description: The two-dimensional two-orbital Hubbard model is studied with the use of finite-size cluster worldline quantum Monte Carlo algorithm. This model is widely used for simulation of the band structure of FeAs clusters, which are structure elements of Fe-based high-temperature superconductors. The choice of a special basis set of hyper-sites allowed to take into account four-fermion operator terms and to overcome partly the sign problem. Spectral functions and the density of states for various parameters of the model are obtained in the undoped and low-doped regimes. The correlated distortion of the spectral density with the change of doping is observed, and the applicability of the "hard-band" approximation in the doped regime is demonstrated. Profiles of the momentum distribution are obtained for the first Brillouin zone; they have pronounced jump near the Fermi level, which decreases with the growth of the strength of the interaction. The invariance of the Fermi surface with respect to the strength of the interaction is testified. Nesting is found in the case of electron and hole doping. Fermi-liquid parameters of the model are derived. Z-factor grows sharply with the increasing the level of doping, and monotonously decreases with the growth of the strength of the interaction. Moreover, electron-hole doping asymmetry of the Z-factor is revealed. The non-Fermi liquid behaviour and the deviation from Luttinger theorem are observed.

description: The study was conducted to evaluate the effect of graded level of sundried cassava peel meal (CPM) blended with palm oil sludge (POS) on organoleptic qualities, carcass and internal organ characteristics of broiler chickens. A total of 150day old broiler chicks from Caskada Company were used for the study. The birds were fed graded levels of sundried cassava peel meal plus palm oil sludge (CPMPOS) (0, 2.5, 5.0, 7.5,10.0 kg) in partial replacement of maize for treatment 1 2, 3, 4 and 5 respectively. On day 56 of the experiment, two birds from each replicate was selected and starved for at least 12 hours, six birds per treatment that were closest to the mean were selected from each of the treatment, tagged and slaughtered then scalded in hot water of 55oC for one minute and dressed to evaluate carcass characteristics, processed and boiled for organoleptic properties. Thirty panelists were chosen for the organoleptic test. Data were collected based on the information generated from the nine (9) point hedonic scale. The panelists evaluated the samples for colour, flavour, juciness, tenderness and general acceptability. The result showed that there is significant difference (P< 0.05) for tenderness and juiceness and no significant effect (P> 0.05) on the appearance, colour, overall acceptability and flavour. The results showed that there was significant difference (P < 0.05) in live weight, shank, wing, drumstick, head and abdominal fat. There were no significant effect (P > 0.05) in the values of the intestine, gall bladder and heart. Thus, CPMPOS can partially replace maize on broiler diets without any deleterious effect on the organoleptic, carcass and internal organs quality.

description: We study parton distributions for two partons, a quark and a gluon, in the light-front dressed quark model, with focus on correlations between the two partons. The model calculation leads to sizable spin-spin and spin-kinematic correlations of interest for studies of double parton scattering (DPS) in high-energy collisions. In particular, we find that the transverse dependence of the double parton distributions (DPDs) does not factorize within the model. The results gives insight to the strengths of correlations in different kinematical regions, which can help in constructing input DPDs in cross section calculations.

description: Decomposing an arbitrary electron energy distribution into sums of Maxwellian and power law components is an efficient method to calculate synchrotron emission and absorption. We use this method to study the effect of non-thermal electrons on submm images and spectra of the Galactic center black hole, Sgr A*. We assume a spatially uniform functional form for the electron distribution function and use a semi-analytic radiatively inefficient accretion flow and a 2D general relativistic MHD snapshot as example models of the underlying accretion flow structure. We develop simple analytic models which allow us to generalize from the numerical examples. A high energy electron component containing a small fraction (few per cent) of the total internal energy (e.g. a "power law tail") can produce a diffuse halo of emission, which modifies the observed image size and structure. A population of hot electrons with a larger energy fraction (e.g. resulting from a diffusion in electron energy space) can dominate the emission, so that the observed images and spectra are well approximated by considering only a single thermal component for a suitable choice of the electron temperature. We discuss the implications of these results for estimating accretion flow or black hole parameters from images and spectra, and for the identification of the black hole "shadow" in future mm-VLBI data. In particular, the location of the first minimum in visibility profiles does not necessarily correspond to the shadow size as sometimes assumed.

