description: Counter-rotating vortices in miscible two-component Bose-Einstein condensates, in which superflows counter-rotate between the two components around the overlapped vortex cores, are studied theoretically in a pancake-shaped potential. In a linear stability analysis with the Bogoliubov-de Gennes model, we show that counter-rotating vortices are dynamically unstable against splitting into multiple vortices. The instability shows characteristic behaviors as a result of countersuperflow instability, which causes relaxation of relative flows between the two components in binary condensates. The characteristic behaviors are completely different from those of multiquantum vortices in single-component Bose-Einstein condensates; the number of vortices generated by the instability can become larger than the initial winding number of the counter-rotating vortex. We also investigate the nonlinear dynamics of the instability by numerically solving the Gross-Pitaevskii equations. The nonlinear dynamics drastically changes when the winding number of counter-rotating vortices becomes larger, which lead to nucleation of vortex pairs outside of the vortex core. The instability eventually develops into turbulence after the relaxation of the relative rotation between the two components.

description: We present a collection of zero-, one- and two-quantum two-dimensional coherent spectra of excitons and trions in a CdTe/(Cd,Mg)Te quantum well. The set of spectra provides a unique and comprehensive picture of the exciton and trion nonlinear optical response. Exciton-exciton and exciton-trion coherent coupling is manifest as distinct peaks in the spectra, whereas signatures of trion-trion interactions are absent. Excellent agreement using density matrix calculations is obtained, which highlights the essential role of many-body effects on coherent interactions in the quantum well.

description: The paper investigates the use of low-diffusion (contact-discontinuity-resolving [Liou M.S.: {\em J. Comp. Phys.} {\bf 160} (2000) 623--648]) approximate Riemann solvers for the convective part of the Reynolds-averaged Navier-Stokes (\tsn{RANS}) equations with Reynolds-stress model (\tsn{RSM}) closure. Different equivalent forms of the \tsn{RSM-RANS} system are discussed and classification of the complex terms introduced by advanced turbulence closures is attempted. Computational examples are presented, which indicate that the use of contact-discontinuity-resolving convective numerical fluxes, along with a passive-scalar approach for the Reynolds-stresses, may lead to unphysical oscillations of the solution. To determine the source of these instabilities, theoretical analysis of the Riemann problem for a simplified Reynolds-stress transport model-system, which incorporates the divergence of the Reynolds-stress tensor in the convective part of the mean-flow equations, and includes only those nonconservative products which are computable (do not require modelling), was undertaken, highlighting the differences in wave-structure compared to the passive-scalar case. A hybrid solution, allowing the combination of any low-diffusion approximate Riemann solver with the complex tensorial representations used in advanced models, is proposed, combining low-diffusion fluxes for the mean-flow equations with a more dissipative massflux for Reynolds-stress-transport. Several computational examples are presented to assess the performance of this approach.

description: Statistical uncertainty of different filtration techniques for market network analysis is studied. Two measures of statistical uncertainty are discussed. One is based on conditional risk for multiple decision statistical procedures and another one is based on average fraction of errors. It is shown that for some important cases the second measure is a particular case of the first one. Statistical uncertainty for some popular market network structures is analyzed. Results of numerical evaluation of statistical uncertainty for minimum spanning tree, market graph, maximum cliques and maximum independent sets are given. The most stable structures are derived.

description: Half-Heusler (HH) alloys have attracted considerable interest as promising thermoelectric (TE) materials in the temperature range around 700 K and above, which is close to the temperature range of most industrial waste heat sources. The past few years have seen nanostructuing play an important role in significantly enhancing the TE performance of several HH alloys. In this article, we briefly review the recent progress and advances in these HH nanocomposites. We begin by presenting the structure of HH alloys and the different strategies that have been utilized for improving the TE properties of HH alloys. Next, we review the details of HH nanocomposites as obtained by different techniques. Finally, the review closes by highlighting several promising strategies for further research directions in these very promising TE materials.

