description: In this work we study zero-temperature phases of the anisotropic Hubbard model on a three-dimensional cubic lattice in a weak coupling regime. It is known that, at half-filling, the ground state of this model is antiferromagnetic (commensurate spin-density wave). For non-zero doping, various types of spatially inhomogeneous phases, such as phase-separated states and the state with domain walls ("soliton lattice"), can emerge. Using the mean-field theory, we evaluate the free energies of these phases to determine which of them could become the true ground state in the limit of small doping. Our study demonstrates that the free energies of all discussed states are very close to each other. Smallness of these energy differences suggests that, for a real material, numerous factors, unaccounted by the model, may arbitrary shift the relative stability of the competing phases. This further implies that purely theoretical prediction of the true ground state in a particular many-fermion system is unreliable.

Afferent drama / efferent cinema: the structure of modern Canadian and Québécois film-mediated drama from 1972 to 1992
Creators: name: Loiselle, André
Publisher: name: University of British Columbia
Year: 2009

description: The great majority of the Canadian and Quebecois plays that have been made into films between 1972 and 1992 are neither popular hits nor critically acclaimed works. The question that this dissertation poses is thus why were these rather marginal works adapted for the cinema? The suggested answer is that, beyond the critical or popular success of the plays (or lack thereof), it is their dialectical structure that gives coherence, through recursive symmetry, to the corpus of Canadian/Quebecois film-mediated drama. To buttress this claim, I conduct a tripartite analysis of the plays and films of the corpus: the first section is devoted to the dramas; the second scrutinizes the process of film-mediation; and the third evaluates the significance of the corpus in relation to various theoretical and cultural discourses. I examine four texts in detail: William Fruet's Wedding in White (film: Fruet); Marcel Dube's Les Beaux Dimanches (film: Richard Martin); Carol Bolt's One Niaht Stand (film: Allan W. King); and Rene-Daniel Dubois's Being at Home with Claude, (film: Jean Beaudin). Subsequently, a brief survey of other works shows that the conclusions drawn from these case studies also apply to the corpus as a whole. To realize this analysis, I follow the structuralist methodology proposed by Thomas Price in Dramatic Structure and Meaning in Theatrical Productions (1992), which explicates dramas and films in terms of the dialectical conflicts that they display. The first phase of inquiry shows that the plays exhibit an afferent-withdrawal/efferent-escape dialectic, that is, a tension between a coercive inward pressure and an explosive outward force. The second part argues that this tension finds further expression in the cinematic adaptations, as the closed dramas are "opened up" through the addition of outward filmic imagery. The final part suggests that this tension constitutes a key characteristic of film-mediated drama as a genre, for it embodies the clash between a dramatic concentration on a nucleus of characters (afferent drama), and a filmic tendency to explode this nucleus (efferent cinema). Part III evidences as well that the afferent-withdrawal/efferent-escape dialectic relates to a prototypical expression of the Canadian/Quebecois imagination as defined by Canadian studies scholars such as Gaile McGregor.

description: We propose a new form of the inversion method in terms of a selfenergy expansion to access the phase diagram of the Bose-Einstein transition. The dependence of the critical temperature on the interaction parameter is calculated. This is discussed with the help of a new condition for Bose-Einstein condensation in interacting systems which follows from the pole of the T-matrix in the same way as from the divergence of the medium-dependent scattering length. A many-body approximation consisting of screened ladder diagrams is proposed which describes the Monte Carlo data more appropriately. The specific results are that a non-selfconsistent T-matrix leads to a linear coefficient in leading order of 4.7, the screened ladder approximation to 2.3, and the selfconsistent T-matrix due to the effective mass to a coefficient of 1.3 close to the Monte Carlo data.
On the distinction between false belief understanding and the acquisition of an interpretive theory of mind
Creators: name: Carpendale, Jeremy Ian Maxwell
Publisher: name: University of British Columbia
Year: 2009

description: Two groups of 5- to 8-year-olds, and a comparison sample of adults, were examined in an effort to explore the developing relationships between false belief understanding and an awareness of the individualized nature of personal taste, on the one hand, and, on the other, a maturing grasp of the interpretive character of the knowing process. In Study 1,20 children between 5 and 8, and in Study Two, a group of 15 adults, all behaved in accordance with hypotheses by proving to be indistinguishable in their good grasp of the possibility of false beliefs, and in their common assumption that differences of opinion concerning matters of taste are legitimate expressions of personal preferences. By contrast, only the 7- and 8-year-old children and adults gave evidence of recognizing that ambiguous stimuli allow for warrantable differences of interpretation. Study 3 replicated and extended these findings with a group of 48 5- to 8-year-old subjects, again showing that while 5-year-olds easily pass a standard test of false belief understanding, only children of 7 or 8 ordinarily evidence an appreciation of the interpretative character of the knowing process.

