description: The purpose of this study was to evaluate whether supplemental instruction and online homework can improve student performance and understanding in a first-semester calculus course at a large urban four-year college. The study examined the metacognitive and study skills and posttest scores of students. The study also focused on students’ and instructor’s perception and experiences of supplemental instruction and online homework using WebAssign.
      The study used a modified version of the Motivated Strategies for Learning Questionnaire (MSLQ) to reveal any significant differences in metacognitive and study strategies between students in a class with supplemental instruction/online homework and students in a traditional class. Students’ scores on their final examination were analyzed to reveal the effect of mathematical achievement between the control and experimental groups. Surveys and interviews were utilized to provide anecdotal evidence as to the overall effectiveness of the online homework management system and supplemental instruction.
      Results of the study showed no substantial difference between the control group and the experimental group in seven out of eight sub-scales of metacognitive and study strategies: metacognitive self-regulation, time and study environment, effort regulation, help seeking, rehearsal, organization, and critical thinking. But, students with supplemental instruction/online homework showed a higher level of elaboration learning strategies. The interaction of pretest and type of class (traditional or treatment) did not have a significant effect on students’ posttest score. There was no substantial effect of pretest on posttest, but the treatment influenced students’ posttest score. Students’ gender, race, class level, or the number of courses they registered for were insignificant predictors of their posttest scores. The instructor and students agreed that time spent in supplemental instruction sessions and on WebAssign were worthwhile and beneficial. They believed supplemental instruction and online homework using WebAssign may have influenced students’ understanding and performance in the course.

description: We present evidence that anomalous transport in the classical standard map results in strong enhancement of fluctuations in the localization length of quasienergy states in the corresponding quantum dynamics. This generic effect occurs even far from the semiclassical limit and reflects the interplay of local and global quantum suppression mechanisms of classically chaotic dynamics. Possible experimental scenarios are also discussed.

description: We give a Morita equivalence theorem for so-called cyclotomic quotients of affine Hecke algebras of type B and D, in the spirit of a classical result of Dipper-Mathas in type A for Ariki-Koike algebras. As a consequence, the representation theory of affine Hecke algebras of type B and D reduces to the study of their cyclotomic quotients with eigenvalues in a single orbit under multiplication by $q^2$ and inversion. The main step in the proof consists in a decomposition theorem for generalisations of quiver Hecke algebras that appeared recently in the study of affine Hecke algebras of type B and D. This theorem reduces the general situation of a disconnected quiver with involution to a simpler setting. To be able to treat types B and D at the same time we unify the different definitions of generalisations of quiver Hecke algebra for type B that exist in the literature.

description: Workshop abstract Are you establishing and integrating EOSC activities within your country? Do you need more support and opportunities to swap experiences on how embark on an EOSC action plan and how to reach out effectively to research communities about EOSC services? EOSC is gathering a huge momentum, and how this new research support network is established at national level is now at a critical stage, aspects of which are ongoing at a variety of implementation levels in some member states. While activities are different in each country, they could benefit from and be supported by alignment and good practice exchange. This workshop initiated by OpenAIRE, EOSC hub, and RDA-Europe will explore, with the support of the recently funded EOSCsecretariat.eu project, two areas of implementing EOSC at national level: Establishing national action plans and working with research groups and libraries to raise awareness about EOSC. In particular the workshop will touch on how to set up national action plans, set priorities especially at governance level, how to establish coordinated commitment from key stakeholders and to develop value added support and commitments for local infrastructure within the EOSC vision. Another aspect will be that of serving local research groups and how to target specific EOSC services to them, which is a challenging part of EOSC implementation. This session will be structured in a way that will showcase regional examples of EOSC implementation and good practice. The breakout sessions will be grouped at a regional level in order to identify common threads. This workshop will also provide a perfect setting to meet and network with national counterparts and help prepare and pave the way to set up EOSC and a better understanding of how EOSC works at the national level.

