description: We characterize cell motion in experiments and show that the transition to collective motion in colonies of gliding bacterial cells confined to a monolayer appears through the organization of cells into larger moving clusters. Collective motion by non-equilibrium cluster formation is detected for a critical cell packing fraction around 17%. This transition is characterized by a scale-free power-law cluster size distribution, with an exponent $0.88\pm0.07$, and the appearance of giant number fluctuations. Our findings are in quantitative agreement with simulations of self-propelled rods. This suggests that the interplay of self-propulsion of bacteria and the rod-shape of bacteria is sufficient to induce collective motion.

description: In this paper we will try to assess the multifractality displayed by the high-frequency returns of Madrid's Stock Exchange IBEX35 index. A Multifractal Detrended Fluctuation Analysis shows that this index has a wide singularity spectrum which is most likely caused by its long memory. Our findings also show that this long-memory can be considered as the superposition of a high-frequency component (related to the daily cycles of arrival of information to the market), over a slowly-varying component that reverberates for long periods of time and which shows no apparent relation with human economic cycles. This later component is therefore postulated to be endogenous to market's dynamics and to be also the most probable source of some of the stylized facts commonly associated with financial time series.

description: In this paper, we consider an energy-efficient scheduling problem where $n$ jobs $J_1, J_2, ..., J_n$ need to be executed such that the total energy usage of these jobs is minimized while ensuring that each job is finished within it's deadline. We work in an online setting where a job is known only at it's arrival time, along with it's processing volume and deadline. In such a setting, the currently best-known algorithm by Han et al. \cite{han} provides a competitive ratio max $\{4, 2 + α^α\}$ of energy usage. In this paper, we present a new online algorithm SqOA which provides a competitive ratio max $\{4, 2 + (2-1/α)^α2^{α-1}\}$ of energy usage. For $α\geq 3$, the competitive ratio of our algorithm is better than that of any other existing algorithms for this problem.

Long-term Radio Observations of the Intermittent Pulsar B1931+24

description: We present an analysis of approximately 13-yr of observations of the intermittent pulsar B1931+24 to further elucidate its behaviour. We find that while the source exhibits a wide range of nulling (~4-39 d) and radio-emitting (~1-19 d) timescales, it cycles between its different emission phases over an average timescale of approximately 38 d, which is remarkably stable over many years. On average, the neutron star is found to be radio emitting for 26 +- 6 % of the time. No evidence is obtained to suggest that the pulsar undergoes any systematic, intrinsic variations in pulse intensity during the radio-emitting phases. In addition, we find no evidence for any correlation between the length of consecutive emission phases. An analysis of the rotational behaviour of the source shows that it consistently assumes the same spin-down rates, i.e. nudot = -16 +- 1 x 10^-15 s^-2 when emitting and nudot = -10.8 +- 0.4 x 10^-15 s^-2 when not emitting, over the entire observation span. Coupled with the stable switching timescale, this implies that the pulsar retains a high degree of magnetospheric memory, and stability, in spite of comparatively rapid (~ms) dynamical plasma timescales. While this provides further evidence to suggest that the behaviour of the neutron star is governed by magnetospheric-state switching, the underlying trigger mechanism remains illusive. This should be elucidated by future surveys with next generation telescopes such as LOFAR, MeerKAT and the SKA, which should detect similar sources and provide more clues to how their radio emission is regulated.

description: This work studies distributed inference for privacy-non intrusive security applications. Specifically, minimum mean square estimation (MMSE) of channel parameters is proposed, with asynchronous and distributed implementation of Gaussian Belief Propagation (GBP). Wireless channel is measured by distributed wireless terminals/sensors, which exchange messages to infer the wireless channel through asynchronous GBP. Variations of the channel between consecutive measurements indicate the presence (or absence)
of a moving person, without other means (e.g., cameras, microphones or infrared sensors). The method is tested in simulations and compared to synchronous GBP in terms of convergence; in addition, the method is contrasted against centralized least-squares (LS) and centralized MMSE, at the WiFi carrier frequency of 2.4 GHz, at various signal-to-noise ratios. It is found that mobility changes channel estimate metrics by at least one order of magnitude, compared to the static (immobile) case. The method could be exploited in indoor environments, where distributed presence of embedded wireless radios is widespread, without reverting to privacy intrusive microphones or cameras. In addition, the method is truly asynchronous and distributed, and hence more robust compared to synchronous counterparts.

