description: We determine the curvature of the (pseudo)critical line of QCD with $n_f$=2+1 staggered fermions at nonzero temperature and quark density, by analytic continuation from imaginary chemical potentials. Monte Carlo simulations are performed adopting the HISQ/tree action discretization, as implemented in the code by the MILC collaboration, suitably modified to include a nonzero imaginary baryon chemical potential. We work on a line of constant physics, as determined in Ref.\cite{Bazavov:2011nk}, adjusting the couplings so as to keep the strange quark mass $m_s$ fixed at its physical value, with a light to strange mass ratio $m_l/m_s=1/20$. In the present investigation we set the chemical potential at the same value for the three quark species, $μ_l=μ_s\equiv μ$. We explore lattices of different spatial extensions, $16^3\times 6$ and $24^3\times 6$, to check for finite size effects, and present results on a $32^3 \times 8$ lattice, to check for finite cut-off effects. We discuss our results for the curvature $κ$ of the critical line at $μ= 0$, which indicate $κ=0.018(4)$, and compare them with previous lattice determinations by alternative methods and with experimental determinations of the freeze-out curve.

description: We study mode competition in a multimode "phonon laser" comprised of an optical cavity employing a highly reflective membrane as the output coupler. Mechanical gain is provided by the intracavity radiation pressure, to which many mechanical modes are coupled. We calculate the gain, and find that strong oscillation in one mode suppresses the gain in other modes. For sufficiently strong oscillation, the gain of the other modes actually switches sign and becomes damping, a process we call "anomalous cooling." We demonstrate that mode competition leads to single-mode operation and find excellent agreement with our theory, including anomalous cooling.

HPA nuclei segmentation model This is the official baseline nuclei segmentation model provided to the participants of the Human Protein Atlas - Single Cell Classification competition held in 2021. The model is a DPN-Unet adopted from the top winning model of 2018 Data Science Bowl competition for nuclei segmentation. It's a U-Net variation predicting a two-channel border mask. See here for more details. In this implementation, the same DPN-Unet model was trained on around 300 cell images from the Human Protein Atlas with slightly different post processing. The full training dataset along with the trained weights were published at https://zenodo.org/record/4430893. To run this baseline model with the orignal pytorch weigths, see hpa cell segmentator. This model is used for nuclei segmentation and can be used together with the cell segmentation model published at: https://zenodo.org/record/6200636

description: We present unified approach to different recent entanglement criteria. Although they were developed in different ways, we show that they are all applications of a more general principle given by the Cauchy-Schwarz inequality. We explain this general principle and show how to derive with it not only already known but also new entanglement criteria. We systematically investigate its potential and limits to detect bipartite and multipartite entanglement.

description: About 22 percent of the nation's milk is produced by farmers in the Northeast, the 12-State area from Maine through Virginia. Although oriented toward the fluid milk market, these markets have carried large volumes of reserve supplies which are used in manufactured dairy products. Changes in the population, in the level of milk production, and the relative production of different areas result in marked adjustments in the utilization of milk in different products. Changes in sales and utilization are compared with production in the area in 1960, with total milk production in the area, and presented as a percentage of the total Northeast and U.S. production. Counties were described according to certain characteristics affecting milk production and utilization. The counties were then grouped according to similarities and compared. Increasing population and falling milk production near metropolitan areas combine to increase the need for shipping milk into these population centers.

description: Berry phases occur when a system adiabatically evolves along a closed curve in parameter space. This tutorial-like article focuses on Berry phases accumulated in real space. In particular, we consider the situation where an electron traverses a smooth magnetic structure, while its magnetic moment adjusts to the local magnetization direction. Mapping the adiabatic physics to an effective problem in terms of emergent fields reveals that certain magnetic textures - skyrmions - are tailormade to study these Berry phase effects.

