description: We present observations of CO J=2-1 line emission in infrared-luminous cluster galaxies at z~1 using the IRAM Plateau de Bure Interferometer. Our two primary targets are optically faint, dust-obscured galaxies (DOGs) found to lie within 2 Mpc of the centers of two massive (>10^14 Msun) galaxy clusters. CO line emission is not detected in either DOG. We calculate 3-sigma upper limits to the CO J=2-1 line luminosities, L'_CO < 6.08x10^9 and < 6.63x10^9 K km/s pc^2. Assuming a CO-to-H_2 conversion factor derived for ultraluminous infrared galaxies in the local Universe, this translates to limits on the cold molecular gas mass of M_H_2 < 4.86x10^9 Msun and M_H_2 < 5.30x10^9 Msun. Both DOGs exhibit mid-infrared continuum emission that follows a power-law, suggesting that an AGN contributes to the dust heating. As such, estimates of the star formation efficiencies in these DOGs are uncertain. A third cluster member with an infrared luminosity, L_IR < 7.4x10^11 Lsun, is serendipitously detected in CO J=2-1 line emission in the field of one of the DOGs located roughly two virial radii away from the cluster center. The optical spectrum of this object suggests that it is likely an obscured AGN, and the measured CO line luminosity is L'_CO = (1.94 +/- 0.35)x10^10 K km/s pc^2, which leads to an estimated cold molecular gas mass M_H_2 = (1.55+/-0.28)x10^10 Msun. A significant reservoir of molecular gas in a z~1 galaxy located away from the cluster center demonstrates that the fuel can exist to drive an increase in star-formation and AGN activity at the outskirts of high-redshift clusters.

0139 Damned Words: The Use and Disuse of "Modern" as an Attribute for the Interpretation of Folk Customs in Theatrical Revue Stage and Costume Design at the Turn of the 1930s in Portugal
Creators: name: Bártolo, Carlos
Publisher: name: RIHA Journal
Year: 2016

description: O Notícias Ilustrado was published from 1928 to 1935, coinciding with the emergence of Salazar's dictatorship. Reporting the cosmopolitan life, it described itself as "the only graphic newspaper of modern and European appearance". Its collaborators included figures from among the Modernist generation that would later be associated with the regime's cultural policy. On its pages one can see a renewal of the theatrical revue format, it covered elements that were a repercussion of the Modernists' interest for folk art and the rediscovery of the national heritage. A straightforward analysis reveals that this reinterpretation of folk traditions was mainly addressed as modern up to the moment when an official culture policy was set; from 1933 onwards this modernity was veiled. In this analysis it could be perceived how similar works, by being addressed differently, could imply the different contexts of 1930s Portugal.

Shedding light on CP violation in the charm system via D to V gamma decays

description: Recent evidence for direct CP violation in non-leptonic charm decays cannot be easily accommodated within the Standard Model (SM). On the other hand, it fits well in new physics models generating CP violating Delta C=1 chromomagnetic dipole operators. We show that in these frameworks sizable direct CP asymmetries in radiative D to P+ P- gamma decays (P=pi,K), with M_PP close to the rho or the phi peak, can be expected. Enhanced matrix elements of the electromagnetic dipole operators can partly compensate the long distance dominance in these decays, leading to CP asymmetries of the order of several percent. If observed at this level, these would provide a clean signal of physics beyond the SM and of new dynamics associated to dipole operators. We briefly comment on related CP violating observables accessible via time dependent D(Dbar) to P+ P- gamma studies and angular decay product distributions in rare semileptonic D decays.

description: Berry curvatures are computed for a set of Heusler compounds using density functional (DF) calculations and the wave functions that DF provide. The anomalous Hall conductivity is obtained from the Berry curvatures. It is compared with experimental values in the case of Co$_2$CrAl and Co$_2$MnAl. A notable trend cannot be seen but the range of values is quite enormous. The results for the anomalous Hall conductivities and their large variations can be qualitatively understood by means of the band structure and the Fermi-surface topology.

