Synthesis

description: Molecules that disrupt microtubule dynamics are widely used in human medicine to treat cancer. Leiodermatolide A is an antimitotic marine macrolide that was isolated in 2008 from crude extracts of a deep water lithistid sponge of the genus Leiodermatium. In a panel of human cancer cell lines, leiodermatolide A exhibited potent antiproliferative effects, selectively perturbing tubulin dynamics at nM concentrations through a novel mechanism of action: while abnormal spindle formation is observed at nM concentrations in two different cancer cell lines, purified tubulin was unaffected in vitro at much higher concentrations. As leiodermatolide A cannot be obtained in sufficient quantities from its natural source, we have launched a campaign to prepare leiodermatolide A via de novo chemical synthesis using novel catalytic carbon-carbon bond forming reactions developed in our laboratory. These efforts have resulted in the shortest total synthesis of leiodermatolide A reported to date, enabling more detailed explorations into its mechanism of action.

description: Using evolutionary crystal structure prediction algorithm USPEX, we identify the compositions and crystal structures of stable compounds in the Fe-S system at pressures in the range 100-400 GPa. We find that at pressures of the Earth's solid inner core (330-364 GPa) two compounds are stable - Fe2S and FeS. In equilibrium with iron, only Fe2S can exist in the inner core. Using the equation of state of Fe2S, we find that in order to reproduce the density of the inner core by adding sulfur alone, 10.6-13.7 mol.% (6.4-8.4 wt.%) sulfur is needed. Analogous calculation for silicon (where the only stable compound at inner core pressures is FeSi) reproduces the density of the inner core with 9.0-11.8 mol.% (4.8-6.3 wt.%) silicon. In both cases, a virtually identical mean atomic mass M in the range 52.6-53.3 results for in the inner core, which is much higher than M = 49.3 determined for the inner core from Birch's law. For oxygen (where the relevant stable oxide at conditions of the inner core is Fe2O) we find the matching concentration in the range 13.2-17.2 mol.% (4.2-5.6 wt.%), which corresponds to M in the range 49.0-50.6. Combining our results and previous works, we find that inner core density and M can be explained by only four models (in atomic %): (a) 86%(Fe+Ni) + 14%C, (b) 84%(Fe+Ni) + 16%O, (c) 84%(Fe+Ni) + 7%S + 9%H, (d) 85%(Fe+Ni) + 6%Si + 9%H, and some of their linear combinations (primarly, models (c) and (d)).

description: Extending work by Gies and Karbstein on the Euler-Heisenberg Lagrangian, it has recently been shown that the one-loop propagator of a charged scalar particle in a constant electromagnetic field has a one-particle reducible contribution in addition to the well-studied irreducible one. Here we further generalize this result to the spinor case, and find the same relation between the reducible term, the tree-level propagator and the one-loop Euler-Heisenberg Lagrangian as in the scalar case. Our demonstration uses a novel worldline path integral representation of the photon-dressed spinor propagator in a constant electromagnetic field background.

High-redshift

description: Far-infrared and (sub)millimeter-bright galaxies are relatively rare in the local Universe, but known to be common at earlier epochs having been observed to dominate the cosmic star formation rate beyond a lookback time of eight billion years, i.e. redshift (z) >1. These systems are distinguished by their high dust mass, as well as the powerful bursts of star formation they undergo, and are capable of forming stars at one thousand times the rate of the Milky Way. In this doctoral thesis, I utilize optical through radio observations to determine the redshifts and physical properties of extreme starbursts, known as dusty star-forming galaxies (DSFGs), at two distinct epochs. I first examine DSFGs around the peak of cosmic star formation at z [approximately equal to] 2, a.k.a. cosmic noon, at which time they contribute roughly half of the Universe’s total star formation. Through this study I ascertain a link between morphology and radio luminosity and the importance of major mergers and interactions in triggering the DSFG phase of galaxy evolution. The sample of sources is selected from the Super-Cluster Assisted Shear Survey (SuperCLASS) and I present a multi-band photometric catalog I assembled covering the 2deg² survey. This catalog includes optical/mid-infrared photometry and photometric redshifts derived from fitting stellar population synthesis and AGN models to over 375,000 sources. Pushing on to even earlier times, within the first two billion years of the Universe (z>3), I then present a focused analysis of two z [approximately equal to] 4 DSFGs observed at 2-millimeters with the Atacama Large Millimeter/submillimeter Array (ALMA) as part of the Mapping Obscuration to Reionization with ALMA (MORA) survey. The physical characteristics of these two galaxies are consistent with a class of extremely dust-obscured, optically/near-infrared (OIR) invisible DSFGs in the literature. Ultimately, I provide evidence supporting the current theory that “OIR-dark” DSFGs are the progenitors of recently discovered 3

