description: The ZEUS inclusive differential cross-section data from HERA, for charged and neutral current processes taken with e+ and e- beams, together with differential cross-section data on inclusive jet production in e+ p scattering and dijet production in γp scattering, have been used in a new NLO QCD analysis to extract the parton distribution functions of the proton. The input of jet data constrains the gluon and allows an accurate extraction of α_s(M_Z) at NLO; α_s(M_Z) = 0.1183 \pm 0.0028(exp.) \pm 0.0008(model) An additional uncertainty from the choice of scales is estimated as \pm 0.005. This is the first extraction of α_s(M_Z) from HERA data alone.

description: We propose a variational approach to explore quasiparticle excitations in interacting quantum many-body systems, motivated by the potential in leveraging near-term noisy intermediate scale quantum devices for quantum state preparation. By exploiting translation invariance and potentially other abelian symmetries of the many-body Hamiltonian, we extend the variational quantum eigensolver (VQE) approach to construct spatially localized quasiparticle states that encode information on the whole excited band, allowing us to achieve quantum parallelism. We benchmark the proposed algorithm via numerical simulations performed on the one-dimension transverse field Ising chain. We show that VQE can capture both the magnon quasiparticles of the paramagnetic phase, and the topologically non-trivial domain wall excitations in the ferromagnetic regime. We show that the localized quasiparticle states constructed with VQE contain accessible information on the full band of quasiparticles, and provide valuable insight into the way interactions renormalize the bare spin flip or domain wall excitations of the simple, trivially solvable limits of the model. These results serve as important theoretical input towards utilizing quantum simulators to directly access the quasiparticles of strongly interacting quantum systems, as well as to gain insight into crucial experimentally measured properties directly determined by the nature of these quasiparticles.

description: The BioReCer interview series showcases the different work packages and tasks within the BioReCer project in its quest to develop guidelines and recommendations for the certification of biobased feedstocks. 

This episode introduces Dr. Nadja Wulff (nova-Institute) and Christopher vom Berg (Renewable Carbon Initiative) who will explain the Biomass Utilisation Factor (BUF) and how it will be validaded in the BioReCer project.

BioReCer (Biological Resources Certifications Schemes) aims at assessing and complementing current certification schemes for biological resources according to the new EU sustainability goals to enhance bio-based circular systems.

This will be achieved by including new criteria that align with EU taxonomy and EU corporate due diligence regulations into guidelines for certifying biological resources’ sustainability, origin, tracking and traceability (T&T), and by ensuring applicability at EU and global scale.

By promoting the sustainability and trade of biological resources, BioReCer will increase the added value, use, as well as social acceptance of bio-based products.
Number ratios of young stellar objects in embedded clusters

description: Embedded clusters usually contain young stellar objects in different evolutionary stages. We investigate number ratios of objects in these classes in the star-forming regions rho Ophiuchi, Serpens, Taurus, Chamaeleon I, NGC 7129, IC 1396A, and IC 348. They are compared to the temporal evolution of young stars in numerical simulations of gravoturbulent fragmentation in order to constrain the models and to possibly determine the evolutionary stage of the clusters. It turns out that Serpens is the youngest, and IC 348 the most evolved cluster, although the time when the observations are best represented varies strongly depending on the model. Furthermore, we find an inverse correlation of the star formation efficiency (SFE) of the models with the Mach number. However, the observational SFE values cannot be reproduced by the current isothermal models. This argues for models that take into account protostellar feedback processes and/or the effects of magnetic fields.

description: In this paper, we study influence maximization in the voter model in the presence of biased voters (or zealots) on complex networks. Under what conditions should an external controller with finite budget who aims at maximizing its influence over the system target zealots? Our analysis, based on both analytical and numerical results, shows a rich diagram of preferences and degree-dependencies of allocations to zealots and normal agents varying with the budget. We find that when we have a large budget or for low levels of zealotry, optimal strategies should give larger allocations to zealots and allocations are positively correlated with node degree. In contrast, for low budgets or highly-biased zealots, optimal strategies give higher allocations to normal agents, with some residual allocations to zealots, and allocations to both types of agents decrease with node degree. Our results emphasize that heterogeneity in agent properties strongly affects strategies for influence maximization on heterogeneous networks.