description: The half-integer quantum Hall effect in epitaxial graphene is compared with high precision to the well known integer effect in a GaAs/AlGaAs heterostructure. We find no difference between the quantised resistance values within the relative standard uncertainty of our measurement of $8.7\times 10^{-11}$. The result places new tighter limits on any possible correction terms to the simple relation $R_{\rm K}=h/e^2$, and also demonstrates that epitaxial graphene samples are suitable for application as electrical resistance standards of the highest metrological quality. We discuss the characterisation of the graphene sample used in this experiment and present the details of the cryogenic current comparator bridge and associated uncertainty budget.
0146 The Image of Travelling
Creators: name: Lykke Grand, Karina
Publisher: name: RIHA Journal
Year: 2017

description: The Danish painter Martinus Rørbye was one of the Danish artists to reinvent the traditions of the genre of travel painting in the 1830s. His development of a new complex pictorial strategy was in many ways an answer to the changes in society, especially the advent of tourism. The new travel image had its focus on concurrency, everyday life and the secular world, resulting in images that anticipated the photographic travel image, the snapshot and the travel postcard. The advent of this new strategy proved to have a very long after-life, as tourists and travellers of today still lean a great deal on the image codes that Rørbye and his fellow artists of the 1830s invented. The aim of the article is to elaborate on Rørbye’s first European sojourn in 1834-1837, and it is my intention to frame the conditions of doing such a trip with attention to what Rørbye saw and experienced and how he interpreted this knowledge, visually and in words. Rørbye is my primary research focus, but his artistic struggles are very similar to other artists travelling in Italy at the time. I therefore use Martinus Rørbye’s Italian sojourn as a prism of interpretation.

Publisher: name: RIHA Journal
Year: 2017

description: The article discusses the resonance of Michel Ragon’s concept of prospective architecture in Czechoslovakia by taking the group VAL (Voies et Aspects du Lendemain) as an example. The article focuses not only on the similarities, but also on the divergences between the concept of prospective architecture defined in France and VAL’s projects from the 1970s. The article will try to reveal parallels between the VAL’s definition of architecture as a result of a game and a way to anticipate the new society, and the approach of architects and groups active in France as the Utopia, or the Internationale Situationniste. In conclusion, the text will emphasize the specificity of VAL’s projects, inseparably linked to the context of Czechoslovakia during the period of Normalization, and stress its heterogeneous characterlinking them more closely to the postmodern architecture.

description: We present a detailed and unique mass budget for the high-surface-brightness galaxy UGC 463, showing it is dominated by dark matter (DM) at radii beyond one scale length (h_R) and has a baryonic-to-DM mass ratio of approximately 1:3 within 4.2 h_R. Assuming a constant scale height (h_z, calculated via an empirical oblateness relation), we calculate dynamical disk mass surface densities from stellar kinematics, which provide vertical velocity dispersions after correcting for the shape of the stellar velocity ellipsoid (measured to have sigma_theta/sigma_R=1.04 +/- 0.22 and sigma_z/sigma_R=0.48 +/- 0.09). We isolate the stellar mass surface density by accounting for all gas mass components and find an average K-band mass-to-light ratio of 0.22 +/- 0.09 (ran) ^{+0.16}_{-0.15} (sys) M_{sun}/L_{sun}^{K}; Zibetti et al. and Bell et al. predict, respectively, 0.56 and 3.6 times our dynamical value based on stellar-population-synthesis modeling. The baryonic matter is submaximal by a factor of ~3 in mass and the baryonic-to-total circular-speed ratio is 0.61^{+0.07}_{-0.09} (ran) ^{+0.12}_{-0.18} (sys) at 2.2 h_R; however, the disk is globally stable with a multi-component stability that decreases asymptotically with radius to Q~2. We directly calculate the circular speed of the DM halo by subtracting the baryonic contribution to the total circular speed; the result is equally well described by either a Navarro-Frenk-White halo or a pseudo-isothermal sphere. The volume density is dominated by DM at heights of |z|>1.6 h_z for radii of R > h_R. As is shown in follow-up papers, UGC 463 is just one example among nearly all galaxies we have observed that contradict the hypothesis that high-surface-brightness spiral galaxies have maximal disks.

0183 Mark Rothko: Art as an Experience
Creators: name: Christensen, Ruth
Publisher: name: RIHA Journal
Year: 2017

description: This article aims to investigate the possible terms and conditions that Mark Rothko imposes on the encounter between painting and viewer, especially concerning the paintings he made for the Houston Chapel, also called the Rothko Chapel, in 1965-1967, which in many ways differ significantly from his earlier paintings. In particular, the article seeks to throw light upon as well as to discuss the conditions that allow the viewer to interact with the paintings and derive a kind of meaning or content from the paintings and, on the other hand, the limitations and paradoxes that meet the viewer in that same process. Conclusively, the article suggests a nuanced view on the chapel paintings recognizing that these dark, inaccessible, almost monochrome paintings contribute to an essential discussion of the very role and meaning of art in a late modern context.

