description: We have measured the Stark shift of the $A^2Π_{1/2} - X^2Σ^+$ transition in YbF. We use a molecular beam triple resonance method, with two laser transitions acting as pump and probe, assisted by an rf transition that tags a single hyperfine transition of the X state. After subtracting the known ground state Stark shift, we obtain a value of $70.3(1.5) $Hz/(V/cm)$^2$ for the static electric polarizability of the state $A^2Π_{1/2}(J=1/2,f)$. From this we calculate a value $μ_e=2.46(3)$D for the electric dipole moment of the $A^2Π_{1/2}(v=0)$ state.

description: A non--minimally coupled quintessence model is investigated and the conditions for a stationary solution to the coincidence problem are obtained. For a conformally coupled scalar field and dissipative matter, a general solution possessing late acceleration is found. It fits rather well the high redshift supernovae data and gives a good prediction of the age of the Universe. Likewise, the cold dark matter component dominates the cosmological perturbations at late times albeit they decrease with expansion.

description: Processes commonly studied at the Large Hadron Collider (LHC) are induced by quarks and gluons inside the protons of the LHC beams. In this letter we demonstrate that, since protons also contain leptons, it is possible to target lepton-induced processes at the LHC as well. In particular, by picking a lepton from one beam and a quark from the other beam, we present for the first time a comprehensive analysis of resonant single leptoquark (LQ) production at a hadron collider. In the case of minimal scalar LQs, we derive novel bounds that arise from the LHC Run II considering all possible flavour combinations of an electron or a muon and an up ($u$), a down ($d$), a strange or a charm quark. For the flavour combinations with a $u$ or a $d$ quark, the obtained limits represent the most stringent constraints to date on LQs of this type. The prospects of our method at future LHC runs are also explored. Given the discovery reach of the proposed LQ signature, we argue that dedicated resonance searches in final states featuring a single light lepton and a single light-flavour jet should be added to the exotics search canon of both the ATLAS and the CMS collaboration.

MIGNEX Handbook Chapter 4 - Research ethics and research integrity

description: Research ethics and research integrity are not only a matter of compliance. They are also ideals that inspire reflection on how we carry out research and communicate insights to audiences with diverging views on migration and its links with development.

Key Takeaways

It can be hard to tell which research participants are most vulnerable and which information is most sensitive. Sound general safeguards are therefore needed.

There is not always a ‘correct’ response to challenges related to ethics and integrity. It is nevertheless important to recognize them and be deliberate in our approach.

Tensions with implications for research ethics and research integrity emerge in the intersection of migration research, migration policy and migration politics.
Control of cardiovascular function during prolonged anoxia exposure in the freshwater turtle (Trachemys scripta)
Creators: name: Stecyk, Jonathan Anthony William
Publisher: name: University of British Columbia
Year: 2011

