description: We study q-stars with one or two scalar fields, non-abelian, and fermion-scalar q-stars in 2+1 dimensions in an anti de Sitter or flat spacetime. We fully investigate their properties, such as mass, particle number, radius, numerically, and focus on the matter of their stability against decay to free particles and gravitational collapse. We also provide analytical solutions in the case of flat spacetime and other special cases.

description: Mean motion resonances are commonly seen in planetary systems, e.g., in the formation of orbital structure of Jupiter's moons and the gaps in the rings of Saturn. In this work we study their effects in fully relativistic systems. We consider a model problem with two stellar mass black holes orbiting around a supermassive black hole. By adopting a two time-scale expansion technique and averaging over the fast varying orbital variables, we derive the effective Hamiltonian for the slowly varying dynamical variables. The formalism is illustrated with a n'_phi : n'_r : n_phi= 2:1:-2 resonance in Schwarzschild spacetime, which naturally becomes the 3:2 resonance widely studied in the Newtonian limit. We also derive the multi-body Hamiltonian in the post-Newtonian regime, where the radial and azimuthal frequencies are different because of the post-Newtonian precession. The capture and breaking conditions for these relativistic mean motion resonances are also discussed. In particular, pairs of stellar mass black holes surrounding the supermassive black hole could be locked into resonances as they enter the LISA band, and this would affect their gravitational wave waveforms.

description: Current interferometric gravitational wave detectors use test masses with mirror coatings formed from multiple layers of dielectric materials, most commonly alternating layers of SiO2 (silica) and Ta2O5 (tantala). However, mechanical loss in the Ta2O5/SiO2 coatings may limit the design sensitivity for advanced detectors. We have investigated sources of mechanical loss in the Ta2O5/SiO2 coatings, including loss associated with the coating-substrate interface, with the coating-layer interfaces, and with the bulk material. Our results indicate that the loss is associated with the bulk coating materials and that the loss of Ta2O5 is substantially larger than that of SiO2.

description: In this work we study the evolution of a spatially flat Universe by considering a viscous dark matter and perfect fluids for dark energy and radiation, including an interaction term between dark matter and dark energy. In the first part, we analyse the general properties of the Universe by performing a stability analysis and then we constrain the free parameters of the model using the latest and cosmological-independent measurements of the Hubble parameter. We find consistency between the viscosity coefficient and the condition imposed by the second law of the Thermodynamics. The second part is dedicated to constrain the free parameter of the interacting viscous model (IVM) for three particular cases: the viscous model (VM), interacting model (IM), and the perfect fluid case (the concordance model). We report the deceleration parameter to be $q_0 = -0.54^{+0.06}_{-0.05}$, $-0.58^{+0.05}_{-0.04}$, $-0.58^{+0.05}_{-0.05}$, $-0.63^{+0.02}_{-0.02}$, together with the jerk parameter as $j_0 = 0.87^{+0.06}_{-0.09}$, $0.94^{+0.04}_{-0.06}$, $0.91^{+0.06}_{-0.10}$, $1.0$ for the IVM, VM, IM, and LCDM respectively, where the uncertainties correspond at 68\% CL. Worth mentioning that all the particular cases are in good agreement with LCDM, in some cases producing even better fits, with the advantage of eliminating some problems that afflicts the standard cosmological model.

title: An Evaluation of Authenticity: A Content Analysis of K-6 Mandarin Matrix Textbooks for Chinese Dual Language Immersion Programs
Creators: name: Tsai, Hsiaomei
Publisher: name: Utah State University
Year: 2024