description: Anthropogenic stresses including increased water temperatures, decreased water quality, sea level rise, ocean acidification and sediment biogeochemical processes have caused a significant loss in seagrass meadow acreage. Seagrass meadows provide coastal protection from storms and recently have been emphasized for their importance in sequestering and storing “Blue Carbon” from the atmosphere and ocean. Seagrass meadows can trap this blue carbon in their sediment as organic carbon, and it can be stored for hundreds to thousands of years. Restoration efforts of seagrass meadows in the Virginia coast started in the 1990s and effects of increasing seagrass density can be observed in sediment cores. Three sediment cores were obtained from South Bay within the Virginia Coast in June of 2022. These cores were tested for particle size and organic matter percentage. Finer sediments were found in the top 20 cm of sediment cores with an increase in particle size with depth. Organic matter percentage was highest in shallow sediments and decreased with depth. These observed relationships show that the increase in seagrass density has led to an increase in carbon sequestration in South Bay sediments. Variations in particle size and organic matter percentage with depth may be due to spatial and seasonal differences observed in seagrass meadows.

description: We present boundary conditions for the electromagnetic fields on a δ-function plate, having both electric and magnetic properties, sandwiched between two magneto-electric semi-infinite half spaces. The optical properties for an isolated δ-function plate are shown to be independent of the longitudinal material properties of the plate. The Casimir-Polder energy between an isotropically polarizable atom and a magneto-electric δ-function plate is attractive for a purely electric δ-function plate, repulsive for a purely magnetic δ-function plate, and vanishes for the simultaneous perfect conductor limit of both electric and magnetic properties of the δ-function plate. The interaction energy between two identical δ-function plates is always attractive. It can be attractive or repulsive when the plates have electric and magnetic properties interchanged and reproduces Boyer's result for the interaction energy between perfectly conducting electric and magnetic plates. The change in the Casimir-Polder energy in the presence of a δ-function plate on a magneto-electric substrate is substantial when the substrate is a weak dielectric.

description: We have used Chandra observations of eight bulge-less disk galaxies to identify new ultraluminous X-ray source (ULX) candidates, study their high mass X-ray binary (HMXB) population, and search for low-luminosity active galactic nuclei (AGN). We report the discovery of 16 new ULX candidates in our sample of galaxies. Eight of these are found in the star forming galaxy NGC 337, none of which are expected to be background contaminants. The HMXB luminosity function of NGC 337 implies a star formation rate (SFR) of 6.8$^{+4.4}_{-3.5}$ \msun\ yr$^{-1}$, consistent at 1.5$σ$ with a recent state of the art SFR determination. We also report the discovery of a bright ULX candidate (X-1) in ESO 501-23. X-1's spectrum is well fit by an absorbed power law with $Γ= 1.18^{+0.19}_{-0.11}$ and N$\rm{_H}$ = 1.13$^{+7.07}_{-1.13} \times 10^{20}$ cm$^{-2}$, implying a 0.3-8 keV flux of $1.08^{+0.05}_{-0.07} \times 10^{-12}$ \esc. Its X-ray luminosity (L$_X$) is poorly constrained due to uncertainties in the host galaxy's distance, but we argue that its spectrum implies L$_X > 10^{40}$ \es. An optical counterpart to this object may be present in HST imaging. We also identify ULX candidates in IC 1291, PGC 3853, NGC 5964 and NGC 2805. We find no evidence of nuclear activity in the galaxies in our sample, placing a flux upper limit of $4 \times 10^{-15}$ \esc\ on putative AGN. Additionally, the type II-P supernova SN 2011DQ in NGC 337, which exploded 2 months before our X-ray observation, is undetected.

description: Electronic carriers in graphene show a high carrier mobility at room temperature. Thus, this system is widely viewed as a potential future charge-based high-speed electronic-material to complement- or replace- silicon. At the same time, the spin properties of graphene have suggested improved capability for spin-based electronics or spintronics, and spin-based quantum computing. As a result, the detection, characterization, and transport of spin have become topics of interest in graphene. Here we report a microwave photo-excited transport study of monolayer and trilayer graphene that reveals an unexpectedly strong microwave-induced electrical-response and dual microwave-induced resonances in the dc-resistance. The results suggest the resistive detection of spin resonance, and provide a measurement of the g-factor, the spin relaxation time, and the sub-lattice degeneracy-splitting at zero-magnetic-field.

