Morphological components of yield in sweet potato (Ipomoea batatas (L.) Lam.)
Creators: name: Soenarto
Publisher: name: University of British Columbia
Year: 2009

description: Growth and productivity were analyzed in two cultivars of sweet potato (Ipomoea batatas (L.) Lam.): a bushy type (cv BO 44T3) and a spreading type (cv BO 129T9). Two main aims were to determine how tuberous root yield and aboveground morphological measures respond to population density in different growing seasons, and to identify morphological measures of aboveground plant parts that are indicators of high tuberous root yield. In addition, the study was used to compare several techniques of plant growth analysis. Two field experiments were performed using randomized complete block designs. One was repeated in 1995 and 1996 and involved a single final harvest after the cultivars were grown at three levels of plant population density. The second was carried out in 1996; it involved a sequence of harvests performed at different times during crop growth at a single population density. Five different techniques were used to analyze the experimental results: conventional plant growth analysis, inverse yield-density regression analysis, allometric analysis, path analysis and yield component analysis. These procedures offered complementary interpretations in that each provided new perspectives on plant performance. The two cultivars arrived at similar final tuberous root yields through different chronologies of growth. Increasing population density reduced tuberous root yield along with most other measures of growth. Responsiveness to population density, i. e., intraspecific competition, differed among the different plant measures and years, and the two cultivars did not always respond to density to the same degree. Where significant differences were found between years, the responsiveness was always higher in the year that was less favourable to growth (1996). Some effects of population density on tuberous root yield were direct, but indirect effects on yield via responses of aboveground measures were stronger. Throughout growth, the addition and expansion of leaves were positively correlated with tuberous root growth. At the final harvest, variation in number of stems per plant was an important indicator of variation in tuberous root yield.

description: We have investigated the electrical resistivity of the heavy fermion superconductor PrOs$_{4}$Sb$_{12}$ in the mixed state. We found unusual double minima in the flux-flow resistivity as a function of magnetic field below the upper critical field for the first time, indicating double peaks in the pinning force density ($F_{\rm P}$). Estimated $F_{\rm P}$ at the peak exhibits apparent dependence on applied field direction; composed of two-fold and four-fold symmetries mimicking the reported angular dependence of thermal conductivity ($κ$). The result is discussed in correlation with the double step superconducting (SC) transition in the specific heat and the multiple SC-phases inferred from the angular dependence of $κ$.

From Abstract Concept to Active Participants: Reflections on a Purposive Sample

description: This article draws upon my experience of conceptualizing, identifying and recruiting interviewees for a doctoral study of Bangladeshi citizens working for social change in their own country. Understanding how these key workers negotiate the complex dilemmas and conflicting demands involved in working for social change adds to our understanding how civil society actors both contribute to, and are constituents of, sustainable human development. Methodologically, the study can be described as a psychoanalytically-informed sociological enquiry, drawing on feminist and decolonial perspectives, that used open-ended life-history and event-centred interviews to elicit multiple ‘small’ personal stories of experience (Phoenix, 2013). From these ‘small’ stories a number of identifiable ‘bigger’ stories, or contextualized narratives (Goodson, 2017), emerged which were analyzed both sociologically, using Bourdieusian social theory, and psychoanalytically in the tradition of British object relations.

description: We investigate a low-dimensional slow-fast model to understand the dynamical origin of El Niño-Southern Oscillation. A close inspection of the system dynamics using several bifurcation plots reveals that a sudden large expansion of the attractor occurs at a critical system parameter via a type of interior crisis. This interior crisis evolves through merging of a cascade of period-doubling and period-adding bifurcations that leads to the origin of occasional amplitude-modulated extremely large events. More categorically, a situation similar to homoclinic chaos arises near the critical point, however, atypical global instability evolves as a channel-like structure in phase space of the system that modulates variability of amplitude and return time of the occasional large events and makes a difference from the homoclinic chaos. The slow-fast timescale of the low-dimensional model plays an important role on the onset of occasional extremely large events. Such extreme events are characterized by their heights when they exceed a threshold level measured by a mean-excess function. The probability density of events' height displays multimodal distribution with an upper-bounded tail. We identify the dependence structure of interevent intervals to understand the predictability of return time of such extreme events using autoregressive integrated moving average model and box plot analysis.

