description: In this paper, we construct full amplitude non-linear hydrodynamical models of fundamental mode Galactic Cepheids and analyze the resulting theoretical period-colour and amplitude-colour relations at maximum, mean and minimum light. These theoretical relations match the general form of the observed relations well. This agreement is, to some extent, independent of the mass-luminosity relations used, pulsation code, numerical techniques, details of the input physics and methods to convert theoretical quantities, such as bolometric luminosity and temperature, to observational quantities, such as V band magnitudes or $(V-I)$ colours. We show that the period-colour and amplitude-colour properties of fundamental mode Galactic Cepheids with periods such that $\log (P)>0.8$ can be explained by a simple application of the Stefan-Boltzmann law and the interaction of the photosphere with the hydrogen ionization front. We discuss the implications of our results for explaining the behavior of Galactic Cepheid period-colour, and period-luminosity relations at mean light.

description: Mappings between fermions and qubits are valuable constructions in physics. To date only a handful exist. In addition to revealing dualities between fermionic and spin systems, such mappings are indispensable in any quantum simulation of fermionic physics on quantum computers. The number of qubits required per fermionic mode, and the locality of mapped fermionic operators strongly impact the cost of such simulations. We present a novel fermion to qubit mapping which outperforms all previous local mappings in both the qubit to mode ratio, and the locality of mapped operators.

description: The relation between low energy CP violating phases, and the CP asymmetry of leptogenesis, $ε$, is investigated. Although it is known that in general those are independent, there may be a relation when a model is specified. We construct a Jarlskog invariant which is proportional to $ε$ if the right-handed neutrino masses are hierarchical. Since the invariant can be expressed in terms of left-handed neutrino parameters--some measurable, and some not--it is useful in identifying the limits in which $ε$ is related to MNS phases.

IMPACT OF THE OIL SECTOR ON THE DEVELOPMENT OF THE NON-OIL ECONOMY OF SAUDI ARABIA
Creators: name: Aldoasary, Fahad Saad
Publisher: name: American University
Year: 2023

description: The purpose of this study is to evaluate the impact of oil export expansion on the development of the non-oil economy of Saudi Arabia during the 1963-80 period. The primary aim of the study is to analyze the pattern of growth and the character of structural transformation of the non-oil economy during the period, with particular focus on the domestic manufacturing sector. The study used Hirschman's generalized linkage approach. The analytical tools of this approach consist of the well-known backward and forward linkages. These were used to analyze the direct and indirect linkage effects of the oil sector on the domestic economy. The approach includes also the "fiscal" and "consumption" linkages. The fiscal linkage measures the effects of government investment, while the consumption linkage measures the effects of the investment and production activities of the non-oil manufacturing sector. The linkage definitions were adapted to account for the lack of an input-output table and data limitations. To analyze the leakages in the oil stimulus, some leakage indicators were used. The study also used historical analysis to explain some non-economic aspects of the transformation. The main conclusions of the study are as follows: (1) A rapid growth of income and consumption and a significant improvement in the standard of living took place during the period of the study. (2) The backward and forward linkages as well as the consumption linkage were found to be weak relative to the fiscal linkage. The latter linkage, broadly defined, i.e., including the infrastructural investment, was very strong. But more narrowly defined--excluding the infrastructure and oil processing--the fiscal linkage was somewhat weak, though stronger than the other linkages. (3) The main trends of the economy generally were contrary to the expectation of the diversification strategy. The dependence of the non-oil economy on oil revenues has increased; the share of imports in total commodity supply has also increased; the share of domestic manufacturing in non-oil value-added has remained constant, while that of agriculture has declined; and the proportion of non-Saudis in the labor force has risen.

description: The periodic Anderson model (PAM) captures the essential physics of heavy fermion materials. Yet even for the paramagnetic metallic phase, a practicable many-body theory that can simultaneously handle all energy scales while respecting the dictates of Fermi liquid theory at low energies, and all interaction strengths from the strongly correlated Kondo lattice through to weak coupling, has remained quite elusive. Aspects of this problem are considered in the present paper where a non-perturbative local moment approach (LMA) to single-particle dynamics of the asymmetric PAM is developed within the general framework of dynamical mean-field theory. All interaction strengths and energy scales are encompassed, although our natural focus is the Kondo lattice regime of essentially localized $f$-spins but general conduction band filling, characterised by an exponentially small lattice coherence scale $ω_{L}$. Particular emphasis is given to the resultant universal scaling behaviour of dynamics in the Kondo lattice regime as an entire function of $ω^{\prime} =ω/ω_{L}$, including its dependence on conduction band filling, $f$-level asymmetry and lattice type.A rich description arises, encompassing both coherent Fermi liquid behaviour at low-$ω^{\prime}$ and the crossover to effective single-impurity scaling physics at higher energies -- but still in the $ω/ω_{L}$-scaling regime, and as such incompatible with the presence of two-scale `exhaustion' physics, which is likewise discussed.

