description: Reconnections of quantum vortex filaments create sharp bends which degenerate into propagating Kelvin waves. These waves cascade their energy down-scale and their waveaction up-scale via weakly nonlinear interactions, and this is the main mechanism of turbulence at the scales less than the inter-vortex distance. In case of an idealised forcing concentrated around a single scale k0, the turbulence spectrum exponent has a pure direct cascade form -17/5 at scales k>k0 and a pure inverse cascade form -3 at k

      Präsident der Vereinigten Arabischen Emirate (VAE) Scheich
      Khalifa bin Zayed ein Anti-Terror-Gesetz mit einer weit
      gefassten Terrorismus-Definition. Danach gelten alle Personen
      als Terroristen, die eine Handlung begehen, die direkt oder
      indirekt terroristische Folgen nach sich ziehen könnte. Human
      Rights Watch (HRW) kritisierte, dass diese Definition
      missbraucht werden könne, um Grundrechte wie Rede- und
      Versammlungsfreiheit einzuschränken. Die Befürchtung von HRW
      bestätigte sich mit der Veröffentlichung der emiratischen
      Terrorliste am 15.11.2014, auf der insgesamt 85
      Organisationen, darunter die Muslimbruderschaft inklusive
      zahlreicher Ableger, aufgelistet wurden. Bereits im Dezember
      2013 hatte Ägypten die Muslimbruderschaft zu
      Terrororganisation erklärt, im März 2014 folgte
      Saudi-Arabiena. Die Emirate und Saudi-Arabien hatten die
      Vorbereitungen des Putsches des ägyptischen Militärs gegen
      Präsident Mursi finanziell und logistisch unterstützt.
      Seitdem koordinieren die drei Länder weitgehend ihre
      regionale Sicherheitspolitik sowie ihr internationales
      Auftreten. Im Folgenden werden die auf der Terrorliste
      aufgeführten Organisationen kategorisiert und kurz
      beschrieben. Die Anti-Terrorpolitik der VAE wird in den
      regionalen Kontext eingeordnet und Ziele sowie

description: The purpose of this study was to examine the effects of the Kodály Music Methodology on the reading fluency of second grade students. The participants in this study were enrolled in a Baltimore County Public School for the 2013-2014 school year. All of the students received the Baltimore County Public Schools Music Curriculum while the treatment group was instructed primarily in the Kodály Methodolgy. The treatment group also participated in a take home study that focused on music literacy, sight reading, and pitch exploration all outlined by the Kodály Method. The study lasted over the course of 6 weeks with the participants receiving 50 minutes of instruction once a week, and then at home practice that was monitored by parents. While both groups increased their score on the post-test, the null hypothesis was retained.

description: Electric motors can be damaged or operate improperly from a possible set of failures. Such failures are related to high or very low voltage and current levels, phase loss or blocked rotor. Therefore, it is important to protect these equipments through appropriate mechanisms. Alternatively, a workbench can simulate detectable failures related to the engines, allowing to change parameters, in which maintenance operators are able to identify the results of these changes. This work presents the development of a workbench as a tool for testing electrical machines and drives. The workbench is based on the Arduino programming platform (microcontroller system), in which it checks the functioning of electric motors under the condition of failures that may occur in this engine. Motor protections are carried out through an Intelligent Electronic Device (IED), which are popularly known as intelligent relays. The results show the development of a workbench that can test and identify several faults in a small three-phase motor.

description: Algorithmic decision-making is increasingly being used by companies to reduce costs and enable their employees to make better-informed decisions. However, algorithmic systems can be biased, resulting in decisions that systematically disadvantage certain groups. This research aims to examine how users of algorithmic systems respond to algorithmic bias. Furthermore, we aim to analyze how users of algorithmic systems morally reason about algorithmic bias. In this short paper, we propose a theoretical model of two moral reasoning processes – moral decoupling and moral disengagement – and outline a research design to study how these reasoning processes impact users’ continued use of algorithmic systems. Findings from our pilot study suggest that users follow diverse usage patterns when faced with algorithmic bias, with most participants discontinuing using the algorithmic system. Our research contributes to the literature on algorithmic bias by providing insights into how users of algorithmic systems respond to and morally reason about algorithmic bias.

