NUCLEUS develops, supports and implements inclusive and sustainable approaches to Responsible Research and Innovation within the governance and culture of research organisations in Europe. A major goal of the transdisciplinary project will be to stimulate research and innovation which continuously reflects and responds to societal needs. In order to achieve a multifaceted and cross-cultural New Understanding of Communication, Learning and Engagement in Universities and Scientific Institutions, 26 renowned institutions from 15 countries, among them leading representatives of 14 universities, will collaboratively identify, develop, implement and support inclusive and sustainable approaches to RRI. For a mutual learning and exchange process, the project will reach out beyond the European Research Area by including renowned scientific institutions in China, Russia and South Africa. Within a 4-year timeframe NUCLEUS will systematically uncover and analyse structural and cultural obstacles to RRI in scientific institutions. The partners will collaboratively develop innovative approaches to overcome these barriers. The project is expected to lead to an applicable RRI DNA, providing practical guidelines for higher education institutions and funding agencies across Europe and beyond. This DNA will form the basis for the NUCLEUS Living Network, an alliance to ensure sustainability of the approach beyond the project timeline. By offering new academic insights and practical recommendations derived from 30 RRI test beds, NUCLEUS will contribute to the debate on science policies both on a national and European level, including the future design of HORIZON 2020 and the European Research Area (ERA).

Over the last decade a sharp decline in interest and participation in science has been identified in young people across Europe. Should this continue, the capacity to innovate both in industry and research will suffer in the long term. A critical issue in addressing this problem is providing young people with relevant contexts and practical experience of scientific concepts through classroom science. Therefore, the development of Inquiry Based Science Education (IBSE) and active teaching and learning approaches has never been more important. The Chain Reaction project aims to capitalise on a previously successful approach to delivering IBSE in the UK in an attempt to embed IBSE practice within European schools. The key aim is to equip teacher educators to train teachers across twelve countries in the use of IBSE materials and techniques. Each country will adapt materials and techniques for use in their own country, addressing issues of different curricula and cultures as necessary. This will ensure that each partner will have ownership of resources and classroom techniques suitable for their own situation and contexts, but based around the proven principles of IBSE and based on materials that have already been tried and tested as part of the original Pupil Researcher Initiative (PRI) project. Chain Reaction will also establish a European teachers network, aimed at providing support to teachers, sharing experiences and expertise between teachers and training experts. This will help develop the work of the project through delivery, and will also contribute to sustainability in the longer term. The network will aid dissemination of the project resources and outcomes, while enabling peer support both within each year of the project, and across the project as a whole. This will ensure sharing, reflection and discussions of experiences and approaches. The teacher training, materials and instruction given will be delivered via a cascade approach within schools.

The PROFILES project promotes IBSE through raising the self-efficacy of science teachers and in so doing aiding a better understanding of the changing purpose of teaching science in schools and the value of stakeholder networking. The proposal innovation is in utilizing science teaching materials to support teachers, through an inspired, longitudinal training programme reflecting stakeholder views and needs, while simultaneously promoting a reflective IBSE school-based, training related, intervention to promote learning through creative, scientific problem solving and/or socio-scientific decision making procedures. The measures of success are through a) determining the self efficacy of science teachers in teaching innovative science education approaches allowing student acquisition of life skill competencies and b) in the attitudes of students toward this more context-led, student centered, IBSE-emphasised learning. Dissemination of approaches, reactions, and reflections form a further key project target. Initially PROFILES involves the development of science teachers on four fronts (teacher as learner, as teacher, as reflective practitioner and as leader) consolidating their ownership of the context-led approach and incorporating use-inspired research, evaluative methods and stakeholder networking. The project enhances its dissemination approaches with lead teachers spearheading training of further teachers at pre- and in-service levels and initiating workshops for key stakeholders nationwide. The project focuses on the secondary level so that open inquiry approaches are a major teaching target. PROFILE pays much attention to student motivation for the learning of science both in terms of intrinsic motivation (relevance, meaningful, as considered by the students) and extrinsic motivation (teacher encouragement and reinforcement) and attempts to make school science teaching more meaningful by paying attention to cultural differences, esp. at the gender level

The emergent gauge theories are reconsidered in light of supersymmetry and an appropriate emergence conjecture is formulated. Accordingly, it might be expected that only global symmetries are fundamental symmetries of nature, whereas local symmetries and associated massless gauge fields could solely emerge due to spontaneous breaking of the underlying spacetime symmetries involved, such as relativistic invariance and supersymmetry. We further argue that this breaking, taken in the form of the nonlinear σ-model-type pattern for vector fields or superfields, puts essential restrictions on geometrical degrees of freedom of a physical field system that makes it adjust itself in such a way that its global internal symmetry G turns into the local symmetry Gloc. Otherwise, a given field system could lose too many degrees of freedom, thus getting unphysical, which would make it impossible to set the required initial conditions in an appropriate Cauchy problem, or to choose self-consistent equal-time commutation relations in quantum theory. Remarkably, this emergence process may naturally be triggered by supersymmetry, as is illustrated in detail by an example of a general supersymmetric QED model which is then extended to the Standard Model and GUTs. The requirement of vacuum stability in such a class of models makes both Lorentz invariance and supersymmetry become spontaneously broken in the visible sector. As a consequence, the massless photon and other gauge bosons appear as the corresponding Goldstone and pseudo-Goldstone zero modes and special local invariance is simultaneously generated. Due to this invariance, all possible Lorentz violations turn out to be completely canceled out among themselves. However, broken supersymmetry effects related to the existence of a light pseudo-Goldstino (being essentially a photino) are still left in the theory. It typically appears in the low-energy particle spectrum as the eV-scale stable lightest supersymmetric particle or the electroweak-scale long-lived next-to-lightest supersymmetric particle, and in both cases it is accompanied by a very light gravitino that could be considered as some observational signature in favor of emergent supersymmetric theories. © 2014 American Physical Society.