description: The aim of the current research is to eliminate the Cu(II) ions from aqueous solution using biochar, namely sulphuric acid-modified Annona reticulata seeds (SMARS). The removal process followed the Freundlich and pseudo-first-order models. At optimum conditions, Langmuir adsorption capacity of the SMARS for Cu(II) ions was calculated as 561.1 mg/g. The results of this work indicate that the adsorption was feasible, spontaneous and exothermic, which was controlled by film diffusion. An adsorber has been designed based on Freundlich model. Desorption results indicate that 0.2 N of the hydrochloric acid solution provides the maximum elimination of heavy metals from the Cu(II) ions loaded adsorbent. The column influencing parameters like Cu(II) ions concentration, bed height and flow rate have been experimented. The best operating condition for removal of Cu(II) ions by SMARS in column mode of operation has been recorded as flow rate = 5 mL/min, bed height = 8 cm, adsorbent amount = 16 g, solution pH = 6.0 and at the temperature = 30°C. The column experimental data have been characterised by applying Bed Depth Service Time and Thomas models. The results indicate that the SMARS has exceptional adsorption behaviour in the elimination of heavy metals from the aqueous solution.

description: This study investigates the consequences of suburban poverty on meeting two primary goals of the HUD-administered housing choice voucher (HCV) program: to de-concentrate inner-city poverty and to extend greater access to opportunities that enable socioeconomic mobility. Recent studies have shown that housing choice vouchers have been spreading away from central cities into the suburbs. While promising, the quality of many of these suburban neighborhoods no longer aligns with the idealistic notions of suburban opportunity. This paper measures the quality of the neighborhoods in which voucher-occupied households are located. It then compares the quality of suburban and urban neighborhoods by using composite neighborhood quality and opportunity structure indices. The data confirm a decentralization of vouchers but highlight re-clustering in low-quality and opportunity-poor suburbs. Secondly, although suburban neighborhoods collectively are of higher quality, their opportunity structures are relatively weak. Furthermore, there is an inverse relationship between neighborhood quality and the proportion of voucher-occupied households regardless of racial makeup and metropolitan location. Atlanta’s public housing authorities need to engage in more intentional strategies to help families move to opportunity-rich neighborhoods and to work past existing barriers to geographic mobility. Future policy objectives need to encourage inter-municipality collaboration and to target federal and state aid for neighborhood development.
A Robust Variational Model for Positive Image Deconvolution

description: In this paper, an iterative method for robust deconvolution with positivity constraints is discussed. It is based on the known variational interpretation of the Richardson-Lucy iterative deconvolution as fixed-point iteration for the minimisation of an information divergence functional under a multiplicative perturbation model. The asymmetric penaliser function involved in this functional is then modified into a robust penaliser, and complemented with a regulariser. The resulting functional gives rise to a fixed point iteration that we call robust and regularised Richardson-Lucy deconvolution. It achieves an image restoration quality comparable to state-of-the-art robust variational deconvolution with a computational efficiency similar to that of the original Richardson-Lucy method. Experiments on synthetic and real-world image data demonstrate the performance of the proposed method.

description: Despite the fact that many states have increased their high school graduation requirements over the last several years, too many graduates are still underprepared for college (Bailey, 2009) and the workforce (Symonds, Schwartz, Ferguson, 2011). Reasons for this underpreparedness include, among other factors: (1) a lack of clear information on students’ progress toward college and career readiness during the high school years that could allow students to address gaps in knowledge and skills, and (2) a mismatch between what high schools teach and the expectations of colleges and employers (Venezia, Kirst, Antonio, 2003). An approach is emerging to remedy this issue. States across the country are administering assessments that measure 11th grade students’ readiness to successfully perform entry-level, credit-bearing postsecondary coursework. Early college readiness assessments can inform students of additional skills they need to gain in mathematics, reading, or writing to enter college without the need for remediation. As a further step, some states are combining early college readiness assessments with structured interventions, which we call transition curricula, for students who are not college ready. Transition curricula consist of a course, a set of modules, online tutorials, or other educational experiences offered no later than 12th grade to students who are at risk of being placed into remedial mathematics, reading, or writing when they enter college (Kannapel, 2012). The availability of transition curricula means that students will no longer need to figure out how to improve their college readiness on their own; rather, they can enroll in a course or other activity in an attempt to attain a higher level of preparation, which might possibly help them avoid remediation (known also as developmental education) altogether. Taken together, early college readiness assessments and transition curricula have the potential to transform the senior year of high school and reconceptualize the high school to college pathway.