Nearly extensive sequential memory lifetime achieved by coupled nonlinear neurons

Publisher: name: arXiv
Year: 2012
Subjects: subject: Neurons and Cognition (q-bio.NC)
subject: FOS: Biological sciences

description: Many cognitive processes rely on the ability of the brain to hold sequences of events in short-term memory. Recent studies have revealed that such memory can be read out from the transient dynamics of a network of neurons. However, the memory performance of such a network in buffering past information has only been rigorously estimated in networks of linear neurons. When signal gain is kept low, so that neurons operate primarily in the linear part of their response nonlinearity, the memory lifetime is bounded by the square root of the network size. In this work, I demonstrate that it is possible to achieve a memory lifetime almost proportional to the network size, "an extensive memory lifetime", when the nonlinearity of neurons is appropriately utilized. The analysis of neural activity revealed that nonlinear dynamics prevented the accumulation of noise by partially removing noise in each time step. With this error-correcting mechanism, I demonstrate that a memory lifetime of order $N/\log N$ can be achieved.

description: We numerically analyze the dynamical generation of quantum entanglement in a system of 2 interacting particles, started in a coherent separable state, for decreasing values of $\hbar$. As $\hbar\to 0$ the entanglement entropy, computed at any finite time, converges to a finite nonzero value. The limit law that rules the time dependence of entropy is well reproduced by purely classical computations. Its general features may then be explained by simple classical arguments, which expose the different ways entanglement is generated in systems which are classically chaotic or regular.

description: Over the 20 years from 1885 to 1905 Calgary grew from a town of just over 500 people to a city of over 12,000. The major commercial civic, institutional and industrial buildings of these years were constructed predominantly of sandstone. Today those which remain provide Calgary with a singularly valuable architectural resource, the preservation of which requires detail ed technical information on approaches to the maintenance and repair of their principal material; sandstone. Unfortunately such information is generally not available, or not related specifically to Calgary Sandstone. Nor does the training or experience of the present day architect or contractor provide him with the special knowledge required; concentrating as it does on modern day materials and practice. This project provides the architect or contractor involved in the task of maintaining or repairing a sandstone building with an understanding of the material he is dealing with, and with the specific detailed technical information required for its appropriate preservation, or repair. Firstly, the project investigates how Calgary sandstone was used, examines its structure and composition and how these affect its durability, and considers the question of how the stone deteriorates in use. The remainder of the project discusses specific preservation and restoration techniques, which are available to architects and contractors, including a guide to the formulation and implementation of a program for maintenance or repair that is keyed to detailed technical discussions on masonry cleaning, preservation, and replacement or repair.

description: We consider five-dimensional Einstein-Maxwell-Kalb-Ramond system self-consistently coupled to a lightlike 3-brane, where the latter acts as material, charge and variable cosmological constant source. We find wormhole-like solutions whose total space-time manifold consists of either (a) two "universes", which are identical copies of the exterior space-time region (beyond the horizon) of 5-dimensional Schwarzschild-anti-de Sitter black hole, or (b) a "right" "universe" comprising the exterior space-time region of Reissner-Nordstroem-anti-de Sitter black hole and a "left" "universe" being the Rindler "wedge" of 5-dimensional flat Minkowski space. The wormhole "throat" connecting these "universes", which is located on their common horizons, is self-consistently occupied by the lightlike 3-brane as a direct result of its dynamics given by an explicit reparametrization-invariant world-volume Lagrangian action. The intrinsic world-volume metric on the 3-brane turns out to be flat, which allows its interpretation as a lightlike braneworld.

description: Robert Tischler, the chief architect of the German War Graves Commission from 1926 until his death in 1959, decisively shaped the character of German war cemeteries at home and abroad. Interestingly, the size of the oeuvre does not correspond to the very few facts we know about the author. This article explains the biographical and structural reasons for this situation, among them the bias of art and architectural history to focus on progress and innovation. It pleads for a thorough investigation of both the architect and his oeuvre that considers the context of production, distribution, and reception.