description: Water can exist in a metastable liquid state under tension for long times before the system relaxes into the vapor via cavitation, i.e., bubble nucleation. Microscopic information on the cavitation process can be extracted from experimental data by use of the nucleation theorem, which relates measured cavitation rates to the size of the critical bubble. To apply the nucleation theorem to experiments performed along an isochoric path, for instance, in cavitation experiments in mineral inclusions, knowledge of the bubble entropy is required. Using computer simulations, we compute the entropy of bubbles in water as a function of their volume over a wide range of tensions from free energy calculations. We find that the bubble entropy is an important contribution to the free energy which significantly lowers the barrier to bubble nucleation, thereby facilitating cavitation. Furthermore, the bubble entropy per surface area depends on the curvature of the liquid--vapor interface, decreasing approximately linearly with its mean curvature over the studied range of bubble volumes. At room temperature, the entropy of a flat liquid--vapor interface at ambient pressure is very similar to that of critical bubbles over a wide range of tensions, which justifies the use of the former as an approximation when interpreting data from experiments. Based on our simulation results, we obtain an estimate for the volume of the critical bubble from experimentally measured cavitation rates.

In 2015, an update on the fitting techniques for the Dihadron Fragmentation Functions has led to an improved extraction of the transversity PDF and, as a consequence, the nucleon tensor charge. We discuss the impact of the determination of the latter on search for physics Beyond the Standard Model, focusing on the error treatment. We also comment on the future of the extraction of the subleading-twist PDF $e(x)$ from JLab soon-to-be-released Beam Spin Asymmetry data.

description: We study the evolution of holographic screens, both generally and in explicit examples, including cosmology and gravitational collapse. A screen $H$ consists of a one-parameter sequence of maximal surfaces called leaves. Its causal structure is nonrelativistic. Each leaf can store all of the quantum information on a corresponding null slice holographically, at no more than one bit per Planck area. Therefore, we expect the screen geometry to reflect certain coarse-grained quantities in the quantum gravity theory. In a given spacetime, there are many different screens, which are naturally associated to different observers. We find that this ambiguity corresponds precisely to the free choice of a single function on $H$. We also consider the background-free construction of $H$, where the spacetime is not given. The evolution equations then constrain aspects of the full spacetime and the screen's embedding in it.

description: Diffusion is one of the key processes that allows material to move around, it is a controlling factor both of planetary formation and of deformation. This study focuses on self - diffusion of fcc phase iron . Here a laser heated diamond anvil cells were used to generate the high pressures and temperatures, simulating mantle conditions. Iron self - diffusion was measured at 43.6 GPa at both 2100 K and 2000 K, giving diffusion coefficient measurements of 1.46x10 - 14 m 2 /s - 1 at 2100 K and 9.92x10 - 14 m 2 /s - 1 at 2000 K. These diffusion coefficients were then plotted along with existing data at lower pressures against three different diffusion models, to see whether the models include reasonable assumptions and are accurate at predicting the diffusion of iron at high temperatures. All three of the models consistently underestimated the diffusion coefficient at higher pressures by at least two orders of magnitude . One of the models was recalculated using new values for activation volume (1.43 cm 3 /mol) and activation energy (431 kJ/mol), the model now reliably predicts the diffusion coefficient of iron at high pressures.

description: The Disk Detective citizen science project aims to find new stars with 22 micron excess emission from circumstellar dust using data from NASA's WISE mission. Initial cuts on the AllWISE catalog provide an input catalog of 277,686 sources. Volunteers then view images of each source online in 10 different bands to identify false-positives (galaxies, background stars, interstellar matter, image artifacts, etc.). Sources that survive this online vetting are followed up with spectroscopy on the FLWO Tillinghast telescope. This approach should allow us to unleash the full potential of WISE for finding new debris disks and protoplanetary disks. We announce a first list of 37 new disk candidates discovered by the project, and we describe our vetting and follow-up process. One of these systems appears to contain the first debris disk discovered around a star with a white dwarf companion: HD 74389. We also report four newly discovered classical Be stars (HD 6612, HD 7406, HD 164137, and HD 218546) and a new detection of 22 micron excess around a previously known debris disk host star, HD 22128.

