title: Literarische Zensur in Kuba
Creators: name: Kirchmeier, Corinna
Year: 2010

description: Diese Arbeit beschäftigt sich mit dem Phänomen der Zensur in Kuba, beginnend mit der Zeit nach der Kubanischen Revolution 1959 und der Machtübernahme Fidel Castros. Hierbei soll die Vorgehensweise der Autoritäten dokumentiert werden, welche durch gezielte Maßnahmen - wie Veröffentlichungsverbot, Streichungen und Kürzungen der Texte oder sogar Verfolgung und Arrest - versuchen, sämtliche Aspekte des Lebens der kubanischen Bevölkerung zu kontrollieren. So stehen die meisten Künstler und Intellektuellen unter ständiger Beobachtung und Überwachung des Staates. Mit Fidel Castros Ansprache im Jahr 1961 in der Nationalbibliothek wurden die Rahmenbedingungen für die kubanische Kulturpolitik festgelegt und ein Kurs vorgegeben, an dem sich Kubas Schriftsteller und Künstler zu orientieren hatten. Grundsätzlich sollten diese für die Ziele der Revolution eintreten sowie die Ideale des Kommunismus in ihren Werken vertreten. Der Inhalt eines Romans musste an der sozialistischen Realität orientiert sein, die Regierung durfte weder direkt angegriffen noch durfte über Gesinnungen berichtet werden, die sich gegen die Ideen der Revolution stellten, wie zum Beispiel kapitalistische Ansichten oder Homosexualität. Diejenigen, welche aus verschiedenen Gründen nicht diesem Credo folgen konnten oder wollten, wurden systematisch diskriminiert und so zum Schweigen gebracht oder ins Exil getrieben. Reinaldo Arenas und Guillermo Cabrera Infante sind zwei Autoren, die von der Regierung konterrevolutionärer Taten beschuldigt wurden und deren Werke in Kuba nicht veröffentlicht werden durften. Beide waren anfangs Unterstützer der kubanischen Revolution, doch wie so viele andere Intellektuelle, die durch enttäuschte Erwartungen zu Kritikern wurden, stellten sie sich bald gegen das Regime.

description: First-principles calculations of electron interactions in materials have seen rapid progress in recent years, with electron-phonon (e-ph) interactions being a prime example. However, these techniques use large matrices encoding the interactions on dense momentum grids, which reduces computational efficiency and obscures interpretability. For e-ph interactions, existing interpolation techniques leverage locality in real space, but the high dimensionality of the data remains a bottleneck to balance cost and accuracy. Here we show an efficient way to compress e-ph interactions based on singular value decomposition (SVD), a widely used matrix / image compression technique. Leveraging (un)constrained SVD methods, we accurately predict material properties related to e-ph interactions - including charge mobility, spin relaxation times, band renormalization, and superconducting critical temperature - while using only a small fraction (1-2%) of the interaction data. These findings unveil the hidden low-dimensional nature of e-ph interactions. Furthermore, they accelerate state-of-the-art first-principles e-ph calculations by about two orders of magnitudes without sacrificing accuracy. Our Pareto-optimal parametrization of e-ph interactions can be readily generalized to electron-electron and electron-defect interactions, as well as to other couplings, advancing quantitative studies of condensed matter.

description: We explore the Quantum Chromodynamics (QCD) phase diagram's complexities, including quark deconfinement transitions, liquid-gas phase changes, and critical points, using the chiral mean-field (CMF) model that is able to capture all these features. We introduce a vector meson renormalization within the CMF framework, enabling precise adjustments of meson masses and coupling strengths related to vector meson interactions. Performing a new fit to the deconfinement potential, we are able to replicate recent lattice QCD results, low energy nuclear physics properties, neutron star observational data, and key phase diagram features as per modern constraints. This approach enhances our understanding of vector mesons' roles in mediating nuclear interactions and their impact on the equation of state, contributing to a more comprehensive understanding of the QCD phase diagram and its implications for nuclear and astrophysical phenomena.

