Tidal features in the outskirts of galaxies yield unique information about their past interactions and are a key prediction of the hierarchical structure formation paradigm. The Vera C. Rubin Observatory is poised to deliver deep observations for potentially millions of objects with visible tidal features, but the inference of galaxy interaction histories from such features is not straightforward. Utilizing automated techniques and human visual classification in conjunction with realistic mock images produced using the NewHorizon cosmological simulation, we investigate the nature, frequency, and visibility of tidal features and debris across a range of environments and stellar masses. In our simulated sample, around 80 per cent of the flux in the tidal features around Milky Way or greater mass galaxies is detected at the 10-yr depth of the Legacy Survey of Space and Time (30-31 mag arcsec-2), falling to 60 per cent assuming a shallower final depth of 29.5 mag arcsec-2. The fraction of total flux found in tidal features increases towards higher masses, rising to 10 per cent for the most massive objects in our sample (M* ∼1011.5 M⊙). When observed at sufficient depth, such objects frequently exhibit many distinct tidal features with complex shapes. The interpretation and characterization of such features varies significantly with image depth and object orientation, introducing significant biases in their classification. Assuming the data reduction pipeline is properly optimized, we expect the Rubin Observatory to be capable of recovering much of the flux found in the outskirts of Milky Way mass galaxies, even at intermediate redshifts (z < 0.2). © 2022 The Author(s) Published by Oxford University Press on behalf of Royal Astronomical Society.

The Implicit Path Enumeration Technique (IPET) has become widely accepted as a powerful technique to compute upper bounds on the Worst-Case Execution Time (WCET) of time-critical software components. While the technique works fine whenever fixed execution times can be assumed for the atomic program parts, standard IPET does not consider the context-dependence of execution times. As a result, the obtained WCET bounds can often be overly pessimistic. The issue of context-dependence has previously been addressed in the field of static timing analysis, where context-dependent execution times of program parts can be extracted from a hardware model. In the case of measurement-based execution time analysis, however, contexts must be derived from timed execution traces. In the present extended abstract we present an overview of our work on the automatic detection and exploitation of context dependencies from timed execution traces. © 2010 Springer-Verlag.

Eric Gordon (2009) writes of “network locality – the experience of interacting with located data within the perceived infinity of global access” (p. 22). The smartphone, alongside the rise of digital mapping systems such as Google Maps and Open Street Maps, has seen the increasing need for people to locate their activities. Photographs can be geo-located, capturing places frozen in time, and we can now log-in to virtual equivalents of shops, work buildings, or our own homes with applications such as FourSquare and Gowalla. Each of these instances is only possible through an underlying network of global connections. However, in doing so, they are also changing the mapped narrative of local areas. The map is more than a means of seeking directions, but allows for a visualisation of data in various formats. This paper will focus on mapped data collected from areas local to the GPS co-ordinates of each data collection. FourSquare places, ephemeral geo-located tweets and geotagged photographs will be visualised against a background of a local map. Each area will be defined in terms of a community or town, and will be viewed as an isolated snapshot, depicted as a miniature mapped landscape in amongst the surrounding area. The project seeks to understand the changing landscape of each local area by analysing what John Pickles (2004) defines as "socio-spatial identities" that he sees to be the basis of many contemporary maps as "digital mapping has begun to influence many more domains of social life" (p. 10). Whereas most location-based applications seek to define the user’s position in amongst a global network, this project examines the changing narratives of the local area through numerous check-ins, tweets and images. The changing nature of the map is captured at different points in time as a way of analysing the ephemeral landscape of data depicting the opinions, locations and imagery left as digital memories or tokens by those within the area. The narrative of place takes precedence over the identity of the user as places and spaces are re-examined in light of this user-generated content.

This paper explores the relationship between improvisation and divergent thinking in the context of schema theory, where it is suggested that improvisation encourages people to break away from set patterns of thinking. Improvisation is the act of creating something new on the spur of the moment. Verbal improvisation is the act of spontaneously creating strings of new words, while avoiding pre-planned phrases (Sawyer, 2008). Divergent thinking was assessed using the Alternative Uses Task (AUT) before and after a treatment condition of either improvisation or control tasks. Experiment One examined verbal improvisation, while controlling for mood, and observed an increase in divergent thinking scores in terms of fluency, originality and flexibility following improvisation but not a control task. No effects of mood were found. Experiment Two examined music improvisation and also observed an increase in divergent thinking for fluency, originalityand flexibility following improvisation but not following a control condition (p<.05 in all cases). The results show that participating in verbal and music improvisation increases scores on a divergent thinking task, suggesting that improvisation may enable people to break away from set patterns of thinking as influenced by schemas (Sawyer, 2001).