description: This study aimed to assess how physicochemical factors affected the efficiency of the process for producing biodiesel from oily residues in fishing industry effluent. The oil extracted from the grease traps was initially characterized for the stabilization of the process' influential parameters, obtaining viscosities of 38 mPa/s, densities of 0.93 g/ml, and saponification indices of 260.40 mg KOH/g; it was then necessary to neutralize the oil and dry it to reduce the oil's acidity to 0.97% and its humidity to 0.03%, in order to meet the conditions for subsequent transesterification, This led to the conclusion that T7 (80 ºC, 9:1, and 0.8%) was the best treatment. It produced a 94% performance of biodiesel extraction and had the following properties: acidity of 0.39 mg KOH/g, viscosity of 2.7 mPa/s, ashes of less than 0.02%, density of 883.7 kg/m3, flash point of 120 ºC, and cetane index of 41. However, it had a high-water content.

description: Given a vector field on a manifold M, we define a globally conserved quantity to be a differential form whose Lie derivative is exact. Integrals of conserved quantities over suitable submanifolds are constant under time evolution, the Kelvin circulation theorem being a well-known special case. More generally, conserved quantities are well-behaved under transgression to spaces of maps into M. We focus on the case of multisymplectic manifolds and Hamiltonian vector fields. We show that in the presence of a Lie group of symmetries admitting a homotopy co-momentum map, one obtains a whole family of globally conserved quantities. This extends a classical result in symplectic geometry. We carry this out in a general setting, considering several variants of the notion of globally conserved quantity.

description: In present paper, we investigate the multifractality signatures in hourly time series extracted from CoRoT spacecraft database. Our analysis is intended to highlight the possibility that astrophysical time series can be members of a particular class of complex and dynamic processes which require several photometric variability diagnostics to characterize their structural and topological properties. To achieve this goal, we search for contributions due to nonlinear temporal correlation and effects caused by heavier tails than the Gaussian distribution, using a detrending moving average algorithm for one-dimensional multifractal signals (MFDMA). We observe that the correlation structure is the main source of multifractality, while heavy-tailed distribution plays a minor role in generating the multifractal effects. Our work also reveals that rotation period of stars is inherently scaled by degree of multifractality. As a result, analyzing the multifractal degree of referred series, we uncover an evolution of multifractality from shorter to larger periods.

description: We study the faces of the set of quantum correlations, i.e., the Bell and noncontextuality inequalities without any quantum violation. First, we investigate the question whether every proper (tight) Bell inequality for two parties, other than the trivial ones from positivity, normalization and no-signaling can be violated by quantum correlations, i.e., whether the classical Bell polytope or the smaller correlation polytope share any facets with their respective quantum sets. To do this, we develop a recently derived bound on the quantum value of linear games based on the norms of game matrices to give a simple sufficient condition to identify linear games with no quantum advantage. Additionally we show how this bound can be extended to the general class of unique games, illustrating it for the case of three outcomes. We then show as a main result that the paradigmatic examples of correlation Bell inequalities with no quantum violation, namely the non-local computation games do not constitute tight Bell inequalities, not even for the correlation polytope. We also extend this to an arbitrary prime number of outcomes for a specific class of these games. We then study the faces in the simplest CHSH Bell scenario of binary dichotomic measurements, and identify edges in the set of quantum correlations in this scenario. Finally, we relate the non-contextual polytope of single-party correlation inequalities with the cut polytope $CUT(\nabla G)$, where $G$ denotes the compatibility graph of observables in the contextuality scenario and $\nabla G$ denotes the suspension graph of $G$. We observe that there exist tight non-contextuality inequalities with no quantum violation, and furthermore that this set of inequalities is beyond those implied by the Consistent Exclusivity principle.

description: Reconstructing 3D scenes from multiple views has made impressive strides in recent years, chiefly by correlating isolated feature points, intensity patterns, or curvilinear structures. In the general setting - without controlled acquisition, abundant texture, curves and surfaces following specific models or limiting scene complexity - most methods produce unorganized point clouds, meshes, or voxel representations, with some exceptions producing unorganized clouds of 3D curve fragments. Ideally, many applications require structured representations of curves, surfaces and their spatial relationships. This paper presents a step in this direction by formulating an approach that combines 2D image curves into a collection of 3D curves, with topological connectivity between them represented as a 3D graph. This results in a 3D drawing, which is complementary to surface representations in the same sense as a 3D scaffold complements a tent taut over it. We evaluate our results against truth on synthetic and real datasets.