description: This paper is devoted to the spectral theory of the Schrödinger operator on the simplest fractal: Dyson's hierarchical lattice. An explicit description of the spectrum, eigenfunctions, resolvent and parabolic kernel are provided for the unperturbed operator, i.e., for the Dyson hierarchical Laplacian. Positive spectrum is studied for the perturbations of the hierarchical Laplacian. Since the spectral dimension of the operator under consideration can be an arbitrary positive number, the model allows a continuous phase transition from recurrent to transient underlying Markov process. This transition is also studied in the paper.

description: The presence of substructure in galaxy groups and clusters is believed to be a sign of recent galaxy accretion and can be used not only to probe the assembly history of these structures, but also the evolution of their member galaxies. Using the Dressler-Shectman (DS) Test, we study substructure in a sample of intermediate redshift (z ~ 0.4) galaxy groups from the Group Environment and Evolution Collaboration (GEEC) group catalog. We find that 4 of the 15 rich GEEC groups, with an average velocity dispersion of ~525 km s-1, are identified as having significant substructure. The identified regions of localized substructure lie on the group outskirts and in some cases appear to be infalling. In a comparison of galaxy properties for the members of groups with and without substructure, we find that the groups with substructure have a significantly higher fraction of blue and star-forming galaxies and a parent colour distribution that resembles that of the field population rather than the overall group population. In addition, we observe correlations between the detection of substructure and other dynamical measures, such as velocity distributions and velocity dispersion profiles. Based on this analysis, we conclude that some galaxy groups contain significant substructure and that these groups have properties and galaxy populations that differ from groups with no detected substructure. These results indicate that the substructure galaxies, which lie preferentially on the group outskirts and could be infalling, do not exhibit signs of environmental effects, since little or no star-formation quenching is observed in these systems.

0169 Nationale Folklore und politischer Totenkult

Publisher: name: RIHA Journal

description: This article discusses symbolic forms and the association of folklore and politics in the Riga Brethren Cemetery (Brāļu Kapi). The iconographic and formal analysis of this memorial sheds light on its function as a place of worship for those who fell in action while fighting for the sovereignty of the Latvian people. Considering that Latvia suffered severely from different foreign rules over the past centuries, the memorial has contributed to strengthen nationalistic movements in Latvian society and has played an important role in nation-building. The cemetery’s landscape design as well as its large-scale monuments by the Latvian sculptor Kārlis Zāle (1888-1942) borrowed their themes from Latvian mythology. After investigating another major work of Zāle, the Freedom Monument in Riga, I analyse the main elements of the sculptural ensemble of the Brethren Cemetery. Eventually, I outline how the political circumstances have influenced the burial practices over the decades. With Latvia celebrating the centennial of its first proclamation of independence in 2018, the restoration of this memorial has been undertaken in recent years.

description: We propose the following model equation: \[u_{t}+1/2(u^{2}-uu_{s})_{x}=f(x,u_{s}), \] that predicts chaotic shock waves. It is given on the half-line $x<0$ and the shock is located at $x=0$ for any $t\ge0$. Here $u_{s}(t)$ is the shock state and the source term $f$ is assumed to satisfy certain integrability constraints as explained in the main text. We demonstrate that this simple equation reproduces many of the properties of detonations in gaseous mixtures, which one finds by solving the reactive Euler equations: existence of steady traveling-wave solutions and their instability, a cascade of period-doubling bifurcations, onset of chaos, and shock formation in the reaction zone.

description: After World War II, the communist party took control of the nation-building process of the newly established Socialist Federal Republic of Yugoslavia. World War II played a major role in the narration and was reinterpreted as the People's Revolution. The union of war veterans took part in this process by influencing federal legislation as well as the setting-up of war graves and memorials. In 1959, the municipality of Mostar decided to build a partisan cemetery, and commissioned the architect Bogdan Bogdanović to build it. Bogdanović planned a vast war cemetery surrounded by a large park area, with the memorial park embedded into the structure of the city. The main axes of the park are oriented towards important urban spots like the old town. Though – or rather precisely because – the monument has a high urbanistic, historic, and artistic value, it has recently been a target of politically motivated attacks.

We investigate the three different kinds of radio bursts from cusps, kinks, and kink-kink collisions on superconducting strings. We find that the event rate is dominated by kink bursts in a range of parameters that are of observational interest, and can be quite high (several a day at 1 Jy flux) for a canonical set of parameters. In the absence of events, the search for radio transients can place stringent constraints on superconducting cosmic strings.

