description: The current study examined the effects of a values-based intervention on college student performance, and was the first known study to investigate the impact of the intervention on college student retention. Given their increased likelihood of experiencing identity and belongingness threats in the college environment, of specific interest was whether the intervention would be especially beneficial for underrepresented minorities, including students of color and first-generation students. This study did not replicate previous findings indicating that writing about personal values in the experimental condition improved academic performance among minorities. Indeed, there was a marginal effect of the intervention on fall semester GPA, such that participants who wrote about others’ values in the control condition obtained higher GPAs than participants in the experimental condition – particularly among minorities. Minority controls also scored marginally higher on a post-intervention measure of authenticity than minorities in the experimental condition, controlling for baseline levels of the construct. No condition- or group-based differences in sense of belonging were observed, and neither authenticity nor sense of belonging were found to mediate the effects of the intervention. Academic competence contingency of self-worth was not found to moderate the effects of the intervention. The intervention was not found to impact fall semester credits, the index of college student persistence used in this study. Study limitations and future directions are discussed.

description: In this paper, we present a new performance bound for uplink channel estimation (CE) accuracy in the Massive Multiple Input Multiple Output (MIMO) system. The proposed approach is based on noise power prediction after the CE unit. Our method outperforms the accuracy of a well-known Cramer-Rao lower bound (CRLB) due to considering more statistics since performance strongly depends on a number of channel taps and power ratio between them. Simulation results are presented for the non-line of sight (NLOS) 3D-UMa model of 5G QuaDRiGa 2.0 channel and compared with CRLB and state-of-the-art CE algorithms.

Radon as a natural tracer of gas transport through trees

Publisher: name: American University
Year: 2023

description: Trees are sources, sinks, and conduits for gas exchange between the atmosphere and soil, and effectively link these terrestrial realms in a soil–plant–atmosphere continuum. We demonstrated that naturally produced radon-222 (222Rn) gas has the potential to disentangle the biotic and physical processes that regulate gas transfer between soils or plants and the atmosphere in field settings where exogenous tracer applications are challenging. Patterns in stem radon emissions across tree species, seasons, and diurnal periods suggest that plant transport of soil gases is controlled by plant hydraulics, whether by diffusion or mass flow via transpiration. We establish for the first time that trees emit soil gases during the night when transpiration rates are negligible, suggesting that axial diffusion is an important and understudied mechanism of plant and soil gas transmission.

description: We study the four-terminal resistance fluctuations of mesoscopic samples near the transition between the $ν=2$ and the $ν=1$ quantum Hall states. We observe near-perfect correlations between the fluctuations of the longitudinal and Hall components of the resistance. These correlated fluctuations appear in a magnetic-field range for which the two-terminal resistance of the samples is quantized. We discuss these findings in light of edge-state transport models of the quantum Hall effect. We also show that our results lead to an ambiguity in the determination of the width of quantum Hall transitions.

description: The purpose of this research is to investigate the effect of Pistachio Shell powder on some properties of (heatcure)PMMA acrylic resin that’s popularly used as denture base material, where this natural powder had been add indifferent weight fraction (3, 6, 9, and 12 wt. %) and different average particle size (53μm, 106μm, 150μm, and 212μm).Tensile and SEM test had been studied, the results where statistically analyzed by using SPSS (one-way ANOVA)program to evaluate the mean value and show the significant difference for each particle size. The results were as the following: the tensile strength and elongation percentage were dropped with increasing the weight the weight of Pistachio Shell powder, while the Young’s modulus had been increased with increasing the weight fraction of Pistachio Shell powder and reached its maximum value at (12 wt. %) of average particle size (53μm). SEM results show that the smoothness of fractured surface will increase and that is suggesting a brittle to semi ductile transformation.

