description: Most schools in rural areas do not have teachers who are certified to teach computer science (CS), which prevents them from offering CS courses. Although reducing certification requirements may seem like an effective way to increase the number of teachers who can teach CS, our findings suggest that reducing CS certification requirements is unlikely to increase schools’ capacity to offer CS courses. We investigated how capacity to offer CS courses differs by school locale (e.g., rural versus urban) and how teacher certification requirements relate to whether schools offer CS courses. We found that less than a quarter of schools in rural areas have teachers certified to teach computer science (CS), compared to about half of schools in urban and suburban areas. Contrary to what might be expected, we also found that schools that do not require CS certification (i.e., charter schools) offer CS courses at lower rates than school that require CS certification (i.e., non-charter public schools). Policies beyond reducing CS certification requirements are needed to increase schools’ capacity to offer CS courses for students. For schools in rural areas that are especially in need of support to bring CS to their students, it is critical to expand professional learning in rural areas through virtual options that are more accessible to geographically dispersed teachers

description: In many fields of research and high-value industry, the estimation of distances and displacements is crucial. Due to their extremely high spatial resolution and flexible application possibilities interferometers are cross-sectorally used in measurement practice. However, classical length measuring interferometers are subject to two residual restrictions. On the one hand, only displacements that are exactly aligned to the interferometer optical axis can be measured. On the other hand, deviating refractive indices in the measuring and reference arm due to different atmospheric conditions represent an accuracy-limiting disturbance. In this paper, a new interferometric concept for length measurement is presented. The concept is based on the range-resolved interferometry technology which enables the simultaneous readout and evaluation of two symmetrical interferometric signals which result from the superposition of two non-collimated spherical wavefronts. This allows a point-to-point measurement between two optical fiber ends and the separation of undesired changes of the optical path length outside the measurement cavity and within the measurement cavity.

description: The University of Texas at Austin’s OnRamps program uses a dual enrollment model via distance learning to increase the number and diversity of students who are fully prepared to follow a path to college and career success. A prior study improved our understanding of the academic and demographic characteristics of OnRamps students. Given the tremendous growth of the OnRamps program, which enrolled almost 42,000 students last year in sixteen courses, this study focuses on longitudinal measures of college readiness and success. Using a high school fixed effect model and a model using inverse probability weighting with regression adjustment (IPWRA), we examine the impact of OnRamps participation and performance on a range of student outcomes. We find that participating in OnRamps and/or earning college credit through OnRamps leads to positive impacts on semester credits earned and the likelihood of earning a bachelor’s degree in four years. We also see that OnRamps tends to have the greatest benefit for underrepresented students.

description: Algorithms to determine transition probabilities in Monte Carlo simulations are tested using a system of classical particles with effective interactions which reproduce Bose-Einstein statistics. The system is appropriate for testing different Monte Carlo simulation methods in out-of-equilibrium situations since non equivalent results are produced. We compare mobility numerical results obtained with transition probabilities derived from Glauber and Metropolis algorithms. Then, we compare these with a recent method, the interpolation algorithm, appropriate for non-equilibrium systems in homogeneous substrata and without phase transitions. The results of mobility obtained from the interpolation algorithm are qualitatively verified with molecular dynamics simulations for low concentrations.

description: We rigorously derive from first principles the generic Landau amplitude equation that describes the primary bifurcation in electrically driven convection. Our model accurately represents the experimental system: a weakly conducting, submicron thick liquid crystal film suspended between concentric circular electrodes and driven by an applied voltage between its inner and outer edges. We explicitly calculate the coefficient $g$ of the leading cubic nonlinearity and systematically study its dependence on the system's geometrical and material parameters. The radius ratio $α$ quantifies the film's geometry while a dimensionless group ${\cal P}$, similar to the Prandtl number, fixes the ratio of the fluid's electrical and viscous relaxation times. Our calculations show that for fixed $α$, $g$ is a decreasing function of ${\cal P}$, as ${\cal P}$ becomes smaller, and is nearly constant for ${\cal P} \gtrsim 1$. As ${\cal P} \to 0$, $g \to \infty$. We find that $g$ is a nontrivial and discontinuous function of $α$. We show that the discontinuities occur at codimension-two points that are accessed by varying $α$.

