description: The Effective Field Theory (EFT) Lagrangian for a generic axion-like particle (ALP) has many free parameters, and leaves quite some freedom for the expected phenomenology. In this work, we set up more constrained EFTs by enforcing true axion-like properties for the ALP. Indeed, though the Peccei-Quinn symmetry of the QCD axion is anomalous, it is so in specific ways, and this shows up as consistency conditions between the gauge boson and fermion couplings. We propose to enforce such conditions, as inspired from the DFSZ and KSVZ scenarios, on the generic ALP EFTs. These truly axion-like ALP EFTs are then particularly well-suited as benchmark scenarios, to be used in the search for ALPs both at colliders and at low-energy experiments.

description: The fields of cosmic ray astrophysics, gamma-ray astrophysics, and neutrino astrophysics have diverged somewhat. But for the air showers in the GeV and TeV energy ranges, the ground-based detector techniques have considerable overlaps. VHE gamma-ray astronomy is the observational study measuring the directions, flux, energy spectra, and time variability of the sources of these gamma rays. With the low flux of gamma rays, and the background of charged particle cosmic rays, the distinguishing characteristic of gamma-ray air shower detectors is large size and significant photon to charge particle discrimination. Air shower telescopes for gamma-ray astronomy consist of an array of detectors capable of measuring the passage of particles through the array elements. To maximize signal at energies of a TeV or so, the array needs to be built at high altitude as the maximum number of shower particles is high in the atmosphere. These detectors have included sparse arrays of shower counters, dense arrays of scintillators or resistive plate counters (RPC), buried muon detectors in concert with surface detectors, or many-interaction-deep Water Cherenkov Detectors (WCD). In general these detectors are sensitive over a large field of view, the whole of the sky is a typical sensitivity and perhaps 2/3 of the sky selected for clean analysis, but with only moderate resolution in energy, typically due to shower-to-shower fluctuations and the intrinsic sampling of the detector. These telescopes though, operate continuously, despite weather, moonlight, day or night, and without needing to be pointed to a specific target for essentially a 100\% duty cycle. In this chapter we will examine the performance and characteristics of such detectors. These are contrasted with the Imaging Air Cherenkov Telescopes which also operate in this energy range, and both current and future proposed experiments are described.

description: Machine-type communication (MTC) plays a crucial role in the success of the internet of things (IoT) paradigm. It enables MTC devices (MTCDs) to communicate with each other seamlessly and efficiently, leading to improved automation, productivity, and user experience. However, the massive connections of these devices across cellular networks cause congestion and network overload due to collisions during the random access (RA) process. This results in delays, an increase in the amount of energy consumed by MTCDs, and a proportional decrease in efficiency. Several techniques, such as congestion control mechanisms and a non-orthogonal random access scheme (NORA), have been suggested to mitigate these challenges. In this paper, we propose a cluster-based NORA scheme (CNORA) as a solution to the issues of congestion and network overload. Clustering the MTCDs and utilizing NORA to limit the number of collisions that occur during the RA process allows us to achieve our goal of decreasing the total number of access requests coming from the MTCD with reduced energy consumption. Our proposed scheme shows improvements in the average access delay and RA efficiency.

description: When decreasing the size of nanoscale magnetic particles their magnetization becomes vulnerable to thermal fluctuations as approaching the superparamgnetic limit, hindering thus applications relying on a stable magnetization. Here, we show theoretically that a magnetoelectric coupling to a ferroelectric substrate renders possible the realization of substantially smaller nano clusters with thermally stable magnetization. For an estimate of cluster size we perform calculations with realistic material parameters for iron nano particles on ferroelectric BaTiO3 substrate. We find, steering the polarization of BaTiO3 with electric fields affects the magnetism of the deposited magnetic clusters. These findings point to a qualitatively new class of superparamagnetic composites.

description: Diffusion is one of the most ubiquitous transport phenomena in nature. Experimentally, it can be tracked by following point spreading in space and time. Here, we introduce a spatiotemporal pump-probe microscopy technique that exploits the residual spatial temperature profile obtained through the transient reflectivity when probe pulses arrive before pump pulses. This corresponds to an effective pump-probe time delay of 13 ns, determined by the repetition rate of our laser system (76 MHz). This pre-time-zero technique enables probing the diffusion of long-lived excitations created by previous pump pulses with nanometer accuracy, and is particularly powerful for following in-plane heat diffusion in thin films. In contrast to existing techniques for quantifying thermal transport it does not require any material input parameters or strong heating. We demonstrate the direct determination of the thermal diffusivities of the layered materials MoSe$_2$ (0.18 cm$^2$/s), WSe$_2$ (0.20 cm$^2$/s), MoS$_2$ (0.35 cm$^2$/s), and WS$_2$ (0.59 cm$^2$/s). This technique paves the way for observing novel nanoscale thermal transport phenomena and tracking diffusion of a broad range of species.