description: The use of flat plates (i.e., slabs without capitals, drop panels, or supporting beams) in reinforced concrete (RC) building construction has become widespread throughout much of the world. In comparison to other slab types, RC flat plates are often more efficient from a construction standpoint due to their simplified geometries and reduced formwork requirements. However, the complexities of the load transfer mechanisms developed in these systems are still not fully understood. The research presented in this dissertation was aimed toward expanding the current knowledge regarding the punching shear behavior of RC flat plates by investigating the response of slab-column connections under highly-controlled two-way shear loading conditions. The influence of through-thickness shear reinforcement, longitudinal reinforcement ratio, and connection region loading conditions have been investigated and presented in three technical papers which summarize the key findings obtained from the testing of twelve full-scale connection specimens and the supplemental analytical efforts. In the first paper, the performance of RC flat plates employing an alternative shear reinforcement system consisting of inclined deformed reinforcing bars is compared to slabs constructed with conventional reinforcement. The findings showed that premature failures attributed to inadequate reinforcement anchorage controlled the performance of the slabs and limited the benefit provided by the inclined stirrups. In the second paper, the punching shear performance of headed stud reinforced slabs that were constructed with either a cruciform or a radial stud layout, was investigated. Results showed that both shear stud layouts improved the shear-resisting behaviors of the slabs and produced structural responses that were comparable in nearly all aspects. In the third paper, slabs subjected to different sectional loading conditions were examined to assess the influence of loading composition on flat plate shear resisting performance. Experimental work was complimented with numerical analyses and the results indicated that the punching shear response of flat plates is greatly influenced by flexural demands. Further, it was found that the loads experienced by slab specimens tested using common procedures may not be representative of loading conditions experienced by flat plates in service.

Exactly soluble local bosonic cocycle models, statistical transmutation, and simplest time-reversal symmetric topological orders in 3+1D

description: We propose a generic construction of exactly soluble \emph{local bosonic models} that realize various topological orders with gappable boundaries. In particular, we construct an exactly soluble bosonic model that realizes a 3+1D $Z_2$ gauge theory with emergent fermionic Kramer doublet. We show that the emergence of such a fermion will cause the nucleation of certain topological excitations in space-time without pin$^+$ structure. The exactly soluble model also leads to a statistical transmutation in 3+1D. In addition, we construct exactly soluble bosonic models that realize 2 types of time-reversal symmetry enriched $Z_2$-topological orders in 2+1D, and 20 types of simplest time-reversal symmetry enriched topological (SET) orders which have only one non-trivial point-like and string-like topological excitations. Many physical properties of those topological states are calculated using the exactly soluble models. We find that some time-reversal SET orders have point-like excitations that carry Kramer doublet -- a fractionalized time-reversal symmetry. We also find that some $Z_2$ SET orders have string-like excitations that carry anomalous (non-on-site) $Z_2$ symmetry, which can be viewed as a fractionalization of $Z_2$ symmetry on strings. Our construction is based on cochains and cocycles in algebraic topology, which is very versatile. In principle, it can also realize emergent topological field theory beyond the twisted gauge theory.

