description: We revisit the problem of the decoherence and relaxation of a central spin coupled to a bath of conduction electrons. We consider both metallic and semiconducting baths to study the effect of a gap in the bath density of states (DOS) on the time evolution of the density matrix of the central spin. We use two weak coupling approximation schemes to study the decoherence. At low temperatures, though the temperature dependence of the decoherence rate in the case of a metallic bath is the same irrespective of the details of the bath, the same is not true for the semiconducting bath. We also calculate the relaxation and decoherence rates as a function of external magnetic fields applied both on the central spin and the bath. We find that in the presence of the gap, there exists a certain regime of fields, for which surprisingly, the metallic bath has lower rates of relaxation and decoherence than the semiconducting bath.

description: Recent work on approximate quantum error correction (QEC) has opened up the possibility of constructing subspace codes that protect information with high fidelity in scenarios where perfect error correction is impossible. Motivated by this, we investigate the problem of approximate subsystem codes. Subsystem codes extend the standard formalism of subspace QEC to codes in which only a subsystem within a subspace of states is used to store information in a noise-resilient fashion. Here, we demonstrate easily checkable sufficient conditions for the existence of approximate subsystem codes. Furthermore, for certain classes of subsystem codes and noise processes, we prove the efficacy of the transpose channel as a simple-to-construct recovery map that works nearly as well as the optimal recovery channel. This work generalizes our earlier approach [H.K. Ng and P. Mandayam, Phys. Rev. A 81 062342 (2010)] of using the transpose channel for approximate correction of subspace codes to the case of subsystem codes, and brings us closer to a unifying framework for approximate QEC.

description: Wide Field Adaptive Optics (WFAO) concepts are currently being studied in the perspec-
tive of future ELT instrumentation. In that context, the ONERA wide field AO facility (HOMER
bench) has been developed. HOMER allows the implementation and comparison of control schemes
from the simplest least-square to the optimal Linear Quadratic Gaussian solutions including Pseudo-
closed loop approach. After a description of the bench internal calibrations and ultimate performance,
all these control schemes are compared experimentally in a Laser Tomography AO configuration.
On the reflection of Alfvén waves and its implication for Earth's core modeling

description: Alfvén waves propagate in electrically conducting fluids in the presence of a magnetic field. Their reflection properties depend on the ratio between the kinematic viscosity and the magnetic diffusivity of the fluid, also known as the magnetic Prandtl number Pm. In the special case Pm=1, there is no reflection on an insulating, no-slip boundary, and the wave energy is entirely dissipated in the boundary layer. We investigate the consequences of this remarkable behaviour for the numerical modeling of torsional Alfvén waves (also known as torsional oscillations), which represent a special class of Alfvén waves, in rapidly rotating spherical shells. They consist of geostrophic motions and are thought to exist in the fluid cores of planets with internal magnetic field. In the geophysical limit Pm << 1, these waves are reflected at the core equator, where they are entirely absorbed for Pm=1. Our numerical calculations show that the reflection coefficient at the equator of these waves remains below 0.2 for Pm > 0.3, which is the range of values for which geodynamo numerical models operate. As a result, geodynamo models with no-slip boundary conditions cannot exhibit torsional oscillation normal modes.

description: Adaptive optics (AO) systems correct for atmospheric distortion in real time in order to produce
sharper images and enhance scientific capabilities. Sky coverage is greatly increased by the use of laser guide
stars generated by resonant excitation of mesospheric sodium atoms. However, physical processes in the upper
atmosphere affect the performance of such systems. Competing processes of meteoric ablation that produce,
and chemical reactions that remove, sodium atoms, govern the extent and density of the sodium region. The
structure of this region is affected by gravity waves, wind shear and turbulence that cause temporal and spatial
density variations and thus affect the mean sodium altitude and consequently produce focus-induced wavefront
errors, degrading AO performance. In order to better quantify these effects, we developed a high-performance
sodium lidar system for the 6-m Large Zenith Telescope. With a power-aperture product more than two orders of
magnitude greater than most atmospheric lidar systems, the facility is capable of recording sodium density profiles
with sub-second and meter-scale resolution. A recent upgrade enables us to simulate laser guide star asterisms and
directly measure horizontal structure variations by chopping a pulsed laser beam horizontally within the 1 arcmin
field of view. The 2d mean altitude structure function shows the variance in variation is hence linked to differential
focus errors, an important aspect for multi-laser guide star facilities and multi-object adaptive optics.
Line formation in the inner winds of classical T Tauri stars: testing the conical-shell wind solution

