description: Pyramid wavefront sensors have shown their ability to achieve ultimate performances in
terms of usage of starlight photons. Several of these advantages, however, do relay on the fact that the
starlight is focused onto the pyramid pin after being properly corrected. While conventional adaptive
optics systems (including multi conjugated ones) automatically imply such a feature this is not true for
Multi Objects or non conventional Multi Conjugated AO systems, or more in general for the ones where
the compensated area is somehow different from the area searched for references. We have developed the
concept of locally closed loop systems in a compact way along with various approaches to metrologically
measure the wavefront with enough absolute accuracy, in contrast with the accuracy to vanish the residual
in the conventional use of wavefront sensors. We show an optomechanical study conceived for the E-ELT
and a choice of existing components in order to achieve the goal of detailed wavefront sensing with high
dynamic range on the faintest references where a pyramid sensor can achieve significant results.

In this note we prove that for any prime $p\ge 7$, $$ \sum_{k=1}^{p-1}\frac{H_k^2}{k^2} \equiv4/5pB_{p-5}\pmod{p^2}, $$ which confirms the conjecture recently proposed by Z. W. Sun. Furthermore, we also prove two similar congruences modulo $p^2$.

description: The SPHERE instrument is the 2nd generation instrument dedicated to exoplanet direct imaging
and characterization. The extremely high imaging performance required by these observation mode calls for a
high performance AO system. Particularly, this system has to provide a wavefront corrected from turbulent and
internal defects. We present here the experimental results for the complete focal-plane calibration procedure of
the SPHERE instrument internal defects. An optimized phase diversity method is applied allowing to deal with
model uncertainties in the image formation (noise, residual background, amplitude fluctuation, sampling factor,
defocalisation distance, object size and SH-model for reference slope modifications) The full procedure includes
both Non-Common Path Aberrations (NCPA) compensation at the level of the coronagraphic mask using the
eXtreme AO system itself (by the mean of modification of the filtered SHWFS reference slopes during close loop
operations), but also additional measurements of IRDIS differential optical path aberrations for post processing of
dual-band images. We validate the algorithm and the pre-compensation procedure using data obtained during the
first eXtreme AO bench (SAXO) integration and tests. We also applied the Diversity tool on stand-alone IRDIS
data obtained at LAM during its local integration. In both cases, we demonstrate the robustness and the ultimate
performance (nanometric precision of the residual quasi-static pattern) of the phase diversity approach which will
allow us to obtain nanometric accuracy on the final SPHERE system.

description: Phase diversity is a commonly used technique to retrieve the wavefront at the focal plane. The usual
algorithm involves two or more images of the same target with known phase changes like defocus. It has been
shown to be very efficient at measuring on-axis the non-common path aberrations of classical AO systems. In
this paper, we present an evolution of this algorithm towards tomographic measurements. This novel technique is
dedicated to wide-field AO systems, allowing phase retrieval on multiple layers, conjugated at various altitudes.
While the general grounds are very similar to classical phase diversity, the tomographic algorithm involves two
or more images with known phase changes of several targets dispatched over the entire field of view. We additionally
propose two versions for this algorithm: an image-based and a Fourier-based both leading to comparable
results. We finally present the results obtained on simulated data as well as on real data obtained on GeMS: the
Gemini MCAO system on which this algorithm has been used to estimate and compensate for non common path
aberrations.