description: Planetary formation is an efficient process now thought to take place on a relatively short astronomical time scale. Recent observations have shown that the dust surrounding a protostar emits more efficiently at longer wavelengths as the protoplanetary disk evolves, suggesting that the dust particles are coagulating into fluffy aggregates, "much as dust bunnies form under a bed." One poorly understood problem in this coagulation process is the manner in which micron-sized, charged grains form the fractal aggregate structures now thought to be the precursors of protoplanetary disk evolution. This study examines the characteristics of such fractal aggregates formed by the collision of spherical monomers and aggregates where the charge is distributed over the aggregate structure. The aggregates are free to rotate due to collisions and dipole-dipole electrostatic interactions. Comparisons are made for different precursor size distributions and like-charged, oppositelycharged, and neutral grains.
Potential and scientific requirements of optical clock networks for validating satellite gravity missions

description: The GRACE and GRACE-FO missions have provided an unprecedented quantification of large-scale changes in the water cycle. However, it is still an open problem of how these missions' data sets can be referenced to a ground truth. Meanwhile, stationary optical clocks show fractional instabilities below $10^{-18}$ when averaged over an hour, and continue to be improved in terms of precision and accuracy, uptime, and transportability. The frequency of a clock is affected by the gravitational redshift, and thus depends on the local geopotential; a relative frequency change of $10^{-18}$ corresponds to a geoid height change of about $1$ cm. Here we suggest that this effect could be further exploited for sensing large-scale temporal geopotential changes via a network of clocks distributed at the Earth's surface. In fact, several projects have already proposed to create an ensemble of optical clocks connected across Europe via optical fibre links. Our hypothesis is that a clock network with collocated GNSS receivers spread over Europe - for which the physical infrastructure is already partly in place - would enable us to determine temporal variations of the Earth's gravity field at time scales of days and beyond, and thus provide a new means for validating satellite missions such as GRACE-FO or a future gravity mission. Here, we show through simulations how ice, hydrology and atmosphere variations over Europe could be observed with clock comparisons in a future network that follows current design concepts in the metrology community. We assume different scenarios for clock and GNSS uncertainties and find that even under conservative assumptions - a clock error of $10^{-18}$ and vertical height control error of $1.4$ mm for daily measurements - hydrological signals at the annual time scale and atmospheric signals down to the weekly time scale could be observed.

Bubbles and Filaments: Stirring a Cahn-Hilliard Fluid

Year: 2006
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: The advective Cahn-Hilliard equation describes the competing processes of stirring and separation in a two-phase fluid. Intuition suggests that bubbles will form on a certain scale, and previous studies of Cahn-Hilliard dynamics seem to suggest the presence of one dominant length scale. However, the Cahn-Hilliard phase-separation mechanism contains a hyperdiffusion term and we show that, by stirring the mixture at a sufficiently large amplitude, we excite the diffusion and overwhelm the segregation to create a homogeneous liquid. At intermediate amplitudes we see regions of bubbles coexisting with regions of hyperdiffusive filaments. Thus, the problem possesses two dominant length scales, associated with the bubbles and filaments. For simplicity, we use use a chaotic flow that mimics turbulent stirring at large Prandtl number. We compare our results with the case of variable mobility, in which growth of bubble size is dominated by interfacial rather than bulk effects, and find qualitatively similar results.

description: The aim of the present thesis was the investigation of the SRTM (resolution of 3" ~ 90 m) and ASTER (resolution of 1" ~ 30 m) DTMs to gravity field and geoid modeling. Four types of topographic corrections on gravity anomalies and disturbances, geoid heights and deflections of vertical were computed. These are the full topographic effects, i.e., the combined effect of the Bouguer and terrain corrections, the terrain correction effects (TC), the residual terrain model effects (RTM) and the isostatic effects using the Airy – Heiskanen model. Additionally, the aliasing effects on gravity anomalies and geoid heights were studied through a number of numerical tests using DTMs of lower resolution and produced from the original ones. The results of the computations for the two DTMs were compared and commented with respect to their accuracy and statistical characteristics.

description: A disordered array of metal grains with large and random intergrain conductances is studied within the one-loop accuracy renormalization group approach. While at low level of disorder the dependence of conductivity on log T is nonuniversal (it depends on details of the array's geometry), for strong disorder this dependence is described by a universal nonlinear function, which depends only on the array's dimensionality. In two dimensions this function is found numerically. The dimensional crossover in granular films is discussed.

