description: Der Streit über den "richtigen" Weg prägte die Architektur in der Weimarer Zeit. Die Kontroverse war aber nicht nur ästhetisch begründet, sie spiegelte vielmehr die gesellschaftlichen Verwerfungen wider und mündete in der Stigmatisierung des Neuen Bauens. Die Untersuchung klärt, inwieweit und mit welcher Bestimmung institutionelle und prozessuale Einflüsse auf das Baugeschehen wirkten und ob diese abseits der aufgeschlossenen Metropolen die Ausbreitung einer modernen Formensprache verhinderten.

description: Quantum Computation and Quantum Information are continuously growing research areas which are based on nature and resources of quantum mechanics, as superposition and entanglement. In its gate array version, the use of convenient and appropriate gates is essential. But while those proposed gates adopt convenient forms for computational algorithms, in the practice, their design depends on specific quantum systems and stuff being used. Gates design is restricted to properties and limitations of interactions and physical elements being involved, where Quantum Control plays a deep role. Quantum complexity of multipartite systems and their interactions requires a tight control to manipulate their quantum states, either local and non-local ones, but still a reducibility procedure should be addressed. This work shows how a general $2d$-partite two level spin system in $SU(2d)$ could be decomposed in $2^{n-1}$ subsystems on $SU(2)$, letting establish control operations. In particular, it is shown that Bell gems basis is a set of natural states on which decomposition happen naturally under some interaction restrictions. Thus, alternating the direction of local interaction terms in the Hamiltonian, this procedure states a universal exchange semantics on those basis. The structure developed could be understood as a splitting of the $2d$ information channels into $2^{2d-1}$ pairs of $2$ level information subsystems.

description: We report on NuSTAR and Swift observations of a soft state of the neutron star low-mass X-ray binary GS 1826-24, commonly known as the "clocked" burster. The transition to the soft state was recorded in 2014 June through an increase of the 2-20 keV source intensity measured by MAXI, simultaneous with a decrease of the 15-50 keV intensity measured by Swift/BAT. The episode lasted approximately two months, after which the source returned to its usual hard state. We analyze the broad-band spectrum measured by Swift/XRT and NuSTAR, and estimate the accretion rate during the soft episode to be about 13% of Eddington, within the range of previous observations. However, the best fit spectral model, adopting the double Comptonization used previously, exhibits significantly softer components. We detect seven type-I X-ray bursts, all significantly weaker (and with shorter rise and decay times) than observed previously. The burst profiles and recurrence times vary significantly, ruling out the regular bursts that are typical for this source. One burst exhibited photospheric radius expansion, and we estimate the source distance at about (5.7 / xi_b^1/2) kpc, where xi_b parameterizes the possible anisotropy of the burst emission. Interpreting the soft state as a transition from an optically thin inner flow to an optically thick flow passing through a boundary layer, as is commonly observed in similar systems, is contradicted by the lower optical depth measured for the double Comptonization model we find for this soft state. The effect of a change in disk geometry on the burst behavior remains unclear.

description: In this paper we examine the meaning of conversing with pedagogical agents. Previous research has focused on examining cause and effect relationships, failing to take into account the meaning of the experiences individuals have when holding a dialogue with conversational agents for educational purposes. To understand these experiences, we have conducted a phenomenological examination of what it means to converse with a pedagogical agent. In phenomenological terms, findings suggest the experience is complex, engrossing, virtual yet real, human-like, and social. Implications for the future design, implementation, and research of conversational agents in educational and other settings are discussed.

description: Corporate Real Estate Corporate real estate is real estate that is necessary for an organization to conduct its business. CRE can be owned or leased space and is different than commercial real estate. CoreNet Global (2015) describes that in commercial real estate, real estate is core business, and the goal is to provide a risk adjusted return to the investor; whereas, in corporate real estate, real estate supports the business function. Corporate real estate represents the demand side or user side of real estate, while commercial real estate focuses on the supply side to meet that demand. CRE function lacks tools to deliver the most business impact Sharp (2013) concluded based on 636 survey responses that CRE teams face barriers to meet present challenges. The barriers are “C-suite resistance to capital expenditure; the sometimes small and fragmented structure of the CRE function; inadequate access to deep data and analytics to measure value; and a fundamental skill and knowledge gap within CRE teams ... . Furthermore, many CRE departments lack the tools and training to effectively identify, shape and execute the broader business strategies that would ultimately deliver the most business impact. Only 28 percent regard themselves as ‘well equipped’ to meet the various tactical and strategic demands now being placed upon them” (Sharp, 2013, pp. 232-233). What if CRE departments were better equipped ... with an approach that enables them to choose the best CRE strategy and portfolio design that adds most value to all stakeholders in the organization?