We consider in detail the structure of quartic vertices for massless higher spin fields on Minkowski background, and study the consistency conditions imposed on cubic and quartic interactions by symmetries of the S-matrix. We discuss the possibility of generalizing the construction of quartic vertices to D-dimensional anti-de Sitter space. © 2012 Elsevier B.V.

We present Hilbert space representation for a relatively broad class of minimum-length deformed quantum mechanical models obtained by incorporating a space-time uncertainty relation into quantum mechanics. The correspondingly modified field theory is used for estimating the deviation of the light incoherence rate from distant astrophysical sources from the standard case. © 2012 American Physical Society.

For active galactic nuclei (AGNs), we study the role of the mechanism of quasi-linear diffusion (QLD) in producing the high-energy emission in the MeV-GeV domains strongly connected with the submillimeter/infrared radiation. Considering the kinetic equation governing the stationary regime of the QLD, we investigate the feedback of the diffusion on electrons. We show that this process leads to the distribution of particles by pitch angles, implying that the synchrotron mechanism is no longer prevented by energy losses. Examining a reasonable interval of physical parameters, we show that it is possible to produce MeV-GeV γ -rays that are strongly correlated with submillimeter/infrared bands. © 2010.

After picking out what may seem more realistic minimal gravitational deformation of quantum mechanics, we study its back reaction on gravity. The large distance behaviour of Newtonian potential coincides with the result obtained by using of effective field theory approach to general relativity (the correction proves to be of repulsive nature). The short distance corrections result in Planck mass black hole remnants with zero temperature. The deformation of position-momentum uncertainty relations leads to the superluminal motion that can be avoided by making similar deformation of time-energy uncertainty relation. Such deformation also avoids UV divergences in QFT. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

This paper presents a catalog of 312 X-ray selected BL Lacerate objects (XBLs), optically identified through the end of 2011. It contains the names from different surveys, equatorial coordinates, redshifts, multifrequency flux values, and luminosities for each source. In addition, the different characteristics of XBLs are statistically investigated (redshift, radio/optical/X-ray luminosities, central black hole (BH) mass, synchrotron peak frequency, broadband spectral indices, optical flux variability). Their values are collected through an extensive bibliographic and database search or calculated by us. The redshifts range from 0.031 to 0.702 with a maximum of the distribution at z = 0.223. The 1.4 GHz luminosities of XBLs log νL ν ∼ 39-42 erg s-1 while optical V and X-ray 0.1-2.4 keV bands show log νL ν ∼ 43-46 erg s-1. The XBL hosts are elliptical galaxies with effective radii r eff = 3.2625.40 kpc and ellipticities, ∈ = 0.040.52. Their R-band absolute magnitudes MR range from -21.11 mag to -24.86 mag with a mean value of -22.83 mag. The V-R indices of the hosts span from 0.61 to 1.52 and reveal a fourth-degree polynomial relationship with z that enables us to evaluate the redshifts of five sources whose V-R indices were determined from the observations but whose irredshifts values are either not found or not confirmed. The XBL nuclei show a wider range of 7.31 mag for MR with the highest luminosity corresponding to MR = -27.24 mag. The masses of central BHs are found in the interval log M BH = 7.39-9.30 solar masses (with distribution maximum at log MBH/M⊙ = 8.30). The synchrotron peak frequencies are spread over the range log νpeak = 14.56-19.18 Hz with a peak of the distribution at log νpeak = 16.60 Hz. The broadband radio-to-optical (αro ), optical-to-X-ray (αox ), and radio-to-X-ray (αrx ) spectral indices are distributed in the intervals (0.17,0.59), (0.56,1.48), and (0.41,0.75), respectively. In the optical energy range, the overall flux variability increases, on average, towards shorter wavelengths: 〈Δm〉 = 1.22, 1.50, and 1.82 mag through the R, V, B bands of Johnson-Cousins system, respectively. XBLs seem be optically less variable at the intranight timescales compared to the radio-selected BL Lacs (RBLs). © 2013. The American Astronomical Society. All rights reserved.

We study a grand unified SU(5)×SU(5)′ model supplemented by D2 parity. The D2 greatly reduces the number of parameters and is important for phenomenology. The model, we present, has various novel and interesting properties. Because of the specific pattern of grand unification symmetry breaking and emerged strong dynamics at low energies, the Standard Model leptons, along with right-handed/sterile neutrinos, come out as composite states. The generation of the charged fermion and neutrino masses are studied within the considered scenario. Moreover, the issues of gauge coupling unification and nucleon stability are investigated in details. Various phenomenological implications are also discussed. © 2014 American Physical Society.
