description: Estimating body mass and locomotor habits of fossil rodents is challenging for taxa without available postcranial material. Although equations exist to estimate body mass from dental dimensions based on extant rodents, the applicability of such equations is doubtful given that modern rodents have evolved highly specialized teeth, whereas fossil taxa often exhibit a much less derived condition. For the present study, 11 cranial variables from a sample of 203 extant rodents of known body mass representing a range of taxonomic groups were assessed using reduced major axis (RMA) regression. The results show a strong correlation between body mass and each of the 11 cranial variables. The best estimators for body mass are skull length and cheek-tooth area, whereas the least reliable measures are palate length, and foramen magnum, as well as braincase and occipital condyle dimensions. We estimated body mass for specimens of five fossil Ischyromyidae rodents for which body mass had never been estimated (Paramys copei, P. delicatus, Reithroparamys delicatissimus, Rapamys atramontis, and Ischyromys typus). Principal components and canonical variates analyses based on 10 cranial dimensions for 103 members of Sciuromorpha demonstrate that a relationship exists between locomotor habits and cranial variables in this suborder. In these analyses, early ischyromyids are all placed in the terrestrial group with Aplodontia, Marmota, Cynomys, and Spermophilus. This contradicts previous hypotheses regarding early rodent locomotion, which suggested that they were arboreal or more generalized in their habits.

GRB Durations and Fluences are Underestimated

Publisher: name: Zenodo

description: In this study we investigated how Gamma-Ray Burst (GRB) prompt duration and fluence measurements are affected by increasing source redshift. We took bright GRBs observed by the Burst Alert Telescope on board the Neil Gehrels Swift Observatory (Swift/BAT) at redshifts z<1 and simulated what Swift/BAT would have observed if the GRBs were instead at higher redshifts (i.e., z>3), taking into account proper distance corrections and instrument response folding. We then used a Bayesian block algorithm to measure the duration of the simulated GRBs. We found that almost all durations and fluences measured for simulated high-z simulated GRBs are shorter than their observed durations when corrected for time dilation and luminosity distance, respectively.  The underestimations are due to low signal-to-noise burst emission being lost into the background, i.e., the so-called “tip-of-the-iceberg” effect. The amount of signal lost depends on light curve structure and brightness. We then compared the duration and fluence distributions of the GRBs we simulated at high-z to that of Swift/BAT GRBs observed at high redshifts and found that the two samples are consistent. These results imply that the GRB prompt duration and fluences of high-z GRBs observed by Swift/BAT are all underestimations.

description: We prove that the quantum graph algebra and the quantum moduli algebra associated to a punctured sphere and complex semisimple Lie algebra $\mathfrak{g}$ are Noetherian rings and finitely generated rings over $\mathbb{C}(q)$. Moreover, we show that these two properties still hold on $\mathbb{C}\big[q,q^{-1}\big]$ for the integral version of the quantum graph algebra. We also study the specializations $\mathcal{L}_{0,n}^ε$ of the quantum graph algebra at a root of unity $ε$ of odd order, and show that $\mathcal{L}_{0,n}^ε$ and its invariant algebra under the quantum group $U_ε(\mathfrak{g})$ have classical fraction algebras which are central simple algebras of PI degrees that we compute.

description: Multi-TeV muon colliders promise an unprecedented potential for exploring the particle-physics energy frontier, and, at the same time, can probe with fantastic accuracy the precise structure of the Standard Model, and in particular of the Higgs boson sector. Here we consider the possibility to measure the loop-suppressed single-, double-, triple-Higgs boson production mediated by the collinear-photon scattering in the channels $μ^+μ^-\toμ^+μ^-γ^\ast γ^\ast \to μ^+μ^- [H,HH,HHH]$. We study total rates and kinematical distributions in the Standard Model, and compare them with the corresponding vector-boson-fusion processes $V^\ast V^\ast\to H,HH,HHH$ at muon collisions center-of-mass energies in the range between 1.5 and 100 TeV. Possible strategies for enhancing the $γγ\to H,HH,HHH$ signal over the dominant vector-boson-fusion production are proposed. The sensitivity of total rates to possible anomalies in the Higgs-boson self-couplings is also discussed.

