description: Many unstable periodic orbits of the planar circular restricted 3-body problem (PCRTBP) persist as invariant tori when a periodic forcing is added to the equations of motion. In this study, we compute tori corresponding to exterior Jupiter-Europa and interior Jupiter-Ganymede PCRTBP resonant periodic orbits in a concentric circular restricted 4-body problem (CCR4BP). Motivated by the 2:1 Laplace resonance between Europa and Ganymede's orbits, we then attempt the continuation of a Jupiter-Europa 3:4 resonant orbit from the CCR4BP into the Jupiter-Ganymede PCRTBP. We strongly believe that the resulting dynamical object is a KAM torus lying near but not on the 3:2 Jupiter-Ganymede resonance.

Growing up British in British Columbia : boys in private school, 1900-1950
Creators: name: Barman, Jean
Publisher: name: University of British Columbia
Year: 2010

description: During the years 1900-50 about fifty non-Catholic private boys' schools existed in British Columbia. Most were small private ventures, a few large incorporations. Some survived only a few years, five endure to the present day. Virtually all the schools were premised on the principles and practices of private education in Britain. Three factors coalesced to bring these schools into being. British Columbia possessed from the mid-nineteenth century a heritage of private education. While acquiescing in the necessity for common schooling for the mass of the population, some families continued to educate their own offspring privately in the province, in Britain, or elsewhere in Canada. The second circumstance behind the creation of boys' schools in British Columbia was the tremendous popularity in late-Victorian Britain of a form of class-based private education particularly amenable to replication, the "public" school and its counterpart for younger boys, the preparatory school. Thirdly, British Columbia society fundamentally altered as a consequence of the national immigration policy initiated in 1896. Over the three decades 1891-1921, about 175,000 British immigrants settled in the province, including upwards to 24,000 of suitable social background to have been supporters of private education. Boys' schools on the British model were founded by enterprising .British immigrants primarily to educate the offspring of fellow settlers. However, schools' clientele gradually extended to encompass established British Columbia families of high socio-economic status. Such families were themselves responsible for the incorporation in Vancouver in the early 1930s of the province's last major boys' school, now its largest. The significance of British Columbia's boys' schools extends beyond their clientele, which did not much surpass 7,500 over the years 1900-50. Families supporting private education were already a distinctive element in the society. Educating offspring apart from vast bulk of their contemporaries helped perpetuate that separate identity from generation to generation. Socio-economic divisions in the society were in effect consolidated and maintained from the top down.

description: A substantial part of CLOSER (Cohorts and Longitudinal Studies Enhancement Resources) is to electronically document over 100,000 questions from over 380 instruments for use in the CLOSER search platform, CLOSER Discovery (http://discovery.closer.ac.uk). Whilst carrying out the metadata ingest process, a set of 5 principles were developed and fine-tuned in order to outline and protect the overall standard by which the metadata is recorded. Due to the complexity and non-standardised format of the legacy instruments, there are situations where the entry principles conflict, and therefore one or more principle must be broken in order to follow the more significant principle(s). This poster outlines the updated principles in order of importance, and describes how the careful breaking of one or more principles can be applied in order to preserve the remaining principles and produce a standardised approach.

description: There is increasing interest in the use of diagnostic rules based on microarray data. These rules are formed by considering the expression levels of thousands of genes in tissue samples taken on patients of known classification with respect to a number of classes, representing, say, disease status or treatment strategy. As the final versions of these rules are usually based on a small subset of the available genes, there is a selection bias that has to be corrected for in the estimation of the associated error rates. We consider the problem using cross-validation. In particular, we present explicit formulae that are useful in explaining the layers of validation that have to be performed in order to avoid improperly cross-validated estimates.