A Dip after the Early Emission of Super-Luminous Supernovae: A Signature of Shock Breakout within Dense Circumstellar Media

description: The origin of super-luminous supernovae (SLSNe), especially the source of their huge luminosities, has not been clarified yet. While a strong interaction between SN ejecta and dense circumstellar media (CSM) is a leading scenario, alternative models have been proposed. In this Letter, we suggest new diagnostics to discriminate the strong SN-CSM interaction scenario from the others: a decline in the luminosity ('dip') before the main peak of the light curve. This dip is an unavoidable consequence of having a dense CSM within which the shock breakout occurs. If a dense CSM shell is located far at large radii from the progenitor inside, it takes time for the SN ejecta to reach it and the early light curve can be powered by the SN ejecta before the collision. Once the SN ejecta collides with the dense CSM, the electron density and thus the Thomson scattering opacity suddenly increase. Photons become unable to go out of the shock even if there is a source of emission inside, which results in the dip in the light curve. This dip is a solid prediction from the strong interaction scenario irrespective of a power source for the early emission. Eventually the forward shock breaks out from within the dense CSM, and the luminosity increases by the continuous strong SN-CSM interaction, resulting in an SLSN. The possible dip observed in the hydrogen-poor SLSN, 2006oz, could be the first example of this signature and give support to the SN-CSM interaction as the power source of SLSN 2006oz.

description: During the LBT FLAO commissioning, the Pyramid Wave-Front Sensor demonstrated on sky its
potential as component of a NGS SCAO system. These results confirmed the expected P-WFS sensitivity in
presence of a point-like guide source. The performances of the P-WFS using an extended object as reference
in astronomical applications have not yet been deeply investigated. In this work we present some preliminary
investigation on this topic. We will show here: a first experimental result on the sensitivity obtained in laboratory
with the LBT FLAO system #2 using extended reference sources of diameter (projected on-sky) up to 1.6" and
some consideration on the effect of a vertical extension of the source as in the case of a Na LGS.

description: A decade after the first achievement into the improved capabilities in sensing by the pyramid wavefront sensor and from the outlining of novel classes of Multi Conjugated Adaptive Optics experimental verification of such approaches has been vastly proved by results from MAD onboard VLT and from FLAO onboard LBT. Refinement and extensions of these techniques promises to achieve similar goals within references scattered in a Field of View much larger than the one being compensated, an approach only marginally exploited in the so-called Multiple Field of View approach while the adoption of virtual DMs would allow a much deeper exploitation of such possibilities. As in the meantime the diameter of the largest project shortened somehow it is time to gather all these concept, to assemble -possibly- in an efficient way in order to continue to pursue the goal of achieving diffraction limited imagery at a level concorrential with what is being promised by artificial references, by the usage of solely natural guide stars. The resulting approach is a robust one (as it is not incompatible with Laser generated beacons) and can be implemented into existing optical design of the current extremely large telescopes under development.

description: We study the decay of superflow of a one-dimensional (1D) superfluid in the presence of a periodic potential. In 1D, superflow at zero temperature can decay via quantum nucleation of phase slips even when the flow velocity is much smaller than the critical velocity predicted by mean-field theories. Applying the instanton method to the O(2) quantum rotor model, we calculate the nucleation rate of quantum phase slips $Γ$. When the flow momentum $p$ is small, we find that the nucleation rate per unit length increases algebraically with $p$ as $Γ/L \propto p^{2K-2}$, where $L$ is the system size and $K$ is the Tomonaga-Luttinger parameter. Based on the relation between the nucleation rate and the quantum superfluid-insulator transition, we present a unified explanation on the scaling formulae of the nucleation rate for periodic, disorder, and single-barrier potentials. Using the time-evolving block decimation method, we compute the exact quantum dynamics of the superflow decay in the 1D Bose-Hubbard model at unit filling. From the numerical analyses, we show that the scaling formula is valid for the case of the Bose-Hubbard model, which can quantitatively describe Bose gases in optical lattices.

