description: The canonical problem of the propagation of surface-plasmon-polariton (SPP) waves localized to the planar interface of a metal and a sculptured nematic thin film (SNTF) that is periodically nonhomogeneous along the direction normal to the interface was formulated. Solution of the dispersion equation obtained thereby confirmed the possibility of exciting multiple SPP waves of the same frequency or color. However, these SPP waves differ in phase speed, field structure, and the e-folding distance along the direction of propagation.

description: In this paper, we study the problem of pointwise estimation of a multivariate function. We develop a general pointwise estimation procedure that is based on selection of estimators from a large parameterized collection. An upper bound on the pointwise risk is established and it is shown that the proposed selection procedure specialized for different collections of estimators leads to minimax and adaptive minimax estimators in various settings.

description: Humans can decode emotional information from vocalizations of animals. However, little is known if these interpretations relate to the ability of humans to identify if calls were made in a rewarding or non-rewarding context. We tested whether humans could identify calls made by chickens (Gallus gallus) in these contexts, and whether demographic factors or experience with chickens affected their correct identification context and their perceived ratings of positive and negative emotions (valence) and excitement (arousal) of chickens. Participants (n = 194) listened to 8 calls when chickens were anticipating a reward, and 8 calls in non-rewarding contexts, and indicated whether the vocalizing chicken was experiencing pleasure/displeasure, and high/low excitement, using visual analogue scales. Sixty-nine % of participants correctly assigned reward and non-reward calls to their respective categories. Participants performed better at categorising reward-related calls, with 71% of reward calls classified correctly, compared with 67% of non-reward calls. Older people were less accurate in context identification. Older people's ratings of the excitement or arousal levels of reward-related calls were higher than younger people's ratings, while older people rated non-reward calls as representing higher positive emotions or pleasure (higher valence) compared to ratings made by younger people. Our study strengthens evidence that humans perceive emotions across different taxa, and that specific acoustic cues may embody a homologous signalling system among vertebrates. Importantly, humans could identify reward-related calls, and this ability could enhance the management of farmed chickens to improve their welfare.

Short pulses between 40 ns and 40 microseconds in length were produced by switching light emitting diodes with central output wavelengths of 265 nm and 257 nm, in the deep ultraviolet (or UV-C) regime, at kHz frequencies. Such photoelectron sources can be useful calibration devices for testing the properties of high-resolution electrostatic spectrometers, like the ones used in current neutrino mass searches.

description: From a sample of 20 000 p̄Xe annihilations obtained in the bubble chamber DIANA a search has been made for strange^-particle production at rest and in flight (0.4–0.9 GeV/c) taking advantage also of the unique capability of the chamber to detect neutral (photon) channels. Inclusive features such as Λ, Ks0 and Σ0 (the first time for the last particle) rates are presented, together with momentum and rapidity distributions. Semi-inclusive double^-strangeness final states ΛKX, Σ.KX and KK̄X are also presented. The observation of almost all strange channels allowed one to deduce the effective total strangeness content which turned out to be (6.2 ± 0.9)%. The K/π ratios, together with the mean multiplicities of protons, π± and π0 mesons associated or not to strangeness production are also given. The results have been compared with a modified version of the standard intranuclear cascade model obtaining, within the model uncertainties, a good agreement under the assumption that the produced hyperons have no further nuclear interaction (no elastic scattering and no sticking).
A comparative study of participants in lecture classes and participants in study discussion groups

Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this study is to analyze two distinct methods of adult education to determine if there are any significant differences between them with respect to certain selected socio-economic characteristics of the participants. The hypothesis assumes that there are no significant differences at the .01 level of confidence between adults enrolled in lecture classes and those enrolled in study-discussion groups. In the study design an effort was made to reduce the dependent variables in so far as possible so that the primary variable would be the method employed in the adult education programs. Certain programs conducted by the Extension Department of the University of British Columbia during the fall of 1961 were used in the study. These included Living Room Learning groups which used the discussion group method and certain Evening Classes which represented the class method. Three research groups were constructed consisting of those participants in evening classes, those in discussion groups, and a control group. Data was collected from participants by a questionnaire. This was analyzed and tested by the Chi Square test for statistically significant differences. The results indicate that there are statistically significant differences in certain specific characteristics of people served by different adult education methods. Differences were found in age, educational background, marital status, occupation, and previous experience in adult education programs. No significant differences were found with respect to sex, social status, social participation score, memberships in community organizations, and length of residence. In addition this study revealed that participants in university adult education are above average in socio-economic status, are actively involved in community organizations, and have lived for a relatively long period in their present community.

