description: Standardized tests play a central role in nearly all modern schools in the United States. Recent research has indicated that many of these standardized tests do not effectively measure students' underlying knowledge of a subject. Additional research must be completed to find innovative and effective items that have not only successfully measure student ability, but also provide educators with information about those abilities so they can effectively address student deficiencies. 371 participants were recruited from introductory statistics courses and given an assessment that contained both traditional single-response multiple choice items and multiple-select multiple-choice items. The participants were also randomly divided into two conditions, one where the directions told them they should select single responses for the single-response items and multiple responses for the multi-select items. The second condition instructed participants that all items could have multiple responses. All items were analyzed using traditional IRT and Bayesian IRT methods. Items analyzed with Bayesian methods have yielded significant statistical differences in item difficulty parameters versus traditional 1-PL Item Response Theory models, especially for items that had high difficulty parameter values. Further validation of the participants results was done with Bayesian regression models, which indicated that there was a moderately weak relationship between student performance on standard in-class examinations versus results on the instrument used in this study, which indicates that participant performance is not strongly related to performance on in-class exams. This indicates that further analysis of multiple-select items is warranted. Additionally, since multiple-select items are multifaceted, they have the potential to provide instructors with the ability to see if a student has full, partial, or no understanding of a concept as opposed to traditional single response multiple-choice items
Microscopic description of the beta delayed deuteron emission from \bbox{^6}He

description: The beta delayed deuteron emission from $^6$He is studied in a dynamical microscopic cluster model. This model gives a reasonably good description for all the subsystems of $^6$He and $^6$Li in a coherent way, without any free parameter. The beta decay transition probability to the $^6$Li ground state is underestimated by a few percents. The theoretical beta delayed deuteron spectrum is close to experiment but it is also underestimated by about a factor 1.7. We argue that, in spite of their different magnitudes, both underestimations might have a common origin. The model confirms that the neutron halo part of the $^6$He wave function plays a crucial role in quenching the beta decay toward the $α$ + d channel.

description: This work presents a study of galactic outflows driven by stellar feedback. We extract main sequence disc galaxies with stellar mass $10^9\le$ M$_{\star}/$M$_{\odot} \le 5.7\times10^{10}$ at redshift $z=0$ from the highest resolution cosmological simulation of the Evolution and Assembly of GaLaxies and their Environments (EAGLE) set. Synthetic gas rotation velocity and velocity dispersion ($σ$) maps are created and compared to observations of disc galaxies obtained with the Sydney-AAO Multi-object Integral field spectrograph (SAMI), where $σ$-values greater than $150$ km s$^{-1}$ are most naturally explained by bipolar outflows powered by starburst activity. We find that the extension of the simulated edge-on (pixelated) velocity dispersion probability distribution depends on stellar mass and star formation rate surface density ($Σ_{\rm SFR}$), with low-M$_{\star}/$low-$Σ_{\rm SFR}$ galaxies showing a narrow peak at low $σ$ ($\sim30$ km s$^{-1}$) and more active, high-M$_{\star}/$high-$Σ_{\rm SFR}$ galaxies reaching $σ>150$ km s$^{-1}$. Although supernova-driven galactic winds in the EAGLE simulations may not entrain enough gas with T $<10^5$ K compared to observed galaxies, we find that gas temperature is a good proxy for the presence of outflows. There is a direct correlation between the thermal state of the gas and its state of motion as described by the $σ$-distribution. The following equivalence relations hold in EAGLE: $i)$ low-$σ$ peak $\,\Leftrightarrow\,$ disc of the galaxy $\,\Leftrightarrow\,$ gas with T $<10^5$ K; $ii)$ high-$σ$ tail $\,\Leftrightarrow\,$ galactic winds $\,\Leftrightarrow\,$ gas with T $\ge 10^5$ K.