Fig. 7C, D.
Material.— Five specimens (including two figured: ZPAL V.48/12, 13), partial shells, from the upper Paleocene of Fossildalen, Spitsbergen, Svalbard.
Measurements.—L, 4.5–6.9 mm; H, 3.5–4.9 mm; W, 2.1– 3.0 mm; H/L, 0.71–0.80; W/L, 0.44–0.58; n = 5.
Description. —Shell small, moderately inflated, elongate-ovate, equivalve, nearly equilateral. Surface sculptured with fine commarginal ribs. Antero-dorsal margin broadly rounded, passing into semicircular anterior margin; posterodorsal margin nearly straight, sloping gently into bluntly pointed posterior end; ventral margin broadly arcuate. Escutcheon not demarcated but broad. Beak not very prominent, slightly opisthogyrate, located centrally. Hinge with two series of very small teeth. Pallial sinus narrow, shallow, posterior muscle scar subquadrate.
Remarks. —Although we could not determine the presence of a resilifer, the available specimens are considered to belong in Neilonella because of their elongate-ovate outline, the presence of many fine commarginal ribs on the shell surface and the bluntly pointed posterior end. They resemble Neilonella alleni Amano and Jenkins, 2017, from the Selandian (middle Paleocene) Katsuhira Formation in eastern Hokkaido, Japan, in their small size and in having sculpture of fine commarginal ribs. However, the anteriorly situated and more bluntly pointed beak of N. alleni enables us to separate it from the present species.

description: Helium star - carbon-oxygen white dwarf (CO WD) binaries are potential single-degenerate progenitor systems of thermonuclear supernovae. Revisiting a set of binary evolution calculations using the stellar evolution code $\texttt{MESA}$, we refine our previous predictions about which systems can lead to a thermonuclear supernova and then characterize the properties of the helium star donor at the time of explosion. We convert these model properties to NUV/optical magnitudes assuming a blackbody spectrum and support this approach using a matched stellar atmosphere model. These models will be valuable to compare with pre-explosion imaging for future supernovae, though we emphasize the observational difficulty of detecting extremely blue companions. The pre-explosion source detected in association with SN 2012Z has been interpreted as a helium star binary containing an initially ultra-massive WD in a multi-day orbit. However, extending our binary models to initial CO WD masses of up to $1.2\,M_{\odot}$, we find that these systems undergo off-center carbon ignitions and thus are not expected to produce thermonuclear supernovae. This tension suggests that, if SN 2012Z is associated with a helium star - WD binary, then the pre-explosion optical light from the system must be significantly modified by the binary environment and/or the WD does not have a carbon-rich interior composition.

Besonders in einer Zeit, in der nukleare, biologische und chemische Abrüstung- und Rüstungskontrollmaßnahmen vor großen Herausforderungen stehen und gleichzeitig neue Technologien veränderte Anforderungen an diese Kontrollmechanismen mit sich bringen, gewinnt die naturwissenschaftlich-technische Friedensforschung enorm an Bedeutung. Sie beschäftigt sich auf der Grundlage von Erkenntnissen aus verschiedenen Naturwissenschaften und technischen Fachrichtungen (z. B. Physik, Chemie, Biologie, Informatik) mit der Rolle naturwissenschaftlicher und technischer Möglichkeiten im Kontext von Krieg und Frieden sowie Rüstung und Abrüstung. Sie unterstützt die politischen Prozesse der Kriegsprävention, der Abrüstung und der Vertrauensbildung mit Analysen der Eigenschaften und Folgen neuer Waffenarten und Technologien. Aus dieser Forschung werden Vorschläge für die Begrenzung neuer Waffenentwicklungen ebenso entwickelt wie technische Lösungen für eine verbesserte Rüstungskontrolle. Dieser Artikel benennt aktuelle Herausforderungen der naturwissenschaftlich-technischen Friedensforschung und geht dabei auch auf die aktuellen Empfehlungen des Wissenschaftsrats zur Weiterentwicklung der Friedens- und Konfliktforschung aus dem Jahr 2019 ein.

Assuming that a neutralino is the next-to-lightest SUSY particle, we present a measurement of the neutralino mass at the LHC in two photons + missing energy events, which is based on the MT2 method. It is a direct measurement of the neutralino mass itself, independent of other SUSY particle masses and patterns of cascade decays before the neutralino is produced.

The differential (and total) cross sections and various polarization observables for this reaction have been calculated in terms of the electromagnetic form factors of the corresponding $γ^*ρρ$ current. The elements of the spin--density matrix of the $ρ-$meson were also calculated. Numerical estimations have been done, with the help of phenomenological form factors obtained in the space--like region of the momentum transfer squared and analytically extended to the time-like region.

