description: This work is concerned with the large time behavior of solutions to the barotropic compressible Navier-Stokes equations in $\mathbb{R}^{d}(d\geq2)$. Precisely, it is shown that if the initial density and velocity additionally belong to some Besov space $\dot{B}^{-σ_1}_{2,\infty}$ with $σ_1\in (1-d/2, 2d/p-d/2]$, then the $L^p$ norm (the slightly stronger $\dot{B}^{0}_{p,1}$ norm in fact) of global solutions admits the optimal decay $t^{-\frac{d}{2}(\frac 12-\frac 1p)-\frac{σ_1}{2}}$ for $t\rightarrow+\infty$. In contrast to refined time-weighted approaches ([11,43]), a pure energy argument (independent of the spectral analysis) has been developed in more general $L^p$ critical framework, which allows to remove the smallness of low frequencies of initial data. Indeed, bounding the evolution of $\dot{B}^{-σ_1}_{2,\infty}$-norm restricted in low frequencies is the key ingredient, whose proof mainly depends on non standard $L^p$ product estimates with respect to different Sobolev embeddings. The result can hold true in case of large highly oscillating initial velocities.

The rest-frame UV luminosity function of protocluster galaxies at z~4 revealed by HSC-SSP
Creators: name: Ito, Kei
Publisher: name: Zenodo
Year: 2021

description: Various studies report the higher star formation rate of protocluster galaxies at z~2. It is crucial to investigate the picture at higher redshift. On the other hand, it was not impractical due to the lack of enough samples of the protoclusters. We estimate the rest-frame ultraviolet luminosity function of g-dropout galaxies in 177 protocluster candidates (PC UVLF) at z∼4 selected in the PDR1 of the Hyper Suprime-Cam Subaru Strategic Program. Comparing it with the UVLF of field galaxies at the same redshift, we find that the PC UVLF shows a significant excess toward the bright end. This study shows that the enhancement in star formation in overdense regions can generally be seen as early as at z∼4. We also estimate the star formation rate density in protocluster regions as 6-20% of the cosmic SFRD, based on the measured PC UVLF after correction for the selection incompleteness in our protocluster sample. This high value suggests that protoclusters make a non-negligible contribution to the cosmic SFRD at z∼4, as previously suggested by simulations. We will also show the result of the latest HSC-SSP data release.

description: The x-ray emission of hot spots on the surface of neutron stars is the prime target of the Neutron star Interior Composition Explorer (NICER). These x-ray pulse profiles not only encode information of the bulk properties of these stars, which teaches us about matter at supranuclear densities, but also about the spacetime curvature around them which teaches us about relativistic gravity. We explore the possibility of performing strong-gravity tests with NICER observations using a recently developed pulse profile model beyond general relativity. Our results suggest that NICER can place constraints on deviations from general relativity due to an additional scalar degree of freedom which are independent and competitive relative to constraints with binary pulsar observations.

The results are important in providing a test for approximate theories of the antiferromagnetic ground state.

Resolving Galaxies in Cosmic Infrared Background Peaks of the Planck Survey
Creators: name: Kneissl, Rüdiger
Publisher: name: Zenodo
Year: 2021

description: The Planck all-sky survey at mm/submm wavelengths has provided a census of the brightest peaks in the cosmic infrared background on angular scales of several arcminutes. Herschel follow-up of the Planck sample has shown that only a few of these sources are individually bright, lensing magnified galaxies, and that the majority are high overdensities of dusty star-forming galaxies (SFGs) at redshifts z ≃ 2-4. In a detailed study of the proto-cluster candidate PLCK G073.4-57.5 with ALMA (Kneissl+2019) 18 millimetre galaxies brighter than 0.3 mJy are detected. Combining with NIR+FIR data, photometric redshifts, infrared luminosities, star-formation rates (SFRs), stellar masses (ℳ), dust temperatures, and dust masses are derived for two photometric redshift groups at z ≃ 1.5 and 2.4 with star-formation rates of 103 M⊙/yr each. Most galaxies show main sequence (MS) star-formation rates. The overall analysis of stellar masses, SFRs, and gas fractions of the ALMA sources in the two structures at z ≃ 1.5 / 2.4 suggest that the former contains more evolved galaxies with stellar masses larger than the expected ℳ∗ , and SFRs consistent with the MS, while the latter contains a mix of sources, consistent with a scenario, where some galaxies at the higher redshift are still actively growing.

