description: We investigate the triggering mechanism and the structural properties of obscured luminous active galactic nuclei from a detailed study of the rest-frame $B$ and $I$ HST images of 29 nearby ($z\approx 0.04-0.4$) optically selected type 2 quasars. Morphological classification reveals that only a minority (34%) of the hosts are mergers or interacting galaxies. More than half (55%) of the hosts contain regular disks, and a substantial fraction (38%), in fact, are disk-dominated ($B/T\lesssim 0.2$) late-type galaxies with low Sersic indices ($n < 2$), which is characteristic of pseudo bulges. The prevalence of bars in the spiral host galaxies may be sufficient to supply the modest fuel requirements needed to power the nuclear activity in these systems. Nuclear star formation seems to be ubiquitous in the central regions, leading to positive color gradients within the bulges and enhancements in the central surface brightness of most systems.

description: This article reviews some effects of disorder in percolation systems even away from the critical density p_c. For densities below p_c, the statistics of large clusters defines the animals problem. Its relation to the directed animals problem and the Lee-Yang edge singularity problem is described. Rare compact clusters give rise to Griffiths singuraties in the free energy of diluted ferromagnets, and lead to a very slow relaxation of magnetization. In biassed diffusion on percolation clusters, trapping in dead-end branches leads to asymptotic drift velocity becoming zero for strong bias, and very slow relaxation of velocity near the critical bias field.

description: The intestinal epithelium is organized into crypt-villus structures, which support compartmentalized functions such as nutrient absorption and barrier integrity through tightly regulated processes of proliferation, migration, differentiation, and extrusion. The tissue is subjected to mechanical inputs, including shear stress and substrate stiffness, yet the influence of these on epithelial homeostasis and force distribution along the crypt-villus axis remains poorly understood. While in vivo studies offer insights, the complexity of the intestinal environment necessitates robust in vitro models to probe these interactions under controlled conditions. To address this, we developed an in-silico model to simulate the shear stress distribution along the epithelium and the mechanical role of mucus in protecting the epithelium. Our results indicated an increasing shear stress profile from crypt to villus. Building on this, we engineered a perfusable epithelium-on-a-chip platform featuring stiffness-tuned polyacrylamide gels and open-lumen organoid monolayers. The system recapitulates the crypt-villus architecture, permits direct access to the apical surface, and enables precise shear stress modulation. Our experiments demonstrated that shear stress selectively enhances crypt density and extrusion rates while maintaining traction forces and division rates, approaching a homeostatic cell turnover balance. Beyond its immediate findings, this platform offers a versatile tool for exploring epithelial biology, enabling the study of microbial interactions, drug delivery, and disease pathology in physiologically relevant conditions. By bridging the gap between static in vitro systems and the complexity of in vivo tissues, this work provides a foundation for future advances in modelling intestinal systems with precise environmental control.

description: The effect of boundaries on the force distributions in granular media is illustrated by simulations of 2D packings of frictionless, Hertzian spheres. To elucidate discrepancies between experimental observations and theoretical predictions, we distinguish between the weight distribution {\cal P} (w) measured in experiments and analyzed in the q-model, and the distribution of interparticle forces P(f). The latter one is robust, while {\cal P}(w) can be obtained once the local packing geometry and P(f) are known. By manipulating the (boundary) geometry, we show that {\cal P}(w) can be varied drastically.

description: Recent experiments revealed that the dielectric dispersion spectrum of fission yeast cells in a suspension was mainly composed of two sub-dispersions. The low-frequency sub-dispersion depended on the cell length, while the high-frequency one was independent of it. The cell shape effect was simulated by an ellipsoidal cell model but the comparison between theory and experiment was far from being satisfactory. Prompted by the discrepancy, we proposed the use of spectral representation to analyze more realistic cell models. We adopted a shell-spheroidal model to analyze the effects of the cell membrane. It is found that the dielectric property of the cell membrane has only a minor effect on the dispersion magnitude ratio and the characteristic frequency ratio. We further included the effect of rotation of dipole induced by an external electric field, and solved the dipole-rotation spheroidal model in the spectral representation. Good agreement between theory and experiment has been obtained.

description: The N-qubit states of the W class, for N>10, lead to more robust (against noise admixture) violations of local realism, than the GHZ states. These violations are most pronounced for correlations for a pair of qubits, conditioned on specific measurement results for the remaining (N-2) qubits. The considerations provide us with a qualitative difference between the W state and GHZ state in the situation when they are separately sent via depolarizing channels. For sufficiently high amount of noise in the depolarizing channel, the GHZ states cannot produce a distillable state between two qubits, whereas the W states can still produce a distillable state in a similar situation.