description: Unlike the majority of vertebrates, the freshwater turtle (Trachemys scripta) can survive anoxia for hours at warm acclimation temperatures and weeks at cold acclimation temperatures. During anoxia exposure, the turtle heart continues its role in internal convection, but systemic cardiac output and systemic cardiac power output are massively reduced, primarily due to a decreased heart rate (ƒH). Therefore, control of ƒH is critical to cardiac energy management during anoxia. This thesis investigated what extrinsic, autocrine/paracrine and intrinsic mechanisms control the cardiovascular system of anoxic freshwater turtles. Cardiac control was examined at the level of the whole animal, organ (isolated heart chambers), and cell (isolated cardiac myocytes). A 2 x 2 exposure design allowed comparisons between 21°C- and 5°C-acclimated turtles under normoxia and anoxia. For warm-acclimated turtles, I discovered a re-setting of intrinsic ƒH that accounts for up to 57% of the anoxic bradycardia, which, when combined with cholinergic cardiac inhibition (previously known), fully explains the depression of ƒH with anoxia. Interestingly, prolongation of ventricular action potential duration (APD) by 47% with anoxia was proportional to the reduction in intrinsic ƒH. My thesis also revealed how cold acclimation prepared cardiac muscle for winter anoxic conditions. Cold temperature decreased intrinsic ƒH, prolonged cardiac APDs and reduced the chronotropic sensitivity to extracellular anoxia and acidosis. Also, the decreased peak densities of ventricular I[sub Na] and I[sub Ca] and conductance of i[sub KI] observed in 5°C-acclimated turtle hearts compared with 21°C-acclimated turtle hearts could serve to conserve the ATP cost of ion pumping. When cold-acclimated turtles were exposed to anoxia, during which cholinergic cardiovascular control is blunted, my thesis discovered that a re-setting of intrinsic ƒH accounts for up to 66% of the anoxic bradycardia. However, contrary to 21°C, there was no prolongation of cardiac APDs. No evidence was found for either α-adrenergic or adenosinergic cardiac inhibition in cold-acclimated anoxic turtles, yet their reduction of in vivo cardiac activity correlated with alterations in myocardial high-energy phosphate metabolism, intracellular pH and free energy of ATP hydrolysis. These novel insights point to the importance of future studies on pacemaker currents and cardiac refractoriness.

description: In extension of the bit commitment task and following work initiated by Crepeau and Kilian, we introduce and solve the problem of characterising the optimal rate at which a discrete memoryless channel can be used for bit commitment. It turns out that the answer is very intuitive: it is the maximum equivocation of the channel (after removing trivial redundancy), even when unlimited noiseless bidirectional side communication is allowed. By a well-known reduction, this result provides a lower bound on the channel's capacity for implementing coin tossing, which we conjecture to be an equality. The method of proving this relates the problem to Wyner's wire--tap channel in an amusing way. We also discuss extensions to quantum channels.

description: Associated to an arrangement of projective hyperplanes A is the module D(A), which consists of derivations tangent to A. We study D(A) when A is a configuration of lines in the projective plane. In this setting, we relate the deletion/restriction construction used in the study of hyperplane arrangements to elementary modifications of bundles. This allows us to obtain bounds on the Castelnuovo-Mumford regularity of D(A). We also give simple combinatorial conditions for the associated bundle to be stable, and describe its jump lines. These regularity bounds and stability considerations impose constraints on Terao's conjecture.

description: La valorización de activos financieros ha sido tradicionalmente un proceso basado en modelos estadísticos y matemáticos clásicos. Sin embargo, en los últimos años, la Inteligencia Artificial (IA) y el Machine Learning (ML) han emergido como herramientas disruptivas que transforman este campo. Este artículo explora el impacto de la IA y el ML en la valoración de activos financieros, analizando cómo estas tecnologías mejoran la precisión, la eficiencia y la capacidad predictiva de los modelos tradicionales.La IA y el ML permiten procesar grandes volúmenes de datos no estructurados, como informes financieros, noticias del mercado y redes sociales, que pueden influir significativamente en los precios de los activos. Gracias a los algoritmos de aprendizaje automático, se pueden identificar patrones complejos y no lineales que los modelos convencionales no logran captar, lo que aumenta la capacidad de prever el comportamiento de los mercados financieros.Además, la capacidad de la IA para adaptarse a nuevos datos y la mejora continua de los modelos a través del aprendizaje hace que la valoración de activos sea más dinámica y ajustada a las condiciones cambiantes del mercado. Este enfoque también ayuda a la automatización del proceso de valoración, reduciendo los costos operativos y mejorando la toma de decisiones en tiempo real.En conclusión, la integración de la IA y el ML en la valoración de activos financieros no solo optimiza los procesos de análisis, sino que también abre nuevas posibilidades en el ámbito de la predicción financiera.