Theory of stripes in quasi two dimensional rare-earth tritellurides

description: Even though the rare-earth tritellurides are tetragonal materials with a quasi two dimensional (2D) band structure, they have a "hidden" 1D character. The resultant near-perfect nesting of the Fermi surface leads to the formation of a charge density wave (CDW) state. We show that for this band structure, there are two possible ordered phases: A bidirectional "checkerboard" state would occur if the CDW transition temperature were sufficiently low, whereas a unidirectional "striped" state, consistent with what is observed in experiment, is favored when the transition temperature is higher. This result may also give some insight into why, in more strongly correlated systems, such as the cuprates and nickelates, the observed charge ordered states are generally stripes as opposed to checkerboards.

Cosmological Effects of Powerful AGN Outbursts in Galaxy Clusters: Insights from an XMM-Newton Observation of MS0735+7421

description: We report on the results of an analysis of XMM-Newton observations of MS0735+7421, the galaxy cluster which hosts the most energetic AGN outburst currently known. The previous Chandra image shows twin giant X-ray cavities (~200 kpc diameter) filled with radio emission and surrounded by a weak shock front. XMM data are consistent with these findings. The total energy in cavities and shock (~6 \times 10^{61} erg) is enough to quench the cooling flow and, since most of the energy is deposited outside the cooling region (~100 kpc), to heat the gas within 1 Mpc by ~1/4 keV per particle. The cluster exhibits an upward departure (factor ~2) from the mean L-T relation. The boost in emissivity produced by the ICM compression in the bright shells due to the cavity expansion may contribute to explain the high luminosity and high central gas mass fraction that we measure. The scaled temperature and metallicity profiles are in general agreement with those observed in relaxed clusters. Also, the quantities we measure are consistent with the observed M-T relation. We conclude that violent outbursts such as the one in MS0735+7421 do not cause dramatic instantaneous departures from cluster scaling relations (other than the L-T relation). However, if they are relatively common they may play a role in creating the global cluster properties.

Let $\overline{X}$ and $\overline{S}$ be their base changes to an algebraic closure of $\mathbb{F}_q$. We study the number of $\ell$-adic local systems $(\ell\neq p)$ in rank $2$ over $\overline{X}-\overline{S}$ with all possible prescribed tame local monodromies fixed by $k$-fold iterated action of Frobenius endomorphism for every $k\geq 1$. In all cases, we confirm conjectures of Deligne predicting that these numbers behave as if they were obtained from a Lefschetz fixed point formula. In fact, our counting results are expressed in terms of the numbers of some Higgs bundles.

description: Automatic emotion recognition is an active research topic with wide range of applications. Due to the high manual annotation cost and inevitable label ambiguity, the development of emotion recognition dataset is limited in both scale and quality. Therefore, one of the key challenges is how to build effective models with limited data resource. Previous works have explored different approaches to tackle this challenge including data enhancement, transfer learning, and semi-supervised learning etc. However, the weakness of these existing approaches includes such as training instability, large performance loss during transfer, or marginal improvement. In this work, we propose a novel semi-supervised multi-modal emotion recognition model based on cross-modality distribution matching, which leverages abundant unlabeled data to enhance the model training under the assumption that the inner emotional status is consistent at the utterance level across modalities. We conduct extensive experiments to evaluate the proposed model on two benchmark datasets, IEMOCAP and MELD. The experiment results prove that the proposed semi-supervised learning model can effectively utilize unlabeled data and combine multi-modalities to boost the emotion recognition performance, which outperforms other state-of-the-art approaches under the same condition. The proposed model also achieves competitive capacity compared with existing approaches which take advantage of additional auxiliary information such as speaker and interaction context.