description: The well-preserved archaeological landscape of the Doolin study area contains varied evidence of human activity from the prehistoric era through to modern times. These human – landscape interactions are evidenced by a range of monuments, field boundaries and finds across the study area. In the present study, closer analysis of some of these features, along with survey at various scales, have led to new discoveries and a greater understanding of how the land was used by past inhabitants. In addition, connections to other communities in the Burren and further afield have been explored, creating a more in- depth picture of this unique landscape through time. The Doolin study area and its surrounds have proved to be a key region in the study of the Early Neolithic in Ireland. Evidence for an overlap between indigenous Mesolithic hunter – gatherer groups and incoming Early Neolithic farmers, as well as evidence for the possible heterogeneity of incoming farming groups is present. Geophysical survey and morphological analysis of the Teergonean court tomb as part of the present study has added to this picture by demonstrating contrasts with other contemporary court tombs on the Burren and instead suggesting long-distance connections to the north of Ireland. Aerial and ground-surveying uncovered many previously unrecorded features, chronological relationships between features and field boundaries and two likely prehistoric settlement sites (probably Chalcolithic - Early Bronze Age). Amongst the new discoveries was a Chalcolithic wedge tomb, and this monument along with other wedge tombs in the study area, appear to be part of the wider distribution of similar wedge tombs on the Burren. The value of intensive ground-surveying has been demonstrated and a classification system for walls and features has been established for this region along with documented chronological relationships. Areas that warrant further ground-investigation have also been identified. The Early Medieval period is marked in the Doolin study area by intensive human activity resulting in an unusually high density of ringfort construction. Ringfort distribution studies here suggest the density may have been controlled by the quality of farmland as well as access to land and maritime travel routes. In general, the archaeology of the Doolin study area is comparable with that of other Burren and Irish locations. Closer examination, however, has demonstrated some differences and highlighted the importance of this geographically small area, particularly in light of earlier prehistoric human-landscape interactions.
Dust Spreading in Debris Discs: Do Small Grains Cling on to Their Birth Environment?

description: Debris discs are dusty belts of planetesimals around main-sequence stars, similar to the asteroid and Kuiper belts in our solar system. The planetesimals cannot be observed directly, yet they produce detectable dust in mutual collisions. Observing the dust, we can try to infer properties of invisible planetesimals. Here we address the question of what is the best way to measure the location of outer planetesimal belts that encompass extrasolar planetary systems. A standard method is using resolved images at mm-wavelengths, which reveal dust grains with sizes comparable to the observational wavelength. Smaller grains seen in the infrared (IR) are subject to several non-gravitational forces that drag them away from their birth rings, and so may not closely trace the parent bodies. In this study, we examine whether imaging of debris discs at shorter wavelengths might enable determining the spatial location of the exo-Kuiper belts with sufficient accuracy. We find that around M-type stars the dust best visible in the mid-IR is efficiently displaced inward from their birth location by stellar winds, causing the discs to look more compact in mid-IR images than they actually are. However, around earlier-type stars where the majority of debris discs is found, discs are still the brightest at the birth ring location in the mid-IR regime. Thus, sensitive IR facilities with good angular resolution, such as MIRI on JWST, will enable tracing exo-Kuiper belts in nearby debris disc systems.

The sequence of production of these fabrics at the factory "Yodgorlik" de�scribes the process from the separation of silk from cocoons to the formation of the finished fabric. The secrets of the old masters are still preserved here, and most of the work is done by hand. This is why the fabric comes out in a truly unique pattern, making it very difficult to replicate the same patterns.

description: We report on the experimental observation of strong-field dressing of an autoionizing two-electron state in helium with intense extreme-ultraviolet laser pulses from a free-electron laser. The asymmetric Fano line shape of this transition is spectrally resolved, and we observe modifications of the resonance asymmetry structure for increasing free-electron-laser pulse energy on the order of few tens of $μ$J. A quantum-mechanical calculation of the time-dependent dipole response of this autoionizing state, driven by classical extreme-ultraviolet (XUV) electric fields, reveals a direct link between strong-field-induced energy and phase shifts of the doubly excited state and the Fano line-shape asymmetry. The experimental results obtained at the Free-Electron Laser in Hamburg (FLASH) thus correspond to transient energy shifts on the order of few meV, induced by strong XUV fields. These results open up a new way of performing non-perturbative XUV nonlinear optics for the light-matter interaction of resonant electronic transitions in atoms at short wavelengths.

