description: The recently detected TRAPPIST-1 planetary system, with its seven planets transiting a nearby ultracool dwarf star, offers the first opportunity to perform comparative exoplanetology of temperate Earth-sized worlds. To further advance our understanding of these planets' compositions, energy budgets, and dynamics, we are carrying out an intensive photometric monitoring campaign of their transits with the $\textit{Spitzer Space Telescope}$. In this context, we present 60 new transits of the TRAPPIST-1 planets observed with $\textit{Spitzer}$/IRAC in February and March 2017. We combine these observations with previously published $\textit{Spitzer}$ transit photometry and perform a global analysis of the resulting extensive dataset. This analysis refines the transit parameters and provides revised values for the planets' physical parameters, notably their radii, using updated properties for the star. As part of our study, we also measure precise transit timings that will be used in a companion paper to refine the planets' masses and compositions using the transit timing variations method. TRAPPIST-1 shows a very low level of low-frequency variability in the IRAC 4.5-$μ$m band, with a photometric RMS of only 0.11$\%$ at a 123-s cadence. We do not detect any evidence of a (quasi-)periodic signal related to stellar rotation. We also analyze the transit light curves individually, to search for possible variations in the transit parameters of each planet due to stellar variability, and find that the $\textit{Spitzer}$ transits of the planets are mostly immune to the effects of stellar variations. These results are encouraging for forthcoming transmission spectroscopy observations of the TRAPPIST-1 planets with the $\textit{James Webb Space Telescope}$.

description: We extend to the multi-asset case the framework of a discrete time model of a single asset financial market developed in Ghoulmie et al (2005). In particular, we focus on adaptive agents with threshold behavior allocating their resources among two assets. We explore numerically the effect of this diversification as an additional source of complexity in the financial market and we discuss its destabilizing role. We also point out the relevance of these studies for financial decision making.

description: The hysteretic ac loss of a current-carrying conductor in which multiple superconducting strips are polygonally arranged around a cylindrical former is theoretically investigated as a model of superconducting cables. Using the critical state model, we analytically derive the ac loss $Q_n$ of a total of $n$ strips. The normalized loss $Q_n/Q_1$ is determined by the number of strips $n$ and the ratio of the strip width $2w$ to the diameter $2R$ of the cylindrical former. When $n>> 1$ and $w/R<< 1$, the behavior of $Q_n$ is similar to that of an infinite array of coplanar strips.

description: The shallow water equations (SWE) are a widely used model for the propagation of surface waves on the oceans. We consider the problem of optimally determining the initial conditions for the one-dimensional SWE in an unbounded domain from a small set of observations of the sea surface height. In the linear case we prove a theorem that gives sufficient conditions for convergence to the true initial conditions. At least two observation points must be used and at least one pair of observation points must be spaced more closely than half the effective minimum wavelength of the energy spectrum of the initial conditions. This result also applies to the linear wave equation. Our analysis is confirmed by numerical experiments for both the linear and nonlinear SWE data assimilation problems. These results show that convergence rates improve with increasing numbers of observation points and that at least three observation points are required for the practically useful results. Better results are obtained for the nonlinear equations provided more than two observation points are used. This paper is a first step in understanding the conditions for observability of the SWE for small numbers of observation points in more physically realistic settings.

Publisher: name: University of Illinois at Chicago
Year: 2024

description: Liquid electrolytes based on the organic solvents are the promising candidates for lithium-ion batteries. One of the most successful salt electrolyte systems are lithium hexafluorophosphate (LiPF6) and Lithium bis(trifluoromethanesulfonic) imide (LiTFSI) in ethylene carbonate/ethyl methyl carbonate (EC/EMC) mixture. Here we discuss ab initio molecular dynamics and classical molecular dynamics simulations of 1M and 3.5M of LiPF6 and 1M and 3.5M of LiTFSI salts in EC/EMC (11:25 v/v) systems. Particular attention is paid to the local structure organization at the atomistic level using the radial distributions between the constituents of electrolyte, as well as to their mutual coordination ability. The obtained results were confirmed by the comparison of the theoretically estimated structure factor with experimental small-angle X-ray scattering measurements. Commented on the effect of Li-ion solvation and hydrogen bonding interaction on the electrochemical properties of a Li-ion battery.

