description: The influence of the rotation on the total masses and radii of the neutron stars are calculated by the Hartle's slow rotation formalism, while the equation of state is considered in a relativistic $σ-ω$ model. Comparing with the observation, the calculating result shows that the double neutron star binaries are more like hyperon stars and the neutron stars of X-ray binaries are more like traditional neutron stars. As the changes of the mass and radius to a real neutron star caused by the rotation are very small comparing with the total mass and radius, one can see that Hartle's approximate method is rational to deal with the rotating neutron stars. If three property values: mass, radius and period are observed to the same neutron star, then the EOS of this neutron star could be decided entirely.

description: This article emphasizes the strategic and operations aspects of managing a farm. In this article, farm management performance is analyzed based on yearly Illinois Farm Business Farm Management (FBFM) panel data across 9,831 farms from 1996 through 2014. The alpha scores (or skill estimates) for farm managers are analyzed to determine if most profitable farmers possess specific skills or knowledge against adverse events in a volatile environment. Farms are evaluated under different scenarios of management skill portfolios. Fundamental farm management basics are discussed in this study, including budgeting, production planning, financial analysis, financial management, investment analysis, and control management. We find substantial difference of farm management styles and performance efficiency in management skill portfolios. We also find evidence of most skilled farm managers are more efficient on both revenue side and costs side. The approaches used in this study also allow comparison among farms of different sizes and types. The activities of top farms can be replicated by poorer performers and the study provide a unique way for comparing the farm management styles and ability of most skilled farm managers to that of less skilled ones. The innovative method is framed by comparing business strategies and performance styles in the following aspects: production and operations planning, land management and control, and production costs evaluation. Farm managers will want to consult it as well to improve the effectiveness, objectivity, and success of their decisions.

description: The Information Entropy Spacetime Unification Hypothesis (IESUH) proposes a new framework to unify spacetime, information theory, thermodynamics, and fundamental forces. It suggests that entropy is intrinsically tied to spacetime, shaping its curvature and governing the propagation of forces like gravity and electromagnetism. A key concept, entropy flow velocity, describes how entropy changes over time, potentially influencing the speed of light, force interactions, and time dilation. IESUH posits that spacetime emerges from the dynamic flow of information, functioning as both a storage medium and a computational process. The laws of physics may arise from deeper computational principles that dictate how information is encoded, transmitted, and processed. In this view, the speed of light results from spacetime constraints on information flow, rather than being a fundamental limit. The theory also introduces microscopic entropy carriers, akin to quantum particles, which facilitate information transfer at fundamental scales. Higher dimensions may play a role in this framework, explaining quantum entanglement as information exchange beyond classical speed constraints. Gravitational waves are, similarly, seen as signals of information exchange between cosmic systems. IESUH implies that the dynamics of entropy directly influences time, and increasing entropy accelerates the observer's experience of it. This could allow entropy-driven time manipulation or quantum tunnels enabling "jumps" into the future, though travel to the past remains impossible because of thermodynamic irreversibility. Ultimately, IESUH redefines spacetime as an emergent, self-organizing computational process, offering new insights into quantum gravity, black holes, and the fundamental nature of reality.

description: This research investigates the unconditional and conditional volatility in wheat, flour, and high and low quality rice price returns in Afghanistan. It also considers volatility spillover from the exporting countries and global markets to the domestic markets. The ARCH LM test and GARCH (1,1) model with exogenous variables are, inter alia, employed in the analysis. The results suggest the existence of volatility clustering and persistence in all of the price return series examined, which indicates a prolonged period of uncertainty in the domestic markets after a shock that can harm both consumers and producers. Evidence of volatility spillover from exporting countries to domestic markets is also observed such that the domestic markets may be relatively less vulnerable to import wheat and flour from Kazakhstan, and rice from Pakistan. As price levels, both conditional and unconditional price volatility in the price returns have declined after January 2011 such that the level of decrease is larger for wheat and flour price returns while it is meager for the returns of high and low quality rice prices. Given the country’s context, the findings of this research imply that extreme and unpredictable changes in the staple food prices may not only deteriorate the welfare of poor households but their persistence also create uncertainty for all of the market participants.

