description: Redshifts of an astronomical body measured at multiple epochs (e.g., separated by 10 years) are different due to the cosmic expansion. This so-called Sandage-Loeb test offers a direct measurement of the expansion rate of the Universe. However, acceleration in the motion of Solar System with respect to the cosmic microwave background also changes redshifts measured at multiple epochs. If not accounted for, it yields a biased cosmological inference. To address this, we calculate the acceleration of Solar System with respect to the Local Group of galaxies to quantify the change in the measured redshift due to local motion. Our study is motivated by the recent determination of the mass of Large Magellanic Cloud (LMC), which indicates a significant fraction of the Milky Way mass. We find that the acceleration towards the Galactic Center dominates, which gives a redshift change of 7 cm/s in 10 years, while the accelerations due to LMC and M31 cannot be ignored depending on lines of sight. We create all-sky maps of the expected change in redshift and the corresponding uncertainty, which can be used to correct for this effect.

description: Parking occupancy in the area is defined by three major parameters - the rate of cars arrivals, the dwell time of already parked cars, and the willingness of drivers who are searching but yet did not find a vacant parking spot, to continue their search. We investigate a series of theoretical and numeric models, deterministic and stochastic, that describe parking dynamics in the area as dependent on these parameters, over the entire spectrum of the demand to supply ratio, focusing on the case when the demand is close to or above the supply. We demonstrate that a simple deterministic model provides a good analytical approximation for the major characteristics of the parking system - the average fraction of cars among the arriving that will find parking in the area, the average number of cars that cruise for parking, and average cruising time. Stochastic models make it possible to estimate the distributions of these characteristics as well as the parameters that are related to the variance of these distributions, like the fraction of the arriving cars that find parking in less than t minutes.

description: The purpose of this review is to survey the literature addressing the employment effects of brownfield redevelopment. Economic development has emerged as a potential goal of the environmental cleanup process. The evolving literature (1) addresses the redevelopment and job creation that has followed the numerous cases of environmental remediation; (2) continues to debate whether brownfield redevelopment creates new jobs or leads to the spatial reallocation of existing jobs; and (3) documents emerging efforts to tie brownfield redevelopment benefits to local residents and the un- or underemployed. The existing literature highlights the difficulties of moving from site cleanup to neighborhood revitalization. The literature is clear: site cleanup alone is typically not enough to stimulate neighborhood regeneration in the most distressed neighborhoods. There are tradeoffs between financial feasibility and tackling the most contaminated sites in the most distressed neighborhoods, and the redevelopment in these neighborhoods generally required large government subsidies. The literature highlights many positive developments and experiments. Apparent successes involve large scale plans that integrate site cleanup with wider community plans, the growing tendency to link jobs on brownfield sites to local residents, increasingly sophisticated subsidies and incentives, and the importance of design that integrates redevelopment with the existing neighborhood. To steer clear of gentrification, redevelopment strategies should focus on attracting employers who will hire local workers.

description: This paper reviews the distributional impacts associated with "environmental gentrification" following the cleanup and reuse of Superfund sites, brownfields, and other locally undesirable land uses (LULUs). By making a neighborhood more attractive, cleanup and reuse of LULUs may drive up local real estate prices. Renters in the neighborhood would have to pay higher rents. Although they would also reap a capital gain, homeowners too would face higher housing costs, including perhaps higher tax bills. Moreover, existing residents may not value the removal of the disamenity as much as other households, creating a mismatch between their priorities and the new character of the neighborhood. Thus, even if they do not move, existing residents, especially renters, may be harmed by the gentrification effects of cleanup. If many former residents do move, to be replaced by wealthier households, the character of the neighborhood would change further, feeding the gentrification. Such environmental gentrification is a key concern of local stakeholders. Nevertheless, the extent of environmental gentrification, if any, following cleanup and reuse of LULUs has not been solidly confirmed in the empirical literature. This paper seeks to fill that void by reviewing the evidence to date. We find limited evidence for rising real estate prices following cleanup of LULUs. We find stronger evidence for increased housing density and increasing incomes, but no evidence for racial impacts. Our review also uncovers a variety of factors that are likely to temper the adverse consequences of gentrification for residents.

