description: Objectives: The study objectives were to examine: (1) adolescents’ media viewing habits, (2) associations with media viewing and self-reported exposure to unhealthy food and beverage advertising and (3) differences in trends among younger and older adolescents in six high and upper middle-income countries. Design: Repeat cross-sectional online survey. Setting: Australia, Canada, Chile, Mexico, the United Kingdom (UK) and the United States of America (USA). Participants: Respondents to the International Food Policy Study who provided information on all variables of interest in November–December 2019 aged 10–17 years (n=9171). Outcome: measures Self-reported exposure to screen-based media (screen time by media channel), use of social media platforms and self-reported location and frequency of exposure to unhealthy food and beverage advertising. Results: The average amount of time spent in front of various screens ranged from 7.6 hours to 10.2 hours across countries per week day, which may include possible viewing of multiple media channels simultaneously. Overall, Instagram was the most popular social media platform (52%–68% by country), followed by Facebook (42%–79%) and Snapchat (28%–52%). The percentage of respondents who self-reported having seen unhealthy food advertisements in the past 30 days was highest on television (43%–69%), followed by digital media (27%–60%) and gaming applications (10%–17%). Self-reported daily exposure to advertising varied between countries for sugary drinks (10%–43%) and fast food (19%–44%) and was positively associated with self-reported screen time. Self-reported exposure to screen-based media and social media platforms differed by sociodemographic characteristics and was higher among older adolescents than younger adolescents. Conclusions: The important amount of time spent on screen-based media reported by adolescents and large percentage of adolescents reporting social media usage, coupled with high rates of self-reported advertising exposure, support the need for policies to restrict marketing of unhealthy food and beverages appealing to adolescents on screen-based media.

description: We examined the fate and behaviour of diluted bitumen (dilbit) as it weathered for 70 days in freshwater limnocorrals (10 m diameter × 1.5 m depth) installed in a boreal lake to simulate dilbit spills in a natural aquatic environment. We added seven different dilbit spill volumes, ranging from 1.5 to 180 L, resulting in oil-to-water ratios between 1:71,000 (v/v, %) and 1:500 (v/v, %). Volatile hydrocarbons in the dilbit slick decreased rapidly after the dilbit was spilled on the water's surface, and dilbit density and viscosity significantly increased (>1 g mL-1 and >5,000,000 mPa s, respectively). Dilbit sank to the bottom sediments in all treatments, and the time to sinking was positively correlated with spill volume. The lowest dilbit treatment began to sink on day 12, whereas the highest dilbit treatment sank on day 31. Dilbit submerged when its density surpassed the density of freshwater (>0.999 g mL-1), with wind, rain, and other factors contributing to dilbit sinking by promoting the break-up of the surface slick. This experiment improves our ability to predict dilbit's aquatic fate and behaviour, and its tendency to sink in a boreal lake. Our findings should be considered in future pipeline risk assessments to ensure the protection of these important aquatic systems.
title: Interspecies Interactions Between the Nematode Pristionchus pacificus and Bacterial Food Sources

description: The past few decades biological research has turned its attention towards the interspecies interactions taking place between multicellular organisms and their associated microbial communities. The focus has been placed mainly on symbiotic prokaryotes and their ability to modulate their host’s physiological traits and responses, with the most representative example belonging to the field of human gut microbiome research. While currently popular, these interactions consist only a fraction of the inter- and intra-species relationships within a given niche. Ecological communities are often represented as complex networks, in an attempt to illustrate the multifaceted interplay present as well as the communication between the interacting partners that may determine their evolutionary trajectories and influence their adaptation. The study of such systems depends on the ability to establish simple but representative proxies. Nematodes, such as Pristionchus pacificus, and their diverse environment possess an array of properties that deem them an excellent choice to study interspecies interactions. During the last years, we have gathered important information regarding the effect of bacterial diets on P. pacificus’ behavior along with the worm’s impact on the associated bacterial communities. My work aims to broaden the scope of the questions and hypotheses formed, from specific genes or traits to entire regulatory networks as well as outline the importance of the information harnessed from the bacteria itself. To this end, I initially reconstructed the phylogeny and identified the metabolic potential of a subset of bacteria isolated from Pristionchus- associated environments in previous studies. This strategy allowed me to uncover the variation of the predicted metabolic potential across the phylogeny, detect genus- specific metabolic signatures in the bacterial strains and associate them with nematode traits from previous works. Furthermore, I identified environmentally responsive regulatory networks in P. pacificus through the implementation of a gene co-expression network constructed with transcriptomic profiles of the nematode and almost half of the sequenced bacterial strains as a dietary source. Lastly, I combined the collected data both from the bacteria and the nematode in a bipartite network and revealed the bacterial metabolic pathways with the strongest effect on the worm’s regulatory networks. Overall, my work explores the interspecies interactions between P. pacificus and bacterial food sources and offers novel insights on a larger scale.