description: The factor-augmented vector autoregressive (FAVAR) model, first proposed by Bernanke, Bovin, and Eliasz (2005, QJE), is now widely used in macroeconomics and finance. In this model, observable and unobservable factors jointly follow a vector autoregressive process, which further drives the comovement of a large number of observable variables. We study the identification restrictions for FAVAR models, and propose a likelihood-based two-step method to estimate the model. The estimation explicitly accounts for factors being partially observed. We then provide an inferential theory for the estimated factors, factor loadings and the dynamic parameters in the VAR process. We show how and why the limiting distributions are different from the existing results.

description: Neural Architecture Search (NAS) aims to automatically find effective architectures within a predefined search space. However, the search space is often extremely large. As a result, directly searching in such a large search space is non-trivial and also very time-consuming. To address the above issues, in each search step, we seek to limit the search space to a small but effective subspace to boost both the search performance and search efficiency. To this end, we propose a novel Neural Architecture Search method via Dominative Subspace Mining (DSM-NAS) that finds promising architectures in automatically mined subspaces. Specifically, we first perform a global search, i.e ., dominative subspace mining, to find a good subspace from a set of candidates. Then, we perform a local search within the mined subspace to find effective architectures. More critically, we further boost search performance by taking well-designed/ searched architectures to initialize candidate subspaces. Experimental results demonstrate that DSM-NAS not only reduces the search cost but also discovers better architectures than state-of-the-art methods in various benchmark search spaces.

description: Photonic bound states in the continuum are spatially localised modes with infinitely long lifetimes that exist within a radiation continuum at discrete energy levels. These states have been explored in various systems where their emergence is either guaranteed by crystallographic symmetries or due to topological protection. Their appearance at desired energy levels is, however, usually accompanied by non-BIC resonances, from which they cannot be disentangled. Here, we propose a new generic mechanism to realize bound states in the continuum that exist by first principles free of other resonances and are robust upon parameter tuning. The mechanism is based on the fundamental band in double-net metamaterials, which provides vanishing homogenized electromagnetic fields. We predict two new types of bound states in the continuum: i) generic modes confined to the metamaterial bulk, mimicking electronic acoustic waves in a hydrodynamic double plasma, and ii) topological surface bound states in the continuum.

description: A new Schiff base, H2L, was prepared by condensation of 4,6-diacetylresorcinol with o-phenylenediamine in molar ratio 1 : 1. The ligand reacted with copper(II), nickel(II), cobalt(II), iron(III), zinc(II), oxovanadium(IV), and dioxouranium(VI) ions in the absence and presence of LiOH to yield mononuclear and homobinuclear complexes. The mononuclear dioxouranium(VI) complex [(HL)-(UO2)(OAc)(H2O)]·5H2O was used to synthesize heterobinuclear complexes. The ligand and its metal complexes were characterized by elemental analyses, IR, 1H-, and 13C-NMR, electronic, ESR and mass spectra, conductivity, and magnetic susceptibility measurements as well as thermal analysis. In the absence of LiOH, mononuclear complexes (1, 4, and 9) were obtained; in the presence of LiOH, binuclear complexes (3, 5, 7, and 10) as well as mononuclear complexes (2, 6, and 8) were obtained. In the mononuclear complexes, the coordinating sites are the phenolic oxygen, azomethine nitrogen, and amino nitrogen. In addition to these coordinating sites, the free carbonyl and phenolic OH are involved in coordination in binuclear complexes. The metal complexes exhibited octahedral, tetrahedral, and square planar geometries while the uranium is seven-coordinate. The antimicrobial and antioxidant activities of the ligand and its complexes were investigated. The ligand and the metal complexes showed antitumor activity against Ehrlich Acites Carcinoma.