0223 The Emperor as Living Image in Late Antique Authors
Creators: name: Neri, Valerio
Publisher: name: RIHA Journal
Year: 2019

description: Between the early imperial and early Byzantine periods, in descriptions of the ruler’s body we can identify, grosso modo, two main tendencies: A realistic strain (as exemplified by the imperial portraits in Svetonius) that is anti-iconic in that it prevented the idealisation of the ruler often found in his sculpted portraits; and another, present in particular in encomiastic literature, that followed these idealised artistic presentations. The encomiastic literature from Constantine’s I (r. 306–337) to Theodosius’ I (r. 379–395) time still places the accent on the ruler’s physical beauty as an expression of the particular relationship he had with the divine sphere. The first impression that Constantine’s appearance leaves in the bishops gathered at Nicaea in the description of Eusebius of Caesarea is that of an angelic apparition. In Late Antiquity both in Christian and pagan authors, the main characteristic of the new canon of imperial beauty was light. This light prevents the perception of the sovereign’s body and is considered in texts of the time as either an expression of the absolute distance between the emperor and common human nature, or a vain spectacle. The key text for imperial self-display in Late Antiquity is the famous description of Constantius’ II (r. 337–361) adventus to Rome. In Christian authors writing about angels, the model of beauty that the emperor referenced was the glorious Christ reigning in heaven.

description: The Glenbow Museum, located in downtown Calgary, has experienced a shortage of space for exhibition and support functions. This Master's Degree Project constitutes a conceptual proposal for an extension of this museum. The design described in this document relies on a programme formed with the cooperation of Mr John Vollmer, the Glenbow Museum's Senior Art Curator. It is not intended as an alternate design to the original proposals prepared by the Glenbow. The proposed extension would for a major urban element contributing to the "sense of place" of this downtown area. Chapter One and Two introduce the problem and describe the proposed site and its context. Chapter Three gives a description of the proposed urban and architectural programmes . Chapter Four addresses design concepts and analyzes various extension elements. Chapter Five briefly outlines the building systems.

description: High-energy neutrinos, arising from decays of mesons produced through the collisions of cosmic ray particles with air nuclei, form the background in the astrophysical neutrino detection problem. An ambiguity in high-energy behavior of pion and especially kaon production cross sections for nucleon-nucleus collisions may affect essentially the calculated neutrino flux. We present results of the calculation of the energy spectrum and zenith-angle distribution of the muon and electron atmospheric neutrinos in the energy range 10 GeV to 10 PeV. The calculation was performed with usage of known hadronic models (QGSJET-II-03, SIBYLL 2.1, Kimel & Mokhov) for two of the primary spectrum parametrizations, by Gaisser & Honda and by Zatsepin & Sokolskaya. The comparison of the calculated muon neutrino spectrum with the IceCube40 experiment data make it clear that even at energies above 100 TeV the prompt neutrino contribution is not so apparent because of tangled uncertainties of the strange (kaons) and charm (D-mesons) particle production cross sections. An analytic description of calculated neutrino fluxes is presented.

Detection of Elements at All Three r-process Peaks in the Metal-Poor Star HD 160617

description: We report the first detection of elements at all three r-process peaks in the metal-poor halo star HD 160617. These elements include arsenic and selenium, which have not been detected previously in halo stars, and the elements tellurium, osmium, iridium, and platinum, which have been detected previously. Absorption lines of these elements are found in archive observations made with the Space Telescope Imaging Spectrograph onboard the Hubble Space Telescope. We present up-to-date absolute atomic transition probabilities and complete line component patterns for these elements. Additional archival spectra of this star from several ground-based instruments allow us to derive abundances or upper limits of 45 elements in HD 160617, including 27 elements produced by neutron-capture reactions. The average abundances of the elements at the three r-process peaks are similar to the predicted solar system r-process residuals when scaled to the abundances in the rare earth element domain. This result for arsenic and selenium may be surprising in light of predictions that the production of the lightest r-process elements generally should be decoupled from the heavier r-process elements.

description: We study the Wheeler-DeWitt quantum cosmology of a spatially flat Friedmann cosmological model with a massless free scalar field. We compare the consistent histories approach with the de Broglie-Bohm theory when applied to this simple model under two different quantization schemes: the Schrödinger-like quantization, which essentially takes the square-root of the resulting Klein-Gordon equation through the restriction to positive frequencies and their associated Newton-Wigner states, or the induced Klein-Gordon quantization, that allows both positive and negative frequencies together. We show that the consistent histories approach can give a precise answer to the question concerning the existence of a quantum bounce if and only if one takes the single frequency approach and within a single family of histories, namely, a family containing histories concerning properties of the quantum system at only two specific moments of time: the infinity past and the infinity future. In that case, as shown by Craig and Singh \cite{CS}, there is no quantum bounce. In any other situation, the question concerning the existence of a quantum bounce has no meaning in the consistent histories approach. On the contrary, we show that if one considers the de Broglie-Bohm theory, there are always states where quantum bounces occur in both quantization schemes. Hence the assertion that the Wheeler-DeWitt quantization does not solve the singularity problem in cosmology is not precise. To address this question, one must specify not only the quantum interpretation adopted but also the quantization scheme chosen.

