description: We discuss a series of thermodynamic, magnetic and electrical transport experiments on the two heavy fermion compounds CeNi2Ge2 and YbRh2Si2 in which magnetic fields, B, are used to tune the systems from a Non-Fermi liquid (NFL) into a field-induced FL state. Upon approaching the quantum-critical points from the FL side by reducing B we analyze the heavy quasiparticle (QP) mass and QP-QP scattering cross sections. For CeNi2Ge2 the observed behavior agrees well with the predictions of the spin-density wave (SDW) scenario for three-dimensional (3D) critical spin-fluctuations. By contrast, the observed singularity in YbRh2Si2 cannot be explained by the itinerant SDW theory for neither 3D nor 2D critical spinfluctuations. Furthermore, we investigate the magnetization M(B) at high magnetic fields. For CeNi2Ge2 a metamagnetic transition is observed at 43 T, whereas for YbRh2Si2 a kink-like anomaly occurs at 10 T in M vs B (applied along the easy basal plane) above which the heavy fermion state is completely suppressed.

The apparent anti-correlation between the mass opacity of interstellar dust and the surface-density of interstellar gas

description: Recent analyses of ${\it Herschel}$ observations suggest that in nearby disc galaxies the dust mass opacity at $500 \, {\rm μm}$, $κ_{500}$, decreases with increasing gas surface density, $Σ_{\rm ISM}$ (Clark et al. 2019). This apparent anti-correlation between $κ_{500}$ and $Σ_{\rm ISM}$ is opposite to the behaviour expected from theoretical dust evolution models; in such models, dust in denser, cooler regions (i.e. regions of increased $Σ_{\rm ISM}$) tends to grow and therefore to have increased $κ_{500}$. We show, using a toy model, that the presence of a range of dust temperatures along the line of sight can lead to spuriously low estimated values of $κ_{500}$. If in regions of higher $Σ_{\rm ISM}$ the range of dust temperatures extends to lower values (as seems likely), the magnitude of this effect may be sufficient to explain the apparent anti-correlation between $κ_{500}$ and $Σ_{\rm ISM}$. Therefore there may not be any need for spatial variation in the intrinsic dust properties that run counter to theoretical expectations.

description: Looking for bright galaxies born in the early universe is fundamental to investigating the Epoch of Reionization, the era when the first stars and galaxies ionized the intergalactic medium. We utilize Hubble Space Telescope pure parallel imaging to select galaxy candidates at a time 500 to 650 million years after the Big Bang, which corresponds to redshifts z ~ 8-10. These data come from the Brightest of Reionizing Galaxies Survey (BoRG) Cycle 22 dataset, which consists of pure-parallel imaging in ~ 90 different lines of sight that sum up to an area of ~ 420 arcmin^2. This survey uses five filters and has the advantage (compared to the Cycle 21 BoRG program) of including imaging in the JH140 band, covering continuous wavelengths from the visible to near-infrared (lambda = 0.35um - 1.7um). This allows us to perform reliable selection of galaxies at z>8 using the photometric redshift technique. We use these galaxy candidates to constrain the bright end of the rest-frame ultraviolet luminosity function in this epoch. These candidates are excellent targets for follow-up observations, particularly with the James Webb Space Telescope.

description: Even though quantum chromodynamics is a broken conformal theory, the AdS/CFT correspondence has led to important insights into the properties of QCD. For example, as shown by Polchinski and Strassler, dimensional counting rules for the power-law falloff of hadron scattering amplitudes follow from dual holographic models with conformal behavior at short distances and confinement at large distances. We find that one also obtains a remarkable representation of the entire light-quark meson and baryon spectrum, including all orbital excitations, based on only one mass parameter. We also show how hadron light-front wavefunctions and hadron form factors in both the space-like and time-like regions can be predicted.

