description: We present a numerical scheme, implemented in the cosmological adaptive mesh refinement code ENZO, to model the injection of Cosmic Ray (CR) particles at shocks, their advection and their dynamical feedback on thermal baryonic gas. We give a description of the algorithms and show their tests against analytical and idealized one-dimensional problems. Our implementation is able to track the injection of CR energy, the spatial advection of CR energy and its feedback on the thermal gas in run-time. This method is applied to study CR acceleration and evolution in cosmological volumes, with both fixed and variable mesh resolution. We compare the properties of galaxy clusters with and without CRs, for a sample of high-resolution clusters with different dynamical states. At variance with similar simulations based on Smoothed Particles Hydrodynamics, we report that the inclusion of CR feedback in our method decreases the central gas density in clusters, thus reducing the X-ray and Sunyaev-Zeldovich effect from the clusters centre, while enhancing the gas density and its related observables near the virial radius.

description: We define quaternionic Hermite polynomials by analogy with two families of complex Hermite polynomials. As in the complex case, these polynomials consatitute orthogonal families of vectors in ambient quaternionic $L^2$-spaces. Using these polynomials, we then define regular and anti-regular subspaces of these $L^2$-spaces, the associated reproducing kernels and the ensuing quaternionic coherent states.

description: It is generally believed that classical regime emerges as a limiting case of quantum theory. Exploring such quantum-classical correspondences in a more transparent manner is central to the deeper understanding of foundational aspects and has attracted a great deal of attention - starting from the early days of quantum theory. While it is often highlighted that quantum to classical transition occurs in the limit hbar tending to zero, several objections have been raised about its suitability in some physical contexts. Ehrenfest's theorem is another widely discussed classical limit - however, its inadequacy has also been pointed out in specific examples. It has been proposed that since a quantum mechanical wave function inherits an intrinsic statistical behavior, its classical limit must correspond to a classical ensemble - not an individual particle. This opens up the question "how would uncertainty relations of canonical observables compare themselves in quantum and classical realms?" In this paper we explore parallels between uncertainty relations in stationary states of quantum systems and that in the corresponding classical ensemble. We confine ourselves to one dimensional conservative systems and show, with the help of suitably defined dimensionless physical quantities, that first and second moments of the canonical observables match with each other in classical and quantum descriptions - resulting in an identical structure for uncertainty relations in both the realms.

title: Aggregate opportunity modelling for New Zealand
Creators: name: Hill, Matthew P.
Publisher: name: GNS Science
Year: 2021

description: Efficient utilisation of New Zealand’s aggregate resources is critical to supporting infrastructure development as well as reducing operational and transport costs related to extraction of the raw materials. A mineral potential modelling approach has been used to identify places with opportunity for future hard rock and gravel extraction across New Zealand. Geographic information system (GIS) software has been used to build a spatial model of the critical components of aggregate opportunity using digital geological, land-use, statistical and geographic data. Model components include source rocks, land use, future demand, supporting infrastructure and cultural sensitivity that use 23 mappable criteria layers. These are combined using the fuzzy logic expert-weighted spatial modelling technique to qualitatively rank aggregate resource opportunities at a national scale. The resulting maps and their GIS based equivalent datasets of gravel and hard rock aggregate opportunity can be used to manage aggregate resources, generate targets for exploration activities and provide insight into future resources.

description: This document is a letter reporting the results of an Archaeological Study Supporting the Repair of Two Culverts on Vandenberg Space Force Base (VSFB). The project will entail reinforcing the existing culvert structures that serve to divert storm runoff under the access roads. On October 8, 2021, Applied EarthWorks’ field supervisor and two field technicians conducted a pedestrian survey and excavated 11 shovel test pits to assess whether surface or subsurface archaeological deposits exist within the project areas. The VSFB cultural resources manager provided maps depicting shovel test pit locations. Native American monitoring was provided by the Santa Ynez Band of Chumash Indians, and unexploded ordnance monitoring was provided by Pennmax. The surface survey did not reveal any prehistoric or historical remains.