description: Domain generalization (DG) is a branch of transfer learning that aims to train the learning models on several seen domains and subsequently apply these pre-trained models to other unseen (unknown but related) domains. To deal with challenging settings in DG where both data and label of the unseen domain are not available at training time, the most common approach is to design the classifiers based on the domain-invariant representation features, i.e., the latent representations that are unchanged and transferable between domains. Contrary to popular belief, we show that designing classifiers based on invariant representation features alone is necessary but insufficient in DG. Our analysis indicates the necessity of imposing a constraint on the reconstruction loss induced by representation functions to preserve most of the relevant information about the label in the latent space. More importantly, we point out the trade-off between minimizing the reconstruction loss and achieving domain alignment in DG. Our theoretical results motivate a new DG framework that jointly optimizes the reconstruction loss and the domain discrepancy. Both theoretical and numerical results are provided to justify our approach.

description: We present infrared views of the environmental effects on the dust properties in star-forming (SF) galaxies at z ~ 0, using the AKARI Far-Infrared Surveyor (FIS) all-sky map and the large spectroscopic galaxy sample from Sloan Digital Sky Survey (SDSS) Data Release 7 (DR7). We restrict the sample to those within the redshift range of 0.05 < z < 0.07 and the stellar mass range of 9.2 < log_10 (M_star/M_solar). We select SF galaxies based on their H_alpha equivalent width (EW_Ha> 4 A) and emission line flux ratios. We perform far-infrared (FIR) stacking analyses by splitting the SDSS SF galaxy sample according to their stellar mass, specific SFR (SSFR_SDSS), and environment. We derive total infrared luminosity (LIR) for each subsample using the average flux densities at WIDE-S (90 micron) and WIDE-L (140 micron) bands, and then compute IR-based SFR (SFR_IR) from L_IR. We find a mild decrease of IR- based SSFR (SSFR_IR) amongst SF galaxies with increasing local density (~0.1-dex level at maximum), which suggests that environmental effects do not instantly shut down the SF activity in galaxies. We also derive average dust temperature (T_dust) using the flux densities at 90 micron and 140 micron bands. We confirm a strong positive correlation between T_dust and SSFR_IR, consistent with recent studies. The most important finding of this study is that we find a marginal trend that T_dust increases with increasing environmental galaxy density. Although the environmental trend is much milder than the SSFR-T_dust correlation, our results suggest that the environmental density may affect the dust temperature in SF galaxies, and that the physical mechanism which is responsible for this phenomenon is not necessarily specific to cluster environments because the environmental dependence of T_dust holds down to relatively low-density environments.

description: Wireless networks are commonly used in public spaces, universities and public institutions and provide accurate and easily accessible information to monitor the mobility and behavior of users. Following the application of containment measures during the recent pandemic, we analyse extensive data from the WiFi network in a University Campus in Italy during three periods, corresponding to partial lockdown, partial opening, and almost complete opening. We measure the probability distributions of groups and link activation at Wi-Fi Access Points, investigating how different areas are used in the presence of restrictions. We rank the hotspots and the area they cover according to their crowding and to the probability of link formation, which is the relevant variable in determining potential outbreaks. We consider a recently proposed epidemic model on simplicial temporal networks and we use the measured distributions to infer the change in the reproduction number in the three phases. Our data show that additional measures are necessary to limit the epidemic spreading in the total opening phase, due to the dramatic increase in the number of contacts.

description: We propose a model of discrete time dynamic congestion games with atomic players and a single source-destination pair. The latencies of edges are composed by free-flow transit times and possible queuing time due to capacity constraints. We give a precise description of the dynamics induced by the individual strategies of players and of the corresponding costs, either when the traffic is controlled by a planner, or when players act selfishly. In parallel networks, optimal and equilibrium behavior eventually coincides, but the selfish behavior of the first players has consequences that cannot be undone and are paid by all future generations. In more general topologies, our main contributions are three-fold. First, we show that equilibria are usually not unique. In particular, we prove that there exists a sequence of networks such that the price of anarchy is equal to $n-1$, where $n$ is the number of vertices, and the price of stability is equal to 1. Second, we illustrate a new dynamic version of Braess's paradox: the presence of initial queues in a network may decrease the long-run costs in equilibrium. This paradox may arise even in networks for which no Braess's paradox was previously known. Third, we propose an extension to model seasonalities by assuming that departure flows fluctuate periodically over time. We introduce a measure that captures the queues induced by periodicity of inflows. This measure is the increase in costs compared to uniform departures for optimal and equilibrium flows in parallel networks.