A STUDY OF THE EFFECT OF THE D.C. PUBLIC SCHOOLS' HUMANISTIC STUDIES PROGRAM ON THE COLLEGE-BOUND STUDENT'S ADJUSTMENT AS A FRESHMAN (DISTRICT OF COLUMBIA)
Creators: name: Berryman-Miller, Sherill Diane
Publisher: name: American University
Year: 2023

description: This study examined the extent to which students made successful first-year transition in college after completing the Humanistic Studies Program offered in the D.C. Public Schools. The research evaluated the skills and techniques of the individual in the H. D. Woodson Humanistic Studies Program as it contributed to the student's abilities to: (1) Develop a structure to complete the academic work in college; (2) Select social activities with an impact on college adjustment; and (3) Interact with peers and professors in the college environment. The fifty students in the experimental group were graduates of H. D. Woodson Humanistic Studies Program with the 1980 and 1981 classes. The forty-five students in the control group were randomly selected from the graduating classes of 1980 and 1981 by their grade point average of B or better, SAT verbal score of at least 600 and attendance at a college or university. The subjects responded to the College Student Experience Questionnaire developed by C. Robert Pace in the Laboratory for Research on Higher Education at UCLA and an Informed Consent Form. MANOVA was used to analyze the humanities and non-humanities students' responses. An analysis of variance was used to check for differences between students with varying levels of preparation for the college experience components. The null hypotheses of no significant differences in the mean score of the humanities and non-humanities group on course learning, experience in writing, library experiences, use of the athletic and recreation facilities, participation in the arts, clubs, organizations and student union, experiences with faculty, personal experiences and acquaintances, conversational topics and information, opinions about college and estimates of gains were rejected. No significant differences were found between the experimental group and control group on the topics of conversation and opinions on college components. Related studies in the area of academic, interpersonal, cultural and social skills and techniques developed during high school and the student's ability to adjust to the college experiences support the findings. Further research is indicated in order to assess the influence and importance of high school performance on the results of topics of conversation and opinions about college.

description: We report an efficient technique to induce gate-tunable two-dimensional superlattices in graphene by the combined action of a back gate and a few-layer graphene patterned bottom gate complementary to existing methods. The patterned gates in our approach can be easily fabricated and implemented in van der Waals stacking procedures allowing flexible use of superlattices with arbitrary geometry. In transport measurements on a superlattice with lattice constant $a=40$ nm well pronounced satellite Dirac points and signatures of the Hofstadter butterfly including a non-monotonic quantum Hall response are observed. Furthermore, the experimental results are accurately reproduced in transport simulations and show good agreement with features in the calculated band structure. Overall, we present a comprehensive picture of graphene-based superlattices, featuring a broad range of miniband effects, both in experiment and in theoretical modeling. The presented technique is suitable for studying more advanced geometries which are not accessible by other methods.

description: Death of a parent during adolescence may damage the adolescent's development by hindering the normal emotional processes leading to adulthood (Laufer, 1964). If the adolescent does not mourn it can have a deleterious effect on the quality of the relationships formed by the adult in later life (Fleming & Altschul, 1963). This study was designed to investigate the relationship between completion of the grieving process, selected family variables, and the quality of heterosexual relationships in women who lost their fathers during adolescence. The relationships between these variables and the grief process were examined through the use of hierarchical and stepwise multiple regression analyses. The study employed an ex post facto correlational design with completion of the grieving process, measured by the Modified Grief Work Survey, and attitudes toward family, measured by the Family Adjustment Test, as the independent variables. The Caring Relationship Inventory (Shostrum, 1966) and the Quality of Relationship Questionnaire (Kleinberg, 1982) were the dependent variables. Subjects were 30 women college students presently in relationships for at least one year or more who lost their fathers during adolescence. They were from three universities in New York City: Pace University, New York University, and Fordham University. Each subject volunteered to participate in the study during the Fall 1982 semester. The findings indicated that the more unresolved oedipal and attachment feelings the women have in relationship to their fathers, the greater discrepancy there is between their ideal and present partner. Also, it was found that completion of the grieving process was not significantly related to the quality of heterosexual relationships. Neither the Caring Relationship Inventory nor the Quality of Relationship Questionnaire correlated significantly with the Modified Grief Work Survey. The Modified Grief Survey did correlate significantly with the expression of emotions in the subject's present heterosexual relationship. That is, a relatively quick and total completion of the grief process was associated with frequent expression of emotion by the women in their current relationships. Methodological considerations and problems regarding the measures were discussed. Recommendations were made regarding the need for further research.

