description: Gravitational instabilities in a magnetized Friedman - Robertson - Walker (FRW) Universe, in which the magnetic field was assumed to be too weak to destroy the isotropy of the model, are known and have been studied in the past. Accordingly, it became evident that the external magnetic field disfavors the perturbations' growth, suppressing the corresponding rate by an amount proportional to its strength. However, the spatial isotropy of the FRW Universe is not compatible with the presence of large-scale magnetic fields. Therefore, in this article we use the general-relativistic (GR) version of the (linearized) perturbed magnetohydrodynamic equations with and without resistivity, to discuss a generalized Jeans criterion and the potential formation of density condensations within a class of homogeneous and anisotropically expanding, self-gravitating, magnetized fluids in curved space-time. We find that, for a wide variety of anisotropic cosmological models, gravito-magnetic instabilities can lead to sub-horizonal, magnetized condensations. In the non-resistive case, the power spectrum of the unstable cosmological perturbations suggests that most of the power is concentrated on large scales (small k), very close to the horizon. On the other hand, in a resistive medium, the critical wave-numbers so obtained, exhibit a delicate dependence on resistivity, resulting in the reduction of the corresponding Jeans lengths to smaller scales (well bellow the horizon) than the non-resistive ones, while increasing the range of cosmological models which admit such an instability.

description: Given a bipartite quantum state rho with subsystems A and B of arbitrary dimensions, we study the entanglement detecting capabilities of locally noneffective, or cyclic, unitary operations [L. B. Fu, Europhys. Lett., vol. 75, pp. 1-7, 2006]. Local cyclic unitaries have the special property that they leave their target subsystem invariant. We investigate the distance between rho and the global state after local application of such unitaries as a possible indicator of entanglement. To this end, we derive and discuss closed formulae for the maximal such distance achievable for three cases of interest: (pseudo)pure quantum states, Werner states, and two-qubit states. What makes this criterion interesting, as we show here, is that it surprisingly displays behavior similar to recent anomalies observed for non-locality measures in higher dimensions, as well as demonstrates an equivalence to the CHSH inequality for certain classes of two-qubit states. Yet, despite these similarities, the criterion is not itself a non-locality measure. We also consider entanglement detection in bound entangled states.

description: We present the results of an observational study of the efficiency of deep mixing in globular cluster red giants as a function of stellar metallicity. We determine [C/Fe] abundances based on low-resolution spectra taken with the Kast spectrograph on the 3m Shane telescope at Lick Observatory. Spectra centered on the 4300 Angstrom CH absorption band were taken for 42 bright red giants in 11 Galactic globular clusters ranging in metallicity from M92 ([Fe/H]=-2.29) to NGC 6712 ([Fe/H]=-1.01). Carbon abundances were derived by comparing values of the CH bandstrength index S2(CH) measured from the data with values measured from a large grid of SSG synthetic spectra. Present-day abundances are combined with theoretical calculations of the time since the onset of mixing, which is also a function of stellar metallicity, to calculate the carbon depletion rate across our metallicity range. We find that the carbon depletion rate is twice as high at a metallicity of [Fe/H]=-2.3 than at [Fe/H]=-1.3, which is a result qualitatively predicted by some theoretical explanations of the deep mixing process.

description: We consider the conditions for integrating out heavy chiral fields and moduli in N=1 supergravity, subject to two explicit requirements. First, the expectation values of the heavy fields should be unaffected by low energy phenomena. Second, the low energy effective action should be described by N=1 supergravity. This leads to a working definition of decoupling in N=1 supergravity that is different from the usual condition of gravitational strength couplings between sectors, and that is the relevant one for inflation with moduli stabilization, where some light fields (the inflaton) can have long excursions in field space. It is also important for finding de Sitter vacua in flux compactifications and KKLT scenarios, since failure of the decoupling condition invalidates the implicit assumption that the stabilization and uplifting potentials have a low energy supergravity description. We derive a sufficient condition for supersymmetric decoupling, namely, that the Kahler invariant function G = K + log |W|^2 is of the form G = L(light, (heavy)) with H and L arbitrary functions, which includes the particular case G = L(light) + H(heavy). The consistency condition does not hold in general for the ansatz K = K(light) + K(heavy), W = W(light) + W(heavy) and we discuss under what circumstances it does hold.

