description: JWST has detected many overmassive galactic systems at $z > 4$, where the mass of the black hole, $M_\bullet$, is $10-100$ times larger than expected from local relations, given the host's stellar mass, $M_\star$. This Letter presents a model to describe these overmassive systems in the high-$z$ Universe. We suggest that the black hole mass is the main driver of high-$z$ star formation quenching. SMBHs globally impact their high-$z$ galaxies because their hosts are physically small, and the black holes have duty cycles close to unity at $z > 4$. In this regime, we assume that black hole mass growth is regulated by the quasar's output, while stellar mass growth is quenched by it and uncorrelated to the global properties of the host halo. We find that the ratio $M_\bullet/M_\star$ controls the average star formation efficiency: if $M_\bullet/M_\star > 8\times 10^{18} (n Λ/f_{edd})[(Ω_b M_h)/(Ω_m M_\star) - 1]$, then the galaxy is unable to form stars efficiently. Once this ratio exceeds the threshold, a runaway process brings the originally overmassive system towards the local $M_\bullet - M_\star$ relation. Furthermore, the $M_\bullet - M_\star$ relation evolves with redshift as $\propto (1+z)^{5/2}$. At $z \sim 5$, we find an overmassive factor of $\sim 55$, in excellent agreement with current JWST data and the high-$z$ relation inferred from those. Extending the black hole horizon farther in redshift and lower in mass will test this model and improve our understanding of the early co-evolution of black holes and galaxies.

description: In recent breakthrough experiments, twisted moiré layers of transition metal dichalcogenides are found to manifest both integer (IQAHE) and fractional (FQAHE) quantum anomalous Hall effects in zero applied magnetic field because of the underlying flat band topology and spontaneous breaking of the time reversal invariance. In the current work, we critically analyze the experimental values of the quantized conductance in each case to emphasize the role of disorder in the problem, pointing out that obtaining accurate quantized conductance in future experiments would necessitate better contacts and lower disorder.

Insights from the world’s first Mobility-as-a-Service (MaaS) system

description: As the world continues to urbanize — and more people attempt to navigate within and between cities and their peripheries — so too continues the development of more efficient modes of transportation, new niches of transport modes and services, and a more intuitive integration of modes to simplify the trip-making process for users. Perhaps most notably, changes are happening in the field of transportation due to the rapid application of technology. What has been a growing “menu” of discrete mobility options offered mostly by public agencies is now becoming a “spectrum” of mobility options; the differences between individual modes are blurring and mobility services are provided by a more complex mix of public and private operators. The most relevant combinations are now finding their way to the user based on their priorities, making mobility effortless and intuitive. This, ultimately, is the aim of Mobility-as-a-Service (MaaS), and the focus of this report.

description: D. 29. september 2019 får København og Frederiksberg en helt ny metro – Cityringen – der åbner med 17 nye stop gennem nogle af de tættest befolkede og mest besøgte områder. Den nye metro vil give et kæmpe løft til den offentlige transport i København og Frederiksberg, gøre det meget lettere at komme rundt i hovedstaden og passagererne vil opleve markante besparelser i rejsetiden. Metroen bygges naturligvis til at dække områder, hvor rigtig mange mennesker dagligt benytter den kollektive trafik. Disse områder er i forvejen tungt betjent af busser, og der er derfor behov for en omlægning af busnettet, så det sikres, at busserne supplerer og ikke dublerer den nye metro. Arbejdet med omlægningen af busnettet har siden 2014 været forankret i projekt ”Nyt Bynet”, og indebærer store ændringer på mange af de største og vigtigste buslinjer i København og Frederiksberg.

description: Cityringens åbning 29. september 2019 og den deraf følgende tilpasning af busnettet (Nyt Bynet) medførte store ændringer, som krævede at de eksisterende kontrakter blev tilpasses i form af tillægsaftaler. Movias kontraktafdeling fandt ikke, at den hidtil anvendte proces for forhandling af tillægsaftaler var egnet, hvorfor en ny proces så dagens lys. Den nye proces gav i højere grad end tidligere mulighed for at tage højde for operatørspecifikke forhold. Resultatet var i alt 3 tillægsaftaler, som håndterede f.eks. fordeling af linjer efter åbningen af Nyt Bynet. Der har i hele forløbet, både før, under og efter været fokus på åbenhed, ligebehandling og gennemsigtighed og ikke mindst inddragelse af operatørerne. Der har efter Movias opfattelse været tale om en succesfuld proces.