description: Active triggering and manipulation of ultrafast flux dynamics in superconductors are demonstrated in films of Nb. Controlled amounts of magnetic flux were injected from a point along the edge of a square sample, which at 2.5 K responds by nucleation of a thermomagnetic avalanche. Magneto-optical imaging was used to show that when such films are cooled in the presence of in-plane magnetic fields they become anisotropic, and the morphology of the avalanches change systematically, both with the direction and magnitude of the field. The images reveal that the avalanching dendrites consistently bend towards the direction perpendicular to that of the in-plane field. The effect increases with the field magnitude, and at 1.5 kOe the triggered avalanche becomes quenched at the nucleation stage. The experimental results are explained based on a theoretical model for thermomagnetic avalanche nucleation in superconducting films, and by assuming that the frozen-in flux generates in-plane anisotropy in the film thermal conductance. The results demonstrate that applying in-plane magnetic fields to film superconductors can be a versatile external tool for controlling their ultrafast flux dynamics.
Belief Propagation Reveals Allosteric Mechanisms in Proteins

description: The physical mechanisms involved in allosteric regulation remain unclear. We present a novel and efficient method for investigating the propagation of regulatory signals in protein structures. Our approach utilizes undirected graphical models to efficiently encode the Boltzmann distribution over geometric configurations. Belief Propagation is then invoked to efficiently compute: (a) free energies and (b) allosteric couplings between distal residues. We present results from two kinds of experiments. First, we show that our method accurately predicts changes in free energy upon activation and/or mutation. Specifically, our method achieves a high correlation with experimentally determined ΔΔGs (R2 = 0.90 for core residues). Significantly, our method is capable of identifying those residues experiencing the largest relative changes in enthalpy and/or entropy. Second, we use our method to study the allosteric behavior of cyclophilin A in enzyme catalysis. Our analysis reveals the allosteric coupling between residues separated by as much as 20 angstroms from the active site. These results correspond well with experimental measurements. Our method requires a few minutes per protein, making it suitable for large-scale studies. Taken together, these results suggest that our method provides an effective means for investigating allosteric regulation at the proteome scale.

description: We combine Sullivan models from rational homotopy theory with Stasheff's $L_\infty$-algebras to describe a duality in string theory. Namely, what in string theory is known as topological T-duality between $K^0$-cocycles in type IIA string theory and $K^1$-cocycles in type IIB string theory, or as Hori's formula, can be recognized as a Fourier-Mukai transform between twisted cohomologies when looked through the lenses of rational homotopy theory. We show this as an example of topological T-duality in rational homotopy theory, which in turn can be completely formulated in terms of morphisms of $L_\infty$-algebras.

description: The movement of fish in watersheds is frequently inhibited by human-made migration barriers such as dams or culverts. The resulting lack of connectivity of spatial subpopulations is often cited as a cause for observed population decline. We formulate a matrix model for a spatially distributed fish population in a watershed, and we investigate how location and other characteristics of a single movement barrier impact the asymptotic growth rate of the population. We find that while population growth rate often decreases with the introduction of a movement obstacle, it may also increase due to a 'retention effect'. Furthermore, obstacle mortality greatly affects population growth rate. In practice, different connectivity indices are used to predict population effects of migration barriers, but the relation of these indices to population growth rates in demographic models is often unclear. When comparing our results with the dentritic connectivity index, we see that the index captures neither the retention effect nor the influences of obstacle mortality. We argue that structural indices cannot entirely replace more detailed demographic models to understand questions of persistence and extinction. We advocate the development of novel functional indices and characteristics.

description: We propose to use the energy absorption spectroscopy to measure the kinetic coefficients of unitary Fermi gases in a uniform potential. We show that in our scheme, the energy absorption spectrum is proportional to the dynamic structure factor of the system. The profile of the spectrum depends on the shear viscosity $η$, the thermal conductivity $κ$ and the superfluid bulk viscosity $ξ_3$. We show that extraction of these coefficients from the spectrum is achievable in present experiments.