description: We discuss 94 Extended Green Objects (EGOs) in the northern Galactic plane cataloged by Cyganowski et al, based on near-infrared narrowband H2 (2.122 μm and continuum observations from the United Kingdom Infrared Telescope. This data set is three times larger than our previous study, and is unbiased by preselection. As discussed in the previous paper, the morphologies of the 4.5 μm emission generally resemble those of the near-infrared continuum, but are different from those of the H2 emission. Of our sample, only 28% of EGOs with H2 emission show similar morphologies between 4.5 μm and H2 emission. These results suggest that the 4.5 μm emission mainly comes from scattered continuum from the embedded young stellar object (YSO), and partially from H2 emission. About half of EGOs are associated with H2 outflows, if the H2 outflow incompleteness is considered. The H2 outflow detection rate for EGOs with K-band detections (61%) is significantly higher than for those without K-band detections (36%). This difference may be due to the fact that both H2 and K-band emissions are associated with outflows, i.e., H2 emission and K-band continuum are associated with shocks and outflow cavities, respectively. We also compared the correlation between the H2 outflows and Class I 44 GHz methanol masers from literature. The methanol masers can be located upstream or downstream of the H2 outflows and some bright H2 spots or outflows are not associated with methanol masers, suggesting that methanol masers and H2 emission trace different excitation conditions.

description: This paper reviews current research on the effectiveness of interventions and reforms that seek to improve the math preparedness and success of high school students entering college. Based on gaps in the research knowledge, it also provides recommendations for further inquiry in particular areas. The studies reviewed here are selected from research conducted by the Community College Research Center (CCRC) and the National Center for Postsecondary Research (NCPR), from searches of the Education Full Text database for peer-reviewed articles, and from searches of Google Scholar for high-quality reports. The two key criteria for inclusion in the review are that (1) the study in question focuses on (a) an early assessment program in math; (b) a math bridge, boot camp, or brush-up; (c) a reform of developmental math; or (d) improvements to math instruction; and that (2) at least one of the study’s outcomes is related to changes in math or college performance. To evaluate the evidence, I report on each study’s design and findings. I also calculate each intervention’s effect size and categorize the effect size to compare impacts across the studies under review. Overall, the evidence is limited, but some of the interventions and reforms appear promising. The evidence on early assessment is minimal. The evidence on bridges, boot camps, and brush-ups suggests that short-term programs may only have short-term impacts. The evidence on different models of developmental reform varies depending on the reform model. For dominant models, it is positive (for compression models), insignificant (for learning communities), or negative (for modularization). For less prevalent models, it is positive (for mainstreaming) or needs further research (for statistics pathways). In terms of innovations that are strictly pedagogical, the strongest positive evidence is found for using structured forms of student collaboration and for building conceptual understanding through the use of multiple representations when teaching and solving problems. The evidence on computer-mediated instruction in the developmental math classroom is very mixed, with some studies finding positive effects and others finding negative effects.

