description: We study the link between baryons and dark matter in 240 galaxies with spatially resolved kinematic data. Our sample spans 9 dex in stellar mass and includes all morphological types. We consider (i) 153 late-type galaxies (LTGs; spirals and irregulars) with gas rotation curves from the SPARC database; (ii) 25 early-type galaxies (ETGs; ellipticals and lenticulars) with stellar and HI data from ATLAS^3D or X-ray data from Chandra; and (iii) 62 dwarf spheroidals (dSphs) with individual-star spectroscopy. We find that LTGs, ETGs, and "classical" dSphs follow the same radial acceleration relation: the observed acceleration (gobs) correlates with that expected from the distribution of baryons (gbar) over 4 dex. The relation coincides with the 1:1 line (no dark matter) at high accelerations but systematically deviates from unity below a critical scale of ~10^-10 m/s^2. The observed scatter is remarkably small (<0.13 dex) and largely driven by observational uncertainties. The residuals do not correlate with any global or local galaxy property (baryonic mass, gas fraction, radius, etc.). The radial acceleration relation is tantamount to a Natural Law: when the baryonic contribution is measured, the rotation curve follows, and vice versa. Including ultrafaint dSphs, the relation may extend by another 2 dex and possibly flatten at gbar<10^-12 m/s^2, but these data are significantly more uncertain. The radial acceleration relation subsumes and generalizes several well-known dynamical properties of galaxies, like the Tully-Fisher and Faber-Jackson relations, the "baryon-halo" conspiracies, and Renzo's rule.

description: We derive formulas for the classical Chern-Simons invariant of irreducible $SU(n)$-flat connections on negatively curved locally symmetric three-manifolds. We determine the condition for which the theory remains consistent (with basic physical principles). We show that a connection between holomorphic values of Selberg-type functions at point zero, associated with R-torsion of the flat bundle, and twisted Dirac operators acting on negatively curved manifolds, can be interpreted by means of the Chern-Simons invariant. On the basis of Labastida-Marino-Ooguri-Vafa conjecture we analyze a representation of the Chern-Simons quantum partition function (as a generating series of quantum group invariants) in the form of an infinite product weighted by S-functions and Selberg-type functions. We consider the case of links and a knot and use the Rogers approach to discover certain symmetry and modular form identities.

description: By analyzing the dissipative dynamics of a tunable gap flux qubit, we extract both sides of its two-sided environmental flux noise spectral density over a range of frequencies around $2k_BT/h \approx 1\,\rm{GHz}$, allowing for the observation of a classical-quantum crossover. Below the crossover point, the symmetric noise component follows a $1/f$ power law that matches the magnitude of the $1/f$ noise near $1\,{\rm{Hz}}$. The antisymmetric component displays a 1/T dependence below $100\,\rm{mK}$, providing dynamical evidence for a paramagnetic environment. Extrapolating the two-sided spectrum predicts the linewidth and reorganization energy of incoherent resonant tunneling between flux qubit wells.

Determinants of Infrastructure Project Delays and Cost Escalations: The Cases of Road and Railway Construction Projects in Ethiopia
Creators: name: Yenealem, Fentahun

