description: The use of cryogenic silicon as a detector medium for dark matter searches is gaining popularity. Many of these searches are highly dependent on the value of the photoelectric absorption cross section of silicon at low temperatures, particularly near the silicon band gap energy, where the searches are most sensitive to low mass dark matter candidates. While such cross section data has been lacking from the literature, previous dark matter search experiments have attempted to estimate this parameter by extrapolating it from higher temperature data. However, discrepancies in the high temperature data have led to order-of-magnitude differences in the extrapolations. In this paper, we resolve these discrepancies by using a novel technique to make a direct, low temperature measurement of the photoelectric absorption cross section of silicon at energies near the band gap.

description: A tree-level flavor changing neutral current in the up-like quark sector appears in one of the variations of the Littlest Higgs model. We investigate the effects of this coupling in the D+ -> pi+ l+ l- and D0 -> rho0 l+ l- decays, which are the most appropriate candidates for the experimental studies. However, the effects are found to be too small to be observed in the current and the foreseen experimental facilities. These decays are still dominated by the standard model long-distance contributions, which are reevaluated based on the new experimental input.

description: New qualitative picture of vortex length-scale dependence has been found in recent electrical transport measurements performed on strongly anisotropic BSCCO single crystals in zero magnetic field. This indicates the need for a better description of the 3D/2D crossover in vortex dimensionality. The vortex-dominated properties of high transition temperature superconductors with extremely high anisotropy (layered systems) are reasonably well described in the framework of the layered XY model which can be mapped onto the layered sine-Gordon model. For the latter we derive an exact renormalization group (RG) equation using Wegner's and Houghton's approach in the local potential approximation. The agreement of the UV scaling laws find by us by linearizing the RG equations with those obtained previously in the literature in the dilute gas approximation makes the improvement appearant which can be achieved by solving our RG equations numerically.

Publisher: name: Zenodo
Year: 2021

description: Drought is a major environmental constraint affecting the growth and production of coffee. Selection of drought-tolerant Arabica coffee genotypes an important way to mitigate climate change impacts on coffee production. A Study was conducted at Awada research sub-center in Sidama zone of south Ethiopia (6045’ N, 380 38’E and 1740 m.a.s.l) with the objective to screening drought-tolerant Sidamo coffee genotypes. The experiment was conducted during 2011/12 and 2013 under a controlled condition in a rain shelter; it was laid down in a RCBD with three replications. Fourteen Sidamo coffee genotypes were subjected to two watering regimes: water-stressed and well-watered for 28 days. The genotypes were also evaluated under field conditions during 2014 season at Korkie sub-station which is located 20 km south of Awada (6034 N, 38039’E and 1800masl). Results of the experiment indicated that there was high significant difference among the genotypes for extent of wilting, total dry matter, relative leaf water content and leaf retention capacity. C85238 shows high drought stress resistance with 1.58 scale value while c9744 indicated as sensitive to drought stress with 2.99 scale value.c9722 obtained the highest value 11.76 gram in total dry matter, c85237 obtained the highest leaf retention capacity 51.28% and c85257 obtained the maximum relative leaf water content. Significant difference was also observed in root to shoot ratio and stomatal conductance, with highest values obtained by c974 and c75227 respectively The field evaluation indicated that plant height, canopy diameter, coffee yield and number of primary branch were significantlyinfluenced at P<0.01 and number of bearing branches and leaf turgid weight were influenced by the genotypes at P<0.05 with c9722 scored maximum value 288.9 cm plant height, 76 NBB, 163.43 cm CD and 11.76 qt/ha coffee yield. There was strong correlation observed between extent of wilting scored at seedling stage and grain yield at field conditions of genotypes (r = -0.80). Therefore from all the three-year evaluations c979, c974, c85238 c9722, c75277 and c1377 performed better in resistingdrought under both field and controlled conditions.

description: We quantify how well matrix product states approximate exact ground states of 1-D quantum spin systems as a function of the number of spins and the entropy of blocks of spins. We also investigate the convex set of local reduced density operators of translational invariant systems. The results give a theoretical justification for the high accuracy of renormalization group algorithms, and justifies their use even in the case of critical systems.

