title: Exploring Teachers' Beliefs About Teacher Research
Creators: name: Ashour, Subhi
Publisher: name: The Open University
Year: 2012

description: The purpose of this study is to explore teachers’ beliefs and conceptions about teacher research in Syrian tertiary English language teaching contexts. Questionnaires, follow-up interviews and written follow-up were used to collect the data. This research serves as an introductory study for further research on teachers’ beliefs and conceptions about research. 52 English language teachers participated in this study and the data was analysed using descriptive statistics and thematic analysis. The main themes in this study were included in the questionnaire so these were used as bedrock where relevant data from interviews and written follow-up were collated to provide a deeper and more comprehensive account of the participants’ beliefs and practices concerning research and the impact of research on their teaching practices. The findings revealed that the teachers have diverse conceptions of research. On the one hand, positivistic research was seen as the model of how research should be; however, on the other hand, a simpler version of research, called ‘informal research’, was practised instead. The research culture as captured in this study was shown to be not conducive to engagement in research due to administrative lack of support. In this regard, this study has considerable potential in the design for future research to more fully understand teachers’ beliefs and conceptions about research and their engagement/lack of engagement in research.
On the Role of Boundary Terms in the AdS/CFT Correspondence

description: We consider a scalar field theory on AdS, and show that the usual AdS/CFT prescription is unable to map to the boundary a part of the information arising from the quantization in the bulk. We propose a solution to this problem by defining the energy of the theory in the bulk through the Noether current corresponding to time displacements, and, in addition, by introducing a proper generalized AdS/CFT prescription. We also show how this extended formulation could be used to consistently describe double-trace interactions in the boundary. The formalism is illustrated by focusing on the non-minimally coupled case using Dirichlet boundary conditions.

description: We report the transverse momentum ($p_{\mathrm{T}}$) and centrality dependence of global spin alignment ($ρ_{00}$) of $K^{*0}$ vector meson at midrapidity ($|y|<0.5$) in Au + Au collisions at $\sqrt{s_{NN}}$ = 54.4 and 200~GeV with the STAR experiment at RHIC. The $K^{*0}$ results are compared to that of $ϕ$ meson. At low-$p_{\mathrm{T}}$ region and midcentral collisions, the $K^{*0}$ $ρ_{00}$ is found to be smaller than 1/3 with about 4$σ$ significance, while that of $ϕ$ meson is observed to be larger than 1/3 with about 3$σ$ significance. The $ρ_{00}$ results are compared between RHIC and LHC energies. The physics implication of our results is also discussed.

The targum (1954:Sept. 10 - 1954:Sept. 30)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1954

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: We investigate the collective excitations of $^3$He-$^4$He mixture films at zero temperature within random phase approximation and linear response theory. In low concentration region of $^3$He, a level repulsion between zero sound and third sound mode is derived, which opens the possibility to observe quantum mechanical coherence between $^3$He particle-hole pair and the condensate of $^4$He. We also investigate the $^3$He-$^4$He vertex corrections in ladder approximation and show that the third branch, the combined mode of fermionic particle-hole pair and the third sound quanta, provides a unique correction to Landau $f$ function. Some implications to the fermion-boson mixture of alkali atoms in a potential trap is discussed.

description: We have shown in a recent collaboration that the Cauchy problem for the multi-dimensional Burgers equation is well-posed when the initial data u(0) is taken in the Lebesgue space L 1 (R n), and more generally in L p (R n). We investigate here the situation where u(0) is a bounded measure instead, focusing on the case n = 2. This is motivated by the description of the asymptotic behaviour of solutions with integrable data, as t $\rightarrow$ +$\infty$. MSC2010: 35F55, 35L65. Notations. We denote $\times$ p the norm in Lebesgue L p (R n). The space of bounded measure over R m is M (R m) and its norm is denoted $\times$ M. The Dirac mass at X $\in$ R n is $δ$ X or $δ$ x=X. If $ν$ $\in$ M (R m) and $μ$ $\in$ M (R q), then $ν$ $\otimes$ $μ$ is the measure over R m+q uniquely defined by $ν$ $\otimes$ $μ$, $ψ$ = $ν$, f $μ$, g whenever $ψ$(x, y) $\not\equiv$ f (x)g(y).