description: Authentic texts are suggested for building practical language skills that go beyond the classroom, helping language learners to communicate with native speakers. This study used content analysis and a teacher survey to examine how the Utah Chinese Dual Language Immersion (DLI) literacy curriculum, featuring the Grades K-6 Mandarin Matrix textbooks, reflects realistic Chinese language and culture. Additionally, this study explored the pedagogical value of these textbooks in Utah’s Chinese DLI programs via a teacher survey. The results showed high linguistic authenticity in word usage, order, and situations, consistently above 99% across Grades K to 6 books. Cultural authenticity, particularly in scenarios and characters’ behaviors, exceeded 95%. However, settings (e.g., housing styles, living environments, and decorations) portrayed in Grades K-5 books exhibited lower authenticity (ranging from 43% to 54%), with notable enhancement in Grade 6 textbooks (98%) because Grade 6 books include China-related contexts across all units. Overall, the cultural authenticity increased from Grades K (82%) to 6 books (98%).
Feedback from the teacher survey highlighted the importance of the Mandarin Matrix program in facilitating Chinese reading and vocabulary acquisition among students. Teachers emphasized the need to increase cultural authenticity to promote students’ intercultural understanding. Although this research involved a limited number of participants with a narrow scope, it helps fill gaps in understanding how authentic Chinese language and culture are represented in elementary school materials. Evaluating the language and culture in the texts and pictures affords useful ideas for editors of Utah’s Chinese literacy curriculum. The overall results serve as valuable information for statewide professional development (PD). PD trainers can consider related insights to support Utah Chinese DLI teachers’ work to enrich students’ authentic language exposure and deepen their experiences with Chinese culture in the classroom.

description: The results of a submillimetre wavelength spectral line survey between 455.1 -- 507.4 GHz of the Orion-KL hot cloud core are reported. A total of 254 lines were detected to a main beam brightness temperature sensitivity ~ 1 - 3 K. The detected lines are identified as being associated with 30 different molecular species or their isotopomeric variants. The strongest line detected was the J = 4-3 transition of the CO molecule. Apart from abundant diatomic rotors such as CO and CS, the spectrum is dominated by SO, SO_2 and CH_3OH and large organic molecules such as (CH_3)_2O, CH$_3CN, C_2H_3CN, C_2H_5CN and HCOOCH_3 which make up ~ 72% of the total number of lines; unidentified lines ~ 13%; and other lines the remaining ~ 15% of the total. Rotational temperatures and column densities derived using standard rotation diagram analysis techniques were found to range from 70 - 300 K, and 10^14 - 10^17 cm^2 respectively.

description: We present results from an experiment designed to better understand the mechanism by which ocean currents and winds control flotsam drift. The experiment consisted in deploying in the Florida Current and subsequently satellite tracking specially designed drifting buoys of varied sizes, buoyancies, and shapes. We explain the differences in the trajectories described by the special drifters as a result of their inertia, primarily buoyancy, which constrains the ability of the drifters to adapt their velocities to instantaneous changes in the ocean current and wind that define the carrying flow field. Our explanation of the observed behavior follows from the application of a recently proposed Maxey--Riley theory for the motion of finite-size particles floating at the surface ocean. The nature of the carrying flow and the domain of validity of the theory are clarified, and a closure proposal is made to fully determine its parameters in terms of the carrying fluid system properties and inertial particle characteristics.

description: We show using covariant techniques that the Einstein static universe containing a perfect fluid is always neutrally stable against small inhomogeneous vector and tensor perturbations and neutrally stable against adiabatic scalar density inhomogeneities so long as c_{s}^2>1/5, and unstable otherwise. We also show that the stability is not significantly changed by the presence of a self-interacting scalar field source, but we find that spatially homogeneous Bianchi type IX modes destabilise an Einstein static universe. The implications of these results for the initial state of the universe and its pre-inflationary evolution are also discussed.