description: Promotion and rowmotion are intriguing actions in dynamical algebraic combinatorics which have inspired much work in recent years. In this paper, we study $P$-strict labelings of a finite, graded poset $P$ of rank $n$ and labels at most $q$, which generalize semistandard Young tableaux with $n$ rows and entries at most $q$, under promotion. These $P$-strict labelings are in equivariant bijection with $Q$-partitions under rowmotion, where $Q$ equals the product of $P$ and a chain of $q-n-1$ elements. We study the case where $P$ equals the product of chains in detail, yielding new homomesy and order results in the realm of tableaux and beyond. Furthermore, we apply the bijection to the cases in which $P$ is a minuscule poset and when $P$ is the three element $V$ poset. Finally, we give resonance results for promotion on $P$-strict labelings and rowmotion on $Q$-partitions.

Cognitive performance

description: Adolescent type 2 diabetes (T2D) diagnoses are on the rise. Consistent with the adult literature, preliminary evidence in adolescents suggests that T2D is associated with reduced brain volume and white matter microstructural integrity. As part of the Cognitive Performance in Adolescents with T2D (CPAT2D) study, this project aimed to test whether T2D diagnosis is associated with poorer cognitive performance in adolescents. Five adolescents with obesity and T2D (60% female; body mass index [BMI] percentile 98.2 ± 2.0; age 16.7 ± 1.1 years) were recruited and matched to two control adolescents with obesity but without T2D (50% female; BMI percentile 99.9 ± 0.2; age 15.9 ± 1.3 years) on at least three of the following characteristics: age, sex, pubertal stage and habitual sleep duration. All participants wore a wrist actigraphy device for seven consecutive nights to measure sleep at home and then completed two neuromotor cognitive tasks at a laboratory testing session assessing motor preparation (simple reaction time task) and executive functioning (affective shifting task [AST]). Control data were available through the Sleep Manipulation in Adolescents at Risk of Type 2 Diabetes (SMART2D) study. Premotor reaction time outcomes in either task and proportions of commission and omission error trials in the AST were subsequently analyzed. Based on this preliminary participant sample, there is no evidence to suggest that adolescents with compared to without T2D perform differently on the neuromotor cognitive tasks. The results should be confirmed once the intended sample size is reached. In the meantime, clinicians should monitor for changes in cognitive function in adolescents with T2D, perhaps by asking about academic achievement. The majority of our sample exhibited sub-optimal movement behaviours; to preserve overall health, adolescents with obesity and/or T2D should strive to meet sleep, physical activity and screen time recommendations for their age group.

description: PhD thesis (submitted July 2015). Genetic association studies have discovered many variants which influence type 1 diabetes (T1D) risk and further correlate with quantitative cell-type specific phenotypes. However, disease associated differences can be small, and large numbers of samples are required to overcome the heterogeneity that exists between humans.
Novel high-throughput biotechnologies measure large number of samples but technical or within-batch variation, may undermine reproducibility of measurements. In my thesis, I analyse two types of these datasets, central to the study of T1D. The first is generated by flow cytometry, a biotechnology utilising light scatter and fluorescently stained markers to discriminate different cell types. Unfortunately, flow cytometry can be prone to batch effects since blood samples are often collected, prepared and analysed at different times and by different operators. I consider several normalisation techniques to address these issues, using external or within sample controls. The main objective of flow cytometry data analysis is that of identifying different cell types. While this is essentially a clustering problem, currently the most widely applied method is a manual approach which can be inefficient and biased. I investigate ways this process can be automated by fitting mixture models to emulate the manual process. I show that, in the absence of manual gates, data-driven approaches can be applied to detect new cell subsets, not targeted by manual gating, that respond to IL-2 in an in-vitro stimulation experiment. The second type of dataset is generated by qPCR and genotyping arrays, which are applied to DNA from T1D cases and controls to determine whether copy number variation in two Killer Immunoglobulin-like Receptors (KIRs) genes associates with T1D.
I apply normalisation to correct for batch effects between qPCR plates and clustering using mixture models to identify copy number groups.
Supervised clustering is then used to correlate qPCR copy number with SNP data, allowing for association testing in a twenty-fold larger sample size than ever previously considered for KIR genes. Finally, I conclude with what I have learned from applying these methods and how these may be further developed, with special attention to flow cytometry where these remain under utilised. In particular, I discuss how normalisation and clustering relate, and how prior knowledge, when available, can be incorporated into the clustering process.