About the Designing of Antennas

Subjects: description

description: The well-known solution of Maxwell's equations has a number of shortcomings. The author has found a solution to the Maxwell equations, free from these shortcomings. In particular, a new solution of Maxwell's equations for spherical wave in the entire region of existence of the wave (without partitioning into zones, as is customary in antenna theory) has been found. The solution of this problem is known and it is on the basis of this solution that the antennas are constructed. However, this solution has a number of shortcomings. In practice, these drawbacks of the known solution mean that they (mathematical solutions) do not strictly describe the real radiation of technical devices. A more rigorous solution to this problem, when applied in antenna design systems, a) should significantly simplify the antenna design process,
 b) will allow you to obtain calculations that are minimally deviating from the results of measuring the characteristics of real antennas built according to the results of design, c) due to this, to exclude the laborious and time-consuming process of correcting the results of mathematical design. Therefore it is advisable to begin developing a new system for the automated design of antennas.

Given a set of fixed reducing pure states, we study the linear combinations of them, such that they all have the same marginal states with the given ones. We define the so called Hadamard set of quantum states whose Gram-Schmidt matrix can be diagonalized by Hadamard unitary matrices. We show that any Hadamard set can be deterministically masked by a unitary operation. We analyze the states which can be masked together with the given Hadamard set using the result about the linear combinations of fixed reducing states. Detailed examples are given to illustrate our results.

From archival data analysis, we estimate g'-, r'-, i'-, and z'-band absolute magnitudes for the nucleus of H_g=16.62+/-0.13, H_r=16.12+/-0.10, H_i=16.05+/-0.11, and H_z=15.93+/-0.08, corresponding to nucleus colors of g'-r'=0.50+/-0.16, r'-i'=0.07+/-0.15, and i'-z'=0.12+/-0.14, an equivalent V-band absolute magnitude of H_V=16.32+/-0.08, and a nucleus radius of r_n=1.6+/-0.2 km (using a V-band albedo of p_V=0.054+/-0.012). Meanwhile, we find mean near-nucleus coma colors when 248370 was active of g'-r'=0.47+/-0.03, r'-i'=0.10+/-0.04, and i'-z'=0.05+/-0.05, and similar mean dust tail colors, suggesting that no significant gas coma is present.

description: Our ignorance of the dark energy is generally described by a two-parameter equation of state. In these approaches a particular {\it ad hoc} functional form is assumed, and only two independent parameters are incorporated. We propose a model-independent, multi-parameter approach to fitting the dark energy, and show that next-generation surveys will constrain the equation of state in three or more independent redshift bins to better than 10%. Future knowledge of the dark energy will surpass two numbers (e.g., [$w_0$,$w_1$] or [$w_0$,$w_a$]), and we propose a more flexible approach to the analysis of present and future data.

description: We analyze the current of Bose particles across the tight-binding chain connected at both ends to the particles reservoirs. Unlike the standard open Bose-Hubbard model, where the presence of reservoirs is taken into account by the Lindbladians acting on the first and the last sites of the chain, we use the semi-microscopic models for the reservoirs. This allows us to address the case of arbitrary reservoir temperature. In particular, we discuss the phenomenon of the resonant transmission for nearly condensed bosons, where the current across the chain is significantly enhanced for certain values of the gate voltage.

description: We have prepared meta-atoms based on radio-frequency superconducting quantum-interference devices
(rf SQUIDs) and examined their tunability with dc magnetic field, rf current, and temperature. rf SQUIDs
are superconducting split-ring resonators in which the usual capacitance is supplemented with a Josephson
junction, which introduces strong nonlinearity in the rf properties. We find excellent agreement between
the data and a model that regards the Josephson junction as the resistively and capacitively shunted
junction. A magnetic field tunability of 80 THz=G at 12 GHz is observed, a total tunability of 56% is
achieved, and a unique electromagnetically induced transparency feature at intermediate excitation
powers is demonstrated for the first time. An rf SQUID metamaterial is shown to have qualitatively
the same behavior as a single rf SQUID with regard to dc flux and temperature tuning.