description: Aims: An all-sky survey of loop- and arc-like intensity enhancements has been performed in order to investigate the large-scale structure of the diffuse far-infrared emission. Methods: We used maps made of 60 and 100 micrometer processed IRAS data (Sky Survey Atlas and dust infrared emission maps) to identify large-scale structures: loops, arcs or cavities, in the far-infrared emission in the Galaxy. Distances were attributed to a subsample of loops using associated objects. Results: We identified 462 far-infrared loops, analyzed their individual FIR properties and their distribution. This data forms the Catalogue of Far-Infrared Loops in the Galaxy. We obtained observational estimates of f_in~30% and f_out~5% for the hot gas volume filling factor of the inward and outward Galactic neighbourhood of the Solar System. We obtained a slope of the power law size luminosity function {beta}=1.37 for low Galactic latitudes in the outer Milky Way. Conclusions: Deviations in the celestial distribution of far-infrared loops clearly indicate, that violent events frequently overwrite the structure of the interstellar matter in the inner Galaxy. Our objects trace out the spiral arm structure of the Galaxy in the neighbourhood of the Sun and their distribution clearly suggests that there is an efficient process that can generate loop-like features at high Galactic latitudes. Power law indices of size luminosity distributions suggest, that the structure of the ISM is ruled by supernovae and stellar winds at low Galactic latitudes while it is governed by supersonic turbulence above the Galactic plane.

description: The purpose of this study was to determine what effect stereotype threat might have on student success on the PSAT when the students attend a school composed primarily of minority students. The participants were enrolled in a county school’s Gifted and Talented and Honors Geometry classes during the 2013-2014 school year. The first measurement tool had participants complete a survey on stereotype threat and student performance. These answers were linked to the student PSAT scores, which was used as a second measurement tool. This study implemented a descriptive design. The data collected was analyzed for patterns based on student responses and the mean PSAT scores of students that felt similarly. Findings showed that the participants that felt the pressure of stereotype threat and felt that they were accountable for their actions had higher mean PSAT scores than their peers on the PSAT.

description: The purpose of this study was to determine whether teaching select reading strategies would improve the academic achievement of fifth grade students in the area of reading comprehension. For this quasi-experimental study, students in a fifth grade reading class were randomly assigned to a treatment group who received traditional comprehension instruction with additional reading strategy instruction, or assigned to a control group which received the traditional comprehension instruction only. A pre and post assessment design was used in this study. The analysis of this study suggested significant improvement in reading performance for students provided with direct instruction in reading. The promising results and other research suggests that direct reading strategy instruction can improve reading comprehension scores in fifth grade students. Implications of the results and future research are discussed within the paper.

With this data, considered for years 2012-2018, we determined the world trade impact of the Kernel of EU 9 countries (KEU9), being Austria, Belgium, France, Germany, Italy, Luxembourg, Netherlands, Portugal, Spain, considered as one united country. We apply the advanced Google matrix analysis for investigation of the influence of KEU9 and show that KEU9 takes the top trade network rank positions thus becoming the main player of the world trade being ahead of USA and China. Our network analysis provides additional mathematical grounds in favor of the recent proposal of KEU9 super-union which is based only on historical, political and economy basis.

