description: In the present paper we introduce Mobius energy for the embedded graphs and formulate its main properties. This energy is invariant under the action of the group generated by all inversions in three-dimensional real space. We study critical configurations for the angles at vertices of degree less than five, and discuss the techniques of construction of symmetric toric embedded graphs with critical values of Mobius energy.

description: We present experimental evidence of charge exchange between laser-cooled potassium $^{39}$K atoms and calcium $^{40}$Ca$^+$ ions in a hybrid atom-ion trap and give quantitative theoretical explanations for the observations. The $^{39}$K atoms and $^{40}$Ca$^+$ ions are held in a magneto-optical (MOT) and a linear Paul trap, respectively. Fluorescence detection and high resolution time of flight mass spectra for both species are used to determine the remaining number of $^{40}$Ca$^+$ ions, the increasing number of $^{39}$K$^+$ ions, and $^{39}$K number density as functions of time. Simultaneous trap operation is guaranteed by alternating periods of MOT and $^{40}$Ca$^+$ cooling lights, thus avoiding direct ionization of $^{39}$K by the $^{40}$Ca$^+$ cooling light. We show that the K-Ca$^+$ charge-exchange rate coefficient increases linearly from zero with $^{39}$K number density and, surprisingly, the fraction of $^{40}$Ca$^+$ ions in the 4p\,$^2$P$_{1/2}$ electronically-excited state. Combined with our theoretical analysis, we conclude that these data can only be explained by a process that starts with a potassium atom in its electronic ground state and a calcium ion in its excited 4p\,$^2$P$_{1/2}$ state producing ground-state $^{39}$K$^+$ ions and metastable, neutral Ca\,(3d4p$^3$P$_1$) atoms, releasing only 150 cm$^{-1}$ equivalent relative kinetic energy. Charge-exchange between either ground- or excited-state $^{39}$K and ground-state $^{40}$Ca$^+$ is negligibly small as no energetically-favorable product states are available. Our experimental and theoretical rate coefficients of $9\times10^{-10}$ cm$^3$/s are in agreement given the uncertainty budgets.

description: The study attempts to determine the institutional conditions of starting and operating tourist enterprises offering both accommodation and catering services in Lubelskie Voivodship. To establish the actual and desirable facts, a mail survey was sent to sixty-ϐive county ofϐices in Janów, Lublin, Łuków, Opole, Parczew, Puławy, Tomaszów and Włodawa counties. Twenty-six institutions (40%) provided the completed questionnaires. Local governments most often affect investors who consider starting a business, rather than operating a tourist enterprise. Actions supporting businesses that operate in a county are uncommon, but represent a broad spectrum. County governments apply both income and expenditure instruments. Entrepreneurs most often have taken advantage of the interest forgone by the county on late taxes or deferred tax payment terms. The examined counties rarely provide tax relief associated with job creation to the entrepreneurs starting a tourist business. The current state of the analyzed issue is disappointing. It is heartening that many local government institutions recognize the need to improve the situation in the coming years.

description: We address the dynamics induced by collective atomic recoil in a Bose-Einstein condensate in presence of radiation losses and atomic decoherence. In particular, we focus on the linear regime of the lasing mechanism, and analyze the effects of losses and decoherence on the generation of entanglement. The dynamics is that of three bosons, two atomic modes interacting with a single-mode radiation field, coupled with a bath of oscillators. The resulting three-mode dissipative Master equation is solved analytically in terms of the Wigner function. We examine in details the two complementary limits of {\em high-Q cavity} and {\em bad-cavity}, the latter corresponding to the so-called superradiant regime, both in the quasi-classical and quantum regimes. We found that three-mode entanglement as well as two-mode atom-atom and atom-radiation entanglement is generally robust against losses and decoherence,thus making the present system a good candidate for the experimental observation of entanglement in condensate systems. In particular, steady-state entanglement may be obtained both between atoms with opposite momenta and between atoms and photons.