description: The galaxy cluster Abell 746 (A746; $z$=0.214), featuring a double radio relic system, two isolated radio relics, a possible radio halo, disturbed V-shaped X-ray emission, and intricate galaxy distributions, is a unique and complex merging system. We present a weak-lensing analysis of A746 based on wide-field imaging data from Subaru/Hyper Suprime-Cam observations. The mass distribution is characterized by a main peak which coincides with the center of the X-ray emission. At this main peak, we detect two extensions toward the north and west, tracing the cluster galaxy and X-ray distributions. Despite the ongoing merger, our estimate of the A746 global mass $M_{500}=4.4\pm1.0\times10^{14}~M_{\odot}$ is consistent with the previous results from SZ and X-ray observations. We conclude that reconciling the distributions of mass, galaxies, and intracluster medium with the double radio relic system and other radio features remains challenging.

description: Inverted indexes are vital in providing fast key-word-based search. For every term in the document collection, a list of identifiers of documents in which the term appears is stored, along with auxiliary information such as term frequency, and position offsets. While very effective, inverted indexes have large memory requirements for web-sized collections. Recently, the concept of learned index structures was introduced, where machine learned models replace common index structures such as B-tree-indexes, hash-indexes, and bloom-filters. These learned index structures require less memory, and can be computationally much faster than their traditional counterparts. In this paper, we consider whether such models may be applied to conjunctive Boolean querying. First, we investigate how a learned model can replace document postings of an inverted index, and then evaluate the compromises such an approach might have. Second, we evaluate the potential gains that can be achieved in terms of memory requirements. Our work shows that learned models have great potential in inverted indexing, and this direction seems to be a promising area for future research.

description: The quantum critical behavior of an interacting, non-relativistic Bose theory with quenched disorder randomly distributed in space is investigated. The renormalization group is carried out in a double $ε$ expansion, where one $ε$ is the deviation of the effective space-time dimensionality from 4, while the other denotes the number of time dimensions. The disordered theory, which displays localization in the superfluid state, is shown to possess an infrared stable fixed point.

description: This research proposes implications of application functions by using the chain traceability data acquired from the Smart Object attached with Extended Real-time Data (SO-ERD: e.g. smart container, smart pallet, etc.) to improve risk management at the level of the logistics chain. Recent applications using traceability data and major issues in traceability systems have been explored by an academic literature. Information is classified by the usage of current traceability data for supporting risk detection and decisions in operational, tactical, and strategical levels. It is found that real-time data has been a significant impact on the usage for the transportation activity in all decision levels such the function of food quality control and collaborative planning among partners. However, there are some uncertainties in the aggregation of event-based traceability data captured by various partners which are preventing the adoption of data usage for the chain. Under the environment of Industry 4.0 and the Internet of Things (IoT), the SO-ERD enables independent data tracing through the chain in real-time. Its data has potential to overcome current issues and improve the supply chain risk management. Therefore, Implications of risk management are proposed with the usage of SO-ERD data based on the literature review which reveals current concerns of decision functions in the supply chain. The implications can be an impact to the domain needs.

description: We consider cases where the dark matter-nucleon interaction is naturally suppressed. We explicitly show that by extending the standard model scalar sector by a number of singlets, can lead to a vanishing direct detection cross section, if some softly broken symmetries are imposed in the dark sector. In particular, it is shown that if said symmetries are $SU(2)$ ($SU(N)$) and $U(1) \times S_N$, then the resulting pseudo-Nambu-Goldstone bosons can constitute the dark matter of the Universe, while naturally explaining the missing signal in nuclear recoil experiments.