description: For the first time, limits on double-beta processes in $^{74}$Se have been obtained using a 400 cm$^3$ HPGe detector and an external source consisting of natural selenium powder. At a confidence level of 90%, they are $1.9\times 10^{18}$ y for the $β^+$EC$(0ν+ 2ν)$ transition to the ground state, $7.7\times 10^{18}$ y for the ECEC($2ν$) transition to the $2^+_1$ excited state in $^{74}$Ge (595.8 keV), $1.1\times 10^{19}$ y for the ECEC($0ν$) transition to the $2^+_1$ excited state in $^{74}$Ge (595.8 keV) and $5.5\times 10^{18}$ y for the ECEC($2ν$) and ECEC($0ν$) transitions to the $2^+_2$ excited state in $^{74}$Ge (1204.2 keV). The last transition is discussed in association with a possible enhancement of the decay rate, in this case by several orders of magnitude, because the ECEC$(0ν)$ process is nearly degenerate with an excited state in the daughter nuclide. Prospects for investigating such processes in future experiments are discussed.

The Effects of Perceived Parental Involvement and Value of Achievement on Student Achievement in Inner-City African American 7th Grade Males

description: This correlational study examined the relationships between perceptions parental involvement, beliefs about work and achievement, and students’ academic achievement. Previous research indicates that parental involvement in school activities benefits students’ academic success. However, the definition of “parental involvement” varies between ethnic, racial, and socioeconomic groups. Previous research has indicated that one program or type of “involvement” does not have the same effect for all students, and in fact, different populations require different levels and types of involvement to ensure success. The current study used a convenience sample and examined correlations between both students’ and parents’ perceptions of parental involvement, personal achievement values, and students’ actual academic achievement, defined by their GPA’s. No significant correlations were found between parental involvement, personal beliefs about achievement, and GPA. However, significant positive correlations were found between students’ and parents’ ratings of parental involvement and their beliefs about work and achievement, suggesting these perceptions were in accord with one another. While results of the study were inconclusive in determining the effectiveness of values and parental involvement on grades, they did yield some interesting findings and considerations for future research in this area.

description: Recurrent cortical networks provide reservoirs of states that are thought to play a crucial role for sequential information processing in the brain. However, classical reservoir computing requires manual adjustments of global network parameters, particularly of the spectral radius of the recurrent synaptic weight matrix. It is hence not clear if the spectral radius is accessible to biological neural networks. Using random matrix theory, we show that the spectral radius is related to local properties of the neuronal dynamics whenever the overall dynamical state is only weakly correlated. This result allows us to introduce two local homeostatic synaptic scaling mechanisms, termed flow control and variance control, that implicitly drive the spectral radius towards the desired value under working conditions. We demonstrate the effectiveness of the two adaptation mechanisms under different external input protocols and the network performance after adaptation by training the network to perform a time-delayed XOR operation on binary sequences. As our main result, we found that flow control reliably regulates the spectral radius for different types of input statistics. Precise tuning is however negatively affected when interneural correlations are substantial. Furthermore, we found a consistent task performance over a wide range of input strengths/variances. Variance control did however not yield the desired spectral radii with the same precision, being less consistent across different input strengths. Given the effectiveness and remarkably simple mathematical form of flow control, we conclude that self-consistent local control of the spectral radius via an implicit adaptation scheme is an interesting and biological plausible alternative to conventional methods using setpoint homeostatic feedback controls of neural firing.

Nuclear Modification Factor for Charged Pions and Protons at Forward Rapidity in Central Au+Au Collisions at 200 GeV

description: We present spectra of charged pions and protons in 0-10% central Au+Au collisions at $\sqrt{s_{NN}}=200$ GeV at mid-rapidity ($y=0$) and forward pseudorapidity ($η=2.2$) measured with the BRAHMS experiment at RHIC. The spectra are compared to spectra from p+p collisions at the same energy scaled by the number of binary collisions. The resulting nuclear modification factors for central Au+Au collisions at both $y=0$ and $η=2.2$ exhibit suppression for charged pions but not for (anti-)protons at intermediate $p_T$. The $\bar{p}/π^-$ ratios have been measured up to $p_T\sim 3$ GeV/$c$ at the two rapidities and the results indicate that a significant fraction of the charged hadrons produced at intermediate $p_T$ range are (anti-)protons at both mid-rapidity and $η= 2.2$.