Furthermore, a series of quantum-inspired information processing have been implemented by using classical electric circuit networks. In this review, we begin by analyzing the similarity between circuit Laplacian and lattice Hamiltonian, introducing topological physics based on classical circuits. Subsequently, we provide reviews of the research progress in quantum-inspired information processing based on the electric circuit, including discussions of topological quantum computing with classical circuits, quantum walk based on classical circuits, quantum combinational logics based on classical circuits, electric-circuit realization of fast quantum search, implementing unitary transforms and so on.

description: With their meaningful geometry and their omnipresence in the 3D world, edges are extremely useful primitives in computer vision. 3D edges comprise of lines and curves, and methods to reconstruct them use either multi-view images or point clouds as input. State-of-the-art image-based methods first learn a 3D edge point cloud then fit 3D edges to it. The edge point cloud is obtained by learning a 3D neural implicit edge field from which the 3D edge points are sampled on a specific level set (0 or 1). However, such methods present two important drawbacks: i) it is not realistic to sample points on exact level sets due to float imprecision and training inaccuracies. Instead, they are sampled within a range of levels so the points do not lie accurately on the 3D edges and require further processing. ii) Such implicit representations are computationally expensive and require long training times. In this paper, we address these two limitations and propose a 3D edge mapping that is simpler, more efficient, and preserves accuracy. Our method learns explicitly the 3D edge points and their edge direction hence bypassing the need for point sampling. It casts a 3D edge point as the center of a 3D Gaussian and the edge direction as the principal axis of the Gaussian. Such a representation has the advantage of being not only geometrically meaningful but also compatible with the efficient training optimization defined in Gaussian Splatting. Results show that the proposed method produces edges as accurate and complete as the state-of-the-art while being an order of magnitude faster.

description: O objetivo principal deste trabalho é propor uma nova configuração para o território brasileiro, fornecendo uma relevante dimensão para análise das desigualdades sociais brasileiras. A hipótese central é que a estrutura social, uma conjugação entre inserção no mercado de trabalho (classe ocupacional) e faixa de renda per capita (estrato social) das famílias brasileiras, é capaz de identificar padrões sociais que cumprem papel essencial nas análises sobre as condições de vida da população. Para cumprir tal objetivo, este trabalho foi estruturado em três partes principais: i) descrição da metodologia de estratificação social; ii) identificação dos grupos de municípios relativamente homogêneos de desenvolvimento da estrutura social (perfis sociais) e análise espacial desta configuração; iii) análise das desigualdades territoriais brasileiras utilizando o perfil social como variável de controle.---------------------------------------------The main purpose of this work is to propose a new configuration of Brazilian territory, providing a relevant dimension to the analysis of Brazilian social inequalities. The central hypothesis is that the social structure, which consists of a combination between job market (socio-occupational class) and per capita income band (socioeconomic segment) of Brazilian families, is capable of identifying social patterns which has an essential role in analysis of the life conditions of population. To reach such purpose, this work is structured in tree mains divisions: i) a description of the social stratification methodology; ii) identifying groups of relative homogeneity of social structure development (socials profiles) and spatial analysis of this configuration; iii) analysis of Brazilian territory inequalities using the social profile as control variable.

description: Superconformal Ward identities are derived for the the four point functions of chiral primary BPS operators for $\N=2,4$ superconformal symmetry in four dimensions. Manipulations of arbitrary tensorial fields are simplified by introducing a null vector so that the four point functions depend on two internal $R$-symmetry invariants as well as two conformal invariants. The solutions of these identities are interpreted in terms of the operator product expansion and are shown to accommodate long supermultiplets with free scale dimensions and also short and semi-short multiplets with protected dimensions. The decomposition into $R$-symmetry representations is achieved by an expansion in terms of two variable harmonic polynomials which can be expressed also in terms of Legendre polynomials. Crossing symmetry conditions on the four point functions are also discussed.