Diesem Aspekt wird sowohl in pragmatischer wie auch in programmatischer Hinsicht nachgespürt. Des Weiteren wird der historische rote Faden innerhalb der (theologischen) Bibelübersetzung skizziert, und aufgezeigt, wie diese zunächst von der Übersetzung als von Gott inspirierte Tätigkeit ausging, sich im Weiteren jedoch auch zur philologischen Methode weiterentwickelte, sodass Bibelübersetzung heute im Allgemeinen als Kombination von Inspiration und Philologie verstanden wird. Darüber hinaus werden die Bemühungen der letzten Jahrzehnte aufgezeigt, Errungenschaften der Übersetzungswissenschaft für die Bibelübersetzung heranzuziehen, um so die Qualität der einzelnen Übersetzungen noch zu erhöhen. Abschließend kommt es zum Vergleich einzelner Bibelübersetzungen des deutschsprachigen Neuen Testaments, anhand ausgewählter Bibelstellen.

description: Strongly correlated quantum matter -- such as interacting electron systems or interacting quantum fluids -- possesses properties that cannot be understood in terms of linear fluctuations and free quasi-particles. Quantum fluctuations in these systems are indeed large and generically exhibit non-Gaussian statistics -- a property captured only by inspecting high-order correlations, whose quantitative reconstruction poses a formidable challenge to both experiments and theory alike. A prime example of correlated quantum matter is the strongly interacting Bose fluid, realized by superfluid Helium and, more recently, ultra-cold atoms. Here, we experimentally study interacting Bose gases from the weakly to the strongly interacting regime through single-atom-resolved correlations in momentum space. We observe that the Bogoliubov pairing among modes of opposite momenta, emblematic of the weakly interacting regime, is suppressed as interactions become stronger. This departure from the predictions of Bogoliubov theory signals the onset of the strongly correlated regime, as confirmed by numerical simulations that highlight the role of non-linear quantum fluctuations in our system. Additionally, our measurements unveil a non-zero four-operator cumulant at even stronger interactions, which is a direct signature of non-Gaussian correlations. These results shed light on the emergence and physical origin of non-Gaussian correlations in ensembles of interacting bosons.

description: The notion of Vasconcelos invariant, known in the literature as v-number, of a homogeneous ideal in a polynomial ring over a field was introduced in 2020 to study the asymptotic behaviour of the minimum distance of projective Reed-Muller type codes. We initiate the study of this invariant for graded modules. Let $R$ be a Noetherian $\mathbb{N}$-graded ring, and $M$ be a finitely generated graded $R$-module. The v-number $v(M)$ can be defined as the least possible degree of a homogeneous element $x$ of $M$ for which $(0:_Rx)$ is a prime ideal of $R$. For a homogeneous ideal $I$ of $R$, we mainly prove that $v(I^nM)$ and $v(I^nM/I^{n+1}M)$ are eventually linear functions of $n$. In addition, if $(0:_M I)=0$, then $v(M/I^{n}M)$ is also eventually linear with the same leading coefficient as that of $v(I^nM/I^{n+1}M)$. These leading coefficients are described explicitly. The result on the linearity of $v(M/I^{n}M)$ considerably strengthens a recent result of Conca which was shown when $R$ is a domain and $M=R$, and Ficarra-Sgroi where the polynomial case is treated.

Non-convex uadratically constrained quadratic program
Robust Optimiziation

description: As an important branch of operation research, nonlinear programming (NLP) has evolved considerably in the last few decades and provides powerful tools in engineering. In this dissertation, we mainly focus on applying optimization techniques on solving the Optimal Power Flow(OPF) problem in the power grid, which is generally nonlinear, nonconvex, and computational expensive with large system size.
description: We start by addressing the problem of globally solving nonconvex mixed-integer quadratically constrained programming (MIQCP). By using the compact lifted mixed-integer formulation to relax the square function in a piecewise manner, we construct the compact disjunctive approximation (CDA) to approximate the nonconvex MIQCP to arbitrary precision. Further, we refine the state-of-art approaches exploiting semidefiniteness and combine it with the CDA scheme to construct a global solver to approximate the alternating current OPF problem.
description: Considering the uncertainty brought by the widespread usage of renewable energy, we work on solving the quadratically-constrained robust optimization problem. We construct an explicit region based on Brouwer's theorem such that one can compute the next iterate by optimizing over this set. A sequence of the robust convex optimization problem is formulated which can be solved by utilizing the Sequential Robust Convex Optimization Algorithm (SRCOA) with the cutting-plane techniques as a subroutine. We proposed the subroutine with the exact and approximate oracles separately in the pessimization step. By providing the convergence guarantee of the subroutines, we further show the recursive feasibility, infinite descent, and convergence of SRCOA.
description: To deal with the large-scale power distribution system, we present the convergence analysis of a novel distributed real-time approach named Equivalence of Network-based Distributed Controller for Optimization (ENDiCO) to achieve the network-level optimal solutions in fewer time steps by exploring the radial topology of the network based on the equivalence assumption. For the proposed nonlinear model, we show the local convergence guarantees for ENDiCO through the second-order sufficient condition and verify the convergence numerically for specific parameter values that are commonly used in practice. Meanwhile, we model the formulation of the subsystem over time and provide sufficient conditions to guarantee the convergence performance at some specific time step t.