description: Theoretical study is presented for a spinor Bose-Einstein condensate, whose two components are coupled by copropagating Raman beams with different orbital angular momenta. The investigation is focused on the behavior of the ground state of this condensate, depending on the atom-light coupling strength. By analyzing the ground state, we have identified a number of quantum phases, which reflect the symmetries of the effective Hamiltonian and are characterized by the specific structure of the wave function. In addition to the well-known stripe, polarized and zero-momentum phases, our results show that the system can support phases, whose wave function contains a complex vortex molecule. Such molecule plays an important role in the continuous phase transitions of the system. The predicted behavior of vortex-molecule phases can be examined in cold-atom experiments using currently existing techniques.

The purpose of this study was to describe the perceptions of academic, social and personal preparedness and adjustment in college of students who did and did not participate in an enrichment program(s) intended to help them succeed in college. A descriptive survey was completed voluntarily online by the enrichment group, and respondents were asked to select a peer in their program of study whom s/he believed did not attend a college preparatory enrichment program to complete the survey also. However, only participants who received enrichment completed the survey and took part in the follow-up interview. Descriptive statistics were used to analyze the findings and the original comparisons intended were not able to be made. All participants rated items using a six point scale to indicate how academically, socially, and personally prepared they felt they were for college, and using a four point scale to indicate how satisfied they were with their college. Participants also had opportunities to state what aspects of their enrichment experience were helpful in college and from those participants a subsample who was interviewed stated that they wanted to remain an active part of the program, suggesting such programs are helpful.

description: High-level quantum-chemical calculations are reported at the MP2 and CCSD(T) levels of theory for the equilibrium structure and the harmonic and anharmonic force fields of diacetylene, HCCCCH. The calculations were performed employing Dunning's hierarchy of correlation-consistent basis sets cc-pVXZ, cc-pCVXZ, and cc-pwCVXZ, as well as the ANO2 basis set of Almloef and Taylor. An empirical equilibrium structure based on experimental rotational constants for thirteen isotopic species of diacetylene and computed zero-point vibrational corrections is determined (r_e^emp: rC-H=1.0615 A, rCtripleC=1.2085 A, rC-C = 1.3727 A) and in good agreement with the best theoretical structure (CCSD(T)/cc-pCV5Z: rC-H=1.0617 Angstrom, rCtripleC=1.2083 A, rC-C=1.3737 A). In addition, the computed fundamental vibrational frequencies are compared with the available experimental data and found in satisfactory agreement.

By studying the model near the transition time, in which the system crosses the w=-1 phantom-divide-line, the conditions needed to overcome the coincidence problem is investigated. The phantom model, as a candidate for dark energy, is considered and for two specific examples, the quadratic and exponential phantom potentials, it is shown that it is possible the system crosses the w=-1 line, meanwhile the coincidence problem is alleviated, the two facts that have root in observations.

description: Antihydrogen atoms are produced at CERN in highly excited Rydberg states. However, precision measurements require anti-atoms in ground state. Whereas experiments currently rely on spontaneous emission only, simulations have shown that THz light can be used to stimulate the decay towards ground state and thus increase the number of anti-atoms available for measurements. We review different possibilities at hand to generate light in the THz range required for the purpose of stimulated deexcitation. We demonstrate the effect of a blackbody type light source, which however presents drawbacks for this application including strong photoionization. Further, we report on the first THz transitions in a beam of Rydberg caesium atoms induced by photomixers and conclude with the implications of the results for the antihydrogen case.