description: In this work we analyse the entanglement entropy in deep inelastic scattering off protons and nuclei. It is computed based on the formalism where the partonic state at small-x is maximally entangled with proton being constituted by large number of microstates occuring with equal probabilities. We consider analytical expressions for the number of gluons, N_{gluon}, obtained from gluon saturation models for the dipole-target amplitudes within the QCD color dipole picture. In particular, the nuclear entanglement entropy per nucleon is studied. We also study the underlying uncertainties on these calculations and compare the results to similar investigations in literature.

title: Taking Bourdieu to the Movies: Understanding Cinema as a Spatial and Embodied Practice
Creators: name: Cochrane, Berry
Publisher: name: The Open University
Year: 2013

description: This thesis employs in situ research at two cinemas in London with women who attend matinees for the over-60s to think through the nature of cinema as practice. It combines interview and observation data to explore how what we do at the cinema works to co-constitute particular modes and spatialities of cinema, and coproduce films. The analysis is informed by debates in geography, film and cinema studies, and gerontology - all read through an engagement with Pierre Bourdieu’s (1977, 1990) theory of practice. Cinema is also understood as a public space with which collective identities are pre-reflexively formed among the audience members through the body, suggesting an understanding of ‘old age’ as an emergent and heterogeneous but nevertheless enduring social identity. As such, this thesis argues for an understanding of cinema as a spatial and embodied practice that constitutes and is constituted by the film on the screen, the bodies of the audience and the spaces of viewing. This emphasis on practice attempts to build on the strengths in existing literature by moving beyond decontextualised studies of both films and audiences common to much academic writing on cinema by exploring the politics of representation, theories of embodied spectatorship, and the geography of films in the moment of viewing. In doing so, the thesis suggests that we develop a ‘cinematic habitus’ across life and that this in part shapes the film we experience in the moment of practice. It suggests that the spaces of cinema - both on and off the screen - are co-constituted not just by different practices, but different practicing bodies. In the specific research context this suggests the constitution of a new space of ageing appropriate to the mode of generation enacted by participants. As such, the understanding of cinema as practice offers a methodological and theoretical contribution to existing understandings of film and audiences by acknowledging cinema’s embodied spatio-temporalities in practice. It concludes by proposing a geography of cinema that pays attention to the co-constitutive interaction between the material spaces of viewing, the film on screen and the embodied audiences.

description: We study the effects of wave function collapses in the oscillating cantilever driven adiabatic reversals (OSCAR) magnetic resonance force microscopy (MRFM) technique. The quantum dynamics of the cantilever tip (CT) and the spin is analyzed and simulated taking into account the magnetic noise on the spin. The deviation of the spin from the direction of the effective magnetic field causes a measurable shift of the frequency of the CT oscillations. We show that the experimental study of this shift can reveal the information about the average time interval between the consecutive collapses of the wave function

description: We present a modification of the relativistic phase shift method of determining the radio emission geometry from pulsar magnetospheres proposed by Gangadhara & Gupta (2001). Our modification provides a method of determining radio emission altitudes which does not depend on the viewing geometry and does not require polarization measurements. We suggest application of the method to the outer edges of averaged radio pulse profiles to identify magnetic field lines associated with the edges of the pulse and, thereby, to test the geometric method based on the measurement of the pulse width at the lowest intensity level. We show that another relativistic method proposed by Blaskiewicz et al. (1991) provides upper limits for emission altitudes associated with the outer edges of pulse profiles. A comparison of these limits with the altitudes determined with the geometric method may be used to probe the importance of rotational distortions of magnetic field and refraction effects in the pulsar magnetosphere. We provide a comprehensive discussion of the assumptions used in the relativistic methods.

