description: We present the detection of the highly forbidden $2^{3\!}S_1 \rightarrow 3^{3\!}S_1$ atomic transition in helium, the weakest transition observed in any neutral atom. Our measurements of the transition frequency, upper state lifetime, and transition strength agree well with published theoretical values, and can lead to tests of both QED contributions and different QED frameworks. To measure such a weak transition, we developed two methods using ultracold metastable ($2^{3\!}S_1$) helium atoms: low background direct detection of excited then decayed atoms for sensitive measurement of the transition frequency and lifetime; and a pulsed atom laser heating measurement for determining the transition strength. These methods could possibly be applied to other atoms, providing new tools in the search for ultra-weak transitions and precision metrology.

description: The propensity to self-administer cocaine may be a function of both its positively reinforcing and aversive effects, with the latter acting as a limiting factor on overall drug-taking. And although the anatomical and neurochemical substrates for cocaine's positively reinforcing effects have been well characterized, relatively little is known about the physiological underpinnings of its aversive effects. Cocaine is a non-selective inhibitor of the three monoamine neurotransmitters dopamine, norepinephrine and serotonin, the first of which appears to be the predominant system mediating cocaine's positively reinforcing effects. To better characterize the relative roles of these systems in the induction of cocaine's aversive effects, the current assessments examined cocaine and other monoaminergic compounds in the conditioned taste aversion (CTA) preparation. Specifically, in Experiment 1, cocaine was compared to three reuptake inhibitors, each possessing relative specificity for one of the three monoamine transporters, in their ability to induce CTAs. Rats were given access to a novel saccharin solution and injected with either cocaine, GBR 12909, desipramine or clomipramine at one of three doses (18, 32 and 50 mg/kg). Desipramine generally induced stronger aversions than GBR 12909 and clomipramine and was the only compound that matched cocaine's aversion acquisition function at all doses (although all compounds conditioned some degree of aversion), suggesting that the noradrenergic system may be the largest monoaminergic contributor to cocaine's aversive effects. To further clarify a role for the this system, cocaine-induced CTAs (10, 18 and 32 mg/kg) were conducted under conditions of antagonism at the norepinephrine alpha1 and beta receptors using prazosin (0.3 mg/kg; Experiment 3) and propranolol (10 mg/kg; Experiment 4), respectively, at doses that were determined to be non-aversive in the CTA preparation (Experiment 2). In each case of noradrenergic antagonism, there was no diminishment in the aversions conditioned with cocaine, suggesting that these effects are mediated by non-noradrenergic NT activity. Furthermore, prazosin and propranolol administration appeared to facilitate the conditioned aversive effects of cocaine. The implications of these findings in regards to other monoaminergic processes are discussed.

description: We explicitly demonstrate that, contrary to recent claims, the dynamics of a generalized Chaplygin gas model with an equation of state $p=-C$ (where $C$ is a positive constant) is equivalent to that of a standard $Λ$CDM model to first order in the metric perturbations. We further argue that the analogy between the two models goes well beyond linear theory and conclude that they cannot be distinguished based on gravity alone.

description: We study impacts of dimension-five lepton-number violating operators associated with two same-sign weak bosons, $\ell^\pm \ell^{\prime \pm} W^\mp W^\mp$, on current and future experiments for neutrino oscillation, lepton-number violating rare processes and high-energy collider experiments. These operators can contain important information on the origin of tiny neutrino masses, which is independent of that from the so-called Weinberg operator. We examine constraints on the coefficients of the operators by the neutrino oscillation data. Upper bounds on the coefficients are also investigated by using the data for processes of lepton number violation such as neutrinoless double beta decays and $μ^-$-$e^+$ conversion. These operators can also be directly tested by searching for lepton-number violating dilepton production via the same-sign W boson fusion process at high-energy hadron colliders like the Large Hadron Collider. We find that these operators can be considerably probed by these current and future experiments.

description: We present a detailed chemical analysis of 22 stars along the colour-magnitude sequence of the intermediate-age (1.7 Gyr) open cluster IC 4651. We find for the cluster a well-defined Fe abundance of [Fe/H]= 0.10 +/- 0.03 (internal errors), with a reddening E(b-y)=0.091. We also derive abundances for the alpha elements Mg, Si, Ti, and Ca and find a moderate enhancement of the three former elements. Among the Fe group elements, Cr and Ni are slightly overabundant ([X/Fe] ~ 0.05). The Na abundance among the giants is more than 0.2 dex higher than in the dwarfs. We interpret this as due to dredge-up of 23Na in the giants. Li abundances show a well-defined pattern: the Solar-type stars have an almost constant Li abundance, just below that of the Hyades, and the Li-dip is pronounced and well determined. Turnoff stars just above the dip have a `cosmic' Li abundance, but within a very small range of magnitudes (0.25 mag) higher on the turnoff, Li drops by more than a factor 10 implying that some extra mixing is required. Among the giants, two probable clump stars show detectable Li, while all the other (likely) RGB stars do not. We show that rotating stellar models including the most recent developments for meridional circulation and turbulence by shear instabilities explain very well the observed Li pattern. The possibility remains open that the giants exhibiting the highest Li abundances are actual RGB bump stars which have just been through the so-called "lithium flash".

