description: We present the discovery of seven X-ray emitting groups of galaxies selected as extended X-ray sources in the 200 ksec Chandra coverage of the All-wavelength Extended Groth Strip International Survey (AEGIS). In addition, we report on AGN activity associated to these systems. Using the DEEP2 Galaxy Redshift Survey coverage, we identify optical counterparts and determine velocity dispersions. In particular, we find three massive high-redshift groups at z>0.7, one of which is at z=1.13, the first X-ray detections of spectroscopically selected DEEP2 groups. We also present a first look at the the L_X-T, L_X-sigma, and sigma-T scaling relations for high-redshift massive groups. We find that the properties of these X-ray selected systems agree well with the scaling relations of similar systems at low redshift, although there are X-ray undetected groups in the DEEP2 catalogue with similar velocity dispersions. The other three X-ray groups with identified redshifts are associated with lower mass groups at z~0.07 and together form part of a large structure or "supergroup" in the southern portion of the AEGIS field. All of the low-redshift systems are centred on massive elliptical galaxies, and all of the high-redshift groups have likely central galaxies or galaxy pairs. All of the central group galaxies host X-ray point sources, radio sources, and/or show optical AGN emission. Particularly interesting examples of central AGN activity include a bent-double radio source plus X-ray point source at the center of a group at z=0.74, extended radio and double X-ray point sources associated to the central galaxy in the lowest-redshift group at z=0.066, and a bright green valley galaxy (part of a pair) in the z=1.13 group which shows optical AGN emission lines.

description: ”Vidensbydel Nørre Campus” er en af Europas største koncentrationer af uddannelse, grundforskning og anvendt forskning inden for bl.a. sundhedsvidenskab og naturvidenskab. I disse år foretager Københavns Kommune, Region Hovedstaden og Staten historiske store investeringer i området, herunder bl.a. udvidelser af Rigshospitalet og Panuminstituttet. Udviklingen af området kræver høj tilgængelighed til og fra området. Vidensbydelen skal bindes sammen med det øvrige København, men også med Øresundsregionen og det øvrige Europa. For at sikre en god tilgængelighed til området, let adgang til DTU i Lyngby, samt forbedre den kollektive trafik til og fra København for de mange pendlere, har Københavns Kommune med støtte fra Trafik- og Byggestyrelsen etableret en BRT-lignende busløsning på strækningen fra Emdrupvej v. Ryparken Station til Nørreport Station, kaldet ”Den Kvikke Vej”. Den kvikke vej stod færdig i efteråret 2014. Målet for projektet er at få flere til at tage bussen gennem et styrket kollektivt tilbud med bus til og fra Nørre Campus. Området ligger nemlig i en trafikkorridor med langt til både S-tog, regionaltog og metro (se figur 1). Samtidigt er der et begrænset udbud af p-pladser. Projektet har forbedret forholdene for buspassagerer uden at være til gene for bilister og cyklister.

description: We describe the theoretical advances that influenced the experimental creation of vibrationally and translationally cold polar $^{40}$K$^{87}$Rb molecules \cite{nphys08,science08}. Cold molecules were created from very-weakly bound molecules formed by magnetic field sweeps near a Feshbach resonance in collisions of ultra-cold $^{40}$K and $^{87}$Rb atoms. Our analysis include the multi-channel bound-state calculations of the hyperfine and Zeeman mixed X$^1Σ^+$ and a$^3Σ^+$ vibrational levels. We find excellent agreement with the hyperfine structure observed in experimental data. In addition, we studied the spin-orbit mixing in the intermediate state of the Raman transition. This allowed us to investigate its effect on the vibrationally-averaged transition dipole moment to the lowest ro-vibrational level of the X$^1Σ^+$ state. Finally, we obtained an estimate of the polarizability of the initial and final ro-vibrational states of the Raman transition near frequencies relevant for optical trapping of the molecules.