description: We present the results of a {\it Chandra} observation of the central region of Abell 3112. This cluster has a powerful radio source in the center and was believed to have a strong cooling flow. The X-ray image shows that the intracluster medium (ICM) is distributed smoothly on large scales, but has significant deviations from a simple concentric elliptical isophotal model near the center. Regions of excess emission appear to surround two lobe-like radio-emitting regions. This structure probably indicates that hot X-ray gas and radio lobes are interacting. From an analysis of the X-ray spectra in annuli, we found clear evidence for a temperature decrease and abundance increase toward the center. The X-ray spectrum of the central region is consistent with a single-temperature thermal plasma model. The contribution of X-ray emission from a multiphase cooling flow component with gas cooling to very low temperatures locally is limited to less than 10% of the total emission. However, the whole cluster spectrum indicates that the ICM is cooling significantly as a whole, but in only a limited temperature range ($\geq 2$ keV). Inside the cooling radius, the conduction timescales based on the Spitzer conductivity are shorter than the cooling timescales. We detect an X-ray point source in the cluster center which is coincident with the optical nucleus of the central cD galaxy and the core of the associated radio source. The X-ray spectrum of the central point source can be fit by a 1.3 keV thermal plasma and a power-law component whose photon index is 1.9. The thermal component is probably plasma associated with the cD galaxy. We attribute the power-law component to the central AGN.

Relation between positional specific heat and static relaxation length: Application to supercooled liquids

description: A general identification of the {\em positional specific heat} as the thermodynamic response function associated with the {\em static relaxation length} is proposed, and a phenomenological description for the thermal dependence of the static relaxation length in supercooled liquids is presented. Accordingly, through a phenomenological determination of positional specific heat of supercooled liquids, we arrive at the thermal variation of the static relaxation length $ξ$, which is found to vary in accordance with $ξ\sim (T-T_0)^{-ν}$ in the quasi-equilibrium supercooled temperature regime, where $T_0$ is the Vogel-Fulcher temperature and exponent $ν$ equals unity. This result to a certain degree agrees with that obtained from mean field theory of random-first-order transition, which suggests a power law temperature variation for $ξ$ with an apparent divergence at $T_0$. However, the phenomenological exponent $ν= 1$, is higher than the corresponding mean field estimate (becoming exact in infinite dimensions), and in perfect agreement with the relaxation length exponent as obtained from the numerical simulations of the same models of structural glass in three spatial dimensions.

description: Genus Euchonicola gen. nov.
Diagnosis. Adult female body highly transformed, comprising large ectosoma connected via short stalk to small flattened, discoid endosoma located within host. Ectosoma indistinctly segmented, comprising fused cephalothorax and trunk plus small abdomen. Abdomen distinct, unsegmented, bearing median anal slit terminally and paired caudal rami. Cement glands paired, conspicuous in posterior part of trunk of mature females. Egg sacs uniseriate. Endosoma flattened, irregularly discoid, typically elliptical and narrower than width of trunk. Ectosoma with 2 pairs of appendages close to base of stalk. Antennules reduced to unarmed lobes. Antennae 2-segmented, subchelate, comprising robust basal segment and curved apical claw. Other mouthparts and swimming legs all lacking. Male unknown.
Type species: Euchonicola caudatus gen. et sp. nov., by original designation.
Etymology. The name of the new genus is based on a combination of Euchone, the name of the host genus of the type species, and –icola meaning inhabitant: gender masculine.
Remarks. The organization of the body of the new genus is similar to that of saccopsids, with the entire body (cephalothorax, trunk, and small abdomen) forming an indistinctly segmented and undifferentiated ectosoma attached via a short stalk originating ventrally in the oral area which connects to a small flattened endosoma that lies within the host. The oral origin of the stalk is indicated by the positioning of the vestigial antennules and subchelate antennae around the base of the stalk. In some specimens the body appears to exhibit traces of serial subdivision along the longitudinal axis of the trunk region, however, the grooves between these apparent segments coincide with, and probably express, the spacing of the large eggs contained within the oviduct.
The new genus differs from Melinnacheres, Trichobranchicola gen. nov., and Lanassicola gen. nov. in the structure of the antennae and the lack of maxillae in the adult female. In all three of these saccopsine genera the antennae carry paired adhesion pads distally, whereas in Euchonicola gen. nov. the antennae are subchelate, terminating in a curved claw. The saccopsine genera are also characterized by the possession of well developed maxillae bearing paired adhesion pads distally, whereas in Euchonicola gen. nov. the maxillae are lacking.