description: A nematic transition preceding a long-range spin density wave antiferromagnetic phase is a common feature of many Fe based superconductors. However, in the FeSe system with a nematic transition at $T_{\rm s} \approx$ 90 K no evidence for long-range static magnetism down to very low temperature was found. The lack of magnetism is a challenge for the theoretical description of FeSe. Here, we investigated high-quality single crystals of FeSe using high-field (up to 9.5 Tesla) muon spin rotation ($μ$SR) measurements. The $μ$SR Knight shift and the bulk susceptibility linearly scale at high temperatures but deviate from this behavior around $T^{*} \sim 10$ K, where the Knight shift exhibits a kink. This behavior hints to an essential change of the electronic and/or magnetic properties crossing the region near $T^{*}$. In the temperature range $T_{\rm s} \gtrsim T \gtrsim T^{*}$ the muon spin depolarization rate follows a critical behavior $Λ\propto T^{-0.4}$. The observed non-Fermi liquid behavior with a cutoff at $T^{*}$ indicates that FeSe is in the vicinity to a antiferromagnetic quantum critical point. Our analysis is suggestive for $T^{*}$ triggered by the Lifshitz transition.

description: We present a comparison between the SCUBA Half Degree Extragalactic Survey (SHADES) at 450 and 850 microns in the Lockman Hole East with a deep Spitzer Space Telescope survey at 3.6-24 microns conducted in Guaranteed Time. Using stacking analyses we demonstrate a striking correspondence between the galaxies contributing the submm extragalactic background light, with those likely to dominate the backgrounds at Spitzer wavelengths. Using a combination BRIzK plus Spitzer photometric redshifts, we show that at least a third of the Spitzer-identified submm galaxies at 1 and specific star formation rates are in striking disagreement with some semi-analytic predictions from the Millenium simulation. The discrepancy could either be resolved with a top-heavy initial mass function, or a significant component of the submm flux heated by the interstellar radiation field.

description: In this paper we explore the effects of 3.5 MeV proton irradiation on Fe(Se,Te) thin films grown on CaF2. In particular, we carry out a systematic experimental investigation with different irradiation fluences up to 7.30x10^16 cm^-2 and different proton implantation depths, in order to clarify whether and to what extent the critical current is enhanced or suppressed, what are the effects of irradiation on the critical temperature, the resistivity and the critical magnetic fields, and finally what is the role played by the substrate in this context. We find that the effect of irradiation on superconducting properties is generally small as compared to the case of other iron-based superconductors. Such effect is more evident on the critical current density Jc, while it is minor on the transition temperature Tc, on the normal state resistivity and on the upper critical field Hc2 up to the highest fluences explored in this work. In addition, our analysis shows that when protons implant in the substrate far from the superconducting film, the critical current can be enhanced up to 50% of the pristine value at 7 T and 12 K, while there is no appreciable effect on critical temperature and critical fields together with a slight decrease in resistivity. On the contrary, when the implantation layer is closer to the film-substrate interface, both critical current and temperature show a decrease accompanied by an enhancement of the resistivity and the lattice strain. This result evidences that possible modifications induced by irradiation in the substrate may affect the superconducting properties of the film via lattice strain. The robustness of the Fe(Se,Te) system to irradiation induced damage makes it a promising compound for the fabrication of magnets in high-energy accelerators.

description: Turbulence in the quantum (superfluid) regime, similarly to its classical counterpart, continues to attract a great deal of scientific inquiry, due to the yet high number of unresolved problems. While turbulent states can be routinely created in degenerate atomic gases, there is no generic scheme to produce turbulence in fluids of light. Under paraxial propagation, light in bulk nonlinear media behaves as a two-dimensional superfluid, described by a nonlinear Schrödinger equation formally equivalent to the Gross-Pitaevskii model of a weakly interacting Bose gas, where photon-photon interactions are mediated by a third order (Kerr) nonlinearity. Here, we develop the theory describing the onset of a kinetic instability when two paraxial optical fluids with different streaming velocities interact via the optical nonlinearity. From numerical simulations of the nonlinear Schrödinger equation, we further characterize the onset of the instability and describe its saturation in the form of vortex nucleation and excitation of turbulence. The experimental observation of such effects is also discussed. The class of instabilities described here thus provide a natural route towards the investigation of quantum (superfluid) turbulence, structure formation and out-of-equilibrium dynamics in superfluids of light.