description: We introduce the use of deep learning ensembles for real-time, gravitational wave detection of spinning binary black hole mergers. This analysis consists of training independent neural networks that simultaneously process strain data from multiple detectors. The output of these networks is then combined and processed to identify significant noise triggers. We have applied this methodology in O2 and O3 data finding that deep learning ensembles clearly identify binary black hole mergers in open source data available at the Gravitational-Wave Open Science Center. We have also benchmarked the performance of this new methodology by processing 200 hours of open source, advanced LIGO noise from August 2017. Our findings indicate that our approach identifies real gravitational wave sources in advanced LIGO data with a false positive rate of 1 misclassification for every 2.7 days of searched data. A follow up of these misclassifications identified them as glitches. Our deep learning ensemble represents the first class of neural network classifiers that are trained with millions of modeled waveforms that describe quasi-circular, spinning, non-precessing, binary black hole mergers. Once fully trained, our deep learning ensemble processes advanced LIGO strain data faster than real-time using 4 NVIDIA V100 GPUs.

description: A smoking gun signature for a first-order phase transition with negative speed of sound squared $c_s^2$ is the occurrence of a spinodal instability. In the gauge/gravity duality it corresponds to a Gregory-Laflamme type instability, which can be numerically simulated as the evolution of unstable planar black branes. Making use of holography its dynamics is studied far from and near a critical point with the following results. Near a critical point the interface between cold and hot stable phases, given by its width and surface tension, is found to feature a wider phase separation and a smaller surface tension. Far away from a critical point the formation time of the spinodal instability is reduced. Across softer and harder phase transitions, it is demonstrated that mergers of equilibrated peaks and unstable plateaux lead to the preferred final single phase separated solution. Finally, a new atypical setup with dissipation of a peak into a plateau is discovered. In order to distinguish the inhomogeneous states I propose a new criterium based on the maximum of the transverse pressure at the interface which encodes phase-mixed peaks versus fully phase separated plateaux.

Gemini and Hubble Space Telescope Evidence for an Intermediate Mass Black Hole in omega Centauri

description: The globular cluster omega Centauri is one of the largest and most massive members of the galactic system. However, its classification as a globular cluster has been challenged making it a candidate for being the stripped core of an accreted dwarf galaxy; this together with the fact that it has one of the largest velocity dispersions for star clusters in our galaxy makes it an interesting candidate for harboring an intermediate mass black hole. We measure the surface brightness profile from integrated light on an HST}/ACS image of the center, and find a central power-law cusp of logarithmic slope -0.08. We also analyze Gemini GMOS-IFU kinematic data for a 5x5 arcsec field centered on the nucleus of the cluster, as well as for a field 14 arcsecaway. We detect a clear rise in the velocity dispersion from 18.6 km/s at 14 arcsec to 23 km/s in the center. A rise in the velocity dispersion could be due to a central black hole, a central concentration of stellar remnants, or a central orbital structure that is radially biased. We discuss each of these possibilities. An isotropic, spherical dynamical model implies a black hole mass of 4.0^{+0.75}_{-1.0} times 10^4 M_sun, and excludes the no black hole case at greater than 99% significance. We have also run flattened, orbit-based models and find similar results. While our preferred model is the existence of a central black hole, detailed numerical simulations are required to confidently rule out the other possibilities.

description: Tailored time-dependent variations of the transverse profile together with longitudinal phase shifts of laser beams are studied. It is shown theoretically that a standing wave setup and real-time beam forming techniques (e.g. by computer-addressed holograms) should make it possible to implement smooth transport across and along the beams employed in optical trapping schemes. Novel modes for the efficient collection, transport, and concentration of trapped particles should thus become realizable in optical trapping setups.

Pharmacist-client communication : a study of quality and client satisfaction
Creators: name: Paluck, Elan Carla Marie
Publisher: name: University of British Columbia
Year: 2009

