description: The extended dry conditions in the Murray Darling Basin have resulted in unprecedented levels of reduced water availability for both irrigators and the environment. Concerns over environmental degradation and the health of the river Murray have prompted the Federal and State Governments to cooperate in a range of environmental water restoration programs, including environmental water purchases. These programs have been subjected to varying levels of criticism as to the environmental effectiveness and the economic merit in addressing the central problem of over allocation of a spatially distributed multiple use resource. This paper investigates the economic-environmental tradeoffs under the assumption of unrestricted trade in the Basin. Using a bio-economic model of the Murray Darling Basin we will investigate the opportunity costs of not allowing unrestricted trade, and then consider alternative Environmental Water Allocations (EWAs) to environmental Icon Sites. The model suggests that if unrestricted trade was implemented across the Basin, there would be potential for massive water savings compared to the current long term average cap, and benefits to trade in the order of $96 million. The model also suggests that, under unrestricted trade, the provision of large EWA’s will lead to large reductions in water use (40 percent), however the relative reduction in agricultural value will be much less (12 percent). This brings to question the current objective of the government buybacks as a transition to the Water Act 2009 Sustainable Diversions while allowing State enforced barriers to trade.

description: We consider the nonrelativistic four-boson system in two dimensions interacting via a short-range attractive potential. For a weakly attractive potential with one shallow two-body bound state with binding energy B_2, the binding energies B_N of shallow N-body bound states are universal and thus do not depend on the details of the interaction potential. We compute the four-body binding energies in an effective quantum mechanics approach. There are exactly two bound states: the ground state with B_4^(0)=197.3(1)B_2 and one excited state with B_4^(1)=25.5(1)B_2. We compare our results to recent predictions for N-body bound states with large N>>1.

description: In this paper we study general properties of noncommutative field theories obtained from the Seiberg-Witten limit of string theories in the presence of an external B-field. We analyze the extension of the Wightman axioms to this context and explore their consequences, in particular we present a proof of the CPT theorem for theories with space-space noncommutativity. We analyze as well questions associated to the spin-statistics connections, and show that noncommutative N=4, U(1) gauge theory can be softly broken to N=0 satisfying the axioms and providing an example where the Wilsonian low energy effective action can be constructed without UV/IR problems, after a judicious choice of soft breaking parameters is made. We also assess the phenomenological prospects of such a theory, which are in fact rather negative.

description: We use observations of chlorine-bearing species in molecular absorbers at intermediate redshifts to investigate chemical properties and $^{35}$Cl/$^{37}$Cl isotopic ratios in the absorbing sightlines. Chloronium (H$_2$Cl$^+$) is detected along three independent lines of sight in the z=0.89 and z=0.68 molecular absorbers located in front of the lensed quasars PKS 1830-211 and B 0218+357, respectively. Hydrogen chloride (HCl) was observed only toward PKS 1830-211, and is found to behave differently from H$_2$Cl$^+$. It is detected in one line of sight with an abundance ratio [H$_2$Cl$^+$]/[HCl] $\sim 1$, but remains undetected in the other, more diffuse, line of sight, with a ratio [H$_2$Cl$^+$]/[HCl]~$>17$. The absorption profiles of these two chlorine-bearing species are compared to other species and discussed in terms of the physical properties of the absorbing gas. Our findings are consistent with the picture emerging from chemical models where different species trace gas with different molecular hydrogen fraction. The $^{35}$Cl/$^{37}$Cl isotopic ratios are measured in the different lines of sight and are discussed in terms of stellar nucleosynthesis.

description: Thermally excited waves in a Plasma crystal were numerically simulated using a Box_Tree code. The code is a Barnes_Hut tree code proven effective in modeling systems composed of large numbers of particles. Interaction between individual particles was assumed to conform to a Yukawa potential. Particle charge, mass, density, Debye length and output data intervals are all adjustable parameters in the code. Employing a Fourier transform on the output data, dispersion relations for both longitudinal and transverse wave modes were determined. These were compared with the dispersion relations obtained from experiment as well as a theory based on a harmonic approximation to the potential. They were found to agree over a range of 0.9