description: Η ενασχόληση με την ποίηση του Οδυσσέα Ελύτη φανερώνει τη σχέση του με τη φιλοσοφία. Ο ποιητής είναι εξοικειωμένος με πολλές περιοχές της, έχει εντρυφήσει στο στοχασμό αρκετών φιλοσόφων, και προτείνει ο ίδιος μια φιλοσοφική προσέγγιση του ποιητικού. Εν προκειμένω, με αφορμή το ποίημα «Τα δύο του κόσμου», εξετάζεται η σχέση του Ελύτη με τη φιλοσοφία γενικά, αλλά και με τρεις στοχαστές: τον Πλωτίνο, τον Martin Heidegger και τον Henry Corbin. Μέσα από αναφορές στην ποιητική και δοκιμιακή παραγωγή του Ελύτη, γίνεται λόγος για τις κεντρικές έννοιες της ποιητικής του: τη διαφάνεια, τον έρωτα, την ηλιακή μεταφυσική. Πιο ειδικά, η ποίηση, και μέσα από αυτήν το είναι, η ζωή και ο θάνατος, αποτελούν τον άξονα της συνάρτησης του Ελύτη με τον Heidegger, το σύμπαν της ηλιακής μεταφυσικής και οι αντίστοιχες ποιητικές μορφές αποτελούν την αφορμή της παράλληλης ανάγνωσης του Ελύτη με τον Corbin, και ο έρωτας, η έκσταση και το μυστικό βίωμα δίνουν τη βάση της αναλογίας της σκέψης του ποιητή με εκείνη του Πλωτίνου. Ζητούμενο είναι να αντιμετωπιστεί το ποίημα (κάθε ποίημα) όχι σαν ποιητικό αντικείμενο του ποιητή, αλλά ως ποιητικό υποκείμενο, ικανό να αναπτύξει μια προσωπική σχέση με ένα άλλο υποκείμενο (τον αναγνώστη) και, τελικά, μέσα από τον ποιητή και το ποίημα, να διαφανεί το τέλος: η Ποίηση.
description: Occupation with the poetry of Odysseus Elytis reveals his association with philosophy. The poet, being familiar with philosophy and the thought of many philosophers, suggests a philosophical approach of the poetic. In this work, based on the poem “The two of the world”, we try to investigate the relationship of Elytis with philosophy, in general, and especially his connection with three thinkers: Plotinus, Martin Heidegger and Henry Corbin. Through references to the poems and essays of Elytis, central concepts of his poetic, like transparency, eros and solar metaphysics, are approached. In especial, the poetry, and through that, being, eros and death reveal the connection between Elytis and Heidegger. On the other hand, the universe of the solar metaphysics and the poetic forms, justify a parallel reading of Elytis and Corbin. Finally, eros, ecstasy and the mystical experience create the necessary occasion for an analogy between the thought of the poet and that of Plotinus. The challenge is to think about the poem (every poem) not as a poetic object of the poet, but as a poetic subject, that is able to develop a personal relation with another subject (the reader) and, finally, through the poet and the poem, to suggest the end: Poetry.

description: Remote detectability is often taken as a physical assumption in the study of topologically ordered systems, and it is a central axiom of mathematical frameworks of topological quantum field theories. We show under the entanglement bootstrap approach that remote detectability is a necessary property; that is, we derive it as a theorem. Starting from a single wave function on a topologically-trivial region satisfying the entanglement bootstrap axioms, we can construct states on closed manifolds. The crucial technique is to immerse the punctured manifold into the topologically trivial region and then heal the puncture. This is analogous to Kirby's torus trick. We then analyze a special class of such manifolds, which we call pairing manifolds. For each pairing manifold, which pairs two classes of excitations, we identify an analog of the topological $S$-matrix. This pairing matrix is unitary, which implies remote detectability between two classes of excitations. These matrices are in general not associated with the mapping class group of the manifold. As a by-product, we can count excitation types (e.g., graph excitations in 3+1d). The pairing phenomenon occurs in many physical contexts, including systems in different dimensions, with or without gapped boundaries. We provide a variety of examples to illustrate its scope.

description: The NA60 experiment has studied low-mass muon pair production in In-In collisions at $158 {\rm AGeV}$ with unprecedented precision. With these results there is hope that the in-medium modifications of the vector meson spectral function can be constrained more thoroughly than before. We investigate in particular what can be learned about collisional broadening by a hot and dense medium and what constrains the experimental results put on in-medium mass shift scenarios. The data show a clear indication of considerable in-medium broadening effects but disfavor mass shift scenarios where the $ρ$-meson mass scales with the square root of the chiral condensate. Scaling scenarios which predict at finite density a dropping of the $ρ$-meson mass that is stronger than that of the quark condensate are clearly ruled out since they are also accompanied by a sharpening of the spectral function.

