocrine organs. In total, 84 peptides were identified, including 27 previously known H. americanus peptides (e.g. VYRKPPFNGSIFamide [Val1-SIFamide]), 23 peptides characterized previously from other decapods, but new to the American lobster (e.g. pQTFQYSRGWTNamide [Arg7-corazonin]), and 34 new peptides de novo sequenced/detected for the first time in this study. Of particular note are a novel B-type allatostatin (TNWNKFQGSWamide) and several novel FMRFamide-related peptides, including an unsulfated analog of sulfakinin (GGGEYDDYGHLRFamide), two myosuppressins (QDLDHVFLRFamide and pQDLDHVFLRFamide), and a collection of short neuropeptide F isoforms (e.g. DTSTPALRLRFamide, and FEPSLRLRFamide). Our data also include the first detection of multiple tachykinin-related peptides in a non-brachyuran decapod, as well as the identification of potential individual-specific variants of orcokinin and orcomyotropin-related peptide. Taken collectively, our results not only expand greatly the number of known H. americanus neuropeptides, but also provide a framework for future studies on the physiological roles played by these molecules in this commercially and scientifically important species.

description: Evolutionary dynamics has been classically studied for homogeneous populations, but now there is a growing interest in the non-homogenous case. One of the most important models has been proposed by Lieberman, Hauert and Nowak, adapting to a weighted directed graph the classical process described by Moran. The Markov chain associated with the graph can be modified by erasing all non-trivial loops in its state space, obtaining the so-called Embedded Markov chain (EMC). The fixation probability remains unchanged, but the expected time to absorption (fixation or extinction) is reduced. In this paper, we shall use this idea to compute asymptotically the average fixation probability for complete bipartite graphs. To this end, we firstly review some recent results on evolutionary dynamics on graphs trying to clarify some points. We also revisit the 'Star Theorem' proved by Lieberman, Hauert and Nowak for the star graphs. Theoretically, EMC techniques allow fast computation of the fixation probability, but in practice this is not always true. Thus, in the last part of the paper, we compare this algorithm with the standard Monte Carlo method for some kind of complex networks.

description: We demonstrate that the property of being Alexandrov immersed is preserved along mean curvature flow. Furthermore, we demonstrate that mean curvature flow techniques for mean convex embedded flows such as noncollapsing and gradient estimates also hold in this setting. We also indicate the necessary modifications to the work of Brendle–Huisken to allow for mean curvature flow with surgery in the Alexandrov immersed, 2-dimensional setting.

description: In the last decade, enormous progress has been achieved in the understanding of the various facets of coalescing double neutron star and neutron black hole binary systems. One hopes that the mergers of such compact binaries can be routinely detected with the advanced versions of the ground-based gravitational wave detector facilities, maybe as early as in 2016. From the theoretical side, there has also been mounting evidence that compact binary mergers could be major sources of heavy elements and these ideas have gained recent observational support from the detection of an event that has been interpreted as a "macronova", an electromagnetic transient powered by freshly produced, radioactively decaying heavy elements. In addition, compact binaries are the most plausible triggers of short gamma-ray bursts (sGRBs) and the last decade has witnessed the first detection of a sGRB afterglow and subsequent observations have delivered a wealth of information on the environments in which such bursts occur. To date, compact binary mergers can naturally explain most --though not all-- of the observed sGRB properties. This article reviews major recent developments in various areas related to compact binary mergers.

description: We consider a bounded linear operator $T$ on a complex Banach space $X$ and show that its spectral radius $r(T)$ satisfies $r(T) < 1$ if all sequences $(< x',T^nx>)_{n \in \mathbb{N}_0}$ ($x \in X$, $x' \in X'$) are, up to a certain rearrangement, contained in a principal ideal of the space $c_0$ of sequences which converge to $0$. From this result we obtain generalizations of theorems of G. Weiss and J. van Neerven. We also prove a related result on $C_0$-semigroups.