description: We study the final state of the gravitational collapse of uniformly rotating supramassive neutron stars by axisymmetric simulations in full general relativity. The rotating stars provided as the initial condition are marginally stable against quasiradial gravitational collapse and its equatorial radius rotates with the Kepler velocity (i.e., the star is at the mass-shedding limit). To model the neutron stars, we adopt the polytropic equations of state for a wide range of the polytropic index as $n=2/3$, 4/5, 1, 3/2 and 2. We follow the formation and evolution of the black holes, and show that irrespective of the value of $n (2/3\leq n \leq 2)$, the final state is a Kerr black hole and the disk mass is very small ($< 10^{-3}$ of the initial stellar mass).

description: The present investigation reports evaluation of phytochemical content, antimicrobial, antioxidant, antidiabetic and anticancer properties of the methanolic crude extracts prepared from Memecylon randerianum leaves. Qualitative evaluation showed the presence of carbohydrates, reducing sugars, alkaloids, phenols, flavonoids, cardiac glycosides, steroids, phytosterols, terpenoids, diterpenoids and coumarins. Quantitative estimation for phenols, flavonoids and alkaloids indicated total phenolic content 11.95 mg GAE/g, total flavonoid content 20.34 mg QE/g and total alkaloid content 316.68 mg AE/g dry weight of the crude extract respectively. The methanolic extract demonstrated effective antimicrobial activity against Escherichia coli, Staphylococcus aureus and Candida albicans. The preparation also demonstrated good antioxidant and antidiabetic activities. Anticancer activity was evaluated against breast (MCF), oral (KB) and lung (A-549) cancer cell lines and the respective IC50 values were found to be 159.81 ± 7.54 µg/mL, 240.21 ± 2.57 µg/mL and 124.17 ± 2.10 µg/mL which are comparable to IC50 values of Paclitaxel.

description: Context: Radio-sensitivity in normal tissue is characterized by heterogeneity throughout the population and the absence of pre-diagnostic biomarkers. Objective: We conducted a proteomic approach to search for radiation characteristic protein regulation. Materials and methods: Cell lines were 10 Gy irradiated and analysed by 2D-DIGE after 24 h. Results were analysed intra- and inter-individually. The principal component analysis and hierarchical clustering was applied to all datasets. Results: Differences in intra-individual spot abundance prior and post irradiation exactly show the separation of sample classes in two groups: sham-irradiated and irradiated. The inter-individual datasets clustered according to the cell line. The intra-individual differences on protein level after gamma-irradiation are very low, compared with the inter-individual differences among cell lines derived from the same tissue. Conclusion: The application of 2-D DIGE may offer a realistic chance for a better molecular characterization of radio-sensitivity and for the discovery of candidate biomarkers.

Magnetically driven outflows from Jovian circum-planetaryaccretion disks

Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We discuss the possibility to launch outflows from the close vicinity of a protoplanetary core considering a scenario where the protoplanet surrounded by a circum-planetary accretion disk is located in a circum-stellar disk. For the circum-planetary disk accretion rate we assume 6x10^{-5} M_jup/yr, implying peak disk temperatures of about 2000K. The estimated disk ionization degree and Reynolds number allow for a sufficient coupling between the disk matter and the magnetic field. We find that the surface magnetic field strength of the protoplanet is probably not more than 10 G, indicating that the global planetary magnetosphere is dominated by the circum-planetary disk magnetic field below 50 G. The estimated field strength and mass flow rates allow for asymptotic outflow velocities of 60 km/s. The overall outflow geometry will resemble a hollow tube or cone perpendicular the disk. Outflows from circum-planetary disks may be visible in shock excited emission lines along a tube of diameter of the orbital radius and thickness of about 100 protoplanetary radii. Energetically, protoplanetary outflows cannot survive the interaction with a protostellar outflow. Due to the efficient angular momentum removal by the outflow, we expect the protoplanetary outflow to influence the early planet angular momentum evolution.