description: The high pressure and high temperature phase diagram of Ta has been studied in a laser-heated diamond-anvil cell (DAC) using x-ray diffraction measurements up to 52 GPa and 3800 K. The melting was observed at nine different pressures, being the melting temperature in good agreement with previous laser-heated DAC experiments, but in contradiction with several theoretical calculations and previous piston-cylinder apparatus experiments. A small slope for the melting curve of Ta is estimated (dTm/dP = 24 K/GPa at 1 bar) and a possible explanation for this behaviour is given. Finally, a P-V-T equation of states is obtained, being the temperature dependence of the thermal expansion coefficient and the bulk modulus estimated.

(e NHE exhibited no antibacterial activity. (e DME showed higher antibacterial activity than the NDME against the different isolates. At the highest concentration of 10 mg/mL in agar diffusion, NDME produced inhibition zones ranging from 11 to 29 mm against the microorganisms while DME produced inhibition zones ranging from 20 to 40 mm with the concentration of 10 mg/mL against the microorganisms. 0.1 mg/mL of the DME produced inhibition zones ranging between 12 and 14 mm in Aeromonas hydrophila ATCC 35654 and Pseudomonas aeruginosa ATCC 15442, respectively, while none of the isolates were inhibited by the NDME at a concentration of 1 mg/mL or less. In the agar dilution assay, the MICs of the NDME and DME ranged between 0.31 and 10 mg/mL, but more isolates were inhibited at 0.31 mg/mL of DME than those in NDME. In macrobroth assay, the MICs of the NDME ranged between 0.15 and 5.0 mg/mL and the MBCs ranged between 0.63 and 5.0 mg/mL, and the MICs of the DME ranged between 0.08 and 5.0 mg/mL and the MBCs were between 0.31 and 5.0 mg/mL.(is study indicated that DME was more active with higher antibacterial activity than the NDME of this plant, and extracting the fatty portion of plant materials prior susceptibility testing would allow plant extracts to be more effective as well as justifying the use of Aframomum melegueta in traditional medicine for the treatment of bacterial infections.

description: Past studies of compact active galactic nuclei (AGNs), the dominant population at high radio frequencies, selected them using flat spectral index criteria. This biases the sample due to the steepening of AGN spectra at high radio frequencies. We improve upon this by selecting 3610 compact AGNs using their angular size information ($\sim$0.15 arcsec scale) from the Australia Telescope 20 GHz (AT20G) high-angular-resolution catalogue. We cross-match these against the Wide-field Infrared Survey Explorer All-WISE catalogue and present a catalogue with 3300 (91%) matches, 91 (3%) rejects and 219 (6%) nondetections that are excellent high redshift candidates. Of the matched compact AGNs, 92% exhibit QSO mid-infrared colours (W1-W2>0.5). Therefore, our sample of high frequency compact sources has a very high rate of identification with mid-infrared QSOs. We find counterparts for 88% of 387 compact steep-spectrum (CSS) sources in the AT20G survey, 82%$\pm$5% of which exhibit QSO mid-infrared colours and have moderate redshifts (median redshift = 0.82), while those dominated by host galaxy colours in mid-infrared have lower redshifts (median redshift = 0.13). The latter classified into late- and early-type galaxies using their mid-infrared colours shows a majority (68%$\pm$4%) have colours characteristic of late-type galaxies. Thus, we find that a larger fraction of these CSS sources are embedded in hosts with higher gas densities than average early-type galaxies. We compare mid-infrared colours of our AGNs against those reported for AGNs primarily selected using non-radio techniques. This shows that mid-infrared SED of high frequency selected compact radio AGN is comparatively less red, possibly due to contributions from their hosts.