ELIXIR is a European research infrastructure, bringing together scientists from 25 countries and over 250 research institutes to enable researchers to access and analyse life science data. Both its organisation and its infrastructure are distributed and federated; the UK node itself has 28 member organisations, including HDR UK. What can HDR UK learn from ELIXIR’s ways of working? How might HDR UK use ELIXIR’s tools and technologies? How can HDR UK benefit from ELIXIR’s work in trans-national Human Genomics and Translational Data?

In this talk I present ELIXIR from the point of view of its community complexity and the mechanisms used to convene its software community to in turn convene a technology ecosystem for infrastructure. Three themes: Trust, Thrust and Transparency.  Five “rules”: (1) Drivers with Dedicated effort & Group identity; (2) Open & Opportunities Culture -> Joint Ownership Everywhere, Everyone, All the Time; (3) Sense of Belonging & Getting Stuff Done; Clarity on the Mission. (4) Not the same as Control (5) Directly Couple Developers & Users on real Example; Solutions, not bags of technology. Don’t decouple.

description: This is the pre-published version harvested from ArXiv. The published version is located at http://iopscience.iop.org/1538-3881/136/1/479/
description: Spitzer Infrared Array Camera (IRAC) observations of two fields in the extended UV disk (XUV-disk) of M83 have been recently obtained, ~3 R HII away from the center of the galaxy (R HII = 6.6 kpc). Galaxy Evolution Explorer (GALEX) UV images have shown the two fields to host in situ recent star formation. The IRAC images are used in conjunction with GALEX data and new H I imaging from The H I Nearby Galaxy Survey (THINGS) to constrain stellar masses and ages of the UV clumps in the fields, and to relate the local recent star formation to the reservoir of available gas. Multi-wavelength photometry in the UV and mid-IR (MIR) bands of 136 UV clumps (spatial resolution >220 pc) identified in the two target fields, together with model fitting of the stellar UV-MIR spectral energy distributions (SEDs), suggests that the clumps cover a range of ages between a few Myr and >1 Gyr with a median value around ≤100 Myr, and have masses in the range 103-3 × 106 M , with a peak . The range of observed ages, for which only a small fraction of the mass in stars appears to have formed in the past ~10 Myr, agrees with the dearth of Hα emission observed in these outer fields. At the location of our IRAC fields, the H I map shows localized enhancement and clumping of atomic gas. A comparison of the observed star formation with the gas reservoir shows that the UV clumps follow the Schmidt-Kennicutt scaling law of star formation, and that star formation is occurring in regions with gas densities at approximately (within a factor of a few) the critical density value derived according to the Toomre Q gravitational stability criterion. The significant 8 μm excess in several of the clumps (16% of the total by number accounting for ~67% of the 8 μm flux) provides evidence for the existence of dust in these remote fields, in agreement with results for other galaxies. Furthermore, we observe a relatively small excess of emission at 4.5 μm in the clumps (14% ± 6% by flux), which suggests contribution from hot small grains (~1000 K), as already observed in other galaxies. From our data, the outer regions of the M83 galaxy disk show evidence of a time-extended star-formation history over 1 Gyr, and of a moderately chemically-evolved interstellar medium, in agreement with recent findings on the metallicity of the outer H II regions of M83.

description: Science increasingly depends on software. From configuration and control of instruments, to statistical analysis, simulation and visualization, virtually every workflow that generates scientific results involves software.1 In practice, scientific collaboration in a growing number of disciplines means drawing together different software artifacts produced in different ways, by different people, to build an ensemble artifact that does scientific work and, ultimately, provides reasons to believe scientific conclusions. In this position paper we present an understanding of the scientific software development ecosystem that is emerging from our interviews of working scientists who develop software in the course of their science. First we describe the types of software and software development being undertaken. We then focus in on three logics of correctness that have emerged from our interviews. We demonstrate that these logics are closely linked to the social circumstances of the software’s production and use and the type of software; these are socio-technical logics. We conclude by examining the implications of this understanding for shaping policies designed to maximize the return on the substantial public investments in scientific software production.
A Qualitative Examination of Adaptations in Social and Emotional Learning (SEL) Programs
Creators: name: Lovett, Joshua McKinley
Publisher: name: University of Illinois at Chicago
Year: 2024