description: The optimal antiplatelet therapy after patent foramen ovale (PFO)/ atrium septum defect (ASD) closure is a matter of discussion. It is challenging as inter-individual responses to antiplatelet medication vary significantly and common complications are bleeding and ischemic events. In this study, we aimed to analyze the incidence of high on-treatment platelet reactivity (HTPR) to antiplatelet medication in patients undergoing PFO/ASD closure as well as clinical complications and thrombus formation on the occluder during six-month follow-up. This hypothesis generating pilot study was observed, which included 140 patients undergoing PFO/ASD closure. The primary endpoint was pharmacodynamic response to antiplatelet medication. A composite of death, myocardial infarction, bleeding, stroke and thrombus formation on the occluder during six-month follow-up was the secondary endpoint. HTPR to clopidogrel was analyzed using the vasodilator-stimulated protein phosphorylation (VASP), HTPR to aspirin by light-transmission aggregometry (LTA). In 71% of patients HTPR to clopidogrel was detected, HTPR to aspirin in only 4%. We observed 12 complications, 9 bleeding events (including 3 major bleeding events) and 3 transient ischemic attacks. No stroke and no thrombus formation on the occluder occurred. The primary endpoint was not associated with the secondary endpoint. The incidence of HTPR to clopidogrel in PFO/ASD closure patients is very high. Despite this high incidence, no stroke or thrombus formation on the occluder occurred at all. This leads to the hypothesis, that the benefit of additional clopidogrel medication is questionable and has to be investigated in large-scale clinical trials.

description: Let $\mathcal{N} \subset \mathbb{R}^M$ be a smooth simply connected compact manifold without boundary. A rational homotopy subgroup of $π_{N}(\mathcal{N})$ is represented by a homomorphism \[{\rm deg}: π_{N}(\mathcal{N}) \to \mathbb{R}.\] For maps $f: \mathbb{S}^N \to \mathcal{N}$ we give a quantitative estimate of its rational homotopy group element ${\rm deg}([f]) \in \mathbb{R}$ in terms of its fractional Sobolev-norm or Hölder norm. That is, we show that for all $β\in (β_0({\rm deg}),1]$, \[
 |{\rm deg}([f])|\leq C({\rm deg})\, [f]_{W^{β,\frac{N}β}(\mathbb{S}^N)}^{\frac{N+L({\rm deg})}β}, \] and \[
 |{\rm deg}([f])|\leq C({\rm deg})\, [f]_{C^β(\mathbb{S}^N)}^{\frac{N+L({\rm deg})}β}. \] Here $C({\rm deg}) > 0$, $L({\rm deg}) \in \mathbb{N}$, $β_0({\rm deg}) \in (0,1)$ are computable from the rational homotopy group represented by ${\rm deg}$. This extends earlier work by Van Schaftingen and the second author on the Hopf degree to the Novikov's integral representation for rational homotopy groups as developed by Sullivan, Novikov, Hardt and Rivière.

description: Praxiserfahrungen tragen zur Professionalisierung von angehenden Lehrpersonen bei, wie Befunde insbesondere zur Unterrichtskompetenz belegen. Inwiefern die Dauer der Praktika oder deren Strukturmerkmale diese mitbestimmen, ist erst wenig erforscht. Stress- und ressourcentheoretische Zugänge fokussieren nicht nur die Bedeutung der Kompetenz für die Bewältigung von Anforderungen, sondern auch die Bedeutung des Kompetenzerlebens, der Relevanz und der Beanspruchung. Die vorzustellende Studie geht der Frage nach, wie Studierende in unterschiedlichen Praxisphasen die Bewältigung von beruflichen Anforderungen einschätzen. Ergebnisse fördern anforderungsdifferente Einschätzungen der Kompetenz, der Relevanz und der Beanspruchung zutage und zeigen sich in unterschiedlichen Konstellationen, die auf ihr Herausforderungs- und Ressourcenpotenzial hin diskutiert werden.