Self-Organizing Systems in Planetary Physics: Harmonic Resonances of Planet and Moon Orbits

description: The geometric arrangement of planet and moon orbits into a regularly spaced pattern of distances is the result of a self-organizing system. The positive feedback mechanism that operates a self-organizing system is accomplished by harmonic orbit resonances, leading to long-term stable planet and moon orbits in solar or stellar systems. The distance pattern of planets was originally described by the empirical Titius-Bode law, and by a generalized version with a constant geometric progression factor (corresponding to logarithmic spacing). We find that the orbital periods $T_i$ and planet distances $R_i$ from the Sun are not consistent with logarithmic spacing, but rather follow the quantized scaling $(R_{i+1}/R_i) = (T_{i+1}/T_i)^{2/3} = (H_{i+1}/H_i)^{2/3}$, where the harmonic ratios are given by five dominant resonances, namely $(H_{i+1} : H_{i}) = (3:2), (5:3), (2:1), (5:2), (3:1)$. We find that the orbital period ratios tend to follow the quantized harmonic ratios in increasing order. We apply this harmonic orbit resonance model to the planets and moons in our solar system, and to the exo-planets of 55 Cnc and HD 10180 planetary systems. The model allows us a prediction of missing planets in each planetary system, based on the quasi-regular self-organizing pattern of harmonic orbit resonance zones. We predict 7 (and 4) missing exo-planets around the star 55 Cnc (and HD 10180). The accuracy of the predicted planet and moon distances amounts to a few percents. All analyzed systems are found to have $\approx 10$ resonant zones that can be occupied with planets (or moons) in long-term stable orbits.

Which policies and practices influence vertical transfer and baccalaureate attainment among community college entrants? : a multi-level analysis

description: Community colleges serve many roles, but perhaps their most important is as a stepping-stone to a four-year institution. Unfortunately, over the past few decades, baccalaureate attainment for those beginning at a community college has declined. This waning has sparked an effort by legislators, community college leaders, and educational researchers to identify policies and practices to improve these outcomes. This study contributes to this by using a nationally representative sample of first-time college students to explore which factors at the student, institution, and state level are associated with vertical transfer and baccalaureate attainment. Results from a multi-level model illustrate that variables at all three analysis levels were significantly related to vertical transfer or baccalaureate attainment. At the student level, meeting with an academic advisor, staying continuously enrolled as a full-time student, working part-time or less, and choosing a transfer-oriented major were positively associated with vertical transfer or baccalaureate attainment, while transferring horizontally (to another institution at the same level) was negatively related to baccalaureate attainment. At the institution level, the local unemployment rate was positively related and percent Pell recipients was negatively related to these outcomes. Cooperative agreements and statewide articulation guides were positively related to vertical transfer or baccalaureate attainment at the state level. The results offer insights that may be useful to higher education stakeholders and policymakers. I conclude with considerations for policy and practice, as well as for future research.

description: The ever-increasing presence of autonomy in our lives calls for immediate and significant investment in the development of effective, safe, and trustworthy autonomous systems. In the real world, these systems need to make sequential decisions in complex and dynamic environments while interacting with human decision-makers. Furthermore, they may have access to an immense amount of heterogeneous data, which requires them to be selective about what data to gather due to their limited perception capability. I focus on developing theory and algorithms that enable autonomous agents to operate in our complex world. The algorithms I develop address the following fundamental challenges: 1) active identification and gathering of actionable information from large-scale, multi-modal, and noisy data, 2) planning and learning based on partial and evolving knowledge, in real time and with theoretical performance guarantees, and 3) interacting and collaborating with humans in a trustworthy manner. Given the multidimensionality of these challenges, the proposed algorithms rely on drawing new connections between the fields of control, learning, formal methods, and information theory. The first part of my contributions entails introducing joint active perception and planning algorithms in unknown or uncertain environments so that a decision-maker can efficiently find the most relevant data for its task. In the second part of my contributions, I propose online planning algorithms capable of integrating runtime data, from the environment or a human user, into sequential decision-making reliably. The third part of my contributions presents planning algorithms for tasks described in temporal logic languages such that their outputs are interpretable by human users. The proposed interdisciplinary ideas enhance the efficiency, reliability, and interpretability of automated sequential decision-making — taking a step toward designing competent, autonomous systems that co-exist with humans.