description: Twisted 2D layered materials have garnered a lot of attention recently as a class of 2D materials whose interlayer interactions and electronic properties are dictated by the relative rotation / twist angle between the adjacent layers. In this work, we explore a prototype of such a twisted 2D system, artificially stacked twisted bilayer graphene (TBLG), where we probe the changes in the interlayer interactions and electron-phonon scattering pathways as the twist angle is varied from 0° to 30°, using Raman spectroscopy. The long range Moiré potential of the superlattice gives rise to additional intravalley and intervalley scattering of the electrons in TBLG which have been investigated through their Raman signatures. The density functional theory (DFT) calculations of the electronic band structure of the TBLG superlattices was found to be in agreement with the resonant Raman excitations across the van Hove singularities in the valence and conduction bands predicted for TBLG due to hybridization of bands from the two layers. We also observe that the relative rotation between the graphene layers has a marked influence on the second order overtone and combination Raman modes signalling a commensurate-incommensurate transition in TBLG as the twist angle increases. This serves as a convenient and rapid characterization tool to determine the degree of commensurability in TBLG systems.

description: In der vorliegenden Arbeit wurde der Zusammenhang zwischen der Einleitung von kommunalen Kläranlagen und der Menge an Antibiotikaresistenzgenen (ARG) in Flusssedimenten des Vorfluters untersucht. Eine wesentliche Frage war dabei, was der Treiber für die Akkumulation der ARG ist. Zur Auswahl standen dabei die Einleitungen von Antibiotikarückständen (ABs) auf der einen Seite oder die partikuläre Fracht auf der anderen Seite. Letztere ist dafür bekannt, pathogene Organismen aber auch ARG mit sich zu führen. Die Ergebnisse einer Feldstudie zeigten zunächst, dass die Selektion von ARG durch Antibiotikarückstände möglicherweise weniger entscheidend ist, als allgemein angenommen wird. Stattdessen wiesen sie auf die zweite der oben benannten Optionen für die Verbreitung von ARG hin: ARG (ermB, blaTEM, tetM, qnrS) assoziieren zum Teil stark mit den partikulären Bestandteilen im Abwasser und gelangen damit über die Sedimentation in das Sediment der Vorfluter. Die ARG-Menge in der sedimentierbaren Fraktion von Abwasser (Genkopien pro g Schwebstoffe, engl. total suspended solids, TSS) korrelierte dabei positiv mit der Änderung der ARG-Menge im Flusssediment des Vorfluters (Differenz der Genkopien pro g Sediment unterhalb und oberhalb der Einleitungsstelle) (R² = 0,93; p

description: We present the full O(alpha_s) longitudinal spin-spin correlations for heavy-quark pair production at e+ e- high-energy colliders in closed analytical form. In such reactions, quark and antiquark have strongly correlated spins, and the longitudinal components are dominant. For the explicit computation of the QCD bremsstrahlung contributions, new phase-space integrals are derived. Explicit numerical estimates are given for t t_bar and b b_bar production. Around the Z-peak, QCD one-loop corrections depolarize the spin-spin asymmetry for bottom quark pairs by approximately -4%. For top pair production, we find at 350GeV a 0.6% increased polarization over a value of 0.4 in the longitudinal correlation. For more than 1 TeV the O(alpha_s) corrections enhance depolarization to -2% in the top-pair case.

We present explicit convergence results in total variation or weighted total variation norms (alternatively $L^1$ or weighted $L^1$ norms). The convergence rates are exponential when the equations are posed on the torus, or with a confining potential growing at least quadratically at infinity. Moreover, we give algebraic convergence rates when subquadratic potentials considered. We use a method from the theory of Markov processes known as Harris's Theorem.

description: The 2004-2010 VQR, completed in July 2013, was Italy's second national research assessment exercise. The VQR performance evaluation followed a pattern also seen in other nations, in being based on a selected subset of products. In this work we identify the exercise's methodological weaknesses and measure the distortions that result from them in the university performance rankings. First we create a scenario in which we assume the efficient selection of the products to be submitted by the universities and from this simulate a set of rankings applying the precise VQR rating criteria. Next we compare these "VQR rankings" with those that would derive from application of more appropriate bibliometrics. Finally we extend the comparison to university rankings based on the entire scientific production for the period, as indexed in the Web of Science.