description: [Abridged] The S-stars motion around the Galactic center (Sgr A*) implies the existence of a compact source with a mass of about $4\times 10^6 M_\odot$, traditionally assumed to be a massive black hole (BH). Important for any model is the explanation of the multiyear, accurate astrometric data of S2 and the challenging G2: its post-pericenter velocity decelerates faster than expected from a Keplerian orbit around the putative BH. This has been reconciled in the literature by acting on G2 a drag force by an accretion flow. Alternatively, we show that the S2 and G2 motion is explained by the "core-halo" fermionic dark matter (DM) profile of the fully-relativistic Ruffini-Argüelles-Rueda (RAR) model. It has been already shown that for 48-345 keV fermions, it accurately fits the rotation curves of the Milky-Way halo. We here show that, for a fermion mass of 56 keV, it explains the time-dependent data of the position (orbit) and light-of-sight radial velocity (redshift function $z$) of S2 and G2, the latter without a drag force. We find the RAR model fits better the data: the mean of reduced chi-squares of the orbit and $z$ data are, for S2, $\langle\barχ^2\rangle_{\rm S2, RAR}\approx 3.1$ and $\langle\barχ^2\rangle_{\rm S2, BH}\approx 3.3$ while, for G2, $\langle\barχ^2\rangle_{\rm G2, RAR}\approx 20$ and $\langle\barχ^2\rangle_{\rm G2, BH}\approx 41$. For S2 the fits of the $z$ data are comparable, $\barχ^2_{z,\rm RAR}\approx 1.28$ and $\barχ^2_{z,\rm BH}\approx 1.04$, for G2 only the RAR model fits, $\barχ^2_{z,\rm RAR}\approx 1.0$ and $\barχ^2_{z,\rm BH}\approx 26$. In addition, the critical mass for the gravitational collapse of a degenerate 56 keV-fermion DM core into a BH is $\sim 10^8 M_\odot$, which may be the initial seed for the formation of the observed central supermassive BH in active galaxies, such as M87.

Magnetic defects promote ferromagnetism in Zn1-xCoxO

Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: Experimental studies of Zn1-xCoxO as thin films or nanocrystals have found ferromagnetism and Curie temperatures above room temperature and that p- or n-type doping of Zn1-xCoxO can change its magnetic state. Bulk Zn1-xCoxO with a low defect density and x in the range used in experimental thin film studies exhibits ferromagnetism only at very low temperatures. Therefore defects in thin film samples or nanocrystals may play an important role in promoting magnetic interactions between Co ions in Zn1-xCoxO. The electronic structures of Co substituted for Zn in ZnO, Zn and O vacancies, substituted N and interstitial Zn in ZnO were calculated using the B3LYP hybrid density functional in a supercell. The B3LYP functional predicts a band gap of 3.34 eV for bulk ZnO, close to the experimental value of 3.47 eV. Occupied minority spin Co 3d levels are at the top of the valence band and unoccupied levels lie above the conduction band minimum. Majority spin Co 3d levels hybridize strongly with bulk ZnO states. The neutral O vacancy and interstitial Zn are deep and shallow donors, respectively. The Zn vacancy is a deep acceptor and the acceptor level for substituted N is at mid gap. The possibility that p- or n-type dopants promote exchange coupling of Co ions was investigated by computing total energies of magnetic states of ZnO supercells containing two Co ions and an oxygen vacancy, substituted N or interstitial Zn in various charge states. The neutral N defect and the singly-positively charged O vacancy are the only defects which strongly promote ferromagnetic exchange coupling of Co ions at intermediate range.