description: Policies significantly shape computation's societal impact, a crucial HCI concern. However, challenges persist when HCI professionals attempt to integrate policy into their work or affect policy outcomes. Prior research considered these challenges at the ``border'' of HCI and policy. This paper asks: What if HCI considers policy integral to its intellectual concerns, placing system-people-policy interaction not at the border but nearer the center of HCI research, practice, and education? What if HCI fosters a mosaic of methods and knowledge contributions that blend system, human, and policy expertise in various ways, just like HCI has done with blending system and human expertise? We present this re-imagined HCI-policy relationship as a provocation and highlight its usefulness: It spotlights previously overlooked system-people-policy interaction work in HCI. It unveils new opportunities for HCI's futuring, empirical, and design projects. It allows HCI to coordinate its diverse policy engagements, enhancing its collective impact on policy outcomes.

Electronic versus mechanical loading in the determination of peak oxygen consumption in bicycle ergometry

Publisher: name: University of British Columbia
Year: 2010

description: The purpose of the study was to determine if differences in the loading (or braking) systems of two different types of stationary bicycle ergometers (Monark and Dynavit models) influenced the performances of subjects in similar submaximal and maximal exercise. A maximal treadmill test, also performed by the subjects, was used as a criterion measure with which the maximal bicycle ergometer test results were compared. The possibility of finding differences in the performances of subjects on the two bicycle ergometers and of similarities between maximal bicycle and treadmill tests would appear to have important implications for laboratory and field testing procedures, as well as for costs of equipment used in physical fitness work and exercise physiology. Thirteen non-trained, college-aged male volunteers, 18 to 26 years, took part in the study. Each subject performed one test on each of three pieces of testing equipment; the Dynavit bicycle, the Monark bicycle, and the treadmill. Each test consisted of a maximal exercise bout of a continuous, incremental nature, during which time the appropriate physiological data was recorded. There was an interval of at least three days between tests, the subjects being assigned treatment orders via a Latin square design. Principal variables examined during maximal exercise were total work time and peak oxygen consumption; at submaximal exercise levels they were oxygen uptake and heart rate. Other variables examined, although not of central importance to the study, were maximal heart rate, maximal oxygen pulse, submaximal oxygen pulse, and subjective response to exercise. A Beckman Metabolic Measurement Cart, interfaced with a Hewlett-Packard Data Acquisition system, recorded the pertinent physiological data, which was then analyzed by the use of one and two-way ANOVA's and Newman-Keuls post hoc tests where appropriate. The results indicated no significant differences in total work time, peak oxygen consumption, maximal heart rate, maximal oxygen pulse, submaximal heart rate, submaximal oxygen uptake, submaximal oxygen pulse, and subjective response to exercise between the two bicycle ergometers. Only the treadmill elicited higher values of peak oxygen consumption than either of the cycle ergometers. This Tack of a significant difference suggests that although there may be structural differences in the loading (or braking) systems of the Dynavit and Monark ergometers, these differences are not reflected by the subjects' physiological responses to comparable levels of exercise intensity. Thus the results indicate that these bicycles could be used interchangeably for such predictive tests of physical work capacity as the Astrand-Ryhming Predicted Oxygen Uptake Test or the Modified Sjostrand PWC Test.