Trængsel på vejene - hvad koster det samfundet?

Year: 2019

description: Trængsel er et stigende problem i byerne og på indfaldsvejene. Trængsel er dyrt for samfundet og tidstabet i trafikken til gene for den enkelte bilist. I dette projekt har Vejdirektoratet analyseret det samfundsøkonomiske tab ved trængsel baseret på 2016 data. I projektet benyttedes en tidligere opbygget metode fra COWI, som opgjorde trængslen i 2010. Dermed kan vi sammenligne trængslen i dag med tidligere. Udregningerne er lavet på baggrund af rejsetider fra GPS-data, samt trafiktal fra Landstrafikmodellen. Vejdirektoratet har opgjort trængslen på vejene i 2016. På en gennemsnitlig hverdag i 2016 var der således en forsinkelse på omkring 335.000 køretøjstimer. Når forsinkelsestimerne på et hverdagsdøgn omregnes til årsbasis, bliver det til ca. 77 millioner tabte køretøjstimer. Tabet af timer kan på årsbasis omregnes til ca. 60.000 fuldtidsstillinger. Omregnes forsinkelsestimerne til samfundsøkonomi, var der i 2016 et samfundsøkonomisk tab på 24 mia. kr. pga. trængsel. Når der sammenlignes med den seneste officielle opgørelse, COWI’s opgørelse for trængslen i Hovedstadsområdet i 2010 for Transportministeriet, er forsinkelsen steget med i størrelsesordenen 25 pct. Stigningen i forsinkelsestimer har været over dobbelt så stor som stigningen i trafikken, der i samme periode er steget med 10 pct. i Region Hovedstaden.

Små motoriserede køretøjer – mobilitet på bekostning af sikkerhed?
Creators: name: Sørensen, Michael W. J.
Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 2019

description: Fra januar 2019 er det som en forsøgsordning blevet lovligt at benytte forskellige små motoriserede køretøjer som elektriske løbehjul, skateboards, segboard/hoverboard og uniwheels i offentlig trafik i Danmark. Tilsvarende ordninger ses også i mange andre lande og byer. Mange er begejstret for disse ordninger og mener det kan forbedre mobiliteten i byerne. Meget taler imidlertid for, at dette vil få negative trafiksikkerhedsmæssige konsekvenser, og flere organisationer og fagmiljøer har påpeget dette, bl.a. i hørringsvar til lovforslaget. Formålet med denne artikel har været at drøfte og uddybe de potentielle sikkerhedsmæssige aspekter ved denne ordning og komme med forslag til tiltag, som kan forbedre sikkerheden. Artiklen er baseret på en systematisk litteraturgennemgang af udenlandske studier og erfaringer, samt en systematisering af hvad danske og udenlandske fageksperter har sagt og skrevet om mulige sikkerhedsmæssige effekter. Gennemgangen giver et relativt entydigt billede af, at disse små køretøjer med stor sandsynlighed vil give forringet trafiksikkerhed i byområderne. Amerikanske studier tyder på, at de største sikkerhedsproblemer er eneulykker i form af fald/vælteulykker eller påkørsel af objekter. Manglende hjelmbrug og sandsynligvis kørsel under påvirket tilstand udgør også store problemer. I denne artikel fokuseres der på de sikkerhedsmæssige effekter, men disse køretøjer har potentiel også andre og mere positive effekter i forhold til mobilitet, miljø og klima. Det centrale spørgsmål er derfor ikke nødvendigvis, om disse igen skal forbydes eller ej, men mere hvordan man skal sikre, at man ikke får den frygtede stigning i trafikulykker. Det er derfor beskrevet en række tiltag rettet mod fører, køretøj og infrastruktur, som kan medvirke til at reducere ulykkesrisikoen. De vigtigste er; lovpligtig hjelmbrug, oplæring, information og kontrol, intelligent fartstilpasning, justering af køretøjernes indretning så brugen bliver mere intuitiv samt justering af infrastrukturen i form af især bredere cykelstier og bedre drift og vedligeholdelse.