Our small angle neutron scattering investigation of the mixed phase reveals a crossover from triangular to square coordination with increasing magnetic field. The existence of an intrinsic square vortex lattice has never been observed in high-temperature superconductors (HTSC), and is indicative of the coupling of the vortex lattice to a source of anisotropy, such as those provided by a d-wave order parameter or the presence of stripes.

description: The transverse field profile of light is being recognized as a resource for classical and quantum communications for which reliable methods of sorting or demultiplexing spatial optical modes are required. Here, we demonstrate, experimentally, state-of-the-art mode demultiplexing of Laguerre-Gaussian beams according to both their orbital angular momentum and radial topological numbers using a flow of two concatenated deep neural networks. The first network serves as a transfer function from experimentally-generated to ideal numerically-generated data, while using a unique "Histogram Weighted Loss" function that solves the problem of images with limited significant information. The second network acts as a spatial-modes classifier. Our method uses only the intensity profile of modes or their superposition, making the phase information redundant.

Year: 2019
Subjects: subject: Nuclear Theory (nucl-th)

description: We present an effective field theory (EFT) at leading order to describe light single-$Λ$ hypernuclei. Owing to the weak $Λ$ binding and to the $ΛN$ short interaction range, meson exchange forces are approximated by contact interactions within a pionless EFT where the only degrees of freedom are baryons. At leading order, the $Λ$-nuclear interaction contains two 2-body (singlet and triplet) and three 3-body interaction terms, a total of 5 terms associated with 5 coupling strengths or low energy constants (LECs). We adopt the 2-body LECs from hyperon-nucleon scattering data and interaction models that constrain the $ΛN$ scattering lengths, while the 3-body LECs are adjusted using both 3-body and 4-body hypernuclear binding energies. To calculate the binding energies for A-body systems with A$>$2, we expand the wavefunctions using a correlated Gaussian basis. The stochastic variational method is employed to select the non-linear parameters. The resulting \nopieft~is then applied to calculate the $Λ$ separation energy in $_Λ^5$He, where the adjusted 3-body interactions largely resolve the known overbinding problem of $_Λ^5$He.

Piezoelectric mechanism of orientation of a bilayer Wigner crystal in a GaAs matrix

Year: 2001
Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: A mechanism for orientation of bilayer classical Wigner crystals in a piezoelectric medium is considered. For the GaAs system the piezoelectric correction to the electrostatic interaction between electrons is calculated. It is shown that taking into account the correction due to the piezoelectric effect leads to a dependence of the total energy of the electron crystal on its orientation with respect to the crystallographic axes of the surrounding matrix. A generalization of Ewald's method is obtained for calculating the anisotropic interaction between electrons in a Wigner crystal. The method is used to calculate the energy of bilayer Wigner crystals in electron layers parallel to the crystallographic planes (001), (0-11), and (111) as a function of their orientation and the distance between layers, and the energetically most favorable orientation for all types of electron lattices in a bilayer system is found. It is shown that phase transitions between structures with different lattice symmetry in a Wigner crystal can be accompanied by a change of its orientation.

description: Nonsequential two-photon ionization of inner-shell $np$ subshell of neutral atoms by circularly polarized light is investigated. Detection of subsequent fluorescence as a signature of the process is proposed and the dependence of fluorescence degree of polarization on incident photon beam energy is studied. It is generally expected that the degree of polarization remains approximately constant, except when the beam energy is tuned to an intermediate $n's$ resonance. However, strong unexpected change in the polarization degree is discovered for nonsequential two-photon ionization at specific incident beam energy due to a zero contribution of the otherwise dominant ionization channel. Polarization degree of the fluorescence depends less on the beam parameters and its measurements at this specific beam energy, whose position is very sensitive to the details of the employed theory, are highly desirable for evaluation of theoretical calculations of nonlinear ionization at hitherto unreachable accuracy.