description: When inhaled nanoparticles (NPs) deposit in alveoli, they transit through the pulmonary surfactant (PS), a biofluid made of proteins and phospholipidic vesicles. They acquire a corona reflecting the PS-nanomaterials interaction. Since the corona determines directly the NPs biological fate, the question of its nature and structure is central. Here, we report on the corona architecture raising after incubation of positive or negative silica particles with Curosurf, a biomimetic pulmonary surfactant of porcine origin. Using optical, electron and cryo-electron microscopy (cryo-TEM), we determine the pulmonary surfactant corona structure at different scales of observation. Contrary to common belief, the PS corona is not only constituted by phospholipidic bilayers surrounding NPs but by multiple hybrid structures derived from NPs-vesicles interaction. Statistical analysis of cryo-TEM images provides interesting highlights about the nature of the corona depending on the particle charge. The influence of Curosurf pre- or post-treatment is also investigated and demonstrate the need of protocols standardization.

Constraints on the merging binary neutron star mass distribution and equation of state based on the incidence of jets in the population

description: A relativistic jet has been produced in the single well-localised binary neutron star (BNS) merger detected to date in gravitational waves (GWs), and the local rates of BNS mergers and short gamma-ray bursts are of the same order of magnitude. This suggests that jet formation is not a rare outcome for BNS mergers, and we show that this intuition can be turned into a quantitative constraint: at least about $1/3$ of GW-detected BNS mergers, and at least about $1/5$ of all BNS mergers, should produce a successful jet (90\% credible level). Whether a jet is launched depends on the properties of the merger remnant and of the surrounding accretion disc, which in turn are a function of the progenitor binary masses and equation of state (EoS). The incidence of jets in the population therefore carries information about the binary component mass distribution and EoS. Under the assumption that a jet can only be produced by a black hole remnant surrounded by a non-negligible accretion disc, we show how the jet incidence can be used to place a joint constraint on the space of BNS component mass distributions and EoS. The result points to a broad mass distribution, with particularly strong support for masses in the $1.3-1.6\,\mathrm{M_\odot}$ range. The constraints on the EoS are shallow, but we show how they will tighten as the knowledge on the jet incidence improves. We also discuss how to extend the method to include future BNS mergers, with possibly uncertain jet associations.

description: A single physical interaction might not be universal for quantum computation in general. It has been shown, however, that in some cases it can generate universal quantum computation over a subspace. For example, by encoding logical qubits into arrays of multiple physical qubits, a single isotropic or anisotropic exchange interaction can generate a universal logical gate-set. Recently, encoded universality for the exchange interaction was explicitly demonstrated on three-qubit arrays, the smallest nontrivial encoding. We now present the exact specification of a discrete universal logical gate-set on four-qubit arrays. We show how to implement the single qubit operations exactly with at most 3 nearest neighbor exchange operations and how to generate the encoded controlled-not with 29 parallel nearest neighbor exchange interactions or 54 serial gates, obtained from extensive numerical optimization using genetic algorithms and Nelder-Mead searches. Our gate-sequences are immediately applicable to implementations of quantum circuits with the exchange interaction.

description: Neutron stars with extremely high central energy density are natural laboratories to investigate the appearance and the properties of compactified extra dimensions with small compactification radius, if they exist. Using the same formalism, these exotic hybrid stars can be described as neutron stars with quark core, where the high energy density allows the presence of heavy quarks (c, b, t). We compare the two scenarios for hybrid stars and display their characteristic features.

Lett. {\bf 90}, 177002 (2003)) theoretical results for the mixed state of a dirty two-band superconductor. Introducing a simple model for the excess current in the point contact in the mixed state our data can be qualitatively described utilizing theoretical magnetic filed behavior of the $σ$ and $π$-band superconducting order parameters and the corresponding averaged electronic density of states in MgB$_2$.