description: This research explores the intersection between alternative food and editorial design. To investigate this gap, it proposes generating a body of editorial expressions that embody a series of alternative food narratives found in local contexts in Mexico City and Vancouver. The study is grounded on the necessity of looking for alternative ways to relate to food and considers the editorial design practice as a critical mechanism to empower that shift. This is based on the premise that awareness of alternative food practices is necessary to change the negative impacts of the current conventional food system that are affecting our lands, bodies and cultures. This research considers a practice-based methodology that includes reflective practice and design methods, as well as literature review, field research, empirical observation, social engagement and conversations with food producers. The research centers on a body of editorial work related to typography, photography, and illustration that inquires about bringing alternative food narratives into the creative practice of editorial design.

description: The flat pp-wave background geometry has been realized as a particular Penrose limit of AdS_5 x S^5. It describes a string that has been infinitely boosted along an equatorial null geodesic in the S^5 subspace. The string worldsheet Hamiltonian in this background is free. Finite boosts lead to curvature corrections that induce interacting perturbations of the string worldsheet Hamiltonian. We develop a systematic light-cone gauge quantization of the interacting worldsheet string theory and use it to obtain the interacting spectrum of the so-called `two-impurity' states of the string. The quantization is technically rather intricate and we provide a detailed account of the methods we use to extract explicit results. We give a systematic treatment of the fermionic states and are able to show that the spectrum possesses the proper extended supermultiplet structure (a non-trivial fact since half the supersymmetry is nonlinearly realized). We test holography by comparing the string energy spectrum with the scaling dimensions of corresponding gauge theory operators. We confirm earlier results that agreement obtains in low orders of perturbation theory, but breaks down at third order. The methods presented here can be used to explore these issues in a wider context than is specifically dealt with in this paper.

description: The transcription factor sterol regulatory element binding protein (SREBP)-1c plays a pivotal role in lipid metabolism. In this report we identified the main phosphorylation sites of MAPK-families, i.e. p38 stress-activated MAPK (p38), ERK-MAPK (ERK) or c-JUN N-terminal protein kinases (JNK) in SREBP-1c. The major phosphorylation sites of p38, i.e. serine 39 and threonine 402, are identical to those we recently identified in the splice-variant SREBP-1a. In contrast, ERK and JNK phosphorylate SREBP-1c at two major sites, i.e. threonine 81 and serine 93, instead of one site in SREBP-1a. Functional analyses of the biological outcome in the human liver cell line HepG2 reveals SREBP-1c phosphorylation dependent alteration in lipid metabolism and secretion pattern of lipid transporting proteins, e.g. ApoE or ApoA1. These results suggest that phosphorylation of SREBP-1c by different MAPKs interferes with lipid metabolism and the secretory activity of liver cells.

description: Quantum singularities in general relativistic spacetimes are determined by the behavior of quantum test particles. A static spacetime is quantum mechanically singular if the spatial portion of the wave operator is not essentially self-adjoint. Here Weyl's limit point-limit circle criterion is used to determine whether a wave operator is essentially self-adjoint. This test is then applied to scalar wave packets in Levi-Civita spacetimes to help elucidate the physical properties of the spacetimes in terms of their metric parameters.

description: For assemblies of superconductor nanograins, the magnetic response is analyzed as a function of both temperature and magnetic field. In order to describe the interaction energy of electron pairs for a huge number of many-particle states, involved in calculations, we develop a simple approximation, based on the Richardson solution for the reduced BCS Hamiltonian and applicable over a wide range of the grain sizes and interaction strengths at arbitrary distributions of single-electron energy levels in a grain. Our study is focused upon ultra-small grains, where both the mean value of the nearest-neighbor spacing of single-electron energy levels in a grain and variations of this spacing from grain to grain significantly exceed the superconducting gap in bulk samples of the same material. For these ultra-small superconductor grains, the overall profiles of the magnetic susceptibility as a function of magnetic field and temperature are demonstrated to be qualitatively different from those for normal grains. We show that the analyzed signatures of pairing correlations are sufficiently stable with respect to variations of the average value of the grain size and its dispersion over an assembly of nanograins. The presence of these signatures does not depend on a particular choice of statistics, obeyed by single-electron energy levels in grains.