description: The recent coronavirus pandemic follows in its early stages an almost exponential growth, with the number of cases quite well fit in time by $N(t)\propto e^{αt}$, in many countries. We analyze the rate $α$ for each country, starting from a threshold of 30 total cases and using the next 12 days, capturing thus the early growth homogeneously. We look for a link between $α$ and the average temperature $T$ of each country, in the month of the epidemic growth. We analyze a {\it base} set of 42 countries, which developed the epidemic earlier, an {\it intermediate} set of 88 countries and an {\it extended} set of 125 countries, which developed the epidemic more recently. Applying a linear fit $α(T)$, we find increasing evidence for a decreasing $α$ as a function of $T$, at $99.66\%$C.L., $99.86\%$C.L. and $99.99995 \%$ C.L. ($p$-value $5 \cdot 10^{-7}$, or 5$σ$ detection) in the {\it base}, {\it intermediate} and {\it extended} dataset, respectively. The doubling time is expected to increase by $40\%\sim 50\%$, going from $5^\circ$ C to $25^\circ$ C. In the {\it base} set, going beyond a linear model, a peak at $(7.7\pm 3.6)^\circ C$ seems to be present, but its evidence disappears for the larger datasets. We also analyzed a possible bias: poor countries, often located in warm regions, might have less intense testing. By excluding countries below a given GDP per capita, we find that our conclusions are only slightly affected and only for the {\it extended} dataset. The significance remains high, with a $p$-value of $10^{-3}-10^{-4}$ or less. Our findings give hope that, for northern hemisphere countries, the growth rate should significantly decrease as a result of both warmer weather and lockdown policies. In general the propagation should be hopefully stopped by strong lockdown, testing and tracking policies, before the arrival of the cold season.

title: Requirements-Driven Adaptation of Choreographed Interactions
Creators: name: Mahfouz, Ayman
Publisher: name: The Open University
Year: 2012

description: Electronic services are emerging as the de-facto enabler of interaction interoperability across organization boundaries. Cross-organizational interactions are often “choreographed”, i.e. specified by a messaging protocol from a global point of view independent of the local view of each interacting organization. Local requirements motivating an interaction as well as the global contextual requirements governing the interaction inevitably evolve over time, requiring adaptation of the corresponding interaction protocol. Adaptation of an interaction protocol must ensure the satisfaction of both sets of interaction requirements while maintaining consistency between the global view and the local views of an interaction specification. Such adaptation is not possible with the current state-of-the-art representations of choreographed interactions, as they capture only operational messaging specifications detached from both local organizational requirements as well as global contextual requirements. This thesis presents three novel contributions that tackle adaptation of choreographed interaction protocols: an automated technique for deriving an interaction protocol from requirements, a formalization of consistency between local and global views, and a framework for guiding the adaptation of a choreographed interaction. A choreographed interaction is specified using models of organizational requirements motivating the interaction. We employ the formal semantics embedded in requirements models to automatically derive an interaction protocol. We propose a framework for relating the global and local views of interaction specification and maintaining consistency between them. We develop a metamodel for interaction specification, from which we enumerate adaptation operations. We build a catalogue that provides guidance on performing each operation and propagating changes between the global and local views. These contributions are evaluated using examples from the literature as well as a real-world case study.

 ETYMOLOGY. — Iziko is the network of South African museums, which includes the South African Museum where most of the specimens studied here are stored, Ziphius is a Recent ziphiid genus. Gender masculine.
 DIAGNOSIS. — Izikoziphius n. gen. differs from all the other members of the Ziphiinae in the presence of a fossa on the anterior surface of the ascending process of the premaxilla distinct from the premaxillary sac fossa. It differs from Ziphius in: longer rostrum; lack of a prenarial basin; lesser asymmetry of the premaxillary sac fossae (<0.40) and longer contact between nasal and premaxillary crest. It differs from Tusciziphius in: the barely concave premaxillary sac fossa and the anterior part of the nasal not contacting the premaxillary crest. It differs from Choneziphius in: longer rostrum; premaxillae medially separated on the rostrum by the thickened vomer and barely concave premaxillary sac fossa. It differs from Caviziphius in: premaxillae medially separated on the rostrum by the thickened vomer; lower rostrum base and less asymmetric and barely concave premaxillary sac fossa. It differs from Aporotus, Beneziphius, Messapicetus, and Ziphirostrum in: longitudinally elongated nasals; premaxillae medially separated on the rostrum by the thickened vomer and lack of a constriction of the ascending process of the premaxilla (last character less clearly present in Messapicetus). Both species of Izikoziphius n. gen. have a somewhat smaller cranium size than Ziphius cavirostris.

description: Synchronization occurs ubiquitously in nature. The van der Pol oscillator has been a favorite model to investigate synchronization. Here we study the oscillator in the deep quantum regime, where nonclassical effects dominate the dynamics. Our results show: (i) squeezed driving loses its effect, (ii) noise boosts synchronization, (iii) synchronization is bounded, and (iv) the limit-cycle is insensitive to strong driving. We propose a synchronization measure and analytically calculate it. These results reflect intrinsic differences between synchronization in the quantum and deep quantum regimes.