description: No abstracts are to be cited without prior reference to the author.Plaice in Kattegat and Skagerrak have traditionally been considered as one stock unit. However the collected information on biology and fishery in areas between the North and the Baltic Seas suggest for changes in assessment units as well as in management areas. Plaice in Skagerrak (Division 20) is now considered to be closely associated with plaice in the North Sea and is proposed to be included in the North Sea plaice stock assessment, although it is recognized that local populations are present in the area. Therefore, specific management of the Skagerrak plaice is suggested
Temporal Movements as Agency in an Arctic Landscape : Vuntut Gwitchin traditional territory

description: The praxis of people who work with land and physical spaces that can be inhabited should carry a growing weight in an age that requires sustainable design that is responsive to place and inclusive to values of reconciliation. I cannot and would not want to tell anyone what reconciliation is, but I believe it is a continuous working process that involves cross-cultural understanding, perspective and sensitivity. This involves comprehensive, meaningful and long-term engagement with people indigenous to the land. Being a white settler and landscape architecture candidate I wanted to become more cognizant of implications of how I consider working with the land. A large reason that I took this project on was to learn about landscape from people whom have deep ancestral connections to the land, of which cannot be replicated. Research leading up to this project underwent three ethics reviews, one that was from the Heritage Committee in Old Crow. I chose this location due to having spend a portion of my early adult life working a community engagement role in the Yukon and wanted to understand what landscape architecture could be in a remote, arctic community. Members of the Vuntut Gwitchin First Nation warmly welcomed me into their community and homes on separate occasions in the summer and winter season leading up to the end of this process. I hope that this project is a starting point for me to continue doing work in the north.

description: Researchers believe that greenhouse gas emissions (GHG) from livestock are an emerging problem. Beef cattle is one of the most emission-intensive sectors, which is responsible for 54% of total GHGs from livestock. This study has two purposes. First, we quantify the environmental loading of U.S. beef sector by calculating emission levels over the period 1970-2014. Following Intergovernmental Panel on Climate Change (IPCC) guideline, we identify three sources of emissions, including enteric fermentation, manure management, and manure left on pastures. Second, we provide an understanding of consumption-environmental connection related to the beef industry. We used Tire 1 method calculations in this study. This method will provide the basic information for establishing policies to mitigate climate change. We encourage to use Tire 2 method in future studies. It is also recommended to see the impact of changing geographical locations of cattle farm to the regions that have lower emission factors in future studies. It t is concluded that providing information to the public regarding livestock and climate change relationship would be beneficial. Media attention is needed to convey this message to the public that eating more meat is environmentally detrimental, and we need to change our diet to confine GHG emissions. This knowledge might help develop schemes to avoid the catastrophic climate change consequences in the future.

description: Following up the agricultural policy in Morocco and enforcing it, the new strategy Green Morocco Plan (GMP) launched in 2008 also stressed on the cereals’ supply. Meantime, despite their significant nutritional role, little attention has been paid to the demand side. This paper intends to perform an econometric analysis of the demand of five main cereals -Common wheat, Durum wheat, Barley, Corn and Rice- using a linear version of the flexible Almost Ideal Demand System (LA/AIDS model). A Seemingly Unrelated Regression (SUR) approach has been applied to the demand system equations with annual data covering the period from 1980 to 2015. At the overall, regular econometric restrictions (stability, structural separability, validity, etc.) have been respected our results suggest that the relations of complementarity or substitution are not determining in the cereal bundle in Morocco. Also, the Moroccan consumer behavior is characterized by a strong sensibility towards common wheat price’s changes and by a difficult access for the durum wheat as it is considered as luxury good.