Year: 2018

description: Construction of road and rail projects to enhance social and economic activities of the country. The number of road and rail construction projects in the country increasing time to time. These construction projects achieve or failure of objectives measured by whether successfully completed on time and cost or not. However, most of federal road and rail construction projects in the country exposed to time and cost overruns. It becomes difficult to complete projects on schedule and allocated budget. To fill the gap, the study on causes of time and cost overrun was conducted. Questionnaire surveys together with project completion report were used. A total of 73 questionnaires from owner, consultants and contractors were collected and secondary data of 30 (25 roads and 5 rails) construction projects completed since 2014 in federal road and rail agencies were investigated. From the analysis it was found that 88% of road and 100% rail construction projects suffered time performance, and 80% of road and 100% of rail projects also cost overruns. The key time and cost overrun determinants ranked by respondents conducted through questionnaire and interview managers and engineers who have experience of delay construction projects from clients, contractors and consultants in purposive sampling method. From these identified and ranked 38 determinants five top extension of time and 4 escalation of cost are selected for discussion. Factors which affected time performance were: incomplete study prior to project approval, poor project management and coordination, right of way issues, inaccurate forecasting of schedule, overconfidence and interest of project stakeholders. Whereas the extremely significant factors affecting cost performance were; inflation of material cost, scope change with change order, incomplete study project approval, poor bill of quantity and design, and poor project performance monitoring. Cost and time overruns of Federal road and rail projects have affected key stakeholders in particularly and on the economy of the country generally. Time and cost overrun added in estimated time and cost over and above initial agreed upon on set, this damages client and contractor reputation, loss of profit and investment opportunities, inability to deliver value of money and inefficient use of time, disposing business activities and create burden for taxpayers. This paper finally came up with solutions towards reducing the impact of delays and cost overruns on federal road and rail projects in Ethiopia.

description: We deduce the intrinsic conductivity properties of the ferroelectric domain walls around the topologically protected domain vortex cores in multiferroic YMnO3. This is achieved by performing a careful equivalent-circuit analysis of dielectric spectra measured in single-crystalline samples with different vortex densities. The conductivity contrast between the bulk domains and the less conducting domain boundaries is revealed to reach up to a factor 500 at room temperature, depending on sample preparation. Tunneling of localized defect charge carriers is the dominant charge-transport process in the domain walls that are depleted of mo-bile charge carriers. This work demonstrates that via equivalent-circuit analysis, dielectric spectroscopy can provide valuable information on the intrinsic charge-transport properties of ferroelectric domain walls, which is of high relevance for the design of new domain-wall-based microelectronic devices.

Measuring neutron star tidal deformability with Advanced LIGO: a Bayesian analysis of neutron star - black hole binary observations

description: The discovery of gravitational waves (GW) by Advanced LIGO has ushered us into an era of observational GW astrophysics. Compact binaries remain the primary target sources for LIGO, of which neutron star-black hole (NSBH) binaries form an important subset. GWs from NSBH sources carry signatures of (a) the tidal distortion of the neutron star by its companion black hole during inspiral, and (b) its potential tidal disruption near merger. In this paper, we present a Bayesian study of the measurability of neutron star tidal deformability $Λ_\mathrm{NS}\propto (R/M)^{5}$ using observation(s) of inspiral-merger GW signals from disruptive NSBH coalescences, taking into account the crucial effect of black hole spins. First, we find that if non-tidal templates are used to estimate source parameters for an NSBH signal, the bias introduced in the estimation of non-tidal physical parameters will only be significant for loud signals with signal-to-noise ratios $> 30$. For similarly loud signals, we also find that we can begin to put interesting constraints on $Λ_\mathrm{NS}$ (factor of 1-2) with individual observations. Next, we study how a population of realistic NSBH detections will improve our measurement of neutron star tidal deformability. For astrophysical populations of $disruptive$ NSBH mergers, we find 20-35 events to be sufficient to constrain $Λ_\mathrm{NS}$ within $\pm 25-50\%$, depending on the chosen equation of state. In this we also assume that LIGO will detect black holes with masses within the astrophysical $mass$-$gap$. If the mass-gap remains preserved in NSBHs detected by LIGO, we estimate that $25\%$ $additional$ detections will furnish comparable tidal measurement accuracy. In both cases, we find that the loudest 5-10 events to provide most of the tidal information, thereby facilitating targeted follow-ups of NSBHs in the upcoming LIGO-Virgo runs.