description: The standard expression of the high-temperature Casimir force between perfect conductors is obtained by imposing macroscopic boundary conditions on the electromagnetic field at metallic interfaces. This force is twice larger than that computed in microscopic classical models allowing for charge fluctuations inside the conductors. We present a direct computation of the force between two quantum plasma slabs in the framework of non relativistic quantum electrodynamics including quantum and thermal fluctuations of both matter and field. In the semi-classical regime, the asymptotic force at large slab separation is identical to that found in the above purely classical models, which is therefore the right result. We conclude that when calculating the Casimir force at non-zero temperature, fluctuations inside the conductors can not be ignored.

title: Analysis of Central Equatorial Pacific Water Masses by Method of Principal Components

Publisher: name: Old Dominion University

publisherIdentifierScheme: ROR
Year: 1984

description:
The distribution of Antarctic Intermediate Water at the extent of dispersion in the equatorial Pacific Ocean was investigated by means of multivariate analysis. Interrelationships among the upper intermediate water masses at this location are proposed.

Oceanographic data contained in seven cruise legs measured during the 1979-80 Hawaii to Tahiti Shuttle Experiment formed the basis of this study. Six parameters -- temperature, salinity, dissolved oxygen, phosphate, silicate and nitrate -- were used in the method of principal component analysis to classify water masses between the sea surface and 1000m. The derived water masses were compatible with previously described oceanographic features of the region. Validity of the classification was measured by Discriminant Analysis and was found to be significant.

Two salinity minimum layers were determined. A deep layer (800-1000m) corresponded to core and upper AAIW, while the shallow layer was low salinity water from both the North and South Pacific. AAIW and shallow low salinity water from the South Pacific were maintained as nearly continuous spatial and temporal features of the water structure. Low salinity water in the shallow layer from the North Pacific exhibited seasonal fluctuation in extent of intrusion and thickness. Its influence appeared to be superimposed onto that of the South Pacific shallow minimum. It is proposed that this water mass is composed of water from two sources -- subarctic Pacific and East North Pacific (via the California Current).

AAIW was found to spread into the North Pacific to 2°N-4°N as a near pure core, but beyond that extent was altered through mixing with higher salinity water above and North Pacific intermediate waters. Traces of AAIW were discernible as far north as 11°N.

description: Quantum cryptography is set to become a key technology for future secure communications. However, to get maximum benefit in communication networks, transmission links will need to be shared among several quantum keys for several independent users. Such links will enable switching in quantum network nodes of the quantum keys to their respective destinations. In this paper we present an experimental demonstration of a photonic integrated silicon chip quantum key distribution protocols based on space division multiplexing (SDM), through multicore fiber technology. Parallel and independent quantum keys are obtained, which are useful in crypto-systems and future quantum network.

description: Abstract: "Microstructural properties of materials, especially crystalline solids, are implicated in many of their properties. Vice versa, there are macroscopic environments which limit microstructural configurations. Certain iron/rare earth alloys, eg, TbDyFeΓéé, display both a huge magnetostriction and frustration, i.e., minimum energy not achieved, in which microstructure plays an important, if puzzling, role. We discuss this example in the framework of continuum thermoelasticity theory, where symmetry demands energy densities which are highly degenerate. This leads to novel analytical and computational issues, many of which we have been unable to resolve."

description: We compute radiative corrections in five and six dimensional field theories, using winding modes in mixed momentum-coordinate space. This method provides a simple way of finding UV divergencies, finite corrections and localized terms when the space is compactified on orbifolds. As an application we compute the finite piece of scalar masses, the logarithmic contributions to the couplings and the effect of localized parallel and perpendicular kinetic terms. We apply it to get a two loop effective potential that can stabilize large extra dimensions.