description: This paper is concerned with the $1||\sum p_jU_j$ problem, the problem of minimizing the total processing time of tardy jobs on a single machine. This is not only a fundamental scheduling problem, but also a very important problem from a theoretical point of view as it generalizes the Subset Sum problem and is closely related to the 0/1-Knapsack problem. The problem is well-known to be NP-hard, but only in a weak sense, meaning it admits pseudo-polynomial time algorithms. The fastest known pseudo-polynomial time algorithm for the problem is the famous Lawler and Moore algorithm which runs in $O(P \cdot n)$ time, where $P$ is the total processing time of all $n$ jobs in the input. This algorithm has been developed in the late 60s, and has yet to be improved to date. In this paper we develop two new algorithms for $1||\sum p_jU_j$, each improving on Lawler and Moore's algorithm in a different scenario. Both algorithms rely on basic primitive operations between sets of integers and vectors of integers for the speedup in their running times. The second algorithm relies on fast polynomial multiplication as its main engine, while for the first algorithm we define a new "skewed" version of $(\max,\min)$-convolution which is interesting in its own right.

REMARKS
 The new lungfish tooth plate (ROM 47638) reported here preserves features unknown in the species previously known as Ceratodus tuberculatus and indicates that the species cannot be referred to an already described genus. Although insufficient material of the species is known to permit a phylogenetic analysis, it is apparent that it forms a distinct clade, and thus merits generic distinction as Retodus n. gen.

description: In this paper the new type of thermal corrections for the helium and helium-like atomic systems are introduced. These are thermal one-photon exchange between the bound electrons and nucleus as well as between the bound electrons induced by the blackbody radiation (BBR). All the derivations are given within the rigorous QED theory. It is shown that these thermal corrections are the same order in powers of $α$ (fine structure constant) as the well-known BBR-induced Stark shift but the different behaviour in temperature. The numerical results presented in this paper make possible to expect their significance for modern experiments and testing the fundamental interactions in helium.

description: More than 30 years ago, Malozemoff (Phys. Rev. B 35, 3679 (1987)) hypothesized that exchange interaction at the interface between a ferromagnet (F) and an antiferromagnet (AF) can act as an effective random field, which can profoundly affect the magnetic properties of the system. However, until now this hypothesis has not been directly experimentally tested. We utilize magnetoelectronic measurements to analyze the effective exchange fields at Permalloy/CoO interface. Our results cannot be explained in terms of quasi-uniform effective exchange fields, but are in agreement with the random-field hypothesis of Malozemoff. The presented approach opens a new route for the quantitative analysis of effective exchange fields and anisotropies in magnetic heterostructures for memory, sensing and computing applications.

description: In recent years, the Caribbean problems of declining overseas revenue from traditional export crops such as sugar, banana, and cocoa has been aggravated by another growing problem, that of the high and rising food import bill. The worsening situation has commanded the urgent attention of governments, agricultural technicians and management personnel throughout the entire CARICOM Region. Caribbean peoples and their governments are obviously concerned about the consumption patterns in each individual territory, and the CARICOM Region as a whole. Consequently, new strategies have been developed and are still being developed to cut, and even to eliminate the Food Import Bill. This paper examines an agricultural strategy which worked successfully throughout the Caribbean during the wax years 1939-1945. It details agricultural production in Trinidad and Tobago during those years and finds that before the commencement of the Great War, food imports were high and rising. During the war, imports were forced to be curtailed substantially and local food production rose considerably to a point of relative self-sufficiency. After the conclusion of the war, however, imports began to rise again, and continued as the Caribbean economies were once more firmly integrated into, and made dependent on the dominant economies of the metropoles. The paper concludes that there are several lessons to be learnt from the agricultural strategy of the war years. The greatest of these lessons is that the problem of the hi(.jh and rising Food IMport Bill is less a Caribbean agricultural and economic problem than it is a political and social one which has to be faced squarely, if the CARICOM Region is to feed itSelf adequately wfth food produced in the Caribbean. 259 "What has happened to us is that economic and social forces are sitting upon our backs and preventing us from developing in vital spheres. Where we have had an opportunity to work freely, there we have shown great distinction. Where we have not shown it, it is because we have been presented."