description: We constrain the evolution of the galaxy stellar mass function from 2 < z < 5 for galaxies with stellar masses as low as 10^5 Msun by combining star formation histories of Milky Way satellite galaxies derived from deep Hubble Space Telescope observations with merger trees from the ELVIS suite of N-body simulations. This approach extends our understanding more than two orders of magnitude lower in stellar mass than is currently possible by direct imaging. We find the faint end slopes of the mass functions to be alpha= -1.42(+0.07/-0.05) at z = 2 and alpha = -1.57^(+0.06/-0.06) at z = 5, and show the slope only weakly evolves from z = 5 to z = 0. Our findings are in stark contrast to a number of direct detection studies that suggest slopes as steep as alpha = -1.9 at these epochs. Such a steep slope would result in an order of magnitude too many luminous Milky Way satellites in a mass regime that is observationally complete (Mstar > 2*10^5 Msun at z = 0). The most recent studies from ZFOURGE and CANDELS also suggest flatter faint end slopes that are consistent with our results, but with a lower degree of precision. This work illustrates the strong connections between low and high-z observations when viewed through the lens of LCDM numerical simulations.

description: We address the question of regular primordial black holes with de Sitter interior, their remnants and gravitational vacuum solitons G-lumps as heavy dark matter candidates providing signatures for inhomogeneity of early universe, which is severely constrained by the condition that the contribution of these objects in the modern density does not exceed the total density of dark matter. Primordial black holes and their remnants seem to be most elusive among dark matter candidates. However, we reveal a nontrivial property of compact objects with de Sitter interior to induce proton decay or decay of neutrons in neutron stars. The point is that they can form graviatoms, binding electrically charged particles. Their observational signatures as dark matter candidates provide also signatures for inhomogeneity of the early universe. In graviatoms, the cross-section of the induced proton decay is strongly enhanced, what provides the possibility of their experimental searches. We predict proton decay paths induced by graviatoms in the matter as an observational signature for heavy dark matter searches at the IceCUBE experiment.

description: Source-free equations of nonlinear electrodynamics minimally coupled to gravity (NED-GR) admit regular axially symmetric asymptotically Kerr-Newman solutions, which describe electrically charged rotating black holes and spinning solitons. Asymptotic analysis of solutions shows the existence of de Sitter vacuum interior which has the properties of a perfect conductor and an ideal diamagnetic. The Kerr ring singularity (a naked singularity in the case without horizons) is replaced with a superconducting current, which serves as a nondissipative source of the Kerr-Newman fields and can be responsible for an unlimited life time of a spinning object.

description: Metal-poor stars in the Milky Way are local relics of the epoch of the first stars and the first galaxies. However, a low metallicity does not prove that a star formed in this ancient era, as metal-poor stars form over a range of redshift in different environments. Theoretical models of Milky Way formation have shown that at constant metallicity, the oldest stars are those closest to the center of the Galaxy on the most tightly-bound orbits. For that reason, the most metal-poor stars in the bulge of the Milky Way provide excellent tracers of the chemistry of the high-redshift universe. We report the dynamics and detailed chemical abundances of three stars in the bulge with [Fe/H] $\lesssim-2.7$, two of which are the most metal-poor stars in the bulge in the literature. We find that with the exception of scandium, all three stars follow the abundance trends identified previously for metal-poor halo stars. These three stars have the lowest [Sc II/Fe] abundances yet seen in $α$-enhanced giant stars in the Galaxy. Moreover, all three stars are outliers in the otherwise tight [Sc II/Fe]-[Ti II/Fe] relation observed among metal-poor halo stars. Theoretical models predict that there is a 30% chance that at least one of these stars formed at $z\gtrsim15$, while there is a 70% chance that at least one formed at $10 \lesssim z \lesssim 15$. These observations imply that by $z\sim10$, the progenitor galaxies of the Milky Way had both reached [Fe/H] $\sim-3.0$ and established the abundance pattern observed in extremely metal-poor stars.