description: We study the problem of determining optimal coordinated motions for two disc robots in an otherwise obstacle-free plane. Using the total path length traced by the two disc centres as a measure of distance, we give an exact characterization of a shortest collision-avoiding motion for all initial and final configurations of the robots. The individual paths are composed of at most six (straight or circular-arc) segments, and their total length can be expressed as a simple integral with a closed form solution depending only on the initial and final configuration of the robots. Furthermore, the paths can be parametrized in such a way that (i) only one robot is moving at any given time (decoupled motion), or (ii) the angle between the two robots' centres changes monotonically.

description: Although $SO(10)$ Supersymmetric (SUSY) Grand Unification Theories (GUTs) are very attractive for neutrino mass and mixing, it is often quite difficult to achieve successful leptogenesis from the lightest right-handed neutrino $N_1$ due to the strong relations between neutrino and up-type quark Yukawa couplings. We show that in a realistic model these constraints are relaxed, making $N_1$ leptogenesis viable. To illustrate this, we calculate the baryon asymmetry of the Universe $ Y_B $ from flavoured $ N_1 $ leptogenesis in a recently proposed $ Δ(27) \times SO(10) $ SUSY GUT. The flavoured Boltzmann equations are solved numerically, and comparison with the observed $ Y_B $ places constraints on the allowed values of right-handed neutrino masses and neutrino Yukawa couplings. The flavoured $SO(10)$ SUSY GUT is not only fairly complete and predictive in the lepton sector, but can also explain the BAU through leptogenesis with natural values in the lepton sector albeit with some tuning in the quark sector.

description: We consider black hole solutions of Einstein gravity that describe deformations of CFTs at finite temperature in which spatial translations have been broken explicitly. We focus on deformations that are periodic in the non-compact spatial directions, which effectively corresponds to considering the CFT on a spatial torus with a non-trivial metric. We apply a DC thermal gradient and show that in a hydrodynamic limit the linearised, local thermal currents can be determined by solving linearised, forced Navier-Stokes equations for an incompressible fluid on the torus. We also show how sub-leading corrections to the thermal current can be calculated as well as showing how the full stress tensor response that is generated by the DC source can be obtained. We also compare our results with the fluid-gravity approach.

description: Domain adaptive detection aims to improve the generality of a detector, learned from the labeled source domain, on the unlabeled target domain. In this work, drawing inspiration from the concept of stability from the control theory that a robust system requires to remain consistent both externally and internally regardless of disturbances, we propose a novel framework that achieves unsupervised domain adaptive detection through stability analysis. In specific, we treat discrepancies between images and regions from different domains as disturbances, and introduce a novel simple but effective Network Stability Analysis (NSA) framework that considers various disturbances for domain adaptation. Particularly, we explore three types of perturbations including heavy and light image-level disturbances and instancelevel disturbance. For each type, NSA performs external consistency analysis on the outputs from raw and perturbed images and/or internal consistency analysis on their features, using teacher-student models. By integrating NSA into Faster R-CNN, we immediately achieve state-of-the-art results. In particular, we set a new record of 52.7% mAP on Cityscapes-to-FoggyCityscapes, showing the potential of NSA for domain adaptive detection. It is worth noticing, our NSA is designed for general purpose, and thus applicable to one-stage detection model (e.g., FCOS) besides the adopted one, as shown by experiments. https://github.com/tiankongzhang/NSA.

description: We study a multi-component dark matter model where interactions with the Standard Model are primarily via the Higgs boson. The model contains vector-like fermions charged under $SU(2)_W \times U(1)_Y$ and under the dark gauge group, $U(1)^\prime$. This results in two dark matter candidates. A spin-1 and a spin-1/2 candidate, which have loop and tree-level couplings to the Higgs, respectively. We explore the resulting effect on the dark matter relic abundance, while also evaluating constraints on the Higgs invisible width and from direct detection experiments. Generally, we find that this model is highly constrained when the fermionic candidate is the predominant fraction of the dark matter relic abundance.

