description: The Cherenkov Telescope Array (CTA) is about to enter construction phase and one of its main key science projects is to perform an unbiased survey in search of extragalactic sources. We make use of both the latest blazar gamma--ray luminosity function and spectral energy distribution to derive the expected number of detectable sources for both the planned Northern and Southern arrays of the CTA observatory. We find that a shallow, wide survey of about 0.5 hour per field of view would lead to the highest number of blazar detections. Furthermore, we investigate the effect of axion-like particles and secondary gamma rays from propagating cosmic rays on the source count distribution, since these processes predict different spectral shape from standard extragalactic background light attenuation. We can generally expect more distant objects in the secondary gamma-ray scenario, while axion-like particles do not significantly alter the expected distribution. Yet, we find that, these results strongly depend on the assumed magnetic field strength during the propagation. We also provide source count predictions for the High Altitude Water Cherenkov observatory (HAWC), the Large High Altitude Air Shower Observatory (LHAASO) and a novel proposal of a hybrid detector.

description: The correspondence claimed by M. Douglas, between the multicritical regimes of the two-matrix model and 2D gravity coupled to (p,q) rational matter field, is worked out explicitly. We found the minimal (p,q) multicritical potentials U(X) and V(Y) which are polynomials of degree p and q, correspondingly. The loop averages W(X) and \tilde W(Y) are shown to satisfy the Heisenberg relations {W,X} =1 and {\tilde W,Y}=1 and essentially coincide with the canonical momenta P and Q. The operators X and Y create the two kinds of boundaries in the (p,q) model related by the duality (p,q) - (q,p). Finally, we present a closed expression for the two two-loop correlators and interpret its scaling limit.

description: A practical technique for determining the length of a silicon nanowire (SiNW) array is reported by the analysis of reflected images from a smartphone camera. The SiNW array was prepared by electroless chemical etching and its length controlled by the etching time of a Si wafer. The average lengths for the SiNW array were characterized by scanning electron microscopy. The relationship between the reflection spectrum and the length of the SiNW array was investigated. The ratio of percent reflectance from 900 to 550 nm exponentially increased from 1.8 ± 0.1 to 22.2 ± 1.3 when the average length increased from 184 ± 12 to 1237 ± 23 nm. Optical sensing for characterization of the length of SiNW was further developed into a simple and practical technique using a smartphone camera as a detector. A 3D printed tool was assembled to the smartphone to control the light path and the reflected image of the SiNW array was acquired. The reflected intensity ratio obtained from the reflected images with long pass to short pass filters increased analogously to the spectroscopic results. This optical-sensing-based smartphone showed simple and rapid detection for determining the lengths of a SiNW array and a SiNW array coated with a polymer film. This platform is compact and capable of on-site detecting and is promising for the characterization of reflective materials.
The Effects of Dust on the Spectral Energy Distributions of Star-Forming Galaxies

description: I review the effects of dust, both in absorption and in emission, on the spectral energy distributions (SEDs) of Local star-forming galaxies. The energy balance between the stellar light absorbed by dust at UV-optical-nearIR wavelengths and the energy re-emitted by dust in the far infrared (FIR) shows that the amount of dust extinction affecting the galaxy can be predicted with simple prescriptions applied to the UV-optical data. The implications of these results for high redshift galaxies are discussed. Arguments can be given to support the view that Local starbursts are representative of high-redshift (z>2), UV-detected, star-forming galaxies. If this is the case, the high redshift FIR emission will be generally undetected in sub-mm surveys, unless (1) the bolometric luminosity of the high-z galaxies is comparable to or larger than that of Local ultraluminous FIR galaxies and (2) their FIR SED contains a cool dust component.

description: The temperature dependences of the conductivity σ(T) for strongly interacting 2D electron system in silicon have been analyzed both in zero magnetic field and in spin-polarizing magnetic field of 14.2T, parallel to the sample plane. Measurements were carried out in a wide temperature range (1.4-9)K, in the ballistic regime of electron-electron interaction, i.e., for Tτ> 1. In zero magnetic field, the data obtained for σ(T) are quantitatively described by the theory of interaction corrections. In the fully spin-polarized state, the measured σ(T) dependences are nonlinear and even nonmonotonic for the same temperature range, where the σ(T) dependences are monotonic in the absence of the field. Nevertheless, the low-temperature parts of the experimental σ(T) dependences are linear and are qualitatively consistent with the calculated interaction corrections.

