description: The availability of protein is an important factor for the determination of the size of the mitotic spindle. Involved in spindle-size regulation is kinesin-8, a molecular motor and microtubule (MT) depolymerase, which is known to tightly control MT length. Here, we propose and analyze a theoretical model in which kinesin-induced MT depolymerization competes with spontaneous polymerization while supplies of both tubulin and kinesin are limited. In contrast to previous studies where resources were unconstrained, we find that, for a wide range of concentrations, MT length regulation is bistable. We test our predictions by conducting in vitro experiments, and find that the bistable behavior manifests in a bimodal MT length distribution.

description: We introduce and raise awareness of NASA’s GMAT (General Mission-design and Analysis Tool) software system tool for spacecraft trajectory optimization and mission design, navigation and orbit analysis. GMAT is developed by NASA Goddard Space Flight Center (GSFC) in collaboration with private industry, public developers and various national space agencies. The tool has applications in all orbital regimes (mission to libration points, LEOs, landing scenarios, gravity-assist fly-by’s). GMAT is fully tested and certified for operational use and was chosen as the primary operational tool for NASA’s ACE (Advanced Composition Explorer) mission for maneuver planning, orbit determination. Various spacecraft models (various thruster models, impulse burn, etc), numerical propagators (Prince-Dormand, Adams-Bashford) and force models (atmospheric drag, solar pressure, etc.) are implemented. GMAT was selected as the primary mission design tool for NASA’s TESS space telescope mission and was used for mission design for the James Webb Space Telescope. At SDU/SDU-Galaxy we have embarked on weekly workshop-like meetings to gradually gain experience with this tool aiming to apply gained knowledge to the Århus University-led “STEP-A” space telescope mission (2025/2026) and optimal geolocation-planning of ground stations (based on predicted TLE’s) for effective Earth-spacecraft communication and data telemetry. This tool can also be used for science communication, STEM outreach activities raising awareness of space science, spacecraft control and astrodynamics.

As an application we study the standard electroweak potential, showing that for a Higgs mass above 70 GeV, and afirly independent of the top mass (with $m_{t} > 90 GeV$, the 1-loop approximation is no longer valid for temperatures in the neighborhood of the critical temperature.

description: We compute the time-dependent coverage in the random sequential adsorption of aligned d-dimensional cubes in $R^d$ using time-series expansions. The seventh-order series in 2, 3 and 4 dimensions is resummed in order to predict the coverage at jamming. The result is in agreement with Monte-Carlo simulations. A simple argument, based on a property of the perturbative expansion valid at arbitrary orders, allows us to analytically derive some generalizations of the Palásti approximation.

$H_0$ from cosmic chronometers and Type Ia supernovae, with Gaussian Processes and the novel Weighted Polynomial Regression method

description: In this paper we present new constraints on the Hubble parameter $H_0$ using: (i) the available data on $H(z)$ obtained from cosmic chronometers (CCH); (ii) the Hubble rate data points extracted from the supernovae of Type Ia (SnIa) of the Pantheon compilation and the Hubble Space Telescope (HST) CANDELS and CLASH Multy-Cycle Treasury (MCT) programs; and (iii) the local HST measurement of $H_0$ provided by Riess et al. (2018), $H_0^{\rm HST}=(73.45\pm1.66)$ km/s/Mpc. Various determinations of $H_0$ using the Gaussian processes (GPs) method and the most updated list of CCH data have been recently provided by Yu, Ratra and Wang (2018). Using the Gaussian kernel they find $H_0=(67.42\pm 4.75)$ km/s/Mpc. Here we extend their analysis to also include the most released and complete set of SnIa data, which allows us to reduce the uncertainty by a factor $\sim 3$ with respect to the result found by only considering the CCH information. We obtain $H_0=(67.06\pm 1.68)$ km/s/Mpc, which favors again the lower range of values for $H_0$ and is in tension with $H_0^{\rm HST}$. The tension reaches the $2.71σ$ level. We round off the GPs determination too by taking also into account the error propagation of the kernel hyperparameters when the CCH with and without $H_0^{\rm HST}$ are used in the analysis. In addition, we present a novel method to reconstruct functions from data, which consists in a weighted sum of polynomial regressions (WPR). We apply it from a cosmographic perspective to reconstruct $H(z)$ and estimate $H_0$ from CCH and SnIa measurements. The result obtained with this method, $H_0=(68.90\pm 1.96)$ km/s/Mpc, is fully compatible with the GPs ones. Finally, a more conservative GPs+WPR value is also provided, $H_0=(68.45\pm 2.00)$ km/s/Mpc, which is still almost $2σ$ away from $H_0^{\rm HST}$.