description: We demonstrate the optical initialization of a hole-spin qubit bound to an isoelectronic center (IC) formed by a pair of Te impurities in ZnSe, an impurity/host system providing high optical homogeneity, large electric dipole moments, and long coherence times. The initialization scheme is based on the spin-preserving tunneling of a resonantly excited donor-bound exciton to a positively charged Te IC, thus forming a positive trion. The radiative decay of the trion within less than 50 ps leaves a heavy hole in a well-defined polarization-controlled spin state. The initialization fidelity exceeds 98:5 % for an initialization time of less than 150 ps.

description: In recent years, nanoporous thin films have been widely studied for thermoelectric applications. High thermoelectric performance is reported for nanoporous Si films, which is attributed to the dramatically reduced lattice thermal conductivity and bulk-like electrical properties. Porous materials can also be used in gas sensing applications by engineering the surface-trapped charges on pore edges. In this work, an analytical model is developed to explore the relationship between the thermoelectric properties and pore-edge charges in a periodic two-dimensional nanoporous material. The presented model can be widely used to analyze the measured electrical properties of general nanoporous thin films and two-dimensional materials.

description: Electron-phonon coupling directly determines the stability of cooperative order in solids, including superconductivity, charge and spin density waves. Therefore, the ability to enhance or reduce electron-phonon coupling by optical driving may open up new possibilities to steer materials' functionalities, potentially at high speeds. Here we explore the response of bilayer graphene to dynamical modulation of the lattice, achieved by driving optically-active in-plane bond stretching vibrations with femtosecond mid-infrared pulses. The driven state is studied by two different ultrafast spectroscopic techniques. Firstly, TeraHertz time-domain spectroscopy reveals that the Drude scattering rate decreases upon driving. Secondly, the relaxation rate of hot quasi-particles, as measured by time- and angle-resolved photoemission spectroscopy, increases. These two independent observations are quantitatively consistent with one another and can be explained by a transient three-fold enhancement of the electron-phonon coupling constant. The findings reported here provide useful perspective for related experiments, which reported the enhancement of superconductivity in alkali-doped fullerites when a similar phonon mode was driven.

Year: 2010

description: This study is launched with the purpose to explore the effort made by ERCA to achieve the goals of BPR. BPR is a radical rethinking of an organization and it is cross functional, end- to-end process and an effective tool of work design. The researcher preferred to undertake the study in examining the current situation in reference to the desired set of conditions as per the theoretical framework of BPR. By so doing, points of investigation pertaining to the challenges and prospects are helpful for policy makers, policy implementers and policy beneficiaries. Attempts have been made to investigate the compelling factors initiated ERCA to introduce BPR to its system, challenges facing in implementation process and prospects envisioned including indicative achievements in relation with BPR. Data was gathered through Questionnaire, Interview and Review of both published and unpublished materials. A total of 121 persons were contacted for the study, i.e. 84 employees and middle level managers from Headquarters, 2 Directors, 1 Deputy Director General from ERCA,30 top management members from the six branches of ERCA around Addis Ababa, 3 representatives from the three selected customer associations and 1 consultant from CSRP office of MCB. The findings of the study, among other things, revealed that BPR has been considered as the causal factor for effectiveness and efficiency as well as better customers service; the degree of commitment of top management is fairly high; the awareness and the attitude of employees as well as the management is moderate which is accompanied by significant commitment gap and resistance to change; weak IT infrastructure; and weak evaluation and monitoring. To alleviate the challenges it is recommended that implementation of the new laws, rules, regulations, manuals etc, should be preceded by an appropriate training and awareness development. In addition to this, the decision making process need to be participative and transparent