description: No abstracts are to be cited without prior reference to the author. Climate warming has been linked to an apparent general decrease in body sizes of ectotherms, both across and within taxa, especially in aquatic systems. We tested the hypothesis that diatoms are smaller at warmer temperatures using a system of geothermally heated streams in Iceland. To do this we examined both community and species levels of organization simultaneously, and developed a statistical method that calculates the proportion of size differences between communities that are due to intraspecific and interspecific effects. We found that there was no consistent relationship between size and temperature at either the population or community level. Therefore, these data provide important counterexamples to both James’ and Bergmann's temperature–size rules, respectively, undermining the widely held assumption that warming favours the small. In addition, we show that interspecific effects were a bigger contributor to whole-community size differences, and are probably more ecologically important than more commonly studied intraspecific effects. These findings highlight the need for multispecies approaches in future studies of climate warming and body size.
An understanding of how aviation is handled in Helsinki and Finland

name: Lassen, Claus
Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 2016

description: In conventional aviation research, airport development is often illustrated as ’closed’ and interlinked by transport systems that facilitate passenger transport; airlines provide the capacity in airspace, while airports provide the capacity for airlines and passengers on the ground. However in this article, we examine the driving forces behind the increase in the number of passengers through a social aeromobility approach and using a case study of Helsinki airport, drawing on stakeholders’ interviews. The main argument of the article is that the development of the airport network in Finland is a consequence of social processes and discussions involving multiple stakeholders with different local and global perspectives, where aviation policy is related to the narrative: ‘Finland is an island’. Further, we argue that such a narrative helps stimulate a political awareness of aviation, and this motivates the acceptance of large investments in infrastructure. In conclusion, the article therefore also puts forward the view that aviation development theoretically must be understood as more than a ‘global flow of machines in the aviation system’, and that the relationship between places and flying needs to be brought much more to the fore in future aeromobility research.

description: No abstracts are to be cited without prior reference to the author. Heterotrophic bacterioplankton are major players in organic matter cycling in the oceans. In spite of their high abundances and fast growth rates in surface waters, which make them suitable sentinels of global change, past analyses have largely overlooked this functional group. A time-series analysis of a decade of monthly observations in the upper mixed layer of the Southern Bay of Biscay continental shelf revealed strong seasonal patterns in the abundance, size and biomass of the universal groups of low (LNA) and high nucleic acid content (HNA) bacteria as distinguished by flow cytometry. Over this relatively short period we also found that bacterioplankton are already responding to the hypothesized temperature-driven decrease in body size. In particular, the variability of LNA bacteria was strongly coherent with ecological theories linking temperature, abundance and individual size. Concurrent with rising temperatures, significant interannual trends of increasing standing stocks (3% year-1 ) accompanied by decreasing mean cell size (-1% year-1 ) suggest a major shift in community structure, with a larger contribution of LNA cells to total biomass. Similarly to reports from other regions, LNA cells were likely dominated by members of the SAR11 clade at our site. We hypothesize that the increasing prevalence of these typically oligotrophic taxa may severely impact marine food webs and carbon fluxes in the future.
On delta modulation.
Creators: name: Greig, DJ
Publisher: name: University Of Tasmania
Year: 2023

description: The purpose of this thesis is to introduce Delta Modulation as an alternative to the more conventional carrier and pulse modulations, Chapter I briefly discusses the carrier and pulse modulations from the standpoint of signal - to - noise ratio, bandwidth occupancy and threshold effects. In this way, the merits of each is brought to the fore and the superiority of FM and PCM can he seen. Chapter II introduces Delta Modulation, a pulse code modulation, giving an extensive review of much of the more prominent literature on the subject. Aspects such as channel capacity, power, spectral densities, overloading, signal - to - noise ratio and bandwidth, are discussed. In Chapter III an experimental Delta-Sigma Modulation System is described in detail, from design to performance. Observations are made which correspond to some made in theory. The system transmits static signals and AC signals up to 20 HZ. The accuracy is good and the circuits simple. In Chapter IV suggestions are made to improve the systemis performance by simple means. Also mentioned are more elaborate means (Continuous Delta Modulation) which enhance the performance considerably but detract from the simplicity. Much of the literature quoted in the bibliography shows and discusses how delta modulation is simple in circuitry yet has all the advantages of PCM. It is upon this theme that the prototype Delta-Sigma Modulator is designed and built. All the circuits are kept as simple as possible. With integrated circuits, delta modulation is fast becoming an economical proposition. Delta modulation, though simple to implement, requires greater bandwidth than the conventional carrier modulations and PCM (for the same performance). At times this would make Delta Modulation uneconomical. However, there is a place for Delta Modulation alongside FM and PCM for some particular applications.
Effektundersøgelse af busfremkommelighed