description: A new list of physical characteristics of 3914 astrometric radio sources, including all 717 ICRF-Ext.2 sources, observed during IVS and NRAO VCS sessions have been compiled. The list includes source type, redshift and visual magnitude (if available). In case of doubt detailed comment is provided. The list of sources with their positions was taken from the Goddard VLBI astrometric catalog with addition of two ICRF-Ext.2 sources. At this stage the source characteristics were mainly taken from the NASA/IPAC Extragalactic Database (NED). 667 sources from our list are included into the IERS list. Comparison has shown a significant difference in characteristics for about half of these 667 common sources. We compiled a list of frequently observed sources without known physical characteristics for urgent optical identification and spectrophotometric observations with large optical telescopes. This presented list of physical characteristics can be used as a supplement material for the ICRF-2, as well as a database for kinematic studies of the Universe and other related works, including scheduling of dedicated IVS programs.

description: A feasibility study has been carried out for high precision measurements of two-photon reactions leading to hadrons at the DAPHNE electron-positron collider. This new facility will operate at a CM energy of 1.02 GeV and up to a maximum of 1.5 GeV. It will have a luminosity of L⋍5x10^32 cm^-2 s^-1, 100 times larger than the present available e^+e^- colliders. DAPHNE offers an excellent opportunity to study γγ reactions at low energy with high statistics, using the KLOE detector equipped with electron tagging facilities as described in this report. Among the various topics that one may address in these studies, we concentrate on the following: (1) Precision measurements of the polarizabilities of charged and neutral pions via the two-photon reactions γγ->ππ. These will allow tests of chiral theories and chiral perturbation techniques, as well as other theoretical approaches. (2) Measurements for the first time of the azimuthal correlations of the γγ->ππ and other two-photon reactions. This provides new tests of the validity of chiral and other theories. (3) Formation of the C = +1 light pseudoscalar mesons, π^0, η and η'. This allows the study of the qq ̅ and possibly gg inner structure of these mesons. For the π^0 its measured radiative width will also improve the currently known life-time. (4) The possibility to realize a double tagging at DAPHNE will allow reliable measurements of the total γγ-> hadrons cross section below 1 GeV, which currently is vaguely known to be compared with several models. The physics program described above cannot be realized without tagging the two-photon reactions to suppress the background from e^+e^- annihilation channels and other sources.
Influence of Double-Electron Transitions on the EXAFS L Edges of Rare-Earth Systems

Publisher: name: INFN Open Access Repository
Year: 1994

description: This work presents an x-ray-absorption study at the L edges of several rare-earth compounds. In both L_1-edge and L_3edge spectra, anomalous features are clearly detected in the EXAFS region and have been associated with the creation of 2s4d and 2p4d double-core hole states, respectively. Comparison of theoretical calculations with the experiments are carried out using the results of explicit computation of cross sections for the allowed mainline (L edge) and double-electron (LN_4,5 edges) which identify the transitions expected to be observable. In addition, the excitation energies of all of these allowed transitions are given. The influence of multielectron transitions on the EXAFS data analysis is discussed for several rare-earth-based systems. An estimated of the error introduced by neglecting the presence of double-electron transitions on coordination numbers and bond distances is given, based on these experimental data.

description: The Leftover Hash Lemma states that the output of a two-universal hash function applied to an input with sufficiently high entropy is almost uniformly random. In its standard formulation, the lemma refers to a notion of randomness that is (usually implicitly) defined with respect to classical side information. Here, we prove a (strictly) more general version of the Leftover Hash Lemma that is valid even if side information is represented by the state of a quantum system. Furthermore, our result applies to arbitrary delta-almost two-universal families of hash functions. The generalized Leftover Hash Lemma has applications in cryptography, e.g., for key agreement in the presence of an adversary who is not restricted to classical information processing.