The purpose of article is to characterize theoretical aspects of development of integration processes in agricultural sector and the integrated agrarian formations; to reveal individual factors of influence on integration processes and to review the multivector diffusion which is formed in process of creation of vertically integrated structure; to explore the main advantages and disadvantages of the integrated structure of holding type. Methodology / method / approach. The research of theoretical principles of integration processes development and their organizational forms gave the chance to substantiate scientific and practical positions concerning content and role of this phenomenon for subjects of the agrarian sector of economy. In process of writing article such methods are used: logical generalization – for theoretical justification of integration essence, integrated agrarian formations and agroholdings; the system analysis – for research and justification of multivector diffusion emergence in process of integration into structure of holding type. Results. The essence and approaches to understanding of integration as social and economic phenomenon in the agrarian sector of economy are determined. It is reasoned that vertical integration into agro-industrial structures of holding type are the most successful organizational forms for today. But at the same time it is reasoned that there is quite large number of unresolved issues concerning activity of such holding structures, the main of them are institutional unresolvations concerning property and institutional traps. It is proved that in process of integration of agricultural enterprises as participants of agroholdings, there is multivector diffusion by means of which there are internal organizational and administrative and production transformations of the participant of integration. Originality / scientific novelty. The attempt to investigate influence of the most widespread integrated formation – agrarian holding on its participants (the agricultural enterprises of different forms of ownership) and also to determine negative aspects of vertical integration and possible ways of their overcoming are made. Practical value / significance. The motivational component of the integration of agricultural enterprises into agro-industrial holding structures (agroholdings) is determined. The scheme of multivector diffusion in process of integration into structure of holding type is developed and the influence on its participants is determined. The list of negative aspects of vertical integration into agroindustrial complex is offered and the ways of their overcoming are determined.

description: Complex scalar fields charged under approximate $U(1)$ symmetries appear in well-motivated extensions of the Standard Model. One example is the field that contains the QCD axion field associated with the Peccei-Quinn symmetry; others include flat directions in supersymmetric theories with baryon, lepton, or flavor charges. These fields may take on large values and rotate in field space in the early universe. The relevant approximate $U(1)$ symmetry ensures that the angular direction of the complex field is light during inflation and that the rotation is thermodynamically stable and is long-lived. These properties allow rotating complex scalar fields to naturally serve as curvatons and explain the observed perturbations of the universe. The scenario imprints non-Gaussianity in the curvature perturbations, likely at a level detectable in future large scale structure observations. The rotation can also explain the baryon asymmetry of the universe without producing excessive isocurvature perturbations.

description: We show that the ground state of the well-known pseudo-stationary states for the Caldirola-Kanai Hamiltonian is a generalized minimum uncertainty state, which has the minimum allowed uncertainty $Δq Δp = \hbar σ_0/2$, where $σ_0 (\geq 1)$ is a constant depending on the damping factor and natural frequency. The most general symmetric Gaussian states are obtained as the one-parameter squeezed states of the pseudo-stationary ground state. It is further shown that the coherent states of the pseudo-stationary ground state constitute another class of the generalized minimum uncertainty states.

Color Image Inpainting via Robust Pure Quaternion Matrix Completion: Error Bound and Weighted Loss

description: In this paper, we study color image inpainting as a pure quaternion matrix completion problem. In the literature, the theoretical guarantee for quaternion matrix completion is not well-established. Our main aim is to propose a new minimization problem with an objective combining nuclear norm and a quadratic loss weighted among three channels. To fill the theoretical vacancy, we obtain the error bound in both clean and corrupted regimes, which relies on some new results of quaternion matrices. A general Gaussian noise is considered in robust completion where all observations are corrupted. Motivated by the error bound, we propose to handle unbalanced or correlated noise via a cross-channel weight in the quadratic loss, with the main purpose of rebalancing noise level, or removing noise correlation. Extensive experimental results on synthetic and color image data are presented to confirm and demonstrate our theoretical findings.

description: In this paper, we study the motion of test particle and light around the Global Monopole in asymptotically dS/AdS spacetime. The motion of a test particle and light in the exterior region of the global monopole in dS/AdS spacetime has been investigated. Although the test particle's motion is quite different from the case in asymptotically flat spacetime, the behaviors of light(null geodesic) remain unchanged except a energy(frequency) shift. Through a phase-plane analysis, we prove analytically that the existence of a periodic solution to the equation of motion for a test particle will not be altered by the presence of cosmological constant and the deficit angle, whose presence only affects the position and type of the critical point on the phase plane. We also show that the apparent capture section of the global monopole in dS/AdS spacetime is quite different from that in flat spacetime.