Areal geology of the Catahoula formation in Gonzales and Karnes Counties, Texas, with notes on outcrops in adjacent counties

Subjects: subject: Geology--Texas--Karnes County

description: The Catahoula sandstone as mapped by Deussen has been traced southwestward from Fayette County, and observed to merge by gradual lithologic change into the essentially pyroclastic clays and tuffs of the lower portion of Dumble's Frio, which is the Fant member of Bailey's Gueydan. The Catahoula is overlain disconformably by the Oakville sandstone over part of its outcrop as mapped in this paper, and overlain disconformably by what is probably the southwest Texas equivalent of the Fleming clay of east Texas. It overlies the strata of Jackson and Vicksburg age with a very marked unconformity, most noticeable in Gonzales County, where the contact is marked by a coarse conglomerate. Structural relief presented by the unconformity between the Catahoula and lower beds amounts to two hundred feet between Gonzales County and the Frio River, along the outcrop of the formation. The formation varies in width from one mile in Gonzales County to three miles in Live Oak County, and the rate of dip ranges from one hundred feet per mile in the latter county to one hundred and twenty-five feet per mile in the former.
Presupernova Evolution of Rotating Massive Stars II: -- Evolution of the Surface Properties

Year: 2000

description: We investigate the evolution of the surface properties of models for rotating massive stars, i.e., their luminosities, effective temperatures, surface rotational velocities, and surface abundances of all isotopes, from the zero age main sequence to the supernova stage. Our results are based on the grid of stellar models by Heger, Langer, & Woosley, which covers solar metallicity stars in the initial mass range 8 - 25 solar masses. Results are parameterized by initial mass, initial rotational velocity and major uncertainties in the treatment of the rotational mixing inside massive stars. Rotationally induced mixing processes widen the main sequence and increase the core hydrogen burning lifetime, similar to the effects of convective overshooting. It can also significantly increase the luminosity during and after core hydrogen burning, and strongly affects the evolution of the effective temperature. Our models predict surface rotational velocities for various evolutionary stages, in particular for blue supergiants, red supergiants, and for the immediate presupernova stage. We discuss the changes of the surface abundances due to rotationally induced mixing for main sequence and post main sequence stars. We single out two characteristics by which the effect of rotational mixing can be distinguished from that of massive close binary mass transfer, the only alternative process leading to non-standard chemical surface abundances in massive stars. A comparison with observed abundance anomalies in various types of massive stars supports the concept of rotational mixing in massive stars and indicates that it is responsible for most of the observed abundance anomalies.

description: Understanding the hydrologic connectivity between kettle holes and shallow groundwater, particularly in reaction to the highly variable local meteorological conditions, is of paramount importance for tracing water in a hydro(geo)logically complex landscape and thus for integrated water resource management. This article is aimed at identifying the dominant hydrological processes affecting the kettle holes' water balance and their interactions with the shallow groundwater domain in the Uckermark region, located in the north-east of Germany. For this reason, based on the stable isotopes of oxygen (delta O-18) and hydrogen (delta H-2), an isotopic mass balance model was employed to compute the evaporative loss of water from the kettle holes from February to August 2017. Results demonstrated that shallow groundwater inflow may play the pivotal role in the processes taking part in the hydrology of the kettle holes in the Uckermark region. Based on the calculated evaporation/inflow (E/I) ratios, most of the kettle holes (86.7%) were ascertained to have a partially open, flow-through-dominated system. Moreover, we identified an inverse correlation between E/I ratios and the altitudes of the kettle holes. The same holds for electrical conductivity (EC) and the altitudes of the kettle holes. In accordance with the findings obtained from this study, a conceptual model explaining the interaction between the shallow groundwater and the kettle holes of Uckermark was developed. The model exhibited that across the highest altitudes, the recharge kettle holes are dominant, where a lower ratio of E/I and a lower EC was detected. By contrast, the lowest topographical depressions represent the discharge kettle holes, where a higher ratio of E/I and EC could be identified. The kettle holes existing in between were categorized as flow-through kettle holes through which the recharge takes place from one side and discharge from the other side.

