description: A sum rule for tidal Love number is derived from quantum field theory computations, which relates tidal susceptibility of a spinless body to transition rates of its single graviton emission processes. An analogous sum rule for electromagnetism is given as an example, which is substantiated by comparing to the solved problem of the hydrogen atom. Based on the semiclassical Hawking radiation spectrum, a finite nonvanishing value for quantum corrections to the Love number of Schwarzschild black holes in general relativity is computed using the sum rule, which is known to classically vanish.

description: Today, there are only about 15,000 black farmers in the United States. Declining by 98 percent since 1920, black farmers have suffered losses attributable to public policy, economic pressures, and racial oppression. All of these factors must be addressed if African-American farmers are to survive. In this paper, we use Census of Agriculture data and a follow-on survey in one Mississippi Delta county to review the current situation of black farmers. We introduce the concept of "re-entering farmers" to suggest that a significant number of black farmers, who are not defined as "farmers" by the Census, still own land and want to farm again. The first section of the paper provides a brief overview of the historical and current trends of black farmers in the United States. The second section discusses Delta County, drawing upon our survey and the Census of Agriculture. The third section discusses the implications of civil rights violations by the former Farmers Home Administration of the U.S. Department of Agriculture. Finally, we conclude with a policy recommendation to slow the drastic decline of African-American farmers.

description: We perform a detailed investigation of moderate-to-high quality X-ray spectra of ten of the most luminous active galactic nuclei (AGNs) known at z>4 (up to z~6.28). This study includes five new XMM observations and five archived X-ray observations (four by XMM and one by Chandra). We find that the X-ray power-law photon indices of our sample, composed of eight radio-quiet sources and two that are moderately radio loud, are not significantly different from those of lower redshift AGNs. The upper limits obtained on intrinsic neutral hydrogen column densities, N_H4 radio-quiet AGNs to Gamma=1.97^{+0.06}_{-0.04}, with no detectable intrinsic dispersion from source to source. We also obtain a strong constraint on the mean intrinsic column density, N_H4 are, on average, not more absorbed than their lower-redshift counterparts. All this suggests that the X-ray production mechanism and the central environment in radio-quiet AGNs have not significantly evolved over cosmic time. The mean equivalent width of a putative neutral narrow Fe Ka line is constrained to be 4 radio-quiet AGN.

description: This literature review focuses on recent and contemporary tenancy structures in Asia, Africa, and Latin America. Tenancy for purposes of this review is broadly defined to include different leasing arrangements such sharecropping, labor tenancy, fixed cash rentals, and reverse leasing. We have limited our discussion to private leasing of agricultural land, thereby ignoring issues pertaining to leasing of public, forest, and other noncrop lands. The purpose of this literature review is to provide a basis for evaluation of the desirability, feasibility, and potential content of regulatory guidelines for lease agreements that might permit the land-lease market to operate effectively. The works discussed herein are both theoretical and empirical. We have attempted to locate the most recent literature on tenancy for Asia, Africa, and Latin America. If contemporary literature is scarce or if historical developments are useful to understanding current tenancy trends, references and inclusion of recent past experiences and dynamics are included. As can be expected, the availability of studies on tenancy in the three regions is quite different.

Material examined
ESTONIA • 1 spec.; Pirgu River outcrops; Adila Formation, Pirgu Regional Stage; TUG 1745-299 • 1 spec.; Vormsi Island, Hosholm shore (tower outcrop); Adila Formation, Pirgu Regional Stage; GIT 840-269 • 1 spec.; Vormsi Island, Saxby shore; Kõrgessaare Formation, Vormsi Regional Stage; GIT 878-76.
Description
GIT 840-269 (Fig. 45C) is a fragment of a phragmocone, exogastrically curved with an angle of expansion of 20° at a conch height between 37 mm and 26 mm. At its apical end, the height and width are 26 mm and 23 mm, respectively (CHI = 1.13). The septa are 6 mm apart where the conch height is 31 mm (RCL = 0.19), and the sutures form lateral lobes. The siphuncle is marginally positioned and expands into the chambers. The septal foramen is 2.5 mm wide where the conch height is 26 mm (RSH = 0.1).
GIT 840-76 (Fig. 45D–E) is an exogastrically curved fragment of a phragmocone with a conch height and width of 20 mm and 18 mm, respectively, at its apical end (CHI = 1.11) with sutures which form lateral lobes. The sutures are 5 mm apart where the conch height is 23 mm (RCL = 0.22). The conch curvature, CHI, RCL and curvature of the suture line are similar to that of GIT 840-269.
TUG 1745-299 is a fragment of a phragmocone of an apparently exogastric cyrtocone with a conch width of 24 mm. It is closely similar to the two specimens, but too poorly preserved to be measured.
Remarks
These three specimens are described in order to document the presence of a relatively large, exogastrically curved brevicone, different from the genera and species described herein, but not well enough known to determine the order, genus, or species.