description: We present 5--38 $μ$m spectroscopic observations of a sample of 68 ISOGAL sources with unknown natures, taken with the Spitzer Infrared Spectrograph. Based on the characteristics and the slope of their spectra we classified the sources as young or late-type evolved objects. These sources were selected to test selection criteria based on the ISOGAL [7]--[15] color and the spatial extent parameter $σ_{\rm 15}$. We revised these criteria until they reliably distinguished between young and late-type evolved objects and then applied them to all ISOGAL sources in the central molecular zone (CMZ), resulting in the selection of 485 sources believed to be young. Furthermore, we added 656 Midcourse Space Experiment (MSX) sources to the CMZ sample that fulfilled $F_{\rm E}/F_{\rm D} > 2$ with $F{\rm D}$ and $F_{\rm E}$ being the flux densities in the D (15 $μ$m) and E (21 $μ$m) bands. After obtaining $\frac{L_{\rm bol}}{F_{\rm 15}}$ conversion factors, we calculated the bolometric luminosity, $L_{\rm bol}$, values for the CMZ sample and subsequently the masses of the sources. Applying a Kroupa initial mass function, we derived the total mass in young objects that has been formed over the last 1 Myr, resulting in an average star formation rate of 0.08 solar masses per year for the CMZ.

Mixed-mode oscillations in a multiple time scale phantom bursting system

description: In this work we study mixed mode oscillations in a model of secretion of GnRH (Gonadotropin Releasing Hormone). The model is a phantom burster consisting of two feedforward coupled FitzHugh-Nagumo systems, with three time scales. The forcing system (Regulator) evolves on the slowest scale and acts by moving the slow nullcline of the forced system (Secretor). There are three modes of dynamics: pulsatility (transient relaxation oscillation), surge (quasi steady state) and small oscillations related to the passage of the slow nullcline through a fold point of the fast nullcline. We derive a variety of reductions, taking advantage of the mentioned features of the system. We obtain two results; one on the local dynamics near the fold in the parameter regime corresponding to the presence of small oscillations and the other on the global dynamics, more specifically on the existence of an attracting limit cycle. Our local result is a rigorous characterization of small canards and sectors of rotation in the case of folded node with an additional time scale, a feature allowing for a clear geometric argument. The global result gives the existence of an attracting unique limit cycle, which, in some parameter regimes, remains attracting and unique even during passages through a canard explosion.

description: This document is a report Identifying the Historic Properties and Assessment of Effected for the American Water Grubbing and Vegetation Removal behind Building 856 Project. The grubbing activity has the potential to uproot vegetation and therefore cause subsurface disturbance. Three sites were found to be within the survey area; CA-SBA-923, CA-SBA-2952, and CA-SBA-3107H. Vandenberg Space Force Base is seeking State Historic Preservation Office concurrence that 1) the area of direct impact was adequately delineated, 2) CA-SBA-923 and CA-SBA-2952 will be assumed eligible for the National Register for this undertaking only, and 3) there will be no adverse effect to historic properties for this project.
0065 Art and politics in the former "Portuguese Colonial Empire"

description: In 1940, a monument to Mouzinho de Albuquerque is inaugurated in the former capital of the Portuguese Colony of Mozambique, Lourenço Marques. The result of a lenghty commissioning process, this homage to one of the main heroes of the colonial pantheon becomes a center-piece in the many political rituals which had become common-place during the 1930s. The concepts of aura and cult value are used to analyse its "traditionalist" aesthetics and the role it played in political spectacles, arguing that it obeys a strategy of representation of the public space as "Empire".