Behavioral Polymorphism and Parametricity in Session-Based Communication

description: We investigate a notion of behavioral genericity in the context of session type disciplines. To this end, we develop a logically motivated theory of parametric polymorphism, reminiscent of the Girard-Reynolds polymorphic λ-calculus, but casted in the setting of concurrent processes. In our theory, polymorphism accounts for the exchange of abstract communication protocols and dynamic instantiation of heterogeneous interfaces, as opposed to the exchange of data types and dynamic instantiation of individual message types. Our polymorphic session-typed process language satisfies strong forms of type preservation and global progress, is strongly normalizing, and enjoys a relational parametricity principle. Combined, our results confer strong correctness guarantees for communicating systems. In particular, parametricity is key to derive non-trivial results about internal protocol independence, a concurrent analogous of representation independence, and non-interference properties of modular, distributed systems.

description: We have made pressure and NMR measurements during the evolution of phase separation in solid helium isotopic mixtures. Our observations indicate clearly all three stages of the homogeneous nucleation - growth process: 1) creation of nucleation sites; 2) growth of the new-phase component at these nucleation sites; and 3) coarsening: the dissolution of sub-critical droplets with the consequent further late-stage growth of the super-critical droplets. The time exponent for the coarsening, a = 1/3, is consistent with the conserved order parameter Lifshitz-Slezov evaporation-condensation mechanism.

description: Signatures of nodal line/point superconductivity have been observed in half-Heusler compounds, such as LnPtBi (Ln = Y, Lu). Topologically non-trivial band structures, as well as topological surface states, has also been confirmed by angular-resolved photoemission spectroscopy in these compounds. In this work, we present a systematical classification of possible gap functions of bulk states and surface states in half-Heusler compounds and the corresponding topological properties based on the representations of crystalline symmetry group. Different from all the previous studies based on four band Luttinger model, our study starts with the six-band Kane model, which involves both four p-orbital type of Γ8 bands and two s-orbital type of Γ6 bands. Although the Γ6 bands are away from the Fermi energy, our results reveal the importance of topological surface states, which originate from the band inversion between Γ6 and Γ8 bands, in determining surface properties of these compounds in the superconducting regime by combining topological bulk state picture and non-trivial surface state picture.
Photodissociation dynamics in the first absorption band of pyrrole: I. Molecular Hamiltonian and the Herzberg-Teller absorption spectrum for the $1^1A_2(πσ^*) \leftarrow \tilde{X}^1A_1(ππ)$ transition

description: This paper opens a series in which the photochemistry of the two lowest $πσ^*$ states of pyrrole and their interaction with each other and with the ground electronic state $\tilde{X}$ are studied using ab initio quantum mechanics. New 24-dimensional potential energy surfaces for the photodissociation of the N-H bond and the formation of the pyrrolyl radical are calculated using the CASPT2 method for the electronic states $\tilde{X}(ππ)$, $1^1A_2(πσ^*)$ and $1^1B_1(πσ^*)$ and locally diabatized. In the first paper, the ab initio calculations are described and the photodissociation in the state $1^1A_2(πσ^*)$ is analyzed. The excitation $1^1A_2 \leftarrow \tilde{X}$ is mediated by the coordinate dependent transition dipole moment functions constructed using the Herzberg-Teller expansion. Nuclear dynamics, including 6, 11, and 15 active degrees of freedom, is studied using the multi-configurational time-dependent Hartree method. The focus is on the frequency resolved absorption spectrum, as well as on the dissociation time scales and the resonance lifetimes. Calculations are compared with available experimental data. An approximate convolution method is developed and validated, with which absorption spectra can be calculated and assigned in terms of vibrational quantum numbers. The method represents the total absorption spectrum as a convolution of the diffuse spectrum of the detaching H-atom and the Franck-Condon spectrum of the heteroaromatic ring. Convolution calculation requires a minimal quantum chemical input and is a promising tool for studying the $πσ^*$ photodissociation in model biochromophores.

description: The redshifted $21$\,cm signal of neutral hydrogen can be used as a direct probe of the intergalactic medium during Cosmic Dawn\,(CD) and Epoch of Reionization\,(EoR). However, detecting this inherently weak signal has numerous challenges. The major ones include accurate foreground removal from low-frequency radio observations and systematics arising from instrumental effects. The Earth's ionosphere poses a major obstacle at these low radio frequencies. Thus, a systematic study of ionospheric effects on these sensitive low-frequency observations is critical, given that the construction of the Square Kilometre Array (SKA1-Low) is in full progress. We use the end-to-end pipeline, called {\sc 21cme2e}, to study the effect of time-varying ionospheric corruption on the $21$\,cm power spectrum recovery. We use two models: a) a catalogue-based model focused on source position shift due to the refractive effect of the ionosphere and b) a realistic ionospheric condition generated using Kolmogorov's turbulence model. We assess the effect of the imperfections thus generated on the extraction of \HI\ $21$\,cm signal power spectrum. Our study shows that beyond ``median ionospheric offset" ($θ_{\text{MIO}} \lesssim 0.1''$), the $21$\,cm signal from the EoR is unaffected by residual ionospheric effects. Our study emphasizes the need for the development of efficient ionospheric calibration algorithms for the upcoming SKA1-Low observations to extract the \HI\ $21$\,cm power spectra from the CD/EoR.

