description: The reaction between carbon atoms and vinyl cyanide, CH2CHCN, is a formation route to interstellar 3-cyano propargyl radical, CH2C3N, a species that has recently been discovered in space. The 1-cyano propargyl radical (HC3HCN), an isomer of CH2C3N, is predicted to be produced in the same reaction at least twice more effciently than CH2C3N. Hence, HC3HCN is a plausible candidate to be observed in space as well. We aim to generate the HC3HCN radical in the gas phase in order to investigate its rotational spectrum. The derived spectroscopic parameters for this species will be used to obtain reliable frequency predictions to support its detection in space.The HC3HCN radical was produced by an electric discharge, and its rotational spectrum was characterized using a Balle-Flygare narrowband-type Fourier-transform microwave spectrometer operating in the frequency region of 4-40 GHz. The spectral analysis was supported by high-level ab initio calculations. A total of 193 hyperfine components that originated from 12 rotational transitions, a- and b-type, were measured for the HC3HCN radical. The analysis allowed us to accurately determine 22 molecular constants, including rotational and centrifugal distortion constants as well as the fine and hyperfine constants. Transition frequency predictions were used to search for the HC3HCN radical in TMC-1 using the QUIJOTE survey between 30.1-50.4 GHz. We do not detect HC3HCN in TMC-1 and derive a 3sigma upper limit to its column density of 6.0e11 cm-2.

description: Lossy transmission over a relay channel in which the relay has access to correlated side information is considered. First, a joint source-channel decode-and-forward scheme is proposed for general discrete memoryless sources and channels. Then the Gaussian relay channel where the source and the side information are jointly Gaussian is analyzed. For this Gaussian model, several new source-channel cooperation schemes are introduced and analyzed in terms of the squared-error distortion at the destination. A comparison of the proposed upper bounds with the cut-set lower bound is given, and it is seen that joint source-channel cooperation improves the reconstruction quality significantly. Moreover, the performance of the joint code is close to the lower bound on distortion for a wide range of source and channel parameters.

Creativity as opening toward new beginnings

Year: 2014

description: The initiative to organize an issue of Academic Quarter on creativity originates from the 32th International Human Science Research Conference (IHSRC), which took place at the University of Aalborg in the Northern Denmark in August 2013. Here the overall theme of the conference was ’Creativity in Human Science Research, Methodology and Theory’. More than 150 human scientists from all over the world participated in the conference in Denmark. According to the conference flyer:

All human sciences exist in a tension between tradition and renewal. At the conference, we hope that participants will discuss how to renew the human sciences creatively, and also to present ideas about what creativity is as a basic human phenomenon. How can phenomenological, hermeneutic and other human science traditions be respected and yet renewed in creative directions? How – and how much – should human scientists experiment with creative methodological practices when researching human phenomena? What role can the arts play? Are there limits to creativity? Can human beings become too creative – in life as well as in research? And what can human scientists actually contribute with to the current creativity discourse?

Many of those who have contributed to the present issue attended the conference.
 This issue raises a fundamental question that must be of importance for every human scientist: What is creativity really? And how can and why should a more ‘creative’ approach in human science be understood and defended? In what ways can phenomenology and hermeneutics become more open to insights into the nature of creativity and how should we talk about creative ways of doing phenomenology, hermeneutics, and human science as such?
In the current issue, you will find many different answers to what creativity is and what a creative human science approach could look like, and how to practice it. We have organized the content of this issue (28 articles) under four main themes


• Promoting Creativity

• Creativity and Research Methods

• Educational Approaches and Methods

• Design, Aesthetics and Creativity

description: The LUXE experiment aims at studying high-field QED in electron-laser and photon-laser interactions, with the 16.5 GeV electron beam of the European XFEL and a laser beam with power of up to 350 TW. The experiment will measure the spectra of electrons and photons in non-linear Compton scattering where production rates in excess of $10^9$ are expected per 1 Hz bunch crossing. At the same time positrons from pair creation in either the two-step trident process or the Breit--Wheeler process will be measured, where the expected rates range from $10^{-3}$ to $10^4$ per bunch crossing, depending on the laser power and focus. These measurements have to be performed in the presence of low-energy high radiation-background. To meet these challenges, for high-rate electron and photon fluxes, the experiment will use Cherenkov radiation detectors, scintillator screens, sapphire sensors as well as lead-glass monitors for back-scattering off the beam-dump. A four-layer silicon-pixel tracker and a compact sampling electromagnetic calorimeter will be used to measure the positron spectra. The layout of the experiment and the expected performance under the harsh radiation conditions will be presented.