description: The application of laser guide stars to large aperture telescopes has spurred many new studies in
wavefront sensing. For the particular case of the Shack-HartmannWFS, wavefront sensing is prone to new sources
of errors not previously considered. The primary source of error is spot elongation resulting from the resolution
of the finite thickness of the sodium layer. The elongation spreads the signal over several pixels, resulting in a
decrease of the signal to noise ratio and an increase of non-linearity. Also, the SHWFS performance becomes
sensitive to temporal and spatial variations of the density of the sodium atoms. Among the different centroid
algorithms to be used with this WFS, the most powerful methods (correlation, matched filter, WCoG) require a
reference. Although straightforward for a point source, the use of a resolved laser guide star is more cumbersome
because the sodium layer variations affect their performance. In this paper we look at the impact of the sodium
layer fluctuations and the reference choice on the performance of the WFS, considering real as well as analytical
non-symmetric profiles, and investigating both the subaperture level and the wavefront reconstruction level. We
conclude on the compromise between the use of the best possible reference versus the difficulty of implementation.

description: Sky coverage for MCAO systems has been the subject of a large number of studies in the past decade
or so. The resulting figures, further to have the chance of being refined by actual measurements carried out at the
largest 8m class telescopes, have to be updated and validated for the most recent approaches in ELT adaptive optics
corrections. In particular, techniques employing the use of several virtual deformable mirrors can take advantage
of a field of view, inside which references can be found, that is much larger than the area where the correction
is actually made. While a parallel with similar studies for Multi Objects AO can be traced down, we revise here
the various proposed approaches and we show the results of similar computations using the novel concepts and
gauging the outcome with the more recent on-sky available data.
E6 inspired SUSY models with exact custodial symmetry

Publisher: name: arXiv
Year: 2012
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The breakdown of E_6 gauge symmetry at high energies may lead to supersymmetric (SUSY) models based on the Standard Model (SM) gauge group together with extra U(1)_ψ and U(1)_χ gauge symmetries. To ensure anomaly cancellation the particle content of these E_6 inspired models involves extra exotic states that generically give rise to non-diagonal flavour transitions and rapid proton decay. We argue that a single discrete \tilde{Z}^{H}_2 symmetry can be used to forbid tree-level flavor-changing transitions, as well as the most dangerous baryon and lepton number violating operators. We present 5D and 6D orbifold GUT constructions that lead to the E_6 inspired SUSY models of this type. The breakdown of U(1)_ψ and U(1)_χ gauge symmetries that preserves E_6 matter parity assignment guarantees that ordinary quarks and leptons and their superpartners, as well as the exotic states which originate from 27 representations of E_6 survive to low energies. These E_6 inspired models contain two dark-matter candidates and must also include additional TeV scale vectorlike lepton or vectorlike down type quark states to render the lightest exotic quark unstable. We examine gauge coupling unification in these models and discuss their implications for collider phenomenology and cosmology.

description: The electronic implications of strain in graphene can be captured at low energies by means of pseudovector potentials which can give rise to pseudomagnetic fields. These strain-induced vector potentials arise from the local perturbation to the electronic hopping amplitudes in a tight-binding framework. Here we complete the standard description of the strain-induced vector potential, which accounts only for the hopping perturbation, with the explicit inclusion of the lattice deformations or, equivalently, the deformation of the Brillouin zone. These corrections are linear in strain and are different at each of the strained, inequivalent Dirac points, and hence are equally necessary to identify the precise magnitude of the vector potential. This effect can be relevant in scenarios of inhomogeneous strain profiles, where electronic motion depends on the amount of overlap among the local Fermi surfaces. In particular, it affects the pseudomagnetic field distribution induced by inhomogeneous strain configurations, and can lead to new opportunities in tailoring the optimal strain fields for certain desired functionalities.