description: Rapidly rotating, chemically homogeneously evolving massive stars are considered to be progenitors of long gamma-ray bursts. We present numerical simulations of the evolution of the circumstellar medium around a rapidly rotating 20 Msol star at a metallicity of Z=0.001. Its rotation is fast enough to produce quasi-chemically homogeneous evolution. While conventionally, a star of 20 Msol would not evolve into a Wolf-Rayet stage, the considered model evolves from the main sequence directly to the helium main sequence. We use the time-dependent wind parameters, such as mass loss rate, wind velocity and rotation-induced wind anisotropy from the evolution model as input for a 2D hydrodynamical simulation. While the outer edge of the pressure-driven circumstellar bubble is spherical, the circumstellar medium close to the star shows strong non-spherical features during and after the periods of near-critical rotation. We conclude that the circumstellar medium around rapidly rotating massive stars differs considerably from the surrounding material of non-rotating stars of similar mass. Multiple blue-shifted high velocity absorption components in gamma-ray burst afterglow spectra are predicted. As a consequence of near critical rotation and short stellar evolution time scales during the last few thousand years of the star's life, we find a strong deviation of the circumstellar density profile in the polar direction from the 1/R^2 density profile normally associated with stellar winds close to the star

description: The staggered magnetization of the Heisenberg antiferromagnet in two dimensions can be systematically approximated by a 1/N expansion. Cancellation between self energy diagrams leads to a Luttinger-like theorem for the ground state. We prove (for a smooth enough self energy) that the long range order of mean field theory ($N$=$\infty$) survives corrections to all orders of 1/N. Divergences of this series provides a new route to the disordered phases of quantum antiferromagnets.

description: We previously showed that Caco-2 cell absorption of β-carotene from taurocholic acid (TA)-based mixed micelles differed depending on the composition of the micelles. In this study, the shapes and sizes of TA-based mixed micelles, that is, mixed micelles of TA, 1-oleoyl-rac-glycerol (MG), oleic acid (OLA), and either 1-palmitoyl-sn-glycero-3-phosphocholine (MPPC; i.e., a lysophospholipid) or 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC; i.e., a phospholipid) (60:3:1:0.75–12) were determined by using small-angle X-ray scattering (SAXS). We found that increasing the ratio of MPPC in mixed micelles of TA, MG, OLA, and MPPC was responsible for the previously observed enhanced β-carotene absorption by Caco-2 cells and changed the micelle shape from core–shell spherical to core–shell ellipsoidal. In contrast, increasing the ratio of POPC in mixed micelles of TA, MG, OLA, and POPC was responsible for the suppressed β-carotene absorption by the cells, changed the micelle shape from core–shell spherical to core–shell ellipsoidal to core–shell cylindrical, and caused a rapid increase in micelle volume. These results will be useful for understanding the mechanisms that mediate β-carotene absorption by cells and for developing technologies to improve the intestinal absorption of lipophilic components of drugs and nutrients.

In shift-symmetric theories invariant under the shift of scalar $ϕ\to ϕ+c$, we show the existence of new hairy BH solutions where a cubic-order scalar-vector interaction gives rise to a scalar hair manifesting itself around the event horizon. In the presence of a quartic-order interaction besides the cubic coupling, there are also regular BH solutions endowed with scalar and vector hairs.

