Dark Matter as Dense Color Superconductor

We discuss a novel cold dark matter candidate which is formed from the ordinary quarks during the QCD phase transition when the axion domain wall undergoes an unchecked collapse due to the tension in the wall. If a large number of quarks is trapped inside the bulk of a closed axion domain wall, the collapse stops due to the internal Fermi pressure. In this case the system in the bulk, may reach the critical density when it undergoes a phase transition to a color superconducting phase with the ground state being the quark condensate, similar to BCS theory. If this happens, the new state of matter representing the diquark condensate with a large baryon number B > 10^{20} becomes a stable soliton-like configuration. Consequently, it may serve as a novel cold dark matter candidate.Comment: To appear in the Proceedings "Dark Matter 2002

From an interview with the artists (Jerwood Visual Arts 2012) Our blog - kimcolemanjennyhogarth.co.uk - is an on-going archive of short videos made separately to be shown together. Creating a blog has been a way for our recorded videos to function more like our works that use live video feeds, where the content is potentially endless. We’re interested in how the content of a video is edited and compiled. We often create parameters when making a video and whatever happens within these limits becomes the footage. With this work for Assembly – where we have been making videos as we move around – we started letting the movement of the camera when travelling in a train, a car, on escalators, walking, or whatever, determine the content and length. For previous works using CCTV footage, we let the cameras’ automatic pre-set positions select the content of the installation, and we have made videos where we expose the camera to changing light conditions, demonstrating the limits of the camera’s automatic light aperture and focus. The content of the videos reflect the medium we’re using and our experience of creating the work. We post to the blog alternately. As the videos have accumulated they have mirrored each other at points. Symmetry and repetition in the videos themselves reflect this conversational dynamic, picking up on an idea in an earlier conversation or responding to a previous video in the sequence. Our works also capitalise on video’s inherent relationship to light and its intrinsic link to how we see, how cameras work and to the fundamentals of representation and perception. They draw out links between video and performance, especially how objects can seem to perform through interaction with a lens, and how people perform consciously and unconsciously in relation to a camera. We’re interested in how the camera is a prop in the performance of making the video. What our cameras record is changed by the events it is exposed to, and the subject is also altered by the presence of a camera. kimcolemanjennyhogarth.co.uk has been shown as part of ASSEMBLY, a Jerwood Encounters exhibition of newly commissioned work by artists who work collaboratively and are influenced by the current digital landscape. The website provides a space for further conversation and includes images, videos and links from exhibiting artists Kim Coleman & Jenny Hogarth, The Hut Project, Charlie Woolley, curator Sarah Williams, with conversations conducted by James Smith, Editor of thisistomorrow.info. kimcolemanjennyhogarth.co.uk was also enabled by a LUX/Leverhulme Trust travel and exhibition fund. The work was shown as part of Detroit, an exhibition of works create by LUX Associate Artists. The exhibition also featured work by Lucy Clout, Cara Tolmie, Paul Abbot, Erik Blinderman, Mark Barker and Maria Tanaguch

Finite size effects on the Poynting-Robertson effect: a fully general relativistic treatment

Ever since the first discovery of Poynting and Robertson, the radiation source has been treated as merely a point. Even in a very few studies where the size of the source has been taken into account, the treatment of the problem remained largely non-relativistic. In the present work, we address the issue of the finite size effects on the Poynting-Robertson effect in a fully relativistic manner for the first time. As a result, the emergence and the characteristic of the critical point/suspension orbit can be studied in a systematic and detailed manner.Comment: 11pages, 3figure

The O(N) Nonlinear Sigma Model in the Functional Schr\"{o}dinger Picture

We present a functional Schr\"{o}dinger picture formalism of the (1+1)-dimensional $O(N)$ nonlinear sigma model. The energy density has been calculated to two-loop order using the wave functional of a gaussian form, and from which the nonperturbative mass gap of the boson fields has been obtained. The functional Schr\"{o}dinger picture approach combined with the variational technique is shownto describe the characteristics of the ground state of the nonlinear sigma model in a transparent way.Comment: 13 pages, no figures, Latex fil

Modeling river delta formation

A new model to simulate the time evolution of river delta formation process is presented. It is based on the continuity equation for water and sediment flow and a phenomenological sedimentation/ erosion law. Different delta types are reproduced using different parameters and erosion rules. The structures of the calculated patterns are analyzed in space and time and compared with real data patterns. Furthermore our model is capable to simulate the rich dynamics related to the switching of the mouth of the river delta. The simulation results are then compared with geological records for the Mississippi river

The Combined Effect of Individualism – Collectivism on Conflict Styles and Satisfaction: An Analysis at the Individual Level

This research examines the relationships among individualism-collectivism (IND-COL), conflict management styles and conflict satisfaction. The authors aim to explain some of the inconclusive findings in the literature related to IND-COL and conflict styles by studying IND-COL as states, rather than dispositional traits. By taking a dynamic approach to conceptualizing IND-COL and measuring IND-COL over time, we investigate how different ratios of individualistic-to-collectivistic orientations are associated with different conflict management styles. Results show that individuals who employed a balanced focus (1:1 ratio) of both individualistic and collectivistic orientations utilized an integrative style in conflict more than individuals with either a strong individualistic or collectivistic orientation. Integrative style was associated with higher levels of satisfaction with conflict outcomes, processes, relationships, goal attainment and job satisfaction at work. Individuals with predominant focus on individualism utilized a dominating style more, whereas individuals with predominant focus on collectivism utilized obliging and avoiding styles. Furthermore, results show that state-level IND-COL is a better predictor of conflict management styles than trait-level IND-COL. Past research has focused on studying IND-COL primarily as a trait variable at the individual level, but we examine IND-COL as states in relation to conflict management styles. In addition, we investigate the combined and optimal effects of both individualism and collectivism value-orientations on conflict management styles

Scalable Microfabrication Procedures for Adhesive-Integrated Flexible and Stretchable Electronic Sensors.

New classes of ultrathin flexible and stretchable devices have changed the way modern electronics are designed to interact with their target systems. Though more and more novel technologies surface and steer the way we think about future electronics, there exists an unmet need in regards to optimizing the fabrication procedures for these devices so that large-scale industrial translation is realistic. This article presents an unconventional approach for facile microfabrication and processing of adhesive-peeled (AP) flexible sensors. By assembling AP sensors on a weakly-adhering substrate in an inverted fashion, we demonstrate a procedure with 50% reduced end-to-end processing time that achieves greater levels of fabrication yield. The methodology is used to demonstrate the fabrication of electrical and mechanical flexible and stretchable AP sensors that are peeled-off their carrier substrates by consumer adhesives. In using this approach, we outline the manner by which adhesion is maintained and buckling is reduced for gold film processing on polydimethylsiloxane substrates. In addition, we demonstrate the compatibility of our methodology with large-scale post-processing using a roll-to-roll approach

Noncommutative Q-balls

We obtain Q-ball solutions in noncommutative scalar field theory with a global U(1) invariance. The Q-ball solutions are shown to be classically and quantum mechanically stable. We also find that "excited Q-ball" states exist for some class of scalar potentials, which are classically stable in the large noncommutativity limit.Comment: 12 pages, LaTeX, v2: a typo corrected, v3: two references adde
