description: Irregular conformal block is motivated by the Argyres-Douglas type of N=2 super conformal gauge theory. We investigate the classical/NS limit of the irregular conformal block using spectral curve on a Riemann surface with irregular punctures, which is equivalent to the loop equation of irregular matrix model. The spectral curve is reduced to the second order (Virasoro symmetry, $SU(2)$ for the gauge theory) and third order ($W_3$ symmetry, $SU(3)$) differential equations of a polynomial with finite degree. The Virasoro and W symmetry generate flow equations in the spectral curve and determine the irregular conformal block, hence the partition function of the Argyres-Douglas theory ala AGT conjecture.

description: To inform the design of a multilevel in-store intervention, this qualitative study utilized in-depth semistructured interviews with 28 managers and 10 employees of small-to-medium-sized Latino food stores (tiendas) in San Diego, California, to identify factors within the tienda that may influence Latino customers’ grocery-shopping experiences and behaviors. Qualitative data analysis, guided by grounded theory, was performed using open coding. Results suggest that future interventions should focus on the physical (i.e., built structures) and social (i.e., economic and socio-cultural) dimensions of store environments, including areas where the two dimensions interact, to promote the purchase of healthy food among customers.

description: The analysis of household wealth dynamic remains an important methodology in the identification of poverty traps. To overcome measurement issues in survey data, livelihoods-based approaches of the dynamics of poverty are typically examined using panel regressions of a livelihoods regression on household assets and other socio-economic factors over time. In this paper, we characterise the livelihoods regression as a ‘livelihoods technology’, and use a latent class-technology approach to account for heterogeneity in how households generate a livelihood. We use a detailed dataset from rural India covering 213 households across 2001–2014, and control for selection issues through a Heckman Selection model. Our results are the first in the wealth dynamics literature to show that substantial heterogeneity exists in the technologies with which households generate their livelihoods. Importantly, we show that accounting for heterogeneity in household livelihoods ‘technologies’ more readily identifies different equilibria in wealth levels and provides previously foregone information on who is poor and why they remain poor.

 Triana (1871) used the collection Spruce 2014 to describe H. angustifolia, although there is no mention to the herbarium where the material was deposited. Duplicates of this collection exist at BM, BR, C, E, F, G, GH, K, LD, M, MG, NY, and P. The specimen K000537024 was selected as lectotype, because it was the most representative taking into account the original description, showing well-conserved vegetative and reproductive structures and bearing Triana’s own signature confirming the species identification.

description: High strength and high toughness are usually mutually exclusive in engineering materials. Improving the toughness of strong but brittle materials like ceramics thus relies on the introduction of a metallic or polymeric ductile phase to dissipate energy, which conversely decreases the strength, stiffness, and the ability to operate at high temperature. In many natural materials, toughness is achieved through a combination of multiple mechanisms operating at different length scales but such structures have been extremely difficult to replicate. Building upon such biological structures, we demonstrate a simple approach that yields bulk ceramics characterized by a unique combination of high strength (470 MPa), high toughness (22 MPa.m1/2), and high stiffness (290 GPa) without the assistance of a ductile phase. Because only mineral constituents were used, this material retains its mechanical properties at high temperature (600°C). The bioinspired, material-independent design presented here is a specific but relevant example of a strong, tough, and stiff material, in great need for structural, transportations, and energy-related applications.

description: This paper examines the extent to which characteristics that are beyond the control of children affect their educational outcomes. This is a matter of particular interest because the distribution of educational opportunities will shape future outcomes in other realms. While time-invariant circumstances have already been examined in the inequality of opportunity (IOp) literature, the role of time-varying circumstances has not yet been addressed. For the first time, this paper provides both lower and upper-bound estimates of IOp on learning achievement and assesses the impact of time-varying circumstances on upper-bound measures. It exploits a very rich and unusual longitudinal data set, the Young Lives Study, focusing on a cohort of children that has been followed for fifteen years, surveyed for the first time when they were around a year old. The results suggest that educational IOp is sizable and time-varying circumstances do not have a major impact on upper-bound measures using panel data.
Degenerate higher derivative theories beyond Horndeski: evading the Ostrogradski instability