description: The paper suggests to treat the infrared reflectivity spectra of single crystal perovskite relaxors as fine-grained ferroelectric ceramics: locally frozen polarization makes the dielectric function strongly anisotropic in the phonon frequency range and the random orientation of the polarization at nano-scopic scale requires to take into account the inhomogeneous depolarization field. Employing a simple effective medium approximation (Bruggeman symmetrical formula) to dielectric function describing the polar optic modes as damped harmonic oscillators turns out to be sufficient for reproducing all principal features of room temperature reflectivity of PMN. One of the reflectivity bands is identified as a geometrical resonance entirely related to the nanoscale polarization inhomogeneity. The approach provides a general guide for systematic determination of the polar mode frequencies split by the inhomogeneous polarization at nanometer scale.

Policy ‘Meandering’: The Influence of Mental Health and Well-being in Educational Policies

description: This article contextualizes, and contests, the use of the terms mental health (MH) and well-being in ideologically driven educational policies and practices, market oriented, individualistic and measurable. Alongside an unprecedented worldwide trend to establish an educational ‘turn’, so called ‘therapeutic education’, it is argued that educational policies in the UK have arbitrarily merged, or ‘yoked’, the terms MH and well-being with ethical implication for policy implementation. Through ethnographic and participative methodologies, involving the main social actors to mobilize expert knowledge in two educational settings, the ‘yoking’ of MH with well-being becomes apparent and catalyst for further yoking. Hence, more policies and new concepts emerge as manipulations of school/colleges’ initiatives, such as achieving good results or promoting ‘character’ to engineer next generation citizenry. Juxtaposing the terms MH and well-being to education calls for clearer re-definitions of the aims of education. Every effort should be made by policy makers to keep the two terms independent from each other and well-articulated with performance indicators such as resilience that do not undermine the value of vulnerability. New definitions of MH and well-being should guide policy making and implementation in schools/colleges, to avoid lumping up together heterogeneous and multilayered terms that deserve distinct attention and application.

description: We have analyzed the magnetic field dependences of intensities of all the optical transitions between magnetic sublevels of hyperfine levels, excited with $σ^+$, $π$ and $σ^-$ polarized light, for the $D_1$ and $D_2$ lines of $^{87}$Rb and $^{85}$Rb atoms. Depending on the type of transition and the quantum numbers of involved levels, the Hamiltonian matrices are of $1\times 1$, $2\times 2$, $3\times 3$ or $4\times 4$ dimension. As an example, analytical expressions are presented for the case of $2\times 2$ dimension matrices for $D_1$ line of both isotopes. Eigenvalues and eigenkets are given, and the expression for the transition intensity as a function of $B$ has been determined. It is found that some $π$ transitions of $^{87}$Rb and $^{85}$Rb get completely canceled for certain, extremely precise, values of $B$. No cancellation occurs for $σ^+$ or $σ^-$ transitions of $D_1$ line. For matrices with size over $2\times 2$, analytical formulas are heavy, and we have performed numerical calculations. All the $B$ values cancelling $σ^+$, $π$ and $σ^-$ transitions of $D_1$ and $D_2$ lines of $^{87}$Rb and $^{85}$Rb are calculated, with an accuracy limited by the precision of the involved physical quantities. We believe our modeling can serve as a tool for determination of standardized values of magnetic field. The experimental implementation feasibility and its possible outcome are addressed. We believe the experimental realization will allow to increase precision of the physical quantities involved, in particular the upper state atomic levels energy.

description: Within the t-t'-J model, the charge asymmetry in superconductivity of hole- and electron-doped cuprates is studied based on the kinetic energy driven superconducting mechanism. It is shown that superconductivity appears over a narrow range of doping in electron-doped cuprates, and the superconducting transition temperature displays the same kind of the doping controlled behavior that is observed in the hole-doped case. However, the maximum achievable superconducting transition temperature in the optimal doping in electron-doped cuprates is much lower than that of the hole-doped case due to the electron-hole asymmetry.

