description: We use tree-level perturbation theory to show how non-supersymmetric one-loop scattering amplitudes for a Higgs boson plus an arbitrary number of partons can be constructed, in the limit of a heavy top quark, from a generalization of the scalar graph approach of Cachazo, Svrcek and Witten. The Higgs boson couples to gluons through a top quark loop which generates, for large top mass, a dimension-5 operator H tr G^2. This effective interaction leads to amplitudes which cannot be described by the standard MHV rules; for example, amplitudes where all of the gluons have positive helicity. We split the effective interaction into the sum of two terms, one holomorphic (selfdual) and one anti-holomorphic (anti-selfdual). The holomorphic interactions give a new set of MHV vertices -- identical in form to those of pure gauge theory, except for momentum conservation -- that can be combined with pure gauge theory MHV vertices to produce a tower of amplitudes with more than two negative helicities. Similarly, the anti-holomorphic interactions give anti-MHV vertices that can be combined with pure gauge theory anti-MHV vertices to produce a tower of amplitudes with more than two positive helicities. A Higgs boson amplitude is the sum of one MHV-tower amplitude and one anti-MHV-tower amplitude. We present all MHV-tower amplitudes with up to four negative-helicity gluons and any number of positive-helicity gluons (NNMHV). These rules reproduce all of the available analytic formulae for Higgs + n-gluon scattering (n<=5) at tree level, in some cases yielding considerably shorter expressions.

description: The modern concept of rural development implies the use of agricultural resources, primarily agricultural land, for other (non-agricultural) activities besides its agricultural purpose. The integral aim of this concept of rural development is the maximization of economic results, besides the sustainable development of rural areas, environmental protection and the production of strategic (staple) agricultural products. The objective of this paper is to define the general, theoretical, quantitative model for the determination of the size and quality of agricultural land which, considering the above-mentioned demands (criteria) is optimal for the utilization in agricultural production in certain regions. The remaining agricultural land would be available for the non-agricultural purposes. The economic optimal model for the selection of agricultural land in the traditional agriculture is the model of linear programming. The criteria of the land selection for traditional agriculture are the economic effectiveness (measured by net income or by gross national product) and the economic efficiency (measured by the production economy). The maximum economic effectiveness is determined by the standard method of linear programming and the maximum economy by the method of broken linear programming. The solution of compromise can be determined by multi-criteria programming, based on the minimum differences. The limitation groups in the mentioned variations of the model are: limitations of production quotas of agricultural products, minimum quantities of staple agricultural products, limitations of processing plants in a region (minimum and maximum), limitation of crop rotation, limitations of the needs in animal husbandry for bulky forage and limitations of agricultural land according to various types of utilization. By quantitative defining of the structure and size of agricultural land for traditional agriculture, “the surplus” and structure of agricultural land available for non-agricultural purposes is automatically determined.
Cognitive and affective features of a personality risk factor for depression and alcoholism

description: Despite the well-established relationship between depression and alcoholism, the psychological processes that link these two disorders are not well understood. The focus of the current study is on a personality construct called introversion/hopelessness (I/H), which recent research has identified as a potential motivational link between depression and alcoholism (Conrod, Pihl, Stewart, & Dongier, 2000). In this study, high introverted-hopeless (HH) and low introverted-hopeless (LH) individuals were compared on various aspects of cognitive and emotional functioning that were hypothesized to be susceptible to the effects of alcohol. Cognitive measures included the dysfunctional attitudes scale, memory bias for negative selfreferent information as measured by an incidental recall task, and attentional orienting as measured by a cued reaction time task. Emotional reactivity was assessed using a procedure designed to induce transient negative and positive mood states. Cognitive reactivity to induced mood was also assessed. Results revealed that the HH group, compared to the LH group, had stronger baseline dysfunctional attitudes, a more negative self-view, and sadder affect. However, these differences were negligible when depression was covaried out. The HH group also showed preferential recall of negative self-referent information. In exploratory analyses, baseline mood and response times on the attentional orienting task were found to be highly correlated in the HH group, but not the LH group. Contrary to expectations, HH individuals were less reactive to the negative mood induction both at an affective and cognitive level. The observed pattern of findings suggests that avoidance of negatively charged emotional states and a negatively biased cognitive style that is unresponsive to changes in mood are characteristic features of introversion-hopelessness.