Measurement of the Diffractive Longitudinal Structure Function F_L^D at HERA
Creators: name: H1 Collaboration
Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: First measurements are presented of the diffractive cross section $σ_{ep \rightarrow eXY}$ at centre-of-mass energies $\sqrt{s}$ of 225 and 252 GeV, together with a precise new measurement at $\sqrt{s}$ of 319 GeV, using data taken with the H1 detector in the years 2006 and 2007. Together with previous H1 data at $\sqrt{s}$ of 301 GeV, the measurements are used to extract the diffractive longitudinal structure function F_L^D in the range of photon virtualities 4.0 <= Q^2 <= 44.0 GeV^2 and fractional proton longitudinal momentum loss 5 10^{-4} <= x_{IP} <= 3 10^{-3}. The measured F_L^D is compared with leading twist predictions based on diffractive parton densities extracted in NLO QCD fits to previous measurements of diffractive Deep-Inelastic Scattering and with a model which additionally includes a higher twist contribution derived from a colour dipole approach. The ratio of the diffractive cross section induced by longitudinally polarised photons to that for transversely polarised photons is extracted and compared with the analogous quantity for inclusive Deep-Inelastic Scattering.

description: We present the first analysis of extended stellar kinematics of elliptical galaxies where a Yukawa--like correction to the Newtonian gravitational potential derived from f(R)-gravity is considered as an alternative to dark matter. In this framework, we model long-slit data and planetary nebulae data out to 7 Re of three galaxies with either decreasing or flat dispersion profiles. We use the corrected Newtonian potential in a dispersion-kurtosis Jeans analysis to account for the mass-anisotropy degeneracy. We find that these modified potentials are able to fit nicely all three elliptical galaxies and the anisotropy distribution is consistent with that estimated if a dark halo is considered. The parameter which measures the "strength" of the Yukawa-like correction is, on average, smaller than the one found previously in spiral galaxies and correlates both with the scale length of the Yukawa-like term and the orbital anisotropy.

0101 Committenze europee di scultura veneziana nel Settecento
Creators: name: Benuzzi, Fabien
Publisher: name: RIHA Journal
Year: 2014

description: Research on the European success of Venetian art during the 18th century has above all examined the activity of the painters. This paper analyzes the works of Venetian sculptors through some important case studies. Attention is given to several commissions of sculpture from Russia (among them works ordered by Peter the Great from 1719 to 1723), German states (Prussia, Saxony and Bavaria), Sweden and England. The analysis also concerns Venetian intellectuals who played the roles of mediators, such as Anton Maria Zanetti and Francesco Algarotti. The comparative study of these commissions allows us to formulate hypotheses about who were the most praised sculptors and whether there was a taste for specific artistic tendencies. It seems, for example, that British clients mainly appreciated classical sculptors like Antonio Gai and Giovanni Marchiori, in contrast to other countries, where also baroque artists were valued. The article also notes the case of Antonio Corradini, who operated for several years abroad, in Vienna and Dresden. There is finally also the attempt to outline some ideas and starting points for further research on this topic; among them an enquiry about taste for Venetian baroque sculptures in the 19th and 20th centuries.

description: We present the results of the study of the contact binary system BO CVn. We have obtained physical parameters of the components based on combined analysis of new, multi-color light curves and spectroscopic mass ratio. This is the first time the latter has been determined for this object. We derived the contact configuration for the system with a very high filling factor of about 88 percent. We were able to reproduce the observed light curve, namely the flat bottom of the secondary minimum, only if a third light has been added into the list of free parameters. The resulting third light contribution is significant, about 20-24 percent, while the absolute parameters of components are: M1=1.16, M2=0.39, R1=1.62 and R2=1.00 (in solar units). The O-C diagram shows an upward parabola which, under the conservative mass transfer assumption, would correspond to a mass transfer rate of dM/dt = 6.3 \times 10-8M\odot/yr, matter being transferred from the less massive component to the more massive one. No cyclic, short-period variations have been found in the O-C diagram (but longer-term variations remain a possibility)