description: We consider a straightforward extension of the 4-dimensional spacetime $M_4$ to the space of extended events associated with strings/branes, corresponding to points, lines, areas, 3-volumes, and 4-volumes in $M_4$. All those objects can be elegantly represented by the Clifford numbers $X\equiv x^A γ_A \equiv x^{a_1 ...a_r} γ_{a_1 ...a_r}, r=0,1,2,3,4$. This leads to the concept of the so-called Clifford space ${\cal C}$, a 16-dimensional manifold whose tangent space at every point is the Clifford algebra ${\cal C \ell }(1,3)$. The latter space besides an algebra is also a vector space whose elements can be rotated into each other in two ways: (i) either by the action of the rotation matrices of SO(8,8) on the components $x^A$ or (ii) by the left and right action of the Clifford numbers $R=$exp$ [α^A \gam_A]$ and $S=$exp$ [β^A \gam_A]$ on $X$. In the latter case, one does not recover all possible rotations of the group SO(8,8). This discrepancy between the transformations (i) and (ii) suggests that one should replace the tangent space ${\cal C \ell}(1,3)$ with a vector space $V_{8,8}$ whose basis elements are generators of the Clifford algebra ${\cal C \ell}(8,8)$, which contains the Lie algebra of the exceptional group E$_8$ as a subspace. E$_8$ thus arises from the fact that, just as in the spacetime $M_4$ there are $r$-volumes generated by the tangent vectors of the spacetime, there are $R$-volumes, $R=0,1,2,3,...,16$, in the Clifford space ${\cal C}$, generated by the tangent vectors of ${\cal C}$.

Ein probates Mittel ist dabei der Rekurs auf den Charakter, der beim Gegner möglichst negativ, im eigenen Fall unbedingt positiv gezeichnet wird. Neben Verfehlungen im sittlich-moralischen Bereich wird gegen eine erkleckliche Anzahl von Amtsinhabern oft diffamierend der Vorwurf der aktiven und/oder passiven Bestechung erhoben, während im Hinblick auf die eigene Person die Redner bemüht sind, sich selbst als unbestechlich, redlich und einzig im Sinne der Polis agierende Person darzustellen. In welchen Bereichen des politischen Lebens die Gier des Menschen nach Mehr dazu führte, gegenüber unlauteren Mitteln generell und Bestechungsversuchen im Speziellen offen zu sein, wird anhand der attischen Gerichtsreden untersucht.

description: TOI-849b is one of the few planets populating the hot-Neptune desert and it is the densest Neptune-sized one discovered so far. Its extraordinary proximity to the host star, together with the absence of a massive H/He envelope on top of the $40.8 ~M_{\oplus}$ rocky core calls into question the role played by the host star in the evolution of the system. We aim to study the impact of the host star's rotational history on the evolution of TOI-849b, focussing on the planetary migration due to dynamical tides dissipated in the stellar convective envelope and on the high-energy emission. Rotating stellar models of TOI-849 are coupled to our orbital evolution code to study the evolution of the planetary orbit. The evolution of the planetary atmosphere is studied by means of the JADE code, which uses realistic XUV-fluxes provided by our rotating stellar models. Assuming that the planet was at its present day position ($a=0.01598 \rm AU$) at the protoplanetary disc dispersal, with mass $40.8~ M_{\oplus}$, and considering a broad range of host star initial surface rotation rates ($Ω_{\rm in}$) in the range $ [3.2, 18]~ Ω_{\odot}$, we find that only for $Ω_{\rm in} \leq 5 Ω_{\odot}$ do we reproduce the current position of the planet, given that for $Ω_{\rm in}$ larger than $5 Ω_{\odot}$ its orbit is efficiently deflected by dynamical tides. We tested the impact of increasing the initial mass of the planet on the efficiency of tides, finding that a higher initial mass ($1~M_{\rm Jup}$) does not change the results reported above. Based on these results we computed the evolution of the planetary atmospheres with the JADE code for a large range of initial masses above a core mass of $40.8~M_{\oplus}$, finding that the strong XUV-flux received by the planet is able to remove the entirety of the envelope within the first 50 Myr, even if it formed as a Jupiter-mass planet.