description: Multiplexed operations and extended coherent control over multiple trapping sites are fundamental requirements for a trapped-ion processor in a large scale architecture. Here we demonstrate these building blocks using a surface-electrode trap with integrated photonic components which are scalable to larger numbers of zones. We implement a Ramsey sequence using the integrated light in two zones, separated by 375 $μ$m, performing transport of the ion from one zone to the other in 200 $μ$s between pulses. In order to achieve low motional excitation during transport, we developed techniques to measure and mitigate the effect of the exposed dielectric surfaces used to deliver the integrated light to the ion. We also demonstrate simultaneous control of two ions in separate zones with low optical crosstalk, and use this to perform simultaneous spectroscopy to correlate field noise between the two sites. Our work demonstrates the first transport and coherent multi-zone operations in integrated photonic ion trap systems, forming the basis for further scaling in the trapped-ion QCCD architecture.

description: This paper, the fourth part of a series of papers on the arithmetic average (AA) density fusion approach and its application for target tracking, addresses the intricate challenge of distributed heterogeneous multisensor multitarget tracking, where each inter-connected sensor operates a probability hypothesis density (PHD) filter, a multiple Bernoulli (MB) filter or a labeled MB (LMB) filter and they cooperate with each other via information fusion. Earlier papers in this series have proven that the proper AA fusion of these filters is all exactly built on averaging their respective unlabeled/labeled PHDs. Based on this finding, two PHD-AA fusion approaches are proposed via variational minimization of the upper bound of the Kullback-Leibler divergence between the local and multi-filter averaged PHDs subject to cardinality consensus based on the Gaussian mixture implementation, enabling heterogeneous filter cooperation. One focuses solely on fitting the weights of the local Gaussian components (L-GCs), while the other simultaneously fits all the parameters of the L-GCs at each sensor, both seeking average consensus on the unlabeled PHD, irrespective of the specific posterior form of the local filters. For the distributed peer-to-peer communication, both the classic consensus and flooding paradigms have been investigated. Simulations have demonstrated the effectiveness and flexibility of the proposed approaches in both homogeneous and heterogeneous scenarios.

description: Beam displacement measurements are widely used in optical sensing and communications; however, their performance is affected by numerous intrinsic and extrinsic factors including beam profile, propagation loss, and receiver architecture. Here we present a framework for designing a classically optimal beam displacement transceiver, using quantum estimation theory. We consider the canonical task of estimating the position of a diffraction-limited laser beam after passing through an apertured volume characterized by Fresnel-number product DF. As a rule of thumb, higher-order Gaussian modes provide more information about beam displacement, but are more sensitive to loss. Applying quantum Fisher information, we design mode combinations that optimally leverage this trade-off, and show that a greater than 10-fold improvement in precision is possible, relative to the fundamental mode, for a practically relevant DF = 100. We also show that this improvement is realizable with a variety of practical receiver architectures. Our findings extend previous works on lossless transceivers, may have immediate impact on applications such as atomic force microscopy and near-field optical communication, and pave the way towards globally optimal transceivers using non-classical laser fields.