description: Sci-GaIA (www.sci-gaia.eu) is an EU funded project that ran from May 2015 to April 2017. Initially set out to create sustainable training to support scientific endeavour through Science Gateways and e-Infrastructures in Africa. To better motivate and to establish a clearer route to impact, the project shifted focus to embrace Open Science to better open up scientific achievements in Africa across the world. Overall, the Sci-GaIA project has made thousands of people made aware of Science Gateways, e-Infrastructures and Open Science and has created a sustainable ecosystem of Open Science compliant, Open Innovation capable and Open Education based collaboration across Africa. It has also addressed a number of UN Sustainable Development Goals effectively addressed: (3) Good Health and Well-being, (4) Quality Education, (9) Industry, Innovation and Infrastructure, (11) Sustainable Cities and Communities, (13) Climate Action and (17) Partnerships for the Goals. Overall the project has made effective impacts on African health and public health and, consequently, on the quality and duration of life. The major results of the project were: (i) The creation of the Open Science Platform, a DevOps-compliant public research e-Infrastructure (both Grid and Cloud based) for projects and applications, and supporting training and educational materials; (ii) The creation of e-Research Hackfests that uses effective challenge-driven education to train, innovate and create new services, applications and developers; (iii) The creation of 35 Champions who have has supported 24 Communities of Practice, created 7 new Science Gateways, multiple new services and 5 new Open Data Repositories; (iv) A thriving developer community that interacts through the African e Infrastructures Discussion Forum, a web forum where people (users, stakeholders, decision makers) can freely discuss e-Infrastructure and Open Science related topics; (v) A catalogue of services for different types of “customers” that includes 19 new federated services and 30 new applications; (vi) A survey analysing trends in Science Gateway and e-Infrastructure development in Africa; (vii) An approach to ensuring interoperability and interoperation between African, EU and global e-Infrastructures of our Open Science Platform via an e-Infrastructure Sentinel, (viii) The successful creation of 100 dissemination and communication media, publications, many different Sci-GaIA events and the exciting Sci-GaIA Festival of Open Science that combined a Champions conference (the User Forum Conference) and a Final Project day that celebrated the project’s achievements. In this presentation, given at UbuntuNet Connect 2017 Conference (https://events.ubuntunet.net/indico/event/10), we present Sci-GaIA results, share the lessons learnt and discuss the opportunities for the African Communities of Practice to leverage and exploit project results.

description: Quantum state transfer into a memory, state shuttling over long distances via a quantum bus, and high-fidelity readout are important tasks for quantum technology. Realizing these tasks is challenging in the presence of realistic couplings to an environment. Here, we introduce and assess protocols that can be used in cavity QED to perform high-fidelity quantum state transfer and fast quantum nondemolition qubit readout through Hamiltonian engineering. We show that high-fidelity state transfer between a cavity and a single qubit can be performed, even in the limit of strong dephasing due to inhomogeneous broadening. We generalize this result to state transfer between a cavity and a logical qubit encoded in a collective mode of a large ensemble of $N$ physical qubits. Under a decoupling sequence, we show that inhomogeneity in the ensemble couples two collective bright states to only two other collective modes, leaving the remaining $N-3$ single-excitation states dark. Moreover, we show that large signal-to-noise and high single-shot fidelity can be achieved in a cavity-based qubit readout, even in the weak-coupling limit. These ideas may be important for novel systems coupling single spins to a microwave cavity.

description: We present J-band spectroscopy of passive galaxies focusing on the Na I doublet at 1.14 μm. Like the Na I 0.82 μm doublet, this feature is strong in low-mass stars and hence may provide a useful probe of the initial mass function (IMF). From high signal-to-noise composite spectra, we find that Na I 1.14 μm increases steeply with increasing velocity dispersion, σ, and for the most massive galaxies (σ> 300 km/s) is much stronger than predicted from synthetic spectra with Milky-Way-like IMFs and solar abundances. Reproducing Na I 1.14 μm at high σ likely requires either a very high [Na/H], or a bottom-heavy IMF, or a combination of both. Using the Na D line to break the degeneracy between IMF and abundance, we infer [Na/H] $\approx$ +0.5 and a steep IMF (single-slope-equivalent x $\approx$ 3.2, where x = 2.35 for Salpeter), for the high-σgalaxies. At lower mass (σ = 50-100 km/s), the line strengths are compatible with MW-like IMFs and near-solar [Na/H]. We highlight two galaxies in our sample where strong gravitational lensing masses favour MW-like IMFs. Like the high-σ sample on average, these galaxies have strong Na I 1.14 μm; taken in isolation their sodium indices imply bottom-heavy IMFs which are hard to reconcile with the lensing masses. An alternative full-spectrum-fitting approach, applied to the high-σsample, recovers an IMF less heavy than Salpeter, but under-predicts the Na I 1.14 μm line at the 5σ level. We conclude that current models struggle to reproduce this feature in the most massive galaxies without breaking other constraints, and caution against over-reliance on the sodium lines in spectroscopic IMF studies.