The Effect of Metacognitive Training for Writing on Attention to Detail of First Graders
Creators: name: Seibert, Kirsten
Publisher: name: Maryland Shared Open Access Repository
Year: 2014
Subjects: subject: Education -- Research papers (Graduate)

description: The purpose of this study was to examine the effectiveness of a metacognitive training method involving a writing checklist that was designed to help first graders become more attentive to detail in their writing assignments and focus more productively during their class work time. The intervention group (n = 20) and the control group (n = 13) came from a convenience sample. This study had a pretest/posttest design that used as its dependent variable a researcher-designed writing prompt and rubric that produced an Attention to Detail score. The pre-test was used to confirm that the two groups did not differ on Attention to Detail scores prior to the intervention. After the intervention group had explicit instruction and 15 days experience in using the checklist on daily writing assignments, the two groups were given the post- assessment. The mean Attention to Detail scores on the post-intervention writing test of the intervention group (Mean = 10.60, SD = 1.98) did not differ significantly from the mean Attention to Detail scores of the control group (Mean = 9.38, SD = 3.40) [t(31) = -1.30, p > .05). Implications, limitations, and ideas for future research are discussed.

description: The electronic properties and spectroscopic features of a magnetic trimer with a Kondo-like coupling to a non-magnetic metallic substrate are analyzed at zero temperature. The substrate density of states is depressed in the trimer neighbourhood, being exactly zero at the substrate chemical potential. The size of the resonance strongly depends on the magnetic state of the trimer, and exhibits a two-state behavior. The geometrical dependence of these results agree qualitatively with recent experiments and could be reproduced in a triangular quantum dot arrangement.

"A criminal in one place, a gentleman in another" : regulating early Canadian gambling venues
Creators: name: Bliss, James Robert Quartus
Publisher: name: University of British Columbia
Year: 2009

description: This thesis examines the legal history of regulating early gambling venues in Canada. Two case studies illustrate the manner in which a 'spatially oriented' legal regime emerged: early Chinese gambling dens in Victoria and Vancouver, and racetracks in Ontario. The term 'spatially oriented' recognizes that gambling law, both past and present, regulates gambling places rather than the activity of gaming itself. Moreover, the application of the law was spatially inconsistent: early Chinese gambling dens received a discriminate amount of police scrutiny while an express exemption in the criminal law insulated racetrack betting from sanction. The theoretical perspectives of moral regulation and critical legal geography are used to show that discourses of law, liberalism, race and morality are inextricably linked to 'place.' In particular, the relationship between law and place is highlighted to show how moral and ideological geographies may be both reflected in law, and created by law. The implication for early Canadian gambling venues was the development of a reputation of respectability for particular forums, such as the racetrack, versus the association of criminal connotations with unlicensed social gambling clubs, such as the Chinese gambling den.
A Generalized Momentum/Complexity Correspondence

description: Holographic complexity, in the guise of the Complexity = Volume prescription, comes equipped with a natural correspondence between its rate of growth and the average infall momentum of matter in the bulk. This Momentum/Complexity correspondence can be related to an integrated version of the momentum constraint of general relativity. In this paper we propose a generalization, using the full Codazzi equations as a starting point, which successfully accounts for purely gravitational contributions to infall momentum. The proposed formula is explicitly checked in an exact pp-wave solution of the vacuum Einstein equations.