 Distribution. Type locality: Tasmania (Tasman Peninsula, Waterfall Bay, Paterson’s Arch on rock wall, coll. K. Gowlett Holmes, 18 September 1998, holotype SAM E2905).
 Description. The colony is an encrusting sheet with evenly spaced rounded swellings, each with a terminal common cloacal aperture, on the upper surface. A large central common cloacal cavity occupies the surface swellings and canals from the periphery of the cavity extend out amongst the zooids (at oesophageal level). Spicules are present throughout. They are up to 0.09 mm diameter, with short, sharply pointed rays, 11–13 in optical transverse section, the rays are not crowded and their bases are well separated from one another on the central test mass. The ray length / spicule diameter ratio is only about 0.1. Zooids open to the surface through stellate branchial apertures, each with a plug of spicules in the siphon. A short posteriorly orientated atrial siphon arises from the posterior one-third of the dorsal surface and a large circular plate-like lateral organ is just ventral to the base of the atrial siphon. Zooids have large eggs against the dorsum of the post-pyloric gut loop but testis follicles are not present. Larvae are not known.
 Remarks. In the holotype, few details of zooid structure were determined and the species is characterized by its unique spicules with their very short pointed rays. Leptoclinides imperfectus Kott, 1962 has a similar colony, but its spicules have longer rays, and some have truncated or chisel-shaped tips which are not in the present species.

description: A numerically exact dynamical quantum Monte Carlo approach has been developed and applied to transport through a double barrier in a Luttinger liquid with arbitrary transmission. For strong transmission, we find broad Fabry-Perot Coulomb blockade peaks, with a lineshape parametrized by a single parameter, but at sufficiently low temperatures, non-Lorentzian universal lineshapes characteristic of coherent resonant tunneling emerge, even for strong interactions. For weak transmission, our data supports the recently proposed correlated sequential tunneling picture and is consistent with experimental results on intrinsic nanotube dots.

description: In Dec. 2011 PSR B0540-69 experienced a spin-down rate transition (SRT), after which the spin-down power of the pulsar increased by ~36%. About 1000 days after the SRT, the X-ray luminosity of the associated pulsar wind nebula (PWN) was found to brighten by 32+/-8%. After the SRT, the braking index n of PSR B0540-69 changes from n=2.12 to n=0.03 and then keeps this value for about five years before rising to n=0.9 in the following years. We find that most of the current models have difficulties in explaining the measured braking index. One exceptive model of the braking index evolution is the increasing dipole magnetic field of PSR B0540-69. We suggest that the field increase may result from some instabilities within the pulsar core that enhance the poloidal component at the price of toroidal component of the magnetic field. The increasing dipole magnetic field will result in the X-ray brightening of the PWN. We fit the PWN X-ray light curve by two models: one assumes a constant magnetic field within the PWN during the brightening and the other assumes an enhanced magnetic field proportional to the energy density of the PWN. It appears that the two models fit the data well, though the later model seems to fit the data a bit better. This provides marginal observational evidence that magnetic field in the PWN is generated by the termination shock. Future high-quality and high-cadence data are required to draw a solid conclusion.

description: We study how efficiently a $k$-element set $S\subseteq[n]$ can be learned from a uniform superposition $|S\rangle$ of its elements. One can think of $|S\rangle=\sum_{i\in S}|i\rangle/\sqrt{|S|}$ as the quantum version of a uniformly random sample over $S$, as in the classical analysis of the ``coupon collector problem.'' We show that if $k$ is close to $n$, then we can learn $S$ using asymptotically fewer quantum samples than random samples. In particular, if there are $n-k=O(1)$ missing elements then $O(k)$ copies of $|S\rangle$ suffice, in contrast to the $Θ(k\log k)$ random samples needed by a classical coupon collector. On the other hand, if $n-k=Ω(k)$, then $Ω(k\log k)$ quantum samples are~necessary. More generally, we give tight bounds on the number of quantum samples needed for every $k$ and $n$, and we give efficient quantum learning algorithms. We also give tight bounds in the model where we can additionally reflect through $|S\rangle$. Finally, we relate coupon collection to a known example separating proper and improper PAC learning that turns out to show no separation in the quantum case.