description: In recent years the discrepancy in the value of the Hubble parameter has been growing. Recently, there are works supporting the proposal that the uncertainty principles can solve the Hubble tension. Motivated by this proposal, we work with an isotropic and homogeneous FRW universe, obtain its Hamiltonian equations, and thus, the Hubble parameter through the first Friedmann equation. In the context of GUP and EUP models, the Hubble parameter is modified. Since the fingerprints of quantum gravity are imprinted on the CMB, we consider the GUP/EUP-modified Hubble parameter in the first Friedmann equation to be the one measured by the Planck collaboration which uses the CMB data. The unmodified Hubble parameter in the first Friedmann equation is considered to be the one measured by the HST group which uses the SNeIa data. Therefore, upper bounds for the dimensionless parameters of GUP and EUP are obtained.

Euler-Bernoulli beams from a symmetry standpoint-characterization of equivalent equations
Creators: name: Soh, C. Wafo
Publisher: name: arXiv
Year: 2007
Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics

description: We completely solve the equivalence problem for Euler-Bernoulli equation using Lie symmetry analysis. We show that the quotient of the symmetry Lie algebra of the Bernoulli equation by the infinite-dimensional Lie algebra spanned by solution symmetries is a representation of one of the following Lie algebras: $2A_1$, $A_1\oplus A_2$, $3A_1$, or $A_{3,3}\oplus A_1$. Each quotient symmetry Lie algebra determines an equivalence class of Euler-Bernoulli equations. Save for the generic case corresponding to arbitrary lineal mass density and flexural rigidity, we characterize the elements of each class by giving a determined set of differential equations satisfied by physical parameters (lineal mass density and flexural rigidity). For each class, we provide a simple representative and we explicitly construct transformations that maps a class member to its representative. The maximally symmetric class described by the four-dimensional quotient symmetry Lie algebra $A_{3,3}\oplus A_1$ corresponds to Euler-Bernoulli equations homeomorphic to the uniform one (constant lineal mass density and flexural rigidity) . We rigorously derive some non-trivial and non-uniform Euler-Bernoulli equations reducible to the uniform unit beam. Our models extend and emphasize the symmetry flavor of Gottlieb's iso-spectral beams (Proceedings of the Royal Society London A 413 (1987) 235-250)

description: In [AG2] we explored the question what symmetric pairs are Gelfand pairs. We introduced the notion of regular symmetric pair and conjectured that all symmetric pairs are regular. This conjecture would imply that many symmetric pairs are Gelfand pairs, and in particular that any connected symmetric pair over C is a Gelfand pair. In this paper we show that the pairs $$(GL(V),O(V)), (GL(V),U(V)), (U(V),O(V)), (O(V \oplus W),O(V) \times O(W)), (U(V \oplus W),U(V) \times U(W))$$ are regular where V and W are quadratic or hermitian spaces over arbitrary local field of characteristic zero. We deduce from that that the pairs $(GL_n(\C),O_n(\C))$ and $(O_{n+m}(\C),O_n(\C) \times O_m(\C))$ are Gelfand pairs.

description: Although the sample of exoplanets in binaries has been greatly expanded, the sample heterogeneity and observational bias are obstacles toward a clear figure of exoplanet demographics in the binary environment. To overcome the obstacles, we conduct a statistical study that focuses on S-type planetary systems detected by the Radial Velocity method. We try to account for observational biases by estimating, from available RV data, planet detection efficiencies for each individual system. Our main results are as follows: (1) Single (multiple) planetary systems are mostly found in close (wide) binaries with separation aB)100-300 AU. (2) In binaries, single and multiple-planet systems are similar in 1-D distributions of mass and period as well as eccentricity (in contrast to the "eccentricity dichotomy" found in single-star systems) but different in the 2-D period-mass diagram. Specifically, there is a rectangular-shaped gap in the period-mass diagram of single-planet systems but not for multiples. This gap also depends on binary separation and is more prominent in close binaries. (3) There is a rising upper envelope in the period-mass diagram for planets in wide binaries as well as in single stars but not in close binaries. More specifically, there is a population of massive short period planets in close binaries but almost absent in wide binaries or single stars. We suggest that enhanced planetary migration, collision, and /or ejection in close binaries could be the potential underlying explanation for these three features.

description: In this note we review the problem of time delay of photons propagating in a spacetime with a metric that explicitly depends on the energy of the particles (Gravity-Rainbow approach). We show that corrections due to this approach -- which is closely related to DSR proposal -- produce for small redshifts ($z<<1$) smaller time delays than in the generic Lorentz Invariance Violating case.