description: The Czech Republic entered the crisis with relatively good starting conditions - showed no significant macroeconomic imbalances and financial system was not destabilized. However, the crisis has here also been and a decline in GDP in 2009 to 4.1% was mainly due to economic recession in the Euro zone. In many countries there has been a change in the sector scope. The Czech Republic belongs to the industrial-oriented countries and the significance of recession is also demonstrated by the development of industrial production and exports. Further economic increase depends mainly on exports, because there are many industries in the Czech Republic with foreign majority and a large part of their production goes abroad. Czech agriculture has been also facing adverse impacts of the crisis. These have occurred since the second half of 2008. The article analyses the contributions to GDP and trends in future years. There are also described changes in the sector economic structure with focus on agriculture.
Diverging evolution of light pollution indicators: can the Globe at Night and VIIRS-DNB measurements be reconciled?

description: The radiance of nighttime artificial lights measured by the VIIRS-DNB instrument on board the satellite Suomi-NPP increases at an average rate ~2.2 %/yr worldwide, whereas the artificial radiance of the night sky deduced from the Globe at Night (GAN) unaided-eye observations of the number of visible stars is reported to increase at an average rate ~9.6 %/yr. The difference between these two estimates is remarkable. This raises the question of whether the diverging temporal evolution of these indicators could be due to changes in the spectral composition of outdoor artificial light, consequence of the current process of replacement of lighting technologies. This paper presents a model for evaluating the temporal rate of change of different light pollution indicators and applies it to the VIIRS-DNB vs GAN issue, based on available data. The results show that the reported difference could be explained by spectral changes alone, if the visual GAN observations are made with scotopic or mesopic adaptation at definite times under some particular transition conditions. In case of photopic adapted observers, however, reconciling these two measurement sets requires the existence of GAN-specific light sources that affect the Globe at Night observations but do not show up in the VIIRS-DNB data. The lumen emissions of these GAN-specific sources for photopic observers should increase at a rate larger than 9%/yr worldwide.

description: The paper is focused on the modeling of a partial equilibrium on the beef market in the Czech Republic. The goal of the paper is a construction and a quantification of a partial equilibrium model of mentioned trade, used for simulation purpose and enabling delimitation of main determinants of beef supply and demand. Data was gained from standard statistical reports of the Ministry of Agriculture and from Statistics of Households Accounts from the year 1995 – 2009. Proposed model respects three levels of beef chain – farmer, processer and consumer. Simultaneously, it respects trade flows on an open market. From the functional point of view, it respects nonlinearity of suppose relationships. The model was quantified by OLS with respects of recursive relationship between endogenous variables. The model is robust enough to be used for simulations. The paper resulted from contribution to an institutional research project MSM 6046070906.

Landslide Tsunamis in Lakes

description: Landslides plunging into lakes and reservoirs can result in extreme wave runup at shores. This phenomenon has claimed lives and caused damage to near-shore properties. Landslide tsunamis in lakes are different from typical earthquake tsunamis in the open ocean in that (i) the affected areas are usually within the near-field of the source, (ii) the highest runup occurs within the time period of the geophysical event, and (iii) the enclosed geometry of a lake does not let the tsunami energy escape. To address the problem of transient landslide tsunami runup and to predict the resulting inundation, we utilize a nonlinear model equation in the Lagrangian frame of reference. The motivation for using such a scheme lies in the fact that the runup on an inclined boundary is directly and readily computed in the Lagrangian framework without the need to resort to approximations. In this work, we investigate the inundation patterns due to landslide tsunamis in a lake. We show by numerical computations that Airy's approximation of an irrotational theory using Lagrangian coordinates can legitimately predict runup of large amplitude. We also demonstrate that in a lake of finite size the highest runup may be magnified by constructive interference between edge-waves that are trapped along the shore and multiple reflections of outgoing waves from opposite shores, and may occur somewhat later after the first inundation.

Finally, I give an example of how the method can also be useful for lattice calculations.