description: We investigated the electroluminescent properties of the epitaxial graphene/SiC junction. The temperature and current dependence of electroluminescence from the epitaxial graphene/SiC is measured within a temperature range of 50-300 K. The result of electroluminescence at 300~K is compared with the electroluminescent spectra from aluminium/SiC junction. The difference between the spectra is explained by the different band bending, which could lead to the tunable LED due to the semi-metal character of the graphene. We observed the electroluminescence at both bias polarities and we described the blue shift in the spectra by Franz-Keldysh effect.

In particular, the rate of relaxation may either increase or decrease exponentially compared to the unperturbed case. This implies that disorder may, depending on its properties, both significantly speed up \textit{and} slow down relaxation. In the limit of weak disorder, we derive the probability distribution of the asymptotic relaxation rate and show that it is Gaussian, with analytic expressions for the mean and variance that feature universal limits. Our findings indicate that controlled disorder may serve to tune the relaxation speed in complex systems.

description: We consider a recently proposed generalization of unimodular gravity, where the lapse function is constrained to be equal to a function of the determinant of the spatial metric $f(h)$, as a potential origin of a dark fluid with a generally $h$-dependent equation of state parameter. We establish the Hamiltonian analysis and the canonical path integral for the theory. All the special cases that do not match unimodular gravity involve violation of general covariance, and consequently the physical content of the theory is changed significantly. Particularly, the case of a constant function $f$ is shown to contain an extra physical degree of freedom in each point of space. Physical consequences of the extra degree of freedom are studied in a linearized theory, where the extra mode is carried by the trace of the metric perturbation. The trace mode does not propagate as a wave, since it satisfies an elliptic partial differential equation in spacetime. Consequently, the trace perturbation is shown to grow exponentially with time, which implies instability. The case of a general $f(h)$ involves additional second-class constraints, which implies the presence of an extra global degree of freedom that depends only on time (instead of the extra local degree of freedom in the case of a constant $f$).

description: Aktuell bleibt es weiterhin eine Herausforderung für Bibliotheken, durch die sich weiterentwickelnden, technischen Möglichkeiten in der Forschung, die Umsetzung virtueller Arbeitsumgebungen für die Wissenschaft, zu realisieren. Die Bereitstellung von Forschungsdaten, u.a. in Form der FAIR-Prinzipien, stellen Anforderungen an die Qualität und den Umfang der Metadaten dar, die wiederum dazu beitragen, die Qualität der gesamten Forschung oder eines Forschungsprojektes zu sichern. Forscherinnen und Forscher kümmern sich teilweise, aus verschiedenen Gründen, zu wenig um ein gutes Metadatenmanagement! Oft bleiben geeignete Standards unberücksichtigt, was vielleicht daran liegen könnte, dass Bibliotheken sie zu wenig lehren (Klassifikationssysteme, Kontrollierte Vokabulare), und es Systeme gibt, die über die bibliografischen Systeme, beziehungsweise deskriptive Metadaten, hinausgehen. Ein einfacher Verweis auf Plattformen zum FDM mit dem Kapitel 'Metadaten' ist für Forschende nicht ausreichend, um verstehen zu können, was ein Umgang mit Metadaten bedeutet. Im Zusammenhang mit der Langzeitarchivierung - als ein integraler Bestandteil des Forschungsdatenmanagement - spielen sie und Metadatenstandards, wie wir wissen, aber eine wesentliche Rolle (Metadateninteroperabilität).

description: We introduce p-1 pseudocharacters in the space of (1,p) model vacuum torus amplitudes to complete the distinguished basis in the 2p-dimensional fusion algebra to a basis in the whole (3p-1)-dimensional space of torus amplitudes, and the structure constants in this basis are integer numbers. We obtain a generalized Verlinde-formula that gives these structure constants. In the context of theories with boundaries, we identify the space of vacuum torus amplitudes with the space of Ishibashi states. Then, we propose 3p-1 boundary states satisfying the Cardy condition.