description: In the digital age, the television landscape is profoundly expanded and dispersed across multiple media, introducing new paradigms of (post-)televisuality shaped by its constant digital transformation. Television content is distributed across digital platforms that fundamentally change its consumption practices. Through its fragmentation and digitization, television is breaking down into snippets—short, engaging pieces of media—that provide a dynamic, customizable, and “snackable” viewing experience, so that it is supposedly easy to digest. As a result, not only is there a shift in how content is viewed, but there is also a shift in how content is produced. Social media platforms and their algorithms have emerged as central to this transformation, facilitating the dissemination and discovery of television content in unprecedented ways. Platforms like Instagram and TikTok are not just venues for discussion and sharing but are also directly influencing the digital transformation of television. While specific essential characteristics define television (such as its seriality, scheduling, or formats), the digital transformation emerging from the internet is disrupting the medium and requiring (or even demanding) participatory modifications based on experimenting with different forms of media so that television gets expanded, explored, manipulated, and played with by consuming snackable content bit by bit. The concept of dis/array proposed in this article encapsulates the dual forces of fragmentation and reorganization. Disarray, characterized by the oversupply of content, reflects the challenges audiences face in navigating a dispersed landscape. Conversely, array represents the efforts by platforms and users to restore order through algorithms, categorization, and interactive engagement. By analyzing current trends and audience behaviors, this article reveals how streaming, social media, and snippets contribute to the transformation of television.

description: The paper is devoted to studying controllability properties for 3D Navier-Stokes equations in a bounded domain. We establish a sufficient condition under which the problem in question is exactly controllable in any finite-dimensional projection. Our sufficient condition is verified for any torus in $R^3$. The proofs are based on a development of a general approach introduced by Agrachev and Sarychev in the 2D case. As a simple consequence of the result on controllability, we show that the Cauchy problem for the 3D Navier-Stokes system has a unique strong solution for any initial function and a large class of external forces.

description: The multi-messenger discovery of gravitational waves (GWs) and light from the binary neutron star (NS) merger GW170817, associated with Gamma-Ray Burst (GRB) 170817A and kilonova AT2017gfo, has marked the start of a new era in astrophysics. GW170817 has confirmed that binary NS mergers are progenitors of at least some short GRBs. The peculiar properties of the GRB 170817A radio afterglow, characterized by a delayed onset related to the off-axis geometry, have also demonstrated how some nearby short GRBs may not be identified as such with standard short-timescale electromagnetic follow-up observations. Building upon this new information, we performed late-time radio observations of a sample of four short GRBs with unknown redshift and no previously detected afterglow in the \textit{Swift}/BAT sample in order to identify nearby ($d_L\lesssim 200$ Mpc) off-axis GRB candidates via their potential late-time radio signatures. We find a previously uncatalogued radio source within the error region of GRB 130626 with a $3-6$ GHz flux density consistent with a NS radio flare at a distance of $\sim 100$ Mpc. However, an origin related to a persistent radio source unrelated to the GRB cannot be excluded given the high chance of false positives in error regions as large as those considered here. Further radio follow-up observations are needed to better understand the origin of this source.

description: This work addresses the problem of point cloud registration using deep neural networks. We propose an approach to predict the alignment between two point clouds with overlapping data content, but displaced origins. Such point clouds originate, for example, from consecutive measurements of a LiDAR mounted on a moving platform. The main difficulty in deep registration of raw point clouds is the fusion of template and source point cloud. Our proposed architecture applies flow embedding to tackle this problem, which generates features that describe the motion of each template point. These features are then used to predict the alignment in an end-to-end fashion without extracting explicit point correspondences between both input clouds. We rely on the KITTI odometry and ModelNet40 datasets for evaluating our method on various point distributions. Our approach achieves state-of-the-art accuracy and the lowest run-time of the compared methods.