description: Assessing sustainability of agricultural farms is among the most topical issues for researchers, farmers, investors, administrators, politicians, interests groups and public at large. In academic publications, official documents and agricultural practices social, economic and environmental aspects (pillars) of sustainability are assessed, while critical “governance” functions of the farm ignored. Nevertheless, comparative governance efficiency often (pre)determines the overall sustainability of a farm despite its (high) productivity, social responsibility or eco-conservation. Most frameworks usually employ “universal” approach for “faceless” farms and “anonymous” environment despite that real socio-economic, institutional and natural conditions are critical for sustainability. Assessment systems are not hierarchical and lack systemic organization of sustainability components leading to arbitrary selection of indicators. Besides, they are too simplified (few indicators), unilateral (“pure” economic, ecological, etc.), or too complicated and impossible to use. In this presentation we suggest a holistic approach for assessing absolute and comparative sustainability of farms of different juridical type, size, product specialization, ecological and geographical location in Bulgaria. It encompass governance, economic, social, and environmental aspects which are analyzed by a hierarchical system of 12 principles, 21 criteria, 45 indicators and reference values. Study, including 190 typical holdings, has found out that the overall sustainability of Bulgarian farms is good, with superior levels for environmental and social sustainability, and inferior level for governance and economic sustainability. There are great variations in sustainability levels of farms of different type and location as well as in shares of holdings with unlike sustainability level. In conclusion, we make recommendations for improvement of sustainability research and managerial practices.

description: We present a unique discovery of three new detected systems showing two different phenomena together. These are 2+2 quadruple stellar systems showing two eclipsing binaries as the inner pairs. And besides that, these systems were also found to exhibit the precession of the inner orbits causing the inclination changes manifesting themselves through the eclipse depth variations. We are not aware of any similar known system on the sky nowadays, hence our discovery is really unique. In particular these systems are: CzeV4315 = HD 228777 (periods 6.7391 d and 0.91932 d, inclination change of pair B of about 1.4deg/yr); ASASSN-V J075203.23-323102.7 = GDS_J0752031-323102 (8.86916 d + 2.6817 d, inclination change of pair B of about 1.03deg/yr, now only ellipsoidal variations); ASASSN-V J105824.33-611347.6 = TIC 465899856 (2.3304 d + 13.0033 d, inclination change of pair B, now undetectable). These systems provide us unique insight into the quadruple-star dynamics, including the orbit-orbit interaction, Kozai-Lidov cycles, and testing the stellar formation theories of these higher order multiples.

description: The quasar HE 0047-1756, at z=1.67, is found to be split into two images 1.44" apart by an intervening galaxy acting as a gravitational lens. The flux ratio for the two components is roughly 3.5:1, depending slightly upon wavelength. The lensing galaxy is seen on images obtained at 800 nm and 2.1 μ; there is also a nearby faint object which may be responsible for some shear. The spectra of the two quasar images are nearly identical, but the emission line ratio between the two components scale differently from the continuum. Moreover, the fainter component has a bluer continuum slope than the brighter one. We argue that these small differences are probably due to microlensing. There are hints of an Einstein ring emanating from the brighter image toward the fainter one.

description: The present work describes the preparation of gold nanoparticles (AuNPs) functionalized with hydroxamic acid and the use of them in UV-visible spectroscopy detection of iron(III) ions. The prepared AuNPs were thoroughly characterized by using UV-visible spectroscopy, TEM, and 1H NMR techniques. The newly synthesized hydroxamic acid-AuNPs are brown in color due to the intense surface plasmon absorption band centered at 527 nm. In the presence of Fe(III), the surface plasmon absorption band is centered at 540 nm. However, the sensitivity of hydroxamic acid-AuNPs towards other metal ions such as Mg(II), Ca(II), Ag(I), Cu(II), Mn(II), Cr(II), Ni(II), Co(II),Fe(II), Hg(II), and Pb(II) can be negligible. This highly selective sensor allows a direct quantitative assay of Fe(III) with a UVvisible spectroscopy detection limited to 45.8 nM.