description: This report analyzes the shortrun economic impact of a tissue paper mill on Pickens, Miss., a town of under 1,000 in a depressed rural area with a predominance of poor Negroes. The tissue mill began in a building formerly occupied by a North Carolina furniture manufacturer. Initial financing came from the Area Redevelopment Administration, local and State organizations, and private industry. Failure of the operation was attributed to lack of skilled employees, frequent breakdowns of secondhand machinery, variability in the quality of wet pulp, and an inadequately developed market. After foreclosure by the Small Business Administration, the plant was leased to another company to produce carbonizing paper used by that company. The case raises many questions about the development of such a depressed rural area.
The Effect of Mergers and Acquisitions on the Management of Intellectual Property: A case of the European Chemical Industry
Creators: name: Adetona, Adebola
Publisher: name: Leeds Beckett University
Year: 2022
Subjects: Uncategorized

description: Mergers and acquisitions (M&A) have become an essential business tool in a global marketplace characterised by the increasing importance of intellectual property (IP) assets. Due to modern innovative techniques and recent technological advancements, IP now forms a significant proportion of a company's assets. Compared to other industries, firms in the chemical industry constantly generate IP assets, making IP the driving force for creating value within the industry. With the significant expansion of M&A activity ongoing within the industry, IP continues to drive the industry for growth, strategic change, and consolidation. Besides the increasing M&A activity, a more complicated set of dynamics of high M&A failure rate is at work, particularly within the European Union (EU) chemical industry, where the average failure rate sits at 70-90%. Drawing on practice based theory and insights from studies on IP and its management, this study investigates the pre and post- M&A IP management practices of merged chemical firms in the EU to understand the effect of M&A on IP management practices and its implication for M&A success. Thirty-four semi-structured interviews with seven European chemical firms were conducted using a mixed-methods approach. Two face-to-face and three telephone interviews and twenty-nine written responses to the interview questionnaire. Through mainly qualitative data analysis methods of elicitation, observations, document review, and consideration of events surrounding the effect of M&A on IP management practices, the effect of M&A on IP management practices was investigated. Pre- and post- M&A intellectual property management practices of the chemical firms were identified and reviewed, following a developed intellectual property management development process (IPMDP) and an intellectual property management practice (IPMP) model. This study finds that having an intellectual property plan and model is critical to improving due diligence in M&A transactions. It finds that employing and involving IP management experts and including a communication and employee training and development strategy in M&A processes can increase the success of M&A transactions. Based on interpretivists’ objective of gaining understanding, this study contributes to a practice-based view on IP management that the most critical M&A success solution involves firms understanding their IP management practice requirements in M&A.
Solar wind dominance over the Poynting-Robertson effect in secular orbital evolution of dust particles

Year: 2014
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: Properties of the solar wind are discussed and applied to the effect of the wind on motion of bodies in the Solar System. The velocity density function for the solar wind constituents is given by the $κ-$distribution. The relevant contributions to the solar wind action contain also the sputtering and reflection components in addition to direct impact. The solar wind effect is more important than the action of the solar electromagnetic radiation, as for the secular orbital evolution. The effect of the solar corpuscular radiation is more important than the Poynting-Robertson effect even when mass of the dust particle is considered to be constant, non-radial component of the solar wind velocity is neglected and the time dependence of the solar wind properties is ignored. The presented equation of motion of a body under the action of the solar radiation, electromagnetic and corpuscular, respects reality in a much better way than the conventionally used equation. The acceleration of the body is proportional to the superposition of the radial velocity component multiplied by the numerical coefficient $[2 + (η_{1} + η_{2})/ \overline{Q} ~'_{pr}]$ and the transversal velocity component multiplied by the numerical coefficient $(1 + η_{2}/ \overline{Q} ~'_{pr})$, where $\overline{Q} ~'_{pr}$ is the dimensionless efficiency factor of the radiation pressure. Here $η_{1}$ $\doteq$ 1.1, $η_{2}$ $\doteq$ 1.4 and the velocity is the body's velocity with respect to the Sun. Also time variability of $η_{1}$ and $η_{2}$ due to the solar cycle is given. The dimensionless cross section the dust grain presents to wind pressure is about 4.7. This value differs from the conventionally used value 1.0. The mass-loss rate of the zodiacal cloud is 4-times higher than the currently accepted value, as for the micron-sized dust particles.