description: The cross-sections of diffractive double hadron photo- or electroproduction with large $p_T$, on a nucleon or a nucleus, are calculated to NLO accuracy. A hybrid formalism mixing collinear factorization and high energy small-$x$ factorization, more precisely the shockwave formalism for the latter, is used to derive the results. The cancellation of divergences is explicitly shown, and the finite parts of the NLO differential cross-sections are found. We work in arbitrary kinematics such that both photoproduction and leptoproduction are considered. The results are therefore usable, to detect saturation effects, at both the future EIC or already at LHC, using Ultra Peripheral Collisions.

description: We propose schemes for generating spin currents into a semiconductor by adiabatic or non-adiabatic pumping of electrons through interacting quantum dots. The appeal of such schemes lies in the possibility to tune the pumping characteristics via gate voltages that control the properties of the quantum dot. The calculations are based on a systematic perturbation expansion in the tunnel-coupling strength and the pumping frequency, expressed within a diagrammatic real-time technique. Special focus is put on the possibility of pure spin pumping, i.e., of pumping spin currents without charge currents.

description: We have considered a system consisting of two coupled quantum dots containing two electrons, i.e., two quantum dots next to each other with one excess electron each, subjected to an uniform magnetic field perpendicular to the quantum dots plane. The effect of different confinement potential profiles under which the electrons are subjected is studied. This study has been performed in the light of interest in fundamental logical quantum-gate operations: we have been concerned in analysing the behaviour of the main physical quantities which should be involved in a two-qubit quantum-gate operation for two different profiles of confinement found in literature. Our purpose was to establish how sensitive the physical quantities are to the confinement profile and in which range of magnetic field this issue can be critical.

The effects of different forms of vitamin A on intestinal health: insights from a genetic mouse model of vitamin A deficiency
Creators: name: Honarbakhsh, Maryam
Publisher: name: No Publisher Supplied
Year: 2020

description: Vitamin A deficiency (VAD) is one of the most widespread micronutrient deficiencies affecting hundreds of millions of children and pregnant women in over half of the countries worldwide, despite the implementation of numerous intervention programs. Emerging evidence suggests that VAD can impact intestinal microbiota diversity and fitness suggesting a combined effect of dietary vitamin A and status. Not only vitamin A can be obtained from food of animal origin as preformed vitamin A, but also from vegetables and fruits containing provitamin A carotenoids, mainly as βC. In fact, βC is the most abundant dietary source of vitamin A worldwide, and often the sole source of the vitamin in certain regions of the world. Yet, its impact on intestinal functions and microbiome is unknown, especially during VAD.The goal of this study was to understand the impact of different forms of dietary vitamin A (preformed retinoids or provitamin A carotenoids) vs. vitamin A status on intestinal health during VAD. To address this question, we used a genetic mouse model of VAD, the Lrat-/-Rbp-/- mice. Unable to store and deliver retinoids (vitamin A and its derivatives) to peripheral tissues, these mice display a tenuous vitamin A status. Fecal 16S rRNA gene analysis showed that VAD in our genetic model was concomitant with fecal microbial dysbiosis and dietary vitamin A did not impact the fecal microbial taxonomic profile. Also, VAD resulted in impaired structure and functions of the intestinal barrier as manifested by reduced mucins and antimicrobial defense, leaky gut, increased inflammation and oxidative stress, and impaired mucosal immunocytokine profiles. We also showed that that -carotene, as the sole source of the vitamin, not only improved the vitamin A status of the vitamin A deficient mutant mice but also improved intestinal dysfunctions and modified the taxonomic profile of the fecal microbiome of VAD.
The electron cyclotron drift instability: a comparison of particle-in-cell and continuum Vlasov simulations