description: Organic solar cells (OSCs) are promising as printable and massively scalable solar energy sources. The highest performing device architecture, the bulk heterojunction (BHJ) is constructed by printing a single active layer consisting of a mixture of organic electron donating and accepting molecules, and its efficiencies are approaching 20%. The charge generation and recombination processes in BHJ active layers govern device performance in OSCs but separating these two processes is difficult due to the morphological complexity. Time delay collection field (TDCF) is an advanced charge extraction technique that quantitatively separates charge generation and recombination processes at operation-relevant fields, but device capacitances limit the effectiveness of this technique. We introduce an altered experiment, ‘Overpulse TDCF,’ that overcomes this issue to successfully extract all generated charges prior to recombination in a BHJ. In this technique, a high voltage pulse accelerates electrode charging by nearly an order of magnitude, thus extracting charges more swiftly than they can recombine. This enables accurate quantification of charge generation efficiency in systems that exhibit even the most diffusive transport as well as studying charge recombination at early times. We demonstrate this capability on PCDTBT:PCBM OSC devices where recombination occurs even at 100s of ns. Using Overpulse TDCF enables the field-independent charge generation properties to be revealed in this system and accurate field dependence of CT-state separation in other systems. On the other hand, solvent processing conditions of BHJ active layers have shown to govern the final OSC nanostructure. In order to manipulate the morphology for a better understanding of its effect on charge generation, we have changed the processing solvent during the fabrication of the investigated systems in this work by using two different solvents, which plays an important role in defining the overall morphology. Where we used halogenated and non-halogenated solvents to track the effect of the morphology on the charge generation and recombination, the non-halogenated solvent gave us a new record with a power conversion efficiency of 7.7%. We correlate the device physics using OP-TDCF with nanomorphology via x-ray techniques, expanding our understanding of how the two aspects are interconnected. Moving forward, this technique will enable understanding the detailed processes of charge generation and recombination to work toward further progress in materials design and device fabrication.
BrainLeaks: On the Privacy-Preserving Properties of Neuromorphic Architectures against Model Inversion Attacks

description: With the mainstream integration of machine learning into security-sensitive domains such as healthcare and finance, concerns about data privacy have intensified. Conventional artificial neural networks (ANNs) have been found vulnerable to several attacks that can leak sensitive data. Particularly, model inversion (MI) attacks enable the reconstruction of data samples that have been used to train the model. Neuromorphic architectures have emerged as a paradigm shift in neural computing, enabling asynchronous and energy-efficient computation. However, little to no existing work has investigated the privacy of neuromorphic architectures against model inversion. Our study is motivated by the intuition that the non-differentiable aspect of spiking neural networks (SNNs) might result in inherent privacy-preserving properties, especially against gradient-based attacks. To investigate this hypothesis, we propose a thorough exploration of SNNs' privacy-preserving capabilities. Specifically, we develop novel inversion attack strategies that are comprehensively designed to target SNNs, offering a comparative analysis with their conventional ANN counterparts. Our experiments, conducted on diverse event-based and static datasets, demonstrate the effectiveness of the proposed attack strategies and therefore questions the assumption of inherent privacy-preserving in neuromorphic architectures.

description: Neural quantum state (NQS) ansätze have shown promise in variational Monte Carlo algorithms by their theoretical capability of representing any quantum state. However, the reason behind the practical improvement in their performance with an increase in the number of parameters is not fully understood. In this work, we systematically study the efficiency of a shallow neural network to represent the ground states in different phases of the spin-1 bilinear-biquadratic chain, as the number of parameters increases. We train our ansatz by a supervised learning procedure, minimizing the infidelity w.r.t. the exact ground state. We observe that the accuracy of our ansatz improves with the network width in most cases, and eventually saturates. We demonstrate that this can be explained by looking at the spectrum of the quantum geometric tensor (QGT), particularly its rank. By introducing an appropriate indicator, we establish that the QGT rank provides a useful diagnostic for the practical representation power of an NQS ansatz.

description: Dark photons, as a minimal extension of the Standard Model through an additional Abelian gauge group, may propagate relativistically across the galaxy, originating from dark matter decay or annihilation, thereby contributing to a galactic dark photon background. The generation of dark photons typically favors certain polarization modes, which are dependent on the interactions between dark matter and dark photons. We introduce a framework in which a resonant cavity is utilized to detect and differentiate these polarizations, leveraging the daily variation in expected signals due to the anisotropic distribution of dark photons and the rotation of the Earth. We conduct an experimental search using superconducting radio-frequency cavities, noted for their exceptionally high quality factors, proving them to be effective telescopes for observing galactic dark photons. This approach establishes the most stringent limits yet on the kinetic mixing coefficient between dark photons and electromagnetic photons, thereby unveiling a novel avenue for the indirect search for dark matter via multi-messenger astronomy.