description: In this work we construct families of anisotropic neutron stars for an equation of state compatible with the constraints of the gravitational-wave event GW170817 and for four anisotropy ansatze. Such stars are subjected to a radial perturbation in order to study their stability against radial oscillations and we develop a dynamical model to describe the non-adiabatic gravitational collapse of the unstable anisotropic configurations whose ultimate fate is the formation of a black hole. We find that the standard criterion for radial stability $dM/dρ_c >0$ is not always compatible with the calculation of the oscillation frequencies for some anisotropy ansatze, and each anisotropy parameter is constrained taking into account the recent restriction of maximum mass of neutron stars. We further generalize the TOV equations within a non-adiabatic context and we investigate the dynamical behaviour of the equation of state, heat flux, anisotropy factor and mass function as an unstable anisotropic star collapses. After obtaining the evolution equations we recover, as a static limit, the background equations.

description: We present the analysis of the X-ray Multi-Mirror Mission (XMM-Newton) European Photon Imaging Camera (EPIC) data of the Galactic supernova remnant (SNR) CTB 109 (G109.1-1.0). CTB 109 is associated with the anomalous X-ray pulsar (AXP) 1E 2259+586 and has an unusual semi-circular morphology in both the X-ray and the radio, and an extended X-ray bright interior region known as the `Lobe'. The deep EPIC mosaic image of the remnant shows no emission towards the west where a giant molecular cloud complex is located. No morphological connection between the Lobe and the AXP is found. We find remarkably little spectral variation across the remnant given the large intensity variations. All spectra of the shell and the Lobe are well fitted by a single-temperature non-equilibrium ionization model for a collisional plasma with solar abundances (kT = 0.5 - 0.7 keV, tau = n_e t = 1 - 4 x 10^11 s cm^-3, N_H = 5 - 7 x 10^21 cm^-2). There is no indication of nonthermal emission in the Lobe or the shell. We conclude that the Lobe originated from an interaction of the SNR shock wave with an interstellar cloud. Applying the Sedov solution for the undisturbed eastern part of the SNR, and assuming full equilibration between the electrons and ions behind the shock front, the SNR shock velocity is derived as v_s = 720 +/- 60 km s^-1, the remnant age as t = (8.8 +/- 0.9) x 10^3 d_3 yr, the initial energy as E_0 = (7.4 +/- 2.9) x 10^50 d_3^2.5 ergs, and the pre-shock density of the nuclei in the ambient medium as n_0 = (0.16 +/- 0.02) d_3^-0.5 cm^-3, at an assumed distance of D = 3.0 d_3 kpc. Assuming CTB 109 and 1E 2259+586 are associated, these values constrain the age and the environment of the progenitor of the SNR and the pulsar.

description: What does rural Europe look like in 2030? Is agriculture still the main land user? In recent years, studies such as ESPON, Eururalis, SCENAR2020, SENSOR, SEAMLESS and PRELUDE have tried to address these questions. These studies resulted in a number of alternative futures of rural areas in the EU. In this paper a comparative analysis of these scenario studies is made in order to explore differences and similarities in the scenarios and alternative futures of rural areas in the EU. For this purpose, we designed a scheme for assessing the properties of the various scenarios and a scheme for a systematic description of the rural futures according to the scenarios. It appears that most scenario studies use a baseline scenario and a set of alternative scenarios with different degrees of policy regulation. Agriculture will continue to be a main land user in 2030, although some land abandonment will take place.

description: We study the effect of resetting on diffusion in a logarithmic potential. In this model, a particle diffusing in a potential $U(x) = U_0\log|x|$ is reset, i.e., taken back to its initial position, with a constant rate $r$. We show that this analytically tractable model system exhibits a series of phase transitions as a function of a single parameter, $βU_0$, the ratio of the strength of the potential to the thermal energy. For $βU_0-1$ the potential is either weakly repulsive or attractive and the diffusing particle eventually reaches the origin. In this case, we provide a closed form expression for the subsequent first-passage time distribution and show that a resetting transition occurs at $βU_0=5$. Namely, we find that resetting can expedite arrival to the origin when $-15$. The results presented herein generalize results for simple diffusion with resetting -- a widely applicable model that is obtained from ours by setting $U_0=0$. Extending to general potential strengths, our work opens the door to theoretical and experimental investigation of a plethora of problems that bring together resetting and diffusion in logarithmic potential.