description: A low-cost and selective solid phase extractor (SPE) for complete removal of chromium (VI) sp cies from aqueous media has been developed. The proposed method was based upon formation of chlorochromate [CrClO3]−aq oxyanion in aqueous HCl (≥ 0.5 mol/L) medium followed by complete extraction onto the ion pairing 2,3,5-triphenyltetrazolium chloride (TZ+Cl−) modified α-Fe2O3 nanoparticles treated polyurethane foam (PUFs) (TZ+Cl−/α-Fe2O3 NPs/PUFs) solid phase platform. The sorption data fitted well pseudo-second-order kinetic with an overall rate constant (k2) of 0.010 g (mg. min)−1. The values of ΔH (−78.2 ± 2.1 kJ mol−1) and ΔG (−3.51 ± 1.1 kJ mol−1) revealed that, the [CrClO3]−aq sorption onto the solid sorbent are spontaneous and exothermic process, respectively. The value of ΔS (223.5 ± 2.5 J mol−1 K−1 reflects the sorption of [CrClO3]−aq onto the TZ+Cl−/α-Fe2O3 NPs/PUFs sorbent proceeded in a more random fashion. The nanocomposite sorbent packed column was successfully used for complete removal of trace levels of chromium (VI) species from environmental water samples. The retained chromium (VI) species were recovered with NaOH (0.5 M) and analysed by ICP-OES. Sorbent packed column was also used for rapid and complete retention of chromium(III) after oxidation with H2O2 in KOH. The sorbent packed column can be reused for 3–4 times without decrease (±5%) in column performance.

description: To develop policies aimed at increasing student success and institutional effectiveness, it is useful for colleges to understand when students reach significant academic milestones, what students do if they exit college before completion, and whether the timing of these events differs among students with different levels of academic preparedness. Research suggests that students who reach important milestones early in their college careers are more likely than others to achieve their education goals (Edgecombe, 2011). And knowing when particular kinds of students reach academic milestones (or when they exit college without attaining a degree) can shed light on common patterns of student progression (Moore and Shulock, 2009). This report examines how the timing of important events in community college student progression— reaching program concentration by earning nine college-level credits in a single area of study, completing a program of study, and exiting college prior to program completion—differs by students who upon entry to college are deemed college ready or are referred to developmental education in either one, two, or three subject areas. It also examines the timing of additional post-exit education outcomes of students who leave their first college prior to program completion. Using five years of course-level transcript data on 14,617 first-time-in-college students who in the 2005-06 academic year enrolled in one of eight community colleges across three different states, this descriptive analysis identifies in which term students at various levels of college preparedness reached program concentration, earned a degree or certificate, or exited college without completing a program. Students who entered community college as college ready in math, reading, and writing (16 percent of students in the sample) are compared to students who were referred to developmental education in one (32 percent), two (21 percent), or all three (31 percent) of those subject areas.

The data obtained were compared with the permissible limit set for drinking water by the Codex Alimantarius (CA), United States Environmental Protection Agency (USEPA), Food and Agriculture Organization/World Health Organization (FAO/WHO) and National Standard of Iran (NSI). The highest mean level was 84.11 ± 27.06 μg/L is related to Fe and the lowest was Cr > Pb > Ni > Al > Ba. Target hazard quotient index of toxic elements, for adults and children, was considerably lower than the safe risk limits THQ > 1.

description: Potentially toxic elements (PTEs) are a major concerns from food safety, environmental, and ecological points of view. In this study, the concentration of Arsenic (As), Lead (Pb), Mercury (Hg), Nickel (Ni), Cadmium (Cd), Copper (Cu), Chromium (Cr) and Zinc (Zn) in corn and soybean samples collected from Tehran’s market was investigated by the aid of an Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). Besides, the percentile 95% target hazard quotient (THQ) and carcinogenic risk (CR) for adults’ and children’s consumers were estimated using the Monte Carlo Simulation (MCS) technique. The range concentration of As, Cd, Pb, Ni, Cr, Cu and Zn detected in corn samples was <0.001 to 0.025, <0.001 to 0.003, 0.001 to 0.108, 0.060 to 0.193, 0.212 to 0.363, 0.061 to 0.114, and 1.178 to 1.701 mg/kg, respectively, while the corresponded values for soybean samples were <0.001 to 0.036, 0.001 to 0.005, 0.002 to 0.125, 0.138 to 1.025, 0.055 to 1.054, 0.333 to 0.799, 1.518 to 3.893, mg/kg, respectively. The mean concentration of PTEs in all samples was less than the maximum permitted level recommended by EU standards. The result of the health risk assessment shows that consumers are not at substantial non-carcinogenic and carcinogenic risk due to ingestion of PTEs via consumption of corn and soybean. Consequently, although there is no necessity for urgent action, efforts to sustain these conditions are crucial to warrant public health.