description: We show that the physical subspace in the Z2-slave-spin theory is conserved under the time evolution of the system. Thus, when restricted to the physical subspace, this representation gives a complete and consistent description of the original problem. In addition, we review two known examples from the existing literature in which the projection onto the physical subspace can be relaxed: (i) the non-interacting limit in any dimension at half filling and (ii) the interacting model in the infinite dimensional limit at half filling. In both cases, physical observables are correctly obtained without explicit treatment of the constraints which define the physical subspace. In these examples, correct results are obtained, despite the fact that unphysical states enter the solution.

description: Air quality and climate change are among the biggest societal challenges that we face today.
 According to World Health Organization, air pollution is the single greatest environmental risk.
 An estimated 7 million people globally die prematurely each year due to air pollution. The
 estimated economic costs of air pollution in the Europe are well over €20 billion a year.
 Atmospheric free radicals, particularly hydroxyl (OH) and nitrate (NO3), are the drivers of
 chemical processes that determine atmospheric composition and thus influence local and
 global air quality and climate.
 Therefore, detecting and understanding the behaviour of radical species in the atmosphere is
 important. Detection of radicals is challenging because of their low mixing ratios, short lifetimes
 and fast surface losses during sampling. Current techniques for measuring radicals, which are
 based on spectroscopic and mass spectrometric methods, are technically complex,
 cumbersome and expensive. As a result, the measurement of atmospheric radicals is far from
 routine and only a few research groups worldwide can perform them in a very limited number
 of geographic locations. This presentation will provide an overview, and a discussion of the
 latest results, from the recently funded EU project ‘RADICAL’ which aims to develop small,
 low-cost sensors to electrically detect short-lived atmospheric radicals. Although challenging,
 RADICAL sensors not only have the potential to be rolled out on a global scale but can also
 be adapted to detect other important atmospheric gases. Additional Information:  Vaishali Vardhan and Subhajit Biswas presented this poster for the Royal Society of Chemistry #EnvChem 2022 conference. Adrien Gandolfo presented this poster for the iCACGP/IGAC joint International Atmospheric Chemistry Conference 2022.

description: This volume contains the proceedings of the Eighth Workshop on Model-Based Testing (MBT 2013), which was held on March 17, 2013 in Rome, Italy, as a satellite event of the European Joint Conferences on Theory and Practice of Software, ETAPS 2013. The workshop is devoted to model-based testing of both software and hardware. Model-based testing uses models describing the required behavior of the system under consideration to guide such efforts as test selection and test results evaluation. Testing validates the real system behavior against models and checks that the implementation conforms to them, but is capable also to find errors in the models themselves. The first MBT workshop was held in 2004, in Barcelona. At that time MBT already had become a hot topic, but the MBT workshop was the first event devoted mostly to this domain. Since that time the area has generated enormous scientific interest, and today there are several specialized workshops and more broad conferences on software and hardware design and quality assurance covering model based testing. MBT has become one of the most powerful system analysis tools, one of the latest cutting-edge topics related is applying MBT in security analysis and testing. MBT workshop tries to keep up with current trends.

description: Temporal networks, i.e., networks in which the interactions among a set of elementary units change over time, can be modelled in terms of time-varying graphs, which are time-ordered sequences of graphs over a set of nodes. In such graphs, the concepts of node adjacency and reachability crucially depend on the exact temporal ordering of the links. Consequently, all the concepts and metrics proposed and used for the characterisation of static complex networks have to be redefined or appropriately extended to time-varying graphs, in order to take into account the effects of time ordering on causality. In this chapter we discuss how to represent temporal networks and we review the definitions of walks, paths, connectedness and connected components valid for graphs in which the links fluctuate over time. We then focus on temporal node-node distance, and we discuss how to characterise link persistence and the temporal small-world behaviour in this class of networks. Finally, we discuss the extension of classic centrality measures, including closeness, betweenness and spectral centrality, to the case of time-varying graphs, and we review the work on temporal motifs analysis and the definition of modularity for temporal graphs.