description: Popular literature and guidebooks on minimalism and decluttering have brought the idea of “less is more” into the mainstream. Although decluttering constitutes a central household chore in consumer societies, it is rarely communicated as work within the current popular minimalism discourse, but rather as an expression of self-care. Whether and to what extent this “lifestyle minimalism” can contribute to sustainable consumption has – with a few exceptions – not yet been studied in detail. In this article, decluttering is first conceptualized in between housework and self-care. Based on this work, potentials and limits for the promotion of sustainable consumption are outlined. Finally, initial insights from an ongoing citizen science project on decluttering in Germany are presented. The qualitative results from two workshops and two reflection exercises show that the main motivation for participants is the dissatisfaction with their multitude of possessions and the desire for fewer material possessions in the future. The decision to declutter can be understood as a window of opportunity in which individuals are willing to reflect on and realign their possessions and desires for goods. Thus, we argue that decluttering can be a relevant starting point for changing consumption behavior toward (more) sustainable consumption. At the same time, it remains unclear whether and to what extent the participants' willingness to change regarding possessions and consumption actually leads to more sustainable consumption behavior after decluttering. It is even conceivable that the newly gained space will stimulate additional consumption. Decluttering would then rather function as a catalyst for further consumption (and would have no or rather a negative contribution to sustainability goals). Further research is needed to shed light on this.

description: Across scales, many biological phenomena, such as protein folding or bioadhesion and cohesion, rely on synergistic effects of different amino acid side chains at multiple positions in the protein sequence. These are often fine-tuned by post-translational modifications that introduce additional chemical properties. Several PTMs can now be genetically encoded and precisely installed at single and multiple sites by genetic code expansion. Protein nitration is a PTM of particular interest because it has been associated with several diseases. However, even when these nitro groups are directly incorporated into proteins, they are often physiologically reduced during or shortly after protein production. We have solved this problem by using an engineered Escherichia coli host strain. Six genes that are associated with nitroreductase activity were removed from the genome in a simple and robust manner. The result is a bacterial expression host that can stably produce proteins and peptides containing nitro groups, especially when these are amenable to modification. To demonstrate the applicability of this strain, we used this host for several applications. One of these was the multisite incorporation of a photocaged 3,4-dihydroxyphenylalanine derivative into Elastin-Like Polypeptides. For this non-canonical amino acid and several other photocaged ncAAs, the nitro group is critical for photocleavability. Accordingly, our approach also enhances the production of biomolecules containing photocaged tyrosine in the form of ortho-nitrobenzyl-tyrosine. We envision our engineered host as an efficient tool for the production of custom designed proteins, peptides or biomaterials for various applications ranging from research in cell biology to large-scale production in biotechnology.
Nomads of the Word: Reading the Book of Acts from a Semitic Perspective

description: Modern biblical criticism has insisted on the historical character of the Book of Acts. Luke has been crowned as the First Historian of the Church, with all the connotations that such a title implies, and scholars have shown special interest in the influence of different philosophical streams such as Pythagoreanism, Epicureanism and Aristotelian Rhetoric (Dibelius, Haenchen, Conzelmann). The school of narrative criticism has proposed new perspectives of interpretation based on the reader's response theories (Marguerat).
 This article proposes a narrative reading based on Father Tarazi's understanding of Biblical Mashal as an “edifying story” and his approach to the figure of the Shepherd in Biblical literature. Some selected texts from Acts will be interpreted in order to show how the Apostles adopted and put into practice this Old Testament model, offering an alternative to the hegemony and oppression of worldly power represented in this case by the Roman Empire. The images of a wandering Aramean, a shepherd of sheep, and a wandering preacher propose a model of life that will form the identity of those who believed in Jesus Christ as Lord and Savior.

description: IN UNIFIED RELATIVISTIC QUANTUM GRAVITY THEORY:

Dark energy arises naturally from the mass and distribution of gravitons, offering a quantum explanation for cosmic acceleration.

Planck’s constant, Newton’s gravitational constant, and the cosmological constant emerge naturally from graviton dynamics.

Gravity is modified at both short and long ranges through Yukawa-type corrections, predicting measurable deviations from Newtonian laws — providing new explanations for galactic rotation curves, cosmic structure formation, and lensing effects without requiring dark matter.

Black holes are redefined: their temperature, luminosity, entropy, and lifetime derive directly from the quantum structure of spacetime, governed by graviton properties.

The holographic principle emerges as a natural property of graviton dynamics: the information content of a region of space scales not with its volume, but with its surface area.

The time-dependent Schrödinger equation is recovered as a limiting case of gravitational quantum evolution, connecting ordinary quantum mechanics to the dynamics of spacetime itself.