description: The author interprets Susan Silas' Helmbrechts walk (1998-2003), a unique series of forty-five photographs and supplementing visual and textual materials collected during the walk along the route of two hundred and twenty-five miles. The walk repeats the route which in 1945 had to undertake women prisoners from the concentration camp in Helmbrechts near Flossenbürg in their death march to Prachatice in Czech Republic. The pictures Silas takes, the people she meets, and finally the trees, the very materiality of the road become the factors of creating her own, individual memory of the event from the past. Silas selects an object from "the margins of the Holocaust" – a forgotten event that she re-presents by reacting to contemporary objects placed along the route of the event. Silas' work offers an opportunity to critically review the concept of memory landscapes (where is memory located in a landscape?) and the phenomenon of dark tourism (is following in the footsteps of the prisoners a kind of pilgrimage, tourism, or therapy?). Silas problematises the question of memory, as well as examines different kinds of non-memory. Her camera is directed at locations that can be termed "the non-sites of memory."

Our suggestion on how to tackle this problem is to use cyclic data structures in combination with in-place bucket-sort. We present our results on the implementation of the sieve of Eratosthenes, using these ideas, which show that this approach is more robust and less affected by slow memory.

description: This document describes the initial Data Management Plan (DMP) for the HNSciCloud project. It addresses Project administration data collected as part of the execution and management of the Pre-Commercial Procurement (PCP) process within the project as well as data used as part of the scientific use cases to be deployed on the cloud services.

The DMP for the scientific use cases is based on the Guidelines on Data Management in the Horizon 2020 document version 2.0 of 30 October 2015.

These guidelines state:

“Participating projects will be required to develop a Data Management Plan (DMP), in which they will specify what data will be open.”

As such, this DMP focuses primarily on data sharing and re-use and in particular on the following issues (Annex 1 of the H2020 DMP Guidelines):

• What types of data will the project generate/collect?

• What standards will be used?

• How will this data be exploited and/or shared/made accessible for verification and re-use? If data cannot be made available, explain why.

• How will this data be curated and preserved?

description: We use a 64$h^{-1}$Mpc dark matter (DM) only cosmological simulation to examine the large scale orientation of haloes and substructures with respect the cosmic web. A web classification scheme based on the velocity shear tensor is used to assign to each halo in the simulation a web type: knot, filament, sheet or void. Using $\sim10^6$ haloes that span ~3 orders of magnitude in mass the orientation of the halo's spin and the orbital angular momentum of subhaloes with respect to the eigenvectors of the shear tensor is examined. We find that the orbital angular momentum of subhaloes tends to align with the intermediate eigenvector of the velocity shear tensor for all haloes in knots, filaments and sheets. This result indicates that the kinematics of substructures located deep within the virialized regions of a halo is determined by its infall which in turn is determined by the large scale velocity shear, a surprising result given the virilaized nature of haloes. The non-random nature of subhalo accretion is thus imprinted on the angular momentum measured at z = 0. We also find that haloes' spin axis is aligned with the third eigenvector of the velocity shear tensor in filaments and sheets: the halo spin axis points along filaments and lies in the plane of cosmic sheets.

Improving bit-vector representation of points-to sets using class hierarchy

Year: 2011
Subjects: subject: Programming Languages (cs.PL)

description: Points-to analysis is the problem of approximating run-time values of pointers statically or at compile-time. Points-to sets are used to store the approximated values of pointers during points-to analysis. Memory usage and running time limit the ability of points-to analysis to analyze large programs. To our knowledge, works which have implemented a bit-vector representation of points-to sets so far, allocates bits for each pointer without considering pointer's type. By considering the type, we are able to allocate bits only for a subset of all abstract objects which are of compatible type with the pointer's type and as a consequence improve the memory usage and running time. To achieve this goal, we number abstract objects in a way that all the abstract objects of a type and all of its sub-types be consecutive in order. Our most efficient implementation uses about 2.5 times less memory than hybrid points-to set (default points-to set in Spark) and also improves the analysis time for sufficiently large programs.