description: Moving cameras provide multiple intensity measurements per pixel, yet often semantic segmentation, material recognition, and object recognition do not utilize this information. With basic alignment over several frames of a moving camera sequence, a distribution of intensities over multiple angles is obtained. It is well known from prior work that luminance histograms and the statistics of natural images provide a strong material recognition cue. We utilize per-pixel {\it angular luminance distributions} as a key feature in discriminating the material of the surface. The angle-space sampling in a multiview satellite image sequence is an unstructured sampling of the underlying reflectance function of the material. For real-world materials there is significant intra-class variation that can be managed by building a angular luminance network (AngLNet). This network combines angular reflectance cues from multiple images with spatial cues as input to fully convolutional networks for material segmentation. We demonstrate the increased performance of AngLNet over prior state-of-the-art in material segmentation from satellite imagery.

description: Training new surgeons in spinal surgery is both challenging and costly, often relying on expensive models that concentrate on specific aspects of the procedure. The preparation process for surgical students is lengthy before they gain hands-on experience with actual patients. This research, however, introduces an innovative model crafted to drastically change the surgeon training.This model utilizes nondestructive evaluation techniques to offer real-time feedback during simulated surgeries. Its primary objective is to evaluate and analyze the pressure exerted on the spine throughout the surgical process. By embedding an array of sensors within the model and scrutinizing the collected data, the model can precisely identify the nature and magnitude of pressure applied during the operation. Collaborations with medical experts are integral to establishing safe and optimal pressure thresholds.Simulations are meticulously conducted and compared against empirical measurements to gauge the accuracy and feasibility of diverse sensor types and model designs. Through rigorous exploration, the force-sensing-resistor (FSR) sensor emerges as a promising candidate. Its ease of fabrication and adaptability to the model structure make it particularly favorable.This newly developed spinal cord surgery model offers a cost-effective, straightforward, and efficient platform that has the potential to significantly reduce the time and expense associated with training aspiring surgeons. Its implementation could markedly enhance medical care for patients grappling with spinal cord issues, ultimately elevating the efficacy of treatment methods in this critical domain.

description: We have investigated the role of the 4$f$ moment on the magnetoelectric (ME) effect of orthorhombic $R$MnO$_{3}$ ($R$=rare earth ions). In order to clarify the role of the 4$f$ moment, we prepared three samples: (Eu,Y)MnO$_{3}$ without the 4$f$ moment, TbMnO$_{3}$ with the anisotropic 4$f$ moment, and (Gd,Y)MnO$_{3}$ with the isotropic 4$f$ moment. The ferroelectric behaviors of these samples are different from each other in a zero magnetic field. (Eu,Y)MnO$_{3}$ and (Gd,Y)MnO$_{3}$ show the ferroelectric polarization along the a axis in the ground state, while TbMnO$_{3}$ shows it along the c axis. Such difference may arise from the influence of the anisotropic Tb$^{3+}$ 4$f$ moment. The direction of the ferroelectric polarization of $R$MnO$_{3}$ is determined by the internal magnetic field arising from the 4$f$ moment.

description: A quaternionic version of the Calabi problem on Monge-Ampere equation is introduced. It is a quaternionic Monge-Ampere equation on a compact hypercomplex manifold with an HKT-metric. The equation is non-linear elliptic of second order. For a hypercomplex manifold with holonomy in SL(n;H), uniqueness (up to a constant) of a solution is proven, as well as the zero order a priori estimate. The existence of solution is conjectured, similar to Calabi-Yau theorem. We reformulate this quaternionic equation as a special case of a complex Hessian equation, making sense on any complex manifold.

description: We have investigated orthorhombic $R$MnO$_{3}$ ($R$=(Gd$_{1-y}$Tb$_{y}$)) crystals near the phase boundary between the paraelectric $A$-type-antiferromagnetic (AF) phase (PA) and the ferroelectric transverse-spiral-AF one (FS). The spiral AF structure breaks inversion symmetry and induces the ferroelectric polarization through the inverse Dzyaloshinskii-Moriya (DM) interaction. We have found that the PA-FS phase boundary is located at around 0.15$