description: The linear and nonlinear characteristics of the electron cyclotron drift instability (ECDI) have been studied through the particle-in-cell (PIC) and continuum Vlasov simulation methods in connection with the effects of the azimuthal length (in the $E \times B$ direction) on the simulations. Simulation results for a long azimuthal length (17.82 cm $= 627\;v_d/ω_{ce}$, where $ω_{ce}$ is the electron cyclotron frequency and $v_d$ is the $E\times B$ drift of the electrons) are reported, for which a high resolution is achieved in Fourier space. For simulations with a long azimuthal length, the linear growth rates of the PIC simulations show a considerable discrepancy with the theory, whereas the linear growth rate of the Vlasov simulations remains close to the theory. In the nonlinear regime, the inverse cascade is shown in both PIC and Vlasov simulations with a sufficiently large azimuthal length. In simulations with a short azimuthal length, however, the inverse cascade is barely observed. Instead, the PIC simulations with a short azimuthal length (0.5625 cm $=19.8\;v_d/ω_{ce}$) show an essentially continuous nonlinear dispersion, similar to what is predicted by the ion-sound turbulence theory. It is shown that, in the PIC and Vlasov simulations, the inverse cascade coincides with the formation and merging of electron structures in phase space. This process, however, terminates differently in the PIC simulations compared with the Vlasov simulations. Larger amplitudes of ECDI fluctuations are observed in the PIC simulations compared with the Vlasov simulations, leading to an intensified electron heating and anomalous current. This suggests that the statistical noise of PIC simulations might contribute to the extreme electron heating that has been observed in previous studies.

description: Subfamily Calomyscinae Vorontsov and Potapova, 1979. Zool. Zh., 58:1393. COMMENTS: Although earlier authors associated it with New World sigmodontines, Vorontsov and Potapova (1979) recognized Calomyscus's combination of distinctive features by setting it apart as a tribe in the subfamily Cricetinae of the family Cricetidae. Pavlinov (1980c) kept it with sigmodontines, and Agusti (1989:387) summarily regarded it as the only living member of the Myocricetodontinae. Carleton and Musser (1984:313) discussed the different taxonomic assignments of Calomyscus, its characteristics that did not fit with Old World hamsters (Cricetinae), and the dental similarities between Calomyscus and Miocene Democricetodon, and remarked that " Calomyscus could be justifiably classified among the cricetodontines, a group hitherto supposed extinct."

description: Structural and Optical properties of the (Na0.5 K0.5)y Li 1-y NbO3 (y = 0.934 & 0.936) ceramics have been explored in terms of the X-Ray diffraction patters, Rietveld analysis, UV-Vis spectroscopy, and Kubelka-Munk functions. Rietveld analysis of both these structures reveals them to be tetragonal with space group P4mm. It is found that increase in Li doping increases the optical band gap. Presence of additional hardening dopant MnO2 is found to have a uniform behavior for both these composition. With increasing MnO2 concentration, the band gap decreases indicative of increase in B-site cation and O-p orbitals. Different valences of the Mn ions and relative difference in the ionic radii of the Mn ions and Nb ion are most likely the reason for these optical properties.

The {\it ab initio} data thus calculated are interpolated by Gaussian process (GP) regression. The four-body potential energy surface features one $D_{2h}$ global minimum and one $C_s$ local minimum, connected by a barrierless transition state that lends insight to the reaction mechanism. This surface is intended to be of use in understanding ultracold chemistry of CaF molecules.

description: The possibility of the resilience of the beginning of inflation under unfavorable conditions is examined by considering the initial state of the inflaton field to be in the form of a relativistic gas with some of its properties in close proximity to the black body spectrum. It is demonstrated that the initial potential energy budget in such an environment is suppressed beyond the minimal value required for inflation. This is the extension of our earlier work, where we have shown that the rare regions which happen to host favorable initial conditions for the beginning of inflation could come to dominate the late-time Universe only if they started out from above the so-called self-reproduction threshold.

description: The k-core decomposition of a network has thus far mainly served as a powerful tool for the empirical study of complex networks. We now propose its explicit integration in a theoretical model. We introduce a Hard-core Random Network model that generates maximally random networks with arbitrary degree distribution and arbitrary k-core structure. We then solve exactly the bond percolation problem on the HRN model and produce fast and precise analytical estimates for the corresponding real networks. Extensive comparison with selected databases reveals that our approach performs better than existing models, while requiring less input information.

description: We present a new family of charged C-metrics in ${\cal N}=2$ gauged supergravity in four dimensions. The double Wick rotation of the C-metric allows us to bring our solution into a different family of the C-metrics previously found by Lü and Vázquez-Poritz. In the case of zero acceleration limit, our solution with vanishing charges reduces to the scalar haired black holes in AdS with regular horizons. Nevertheless, it turns out that each family of neutral solutions fails to veil the curvature singularity by the event horizon, showing that neither of them represents the accelerated black holes with a scalar hair. Physical solutions without visible curvature singularities are obtained only in the case of nonvanishing charges. Causal structures of the solution are spelled out in detail. We also present conditions under which the solution preserves supersymmetry.