Il s’intéresse également à comment celle-ci est enseignée sur le lieu de formation et interroge l’efficacité des dispositifs prévus pour la développer. Nous avons mené une recherche qualitative pour sonder les significations qu’attribuent certains étudiants interrogés à la pratique réflexive et le rôle des dispositifs des modules d’intégration de la HEP Vaud dans leur élaboration. Après un état des lieux de la littérature scientifique relative au sujet, nous avons choisi de mener dix entretiens auprès de sept étudiants BP de deuxième et troisième année ainsi que trois enseignantes novices venant d’achever leur cursus. Cet échantillon nous a offert une hétérogénéité et confère également une certaine pertinence à notre recherche puisque les étudiants questionnés sont suffisamment familiers avec les questions relatives à la pratique réflexive. Lors des dix entretiens semi-directifs que nous avons menés, les participants à notre recherche ont été invités à partager leur vécu ainsi que leurs perceptions de la pratique réflexive. Ces échanges se sont révélés riches. Ils ont témoigné d’une pluralité de significations attribuées à cette pratique, mais aussi de multiples usages. Nous traitons également l’influence que le rapport à l’écriture de chaque étudiant peut avoir sur la mise en oeuvre de cette pratique et sur son développement au sein de la formation. Nous avons également questionné notre échantillon quant aux dispositifs mis en oeuvre à la HEP Vaud afin de guider les étudiants dans le développement de cette compétence clé de la profession. Notre recherche peut présenter certaines pistes de compréhension aux formateurs de la HEP Vaud, mais aussi aux étudiants qui sont dans le cursus ou à toute personne s’intéressant à la pratique réflexive et au développement de l’identité professionnelle.

description: GaAs(111)B is a semiconductor substrate widely used in research and commercial fields due to its low cost, mature synthesis technology, and excellent properties for manufacturing electronic devices. It is not only used to grow three-dimensional (3D) strongly-bonded materials, but has also been used as a substrate for layered, van der Waals (vdW)-bonded chalcogenide film growth. However, GaAs(111)B wafers cannot be directly used for growing epitaxial vdW chalcogenide films for two reasons: (1) the GaAs surface has a substantial number of dangling bonds that need to be passivated for vdW layers growth; (2) the substrate surface is covered with a thin epi-ready oxide layer which must be removed before film growth. In this paper, we optimize the method for deoxidizing GaAs(111)B substrates under a Se overpressure and successfully create a smooth, deoxidized, and passivated substrate for subsequent growth of vdW chalcogenide materials. We demonstrate the benefits of this method for the growth of vdW chalcogenide thin films using GaSe as a representative of vdW chalcogenides. In addition, we find that severely aged substrates have difficulty maintaining a smooth surface during the deoxidation and passivation process and cause GaSe crystals to nucleate in random shapes and orientations. We describe a method using water droplet testing to determine the age of the substrate. Finally, X-ray photoelectron spectroscopy (XPS) characterization reveals that the natural aging of GaAs(111)B in the air results in an increase in surface oxides, Ga2O3 and As2O3, while exposure to ultraviolet (UV)-ozone not only enhances the contents of these two oxides but also generates a new oxide, As2O5. Our research contributes to expanding the compatibility of GaAs(111)B with diverse growth materials and the production of high-quality heterostructure devices.

description: Irradiation cis-[M(Ln-S,O)2] complexes (M = PtII, PdII) derived from N,N-dialkyl-N′-benzoylthioureas (HLn) with various sources of intense visible polychromatic or monochromatic light with λ < 500 nm leads to light-induced cis → trans isomerization in organic solvents. In all cases, white light derived from several sources or monochromatic blue-violet laser 405 nm light, efficiently results in substantial amounts of the trans isomer appearing in solution, as shown by 1H NMR and/or reversed-phase HPLC separation in dilute solutions at room temperature. The extent and relative rates of cis/trans isomerization induced by in situ laser light (λ = 405 nm) of cis-[Pd(L2-S,O)2] was directly monitored by 1H NMR and 195Pt NMR spectroscopy of selected cis-[Pt(L-S,O)2] compounds in chloroform-d; both with and without light irradiation allows the δ(195Pt) chemical shifts cis/trans isomer pairs to be recorded. The cis/trans isomers appear to be in a photo-thermal equilibrium between the thermodynamically favored cis isomer and its trans counterpart. In the dark, the trans isomer reverts back to the cis complex in what is probably a thermal process. The light-induced cis/trans process is the key to preparing and isolating the rare trans complexes which cannot be prepared by conventional synthesis as confirmed by the first example of trans-[Pd(L-S,O)2] characterized by single-crystal X-ray diffraction, deliberately prepared after photo-induced isomerization in acetonitrile solution.
En ny måde at styre på. Den gradvise institutionalisering af statsgarantimodellen i dansk transportinfrastrukturstyring.
Creators: name: Christensen, Lene Tolstrup
Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 2019