description: Dual active bridge (DAB) converter is the key enabler in many popular applications such as wireless charging, electric vehicle and renewable energy. ZVS range and efficiency are two significant performance indicators for DAB converter. To obtain the desired ZVS and efficiency performance, modulation should be carefully designed. Hybrid modulation considers several single modulation strategies to achieve good comprehensive performance. Conventionally, to design a hybrid modulation, harmonic approach or piecewise approach is used, but they suffer from time-consuming model building process and inaccuracy. Therefore, an artificial-intelligence-based hybrid extended phase shift (HEPS) modulation is proposed. Generally, the HEPS modulation is developed in an automated fashion, which alleviates cumbersome model building process while keeping high model accuracy. In HEPS modulation, two EPS strategies are considered to realize optimal efficiency with full ZVS operation over entire operating ranges. Specifically, to build data-driven models of ZVS and efficiency performance, extreme gradient boosting (XGBoost), which is a state-of-the-art ensemble learning algorithm, is adopted. Afterwards, particle swarm optimization with state-based adaptive velocity limit (PSO-SAVL) is utilized to select the best EPS strategy and optimize modulation parameters. With 1 kW hardware experiments, the feasibility of HEPS has been verified, achieving optimal efficiency with maximum of 97.1% and full-range ZVS operation.

description: Imprinted genes defy rules of Mendelian genetics with their expression tied to the parent from whom each allele was inherited. They are known to play a role in various diseases/disorders including fetal growth disruption, lower birth weight, obesity, and cancer. There is increasing interest in understanding their influence on environmentally-induced disease. The environment can be thought of broadly as including chemicals present in air, water and soil, as well as food. According to the Agency for Toxic Substances and Disease Registry (ATSDR), some of the highest ranking environmental chemicals of concern include metals/metalloids such as arsenic, cadmium, and lead. The complex relationships between toxic metal exposure, imprinted gene regulation/expression and health outcomes are understudied. Herein we examine trends in imprinted gene biology, including an assessment of the imprinted genes and their known functional roles in the cell, particularly as they relate to toxic metals exposure and disease. The data highlight that many of the imprinted genes have known associations to developmental diseases and are enriched for their role in the TP53 and AhR pathways. Assessment of the promoter regions of the imprinted genes resulted in the identification of an enrichment of binding sites for two transcription factor families, namely the zinc finger family II and PLAG transcription factors. Taken together these data contribute insight into the complex relationships between toxic metals in the environment and imprinted gene biology.

description: The dual active bridge (DAB) converter has been popular in many applications for its outstanding power density and bidirectional power transfer capacity. Up to now, triple phase shift (TPS) can be considered as one of the most advanced modulation techniques for DAB converter. It can widen zero voltage switching range and improve power efficiency significantly. Currently, current stress of the DAB converter has been an important performance indicator when TPS modulation is applied for smaller size and higher efficiency. However, to minimize the current stress when the DAB converter is under TPS modulation, two difficulties exist in analysis process and realization process, respectively. Firstly, three degrees of modulation variables in TPS modulation bring challenges to the analysis of current stress in different operating modes. This analysis and deduction process leads to heavy computational burden and also suffers from low accuracy. Secondly, to realize TPS modulation, if a lookup table is adopted after the optimization of modulation variables, modulation performance will be unsatisfactory because of the discrete nature of lookup table. Therefore, an AI-based TPS modulation (AI-TPSM) strategy is proposed in this paper. Neural network (NN) and fuzzy inference system (FIS) are utilized to deal with the two difficulties mentioned above. With the proposed AI-TPSM, the optimization of TPS modulation for minimized current stress will enjoy high degree of automation which can relieve engineers' working burden and improve accuracy. In the end of this paper, the effectiveness of the proposed AI-TPSM has been experimentally verified with a 1 kW prototype.

Cigar Lake Mine Convolutional Neural Network
Creators: name: Morgenroth, Josephine
Publisher: name: Zenodo
Year: 2021

description: A Convolutional Neural Network (CNN) was developed for Cigar Lake Mine, Saskatchewan, Canada, to predict tunnel liner yield. The mine experiences a complex time-dependent ground squeezing behaviour resulting from the poor geological conditions and the artificial ground freezing implemented to stabilize the ore cavities and to control ground water during the ore extraction process. Four inputs were used inn the CNN to make this prediction: geotechnical zone mapping, primary support class, ground freezing pattern, and measured tunnel displacement. A sensitivity analysis of the CNN training parameters, called hyperparameters, was completed to optimize the final CNN performance. Hyperparameters analyzed include: the amount of training data, the convolutional filter size, and the error weighting scheme. Two final models were developed, one balanced model able to accurately predict tunnel liner yield across all classes of severity, and one targeted model that is calibrated to predict the higher classes of tunnel liner yield particularly well. Input Variable Selection (IVS) was applied to examine how the CNN used the given data, or inputs, to forecast rock mass behaviour. The three IVS methods investigated were Channel Activation Strength (CAS), Input Omission (IO), and Partial Correlation (PC). The IO and PC approaches proposed are novel for CNNs using a spatial and temporal geomechanical dataset.