description: Comets are small bodies thought to contain the most pristine material in the solar system. However, since their formation ≈4.5 Gy ago, they have been altered by different processes. While not exposed to much electromagnetic radiation, they experience intense particle radiation. Galactic cosmic rays and solar energetic particles have a broad spectrum of energies and interact with the cometary surface and subsurface; they are the main source of space weathering for a comet in the Kuiper Belt or in the Oort Cloud, and also affect the ice prior to the comet agglomeration. While low-energy particles interact only with the cometary surface, the most energetic ones deposit a significant amount of energy down to tens of meters. This interaction can modify the isotopic ratios in cometary ices and create secondary compounds through radiolysis, such as O2 and H2O2 (Paper II). In this paper, we model the energy deposition of energetic particles as a function of depth using a Geant4 application modified to account for the isotope creation process. We quantify the energy deposited in cometary nucleus by galactic cosmic rays and solar energetic particles. The consequences of the energy deposition on the isotopic and chemical composition of cometary ices and their implication on the interpretation of cometary observations, notably of 67P/Churyumov Gerasimenko by the ESA Rosetta spacecraft, will be discussed in Paper II.

description: Nuclear Magnetic Resonance studies of Ga stabilized delta-Pu reveal detailed information about the local distortions surrounding the Ga impurities as well as provides information about the local spin fluctuations experienced by the Ga nuclei. The Ga NMR spectrum is inhomogeneously broadened by a distribution of local electric field gradients (EFGs), which indicates that the Ga experiences local distortions from cubic symmetry. The Knight shift and spin lattice relaxation rate indicate that the Ga is dominantly coupled to the Fermi surface via core polarization, and is inconsistent with magnetic order or low frequency spin correlations.

description: MatBase is a prototype intelligent data and knowledge base management system based on the Relational, Entity-Relationship, and (Elementary) Mathematical Data Models. The latter distinguishes itself especially by its rich panoply of constraint types: 61, partitioned into three categories (set, containing 16 types, mapping, containing 44 types, and object) and eight subcategories (general set, dyadic relation, general mapping, autofunction, general function product, homogeneous binary function product, function diagram, and object). They provide database and software application designers with the tools necessary for capturing and enforcing all business rules from any subuniverse of discourse, thus guaranteeing database instances plausibility, a sine qua non condition of data quality. This mathematical data model also includes Datalog, thus making MatBase also a deductive, so a knowledge base system. Currently, there are two MatBase versions (one developed in MS Access and the other in MS .NET, using C# and SQL Server), used by two software developing companies, as well as during labs of our M.Sc. students with the Advanced Databases lectures and labs, both at the Ovidius University at Constanta and at the Department of Engineering in Foreign Languages, Computer Science Taught in English Stream of the Bucharest Polytechnic University. This paper presents MatBase's metadata catalog and its management.

description: Context. Due to the effects that they can have on the atmospheres of exoplanets, stellar winds have recently received significant attention in the literature. Alfvén-wave-driven 3D magnetohydrodynamic models, which are increasingly used to predict stellar wind properties, contain unconstrained parameters and rely on low-resolution stellar magnetograms. Aims. In this paper, we explore the effects of the input Alfvén wave energy flux and the surface magnetogram on the wind properties predicted by the Alfvén Wave Solar Model (AWSoM) model for both the solar and stellar winds. Methods. We lowered the resolution of two solar magnetograms during solar cycle maximum and minimum using spherical harmonic decomposition. The Alfvén wave energy was altered based on non-thermal velocities determined from a far ultraviolet spectrum of the solar twin 18 Sco. Additionally, low-resolution magnetograms of three solar analogues, 18 Sco, HD 76151, and HN Peg, were obtained using Zeeman Doppler imaging and used as a proxy for the solar magnetogram. Finally, the simulated wind properties were compared to Advanced Composition Explorer (ACE) observations. Results. AWSoM simulations using well constrained input parameters taken from solar observations can reproduce the observed solar wind mass loss and angular momentum loss rates. The simulated wind velocity, proton density, and ram pressure differ from ACE observations by a factor of approximately two. The resolution of the magnetogram has a small impact on the wind properties and only during cycle maximum. However, variation in Alfvén wave energy influences the wind properties irrespective of the solar cycle activity level. Furthermore, solar wind simulations carried out using the low-resolution magnetogram of the three stars instead of the solar magnetogram could lead to an order of a magnitude difference in the simulated solar wind properties. Conclusions. The choice in Alfvén energy has a stronger influence on the wind output compared to the magnetogram resolution. The influence could be even stronger for stars whose input boundary conditions are not as well constrained as those of the Sun. Unsurprisingly, replacing the solar magnetogram with a stellar magnetogram could lead to completely inaccurate solar wind properties, and should be avoided in solar and stellar wind simulations. Further observational and theoretical work is needed to fully understand the complexity of solar and stellar winds.
Scaled variables and the quark-hadron duality