description: We develop a scaling ansatz for the master equation in Dvali, Gabadadze, Porrati cosmologies, which allows us to solve the equations of motion for perturbations off the brane during periods when the on-brane evolution is scale-free. This allows us to understand the behavior of the gravitational potentials outside the horizon at high redshifts and close to the horizon today. We confirm that the results of Koyama and Maartens are valid at scales relevant for observations such as galaxy-ISW correlation. At larger scales, there is an additional suppression of the potential which reduces the growth rate even further and would strengthen the ISW effect.

description: Continuing the photoemission study begun with the work of Opeil et al. [Phys. Rev. B \textbf{73}, 165109 (2006)], in this paper we report results of an angle-resolved photoemission spectroscopy (ARPES) study performed on a high-quality single-crystal $α$-uranium at 173 K. The absence of surface-reconstruction effects is verified using X-ray Laue and low-energy electron diffraction (LEED) patterns. We compare the ARPES intensity map with first-principles band structure calculations using a generalized gradient approximation (GGA) and we find good correlations with the calculated dispersion of the electronic bands.

description: We study the stability and electronic structure of magic-angle twisted bilayer graphene on the hexagonal boron nitride (TBG/BN). Full relaxation has been performed for commensurate supercells of the heterostructures with different twist angles ($θ'$) and stackings between TBG and BN. We find that the slightly misaligned configuration with $θ' = 0.54^\circ$ and the AA/AA stacking has the globally lowest total energy due to the constructive interference of the moiré interlayer potentials and thus the greatly enhanced relaxation in its $1 \times 1$ commensurate supercell. Gaps are opened at the Fermi level ($E_F$) for small supercells with the stackings that enable strong breaking of the $C_2$ symmetry in the atomic structure of TBG. For large supercells with $θ'$ close to those of the $1 \times 1$ supercells, the broadened flat bands can still be resolved from the spectral functions. The $θ' = 0.54^\circ$ is also identified as a critical angle for the evolution of the electronic structure with $θ'$, at which the energy range of the mini-bands around $E_F$ begins to become narrower with increasing $θ'$ and their gaps from the dispersive bands become wider. The discovered stablest TBG/BN with a finite $θ'$ of about $0.54^\circ$ and its gapped flat bands agree with recent experimental observations.

description: We show that if $T$ is a dependent theory then so is its Keisler randomisation $T^R$. In order to do this we generalise the notion of a Vapnik-Chervonenkis class to families of $[0,1]$-valued functions (a \emph{continuous} Vapnik-Chervonenkis class), and we characterise families of functions having this property via the growth rate of the mean width of an associated family of convex compacts.

description: We report resistivity measurements in the normal state of CeCoIn5 down to 40 mK and simultaneously in magnetic fields up to 9 T in the [001] crystallographic direction and under pressures up to 1.3 GPa. At ambient pressure the data are consistent with a field tuned quantum critical point coincident with the superconducting upper critical field H_{c2}, as observed previously. We find that with increasing pressure the quantum critical point moves inside the superconducting dome to lower fields. Thus, we can rule out that superconductivity is directly responsible for the non-Fermi liquid behavior in CeCoIn5. Instead, the data point toward an antiferromagnetic quantum critical point scenario.

description: In order to constrain the physical processes that regulate and downsize the AGN population, the predictions of the MOdel for the Rise of GAlaxies aNd Active nuclei (MORGANA) are compared to luminosity functions (LFs) of AGNs in the optical, soft X-ray and hard X-ray bands, to the local BH-bulge mass relation, and to the observed X-ray number counts and background. We also give predictions on the accretion rate of AGNs in units of the Eddington rate and on the BH--bulge relation expected at high redshift. We find that it is possible to reproduce the downsizing of AGNs within the hierarchical LambdaCDM cosmogony, and that the most likely responsible for this downsizing is the stellar kinetic feedback that arises in star-forming bulges as a consequence of the high level of turbulence and leads to a massive removal of cold gas in small elliptical galaxies. At the same time, to obtain good fits to the number of bright quasars we need to require that quasar-triggered galactic winds self-limit the accretion onto BHs. In all cases, the predicted BH--bulge relation steepens considerably with respect to the observed one at bulge masses <10^{11} Msun; this problem is related to a known excess in the predicted number of small bulges, common to most similar models, so that the reproduction of the correct number of faint AGNs is done at the cost of underestimating their BH masses. This highlights an insufficient downsizing of elliptical galaxies, and hints for another feedback mechanism able to act on the compact discs that form and soon merge at high redshift. The results of this paper reinforce the need for direct investigations of the feedback mechanisms in active galaxies, that will be possible with the next generation of astronomical telescopes from sub-mm to X-rays.