description: Theories with higher order time derivatives generically suffer from ghost-like instabilities, known as Ostrogradski instabilities. This fate can be avoided by considering "degenerate" Lagrangians, whose kinetic matrix cannot be inverted, thus leading to constraints between canonical variables and a reduced number of physical degrees of freedom. In this work, we derive in a systematic way the degeneracy conditions for scalar-tensor theories that depend quadratically on second order derivatives of a scalar field. We thus obtain a classification of all degenerate theories within this class of scalar-tensor theories. The quartic Horndeski Lagrangian and its extension beyond Horndeski belong to these degenerate cases. We also identify new families of scalar-tensor theories with the intriguing property that they are degenerate despite the nondegeneracy of the purely scalar part of their Lagrangian.

Derivative discontinuity with localized Hartree-Fock potential

description: The localized Hartree-Fock potential has proven to be a computationally efficient alternative to the optimized effective potential, preserving the numerical accuracy of the latter and respecting the exact properties of being self-interaction free and having the correct $-1/r$ asymptotics. In this paper we extend the localized Hartree-Fock potential to fractional particle numbers and observe that it yields derivative discontinuities in the energy as required by the exact theory. The discontinuities are numerically close to those of the computationally more demanding Hartree-Fock method. Our potential enjoys a "direct-energy" property, whereby the energy of the system is given by the sum of the single-particle eigenvalues multiplied by the corresponding occupation numbers. The discontinuities $c_\uparrow$ and $c_\downarrow$ of the spin-components of the potential at integer particle numbers $N_\uparrow$ and $N_\downarrow$ satisfy the condition $c_\uparrow N_\uparrow+c_\downarrow N_\downarrow=0$. Thus, joining the family of effective potentials which support a derivative discontinuity, but being considerably easier to implement, the localized Hartree-Fock potential becomes a powerful tool in the broad area of applications in which the fundamental gap is an issue.

description: Despite common conceptions, evidence on whether No Child Left Behind (NCLB) has had adverse effects for low achieving students is mixed. We hypothesize that the incentive to shift attention away from the lowest achieving students increases with the rigor of state standards. Using panel data from students in North Carolina, we exploit two natural experiments: increases in the rigor of standards in math in 2006 and then again in reading in 2008. We report an increase in test score gaps between low and high achievers and students near grade level. Adverse effects on low achievers are largest in the lowest achieving schools. We discuss the policy implications of our findings given the widespread adoption of more rigorous Common Core Standards.

description: The motherhood penalty for developed countries is well-established in the economic literature. Childbirth intensifies the traditional gender roles that affect paid and unpaid work and contributes to the persistence of the gender labour gap. However, little is known about this phenomenon for developing contexts. This paper investigates the motherhood effects on women’s formal employment and wage trajectories in Uruguay. We document significant and robust motherhood penalties in the labour market, applying an event study method to almost 20 years of social security administrative data. One year after childbirth, formal monthly labour earnings decrease by 22 per cent. This drop fails to recover over time, and ten years after the arrival of children, women’s earnings are 40 per cent below their level just before childbirth. This penalty is mainly driven by a drop in formal employment and, to a lesser extent, a wage decline for those remaining employed. Heterogeneous analysis shows that low-wage women face higher motherhood penalties than high-wage women. Interestingly, these negative effects on wages and formal employment have reduced over time, and recent mothers face lower motherhood penalties.
Head Start at Ages 3 and 4 Versus Head Start Followed by State Pre-K: Which Is More Effective?

description: As policy-makers contemplate expanding preschool opportunities for low-income children, one possibility is to fund two, rather than one year of Head Start for children at ages 3 and 4. Another option is to offer one year of Head Start followed by one year of pre-k. We ask which of these options is more effective. We use data from the Oklahoma pre-k study to examine these two ‘pathways’ into kindergarten using regression discontinuity to estimate the effects of each age-4 program, and propensity score weighting to address selection. We find that children attending Head Start at age 3 develop stronger pre-reading skills in a high quality pre-kindergarten at age 4 compared with attending Head Start at age 4. Pre-k and Head Start were not differentially linked to improvements in children’s pre-writing skills or pre-math skills. This suggests that some impacts of early learning programs may be related to the sequencing of learning experiences to more academic programming.