description: The static configuration of ferroelectric domain walls was investigated using atomic force microscopy on epitaxial PbZr0.2Ti0.8O3 thin films. Measurements of domain wall roughness reveal a power law growth of the correlation function of relative displacements B(L) ~ L^(2zeta) with zeta ~ 0.26 at short length scales L, followed by an apparent saturation at large L. In the same films, the dynamic exponent mu was found to be ~ 0.6 from independent measurements of domain wall creep. These results give an effective domain wall dimensionality of d=2.5, in good agreement with theoretical calculations for a two-dimensional elastic interface in the presence of random-bond disorder and long range dipolar interactions.

description: This work presents a novel approach for improving interferometer resolution with a relatively simple setup by combining the use of range-resolved interferometry and a high-finesse Fabry-Perot setup utilizing multiple reflections in the cavity to gradually increase the resolution. This approach could enable the measurement of small displacements with a potentially much higher resolution than current interferometry methods. A simple proof-of concept setup demonstrated the evaluation of up to four Fabry-Perot passes, while theoretically much higher sensitivity improvement factors should be possible.

description: Following two seasons of excavations on a building to the south of the known Roman fort platform at Low Borrowbridge, Lunesdale Archaeology Society undertook a programme of non-intrusive investigation through topographical and geophysical surveys of the interior and immediate environs of the fort. The objective was to discover the state of preservation of internal structures, and to reveal the extent of any possible vicus remains outside the fort. Internally the footings of the central range of buildings are clear and demonstrate a layout similar to other, excavated forts of the late first and second century in the north of England. The surveys in the fields surrounding the fort platform failed to find evidence of a structured vicus, but did reveal a series of large rectangular ditched enclosures, which were subsequently excavated and dated to the first to second century, contemporaneous with the occupation of the fort.

description: A compact fiber laser interferometer, capable of precise displacement measurements, was devised using a 1550 nm DFB laser for frequency modulation up to 300 kHz. The system comprises a fiber laser, a fiber-optic interferometer, and a wavelength modulation system. The presented method offers nanometer-scale precision and incorporates a hydrogen cyanide (HCN) gas cell for monitoring the laser's central wavelength. A technique to compensate for modulation depth has been developed to maintain a consistent modulation depth over extensive measurement ranges. Preliminary trials reveal a measurement bias of less than 40 nm achieved over a 300 mm range at a speed of 100 mm/s compared to a calibrated interferometer. This approach proves beneficial for high-precision measurements for inline semiconductor manufacturing processes.

description: Planets and satellites orbiting a binary system exist in the solar system and extrasolar planetary systems. Their orbits can be significantly different from Keplerian orbits, if they are close to the binary and the secondary-to-primary mass ratio is high. A proper description of a circumbinary orbit is in terms of the free eccentricity $e_{\rm free}$ at the epicyclic frequency $κ_0$, forced eccentricity $e_{\rm forced}$ at the mean motion $n_0$, and oscillations at higher frequencies forced by the non-axisymmetric components of the binary's potential. We show that accurate numerical values for the amplitudes and frequencies of these terms can be extracted from numerical orbit integrations by applying fast Fourier transformation (FFT) to the cylindrical distance between the circumbinary object and the center of mass of the binary as a function of time. We apply this method to three Kepler circumbinary planets and the satellites of Pluto-Charon. For the satellite Styx of Pluto-Charon, the FFT results for $κ_0$ and $e_{\rm free}$ differ significantly from the first-order analytic value and the value reported by Showalter & Hamilton (2015), respectively. We show that the deviation in $κ_0$ is likely due to the effect of the 3:1 mean-motion resonance and discuss the implications of the lower value for $e_{\rm free}$.

description: This work is focused on the understanding of charging and discharging processes in silicon nanocrystal flash memories during program and erase operations through time-dependent numerical simulations. Time dependent simulations of the program and erase operations are based on a description of the nanocrystal memory dynamics in terms of a master equation. The related transition rates are computed with a one dimensional Poisson-Schroedinger solver which allows the computation of the tunnelling currents and of generation and recombination rates between the outer reservoir and localized states in the dielectric layer. Comparison between simulations and experiments available in the literature provides useful insights of the storing mechanisms. In particular, simulations allow us to rule out that electrons are stored in confined states in the conduction band of silicon nanocrystals, whereas they suggest that electrons are actually trapped in localized states in the silicon gap at an energy close to the silicon valence band edge, and located at the interface between the nanocrystals and the surrounding silicon oxide.