description: We describe a numerical investigation of a continuum model of an active nematic, concentrating on the regime of active turbulence. Results are presented for the effect of three parameters, activity, elastic constant and rotational diffusion constant, on the order parameter and flow fields. Defects and distortions in the director field act as sources of vorticity, and thus vorticity is strongly correlated to the director field. In particular the characteristic length of decay of vorticity and order parameter correlations is controlled by the defect density. By contrast the decay of velocity correlations is determined by a balance between activity and dissipation. We highlight the role of microscopic flow generation mechanisms in determining the flow patterns and characteristic scales of active turbulence and contrast the behaviour of extensile and contractile active nematics.

description: Fifty-five percent of the 392 million acres of farmland rented in 1964 were rented for cash. Between 1961 and 1968, gross cash rents per acre increased at a slower rate than land values; landlord expenditures per acre also increased. Thus, net rents moved up even more slowly than gross rents and rent-to-value ratios declined. Cash renting is increasing in the United States, in part because of increased renting by part owners, who tend to use cash leases more frequently than do full tenants. The increase in farm size and capital needs that is associated with a continuing trend toward part ownership and what appears to be a general shift from share renting implies a greater reliance on cash renting in the future. The report also describes methodology used in determining the acreage of cash-rented land.

description: Short millimeter observations of radio-loud AGN offer the opportunity to study the physics of their inner relativistic jets, from where the bulk millimeter emission is radiated. Millimeter jets are significantly less affected by Faraday rotation and depolarization than in radio. Also, the millimeter emission is dominated by the innermost jet regions, that are invisible in radio owing to synchrotron opacity. We present the first dual frequency simultaneous 86GHz and 229GHz polarimetric survey of all four Stokes parameters of a large sample of 211 radio loud active galactic nuclei, designed to be flux limited at 1Jy at 86GHz. The observations were most of them made in mid August 2010 using the XPOL polarimeter on the IRAM 30 m millimeter radio telescope. Linear polarization detections above 3 sigma median level of ~1.0% are reported for 183 sources at 86GHz, and for 23 sources at 229GHz, where the median 3 sigma level is ~6.0%. We show a clear excess of the linear polarization degree detected at 229GHz with regard to that at 86GHz by a factor of ~1.6, thus implying a progressively better ordered magnetic field for blazar jet regions located progressively upstream in the jet. We show that the linear polarization angle, both at 86 and 229GHz, and the jet structural position angle for both quasars and BL Lacs do not show a clear preference to align in either parallel or perpendicular directions. Our variability study with regard to the 86GHz data from our previous survey points out a large degree variation of total flux and linear polarization in time scales of years by median factors of ~1.5 in total flux, and ~1.7 in linear polarization degree -maximum variations by factors up to 6.3, and ~5, respectively-, with 86% of sources showing linear polarization angles evenly distributed with regard to our previous measurements.

description: We propose a one-dimensional electron model with parameters modulated adiabatically in closed cycles, which can continuously pump spin to leads. By defining the spin-polarized Wannier functions, we show that the spin pump is protected by the spin Chern numbers, so that it is stable to perturbations violating the time-reversal symmetry and spin conservation. Our work demonstrates the possibility and principle to realize topological spin pumps independent of any symmetries, and also suggests a possible way to experimentally observe the bulk topological invariants.

description: The establishment of new manufacturing plants in five towns in Kentucky had a negative net fiscal impact on most local governmental units during 1958-63, Inmost of the counties studied, the direct effect of locating the new manufacturing plants in the small towns was to increase the costs of government for the School district and often the town without increasing the revenue. The increases were typically small, however. Also, a comparison of the study counties with a group of comparable counties that had no new industry added during the study period showed no significant differences between the two groups of counties in changes in local governmental revenue or expenditures due to any secondary effects of new industry in the study counties.
Integrating in vivo crystallography and de novo protein design at the Nagoya University platform
Creators: name: Chavas, Leonard
Publisher: name: Zenodo
Year: 2023

description: In recent years, in vivo macromolecular crystallography (ivMX) has gained attention for studying protein crystals occurring naturally within cells and organisms. ivMX, also known as in cellulo MX, offers unique opportunities for high-throughput pipelines and workflow transformation by bypassing sample purification and crystallization steps. This eliminates the need for extensive protein preparation, as organisms perform these processes. Additionally, ivMX enables the study of proteins with post-translational modifications, which are often neglected in in vitro MX studies. 
 