Harsh growing conditions, dry cli�mate, vertical zones, localization of forests on the slopes of northern exposures, whereas the opposite forestless slopes have created more or less tolerable conditions for the existence of only one species. It is Tien-Shan’s spruce. According to some sources forests of Northern Kyrgyzstan was not consist of only one species. In past his�torical periods in their composition was also attended by Pseudotsuga of Asian species, hemlock and other wood species. The unsatisfactory natural resumption of local breed, intensified exploitation of spruce forests of Kyrgyzstan during the last hundred years, cattle grazing, and in recent years the recreation led to serious concerns for their further fate. One of the ways to solve this situation may be introduction of tree species in the region. In last 80 years’ different tree species was been tested for the enrichment of species composition, productivity improvement of spruce forests and for landscaping purposes. One of these species, which may in a relatively short time increase forest productivity is Pseudotsuga. The prospects of its breeding noted in many countries of Europe. In Central Asia, small areas of artificial plantations of this species are only in Kyrgyzstan. Currently, the second stage of introduction of this breed in Kyrgyzstan is underway. Pseudotsuga in local conditions creates highly productive plantations, developing according to class I bonitas, tolerates harsh forest conditions,also there is a natural resumption. Not affected by pests and diseases. Among the shortcomings, a rela�tively high trunkshift should be noted. In general, this breed can be recommended for plantation afforestation and widespread introduction into the belt of spruce forests of Northern Kyrgyzstan.

description: A theoretical study of the specific heat C(T) as a function of temperature in Fibonacci magnetic superlattices is presented. We consider quasiperiodic structures composed of ferromagnetic films, each described by the Heisenberg model, with biquadratic and bilinear coupling between them. We have taken the ratios between the biquadratic and bilinear exchange terms according to experimental data recently measured for different regions of their regime. Although some previous properties of the spin wave specific heat are also reproduced here, new features appear in this case, the most important of them being an interesting broken-symmetry related to the interlayer biquadratic term.

description: Experimental signatures of charge density waves (CDW) in high-temperature superconductors have evoked much recent interest, yet an alternative interpretation has been theoretically raised based on electronic standing waves resulting from quasiparticles scattering off impurities or defects, also known as Friedel oscillations (FO). Indeed the two phenomena are similar and related, posing a challenge to their experimental differentiation. Here we report a resonant X-ray diffraction study of ZrTe$_3$, a model CDW material. Near the CDW transition, we observe two independent diffraction signatures that arise concomitantly, only to become clearly separated in momentum while developing very different correlation lengths in the well-ordered state. Anomalously slow dynamics of mesoscopic ordered nanoregions are further found near the transition temperature, in spite of the expected strong thermal fluctuations. These observations reveal that a spatially-modulated CDW phase emerges out of a uniform electronic fluid via a process that is promoted by self-amplifying FO, and identify a viable experimental route to distinguish CDW and FO.

description: In our days, photochromic polymers possessing the liquid crystalline behaviour attract considerable attention of the scientific community due to their functionality and highlighted effects which can be used for opto-electronics and photonics. Herein, the photoorientation processes under the action of the polarised UV (355 nm) and visible (457 nm) light are studied for the amorphousized films of new azobenzene-containing polymethacrylates with different lengths of alkyl spacers and tails (5, 6 and 10 methylene units). The prominent effects of the chemical structure, namely length of the alkyl spacers and tails, as well as wavelength of the excitation light, on the peculiarities of the photoorientation process are demonstrated. Those effects can lead to quite important conclusions concerning possible influence of the microphase separation in polymer films.

description: The combined methods of surface treatment for obtaining heat-resistant coatings, proposed by us, consist in a combination of various kinds of influences on the material being processed. For example, the nitriding process is combined with the preliminary activation of the surface by means of an electric discharge in an inert gas medium. This makes it possible to intensify the process of diffusion saturation, to increase the depth of the modified layer and its microhardness. Similar goals are also achieved with a combination of gas nitriding and pretreatment of the product surface with laser radiation. We associate the radiation resistance of the Zn-Al coating with its pronounced globular structure. The presence of such a system of "balls" leads to elastic scattering of argon ions, so that the local deformation turns out to be insignificant.

Hexatic-Herringbone Coupling at the Hexatic Transition in Smectic Liquid Crystals: 4-$ε$ Renormalization Group Calculations Revisited

description: Simple symmetry considerations would suggest that the transition from the smectic-A phase to the long-range bond orientationally ordered hexatic smectic-B phase should belong to the XY universality class. However, a number of experimental studies have constantly reported over the past twenty years "novel" critical behavior with non-XY critical exponents for this transition. Bruinsma and Aeppli argued in Physical Review Letters {\bf 48}, 1625 (1982), using a $4-ε$ renormalization-group calculation, that short-range molecular herringbone correlations coupled to the hexatic ordering drive this transition first order via thermal fluctuations, and that the critical behavior observed in real systems is controlled by a `nearby' tricritical point. We have revisited the model of Bruinsma and Aeppli and present here the results of our study. We have found two nontrivial strongly-coupled herringbone-hexatic fixed points apparently missed by those authors. Yet, those two new nontrivial fixed-points are unstable, and we obtain the same final conclusion as the one reached by Bruinsma and Aeppli, namely that of a fluctuation-driven first order transition. We also discuss the effect of local two-fold distortion of the bond order as a possible missing order parameter in the Hamiltonian.