Analytical results for the survival probability and first-passage density based on the fractional Fokker-Planck equation are shown to agree well with Monte Carlo simulations results. As an application we discus an improved deign for efficient translocation of gradient copolymers compared to homopolymer translocation in a quasi-equilibrium approximation.

Nationally, about 70 percent of community college students report pursuing Associate of Arts (A.A.) or Associate of Science (A.S.) degrees. These degrees are also called general education or transfer degrees because they are usually designed for students intending to transfer to a four-year college and pursue a bachelor’s degree.1 Students in transfer-oriented degree programs are primarily liberal arts and humanities majors or academic, non-applied STEM majors.2 These programs often require that students complete a general education “core curriculum.” Tracking student progression through this core curriculum is therefore an important means for community colleges to better understand the performance of large numbers of students who plan to go on to earn a bachelor’s degree. This report demonstrates useful methods for examining student progression through the core curriculum. We carry out analyses at two colleges in two different states, illustrating students’ overall progression through the core curriculum and the relationship of this “core” progression to their college outcomes. By means of this analysis, we are able to identify core curriculum subject areas in which students do well and those in which they struggle, shedding light on courses and subject areas college administrators and faculty may want to target in order to improve outcomes for their students. Our analyses use data from two states with different transfer policies. In one state (State A), legislation requires all public two-year and four-year colleges to offer a 42-credit general education core curriculum. The state mandates that all core curriculum courses completed at one public college are transferable to another public college. However, the state does not have an articulation agreement that guarantees junior standing for transfer students who have completed the core and attained an associate degree. So while students’ core credits will transfer, other courses completed at the community college are not guaranteed to transfer. In the second state (State B), public two- and four-year colleges are required to have a 36-credit core curriculum. In addition, statewide articulation agreements guarantee junior standing at four-year public universities for transfer students who have completed the core and attained an associate degree.

description: We consider a point particle moving in a random distribution of obstacles described by a potential barrier. We show that, in a weak-coupling regime, under a diffusion limit suggested by the potential itself, the probability distribution of the particle converges to the solution of the heat equation. The diffusion coefficient is given by the Green-Kubo formula associated to the generator of the diffusion process dictated by the linear Landau equation.

description: "So goes the popular concept of defense conversion or whatever you call it (diversification, economic adjustment, military transition, defense reinvestment...). The central tenet of conversion asserts that companies which produce goods for the defense market can be guided, with a little effort, toward a successful civilian market. The benefits to the country could be immense. Labor and machinery reserved for defense could be retrained and retooled for civilian use. Rebuilding the infrastructure, developing civilian technologies, and shoring-up the nation's economic competitive edge are all plausible options.
However, those grandiose designs of a new civilian economy are not the reasons why conversion is a favorite in Washington. The real motive for conversion is jobs. Defense cutbacks will have a crippling effect on private industry. Everyone knows that the Department of Defense(DoD) is a tremendous stimulant to the economy. Along with the Pentagon, it practices a de facto industrial policy, subsidizing key technologies and investing in basic and applied research and development (R and D). This high-tech research is spunoff, giving the products of civilian firms a competitive boost over foreign products. But as defense funds begin to taper off, bases will close, military personnel dismissed, and defense contractors starved for income, triggering a new wave of unemployment..."--from page 10