Stakeholders’ receptiveness to an ethnomathematics curriculum foundation : the case of Cameroon
Creators: name: Kang, Henry
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study is to assess the curriculum stakeholders' receptiveness to a curriculum built on an ethnomathematics foundation. The stakeholders who participated in this study were secondary school students, secondary mathematics teachers, pedagogic personnel and teacher educator. The students and the teachers were from two secondary schools in Cameroon, one of which was public and the other private. Data collected for analysis include audiotaped interview transcripts, questionnaires and field notes from classroom observations of the teaching of an ethnomathematics unit. From an analysis and interpretation of the data, a picture emerged of the stakeholders' level of interests and concern about adopting an ethnomathematics curriculum foundation. Findings from this study indicate that the stakeholders are generally receptive to an ethnomathematics curriculum but are also concerned about the demands such a curriculum would have on the cultural knowledge background of those in the mathematics classroom. The study also indicates that the stakeholders' encounter with an ethnomathematics approach can help them develop a broader view of mathematics and raise awareness of the presence of mathematical processes in cultural practices. The study notes that the stakeholders demonstrated both situational and actualized interests that were complex and not fixed. When a particular cultural activity facilitated mathematics teaching and learning, the stakeholders exhibited actualized interest to an ethnomathematics curriculum. When the lesson activities demanded much from the stakeholders in terms of cultural background knowledge and the teaching and learning implements, the stakeholders showed situational interest. The study also suggests that stakeholders' interests in an ethnomathematics curriculum are complex and interrelated, and are influenced more by external factors than by a given phenomenon. The findings also suggest that stakeholders had some concerns regarding an ethnomathematics curriculum and that these concerns were more complex and varied with each stakeholder according to how each viewed her/his role in the education process. The study's analysis of the stakeholders' receptiveness provides useful and important implications for relevant mathematics education, teacher education and above all, curriculum reform. It also highlights the importance of involving all those concerned with the education process to play major roles in the curriculum development process.

description: Castle Hewen has been known as an archaeological site for more than 400 years and has been variously linked to the medieval romances of King Arthur and to the possible sixth-century Owen Rheged. Aerial photographs taken in 1975 suggested that the site was much as described by W. Hutchinson in the 18th century. Limited excavations have demonstrated that the site was primarily of early Roman date with limited occupation in the late Roman period or the early sixth century.

XIAOOU LIU (Email: xiaoou2010@gmail.com, School of Agricultural Economics and Rural Development, Renmin University of China, Beijing, China 100872) RIGOBERTO LOPEZ (Professor and Department Head, Department of Agricultural and Resource Economics, Storrs, CT 06269) This paper quantifies the impact of Wal-Mart Supercenters on supermarkets’ profitability via a two-stage dynamic entry game, using simulated methods of moment and milk scanner data from Dallas/Fort Worth supermarkets. The empirical findings show that the entry of Wal-Mart Supercenters accounts for about an average of 50% decreases in profit margins for incumbent supermarkets. The effect of scale of economies is found to be more significant for Wal-Mart Supercenters than for incumbent supermarkets.

description: When using an optical profiler to measure rough surfaces, especially surfaces generated by metal additive manufacturing, topographical artifacts such as spikes on a reconstructed surface are nearly unavoidable. These may affect the determination of roughness parameters of the topography and lead to erroneous surface features. This paper proposes a new preprocessing method to eliminate most artifacts before extracting surface heights of rough surfaces measured by focus variation microscopy. In this method, the axial region where a surface height value is located with highest probability is estimated, based on datasets of planes parallel to the axial scanning direction. Results regarding height measurements with and without the proposed method are compared by measuring a Rubert Microsurf 329 comparator test panel for reference and a workpiece produced by metal additive manufacturing.