This text explores the culture and literature of nineteenth-century America, examining several genres including the early American novel, realist fiction and historical romance, short stories and poetry. It goes on to highlight core debates such as the American landscape, global identity, women’s writing and the city. This is all read in the context of the revolution, independence, civil war and consolidation. Some of the primary texts discussed are: The White Heron, The Adventures of Huckleberry Finn, The Scarlet Letter, Leaves of Graves, and particular slave narratives. This series provides detailed commentaries and steers the student through key theories and discussions. By linking literature with its historical and scholarly contexts, this book is invaluable for any study of nineteenth-century American literature.

This study investigated the impact that mouth rinsing carbohydrate solution has on skill-specific performance and reaction time following a fatigue inducing bout of fencing in epee fencers. Nine healthy, national level epee fencers visited a laboratory on 2 occasions, separated by a minimum of 5 days, to complete a 1-minute lunge test and Stroop test pre and post fatigue. Heart rate and ratings of perceived exertion (RPE) were recorded during completion of the fatiguing protocol. Between fights the participants mouth rinsed for 10 seconds, either 25ml of 6.7% maltodextrin solution (MALT) or water (PLAC). Blood lactate and glucose were recorded at baseline, pre- and post-testing. Results showed an increase in heart rate and overall RPE over time in both conditions. There were no differences in blood glucose (F(1,8)=.63, P=.4, ηp=.07) or blood lactate levels (F(1,8)=.12, P=.70, ηp=.01) between conditions as a function of time. There was a significant improvement in lunge test accuracy during the MALT trial (F(1,8)=5.21, P=.05, ηp=.40) with an increase from pre (81.2 ±8.3%) to post (87.6 ±9.4%), whereas there was no significant change during the placebo (pre 82.1 ±8.8%, post 78.8 ±6.4%). There were no recorded differences between conditions in response time to congruent (F(1,8)=.33, P=.58, ηp=.04) or incongruent stimuli (F(1,8)=.19, P=.68, ηp=.02). The study indicates that when fatigued mouth rinsing MALT significantly improves accuracy of skill-specific fencing performance but no corresponding influence on reaction time was observed.

The cores of clusters at 0 ≲ z ≲ 1 are dominated by quiescent early-type galaxies, whereas the field is dominated by star-forming late-type galaxies. Clusters grow through the accretion of galaxies and groups from the surrounding field, which implies that galaxy properties, notably the star formation ability, are altered as they fall into overdense regions. The critical issues for understanding this evolution are how the truncation of star formation is connected to the morphological transformation and what physical mechanism is responsible for these changes. The GaLAxy Cluster Evolution Survey (GLACE) is conducting a thorough study of the variations in galaxy properties (star formation, AGN activity, and morphology) as a function of environment in a representative and well-studied sample of clusters. To address these questions, the GLACE survey is making a deep panoramic survey of emission line galaxies (ELG), mapping a set of optical lines ([O II], [O III], Hβ andHα/[N II] when possible) in several galaxy clusters at z ~ 0.40, 0.63, and 0.86. Using the tunable filters (TF) of the OSIRIS instrument at the 10.4 m GTC telescope, the GLACE survey applies the technique of TF tomography: for each line, a set of images are taken through the OSIRIS TF, each image tuned at a different wavelength (equally spaced), to cover a rest frame velocity range of several thousand km s-1 centred on the mean cluster redshift, and scanned for the full TF field of view of an 8 arcmin diameter. Here we present the first results of the GLACE project, targeting the Hα/[N II] lines in the intermediate-redshift cluster ZwCl 0024.0+1652 at z = 0.395. Two pointings have been performed that cover ~2 × rvir. We discuss the specific techniques devised to process the TF tomography observations in order to generate the catalogue of cluster Hα emitters, which contains more than 200 sources down to a star formation rate (SFR) ≲1 M⊙/yr. An ancillary broadband catalogue is constructed, allowing us to discriminate line interlopers by means of colour diagnostics. The final catalogue contains 174 unique cluster sources. The AGN population is distinguished using different diagnostics and found to be ~37% of the ELG population. The median SFR of the star-forming population is 1.4 M⊙/yr. We studied the spatial distribution of ELG and confirm the existence of two components in the redshift space. Finally, we exploited the outstanding spectral resolution of the TF, attempting to estimate the cluster mass from ELG dynamics, finding M200 = (4.1 ± 0.2) × 1014 M⊙ h-1, in agreement with previous weak-lensing estimates.