description: We present the emission line profile models of hydrogen and helium based on the results from axisymmetric magnetohydrodynamics (MHD) simulations of the wind formed near the disk-magnetosphere boundary of classical T Tauri stars (CTTSs). We extend the previous outflow models of `the conical-shell wind' by Romanova et al. to include a well defined magnetospheric accretion funnel flow which is essential for modelling the optical and near-infrared hydrogen and helium lines of CTTSs. The MHD model with an intermediate mass-accretion rate shows outflows in conical-shell shape with a half opening angle about 35 degrees. The flow properties such as the maximum outflow speed in the conical-shell wind, maximum inflow speed in the accretion funnel, mass-accretion and mass-loss rates are comparable to those found in a typical CTTS. The density, velocity and modified temperature from the MHD simulations are used in a separate radiative transfer model to predict the line profiles and test the consistency of the MHD models with observations. The line profiles are computed with various combinations of X-ray luminosities, temperatures of X-ray emitting plasma, and inclination angles. A rich diversity of line profile morphology is found, and many of the model profiles are very similar to those found in observations. We find that the conical-shell wind may contribute to the emission in some hydrogen lines (e.g. H-alpha, H-beta, Pa-beta and Pa-gamma) significantly when the temperature in the wind is relatively high (e.g. \sim 10^{4} K); however, the wind contribution decreases rapidly when a lower wind temperature is adopted. The model well reproduces a relatively narrow and low-velocity blueshifted absorption component in He I (10830), which are often seen in observations.

description: We show that multi-orbital and density-induced tunneling have a significant impact on the phase diagram of bosonic atoms in optical lattices. Off-site interactions lead to density-induced hopping, the so-called bond-charge interactions, which can be identified with an effective tunneling potential and can reach the same order of magnitude as conventional tunneling. In addition, interaction-induced higher-band processes also give rise to strongly modified tunneling, on-site and bond-charge interactions. We derive an extended occupation-dependent Hubbard model with multi-orbitally renormalized processes and compute the corresponding phase diagram. It substantially deviates from the single-band Bose-Hubbard model and predicts strong changes of the superfluid to Mott-insulator transition. In general, the presented beyond-Hubbard physics plays an essential role in bosonic lattice systems and has an observable influence on experiments with tunable interactions.

description: Entering the ELT era implies reconsidering adaptive optics concepts at all levels, including controller
design. Concentrating mainly on temporal aspects, one may wonder if integral controllers remain an adequate
solution.We recall for instance the impressive correction brought by Linear Quadratic Gaussian (LQG) controllers
for the rejection of windshake and vibration components. Based on this experience, we present here a careful
evaluation of the respective performance of integrator versus LQG control on turbulent modes both in a VLT and
ELT configuration. The main questions addressed are: 1/ How do integral and LQG controllers compare in terms
of performance for a given sampling frequency and noise level?; 2/ Could we relax sampling frequency and noise
level specifications with LQG control?; 3/ How are these considerations affected by the choice of open-loop rather
than closed-loop strategies? What about LQG in the context of large degrees of freedom?