description: Energy level quantization (ELQ) is studied to clarify the macroscopic quantum dynamics of the d-wave Josephson junction (JJ). The influences of the nodal quasiparticles of d-wave superconductivity on the damping effect are numerically evaluated on the basis of a phenomenological model. The calculation, based on realistic parameters for a Bi2Sr2CaCu2O8+d (Bi2212) intrinsic JJ, shows that the observation of ELQ is possible when the sweep rate of the bias current exceeds 10 A/sec. High-sweep- rate measurements (121A/sec) performed on a Bi2212 intrinsic JJ result in the appearance of multiple peaks in the switching current distribution suggesting the realization of ELQ in the d-wave JJ.

description: We analyze coherent transport of photons, which propagate in a one-dimensional coupled-resonator waveguide (CRW) and are scattered by a controllable two-level system located inside the CRW. Our approach, which uses discrete coordinates, unifies "low" and "high" energy effective theories for single photon scattering. We show that the controllable two-level system can behave as a quantum switch for the coherent transport of photons. This study may inspire new electro-optical single-photon quantum devices. We also suggest an experimental setup based on superconducting transmission line resonators and qubits

The Effects of a Homework Club Intervention on Math Test Scores for At-Risk Second Graders in a Title I School

Subjects: subject: Homework
subject: At-risk

subject: Education -- Research papers (Graduate)

description: The purpose of this quasi-experimental study, pretest-posttest design, was to determine the effects of supporting math homework completion on the math achievement grades of at-risk second graders in a Title I public school. Students, who were unsuccessful, scoring below 70%, were invited to participate in a homework club as an intervention, conducted by the researcher who was also the classroom teacher. The purpose of the homework club was to decrease students’ chances of becoming at-risk of failing the core subject. Five students were given permission by their parents to participate in the treatment after school homework club group and three students’ parents declined the invitations, the control group. Both groups were given the same measurements: the pretests and posttests from units one and two of the math curriculum, homework assignments, and surveys. Parents of both groups also completed a survey. Participants of the homework club received a modified survey at the end of the study to depict their perceptions about the homework club. Ratings from the surveys suggested that students enjoyed participating in the homework club because they were able to complete their homework assignments, receive help from the teacher, and self-select manipulatives to solve math problems. Additional results from this study indicate there was an increase in the number of math homework assignments completed and in academic achievement when comparing the differences of the pretest and posttest results for units one and two for both groups. However, participants in the homework club demonstrated more academic growth on their unit two math assessment. Further research should be conducted to explore the effects of a homework club as in intervention in other subject areas.
Scales in nuclear matter: Chiral dynamics with pion nucleon form factors

description: A systematic calculation of nuclear matter is performed which includes the long-range correlations between nucleons arising from one- and two-pion exchange. Three-body effects from $2π$-exchange with excitations of virtual $Δ(1232)$-isobars are also taken into account in our diagrammatic calculation of the energy per particle $\bar E(k_f)$. In order to eliminate possible high-momentum components from the interactions we introduce at each pion-baryon vertex a form factor of monopole type. The empirical nuclear matter saturation point, $ρ_0 \simeq 0.16 $fm$^{-3}$, $\bar E_0\simeq -16 $MeV, is well reproduced with a monopole mass of $Λ\simeq 4πf_π\simeq 1.16 $GeV. As in the recent approach based on the universal low-momentum $NN$-potential $V_{\rm low-k}$, the inclusion of three-body effects is crucial in order to achieve saturation of nuclear matter. We demonstrate that the dependence of the pion-exchange contributions to $\bar E(k_f)$ on the ''resolution'' scale $Λ$ can be compensated over a wide range of $Λ$ by counterterms with two ''running'' contact-couplings. As a further application we study the in-medium chiral condensate $(ρ)$ beyond the linear density approximation. For $ρ\leq 1.5 ρ_0$ we find small corrections from the derivative $d \bar E(k_f)/d m_π$, which are stable against variations of the monopole regulator mass $Λ$.