Examining the environmental forcing of zooplankton population dynamics : a life history approach using data from a British Columbia fjord
Creators: name: Tommasi, Désirée Alberta Gaia
Publisher: name: University of British Columbia
Year: 2013

description: Zooplankton play a pivotal role in marine ecosystem by cycling carbon and energy up the food chain. The species composition of a zooplankton community can influence such energy transfer pathways in a marine ecosystem. For example, when large calanoid copepods dominate a food web, more of the energy produced by phytoplankton is transferred up the food chain and high biomass of large, lipid-rich calanoid copepods or euphausiids has been associated with higher recruitment of upper trophic levels compared to a system dominated by smaller copepod species. Thus, understanding how environmental forcing drives fluctuations in zooplankton community composition is essential to assessing how the structure of marine ecosystems may vary in the future. However, knowledge of what zooplankton life history strategies or functional traits (e.g. feeding guild) make some species more successful under specific environmental conditions remains limited. Here, using three years of field data on zooplankton abundance, biomass, and species composition from a fjord in British Columbia, Canada, I identified the zooplankton seasonal succession cycle and the controlling effects of different environmental forcing factors on the recruitment success of various zooplankton functional traits. Zooplankton succession was delayed when the spring bloom was late. Furthermore, herbivorous, ontogenetically migrating copepods with a short reproductive season, such as Calanus marshallae and Eucalanus bungii, had reduced recruitment when the spring bloom was delayed or in years of high spring temperature, as compared to omnivorous copepods with a long reproductive season. A population dynamics model was employed to determine the environmental drivers of the observed temporal variability of C. marshallae and E. bungii. Interannual differences in mortality and advection drove the observed change in the recruitment of the two copepod species. High mortality was associated with conditions of low chlorophyll biomass and high temperatures. I suggest that the success of these copepod species may depend on the presence of a low predation-high chlorophyll window in early spring.

Such an important shift in the understanding of fundamental values needs reconfirmation. Using a different approach with electromagnetic form factors of the proton, we obtain a new expression for the transition energy, $Δ= E_{2P_{{3}/{2}}}^{f=2} - E_{2S_{{1}/{2}}}^{f=1}$, in muonic hydrogen and deduce a proton radius, $r_p = 0.831$ fm.

description: Purpose: Early literacy strategies for children from culturally and linguistically diverse (CLD) backgrounds are essential for fostering early academic success. This scoping review aimed to map the existing research in speech-language pathology that describes culturally responsive early literacy interventions.Method: The review followed a five-stage scoping review methodology applied to a multidatabase search. Electronic databases included EBSCO and ASHAWire. Search terms and inclusion criteria identified studies of children from birth to age 5 years from CLD backgrounds, with the goal of identifying early literacy strategies described in speech-language pathology research journals.Results: A total of 23 sources were identified that focused on early intervention for CLD populations. The review highlighted 26 strategies, categorized by strength: 13 with compelling evidence, five with promising evidence, and eight with emerging evidence. These strategies are presented in an evidence map.Conclusions: Shared storybook and dialogic reading strategies can be seamlessly integrated into book-based activities with caregivers from CLD backgrounds. In practice, speech-language pathologists can guide caregivers in a variety of techniques, such as previewing pictures, highlighting illustrations, rereading books, evaluating the child’s responses, asking open-ended questions, and connecting the story to the child’s personal experiences. Dialogic and shared storybook strategies may offer an effective and culturally responsive approach for fostering early literacy skills in young children from CLD backgrounds. Two illustrative case studies are presented, applying strategies from the evidence map to scenarios, and limitations are also discussed.Supplemental Material S1.

description: We derive the off-shell nilpotent and absolutely anticommuting Becchi-Rouet-Stora-Tyutin (BRST) and anti-BRST symmetry transformations for a supersymmetric system of a free spinning relativistic particle within the framework of superfield approach to BRST formalism. A novel feature of our present investigation is the consistent and clear supersymmetric modification of the celebrated horizontality condition for the precise determination of the proper (anti-)BRST symmetry transformations for all the bosonic and fermionic dynamical variables of our theory which is considered on a (1, 2)-dimensional supermanifold parameterized by an even (bosonic) variable (τ) and a pair of odd (fermionic) variables θand \barθ(with θ^2 = \barθ^2 = 0,\; θ\barθ+ \barθθ= 0) of the Grassmann algebra. One of the most important features of our present investigation is the derivation of (anti-)BRST invariant Curci-Ferrari type restriction which turns out to be responsible for the absolute anticommutativity of the (anti-)BRST symmetry transformations and existence of the coupled (but equivalent) Lagrangians for the present theory of a supersymmetric system.