description: We develop the cluster self-consistent field method incorporating both electronic and lattice degrees of freedom to study the origin of ferromagnetism in Cs$_{2}$AgF$_{4}$. After self-consistently determining the harmonic and anharmonic Jahn-Teller distortions, we show that the anharmonic distortion stabilizes the staggered x$^{2}$-z$^{2}$/y$^{2}$-z$^{2}$ orbital and ferromagnetic ground state, rather than the antiferromagnetic one. The amplitudes of lattice distortions, Q$_{2}$ and Q$_{3}$, the magnetic coupling strengthes, J$_{x,y}$, and the magnetic moment, are in good agreement with the experimental observation.

Creativity assessment as intervention

Year: 2014

description: Creativity, innovation, and entrepreneurship are among the most celebrated concepts in today’s world and this places them high on the agenda in the educational system. Everyone wants creativity, but few people have suggestions as to how to proceed developing or assessing it. This leaves educators around the world with the dilemma of how to integrate creativity, innovation and entrepreneurship into the curriculum. The present paper will discuss how current definitions of creativity and creativity assessment often stand in the way of working constructively towards this goal as they typically disconnect idea generation from idea evaluation and develop creativity measures that focus almost exclusively on divergent thinking. We will argue for a dynamic type of creativity assessment that considers it a developmental rather than purely diagnostic tool. Practical concerns regarding the assessment of creative learning will support these theoretical and methodological reflections.

description: This article draws on 20 Danish university students’ reflections in and on a Problem-based Learning process (PBL). The study showed how a more playful approach changed how the students collaborated, communicated, and approached a given task. They felt more creative, open minded and engaged compared to some of their earlier learning experiences. They sensed a change in how they interacted with each other, a different tone arose in their social bonding, which led to the overall question for this article: What happens when play becomes part of a PBL process and how can we understand the relation between play and creativity in higher education learning processes?

Quantum fields near phantom-energy `sudden' singularities
Creators: name: Calderon, Hector H.
Publisher: name: arXiv
Year: 2008
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: This paper is committed to calculations near a type of future singularity driven by phantom energy. At the singularities considered, the scale factor remains finite but its derivative diverges. The general behavior of barotropic phantom energy producing this singularity is calculated under the assumption that near the singularity such fluid is the dominant contributor. We use the semiclassical formula for renormalized stress tensors of conformally invariant fields in conformally flat spacetimes and analyze the softening/enhancing of the singularity due to quantum vacuum contributions. This dynamical analysis is then compared to results from thermodynamical considerations. In both cases, the vacuum states of quantized scalar and spinor fields strengthen the accelerating expansion near the singularity whereas the vacuum states of vector fields weaken it.

Year: 2014

description: Among scholars and practitioners interested in creative learning, many assumptions and even stereotypes are nurtured about artists’ creativity. The myth of the lone genius, for example, is neither close to artistic practices nor beneficial to education. We address the topic of artistic creativity, looking at its relevance to educational settings. Through asking the question: how do artists create, learn and how can education learn from them, we have investigated and described professional artists’ creative and learning processes. In this article, we present findings from a qualitative research project that explores these questions as an empirical and theoretical contribution to the field of arts and creativity research from a learning perspective. We found that the interviewed artists experience learning and the creative process as interwoven phenomena and that they develop intentional learning strategies that they use in the effort of creating works of art. One of the strategies, based on challenging oneself, is articulated in this article.

Spectral evolution of an eruptive polar crown prominence with IRIS observations

description: Prominence eruption is closely related to coronal mass ejections and is an important topic in solar physics. Spectroscopic observation is an effective way to explore the plasma properties, but the spectral observations of eruptive prominences are rare. In this paper we will introduce an eruptive polar crown prominence with spectral observations from the Interface Region Imaging Spectrograph (IRIS), and try to explain some phenomena that are rarely reported in previous works. The eruptive prominence experiences a slow-rise and fast-rise phase, while the line-of-sight motions of the prominence plasma could be divided into three periods: two hours before the fast-rise phase, opposite Doppler shifts are found at the two sides of the prominence axis;then, red shifts dominate the prominence gradually; in the fast-rise phase, the prominence gets to be blue-shifted. During the second period, a faint component appears in Mg II k window with a narrow line width and a large red shift. A faint region is also found in AIA 304-angstrom images along the prominence spine, and the faint region gets darker during the expansion of the spine. We propose that the opposite Doppler shifts in the first period are a feature of the polar crown prominence that we studied. The red shifts in the second period are possibly due to mass drainage during the elevation of the prominence spine, which could accelerate the eruption in return. The blue shifts in the third period are due to that the prominence erupts toward the observer. We suggest that the faint component appears due to the decreasing of the plasma density, and the latter results from the expansion of the prominence spine.