description: The thermodynamic quantities of the ideal gas of hadrons and the $(2+1)$--flavor lattice QCD scaled by the effective degeneracy factors of the corresponding models are compared. We have found that in terms of the scaled variables the quark-hadron duality of the lattice QCD and the hadron resonance gas (HRG) model disappears. However, we have unexpectedly revealed that the scaled variables lead to the quark-hadron duality of the lattice QCD and the quantum ideal gas of kaons and antikaons, namely, the ideal gas of those hadrons that contain all the three quarks $u,d,s$ and their antiquarks. Satisfactory agreement between the scaled results of the kaon ideal gas and the lattice QCD data is achieved at large values of the volume in the entire temperature range. In the ideal gas of kaons there is no any phase transition. Nevertheless, in our calculations the scaled thermodynamic quantities of the ideal gas and the lattice QCD follow the same qualitative behavior and are consistent with each other especially at high temperatures in the perturbative region.

Resolving the excess of long GRB's at low redshift in the Swift era
Creators: name: Le, Truong

Publisher: name: American University
Year: 2023

description: Utilizing more than 100 long gamma-ray bursts (LGRBs) in the Swift-Ryan-2012 sample that includes the observed redshifts and jet angles, Le & Mehta performed a timely study of the rate density of LGRBs with an assumed broken power-law GRB spectrum and obtained a GRB-burst-rate functional form that gives acceptable fits to the pre-Swift and Swift redshift, and jet angle distributions. The results indicated an excess of LGRBs at redshift below z ∼ 2 in the Swift sample. In this work, we are investigating if the excess is caused by the cosmological Hubble constant H0, the gamma-ray energy released ϵ∗γ, the low- and high-energy indices (α, β) of the Band function, the minimum and maximum jet angles Θj, min and Θj, max, or that the excess is due to a bias in the Swift-Ryan-2012 sample. Our analyses indicate that none of the above physical parameters resolved the excess problem, but suggesting that the Swift-Ryan-2012 sample is biased with possible afterglow selection effect. The following model physical parameter values provide the best fit to the Swift-Ryan-2012 and pre-Swift samples: the Hubble constant H0 = 72 kms-1Mpc-1, the energy released ϵ∗γ ∼ 4.47 × 1051 erg, the energy indices α ∼ 0.9 and β ∼-2.13, the jet angles of Θj, max ∼ 0.8 rad, and Θj, min ∼ 0.065 and ∼0.04 rad for pre-Swift and Swift, respectively, s∼-1.55 the jet angle power-law index, and a GRB formation rate that is similar to the Hopkins & Beacom observed star formation history and as extended by Li. Using the Swift Gamma-Ray Burst Host Galaxy Legacy Survey (SHOALS) Swift-Perley LGRB sample and applying the same physical parameter values as above, however, our model provides consistent results with this data set and indicating no excess of LGRBs at any redshift.
Scalar effective potential for D7 brane probes which break chiral symmetry

description: We consider D7 brane probes embedded in deformed AdS5 x S5 supergravity backgrounds which are non-supersymmetric in the interior. In the context of the generalised AdS/CFT correspondence, these setups are dual to QCD-like theories with fundamental matter which display chiral symmetry breaking by a quark condensate. Evaluating the D7 action for a surface instanton configuration gives rise to an effective potential for the scalar Higgs vev in the dual field theory. We calculate this potential for two specific supergravity backgrounds. For a metric due to Constable and Myers, we find that the potential is asymptotically bounded by a 1/Q^4 behaviour and has a minimum at zero vev. For the Yang-Mills* background we find that the Higgs potential scales quadratically with the Higgs vev. This corresponds to a canonical mass term and the embedding is again stable.