description: In recent years, large datasets of high-resolution mammalian neural images have become available, which has prompted active research on the analysis of gene expression data. Traditional image processing methods are typically applied for learning functional representations of genes, based on their expressions in these brain images. In this paper, we describe a novel end-to-end deep learning-based method for generating compact representations of in situ hybridization (ISH) images, which are invariant-to-translation. In contrast to traditional image processing methods, our method relies, instead, on deep convolutional denoising autoencoders (CDAE) for processing raw pixel inputs, and generating the desired compact image representations. We provide an in-depth description of our deep learning-based approach, and present extensive experimental results, demonstrating that representations extracted by CDAE can help learn features of functional gene ontology categories for their classification in a highly accurate manner. Our methods improve the previous state-of-the-art classification rate (Liscovitch, et al.) from an average AUC of 0.92 to 0.997, i.e., it achieves 96% reduction in error rate. Furthermore, the representation vectors generated due to our method are more compact in comparison to previous state-of-the-art methods, allowing for a more efficient high-level representation of images. These results are obtained with significantly downsampled images in comparison to the original high-resolution ones, further underscoring the robustness of our proposed method.

description: The past year has witnessed a large increase in our knowledge of the polarization properties of Gamma-Ray Burst (GRB) radiation. In the prompt phase, the measurement (albeit highly debated) of a large degree of linear polarization in GRB 021206 has stimulated a deep theoretical study of polarization from GRB jets. The optical afterglow of GRB 030329, on the other hand, has been followed thoroughly in polarimetric mode, allowing for an unprecedented sampling of its polarization curve. I will review the present status of theories and observations of polarization in GRBs, focusing on how polarimetric observations and their modelling can give us informations on the structure and magnetisation o GRB jets which is not possible to obtain from their light curve.

description: We inaugurate a program of ``mass production'' of microlensing planets discovered in 2021 KMTNet data, with the aim of laying the basis for future statistical studies. While we ultimately plan to quickly publish all 2021 planets meeting some minimal criteria, the current sample of four was chosen simply on the basis of having low initial estimates of the planet-host mass ratio, $q$. It is therefore notable that 2 members of this sample suffer from a degeneracy in the normalized source radius $ρ$ that arises from different morphologies of closely spaced caustics. All four planets [KMT-2021-BLG-(1391,1253,1372,0748)] have well-characterized mass ratios, $q$, and therefore are suitable for mass-ratio frequency studies. Both of the $ρ$ degeneracies can be resolved by future adaptive optics (AO) observations on 30m class telescopes. We provide general guidance for such AO observations for all events in anticipation of the prospect that they will revolutionize the field of microlensing planets.

description: We demonstrate a direct correspondence between the basis states of the minimal ideals of the complex Clifford algebras $\mathbb{C}\ell(6)$ and $\mathbb{C}\ell(4)$, shown earlier to transform as a single generation of leptons and quarks under the Standard Model's unbroken $SU(3)_c\times U(1)_{em}$ and $SU(2)_L$ gauge symmetries respectively, and a simple topologically-based toy model in which leptons, quarks, and gauge bosons are represented as elements of the braid group $B_3$. It was previously shown that mapping the basis states of the minimal left ideals of $\mathbb{C}\ell(6)$ to specific braids replicates precisely the simple topological structure describing electrocolor symmetries in an existing topological preon model. This paper extends these results to incorporate the chiral weak symmetry by including a $\mathbb{C}\ell(4)$ algebra, and identifying the basis states of the minimal right ideals with simple braids. The braids corresponding to the charged vector bosons are determined, and it is demonstrated that weak interactions can be described via the composition of braids.