description: Persistent activity is postulated to drive neural network plasticity and learning. To investigate its underlying cellular mechanisms, we developed a biophysically tractable model that explains the emergence, sustenance, and eventual termination of short-term persistent activity. Using the model, we reproduced the features of reverberating activity that were observed in small (50-100 cells) networks of cultured hippocampal neurons, such as the appearance of polysynaptic current clusters, the typical inter-cluster intervals, the typical duration of reverberation, and the response to changes in extra-cellular ionic composition. The model relies on action potential-triggered residual presynaptic calcium, which we suggest plays an important role in sustaining reverberations. We show that reverberatory activity is maintained by enhanced asynchronous transmitter release from pre-synaptic terminals, which in itself depends on the dynamics of residual presynaptic calcium. Hence, asynchronous release, rather than being a "synaptic noise", can play an important role in network dynamics. Additionally, we found that a fast timescale synaptic depression is responsible for oscillatory network activation during reverberations, whereas the onset of a slow timescale depression leads to the termination of reverberation. The simplicity of our model enabled a number of predictions that were confirmed by additional analyses of experimental manipulations.
Force and length-dependent catastrophe activities explain interphase microtubule organization in fission yeast

description: The cytoskeleton is essential for the maintenance of cell morphology in eukaryotes. In fission yeast for example, polarized growth sites are organized by actin whereas microtubules (MT) acting upstream control where growth occurs (La Carbona et al, 2006). Growth is limited to the cell poles when MTs undergo catastrophes there and not elsewhere on the cortex (Brunner and Nurse, 2000). Here we report that the modulation of MT dynamics by forces as observed in vitro (Dogterom and Yurke, 1997; Janson et al, 2003) can quantitatively explain the localization of MT catastro-phes in S. pombe. However, we found that it is necessary to add length-dependent catastrophe rates to make the model fully consistent with other measured traits of MTs. This result demonstrates the possibility that MTs together with associated proteins such as kinesins having a depolymerization activity can reliably mark the tips of the cell.

description: This article develops a framework for understanding the creation of online content on social media sites. Focusing on creativity and its social context, the study is narrowed to the field of fanfiction and fanfiction sites. Using the Systems Model of Creativity by Csikszentmihalyi as a template, this article analyses roles, processes, and products found in fanfiction communities and on fanfiction sites. The specific needs for motivation and support of especially the writer and the collective (Thomas & Brown, 2011) surrounding them are looked upon and compared to the present functionality and usability of the fanfiction sites in question. Further, I elaborate on how the infrastructure of the different sites, as well as their possibilities for interaction, encourage or discourage collaborative creativity, as well as participation in the development of the stories. Finally, a modified Systems Model is presented, containing the preliminary findings.

This function is continuous at every irrational point, while at rational points, left-continuous but not right-continuous. Moreover, it assumes algebraic integers at rationals, and transcendental numbers at irrationals. We also see that the differentiation of $Δ$ distinguishes some irrationality measures of real numbers.

description: Layered materials enable the assembly of a new class of heterostructures where lattice-matching is no longer a requirement. Interfaces in these heterostructures therefore become a fertile ground for unexplored physics as dissimilar phenomena can be coupled via proximity effects. In this article we identify an unexpected photoluminescence (PL) peak when MoSe$_2$ interacts with TiSe$_2$. A series of temperature-dependent and spatially-resolved PL measurements reveal this peak is unique to the TiSe$_2$-MoSe$_2$ interface, higher in energy compared to the neutral exciton, and exhibits exciton-like characteristics. The feature disappears at the TiSe$_2$ charge density wave transition, suggesting that the density wave plays an important role in the formation of this new exciton. We present several plausible scenarios regarding the origin of this peak that individually capture some aspects of our observations, but cannot fully explain this feature. These results therefore represent a fresh challenge for the theoretical community and provide a fascinating way to engineer excitons through interactions with charge density waves.