In the past, arguments favouring these various interpretations have been largely based on settlement patterns and pottery distributions. This study examines Nasca mortuary customs for evidence of hierarchical social structuring. In accordance with mortuary theory the treatment granted to an individual in death is taken as a reflection of his/her position in life. Differential treatments are seen to reflect the social structure of the society. The occupants of 213 Nasca burials are analyzed in terms of their biological age, sex, burial position, body treatment, tomb construction, tomb location, and grave goods. Pottery is given special attention as a common and less perishable form of grave inclusion. The sample is then partitioned into burial categories showing different amounts of energy expenditure. The number of these categories and the extent to which they are formally differentiated is interpreted as a reflection of vertical social structure. These findings are then compared with models of hierarchical organization in societies at differing levels of sociopolitical complexity. It is concluded that social structure, as revealed in mortuary remains, was relatively stable throughout the period under consideration. Ranking was present but there are no indications of stratification. The status system was highly graded, and formalized social ranks could not be discerned. These findings conform to patterns anticipated for chiefdom-level social formations. It is argued that Nasca represents a cultural tradition composed of several autonomous societies.

description: We present $^{12}$CO(2-1) line and 1.4 mm continuum archival observations, made with the Submillimeter Array, of the outflow HH 797 located in the IC 348 cluster in Perseus. The continuum emission is associated with a circumstellar disk surrounding the class 0 object IC 348-MMS/SMM2, a very young solar analog. The line emission, on the other hand, delineates a collimated outflow, and reveals velocity asymmetries about the flow axis over the entire length of the flow. The amplitude of velocity differences is of order 2 km s$^{-1}$ over distances of about 1000 AU, and we interpret them as evidence for jet rotation --although we also discuss alternative possibilities. A comparison with theoretical models suggests that the magnetic field lines threading the protostellar jet might be anchored to the disk of a radius of about 20 AU.

Publisher: name: Zenodo
Year: 2016
Subjects: Crack detection, wireless sensor, modal analysis, finite part model, neural networks, rotating shaft.

description: This paper presents a completely unique period crack identification technique to see the position and depth of a cross open crack on a rod. A new developed wireless sensing element capable of being mounted directly on the shaft is utilized to observe acceleration at completely different points of the shaft in an exceedingly rotating system. The vibration parameters obtained from the wireless sensors and Finite part Model give operational knowledge to perform Modal Analysis with completely different mock crack positions and depths, associated an distinctive relation between the vibration parameters and crack characteristics is developed by Neural Networks technique operating as perform approximator to predict the crack size and site on the shaft. The strategy was by experimentation valid and results have shown that the crack detection sensitivity parameters rely on the acceleration signals at completely different points of the shaft.
$W$ and $Z$ Production in the Forward Region with LHCb

description: Results for $W$ and $Z$ boson production from $pp$ collisions at $\sqrt{s} = 7$ TeV in the LHCb experiment are presented. Due to LHCb's unique forward acceptance in pseudorapidity of $2.0 \leq η\leq 4.5$ these results are a test of the Standard Model in the forward region, and can be used to better constrain parton density functions in the low $x$ kinematic regime.

description: Aiming at contributing to a better understanding of the current developments, paradoxes and ways to deal with youth political participation in Europe, the main research question of the PARTISPACE project is:

How and where do 15- to 30 year-old young people participate differently across social milieus and youth cultural scenes and across eight European cities (framed by different national welfare, education and youth policies)?

In relation to this research question, this report was intended to delineate the overall social, political, institutional and cultural framework in which the project PARTISPACE is placed and to identify the main starting points for the development of the forthcoming fieldwork.