description: Light can be strongly confined in sub-wavelength spatial regions through the interaction with plasmons, the collective electronic modes appearing in metals and semiconductors. This confinement, which is particularly important in the terahertz spectral region, amplifies light-matter interaction and provides a powerful mechanism for efficiently generating non-linear optical phenomena. These effects are particularly relevant in Dirac materials like graphene and Topological Insulators, where massless fermions show a naturally non-linear optical behavior in the terahertz range. The strong interaction scenario has been considered so far from the point of view of light. In this paper, we investigate instead the effect of strong interaction on the plasmon itself. In particular, we will show that Dirac plasmons in Bi$_2$Se$_3$ Topological Insulator are strongly renormalized when excited by high-intensity terahertz radiation by displaying a huge red-shift down to 60% of its characteristic frequency. This opens the road towards tunable terahertz non-linear optical devices based on Topological Insulators.

description: An important condition for the efficient production and marketing of local food products in mountainous regions is broadly recognised in cooperation between different partners along the food supply chain. Cooperation between different actors, organisational forms and sectors is especially important in mountains and less favoured areas characterised by limited conditions for agriculture and, consequently, where few raw materials are produced. This article presents a study aimed at identifying the positive effects of cooperation between actors, organisational forms and sectors in the production and marketing system of local food products in the Slovenian mountains. Ten products were included in the study. The results indicate that the presence of the private sector both in the production and marketing system is an important condition for creating a successful and solid food supply chain.

description: Two-dimensional (2D) van der Waals (vdW) magnetic materials have recently been introduced as a new horizon in materials science and enable the potential applications for next-generation spintronic devices. Here, in this communication, the observations of stable Bloch-type magnetic skyrmions in single crystals of 2D vdW Fe3GeTe2 (FGT) are reported by using in-situ Lorentz transmission electron microscopy (TEM). We find the ground-state magnetic stripe domains in FGT transform into skyrmion bubbles when an external magnetic field is applied perpendicularly to the (001) thin plate with temperatures below the Curie-temperature TC. Most interestingly, a hexagonal lattice of skyrmion bubbles is obtained via field cooling manipulation with magnetic field applied along the [001] direction. Owing to their topological stability, the skyrmion bubble lattices are stable to large field-cooling tilted angles and further reproduced by utilizing the micromagnetic simulations. These observations directly demonstrate that the 2D vdW FGT possesses a rich variety of topological spin textures, being of a great promise candidate for future applications in the field of spintronics.

Rudimentary Exploration of the Concept of Action from Abstract Algebra and Basic Ring Theory aimed at Postulating Post-Quantum Computing Methods through Manipulation of Unknown Quantities as Applied to the Basic Concepts of Variables and Equations

Year: 2021

description: In this research paper, we explore the possibilities associated with solving equations for variables, starting off at the most basic monomial expressions. However, analyzing the various definitions of the term ‘variable,’ it can be deduced that no single definition is sufficient to suffice the needs of compiling all possible solutions for a variable at one place, given that the equation in question is observed and operated using a combination of computational mathematics and abstract algebra. Although there is sufficient scientific literature available on applications of abstract algebra and ring theory in this field, solving for variables that logically represent unknown quantities has remained a relatively neglected area of study. Moreover, in this paper, the notions of mathematical operation and group action have been used almost interchangeably, which may not be agreed upon by the conventional academic system. The paper finally aims at developing postulates over the progress of computational mathematics, with special stress on machine learning, beyond the scope of quantum computing and related sciences. Keywords: variables, abstract algebra, group action, unknown quantity, computation, quantum computing, digital computing
description: Assignment, existence, declaration, or identification of a variable is actually a state of 'false positive' since once it is held that a given variable would be representing some unknown quantity, then the very notion itself becomes an invariant for the equation in question and the rest of the mathematical operations concerned.