description: Using Magneto-Optical Filters (MOFs) it is possible to see Sodium Laser Guide Stars in the
daytime sky. This makes it possible to use ELT Adaptive Optics systems for diffraction limited
observations 24 hours/day. Because of the bright daytime sky this LGS-AO application is only of interest
in the mid-infrared wavelength region (3.5 – 25 μm) where the thermal radiation of the atmospheretelescope
system dominates the atmospheric scattering of sunlight. Incorporating MOFs in the LGS
wavefront sensors substantially increases the amount of ELT observing time. The gain with respect to the
JWST lies in the 5 - 6 times better linear angular resolution. The contrast gain in brightness at near-IR
wavelengths is sufficient to give enough natural guide stars for tip-tilt control. The main complication
associated with incorporating MOFs in ELT AO systems for daytime observations is likely the
requirement to make the telescope and its enclosure robust in the daytime environment. Poorer daytime
seeing conditions may also be detrimental. The use of Mica etalons and narrow band interference filters is
also briefly examined. The TMT is used as a good option for the implementation of this technique.

description: Extremely Large Telescopes are being designed with integrated AO
modules and most of their instruments will rely on them for their optimum performance.
To reconstruct the wavefront we need to use Guide Stars as references, but
the absence of enough Natural GSs to have a good sky coverage makes it necessary
the use of Laser GSs. Several technical challenges have to be solved in order to perform
a good wavefront reconstruction using LGSs. In the case of Na LGSs we need
to know the height at which the LGS is focused and the profile and extension of the
Na layer.We propose the use of a plenoptic camera to obtain this information. The
plenoptic camera was originally created to allow the capture of the Light Field, a
four-variable volume representation of all rays and their directions, that allows the
creation by synthesis of a 3D image of the observed object. This 3D reconstruction
make it possible to retrieve the distances at which the objects are, and for this reason
it is especially adequate to measure the height variations of the LGS beacons.
This novel approach provides real-time information on the Na layer profile that
can be introduced in the reconstruction algorithm to solve the problems derived
by the spot elongation. Also we can compute at which height the LGS is focused,
overcoming therefore the two challenges mentioned before. We present in this paper
the laboratory results obtained with a setup simulating the laser spot and the
telescope equipped with the plenoptic camera that proof that the expected height
of the layers is retrieved. We also present our plans to implement on-sky tests of
our system using the Na LGS of the Optical Ground Station in the Observatorio de
Tenerife, and the application of this advanced concept to the E-ELT.

description: A study of magnetic flux penetration in a superconducting film patterned with arrays of micron sized antidots (microholes) is reported. Magneto-optical imaging (MOI) of a YBCO film shaped as a long strip with perpendicular antidot arrays revealed both strong guidance of flux, and at the same time large perturbations of the overall flux penetration and flow of current. These results are compared with a numerical flux creep simulation of a thin superconductor with the same antidot pattern. To perform calculations on such a complex geometry, an efficient numerical scheme for handling the boundary conditions of the antidots and the nonlocal electrodynamics was developed. The simulations reproduce essentially all features of the MOI results. In addition, the numerical results give insight into all other key quantities, e.g., the electrical field, which becomes extremely large in the narrow channels connecting the antidots.