description: Artiklen analyserer, hvordan og hvorfor den danske statsgarantimodel (SGM) er blevet institutionaliseret i den danske transportinfrastruktur som en ny styringsform og hvilke styringsudfordringer, der opstår herved. Artiklen bygger på et teoretisk perspektiv om offentlig styring og gradvis forandring i et historisk institutionelt perspektiv og er baseret på et komparativt casestudie af de syv danske transportinfrastrukturprojekter, der anvender SGM. Artiklens argument er, at institutionaliseringen af SGM går fra, at modellen udvikles som en løsning for at realisere et enkelt projekt til et nyt institutionelt lag som selvstændig styringsmodel i en aflejringsproces. Dette nye lag leder til en udskiftningsproces, der udfordrer den etablerede styringsform: styrelsesmodellen. I denne proces konverteres de oprindelige projektvirksomheder til mere overordnede moderne statslige selskaber, der bliver stadigt mere indlejret i den overordnede infrastrukturstyring i styrelsesmodellen via deres ekspertise og finansiering af det eksisterende netværk. Det gør, at styrelsesmodellen bliver udfordret i forhold til den dominerende politik om gratis og offentligt finansieret infrastruktur. SGM er således en ny måde at organisere og styre offentlig infrastruktur på, men som artiklen viser, er styringsformen baseret på individuelle projekter og praksis samt en lav grad af formalisering i form af en overordnet styringsramme for anvendelse af modellen i en situation, hvor modellen bliver stadig mere sammensat, kompleks og samtidigt mere udbredt.

description: Characterization of structural diversity within soft materials is key for engineering new materials for various applications. Small-angle scattering (SAS) is a widely used characterization technique that provides structural information in soft materials at varying length scales and typically outputs scattered intensity I(q) as a function of the scattered wavevector represented by its magnitude q and azimuthal angle θ. While isotropic structures can be interpreted from azimuthally averaged 1D SAS profile, to understand anisotropic spatial arrangements, one has to interpret the 2D SAS profile, I(q,θ). In this paper, we present a new method called CREASE-2D that interprets I(q,θ) as is and outputs the relevant structural features. CREASE-2D is an extension of the 'computational reverse engineering analysis for scatting experiments' (CREASE) method that has been used successfully to analyze 1D SAS profiles for a variety of soft materials. CREASE uses a genetic algorithm for optimization and a surrogate machine learning (ML) model for fast calculation of 1D 'computed' scattering profiles that are then compared to the experimental 1D scattering profiles during optimization. In CREASE-2D, which goes beyond CREASE in interpretting 2D scattering profiles, we use XGBoost as the surrogate ML model to relate structural features to the I(q,θ) profile. The CREASE-2D workflow identifies the structural features whose computed I(q,θ) profiles match the input experimental I(q,θ). We test the performance of CREASE-2D by using as input a variety of in silico 2D SAS profiles with known structural features and demonstrate that CREASE-2D converges towards their correct structural features. We expect this method will be valuable for materials' researchers who need direct interpretation of 2D scattering profiles to explore structural anisotropy.

description: Anvendelse af håndholdt mobiltelefon under cykling er forbudt ved lov i Danmark, imens det på tidspunktet for nærværende undersøgelse endnu var lovligt i Nederlandene. Gennem kvalitative interviews med cyklister i Danmark (n=9) og Nederlandene (n=10) undersøges cyklisters motiver, ræsonnementer og adfærd i forhold til brug af håndholdt og håndfri mobiltelefon under cykling. Herigennem identificeres specifikke anvendelsesformål og motivationer for at anvende og undlade at bruge mobiltelefon under cykling. Analysen viser at lovgivningen har indvirkning på nogle af deltagernes rationaler og risikoforståelse. Endvidere viser undersøgelsen, at det er relevant at se på både psykologiske og eksterne faktorer, for at forstå hvorfor cyklister anvender deres telefon i trafikken.