$R$-closed homeomorphisms on surfaces

description: Let $f$ be an $R$-closed homeomorphism on a connected orientable closed surface $M$. In this paper, we show that If $M$ has genus more than one, then each minimal set is either a periodic orbit or an extension of a Cantor set. If $M = \mathbb{T}^2$ and $f$ is neither minimal nor periodic, then either each minimal set is finite disjoint union of essential circloids or there is a minimal set which is an extension of a Cantor set. If $M = \mathbb{S}^2$ and $f$ is not periodic but orientation-preserving (resp. reversing), then the minimal sets of $f$ (resp. $f^2$) are exactly two fixed points and other circloids and $\mathbb{S}^2/\widetilde{f} \cong [0, 1]$.

description: A thermodynamically consistent two-phase Stefan problem with temperature-dependent surface tension and with or without kinetic undercooling is studied. It is shown that these problems generate local semiflows in well-defined state manifolds. If a solution does not exhibit singularities, it is proved that it exists globally in time and converges towards an equilibrium of the problem. In addition, stability and instability of equilibria is studied. In particular, it is shown that multiple spheres of the same radius are unstable if surface heat capacity is small; however, if kinetic undercooling is absent, they are stable if surface heat capacity is sufficiently large.

description: The 4LGSF is to be installed as a subsystem of the ESO Adaptive Optics Facility (AOF, [1]) on Unit Telescope 4 (UT4) of the VLT, to provide the AO instruments GALACSI/MUSE and GRAAL/HAWK-I with four sodium laser guide stars. The 4LGSF will deploy four modular LGS Units at the UT4 Centrepiece. Two key aspects of the 4LGSF design are: (i) new industrial laser source (fibre lasers) with reduced volume, reduced need of maintenance, higher reliability, simpler operation and optimised spectral format for highly efficient sodium excitation, (ii) modular structure of the four LGS Units, composed of the laser and laser launch telescope, capable to operate independently of the others. The final design of the 4LGSF is now complete and the project has entered the manufacturing, assembly, integration and test phase. Furthermore, modular LGS units containing the laser emitter integrated on the launch telescope have already been demonstrated at ESO in the past years [2, 3]. We believe that having the laser sources as an integral part of a modular unit together with the launching optics offers many advantages at the system level, including the avoidance of laser beam relays, retaining the flexibility to use as many LGS as required independently, and the possibility of building redundancy into the system. Many of these 4LGSF concepts can serve for ELT multi-LGS-assisted adaptive telescope designs and provide a valuable experience in advance of the ELTs.

description: The effects of stressful life events on violent victimization have been well established. The existing literature, however, remains relatively limited in examining the indirect association between stressful life events and violent victimization through acquired psychological processes. The current study examines the mediating effects of the co-occurrence of negative psychological symptoms (adverse psychological effects) on the association between stressful life events and violent victimization. The results of two structural equation models, estimated using the NLSY 1997 cohort, demonstrate that a variety of stressful life events and violent victimization had a positive indirect effect on violent victimization through adverse psychological effects. The results were only slightly attenuated when self-reported number of arrests was introduced as a covariate of violent victimization in the SEM. The findings suggest that exposure to a variety of stressful life events and violent victimization can influence psychological symptoms and increase subsequent violent victimization.

description: Anisotropic emission of gravitational waves (GWs) from inspiralling compact binaries leads to the loss of linear momentum and hence gravitational recoil of the system. The loss rate of linear momentum in the far-zone of the source (a nonspinning binary system of black holes in quasicircular orbit) is investigated at the 2.5 post-Newtonian (PN) order and used to provide an analytical expression in harmonic coordinates for the 2.5PN accurate recoil velocity of the binary accumulated in the inspiral phase. We find that the recoil velocity at the end of the inspiral phase (i.e at the innermost stable circular orbit (ISCO)) is maximum for a binary with symmetric mass ratio of ν~0.2 and is roughly about ~4.58 km/s. Going beyond inspiral, we also provide an estimate of the more important contribution to the recoil velocity from the plunge phase. Again the recoil velocity at the end of the plunge, involving contributions both from inspiral and plunge phase, is maximum for a binary with ν~0.2 and is of the order of ~180 km/s.