description: This letter investigates parallelism approaches for equation and Jacobian evaluations in large-scale power flow calculation. Two levels of parallelism are proposed and analyzed: inter-model parallelism, which evaluates models in parallel, and intra-model parallelism, which evaluates calculations within each model in parallel. Parallelism techniques such as multi-threading and single instruction multiple data (SIMD) vectorization are discussed, implemented, and benchmarked as six calculation workflows. Case studies on the 70,000-bus synthetic grid show that equation evaluations can be accelerated by ten times, and the overall Newton power flow advances the state of the art by 20%.
NEW MARKETING ISSUES VIA PIK CERTIFICATES

description: The Food Security Act of 1985 permits payment of farm program benefits in part with PIK certificates. PIK certificates can do things that cash alone cannot do. This special capacity gives PIK certificates special value. A market determined premium has existed for them from the beginning. Briefly during the harvest of 1986, premiums were as high as 30 percent. To date, premiums have rarely been much less than 5 percent. In this paper we will attempt to better understand the reasons for the PIK certificate premiums and explore an alternate design of the system that would, for the most part, eliminate them. A second objective of this paper is to understand how the special powers of PIK certificates are capable of changing the market environment itself. The fact that PIK certificates can acquire grain owned by the CCC, in the Farmer Owned Reserve, in the Special Producer Storage Loan Program, or under 9-month loan at approximately current market prices is an important change in the rules. Previously, CCC inventory had been available to the market only at prices well above the loan rate, with minor exceptions pertaining to the condition of the grain. Farmer Owned Reserve inventory was available at prices at or above a trigger-release price. The traditional 9-month loan program and the SPSLP tend to support prices at levels above the loan rate plus interest carrying charges. The availability of these supplies to the market via a new set of rules creates a radical new market environment, something closer to a free market (Kennedy) (Westcott and Hanthorn). Additional topics discussed include the role of PIK certificates toward alleviating storage shortages, toward creating a defacto marketing loan, and toward possible USDA control of regional markets.

description: Bifurcation analysis has many applications in different scientific fields, such as electronics, biology, ecology, and economics. In population biology, deterministic methods of bifurcation are commonly used. In contrast, stochastic bifurcation techniques are infrequently employed. Here we establish stochastic P-bifurcation behavior of (i) a growth model with state-dependent birth rate and constant death rate, and (ii) a logistic growth model with state-dependent carrying capacity, both of which are driven by multiplicative symmetric stable Levy noise. Transcritical bifurcation occurs in the deterministic counterpart of the first model, while saddle-node bifurcation takes place in the logistic growth model. We focus on the impact of the variations of the growth rate, the per capita daily adult mortality rate, the stability index, and the noise intensity on the stationary probability density functions of the associated non-local Fokker-Planck equation. In the first model, the bifurcation parameter is the ratio of the population birth rate to the population death rate. In the second model, the bifurcation parameter corresponds to the sensitivity of carrying capacity to change in the size of the population near equilibrium. In each case, we show that as the value of the bifurcation parameter increases, the shape of the steady-state probability density function changes and that both stochastic models exhibit stochastic P-bifurcation. The unimodal density functions become more peaked around deterministic equilibrium points as the stability index increases. While an increase in any one of the other parameters has an effect on the stationary probability density function. That means the geometry of the density function changes from unimodal to flat, and its peak appears in the middle of the domain, which means a transition occurs.

description: Since the pioneering work of Kelvin on Laplace tidal equations, a zoology of trapped waves have been found in the context of coastal dynamics. Among them, the one originally computed by Kelvin plays a particular role, as it is an unidirectional mode filling a frequency gap between different wave bands. The existence of such Kelvin waves is robust to changes in the boundary shape and in changes of the underlying model for the coast. This suggests a topological interpretation that has yet up to now remained elusive. Here we rectify the situation, by taking advantage of a reformulation of the shallow water dynamics that highlights an analogy with the celebrated Haldane model in condensed matter physics. For any profile of bottom topography, the number of modes that transit from one wave band to another in the dispersion relation is predicted by computing a first Chern number describing the topology of complex eigenmodes in a dual, simpler wave problem.