Year: 2016

description: Effektundersøgelsen har til formål at afdække de samfundsøkonomiske effekter af forskellige typer busfremkommelighedsprojekter og omfatter fem konkrete projekter, som er etableret inden for de sidste fem år: • Aalborg BRT: Busvej i eget tracé over en strækning på ca. 2 km • Sluseholmen: Optimeret placering af busbane samt nyt gatingsignal • Toftegårds Allé: Busbane og signalprioritering • Flintholm Station: Ombygning af busterminal ved station samt busfremkommelighedstiltag i 9 kryds omkring stationen • Linje 202A i Roskilde: Signalprioritering og nyt gatingsignal De fem projekter varierer i omfang og virkemidler. De har det til fælles, at de er anlagt på strækninger med meget høje buspassagertal, og for alle fem projekter er det lykkedes at reducere bussens rejsetid. Samtidig er alle fem projekter etableret på strækninger med høje biltrafiktal. I nogle tilfælde har projekterne medført en rejsetidsgevinst for både bus- og biltrafik, og i andre er busfremkommeligheden opnået på bekostning af biltrafikken. Alle fem projekter er yderst rentable og har en intern rente, der ligger mellem 8% og 105%, hvilket er på niveau med andre typer infrastrukturprojekter, der er vedtaget eller udført inden for de seneste år. På baggrund af effektundersøgelsen anbefales det, at der ved fremtidige busfremkommelighedsprojekter er særligt fokus på følgende fire emner: • Fokus på strækninger eller områder med mange passagerer • Sikre tilstrækkelig kapacitet • Afvejning af hensyn til bustrafik og hensyn til biltrafik • Indsatser i større netværk eller på hele busruter med særligt fokus på at minimere flaskehalse

description: Umiddelbart før jul blev rejsekortsystemet endeligt afleveret fra leverandøren. Dermed er 10 års udviklingsarbejde afsluttet. Trafikselskaberne i Danmark, der sammen ejer rejsekortet, har derfor lagt en ny strategi for Rejsekort A/S, hvor rejsekortet skal være en nem billet til den kollektive transport. Rejsekortet skal være nemt at bruge, have faldende omkostninger – og dermed blive trafikselskabernes foretrukne billetmedie. På kort sigt skal driften af rejsekortet gøres mere effektivt for både passagerer og trafikselskaber, og rejsekortet skal integreres i trafikselskabernes digitale løsninger. På længere sigt skal kortet udvikles med nye funktioner og anvendelsesområder.

description: Kommunal forvaltning har historisk set været meget decentral, men tværgående koordinering og kapacitetsstyring bliver mere og mere relevant i moderne kommunal drift. Optimering af køretøjer og deres anvendelse er således under lup, når der både skal effektiviseres i udnyttelse og antal, samt konverteres til alternative drivmidler. I Københavns Kommune har politikerne derfor vedtaget som led i en ambitiøs klimaplan, at der skal implementeres GPS-baseret fleet management i den samlede vognpark. Projektet har en lidt særlig karakter, idet det både har organisatoriske og teknologiske implikationer for den sædvanlige kommunale drift. Det er et nyt IT-redskab, der giver anledning til nye procedurer. Indledningsvist alene til centralt overblik og rådgivning.

description: No abstracts are to be cited without prior reference to the author. The harvest of the introduced and now commercially valuable red king crab (Paralithodes camtschaticus) in northern Norway has a fishery history going back to 1994. The fishery management has undergone several changes, harvest rate being very low and increasing to very high in the recent 5-10 years. A male-only fishery went on for the first 14 years and since 2008 an additional small quota on female crabs has been given, with the same minimum legal size for both sexes. In this study we investigate effects of increasing harvest rate on the maximum size of both male and female crabs and discuss possible ecological consequences. Varangerfjorden was chosen as a main study area since this is the area of longest fishery history in Norwegian waters, and has been through all stages of the management of the crab fishery. Both the mature male and the ovigerous female part of the stock displayed a reduced maximum size around 1999-2000. A new and significant reduction in maximum size occurs in accordance with the onset of a fishery quota on females in 2008. Recently maximum body size for both male and female crabs seems to have stabilized and adjusted in accordance with the present harvest rate.