description: A long time ago, Brochard and de Gennes predicted the possibility of significantly decreasing the critical magnetic field of the Fredericksz transition (the magnetic Fredericksz threshold) in a mixture of nematic liquid crystals and ferromagnetic particles, the so-called ferronematics. This phenomenon has rarely been measured, usually due to soft homeotropic anchoring induced at the nanoparticle surface. Here we present an optical study of the magnetic Fredericksz transition combined with a light scattering study of the classical nematic liquid crystal, 5CB, doped with 6 nm diameter magnetic and non-magnetic nanoparticles. Surprisingly, for both nanoparticles, we observe at room temperature a net decrease of the threshold field of the Fredericksz transition at low nanoparticle concentrations, which appears associated with a coating of the nanoparticles by a brush of polydimethylsiloxane copolymer chains inducing planar anchoring of the director on the nanoparticle surface. Moreover the magnetic Fredericksz threshold exhibits non-monotonic behaviour as a function of the nanoparticle concentration for both types of nanoparticles, first decreasing down to a value from 23\% to 31\% below that of pure 5CB, then increasing with a further increase of nanoparticle concentration. This is interpreted as an aggregation starting at around 0.02 weight fraction that consumes more isolated nanoparticles than those introduced when the concentration is increased above $c = 0.05$ weight fraction (volume fraction $3.5 \times 10^{-2}$). This shows the larger effect of isolated nanoparticles on the threshold with respect to aggregates. From dynamic light scattering measurements we deduced that, if the decrease of the magnetic threshold when the nanoparticle concentration increases is similar for both kinds of nanoparticles, the origin of this decrease is different for magnetic and non-magnetic nanoparticles. For non-magnetic nanoparticles, the behavior may be associated with a decrease of the elastic constant due to weak planar anchoring. For magnetic nanoparticles there are non-negligible local magnetic interactions between liquid crystal molecules and magnetic nanoparticles, leading to an increase of the average order parameter. This magnetic interaction thus favors an easier liquid crystal director rotation in the presence of external magnetic field, able to reorient the magnetic moments of the nanoparticles along with the molecules.
Broad-Band Spectral Energy Distributions of Active Galactic Nuclei from an Accretion Disk with Advective Coronal Flow

description: We construct a disk-corona model which accounts for the optical-to-X-ray spectral properties of Seyfert nuclei and QSOs. We study emission spectrum emerging from a vertical disk-corona structure composed of two-temperature plasma by solving hydrostatic equilibrium and radiative transfer self-consistently. A fraction $f$ of viscous heating is assumed to be dissipated in a corona with a Thomson optical depth of $τ_c$, where advective cooling is also included, and a remaining fraction, $1-f$, dissipates within a main body of the disk. Our model can nicely reproduce the soft X-ray excess with a power-law shape and the hard tail extending to $\sim$ 50 keV. The different spectral slopes ($α\sim$ 1.5 below 2keV and $\sim$ 0.5 above, where $\Fnu \propto ν^{- α}$) are the results of different emission mechanisms and different sites; the former slope is due to unsaturated Comptonization from the innermost zone and the latter is due to a combination of the Comptonization, bremsstrahlung and a reflection of the coronal radiation at the disk-corona boundary from the inner to surrounding zone ($\leq$ 300 Schwarzschild radii). The emergent optical spectrum is redder ($α\sim 0.3$) than that of the standard disk ($α\sim -0.3$), being consistent with observations, due to the different efficiencies of spectral distortion of disk emission at different radii. Further, we find that the cut-off frequency of the hard X-ray ($\sim$ coronal electron temperature) and broad-band spectral shape are insensitive to the black-hole mass, while the peak frequency of the big blue bump is sensitive to the mass as the peak frequency $\propto \Mbh^{-1/4}$.

description: Following the detection of the GW170817 signal and its associated electromagnetic emissions, we discuss the prospects of the local Hubble parameter measurement using double neutron stars (DNSs). The kilonova emissions of GW170817 are genuinely unique in terms of the rapid evolution of color and magnitude and we expect that, for a good fraction $\gtrsim 50\%$ of the DNS events within $\sim 200$Mpc, we could identify their host galaxies, using their kilonovae. At present, the estimated DNS merger rate $(1.5^{+3.2}_{-1.2})\times 10^{-6} {\rm Mpc^{-3} yr^{-1}}$ has a large uncertainty. But, if it is at the high end, we could measure the local Hubble parameter $H_L$ with the level of $ΔH_L/H_L\sim 0.042$ ($1σ$ level), after the third observational run (O3). This accuracy is four times better than that obtained from GW170817 alone, and we will be able to examine the Hubble tension at $2.1σ$ level.