description: We demonstrate the utility of the numerical Contractor Renormalization (CORE) method for quantum spin systems by studying one and two dimensional model cases. Our approach consists of two steps: (i) building an effective Hamiltonian with longer ranged interactions using the CORE algorithm and (ii) solving this new model numerically on finite clusters by exact diagonalization. This approach, giving complementary information to analytical treatments of the CORE Hamiltonian, can be used as a semi-quantitative numerical method. For ladder type geometries, we explicitely check the accuracy of the effective models by increasing the range of the effective interactions. In two dimensions we consider the plaquette lattice and the kagome lattice as non-trivial test cases for the numerical CORE method. On the plaquette lattice we have an excellent description of the system in both the disordered and the ordered phases, thereby showing that the CORE method is able to resolve quantum phase transitions. On the kagome lattice we find that the previously proposed twofold degenerate S=1/2 basis can account for a large number of phenomena of the spin 1/2 kagome system. For spin 3/2 however this basis does not seem to be sufficient anymore. In general we are able to simulate system sizes which correspond to an 8x8 lattice for the plaquette lattice or a 48-site kagome lattice, which are beyond the possibilities of a standard exact diagonalization approach.

Stål (1863) gave Manila on the Luzon Island as the type locality; however, lacking any additional records from Luzon, this seems to be a mistaken locality (see also Taeuber 1927). The record from Malaysia: Pinang Island (Schmidt 1932, as Pulo Penang) is apparently a misidentification.
 Note. Dindymus vinulus is morphologically variable species and it is quite possible that some of the island population will deserve subspecific status. To avoid later confusions, I am referring to the typical form as D. vinulus vinulus.

description: Consider the zero set of the random power series f(z)=sum a_n z^n with i.i.d. complex Gaussian coefficients a_n. We show that these zeros form a determinantal process: more precisely, their joint intensity can be written as a minor of the Bergman kernel. We show that the number of zeros of f in a disk of radius r about the origin has the same distribution as the sum of independent {0,1}-valued random variables X_k, where P(X_k=1)=r^{2k}. Moreover, the set of absolute values of the zeros of f has the same distribution as the set {U_k^{1/2k}} where the U_k are i.i.d. random variables uniform in [0,1]. The repulsion between zeros can be studied via a dynamic version where the coefficients perform Brownian motion; we show that this dynamics is conformally invariant.

Conservative finite-volume framework and pressure-based algorithm for flows of incompressible, ideal-gas and real-gas fluids at all speeds

description: A conservative finite-volume framework, based on a collocated variable arrangement, for the simulation of flows at all speeds, applicable to incompressible, ideal-gas and real-gas fluids is proposed in conjunction with a fully-coupled pressure-based algorithm. The applied conservative discretisation and implementation of the governing conservation laws as well as the definition of the fluxes using a momentum-weighted interpolation are identical for incompressible and compressible fluids, and are suitable for complex geometries represented by unstructured meshes. Incompressible fluids are described by predefined constant fluid properties, while the properties of compressible fluids are described by the Noble-Abel-stiffened-gas model, with the definitions of density and specific static enthalpy of both incompressible and compressible fluids combined in a unified thermodynamic closure model. The discretised governing conservation laws are solved in a single linear system of equations for pressure, velocity and temperature. Together, the conservative finite-volume discretisation, the unified thermodynamic closure model and the pressure-based algorithm yield a conceptually simple, but versatile, numerical framework. The proposed numerical framework is validated thoroughly using a broad variety of test-cases, with Mach numbers ranging from 0 to 239, including viscous flows of incompressible fluids as well as the propagation of acoustic waves and transiently evolving supersonic flows with shock waves in ideal-gas and real-gas fluids. These results demonstrate the accuracy, robustness and the convergence, as well as the conservation of mass and energy, of the numerical framework for flows of incompressible and compressible fluids at all speeds, on structured and unstructured meshes.