description: The Quadrantid shower, one of the most intense showers, has been observed at the beginning of January each year. However, the origin of the meteors is still unknown. It was Hasegawa (1979) who first suggested comet C/1490 Y1 to be the likely origin of the shower based on the historical records of East Asia. We analyse the records of Jo-Seon-Wang-Jo-Sil-Lok (the Annals of the Joseon Dynasty in ancient Korea) and calculate the preliminary orbital elements of comet C/1490 Y1 using a modified Gauss method. We find that comet C/1490 Y1 was a periodic one and its orbital path was very similar to that of the Quadrantid meteor stream. The determined orbital elements are perifocal passage time Tp=2265652.2983 days (7.8 Jan. 1491 in UT), perifocal distance q=0.769 AU, eccentricity e=0.747, semimajor axis a=3.04 AU, argument of the perifocus omega=164.03 degrees, longitude of ascending node Omega=283.00 degrees, and inclination i=70.22 degrees for the epoch of J2000.0. We, therefore, conclude that our result verifies the suggestion that the comet C/1490 Y1 is the origin of the Quandrantid meteor shower, but was a periodic comet. We dicuss a possible link between this comet and the asteroid 2003 EH1 as well.

description: We present for static density functional theory and time-dependent density functional theory calculations an all-electron method which employs high-order hierarchical finite element bases. Our mesh generation scheme, in which structured atomic meshes are merged to an unstructured molecular mesh, allows a highly nonuniform discretization of the space. Thus it is possible to represent the core and valence states using the same discretization scheme, i.e., no pseudopotentials or similar treatments are required. The nonuniform discretization also allows the use of large simulation cells, and therefore avoids any boundary effects.

description: A generalized WKB approach for constructing WKB series endowed with some properties of Taylor ones is presented. Apart from the Riccati equation itself its formalism involves also the Riccati-equation's derivatives (REDs) obtained by differentiating of the former with respect to a spatial variable. For any smooth potential barrier given in the finite spatial interval to include turning points, the zeroth-order term of presented WKB series is regular everywhere in this interval. Moreover, the more REDs are used, the more exact the zeroth-order solution is.

description: We present a spectral analysis of a sample of red-sequence galaxies identified by van Dokkum (2005) as dry merger remnants and ongoing dry mergers. Kinematics, stellar population absorption features, and ionisation from emission lines, are derived. We find that approximately half of the sample showing strong tidal features have younger stellar populations than a control sample at a given velocity dispersion. Conversely, galaxies with weak tidal tails and/or ongoing mergers -- with the exception of one galaxy -- do not show this young component. This seems to indicate that the young stellar populations observed in a significant fraction of ellipticals is the consequence of star formation triggered by mergers. This young component is consistent with a light "frosting" of young stars (<2% by mass) superimposed upon a dominant, old (~11 Gyr), stellar population. In terms of stellar populations, these mergers are, in fact, fairly dry. We found, however, that merger remnants with young stellar populations are supported by rotation, contrary to the expectations of a major dry merger. This suggests that the small amount of gas involved has been sufficient to produce a dynamically cold stellar component. Half of the galaxies with strong tidal distortion, however, are slow rotating and have stellar populations compatible with the control sample at a given velocity dispersion. Remarkably, none of the galaxies with velocity dispersions in excess of 250 km/s have a young stellar component, independent of the merger stage.

The model is successfully compared to both inclusive decays, such as B to J/psi X and B to D_s X, as well as exclusive ones, such as B to J/psi K^(*) and B to D^(*) D^(*)K. It also gives a good description of the momentum distribution of direct J/psi's, especially in the low-momentum region, which earlier has been claimed as a possible signal for new exotic states.

Using the Hubbard-Stratonovich transformation we calculate their effective potentials which exhibit intriguing large-N scaling behaviors. We comment on the relevance of our models to strings, membranes and also to a class of novel spin systems that are based on ternary commutation relations.

Here we report on the suppression of polarization decoherence in a ring cavity obtained by properly retooling for photonic qubits the ``bang-bang'' protection technique already employed for nuclear spins and nuclear-quadrupole qubits. Our results show that bang-bang control can be profitably extended to quantum information processes involving flying polarization qubits.

Large-N volume reduction of lattice QCD with adjoint Wilson fermions at weak-coupling
Creators: name: Bringoltz, Barak
Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Lattice (hep-lat)
subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We study the large-N volume reduction of QCD with adjoint quarks regularized on the lattice. Specifically, we use Wilson fermions, and while our d-dimensional lattice has (d-1) infinite dimensions, the remaining direction is reduced to a point. We perform a weak-coupling one-loop calculation of the free energy as a function of the holonomy in the reduced direction, and map the regimes in the bare lattice parameter space where the holonomy averages to zero and a Z_N-center symmetric configuration is the ground state. For d=4 and N_f=1/2,1 and 2 Dirac flavors we see that the center symmetry is intact in a generous regime of the phase diagram that includes the chiral point. Thus we see that large-N volume independence of lattice QCD with adjoint Wilson quarks works at weak coupling. Interestingly, we find that this is true even if the quark mass is quite large, and this opens a path to study the volume reduced large-N pure gauge theory. Finally, we analyze in detail the UV sensitivity of the one-loop potential and show that treating the reduced theory as a (d-1)-dimensional effective field theory requires the introduction of certain relevant operators that are a subset of those suggested by Unsal and Yaffe to stabilize the center symmetry. This means that different regularizations of the volume-reduced theory can be compared only if one includes these terms in the action.