description: Recovery from DNA damage is critical for cell survival. However, serious damage cannot be repaired, leading to cell death for prevention of abnormal cell growth. Previously, we demonstrated that 4N-DNA accumulates via the initiation of an abnormal interphase without cytokinesis and that re-replication occurs during a prolonged recovery period in the presence of severe DNA damage in mitotic cells. Mitotic phosphorylated Plk1 is typically degraded during mitotic exit. However, Plk1 has unusually found to be dephosphorylated in mitotic slippage without cytokinesis during recovery from mitotic DNA damage. Here, we investigated how Plk1 dephosphorylation is established during recovery from mitotic DNA damage. Mitotic DNA damage activated ATM and Chk1/2 and repressed Cdk1 and Greatwall protein kinase, followed by PP2A activation through the dissociation of ENSA and PP2A-B55. Interaction between Plk1 and PP2A-B55α or PP2A-B55δ was strongly induced during recovery from mitotic DNA damage. Moreover, the depletion of PP2A-B55α and/or PP2A-B55δ by siRNA transfection led to the recovery of Plk1 phosphorylation and progression of the cell cycle into the G1 phase. Therefore, to adapt to severe DNA damage, the activated Greatwall/ENSA signaling pathway was repressed by ATM/Chk1/2, even in mitotic cells. Activation of the PP2A-B55 holoenzyme complex induced the dephosphorylation of Plk1 and Cdk1, and finally, mitotic slippage occurred without normal chromosome segregation and cytokinesis.
Different instances of time as different quantum modes: quantum states across space-time for continuous variables

description: Space-time is one of the most essential, yet most mysterious concepts in physics. In quantum mechanics it is common to understand time as a marker of instances of evolution and define states around all the space but at one time; while in general relativity space-time is taken as a combinator, curved around mass. Here we present a unified approach on both space and time in quantum theory, and build quantum states across spacetime instead of only on spatial slices. We no longer distinguish measurements on the same system at different times with measurements on different systems at one time and construct spacetime states upon these measurement statistics. As a first step towards non-relativistic quantum field theory, we consider how to approach this in the continuous-variable multi-mode regime. We propose six possible definitions for spacetime states in continuous variables, based on four different measurement processes: quadratures, displaced parity operators, position measurements and weak measurements. The basic idea is to treat different instances of time as different quantum modes. They are motivated by the pseudo-density matrix formulation among indefinite causal structures and the path integral formalism. We show that these definitions lead to desirable properties, and raise the differences and similarities between spatial and temporal correlations. An experimental proposal for tomography is presented, construing the operational meaning of the spacetime states.

description: Forced advection of passive tracer, $θ$, in nonlinear relaxational medium by large scale (Batchelor problem) incompressible velocity field at scales less than the correlation length of the flow and larger than the diffusion scale is considered. Effective theory explaining small scale scalar fluctuations is proven to be linear, asymptotic free (downscales from the scale of the pumping) and universal. Only three parameters are required to decribe exhaustively the small scale statistics of scalar difference: two velocity-dependent ones, average and dispersion ($\barλ$ and $Δ$ respectively) of the exponential stretching rate of a trial line element, and $α$, standing for average rate of linear damping of small scale scalar fluctuations. $α$ is an explicit functional of potential chracterized medium nonlinearity and amplitude of $θ^{2}$ flux pumped into the system. Structure functions show an extremely anomalous, intermittent behavior: $ \sim r^{ξ_{q}}, ξ_{q} = \min {q,\sqrt{[ \frac{\barλ}Δ] ^{2} + \frac{2αq}Δ} - \frac{\barλ}Δ}$. No dissipative anomaly is found in the problem.

description: A putative powerlaw range of the probability density of velocity gradient in high-Reynolds-number forced Burgers turbulence is studied. In the absence of information about shock locations, elementary conservation and stationarity relations imply that the exponent $-α$ in this range satisfies $α\ge3$, if dissipation within the powerlaw range is due to isolated shocks. A generalized model of shock birth and growth implies $α=7/2$ if initial data and forcing are spatially homogeneous and obey Gaussian statistics. Arbitrary values $α\ge3$ can be realized by suitably constructed homogeneous, non-Gaussian initial data and forcing.

The Effectiveness of Using Incentives in Spatial Zones to Promote Renewable Energy: A Case Study: New York City's Solar Empowerment Zone Program