MECHANICAL AND LONG-TERM CHARACTERIZATION OF SHOTCRETE-CONCRETE INTERFACE BONDS

description: Shotcrete is gaining popularity with vertical and overhead construction where conventional formworks and repairs are difficult to make, costly, and often short-lived. However, if the interface bond qualities between shotcrete and concrete are not adequately formed when the substrate concrete surface lacks cleanliness and soundness, this method could also potentially reduce the life expectancy of structures. In addition, long-term freeze-thaw weathering in northern states also weakens the shotcrete-concrete interface bonds, leading to debonding and rebar corrosion. Therefore, it is essential to characterize the shotcrete-concrete interface bonds to evaluate the performance of composite concrete structures. To this end, the shotcrete-concrete interface bond is evaluated under shear and tension for four substrate surface preparation techniques: chipped (C), pressure-washed (PW), sandblasted (SB), and as-cast (AC). A new mode-II fracture-based test is designed and developed to examine the resistance to potential crack initiation and propagation. Results are correlated with the topography of the substrate surface. A parametric study is conducted using combined concrete damage plasticity and a cohesive zone model on ABAQUS to identify failure mechanisms at the bond interface. The long-term freeze-thaw durability of shotcrete-concrete bonds is assessed, and a probabilistic damage model based on a Weibull distribution is introduced to predict the service life of such interfaces.
description: It is advised to use various test techniques to assess shotcrete-concrete interface bonds, as different surface preparation methods perform better under certain loading conditions. Nevertheless, the highest surface bond strength and mode-II fracture energy were reported by C. The proposed mode-II fracture-based test offers a viable alternative for bond characterization leading to results with similar variations as shear bond tests. In direct tension tests, profiles with estimated surface texture depths greater than 0.294 mm demonstrated strong bonding. C demonstrated the highest resistance to frost damage, followed by PW and SB, which exhibited comparable degradation. After 300 freeze-thaw cycles, the tensile strength of AC decreased by more than 90%, emphasizing the significance of surface preparation in shotcrete construction. The experimental tests and the finite element analysis showed a strong correlation and verified the existence of adhesive, cohesive, and combined adhesive-cohesive failure modes.

description: Locomotion gaits are fundamental for control of soft terrestrial robots. However, synthesis of these gaits is challenging due to modeling of robot-environment interaction and lack of a mathematical framework. This work presents an environment-centric, data-driven and fault-tolerant probabilistic Model-Free Control (pMFC) framework that allows for soft multi-limb robots to learn from their environment and synthesize diverse sets of locomotion gaits for realizing open-loop control. Here, discretization of factors dominating robot-environment interactions enables an environment-specific graphical representation where the edges encode experimental locomotion data corresponding to the robot motion primitives. In this graph, locomotion gaits are defined as simple cycles that are transformation invariant, i.e., the locomotion is independent of the starting vertex of these periodic cycles. Gait synthesis, the problem of finding optimal locomotion gaits for a given substrate, is formulated as Binary Integer Linear Programming (BILP) problems with a linearized cost function, linear constraints, and iterative simple cycle detection. Experimentally, gaits are synthesized for varying robot-environment interactions. Variables include robot morphology - three-limb and four-limb robots, TerreSoRo-III and TerreSoRo-IV; substrate - rubber mat, whiteboard and carpet; and actuator functionality - simulated loss of robot limb actuation. On an average, gait synthesis improves the translation and rotation speeds by 82% and 97% respectively. The results highlight that data-driven methods are vital to soft robot locomotion control due to the significant influence of unexpected asymmetries in the system and the dependence of optimal gait sequences on the experimental robot-environment interaction.