Raman Scattering Characterization and Electron Phonon Coupling Strength for MeV implanted InP(111)

description: Structural modifications in InP(111) due to 1.5 MeV implantation of Sb have been characterized using first order and second order Raman spectroscopy. With both Longitudinal Optical (LO) and Transverse Optical (TO) modes allowed for InP(111), we have investigated the evolution of both these modes as a function of fluence. Intensity, linewidth and shifts of the phonons, for both first order and second order Raman modes, display the increase in damage in the lattice with increasing fluence. The results suggest that the presence of a charge layer in the vicinity of the surface may be effecting the first order Raman data. A LO phonon-plasmon coupled mode, due to the charge layer, has also been observed that becomes sharper and more intense with increasing fluence. Results also show the presence of tensile stress along with the coexistence of crystalline InP regions and amorphous zones in the lattice. Consequently phonon confinement is observed. Phonon Confinement model (PCM) has been applied here to estimate the coherence length and the size of nano-crystalline zones in InP lattice after implantation. A crystalline/ amorphous (c/a) phase transition is observed at the fluence of $1\times10^{14} ions/cm^{2}$. The electron-phonon coupling strength has been measured by utilizing the second order Raman modes. This coupling strength is seen to decrease as the nano-crystalline zones, in the implanted lattice, become smaller.

description: Near-infrared spectroscopy has been employed for determination of biochemicals in agricultural products. In this study, a prototype near infrared instrument is reported capable of simultaneously determining primary and secondary biochemical compounds in agricultural products using supervised modeling method. Maize flour was used as the material for model development. Calibration models were developed for four primary components (moisture, protein, oil, carbohydrate) and eight secondary compounds (amylose, amylopectin, oleic acid, linoleic acid, tocopherol, carotenoid, lysine, and tryptophan). Support vector machine, which is a supervised modeling method, was utilized to develop models. The graphical user interface of the prototype was developed using the R platform, which provides the user with flexible options for analysis and data management. The results obtained from the models generated with the prototype were compared those obtained from a bench-top near infrared reflectance instrument and reference analyses. The developed prototype was able to make measurements between 900 and 2100 nm with 6 nm resolution and completed each measurement in 60 s. The prototype demonstrated adequate performance in terms of repeatability and yielded comparable results with the bench-top instrument. The best calibration model for the prototype was obtained for carotenoids. This prototype is suitable for the determination of biochemicals in additional products after appropriate prediction models are prepared.

Gauge covariance and the fermion-photon vertex in three- and four- dimensional, massless quantum electrodynamics

description: In the quenched approximation, the gauge covariance properties of three vertex Ansätze in the Schwinger-Dyson equation for the fermion self energy are analysed in three- and four- dimensional quantum electrodynamics. Based on the Cornwall-Jackiw-Tomboulis effective action, it is inferred that the spectral representation used for the vertex in the gauge technique cannot support dynamical chiral symmetry breaking. A criterion for establishing whether a given Ansatz can confer gauge covariance upon the Schwinger-Dyson equation is presented and the Curtis and Pennington Ansatz is shown to satisfy this constraint. We obtain an analytic solution of the Schwinger-Dyson equation for quenched, massless three-dimensional quantum electrodynamics for arbitrary values of the gauge parameter in the absence of dynamical chiral symmetry breaking.