Calibrating transition metal energy levels and oxygen bands in first principles calculations: accurate prediction of redox potentials and charge transfer in lithium transition metal oxides

description: Transition metal (TM) oxides play an increasingly important role in technology today including applications such as catalysis, solar energy harvesting, and energy storage. In many of these applications, the details of their electronic structure near the Fermi level are critically important for their properties. We propose a first-principles based computational methodology for the accurate prediction of oxygen charge transfer in TM oxides and lithium TM (Li-TM) oxides. To obtain accurate electronic structures, the Heyd-Scuseria-Ernzerhof (HSE06) hybrid functional is adopted and the amount of exact Hartree-Fock exchange (mixing parameter) is adjusted to reproduce reference band gaps. We show that the HSE06 functional with optimal mixing parameter yields not only improved electronic densities of states but also better energetics (Li-intercalation voltages) for LiCoO2 and LiNiO2 as compared to GGA, GGA+U and standard HSE06. We find that the optimal mixing parameters for TM oxides are system-specific and correlate with the covalency (ionicity) of the TM species. Strong covalent (ionic) nature of TM-O bonding leads to lower (higher) optimal mixing parameters. We find that optimized HSE06 functionals predict stronger hybridization of the Co 3d and O 2p orbitals than GGA, resulting in a greater contribution from oxygen states to charge compensation upon delithiation in LiCoO2. We also find that the band gaps of Li-TM oxides increase linearly with the mixing parameter, enabling the straightforward determination of optimal mixing parameters based on GGA (α = 0.0) and HSE06 (α = 0.25) calculations. Our results also show that G0W0@GGA+U band gaps of TM oxides (MO, M = Mn, Co, Ni) and LiCoO2 agree well with experimental references, suggesting that G0W0 calculations can be used as a reference for the calibration of the mixing parameter in case no experimental band gap has been reported.

Relative submajorization and its use in quantum resource theories

description: We introduce and study a generalization of majorization called relative submajorization and show that it has many applications to the resource theories of thermodynamics, bipartite entanglement, and quantum coherence. In particular, we show that relative submajorization characterizes both the probability and approximation error that can be obtained when transforming one resource to another, also when assisted by additional standard resources such as useful work or maximally-entangled states. These characterizations have a geometric formulation as the ratios or differences, respectively, between the Lorenz curves associated with the input and output resources. We also find several interesting bounds on the reversibility of a given transformation in terms of the properties of the forward transformation. The main technical tool used to establish these results is linear programming duality.

 On describing H. granulata, Triana (1871) cited three syntypes, Spruce 1386, 2075 and 3360. The gathering Spruce 3360 is labelled with more complete information on the collection locality, as well as being better preserved, enabling comparisons with the protologue. Within the duplicates of this collection, we selected the specimen K000006405 as lectotype, because it is well preserved, and with substantial reproductive material attached to the branches.
 It should be emphasized that this same Spruce numeration (3360) was also used by him to record two other different specimens (BR 0000005187935, P01818593), which were analyzed by Cogniaux (1888) to describe Henriettea spruceana, which is clearly distinct from H. granulata.