description: By means of detailed Monte Carlo (MC) simulations, we have presented dynamic phase transition (DPT) properties of ferromagnetic thin-films. Thermal variations of surface, bulk and total dynamical order parameters (DOP) for a film and total order parameter for the films with different thicknesses have been examined. Opposite regimes of the critical value of reduced exchange interaction (surface to bulk ratio) $R_{c}$ at which the critical temperature becomes independent of film thickness $L$ has been also taken into consideration. The average magnetizations of each layer is reversed in these regimes. Based on the results, we have confirmed that the system represents a crossover behavior in between ordinary to extraordinary transition in the presence of surface exchange enhancement.

description: The Nelson-Siegel framework is employed to model the term structure of commodity futures prices. Exploiting the information embedded in the level, slope and curvature parameters, we develop novel investment strategies that assume short-term continuation of recent parallel, slope or butterfly movements of futures curves. Systematic strategies based on the change in the slope generate significant profits that are unrelated to previously documented risk factors and can survive reasonable transaction costs. Further analysis demonstrates that the profitability of the slope strategy increases with investor sentiment and is in part a compensation for the drawdowns incurred during economic slowdowns. The profitability can also be magnified through timing and persists under alternative specifications of the Nelson-Siegel model.

description: We have determined the relation between the AGN luminosities at rest-frame 6 μm associated to the dusty torus emission and at 2-10 keV energies using a complete, X-ray flux limited sample of 232 AGN drawn from the Bright Ultra-hard XMM-Newton Survey. The objects have intrinsic X-ray luminosities between 10^42 and 10^46 erg/s and redshifts from 0.05 to 2.8. The rest-frame 6 μm luminosities were computed using data from the Wide-Field Infrared Survey Explorer and are based on a spectral energy distribution decomposition into AGN and galaxy emission. The best-fit relationship for the full sample is consistent with being linear, L_6 μm $\propto$ L_2-10 keV^0.99$\pm$0.032, with intrinsic scatter, ~0.35 dex in log L_6 μm. The L_6 μm/L_2-10 keV luminosity ratio is largely independent on the line-of-sight X-ray absorption. Assuming a constant X-ray bolometric correction, the fraction of AGN bolometric luminosity reprocessed in the mid-IR decreases weakly, if at all, with the AGN luminosity, a finding at odds with simple receding torus models. Type 2 AGN have redder mid-IR continua at rest-frame wavelengths <12 μm and are overall ~1.3-2 times fainter at 6 μm than type 1 AGN at a given X-ray luminosity. Regardless of whether type 1 and type 2 AGN have the same or different nuclear dusty toroidal structures, our results imply that the AGN emission at rest-frame 6 μm is not isotropic due to self-absorption in the dusty torus, as predicted by AGN torus models. Thus, AGN surveys at rest-frame 6 μm are subject to modest dust obscuration biases.

description: Gene targeting in mice was used to investigate the unknown function of Scp2, encoding sterol carrier protein-2 (SCP2; a peroxisomal lipid carrier) and sterol carrier protein-x (SCPx; a fusion protein between SCP2 and a peroxisomal thiolase). Complete deficiency of SCP2 and SCPx was associated with marked alterations in gene expression, peroxisome proliferation, hypolipidemia, impaired body weight control, and neuropathy. Along with these abnormalities, catabolism of methyl-branched fatty acyl CoAs was impaired. The defect became evident from up to 10-fold accumulation of the tetramethyl-branched fatty acid phytanic acid in Scp2(−/−) mice. Further characterization supported that the gene disruption led to inefficient import of phytanoyl-CoA into peroxisomes and to defective thiolytic cleavage of 3-ketopristanoyl-CoA. These results corresponded to high-affinity binding of phytanoyl-CoA to the recombinant rat SCP2 protein, as well as high 3-ketopristanoyl-CoA thiolase activity of the recombinant rat SCPx protein.