title: The moderating influence of social factors in impulsive buying behaviour: development of a scale to measure social and non-social impulsive buying tendencies
Creators: name: Shawcross, Matthew Stuart
Publisher: name: The Open University

description: Impulsive behaviour accounts for a significant percentage of retail sales, yet it may contribute to consumer debt and affect psychological wellbeing. Existing research indicates that impulsive buying presents as trait behaviour that influences the likelihood of experiencing impulsive urges and making purchases. Many studies have also examined the interaction of different variables with the impulsive buying tendency and the effects on behaviour during shopping. However, there is a lack of research into how social and emotional factors interact with or moderate the impulsive buying process. Accordingly, this thesis focuses on the role of social influence and emotion in impulsive buying. A mixed-methods approach is used, comprising a three stage data collection process involving interviews, scale development and a quasi-experiment. The data collection process leads to the development of two scales measuring social and non-social impulsive buying tendencies. These new tendencies are initially identified through semi-structured interviews with impulsive buyers, which suggest that there may be social and non-social aspects to the impulsive buying tendency. A two phase process of scale development is then used to develop psychometric measures of the social and non-social aspects. The scale development results in two internally valid and reliable scales which correlate as expected with the existing impulsive buying tendency. The scales are tested using a quasi-experimental study, the results of which indicate that the social impulsive buying tendency exhibits stronger correlations with hypothesised behaviour in social situations than the existing buying impulsiveness scale (Rook & Fisher, 1995). These findings suggest that the social scale could be used alongside an existing impulsive buying tendency scale to record consumers' social and non-social impulsivity. Among the implications of these findings is that researchers who study impulsive buying should consider recording the social context of shopping to test for the moderating influence of social factors.

DESCRIPTION OF HOLOTYPE
 Length: 8.2 mm; length of elytra: 5.9 mm; width: 4.2 mm. Body surface brown with greenish shine. Head and antenna as in E. metallica; eyes small, ratio of diameter/interocular width: 0.58. Antennomeres 3-5 not fused; club a little longer than the remaining antennomeres combined. Pronotum and scutellum as in E. metallica, except the basal marginal line of pronotum being more distinct and widely interrupted medially and its surface bearing a single long seta on the center of each pronotal half. Elytra as in E. metallica. Metacoxa and pygidium as in E. metallica. Ratio of length of metepisternum/ metacoxa: 1/1.89. Legs as in E. metallica; ratio of metatibial width/length: 1/4.17, medial face of metatibia with one or two punctures beside the dorsal margin.
Aedeagus: Figure 1 E-G.
VARIATION
Length: 8.2-9.9 mm; length of elytra: 5.9-6.2 mm; width: 4.2-5.3 mm. The colour varies from blackish green to reddish purple. The female has the antennal club slightly shorter and the punctures on pygidium are very indistinct.
 REMARKS The species is very similar in external morphology to E. metallica and may externally only be distinguished by the unfused antennomeres 3-5. The shape of parameres provides more confidence for separating both taxa; parameres are longer in E. lacroixi n. sp. with a widely curved apical hook.

description: We demonstrate that megaton-mass neutrino telescopes are able to observe the signal from long-lived particles beyond the Standard Model, in particular the stau, the supersymmetric partner of the tau lepton. Its signature is an excess of charged particle tracks with horizontal arrival directions and energy deposits between 0.1 and 1 TeV inside the detector. We exploit this previously-overlooked signature to search for stau particles in the publicly available IceCube data. The data shows no evidence of physics beyond the Standard Model. We derive a new lower limit on the stau mass of $320$ GeV (95\% C.L.) and estimate that this new approach, when applied to the full data set available to the IceCube collaboration, will reach world-leading sensitivity to the stau mass ($m_{\tildeτ}=450\,\mathrm{GeV}$).