description: This study has indicated that parasitised Biomphalaria glabrata snails maintained in a 12 Hour Light (543 Lux) and 12 Hour Dark regime, shed more Schistosoma mansoni cercariae than snails maintained in the dark. Of significance is the observation that the pattern of emergence was similar under both maintenance regimes, suggesting that momentary exposure to only 41Lux light intensity was sufficient to stimulate cercarial shedding. Results also suggested that calcium ion (Ca2+) levels of maintenance water may influence cercarial production. To enable us to compare the calcium content of individual cercariae, a protocol was developed which quantitated the fluorescent emission from the preacetabular glands of cercariae stained with Alizarin Red S, and viewed under the fluorescent microscope. The results suggested that individual cercaria had different amounts of Ca2+ in their preacetabular glands. We made the observation that cercariae lost Ca2+ from their preacetabular glands after a period of incubation at room temperature (21°C). The arbitrary units of fluorescent emission, although allowing relative comparisons between individual cercariae, do not measure total Ca2+ of the cercariae. Consequently further investigations, employing Atomic absorption and Plasma emission spectrometry, determined the total calcium content of both cercariae and shedding water. These results confirmed that aging cercariae lost Ca2+ and that the incubation water gained Ca2+ during the period. Shedding snails also lost Ca2+ during a 2 hour shedding period. To investigate whether Ca2+ levels affected surface properties of the cercariae, we incubated cercariae with EGTA, and labelled with PKH26. We found that incubation of cercariae in 20mM EGTA prevented tail loss and inhibited membrane damage. Incubating cercariae with the fluorescent PKH26 lipid label clearly highlighted the nervous system of both cercarial body and tail. The possible effect of calcium loss, by aging cercariae, on successful parasite penetration and maturation is discussed at length in the context of current knowledge.

description: We study cosmological perturbations around self-accelerating solutions to two extensions of nonlinear massive gravity: the quasi-dilaton theory and the mass-varying theory. We examine stability of the cosmological solutions, and the extent to which the vanishing of the kinetic terms for scalar and vector perturbations of self-accelerating solutions in massive gravity is generic when the theory is extended. We find that these kinetic terms are in general non-vanishing in both extensions, though there are constraints on the parameters and background evolution from demanding that they have the correct sign. In particular, the self-accelerating solutions of the quasi-dilaton theory are always unstable to scalar perturbations with wavelength shorter than the Hubble length.

description: We explore new physics scenarios which are optimally probed through precision Higgs measurements rather than direct collider searches. Such theories consist of additional electroweak charged or singlet states which couple directly to or mix with the Higgs boson; particles of this kind may be weakly constrained by direct limits due to their meager production rates and soft decay products. We present a simplified framework which characterizes the effects of these states on Higgs physics by way of tree level mixing (with neutral scalars) and loop level modifications (from electrically charged states), all expressed in terms of three mixing angles and three loop parameters, respectively. The theory parameters are constrained and in some cases even fixed by ratios of Higgs production and decay rates. Our setup is simpler than a general effective operator analysis, in that we discard parameters irrelevant to Higgs observables while retaining complex correlations among measurements that arise due to the underlying mixing and radiative effects. We show that certain correlated observations are forbidden, e.g. a depleted ratio of Higgs production from gluon fusion versus vector boson fusion together with a depleted ratio of Higgs decays to bb versus WW. Moreover, we study the strong correlation between the Higgs decay rate to gamma gamma and WW and how it can be violated in the presence of additional electrically charged particles. Our formalism maps straightforwardly onto a variety of new physics models, such as the NMSSM. We show, for example, that with a Higgsino of mass > 100 GeV and a singlet-Higgs coupling of lambda=0.7, the photon signal strength can deviate from the vector signal strength by up to ~ 40-60% while depleting the vector signal strength by only 5-15% relative to the Standard Model.

description: Metric measure spaces satisfying the reduced curvature-dimension condition $CD^*(K,N)$ and where the heat flow is linear are called $RCD^*(K,N)$-spaces. This class of non smooth spaces contains Gromov-Hausdorff limits of Riemannian manifolds with Ricci curvature bounded below by $K$ and dimension bounded above by $N$. We prove that in $RCD^*(K,N)$-spaces the following properties of the heat flow hold true: a Li-Yau type inequality, a Bakry-Qian inequality, the Harnack inequality.

description: Regardless of their close proximity, abundance measurements for both stars in α Centauri by different groups have led to varying results. We have chosen to combine the abundance ratios from five similar data sets in order to reduce systematic effects that may have caused inconsistencies. With these collated relative abundance measurements, we find that the α Cen system and the Sun were likely formed from the same material, despite the [Fe/H] enrichment observed in the α Cen binaries: 0.28 and 0.31 dex, respectively. Both α Centauri A and B exhibit relative abundance ratios that are generally solar, with the mean at 0.002 and 0.03 dex, respectively. The refractory elements (condensation temperature > 900 K) in each have a mean of -0.02 and 0.01 dex and a 1σ uncertainty of 0.09 and 0.11 dex, respectively. Given the trends seen when analyzing the refractory abundances [X/Fe] with condensation temperature, we find it possible that α Centauri A may host a yet undiscovered planet.