In so doing, the report has outlined the scenario of youth participation in the eight countries involved in the PARTISPACE project.
Timing and broad band spectroscopy of 1A 1118-61 with Suzaku

description: We present a timing and broad-band pulse phase resolved spectral analysis of the transient Be X-ray binary pulsar 1A 1118-61 observed during its outburst in January 2009 using Suzaku observations. Suzaku observations were made twice, once at the peak of the outburst, and once 13 days later at its declining phase.Pulse profiles from both observations exhibit strong energy dependence with several peaks at low energies and a single peak above ~10 keV. A weak, narrow peak is detected at the main dip of the pulse profiles from both observations in the energy bands below 3 keV, indicating the presence of a phase dependent soft excess in the source continuum. The broad-band energy spectrum of the pulsar could be fitted well with a partial covering cutoff power-law model and a narrow iron fluorescence line. We also detect a broad cyclotron feature at ~50 keV from both observations which is a feature common for accretion powered pulsars with high magnetic field strengths. Pulse phase-resolved spectral analysis shows an increase in the absorption column density of the partial covering component, as well as variation in the covering fraction at the dips of the pulse profiles, that naturally explains the energy dependence of the same. The cyclotron line parameters also show significant variation with pulse phase with a ~ 10 keV variation in the cyclotron line energy and a variation in depth by a factor of three. This can be explained either as the effect of different viewing angles of the dipole field at different pulse phases, or a more complex underlying magnetic field geometry

description: Data produced by laboratory Einstein-Podolsky-Rosen-Bohm (EPRB) experiments is tested against the hypothesis that the statistics of this data is given by quantum theory of this thought experiment. Statistical evidence is presented that the experimental data, while violating Bell inequalities, does not support this hypothesis. It is shown that an event-based simulation model, providing a cause-and-effect description of real EPRB experiments at a level of detail which is not covered by quantum theory, reproduces the results of quantum theory of this thought experiment, indicating that there is no fundamental obstacle for a real EPRB experiment to produce data that can be described by quantum theory.

description: It has been shown in (Gaidashev et al, 2010) and (Gaidashev et al, 2011) that infinitely renormalizable area-preserving maps admit invariant Cantor sets with a maximal Lyapunov exponent equal to zero. Furthermore, the dynamics on these Cantor sets for any two infinitely renormalizable maps is conjugated by a transformation that extends to a differentiable function whose derivative is Holder continuous of exponent alpha>0. In this paper we investigate numerically the specific value of alpha. We also present numerical evidence that the normalized derivative cocycle with the base dynamics in the Cantor set is ergodic. Finally, we compute renormalization eigenvalues to a high accuracy to support a conjecture that the renormalization spectrum is real.
Extremal Correlator of Three Vertex Operators for Circular Winding Strings in AdS5xS5

Year: 2011
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We study a three-point correlator of the three heavy vertex operators representing the circular winding string states which are point-like in AdS_5 and rotating with two spins and two winding numbers in S^5. We restrict ourselves to the case that two of the three vertex operators are located at the same point. We evaluate semiclassically the specific three-point correlator on a stationary splitting string trajectory which is mapped to the complex plane with three punctures. It becomes an extremal and 4d conformal invariant three-point correlator on the boundary. The marginality condition of the vertex operator is discussed.

description: We combine the shear-transformation-zone (STZ) theory of amorphous plasticity with Edwards' statistical theory of granular materials to describe shear flow in a disordered system of thermalized hard spheres. The equations of motion for this system are developed within a statistical thermodynamic framework analogous to that which has been used in the analysis of molecular glasses. For hard spheres, the system volume $V$ replaces the internal energy $U$ as a function of entropy $S$ in conventional statistical mechanics. In place of the effective temperature, the compactivity $X = \partial V / \partial S$ characterizes the internal state of disorder. We derive the STZ equations of motion for a granular material accordingly, and predict the strain rate as a function of the ratio of the shear stress to the pressure for different values of a dimensionless, temperature-like variable near a jamming transition. We use a simplified version of our theory to interpret numerical simulations by Haxton, Schmiedeberg and Liu, and in this way are able to obtain useful insights about internal rate factors and relations between jamming and glass transitions.