Gyr-timescale destruction of high-eccentricity asteroids by spin and why 2006 HY51 has been spared

description: Asteroids and other small celestial bodies have markedly prolate shapes, and the perturbative triaxial torques which are applied during pericenter passages in highly eccentric orbits trigger and sustain a state of chaotic rotation. Because the prograde spin rate around the principal axis of inertia is not bounded from above, it can accidentally reach the threshold value corresponding to rotational break-up. Previous investigations of this process were limited to integrations of $\sim 10^3$ orbits because of the stiff equation of motion. We present here a fast 1D simulation method to compute the evolution of this spin rate over $\sim 10^9$ orbits. We apply the method to the most eccentric solar system asteroid known, 2006 HY51 (with $e = 0.9684$), and find that for any reasonably expected shape parameters, it can never be accelerated to break-up speed. However, primordial solar system asteroids on more eccentric orbits may have already broken up from this type of rotational fission. The method also represents a promising opportunity to investigate the long-term evolution of extremely eccentric triaxial exo-asteroids ($e > 0.99$), which are thought to be common in white dwarf planetary systems

description: Combining crystal structure search and first-principles calculations, we report a series of two-dimensional (2D) metal borides including orthorhombic (ort-) MB6 (M=Mg, Ca) and hexagonal (hex-) MB6 (M=Mg, Ca, Sc, Ti, Sr, Y). Then, we investigate their geometrical structures, bonding properties, electronic structures, mechanical properties, phonon dispersions, thermal stability, dynamic stability, electron-phonon coupling (EPC), superconducting properties and so on. Our ab initio molecular dynamics simulation results show that these MB6 can maintain their original configurations up to 700/1000 K, indicating their excellent thermal stability. All their elastic constants satisfy the Born mechanically stable criteria and no visible imaginary frequencies are observed in their phonon dispersions. The EPC results show that these 2D MB6 are all intrinsic phonon-mediated superconductors with the superconducting transition temperature (Tc??) in the range of 2.2-21.3 K. Among them, the highest Tc (21.3 K) appears in hex-CaB6, whose EPC constant () is 0.94. By applying tensile/compressive strains on ort-/hex-CaB6, we find that the compressive strain can obviously soften the acoustic phonon branch and enhance the EPC as well as Tc. The Tc of the hex-CaB6 can be increased from 21.3 K to 28 K under compressive strain of 3%. These findings enrich the database of 2D superconductors and should stimulate experimental synthesizing and characterizing of 2D superconducting metal borides.

description: This paper reflects some of my PhD research into the ability of subjects to express themselves in a ‘free and frank’ manner to authority figures in an educational context. In doing so I draw particularly on Michel Foucault and his concept of Parrhesia, Leo Tolstoy’s writing connected with social action and education, together with Lauren Berlant’s concept of ‘Impasse’. Writing under these influences I begin with an outline of autonomy, freedom and truth before entering into a description of one aspect of Foucault’s Parrhesia. I then relate this to a sample of my interview respondents’ experiences in an educational context, before continuing with a short discussion of coercion and authority.

description: We present the zero-temperature phase diagram of the one-dimensional t2g-orbital Hubbard model, obtained using the density-matrix renormalization group and Lanczos techniques. Emphasis is given to the case for the electron density n=5 corresponding to five electrons per site, of relevance for some Co-based compounds. However, several other cases for electron densities between n=3 and 6 are also studied. At n=5, our results indicate a first-order transition between a paramagnetic (PM) insulator phase and a fully-polarized ferromagnetic (FM) state by tuning the Hund's coupling. The results also suggest a transition from the n=5 PM insulator phase to a metallic regime by changing the electron density, either via hole or electron doping. The behavior of the spin, charge, and orbital correlation functions in the FM and PM states are also described in the text and discussed. The robustness of these two states varying parameters suggests that they may be of relevance in more realistic higher dimensional systems as well.