Global research groups have made significant progress in understanding the unpredictable events governing natural crystal growth. Synchrotron SOLEIL in France has been crucial in initiating investigations into ivMX phenomena. Building upon this progress, Nagoya University has integrated the ivMX platform into the Next-BINDS national project, facilitating broader access and collaborative research, particularly in Japan.
 
This study presents the latest developments in the integrated ivMX platform, now open for project proposals. Our objectives include advancing the automation of the ivMX pipeline and streamlining sample handling, data collection, and analysis. We also aim to integrate de novo protein design techniques with ivMX, exploring protein structures beyond nature. By combining in vivo crystal growth and rational protein engineering, we anticipate breakthroughs in understanding structure-function relationships and novel applications in various scientific disciplines.
 
The integration of the ivMX platform at Nagoya University marks an exciting phase in in vivo protein crystal research. We invite researchers from diverse backgrounds to leverage this platform for their investigations. Together, we can unlock the full potential of ivMX, accelerating discoveries, and pioneering innovative approaches in structural biology and protein engineering.

description: This report provides information on pesticide expenditures by U.S. farmers in 1966 and some comparisons with 1964. Data are based on a survey conducted in 1967 to measure pesticide use by farmers in 1966. Expenditures for pesticides in crop and livestock production and for other purposes are examined. Expenditures are also reported by type of pesticide, including fungicides, herbicides, insecticides, and several others. The study is based on a survey of about 9,600 farmers throughout the United States, excluding Alaska and Hawaii. Survey data were expanded to represent regional and U.S. expenditures for pest control on farms. Findings show that farmers' total pesticide expenditures were $561 million in 1966, with almost $506 million spent for crop protection alone. Herbicides were 48 percent of total crop pesticide expenditures, insecticides were more than 38 percent, and fungicides were close to 7 percent. Total pesticide expenditures for crop production in 1966 exceeded those in 1964 by 17 percent. The total cost for pesticides used on livestock and their surroundings was over $29 million, about the same as in 1964. Pesticide costs for other farm uses amounted to $26 million.

description: The quality of rural housing has improved markedly since World War II; from 38 percent standard in 1950 to 67 percent in 1960 and nearly 80 percent in 1968. Rural housing has shared in the general upgrading of housing which resulted from the postwar building boom. New construction and renovation has exceeded new household formations by a wide enough margin to permit a general shifting up and abandonment or demolition of the poorest units. Rural America however, still had higher percentages of substandard housing than did urban areas in 1968: 17.1 percent of nonmetropolitan housing was substandard compared, with 5.7 percent in the central cities of the SMSA's and 4.0 percent outside the central cities of the SMSA’s. The substandard rural housing is heavily concentrated in the southeastern States. The analysis emphasizes rural aspects of the private sector construction industry, mobile homes, the financing of housing, government programs, and projections.

description: Molybdenum and nitrogen co-doped $TiO_2$ nanotube arrays (TNAs) were prepared by anodizing in association with hydrothermal treatment. As-prepared Mo and N co-doped TNAs were characterized by field emission scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy and ultraviolet-visible light diffuse reflection spectroscopy. Besides, the photocatalytic activity of Mo and N co-doped TNAs for the degradation of methylene blue (denoted as MB) under visible light irradiation was evaluated. It was found that N in co-doped TNAs coexists in the forms of N-Ti-O and N-O-Ti, while Mo exists as $Mo^{6+}$ by substituting Ti in the lattice of $TiO_2$. In the meantime, Mo and N co-doping extends the absorption of TNAs into the whole visible light region and results in remarkably enhanced photocatalytic activity for the degradation of MB under visible light irradiation. This could be attributed to the synergetic effect between Mo-doping and N-doping. Namely, Mo and N passivated co-doping produces new states in TNAs, thereby narrowing the bandgap and decreasing the recombination rate of electrons and holes. As a result, the visible light absorption and photocatalytic activity of TNAs is greatly increased. Furthermore, Mo ions with multiple valences in all co-doped samples could act as trapping sites to effectively decrease the recombination rate of electrons and holes, which also contribute to improved photocatalytic activity of Mo and N co-doped TNAs. Keywords: TiO2 Nanotube Arrays, Mo, N, Co-Doping, Photocatalytic Activity.