description: OBJECTIVE OF STUDY: The objective of the study was to examine the quality of interactions occurring between pharmacists and clients, the facilitators and barriers shaping the way pharmacists communicate with clients, and the use of client satisfaction ratings as an outcome measure for pharmacist-client communication. METHODS AND MEASURES: Verbal exchanges between consenting pharmacists (n=100) and clients (n=786) were audio-recorded during four-hour, on-site, observation periods. Clients rated their interaction with the pharmacist using an 11-item Client Satisfaction Rating instrument, while pharmacists completed a questionnaire examining the factors predisposing, enabling, and reinforcing their communication with clients. Subsequent to data collection, an expert panel listened to the audiotapes and rated the quality of the interactions using a 9-item Quality of Communication rating scale. FINDINGS: The mean overall expert rating for the pharmacist-client interactions was 4.0 (out of 7), and represented a "satisfactory" rating. Hierarchical multiple regression analysis revealed that the predisposing, enabling and reinforcing variables measured in the Pharmacists' Questionnaire accounted for 19% of the variance in pharmacists' technical quality scores. Client satisfaction ratings and expert ratings of communication quality were modestly correlated (r=0.14; p<0.001). CONCLUSIONS: While the 60% of consultations in this study met or exceeded the mandated communication requirements of pharmacy practice, pharmacists were uniformly weakest in their client assessment skills and in their discussions of medication precautions and non-pharmacologic approaches to symptom management. Most pharmacists in the study reported being highly predisposed to communicating with their clients, but many lacked the reinforcing factors, and to a lesser degree, enabling factors that are considered necessary to sustain quality communication in the workplace. Client satisfaction ratings were positively skewed with little variability, making it difficult to detect a relationship between the expert and client ratings. Reasons why the study was unable to capture more of the variance in its proposed relationships are provided, as well as areas for future research.

description: We present the host galaxy molecular gas properties of a sample of 213 nearby (0.0110^44 erg/s) increases by ~10-100 between a molecular gas mass of 10^8.7 Msun and 10^10.2 Msun. Higher Eddington ratio AGN galaxies tend to have higher molecular gas masses and gas fractions. Higher column density AGN galaxies (Log NH>23.4) are associated with lower depletion timescales and may prefer hosts with more gas centrally concentrated in the bulge that may be more prone to quenching than galaxy wide molecular gas. The significant average link of host galaxy molecular gas supply to SMBH growth may naturally lead to the general correlations found between SMBHs and their host galaxies, such as the correlations between SMBH mass and bulge properties and the redshift evolution of star formation and SMBH growth.

description: Political art and theater have recently experienced significant blooming periods in the U.S. and U.K. In context of the so-called "War on Terror" artists – especially in the theater world – produced projects and performances that partly line up with internationally relevant theory-driven developments and partly draw from largely discredited models of political theater. Jenny Spencer's Political and Protest Theatre after 9/11 – Patriotic Dissent brings together essays by key scholars and theorist-practitioners in the field, which offer the so far most comprehensive view on the decidedly significant moments in British and American theater history. Sara Brady's Performance, Politics, and the War on Terror – "Whatever it Takes" explores the role of performance in the "War on Terror" in all its complexity, covering both the performance of politics and politicians as well as various approaches to and instances of political performance in the aesthetic realm.

description: We present parallaxes, proper motions, and $J$-band photometry for 348 L and T dwarfs measured using the wide-field near-infrared camera WFCAM on the United Kingdom Infrared Telescope. This is the largest single batch of infrared parallaxes for brown dwarfs to date. Our parallaxes have a median uncertainty of 3.5 mas, similar to most previous ground-based infrared parallax surveys. Our target list was designed to complete a volume-limited parallax sample of L0-T8 dwarfs out to 25 pc spanning declinations $-30^\circ$ to $+60^\circ$ (68% of the sky). We report the first parallaxes for 165 objects, and we improve on previous measurements for another 53 objects. Our targets include 104 objects (mostly early-L dwarfs) having $Gaia$ DR2 parallax measurements, with which our parallaxes are consistent. We include an extensive comparison of previous literature parallaxes for L and T dwarfs with both our results and $Gaia$ DR2 measurements, identifying systematic offsets for some previous surveys. Our parallaxes confirm that 14 objects previously identified as wide common proper motion companions to main-sequence stars have distances consistent with companionship. We also report new $J_\mathrm{MKO}$ photometry for our targets, including the first measurements for 193 of our targets and improvements over previously published $J_\mathrm{MKO}$ photometry for another 60 targets. Altogether, our parallaxes will enable the first population studies using a volume-limited sample spanning spectral types L0-T8 defined entirely by parallaxes.

description: We extend the recently proposed Black Hole Entropy Distance Conjecture to the case of charged black holes in de Sitter space. By systematically studying distances in the space of black hole geometries with multiple horizons, we find that the distance is generically related to the logarithm of the entropy. From the infinite distance conjecture this predicts the appearance of a massless tower of modes in the limit of infinite entropy. Further, we study the evaporation of these black holes and relate it to the geometric distance. We find that the corresponding distance to the final stage of evaporation is finite. We conclude that evaporation does not lead to the appearance of a light tower of black hole microstates.