Five hexanuclear clusters, [Mn6O2(sao)6(HOsal)2(EtOH)4]·EtOH (1·EtOH), [Mn6O2(sao)6{1,8-naph(CO2Me)(CO2)}2(MeOH)6]·3MeOH (2·3MeOH), [Mn6O2(naphthsao)6{1,8-naph(CO2Et)(CO2)}2(EtOH)6] (3·2MeOH), [Mn6O2(naphthsao)6(MeCO2)2(EtOH)4]·2H2O (4·2H2O), and [Mn6O2(naphthsao)6{(HO)2PhCO2}2(EtOH)4]·4EtOH (5·4EtOH), have been synthesized and characterized by single-crystal X-ray crystallography. The magnetic properties of 3, 4, and 5 are discussed.

description: I rigtig mange kommuner bliver der gjort meget for at øge antallet af cyklister. Men nogle gange kommer vi måske til at sætte trafiksikkerheden over styr for at få flere til at cykle? I Københavns kommune havde vi i 2018 tre dødsulykker, hvor en ligeudkørende cyklist blev kørt ned af en højresvingende lastbil. I folkemunde kaldet ”en højresvingsulykke” og teknisk en ”312-ulykke” Hver ulykke er en for meget og i København har Borgerrepræsentationen vedtaget en Vision om, at ingen må blive dræbt eller komme alvorligt til skade i trafikken. Særligt dødsulykkerne er der stort fokus på, og vi vil derfor gøre alt for at undgå at ulykkerne sker. Desværre er det meget sjældent, at en ulykke sker samme sted, som der tidligere er sket ulykker. Vi har derfor undersøgt, om vi ud fra hvor der sker mindre alvorlige 312-ulykker med cyklister, kan ”forudsige” hvor risikoen for de alvorligste ulykker er størst. Det viser sig, at vi ikke direkte ud fra hvor der sker mange ulykker kan forudsige, hvor der er risiko ”for den næste” højresvings-døds-ulykke sker. Måske overvejende fordi antallet af dødsulykker – alt andet lige - er meget lille. Men der viste sig noget andet interessant….

description: Irradiation cis-[M(Ln-S,O)2] complexes (M = PtII, PdII) derived from N,N-dialkyl-N’-benzoylthioureas (HLn) with various sources of intense visible polychromatic or monochromatic light with λ < 500 nm leads to light-induced cis → trans isomerization in organic solvents. In all cases, white-light derived from several sources or monochromatic blue-violet laser 405 nm light, efficiently results in substantial amounts of the trans-isomer appearing in solution, as shown by 1H NMR and/or reversed-phase HPLC separation in dilute solutions at room temperature. The extent and relative rates of cis/trans isomerization induced by in situ laser light (λ = 405 nm) of cis-[Pd(L2-S,O)2] was directly monitored by 1H NMR and 195Pt NMR spectroscopy of selected cis-[Pt(L-S,O)2] compounds in chloroform-d, both with and without light irradiation allows the δ(195Pt) chemical shifts cis/trans isomer pairs to be recorded. The cis/trans isomers appear to be in a photo-thermal equilibrium between the thermodynamically favored cis-isomer and its trans counterpart. In the dark the trans-isomer reverts back to the cis-complex in what is probably a thermal process. The light-induced cis/trans process is the key to preparing and isolating the rare trans-complexes which cannot be prepared by conventional synthesis as confirmed by the first example of trans-[Pd(L-S,O)2] characterized by single crystal X-ray diffraction, deliberately prepared after photo-induced isomerization in acetonitrile solution.

Fact-checking of timetabling principles: a case study on the relationship between planned headways and delays
Creators: name: Cerreto, Fabrizio

Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 2019

description: The tradeoff between reliability and level of service is a central focus for railway operators and infrastructure managers. A well-performing timetable must include an optimal level of buffer time between conflicting train movements, such that a high service delivery and a high service quality are maintained. This focus on buffer time has informed the research within the fields of timetable optimization, capacity utilization and delay propagation modeling. Despite recent and ongoing advancements in these fields, there are still disconnects between the theoretical models and their application in the design, planning and evaluation of railway timetabling. Parameters that are used in timetabling, as well as, as input to the analytical assessment models, are typically derived from practical experience and based on the macroscopic limitations of a system, rather than the microscopic conflicts inherent in its signaling system. The objective of this paper is to support the design of fact-based timetables by introducing a method of applying statistical analysis of the relationship between planned headways and recorded delays to estimate the minimum feasible headway between conflicting train movements in a railway system. This method is applied on the busiest railway line in Denmark and the results from recorded operations are validated through microsimulation.

description: We investigate the impacts of an imaginary transverse field on the dynamics of magnetic domain walls in a quantum Ising chain. We show that an imaginary field plays a similar role as a real transverse field in forming a low-lying Wannier-Stark ladder. However, analytical and numerical calculations of the time evolutions in both systems show that the corresponding Bloch oscillations exhibit totally different patterns for the same initial states. These findings reveal the nontrivial effect of non-Hermiticity on quantum spin dynamics.