description: Cet article s’occupe d’une des rares représentations haïtiennes de la révolution haïtienne sous forme romanesque: La danse sur le volcan de Marie Vieux-Chauvet (1958) raconte l'insurrection des gens de couleur à la fin du XVIIIe siècle et donne un commentaire sur le projet national (débuts de la dictature de Duvalier) dans les années cinquante du XXe siècle. L'analyse discute la femme de couleur en tant que synecdoque de la position intermédiaire des gens de couleur, notamment par rapport à leur rôle dans la narration de la révolution. Ce récit des transformations radicales d'une société raconte en même temps l’essai de la fondation de la nation. L’article analyse également la mise en parallèle des espaces du théâtre et de la société coloniale, à savoir le rôle du théâtre en tant qu'hétérotopie de la société coloniale et de sa transformation voire sa destruction. La négociation des conflits d'intérêts se présente comme une mise en scène qui caractérise les différents groupes par des formes spécifiques de violence, tout en les opposant en tant que citoyens d'une même société nationale.

description: This article analyzes Christian, Muslim, and Hindu-based discourses and practices in relation to sufficiency, materialism, and the good life in the context of the European Union. The current political and scholarly debate emphasizes the need for a sustainability transformation and, more specifically, for reductions in resource use by the global consumer class. Within this discussion, the different approaches to and interpretations of the various facets of ecology and materialism, and the links between them, have become the primary focus. Questions about what a "good life", as opposed to a consumerist lifestyle, means and the need to focus on sufficiency rather than efficiency are being (re-)considered. Given that religions and faith-based actors (FBAs) play an essential role as interpreters of norms and values in societies, especially when societies are facing particular challenges, it is important to understand how they communicate information about relevant ideas and actions. What do FBAs say about sustainable lifestyles, sufficiency, and the role of materialism vis-à-vis those two ideas? How do they relate it all to questions of faith? Do they use faith-based or secular idioms to address the ideas? How do FBAs relate the ideas to practices? To begin answering these questions, we here present a content analysis of relevant texts and supplement the finding thereof with an analysis of expert interviews. The results come mainly from faith-based actors active on the EU level. Nevertheless, some of the actors also operate globally, which is why a clear, sharp regional separation is not entirely possible. This article identifies and explores the role of faith-based ideas and practices in maneuvering toward one of the most substantial societal challenges in this period of late capitalism and its materialist dimension. The regional focus imposes limitations on the scope of the religions in our sample, which is most evident in the case of Hinduism: here, it was only possible to include one organization in particular (Brahma Kumaris) in the empirical analysis. These practical limitations must therefore be taken into account when considering the scope of the results of this analysis.

Garson Mine Long Short-Term Memory Network

Publisher: name: Zenodo

description: Digitalization of underground excavations has resulted in increasing access to large amounts of data for rock engineering professionals. Data-driven approaches, such as machine learning algorithms, present an opportunity to aid data interpretation. At Garson Mine, a 112-year-old nickel mine near Sudbury, Canada, the microseismic database is used to manually calibrate a complex mine-scale finite difference model, which is in turn used to assess seismic risk to inform mine operations and scheduling. The manual model calibration is tedious and time consuming. This research proposes a Long-Short Term Memory (LSTM) network to assist in finite difference model calibration by forecasting the stresses in the model. The LSTM is trained using the microseismic database, the geology and geomechanical parameters from the existing FLAC3D model. Two LSTM networks are developed and compared for Garson Mine: one that predicts the principal stresses and another that predicts the six-component stress tensor at each zone centroid in the FLAC3D model. Various LSTM network hyperparameters were analyzed to determine the optimal architecture for the two sets of targets, including: input encoding and pre-processing, training solver, network layer architecture, and cost function. Architectures were chosen based on three performance metrics: the corrected Akaike Information Criterion (AICc), coefficient of determination (R2), and percent capture (%C). This study found that similar LSTM network architectures are able to adequately predict both principal stresses and the complete stress tensor, however, the ensemble variance was larger when predicting the complete stress tensor. When predicting the principal stresses, AICc was -59.62, R2 was 0.996, and %C was 97%, and when predicting the six-component stress tensor AICc was -45.50, R2 was 0.997, and %C was 80%. This research represents progress towards continuous, automated calibration of complex numerical models, whereby earlier and more accurate forecasts of changes in stress conditions will allow earlier intervention and reaction to challenging stress environments, leading to increased safety of excavations and mine personnel.
An exploratory study of recharging mechanisms in a shared service context