description: Der Beitrag untersucht die Bedeutung von lerntheoretischen Überzeugungen für die Wahrnehmung von beruflichen Anforderungen, die sich im Kontext der berufspraktischen Studien stellen. Eine clusteranalytische Typenbildung mit Daten von 324 angehenden Lehrpersonen über die Ausprägungen von transmissiven und konstruktivistischen lerntheoretischen Überzeugungen führt zu drei Typen, die sich nicht nur in unterschiedlichen Konstellationen der transmissiven und konstruktivistischen Überzeugungen unterscheiden, sondern auch in der Wahrnehmung und der Deutung von beruflichen Anforderungen. Der im Vergleich zu den anderen Typen stärker transmissiv orientierte Typ fokussiert auf Anforderungen der Rollenfindung und der Klassenführung, beim stärker konstruktivistisch ausgerichteten Typ rückt insbesondere die individuelle Passung des Unterrichts auf die Schülerinnen und Schüler in den Fokus. Der dritte Typ zeichnet sich durch unterdurchschnittlich ausgeprägte Überzeugungen und unterdurchschnittliche Werte der Wahrnehmung von beruflichen Anforderungen aus. Die im Längsschnitt nachgezeichneten typendifferenten Entwicklungen im zweiten, praxisintensiven Studienjahr verweisen auf die Bedeutung lerntheoretischer Überzeugungen für die Professionalisierung angehender Lehrpersonen.

description: Finding unambiguous evidence of non-trivial pairing states is one of the greatest experimental challenges in the field of unconventional superconductivity. Such evidence requires phase-sensitive probes susceptible to the internal structure of the order parameter. We measure the Little-Parks effect to provide clear evidence of an unconventional superconducting order parameter in 4Hb-TaS$_2$. Namely, we find a $π$-shift in the transition-temperature oscillations of rings made of a single crystal. We argue that such an effect can only occur if the underlying order parameter belongs to a two-dimensional representation, in other words there are two degenerate order parameters right at the transition. Additionally, we show that $T_c$ is enhanced as a function of the out-of-plane field when a constant in-plane field is applied. Such an increase is consistent with a chiral state, which again, in general only emerges from a two-component order parameter. In combination with previous experiments, our results strongly indicate that 4Hb-TaS$_2$ indeed realizes a chiral superconductor.

description: This is the second of four issues in the special series investigating Contemporary Educator Movements: Transforming Unions, Schools, and Society in North America. This issue focuses on the “red” statewide K12 education strikes in the United States in the spring of 2018, contributing substantive analyses of the relatively understudied contexts of the walkouts for scholars and organizers. Together, the pieces in this issue suggest the importance of attending to the unique and deeply contested political geographies of the nation’s more rural regions and the significance of these regions to contemporary educator struggles.

Efficient Wrong-Way Risk Modelling for Funding Valuation Adjustments

description: Wrong-Way Risk (WWR) is an important component in Funding Valuation Adjustment (FVA) modelling. Yet, the standard assumption is independence between market risks and the counterparty defaults and funding costs. This typical industrial setting is our point of departure, where we aim to assess the impact of WWR without running a full Monte Carlo simulation with all credit and funding processes. We propose to split the exposure profile into two parts: an independent and a WWR-driven part. For the former, exposures can be re-used from the standard xVA calculation. We express the second part of the exposure profile in terms of the stochastic drivers and approximate these by a common Gaussian stochastic factor. Within the affine setting, the proposed approximation is generic, is an add-on to the existing xVA calculations and provides an efficient and robust way to include WWR in FVA modelling. Case studies for an interest rate swap and a representative multi-currency portfolio of swaps illustrate that the approximation method is applicable in a practical setting. We analyze the approximation error and use the approximation to compute WWR sensitivities, which are needed for risk management. The approach is equally applicable to other metrics such as Credit Valuation Adjustment.