description: In the inner regions of an accretion disk around a black hole, the presence of non-thermal protons would via p-p collisions produce electrons, positrons and $γ$-rays. For such a scenario, the steady state electron-positron distribution is computed taking into account Compton cooling, $e^{-} e^{+}$ pair production (due to $γ-γ$ interactions) and pair annihilation. The resultant spectra has a broad feature around $1 - 10$ MeV which may be tested with observations by INTEGRAL and GLAST. Using the available OSSE data for the black hole system, GRS 1915+115 we illustrate that an upper limit on the non-thermal proton fraction can be obtained, which may put constraints on the acceleration process active in this system.

description: Cosmic rays, along with stellar radiation and magnetic fields, are known to make up a significant fraction of the energy density of galaxies such as the Milky Way. When cosmic rays interact in the interstellar medium, they produce gamma-ray emission which provides an important indication of how the cosmic rays propagate. Gamma rays from the Andromeda Galaxy (M31), located 785 kpc away, provide a unique opportunity to study cosmic-ray acceleration and diffusion in a galaxy with a structure and evolution very similar to the Milky Way. Using 33 months of data from the High Altitude Water Cherenkov Observatory, we search for TeV gamma rays from the galactic plane of M31. We also investigate past and present evidence of galactic activity in M31 by searching for Fermi Bubble-like structures above and below the galactic nucleus. No significant gamma-ray emission is observed, so we use the null result to compute upper limits on the energy density of cosmic rays $>10$ TeV in M31. The computed upper limits are approximately ten times higher than expected from the extrapolation of the Fermi LAT results.

Type material: Holotype ♀ from Chone sp., Fish 2010, Stn 2-5 (71.79853°N, 21.16865°E), depth 320 m, 23 May 2010; collected by A. Sikorski; NHMUK Reg. No. 2015.3009. Paratype ♀ from Chone sp., FFH 3958, Stn B 3A (65.92825°N, 12.25177°E), depth 105 m, 23 March 2007; collected by A. Sikorski; NHMUK Reg. No. 2015.3010.
Differential diagnosis. Adult female attached to host via short oral stalk connecting ectosoma with discoid, embedded endosoma (Fig. 23A). Total length of cylindrical ectosoma 465 to 530 µm, with trunk about 2 times longer than wide (390 µm by 190 µm, respectively); retaining apparent traces of subdivision along body in some specimens (Fig. 23C), and with distinct abdomen (Fig. 23B). Stalk located anteriorly on ectosoma, with paired antennules and subchelate antennae positioned close to base of stalk. Antennules lobate, unarmed. Antennae comprising broad basal segment with swollen inner margin, and strongly recurved, claw-like apical subchela: tip of subchela opposing rounded swelling on myxal margin of basal segment when adducted. Ectosoma bearing paired, unarmed, rounded genital lappets posteriorly, marking genital openings (Fig. 23C). Paired cement glands visible posteriorly in trunk (Fig. 23A, C), extending over half length of trunk. Abdomen distinct, unsegmented, about 2 times longer than wide; bearing posteriorly-directed caudal rami and with median anal slit (Fig. 23B). Caudal rami parallel; each ramus with slight proximal swelling and narrower distal part; rami unarmed. Egg sacs unknown.
Etymology. The name of the new species refers to the posterior orientation of the caudal rami, which are held parallel with the longitudinal axis of the body.
Remarks. This species is very similar to the type species E. caudatus gen. et sp. nov. but can be distinguished by its relatively large ectosoma, 465 to 530 µm in length, compared to 406 to 443 µm in E. caudatus gen. et sp. nov. The form of the caudal rami also differs: in E. linearis gen. et sp. nov. the rami have a slight proximal swelling and are directed posteriorly whereas in E. caudatus gen. et sp. nov. they are markedly bipartite and directed laterally. The validity of these characters as specific level discriminants should be tested as more material becomes available.
This species is only known from females found on unidentified specimens of the sabellid genus Chone Krøyer, 1856, collected at depths of 105 to 320 m off the coast of northern Norway.