description: In nonlinear electrodynamics coupled to gravity, regular spherically symmetric electrically charged solutions satisfy the weak energy condition and have obligatory de Sitter centre. By the Gürses-Gürsey algorithm they are transformed to spinning electrically charged solutions asymptotically Kerr-Newman for a distant observer. Rotation transforms de Sitter center into de Sitter vacuum surface which contains equatorial disk $r=0$ as a bridge. We present general analysis of the horizons, ergoregions and de Sitter surfaces, as well as the conditions of the existence of regular solutions to the field equations. We find asymptotic solutions and show that de Sitter vacuum surfaces have properties of a perfect conductor and ideal diamagnetic, violation of the weak energy condition is prevented by the basic requirement of electrodynamics of continued media, and the Kerr ring singularity is replaced with the superconducting current.

description: A disease that caused by dengue virus (DENV) has become the major health problem of the world. Nowadays, no effective treatment is available to overcome the disease due to the level of dengue virus pathogeneses. A novel treatment method such as antiviral drug is highly necessary for coping with the dengue disease. Envelope protein is one of the non-structural proteins of DENV, which engaged in the viral fusion process. The fusion process is mediated by the conformational change in the protein structure from dimer to trimer state. The previous research showed the existing cavity on the dimer structure of the envelope protein. The existing ligand could get into cavity of the envelope protein, stabilize the dimer structure or hamper the transition of dimer protein into trimer. In this fashion, the fusion process can be prevented. The aim of this research is designing the cyclic peptide with prolin-prolin bond as fusion inhibitor of DENV envelope protein through molecular docking and molecular dynamics simulation. The screening of 3,883 cyclic peptides, each of them connected by prolin-prolin bond, through molecular docking resulted in five best ligands. The pharmacological and toxicity character of these five ligands were analised in silico. The result showed that PYRRP was the best ligand. PAWRP was also chosen as the best ligand because it showed good affinity with protein cavity. Stability of ligand-protein complex was analyzed by molecular dynamics simulation. The result showed that PYRRP ligand was able to support the stability of DENV envelope protein dimer structure at 310 K and 312 K. While PAWRP ligand actively formed complex with the DENV envelope protein at 310 K compared to 312 K. Thus the PYRRP ligand has a potential to be developed as DENV fusion inhibitor.

description: Intellectual and life-skill benefits of collegiate athletics participation have been documented in empirical research, yet athletics-centric curricula are traditionally not offered for academic credit in higher education. This research employed a survey, distributed to college varsity athletes, coaches, athletics administrators, and faculty from three Atlantic Coast Conference institutions, to explore the interest in and design of an athletics performance minor through the lens of the Integrated View of intercollegiate athletics. The results demonstrate a moderate interest in an athletics performance curriculum, with 66% of those surveyed voicing support. Those most supportive were varsity athletes and coaches, while faculty were the most skeptical. Courses most desired for this curriculum were sport psychology and leadership. This study adds to the literature by addressing the philosophical dichotomy that despite the nexus between educational outcomes and athletics, an opportunity for academic credit is lacking.