description: The significant momentum and importance of Mining Software Repositories (MSR) in Software Engineering (SE) has fostered new opportunities and challenges for extensive empirical research. However, MSR researchers seem to struggle to characterize the empirical methods they use into the existing empirical SE body of knowledge. This is especially the case of MSR experiments. To provide evidence on the special characteristics of MSR experiments and their differences with experiments traditionally acknowledged in SE so far, we elicited the hallmarks that differentiate an experiment from other types of empirical studies and characterized the hallmarks and types of experiments in MSR. We analyzed MSR literature obtained from a small-scale systematic mapping study to assess the use of the term experiment in MSR. We found that 19% of the papers claiming to be an experiment are indeed not an experiment at all but also observational studies, so they use the term in a misleading way. From the remaining 81% of the papers, only one of them refers to a genuine controlled experiment while the others stand for experiments with limited control. MSR researchers tend to overlook such limitations, compromising the interpretation of the results of their studies. We provide recommendations and insights to support the improvement of MSR experiments.
Religion und Kult als politische Faktoren im Peloponnesischen Krieg

description: In diesem Beitrag wird die Rolle von religiösen Phänomenen des klassischen Griechenlands auf die im Geschichtswerk des Thukydides geschilderten Ereignisse, welche Vorgeschichte und Verlauf des Peloponnesischen Krieges beschreiben, untersucht. Zunächst wird hierzu auf den Forschungsstand und die historiographische Methode des Thukydides, sofern sie für die Themenstellung relevant erscheint, dargelegt. Im Anschluss daran wird anhand zahlreicher Fallbeispiele aus dem Primärwerk, welche skizziert und interpretiert, sowie phänomenologisch gemäß den jeweils politisch zum Tragen kommenden kultisch-religiösen Aspekten typologisiert werden, die komplexe Wechselwirkung zwischen der politischen und religiösen Sphäre beleuchtet. Es zeigt sich hierbei, dass Religion und Kult teils mit bemerkenswertem Pragmatismus als politische „Stilmittel“ eingesetzt werden, teils aber auch dann politisch wirkmächtige Faktoren darstellen, wenn man den traditionell-religiösen Vorstellungen und Praktiken Folge leistet. Ferner reicht die Bandbreite von Begebenheiten, bei welchen religiöse Phänomene politisch wirksam werden, von räumlich wie personell sehr begrenzten Fällen bis hin zu zwischenstaatlichen Auseinandersetzungen größter Tragweite. Zudem lassen sich in Hinblick auf den Umgang mit Religion und Kult bei den hauptsächlichen Konfliktparteien des Peloponnesischen Krieges merkliche Unterschiede konstatieren. Die antike griechische Religion tritt also auch im thukydideischen Geschichtswerk als geradezu omnipräsentes Politikum zutage.

description: We examine a variety of observations that shed light on the orientation of the semi-major axis of the Eta Carinae massive binary system. Under several assumptions we study the following observations: The Doppler shifts of some He I P-Cygni lines that is attributed to the secondary's wind, of one Fe II line that is attributed to the primary's wind, and of the Paschen emission lines which are attributed to the shocked primary's wind, are computed in our model and compared with observations. We compute the hydrogen column density toward the binary system in our model, and find a good agreement with that deduced from X-ray observations. We calculate the ionization of surrounding gas blobs by the radiation of the hotter secondary star, and compare with observations of a highly excited [Ar III] narrow line. We find that all of these support an orientation where for most of the time the secondary - the hotter less massive star - is behind the primary star. The secondary comes closer to the observer only for a short time near periastron passage, in its highly eccentric (e~0.9) orbit. Further supporting arguments are also listed, followed by discussion of some open and complicated issues.