description: The super-oscillation lens (SOL) can achieve super-resolution focusing but have to trade-off with weaker hotspots and higher sidebands. We propose a single compound SOL to achieve reflective confocal imaging in principle without additional lenses. The designed SOL consists of an outer lens and an inner lens which play the role of focusing lens and collective lens respectively. As a result, focusing and collecting functions can be simultaneously realized. The improved system can achieve excellent imaging performance with an ultra-high resolution (<0.34λ/NA, NA stands for numerical aperture), and almost negligible side lobe ratio and no side bands, which proved superior to conventional laser scanning confocal microscopy and single SOL. This technology can be attractive for a variety of applications in super-resolution imaging and biomedical sciences.

description: A spatially independent model that calculates the time evolution of the electron spectrum in a spherically expanding pulsar wind nebula (PWN) is presented, allowing one to make broadband predictions for the PWN's non-thermal radiation. The source spectrum of electrons injected at the termination shock of the PWN is chosen to be a broken power law. In contrast to previous PWN models of a similar nature, the source spectrum has a discontinuity in intensity at the transition between the low and high-energy components. To test the model, it is applied to the young PWN G21.5--0.9, where it is found that a discontinuous source spectrum can model the emission at all wavelengths better than a continuous one. The model is also applied to the unidentified sources HESS J1427--608 and HESS J1507--622. Parameters are derived for these two candidate nebulae that are consistent with the values predicted for other PWNe. For HESS J1427--608 a present-day magnetic field of $B\s{age}=0.4\,μ\text{G}$ is derived. As a result of the small present-day magnetic field, this source has a low synchrotron luminosity, while remaining bright at GeV/TeV energies. It is therefore possible to interpret HESS J1427--608 within the ancient PWN scenario. For the second candidate PWN HESS J1507--622, a present-day magnetic field of $B\s{age}=1.7\,μ\text{G}$ is derived. Furthermore, for this candidate PWN a scenario is favoured in the present paper in which HESS J1507--622 has been compressed by the reverse shock of the supernova remnant.
Particle Production in the Color Class Condensate: from electron-proton DIS to proton-nucleus collisions

description: We study single inclusive hadron production in proton-proton and proton-nucleus collisions in the CGC framework. The parameters in the calculation are obtained by fitting electron-proton deep inelastic scattering data. The obtained dipole-proton amplitude is generalized to dipole-nucleus scattering without any additional nuclear parameters other than the Woods-Saxon distribution. We show that it is possible to use an initial condition without an anomalous dimension and still obtain a good description of the HERA inclusive cross section and LHC single particle production measurements. We argue that one must consistently use the proton transverse area as measured by a high virtuality probe in DIS also for the single inclusive cross section in proton-proton and proton-nucleus collisions, and obtain a nuclear modification factor $R_{pA}$ that at midrapidity approaches unity at large momenta and at all energies.

description: Hybrid quantum systems seek to combine the strength of its constituents to master the fundamental conflicting requirements of quantum technology: fast and accurate systems control together with perfect shielding from the environment, including the measurements apparatus, to achieve long quantum coherence. Excellent examples for hybrid quantum systems are heterogeneous spin systems where electron spins are used for readout and control while nuclear spins are used as long-lived quantum bits. Here we show that joint initialization, projective readout and fast local and non-local gate operations are no longer conflicting requirements in those systems, even under ambient conditions. We demonstrate high-fidelity initialization of a whole spin register (99 %) and single-shot readout of multiple individual nuclear spins by using the ancillary electron spin of a nitrogen-vacancy defect in diamond. Implementation of a novel non-local gate generic to our hybrid electron-nuclear quantum register allows to prepare entangled states of three nuclear spins, with fidelities exceeding 85 %. An important tool for scalable quantum computation is quantum error correction. Combining, for the first time, optimal-control based error avoidance with error correction, we realize a three-qubit phase-flip error correction algorithm. Utilizing optimal control, all of the above algorithms achieve fidelities approaching fault tolerant quantum operation, thus paving the way to large scale integrations. Our techniques can be used to improve scaling of quantum networks relying on diamond spins, phosphorous in silicon or other spin systems like quantum dots, silicon carbide or rare earth ions in solids.