description: Superbubbles surrounding OB associations provide ideal laboratories to study the stellar energy feedback problem because the stellar energy input can be estimated from the observed stellar content of the OB associations and the interstellar thermal and kinetic energies of superbubbles are well-defined and easy to observe. We have used DEM L 192, also known as N 51D, to carry out a detailed case study of the energy budget in a superbubble, and we find that the expected amount of stellar mechanical energy injected into the ISM, (18+-5)x10^51 ergs, exceeds the amount of thermal and kinetic energies stored in the superbubble, (6+-2)x10^51 ergs. Clearly, a significant fraction of the stellar mechanical energy must have been converted to other forms of energy. The X-ray spectrum of the diffuse emission from DEM L 192 requires a power-law component to explain the featureless emission at 1.0-3.0 keV. The origin of this power-law component is unclear, but it may be responsible for the discrepancy between the stellar energy input and the observed interstellar energy in DEM L 192.

description: The present study attempts to examine the purpose of borrowing credit and the impact of borrowed credit on farmers' income and employment. The study was based on primary data involving personal interview of 150 randomly selected farmers (92 from marginal and 58 small size group) of two blocks (three villages from each block) in U.P. state. The data pertain to the crop year 1987-88. The result showed that the highest amount of credit was used towards buying manures and fertilizers followed by meeting irrigation charges and buying seeds. Functional analysis showed that total human labour, irrigation expenditure, operational holding, expenditure on seeds and expenditure on manures and fertilizer accounted for greater contribution to gross crop income. It emerged that credit advance to weaker sections should give emphasis on irrigation and seeds besides manures and fertilizer.

description: We present a simple criterion for solvability of lattice spin systems on the basis of the graph theory and the simplicial homology. The lattice systems satisfy algebras with graphical representations. It is shown that the null spaces of adjacency matrices of the graphs provide conserved quantities of the systems. Furthermore, when the graphs belong to a class of simplicial complexes, the Hamiltonians are found to be mapped to bilinear forms of Majorana fermions, from which the full spectra of the systems are obtained. In the latter situation, we find a relation between conserved quantities and the first homology group of the graph, and the relation enables us to interpret the conserved quantities as flux excitations of the systems. The validity of our theory is confirmed in several known solvable spin systems including the 1d transverse-field Ising chain, the 2d Kitaev honeycomb model and the 3d diamond lattice model. We also present new solvable models on a 1d tri-junction, 2d and 3d fractal lattices, and the 3d cubic lattice.

MATERIAL EXAMINED. — MI3 9/7.
STRATIGRAPHIC DISTRIBUTION. — Bed 9 of section Castello Inici, which has been assigned to the Middle Oxfordian Plicatilis Zone.
DESCRIPTION
Incomplete specimen corresponding to the body chamber of an individual that reached a diameter of about 60 mm. The shell is globular and rather involute. The whorl section is ovate, with convex flanks converging towards the narrow venter. The umbilical edge is rounded and no umbilical wall is visible. Bundles of two strong, radiate ribs spring from radial umbilical bullae. Single ribs are intercalated between the bundles.
DISCUSSION
 The poor preservation of our specimen prevents its precise identification. The morphologically closer species is Tornquistes (T.) romani. It is impossible to state if the specimen studied corresponds to an adult or to an immature individual but its rib density and, apparently, its umbilical width can be compared to immature specimens of similar diameter described by Thierry & Charpy (1982). The preservation does not allow observing whether the umbilical wall is really not developed or if it is simply not observable. Tornquistes (T.) multicostatum Thierry & Charpy, 1982 and T. (T.) helvetiae (Tornquist, 1896) have more evolute shells.