A flexible method for estimating luminosity functions via Kernel Density Estimation

description: We propose a flexible method for estimating luminosity functions (LFs) based on kernel density estimation (KDE), the most popular nonparametric density estimation approach developed in modern statistics, to overcome issues surrounding binning of LFs. One challenge in applying KDE to LFs is how to treat the boundary bias problem, since astronomical surveys usually obtain truncated samples predominantly due to the flux-density limits of surveys. We use two solutions, the transformation KDE method ($\hatϕ_{\mathrm{t}}$), and the transformation-reflection KDE method ($\hatϕ_{\mathrm{tr}}$) to reduce the boundary bias. We develop a new likelihood cross-validation criterion for selecting optimal bandwidths, based on which, the posterior probability distribution of bandwidth and transformation parameters for $\hatϕ_{\mathrm{t}}$ and $\hatϕ_{\mathrm{tr}}$ are derived within a Markov chain Monte Carlo (MCMC) sampling procedure. The simulation result shows that $\hatϕ_{\mathrm{t}}$ and $\hatϕ_{\mathrm{tr}}$ perform better than the traditional binned method, especially in the sparse data regime around the flux-limit of a survey or at the bright-end of the LF. To further improve the performance of our KDE methods, we develop the transformation-reflection adaptive KDE approach ($\hatϕ_{\mathrm{tra}}$). Monte Carlo simulations suggest that it has a good stability and reliability in performance, and is around an order of magnitude more accurate than using the binned method. By applying our adaptive KDE method to a quasar sample, we find that it achieves estimates comparable to the rigorous determination by a previous work, while making far fewer assumptions about the LF. The KDE method we develop has the advantages of both parametric and non-parametric methods.

title: Algorithmic Tracking Scheme Analog-to-Digital Converter
Creators: name: Bachmann, Oliver
Publisher: name: UNSPECIFIED

description: Information is an increasingly important factor in today’s world. In particular, the acquisition of physical parameters and their processing are essential for modern applications. Every technical device provides users with ever more precise information about the environment. However, the demand for even more detailed information grows steadily. An Analog-to-Digital Converter (ADC) translates the physical signals into computer-processable representations to provide this information to the consumer’s application. Representing a more detailed version of the environmental information is now limited by the technical realization of this crucial component. As a result, researchers need to establish new ways to meet the demand for growing information. Today’s ADCs usually quantize the information in a one-dimensional way within an equidistant sampling. How- ever, this approach neglects physical signals in two dimensions - in magnitude variations and time variations. While ADCs realize the magnitude quantization with high accuracy, the representation for the resolution in time is usually insufficient. However, a detailed conversion of both dimensions implies a higher information density. Non-uniformly sampled signals represent an alternative, as these retain the relationship to a dynamic variation in the physical signal. As a solution, a completely new method for a high information density conversion based on non-uniform sampling presents the Algorithmic Tracking Scheme ADC. The conceptual basis proposes an ADC that compares the physical input signal to a dynamic reference generated by algorithmic implementations. This proposal leads to fundamental research questions: What is the significance of the reference signal? Which constitution of the reference signal influences the information density? How to realize technical approaches? The analysis of the information density answers these questions. In this context, a mathematical description derives the fundamentals for the study of information density. Possible sampling algorithms are derived from these equations and initialize a dynamic implementation of the ADC topology. As part of the concept evaluation, an FPGA configuration with analog element functionality implements the algorithms. Additionally, the ADC process was transferred and validated on three ASIC prototypes using state-of-the-art technologies and high-performance-computing technologies (65 nm, 65 nm, 28 nm). Both the derived equations and the measurement results mutually confirm each other. Thus, the proposed mathematical equations and design methodology provide a functional development tool for ADC designers.