The link is purely dispersive and the nonlinear square-law detector (SLD) operates at the thermal noise limit. The achievable rates of geometrically shaped PAM constellations are substantially increased by taking the SLD into account as compared to a WF that ignores the SLD.

description: No abstracts are to be cited without prior reference to the author.Centuries of fisheries research demonstrate that marine species exhibit complex spatial structure. Yet, spatially-explicit population dynamics models have only begun to gain popularity in the last two decades. Ignoring the spatial complexities of sub-population structure can be detrimental to sustainable fisheries management and lead to loss of biocomplexity. Recently, spatially-explicit assessment models have been developed in an attempt to match the spatial scales of natural populations. These models can incorporate a variety of spatial population structures, but are limited by data constraints. We describe a generic spatially-explicit tag-integrated stock assessment framework and the advanced data requirements for successful implementation of these types of models. Application of tag-integrated assessments requires knowledge of the population structure, fine-scale data, and information on connectivity between population components often in the form of tagging data. Spatially-explicit, tag-integrated models also use more conventional assessment information, such as catch-at-age and indices of abundance. The increase in resolution and realistic biological characteristics of spatially-explicit models comes at the cost of data sample size and associated increases in uncertainty. However, the development of fine-scale population models is imperative to effectively assess and manage spatiallystructured marine populations.

This virus became pandemic in March 11, 2019 and spread worldwide. Due tothe absence of specific vaccine, non-pharmacological interventions like social distancing, using disinfectantsand wearable masks and gloves are essential till finding an absolute solution. But during this time, ArtificialIntelligence methods could aid the available methods to reduce the number of confirmed cases by forecastingthe future based on available data from people of a specific region. Fortunately, there are considerable numberof up to data datasets of COVID-19 which contain time-series data. Three best of these datasets are JohnHopkins University, WHO and European Centre for Disease Prevention and Control datasets which this paperis employed them for experiment. This paper uses Takagi Sugeno Kang Fuzzy Neural Networks forecastingsystem on mentioned datasets for duration between two waves which is around 3.5 months. Some of thevalidation metrices are Mean Absolute Percentage Error (MAPE), Explained Variance (EV), and Root MeanSquared Log Error (RMSLE). By forecasting the first wave data for the second wave, highly similar to secondwave data are forecasted by the proposed system which, makes this system robust and applicable for futurewaves.

description: Topologically protected qubits based on nanostructures hosting Majorana bound states (MBSs) hold great promise for fault-tolerant quantum computing. We study the transport properties of nanowire networks hosting MBSs with a focus on the effects of the charging energy and the overlap between neighboring MBSs in short mesoscopic samples. In particular, we investigate structures hosting four MBSs such as T-junctions and Majorana boxes. Using a master equation in the Markovian approximation, we discuss the leading transport processes mediated by the MBSs. Single-electron tunneling and processes involving creation and annihilation of Cooper pairs dominate in the sequential tunneling limit. In the cotunneling regime the charge in the MBSs network is fixed and transport is governed by transitions via virtual intermediate states. Our results show that four-terminal measurements in the T-junction and Majorana box geometries can be useful tools for the characterization of the properties of MBSs with finite overlaps and charging energy.

description: We present a survey of the early evolution of 12 Type IIn supernovae (SNe IIn) in the Ultra-Violet (UV) and visible light. We use this survey to constrain the geometry of the circumstellar material (CSM) surrounding SN IIn explosions, which may shed light on their progenitor diversity. In order to distinguish between aspherical and spherical circumstellar material (CSM), we estimate the blackbody radius temporal evolution of the SNe IIn of our sample, following the method introduced by Soumagnac et al. We find that higher luminosity objects tend to show evidence for aspherical CSM. Depending on whether this correlation is due to physical reasons or to some selection bias, we derive a lower limit between 35% and 66% on the fraction of SNe IIn showing evidence for aspherical CSM. This result suggests that asphericity of the CSM surrounding SNe IIn is common - consistent with data from resolved images of stars undergoing considerable mass loss. It should be taken into account for more realistic modelling of these events.