description: Dark matter-baryon scaling relations in galaxies are important in order to constrain galaxy formation models. Here, we provide a modern quantitative assessment of those relations, by modelling the rotation curves of galaxies from the Spitzer Photometry and Accurate Rotation Curves (SPARC) database with the Einasto dark halo model. We focus in particular on the comparison between the original SPARC parameters, with constant mass-to-light ratios for bulges and disks, and the parameters for which galaxies follow the tightest radial acceleration relation. We show that fits are improved in the second case, and that the pure halo scaling relations also become tighter. We report that the density at the radius where the slope is -2 is strongly anticorrelated to this radius, and to the Einasto index. The latter is close to unity for a large number of galaxies, indicative of large cores. In terms of dark matter-baryon scalings, we focus on relations between the core properties and the extent of the baryonic component, which are relevant to the cusp-core transformation process. We report a positive correlation between the core size of halos with small Einasto index and the stellar disk scale-length, as well as between the averaged dark matter density within 2 kpc and the baryon-induced rotational velocity at that radius. This finding is related to the consequence of the radial acceleration relation on the diversity of rotation curve shapes, quantified by the rotational velocity at 2 kpc. While a tight radial acceleration relation slightly decreases the observed diversity compared to the original SPARC parameters, the diversity of baryon-induced accelerations at 2 kpc is sufficient to induce a large diversity, incompatible with current hydrodynamical simulations of galaxy formation, while maintaining a tight radial acceleration relation.

Evolution of Cold Streams in the CGM of Massive Galaxies and Proto-Clusters at high-z
Creators: name: Mandelker, Nir
Publisher: name: Zenodo
Year: 2021

description: Massive star-forming galaxies and proto-clusters at high redshift, z>2, are thought to be fed by narrow streams of cold, ~10^4K, gas from cosmic web filaments. However, the interaction of these cold streams with the ambient hot CGM is poorly understood. In particular, the observational signatures of this interaction and of cold streams more broadly, the thermal and morphological state of the gas that eventually reaches the central galaxy, and its effect on galaxy evolution, are all open questions. I will present the latest results from a systematic study of this interaction, using a combination of analytic models, idealized high-resolution numerical simulations, and comsological simulations. We study the effects of hydrodynamics, radiative cooling, self-gravity, the halo potential, and magnetic fields, separately and in tandem, in order to gain insight into stream evolution in different limits.
 We find that while hydrodynamic instabilities can disrupt streams in the CGM, these are stabilized by cooling, gravity, and MHD. Radiative cooling in the turbulent mixing layer between the stream and the CGM is observable in Lyman alpha, and can explain several observed Lyman alpha blobs. Self-gravity in the streams can lead to star-formation in the CGM at redshifts z>~4. MHD effects lead to magnetically dominated interface regions which appear out of thermal pressure equilibrium and impact the phase structure of the high-z CGM.

description: The densities in the cores of the neutron stars (NSs) can reach several times that of the nuclear saturation density. The exact nature of matter at these densities is still virtually unknown. We consider a number of proposed, phenomenological relativistic mean-field equations of state to construct theoretical models of NSs. We find that, based on our selected set of models, the emergence of exotic matter at these high densities restricts the mass of NSs to $\simeq 2.2 M_\odot$. However, the presence of magnetic fields and a model anisotropy significantly increases the star's mass, placing it within the observational mass gap that separates the heaviest NSs from the lightest black holes. Therefore, we propose that gravitational wave observations, like GW190814, and other potential candidates within this mass gap, may actually represent massive, magnetized NSs.

Lambda_b are selected by the presence of energetic Lambda particles in bottom events tagged by the presence of displaced secondary vertices. A fit to the momenta of the Lambda particles separates signal from B meson and fragmentation backgrounds. The measured product branching ratio is f(b->Lambda_b).BR(Lambda_b->Lambda X) = (2.67+-0.38(stat)+0.67-0.60(sys))% Combined with a previous OPAL measurement, one obtains f(b->Lambda_b).BR(Lambda_b->Lambda X) = (3.50+-0.32(stat)+-0.35(sys))%.