Re-Visiting Polymorphous Ideology: Populism of the Left and Right
Creators: name: Varriale, Amedeo
Publisher: name: School of Social Sciences, University of East London
Year: 2021

description: In this article I aim to re-visit the contested concept of populism. I urge scholars to approach the study of this polymorphous ideology known as ‘Populism’ with an open mind. Today, it is no longer necessary to strictly separate the ideological characteristics of populism from its particularistic discursive and strategic elements. I propose that the populism of the left and the right share similarities that could possibly outweigh their differences. I first outline a set of misconceptions that have prevented us from realising that populism does in fact hold a redemptive side to it which can ultimately be positive to contemporary democracy. Second, I discuss the three main modern approaches to populism (ideational, socio-cultural, political-strategic) and provide a brief but useful critique of all of them. Third, I present my very own ‘fresh’ approach to the topic and provide an in-depth definition of populism in order to give “right-wing” and “left-wing” populism a better and fairer hearing, especially in an era where the discontents of world populations towards political elites are increasing. Finally, I share some thoughts on what the future direction of the study of such an intricate marvel like populism should entail, also addressing the question of whether in times likes these the left-right divide is still relevant.

description: Aims. This study focuses on very luminous Mbol1.5 mag and H-Ks>0.4 mag in the LMC, SMC, M31, and M33 from 2MASS data. Methods.The data were taken from the 2MASS All-Sky Point Source catalogue archive. We used Virtual Observatory tools and took advantage of its capabilities at various stages in the analysis. Results. It is well known that stars with the colors we selected correspond mainly to carbon stars. Although the most luminous AGBs detected here contain a large number of carbon stars,they are not included in existing catalogues produced from data in the optical domain, where they are not visible since they are dust-enshrouded. A comparison of the AGB stars detected with combined near and mid-infrared data from MSX and 2MASS in the LMC shows that 10% of the bright AGB stars are bright carbon stars never detected before and that the other 50% are OH/IR oxygen rich stars, whereas the 40% that remain were not cross-matched. Conclusions. The catalogues of the most luminous AGB stars compiled here are an important complement to existing data. In the LMC, these bright AGB stars are centrally located, whereas they are concentrated in an active star-formation ring in M31. In the SMC and M33, there are not enough of them to draw definite conclusions, although they tend to be centrally located. Their luminosity functions are similar for the four galaxies we studied.

description: Graph filters and their inverses have been widely used in denoising, smoothing, sampling, interpolating and learning. Implementation of an inverse filtering procedure on spatially distributed networks (SDNs) is a remarkable challenge, as each agent on an SDN is equipped with a data processing subsystem with limited capacity and a communication subsystem with confined range due to engineering limitations. In this letter, we introduce a preconditioned gradient descent algorithm to implement the inverse filtering procedure associated with a graph filter having small geodesic-width. The proposed algorithm converges exponentially, and it can be implemented at vertex level and applied to time-varying inverse filtering on SDNs.

Limits on weak magnetic confinement of neutral atoms
Creators: name: Sackett, C. A.
Publisher: name: arXiv

Subjects: subject: Other Condensed Matter (cond-mat.other)
subject: FOS: Physical sciences

description: It is shown that when a magnetic field is used to support neutral atoms against the gravitational force mg, the total curvature of the field magnitude B must be larger than m^2 g^2/(2 μ^2 B), where mu is the magnetic moment of the atoms. This limits the minimum confinement strength obtainable for a trapped atomic gas. It is also conjectured that the curvature must be larger than twice this value for a magnetic potential that varies in only one or two dimensions, such as an atomic waveguide.