Random Transverse Field Ising Model in dimension $d>1$ : scaling analysis in the disordered phase from the Directed Polymer model

description: For the quantum Ising model with ferromagnetic random couplings $J_{i,j}>0$ and random transverse fields $h_i>0$ at zero temperature in finite dimensions $d>1$, we consider the lowest-order contributions in perturbation theory in $(J_{i,j}/h_i)$ to obtain some information on the statistics of various observables in the disordered phase. We find that the two-point correlation scales as : $\ln C(r) \sim - \frac{r}{ξ_{typ}} +r^ω u$, where $ξ_{typ} $ is the typical correlation length, $u$ is a random variable, and $ω$ coincides with the droplet exponent $ω_{DP}(D=d-1)$ of the Directed Polymer with $D=(d-1)$ transverse directions. Our main conclusions are (i) whenever $ω>0$, the quantum model is governed by an Infinite-Disorder fixed point : there are two distinct correlation length exponents related by $ν_{typ}=(1-ω)ν_{av}$ ; the distribution of the local susceptibility $χ_{loc}$ presents the power-law tail $P(χ_{loc}) \sim 1/χ_{loc}^{1+μ}$ where $μ$ vanishes as $ξ_{av}^{-ω} $, so that the averaged local susceptibility diverges in a finite neighborhood $00$ (for instance $ω(d=2)=1/3$ and $ω(d=3) \sim 0.24$) (iii) in finite dimensions $d > 3$, a finite disorder strength is necessary to flow towards the Infinite-Disorder fixed point with $ω(d)>0$ (for instance $ω(d=4) \simeq 0.19$), whereas a Finite-Disorder fixed point remains possible for a small enough disorder strength. For the Cayley tree of effective dimension $d=\infty$ where $ω=0$, we discuss the similarities and differences with the case of finite dimensions.

description: FAIR-IMPACT's series of FAIR Implementation Workshops aimed to help three key stakeholder groups - Research performing Organisations, Repositories & Data Service Providers, and National Level Initiatives - to become familiar with FAIR-enabling tools, approaches and methods. Each workshop provided an overview of a specific FAIR-enabling activity, shared information on recent developments both from within FAIR-IMPACT and other initiatives as well as offering examples of good practice, practical tips and recommendations. Each workshop included plenty of time for questions and discussion. Registration was free and open to all.

The format of FAIR-IMPACT's FAIR Implementation Workshops was designed specifically to provide concise and practically focused introductions to current and emerging methods and approaches. By offering the series virtually, keeping within a 1-2 hour duration, and ensuring that workshop recordings were provided, FAIR-IMPACT aimed to reduce barriers to potential participants. The format of delivery has proven popular with up to 300 registrants signing up for each of our virtual workshops and many people joining more than one workshop.

Continuation of the event series could help to ensure that new approaches and tools are shares as they emerge through ongoing and future INFRAEOSC projects can be shared in an easily digestible formt. To support reuse of the approach, FAIR-IMPACT has created a blueprint for planning and delivering FAIR Implementation workshops.

description: The application of organic fertilizers (OF) can supply carbon (C) to the soil in crop fields. OF-derived C (OF-C) is often estimated using the differential method that can be biased due to indirect effects of OF on soil C. This study tested three methods to quantify OF–C: (i) the widespread differential method, (ii) the synchronic isotope method comparing plots with and without OF and (iii) the asynchronic isotope method mimicking a trial without a control plot. These methods were implemented on an Arenosol and an Andosol supplied during 13 years with slurry or compost. The results highlighted the relevance of using the synchronic isotope method, which focuses on the direct effect of OFs on the soil organic matter (without bias of vegetation change) and considers control soil’s evolution. The higher the isotopic difference between soil and OF, the shorter the method implementation time needed: for an initial difference of 7.5 ‰ and 3.5 ‰, quantification is suitable after 4 and 9 years of fertilization respectively. Attention should be paid to OF-δ13C variability to guarantee the method validity. The method proved to be suitable to study the factors controlling the OF-C fate in tropical soils.