An examination of the relationships among mindfulness, emotional acceptance, emotional awareness, self -compassion, forgiveness, and self -judgment

description: Although the positive effects of mindfulness interventions are promising, the changes in psychological processes leading to these positive outcomes are not yet understood. This study examined the relationship between one potential mediator, emotional acceptance, and mindfulness. The study also investigated three processes that may serve to facilitate the development of emotional acceptance: self-compassion, forgiveness, and self judgment. One hundred and forty-two participants belonging to a mindfulness meditation community completed a packet of questionnaires measuring the constructs of interest. The results from this study suggest that mindfulness, operationalized as the amount of mindfulness meditation practice experience, is associated with emotional acceptance, self-compassion, and low levels of self-judgment. Mindfulness was not found to be associated with forgiveness and emotional awareness. When compared to participants with lower levels of mindfulness experience, those who had practiced mindfulness for five or more years exhibited the highest levels of self-compassion and emotional acceptance, and the lowest levels of self-judgment. Individuals with lower levels of experience did not significantly differ from each other on these three variables. Self-compassion, forgiveness, and self judgment were not found to moderate the relationship between emotional awareness and emotional acceptance. Levels of self-compassion, self-judgment, and forgiveness were found to partially mediate the relationship between mindfulness experience and emotional acceptance. Future studies should address causal relationships between these variables (emotional acceptance, self-compassion, self judgment, forgiveness, and emotional awareness) and mindfulness and examine whether these variables partially mediate the relationship between mindfulness practice and positive clinical outcomes.

description: As a future upgrade of the Frascati phi factory DAPHNE an increase of the center-of-mass energy of the accelerator up to W=2GeV has been proposed (DAFNE2). In this case the hadronic cross section in the energy range between 1-2 GeV can be measured with the KLOE detector. The feasibility of these measurements and the impact on the hadronic contribution to the anomalous magnetic moment of the muon are discussed. The possibilities for an energy scan are compared with the radiative return technique, in which the accelerator is running at a fixed center-of-mass energy and ISR-events are taken to lower the invariant mass of the hadronic system.

Agricultural production, human capital, and rural nonfarm activities: Evidence from Nigeria
Creators: name: Oseni, Gbemisola
Publisher: name: American University
Year: 2023

description: The four chapters in this dissertation explore the factors that affect the livelihoods of rural households in Nigeria with an emphasis on understanding the role of the nonfarm economy. Although most rural households are involved in the farm sector, the nonfarm sector has grown significantly in recent decades, and its role in rural development has become increasingly important. The first chapter of this dissertation examines the effect of participation in nonfarm activities on crop expenses of farm households. The relationship is modeled using a non-separable agricultural household model. The model suggests that participating in nonfarm activities can relax the credit constraints facing farm households and reduce risk thereby helping households improve farm production and smooth consumption over time. The results show that participation in nonfarm activities has a positive and significant effect on crop expenses. The second chapter investigates the impact of nonfarm activities on school enrollment of children ages 6 to 18. Becker and Tomes (1986) model of parental investment in children is used to model the relationship. A discrete time hazard model is used to empirically examine the effect of household nonfarm income and household participation in nonfarm activities on the hazard of their children dropping out of school. The results show that children from households that earn income from nonfarm activities are not only more likely to ever enroll in school, but also complete more years of schooling than those from households that do not earn nonfarm income. The third chapter examines the effect of education on household activity choices and earnings. A household earnings model and the common Mincer (1974) human capital earnings model were used in the analyses. The results show that schooling influences household activity choices (allocative effect) as well as earnings from the activities (worker effect). More educated households are more likely to participate in nonfarm activities and less likely to participate in farm activities. Schooling also has a bigger effect on nonfarm earnings than farm earnings, given participation. Finally, the fourth chapter summarizes the findings of this dissertation noting the relevance of results for both the economics literature and rural development policy.