Subjects: subject: 150399 Business and Management not elsewhere classified
subject: FOS: Economics and business

description: It is claimed that the transformation of business support services through some form of ‘externalization’ mechanism such as the shared service centre (SSC) model can drive down costs and enhance functionality. A key characteristic of the SSC’s rationale is its ability change by replicate the characteristics of third-party outsourcing, whilst also retaining overall management control within the boundaries of the organization. In such a market-oriented model, it should follow that a key feature of an SSC is the recharging of its costs to its customers, the business facing operational units. Yet, in offering a hybrid solution combining characteristics of market and hierarchy, it could be expected that the recharging for support services will seek to combine the tenets of both market-orientated transfer pricing with cost allocation methods traditionally associated with internal cost centres. The motivation of this study is the increasing prevalence of the SSC model amongst large organizations in the face of a relative paucity of contemporary literature on transfer pricing and cost allocation in new organizational forms, especially the SSC model. The central theme of this study is to explore the recharging mechanisms applied by different SSCs and their organizational effects in terms of balancing market coordination between the SSC and its customers and top management control. Three case studies were undertaken to explore how SSCs recharge the costs for the finance function as a business support services and the effects on managerial behaviours of both the SSC and business units. Drawing on theory of organizational structure, transaction cost economics (TCE) and agency theory, a conceptual framework was constructed to guide the analysis of the empirical evidence. The findings of this study include: 1) The choice of recharging method can be either transfer pricing approach (direct recharge) or cost allocation (indirect recharge), contingent upon; the governance orientation of each organization, asset specificity and extent of transactions, uncertainty and opportunism and bounded rationality. 2) Mandating the choice of recharging mechanism given the asymmetric bargaining power between the SSC and the head office could cause agency problems within the organizations, although this could be mitigated by transparency of information, appropriate coordination mechanisms, and performance measurement based on mutually agreed budget targets. 3) Recharging mechanism is fluid over time and in one of the cases (i.e. DHL Express) it is found that the transfer pricing can be used in the first stages of SSC implementation to drive change, but on maturity there is a reversion to broad brush cost allocation to better enable overall system optimization with reduced transaction costs.
Pom1p, a fission yeast protein kinase that provides positional information for both polarized growth and cytokinesis
Creators: name: Bahler, J.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1998

description: Schizosaccharomyces pombe cells have a well-defined pattern of polarized growth at the cell ends during interphase and divide symmetrically into two equal-sized daughter cells. We identified a gene, pom1, that provides positional information for both growth and division in S. pombe. pom1 mutants form functioning growth zones and division septa but show several abnormalities: (1) After division, cells initiate growth with equal frequencies from either the old or the new end; (2) most cells never switch to bipolar growth but instead grow exclusively at the randomly chosen end; (3) some cells mislocalize their growth axis altogether, leading to the formation of angled and branched cells; and (4) many cells misplace and/or misorient their septa, leading to asymmetric cell division. pom1 encodes a putative protein kinase that is concentrated at the new cell end during interphase, at both cell ends during mitosis, and at the septation site after mitosis. Small amounts of Pom1p are also found at the old cell end during interphase and associated with the actin ring during mitosis. Pom1p localization to the cell ends is independent of actin but requires microtubules and Tea1p. pom1 mutations are synthetically lethal with several other mutations that affect cytokinesis and/or the actin or microtubule cytoskeleton. Thus, Pom1p may position the growth and cytokinesis machineries by interaction with both the actin and microtubule cytoskeletons.