description: No abstracts are to be cited without prior reference to the author. Marine heterotrophic bacteria play key roles in carbon and nutrient cycling and as unicells and ectotherms are directly affected by temperature. One of the predicted effects of global warming is size reduction, with the subsequent consequences on biomass and turnover rates in the future ocean. To study this effect, we carried out monthly experiments during a complete annual cycle, incubating surface water (from 12.7 to 21.2 ºC) at three different temperature treatments (in situ, -3 ºC, +3 ºC). We followed the growth, standing stocks and biovolume changes of two widespread physiological groups detected by flow cytometry: high nucleic acid (HNA) and low nucleic acid (LNA) bacteria. The annual cycle showed that these groups have opposite seasonal trends, where smaller but more abundant abundant bacteria correspond to HNA cells in the colder spring and to LNA cells in the warmer summer. Surprisingly, the effect of temperature treatment on size was noticeable only upon the typically more active HNA bacteria, that showed a decrease in mean biovolume in 75% of experiments. The final effect on biomass was not significant in both cases, indicating that abundance has a greater effect than size for bacteria.

Universal hydrodynamics of non-conformal branes

Year: 2009
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We examine the hydrodynamic limit of non-conformal branes using the recently developed precise holographic dictionary. We first streamline the discussion of holography for backgrounds that asymptote locally to non-conformal brane solutions by showing that all such solutions can be obtained from higher dimensional asymptotically locally AdS solutions by suitable dimensional reduction and continuation in the dimension. As a consequence, many holographic results for such backgrounds follow from the corresponding results of the Asymptotically AdS case. In particular, the hydrodynamics of non-conformal branes is fully determined in terms of conformal hydrodynamics. Using previous results on the latter we predict the form of the non-conformal hydrodynamic stress tensor to second order in derivatives. Furthermore we show that the ratio between bulk and shear viscosity is fixed by the generalized conformal structure to be ζ/η= 2(1/(d-1) - c_s^2), where c_s is the speed of sound in the fluid.

Nye trends inden for persontransport services
Creators: name: Nielsen, Søren Saugstrup

Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 2016

description: Gennem de seneste år er privatbiler og den kollektive trafik blevet udfordret af en række nye tjenester, som fx GoMore og DriveNow, der tilbyder alternative former for persontransport ved hjælp af internettet og apps. Det kan være vanskeligt at spå om, hvordan nye internetbaserede persontransport services vil udvikle sig, hvordan de vil blive en del af vores hverdag, hvordan de kan påvirke vores transportvaner og den fysiske afvikling af trafikken i vores samfund som helhed. Dilemmaet kan opstå, hvis brugen af disse services vokse meget hurtigt og påvirker kapaciteten i den fysiske vejinfrastruktur. Det tager nemlig tid at udvide kapaciteten i den fysiske vejinfrastruktur, samtidig med at kapaciteten på vejnettet særligt i og omkring de store byer allerede i dag er udfordret. For Vejdirektoratet, der har vejbestyrelsesansvar for Statsvejnettet, er det vigtigt løbende at undersøge og forholde sig til trends og drivkræfter, der potentielt kan påvirke statsvejnettet og dets udvikling, herunder særligt kapaciteten på vejnettet. I en tematisk trendanalyse gennemført i 2015 har MOE|Tetraplan i samarbejde med Vejdirektoratet undersøgt nye persontransport services, hvor følgende er søgt besvaret: • Hvilke nye services findes allerede nu, og hvilke kan der forventes at komme til i nær fremtid? • Hvilken effekt på trafikken og dets afvikling ses i dag fra disse services, reducerer de trafikken eller øger de den? • Hvordan påvirker disse services danskernes transportvaner og evt. den fysiske afvikling af trafikken og kapaciteten på vejnettet? • Hvordan påvirkes kapaciteten, hvis services benyttes i myldretiden, eller hvis de i høj grad anvendes i geografiske områder, hvor strækninger og kryds er belastede i forvejen. • Hvilke effekter forventes persontransport services at få på trafikken på statsvejnettet på kort, mellem langt og lang sigt? I trendanalysen er en række internetbaserede persontransport services analyseret for at vurdere deres effekter på trafik og kapacitet på statsvejnettet. Analysen er af kvalitativ karakter, baseret på desktop research og den beskriver effekterne på overordnet niveau. For at forstå disse services og konsekvenserne af deres effekter bedre er konklusionen umiddelbart, at det er nødvendigt at gå længere ned i materien, og her er spørgsmålet, hvad er den rigtige tilgang?