description: We present K, L and M diffraction-limited images of NGC 1068 obtained with NAOS+CONICA at VLT/YEPUN over a 3.5" field around the central engine. Hot dust (Tcol = 550-650 K) is found in three different regions : (a) in the true nucleus, seen as a slightly NS elongated, core of extremely hot dust, "resolved" in K and L with respective diameters of ~5 pc and 8.5 pc ; (b) along the NS direction, as a "spiral arm" and a southern tongue ; (c) as a set of parallel elongated nodules ("wave-like") bracketting the jet. Several structures observed on radio maps, mid-IR or HST UV-visible maps are seen, so that a precise registration can be done from UV to 6 cm. These results do support the current interpretion that source (a) corresponds to emission from dust near sublimation temperature delimiting the walls of the cavity in the central obscuring torus. Structure (b) is thought to be a mixture of hot dust and active star forming regions along a micro spiral structure that could trace the tidal mechanism bringing matter to the central engine. Structure c)which was not known, exhibits too high a temperature for "classical'' grains ; it is most probably the signature of transiently heated very small dust grains (VSG) : "nano-diamonds", which are resistant and can form in strong UV field or in shocks, are very attractive candidates. The "waves'' can be condensations triggered by jet induced shocks, as predicted by recent models. First estimates, based on a simple VSG model and on a detailed radiative transfer model, do agree with those interpretations, both qualitatively and quantitatively.

description: The Symmetric Tensor Approximation problem (STA) consists of approximating a symmetric tensor or a homogeneous polynomial by a linear combination of symmetric rank-1 tensors or powers of linear forms of low symmetric rank. We present two new Riemannian Newton-type methods for low rank approximation of symmetric tensor with complex coefficients.The first method uses the parametrization of the set of tensors of rank at most $r$ by weights and unit vectors.Exploiting the properties of the apolar product on homogeneous polynomials combined with efficient tools from complex optimization, we provide an explicit and tractable formulation of the Riemannian gradient and Hessian, leading to Newton iterations with local quadratic convergence. We prove that under some regularity conditions on non-defective tensors in the neighborhood of the initial point, the Newton iteration (completed with a trust-region scheme) is converging to a local minimum.The second method is a Riemannian Gauss--Newton method on the Cartesian product of Veronese manifolds. An explicit orthonormal basis of the tangent space of this Riemannian manifold is described. We deduce the Riemannian gradient and the Gauss--Newton approximation of the Riemannian Hessian. We present a new retraction operator on the Veronese manifold.We analyze the numerical behavior of these methods, with an initial point provided by Simultaneous Matrix Diagonalisation (SMD).Numerical experiments show the good numerical behavior of the two methods in different cases and in comparison with existing state-of-the-art methods.

description: We investigate the spatial distribution, the space velocities and age distribution of the pre-main sequence (PMS) stars belonging to Ophiuchus, Lupus and Chamaeleon star-forming regions (SFRs), and of the young early-type star members of the Scorpius-Centaurus OB association. These young stellar associations extend over the galactic longitude range from 280 deg. to 360 deg., and are at a distance interval of around 100 and 200 pc. This study is based on a compilation of distances, proper motions and radial velocities from the literature for the kinematic properties, and of basic stellar data for the construction of Hertzsprung-Russel diagrams. Although there was no well-known OB association in Chamaeleon, the distances and the proper motions of a group of 21 B- and A-type stars, taken from the Hipparcos Catalogue, lead us to propose that they form a young association. We show that the young early-type stars of the OB associations and the PMS stars of the SFRs follow a similar spatial distribution, i.e., there is no separation between the low and the high-mass young stars. We find no difference in the kinematics nor in the ages of these two populations studied. We analyze the different scenarios for the triggering of large-scale star-formation that have been proposed up to now, and argue that most probably we are observing a spiral arm that passes close to the Sun. The alignment of young stars and molecular clouds and the average velocity of the stars in the opposite direction to the Galactic rotation agree with the expected behavior of star formation in nearby spiral arms.

description: Shock jump conditions are obtained for steady-state, plane shocks with oblique magnetic fields and arbitrary flow speeds. For ultrarelativistic and nonrelativistic shocks, the jump conditions may be solved analytically. For mildly relativistic shocks, analytic solutions are obtained for isotropic pressure using an approximation for the adiabatic index that is valid in high sonic Mach number cases. In the more general case of gyrotropic pressure, the jump conditions cannot be solved analytically without additional assumptions, and the effects of gyrotropic pressure are investigated by parameterizing the distribution of pressure parallel and perpendicular to the magnetic field. Our numerical solutions reveal that relatively small departures from isotropy (e.g., about 20%) produce significant changes in the shock compression ratio, r, at all shock Lorentz factors, including ultrarelativistic ones, where an analytic solution with gyrotropic pressure is obtained. In particular, either dynamically important fields or significant pressure anisotropies can incur marked departures from the canonical gas dynamic value of r=3 for a shocked ultrarelativistic flow and this may impact models of particle acceleration in gamma-ray bursts and other environments where relativistic shocks are inferred. The jump conditions presented apply directly to test-particle acceleration, and will facilitate future self-consistent numerical modeling of particle acceleration at oblique, relativistic shocks.