description: We present an X-ray spectral analysis of 21 low redshift quasars observed with XMM-Newton EPIC. All the sources are Palomar Green quasars with redshifts between 0.05 and 0.4 and have low Galactic absorption along the line-of-sight. A large majority of quasars in the sample (19/21) exhibit a significant soft excess below ~1-1.5keV, whilst two objects (PG1114+445 and IZw1) show a deficit of soft X-ray flux due to the presence of a strong warm absorber. At least half of the objects appear to harbor a warm absorber, as found previously in Seyfert 1 galaxies. We find significant detections of FeKalpha emission lines in at least twelve objects, whilst there is evidence for some broadening of the line profile, compared to the EPIC-pn resolution, in five of these quasars. The determination of the nature of this broadening (e.g., Keplerian motion, a blend of lines, relativistic effects) is not possible with the present data and requires either higher S/N or higher resolution spectra. In seven objects the line is located between 6.7-7keV, corresponding to highly ionized iron, whereas in the other five objects the line energy is consistent with 6.4 keV, i.e. corresponding to near neutral iron. The ionized lines tend to be found in the quasars with the steepest X-ray spectra. We also find a correlation between the continuum power law index and the optical Hbeta width, in both the soft and hard X-ray bands, whereby the steepest X-ray spectra are found in objects with narrow Hbeta widths, which confirms previous ROSAT and ASCA results. The soft and hard band X-ray photon indices are also strongly correlated, i.e. the steepest soft X-ray spectra correspond the steepest hard X-ray spectra.

description: The budget is the basis of local government ϐinancial management. A local unit executes its statutory goals according to the budget. The appropriate preparation of a budget, accounting for the social and economic needs, is the fundamental responsibility of a voyt (an elected county chair). The basic principles and terms of preparation and enactment of a budget as well as its speciϐicity and required elements are included in the public ϐinance bill. Regardless of the statutory requirements, the preparation of a budget should take the principles of planning and administration into account. Retaining a strictly administrative model of financial management is insufficient given challenges faced by local governments. A proper analysis of county financial conditions determines the direction and strategies of county development, based on the budget and using non-budgetary funds.

description: In this paper, we describe a novel framework for digital predistortion (DPD) based linearization of strongly nonlinear millimeter-wave active antenna arrays. Specifically, we formulate a piecewise (PW) closed-loop (CL) DPD solution and low-complexity gradient-adaptive parameter learning algorithms, together with a region partitioning method, that can efficiently handle deep compression of the PA units. The impact of beamsteering on the DPD performance is studied, showing strong beam-dependence, thus necessitating frequent updating of the DPD. In order to facilitate fast adaptation, an inexpensive, non-iterative, pruning algorithm is introduced, which allows to significantly reduce the amount of model coefficients. The proposed methods are validated with extensive over-the-air RF measurements on a 64-element active antenna array transmitter operating at 28 GHz carrier frequency and transmitting a 400 MHz 5G New Radio (NR) standard-compliant orthogonal frequency division multiplexing waveform. The obtained results demonstrate the excellent linearization capabilities of the proposed solution, conforming to the new 5G NR requirements for frequency range 2 (FR2) in terms of both inband waveform quality and out-of-band emissions. The proposed PW-CL DPD is shown to outperform the state-of-the-art PW DPD based on the indirect learning architecture, as well as the classical single-polynomial based DPD solutions in terms of linearization performance and computational complexity by a clear margin.