description: Η διπλωματική εργασία έχει ως θέμα το φαινόμενο των εναλλακτικών αντιλήψεων των μαθητών στη διδακτική των Φυσικών Επιστημών και στοχεύει στην ενίσχυση της γενικότερης προσπάθειας των μελετητών και των εκπαιδευτικών για την εύρεση και ανάλυση μίας ασφαλής και αξιόπιστης μεθόδου αντιμετώπισης του φαινομένου. Πρόκειται για μία ποσοτική έρευνα στην οποία συγκρίνονται η παραδοσιακή μέθοδος διδασκαλίας, το εργαστηριακό πείραμα και η προσομοίωση ως προς την αποτελεσματικότητά τους στη διαδικασία της αναδόμησης αυτών των αντιλήψεων και αποσκοπεί στην εξαγωγή έγκυρων αποτελεσμάτων και συμπερασμάτων σχετικά με το αν η πειραματική μέθοδος, και συγκεκριμένα η εικονική της μορφή, μπορεί να αποτελέσει μία πιο αποτελεσματική μέθοδο εννοιολογικής αλλαγής από τις υπόλοιπες. Η σύγκριση μεταξύ των μεθόδων πραγματοποιήθηκε με την εξ αποστάσεως και ασύγχρονη συλλογή δεδομένων μέσω ψηφιακών ερωτηματολογίων, τα οποία περιείχαν διδασκαλίες πέντε φαινομένων των Φυσικών Επιστημών, στα οποία συναντώνται εναλλακτικές αντιλήψεις και μοιράστηκαν σε μαθητές της Γ’ τάξης του Γυμνασίου, οι οποίοι αποτέλεσαν το δείγμα της έρευνας. Τα δεδομένα ποσοτικοποιήθηκαν και αναλύθηκαν με τη βοήθεια στατιστικών εργαλείων καταλήγοντας στα συμπεράσματα πως οι μέθοδοι είναι εξίσου αποτελεσματικές στη διαδικασία αναδόμησης των αντιλήψεων, με την προσομοίωση να παρουσιάζει καλύτερα αποτελέσματα και πως η αναδόμηση αποτελεί δυσκολότερη διαδικασία από την κατανόηση.

description: Η παρούσα εργασία εξετάζει το μείζον θέμα του ασφαλιστικού στη χώρα μας εστιάζοντας παράλληλα στο κίνδυνο μακροζωίας (longevity risk). Στο πρώτο κομμάτι αναλύεται η ασφαλιστική συνείδηση των Ελλήνων για την διαφύλαξη ικανού εισοδήματος στα χρόνια της συνταξιοδότησης και η σύγκριση με άλλες χώρες. Στο δεύτερο κομμάτι αναλύεται η έννοια του longevity risk και το κατά πόσο είμαστε προετοιμασμένοι ώστε να αντιμετωπίσουμε την αύξηση του προσδόκιμου ζωής. Για τον λόγο αυτό, δημιουργήσαμε ένα ερωτηματολόγιο 28 ερωτήσεων, σκοπός του οποίου ήταν να καταγράψουμε τις απαντήσεις των ερωτηθέντων αναφορικά με τη διαφύλαξη ικανού εισοδήματος στη σύνταξη, την άποψη τους για τον πληθωρισμό, τις επενδυτικές τους στρατηγικές κλπ. Η συμβολή μου στην εργασία είναι η δημιουργία αυτής της έρευνας μέσω της οποίας γίνεται αντιληπτό ότι ο συνταξιοδοτικός αλφαβητισμός είναι σε χαμηλά επίπεδα στην χώρα μας.

description: Online science dissemination has quickly become crucial in promoting scholars' work. Recent literature has demonstrated a lack of visibility for women's research, where women's articles receive fewer academic citations than men's. The informetric and scientometric community has briefly examined gender-based inequalities in online visibility. However, the link between online sharing of scientific work and citation impact for teams with different gender compositions remains understudied. Here we explore whether online visibility is helping women overcome the gender-based citation penalty. Our analyses cover the three broad research areas of Computer Science, Engineering, and Social Sciences, which have different gender representation, adoption of online science dissemination practices, and citation culture. We create a quasi-experimental setting by applying Coarsened Exact Matching, which enables us to isolate the effects of team gender composition and online visibility on the number of citations. We find that online visibility positively affects citations across research areas, while team gender composition interacts differently with visibility in these research areas. Our results provide essential insights into gendered citation patterns and online visibility, inviting informed discussions about decreasing the citation gap.

description: A measurement has been made of the radiation damage incurred by the ATLAS Pixel Detector barrel silicon modules from the beginning of operations through the end of 2012. This translates to hadronic fluence received over the full period of operation at energies up to and including 8 TeV. The measurement is based on a per-module measurement of the silicon sensor leakage current. The results are presented as a function of integrated luminosity and compared to predictions by the Hamburg Model. This information can be used to predict limits on the lifetime of the Pixel Detector due to current, for various operating scenarios.