Treatment of mood disorder in an at-risk sample of high school adolescents: a randomized trial of art therapy intervention

description: Although a vast scope of literature has investigated the efficacy of other treatments of depression there remains a gap in the research of creative arts modalities as treatment for depression. The following research study will address this oversight providing new information on the efficacy of short-term art therapy as treatment for depression in the adolescent population. In the following study high school counselors and other helping professionals identified high school adolescents at risk for future depressive disorder by virtue of having elevated depressive symptomology. The study then compared two randomly assigned individual or group art therapy treatment groups to a wait-list control group. The Children's Depression Inventory, Stony Brook Child Psychiatric Checklist, and the Children's Behavior Inventory assessments were administered pre- and post-treatment for all three groups. Quantitative statistical analysis was used to determine the effectiveness of individual or group art therapy intervention vs. the non-intervention control group. Results seem to show that the individual art therapy treatment group when compared to themselves after treatment displayed a significant decrease in depressive symptoms according to the Children's Depression Inventory [t(df=3)=2.87, p=0.03] and the Child Behavior Checklist [t(df=3)=3.33, p =0.02]. Those receiving group art therapy treatment seemed to show significant improvement according to the Children's Depression Inventory [t(df=4)=2.39, p=0.04] when compared to themselves after treatment. The Control Group results indicate there was no significant difference in the scores on any of the three psychological measures. Between group analysis indicates the individual treatment group showed a decrease in psychiatric symptoms (p=.04) compared to the control group. In light of the many between group differences it is the researcher contention that a larger sample size may result in stronger effects. The post-treatment comparison of the combined treatment groups to the control group indicates significantly fewer parent-reported behavior problems and social incompetencies (p=.01) as well as psychiatric symptoms (p=.02). Based on these results it is concluded that individual and group art therapy are effective in relieving symptoms of depression in youth compared to no treatment, with individual art therapy appearing to be more effective than group art therapy.

We show that a superfluid where the translational symmetry is broken by a finite Cooper pair momentum, namely an FFLO-type state, minimizes the Helmholtz free energy of the system. We demonstrate that such a state is clearly visible in the observable momentum distribution of the atoms, and analyze the dependence of the order parameter and the momentum distribution on the filling fraction and the interaction strength.

description: A multi-orbital model for a CoO_2-layer in Na_xCoO_2 is derived. In this model the kinetic energy for the degenerate t_2g-orbitals is given by indirect hopping over oxygen, leading naturally to the concept of four inter-penetrating Kagome lattices. Local Coulomb interaction couples the four lattices and an effective Hamiltonian for the interaction in the top band can be written in terms of fermionic operators with four different flavors. Focusing on charge and spin density instabilities, a big variety of possible metallic states with spontaneously broken symmetry are found. These states lead to different charge, orbital, spin and angular momentum ordering patterns. The strong superstructure formation at x=0.5 is also discussed within this model.

description: We address joint photodetection as a method to discriminate between the classical correlations of a thermal beam divided by a beam splitter and the quantum entanglement of a twin-beam obtained by parametric downconversion. We show that for intense beams of light the detection of the difference photocurrent may be used, in principle, in order to reveal entanglement, while the simple measurement of the correlation coefficient is not sufficient. We have experimentally measured the correlation coefficient and the variance of the difference photocurrent on several classical and quantum states. Results are in good agreement with theoretical predictions taking into account the extra noise in the generated fields that is due to the pump-laser fluctuations.

description: We present a package for FeynRules which derives the Feynman rules for the Standard Model Effective Field Theory up to dimension-six using the background field method for gauge fixing. The package includes operators which shift the kinetic and mass terms of the Lagrangian up to dimension-eight and including dimension-six squared effects consistently. To the best of the author's knowledge this is the first publicly available package to include dimension-six squared effects consistently. The package is validated in a partner publication by analyzing the Ward Identities at dimension-six and one-loop order. We also extend the partner work in this article by including the dimension-six squared effects further demonstrating the consistency of their implementation. In doing so we find that failure to consistently include field shifts to dimension-six squared causes a breakdown in the Ward identities implying concerns about many calculations in the literature which do not properly incorporate these effects. The FeynRules files, as well as Mathematica notebooks performing the relevant calculations, can be downloaded from the FeynRules website and are included as ancillary files to this publication.