description: n the latest trends, the entrepreneur intention has been subject to multiple analysis in the academy due to the positive impact on economic activity (Zahra, Wright and Abdelwagad, 2014), in the labor market and as professional development (Vázquez-Burgete, Lanero, Raisiene, & Purificación García, 2012). Universities have developed various activities to promote entrepreneurship in university students of different concentrations. This research evaluated the dimensions of the entrepreneurship profile based on business mentality, managerial / administrative skills, technical skills, personal and family traits, and financial considerations of university students of different concentrations. Also, it analyzed if there is a significant difference in the dimensions of the entrepreneurship profile between Business Administration students and students of other concentrations.The study involved 758 students from different concentrations of a private university in Puerto3Rico. Six hypotheses were tested using a Likert scale questionnaire. The results of the research demonstrated differences between concentrations regarding the entrepreneur profile dimensions and differences, statiscally significant, between the Business Administration students and those of other concentrations.This research contributes to the university’s educational role, by providing empirical data concerning those that have plans, courses and wokshops about entrepreneurship. This, in turn, will have an effect in a well-prepared graduated student in creating their own employment, in a more economically liberal and self-fulfilling society.
Hadronic B Decays Involving Even Parity Charmed Mesons

description: Hadronic B decays containing an parity-even charmed meson in the final state are studied. Specifically we focus on the Cabibbo-allowed decays $\bar B\to D^{**} π(ρ), D^{**}\bar D_s^{(*)}, \bar D^{**}_sD^{(*)}$ and $\bar B_s\to D_s^{**}π(ρ)$, where $D^{**}$ denotes generically a p-wave charmed meson. The $B\to D^{**}$ transition form factors are studied in the improved version of the Isgur-Scora-Grinstein-Wise quark model. We apply heavy quark effective theory and chiral symmetry to study the strong decays of p-wave charmed mesons and determine the magnitude of the $D_1^{1/2}-D_1^{3/2}$ mixing angle. Except the decay to $D_1(2427)^0π^-$ the predictions for $B^-\to D^{**0}π^-$ agree with experiment. The sign of $D_1^{1/2}-D_1^{3/2}$ mixing angle is found to be positive in order to avoid a severe suppression on the production of $D_1(2427)^0π^-$. The interference between color-allowed and color-suppressed tree amplitudes is expected to be destructive in the decay $B^-\to D_1(2427)^0π^-$. Hence, an observation of the ratio $D_1(2427)^0π^-/D_1(2427)^+π^-$ can be used to test the relative signs of various form factors as implied by heavy quark symmetry. Although the predicted $B^-\to D_1(2420)^0ρ^-$ at the level of $3\times 10^{-3}$ exceeds the present upper limit, it leads to the ratio $D_1(2420)ρ^-/D_1(2420)π^-\approx 2.6$ as expected from the factorization approach and from the ratio $f_ρ/f_π\approx 1.6$ . Therefore, it is crucial to have a measurement of this mode to test the factorization hypothesis. For $\bar B\to \bar D_s^{**}D$ decays, it is expected that $\bar D_{s0}^*D\gsim \bar D_{s1}D$ as the decay constants of the multiplet $(D_{s0}^*,D_{s1})$ become the same in the heavy quark limit.

Leptoclinides exiguus

 Leptoclinides exiguus Kott, 2001: 62 and synonymy.
 Distribution. New records: South Australia (St Vincent Gulf, SAM E2906; Kangaroo I., SAM E2907). Previously recorded (see Kott, 2001): South Australia (Gulf St Vincent, Spencer Gulf, Kangaroo I.), Victoria (Phillip Bay, Western Port, Gabo I.).
 Description. Encrusting colonies of variable thickness (to 1 cm) appear to accommodate irregularities in the substratum, while the surface remains relatively even. Irregular grey pigment particles are evenly scattered amongst the spicules in a layer at the level of the branchial siphons beneath a thin superficial spicule-free layer. These pigment particles become more sparse toward the base of the colony. Spicules are present throughout one of the colonies (SAM E2906) but are less crowded in the lower half. In the other specimen (SAM E2907) the basal half of the colony is completely aspiculate. Spicules are to 0.06 mm diameter, stellate, with 11–13 rays in optical transverse section. Ray tips are chisel-shaped. Branchial apertures are along each side of the network of surface depressions over the oesophageal primary cloacal canals.
About 10 stigmata are in the first row of the branchial sac. The gut forms a simple vertical loop. Gonads are present only in one of the newly recorded specimens (SAM E2907). A circle of about six testis follicles has eight coils of the vas deferens around it.
 Remarks. The newly recorded colonies have characteristic zooids (with rather square thoraces and vertical gut loops) arranged along each side of circular oesophageal common cloacal canals as described for this species. Revision of the type material shows the spicules to have 11–13 rays (rather than the 9–11 Kott recorded), and eight coils of the vas deferens have been detected in the holotype (QM G301615) rather than the six Kott reported. One of the newly recorded specimens (SAM E2906) differs from others assigned to this species in having more crowded spicules in the basal half of the colony. They are, however, less crowded in the base than in the upper half of the colony, a difference that would not preclude conspecificity.