description: Spin susceptibility of stabilized δphase in the Pu-Ga alloy is studied by measuring {69,71}^Ga NMR spectra and nuclear spin-lattice relaxation rate {69}T_{1}^{-1} in the temperature range 5 - 350 K. The shift ({69}^K) of the {69,71}^Ga NMR line and {69}^T_{1}^{-1} are controlled correspondingly by the static and the fluctuating in time parts of local magnetic field arisen at nonmagnetic gallium due to transferred hyperfine coupling with the nearest f electron environment of the more magnetic Pu. The nonmonotonic with a maximum around 150 K behavior of {69}^K(T) χ_{s,5f}(T) is attributed to the peculiarities in temperature dependence of the f electron spin susceptibility χ_{s,5f}(T) in δphase of plutonium. The temperature reversibility being observed in {69}^K(T) data provides strong evidence for an electronic instability developed with T in f electron bands near the Fermi energy and accompanied with a pseudogap-like decrease of χ_{s,5f}(T) at T<150 K. The NMR data at high temperature are in favor of the mainly localized character of 5f electrons in δphase of the alloy with characteristic spin-fluctuation energy Γ(T) T^{0.35(5)}, which is close to $Γ(T) T^{0.5} predicted by Cox et al. [J. Appl. Phys. 57, 3166 (1985)] for 3D Kondo-system above T_Kondo}. The dynamic spin correlations of 5f electrons become essential to consider for {69}^T_{1}^{-1}(T) only at T<100 K. However, no NMR evidences favoring formation of the static magnetic order in δ-Pu were revealed down to 5K .

description: A significant step has been made towards understanding the physics of the transient surface current triggered by ejected electrons during the interaction of a short intense laser pulse with a high-conductivity target. Unlike the commonly discussed hypothesis of neutralization current generation as a result of the fast loss of hot electrons to the vacuum, the proposed mechanism is associated with excitation of the fast current by electric polarization due to transition radiation triggered by ejected electrons. We present a corresponding theoretical model and compare it with two simulation models using the FDTD (finite-difference time-domain) and PIC (particle-in-cell) methods. Distinctive features of the proposed theory are clearly manifested in both of these models.

title: The Catholic Church, Religion and Politics in Post-Communist Poland: Secularisation and Republicisation 1989-2007
Creators: name: Fras, Maksymilian Zbigniew
Publisher: name: The Open University

description: This thesis examines the relationship between religion and politics in post-communist Poland. Its focus is on how religion continues to maintain high salience and visibility in Polish public life despite falling individual religiosity. The study draws on theories of secularisation and republicisation, and aims to assess their applicability to the Polish case study. Based on an analysis of the relationship between religion and politics in Poland, this thesis argues that the continued public presence of religion is due to historical factors, notably the legacy of the communist era, which enabled the institutionalisation of a position of influence for the Polish Roman Catholic Church that was consolidated during the early post-communist period (1989-1993). It is the historical legacy of the Catholic Church acting as a critic of the government and a symbolic representative of the nation as well as institutional interests of both the Church and key political actors that preserve the status quo. The research material that this thesis analyses consists of Polish sources concerning the Church, religion and politics in Poland, including primary sources such as Church and government documents and press, as well as secondary sources such as academic journals and interviews with key Polish academics. The main aim of the research is to investigate the connections between the communist-era past and contemporary institutional interests and the links between religious and political groups in modern democratic Poland.
Chiral limit of 2-color QCD at strong couplings

description: We study two-color lattice QCD with massless staggered fermions in the strong coupling limit using a new and efficient cluster algorithm. We focus on the phase diagram of the model as a function of temperature $T$ and baryon chemical potential $μ$ by working on $L_t \times L^d$ lattices in both $d=2,3$. In $d=3$ we find that at $μ=0$ the ground state of the system breaks the global U(2) symmetry present in the model to U(1), while the finite temperature phase transition (with $L_t=4$) which restores the symmetry is a weak first order transition. In $d=2$ we find evidence for a novel phase transition similar to the Berezinky-Kosterlitz-Thouless phenomena. On the other hand the quantum (T=0) phase transition to a symmetric phase as a function of $μ$ is second order in both $d=2,3$ and belongs to the mean field universality class.