description: We have observed ten red giant stars in four old Large Magellanic Cloud globular clusters with the high-resolution spectrograph MIKE on the Magellan Landon Clay 6.5-m telescope. The stars in our sample have up to 20 elemental abundance determinations for the alpha-, iron-peak, and neutron-capture element groups. We have also derived abundances for the light odd-Z elements Na and Al. We find NGC 2005 and NGC 2019 to be more metal-rich than previous estimates from the Ca II triplet, and we derive [Fe/H] values closer to those obtained from the slope of the red giant branch. However, we confirm previous determinations for Hodge 11 and NGC 1898 to within 0.2 dex. The LMC cluster [Mg/Fe] and [Si/Fe] ratios are comparable to the values observed in old Galactic globular cluster stars, as are the abundances [Y/Fe], [Ba/Fe], and [Eu/Fe]. The LMC clusters do not share the low-Y behavior observed in some dwarf spheroidal galaxies. [Ca/Fe], [Ti/Fe], and [V/Fe] in the LMC, however, are significantly lower than what is seen in the Galactic globular cluster system. Neither does the behavior of [Cu/Fe] as a function of [Fe/H] in our LMC clusters match the trend seen in the Galaxy, staying instead at a constant value of ~0.8. Because not all [alpha/Fe] ratios are suppressed, these abundance ratios cannot be attributed solely to the injection of Type Ia SNe material, and instead reflect the differences in star formation history of the LMC vs. the Milky Way. We conclude that many of the abundances in the LMC globular clusters we observed are distinct from those observed in the Milky Way, and these differences are intrinsic to the stars in those systems.

Electrically switchable hidden spin polarization in antiferroelectric crystals

Year: 2020
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: Hidden spin polarization (HSP) emerges in centrosymmetric crystals where visible spin splittings in the real space can be observed because of the lack of inversion symmetry in each local sector. Starting from tight-binding models, we introduce nonsymmorphic antiferroelectric (AFE) crystals as a new class of functional materials that can exhibit strong local spin polarization. Such AFE crystals can be basically classified as in-plane and out-of-plane AFE configurations, and can be reversibly switched to the ferroelectric phase by an electric field to manifest global spin splittings, enabling a nonvolatile electrical control of spin-dependent properties. Based on first-principle calculations, we predict the realization of strong HSP in the AFE phase of a newly-discovered two-dimensional materials, quintuple-layer (QL) LiBiO$_2$. Furthermore, the spontaneous electric polarization ($\sim$ 0.3 nC/m) and the transition barrier as well as the tunable spin polarization of QL-LiBiO$_2$ are discussed.

description: We analytically study the one-dimensional Asymmetric Simple Exclusion Process (ASEP) with open boundaries under sublattice-parallel updating scheme. We investigate the stationary state properties of this model conditioned on finding a given particle number in the system. Recent numerical investigations have shown that the model possesses three different phases in this case. Using a matrix product method we calculate both exact canonical partition function and also density profiles of the particles in each phase. Application of the Yang-Lee theory reveals that the model undergoes two second-order phase transitions at critical points. These results confirm the correctness of our previous numerical studies.

Discrete-phase-randomized measurement-device-independent quantum key distribution

Publisher: name: arXiv
Year: 2020
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Measurement-device-independent quantum key distribution removes all detector-side attacks in quantum cryptography, and in the meantime doubles the secure distance. The source side, however, is still vulnerable to various attacks. In particular, the continuous phase randomization assumption on the source side is normally not fulfilled in experimental implementation and may potentially open a loophole. In this work, we first show that indeed there are loopholes for imperfect phase randomization in measurement-device-independent quantum key distribution by providing a concrete attack. Then we propose a discrete-phase-randomized measurement-device-independent quantum key distribution protocol as a solution to close this source-side loophole.

description: A short overview is presented of the role that Low and Intermediate mass stars play in Galactic Chemical Evolution; their action affects key elements and isotopes, like deuterium, He-3, Li-7, carbon and nitrogen, and s-process nuclei. In all those cases, critical uncertainties still remain and are briefly discussed here.

Symmetric multiparty-controlled teleportation of an arbitrary two-particle entanglement

description: We present a way for symmetric multiparty-controlled teleportation of an arbitrary two-particle entangled state based on Bell-basis measurements by using two Greenberger-Horne-Zeilinger states, i.e., a sender transmits an arbitrary two-particle entangled state to a distant receiver, an arbitrary one of the $n+1$ agents via the control of the others in a network. It will be shown that the outcomes in the cases that $n$ is odd or it is even are different in principle as the receiver has to perform a controlled-not operation on his particles for reconstructing the original arbitrary entangled state in addition to some local unitary operations in the former. Also we discuss the applications of this controlled teleporation for quantum secret sharing of classical and quantum information. As all the instances can be used to carry useful information, its efficiency for qubits approaches the maximal value.