Agricultural extension agent roles in Canada and the United States
Creators: name: Yeshewalul, Ayele
Publisher: name: University of British Columbia
Year: 2010

description: Modern societies make various provisions for the education of adults engaged in agriculture. Individual adult educators involved in such educational work are known by different titles depending upon the country. How these adult educators (agricultural extension workers) perceive their role and carry it out appears to be affected by the characteristics of their employing agency and the clientele whom they serve. The purpose of this investigation is to compare the role perception and role performance of local extension workers employed by either a university or a governmental department of agriculture. Role theory was selected as the conceptual framework for this study because of its capacity to accommodate an extension worker's perceptions of expectations regarding his duties held by his employer and his clientele. The provision of agricultural extension service in Canada (government model) is primarily a responsibility of provincial Ministries of Agriculture. In comparison, the Cooperative Extension Service in the United States (university model) involves the Federal Department of Agriculture, the Land-Grant Universities, and county governments. The following aspects of extension workers and their roles were investigated: personal characteristics, professional development, attitude toward regulatory responsibilities, use of methods and sources of information, choice of methods and techniques and extension role functions. Data were obtained through a mail questionnaire completed by 69 district agriculturalists in Alberta and British Columbia, and 84 county extension agricultural agents in Idaho and Washington. The results of this research, within the limitations of the study, indicate that there were statistically significant differences between the agricultural extension workers employed in the two kinds of organizational models on most of the variables investigated. The most striking finding was the belief of the two groups that performing regulatory duties has a negative effect on extension workers' performance as extension educators. Implications and recommendations for further research are discussed.

description: We study the dipole collective oscillations in the bose-fermi mixture using a dynamical time-dependent approach, which are formulated with the time-dependent Gross-Pitaevskii equation and the Vlasov equation. We find big difference in behaviors of fermion oscillation between the time-dependent approach and usual approaches such as the random-phase approximation and the sum-rule approach. While the bose gas oscillates monotonously, the fermion oscillation shows a beat and a damping. When the amplitude is not minimal, the dipole oscillation of the fermi gas cannot be described with a simple center-of-mass motion.

description: This is the first in a series of papers on the weak lensing effect caused by clusters of galaxies in Sloan Digital Sky Survey. The photometrically selected cluster sample, known as MaxBCG, includes ~130,000 objects between redshift 0.1 and 0.3, ranging in size from small groups to massive clusters. We split the clusters into bins of richness and luminosity and stack the surface density contrast to produce mean radial profiles. The mean profiles are detected over a range of scales, from the inner halo (25 kpc/h) well into the surrounding large scale structure (30 Mpc/h), with a significance of 15 to 20 in each bin. The signal over this large range of scales is best interpreted in terms of the cluster-mass cross-correlation function. We pay careful attention to sources of systematic error, correcting for them where possible. The resulting signals are calibrated to the ~10% level, with the dominant remaining uncertainty being the redshift distribution of the background sources. We find that the profiles scale strongly with richness and luminosity. We find the signal within a given richness bin depends upon luminosity, suggesting that luminosity is more closely correlated with mass than galaxy counts. We split the samples by redshift but detect no significant evolution. The profiles are not well described by power laws. In a subsequent series of papers we invert the profiles to three-dimensional mass profiles, show that they are well fit by a halo model description, measure mass-to-light ratios and provide a cosmological interpretation.

description: We derive fidelity benchmarks for the quantum storage and teleportation of squeezed states of continuous variable systems, for input ensembles where the degree of squeezing $s$ is fixed, no information about its orientation in phase space is given, and the distribution of phase space displacements is a Gaussian. In the limit where the latter becomes flat, we prove analytically that the maximal classical achievable fidelity (which is 1/2 without squeezing, for $s=1$) is given by $\sqrt{s}/(1+s)$, vanishing when the degree of squeezing diverges. For mixed states, as well as for general distributions of displacements, we reduce the determination of the benchmarks to the solution of a finite-dimensional semidefinite program, which yields accurate, certifiable bounds thanks to a rigorous analysis of the truncation error. This approach may be easily adapted to more general ensembles of input states.