description: We investigate the nature of the extragalactic unresolved gamma-ray background (UGRB) by cross-correlating several galaxy catalogs with sky-maps of the UGRB built from 78 months of Pass 8 Fermi-Large Area Telescope data. This study updates and improves similar previous analyses in several aspects. Firstly, the use of a larger gamma-ray dataset allows us to investigate the energy dependence of the cross-correlation in more detail, using up to 8 energy bins over a wide energy range of [0.25-500] GeV. Secondly, we consider larger and deeper catalogs (2MASS Photometric-Redshift catalog, 2MPZ; WISE x SuperCOSMOS, WISC; and SDSS-DR12 photometric-redshift dataset) in addition to the ones employed in the previous studies (NVSS and SDSS-QSOs). Thirdly, we exploit the redshift information available for the above catalogs to divide them into redshift bins and perform the cross-correlation separately in each of them. Our results confirm, with higher statistical significance, the detection of cross-correlation signal between the UGRB maps and all the catalogs considered, on angular scales smaller than 1 degree. Significances range from 16.3 sigma for NVSS, 7 sigma for SDSS-DR12 and WISC, 5 sigma for 2MPZ and 4 sigma for SDSS-QSOs. Furthermore, including redshift tomography, the significance of the SDSS-DR12 signal strikingly rises up to 12 sigma and the one of WISC to 10.6 sigma. We offer a simple interpretation of the signal in the framework of the halo model. The precise redshift and energy information allows us to clearly detect a change over redshift in the spectral and clustering behavior of the gamma-ray sources contributing to the UGRB.

Resonant x-ray scattering at the LIII absorption edge of Dy was utilized. Analysis of the energy, polarization, temperature, and azimuthal-angle dependences of the E1 resonance of the (1 0 0) forbidden reflection show that the magnetic and quadrupolar components within the frustrated c plane have a short-range correlation, suggesting that the moments are fluctuating. By contrast, the basic antiferromagnetic component along the c axis has a long-range order.

description: We consider an elliptic eigenvalue problem with a fast cellular flow of amplitude A , in a two-dimensional domain with L2 cells. For fixed A , and L→∞, the problem homogenizes, and has been well studied. Also well studied is the limit when L is fixed, and A→∞. In this case the solution equilibrates along stream lines. In this paper, we show that if both A→∞ and L→∞, then a transition between the homogenization and averaging regimes occurs at A≈L4. When A≫L4, the principal Dirichlet eigenvalue is approximately constant. On the other hand, when A≪L4, the principal eigenvalue behaves like σ(A)/L2 , where σ(A) ≈ √ AI is the effective diffusion matrix. A similar transition is observed for the solution of the exit time problem. The proof in the homogenization regime involves bounds on the second correctors. Miraculously, if the slow profile is quadratic, these estimates can be obtained using drift independent Lp→L∞ estimates for elliptic equations with an incompressible drift. This provides effective sub- and super-solutions for our problem.

description: It was recently proven that, under mild restrictions, grad-div stabilized Taylor-Hood solutions of Navier-Stokes problems converge to the Scott-Vogelius solution of that same problem. However, even though the analytical rate was only shown to be $gamma^-frac12$ (where $gamma$ is the stabilization parameter), the computational results suggest the rate may be improvable $gamma^-1$. We prove herein the analytical rate is indeed $gamma^-1$, and extend the result to other incompressible flow problems including Leray-$alpha$ and MHD. Numerical results are given that verify the theory.

description: For a smooth near identity map, we introduce the notion of an interpolating vector field written in terms of iterates of the map. Our construction is based on Lagrangian interpolation and provides an explicit expressions for autonomous vector fields which approximately interpolate the map. We study properties of the interpolating vector fields and explore their applications to the study of dynamics. In particular, we construct adiabatic invariants for symplectic near identity maps. We also introduce the notion of a Poincaré section for a near identity map and use it to visualise dynamics of four dimensional maps. We illustrate our theory with several examples, including the Chirikov standard map and a symplectic map in dimension four, an example motivated by the theory of Arnold diffusion.