description: The luminosity function of Fast Radio Bursts (FRBs), defined as the event rate per unit cosmic co-moving volume per unit luminosity, may help to reveal the possible origins of FRBs and design the optimal searching strategy. With the Bayesian modelling, we measure the FRB luminosity function using 46 known FRBs. Our Bayesian framework self-consistently models the selection effects, including the survey sensitivity, the telescope beam response, and the electron distributions from Milky Way / the host galaxy / local environment of FRBs. Different from the previous companion paper, we pay attention to the FRB event rate density and model the event counts of FRB surveys based on the Poisson statistics. Assuming a Schechter luminosity function form, we infer (at the 95% confidence level) that the characteristic FRB event rate density at the upper cut-off luminosity $L^*=2.9_{-1.7}^{+11.9}\times10^{44}\,\rm erg\, s^{-1}$ is $ϕ^*=339_{-313}^{+1074}\,\rm Gpc^{-3}\, yr^{-1}$, the power-law index is $α=-1.79_{-0.35}^{+0.31}$, and the lower cut-off luminosity is $L_0\le9.1\times10^{41}\,\rm erg\, s^{-1}$. The event rate density of FRBs is found to be $3.5_{-2.4}^{+5.7}\times10^4\,\rm Gpc^{-3}\, yr^{-1}$ above $10^{42}\,\rm erg\, s^{-1}$, $5.0_{-2.3}^{+3.2}\times10^3\,\rm Gpc^{-3}\, yr^{-1}$ above $10^{43}\,\rm erg\, s^{-1}$, and $3.7_{-2.0}^{+3.5}\times10^2\,\rm Gpc^{-3}\, yr^{-1}$ above $10^{44}\,\rm erg\, s^{-1}$. As a result, we find that, for searches conducted at 1.4 GHz, the optimal diameter of single-dish radio telescopes to detect FRBs is 30-40 m. The possible astrophysical implications of the measured event rate density are also discussed in the current paper.

Transitions from small to large Fermi momenta in a one-dimensional Kondo lattice model

description: We study a one-dimensional system that consists of an electron gas coupled to a spin-1/2 chain by Kondo interaction away from half-filling. We show that zero-temperature transitions between phases with "small" and "large" Fermi momenta can be continuous. Such a continuous but Fermi-momentum-changing transition arises in the presence of spin anisotropy, from a Luttinger liquid with a small Fermi momentum to a Kondo-dimer phase with a large Fermi momentum. We have also added a frustrating next-nearest-neighbor interaction in the spin chain to show the possibility of a similar Fermi-momentum-changing transition, between the Kondo phase and a spin-Peierls phase, in the spin isotropic case. This transition, however, appears to involve a region in which the two phases coexist.
description: The updated version clarifies the definitions of small and large Fermi momenta, the role of anisotropy, and how Kondo interaction affects Luttinger liquid phase. 12 pages, 5 figures

description: Three-dimensional models of astrospheres have recently become of interest. However, comparisons between these models and observations are non-trivial because of the two-dimensional nature of observations. By projecting selected physical values of three-dimensional models of astrospheres onto the surface of a sphere that is centred on a virtual all-sky observer, these models can be compared to observational data in different observables: the column density, bremsstrahlung flux, rotation measure, H$α$ flux, and synchrotron or cyclotron flux. Projections were calculated by rotating and moving the astrosphere model to the desired position and orientation and by then computing the value of a given patch on the sphere by a modified line-of-sight integration. Contributions to the selected observable made by all model cells that are connected to the patch by the line of sight in question were taken into account. When the model produces a bow shock, a distinct parabolic structure produced by the outer astrosheath can be seen in every observable of the projection, the exact shape depending on the orientations of the line of sight and the stellar motion. Of all four examined astrosphere models, only that of $λ$ Cephei shows fluxes that are higher than current observational thresholds. This is due to the strong stellar wind and interstellar inflow of the $λ$ Cephei model.