We introduce a novel procedure of merging two "parent" solutions to an improved "child" solution by detecting, extracting, and combining correctly assembled puzzle segments. The solver proposed exhibits state-of-the-art performance solving previously attempted puzzles faster and far more accurately, and also puzzles of size never before attempted. Other contributions include the creation of a benchmark of large images, previously unavailable. We share the data sets and all of our results for future testing and comparative evaluation of jigsaw puzzle solvers.

description: In bulk n-GaAs epilayers doped near the metal-insulator transition, we study the evolution of electron spin lifetime $τ_s$ as a function of applied lateral electrical bias $E_x$. $τ_s$ is measured via the Hanle effect using magneto-optical Kerr rotation. At low temperatures (T<10 K, where electrons are partially localized and $τ_s > 100$ ns at zero bias), a marked collapse of $τ_s$ is observed when $E_x$ exceeds the donor impact ionization threshold at $\sim$10 V/cm. A steep increase in the concentration of warm delocalized electrons -- subject to Dyakonov-Perel spin relaxation -- accounts for the rapid collapse of $τ_s$, and strongly influences electron spin transport in this regime.

description: Images recorded through J, H, K, 2.2 micron continuum and CO filters have been obtained of a sample of metal-poor ([Fe/H] < -1.3) globular clusters in the inner spheroid of the Galaxy. The shape and color of the upper giant branch on the (K, J-K) CMD, combined with the K brightness of the RGB-tip, are used to estimate the metallicity, reddening, and distance of each cluster. CO indices are used to identify bulge stars, which will bias metallicity and distance estimates if not removed from the data. Bulge fields were also observed near each cluster. The slope of the bulge giant branch luminosity function does not vary between most fields, although the LFs in Baade's Window and near NGC 6273 are significantly shallower than average. The data also suggest that the HB content may not be uniform throughout the bulge, in the sense that a larger than average number of red HB stars may occur in fields closest to the Galactic Center.

3D Reconstruction with Low Resolution, Small Baseline and High Radial Distortion Stereo Images

description: In this paper we analyze and compare approaches for 3D reconstruction from low-resolution (250x250), high radial distortion stereo images, which are acquired with small baseline (approximately 1mm). These images are acquired with the system NanEye Stereo manufactured by CMOSIS/AWAIBA. These stereo cameras have also small apertures, which means that high levels of illumination are required. The goal was to develop an approach yielding accurate reconstructions, with a low computational cost, i.e., avoiding non-linear numerical optimization algorithms. In particular we focused on the analysis and comparison of radial distortion models. To perform the analysis and comparison, we defined a baseline method based on available software and methods, such as the Bouguet toolbox [2] or the Computer Vision Toolbox from Matlab. The approaches tested were based on the use of the polynomial model of radial distortion, and on the application of the division model. The issue of the center of distortion was also addressed within the framework of the application of the division model. We concluded that the division model with a single radial distortion parameter has limitations.

description: We study the integral representation for the exact solution to nonperturbative $c le 1$ string theory. A generic solution is determined by two functions $W(x)$ and $Q(x)$ which behaive at infinity like $x^p$ and $x^q$ respectively. The integral model for arbitrary $(p,q)$ models is derived which explicitely demonstrates $p-q$ duality of minimal models coupled to gravity. We discuss also the exact solutions to string equation and reduction condition and present several explicit examples.

description: This study explores the topic of whether or not library catalogues are meeting the needs of differentuser groups. This was narrowed down to focus on early childhood teaching students at the Universityof Canterbury and how they select picture books using the University's library catalogue. In doingso it identifies what metadata this group look for when selecting an item and found that these arenot reflected in the current catalogue. This took a qualitative approach which combined structuredinterviews with the verbal protocol analysis method in a three-part approach. Participants wereasked a series of questions during the first and second parts, then asked to think out loud as theyselecting items during the second stage. Throughout this process no prompts were provided fromthe researcher in an attempt to capture their natural thoughts. Data collected showed that earlychildhood teaching students have specific needs when selecting picture books which impacts the typeof metadata they are drawn to. These are a result for the need to find books which entertain andengage young children while aligning with the New Zealand Early Childhood Curriculum. It was foundthat these needs were not reflected in current picture book records at the University of Canterburywhich creates challenges when selecting items. Understanding the behavior of this user group canhelp to inform cataloguers at the University of Canterbury to create or edit records to improve theselection process. On a wider level, there is the potential to explore this topic in future studies tosupport libraries in creating systems which reflect the needs of their users.ING_