Subjects: subject: Neural and Evolutionary Computing (cs.NE)
subject: FOS: Computer and information sciences

description: We posit a new paradigm for image information processing. For the last 25 years, this task was usually approached in the frame of Treisman's two-stage paradigm [1]. The latter supposes an unsupervised, bottom-up directed process of preliminary information pieces gathering at the lower processing stages and a supervised, top-down directed process of information pieces binding and grouping at the higher stages. It is acknowledged that these sub-processes interact and intervene between them in a tricky and a complicated manner. Notwithstanding the prevalence of this paradigm in biological and computer vision, we nevertheless propose to replace it with a new one, which we would like to designate as a two-part paradigm. In it, information contained in an image is initially extracted in an independent top-down manner by one part of the system, and then it is examined and interpreted by another, separate system part. We argue that the new paradigm seems to be more plausible than its forerunner. We provide evidence from human attention vision studies and insights of Kolmogorov's complexity theory to support our arguments. We also provide some reasons in favor of separate image interpretation issues.

description: We obtain closed-form solutions of several inhomogeneous Lienard equations by the factorization method. The two factorization conditions involved in the method are turned into a system of first-order differential equations containing the forcing term. In this way, one can find the forcing terms that lead to integrable cases. Because of the reduction of order feature of factorization, the solutions are simultaneously solutions of first-order differential equations with polynomial nonlinearities. The illustrative examples of Lienard solutions obtained in this way generically have rational parts, and consequently display singularities.

description: We suggest a few particle physics processes in which excited 2p pionium $\mathrm{A}^\prime_{2π}$ may be observed. They include the $e^+e^-\toπ^+π^-$ annihilation, the $V^0\toπ^0\ell^+\ell^-$ and $K^\pm\toπ^\pm\ell^+\ell^-$ ($\ell=e,μ$) decays, and the photoproduction of two neutral pions from nucleons. We analyze available experimental data and find that they, in some cases, indicate the presence of 2p pionium, but do not provide definite proof.

Predicting coexistence in experimental ecological communities

description: Experimental ecological communities are important tools for exploring the processes that promote and maintain biodiversity. Communities assembled in controlled conditions afford much greater ease of manipulation, compared to field-based systems, allowing for the construction of multispecies communities of varying composition. Predicting the outcomes of species interactions in such complex communities remains challenging, however, largely due to the difficulty of identifying and parameterizing dynamical models.

In many cases, the goal of parameterizing dynamical models is not to predict dynamics per se, but rather to make some inference about an outcome of the system, such as long-term diversity, coexistence, stability, or invasibility. Modeling complete dynamics is often seen as a necessary first step to characterizing these properties. But given the challenges inherent in fitting dynamical models, and the ease of manipulating and quantifying (e.g. via high-throughput sequencing) experimental communities with high replication, we ask whether data only from experimental endpoints is sufficient to predict unobserved community outcomes. In particular, we introduce a novel yet straightforward statistical approach to predicting coexistence and species abundances in experimental ecological communities, using only endpoint data. This approach obviates the need for expensive time-series, instead leveraging the tractability of small experimental communities.

We consider many communities drawn from a pool of n species. Given the endpoint abundances of some of these communities, can we predict the abundances in unobserved ones? We approach this problem by directly relating endpoint abundances, using a simple statistical model that is agnostic to the true dynamical model underpinning the system. We examine three independent datasets - a plant system, a protist system, and an algae-Daphniidae system - to test the efficacy and robustness of our method.

Crucially, because our model requires relatively little data to fit, we are able to test its predictions against experimental outcomes not used for fitting. Foregoing dynamics, we are able to predict out-of-fit endpoints with high accuracy (R2 = 0.98, 0.94, 0.92 for predicted vs. observed in each system, respectively). Additionally, we show that our method can offer insights into stability, invasibility, and extinction. Finally, our method suggests new principles for the design of efficient competition experiments. Taken together, our results indicate that endpoint data can be surprisingly informative about the structure of ecological communities, and can suggest a principled way to assemble large experimental communities, helping ecologists probe the mechanisms that promote coexistence in natural and synthetic ecosystems.

description: We explore conformal primary wavefunctions for all half integer spins up to the graviton. Half steps are related by supersymmetry, integer steps by the classical double copy. The main results are as follows: we 1) introduce a convenient spin frame and null tetrad to organize all radiative modes of varying spin; 2) identify the massless spin-3/2 conformal primary wavefunction as well as the conformally soft Goldstone mode corresponding to large supersymmetry transformations; 3) indicate how to express a conformal primary of arbitrary spin in terms of differential operators acting on a scalar primary; 4) demonstrate that conformal primary metrics satisfy the double copy in a variety of forms -- operator, Weyl, and Kerr-Schild -- and are exact, albeit complex, solutions to the fully non-linear Einstein equations of Petrov type N; 5) propose a novel generalization of conformal primary wavefunctions; and 6) show that this generalization includes a large class of physically interesting metrics corresponding to ultra-boosted black holes, shockwaves and more.