description: A novel specific spin-labeling strategy for bioactive molecules is presented for eptifibatide (integrilin) an antiplatelet aggregation inhibitor, which derives from the venom of certain rattlesnakes. By specifically labeling the disulfide bridge this molecule becomes accessible for analytical techniques such as Electron Paramagnetic Resonance (EPR) and solid state Dynamic Nuclear Polarization (DNP). The necessary spin-label was synthesized and inserted into the disulfide bridge of eptifibatide via reductive followed by insertion by a double Michael addition under physiological conditions. This procedure is universally applicable for disulfide containing biomolecules and is expected to preserve their tertiary structure with minimal change due to the small size of the label and restoring of the previous disulfide connection. HPLC and MS analysis show the successful introduction of the spin label and EPR spectroscopy confirms its activity. DNP-enhanced solid state NMR experiments show signal enhancement factors of up to 19 in ¹³C CP MAS experiments which corresponds to time saving factors of up to 361. This clearly shows the high potential of our new spin labeling strategy for the introduction of site selective radical spin labels into biomolecules and biosolids without compromising its conformational integrity for structural investigations employing solid-state DNP or advanced EPR techniques.

Data show significant unmet demand for Shariah-compliant financial services, particularly among micro-small and medium-sized enterprises (MSMEs). To fill this financing gap, Shariah-compliant products offered to MSMEs are mostly leasing and asset resale arrangements, with very little application of profit and loss sharing contracts. This paper employs a qualitative research method to look at the role of Islamic finance in unlocking the potential of MSMEs. In addition, the emergence of Financial Technology (Fintech) has given the Islamic financial system an impetus to compete on an equal footing with the conventional system and prove itself. This study will examine the role of Islamic finance in recovery post-COVID-19 and how Fintech can be utilized to combat the economic repercussions that resulted from COVID-19. In addition to other existing articles, this paper suggests that combining the principles of Islamic finance, the advancements in technology, and Fintech represents an opportunity to significantly contribute to the enhancement of the entrepreneurial ecosystem in the Islamic world and the promotion of MSMEs segment development. This paper proposes using modern technology to unlock the potential of Islamic finance in contributing to entrepreneurship and MSME development. The findings of this study have significant implications for policymakers and governments, notably guidance on how to apply FinTech and effectively promote innovative Islamic financial services.

description: We study weak convergence of empirical processes of dependent data, indexed by classes of functions. We obtain results that are especially suitable for data arising from dynamical systems and Markov chains, where the Central Limit Theorem for partial sums is commonly derived via the spectral gap technique. Our results apply, e.g. to the empirical process of ergodic torus automorphisms.

description: Existing work on Counterfactual Explanations (CE) and Algorithmic Recourse (AR) has largely focused on single individuals in a static environment: given some estimated model, the goal is to find valid counterfactuals for an individual instance that fulfill various desiderata. The ability of such counterfactuals to handle dynamics like data and model drift remains a largely unexplored research challenge. There has also been surprisingly little work on the related question of how the actual implementation of recourse by one individual may affect other individuals. Through this work, we aim to close that gap. We first show that many of the existing methodologies can be collectively described by a generalized framework. We then argue that the existing framework does not account for a hidden external cost of recourse, that only reveals itself when studying the endogenous dynamics of recourse at the group level. Through simulation experiments involving various state-of the-art counterfactual generators and several benchmark datasets, we generate large numbers of counterfactuals and study the resulting domain and model shifts. We find that the induced shifts are substantial enough to likely impede the applicability of Algorithmic Recourse in some situations. Fortunately, we find various strategies to mitigate these concerns. Our simulation framework for studying recourse dynamics is fast and opensourced.

description: Field-effect phototransistors were fabricated based on individual carbon nanotubes (CNTs) sensitized by CH$_3$NH$_3$PbI$_3$ nanowires (MAPbI$_3$NW). These devices represent light responsivities of R=7.7x10$^5$ A/W at low-lighting conditions in the nWmm$^{-2}$ range, unprecedented among CNT-based photo detectors. At high incident power (~1 mWmm$^{-2}$), light soaking results in a negative photocurrent, the device turns insulating. We interpret the phenomenon as a result of efficient electron-hole separation and charge transfer of holes from the perovskite to the carbon nanotube, which improves conductance by increasing the number of carriers, but leaves electrons behind. At high illumination intensity the random electrostatic potential of these quench the mobility in the nanotube. The single CNT device geometry allows the local study of the MAPbI$_3$NW/CNT interface for metallic and semiconducting CNTs separately. Infrared and Raman spectroscopy studies of CNT-CH$_3$NH$_3$PbI$_3$ composites revealed that photo-doping takes place at the interface.