Hot lower mantle features, such as the thermal footprint of a giant impact or hot mantle plumes, will locally reduce the heat flux through the core mantle boundary (CMB), thereby weakening core convection and affecting the magnetic field generation process. In this study, we numerically investigate how parametrised hot spots at the CMB with arbitrary sizes, amplitudes, and positions affect core convection and hence the dynamo. The effect of the heat flux anomaly is quantified by changes in global flow symmetry properties, such as the emergence of equatorial antisymmetric, axisymmetric (EAA) zonal flows. For purely hydrodynamic models, the EAA symmetry scales almost linearly with the CMB amplitude and size, whereas self-consistent dynamo simulations typically reveal either suppressed or drastically enhanced EAA symmetry depending mainly on the horizontal extent of the heat flux anomaly. Our results suggest that the length scale of the anomaly should be on the same order as the outer core radius to significantly affect flow and field symmetries. As an implication to Mars and in the range of our model, the study concludes that an ancient core field modified by a CMB heat flux anomaly is not able to heterogeneously magnetise the crust to the present-day level of north--south asymmetry on Mars. The resulting magnetic fields obtained using our model either are not asymmetric enough or, when they are asymmetric enough, show rapid polarity inversions, which are incompatible with thick unidirectional magnetisation.

description: The use of integral equation methods for the efficient numerical solution of PDE boundary value problems requires two main tools: quadrature rules for the evaluation of layer potential integral operators with singular kernels, and fast algorithms for solving the resulting dense linear systems. Classically, these tools were developed separately. In this work, we present a unified numerical scheme based on coupling Quadrature by Expansion, a recent quadrature method, to a customized Fast Multipole Method (FMM) for the Helmholtz equation in two dimensions. The method allows the evaluation of layer potentials in linear-time complexity, anywhere in space, with a uniform, user-chosen level of accuracy as a black-box computational method. Providing this capability requires geometric and algorithmic considerations beyond the needs of standard FMMs as well as careful consideration of the accuracy of multipole translations. We illustrate the speed and accuracy of our method with various numerical examples. Keywords: Layer Potentials; Singular Integrals; Quadrature; High-order accuracy; Integral equations; Helmholtz equation; Fast multipole method.

description: The aim of this paper is provide new insights into the properties of the rank 2 polarizability tensor $\check{\check{\mathcal M}}$ proposed in (P.D. Ledger and W.R.B. Lionheart Characterising the shape and material properties of hidden targets from magnetic induction data, IMA Journal of Applied Mathematics, doi: 10.1093/imamat/hxv015) for describing the perturbation in the magnetic field caused by the presence of a conducting object in the eddy current regime. In particular, we explore its connection with the magnetic polarizability tensor and the Pólya-Szegö tensor and how, by introducing new splittings of $\check{\check{\mathcal M}}$, they form a family of rank 2 tensors for describing the response from different categories of conducting (permeable) objects. We include new bounds on the invariants of the Pólya-Szegö tensor and expressions for the low frequency and high conductivity limiting coefficients of $\check{\check{\mathcal M}}$. We show, for the high conductivity case (and for frequencies at the limit of the quasi-static approximation), that it is important to consider whether the object is simply or multiply connected but, for the low frequency case, the coefficients are independent of the connectedness of the object. Furthermore, we explore the frequency response of the coefficients of $\check{\check{\mathcal M}}$ for a range of simply and multiply connected objects.

description: We study M-theory on a Calabi-Yau fourfold with a smooth surface $S$ of $A_{N-1}$ singularities. The resulting three-dimensional theory has a $\mathcal{N}=2$ $SU(N)$ gauge theory sector, which we obtain from a twisted dimensional reduction of a seven-dimensional $\mathcal{N}=1$ $SU(N)$ gauge theory on the surface $S$. A variant of the Vafa-Witten equations governs the moduli space of the gauge theory, which, for a trivial $SU(N)$ principal bundle over $S$, admits a Coulomb and a Higgs branch. In M-theory these two gauge theory branches arise from a resolution and a deformation to smooth Calabi-Yau fourfolds, respectively. We find that the deformed Calabi-Yau fourfold associated to the Higgs branch requires for consistency a non-trivial four-form background flux in M-theory. The flat directions of the flux-induced superpotential are in agreement with the gauge theory prediction for the moduli space of the Higgs branch. We illustrate our findings with explicit examples that realize the Coulomb and Higgs phase transition in Calabi-Yau fourfolds embedded in weighted projective spaces. We generalize and enlarge this class of examples to Calabi-Yau fourfolds embedded in toric varieties with an $A_{N-1}$ singularity in codimension two.