description: Particle accelerators are essential tools in science, hospitals and industry. Yet, their costs and large footprint, ranging in length from meters to several kilometres, limit their use. The recently demonstrated nanophotonics-based acceleration of charged particles can reduce the cost and size of these accelerators by orders of magnitude. In this approach, a carefully designed nano-structure transfers energy from laser light to the particles in a phase-synchronous manner, thereby accelerating them. However, so far, confinement of the particle beam in the structure over extended distance has been elusive; it requires complex control of the electron beam phase space and is mandatory to accelerate particles to the MeV range and beyond with minimal particle loss. Here, we demonstrate complex electron phase space control at optical frequencies in the 225 nanometre narrow channel of a record-long photonic nanostructure. In particular, we experimentally show alternating phase focusing, a particle propagation scheme for, in principle, arbitrarily long minimal-loss transport. We expect this work to enable MeV electron beam generation on a photonic chip, with direct ramification for new forms of radiotherapy and compact light sources, and other forms of electron phase space control resulting in narrow energy or zeptosecond-bunched beams, for instance.

description: Aufgrund der Notwendigkeit der regionalen Differenzierung bzgl. der sogenannten „Krise des 3. Jhs.“ im Römischen Reich wird die Krisenfrage für die Region Bithynien gestellt. Das geschieht am Beispiel der Stadt Nikaia und des Goteneinfalls von 258/9, wobei dessen Auswirkungen im Mittelpunkt stehen. Diese werden durch Einbeziehung von Vergleichen aus Pontus und Paphlagonien sowie Bithynien passierenden Heeren und der Münzprägung verdeutlicht. Es zeigt sich, dass sich Bithynien im dritten Viertel des 3. Jhs. nicht am Rande des Zusammenbruchs, aber dennoch in einer Krisensituation befand.

description: We describe a framework for gauge mediation of supersymmetry breaking in which the messengers are charged under the hidden sector gauge group but do not play a role in breaking supersymmetry. From this point of view, our framework is between ordinary gauge mediation and direct mediation. As an example, we consider the 3-2 model of dynamical supersymmetry breaking, and add to it massive messengers which are SU(2) doublets. We briefly discuss the phenomenology of this scenario.

The effects of fatigue on vigilance in sailing
Creators: name: Thomas, David William
Publisher: name: University of British Columbia
Year: 2010

description: The Effects of Fatigue on Vigilance in Sailing. Twelve male subjects were tested to determine if increasing amounts of physical fatigue are related to the attention paid to sail trim during sailing. A sailing simulator was used to determine if fatigue, either mental or physical, caused vigilance to vary while the subject was sitting on the side deck, hiking or hiking with weight. Each subject responded to 45 windshifts by adjusting the main sheet to provide proper sail trim for three separate sessions, each one being fifteen minutes long. Telltale deflection was videotaped to provide a vigilance score with deflection time starting when the telltales lifted and ending when adjustment of the sail stopped. Five fitness tests, number of sit-ups in one minute, percent body fat, isometric strength in the hiking position, isometric endurance in the hiking position and maximum oxygen uptake were administered on a separate day to determine if fitness scores were related to vigilance capacity. It was found that neither mental nor physical fatigue caused a decrease in vigilance over the fifteen minute test session. There was a learning effect associated with the apparatus as mean vigilance score for each successive sailing simulator session decreased regardless of the treatment used. Only one of the physical fitness tests was related to vigilance capacity as maximum oxygen uptake values were inversely correlated with mean vigilance scores. Subjects with high aerobic capacity were faster at responding to windshifts, thus supporting the use of a large aerobic component in dry land fitness programs.
Città come patroni? Due casi problematici dall’Iberia romana

description: The contribution focuses on two pieces of epigraphic evidence from Roman Spain, which suggest special example of municipal patronage: instead of a normal relationship patronus-clientes, the inscriptions mention a whole city as a patron of an individual belonging to another community. Il contributo si concentra su due iscrizioni dalla Spagna romana che sembrano delineare un rapporto del tutto particolare di patronato municipale, al cui interno un’intera città accoglie entro la propria clientela e fides un individuo appartenente ad un’altra comunità.