description: Desire and Reason: about some neuroethical Issues
Many neuroscientific experiments have tried to investigate the possible correlation between our brain activity and the processes underlying our moral decision- making. By analyzing the experiments conducted by Joshua D. Greene, Benjamin Libet, Chun Siong Soon, the paper addresses the limits of a scientific and objectifying approach. Although the perspective of investigation in the third-person is definitely important, this approach is not comprehensive because it merely photographs emotional (and cognitive) activity of the subject, focusing on a single moment of his/her life. In this way, however, it fails to consider the practical identity of the subject, which is gradually built up over time, and continues to build and to redefine itself in the present and in the outlook of the future. This practical identity should be investigated in the first-person perspective, considering not only the singular actions, but the individual’s plan of life. By referring to some Aristotelian distinctions, the paper argues the intimate relationship existing between desire and reason. By addressing this relationship between desire and reason, which is typical of the human nature, the normative theory of Greene (dual-process theory) is criticized. Moreover, with respect to Libet and Soon’s experiments, it is argued that our freedom is not without determinations. Indeed, freedom deals with our actions, of which we are responsible; we perform these actions on the basis of specific reasons, that are relevant for us. Therefore it is impossible to understand what freedom properly is, regardless of these reasons.

description: We show how hydrogenation of graphene nanoribbons at small concentrations can open new venues towards carbon-based spintronics applications regardless of any especific edge termination or passivation of the nanoribbons. Density functional theory calculations show that an adsorbed H atom induces a spin density on the surrounding $π$ orbitals whose symmetry and degree of localization depends on the distance to the edges of the nanoribbon. As expected for graphene-based systems, these induced magnetic moments interact ferromagnetically or antiferromagnetically depending on the relative adsorption graphene sublattice, but the magnitude of the interactions are found to strongly vary with the position of the H atoms relative to the edges. We also calculate, with the help of the Hubbard model, the transport properties of hydrogenated armchair semiconducting graphene nanoribbons in the diluted regime and show how the exchange coupling between H atoms can be exploited in the design of novel magnetoresistive devices.

description: Internationalisering, globalisering og øget international samhandel er alle forhold, som har betydning for udviklingen i vognmandserhvervet og for udvikling i og sammensætning af den lastbiltrafikken på det danske vejnet. Den internationale lastbiltrafik er steget mere end den nationale lastbiltrafik, og andelen af udenlandske lastbiler på det danske vejnet er steget og fortsat stigende. Internationaliseringen betyder også, at opgaven med at indsamle statistik om og belyse udviklingen lastbiltrafikken er blevet mere kompleks, og at en valid statistik i stigende grad skal etableres på grundlag af flere forskellige datakilder. Formålet med paperet er med baggrund i forskellige statistiske kilder at give et overblik overudviklingen i lastbiltrafikken i Danmark særligt med fokus på den internationale del. Udgangspunktet har været at sammenstille de statistiske kilder. Det er videre et formål at afdække evt. forskel mellem de alternative statistiske kilder, og med baggrund heri af belyse evt. usikkerheder i statistikkerne, samt ikke mindst at kvalificere den samlede statistik om transport og trafikarbejdet gennemført med lastbil i Danmark.