Abstract  
Mirvetuximab soravtansine (ElahereTM), an antibody-drug conjugate carrying a maytansinoid payload targeting folate receptor alpha (FRα), is a valuable new treatment option for patients with FRα-positive, platinum-resistant ovarian cancer. Mirvetuximab soravtansine significantly improved objective response rates compared with historical rates in patients with FRα-positive, platinum-resistant ovarian cancer in the phase 2 SORAYA trial. In the confirmatory phase 3 MIRASOL trial, mirvetuximab soravtansine significantly improved median progression-free survival, objective response rates, and median overall survival compared with investigator’s choice of nonplatinum chemotherapy in patients with this indication. Mirvetuximab soravtansine has manageable tolerability, with eye disorders being the most common treatment-related adverse event.

description: Technology applications including games are generally not designed with the blind or visually impaired in mind. This is an invaluable area of research as it is this population that would benefit the most from accessible technology enabling inclusion and participation in society. “Nobody makes games for us” was a motivator for this research. This paper describes the process of creating a set of audio games for the visually impaired. The principles of audio game design are discussed and based upon these the Audio Game Hub is proposed. Audio Game Hub is currently a set of four audio games that have suitable interfaces for the visually impaired. Audio Game Hub is currently available for download on multiple platforms and has seen popularity with both visually impaired and normal sighted players, which provides an area for future research.

For 138 Galactic globulars we obtain $=-7.41\pm0.11$, $σ(M_V)=1.24$ mag, $h_3=0.02\pm 0.05$, and $h_4=0.06 \pm 0.05$, {\em i.e.\/} the core of the distribution does not differ significantly from a Gaussian. For a low-metallicity subsample of 103 globular clusters with $[Fe/H]=-7.48\pm0.11$, $σ(M_V)=1.08$ mag, $h_3=0.05 \pm 0.05$, and $h_4=0.13 \pm 0.05$.

description: We have found a sample of extreme emission-line galaxies (EELGs) with strong [OIII]$λ$5007 emission at z $\sim$ 0.5. Using broadband photometric selection and requiring small uncertainties in photometry, we searched the 14th Data Release (DR14) of the Sloan Digital Sky Survey (SDSS) and found 2658 candidates with strong i-band excess (i - z $\leqslant$ r - i - 0.7). We further obtained 649 SDSS spectra of these objects, and visually identified 22 [OIII] emitters lying at 0.40 $$ 3 is 12 + log(O/H) = 7.98$^{+0.12}_{-0.02}$, with a median value of 8.24$^{+0.05}_{-0.04}$. Our [OIII] emitters exhibit remarkably high line luminosity - 18/22 have L$_{\rm [OIII]\lambda5007}$ $>$ 5$\times$10$^{42}$ erg $\rm s^{-1}$ and 5/22 have L$_{\rm [OIII]\lambda5007}$ $>$ 10$^{43}$ erg $\rm s^{-1}$. Their estimated volume number density at z $\sim$ 0.5 is $\sim$ 2$\times$10$^{-8}$ Mpc$^{-3}$, with L$_{\rm [OIII]\lambda5007}$ down to $\sim$ 3$\times$10$^{42}$ erg $\rm s^{-1}$. The cumulative number fraction distribution of EELGs across different redshifts is indicative of a strong redshift evolution at the bright end of the [OIII] luminosity function.

description: We show that a large anomalous contribution due to nonperturbative instanton-like gluonic field configurations to the axial charge of the proton implies high-energy spin effects in $p-p$ elastic scattering. This is the same mechanism which is responsible for anomalous baryon number violation at high energy in the standard model. We compute the proton polarization due to these effects and we show that it is proportional to the center-of-mass scattering angle with a universal (energy-independent) slope of order unity.

description: Durante os onze anos de luta de lilbertação na Guiné-Bissau, diversos cineastas ocidentais documentaram como o Partido Africano para a Independência da Guiné e Cabo-Verde (PAIGC) desenvolvia uma acção militar contra o exército colonial português e simultaneamente criava, nas zonas libertadas, hospitais, escolas, tribunais populares e armazéns do povo. Na organização social e política das zonas libertadas seriam atribuídas às mulheres novas funções e responsabilidades, capazes de ativar mecanismos para a sua emancipação e para uma transformação nos papéis de género. Neste artigo, proponho discutir as representações históricas e políticas das mulheres nestes filmes, justapondo-as com um trabalho etnográfico realizado na tabanca de Unal, um dos primeiros bastiões das zonas libertadas. Esta justaposição permitirá discutir uma pluralidade de perspetivas que questionam a uniformidade do projeto político que o PAIGC propunha implementar. Permitirá ainda revelar inesperadas conjeturas de ascensão social e de resistência, desencadeadas pelas mulheres que viviam nas zonas libertadas, as quais carecem de reflexão e problematização histórica.