 DESCRIPTION. Body length 3-4,5 mm. Black in dark-brown microtomentum. Frons with 2 black isolated stripes; orbita and ocellar triangle brown. Face in dark brown, occiput in grey microtomentum. Face with 2 strong setae and 1 shorter hair below them. Palpae yellow. Arista with 6 rays. Thorax brown, scutum with 3 greyish stripes, katepisternum grey. Both npl setae are equal in size. Halters brown. Wings grayish almost hyaline or brownish, veins black. Legs black, tarsi yellowish, darkened dorsally. Abdomen black. Tergite IV with 4-10 long posteriorly directed setae, tergite V elongated in slender tube with 2 apical setae. Basal fused part of surstyli narrow, apical parts of surstyli directed outside (Fig. 4), curved surstyli equal to adjoining part of epandrium (Fig. 5), the shape of surstyli in lateral view differing form those of “transversa”. Male abdominal sternite 5th as long as wide, with 4 projections anteriorly; abdominal sternite 4th longer than wide (Figs 8-9).

 2007); 11 – D. ussurica (original).
 NOTES. As for the lectotype specimen of the Dichaeta transversa is in poor condition, I couldn't compare external characters of D. transversa and D. ussurica. However the differences in the structure of abdominal sternites are distinct: abdominal sternite 5th of D. transversa 2 times as long as wide and bilobed anteriorly; this sternite is of about rectangular shape and with 4 small anterior projections in D. ussurica; the shape of abdominal sternite 4th is distinct also. Genitalia are also different: basal fused part of surstyli broad in D. transversa and narrow in D. ussurica, apical parts of surstyli directed inside in the former species and outside in the latter; curved surstyli longer than adjoining part of epandrium in D. transvesra and equal to it in D. ussurica. The areas of two species are very different and testify to their geographical isolation. Herein I restore Dichaeta ussurica as a good species.
 Two distributed in Russia species of Dichaeta can be distinguished by the following characters.

description: With the increasing size of today's data sets, finding the right parameter configuration in model selection via cross-validation can be an extremely time-consuming task. In this paper we propose an improved cross-validation procedure which uses nonparametric testing coupled with sequential analysis to determine the best parameter set on linearly increasing subsets of the data. By eliminating underperforming candidates quickly and keeping promising candidates as long as possible, the method speeds up the computation while preserving the capability of the full cross-validation. Theoretical considerations underline the statistical power of our procedure. The experimental evaluation shows that our method reduces the computation time by a factor of up to 120 compared to a full cross-validation with a negligible impact on the accuracy.

description: We compute the contribution to the scalar metric perturbations from large-scale magnetic fields which are generated during inflation. We show that apart from the usual passive and compensated modes, the magnetic fields also contribute to the constant mode from inflation. This is different from the causal (post inflationary) generation of magnetic fields where such a mode is absent and it might lead to significant, non-Gaussian CMB anisotropies.

description: We present an experimental investigation of the dynamic spin response of a strongly interacting Fermi gas using Bragg spectroscopy. By varying the detuning of the Bragg lasers, we show that it is possible to measure the response in the spin and density channels separately. At low Bragg energies, the spin response is suppressed due to pairing, whereas the density response is enhanced. These experiments provide the first independent measurements of the spin-parallel and spin-antiparallel dynamic and static structure factors and open the way to a complete study of the structure factors at any momentum. At high momentum the spin-antiparallel dynamic structure factor displays a universal high frequency tail, proportional to $ω^{-5/2}$, where $\hbar ω$ is the probe energy.

description: During the last decade of network research focusing on structural and dynamical properties of networks, the role of network users has been more or less underestimated from the bird's-eye view of global perspective. In this era of global positioning system equipped smartphones, however, a user's ability to access local geometric information and find efficient pathways on networks plays a crucial role, rather than the globally optimal pathways. We present a simple greedy spatial navigation strategy as a probe to explore spatial networks. These greedy navigators use directional information in every move they take, without being trapped in a dead end based on their memory about previous routes. We suggest that the centralities measures have to be modified to incorporate the navigators' behavior, and present the intriguing effect of navigators' greediness where removing some edges may actually enhance the routing efficiency, which is reminiscent of Braess's paradox. In addition, using samples of road structures in large cities around the world, it is shown that the navigability measure we define reflects unique structural properties, which are not easy to predict from other topological characteristics. In this respect, we believe that our routing scheme significantly moves the routing problem on networks one step closer to reality, incorporating the inevitable incompleteness of navigators' information.