Extended $μ(J)$-rheology for dense suspensions at oscillatory shear flows

Year: 2020
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: Recent studies have highlighted that oscillatory and time-dependent shear flows might help increase flowability of dense suspensions. While most focus has been on cross-flows we here study a simple two-dimensional suspensions where we apply simultaneously oscillatory and stationary shear along the same direction. We first show that the viscosities in this set-up significantly decrease with an increasing magnitude of the oscillations, contrary to previous claims. The decrease can be attributed to the large decrease in the number of contacts and an altered microstructure as the magnitude of the oscillation is increased. As a sub-result we find both an extension to the $μ(J)$-rheology, a constitutive relationship between the shear stresses and the shear rate, valid for pure oscillatory flows and with a higher shear-jammed packing fraction for suspensions composed of frictional particles compared to steady-shear conditions.

description: We develop a formalism for treating coherent wave-packet dynamics of charge and spin carriers in degenerate and nearly degenerate bands. We consider the two-band case carefully in view of spintronics applications, where transitions between spin-split bands often occur even for relatively weak electromagnetic fields. We demonstrate that much of the semiclassical formalism developed for the single-band case can be generalized to multiple bands, and examine the nontrivial non-Abelian corrections arising from the additional degree of freedom. Along with the center of mass motion in crystal momentum and real space, one must also include a pseudo-spin to characterize the dynamics between the bands. We derive the wave packet energy up to the first order gradient correction and obtain the equations of motion for the real- and $k$-space center of the wave-packet, as well as for the pseudo-spin. These equations include the non-Abelian Berry curvature terms and a non-Abelian correction to the group velocity. As an example, we apply our formalism to describe coherent wave-packet evolution under the action of an electric field, demonstrating that it leads to electrical separation of up and down spins. A sizable separation will be observed, with a large degree of tunability, making this mechanism a practical method of generating a spin polarization. We then turn our attention to a magnetic field, where we recover Larmor precession, which cannot be obtained from a single-band point of view. In this case, the gradient energy correction can be regarded as due to a magnetic moment from the self-rotation of the wave-packet, and we calculate its value for the light holes in the spherical four-band Luttinger model.

description: The dynamics of non-equilibrium spin accumulation generated in metals or semiconductors by rf magnetic field pumping is treated within a diffusive picture. The dc spin accumulation produced in a uniform system by a rotating applied magnetic field or by a precessing magnetization of a weak ferromagnet is in general given by a (small) fraction of hbar omega, where omega is the rotation or precession frequency. With the addition of a neighboring, field-free region and allowing for the diffusion of spins, the spin accumulation is dramatically enhanced at the interface, saturating at the universal value hbar omega in the limit of long spin relaxation time. This effect can be maximized when the system dimensions are of the order of sqrt(2pi D omega), where D is the diffusion constant. We compare our results to the interface spin pumping theory of A. Brataas et al. [Phys. Rev. B 66, 060404(R) (2002)].

The analysis is based on a 140/fb data sample accumulated at the Upsilon(4S) resonance by the belle detector at the KEKB asymmetric-energy e+e- collider. We fully reconstruct one neutral B meson in the J/Psi pi0 final state. The accompanying B meson flavor is identified by its decay products. From the distribution of proper time intervals between the two B decays, we obtain the following CP-violating parameters: S_{J/Psi pi0}=-0.72+-0.42+-0.09 and A_{J/Psi pi0}=-0.01 +-0.29+-0.03.

description: Photoresists play a key role in the photolithographic process being necessary to print the structure layout of dies of microchips. Following Moore’s law leads to ever smaller assemblies reaching the single-digit nanometer range. Typical methods for quality assurance are scatterometry and atomic force microscopy facing challenges and disadvantages. Since overcoming the Abbe limit via superresolution techniques fluorescence microscopy can be another approach. This article describes the measurement analyses done with PALM/STORM on lithographical produced samples of positive resist doped with Atto 565. Lines with 200 nm thickness and equal spacing were studied. Thereby, ThunderSTORM provided better results than QuickPALM for data analysis. For the first experiment, using a permanently switched on 405 nm laser beam with low intensity shows the best resolution results. A rotating lambda half-wave plate in the second experiment leads to a slight increase of data quality. Further studies combining these two approaches will be carried out.