description: Abstract: "We present an algorithm that checks behavioral consistency between an ANSI-C program and a circuit given in Verilog using Bounded Model Checking. Both the circuit and the program are unwound and translated into a formula that is satisfiable if and only if the circuit and the code disagree. The formula is then checked using a SAT solver. We are able to translate C programs that make use of side effects, pointers, dynamic memory allocation, and loops with conditions that cannot be evaluated statically. We describe experimental results on various reactive circuits and programs, including a small processor given in Verilog and its Instruction Set Architecture given in ANSI-C."

description: Based on energy conservation in a Friedmann-Lemaitre-Robertson-Walker (FLRW) Universe, on the Legendre transformation between energy density and pressure, and on nonperturbative asymptotic freedom at high temperatures we derive the coefficient $ν_{\rm CMB}$ in the high-temperature ($T$) -- redshift ($z$) relation, $T/T_0=ν_{\rm CMB}(z+1)$, of the Cosmic Microwave Background (CMB). Theoretically, our calculation relies on a deconfining SU(2) rather than a U(1) photon gas. We prove that $ν_{\rm CMB}=\left(1/4\right)^{1/3}=0.629960(5)$, representing a topological invariant. Interestingly, the relative deviation of $ν_{\rm CMB}$ from the critical exponent associated with the correlation length $l$ of the 3D Ising model, $ν_{\rm Ising}=0.629971(4)$, is less than $2\times 10^{-5}$. We are not yet in a position to establish a rigorous theoretical link between $ν_{\rm CMB}$ and $ν_{\rm Ising}$ as suggested by the topological nature of $ν_{\rm CMB}$ and the fact that both theories share a universality class. We do, however, line out a somewhat speculative map from the physical Ising temperature $θ$ to a fictitious SU(2) Yang-Mills temperature $T$, the latter continuing the asymptotic behavior of the scale factor $a$ on $T/T_0$ for $T/T_0\gg 1$ down to $T=0$, and an exponential map from $a$ to $l$ to reproduce critical Ising behavior.

description: We discuss the dynamics of a quantum phase transition in a spin-1 Bose-Einstein condensate when it is driven from the magnetized broken-symmetry phase to the unmagnetized ``symmetric'' polar phase. We determine where the condensate goes out of equilibrium as it approaches the critical point, and compute the condensate magnetization at the critical point. This is done within a quantum Kibble-Zurek scheme traditionally employed in the context of symmetry-breaking quantum phase transitions. Then we study the influence of the nonequilibrium dynamics near a critical point on the condensate magnetization. In particular, when the quench stops at the critical point, nonlinear oscillations of magnetization occur. They are characterized by a period and an amplitude that are inversely proportional. If we keep driving the condensate far away from the critical point through the unmagnetized ``symmetric'' polar phase, the amplitude of magnetization oscillations slowly decreases reaching a non-zero asymptotic value. That process is described by the equation that can be mapped onto the classical mechanical problem of a particle moving under the influence of harmonic and ``anti-friction'' forces whose interplay leads to surprisingly simple fixed-amplitude oscillations. We obtain several scaling results relating the condensate magnetization to the quench rate, and verify numerically all analytical predictions.

description: The selection rule on vibronic angular momentum of $t_{1u}^n \otimes h_g$ Jahn-Teller problem ($n = $ 1-5) is reinvestigated. It is shown that among three adiabatic orbitals only two have nonzero Berry phase. Thus, the Berry phase of adiabatic electronic configurations depends on the spin multiplicity as well as the number of electrons. On this basis, the general relation between the Berry phase and the angular momentum is described. It allows, in particular, to clarify the nature of vibronic states arising from high spin configurations. In comparison with the previous solution for the low-lying vibronic states for bimodal systems, the present solutions correctly fulfill all the symmetry requirement.

description: Experimental continuation encompasses a set of methods that combine control and continuation to obtain the full bifurcation diagram of a nonlinear system experimentally, including responses that would be unstable in the system without feedback control. Such control-based methods thus allow the experimenter to directly and exhaustively explore the dynamics of the system without the need for a good mathematical model. The objective of this paper is twofold, namely (i) to review and present the state-of-the-art methods in a unified manner and (ii) to introduce a novel experimental derivative-free arclength continuation procedure, termed arclength control-based continuation. These methods are also demonstrated and compared on an electronic Duffing oscillator and a clamped thin plate featuring geometrical nonlinearity. Finally, the current state of the art is reflected upon, and the challenges lying ahead for this growing field are discussed.