Theoretical studies of the spin Hamiltonian parameters for the two tetragonal Cu$^{2+}$ centers in the calcined catalysts CuO-ZnO

description: The spin Hamiltonian parameters for the two Cu$^{2+}$ centers $A1$ and $A2$ in the calcined catalysts CuO-ZnO are theoretically investigated using the high order perturbation formulas of these parameters for a $3d^{9}$ ion in tetragonally elongated octahedra. In the above formulas, the tetragonal field parameters $Ds$ and $Dt$ are determined from the superposition model, by considering the relative axial elongation of the oxygen octahedron around the Cu$^{2+}$ due to the Jahn-Teller effect. Based on the calculations, the relative elongation ratios of about 5% and 3% are obtained for the tetragonal Cu$^{2+}$ centers $A1$ and $A2$, respectively. The theoretical spin Hamiltonian parameters are in good agreement with the observed values for both systems. The larger axial elongation in center $A1$ is ascribed to the more significant low symmetrical (tetragonal) distortion of the Jahn-Teller effect. The local structures characterized by the above axial elongations are discussed.

description: In the last few years development of Python code for science and data reduction purposes has gained significant popularity. ESO in itself uses a Python-based archiving  system for VLT and ALMA data. Also the data reduction suite for ALMA data is python-based. Rapid development is fostered by a big community and a wide range of already available packages. However Python enforces locking mechanisms, to ensure thread safety, that effectively reduce the capacity of Python to use only one core. In this context a number of alternatives have been developed by the community to emulate actual multi-threading and make parallel processing easier to use from Python, preserving interactivity.

description: We present 13 cm and 20 cm radio observations of the magnetic chemically peculiar star CU Virginis taken with the Australia Telescope Compact Array. We detect two circularly polarised radio pulses every rotation period which confirm previous detections. In the first pulse, the lower frequency emission arrives before the higher frequency emission and the ordering reverses in the second pulse. In order to explain the frequency dependence of the time between the two pulses, we construct a geometric model of the magnetosphere of CU Virginis, and consider various emission angles relative to the magnetic field lines. A simple electron cyclotron maser emission model, in which the emission is perpendicular to the magnetic field lines, is not consistent with our data. A model in which the emission is refracted through cold plasma in the magnetosphere is shown to have the correct pulse arrival time frequency dependence.

description: The structure of the solar chromosphere is believed to be governed by magnetic fields, even in quiet-Sun regions that have a relatively weak photospheric field. During the past decade inversion methods have emerged as powerful tools for analyzing the chromosphere of active regions. The applicability of inversions to infer the stratification of the physical conditions in a dynamic 3D solar chromosphere has not yet been studied in detail. This study aims to establish the diagnostic capabilities of non-local thermodynamical equilibrium (NLTE) inversion techniques of Stokes profiles induced by the Zeeman effect in the Ca II 8542 line. We computed the Ca II atomic level populations in a snapshot from a 3D radiation-MHD simulation of the quiet solar atmosphere in non-LTE using the 3D radiative transfer code Multi3d. These populations were used to compute synthetic full-Stokes profiles in the Ca II 8542 line using 1.5D radiative transfer and the inversion code Nicole. The profiles were then spectrally degraded to account for finite filter width and Gaussian noise was added to account for finite photon flux. These profiles were inverted using Nicole and the results were compared with the original model atmosphere. Our NLTE inversions applied to quiet-Sun synthetic observations provide reasonably good estimates of the chromospheric magnetic field, line-of-sight velocities and somewhat less accurate, but still very useful, estimates of the temperature. Three dimensional scattering of photons cause cool pockets in the chromosphere to be invisible in the line profile and consequently they are also not recovered by the inversions. To successfully detect Stokes linear polarization in this quiet snapshot, a noise level below 10^{-3.5} is necessary.