Multiple kinetic k-essence, phantom barrier crossing and stability

description: We investigate models of dark energy with purely kinetic multiple k-essence sources that allow for the crossing of the phantom divide line, without violating the conditions of stability. It is known that with more than one kinetic k-field one can possibly construct dark energy models whose equation of state parameter $\wx$ crosses -1 (the phantom barrier) at recent red-shifts, as indicated by the Supernova Ia and other observational probes. However, such models may suffer from cosmological instabilities, as the effective speed of propagation $\cx$ of the dark energy density perturbations may become {\it imaginary} while the $\wx = -1$ barrier is crossed. Working out the expression for $\cx$ we show that multiple kinetic k-essence fields do indeed lead to a $\wx = -1$ crossing dark energy model, satisfying the stability criterion $\cx^2 \geq 0$ as well as the condition $\cx \leq 1$ (in natural units), which implies that the dark energy is not super-luminal. As a specific example, we construct a phantom barrier crossing model involving three k-fields for which $\cx$ is a constant, lying between 0 and 1. The model fits well with the latest Supernova Ia Union data, and the best fit shows that $\wx$ crosses -1 at red-shift $z \sim 0.2$, whereas the dark energy density nearly tracks the matter density at higher red-shifts.

Reversable heat flow through the carbon nanotube junctions

description: Microscopic mechanisms of externally controlled reversable heat flow through the carbon nanotube junctions (NJ) are studied theoretically. Our model suggests that the heat is transfered along the tube section ${\cal T}$ by electrons ($e$) and holes ($h$) moving ballistically in either in parallel or in opposite directions and accelerated by the bias source-drain voltage $V_{\rm SD}$ (Peltier effect). We compute the Seebeck coefficient $α$, electric $σ$ and thermal $κ$ conductivities and find that their magnitudes strongly depend on $V_{\rm SD}$ and $V_{\rm G}$. The sign reversal of $α$ versus the sign of $V_{\rm G}$ formerly observed experimentally is interpreted in this work in terms of so-called chiral tunneling phenomena (Klein paradox).
Incolae libertini a Carthago nova: le associazioni di liberti e di persone trasferite a partire da CIL II 3419
Creators: name: Reali, Francesco
Publisher: name: Wiener Beiträge zur Alten Geschichte online (WBAGon)

description: The A. reconsiders the usual interpretation of CIL II 3419 from Carthago Nova, as it seems unlikely that a specific group of incolae libertini was mentioned along with the coloni. By considering other epigraphic evidence, some possibilities are discussed: libertini were a separated group which acted together with coloni and incolae as a local association of freedmen, or rather as an association of former slaves which stayed as consistentes and were neither coloni nor incolae; coloni et incolae libertini meant an association of freedmen who were either coloni or incolae. L’A. riconsidera l’interpretazione solitamente accettata di CIL II 3419 da Carthago Nova, poiché risulta improbabile che comparisse un gruppo di incolae libertini accanto a quello dei coloni. Attraverso il confronto con altro materiale epigrafico, si considerano le possibilità che quello dei libertini fosse un gruppo a parte che agiva insieme a coloni ed incolae in quanto associazione locale di liberti, o piuttosto un’associazione di liberti consistentes presso la città, senza essere né coloni né incolae; coloni et incolae libertini potrebbe indicare altrimenti un’associazione di liberti che erano coloni o incolae.

description: The first 52 fs of a time evolution of the electron density in OCS after an interaction with an intense sub 10 fs laser pulse are studied using the time-dependent density functional theory. The nuclear motion in this linear trimer is simulated by the classical molecular dynamics method. Laser fields of intensity 10^{13} W/cm^2 and 10^{15} W/cm^2 are used. Details of the laser induced changes of the structure, as well as the ionization rate are sensitive to the applied field intensity and its polarization. It is found that under suitable conditions the OCS molecule bends soon after an interaction with a laser pulse. A deviation from the linear geometry of up to 23.6^\circ and charged ions of up to +3 are observed. The time evolution of electric dipole moments and the time-dependent electron localization function (ELF) are also studied.