This study presents an evaluation of on-farm self-assessment using animal-based indicators to support fattening poultry farmers in managing the welfare of their animals. Self-assessment guidelines elaborated by a German expert group were evaluated together with 11 trained broiler and 11 trained turkey farmers. The participating farmers tested a protocol with 18 indicators for broilers and a protocol with 20 indicators for turkeys on their farms for 1 y. The reliability of individual animal scoring, the practicability of the protocols, their implementation, and acceptance were then evaluated. Reliability was tested during 2 farm visits by the accompanying scientists, using the scientist as a silver standard. On average, the farmers achieved very good reliability (mean PABAK - prevalence-adjusted and bias-adjusted kappa, broilers: 0.90; turkeys: 0.86), with no detectable influence of the previous training method (online versus in-person), the first versus the second visit of the scientists, the fattening stage of the animals scored, number of animals on the farm or the farmers’ professional background. The assessment took longer at the end of the fattening period for both animal species. On farms with more personnel and for farmers with a higher position on farm, the assessment was easier to integrate into their work. Most farmers did not fully document their self-assessment and almost no farmer processed and evaluated the data properly, even though it seemed interesting to them. Overall, there was only moderate acceptance of the welfare self-assessment approach, with mixed responses as to whether it provided early warning information or benefits to animal management. Farmers often pointed to the increased cost associated with carrying out self-assessments in terms of the additional working time required, which is likely to be an important barrier to continuing. Digital applications for data recording, processing and evaluation may help to overcome barriers. Overall, it appears unlikely that the welfare self-assessment approach will be widely implemented in the poultry fattening sector without further incentives.

description: Traceability is a modern concept that allows following a product’s route from raw materials to the selling stage, taking into consideration its complete flow by means of identifying and tracking procedures and documents. Recently, food traceability has gained significant importance as it allows efficient identification, correction or removal of risk factors throughout the food chain in order to deliver only safe and quality products to consumers. The paper aims to outline the main food traceability conceptual approaches and to highlight traceability key-elements and objectives in order to emphasize the significance of a traceability system for the food chain.

description: A subset $D\subseteq V_G$ is a dominating set of $G$ if every vertex in $V_G-D$ has a~neighbor in $D$, while $D$ is a paired-dominating set of $G$ if $D$ is a~dominating set and the subgraph induced by $D$ contains a perfect matching. A graph $G$ is a $D\!P\!D\!P$-graph if it has a pair $(D,P)$ of disjoint sets of vertices of $G$ such that $D$ is a dominating set and $P$ is a paired-dominating set of $G$. The study of the $D\!P\!D\!P$-graphs was initiated by Southey and Henning (Cent. Eur. J. Math. 8 (2010) 459--467; J. Comb. Optim. 22 (2011) 217--234). In this paper, we provide conditions which ensure that a graph is a $D\!P\!D\!P$-graph. In particular, we characterize the minimal $D\!P\!D\!P$-graphs.

description: The newly discovered exotic $Θ$ baryon of mass 1540 MeV (and very small width) truly has a very low mass, if it is a pentaquark system of even parity. A schematic model in which the coherent interaction of $u\bar s$ and $d\bar s$ pairs leads to a very large residual (non-confining) attractive interaction is introduced. This collective vibrational model accounts for the mass and small decay width to the $KN$ channel, but yields a significant coupling to the virtual $K^*N$ channel. The schematic model predicts an attractive $Θ$-nucleon interaction strong enough to bind a $Θ$ particle to a nucleus in a state that is stable against decay via strong interactions. The discovery of $Θ$-nuclei could be a definitive proof that the $Θ$ parity is even.

description: Certain quantum mechanical potentials give rise to a vanishing perturbation series for at least one energy level (which as we here assume is the ground state), but the true ground-state energy is positive. We show here that in a typical case, the eigenvalue may be expressed in terms of a generalized perturbative expansion (resurgent expansion). Modified Bohr-Sommerfeld quantization conditions lead to generalized perturbative expansions which may be expressed in terms of nonanalytic factors of the form exp(-a/g), where a > 0 is the instanton action, and power series in the coupling g, as well as logarithmic factors. The ground-state energy, for the specific Hamiltonians, is shown to be dominated by instanton effects, and we provide numerical evidence for the validity of the related conjectures.

description: Objective: To derive a closed-form analytical solution to the swing equation describing the power system dynamics, which is a nonlinear second order differential equation. Existing challenges: No analytical solution to the swing equation has been identified, due to the complex nature of power systems. Two major approaches are pursued for stability assessments on systems: (1) computationally simple models based on physically unacceptable assumptions, and (2) digital simulations with high computational costs. Motivation: The motion of the rotor angle that the swing equation describes is a vector function. Often, a simple form of the physical laws is revealed by coordinate transformation. Methods: The study included the formulation of the swing equation in the Cartesian coordinate system, which is different from conventional approaches that describe the equation in the polar coordinate system. Based on the properties and operational conditions of electric power grids referred to in the literature, we identified the swing equation in the Cartesian coordinate system and derived an analytical solution within a validity region. Results: The estimated results from the analytical solution derived in this study agree with the results using conventional methods, which indicates the derived analytical solution is correct. Conclusion: An analytical solution to the swing equation is derived without unphysical assumptions, and the closed-form solution correctly estimates the dynamics after a fault occurs.