Flat-Spectrum Radio Quasars from SDSS DR3 Quasar Catalogue

description: We constructed a sample of 185 Flat Spectrum Radio Quasars (FSRQs) by cross-correlating the Shen et al.'s SDSS DR3 X-ray quasar sample with FIRST and GB6 radio catalogues. From the spectrum energy distribution (SED) constructed using multi-band (radio, UV, optical, Infrared and X-ray) data, we derived the synchrotron peak frequency and peak luminosity. The black hole mass and the broad line region (BLR) luminosity (then the bolometric luminosity) were obtained by measuring the line-width and strength of broad emission lines from SDSS spectra. We define a subsample of 118 FSRQs, of which the nonthermal jet emission is thought to be dominated over the thermal emission from accretion disk and host galaxy. For this subsample, we found 25 FSRQs having synchrotron peak frequency > 10^{15} Hz, which is higher than the typical value for FSRQs. While only a weak anti-correlation is found between the synchrotron peak frequency and peak luminosity, it becomes significant when combining with the Wu et al.'s sample of 170 BL Lac objects. At similar peak frequency, the peak luminosity of FSRQs with $\nupeak > 10^{15}$ Hz is systematically higher than that of BL Lac objects, with some FSRQs out of the range covered by BL Lac objects. Although high $\nupeak$ are found in some FSRQs, they do not reach the extreme value of BL Lacs. For the subsample of 118 FSRQs, we found significant correlations between the peak luminosity and black hole mass, the Eddington ratio, and the BLR luminosity, indicating that the jet physics may be tightly related with the accretion process.

description: No abstracts are to be cited without prior reference to the author. Theoretical studies, long-term surveys and experimental data predict a reduction in body size across taxa under the current warming context. However, this rule might not be ubiquitous. Here we present time series analyses of the biogeochemical and phytoplankton trends that occurred in station E2 off A Coruña (NE Atlantic) since the late 1980s. Upwelling strength and sea surface temperature remained stable during the last decades. However, while nitrate fertilization showed a slight increase, phosphate concentration has strongly risen leading to a negative trend in N:P. Phytoplankton abundance responded differently to these shifts, with dinoflagellates showing an increase in abundance. Quantile regression indicated a negative relationship between species exhibiting decreasing trends in abundance and cell size. A heterogeneous model was also apparent for the relationship between size and species being less susceptible to changes in both N:P and upwelling strength. By contrast, larger species tended to show positive changes with temperature. These results suggest that cell size is a limiting factor given that larger cells were hardly ever associated with species-specific increases in abundance with time, changes in N:P or upwelling. However, other factors would be responsible of the different responses to temperature changes though not interacting with size.

description: Using two- and three-dimensional hydromagnetic simulations for a range of different flows, including laminar and turbulent ones, it is shown that solutions expressing the field in terms of Euler potentials (EP) are in general incorrect if the EP are evolved with an artificial diffusion term. In three dimensions, standard methods using the magnetic vector potential are found to permit dynamo action when the EP give decaying solutions. With an imposed field, the EP method yields excessive power at small scales. This effect is more exaggerated in the dynamic case, suggesting an unrealistically reduced feedback from the Lorentz force. The EP approach agrees with standard methods only at early times when magnetic diffusivity did not have time to act. It is demonstrated that the usage of EP with even a small artificial magnetic diffusivity does not converge to a proper solution of hydromagnetic turbulence. The source of this disagreement is not connected with magnetic helicity or the three-dimensionality of the magnetic field, but is simply due to the fact that the nonlinear representation of the magnetic field in terms of EP that depend on the same coordinates is incompatible with the linear diffusion operator in the induction equation.

description: We demonstrate the capability of continuous variable Gaussian states to communicate multipartite quantum information. A quantum teamwork protocol is presented according to which an arbitrary possibly entangled multimode state can be faithfully teleported between two teams each comprising many cooperative users. We prove that N-mode Gaussian weighted graph states exist for arbitrary N, that enable unconditional quantum teamwork implementations for any arrangement of the teams. These perfect continuous variable maximally multipartite entangled resources are typical among pure Gaussian states and are unaffected by the entanglement frustration occurring in multiqubit states.