description: A nonadiabatic-transition system which exhibits ``quantum chaotic'' behavior [Phys. Rev. E {\bf 63}, 066221 (2001)] is investigated from quasi-classical aspects. Since such a system does not have a naive classical limit, we take the mapping approach by Stock and Thoss [Phys. Rev. Lett. {\bf 78}, 578 (1997)] to represent the quasi-classical dynamics of the system. We numerically show that there is a sound correspondence between the quantum chaos and classical chaos for the system.

Response maxima in time-modulated turbulence: Direct Numerical Simulations

description: The response of turbulent flow to time-modulated forcing is studied by direct numerical simulations of the Navier-Stokes equations. The large-scale forcing is modulated via periodic energy input variations at frequency $ω$. The response is maximal for frequencies in the range of the inverse of the large eddy turnover time, confirming the mean-field predictions of von der Heydt, Grossmann and Lohse (Phys. Rev. E 67, 046308 (2003)). In accordance with the theory the response maximum shows only a small dependence on the Reynolds number and is also quite insensitive to the particular flow-quantity that is monitored, e.g., kinetic energy, dissipation-rate, or Taylor-Reynolds number. At sufficiently high frequencies the amplitude of the kinetic energy response decreases as $1/ω$. For frequencies beyond the range of maximal response, a significant change in phase-shift relative to the time-modulated forcing is observed.

description: In this comment to [S. Lenjer, O. F. Schirmer, H. Hesse, and Th. W. Kool, Phys. Rev. B {\bf 66}, 165106 (2002)] we discuss the electronic structure of oxygen vacancies in perovskites. First principles computations are in favour of rather deep levels in these vacancies, and Lenjer et al suggest that the electrons' interaction energy is negative, but data on electroconductivity are against.

A new parton model for the soft interactions at high energies: the Odderon

description: In this paper we discuss the Odderon contribution in our model[19] that gives a fairly good description of $σ_{\rm tot}$ $σ_{\rm el}$and $B_{\rm el}$ for proton-proton scattering. We show that the shadowing corrections are large, and induce considerable dependence on energy for the Odderon contribution, which in perturbative QCD does not depend on energy. This energy dependence is in agreement with the experimental data for $ρ= {\rm Re}/{\rm Im}$, assuming that the Odderon gives a contribution of about 1 mb at W = 7 TeV. This differs greatly with our estimates for a CGC based model. We reproduce the main features of the $ t$ -dependence that are measured experimentally: the slope of the elastic cross section at small $t$, the existence of the minima in $t$-dependence which is located at $|t|_{min}$ = 0.52 GeV 2 at W= 7 TeV; and the behaviour of the elastic cross section at $ |t| > |t|_{min}$.The real part of the elastic amplitude turns out to be much smaller than the experimental one. Consequently, to achieve a description of the data, it is necessary to add an odderon contribution.