Anaplasma marginale infection dynamics in an edemic area
Creators: name: Koku, Roberta
Publisher: name: Washington State University
Year: 2023

description: Anaplasma marginale, the cause of bovine anaplasmosis, is a tick-transmitted disease responsible for economic losses to the cattle industry worldwide. The disease is characterized by progressive anemia, reduced production and death. In areas of high transmission, most animals are infected with multiple strains, which through time may lead to more severe outcomes. Multistrain infections may occur either by co-infection when multiple strains infect a host prior to an adaptive immune response or by superinfection, when a second strain establishes infection following an immune response to the initial strain. We address this knowledge gap by tracking the acquisition of A. marginale strains overtime under natural transmission conditions in a cattle herd in southern Ghana. We first determined that 97% of animals in the study herd have multistrain infections and these strains are acquired by co-infection and superinfection. On average, the number of strains acquired via superinfection was 16% lower than the number of strains acquired by co-infection. In A. marginale sequential variation in major surface protein 2 (Msp2), and outer membrane protein allows for immune evasion and superinfection. Msp2 is encoded by up to 10 alleles that are recombined into a single expression site. In experimental infections, strains that differ in at least one genetically distinct msp2 allele can establish superinfection which is accompanying by relative over-expression of the unique allele. The contribution of msp2 allelic variation to superinfection in a natural transmission setting is unknown. In our study herd in southern Ghana, we tracked the msp2 allelic repertoire and its usage at coinfection and superinfection. We identified new msp2 pseudogenes in all animals at superinfection. Of all expressed Msp2 variants at superinfection, an average of 32% were derived from the new pseudogenes in three animals, while none of the new pseudogenes were expressed in two of the animals. Thus, superinfection is associated with the introduction of new pseudogenes, but these new pseudogenes are not over-expressed at superinfection. Overall, these studies are the first major steps in unravelling the complexity of how multistrain infections are established in a natural transmission setting and though time will help in developing more sophisticated intervention strategies.

description: This work constitutes the second part of a series of studies that aim to utilise tools from Hamiltonian mechanics to investigate the motion of an extended body in general relativity. The first part of this work [Refs. [1, 2]] constructed a ten-dimensional, covariant Hamiltonian framework encompassing all the linear-in-spin corrections to the geodesic motion in arbitrary spacetime. This framework was proven to be integrable in the Schwarzschild and Kerr spacetimes, specifically. The present work translates this abstract integrability result into tangible applications for linear-in-spin Hamiltonian dynamics of a compact object in a Schwarzschild spacetime. In particular, a canonical system of coordinates is constructed explicitly, which exploits the spherical symmetry of the Schwarzschild spacetime. These coordinates are based on a relativistic generalization of the classical Andoyer variables of Newtonian rigid body motion. This canonical setup allows us to derive ready-to-use formulae for action-angle coordinates and gauge-invariant Hamiltonian frequencies, which automatically include all linear-in-spin effects. No external parameters or ad hoc choices are necessary, and the framework can be used to find complete solutions by quadrature of generic (bound or unbound), linear-in-spin orbits, including orbital inclination, precession and eccentricity, as well as spin precession. The efficacy of the formalism is demonstrated here in the context of circular orbits with arbitrary spin and orbital precession, with the results validated against known results in the literature.

description: In this article, we examine the gravitational deflection of particles in curved spacetime immersed in perfect fluid in the context of Rastall theory. We propose an infinite region approach to Gibbons-Werner to avoid singularity, given that the integral region is generally infinite. In the Rastall theory framework, the black hole solutions in the dust field are studied. Additionally, we check the deflection angle from this spacetime under the influence of plasma. Furthermore, we analytically compute plasma's impact on a black hole shadow using a ray-tracing approach and Hamiltonian equation. Hence, the light ray motion equations are independent of the plasma's velocity. It is assumed that plasma is a dispersive medium, pressureless and non-magnetised, and the plasma particle density corresponds to particle accumulation. The supermassive black hole's shadow and emitted energy are explored when plasma falls radially from infinity onto the black hole.