description: We present an investigation into the intrinsic magnetic properties of the compounds YCo5 and GdCo5, members of the RETM5 class of permanent magnets (RE = rare earth, TM = transition metal). Focusing on Y and Gd provides direct insight into both the TM magnetization and RE-TM interactions without the complication of strong crystal field effects. We synthesize single crystals of YCo5 and GdCo5 using the optical floating zone technique and measure the magnetization from liquid helium temperatures up to 800 K. These measurements are interpreted through calculations based on a Green's function formulation of density-functional theory, treating the thermal disorder of the local magnetic moments within the coherent potential approximation. The rise in the magnetization of GdCo5 with temperature is shown to arise from a faster disordering of the Gd magnetic moments compared to the antiferromagnetically aligned Co sublattice. We use the calculations to analyze the different Curie temperatures of the compounds and also compare the molecular (Weiss) fields at the RE site with previously published neutron scattering experiments. To gain further insight into the RE-TM interactions, we perform substitutional doping on the TM site, studying the compounds RECo4.5Ni0.5, RECo4Ni, and RECo4.5Fe0.5. Both our calculations and experiments on powdered samples find an increased/decreased magnetization with Fe/Ni doping, respectively. The calculations further reveal a pronounced dependence on the location of the dopant atoms of both the Curie temperatures and the Weiss field at the RE site.

description: The Atacama Millimeter/submillimeter Array (ALMA) Phasing Project (APP) has developed and deployed the hardware and software necessary to coherently sum the signals of individual ALMA antennas and record the aggregate sum in Very Long Baseline Interferometry (VLBI) Data Exchange Format. These beamforming capabilities allow the ALMA array to collectively function as the equivalent of a single large aperture and participate in global VLBI arrays. The inclusion of phased ALMA in current VLBI networks operating at (sub)millimeter wavelengths provides an order of magnitude improvement in sensitivity, as well as enhancements in u-v coverage and north-south angular resolution. The availability of a phased ALMA enables a wide range of new ultra-high angular resolution science applications, including the resolution of supermassive black holes on event horizon scales and studies of the launch and collimation of astrophysical jets. It also provides a high-sensitivity aperture that may be used for investigations such as pulsar searches at high frequencies. This paper provides an overview of the ALMA Phasing System design, implementation, and performance characteristics.

description: A nonlinear interaction between photons is observed in a process that involves charge sources. To observe this process in a vacuum, there are a growing number of theoretical and experimental studies. This process may contain exotic contribution from new physics beyond the Standard Model of particle physics, and is probed by experiments using a high-power laser or a high-field magnet, and more recently using an X-ray Free-Electron Laser (XFEL). Here, we review the present status of our experiments testing various vacuum processes. We describe four experiments with a focus on those using an XFEL: (i) photon-photon scattering in the x-ray region, (ii) laser-induced birefringence and diffraction of x rays, (iii) vacuum birefringence induced by a high-field magnet, and (iv) a dedicated search for axion-like particles using the magnet and x rays.

description: The benefits of reading for the general population, and the benefits of reading in reducing the incidenceof dementia, have been the subject of research. However, there has been very little researchdone on the benefits of reading appropriate works for those living with dementia. This discussion paperoutlines the experience of one community in New Zealand, Nelson, in setting up and running a dementia-friendly book group in the public library, and describes the benefits and limitations of this project.A particular set of classical texts was used for these book groups. These were selected and adapted asa result of an earlier feasibility study on the value of book groups for people living with dementia. Thefeasibility study (Rimkeit & Claridge, 2017) indicated that participants enjoyed the book groups, butpreferred adaptations where the original texts were shortened, but the original lexis and syntax wereretained.Both the Nelson Public Libraries experience and the feasibility study suggest the book group reading,whether in libraries or residential care facilities, can be enjoyable for people living with dementia,and it is hoped that other libraries in New Zealand will join the discussion on how best to make publiclibraries dementia-friendly, to vitally support this group of citizens to enjoy a good read.This paper invites librarians and appropriate academics to become involved in a multicentre study ofdementia-friendly book groups in New Zealand, Australia, the UK and the US, with an internationalconsortium of universities now interested, using quantitative and qualitative research to investigatethe benefits of reading for those living with dementia.

description: We analyse the emergence of Kovacs-like memory effects in athermal systems within the linear response regime. This is done by starting from both the master equation for the probability distribution and the equations for the physically relevant moments. The general results are applied to a general class of models with conserved momentum and non-conserved energy. Our theoretical predictions, obtained within the first Sonine approximation, show an excellent agreement with the numerical results.