description: In this paper we propose a blind deconvolution method which applies to data perturbed by Poisson noise. The objective function is a generalized Kullback-Leibler divergence, depending on both the unknown object and unknown point spread function (PSF), without the addition of regularization terms; constrained minimization, with suitable convex constraints on both unknowns, is considered. The problem is nonconvex and we propose to solve it by means of an inexact alternating minimization method, whose global convergence to stationary points of the objective function has been recently proved in a general setting. The method is iterative and each iteration, also called outer iteration, consists of alternating an update of the object and the PSF by means of fixed numbers of iterations, also called inner iterations, of the scaled gradient projection (SGP) method. The use of SGP has two advantages: first, it allows to prove global convergence of the blind method; secondly, it allows the introduction of different constraints on the object and the PSF. The specific constraint on the PSF, besides non-negativity and normalization, is an upper bound derived from the so-called Strehl ratio, which is the ratio between the peak value of an aberrated versus a perfect wavefront. Therefore a typical application is the imaging of modern telescopes equipped with adaptive optics systems for partial correction of the aberrations due to atmospheric turbulence. In the paper we describe the algorithm and we recall the results leading to its convergence. Moreover we illustrate its effectiveness by means of numerical experiments whose results indicate that the method, pushed to convergence, is very promising in the reconstruction of non-dense stellar clusters. The case of more complex astronomical targets is also considered, but in this case regularization by early stopping of the outer iterations is required.

description: In dieser Arbeit geben wir ein Beispiel eines Flusses mit endlichem SRB-Maß, der den polynomialen Zerfall von Korrelationen erfüllt. Dafür nehmen wir die Konstruktion des geometrischen Lorenzflusses und fahren fort, indem wir die Natur des Sattelfixpunkts am Ursprung für einen neutralen Fixpunkt ändern. Diese Modifikation wird erreicht, indem das linearisierte Vektorfeld in einer Ursprungsumgebung für ein neutrales Vektorfeld geändert wird. Diese Änderung in der Natur des Fixpunkts wird es uns ermöglichen, eine polynomiale Flusszeit zu erhalten, was uns schließlich zum Beweis des polynomischen Zerfalls von Korrelationen für den modifizierten Fluss führen wird.
description: In this work we give an example of a flow with finite SRB-measure satisfying polynomial decay of correlations. To do that, we take the construction of the geometrical Lorenz flow and proceed by changing the nature of the saddle fixed point at the origin by a neutral fixed point. This modification is accomplished by changing the linearised vector field in a neighbourhood of origin for a neutral vector field. This change in the nature of the fixed point will allow us to obtain a polynomial flow time, which will lead us ultimately to the proof of the polynomial decay of correlations for the modified flow.

description: We present a measurement of the mean density profile of Ca II gas around galaxies out to ~ 200 kpc, traced by Fraunhofer's H & K absorption lines. The measurement is based on cross-correlating the positions of about one million foreground galaxies at z ~ 0.1 and the flux decrements induced in the spectra of about 10^5 background quasars from the Sloan Digital Sky Survey. This technique allows us to trace the total amount of Ca II absorption induced by the circumgalactic medium, including absorbers too weak to be detected in individual spectra. We can statistically measure Ca II rest equivalent widths down to several mA, corresponding to column densities of about 5x10^10 cm^{-2}. We find that the Ca II column density distribution follows N ~ rp^{-1.4} and the mean Ca II mass in the halo within 200 kpc is ~ 5x10^3 Msolar, averaged over the foreground galaxy sample with median mass ~ 10^10.3 Msolar. This is about an order-of-magnitude larger than the Ca II mass in the interstellar medium of the Milky Way, suggesting more than 90% of Ca II in the Universe is in the circum- and inter-galactic environments. Our measurements indicate that the amount of Ca II in halos is larger for galaxies with higher stellar mass and higher star formation rate. For edge-on galaxies we find Ca II to be more concentrated along the minor axis, i.e. in the polar direction. This suggests that bipolar outflows induced by star formation must have played a significant role in producing Ca II in galaxy halos.