description: Jing-an oral liquid (JA) is a Chinese herbal formula used in the treatment of Tourette syndrome (TS); however, its mechanism is unclear. To investigate the effects of JA on amino acid neurotransmitters and microglia activation in vivo and in vitro. Sixty male Sprague–Dawley rats were divided into a control group and 5 TS groups. TS was induced in rats with intraperitoneal injection of 1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (1 mg/kg) and in BV2 cells with lipopolysaccharide. Control and model rats were administered saline, whereas treatment groups were administered JA (5.18, 10.36, or 20.72 g/kg) or tiapride (a benzamide, 23.5 mg/kg) by gavage once daily for 21 days. Stereotypic behaviour was tested. The levels of N-methyl-d-aspartate receptor (NMDAR)/mitogen-activated protein kinase/cAMP response element-binding protein (CREB)-related proteins in striatum and BV2 cells were measured via western blots. CD11b and IBa1 levels were also measured. Ultra-high-performance liquid-chromatography was used to determine γ-aminobutyric acid (GABA), glutamic acid (Glu), and aspartic acid (ASP) levels. JA markedly alleviated the stereotype behaviour (25.92 ± 0.35 to 13.78 ± 0.47) in rats. It also increased NMDAR1 (0.48 ± 0.09 to 0.67 ± 0.08; 0.54 ± 0.07 to 1.19 ± 0.18) expression and down-regulated the expression of p-ERK, p-JNK, p-P38, and p-CREB in BV2 cells and rat striatum. Additionally, Glu, ASP, GABA, CD11b, and IBa1 levels were significantly decreased by JA. JA suppressed microglia activation and regulated the levels of amino acid neurotransmitters, indicating that it could be a promising therapeutic agent for TS.

description: The purpose of this study is to determine the impact of homework practices (worksheets/paper & pen) on students’ poor homework habits in standard level Chemistry classes. The measurement tool was the students’ homework completion rates. The study involved a quasi-experimental design in which a control group received traditional homework assignments and the experimental group received the online homework assignments. The study spanned two units from the Baltimore County Public Schools (BCPS) Honors/Standard Chemistry Curriculum and lasted approximately seven weeks. The null hypothesis was supported. The results show that online homework practices did not lead to an increase in homework completion rates. Future research is recommended examining the impact technology-infused homework practices has on homework completion and performance among high school students.

description: We approach the problem of constructing an explicit holographic dictionary for the AdS$_2$/CFT$_1$ correspondence in the context of higher derivative gravitational actions in AdS$_2$ space-times. These actions are obtained by an $S^2$ reduction of four-dimensional ${\cal N}=2$ Wilsonian effective actions with Weyl squared interactions restricted to constant scalar backgrounds. BPS black hole near-horizon space-times fall into this class of backgrounds, and by identifying the boundary operators dual to the bulk fields, we explicitly show how the Wald entropy of the BPS black hole is holographically encoded in the anomalous transformation of the operator dual to a composite bulk field. Additionally, using a 2d/3d lift, we show that the CFT holographically dual to AdS$_2$ is naturally embedded in the chiral half of the CFT$_2$ dual to the AdS$_3$ space-time, and we identify the specific operator in CFT$_1$ that encodes the chiral central charge of the CFT$_2$.
The Effect of Increased Sight Word Knowledge on the Comprehension of Below Level Third Grade Readers

Subjects: subject: Education -- Research papers (Graduate)

description: The purpose of this study was to determine whether increasing sight word knowledge in below
level third grade readers impacts their comprehension of a simple text. The intervention implemented was the repeated use of flash cards with the first through third grade Dolch words, 20 minutes of daily guided reading instruction, interactive games and websites students practiced with during independent time, and homework assignments focused on the sight word practice. The measurement tools used were the 128 Dolch words from first, second, and third grade lists and a passage containing all 220 common Dolch sight words for a pre- and post-test comprehension assessment. This study involved the use of a quasi-experimental, pretest/posttest repeated measures design to compare data from before the intervention was implemented in February 2014 to data from after the intervention was implemented in April 2014. Achievement gains in sight word knowledge were apparent for all students involved in the study. Findings of the study may have been influenced by intervening factors such as changes in classroom schedules, parent involvement at home or questions of validity with the assessment. Research in the area of sight word knowledge should continue given the relationship between the sight word recognition and increased reading comprehension.
The Anisotropy of Galactic Cosmic Rays as a Product of Stochastic Supernova Explosions