description: Contamination of surface soils with lead (Pb) is a global concern due to the release of hazardous materials containing the metal element. In order to explore ways to remediate contaminated soils with less impact on environment and costs, this study aimed at screening ornamental plant species exposed to Pb gradient in spiked soils for Pb phytoextraction. Twenty-one ornamental plant species that currently grow in Pakistan, were selected to assess their potential for Pb accumulation. Pot experiments were conducted to evaluate the accumulative properties of the different plant species in unspiked control (Pb = 0) and spiked soils with different levels of Pb at 500, 1000, 1500 and 2000 mg Pb kg−1 of soil. Biotranslocation factor (TF), Enrichment factor (EF) and Bioconcentration factor (CF) were calculated to assess the phytoremediation potential of tested plant species after seven weeks of exposure. Out of 21 plant species, Pelargonium hortorum and Mesembryanthemum criniflorum performed better and accumulated more than 1000 mg Pb kg−1 of shoot dry biomass when they were grown in 500, 1000 and 1500 mg Pb kg−1 contaminated soils. Both plants had no significant (P < 0.05) variation in the total dry biomass with increasing soil Pb concentration indicating a high tolerance to Pb. Considering the capacity of Pb accumulation, total dry biomass, TF, EF & CF indices, Pelargonium hortorum and Mesembryanthemum criniflorum could be considered as Pb hyperaccumulators and could have the potential to be used in phytoremediation.

description: At present, MAJORANA is a research and development (R&D) project to investigate the feasibility and cost of constructing and operating a one ton decay experiment with ~1000 kg of Ge detectors fabricated from germanium enriched to 86% in . The study will include three separate cryostats with various types of detectors: un-segmented, un-segmented point-contact, minimally segmented, and highly segmented. One cryostat will contain at least 30 kg of enriched (preferably point-contact) detectors. The performance of the cryostats and detectors as well as background levels will be investigated. The goal of the demonstrator project is to reach a discovery sensitivity of ~ 1026 y.

description: This article introduces the genre of a digital audio game and discusses selected play interaction solu-tions implemented in the Audio Game Hub, a prototype designed and evaluated in the years 2014 and 2015 at the Gamification Lab at Leuphana University Lüneburg.1 The Audio Game Hub constitutes a set of familiar playful activities (aiming at a target, reflex-based reacting to sound signals, labyrinth exploration) and casual games (e.g. Tetris, Memory) adapted to the digital medium and converted into the audio sphere, where the player is guided predominantly or solely by sound. The authors will discuss the design questions raised at early stages of the project, and confront them with the results of user experience testing performed on two groups of sighted and one group of visually impaired gamers.

description: We calculate two-body $J^π=0^{+}, 1^{+}$, and $J^π=2^{+}$ resonance states of $Y_{c}$ ($= Λ_{c}$, $Σ_{c}$, or $Σ_{c}^{*}$) and $N$ using the complex scaling method. We employ the $Y_{c}N$-CTNN potentials, which were proposed in our previous study, and obtain four resonances near $Σ_{c}N$ and $Σ_{c}^{*}N$ thresholds. From the analysis by the binding energies of partial channel systems, we conclude that these resonance states are Feshbach resonances. We compare the results with the $Y_{c}N$ resonance states in the heavy quark limit, where the $Σ_{c}N$ and $Σ_{c}^{*}N$ thresholds are degenerate, and find that they form two pairs of the heavy-quark doublets in agreement with the heavy quark spin symmetry.