description: This paper relies on data associated 2,100 agricultural land sale transactions across two major Nebraska Watersheds (the Republican and Central Platte) over the 2000 to 2008 time period. The sales were spatially referenced (digitized into a GIS) in order to quantify and geo-spatially predict and map the implicit values of irrigation through the use of hedonic price modeling. Marginal implicit prices vary substantially across subwatersheds (natural resource districts), and the contribution of irrigation to sale prices is directly related to the extent to dependency of production agriculture on irrigation. This information is now currently being used to evaluate the economic efficiency of recent irrigation retirement programs and to help ensure that current and future retirement programs are cost-effective through targeting that retires irrigation land with the greatest hydrologic impact on water resources for the lowest cost.

description: Modeling online discourse dynamics is a core activity in understanding the spread of information, both offline and online, and emergent online behavior. There is currently a disconnect between the practitioners of online social media analysis -- usually social, political and communication scientists -- and the accessibility to tools capable of examining online discussions of users. Here we present evently, a tool for modeling online reshare cascades, and particularly retweet cascades, using self-exciting processes. It provides a comprehensive set of functionalities for processing raw data from Twitter public APIs, modeling the temporal dynamics of processed retweet cascades and characterizing online users with a wide range of diffusion measures. This tool is designed for researchers with a wide range of computer expertise, and it includes tutorials and detailed documentation. We illustrate the usage of evently with an end-to-end analysis of online user behavior on a topical dataset relating to COVID-19. We show that, by characterizing users solely based on how their content spreads online, we can disentangle influential users and online bots.

description: We construct finite element methods for the incompressible magnetohydrodynamics (MHD) system that precisely preserve magnetic and cross helicity, the energy law and the magnetic Gauss law at the discrete level. The variables are discretized as discrete differential forms in a de Rham complex. We present numerical tests to show the performance of the algorithm.

description: Ушбу тадқиқот Аффектив-респиратор пароксизм (АРП) билан оғриган болаларда оксидловчи стресс даражасини баҳолашга қаратилган. Натижаларга кўра, АРП гуруҳида малондиальдегид (MDA) даражаси юқори, супероксид дисмутаза (SOD) ва глутатион пероксидаза (GPx) фаолияти эса паст эканлиги аниқланди. Бу ҳолат оксидловчи стресснинг АРП патогенезида муҳим роль ўйнаши мумкинлигини кўрсатади. Илмий адабиётлар билан таққослаганда, ушбу натижалар АРП билан боғлиқ ҳолатларда антиоксидант ҳимоя тизими заифлашишини тасдиқлайди. Шундай қилиб, келажакдаги тадқиқотлар оксидловчи стрессни камайтиришга қаратилган терапия усулларини ўрганишга йўналтирилиши керак.
Archaeological investigation of a Roman road at Fairhill, Penrith, Cumbria
Creators: name: Jackson, David
Publisher: name: Archaeology Data Service

description: Transactions of the Cumberland & Westmorland Antiquarian & Archaeological Society, 19, 79-96
description: This paper presents the results of archaeological investigations undertaken by Wardell Armstrong LLP on land at Fairhill, Penrith, Cumbria. The investigation at the site has provided the opportunity to examine a section of the Roman road between Brougham and Old Penrith, which revealed details of the road construction and evidence for the continued use of the route into the 18th century. The work also revealed evidence for roadside activity, which comprised a number of cobbled surfaces and several cut features. Whilst the exact function of this has been difficult to interpret, such activity located alongside Roman roads is not well documented within the region, particularly away from forts and major settlements. The findings of the investigation at Fairhill have provided important details about the route and will add to the growing body of literature on the Roman road infrastructure within the county.