description: The work concerns the development of a new business idea, created in the framework of W4T exploitation strategy, called KAYT- Know As You Throw. KAYT is system aimed to encourage the continuous improvement in urban waste management. It's based on the idea that the habits of waste producers towards separate collection can be improved by simply informing them in a continuous, convenient way, combining both technology (apps etc.) and one- to-one meeting with real informers, adding some economic benefits for those who “want to be informed”. KAYT is highlighted in recent Best Environmental Management practices on Waste document by the European Commission (June 2018). But the effective impact on waste urban plans is missing.
Changes in the menu of manipulation: Electoral fraud, ballot stuffing, and voter pressure in the 2011 Russian election
Creators: name: Harvey, Cole J.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Vote-buying and voter intimidation are costly, complicated, and risky ways to manage elections. Why, then, do hybrid regimes utilize such tactics rather than ballot stuffing or election falsification? Such methods to mobilize voters require the construction of patronage networks that can be used to mobilize or demobilize clients beyond the election, and to display the incumbent's organizational strength. These networks are most valuable in places where opposition groups are active; consequently direct voter pressure should be more common in competitive areas. This paper uses data from Russia's 83 regions during the 2011 election to compare patterns of extra-legal mobilization with patterns of ballot stuffing and falsification. I conclude that local political competitiveness structures the mix of electoral manipulation tactics employed.

description: We demonstrate a facile method to produce crystallographically textured, macroporous materials using a combination of modified ice templating and templated grain growth (TGG). The process is demonstrated on alumina and the lead-free piezoelectric material sodium potassium niobate. The method provides macroporous materials with aligned, lamellar ceramic walls which are made up of crystallographically aligned grains. Each method showed that the ceramic walls present a long-range order over the entire sample dimensions and have crystallographic texture as a result of the TGG process. We also present a modification of the March-Dollase equation to better characterize the overall texture of materials with textured but slightly misaligned walls. The controlled crystallographic and morphologic orientation at two different length scales demonstrated here can be the basis of multifunctional materials.

description: In this paper we demonstrate how, using the coset construction, a theory can be systematically made Weyl invariant by gauging the scale symmetry. We show that an analog of the inverse Higgs constraint allows the elimination of the Weyl vector (gauge) field in favor of curvatures. We extend the procedure -- previously coined Ricci gauging -- and discuss its subtlety for the case of theories with higher derivatives of conformally variant fields.

description: The graphene material prepared by the chemical reduction method usually has oxygenic functional groups in it and such functional groups often result in interactions between the graphene electrode and the electrolyte in supercapacitors. We have examined the existential form of interactions between graphene as the electrode and three kinds of ionic liquid, 1-ethyl-3-methylimidazolium bis (trifluoromethylsulfonyl) imide (EMI-TFSI), 1-ethyl-3-methylimidazolium tetrafluoroborate (EMI-BF), and 1-methyl-1-propylpiperidinium bis (trifluoromethyl sulfonyl) imide (MPPp-TFSI), as the electrolyte of a supercapacitor. Mass spectroscopy (MS) and Fourier transform infrared spectroscopy (FT-IR) analyses confirmed that the residual hydroxyl groups in graphene were transferred to EMI and TFSI lost oxygen atoms to graphene, while little reaction took place in BF or MPPp, during the process of charging. The chemical reactions are suggested to contribute to the device capacitance while it is also one of the reasons for the decreased electrochemical stability window. In this study the highest energy density achieved using the graphene electrode is 169 Wh kg in MPPp-TFSI electrolyte charged to 4.4 V.

description: The controlled transfer of particles from one site of a spatial lattice to another is essential for many tasks in quantum information processing and quantum communication. Arrays of semiconductor quantum dots and ultracold atoms held in optical lattices, provide two means of studying coherent quantum transport in well-controlled systems. In this work we study how to induce long-range transfer between the two ends of a dimer chain, by coupling states that are localized just on the chain's end-points. This has the appealing feature that the transfer occurs only between the end-points -- the particle does not pass through the intermediate sites -- making the transfer less susceptible to decoherence. We first show how a repulsively bound-pair of fermions, known as a doublon, can be transferred from one end of the chain to the other via topological edge states. We then show how non-topological surface states of the familiar Shockley or Tamm type can be used to produce a similar form of transfer under the action of a periodic driving potential. Finally we show that combining these effects can produce transfer by means of more exotic topological effects, in which the driving field can be used to switch the topological character of the edge states, as measured by the Zak phase. Our results demonstrate how to induce long range transfer of strongly correlated particles by tuning both topology and driving.