description: Light curves from a growing number of Gamma Ray Bursts (GRBs) indicate that GRBs copiously produce radioactive Ni moving outward at fractions of the speed of light. We calculate nuclear abundances of elements accompanying the outflowing Ni under the assumption that this Ni originates from a wind blown off of a viscous accretion disk. We also show that GRB's likely contribute appreciably to the galactic inventory of 42Ca, 45Sc, 46Ti, 49Ti, 63Cu, and may be a principal site for the production of 64Zn.

description: Understanding native point defects is fundamental in order to comprehend the properties of TiO$_2$ anatase in technological applications. Several first-principles studies have been performed in order to investigate the defect chemistry of this material. The reported values are, however, scattered over a wide range. In this manuscript we perform a comparative study employing different approaches based on semilocal, DFT+$U$ and screened hybrid functionals in order to investigate the dependence of defect properties, such as formation energies and charge transition levels, on the employed computational method. While the defects in anatase, like in most transition-metal oxides, generally induce the localization of electrons or holes on atomic sites, we notice that, provided an alignment of the valence bands has been performed, the calculated defect formation energies and transition levels using semi-local functionals are in a fair agreement with those obtained using hybrid functionals. A similar conclusion can be reached for the thermochemistry of the Ti-O system and the limit values of the elemental chemical potentials. We interpret this as a cancellation of error between the self-interaction error and the overbinding of the O$_2$ molecule in semi-local functionals. Inclusion of a $U$ term in the electron Hamiltonian offers a convenient way for obtaining more precise geometric and electronic configurations of the defective systems.
Quantum and thermal effects in the double exchange ferromagnet

description: The physics of the ferromagnetic phase of the ``double exchange'' model has been widely discussed in the context of the CMR manganites. Usually, the double exchange ferromagnet is treated is classically, by mapping it onto an effective Heisenberg model. However this mapping does not permit a correct treatment of quantum or thermal fluctuation effects, and the results obtained lack many of the interesting features seen in experiments on the manganites. Here we outline a new analytic approach to systematically evaluating quantum and thermal corrections to the magnetic and electronic properties of the double exchange ferromagnet.

description: Randomized controlled trials remain a gold standard in evaluating the efficacy and safety of a new treatment. Ideally, patients adhere to their treatments for the duration of the study, and the resulting data can be analyzed unambiguously for efficacy and safety outcomes. However, some patients may discontinue the study treatment due to intercurrent events, which leaves missing observations or observations that do not reflect the randomly assigned treatment. Frequently, an intent-to-treat analysis (or a modification thereof) is done to estimate the treatment effect for all randomized patients regardless of the occurrence of intercurrent events. Alternatively, clinicians may be more interested in understanding the efficacy and safety for those who can adhere to the study treatment. The naive per-protocol analysis may provide a biased estimate for the treatment difference because the observed adherence populations may not be comparable between two treatments. In this article, we propose two methods for estimation of the treatment difference for those who can adhere to one or both treatments based on the counterfactual framework. Theoretical derivations and a simulation study show the proposed methods provide consistent estimators for the treatment difference for the adherent population of interest. A real data example comparing two basal insulins for patients with type-1 diabetes is provided using the proposed methods. Supplementary materials for this article are available online.
Time Evolution of a Quantum Particle and a Generalized Uncertainty Principle

description: Some of the possible consequences of a generalized uncertainty principle (which emerges in the context of string theory and quantum gravity models as a consequence of fluctuations of the background metric) are analyzed considering the case of a quantum particle immersed in a homogeneous gravitational field. It will be shown that the expectation value of the momentum operator depends in a novel way on the mass of the involved particle. This kind of physical characteristics could be, in principle, detected. In other words, one way of confronting against the experiment some of the models around quantum gravity is given by the detection of the dependence upon the mass parameter of the expectation value of the momentum operator.