The rate of metastable vacuum decay in (2+1) dimensions
Creators: name: Voloshin, M. B.
Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The pre-exponential factor in the probability of decay of a metastable vacuum is calculated for a generic (2+1) dimensional model in the limit of small difference $ε$ of the energy density between the metastable and the stable vacua. It is shown that this factor is proportional to $ε^{-7/3}$ and that the power does not depend on details of the underlying field theory. The calculation is done by using the effective Lagrangian method for the relevant soft (Goldstone) degrees of freedom in the problem. Unlike in the (1+1) dimensional case, where the decay rate is completely determined by the parameters of the effective Lagrangian and is thus insensitive to the specific details of the underlying (microscopic) theory, in the considered here (2+1) dimensional case the pre-exponential factor is found up to a constant, which does depend on specifics of the underlying short-distance dynamics, but does not depend on the energy asymmetry parameter $ε$. Thus the functional dependence of the decay rate on $ε$ is universally determined in the considered limit of small $ε$.

description: This paper considers the stochastic production frontier approach to analyse the technical efficiency and its determinants of fish farms in Ghana using a cross-section data of 150 farms. It considers the explicit effects of family and hired labour on production by setting the log-value of the zero-observation of these two sources of labour to zero with dummy variables. Results demonstrate that expected elasticities of mean output with respect to all input variables are positive and significant. Findings also show that family and hired labour used for fish farming in Ghana may be equally productive. Fish farms in Ghana are revealed to be characterised by technology with increasing return to scale. The combined effects of operational and farm specific factors are found to influence efficiency. The study further reveals that inclusion of interaction between some exogenous variables in the inefficiency model is significant in explaining the variation in efficiency. Results also suggest that small pond operators are more efficient than farms with large ponds. Mean technical efficiency is estimated to be 78 percent.

description: The aim of this paper is to exploit grain price data to detect the warning signs of looming food crises in Mali, Burkina Faso and Niger. Firstly we identify which markets play a leading role at the national and regional level. The second step consists of identifying crisis periods and characterizing price movements during the period proceeding a crisis. This analysis leads to the identification of early warning indicators whose relevance is tested using panel data qualitative choice models. The results show that monitoring price movements on "leading markets" during crucial periods of the year can help in forecasting future crises.

description: We present constraints on the $f(R)$ gravity model using a sample of 1,005 galaxy clusters in the redshift range $0.25 - 1.78$ that have been selected through the thermal Sunyaev-Zel'dovich effect (tSZE) from South Pole Telescope (SPT) data and subjected to optical and near-infrared confirmation with the Multi-component Matched Filter (MCMF) algorithm. We employ weak gravitational lensing mass calibration from the Dark Energy Survey (DES) Year 3 data for 688 clusters at $z < 0.95$ and from the Hubble Space Telescope (HST) for 39 clusters with $0.6 < z < 1.7$. Our cluster sample is a powerful probe of $f(R)$ gravity, because this model predicts a scale-dependent enhancement in the growth of structure, which impacts the halo mass function (HMF) at cluster mass scales. To account for these modified gravity effects on the HMF, our analysis employs a semi-analytical approach calibrated with numerical simulations. Combining calibrated cluster counts with primary cosmic microwave background (CMB) temperature and polarization anisotropy measurements from the Planck2018 release, we derive robust constraints on the $f(R)$ parameter $f_{R0}$. Our results, $\log_{10} |f_{R0}| < -5.32$ at the 95 % credible level, are the tightest current constraints on $f(R)$ gravity from cosmological scales. This upper limit rules out $f(R)$-like deviations from general relativity that result in more than a $\sim$20 % enhancement of the cluster population on mass scales $M_\mathrm{200c}>3\times10^{14}M_\odot$.

Seat structural design choices and the effect on occupant injury potential in rear end collisions
Creators: name: Skipper, Christopher Scott
Publisher: name: University of British Columbia
Year: 2009

description: The seat is the most important safety device available to vehicle occupants during rear end collisions, and thus proper design and structural integrity of the seat under expected impact loading is essential. The objective of the current research work is to increase the understanding of design requirements for seat performance in relation to injury producing collisions, and to examine how various seat design parameters affect both structural integrity and occupant protection. A numerical model-based finite element parametric sensitivity study (conducted in LS-Dyna) was employed with the goal of assessing the effect of seat structural properties on occupant kinematics and injury response. A 2002 Pontiac Grand Am seat was utilized to create the base geometry for the finite element seat model used in the study. The parametric study utilized a 50th percentile male dummy, applied the CMVSS 202 standard crash pulse to selected structural variations of this seat, and then utilized the neck injury criterion (NIC), neck displacement criterion (NDC) and relative neck accelerations to assess the likelihood of injury. Seatback and recliner angle, and the degree of seatback twist are utilized to indicate seat performance. Based upon this work, there are significant structural components of the seat that contribute to injury mitigation. The recliner rotational stiffness and the head restraint stiffness are the most significant seat structural design choices, which can mitigate injury potential. Recliner stiffness results indicate that stiff recliners offer injury risk reduction. A stiff head restraint that absorbs little energy mitigates injury. The seatback frame can mitigate injury by absorbing energy through plastic deformation. The risk of occupant ejection is reduced through the use of seatmounted seatbelt retractors, although dual retractor systems mounted to the vehicle's b-pillar and seat base provide comparable ramping reduction. Energy correlations have been derived that offer a first step toward relating seat design to injury.