description: Social and emotional learning (SEL) has become a wide-ranging topic in the field of education. Although the field of SEL has experienced rapid growth in the past two decades, research on the ways in which SEL programs are implemented has often lagged behind. Researchers in the field have begun to examine some aspects of implementation in detail, such as fidelity and dosage, but other aspects — particularly adaptation — have gone unexplored despite scholarly recommendations to probe this salient component of implementation. Using secondary qualitative data from two randomized controlled trials of SEL programs implemented with elementary and middle school students, this study examined the ways teachers adapted the SEL lessons and the reasons they made adaptations. Findings revealed that teachers made a variety of adaptations, including structural adaptations (i.e., changes to content, sequencing, and timing) and process adaptations (i.e., adaptations made to how the lesson was delivered and experienced). Teachers also described reasons for adapting that were broadly due to student factors, program factors, and contextual factors. Differences between the two programs are also addressed. These results shed light on the numerous ways in which teachers adapt SEL programs and the array of complex reasons that lead to adaptation of lessons within these types of programs. Given that adaptation is vastly understudied in SEL interventions, this study lays the groundwork for future work to build upon.

description: HSBooster.eu organised its second Deep-Dive Workshop Series, focusing on "AI Standardisation: Challenges & Opportunities on Advancing Equity & Ethics in AI," on 4 July 2024 from 11:00 to 12:30 CEST. This workshop series was organised in collaboration with two HSBooster’s EPE experts in AI, which entail that the newest circular economy initiatives in Europe must demand that nearly all products sold in the EU comply with a wide range of sustainability requirements that ensure transparency about all stages of a product’s life cycle.

AI ethics involves addressing the moral and societal implications of artificial intelligence technologies. Standardisation plays a crucial role in this domain by establishing guidelines and frameworks to ensure that AI systems are developed, deployed, and used in a responsible and ethical manner. Standardisation efforts focus on promoting transparency, fairness, accountability, and privacy in AI applications, ultimately aiming to mitigate potential risks and maximise the benefits of AI for society.

This workshop provides an overview of the standards already developed or being developed in AI Ethics and examples of project results, showcasing their frameworks.

description: We present a class of dynamical solutions for intersecting D4-D8 and D3-D7 brane systems in ten-dimensional type IIA and IIB supergravity. We discuss if these solutions can be recovered in lower-dimensional effective theories for the warped compactification of a general p-brane system. It is found that an effective $p+1$-dimensional description is not possible in general due to the entanglement of the transverse coordinates and the $p+1$-dimensional coordinates in the metric components. For the D4-D8 brane system, the dynamical solutions reduces to a static warped ${\rm AdS_6}\times {\rm S}^4$ geometry in a certain spacetime region. For the D3-D7 brane system, we find a dynamical solution whose metric form is similar to that of a D3-brane solution. The main difference is the existence of a nontrivial dilaton configuration in the D3-D7 solution. Then we discuss cosmology of these solutions. We find that they behave like a Kasner-type cosmological solution at $τ\to\infty$, while it reduces to a warped static solution at $τ\to0$, where $τ$ is the cosmic time.

Especially the irreducible nonabelian configurations seem to have the maximal angular momentum of order $N^3$, beyond which they collapse to abelian ones. We also find some new BPS configurations explicitly.

description: We present a theoretical scheme for multistability in planar microcavity exciton-polariton condensates under nonresonant driving. Using an excitation profile resulting in a spatially patterned condensate, we observe organized phase locking which can abruptly reorganize as a result of pump induced instability made possible by nonlinear interactions. For $π/2$ symmetric systems this reorganization can be regarded as a parity transition and is found to be a fingerprint of multistable regimes existing over a finite range of excitation strengths. The natural degeneracy of the planar equations of motion gives rise to parity bifurcation points where the condensate, as a function of excitation intensity, bifurcates into one of two anisotropic degenerate solutions. Deterministic transitions between multistable states are made possible using controlled nonresonant pulses, perturbing the solution from one attractor to another.