description: The Witten effect implies the electromagnetic interactions between axions and magnetic monopoles. Based on the quantum electromagnetodynamics, a generic low-energy axion-photon effective field theory was built by introducing two four-potentials ($A^μ$ and $B^μ$) to describe a photon. More anomalous axion-photon interactions and couplings ($g_{aAA}$, $g_{aBB}$ and $g_{aAB}$) arise in contrary to the ordinary axion coupling $g_{aγγ}aF^{μν}\tilde{F}_{μν}$. As a consequence, the conventional axion Maxwell equations are further modified. We properly solve the new axion-modified Maxwell equations and obtain the axion-induced electromagnetic fields given a static electric or magnetic field. It turns out that the dominant couplings $g_{aAB}$ and $g_{aBB}$ can be probed in the presence of external magnetic field and electric field, respectively. The induced oscillating magnetic fields are always suppressed compared with the electric fields for the axions with large Compton wavelengths. This is contrary to the situation in conventional experiments searching for the oscillating magnetic fields induced by sub-$μ$eV axions. Thus, we propose new strategies to measure the new couplings for sub-$μ$eV axion in haloscope experiments.

description: In the 1990s and 2000s, sensing that the critical situation had loosened with the fall of the Berlin Wall, post-Soviet aesthetics in Cuba ranged from bloodletting to bitching and from comical to grandiose. How then do women artists in Cuba deal with the contradictions, ironies, ambiguities and social negotiations in Cuban life? This paper will look at how Cuba’s artists have participated and contributed to this discourse on gender and racial politics. Now more than ever, the artistic production represents a quasi-independent space in dialogue with the State in their views of the revolutionary experience. Drawing on a variety of experimental and conceptual contemporary Cuban artists this paper shows how they have challenged accepted artistic and political discourse not only in their own society but in the global arena, reversing conventional notions of “center” and “periphery” and embodying a provocative, ironic, humorous, and omnivorously critical approach. Their work sheds light on the everyday life of Cuban women living on the Island and abroad, gender and racial politics, sexuality and power, and the discourse of global feminism in a post-Soviet context.

description: Calomyscus Thomas, 1905. Abstr. Proc. Zool. Soc. Lond., 1905(24):23. TYPE SPECIES: Calomyscus bailwardi Thomas, 1905. COMMENTS: Calomyscus has been considered monotypic (Ellerman and Morrison-Scott, 1951; Peshev, 1991). However, Vorontsov et al. (1979), in a comprehensive revision of the genus, treated most of the subspecies of C. bailwardi as distinct species, an arrangement that should be tested with additional data. The population from Syria was discovered only recently (see Peshev, 1991), indicating that the geographic ranges of living species have yet to be defined. The modern range of the genus is a remnant of a broader distribution that in the Tertiary extended as far west as Spain (see Agusti, 1989, and references therein).

description: The propagation of light in nonlinear media is well described by a $2$D nonlinear Schrödinger equation (NLSE) within the paraxial approximation, which is equivalent to the Gross-Pitaesvskii equation (GPE), the mean-field description for the dynamics of Bose-Einstein condensates (BECs). Due to this similarity, many theoretical and experimental investigations of phenomena which have already been studied and realized in BECs have been recently analysed in alternative experimental platforms such as hot atomic vapours. In this work, we study the formation of droplets of light in these media, attempting to establish a mapping between the experimental parameters normally used in BEC experiments and those needed to observe the analogous phenomenon in hot atomic vapours. We obtain the energy functional for the susceptibility of the medium in the $χ^{(3)}$ , $χ^{(3)}+χ^{(5)}$ and saturating regimes for a two-level atomic configuration considering the focusing (attractive) regime. We apply a Gaussian variational approach and check its predictions through numerical simulations of the NLSE for each regime. Finally, we study the real-time dynamics of the system for both the $χ^{(3)}+χ^{(5)}$ and saturating nonlinearities, focusing our attention on the behaviour of the breathing mode and on the analysis of droplet formation for realistic experimental conditions.

description: We study the phase diagram in the $T-μ$ plane for quark matter under the influence of a strong uniform magnetic field $\vec{B}$, in the framework of a non-local extension of the two-flavor Polyakov Nambu-Jona-Lasinio model. We analyze the deconfinement and chiral symmetry restoration transitions in the mean field approximation. For the considered parameterization, it is found that there is always a critical end point (CEP) in the $T-μ$ plane that separates a first-order transition line from a smooth crossover. The location of the CEP is studied as a function of the magnetic field.

description: We report that the finite thickness of three-dimensional topological insulator (TI) thin films produces an observable magnetoresistance (MR) in phase coherent transport in parallel magnetic fields. The MR data of Bi2Se3 and (Bi,Sb)2Te3 thin films are compared with existing theoretical models of parallel field magnetotransport. We conclude that the TI thin films bring parallel field transport into a unique regime in which the coupling of surface states to bulk and to opposite surfaces is indispensable for understanding the observed MR. The β parameter extracted from parallel field MR can in principle provide a figure of merit for searching TI compounds with more insulating bulk than existing materials.