description: This deliverable outlines the CLEARING HOUSE typology of urban forests as nature-based solutions (UF-NBS). The typology thus conceptualizes entities relevant to UF-NBS. To do so, elements of green-blue infrastructure (GBI) are defined in the typology. Contrary to purely textual representations of knowledge, CLEARING HOUSE proposes a definition of GBI elements through traits, i.e., characteristic and defining morphological, physical, functional, and institutional attributes, including for example the composition, spatial grouping, and topology of UF-NBS elements, and the ecosystem services and benefits provided them. CLEARING HOUSE proposes a semantic approach to express this knowledge, i.e., a formalization of knowledge as an ontology using the Web Ontology Language. Such ontologies are machine-interpretable series of statements of facts to define a taxonomy (a vocabulary). The definitions of GBI elements are embedded within a formalization of overarching concepts, particularly, of urban forest, nature-based solutions (NBS), and of UF-NBS. Here, urban forest is conceptually understood as the entirety of trees within an urban-ecological system. NBS are perceived in CLEARING HOUSE as an overarching concept that embraces natural and semi-natural elements of the GBI such as forests, engineered solutions such as permeable pavements, as well as actions inspired by nature. UF-NBS are then conceptualized as the intersection of the two previous entities, i.e., as the intersection of urban forest and NBS, and thus include any tree-related NBS. The proposed typology will provide the grounding knowledge of the comparative case study analysis to be conducted by CLEARING HOUSE, and will serve as a basis for the development of the CLEARING HOUSE benchmarking tool.

description: We study equilibrium and nonequilibrium properties of the single-impurity Anderson model with a power-law pseudogap in the density of states. In equilibrium, the model is known to display a quantum phase transition from a generalized Kondo to a local moment phase. In the present work, we focus on the extension of these phases beyond equilibrium, i.e. under the influence of a bias voltage. Within the auxiliary master equation approach combined with a scheme based on matrix product states (MPS) we are able to directly address the current-carrying steady state. Starting with the equilibrium situation, we first corroborate our results by comparing with a direct numerical evaluation of ground state spectral properties of the system by MPS. Here, a scheme to locate the phase boundary by extrapolating the power-law exponent of the self energy produces a very good agreement with previous results obtained by the numerical renormalization group. Our nonequilibrium study as a function of the applied bias voltage is then carried out for two points on either side of the phase boundary. In the Kondo regime the resonance in the spectral function is splitted as a function of the increasing bias voltage. The local moment regime, instead, displays a dip in the spectrum near the position of the chemical potentials. Similar features are observed in the corresponding self energies. The Kondo split peaks approximately obey a power-law behavior as a function of frequency, whose exponents depend only slightly on voltage. Finally, the differential conductance in the Kondo regime shows a peculiar maximum at finite voltages, whose height, however, is below the accuracy level.

description: We have investigated magnetic properties of Rb$_2$Cu$_2$Mo$_3$O$_{12}$ powder. Temperature dependence of magnetic susceptibility and magnetic-field dependence of magnetization have shown that this cuprate is a model compound of a one-dimensional spin-1/2 Heisenberg system with ferromagnetic first-nearest-neighbor (1NN) and antiferromagnetic second-nearest-neighbor (2NN) competing interactions (competing system). Values of the 1NN and 2NN interactions are estimated as $J_1 = -138$ K and $J_2 = 51$ K ($α\equiv J_2 / J_1 = -0.37$). This value of $α$ suggests that the ground state is a spin-singlet incommensurate state. In spite of relatively large $J_1$ and $J_2$, no magnetic phase transition appears down to 2 K, while an antiferromagnetic transition occurs in other model compounds of the competing system with ferromagnetic 1NN interaction. For that reason, Rb$_2$Cu$_2$Mo$_3$O$_{12}$ is an ideal model compound to study properties of the incommensurate ground state that are unconfirmed experimentally.

description: We present two dimensional hydrodynamic calculations of free expanding supergalactic winds, taking into consideration strong radiative cooling. Our main premise is that supergalactic winds are powered by collections of superstar clusters. Every individual superstar cluster is a source of a high metallicity radiative supersonic outflow (paper I, 2003, ApJ, 590, 791). The interaction of winds from neighboring knots of star formation is shown to lead to a collection of stationary oblique shocks and crossing shocks, able to structure the general outflow into a network of dense and cold, kpc long filaments that originate near the base of the outflow. The shocks also lead to extended regions of diffuse soft X-ray emission and furthermore, to channel the outflow with a high degree of collimation into the intergalactic medium.