description: The regularized vacuum fluctuation related to a conformally coupled massless scalar field defined on a space-time with dynamical horizon is computed with respect a radially moving observer in a generic flat Friedmann-Robertson-Walker space-time. Two simple measurement prescriptions are given in order to remove the ambiguity associated with the short distance singularity of the correlation function. In some cases, it turns out that one is dealing with a quantum thermometer, recovering a proposal due to Buchholzet al. in order to determine local temperature in the framework of quantum field theory. In general, by arranging the detector so that it does not register for inertial motion in flat space, the regularized quantum fluctuation may be used as a probe of space-time geometry and, in particular, may provide informations on the Hubble parameter. As an aside, it is not possible in general to fully decouple the effect of the detector motion from the universe expansion, a fact that could be interpreted as a kind of Machian effect which can be traced back to the worldwide nature of the vacuum.

In the collective pinning regime, we compute the critical force perturbatively. Not only our expression for the critical force confirms previous results on its scaling with respect to the microscopic disorder parameters, it also provides its precise dependence on the disorder geometry (represented by the disorder two-point correlation function). Our results are successfully compared to the results of numerical simulations for random field and random bond disorders.

Net reductions in farm income would total $107 million for corn, $51 million for wheat, $8 million for rice, $28 million for other small grain, $11 million for sorghum, $33 million for pasture, $36 million for rangeland, and $16 million for other crops on which the phenoxys were used in 1966. The estimates were determined for each of the above crops by partial budgeting using cross-sectional data from the ERS Pesticide and General Farm Survey, 1966; Agricultural Statistics, 1968; and from Agricultural Research Service weed scientists.

description: The Sunyaev-Zel'dovich effect provides a useful probe of cosmology and structure formation in the Universe. Recent years have seen rapid progress in both quality and quantity of its measurements. In this review, we overview cosmological and astrophysical implications of recent and near future observations of the effect. They include measuring the evolution of the cosmic microwave background radiation temperature, the distance-redshift relation out to high redshifts, number counts and power spectra of galaxy clusters, distributions and dynamics of intracluster plasma, and large-scale motions of the Universe.

description: A necessary and sufficient condition for linear stability of inviscid parallel shear flow is formulated by developing a novel variational principle, where the velocity profile is assumed to be monotonic and analytic. It is shown that unstable eigenvalues of Rayleigh's equation (which is a non-selfadjoint eigenvalue problem) can be associated with positive eigenvalues of a certain selfadjoint operator. The stability is therefore determined by maximizing a quadratic form, which is theoretically and numerically more tractable than directly solving Rayleigh's equation. This variational stability criterion is based on the understandings of Krein signature for continuous spectrum and is applicable to other stability problems of infinite-dimensional Hamiltonian systems.

description: Purpose: Specific language impairment (SLI) is characterized by a delay in language acquisition despite a lack of other developmental delays or hearing loss. Genetics of SLI is poorly understood. The purpose of this study is to identify SLI genetic loci through family-based linkage mapping.Method: We performed genome-wide parametric linkage analysis in six families segregating with SLI. An age-appropriate standardized omnibus language measure was used to categorically define the SLI phenotype.Results: A suggestive linkage region replicated a previous region of interest with the highest logarithm of odds (LOD) score of 2.40 at 14q11.2-q13.3 in Family 489. A paternal parent-of-origin effect associated with SLI and language phenotypes on a nonsynonymous single nucleotide polymorphism (SNP) in NOP9 (14q12) was reported previously. Linkage analysis identified a new SLI locus at 15q24.3-25.3 with the highest parametric LOD score of 3.06 in Family 315 under a recessive mode of inheritance. Suggestive evidence of linkage was also revealed at 4q31.23-q35.2 in Family 300, with the highest LOD score of 2.41. Genetic linkage was not identified in the other three families included in parametric linkage analysis.Conclusions: These results are the first to report genome-wide suggestive linkage with a total language standard score on an age-appropriate omnibus language measure across a wide age range. Our findings confirm previous reports of a language-associated locus on chromosome 14q, report new SLI loci, and validate the pedigree-based parametric linkage analysis approach to mapping genes for SLI.