description: Entanglement or modular Hamiltonians play a crucial role in the investigation of correlations in quantum field theories. In particular, in 1+1 space-time dimensions, the spectra of entanglement Hamiltonians of conformal field theories (CFTs) for certain geometries are related to the spectra of the physical Hamiltonians of corresponding boundary CFTs. As a result, conformal invariance allows exact computation of the spectra of the entanglement Hamiltonians for these models. In this work, we perform this computation of the spectrum of the entanglement Hamiltonian for the free compactified boson CFT over a finite spatial interval. We compare the analytical results obtained for the continuum theory with numerical simulations of a lattice-regularized model for the CFT using density matrix renormalization group technique. To that end, we use a lattice regularization provided by superconducting quantum electronic circuits, built out of Josephson junctions and capacitors. Up to non-universal effects arising due to the lattice regularization, the numerical results are compatible with the predictions of the exact computations.

description: We discuss the propagation of spectral line and continuum radiation in a clumpy medium and give general expressions for the observed absorption or emission from a cloud population. We show that the affect of the medium clumpiness can usually be characterised by a single number multiplying the mean column opacity. Our result provides a simpler proof and generalisation of the result of Martin et al (1984). The formalism provides a simple way to understand the effects of clumping on molecular line profiles and ratios, for example how clumping effects the interpretation of 13CO(1-0) to 12CO(1-0) line ratios. It can also be used as a propagation operator in physical models of clumpy media where the incident radiation effects the spectral line emissivity. We are working to extend the formalism to the propagation of masers in a clumpy medium, but in this case there are special difficulties because formal expectation values are not characteristic of observations because they are biased by rare events.

subject: semi-arid region

description: The study assessed producers’ awareness and perceptions of territorial-based qualities and the economic potential of two potential origin-based geographical indications in two semi-arid counties in Kenya. Protection of the origin products as geographical indications is presented as an option for ecosystem approach in managing fragile semi-arid regions while providing producers economic incentives and social inclusion; key components of green growth. Factor analysis was conducted on Likert scale perception questions administered to producers of goats (Baringo) and mangoes (Makueni). The producers were aware of the uniqueness of their products and its geographical source. The resultant factors reveal the importance of public policies, institutions, market access and public sector actors as important to producers’ perception of the success of protecting their products as geographical indications. Clustering revealed producer heterogeneity in their perceptions of protecting their respective products as geographical indications. The constitution of the clusters was significantly different based on the number of years the producers had practiced farming in the region, their awareness of the uniqueness of their goats, income received from goat production and institutional factors. Enhanced collective action for both goats and mangoes in the semi-arid regions would ensure collective reputation in the product presented to the market. The producers’ perceptions emphasise geographical indications as a marketing tool rather than an environmental tool, agreeing with Principle 4 of the ecosystem approach on managing ecosystem in an economic context.

description: The standard gravity model is adapted to determine and quantify factors which influence EU wine exports to the United States. Using the trade intensity index to represent a country’s relative share of the U.S. wine market, independent variables are chosen to augment the standard gravity model and identify the effects of transaction costs and productivity on the competitiveness of EU wine exports. Variables considered in the model include factors which represent a country’s capacity to trade and those that represent their cost of trade. Factors that influence a country’s capacity to trade include gross domestic product and relative per capita wine productivity; factors which influence cost to trade include distance between countries, import tariffs, and dummy variables related to trade agreements and whether the country is landlocked. Each of these factors is analyzed to determine how it affects the trade intensity. The positive GDP coefficient indicates the existence of intra-industry trade and suggests that the protection of Designations of Origin and Geographical Indications will help maintain EU wine exports. This analysis provides information that will enable producers and policy makers to better evaluate potential trade agreements and other strategies that influence the competitiveness of European wine in the world market.