THE ROLES OF AHLS IN LIGHT-MEDIATED GROWTH IN ARABIDOPSIS
Creators: name: Jacques, Caitlin
Publisher: name: Washington State University
Year: 2023

description: Transcriptional regulation of developmental processes is particularly important for plants, which are sessile organisms. The pathways that are involved in these processes can be studied using growth media plates. The use of growth media plates has several advantages over soil-grown plants, such as reproducibility, ease of use, and affordability. When the production location of Phytagel (Sigma) moved, the subtle phenotypes of key mutants involved in light-mediated growth were not reproducible. Since the original formula was discontinued, a new gelling agent, Gellan, was tested and found to be a suitable replacement. One of the non-reproducible phenotypes affected by the new Phytagel formula is conferred by null allele combinations in the AT-HOOK MOTIF CONTAINING NUCLEAR LOCALIZED (AHL) family. The AHLs are a family of transcription factors involved in regulating growth and development in the model plant Arabidopsis thaliana (Arabidopsis). One member of the AHL family, AHL29/SUPRESSOR OF PHYB4 #3 (SOB3), has been shown to regulate light-mediated growth and development of the hypocotyl in Arabidopsis. Until now, the majority of studies on SOB3 have been in continuous light or long day growing conditions. Therefore, Arabidopsis was used to study how SOB3 regulates hypocotyl elongation throughout short days (SD). SOB3 inhibits hypocotyl growth in SD, which is consistent with its effects in constant light. The RNA-seq data indicates that PHYTOCHROME INTERACTING FACTORS (PIFs) 4, 5, 7, and 8 along with PIF-target genes are repressed by AHLs. Several of the repressed PIF target genes identified have not been previously described as AHL-regulated, including PRE1, PIL1, HFR1, CDF5, and XTR7. Genes involved in hormone signaling have also been found to be AHL-repressed, such as members of gibberellic acid-stimulating Arabidopsis (GASA) family, GAS4 and GASA14. The RNA-seq data also suggests that AHLs activate the expression of growth repressors to control hypocotyl elongation, such as HY5 and IAA17. While different genes were regulated by SOB3 at different time points in SD, ChIP-seq data suggests that SOB3 binds to similar genes throughout the day. This indicates that SOB3 is likely interacting with other AHLs or other proteins to control the expression of these target genes.

description: Aims. We explore different scenarios to explain the chemical difference found in the remarkable giant-giant binary system HD 138202 + CD-30 12303. For the first time, we suggest how to distinguish these scenarios by taking advantage of the extensive convective envelopes of giant stars. Methods. We carried out a high-precision determination of stellar parameters and abundances by applying a full line-by-line differential analysis on GHOST high-resolution spectra. Results. We found a significant chemical difference between the two stars (0.08 dex), which is largely unexpected considering the insensitivity of giant stars to planetary ingestion and diffusion effects. We tested the possibility of engulfment events by using several different combinations of stellar mass, ingested mass, metallicity of the engulfed object and different convective envelopes. However, the planetary ingestion scenario does not seem to explain the observed differences. For the first time, we distinguished the source of chemical differences using a giant-giant binary system. By ruling out other possible scenarios such as planet formation and evolutionary effects between the two stars, we suggest that primordial inhomogeneities might explain the observed differences. This remarkable result implies that the metallicity differences that were observed in at least some main-sequence binary systems might be related to primordial inhomogeneities rather than engulfment events. We also discuss the important implications of finding primordial inhomogeneities, which affect chemical tagging and other fields such as planet formation. We strongly encourage the use of giant-giant pairs. They are a relevant complement to main-sequence pairs for determining the origin of the observed chemical differences in multiple systems.

description: Improving a 2003 result of Bohman and Holzman, we show that for $n \geq 1$, the Shannon capacity of the complement of the $2n+1$-cycle is at least $(2^{r_n} + 1)^{1/r_n} = 2 + Ω(2^{-r_n}/r_n)$, where $r_n = \exp(O((\log n)^2))$ is the number of partitions of $2(n-1)$ into powers of $2$. We also discuss a connection between this result and work by Day and Johnson in the context of graph Ramsey numbers.

description: For phase data from frequency-tagged EEG data Bayesian modelling gives results that are clean, it is very data efficient when effects are real and less likely to fool you with noise that looks like an effect but isn't! It allows you to arrange the model around the experiment and describes the data in terms of a clear model and posterior probabilities instead of the often confusing picture presented by hypothesis testing and frequentist statistics.