description: We study the effect of the stochastic character of supernova explosions on the anisotropy of galactic cosmic rays below the knee. We conclude that if the bulk of cosmic rays are produced in supernova explosions the observed small and nearly energy independent amplitude of the anisotropy and its phase are to the large extent determined by the history of these explosions in the vicinity of the solar system, namely by the location and the age of the supernova remnants, within a few kpc, which give the highest contribution to the total intensity at the present epoch. Among the most important factors which result in the small magnitude and the energy independence of the anisotropy amplitude are the mixed primary mass composition, the effect of the Single Source and the Galactic Halo. Special attention is given to the phase of the anisotropy. It is shown that the excessive flux from the Outer Galaxy can be due to the location of the solar system at the inner edge of the Orion Arm which has the enhanced density and rate of supernova explosions.

description: We systematically construct flatbands (FB) for tight-binding models on simple Bravais lattices in space dimension $d \geq 2$ in the presence of a static uniform DC field. Commensurate DC field directions yield irreducible Wannier-Stark (WS) bands in perpendicular dimension $d - 1$ with $d$-dimensional eigenfunctions. The irreducible bands turn into dispersionless flatbands in the absence of nearest neighbor hoppings between lattice sites in any direction perpendicular to the DC field. The number of commensurate directions which yield flatbands is of measure one. We arrive at a complete halt of transport, with the DC field prohibiting transport along the field direction, and the flatbands prohibiting transport in all perpendicular directions as well. The anisotropic flatband eigenstates are localizing at least factorially (faster than exponential).

description: Coreopsis tinctoria Nutt (Asteraceae), named snow chrysanthemum, is known to have a high level of polyphenols. However, the potential prebiotic effect on modulating intestinal microflora is still unclear. The chemical composition, antioxidant properties of snow chrysanthemum polyphenols (SCPs) and their effects on human intestinal microbiota were investigated. SCPs were extracted using ultrasonic-assisted extraction, and further determined using UPLC-QE Orbitrap/MS. Five assays were used to investigate the antioxidant activities of SCPs. Subsequently, the effects of SCPs on intestinal microbiota in vitro were determined by high throughput sequencing and bioinformatics analysis. Marein, isookanin and cymaroside were the major phenolic compounds, which accounted for 42.17%, 19.53% and 12.25%, respectively. Marein exhibited higher scavenging capacities in DPPH (EC50 = 8.84 µg/mL) and super anion radical assay (EC50 = 282.1 µg/mL) compared to cymaroside and isookanin. The antioxidant capacity of cymaroside was weakest among the three phenolic compounds due to the highest EC50 values, especially for superoxide anion radical assay, EC50 > 800 µg/mL. The result of in vitro fermentation showed that the three phenolic compounds increased the relative abundances of Escherichia/Shigella, Enterococcus, Klebsiella, etc., and isookanin notably increased the relative abundance of Bifidobacterium and Lactobacillus. SCPs exhibited antioxidant properties and potential prebiotic effects on modulating the gut microbiota composition. The findings indicated that SCPs consumption could exert prebiotic activity that is beneficial for human health.

description: We calculate light curves produced by $r$-modes with small azimuthal wavenumbers, $m$, propagating in the surface fluid ocean of rotating neutron stars. We include relativistic effects due to rapid rotation, and propagate photons from the stellar surface to a distant observer using the Schwarzschild metric. The wave motions of the surface $r$-modes are confined to the equatorial region of the star, and the surface pattern of the temperature variation can be either symmetric (for even modes) or anti-symmetric (for odd modes) with respect to the equator. Since for the surface $r$-modes the oscillation frequency in the corotating frame of the star is much smaller than the rotation frequency, $Ω$, we employ the approximation in which the oscillation frequency in the inertial frame, $σ$, is given by $σ= -mΩ$. We find that the $even$, $m = 1$ $r$-mode produces the largest light variations. The dominant Fourier component in the light curves of these modes is the fundamental having $σ=-Ω$, and the first harmonic component having $σ=-2Ω$ is always negligible in comparison. The dominant Fourier component of the even, $m=2$ $r$-modes is the first harmonic. Although the $odd$ $r$-modes produce smaller amplitude light variations compared with the $even$ modes, the light curves of the former have a stronger first harmonic component. If both $m=1$ and 2 $r$-modes are excited simultaneously, a rich variety of light curves is possible, including those having an appreciable first harmonic component. We show that the phase difference, $δ-δ_E$, between the bolometric light curve and that at a particular photon energy can possibly be used as a probe of the stellar compactness, $R/M$, where $R$ and $M$ are the radius and mass of the star.