description: The biogeochemistry of continental shelf systems is an important, but poorly quantified, component of the global cycling of nitrogen and carbon. In this study, simulations obtained from a one-dimensional (ID) biogeochemical model developed for the Middle Atlantic Bight (MAB) portion of the U.S. eastern continental shelf were analyzed to investigate nitrogen cycling processes. The 1D model included lower trophic level interactions and was forced by advective fields obtained from a corresponding three-dimensional biogeochemical model. Taylor and target diagram analyses, which compared in situ measurements of sea surface temperature (SST) and salinity, and chlorophyll and particulate organic carbon (POC) derived from Sea-Wide-Field-of-Viewing (Sea WiFS) observations with equivalent distributions obtained from the model simulations, were used to select sub-regions of the MAB for detailed analysis of lower trophic level interactions and nitrogen cycling with the 1D model. Higher correlation coefficients and relatively lower unbiased root-mean-square values were obtained for the SST (R > 0.97) and salinity (R > 0.97), while correspondence between Sea WiFS-derived chlorophyll and POC and the corresponding simulated distributions were less robust. The 1D model simulations showed regional variability in the skill of modeled depth-integrated primary production (~300 g C m-2 yr-1) and mean euphotic zone chlorophyll. Low primary production and chlorophyll concentrations during summer in some of the MAB sub regions resulted from reduced light availability and stronger stratification. Regional nitrogen budgets constructed from the simulated distributions showed that regenerated production, small detritus remineralization, nitrification, and zooplankton assimilation were lower in these regions by a factor of 1.5 compared with other sub-regions. The sensitivity of the simulations to 25% variations in the value of selected parameters was also tested. These analyses provided insights into adjustments for the rates and parameterizations used to simulate phytoplankton processes, and helped to identify and understand the important biogeochemical processes controlling nitrogen cycling in the MAB continental shelf waters.

description: We study a diffusion model of phase field type, consisting of a system of two partial differential equations encoding the balances of microforces and microenergy; the two unknowns are the order parameter and the chemical potential. By a careful development of uniform estimates and the deduction of certain useful boundedness properties, we prove existence and uniqueness of a global-in-time smooth solution to the associated initial/boundary-value problem; moreover, we give a description of the relative $omega$-limit set.

Electromagnetic Currents and the Blankenbecler-Sugar Equation
Creators: name: Coester, F.

Year: 1993
Subjects: subject: Nuclear Theory (nucl-th)

description: The effective electromagnetic current density for a two-nucleon system that is described by the Blankenbecler-Sugar equation is derived. In addition to the single nucleon currents there are exchange currents of two different origins. The first is the exchange current that is required to compensate for the violation of the continuity equation in the impulse approximation. The second is an exchange current, which arises in the quasipotential reduction from the Bethe-Salpeter equation, and which represents effects of suppressed degrees of freedom. Explicit general expressions are given for both of these exchange currents. The results are applicable to both elastic and inelastic processes.

description: In this paper we study optimal control problems governed by semilinear parabolic equations where the spatial dimension is two or three. Moreover, we consider pointwise constraints on the control and on the state. We formulate first order necessary and second order sufficient optimality conditions. We make use of recent results regarding elliptic regularity and apply the concept of maximal parabolic regularity to the occurring partial differential equations.

description: We consider systems of reaction-diffusion equations as gradient systems with respect to an entropy functional and a dissipation metric given in terms of a so-called Onsager operator, which is a sum of a diffusion part of Wasserstein type and a reaction part. We provide methods for establishing geodesic lambda-convexity of the entropy functional by purely differential methods, thus circumventing arguments from mass transportation. Finally, several examples, including a drift-diffusion system, provide a survey on the applicability of the theory.

description: Abstract: "We establish a new and intriguing connection between the Fokker-Planck equation with gradient drift term and an associated free energy functional. Namely, we demonstrate that such a Fokker-Planck equation may be interpreted as a gradient flux, or a steepest descent, of a free energy functional with respect to a certain metric. This is accomplished through the construction of a time-discrete iterative variational scheme whose solutions converge to the solution of the Fokker-Planck equation. The time step in this scheme is governed by the Wasserstein metric on probability measures."