description: The purpose of the study is to reveal instructors’ design strategies regarding dialogue and structure in asynchronous online courses, uncover how those designs were received by students, and the predictive effects of course design and student motivation on student learning. A sample of 287 college students and two online course instructors participated in the study. The findings showed that course formality and flexibility indirectly predicted student perceived learning outcomes through the roles of subject specific task values, subject specific emotional cost, online learning self-efficacy, and online learning task values. Dialogue with instructors and classmates did not significantly predict student perceived learning outcomes. Results of student and instructor interviews supported the quantitative results and revealed that formality and flexibility of asynchronous online courses were highly appreciated by students, whereas the dialogic practices instructors used received mixed feedback. These findings suggest that course design is critical in asynchronous online learning, and it has positive impact on students’ motivation, emotional well-being, and student learning outcomes. Practical implications for designing asynchronous online courses are discussed in the paper.

description: It is well-established that many physical properties of DNA at sufficiently long length scales can be understood by means of simple polymer models. One of the most widely used elasticity models for DNA is the twistable worm-like chain (TWLC), which describes the double helix as a continuous elastic rod with bending and torsional stiffness. An extension of the TWLC, which has recently received some attention, is the model by Marko and Siggia, who introduced an additional twist-bend coupling, expected to arise from the groove asymmetry. By performing computer simulations of two available versions of oxDNA, a coarse-grained model of nucleic acids, we investigate the microscopic origin of twist-bend coupling. We show that this interaction is negligible in the oxDNA version with symmetric grooves, while it appears in the oxDNA version with asymmetric grooves. Our analysis is based on the calculation of the covariance matrix of equilibrium deformations, from which the stiffness parameters are obtained. The estimated twist-bend coupling coefficient from oxDNA simulations is $G=30\pm1$~nm. The groove asymmetry induces a novel twist length scale and an associated renormalized twist stiffness $κ_{\rm t} \approx 80$~nm, which is different from the intrinsic torsional stiffness $C \approx 110$~nm. This naturally explains the large variations on experimental estimates of the intrinsic stiffness performed in the past.

description: Geopolitics focuses on political power in relation to geographic space. Interactions among world countries have been widely studied at various scales, observing economic exchanges, world history or international politics among others. This work exhibits the potential of Wikipedia mining for such studies. Indeed, Wikipedia stores valuable fine-grained dependencies among countries by linking webpages together for diverse types of interactions (not only related to economical, political or historical facts). We mine herein the Wikipedia networks of several language editions using the recently proposed method of reduced Google matrix analysis. This approach allows to establish direct and hidden links between a subset of nodes that belong to a much larger directed network. Our study concentrates on 40 major countries chosen worldwide. Our aim is to offer a multicultural perspective on their interactions by comparing networks extracted from five different Wikipedia language editions, emphasizing English, Russian and Arabic ones. We demonstrate that this approach allows to recover meaningful direct and hidden links among the 40 countries of interest.

description: We investigate the observational constraints on an interacting vacuum energy scenario with two different neutrino schemes (with and without a sterile neutrino) using the most recent data from CMB temperature and polarization anisotropy, baryon acoustic oscillations (BAO), type Ia supernovae from JLA sample and structure growth inferred from cluster counts. We find that inclusion of the galaxy clusters data with the minimal data combination CMB + BAO + JLA suggests an interaction in the dark sector, implying the decay of dark matter particles into dark energy, since the constraints obtained by including the galaxy clusters data yield a non-null and negative coupling parameter between the dark components at 99\% confidence level. We deduce that the current tensions on the parameters $H_0$ and $σ_8$ can be alleviated within the framework of the interacting as well as non-interacting vacuum energy models with sterile neutrinos.

description: We present an in-depth many-body investigation of the so-called mesoscopic molecular ions that can build-up when an ion is immersed into an atomic Bose-Einstein condensate in one dimension. To this end, we employ the Multi-Layer Multi-Configuration Time-Dependent Hartree method for Mixtures of ultracold bosonic species for solving the underlying many-body Schrödinger equation. This enables us to unravel the actual structure of such massive charged molecules from a microscopic perspective. Laying out their phase diagram with respect to atom number and interatomic interaction strength, we determine the maximal number of atoms bound to the ion and reveal spatial densities and molecular properties. Interestingly, we observe a strong interaction-induced localization, especially for the ion, that we explain by the generation of a large effective mass, similarly to ions in liquid Helium. Finally, we predict the dynamical response of the ion to small perturbations. Our results provide clear evidence for the importance of quantum correlations, as we demonstrate by benchmarking them with wave function ansatz classes employed in the literature.