Whole building life cycle assessment : Neville Scarfe Building
Creators: name: Mahiban, Aaron
Publisher: name: The University of British Columbia
Year: 2014

description: This report details a life cycle assessment conducted for the Neville Scarfe building at the University of British Columbia. The portion of the building studied was built in 1961 and is a concrete building with suspended slab floors throughout. The main function of the building is classroom oriented space, however it also includes a staff lounge, a student lounge and a large lecture theater. The material takeoffs for this study were conducted using OnCenter’s Onscreen Takeoff program. Relevant drawings for the building were imported into Onscreen Takeoff as PDF files, to be used for measuring specific dimensions. Once the quantity takeoffs were completed, the amount of each material was entered into Athena’s Impact Estimator software. Referencing an LCI database, this program gave a summary of a number of environmental impacts embodied within the manufacturing and construction of the Scarfe building. The total primary energy required for the construction of the building was 192.6 Mega Joules per square foot of academic building space. It was also determined that the building’s concrete content played the largest role in its environmental impacts. By increasing the volume of concrete by 10%, an average increase of 6% for all measured impacts was observed. Furthermore, it was determined that by bringing the Scarfe building’s insulation up to current standards, the energy savings would surpass the upgrade’s embodied energy in less than two years. This study found that while the Scarfe building was built to the standard of the day, it falls far below the efficiency levels of modern buildings. The full goal and scope, methodology, results and conclusions of the study can be found in the subsequent sections of this report.

description: We respond to the paper by De Marchi, Paresce, Straniero and Moroni (2003) on the white dwarf cooling age of M4. The authors question the data analysis and interpretation that led to the conclusions in Hansen et al. (2002). In their paper, De Marchi et al. are unable to obtain photometry as deep as ours from the same data set and therefore assert that only a lower limit to the white dwarf cooling age for this cluster of approximately 9 Gyr can be obtained. In this short contribution we show that shortcomings in the data analysis and reduction techniques of De Marchi et al. are responsible for their inability to reach the photometry limits that our study reports. In a forthcoming paper in which the complete techniques for age determination with white dwarfs are laid out, we demonstrate that their method of fitting the luminosity function gives a spuriously low white dwarf cooling age.

description: Purpose: The purpose of this study is to examine the impact of an intervention in which childcare providers (CCPs) are coached to support toddlers’ gesture use during every day classroom routines.Method: This study uses a multiple-baseline across strategies single-case experimental design to examine the impact of a coaching intervention on three CCPs’ use of communication strategies with toddlers experiencing early childhood poverty. The CCPs were coached with a systematic framework called Setting the Stage, Observation and Opportunities to Embed, Problem-solving and Planning, Reflection and Review as they learned to implement three strategies to support toddlers’ gesture use—modeling gestures with a short phrase, opportunities to gesture, and responding/expanding child gestures. CCPs were coached during book sharing and another classroom routine of their choice. Social validity data on the coaching approach and on the intervention strategies were gathered from postintervention interviews.Results: The visual analysis and nonoverlap of all pairs’ effect size indicates that the coaching intervention had a functional relation with CCPs’ use of modeling gestures and responding/expanding gestures during book sharing, play, and circle time. Social validity data indicate that CCPs found the coaching framework supportive of their learning and feelings of self-efficacy, and that the intervention strategies supported their toddlers’ communication.Conclusions: The coaching framework was used to increase CCP strategy use during everyday classroom routines with toddlers. CCPs endorsed the coaching approach and the intervention strategies. This study adds to the literature supporting efforts to enhance children’s earliest language learning environments.

description: The simplest quantum generalization of the six-vertex model describes fluctuations of the order parameter of the d-density wave (DDW), believed to compete with superconductivity in the high-Tc superconductors. The ground state of this model undergoes a first order transition from the DDW phase to a resonating plaquette phase as the quantum fluctuations are increased, which is explored with the help of quantum Monte Carlo simulations and analytic considerations involving the n-vector (n=2) model with cubic anisotropy. In addition to finding a new quantum state, we show that the DDW is robust against a class of quantum fluctuations of its order parameter. The inferred finite temperature phase diagram contains unsuspected multicritical points.