description: Recent empirical work has questioned the consistency of U.S. fiscal policy with an intertemporal budget constraint. Empirical results have tended to indicate that the deficit process has undergone at least one structural shift during recent decades, with the deficit becoming either unsustainable or sustainable in only a weak sense in the postshift period. In this paper, we re-examine sustainability using a new approach, based on a cointegration model with multiple endogenous breaks. A Bayesian methodology is applied, incorporating Markov chain Monte Carlo simulators. In contrast to previous analyses, we find evidence of a sustainable deficit process over the 1947 to 1992 period, despite the occurrence of breaks during the 1970's and 1980's.
Corrective policy reactions : positive and negative budgetary punctuations

description: Punctuated equilibrium theory seeks to explain policy volatility and stability in government attention. In previous research into the temporal dynamics of punctuations, scholars found that punctuations occur in clusters - a recent budgetary punctuation increases the likelihood of a subsequent punctuation. This article examines the direction, positive or negative, of budgetary punctuations over time. Are budgetary punctuations corrective, grouping positive and negative changes? Or, do budgetary punctuations occur in cumulative trends of positive or negative changes? These questions address the heart of the theoretical metaphor for punctuated equilibrium. In an analysis of over 1,000 Texas school districts for nearly a 20-year-period, results support the notion of reactive patterns of budgetary punctuations - positive and negative budgetary punctuations pair up at a rate much higher than expected by chance. The findings demonstrate that even though it is likely to see consecutive positive and negative punctuations, they are not always fully corrective.

Bright field and matching fluorescent images of cultured mouse DRG neurons infected with SARM1-EGFP constructs including the human reference allele, every constitutively active SARM1 variant found in ALS patients and ten rare SARM1 variants found in controls. The expression of EGFP in neurons infected with ALS-associated constitutively active SARM1 variants is similar or less than EGFP expression in reference SARM1-infected neurons (compare background fluorescence to cell bodies).
Radio halos in star forming galaxies

description: We study the relation between radio halos, the energy input by supernovae in the disk and the galaxy mass. We find that both the energy input by supernovae as well as the galaxy mass are important parameters for understanding the formation of radio halos. Galaxies with a high energy input by supernovae per star forming area and a low galaxy mass generally possess radio halos whereas galaxies with the opposite characteristics do not. Furthermore, there is a tentative correlation between the observed scale height and the expected height in a simple gravitational approximation.

description: This paper estimates the long-term trends in the daily maxima of tropospheric ozone at six sites around the state of Texas. The statistical methodology we use controls for the effects of meteorological variables because it is known that variables such as temperature, wind speed and humidity substantially affect the formation of tropospheric ozone. A nonparametric regression model is estimated in which a general trivariate surface is used to model the relationship between ozone and these meteorological variables because there is little, or no, theory to specify the functional dependence of ozone on these variables. The model also allows for the effects of wind direction and seasonality. Each function in the model is represented as a linear combination of basis functions located at all of the design points. A trivariate basis is used for the function representing the combined effect of temperature, wind speed and humidity, while univariate bases are used to represent the other functions in the model. To estimate the functions nonparametrically we use a Bayesian hierarchical framework with a fractional prior. Due to the high dimensional representation of the signal, a Markov chain Monte Carlo sampling scheme employing Gibbs sub-chains that 'focus' on the basis terms that are most likely to contribute to the signal is used to carry out the computations. We also estimate an appropriate data transformation simultaneously with the function estimates. The empirical results indicate that key meteorological variables explain most of the variation in daily ozone maxima through a nonlinear interaction and that their effects are consistent across the six sites. However, the estimated trends vary considerably from site to site, even within the same city. A simulation based on the design of the data indicates that the Bayesian approach is substantially more efficient than MARS (Friedman, 1991).