description: In this experimental study, we report on the mixing properties of interfacial colloidal floaters (glass bubbles) by chemical and hydrodynamical currents generated by self-propelled camphor disks swimming at the air-water interface. Despite reaching a statistically stationary state for the glass bubbles distribution, those floaters always remain only partially mixed. This intermediate state results from a competition between (i) the mixing induced by the disordered motion of many camphor swimmers and (ii) the unmixing promoted by the chemical cloud attached to each individual self-propelled disk. Mixing/unmixing is characterized globally using the standard deviation of concentration and spectra, but also more locally by averaging the concentration field around a swimmer. Besides the demixing process, the system develops a "turbulent-like" concentration spectra, with a large-scale region, an inertial regime and a Batchelor region. We show that unmixing is due to the Marangoni flow around the camphor swimmers, and is associated to compressible effects.

5 Yüksek Riskli EKG Paterni

Publisher: name: Zenodo

description: EKG; her ne kadar sık kullanılan ve yararlılığı tartışmasız bir tanısal test olsa da erken dönemde acile başvuran hastaların yarısına yakınında tanısal yararlılık göstermeyebilir. Bunun yanı sıra EKG’de STEMI olmayan ama AKS açısından yüksek riskli EKG paternleri mevcuttur. Bu paternlerin olduğu hastalarda malign disritmiler, kardiojenik şok, SVO ve ölüm oldukça sık görülmektedir (3). Bu paternlerin bilinmesi ve tanınması, yüksek riskli hastaların seçilebilmesine imkan verir. Aksi durumda ise bu hastalar ya gözden kaçacak (atlanacak) ya da tedavilerini geç alacaklardır ki bu da tedavisinde dakikalarla yarıştığımız AKS hastaları için dramatik sonuçlar yaratacaktır. Amal Mattu, Mathew Macias ve WJ Brady, 2015 yılının sonunda yaptıkları ve AJEM’de yayınlanan çalışmaları ile 5 adet yüksek riskli EKG paterninin önemini ortaya koymuşlardır. Bu paternlerin bazılarından gerek acilci.net’te gerekse başka FOAMed sitelerinde dönem dönem bahsedildi. Bu 5 EKG paternini tek bir yazıda toplayıp, bu paternlerin önemine değinerek, acil doktorlarının konu ile alakalı farkındalığını artırmayı hedefledim. Bu sık rastlanmayan, ancak sadece EKG’ye bakarak yüksek riskli hastaları ayırabileceğimiz paternleri şu şekilde sıralayabiliriz.
Synthetic line and continuum observations of simulated turbulent clouds: the apparent widths of filaments

description: Filamentary structures are ubiquitous in observations of real molecular clouds, and also in simulations of turbulent, self-gravitating gas. However, making comparisons between observations and simulations is complicated by the difficulty of estimating volume-densities observationally. Here, we have post-processed hydrodynamical simulations of a turbulent isothermal molecular cloud, using a full time-dependent chemical network. We have then run radiative transfer models to obtain synthetic line and continuum intensities that can be compared directly with those observed. We find that filaments have a characteristic width of $\,\sim\!0.1 \, {\rm pc}$, both on maps of their true surface density, and on maps of their $850 \, {\rm μm}$ dust-continuum emission, in agreement with previous work. On maps of line emission from CO isotopologues, the apparent widths of filaments are typically several times larger because the line intensities are poorly correlated with the surface density. On maps of line emission from dense-gas tracers such as N$_2$H$^+$ and HCN, the apparent widths of filaments are $\lesssim 0.1 \, {\rm pc}$. Thus, current observations of molecular-line emission are compatible with the universal $0.1 \, {\rm pc}$ filament width inferred from ${\it Herschel}$ observations, provided proper account is taken of abundance, optical-depth, and excitation considerations. We find evidence for $\sim 0.4 \, {\rm km \, s^{-1}}$ radial velocity differences across filaments. These radial velocity differences might be a useful indicator of the mechanism by which a filament has formed or is forming, for example the turbulent cloud scenario modelled here, as against other mechanisms such as cloud-cloud collisions.