Holographic Renormalization Group Structure in Higher-Derivative Gravity

description: Classical higher-derivative gravity is investigated in the context of the holographic renormalization group (RG). We parametrize the Euclidean time such that one step of time evolution in (d+1)-dimensional bulk gravity can be directly interpreted as that of block spin transformation of the d-dimensional boundary field theory. This parametrization simplifies the analysis of the holographic RG structure in gravity systems, and conformal fixed points are always described by AdS geometry. We find that higher-derivative gravity generically induces extra degrees of freedom which acquire huge mass around stable fixed points and thus are coupled to highly irrelevant operators at the boundary. In the particular case of pure R^2-gravity, we show that some region of the coefficients of curvature-squared terms allows us to have two fixed points (one is multicritical) which are connected by a kink solution. We further extend our analysis to Minkowski time to investigate a model of expanding universe described by the action with curvature-squared terms and positive cosmological constant, and show that, in any dimensionality but four, one can have a classical solution which describes time evolution from a de Sitter geometry to another de Sitter geometry, along which the Hubble parameter changes drastically.

On the discreet spectrum of fractional quantum hydrogen atom in two dimensions

description: We consider a fractional generalization of two-dimensional (2D) quantum-mechanical Kepler problem corresponding to 2D hydrogen atom. Our main finding is that the solution for discreet spectrum exists only for $μ>1$ (more specifically $1 < μ\leq 2$, where $μ=2$ corresponds to "ordinary" 2D hydrogenic problem), where $μ$ is the Lévy index. We show also that in fractional 2D hydrogen atom, the orbital momentum degeneracy is lifted so that its energy starts to depend not only on principal quantum number $n$ but also on orbital $m$. To solve the spectral problem, we pass to the momentum representation, where we apply the variational method. This permits to obtain approximate analytical expressions for eigenvalues and eigenfunctions with very good accuracy. Latter fact has been checked by numerical solution of the problem. We also found the new integral representation (in terms of complete elliptic integrals) of Schrödinger equation for fractional hydrogen atom in momentum space. We point to the realistic physical systems like bulk semiconductors as well as their heterostructures, where obtained results can be used.

description: We present quasi-elastic light scattering (LS) and dielectric (DS) spectra of the glass former alpha-picoline (13K < T < 320K). At high temperatures the evolution of the susceptibility minimum is well described by mode coupling theory (MCT) yielding a critical temperature T_c = 162K +- 5K. At T_c > T > T_g the excess wing of the alpha-process identified in the DS spectra and characterized by a power-law exponent c is rediscovered in the LS spectra. Introducing a universal evolution for c = c[lg(tau_{alpha})] as suggested by DS data of several glass formers, the fast dynamics spectrum is singled out, allowing to determine the non-ergodicity parameter f(T). The latter shows the predicted cusp-like anomaly identifying T_c as well. Another discontinuous change of f(T) is observed at T_g. The fast dynamics spectra exhibit a crossover to ``white noise'' (T < T_c). Concerning the fast dynamics, we conclude that idealized MCT predictions hold even below T_c.

description: Semantic Segmentation is an important module for autonomous robots such as self-driving cars. The advantage of video segmentation approaches compared to single image segmentation is that temporal image information is considered, and their performance increases due to this. Hence, single image segmentation approaches are extended by recurrent units such as convolutional LSTM (convLSTM) cells, which are placed at suitable positions in the basic network architecture. However, a major critique of video segmentation approaches based on recurrent neural networks is their large parameter count and their computational complexity, and so, their inference time of one video frame takes up to 66 percent longer than their basic version. Inspired by the success of the spatial and depthwise separable convolutional neural networks, we generalize these techniques for convLSTMs in this work, so that the number of parameters and the required FLOPs are reduced significantly. Experiments on different datasets show that the segmentation approaches using the proposed, modified convLSTM cells achieve similar or slightly worse accuracy, but are up to 15 percent faster on a GPU than the ones using the standard convLSTM cells. Furthermore, a new evaluation metric is introduced, which measures the amount of flickering pixels in the segmented video sequence.