description: The focus of this paper is on the relationship between the exponential smoothing methods of forecasting and the integrated autoregressive-moving average models underlying them. In this paper we derive, for the first time, the general linear relationship between their parameters. A method, suitable for implementation on computer, is proposed to determine the pertinent quantities in this relationship. It is illustrated on common forms of exponential smoothing. It is also applied to a new seasonal form of exponential smoothing with seasonal indexes which always sum to zero.
QCD sum rule studies on the $s s \bar s \bar s$ tetraquark states of $J^{PC} = 0^{-+}$

description: We apply the method of QCD sum rules to study the $s s \bar s \bar s$ tetraquark states of $J^{PC} = 0^{-+}$. We construct all the relevant $s s \bar s \bar s$ tetraquark currents, and find that there are only two independent ones. We use them to further construct two weakly-correlated mixed currents. One of them leads to reliable QCD sum rule results and the mass is extracted to be $2.51^{+0.15}_{-0.12}$ GeV, suggesting that the $X(2370)$ or the $X(2500)$ can be explained as the $ss\bar s\bar s$ tetraquark state of $J^{PC} = 0^{-+}$. To verify this interpretation, we propose to further study the $ππ/K \bar K$ invariant mass spectra of the $J/ψ\to γππη^\prime/γK \bar K η^\prime$ decays in BESIII to examine whether there exists the $f_0(980)$ resonance.

description: Recent advances in computing power have brought the use of computer intensive estimation methods of binary panel data models within the reach of the applied researcher. The aim of this paper is to apply some of these techniques to a marketing data set and compare the results. In addition, their small sample performance is examined via Monte Carlo simulation experiments. The first estimation technique used was maximum likelihood estimation of the cross section probit (ignoring heterogeneity). The remaining .techniques estimated the binary panel probit model using: standard maximum likelihood; the Solomon-Cox approximation to this likelihood and finally; the Gibbs sampler to obtain Bayesian estimates. The results suggested that, in most cases, standard maximum likelihood estimation of the binary panel probit model was the preferred technique primarily because it is readily available to applied practitioners. Although when the variance of the heterogeneity term is small, the computational simplicity of the Solomon-Cox approximation may prove attractive. In large samples, the Gibbs sampler was also found to perform well.
Long lived acoustic vibrational modes of an embedded nanoparticle

description: Classical continuum elastic calculations show that the acoustic vibrational modes of an embedded nanoparticle can be lightly damped even when the longitudinal plane wave acoustic impedances $Z_o=ρv_L$ of the nanoparticle and the matrix are the same. It is not necessary for the matrix to be less dense or softer than the nanoparticle in order to have long lived vibrational modes. Continuum boundary conditions do not always accurately reflect the microscropic nature of the interface between nanoparticle and matrix, and a multi-layer model of the interface reveals the possibility of additional reduction of mode damping.

description: The psychometric properties of a revised version of the Marital Decision Making Scale (MDMS) were evaluated in this investigation. Sixty-eight couples served as participants. Distressed couples (n=34) were recruited from a community-based outpatient mental health clinic where they were seeking conjoint therapy for relationship problems; demographically matched nondistressed couples (n=34) were recruited from the community through a local survey research firm. The MDMS showed high internal consistency, test-retest reliability, interjudge agreement, and convergent and discriminant validity. A second independent sample of 60 couples (30 distressed couples and 30 nondistressed couples) was also recruited to cross-validate the results found with the first sample. Using the classification equation derived from the data for the first sample, the MDMS was found to reliably discriminate between distressed and nondistressed couples with this second sample. Potential clinical utility of the MDMS is reviewed.