QCD and Total Cross-Sections
Creators: name: R.M. Godbole
name: A. Grau
name: G. Pancheri
Publisher: name: INFN Open Access Repository
Year: 1999

description: We discuss models for total cross-sections, show their predictions for photon-photon col-lisions and compare them with the recent LEP measurements. We show that the extrapo-lations to high center of mass energies within various models differ by large factors at high energies and discuss the precision required fromfuture measurements at the proposed Linear Collider which would allow to distinguish between them.
Suppression of power-broadening in strong-coupling photoassociation in the presence of a Feshbach resonance
Creators: name: Deb, Bimalendu
name: Rakshit, Arpita
Publisher: name: arXiv
Year: 2009
Subjects: subject: Atomic Physics (physics.atom-ph)
subject: FOS: Physical sciences

description: Photoassociation (PA) spectrum in the presence of a magnetic Feshbach resonance is analyzed. Nonperturbative solution of the problem yields analytical expressions for PA linewidth and shift which are applicable for arbitrary PA laser intensity and magnetic field tuning of Feshbach Resonance. We show that by tuning magnetic field close to Fano minimum, it is possible to suppress power broadening at increased laser intensities. This occurs due to quantum interference of PA transitions from unperturbed and perturbed continuum. Line narrowing at high laser intensities is accompanied by large spectral shifts. We briefly discuss important consequences of line narrowing in cold collisions.

Radiative VPγ transitions and η–η mixing
Creators: name: A. Bramon

name: M.D. Scadron
Publisher: name: INFN Open Access Repository
Year: 2000

description: A value for the η–η’ mixing angle is extracted from the data on VPγ transitions using simple quark-model ideas. The set of data covers all possible radiative transitions between the pseudoscalar and vector meson nonets. Two main ingredients of the model are the introduction of flavour-dependent overlaps for the various q¯q wave functions and the use of the quark-flavour basis to describe the η–η’ system. In this basis the mixing angle is found to be φ_P=(37.7 ± 2.4)^◦.
Plan P - A Publishers' Offer to Institutions and Funders to Transform to Open Science

Publisher: name: Zenodo

Subjects: OpenScience, Force2021, PlanP, Transformative

description: Plan P - A Publishers’ Offer to Institutions and Funders to Transform to Open Science Plan P (http://planp.science) is JMIR Publication’s collaborative proposal for truly open scholarly communications and a framework for academic institutions and funders to facilitate a transformation towards Open Science. Plan P supports a “preprint first” publication model (PRC: Preprint - Review - Curate) by creating a platform for rapid AI-supported peer-review of preprints, editorial prospecting of preprints, and publication of curated peer-reviewed preprints in the overlay journal series JMIRx or - via a “manuscript marketplace” - in any other journal. Hashtag communities are peer-review communities, which include traditional journals but can also be other communities around a certain topical interest, can be targeted by preprint authors by using hashtags in their abstract and are being credited in published preprints. Plan P is also a business model that distributes the costs for peer-review and publication between institutions and funders. Encouragement of Registered Reports is another aspect of Plan P. Finally, Plan P creates research assessment metrics for institutions that go beyond citation-based approaches, measuring adherence to open science best practices. The ultimate goal of this endeavor is to develop the easiest path for authors to create transparent work by cataloging their entire research effort - from methodology to preliminary results and on to publication - as well as creating an environment for librarians where the needs of their budgets and institution do not conflict with their Open Science goals. Join Dr Gunther Eysenbach, founder and CEO of JMIR, as he presents this exciting plan to accelerate the move to Open Science. We would be thrilled to present to the FORCE2021 audience, given their interest in disruptive technologies and appreciation of the need for more open and equitable publishing solutions.
Analytically solvable Hamiltonians for quantum systems with a nearest neighbour interaction