description: Development requires learning skills using previously learned skills as building blocks. For maximum flexibility, the developing agent should be able to learn these skills without being provided an explicit task or subtasks. We have developed a method that allows an agent to simultaneously learn hierarchical actions and important distinctions autonomously without being specified a task. This ability to learn new distinctions allows it to work in continuous environments, and allows an agent to learn its first actions from motor primitives. In this paper we demonstrate that our method can use experience from one set of variables to more quickly learn a task that requires additional new variables. It does this by learning actions in a developmental progression. In addition, we demonstrate this developmental progression by showing that actions that are mainly used for exploration when first learned are later used as subactions for other actions.

Our estimates are within 5-10 percent from the conjectured value of the universal spectrum.

description: The effect of heavy tar compounds on the performance of a Ni-YSZ anode supported solid oxide fuel cell was investigated. Both toluene and naphthalene were chosen as model compounds and tested separately with a simulated bio-syngas. Notably, the effect of naphthalene is almost negligible with pure H2 feed to the SOFC, whereas a severe degradation is observed when using a bio-syngas with an H2:CO = 1. The tar compound showed to have a remarkable effect on the inhibition of the WGS shift-reaction, possibly also on the CO direct electro-oxidation at the three-phase-boundary. An interaction through adsorption of naphthalene on nickel catalytic and electrocatalytic active sites is a plausible explanation for observed degradation and strong performance loss. Different sites seem to be involved for H2 and CO electro-oxidation and also with regard to catalytic water gas shift reaction. Finally, heavy tars (C>=10) must be regarded as a poison more than a fuel for SOFC applications, contrarily to lighter compounds such benzene or toluene that can directly reformed within the anode electrode. The presence of naphthalene strongly increases the risk of anode re-oxidation in a syngas stream as CO conversion to H2 is inhibited and also CH4 conversion is blocked.

description: Intrathecal drug (IT) delivery can efficiently target regions in the central nervous system without hindering the blood-brain barrier. This delivery mode is especially promising for novel therapeutics such as enzyme replacement, gene, or antisense oligonucleotide (ASO) therapies for treating neurodegenerative diseases, including Alzheimer’s, Huntington’s disease, and stroke. Due to the high risk to patients and technical limitations of acquiring high-speed cerebrospinal fluid (CSF) flow and bio-distribution data with existing imaging modalities (e.g., MRI, PET) in humans in vivo, the study cannot be performed. A novel, fast, relatively economical, and subject-specific in-vitro method to study the drug bio-dispersion mechanism and optimize IT drug therapies for individual patients is in great need. This method of drug delivery has been studied using experiments, with the use of a manufactured in vitro model of the human spine, which is subjected to the effect of pulsation as experienced in the actual human spine, and computational approaches. Model design and additive manufacturing process for producing a subject-specific spine that replicates the interaction of the human spine with the CSF has been presented. A numerical solution was developed to solve the 1D diffusion problem to generate and compare the concentration profile with those obtained experimentally. Also, to understand how drug can be targeted in the central nervous system (CNS), magnetophoresis – movement of paramagnetic nanoparticles in the presence of external magnetic field, was also studied. Analytical solutions to the magnetic field-driven transport of particles in 1-D and 3D were developed with application to drug delivery through cerebrospinal fluid. This solution gives rise to concentration profiles of the paramagnetic nanoparticle. The results obtained from our models and experiment show that the manufactured spine is functional and can be utilized for optimizing drug dosing guidelines for IT administration before human trials and as a complement or substitute for animal trials. The computational results also provide confidence in the in-vitro experiments as the results are comparable. The developed magnetophoresis model and experiment show that paramagnetic nanoparticle can be confined in a particular domain of the central nervous system (CNS) which will aid the delivery and targeting of drug to the domain.