A modified Heisenberg uncertainty principle introduces a fundamental minimum length, reshaping quantum behavior at the Planck scale.

The Wheeler–DeWitt equation, often called the "wavefunction of the universe," finds its foundation in URQG’s framework, linking the geometry of the universe to its quantum state without external assumptions.

description: A new method capable of capturing coherent electric field structures propagating at nearly the speed of light in plasma with a time resolution as small as a few femtoseconds is proposed. This method uses a few femtoseconds long relativistic electron bunch to probe the wake produced in a plasma by an intense laser pulse or an ultra-short relativistic charged particle beam. As the probe bunch traverses the wake, its momentum is modulated by the electric field of the wake, leading to a density variation of the probe after free-space propagation. This variation of probe density produces a snapshot of the wake that can directly give many useful information of the wake structure and its evolution. Furthermore, this snapshot allows detailed mapping of the longitudinal and transverse components of the wakefield. We develop a theoretical model for field reconstruction and verify it using 3-dimensional particle-in-cell (PIC) simulations. This model can accurately reconstruct the wakefield structure in the linear regime, and it can also qualitatively map the major features of nonlinear wakes. The capturing of the injection in a nonlinear wake is demonstrated through 3D PIC simulations as an example of the applications of this new method.

Human-centred design and person-centred care: developing design personas in residential aged care

description: Background: Personas are a human-centred design technique that employ a narrative style to present data and insights in a form that engages our social conscience, emotional intuition and empathy. Representing clusters of service users who display similar behaviours, attitudes or needs, personas can help shift our focus away from the needs of the organisation or system and onto the needs of the service user. Method: First, the concept of personas and human - centred design in aged care was explored through a literature review and examination of persona methodology. Next , the persona methodology was implemented in a residential aged care facility in Sydney, Australia . Data was collected through observation and interview s to understand resident s ' needs, behaviours and attitudes . A variable mapping process was used to identify clusters of similar residents. Insights were presented in the form of personas which were reviewed with key staff to obtain feedback on their usefulness for informing future service improvement initiative. Results The literature review revealed few studies using human - centred participato ry design techniques to enhance person - centred care in aged care . One human - centred design technique not previously utilised in aged care was personas . A methodology to develop ethnographic research - based personas in a residential aged care setting was developed . Four key behavioural and attitudinal variables were identified that distinguished between residents: tendency to interact/isolate; likes to help out/does not help out (insular); strong/weak family bond; and, feeling unsettled in care. These four factors were manifest in three personas. Each persona has a unique identity but draws on the anecdotes, life stories an d experiences of all residents involved in the study. Conclusions: This proof of concept study has demonstrated the potential of personas to assist in the design and delivery of more person - centred care : to drive person - centred decision making ; turn resident data into a ctionable insights; and, encourage aged - care facilities to look at how to deliver person - centred care more effective ly and in new ways. For residents, the technique could allow a vulnerable, often marginalised, group to express their experience, needs, and expectations in their own voice. For service delivery, personas could be used to great advantage in residential aged care to overcome the challenge of operationalising person - centred care.

description: We present the discovery of stellar tidal tails around the Large and the Small Magellanic Clouds in the Gaia DR1 data. In between the Clouds, their tidal arms are stretched towards each other to form an almost continuous stellar bridge. Our analysis relies on the exquisite quality of the Gaia's photometric catalogue to build detailed star-count maps of the Clouds. We demonstrate that the Gaia DR1 data can be used to detect variable stars across the whole sky, and in particular, RR Lyrae stars in and around the LMC and the SMC. Additionally, we use a combination of Gaia and Gale to follow the distribution of Young Main Sequence stars in the Magellanic System. Viewed by Gaia, the Clouds show unmistakable signs of interaction. Around the LMC, clumps of RR Lyrae are observable as far as ~20 degrees, in agreement with the most recent map of Mira-like stars reported in Deason et al (2016). The SMC's outer stellar density contours show a characteristic S-shape, symptomatic of the on-set of tidal stripping. Beyond several degrees from the center of the dwarf, the Gaia RR Lyrae stars trace the Cloud's trailing arm, extending towards the LMC. This stellar tidal tail mapped with RR Lyrae is not aligned with the gaseous Magellanic Bridge, and is shifted by some ~5 degrees from the Young Main Sequence bridge. We use the offset between the bridges to put constraints on the density of the hot gaseous corona of the Milky Way.