description: The definition of an action functional for the Jacobi sigma models, known for Jacobi brackets of functions, is generalized to \emph{Jacobi bundles}, i.e., Lie brackets on sections of (possibly nontrivial) line bundles, with the particular case of contact manifolds. Different approaches are proposed, but all of them share a common feature: the presence of a \emph{homogeneity structure} appearing as a principal action of the Lie group $\mathbb{R}^{\times}=\mathrm{GL}(1;\mathbb{R})$. Consequently, solutions of the equations of motions are morphisms of certain \emph{Jacobi algebroids}, i.e., principal $\mathbb{R}^{\times}$-bundles equipped additionally with a compatible Lie algebroid structure. Despite the different approaches we propose, there is a one-to-one correspondence between the space of solutions of the different models. The definition can be immediately extended to \emph{almost Poisson} and \emph{almost Jacobi brackets}, i.e., to brackets that do not satisfy the Jacobi identity. Our sigma models are geometric and fully covariant.

description: The paper approaches the problem of assessing the impacts of market and rural development policies oriented at stimulating the growth and spread of organic farming in Italy. From the methodological perspective, an innovative formulation of Pmp is presented and discussed; it is applied to a set of farms belonging to the FADN sample, specifically located in Emilia Romagna and Sicily. The Pmp model has the capacity to estimate the impact of policies on crops not yet present at the time the farm data was recorded. From the empirical standpoint, various sets of policies are simulated on cluster of farms both conventional and in course of conversion in organic production.

This study presents a comprehensive experimental study of the evolution of Poisson’s

ratio and tangent modulus of polymeric foams during rate dependant uniaxial

compression. In this study, polyurethane foams with densities of 195 kg/m3, 244 kg/m3,

and 405 kg/m3 obtained from PORON (XRD series) were examined under uniaxial

compression loading at strain rates ranging from 0.001 s−1 to 5000 s−1. All compression

experiments were coupled with a high-speed camera to enable Digital Image Correlation

to measure and visualize deformation strains. These measurements enable us to study

mechanical property evolution during compression and provide qualitative description

of damage and failure in these materials. A non-linear evolution of Poisson’s ratio is

observed in-situ in these materials. The compressive stress-strain response is predicted

through least square fitting using the Avalle model [1], and model coefficients are found

to follow a power-law to scale across strain rates. The stress-strain curves, mechanical

property evolution, and scaling coefficients are compared with microstructural parameters

of interest such as pore size and wall thickness to inform on damage mechanisms in the material.
Trotter error time scaling separation via commutant decomposition

description: Suppressing the Trotter error in dynamical quantum simulation typically requires running deeper circuits, posing a great challenge for noisy near-term quantum devices. Studies have shown that the empirical error is usually much smaller than the one suggested by existing bounds, implying the actual circuit cost required is much less than the ones based on those bounds. Here, we improve the estimate of the Trotter error over existing bounds, by introducing a general framework of commutant decomposition that separates disjoint error components that have fundamentally different scaling with time. In particular we identify two error components that each scale as $O(τ^pt)$ and $O(τ^p)$ for a $p$th-order product formula evolving to time $t$ using a fixed step size $τ$, it implies one would scale linearly with time $t$ and the other would be constant of $t$. We show that this formalism not only straightforwardly reproduces previous results but also provides a better error estimate for higher-order product formulas. We demonstrate the improvement both analytically and numerically. We also apply the analysis to observable error relating to the heating in Floquet dynamics and thermalization, which is of independent interest.