description: The bio-sorption is the using of biological biomasses, live or dead form, for heavy metals removal from polluted wastewater. In the current work, live planktonic Nostoc sp. cells were used for hexavalent Chromium [Cr(VI)] elimination from Cr-contaminated wastewater. Optimisation process was achieved in order to obtain the optimum conditions that help achieving the highest Cr(VI) removal efficiency. For instance, One Factor At a Time ‘OFAT’ experiments were performed for the determination of the coded factors levels (low/high levels) that can be included in the Full factorial design experiment ‘many interacted factors at a time’. Afterwards, a small reactor design was implemented to develop Nostoc sp. algal biofilm. After that, the algal biofilm was applied in the Cr(VI) removal process to facilitate harvesting and dewatering of the biomass after the treatment process. Results showed that, live planktonic Nostoc sp. achieved the highest Cr(VI) removal efficiency of 98.16%at 100 ppm after 7 days contact time. Furthermore, Nostoc sp. stated its great ability to form a biofilm on polystyrene substrate which achieved the highest Cr(VI) removal of ‘86.498%’ at a concentration of 100 ppm after 7 days contact time. Some characterisation techniques such as Fourier Transform Infrared spectroscopy (FT-IR) and Scanning Electron Microscopy (SEM) analyses were applied on the developed biofilm of Nostoc sp. Isotherm and kinetics were investigated for the Cr(VI) removal process using Nostoc sp. biofilm.

Signatures of particle decay in 21 cm absorptions from first minihalos

description: The imprint of decaying dark matter (DM) particles in characteristics of the "21 cm fores" -- absorptions in 21 cm from minihalos in spectra of distant radio-loud sources -- is considered within a 1D self-consistent hydrodynamic description of minihalos from their turnaround point to virialization. The most pronounced influence of decaying DM on evolution of minihalos is found in the mass range $M=10^5-10^6\msun$, for which unstable DM with the current upper limit of the ionization rate $ξ_{L} = 0.59\times 10^{-25}$ s$^{-1}$ depresses 21 cm optical depth by an order of magnitude compared to the standard recombination scenario. Even rather a modest ionization $ξ\sim 0.3ξ_L$ practically "erases" absorption features and results in a considerable decrease (by factor of more than 2.5) of the number of strong ($W_ν^{obs} \simgt 0.3$ kHz at $z\simeq 10$) absorptions. At such circumstances broad-band observations are to be more suitable for inferring physical conditions of the absorbing gas. X-ray photons from stellar activity of initial episodes of star formation can compete the contribution from decaying DM only at $z<10$. Therefore, when observed the 21 cm signal will allow to follow evolution of decaying DM particles in the redshift range $z=10-15$. Contrary, in case of non-detection of the 21 cm signal in the frequency range $ν<140$ MHz a lower limit on the ionization rate from decaying dark matter can be established.

description: In this study, a Quick, Easy, Cheap, Effective, Rugged and Safe method (QuEChERS) method was optimised to extract 30 pesticides which are the most used in Egypt in soil and drainage water. Optimisation was performed by Experimental Design expert 7.1 to get better recoveries. The procedure combined with a developed GC-MS for determination of these pesticides. Total analysis time was 36 min with 1 ml injection volume. The limit of quantification (LOQ) was ranged between 4.59 ng/ml, and 15.91 ng/ml for all pesticides. Most standard deviations were in the range between 0.41 and 1.41 indicating satisfactory accuracy. The validated method was applied to Egyptian soil and drainage water samples brought from different places in Damietta city. Dimethoate, β-Endosulfan, DDD, Malathion, Vinclozolin, DDT, Endrin, Cyprodinil, Primiphos ethyl, Tetradifon, Parathion ethyl and Diazinon were detected and quantified. So risk assessment on human health should be considered especially for those pesticides.