description: We reconsider observables for discovering and measuring the mass of a Higgs boson via its di-leptonic decays: H --> WW* --> l nu l nu. We define an observable generalizing the transverse mass that takes into account the fact that one of the intermediate W-bosons is likely to be on-shell. We compare this new variable with existing ones and argue that it gives a significant improvement for discovery in the region m_h < 2 m_W.

description: The CANARY instrument is an MOAO demonstrator instrument for the E-ELT EAGLE instrument,
fielded on the William Herschel Telescope. We present the CANARY real-time control system, both as used onsky
for the NGS only phase in 2010, and also as will be used on-sky in September 2012 with tomographic LGS
capability and four LGSs. This system is based on the Durham AO Real-time Controller (DARC), for which
we provide details of the main features. The challenges that we encountered will be presented as a learning
experience, including camera synchronisation issues, and problems with a reliable telemetry on a loaded network.
We will also present recent progressmade in implementing a real-time control systemfor EAGLE in the laboratory
in Durham, and the implications that this design has. By using a system comprised of a small number of high end
GPU accelerators, theoretical performance is enough to perform matrix-vector based wavefront reconstruction for
EAGLE, and we investigate whether this is a practical solution.
Energetics of particle collisions near dirty rotating extremal black holes: Banados-Silk-West effect versus Penrose process

description: If two particles collide near the horizon of a rotating extremal black hole, under certain conditions the energy E_{c.m.} in the center-of-mass frame can grow without limit (the so-called Banados-Silk-West effect). We consider collisions that produce two other particles. We show that for a generic dirty (surrounded by matter) black hole, there exist upper bounds on the energy and mass of product particles which can be detected at infinity. As a result, the positive energy gain is possible but is quite modest. It mainly depends on two numbers in which near-horizon behavior of the metric is encoded. The obtained results suggest astrophysical limits on the possibility of observation of the products of the collisional Banados-Silk-West effect. These results are consistent with recent calculations for the Kerr metric, extending them to generic dirty black holes. It is shown that for dirty black holes there are types of scenarios of energy extraction impossible in the Kerr case.

description: LINC-NIRVANA is an imaging Fizeau interferometer, for use in near infrared wavelengths, being
built for the Large Binocular Telescope. Multi-conjugate adaptive optics (MCAO) increases the sky coverage
and the field of view over which diffraction limited images can be obtained. For its MCAO implementation,
Linc-Nirvana utilizes four total wavefront sensors; each of the two beams is corrected by both a ground-layer
wavefront sensor (GWS) and a high-layer wavefront sensor (HWS). The GWS controls the adaptive secondary
deformable mirror (DM), which is based on an DSP slope computing unit. Whereas the HWS controls an
internal DM via computations provided by an off-the-shelf multi-core Linux system. Using wavefront sensor data
collected from a prior lab experiment, we have shown via simulation that the Linux based system is sufficient
to operate at 1 kHz, with jitter well below the needs of the final system. Based on that setup we implemented
an adaptive optics loop control application which includes the back-end number crunching loop pipeline from
camera readout to the DM. All intermediate steps of the loop are controlled by modular engineering GUI front-
ends for diagnostic and configuration. Those engineering front-ends can either be used together with the slope
computing unit (Basic Computation Unit BCU) which is used by the GWS and the initial Pathfinder setup or
with the Linux based system (for MCAO operation of the HWS). The implementation of the Linux based system
is done similar to the internal process of the BCU. In this way both systems provide the same functionalities and
can be maintained more easily.