description: Input of biological data: To continue to develop the in vivo (animal and human) data input form, to conduct trial evaluations of the form, to finalise it, and to use it to capture data on studies focusing on animal and human interventions with plant-based bioactives. Prior to the BEG meeting in April, some development work had been carried out on the in vivo (animal) data evaluation form, and a trial was run in early April 2006. Each evaluator received the same two in vivo (animal) papers to evaluate using the initial draft of the input form. The outcome of this trial was discussed at the BEG meeting in Cork in April 2006. Similarly with the in vitro form, changes were recommended at the meeting and several adjustments to the forms were made before any further evaluations were carried out. A sample form including updated help texts was developed to act as a guide for evaluators to finalise the in vivo input form. Evaluators have been using this in vivo (animal) input form since July 2006, and to date 65 in vivo papers have been critically evaluated and incorporated into the database, representing in excess of 150 input forms.

description: This paper examines the secrecy performance of millimeter-wave (mm-Wave) communications with imperfect hardware and uncertain eavesdropper location. We consider a multiple-antenna source communicating with a single-antenna destination using masked beamforming to transmit the information signals with artificial noise (AN) in the presence of a passive eavesdropper (Eve). For this system, we derive new expressions for the secrecy outage probability (SOP) and secrecy throughput with mm-Wave multipath propagation under slow-fading channel conditions and hardware imperfections. Based on this, optimal power allocation (OPA) solutions are derived for the information and AN signals aimed at minimizing the SOP and maximizing the secrecy throughput. Our results reveal that it is non-trivial to achieve an OPA solution for the general scenario of imperfect hardware. We also highlight that our proposed masked beamforming with OPA scheme significantly enhances the secrecy throughput compared with the benchmark schemes of maximal-ratio transmission and equal power allocation.

description: We analyze the thermodynamic properties of the spin-S two-dimensional quantum Heisenberg antiferromagnet on a square lattice with nearest and next-nearest neighbor couplings in the Neel phase (J_2/J_1<0.4) employing the quantum hierarchical reference theory (QHRT), a non-perturbative implementation of the renormalization group method to quantum systems. We investigate the staggered susceptibility, the structure factors and the correlation length at finite temperature and for different values of the frustration ratio. From the finite temperature results, we also extrapolate ground state properties, such as spin stiffness and spontaneous staggered magnetization, providing an estimate of the extent of quantum corrections. The behavior of these quantities as a function of frustration may provide some hint on the breakdown of the Neel phase at zero temperature for larger values of J_2.

In the first case, we are able to resolve the QSO and find that it is hosted by an elliptical of absolute magnitude M(K) = -27.6. For the other two objects, no extended emission has been unambiguously detected. This result, though restricted to a single object, extends up to z ~2.5 the finding that cosmic evolution of radio-loud QSO hosts follows the trend expected for luminous and massive spheroids undergoing passive evolution. For Q 0045-3337, our high resolution images show that it is located 1.2 arcsec from a K = 17.5 foreground disc galaxy, which may act as a gravitational lens, since the QSO most probably lies within the galaxy Einstein radius.

description: Agriculture and agricultural extension service are facing numerous problems in present times when good solutions are not easy to find. Providing of agricultural extension service is important foreign-political instrument of a state which has stimulates the development of agricultural production. Agricultural extension service must provide effective link between holdings-producers, agricultural research and other sources of information. Agricultural extension agents must be aware of psycho-social and social aspects of group action and individual counselling. Therefore, one of priorities in agricultural development of our country is rising of the level of extension operation and establishment of extension service based on modern principles. This is the reason why in this paper, some of the traits of the genesis of extension services were indicated, as well as types of extension services and models of the organization, financing and human resources at disposal and structuring of these resources according to main characteristics, for the purpose of modernization and agricultural and rural development.