description: The research aimed to identify changes in the level of liquidity and profitability of meat industry enterprises and determine the relationship between liquidity and profitability in this industry. The authors made a hypothesis that there is a positive relationship between the liquidity and profitability of meat enterprises, which means that along with the increase in financial liquidity the profitability of enterprises increased. The research used information from meat processing and preservation companies, except poultry, employing more than nine persons. The analysis covered companies that were obliged to submit financial statements to the National Court Register. In 2007, there were 467 such enterprises in Poland and 316 in 2018. The descriptive statistics, Pearson correlation coefficient, and linear regression analysis were used in the data analysis. The analyses show that the number of meat businesses in Poland is decreasing as a result of their consolidation and winding-up due to the difficult financial situation. The average current liquidity ratio of the enterprises analyzed between 2007 and 2018 remained at a satisfactory level from 1.054 to 1.49. The research shows a significant correlation between current and quick liquidity ratios and returns on assets and equity. The highest level of correlation occurred between the quick liquidity ratio and the asset profitability ratio. The profitability of meat enterprises in the long term is associated with maintaining financial liquidity. In turn, maintaining the ability to meet current obligations requires a rational management of profit and working capital.

Analysis of the resulting series yields an improved estimate, $τ= 4.062570(8)$, for the growth constant of lattice animals and confirms to a very high degree of certainty that the generating function has a logarithmic divergence. We prove the bound $τ> 3.90318.$ We also calculate the radius of gyration of both lattice animals and polygons enumerated by area. The analysis of the radius of gyration series yields the estimate $ν= 0.64115(5)$, for both animals and polygons enumerated by area. The mean perimeter of polygons of area $n$ is also calculated. A number of new amplitude estimates are given.

description: Wind actions can have a great impact on both bridges and traffic on bridges. However, structures designed to shelterthe traffic from wind can influence the aerodynamic performance of the bridge deck, especially for long-span bridges. This study compares the effect of non-perforated walls and perforated walls used as wind barriers for traffic by conducting Computational Fluid Dynamics (CFD) simulations on three-dimensional geometries of a four-lane bridge deck. Steady-state simulations employ the Reynolds-Averaged Navier Stokes (RANS) method with the k-epsilon turbulence model and all simulations use parallel computing. An open-sourced software OpenFOAM is used.

description: The $^{12}$C($α,γ$)$^{16}$O reaction, an important component of stellar helium burning, plays a key role in nuclear astrophysics. It has direct impact on the evolution and final state of massive stars, while also influencing the elemental abundances resulting from nucleosynthesis in such stars. Providing a reliable estimate for the energy dependence of this reaction at stellar helium burning temperatures has been a major goal for the field. In this work, we study the role of potential new measurements of the inverse reaction, $^{16}$O($γ,α$)$^{12}$C, in reducing the overall uncertainty. A multilevel R-matrix analysis is used to make extrapolations of the astrophysical S factor for this reaction to the stellar energy of 300 keV. The statistical precision of the S-factor extrapolation is determined by performing multiple fits to existing E1 and E2 ground state capture data, including the impact of possible future measurements of the $^{16}$O($γ,α$)$^{12}$C reaction. In particular, we consider a proposed JLab experiment that will make use of a high-intensity low-energy bremsstrahlung beam that impinges on an oxygen-rich single-fluid bubble chamber in order to measure the total cross section for the inverse reaction. The importance of low energy data as well as high precision data is investigated.

description: In this paper we consider classical and quantum versions of the critical long-range $O(N)$ model, for which we study finite-size and finite-temperature effects, respectively, at large $N$. First, we consider the classical (isotropic) model, which is conformally invariant at criticality, and we introduce one compact spatial direction. We show that the finite size dynamically induces an effective mass and we compute the one-point functions for bilinear primary operators with arbitrary spin and twist. Second, we study the quantum model, mapped to a Euclidean anisotropic field theory, local in Euclidean time and long-range in space, which we dub \emph{fractional Lifshitz field theory}. We show that this model admits a fixed point at zero temperature, where it displays anisotropic Lifshitz scaling, and show that at finite temperature a thermal mass is induced. We then compute the one-point functions for an infinite family of bilinear scaling operators. In both the classical and quantum model, we find that, as previously noted for the short-range $O(N)$ model in [arXiv:1802.10266], the large-$N$ two-point function contains information about the one-point functions, not only of the bilinear operators, but also of operators that appear in the operator product expansion of two fundamental fields only at subleading order in $1/N$, namely powers of the Hubbard-Stratonovich intermediate field.