description: The question of how perturbations evolve through a bounce in the Cyclic and Ekpyrotic models of the Universe is still a matter of ongoing debate. In this report we show that the collision between boundary branes is in most cases singular even in the full 5-D formalism, and that first order perturbation theory breaks down for at least one perturbation variable. Only in the case that the boundary branes approach each other with constant velocity shortly before the bounce, can a consistent, non singular solution be found. It is then possible to follow the perturbations explicitly until the actual collision. In this case, we find that if a scale invariant spectrum developed on the hidden brane, it will get transferred to the visible brane during the bounce.

description: Percolation with edge-passage probability p and first-passage percolation are studied for the n-cube B_n ={0,1}^n with nearest neighbor edges. For oriented and unoriented percolation, p=e/n and p=1/n are the respective critical probabilities. For oriented first-passage percolation with i.i.d. edge-passage times having a density of 1 near the origin, the percolation time (time to reach the opposite corner of the cube) converges in probability to 1 as n->infty. This resolves a conjecture of David Aldous. When the edge-passage distribution is standard exponential, the (smaller) percolation time for unoriented edges is at least 0.88. These results are applied to Richardson's model on the (unoriented) n-cube. Richardson's model, otherwise known as the contact process with no recoveries, models the spread of infection as a Poisson process on each edge connecting an infected node to an uninfected one. It is shown that the time to cover the entire n-cube is bounded between 1.41 and 14.05 in probability as n->infty.

description: An optoelectronic optimization was carried out for an AlGaAs solar cell containing (i) an n-AlGaAs absorber layer with a graded bandgap and (ii) a periodically corrugated Ag backreflector combined with localized ohmic Pd-Ge-Au backcontacts. The bandgap of the absorber layer was varied either sinusoidally or linearly. An efficiency of 33.1% with the 2000-nm-thick n-AlGaAs absorber layer is predicted with linearly graded bandgap along with silver backreflector and localized ohmic backcontacts, in comparison to 27.4% efficiency obtained with homogeneous bandgap and a continuous ohmic backcontact. Sinusoidal grading of the bandgap {is predicted to enhance} the maximum efficiency to 34.5%. Thus, grading the bandgap of the absorber layer, along with a periodically corrugated Ag backreflector and localized ohmic Pd-Ge-Au backcontacts can help realize ultrathin and high-efficient AlGaAs solar cells for terrestrial applications.
title: The academic middle manager in higher education : perceptions and aspirations
Creators: name: Oldman, Crystal Elizabeth
Publisher: name: The Open University
Year: 2014

description: This thesis examines the knowledge, skills and attributes required by middle managers in higher education institutions and the aspirations of academics to move to a management position. Taking a grounded theory approach to the design of the study and the analysis of the findings, 26 middle managers from three 'post 1992' universities in England were interviewed in depth about their positions and their views on the knowledge, skills and attributes required in delivering their roles. An illustrative model was developed from the analysis of the interview data to demonstrate the relationship between the elements identified in the study as essential in the delivery of the middle manager's role. The support and development needs of managers were identified along with the unexpected finding that managers from industry could enter higher education successfully with no prior experience of employment in the sector. In parallel with the interviews, the academic communities of the three universities were offered the opportunity to complete a survey to provide some contextual material on their perceptions of management in higher education and their aspirations to become managers in their future careers. The findings of the study are relevant to human resource departments and senior teams supporting recruitment to academic middle management posts and meeting the development needs of current middle managers.

description: Violations of the law of one price (LOP) appear to be more the rule than the exception in various markets.This paper models the interface between agricultural supply and processing to explain violations of the LOP due to a fixed cost component of changing buyers. The model is applied to the raw rubber market in the Jambi province in Indonesia and employs a unique dataset of spatially and temporally disaggregated data. Methods to test for and explain violations of the LOP are suggested. An emphasis is set on the implications of aggregation over time.