Renewable energy sources--Planning

description: Urban planning utilizes regulations and incentives such as FAR bonuses to spatially target changes in the built form. This concept can be employed formally through the zoning resolution or more informally through special economic development districts. Recently, however, this same concept has also been employed to promote renewable energy, by targeting limited resources in locations where they might be most cost-effective. While this idea- in ways an antecedent for formal renewable energy districts or zones- is innovative, it remains to be seen if targeting incentives spatially in such a manner is effective in terms of actual renewable energy deployment. To analyze this issue, this paper explores New York City's recent Solar Empowerment Zone Program. Its purpose is twofold: to both analyze whether the program is effective and, on a larger level, to determine if spatially targeting incentives and resources such as education and streamlined permitting can effectively promote solar energy. To accomplish this, both a GIS and statistical analysis were conducted to ascertain whether the number of planned and existing solar installations within the zones were different from those outside the zones. Additionally, approximately 20 stakeholder interviews were conducted to determine what aspects of the zones were working well, what needed further improvement, and what over-arching lessons could be offered regarding using zoning to promote solar energy. The main findings were that education within the zones was not as effective as hoped in terms of increasing solar deployment and that the concept of solar zones should only be pursued when the correct balance of stakeholder interests exists. Finally, incentives within the zones need to be different enough from locations outside the zones if they are to drive the decision making process.

description: The theory of scarring of eigenfunctions of classically chaotic systems by short periodic orbits is extended in several ways. The influence of short-time linear recurrences on correlations and fluctuations at long times is emphasized. We include the contribution to scarring of nonlinear recurrences associated with homoclinic orbits, and treat the different scenarios of random and nonrandom long-time recurrences. The importance of the local classical structure around the periodic orbit is emphasized, and it is shown for an optimal choice of test basis in phase space, scars must persist in the semiclassical limit. The crucial role of symmetry is also discussed, which together with the nonlinear recurrences gives a much improved account of the actual strength of scars for given classical orbits and in individual wavefunctions. Quantitative measures of scarring are provided and comparisons are made with numerical data.

The Effects of Attentional Focus on Novice and Expert Dynamic Indoor Rowing Performance

description: Background. Motor skill learning and performance are optimized when individuals direct their attention externally towards the desired effect. Improvements include increased force production and improved coordination, determinants that also significantly influence rowing performance. However, no consensus surrounding an “ideal” rowing technique and these determinants exists. Attentional focus cues may not only improve rowing performance, but also enhance understanding of factors affecting force production. Aims. Two studies evaluated the efficacy of attentional focus on 1) distance rowed by novice participants; 2) power and peak force generated by novice participants; 3) distance rowed by novice & expert participants 4) force production measures of power, peak force, peak force max, and joules, as well as force signature measures of stroke length, peak force position, mean to peak force ratio, and variability in novice and expert participants; 5) rowing outcomes while controlling for participant stature; and 6) coordination of the legs and trunk during dynamic indoor rowing. Methods. Thirty novice and nineteen experts completed three 45 second long trials on a dynamic indoor rower (RP3), with the goal of rowing as fast as possible between 24 and 26 strokes per minute. Prior to each trial, participants were given attentional focus cues: internal - “As you row, focus on pushing with your legs”; external - “As you row, focus on creating pressure on the handle”; and a baseline condition, where no cue was provided. All three cues were counter-balanced. Results. There were no effects of attentional focus on outcomes, with the exception of increased stroke length for expert participants while rowing with an external focus. Significant effects were found for gender, expertise, and stature. Variability distinguished novices from experts. Participants reported difficulty managing their ability to row as fast as possible, maintain a stroke rate of 24 to 26, and focus on the cue. Conclusion. As the first study to evaluate the efficacy of attentional focus on force production in rowing, results indicated limited support for an external focus of attention. Individual, task, and environmental factors may have influenced rowing outcomes. Further investigation evaluating attentional focus and rowing that accounts for these factors is suggested.

The latter problem is transformed into an auxiliary spectral problem which corresponds to the diagonalization of the integrals of motion of the BCS model. A generating functional whose quasi classical expansion leads to the constants of motion of the BCS model and in particular the Hamiltonian, is identified.

description: Fragile quantum effects such as single electron charging in quantum dots or macroscopic coherent tunneling in superconducting junctions are the basis of modern quantum technologies. These phenomena can only be observed in devices where the characteristic spacing between energy levels exceeds the thermal energy, $k_\textrm{B}T$, demanding effective refrigeration techniques for nanoscale electronic devices. Commercially available dilution refrigerators have enabled typical electron temperatures in the $10$ to $100\,$mK regime, however indirect cooling of nanodevices becomes inefficient due to stray radiofrequency heating and weak thermal coupling of electrons to the device substrate. Here we report on passing the millikelvin barrier for a nanoelectronic device. Using a combination of on-chip and off-chip nuclear refrigeration, we reach an ultimate electron temperature of $T_\textrm{e}=421\pm35\,μ$K and a hold time exceeding $85\,$hours below $700\,μ$K measured by a self-calibrated Coulomb-blockade thermometer.