description: We report results of a project to map HCN and HCO+ J = 1-0 emission toward a sample of molecular clouds in the inner Galaxy, all containing dense clumps that are actively engaged in star formation. We compare these two molecular line tracers with millimeter continuum emission and extinction, as inferred from 13CO, as tracers of dense gas in molecular clouds. The fraction of the line luminosity from each tracer that comes from the dense gas, as measured by AV > 8 mag, varies substantially from cloud to cloud. In all cases, a substantial fraction (in most cases, the majority) of the total luminosity arises in gas below the AV > 8 mag threshold and outside the region of strong mm continuum emission. Measurements of the luminosity of HCN toward other galaxies will likely be dominated by such gas at lower surface density. Substantial, even dominant, contributions to the total line luminosity can arise in gas with densities typical of the cloud as a whole (densities about 100 per cubic cm). Defining the dense clump from the HCN or HCO+ emission itself, similarly to previous studies, leads to a wide range of clump properties, with some being considerably larger and less dense than in previous studies. HCN and HCO+ have similar ability to trace dense gas for the clouds in this sample. For the two clouds with low virial parameters, the 13CO is definitely a worse tracer of the dense gas, but for the other four, it is equally good (or bad) at tracing dense gas.

Zero Temperature Dynamics of 2D and 3D Ising Ferromagnets

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We consider zero-temperature, stochastic Ising models with nearest-neighbor interactions in two and three dimensions. Using both symmetric and asymmetric initial configurations, we study the evolution of the system with time. We examine the issue of convergence of the dynamics and discuss the nature of the final state of the system. By determining a relation between the median number of spin flips per site, the probability p that a spin in the initial spin configuration takes the value +1, and lattice size, we conclude that in two and three dimensions, the system converges to a frozen (but not necessarily uniform) state when p is not equal to 1/2. Results for p=1/2 in three dimensions are consistent with the conjecture that the system does not evolve towards a fully frozen limiting state. Our simulations also uncover `striped' and `blinker' states first discussed by Spirin et al., and their statistical properties are investigated.

The purpose of Hadrian's Wall
Creators: name: Symonds, Matthew
Publisher: name: Archaeology Data Service

description: Transactions of the Cumberland & Westmorland Antiquarian & Archaeological Society, 19, 97-122
description: Seeking to understand the purpose of Hadrian's Wall is essential to determining its impact at a local and regional level. While the controls that the new border imposed must have changed the nature of life on the Tyne - Solway isthmus, so too the various communities present within this zone would have exerted an influence on how the Roman army sought to tighten control. The uniformity of the overarching frontier concept allows anomalies along its course to be identified, potentially opening a window into military priorities. Blocking or redirecting traditional routes crossing the Wall line appear to be key objectives, while the numerous irregularities in and around the Tipalt - Irthing gap indicate that it was a point of particular concern.
AGRICULTURAL AND FOOD TRADE IN CENTRAL AND EASTERN EUROPE: THE CASE OF SLOVENIAN INTRA-INDUSTRY TRADE

description: One of the striking features in Central and Eastern European (CEE) countries is the deterioration of their agricultural and food trade balance during transition to a market economy as imports increased faster than exports or exports even declined. This paper investigates the Slovenian agricultural and food trade in more detail focusing on changes in the geographical distribution of trade and the nature of trade specialization on the basis of the Grubel-Lloyd Intra-Industry Trade index and Marginal Intra-Industry Trade Indices. The results indicate that Slovenian agricultural and food trade largely remains of the inter-industry type with specialisation of exports towards the former Yugoslav markets and imports from the European Union. The proportion of intra-industry trade was especially low for bulk commodities with little or no processing. A major explanations for these findings is that despite the "free" trade agreements Slovenia signed with the EU and countries of Central and Eastern Europe the level of protection in the agricultural and food sector has remained rather high. Due to EU membership Slovenia faces now direct competition in a market of 25 countries. This intensifies the restructuring process in the Slovenian agricultural and food sector. Due to the present low level of IIT this likely induces rather high adjustment costs since restructuring and reallocation of factors will have to occur between and not within industries.