description: The statistical problem for network tomography is to infer the distribution of $\mathbf{X}$, with mutually independent components, from a measurement model $\mathbf{Y}=A\mathbf{X}$, where $A$ is a given binary matrix representing the routing topology of a network under consideration. The challenge is that the dimension of $\mathbf{X}$ is much larger than that of $\mathbf{Y}$ and thus the problem is often called ill-posed. This paper studies some statistical aspects of network tomography. We first address the identifiability issue and prove that the $\mathbf{X}$ distribution is identifiable up to a shift parameter under mild conditions. We then use a mixture model of characteristic functions to derive a fast algorithm for estimating the distribution of $\mathbf{X}$ based on the General method of Moments. Through extensive model simulation and real Internet trace driven simulation, the proposed approach is shown to be favorable comparing to previous methods using simple discretization for inferring link delays in a heterogeneous network.

description: For a general three dimensional theory of (super-)gravity coupled to arbitrary matter fields with arbitrary set of higher derivative terms in the effective action, we give an algorithm for consistently truncating the theory to a theory of pure (super-)gravity with the gravitational sector containing only Einstein-Hilbert, cosmological constant and Chern-Simons terms. We also outline the procedure for finding the parameters of the truncated theory. As an example we consider dimensional reduction on S^2 of the 5-dimensional minimal supergravity with curvature squared terms and obtain the truncated theory without any curvature squared terms. This truncated theory reproduces correctly the exact central charge of the boundary CFT.

A Systematic Study on Direct Photon Production from Central Heavy Ion Collisions

description: We investigate the production of direct photons in central Au-Au collisions at the relativistic Heavy-Ion Collider (RHIC) at 200 GeV per nucleon, considering all possible sources. We treat thermal photons emitted from a quark-gluon plasma and from a hadron gas, based on a realistic thermodynamic expansion. Hard photons from elementary nucleon-nucleon scatterings are included: primordial elementary scatterings are certainly dominant at large transverse momenta, but also secondary photons from jet fragmentation and jet-photon conversion cannot be ignored. In both cases we study the effect of energy loss, and we also consider photons emitted from bremsstrahlung gluons via fragmentation.

description: We investigate yttrium iron garnet (YIG)/cobalt (Co) heterostructures using broadband ferromagnetic resonance (FMR). We observe an efficient excitation of perpendicular standing spin waves (PSSWs) in the YIG layer when the resonance frequencies of the YIG PSSWs and the Co FMR line coincide. Avoided crossings of YIG PSSWs and the Co FMR line are found and modeled using mutual spin pumping and exchange torques. The excitation of PSSWs is suppressed by a thin aluminum oxide (AlOx) interlayer but persists with a copper (Cu) interlayer, in agreement with the proposed model.

description: As programming skills increase in demand and utility, the learnability of end-user programming systems is of utmost importance. However, research on learning barriers in programming systems has primarily focused on languages, overlooking potential barriers in the environment and accompanying libraries. To address this, a study of beginning programmers learning Visual Basic.NET was performed. This identified six types of barriers: design, selection, coordination, use, understanding, and information. These barriers inspire a new metaphor of computation, which provides a more learner-centric view of programming system design.

description: We investigated the time-dependent polarization switching behaviors of (111)-preferred polycrystalline Pb(ZrxTi1-x)O3 thin films with various Zr concentrations. We could explain all the polarization switching behaviors well by assuming Lorentzian distributions in the logarithmic polarization switching time [Refer to J. Y. Jo et al., Phys. Rev. Lett. (in press)]. Based on this analysis, we found that the Zr ion-substitution for Ti ions would induce broad distributions in the local field due to defect dipoles, which makes the ferroelectric domain switching occur more easily.

description: Algorithms for 3D robotic visual tracking of moving targets whose motion is 3D and consists of translational and rotational components are presented. The objective of the system is to track selected features on moving objects and to place their projections on the image plane at desired positions by appropriate camera motion. The most important characteristics of the proposed algorithms are the use of a single camera mounted on the end-effector of a robotic manipulator (eye-in-hand configuration), and the fact that these algorithms do not require accurate knowledge of the relative distance of the target object from the camera frame. This fact makes these algorithms particularly useful in environments that are difficult to calibrate. The camera model used introduces a number of parameters that are estimated on-line, further reducing the algorithms’ reliance on precise calibration of the system. An adaptive control algorithm compensates for modeling errors, tracking errors, and unavoidable computational delays which result from time-consuming image processing. Experimental results are presented to verify the efficacy of the proposed algorithms. These experiments were performed using a multi-robotic system consisting of Puma 560 manipulators.