Subjects: subject: Mathematical Physics (math-ph)

description: We consider quantum systems consisting of a linear chain of n harmonic oscillators coupled by a nearest neighbour interaction of the form $-q_r q_{r+1}$ ($q_r$ refers to the position of the $r$th oscillator). In principle, such systems are always numerically solvable and involve the eigenvalues of the interaction matrix. In this paper, we investigate when such a system is analytically solvable, i.e. when the eigenvalues and eigenvectors of the interaction matrix have analytically closed expressions. This is the case when the interaction matrix coincides with the Jacobi matrix of a system of discrete orthogonal polynomials. Our study of possible systems leads to three new analytically solvable Hamiltonians: with a Krawtchouk interaction, a Hahn interaction or a q-Krawtchouk interaction. For each of these cases, we give the spectrum of the Hamiltonian (in analytic form) and discuss some typical properties of the spectra.

description: In today’s competitive global business landscapes, effective project management has emerged as a critical determinant of projects and overall organizational success. With a focus on SMEs in the Kingdom of Bahrain, this study investigates the combined effects of five factors which are team communication, project mission, top management support, technical competencies, and project planning, on a project’s success. This research aims to fill a critical gap in the literature by researching these factors individually as well as collectively for SMEs in Bahrain, where SMEs make up 93% of registered enterprises and must operate under limited resource constraints.A conceptual framework is made, and data collection was done by distributing a survey with responses from 261 professionals including project managers, team leaders, team members, and stakeholders across a variety of SMEs and industries in Bahrain. The quantitative data was further analyzed and results show that all five factors are significant in determining project success, with project planning being the strongest predictor followed by project mission and team communication. Moreover, the study highlights the key benefits of a structured planning approach, aligning the project goals, good communication, technical expertise, presence of appropriate leadership support in project success.Theoretical contributions are made to the growing literature on project management, and practical recommendations are provided on how to enhance project practices in SMEs. It also offers practitioners actionable guidance in terms of robust planning, strategic commitment from leadership, and improved communications needed to deliver projects successfully. This study aims to bridge the gap between theory and practice and it offers a foundational resource for improving project management excellence in Bahrain.

description: The insoluble powder recovered at the bottom of our electrolytic cell, after several electrolytic deuterium loading/deloading cycles, was analysed by an ICP-MS analyser. The electrolyte was constituted of a deuterated hydro-alcoholic solution; Sr and Hg salts were added to such a solution at micromolar concentration; the cathode was a long and thin Pd wire. The ICP-MS analyses of the insoluble powder were motivated from the recent results of Y. Iwamura and collaborators at Mitsubishi Heavy Industries-Researh Center (Yokohama, Japan) showing reproducible "transmutation" of Sr into Mo (isotopic composition different from natural one) and Cs into Pr, when a special multilayer Pd sheet was subjected to a prolonged Deuterium gas flowing. Some of our results look partially in agreement with Y. Iwamura report. Other unexpected elements were also detected with an isotopic distribution close to the natural one. The production of stable isotopes by Selective Channel Photofission, according to the model of A.Takahashi (Osaka University, Japan), can help for understanding. Further works, hopefully also from other Laboratories, are needed to clarify this kind of results.

description: A new list of physical characteristics of 4261 astrometric radio sources, including all 717 ICRF-Ext.2 sources has been compiled. Comparison of our data of optical characteristics with the official International Earth Rotation and Reference Systems Service (IERS) list showed significant discrepancies for about half of 667 common sources. We also found that asymmetry in the radio sources distribution between hemispheres could cause significant correlation between the vector spherical harmonics, especially if the case of sparse distribution of the sources with high redshift. We identified radio sources having many-year observation history and lack redshift. This sources should be urgently observed at large optical telescopes. The list of optical characteristics created in this paper is recommended for use as a supplement material for the next International Celestial Reference Frame (ICRF) realization. It can be also effectively used for cosmological studies and planning of observing programs both in radio and optics.

description: In this work we analyze a sample of AGN spectra, selected from the 6th Data Release of the Sloan Digital Sky Survey, exploiting a generalized technique of line profile analysis, designed to take into account the whole profiles of their broad emission lines. We find that the line profile broadening functions result from a complex structure, but we may be able to infer some constraints about the role of the geometrical factor, thus improving our ability to estimate AGN properties and their relation with the host galaxy. Our results suggest that flattening and inclination within the structure of the Broad Line Region (BLR) must be taken into account. We detect low inclinations of the BLR motion plane with respect to our line of sight, typically i < 20 degrees, with a geometrical effect which generally decreases as the line profile becomes broader.