description: Velocity dependent forces varying as $k(\hat{r}/r)(1 - μ\dot{r}^2 + γr \ddot{r})$ (such as Weber force), here called Weber-like forces, are examined from the point of view of energy conservation and it is proved that they are conservative if and only if $γ=2μ$. As a consequence, it is shown that gravitational theories employing Weber-like forces cannot be conservative and also yield both the precession of the perihelion of Mercury as well as the gravitational deflection of light.

description: Dialogic argument activities have been shown to facilitate the development of argumentative writing in young adolescents. The present study investigates the extent to which collaborative writing has a further facilitative effect, serving as a bridge between the dialogic and individual writing contexts.  Over the course of one school year, a total of 54 students in two low-performing 7th grade classes participated in a twice-weekly dialogic argument curriculum of known effectiveness that included various kinds of dialogic activities addressing a sequence of four topics an individual essay as the culminating activity for each of the topics.  In a quasi-experimental design, one class was randomly chosen as an experimental group and the other as a comparison group. The participation of the two classes in the curriculum was identical except that in one class students had an additional activity toward the end of each 15-session topic unit, during which they were asked to collaborate with a classmate who held the opposing view on the topic and produce a jointly written essay. The comparison group also wrote an interim essay but did so individually rather than collaboratively.
      Compared to students who only wrote individually, collaborative writers performed better on their subsequent final individual essays on the topic. They anticipated the arguments of the other side better, and countered them using an integrative argumentation structure more often. Further, they repeated ideas less often and had more unique idea units in their essays.
      To explore the collaborative processes possibly underlying the differences between the groups, analyses of digital voice recordings from the collaborative writing activity were examined. In addition, the transfer of ideas from the collaborative to subsequent individual essays was examined.  The recordings of verbal dialogue between the pair engaged in collaborative essay writing show an increase over the year in metacognitive dialogue pertaining to their task. Furthermore, in their subsequent individually-written essays, students utilized and built on ideas presented by their partner. Most notable was inclusion in the individual essay of arguments and evidence supporting the opposing partner’s position, particularly when the ideas presented supported the opposite side of the argument. Both of these developments support the view that collaborative writing aids in the development of an argumentative mindset that transforms inter-individual dialogue into intra-individual reflection.

description: The structure of spiral waves is investigated in super-excitable reaction-diffusion systems where the local dynamics exhibits multi-looped phase space trajectories. It is shown that such systems support stable spiral waves with broken symmetry and complex temporal dynamics. The main structural features of such waves, synchronization defect lines, are demonstrated to be similar to those of spiral waves in systems with complex-oscillatory dynamics.

description: In three experiments, I tested the effects of the conditioned reinforcement for reading (R+Reading) on reading comprehension with 5th graders. In Experiment 1, I conducted a series of statistical analyses with data from 18 participants for one year. I administered 4 pre/post measurements for reading repertoires which included: 1) state-wide assessments, 2) district-wide assessments, 3) 20 min observational probes, and 4) preference probes. I utilized the standardized testing measurements to establish grade-level reading repertoires, while the additional two probes measured the reinforcement value of reading. Observational data were recorded in 10s whole-intervals; participants who were observed to read for 96 of the 120 intervals (80%) were considered to have R+Reading. The results demonstrated that R+Reading is significantly correlated with reading assessment outcomes. In Experiment 2, I implemented a two-year cross-sectional design with 33 participants, where I expanded the previous research to include probe trials for conditioned seeing (CS) and derivational responding (DR). Results of Experiment 2 indicated that increases in standardized testing scores were significantly correlated with R+Reading, and that CS and DR were prerequisite repertoires for the acquisition of R+Reading. In Experiment 3, I tested the effects of the peer-yoked contingency procedure on the reinforcement value of reading and assessed if increases in the reinforcement value of reading functioned to increase reading comprehension. Results indicated that increases in the reinforcement value of reading also was related to increases in reading comprehension.