 REFERRED SPECIMEN. — SAM PQ 2826, a fragment of cranium including most of the vertex, the right and part of the left premaxillary sac fossae.
LOCALITY. — Trawled at 35°11’S, 23°26’E, south coast of South Africa, Indian Ocean, depth of 1000 m.
DESCRIPTION AND DISCUSSION
(FIG. 12; TABLE 3)
The anterior surface of the ascending process of the premaxilla is distinctly concave up to its dorsal portion, overhanging the premaxillary sac fossa. The highly asymmetric premaxillary crests (the right crest two times wider than the left) are anterolaterally directed. The nasals are greatly elongated anteriorly, being almost twice longer than wide. Their median suture is anteriorly shifted to the left.
 SAM PQ 2826 only differs from the Recent Ziphius cavirostris in: its larger size (see comparison of measurements with the largest skull of Z. cavirostris from the SAM collection, Table 3), the longer contact between nasal and premaxillary crest (a condition intermediary between Z. cavirostris and the Pliocene Tusciziphius crispus), and the relatively smaller nasals.
 Considering the strong similarities with Z. cavirostris at the level of the vertex, this specimen should be referred to the same genus. Because of its clearly larger size it may represent a new species of Ziphius, but in view of its fragmentary preservation diagnosis at specific level is not currently possible.

description: The aim of this article is to determine the forms and the extent of cooperation between poviat (cities) and commune offices and the institutions supporting the development of tourism and entrepreneurship in Lubelskie Voivodeship. The research within eleven poviat offices was conducted with the use of individual, standardized straight interview. The postal questionnaire was used to test sixty-five commune offices. Finally, results were obtained from twenty-six units. The cooperation between poviat offices and the institutions supporting the development of tourism and entrepreneurship takes financial and non-financial forms. The most important are: joint promotional actions in the media, providing the technical infrastructure, establishing contacts with foreign counterparts of aid organizations. Fairly popular form of help from the poviat offices is sharing their financial resources to the institutions that are the subject of analysis. Commune offices are particularly active in the process of continuous exchange of information, developing common strategies and action programs, and making joint development activities. Unfortunately, the communes are not active in establishing contacts abroad, which could allow to use the proven, effective action patterns of twinning institutions from abroad. Less than one third of poviat offices faces barriers in cooperation with the organizations supporting the development of tourism and entrepreneurship. They result from the current legal requirements. Restrictions are also often associated with the lack of funds. From the perspective of commune offices the most important were financial barriers, lack of activity on the part of the business environment in collaboration with commune offices and low interestof residents in the development of tourism and entrepreneurship. Research indicates that the important prerequisite for effective cooperation between the communal and poviat territorial self-government units and organizations contributing to the development of tourism and business in Lubelskie Voivodeship is to obtain the necessary financial resources, which may partly come from EU funds and grants and subsidies for development of tourism and entrepreneurship. The chance for more effective cooperation, it would be to involve in joint projects of local government employees and employees of “business environment”, who often are not able to work together effectively.

description: The federal government can directly address the massive market failures at the center of our healthcare enterprise by establishing a new Health Advanced Research Projects Agency (HARPA) modeled after the Defense Advanced Research Projects Agency (DARPA)—the agency the Department of Defense uses to build new capabilities for national defense. The need for HARPA is twofold. First, developing treatments for disease is difficult and time-consuming. HARPA will provide the sustained drive needed to push through challenges and achieve medical breakthroughs by building new platform technologies. Second, the U.S. healthcare system largely relies on the private sector to leverage national investments in basic research and develop commercially available treatments and cures. This model means that diseases for which investments are risky or downstream profit potential is low are often ignored. HARPA will step in where private companies do not, addressing market failures with direct investments that ensure that all patients have hope for a brighter future. HARPA will leverage existing basic science research programs supported by taxpayer dollars, as well as the efforts of the private sector, to develop new capabilities for disease prevention, detection, and treatment and overcome the bottlenecks that have historically limited progress. To do this, we have to think and act differently about how we address human health challenges. HARPA would support research that directly affirms, refutes, or otherwise changes current clinical practice. It would do this using milestone-driven, time-limited contracts as the central mechanism for driving innovation. This will ensure efficiency, transparency, and optimize success.