Farm Management

description: A number of theories have been proposed for managing risks. However, the lack of standard measures of risk in the past have made it difficult for farmers to apply risk management strategies in their decision making process. Risk-rated farm enterprise budgets provide a method of measuring risks and comparing the riskness of various alternatives. The risk-rated approach to risk management is designed to deal with the ever present possibility of prices and yields less favorable than expected. Good decisions can result in losses even when risks are taken into consideration. However, the chances of making decisions that turn out to be profitable can be greatly improved by the evaluation of potential profits and risks among logical alternatives.

description: Modern farm animal management requires accurate planning of production and its consequent realization. This is based on biological functions as prerequisites for the various forms of farm animal utilization. Biotechnical procedures may be defined as measures for monitoring, controlling, modifying and manipulating biological functions with relevance to animal production. Thus, they may render important contributions to the facilitation of farm animal management. The application of biotechnical procedures and its related problems are discussed for management aspects in the fields of reproduction, meat and milk production as well as animal health and welfare. The perspectives for practical employment of biotechnology are different, but altogether within the framework of realistic application models.
Their application however, has to include considerations concerning ecological as well as legislative and ethical principals.

description: The winds observed around AGB stars are generally attributed to radiation pressure on dust formed in the dynamical atmospheres of these long-period variables. The composition of wind-driving grains is affected by a feedback between their optical properties and the resulting heating due to stellar radiation. We explore the gradual Fe enrichment of wind-driving silicate grains in M-type AGB stars to derive typical values for Fe/Mg and test the effects on wind properties and synthetic spectra. We present new DARWIN models that allow for the growth of silicate grains with a variable Fe/Mg ratio and predict mass-loss rates, wind velocities, and grain properties. Synthetic spectra and other observables are computed with the COMA code. The self-regulating feedback between grain composition and radiative heating, in combination with quickly falling densities in the stellar wind, leads to low values of Fe/Mg, typically a few percent. Nevertheless, the models show distinct silicate features around 10 and 18 microns. Fe enrichment affects visual and near-IR photometry moderately, and the new DARWIN models agree well with observations in (J-K) vs. (V-K) and Spitzer color-color diagrams. The enrichment of the silicate dust with Fe is a secondary process, taking place in the stellar wind on the surface of large Fe-free grains that have initiated the outflow. Therefore, the mass-loss rates are basically unaffected, while the wind velocities tend to be slightly higher than in corresponding models with Fe-free silicate dust. The gradual Fe enrichment of silicate grains in the inner wind region should produce signatures observable in mid-IR spectro-interferometrical measurements. Mass-loss rates derived from existing DARWIN models, based on Fe-free silicates, can be applied to stellar evolution models since the mass-loss rates are not significantly affected by the inclusion of Fe in the silicate grains.

description: We use lattice QCD simulations, with MILC gluon configurations and HISQ c-quark propagators, to make very precise determinations of moments of charm-quark pseudoscalar, vector and axial-vector correlators. These moments are combined with new four-loop results from continuum perturbation theory to obtain several new determinations of the MSbar mass of the charm quark and of the MSbar coupling. We find m_c(3GeV)=0.986(10)GeV, or, equivalently, m_c(m_c)=1.268(9)GeV, both for n_f=4 flavors; and alpha_msb(3GeV,n_f=4)=0.251(6), or, equivalently, alpha_\msb(M_Z,n_f=5)=0.1174(12). The new mass agrees well with results from continuum analyses of the vector correlator using experimental data for e+e- annihilation (instead of using lattice QCD simulations). These lattice and continuum results are the most accurate determinations to date of this mass. Ours is also one of the most accurate determinations of the QCD coupling by any method.

description: This document contains a set of design principles and a toolkit with methods for designing science learning activities that take place outside the classroom, in spaces such as science centres, makerspaces, museums, galleries, and gardens. The Design Principles and Methods Toolkit are aimed at science educators, coordinators and facilitators working in a diversity of contexts associated with science learning. This toolkit hopes to aid the design and facilitation of meaningful science learning activities and programs, with an emphasis on nurturing inclusive science learning. To the best of our knowledge, to date there is not a similar resource available specifically focused on science learning outside the classroom. Thus, we hope that the Design Principles and Methods Toolkit will contribute to the professional development of those involved in nonformal science education by triggering reflection about pedagogical design and practice.

description: Multiple applications that execute concurrently on heterogeneous platforms compete for CPU and network resources. In this paper we analyze the behavior of $K$ non-cooperative schedulers using the optimal strategy that maximize their efficiency while fairness is ensured at a system level ignoring applications characteristics. We limit our study to simple single-level master-worker platforms and to the case where each scheduler is in charge of a single application consisting of a large number of independent tasks. The tasks of a given application all have the same computation and communication requirements, but these requirements can vary from one application to another. In this context, we assume that each scheduler aims at maximizing its throughput. We give closed-form formula of the equilibrium reached by such a system and study its performance. We characterize the situations where this Nash equilibrium is optimal (in the Pareto sense) and show that even though no catastrophic situation (Braess-like paradox) can occur, such an equilibrium can be arbitrarily bad for any classical performance measure.
Managing, Protecting and Developing the Rural Environment Farming and Wildlife Advisory Group's - Conservation Advice Through Partnership
Creators: name: Carter, Eric S.