Does the obscured AGN fraction really depend on luminosity?

description: We use a sample of 151 local non-blazar AGN selected from the INTEGRAL all-sky hard X-ray survey to investigate if the observed declining trend of the fraction of obscured (i.e. showing X-ray absorption) AGN with increasing luminosity is mostly an intrinsic or selection effect. Using a torus-obscuration model, we demonstrate that in addition to negative bias, due to absorption in the torus, in finding obscured AGN in hard X-ray flux limited surveys, there is also positive bias in finding unobscured AGN, due to Compton reflection in the torus. These biases can be even stronger taking into account plausible intrinsic collimation of hard X-ray emission along the axis of the obscuring torus. Given the AGN luminosity function, which steepens at high luminosities, these observational biases lead to a decreasing observed fraction of obscured AGN with increasing luminosity even if this fraction has no intrinsic luminosity dependence. We find that if the central hard X-ray source in AGN is isotropic, the intrinsic (i.e. corrected for biases) obscured AGN fraction still shows a declining trend with luminosity, although the intrinsic obscured fraction is significantly larger than the observed one: the actual fraction is larger than $\sim 85$% at $L\lesssim 10^{42.5}$ erg/s (17--60 keV), and decreases to $\lesssim 60$% at $L\gtrsim 10^{44}$ erg/s. In terms of the half-opening angle, $θ$, of an obscuring torus, this implies that $θ\lesssim 30$ deg in lower-luminosity AGN, and $θ\gtrsim 45$ deg in higher-luminosity ones. If, however, the emission from the central SMBH is collimated as $dL/dΩ\propto\cosα$, the intrinsic dependence of the obscured AGN fraction is consistent with a luminosity-independent torus half-opening angle $θ\sim 30$ deg.

An Evaluation of Fatigue Management Strategies Implemented on Hospital Nursing Units

Subjects: subject: Nursing

description: Nursing staff are often scheduled to work long shifts, rotate between day and night shifts, and work overtime to help hospitals ensure delivery of care to patients around the clock, as well as provide nurses work-life balance by giving them more "leisure" or free time away from work. These schedules, now commonplace in hospitals, may unfortunately result in fatigue and sleep deprivation among nurses, negatively affect their work performance by decreasing productivity at work, and, more importantly, make them prone to errors that negatively impact the delivery of safe, quality patient care. This project used a pretest-posttest design to evaluate the effects of fatigue management strategies (namely, duty free breaks, limiting consecutive hours worked, and limiting consecutive shifts) implemented on four adult medical or surgical units at one large academic medical center. Measures used in evaluating the strategies implemented included the Occupational Fatigue Exhaustion Recovery (OFER15) instrument (Winwood et al., 2006), the Pittsburgh Sleep Quality Index (PSQI) instrument (Buysse et al., 1989), medication administration record near miss alerts, absenteeism, and overtime. The major project findings included a significant decrease in reported acute fatigue and an increase in sleep quality among the nursing assistive personnel following the implementation of fatigue management strategies. Additionally, staff on one of the four intervention units reported a significant increase in inter-shift recovery and an improvement in sleep quality following the implementation of fatigue management strategies.

description: Reverse Mathematics is a program in the foundations of mathematics. It provides an elegant classification in which the majority of theorems of ordinary mathematics fall into only five categories, based on the 'Big Five' logical systems. Recently, a lot of effort has been directed towards finding exceptional theorems, i.e. which fall outside the Big Five. The so-called Reverse Mathematics zoo is a collection of such exceptional theorems (and their relations). It was shown in [17] that a number of uniform versions of the zoo-theorems, i.e. where a functional computes the objects stated to exist, fall in the third Big Five category arithmetical comprehension, inside Kohlenbach's higher-order Reverse Mathematics. In this paper, we extend and refine the results from [17]. In particular, we establish analogous results for recent additions to the Reverse Mathematics zoo, thus establishing that the latter disappear at the uniform level. Furthermore, we show that the aforementioned equivalences can be proved using only intuitionistic logic. Perhaps most surprisingly, these explicit equivalences are extracted from nonstandard equivalences in Nelson's internal set theory, and we show that the nonstandard equivalence can be recovered from the explicit ones.

description: We prove the generic base change theorem for stacks, and give an exposition on the lisse-analytic topos of complex analytic stacks, proving some comparison theorems between various derived categories of complex analytic stacks. This enables us to deduce the decomposition theorem for perverse sheaves on complex Artin stacks with affine stabilizers from the case over finite fields.