description: Higgs pair production is a crucial phenomenological process in deciphering the nature of the TeV scale and the mechanism underlying electroweak symmetry breaking. At the Large Hadron Collider, this process is statistically limited. Pushing the energy frontier beyond the LHC's reach will create new opportunities to exploit the rich phenomenology at higher centre-of-mass energies and luminosities. In this work, we perform a comparative analysis of the $hh+\text{jet}$ channel at a future 100 TeV hadron collider. We focus on the $hh\to b\bar b b\bar b$ and $hh \to b\bar b τ^+τ^-$ channels and employ a range of analysis techniques to estimate the sensitivity potential that can be gained by including this jet-associated Higgs pair production to the list of sensitive collider processes in such an environment. In particular, we observe that $hh \to b\bar b τ^+τ^-$ in the boosted regime exhibits a large sensitivity to the Higgs boson self-coupling and the Higgs self-coupling could be constrained at the 8\% level in this channel alone.

description: We present results on the non-linear dynamics of inhomogeneous cosmological models with irrotational dust and a positive cosmological constant, considering, in particular, a wide class with vanishing magnetic Weyl tensor. For those patches of the universe that do not recollapse to a singularity we find a unique attractor, representing a de Sitter vacuum phase. For the (re-)collapsing regions we find a family of (Kasner) attractors, so that generically these regions fall in spindle-like singularities. These results give substantial support to the idea that the universe can be very inhomogeneous on ultra-large, super-horizon scales, whit observers living in those (almost) isotropic regions that emerge from an inflationary phase.

description: We propose a scheme to make use of recent advances in cavity QED-enhanced resonance fluorescence from quantum dots to generate a stream of entangled and indistinguishable photons. We then demonstrate that we can optically manipulate the state of a trapped hole spin to achieve complete coherent control of a qubit. In combination with the selective cavity enhancement of the resonantly excited transition, we use this capability to perform a proof-of-principle demonstration of our proposal by showing that the time bin of a single photon is dependent on the measured state of the trapped spin.

description: We reconsider the recent derivation by de Rafael and Taron of bounds on the slope of the Isgur-Wise function. We argue that one must be careful to include cuts starting below the heavy meson pair production threshold, arising from heavy quark-antiquark bound states, and that if such cuts are properly accounted for then no constraints may be derived.

description: A new class of exoplanets is beginning to emerge: planets whose dayside atmospheres more closely resemble stellar atmospheres as most of their molecular constituents dissociate. The effects of the dissociation of these species will be varied and must be carefully accounted for. Here we take the first steps towards understanding the consequences of dissociation and recombination of molecular hydrogen (H$_2$) on atmospheric heat recirculation. Using a simple energy balance model with eastward winds, we demonstrate that H$_2$ dissociation/recombination can significantly increase the day$-$night heat transport on ultra-hot Jupiters (UHJs): gas giant exoplanets where significant H$_2$ dissociation occurs. The atomic hydrogen from the highly irradiated daysides of UHJs will transport some of the energy deposited on the dayside towards the nightside of the planet where the H atoms recombine into H$_2$; this mechanism bears similarities to latent heat. Given a fixed wind speed, this will act to increase the heat recirculation efficiency; alternatively, a measured heat recirculation efficiency will require slower wind speeds after accounting for H$_2$ dissociation/recombination.

description: The 2004-2012 X-ray time history of the NS LMXB GRS 1724-308 shows, along with the episodic brightenings associated to the low-high state transitions typical of the ATOLL sources, a peculiar, long lasting (about 300 d) flaring event, observed in 2008. This rare episode, characterised by a high-flux hard state, has never been observed before for GRS 1724-308 , and in any case is not common among ATOLL sources. We discuss here different hypotheses on the origin of this peculiar event that displayed the spectral signatures of a failed transition, similar in shape and duration to those rarely observed in Black Hole binaries. We also suggest the possibility that the atypical flare occurred in coincidence with a new rising phase of the 12-years super-orbital modulation that has been previously reported by other authors. The analysed data also confirm for GRS 1724-308 the already reported orbital period of about 90 d.