Investigating Iraqi EFL University Students' Knowledge of Grammatical Collocations in English

Publisher: name: University of Leicester
Year: 2021
Subjects: Uncategorized

description: This cross-sectional mixed-method study aimed to investigate the effects of grammatical collocations (GCs) frequency, their L1-L2 congruency and transparency, as well as L2 proficiency on Iraqi EFL university students' (IUSs') productive and receptive knowledge of GCs. The study also involved a comparison between IUSs' productive and receptive collocational knowledge as well as an attempt to explore how consciously aware IUSs and their teachers are of GCs and their different types. In addition, the study attempts to explore the way GCs tend to be learned and taught in the study setting. The study involved 112 participants with different L2 proficiency levels. The data collection instruments included a productive knowledge test, a receptive knowledge test (both innovatively designed by the researcher using the BNC and demonstrated good reliability and validity), the grammar part of the Oxford Placement Test (OPT), and semi-structured interviews. The findings of the study revealed that GC frequency, L1-L2 congruency, transparency and L2 proficiency have not only significant main effects on IUSs' collocational knowledge but also significant interaction effects and that L2 proficiency was the best predictor of IUSs' performance. It was also found that IUSs' receptive knowledge of GCs was significantly better than their productive one. Apart from the most common types of time, place and manner GCs, the participants showed that they did not have sufficient L2 explicit knowledge of GCs and their different types or the ability to use accurate terms to refer to them. Most participants' responses indicated that the type of teaching employed to teach GCs tends to be explicit and intentional, especially at the earlier stages. In addition, the vocabulary items comprising GCs often tend to be taught as individual words (i.e. not as part of the GCs). Moreover, explicit teaching tends to be associated with only the most common types of GCs.
Physiologic responses of the fetal lamb to eight day fluoxetine exposure during late gestation

Publisher: name: University of British Columbia
Year: 2009

description: Clinical depression is diagnosed in 10-15% of pregnancies frequently resulting in antidepressant therapy with selective serotonin reuptake inhibitors such as fluoxetine. Human studies have suggested that third trimester exposure to fluoxetine results in negative birth outcomes such as preterm delivery, low birth weight and increased admission to neonatal intensive care units. Based on these findings, we undertook an eight day maternal IV infusion of fluoxetine (FX, 98.5 µg/kg.d) in 14 chronically instrumented pregnant sheep during late gestation (125- 140 d, term = 147 d) with a control group of 15 animals receiving sterile water. In the FX group maternal and fetal plasma FX and norfluoxetine (NFX) concentrations were within the therapeutic range reported in humans. Maternal fluoxetine infusion increased plasma serotonin levels within 15 min of infusion associated with a 20% decrease in uterine artery blood flow. Both plasma serotonin levels and uterine artery blood flow returned to control values by 1 h after infusion. The transient decrease in uterine artery blood flow resulted in fetal hypoxemia during the first 24 h of infusion. Minor alterations in fetal blood gases continued throughout the eight-day infusion period. The incidences of low voltage electrocortical activity (EcoG), eye movements and fetal breathing movements were significantly reduced in the FX group while the incidence of high voltage ECoG was significantly increased during the first 6 h of maternal fluoxetine infusion. These alterations continued throughout the eight days of infusion to a lesser degree. Fetal ACTH and Cortisol plasma concentrations in the FX group increased on Infusion Days 7 and 8 more than in the control group. Late gestation infusion of fluoxetine in sheep did not alter birth weight or gestational age at delivery. In conclusions, late gestation exposure to FX in pregnant sheep transiently altered fetal blood gas status with greater effects on fetal behavioural state and neuroendocrine function. The longer term consequences of these in utero perturbations remains to be determined.