Henriettea horridula

description: 5. Henriettea horridula Pilger (1905: 82).
 Type:— “ Brazilen. Manaos”, February 1901, E.H.G. Ule 5398 (lectotype: HBG522811! designated here; isolectotypes: B† [photograph F17263!], CORD00003593!, K000537023!, MG005349!).
 Pilger (1905) described H. horridula based on Ule 5398, but he did not mention the herbarium where it was deposited. The herbaria B and HBG are the most representative regarding Ule’s collection (Borges et al. 2018). However, only a photograph of this specimen is extant in B herbarium, as the original was probably destroyed during the Second World War. Specimens from this collection are deposited in CORD, HBG, K, and MG, and present labels including the collection locality, plant height, flower colour, collector number and date, along with the species name and the indication “n. sp.”. The specimen HBG522811 was chosen here as the lectotype, following Borges et al. (2018) guidelines for lectotypification of Ule’s collections. This specimen is well preserved and morphologicaly representative, with abundant reproductive material, facilitating the comparison with the protologue description.

description: The present project provided causal evidence for self-regulation of social-media content and identified a potential underlying neural mechanism. We tested the premise that successful self-regulation requires limiting the mental representation of temptations in working memory. We showed that loading working memory with neutral contents via attentional distraction, relative to passively watching tempting social-media stimuli, resulted in reduced self-reported desire to use social media, reduced initial attention allocation toward social-media stimuli (reduced late-positive-potential amplitudes), and reduced online representation of social- media stimuli in working memory (reduced contralateral-delay-activity amplitudes).

Designing penalty functions in high dimensional problems: The role of tuning parameters
Creators: name: Sun, Wei
name: Fine, Jason P.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Various forms of penalty functions have been developed for regularized estimation and variable selection. Screening approaches are often used to reduce the number of covariate before penalized estimation. However, in certain problems, the number of covariates remains large after screening. For example, in genome-wide association (GWA) studies, the purpose is to identify Single Nucleotide Polymorphisms (SNPs) that are associated with certain traits, and typically there are millions of SNPs and thousands of samples. Because of the strong correlation of nearby SNPs, screening can only reduce the number of SNPs from millions to tens of thousands and the variable selection problem remains very challenging. Several penalty functions have been proposed for such high dimensional data. However, it is unclear which class of penalty functions is the appropriate choice for a particular application. In this paper, we conduct a theoretical analysis to relate the ranges of tuning parameters of various penalty functions with the dimensionality of the problem and the minimum effect size. We exemplify our theoretical results in several penalty functions. The results suggest that a class of penalty functions that bridges L0 and L1 penalties requires less restrictive conditions on dimensionality and minimum effect sizes in order to attain the two fundamental goals of penalized estimation: to penalize all the noise to be zero and to obtain unbiased estimation of the true signals. The penalties such as SICA and Log belong to this class, but they have not been used often in applications. The simulation and real data analysis using GWAS data suggest the promising applicability of such class of penalties.

description: We theoretically investigate a Bose-condensed exciton gas out of equilibrium. Within the framework of the combined BCS-Leggett strong-coupling theory with the non-equilibrium Keldysh formalism, we show how the Bose-Einstein condensation (BEC) of excitons is suppressed to eventually disappear, when the system is in the non-equilibrium steady state. The supply of electrons and holes from the bath is shown to induce quasi-particle excitations, leading to the partial occupation of the upper branch of Bogoliubov single-particle excitation spectrum. We also discuss how this quasi-particle induction is related to the suppression of exciton BEC, as well as the stability of the steady state.