description: We discuss possible extensions of the recently established theory of evolutionary Gamma convergence for gradient systems to nonlinear dynamical systems obtained by perturbation of a gradient systems. Thus, it is possible to derive effective equations for pattern forming systems with multiple scales. Our applications include homogenization of reaction-diffusion systems, the justification of amplitude equations for Turing instabilities, and the limit from pure diffusion to reaction-diffusion. This is achieved by generalizing the Gamma-limit approaches based on the energy-dissipation principle or the evolutionary variational estimate.

description: We report the structural and magnetoelectrical properties of La$_{0.7}$Ca$_{0.3}$MnO$_3$/BaTiO$_3$ perovskite superlattices grown on (001)-oriented SrTiO$_3$ by the pulsed laser deposition technique. Magnetic hysteresis loops together with temperature dependent magnetic properties exhibit well-defined coercivity and magnetic transition temperature (T$_C$) \symbol{126}140 K. $DC$ electrical studies of films show that the magnetoresistance (MR) is dependent on the BaTiO$_3$ thickness and negative $MR$ as high as 30% at 100K are observed. The $AC$ electrical studies reveal that the impedance and capacitance in these films vary with the applied magnetic field due to the magnetoelectrical coupling in these structures - a key feature of multiferroics. A negative magnetocapacitance value in the film as high as 3% per tesla at 1kHz and 100K is demonstrated, opening the route for designing novel functional materials.

The Darst Creek oil field, Guadalupe County, Texas
Creators: name: McCallum, Henry De Rosset
Publisher: name: The University of Texas at Austin
Year: 1932
Subjects: subject: Petroleum--Texas--Guadalupe County

description: The Darst Green Oil Field, the fourth Edwards limestone field in southwest Texas, was discovered July 18, 1929, in eastern Guadalupe County (fig. 1). It is located along one of a series of "en échelon" faults parallel with, and southeast of, the fault zone of Texas. After migrating up-dip from the southeast, the oil in this field was trapped in the upper 50 feet of the porous Edwards limestone, which was faulted into juxtaposition with the impervious beds on the downthrown side of the fault. In addition to wells producing from the Edwards, several produce from fault plane cavities, and two supposedly are producing from reworked serpentine deposits. The maximum vertical displacement along the fault is calculated to be approximately 550 feet on top of the Austin chain. The surface beds in the area are middle and upper Indio sandy clays of lower Eocene age. Aside from fault planes, the structure is evidenced on the surface by steep dips, a decided down-dip swing in the Indio-Carrizo contact, and a repetition of upper Indio. The productive area of the field, including the Appling area to the northeast, consists of approximately 1670 acres. It is 6 miles in length and in places exceeds 4000 feet in width. Of the 291 wells drilled in the area, only 19 are dry holes. The total production through December 1931, was 19,700,340 barrels. The oil has a paraffin base, a deep green color, and a specific gravity of 36° Baumé. As proration has been in effect since the field was discovered, the development has been very slow. This, however, has proved beneficial by delaying the encroachment of sulphur water and tending to increase the ultimate recovery of oil.

description: There exists a variety of software tools for analyzing functional Magnetic Resonance Imaging data. A very popular one is the freely available SPM package by the Functional Imaging Laboratory at the Wellcome Department of Imaging Neuroscience. In order to enhance the signal-to-noise ratio it provides the possibility to smooth the data in a pre-processing step by a Gaussian filter. However, this comes at the cost of reducing the effective resolution. In a series of recent papers it has been shown, that using a structural adaptive smoothing algorithm based on the Propagation-Separation method allows for enhanced signal detection while preserving the shape and spatial extent of the activation areas. Here, we describe our implementation of this algorithm as a toolbox for SPM.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.