The most important physical variable to characterize hot QCD is the Polyakov loop, which is an approximate order parameter for quark deconfinement in a hot gluonic medium. Additionally to its role as an order parameter, the Polyakov loop has rich physical contents in both perturbative and non-perturbative sectors. This review covers a wide range of subjects associated with the Polyakov loop from topological defects in hot QCD to model building with coupling to the Polyakov loop.

description: The microscopic nature of the XYZ states remains an unsettled topic. We show how a thorough amplitude analysis of the data can help constraining models of these states. Specifically, we consider the case of the Zc(3900) peak and discuss possible scenarios of a QCD state, virtual state, or a kinematical enhancement. We conclude that current data are not precise enough to distinguish between these hypotheses, however, the method we propose, when applied to the forthcoming high-statistics measurements should shed light on the nature of these exotic enhancements.

description: The Standard Model (SM) is inadequate to explain the origin of tiny neutrino masses, the dark matter (DM) relic abundance and also the baryon asymmetry of the Universe. In this work to address all the three puzzles, we extend the SM by a local U$(1)_{\rm B-L}$ gauge symmetry, three right-handed (RH) neutrinos for the cancellation of gauge anomalies and two complex scalars having nonzero U$(1)_{\rm B-L}$ charges. All the newly added particles become massive after the breaking of U$(1)_{\rm B-L}$ symmetry by the vacuum expectation value (VEV) of one of the scalar fields $ϕ_H$. The other scalar field $ϕ_{DM}$, which does not have any VEV, becomes automatically stable and can be a viable DM candidate. Neutrino masses are generated using Type-I seesaw mechanism while the required lepton asymmetry to reproduce the observed baryon asymmetry, can be attained from the CP violating out of equilibrium decays of RH neutrinos in TeV scale. More importantly within this framework, we have studied in detail the production of DM via freeze-in mechanism considering all possible annihilation and decay processes. Finally, we find a situation when DM is dominantly produced from the annihilation of RH neutrinos, which are at the same time also responsible for neutrino mass generation and leptogenesis.

description:
Minerals in beautiful colors and shapes still attract visitors to museums. Whereas in the past it was hobby collectors, today it is also interested people who want to find out more. Dusty showcases filled with systematically arranged minerals are no longer in demand. Current topics from science do, especially if they are related to everyday life. The exhibition about minerals in Smartphones in the Würzburg University Mineralogical Museum attracted a large number of visitors from different age and professional groups. Exhibitions with artists reach a different group of visitors. Accompanying the exhibitions, a museum educational program is offered with original illustrative material and models as well as presentations on current scientific results, prepared in an understandable way. As part of the museum's public relations work, school classes are among the most important visitors. Enthusiastic pupils are multipliers and our future students. The aim is to arouse children’s curiosity about science. A visit to the museum serves as an ideal supplement to the curriculum-related lessons at all types of schools. Symmetry operations in the primary school mathematics curriculum can be supplemented very well by symmetry exercises on original crystals and by making crystal models in the museum. At Bavarian secondary schools, the subject of geology is offered as an alternative curriculum in the upper grades. The Mineralogical Museum has been a training partner of these schools for many years. In the teaching-learning laboratory, the students get to know the various geoscientific working methods and identify minerals and rocks accompanied by students.

description: 2D materials provide a platform for strong light--matter interactions, creating wide-ranging design opportunities via new-material discoveries and new methods for geometrical structuring. We derive general upper bounds to the strength of such light--matter interactions, given only the optical conductivity of the material, including spatial nonlocality, and otherwise independent of shape and configuration. Our material figure of merit shows that highly doped graphene is an optimal material at infrared frequencies, whereas single-atomic-layer silver is optimal in the visible. For quantities ranging from absorption and scattering to near-field spontaneous-emission enhancements and radiative heat transfer, we consider canonical geometrical structures and show that in certain cases the bounds can be approached, while in others there may be significant opportunity for design improvement. The bounds can encourage systematic improvements in the design of ultrathin broadband absorbers, 2D antennas, and near-field energy harvesters.