description: ARGOS - the Laser Guide Star adaptive optics facility for the Large Binocular Telescope will enable a wide field high order ground layer correction of the atmospheric induced distortions. By projecting a constellation of multiple laser guide stars above each of the 8.4m primary mirrors of the LBT, ARGOS in its ground layer mode will enable a wide field adaptive optics correction for multi object spectroscopy. ARGOS implements high power pulsed green lasers and makes use of Rayleigh scattering for the guide star creation. The geometric relations of this setup in guide star height vs. primary diameter are quite comparable to an ELT with sodium guide stars. The use of LBT's adaptive secondary mirror, gated wavefront sensors, a prime focus calibration system and the laser constellation shows several aspects that can be used as path-finder technology for the planned ELTs. In already planned upgrade steps with a hybrid Sodium-Rayleigh combination ARGOS will enable MCAO and MOAO implementations at LBT allowing unique astronomical observations.

description: For the ELTs the use of AO with multiple sodium Laser Guide Stars will be routine. We think it is important to study the LGS generation in order to optimize the LGS-AO systems. It is in this context that we are working on the understanding and optimization of the laser parameters. In this paper we report on a part of our LGS return flux studies, aimed at identifying the optimal laser formats for CW and pulsed lasers. We have done recently numerical simulations on the LGS return flux for different laser formats, solving the Bloch equations for the interaction of the mesospheric sodium atoms with the laser radiation. The simulations have been used for the design of the future ESO LGS facilities. However the simulations need to be validated. We report on the ESO Wendelstein transportable 20W LGS unit, recently built and commissioned to make systematic field studies on the LGS. The first experimental results on the LGS return flux obtained during the commissioning are reported.

description: The adaptive optics facility (AOF) designed for the Very Large Telescope (VLT) in Chile will be
equipped with a deformable secondary mirror (DSM). The calibration procedure of the interaction matrix, which
characterizes the system and the relationship between the DSM commands and the wavefront sensors (WFS)
slopes, will be more complex than for the previous systems at the VLT since it will have to be measured on sky and
for a much larger number of degrees of freedom (1170 actuators). In addition, gravity or temperature variations
for instance are likely to introduce slow evolution of the matching between the DSM and the WFS geometry.
This can occur during observations and therefore degrade the adaptive optics (AO) correction. To relax the need
of frequent painful calibrations and to prevent a loss of performance due to misregistrations, we investigate how
to track the evolution of the interaction matrix errors in closed-loop without introducing any degradation in the
observations. This is done thanks to identification methods and optimization theory. First, we formally describe
the closed-loop problem and its specificities. Then, we present a solution, based on the optimization of the error
of estimates of the WFS slopes, at the output of the closed-loop AO. The performance of this method and its
limitations are analyzed formally and thanks to numerical simulations of an AO system somehow characteristic
of the ones expected in the AOF.
The Product Life Cycle of Durable Goods

description: A dynamic model of the product lifecycle of (nearly) homogeneous durables in polypoly markets is established. It describes the concurrent evolution of the unit sales and price of durable goods. The theory is based on the idea that the sales dynamics is determined by a meeting process of demanded with supplied product units. Taking advantage from the Bass model for first purchase and a logistic model for repurchase the entire product lifecycle of a durable can be established. For the case of a fast growing supply the model suggests that the mean price of the good decreases according to a logistic law. Both, the established unit sales and price evolution are in agreement with the empirical data studied in this paper. The presented approach discusses further the interference of the diffusion process with the supply dynamics. The model predicts the occurrence of lost sales in the initial stages of the lifecycle due to supply constraints. They are the origin for a retarded market penetration. The theory suggests that the imitation rate B indicating social contagion in the Bass model has its maximum magnitude for the case of a large amount of available units at introduction and a fast output increase. The empirical data of the investigated samples are in qualitative agreement with this prediction.

description: GeMS, the Gemini MCAO system, is undergoing commissioning. Using 5 laser guide stars and a
central launch, GeMS is particularly sensitive to Rayleigh backscatter and the fratricide effect. Using data covering
a 5 months period from January to May 2011, we present results on (i) the Sodium return and its variability from
night to night, (ii) the spot elongation and (iii) the fratricide effect. A simple modeling of the fratricide is presented
as well as possible strategies for mitigation.