description: Land-use regression (LUR) models are important for the assessment of air pollution concentrations in areas without measurement stations. While many such models exist, they often use manually constructed features based on restricted, locally available data. Thus, they are typically hard to reproduce and challenging to adapt to areas beyond those they have been developed for. In this paper, we advocate a paradigm shift for LUR models: We propose the Data-driven, Open, Global (DOG) paradigm that entails models based on purely data-driven approaches using only openly and globally available data. Progress within this paradigm will alleviate the need for experts to adapt models to the local characteristics of the available data sources and thus facilitate the generalizability of air pollution models to new areas on a global scale. In order to illustrate the feasibility of the DOG paradigm for LUR, we introduce a deep learning model called MapLUR. It is based on a convolutional neural network architecture and is trained exclusively on globally and openly available map data without requiring manual feature engineering. We compare our model to state-of-the-art baselines like linear regression, random forests and multi-layer perceptrons using a large data set of modeled $\text{NO}_2$ concentrations in Central London. Our results show that MapLUR significantly outperforms these approaches even though they are provided with manually tailored features. Furthermore, we illustrate that the automatic feature extraction inherent to models based on the DOG paradigm can learn features that are readily interpretable and closely resemble those commonly used in traditional LUR approaches.

description: The VLA Galactic Plane Survey (VGPS) of the first Galactic quadrant was searched for HI emission with velocities well above the maximum velocity allowed by Galactic rotation. A sample of 17 small fast-moving clouds was identified. The distribution of the ensemble of clouds in longitude and velocity indicates that the clouds are part of the Galactic disk, despite their large forbidden velocity. The median angular diameter of the clouds detected in the VGPS is 3.4 arcminutes. These clouds would not be noticed in previous low resolution surveys because of strong beam dilution. Assuming each cloud is located at the tangent point, a median cloud has a diameter of 10 pc, HI mass of 60 M_sun, and a velocity more than 25 km/s beyond the local terminal velocity derived from 12CO observations. Three clouds in the sample have a velocity between 50 and 60 km/s in excess of the local terminal velocity. The longitude distribution of the sample peaks near l = 30 degrees, while the latitude distribution of the clouds is nearly flat. The observed longitude and latitude distributions are compared with simulated distributions taking into account the selection criteria of the cloud search. It is found that the number of clouds declines with distance from the Galactic center, with an exponential scale length 2.8 - 8 kpc at the 99% confidence level. We find a lower limit to the scale height of the clouds of 180 pc (HWHM), but the true value is likely significantly higher.

title: Neural Stem Cell Compartments in a Mouse Model of Globoid Cell Leukodystrophy: Implication for Therapeutic Strategies
Creators: name: Santambrogio, Sara
Publisher: name: The Open University
Year: 2011

description: Globoid cell leukodystrophy (GLD) is a rare genetic lysosomal disorder due to deficiency in the B-galactocerebrosidase (GALC) enzyme. GLD affects mainly children; the prognosis is severe, leading to death few years after the diagnosis. Demyelination is believed to occur as a consequence of Psychosine accumulation and neuroinflammation. Clinical observations in GLD babies suggest that GALC deficiency might affect myelination before overt storage and inflammation, but this issue has been poorly addressed in pre-clinical studies. Similarly, little is known regarding the effect of GALC deficiency on neural stem cell (NSC) in the neurogenic niches during CNS development. The goal of this study was to extensively characterize the role of GALC in regulating the function of NSC niches during the disease progression in Twitcher (Twi) mice, a relevant GLD model. By morphological and functional analysis we showed altered cellular organization and loss of proliferating neuroblasts in the subventricular zone (SVZ) niche of Twi mice as a function of disease progression. These data were confirmed by in vitro experiments showing decreased numbers of primary neurospheres generated from Twi NSC/progenitors. Both defects were rescued to normal levels in symptomatic Twi mice chronically treated with anti-inflammatory drugs. These results, as well as the up-regulation of several inflammatory molecules observed in Twi brains starting from the early symptomatic stage, suggested a major contribution by neuroinflammation at the late stages of the disease. However, these data did not rule out a direct contribution of GALC deficiency nor do they exclude a role of GALC in maintaining a functional niche during CNS development. Indeed, our results indicate decreased proliferation and maturation of NSC/progenitors derived from asymptomatic Twi mice, suggesting that GALC deficiency might lead to neurogenic impairment independently from CNS inflammation. These results improve our understanding of the pathogenic mechanisms of GLD with important implications for therapy.