description: Two 6-t beam dumps, made of a graphite core encapsulated in a stainless steel vessel, are used to absorb the energy of the two Large Hadron Collider (LHC) intense proton beams during operation of the accelerator. Operational issues started to appear in 2015 during LHC Run 2 (2014-2018) as a consequence of the progressive increase of the LHC beam kinetic energy, necessitating technical interventions in the highly radioactive areas around the dumps. Nitrogen gas leaks appeared after highly energetic beam impacts and instrumentation measurements indicated an initially unforeseen movement of the dumps. A computer modelling analysis campaign was launched to understand the origin of these issues, including both Monte Carlo simulations to model the proton beam interaction as well as advanced thermo-mechanical analyses. The main findings were that the amount of instantaneous energy deposited in the dump vessel leads to a strong dynamic response of the whole dump and high accelerations (above 2000g). Based on these findings, an upgraded design, including a new support system and beam windows, was implemented to ensure the dumps' compatibility with the more intense beams foreseen during LHC Run 3 (2022-2025) of 539 MJ per beam. In this paper an integral overview of the operational behaviour of the dumps and the upgraded configurations are discussed.

description: The INTEGRAL observatory has been (re-)discovering new X-ray sources since the beginning of nominal operations in early 2003. These sources include X-ray binaries, Active Galactic Nuclei, cataclysmic variables, etc. Amongst the X-ray binaries, the true nature of many of these sources has remained largely elusive, though they seem to make up a population of highly absorbed high-mass X-ray binaries. One of these new sources, IGR J19140+0951, was serendipitously discovered on 2003 Mar 6 during an observation of the galactic microquasar GRS 1915+105. We observed IGR J19140+0951 with UKIRT in order to identify the infrared counterpart. Here we present the H- and K-band spectra. We determined that the companion is a B0.5-type bright supergiant in a wind-fed system, at a distance $\la$ 5 kpc.

description: The transfer of a quantum state between distant nodes in two-dimensional networks, is considered. The fidelity of state transfer is calculated as a function of the number of interactions in networks that are described by regular graphs. It is shown that perfect state transfer is achieved in a network of size N, whose structure is that of a N/2-cross polytope graph, if N is a multiple of 4. The result is reminiscent of the Babinet principle of classical optics. A quantum Babinet principle is derived, which allows for the identification of complementary graphs leading to the same fidelity of state transfer, in analogy with complementary screens providing identical diffraction patterns.

Non-Abelian adiabatic statistics and Hall viscosity in quantum Hall states and p_x+ip_y paired superfluids

description: Many trial wavefunctions for fractional quantum Hall states in a single Landau level are given by functions called conformal blocks, taken from some conformal field theory. Also, wavefunctions for certain paired states of fermions in two dimensions, such as p_x+ip_y states, reduce to such a form at long distances. Here we investigate the adiabatic transport of such many-particle trial wavefunctions using methods from two-dimensional field theory. One context for this is to calculate the statistics of widely-separated quasiholes, which has been predicted to be non-Abelian in a variety of cases. The Berry phase or matrix (holonomy) resulting from adiabatic transport around a closed loop in parameter space is the same as the effect of analytic continuation around the same loop with the particle coordinates held fixed (monodromy), provided the trial functions are orthonormal and holomorphic in the parameters so that the Berry vector potential (or connection) vanishes. We show that this is the case (up to a simple area term) for paired states (including the Moore-Read quantum Hall state), and present general conditions for it to hold for other trial states (such as the Read-Rezayi series). We argue that trial states based on a non-unitary conformal field theory do not describe a gapped topological phase, at least in many cases. By considering adiabatic variation of the aspect ratio of the torus, we calculate the Hall viscosity, a non-dissipative viscosity coefficient analogous to Hall conductivity, for paired states, Laughlin states, and more general quantum Hall states. Hall viscosity is an invariant within a topological phase, and is generally proportional to the "conformal spin density" in the ground state.