Un duplice approccio: cosa può fare Open Science per la valutazione (e la comunicazione scientifica in generale) e cosa può fare la valutazione per l'Open Science

Cosa non funziona nella comuncazione scientifica attuale: ritrattazioni, frodi, cartelli di citazioni, papermills...

Come può aiutare la Open Science: se l'intero processo è trasparente e tutti i passaggi sono disponibili, migliorano integrità e riproducibilità

La riforma della valutazione è in atto: COARA, chi ha firmato e cosa fa il capitolo nazionale

description: In this paper, we introduce the relevant concepts of $n$-ary multiplicative Hom-Nambu-Lie superalgebras and construct three classes of $n$-ary multiplicative Hom-Nambu-Lie superalgebras. As a generalization of the notion of derivations for $n$-ary multiplicative Hom-Nambu-Lie algebras, we discuss the derivations of $n$-ary multiplicative Hom-Nambu-Lie superalgebras. In addition, the theory of one parameter formal deformation of $n$-ary multiplicative Hom-Nambu-Lie superalgebras is developed by choosing a suitable cohomology.

description: For any thorough investigation of complex physical properties, as encountered in strongly correlated electron systems, not only single crystals of highest quality but also a detailed knowledge of the structural properties of the material are pivotal prerequisites. Here, we combine physical and chemical investigations on the prototypical heavy fermion superconductors CeIrIn${_5}$ and CeCoIn${_5}$ on atomic and macroscopic length scale to gain insight into their precise structural properties. Our approach spans from enhanced resolution X-ray diffraction experiments to atomic resolution by means of Scanning Tunneling Microscopy (STM) and reveal a certain type of local features (coexistence of minority and majority structural patterns) in the tetragonal HoCoGa$_5$-type structure of both compounds.

description: Returns moved up substantially in the last 7 years on migratory-sheep ranches in the Utah-Nevada study area, the top sheep- and wool-producing area of its kind in the United States. Generally, higher prices received for lambs, improved range conditions, increased market weights of lambs, and greater output per ranch were responsible for these favorable returns. Despite these economic advances, migratory-sheep ranchers look to the future with caution; they are primarily concerned about wool prices, availability of good herders, and the continued opportunity to graze the public domain.

description: Census of Agriculture data for selected years during 1949-64 indicate that longrun changes in Lake States dairying are related importantly to economic forces whose geographic impacts vary considerably. In the economic setting typified by large, expanding metropolitan areas, dairying is now declining in importance. In contrast, dairying is becoming more important beyond the sphere of urban-industrial expansion--over 30 miles from metropolitan areas. The net consequences over time of these changes are shifts from the metropolitan areas in the geographic distributions of the number of milk producers, milk cow numbers, and aggregate milk production.
An optimal penalty method for a hyperbolic system modeling the edge plasma transport in a tokamak

Publisher: name: arXiv
Year: 2014
Subjects: subject: Numerical Analysis (math.NA)
subject: FOS: Mathematics

description: The penalization method is used to take account of obstacles, such as the limiter, in a tokamak. Because of the magnetic confinement of the plasma in a tokamak, the transport occurs essentially in the direction parallel to the magnetic field lines. We study a 1D nonlinear hyperbolic system as a simplified model of the plasma transport in the area close to the wall. A penalization which cuts the flux term of the momentum is studied. We show numerically that this penalization creates a Dirac measure at the plasma-limiter interface which prevents us from defining the transport term in the usual distribution sense. Hence, a new penalty method is proposed for this hyperbolic system. For this penalty method, an asymptotic expansion and numerical tests give an optimal rate of convergence without spurious boundary layer. Another two-fields penalization has also been implemented and the numerical convergence analysis when the penalization parameter tends to $0$ reveals the presence of a boundary layer.

description: In this paper, we find an upper bound for the exponent of the Schur multiplier of a pair $(G,N)$ of finite $p$-groups, when $N$ admits a complement in $G$. As a consequence, we show that the exponent of the Schur multiplier of a pair $(G,N)$ divides $\exp(N)$ if $(G,N)$ is a pair of finite $p$-groups of class at most $p-1$. We also prove that if $N$ is powerfully embedded in $G$, then the exponent of the Schur multiplier of a pair $(G,N)$ divides $\exp(N)$.