description: Patient nonadherence to medication regimens is a widespread phenomenon that compromises the efficacy of pharmacological treatment and results in considerable human and financial costs. This problem is particularly challenging in the treatment of schizophrenia, where symptoms of the disorder itself, as well as the need for long-term treatment, pose threats to adherence. Due to the prevalence of nonadherence, experts have recommended a proactive approach that includes attention to adherence even if a problem has not yet developed. Although there is a substantial body of research regarding risk factors for nonadherence, methods of assessing nonadherence, and interventions for nonadherence, very little is known about psychiatric management of adherence in routine clinical practice. The current report presents a profile of "good adherence management" that involves proactive focus on common roots of nonadherent behavior. Based on available practice guidelines, the clinical research literature, and recommendations of adherence experts, the model includes attention to 3 typologies of nonadherence identified by Koocher, McGrath, and Gudas (1990): patients' inadequate knowledge of the medication regimen, psychosocial resistance, and adaptive nonadherence. This model provided the basis for a national survey of adherence management among psychiatrists treating adult outpatients with schizophrenia. Data from 53 psychiatrists are presented. Findings suggested that psychiatrists were providing comprehensive adherence management for some of their patients, some of the time, but approximately half did not follow World Health Organization recommendations to include attention to patient adherence at every visit with all patients. Unstructured patient interviews were the most commonly utilized tool to assess adherence. Psychiatrist self-efficacy and self-reported familiarity with the adherence research literature were consistently associated with more intensive adherence management behaviors. Contrary to expectations, specific training in adherence issues was not associated with more intensive adherence management. Conceptualizing medication adherence as an ongoing treatment goal, as well as focusing greater attention on common causes of nonadherence during routine medical visits, may have the potential to improve outcomes for adult outpatients with schizophrenia while substantially reducing healthcare costs.

Structure Formation, Melting, and the Optical Properties of Gold/DNA Nanocomposites: Effects of Relaxation Time

description: We present a model for structure formation, melting, and optical properties of gold/DNA nanocomposites. These composites consist of a collection of gold nanoparticles (of radius 50 nm or less) which are bound together by links made up of DNA strands. In our structural model, the nanocomposite forms from a series of Monte Carlo steps, each involving reaction-limited cluster-cluster aggregation (RLCA) followed by dehybridization of the DNA links. These links form with a probability $p_{eff}$ which depends on temperature and particle radius $a$. The final structure depends on the number of monomers (i. e. gold nanoparticles) $N_m$, $T$, and the relaxation time. At low temperature, the model results in an RLCA cluster. But after a long enough relaxation time, the nanocomposite reduces to a compact, non-fractal cluster. We calculate the optical properties of the resulting aggregates using the Discrete Dipole Approximation. Despite the restructuring, the melting transition (as seen in the extinction coefficient at wavelength 520 nm) remains sharp, and the melting temperature $T_M$ increases with increasing $a$ as found in our previous percolation model. However, restructuring increases the corresponding link fraction at melting to a value well above the percolation threshold. Our calculated extinction cross section agrees qualitatively with experiments on gold/DNA composites. It also shows a characteristic ``rebound effect,'' resulting from incomplete relaxation, which has also been seen in some experiments. We discuss briefly how our results relate to a possible sol-gel transition in these aggregates.

Model Selection in Factor-Augmented Regressions with Estimated Factors

description: This paper proposes two consistent model selection procedures for factor-augmented regressions in finite samples. We first demonstrate that the usual cross-validation is inconsistent, but that a generalization, leave-d-out cross-validation, selects the smallest basis for the space spanned by the true factors. The second proposed criterion is a generalization of the bootstrap approximation of the squared error of prediction of Shao (1996) to factor-augmented regressions. We show that this procedure is consistent. Simulation evidence documents improvements in the probability of selecting the smallest set of estimated factors than the usually available methods. An illustrative empirical application that analyzes the relationship between expected stock returns and factors extracted from a large panel of United States macroeconomic and financial data is conducted. Our new procedures select factors that correlate heavily with interest rate spreads and with the Fama-French factors. These factors have strong predictive power for excess returns.

description: Although globalization has shaped the world economy in recent decades, emerging economies have experienced impressive growth compared to developed economies, suggesting a decoupling between developed and emerging business cycles. Using observed developed and emerging economy activity variables, we investigate whether the latter assertion can be supported by observed data. Based on a two-level factor model, we assume these activity variables can be decomposed into a global component, emerging or developed common component and idiosyncratic national shocks. We propose a statistical test for the null hypothesis of a one-level specification, where it is irrelevant to distinguish between emerging and developed latent factors against the two-level alternative. This paper provides a theoretical justification and simulations that document the testing procedure. An application of the test to a panel of developed and emerging countries leads to strong statistical evidence of decoupling.