description: Sputter thin film deposition after photolithography often produces unwanted spikes along the side edges. These spikes are a significant issue for the development of magnetic tunnel junction (MTJ)-based memory and molecular spintronics devices, microelectronics, and micro-electro-mechanical systems because they influence the properties of the other films deposited on the top. Our molecular spintronics devices that utilize MTJ as the testbed are almost short-lived and encountered high background current that masked the effect of molecular transport channels placed along the sides of MTJs. Therefore, tapered thin film edges are critically needed in devices. Here, we report a very cost-efficient and fast way of creating an optimum photoresist profile for the production of spike-free patterned films. This approach is based on performing a soaking in the photoresist developer after baking and before the UV exposure. However, the success of this method depends on multiple factors accounted for during photolithography - photoresist thickness (spin speed), baking temperature, soaking time and exposure time. Our recent experiments systematically studied the effect of these factors by following the L9 experimental scheme of the Taguchi Design of the experiment (TDOE). We discovered that baking temperature was the most influential parameter; presoak time and photoresist thickness were two other influential factors; exposure time was the least effective factor. We also found that 4000 rpm, 100 C soft baking, 60 s soaking, and 15 s UV exposure yielded the best results. Finally, the paper also discusses the interdependence of selected factors, and the impact of the individual levels of each factor. This study is expected to benefit MEMS and micro/nanoelectronics device researchers because it attempts at finding a cheaper and faster alternative to creating an optimum photoresist profile.

description: We present a neutron scattering analysis of the density and the static structure factor of confined methanol at various temperatures. Confinement is performed in the cylindrical pores of MCM-41 silicates with pore diameters D=24 angstrom and D=35 angstrom. A change of the thermal expansivity of confined methanol at low temperature is the signature of a glass transition, which occurs at higher temperature for the smallest pore. This is an evidence of a surface induced slowing down of the dynamics of the fluid. The structure factor presents a systematic evolution with the pore diameter, which has been analyzed in terms of excluded volume effects and fluid-matrix cross-correlation. Conversely to the case of Van der Waals fluids, it shows that stronger fluid-matrix correlations must be invoked most probably in relation with the H-bonding character of both methanol and silicate surface.

description: Purpose. Rural households spend a large share of their daily time to search for grazing feed, water resource and collect straw by displacing labor time away from crop farming activities. This paper aims to analyze the economic effect of time spent looking for animal water and grazing areas on farm labor input and crop farm output. Methodology / approach. To address our objectives, a general Cobb-Douglas production function was estimated using a unique dataset from 518 sample farmers in Tigrai, Ethiopia drawing on a non-separable farm household model. Results. The results favor the hypothesis of a negative relationship between crop output and resource scarcity. In aggregate, the findings confirm that reducing time spent looking for water, grazing and straw by 1 % leads to an increase in food production by 0.155 %, 0.279 % and 0.328 % respectively. Similarly, the shadow price variables are significant, have the expected negative sign and are consistent with the theory. The sign of other factors are consistent with the prediction of the economic theory. Originality / scientific novelty. The noble contribution of this paper is, unlike previous studies, we collected information on the entire set of crop production, along with the distance to grazing, water and crop residue of each household. This paper considers three important resources for an animal such as grazing, water and crop residue, of which the first two have not been explored well. The use of distance level and shadow price as resource scarcity indicators is an extra benefit to the literature. Practical value / implications. The results of this paper provide an interesting picture of stallholders in Ethiopia. As expected, it appears that time spent searching for animal water and feed has a significant and negative effect on labor and crop output. Our results got the evidence of a negative relationship between labor input to crop farming and resource scarcity.

description: Amyloid fibers are aggregates of proteins. They are built out of a peptide called $β$--amyloid (A$β$) containing between 41 and 43 residues, produced by the action of an enzyme which cleaves a much larger protein known as the Amyloid Precursor Protein (APP). X-ray diffraction experiments have shown that these fibrils are rich in $β$--structures, whereas the shape of the peptide displays an $α$--helix structure within the APP in its biologically active conformation. A realistic model of fibril formation is developed based on the seventeen residues A$β$12--28 amyloid peptide, which has been shown to form fibrils structurally similar to those of the whole A$β$ peptide. With the help of physical arguments and in keeping with experimental findings, the A$β$12--28 monomer is assumed to be in four possible states (i.e., native helix conformation, $β$--hairpin, globular low--energy state and unfolded state). Making use of these monomeric states, oligomers (dimers, tertramers and octamers) were constructed. With the help of short, detailed Molecular Dynamics (MD) calculations of the three monomers and of a variety of oligomers, energies for these structures were obtained. Making use of these results within the framework of a simple yet realistic model to describe the entropic terms associated with the variety of amyloid conformations, a phase diagram can be calculated of the whole many--body system, leading to a thermodynamical picture in overall agreement with the experimental findings. In particular, the existence of micellar metastable states seem to be a key issue to determine the thermodynamical properties of the system.