description: The goal of the analysis is to examine the changes in the structure of insurance products and channels of their distribution in Poland in the years 2002-2008 in the context of the changes taking place in insurance sectors in other EU countries. The research is based on the data on insurance companies obtained from the Polish Financial Authorities, the Polish Chamber of Insurance and the European Federation of Insurers and Reinsurers CEA. The results indicate that insurance companies changed their product structure, inter alia by offering more life insurance as an investment vehicle for household savings, as well as by reducing the share of motor insurance and increasing that of financial and property insurance. Insurers transformed the distribution structure: they significantly increased sales through the banking network and reduced sales through their own facilities and insurance agents and brokers. This trend brings the distribution structure of the Polish insurance sector closer to the structure of insurance sectors in Austria, Belgium, France and Italy, i.e. countries with bank-oriented financial systems.

description: Various resonant and near-resonant patterns form in a light-sensitive Belousov-Zhabotinsky (BZ) reaction in response to a spatially-homogeneous time-periodic perturbation with light. The regions (tongues) in the forcing frequency and forcing amplitude parameter plane where resonant patterns form are identified through analysis of the temporal response of the patterns. Resonant and near-resonant responses are distinguished. The unforced BZ reaction shows both spatially-uniform oscillations and rotating spiral waves, while the forced system shows patterns such as standing-wave labyrinths and rotating spiral waves. The patterns depend on the amplitude and frequency of the perturbation, and also on whether the system responds to the forcing near the uniform oscillation frequency or the spiral wave frequency. Numerical simulations of a forced FitzHugh-Nagumo reaction-diffusion model show both resonant and near-resonant patterns similar to the BZ chemical system.

 OTHER GENERA INCLUDED. — Indopacetus Moore, 1968, Mesoplodon Gervais, 1850, Ihlengesi n. gen., Africanacetus n. gen., and Khoikhoicetus n. gen.
EMENDED DIAGNOSIS. — Hyperoodontinae differ from all the other Ziphiidae in the deep anteromedian excavation of the nasals.
DISCUSSION
 Hyperoodontinae as defined here follows the content of the subfamily suggested by Muizon (1991); they correspond neither to the tribe Hyperoodontini sensu Moore 1968, including Hyperoodon, Indopacetus, Mesoplodon, and Tasmacetus nor to the subtribe Hyperoodontina sensu Moore 1968, only including Hyperoodon and Mesoplodon.

description: Les élèves d’origine sociale modeste aspirent à des filières académiques moins sélectives que leurs pairs de même niveau scolaire mais d’origine sociale favorisée. Plusieurs raisons sont mises à jour : premièrement, les élèves d’origine modeste sous-estiment leurs capacités scolaires actuelles par rapport aux élèves d’origine favorisée ; ensuite, ils anticipent une forte différence dans leurs chances de succès dans le futur ; en outre, ils ont tendance à se conformer à leurs pairs. Par ailleurs, l’action des parents et des enseignants dans le processus d’orientation tend à accroître ces inégalités d’aspirations pour les élèves faibles, tandis qu’elle réduit ces inégalités pour les élèves au-dessus de la médiane. Ces résultats permettent de proposer des pistes d’interventions permettant de réduire les inégalités sociales d’aspirations scolaires.
description:  Pupils from modest socio-economic backgrounds choose less selective academic tracks than others at the same level of ability. Pupils from more modest backgrounds underestimate their own ability; they believe that they are less likely to succeed in a selective academic track, and they have a tendency to conform to the choices of their peers. In addition, outside influence (from the parents or school) over the course of the last year of junior high tends to exacerbate the gap for weaker students, but narrow the gap for stronger students. We propose specific policy interventions based on these findings.

description: The closed neighborhood conflict-free chromatic number of a graph $G$, denoted by $χ_{CN}(G)$, is the minimum number of colors required to color the vertices of $G$ such that for every vertex, there is a color that appears exactly once in its closed neighborhood. Pach and Tardos [Combin. Probab. Comput. 2009] showed that $χ_{CN}(G) = O(\log^{2+\varepsilon} Δ)$, for any $\varepsilon > 0$, where $Δ$ is the maximum degree. In [Combin. Probab. Comput. 2014], Glebov, Szabó and Tardos showed existence of graphs $G$ with $χ_{CN}(G) = Ω(\log^2Δ)$. In this paper, we bridge the gap between the two bounds by showing that $χ_{CN}(G) = O(\log^2 Δ)$.