AN EXPERIMENTAL TEST OF ISING-MODEL PREDICTIONS OF THE BEHAVIOR OF CARBON DIOXIDE NEAR THE CRITICAL POINT
Creators: name: Madison, David Lee
Publisher: name: American University
Year: 2023

description: Ising-model calculations by Howard Tarko and Michael Fisher predict that contours of constant susceptibility and constant correlation length are incongruous in the vicinity of the critical point, i.e., (chi) r('-(gamma)) while (xi) r('-(nu))(1 + 0.17(theta)('2)), where r and (theta) are restricted cubic-model parameters. An experiment using an optical probe (a focused, vertically polarized helium-neon laser beam) to measure the susceptibility and correlation length of carbon dioxide near the critical point was devised to test this prediction. The experiments were conducted over the temperature range -2.2 mK < (DELTA)T < 14.5 mK. The susceptibility as a function of temperature and height in the fluid was determined by measuring the vertical deflection of the optical probe. The correlation length was determined by constructing Ornstein-Zernike plots based on measurements of horizontal-scattering intensities. The horizontal-scattering data were corrected for attenuation and for double scattering. An independent measurement of the fluid's turbidity provided a cross-check of the susceptibility and correlation-length measurements. The experimental data resulting from this research were analyzed in two ways. First, the cubic-model parameters r and (theta) were estimated from the height of the optical probe in the fluid and the estimated temperture difference T - T(,c). Next, the same parameters were estimated, with slightly different results, using the height of the optical probe and the measured susceptibility. The measured values of the correlation length were interpreted using the Tarko-Fisher critical-scattering function. The result, using the first method of estimating r and (theta), is that the correlation length can be represented by (xi) = 0.141 r('-0.63) (1 + 0.12(theta)('2)), with a RMS deviation of 3.0%. The result using the second method of calculating r and (theta) is that (xi) = 0.139 r('-0.63) (1 + 0.16(theta)('2)), with a RMS deviation of 1.7%. These experimental results lead to the conclusion that the Tarko-Fisher predictions accurately portray the incongruity of the susceptibility and correlation-length contours as well as the scattering function near the critical point.

description: We give an explicit characterisation of the quantum states which saturate the strong subadditivity inequality for the von Neumann entropy. By combining a result of Petz characterising the equality case for the monotonicity of relative entropy with a recent theorem by Koashi and Imoto, we show that such states will have the form of a so-called short quantum Markov chain, which in turn implies that two of the systems are independent conditioned on the third, in a physically meaningful sense. This characterisation simultaneously generalises known necessary and sufficient entropic conditions for quantum error correction as well as the conditions for the achievability of the Holevo bound on accessible information.

description: Ising-model calculations by Howard Tarko and Michael Fisher predict that contours of constant susceptibility and constant correlation length are incongruous in the vicinity of the critical point, i.e., (chi) r('-(gamma)) while (xi) r('-(nu))(1 + 0.17(theta)('2)), where r and (theta) are restricted cubic-model parameters. An experiment using an optical probe (a focused, vertically polarized helium-neon laser beam) to measure the susceptibility and correlation length of carbon dioxide near the critical point was devised to test this prediction. The experiments were conducted over the temperature range -2.2 mK < (DELTA)T < 14.5 mK. The susceptibility as a function of temperature and height in the fluid was determined by measuring the vertical deflection of the optical probe. The correlation length was determined by constructing Ornstein-Zernike plots based on measurements of horizontal-scattering intensities. The horizontal-scattering data were corrected for attenuation and for double scattering. An independent measurement of the fluid's turbidity provided a cross-check of the susceptibility and correlation-length measurements. The experimental data resulting from this research were analyzed in two ways. First, the cubic-model parameters r and (theta) were estimated from the height of the optical probe in the fluid and the estimated temperture difference T - T(,c). Next, the same parameters were estimated, with slightly different results, using the height of the optical probe and the measured susceptibility. The measured values of the correlation length were interpreted using the Tarko-Fisher critical-scattering function. The result, using the first method of estimating r and (theta), is that the correlation length can be represented by (xi) = 0.141 r('-0.63) (1 + 0.12(theta)('2)), with a RMS deviation of 3.0%. The result using the second method of calculating r and (theta) is that (xi) = 0.139 r('-0.63) (1 + 0.16(theta)('2)), with a RMS deviation of 1.7%. These experimental results lead to the conclusion that the Tarko-Fisher predictions accurately portray the incongruity of the susceptibility and correlation-length contours as well as the scattering function near the critical point.