Survey results from 2010 pointed out that poverty is widespread among people living in rural area (13.6%), particularly among children under 13 years of age (13.7%), in Central Serbia (12.0%), in multi-member households (16.4%) and in households where the head has a lower educational level (14,2%) or is unemployed (17.9%). The fact that poor live in rural areas should not lead to deterioration of the principle of equality in the rights for all citizens of the Republic of Serbia.

description: Dust particles immersed within a plasma environment, such as those in protostellar clouds, planetary rings or cometary environments, will acquire an electric charge. If the ratio of the inter-particle potential energy to the average kinetic energy is high enough the particles will form either a "liquid" structure with short-range ordering or a crystalline structure with long range ordering. Many experiments have been conducted over the past several years on such colloidal plasmas to discover the nature of the crystals formed, but more work is needed to fully understand these complex colloidal systems. Most previous experiments have employed monodisperse spheres to form Coulomb crystals. However, in nature (as well as in most plasma processing environments) the distribution of particle sizes is more randomized and disperse. This paper reports experiments which were carried out in a GEC rf reference cell modified for use as a dusty plasma system, using varying sizes of particles to determine the manner in which the correlation function depends upon the overall dust grain size distribution. (The correlation function determines the overall crystalline structure of the lattice.) Two dimensional plasma crystals were formed of assorted glass spheres with specific size distributions in an argon plasma. Using various optical techniques, the pair correlation function was determined and compared to those calculated numerically.

Holotype, female
 Type locality. French Guiana, Cayenne
 Remarks. The locality stated on the specimen label (Fig. 122b) indicates “Essequebo,” which may refer to Essequibo River, Guyana. Although the locality indicated in the original description (Cayenne) does not match the text on the specimen label, we consider this specimen the holotype for the following reasons: the specimen in Fig. 122a bears two labels indicating it is the “type” and the specimen closely matches Buquet’s original description, including length (25 mm) and width (11 mm) measurements.

description: Economic sanctions, production and economic drop, as well as impoverishment have significantly reduced capabilities of the state for investment in environmental protection, but as well environmental concerns of agricultural producers. However, compliance with mandatory standards and rules forming the corpus of agri-environmental measures and principles of good agricultural practice are an important step towards preservance of the environment and care about health of humans, plants and animals. On the other side, it is an important prerequisite for Serbian exports of agricultural products. In addition from mandatory rules, which are also relevant for fulfilment of the duty of cross-compliance for producers receiving direct payments, agri-environmental incentives as voluntary commitments of producers to provide a higher level of environmental protection are particularly welcome, but are hardly possible to give rise in the short term. The Paper gives a short overview of agri-environment policy in the EU and is mostly focused on mandatory rules setting duties and responsibilities of agricultural producers and issues related to approximation of Serbian legislative framework with the EU.

Parity of transversals of Latin squares

Subjects: subject: Combinatorics (math.CO)

description: We introduce a notion of parity for transversals, and use it to show that in Latin squares of order $2 \bmod 4$, the number of transversals is a multiple of 4. We also demonstrate a number of relationships (mostly congruences modulo 4) involving $E_1,\dots, E_n$, where $E_i$ is the number of diagonals of a given Latin square that contain exactly $i$ different symbols. Let $A(i\mid j)$ denote the matrix obtained by deleting row $i$ and column $j$ from a parent matrix $A$. Define $t_{ij}$ to be the number of transversals in $L(i\mid j)$, for some fixed Latin square $L$. We show that $t_{ab}\equiv t_{cd}\bmod2$ for all $a,b,c,d$ and $L$. Also, if $L$ has odd order then the number of transversals of $L$ equals $t_{ab}$ mod 2. We conjecture that $t_{ac} + t_{bc} + t_{ad} + t_{bd} \equiv 0 \bmod 4$ for all $a,b,c,d$. In the course of our investigations we prove several results that could be of interest in other contexts. For example, we show that the number of perfect matchings in a $k$-regular bipartite graph on $2n$ vertices is divisible by $4$ when $n$ is odd and $k\equiv0\bmod 4$. We also show that $${\rm per}\, A(a \mid c)+{\rm per}\, A(b \mid c)+{\rm per}\, A(a \mid d)+{\rm per}\, A(b \mid d) \equiv 0 \bmod 4$$ for all $a,b,c,d$, when $A$ is an integer matrix of odd order with all row and columns sums equal to $k\equiv2\bmod4$.
Tensionless Strings, WZW Models at Critical Level and Massless Higher Spin Fields