Final-state Interaction Effects on Inclusive Two-particle Production in Electron-positron Annihilation

description: The final-state interaction effects on the inclusive two-particle production in electron-positron annihilation are investigated within the context of the one-photon annihilation approximation. Such effects are characterized by one structure function in the decomposition of the hadronic tensor. On the basis of the positivity, we derived an inequality to bound this structure function. The price to access it experimentally is to polarize longitudinally one of the initial-state beam, to say, the electron beam, and measure the corresponding single spin asymmetry. By combining the Callan-Gross relation with our positivity analysis, we obtain an upper bound for the single spin asymmetry considered.

description: COSINE-100 is a dark matter direct detection experiment with 106 kg NaI(Tl) as the target material. 210Pb and daughter isotopes are a dominant background in the WIMP region of interest and are detected via beta decay and alpha decay. Analysis of the alpha channel complements the background model as observed in the beta/gamma channel. We present the measurement of the quenching factors and Monte Carlo simulation results and activity quantification of the alpha decay components of the COSINE-100 NaI(Tl) crystals. The data strongly indicate that the alpha decays probabilistically undergo two possible quenching factors but require further investigation. The fitted results are consistent with independent measurements and improve the overall understanding of the COSINE-100 backgrounds. Furthermore, the half-life of 216Po has been measured to be 143.4 +/- 1.2 ms, which is consistent with and more precise than recent measurements.

description: Purpose: Radiation therapy is an integral part of current treatment modality for colorectal cancer. Recent studies have revealed the presence of cancer stem-like cells (CSCs) population, in different tumors are responsible for therapeutic resistance and disease relapse, including colorectal cancer with poorer survival rate. Hence, characterization of the effect of Ionizing Radiation (IR) in colorectal cancer may serve to explain possible mechanisms. Material and methods: Parental HCT116 and HCT-15 cells and derived colonospheres were irradiated and dose was optimized based on cell survival assay and cell cycle analysis. DNA damage response (DDR) was elucidated by γH2AX foci formation, COMET assay, and ATM, p-ATM, ERCC1 expression post-treatment. The expression level of developmental marker (β-catenin), CSC markers (CD44, KLF4) and telomeric components (TRF2, RAP1, hTERT) were evaluated. Results: We observed cell survival was more in colonospheres post-irradiation and also exhibited decreased γH2AX foci, olive tail moment, increased ERCC1, and p-ATM expression than its parental counterpart which corresponds to efficient DDR. Differential expression of developmental marker, CSC markers, and telomeric components were observed after irradiation. Conclusion: This study highlighted the presence of CSC phenotype in colonospheres having increased DNA repair capacity. Differential expression of developmental marker, CSC markers and telomeric components between parental and colonospheres may contribute in radio-resistance property of CSCs.

description: This paper examines the Sales-Forecast system and the Theil-Wage model, on the basis of which a forecast for the sale of sneakers is built. To simplify calculations, the raw statistics are logarithmized, converting the exponential trend of the Theil-Wage model to linear and the multiplicative seasonal model to additive. For each model, a geometric interpretation of the obtained results is carried out, the average approximation error and the relative prediction error are found. At the end of the study, a comparative analysis of the constructed forecasts is carried out. Calculations of intermediate values and construction of a forecast are implemented in Microsoft Excel.

description: One of the traditional applications of relation algebras is to provide a setting for infinite-domain constraint satisfaction problems. Complexity classification for these computational problems has been one of the major open research challenges of this application field. The past decade has brought significant progress on the theory of constraint satisfaction, both over finite and infinite domains. This progress has been achieved independently from the relation algebra approach. The present article translates the recent findings into the traditional relation algebra setting, and points out a series of open problems at the interface between model theory and the theory of relation algebras.

Tunneling into a periodically modulated Luttinger liquid

Year: 1996
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: We study the tunneling into the edge of the Luttinger liquid with periodically modulated concentration of electrons. It is shown that the modulation,by causing a gap in the spectrum of plasmons, leads to an additional anomaly in the density of states at frequency corresponding to the center of the gap. The shape of the anomaly depends strongly on the {\em phase} of the modulation. The sensitivity to the phase is related to the plasmon mode, localized at the edge, its frequency lying within the gap (analog of the Tamm state for an electron in an interrupted periodic potential).