description: We analyze the impact of recent solar, atmospheric and reactor data in the determination of the neutrino oscillation parameters, taking into account that both the solar nu_e and the atmospheric nu_mu may convert to a mixture of active and sterile neutrinos. We use the most recent global solar neutrino data, including the 1496-day Super-K neutrino data sample, and we investigate in detail the impact of the SNO neutral current, spectral and day/night data by performing also an analysis using only the charged current rate from SNO. The implications of the first 145.1 days of KamLAND data on the determination of the solar neutrino parameters are also discussed in detail. We confirm the clear preference of solar+reactor data for the pure active LMA-MSW solution of the solar neutrino problem, and obtain that the LOW, VAC, SMA and Just-So^2 solutions are disfavored with a Delta_chi^2 = 22, 22, 36, 44, respectively. Furthermore, we find that the global solar data constrains the admixture of a sterile neutrino to be less than 43% at 99% CL. By performing an improved fit of the atmospheric data, we also update the corresponding regions of oscillation parameters. We find that the recent atmospheric Super-K (1489-day) and MACRO data have a strong impact on constraining a sterile component in atmospheric oscillations: if the nu_mu is restricted to the atmospheric mass states only a sterile admixture of 16% is allowed at 99% CL, while a bound of 35% is obtained in the unconstrained case. Pure sterile oscillations are disfavored with a Delta_chi^2 = 34.6 compared to the pure active case.

description: We examine the effect of short unstable periodic orbits on wavefunction statistics in a classically chaotic system, and find that the tail of the wavefunction intensity distribution in phase space is dominated by scarring associated with the least unstable periodic orbits. In an ensemble average over systems with classical orbits of different instabilities, a power law tail is found, in sharp contrast to the exponential prediction of random matrix theory. The calculations are compared with numerical data and quantitative agreement is obtained

description: Dark Matter and Dark Energy are accepted as legitimate constituents of our Universe. In this talk I will review the numerous observational evidences supporting the existence of the dark side of the Universe, which is why cosmologists claim shamelessly that 95% of the Universe is made of something they do not know the nature of. I will then discuss many of the hypothetical physical origins for Dark Matter and Dark Energy and outline the major research directions now undertaken in order to test the various possible ideas.

description: Small planets around low-mass stars often show orbital periods in a range that corresponds to the temperate zones of their host stars which are therefore of prime interest for planet searches. Surface phenomena such as spots and faculae create periodic signals in radial velocities and in observational activity tracers in the same range, so they can mimic or hide true planetary signals. We aim to detect Doppler signals corresponding to planetary companions, determine their most probable orbital configurations, and understand the stellar activity and its impact on different datasets. We analyze 22 years of data of the M1.5V-type star Gl49 (BD+61 195) including HARPS-N and CARMENES spectrographs, complemented by APT2 and SNO photometry. Activity indices are calculated from the observed spectra, and all datasets are analyzed with periodograms and noise models. We investigate how the variation of stellar activity imprints on our datasets. We further test the origin of the signals and investigate phase shifts between the different sets. To search for the best-fit model we maximize the likelihood function in a Markov Chain Monte Carlo approach. As a result of this study, we are able to detect the super-Earth Gl49b with a minimum mass of 5.6 Ms. It orbits its host star with a period of 13.85d at a semi-major axis of 0.090 au and we calculate an equilibrium temperature of 350 K and a transit probability of 2.0%. The contribution from the spot-dominated host star to the different datasets is complex, and includes signals from the stellar rotation at 18.86d, evolutionary time-scales of activity phenomena at 40-80d, and a long-term variation of at least four years.

description: Asymmetric reduction studies of heteroaryl ketones, including phenyl(pyridin-2-yl)methanone in enantioselective form with biocatalysts are very few, and chiral heteroaryl alcohols have been synthesized generally in the small scale. In this study, seven bacterial strains have been used to produce the (S)-phenyl(pyridin-2-yl)methanol in high enantiomeric excess and yield. Among the tested strains, Lactobacillus paracasei BD101, was found to be the best biocatalyst for the reducing phenyl(pyridin-2-yl)methanone to the (S)-phenyl(pyridin-2-yl)methanol at gram scale. The asymmetric bioreduction conditions were systematically optimized using L. paracasei BD101, which demonstrated excellent enantioselectivity and high level of conversion for the bioreduction reaction. (S)-phenyl(pyridin-2-yl)methanol, which is an analgesic, was produced enantiomerically pure form in the first time on gram scale using a biocatalyst. In total, 5.857 g of (S)-phenyl(pyridin-2-yl)methanol in enantiomerically pure form (>99% enantiomeric excess) was obtained in 52 h with 93% yield using whole cells of L. paracasei BD101. Enantiomerically pure (S)-phenyl (pyridin-2-yl)methanol, which is an analgesic, was first produced in the gram scale using a biocatalyst with excellent ee (>99%) and yield (93%).