description: We calculate the next-to-leading order(NLO) quantum chromodynamics(QCD) corrections to the inclusive process of $Z_0 \rightarrow B^*_c+\bar{c}+b$ under the non-relativistic QCD(NRQCD) factorization scheme. Technical details about contributions from vector and axial-vector currents in dimensional regularization scheme are discussed. Numerical calculation shows that the NLO correction enhances the leading-order decay width by about 50%, and the dependence on renormalization scale $μ$ is reduced. The uncertainties induced by quark masses and the renormalization scale $μ$ are also analyzed.

description: We express supersymmetric couplings among the vector and the tensor multiplets in six dimensions (6D) in terms of N=1 superfields. The superfield description is derived from the invariant action in the projective superspace. The obtained expression is consistent with the known superfield actions of 6D supersymmetric gauge theory and 5D Chern-Simons theory after the dimensional reduction. Our result provides a crutial clue to the N=1 superfield description of 6D supergravity.

Critical role for Atm in suppressing V(D)J recombination-driven thymic lymphoma

description: Chromosome translocations involving T cell receptor (TCR) loci have been found in tumors from Ataxia telangiectasia (AT) patients and in mouse Atm−/− thymoma, suggesting the involvement of V(D)J recombination in these malignancies. By introducing a RAG-1 deficiency into Atm−/− mice in the presence of a TCR transgene, we show that V(D)J recombination is critical for thymoma development in these mice. Therefore, aberrant V(D)J recombination, normally suppressed by Atm, facilitates tumorigenic events leading to cancer. Because V(D)J recombination is dispensable for lymphomagenesis upon p53 deficiency, this study also indicates that Atm and p53 function by distinct mechanisms in suppressing thymoma.
A Cyber-Physical Routing Protocol Exploiting Trajectory Dynamics for Mission-Oriented Flying Ad Hoc Networks

description: As a special type of mobile ad hoc network (MANET), the flying ad hoc network (FANET) has the potential to enable a variety of emerging applications in both civilian wireless communications (e.g., 5G and 6G) and the defense industry. The routing protocol plays a pivotal role in FANET. However, when designing the routing protocol for FANET, it is conventionally assumed that the aerial nodes move randomly. This is clearly inappropriate for a mission-oriented FANET (MO-FANET), in which the aerial nodes typically move toward a given destination from given departure point(s), possibly along a roughly deterministic flight path while maintaining a well-established formation, in order to carry out certain missions. In this paper, a novel cyber-physical routing protocol exploiting the particular mobility pattern of an MO-FANET is proposed based on cross-disciplinary integration, which makes full use of the mission-determined trajectory dynamics to construct the time sequence of rejoining and separating, as well as the adjacency matrix for each node, as prior information. Compared with the existing representative routing protocols used in FANETs, our protocol achieves a higher packet-delivery ratio (PDR) at the cost of even lower overhead and lower average end-to-end latency, while maintaining a reasonably moderate and stable network jitter, as demonstrated by extensive ns-3-based simulations assuming realistic configurations in an MO-FANET.

description: High-resolution observations of the solar photosphere have identified a wide variety of spiralling motions in the solar plasma. These spirals vary in properties, but are observed to be abundant at the solar surface. In this work these spirals are studied for their potential as magnetohydrodynamic (MHD) wave generation mechanisms. The inter-granular lanes, where these spirals are commonly observed, are also regions where the magnetic field strength is higher than average. This combination of magnetic field and spiralling plasma is a recipe for the generation of Alfvén waves and other MHD waves. This work employs numerical simulations of a self-similar magnetic flux tube embedded in a realistic, gravitationally stratified, solar atmosphere to study the effects of a single magnetic flux tube perturbed by a logarithmic velocity spiral driver. The expansion factor of the logarithmic spiral driver is varied and multiple simulations are run for a range of values of the expansion factor centred around observational constraints. The simulations are analysed using `flux surfaces' constructed from the magnetic field lines so that the vectors perpendicular, parallel and azimuthal to the local magnetic field vector can be calculated. The results of this analysis show that the Alfvén wave is the dominant wave for lower values of the expansion factor, whereas, for the higher values the parallel component is dominant. This transition occurs within the range of the observational constraints, meaning that spiral drivers, as observed in the solar photosphere, have the potential to generate a variety of MHD wave modes.