description: During the last years Italy, a country characterized by a long history of emigration, has seen a quickly growth of the phenomenon of immigration. Our Nation seems to be a “docking point” for new and substantial flow of immigrants mainly from Eastern Europe looking for new work opportunities. The profile of these people is usually characterized by high level of education as well as flexibility and adaptability. For the national economy in general, and for the agricultural sector in particular, this new migration flows represent an effective answer to the aversion for the agricultural job expressed by many potential autochthon workers. Which are the characteristics of extra-community agricultural labour? Which are the characteristics of migration flows linked to the agricultural labour in three provinces of one of the main agricultural regions in Italy? Based on National Institute of Welfare information’s (INPS), the research underlines the diversification of this phenomenon among Italian regions as well as its dynamism. In Italy, during the last five years, the proportions of foreign agricultural workers increased up to 50%, and peaked in four Italian regions: Friuli Venezia Giulia, Campania, Piemonte and Emilia-Romagna. In Emilia-Romagna, in particular, immigrants represent almost a quarter of total agricultural workers and most of them aged less than forty years. The analysis of information about labour market in the agricultural sector in some Emilia-Romagna provinces shows that immigrants are concentrated in few farms. Farmer prefers to engage homogeneous ethnic groups to assure cultural affinity among the employees. In the local agricultural labour market the immigrants coming from Eastern Europe, in particular from Poland and Romania, are aged between 22 and 36 years, are unemployed in their country, they have a driving license and a good knowledge of Italian and English language.

description: This document constitutes Deliverable 2.1 of the H2020-MSCA-IF-2020 Destiny’s project (Grant Agreement No 101024372). Destiny is a project dedicated to advance the state-of-the-art of WEC control technology by providing a novel and reliable nonlinear optimal control framework, maximising energy absorption for a wide range of ocean conditions for single and multiple devices, exhibiting real-time capabilities and globally optimal performance. The final aim is to provide all stakeholders in the wave energy field with a fundamental tool to facilitate reaching economic viability of wave energy technology.

 In particular, this document constitutes a report of the work done throughout work package 1 (WP1), on the extension of the class of nonlinearities within moment-based optimal control for wave energy systems, and its corresponding synergy with the remainder of the project. Two fundamental steps have been taken to achieve such an objective, including: 1) incorporation of input-dependent nonlinear effects (both hydrodynamic- and control-related), and 2) derivation of global optimality conditions for the extended nonlinear control framework, including the development of support tools to guarantee and assess such conditions in practical applications.

description: We have found a remarkable increase (up to 60 %) of the dielectric constant with the onset of magnetic order at 42 K in the metastable orthorhombic structures of YMnO3 and HoMnO3 that proves the existence of a strong magneto-dielectric coupling in the compounds. Magnetic, dielectric, and thermodynamic properties show distinct anomalies at the onset of the incommensurate magnetic order and thermal hysteresis effects are observed around the lock-in transition temperature at which the incommensurate magnetic order locks into a temperature independent wave vector. The orders of Mn3+ spins and Ho3+ moments both contribute to the magneto-dielectric coupling. A large magneto-dielectric effect was observed in HoMnO3 at low temperature where the dielectric constant can be tuned by an external magnetic field resulting in a decrease of up to 8 % at 7 Tesla. By comparing data for YMnO3 and HoMnO3 the contributions to the coupling between the dielectric response and Mn and Ho magnetic orders are separated.

Rheological effects on ultra-fine grinding in stirred mills
Creators: name: Yue, Jian
Publisher: name: University of British Columbia
Year: 2009

description: A pilot scale study was conducted on ultra-fine grinding in a horizontal stirred mill. The main objectives were to investigate grinding kinetics, the influences of rheology and effects of bead size on performance criteria. The main criteria were breakage rate, particle size reduction, product size distribution and power consumption. The results confirm the "first-order" breakage rates in stirred mills. The product size distributions are best represented by the Rosin-Rammler equation. A method of determining breakage rates versus particle size is demonstrated which shows that the 10% top size fraction is most appropriate for the determination of specific breakage rates. The slurries ground exhibit Newtonian to pseudoplastic to yield pseudoplastic behavior over the range of conditions studied, corresponding to coarse low percentage solids to fine high percentage solids. The flow curves of grinding products were modeled using the Casson equation. It was shown that yield stress is the dominant rheological parameter which influences the grinding performance. A Low yield stress favors high breakage rates, narrow size distributions, and increased production of -10 μm fines. The bead sizes and its composition play a very important role in stirred mills. There exists an optimum ratio of bead size to feed size with respect to breakage rate, size reduction ratio and size distribution. The ratio was confirmed to be about 20/1. The existence of fine beads in grinding media has negative effects on grinding performance.