description: We discuss the notion of tensionless limit in quantum bosonic string theory, especially in flat Minkowski space, noncompact group manifolds (e.g., SL(2,R)) and coset manifolds (e.g., AdS). We show that in curved space typically there exists a critical value of the tension which is related to the critical value of the level of the corresponding affine algebra. We argue that at the critical level the sring theory becomes tensionless and that there exists a huge new symmetry of the theory. We dicuss the appearence of the higher spin massless states at the critical level.

description: This work explored an element-wise approach to model transcranial MRI-guided focused ultrasound (TcMRgFUS) thermal ablation, a noninvasive approach to neurosurgery. Each element of the phased array transducer was simulated individually and could be simultaneously loaded into computer memory, allowing for rapid calculation of the pressure field for different phase offsets used for beam steering and aberration correction. We simulated the pressure distribution for 431 sonications in 32 patients, applied the phase and magnitude values used during treatment, and estimated the resulting temperature rise. We systematically varied the relationship between CT-derived skull density and the acoustic attenuation and sound speed to obtain the best agreement between the predictions and MR temperature imaging (MRTI). The optimization was validated with simulations of 396 sonications from 40 additional treatments. After optimization, the predicted and measured heating agreed well (R2: 0.74 patients 1-32; 0.71 patients 33-72). The dimensions and obliquity of the heating in the simulated temperature maps correlated well with the MRTI (R2: 0.62, 0.74 respectively), but the measured heating was more spatially diffuse. The energy needed to achieve ablation varied by an order of magnitude (3.3-36.1 kJ). While this element-wise approach requires more computation time up front, it can be performed in parallel. It allows for rapid calculation of the three-dimensional heating at the focus for different phase and magnitude values on the array. We also show how this approach can be used to optimize the relationship between CT-derived skull density and acoustic properties. While the relationships found here need further validation in a larger patient population, these results demonstrate the promise of this approach to model TcMRgFUS.

description: We have studied the high-mass star-forming complex NGC 6334 with ALMA in the continuum emission at a frequency of 87.6 GHz, achieving a spatial resolution of 1300 au. Detecting 142 compact sources distributed over the whole observed area, we then used machine learning algorithms to group the compact cores in different clusters. A total of four main clusters were identified: NGC 6334-E, NGC 6334-I, NGC 6334-I(N) and NGC 6334-I(NW). The typical separations between cluster members (4000-12000 au) together with the core masses (0.2-100 $M_{\odot}$) are in agreement with turbulent fragmentation at scales of 0.1 pc. We find that the CMFs (core mass functions) show an excess of massive cores compared to the IMF. Typical uncertainties in temperature or unresolved multiplicity may mimic the observed excess of massive cores. Evidence of mass segregation in NGC 6334-I and NGC 6334-I(N), with the most massive cores located closer to the center, was found. Correlations between the physical properties of the clusters and their evolutionary stage were searched for, and found to show a larger separation between cores in the more evolved clusters, favouring the role of gas expulsion and stellar ejection over time. From these results, we suggest that NGC 6334-I(N) was primordially segregated, while NGC 6334-I may have become mass-segregated over time due to dynamical effects. Finally, the lack of massive cores in the most evolved cluster suggests that the gas reservoir may be already exhausted, while the less evolved clusters still have access to a larger gas mass reservoir. In general, the fragmentation in NGC 6334 at large scales (about 1 pc) is governed by turbulent pressure, while at smaller scales (a few hundred au), thermal pressure regulates the fragmentation process.