description: This paper presents experimental results about transport of dilute suspensions of nano-objects in silicon-glass micrometric and sub-micrometric channels. Two kinds of objects are used: solid, rigid latex beads and spherical capsule-shaped, soft polymersomes. They are tracked using fluorescence microscopy. Three parameters are studied: confinement (ratio between particle diameter and channel depth), Brownian diffusion and particle nature. The aim of this work is to understand how these different parameters affect the transport of suspensions in narrow channels and to understand the different mechanisms at play. Concerning the solid beads we observe the appearance of two regimes, one where the experimental mean velocity is close to the expected one and another where this velocity is lower. This is directly related to a competition between confinement, Brownian diffusion and advection. These two regimes are shown to be linked to the homogeneity of particles distribution in the channel depth, which we experimentally deduce from velocity distributions. This inhomogeneity appears during the entrance process into the sub-micrometric channels, as for hydrodynamic separation or deterministic lateral displacement. Concerning the nature of the particles we observed a shift of transition towards the second regime likely due to the relationships between shear stress and polymersomes mechanical properties which could reduce the inhomogeneity imposed by the geometry of our device.

description: State of the art quantum transport models for semiconductor nanodevices attribute negative (positive) unit charges to states of the conduction (valence) band. Hybrid states that enable band-to-band tunneling are subject to interpolation that yield model dependent charge contributions. In any nanodevice structure, these models rely on device and physics specific input for the dielectric constants. This paper exemplifies the large variability of different charge interpretation models when applied to ultrathin body transistor performance predictions. To solve this modeling challenge, an electron-only band structure model is extended to atomistic quantum transport. Performance predictions of MOSFETs and tunneling FETs confirm the generality of the new model and its independence of additional screening models.

description: In this work we construct a bottom-up reconstruction technique for Loop Quantum Cosmology scalar-tensor theories, from the observational indices. Particularly, the reconstruction technique is based on fixing the functional form of the scalar-to-tensor ratio as a function of the $e$-foldings number. The aim of the technique is to realize viable inflationary scenarios, and the only assumption that must hold true in order for the reconstruction technique to work is that the dynamical evolution of the scalar field obeys the slow-roll conditions. We shall use two functional forms for the scalar-to-tensor ratio, one of which corresponds to a popular inflationary class of models, the $α$-attractors. For the latter, we shall calculate the leading order behavior of the spectral index and we shall demonstrate that the resulting inflationary theory is viable and compatible with the latest Planck and BICEP2/Keck-Array data. In addition, we shall find the classical limit of the theory, and as we demonstrate, the Loop Quantum Cosmology corrected theory and the classical theory are identical at leading order in the perturbative expansion quantified by the parameter $ρ_c$, which is the critical density of the quantum theory. Finally, by using the formalism of slow-roll scalar-tensor Loop Quantum Cosmology, we shall investigate how several inflationary potentials can be realized by the quantum theory, and we shall calculate directly the slow-roll indices and the corresponding observational indices. In addition, the $f(R)$ gravity frame picture is presented.

Publisher: name: Zenodo
Year: 2007

description: This presentation was part of a 2-day workshop provided for the Australian Bureau of Meteorology during 15-16 October 2007. The workshop targets system administrators whose task is to setup a data service for interactive users, batch processes, and high level web services, that will access netcdf, hdf, or freeform data in a file system or SQL data in a database. The workshop provides them with the information they need to install and configure Hyrax along with some background on available clients so they can test their servers and give basic advice to users.

Summary of the slide deck: The Hyrax Architecture consists of two main components: the Front-end (OLFS) and the Back-end (BES). The Front-end provides a DAP interface and handles Authentication & Authorization, while the Back-end reads data from various sources. Both components are customizable, allowing for different network protocols and data formats/systems. The architecture supports single or multiple machine installations and emphasizes security considerations, with Authentication & Authorization handled by web servers like Tomcat and Apache. Extensions to both OLFS and BES can be added using Java or C/C++ modules, enhancing functionality and customization. Additionally, THREDDS catalogs are utilized to define logical data hierarchies and provide access to data through various protocols. Security features, such as Authentication & Authorization, are implemented using Tomcat's capabilities based on Realms and roles. Logging mechanisms are also discussed, including access logging using Tomcat's AccessLogValve class and informational/debug logging using Log4j for both OLFS and BES components.

description: Monogamy relations characterize the distributions of entanglement in multipartite systems. We investigate monogamy relations related to the concurrence C, the entanglement of formation E, negativity Nc and Tsallis-q entanglement Tq. Monogamy relations for the $α$th power of entanglement have been derived, which are tighter than the existing entanglement monogamy relations for some classes of quantum states. Detailed examples are presented.