description: Stroke is an illness with high morbidity, disability and mortality that presents a major clinical challenge. Sanhua decoction (SHD) has been widely used to treat ischaemic stroke in the clinic. However, the potential mechanism of SHD remains unknown. To elucidate the multitarget mechanism of SHD in ischaemic stroke through network pharmacology and bioinformatics analyses. Network pharmacology and experimental validation approach was used to investigate the bioactive ingredients, critical targets and potential mechanisms of SHD against ischaemic stroke. Four herbal names of SHD, ‘ischemic stroke’ or ‘stroke’ was used as a keyword to search the relevant databases. SH-SY5Y cells were treated with various concentrations of SHD (12.5, 25, 50 or 100 μg/mL) for 4 h, exposed to oxygen and glucose deprivation (OGD) for 1 h, then reoxygenation for 24 h. The cell viability was detected by MTT, the lactate dehydrogenase (LDH) was evaluated by ELISA, and protein expression was detected by western blots. SHD treatment increased the survival rate from 65.9 ± 4.3 to 85.56 ± 5.7%. The median effective dose (ED50) was 47.1 μg/mL, the LDH decreased from 288.0 ± 12.0 to 122.8 ± 9.1 U/L and the cell apoptosis rate decreased from 33.6 ± 1.8 to 16.3 ± 1.2%. Western blot analysis revealed that SHD increased the levels of p-PI3k, p-Akt and p-CREB1, and decreased the expression of TNF-α and IL-6. This study suggests that SHD protects against cerebral ischaemic injury via regulation of the PI3K/Akt/CREB1 and TNF pathways.

Cumulative effects of collision integral, strong magnetic field, and quasiparticle description on charge and heat transport in thermal QCD medium

description: Our first aim is to explore the effect of the collision integral with the insurance of instantaneous conservation of particle number on charge and heat transport in a thermal QCD medium. The second aim is to see how the dimensional reduction due to strong magnetic field (B) modulates the transport through the entangled effects, {\em such as} collision-time and occupation probability etc. in collision integral. The final aim is to check how the quasiparticle description through dispersion relation of thermal QCD in strong B, alters the aforesaid conclusions. We observe that modified collision term expedites both transport, which is manifested by large magnitudes of electrical ($σ_{\rm el}$) and thermal ($κ$) conductivities, in comparison to relaxation-collision term. As a corollary, Lorenz number is dominated by the later and Knudsen number is by the former. However, strong B not only flips the dominance of collision term in heat transport, it also causes drastic enhancement of both $σ_{\rm el}$ and $κ$ and reduction in specific heat. As a result, the equilibration factor, Knudsen number becomes much larger than one, which defies physical interpretation. Finally, quasiparticle description in the absence of strong B impedes the transport of charge and heat, resulting in the meagre decrease of conductivities, however, strong B does noticeable observations: conductivities now gets reduced to physically plausible values, T-dependence of $σ_{\rm el}$ gets reversed, {\em i.e.} it now decreases with T, effect of collision integral gets smeared in $κ$ etc. Knudsen number thus becomes much smaller than one, implying that the system be remained in equilibrium. These findings attribute to the fact that the collective modes in the dispersion relation of thermal QCD in strong B sets in much larger scale, manifested by large in-medium masses.

description: We calculate the one-body temperature Green's (Matsubara) function of the unitary Fermi gas via Quantum Monte Carlo, and extract the spectral weight function $A(p,ω)$ using the methods of maximum entropy and singular value decomposition. From $A(p,ω)$ we determine the quasiparticle spectrum, which can be accurately parametrized by three functions of temperature: an effective mass $m^*$, a mean-field potential $U$, and a gap $Δ$. Below the critical temperature $T_c=0.15\varepsilon_F$ the results for $m^*$, $U$ and $Δ$ can be accurately reproduced using an independent quasiparticle model. We find evidence of a pseudogap in the fermionic excitation spectrum for temperatures up to {$T^*\approx 0.20\varepsilon_{F} > T_c$}.