Social and Political Thought In The Early Narrative Of Rómula Gallegos
Creators: name: Allen, R.F.
Publisher: name: Digital Repository at the University of Maryland
Year: 1961

description: This dissertation is a study of the essays and short stories written by Rómulo Gallegos in the early years of the twentieth century. It traces his social and political ideas which were set forth in his essays and transferred into the early narrative work of the author. The essays and short stories, presented chronologically according to their date of publication, represent his successive works. Gallegos' ideas derive from the corruption of his native Venezuela ruled by anarchy and dictatorship. Born in Caracas in 1884 under the dictatorial regime of Cipriano Castro, Gallegos first attracted a reading public in 1906 with his collection of essays published originally in the literary journal La Alborada. The essays, from the obscure files of this long dead periodical, constitute the symposium entitled Una posición en la vida, 1954. Showing the influence of nineteenth century European and Latin-American positivism, these essays set forth his fundamental social and political beliefs and reforms . Another dictator, Juan Vicente Gómez, put an end to this literary activity by closing the review. Gallegos then made his debut as a short story writer, publishing more than thirty stories in the literary periodicals entitled El Cojo Ilustrado, La Revista, Actualidades, and La Novela Semanal. In these stories, the patriotic preoccupations of the essays come to life. Eventually Gallegos became a novelist, establishing himself as a major writer of Spanish-American fiction. He is noted for his intention to effect reform and for his interest in the traditions and the national soul of the Venezuelan people. This dissertation shows the trends started in the essays, applied to the short stories, and developed to a larger scope in the novel.

description: The recent discovery of H3S and LaH10 superconductors with record high superconducting transition temperatures, Tc, at high pressure, has fueled the search for room-temperature superconductivity in the compressed superhydrides. Here we predict the existence of an unprecedented hexagonal HfH10, with an extraordinarily high Tc of around 213-234 K at 250 GPa. In HfH10, the H atoms are arranged in clusters to form a planar "penta-graphene-like" sublattice, in contrast to the covalent sixfold cubic structure in H3S and clathrate-like structure in LaH10. The Hf atom acts as a "precompressor" and electron donor to the hydrogen sublattice. This "penta-graphene-like" H10 structure is also found in ZrH10, ScH10 and LuH10 at high pressure, each material showing a high Tc ranging from 134 to 220 kelvin. Our study of dense superhydrides with "penta-graphene-like" layered structures opens the door to the exploration and exploitation of a new class of high Tc superconductors.

description: At very high energies the Earth magnetic field, although in many other connections conside red rather weak, acts as a strong field on photons and leptons. This paper discusses the i ntimate connection between this effect and the corresponding `strong field effects' observ ed at accessible accelerator energies in aligned single crystals. As such, these effects c onstitute an experimental verification of the theoretical basis used for simulations of th e development of electromagnetic showers in magnetic fields, in particular the geomagnetic field. A short discussion of more general aspects of the shower development in the fields present at different distance scales is included.

The Attitudes of Volunteer Leaders in Cecil, Harford and Kent Counties, Maryland Toward Involvement of Handicapped in 4-H Programs
Creators: name: Coleman, Bernardine Marie

Year: 1982

description: The purpose of this exploratory study was to determine if volunteer 4-H leaders in Cecil, Harford, and Kent Counties in Maryland were receptive towards involvement of handicapped youth in 4-H programs and if training was needed prior to program implementation. Seventy-four volunteer leaders in the three counties surveyed returned completed mail questionnaires. An attitude rating scale was used to assess leaders attitudes toward involvement of handicapped youth in 4-H programs. Demographic and personal data were requested in Part II of the survey instrument. Frequency distribution and the chi-square test were used to analyze data. Level of significance was set at .05. The majority of leaders had positive feelings about the involvement of handicapped youth in 4-H programs but felt training was needed before involvement took place. Significant relationships were found between age and the attitudes concerning, l) involvement of handicapped youth as being a good experience for other 4-H members, 2) handicapped youth being able to participate adequately in 4-H programs, 3) 4-H being a help to mentally retarded youth and, 4) the belief that other groups were meeting the needs of handicapped youth. Significant relationships were also found between education and the attitude concerning, l) involvement of handicapped youth as being a good experience for handicapped youth, 2) feeling comfortable with emotionally handicapped, educable and trainable mentally retarded children and, 3) having adequate training to work with handicapped youth.