description: Most people simultaneously belong to several distinct social networks, in which their relations can be different. They have opinions about certain topics, which they share and spread on these networks, and are influenced by the opinions of other persons. In this paper, we build upon this observation to propose a new nodal centrality measure for multiplex networks. Our measure, called Opinion centrality, is based on a stochastic model representing opinion propagation dynamics in such a network. We formulate an optimization problem consisting in maximizing the opinion of the whole network when controlling an external influence able to affect each node individually. We find a mathematical closed form of this problem, and use its solution to derive our centrality measure. According to the opinion centrality, the more a node is worth investing external influence, and the more it is central. We perform an empirical study of the proposed centrality over a toy network, as well as a collection of real-world networks. Our measure is generally negatively correlated with existing multiplex centrality measures, and highlights different types of nodes, accordingly to its definition.

Near-field speckle-scanning-based X-ray tomography

description: We previously demonstrated near-field speckle scanning based x-ray imaging to be an easy-to-implement phase sensing method capable of providing both high sensitivity and high resolution. Yet, this performance combination could only be achieved at the cost of a significant number of sample exposures and of extensive data acquisition time, thus tempering its implementation for tomography applications. Herein, we show ways of drastically lowering the number of exposures for the speckle scanning method to become attractive for computed tomography (CT) imaging. As the method presented can cope with a high divergence beam, it is also expected to attract the attention of the laboratory sources community.

On the Role of English in the post-Brexit European Union
Creators: name: Herbert, Manfred
Publisher: name: International Journal of Language & Law (JLL)
Year: 2023

description: This paper examines the role of English in the post-Brexit EU through three lenses. From a legal perspective, the role of English has not been changed by Brexit. English remains one of the 24 Treaty languages, official languages and working languages in the EU. The removal of English, which could only be decided unanimously by the Council of the EU, has never been seriously considered. From an empirical perspective, there is evidence that English is the dominant working language in the EU institutions. In this respect, there are no indications of any change after Brexit, even if some call for a reduction in its primacy. From a moral perspective, Brexit should strengthen the role of English at the levels of working languages and transnational communication for two reasons: first, because English is an almost neutral language after Brexit, which significantly reduces injustices associated with its use during the UK’s EU membership, and second, because it can be expected that “Euro-English” will become even more autonomous and can be regarded as the Europeans’ own language.

description: We revisit the so-called "Geodesic Witten Diagrams" (GWDs) \cite{ScalarGWD}, proposed to be the holographic dual configuration of scalar conformal partial waves, from the perspectives of CFT operator product expansions. To this end, we explicitly consider three point GWDs which are natural building blocks of all possible four point GWDs, discuss their gluing procedure through integration over spectral parameter, and this leads us to a direct identification with the integral representation of CFT conformal partial waves. As a main application of this general construction, we consider the holographic dual of the conformal partial waves for external primary operators with spins. Moreover, we consider the closely related "split representation" for the bulk to bulk spinning propagator, to demonstrate how ordinary scalar Witten diagram with arbitrary spin exchange, can be systematically decomposed into scalar GWDs. We also discuss how to generalize to spinning cases.

description: The recent discovery of excellent thermoelectric properties and topological surface states in SnTe-based compounds has attracted extensive attention in various research areas. Indium doped SnTe is of particular interest because, depending on the doping level, it can either generate resonant states in the bulk valence band leading to enhanced thermoelectric properties, or induce superconductivity that coexists with topological states. Here we report on the vapor deposition of In-doped SnTe nanowires and the study of their surface oxidation and thermoelectric properties. The nanowire growth is assisted by Au catalysts, and their morphologies vary as a function of substrate position and temperature. Transmission electron microscopy characterization reveals the formation of amorphous surface in single crystalline nanowires. X-ray photoelectron spectroscopy studies suggest that the nanowire surface is composed of In2O3, SnO2, Te and TeO2 which can be readily removed by argon ion sputtering. Exposure of the cleaned nanowires to atmosphere yields rapid oxidation of the surface within only one minute. Characterizations of electrical conductivity σ, thermopower S, and thermal conductivity \k{appa} were performed on the same In-doped nanowire which shows suppressed σ and \k{appa} but enhanced S yielding an improved thermoelectric figure of merit ZT than the undoped SnTe.