Year: 1988
Subjects: Environmental Economics and Policy

description: The present era of secure food supplies and the need to control production encourages criticism of farming methods and technology, land-use and the role of farming in relation to forestry, wilderness areas and public access. Over a period of many years farmers have received advice and training in agricultural technology but this has rarely included environmental issues. If changes in land-use and agricultural production techniques are to be brought about and farmers encouraged to devote greater care to wildlife and landscape conservation, then they will need to understand why this is necessary and to receive advice on how to do it. Such advice must be related to their agricultural background and the management of individual farms taking into account the resources available.

description: We provide a review on the state-of-the-art of gravitational waves induced by primordial fluctuations, so-called induced gravitational waves. We present the intuitive physics behind induced gravitational waves and we revisit and unify the general analytical formulation. We then present general formulas in a compact form, ready to be applied. This review places emphasis on the open possibility that the primordial universe experienced a different expansion history than the often assumed radiation dominated cosmology. We hope that anyone interested in the topic will become aware of current advances in the cosmology of induced gravitational waves, as well as becoming familiar with the calculations behind.

The effect of the patient’s level of consciousness and the degree of nasogastric tube flexibility on the ease of insertion of the tube in patients with an endotracheal tube in place
Creators: name: Heaslip, Jane Elizabeth

description: The purpose of this study was to examine the effect that the patient's level of consciousness and the degree of nasogastric tube flexibility would have on the ease of insertion of the tube in patients with an endotracheal tube in place. The statistical hypotheses tested were: 1. The Degree of nasogastric tube flexibility will not influence the ease with which the tube is inserted. 2. The level of consciousness of the patient will not influence the ease with which the nasogastric tube is inserted. 3. There will be no interaction between the degree of flexibility of the nasogastric tube to be inserted and the level of consciousness of the patient in whom the tube is placed. The sample from whom data was collected for the study consisted of 121 patients admitted to the respiratory intensive care unit of a large teaching hospital who required endotrachea intubation and subsequent placement of a nasogastric tube. The number of attempts per patient for successful placement of each tube were recorded over a four month period and the data analysed using a 2 X 3 factorial design. The two independent variables were degree of nasogastric tube flexibility with two levels: flexible and rigid, and level of consciousness with three levels: conscious, obtunded and unconscious. The data collected from the study indicate that the degree of nasogastric tube flexibility significantly affects the ease with which a tube can be inserted in an intubated patient (α=.05) the rigid tube requiring a statistically fewer number of attempts than the flexible tube. The difference among levels of patient consciousness were not found to be statistically significant in this investigation but the interaction between the degree of tube flexibility and level of patient consciousness revealed statistical significance.

description: The remarkable single particle control of individual ions combined with the versatility of ultracold atomic gases makes hybrid ion-atom system an exciting new platform for quantum simulation of few- and many-body quantum physics. Here, we study theoretically the properties of a mobile ion immersed in a quantum degenerate gas of fermionic atoms. Using an effective low-energy atom-ion interaction together with a well established approach that includes exactly two-body correlations, we calculate the full spectral response of the ion and demonstrate the existence of several quasiparticle branches, which are charged analogues of the Fermi polaron observed in neutral atomic gases. Due to the long-range nature of the atom-ion interaction, these ionic Fermi polarons have several properties distinct from their neutral counterparts such as the simultaneous presence of several stable states and smooth transitions from repulsive to attractive polarons with increasing interaction strength. Surprisingly, the residue of the ionic polaron is shown to increase with the Fermi density for fixed interaction strength, which is in marked contrast to the neutral polaron. The properties of the ionic polaron approach that of the neutral polaron only in the low density limit where the average interparticle spacing is larger than the characteristic length of the atom-ion interaction. We finally analyse the effects of the Fermi gas on the molecular ions, which are bound atom-dimer states.