description: Гидроксид кальция уже много лет успешно используется при лечении корневых каналов. Однако при случайном попадании в окружающие жизненно важные структуры она может нанести серьезный вред, привести к тромбозу, если попадет в кровеносные сосуды, повредить соединительную ткань и вызвать некроз кожи. Эти побочные реакции известны как синдром Николау (СН) или лекарственная эмболия (embolia cutis medicamentosa). О таких побочных эффектах введения гидроксида кальция за верхушку во время лечения корневых каналов было опубликовано очень мало сообщений. 16-летняя пациентка была направлена в эндодонтическое отделение в клинику Ташкентской Медицинской Академии для обследования после лечения в отделении челюстно-лицевой хирургии по поводу отека и некроза тканей, возникших после эндодонтического лечения в другой клинике.

description: We present analytic expressions to evaluate at O(alpha) the effects of soft-photon emission, and the related virtual corrections, in non-leptonic decays of the type B,D -> P1 P2, where P1 and P2 are scalar or pseudoscalar particles. The phenomenological implications of these results are briefly discussed. For B decays into charged pions the effects of soft-photon emission are quite large: the corrections to the rates can easily exceed the 5% level if tight cuts on the photon energy are applied.

Non-Clausius heat transfer: The method of the nonstationary Langevin equation

description: Compared to other formulations of the second law of thermodynamics, the Clausius statement that heat does not spontaneously flow from cold to hot concerns a system in non-equilibrium states, and in that respect is more ambitious but also more ambiguous. We discuss two scenarios when the Clausius statement in its plain form does not hold. First, for ergodic systems, the energy transfer may be consistent with the statement on a coarse-grained time scale, but be anomalously directed during time intervals shorter than the thermalization time. In particular, when an initially colder system is brought in contact to a hotter bath, the internal energy of the former increases with time in a long run but not monotonically. Second, the heat transfer may not respect the Clausius statement on any time-scale in non-ergodic systems due to the formation of localized vibrational modes. We illustrate the two scenarios with a familiar model of an isotope atom attached to a semi-infinite harmonic atomic chain. Technically, the discussion is based on a Langevin equation for the isotope, using the initial condition when the isotope and chain are initially prepared in uncorrelated canonical states under the constraint that the boundary atom between the isotope and chain is initially fixed and later released. In such setting, the noise in the Langevin equation is non-stationary, and the fluctuation-dissipation relation has a non-standard form.

description: We develop a phenomenological theory of pulse induced phase transformations behind the SET (from high to low resistive state) and RESET (backward) processes in nonvolatile memory. We show that in modern era devices, both evolve in the adiabatic regime with energy deposition time much shorter than that of thermalization. They are however different by the operating modes: voltage source driven for SET and current source driven for RESET. The characteristic temperatures and transition rates are expressed through material and process parameters.

Connecting cosmological accretion to strong Lyman-alpha absorbers

description: We present an analytical model for the cosmological accretion of gas onto dark matter halos, based on a similarity solution applicable to spherical systems. Performing simplified radiative transfer, we compute how the accreting gas turns increasingly neutral as it self-shields from the ionising background, and obtain the column density, $N_{\rm HI}$, as a function of impact parameter. The resulting column-density distribution function (CDDF) is in excellent agreement with observations. The analytical expression elucidates (1) why halos over a large range in mass contribute about equally to the CDDF as well as (2) why the CDDF evolves so little with redshift in the range $z=2\rightarrow 5$. We show that the model also predicts reasonable DLA line-widths ($v_{90}$), bias and molecular fractions. Integrating over the CDDF yields the mass density in neutral gas, $Ω_{\rm HI}$, which agrees well with observations. $Ω_{\rm HI}(z)$ is nearly constant even though the accretion rate onto halos evolves. We show that this occurs because the fraction of time that the inflowing gas is neutral depends on the dynamical time of the halo, which is inversely proportional to the accretion rate. Encapsulating results from cosmological simulations, the simple model shows that most Lyman-limit system and damped Lyman-alpha absorbers are associated with the cosmological accretion of gas onto halos.