description: Introduction et objectif. Depuis 2019, le séquençage du génome entier est réalisé en routine pour toutes les entérobactéries productrices de bêtalactamases à spectre élargi (EBLSE) isolées chez les patients hospitalisés en réanimation au centre hospitalier universitaire de Caen. Cette étude évalue un algorithme d’alerte simple afin de détecter les transmissions croisées et les épidémies. Matériel et méthodes. L’alerte de transmission croisée est basée sur l’identification de deux EBLSE de même espèce en réanimation adulte sur une période d’un mois glissant. Les performances de ces alertes étaient calculées pour trois espèces d’EBLSE (Klebsiella pneumoniae, Escherichia coli et Enterobacter cloacae complexe) en les comparant aux données issues du séquençage des souches isolées en 2019 et 2020 puis en prospectif en 2021. Résultats. L’algorithme a été créé à partir des 320 souches d’EBLSE identifiées et séquencées : 138 E. coli, 91 K. pneumoniae et 91 E. cloacae. Le taux global de transmission croisée était de 22% en 2019-2020 (respectivement 1,5%, 42% et 33% pour chaque espèce) et de 21,2% en 2021 (0%, 16,7% et 54,0%). La valeur prédictive positive de notre algorithme est de 14,3% pour E. coli, 92,7% pour K. pneumoniae et 51,8% pour E. cloacae. Conclusion. Par une approche génomique, nous pouvons détecter et alerter toute transmission croisée afin d’adapter les mesures de prévention ainsi que les enquêtes environnementales en cas d’épidémie. L’algorithme donne une orientation précoce des alertes mais peut et doit s’adapter selon les dynamiques de diffusion, qui semblent être différentes entre espèces.

description: We find the first smooth microstate geometries with non-Abelian fields. The solutions constitute an extension of the BPS three-charge smooth microstates. These consist in general families of regular supersymmetric solutions with non-trivial topology, i.e. bubbles, of $\mathcal{N}=1$, $d=5$ Super-Einstein-Yang-Mills theory, having the asymptotic charges of a black hole or black ring but with no horizon. The non-Abelian fields make their presence at the very heart of the microstate structure: the physical size of the bubbles is affected by the non-Abelian topological charge they carry, which combines with the Abelian flux threading the bubbles to hold them up. Interestingly the non-Abelian fields carry a set of adjustable continuous parameters that do not alter the asymptotics of the solutions but modify the local geometry. This feature can be used to obtain a classically infinite number of microstate solutions with the asymptotics of a single black hole or black ring.

description: This paper describes a semiclassical field-theory approach to the topological properties of spatially featureless Affleck-Kennedy-Lieb-Tasaki type valence bond solid ground states of antiferromagnets in spatial dimensions one to three. Using nonlinear sigma models set in the appropriate target manifold and augmented with topological terms, we argue that the path integral representation of the ground-state wave functional can correctly distinguish symmetry-protected topological ground states from topologically trivial ones. The symmetry-protection feature is demonstrated explicitly in terms of a dual field theory, where we take into account the nontrivial spatial structure of topological excitations, which are caused by competition among the relevant ordering tendencies. A temporal surface contribution to the action originating from the bulk topological term plays a central role in our study. We discuss how the same term governs the behavior of the so-called strange correlator. In particular, we find that the path integral expression for the strange correlator in two dimensions reduces to the well-known Haldane expression for the two point spin correlator of antiferromagnetic spin chains.