description: Research background: The threat from climate change remains a major concern especially for developing economies like Ghana. Hence, agricultural practices that are environmentally friendly and improves soil health are very necessary for building resilience. Purpose of the article: The present study investigated the determinants of conservation agricultural practices in northern Ghana as well as the effect of these practices on soil health for sustainable production. Methods: Using cross-sectional data collected by the International food policy research institute from 1284 households, a multivariate probit model was first performed to identify the determinants of conservation agricultural practices while the inverse probability weighted regression adjustment was employed to establish the effect of conservation agricultural practices on soil health. Findings & value added: Results from the multivariate probit model showed that socioeconomic and institutional factors as well as different household-specific factors, influence farmer’s decisions to engage in various conservation agricultural practices. Crop rotation, fallowing, contour ploughing or pit planting and manure application were found to have a positive effect on soil health through improved resilience to soil erosion. The study concludes that conservation agricultural practices will be useful in Ghana’s quest of achieving zero hunger since the conservation agricultural practices ensure that food is produced for the present generations without compromising the soil health for further productions. Hence, the current Ghanaian government’s flagship programme dubbed ‘planting for food and jobs’ should include conservation agriculture as a priority module in its framework so that households could both increase their output while maintaining the quality of the soil.

description: A prototypical model of a one-dimensional metallic monatomic solid containing noninteracting electrons is studied, where the argument of the cosine potential energy periodic with the lattice contains the first reciprocal lattice vector G1 = 2pi/a, where a is the lattice constant. The time-independent Schrodinger equation can be written in reduced variables as a Mathieu equation for which numerically-exact solutions for the band structure and wave functions are obtained. The band structure has band gaps that increase with increasing amplitude q of the cosine potential. In the extended-zone scheme, the energy gaps decrease with increasing index n of the Brillouin-zone boundary ka = n pi where k is the crystal momentum of the electron. The wave functions at the bottoms and tops of the bands are found to be real or imaginary, respectively, corresponding to standing waves at these energies. Irrespective of the wave vector k within the first Brillouin zone, the electron probability density is found to be periodic with the lattice. The Fourier components of the wave functions are derived versus q, which reveal multiple reciprocal-lattice-vector components with variable amplitudes in the wave functions unless q = 0. The magnitudes of the Fourier components are found to decrease exponentially as a power of n for n ~ 3 to 45 for ka = pi/2 and q = 2 and a precise fit is obtained to the data. The probability densities and probability currents obtained from the wave functions are also discussed. The probability currents are found to be zero for crystal momenta at the tops and bottoms of the energy bands, because the wave functions for these crystal momenta are standing waves. Finally, the band structure is calculated from the central equation and compared to the numerically-exact band structure.

Supermassive Stars in Quasar Disks

description: We propose that supermassive stars may form in quasar accretion disks, and we discuss possible observational consequences. The structure and stability of very massive stars are reviewed. Because of high accretion rates, quasar disks are massive and the fringes of their optically luminous parts are prone to fragmentation. Starting from a few hundred solar masses, a dominant fragment will grow to the isolation mass, which is a significant fraction of the disk mass, more quickly than the fragment contracts onto the stellar main sequence. A gap will form in the disk and the star will migrate inward on the accretion timescale, which is comparable to the star's main sequence lifetime. By interrupting the gas supply to the inner disk, the gap may temporarily dim and redden the quasar. The final stages of stellar migration will be a strong source of low-frequency gravitational waves.

FACTORS CONTRIBUTING TO THE RESPONSE RATES MAINTAINED BY VARIABLE-RATIO AND VARIABLE-INTERVAL SCHEDULES OF REINFORCEMENT
Creators: name: Peele, David Bray
Publisher: name: American University
Year: 2023

description: In a series of four experiments, response rates maintained under multiple variable-ratio variable-interval schedules were examined using a within-subject yoke-design that equated between-component reinforcement rates. Two features proposed to control higher rates of responding during the variable-ratio schedule were independently manipulated. They were (1) the role of the reinforced interresponse time, and (2) the function relating response rate and rate of reinforcement. Collectively, the results of the four experiments point to the primacy of IRT reinforcement in shaping higher response rates under the variable-ratio schedule, thereby supporting molecular over molar accounts of response-rate effects.
Quantum interference in resonant tunneling and single spin measurements

description: We consider the resonant tunneling through a multi-level system. It is demonstrated that the resonant current displays quantum interference effects due to a possibility of tunneling through different levels. We show that the interference effects are strongly modulated by a relative phase of states carrying the current. This makes it possible to use these effects for measuring the phase difference between resonant states in quantum dots. We extend our model for a description of magnetotransport through the Zeeman doublets. It is shown that, due to spin-flip transitions, the quantum interference effects generate a distinct peak in the shot-noise power spectrum at the frequency of Zeeman splitting. This mechanism explains modulation in the tunneling current at the Larmor frequency observed in scanning tunneling microscope experiments and can be utilized for a single spin measurement.