description: We report the transmission over a wide frequency range (far infrared - visible) of pristine and hole-doped, free-standing carbon nanotube films at temperatures between 50 K and 300 K. Optical constants are estimated by Kramers-Kronig analysis of transmittance. We see evidence in the far infrared for a gap below 10 meV. Hole doping causes a shift of spectral weight from the first interband transition into the far infrared. Temperature dependence in both the doped and undoped samples is restricted to the far-infrared region.

description: In the paper, the authors analyse problems in the extension work and farmers’ needs on the basis of the empirical sociological survey that comprised attitudes of all the agricultural extension workers in Serbia. The survey has been conducted by the authors during 2008 in all of the extension offices in Serbia using the semi-structured questionnaire. The analysis reveals the regional specifics of the farmers’ needs and the problems that the advisors face in daily work, as well. According to the survey results there are three types of problems that are mutually connected: 1. general crisis of the agricultural sector, 2. problems regarding characteristics of farm holdings and farmers population in Serbia and 3. problems that are related to extension organization. Farmers’ needs analysis points to four dominant needs of farmers in Serbia: 1. farm management, 2. help in establishment of farmers’ cooperatives, 3. plant protection and 4. information and advice regarding the agricultural policy.

description: We find giant graviton solutions in Frolov's three parameter generalization of the Lunin-Maldacena background. The background we study has $\tildeγ_1=0$ and $\tildeγ_2=\tildeγ_3=\tildeγ$. This class of backgrounds provide a non-superymmetric example of the gauge theory/gravity correspondence that can be tested quantitatively, as recently shown by Frolov, Roiban and Tseytlin. The giant graviton solutions we find have a greater energy than the point gravitons, making them unstable states. Despite this, we find striking quantitative agreement between the gauge theory and gravity descriptions of open strings attached to the giant.

WEATHER RISK, CROP MIX, AND WEALTH IN THE SEMI-ARID TROPICS

Subjects: Crop Production/Industries

description: This paper estimates the impact of risk aversion on the farm household's choice of crop mix using the ICRISAT panel. To the extent that production risk is uninsured and households are risk averse, the choice of crop mix will deviate from the expected profit maximizing choice. The paper finds that farmer choices of crop mix are affected by weather risk in two of the ICRISAT villages considered here. Since poorer households are less able to smooth consumption ex post, their ex ante choices are further from the expected profit maximizing crop mix. Empirical results support the model of crop choice. Moreover, poorer households allocate land to a mix of crops with lower risk (and lower average profits), as predicted by the model. This likely contributes to the rise in inequality in the villages over the study period.

INVERSE PRODUCTIVITY: LAND QUALITY, LABOR MARKETS, AND MEASUREMENT ERROR

Productivity Analysis

description: This paper verifies the existence of the inverse productivity relationship in the ICRISAT data and examines the role that land quality and imperfect markets play in generating it. The empirical approach is straightforward, and allows for more direct tests of the land quality or imperfect labor market hypotheses than previous studies. The ICRISAT information on plot-level soil quality and measures of labor and land market failures are used to see if either land quality or market failure can fully account for the inverse relationship. Differences in land quality measured by soil type, irrigation, and the value of farm land largely explain the IP relationship in the random effects profit regression, but not in labor demand regressions. Controlling for labor and land market failures and differences in soil quality eliminates the IP relationship for male labor, but not female labor in the random effects estimates. The inverse relationship is much stronger in fixed-effects than random-effects estimates, suggesting that the farm size variable may be subject to measurement error. Instrumental variables estimation is used to correct possible measurement error in farm size, wiping out the IP relationship in the fixed effects estimates of both profits and female labor demand.