Single Molecule Nonlinearity in a Plasmonic Waveguide

description: Plasmonic waveguides offer the unique possibility to confine light far below the diffraction limit. Past room temperature experiments of single quantum emitters coupled to such waveguides have mainly focused on efficient channelling of the spontaneous emission into waveguide modes after a linear optical excitation. However, only the simultaneous interaction of the emitter with multiple plasmonic fields would lead to functionality in a plasmonic circuit. Here, we demonstrate the nonlinear optical interaction of a single molecule and propagating plasmons. An individual terrylene diimide (TDI) molecule is placed in the nanogap between two single-crystalline silver nanowires. A visible wavelength pump pulse and a red-shifted depletion pulse travel along the waveguide, leading to stimulated emission depletion (STED) in the observed fluorescence. The efficiency increases by up to a factor of 50 compared to far-field excitation. Our study thus demonstrates remote nonlinear four-wave mixing at a single molecule with propagating plasmons. It paves the way towards functional quantum plasmonic circuits and improved nonlinear single-molecule spectroscopy.
title: Preliminary spatially disaggregated stock assessment of northern hake, a widely distributed stock of the north-east Atlantic

description: No abstracts are to be cited without prior reference to the author.European hake (Merluccius merluccius) is widely distributed over the north-east Atlantic shelf, from Norway to Mauritania. Despite its large distribution (covering ICES Division IIIa, Subareas IV, VI and VII and Divisions VIIIa,b,d, from Norway to the Bay of Biscay) and a complex population structure, the so-called northern stock of hake is currently assessed as a single unit, using a spatially aggregated implementation of the Stock Synthesis assessment model. In this study, a preliminary spatially explicit implementation of Stock Synthesis is developed, which accounts for the distribution of the hake population during its life cycle (nurseries and spawning areas) and the distribution of the fleets (trawlers, gillnetters and long-liners) exploiting the stock at various life stages. By explicitly incorporating spatial structure, the model can make consistent use of survey indices that only cover part of the stock distribution area. The model is fitted to commercial fishing data (landings, discards and quarterly size composition) and survey indices corresponding to the geographical areas defined in the model. Parameter estimation is carried out using the maximum likelihood estimation approach. Little information is currently available on exchange rates between main distribution areas and population structuring, so several hypotheses are tested. Implications in terms of stock assessment and management are discussed.

description: Isatin complexed with Cu supported on 4-(aminomethyl) benzoic acid-functionalizedFe3O4 nanoparticles (Cu-IS-AMBA-MNPs) as a new catalyst was designed, prepared and characterized by appropriate analyses. The heterogeneous reusable catalyst was successfully used for the efficient and widespread syntheses of diarylethers and diarylamines via the Ullmann coupling reaction. This green catalyst was easily removed, reused several times with no significant loss of its activity, and provided a clean synthesis with excellent yield and reduced time.

description: Two major political problems that face every community are: (1) to determine how much money the local government should spend and, given that quantity as a budgetary constraint; (2) what percentage of the budget should be allocated to each category of publicly provided goods and services. A new type of survey instrument, the bidding game, can be used to address the second problem. Commnunity attitudes are revealed by allowing each respondent to spend play money to construct his, or her, preferred budget. The outcomes of these games are utilized to construct a median budget. A mathematical model of political equilibrium suggests that a median budget will win a two way election with any other budget. Preliminary, quasi-experimental results support· this hypothesis.

description: In the framework of the seesaw mechanism, and adopting a typical form for the Dirac neutrino mass matrix, we discuss the impact of minimal forms of the Majorana neutrino mass matrix. These matrices contain four or three texture zeros and only two parameters, a scale factor and a hierarchy parameter. Some forms are not compatible with large lepton mixing and are ruled out. Moreover, a normal mass hierarchy for neutrinos is predicted.
